Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a reception occasion for a short message that includes a system information change notification or a public warning system notification. The UE may initiate a mitigation action related to a radio link with a network based at least in part on non-reception by the UE of the short message in the reception occasion, failure of the short message to pass an integrity check, and/or the like. 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 a configuration for a multicast or broadcast radio bearer (MRB) in a radio link control (RLC) acknowledged mode (AM). The UE may determine an adjustment of an RLC AM transmission window of a base station. The RLC AM transmission window may be associated with retransmission of RLC packets associated with the MRB. The UE may synchronize an RLC AM reception window of the UE with the RLC AM transmission window based at least in part on determining the adjustment of the RLC AM transmission window of the base station. The RLC AM reception window may be associated with reassembly of RLC packets associated with the MRB. 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 a configuration for a shared physical downlink shared channel (PDSCH). The UE may receive a first communication via the shared PDSCH and a first bearer based at least in part on the configuration, the first communication being one of a unicast communication or a multicast/broadcast communication. The UE may receive a second communication via the shared PDSCH and the first bearer or a second bearer based at least in part on the configuration, the second communication being the other of the unicast communication or the multicast/broadcast communication. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may receive an indication of a traffic pattern for application traffic. The BS may determine, based at least in part on one or more measurements associated with the traffic pattern, one or more parameters for at least one of a discontinuous reception (DRX) configuration for the application traffic, or a semipersistent scheduling (SPS) configuration for the application traffic. The BS may transmit, to a user equipment (UE) that is to receive the application traffic, an indication of the at least one of the DRX configuration or the SPS configuration. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for traffic burst awareness in wireless systems. An application function, such as via an application server, can determine one or more burst parameters associated with a traffic flow for at least one service. The application function can send the one or more burst parameters a network. The burst parameters may include a burst factor associated with a minimum bit rate for providing service coverage for the traffic flow and/or a burst spread. A core network and/or access network (AN) entity can obtain the burst parameters and utilize the burst factor for communicating with a user equipment (UE). The CN and/or AN may use the burst parameters for admission control, resource allocation, and/or setting sleep mode parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit to a base station (BS), information indicating a medium access control (MAC) security capability of the UE. The UE may receive from the BS, a communication that includes an indication of a MAC security configuration for communications between the UE and the BS. The indication of the MAC security configuration may be based at least in part on the MAC security capability of the UE. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to mechanisms for interworking between legacy and next generation radio access technologies (RATs) in a communication network. In some examples, a handover from a next generation access network to a legacy access network may be performed via a next generation core network and a legacy core network. A handover request received at a next generation core network serving node may include an identifier of a target cell within the legacy access network. The next generation core network serving node may identify a legacy core network serving node to which the handover may be forwarded based on the target cell identifier. Packet data units may then be routed over the legacy access network and the next generation core network by mapping data flows in the next generation core network to packet data connections in the legacy access network.

Abstract: Aspects presented herein provide an enhanced power management solution, such that an apparatus may configure a UE with more than one DRX configuration for different cells. The apparatus determines a configuration of a plurality of discontinuous reception (DRX) groups for communicating with a UE. The apparatus configures the UE with a first DRX group for a first set of serving cells. The apparatus configures the UE with a second DRX group for a second set of serving cells.
