Problems solved by technology

However, the source base station may not know that the UE is performing a triggered CHO order or performing target cell selection
As a result, the source base station does not know the exact time to stop the downlink data transmission to the UE and / or start the data forwarding to the target base station, and may not even know in advance to stop the downlink data transmission to the UE and / or start the transmission to the target base station. Target base station data transfer

Abstract

In some embodiments, a method for Conditional Handover (CHO) is described. The method may receive one or more CHO commands from a source base station (eg, gNB or eNB), each CHO command is associated with one or more trigger conditions to CHO to a target base station (eg, target gNB or target eNB) ) associated target cell. The method may continuously evaluate trigger conditions associated with each received (and valid) CHO command. When the method judges that at least one of the trigger conditions is satisfied, the method may execute the CHO command associated with the trigger condition to link to one or more candidates associated with the CHO command target area.

Description

[0001] Cross References to Related Applications [0002] This application requests the benefit and priority of U.S. provisional application No. 62 / 616,785 submitted on January 12, 2018, whose invention name is Conditional Handover Procedure, and whose attorney docket number is US72116 (hereinafter referred to as US72116 application). The application content of the US72116 application is hereby fully incorporated by reference into this application. technical field [0003] The present disclosure relates generally to wireless communications and, more particularly, to conditional handover procedures. Background technique [0004] In a wireless communication network (such as the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN)), one of the main reasons for the handover failure is that the user equipment (User Equipment, UE) does not communicate from the source base station ( For example: the source evolved NodeB (e...
