Systems and methods are provided for to support user equipment (UE) channel state information (CSI) report of time domain channel properties. Embodiments herein consider Uplink Control Information (UCI) multiplexing, UCI omission, Interference Measurement Resource (IMR) configuration, and phase continuity handling. A channel state information report configuration (CSI-ReportConfig) may comprise details regarding measurement and reporting of time domain channel properties (TDCP) based on channel state information reference signal (CSI-RS) for tracking reference signal (TRS).

Method and apparatus to support UE CSI report of time domain channel properties

Systems and methods are provided for to support user equipment (UE) channel state information (CSI) report of time domain channel properties. Embodiments of a UE herein may receive, from a network node, a CSI report configuration (CSI-ReportConfig). The CSI-ReportConfig may comprise details regarding measurement and reporting of time domain channel properties (TDCP) based on a CSI reference signal (CSI-RS) for tracking reference signal (TRS). The UE may determine invalid CSI-RS resources and valid CSI-RS resources based on a timing of a duplex direction change. The UE may measure and report TDCP based on the valid CSI-RS resources.

Phase continuity handling for a UE CSI report of time domain channel properties measurements

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.

Enhancement to multi-user MIMO by channel state information reporting

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.

Subband channel state information reporting

The present application relates to devices and components including apparatus, systems, and methods for determining a beam for communication between a user equipment and a base station. For example, angle of arrival estimates may be utilized for determining the beam for communication.

Sensor assisted beam tracking

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.
