Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit, to a base station, a UE capability message indicating support for at least a first demodulation mode or a second demodulation mode. The first demodulation mode may correspond to a single demodulation procedure associated with a set of antenna ports at the UE, and the second demodulation mode may correspond to multiple demodulation procedures, each procedure associated with a respective subset of antenna ports at the UE. In some cases, the UE may flexibly switch between demodulation modes. The UE may receive, from the base station, one or more downlink signals via one or more downlink beams based on the indication of the first demodulation mode or the second demodulation mode. The UE may demodulate the one or more downlink signals based on the indicated (e.g., an active) demodulation mode.

Abstract: Techniques and apparatus for adapting bandwidth operation for full duplex user equipments (UEs) are described. One technique involves a base station (BS) determining a plurality of resource bandwidths (BWs) within an active BWP that are available to be used for communications by one or more UEs. An indication of at least one resource BW of the plurality of resource BWs is signaled to a UE. Communications between the BS and the UE are performed on the at least one resource BW.

Abstract: A user equipment (UE) receives reference signal resource configuration for transmitting reference signals for positioning from, e.g., a location server. The UE transmits or attempts to transmit reference signals for positioning to one or more transmission-reception points, such as a gNB. The UE may, however, may be unable to transmit reference signals in accordance with the reference signal resource configuration. For example, the UE may be unable to transmit the reference signals or may transmit the reference signals with lower power or a different spatial relation than configured. The UE may provide a reference signal transmission report indicating that the reference signals were not transmitted according to the reference signal resource configuration. The reference signal transmission report may indicate how the reference signal transmission differs from the reference signal resource configuration and may indicate the reasons that the reference signal transmission differs from the reference signal resource configuration.

Abstract: Techniques are discussed herein identify transmission strategies and to communicate those identified transmission strategies in a transparent communication environment. In some examples, a user equipment (UE) may identify a new transmission strategy for a downlink channel different from a current transmission strategy for the down link channel. The UE may transmit a channel state information (CSI) message that includes an indication of the new transmission strategy identified by the UE. In some examples, a base station may identify the new transmission strategy for the downlink channel. The base station may transmit a codebook subset restriction (CSR) indicator that includes an indication of the new transmission strategy identified by the base station. In some examples, the UE may modify its feedback strategy based on the new transmission strategy.

Abstract: Certain aspects of the present disclosure provide techniques for channel state information (CSI) reporting with time domain (TD) compression. A method that may be performed by a user equipment (UE) includes receiving one or more CSI-RS from a base station (BS). The UE measures the one or more CSI-RS. The UE determining a mapping order for placing CSI feedback in one or more CSI reports and sends the one or more CSI reports to the BS based on the measurements, the one or more CSI reports providing TD compressed CSI feedback including at least linear combination coefficients associated with TD bases used for the TD compression.

Abstract: Some aspects of the present disclosure provide channel state information (CSI) processing criteria. A method that may be performed by a user equipment (UE) generally includes receiving, from a base station via a first bandwidth part (BWP), control signaling that triggers reporting at least one of a first channel state information (CSI) report associated with the first BWP or a second CSI report associated with a second BWP that is non-active, determining, based on an indication of an active downlink (DL) BWP change, at least one occupation time of one or more CSI processing units (CPUs) associated with the first CSI report or the second CSI report, and taking one or more actions based at least in part on the at least one occupation time.

Abstract: Radio frequency (RF) sensing of a target object by a wireless network is supported by a sensing node and a network node using sensing assistance data. The sensing assistance data may include information for Doppler estimation from received RF signals. The information for Doppler estimation, for example, may include an indication of phase coherency of RF signals, such as phase coherence found in positioning reference signal (PRS) resources, resource sets, transmission reception points (TRPs), frequency layer or any combination thereof. The sensing assistance data may include an association of PRS resources and reference point objects (RPOs) so RF signals reflected from the RPOs may be excluded from the sensing measurements. The sensing assistance data may include beam pattern information for PRS resources for beam coordination for RF sensing.

Abstract: Methods, systems, and devices for wireless communications are described in which a transmitting device may determine a transmit power based on a power state of the transmitting device. A transmitting device may be configured with multiple power configurations, and a particular power configuration may be selected based on a power state and physical layer channel to be transmitted. Based on the selected power configuration, a transmit power may be determined in accordance with a transmit power procedure (e.g., an open loop power control procedure). The configuration may provide, for each physical layer channel (or reference signal), a power offset or delta that is applied in the open loop power control procedure.

Abstract: The techniques described herein provide procedures at user equipment (UEs) for performing channel state information (CSI) reporting and sounding reference signal (SRS) transmissions based on an ultra-reliable low latency communication (URLLC) block error rate (BLER) target and for reliably receiving PDCCH transmissions. For CSI reporting, a UE may be configured to generate a CSI report based on a BLER target and on received CSI reference signals (CSI-RSs), where the CSI-RSs may be transmitted on one or more groups of quasi co-located antenna ports. For SRS transmissions, a UE may be configured to transmit SRS based on an SRS configuration determined based on a BLER target. For receiving PDCCH transmissions, a UE may be configured to receive and combine DCI received from multiple base stations.
