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 method of wireless communication performs a public land mobile network (PLMN) search for a higher priority PLMN. The PLMN search includes a candidate PLMN having a different mobile country code (MCC) than a serving PLMN. The method switches to the higher priority PLMN when the PLMN search locates the higher priority PLMN. A method determines whether a user equipment (UE) has transitioned between an international area and a national area. The method triggers PLMN selection in response to the UE having transitioned between the international area and the national area.

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: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for enabled/disabled HARQ feedback and HARQ-less processes. A base station may configure a plurality of logical channels for a UE, where one or more of the logical channels have an associated HARQ process. The UE may receive an allocation of resources from the base station for an uplink grant or a downlink assignment and determine whether the resources have associated HARQ process without HARQ feedback but with HARQ retransmission, an associated HARQ process without HARQ feedback and without HARQ retransmission, or an associated HARQ process with HARQ feedback and with HARQ retransmission. The UE may exchange communication with the base station based on the allocation of resources and the determination of whether the resources have one of the associated HARQ processes.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, to a base station associated with a non-terrestrial network and in connection with a random access procedure, a message that indicates a location of the user equipment; and receive a response to the message that indicates whether the message is accepted or rejected, the response being based at least in part on the location. Numerous other aspects are provided.

Abstract: A base-station (BS) receiving a random access request from user equipment (a UE), followed by a connection request. The connection request contains UE identity information which may have one of multiple formats depending on whether the access request and/or the connection request indicate that the UE is operating as a bandwidth-limited (BL) UE, an enhanced coverage (CE) UE, or a UE that operates in neither the BL mode nor the CE mode. In the BL mode, the UE may transmit a truncated identifier that is sufficient for the BS to retrieve capability information for the UE prior to transmitting a resource grant to the UE. The BS may then configure the UE and BS to using a radio configuration optimized for the UE's capabilities and transmit the resource grant in accordance with the optimized configuration.

Abstract: A method of wireless communication by a user equipment (UE) calculates a propagation delay for sending a message from the UE to a network node, such as a base station, via non-terrestrial communications. The method sends a random access preamble to the base station while accounting for the calculated propagation delay. The method starts a random access response (RAR) window at a first physical downlink control channel (PDCCH) occasion after twice the calculated propagation delay from sending the random access preamble. The method receives a random access response (RAR) message from the base station during the RAR window. The RAR message includes an uplink grant indicating an uplink shared channel resource. Further, the method sends an uplink message to arrive during the uplink shared channel resource while accounting for the calculated propagation delay.
