Abstract: This disclosure relates to techniques for a wireless device to perform channel state information reporting. The wireless device may receive channel state information reporting configuration information. The channel state information reporting configuration information may include an indication to use a wideband precoding matrix indicator format for 3GPP release 16 type II channel state information reporting. The wireless device may perform channel state information reporting using a different reporting configuration than 3GPP release 16 type II channel state information reporting using a wideband precoding matrix indicator format based at least in part on the channel state information reporting configuration information. The wireless device may also or alternatively perform 3GPP type I channel state information reporting using a unified spatial basis selection framework for rank indicators of 3 and 4 for any number of channel state information reference signal ports.

Abstract: Systems and methods are provided for to support user equipment (UE) channel state information (CSI) report of time domain channel properties concurrently with Interference Measurement Resources (IMRs) measurements. Embodiments herein consider Uplink Control Information (UCI) multiplexing, UCI omission, Interference Measurement Resource (IMR) configuration, and phase continuity handling. A CSI report configuration (CSI-ReportConfig) may comprise configuration details for both one or more Channel Measurement Resources (CMRs) and one or more Interference Measurement Resources (IMRs). The CMRs may be used to measure time domain channel properties (TDCP) based on a CSI reference signal (CSI-RS) for tracking reference signal (TRS).

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.
