Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit communications on a primary component carrier and a secondary component carrier (SCC). The UE may refrain from transmission on the SCC based at least in part on an error rate for transmission on the SCC and an amount of transmission power headroom for the UE. Numerous other aspects are provided.
Claims30
A user equipment (UE) for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- transmit communications on a primary component carrier (PCC) and a secondary component carrier (SCC);
- and
- refrain from transmission on the SCC based at least in part on the UE determining to drop the SCC, wherein the UE determines to drop the SCC using:
- a determination by the UE that an error rate of the transmitted communications on the SCC satisfies an error threshold, and
- a determination by the UE that an amount of transmission power headroom available to the UE for transmitting on the SCC does not satisfy a power threshold.
A base station for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- schedule uplink communications for a user equipment (UE) on a primary component carrier (PCC) and a secondary component carrier (SCC);
- and
- adjust scheduling of uplink communications for the UE on the SCC based at least in part on the UE dropping the SCC, wherein the UE drops the SCC using:
- a determination that an error rate of the uplink communications on the SCC satisfies an error threshold, and
- a determination that an amount of transmission power headroom available to the UE for transmitting on the SCC does not satisfy a power threshold.
A method of wireless communication performed by a user equipment (UE), comprising:
- transmitting communications on a primary component carrier (PCC) and a secondary component carrier (SCC);
- and
- refraining from transmission on the SCC based at least in part on the UE determining to drop the SCC, wherein the UE determines to drop the SCC using:
- a determination by the UE that an error rate of the transmitted communications on the SCC satisfies an error threshold, and
- a determination by the UE that an amount of transmission power headroom available to the UE for transmitting on the SCC does not satisfy a power threshold.
A method of wireless communication performed by a base station, comprising:
- scheduling uplink communications for a user equipment (UE) on a primary component carrier (PCC) and a secondary component carrier (SCC);
- and
- adjusting scheduling of uplink communications for the UE on the SCC based at least in part on the UE dropping the SCC, wherein the UE drops the SCC using:
- a determination that an error rate of the uplink communications on the SCC satisfies an error threshold, and
- a determination that an amount of transmission power headroom available to the UE for transmitting on the SCC does not satisfy a power threshold.
