Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, downlink control information that indicates a wakeup signal for a broadcast or multicast (broadcast/multicast) session in a session-specific field of the downlink control information. The user equipment may selectively perform, for the broadcast/multicast session, a wakeup operation for a discontinuous reception cycle based at least in part on the wakeup signal. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for port selection for channel state feedback with analog feedforward. A method that may be performed by a user equipment (UE) includes selecting one or more channel state information reference signals (CSI-RS) ports, of a plurality of CSI-RS ports, for the UE to report CSI. The port selection includes selecting any of the plurality of CSI-RS ports for selecting CSI-RS based on a grouping of the plurality of CSI-RS ports. The UE determines a precoding matrix indicator (PMI) formed by a linear combination of the one or more selected CSI-RS ports. The UE computes at least wideband linear combination coefficients for the selected CSI-RS ports. The UE provides the selected one or more CSI-RS ports and the computed wideband linear combination coefficients to a base station (BS) in a CSI report.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify a slot format configuration, such as a time division duplex (TDD) slot format configuration, and one or more downlink repetition configurations corresponding to a number of downlink repetitions for a user equipment (UE). The base station may transmit the configurations to the UE. The UE may determine that the number of downlink repetitions and the configured slot format satisfy, or fail to satisfy, a validation rule for monitoring the number of downlink repetitions. The UE may monitor, or refrain from monitoring, the number of repetitions based on whether the validation rule is satisfied.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, downlink control information (DCI) scheduling an uplink multiple input multiple output (MIMO) communication. The UE may transmit, and the base station may receive, the uplink MIMO communication using a default sounding reference signal (SRS) resource configuration based at least in part on the UE receiving the DCI prior to a medium access control (MAC) control element (MAC-CE) selecting a subset of uplink transmission configuration indication (TCI) states included in an uplink TCI state pool configured for the UE. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a control resource set (CORESET) that indicates a precoder granularity unit over which a same precoding is used for resources of the CORESET. The precoder granularity unit may be greater than a resource element group bundle of the CORESET and less than contiguous resource blocks of the CORESET. The UE may monitor for one or more physical downlink control channel candidates according to the configuration. Numerous other aspects are provided.

Abstract: In an aspect, a BS is configured as a serving cell of a UE. The BS transmits data to the UE in accordance with a frequency hopping scheme over a first set of T-F resources of a first BWP and a second set of T-F resources of a second BWP. The BS (or another BS) further transmits, to the UE over a third BWP that is different than the second BWP, a PDCCH including a PI field with a PI associated with the transmitted data over the second set of T-F resources of the second BWP. The UE receives the data and the PDCCH. The UE processes the received data over (at least) the second set of T-F resources based on the PI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability report to a base station indicating a triggering offset. The base station may configure the UE with one or more channel state information (CSI) measurement resources and send downlink control information (DCI) that triggers an aperiodic CSI report for some of the CSI measurement resources. The UE may report CSI by measuring the CSI resources after the triggering offset. In some cases, CSI reporting related to the different codebook types (e. g., Type I, Type II) may be modified, where after identifying a type of codebook and determining which type of codebook to process (e. g., based on a number of CSI processing units), the UE may identify a priority associated with different CSI reports. The UE may be configured with various parameters that relax or modify the processing of Type II CSI reports.

Abstract: Various aspects of the present disclosure generally relate to multi-slot transmission time interval based channel state information (CSI) and uplink shared channel (UL-SCH) multiplexing. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) message and determine, based at least in part on the DCI message, a schedule for multiplexing UL-SCH data and one or more components of uplink control information (UCI) in a plurality of slots on a physical uplink shared channel (PUSCH). The components may include a CSI report for a plurality of transmission reception points. The UE may multiplex the UL-SCH data and the one or more components into the plurality of slots based at least in part on the schedule. Numerous other aspects are provided.
