Abstract: Aspects for enhanced logical channel prioritization mapping procedures and restrictions are disclosed. In one aspect, a method of wireless communication includes transmitting, by a network entity, a logical channel prioritization (LCP) restriction configuration for a logical channel indicating a set of Sounding Reference Signal (SRS) configurations associated with the logical channel; determining, by the network entity, data of the logical channel of a particular UE is to be scheduled; transmitting, by the network entity, an uplink grant indicating an uplink grant instance for the particular UE, wherein the uplink grant instance indicates an SRS configuration of the set of SRS configurations; and receiving, by the network entity, a transmission corresponding to the uplink grant instance and including the data of the logical channel. Additional aspects are described.

Abstract: Methods, systems, and devices for signaling for transmission configuration indication (TCI) state activation for multiple transmission reception points are described. A user equipment (UE) may receive at least one control message indicating a first set of beam configurations associated with a first downlink shared channel from a first transmission reception point (TRP) and a second set of beam configurations associated with a second downlink shared channel from a second TRP. The UE may receive downlink control information (DCI) from the first and second TRPs indicating a first beam configuration of the first set of beam configurations and a second beam configuration of the second set of beam configurations, respectively. The UE may subsequently decode a first downlink transmission from the first downlink shared channel according to the first beam configuration and a second downlink transmission from the second downlink shared channel according to the second beam configuration.

Abstract: Methods, systems, and devices for wireless communication are described. A UE may receive control signaling scheduling transmission of a plurality of repetitions of an uplink message and indicating a time gap threshold between at least one pair of adjacent repetitions. The UE may transmit a first repetition of the uplink message based at least in part on the control signaling. The UE may transmit, based on the control signaling, a second repetition of the uplink message separated in time from transmission of the first repetition of the uplink message by a time gap satisfying the time gap threshold.

Abstract: Apparatus, methods, and computer-readable media for sidelink multiple transmission reception points (TRPs) relaying are disclosed herein. An example method for wireless communication at a base station includes transmitting communication for a target user equipment (UE) to multiple TRPs for relaying the communication to the target UE over a sidelink. The method may further include configuring, for one or more of the target UE or at least one of the multiple TRPs, a first transmission configuration indicator (TCI) state for a physical sidelink control channel (PSCCH) between the UE and the at least one of the multiple TRPs.

Abstract: The apparatus receives a PUCCH resource configuration associated with a PUCCH resource. The PUCCH resource configuration indicates at least one of a PUCCH resource repetition configuration or a PUCCH resource inter-slot frequency hopping configuration for the PUCCH resource that is independent of PUCCH formats. In addition, the apparatus transmits a PUCCH in the PUCCH resource based on the at least one of the PUCCH resource repetition configuration or the PUCCH resource inter-slot frequency hopping configuration configured in the PUCCH resource configuration. The received PUCCH resource configuration may override a PUCCH format configuration. The apparatus may receive a DCI indicating the PUCCH resource and/or a MAC-CE associated with the PUCCH resource configuration, and may transmit the PUCCH based on the received DCI/MAC-CE.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may communicate with a set of transceiver nodes (e.g., transmission reception points (TRPs)) in a first transceiver node operation mode (e.g., a multi-TRP mode). A first transceiver node of the set of transceiver nodes may receive, from a second of the set of transceiver nodes, an indication to switch between rate matching states. The first transceiver node may switch from a first rate matching state to a second rate matching state and may transmit a downlink shared channel based on a resource configuration associated with the second rate matching state. The UE may receive the shared channel based on an antenna port configuration determined by the UE based on the first transceiver node operation and rate matching information. The rate matching information may be provided by the first transceiver node.

Abstract: Methods, systems, and devices for wireless communications are described that support group-based acknowledgment feedback techniques. Two or more different groups of downlink transmissions may each have an associated group-based acknowledgment feedback, and a base station may transmit downlink control information to a UE that indicates one or more parameters that are used to determine which downlink transmissions are to be reported in the group-based feedback. Based on the parameters in the downlink control information, the UE may determine the feedback to be reported, and a timing for when to transmit the feedback to the base station.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) receives physical downlink control channels from transmission and reception points (TRPs). The physical downlink control channels may be jointly decoded to facilitate joint demodulation of physical shared channels. The UE receives a first downlink control information (DCI) over a first downlink control channel associated with a first TRP and a second DCI over a second downlink control channel associated with a second TRP. The first downlink control channel overlaps in time with the second downlink control channel. The first DCI schedules a first downlink shared channel associated with the first TRP and the second DCI schedules a second downlink shared channel associated with the second TRP. The UE receives the first downlink shared channel and the second downlink shared channel that overlap in time. The UE performs joint demodulation of the first and second downlink shared channels.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a synchronization signal block (SSB) including a physical layer cell identifier (PCI), where one or more resource elements carrying the SSB overlap with resource elements carrying a downlink shared channel associated with another PCI. The PCIs may be for a serving cell or another cell, such as a non-serving cell. The UE may also receive one or more demodulation reference signals (DMRSs) in the one or more resource elements in the downlink shared channel. The UE may determine whether overlap is permitted between the resource elements by comparing the PCIs of the SSB and the downlink shared channel. In some examples, once the UE determines whether resource element overlap is permitted, the UE may process the DMRSs.
