Abstract

A Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) communication network implements a frame structure having a constant slot size. Signaling information, including e.g., synchronization information, for a particular connection is superimposed at a predetermined offset from the beginning of a selected slot in the frame, and the offset is transmitted on the Common Broadcast Channel (BCH). Also, the synchronization information preferably is transmitted in the same slot with the Random Access CHannel (RACH). To establish a communication link, a transmitter operating in the network selects a first code word and a first time location within an uplink time slot, superimposes the first code word on the first time location within the uplink time slot, and transmits the first code word in the chosen time location. A receiver searches for a match of the first code word in at least one time location in at least one time slot designated for the uplink, and determines a possibly empty set of likely candidates for code words and locations; and if the set of candidates is not empty, estimates the time difference between at least one of the candidates time locations and at least one of the predefined time locations.
