Abstract: Certain aspects are directed to a user equipment (UE) configured to receive reference signals from a network node via multiple resource element groups (REGs) including at least one REG carrying a downlink transmission. In some examples, the UE may be configured to receive, from the network node, communication parameters for a downlink transmission, the communication parameters indicative of a first resource element group (REG) bundle and a second REG bundle. In some examples, the UE may receive the downlink transmission via the first REG bundle. In some examples, the UE may be configured to perform channel estimation of the downlink transmission based on reference signals transmitted via the first REG bundle and the second REG bundle.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus at a UE in NTN are provided. The UE may be configured to receive one or more FPC commands from an NTN. The UE may be further configured to transmit, in response to receiving the one or more FPC commands, an uplink transmission with a frequency change having a total FPC adjustment calculated based on (a) a current UE location update and a current UE velocity update, wherein the total FPC adjustment satisfies one or more threshold requirements, or (b) an intermediary UE location update between the current UE location update and a previous UE location update and an intermediary UE velocity update between the current UE velocity update and a previous UE velocity update.

Abstract: Group common Downlink Control Information (DCI) for Aperiodic Positioning Reference Signal (AP-PRS) triggering is described herein. Embodiments for such AP-PRS may include AP-PRS triggering commands and/or positioning measurement request commands, and may be mapped to one or more bits of different blocks of the group common DCI to identify different aspects of the AP-PRS, such as one or more Positioning Frequency Layers (PFLs), PRS identifiers (PRS-IDs), PRS resource sets, and/or PRS resources.

Abstract: Wireless communications systems and methods related to multiplexing a sidelink-synchronization signal block (S-SSB) transmission with a physical sidelink control channel (PSCCH)/physical sidelink shared channel (PSSCH) transmission for occupancy channel bandwidth (OCB) fulfilment are provided. A user equipment (UE) determines a multiplex configuration for multiplexing a sidelink transmission with a S-SSB transmission in a sidelink bandwidth part (BWP). The UE communicates, in the sidelink BWP during a sidelink slot, the S-SSB transmission and the sidelink transmission are communicated by multiplexing the sidelink transmission and the S-SSB transmission based on the multiplex configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a configuration of at least one sounding reference signal (SRS) resource, wherein the configuration indicates a pseudo-random sequence for muting an SRS associated with the at least one SRS resource. The UE may transmit the SRS using the at least one SRS resource based at least in part on the pseudo-random sequence. Numerous other aspects are described.

Abstract: Aspects described herein relate to indicating search spaces and/or control information formats for receiving multicast/broadcast service (MBS) downlink control information (DCI). A device can receive a search space configuration defining one or more search spaces for detecting communications intended for a group of one or more user equipment (UEs), determine a priority for detecting control information transmitted over a control channel based on the one or more search spaces, and perform, based on the priority, detection for the control information over the control channel based on the one or more search spaces and/or the other defined search spaces.

Abstract: Certain aspects of the present disclosure provide techniques for communicating using sidelink resources allocated in an unlicensed spectrum. A method that may be performed by a first UE includes establishing a connection with a second UE for sidelink communication in an unlicensed spectrum and communicating with the second UE via the connection using one or more sidelink sub-channels in the unlicensed spectrum according to a mapping between sidelink sub-channels and resource block (RB) sets of the unlicensed spectrum, wherein the unlicensed spectrum comprises a plurality of RB sets and one or more guard bands disposed between RB sets in the plurality RB sets.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus at a user equipment (UE) in a non-terrestrial network (NTN) are provided. The UE may be configured to receive one or more timing advance (TA) commands from an NTN. In response to a transmission timing error between a transmission TA of the UE and a reference timing exceeding a threshold, the UE may be configured to transmit an uplink transmission with a timing change having a total timing adjustment, other than a propagation delay adjustment due to an NTN node position update and a network-controlled common TA value, that satisfies one or more threshold requirements.
