Abstract:
1. A wireless communication method wherein a terminal is within wireless communication range of at least one serving cell with which the terminal has at least uplink communication, and at least one neighbour cell with which the terminal has no uplink communication, the cells controlled by one or more base stations and transmitting at least reference signals for reception by the terminal, the method comprising: at the terminal, transmitting signals on the uplink to the serving cell, and measuring signals received from the cells; at a base station of the serving cell, measuring signals received on the uplink from the terminal; and the method further comprising: determining, based on information about the transmitted and received signals, that the terminal is in the vicinity of an uplink border between the serving cell and neighbour cell at which signal strength of the neighbour cell becomes an offset better than the serving cell on the uplink; said determining being performed either: at the base station of the serving cell, wherein information about the transmitted and received signals includes: information about transmitted power of the neighbour cell's transmitted signal received by the base station from the neighbour cell's, and information from the terminal about transmitted power of the signals transmitted by the terminal and the received power of the signals received from the cells: or at the terminal, wherein information about the transmitted and received signals includes: information from the serving cell about transmitted power of the serving cell's transmitted signals received by the terminal, information from the serving cell or from the neighbour cell about the transmitted power of the neighbour cell's transmitted signals, and information from the serving cell about the received power of the terminal's uplink communication.
