Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information indicating whether hybrid automatic repeat request (HARQ) feedback is disabled for one or more HARQ processes. The UE may receive a downlink communication. The downlink communication may include a HARQ process identifier that indicates a HARQ process to be used for the downlink communication. The UE may selectively provide HARQ feedback for the downlink communication based at least in part on the HARQ identifier and information indicating whether HARQ feedback is disabled for the HARQ process. Numerous other aspects are provided.

Abstract: Wireless communication systems and methods related to determining a new multimedia broadcast multicast service (MBMS) configuration for a MBMS that is backward compatible with a legacy MBMS configurations. A base station determines a MBMS configuration. The MBMS configuration includes at least one non-optional field that indicates compatibility with a first user equipment (UE) having a first MBMS capability or compatibility with a second UE having a second MBMS capability. The MBMS configuration also includes a sub-carrier spacing indication for a MBMS corresponding to the first MBMS capability or the second MBMS capability. The MBMS configuration is broadcasted to the first UE and the second UE.

Abstract: Disclosed are techniques for wireless communication using satellite access to a wireless network, where a wireless cell supported by a satellite is moving or temporarily fixed. In an aspect, a radio access network (RAN) entity or a user equipment (UE) provides, to a core network entity, an enhanced cell global identifier (CGI), where the enhanced CGI includes at least one field representing a location of the UE. Based on the enhanced CGI, the core network entity determines a location of the UE, and may provide a service to the UE based on the location. A core network may also provide an enhanced CGI to a RAN, e.g., to support wireless emergency alerting to UEs.

Abstract: A scheduling offset between an uplink and downlink radio frame timing structure of a user equipment (UE) may be updated to provide for more efficient utilization of hybrid automatic repeat request (HARQ) processes in a non-terrestrial network. For instance, different UEs may experience different round trip delays (RTDs) with a non-terrestrial cell. Different UEs may be configured with different scheduling offsets such that scheduling delays may be reduced and HARQ processes identifiers may be reused more rapidly. Additionally or alternatively, wireless communications systems may define one or more separation distances (or timing thresholds) for timing between communications and HARQ processes may be reused based on the separation distance threshold (e.g., such that a satellite may reuse a HARQ process ID for two scheduled communications that have not yet been performed by the UE).

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a control message indicating one or more decryption keys for multicast and broadcast service (MBS) communications within a geographic service area supported by one or more cells of a non-terrestrial network (NTN) or a terrestrial network (TN). The UE may also receive geographic information associated with the geographic coverage area, synchronization information associated with the one or more cells, prioritization information associated with the one or more cells, or a combination thereof. Accordingly, the UE may receive an MBS message via the one or more cells, and may decrypt the MBS message based on the control message, the geographic information, the synchronization information, the prioritization information, or a combination thereof. The techniques described herein may enable the UE to receive encrypted MBS communications within the geographic service area.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network entity may establish a first user equipment (UE) identifier (ID) associated with pre-paging. The first network entity may transmit, with information associated with the first UE ID, a request associated with paging to a second network entity. Numerous other aspects are described.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus may communicate with a user equipment (UE) during an active state of the UE in accordance with a first UE configuration. The apparatus may perform, associated with a second network node and based on a determination to switch the UE to an inactive state, an access stratum (AS) context relocation operation and a path switch operation associated with the second network node. Numerous other aspects are described.

Abstract: A wireless device may output a first message or a compression context message. The first message may include (a) a first payload associated with a first RTP-SN, (b) the first RTP SN, and (c) a first PDCP SN that is incrementally synchronized with the first RTP SN. The compression context message may include an indicator of compression context between the first RTP SN and the first PDCP SN. The wireless device may obtain a confirmation that a compression context between the first RTP SN and the first PDCP SN is established at a receiver. In response, the wireless device may output a second message. The second message may have a second payload associated with a second RTP SN and a second PDCP SN that is incrementally synchronized with the second RTP SN. The second message does not comprise a ROHC header having an RTP SN field.
