    Abstract: The user equipment (UE) may obtain at least one optical reference signal associated with a transmit receive point (TRP), the at least one optical reference signal including at least one of: a TRP identifier (ID) or direction information of the at least one optical reference signal with reference to the TRP. The UE may identify information associated with the TRP with reference to the UE based on the at least one optical reference signal, and perform at least one of a cell acquisition, a beam management, a UE position detection, a TRP validation, or an ambient environment detection based on the identified information associated with the TRP. The UE may also receive at least one reference radio signal, and use the correlation between the optical reference signal and the received reference radio signal.

    Abstract: Wireless communications systems and methods related to on-demand ultra-reliable, low-latency communication (URLLC) are provided. In one embodiment, a base station (BS) receives, from a user equipment (UE) in a first cell frequency, a request for a protocol data unit (PDU) session over a network slice. The BS receives, from a core network entity, a resource configuration request for the PDU session over the network slice. The BS transmits, to the core network entity, a resource configuration response indicating a cause for rejecting the resource configuration request. In one embodiment, a UE transmits, in a first cell frequency of a network, a network registration request message requesting a network slice of the network that is not provided by the first cell frequency. The UE receives a network registration response message indicating the network slice is allowed based on a second cell frequency of the network providing the network slice requested.

    Abstract: Embodiments include systems and methods for supporting for supporting retransmission in a multicast session in a Fifth Generation (5G) New Radio (NR) (5G NR) radio access network (RAN). Various embodiments may provide an enhanced multicast radio bearer (MRB) architecture leveraging Packet Data Convergence Protocol (PDCP) status reporting by wireless devices to a base station of a 5G NR RAN. Various embodiments may support multiple Radio Link Control (RLC) entities, also referred to as RLC legs, in a multicast session. One or more multicast RLC legs may be used for multicast and/or unicast transmission to wireless devices and a unicast RLC leg may be used for unicast transmission to a specific wireless device. Various embodiments may enable PDCP level retransmission of PDCP protocol data units (PDUs).

    Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to performing a handover on a per-data radio bearer (DRB) basis. In some examples, the disclosure is directed to indicating, to a source network entity, a make-before-break (MBB) handover capability of the UE, the MBB handover capability supporting MBB handovers for one or more DRBs identified by the source network entity. In some examples, the disclosure describes receiving, from the source network entity, configuration information for a handover from the source network entity to a target network entity, the configuration information identifying the one or more DRBs supported for the MBB handover.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive, from a source master node, a secondary node release request corresponding to a conditional handover operation associated with a user equipment (UE) operating in accordance with multiple radio access technology dual connectivity, wherein the secondary node release request indicates that the network node is to continue to be a secondary node associated with the UE or that a target secondary node is to be the secondary node associated with the UE. The network node may perform a data transfer operation based at least in part on receiving the secondary node release request. Numerous other aspects are described.

    Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may directly send small data to a disaggregated base station without performing a random access procedure. The CU-CP may provide a list of routing identifiers and corresponding data resource bearers (DRBs) to a distributed unit (DU) and the DU may transmit a connection release message to the UE. The connection release message may include the list of routing identifiers and the list of DRB identifiers. The connection release message may also include a downlink monitoring timer. The UE may identify data for an uplink transmission and a DRB associated with that data. The UE may transmit a packet with the data and the routing identifiers to a DU, which may derive downlink address information from the routing identifiers and forward the data to a CU-UP of the aggregated base station.
