Apparatus and method in wireless communication system
First Claim
1. An apparatus in a wireless communication system, comprising:
- circuitry, where the circuitry is configured to;
trigger a dynamic network planning for a plurality of user equipments in a region managed by the apparatus based on a predetermined trigger event;
estimate a distribution status of the plurality of user equipments in the region based on position information of the plurality of user equipments in the region;
calculate an interval distance at least in part based on the distribution status; and
in response to the predetermined trigger event, select a first master user equipment at least in part based on the distribution status and such that a distance between the first master user equipment and a second master user equipment is larger than the interval distance,wherein the first master user equipment receives a signal from a base station and relays a signal between the base station and a slave user equipment during a device to device communication.

Abstract
An apparatus and method in a wireless communication system. The apparatus includes a dynamic network planning trigger unit and a master user equipment selecting unit. The dynamic network planning trigger unit triggers, based on a predetermined trigger event, a dynamic network planning in an area managed by the apparatus. The dynamic network planning includes selection of a master user equipment used for device-to-device communication, and the master user equipment receives signals from a base station during the device-to-device communication process and relays signals between the base station and a slave user equipment. The master user equipment selecting unit selects, from user equipment in the area according to quality of channels between the user equipment and the base station, one or more user equipment as master user equipment, distances between the master user equipment being greater than the intervals.
