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: 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) may receive cell characteristic information of multiple network nodes associated with different network architectures. The UE may select a network node, from the multiple network nodes, based at least in part on a mapping rule and the cell characteristic information, wherein the mapping rule is associated with UE information and cell or network information. The UE may transmit a random access channel (RACH) message to establish a connection with the network node. Numerous other aspects are described.

Abstract: The apparatus may be a wireless device configured to receive a set of security parameters associated with one of a layer 1 (L1) link reestablishment procedure or a layer 2 (L2) link reestablishment procedure, detect a failure of a radio link at the wireless device. The apparatus may further be configured to transmit, for a network node, at least one of an L1 link recovery request or an L2 link recovery request, including an authentication value based on the set of security parameters, and receive, based on at least one of the L1 link recovery request or the L2 link recovery request, a link recovery message.

Abstract: This disclosure provides methods, components, devices and systems for enhanced downlink and uplink scheduling based on assistance information related to PDCP status reports. Some aspects specifically relate to a wireless communication system including a disaggregated base station architecture in which a CU provides a DU assistance information related to PDCP status reports from which assistance information the DU may determine appropriate downlink or uplink scheduling start timing for a UE. In some examples, the DU obtains from the CU assistance information indicating an unreceived PDCP SDU at a UE or the CU, and sends downlink data or an uplink grant to the UE based on the assistance information. The CU may deliver the downlink data to the DU prior to sending the assistance information or obtain uplink data from the DU after sending the assistance information. Duplication of PDCP SDU transmissions and unnecessarily extended scheduling delays may thus be minimized.

Abstract: A target cell receives a handover message originating from a source cell for a user equipment (UE) and receives buffered data for one or more protocol data unit (PDU) Sets in transition between the source cell and the UE. The target cell receives PDU Set information for the one or more PDU Sets and communicates with the UE based on the PDU Set information for the one or more PDU Sets. A source cell sends or receives a portion of a PDU Set with a UE. The apparatus initiates a handover of the UE to a target cell, provides buffered data for the PDU Set to the target cell, and provides PDU Set information for the PDU Set to the target cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, via a first cell, multicast radio bearer (MRB) configuration information indicating one or more MRB configurations for receiving multicast communications. The UE may receive, via a second cell, a multicast communication based at least in part on an MRB configuration of the one or more MRB configurations. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may support both unicast and multicast downlink signaling, such as on a single component carrier (CC). A UE may receive a unicast message over a first CC during a transmission time interval (TTI) using a first set of processing resources. The UE may simultaneously receive a multicast message over the first CC during the same TTI using a second set of processing resources. The first and second sets of processing resources may be associated with first and second hybrid automatic repeat request (HARM) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may access a serving network via a satellite while in a first state with the serving network, the first state comprising a connected state. The UE may transmit, to the serving network and based on a determination that a coverage gap associated with the satellite is upcoming, a coverage gap indication that indicates that the coverage gap is upcoming. The UE may transition from the connected state to a second state at or before a start of the coverage gap. Numerous other aspects are described.
