Abstract: A UE may include IoT NTN device, and the UE may acquire the GNSS location to perform the time/frequency pre-compensation. A NAS layer of the UE may initiate a connection request procedure based on the GNSS fix procedure at one or more lower layer of the UE. A network may transmit a paging request to the UE, and manage a paging response timer based on the GNSS fix procedure at the UE.

Abstract: A method for wireless communication includes validating a PUR configuration in a NTN based on location-related information associated with a satellite. For example, a UE may determine, based on location-related information of a satellite in a non-terrestrial network, whether a preconfigured uplink resource (PUR) configuration is valid. The UE may also transmit, to a base station (BS) via the satellite in response to determining that the PUR configuration is valid, a communication signal in a PUR. For example, the UE may determine, based on the location-related information associated with the satellite, if the parameter satisfies the threshold, and transmit UL data in a PUR occasion based on the determined parameter satisfying the threshold.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may start a timer after a repetition of a communication, where calculation of a length of the timer includes an offset that corresponds to a propagation delay between the UE and a base station via a non-terrestrial network (NTN) entity. The UE may start a discontinuous reception (DRX) retransmission timer after expiration of the timer. Numerous other aspects are described.

Abstract: A user equipment may be configured to perform cell reselection during a gateway and/or satellite switch. In some aspects, the user equipment may select a current cell of a satellite device in a radio access network (RAN) and receive, from the satellite device, cell reselection information for identifying a destination cell for selection in response to a link modification. Further, the user equipment may select, via a cell reselection process, the destination cell based on the cell reselection information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine a polarization of a bandwidth part. The base station may transmit, to a user equipment, a polarization indication that indicates the polarization for the bandwidth part. Numerous other aspects are provided.

Abstract: In a communication between a user equipment (UE) and a network node, the UE may receive a grant of uplink (UL) shared channel (SCH) resources from the network node. Each of the UL SCH resources may be associated with one of a plurality of hybrid automatic repeat request (HARQ) processes. Each HARQ process may be at least one of a plurality of HARQ process types, and each HARQ process type may be based on HARQ feedback status and HARQ retransmission status. The UE may transmit a control message on one or more UL SCH resources in response to the one or more UL SCH resources being determined to be usable based on the HARQ process type of the HARQ processes associated with the one or more of the UL SCH resources.

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: A base station may transmit a broadcast/multicast service in a multicast broadcast single frequency network (MBSFN) area multicast communication. A method of wireless communication at a base station in accordance with an aspect of the present disclosure comprises determining a broadcast/multicast service to be provided to a user equipment (UE) in a multicast broadcast single frequency network (MBSFN) area, and transmitting a tracking reference signal (TRS) to the UE, the TRS indicating information associated with receiving the broadcast/multicast service by the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a multicast channel configuration that indicates a set of multicast channel time domain resources allocated to a multicast channel for a first multicast broadcast area. The UE may receive an indication of a first set of time domain resources, of the set of multicast channel time domain resources, that have a first reference signal pattern that differs in frequency domain density as compared to a second reference signal pattern used for at least one of a second set of time domain resources of the set of multicast channel time domain resources or a second multicast broadcast area. The UE may decode the first set of time domain resources based at least in part on the first reference signal pattern. Numerous other aspects are provided.

Abstract: A base station maps code blocks of a transport block of a transport block size (TBS) for a channel using tone-level interleaving or resource element (RE)-level interleaving. Then, the base station can transmit the code blocks of the transport block of the TBS for the channel. A UE may receive the channel from the base station and de-interleave the received tones of the channel in a frequency domain to obtain the code blocks of the transport block having the TBS for the channel.
