POWER CONTROL METHOD AND APPARATUS IN WIRELESS ACCESS SYSTEM

摘要

The present invention provides methods for transmitting a scheduling request (SR) in a wireless access system supporting a multiple connection mode, in which a terminal is connected to two or more small cells, and apparatuses supporting the same. According to one embodiment of the present invention, a method for transmitting an SR, by a terminal, in a wireless access system supporting a multiple connection mode comprises the steps of: receiving an upper layer signal including an SR parameter for SR transmission from a first small cell which is in a multiple connection mode state; generating an SR on the basis of the SR parameter; and transmitting the SR using a physical uplink control channel (PUCCH) signal. Herein, the SR parameter is pre-set by negotiation between the first small cell and a second small cell which is in a multiple connection mode. Furthermore, in the multiple connection mode, the terminal maintains multiple connections with two or more small cells including the first small cell and the second small cell, and the first small cell and the second small cell may be connected to each other via a non-ideal backhaul link.
