This disclosure provides systems, methods, apparatus, computer programs encoded on computer readable-medium to provide a user equipment (UE) to receive a reference signal from a base station, wherein the reference signal is received within a frequency-time region that overlaps with a control channel frequency-time region, generate information related to a control channel between the UE and the base station based on the reference signal, and transmitting the information to the base station.

Channel state information (CSI) feedback for physical downlink control channel (PDCCH)

Aspects are provided which allow a UE to defer HARQ-ACK reporting in PUCCH transmissions according to a configured HARQ-ACK codebook. In one aspect, the UE receives, from a base station, information triggering feedback for DL HARQ processes of the UE, the UE receives a RRC message configuring the feedback to be for less than all of the DL HARQ processes, and the UE reports the feedback based on the information and the RRC message. In another aspect, the UE reports feedback including a plurality of HARQ-ACK bits in a PUCCH, where each of the HARQ-ACK bits is associated with DL data, and at least one of the DL data is associated with a cancelled PUCCH transmission. The UE may also append to the feedback a HARQ-ACK bit associated with other DL data, where the other data is associated with another cancelled PUCCH transmission.

Additional details on reporting HARQ-ACK

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication to retransmit hybrid automatic repeat request (HARQ) feedback associated with an initial transmission on a first channel. The UE may transmit a HARQ codebook associated with the HARQ feedback on a second channel, wherein the HARQ codebook is based at least in part on at least one of: a first channel type of the first channel, or a second channel type of the second channel. Numerous other aspects are described.

Hybrid automatic repeat request codebook retransmission

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication of whether a configured grant physical uplink shared channel (CG-PUSCH) is to be transmitted, the indication being transmitted prior to a first configured symbol of the CG-PUSCH. The UE may transmit a communication in accordance with the indication. Numerous other aspects are described.

Indication of whether configured grant physical uplink shared channel is to be transmitted

To provide hybrid automatic repeat request (HARQ) feedback transmission with channel state information (CSI) report, a UE may receive triggering information associated with transmitting one or more channel state information (CSI) reports associated with one or more downlink (DL) semi-persistent scheduling (SPS) transmissions in one or more physical downlink shared channel (PDSCH) occasions. The UE may receive a first DL SPS transmission of the one or more DL SPS transmissions in a first PDSCH occasion of the one or more PDSCH occasions. The UE may transmit a first CSI report associated with the first DL SPS transmission based on receiving the triggering information.

Soft A/N report triggering for SPS PDSCH

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration corresponding to a configured grant (CG), wherein the CG is associated with a CG transmission comprising a plurality of transport blocks (TBs). The UE may receive a downlink control information (DCI) transmission comprising at least one state change indication corresponding to at least one state change associated with the CG transmission. Numerous other aspects are described.

State changes associated with a configured grant transmission of a plurality of transport blocks

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message configuring the UE to communicate coordinated transmissions with multiple transmission reception points (TRPs) using a first coordinated transmission mode of a set of different coordinated transmission modes. The UE may receive, based on the configuration message, downlink control information including at least one indicator and receive a first coordinated transmission communicated in accordance with the first coordinated transmission mode. The UE may transmit, in accordance with a feedback configuration corresponding to the at least one indicator and the first coordinated transmission mode, a feedback message for the first coordinated transmission to at least one of the multiple TRPs.

Feedback design for multi-transmission reception point transmission

Certain aspects of the present disclosure provide techniques for wireless communication by a user equipment (UE). According to certain aspects, a UE may be configured to determine that content of at least two first single-slot physical uplink control channel (PUCCHs) is to be multiplexed on to a second PUCCH, based on at least one rule, and process the second PUCCH, based on the at least one rule.

HARQ-ack feedback and intra-UE multiplexing

Wireless communications systems and methods related to wireless communications in a system are provided. A wireless communication device may compute a plurality of log-likelihood ratios (LLRs) based on a received communication signal. At least a first LLR and a second LLR of the plurality of LLRs represent the same first bit in the communication signal. The wireless communication device may combine the first LLR and the second LLR to decode the first bit and transmit a report indicating channel information. The channel information may be based at least in part on the plurality of LLRs before the combining of the first and second LLRs.

Channel information based on uncombined log likelihood ratios (LLRS)

A method of wireless communication performed by a user equipment (UE) includes receiving, from a network node, a first message configuring a group of component carriers that includes a primary component carrier and one or more secondary component carriers. The method also includes receiving, from the network node, a second message configuring a number of repetitions of a physical uplink control channel (PUCCH) transmission. The method further includes transmitting, to the network node, each repetition of the PUCCH transmission via the primary component carrier or one of the one or more secondary component carriers in accordance with the number of repetitions, each repetition being transmitted on only the primary component carrier in accordance with the number of repetitions being greater than one, and each repetition being transmitted on either the primary component carrier or the secondary component carrier in accordance with the number of repetitions being equal to one.

Physical uplink control channel (PUCCH) repetition across multiple component carriers

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration of a first hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook and a second HARQ-ACK codebook, wherein the configuration indicates that physical uplink control channel (PUCCH) carrier switching is enabled for at least one of the first HARQ-ACK codebook or the second HARQ-ACK codebook. The UE may receive an indication of a PUCCH carrier switch for the at least one of the first HARQ-ACK codebook or the second HARQ-ACK codebook. The UE may receive a downlink communication associated with the at least one of the first HARQ-ACK codebook or the second HARQ-ACK codebook. The UE may transmit HARQ feedback a target PUCCH carrier based at least in part on the indication of the PUCCH carrier switch. Numerous other aspects are described.

Physical uplink control channel carrier switch with multiple hybrid automatic repeat request acknowledgement codebooks

Techniques described provide dependent procedure operation configured for avoiding or mitigating one or more aspect of the impact on the dependent procedure of cancelling an uplink transmission. One or more attributes (e.g., a transmission indication attribute) associated with a cancelled uplink transmission may be designated for dependent procedure operation, such as for indicating whether the cancelled uplink transmission is considered either as having been transmitted or not having been transmitted. The one or more attributes associated with a cancelled uplink transmission designated for dependent procedure operation may be based upon whether the cancelling the first uplink transmission is a fast cancellation or is a slow cancellation. The designation of a transmission indication attribute for dependent procedure operation may correspond to the dependent procedure and/or its operation. Other aspects and features are also claimed and described.

Techniques for dependent procedure operation impacted by link cancellation

A method of wireless communication includes determining, by a user equipment (UE), that one or more symbols scheduled for reporting a hybrid automatic repeat request (HARQ) acknowledgement (HARQ-ACK) to a base station for a semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) transmission include at least one invalid symbol, wherein the one or more symbols are located in a first slot or sub-slot; selecting, by the UE, based on one or more parameters of the SPS PDSCH transmission, a second slot or sub-slot, subsequent to the first slot or sub-slot, for sending a delayed HARQ-ACK for the SPS PDSCH transmission; and sending, by the UE to the base station, the delayed HARQ-ACK for the SPS PDSCH transmission on the second slot or sub-slot.
