15. An apparatus for wireless communication, comprising:
memory; and
one or more processors coupled to the memory, the memory comprising instructions that when executed by the one or more processors, individually or collectively, cause the apparatus to:
determine whether to activate prescheduled resources on one or more candidate component carriers (CCs) to be used for communication of one or more reference signals with a user-equipment (UE) based on a signal quality of a serving CC, wherein the determining of whether to activate the prescheduled resources on the one or more candidate CCs based on the signal quality of the serving CC comprises determining whether to activate the prescheduled resources on the one or more candidate CCs based on whether an acknowledgement corresponding to a previous data transmission on the serving CC has been received;
receive a negative acknowledgment (NACK) corresponding to the previous data transmission;
communicate the one or more reference signals with the UE via the prescheduled resources on the one or more candidate CCs, wherein the prescheduled resources are activated in response to the reception of the NACK;
select one of the one or more candidate CCs based on the one or more reference signals; and
transmit data on the one of the one or more candidate CCs.
