A system and method for reducing the unused capacity of a wireless communication channel utilize the data fields of an special burst (SB) in order to signal physical layer control signaling for coordination between a Node B and a user equipment (UE). The control signaling may include improved reception of SBs, enclose transmit power control commands or any physical layer control signaling for coordination between the UE and the Node B for synchronization timing advance or reconfiguration of the physical channel. This system and method may be applied independently to the uplink and the downlink.
