Abstract
One method of wireless communication involves acknowledging that an anchor base station received a handover indication signal. Another method involves: receiving, from base stations of an active set, offset signals identifying a respective differences in time between a reference time and respective times when the base station received a ranging signal from a mobile station; and transmitting, to the mobile station, a ranging control signal in response to the respective offset signals. Another method involves transmitting, to a mobile station in response to an active set signal, a system configuration information signal including system configuration information of a base station in an active set. Another method involves determining an uplink control channel power parameter in response to channel condition signals received from base stations in an active set. Another method involves transmitting a control signal to base stations in an active set on respective control channels. Apparatuses are also disclosed.
