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.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain, via broadcast signaling or UE-specific signaling, an indication of an uplink communications configuration for one or more uplink wireless communications that span a set of one or more transmission time intervals (TTIs). The indication may be based on one or more types of the one or more uplink wireless communications. The UE may determine a duration of time for which an uplink pre-compensation is to be applied to the one or more uplink wireless communications. The duration of time may be based on one or more parameters of the uplink communications configuration. The UE may output the one or more uplink wireless communications within the duration of time with the uplink pre-compensation applied.

Abstract: Methods, apparatuses, and computer readable medium for enabling an efficient group handover mechanism that has less signaling overhead than single UE handover are provided. An example method at a base station includes transmitting a group handover request for the group of UEs to a target base station. The method further includes receiving a group handover acknowledgment from the target base station. The method further includes transmitting a group handover message to the group of UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, radio resource control (RRC) signaling indicating a number of padding bits in multicast downlink control information (DCI). The UE may receive, from the base station, a multicast DCI message that includes a set of fields to indicate a set of communication parameters. The UE may interpret the multicast DCI message that indicates the set of communication parameters based at least in part on the number of padding bits indicated by the RRC signaling. 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 receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.

Abstract: Improvements are provided to the paging process for an eMTC UE by allowing a base station and the UE to apply a UE-specific DRX cycle for paging, from one set of DRX cycles, when the UE is operating in non-CE mode and apply another UE-specific DRX cycle, from a more restricted set of UE-specific DRX cycles, when the UE is operating in a CE mode. A UE may report and apply certain UE-specific DRX cycles under non-CE mode, and may change a UE-specific DRX cycle to one from a more restricted set when operating in CE mode. Similarly, base stations may receive the reported UE-specific DRX cycle and apply that UE-specific DRX cycle for paging the UE in non-CE mode, while applying a different UE-specific DRX cycle from the more restrictive set for paging the UE in CE mode.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include establishing a connection between the UE and a network node of a non-terrestrial network, identifying, based on a synchronization failure event and while the UE is in a connected mode in accordance with establishing the connection, that a location failure condition has occurred for the connection, and performing, at least in part in response to the location failure condition, one or more actions of a location failure recovery procedure to restore a synchronization associated with the connection.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving, from a base station and at the UE of a group of UEs, control signaling indicating a link between a first search space set and a second search space set used for a multicast broadcast service, where a first downlink control channel for the group of UEs is transmitted in the first search space set and a second downlink control channel is transmitted in the second search space set, monitoring the first search space set for a first instance of control information in the first downlink control channel and the second search space set for a second instance of the control information in the second downlink control channel, and decoding the first instance or the second instance of the control information, or both, based on the monitoring.
