Patent ID: 8724594

Claim:
A method for measuring power of adjacent cells, comprising the step of: measuring Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) adjacent cells in a Wideband Code Division Multiple Access (WCDMA) mode when TD-SCDMA timing has not been obtained, wherein a terminal in an idle state uses dormant idle WCDMA sub-frames to receive data of TD-SCDMA adjacent cells specified by a network side so as to measure the TD-SCDMA adjacent cells, and in a connection state uses an idle window of the WCDMA subframes to receive the data of TD-SCDMA adjacent cells specified by the network side so as to measure the TD-SCDMA adjacent cells, said method further comprising the following steps A-C; step A, receiving the data of the TD-SCDMA adjacent cells, performing automatic gain control adjustment and coarse synchronization adjustment of frequency points of the TD-SCDMA adjacent areas, thereby obtaining a stable automatic gain control value of one frequency point, and the success of the coarse synchronization of the frequency point; step B, receiving data relevant to a downlink synchronization code according to a coarse synchronization position, finding out a position where a relevant peak is the highest which is to be used as a TD-SCDMA timing, and determining an observation time difference of all the TD-SCDMA adjacent cells with respect to the TD-SCDMA timing under the frequency point; and step C, receiving data in the 0th time slot relevant to a training sequence code under the frequency point according to the TD-SCDMA timing, which is for determining a received signal code power of the TD-SCDMA adjacent cells whose observation time difference has been obtained, wherein the present step is performed three times and an average value of the measurements of the received signal code powers of the three times is reported to the network side.
