APPARATUS AND METHOD FOR ALIGNING DISCOVERY CHANNEL INTERVALS AMONG CELLS IN CELLULAR COMMUNICATION SYSTEM

摘要

A method for aligning discovery channel intervals of a serving cell and a neighbor cell in a cellular communication system is provided. The method includes selecting at least one user equipment (UE), by a serving evolved node b (eNB) managing the serving cell, wherein the UE is located in the serving cell and operates in a radio resource control (RRC) connected mode, transmitting, to the at least one UE, a request message requesting information related to a discovery channel of the neighbor cell, receiving, from the at least one UE, at least one of an identifier (ID) of the neighbor cell, a temporally adjusted value obtained by shifting the discovery channel with respect to a frame reference time of the neighbor cell, and a network time difference (NTD) between the serving cell and the neighbor cell, and aligning the discovery channel interval of the serving cell to the discovery channel interval of the neighbor cell based on the at least one of the ID of the neighbor cell, the temporally adjusted value, and the NTD.

1. A method for aligning discovery channel intervals of a serving cell and a neighbor cell in a cellular communication system, the method comprising:
selecting at least one user equipment (UE), by a serving evolved node b (eNB) managing the serving cell, wherein the UE is located in the serving cell and operates in a radio resource control (RRC) connected mode; transmitting, to the at least one UE, a request message requesting information related to a discovery channel of the neighbor cell; receiving, from the at least one UE, at least one of an identifier (ID) of the neighbor cell, a temporally adjusted value obtained by shifting the discovery channel with respect to a frame reference time of the neighbor cell, and a network time difference (NTD) between the serving cell and the neighbor cell; and aligning the discovery channel interval of the serving cell to the discovery channel interval of the neighbor cell based on the at least one of the ID of the neighbor cell, the temporally adjusted value, and the NTD.
