Method in which a terminal transceives a signal in a wireless communication system and apparatus for same

摘要

The present application relates to a method in which a terminal receives a signal in a wireless communication system. More particularly, the method comprises: a step of receiving, from a serving cell, interference mitigation information for mitigating interference from a neighboring cell; and a step of applying an interference mitigation technique based on the interference mitigation information so as to receive a signal from the serving cell. It is assumed that the serving cell does not apply said interference mitigation technique from after the reception of the interference mitigation information to the application of the interference mitigation technique.

1. A method of receiving a signal by a user equipment in a wireless communication system, the method comprising:
receiving, from a serving cell, interference mitigation information to mitigate interference from a neighboring cell, wherein the interference mitigation information includes MBSFN (Multimedia Broadcast Multicast Service Single Frequency Network) subframe configuration information; and receiving a downlink signal from the serving cell by applying an interference mitigating scheme based on the interference mitigation information, wherein the downlink signal is received without applying the interference mitigating scheme when the downlink signal is received at a MBSFN subframe indicated by the MBSFN subframe configuration information, wherein the interference mitigating scheme is applied when the downlink signal is received at a non-MBSFN subframe indicated by the MBSFN subframe configuration information, and wherein the applying the interference mitigating scheme includes:
receiving, from the serving cell, interfering cell CRS pattern information indicating CRS pattern of the neighboring cell to which a specific interference mitigation scheme is always applied; andapplying the specific interference mitigation scheme indicated by the interfering cell CRS pattern information to the downlink signal, wherein the specific interference mitigation scheme is one of a transmitting rate-matching method, a receiving side puncturing method or a receiving side interference invalidating method.
