Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio access network (RAN) node may transmit, to an access and mobility function (AMF) of a core network, a request associated with a location-based state of a user equipment (UE) served by the RAN node. For example, the location-based state of the UE may be associated with whether the UE is flying or whether the UE is driving. Accordingly, the RAN node may receive a message in response to the request. The RAN node may receive the message in response to the request from the AMF. Alternatively, the AMF may establish a connection between the RAN node and a location management function (LMF) of the core network such that the RAN node receives the message in response to the request from the LMF. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration, for a multicast broadcast service (MBS) single frequency network (SFN) area, indicating configuration information for one or more multicast traffic channels. The UE may receive, in accordance with the configuration, a physical downlink control channel (PDCCH) communication scheduling an MBS SFN data communication associated with a multicast traffic channel, of the one or more multicast traffic channels. The UE may receive the MBS SFN data communication via a physical downlink shared channel (PDSCH) that is associated with both SFN communications and unicast communications or that is associated with only MBS SFN communications. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for random access channel communications in non-terrestrial networks. A method that may be performed by a user equipment (UE) includes transmitting a physical random access channel (PRACH) preamble to the network entity in a random access (RA) occasion; and monitoring for a random access response (RAR) within a RAR window with a start position determined based at least in part on the RA occasion, round trip time parameters for non-terrestrial network communications, and one or more timing offset parameters.

Abstract: Certain aspects of the present disclosure provide techniques for data collection for non-terrestrial networks (NTN). One aspect provides a method for wireless communications by a user equipment (UE). The method generally includes transmitting an indication of a capability of the UE to connect to a network via both terrestrial network (TN) cells and non-terrestrial network (NTN) cells and transmitting one or more data collection reports in accordance with the indicated capability.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from an entity of a non-terrestrial network (NTN), a system information block (SIB) that indicates information relating to one or more NTN SIBs that are to include at least one of ephemeris information or feeder link timing advance information. The UE may receive, from the entity of the NTN, the one or more NTN SIBs based at least in part on the information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that indicates whether a common search space (CSS) is associated with a first type of physical downlink control channel (PDCCH) or a second type of PDCCH. The first type of PDCCH may correspond to a cell-broadcast PDCCH and the second type of PDCCH may correspond to a UE-specific PDCCH. The CSS may be for downlink control information (DCI) with a cyclic redundancy check scrambled by a group radio network temporary identifier (G-RNTI) that schedules a multicast and broadcast service (MBS). The UE may receive, from the base station, the first type of PDCCH or the second type of PDCCH. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A group of random access channel opportunities are identified over which to transmit a preamble associated with a random access channel procedure. A preamble sequence group associated with the identified group of random access channel opportunities is determined based on a repetition level associated with the preamble sequence group. At least one downlink message associated with the random access channel procedure is received based on the repetition level.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a reference time for updating one or more system information parameters associated with a non-terrestrial network (NTN) or updating a cell status associated with the NTN. The UE may determine an update timer length for updating the one or more system information parameters associated with the NTN or the cell status associated with the NTN. The UE may acquire, from a current cell or a new cell, a system information block (SIB) to refresh the one or more system information parameters after an expiration time associated with the one or more system information parameters, wherein the expiration time is based at least in part on the reference time and the update timer length. Numerous other aspects are described.
