Method for transmitting and receiving uplink signal on basis of interference measurement in base station cooperative wireless communication system and device for same

摘要

Disclosed is a method for enabling a specific reception point to receive an uplink signal from a terminal on the basis of interference control in a base station cooperative wireless communication system. Particularly, the method comprises the steps of: receiving, from an adjacent reception point, information regarding one or more resource groups for which the occurrence of the same interference is assumed; measuring, in a first resource belonging to the one or more resource groups, interference occurring from another uplink signal transmitted to the adjacent reception point; transmitting, to the terminal, scheduling information of an uplink signal in a second resource belonging to the one or more resource groups such that the measured interference is minimized; and receiving the uplink signal from the terminal in the second resource.

1. A method of receiving a first uplink signal, which is received by a specific reception point from a terminal based on interference control in a base station cooperative wireless communication system, the method comprising:
receiving information on a plurality of resource groups including a first resource group and a second resource group, wherein the first resource group includes a plurality of subframes configured for retransmissions according to a Hybrid Automatic Repeat and Request (HARQ) operation for a terminal communicating with a neighboring reception point; measuring interference, which is caused by a second uplink signal transmitted to the neighboring reception point by the terminal, in a resource corresponding to a subframe belonging to the plurality of subframes of the first resource group; transmitting uplink signal scheduling information in the second resource group to the terminal to minimize the measured interference; and receiving the first uplink signal from the terminal in resources of the second resource group.
