Abstract: Aspects are provided which allow a UE to provide a CSI report including an expiration time to a base station to reduce the risk of improper scheduling decisions at the base station based on outdated CSI reports. The UE obtains a channel measurement signal from the base station. The UE identifies CSI based on the channel measurement signal and provides a CSI report to the base station including the CSI. The CSI report further includes an expiration time for the CSI report. The base station obtains the CSI report from the UE including the expiration time for the CSI report, and the base station processes downlink data for transmission based on the expiration time in the CSI report.

Abstract: A method of wireless communication by a transmitting device transforms a transmit waveform by an encoder neural network to control power amplifier (PA) operation with respect to non-linearities. The method also transmits the transformed transmit waveform across a propagation channel. A method of wireless communication by a receiving device receives a waveform transformed by an encoder neural network. The method also recovers, with a decoder neural network, the encoder input symbols from the received waveform. A transmitting device for wireless communication calculates distortion error based on a non-distorted digital transmit waveform and a distorted digital transmit waveform. The transmitting device also 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 power amplifier (PA) non-linearity.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be known as user equipment (UE), may be capable of full-duplex communications. The UE may determine that at least a portion of a downlink transmission that the UE may receive while concurrently scheduled to transmit an uplink transmission, may overlap with a clear channel assessment (CCA) procedure (e.g., a listen-before-talk (LBT) operation) in a shared radio frequency spectrum band. The UE may determine that at least a portion of the downlink transmission that overlaps with the LBT resources may be canceled or the downlink transmission may be rate matched and allocated to resources outside of the LBT resources. As a result, the UE may perform an LBT procedure without interference caused by the UE receiving the downlink transmission.

Abstract: Aspects are provided which allow for multiplexing of higher priority uplink transmissions with lower priority uplink transmissions while maintaining URLLC of the higher priority uplink transmission. A UE receives from a base station information including resources for first and second uplink data, where at least a portion of the resources for the first and second uplink data overlap in time. The first and second uplink data are associated with different priority levels. The UE determines whether to multiplex the uplink data based on a transmission timing difference between a scheduled transmission time and a multiplexed transmission time for the second uplink data on the respective resources. The base station makes a similar determination. If the transmission timing difference fails to meet a delay threshold, multiplexing is performed; otherwise, the lower priority transmission is dropped. Thus, different priority multiplexing may occur in low latency situations, satisfying URLLC.

Abstract: A UE may identify slots to transmit and/or receive information related to one or more HARQ processes in frame structure that includes both sub-band full duplex slot types and time division duplex slot types. Based on a first slot used for control information, a UE can identify a second slot for PUSCH or PDSCH communication based on an offset between the first slot and the second determined by calculating slot offsets (e.g., based on parameters received from a base station). In some aspects, a UE may exclude certain slot duplex types (e.g., SBFD or TDD) when calculating slot offsets. In some aspects, a UE may calculate slot offsets differently for different HARQ processes corresponding to one frame. In some aspects, slot offset behaviors may be based on priority of information associated with a HARQ process.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitter may select a precoder from a codebook for precoding one or more signals for transmission to a receiver. The transmitter may select the precoder from the codebook based on antenna configurations at the transmitter and the receiver. The precoder may be constructed using one or more Slepian sequences. In some implementations, the Slepian sequences may be associated with a quantity of transmit antennas at the transmitter. For instance, a length of each Slepian sequence may correspond to (for example, be equal to) a quantity of transmit antennas at the transmitter. Further, the Slepian sequences may be associated with a bandwidth within which to concentrate the one or more signals. Once the transmitter selects the precoder, the transmitter may precode the one or more signals and transmit the precoded signals to the receiver.

Abstract: Aspects of the disclosure relate to a reconfigurable intelligent surface (RIS) controller for controlling a RIS panel to be frequency and/or element dependent, and for operating an adaptive filtering function. The RIS controller may be configured to transmit, to a scheduling entity, a RIS frequency capability indication for indicating communication support of the RIS panel for one or more frequency ranges. The scheduling entity, then, may transmit RIS control information based on the RIS frequency capability indication. In response, the RIS controller may receive the RIS control information and configure the RIS panel based on the RIS control information. Other aspects, embodiments, and features are also claimed and described.
