Apparatus for point-to-multi point communication in communication system and method thereof

摘要

An apparatus and a method for performing a point-to-multi point communication in a communication system are provided. The apparatus includes a base station configured to receive and transmit at least one of data on a mobile station, control information of the mobile station, schedule information on the mobile station, and control information on a communication link with at least one base station with respect to at least one base station in which a communication link is not set up through a core network. The base station services at least one mobile station at the same time together with a base station in which a communication link is set up through a core network.

主权项

1. A method of detecting a neighboring base station by a base station in a communication system, the method comprising:
receiving a discovery preamble transmitted from a transmission window section of the neighboring base station in a scanning window section; determining a start time of a response window section corresponding to a listening window section using at least one of section information on the listening window section of the neighboring base station included in the received discovery preamble, a start time of the transmission window section of the neighboring base station included in the section information, and a section length of the transmission window section; transmitting an access request with respect to the received discovery preamble from the response window section to the neighboring base station according to the determined start time; and receiving an access confirmation with respect to the access request transmitted from the neighboring base station, wherein the section information on the listening window section includes a start time of the listening window section and a section length of the listening window section.
