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: Methods, systems, and devices for wireless communications are described for a handover procedure that allows a user equipment (UE) to keep both the source and the target base station until after handover is complete while using a single packet data convergence protocol (PDCP). In the procedure, a source base station may decide to configure bearers as split bearers during handover. Then, the source base station may transmit a handover request to the target base station, and the radio bearer configuration is added to the handover preparation and response messages. The target base station may transmit the decision on the proposed configuration in a handover response message to the source base station. The source base station may transmit a handover command to the UE with the radio bearer configuration, and the UE may configure its bearers and will maintain the split bearer configuration until the UE receives a new bearer configuration.

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: This disclosure provides systems, methods and apparatuses, including computer programs encoded on computer storage media, for uplink switching for enhanced mobility. In some aspects, this disclosure provides techniques for potentially reducing or eliminating service interruptions experienced during a handover from a source cell to a target cell. Additionally, this disclosure provides techniques for potentially simplifying or improving uplink communications while a UE is connected to both the source cell and the target cell during the handover. This disclosure further provides techniques for potentially reducing UE power consumption or improving uplink resource utilization during a handover from a source cell to a target cell while a UE is connected to both the source cell and the target cell during the handover.

Abstract: Various aspects and techniques for facilitating handovers in communication networks are disclosed. In a particular implementation, a method of wireless communication includes transmitting, from a first base station to a second base station, a handover request message corresponding to a user equipment (UE) associated with the first base station. The handover request message includes a request for full configuration. The method further includes receiving, from the second base station, a handover response message. The handover response message includes an indicator of acceptance of the full configuration. Other aspects and features are also claimed and described.

Abstract: The disclosure relates to determining priority access with dual access barring classes. An aspect receives, at a client device, at least one high priority access barring class and at least one low priority access barring class, switches to the low priority access barring class, receives an access barring message, and switches to the high priority access barring class in response to receiving the access barring message. An aspect receives a call request for a high priority call among a group of client devices, transmits a notification to a network instructing it to transmit an access barring message in response to receiving the call request, wherein one or more members of the group of client devices switch to a high priority access class in response to receiving the access barring message, and suppresses call announcements for non-priority call requests after transmitting the notification.
