WIRELESS COMMUNICATION DEVICE Russian patent published in 2014 - IPC H04W76/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to wireless communication for transmitting a random access signal when a mobile terminal synchronises itself with a base station, and is intended to increase the percentage of normal reception of random access signals by a handover destination base station by suppressing interference between random access signals transmitted from a plurality of mobile stations. Upon handover, a mobile station receives, from the movement origin base station, information on the movement destination base station and information relating to a sequence to be used for transmitting a random access signal to the movement destination base station. The mobile station receives a synchronisation channel signal transmitted from the movement destination base station. The mobile station then transmits the random access signal to the movement destination base station with a timing offset by a prescribed period from a time of receiving a synchronisation channel and at a frequency corresponding to that of the synchronisation channel. A position of the time/frequency used for transmitting the random access signal for the handover is used exclusively by the random access signal transmitted from the mobile terminal for which handover is being performed or is used exclusively at the same time by a plurality of mobile stations for which handover is performed.

EFFECT: improved communication.
