Abstract

Derivation indicating the distance between co-channel signals within a multi-user, multiple-input multiple-output (MU-MIMO) transmission at the user equipment by utilizing demodulation interference measurement resources (DM-IMR) and based on demodulation reference signals (DMRS) Multi-User Channel Quality Information (MU‑CQI) for demodulation interference. The derivation of the signal, interference and signal-plus-interference parts of the MU-CQI can be configured as a MU-CQI report, for determining the physical resource block (PRB), period, subframe and / or antenna port to be used for the MU-CQI choose. The interfering transmissions may originate from the same transmission point as the desired signal or from a different transmission point.

Description

technical field [0001] The present disclosure relates generally to reporting channel state information in wireless communication systems, and more specifically, to considering demodulation interference in reporting channel quality. Background technique [0002] For multi-user, MIMO transmissions, existing channel quality reporting procedures in wireless communication systems do not adequately consider demodulation interference at user equipment. [0003] Therefore, there is a need in the art for improved channel quality reporting in wireless communication systems. Contents of the invention [0004] Technical solutions [0005] Derivation indicating the distance between co-channel signals within a multi-user, multiple-input multiple-output (MU-MIMO) transmission at the user equipment by utilizing the demodulation interference measurement resource (DM-IMR) and based on the demodulation reference signal (DMRS) Multi-User Channel Quality Information (MU-CQI) for demodulation...
