Technical Field

[0003] Aspects of the present invention generally relate to wireless communications and techniques and apparatus for combining feedback indications and feedback transmissions. 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 that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). 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, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BS) that can support communication for multiple user equipments (UEs). The UE may communicate with the base station BS via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in detail herein, the BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at the city, country, region, and even global level. NR, which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and better integrating with other open standards that use orthogonal frequency division multiple access (OFDMA) on the downlink (DL), orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink (DL), and CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple input multiple output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful. Summary of the invention

[0024] The various aspects of the present invention will be described more fully below with reference to the accompanying drawings. However, the present invention can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function proposed herein. On the contrary, these aspects are provided so that the present invention will be thorough and complete, and the scope of the content of the present invention will be fully conveyed to those skilled in the art. Based on the teachings of this article, it should be understood by those skilled in the art that the scope of the present invention is intended to cover any aspect of the content of the present invention disclosed herein, whether implemented independently of any other aspect of the present invention or implemented in combination with any other aspect of the present invention.

It should be understood that any aspect of the content of the present invention disclosed herein can be embodied by one or more elements of the claims.

[0025] Several aspects of telecommunication systems will now be described with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a 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.

[0026] It should be noted that although various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs beyond 5G (e.g., 6G).

[0027] Figure 1 is a diagram showing an example of a wireless network 100 according to the present invention. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, etc. The wireless network 100 may include a plurality of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE), and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each base station may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0028] Base stations may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., within a radius of several kilometers) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow unrestricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS. In Figure 1 In the example shown, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0029] In some aspects, the cell is not necessarily stationary, and the geographic area of ​​the cell can move according to the location of the mobile BS. In some aspects, the BS can use any suitable transmission network to interconnect with each other and / or to one or more other BSs or network nodes in the wireless network 100 through various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0030] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that is capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, relay base station, relay, or the like.

[0031] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, etc. These different types of BSs may have different transmit power levels, different coverages, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0032] A network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other, directly or indirectly, such as via a wireless or wired backhaul.

[0033] UE 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0034] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node may provide a connection to a network via a wired or wireless communication link, or provide a connection to a network (e.g., a wide area network such as the Internet or a cellular network). Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premise equipment (CPE). UE 120 may be included in a housing that houses components of UE 120 (e.g., processor components and / or memory components). In some aspects, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0035] Generally speaking, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0036] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using point-to-point (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol or vehicle-to-infrastructure (V2I) protocol), and / or mesh network. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations performed by base station 110 as described elsewhere herein.

[0037] The devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various levels, frequency bands, channels, etc. according to frequency or wavelength. For example, the devices of the wireless network 100 can communicate using an operating frequency band having a first frequency range (FR1), which can be from 410 MHz to 7.125 GHz, and / or can communicate using an operating frequency band having a second frequency range (FR2), which can be from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "below 6 GHz" frequency band. Similarly, FR2 is often referred to as a "millimeter wave" frequency band, although it is different from the extremely high frequency band (30 GHz-300 GHz) determined as "millimeter wave" by the International Telecommunication Union (ITU). Therefore, unless otherwise specified, it should be understood that, if used herein, the term "below 6 GHz" or the like can broadly represent frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specified, it should be understood that the term "millimeter wave" and the like, if used herein, can broadly represent frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0038] As shown above, Figure 1 is provided as an example. Other examples may be relevant to Figure 1 The description is different.

[0039] Figure 2 is a diagram illustrating an example 200 of base station 110 communicating with UE 120 in wireless network 100 according to the present invention. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0040] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212; select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE; process (e.g., encode and modulate) the data for the UE based at least in part on the (multiple) MCS selected for each UE; and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols (if applicable), and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0041] At the UE 120, antennas 252a to 252r may receive downlink signals from the base station 110 and / or other base stations, and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. The MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. The receive processor 258 may process (e.g., demodulate or decode) the detected symbols, provide decoded data for the UE 120 to the data receiver 260, and provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a channel quality indicator (CQI) parameter, etc. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0042] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0043] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmitting and / or receiving components (such as, Figure 2 One or more antenna elements of one or more components).

[0044] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. Symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, if applicable, may be further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and may be transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included within a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform various aspects of any of the methods described herein, for example, with reference to Figure 3A-5 As described.

[0045] At the base station 110, other uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and may be further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data receiver 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform various aspects of any of the methods described herein, for example, with reference to Figure 3A-5 As described.

[0046] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other (multiple) components in may perform one or more techniques associated with combining feedback indications, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) in may perform or direct e.g. Figure 4 The process of 400 Figure 5 10 and / or other processes as described herein. The memories 242 and 282 may store data and program codes for the base station 110 and the UE 120, respectively. In some aspects, the memory 242 and / or the memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when executed (e.g., directly, or after compilation, conversion and / or interpretation) by one or more processors of the base station 110 and / or the UE 120, the one or more instructions may cause the one or more processors, the UE 120 and / or the base station 110 to perform or direct the operations of the process 500, and / or other processes as described herein. Figure 4 The process of 400 Figure 5 The process 500 of , and / or the operations of other processes as described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0047] In some aspects, the UE 120 may include means for receiving (e.g., using the antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, memory 282, etc.) a bitmap identifying multiple feedback indicators for multiple uplink transmissions in downlink control information, wherein the multiple feedback indicators include more than one acknowledgment and / or negative acknowledgment; and means for retransmitting (e.g., using the controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, and / or the like) one or more of the multiple uplink transmissions based at least in part on receiving the bitmap identifying the multiple feedback indicators, etc. In some aspects, the UE 120 may include means for identifying (e.g., using the controller / processor 280) a failure associated with multiple uplink transmissions, wherein the multiple uplink transmissions are associated with multiple uplink transmission opportunities; and means for retransmitting (e.g., using the controller / processor 280, the transmit processor 264, the TX MIMO processor 266, the MOD 254, the antenna 252, and / or the like) the multiple uplink transmissions using a subsequent single uplink transmission, etc. In some aspects, such means may include in conjunction with Figure 2 One or more components of UE 120 are described.

[0048] As shown above, Figure 2 is provided as an example. Other examples may be relevant to Figure 2 The description is different.

[0049] In some communication systems, the UE may send an uplink transmission and monitor to receive feedback information indicating whether the uplink transmission is received. For example, during a physical uplink shared channel (PUSCH) opportunity, the UE may send a PUSCH communication to the BS and may monitor to receive downlink control information (DCI) from the BS indicating whether the PUSCH communication is successfully received. When at least a portion of the PUSCH is not successfully received, the BS may send a DCI for scheduling the retransmission of the PUSCH communication. For example, the BS may send a DCI for a specific hybrid automatic repeat request (HARQ) identifier associated with the PUSCH communication. In some cases, such as when the PUSCH communication is associated with multiple code block groups (CGBs) in each transport block, the DCI may include information indicating which CBGs are to be retransmitted. However, sending a DCI for each HARQ identifier may result in excessive utilization of network resources.

[0050] Some aspects described herein enable merging of feedback information. For example, the BS may merge feedback information for multiple HARQ identifiers associated with multiple PUSCH communications into a single DCI. In this case, the UE may receive a single DCI and may resend multiple PUSCH communications and / or multiple CBGs thereof based at least in part on the feedback information. In this case, the BS and the UE may reduce utilization of network resources. Additionally or alternatively, the UE may merge multiple transmissions (e.g., multiple HARQ retransmissions) into a single uplink transmission. In this case, the UE may further reduce utilization of network resources relative to sending multiple retransmissions.

[0051] Figure 3A and 3B 3 is a diagram showing an example 300 / 300' of combining feedback indication and feedback transmission according to the present invention. Figure 3A and 3B As shown, example 300 / 300 ′ may include BS 110 and UE 120 .

[0052] like Figure 3AAs further shown, and by reference numeral 310, UE 120 may receive feedback information. For example, UE 120 may receive DCI with a HARQ bitmap to identify HARQ feedback for multiple PUSCH transmission opportunities. In this case, the multiple PUSCH transmission opportunities may be a configuration authorization PUSCH opportunity, a dynamic authorization PUSCH opportunity, a combination of a configuration authorization PUSCH opportunity and a dynamic authorization PUSCH opportunity, etc. In some aspects, UE 120 may identify multiple acknowledgement messages (ACKs) and / or negative acknowledgement messages (NACKs) based at least on the DCI. For example, UE 120 may receive a single DIC with multiple bits to identify one or more ACKs, one or more NACKs, a combination of one or more ACKs and one or more NACKs, etc. In some aspects, UE 120 may identify feedback information for PUSCH transmission opportunities with different HARQ identifiers. For example, UE 120 may identify a first set of bits of a bitmap in the DCI that is associated with a first set of PUSCH transmission opportunities having a first set of HARQ identifiers, and may identify a second set of bits of a bitmap in the DCI that is associated with a second set of PUSCH transmission opportunities having a second set of HARQ identifiers.

[0053] In some aspects, UE 120 may identify feedback information for one or more transport blocks and / or CBGs for a PUSCH transmission opportunity. For example, when a PUSCH transmission opportunity has multiple transport blocks and / or multiple CBGs in each transport block, UE 120 may identify multiple bits of a bitmap of a DCI corresponding to multiple transport blocks and / or multiple CBGs.

[0054] In some aspects, UE 120 may receive a DCI indicating that no retransmissions of failed communications are to be performed. For example, UE 120 may receive a DCI with a bit set indicating an ACK set for a set of PUSCH transmission opportunities. In this case, UE 120 may determine to use the next configured authorized PUSCH transmission opportunity for new data transmission rather than for HARQ retransmissions. In some aspects, UE 120 may receive an indicator of dynamic authorization for HARQ retransmissions. For example, when the DCI includes an indicator of NACK, the DCI may include information identifying dynamic authorization resources for HARQ retransmissions of failed PUSCH transmission opportunities that correspond to the NACK.

[0055] like Figure 3A As further shown in FIG. 1 , by reference numeral 320, UE 120 may send one or more HARQ retransmissions. For example, UE 120 may send multiple HARQ retransmissions based at least in part on receiving an indicator of multiple NACKs in the DCI. Additionally or alternatively, as Figure 3BAs shown, by reference numeral 320', UE 120 may combine multiple HARQ retransmissions into a single HARQ retransmission. For example, UE 120 may retransmit multiple failed transport blocks and / or configuration grants (CGs) via a single configuration grant PUSCH transmission opportunity. In some aspects, UE 120 may retransmit in the next available configuration grant PUSCH transmission opportunity. For example, UE 120 may retransmit in any one of the configuration grant PUSCH transmission opportunities that occurs after receiving the DCI. Additionally or alternatively, UE 120 may retransmit in the next configuration grant PUSCH transmission opportunity, which is associated with an indicated subset of the configuration grant configuration identifier. For example, UE 120 may retransmit in a configuration grant PUSCH transmission opportunity, which has a configuration grant configuration identifier that is different from any failed transmission indicated in the DCI.

[0056] In some aspects, the UE 120 may use a specific set of operating parameters to send one or more HARQ retransmissions. For example, the UE 120 may use a beam identified by the DCI, a modulation and coding scheme, etc. Additionally or alternatively, the UE 120 may use the operating parameters of the previous transmission in the next configuration authorization PUSCH transmission opportunity, for which the failure triggered one or more HARQ retransmissions. In some aspects, the UE 120 may determine that the allocation of the next configuration authorization PUSCH transmission opportunity is less than the number of resources used to resend one or more HARQ retransmissions. In this case, the UE 120 may increase the configuration authorization PUSCH transmission opportunity to a size with sufficient resources to resend all of the one or more HARQ retransmissions identified by the DCI. Additionally or alternatively, the UE 120 may increase the modulation and coding scheme to resend all of the one or more HARQ retransmissions in a single configuration authorization PUSCH transmission opportunity. Additionally or alternatively, the UE 120 may maintain the size of the configuration authorization PUSCH transmission opportunity and the modulation and coding scheme. In this case, UE 120 may send a first subset of one or more HARQ transmissions in a first configured granted PUSCH opportunity and send one or more second subsets of one or more HARQ retransmissions in one or more second configured granted PUSCH opportunities.

[0057] In some aspects, the UE 120 may use the dynamically granted PUSCH transmission opportunity for one or more HARQ retransmissions. For example, when the UE 120 receives a DCI identifying the dynamically granted PUSCH transmission resources, the UE 120 may use the dynamically granted PUSCH transmission resources for one or more HARQ retransmissions. Additionally or alternatively, the UE 120 may use resources of both the configured grant and the dynamically granted. For example, when one or more HARQ retransmissions cannot be sent in the resources of a single grant, the UE 120 may use the resources of the configured grant and the dynamically granted. Alternatively, the UE 120 may use the resources of the first-arriving grant. For example, when the dynamically granted resources are scheduled before the configured granted resources, the UE 120 may use the dynamically granted resources to send one or more HARQ retransmissions.
