Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, information indicating a Layer 1 signal to interference plus noise ratio (L1-SINR) measurement capability of the UE. In some aspects, the information indicating the L1-SINR measurement capability may include one or more individual configurations for one or more resources to carry a reference signal. The UE may receive, from the base station, a reference signal carried on the one or more resources based at least in part on the L1-SINR measurement capability. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for determining an energy per resource element (EPRE) ratio for non-zero power (NZP) channel state information reference signals (CSI-RSs) when a device is measuring a wireless channel. A method that may be performed by a user equipment (UE) includes determining, based on an indication, an energy per resource element (EPRE) ratio for a non-zero power (NZP) channel state information reference signal (CSI-RS) resource; and measuring a channel based on the determined EPRE ratio and CSI-RSs associated with the NZP CSI-RS resource.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive from a network entity, a control message triggering the UE to provide a time-domain aperiodic channel state information (A-CSI) report for indicating time-domain channel state information (CSI) associated with CSI reference signal (CSI-RS) resources within an observation window, where a beginning of the observation window is based on when the control message is received. The UE may perform performing measurements of channel state information reference signals (CSI-RSs) received via the CSI-RS resources that occur within the observation window. The UE may then transmit, to the network entity based on the control message, the time-domain A-CSI report indicating measured time-domain CSI associated with the observation window, where the measured time-domain CSI is based on the measurements.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects relate to a channel state information (CSI) framework for full-duplex operations of a network node. Some aspects more specifically relate to a CSI configuration that includes one or more separate elements for calculating CSI associated with downlink time intervals and for calculating CSI associated with full-duplex time intervals. In some aspects, the CSI configuration may include separate channel measurement resources and/or separate interference measurement resources for calculating CSI associated with downlink time intervals and for calculating CSI associated with full-duplex time intervals. In some aspects, a network node may configure a user equipment with a common CSI reporting configuration or a separate CSI reporting configuration.

Abstract: Certain aspects of the present disclosure provide techniques for channel state information (CSI) processing occupation determination that can be used even in multiple transmission reception point (mTRP) scenarios. A method that may be performed by a user equipment (UE) includes receiving a channel state information (CSI) reporting configuration configuring the UE with a plurality of CSI reference signal (CSI-RS) resources for channel measurement (CMRs). The method includes determining a number of occupied CSI processing units, a number of occupied active CSI resources, and/or a number of occupied active CSI-RS ports based on an actual number of CSI measurements. The method includes performing CSI measurement based on the determination.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that an enhanced type-II channel state information (CSI) report configuration, associated with transmitting CSI feedback to a base station, is to be overridden; and transmit, based at least in part on determining that the enhanced type-II CSI report configuration is to be overridden, a CSI report using another CSI report configuration, wherein the CSI report includes the CSI feedback and an indication that the enhanced type-II CSI report configuration has been overridden. Numerous other aspects are provided.

Abstract: In order to enable a UE receiving a narrowband signal transmitted using in-band resources to use the LTE reference signals to assist the UE in receiving the narrowband signal using an in-band deployment, a phase rotation employed by the base station may be fixed relative to a known reference position in time. An apparatus for wireless communication at a base station may determine a phase offset for a narrowband signal for transmission using wideband resources, the phase offset having a relationship to a reference point in time and transmit the narrowband signal using the determined phase offset. An apparatus for wireless communication at a UE may receive a narrowband signal having a frequency location within a wideband signal and rotate a symbol of the wideband signal by a per symbol phase offset having a relationship of the phase offset to a reference point in time.
