Abstract: A configuration for multiple UEs having the same RA-RNTI to generate RA-RNTI for RACH procedures. The apparatus transmits a random access message. The apparatus receives a RAR during a RAR window in response to the random access message. The RAR window spanning at least two system frames. The apparatus determines one or more RA-RNTIs. Each RA-RNTI may be based, at least in part, on a random access channel occasion and type of random access procedure. The apparatus decodes the RAR based on the one or more RA-RNTIs.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for RLC buffer reduction techniques. A wireless transmitter may generate at least one RLC PDU and at least one RLC parity PDU based on an encoding procedure for an RLC SDU. The wireless transmitter may store, in an RLC buffer, the at least one RLC parity PDU for the RLC SDU and transmit, to a MAC layer, at least one of the segmentation of the RLC SDU or the at least one RLC PDU. A wireless receiver may generate RLC PDU feedback for at least one of the RLC SDU, the segmentation of the RLC SDU, or the at least one RLC PDU and transmit, to an RLC layer, the RLC PDU feedback including an indication of an additional number of encoded RLC PDUs and at least one of an ACK_SN or a NACK_SN.

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.
