DEVICE AND METHOD FOR TRANSMITTING AND RECEIVING DISCOVERY SIGNAL OF BASE STATION IN MOBILE COMMUNICATION SYSTEM

摘要

A method by which a small base station (BS) transmits a discovery signal (DS) in a mobile communication system is provided. The method includes a macro BS to which a component carrier (CC) of a predetermined frequency band is allocated, and at least one small base station to which N number of CCs of a frequency band different from that of the CC allocated to the macro base station are allocated. The method comprises the steps of generating the DS corresponding to predetermined information and transmitting the generated DS through a discovery channel (DCH) configured as a transmission resource of the macro base station, wherein the predetermined information is one among information on at least one CC that the small base station uses, cell ID (CID) index information of the small base station, and a sleep base station index when the small base station is in a sleep mode.

1. A method for a second base station (BS) to transmit a discovery signal (DS) in a mobile communication system that includes a first BS, to which a component carrier (CC) of a predetermined frequency band is assigned, and at least one second BS to which N CCs are assigned, of which a frequency band is different from the CC assigned to the first BS, the method comprising:
generating a DS corresponding to predetermined information; and transmitting the generated DS through a discovery channel (DCH) that is formed of transmission resources of the first BS, wherein the predetermined information is one of at least one CC information used by the second BS, a cell ID (CID) configuration information index of the second BS, and a dormant BS index when the second BS is in a dormant mode.
