Title:
METHOD AND DEVICE FOR PROCESSING QUASI-COLOCATION INFORMATION
Document Type and Number:
WIPO Patent Application WO/2018/028368
Kind Code:
A1
Abstract:
Provided in the present invention are a method and device for processing quasi-colocation information. The method comprises: a base station divides M demodulation pilot ports into N demodulation pilot port groups G1, …, and GN, where N1 demodulation port groups are signal demodulation port groups, N2 demodulation port groups are scrambling demodulation port groups, M, N1, and N2 are positive integers, and 1 < N ≤ M; and the base station transmits quasi-colocation information of the N demodulation pilot port groups to a terminal. The described technical solution solves the problem in the prior art in which the terminal cannot acquire quasi-colocation parameter information of an interfering DMRS and, as a result, cannot acquire the time offset and frequency offset of an interfering channel and correct the time offset and frequency offset of the frequency interfering with DMRS estimation, thus allowing the terminal to accurately acquire the quasi-colocation information of an interference and to accurately eliminate the impact of the interference, and increasing the performance of a radio communication system.
