Abstract:
1. A method performed by a base station for providing service in a wireless network, the method comprising: forming a cyclically extended structure that includes a first Time Division Multiplexed (TDM) synchronization code and a plurality of bits; transmitting the first TDM synchronization code over a synchronization channel during a first portion of a duration of a timeslot of a radio frame; transmitting the plurality of bits over a common control physical channel (CCPCH) during a second portion of the duration of the timeslot of the radio frame, wherein the second portion does not overlap the first portion in time, and wherein the plurality of bits include at least one data code to which a common scrambling code has been applied, and wherein the common scrambling code is a scrambling code used by at least one other base station, and wherein the base station transmits the plurality of bits in time-synchronization and frequency-synchronization with the at least one other base station; transmitting a second TDM synchronization code over the synchronization channel, wherein the first and second TDM synchronization codes are configured to be used by a wireless communication unit for channel estimation purposes; and wherein transmitting the plurality of bits over the CCPCH includes discontinuing transmission over the CCPCH during the first portion of the timeslot when the first TDM synchronization code is transmitted.
