US 2021/0345399 A1 · Multiple Channel State Feedback Reports For MU-MIMO Scheduling Assistance

Abstract

Methods related to wireless communication systems and selecting groups of user equipment (UE) devices to multiplex for multi-user multiple input and multiple output (MU-MIMO) communications are presented. A base station transmits a channel state report configuration indicating a set of one or more interference measurement resources and precoding information associated with the set of one or more interference measurement resources to a first UE of a plurality of UEs. The BS receives, from the first UE, a channel state report including interference prediction information based on the set of one or more interference measurement resources and the precoding information. The BS uses the channel state report to determine a group configuration for the plurality of UEs. Other features are also claimed and described.

Dependent claims

A method of wireless communication, comprising:

transmitting, by a base station (BS) to a first user equipment (UE) of a plurality of UEs, a channel state report configuration indicating a set of one or more interference measurement resources and precoding information associated with the set of one or more interference measurement resources;
receiving, by the BS from the first UE, a channel state report including interference prediction information based on the set of one or more interference measurement resources and the precoding information;
and
determining, by the BS, a group configuration for the plurality of UEs based at least in part on the received channel state report.
