Description
The present disclosure relates generally to communication systems, and more particularly, to a wireless communication system with uplink transmission repetition.
Introduction
Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.
These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR) . 5G NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT) ) , and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB) , massive machine type communications (mMTC) , and ultra-reliable low latency communications (URLLC) . Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. There exists a need for further improvements in 5G NR technology. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies.

The detailed description set forth below in connection with the appended drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well known structures and components are shown in block diagram form in order to avoid obscuring such concepts.
Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as “elements” ) . These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.
By way of example, an element, or any portion of an element, or any combination of elements may be implemented as a “processing system” that includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs) , central processing units (CPUs) , application processors, digital signal processors (DSPs) , reduced instruction set computing (RISC) processors, systems on a chip (SoC) , baseband processors, field programmable gate arrays (FPGAs) , programmable logic devices (PLDs) , state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system may execute software. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.
Accordingly, in one or more example embodiments, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. Storage media may be any available media that can be accessed by a computer. By way of example, and not limitation, such computer-readable media can comprise a random-access memory (RAM) , a read-only memory (ROM) , an electrically erasable programmable ROM (EEPROM) , optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the aforementioned types of computer-readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer.
FIG. 1 is a diagram illustrating an example of a wireless communications system and an access network 100. The wireless communications system (also referred to as a wireless wide area network (WWAN) ) includes base stations 102, UEs 104, an Evolved Packet Core (EPC) 160, and another core network 190 (e.g., a 5G Core (5GC) ) . The base stations 102 may include macrocells (high power cellular base station) and/or small cells (low power cellular base station) . The macrocells include base stations. The small cells include femtocells, picocells, and microcells.
The base stations 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN) ) may interface with the EPC 160 through first backhaul links 132 (e.g., S1 interface) . The base stations 102 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN) ) may interface with core network 190 through second backhaul links 184. In addition to other functions, the base stations 102 may perform one or more of the following functions: transfer of user data, radio channel ciphering and deciphering, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity) , inter-cell interference coordination, connection setup and release, load balancing, distribution for non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS) , subscriber and equipment trace, RAN information management (RIM) , paging, positioning, and delivery of warning messages. The base stations 102 may communicate directly or indirectly (e.g., through the EPC 160 or core network 190) with each other over third backhaul links 134 (e.g., X2 interface) . The first backhaul links 132, the second backhaul links 184, and the third backhaul links 134 may be wired or wireless.
The base stations 102 may wirelessly communicate with the UEs 104. Each of the base stations 102 may provide communication coverage for a respective geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, the small cell 102' may have a coverage area 110' that overlaps the coverage area 110 of one or more macro base stations 102. A network that includes both small cell and macrocells may be known as a heterogeneous network. A heterogeneous network may also include Home Evolved Node Bs (eNBs) (HeNBs) , which may provide service to a restricted group known as a closed subscriber group (CSG) . The communication links 120 between the base stations 102 and the UEs 104 may include uplink (UL) (also referred to as reverse link) transmissions from a UE 104 to a base station 102 and/or downlink (DL) (also referred to as forward link) transmissions from a base station 102 to a UE 104. The communication links 120 may use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and/or transmit diversity. The communication links may be through one or more carriers. The base stations 102/UEs 104 may use spectrum up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) bandwidth per carrier allocated in a carrier aggregation of up to a total of Yx MHz (x component carriers) used for transmission in each direction. The carriers may or may not be adjacent to each other. Allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL than for UL) . The component carriers may include a primary component carrier and one or more secondary component carriers. A primary component carrier may be referred to as a primary cell (PCell) and a secondary component carrier may be referred to as a secondary cell (SCell) .
The wireless communications system may further include a Wi-Fi access point (AP) 150 in communication with Wi-Fi stations (STAs) 152 via communication links 154, e.g., in a 5 GHz unlicensed frequency spectrum or the like. When communicating in an unlicensed frequency spectrum, the STAs 152/AP 150 may perform a clear channel assessment (CCA) prior to communicating in order to determine whether the channel is available.
The small cell 102' may operate in a licensed and/or an unlicensed frequency spectrum. When operating in an unlicensed frequency spectrum, the small cell 102' may employ NR and use the same unlicensed frequency spectrum (e.g., 5 GHz, or the like) as used by the Wi-Fi AP 150. The small cell 102', employing NR in an unlicensed frequency spectrum, may boost coverage to and/or increase capacity of the access network.
The electromagnetic spectrum is often subdivided, based on frequency/wavelength, into various classes, bands, channels, etc. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz –7.125 GHz) and FR2 (24.25 GHz –52.6 GHz) . The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz –300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band.
With the above aspects in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like if used herein may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like if used herein may broadly represent frequencies that may include mid-band frequencies, may be within FR2, or may be within the EHF band.
A base station 102, whether a small cell 102' or a large cell (e.g., macro base station) , may include and/or be referred to as an eNB, gNodeB (gNB) , or another type of base station. Some base stations, such as gNB 180 may operate in a traditional sub 6 GHz spectrum, in millimeter wave frequencies, and/or near millimeter wave frequencies in communication with the UE 104. When the gNB 180 operates in millimeter wave or near millimeter wave frequencies, the gNB 180 may be referred to as a millimeter wave base station. The millimeter wave base station 180 may utilize beamforming 182 with the UE 104 to compensate for the path loss and short range. The base station 180 and the UE 104 may each include a plurality of antennas, such as antenna elements, antenna panels, and/or antenna arrays to facilitate the beamforming.
The base station 180 may transmit a beamformed signal to the UE 104 in one or more transmit directions 182'. The UE 104 may receive the beamformed signal from the base station 180 in one or more receive directions 182” . The UE 104 may also transmit a beamformed signal to the base station 180 in one or more transmit directions. The base station 180 may receive the beamformed signal from the UE 104 in one or more receive directions. The base station 180/UE 104 may perform beam training to determine the best receive and transmit directions for each of the base station 180/UE 104. The transmit and receive directions for the base station 180 may or may not be the same. The transmit and receive directions for the UE 104 may or may not be the same.
The EPC 160 may include a Mobility Management Entity (MME) 162, other MMEs 164, a Serving Gateway 166, a Multimedia Broadcast Multicast Service (MBMS) Gateway 168, a Broadcast Multicast Service Center (BM-SC) 170, and a Packet Data Network (PDN) Gateway 172. The MME 162 may be in communication with a Home Subscriber Server (HSS) 174. The MME 162 is the control node that processes the signaling between the UEs 104 and the EPC 160. Generally, the MME 162 provides bearer and connection management. All user Internet protocol (IP) packets are transferred through the Serving Gateway 166, which itself is connected to the PDN Gateway 172. The PDN Gateway 172 provides UE IP address allocation as well as other functions. The PDN Gateway 172 and the BM-SC 170 are connected to the IP Services 176. The IP Services 176 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS) , a PS Streaming Service, and/or other IP services. The BM-SC 170 may provide functions for MBMS user service provisioning and delivery. The BM-SC 170 may serve as an entry point for content provider MBMS transmission, may be used to authorize and initiate MBMS Bearer Services within a public land mobile network (PLMN) , and may be used to schedule MBMS transmissions. The MBMS Gateway 168 may be used to distribute MBMS traffic to the base stations 102 belonging to a Multicast Broadcast Single Frequency Network (MBSFN) area broadcasting a particular service, and may be responsible for session management (start/stop) and for collecting eMBMS related charging information.
The core network 190 may include a Access and Mobility Management Function (AMF) 192, other AMFs 193, a Session Management Function (SMF) 194, and a User Plane Function (UPF) 195. The AMF 192 may be in communication with a Unified Data Management (UDM) 196. The AMF 192 is the control node that processes the signaling between the UEs 104 and the core network 190. Generally, the AMF 192 provides QoS flow and session management. All user Internet protocol (IP) packets are transferred through the UPF 195. The UPF 195 provides UE IP address allocation as well as other functions. The UPF 195 is connected to the IP Services 197. The IP Services 197 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS) , a Packet Switch (PS) Streaming (PSS) Service, and/or other IP services.
The base station may include and/or be referred to as a gNB, Node B, eNB, an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS) , an extended service set (ESS) , a transmit reception point (TRP) , or some other suitable terminology. The base station 102 provides an access point to the EPC 160 or core network 190 for a UE 104. Examples of UEs 104 include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA) , a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player) , a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor/actuator, a display, or any other similar functioning device. Some of the UEs 104 may be referred to as IoT devices (e.g., parking meter, gas pump, toaster, vehicles, heart monitor, etc. ) . The UE 104 may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology.
Referring again to FIG. 1, the UE 104 includes an uplink transmission repetition component 199. The uplink transmission repetition component 199 may determine a location of one or more uplink data retransmissions associated with an uplink data channel, a location of at least one uplink data retransmission of the one or more uplink data retransmissions corresponding to a cross slot boundary such that a first portion of the at least one uplink data retransmission corresponds to a first slot and a second portion of the at least one uplink data retransmission corresponds to a second slot. The uplink transmission repetition component 199 may configure the one or more uplink data retransmissions based on the determined location of the one or more uplink data retransmissions, each of the one or more uplink data retransmissions including CG-UCI. The uplink transmission repetition component 199 may transmit the one or more uplink data retransmissions including the CG-UCI via the uplink data channel.
Although the following description may be focused on 5G NR, the concepts described herein may be applicable to other similar areas, such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.
FIG. 2A is a diagram 200 illustrating an example of a first subframe within a 5G NR frame structure. FIG. 2B is a diagram 230 illustrating an example of DL channels within a 5G NR subframe. FIG. 2C is a diagram 250 illustrating an example of a second subframe within a 5G NR frame structure. FIG. 2D is a diagram 280 illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be frequency division duplexed (FDD) in which for a particular set of subcarriers (carrier system bandwidth) , subframes within the set of subcarriers are dedicated for either DL or UL, or may be time division duplexed (TDD) in which for a particular set of subcarriers (carrier system bandwidth) , subframes within the set of subcarriers are dedicated for both DL and UL. In the examples provided by FIGs. 2A, 2C, the 5G NR frame structure is assumed to be TDD, with subframe 4 being configured with slot format 28 (with mostly DL) , where D is DL, U is UL, and F is flexible for use between DL/UL, and subframe 3 being configured with slot format 1 (with all UL) . While subframes 3, 4 are shown with slot formats 1, 28, respectively, any particular subframe may be configured with any of the various available slot formats 0-61. Slot formats 0, 1 are all DL, UL, respectively. Other slot formats 2-61 include a mix of DL, UL, and flexible symbols. UEs are configured with the slot format (dynamically through DL control information (DCI) , or semi-statically/statically through radio resource control (RRC) signaling) through a received slot format indicator (SFI) . Note that the description infra applies also to a 5G NR frame structure that is TDD.
Other wireless communication technologies may have a different frame structure and/or different channels. A frame (10 ms) may be divided into 10 equally sized subframes (1 ms) . Each subframe may include one or more time slots. Subframes may also include mini-slots, which may include 7, 4, or 2 symbols. Each slot may include 7 or 14 symbols, depending on the slot configuration. For slot configuration 0, each slot may include 14 symbols, and for slot configuration 1, each slot may include 7 symbols. The symbols on DL may be cyclic prefix (CP) OFDM (CP-OFDM) symbols. The symbols on UL may be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbols (also referred to as single carrier frequency-division multiple access (SC-FDMA) symbols) (for power limited scenarios; limited to a single stream transmission) . The number of slots within a subframe is based on the slot configuration and the numerology. For slot configuration 0, different numerologies μ0 to 4 allow for 1, 2, 4, 8, and 16 slots, respectively, per subframe. For slot configuration 1, different numerologies 0 to 2 allow for 2, 4, and 8 slots, respectively, per subframe. Accordingly, for slot configuration 0 and numerology μ, there are 14 symbols/slot and 2
μ slots/subframe. The subcarrier spacing and symbol length/duration are a function of the numerology. The subcarrier spacing may be equal to 2
μ*15 kHz, where μ is the numerology 0 to 4. As such, the numerology μ=0 has a subcarrier spacing of 15 kHz and the numerology μ=4 has a subcarrier spacing of 240 kHz. The symbol length/duration is inversely related to the subcarrier spacing. FIGs. 2A-2D provide an example of slot configuration 0 with 14 symbols per slot and numerology 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. Within a set of frames, there may be one or more different bandwidth parts (BWPs) (see FIG. 2B) that are frequency division multiplexed. Each BWP may have a particular numerology.
A resource grid may be used to represent the frame structure. Each time slot includes a resource block (RB) (also referred to as physical RBs (PRBs) ) that extends 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 illustrated in FIG. 2A, some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include demodulation RS (DM-RS) (indicated as R for one particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. The RS may also include beam measurement RS (BRS) , beam refinement RS (BRRS) , and phase tracking RS (PT-RS) .
FIG. 2B illustrates an example of various DL channels within a subframe of a frame. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs) , each CCE including six RE groups (REGs) , each REG including 12 consecutive REs in an OFDM symbol of an RB. A PDCCH within one BWP may be referred to as a control resource set (CORESET) . A UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., common search space, UE-specific search space) during PDCCH monitoring occasions on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at greater and/or lower frequencies across the channel bandwidth. A primary synchronization signal (PSS) may be within symbol 2 of particular subframes of a frame. The PSS is used by a UE 104 to determine subframe/symbol timing and a physical layer identity. A secondary synchronization signal (SSS) may be within symbol 4 of particular subframes of a frame. The SSS is used by a UE to determine a physical layer cell identity group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI) . Based on the PCI, the UE can determine the locations of the aforementioned DM-RS. The physical broadcast channel (PBCH) , which carries a master information block (MIB) , may be logically grouped with the PSS and SSS to form a synchronization signal (SS) /PBCH block (also referred to as SS block (SSB) ) . The MIB provides a number of RBs in the system bandwidth and a system frame number (SFN) . The physical downlink shared channel (PDSCH) carries user data, broadcast system information not transmitted through the PBCH such as system information blocks (SIBs) , and paging messages.
As illustrated in FIG. 2C, some of the REs carry DM-RS (indicated as R for one particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may transmit DM-RS for the physical uplink control channel (PUCCH) and DM-RS for the physical uplink shared channel (PUSCH) . The PUSCH DM-RS may be transmitted in the first one or two symbols of the PUSCH. The PUCCH DM-RS may be transmitted in different configurations depending on whether short or long PUCCHs are transmitted and depending on the particular PUCCH format used. The UE may transmit sounding reference signals (SRS) . The SRS may be transmitted in the last symbol of a subframe. The SRS may have a comb structure, and a UE may transmit SRS on one of the combs. The SRS may be used by a base station for channel quality estimation to enable frequency-dependent scheduling on the UL.
FIG. 2D illustrates an example of various UL channels within a subframe of a frame. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI) , such as scheduling requests, a channel quality indicator (CQI) , a precoding matrix indicator (PMI) , a rank indicator (RI) , and hybrid automatic repeat request (HARQ) ACK/NACK feedback. The PUSCH carries data, and may additionally be used to carry a buffer status report (BSR) , a power headroom report (PHR) , and/or UCI.
FIG. 3 is a block diagram of a base station 310 in communication with a UE 350 in an access network. In the DL, IP packets from the EPC 160 may be provided to a controller/processor 375. The controller/processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller/processor 375 provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIBs) , RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release) , inter radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression/decompression, security (ciphering, deciphering, integrity protection, integrity verification) , and handover support functions; RLC layer functionality associated with the transfer of upper layer packet data units (PDUs) , error correction through ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs) , re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs) , demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.
The transmit (TX) processor 316 and the receive (RX) processor 370 implement layer 1 functionality associated with various signal processing functions. Layer 1, which includes a physical (PHY) layer, may include error detection on the transport channels, forward error correction (FEC) coding/decoding of the transport channels, interleaving, rate matching, mapping onto physical channels, modulation/demodulation of physical channels, and MIMO antenna processing. The TX processor 316 handles mapping to signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK) , quadrature phase-shift keying (QPSK) , M-phase-shift keying (M-PSK) , M-quadrature amplitude modulation (M-QAM) ) . The coded and modulated symbols may then be split into parallel streams. Each stream may then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., pilot) in the time and/or frequency domain, and then combined together using an Inverse Fast Fourier Transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially precoded to produce multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation scheme, as well as for spatial processing. The channel estimate may be derived from a reference signal and/or channel condition feedback transmitted by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318 TX. Each transmitter 318 TX may modulate an RF carrier with a respective spatial stream for transmission.
At the UE 350, each receiver 354 RX receives a signal through its respective antenna 352. Each receiver 354 RX recovers information modulated onto an RF carrier and provides the information to the receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement layer 1 functionality associated with various signal processing functions. The RX processor 356 may perform spatial processing on the information to recover any spatial streams destined for the UE 350. If multiple spatial streams are destined for the UE 350, they may be combined by the RX processor 356 into a single OFDM symbol stream. The RX processor 356 then converts the OFDM symbol stream from the time-domain to the frequency domain using a Fast Fourier Transform (FFT) . The frequency domain signal comprises a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, and the reference signal, are recovered and demodulated by determining the most likely signal constellation points transmitted by the base station 310. These soft decisions may be based on channel estimates computed by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the base station 310 on the physical channel. The data and control signals are then provided to the controller/processor 359, which implements layer 3 and layer 2 functionality.
The controller/processor 359 can be associated with a memory 360 that stores program codes and data. The memory 360 may be referred to as a computer-readable medium. In the UL, the controller/processor 359 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IP packets from the EPC 160. The controller/processor 359 is also responsible for error detection using an ACK and/or NACK protocol to support HARQ operations.
Similar to the functionality described in connection with the DL transmission by the base station 310, the controller/processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIBs) acquisition, RRC connections, and measurement reporting; PDCP layer functionality associated with header compression/decompression, and security (ciphering, deciphering, integrity protection, integrity verification) ; RLC layer functionality associated with the transfer of upper layer PDUs, error correction through ARQ, concatenation, segmentation, and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.
Channel estimates derived by a channel estimator 358 from a reference signal or feedback transmitted by the base station 310 may be used by the TX processor 368 to select the appropriate coding and modulation schemes, and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antenna 352 via separate transmitters 354TX. Each transmitter 354TX may modulate an RF carrier with a respective spatial stream for transmission.
The UL transmission is processed at the base station 310 in a manner similar to that described in connection with the receiver function at the UE 350. Each receiver 318RX receives a signal through its respective antenna 320. Each receiver 318RX recovers information modulated onto an RF carrier and provides the information to a RX processor 370.
The controller/processor 375 can be associated with a memory 376 that stores program codes and data. The memory 376 may be referred to as a computer-readable medium. In the UL, the controller/processor 375 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover IP packets from the UE 350. IP packets from the controller/processor 375 may be provided to the EPC 160. The controller/processor 375 is also responsible for error detection using an ACK and/or NACK protocol to support HARQ operations.
At least one of the TX processor 368, the RX processor 356, and the controller/processor 359 may be configured to perform aspects in connection with uplink transmission repetition component 199 of FIG. 1.
To enhance connection between a base station and a UE, PUSCH repetition, such as Type B repetition, may be utilized. In some wireless communication systems utilizing PUSCH transmission Type A, one PUSCH transmission instance may not be allowed to cross the slot boundary for both dynamic grant (DG) and CG PUSCH. To avoid transmitting a long PUSCH across a slot boundary, the UE can transmit small PUSCHs in several repetitions scheduled by an UL grant or RRC in consecutive available slots. PUSCH repetition Type A may cause a large time gap among the repetitions and may make the system unable to achieve a certain URLLC latency. PUSCH transmission Type B may reduce the time gap among repetitions and may ensure the configured number of repetitions in the time constraint because the repetitions are carried out in the consecutive mini-slots, so one slot may contain more than one repetition. For PUSCH repetition Type B, a time domain resource assignment (TDRA) field in DCI or the TDRA parameters may indicate the resource for a first “nominal” repetition. The time domain resources for the remaining repetitions may be derived based at least on the resources for the first repetition and an UL/DL direction of symbols. The number of the repetitions may represent the number K of nominal repetitions (i.e., data retransmissions) .
Each nominal repetition may be of nominal length L and may be sent back-to back starting from symbol S, where S and L are given by a start and length indicator (SLIV) . Because a nominal repetition may go across a slot boundary or a downlink/uplink switching point, each nominal repetition may include one or more actual repetitions. The UE may determine invalid symbol (s) based on predefined rules or a RRC configuration. After determining the invalid symbol (s) for a PUSCH repetition Type B transmission for each of the K nominal repetitions, the remaining symbols may be considered as potentially valid symbols for the PUSCH repetition Type B transmission. If the number of potentially valid symbols for the PUSCH repetition Type B transmission is greater than zero for a nominal repetition, the nominal repetition may include one or more actual repetitions. Each actual repetition may include a consecutive set of each potentially valid symbol that may be used for a PUSCH repetition Type B transmission within a slot. An actual repetition with a single symbol may be omitted, in some instances, with an exception for the case of L=1.
FIGs. 4A and 4B illustrate example actual repetitions and nominal repetitions. As illustrated in example 400 in FIG. 4A, one nominal repetition may be split into one or more actual repetitions due to a cross slot boundary. As illustrated in example 460 in FIG. 4B, one nominal repetition may be split into one or more actual repetitions because of a conflict with semi-static DL symbols or invalid symbols.
In some aspects, CG-UCI may include a hybrid automatic repeat request (HARQ) ID, a new data indicator (NDI) , a redundancy version (RV) , and channel occupancy time (COT) sharing information. To determine the number of REs used for CG-UCI, a mechanism of beta-offset may be used. A RRC parameter may be configured to define a beta-offset for CG-UCI. In some wireless communication systems, CG-UCI may be included in each CG-PUSCH transmission, i.e., nominal repetitions and actual repetitions.
As illustrated in example 500 in FIG. 5, CG- UCI 510A, 510B, and 510C may be included in each of the actual repetitions in all nominal repetitions. The first nominal repetition 502 in FIG. 5 may include one actual repetition which includes CG-UCI 510A. The second nominal repetition 504 may include a first actual repetition 504A and a second actual repetition 504B. The first actual repetition 504A may include CG-UCI 510B. The second actual repetition 504B may include CG-UCI 510C. The first actual repetition 504A and the second actual repetition 504B may belong to a same data cluster in the nominal repetition 504. The term “data cluster” may be used to refer to a set of continuous actual repetitions in a nominal repetition. Because the second nominal repetition 504 is split into two actual repetitions 504A and 504B, the resource allocation size may be smaller for each actual repetition for second nominal repetition 504 compared to first nominal repetition 502. Because CG-UCI is included in each actual repetition, the efficiency of the transmission may be decreased as the second nominal repetition 504 dedicates more resources for the CG-UCI. Methods, apparatuses, and computer program products may be provided to reduce CG-UCI overhead.
As illustrated in example 600 of FIG. 6, in some aspects, if a nominal repetition is split into one or more actual repetitions, CG-UCI is transmitted once for the actual repetitions in each cluster and CG-UCI is transmitted in the last actual repetition in the cluster. In some aspects, if there is no gap (e.g., due to DL or invalid symbols) between actual repetitions in a nominal repetition, such as when a nominal repetition is split into one or more actual repetitions due to cross slot boundary, CG-UCI may be transmitted in the last actual repetitions in a nominal repetition. As illustrated in FIG. 6, the first nominal repetition 602 may include one actual repetition and the CG-UCI 610A may be included in the actual repetition. The second nominal repetition 604 may be split into two actual repetitions 604A and 604B due to the slot boundary. The CG-UCI 610B may be included in the second actual repetition 604B and not the first actual repetition 604A of the nominal repetition 604.
In some aspects, if there are gap (s) between actual repetitions in a nominal repetition, for example when a nominal repetition is split into one or more actual repetitions due to semi-static DL or invalid symbols, CG-UCI may be transmitted in the last actual repetitions in a cluster. As illustrated in example 700 of FIG. 7, a nominal repetition may be split into two data clusters 702 and 704 due to DL or invalid symbols. The first data cluster 702 may include two actual repetitions 702A and 702B. The CG-UCI 710A may be included in the last actual repetition 702B, but may not be in the first repetition 702A. The second cluster 704 may include one actual repetition and the CG-UCI 710B may be included in the actual repetition.
As illustrated in example 800 of FIG. 8, two nominal repetitions 802 and 804 are illustrated. The first nominal repetition 802 may include one actual repetition and the CG-UCI 810A may be included in the actual repetition. The second nominal repetition 804 may include two data clusters with each cluster including an actual repetition (804A and 804B) . Because CG-UCI is included in the last actual repetition in each data cluster, the actual repetition 804A in the first data cluster may include the CG-UCI 810B and the actual repetition 804B in the second data cluster may include the CG-UCI 810C.
In some aspects, different fields for CG-UCI can be configured on/off separately. Therefore, depending on the content of CG-UCI, different behaviors may be defined. In some aspects, if a CG retransmission timer is not configured, CG-UCI may be transmitted in each actual repetition. In such aspects, CG-UCI may be used for transmitting the COT sharing information. The CG-UCI may include fewer bits compared with other aspects to reduce the overhead. If a CG retransmission timer is configured, CG-UCI may be transmitted in the last actual repetition in each cluster.
In some aspects, instead of transmitting CG-UCI in some actual repetitions and not transmitting CG-UCI in some other actual repetitions, a different number of REs may be used for CG-UCI in different actual repetitions. In some aspects, multiple beta-offset values may be configured via RRC signaling. Each beta-offset may be mapped to one actual repetition in a nominal repetition.
In some aspects, the mapping may be based on resource size. For example, the largest beta-offset value may be used for the actual repetition with a largest resource size, the second largest beta-offset value may be used for the actual repetition with a second largest resource size, and the like. Smaller beta-offset values for smaller resource sizes may be used to reduce overhead. In another example, the largest beta-offset value may be used for the actual repetition with a smallest resource size, the second largest beta-offset value may be used for the actual repetition with a second smallest resource size, and the like. Larger beta-offset values for smaller resource sizes may be used for reserving more resources for CG-UCI for lower coding rates to ensure reliability. In yet another example, the mapping may be defined by a base station. The first beta-offset value may be used for the first actual repetition in a nominal repetition, the second beta-offset may be used for the second actual repetition in a nominal repetition, and the like for the remaining beta-offset values. In another example, an increasing order of the beta-offset values may be used. For example, the largest beta-offset value may be used for the first actual repetition in a nominal repetition, the second largest beta-offset value may be used for the second actual repetition in a nominal repetition, and the like. In another example, a decreasing order of the beta-offset values may be used. For example, the smallest beta-offset value may be used for the first actual repetition in a nominal repetition, the second smallest beta-offset value may be used for the second actual repetition in a nominal repetition, and the like.
As illustrated in example 900 of FIG. 9, each actual repetition in the nominal repetition may include a CG-UCI 910A, CG-UCI 910B, or CG-UCI 910C. Each of the CG-UCI 910A, CG-UCI 910B, or CG-UCI 910C in the actual repetitions may be associated with a different beta-offset value.
In some aspects, multiple beta-offset values can be configured via RRC signaling and each beta-offset may be used for one nominal repetition with a given number of actual repetitions. For actual repetitions in a nominal repetition, the same beta-offset may be used for each actual repetition. For example, the largest beta-offset value may be used for a nominal repetition with one actual repetition, the second largest beta-offset value may be used for a nominal repetition with two actual repetitions, and the like. Smaller beta-offset values for smaller resource sizes may be used to reduce overhead. In another example, a smallest beta-offset value may be used for a nominal repetition with one actual repetition, the second smallest beta-offset value may be used for nominal repetition with two actual repetitions, and the like. Larger beta-offset values for smaller resource sizes may be used for reserving more resources for CG-UCI for lower coding rates to ensure reliability. In yet another example, the mapping may be defined by a base station. The first beta-offset value may be used for a nominal repetition with one actual repetition, the second beta-offset value may be used for the nominal repetition with two actual repetitions, and the like for the remaining beta-offset values. Table 1 below illustrates such a configuration:
Table 1
As illustrated in example 1000 of FIG. 10, the beta-offset #0 may be used for CG-UCI 1010A in a first nominal repetition with one actual repetition and the beta-offset #1 may be used for CG-UCI 1010B and CG-UCI 1010C in a second nominal repetition with two actual repetitions.
In some aspects, multiple groups of beta-offset values can be configured via RRC signaling and each group may include a different number of beta-offset values. For example, the UE may select one group of beta-offset values based on the number of actual repetitions in a nominal repetition. Within each group, the mapping of beta- offset values and actual repetitions can be determined similar to the multiple beta-offset value configurations in previously explained aspects.
As illustrated in example 1100 of FIG. 11, a first nominal repetition 1102 may include one actual repetition which includes the CG-UCI 1110A with a first beta-offset value # 00 of group # 0. A second nominal repetition 1104 may include two actual repetitions 1104A, which include the CG-UCI 1110B with a first beta-offset value # 10 of group # 1, and 1104B, which includes the CG-UCI 1110C with a second beta-offset value # 11 of group # 1. Table 2 below illustrates such a configuration:
Group no. | Beta-offset |
0 | beta-offset #0 |
1 | beta-offset #10, beta-offset #11 |
… | … |
Table 2
FIG. 12 is a flowchart 1200 of a method of wireless communication. The method may be performed by a UE (e.g., the UE 104; the apparatus 1302, or the like) . One or more of the illustrated operations may be omitted, transposed, or contemporaneous. Optional aspects are illustrated with a dashed line.
At 1202, the UE is configured to determine a location of one or more uplink data retransmissions associated with an uplink data channel. A location of at least one uplink data retransmission of the one or more uplink data retransmissions may correspond to a cross slot boundary such that a first portion of the at least one uplink data retransmission corresponds to a first slot and a second portion of the at least one uplink data retransmission may correspond to a second slot. In some aspects, the one or more uplink data retransmission may be nominal repetitions. In some aspects, the first portion is an actual repetition of a nominal repetition and the second portion is another actual repetition of the nominal repetition. For example, the determination may be performed by location determination component 1342. In some aspects, the CG-UCI may be piggybacked on each of the one or more uplink data retransmissions. In some aspects, the at least one uplink data retransmission may be adjacent to at least one other uplink data retransmission of the one or more uplink data retransmissions. A location of the at least one other uplink data retransmission may correspond to the first slot. The at least one other uplink data retransmission may include the CG-UCI and the second portion of the at least one uplink data retransmission may include the CG-UCI.
In some aspects, a location of one or more symbols unavailable for uplink transmission may overlap with the location of the at least one uplink data retransmission. The at least one uplink data retransmission may include a first data cluster and a second data cluster. The one or more symbols unavailable for uplink transmission may be between the first data cluster and the second data cluster.
