Title:
DETECTION METHOD, DEVICE, AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/001240
Kind Code:
A1
Abstract:
The present application provides a detection method, a device, and a communication apparatus, pertaining to the technical field of communications. The detection method comprises: determining received signals according to pilot signals respectively sent by m user equipment (UE) units and channel responses to undergo detection of the m UE units, wherein m is a positive integer greater than 1; determining, according to the pilot signals of the m UE units and the received signals, an estimated value of the channel response of each of the UE units for every round of D rounds; and determining a detection result, wherein the detection result is an estimated value of the channel response of said UE unit for the D-th round, and D is a positive integer greater than 1. A network apparatus of the present application receives pilot signals sent by multiple UE units, and then processes the received signals by means of two interference control architectures, i.e., a base cancellation framework and a residual cancellation framework, so as to eliminate interference from non-orthogonal pilot signals and inter-cell interference. In this way, the invention realizes channel response detection of each UE unit, thereby increasing the number of pilot resources in a base station and system capacity.
