Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving a first message comprising a configuration for reconstructing a bandwidth part (BWP) for a network entity. The BWP may be used on a non-terrestrial beam of a non-terrestrial entity. The method also includes reconstructing a BWP of the BWPs based on the configuration. The method further includes switching from a current BWP to the reconstructed BWP to communicate with the network entity, e.g., non-terrestrial entity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for wake up signals (WUSs) from a network entity (e.g., satellite) of a non-terrestrial network based on a geographic area. For example, the UE may monitor for WUSs if the UE is within a geographic area. In other examples, a UE may monitor for WUSs according to an assigned location-based WUS group if a cell supports the WUS group. In some cases, a network entity or UE may select a WUS resource set based on a location parameter. In some cases, a network entity or UE may select a WUS group based on a location parameter. In some cases, one or more network entities may determine geographic areas where the network may use WUSs or WUS groups, or the one or more network entities may negotiate with the UE to determine such areas.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support non-terrestrial network (NTN) signaling between both terrestrial and non-terrestrial devices. A user equipment (UE) supporting such NTN signaling may receive a downlink message indicating a first configuration for a first transmission reception point corresponding to a first cell of the NTN, and a second configuration for a second transmission reception point corresponding to a second cell of the NTN. The UE may then perform one or more synchronization measurements to synchronize uplink communications with the first transmission reception point and the second transmission reception point and in order to perform multi-transmission reception point communications in the NTN. The UE may then transmit one or more uplink messages to the first transmission reception point, to the second transmission reception point, or both, in accordance with the one or more synchronization measurements.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, while operating using a first beam corresponding to a cell, a second beam corresponding to the cell based at least in part on a set of beam information associated with the second beam, wherein a first narrowband is associated with the first beam and a second narrowband is associated with the second beam. The UE may communicate with a wireless communication device that provides the cell using the second beam. Numerous other aspects are provided.

Abstract: A method for wireless communication performed by a user equipment (UE) identifies multiple cell global identities (CGIs) broadcast by a cell. The method also determines a current tracking area identity of the UE from multiple tracking area identities of the cell based on a rule. The rule may be based on a preconfigured or predefined rule. The method selects a first CGI of the CGIs based on the determined tracking area identity.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity (e.g., a satellite) may receive control signaling indicating a discontinuous service coverage at a user equipment (UE). The network entity may transmit coverage assistance information indicating a discontinuous service coverage pattern to the UE. The UE, the network entity, or both may determine one or more parameters for a power saving mode at the UE, such as a duration of an active time, a duration of an inactive time, a duration of a keep alive time, or a combination thereof based on the coverage assistance information. In some cases, the UE may transmit an indication of the power saving mode parameters to the network entity. The network entity may transmit a control message to the UE in accordance with the parameters.
