Patent ID: 7200124

Claim:
A method for measuring by a UE (User Equipment) a synchronization signal on a control channel and second Node B information from a second Node B in a system including a first Node B, the second Node B adjacent to the first Node B, and the UE in a cell occupied by the first Node B, the first Node B and the UE using a TDD (Time Division Duplexing) CDMA (Code Division Multiple Access) communication technique over a frame having a plurality of time periods, a downlink channel being transmitted from the first Node B to the UE over at least one time period among the plurality of time periods in the frame, an uplink channel being transmitted from the UE to the first Node B over at least one time period among the remaining time periods except the at least one time period over which the downlink channel is transmitted, the UE and the second Node B performing communication by a TDD communication technique using a frequency band different from that of the TDD CDMA communication technique, the synchronization signal for synchronizing the UE with the second Node B and the control channel indicating the second Node B information being transmitted from the second Node B to the UE over at least one time period among the plurality of time periods, the method comprising the step of: changing a position of the downlink time period over which the downlink channel is transmitted from the first Node B to the UE, and changing a position of the uplink time period over which the uplink channel is transmitted from the UE to the first Node B, so that the time period of the control channel transmitted from the second Node B to the UE is located within a previous subframe and within one of a next subframe and a frame.
