Multiple channel quality indicator (CQI) reports for link adaptation
Abstract:
Methods related to wireless communication systems and performing link adaption for multiple user-multiple-input multiple-output (MU-MIMO) communications using multiple expected channel quality indicators are presented. A base station (BS) transmits, to a first user equipment (UE) of a plurality of UEs, a channel state report configuration indicating a set of one or more measurement resources and at least one of precoding information or rank indications associated with the set of one or more measurement resources. The BS receives, from the first UE, a channel state report including a plurality of expected channel quality indicators (CQIs) over a time period based on the set of one or more measurement resources and the at least one of the precoding information or rank indications. The BS uses the channel state report to determine a link adaptation for the first UE. Other features are also claimed and described.
