1 / 46 SYSTEMS AND METHODS FOR TRANSMITTING FEEDBACK INFORMATION TECHNICAL FIELD

[0001] The disclosure refers generally to wireless communications and, more specifically, to Hybrid Automatic Repeat Requests (HARQ). BACKGROUND

[0002] Current mobile networks can provide users with almost ubiquitous radio access to data transmission services. As users continue to demand ever-higher data rates, different techniques have been developed to increase the data rate and reliability of data transmissions between the network and the individual user equipment (UE). In the 5th Generation Mobile Network System (5GC), HARQ is a key technology in New Radio (NR) systems. HARQ characteristics can improve the reliability of data transmissions. SUMMARY

[0016] Several exemplary arrangements of the present solution are described below with reference to the accompanying figures to enable a person skilled in the art to create and use the present solution. As would become evident to those skilled in the art after reading this disclosure, various alterations or modifications to the examples described herein may be made without departing from the scope of this solution. Therefore, the present solution is not limited to the exemplary arrangements and applications. Petition 870250106365, dated 11 / 19 / 2025, p. 11 / 62 4 / 46 described and illustrated herein. Furthermore, the specific order or hierarchy of steps in the methods disclosed in this document are merely example approaches. Based on design preferences, the specific order or hierarchy of steps in the disclosed methods or processes may be rearranged while remaining within the scope of the present solution. Thus, those skilled in the art will understand that the methods and techniques disclosed herein present various steps or acts in a sample order, and the present solution is not limited to the specific order or hierarchy presented unless expressly indicated otherwise.

[0017] In a wireless communications system, a wireless communication device (e.g., a UE) can communicate with a network (e.g., a base station). As part of the communication process, the UE and the network can use feedback procedures (e.g., HARQ procedures) to increase the data rate and reliability of data transmissions. For example, a HARQ can be included in the Media Access Control (MAC) and Physical (PHY) layers to increase the reliability of data transmissions.

[0018] In some cases, a HARQ feedback codebook and UL data can be scheduled within the same UL time slot. The codebook and UL data can be transmitted by the UE to the network on a Physical Uplink Shared Channel (PUSCH). In some examples, UL data resources can be punched by HARQ feedback codebook resources. In some examples, UL data resources can be transmitted by rate matching with resources from a HARQ feedback codebook. For a UE scheduled to provide feedback on PUSCH, some DL transmissions or some DL transmissions scheduled by DL DCIs in DL slots after a UL grant may not be featured (e.g., included) in the feedback codebook. A UE can Petition 870250106365, dated 11 / 19 / 2025, p. 12 / 62 5 / 46 Determine the size of the HARQ feedback codebook based on a total UL Downlink Assignment Index (DAI) value. For example, a total UL DAI might be transmitted over the network along with a UL grant in a DCI message to the UE. In some cases, a number of all DL transmissions for inclusion in a feedback codebook might be indicated (e.g., in a DCI field or by the total UL DAI value). However, some wireless communication systems (e.g., NR systems) might support additional DL transmissions scheduled by DL DCIs between a feedback slot and UL grant carrying a feedback codebook.Feedback support for these additional DL transmissions (e.g., support for DL ​​transmissions before and after the UL grant slot) is provided by the arrangement disclosed here to enhance feedback procedures for DL ​​transmissions before and after a UL grant slot (e.g., a slot within a UL grant). For example, the arrangements disclosed here can support feedback information for Physical Downlink Shared Channels (PDSCH) before and after a UL grant in a UL-grant scheduled PUSCH. Feedback information allows for DL ​​scheduling after UL DCI, which can result in increased system transmission efficiency and reduced feedback delay. In some cases, DL slots after a UL grant are referred to as post-UL grant DL slots.

[0019] FIG. 1 illustrates an example of a 100 wireless communication system in which the techniques disclosed herein can be implemented, according to an implementation of the present disclosure. In the following discussion, the 100 wireless communication system can implement any wireless network, such as a cellular network or a narrowband Internet of Things (NB-IoT) network, and is referred to here as system 100. Such a system 100 of Petition 870250106365, dated 11 / 19 / 2025, page 13 / 62 Example 6 / 46 includes a base station (BS) 102 and a UE 104 that can communicate with each other via a communication link 110 (e.g., a wireless communication channel), and a cluster of cells 126, 130, 132, 134, 136, 138, and 140 overlapping a geographic area 101. In FIG. 1, BS 102 and UE 104 are located within a respective geographic boundary of cell 126. Each of the other cells 130, 132, 134, 136, 138, and 140 may include at least one BS operating in its allocated bandwidth to provide adequate radio coverage to its intended users.

[0020] For example, BS 102 can operate in an allocated channel transmission bandwidth to provide adequate coverage to UE 104. BS 102 and UE 104 can communicate via a DL 118 radio frame and a UL 124 radio frame, respectively. That is, BS 102 can send data, messages, signals, and information to UE 104 using the DL 118 radio frame, and UE 104 can send data, messages, signals, and information to BS 102 using the UL 124 radio frame. Each 118 or 124 radio frame can be further divided into a 120 or 127 sub-frame. Each radio frame can include one or more slots. Each subframe or slot may include one or more 122 or 128 data symbols. In this disclosure, BS 102 and UE 104 are described here as non-limiting examples of communication nodes, which may generally employ the methods disclosed herein.These communication nodes may be capable of wireless communication, according to various implementations of the present solution. In some implementations, the 100 wireless communication system may support MIMO communication. For example, MIMO is a key technology in NR systems. MIMO can be functional in Frequency Division Duplex (FDD) and Time Division Duplex (TDD) systems, among others.

[0021] FIG. 2 illustrates a block diagram of an example of a 200 wireless communication system for transmission and reception. Petition 870250106365, dated 11 / 19 / 2025, page 14 / 62 7 / 46 of wireless communication signals, for example, OFDM / OFDMA signals, according to some implementations of the present solution. System 200 may include components and elements configured to support known or conventional operational characteristics that do not need to be described in detail here. In an illustrative implementation, system 200 may be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment, such as the wireless communication environment 100 of FIG. 1, as described above.

[0022] System 200 generally includes a BS 202 and a UE 204. The BS 202 is an example of the BS 102. The UE 204 is an example of the UE 104. The BS 202 includes a BS 210 transceiver module, a BS 212 antenna, a BS 214 processor module, a BS 216 memory module, and a 218 network communication module, each module being coupled and interconnected as needed via a 220 data communication bus. The UE 204 includes a UE 230 transceiver module, a UE 232 antenna, a UE 234 memory module, and a UE 236 processor module, each module being coupled and interconnected as needed via a 240 data communication bus. The BS 202 communicates with the UE 204 through a communication channel 250, which may be any wireless channel or other suitable means for data transmission as described in this document.

[0023] System 200 may additionally include any number of modules other than those shown in FIG. 2. Those skilled in the art will understand that the various illustrative blocks, modules, circuits, and processing logic described in connection with the implementations disclosed herein may be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, various components, blocks, Petition 870250106365, dated 11 / 19 / 2025, page 15 / 62 8 / 46 illustrative modules, circuits, and stages are generally described in terms of their functionality. Whether such functionality is implemented as hardware, firmware, or software may depend on the specific application and the design constraints imposed on the overall system. Those familiar with the concepts described herein may implement such functionality appropriately for each specific application, but such implementation decisions should not be interpreted as limiting the scope of this disclosure.

[0024] According to some implementations, the UE 230 transceiver may be referred to herein as a UL 230 transceiver, which includes a radio frequency (RF) transmitter and an RF receiver, each including circuitry coupled to antenna 232. A duplex switch (not shown) may alternatively couple the UL transmitter or receiver to the UL antenna in time-duplex mode. Similarly, according to some implementations, the BS 210 transceiver may be referred to in this document as a downlink 210 transceiver which includes an RF transmitter and an RF receiver, each including circuitry that is coupled to antenna 212. A downlink duplex switch may alternatively couple the downlink transmitter or receiver to the downlink antenna 212 in time-duplex mode.The operations of the two transceiver modules 210 and 230 can be coordinated in time so that the UL receiver circuit is coupled to the UL antenna 232 for receiving transmissions through the wireless transmit link 250 at the same time that the downlink transmitter is coupled to the downlink antenna 212. In some implementations, there is close time synchronization with a minimum guard time between changes in duplex direction.

[0025] The UE 230 transceiver and the BS 210 transceiver are configured to communicate via the wireless data communication link 250 and cooperate with an arrangement of Petition 870250106365, dated 11 / 19 / 2025, p. 16 / 62 9 / 46 RF antenna properly configured 212 / 232 that can support a specific wireless communication protocol and modulation scheme. In some illustrative implementations, the UE 210 transceiver and the BS 210 transceiver are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G and 6G standards, and the like. It is understood, however, that the present disclosure is not necessarily limited in application to a particular standard and associated protocols. Instead, the UE 230 transceiver and the BS 210 transceiver may be configured to support alternative or additional wireless data communication protocols, including future standards or variations thereof.

[0026] According to various implementations, the BS 202 may be, for example, an evolved node B (eNB), a gNB, a service eNB, a target eNB, a femto station, a Transmit / Receive Point (TRP), a pico station, or another UE. In some implementations, the UE 204 may be composed of various types of user devices, such as a cell phone, a smartphone, a Personal Digital Assistant (PDA), a tablet, a laptop, a wearable computing device, a terminal, etc. Processor modules 214 and 236 may be implemented, or realized, with a general-purpose processor, a content-addressable memory, a digital signal processor, an application-specific integrated circuit, a field-programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described herein.Thus, a processor can be implemented as a microprocessor, a controller, a microcontroller, a state machine, or similar. A processor can also be implemented as a combination of computing devices, for example, a combination of a digital signal processor and a... Petition 870250106365, dated 11 / 19 / 2025, page 17 / 62 10 / 46 microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a digital signal processor core, or any other configuration.

[0027] Furthermore, the methods described in connection with the implementations disclosed herein can be implemented directly in hardware, in firmware, in a software module executed by the processing modules 214 and 236, respectively, or in any practical combination thereof. The memory modules 216 and 234 can be implemented as RAM, flash memory, ROM, EPROM, EEPROM, registers, hard disk, removable disk, CD-ROM, or any other form of storage known in the art. In this respect, the memory modules 216 and 234 can be coupled to the processing modules 210 and 230, respectively, so that the processing modules 210 and 230 can read information from and write information to the memory modules 216 and 234, respectively. The memory modules 216 and 234 can also be integrated into their respective processing modules 210 and 230.In some implementations, memory modules 216 and 234 may each include a cache memory to store temporary variables or other intermediate information during the execution of instructions to be executed by processor modules 210 and 230, respectively. Memory modules 216 and 234 may also include non-volatile memory to store instructions to be executed by processor modules 210 and 230, respectively.

[0028] The 218 network communication module generally represents the hardware, software, firmware, processing logic, and / or other components of the BS 202 that enable bidirectional communication between the BS 210 transceiver and other network components and communication nodes configured for communication with the BS 202. For example, the 218 network communication module can be configured to support traffic of Petition 870250106365, dated 11 / 19 / 2025, page 18 / 62 11 / 46 internet or WiMAX. In a typical deployment, without limitation, the 218 network communication module provides an 802.3 Ethernet interface so that the BS 210 transceiver can communicate with a conventional Ethernet-based computer network. In this way, the 218 network communication module can include a physical interface for connection to the computer network (e.g., Mobile Switching Center (MSC)). The terms configured for, configured to, and their conjugations, as used in this document in relation to a specified operation or function, refer to a device, component, circuit, structure, machine, signal, etc., that is physically constructed, programmed, formatted, and / or arranged to perform the specified operation or function.

[0029] FIG. 3 is a diagram illustrating an example of wireless communication method 300, according to various arrangements. The frame structure shown in relation to wireless communication method 300 includes slots 302, 304, 306, and 308 which correspond to different times. For example, slot 302 can be called slot n, slot 304 can be called slot n+1, slot 306 can be called slot n+2, slot 308 can be called slot n+ke, and so on. Wireless communication method 300 can include various transmissions using various features (e.g., time, frequency, space, code, etc.) of slots 302, 304, 306, and 308, which are transmission features. For example, slot 302 can be used by the network (e.g., BS 102) to transmit a DL DCI 310 (e.g., a first DL DCI) and a PDSCH 312 (e.g., a first PDSCH) scheduled by DL DCI 310 to UE 104.Feedback information for PDSCH 312 is indicated by DL DCI 310 to be transmitted on a Physical Uplink Control Channel (PUCCH) 320 within slot 308. Slot 304 can be used by the network to transmit a UL DCI 314 to UE 104. Slot 306 can be used by the network to transmit a... Petition 870250106365, dated 11 / 19 / 2025, page 19 / 62 12 / 46 DL DCI 316 (e.g., a second DL DCI) and a PDSCH 318 (e.g., a second PDSCH) scheduled by DL DCI 316 for UE 104. Slot 308 can be used by UE 104 to transmit a PUSCH 322 scheduled by UL DCI 314 to the network. Since PUCCH 320 is located in the same slot as PUSCH 322, the feedback information originally carried on PUCCH 320 will be transmitted on PUSCH 322.

[0030] In some cases, the 300 wireless communication method can support HARQ feedback by a UE based on a Transmission Block (TB). In some deployments using time-domain duplex (TDD) modes, a many-to-one mapping between DL transmissions (or DL ​​slots) and UL feedback resources (or UL slots) may be present. For example, multiple DL slots may correspond to one UL feedback time slot for the UE. Feedback for the multiple DL transmissions can be aggregated into a HARQ feedback codebook and transmitted on a UL transmission resource (e.g., within a PUCCH or PUSCH) to the network (e.g., BS 102). The feedback codebook may include a size that refers to a number of bits in the codebook.

[0031] In some cases, wireless communication 300 can support various conditions. For example, to provide feedback information in PUSCH, the HARQ feedback codebook and UL data can be scheduled within the same UL time slot. Both the HARQ feedback codebook and UL data can be transmitted by UE 104 to BS 102 on a UL data resource (e.g., a PUSCH). UL data resources can be punched by HARQ feedback codebook resources, or UL data resources can be transmitted by rate matching with resources from a HARQ feedback codebook. In some examples, a DL slot refers to Petition 870250106365, dated 11 / 19 / 2025, p. 20 / 62 13 / 46 refers to a slot (e.g., a time slot) with a DL assignment (e.g., for DL ​​data transmission in PDSCH). A UL slot refers to a slot with UL data transmission in PUSCH, UL HARQ feedback in PUCCH, or PUSCH. The disclosure presented here may refer to a HARQ feedback codebook as a feedback codebook or a HARQACK feedback codebook, and may refer to HARQ feedback as feedback or HARQ-ACK feedback. In some cases, the feedback codebook may be one of two types of feedback codebooks: a type 1 codebook or a type 2 codebook.

[0032] The feedback codebook size of a type 1 codebook may depend on a number of DL transmission slots corresponding to UL feedback timing slots, according to the defined feedback timing (K1) values ​​and a number of codewords for each slot and configuration of the time-domain resource allocation list. In carrier aggregation (CA) use cases, a type 1 codebook feedback codebook size may be related to a number of component carriers (CCs). BS 102 and UE 104 may have a unified (i.e., mutual) understanding of the size and bit order of the type 1 codebook feedback codebook (e.g., to avoid false retransmissions). The bit order of the type 1 codebook feedback codebook may refer to a relationship between each bit in a codebook and the associated DL slot.The type 1 codebook may include feedback information for all DL slots corresponding to the UL feedback slot in which the type 1 codebook is transmitted by UE 104. In some instances, a portion of the DL slots may not include DL data transmissions. Due to the lack of DL data transmissions, the feedback bits... Petition 870250106365, dated 11 / 19 / 2025, p. 21 / 62 14 / 46 of a feedback codebook associated with the DL slot portion may provide useless information (e.g., useless information, information unrelated to feedback, and so on).

[0033] For example, the type 2 codebook may include a DAI mechanism to determine the codebook size and bit order. In a first example, feedback information may be carried in a PUCCH. For example, DAI indication fields (e.g., a counter DAI and a total DAI) may be included in a DCI to schedule DL transmission. The counter DAI may indicate a bit order for the feedback information in the codebook. For example, the value of the counter DAI in a DL DCI may indicate the position of the feedback information within the type 2 codebook for a DL transmission scheduled by the DL DCI. The value of the total DAI in a final DL scheduling DCI may indicate the feedback codebook size. For example, the value of the total DAI may indicate the number of DL transmissions up to the current transmission (e.g., each transmission to be fed back in a type 2 codebook).A total DAI value in a final DL DCI can indicate the size of a type 2 feedback codebook.

[0034] In a second example, feedback information can be transmitted in the PUSCH. For example, a UL DAI field can be entered into a UL DCI for PUSCH scheduling. In some cases, the UL DAI value can override the total DAI value in the last DL DCI to determine the type 2 codebook size. Due to the override, after the UL DCI, other DL DCIs may not schedule other DL transmissions that are fed back into a PUSCH scheduled by the UL DCI, which can prevent the sending of unwanted feedback bits in a feedback codebook (e.g., Petition 870250106365, dated 11 / 19 / 2025, p. 22 / 62 15 / 46 as the relevant DL slots for the feedback codebook can be indicated).

[0035] DAI can increase DCI overhead as the DAI field is added to the DL and / or UL DCI. For example, PUSCH 322 in slot 308 (e.g., slot n+k) can be scheduled by UL DCI 314 in slot 304 (e.g., slot n+1). Since PUCCH 320 and PUCCH 322 overlap (e.g., overlap in time), PDSCH 312 in slot 302 (e.g., slot n), scheduled by DL DCI 310 in slot 302 and starting earlier (e.g., in time) than UL DCI 314, may be indicated to be fed back to PUCCH 320 in slot 308. Due to the indication, feedback information originally ported to PUCCH 320 may be included (e.g., added, associated, or related to) PDSCH 322. In some cases, PDSCH 318, scheduled by DL DCI 316 and starting later (e.g., in time) or not before UL DCI 314, may not be fed back to slot 308. That is, slot 308 may not include feedback information for PDSCH 318.

[0036] Some wireless communication systems can indicate UL HARQ feedback timing values. For example, in NR, a base station (BS) can indicate, to a UE, UL HARQ feedback timing values ​​(e.g., a feedback slot for transmitting a feedback codebook) via semi-static Radio Resource Control (RRC) signaling, via dynamic DCI (e.g., via a relationship between a specific slot and the feedback slot for transmitting a feedback codebook), or both. Having both options can make feedback timing, and an associated feedback codebook size, more flexible and complex than other communication standards. For example, NR can include more DL assignments (e.g., DL slots) between a UL grant slot and a feedback slot carrying a codebook. Petition 870250106365, dated 11 / 19 / 2025, page 23 / 62 16 / 46 feedback codes compared to other communication standards. The arrangement described here can support feedback for DL ​​assignments that are both before and after a UL grant slot, rather than only before the UL grant slot.

[0037] FIG. 4 is a diagram that illustrates an example of a 400 wireless communication method for transmitting feedback information, according to various arrangements. The frame structure in the 400 wireless communication method can include slots 402, 404, 406, 408, 410, 412, 414, 416, 418, and 420. For example, slot 402 could be slot n, slot 404 could be slot n+1, slot 406 could be slot n+2, slot 408 could be slot n+3, slot 410 could be slot n+4, slot 412 could be slot n+5, slot 414 could be slot n+6, slot 416 could be slot n+7, slot 418 could be slot n+8, and slot 420 could be slot n+9. The frame structure could be a TDD frame structure having a DDDSU configuration for slots 402-420, respectively. As shown in Figure 4, slots 402-410 include three DL slots, one special slot, and one UL slot, while slots 412-420 include three DL slots, one special slot, and one UL slot.Slots 402 to 420 may be associated with different transmission types; for example, slots 402, 402, 406, 412, 414, and 416 may be DL slots. Slots 410 and 420 may be UL slots. Slots 408 and 418 are special slots.

[0038] In wireless communication method 400, various transmissions can be transmitted and received using various slot features (e.g., time, frequency, space, code, etc.). For example, the network (e.g., BS 102) can use slots 402 and 404 to transmit to UE 104 the UL DCI 422 (e.g., a first UL DCI) and 424 (e.g., a second UL DCI). The network can use slots 406 and 410 to transmit to UE 104 the DL DCIs 426 (e.g., a first DL DCI) and 434 (e.g., a second DL DCI), as well as the Petition 870250106365, dated 11 / 19 / 2025, page 24 / 62 17 / 46 PDSCHs 428 (e.g., a first PDSCH) and 436 (e.g., a second PDSCH). UE 104 can use slots 410 and 420 to transmit to the network PUCCHs 430 (e.g., a first PUCCH) and 438 (e.g., a second PUCCH) and PUSCHs 432 (e.g., a first PUSCH) and 440 (e.g., a second PUSCH).

[0039] The 400 wireless communication method can support HARQ feedback. For example, feedback information for UL DCI 422 can be provided on PUSCH 432 in slot 410, and feedback information for UL DCI 424 can be provided on PUSCH 440 in slot 420. DL DCI 426 schedules PDSCH 428, and feedback information for PDSCH 428 cannot be provided on PUCCH 430 or PUCCH 438. DL DCI 434 schedules PDSCH 436, and feedback information for PDSCH 436 cannot be provided on PUCCH 438. Therefore, feedback information (e.g., HARQ acknowledgment (ACK) or negative acknowledgment (NACK)) from PDSCH receptions in slots 406 to 416 cannot be transmitted in UL slots 410 or 420, resulting in a delay of HARQ.

[0040] In some instances, push retry requests may only transmit in available UL slots. Push retry requests may continue to occupy contiguous or immediately adjacent UL slots, leaving no opportunity to transmit push requests for an extended period. As the retry factor increases (e.g., more retry requests), scheduling constraints become unacceptable for the user experience.

[0041] For codebook type 1, UE 104 does not generate unicast or multicast HARQ-ACK information for multiplexing on PUSCH transmission in response to the determination that the UL DAI for unicast is equal to zero or the UL DAI for multicast is equal to zero, respectively, unless UE 104 receives, on occasions for candidate PDSCH receptions, in which case UE 104 generates only the corresponding unicast or multicast HARQ-ACK information, 1) only a scheduling PDSCH release. Petition 870250106365, dated 11 / 19 / 2025, page 25 / 62 1) 18 / 46 semi-persistent (SPS) unicast or multicast, 2) only unicast SPS PDSCH(s) or multicast SPS PDSCH(s) having associated HARQ-ACK information reporting enabled, 3) only a Transmission Configuration Indicator (TCI) status update or a PDSCH that is scheduled by a DCI 1_0 format with a DAI field value of 1 in the Primary Cell (PCell), or 4) only a PDSCH that is scheduled by a DCI 4_1 format having the associated HARQ-ACK information reporting enabled, and the DAI field value of 1 in the PCell.

[0042] For a type 2 codebook, UE 104 does not multiplex HARQ-ACK information in the PUSCH transmission in response to the determination that 1) UE 104 does not receive a Code Block Group (CBG) configuration (e.g., via PDSCH-CodeBlockGroupTransmission), 2) UE 104 is scheduled for a PUSCH transmission by the DCI format that includes a UL DAI field with value 4, 3) UE 104 has not received any PDCCH within the monitoring occasions for a DCI format scheduling PDSCH receptions providing transport blocks with HARQ-ACK information enabled or having HARQ-ACK information associated without scheduling PDSCH receptions in any service cell c, and 4) UE 104 does not have HARQ-ACK information in response to an SPS PDSCH reception to multiplex in the PUSCH.

[0043] For codebook type 2, the UE 104 does not multiplex the HARQ-ACK information for the first sub-codebook or for the second sub-codebook, respectively, in the PUSCH transmission in response to the determination that 1) a UE 104 is supplied with the CBG configuration, 2) the UE 104 is scheduled for a PUSCH transmission by the DCI format that includes a UL DAI field with the first value 4 or with the second value 4, 3) the UE 104 has not received any PDCCH within the monitoring occasions for a format of Petition 870250106365, dated 11 / 19 / 2025, page 26 / 62 19 / 46 DCI scheduling PDSCH reception providing a transport block with HARQ-ACK information enabled or having HARQ-ACK information associated without scheduling PDSCH reception in any service cell c, and 4) UE 104 does not have HARQ-ACK information in response to an SPS PDSCH reception to multiplex into PUSCH.

[0044] In some arrangements, the transmission of feedback information for DL ​​transmissions and assignments after UL DCI includes the division of a codebook into multiple sub-codebooks. In some arrangements, the codebook (e.g., a type 1 codebook or a type 2 codebook) may be divided into two sub-codebooks.

[0045] In some examples, a first codebook sub-transaction corresponds to a first type of DL transmission that begins before or after a UL DCI, or a second type of DL transmission scheduled by DL DCI that begins before or after the UL DCI. The feedback information for the above DL transmissions is indicated or configured to be transmitted in the same slot as a UL DCI-scheduled PUSCH. The first type of DL transmission can be at least one of the following: SPS PDSCHs, SPS PDSCH release, TCI status update, and so on. The second type of DL transmission can be PDSCHs.

[0046] In some examples, a second codebook sub-type corresponds to a first type of DL transmission that begins no earlier or later than the UL DCI, or a second type of DL transmission scheduled by DL DCI that begins no earlier or later than the UL DCI. The feedback information for the above DL transmissions is indicated or configured to be transmitted in the same slot as a UL DCI-scheduled PUSCH. The first type of DL transmission can be at least one of the following: SPS PDSCHs, SPS PDSCH release, TCI status update, and Petition 870250106365, dated 11 / 19 / 2025, page 27 / 62 20 / 46 and so on. The second type of DL transmission can be PDSCHs.

[0047] FIG. 5 is a flowchart illustrating an example of a 500 wireless communication method, according to various arrangements. The 500 method can be implemented by the network (e.g., BS 102) and UE 104. At 510, the network sends DL transmissions. At 520, UE 104 receives DL transmissions. At 530, UE 104 sends feedback information for the DL transmissions in a UL transmission scheduled by a first DCI. The feedback information corresponds to a codebook, which includes at least a first sub-codebook and a second sub-codebook based on the time of receipt of a first DCI (e.g., the UL DCI). At 540, the network receives the feedback information for DL ​​transmissions in the UL transmission scheduled by the first DCI.

[0048] In some instances, DL transmissions include at least one of the following: a first DL transmission (e.g., a first type of DL transmission for the first subcodebook) starting before or not after the first DCI for the uplink transmission; a second DL transmission (e.g., a second type of DL transmission for the first subcodebook) scheduled by a second DCI (e.g., the DL DCI), the second DCI starting before or not after the first DCI; a third DL transmission (e.g., a first type of DL transmission for the second subcodebook) starting after or not before the first DCI; or a fourth DL transmission (e.g., a second type of DL transmission for the second subcodebook) scheduled by a third DCI, the third DCI starting after or not before the first DCI.In some examples, the first codebook sub-book includes at least one of the following feedback information for the first DL transmission or feedback information for the second transmission. Petition 870250106365, dated 11 / 19 / 2025, p. 28 / 62 21 / 46 DL. In some examples, the second codebook sub-book includes at least one piece of feedback information for the third DL transmission or feedback information for the fourth DL transmission.

[0049] In some arrangements, two code subbooks can be cascaded to form a feedback codebook. The cascaded code subbooks can be transmitted or multiplexed by UE 104 in PUSCH. In some arrangements, two code subbooks can be transmitted or multiplexed by UE 104 independently in PUSCH. For example, two code subbooks are encoded independently, and the transmission resources of each code subbook in PUSCH are determined according to a predefined rule, independently. In some examples, in response to insufficient resources in PUSCH to transmit both code subbooks, one code subbook is discarded according to a predefined rule, for example, a second code subbook is discarded fixedly, or a code subbook with a relatively small number of bits is discarded.

[0050] Consequently, in some arrangements, the codebook is formed by cascading the first sub-codebook and the second sub-codebook. The first sub-codebook and the second sub-codebook are cascaded and transmitted by UE 104 and received by the network. In some arrangements, the first sub-codebook and the second sub-codebook are transmitted independently by UE 104 and received by the network.

[0051] In some arrangements, each codebook sub-book contains at least one unicast transmission feedback information and one multicast transmission feedback information. The codebook is then generated by cascading different types of codebook sub-books in this order: unicast part of the first codebook sub-book, multicast part of the Petition 870250106365, dated 11 / 19 / 2025, p. 29 / 62 22 / 46 first sub-codebook, unicast portion of the second sub-codebook, and multicast portion of the second codebook. In some arrangements, the codebook cascading order may be unicast portion of the first sub-codebook, unicast portion of the second sub-codebook, multicast portion of the first sub-codebook, and multicast portion of the second codebook.

[0052] Consequently, the first codebook sub-book includes at least one piece of feedback information for a first unicast transmission transmitted over the network to the wireless communication device, or feedback information for a first multicast transmission transmitted over the network to the wireless communication device. The second codebook sub-book comprises at least one piece of feedback information for a second unicast transmission transmitted over the network to the wireless communication device, or feedback information for a second multicast transmission transmitted over the network to the wireless communication device.

[0053] In some arrangements, a UE capability is defined. The UE capability indicates whether UE 104 supports providing HARQ-ACK feedback information for DL ​​transmission no earlier or later than a UL grant in the PUSCH scheduled by the UL grant. Therefore, in some arrangements, UE 104 sends to the network, and the network receives from UE 104, an indication that UE 104 supports providing feedback information for DL ​​transmission scheduled by a DCI format, starting no earlier or later than an uplink DCI on an uplink resource scheduled by the uplink DCI. In some arrangements, UE 104 sends to the network, and the network receives from UE 104, an indication that UE 104 supports providing feedback information for DL ​​transmissions, starting no earlier or later than the DCI of Petition 870250106365, dated 11 / 19 / 2025, page 30 / 62 23 / 46 uplink in the uplink resource scheduled by the uplink DCI.

[0054] In some arrangements, if a UE 104 reports UE capability, the UE 104 may split the codebook into two or more subcodebooks, as described herein. If a UE 104 does not report UE capability above, the codebook (e.g., the feedback information contained therein) transmitted in PUSCH contains feedback information only for DL ​​transmissions initiated at or before the granting of UL, or the codebook transmitted in PUSCH contains feedback information only for DL ​​transmissions scheduled by a DCI format initiated at or before the granting of UL.

[0055] In some arrangements, BS 102 may send UE 104 an RRC signal to indicate whether UE 104 may transmit a DL transmission starting no earlier or later than a UL grant and / or to indicate or configure UE 104 to 1) provide feedback on the scheduled PUSCH by the UL grant, 2) indicate whether UE 102 may transmit a DL transmission scheduled by a DCI DL starting no earlier or later than a UL grant, and / or 3) indicate or configure UE 104 to provide feedback on the scheduled PUSCH by the UL grant. In some arrangements, BS 102 may send RRC signaling to UE 104 to indicate whether UE 104 can provide feedback information for DL ​​transmission after a UL grant, if feedback for DL ​​transmission is indicated or configured to be provided in the scheduled PUSCH by the UL grant.In response to receiving the RRC signal, UE 104 generates the codebook including the first sub-codebook and the second sub-codebook, for example, including feedback information for both DL transmissions before or not after and not before or after the UL DCI. Petition 870250106365, dated 11 / 19 / 2025, p. 31 / 62 24 / 46

[0056] In some arrangements, the sizes of the first and second codebook subbooks are determined according to the UL DAI value in the UL DCI. For example, assuming the UL DAI value is 2, the sizes of the first and second codebook subbooks might be 4*a+2 and 4*b+2, respectively. Where a and b are non-zero integers. In some examples, a is equal to b. In some examples, a is different from b.

[0057] In other words, a separate sub-codebook is defined for the feedback corresponding to the DL transmission after the UL DCI, and the feedback can be provided in the PUSCH scheduled by the UL DCI. The restriction on scheduling DL after the UL DCI is lifted, improving system transmission efficiency.

[0058] In some arrangements, the transmission of feedback information for DL ​​transmissions or assignments after the UL DCI includes the generation of the type 1 codebook. In some arrangements, the type 1 codebook to be transmitted in a PUSCH scheduled by a UL DCI may be divided into two sub-codebooks, which correspond to feedback information for DL ​​transmissions that begin before or not after the UL DCI and not before or after the UL DCI, respectively, as described herein.

[0059] In some arrangements, the size of the first codebook subbook is determined according to the value of a UL DAI in the UL DCI. In some instances, UE 104 does not generate the first codebook subbook for multiplexing on PUSCH transmission in response to the determination that the UL DAI for unicast is equal to zero or the UL DAI for multicast is equal to zero, respectively, unless UE 104 receives 1) only a unicast or multicast SPS PDSCH release, 2) only unicast SPS PDSCH(s) or multicast SPS PDSCH(s) having enabled associated HARQ-ACK information reporting, 3) only a TCI status update or a PDSCH that is scheduled by a DCI 1_0 format with a Petition 870250106365, dated 11 / 19 / 2025, pp. 32 / 62 25 / 46 counter DAI field value of 1 in PCell, or 4) only a PDSCH that is scheduled by a DCI 4_1 format having enabled the associated HARQ-ACK information report and counter DAI field value of 1 in PCell, on occasions for candidate PDSCH receptions or monitoring occasions before or after the UL DCI, in which case UE 104 generates only the corresponding unicast or multicast HARQ-ACK information.

[0060] In some arrangements, the size of the codebook (including the first sub-codebook and the second sub-codebook) is determined according to the value of a UL DAI in the UL DCI.In some instances, UE 104 does not generate the codebook for multiplexing on PUSCH transmission in response to the determination that the UL DAI for unicast is equal to zero or the UL DAI for multicast is equal to zero, unless UE 104 receives 1) only a unicast or multicast SPS PDSCH release, 2) only unicast SPS PDSCH(s) or multicast SPS PDSCH(s) having enabled associated HARQ-ACK information reporting, 3) only a TCI status update or a PDSCH that is scheduled by a DCI 1_0 format with a counter DAI field value of 1 in the PCell, or 4) only a PDSCH that is scheduled by a DCI 4_1 format having enabled associated HARQ-ACK information reporting and a counter DAI field value of 1 in the PCell, on occasions for candidate PDSCH receptions or monitoring occasions before or after the UL. DCI, in which case UE 104 generates only the corresponding unicast or multicast HARQACK information.

[0061] In some arrangements, the size of the codebook (including the first sub-codebook and the second sub-codebook) or the size of the first codebook is determined according to the value of a UL DAI in the UL DCI. More specifically, UE 104 does not generate the codebook or the first sub-codebook for multiplexing in PUSCH transmission in response to the determination that the UL DAI for Petition 870250106365, dated 11 / 19 / 2025, pp. 33 / 62 26 / 46 unicast equals zero, or the UL DAI for multicast equals zero, unless the UL scheduling timing (e.g., slot offset between UL DCI and PUSCH) indicated in UL DCI is greater than at least one value in the set of values ​​for DL ​​scheduling timing (e.g., slot offset between DL DCI and PDSCH).

[0062] In some arrangements, the size of at least one of the first subcodebook or the second subcodebook is determined according to the value of an uplink DAI in the first DCI. In some arrangements, UE 104 generates the first subcodebook to be multiplexed in the uplink transmission in response to the determination that an uplink scheduling timing indicated in the first DCI is greater than at least one value from a set of values ​​of a DL scheduling timing.

[0063] FIG. 6 is a diagram illustrating an example of a 600 wireless communication method for transmitting feedback information, according to various arrangements. The frame structure in the 600 wireless communication method may include slots 602, 604, 606, 608, 610, 612, as well as other slots. PDCCHs 614, 618, 620, and 622 are repeats. As shown in FIG. 6, assuming that the UL k2 scheduling timing is indicated as m (e.g., 3) by the UL DCI. If a UL DCI is transmitted in slot n (e.g., slot 608, PDCCH 622), the PUSCH 628 scheduled by the UL DCI is transmitted in slot n+m (e.g., slot 612). So, if at least one value in the DL scheduling timing value set (k1 set) is less than m, UE 104 generates the codebook or the first codebook sub-book for multiplexing in PUSCH transmission, regardless of the UL DAI value in UL DCI.In the example where the set k1 is {2, 3, 4, 5}, there is potential for a DL transmission in slot 610 (for example, a PDSCH 626 scheduled by PDCCH 624). The feedback from PDSCH 626 is indicated as... Petition 870250106365, dated 11 / 19 / 2025, pp. 34 / 62 27 / 46 being in slot 612 (e.g., set kl = 2). The second sub-codebook is then generated to provide this feedback. Conversely, in response to the determination that there is no value in the DL scheduling timing set (set K1) less than m, UE 104 does not generate the codebook or the first sub-codebook for multiplexing in the PUSCH transmission if the UL DAI value in the UL DCI is zero. In the example where set k1 is {4, 5, 6, 7}, there is no further DL transmission between PDCCH4 and PUSCH, meaning the second sub-codebook does not need to be generated.

[0064] In other words, the feedback corresponding to the DL transmission after the UL DCI can be provided in the PUSCH scheduled by the UL DCI. The restriction on scheduling DL after the UL DCI is released, improving the system transmission efficiency.

[0065] In some arrangements, the transmission of feedback information for DL ​​transmissions or assignments after the UL DCI includes the generation of the type 2 codebook. In some arrangements, the type 2 codebook to be transmitted in a PUSCH scheduled by a UL DCI may be divided into two sub-codebooks, which correspond to feedback information for DL ​​transmissions that begin before or not after and not before or after the UL DCI, respectively, as described herein.

[0066] In some arrangements, the size of the first codebook subbook can be determined according to the value of a UL DAI in the UL DCI. For example, if UE 104 does not receive the CBG configuration and is scheduled for a PUSCH transmission by a UL DCI that includes a UL DAI field with a value of 4, and UE 104 has not received a DL transmission (before or, at most, after receiving the UL DCI), which is indicated or configured for feedback in the PUSCH, UE 104 does not generate the first codebook subbook for multiplexing in the PUSCH transmission. A Petition 870250106365, dated 11 / 19 / 2025, p. 35 / 62 28 / 46 DL transmission can be at least one of the following: 1) any PDCCH within the monitoring occasions for a DCI format scheduling PDSCH receptions, providing transport blocks with feedback information enabled, or having associated feedback information without scheduling PDSCH receptions, or 2) SPS PDSCHs. In some arrangements, the first DCI schedules the uplink transmission, including a DAI having a first value (e.g., 4). UE 104 does not receive a DL transmission before or, at most, after receiving the first DCI. Feedback for the DL transmission is configured to be transmitted in the same time slot (e.g., in the same slot) as the uplink transmission. UE does not multiplex the first codebook subbook in the uplink transmission.

[0067] In some arrangements, the size of the codebook (including the first sub-codebook and the second sub-codebook) is determined according to the value of a UL DAI in the UL DCI. For example, if a UE 104 does not receive the CBG configuration and is scheduled for a PUSCH transmission by a UL DCI that includes a UL DAI field with a value of 4, and the UE 104 has not received a DL transmission (before or, at most, after receiving the UL DCI), which is indicated or configured for feedback in the PUSCH, the UE 104 does not generate the codebook for multiplexing in the PUSCH transmission. DL transmission can be at least one of the following: 1) any PDCCH within the monitoring occasions for a DCI format scheduling PDSCH receptions, providing transport blocks with feedback information enabled, or having associated feedback information without scheduling PDSCH receptions, or 2) SPS PDSCHs.In some arrangements, the first DCI schedules the uplink transmission, including a DAI having a first value (e.g., 4). UE 104 does not receive a DL transmission before or at the latest after receiving the... Petition 870250106365, dated 11 / 19 / 2025, pp. 36 / 62 29 / 46 first DCI. Feedback for DL ​​transmission is configured to be transmitted in the same time interval (e.g., in the same slot) as the uplink transmission. The UE does not multiplex the codebook on the uplink transmission.

[0068] In some arrangements, the size of the codebook (including the first sub-codebook and the second sub-codebook) is determined according to the value of a UL DAI in the UL DCI. For example, if a UE 104 does not receive the CBG configuration and is scheduled for a PUSCH transmission by a UL DCI that includes a UL DAI field with a value of 4, and the UE 104 has not received a DL transmission (including, before (not after) or after (not before) the UL DCI), which is indicated or configured for feedback in the PUSCH, the UE 104 does not generate the codebook for multiplexing in the PUSCH transmission. DL transmission can be at least one of the following: 1) any PDCCH within the monitoring occasions for a DCI format scheduling PDSCH receptions, providing transport blocks with feedback information enabled, or having associated feedback information without scheduling PDSCH receptions, or 2) SPS PDSCHs.

[0069] In some arrangements, if a UE 104 is scheduled for a PUSCH transmission by a UL DCI that includes a UL DAI field with a value other than 4, or if the UE 104 has received at least one DL transmission (including before (or not after) and after (not before) the UL DCI) that is indicated or configured for feedback on the PUSCH, the UE 104 generates the codebook for multiplexing on the PUSCH transmission. In some arrangements, the first DCI schedules the uplink transmission, the first DCI includes a DAI having a second value (e.g., a value other than 4), or the UE receives a DL transmission before (or not after) or after (or not before) receiving the first DCI, the feedback for the transmission of Petition 870250106365, dated 11 / 19 / 2025, pp. 37 / 62 30 / 46 DL is configured on the uplink transmission. The wireless communication device does not generate the codebook for multiplexing on the uplink transmission.

[0070] In some arrangements, if UE 104 is scheduled for a PUSCH transmission by a UL DCI that includes a UL DAI field with a value of 4, and UE 104 has not received a DL transmission before or after receiving the UL DCI, which is indicated or configured for feedback in the PUSCH, UE 104 does not generate the codebook (including the first and second sub-codebooks) for multiplexing in the PUSCH transmission. In some arrangements, the first DCI schedules the uplink transmission, including a DAI having a first value (e.g., 4). UE 104 does not receive a DL transmission before or after receiving the first DCI, which is configured to be feedback-in at the same time interval as the uplink transmission. UE does not multiplex the codebook (including the first and second sub-codebooks) in the uplink transmission.

[0071] In some arrangements, the first codebook sub-book is generated according to the UL DAI value in the UL DCI, and the second codebook sub-book is generated according to the rule for generating codebook type 1.

[0072] In some arrangements, if a UE 104 is scheduled for a PUSCH transmission by a UL DCI that includes a UL DAI field with a value other than 4, or if the UE 104 has received a DL transmission before or after receiving the UL DCI, which is indicated or configured for feedback in the PUSCH, the UE 104 generates the first codebook subbook according to the UL DAI value in the UL DCI. The second codebook subbook is generated according to the rule for codebook generation type 1. In some arrangements, the first DCI schedules the uplink transmission, the first DCI includes a DAI having a second value (e.g., other than 4), or the UE 104 receives at least one Petition 870250106365, dated 11 / 19 / 2025, pp. 38 / 62 31 / 46 DL transmission before or after receiving the first DCI. Feedback for DL ​​transmission is configured to be transmitted within the same time interval as the uplink transmission. UE 104 generates the codebook including the generation of the first sub-codebook according to an uplink DAI value from the first DCI and the generation of the second sub-codebook according to a type 1 codebook rule.

[0073] In some arrangements, if a UE 104 is scheduled for a PUSCH transmission by a UL DCI that includes a UL DAI field with a value other than 4, or if the UE 104 has received a DL transmission just before or not after receiving the UL DCI, which is indicated or configured for feedback in the PUSCH, the UE 104 only generates the first codebook subbook according to the UL DAI value in the UL DCI. The second codebook subbook is not generated. In some arrangements, the first DCI schedules the uplink transmission, the first DCI includes a DAI having a second value (e.g., other than 4), or the UE receives a DL transmission just before or not after receiving the first DCI. Feedback for the DL transmission is configured to be transmitted at the same time interval as the uplink transmission. UE 104 generates only the first codebook subbook according to the value of an uplink DAI from the first DCI.

[0074] In some arrangements, if a UE 104 is scheduled for a PUSCH transmission by a UL DCI that includes a UL DAI field with a value other than 4, or if the UE 104 has received a DL transmission only before or not after receiving the UL DCI, which is indicated or configured for feedback in the PUSCH, the UE 104 generates the first and second codebook subbooks. In some arrangements, the UE 104 receives at least one DL transmission only before or not after receiving the first DCI. Feedback for at least one DL transmission is configured. Petition 870250106365, dated 11 / 19 / 2025, pp. 39 / 62 32 / 46 to be transmitted in the same time slot as the uplink transmission. UE 104 generates the first and second codebooks.

[0075] In some arrangements, if a UE 104 has received a DL transmission only after or not before receiving the UL DCI, which is indicated or configured for feedback in the PUSCH, the UE 104 generates only the second sub-codebook. For example, the second sub-codebook is generated according to the rule for generating type 1 codebooks. In some arrangements, the UE 104 receives at least one DL transmission only after or not before receiving the first DCI. Feedback for at least one DL transmission is configured to be transmitted in the same time interval as the uplink transmission. The UE 104 generates the second sub-codebook without generating the first codebook.

[0076] In some arrangements, the generation of the second sub-codebook depends on whether UE 104 has received a DL transmission after or not before receiving the UL DCI, whose feedback is indicated or configured to be provided in the PUSCH. In some arrangements, UE 104 generates the second sub-codebook based on receiving a DL transmission after or not before receiving the first DCI. The feedback for the DL transmission is configured to be transmitted within the same time interval as the uplink transmission.

[0077] In some arrangements, if UE 104 is scheduled for a PUSCH transmission by a UL DCI that includes a UL DAI field with value 4 and UE 104 has received only one DL transmission after or not before receiving the UL DCI, whose feedback is indicated or configured to be provided in the PUSCH, UE 104 generates only the second codebook subbook. For example, the second codebook subbook is generated according to the rule for generating type 1 codebooks. Petition 870250106365, dated 11 / 19 / 2025, pp. 40 / 62 33 / 46

[0078] In some arrangements, if UE 104 is supplied with the CBG configuration, UE 104 generates the TB codebook and the CBG codebook according to a first UL DAI value for TB and a second UL DAI value for CBG, respectively. The TB codebook and the CBG codebook can be generated using the methods described herein independently. More specifically, the TB codebook includes at least one of the first TB codebook and the second TB codebook. And the CBG codebook includes at least one of the first CBG codebook and the second CBG codebook.

[0079] In other words, the feedback corresponding to the DL transmission after the UL DCI can be provided in the PUSCH scheduled by the UL DCI. The restriction on scheduling DL after the UL DCI is released, improving the system transmission efficiency.

[0080] In some arrangements, the transmission of feedback information for DL ​​transmissions or assignments after UL DCI includes the generation of the codebook in instances where the repeating PUSCH transmission is scheduled by the UL grant. In some arrangements, the codebook (e.g., a type 1 codebook or a type 2 codebook) to be transmitted in a PUSCH scheduled by a UL DCI may be split into two sub-codebooks, which correspond, respectively, to the feedback information for DL ​​transmissions initiated before (or not after) and after (not before) the UL DCI.

[0081] FIG. 7 is a diagram illustrating an example of a 700 wireless communication method for transmitting feedback information, according to various arrangements. The frame structure in the 700 wireless communication method may include slots 702, 704, 706, 708, 710 and other slots, as shown. The frame structure may be a TDD frame structure having Petition 870250106365, dated 11 / 19 / 2025, pp. 41 / 62 34 / 46 a DDDSU configuration for the slots shown. In some examples, PUSCH transmission with repetition (e.g., PUSCH 714, 716, 718, and 720) can be scheduled by a UL DCI 712. In this example, the repetition factor is 4. Thus, the four times of the PUSCH 714, 716, 718, and 720 transmissions are located within the four slots of UL 702, 704, 706, and 708, respectively.

[0082] In some arrangements, the first codebook sub-transmission is transmitted only in the initial PUSCH transmission (e.g., the first PUSCH transmission or PUSCH rep#1, shown as PUSCH 714). The second codebook sub-transmission is transmitted in a subsequent PUSCH transmission (i.e., a non-initial PUSCH transmission, such as PUSCH 716, 718, or 720). In some arrangements, the first codebook sub-transmission is received by the network (e.g., BS 102) from UE 104 in a first PUSCH transmission (e.g., 714). The second codebook sub-transmission is received by the network from UE 104 in a subsequent PUSCH transmission (e.g., PUSCH 716, 718, or 720). The subsequent PUSCH transmission is a repetition of the first PUSCH transmission and is subsequent to the first PUSCH transmission.

[0083] In some arrangements, if a DL transmission is indicated or configured to be fed back into the slot of a PUSCH transmission, the feedback information from the DL transmission will be transmitted in the PUSCH transmission. For example, the feedback information from a DL transmission indicated or configured to be provided in the slot of PUSCH rep#1 (e.g., PUSCH 714) is transmitted in PUSCH rep#1. The feedback information from another DL transmission indicated or configured to be provided in the slot of PUSCH rep#2 (e.g., PUSCH 716) is transmitted in PUSCH rep#2, and so on. In some arrangements, the network indicates or configures UE 104 to provide feedback for a DL transmission from Petition 870250106365, dated 11 / 19 / 2025, pp. 42 / 62 35 / 46 DL transmissions correspond to a time interval (e.g., a slot) of a PUSCH transmission. The network receives feedback from UE 104 for the DL transmission in the PUSCH transmission.

[0084] In some arrangements, the size of the codebook or sub-codebook transmitted in each repetition of the PUSCH transmission is determined according to the value of UL DAI in the UL DCI that schedules the PUSCH repetition. In the example where the value of UL DAI is 2, the size of the codebook or sub-codebook transmitted in the first repetition of PUSCH can be 4*n+2. The size of the codebook or sub-codebook transmitted in the second repetition of PUSCH can be 4*m+2, and so on. The parameters are neither non-zero integers. In some examples, n is equal to m. In some examples, n is different from m.

[0085] In some arrangements, the first codebook sub-transmission is transmitted only in the initial PUSCH transmission (e.g., the first PUSCH transmission or PUSCH rep#1, shown as PUSCH 714). The second codebook sub-transmission is transmitted in the last PUSCH transmission (e.g., PUSCH rep#4 or PUSCH 720). The second codebook sub-transmission contains the DL transmission feedback information, which is indicated or configured to be provided in any slot of each PUSCH repeat. The DL transmission does not begin before or after the UL grant for PUSCH repeat scheduling. In some arrangements, the first codebook sub-transmission is received by the network from UE 104 in a first PUSCH transmission (e.g., PUSCH 714), the first PUSCH transmission being the first transmission of a PUSCH repeat.The second codebook subbook is received by the network from UE 104 in a second PUSCH transmission (e.g., PUSCH 720), the second PUSCH transmission is a final transmission of the PUSCH repeat. Petition 870250106365, dated 11 / 19 / 2025, pp. 43 / 62 36 / 46

[0086] In some arrangements, the sizes of the codebook or sub-codebook transmitted in the first PUSCH transmission and in the last PUSCH transmission are determined according to the value of UL DAI in the UL DCI that schedules the PUSCH repetition. In the example where the value of UL DAI is 2, the size of the codebook or sub-codebook transmitted in the first PUSCH repetition might be 4*x+2. The size of the codebook or sub-codebook transmitted in the last PUSCH repetition might be 4*y+2, and so on. The x and y parameters are non-zero integers. In some examples, x is equal to y. In some examples, x is different from y.

[0087] In some arrangements, the DL transmission feedback information, which is indicated or configured to be fed back in the initial PUSCH transmission slot (e.g., the first PUSCH transmission or PUSCH rep#1, shown as PUSCH 714), is transmitted in PUSCH rep#1. In some arrangements, the network indicates to UE 104 that the feedback for a DL transmission from the DL transmissions corresponds to a time interval of a first PUSCH transmission (e.g., PUSCH 714). The network receives the feedback for the DL transmission from UE 104 in the first PUSCH transmission.

[0088] The DL transmission feedback information, which is indicated or configured to be provided in any slot of the non-initial PUSCH transmission (e.g., PUSCH rep#2 (716) or PUSCH rep#3 (718) or PUSCH rep#4 (720)), is transmitted in the last PUSCH transmission (e.g., PUSCH rep#4 (720)). In some arrangements, the network indicates to UE 104 that the feedback for a DL transmission from the DL transmissions corresponds to a time interval (e.g., a slot) of a subsequent PUSCH transmission (e.g., PUSCH 716, 718, 0, or 720). The subsequent PUSCH transmission is a PUSCH transmission different from the first transmission. Petition 870250106365, dated 11 / 19 / 2025, pp. 44 / 62 37 / 46 is a PUSCH repeat. The network receives feedback from UE 104 for the DL transmission in a final PUSCH transmission (e.g., PUSCH 714). The final PUSCH transmission is the last transmission of the PUSCH repeat.

[0089] In other words, the feedback corresponding to the DL transmission after the UL DCI can be provided in the PUSCH scheduled by the UL DCI. The restriction on scheduling DL after the UL DCI is released, improving the system transmission efficiency.

[0090] In some examples, two or more slots may be occupied by a PUSCH transmission or a TB, in a TB over Multiple Slots (TBoMS) schedule. As shown in Figure 7, a PUSCH or a TB is scheduled to be transmitted in four UL slots 702, 704, 706, and 708, respectively. PUSCH 714 may be part of PUSCH 1, PUSCH 716 may be part of PUSCH 2, PUSCH 718 may be part of PUSCH 3, and PUSCH 720 may be part of PUSCH 4.

[0091] In some arrangements, the first codebook sub-book is transmitted only in the PUSCH 1 part (e.g., PUSCH 714). The second codebook sub-book is transmitted in one or more subsequent PUSCH 2, 3, and 4 parts.

[0092] In some arrangements where feedback information for a DL transmission is specified or configured to be provided in a slot of a specific PUSCH part, the feedback information for the DL transmission may be transmitted in that PUSCH part. In the example where feedback information for a DL transmission is specified or configured to be provided in the slot of PUSCH part 1, the feedback information will be transmitted in PUSCH part 1. Feedback information for another DL transmission that is specified or configured to be provided in the slot of PUSCH part 2 will be transmitted in PUSCH part 2, and so on (e.g., PUSCH 716). Petition 870250106365, dated 11 / 19 / 2025, pp. 45 / 62 38 / 46

[0093] In some arrangements, the first codebook sub-transmission is transmitted only on PUSCH part 1. The second codebook sub-transmission is transmitted on the last PUSCH part, PUSCH part 4 (e.g., PUSCH 720). The second codebook sub-transmission contains the DL transmission feedback information indicated or configured to be provided on any slot of the PUSCH part other than PUSCH part 1. DL transmission does not begin before or after the granting of UL (e.g., UL DCI 712) for scheduling PUSCH 714, 716, 718, and 720.

[0094] In some arrangements where feedback information from a DL transmission is specified or configured to be provided in the PUSCH 1 slot, the feedback information is transmitted in the PUSCH 1 slot. Feedback information from a DL transmission that is specified or configured to be provided in any PUSCH slot other than PUSCH 1 (e.g., PUSCH 2, PUSCH 3, or PUSCH 4) is transmitted in the last PUSCH slot (e.g., PUSCH 4).

[0095] In some arrangements, the codebook or sub-codebook size transmitted in each part of PUSCH is determined according to the UL DAI value in the UL DCI that programs PUSCH. For example, assuming the UL DAI value is 2, the codebook or sub-codebook size transmitted in PUSCH part 1 might be 4*p+2; the codebook or sub-codebook size transmitted in PUSCH part 2 might be 4*q+2, and so on. Where p and q are non-zero integers. In some examples, p is equal to q. In others, p is different from q.

[0096] In some arrangements, the transmission of feedback information includes the generation of a type 2 codebook for DL ​​transmissions or assignments after the UL DCI. In some arrangements, the size of the type 2 codebook is determined by Petition 870250106365, dated 11 / 19 / 2025, pp. 46 / 62 39 / 46 according to at least one of the UL DAIs in the UL DCI and the total DAIs in the last DL DCI. In some arrangements, the codebook includes a type 2 codebook. The size of the codebook is determined according to at least one of an uplink DAI in the first DCI or a DAI in a last DL DCI for a DL transmission, which must be fed back within the same time interval as an uplink transmission scheduled by the first DCI.

[0097] In some arrangements, if the UL DCI starts before or after the last DL DCI, the type 2 codebook size is determined according to the total DAI in the last DL DCI. If the UL DCI does not start before or after the last DL DCI, the type 2 codebook size will be determined according to the UL DAI in the UL DCI. In some examples, at least one of the count DAI and the total DAI in the DL DCI do not start before or after the UL DCI, counting from a UL DAI value in the UL DCI.

[0098] In some arrangements, the first DCI starts before or not after the last DL DCI, and the codebook size is determined according to the DAI in the last DL DCI. In some arrangements, the first DCI starts after or not before the last DL DCI, and the codebook size is determined according to the uplink DAI in the first DCI. In some arrangements, the last DCI starts after or not before the first DCI, the DAI in a DL DCI starts after or not before the first DCI counting from a value of the uplink DAI in the first DCI.

[0099] FIG. 8 is a diagram illustrating an example of an 800 wireless communication method for transmitting feedback information, according to various arrangements. The frame structure in the 800 wireless communication method may include slots 802, 804, 806, 808, and 810. For example, slot 802 may be slot n, slot 804 may be slot n+1, slot 806 may be slot n+2, slot 808 may be slot n+3, and slot 810 may be Petition 870250106365, dated 11 / 19 / 2025, pp. 47 / 62 40 / 46 the n+4 slot. The frame structure can be a TDD frame structure having a DDDSU configuration for slots 402410, respectively. As shown in Figure 8, slots 802810 include three DL slots, one special slot, and one UL slot. Slots 802 to 810 can be associated with different transmission types; for example, slots 802, 802, and 806 are DL slots. Slot 810 is a UL slot. Slot 818 is a special slot.

[0100] In the 800 wireless communication method, various transmissions can be transmitted and received using various slot features (e.g., time, frequency, space, code, etc.). For example, the network (e.g., BS 102) can use slot 802 to transmit UL DCI 810 to UE 104. The network can use slots 804 and 806 to transmit DL DCIs 812 (e.g., a first DL DCI) and 816 (e.g., a second DL DCI) to UE 104, as well as PDSCHs 814 (e.g., a first PDSCH) and 818 (e.g., a second PDSCH). UE 104 can use slot 810 to transmit PUCCHs 820 and PUCCH 822 to the network.

[0101] The 800 wireless communication method can support HARQ feedback. For example, feedback information for UL DCI 810 can be provided on PUSCH 822 in slot 810. DL DCI 812 schedules PDSCH 814, and feedback information for PDSCH 814 is provided on PUCCH 820. DL DCI 816 schedules PDSCH 818, and feedback information for PDSCH 818 is provided on PUCCH 820.

[0102] As shown in FIG. 8, there are two DL DCIs 812 and 816 that do not start before or after UL DCI 810. Feedback for PDSCHs 814 and 818 scheduled by DL DCIs 812 and 816, respectively, is indicated as provided in slot 810 of PUSCH 822 scheduled by UL DCI 810. UE 104 generates the codebook according to the total DAI value (e.g., total DAI 2 = 4) in the last DL DCI (e.g., DL DCI 916). The codebook size can be determined as 4*p+4. Petition 870250106365, dated 11 / 19 / 2025, pp. 48 / 62 41 / 46 Since DAI is counted cyclically in units of 4, a total DAI of 4 means that the number of bits that need to be fed back is 4*p+4, and a value of p is determined by the number of DL transmissions received by UE 104.

[0103] In some arrangements, the type 2 codebook to be transmitted in a scheduled PUSCH by a UL DCI may be divided into two sub-codebooks, which correspond to feedback information for DL ​​transmissions that begin before or not after, and not before or after, the UL DCI, respectively. The size of the first sub-codebook is determined according to the UL DAI in the UL DCI. The size of the second sub-codebook is determined according to the total DAI in the last DL DCI. In some examples, at least one of the DAI count and the total DAI in the DL DCI corresponding to the second sub-codebook is counted from 1. In some arrangements, the size of the first sub-codebook is determined according to an uplink DAI in the first DCI. The size of the second sub-codebook is determined according to a DAI in a last DL DCI for a DL transmission.The DAI in a DCI DL for the transmission of the DL corresponding to the second codebook sub-book is counted from 1.

[0104] As shown in FIG. 8, there are two DL DCIs 812 and 816 that do not start before or after UL DCI 810 and PDSCHs 814 and 818 scheduled by DL DCIs 812 and 816, respectively. Feedback for PDSCHs 814 and 818 scheduled by DL DCIs 812 and 816, respectively, is indicated as being provided in slot 810 of PUSCH 822 scheduled by UL DCI 810. UE 104 generates the second codebook including feedback information for these DL transmissions (e.g., PDSCHs 814 and 818) and will be transmitted on PUSCH 822. The size of the first sub-codebook is determined as 4*n+2 according to the UL DAI value (e.g., 2) in UL DCI 810. The size of the second sub-codebook is determined as 4*m+2 according to the value Petition 870250106365, dated 11 / 19 / 2025, pp. 49 / 62 42 / 46 of the total DAI (e.g., total DAI 2) in the last DL DCI 816. Since DAI is counted cyclically in units of 4, the UL DAI equals 2, which represents a quantity of bits that need to be feedback is 4*n+2 or 4*m+2, and a value of n or m is determined by a quantity of DL transmissions received by UE 104. Then, the codebook size is determined as 4*n+2+4*m+2=4*(n+m)+4.

[0105] In some arrangements, the type 2 codebook to be transmitted in a scheduled PUSCH by a UL DCI may be divided into two sub-codebooks, the first sub-codebook and the second sub-codebook, which correspond, respectively, to the feedback information for DL ​​transmissions initiated before or not after the UL DCI and to the feedback information for DL ​​transmissions initiated not before or after the UL DCI. The size of the first sub-codebook is determined according to the total DAI in the first-last DL DCI, which is the last DL DCI among the DL DCIs preceding or not following the UL DCI. The size of the second sub-codebook is determined according to the total DAI in the penultimate DL DCI that is not before or after the UL DCI. In some examples, at least one of the count DAI and the total DAI in the DL DCI corresponding to the second sub-codebook, starting at 1.

[0106] Consequently, the arrangements described herein allow feedback information for DL ​​transmissions received by the UE after the UL DCI to be provided in the PUSCH scheduled by the UL DCI. The restriction on scheduling DL after the UL DCI is lifted, and system transmission efficiency can be improved.
