Wireless communication systems are widely deployed to provide various telecommunications services, such as telephony, video, data, messaging, broadcasting or other similar types of services. These wireless communication systems may employ multiple access technologies that can support communications with multiple users by sharing available wireless communication system resources with those users.

Although wireless communication systems have made tremendous technological advances over the years, challenges remain. For example, complex and dynamic environments can still attenuate or block signals between wireless transmitters and wireless receivers. Therefore, there is a constant desire to improve the technical performance of wireless communication systems, including: increasing communication speed and data carrying capacity, improving the efficiency of shared communication media, reducing the power used by transmitters and receivers when performing communications, and improving the efficiency of wireless communications. Reliability, avoid redundant transmission and/or reception and related processing, improve the coverage of wireless communication, increase the number and types of devices that can access the wireless communication system, increase the ability of different types of devices to communicate with each other, and increase the availability The number and type of wireless communication media, etc. Accordingly, there is a need for further improvements in wireless communication systems to overcome the above technical challenges and other challenges.

In one aspect, a method for wireless communications performed by a user equipment (UE) includes receiving a downlink control information (DCI) message scheduling a plurality of transmissions in a plurality of different time slots, wherein : The first transmission set in the first time slot set in the plurality of different time slots in the plurality of transmissions conflicts with the corresponding second transmission set previously scheduled in the first time slot set, the DCI The message includes at least a first field, the first field includes a first plurality of values, each different value of the first plurality of values corresponds to a different transmission in the plurality of transmissions, and the first group a number of values in the plurality of values equals a number of transmissions in the plurality of transmissions; and, transmitting a third set of transmissions in the plurality of transmissions, the third set of transmissions being the same as those previously scheduled within the first set of time slots The second set of transmissions does not conflict.

In one aspect, a method performed by a network entity includes sending a downlink control information (DCI) message that schedules a plurality of transmissions in a plurality of different time slots, wherein: A first transmission set in a first time slot set in a plurality of different time slots conflicts with a corresponding second transmission set previously scheduled in the first time slot set, and the DCI message at least includes a first field, A field includes a first plurality of values, each different value of the first plurality of values corresponding to a different one of the plurality of transmissions, and a number of values in the first plurality of values is equal to the a number of transmissions in the plurality of transmissions; and transmitting a third transmission set of the plurality of transmissions that does not conflict with the second transmission set previously scheduled within the first time slot set.

Other aspects provide: an apparatus operable, configured, or otherwise adapted to perform any one or more of the foregoing methods and/or methods described elsewhere herein; a transitory computer-readable medium that contains instructions that, when executed by a processor of a device, cause the device to perform the methods described above and those described elsewhere herein; a computer program product embodied on a computer-readable storage medium, Comprised of code for performing the methods described above and those described elsewhere herein; and/or an apparatus comprising means for performing the methods described above and those described elsewhere herein. For example, an apparatus may include a processing system, a device having a processing system, or a processing system coordinated via one or more networks.

For purposes of illustration, the following description and drawings set forth certain features.

A single DCI can schedule multiple PxSCHs. As described herein, PxSCH is used to represent both the Physical Downlink Shared Channel (PDSCH) and the Physical Uplink Shared Channel (PUSCH). Aspects of the subject matter provide apparatus, methods, processing systems, and computer-readable media for multiple PxSCH DCIs that signal a new data indication (NDI) for each scheduled PxSCH and/or redundant version (RV), regardless of whether PxSCH is valid. A PxSCH may be considered valid when it conflicts in time with a previously scheduled semi-static uplink/downlink transmission. In some cases, the number of bits of NDI signaled in the multi-PxSCH DCI may correspond to the number of PxSCHs (eg, PDSCH or PUSCH) scheduled by the multi-PxSCH DCI. Similarly, the number of bits of RV signaled in the multi-PxSCH DCI may correspond to the number of PxSCHs (eg, PDSCH or PUSCH) scheduled by the multi-PxSCH DCI. Introduction to wireless communication networks

The techniques and methods described in this article can be used in various wireless communication networks. Although terminology commonly associated with 3G, 4G and/or 5G wireless technologies may be used to describe aspects herein, aspects described in this document may also apply to other communications systems and standards not expressly mentioned herein.

Figure 1 illustrates an example of a wireless communications system 100 in which aspects described herein may be implemented.

Generally, wireless communication network 100 includes various network entities (alternatively, network elements or network nodes). Network entities are usually communication equipment and/or communication functions performed by communication equipment (for example, user equipment (UE), base station (BS), components of the BS, servers, etc.). For example, various functions of the network and various devices associated with and interacting with the network may be considered network entities. Additionally, wireless communications network 100 includes terrestrial aspects, such as terrestrial-based network entities (eg, BS 102), as well as non-terrestrial aspects, such as satellites 140 and aircraft 145, which may include devices capable of communicating with other network elements (eg, The airborne network entity (e.g., one or more BSs)) that communicates with user equipment on the ground.

In the illustrated example, wireless communication network 100 includes BS 102, UE 104, and one or more core networks, such as Evolved Packet Core (EPC) 160 and 5G Core (5GC) network 190, which interact Operates to provide communications services over a variety of communications links, including wired and wireless links.

Figure 1 illustrates various example UEs 104, which may more generally include: cellular phones, smart phones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radio units, global positioning Systems, multimedia devices, video equipment, digital audio players, cameras, game consoles, tablet devices, smart devices, wearable devices, vehicles, electricity meters, gas pumps, large or small kitchen appliances, medical equipment, implants, sensing actuators/actuators, displays, Internet of Things (IoT) devices, always-on (AON) devices, edge processing devices, or other similar devices. The UE 104 may also be more commonly referred to as a mobile device, wireless device, wireless communications device, station, mobile station, subscriber station, mobile subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, remote device, access Terminals, mobile terminals, wireless terminals, remote terminals, mobile phones, etc.

BS 102 wirelessly communicates with UE 104 via communication link 120 (eg, sends signals to and receives signals from UE 104). Communication link 120 between BS 102 and UE 104 may include uplink (UL) (also referred to as reverse link) transmissions from UE 104 to BS 102 and/or downlink from BS 102 to UE 104 road (DL) (also called forward link) transmission. Communication link 120 may use multiple-input multiple-output (MIMO) antenna technology, which in various aspects includes spatial multiplexing, beamforming, and/or transmit diversity.

The BS 102 may generally include: Node B, enhanced Node B (eNB), next generation enhanced Node B (ng-eNB), next generation Node B (gNB or gNodeB), access point, base station transceiver, radio base stations, radio transceivers, transceiver functional units, transmitting and receiving points, etc. Each of the BSs 102 may provide communications coverage for a corresponding geographic coverage area 110 , which may sometimes be referred to as a cell and which may overlap in some cases (e.g., a small cell 102 ′ may have a coverage area 110 ′ that Overlaps the coverage area 110 of macrocells). For example, the BS may target macrocells (covering a relatively large geographic area), picocells (covering a relatively small geographic area, such as a stadium), femtocells (relatively small geographic ranges (e.g., residences)), and/or or other types of cells to provide communication coverage.

Although BS 102 is illustrated in various aspects as a single communications device, BS 102 may be implemented in various configurations. For example, one or more components of a base station can be decomposed, including a central unit (CU), one or more distributed units (DU), one or more radio units (RU), near-real-time (near-RT) RAN intelligence Controller (RIC) or non-real-time (non-RT) RIC, to name a few examples. In another example, various aspects of the base station can be virtualized. More generally, a base station (eg, BS 102) may include components located at a single physical location or components located at various physical locations. In instances where the base station includes components located at various physical locations, the various components may each perform a function such that the various components collectively perform functions similar to those of a base station located at a single physical location. In some aspects, a base station including components located at various physical locations may be referred to as a disaggregated radio access network architecture, such as an open RAN (O-RAN) or virtualized RAN (VRAN) architecture. Figure 2 illustrates and describes an example decomposed base station architecture.

Different BSs 102 within the wireless communication network 100 may also be configured to support different radio access technologies, such as 3G, 4G and/or 5G. For example, a BS 102 configured for 4G LTE, collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN), may communicate via a first backhaul link 132 (e.g., an S1 interface ) to interface with EPC 160. A BS 102 configured for 5G (eg, 5G NR or Next Generation RAN (NG-RAN)) may interface with the 5GC 190 via a second backhaul link 184 . BSs 102 may communicate with each other directly or indirectly (eg, via EPC 160 or 5GC 190) over a third backhaul link 134 (eg, an X2 interface), which may be wired or wireless.

Wireless communications network 100 may subdivide the electromagnetic spectrum into various categories, frequency bands, channels, or other characteristics. In some aspects, this subdivision is provided based on wavelength and frequency, where frequencies may also be referred to as carriers, subcarriers, frequency channels, tones, or subbands. For example, 3GPP currently defines frequency range 1 (FR1) to include 410 MHz–7125 MHz, which is often (interchangeably) referred to as “sub-6 GHz”. Similarly, 3GPP currently defines Frequency Range 2 (FR2) to include 24,250 MHz–52,600 MHz, which is sometimes (interchangeably) referred to as “millimeter wave” (“mmW” or “mmWave”) . Base stations configured to communicate using mmWave/near mmWave radio frequency bands (eg, mmWave base stations such as BS 180) may utilize beamforming (eg, 182) with UEs (eg, 104) to improve path loss and range.

The communication link 120 between the BS 102 and, for example, the UE 104 may be via one or more carriers, which may have different bandwidths (e.g., 5, 10, 15, 20, 100, 400, and/or other MHz) , and it can be aggregated in various aspects. The carriers may be adjacent to each other or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (eg, more or fewer carriers may be allocated for DL than for UL).

Communication using higher frequency bands can have higher path loss and shorter distances than lower frequency communication. Therefore, certain base stations (eg, 180 in Figure 1) may utilize beamforming 182 with the UE 104 to improve path loss and distance. For example, BS 180 and UE 104 may each include a plurality of antennas (such as antenna elements, antenna panels, and/or antenna arrays) to facilitate beamforming. In some cases, BS 180 may transmit beamformed signals to UE 104 in one or more transmission directions 182'. UE 104 may receive beamformed signals from BS 180 in one or more receive directions 182''. UE 104 may also transmit beamformed signals to BS 180 in one or more transmission directions 182''. BS 180 may receive beamformed signals from UE 104 in one or more receive directions 182'. Subsequently, BS 180 and UE 104 may perform beam training to determine the best reception and transmission directions for each of BS 180 and UE 104. Note that the transmit direction and receive direction for BS 180 may be the same or may be different. Similarly, the transmit direction and receive direction for UE 104 may be the same or may be different.

The wireless communication system 100 also includes a Wi-Fi AP 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154 in, for example, the 2.4 GHz and/or 5 GHz unlicensed spectrum.

Certain UEs 104 may communicate with each other using device-to-device (D2D) communication links 158 . The D2D communication link 158 may use one or more sidelink channels, such as physical sidelink broadcast channel (PSBCH), physical sidelink discovery channel (PSDCH), physical sidelink shared channel (PSSCH) , Physical Sidelink Control Channel (PSCCH) and/or Physical Sidelink Feedback Channel (PSFCH).

The EPC 160 may include various functional components, including: a mobility management entity (MME) 162, other MMEs 164, a service gateway 166, a multimedia broadcast multicast service (MBMS) gateway 168, and a broadcast multicast service center (BM-SC). 170 and/or Packet Data Network (PDN) gateway 172, such as in the illustrated example. MME 162 can communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160 . Typically, MME 162 provides bearer and connection management.

Typically, user Internet Protocol (IP) packets are transmitted via a service gateway 166, which itself is connected to the PDN gateway 172. PDN gateway 172 provides IP address allocation and other functions to UEs. PDN gateway 172 and BM-SC 170 connect to IP services 176, which may include, for example, the Internet, intranet, IP Multimedia Subsystem (IMS), Packet Switched (PS) streaming services, and/or other IP service.

BM-SC 170 can provide functions for MBMS user service configuration and delivery. BM-SC 170 may act as an entry point for content provider MBMS transmissions, may be used to authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and/or may be used to schedule MBMS transmissions. The MBMS gateway 168 may be used to distribute MBMS traffic to BSs 102 belonging to a Multicast Broadcast Single Frequency Network (MBSFN) area broadcasting a specific service, and/or may be responsible for communication period management (start/stop) and collection Billing information related to eMBMS.

5GC 190 may include various functional components, including: access and mobility management function (AMF) 192, other AMF 193, session management function (SMF) 194, and user plane function (UPF) 195. AMF 192 may communicate with Unified Data Management (UDM) 196.

AMF 192 is the control node that handles signaling between UE 104 and 5GC 190. For example, AMF 192 provides quality of service (QoS) flow and communication period management.

Internet Protocol (IP) packets are transmitted via the UPF 195, which connects to the IP service 197 and provides IP address allocation to the UE and other functions for the 5GC 190. IP services 197 may include, for example, the Internet, intranet, IMS, PS streaming services, and/or other IP services.

In various aspects, network entities or network nodes may be implemented as aggregated base stations, disaggregated base stations, components of base stations, integrated access and backhaul (IAB) nodes, relay nodes, sidelinks Road nodes, to give a few examples.

Figure 2 illustrates an example disaggregated base station 200 architecture. The disaggregated base station 200 architecture may include one or more central units (CUs) 210 that may communicate directly with the core network 220 via a backhaul link, or via one or more disaggregated base station units (such as via an E2 link A near-real-time (near-RT) RAN Intelligent Controller (RIC) 225, or a non-real-time (non-RT) RIC 215 associated with the Service Management and Orchestration (SMO) framework 205, or both) indirectly connected to the core network 220 Communication. CU 210 may communicate with one or more distributed units (DUs) 230 via corresponding mid-range links (such as an F1 interface). DU 230 may communicate with one or more radio units (RU) 240 via corresponding fronthaul links. RU 240 may communicate with corresponding UE 104 via one or more radio frequency (RF) access links. In some implementations, UE 104 may be served by multiple RUs 240 simultaneously.

Each of these units (eg, CU 210, DU 230, RU 240) and near-RT RIC 225, non-RT RIC 215, and SMO framework 205 may include or be coupled to one or more interfaces that One or more interfaces are configured to receive or send signals, data, or information (collectively, signals) via wired or wireless transmission media. Each of these units, or an associated processor or controller that provides instructions to the communication interface of the units, may be configured to communicate with one or more of the other units via the transmission medium. For example, the units may include a wired interface configured to receive signals over a wired transmission medium or to send signals to one or more of the other units. Additionally or alternatively, these units may include a wireless interface (which may include a receiver, transmitter, or transceiver (such as a radio frequency (RF) transceiver)) configured to receive signals over a wireless transmission medium or to transmit signals to other units. One or more units send signals or both.

In some aspects, CU 210 may host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Service Data Adaptation Protocol (SDAP), etc. Each control function may be implemented using an interface configured to communicate with other control functions hosted by CU 210. CU 210 may be configured to handle user plane functions (eg, Central Unit-User Plane (CU-UP)), control plane functions (eg, Central Unit-Control Plane (CU-CP)), or a combination thereof. In some implementations, CU 210 may be logically divided into one or more CU-UP units and one or more CU-CP units. The CU-UP unit may communicate bi-directionally with the CU-CP unit via an interface, such as the El interface when implemented in an O-RAN configuration. CU 210 may be implemented to communicate with DU 230 as needed for network control and signaling.

DU 230 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 240. In some aspects, depending at least in part on functional partitioning, such as those defined by the 3rd Generation Partnership Project (3GPP), DU 230 may host one or more of the following: Radio link control (RLC) layer, media access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. group). In some aspects, DU 230 may also host one or more lower PHY layers. Each layer (or module) may be implemented using an interface configured to communicate with other layers (and modules) hosted by DU 230 or with control functions hosted by CU 210 .

Lower layer functions may be implemented by one or more RUs 240. In some deployments, based at least in part on functional partitioning (such as lower layer functional partitioning), RU 240 controlled by DU 230 may correspond to a logical node hosting RF processing functions, or low PHY layer functions (such as executing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, Physical Random Access Channel (PRACH) extraction and filtering, etc.) or both. In such an architecture, RU 240 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104 . In some implementations, the real-time and non-real-time aspects of control and user plane communications with the RU 240 may be controlled by the corresponding DU 230. In some scenarios, this configuration may enable DU 230 and CU 210 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

The SMO framework 205 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network components. For non-virtualized network components, the SMO framework 205 may be configured to support deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operations and maintenance interface (such as the O1 interface). For virtualized network components, the SMO framework 205 may be configured to interact with a cloud computing platform (such as the Open Cloud (O-Cloud) 290) via a cloud computing platform interface (such as the O2 interface) to perform network component lifecycle management (such as generating physical virtualized network components). Such virtualized network components may include, but are not limited to, CU 210, DU 230, RU 240, and near RT RIC 225. In some implementations, the SMO framework 205 may communicate with a hardware aspect of the 4G RAN, such as an open eNB (O-eNB) 211, via an O1 interface. Additionally, in some implementations, the SMO framework 205 may communicate directly with one or more RUs 240 via the O1 interface. The SMO framework 205 may also include a non-RT RIC 215 configured to support the functionality of the SMO framework 205 .

The non-RT RIC 215 may be configured to include logic functions that enable non-real-time control and optimization of RAN components and resources, artificial intelligence/machine learning (AI/ML) workflows (including model training and updates) Strategy-based instruction in applications/characteristics of or near RT RIC 225. Non-RT RIC 215 may couple to or communicate with near-RT RIC 225 (such as via the A1 interface). Near RT RIC 225 may be configured to include logic that interfaces one or more CUs 210, one or more DUs 230, or both, and O-eNBs with near RT RIC 225, such as via E2 Interface) to achieve near-real-time control and optimization of RAN components and resources through data collection and actions.

In some implementations, the non-RT RIC 215 may receive parameters or external rich information from an external server in order to generate AI/ML models to be deployed in the near-RT RIC 225. Such information may be utilized by the near RT RIC 225 and may be received at the SMO framework 205 or non-RT RIC 215 from non-network sources or from network functions. In some examples, non-RT RIC 215 or near-RT RIC 225 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 215 may monitor long-term trends and patterns for performance and employ AI/ML models to perform corrective actions via the SMO framework 205 (such as via reconfiguration of O1) or via establishing RAN management policies (such as A1 policies) Perform corrective actions.

The modulator (MOD) provides an output symbol stream. The modulator of each of transceivers 332a-332t may process the respective output symbol stream to obtain an output sample stream. Each modulator can further process (eg, convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. Downlink signals from modulators in transceivers 332a-332t may be sent via antennas 334a-334t, respectively.

To receive downlink transmissions, UE 104 includes antennas 352a-352r that can receive downlink signals from BS 102 and that can provide received signals to demodulators (DEMODs) in transceivers 354a-354r, respectively.

Wireless communication systems may utilize Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on both the uplink and downlink. Such systems can also support half-duplex operation using time-division duplex (TDD). OFDM and single-carrier frequency division multiplexing (SC-FDM) divide the system bandwidth (eg, as illustrated in Figures 4B and 4D) into multiple orthogonal subcarriers. Data can be used to modulate each subcarrier. Modulation symbols are transmitted using OFDM in the frequency domain and/or SC-FDM in the time domain.

The wireless communication frame structure may be Frequency Division Duplex (FDD), where for a specific set of subcarriers, the subframes within the set of subcarriers are dedicated to DL or UL. The wireless communication frame structure may also be Time Division Duplex (TDD), where for a specific set of subcarriers, subframes within the set of subcarriers are dedicated to both DL and UL.

In Figure 4A and Figure 4C, the wireless communication frame structure is TDD, where D is DL, U is UL, and X is flexibly used between DL/UL. The UE can be configured into the slot format via a received slot format indicator (SFI) (dynamically via DL Control Information (DCI) or semi-statically/statically via Radio Resource Control (RRC) signaling) . In the example shown, the 10 ms frame can be divided into 10 equally sized 1 ms sub-frames. Each subframe may include one or more time slots. In some instances, each time slot may include 7 or 14 symbols, depending on the time slot format. A subframe may also include mini-slots, which may typically have fewer time slots than the entire time slot. Other wireless communication technologies may have different frame structures and/or different channels.

In some aspects, the number of time slots within a subframe may be based on time slot configuration and numerology. For example, for slot configuration 0, the different numbering schemes (µ) 0 to 5 allow 1, 2, 4, 8, 16 and 32 slots per subframe respectively. For slot configuration 1, the different numbering schemes 0 to 2 allow 2, 4 and 8 slots per subframe respectively. Correspondingly, for slot configuration 0 and number scheme µ, there are 14 symbols/slot and 2µ slots/subframe. Subcarrier spacing and symbol length/duration are functions of the digital scheme. The subcarrier spacing can be equal to kHz, where μ is the numerical scheme 0 to 5. Therefore, the digital scheme µ=0 has a subcarrier spacing of 15 kHz, and the digital scheme µ=5 has a subcarrier spacing of 480 kHz. Symbol length/duration is inversely related to subcarrier spacing. Figures 4A, 4B, 4C and 4D provide examples of slot configuration 0 with 14 symbols per slot and digital scheme µ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 µs.

As illustrated in Figures 4A, 4B, 4C, and 4D, a resource grid may be used to represent the frame structure. Each slot includes a resource block (RB) (also known as physical RB (PRB)), which extends, for example, to 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

As shown in Figure 4A, some of the REs carry reference (preamble) signals (RS) for UEs (eg, UE 104 of Figures 1 and 3). The RS may include demodulation RS (DMRS) and/or channel status information reference signal (CSI-RS) for channel estimation at the UE. RS may also include beam measurement RS (BRS), beam refinement RS (BRRS) and/or phase tracking RS (PT-RS).

Figure 4B illustrates examples of various DL channels within sub-frames of a frame. The Physical Downlink Control Channel (PDCCH) carries DCI within one or more Control Channel Elements (CCEs), each CCE includes, for example, nine RE Groups (REGs), each REG includes, for example, four consecutive REGs in an OFDM symbol. RE.

The Primary Synchronization Signal (PSS) can be within symbol 2 of a specific subframe of the frame. The PSS is used by the UE 104 (eg, 104 of Figures 1 and 3) to determine subframe/symbol timing and physical layer identification.

The secondary synchronization signal (SSS) may be within symbol 4 of a specific subframe of the frame. SSS is used by the UE to determine the physical layer cell identity group number and wireless telecommunications frame timing.

Based on the physical layer identifier and the physical layer cell identifier group number, the UE can determine the physical cell identifier (PCI). Based on PCI, the UE can determine the location of the aforementioned DMRS. The Physical Broadcast Channel (PBCH) (which carries the Master Information Block (MIB)) can be logically grouped together with the PSS and SSS packets to form the Synchronization Signal (SS)/PBCH block. The MIB provides the number of RBs in the system bandwidth and the system frame number (SFN). The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information (such as System Information Block (SIB)) and/or paging messages that are not sent via the PBCH.

As shown in Figure 4C, some of the REs carry DMRS for channel estimation at the base station (indicated as R for one particular configuration, but other DMRS configurations are possible). The UE may send DMRS for PUCCH and DMRS for PUSCH. PUSCH DMRS may be sent, for example, in the first one or two symbols of PUSCH. PUCCH DMRS may be sent in different configurations depending on whether short or long PUCCH is sent and depending on the specific PUCCH format used. The UE 104 may send a sounding reference signal (SRS). The SRS may be sent, for example, in the last symbol of the subframe. The SRS may have a comb structure, and the UE may send the SRS on one of these combs. SRS can be used by base stations for channel quality estimation to enable frequency-based scheduling on UL.

Figure 4D illustrates examples of various UL channels within subframes of a frame. The PUCCH may be located as indicated in one configuration. PUCCH carries uplink control information (UCI), such as scheduling request, channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI) and HARQ ACK/NACK feedback. PUSCH carries data and may additionally be used to carry Buffer Status Report (BSR), Power Headroom Report (PHR) and/or UCI. Aspects related to NDI and RV for invalid PxSCH in multi-PxSCH grant

Current protocols support multiple downlink (DL) or multiple uplink (UL) resource configurations via a single downlink control information (DCI) message. These multi-DL or multi-UL transmissions are often referred to as multi-PxSCH transmissions, where PxSCH stands for Physical Downlink Shared Channel (PDSCH) or Physical Uplink Shared Channel (PUSCH). In some cases, the multi-PxSCH schedule DCI includes at least the following fields: Time Domain Resource Allocation (TDRA) field, Modulation and Coding Scheme (MCS), New Data Indicator (NDI), Redundancy Version (RV), and Hybrid Automatic repeat request (HARQ) procedure number. In some cases, in the context of a PDSCH transmission, the scheduled DCI may include the corresponding MCS, NDI, and RV for each transport block (TB) of the PDSCH transmission.

The TDRA field indicates time domain resources for multiple PxSCHs (eg, multiple PDSCHs or multiple PUSCHs). In some cases, multiple scheduled PxSCHs may be implicitly indicated to the UE via multiple valid separate start and length indicator vectors (SLIVs). In one example, the TDRA includes an index value pointing to an index in the TDRA table. In one example, the TDRA index value is between 0-15. In some cases, the row corresponding to the TDRA index value indicates a single SLIV or multiple SLIVs. Each scheduled PxSCH may have a separate SLIV per time domain resource.

In one example, for a DCI that schedules multiple PDSCHs, the modulation and coding scheme (MCS) for the first TB appears only once in the DCI and may be applicable to the first TB in each scheduled PDSCH. . Additionally, in some cases, the NDI for the first TB may be signaled per PDSCH and apply to the first TB of each PDSCH. The NDI may indicate whether the PDSCH is used for new transmissions or retransmissions.

The RV for the first TB may be signaled per PDSCH. In some cases, when only a single PDSCH is scheduled, two bits may be used to signal the RV, otherwise one bit per PDSCH may be used to signal the RV. The RV for the first TB may be applicable to the first TB of each scheduled PDSCH. In one example, RV can be set not to change during the HARQ procedure.

The HARQ procedure number represents a unique identification code for each HARQ procedure. The HARQ procedure number signaled in DCI may be applied to the first scheduled PDSCH and incremented by one for subsequent PDSCHs (eg, using modulo arithmetic if necessary).

Although the above technology refers to a specific instance in which PxSCH is a PDSCH, in some cases, the PxSCH may be a PUSCH. In such cases, the fields of the multi-PUSCH DCI include the MCS for the PUSCH TB, the NDI for the TB, the RV for the TB, and the HARQ procedure number, where these fields correspond to the PUSCH transmission.

As mentioned above, DCI can schedule multiple PDSCH or PUSCH. Some instances of scheduled PDSCH or PUSCH may overlap in time with previously scheduled transmissions. When PDSCHs are scheduled simultaneously with UL transmissions, overlapping PDSCHs may be considered invalid and may be discarded. Similarly, when PUSCH is scheduled simultaneously with DL transmission, PUSCH may be considered invalid and may be abandoned. Currently, it has been agreed that if the scheduled PDSCH or PUSCH is abandoned due to conflict with the previously scheduled UL or DL symbols respectively, then for the dropped/discarded (or invalid) PDSCH/PUSCH, incrementing the HARQ procedure number may be skipped and applied only to valid (e.g., non-overlapping) PDSCH/PUSCH transmissions. In one example, the scheduled PDSCH/PUSCH may be indicated by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated .

In view of this agreement, and with reference to the DCI fields above, the HARQ procedure ID may be signaled in the multi-PDSCH scheduled DCI for the PDSCH TBs scheduled by the multi-PDSCH DCI, and may only be used for valid PDSCHs (e.g., with semi-static UL It is incremented by transmitting PDSCHs that do not collide or overlap in time). Similar rules apply for multi-PUSCH DCI. For example, the HARQ procedure ID may be signaled in the multi-PUSCH DCI for the first PUSCH scheduled by the multi-PUSCH DCI, and may only be for valid PUSCHs (e.g., PUSCHs that do not conflict or overlap in time with DL transmissions) Increment it.

Although it is possible to agree on the HARQ procedure (for example, increment the HARQ procedure ID number only for valid PUSCH/PDSCH), it is not clear how to handle the signaling of NDI and RV in the case of invalid PDSCH or PUSCH, which may lead to some negative impact. For example, when an invalid PDSCH or PUSCH occurs, the PDSCH or PUSCH may be discarded from transmission. In this case, if the NDI or RV for the remaining PDSCH or PUSCH transmission (e.g., multi-PDSCH transmission or multi-PUSCH transmission) is not properly signaled, this may result in the remaining PDSCH or PUSCH not being correctly received or decoded. PUSCH transmission, thereby wasting time and frequency resources used for communication within the wireless network (eg, the wireless communication network 100 of FIG. 1 ). In such cases, the PDSCH or PUSCH transmission may need to be retransmitted, which may unnecessarily consume additional time and frequency resources for communications within the wireless network, as well as additional power resources at the device performing the retransmission.

Accordingly, aspects of this disclosure provide techniques for signaling NDI and/or RV for PxSCH transmissions scheduled by multiple PxSCH grants. In some cases, these techniques can be used to signal NDI and/or RV regardless of whether the corresponding PxSCH is valid or invalid. In some cases, the techniques described herein may help avoid scenarios where NDI and/or RV associated with PxSCH are inappropriately signaled, thereby reducing inappropriately received/decoded transmissions. By reducing improperly received/decoded transmissions due to improperly signaled NDI and/or RV, time and frequency resources within the wireless network can be saved (e.g., not wasted) and time and frequency resources within the wireless network can be saved. The power resources of the device.

Accordingly, in some cases, a network entity (e.g., BS 102 shown in FIGS. 1 and 3 and/or a disaggregated base station as described with respect to FIG. 2) may provide a signal to a UE (e.g., in FIGS. The UE 104 shown in ) sends a DCI, which may include or signal the NDI and/or RV per PxSCH scheduled by the DCI. In other words, NDI and RV can be signaled as per the SLIV indicated by the DCI. Regardless of whether PxSCH is valid or not, the DCI may include a corresponding single NDI bit and a corresponding single RV bit for each scheduled PxSCH/SLIV. In some cases, the corresponding NDI bits for each scheduled PxSCH/SLIV may be included in the NDI field within the DCI. In other words, the NDI field may include a plurality of NDI bits, and each different NDI bit corresponds to a different scheduled PxSCH/SLIV. Similarly, the corresponding RV bits for each scheduled PxSCH/SLIV may be included in the RV field within the DCI. In other words, the RV field may include a plurality of RV bits, and each different RV bit corresponds to a different scheduled PxSCH/SLIV.

In some cases, when PDSCH is abandoned due to overlap with semi-static UL symbols, or when PUSCH is abandoned due to overlap with previously scheduled DL symbols, the UE may ignore the discarded ( For example, invalid) PxSCH transmission corresponds to the corresponding NDI bits and the corresponding RV bits. In some cases, a single corresponding NDI bit and a single corresponding RV bit corresponding to each scheduled PxSCH may be an efficient way for the UE to combine each NDI bit and RV bit. Efficient way of associating elements with PxSCH/SLIV, deciding which PxSCHs/SLIV are valid and/or invalid, and ignoring NDI bits and RV bits in the DCI corresponding to invalid PxSCHs/SLIV.

As mentioned, in some cases, the UE may decide whether the PxSCH is valid or invalid based on the DCI received from the network node. In one example, for a multi-PDSCH grant (e.g., DCI schedules multiple PDSCHs), the UE may decide to use the time slot offset corresponding to one or more SLIVs in the scheduled PDSCH (e.g., as determined by the DCI). and whether there is temporal overlap between one or more TDRAs (eg, k0 for PDSCH and k2 for PUSCH) and semi-static UL transmissions. In one example, overlapping in time indicates that scheduled PDSCH transmissions overlap, collide, or conflict with UL transmissions. Similarly, for a multiple PUSCH grant, overlap in time between a scheduled PUSCH transmission and a previously scheduled DL transmission indicates that the scheduled PUSCH transmission overlaps, collides, or conflicts with the previously scheduled DL transmission.

In some cases, to help determine which NDI bits and RV bits to ignore in the DCI when certain scheduled PxSCH transmissions are invalid, the NDI bits in the NDI field and the RV in the RV field The bits can be ordered according to different instances, such as instance 1 and instance 2 described below.

Example 1 : In some cases, the position of the NDI bit in the NDI field in the DCI (e.g., sorting) and the position of the RV bit in the RV field of the DCI correspond to (e.g., scheduled in the DCI PxSCH) SLIV order in the time domain, regardless of whether the SLIV or corresponding PxSCH is valid or invalid. Therefore, in order to decide which NDI bits and RV bits are invalid and therefore can be ignored, the UE may first decide which PxSCH bits are invalid (eg, overlap with another transmission). Thereafter, since the position of the bits in the NDI field and the position of the bits in the RV field correspond to the order of the SLIVs of the scheduled PxSCHs in the DCI, the UE can subsequently base on the SLIVs corresponding to these invalid PxSCHs. and SLIV order to correlate the bit position in the NDI field of the DCI and the bit position in the RV field with the invalid PxSCH. The UE may then ignore NDI and RV bits/values within the NDI and RV fields associated with invalid (eg, overlapping, colliding, or conflicting) PxSCH transmissions.

Example 2 : In some cases, the position (eg, ordering) of the bits within the NDI field may be based on the order in the time domain of a valid SLIV, followed by the bits corresponding to an invalid SLIV. Similarly, the position of the bits in the RV field is based on the order in the time domain of a valid SLIV, followed by the bit corresponding to an invalid SLIV.

For illustration purposes, in one example, assume that the DCI sent by the network entity to the UE schedules 8 PDSCHs in slots 0 to 7, where each PDSCH has (S, L) = (0, 14), where S represents the start symbol, and L represents the length, and the HARQ program number is 2. Furthermore, for illustration purposes, assume that slots 2 and 5 have semi-static UL transmissions scheduled.

FIG. 5 illustrates a time slot format 500, which includes a plurality of scheduled PDSCHs in a plurality of time slots (numbered as time slots 0-7). For example, as shown, time slot format 500 includes eight scheduled PDSCHs (numbered PDSCH 0-7). As shown, UL transmissions 502A and 502B are scheduled during time slots 2 and 5, respectively. In this example, the UE may decide that the valid scheduled PDSCHs are the PDSCHs scheduled in slots 0, 1, 3, 4, 6, and 7. Additionally, the UE may also decide that the invalid scheduled PDSCHs are the PDSCHs scheduled in slots 2 and 5 because these PDSCHs overlap with UL transmissions 502A and 502B.

In the case where HARQ procedure = 2 and the PDSCH scheduled in slots 2 and 5 are invalid, the HARQ procedure ID will be PDSCH 0 = 2, PDSCH 1 = 3, PDSCH 3 = 4, PDSCH 4 = 5, PDSCH 6 =6 and PDSCH 7=7. This is because the HARQ procedure ID is not incremented for invalid PDSCH transmissions.

According to Example 1 above, the NDI field may include an NDI vector of size 8. The number of bits in the NDI field (eg, 8 bits) corresponds to the number of scheduled PDSCHs (and the number of SLIVs indicated in the DCI). Regardless of whether the PDSCH is valid or not, the ordering of bits in the NDI field corresponds to the scheduled PDSCH in the time domain. Figure 6A illustrates an example NDI field 600A having an NDI vector of size 8. Therefore, NDI field 600A includes eight NDI bits (numbered NDI 0-7). As shown in the figure, the ordering of NDI bits included in the NDI field 600A may be based on Example 1 above. Therefore, NDI 0 corresponds to PDSCH 0, NDI 1 corresponds to PDSCH 1, NDI 2 corresponds to PDSCH 2, NDI 3 corresponds to PDSCH 3, NDI 4 corresponds to PDSCH 4, NDI of the time slot format 500 shown in Figure 5 5 corresponds to PDSCH 5, and so on.

Figure 6B illustrates an example RV field 600B with an RV vector of size 8, which includes eight RV bits (numbered RV 0-7). As shown in the figure, the ordering of RV bits included in the RV field 600B may be based on Example 1 above. The number of bits in the RV (eg, 8) corresponds to the number of scheduled PDSCHs (and the number of SLIVs indicated in the DCI). Regardless of whether the PDSCH is valid or not, the ordering of the RV bits in the RV field 600B corresponds to the scheduled PDSCH in the time domain. Therefore, in FIG. 6B, RV 0 corresponds to PDSCH 0, RV 1 corresponds to PDSCH 1, RV 2 corresponds to PDSCH 2, RV 3 corresponds to PDSCH 3, and RV 4 correspond to the slot format 500 shown in FIG. 5 For PDSCH 4, RV 5 corresponds to PDSCH 5, and so on.

As mentioned above, since the previously scheduled UL transmissions 502A and 502B overlap in time with the scheduled PDSCH 2 and PDSCH 5 shown in the slot format 500 in FIG. 5, the UE can decide PDSCH 2 and PDSCH 5 is invalid. Since the ordering of bits in each of NDI field 600A and RV field 600B corresponds to the scheduled PDSCH in the time domain (eg, PDSCH 0-7 in Figure 5), the UE may discard, The NDI and RV bits corresponding to PDSCH 2 in time slot 2 of time slot format 500 and the NDI and RV bits corresponding to PDSCH 5 in time slot 5 of time slot format 500 are discarded or ignored. In this example, the UE may ignore the bits corresponding to NDI 2 and NDI 5 in the NDI field 600A and the bits corresponding to RV 2 and RV 5 in the RV field 600B because they respectively correspond to Invalid PDSCH 2 and Invalid PDSCH 5 scheduled in time slots 2 and 5. In other words, in Figures 6A and 6B, the UE can ignore NDI 2 and NDI 5 in the NDI field 600A and RV 2 and RV 5 in the RV field 600B.

Figure 7A illustrates an example NDI field 700A according to Example 2 above. According to Example 2 , NDI field 700A may still include an NDI vector of size 8. Additionally, the number of NDI bits (eg, 8) in NDI field 700A may correspond to the number of scheduled PDSCHs (and the number of SLIVs indicated in the DCI). As discussed above, in Example 2 , NDIs corresponding to valid PDSCHs are ordered first, followed by NDIs corresponding to invalid PDSCHs. Therefore, as shown in Figure 7A, the order of the NDI bits in the NDI field 700A is NDI 0, NDI 1, NDI 3, NDI 4, NDI 6, NDI 7 (each of which corresponds to the time slot format of Figure 5 500), followed by NDI 2 and NDI 5 (which correspond to the invalid PDSCH 2 and PDSCH 5 in slots 2 and 5 of slot format 500). Therefore, the UE may ignore, discard, or discard NDIs corresponding to invalid PDSCHs scheduled in slots 2 and 5. In other words, the UE may ignore NDI 2 corresponding to invalid PDSCH 2 in slot 2 and NDI 5 corresponding to invalid PDSCH 5 in slot 5, respectively.

Figure 7B illustrates an example RV field 700B according to Example 2 above. According to Example 2 , RV field 700B may still include an RV vector of size 8. Furthermore, the number of bits in RV field 700B (eg, 8) corresponds to the number of scheduled PDSCHs (and the number of SLIVs indicated in the DCI). As discussed above, in Example 2 , RVs corresponding to valid PDSCHs are ordered first, followed by RVs corresponding to invalid PDSCHs. Therefore, as shown in Figure 7B, the sequence of RV bits in RV field 700B is RV 0, RV 1, RV 3, RV 4, RV 6, RV 7 (each of which corresponds to the time slot format of Figure 5 500), followed by RV 2 and RV 5 (which correspond to the invalid PDSCH 2 and PDSCH 5 in slots 2 and 5 of slot format 500). Therefore, the UE may ignore, discard, or give up RVs corresponding to invalid PDSCHs scheduled in slots 2 and 5. In other words, the UE may ignore RV 2 corresponding to the invalid PDSCH 2 in slot 2 and RV 5 corresponding to the invalid PDSCH 5 in slot 5, respectively. Example operations for user devices

Figure 8 illustrates a method 800 for wireless communications by a UE, such as UE 104 in Figures 1 and 3.

The method 800 begins in step 810 with the following steps: the UE receives a DCI message that schedules a plurality of transmissions in a plurality of different time slots, wherein: (1) the first of the plurality of transmissions in the plurality of different time slots The first transmission set in the time slot set conflicts with the corresponding second transmission set previously scheduled in the first time slot set, (2) the DCI message at least includes a first field, and the first field includes a first plurality of values, each different value of the first plurality of values corresponds to a different transmission in the plurality of transmissions, and (3) the number of values in the first plurality of values is equal to the number of transmissions in the plurality of transmissions.

In step 820, the UE transmits a third transmission set of the plurality of transmissions that does not conflict with the second transmission set previously scheduled within the first time slot set.

In one example, the DCI message is scheduled for multiple PDSCHs or PUSCHs in multiple time slots. The first set of transmissions may be a PDSCH or PUSCH set that collides with transmissions corresponding to previously scheduled UL/DL transmissions of the second set. The DCI message includes at least a first field, for example, an NDI field including a first plurality of values. Each value of the NDI field corresponds to a different PDSCH/PUSCH scheduled by DCI. Note that the number of values in the NDI field is equal to the number of scheduled PDSCH/PUSCH transmissions. The UE receives the PDSCH scheduled by DCI or sends the PUSCH scheduled by DCI, and the PDSCH or PUSCH does not conflict with the previously scheduled UL/DL transmission.

In some cases, the DCI message includes at least a second field that includes a second plurality of values. In some cases, each different value of the second plurality of values corresponds to a different one of the plurality of transmissions. In some cases, the number of values in the second plurality of values is equal to the number of transmissions in the plurality of transmissions.

In some cases, the first field includes a new data indicator (NDI) field and the second field includes a redundant version (RV) field. In some cases, the first plurality of values includes a plurality of different NDI values, each different NDI value corresponding to a different one of the plurality of transmissions. In some cases, the second plurality of values includes a plurality of different RV values, each different RV value corresponding to a different one of the plurality of transmissions.

In some cases, the method 800 also includes determining a first different set of NDI values corresponding to a third set of transmissions from a plurality of different NDI values, the third set of transmissions being the same as the third set of NDI values previously scheduled within the first set of time slots. The two transmission sets do not conflict. In some cases, the method 800 also includes determining a second different set of NDI values from a plurality of different NDI values corresponding to the first set of transmissions, the first set of transmissions being the same as the first set of NDI values previously scheduled within the first set of time slots. Two transmission sets conflict. In some cases, the method 800 also includes determining a third different set of RV values corresponding to a third set of transmissions from a plurality of different RV values, the third set of transmissions being the same as the third set of transmissions previously scheduled within the first set of time slots. The two transmission sets do not conflict. In some cases, the method 800 also includes determining a fourth different set of RV values corresponding to a first set of transmissions from a plurality of different RV values, the first set of transmissions being the same as the first set of RV values previously scheduled within the first set of time slots. Two transmission sets conflict.

In some cases, transmitting the third transmission set in step 820 includes transmitting the third transmission set using a first different set of NDI values and a third different set of RV values. Additionally, in some cases, transmitting the third transmission set in step 820 includes discarding a second different set of NDI values and a fourth different set of RV values corresponding to the first transmission set that was different from the first set of transmissions previously provided in the first transmission set. A second transmission set scheduled within the slot set conflicts. In this way, the UE uses valid NDI and RV values.

In some cases, determining the first set of different NDI values and the second set of different NDI values depends on the bit position of the different NDI values among the plurality of different NDI values in the NDI field. In some cases, the bit positions of different NDI values in the NDI field are based on a first transmission set of the plurality of transmissions that conflicts with a corresponding second transmission set.

In some cases, according to Example 2 above, a bit position of a different NDI value in the NDI field corresponding to a first set of transmissions in the plurality of transmissions appears in the NDI field with a third transmission in the plurality of transmissions. After collecting the bit positions corresponding to different NDI values. In some cases, the first different set of NDI values includes different NDI values in bit positions in the NDI field that correspond to a third set of the plurality of transmissions. Additionally, in some cases, the second different set of NDI values includes different NDI values in bit positions in the NDI field that correspond to the first set of the plurality of transmissions.

In some cases, according to Example 1 above, the bit positions of different NDI values in the NDI field corresponding to the first transmission set of the plurality of transmissions and the third transmission set of the plurality of transmissions are according to the plurality of transmissions. Values appear sequentially. In some cases, the first different set of NDI values includes different NDI values in bit positions in the NDI field that correspond to a third set of the plurality of transmissions. Additionally, in some cases, the second different set of NDI values includes different NDI values in bit positions in the NDI field that correspond to the first set of the plurality of transmissions.

A similar procedure applies to RV fields. Therefore, in some cases, determining the third set of different RV values and the fourth set of different RV values depends on the bit positions of different RV values among the plurality of different RV values within the RV field. In some cases, the bit positions of different RV values within the RV field are based on a first transmission set of the plurality of transmissions that collides with a corresponding second transmission set.

In some cases, according to Example 2 above, a bit position with a different RV value in the RV field corresponding to a first set of transfers in the plurality of transfers appears in the RV field with a third transfer in the plurality of transfers. After collecting the bit positions corresponding to different RV values. In some cases, the third different set of RV values includes different RV values within bit positions in the RV field corresponding to a third set of the plurality of transmissions. Additionally, in some cases, the fourth different set of RV values includes different RV values within the bit positions in the RV field corresponding to the first set of the plurality of transmissions.

In some cases, according to Example 1 above, the bit positions of different RV values in the RV field corresponding to the first transmission set of the plurality of transmissions and the third transmission set of the plurality of transmissions are according to the plurality of transmissions. Values appear sequentially. In some cases, the third different set of RV values includes different RV values within bit positions in the RV field corresponding to a third set of the plurality of transmissions. Additionally, in some cases, the fourth different set of RV values includes different RV values within the bit positions in the RV field corresponding to the first set of the plurality of transmissions.

In one aspect, method 800, or any aspect related thereto, may be performed by a device, such as communications device 1000 of FIG. 10, including various components operable, configured, or adapted to perform method 800. Communications device 1000 is described in further detail below.

Note that Figure 8 is only one example of a method, and other methods including fewer, additional or alternative steps are possible consistent with the present invention. Example operations for network entities

Figure 9 illustrates a method 900 for wireless communications by a network entity, such as the BS 102 in Figures 1 and 3, or the disaggregated base station discussed with reference to Figure 2. Method 900 includes steps corresponding to method 800.

Method 900 begins in step 910 with the following operations: the network entity sends a DCI message that schedules a plurality of transmissions in a plurality of different time slots, wherein: (1) the first of the plurality of transmissions in a plurality of different time slots The first transmission set in a time slot set conflicts with the corresponding second transmission set previously scheduled in the first time slot set, (2) the DCI message at least includes a first field, and the first field includes a first a plurality of values, each different value of the first plurality of values corresponding to a different transmission of the plurality of transmissions, and (3) the number of values in the first plurality of values is equal to a transmission of the plurality of transmissions quantity.

In step 920, the network entity transmits a third transmission set of the plurality of transmissions that does not conflict with the second transmission set previously scheduled within the first time slot set.

In one example, the DCI message is scheduled for multiple PDSCHs or PUSCHs in multiple time slots. The first set of transmissions may be a set of PDSCH or PUSCH that collides with transmissions corresponding to the second set of previously scheduled UL/DL transmissions. The DCI message includes at least a first field, for example, an NDI field including a first plurality of values. Each value of the NDI field corresponds to a different PDSCH/PUSCH scheduled by DCI. Note that the number of values in the NDI field is equal to the number of scheduled PDSCH/PUSCH transmissions. The UE receives the PDSCH scheduled by DCI or sends the PUSCH scheduled by DCI, and the PDSCH or PUSCH does not conflict with the previously scheduled UL/DL transmission.

In some cases, the DCI message includes at least a second field that includes a second plurality of values. In some cases, each different value of the second plurality of values corresponds to a different one of the plurality of transmissions. In some cases, the number of values in the second plurality of values is equal to the number of transmissions in the plurality of transmissions.

In some cases, the first field includes a new data indicator (NDI) field and the second field includes a redundant version (RV) field. In some cases, the first plurality of values includes a plurality of different NDI values, each different NDI value corresponding to a different one of the plurality of transmissions. In some cases, the second plurality of values includes a plurality of different RV values, each different RV value corresponding to a different one of the plurality of transmissions.

In some cases, the method 900 also includes: determining a first different set of NDI values from the plurality of different NDI values corresponding to a third set of transmissions, the third set of transmissions being the same as the first set of NDI values previously scheduled within the first set of time slots. The two transmission sets do not conflict. In some cases, the method 900 also includes determining a second different set of NDI values from a plurality of different NDI values corresponding to the first set of transmissions, the first set of transmissions being the same as the first set of NDI values previously scheduled within the first set of time slots. Two transmission sets conflict. In some cases, the method 900 also includes determining a third different set of RV values corresponding to a third set of transmissions from a plurality of different RV values, the third set of transmissions being the same as a third set of previously scheduled time slots in the first set of time slots. The two transmission sets do not conflict. In some cases, the method 900 also includes determining a fourth different set of RV values from the plurality of different RV values corresponding to a first set of transmissions that are previously scheduled within the first set of time slots. Second transmission set conflict.

In some cases, determining the first set of different NDI values and the second set of different NDI values depends on the bit position of the different NDI values among the plurality of different NDI values in the NDI field. In some cases, the bit positions of different NDI values in the NDI field are based on a first transmission set of the plurality of transmissions that conflicts with a corresponding second transmission set.

In some cases, according to Example 2 above, a bit position of a different NDI value in the NDI field corresponding to a first set of transmissions in the plurality of transmissions appears in the NDI field with a third transmission in the plurality of transmissions. After collecting the bit positions corresponding to different NDI values. In some cases, the first different set of NDI values includes different NDI values in bit positions in the NDI field that correspond to a third set of the plurality of transmissions. Additionally, in some cases, the second different set of NDI values includes different NDI values in bit positions in the NDI field that correspond to the first set of the plurality of transmissions.

In some cases, according to Example 1 above, the bit positions of different NDI values in the NDI field corresponding to the first transmission set of the plurality of transmissions and the third transmission set of the plurality of transmissions are according to the plurality of transmissions. Values appear sequentially. In some cases, the first different set of NDI values includes different NDI values in bit positions in the NDI field that correspond to a third set of the plurality of transmissions. Additionally, in some cases, the second different set of NDI values includes different NDI values in bit positions in the NDI field that correspond to the first set of the plurality of transmissions.

A similar procedure applies to RV fields. Therefore, in some cases, determining the third set of different RV values and the fourth set of different RV values depends on the bit positions of the different RV values among the plurality of different RV values within the RV field. In some cases, the bit positions of different RV values within the RV field are based on a first transmission set of the plurality of transmissions that conflicts with a corresponding second transmission set.

In some cases, according to Example 2 above, a bit position with a different RV value in the RV field corresponding to a first set of transfers in the plurality of transfers appears in the RV field with a third transfer in the plurality of transfers. After collecting the bit positions corresponding to different RV values. In some cases, the third different set of RV values includes different RV values within bit positions in the RV field corresponding to a third set of the plurality of transmissions. Additionally, in some cases, the fourth different set of RV values includes different RV values within the bit positions in the RV field corresponding to the first set of the plurality of transmissions.

In some cases, according to Example 1 above, the bit positions of different RV values in the RV field corresponding to the first transmission set of the plurality of transmissions and the third transmission set of the plurality of transmissions are according to the plurality of transmissions. Values appear sequentially. In some cases, the third different set of RV values includes different RV values within bit positions in the RV field corresponding to a third set of the plurality of transmissions. Additionally, in some cases, the fourth different set of RV values includes different RV values within the bit positions in the RV field corresponding to the first set of the plurality of transmissions.
