Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a multi-subscriber identity module (SIM) user equipment (UE) may communicate, using a first SIM, on a plurality of component carriers. The multi-SIM UE may select a first subset of component carriers from the plurality of component carriers based at least in part on a component carrier prioritization. The multi-SIM UE may identify an amount of memory available to a second SIM. The multi-SIM UE may tune away, based at least in part on the amount of memory available to the second SIM, from a second subset of component carriers The first subset of component carriers may be different from the second subset of component carriers. Numerous other aspects are described.

An indicator in a master AP from among a plurality of APs obtains communication quality of communication with an AP which is a communication partner. In the case where the obtained communication quality is less than a threshold, the indicator causes the plurality of APs including the master AP to perform cooperative operation to transmit data. In the case where the obtained communication quality is not less than the threshold, the indicator causes the plurality of APs including the master AP to stop the cooperative operation.
