Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a channel state information reference signal for a downlink cell associated with a first physical uplink control channel (PUCCH) group. The UE may report measurement information associated with channel state information reference signal using an uplink cell of a second PUCCH group associated with the first PUCCH group. Numerous other aspects are described.

Abstract: Mechanisms for rate matching a downlink communication channel in a multi-radio access technology (RAT) communication scenario are described. In one aspect, a method for wireless communication performed by a base station (BS) includes rate matching, based on a rate matching pattern indicating a plurality of reserved resource elements, a downlink (DL) communication channel. The method further includes transmitting, to a user equipment (UE) on one or more antenna ports, a DL communication in the rate matched DL communication channel. The method further includes transmitting, on the one or more antenna ports, one or more signals in the plurality of reserved resource elements. The one or more signals transmitted in the plurality of reserved resource elements may allow UEs associated with other RATs to estimate the rate matched DL communication channel.

Abstract: A UE may receive, from a serving cell, an activation indication for an SCell, receiving a first reference signal from the SCell, the first reference signal including at least one temporary reference signal, identify whether a second reference signal is received after processing the activation indication and before an expiration of an SCell activation time, and activate, upon identifying that the second reference signal is received, the SCell based on one or more reference signals including at least one of the first reference signal or the second reference signal. The UE may activate the SCell no later than in slot n+K, and K may be determined based on at least in part the SCell activation time.

Abstract: Methods, systems, and devices for wireless communication are described that provide for aligning a starting time of a cell-based discontinuous transmission (DTX) and/or discontinuous reception (DRX) mode between a network entity and one or more user equipment (UE) within the serving cell associated with the network entity. The aligning may be accomplished via coordinated signaling. For example, the network may configure a periodic interval for transmitting information related to a discontinuous operation mode in group common downlink control information (GC DCI) messages. In some additional examples, the periodic interval may allow for beam sweeping of the GC DCI messages and efficient cell-based activation or deactivation of the discontinuous operation mode.

Abstract: Certain aspects of the present disclosure provide techniques for improving time division duplexing (TDD) downlink-uplink configuration for new radio (NR) operation with large timing advancements (TAs). An example method by a user equipment (UE) includes transmitting, to a network entity, an indication of a timing advance (TA) value; receiving, from the network entity, information indicating a set of downlink slots of a time division duplexing (TDD) pattern that is dynamically restricted from being scheduled for the UE, wherein the set of downlink slots is based on the TA value; and receiving, from the network entity, downlink transmissions in downlink slots of the TDD pattern except in downlink slots included in the set of downlink slots.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a UE-specific configured grant (CG) small data transmission (SDT) configuration with parameters specific to CG-SDT in a non-terrestrial network (NTN). The UE may receive system information associated with validation of the parameters for CG-SDT on the NTN. The UE may transmit an SDT to a network entity of the NTN using one or more of the parameters. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication that the UE is to perform radio resource management (RRM) measurements at a first periodicity. The UE may identify an RRM measurement relaxation grouping to which the UE belongs based on at least one of a mobility of the UE or a location of the UE within a cell, such as whether the UE is near a cell-edge, or whether the UE is stationary or moving in accordance with low-mobility, or a combination thereof. The UE may determine a first relaxation parameter from a plurality of relaxation parameters based on measurement relaxation criterion associated with the cell, where the plurality of relaxation parameters may be associated with the RRM measurement relaxation grouping. The UE may perform the RRM measurements at a second periodicity that is based on the first relaxation parameter.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that includes trigger information for generating a measurement report for one or more candidate secondary cells after receiving an activation command that activates a secondary cell for which the UE has not reported measurements. The UE may receive the activation command. The UE may transmit the measurement report based at least in part on the activation command and the trigger information. Numerous other aspects are described.
