Abstract: A user equipment (UE) transmits concurrent channel state information (CSI) processing capability information to a base station. The capability information can take various forms, and is intended to constrain the base station in the types of CSI requests that can be made to the UE. For example, the UE may indicate different CSI processing capabilities for intra-CC and inter-CC cases and/or for different codebook types. The UE may also specify supported combinations of codebook types for concurrent CSI reporting. The UE may also specify maximum resources or weighting factors for different codebook types. The UE may further restrict the rank information it provides and use a priority rule for "dropping" CSI report data due to payload size restrictions. The base station may direct, or the UE may implement, improved utilization of CSI resources that are shared for multiple concurrent CSI reports. Minimum time requirements for CSI reporting may also be relaxed.

Abstract: Methods and systems are for configuring multi-user multiple-input multiple output (MU-MIMO) operation by a base station and a plurality of UEs include requesting sounding reference signals (SRS) or channel state information (CSI) data from each UE of the plurality; configuring, based on the SRS or CSI data from each UE, a precoder matrix, the precoder matrix allocating a plurality of precoded CSI-reference signal (CSI-RS) resources for each UE; scheduling, for each UE, the precoded CSI-RS resources; receiving, from each UE, a CQI report that is based on the precoded CSI-RS resources received by that respective UE; generating a CQI matrix from the CQI reports of each UE; selecting a subset of UEs from the plurality based on the CQI matrix; and scheduling DL resources for the subset of UEs, the DL resources including reference signals.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform CSI-reporting. In an example, a BWP includes " M " subbands and is configured to the UE. The UE can process " Kc " CSI-RS samples to generate " M " subband CSI reports, where " Kc > M ." The UE determines what number of CSI-RS samples to use per subband based on the channel information of the BWP, where this number can vary between the subbands.
