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, an indication that indicates whether a common search space (CSS) is associated with a first type of physical downlink control channel (PDCCH) or a second type of PDCCH. The first type of PDCCH may correspond to a cell-broadcast PDCCH and the second type of PDCCH may correspond to a UE-specific PDCCH. The CSS may be for downlink control information (DCI) with a cyclic redundancy check scrambled by a group radio network temporary identifier (G-RNTI) that schedules a multicast and broadcast service (MBS). The UE may receive, from the base station, the first type of PDCCH or the second type of PDCCH. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described in which paging messages may provide an indication of a service that caused the page, and a receiving user equipment (UE) may determine a paging response based on a UE status and the service that caused the page. The paging response may include ignoring the page, a paging response with a busy indication, or a paging response after a time delay, for example. The paging message may be received at an access stratum (AS) layer of the UE, and the AS layer may provide the paging message to a non-access stratum (NAS) layer along with the indication of the service that caused the page. The NAS layer may determine the paging response.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques performing measurement reporting. One aspect is a method for performing measurement reporting at a user equipment, including: receiving, from a master node, a message comprising a measurement configuration for a secondary node; entering an inactive state; performing measurements according to the measurement configuration for the secondary node immediately after entering the inactive state; generating a measurement report based on the measurements; transmitting, to the master node, an RRC resume request message; receiving, from the master node, an RRC resume message comprising a request for measurement reporting; and transmitting, to the master node, an RRC resume complete message comprising the measurement report; and receiving data from the secondary node.

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: Aspects of the present disclosure relate to wireless communications, and more particularly, handling header compression in scenarios with concurrent connections, such as make-before-break (MBB) handover or dual connectivity (DC) scenarios. A method of wireless communication performed by a user equipment (UE) can include concurrently communicating with a first base station (BS) on a connection with the first BS and with a second BS on a connection with the second BS during a handover procedure. The UE maintains a context for a header compression protocol for the connection with the first BS and the connection with the second BS. The concurrently communicating includes using the header compression protocol context for sending one or more packets, receiving one or more packets, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect that a timer has expired prior to completing a handover of the UE from a source base station (BS) to a target BS. In some aspects, the UE may selectively declare, based at least in part on detecting that the timer has expired, a radio link failure. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for slice-aware network selection. Particular aspects provide for a method for wireless communication performed by a user equipment (UE). The method generally includes obtaining, for one or more networks, network slicing information indicating one or more slice identifiers supported in the one or more networks, deriving a list of one or more preferred networks based, at least in part, on the network slicing information, and selecting a network to register with from the list of one or more preferred networks.

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: Various aspects provide a method for radio resource allocation to support multicast services from a 5G-NR base station. In some aspects, the method may be performed by a processor of the base station. Various aspects include determining a multicast bandwidth part (BWP) within a carrier bandwidth, sending an indication of the multicast BWP to one or more user equipment (UE) computing devices in communication with the base station, and scheduling transmission of multicast data in the multicast BWP.
