Abstract: Certain aspects of the present disclosure provide techniques for configuring sidelink slots without symbols for automatic gain control. One aspect provides a method for wireless communication by a user equipment, including receiving a first cyclic prefix of a first symbol within a slot at the user equipment. The method further includes configuring a first automatic gain control setting based on a received power in the first cyclic prefix of the first symbol, and receiving a data portion of the first symbol using the first automatic gain control setting.

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.

Abstract: A user equipment (UE) may obtain high-priority data (e.g., low latency data) to be transmitted to a base station. In some scenarios, the base station may be transmitting downlink transmissions to the UE or to a different UE, or may be receiving uplink transmissions from the UE or from the different UE. The described aspects enable the UE to timely transmit the high-priority data in these scenarios. In one example, the described aspects enable the UE to transmit, to the base station, while the base station performs one or more scheduled downlink transmissions to the UE or to the different UE, at least one of the high-priority data via a first uplink beam from a set of uplink beams for unscheduled uplink transmissions or an unscheduled data indication indicating that the high-priority data is to be transmitted without an uplink grant.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information that indicates a resource allocation for a downlink transmission and an uplink resource for transmission of a hybrid automatic repeat request (HARQ) codebook. The UE may transmit, to the base station, uplink control information (UCI) that includes an indication of whether transmission of the HARQ codebook is cancelled. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support channel state information (CSI) operations, such as CSI reporting. A UE may identify a change in CSI pertaining to communications with a base station or any other change in communications with a base station. The UE may transmit, to the base station and based on the change in CSI, a CSI scheduling request, which may include an indication to activate or grant resources for a CSI report transmission from the UE to the base station. The UE may receive, from the base station, a CSI report trigger based on the CSI scheduling request, and transmit, in response to receipt of the CSI report trigger, a CSI report over a physical layer uplink channel (e.g., a physical uplink shared channel (PUSCH)).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message scheduling a burst of downlink messages. The control message may indicate first and second pluralities of transmission configuration indicators associated with first and second downlink shared channels, respectively. The UE may monitor for a first and second downlink messages in the first downlink shared channel and the second downlink shared channel, using first and second transmission configuration indicators, respectively. Additionally, or alternatively, the UE may receive a control message scheduling a burst of uplink messages. The single control message may indicate to apply a first precoding matrix for transmission of the uplink messages. The UE may precode, using a second precoding matrix, an uplink message to generate a precoded first uplink message. The UE may transmit the precoded uplink message in a first uplink shared channel.

Abstract: This disclosure provides systems, methods and apparatus for applying a unified transmission configuration indicator (TCI) state to a downlink reference signal in accordance with a rule or procedure that is mutually known between a user equipment (UE) and one or more components of a base station (BS). In one aspect, the UE and one or more components of the BS may support a unified TCI state associated with a transmission over a downlink data channel and a transmission over a downlink control channel. The UE and one or more components of the BS may apply the unified TCI state to the downlink reference signal (which may be associated with beam selection for the downlink reference signal) in accordance with a satisfaction of a condition associated with the downlink reference signal. Such a condition may be associated with one or more parameters or configurations associated with the downlink reference signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, in a current cycle, information related to downlink transmission duplication on multiple component carriers, wherein each of the multiple component carriers is associated with a semi-persistent scheduling (SPS) configuration. The UE may monitor a subset of the multiple component carriers for a scheduled SPS occasion in one or more of the current cycle or a next cycle based at least in part on the information related to the downlink transmission duplication on the multiple component carriers in the current cycle. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for applying uplink transmission configuration indicator (TCI) states with downlink reference signals to codebook based physical uplink shared channel (PUSCH) transmissions. An example method generally includes receiving, from a network entity, signaling of an uplink transmission configuration indicator (TCI) state with a target codebook based uplink transmission signal, determining if the TCI state has a source downlink reference signal (RS) and deciding how to process the codebook based uplink transmission based on the determination.
