Abstract: An apparatus and method for Uu and sidelink prioritization for subband full duplex UEs. The apparatus determines a priority level associated with channels that are scheduled to collide with each other. The apparatus transmits or receives a channel having a highest priority between the channels that are scheduled to collide with each other. The channel comprises at least one of an UL transmission, a DL reception, an SL transmission, or an SL reception. The apparatus enables simultaneous reception or transmission of the channel using a FD operation based on at least one condition.

Abstract: A method of wireless communication, by a user equipment (UE), includes receiving multiple neural network training configurations for channel state feedback (CSF). Each configuration corresponds to a different neural network framework. The method also includes training each of a group of neural network decoder/encoder pairs in accordance with the received training configurations. A method of wireless communication, by a base station, includes transmitting multiple neural network training configurations to a user equipment (UE) for channel state feedback (CSF). Each configuration corresponds to a different neural network framework. The method also includes receiving a neural network decoder/encoder pair trained in accordance with the training configurations.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) supporting full duplex communications may determine that a set of downlink messages to be transmitted from a base station to the UE overlaps in time with a set of uplink messages to be transmitted from the UE. Accordingly, the UE may determine a downlink transmission power adjustment value for the set of downlink messages. In some examples, the base station may indicate the downlink transmission power adjustment value to the UE via radio resource control (RRC) signaling, a downlink control information (DCI) message, or both. The UE may transmit the set of uplink messages while simultaneously receiving the set of downlink messages with a transmission power that corresponds to the downlink transmission power adjustment value. Adjusting the transmission power for the set of downlink messages may reduce self-interference at the UE, the base station, or both.

Abstract: Aspects presented herein may enhance a HARQ feedback operation to improve data retransmissions by using tri-state HARQ feedback, and may enable a UE to construct a codebook for tri-state HARQ feedback. In one aspect, a UE determines whether tri-state HARQ feedback or bi-state HARQ feedback is configured based on a DL carrier. The UE generates HARQ feedback for at least one of a received PDCCH or a received PDSCH on the DL carrier based on the determination whether the DL carrier is configured with the tri-state HARQ feedback. The UE transmits the generated HARQ feedback.

Abstract: Methods, systems, and devices for wireless communications are described. A configuration for a reference signal used to determine a non-linear behavior of transmission components at a transmitting device may be determined. The configuration for the reference signal may be determined based on signaling transmitted by the transmitting device, signaling transmitted by a device that receives the reference signal, or both. Additionally, or alternatively, the configuration for the reference signal may be determined based on a configuration of other signals transmitted by the transmitting device prior to or concurrently with the transmission of the reference signal. The determined configuration may be used to generate and transmit the reference signal or to determine a configuration of a received reference signal. In both cases, a non-linear response of transmission components at the transmitting device may be determined based on the reference signal.

Abstract: Techniques for indicating system information block or paging waveforms for future communications may include a user equipment (UE) configured to identify a waveform configuration of a downlink (DL) signal including system information to be received from a base station during a random access channel (RACH) procedure in response to an indication of the waveform configuration of the DL signal. The UE may also be configured to receive, from the base station, the system information in response to the waveform configuration of the DL signal being identified.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration of a plurality of bandwidth parts (BWPs) in a frequency band, wherein the configuration identifies a respective BWP-specific downlink (DL)-uplink (UL) pattern for each BWP of the plurality of BWPs, and wherein at least two of BWPs of the plurality of BWPs are configured with different BWP-specific DL-UL patterns and wherein each DL-UL pattern specifies which time intervals of a plurality of time intervals are dedicated to downlink and which time intervals of the plurality of time intervals are dedicated to uplink. The UE may communicate with the base station in one or more active BWPs of the plurality of BWPs using the respective BWP-specific DL-UL pattern for each of the one or more active BWPs. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may transmit configuration information indicating a first precoding matrix indicator (PMI) parameter and a second PMI parameter, wherein the first PMI parameter is associated with non-simultaneous activity of a distributed unit (DU) and a mobile termination (MT), and wherein the second PMI parameter is associated with simultaneous activity of the DU and the MT. The wireless node may perform a communication in accordance with a selected PMI parameter of the first PMI parameter and the second PMI parameter based at least in part on whether the DU and the MT are simultaneously active. Numerous other aspects are described.
