Abstract: Aspects of the present disclosure provide systems and methods for informing a user equipment (UE) that which beam the UE is being served, for example, such as in relation to bandwidth part (BWP) switching in a non-terrestrial network (NTN). According to certain aspects, a network entity may transmit to a user equipment (UE) signaling indicating at least one BWP switch. The network entity provides, to the UE, an indication of a serving synchronization signal block (SSB) for the UE to use after the BWP switch.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a neighbor cell list that indicates at least one neighbor cell. The UE may perform a cell selection procedure or a cell reselection procedure to switch to a serving cell without receiving an updated neighbor cell list from the serving cell. Numerous other aspects are provided.

Abstract: A UE may receive, from at least one cell via at least one bit in a MIB or a SIB, a barring indication based on a supported network of the at least one cell and a supported network of the UE. The supported network of the at least one cell may correspond to a TN or an NTN, and the supported network of the UE may correspond to a TN or an NTN. The UE may skip, based on the received barring indication, a selection of the at least one cell for communication. Accordingly, the UE may not camp on the at least one cell. The barring indication for NTN-supporting UEs and for TN-supporting UEs may be separately indicated via the MIB or the SIB.

Abstract: Aspects relate to mechanisms for wireless communication devices to update satellite and beam specific information. A user equipment (UE) selects a first cell associated with a first satellite for wireless communication in the non-terrestrial network. The UE determines whether to use one or more standard parameters or one or more satellite-cell specific parameters for accessing the first cell. The one or more standard parameters are based on one or more standard characteristics common to a plurality of satellites including the first satellite. The one or more satellite-cell specific parameters are based on a change to at least one standard characteristic of the one or more standard characteristics of the first satellite.

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: 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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a network may establish communications over a directional beam. The UE may receive, from the network, a configuration of one or more channel sounding messages for one or more directional beams, where each directional beam of the one or more directional beams is associated with a set of narrowband carriers, and each of the one or more channel sounding messages being configured for transmission on a narrowband carrier of the set of narrowband carriers. The UE may determine a trigger for transmitting the one or more channel sounding messaged based at least in part on the configuration and transmit, to the network, the one or more channel sounding messages on respective narrowband carriers in accordance with the trigger and the configuration.

Abstract: Wireless communications systems and methods related to coverage-level-based paging carrier selection are provided. In some aspects, a method of wireless communication performed by a user equipment includes receiving, from a base station, a first indication of one or more paging carriers, the first indication indicating for a paging carrier of the one or more paging carriers, a coverage level supported by the paging carrier; and receiving, from the base station, a paging message via the paging carrier based on a match between the coverage level supported by the paging carrier and a coverage level of the user equipment.

Abstract: Methods, systems, and devices for wireless communications are described. A serving base station or a serving satellite may transmit a timing configuration to the UE based on a reference unit, such as a location at a beam center for a respective satellite, a threshold distance relative to the beam center for the respective satellite, a reference time, or any combination thereof. In some cases, the UE may monitor for one or more SSBs from the neighboring satellites according to the timing configuration and a respective propagation delay between the UE and each of the neighboring satellites. The UE may measure the SSBs according to the measurement gap and measurement window in the timing configuration. In some examples, the UE may perform a cell handover procedure or a cell reselection procedure based on measuring the SSBs.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a message from a first non-terrestrial network cell indicating cell synchronization information for a second non-terrestrial network cell. In some examples, the cell synchronization information may indicate whether the first non-terrestrial network cell and the second non-terrestrial network cell are synchronized at a reference point. Additionally, or alternatively, the cell synchronization information may indicate a timing offset value between a first uplink time synchronization reference point of the first non-terrestrial network cell and a second uplink time synchronization reference point of the second non-terrestrial network cell. The UE may calculate a timing associated with signaling from the second non-terrestrial network cell based at least in part on the cell synchronization information. The UE may receive one or more signals from the second non-terrestrial network cell based at least in part on the calculated timing.
