Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. Provisional Patent Application Serial No. 63 / 022,390, filed on May 8, 2020, entitled “METHODS AND APPARATUS FOR SELECTING TRANSMISSION OF UNSENT DATA RETRANSMISSIONS,” and U.S. Patent Application No. 17 / 243,459, filed on April 28, 2021, entitled “METHODS AND APPARATUS FOR SELECTING TRANSMISSION OF UNSENT DATA RETRANSMISSIONS,” the entire contents of which are expressly incorporated herein by reference. Technical Field

[0003] The present disclosure relates generally to communication systems and, more particularly, to transmission of unsent data in wireless communication systems. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. 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.

[0005] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of the continued evolution of mobile broadband promulgated by the 3rd Generation Partnership Project (3GPP) to meet new requirements related to latency, reliability, security, scalability (e.g., 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). Certain aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. 5G NR technology requires further improvements. These improvements may also be applicable to other multiple access technologies and telecommunication standards that adopt these technologies. Summary of the invention

[0022] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configuration in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the various concepts. However, it is apparent to those skilled in the art that these concepts may be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid obfuscation of these concepts.

[0023] 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 these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0024] For example, an element or any part of an element or any combination of elements may be implemented as a "processing system" including 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 chip (SoCs), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gating logic, discrete hardware circuits, and other suitable hardware that are configured to perform various functions described throughout the present disclosure. One or more processors in a processing system may execute software. Software should be broadly interpreted as referring to instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, processes, functions, etc., whether referring to software, firmware, middleware, microcode, hardware description languages, or other.

[0025] Therefore, 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 or encoded as one or more instructions or codes on a computer-readable medium. Computer-readable media include computer storage media. Storage media may be any available media that a computer can access. As an example and not limitation, such computer-readable media may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, a combination of computer-readable media of the above types, or any other medium that can be used to store computer executable code in the form of computer-accessible instructions or data structures.

[0026] Figure 1 1 is a diagram showing an example of a wireless communication system and access network 100. The wireless communication system (also referred to as a wireless wide area network (WWAN)) includes a base station 102, a UE 104, an evolved packet core (EPC) 160, and another core network 190 (e.g., a 5G core (5GC)). The base station 102 may include a macro cell (a high-power cellular base station) and / or a small cell (a low-power cellular base station). A macro cell includes a base station. A small cell includes a femto cell, a pico cell, and a micro cell.

[0027] A base station 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 via a first backhaul link 132 (e.g., an S1 interface). A base station 102 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) may interface with the core network 190 via a second backhaul link 184. The base station 102 may perform, among other functions, one or more of the following functions: transmission of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, non-access stratum (NAS) message distribution, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), user and device tracking, RAN information management (RIM), paging, positioning, and delivery of warning messages. The base stations 102 may communicate with each other directly or indirectly (eg, through the EPC 160 or the core network 190) via a third backhaul link 134 (eg, an X2 interface). The third backhaul link 134 may be wired or wireless.

[0028] Base station 102 can communicate wirelessly with UE 104. Each base station 102 can provide communication coverage for a corresponding geographic coverage area 110. There can be overlapping geographic coverage areas 110. For example, a small cell 102' can have a coverage area 110' that overlaps with the coverage area 110 of one or more macro base stations 102. A network including small cells and macro cells can be referred to as a heterogeneous network. A heterogeneous network can also include a home evolved Node B (eNB) (HeNB), which can provide services to a restricted group called a closed subscriber group (CSG). The communication link 120 between base station 102 and UE 104 can include an uplink (UL) (also called a reverse link) transmission from UE 104 to base station 102 and / or a downlink (DL) (also called a forward link) transmission from base station 102 to UE 104. The communication link 120 can use multiple input multiple output (MIMO) antenna technology, including spatial multiplexing, beamforming and / or transmit diversity. The communication link can be through one or more carriers. The base station 102 / UE 104 may use spectrum of up to Y MHz (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.) bandwidth per carrier allocated in carrier aggregation (x component carriers) totaling up to Yx MHz for transmission in each direction. The carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric for 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. The primary component carrier may be referred to as a primary cell (PCell) and the secondary component carrier may be referred to as a secondary cell (SCell).

[0029] Certain UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use DL / UL WWAN spectrum. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSSCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). The D2D communication may be through various wireless D2D communication systems, such as FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.

[0030] The wireless communication system also includes a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 in the 5 GHz unlicensed spectrum via a communication link 154. When communicating in the unlicensed spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) to determine whether the channel is available prior to communication.

[0031] The small cell 102' may operate in a licensed and / or unlicensed spectrum. When operating in an unlicensed spectrum, the small cell 102' may employ NR and use the same 5 GHz unlicensed spectrum used by the Wi-Fi AP 150. The small cell 102' employing NR in the unlicensed spectrum may expand the coverage of the access network and / or increase the capacity of the access network.

[0032] Base station 102, whether a small cell 102' or a large cell (e.g., a macro base station), can include and / or be referred to as an eNB, gNodeB (gNB), or other type of base station. Some base stations, such as gNB 180, can operate in traditional sub-6 GHz spectrum, millimeter wave (mmW) frequencies, and / or near mmW frequencies for communicating with UE 104. When gNB 180 operates in mmW or near mmW frequencies, gNB 180 can be referred to as a mmW base station. Extremely high frequency (EHF) is a portion of RF in the electromagnetic spectrum. EHF ranges from 30 GHz to 300 GHz and has a wavelength between 1 mm and 10 mm. Radio waves in this band can be referred to as millimeter waves. Near millimeter waves may extend down to frequencies of 3 GHz, with a wavelength of 100 mm. The super high frequency (SHF) band extends between 3 GHz and 30 GHz and is also called centimeter waves. Communications using millimeter wave / near millimeter wave radio frequency bands (e.g., 3 GHz–300 GHz) have extremely high path losses and short distances. The mmW base station 180 may utilize beamforming 182 for the UE 104 to compensate for the extremely high path loss and short range. The base station 180 and the UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays to facilitate beamforming.

[0033] The base station 180 may transmit beamformed signals in one or more transmit directions 182' to the UE 104. The UE 104 may receive beamformed signals from the base station 180 in one or more receive directions 182". The UE 104 may also transmit beamformed signals to the base station 180 in one or more transmit directions. The base station 180 may receive beamformed signals 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 base station 180 / UE 104. The transmit and receive directions of the base station 180 may be the same or different. The transmit and receive directions of the UE 104 may be the same or different.

[0034] The EPC 160 may include a mobile 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 communicate with a home subscriber server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. Typically, the MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are transmitted through the serving gateway 166, which itself is connected to the PDN gateway 172. The PDN gateway 172 provides UE IP address allocation and other functions. The PDN gateway 172 and the BM-SC 170 are connected to IP services 176. The IP services 176 may include the Internet, an intranet, an IP multimedia subsystem (IMS), a packet switched (PS) streaming service, and / or other intellectual property services. The BM-SC 170 may provide functionality for MBMS user service provisioning and delivery. The BM-SC 170 may serve 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 may be used to schedule MBMS transmissions. The MBMS Gateway 168 may be used to distribute MBMS traffic to base stations 102 belonging to a multicast broadcast single frequency network (MBSFN) area that broadcasts specific services, and may be responsible for session management (start / stop) and collecting charging information related to eMBMS.

[0035] The core network 190 may include an 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 communicate with a unified data management (UDM) 196. The AMF 192 is a control node that handles signaling between the UE 104 and the core network 190. Typically, the AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are transmitted through the UPF 195. The UPF 195 provides UE IP address allocation and other functions. The UPF 195 is connected to an IP service 197. The IP service 197 may include the Internet, an intranet, an IP multimedia subsystem (IMS), a PS streaming service, and / or other IP services.

[0036] Base stations may include and / or be referred to as gNBs, Node Bs, eNBs, access points, base transceivers, radio base stations, radio transceivers, transceiver functions, basic service sets (BSSs), extended service sets (ESSs), transmit receive points (TRPs), or some other suitable terminology. Base stations 102 provide access points to EPC 160 or core network 190 for UEs 104. Examples of UEs 104 include cellular phones, smart phones, session initiation protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablets, smart devices, wearable devices, vehicles, electric meters, gas pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other similarly functional device. Some of UEs 104 may be referred to as IoT devices (e.g., parking meters, gas pumps, toasters, vehicles, heart monitors, etc.). 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 communication 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.

[0037] Reference again Figure 1 In certain aspects, the UE 104 may include a receiving component 198 configured to receive a selection process for uplink transmission from a base station, wherein the selection process may include information for uplink data retransmissions. The receiving component 198 may also be configured to implement the selection process for uplink transmissions. The receiving component 198 may also be configured to determine that data cannot be retransmitted via the PUSCH, wherein the data determined to be unable to be retransmitted via the PUSCH may correspond to unsent PUSCH data retransmissions. The receiving component 198 may also be configured to send at least one uplink transmission to the base station based on the selection process for uplink transmissions. The receiving component 198 may also be configured to send the data determined to be unable to be retransmitted via the PUSCH via a configured grant.

[0038] Reference again Figure 1In certain aspects, the receiving component 198 may be configured to determine a selection process for an uplink transmission, the selection process including information for uplink data retransmissions, wherein the information for uplink data retransmissions may correspond to specification information. The receiving component 198 may also be configured to identify whether the transmission of the unsent PUSCH data retransmission is via a configured grant. The receiving component 198 may also be configured to select the configured grant for the transmission of the unsent PUSCH data retransmission. The receiving component 198 may also be configured to implement the selection process for the uplink transmission. The receiving component 198 may also be configured to determine that data cannot be retransmitted via the PUSCH, wherein the data determined to be unsent via the PUSCH retransmission may correspond to the unsent PUSCH data retransmission. The receiving component 198 may also be configured to send at least one uplink transmission to the base station based on the selection process for the uplink transmission. The receiving component 198 may also be configured to send the data determined to be unsent via the PUSCH retransmission via the configured grant.

[0039] Reference again Figure 1 In certain aspects, the base station 180 may include a transmission component 199 configured to determine a selection process for an uplink transmission, wherein the selection process may include information for uplink data retransmissions. The transmission component 199 may also be configured to identify whether the transmission of an unsent PUSCH data retransmission is via a configured grant. The transmission component 199 may also be configured to select a configured grant for the transmission of an unsent PUSCH data retransmission. The transmission component 199 may also be configured to send the selection process for the uplink transmission to a user equipment (UE). The transmission component 199 may also be configured to monitor at least one uplink transmission from the UE based on the selection process for the uplink transmission. The transmission component 199 may also be configured to receive at least one uplink transmission from the UE based on the selection process for the uplink transmission.

[0040] Although the following description may focus on 5G NR, the concepts described herein are applicable to other similar areas such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.

[0041] Figure 2A FIG200 is a diagram illustrating an example of a first subframe within a 5G / NR frame structure. Figure 2B FIG230 is a diagram illustrating an example of DL channels within a 5G / NR subframe. Figure 2C FIG250 is a diagram illustrating an example of a second subframe within a 5G / NR frame structure. Figure 2D280 is a diagram illustrating an example of a UL channel within a 5G / NR subframe. The 5G / NR frame structure can be frequency division duplex (FDD), where for a particular set of subcarriers (carrier system bandwidth), the subframes within the set of subcarriers are dedicated to DL or UL, or can be time division duplex (TDD), where for a particular set of subcarriers (carrier system bandwidth), the subframes within the set of subcarriers are dedicated to DL and UL. In the examples provided in 2A and 2C, it is assumed that the 5G / NR frame structure is TDD, subframe 4 is configured with slot format 28 (mostly DL), where D is DL, U is UL, and X can be flexibly used between DL / UL, and subframe 3 is configured with slot format 34 (mainly UL). Although subframes 3 and 4 are shown with slot formats 34 and 28, respectively, any particular subframe can be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are DL and UL, respectively. Other slot formats 2-61 include a mix of DL, UL and flexible symbols. The UE configures the slot format via the received slot format indicator (SFI) (dynamically via DL control information (DCI), or semi-statically / statically via radio resource control (RRC) signaling). Please note that the description below also applies to the 5G / NR frame structure for TDD.

[0042] Other wireless communication technologies may have different frame structures and / or different channels. A frame (10 milliseconds) can be divided into 10 equally sized subframes (1 millisecond). Each subframe may include one or more time slots. A subframe may also include a microslot, which may include 7, 4, or 2 symbols. Each time slot may include 7 or 14 symbols, depending on the time slot configuration. For time slot configuration 0, each time slot may include 14 symbols, and for time slot configuration 1, each time slot may include 7 symbols. The symbols on the DL may be cyclic prefix (CP) OFDM (CP-OFDM) symbols. The symbols on the UL may be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbols (also known as single carrier frequency division multiple access (SC-FDMA) symbols) (for power-limited scenarios; limited to single stream transmission). The number of time slots within a subframe is based on the time slot configuration and the digital scheme. For slot configuration 0, different digital schemes μ0 to 5 allow 1, 2, 4, 8, 16, and 32 slots per subframe, respectively. For slot configuration 1, different digital schemes 0 to 2 allow 2, 4, and 8 slots per subframe, respectively. Therefore, for slot configuration 0 and digital scheme μ, there are 14 symbols per slot and 2 per subframe. μ time slots. The subcarrier spacing and symbol length / duration are functions of the digital scheme. The subcarrier spacing can be equal to 2 μ× 15kHz, where μ is the digital scheme 0 to 5. Therefore, digital scheme μ=0 has a subcarrier spacing of 15kHz, and digital scheme μ=5 has a subcarrier spacing of 480kHz. The symbol length / duration is inversely proportional to the subcarrier spacing. Figures 2A-2D An example is provided for a slot configuration 0 with 14 symbols per slot and a 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.

[0043] The frame structure can be represented using a resource grid. Each time slot includes a resource block (RB) (also called a physical RB (PRB)), which extends 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.

[0044] like Figure 2A As shown, some REs carry reference (pilot) signals (RS) for UEs. RSs may include demodulation RSs (DM-RSs) (denoted as Rx for a particular configuration, where 100x is the port number, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RSs) for channel estimation at the UE. RSs may also include beam measurement RSs (BRSs), beam refinement RSs (BRRSs), and phase tracking RSs (PT-RSs).

[0045] Figure 2B Examples of various DL channels within a subframe of a frame are illustrated. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs), each CCE including nine RE groups (REGs), each REG including four consecutive REs in an OFDM symbol. The primary synchronization signal (PSS) may be within symbol 2 of a particular subframe of the frame. The UE 104 uses the PSS to determine the subframe / symbol timing and the physical layer identification. The secondary synchronization signal (SSS) may be within symbol 4 of a particular subframe of the frame. The SSS is used by the UE to determine the physical layer cell identification group number and the radio frame timing. Based on the physical layer identification and the physical layer cell identification group number, the UE may determine the physical cell identifier (PCI). Based on the PCI, the UE may determine the location of the above-mentioned DM-RS. The physical broadcast channel (PBCH) carrying the master information block (MIB) may be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block. The MIB provides multiple RBs in the system bandwidth and a system frame number (SFN). The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information (eg, System Information Blocks (SIBs)) not sent through the PBCH, and paging messages.

[0046] like Figure 2CAs shown, some REs carry DM-RS (denoted as R for one specific configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE can send DM-RS for the physical uplink control channel (PUCCH) and DM-RS for the physical uplink shared channel (PUSCH). The PUSCH DM-RS can be sent in the first one or two symbols of the PUSCH. The PUCCH DM-RS can be sent in different configurations, depending on whether a short PUCCH or a long PUCCH is sent and on the specific PUCCH format used. The UE can send a sounding reference signal (SRS). The SRS can be sent in the last symbol of the subframe. The SRS can have a comb structure, and the UE can send the SRS on one of the comb structures. The SRS can be used by the base station for channel quality estimation to achieve frequency-dependent scheduling on the UL.

[0047] Figure 2D An example of various UL channels within a subframe of a frame is illustrated. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indication (CQI), precoding matrix indication (PMI), rank indication (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.

[0048] Figure 33 is a block diagram of a base station 310 communicating 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 functions. 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 functions associated with broadcasting system information (e.g., MIB, SIB), 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 functions related to header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functions associated with transmission 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 functions 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.

[0049] The transmit (TX) processor 316 and the receive (RX) processor 370 implement layer 1 functions associated with various signal processing functions. Layer 1, including the physical (PHY) layer, may include error detection on the transmission channel, forward error correction (FEC) encoding / decoding of the transmission channel, interleaving, rate matching, mapping to physical channels, modulation / demodulation channels of physical channels, and MIMO antenna processing. The TX processor 316 processes the mapping to the signal constellation diagram 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 can then be divided into parallel streams. Each stream can then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., a pilot) in the time domain 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 coding and modulation schemes, as well as for spatial processing. The channel estimates may be derived from a reference signal and / or channel condition feedback sent by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318TX. Each transmitter 318TX may modulate a radio frequency (RF) carrier with a corresponding spatial stream for transmission.

[0050] At the UE 350, each receiver 354RX receives a signal through its respective antenna 352. Each receiver 354RX recovers information modulated onto an RF carrier and provides the information to a receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement layer 1 functions associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial stream destined for the UE 350. If multiple spatial streams are destined for the UE 350, they can be combined into a single OFDM symbol stream by the RX processor 356. 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 includes a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols and reference signals on each subcarrier are recovered and demodulated by determining the most likely signal constellation point sent by the base station 310. These soft decisions can be based on channel estimates calculated by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally sent on the physical channel by the base station 310. The data and control signals are then provided to the controller / processor 359, which implements Layer 3 and Layer 2 functionality.

[0051] The controller / processor 359 may be associated with a memory 360 that stores program codes and data. The memory 360 may be referred to as a computer-readable medium that may store computer-executable code for wireless communications of a user equipment (UE) that, when executed by a processor (e.g., one or more of the RX processor 356, the TX processor 368, and / or the controller / processor 359), instructs the processor to perform Fig. 9 , 10 and / or aspects of 11. In the UL, the controller / processor 359 provides demultiplexing between transport and logical channels, packet reassembly, decryption, 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.

[0052] Similar to the functions described in conjunction with the DL transmission of the base station 310, the controller / processor 359 provides RRC layer functions associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functions related to header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functions associated with transmission of upper layer PDUs, error correction through ARQ, concatenation, segmentation and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; MAC layer functions associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs to TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority processing, and logical channel priority.

[0053] The TX processor 368 may select an appropriate coding and modulation scheme and facilitate spatial processing using channel estimates derived by the channel estimator 358 from a reference signal or feedback transmitted from the base station 310. The spatial streams generated by the TX processor 368 may be provided to different antennas 352 via separate transmitters 354TX. Each transmitter 354TX may modulate an RF carrier with a corresponding spatial stream for transmission.

[0054] UL transmissions are processed at the base station 310 in a manner similar to that described in conjunction with the receiver functionality 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.

[0055] The controller / processor 375 may be associated with a memory 376 that stores program codes and data. The memory 376 may be referred to as a computer-readable medium that may store computer-executable code for wireless communications of the base station, which, when executed by a processor (e.g., one or more of the RX processor 370, the TX processor 316, and / or the controller / processor 375), instructs the processor to execute Fig. 9 , 10 and / or aspects of 11. In the UL, the controller / processor 375 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover IP packets from the UE 350. The 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.

[0056] At least one of the processor 368, the RX processor 356, and the controller / processor 359 may be configured to perform operations related to Figure 1 198 related aspects.

[0057] At least one of the processor 316, the RX processor 370, and the controller / processor 375 may be configured to perform operations related to Figure 1 199 related aspects.

[0058] In certain aspects of wireless communications, such as 5G New Radio (NR), data retransmission or repetition may be introduced as a method to increase the coverage of transmitted data. For example, if data is retransmitted or sent multiple times, the reliability and / or coverage of the transmitted data may be increased. For example, physical uplink shared channel (PUSCH) data retransmission or PUSCH repetition may increase the coverage of uplink data.

[0059] In some aspects, if the time resources allocated for PUSCH data retransmission or PUSCH repetition conflict with one or more downlink symbols, for example, as specified by the slot format indication (SFI), the PUSCH data retransmission or PUSCH repetition may not be sent or discarded. Therefore, the unsent PUSCH data retransmission or discarded PUSCH repetition is uplink data that was planned to be retransmitted or repeated but was not successfully retransmitted or repeated. In addition, the discarded or unsent PUSCH repetition may result in performance loss or coverage loss.

[0060] Some aspects of wireless communications, such as NR, may also include uplink data transmission via configured grants (CGs). These configured grant transmissions may allow uplink transmissions without dynamic grants (i.e., without DCI). In a configured grant, transmission resources may be configured for a specific device or UE, rather than dynamically scheduling for each transmission. In addition, a base station may configure a configured grant for one or more devices. Thus, a configured grant may be associated with one or more devices that share transmission resources. In some aspects, a configured grant including parameters set by a configuration may be separate from a scheduled grant. In addition, in some aspects, a DCI may activate a configured grant. In addition, an uplink data transmission with a configured grant may be sent on a configured occasion using configured resources and / or transmission parameters.

[0061] Additionally, to avoid dropping or not sending PUSCH repetitions, certain aspects of wireless communications may assign a larger nominal number of repetitions in order to account for occasional dropped repetitions. However, this may result in the uplink channel being continuously reserved for a specific beam for large data blocks or long periods of time. This may therefore result in preventing other UEs from accessing that specific data. Additionally, for some applications, latency issues may be more relaxed, and sending the dropped PUSCH repetitions later may be sufficient.

[0062] In some aspects, when a PUSCH repetition is dropped or not sent, for example, due to a downlink symbol collision, the UE may wait for the next scheduling period to send the dropped repetition. Some aspects of wireless communications may send certain PUSCH repetitions on a configured grant, for example, repetitions that were dropped due to a downlink symbol collision. However, the criteria for selecting the PUSCH resources that were dropped for transmission on the configured grant are inconsistent. The base station and the UE may benefit from more consistent criteria for selecting the transmission of the dropped PUSCH resources or the PUSCH retransmissions that were not sent. Therefore, it may be beneficial to determine criteria for selecting the transmission of the dropped PUSCH resources (e.g., via a configured grant).

[0063] Aspects of the present disclosure may include criteria for selecting transmission of discarded PUSCH resources or unsent PUSCH retransmissions, for example, via a configured grant. In fact, aspects of the present disclosure may determine whether to send discarded PUSCH resources or to send unsent PUSCH retransmissions. Aspects of the present disclosure may also select a configured grant to send discarded PUSCH resources or unsent PUSCH retransmissions. Thus, aspects of the present disclosure may determine when to send discarded PUSCH resources on a configured grant, as well as determine which configured grant may send discarded PUSCH resources.

[0064] As indicated herein, it may be selected whether to send discarded PUSCH repetitions or to send unsent PUSCH retransmissions via a configured grant. In some aspects, determining which configured grant to select for transmitting the discarded PUSCH repetitions may depend on the number of discarded PUSCH repetitions. The configured grant to be selected may also depend on the spatial relationship or quasi-co-location (QCL) assumption of the originally discarded PUSCH repetitions. Thus, among a plurality of different configured grants, the UE may select a configured grant based on the spatial relationship or QCL that matches the discarded PUSCH repetitions.

[0065] In some cases, if the number of dropped repetitions exceeds a certain threshold, this can trigger the transmission of dropped PUSCH repetitions on a configured grant. In addition, if the ratio of dropped PUSCH repetitions to the total number of PUSCH repetitions exceeds a certain threshold, this can trigger the transmission of dropped PUSCH repetitions on a configured grant. For example, if the number of dropped repetitions is greater than a certain number, such as two or three, or if the number of dropped repetitions is greater than half of the total number of repetitions, the UE may choose to retransmit by transmitting on the configured grant.

[0066] In addition, the number of discarded PUSCH resources may also affect the selection of the configured grant, for example, among multiple configured grants. So there may be multiple configured grants, and one configured grant may provide more resources or a more frequent periodicity, which may affect the selection of the configured grant. In some aspects, these criteria may be configured by the base station, for example, via RRC signaling or RRC configuration. For example, the selection of a configured grant among multiple configured grants may also depend on the timing of the discarded PUSCH repetitions and / or the configured grant timing. In some cases, the configured grant that is closest to a PUSCH repetition may be selected, for example, the last PUSCH repetition sent. In addition, if a configured grant has been selected, the spatial relationship or quasi-collocated positioning (QCL) of the original discarded repetitions may override the decision to select a specific configured grant.

[0067] In addition, certain criteria for selecting whether to send discarded PUSCH repetitions or unsent PUSCH retransmissions on a configured grant may be specified in a standard specification or configured by a base station, for example, via RRC signaling or RRC configuration according to aspects of the present disclosure. In addition, criteria for selecting a specific configured grant for transmitting discarded PUSCH repetitions may be specified in a standard specification or configured by a base station. In addition, if a PUSCH repetition is discarded based on a downlink symbol conflict and / or based on a cancellation indication from a base station (e.g., via a group common DCI (GC-DCI)), the criteria for discarded PUSCH repetitions may be applied. Therefore, aspects of the present disclosure may include a cancellation indication, which may be a group common DCI that indicates to certain UEs not to transmit over certain resources for a period of time. In some cases, these cancellation indications may also cause PUSCH repetitions to be discarded.

[0068] As indicated herein, in some aspects, the guidelines for discarded PUSCH repetitions can be selected by the base station. Thus, the base station can set criteria for discarded PUSCH repetitions and then notify the UE of these criteria. For example, the base station can notify the UE that if certain PUSCH repetitions are discarded or not sent, the UE can send these PUSCH repetitions on a certain configured grant. In some aspects, if the number of discarded PUSCH repetitions is greater than a certain threshold, such as two or three, or greater than a percentage of the total PUSCH repetitions, such as 50%, the base station can notify the UE of the discarded PUSCH repetitions. Therefore, in some aspects, the process of resolving discarded PUSCH repetitions can be predetermined or semi-statically set by the base station, that is, without any dynamic signaling between the base station and the UE.

[0069] As described above, the base station may notify the UE of the criteria for discarded PUSCH repetitions via RRC signaling or RRC configuration. In some aspects, if the criteria for discarded PUSCH repetitions are set in the standard specification, the base station may not notify the UE of these criteria. Therefore, these criteria may be semi-statically configured by the base station or included in the standard specification. In some cases, the base station may be able to adjust the criteria for discarded PUSCH repetitions based on the actual discarded PUSCH repetitions. For example, the criterion adjustment may be performed by RRC signaling or RRC configuration. In addition, the base station may send the criteria for discarded PUSCH repetitions based on spatial relationship or QCL information. For example, the spatial relationship or QCL of the original discarded repetitions may override the authorization of the previously selected configuration.

[0070] In some aspects, other transmission parameters for the discarded PUSCH repetitions may override the selected configured grant. For example, the modulation and coding scheme (MCS) or modulation of the discarded repetitions may override the configured grant carrying criteria. In addition, the configured grant may include some previous configuration regarding uplink transmissions, and the discarded PUSCH repetitions may include uplink parameters based on scheduling. In practice, if multiple criteria for uplink data repetition or retransmission conflict, one criterion may override or overrule another criterion.

[0071] Figure 4 4 is a diagram illustrating an example communication between a UE 402 and a base station 404. At 410, the base station 404 may determine a selection process for uplink transmission, wherein the selection process may include information for uplink data retransmissions. In some aspects, the information for uplink data retransmissions may be associated with transmissions of unsent PUSCH data retransmissions. In addition, the unsent PUSCH data retransmissions may correspond to data sent via a configured grant when the data cannot be retransmitted via PUSCH.

[0072] At 420, the base station 404 may identify whether the transmission of the unsent PUSCH data retransmission is via a configured grant. In some aspects, the information for uplink data retransmission may identify whether the transmission of the unsent PUSCH data retransmission is via a configured grant.

[0073] At 422, the base station 404 can select a configured grant for transmission of the unsent PUSCH data retransmissions. Additionally, the configured grant for transmission of the unsent PUSCH data retransmissions can be selected based on a timeline of transmission of the unsent PUSCH data retransmissions.

[0074] In some aspects, the selection process for uplink transmission can be based on the number of unsent PUSCH data retransmissions. In addition, the selection process for uplink transmission can be based on whether the number of unsent PUSCH data retransmissions is greater than an unsent retransmission threshold. In addition, the selection process for uplink transmission can be based on whether the ratio of the number of unsent PUSCH data retransmissions to the total number of PUSCH data retransmissions is greater than a ratio threshold.

[0075] At 430, base station 404 may send a selection procedure for uplink transmission, such as selection procedure 432, to UE 402. In some cases, the selection procedure for uplink transmission may be sent via radio resource control (RRC) signaling or RRC configuration.

[0076] At 440, UE 402 may receive a selection process for uplink transmission, such as selection process 432, from base station 404, where the selection process may include information for uplink data retransmission.

[0079] At 460, UE 402 may determine that data cannot be retransmitted via PUSCH, wherein the data determined to be unable to be retransmitted via PUSCH may correspond to an unsent PUSCH data retransmission.

[0080] At 470, UE 402 may send at least one uplink transmission, such as uplink transmission 472, to base station 404 based on the selection process for uplink transmissions. UE 402 may also send data determined not to be retransmitted via PUSCH via a configured grant.

[0081] At 480, base station 404 may monitor at least one uplink transmission from UE 402 based on a selection process for the uplink transmission.

[0082] At 490, the base station 404 may receive at least one uplink transmission from the UE 402 based on the selection process for the uplink transmission, such as uplink transmission 472. In some aspects, the at least one uplink transmission may be sent or received via a configured grant or PUSCH. In addition, the at least one uplink transmission may include multiple unsent PUSCH data retransmissions.

[0083] In some aspects, the selection process for uplink transmission can be based on spatial relationship or quasi co-location (QCL) information. In addition, the selection process for uplink transmission can be based on untransmitted PUSCH resources. The selection process for uplink transmission can also correspond to specification information. In addition, uplink data retransmissions can correspond to uplink data that is transmitted multiple times.
