Title:
METHODS FOR USER EQUIPMENT CAPABILITY REPORTING OF SIMULTANEOUS CONNECTIVITY HANDOVER
Document Type and Number:
WIPO Patent Application WO/2021/063371
Kind Code:
A1
Abstract:
Aspects of the present disclosure propose solutions to a problem of mobility interruption during handover between base stations by providing a UE with mechanisms to report the UE capability for simultaneous connectivity based handover, or so-called Dual Active Protocol Stack Handover (DAPS-HO). A UE reports the DAPS-HO capability of the UE to the network and then the base station initiates physical layer procedures to carry out DAPS-HO in accordance with the DAPS-HO capability reported by the UE. Aspects of the present disclosure also provide examples of signaling that may be used by the UE for reporting DAPS-HO capability to the network and the physical layer procedures that the UE may follow in accordance with the configuration that the network provides to the UE, which should be in accordance with the UE's capability.
