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 identifies an association between a first cell of a first radio access technology (RAT) and a second cell of a second RAT. The UE may perform a measurement for the first cell. The UE may determine that the measurement for the first cell satisfies a threshold value. The UE may perform an interference canceling operation for a reference signal of the second cell, or a de-weighting operation for one or more resource elements in which the reference signal interferes, based at least in part on the determination that the measurement for the first cell satisfies the threshold value and the association between the first cell and the second cell. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described, in which a communication device (e.g., a user equipment (UE), a network entity) may perform carrier aggregation, and cross-carrier scheduling provides that a first carrier may provide scheduling information for one or more other carriers, in which the one or more other carriers may have different discontinuous reception (DRX) configurations than the first carrier. One or more DRX-related timers of different DRX groups may be started or restarted based on a control information reception on the first carrier, or on a different carrier of a different DRX group. Additionally, or alternatively, control information transmissions on the first carrier may be provided based on one or more DRX-related timers that are associated with the first carrier, or that are associated with a carrier of another DRX group than the DRX group of the first carrier, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support dynamic uplink control channel grouping. For example, a user equipment (UE) may receive control signaling indicating multiple uplink control channel groups for the UE, where each uplink control channel group of the multiple uplink control channel groups is associated with a different set of uplink control channel resources. Additionally, the UE may select an uplink control channel group for a component carrier (CC) associated with the UE, where the uplink control channel group is selected in accordance with a detected trigger at the UE. Further, the UE may transmit uplink control information for the CC in accordance with the selected uplink control channel group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information that indicates an uplink transmit switching configuration for performing uplink transmit switching between a first component carrier and a second component carrier and a sounding reference signal (SRS) carrier switching configuration for performing SRS carrier switching between the second component carrier and a third component carrier, wherein the configuration information is associated with a maximum number of allowable switches over an amount of time. The UE may transmit, based at least in part on the configuration information, one or more signals associated with performing at least one of uplink transmit switching or SRS carrier switching. Numerous other aspects are described.
