Method for performing handover in a C-RAN system, and apparatus therefor

摘要

The present invention relates to a method for a terminal to perform a handover in a cloud radio access network (C-RAN), including the steps of: receiving information on at least one candidate remote radio head (RRH); measuring the strength of received signals from at least one candidate RRH and a serving cell for the terminal; and, when the strength of the received signals from the candidate RRH and the serving cell of the terminal satisfy a predetermined relationship according to the measured result, transmitting feedback information, including the measured result, to the candidate RRH.

1. A method of performing a handover by a user equipment in a cloud radio access network (C-RAN) system, the method comprising:
receiving, from a serving remote radio head (RRH), information on at least one candidate RRH; measuring reception signal strengths of a serving cell of the at least one candidate RRH and the user equipment; transmitting feedback information containing the result of the measurements to the serving RRH when a prescribed relationship between a reception signal strength of the serving RRH of the user equipment and a reception signal strength of the serving cell is satisfied as a result of the measurements; receiving, from the serving RRH, a message including a command to activate at least one RRH to perform communication together with the serving RRH in response to the feedback information; and transmitting data to the at least one activated RRH and the serving RRH simultaneously.
