Abstract: A user equipment (UE) selects or reselects a target cell of a non-terrestrial network or resumes connectivity with the target cell after a satellite handover for a permanently fixed low Earth orbit (LEO) cell. The target cell is a serving or non-serving cell. The UE determines a cell type of the target cell. The cell type may be a LEO cell type, a geostationary Earth orbit (GEO) cell type, a moving cell type, a fixed cell type, a temporarily fixed LEO cell type, or a permanently fixed LEO cell type. The UE completes selection or reselection of the target cell or completes the connectivity with the target cell, based on the cell type.

Abstract: A method for wireless communication at a user equipment (UE) includes receiving, from a base station, multicast data via a multicast channel. The method also includes transmitting, to the base station, multicast feedback based on receiving the multicast data. In some examples, the multicast feedback is associated with a group of UEs including the UE. The method further includes receiving, from the base station, a re-transmission of the multicast data on the multicast channel or a unicast channel based on one or more of a number of UEs served by the base station, a number of UEs from the group of UEs providing the multicast feedback, or a radio channel condition.

Abstract: Apparatus, methods, and computer-readable media for facilitating using of pre-configured UL resources to transmit grant-free data or reference signals are disclosed herein. An example method for wireless communication by a UE includes transmitting, to a base station, a capability of the UE to transmit data in a first message of a random access procedure. The example method also includes receiving pre-configured UL resources from the base station. The example method also includes transmitting data in the first message of the random access procedure using the pre-configured UL resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an offset associated with a propagation delay in a network, wherein hybrid automatic repeat request (HARQ) feedback is enabled at the UE, and may monitor for a retransmission of a downlink communication in the network according to the offset. In some aspects, a UE may start a timer associated with monitoring for a retransmission of a downlink communication in a network, wherein HARQ feedback is disabled at the UE, and may monitoring for the retransmission of the downlink communication after starting the timer or after expiration of the timer. Numerous other aspects are provided.

Abstract: Aspects described herein relate to indicating downlink control information (DCI) for multicast and/or broadcast (MB) communications using DCI formats that may be based on existing DCI formats and/or size for unicast communications, paging signals, system information signals, etc., or may include shortened formats without fields for information that may not be used in MB communications.

Abstract: Some techniques and apparatuses described herein enable a user equipment (UE) to autonomously modify one or more transmission parameters, other than a transmit power, for uplink communications after detecting a change in pathloss. The UE may modify the one or more transmission parameters without receiving instructions from a base station, such as in downlink control information, with updated value(s) for the one or more transmission parameters. As a result, the UE and the base station avoid the round trip delay that would otherwise be required to modify the transmission parameter(s) and perform link adaptation. Some techniques and apparatuses described herein apply to non-terrestrial networks with a large round trip delay. 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 radio bearer (MRB) in a radio link control (RLC) acknowledged mode; enter an idle state or an inactive state after the MRB has been configured; and maintain the MRB while the UE is in the idle state or the inactive state subject to one or more limitations associated with maintaining the MRB in the idle state or the inactive state. 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 hybrid automatic repeat request (HARQ) process identifier for a communication between the UE and a base station using a semi-persistent scheduling (SPS) configuration or a configured grant (CG) configuration, wherein the determination of the HARQ process identifier is based at least in part on an offset applied for the determination of the HARQ process identifier; and perform the communication based at least in part on the HARQ process identifier. Numerous other aspects are provided.

Abstract: Techniques and apparatuses described herein provide for an indication that a unified access control (UAC) parameter of a user equipment (UE) has changed. For example, a paging message or direct indication information may be provided to a UE indicating that a UAC parameter has changed. In such a case, the UE may not be expected to periodically check a scheduling information list of a system information block type 1 (SIB1). Thus, battery power of UEs may be conserved and signaling resources that would otherwise be used to periodically check the scheduling information list may be conserved.
