Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may provide a session request associated with establishing a proximity services (ProSe) session. The session request may include ProSe session specific information including information that indicates a ProSe service type associated with the ProSe session. The user equipment may receive a session establishment response after providing the session request. The session establishment response may include at least one of a ProSe session authorization indication associated with the UE, or ProSe policy information for the ProSe service type associated with the ProSe session. Numerous other aspects are provided.

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 user equipment (UE) may determine a prioritization rule that indicates a relative priority for different uplink communications included in a group of uplink communications, wherein the group of uplink communications includes at least a first uplink communication and a second uplink communication to be transmitted by the UE using time-division multiplexing during a make-before-break handover procedure. The UE may transmit, based at least in part on the prioritization rule, the first uplink communication to a target base station and the second uplink communication to a source base station using time-division multiplexing during the make-before-break handover procedure. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a master node (MN) may receive an acknowledgment message from a secondary node (SN). The MN and the SN may provide dual connectivity with a core network for a user equipment. The MN may provide an address indication message to the SN. The address indication message may include MN downlink transport network layer (TNL) information for an SN terminated data radio bearer (DRB) that requires master cell group (MCG) resources. The address indication message may be provided in a first message that immediately follows the acknowledgment message. In some aspects, the SN may receive the address indication message, and may forward, based at least in part on the MN downlink TNL information, downlink data for the SN terminated DRB that requires MCG resources. 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 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: Methods for performing a handover in wireless communications for a user plane function (UPF) are disclosed. In an aspect, the method includes establishing a tunnel between the UPF and a target base station based on information in a path switch preparation request for a make before break handover of a user equipment (UE) from a source base station to the target base station, the path switch preparation request being received in response to a request originating by the target base station. The method further includes bi-casting a downlink data packet unit (PDU) to a source base station and to the target base station with a same sequence number (SN) in a tunnel protocol, receiving PDUs from the source base station and the target base station with corresponding PDUs having the same SNs in the tunnel protocol and discarding received duplicate PDUs based on the SNs in the tunnel protocol.

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: In an embodiment, a UE performs an IRAT handoff from a source network with a first RAT to a target network with a second RAT, and obtains a channel from the target network. The UE reports a level of QoS on the channel to a server via the target network. The server issues instructions to the UE and/or the target network for modifying the level of QoS in response to the report based on if the level of QoS is insufficient to support a particular type of communication session. In another embodiment, in conjunction with an IRAT handoff, the source network sends a handoff preparation message to the target network to facilitate the target network to initiate setup of a set of channels with a non-IMS application-specific QoS configuration for the UE on the target network in conjunction with the handoff.

Abstract: In an embodiment, an apparatus (e.g., a client device or a server) sends, to a Long Term Evolution (LTE) network component, a request to setup a Quality of Service (QoS) bearer with a threshold level of QoS to support the communication session for the client device. The apparatus permits the client device to proceed with the attempt to setup the communication session irrespective of whether the LTE network component grants the threshold level of QoS for the QoS bearer. In another embodiment, the LTE network component rejects an initial QoS request from the apparatus due to QoS unavailability, and then receives another QoS request within a threshold period of time. Based on the two (or more) QoS requests being received within the threshold period of time, the LTE network component allocates an available level of QoS to the client device that is less than the requested level of QoS.

Abstract translation: 在一个实施例中，设备（例如，客户端设备或服务器）向长期演进（LTE）网络组件发送建立具有阈值QoS级别的服务质量（QoS）承载的请求，以支持 客户端设备的通信会话。 该设备允许客户端设备进行建立通信会话的尝试，而不管LTE网络组件是否向QoS承载授予QoS的阈值级别。 在另一个实施例中，由于QoS不可用性，LTE网络组件拒绝来自设备的初始QoS请求，然后在阈值时段内接收另一个QoS请求。 基于在阈值时段内接收到的两个（或更多个）QoS请求，LTE网络组件向小于请求的QoS级别的客户端设备分配可用的QoS水平。
