Title: A METHOD OF NEIGHBOR CELL DETECTION
Abstract:
A method is disclosed (20) of neighbor cell detection performed in a communication device (35) in a telecommunication system, wherein synchronization signals for cell detection are located in one or more subbands, each subband being part of the system frequency bandwidth, and repeated in repetition time periods. The method (20) comprises selecting (21) at least one subband-time interval resource for processing, wherein each subband is part of a system frequency bandwidth and each time interval is a part of a synchronization signal repetition time period, recording (22) one or more radio samples associated with the at least one subband-time interval resource, executing (23) detection of synchronization signals on the recorded radio samples, and repeating (24) the selecting (21), recording (22) and executing (23) until a stop criterion is fulfilled. A corresponding communication device (35) computer program (32) and computer program product (31) are also provided.
