摘要： Methods, systems, and devices for wireless communications are described. A first user equipment (UE) (e.g., a remote UE) may establish a relay connection for communicating with a network entity (e.g., a base station or a network device) via a second UE (e.g., a relay UE). The relay connection may include a sidelink connection and an access link connection. The remote UE may transmit a request to the network entity via the relay UE. The request may include a relay service code associated with the sidelink connection, as well as a request for quality of service (QoS) support for the relay connection. Based on the request, the network entity may determine a QoS configuration for the relay connection. The network entity may indicate the QoS configuration to the UEs via the relay connection. The UEs may adjust parameters of the relay connection to meet the specifications of the QoS configuration.

摘要： 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.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may provide, to a source base station (BS) and prior to a handover of the UE from the source BS to a target BS, information that identifies a set of transition capabilities of the UE. The UE may receive, from the source BS, a handover command or reconfiguration message after providing the information to the source BS. The UE may communicate, using a subset of the transition capabilities, with the target BS prior to the release. Numerous other aspects are provided.

摘要： Methods, systems, and devices for wireless communications are described. Aspects include a UE communicating, with a first base station while in a connected state with a first cell served by the first base station, information associated with a configuration for the connected state via a signaling radio bearer and application via a data radio bearer. The UE may receive, while in the connected state with the first cell, a handover command from the first base station indicating a handover to a second cell served by a second base station. Aspects may include the UE initiating a connection procedure with the second cell while the connected state with the first cell. The UE may suspend the signal radio bearer and maintain the data radio bearer during the connection procedure with the second cell.

摘要： Techniques are described herein for signaling procedures that use a hierarchical mobility, which may be applied when a user equipment (UE) is operating in a radio resource control (RRC) inactive state or the RRC idle state. A wireless communication system may be configured with a plurality of areas in which one or more networks are established for communicating certain types of signals. Examples of the areas associated with networks may include a tracking area (TA), a radio access network area code (RAN-AC), a radio access network based notification area (RNA). A synchronization signal or a paging signal may be transmitted using a first set of communication resources in a first area, while the synchronization signal or the paging signal may be transmitted using a second set of communication resources in a second area different than the first set of communication resources.

摘要： Systems and methods are described herein for providing a virtual conference using a master device implemented with a personal communication device (PCD), including determining, by the master device, a latency for each of a plurality of satellite devices connected to the master device. The master device then determines an uplink buffer duration based on a difference between a highest latency and a lowest latency among the plurality of satellite devices. The master device determines a processing time for an uplink data packet, the processing time being determined based, at least in part, on the uplink buffer duration. The master device then performs signal processing at the processing time for the received uplink data packets.
