Abstract: Wireless communications systems may support flexible waveform configuration for autonomous uplink transmissions. A base station may transmit broadcast signaling (e.g., a system information block (SIB)) indicating waveform configuration information for an autonomous uplink transmission by a user equipment (UE). In some cases, the broadcast signaling may include a waveform configuration field (WCF) that may indicate whether flexible waveforms for autonomous uplink are supported, may configure a waveform type, may indicate waveform configuration mapping rules, etc. As such, a UE may identify whether flexible waveform configuration for autonomous uplink is supported, and may determine waveform types for autonomous uplink transmissions based on waveform type configuration information from a base station (e.g., which may include an indication of whether flexible waveform configuration is supported, an indication of waveform type/scenario mapping rules, etc.), one or more LUTs, identified autonomous uplink scenarios, autonomous uplink transmission parameters, or some combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a beam failure at a first transmission-reception point (TRP) associated with a serving cell. The UE may transmit, to a base station via a second TRP, a scheduling request (SR) for a beam failure recovery (BFR) via a first SR physical uplink control channel (PUCCH) resource. The UE may detect a beam failure at a second TRP associated with the serving cell or another serving cell. The UE may transmit, to the base station, the SR via a second SR PUCCH resource with a spatial relation configured for the SR. Numerous other aspects are described.

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, configuration information indicating that network coding is enabled for initial transmissions associated with a multicast/broadcast service (MBS) and indicating that network coding is enabled for retransmissions associated with the MBS. The UE may receive, via a multicast traffic channel or a dedicated traffic channel, an initial transmission associated with the MBS, wherein the initial transmission is associated with a first set of encoded packets. The UE may transmit a radio link control (RLC) status feedback message associated with the initial transmission. The UE may receive, via the multicast traffic channel or the dedicated traffic channel, a retransmission associated with the initial transmission, wherein the retransmission is associated with a second set of encoded packets. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit configuration signaling such as radio resource control (RRC) signaling to a user equipment (UE) which indicates a number of sounding reference signal (SRS) resource sets and respective SRS resources within each of the SRS resource sets that may be used for channel estimation. The base station may subsequently transmit a control message such as a medium access control (MAC) control element (CE) to the UE, which indicates an activation status for at least one SRS resource within the SRS resource set. Basedon the indicated activation status for the at least one SRS resource, the UE may transmit one or more SRSs to the base station.

Abstract: Devices and techniques for wireless communications are described. A user equipment (UE) may receive, broadcasted from a base station, a system information block (SIB) including access control information (e.g., unified access control (UAC) barring information) for communications over an air-to-ground (ATG) network. In some examples, the UE may identify the UAC barring information in an information element (IE) in the SIB, in one or more IEs of a barring IE in the SIB, based on one or more access identities, based on one or more access categories, or any combination thereof. The UE may transmit, to the base station, signaling indicating an access request to the ATG network based on the receiving of the SIB, identifying the UAC barring information, or both. The UE may communicate with the base station over the ATG network based on the transmitting of the signaling.

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 beam failure detection (BED) reference signal set in one or more slots in a full-duplex mode and in one or more slots in a half-duplex mode. The UE may detect beam failure due to self-interference based at least in part on a comparison of measurements of the BFD reference signal set in the full-duplex mode and half-duplex mode. The UE may switch from the full-duplex mode to the half-duplex mode for slots configured for the full-duplex mode based at least in part on detecting beam failure due to self-interference. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a wireless device may In use non-uniformly distributed bits for amplitude mapping and uniformly distributed bits for sign mapping to support probabilistic constellation shaping (PCS) for transmission of a message. To provide a coding gain with one or more retransmissions of the message, the device may configure redundancy versions based on the non-uniform distribution of one or more symbols. In some examples, the device may include the same set of non-uniformly distributed systematic bits or at least a portion of non-uniformly distributed systematic bits in each redundancy version of the message. Additionally or alternatively, the device may use multiple modulation and coding scheme (MCS) values to modulate one or more of the redundancy versions, where a first MCS value is used to modulate non-uniformly distributed symbols and a second MCS value is used to modulate uniformly distributed symbols.

Abstract: Certain aspects of the present disclosure provide techniques for systems and methods for detecting trigger conditions for panel specific power reporting. For example, a user equipment (UE) may detect that a trigger condition for panel specific power reporting is met, where the trigger condition involves at least one metric for at least one of multiple antenna panels of the UE. Further, the UE may transmit a report with power-related information specific for at least one of the antenna panels in response to detecting the trigger condition.
