Abstract: This disclosure provides systems, methods and apparatuses for using acknowledgement or negative acknowledgement (ACK-NACK) bundling when reporting from a user equipment (UE) a bundled ACK-NACK for a plurality of physical downlink shared channels (PDSCHs) associated with a PDSCH grant. A counter downlink assignment indicator (DAT) and a total DAI may be used to track PDSCH grants that are received at the UE. The UE may detect missing PDSCHs and report ACK-NACKs for the missing PDSCHs based on the counter DAI and the total DAI. A base station (BS) may transmit the PDSCH grant associated with the plurality of PDSCHs to the UE. The BS may receive, from the UE, the bundled ACK-NACK for the plurality of PDSCHs associated with the PDSCH grant.

Abstract: Aspects described herein relate to providing demodulation reference signal (DMRS) transmissions for channel transmission repetitions. This can include defining DMRS patterns for channel transmission repetitions having a symbol length that is less than a threshold, dropping or deferring channel transmission repetitions that are mapped to a set of uplink symbols that are less than a threshold symbol length, and/or the like.

Abstract: In an aspect, a first UE transmits SL-PRS to a second UE based on a bandwidth associated with DL-PRS(s) from one or more gNBs to the second UE in association with a positioning procedure of the second UE. In other aspects, a network component (e.g., LMF UE, etc.) triggers transmission of a WLAN ranging signal from a first UE to a second UE (e.g., to supplement an NR-based positioning procedure).

Abstract: According to embodiments herein, a UE can be configured with a spatial relationship for an Uplink Position Reference Signal (UL-PRS) to transmit via the SL interface. This information can include various options related to a transparent mode in which an anchor UE connected with the UE via the SL interface generally acts like a base station. In an advanced mode, any of a variety of aspects of the SL interface used in communication between the UE and anchor UE may be used as a reference for UL-PRS.

Abstract: The apparatus of wireless communication may be a UE configured to activate a MAC-CE transmitted over an SL relay after waiting a time period by receiving an activation request for a command in association with a third UE in a first MAC-CE relayed from a second UE, transmitting, to the second UE, a second MAC-CE including an activation response to the third UE in response to the activation request, and activating the command after transmitting the activation response. The UE may wait a time period after transmitting the activation response before activating the command. The UE may receive an HARQ ACK from the third UE in response to the transmitted activation response or an HARQ ACK from the second UE in response to the transmitted activation response, and wait a time period after receiving the HARQ ACK before activating the command.

Abstract: Embodiments include systems and methods for UE signaling a network regarding customized ringing signal (CRS) capability and use of such information by the network. Various embodiments may receiving from the network an INVITE message notifying the UE of an incoming call, determining whether the INVITE message indicates that the network provides CRS service if the UE supports a CRS function, and including an indication in a response to the INVITE that the UE supports the CRS function in response to determining that the INVITE message includes an alert information header field indicating that the network provides CRS service. Various embodiments include a network computing device receiving such information and performing negotiations for CRS service with the UE only if the UE indicates CRS functional capability.

Abstract: Disclosed are techniques for environment sensing. In an aspect, a transmitter base station determines a configuration for a radio frequency (RF) sensing signal, the configuration determined based at least in part on coordination among a plurality of base stations, and transmits the RF sensing signal to at least one receiver base station based on the configuration. In an aspect, a receiver base station receives a configuration for an RF sensing signal, the configuration determined based at least in part on coordination among a plurality of base stations, receives, from at least one transmitter base station, the RF sensing signal, and detects at least one target object based, at least in part, on reception of the RF sensing signal.

Abstract: Aspects relate to configuration of a single sounding reference signal (SRS) resource set for a UE that includes SRS resources associated with multiple, different transmission and reception points (TRPs). A radio access network (RAN) entity, which may be associated with one or more of the TRPs, may configure an SRS configuration for the SRS resource set and transmit the SRS configuration to the UE. The UE may then transmit a plurality of SRS(s) to the multiple TRPs in accordance with the SRS configuration. Other aspects, features, and examples are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, an indication of a time gap value associated with a random access channel (RACH) procedure, wherein the time gap value is based at least in part on a capability of the base station, determine whether a physical RACH (PRACH) occasion associated with the RACH procedure is valid based at least in part on receiving the indication of the time gap value associated with the RACH procedure, and selectively transmit, to the base station, a PRACH transmission in the PRACH occasion based at least in part on determining whether the PRACH occasion is valid. Numerous other aspects are provided.

Abstract: A method of wireless communication by a first sidelink UE measures multiple reference signals periodically transmitted by a second sidelink UE using multiple receive beams corresponding to reference signals in response to a beam failure declared by the first UE. The method also selects one of the reference signals that satisfies a condition. The method further includes notifying the second sidelink UE of the selected reference signal using a beam corresponding to the selected reference signal. Another method of wireless communications by a first sidelink UE includes periodically transmitting, to a second sidelink UE, multiple beam failure recovery (BFR) reference signals across multiple transmit beams. The method also includes receiving, from the second sidelink UE, an indication of a selected beam for communications between the first sidelink UE and the second sidelink UE. The method notifies the second sidelink UE of successful beam failure recovery.
