Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive physical-layer control information indicating to activate or deactivate a secondary cell; and activate or deactivate the secondary cell within a time period in accordance with the physical-layer control information, wherein the time period is based at least in part on a set of factors and based at least in part on the secondary cell being activated or deactivated by the physical-layer control information. Numerous other aspects are provided.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving physical-layer control information indicating to activate or deactivate a secondary cell;
- and
- activating or deactivating the secondary cell within a time period in accordance with the physical-layer control information,
- wherein the time period is based at least in part on a set of factors and based at least in part on the secondary cell being activated or deactivated by the physical-layer control information,
- wherein the set of factors includes a status associated with the secondary cell being a known status, wherein the secondary cell is associated with the known status based at least in part on the UE having reported a measurement for a synchronization signal block (SSB) for the secondary cell within a time window, the SSB for which the measurement was reported remaining detectable within the time window, and an SSB serving as a quasi-colocation source for the measurement being detectable in the time period.

A method of wireless communication performed by a network entity, comprising:
- transmitting, to a user equipment (UE), physical-layer control information indicating to activate or deactivate a secondary cell;
- and
- receiving a communication associated with activating or deactivating the secondary cell within a time period in accordance with the physical-layer control information,
- wherein the time period is based at least in part on a set of factors and based at least in part on the secondary cell being activated or deactivated by the physical-layer control information,
- wherein the set of factors includes a status associated with the secondary cell being a known status, wherein the secondary cell is associated with the known status based at least in part on the UE having reported a measurement for a synchronization signal block (SSB) for the secondary cell within a time window, the SSB for which the measurement was reported remaining detectable within the time window, and an SSB serving as a quasi-colocation source for the measurement being detectable in the time period.
2 more elements
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- receive physical-layer control information indicating to activate or deactivate a secondary cell;
- and
- activate or deactivate the secondary cell within a time period in accordance with the physical-layer control information,
- wherein the time period is based at least in part on a set of factors and based at least in part on the secondary cell being activated or deactivated by the physical-layer control information,
- wherein the set of factors includes a status associated with the secondary cell being a known status, wherein the secondary cell is associated with the known status based at least in part on the UE having reported a measurement for a synchronization signal block (SSB) for the secondary cell within a time window, the SSB for which the measurement was reported remaining detectable within the time window, and an SSB serving as a quasi-colocation source for the measurement being detectable in the time period.
