Low overhead component carrier selection for multi-component carrier communication

A method for wireless communications by a network device, comprising:

• transmitting control signaling configuring a user equipment (UE) with a plurality of component carriers for communicating with the network device and a semi-persistent resource allocation of a resource;
• transmitting an availability indicator that indicates availability of the resource of the semi-persistent resource allocation on each component carrier of the plurality of component carriers, wherein the availability indicator indicates a number of time intervals within a time window for which the availability indicator is valid;
• and
• communicating a data transmission via at least a subset of the plurality of component carriers based at least in part on the availability indicator.

An apparatus for wireless communications by a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive control signaling configuring the UE with a plurality of component carriers for communicating with a network device and a semi-persistent resource allocation of a resource for each component carrier of the plurality of component carriers;
• identify an availability indicator that indicates availability of the resource of the semi-persistent resource allocation on each component carrier of the plurality of component carriers, wherein the availability indicator indicates a number of time intervals within a time window for which the availability indicator is valid;
• and
• communicate a data transmission via at least a subset of the plurality of component carriers based at least in part on the availability indicator.
