Abstract: Methods, systems, and devices for wireless communications are described for management of conditional handover (CHO) configurations. A source base station may configure a user equipment (UE) with one or more CHO configurations for multiple target base stations. The CHO configurations may provide, for each target base station, one or more associated conditions that may trigger the UE to initiate a handover to the particular target base station, or to deconfigure a CHO configuration, such as based on a measurement threshold of one or more target base station measurements, one or more source base station measurements, or combinations thereof. The CHO configurations may also include failure handling information for initiating one or more subsequent handovers responsive to a failure of an initial handover attempt.

Abstract: This disclosure provides systems, methods and apparatus for determining a target base station timing advance value between a user equipment (UE) and target base station in connection with a random access channel (RACH)-less handover procedure. In one aspect, the UE may determine the target base station's timing advance based at least in part on a timing difference between the target base station and the source base station and based at least in part on a timing offset associated with an uplink and a downlink of the UE. In some aspects, the target base station may determine the timing advance using an uplink reference signal of the UE. In some aspects, the UE may report a timing difference between the target base station and the source base station, and the source cell may determine a timing advance based at least in part on the timing difference.

Abstract: 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.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, handling header compression in scenarios with concurrent connections, such as make-before-break (MBB) handover or dual connectivity (DC) scenarios. A method of wireless communication performed by a user equipment (UE) can include concurrently communicating with a first base station (BS) on a connection with the first BS and with a second BS on a connection with the second BS during a handover procedure. The UE maintains a context for a header compression protocol for the connection with the first BS and the connection with the second BS. The concurrently communicating includes using the header compression protocol context for sending one or more packets, receiving one or more packets, or both.

Abstract: Methods, systems, and devices for wireless communications are described that provide a handover may be performed based on one or more conditions at a UE and in conjunction with a handover procedure from a source base station to a target base station. The one or more conditions at the UE may be associated with successful establishment or maintenance of the second connection. In some cases, the one or more conditions at the UE may correspond to one or more measurements associated with the source base station, the target base station, one or more neighboring base stations, or any combinations thereof.

Abstract: The present disclosure relates to methods and devices for a handover procedure which may include a user equipment (UE), first base station, and a second base station. In one aspect, the UE can receive an indication to handover from the first base station to the second base station. The UE may then establish a connection with the second base station. In another aspect, the UE can maintain a connection with the first base station over a period of time during the handover. The UE can also communicate with the first base station and the second base station during the period of time based on a time division multiplexing (TDM) pattern. The TDM pattern can comprise a pattern of subframes for communicating with the first and second base station. In another aspect, the UE can release the connection with the first base station at the end of the period of time.

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.
