1. A method of wireless communication, comprising:
- dynamically updating a user equipment (UE) receive antenna availability for a specific radio access technology (RAT) when a receive antenna, of multiple antennas, for downlink communication for the specific RAT of the UE becomes available or unavailable to the UE after a start of a communication connection, the receive antenna capable of switching between different RATs, the updating based at least in part on a change in a number of receive antennas available for the specific RAT;
dynamically generating an indication of the updated UE antenna capability for the specific RAT after the start of the communication connection by dynamically generating a modified UE communications report to bias a base station scheduling toward at least one of a single carrier frequency mode or a carrier aggregation mode, wherein the single carrier frequency mode has more receive antennas for the downlink communication than the carrier aggregation mode;
sending the indication to the base station to reschedule the UE for communication in accordance with the updated UE receive antenna availability; and
communicating based at least in part on the rescheduling.

Abstract
A system capacity improvement is achieved by dynamically selecting a particular antenna mode of operation from the multiple radio access technology modes. In some implementations, the system capacity improvement is achieved by dynamically generating an indication of a user equipment (UE) antenna capability during a communication connection. The UE'"'"'s indication of its antenna capability is dynamic and/or is subject to change throughout the duration of the communication connection. The indication may be sent to a base station.
