1. A method for wireless communications, comprising:
- identifying a first frequency division duplex (FDD) group to communicate with the base station;
sending a request to a base station to join the first FDD group;
receiving a request from the base station to switch to a second FDD group;
switching to the second FDD group in response to the received request; and
continuing the communication with the base station in the second FDD group.
