Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a physical downlink control channel (PDCCH) scheduling a physical downlink shared channel (PDSCH). The UE may transmit a physical uplink control channel (PUCCH) based on a PUCCH repetition factor, wherein the PUCCH repetition factor is indicated by a location of a control channel element (CCE) of the PDCCH, a PUCCH resource indicator (PRI) bitfield of the PDCCH, and at least one of: one or more parameters of the PDCCH, or one or more parameters of the PDSCH. Numerous other aspects are provided.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a request to transmit one or more canceled hybrid automatic repeat request (HARQ) codebooks, the one or more canceled HARQ codebooks having been scheduled for transmission within a time window preceding receiving the request. The UE may transmit the one or more canceled HARQ codebooks via one or more resources associated with the request. Numerous other aspects are described.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a semi-persistent scheduling (SPS) downlink communication. The UE may detect a collision between a configured uplink resource associated with a hybrid automatic repeat request acknowledgement (HARQ-ACK) for the SPS downlink communication and a candidate synchronization signal block (SSB) position. The UE may transmit the HARQ-ACK for the SPS downlink communication in the configured uplink resource or in a deferred uplink resource in connection with detecting the collision. Numerous other aspects are described.

This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for semi-persistent scheduling (SPS) and hybrid automatic repeat request (HARQ) feedback skipping for user equipment (UE)-initiated transmissions. A UE configured for extended reality (XR) operations and an SPS configuration including a plurality of SPS occasions, each SPS occasion configured with at least one downlink resource and at least one uplink resource, collects pose information related to at least one SPS occasion. The UE determines, based on the pose information, to skip at least one SPS occasion. The UE sends an indication of the determination to skip the at least one SPS occasion to a base station. The indication is transmitted in a preconfigured uplink resource or may be piggyback an uplink transmission. The base station may reallocate the resources configured for the at least one SPS occasion based on receiving the indication.

A communication device for handling a hybrid automatic repeat request (HARQ) transmission, comprises at least one storage device; and at least one processing circuit, coupled to the at least one storage device, wherein the at least one storage device stores instructions, and the at least one processing circuit is configured to execute the instructions of: receiving a configuration from a network, wherein the configuration comprises a time domain resource allocation (TDRA) table and a set of a plurality of timing values; and receiving a downlink (DL) control information (DCI) from the network, wherein the DCI indicates a row of the TDRA table for at least one physical DL shared channel (PDSCH) reception and indicates a timing value of the set of the plurality of timing values for the HARQ transmission corresponding to the at least one PDSCH reception.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a random access response associated with a random access channel (RACH) procedure. The UE may transmit, based at least in part on receiving the random access response, data indicating a request for coverage enhancement associated with an acknowledgment associated with the RACH procedure. Numerous other aspects are described.

Methods, systems, and devices for wireless communication are described. A wireless communications system may support one or more communication devices (e.g., user equipment (UE)) operating according to an aperiodic (e.g., and dynamic) discontinuous reception (DRX) mode. For example, a UE may communicate with a device in the wireless communications system (e.g., a base station, another UE) according to a periodic DRX mode. In response to a transition indication, the UE may dynamically transition to the aperiodic DRX mode and may operate according to the aperiodic DRX mode for a duration. To operate according to the aperiodic DRX mode, the UE may be configured to disable a first set of communication operations for the duration, perform a second set of communication operations during the duration, or a combination thereof (e.g., across component carriers of a carrier group, across component carriers of a DRX group).

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a user equipment (UE) may receive a configuration for an aggregate component carrier. The aggregate component carrier may include a combination of multiple component carriers. The apparatus may perform a half-duplex communication utilizing the aggregate component carrier. Numerous other aspects are described.

A method and a user equipment (UE) for performing a Configured Grant-based Small Data Transmission (CG-SDT) is provided. The method includes performing an initial transmission of the CG-SDT via a first configured Uplink (UL) grant associated with a Hybrid Automatic Repeat Request (HARQ) process; determining whether a feedback from the BS has been received for the first configured UL grant associated with the HARQ process; and performing a retransmission for the initial transmission of the CG-SDT via a second configured UL grant if the feedback has not been received.

A method and a user equipment (UE) for handling a survival time state are provided. The method includes: receiving a Packet Data Convergence Protocol (PDCP) configuration for indicating that a Data Radio Bearer (DRB) associated with a PDCP entity supports a survival time state functionality, the PDCP entity being associated with at least two Radio Link Control (RLC) entities; receiving an Uplink (UL) grant for retransmission of a Medium Access Control (MAC) Protocol Data Unit (PDU), the MAC PDU including data from the DRB; entering the survival time state for the DRB upon receiving the UL grant; and activating a PDCP duplication for the PDCP entity during the survival time state.
