Abstract: A transmitting device for wireless communication calculates distortion error based on a non-distorted digital transmit waveform and a non-linearity. The transmitting device compresses the distortion error with an encoder neural network of an auto-encoder. The transmitting device transmits, to a receiving device, the compressed distortion error to compensate for the non-linearity in a power amplifier (PA).

Abstract: Apparatus, methods, and computer-readable media for providing improved power efficiency during DRX wake-up are disclosed. An example method of wireless communication at a UE includes receiving a WUS from a base station while performing a DRX cycle, the WUS indicating data for transmission to the UE. The example method also includes at least one receiving a downlink reference signal or transmitting an uplink reference signal based on the WUS and prior to reception of the data, the uplink reference signal transmitted or the downlink reference signal received during an on-duration of the DRX cycle and in response to receiving the WUS. The example method also includes sending a CSI report to the base station based on the WUS and prior to the receiving of the data. The example method also includes receiving the data following the respective receiving or transmitting of the downlink reference signal or uplink reference signal.

The second device may select a base graph from a plurality of base graphs based on the base graph recommendation. The second device may transmit an indication of the selected base graph from the plurality of base graphs after the selection of the indication of the base graph recommendation. The first device may receive the indication of the selected base graph from the plurality of base graphs after an output of the indication of the base graph recommendation.

Abstract: Techniques for channel state feedback using sensing reference signals are disclosed. The techniques can include identifying a channel state information (CSI) report configuration based on CSI reporting configuration information received from a radio access network (RAN) node of a RAN, based on the CSI report configuration, identifying a set of basis reference signals to be measured on a wireless channel of the RAN, wherein the set of basis reference signals includes one or more sensing reference signals, measuring the set of basis reference signals to obtain channel state measurements, determining channel state information based on the channel state measurements, and transmitting a CSI report including the channel state information to the RAN node.

Abstract: A victim user equipment (UE) may experience cross-link interference (CLI) from transmissions from an aggressor UE. The present disclosure provides for configuration of a CLI report that accurately characterizes the CLI experienced by the victim UE. A base station may transmit to the victim UE, a configuration for CLI reporting associated with one or more channel state information interference measurement (CSI-IM) resources. The victim UE may generate a CLI report based on the configuration for CLI reporting and the CSI-IM resources. The victim UE may transmit the CLI report to the base station. The base station may use the CLI report to mitigate the CLI, for example, by scheduling the aggressor UE and the victim UE to reduce CLI experienced by the victim UE.

Abstract: Apparatuses and methods for mobility enhancements and power saving considerations for UE are described. An apparatus is configured to operate on an active DL BWP in a source node, where the active DL BWP is not a default DL BWP associated with the UE, and start a BWP inactivity timer at the UE that triggers a BWP switch from an active DL BWP to the default DL BWP after the BWP inactivity timer expires at a first expiration time. The apparatus is also configured to report a measurement of at least one of the source node or a target node, and start a mobility reception timer based on a condition associated with at least one of the measurement of the source node being below a first signal quality threshold or the measurement of the target node being above a second signal quality threshold.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit capability information including an indication of a discontinuous monitoring delay period. The UE may receive a message including an indication to adjust monitoring of a physical downlink control channel (PDCCH), and monitor for the PDCCH during the discontinuous monitoring delay period. The UE may adjust monitoring for the PDCCH following the discontinuous monitoring delay period during a temporal period based on the received indication to adjust monitoring of the PDCCH. In some examples, at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled during the temporal period while monitoring of the PDCCH is adjusted.
