Claim 8:
9. A method of wireless communication at a serving cell having a first remote radio header (RRH) and a second RRH, comprising:
transmitting, on a downlink communication channel, a first timing advance group (TAG) and associated timing advance (TA) offset for the second RRH to a user equipment (UE);
transmitting a second TAG and associated TA offset for the second RRH to the UE following transmission of the first TAG, wherein the first RRH is associated with a first subset of reference signals (RSs) of a set of RSs and the second RRH is associated with a second subset of RSs of a set of RSs different from the first subset of RSs, and wherein the second subset of RSs is associated with the first TAG and the first subset of RSs is associated with the second TAG;
detecting a switch of the UE from the first RRH to the second RRH; and
receiving, on an uplink communication channel, data from the second RRH.
