A UE may determine a target slot for HARQ deferral for transmission of first HARQ-ACK information, based on transmission of the first HARQ-ACK information overlapping with a downlink symbol in a first slot, transmit a second HARQ-ACK codebook including a first HARQ-ACK codebook in a second slot for retransmission of the first HARQ-ACK codebook, based on DCI triggering retransmission of the first HARQ-ACK codebook scheduled to be transmitted in the first slot, and transmit uplink control information in the target slot. The uplink control information does not include the first HARQ-ACK information, based on the second HARQ-ACK codebook including the first HARQ-ACK information.

UCI MULTIPLEXING PROCEDURE FOR MULTIPLE OVERLAPPING CHANNELS AT DIFFERENT PHYSICAL LAYER PRIORITIES

Performing UCI multiplexing includes generating PUCCH resources Z at an L1 HP procedure and an L1 LP procedure. The L1 HP procedure and the L1 LP procedure results in a plurality of HP PUCCHs and LP PUCCHs, respectively. A modified procedure for Set Q to resources Z is performed with the plurality of HP PUCCHs and LP PUCCHs as inputs. The plurality of HP PUCCHs according to starting symbols is scanned to identify an earliest starting HP PUCCH. A PUCCH from the plurality of LP PUCCHs or HP PUCCHS that overlaps with the earliest starting HP PUCCH is collected. Inter-L1 priority multiplexing is performed on the earliest starting HP PUCCH and the collected PUCCH, which may result in a new HP PUCCH. The new HP PUCCH is inserted into the Set Q. The modified procedure is repeated until there is no overlap among the HP PUCCHs and the LP PUCCHs.

Concurrent physical sidelink feedback channel transmission

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify multiple candidate sets of physical sidelink feedback channel (PSFCH) transmissions that include hybrid automatic repeat request (HARQ) feedback for sidelink communications received from one or more peer UEs. The UE may select, from one or more of the multiple candidate sets that satisfy a PSFCH transmit power constraint, at least one candidate set that has a highest value for a utility parameter among utility parameters associated with each of the one or more candidate sets that satisfy a PSFCH transmit power constraint. The UE may transmit, on a PSFCH, the plurality of PSFCH transmissions included in the at least one candidate set in a HARQ feedback occasion. Numerous other aspects are provided.

Transmission of uplink control information (UCI) based on one or more codebooks

Wireless communication devices, systems, and methods related to communicating UCI are provided. For example, a method of wireless communication may include receiving, by a user equipment (UE) from a base station (BS), scheduling information for transmitting a hybrid automatic repeat request acknowledgement (HARQ-ACK) and uplink control information (UCI) during a time period. The UCI may include channel state information (CSI) or a scheduling request (SR). The method may include determining, by the UE, that the UCI and a HARQ-ACK codebook have a common priority, the HARQ-ACK being based on the HARQ-ACK codebook. The method may include transmitting, by the UE to the BS, the HARQ-ACK and the UCI during the time period based on the scheduling information, the transmitted UCI using resources determined based on a duration associated with the HARQ-ACK codebook, and the duration being based on the UCI and the HARQ-ACK codebook having the common priority.

Method and apparatus for group scheduling for PDCCH overhead reduction

Methods and apparatuses for group scheduling for physical downlink control channel (PDCCH) overhead reduction. A method of operating a UE includes receiving first configuration information for reception of first PDCCHs. A PDCCH from the first PDCCHs provides a first downlink control information (DCI) format that includes a first number of information bits. The method further includes receiving second configuration information for a location of a second number of information bits, smaller than the first number of information bits, in the first DCI format; receiving at least one of the first PDCCHs; and determining, from the second number of information bits, values of one or more fields associated with reception of a first physical downlink shared channel (PDSCH) or with transmission of a first physical uplink shared channel (PUSCH).

Radio communication apparatus and radio communication method

Provided is a radio communication device which can make Acknowledgement (ACK) reception quality and Negative Acknowledgement (NACK) reception quality to be equal to each other. The device includes: a scrambling unit (214) which multiplies a response signal after modulated, by a scrambling code “1” or “e.sup.−j(π/2)”, so as to rotate a constellation for each of response signals on a cyclic shift axis; a spread unit (215) which performs a primary spread of the response signal by using a Zero Auto Correlation (ZAC) sequence set by a control unit (209); and a spread unit (218) which performs a secondary spread of the response signal after subjected to the primary spread, by using a block-wise spread code sequence set by the control unit (209).

Scheduling and hybrid automatic repeat request operation and codebook design for new radio carrier aggregation

Techniques are described relating to hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback using a HARQ-ACK aggregation window. A User Equipment (UE) may receive control information (e.g., downlink control information (DCI) or radio resource control (RRC) signaling) from a base station including HARQ-ACK codebook information. The HARQ-ACK codebook information may include information on a size of a HARQ-ACK aggregation window. The UE may decode physical downlink shared channel (PDSCH) transmissions and encode corresponding HARQ-ACK feedback using the HARQ-ACK aggregation window based on the control signaling.

Method and apparatus for transmitting response information on feedback resources

Provided are a method and apparatus for transmitting information, and a storage medium and a terminal. The method includes: determining, on an uplink feedback resource unit within a first downlink resource range currently occupied during downlink transmission, whether first response information corresponding to the first downlink resource range is successfully transmitted to a base station, wherein the uplink feedback resource unit includes a resource unit for transmitting the first response information to the base station; when the first response information is transmitted unsuccessfully, determining a target feedback resource unit within at least one second downlink resource range subsequently occupied during the downlink transmission; and retransmitting, on the target feedback resource unit, the first response information to the base station.
