Abstract
Methods, apparatuses, and computer readable medium for enabling an efficient group handover mechanism that has less signaling overhead than single UE handover are provided. An example method at a base station includes transmitting a group handover request for the group of UEs to a target base station. The method further includes receiving a group handover acknowledgment from the target base station. The method further includes transmitting a group handover message to the group of UEs.
Claims29
An apparatus for wireless communication of a base station, comprising:
- memory;
- and
- at least one processor coupled to the memory and configured to:
- transmit a group handover request for a group of user equipment (UEs) to a target base station;
- receive a group handover acknowledgment from the target base station;
- and
- transmit a group handover message to the group of UEs based on a cell specific common search space, and wherein at least a portion of the group handover message is scrambled with a cell specific group radio network temporary identifier (RNTI).
An apparatus for wireless communication at a user equipment (UE) served by a source base station, comprising:
- memory;
- and
- at least one processor coupled to the memory and configured to:
- receive a group handover message comprising radio resource control (RRC) configuration for one or more UEs transmitted to a group of UEs comprising the one or more UEs from the source base station in a cell specific common search space, and wherein at least a portion of the group handover message is scrambled with a cell specific group radio network temporary identifier (RNTI);
- and
- connect to a target base station using the RRC configuration based on the group handover message.
