NEIGHBOR DISCOVERY METHOD AND APPARATUS FOR USER MOBILE TERMINAL DEVICE TO USER MOBILE TERMINAL DEVICE COMMUNICATION SYSTEM

摘要

There is provided a neighbor discovery method and apparatus for a user mobile terminal device to user mobile terminal device communication system comprising multiple eNode Bs and a plurality of user mobile terminal equipments. The method comprises receiving a system message at each of the plurality of user mobile terminal equipments from a respective eNode B of the multiple eNode Bs, wherein the system message comprises a configuration information indicating how a plurality of neighbor discovery channels are configured in radio resources; selecting, at each of the plurality of user mobile terminal equipments, a respective neighbor discovery channel from the plurality of neighbor discovery channels based on the configuration information in the system message; transmitting, at each of the plurality of user mobile terminal equipments, respective beacon signals on the selected neighbor discovery channel; and receiving, on unselected neighbor discovery channels, at each of the plurality of user mobile terminal equipments, beacon signals from neighbor mobile terminal devices of a respective user mobile terminal equipment. The neighbor discovery method and apparatus of the present invention can achieve good performance with neighbor discovery latency constraint.
