Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a first serving cell, Layer 3 (L3) control signaling indicative of multiple sets of parameters for primary serving cell and secondary serving cell operation. The UE may receive, from the first serving cell, via Layer 2 (L2) control signaling indicating an activation of a second serving cell at the UE and an indication that specifies that the second serving cell is to be activated as a primary serving cell. The UE may then communicate with the second serving cell as the primary serving cell based on receiving the second signaling and in accordance with a set of parameters from the multiple sets of parameters indicated by the L3 control signaling.

Techniques for layer 2 signaling for layer 1 and layer 2 mobility

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first serving cell via Layer 3 control signaling, a configuration indicating a plurality of transmission reception points (TRPs) and one or more parameters enabling activation or deactivation of TRPs in the plurality of TRPs. The UE may receive, from the first serving cell via Layer 2 control signaling, explicit multi-TRP information that indicates an activation of a second serving cell and a TRP associated with the second serving cell, wherein the explicit multi-TRP information indicates that the second serving cell is to be activated as a primary cell and the TRP is to be activated as a primary TRP. The UE may communicate with the primary cell and the primary TRP. Numerous other aspects are described.

Signaling for multiple transmission reception point activation and deactivation

Certain aspects of the present disclosure provide techniques wireless communication by a user equipment (UE), comprising receiving an uplink (UL) grant from a network entity, wherein the UL grant schedules the UE to transmit an UL channel transmission associated with a plurality of logical channels (LCs), and the UL grant indicates a modulation and coding scheme (MCS) for transmitting the UL channel transmission associated with the plurality of LCs, receiving a plurality of MCS offsets, and transmitting the UL channel transmission associated with one or more LCs of the plurality of LCs based on the MCS indicated in the UL grant and the plurality of MCS offsets.
