INTERFERENCE PRE-CANCELLATION AND PRECODER PROJECTION COMPENSATION FOR MULTI-USER COMMUNICATIONS IN WIRELESS NETWORKS

摘要

A method may include receiving, by a mobile broadband user device, a control information including at least: a precoder projection angle that was used by the base station to project an original precoder matrix by the precoder projection angle; and information indicating that a scheduled transmission of a mobile broadband data block to the mobile broadband user device is co-scheduled with a transmission of an ultra low latency data block to an ultra low latency user device via a set of shared physical resource blocks using multi-user multiple -input, multiple-output (MU-MIMO); determining, by the mobile broadband user device, an updated decoder matrix for the mobile broadband user device based at least on the precoder projection angle; and decoding, by the mobile broadband user device based on the updated decoder matrix, the co-scheduled mobile broadband data block that was transmitted by the base station based on the projected precoder matrix.
