Abstract

A method and apparatus are provided for transmitting control information by an evolved Node B (eNB) to a user equipment (UE) for interference measurement in a wireless communication system. The eNB determines whether the UE can perform interference management for receiving a data signal transmitted from the eNB based on the information of the interference signal. When it is determined that the UE can perform interference management, the eNB transmits to the UE configuration information for receiving data signals by applying the interference management by the UE, and then transmits downlink control information including transmission power control information including transmission power control information to the UE Indicates whether the transmission power of the demodulation reference signal (DMRS) corresponding to the interfering signal is different from the transmission power of the interfering signal.

Description

technical field [0001] The present disclosure relates to a method and apparatus for transmitting control information for interference measurement in a wireless communication system. More particularly, the present disclosure relates to a method and apparatus for estimating information of an interference signal in order to improve reception capability of a user equipment (UE) receiving a downlink signal. Background technique [0002] Mobile communication systems have evolved beyond early voice-oriented services into high-speed, high-quality wireless packet data transmission systems for providing data services and multimedia services. Recently, such as High Speed ​​Downlink Packet Access (HSDPA) and High Speed ​​Uplink Packet Access (HSUPA) defined in the 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE) and Long Term Evolution-Advanced (LTE-A), Various mobile communication standards such as High-Speed ​​Packet Data (HRPD) defined in 3rd Generation Partnersh...
