Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a set of measurements related to a unicast service channel based at least in part on one or more reference signals associated with the unicast service channel and a set of measurements related to a multicast/broadcast service (MBS) channel based at least in part on one or more reference signals associated with the MBS channel. The UE may apply one or more communication parameters to ensure continuity for an MBS service. For example, in some aspects, the one or more communication parameters are based at least in part on the set of measurements related to the unicast service channel and the set of measurements related to the MBS channel. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate generally to communication systems, and more particularly, to enhanced reporting by user equipment (UE). An example method generally includes receiving an information request from a network node and in response, sending a message to the network node, wherein the message comprises information that allows the network node to determine a starting coverage enhancement (CE) level of the UE.

Abstract: A UE transmits to a source base station a capability of the UE associated with a bandwidth class or a band combination. The capability is associated with a handover in which the UE maintains connections with the source base station and a target base station. The UE receives a handover message comprising at least one of a target base station configuration to apply during handover execution or a source base station configuration to apply during handover execution based on the capability of the UE. The UE establishes a connection with the target base station and maintains a connection with the source base station over a period of time during the handover. The UE communicates with the source base station and the target base station during handover execution using at least one of the target base station configuration or the source base station configuration.

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: A wakeup signal (WUS) group that may be divided into WUS sub-groups, criteria or metrics for dividing the WUS group into a set of WUS sub-groups, and signaling or messaging to support the division of the WUS group into the set of WUS sub-groups are provided. For example, a set of UEs may be divided into WUS sub-groups based at least in part on respective frequencies of occurrence of paging occasions for the set of UEs (e.g., based at least in part on traffic type, observations regarding past paging occasions, predictions regarding future paging occasions, and/or the like) and/or based at least in part on other considerations. Furthermore, some techniques and apparatuses described herein provide for the mapping of network device-level WUS sub-groups (e.g., supported by a network device such as an MME) to base station-level WUS sub-groups (e.g., supported by a base station).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive information indicating whether measurement is permitted on a non-anchor carrier; and selectively perform a measurement on at least one of the non-anchor carrier or an anchor carrier, based at least in part on the information indicating whether the measurement is permitted on the non-anchor carrier. 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 source base station (BS), an indication that the UE is to perform a conditional handover from the source BS to a target BS and is to perform at least one of: a two protocol stack handover from the source BS to the target BS or a dual connectivity handover from the source BS to the target BS. The UE may perform the conditional handover and at least one of the two protocol stack handover or the dual connectivity handover based at least in part on the indication. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) receive a first control format indicator (CFI) value in a message that is not carried via a physical control format indicator channel (PCFICH); may determine whether the UE is operating using at least one of a first configuration with which the first CFI value is to be used or a second configuration with which a second CFI value, indicated in the PCFICH, is to be used; and may operate using at least one of the first CFI value or the second CFI value based at least in part on determining whether the UE is operating using the at least one of the first configuration or the second configuration. 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 provide information identifying a band combination capability for carrier aggregation during a handover of the UE, wherein the band combination capability identifies a plurality of bands or carriers; and perform the handover based at least in part on the information identifying the band combination capability, wherein at least one first band or carrier, of the plurality of bands or carriers, is used for a source base station of the handover and at least one second band or carrier, of the plurality of bands or carriers, is used for a target base station of the handover. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a control message indicating one or more decryption keys for multicast and broadcast service (MBS) communications within a geographic service area supported by one or more cells of a non-terrestrial network (NTN) or a terrestrial network (TN). The UE may also receive geographic information associated with the geographic coverage area, synchronization information associated with the one or more cells, prioritization information associated with the one or more cells, or a combination thereof. Accordingly, the UE may receive an MBS message via the one or more cells, and may decrypt the MBS message based on the control message, the geographic information, the synchronization information, the prioritization information, or a combination thereof. The techniques described herein may enable the UE to receive encrypted MBS communications within the geographic service area.
