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.

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, configuration information associated with a semi-static hybrid automatic repeat request (HARQ) feedback codebook for multicast messages. The UE may receive, from the network entity, a physical downlink control channel (PDCCH) message, associated with a radio network temporary identifier (RNTI), scheduling one or more multicast physical downlink shared channel (PDSCH) messages. The UE may transmit, to the network entity, one or more fallback HARQ feedback indications, associated with the one or more multicast PDSCH messages, in lieu of transmitting the semi-static HARQ feedback codebook, in accordance with the configuration information and associated with at least one of the RNTI or a feedback configuration associated with the RNTI. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described Generally, the described techniques provide for a user equipment (UE) to perform a beam switching operation from a current beam to a target beam based on a beam switching duration. The UE may transmit a capability report that may include an antenna pointing capability, a list of one or more detailed capabilities, or both to another device, such as a network entity (e.g., a satellite). The UE may perform the beam switching operation based on the capability report. The UE may perform a random access procedure as part of a change of association operation. The UE may receive a control message from the other device, which may be the network entity, that includes an identity of a target network entity, one or more resources for the random access procedure, an indication of the beam switching duration, or any combination.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine resource selection priority levels associated with available resources for sidelink signaling in an unlicensed radio frequency spectrum band, the resources selection priority levels may be determined based on resource reservation information of the available resources, a time domain location of the available resources, or both. For example, a first resource of the available resources may be associated with a higher priority than a second resource of the available resources in resource selection. The UE may select one or more resources for the sidelink signaling from the available resources based on the resource selection priority levels associated with the available resources. The UE may transmit the sidelink signaling on the unlicensed radio frequency spectrum band using the one or more selected resources.

Abstract: Aspects of the present disclosure provide techniques configuring half duplex UEs (HD-UEs) to implement supplementary downlink (SDL) in band combination that may be in same or different frequency range designations (e.g., FR1 or FR2). Particularly, in order to compensate for the loss of downlink coverage and improve load balancing, aspects of the present disclosure configure the UE to perform random-access channel (RACH), a procedure that is a shared channel used by wireless terminals to access the mobile network, on the anchor carrier in time division duplex (TDD) band and after initial access, the UE may be configured to switch to SDL to receive subsequent downlink signals.

Abstract: Certain aspects of the present disclosure provide techniques for unlicensed channel occupancy time sharing based on received signal strength. A method that may be performed by a first user equipment (UE) includes receiving a first transmission from a second UE, the first transmission indicating the second UE has acquired a frequency band for a channel occupancy time (COT). The method may also include transmitting a signal within the frequency band during the COT in response to a signal strength of the first transmission as received by the first UE being greater than at least one threshold.
