Technical Field
The present disclosure relates generally to wireless communication networks, and more particularly, to methods and apparatus for communicating uplink control information in a wireless communication system.
Background
With the rapid increase in demand for large amounts of data to and from mobile communication devices, conventional mobile voice communication networks evolve into networks that communicate with internet protocol (Internet Protocol, IP) data packets. This IP packet communication may provide voice over IP, multimedia, multicast, and on-demand communication services to users of mobile communication devices.
An exemplary network structure is an evolved universal terrestrial radio access network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN). The E-UTRAN system may provide high data throughput for implementing the above-described IP-bearing voice and multimedia services. Currently, the 3GPP standards organization is discussing new next generation (e.g., 5G) radio technologies. Thus, changes to the current body of the 3GPP standard are currently being submitted and considered to evolve and complete the 3GPP standard.

Detailed Description
The exemplary wireless communication systems and apparatus described below employ wireless communication systems that support broadcast services. Wireless communication systems are widely deployed to provide various types of communication such as voice, data, and so on. These systems may be Code Division Multiple Access (CDMA), time Division Multiple Access (TDMA), orthogonal Frequency Division Multiple Access (OFDMA), 3 rd generation partnership project (3 GPP) long term evolution (Long Term Evolution, LTE) wireless access, 3GPP long term evolution advanced (Long Term Evolution Advanced, LTE-a), 3GPP2 ultra mobile broadband (Ultra Mobile Broadband, UMB), wiMax, 3GPP New Radio (NR) wireless access for 5G, or some other modulation technique.

Fig. 1 presents a multiple access wireless communication system in accordance with one or more embodiments of the present disclosure. The access network 100 (AN) includes multiple antenna groups, one including 104 and 106, another including 108 and 110, and yet another including 112 and 114. In fig. 1, only two antennas are shown for each antenna group, but more or fewer antennas may be utilized for each antenna group. Access terminal 116 (AT) is in communication with antennas 112 and 114, where antennas 112 and 114 transmit information to access terminal 116 over forward link 120 and receive information from access terminal 116 over reverse link 118. AT 122 communicates with antennas 106 and 108, where antennas 106 and 108 transmit information to AT 122 over forward link 126 and receive information from AT 122 over reverse link 124. In a frequency-division duplex (FDD) system, communication links 118, 120, 124 and 126 can use different frequencies for communication. For example, forward link 120 may use a different frequency than that used by reverse link 118.
The antennas of each group and/or the area in which they are designed to communicate are often referred to as a sector of the access network. In an embodiment, antenna groups each may be designed to communicate to access terminals in a sector of the areas covered by access network 100.
In communication over forward links 120 and 126, the transmit antennas of access network 100 may utilize beamforming in order to improve signal-to-noise ratio of forward links for the different access terminals 116 and 122. Also, an access network using beamforming to transmit to access terminals scattered randomly through its coverage typically causes less interference to access terminals in neighboring cells than an access network transmitting through a single antenna to all its access terminals.
AN Access Network (AN) may be a fixed station or base station used for communicating with the terminals and may also be referred to as AN access point, a Node B, a base station, AN enhanced base station, AN eNodeB (eNB), a next-generation NodeB (gNB), or some other terminology. An Access Terminal (AT) may also be referred to as a User Equipment (UE), a wireless communication device, a terminal, an access terminal, or some other terminology.
Fig. 2 presents an embodiment of a transmitter system 210 (also referred to as an access network) and a receiver system 250 (also referred to as an Access Terminal (AT) or User Equipment (UE)) in a multiple-input multiple-output (MIMO) system 200. At the transmitter system 210, traffic data for a number of data streams may be provided from a data source 212 to a Transmit (TX) data processor 214.
In one embodiment, each data stream is transmitted through a respective transmit antenna. TX data processor 214 formats, codes, and interleaves the traffic data for each data stream based on a particular coding scheme selected for that data stream to provide coded data.
The decoded data for each data stream may be multiplexed with pilot data using orthogonal frequency division multiplexing (orthogonal frequency-division multiplexing, OFDM) techniques. The pilot data may generally be a known data pattern that is processed in a known manner and may be used at the receiver system to estimate the channel response. The multiplexed pilot and coded data for each data stream can then be modulated (i.e., symbol mapped) based on a particular modulation scheme (e.g., binary phase-shift keying (binary phase shift keying, BPSK), quadrature phase-shift keying (quadrature phase shift keying, QPSK), M-ary phase-shift keying (M-ary phase shift keying, M-PSK), or M-ary quadrature amplitude modulation (M-ary quadrature amplitude modulation, M-QAM) selected for that data stream to provide modulation symbols. The instructions executed by processor 230 may determine a data rate, coding, and/or modulation for each data stream.
The modulation symbols for the data streams are then provided to a TX MIMO processor 220, which may further process the modulation symbols (e.g., for OFDM). TX MIMO processor 220 then applies N T Providing the modulated symbol streams to N T Transmitters (TMTR) 222a through 222t. In certain embodiments, TX MIMO processor 220 may apply beamforming weights to the symbols of the data streams and to the antenna from which the symbol is being transmitted.
Each transmitter 222 receives and processes a respective symbol stream to provide one or more analog signals, and further conditions (e.g., amplifies, filters, and/or upconverts) the analog signals to provide a modulated signal suitable for transmission over the MIMO channel. Next, one can separately select from N T The antennas 224a through 224t transmit N from the transmitters 222a through 222t T A modulated signal.
At the receiver system 250, the signal is represented by N R Each antenna 252 a-252 r receives the transmitted modulated signals and the signals received from each antenna 252 may be provided to a respective receiver (RCVR) 254 a-254 r. Each receiver 254 may condition (e.g., filter, amplify, and downconvert) a respective received signal, digitize the conditioned signal to provide samples, and/or further process the samples to provide a corresponding "received" symbol stream.
RX data processor 260 then transmits the data to N R The individual receivers 254 receive and/or process N based on a particular receiver processing technique R Providing N by receiving symbol streams T A "detected" symbol stream. RX data processor 260 may then demodulate, deinterleave, and/or decode each detected symbol stream to recover the traffic data for the data stream. The processing by RX processor 260 can be complementary to that performed by TX MIMO processor 220 and TX data processor 214 at transmitter system 210.
Processor 270 may periodically determine which pre-coding matrix to use (discussed below). Processor 270 formulates a reverse link message comprising a matrix index portion and a rank value portion.
The reverse link message may comprise various types of information regarding the communication link and/or the received data stream. The reverse link message may then be processed by a TX data processor 238 (which may also receive traffic data for a number of data streams from a data source 236), modulated by a modulator 280, conditioned by transmitters 254a through 254r, and/or transmitted back to transmitter system 210.
At transmitter system 210, the modulated signals from receiver system 250 are received by antennas 224, conditioned by receivers 222, demodulated by a demodulator 240, and processed by a RX data processor 242 to extract the reverse link message transmitted by receiver system 250. Processor 230 may then determine which pre-coding matrix to use to determine the beamforming weights and may then process the extracted message.
Fig. 3 presents an alternative simplified functional block diagram of a communication device in accordance with an embodiment of the disclosed subject matter. As shown in fig. 3, a communication apparatus 300 in a wireless communication system may be utilized for implementing UEs (or ATs) 116 and 122 in fig. 1 or a base station (or AN) 100 in fig. 1, and the wireless communication system may be AN LTE system or AN NR system. The communication device 300 may include an input device 302, an output device 304, a control circuit 306, a central processing unit (central processing unit, CPU) 308, a memory 310, program code 312, and a transceiver 314. The control circuit 306 executes the program code 312 in the memory 310 via the CPU 308, thereby controlling the operation of the communication device 300. The communication device 300 may receive signals input by a user through an input device 302 (e.g., a keyboard or keypad) and may output images and sounds through an output device 304 (e.g., a monitor or speaker). The transceiver 314 is used to receive and transmit wireless signals, pass the received signals to the control circuit 306, and wirelessly output signals generated by the control circuit 306. The AN 100 of fig. 1 may also be implemented with a communication device 300 in a wireless communication system.
Fig. 4 is a simplified block diagram of program code 312 shown in fig. 3 according to one embodiment of the disclosed subject matter. In this embodiment, program code 312 includes an application layer 400, a layer 3 portion 402, and a layer 2 portion 404, and is coupled to a layer 1 portion 406. Layer 3 portion 402 may perform radio resource control. Layer 2 portion 404 may perform link control. Layer 1 portion 406 may perform and/or implement physical connections.
The reasons and/or goals for Multiple Input Multiple Output (MIMO) in release 18 (Rel-18) are discussed in RP-213598. One or more portions of RP-213598 are referenced below:
reason 3
MIMO is one of the key technologies in NR systems and has been successful in commercial deployment. In Rel-15/16/17, MIMO features are studied and specified for both FDD and TDD systems, with a major portion being used for downlink MIMO operation. In Rel-18, it is important to identify and specify the necessary enhancements for uplink MIMO, while the necessary enhancements for downlink MIMO that facilitate the use of large antenna arrays, not only for FR1 but also for FR2, will still need to be introduced to achieve the evolving request for NR deployment. This includes the following enhancement regions.
First, significant loss of performance of the UE at high/medium speed has been observed in commercial deployments, especially in multi-user MIMO (MU-MIMO) scenarios. Since performance loss is caused in part by outdated CSI, it may be beneficial to enhance CSI acquisition to mitigate such loss. Second, the unified TCI framework is introduced into Rel-17 which facilitates streamlined operations targeting FR 2. Since Rel-17 focuses on single TRP use cases, an extension of the unified TCI framework focusing on multiple TRP use cases is beneficial. Third, since the demand for multiplexing capacity of downlink and uplink demodulation reference signals (demodulation reference signal, DMRS) from various use cases increases, the number of orthogonal ports for DMRS needs to be increased. Fourth, features for facilitating multi-TRP deployment have been introduced into Rel-16/17, which focuses on non-coherent joint transmission (non-coherent joint transmission, NC-JT). Since coherent joint transmission (cqt) improves coverage and average throughput in commercial deployments through high-performance backhaul and synchronization, enhancing CSI acquisition for FDD and TDD for FR1 is beneficial to extend the utility of multi-TRP deployments. Fifth, as advanced UEs (e.g., CPE, FWA, vehicle, industrial devices) become more relevant, introducing the necessary enhancements to support 8 antenna ports and 4 and more layers for UL transmissions can provide the desired improvements in UL coverage and average throughput. Sixth, by introducing features for UL panel selection in Rel-17, advanced UEs (e.g., CPE, FWA, vehicle, industrial devices) can benefit from higher UL coverage and average throughput by simultaneous UL multi-panel transmission. Finally, some further enhancements to facilitate UL multi-TRP deployment via two Timing Advances (TAs) and to enhance UL power control may provide additional UL performance improvements.
4 target
4.1 targets of SI or core part WI or test part WI
The detailed objectives are as follows:
RAN1：
1. if desired, studies specify the following to facilitate simultaneous multi-panel UL transmissions to achieve higher UL throughput/reliability, with a focus on FR2 and multiple TRPs, assuming a maximum of 2 TRPs and a maximum of 2 panels, for CPE/FWA/vehicle/industrial equipment (if applicable)
UL precoding indication of PUSCH without introducing new codebooks for multi-panel simultaneous transmission
Considering multi-TRP operation based on single DCI and multi-DCI, the total number of layers of all panels is at most four, and the total number of codewords of all panels is at most two.

9 UE procedure for reporting control information
…
If UE
-the first CORESET on the active DL BWP not provided with corespoolindex or for the serving cell is provided with corespoolindex having a value of 0, and
-the second CORESET on the active DL BWP for the serving cell is provided with a coresetpoolndex having a value of 1, and
-provided ackNackFeedbackMode = separation
The procedure described in clauses 9.1 and 9.2.3 should be applied separately by the UE for reporting HARQ-ACK information associated with a first CORESET on the active DL BWP of the serving cell and for reporting HARQ-ACK information associated with a second CORESET on the active DL BWP of the serving cell, and the UE is not expected to be provided with a subslotLengthfortpucch or to be indicated by the pdsch-HARQ-ACK-codebook list to generate two HARQ-ACK codebooks on the active DL BWP of the serving cell. The HARQ-ACK information report is associated with CORESET through reception of PDCCH with DCI format triggering the UE to report the HARQ-ACK information.
…
PUSCH or PUCCH transmissions other than PUCCH transmissions with SL HARQ-ACK reporting, including repetition (if present), may have priority index 0 or priority index 1. For configured grant PUSCH transmissions, the UE determines the priority index from the phy-PriorityIndex (if provided). For PUCCH transmissions with HARQ-ACK information corresponding to SPS PDSCH reception or SPS PDSCH release, the UE determines the priority index from the HARQ-codebook id (if provided). For PUCCH transmission with SR, the UE determines the corresponding priority as described in clause 9.2.4. For PUSCH transmissions with semi-persistent CSI reports, the UE determines the priority index from a priority indicator field (if provided) in the DCI format that activates the semi-persistent CSI report. If the priority index is not provided to the UE for PUSCH or PUCCH transmission other than PUCCH transmission with SL HARQ-ACK report, the priority index is 0.
If the UE is provided with subslotLengthForPUCCH in PUCCH-Config with a given priority index, then there is HARQ-ACK in the presence of the UESymbol [4, TS 38.211]The UE does not expect HARQ-ACK information received (if present) or SR (if present) in response to SPS PDSCH only with a given priority index in a slot of the subslotLengthForPUCCH symbol to move to a different slot of the subslotLengthForPUCCH symbol after multiplexing the overlapping PUCCHs.
The priority index may be provided by a priority indicator field if the UE monitors the PDCCH to detect DCI formats including the priority indicator field in the active DL BWP. If the UE indicates the ability to monitor PDCCH in the active DL BWP to detect a DCI format including a priority indicator field, the DCI format may schedule PUSCH transmission or PDSCH reception of any priority and/or trigger PUCCH transmission of corresponding HARQ-ACK information of any priority, and DCI format 1_1 or DCI format 1_2 may indicate TCI status update and trigger PUCCH transmission of corresponding HARQ-ACK information of any priority.
If UE
-a PUCCH with a first priority index and a PUSCH with a second priority index different from the first priority index are provided and transmitted, wherein PUCCH and PUSCH overlap in time
PUCCH and PUSCH [18, ts 38.306] may be transmitted simultaneously,
the UE excludes PUSCH to account for temporal overlap between PUCCH and PUSCH, where no timeline condition is required for the excluded PUSCH.
When the UE determines overlap of PUCCH and/or PUSCH transmissions with different priority indexes in addition to PUCCH transmissions with SL HARQ-ACK reports, including repetition (if present) before considering the restrictions on transmissions as described in clause 11.1 and clause 11.1.1, if the UE is provided UCI-muxwithdifferientpriority and the timeline condition for multiplexing UCI in PUCCH or PUSCH in clause 9.2.5 is satisfied,
first, the UE addresses overlapping of PUCCH and/or PUSCH transmissions with the same priority index as described in clauses 9.2.5 and 9.2.6
Second, the UE solves the overlap of PUCCH transmissions with different priority indexes, and
-if the UE is provided subslotLengthForPUCCH in the second PUCCH-Config, then the PUCCH transmission with the smaller priority index is associated with the first overlapping slot of the subslotLengthForPUCCH symbol with the larger priority index; otherwise, PUCCH transmissions with smaller priority index and PUCCH transmissions with larger priority indexSymbol [4, TS 38.211]Is associated with overlapping time slots.
The UE first and then subsequently describes resolving PUCs within timeslots (if present) with larger priority indices as inCH transmissions (at least one of the PUCCH transmissions hasRepetition), and then the UE uses the pseudo code in clause 9.2.5 to resolve the overlap of PUCCH transmissions without repetition within the slot
-if the UE determines not to discard the UCI of the first PUCCH transmission with the smaller priority index and not to multiplex the first PUCCH transmission in the second PUCCH transmission with the larger priority index in the overlapping slot with the subslotLengthForPUCCH symbol, the first PUCCH transmission is associated with the next overlapping slot with the subslotLengthForPUCCH symbol for the PUCCH transmission with the larger priority index
UE does not expect PUCCH transmissions containing UCI with different priority index and PUCCH transmissions with UCI with repetition within a slot after accounting for overlap of non-repeated PUCCH transmissions within the slotRepeated PUCCH transmission overlap
-the UE does not expect PUCCH transmissions of UCI with first and second priority indices to overlap with PUCCH transmissions of HARQ-ACK information with first priority index, or with PUCCH transmissions, or with PUSCH transmissions with second priority index when the second priority index is greater than the first priority index
The UE does not expect that PUCCH transmission of HARQ-ACK information with larger priority index overlaps with more than one PUCCH transmission of HARQ-ACK information with smaller priority index
Third, the UE addresses overlapping of PUCCH and PUSCH transmissions with different priority indexes
-the UE discarding PUSCH transmissions with smaller priority index overlapping PUCCH transmissions with larger priority index positive SR before PUSCH transmission with smaller priority index multiplexes UCI (if present)
UE discards the UE with larger priority index before multiplexing UCI (if present) in PUSCH transmission with smaller priority indexOverlapping PUSCH transmissions with smaller priority index for repeated PUCCH transmissions
-the UE multiplexing HARQ-ACK information in PUSCH transmissions, such that the clauses are described later in relation to multiplexing HARQ-ACK information from PUCCH transmissions in PUSCH transmissions with the same priority index, if a PUCCH transmission of HARQ-ACK information with a first priority index overlaps with one or more PUSCH transmissions with a second priority index different from the first priority index
-if// this is for the case where the UE supports multiplexing information of different priorities in PUCCH/PUSCH transmissions
-a non-repeated PUCCH transmission with HARQ-ACK information with a smaller priority index overlaps with a non-repeated PUCCH transmission with HARQ-ACK information only with a larger priority index, or
-a repetition-free PUCCH transmission containing HARQ-ACK information with a smaller priority index overlaps with a repetition-free PUCCH transmission using PUCCH resources with PUCCH format 2/3/4 of HARQ-ACK information with a larger priority index and SR, or

UE
Transmitting PUCCH or PUSCH with larger priority index, and
-not transmitting PUCCH or PUSCH with smaller priority index
When the UE determines overlap of PUCCH and/or PUSCH transmissions with different priority indexes, in addition to PUCCH transmissions with SL HARQ-ACK reporting, before considering restrictions (if any) on transmissions containing repetitions, as described in clauses 11.1 and 11.1.1, if the UE is not provided with UCI-muxwithdiff identity, the UE first resolves overlap of PUCCH and/or PUSCH transmissions with smaller priority indexes, as described in clauses 9.2.5 and 9.2.6. Subsequently, the first and second heat exchangers are connected,
-if a transmission of a first PUCCH with a larger priority index scheduled by a DCI format in PDCCH reception is to overlap in time with a repetition of a transmission of a second PUSCH or a second PUCCH with a smaller priority index, the UE cancelling the repetition of the transmission of the second PUSCH or the second PUCCH before a first symbol to be overlapped with the first PUCCH transmission

Wherein the method comprises the steps of
Before or after addressing the overlap (if any) between channels with larger priority indices, overlap applies, as described in clauses 9.2.5 and 9.2.6

5.1 UE procedure for receiving physical downlink shared channel
…
If the UE is configured by a higher layer parameter PDCCH-Config containing two different values of coresetpoolndex in the controlresource set, it may be desirable for the UE to receive multiple PDCCHs scheduling PDSCH that are fully overlapping/partially overlapping/non-overlapping in the time and frequency domains. The UE may expect to receive PDSCH that overlap/partially overlap in time only when PDCCH scheduling two PDSCH are associated with different controlresources with different values of corespololndex. For ControlResourceSet, UE without corespoolindex, it can be assumed that ControlResourceSet is assigned a corespoolindex of 0. When the UE is configured with [ numberofadditionpci ], the ControlResourceSets corresponding to the different corespoolindex values may be associated with different physical cell IDs via the activated TCI state of the ControlResourceSets, where the ControlResourceSets corresponding to one corespoolindex may be associated with one physical cell ID and the ControlResourceSets corresponding to another corespoolindex may be associated with another physical cell ID. When the PDSCH is fully overlapped/partially overlapped/non-overlapped in the time and frequency domains to schedule the UE, full scheduling information for receiving the PDSCH is indicated and carried only by the corresponding PDCCH, it is desirable to schedule the UE with the same active BWP and the same SCS. When the PDSCH is fully/partially overlapped in the time and frequency domains to schedule the UE, at most two codewords may be simultaneously used to schedule the UE.
5.1.5 antenna Port quasi co-location
The UE may be configured with a list of up to M TCI-State configurations within the higher layer parameters PDSCH-Config to decode PDSCH according to detected PDCCH with DCI intended for the UE and a given serving cell, where M depends on UE capability maxnumberconfiguredtricistateper cc. Each TCI-State contains parameters for configuring a quasi co-sited relationship between one or two downlink reference signals and a DM-RS port of PDSCH, a DM-RS port of PDCCH, or a CSI-RS port of CSI-RS resource. The quasi co-sited relationship is configured by the higher layer parameters qcl-Type1 for the first DL RS and the higher layer parameters qcl-Type2 for the second DL RS (if configured). In case of two DL RSs, the QCL type will be different, irrespective of whether the reference is for the same DL RS or different DL RSs. The quasi co-location Type corresponding to each DL RS is given by the higher layer parameter QCL-Type in the QCL-Info and may take one of the following values:
- 'type a': { Doppler shift, doppler spread, average delay, delay spread }
- 'type B': { Doppler shift, doppler spread }
- 'type C': { Doppler shift, average delay }
- 'type D': { spatial Rx parameters })
The UE may be configured with a list of up to 128 dlorjointtcisttate configurations within the higher layer parameters PDSCH-Config for providing quasi co-located reference signals for DM-RS of PDSCH in the CC and DMR-S of PDCCH for CSI-RS and, where applicable, for providing a reference for determining UL TX spatial filters for PUSCH and PUCCH resources and SRS in the CC based on dynamic grants and configured grants.
If the DLorJointTCIState or UL-TCIState configuration does not exist in the BWP of the CC, the UE may apply the DLorJointTCIState or UL-TCIState configuration from the reference BWP of the reference CC. If the UE is configured with DLorJointTCIState or UL-TCIState in any CC in the band, then the UE is not expected to be configured with TCI-State, spatialRelationInfo or PUCCH-SpatialRelationInfo, spatialRelationInfoPos in the CC in the same band. The UE may assume that when the UE is configured with TCI-State in any of the CCs configured by simultaneousTCI-UpdateList1-r16, simultaneousTCI-UpdateList2-r16, simultaneousSpatail-UpdList 1-r16, or simultaneousSpatail-Updistelist 2-r16, the UE is not configured with DLorJointTCIState or UL-TCIState in any of the CCs within the same frequency band in the CC list.
The UE receives an activate command as described in clause 6.1.3.14 of [10, ts 38.321] or 6.1.3.X of [10, ts 38.321] for mapping up to 8 TCI states and/or pairs of TCI states to code points for a DCI field 'transmit configuration indication' for one or a group of CCs/DL BWP and (if applicable) for one or a group of CCs/UL BPW, one TCI state for DL channel/signal and one TCI state for UL channel/signal. When a set of TCI state IDs is activated for a CC/DL BWP set and (if applicable) for a CC/UL BWP set, wherein the applicable list of CCs is determined by the CC indicated in the activation command, the same set of TCI state IDs is applied for all DL and/or UL BWP in the indicated CC. If the activate command maps DLorJointTCIState and/or UL-TCIState to only one TCI code point, once the indicated mapping for the one single TCI code point is applied as described in [11, ts 38.133], the UE should apply the indicated DLorJointTCIState and/or UL-TCIState to one CC/DL BWP or set thereof and, if applicable, to one CC/UL BWP or set thereof.
When BWP-id or cell of the QCL-TypeA/D source RS in QCL-Info configured with the TCI state of DLorJointTCIState is not configured, the UE assumes that the QCL-TypeA/D source RS is configured in CC/DL BWP, where the TCI state applies.
When tci-PresentInDCI is set to 'Enable' or tci-PresentDCI-1-2 is configured for CORESET, a UE with an activated DLorJointTCIState or UL-TCIState receives DCI format 1_1/1_2, which provides the indicated DLorJointTCIState or UL-TCIState for one or all of the CCs in the same CC list configured by simultaneousTCI-UpdateList1-r17, simultaneousTCI-UpdateList2-r17, simultaneousTCI-UpdateList3-r17, simultaneousTCI-UpdateList4-r 17. DCI format 1_1/1_2 may or may not have (if applicable) DL assignment. If DCI format 1_1/1_2/no DL assignment, the UE may assume the following:
-CS-RNTI for scrambling CRC of DCI
-setting the values of the following DCI fields as follows:
-RV = all '1'
MCS = all '1'
-NDI＝0
Set to all '0' for FDRA type 0, or set to all '1' for FDRA type 1, or set to all '0' for dynamicSwitch (same as in tables 10.2-4 of [6, ts 38.213 ]).
…
If the UE is configured with SSB-MTC-addationpci and PDCCH-Config containing two different corespoolindex values in the ControlResourceSet, the UE receives an activate command of coresolindex associated with each corespoolindex as described in clause 6.1.3.14 of [10, ts 38.321] for mapping up to 8 TCI states to the code point of the DCI field "transmit configuration indication" in one CC/DL BWP. When a set of TCI state IDs is activated for one coresetpoolndex, the activated TCI state corresponding to one coresetpoolndex may be associated with one physical cell ID and the activated TCI state corresponding to another coresetpoolndex may be associated with another physical cell ID.
6.1 UE procedure for transmitting physical uplink shared channel
When the UE is configured with DLorJointTCIState or UL-TCIState, the UE should perform PUSCH transmission corresponding to Type 1 configured grant or Type 2 configured grant or dynamic grant according to spatial relationship (if applicable), with reference to RS for determining UL Tx spatial filter or RS configured with qcl-Type set to 'Type D' of indicated DLorJointTCIState or UL-TCIState.
6.1.1.2 non-codebook based UL transmissions
…
When two SRS resource sets are configured in SRS-resourcesetteto addmodlist or SRS-resourcesetteto addmodlist dci-0-2 with higher layer parameter usages in SRS-ResourceSet set to 'codebook' or 'non-codebook', the same symbol allocation is applied across K consecutive slots in case of K >1 for PUSCH repetition type a, and PUSCH is limited to a single transport layer. The UE should repeat the TB across K consecutive slots applying the same symbol allocation in each slot, and the association of the first and second SRS resource sets in SRS-resourcesetteto addmodlist or SRS-resourcesetteto addmodlistdi-0-2 to each slot is determined as follows:
if DCI format 0_1 or DCI format 0_2 indicates a code point "00" for an SRS resource set indicator, the first SRS resource set is associated with all K consecutive slots,
If DCI format 0_1 or DCI format 0_2 indicates a code point "01" for an SRS resource set indicator, the second SRS resource set is associated with all K consecutive slots,
-if DCI format 0_1 or DCI format 0_2 indicates a code point "10" for an SRS resource set indicator, the association of the first and second SRS resource sets to K consecutive slots is determined as follows:
when k=2, the first and second SRS resource sets are applied to the first and second slots of the 2 consecutive slots, respectively.
When K >2 and periodicity mapping in PUSCH-Config is enabled, the first and second SRS resource sets are applied to the first and second slots of the K consecutive slots, respectively, and the same SRS resource set mapping mode continues to the remaining slots of the K consecutive slots.
-when K >2 and sequentialMapping in PUSCH-Config is enabled, the first SRS resource set is applied to the first and second slots of K consecutive slots and the second SRS resource set is applied to the third and fourth slots of K consecutive slots and the same SRS resource set mapping mode continues to the remaining slots of K consecutive slots.
Otherwise, DCI format 0_1 or DCI format 0_2 indicates a code point "11" for an SRS resource set indicator, and the association of the first and second SRS resource sets to K consecutive slots is determined as follows,
When k=2, the second and first SRS resource sets are applied to the first and second slots of the 2 consecutive slots, respectively.
When K >2 and periodicity mapping in PUSCH-Config is enabled, the second and first SRS resource sets are applied to the first and second slots of the K consecutive slots, respectively, and the same SRS resource set mapping mode continues to the remaining slots of the K consecutive slots.
-when K >2 and sequentialMapping in PUSCH-Config is enabled, the second SRS resource set is applied to the first and second slots of the K consecutive slots and the first SRS resource set is applied to the third and fourth slots of the K consecutive slots and the same SRS resource set mapping mode continues to the remaining slots of the K consecutive slots.
…
For PUSCH repetition type a, when DCI format 0_1 and DCI format 0_2 indicate a code point "10" or "11" for SRS resource set indicator and aperiodic CSI report is scheduled on PUSCH with a transport block through 'CSI request' field on DCI, CSI report multiplexing is determined as follows
-transmitting the CSI report solely on only a first transmission occasion associated with the first SRS resource set and a first transmission occasion associated with the second SRS resource set if the higher layer parameter AP-CSI-multiplexing mode in the CSI-associtreportconfigmnfo is enabled and UCI other than the CSI report is not multiplexed on PUSCH.
Otherwise, transmitting CSI reports only on the first transmission occasion.

6.1.2.3 resource allocation for uplink transmissions with configured grants
When PUSCH resource allocation is semi-statically configured by the higher-layer parameters configuredGrantConfig in the BWP-uplink restricted information element and PUSCH transmission corresponds to a configured grant, the following higher-layer parameters are applied in the transmission:
for type 1PUSCH transmissions with configured grants, the following parameters are given in configurable grantconfigure unless mentioned otherwise:
…
…
-for type 2PUSCH transmissions with configured grants: the resource allocation follows a higher layer configuration according to [10, ts 38.321], and UL grants are received on the DCI.
The PUSCH repetition type and the time domain resource allocation table are determined by the PUSCH repetition type and the time domain resource allocation table, respectively, associated with the UL grant received on the DCI, as in clause 6.1.2.1Defined as follows. When determining the first transmission opportunity, apply K Offset of If configured).
For PUSCH transmissions with type 1 or type 2 configured grants, if numberofrepetition exists in the time domain resource allocation table, the (nominal) number of repetitions K to be applied to the transmitted transport block is provided by the indexed row in the table; otherwise K is provided by the higher layer configuration parameter repK.
For PUSCH transmissions with type 1 configured grants, when two SRS resource sets are configured in SRS-ResourceSetToAddModList or SRS-resourcesettoaddmodlistdi-0-2, PUSCH repetition is only associated with the first SRS resource set if configurable grantconfigug contains only one pathlossReferenceIndex, p-PUSCH-Alpha, powerControlLoopToUse, SRS-ResourceIndicator and predictingannumoflayers (applicable when higher layer parameter usages in SRS-ResourceSet are set to 'codebook').

One, some, and/or all of the following terms and assumptions may be used below.
Base Station (BS): a network central unit and/or a network node in a New Radio (NR) to control one or more transmission and/or reception points (TRP) associated with one or more cells. Communication between the base station and one or more TRPs may be via backhaul. A base station may be referred to as a Central Unit (CU), an eNB, a gNB, and/or a node B.
TRP: the TRP may provide network coverage and/or may communicate directly with the UE. TRP may be referred to as a Distributed Unit (DU) and/or a network node.
Cell: a cell includes one or more associated TRPs (e.g., the coverage area of a cell may include the coverage area of some and/or all of the associated TRPs). One cell may be controlled by one base station. A cell may be referred to as a TRP group (TRPG).
In NR Rel-15/16 (NR versions 15 and/or 16), the UE may perform uplink transmission via one UE panel. In NR Rel-17 (NR version 17), a UE may perform uplink transmission via multiple UE panels in a Time Division Multiplexing (TDM) mechanism (in order to meet, for example, strict reliability requirements). For example, the UE may perform uplink transmissions via an active UE panel in one timing sequence (e.g., one slot). By transmitting on different UE panels, the reliability of the transmission may be improved (and/or the transmission may meet stricter reliability requirements). However, in NR Rel-18 (NR version 18), higher levels of uplink transmission can be considered by introducing more services requiring high data rates. In some embodiments, multiple UE panels may be used for parallel (e.g., simultaneous) uplink transmissions to provide higher data rates via the spatial domain. For example, more than one active UE panel may be used (and/or considered) at a given time (e.g., a UE may use multiple active UE panels for uplink transmissions at a given time). Alternatively and/or additionally, services with reliability and latency may also be improved by parallel (e.g., simultaneous) uplink transmissions via different UE panels (e.g., more stringent reliability and/or latency requirements may be met by simultaneous uplink transmissions via different UE panels). The time-frequency resources for parallel (e.g., simultaneous) transmission via multiple panels may be the same time-frequency resources. Alternatively and/or additionally, the time-frequency resources for parallel (e.g., simultaneous) transmission via multiple panels may have at least partially overlapping time resources and/or at least partially overlapping frequency resources (e.g., where the time-frequency resources for transmission via a first panel at least partially overlap in the time or frequency domain with the time-frequency resources for transmission via a second panel).
The first problem may be that when there are two Physical Uplink Shared Channels (PUSCHs) transmitted to two TRPs via two different panels of the UE in parallel (e.g., simultaneously), the UE may have these two candidate PUSCHs for transmitting multiplexed Uplink Control Information (UCI), and thus, if there is no further design of UCI multiplexing, the network node may need to blindly decode these two PUSCHs. In some examples, the two TRPs may be in one serving cell. In some examples, one of the two TRPs is in a serving cell, and the other of the two TRPs may be in a neighboring serving cell (e.g., associated with a serving cell). In some examples, the neighboring cell may have a different Physical Cell Identity (PCI) than the serving cell. In some examples, the two TRPs are associated with different coresetpoil indices (e.g., one of the two TRPs is associated with one coresetpoil index and the other of the two TRPs may be associated with the other coresetpoil index). Alternatively and/or additionally, the TRP may be associated with a different index (e.g., a particular index) associated with the TRP and/or coresetpoolndex. In some examples, the neighboring cells may have an additionpci/additionpci index. In this disclosure, the term "additionpci/additionpci index" may refer to additionpci (e.g., extra PCI) and/or additionpci index (e.g., extra PCI index). In some examples, the two PUSCHs transmitted to the two TRPs may be scheduled by a single Downlink Control Information (DCI) (e.g., a single DCI scheduling multiple transmission and/or reception points (mTRP)). In some examples, the two PUSCHs transmitted to the two TRPs may be scheduled by respective DCIs (e.g., multiple DCIs scheduling mTRP).
In some examples, when the UE is to transmit one or more PUSCHs and/or one or more Physical Uplink Control Channels (PUCCHs) that at least partially overlap each other in the time domain, the UE may multiplex UCI (e.g., carried on the PUCCH) into the PUSCH (e.g., the UE may multiplex UCI into the PUSCH in a scenario in which the PUSCH and PUCCH have the same priority index). In some examples, UCI multiplexing may be applied on PUSCH that starts earlier (e.g., in the overlapping PUSCH) and/or in a serving cell with the smallest serving cell index (e.g., among one or more serving cells) when there are multiple serving cells with overlapping PUSCH. However, if there are two PUSCHs with the same starting symbol on the serving cell, it may be ambiguous and/or further design may be required whether UCI multiplexing is allowed on this serving cell.
In some examples, how the UE may perform UCI multiplexing may require further design in some scenarios, such as when the UE transmits (i) two PUCCHs on a first serving cell that are associated with different priority indices (e.g., priority index for one pucch=0 or 1) and (ii) two PUSCHs on a second serving cell that are associated with different priority indices (e.g., priority index for one pusch=0 or 1). In some examples, two PUCCHs in a first serving cell are transmitted in parallel (e.g., simultaneously) to two TRPs via two different panels of a UE. In some examples, two PUSCHs in the second serving cell are transmitted in parallel (e.g., simultaneously) to the two TRPs via two different panels of the UE. In some examples, if one of the first or second serving cells does not support mTRP transmissions or parallel (e.g., simultaneous) uplink transmissions (e.g., there is only one PUCCH or one PUSCH), how to multiplex UCI with the other serving cell with the supported mTRP transmissions or parallel (e.g., simultaneous) uplink transmission treatments.
A second problem may be enhancement on parallel (e.g., simultaneous) PUSCH and PUCCH transmissions. For the same priority index of PUSCH and PUCCH, the UE may multiplex them, transmit the multiplexed UCI on PUSCH, and/or discard unused/untransmitted/de-prioritized PUCCHs. However, multiplexing UCI of a first TRP on PUSCH towards a second TRP may cause some problems, as UCI may be associated with one TRP instead of another. For example, additional exchange time between TRPs may need to be at the network node side, and if the first and second TRPs are associated with different uplink timing (e.g., if the first and second TRPs are associated with different timing advances and/or different time alignments), then whether/how to multiplex UCI may also need further design. Whether parallel (e.g., simultaneous) uplink transmissions with different priority indices are allowed may also require design for the different priority indices.
A third problem may be associated with a consistent understanding of how a UE and a network node have which scheme to use for uplink transmission when the UE supports parallel (e.g., simultaneous) uplink transmission (e.g., via mTRP). In some examples, whether one or more uplink transmissions are associated with a single TRP uplink transmission or mTRP uplink transmission. For example, when the network node provides configuration of PUCCH/PUSCH, the UE knows how to operate in a single TRP uplink transmission, TDM for mTRP uplink transmission, frequency Domain Multiplexing (FDM) for mTRP uplink transmission, and/or Spatial Domain Multiplexing (SDM) for mTRP uplink transmission.
A fourth problem may be associated with how to define a hybrid automatic repeat request (HARQ) feedback scheme for mTRP downlink reception and parallel (e.g., simultaneous) uplink transmission. Since legacy NRs do not support parallel (e.g., simultaneous) uplink transmission in one serving cell, a UE may multiplex two sub-codebooks (i.e., joint HARQ feedback) respectively associated with different TRPs, or may transmit TDM PUCCH (i.e., separate HARQ feedback) associated with different TRPs in one slot or different slots, regardless of joint or separate HARQ feedback (scheme) (e.g., configured) for the UE. However, when the UE is configured with parallel (e.g., simultaneous) uplink transmissions, further discussion may be required as to whether the separate HARQ feedback scheme is still applicable.
A first concept of the present disclosure may be that UCI multiplexing may not be allowed to be considered/used/determined/derived for a first serving cell (e.g., UCI multiplexing may not be allowed to be considered/used/determined/derived for two parallel uplink transmissions/channels) when a UE is scheduled or configured to transmit two parallel (e.g., simultaneous) uplink transmissions/channels (e.g., with the same starting symbol) on the first serving cell. In this disclosure, the term "consider/use/determine/derive" may refer to consider, use, determine and/or derive. In some examples, two parallel uplink transmissions/channels on the first serving cell are not allowed to multiplex UCI. In some examples, UCI multiplexing is not allowed in a time slot with two parallel uplink transmissions/channels (with the same starting symbol) on the first serving cell. Alternatively and/or additionally UCI multiplexing may be allowed on this serving cell, but in a time slot without parallel uplink transmission/channels or in a time slot with different starting symbols of the two parallel uplink transmission/channels on the first serving cell. In some examples, a time slot without a parallel uplink transmission/channel may correspond to a time slot that does not contain multiple uplink transmissions with the same starting symbol on the first serving cell. In some examples, a slot without parallel uplink transmission/channel may be a slot with a single TRP uplink transmission (e.g., no repetition in one slot and/or no FDM, SDM repetition in one slot). In some examples, the limitation in the network node is that the network node needs to schedule different start symbols for two parallel uplink transmissions/channels, and preferably the two parallel uplink transmissions/channels are associated with respective first or second indices (e.g., coresetpoirindex = 0/1, or first/second group index).
Alternatively and/or additionally, the first concept may be that the UE determines (e.g., selects) one of two parallel uplink transmissions/channels on the first serving cell for UCI multiplexing when the UE is scheduled or configured to transmit the two parallel uplink transmissions/channels (with the same starting symbol) on the first serving cell. In some examples, the UE determines (e.g., selects) one of two parallel uplink transmissions/channels on the first serving cell for UCI multiplexing based on a lower (TRP/TRP group) index or a lower coresetpoindex (selecting one of the two parallel uplink transmissions/channels associated therewith). In some examples, for two parallel uplink transmissions/channels on an inter-cell mTRP (one uplink transmission on a first serving cell and another uplink transmission on a second cell with an additional pci index or additional pci), the UE determines (e.g., selects) one of the two parallel uplink transmissions/channels on the first serving cell for UCI multiplexing based on the first serving cell as a serving cell (but not the non-serving cell or the second cell with an additional pci index or additional pci). In some examples, the UE determines (e.g., selects) one of the two parallel uplink transmissions/channels on the first serving cell for UCI multiplexing based on which of the two parallel uplink transmissions/channels is associated with an Uplink (UL) Transmission Configuration Indicator (TCI) state associated with the serving cell. In some examples, the UE determines (e.g., selects) one of the two parallel uplink transmissions/channels on the first serving cell for UCI multiplexing based on which of the two parallel uplink transmissions/channels is associated with the UL TCI state associated with the lower additional pci index or additional pci. In some examples, the UE may be configured with which of the two parallel uplink transmissions/channels to multiplex the UCI on (when the UE determines that the first serving cell is for multiplexing UCI). In some examples, the DCI may provide information whether one or two transmissions/channels are allowed for UCI multiplexing for two parallel uplink transmissions/channels associated with/scheduled by the DCI. In some examples, radio Resource Control (RRC) signaling may provide information whether one or both transport/channels are allowed for UCI multiplexing for two parallel uplink transport/channels associated with/configured by RRC signaling. In some examples, one of the two parallel uplink transmissions/channels on the first serving cell for UCI multiplexing that is determined (e.g., selected) by the UE may be determined (e.g., derived) based on characteristics of each of the two parallel uplink transmissions/channels. In some examples, the characteristics of the transmission/channel may be configured grant PUSCH, dynamic grant PUSCH, msg3 PUSCH, msgA PUSCH, or semi-persistent PUSCH. In some examples, the characteristics of the transmission/channel may be aperiodic PUCCH, semi-persistent PUCCH, periodic PUCCH. In some examples, the UE does not determine (or select) one of the two parallel uplink transmissions/channels having one or more second characteristics (e.g., is msg3 or msgA PUSCH). In some examples, the UE may determine (e.g., select) one of two parallel uplink transmissions/channels having one or more first characteristics (e.g., being a Dynamic Grant (DG), a Configured Grant (CG), and/or a semi-persistent PUSCH). In some examples, when both parallel uplink transmissions/channels are associated with one or more first characteristics, the UE may determine (e.g., select) one of the two parallel uplink transmissions/channels associated with a dynamic grant PUSCH. Alternatively and/or additionally, when two parallel uplink transmissions/channels are associated with the one or more first characteristics, the UE may determine (e.g., select) one of the two parallel uplink transmissions/channels associated with the configured grant PUSCH. Alternatively and/or additionally, when both parallel uplink transmissions/channels are associated with the same characteristic, the UE may determine (e.g., select) one of the two parallel uplink transmissions/channels associated with a lower (TRP/TRP group) index. In some examples, the characteristic of the transport/channel may be a priority index of the transport/channel. In some examples, the UE may determine (e.g., select) one of the two parallel uplink transmissions/channels associated with the higher priority index. In some examples, when both parallel uplink transmissions/channels are associated with the same priority index, the UE may determine (e.g., select) one of the two parallel uplink transmissions/channels associated with a lower (TRP/TRP group) index. In some examples, examples of the present disclosure indicating that the first element with the lower index is determined may suggest: (i) The index of the first element is lower than the index of the second element, and/or (ii) the first element is selected (e.g., for UCI multiplexing) from two (or more) elements including the first element and the second element based on the index of the first element being lower than the index of the second element (and/or other elements of the two or more elements). For example, an indication that "the UE may determine one of the two parallel uplink transmissions/channels associated with a lower TRP/TRP group index" may imply: (i) The TRP/TRP group index of the one of the two parallel uplink transmissions/channels is lower than the TRP/TRP group index of the other of the two parallel uplink transmissions/channels, and/or (ii) the one of the two parallel uplink transmissions/channels is selected (e.g., for UCI multiplexing) from the two parallel uplink transmissions/channels based on the TRP/TRP group of the first element being lower than the index of the second element (and/or other elements of the two or more elements). In some examples, examples of the present disclosure indicating that a first element with a higher index is determined may suggest: (i) The index of the first element is higher than the index of the second element, and/or (ii) the first element is selected (e.g., for UCI multiplexing) from two (or more) elements including the first element and the second element based on the index of the first element being higher than the index of the second element (and/or other elements of the two or more elements). In some examples, each of the two parallel uplink transmissions/channels is associated with a respective/different TRP/TRP group index (e.g., coresetpoolndex). In some examples, the two parallel uplink transmissions/channels are associated with multi-DCI (mdis) based mTRP operation (or each of the two parallel uplink transmissions/channels is scheduled by a respective DCI or configured by a respective configured grant). In some examples, one of the two parallel uplink transmissions/channels on the first serving cell for UCI multiplexing that is determined (e.g., selected) by the UE may be determined (e.g., derived) based on the content of the UCI and/or characteristics associated with the UCI. In some examples, based on which associated TRP/TRP group of UCI (e.g., to be multiplexed), the UE may determine (e.g., select) one of the two parallel uplink transmissions/channels associated with the associated TRP/TRP group of UCI. In some examples, UCI multiplexing on a per TRP basis may be performed. In some examples, for UCI associated with a first TRP/TRP group (e.g., HARQ information or Scheduling Request (SR)), the UE may determine (e.g., select) one of the two parallel uplink transmissions/channels associated with the first TRP/TRP group. In some examples, for UCI (e.g., HARQ information or SR) associated with the second TRP/TRP group, the UE may determine (e.g., select) one of the two parallel uplink transmissions/channels associated with the second TRP/TRP group. In some examples, for UCI (e.g., HARQ information or SR) associated with both the first TRP/TRP group and the second TRP/TRP group, the UE may determine (e.g., select) one of the two parallel uplink transmissions/channels associated with a lower (TRP/TRP group) index. In some examples, UCI associated with the first TRP/TRP group (e.g., HARQ information) may mean or correspond to UCI being responsive to transmissions (scheduled by DCI or configured by RRC signaling) associated with the first TRP/TRP group. In some examples, UCI associated with the second TRP/TRP group (e.g., HARQ information) may mean or correspond to UCI being responsive to transmissions (scheduled by DCI or configured by RRC signaling) associated with the second TRP/TRP group.
Alternatively and/or additionally, when the UE is scheduled or configured to transmit two parallel uplink transmissions/channels (with the same starting symbol) on the first serving cell, the first concept may be that the UE may determine (e.g., select) the first serving cell for multiplexing UCI, and/or the UE may (and/or may be configured to) multiplex UCI on the two parallel uplink transmissions/channels. In some examples, UCI is repeated on two parallel uplink transmissions/channels. In some examples, UCI may include HARQ information associated with a first TRP for one serving cell (i.e., coresetpoolndex=0) and/or HARQ information associated with a second TRP for the same serving cell or a neighboring cell with an additionpci or extra PCI index (i.e., coresetpoolndex=1). In some examples, the UE multiplexes UCI on two parallel uplink transmissions/channels (with the same starting symbol) regardless of which TRP the UCI includes or the HARQ information for both TRPs. In some examples, for different starting symbols of two parallel uplink transmissions/channels (with partial overlap in the time domain on the first serving cell), the UE multiplexes UCI on the earlier starting (only) one of the two parallel uplink transmissions/channels. In some examples, the UE may transmit UCI on two parallel uplink transmissions/channels on the first serving cell for the same starting symbol of the two parallel uplink transmissions/channels on the first serving cell. In some examples, the UE may transmit UCI on two parallel uplink transmissions/channels for the same start symbol of two parallel uplink transmissions/channels, one on the first serving cell and the other on the second cell with an additionalPCIindex or additionalPCI. In some examples, for the same starting symbol of two parallel uplink transmissions/channels, one on a first serving cell and the other on a second (serving) cell without an additional pci or additional pci, the UE may transmit the two parallel uplink transmissions/channels and/or may transmit UCI on (only) one of the two parallel uplink transmissions/channels on the serving cell with the lower serving cell index. In some examples, when the UE multiplexes UCI on one or both of the two parallel uplink transmissions/channels, the UE may discard (original) one or more PUCCHs for UCI. In some examples, the UE may multiplex UCI (e.g., HARQ information or SRs) associated with both the first TRP/TRP group and the second TRP/TRP group into two parallel uplink transmissions/channels. In some examples, the UE may determine whether to multiplex UCI into two parallel uplink transmissions/channels based on whether single DCI (sdi) -based mTRP operations apply (to the two parallel uplink transmissions/channels). In some examples, the UE multiplexes UCI into two parallel uplink transmissions/channels when and/or if the two parallel uplink transmissions/channels are scheduled by a single DCI (e.g., with the same starting symbols for the two uplink transmissions/channels). In some examples, the UE may multiplex UCI into two parallel uplink transmissions/channels when the UE is not configured with a TRP/TRP group index or coresetpoolndex for the first serving cell. On the other hand, for mdis-based mTRP operation applications (to two parallel uplink transmissions/channels) the UE does not multiplex UCI on the two parallel uplink transmissions/channels. In some examples, the UE does not multiplex UCI on two parallel uplink transmissions/channels when the two parallel uplink transmissions/channels are scheduled by respective DCIs (rather than by a single DCI), or the two parallel uplink transmissions/channels are configured with TRP/TRP group indexes. In some examples, (for mdis-based mTRP operation) the UE multiplexes UCI on one of two parallel uplink transmissions/channels. In some examples, the UE multiplexes UCI on two parallel uplink transmissions/channels, regardless of/in either the sdi-based mTRP operation or the mdi-based mTRP operation. In some examples, the UE multiplexes UCI on one of two parallel uplink transmissions/channels, whether/not the sdi-based mTRP operation or the mdi-based mTRP operation.
In some examples, UCI0 corresponds to a first plurality of UCI associated with a first index (e.g., coresetpoirindex=0, or a first TRP group index). In some examples, UCI0 may also include UCI corresponding to a serving cell without being configured with coretpoolindex or mTRP operations for a Physical Downlink Shared Channel (PDSCH), a Physical Downlink Control Channel (PDCCH), PUSCH, and/or PUCCH.
In some examples, UCI1 corresponds to a second plurality of UCI associated with a second index (e.g., coresetpoolndex=1, or a second TRP group index).
In some examples, UCI for which TRP is to be multiplexed into the one or more uplink channels may be associated with one or more of the following: (i) UCI0 is multiplexed into PUCCH/PUSCH associated with the first index and UCI1 is multiplexed into PUCCH/PUSCH associated with the second index, (ii) UCI0 and UCI1 (e.g., UCI0+uci 1) are both multiplexed into one PUSCH/PUCCH that may be determined (e.g., selected) as above, and/or (iii) UCI0 and UCI1 (e.g., UCI0+uci 1) are both multiplexed into PUCCH/PUSCH associated with the first index and PUCCH/PUSCH associated with the second index (e.g., UCI is repeated on both channels).
In some examples, one of the two parallel uplink transmissions/channels may be PUCCH/PUSCH associated with a first index and the other of the two parallel uplink transmissions/channels may be PUCCH/PUSCH associated with a second index.
In some examples, two parallel uplink transmissions/channels are scheduled by a single DCI (e.g., a sdi-based mTRP).
In some examples, two parallel uplink transmissions/channels are scheduled by each DCI associated with a first index and a second index, respectively (e.g., mdis-based mTRP).
In some examples, two parallel uplink transmissions/channels are associated with or deliver the same Transport Block (TB).
In some examples, two parallel uplink transmissions/channels are associated with or deliver different TBs.
In some examples, the two parallel uplink transmissions/channels may be two channels (on the serving cell) that at least partially overlap in the time domain.
In some examples, the UE transmits one of the two parallel uplink transmissions/channels via a first joint/UL TCI state or spatial relationship and the other of the two parallel uplink transmissions/channels via a second joint/UL TCI state or spatial relationship.
In some examples, the first and second combined/UL TCI states are indicated by beam indication DCI.
In some examples, the first joint/UL TCI state is indicated by a first beam indication DCI.
In some examples, the first beam indication DCI is associated with a first index (e.g., coresetpoirindex=0, or a first group index).
In some examples, the second joint/UL TCI state is indicated by a second beam indication DCI.
In some examples, the second beam indication DCI is associated with a second index (e.g., coresetpoirindex=1, or a second group index).
In some examples, the first joint/UL TCI state is associated with a first set of Sounding Reference Signal (SRS) resources.
In some examples, for an uplink channel associated with the first set of SRS resources, the UE transmits the uplink channel based on the same precoder as one SRS in the first set of SRS resources. The one SRS resource may be indicated by DCI or configured by RRC signaling.
In some examples, for an uplink channel associated with the second set of SRS resources, the UE transmits the uplink channel based on the same precoder as one SRS in the second set of SRS resources. The one SRS resource may be indicated by DCI or configured by RRC signaling.
A second concept of the present disclosure may be that the UE may perform UCI multiplexing per TRP (or index associated with TRP). In some examples, UCI multiplexing timelines may also be applied per TRP. In some examples, there are multiple overlapping PUSCHs and PUCCHs including a first set of PUSCHs and/or PUCCHs and a second set of PUSCHs and/or PUCCHs. In one example, if the overlapping uplink channel is associated with an earliest starting symbol among the plurality of overlapping PUSCHs and PUCCHs and is associated with a first TRP, the UE does not consider the overlapping channel when the UE performs UCI multiplexing for a second TRP. Alternatively and/or additionally, when the UE determines to multiplex/collect one or more UCI for the second TRP from PUCCHs in the second set of PUCCHs, UCI in the overlapping channels is not considered for the one or more UCI. Alternatively and/or additionally, when the UE performs UCI multiplexing on the PUSCH for the second TRP, the UE determines (e.g., selects) a PUSCH for UCI multiplexing among PUSCHs associated with the second TRP.
Alternatively and/or additionally, the second concept may be that the UE multiplexes UCI (of the fifth PUCCH) on a time domain overlapping with the fifth PUSCH and transmits the fifth PUSCH in the first timing, and the UE transmits the sixth PUCCH including UCI and the sixth PUSCH in parallel in the second timing. In some examples, the UE supports parallel (e.g., simultaneous) PUCCH and PUSCH on different cells.
For the first timing, in some examples, the fifth PUSCH is in the first serving cell. In some examples, the fifth PUCCH is in a serving cell, which may be an in-band cell as the first serving cell. In some examples, the fifth PUCCH and the fifth PUSCH are associated with the same TRP/TRP group index. In some examples, the fifth PUSCH and the fifth PUCCH are associated with the same priority index. In some examples, the UE multiplexes UCI of the fifth PUCCH into the fifth PUSCH and/or transmits the fifth PUSCH and/or discards the fifth PUCCH based on the same TRP/TRP group index of the fifth PUSCH and the fifth PUCCH. In some examples, the fifth PUSCH may satisfy the UCI multiplexing timeline.
For the second timing, in some examples, the sixth PUSCH is in the first serving cell. In some examples, the sixth PUCCH is in a serving cell that is an inter-band cell different from the first serving cell. In some examples, the sixth PUCCH and the sixth PUSCH are associated with different TRP/TRP group indices. In some examples, the sixth PUSCH and the sixth PUCCH are associated with the same priority index. In some examples, the UE may transmit the sixth PUCCH and the sixth PUSCH in parallel based on different TRP/TRP group indexes of the sixth PUSCH and the sixth PUCCH.
In some examples, the UCI multiplexing timeline may be any of the following combined bullets:
the first timing threshold (e.g.,) Corresponding to the (required) time interval between PDSCH and PUCCH. />
A second timing threshold (e.g.,) Corresponding to the (required) time interval between PDCCH and PUCCH.
A third timing threshold (e.g.,) Corresponding to the (required) time interval between PDCCH and PUSCH without aperiodic Channel State Information (CSI) reporting.
A fourth timing threshold (e.g.,) Corresponding to the (required) time interval between PDCCH and PUSCH with aperiodic CSI reports.
The first/second/third/fourth threshold may correspond to a time interval between a last symbol of an earlier channel and a first/start symbol of a subsequent channel of the respective two channels for the first/second/third/fourth threshold.
In some examples, when the UE multiplexes UCI on the resulting/specific/determined channel, the resulting/specific/determined channel needs to meet the UCI multiplexing timeline. In some examples, if there is more than one candidate resulting/specific/determined channel that meets the UCI multiplexing timeline, the UE determines (e.g., selects) the resulting/specific/determined channel with the earliest starting symbol.
In some examples, for each TRP UCI multiplexing timeline, the one or more PUSCHs or PUCCHs that do not have (TRP) indices or indices associated with TRP or coresetpoinolindex correspond to TRP having a first coresetpoinolindex (e.g., coresetpoinolindex=0). In some examples, the one or more PUSCHs or PUCCHs may be in a serving cell that is not configured with coresetpoirindex or mTRP operations for PDCCH, PDSCH, PUSCH and/or PUCCH.
For example, in one slot/sub-slot, { uplink channels 1,2,3,4,5,6,7,8} overlap partially or completely in the time domain and are preferably associated with one or more serving cells. In this disclosure, the term "slot/sub-slot" may refer to a slot and/or sub-slot. In some examples, uplink channels 1, 3, 5, 7 are associated with a first index associated with TRP or with a serving cell that is not configured with mTRP operation for PDCCH, PDSCH, PUSCH and/or PUCCH. In some examples, uplink channels 2, 4, 6, 8 are associated with a second index associated with TRP. In some examples, the starting symbols of uplink channels {1,2,3,4,5,6,7,8} are based on a non-strict ascending order, and/or the starting symbol of uplink channel i is the same as or earlier than the starting symbol of uplink channel i+1, where i=1-7. In some examples, the end symbol of each uplink channel is in the same slot/sub-slot. In some examples, for uplink channels 1, 3, 5, 7, the ue may determine (e.g., select) a first resulting/specific/determined channel for UCI multiplexing, and/or uplink channel 1 may be determined (e.g., selected) as the first resulting/specific/determined channel. In some examples, the first resulting/specific/determined channel is used to multiplex UCI in uplink channels 1, 3, 5, 7. In some examples, for uplink channels 2, 4, 6, 8, the ue may determine (e.g., select) a second resulting/particular/determined channel for UCI multiplexing, and/or uplink channel 2 may be determined (e.g., selected) as the second resulting/particular/determined channel. In some examples, the second resulting/specific/determined channel is used to multiplex UCI in uplink channels 2, 4, 6, 8 (even though uplink channel 1 with an earlier starting symbol satisfies UCI multiplexing for 8 uplink channels).
In some examples, the first set of PUSCHs and/or PUCCHs is associated with a first set of serving cells. In some examples, the second set of PUSCHs and/or PUCCHs is associated with a second set of serving cells. In some examples, the UE may multiplex UCI from PUCCHs in the first set of PUSCHs and/or PUCCHs into the first PUSCH. In some examples, the first PUSCH is in a first serving cell with a lowest serving cell index among the first set of serving cells. In some examples, the first serving cell may not have the lowest serving cell index among the serving cells for the plurality of overlapping PUSCHs and PUCCHs. In some examples, the UE may multiplex UCI from PUCCHs in the second set of PUSCHs and/or PUCCHs into the second PUSCH. In some examples, the second PUSCH is in a second serving cell with a lowest serving cell among the second set of serving cells. In some examples, the second serving cell may not have the lowest serving cell index among the serving cells for the plurality of overlapping PUSCHs and PUCCHs. In some examples, the first PUSCH may overlap with the second PUSCH in the time domain. In some examples, the first PUSCH and the second PUSCH may be in the same serving cell or in different cells. In some examples, the first PUSCH and the second PUSCH may be in an inter-band cell or an intra-band cell. In some examples, the first PUSCH may be associated with the same or different priority index as the second PUSCH. In some examples, the first PUSCH may have an earliest starting symbol among the first set of PUSCHs and/or PUCCHs.
In some examples, the first set of PUSCHs and/or PUCCHs is associated with a first coresetpoolndex. In some examples, the second set of PUSCHs and/or PUCCHs is associated with a second coresetpoolndex. In some examples, the first set of PUSCHs and/or PUCCHs are associated with one or more serving cells configured with a single TRP (or not configured with mTRP or not configured with coresetpoolndex) or with one or more serving cells including a respective first TRP associated with a first coresetpoolndex. In some examples, the second set of PUSCHs and/or PUCCHs are associated with another one or more serving cells including respective second TRPs associated with a second coresetpoolndex.
In some examples, the UE determines whether to perform UCI multiplexing on a per TRP basis based on the number of joint/Downlink (DL)/UL TCI states in the beam indication DCI. In this disclosure, the term "joint/DL/UL" may refer to joint, DL, and/or UL.
In some examples, when the beam indication DCI indicates one joint/UL TCI state, the UE does not perform UCI multiplexing on a per TRP basis or the UE performs UCI multiplexing among all overlapping uplink channels.
In some examples, when the beam indication DCI indicates two joint/UL TCI states, the UE may perform UCI multiplexing on a per TRP basis.
In some examples, the UE does not perform UCI multiplexing on a per TRP basis or performs UCI multiplexing among all overlapping uplink channels regardless of the number of joint/UL TCI states indicated by the beam indication DCI.
In some examples, the UE may perform UCI multiplexing on a per TRP basis regardless of the number of joint/UL TCI states indicated by the beam indication DCI.
In some examples, for a first TRP or TRP associated with a first index (e.g., coresetpoolndex or TRP group index), the UE may receive a first beam indication DCI indicating a joint/DL/ULTCI status for the first TRP. In some examples, the link may be considered to operate as a single TRP relative to a link between the first TRP and the UE.
In some examples, for a second TRP or TRP associated with a second index (e.g., coresetpoolndex or TRP group index), the UE may receive a second beam indication DCI indicating a joint/DL/UL TCI status for the second TRP. In some examples, the link may be considered to operate as a single TRP relative to a link between the second TRP and the UE.
In some examples, the first serving cell may include TRP1 and TRP2, where TRP1 is associated with a first index (e.g., coresetpoolndex or TRP group index) and TRP2 is associated with a second index (e.g., coresetpoolndex or TRP group index).
In some examples, the second serving cell may include TRP3 and TRP4, where TRP3 is associated with a first index (e.g., coresetpoolndex or TRP group index) and TRP4 is associated with a second index (e.g., coresetpoolndex or TRP group index).
In some examples, the third serving cell may include TRP5, where TRP5 is associated with the first index (e.g., coresetpoolndex or TRP group index).
In some examples, the fourth cell may include TRP6, where the fourth cell may be a neighboring cell or a non-serving cell or a cell with an additionalapci or additionalalicindex, and TRP6 is associated with a second index (e.g., coresetpoil index or TRP group index).
In some examples, the fourth cell is associated with a third serving cell.
In some examples, a TRP among the first/second/third serving cell and the fourth cell and associated (TRP) with the first index (if present) may be considered a first group of TRPs.
In some examples, a TRP among the first/second/third serving cell and the fourth cell and associated with the second index (if present) may be considered a second group of TRPs.
In some examples, after UCI multiplexing for the first coresetpoolndex or the first (TRP) index, the UE may perform one or more of the following: (i) the UE may transmit PUCCH1 on the first serving cell and PUSCH1 on the third serving cell, wherein the priority indices of PUCCH1 and PUSCH1 are different, and preferably the UE supports inter-band parallel (e.g. simultaneous) transmission of PUCCH and PUSCH, (ii) the UE may transmit PUCCH1 or PUSCH1 associated with a higher priority index, (iii) the UE may discard PUCCH1 or PUSCH1 associated with a lower priority index, and/or (iv) the UE may multiplex UCI of PUCCH1 on PUSCH1 and preferably discard PUCCH1, wherein PUCCH1 and PUSCH1 are associated with the same priority index or preferably with different priority indices.
In some examples, PUCCH1 and PUSCH1 may be in different serving cells.
In some examples, PUCCH1 and PUSCH1 are associated with inter-band cells.
In some examples, PUCCH1 and PUSCH1 are associated with a first set of PUSCHs and/or PUCCHs.

In some examples, PUSCH1 is associated with a first coresetpoolndex or a first (TRP) index.
In some examples, after UCI multiplexing for the second coresetpoolndex or the second (TRP) index, the UE may perform one or more of the following: (i) the UE may transmit PUCCH2 on the second serving cell and PUSCH2 on the fourth serving cell, wherein the priority indices of PUCCH2 and PUSCH2 are different, and preferably the UE supports inter-band parallel (e.g. simultaneous) transmission of PUCCH and PUSCH, (ii) the UE may transmit PUCCH2 or PUSCH2 associated with a higher priority index, (iii) the UE may discard PUCCH2 or PUSCH2 associated with a lower priority index, and/or (iv) the UE may multiplex UCI of PUCCH2 on PUSCH2 and preferably discard PUCCH2, wherein PUCCH2 and PUSCH2 are associated with the same priority index or preferably with different priority indices.
In some examples, PUCCH2 and PUSCH2 may be in different serving cells.
In some examples, PUCCH2 and PUSCH2 are associated with inter-band cells.
In some examples, PUCCH2 and PUSCH2 are associated with a second set of PUSCH and/or PUCCH.

In some examples, PUSCH1 and/or PUSCH2 may be associated with configured grant PUSCH.
In some examples, PUSCH1 and PUSCH2 may be associated with the same CG index or different CG indexes.
In some examples, PUSCH1 may be scheduled by a first DCI, and PUSCH2 and PUSCH3 may be scheduled by a second DCI.
In some examples, PUSCH1 and PUSCH2 are associated with the same HARQ process number.
In some examples, the UE may transmit PUSCH1, PUSCH2, PUCCH1, and PUCCH2 in parallel (e.g., simultaneously).
In some examples, the same priority index control channel and shared channel are not allowed to be transmitted on inter-band cells or preferably on intra-band cells for the same (TRP/TRP group) index or CORESETPoolIndex, UE, and/or the UE may multiplex UCI of PUCCH into PUSCH. In some examples, the same priority index control channel and shared channel may be transmitted on an inter-band cell or preferably on an in-band cell for different (TRP) indexes or CORESETPoolIndex, UE.
In some examples, when the UE supports parallel (e.g., simultaneous) transmission of inter-band PUSCH and PUCCH and when the UE performs mTRP transmission (i.e., sdi mTRP or mdi mTRP), the UE may transmit PUCCH1 in the first serving cell and PUSCH2 in the fourth serving cell, where PUCCH1 is associated with the same priority index as PUSCH2. In some examples, the first serving cell and the fourth cell are in different frequency bands. In some examples, the UE does not multiplex UCI on PUCCH1 into PUSCH2. In some examples, the UE may transmit PUCCH1 and PUSCH2 in parallel (e.g., simultaneously).
In some examples, when the UE supports parallel (e.g., simultaneous) transmission of inter-band PUSCH and PUCCH and when the UE performs mTRP transmission (i.e., sdi mTRP or mdi mTRP), the UE may transmit PUCCH2 in the second serving cell and PUSCH1 in the third serving cell, where PUCCH2 is associated with the same priority index as PUSCH1. In some examples, the UE does not multiplex UCI on PUCCH2 into PUSCH1. In some examples, the UE may transmit PUCCH2 and PUSCH1 in parallel (e.g., simultaneously).

A third concept of the present disclosure may be that the UE may receive a signal for providing information of which scheme is used for PUCCH transmission. The candidate/possible PUCCH schemes may be a single TRP without repetition, a single TRP with repetition, an intra-slot TDM mTRP PUCCH, an inter-slot TDM mTRP PUCCH, an FDM mTRP PUCCH, and/or an SDM mTRP PUCCH. The signal may be DCI, a Medium Access Control (MAC) Control Element (CE) or RRC signaling. In some examples, the signal may be a configuration for PUCCH resources, a configuration for PUCCH format, a configuration for PUCCH resource set, a configuration for PUCCH, a configuration for UL bandwidth part (BWP), a configuration for one serving cell, a configuration for one or more serving cells, or a configuration for a cell group or PUCCH group. In some examples, the signal may be scheduling DCI with or without a downlink assignment. In some examples, the signal may be scheduling DCI with or without an uplink assignment.
In some examples, the UE may switch/change the scheme for PUCCH transmission based at least on the signal. In some examples, the signal may be the same as beam indication signaling (e.g., beam indication DCI, which is a DL DCI format with a TCI field indicating a TCI code point from a MAC CE including joint or DL or ULTCI status).
In some examples, the UE may dynamically switch between having a single TRP that is repeated and the FDM/SDM mTRP PUCCH. In this disclosure, the term "FDM/SDM" may refer to FDM and/or SDM.
In some examples, the UE may dynamically switch between a single TRP without repetition and FDM/SDM mTRP PUCCH.
In some examples, the UE may dynamically switch between a single TRP with repetition and a TDM mTRP PUCCH.
In some examples, the UE may dynamically switch between a single TRP without repetition and the TDM mTRP PUCCH.
In some examples, the UE is configured with one of FDM, SDM, or TDM for mTRP PUCCH.
In some examples, even when the beam indication DCI indicates a TCI code point having two joint/UL TCI states, the signal may indicate whether the first or second joint/UL TCI states are used (i.e., the signal may dynamically indicate a switch between mTRP operation and single TRP operation).
In some examples, the UE may perform mTRP PUCCH when the beam indication DCI indicates a TCI code point with two joint/UL TCI states or there are two active joint/UL TCI states. In some examples, the UE may perform a single TRP PUCCH when the beam indication DCI indicates a TCI code point with one joint/UL TCI state or there is one active joint/UL TCI state.
In some examples, TDM/FDM/SDM may be based on signaling. In other words, the UE may consider an FDM mTRP PUCCH with a pair of PUCCHs when signaling FDM. In some examples, one PUCCH of the pair of PUCCHs starts in one Physical Resource Block (PRB) index and the other PUCCH of the pair of PUCCHs starts in the other PRB index. In some examples, one PUCCH of the pair of PUCCHs is associated with one joint/UL TCI and the other PUCCH of the pair of PUCCHs is associated with the other joint/UL TCI.
In some examples, for FDM/SDM mTRP PUCCHs (and e.g., when the beam indication DCI indicates two joint/UL TCI states and/or there are two active joint/UL TCI states), the UE may ignore the configuration of the number of repeated slots (e.g., nrofslots, or PUCCH-repetition nrofslots) if/when the UE is (also) configured with a configuration of the number of repeated slots for one PUCCH. In some examples, for FDM/SDM mTRP PUCCHs (and e.g., when the beam indication DCI indicates one joint/UL TCI state and/or there is (e.g., only) one active joint/UL TCI state), the UE may apply a configuration of the number of repeated slots (e.g., nrofslots, or PUCCH-repetition nrofslots) if/when the UE is (also) configured with a configuration of the number of repeated slots for one PUCCH. In some examples, the UE may transmit PUCCH with repetition via the same UL TCI state or beam (if the beam indication DCI indicates one joint/UL TCI state).
In some examples, the configuration of PUCCH resources may include parameters (e.g., one parameter) to configure whether TDM, FDM, SDM mTRP PUCCH is configured. In some examples, the parameter (e.g., the one parameter) applies when the beam indication DCI indicates two joint/UL TCI states or there are two active joint/UL TCI states. In some examples, the parameter does not apply when the beam indication DCI indicates (e.g., only) one joint/UL TCI state or there is (e.g., only) one active joint/UL TCI state. In some examples, when the UE is configured with a TDM mTRP PUCCH (i.e., whether there is a slot or intra-slot mTRP PUCCH may be based on whether the UE is configured with a sub-slot), the UE may be configured with a number of duplicate slots. In this example, the consistent configuration may be that the UE may be configured with a number of duplicate slots when there is a configuration for the TDM mTRP PUCCH. In some examples, when a UE is configured with FDM or SDM (parallel uplink transmission on one serving cell), the UE is not expected to be configured with the number of duplicate slots. In some examples, the limitation that exists in the network node is that the network node is not allowed or the network node prevents or inhibits parallel configuration of FDM/SDM mTRP uplink operations (e.g., parallel uplink transmissions) with a repetition slot number/repetition number/PUSCH aggregation factor for the UE.
Alternatively and/or additionally, the UE may be configured with a repetition scheme and a number of repetition slots for one PUCCH resource in parallel (e.g., the configuration of the PUCCH resource may be replaced by any other configuration). In some examples, the UE may determine whether to apply the number of repeated slots for one PUCCH resource based on the number joint/UL TCI status (being used or activated or indicated by beam indicating DCI).
To enhance 3GPP specifications, e.g., 3GPP TS 38.331V17.0.0, for wireless communications according to some embodiments herein, enhancements 1-2 are provided herein. Enhancements 1-2 reflect implementations according to some embodiments herein and include modifications to various sections of the 3GPP specifications.

In some examples, T (indicated in addition 1) is associated with an inter-slot TDM mTRP PUCCH or an intra-slot TDM mTRP PUCCH.

enhancement 2 may be implemented in accordance with one or more embodiments of the present disclosure, such as one or more embodiments of the third concept. In enhancement 2, add 2 is made to the first chapter of 3GPP TS 38.331V17.0.0. In some examples, embodiments of the third concept may be implemented via addition 2 in enhancement 2.

In some examples, S (indicated in addition 2) is associated with an SDM mTRP PUCCH.
Enhancement 2:

in some examples, for FDM mTRP PUCCHs, the UE is (further) configured with an offset between the two FDM PUCCHs. In some examples, the offset may be configured per PUCCH resource. In some examples, the offset is a PRB between a pair of PUCCH resources. In some examples, the pair of PUCCH resources includes two PUCCH resources with different starting PRBs. In some examples, the FDM mTRP PUCCH may include the same PRB used for hopping. In some examples, for example, one PUCCH resource comprising X symbols in the time domain with hops may be the earlier X/2 symbols (with a top function or a bottom function) in a PRB (e.g., PRB index Y (Z)) and the later X/2 symbols (with a bottom function or a top function) in a PRB (e.g., PRB index W (Q)). In some examples, when considering FDM mTRP PUCCH, PUCCHi may be the earlier X/2 symbols (with a top function or a bottom function) in a PRB (e.g., PRB index Y (Z)) and the later X/2 symbols (with a bottom function or a top function) in a PRB (e.g., PRB index W (Q)), and PUCCHj may be the earlier X/2 symbols (with a top function or a bottom function) in a PRB (e.g., PRB index W (Q)) and the later X/2 symbols (with a bottom function or a top function) in a PRB (e.g., PRB index Y (Z)). Alternatively and/or in some examples, for a configuration of one PUCCH with hopping and with an offset, to determine a pair of FDM PUCCH resources, PUCCHi is the earlier X/2 symbols (with a top function or a bottom function) in a PRB (e.g., PRB index Y (Z)) and the later X/2 symbols (with a bottom function or a top function) in a PRB (e.g., PRB index W (Q)) and PUCCHj is (further) based on the offset. In some examples, the offset for a hop with a lower PRB index has an additive function (e.g., PRB index plus offset for one hop used to determine PUCCHj). In some examples, the offset for a hop with a higher PRB index has a decreasing function (e.g., PRB index minus the offset of another hop used to determine PUCCHj). In some examples, one possible configuration for FDM mTRP PUCCH may be that the UE is configured with PUCCH with hopping, where a first hop in a first half of one PUCCH resource in PRB Y (Q) and a second hop in a second half of the one PUCCH resource in PRB W (Q) are associated with a first joint/UL TCI state, and a first hop in a first half of another PUCCH resource in PRB W (Q) and a second hop in a second half of another PUCCH resource in PRB Y (Z) are associated with a second joint/UL TCI state.
In some examples, PUCCH may be replaced by PUSCH.
A fourth concept of the present disclosure may be (for the stdci-based mTRP) that the UE may transmit an Aperiodic (AP) CSI report on two parallel uplink transmissions/channels when the UE receives DCI scheduling two parallel uplink transmissions/channels (preferably with the same or different starting symbols) on a first serving cell and the DCI requests the (aperiodic) CSI report (e.g., the CSI request field is set to 1). In some examples, the UE transmits the AP CSI report on two parallel uplink transmissions/channels regardless of/without UCI other than the AP CSI report overlapping the two parallel uplink transmissions/channels in the time domain.
In some examples, whether there is an inter-slot/sub-slot repetition, the same/different starting symbols for two parallel uplink transmissions/channels, whether there is another UCI in addition to the AP CSI report, and/or the stdci/mdis-based mTRP may affect whether the UE transmits/multiplexes the AP CSI report on one or two transmission occasions. In this disclosure, the term "sdi/mdis" may refer to sdi and/or mdis. In some examples, the UE determines whether to transmit and/or multiplex the AP CSI report using one transmission occasion or whether to transmit and/or multiplex the AP CSI report using two transmission occasions based on: (i) whether there is an inter-slot/sub-slot repetition, (ii) whether two parallel uplink transmissions/channels have the same or different starting symbols, (iii) whether there is another UCI (e.g., available for transmission) other than AP CSI reporting, and/or (iv) a sdi/mdis based mTRP.
In some examples, one transmission occasion may correspond to one of two parallel uplink transmissions/channels. In some examples, the two transmission occasions may correspond to two parallel uplink transmissions/channels.
In some examples, the UE transmits the AP CSI report on the two parallel uplink transmissions/channels when the two parallel uplink transmissions/channels have different start symbols (e.g., in a time slot). Alternatively and/or additionally, when the two parallel uplink transmissions/channels have different start symbols (e.g. in a time slot), the UE transmits an AP CSI report on the (earlier started) one of the two parallel uplink transmissions/channels.
In some examples, when the two parallel uplink transmissions/channels have different start symbols (e.g., in a slot) and the UE may multiplex another UCI in addition to the AP CSI report, the UE transmits the AP CSI report on one of the two parallel uplink transmissions/channels (earlier-started) (e.g., multiplexed with the other UCI). Alternatively and/or additionally, when the two parallel uplink transmissions/channels have different starting symbols (e.g., in a slot) and the UE may multiplex another UCI in addition to the AP CSI report, the UE transmits the AP CSI report on the two parallel uplink transmissions/channels (e.g., multiplexes with the other UCI).
In some examples, when the two parallel uplink transmissions/channels have different starting symbols (e.g., in a slot) and there is another UCI overlapping the two parallel uplink transmissions/channels other than the AP CSI report, the UE transmits the AP CSI report (e.g., multiplexes with the other UCI) on the (earlier starting) one of the two parallel uplink transmissions/channels. Alternatively and/or additionally, when the two parallel uplink transmissions/channels have different starting symbols (e.g., in a slot) and there is another UCI overlapping the two parallel uplink transmissions/channels other than the AP CSI report, the UE transmits the AP CSI report on the two parallel uplink transmissions/channels (e.g., multiplexed with the other UCI).
In some examples, the UE transmits the AP CSI report on the two parallel uplink transmissions/channels when the two parallel uplink transmissions/channels have the same starting symbol (e.g., in a slot). Alternatively and/or additionally, the UE transmits the AP CSI report on one of the two parallel uplink transmissions/channels when the two parallel uplink transmissions/channels have the same starting symbol (e.g., in a slot).
In some examples, when the two parallel uplink transmissions/channels have the same starting symbol (e.g., in a slot) and the UE may multiplex another UCI in addition to the AP CSI report, the UE transmits the AP CSI report on one of the two parallel uplink transmissions/channels (e.g., multiplexes with the other UCI). Alternatively and/or additionally, when the two parallel uplink transmissions/channels have the same starting symbol (e.g., in a slot) and the UE may multiplex another UCI in addition to the AP CSI report, the UE transmits the AP CSI report on the two parallel uplink transmissions/channels (e.g., multiplexed with the other UCI).
In some examples, when the two parallel uplink transmissions/channels have the same starting symbol (e.g., in a slot) and there is another UCI overlapping the two parallel uplink transmissions/channels other than the AP CSI report, the UE transmits the AP CSI report on one of the two parallel uplink transmissions/channels (e.g., multiplexes with the other UCI). Alternatively and/or additionally, when the two parallel uplink transmissions/channels have the same starting symbol (e.g., in a slot) and there is another UCI overlapping the two parallel uplink transmissions/channels other than the AP CSI report, the UE transmits the AP CSI report on the two parallel uplink transmissions/channels (e.g., multiplexed with the other UCI).
In some examples, the one of the two parallel uplink transmissions/channels may be determined (e.g., derived) based on one or more of: (i) which uplink transmission/channel is associated with a first joint/UL TCI state, (ii) which uplink transmission/channel is associated with a joint/UL TCI state of a serving cell or no additional pci/additional pci index, (iii) which uplink transmission/channel is associated with a lower index (e.g., additional pci/additional pci index), (iv) which uplink transmission/channel is associated with a first SRS resource set (having a lower SRS resource set index than a second SRS resource set), and/or (v) which uplink transmission/channel starts earlier.
In some examples, the one of the two parallel uplink transmissions/channels may be determined (e.g., derived) based on one or more of: (i) which uplink transmission/channel is associated with the second combined/UL TCI state, (ii) which uplink transmission/channel is associated with the combined/UL TCI state associated with the neighboring serving cell or with the additionalapci/additionalalicardex, (iii) which uplink transmission/channel is associated with a higher index (e.g., additionalapci/additionalapci index), (iv) which uplink transmission/channel is associated with the second SRS resource set (e.g., with a higher SRS resource set index than the first SRS resource set), and/or (v) which uplink transmission/channel starts later.
In some examples, the number of duplicate slots configured by RRC signaling or indicated by DCI may be applied in parallel with two transmissions/channels (e.g., two parallel transmissions/channels) per slot/sub-slot. In some examples, the number of duplicate slots may be a PUSCH aggregation factor (e.g., semi-statically configured) or a number of repetitions (e.g., semi-statically configured and/or dynamically indicated). In some examples, each slot or sub-slot may have two transmission opportunities (e.g., with the same or different start symbols) when there are a number of duplicate slots applied in parallel with two transmissions/channels per slot/sub-slot (e.g., two parallel transmissions/channels).
In some examples, (e.g., when two parallel uplink transmissions/channels have the same/different starting symbols (in a slot)), the UE may multiplex and/or transmit the AP CSI report on the two parallel uplink transmissions/channels in the earliest slot/sub-slot. In some examples, the UE does not multiplex and/or transmit AP CSI reports for transmission opportunities in the remaining slots/sub-slots.
In some examples, the UE may multiplex and/or transmit the AP CSI report on a first channel of the two parallel uplink transmissions/channels in an earliest slot/sub-slot (e.g., when the two parallel uplink transmissions/channels have the same/different starting symbols (in the slot)), and the first channel may be associated with a first SRS resource set (having a lower SRS resource set index than the second SRS resource set). In some examples, the UE may multiplex and/or transmit the AP CSI report on a second channel of the two parallel uplink transmissions/channels in a second earliest slot/sub-slot (e.g., when the two parallel uplink transmissions/channels have different start symbols (in the slot), and the second channel may be associated with a second SRS resource set (e.g., having a higher SRS resource set index than the first SRS resource set). In some examples, the UE does not multiplex and/or transmit AP CSI reports for transmission opportunities in the remaining slots/sub-slots. In some examples, the UE does not multiplex and/or transmit the AP CSI report in the earliest slot/sub-slot in the second channel associated with the second SRS resource set. In some examples, the UE does not multiplex and/or transmit the AP CSI report in the first channel associated with the first SRS resource set in the second earliest slot/sub-slot.
In some examples, when there is another UCI other than the AP CSI report that overlaps with two parallel uplink transmissions/channels or the UE may multiplex another UCI other than the AP CSI report, the UE multiplexes or transmits the AP CSI report on one of the two parallel uplink transmissions/channels (e.g., multiplexes with the other UCI).
In some examples, the first and second SRS resource sets are configured for codebook-based PUSCH transmissions or non-codebook-based PUSCH transmissions.
In some examples, the another UCI may be in a second serving cell.
In some examples, for TDM repetition of uplink transmissions/channels, the AP CSI report may be multiplexed or transmitted on a first channel in an earliest time slot and a second channel in a second earliest time slot. In some examples, if there is another UCI than the AP CSI report that overlaps with two parallel uplink transmissions/channels or the UE may multiplex another UCI than the AP CSI report, the UE multiplexes or transmits the AP CSI report (e.g., multiplexes with another UCI) on a second channel that is in the earliest time slot and is associated with the second SRS resource set. In some examples, the first channel is associated with a first set of SRS resources.
Alternatively and/or additionally, the fourth concept may be (for mdis-based mTRP) when the UE receives a first DCI scheduling a first PUSCH and a second DCI scheduling a second PUSCH, and the first PUSCH and the second PUSCH are scheduled as two parallel uplink transmissions/channels (e.g., with the same or different starting symbols) on the first serving cell. In some examples, the first DCI is associated with a first index (e.g., coresetpoirindex=0, or a first group index). In some examples, the second DCI is associated with a second index (e.g., coresetpoirindex=1, or a second group index). In some examples, the UE may transmit at least a first AP CSI report on two parallel uplink transmissions/channels with at least one of the first and second DCI requesting (aperiodic) CSI reports (e.g., CSI request field set to 1). Alternatively and/or additionally, the UE may transmit at least a first AP CSI report on the respective PUSCH. In some examples, the UE transmits and/or multiplexes the first CSI report on the first or second PUSCH based on which DCI requests the CSI report.
In some examples, the sdi and mdis based MTRP may use the same AP CSI reporting method as described above.
A fifth concept of the present disclosure may be for a first type of UCI not associated with a first TRP/TRP group nor with a second TRP/TRP group, an alternative is for the UE to determine that the first type of UCI may be multiplexed into (any) PUSCH/PUCCH associated with the first TRP/TRP group or (any) PUSCH/PUCCH associated with the second TRP/TRP group. Alternatively and/or additionally, the UE determines that the first type of UCI is multiplexed into PUSCH/PUCCH associated with a first TRP/TRP group (e.g., a TRP/TRP group with a lower TRP/TRP group index). Alternatively and/or additionally, when the UE may transmit two parallel (e.g., simultaneous) PUSCHs in the first serving cell, the UE may multiplex UCI of the first type into the two parallel PUSCHs.
In some examples, for a second type of UCI associated with a first TRP/TRP group or with a second TRP/TRP group, one alternative is that the UE may multiplex the second type of UCI into the corresponding PUCCH/PUSCH relative to the same TRP/TRP group. In some examples, the UE multiplexes UCI of the second type into (any) PUSCH/PUCCH associated with the first TRP/TRP group or (any) PUSCH/PUCCH associated with the second TRP/TRP group. Alternatively and/or additionally, when the UE may transmit two parallel (e.g., simultaneous) PUSCHs in the first serving cell, the UE may multiplex UCI of the second type into the two parallel PUSCHs.
For example, when the UE may transmit two parallel (e.g., simultaneous) PUSCHs in the first serving cell, the UE may multiplex UCI of the first type into the two parallel PUSCHs. And the UE may multiplex a second type of UCI associated with the first TRP/TRP group into a first PUSCH (associated with the first TRP/TRP group) of the two parallel PUSCHs and a second type of UCI associated with the second TRP/TRP group into a second PUSCH (associated with the second TRP/TRP group) of the two parallel PUSCHs.
A sixth concept of the present disclosure may be (for mdis based mTRP operation), the UE may multiplex UCI of PUCCH associated with the first TRP/TRP group and UCI of PUCCH associated with the second TRP/TRP group into one and the same PUSCH. The PUCCH associated with the first TRP/TRP group and the PUCCH associated with the second TRP/TRP group are overlapping and/or the starting symbol of the PUCCH associated with the first TRP/TRP group and the starting symbol of the PUCCH associated with the second TRP/TRP group. Alternatively and/or additionally, the sixth concept may be (for mdis-based mTRP operation), the UE may multiplex UCI into two overlapping PUSCHs in the serving cell, where one of the two PUSCHs is associated with a first TRP/TRP group and the other of the two PUSCHs is associated with a second TRP/TRP group. In some examples, the two PUSCHs overlap the two PUCCHs in the time domain. Alternatively and/or additionally, when there is a respective PUSCH for each TRP/TRP group, the UE may multiplex UCI of the PUCCH associated with the first TRP/TRP group into one PUSCH associated with the first TRP/TRP group of the two PUSCHs. In some examples, when there is a respective PUSCH for each TRP/TRP group, the UE may multiplex UCI of the PUCCH associated with the second TRP/TRP group into one PUSCH associated with the second TRP/TRP group of the two PUSCHs. In one example, in the exemplary scenario 900 of fig. 9, TRPA and TRP1 are associated with a first TRP/TRP group and TRPB and TRP2 are associated with a second TRP/TRP group. In a first example, the UE may respectively multiplex UCI of PUCCH to TRPA into PUSCH to TRP1 and UCI of PUCCH to TRPB into PUSCH to TRP 2. In a second example, the UE may multiplex UCI to PUCCH of TRPA and UCI to PUCCH of TRPB into PUSCH to TRP1 or PUSCH to TRP 2. In a third example, the UE may multiplex UCI to PUCCH of TRPA and UCI to PUCCH of TRPB into both PUSCH to TRP1 and PUSCH to TRP 2.
Alternatively and/or additionally, the sixth concept may be (for mdis based mTRP operation), the UE is not allowed to multiplex UCI of PUCCH associated with the first TRP/TRP group and UCI of PUCCH associated with the second TRP/TRP group into one and the same PUSCH. In some examples, based on the same TRP/TRP group index between two UCI and the one PUSCH, the UE may determine whether to multiplex UCI associated with the first TRP/TRP group or UCI associated with the second TRP/TRP group into the one PUSCH. For example, in the exemplary scenario 800 of fig. 8, when cell 2 is not configured with TRP/TRP groups (indexes), the UE may determine that PUSCH to cell 2 is associated with the first TRP/TRP group (because the UE may be configured with TRP/TRP groups (indexes) in cell 1). The UE multiplexes UCI of PUCCH to TRPA only into PUSCH to cell 2 (if TRP is associated with the first TRP/TRP group). The UE may discard the PUCCH to TRPB or the PUCCH not transmitted to TRPB. The UE does not transmit PUCCH to TRPB of cell 1 and PUSCH to cell 2 in parallel. The UE discards the PUCCH to TRPA of cell 1 and/or the UE does not transmit the PUCCH to TRPA of cell 1 (because the UE has multiplexed UCI to PUCCH of TRPA into PUSCH of cell 2). For another example, when cell 2 is associated with mTRP operation or the UE is configured with TRP/TRP groups (indexes) in cell 2, PUSCH to cell 2 may be associated with the first/second TRP/TRP group indexes. In some examples, based on the first/second TRP/TRP group index to the PUSCH of cell 2, the UE may determine whether to multiplex UCI associated with the first TRP/TRP group or UCI associated with the second TRP/TRP group into the PUSCH of cell 2.
In some examples, the UE may multiplex UCI0 and UCI1 into PUSCH based on a joint HARQ feedback mode for mTRP (or a mode for a separate HARQ feedback scheme with parallel (e.g., simultaneous) transmissions) (e.g., acknackfeedbackmode= "joint"). In some examples, UCI0 and UCI1 are associated with different TRP/TRP groups. In some examples, when there is (e.g., only) one PUSCH overlapping with the PUCCH for UCI0 and the PUCCH for UCI1 in the time domain. In some examples, UCI0 and UCI1 may be concentrated based on the (ascending) order of the associated TRP/TRP group index.
In some examples, the UE is not allowed to multiplex UCI0 and UCI1 into PUSCH based on separate HARQ feedback modes for mTRP (or modes for separate HARQ feedback schemes with parallel (e.g., simultaneous) transmissions) (e.g., acknackfeedback mode= "alone" or "simultaneous with alone"). In some examples, UCI0 and UCI1 are associated with different TRP/TRP groups. In some examples, when there is (e.g., only) one PUSCH overlapping PUCCH for UCI0 and PUCCH for UCI1 in the time domain, the UE may multiplex UCI0 or UCI1 into the one PUSCH. In some examples, the UE may determine to multiplex UCI0 or UCI1 into the one PUSCH based on the same TRP index between the one PUSCH and UCI0/UCI 1. In some examples, if the one PUSCH is not configured with a TRP/TRP group index (e.g., coresetpoolndex), the UE may determine multiplexing UCI0 or UCI1 based on which SRS resource set index is associated with the one PUSCH. In some examples, if the one PUSCH is not configured with a TRP/TRP group index (e.g., coresetpoolndex), the UE may determine that the one PUSCH is associated with a first TRP/TRP group index (e.g., coresetpoolndex=0). In some examples, the UE may be configured with mTRP operation on one of the serving cells, or the UE may be configured with mdis-based mTRP operation, or the UE may be configured with TRP/TRP group index on one of the serving cells. In some examples, the one PUSCH is in a first serving cell different from a serving cell of the PUCCH for UCI0 and different from a serving cell of the PUCCH for UCI1. In some examples, the serving cell for the PUCCH of UCI0 may be the same or different from the serving cell for the PUCCH of UCI1. In some examples, the UE may transmit the one PUSCH and the PUCCH for UCI1 in parallel (e.g., simultaneously) and/or discard the PUCCH for UCI0 (when the UE multiplexes UCI0 into the one PUSCH). In some examples, the UE is not allowed to multiplex UCI belonging to different TRP/TRP group indices into the one PUSCH (based on separate HARQ feedback mode).
A seventh concept of the present disclosure may be that the UE may provide information associated with its capabilities as to whether two parallel (e.g., simultaneous) transmissions/channels (i.e., first feature) in the respective serving cell are supported and/or whether two parallel (e.g., simultaneous) transmissions/channels (i.e., second feature) in one same serving cell are supported and/or whether the two features (i.e., first feature and second feature) are supported (in parallel, e.g., simultaneously, and/or in the same Transmission Time Interval (TTI)/slot). In some examples, the UE supports a first feature for a given TTI (e.g., slot/sub-slot). In some examples, the UE supports the first feature when the number of channels in a given TTI in each of the respective cells for two parallel (e.g., simultaneous) transmissions/channels is one (i.e., one channel in the first cell and one channel in the second cell), the UE may transmit two parallel (e.g., simultaneous) transmissions/channels in the respective cells. In some examples, a UE may be configured with inter-slot or intra-slot TDM mTRP PUCCH/PUSCH in one serving cell. In some examples, for a given TTI, when the UE may transmit the first PUSCH in the first serving cell and the second PUCCH in the second serving cell, the UE may transmit the first PUSCH and the second PUCCH in parallel (e.g., simultaneously) (even if the first PUSCH or the second PUCCH is associated with mTRP operation as TDM mTRP PUSCH/PUCCH). In some examples, the first PUSCH may be a single TRP PUSCH, or the first serving cell is not configured with mTRP operation or TRP/TRP group index. In some examples, the second PUCCH may be a single TRP PUCCH, or the second serving cell is not configured with mTRP operation or TRP/TRP group index.
In some examples, when a UE faces the scenario of the exemplary scenario 900 of fig. 9 that does not support both features (in parallel, e.g., simultaneously, and/or in the same TTI/slot). In some examples, the two PUSCHs in fig. 5 may be DG PUSCH, CG PUSCH, or msg3/a PUSCH. In some examples, the two PUCCHs in fig. 5 may be semi-persistent configured PUCCHs (e.g., SRs, periodic CSI reports, and/or semi-persistent CSI reports). In some examples, the UE may perform UCI multiplexing per TRP/TRP group. In some examples, the UE may then transmit only to PUSCH of TRP1 and TRP2 of cell 2 after UCI multiplexing.
For example, when the UE does not support two features (e.g., concurrently, e.g., simultaneously, and/or in the same TTI/slot) and the situation occurs (e.g., concurrent transmission of PUCCH in the first serving cell and PUSCH in the second serving cell, and/or concurrent transmission of two PUCCHs in the first serving cell or two PUSCHs in the second serving cell), the UE may perform one or more of: (i) multiplexing UCI on PUCCH into PUSCH (and dropping PUCCH), (ii) multiplexing UCI on PUCCH into another PUCCH (and transmitting the other PUCCH and dropping the PUCCH), (iii) transmitting PUSCH (and dropping one PUCCH or two PUCCHs (UCI on)), (iv) transmitting PUCCH (and dropping one PUSCH or two PUSCHs), (v) transmitting one PUCCH and one PUSCH (and dropping the other PUCCH and/or the other PUSCH), and/or (vi) transmitting one PUCCH and one PUSCH (and dropping the other PUCCH and/or the other PUSCH).
In some examples, the transmitted PUCCH/PUSCH may be associated with a higher priority index (e.g., priority index=1).
Alternatively and/or additionally, the seventh concept may be that the network node is not allowed to configure two parallel (e.g. simultaneous) transmissions/channels (first feature) of two serving cells and two parallel (e.g. simultaneous) transmissions/channels (second feature) of one same serving cell for the UE in parallel. In some examples, in response to receiving the capabilities of the UE (supporting the first feature and the second feature), the network node is not allowed to configure the first feature and the second feature in parallel. In some examples, the network node may configure the first feature or the second feature for the UE. Briefly, in some examples, features of parallel (e.g., simultaneous) uplink transmissions via two panels and/or features of parallel (e.g., simultaneous) PUCCH and PUSCH on different cells may not be supported and/or configured simultaneously.
In some examples, the first feature may be inter-band parallel (e.g., simultaneous) transmission of PUCCH and PUSCH.
In some examples, the second feature may be mTRP operation, FDM, or SDM via two parallel (e.g., simultaneous) uplink transmissions of two UE panels (to different TRPs). In some examples, the same type of channel (e.g., pusch+pusch, or pucch+pucch) for two parallel (e.g., simultaneous) uplink transmissions is applied.
With respect to one or more embodiments herein, such as one or more of the techniques, apparatuses, concepts, methods, example scenarios, and/or alternatives described above, in some examples UCI multiplexing on PUSCH in one slot may be replaced by UCI multiplexing on PUSCH in one sub-slot. In some examples, a sub-slot may be 7 or 2 symbols in one slot. In some examples, a slot may include more than one sub-slot.
With respect to one or more embodiments herein, UCI may be HARQ information, SR, and/or CSI reports in some examples.
With respect to one or more embodiments herein, in some examples, UCI may be aperiodic, periodic, and/or semi-persistent.
With respect to one or more embodiments herein, in some examples, a UE is configured to separately transmit HARQ associated with different coresetpoolndexs or different TRPs. In some examples, the UE may need to transmit
With respect to one or more embodiments herein, in some examples, a UE is configured to multiplex HARQ associated with different coresetpoolndexs or different TRPs.
With respect to one or more embodiments herein, in some examples, a UE is capable of performing parallel (e.g., simultaneous) uplink transmissions via multiple UE panels (e.g., multiple separate and/or distinct UE panels). The UE may switch from a parallel (e.g., simultaneous) uplink transmission (e.g., a parallel uplink transmission via multiple UE panels) to a single uplink transmission (e.g., an uplink transmission via one multiple UE panel at a given time). Alternatively and/or additionally, the UE may switch from a single uplink transmission (e.g., a parallel uplink transmission via one multi-UE panel at a given time) to a parallel (e.g., simultaneous) uplink transmission (e.g., a parallel uplink transmission via multiple UE panels).
With respect to one or more embodiments herein, in some examples, in NR, physical Uplink Shared Channel (PUSCH) transmissions may be non-codebook (NCB) based or Codebook (CB) based. For CB-based PUSCH, a set of Sounding Reference Signal (SRS) resources for CB PUSCH may be configured to the UE (e.g., the UE may be configured with a set of SRS resources for CB PUSCH), and the network may determine uplink channel conditions and identify which UE beam is preferred (e.g., strong Reference Signal Received Power (RSRP) and/or less interference) based on measuring SRS in the SRS resource set. In some examples, the UE beam may be selected based on a determination that the UE beam has a strong RSRP (e.g., an RSRP above a threshold and/or other RSRP above one or more other UE beams) and/or less interference (e.g., less interference than a threshold and/or less interference than one or more other UE beams) (e.g., based on a determination to measure one or more SRS in the SRS resource set). The network may schedule CB PUSCH via DCI indicating transmission of a precoding matrix index (TPMI) (e.g., for indicating UE-side precoding) and SRS Resource Indicator (SRI) (e.g., for indicating which beam and/or power related control is to be used).
With respect to one or more embodiments herein, in some examples, the set of SRS resources for the NCB PUSCH may be configured to the UE (e.g., the UE may be configured with the set of SRS resources for the NCB PUSCH) and the network may determine uplink channel conditions and identify which UE beam is preferred (e.g., strong RSRP and/or less interference) based on a Channel State Information (CSI) report of the UE (e.g., a CSI report associated with the UE, such as a CSI report transmitted by the UE). In some examples, the UE beam may be selected based on a determination that the UE beam has a strong RSRP (e.g., an RSRP above a threshold and/or other RSRP above one or more other UE beams) and/or less interference (e.g., less interference than a threshold and/or less interference than one or more other UE beams) (e.g., a determination based on CSI reporting of the UE). The NCB-based PUSCH may be based on downlink/uplink (DL/UL) channel reciprocity. The network may schedule the NCB PUSCH via DCI indicating the SRI (e.g., to indicate which beam and power related control is to be used). The UE may determine which precoding to use based on channel state information-based reference signals (CSI-RS) associated with the SRI.
With respect to one or more embodiments herein, in some examples, a UE may communicate with a plurality of TRPs including a first TRP and a second TRP. Fig. 5 illustrates a scenario 500 in which a UE (shown with reference numeral 550) communicates with a first TRP (shown with reference numeral 502) and a second TRP (shown with reference numeral 504) in a serving cell 506 (e.g., a single serving cell). For example, in scenario 500, both the first TRP 502 and the second TRP 504 may be in the serving cell 506.
Fig. 6 illustrates a scenario 600 in which a UE 550 communicates with a first TRP 502 and a second TRP 504, where the first TRP 502 is in a serving cell 506 and the second TRP 504 is in a cell 602, e.g., a non serving cell and/or a neighboring cell. For example, not both the first TRP 502 and the second TRP 504 are in the serving cell 506 (e.g., shown in scenario 500 of fig. 5), in scenario 600 the first TRP 502 and the second TRP 504 may be in different cells.
In some examples, for example, in scenario 500 shown in fig. 5 and in scenario 600 shown in fig. 6, UE 550 may communicate with first TRP 502 via first UE panel 512A and/or UE 550 may communicate with second TRP 504 via second UE panel 512B. In some examples, communication between the first TRP 502 and the UE 550 may be via the first beam/spatial filter/spatial relationship/spatial information/spatial relationship information 514. In this disclosure, the term "beam/spatial filter/spatial relationship/spatial information/spatial relationship information" may correspond to a beam, a spatial filter, a spatial relationship, spatial information, and/or spatial relationship information. In some examples, communication between the second TRP 504 and the UE 550 may be via a second beam/spatial filter/spatial relationship/spatial information/spatial relationship information 510.
In some examples, for example, in scenario 500 shown in fig. 5 and scenario 600 shown in fig. 6, the UE may perform (e.g., transmit) a first uplink transmission (e.g., the first uplink transmission may be transmitted to the first TRP 502) via the first beam/spatial filter/spatial relationship/spatial information/spatial relationship information 514. In some examples, the UE may perform (e.g., transmit) a second uplink transmission (e.g., the second uplink transmission may be transmitted to the second TRP 504) via the second beam/spatial filter/spatial relationship/spatial information/spatial relationship information 510. The first uplink transmission and the second uplink transmission may be performed in parallel (e.g., simultaneously) (e.g., transmitted by the UE). Fig. 7 shows a timing diagram of an exemplary scenario 700 associated with a UE transmitting to PUCCH 702 of cell 1, PUSCH 704 to TRP1 of cell 2, and/or PUSCH 706 to TRP2 of cell 2, wherein the three channels overlap (e.g., at least partially overlap) in the time domain. In some examples, the starting symbol of PUSCH 704 to TRP1 of cell 2 and the starting symbol of PUSCH 706 to TRP2 of cell 2 may be different (as shown in the exemplary scenario 700 of fig. 7) or the same. In some examples, the UE may transmit to PUSCH 704 of TRP1 of cell 2 via the first joint/UL TCI state and/or the first spatial relationship. In some examples, the UE may transmit to PUSCH 706 of TRP2 of cell 2 via the second combined/UL TCI state and/or the second spatial relationship. In some examples, the UE may transmit to PUCCH 702 of cell 1 via a third combined/UL TCI state and/or a third spatial relationship. In some examples, the UE may receive a first beam indicating DCI for cell 2 and a second beam indicating DCI for cell 1 (e.g., because cell 1 and cell 2 are inter-band cells). In some examples, the three channels are (at least) in the same time slot/sub-time slot.
In some examples, when the starting symbols of the two PUSCHs 704 and 706 are the same (e.g., the two PUSCHs 704 and 706 start at the same starting symbol) and the UE multiplexes UCI on PUCCH 702 into PUSCH on cell 2, the UE may multiplex UCI on the two PUSCHs (e.g., the UE may multiplex UCI into PUSCH 704 and may multiplex UCI into PUSCH 706). Alternatively and/or additionally, the UE may multiplex UCI on one of the two PUSCHs 704 and 706. For example, the UE may multiplex UCI into a PUSCH of the two PUSCHs 704 and 706 having a lower index (e.g., CORESETPoolIndex, TRP group index, SRS resource set index) than the other PUSCH of the two PUSCHs 704 and 706 (e.g., if PUSCH 704 has a lower index than PUSCH 706, the UE may multiplex UCI into PUSCH 704 and/or may not multiplex UCI into PUSCH 706). In some examples, when the UE multiplexes UCI on PUSCH (e.g., PUSCH 704 and/or PUSCH 706), the UE discards PUCCH 702 to cell 1.
In some examples, for per-TRP UCI multiplexing, UCI on PUCCH 702 to cell 1 may be determined to be associated with the first index when PUCCH 702 to cell 1 is not configured with an index associated with a TRP (e.g., when PUCCH 702 to cell 1 is not configured with an index associated with a TRP and/or when a UE is not configured with an index associated with a TRP associated with PUCCH 702). In some examples, the UE may determine (e.g., select) PUSCH 704 to TRP1 or PUSCH 706 to TRP2 for multiplexing UCI. In some examples, the UE multiplexes UCI into the determined PUSCH based on which PUSCH is associated with the first index. In an example where PUSCH 704 to TRP1 is associated with a first index, even though PUSCH 706 to TRP2 is earlier than PUSCH 704 to TRP1, since PUSCH 704 to TRP1 is associated with a first index (while PUSCH 706 to TRP2 is associated with a second index different from the first index, for example), the UE may multiplex UCI on PUSCH 704 to TRP 1. In some examples, both PUSCHs (e.g., PUSCH 704 and PUSCH 706) satisfy the UCI multiplexing timeline. In some examples, when the UE multiplexes UCI on PUSCH (e.g., PUSCH 704 and/or PUSCH 706), the UE discards PUCCH 702 to cell 1.
In some examples, considering priority index aspects, if the priority index of PUSCH 704 to TRP1 and/or PUSCH 706 to TRP2 is different from the priority index of PUCCH, the UE may transmit three channels (e.g., PUCCH 702PUSCH 704 and/or PUSCH 706) in parallel (e.g., simultaneously). In some examples, the UE transmits three channels when the UE supports parallel (e.g., simultaneous) PUSCH and PUCCH transmissions (e.g., with different priority indexes). In some examples, the UE transmits three channels when cell 1 and cell 2 are in different frequency bands (e.g., inter-band cells). In some examples, the UE may be configured to transmit PUSCH and PUCCH in parallel (e.g., whether the UE transmits PUSCH and PUCCH in parallel is based on the configuration in which the UE is configured), with one of PUSCH or PUCCH (e.g., PUCCH 702, PUSCH 704, or PUSCH 706) associated with FDM/SDM mTRP operation (e.g., parallel (e.g., simultaneous) transmissions within one serving cell). In some examples, PUCCH (e.g., PUCCH 702) may include UCI associated with a priority index=1 (e.g., higher priority), and PUSCHs 704 and 706 to TRP1 and TRP2 may be associated with a priority index=0 (e.g., lower priority). In some examples, if the UE does not support parallel (e.g., simultaneous) transmission of PUSCH and PUCCH, the UE prioritizes and/or transmits channels with higher priority index (e.g., higher priority), and/or discards or does not transmit channels with lower priority index (e.g., lower priority).
In some examples, the UE may treat both PUSCHs as a pair of PUSCHs. In some examples, for the pair of PUSCHs, one PUSCH may be used as a reference PUSCH. In some examples, the reference PUSCH may begin earlier than the other PUSCH of the pair of PUSCHs. In some examples, the reference PUSCH may be associated with a lower or higher index (e.g., CORESETPoolindex, TRP group index, SRS resource set index) than the other PUSCH of the pair of PUSCHs. In some examples, the UE uses at least the reference PUSCH when the UE multiplexes UCI into PUSCH (e.g., the UE multiplexes UCI into at least the reference PUSCH). In some examples, once the reference PUSCH is multiplexed with UCI, the other PUSCH in the pair is also multiplexed with UCI. In some examples, the UE multiplexes UCI into the reference PUSCH and, after multiplexing UCI into the reference PUSCH, the UE multiplexes UCI into another PUSCH. In some examples, when performing the multiplexing procedure, PUSCHs in a pair that are not reference PUSCHs are excluded from use in determining multiplexing (e.g., another PUSCH may not be used for multiplexing UCI and/or a reference PUSCH may be the only PUSCH used for multiplexing UCI). Alternatively and/or additionally, the UE may only multiplex UCI on the reference PUSCH and/or may not multiplex UCI on the other PUSCH (not the reference PUSCH) of the pair of PUSCHs. In some examples, when the UE multiplexes UCI on PUSCH, the UE discards PUCCH to cell 1.
Fig. 8 shows a timing diagram of an exemplary scenario 800 associated with a PUSCH 806 transmitted by a UE to cell 2, a PUCCH 802 to TRPA of cell 1, and a PUCCH 804 to TRPB of cell 1, where the three channels overlap (e.g., at least partially overlap) in the time domain. In some examples, the starting symbol of PUCCH 802 to TRPA of cell 1 and the starting symbol of PUCCH 804 to TRPB of cell 1 may be different (as shown in the exemplary scenario 800 of fig. 8) or the same. In some examples, the UE may transmit PUCCH 802 to the TRPA of cell 1 via the first joint/UL TCI state and/or the first spatial relationship. In some examples, the UE may transmit PUCCH 804 to the TRPB of cell 1 via the second combined/UL TCI state and/or the second spatial relationship. In some examples, the UE may transmit to PUSCH 806 of cell 2 via a third combined/UL TCI state and/or a third spatial relationship. In some examples, the UE may receive a first beam indicating DCI for cell 2 and a second beam indicating DCI for cell 1 (e.g., because cell 1 and cell 2 are inter-band cells). In some examples, the three channels are (at least) in the same time slot/sub-time slot.
In some examples, UCI0 (e.g., discussed with respect to the sixth concept in the foregoing description) and UCI1 (e.g., discussed with respect to the sixth concept in the foregoing description) are multiplexed on PUCCH 802 to TRPA and PUCCH 804 to TRPB, respectively, when the starting symbols of the two PUCCHs 802 and 804 are the same (e.g., the two PUCCHs 802 and 804 start at the same starting symbol). Alternatively and/or additionally, the UE may multiplex UCI0+ UCI1 (e.g., discussed in relation to the sixth concept in the foregoing description) on PUCCH 802 to the TRPA (e.g., associated with the first index). Alternatively and/or additionally, the UE may multiplex UCI0+ UCI1 on PUCCHs 802 and 804.
In some examples, for the joint HARQ feedback mode, PUSCH 806 to cell 2 may include UCI from PUCCHs 802 and 804 (and/or UCI0 and UCI1 discussed with respect to the sixth concept in the foregoing description, for example).
In some examples, for per-TRP UCI multiplexing, PUSCH 806 to cell 2 may be determined to be associated with the first index when PUSCH 806 to cell 2 is not configured with an index associated with a TRP (e.g., when PUSCH 806 to cell 2 is not configured with an index associated with a TRP and/or when a UE is not configured with a TRP associated with PUSCH 806). In some examples, the UE may multiplex UCI to PUCCH 802 of the TRPA into PUSCH 806 of cell 2.
In some examples, considering the priority index aspect, after multiplexing UCI to PUCCH 802 of TRPA into PUSCH 806 of cell 2, the UE may transmit PUCCH 804 to TRPB and PUSCH 806 to cell 2 in parallel (e.g., simultaneously) (e.g., with UCI to PUCCH 802 of TRPA). In some examples, when cell 1 and cell 2 are inter-band cells (e.g., cell 1 and cell 2 are associated with different frequency bands) and/or the UE supports simultaneous transmission of PUCCH and PUSCH, the UE transmits PUCCH 804 to TRPB and PUSCH 806 to cell 2 in parallel (e.g., simultaneously). In some examples, the priority index of PUCCH 804 to TRPB may be the same or different than the priority index of PUSCH 806 to cell 2. In some examples, for PUSCH with multiplexed UCI from PUCCH 802 to TRPA, if the priority index of PUCCH 804 to TRPB is different from the priority index of PUSCH to cell 2, the higher priority index may be determined to be the priority index of PUSCH with multiplexed UCI. In some examples, for inter-TRP groups between cells (e.g., inter-TRP groups may refer to having different TRP group indices, e.g., where cell 1 is associated with a different TRP group index than cell 2), parallel (e.g., simultaneous) PUCCH and PUSCH transmissions on different cells (e.g., inter-band cells) may be associated with the same priority index or different priority indices. In some examples, for inter-TRP intra-group between cells (e.g., cell 1 and cell 2 are associated with the same TRP group index), parallel (e.g., simultaneous) PUCCH and PUSCH transmissions on different cells (e.g., inter-band cells) are associated with different priority indices.
In some examples, the UE may treat both PUCCHs as a pair of PUCCHs. In some examples, for the pair of PUCCHs, one PUCCH may be used as a reference PUCCH. In some examples, the reference PUCCH may start earlier than the other PUCCH of the pair of PUCCHs. In some examples, the reference PUCCH may be associated with a lower or higher index (e.g., CORESETPoolindex, TRP group index, SRS resource set index) than the other PUCCH of the pair of PUCCHs. In some examples, the UE uses at least the reference PUCCH when the UE multiplexes UCI into PUSCH (e.g., the UE multiplexes at least UCI of the reference PUCCH into PUSCH). In some examples, once a reference PUCCH (e.g., UCI corresponding to the reference PUCCH) is multiplexed into PUSCH, the other PUCCH in the pair is also multiplexed into PUSCH. In some examples, the UE multiplexes a reference PUCCH (e.g., UCI corresponding to the reference PUCCH) into PUSCH, and after multiplexing the reference PUCCH into PUSCH, the UE multiplexes another PUCCH (e.g., UCI corresponding to another PUCCH) into PUSCH (e.g., PUSCH 806). In some examples, PUCCHs in a pair that are not reference PUCCHs are excluded from determining multiplexing when performing the multiplexing procedure (e.g., another PUCCH may not be multiplexed into PUSCH, and/or a reference PUCCH may be the only PUCCH multiplexed into PUSCH). Alternatively and/or additionally, the UE may only multiplex UCI of the reference PUCCH and/or may not multiplex UCI of the other PUCCH (not the reference PUCCH) of the pair of PUCCHs. In some examples, the motivation and/or the underlying theory (e.g., for UCI multiplexing only reference PUCCHs) may be that the same UCI content is associated with the pair of PUCCHs (e.g., UCI of reference PUCCH is the same as UCI of another PUCCH). In some examples, the pair of PUCCHs may be associated with the same UCI content when the sdi schedules PUCCHs with FDM/SDM mTRP operations (e.g., parallel (e.g., simultaneous) PUCCH transmissions associated with the DCI). In some examples, for a mdis mTRP PUCCH, a pair of PUCCHs may be applicable.
Fig. 9 shows a timing diagram of an exemplary scenario 900 associated with a PUSCH 906 of a UE transmitting to TRP1 of cell 2, a PUSCH 908 of TRP2 of cell 2, a PUCCH 902 of TRPA of cell 1, and a PUCCH 904 of TRPB of cell 1, wherein the four channels overlap in the time domain. In some examples, the starting symbol of PUCCH 902 to TRPA of cell 1 and the starting symbol of PUCCH 904 to TRPB of cell 1 may be different (as shown in exemplary scenario 900 of fig. 9) or the same. In some examples, the UE may transmit the PUCCH 902 to the TRPA of cell 1 via the first joint/UL TCI state and/or the first spatial relationship. In some examples, the UE may transmit the PUCCH 904 to the TRPB of cell 1 via the second combined/UL TCI state and/or the second spatial relationship. In some examples, the UE may transmit to PUSCH 906 of TRP1 of cell 2 via a third combined/UL TCI state and/or a third spatial relationship. In some examples, the UE may transmit to PUSCH 908 of TRP2 of cell 2 via a fourth combined/UL TCI state and/or a fourth spatial relationship. In some examples, the UE may receive a first beam indicating DCI for cell 2 and a second beam indicating DCI for cell 1 (e.g., because cell 1 and cell 2 are inter-band cells). In some examples, the four channels are (at least) in the same time slot/sub-time slot.
In some examples, the UE may multiplex UCI to PUCCH 902 of TRPA into PUSCH 906 of TRP1 based on the same TRP group index (e.g., the UE may multiplex UCI to PUCCH 902 of TRPA into PUSCH 906 of TRP1 based on TRPA and TRP1 being associated with the same TRP group index). In some examples, the UE may multiplex UCI to PUCCH 904 of TRPB into PUSCH 908 of TRP2 based on the same TRP group index (e.g., the UE may multiplex UCI to PUCCH 904 of TRPB into PUSCH 908 of TRP2 based on TRPB and TRP2 being associated with the same TRP group index).
In some examples, embodiments of the present disclosure may incorporate any of the techniques provided herein with respect to fig. 7-9. In some examples, the techniques provided herein with respect to fig. 7-9 may be implemented independently and/or separately. Alternatively and/or additionally, some embodiments of the present disclosure may incorporate a combination of some and/or all of the techniques from fig. 7-9.
With respect to one or more embodiments herein, in some examples, for FDM mTRP operation for a PUCCH, one PUCCH and another PUCCH in a serving cell may overlap in the time domain. The one PUCCH and the other PUCCH may partially overlap each other in the frequency domain. Alternatively and/or additionally, the one PUCCH and the other PUCCH may occupy different PRB sets. Alternatively and/or additionally, the PRBs for the one PUCCH and the other PUCCH may be identical (e.g., identical) (e.g., a pair of PRBs may be occupied and the symbols may be different). In some examples, each of the one PUCCH and the other PUCCH may occupy one or more PRBs (e.g., a pair of PRBs), wherein the one PUCCH occupies one or more first symbols of the one or more PRBs and the other PUCCH occupies one or more second symbols of the one or more PRBs, and wherein the one or more first symbols are different from the one or more second symbols.
In some examples, for SDM mTRP operation for a PUCCH, one PUCCH and another PUCCH in a serving cell may overlap in the time domain. The PRBs for the one PUCCH and the other PUCCH may be identical (e.g., identical).
In some examples, for FDM mTRP operation for PUSCH, one PUSCH and another PUSCH in a serving cell may overlap in the time domain. The one PUSCH and the other PUSCH may partially overlap each other in the frequency domain. Alternatively and/or additionally, the one PUSCH and the other PUSCH may occupy different sets of PRBs. Alternatively and/or additionally, the PRBs for the one PUSCH and the other PUSCH may be identical (e.g., identical) (e.g., a pair of PRBs may be occupied and the symbols may be different). In some examples, each of the one PUSCH and the another PUSCH may occupy one or more PRBs (e.g., a pair of PRBs), wherein the one PUSCH occupies one or more first symbols of the one or more PRBs and the another PUSCH occupies one or more second symbols of the one or more PRBs, and wherein the one or more first symbols are different from the one or more second symbols.
In some examples, for SDM mTRP operation for PUSCH, one PUSCH and another PUSCH in a serving cell may overlap in the time domain. The PRBs for the one PUSCH and the other PUSCH may be identical (e.g., identical).
For a Physical Downlink Shared Channel (PDSCH) in NR Rel-15, the UE may receive a Medium Access Control (MAC) Control Element (CE) (e.g., discussed in section 6.1.3.14 of 3GPP TS 38.321V17.0.0) for indicating up to 8 out of a maximum number of configured Transmit Configuration Indicator (TCI) states (e.g., a maximum number of configured TCI states), e.g., 128 TCI states. The UE may receive Downlink Control Information (DCI) having a TCI field indicating a code point (e.g., one code point) associated with a MAC CE indicating a TCI state. In NR Rel-15, a beam indication for receiving a Downlink (DL) transmission may, for example, be considered from the perspective of a UE (e.g., may only be considered) from transmissions of a single TRP and/or transmissions of a panel within a usage duration (e.g., duration of at least one of one or more time slots, e.g., one time slot, etc.).
In NR Rel-16, downlink transmissions from multiple TRPs and/or multiple panels may be considered. For transmissions from multiple TRPs and/or multiple panels, it may be implied that a single downlink transmission (e.g., for a single Transport Block (TB)) may be performed using different beams from multiple TRPs and/or multiple panels (e.g., for transmissions from multiple TRPs and/or multiple panels, it may be implied that a single downlink transmission may be performed using different beams from multiple TRPs and/or multiple panels). Alternatively and/or additionally, it may be implied (for transmissions from multiple TRPs and/or multiple panels, for example) that the UE may receive multiple downlink transmissions from multiple TRPs and/or multiple panels within a duration (e.g., a duration of at least one of one or more time slots, e.g., one time slot, one or more time slots of one time slot, etc.). In NR Rel-16, one or more enhancements to ultra-reliable and low latency communications (URLLC) have been made to consider multi-TRP scenarios. Alternatively and/or additionally, one or more Physical Downlink Shared Channel (PDSCH) repetition schemes may be used to improve the reliability of receiving PDSCH. For example, the one or more PDSCH repetition schemes may include at least one of a Space Division Multiplexing (SDM) repetition scheme, a Frequency Division Multiplexing (FDM) repetition scheme, a micro-slot based repetition scheme, a slot based repetition scheme, and the like. For a multi-TRP (mTRP) PDSCH, TBs (e.g., one TB) may be transmitted over multiple beams, TCI states, and/or spatial relationships. To indicate two TCI states for mTRP with a single DCI, a MAC CE (e.g., discussed in section 6.1.3.24 in 3GPP TS 38.321V17.0.0) may be used to associate one or more code points of a TCI field to one or more TCI state IDs. In some examples, the MAC CE may associate at most 16 TCI state IDs (e.g., the MAC CE may associate one or more code points of the TCI field to at most 16 TCI state IDs), and the field (e.g., field Ci) may indicate one TCI state or two TCI states for the code points of the TCI field (e.g., the code points of the TCI field may be associated with one or two TCI states). In some examples, the UE may receive DCI with a TCI field indicating a code point (e.g., one code point), and if the one code point indicates one TCI state as a MAC CE association (e.g., if the MAC CE indicates that the one code point is associated with only one TCI state), the UE may consider a single TRP (e.g., the UE may determine that the MAC CE and/or the one code point is associated with only a single TRP and/or may perform a single TRP operation), while if the one code point indicates two TCI states as a MAC CE association (e.g., if the MAC CE indicates that the one code point is associated with two TCI states), the UE may consider mTRP (e.g., the UE may determine that the MAC CE and/or the one code point is associated with multiple TRPs and/or may perform a mTRP operation).
With respect to one or more embodiments herein, in some examples, the beam-indicating DCI may provide a TCI code point of a TCI bit field.
With respect to one or more embodiments herein, in some examples, a TCI code point may indicate one joint TCI state, two joint TCI states, one DL TCI state, one UL TCI state, one DL TCI state+one UL TCI state, two DL TCI states, two UL TCI states, two DL TCI states+one UL TCI state, one DL TCI state+two UL TCI states, or two DL TCI states+two UL TCI states.
With respect to one or more embodiments herein, in some examples, a MAC CE may indicate an association between one or more TCI code points and corresponding TCI states.
With respect to one or more embodiments herein, in some examples, based on the beam indication DCI, the UE may apply the indicated TCI status for at least the UE-specific downlink channel/signal and/or the UE-specific uplink channel/signal and/or one or more channels configured with a follow unifiedtcstate.
With respect to one or more embodiments herein, in some examples, the beam indicates DCI may or may not schedule a downlink assignment.
With respect to one or more embodiments herein, in some examples, a UE applies an indicated TCI state from a first slot/symbol after a time interval from transmission of an Acknowledgement (ACK) (e.g., HARQ ACK) in response to a beam-indicating DCI and/or a downlink assignment of the beam-indicating DCI.
With respect to one or more embodiments herein, in some examples, when the scheduling DCI has a TCI bit field indicating a TCI code point different from the TCI state of the current application/use, the UE may determine/consider that the scheduling DCI is also beam indicating DCI.
With respect to one or more embodiments herein, in some examples, when the scheduling DCI has a TCI bit field indicating the same TCI code point as the currently applied/used TCI state, the UE may determine/consider that the scheduling DCI is only the scheduling DCI (and not the beam indicating DCI).
With respect to one or more embodiments herein, in some examples, the first joint/UL TCI state is associated with a first index (e.g., coresetpoolndex=0, first TRP group index).
With respect to one or more embodiments herein, in some examples, the second joint/UL TCI state is associated with a second index (e.g., coresetpoolndex=1, second TRP group index).

With respect to one or more embodiments herein, in some examples, one cell of the fourth plurality of cells may be a serving cell or a cell with an additionalapci/additionalalicindex.
In NR Rel-17 there may be attempts to have a unified beam indication framework for DL and UL, for UE specific DL channels and/or signals and/or for UE specific UL channels and/or signals. The motivation (e.g., motivation with a unified beam indication framework) may be to reduce signaling overhead and have a unified framework for DL channels and/or signals and/or for UL channels and/or signals. The motivation (e.g., motivation with a unified beam indication framework) may be that the UE (e.g., in a truest deployment) may use one or more identical UE beams for downlink reception and/or one or more identical UE beams for uplink transmission. Alternatively and/or additionally, in the frequency range 2 (FR 2) band (e.g., a typical FR2 band), beam correspondence may be rationalized as having a joint beam (e.g., one joint beam) for DL and UL, as it may be a major context and/or problem. However, due to some MPE issues for some UE beams (e.g., taking into account adjustments of maximum transmit power limits for the human body relative to some UE beams), joint beams for DL and UL cannot be guaranteed, while separate beam indications for DL and UL may be used for this scenario. For separate DL/UL TCI states, regarding signaling overhead, beam indication of two TCI states corresponding to DL TCI state and UL TCI state may be considered.
With respect to one or more embodiments herein, in some examples, a UE (e.g., a first UE) has the capability to transmit two PUSCHs in parallel (e.g., simultaneously) on one serving cell.
With respect to one or more embodiments herein, in some examples, a UE (e.g., a first UE) has the capability to transmit two PUCCHs in parallel (e.g., simultaneously) on one serving cell.
With respect to one or more embodiments herein, in some examples, TRP (e.g., as mentioned in the foregoing description) may be associated with a CORESET pool (e.g., coresetpoolndex) of a cell. In some embodiments, one, some, and/or all instances of the term "TRP" in the present disclosure may be replaced with the term "CORESET pool". In some examples, for a UE performing a single TRP operation on a cell, the UE may receive and/or monitor signaling from the cell via a single CORESET pool. In some examples, for a UE performing multi-TRP operations on a cell, the UE may receive and/or monitor signaling from the cell via multiple CORESET pools.
Alternatively and/or additionally, TRP (e.g., mentioned in the foregoing description) may be associated with SRS resources (and/or SRS resource sets) of a cell. In some embodiments, one, some, and/or all instances of the term "TRP" in the present disclosure may be replaced with the term "SRS resource" and/or the term "SRS resource set. In some examples, for a UE performing a single TRP operation on a cell, the UE may receive and/or monitor signaling on the cell via one activated TCI state. In some examples, for a UE performing multi-TRP operations on a cell, the UE may receive and/or monitor signaling via a plurality of activated TCI states.
Alternatively and/or additionally, TRP (e.g., mentioned in the foregoing description) may be associated with one or more TCI states of a cell. In some embodiments, one, some, and/or all instances of the term "TRP" in the present disclosure may be replaced with the term "TCI state" and/or the term "one or more TCI states". In some examples, for a UE performing a single TRP operation on a cell, the UE may transmit SRS on the cell via one SRS resource. In some examples, for a UE performing a multi-TRP operation on a cell, the UE may transmit SRS via a plurality of SRS resources, where each of the plurality of SRS resources may be associated with a (different) TRP.
Alternatively and/or additionally, TRP (e.g., mentioned in the foregoing description) may be associated with PUSCH or PUCCH. In some embodiments, one, some, and/or all instances of the term "TRP" in the present disclosure may be replaced with the term "PUSCH" and/or the term "PUCCH". For a UE performing intra-cell mTRP operations on a cell, the UE may perform UL transmissions via multiple PUSCHs associated with the cell. For UEs performing inter-cell mTRP operations on a cell, the UE may perform UL transmissions via multiple PUSCHs associated with different cells, where the UL transmissions may include transmitting the same TB on different PUSCHs associated with different cells.
Alternatively and/or additionally, TRP (e.g. mentioned in the foregoing description) may be associated with spatial relationship information of a cell.

Fig. 10 is a flow chart 1000 from the perspective of a UE according to an exemplary embodiment. In step 1005, the UE determines that a first channel (e.g., one channel) of two overlapping channels in a time domain is for UCI multiplexing, wherein the two overlapping channels have a same starting symbol in a first serving cell (e.g., the two overlapping channels start at a same starting symbol), and wherein a first index associated with the first channel of the two overlapping channels is lower than a second index associated with a second channel of the two overlapping channels. A first channel of the two overlapping channels at least partially overlaps a second channel of the two overlapping channels. In an example, the UE selects a first channel (e.g., from the two overlapping channels) for UCI multiplexing based on the first index being lower than the second index.
In one embodiment, the first index may be a first SRS resource set index and/or the second index may be a second SRS resource set index.
In one embodiment, the first index may be a first TRP index and/or the second index may be a second TRP index.
In one embodiment, the first index may be a first TRP group index and/or the second index may be a second TRP group index.
In one embodiment, the first index may be a first coresetpoolndex and/or the second index may be a second coresetpoolndex.
In one embodiment, the first index may correspond to a first joint/UL TCI state (e.g., a 1 st joint/UL TCI state) and/or the second index may correspond to a second joint/UL TCI state (e.g., a 2 nd joint/UL TCI state). The first combined/UL TCI state may be associated with a first channel and/or the second combined/UL TCI state may be associated with a second channel. The first and/or second joint/UL TCI status may be indicated by a beam indication DCI. In some examples, the first index may correspond to a first octet index of the first combined/UL TCI state (e.g., a TCI code point may indicate the first octet index for the first combined/UL TCI state), and/or the second index may correspond to a second octet index of the second combined/UL TCI state (e.g., a TCI code point may indicate the second octet index for the second combined/UL TCI state).
In one embodiment, a first channel of the two overlapping channels may include two PUSCHs associated with different joint/UL TCI states.
In one embodiment, a first channel of the two overlapping channels may include a first PUSCH associated with a first joint/UL TCI state, and a second channel of the two overlapping channels may include a second PUSCH associated with a second joint/UL TCI state different from the first joint/UL TCI state.
In one embodiment, the first channel of the two overlapping channels is only one channel (e.g., only the first PUSCH) of the two overlapping channels (e.g., the first PUSCH and the second PUSCH).
In one embodiment, a UE supports parallel (e.g., simultaneous) uplink transmissions via multiple UE panels.

In one embodiment, the UE transmits a second channel of the two overlapping channels via a second combined/UL TCI state (e.g., a 2 nd combined/UL TCI state).
Referring now to fig. 3 and 4, in one exemplary embodiment of a UE, apparatus 300 includes program code 312 stored in memory 310. CPU 308 may execute program code 312 to enable a UE to determine that a first channel of two overlapping channels in a time domain is used for UCI multiplexing, wherein the two overlapping channels have the same starting symbol in a first serving cell, and wherein a first index associated with the first channel of the two overlapping channels is lower than a second index associated with a second channel of the two overlapping channels. Further, the CPU 308 may execute the program code 312 to perform one, some, and/or all of the acts and steps described above and/or other acts and steps described herein.
Fig. 11 is a flow chart 1100 from the perspective of a UE according to an example embodiment. In step 1105, the UE multiplexes and/or transmits UCI on both of the two parallel (e.g., simultaneous) PUSCHs/PUCCHs on the serving cell based on the presence of two parallel PUSCHs/PUCCHs with the same starting symbol on the serving cell for multiplexing UCI. In some examples, a UE determines to use a serving cell for multiplexing (and/or transmitting) UCI based on the serving cell having a lowest serving cell among a plurality of serving cells (e.g., associated with the UE) (e.g., the UE selects the serving cell from among the plurality of serving cells for multiplexing and/or transmitting UCI).
In an example, the two parallel PUSCHs/PUCCHs include a first channel (e.g., a first PUSCH or a first PUCCH) and a second channel (e.g., a second PUSCH or a second PUCCH). The UE transmits a first channel and a second channel on a serving cell. The first PUSCH transmitted on the first cell includes UCI (e.g., at least a portion of UCI), and/or the second PUSCH transmitted on the second cell includes UCI (e.g., at least a portion of UCI). For example, UCI (e.g., at least a portion of UCI) may be multiplexed into a first PUSCH and/or UCI (e.g., at least a portion of UCI) may be multiplexed into a second PUSCH.
In one embodiment, the plurality of serving cells are associated with a cell group.

CPU 308 may execute program code 312 to enable a UE to multiplex and/or transmit UCI on both two parallel (e.g., simultaneous) PUSCHs/PUCCHs on a serving cell based on the presence of the two parallel PUSCHs/PUCCHs on the serving cell with the same starting symbol for multiplexing UCI. Further, the CPU 308 may execute the program code 312 to perform one, some, and/or all of the acts and steps described above and/or other acts and steps described herein.
Fig. 12 is a flow diagram 1200 from the perspective of a UE according to an example embodiment. In step 1205, the UE is configured with a first serving cell and a second cell (e.g., a second serving cell). For example, the UE may be configured with the first serving cell via a cell configuration associated with the first serving cell received by the UE. The UE may be configured with the second cell via a cell configuration associated with the second cell received by the UE. In step 1210, the UE is configured with a first index and/or a second index for the first serving cell (and/or for one or more other serving cells other than the first serving cell). For example, the UE may receive an indication of the first index and/or the second index. In step 1215, the UE determines whether to transmit the first channel and the second channel in parallel (e.g., simultaneously) based on whether the first channel on the first serving cell is associated with (i) the same configured index as the second channel on the second channel, or (ii) a different configured index than the second channel on the second cell. In some examples, the first channel and the second channel are associated with the same priority index. In some examples, the first channel and the second channel at least partially overlap each other in the time domain.
In one embodiment, the first serving cell and the second cell are in different frequency bands (e.g., inter-band cells).
In one embodiment, the UE supports parallel transmission of PUSCH and PUCCH on different cells. For example, the UE has the capability to transmit PUSCH and PUCCH in parallel (e.g., simultaneously) on different cells.
In one embodiment, the first channel is PUSCH and the second channel is PUCCH.
In one embodiment, the first channel is PUCCH and the second channel is PUSCH.
In one embodiment, the UE (i) transmits the first channel and/or discards the second channel, (ii) transmits the second channel and/or discards the first channel, (iii) multiplexes the content of the first channel into the second channel (and, for example, transmits the second channel and/or discards the first channel), and/or (iv) multiplexes the content of the second channel into the first channel (and, for example, transmits the first channel and/or discards the second channel), based on a determination that the first channel on the first serving cell is associated with the same configured index (e.g., intra-frame TRP group) as the second channel on the second cell (e.g., the first channel and the second channel are associated with the same configured index, such as the same TRP group index). In some examples, the first channel and the second channel are associated with the same priority index.
In one embodiment, based on a determination that a first channel on a first serving cell and a configured index (e.g., an inter-TRP group) that is different from a second channel on a second cell are associated (e.g., a first index associated with the first channel, e.g., the first TRP group index is different from a second index associated with the second channel, e.g., the second TRP group index), the UE transmits (and/or is configured and/or allowed to transmit) the first channel and the second channel (e.g., have the same priority index) in parallel (e.g., simultaneously).
In one embodiment, the first index and/or the second index may each correspond to at least one of: (i) coresetpoinlindex, (ii) TRP group index, (iii) index associated with TRP, or (iv) index associated with TRP group.
In one embodiment, the second cell includes a serving cell (e.g., a second serving cell of the UE), and/or the second cell is not configured with an additionpci/additionpci index (e.g., the second cell is not configured with an additionpci/additionpci index and/or the UE is not configured with an additionpci/additionpci index for the second cell).
In one embodiment, the second cell is not a serving cell and/or the second cell is a neighboring cell (e.g., a neighboring cell of the first serving cell) and/or the second cell is configured with an additionpci/additionpci index.
In one embodiment, the priority index for the first channel and the second channel may be determined based on RRC signaling.
In one embodiment, the priority index for the first channel and the second channel may be indicated by DCI (e.g., downlink assignment DCI or uplink grant DCI).
Referring now to fig. 3 and 4, in one exemplary embodiment of a UE, apparatus 300 includes program code 312 stored in memory 310. CPU 308 may execute program code 312 to enable the UE to: (i) configured with a first serving cell and a second cell, (ii) configured with a first index and/or a second index for the first serving cell, and (iii) determining whether to transmit the first channel and the second channel in parallel (e.g., simultaneously) based on whether the first channel on the first serving cell is associated with (a) the same configured index as the second channel on the second channel or (B) with a different configured index than the second channel on the second cell. Further, the CPU 308 may execute the program code 312 to perform one, some, and/or all of the acts and steps described above and/or other acts and steps described herein.
Fig. 13 is a flow chart 1300 according to an exemplary embodiment from the perspective of a UE. In step 1305, the UE receives DCI scheduling two parallel (e.g., simultaneous) uplink transmissions/channels on a first serving cell, wherein the DCI requests a CSI report (e.g., an aperiodic CSI report). In some examples, the two parallel uplink transmissions/channels have the same starting symbol (e.g., the two parallel uplink transmissions/channels start at the same starting symbol). In some examples, the two parallel uplink transmissions/channels have different start symbols (e.g., the two parallel uplink transmissions/channels start at different start symbols). In an example, the CSI request field of the DCI is set to 1 (to indicate, for example, that the DCI requests CSI reporting). In step 1310, the UE transmits the AP CSI report (i) on one of two parallel uplink transmissions/channels (e.g., only one of the two parallel uplink transmissions/channels) or (ii) on both of the two parallel uplink transmissions/channels.
In one embodiment, the UE determines whether to transmit and/or multiplex the AP CSI report on one or two transmission occasions based on: (i) whether there is an inter-slot/sub-slot repetition, (ii) whether two parallel uplink transmissions/channels have the same or different starting symbols, (iii) whether there is another UCI (e.g., available for transmission) other than AP CSI reporting, and/or (iv) a sdi/mdis based mTRP.
In one embodiment, one transmission occasion may correspond to one of two parallel uplink transmissions/channels. In some examples, two transmission occasions may correspond to the two parallel uplink transmissions/channels.
In one embodiment, when the two parallel uplink transmissions/channels have the same starting symbol (e.g., in a slot), the UE transmits an AP CSI report on the two parallel uplink transmissions/channels (e.g., each of the two parallel uplink transmissions/channels includes at least a portion of the AP CSI report). For example, the UE may transmit an AP CSI report using the two parallel uplink transmissions/channels based on the two parallel uplink transmissions/channels having the same starting symbol.
In one embodiment, when the two parallel uplink transmissions/channels have the same starting symbol (e.g., in a slot) and the UE may multiplex another UCI other than the AP CSI report (e.g., the UE has another UCI available for transmission other than the AP CSI report), the UE transmits the AP CSI report on one of the two parallel uplink transmissions/channels (e.g., multiplexes with the other UCI). For example, the UE may transmit the AP CSI report using one of the two parallel uplink transmissions/channels (e.g., only one of the two parallel uplink transmissions/channels) based on the two parallel uplink transmissions/channels having the same starting symbol and another UCI (e.g., available for transmission).
In one embodiment, when the two parallel uplink transmissions/channels have the same starting symbol (e.g., in a slot) and the UE may multiplex another UCI other than the AP CSI report (e.g., the UE has another UCI available for transmission other than the AP CSI report), the UE transmits the AP CSI report on the two parallel uplink transmissions/channels (e.g., multiplexed with the other UCI). For example, the UE may transmit the AP CSI report using the two parallel uplink transmissions/channels based on the two parallel uplink transmissions/channels having the same starting symbol and another UCI (e.g., available for transmission).
In one embodiment, when one of the two parallel uplink transmissions/channels (e.g., only the one of the two parallel uplink transmissions/channels) is used to transmit the AP CSI report (e.g., the AP CSI report is multiplexed into the one of the two parallel uplink transmissions/channels), the one of the two parallel uplink transmissions/channels may be determined (e.g., derived and/or selected) based on: (i) which uplink transmission/channel is associated with a first joint/UL TCI state (e.g., the one of the two parallel uplink transmissions/channels may be determined as an uplink transmission/channel associated with the first joint/UL TCI state), (ii) which uplink transmission/channel is associated with a joint/UL TCI state associated with a cell that is a serving cell and/or has no additionpci/additionpci index, (iii) which uplink transmission/channel is associated with a lower index (e.g., one of the two parallel uplink transmissions/channels may be determined as an uplink transmission/channel associated with a first set of downlink transmission/resources (e.g., SRS) and/or one of the two parallel uplink transmission/channels may be determined as a lower index (e.g., one of the two parallel transmission/resources) is associated with a first set of uplink transmission/resources (e.g., SRS) and/or one of the two parallel transmission/resources (SRS) may be determined as a lower index (e.g., one of the two parallel transmission/SRS) and/or one of the two parallel transmission/resources (SRS) may be associated with a second set of the lower index (e.g., the lower additionpci/additionpci index), the first SRS resource set index is lower than a second SRS resource set index associated with, for example, the other of the two parallel uplink transmissions/channels.
In one embodiment, the UE determines whether to transmit and/or multiplex the AP CSI report on one of two parallel uplink transmissions/channels (e.g., only one of the two parallel uplink transmissions/channels) or on the two parallel uplink transmissions/channels based on: (i) whether there is an inter-slot/sub-slot repetition, (ii) whether the two parallel uplink transmissions/channels have the same starting symbol or different starting symbols, (iii) whether there is another UCI (e.g., available for transmission) other than an AP CSI report, and/or (iv) a sdi/mdis based mTRP.
Referring now to fig. 3 and 4, in one exemplary embodiment of a UE, apparatus 300 includes program code 312 stored in memory 310. CPU 308 may execute program code 312 to enable the UE to: (i) Receiving DCI scheduling two parallel uplink transmissions/channels on a first serving cell, wherein the DCI requests a CSI report, and (ii) transmitting an AP CSI report (a) on one of the two parallel uplink transmissions/channels (e.g., only one of the two parallel uplink transmissions/channels) or (B) on the two parallel uplink transmissions/channels. Further, the CPU 308 may execute the program code 312 to perform one, some, and/or all of the acts and steps described above and/or other acts and steps described herein.
Fig. 14 is a flow diagram 1400 from the perspective of a UE according to an exemplary embodiment. In step 1405, the UE receives one or more signals indicating a first PUSCH on a first cell and a second PUSCH on the first cell. The first PUSCH and the second PUSCH are in a TTI (e.g., at least a portion of the first PUSCH is in a TTI and/or at least a portion of the second PUSCH is in a TTI). The start symbol of the first PUSCH is the same as the start symbol of the second PUSCH. Thus, the first PUSCH and the second PUSCH may overlap (e.g., at least partially overlap) in the time domain. The one or more signals may include (where, for example, the time resources allocated for the first PUSCH at least partially overlap with the time resources allocated for the second PUSCH). In step 1410, the UE determines to transmit first Uplink Control Information (UCI) on a first cell and in a TTI, wherein the first UCI overlaps (e.g., at least partially overlaps) with a first PUSCH and a second PUSCH in a time domain. In step 1415, the UE selects a first PUSCH for multiplexing the first UCI based on whether the UE is configured with a joint HARQ feedback mode or a separate HARQ feedback mode. For example, the UE may select the first PUSCH for multiplexing the first UCI based on whether the UE is configured with a joint HARQ feedback mode or a separate HARQ feedback mode. In some examples, the UE selects the first PUSCH for multiplexing the first UCI based on other information (e.g., in addition to whether the UE is configured with a joint HARQ feedback mode or a separate HARQ feedback mode). In step 1420, the UE transmits (e.g., transmits in parallel) a first PUSCH and a second PUSCH on a first cell, wherein the first PUSCH transmitted on the first cell includes a first UCI. For example, the UE may multiplex the first UCI into the first PUSCH (e.g., the UE may multiplex at least a portion of the first UCI into the first PUSCH). In some examples, the first PUSCH and the second PUSCH are transmitted in a TTI.
In some examples, the joint HARQ feedback mode is associated with transmitting UCI for different TRPs in the same PUCCH or the same PUSCH. In some examples, when the UE is configured with the joint HARQ feedback mode, the UE may transmit UCI for different TRPs in the same PUCCH or the same PUSCH.
In some examples, separate HARQ feedback modes are associated with transmitting UCI for different TRPs in different PUCCHs and/or different PUSCHs. In some examples, when the UE is configured with a separate HARQ feedback mode, the UE may transmit UCI for different TRPs in different PUCCHs or different PUSCHs.
In one embodiment, the UE selects a first PUSCH for multiplexing the first UCI based on the UE being configured with a joint HARQ feedback mode: (i) a first SRS resource set index associated with the first PUSCH is lower than a second SRS resource set index associated with the second PUSCH, (ii) a first TRP index associated with the first PUSCH is lower than a second TRP index associated with the second PUSCH, (iii) a first TRP group index associated with the first PUSCH is lower than a second TRP group index associated with the second PUSCH, and/or (iv) a first CORESET pool index (e.g., coresetpoolndex) associated with the first PUSCH is lower than a second CORESET Chi Suoyin (e.g., coresetpoolndex) associated with the second PUSCH. In an example, the second PUSCH transmitted on the first cell does not include the second UCI.
In one embodiment, the UE selects the first PUSCH for multiplexing the first UCI based on the UE being configured with a separate HARQ feedback mode and: (i) The first PUCCH and the first PUSCH are associated with a same Transmission Configuration Indicator (TCI) state, wherein the first PUCCH is associated with the first UCI, and/or (ii) the first PUCCH and the first PUSCH are associated with a same control resource set (CORESET) pool index. In an example, the second PUSCH transmitted on the first cell does not include the first UCI.
In one embodiment, the UE receives one beam indication DCI indicating a first joint/UL TCI state (e.g., 1 st joint/UL TCI state) and a second joint/UL TCI state (e.g., 2 nd joint/UL TCI state). In some examples, the octet index associated with the first combined/UL TCI state (e.g., the 1 st combined/UL TCI state) is lower than the octet index associated with the second combined/UL TCI state (e.g., the 2 nd combined/UL TCI state). In some examples, when the UE is configured with a sdi multiple transmission/reception point (mTRP), the UE receives one beam indication DCI (which may, for example, indicate both a first joint/UL TCI state and a second joint/UL TCI state).
In one embodiment, the UE receives a first beam indication DCI indicating a first joint/UL TCI state (e.g., 1 st joint/UL TCI state) and receives a second beam indication DCI indicating a second joint/UL TCI state (e.g., 2 nd joint/UL TCI state). In some examples, when the UE is configured with a mdis mTRP, the UE receives a first beam indicating DCI (which may, for example, indicate a first joint/UL TCI state) and a second beam indicating DCI (which may, for example, indicate a second joint/UL TCI state). For example, when the UE is configured with mci mTRP, the UE may not receive one beam indication DCI indicating the first and second combined/UL TCI states (both).
In one embodiment, a first signal of the one or more signals indicates a first PUSCH. The first signal may correspond to a first UL grant associated with the first PUSCH and/or a first configuration associated with the first PUSCH (e.g., the UE may be configured with the first configuration via the first signal). The first signal may indicate that the first PUSCH is associated with a first joint/UL TCI state (e.g., the first signal may indicate, either explicitly and/or implicitly, that the first joint/UL TCI state applies to the first PUSCH). In some examples, the first PUSCH is determined to be associated with the first joint/UL TCI state based on a first CORESET pool index associated with the first signal being 0 (e.g., the first CORESET pool index may correspond to CORESET poillolndex for CORESET of the first signal) (e.g., the UE may determine that the first PUSCH is associated with the first joint/UL TCI state based on the first CORESET pool index being 0). In some examples, the first signal schedules and/or configures a first PUSCH.
In some examples, a first signal of the one or more signals schedules a first PUSCH and a second signal of the one or more signals schedules a second PUSCH.
In one embodiment, a second signal of the one or more signals indicates a second PUSCH. The second signal may correspond to a second UL grant and/or a second configuration (e.g., the UE is configured via the second signal). The second signal may indicate that the second PUSCH is associated with a second joint/UL TCI state (e.g., the second signal may indicate, either explicitly and/or implicitly, that the second joint/UL TCI state applies to the second PUSCH). In some examples, the second PUSCH is determined to be associated with the second joint/UL TCI state based on a second CORESET pool index associated with the second signal being 1 (e.g., the second CORESET pool index may correspond to CORESET poillolndex for the second signal) (e.g., the UE may determine that the second PUSCH is associated with the second joint/UL TCI state based on the first CORESET pool index being 1). In some examples, the second signal schedules and/or configures a second PUSCH.
In one embodiment, the first and/or second joint/UL TCI states are configured for transmission of one or more UE-specific UL channels.
In one embodiment, the UE determines to transmit a second UCI on the first cell and in the TTI, wherein the second UCI overlaps with the first PUSCH and the second PUSCH in the time domain.
In one embodiment, the first UCI and the second UCI correspond to the same PUCCH group. In one embodiment, the first UCI corresponds to (e.g., includes) first HARQ information responsive to a first downlink assignment over a first CORESET associated with a first CORESET pool index (e.g., CORESET pool index) corresponding to (e.g., equal to) 0, wherein the second UCI corresponds to (e.g., includes) second HARQ information responsive to a second downlink assignment over a second CORESET associated with a second CORESET Chi Suoyin (e.g., CORESET pool index) corresponding to (e.g., equal to) 1.
In one embodiment, the first UCI is associated with a first PUCCH. A third signal including the first DCI signal and/or the first RRC signal indicates that the first PUCCH is associated with the first joint/UL TCI state (e.g., the third signal may indicate that the first joint/UL TCI state is applied to the first PUCCH). The UE may receive a third signal.
In one embodiment, the second UCI is associated with a second PUCCH.
In one embodiment, a fourth signal including a second DCI signal and/or a second RRC signal indicates that the second PUCCH is associated with a second combined/UL TCI state (e.g., the fourth signal may indicate that the second combined/UL TCI state is applied to the second PUCCH). The UE may receive the fourth signal.
In one embodiment, the UE selects the first PUSCH for multiplexing the first UCI based on: (i) a first SRS resource set index associated with the first PUSCH is lower than a second SRS resource set index associated with the second PUSCH, (ii) a first TRP index associated with the first PUSCH is lower than a second TRP index associated with the second PUSCH, (iii) a first TRP group index associated with the first PUSCH is lower than a second TRP group index associated with the second PUSCH, and/or (iv) a first CORESET pool index (e.g., coresetpoolndex) associated with the first PUSCH is lower than a second CORESET Chi Suoyin (e.g., coresetpoolndex) associated with the second PUSCH.
In one embodiment, the UE selects the first PUSCH for multiplexing the second UCI based on the UE being configured with a joint HARQ feedback mode: (i) a first SRS resource set index associated with the first PUSCH is lower than a second SRS resource set index associated with the second PUSCH, (ii) a first TRP index associated with the first PUSCH is lower than a second TRP index associated with the second PUSCH, (iii) a first TRP group index associated with the first PUSCH is lower than a second TRP group index associated with the second PUSCH, and/or (iv) a first CORESET pool index (e.g., coresetpoolndex) associated with the first PUSCH is lower than a second CORESET Chi Suoyin (e.g., coresetpoolndex) associated with the second PUSCH. In an example, the second PUSCH transmitted on the first cell does not include the second UCI.
In one embodiment, the UE selects the second PUSCH for multiplexing the first UCI (in addition to, for example, selecting the first PUSCH for multiplexing the first UCI). The second PUSCH transmitted on the first cell includes the first UCI. For example, the UE may select the first PUSCH and the second PUSCH for multiplexing the first UCI. In an example, the first PUSCH transmitted on the first cell may include at least a portion of the first UCI, and the second PUSCH transmitted on the first cell may include at least a portion of the first UCI. In some examples, the UE may multiplex at least a portion of the first UCI into the first PUSCH and at least a portion of the first UCI into the second PUSCH.
In one embodiment, the UE selects the second PUSCH for multiplexing the second UCI based on the UE being configured with a separate HARQ feedback mode: (i) The second PUCCH and the second PUSCH are associated with the same TCI state, wherein the second PUCCH is associated with the second UCI, and/or (ii) the second PUCCH and the second PUSCH are associated with the same CORESET Chi Suoyin (e.g., coresetpoolndex). In an example, the second PUSCH transmitted on the first cell includes a second UCI.
In one embodiment, the UE selects the first PUSCH for multiplexing the first UCI based on: (i) SRS resource set index associated with the first PUSCH corresponds to SRS resource set index associated with the first UCI (e.g., the first PUSCH and the first UCI correspond to the same SRS resource set index), (ii) TRP index associated with the first PUSCH corresponds to TRP index associated with the first UCI (e.g., the first PUSCH and the first UCI correspond to the same TRP index), (iii) TRP group index associated with the first PUSCH corresponds to TRP group index associated with the first UCI (e.g., the first PUSCH and the first UCI correspond to the same TRP group index), (iv) first PUCCH (e.g., for the first UCI) and the first PUSCH are associated with a first joint/UL TCI state, and/or (v) first PUCCH and first PUSCH are associated with the same CORESET Chi Suoyin (e.g., coresetpoolndex).
In one embodiment, the UE selects the second PUSCH for multiplexing the second UCI based on: (i) SRS resource set indices associated with the second PUSCH correspond to SRS resource set indices associated with the second UCI (e.g., the second PUSCH and the second UCI correspond to the same SRS resource set index), (ii) TRP indices associated with the second PUSCH correspond to TRP indices associated with the second UCI (e.g., the second PUSCH and the second UCI correspond to the same TRP index), (iii) TRP group indices associated with the second PUSCH correspond to TRP group indices associated with the second UCI (e.g., the second PUSCH and the second UCI correspond to the same TRP group index), (iv) second PUCCH (e.g., for the second UCI) and the second PUSCH are associated with the second association/UL TCI state, and/or (v) second PUCCH and second PUSCH are associated with the same CORESET Chi Suoyin (e.g., coresetpoolndex).
In one embodiment, the UE selects a second PUSCH for multiplexing the second UCI. In an example, the second PUSCH transmitted on the first cell may include a second UCI (e.g., the second PUSCH transmitted on the first cell includes at least a portion of the second UCI). In some examples, the UE may multiplex at least a portion of the second UCI into the second PUSCH.
In one embodiment, the second PUSCH transmitted on the first cell does not include the first UCI (e.g., only the first PUSCH includes the first UCI).
In one embodiment, the second PUSCH transmitted on the first cell includes a first UCI.
In one embodiment, the second PUSCH transmitted on the first cell includes a second UCI.
In one embodiment, the UE receives an UL grant indicating a third PUSCH on the second cell. In some examples, the second PUCCH (e.g., for the second UCI) and the third PUSCH are associated with the same joint/UL TCI state (e.g., the 2 nd joint/UL TCI state). In some examples, the second PUCCH and the third PUSCH are associated with the same CORESET Chi Suoyin (e.g., coresetpoolndex). In some examples, the third PUSCH overlaps with the first UCI in the time domain. In some examples, the third PUSCH overlaps with the second UCI in the time domain. In some examples, the third PUSCH is in TTI.
In one embodiment, the UE transmits a third PUSCH including a second UCI on the second cell based on the second cell having a lower cell index than the first cell, wherein the UE is configured with a separate HARQ feedback mode. In some examples, the first PUSCH transmitted on the first cell does not include the second UCI and/or the second PUSCH transmitted on the first cell does not include the second UCI. For example, the UE may multiplex the second UCI into the third PUSCH.
In one embodiment, based on the UE being configured with a sdi mTRP or a mdi mTRP (e.g., based on whether the UE is configured with a sdi mTRP or a mdi mTRP and/or based on other information than whether the UE is configured with a sdi mTRP or a mdi mTRP), the UE performs one of the following PUSCH selection actions: (i) select a first PUSCH for multiplexing the first UCI and select a second PUSCH for multiplexing the second UCI, respectively, (ii) select a first PUSCH for multiplexing both the first UCI and the second UCI, or (iii) select both the first PUSCH and the second PUSCH for multiplexing both the first UCI and the second UCI. For example, based on whether the UE is configured with a sdi mTRP or a mdi mTRP, the UE may select a selection action (e.g., one selection action) from among PUSCH selection actions (e.g., based on whether the UE is configured with a sdi mTRP or a mdi mTRP and/or based on other information than whether the UE is configured with a sdi mTRP or a mdi mTRP).

In one embodiment, the UE selects a first PUSCH for multiplexing the first UCI and a second PUSCH for multiplexing the second UCI, respectively, based on the UE being configured with mci mTRP and: (i) the first PUCCH and the first PUSCH are associated with the same TCI state, (ii) the first PUCCH and the first PUSCH are associated with the same CORESET Chi Suoyin (e.g., coresetpooolindex), (iii) the second PUCCH and the second PUSCH are associated with the same TCI state, and/or (iv) the second PUCCH and the second PUSCH are associated with the same CORESET Chi Suoyin (e.g., coresetpooolindex).
In one embodiment, based on whether the UE is configured with a joint HARQ feedback mode or a separate HARQ feedback mode (e.g., based on whether the UE is configured with a joint HARQ feedback mode or a separate HARQ feedback mode and/or based on other information than whether the UE is configured with a joint HARQ feedback mode or a separate HARQ feedback mode), the UE performs one of the following PUSCH selection actions: (i) The first PUSCH is selected for multiplexing the first UCI and the second PUSCH is selected for multiplexing the second UCI, respectively, or (ii) the first PUSCH is selected for multiplexing both the first UCI and the second UCI. For example, the UE may select a selection action (e.g., one selection action) from among PUSCH selection actions based on whether the UE is configured with a joint HARQ feedback mode or a separate HARQ feedback mode (e.g., based on whether the UE is configured with a joint HARQ feedback mode or a separate HARQ feedback mode and/or based on other information than whether the UE is configured with a joint HARQ feedback mode or a separate HARQ feedback mode).
In one embodiment, the UE selects a first PUSCH for multiplexing both the first UCI and the second UCI based on the UE being configured with a joint HARQ feedback mode and: (i) a first SRS resource set index associated with the first PUSCH is lower than a second SRS resource set index associated with the second PUSCH, (ii) a first TRP index associated with the first PUSCH is lower than a second TRP index associated with the second PUSCH, (iii) a first TRP group index associated with the first PUSCH is lower than a second TRP group index associated with the second PUSCH, and/or (iv) a first CORESET pool index (e.g., coresetpoolndex) associated with the first PUSCH is lower than a second CORESET Chi Suoyin (e.g., coresetpoolndex) associated with the second PUSCH.

In one embodiment, the UE determines the selection function based on a UCI type of the first UCI. The UE selects a first PUSCH for multiplexing the first UCI according to the selection function.
In one embodiment, the UE determines whether the first UCI is (i) a first type of UCI including periodic CSI (e.g., periodic CSI report) and/or HARQ (e.g., HARQ information, such as HARQ feedback information), or (ii) a second type of UCI including aperiodic CSI (e.g., aperiodic CSI report) and/or semi-persistent CSI (e.g., semi-persistent CSI report). The UE determines the selection function based on whether the first UCI is a first type or a second type of UCI. The UE selects a first PUSCH for multiplexing the first UCI according to the selection function.
In one embodiment, a first PUSCH for multiplexing the first UCI is selected according to a selection function.
In some examples, the selection function includes a first selection function corresponding to selecting a first PUSCH for multiplexing a first UCI based on: (i) a first SRS resource set index associated with the first PUSCH is lower than a second SRS resource set index associated with the second PUSCH, (ii) a first TRP index associated with the first PUSCH is lower than a second TRP index associated with the second PUSCH, and/or (iii) a first TRP group index associated with the first PUSCH is lower than a second TRP group index associated with the second PUSCH.
In some examples, the selection function includes a second selection function corresponding to selecting the first PUSCH and the second PUSCH for multiplexing the first UCI. In an example in which the UE selects the first PUSCH and the second PUSCH for multiplexing the first UCI (e.g., according to the second selection function), the first PUSCH transmitted on the first cell may include at least a portion of the first UCI, and the second PUSCH transmitted on the first cell may include at least a portion of the first UCI. For example, the UE may multiplex at least a portion of the first UCI into the first PUSCH and at least a portion of the first UCI into the second PUSCH. In some examples, the UE may multiplex (i) all first UCI into the first PUSCH and (ii) all (same) first UCI into the second PUSCH. In some examples, the UE may (i) multiplex a first portion of the first UCI into the first PUSCH and (ii) multiplex the (same) first portion of the first UCI into the second PUSCH.
In some examples, the selection function includes a third selection function corresponding to selecting the first PUSCH for multiplexing the first UCI and/or selecting the second PUSCH for multiplexing the second UCI based on: (i) the first SRS resource set index associated with the first PUSCH corresponds to an SRS resource set index associated with the first UCI (e.g., the first PUSCH and the first UCI are associated with the same SRS resource set index), (ii) the first TRP index associated with the first UCI corresponds to a TRP index associated with the first UCI (e.g., the first PUSCH and the first UCI are associated with the same TRP index), (iii) the first TRP group index associated with the first PUSCH corresponds to a TRP group index associated with the first UCI (e.g., the first PUSCH and the first UCI are associated with the same TRP group index), and/or (iv) the first PUCCH (e.g., for the first UCI) is associated with the first joint/UL TCI state. In examples where the UE selects a first PUSCH for multiplexing the first UCI and/or selects a second PUSCH for multiplexing the second UCI (e.g., according to the third selection function), the first PUSCH transmitted on the first cell may include at least a portion of the first UCI, and the second PUSCH transmitted on the first cell may include at least a portion of the second UCI. For example, the UE may multiplex at least a portion of the first UCI into the first PUSCH and at least a portion of the second UCI into the second PUSCH.
In one embodiment, based on the UE being configured with a sdi mTRP (e.g., the UE may be configured with a configuration for performing a sdi mTRP transmission, e.g., performing a parallel transmission on multiple TRPs based on one DCI), the UE may select one or more PUSCHs (e.g., first PUSCHs) for multiplexing the first UCI (and/or the second UCI) using (and/or may be allowed to use) the first selection function, the second selection function, and/or the third selection function.
In one embodiment, based on the UE being configured with the joint HARQ feedback mode, the UE may use (and/or may be allowed to use) the first selection function, the second selection function, and/or the third selection function to select one or more PUSCHs (e.g., first PUSCHs) for multiplexing the first UCI (and/or the second UCI). In some examples, the joint HARQ feedback mode is associated with transmitting UCI for different TRPs in the same PUCCH or the same PUSCH. In some examples, when the UE is configured with a mdis mTRP with a joint HARQ feedback mode, the UE transmits UCI for different TRPs in the same PUCCH or the same PUSCH.
In one embodiment, the UE may use (and/or may be allowed to use) the first selection function, the second selection function, and/or the third selection function to select one or more PUSCHs (e.g., the first PUSCH) for multiplexing the first UCI (and/or the second UCI) based on (i) the UE being configured with a sdi mrp (e.g., the UE may be configured with a configuration for performing a sdi mrp transmission, e.g., performing parallel transmission on multiple TRPs based on one DCI), (ii) the first PUSCH and the second PUSCH being scheduled and/or configured by one DCI and/or one CG PUSCH configuration, (iii) the UE not being configured with a CORESET pool index (e.g., coresetpool index), (iv) the UE being configured with a TRP group index, and/or (v) the UE being configured with a joint HARQ feedback mode. In some examples, a sdi mTRP may be used for an ideal backhaul between two TRPs, where one DCI from one TRP (e.g., of the two TRPs) may be scheduled for transmission of the two TRPs (e.g., UL transmission). In some examples, the joint HARQ feedback mode is associated with transmitting UCI for different TRPs in the same PUCCH or the same PUSCH. In some examples, when the UE is configured with a mdis mTRP with a joint HARQ feedback mode, the UE transmits UCI for different TRPs in the same PUCCH or the same PUSCH.
In one embodiment, the UE may use (and/or may be allowed to use) a third selection function to select one or more PUSCHs (e.g., first PUSCH) for multiplexing the first UCI (and/or the second UCI) based on (i) the UE being configured with a mdis mTRP (e.g., the UE may be configured with a configuration for performing a mdis mTRP transmission), (ii) the first PUSCH being scheduled and/or configured by the first DCI and/or the first CG PUSCH configuration, and the second PUSCH being scheduled and/or configured by the second DCI (different from the first DCI) and/or the second CG PUSCH configuration (different from the first CG PUSCH configuration), and/or (iii) the UE being configured with a CORESET pool index (e.g., coresetpoolndex), and/or (iv) the UE being configured with a separate HARQ feedback mode. In some examples, a mdis mTRP may be used for a non-ideal backhaul between two TRPs, wherein each of the two TRPs is associated with a respective DCI and/or scheduling information, and/or wherein crossing TRPs is not allowed. In some examples, separate HARQ feedback modes are associated with transmitting UCI for different TRPs in different PUCCHs and/or different PUSCHs. In some examples, when the UE is configured with a mdis mTRP with separate HARQ feedback modes, the UE transmits UCI for different TRPs in different PUCCHs or different PUSCHs.
In one embodiment, based on the UE being configured with a mdis mTRP (e.g., the UE may be configured with a configuration for performing mdis mTRP transmissions), the UE may use (and/or may be allowed to use) a third selection function to select one or more PUSCHs (e.g., a first PUSCH) for multiplexing the first UCI (and/or the second UCI).
In one embodiment, based on the UE being configured with a separate HARQ feedback mode, the UE may use (and/or may be allowed to use) a third selection function to select one or more PUSCHs (e.g., first PUSCH) for multiplexing the first UCI (and/or the second UCI). In some examples, separate HARQ feedback modes are associated with transmitting UCI for different TRPs in different PUCCHs and/or different PUSCHs. In some examples, when the UE is configured with a mdis mTRP with separate HARQ feedback modes, the UE transmits UCI for different TRPs in different PUCCHs or different PUSCHs.
In an example, the UE may select one or more PUSCHs (e.g., first PUSCH) for multiplexing the first UCI (e.g., from the first PUSCH and the second PUSCH) in response to: (i) the UE is configured with a sdi mTRP (e.g., the UE may be configured with a configuration for performing a sdi mTRP transmission, e.g., performing parallel transmission on multiple TRPs based on one DCI), (ii) the first PUSCH and the second PUSCH are scheduled and/or configured by one DCI and/or one CG PUSCH configuration, (iii) the UE is not configured with a CORESET pool index (e.g., CORESET pool index), and/or (iv) the UE is configured with a TRP group index. In some examples, the UE may determine which selection function to use (from among a plurality of selection functions including, for example, a first selection function, a second selection function, a third selection function, and/or one or more other selection functions) based on whether the first UCI is a first type of UCI or a second type of UCI, and/or based on other information associated with the first UCI, the first PUSCH, and/or the second PUSCH.
In an example, the UE may use a first selection function (e.g., to select the one or more PUSCHs) based on a determination that the first UCI is a first type of UCI (and the UE is configured with sdi mTRP, for example). Alternatively and/or additionally, the UE may use a second selection function (e.g., to select the one or more PUSCHs) based on a determination that the first UCI is a first type of UCI (and the UE is configured with a sdi mTRP, for example). Alternatively and/or additionally, the UE may use a third selection function (e.g., to select the one or more PUSCHs) based on a determination that the first UCI is a first type of UCI. Alternatively and/or additionally, the UE may use the first selection function (e.g., to select the one or more PUSCHs) based on a determination that the first UCI is a second type of UCI (and the UE is configured with a sdi mTRP, for example). Alternatively and/or additionally, the UE may use a second selection function (e.g., to select the one or more PUSCHs) based on a determination that the first UCI is a second type of UCI (and the UE is configured with a sdi mTRP, for example). Alternatively and/or additionally, the UE may use a third selection function (e.g., to select the one or more PUSCHs) based on a determination that the first UCI is a second type of UCI.
In an example scenario in which the UE selects the one or more PUSCHs (e.g., first PUSCH) using a first selection function, the UE may select the first PUSCH for multiplexing the first UCI based on: (i) a first SRS resource set index associated with the first PUSCH is lower than a second SRS resource set index associated with the second PUSCH, (ii) a first TRP index associated with the first PUSCH is lower than a second TRP index associated with the second PUSCH, (iii) a first TRP group index associated with the first PUSCH is lower than a second TRP group index associated with the second PUSCH, and/or (iv) a first PUCCH (e.g., for a first UCI) is associated with a first joint/UL TCI state. In an example scenario, the UE may multiplex the first UCI (e.g., at least a portion of the first UCI) into the first PUSCH and/or transmit the first PUSCH including the first UCI on the first cell. In an example scenario, in some examples, the UE does not multiplex the first UCI into the second PUSCH (e.g., only selects the first PUSCH for multiplexing the first UCI, and/or does not select the second PUSCH for multiplexing the first UCI).
In an example scenario in which the UE selects the one or more PUSCHs (e.g., first PUSCH) using a second selection function, the UE may select both the first PUSCH and the second PUSCH for multiplexing the first UCI. In an example scenario, the UE may multiplex a first UCI (e.g., at least a portion of the first UCI) into a first PUSCH and may multiplex the first UCI (e.g., at least a portion of the first UCI) into a second PUSCH. In an example scenario, a UE may transmit (e.g., transmit in parallel) a first PUSCH including a first UCI and a second PUSCH including the first UCI on a first cell.
In an example scenario in which the UE selects the one or more PUSCHs (e.g., first PUSCH) using a third selection function, the UE may select the first PUSCH for multiplexing the first UCI and select the second PUSCH for multiplexing the second UCI based on: (i) the first SRS resource set index associated with the first PUSCH corresponds to an SRS resource set index associated with the first UCI (e.g., the first PUSCH and the first UCI are associated with the same SRS resource set index), (ii) the first TRP index associated with the first UCI corresponds to a TRP index associated with the first UCI (e.g., the first PUSCH and the first UCI are associated with the same TRP index), (iii) the first TRP group index associated with the first PUSCH corresponds to a TRP group index associated with the first UCI (e.g., the first PUSCH and the first UCI are associated with the same TRP group index), and/or (iv) the first PUCCH (e.g., for the first UCI) is associated with the first joint/UL TCI state. In an example scenario, the UE may multiplex a first UCI (e.g., at least a portion of the first UCI) into a first PUSCH and a second UCI (e.g., at least a portion of the second UCI) into a second PUSCH. In an example scenario, a UE may transmit a first PUSCH including a first UCI on a first cell and may transmit a second PUSCH including a second UCI on the first cell.
In one embodiment, a UE supports parallel uplink transmissions on a first cell via multiple UE panels. For example, the UE has the capability to transmit multiple uplink transmissions (e.g., PUSCH and/or PUCCH transmissions) in parallel on the first cell.
In one embodiment, the second PUSCH is transmitted on the first cell without multiplexing the first UCI (e.g., the second PUSCH may be transmitted on the first cell without multiplexing the first UCI into the second PUSCH). For example, based on the UE selecting only the first PUSCH for multiplexing the first UCI (and/or based on the UE not selecting the second PUSCH for multiplexing the first UCI, for example), the UE determines not to multiplex the first UCI into the second PUSCH. The second PUSCH transmitted on the first cell may not include the first UCI.
In one embodiment, the cell index of the first cell corresponds to a serving cell index (e.g., servCellIndex).
In one embodiment, the UE receives one or more second signals indicating a fourth PUSCH and a fifth PUSCH on the first cell in a second TTI, wherein a start symbol of the fourth PUSCH is earlier than a start symbol of the fifth PUSCH. The one or more second signals may include one or more second UL grants and/or one or more second configurations (e.g., indicating a fourth PUSCH and a fifth PUSCH on the first cell in the second TTI). In an example, the one or more signals may schedule and/or configure one or more resources (e.g., one or more time resources and/or one or more frequency resources) for the fourth PUSCH and/or the fifth PUSCH. In some examples, the fourth PUSCH at least partially overlaps with the fifth PUSCH. In some examples, the fourth PUSCH does not overlap with the fifth PUSCH. In some examples, the UE determines to transmit a third UCI in the second TTI (and, e.g., on the first cell), wherein the third UCI overlaps (e.g., at least partially overlaps) with the fourth PUSCH and the fifth PUSCH in the time domain.
In one embodiment, the UE selects the fourth PUSCH to include (and/or multiplex) the third UCI based on the UE being configured with a joint HARQ feedback mode and the fourth PUSCH being earlier than the fifth PUSCH. In some examples, the UE transmits a fourth PUSCH and a fifth PUSCH on the first cell, wherein the fourth PUSCH transmitted on the first cell includes a third UCI (e.g., only the fourth PUSCH includes the third UCI) and the fifth PUSCH transmitted on the first cell does not include the third UCI.
In one embodiment, the UE selects the fifth PUSCH includes (and/or multiplexes) the third UCI based on the UE being configured with a separate HARQ feedback mode and: (i) The third PUCCH and the fifth PUSCH are associated with the same TCI state, wherein the third PUCCH is associated with a third UCI, and/or (ii) the third PUCCH and the fifth PUSCH are associated with the same CORESET Chi Suoyin (e.g., coresetpoolndex). In some examples, the UE transmits a fourth PUSCH and a fifth PUSCH on the first cell, wherein the fifth PUSCH transmitted on the first cell includes the third UCI (e.g., only the fifth PUSCH includes the third UCI), and the fourth PUSCH transmitted on the first cell does not include the third UCI.
In one embodiment, the selection function includes a rule.
In the present disclosure, an example in which a channel (e.g., PUSCH) is selected for multiplexing UCI may be supplemented with a channel selected to include (e.g., carry) UCI. For example, selecting the first PUSCH with the UE may include (e.g., carry) the first UCI to supplement (and/or replace) selecting the first PUSCH by the UE for multiplexing the first UCI (e.g., in step 1415 of fig. 14) (e.g., the first PUSCH may be selected for transmitting the first UCI on the first cell, e.g., by inserting the first UCI into the first PUSCH and/or transmitting the first PUSCH including the first UCI on the first cell, wherein the first UCI may be inserted into the first PUSCH via multiplexing the first UCI into the first PUSCH).
