Embodiment approach

[0105] According to one embodiment of the present invention, according to the method of defining the time-frequency resource corresponding to one IMR to measure the interference to the UE (per CSI process IMR definition method), the same as the traditional LTE Release 11, the eNB is MU- MIMO interference measurement defines an IMR for each CSI process of the UE. According to one embodiment of the invention, the interference measured using the IMR defined for the interference to the UE can be calculated in such a way that signals transmitted to other UEs are added as interference, or signals received by the UE are removed.

[0106] Interference measurement scheme 1 based on one IMR: Interference is measured by adding signals directed to other UEs as interference targets.

[0107] Interference measurement scheme 2 based on an IMR: measure interference by removing signals directed to the UE.

[0108] One IMR based interference measurement scheme 3: Interference is measured using...

Abstract

A base station and a channel status information acquisition method thereof for acquiring channel status information in a mobile communication system operating in a multiuser multiple-input multiple-output transmission mode are provided. The method includes generating interference measurement configuration information for measuring interference caused by signals transmitted from a serving base station of the terminal to at least one other terminal in the multiuser multiple-input multiple output transmission mode; transmitting the generated interference measurement configuration information to the terminal; and receiving channel status information generated using the transmitted interference measurement configuration information from the terminal. The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.

Description

technical field [0001] The present invention relates generally to interference measurement and, more particularly, to an interference measurement method and method for a terminal in a mobile communication system comprising an evolved Node B (eNB) having multiple transmit antennas for Multiple Input Multiple Output (MIMO) transmission. device. Background technique [0002] In order to meet the demand for wireless data traffic that has increased significantly since the deployment of 4G communication systems, efforts have begun to deploy improved 5G or pre-5G communication systems. Therefore, the 5G or pre-5G communication system is also called "super 4G network" or "post-LTE system". 5G communication systems are expected to be implemented in higher frequency (millimeter wave) frequency bands, such as 60GHz, enabling higher data rates. In order to reduce the propagation loss of radio waves and increase the transmission distance, beamforming, massive multiple-input multiple-ou...
