Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a reference signal received power (RSRP) associated with a reference signal (RS) broadcast by a network. The UE may further measure a received signal strength indicator (RSSI) using a plurality of resource elements (REs) that do not include the RS and excluding REs that do include the RS. Accordingly, the UE may determine a reference signal received quality (RSRQ) associated with the RS based at least in part on the RSRP and the RSSI. 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 determine a duration of a first gap that precedes a reference signal, based at least in part on a polarization of the reference signal. The UE may determine a duration of a second gap that succeeds the reference signal, based at least in part on the polarization of the reference signal. The UE may perform a measurement of the reference signal based at least in part on the first gap and the second gap. Numerous other aspects are provided.

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: 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.
