HARQ-ACK with delay of physical uplink channel repetition for semi-persistent scheduling

Abstract

Apparatuses, methods, and computer-readable media for multiplexing overlapping uplink channel transmission repetitions are disclosed herein. A user equipment (UE) can determine whether a first subset of a first set of uplink channel transmission repetitions overlaps with a downlink transmission and determine whether to transmit a second subset of the first set of uplink channel transmission repetitions when the first subset overlaps with the downlink transmission. In some aspects, the second subset includes one or more uplink channel transmission repetitions that do not overlap with the downlink transmission. When it is determined that the second subset is to be transmitted, the UE can transmit, to a base station, a second set of uplink channel transmission repetitions having the first subset of the first set of uplink channel transmission repetitions and the second subset on an uplink channel. Accordingly, reliability of uplink repetitions can be improved.

[0002] This application claims the benefit of Greek patent application serial number 20200100648, filed on October 27, 2020, entitled “DELAYED SEMI-PERSISTENT SCHEDULING HARQ-ACK WITH PHYSICALUPLINK CHANNEL REPETITION”, the entire contents of which are expressly incorporated herein by reference. Technical Field

[0003] This disclosure generally relates to wireless communications, and more specifically, to a technique for semi-persistent scheduling hybrid automatic repeat request (HARQ)-acknowledgment (ACK) with delays due to physical uplink channel repetition. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that enable 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 telecommunications standards to provide a common protocol that enables different wireless devices to communicate at the city, national, regional, and even global levels. An example telecommunications standard is 5G New Radio (NR). 5G NR is part of the continuous evolution of mobile broadband promulgated by the 3rd Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the 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). These improvements can also be applied to other multiple access technologies and telecommunications standards that employ these technologies. Summary of the Invention

[0006] The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.

[0007] In uplink repetition, two PUCCH sequences can overlap with each other on at least one slot (e.g., in a slot-based procedure). A user equipment (UE) can be configured to transmit a physical uplink control channel (PUCCH) in a symbol set, and the UE can detect a dynamic grant (e.g., downlink control information (DCI) 2_0) indicating a subset of the symbol set as a downlink data transmission or other flexible downlink signaling. In other examples, the UE can detect other types of DCI (e.g., DCI 1_0 / 1_1 / 0_1) indicating a channel state information reference signal (CSI-RS) or a physical downlink shared channel (PDSCH) in a subset of the symbol set. In some approaches to facilitate uplink repetition, the UE can cancel (or drop) the PUCCH from the subset of symbols after some processing time (e.g., about two symbols from the end of the DCI) of decoding the DCI associated with the PDSCH. In some examples, in the case of PUCCH repetition, the UE can cancel only the PUCCH repetition that overlaps with the DG PDSCH. In some aspects, due to possible PUCCH collision with at least one downlink symbol or flexible symbol, the UE can avoid time division duplexing (TDD) SPS HARQ-ACK dropping. In some aspects, SPS ACK / NACK signals dropped due to dynamic slot format indication (SFI) or dynamic grant (DG), semi-static TDD can be retransmitted by the UE.

[0008] As described above, when SPS-based uplink repetition carrying HARQ-ACK information overlaps with a DG PDSCH, the uplink repetition is dropped. However, when the dropped uplink repetition carries SPS HARQ-ACK information, this approach of handling overlapping uplink repetition with SPS HARQ-ACK information requires additional resources to retransmit the downlink data.

[0009] The subject technology provides for delayed transmission of uplink repetitions, including both dropped and remaining uplink repetitions. In this regard, the subject technology improves the efficiency and reliability of uplink repetition transmission by facilitating the delay of overlapping uplink repetitions with SPS HARQ-ACK information.

[0010] In aspects of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus can be a UE. The apparatus is configured to determine whether a first subset of a first set of uplink channel transmission repetitions overlaps with at least a portion of a downlink transmission. The apparatus is further configured to determine whether to transmit a second subset of the first set of uplink channel transmission repetitions when the first subset overlaps with at least a portion of the downlink transmission, where the second subset includes one or more uplink channel transmission repetitions that do not overlap with the downlink transmission. The apparatus is further configured to transmit, to a base station, a second set of uplink channel transmission repetitions including the first subset and the second subset of the first set of uplink channel transmission repetitions on an uplink channel when it is determined that the second subset is to be transmitted, where the second set of uplink channel transmission repetitions does not overlap with the downlink transmission.

[0011] In aspects of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus can be a base station. The apparatus is configured to transmit, to a user equipment (UE), a first downlink transmission on a downlink channel, the first downlink transmission including a configuration indicating a request to retransmit a first subset of a first set of uplink channel transmission repetitions that overlap with at least a portion of a second downlink transmission. The apparatus is further configured to receive, from the UE, a second set of uplink channel transmission repetitions on an uplink channel, the second set of uplink channel transmission repetitions including the first subset of the first set of uplink channel transmission repetitions and a second subset of the first set of uplink channel transmission repetitions, the second subset including one or more uplink channel transmission repetitions that do not overlap with the second downlink transmission, where the second set of uplink channel transmission repetitions does not overlap with the second downlink transmission.

[0027] 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 can 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 can 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.

[0028] 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 can be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0029] By way of example, an element, or any portion of an element, or any combination of elements can 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 in this disclosure. One or more processors in the processing system can 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.

[0030] Accordingly, in one or more example embodiments, the functions described can be implemented in hardware, software, or any combination thereof. If implemented in software, the functions can 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 can 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), compact disk ROM (CD-ROM), diskette, hard disk, other magnetic storage devices, a magneto-optical storage device, a solid-state memory device, a floppy disk, a cassette tape, other magnetic storage devices, flash memory cards, JAVATM disks, Bernoulli cartridges, RAMs, DRAMs, BDNs, and the like, or any other medium which can be used to store the desired information in a computer-readable form.

[0031] Figure 1 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 (WW AN)) 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 can include macro cells (high power cellular base stations) and / or small cells (low power cellular base stations). The macro cells include base stations. The small cells include femtocells, picocells, and microcells.

[0032] The base stations 102 configured for 4G LTE (collectively referred to as the Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with the EPC 160 through first backhaul links 132 (e.g., S I interface). The base stations 102 configured for 5G NR (collectively referred to as the Next Generation RAN (NG-RAN)) can interface with the core network 190 through second backhaul links 184. In addition to other functions, the base stations 102 can 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 of paging information, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment trace, RAN information management (RIM), paging, delivery of warning messages, and location measurement.

[0033] The base stations 102 can wirelessly communicate with the UEs 104. Each of the base stations 102 can provide communication coverage for a respective 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 the coverage area 110 of one or more macro base stations 102. A network that includes both small cell and macro cells can be known as a heterogeneous network. A heterogeneous network can also include Home Evolved Node Bs (eNBs) (HeNBs), which can 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 can 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 can use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. The communication links can be through one or more carriers, where a carrier can be a set of

[0034] Certain UEs 104 can communicate with each other using device-to-device (D2D) communication link 158. The D2D communication link 158 can use the DL / UL WWAN spectrum. The D2D communication link 158 can use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). D2D communication can be through a variety of wireless D2D communications systems, such as for example, WiMedia, Bluetooth, ZigBee, Wi-Fi based on Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards, LTE, or NR.

[0035] The wireless communications system can further include a Wi-Fi access point (AP) 150 in communication with Wi-Fi stations (STAs) 152 via communication links 154 in a 5 GHz unlicensed frequency spectrum. When communicating in an unlicensed frequency spectrum, the STAs 152 / AP 150 can perform a clear channel assessment (CCA) prior to communicating in order to determine whether the channel is available for use.

[0036] The small cells 102' can operate in a licensed and / or an unlicensed frequency spectrum. When operating in an unlicensed frequency spectrum, the small cells 102' can employ NR and use the same 5 GHz unlicensed frequency spectrum as used by the Wi-Fi AP 150. The small cells 102' employing NR in an unlicensed frequency spectrum can enhance coverage and / or increase capacity of an access network.

[0037] The base stations 102, whether small cell 102' or large cell (e.g., macro base station), can include and / or be referred to as an eNB, gNodeB (gNB), or another type of base station. Some base stations, such as gNB 180 can operate in a traditional sub 6 GHz spectrum, in millimeter wave (mmW) frequencies, and / or near mmW frequencies in communication with the UEs 104. When the gNB 180 operates in mmW or near mmW frequencies, the gNB 180 can be referred to as a mmW base station. Extremely high frequency (EHF) is the part of the radio frequency (RF) spectrum that lies between 30 GHz and 300 GHz. It is also known as the millimeter band, since the wavelengths range from 1 to 10 millimeters. Radio waves in this band can be referred to as millimeter waves or, simply, mmW. Near mmW can extend down to a frequency of 3 GHz with a wavelength of 100 millimeters. The super high frequency (SHF) band extends between 3 GHz and 30 GHz, also referred to as the centimeter band. Frequency range bands include frequency range 1 (FR1) which includes frequency bands up to 7.225 GHz and frequency range 2 (FR2) which includes frequency bands from 24.250 GHz and up. Communications using the mmW / near mmW radio frequency (RF) band (e.g., 3 GHz - 300 GHz) has extremely high path loss and a short range. The base stations / UEs can operate within one or more frequency range bands. The mmW base station 180 can utilize beamforming 182 with the UEs 104 to compensate for the extremely high path loss and short range. The base station 180 and the UEs 104 can each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays to facilitate beamforming.

[0038] The base stations 180 can transmit to the UEs 104 in one or more transmit directions 182'. The UEs 104 can receive from the base stations 180 in one or more receive directions 182". The UEs 104 can also transmit to the base stations 180 in one or more transmit directions. The base stations 180 can also receive from the UEs 104 in one or more receive directions. The base station(s) 180 / UE(s) 104 can perform beam training to determine the best receive and transmit directions for each of the base station(s) 180 / UE(s) 104. The transmit and receive directions for the base stations 180 can or can not be the same. The transmit and receive directions for the UEs 104 can or can not be the same.

[0039] The EPC 160 can 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 can 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 can include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a PS Streaming Service, and / or other IP services. The BM-SC 170 can provide functions for MBMS user service provisioning and delivery. The BM-SC 170 can serve as an entry point for content provider MBMS transmissions, can be used to authorize and initiate MBMS Bearer Services, and can be used to schedule MBMS transmissions. The MBMS Gateway 168 can be used to

[0040] The core network 190 can 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 can 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

[0041] Base stations can 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 wireless access to the EPC 160 or core network 190 for the UEs 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 functional device. Some of the UEs 104 can be referred to as IoT devices (e.g., a parking meter, gas pump, toaster, vehicle, heart monitor, etc.). The UE 104 can 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.

[0042] Referring again to Figure 1In certain aspects, the UE 104 can include an uplink repetition retransmission component 198 configured to determine whether a first subset of a first set of uplink channel transmission repetitions overlaps with at least a portion of a downlink transmission. The uplink repetition retransmission component 198 is further configured to determine whether to transmit a second subset of the first set of uplink channel transmission repetitions when the first subset overlaps with at least a portion of the downlink transmission, where the second subset includes one or more uplink channel transmission repetitions that do not overlap with the downlink transmission. The uplink repetition retransmission component 198 is further configured to transmit, to the base station, a second set of uplink channel transmission repetitions including the first subset and the second subset of the first set of uplink channel transmission repetitions on an uplink channel when it is determined that the second subset is to be transmitted, where the second set of uplink channel transmission repetitions does not overlap with the downlink transmission.

[0043] Still referring to Figure 1 In certain aspects, the base station 102 / 180 can include an uplink repetition retransmission configuration component 199 configured to transmit, to a user equipment (UE), a first downlink transmission on a downlink channel, the first downlink transmission including a configuration indicating a request to retransmit a first subset of a first set of uplink channel transmission repetitions that overlap with at least a portion of a second downlink transmission. The uplink repetition retransmission configuration component 199 is further configured to receive, from the UE, a second set of uplink channel transmission repetitions on an uplink channel, the second set of uplink channel transmission repetitions including the first subset of the first set of uplink channel transmission repetitions and a second subset of the first set of uplink channel transmission repetitions, the second subset including one or more uplink channel transmission repetitions that do not overlap with the second downlink transmission, where the second set of uplink channel transmission repetitions does not overlap with the second downlink transmission.

[0044] Although the following description can focus on 5G NR, the concepts described herein can be applicable to other similar areas, such as LTE, LTE-A, CDMA, GSM, and other radio technologies.

[0045] Figure 2A FIG. 200 is a diagram illustrating an example of a first subframe within a 5G / NR frame structure. Figure 2B FIG. 230 is a diagram illustrating an example of DL channels within a 5G / NR subframe. Figure 2C FIG. 250 is a diagram illustrating an example of a second subframe within a 5G / NR frame structure. Figure 2Dis a diagram 280 illustrating an example of UL channels within a 5G / NR subframe. The 5G / NR frame structure can be frequency division duplex (FDD) in which for a particular set of subcarriers (carrier system bandwidth), different subcarriers are used for DL and UL transmissions, or can be time division duplex (TDD) in which for a particular set of subcarriers (carrier system bandwidth), the same subcarriers are used for both DL and UL transmissions. Figure 2A and Figure 2C In the examples provided, the 5G / NR frame structure is assumed to be TDD, with subframe 4 configured to slot format 28 (mostly DL), where D is DL, U is UL, F can be flexibly used between DL / UL, and subframe 3 configured to slot format 34 (mostly UL). While subframes 3, 4 are shown with slot formats 34, 28, respectively, any particular subframe can be configured to 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. A UE is configured to a slot format (either dynamically with DL control information (DCI), or semi-statically / statically with radio resource control (RRC) signaling) by a received slot format indicator (SFI). Note that the description infra also applies for 5G / NR frame structures that are TDD.

[0046] Other wireless communication technologies can have different frame structures and / or different channels. A frame (10 ms) can be divided into 10 equally sized subframes (1 ms). Each subframe can include one or more time slots. A subframe can also include mini-slots, which can include 7, 4, or 2 symbols. Depending on the slot configuration, each slot can include 7 or 14 symbols. For slot configuration 0, each slot can include 14 symbols, and for slot configuration 1, each slot can include 7 symbols. A symbol on the DL can be a cyclic prefix (CP) OFDM (CP-OFDM) symbol. A symbol on the UL can be a CP-OFDM symbol (for high throughput scenarios) or a discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbol (also known as single carrier frequency division multiple access (SC-FDMA) symbol) (for power limited scenarios; limited to 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 µ 0 to 4 allow for 1, 2, 4, 8, and 16 slots per subframe, respectively. For slot configuration 1, different numerologies µ 0 to 2 allow for 2, 4, and 8 slots per subframe, respectively. Accordingly, for slot configuration 0 and numerology µ, there are 14 symbols per slot and 2 µ The subcarrier spacing and symbol length / duration are a function of the numerology. The subcarrier spacing can equal 2µ· 15 kHz, where µ is the numerology index (µ = 0, 1, 2, 3). The symbol length / duration is inversely related to the subcarrier spacing. That is, the larger the subcarrier spacing, the shorter the symbol length / duration, and vice versa. *15 kHz, where The parameter sets are 0 to 4. Therefore, the subcarrier spacing is 15 kHz for parameter set µ=0 and 240 kHz for parameter set µ=4. The symbol length / duration is inversely proportional to the subcarrier spacing. Figures 2A-2D An example of slot configuration 0 is provided, with 14 symbols per slot and parameter set µ=2, and 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 the frame set, there may be one or more different bandwidth portions (BWPs) that are frequency-division multiplexed (see 2B). Each BWP can have a specific parameter set.

[0047] A resource grid can be used to represent the frame structure. Each time slot consists of a resource block (RB) that extends 12 consecutive subcarriers (also known as a physical RB (PRB)). The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0048] like Figure 2A As illustrated, some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include a demodulated RS (DM-RS) (indicated as R for a specific configuration). x (where 100x is the port number, but other DM-RS configurations are possible) and the Channel State Information Reference Signal (CSI-RS) for channel estimation at the UE. RS may also include Beam Measurement RS (BRS), Beam Refinement RS (BRRS), and Phase Tracking RS (PT-RS).

[0049] Figure 2BAn example of various DL channels 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. A PDCCH within one BWP can be referred to as a control resource set (CORESET). Additional BWPs can be located in higher and / or lower frequencies of the channel bandwidth. A primary synchronization signal (PSS) can be within symbol 2 of particular subframes of a frame. The PSS is used by a UE 104 to determine subframe / symbol timing and physical layer identity. A secondary synchronization signal (SSS) can be within symbol 4 of particular subframes of a frame. The SSS is used by a UE to determine 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), can 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) in the time domain. The physical downlink shared channel (PDSCH) carries user data, broadcast system information such as system information blocks (SIBs), and paging messages.

[0050] As Figure 2C As illustrated in the middle, 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 can transmit DM-RS for channel estimation at the base station. The UE can transmit 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 transmitted in the first one or two symbols of a subframe. The PUCCH DM-RS can be transmitted in different configurations depending on whether short or long PUCCH is being used and depending on the particular PUCCH format used. The UE can transmit a sounding reference signal (SRS). The SRS can be transmitted in the last symbol of a subframe. The SRS can have a comb-2 structure, and the UE can transmit SRS on one of the combs. The SRS can be used by a base station for channel quality estimation to enable frequency-dependent scheduling on the UL.

[0051] Figure 2DAn example of various UL channels within a subframe of a frame is shown. The PUCCH can be positioned as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI), and hybrid automatic repeat request (HARQ) ACK / NACK feedback. The PUSCH carries data, and can additionally be used to carry buffer status reports (BSRs), power headroom reports (PHRs), and / or UCI.

[0052] In uplink repetition, two PUCCH sequences can overlap with each other on at least one slot (e.g., in a slot-based procedure). A UE can be configured to transmit a PUCCH in a set of symbols, and the UE can detect a dynamic grant (e.g., DCI 2_0) indicating a subset of the set of symbols as a downlink data transmission or other flexible downlink signaling. In other examples, the UE can detect other types of DCI (e.g., DCI 1_0 / 1_1 / 0_1) indicating a CSI-RS or PDSCH in a subset of the set of symbols. In some approaches to facilitate uplink repetition, the UE can cancel (or drop) the PUCCH from the subset of symbols after some processing time (e.g., about two symbols from the end of the DCI) of decoding the DCI associated with the PDSCH. In some examples, in the case of PUCCH repetition, the UE can only cancel the PUCCH repetition that overlaps with the DG PDSCH. In some aspects, the UE can avoid SPS HARQ-ACK dropping for TDD due to possible PUCCH collision with at least one downlink symbol or flexible symbol. In some aspects, a SPS ACK / NACK signal dropped due to dynamic SFI or dynamic grant (DG), semi-static TDD can be retransmitted by the UE. As described above, when an SPS-based uplink repetition carrying HARQ-ACK information overlaps with a DG PDSCH, the uplink repetition is dropped. However, when the dropped uplink repetition carries SPS HARQ-ACK information, the approach of dropping the uplink repetition with overlapping SPS HARQ-ACK information requires additional resources to retransmit the downlink data.

[0053] The subject technology provides for delayed transmission of uplink repetitions, including both dropped and remaining uplink repetitions. In this regard, the subject technology improves the efficiency and reliability of uplink repetition transmission by facilitating the delay of uplink repetitions with overlapping SPS HARQ-ACK information.

[0054] Figure 3is a block diagram of a base station 310 that communicates with the UE 350 in an access network. In the DL, IP packets from the EPC 160 can 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

[0055] 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, can include error detection on the transport channels, forward error correction (FEC) coding / decoding of the transport channels, interleaving, rate matching, mapping to 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 can then be split into parallel streams. Each stream can then be mapped to a 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 can be used to determine the coding and modulation schemes, as well as for spatial processing. The channel estimate can be derived from a reference signal and / or channel condition feedback transmitted by the UE 350. Each spatial stream can then be provided to a different antenna 320 via a separate transmitter 318TX. Each transmitter 318TX can modulate an RF carrier with a respective spatial stream for transmission.

[0056] 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 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 can 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 can 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 can be based on channel estimates computed by the channel estimator 358. The soft decisions are then decoded and de-interleaved 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.

[0057] The controller / processor 359 can be associated with a memory 360 that stores program codes and data. The memory 360 can 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.

[0058] 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, reassembly of RLC SDUs, concatenation, segmentation, and reassembly of RLC data PDUs, 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.

[0059] The TX processor 368 can use channel estimates derived by the channel estimator 358 from a reference signal or feedback transmitted by the base station 310 to select an appropriate coding and modulation scheme and facilitate spatial processing. The spatial streams generated by the TX processor 368 can be provided to different antenna 352 via separate transmitters 354TX. Each transmitter 354TX can modulate an RF carrier with a respective spatial stream for transmission.

[0060] 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.

[0061] The controller / processor 375 can be associated with a memory 376 that stores program codes and data. The memory 376 can 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 can 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.

[0062] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 can be configured to perform aspects related to the 198. Figure 1

[0063] At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 can be configured to perform aspects related to the 199. Figure 1

[0064] Figure 4 is a diagram illustrating an example 400 of an uplink repetition sequence with dropped repetitions in accordance with some aspects of the present disclosure. The example 400 includes a first SPS PDSCH 402, a PDCCH 404, and a DG PDSCH 406. The example 400 illustrates a first set of uplink channel transmission repetitions including uplink repetitions 410, 412, 414, 416. The UE can determine that the uplink repetition 412 overlaps with at least a portion of the DG PDSCH 406. Thus, the sequence consisting of the uplink repetitions 412, 414, 416 can be dropped due to one overlapping repetition (e.g., 412).

[0065] ​​In some aspects, user equipment can avoid time division duplex (TDD) SPS HARQ-ACK dropping due to possible PUCCH collision with at least one downlink symbol or flexible symbol. In some aspects, SPS ACK / NACK signals dropped due to dynamic slot format indication (SFI) or dynamic grant (DG), semi-static TDD can be retransmitted by the user equipment. In some aspects, retransmission of dropped SPS A / N can occur according to UE-based implicit rules, where dropped SPS A / N can be delayed until a first available uplink symbol can accommodate PUCCH resources. For example, the earliest uplink symbol can be the earliest available occasion without any downlink transmission and / or symbol overlap in the configured occasion set, which can correspond to configured PUCCH / PUSCH resources (e.g., symbols 10 and 11 in each slot). In other examples, a base station (e.g., gNB) can indicate multiple k1 values through SPS signaling. For each SPS PDSCH, the UE can select the first k1 value that results in a valid PUCCH resource. In other examples, the base station 120 / 180 can use a Type 3 codebook to request retransmission of dropped SPS A / N. For example, the base station can request the user equipment to send ACK / NACK for SPS HARQ identifiers with dropped ACK / NACK. In another example, the base station can request the user equipment to send ACK / NACK for all SPS HARQ identifiers. In some aspects, a first subset of PUCCH repetitions can be dropped and a second subset of PUCCH repetitions can be preserved. In some aspects, the base station 120 / 180 can enable a feature to retransmit dropped SPS ACK / NACK such that the first subset of PUCCH repetitions can be retransmitted based on an indication from the base station. In other aspects, the user equipment can determine whether to retransmit remaining uplink repetitions in case of dropping at least one original uplink repetition. In some aspects, the user equipment determines a location of the retransmitted uplink repetitions.

[0066] Figure 5 FIG. 5 is a diagram illustrating an example 500 of a sequence of transmitted uplink repetitions according to some aspects of the present disclosure. The example 500 includes a first SPS PDSCH 502, a PDCCH 504, and a DG PDSCH 506. The example 500 illustrates a first set of uplink channel transmission repetitions including uplink repetitions 510, 512, 514, 516. The UE can determine that the uplink repetition 512 overlaps with at least a portion of the DG PDSCH 506. Accordingly, the sequence consisting of uplink repetitions 512, 514, 516 is dropped due to one overlapping repetition (e.g., 512).

[0067] In some aspects, the dropped uplink repetition sequence can be delayed and retransmitted at a later time based on a first available symbol that can accommodate the dropped uplink repetition. In some aspects, a user device can receive, from a base station on a downlink channel, control information indicating a resource allocation, a predetermined repetition pattern, and a starting position of each repetition occasion (e.g., 520, 522, 524, 526) for a second uplink channel transmission repetition set. In some aspects, the user device can delay transmission of the second uplink channel transmission repetition set to a starting repetition occasion based on the resource allocation. In some aspects, the starting repetition occasion includes one or more first available uplink symbols corresponding to configured uplink physical channel resources. In some aspects, the user device can delay each uplink channel transmission repetition in the second uplink channel transmission repetition set to a specified position within each repetition occasion of a number of repetition occasions corresponding to a number of repetitions out of a total number of repetitions in the second uplink channel transmission repetition set. In some aspects, each uplink channel transmission repetition in the second uplink channel transmission repetition set has one or more of a same time position or a same frequency position of a respective repetition occasion based on the predetermined repetition pattern. For example, the uplink repetitions can be delayed to the last symbol of each slot spanning four slots starting from the slot number containing the DG PDSCH 506.

[0068] Figure 6 FIG. 6 is a diagram illustrating another example 600 of a sequence of transmitted uplink repetitions in accordance with some aspects of the present disclosure. Example 800 includes a first SPS PDSCH 602, a PDCCH 604, and a DG PDSCH 606. Example 600 illustrates a first uplink channel transmission repetition set including uplink repetitions 610, 612, 614, 616. The UE can determine that uplink repetition 612 overlaps with at least a portion of the DG PDSCH 606. Thus, the sequence consisting of uplink repetitions 612, 614, 616 is dropped due to one overlapping repetition (e.g., 612).

[0069] In some aspects, the dropped uplink repetition sequence can be delayed and retransmitted at a later time based on the K1 parameter configuration. In some aspects, a user device can receive, from a base station over a downlink channel, control information indicating a predetermined repetition pattern and a plurality of K1 parameter values associated with a downlink data transmission (e.g., DG PDSCH 606) through SPS signaling (e.g., RRC signaling). In some aspects, each of the plurality of K1 parameter values includes a different time offset between the downlink data transmission and an associated uplink transmission. The user device can select a first K1 parameter value from the plurality of K1 parameter values that provides a number of repetition occasions with valid uplink resources for a total number of repetitions in a second set of uplink channel transmission repetitions. For example, for each SPS PDSCH (e.g., SPS PDSCH 602), the user device can select a first K1 parameter value that results in valid PUCCH resources for all of the uplink repetitions. As Figure 6 As illustrated in FIG. 7, the K1 parameter value is 4 with no dropped uplink repetitions. In some aspects, the user device can delay transmission of a second set of uplink channel transmission repetitions (e.g., uplink repetitions 620, 622, 624, 626) to a starting repetition occasion in a number of repetition occasions based on the first K1 parameter value. In some aspects, each uplink channel transmission repetition in the second set of uplink channel transmission repetitions can have one or more of a same time position or a same frequency position of a respective repetition occasion based on the predetermined repetition pattern.

[0070] Figure 7 is a diagram illustrating an example 700 of a single transmitted uplink repetition in accordance with some aspects of the present disclosure. Example 700 includes a first SPS PDSCH 702, a PDCCH 704, and a DG PDSCH 706. Example 700 illustrates a first set of uplink channel transmission repetitions including uplink repetitions 710, 712, 714, 716. The UE can determine that uplink repetition 712 overlaps with at least a portion of the DG PDSCH 706. Accordingly, uplink repetition 712 can be dropped, while the remaining uplink repetitions 710, 714, and 716 remain active and do not overlap with the DG PDSCH 706. In other aspects, the sequence of uplink repetitions 710, 712, 714, and 716 can be dropped as a whole due to the overlapping uplink repetition 712.

[0071] In some examples, uplink repetition 712 can be represented as part of a first subset, and uplink repetitions 710, 714, and 716 can be represented as part of a second subset, where uplink repetitions 710-716 can be represented as a first set of uplink channel transmission repetitions. In some aspects, a second set of uplink channel transmission repetitions (including the first subset and excluding the second subset) can be transmitted with the same number of dropped repetitions as the first subset of the first set of uplink channel transmission repetitions. As Figure 7 As illustrated in FIG. 8, uplink repetition 720 is transmitted based on its correspondence to a single dropped uplink repetition (e.g., 712) of uplink repetitions 710-716.

[0072] Figure 8 is a diagram illustrating an example 800 of a single transmitted uplink repetition taking into account processing time, according to some aspects of the present disclosure. Example 800 includes a first SPS PDSCH 802, a PDCCH 804, and a DG PDSCH 806. Example 800 illustrates a first set of uplink channel transmission repetitions including uplink repetitions 810, 812, 814, 816. The UE can determine that uplink repetition 812 overlaps with at least a portion of the DG PDSCH 806. Thus, the sequence consisting of uplink repetitions 812, 814, 816 is dropped due to one overlapping repetition (e.g., 812). In use cases for retransmission of dropped SPS A / Ns according to UE-based implicit rules, a UE-based determination can be performed as to whether to retransmit the SPS A / N with dropped at least one original uplink repetition for PUCCH repetitions. In some aspects, the SPS A / N is not retransmitted if any uplink repetition of the original PUCCH repetition has already been transmitted. For example, due to the UE processing timeline for the UE to decode the DG scheduling (e.g., DCI scheduling) overlaps with the 2nd PUCCH repetition after the 1st repetition has already been transmitted.

[0073] As Figure 8As illustrated in the middle, the user equipment can receive, from the base station, a first SPS PDSCH 802 (associated with uplink repetitions) at a first time, a PDCCH 804 associated with a DG PDSCH 806 at a second time, and the DG PDSCH 806 at a third time on a downlink channel. In some aspects, in response to the SPS PDSCH 802, the user equipment can transmit, to the base station, a first uplink repetition 810 of a second set of uplink channel transmission repetitions (e.g., uplink repetitions 810, 812, 814, 816) on an uplink channel at a fourth time prior to the third time. In some aspects, the second time and the fourth time are separated by a timeline. In some aspects, the user equipment can determine whether a processing time to decode the control information exceeds the timeline. In some aspects, when the processing time exceeds the timeline, the user equipment can refrain from transmitting the first subset and the second subset of the second set of uplink channel transmission repetitions. As Figure 8 As illustrated in the middle, the uplink repetitions 812, 814, 816 of the uplink repetition 810 have been transmitted prior to the completion of the processing time to decode the PDCCH 804.

[0074] Figure 9 is a diagram illustrating an example 900 of a sequence of transmitted uplink repetitions with an extended repetition pattern, in accordance with some aspects of the present disclosure. The example 900 includes a first SPS PDSCH 902, a first PDCCH 904, and a DG PDSCH 906. The example 900 illustrates a first set of uplink channel transmission repetitions including uplink repetitions 910, 912, 914, 916. The UE can determine that the uplink repetition 912 overlaps with at least a portion of the DG PDSCH 906. Thus, the sequence consisting of the uplink repetitions 910, 912, 914, 916 is discarded due to one overlapping repetition (e.g., 912).

[0075] In some aspects, the user equipment can receive, from the base station, control information indicating a resource allocation on a downlink channel. In some aspects, the user equipment can determine, based on the resource allocation, that a quantity of uplink repetition occasions corresponding to a quantity of discarded repetitions in the first subset are available to accommodate the plurality of discarded repetitions in the first subset. In some aspects, the second set of uplink channel transmission repetitions is transmitted with a first quantity of repetition occasions that is greater than a second quantity of repetition occasions used in the first set of uplink channel transmission repetitions. As Figure 9 As illustrated in the middle, the first set of uplink channel transmission repetitions (e.g., uplink repetitions 910, 912, 914, 916) includes four repetition occasions, while the second set of uplink channel transmission repetitions (e.g., 920, 922, 924, 926) includes at least five repetition occasions.

[0076] In use cases for retransmission of dropped SPS A / Ns according to UE-based implicit rules, if it is determined that SPS A / Ns with at least one dropped original uplink repetition are retransmitted, the retransmitted SPS A / Ns in PUCCH repetitions can also extend the original repetition number until one or more uplink repetition occasions become available to accommodate the retransmitted uplink repetition number. For example, if the original repetition number is 4, and the second and third uplink repetitions are dropped, the user equipment can extend the original uplink repetition number based on the original uplink repetition pattern until two repetition occasions are available to accommodate two retransmitted uplink repetitions, which can not need to be in contiguous occasions.

[0077] Figure 10 FIG. 10 is a diagram illustrating an example 1000 of a dropped uplink repetition sequence taking into account an expiration time, according to some aspects of the present disclosure. The example 1000 includes a first SPS PDSCH 1002, a first PDCCH 1004, a DG PDSCH 1006, a second PDCCH 1008, and a second SPS PDSCH 1010. The example 1000 illustrates a first set of uplink channel transmission repetitions including uplink repetitions 1020, 1022, 1024, 1026. The UE can determine that the uplink repetition 1022 overlaps with at least a portion of the DG PDSCH 1006. In some aspects, the UE can be configured to transmit the uplink repetitions such that any retransmitted uplink repetitions can not occur after the expiration time, e.g., before the start of the next SPS occasion. For example, the length of the expiration time can extend from the start of the first SPS occasion (e.g., at the start of the PDCCH 1004) to the start of the second SPS occasion (e.g., at the start of the PDCCH 1008).

[0078] In some aspects, the user equipment can determine whether one or more uplink channel transmission repetitions in the second set of uplink channel transmission repetitions are scheduled to occur before a predetermined expiration time. In some aspects, the user equipment can determine that one or more uplink channel transmission repetitions (e.g., uplink repetitions 1030, 1032, 1034, 1036) in the second set of uplink channel transmission repetitions are scheduled to not occur before the predetermined expiration time. Thus, the uplink repetition sequence is dropped since the expiration time has been exceeded. In this regard, the user equipment can refrain from transmitting the uplink channel transmission repetitions 1030, 1032, 1034, 1036, including the uplink repetition 1036 that is scheduled to not occur before the predetermined expiration time.

[0079] Figure 11is a flowchart of a process 1100 for multiplexing overlapping uplink channel transmission repetition at a user equipment for wireless communications according to some aspects of the present disclosure. The process 1100 can be performed by a user equipment (e.g., the UE 104; the UE 350, the RSU 107). As illustrated, the process 1100 includes a number of enumerated steps, but embodiments of the process 1100 can include additional steps before, after, and in between the enumerated steps. In some embodiments, one or more of the enumerated steps can be omitted or performed in a different order.

[0080] At 1102, the user equipment can determine whether a first subset of the first set of uplink channel transmission repetitions overlaps with at least a portion of a downlink transmission. The user equipment can determine whether the first subset overlaps, for example, as described in connection with Figures 1-6 At 1102, the user equipment can determine whether a first subset of the first set of uplink channel transmission repetitions overlaps with at least a portion of a downlink transmission. The user equipment can determine whether the first subset overlaps, for example, as described in connection with Figure 3 At 1102, the user equipment can determine whether a first subset of the first set of uplink channel transmission repetitions overlaps with at least a portion of a downlink transmission. The user equipment can determine whether the first subset overlaps, for example, as described in connection with Figure 13 At 1102, the user equipment can determine whether a first subset of the first set of uplink channel transmission repetitions overlaps with at least a portion of a downlink transmission. The user equipment can determine whether the first subset overlaps, for example, as described in connection with

[0081] At 1104, the user equipment can determine whether to transmit a second subset of the first set of uplink channel transmission repetitions when the first subset overlaps with at least a portion of the downlink transmission, the second subset including one or more uplink channel transmission repetitions that do not overlap with the downlink transmission. The user equipment can determine whether to transmit the second subset, for example, as described in connection with Figures 1-6 At 1104, the user equipment can determine whether to transmit a second subset of the first set of uplink channel transmission repetitions when the first subset overlaps with at least a portion of the downlink transmission, the second subset including one or more uplink channel transmission repetitions that do not overlap with the downlink transmission. The user equipment can determine whether to transmit the second subset, for example, as described in connection with Figure 3 At 1104, the user equipment can determine whether to transmit a second subset of the first set of uplink channel transmission repetitions when the first subset overlaps with at least a portion of the downlink transmission, the second subset including one or more uplink channel transmission repetitions that do not overlap with the downlink transmission. The user equipment can determine whether to transmit the second subset, for example, as described in connection with Figure 13 At 1104, the user equipment can determine whether to transmit a second subset of the first set of uplink channel transmission repetitions when the first subset overlaps with at least a portion of the downlink transmission, the second subset including one or more uplink channel transmission repetitions that do not overlap with the downlink transmission. The user equipment can determine whether to transmit the second subset, for example, as described in connection with

[0082] At 1106, the user equipment can transmit, to the base station, a second set of uplink channel transmission repetitions including the first subset of the first set of uplink channel transmission repetitions and the second subset on an uplink channel when it is determined that the second subset is to be transmitted. In some aspects, the second set of uplink channel transmission repetitions does not overlap with the downlink transmission. The user equipment can transmit the second set of uplink channel transmission repetitions, for example, as described in connection with Figures 1-6described. For example, 1106 can be performed by the one or more components described with respect to Figure 3 the first subset and the second subset of the second set of uplink channel transmission repetitions can be transmitted, for example, by the transmission component 1334 of the apparatus 1302 in FIG. 13 via the one or more components described with respect to Figure 13 the first subset and the second subset of the second set of uplink channel transmission repetitions can be transmitted, for example, by the transmission component 1334 of the apparatus 1302 in FIG. 13 via the one or more components described with respect to

[0083] In some aspects, a user equipment can receive, from a base station, a configuration on a downlink channel indicating a request to resend one or more uplink channel transmission repetitions that overlap with at least a portion of a downlink transmission. In some aspects, the user equipment can transmit, to the base station, a second set of uplink channel transmission repetitions having a first subset on an uplink channel based on the configuration, where the second set of uplink channel transmission repetitions excludes a second subset when the second subset is determined to not be transmitted.

[0084] In some aspects, a user equipment can receive, from a base station, a configuration on a downlink channel indicating a request to resend one or more uplink channel transmission repetitions that overlap with at least a portion of a downlink transmission and to transmit one or more uplink channel transmission repetitions that do not overlap with the downlink transmission. In some aspects, the user equipment can determine whether to transmit the second subset by determining to transmit the second subset based on the configuration.

[0085] In some aspects, the user equipment can determine that the first subset includes a quantity of dropped repetitions. The user equipment can determine whether the quantity of dropped repetitions exceeds a quantity threshold. In some aspects, the user equipment can refrain from transmitting the first subset and the second subset of the first set of uplink channel transmission repetitions when the quantity of dropped repetitions does not exceed the quantity threshold. In some aspects, the user equipment can transmit the second set of uplink channel transmission repetitions by transmitting, to the base station, the second set of uplink channel transmission repetitions having the first subset and the second subset on an uplink channel when the quantity of dropped repetitions exceeds the quantity threshold. In some aspects, the user equipment can receive a configuration from the base station on a downlink channel indicating the quantity threshold via semi-static or dynamic signaling.

[0086] In some aspects, the user equipment can determine that the first set of uplink channel transmission repetitions includes a total number of repetitions. The user equipment can determine that the first subset includes a number of dropped repetitions. In some aspects, the user equipment can determine a percentage of dropped repetitions based on the number of dropped repetitions and the total number of repetitions. The user equipment can determine whether the percentage of dropped repetitions exceeds a percentage threshold. In some aspects, the user equipment refrains from transmitting the first subset and the second subset of the first set of uplink channel transmission repetitions when the percentage of dropped repetitions does not exceed the percentage threshold. In some aspects, the user equipment can transmit the second set of uplink channel transmission repetitions by transmitting, to the base station, the second set of uplink channel transmission repetitions with the first subset and the second subset on the uplink channel when the percentage of dropped repetitions exceeds the percentage threshold.
