Title:
WIRELESS COMMUNICATION SYSTEM, DIFFERENT-FREQUENCY HANDOVER METHOD, BASE STATION, AND TERMINAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/175947
Kind Code:
A1
Abstract:
[Problem] When a URLLC packet is transmitted between a base station and a terminal apparatus and a GAP period in a different-frequency handover has been set, there may be a case where a delay-related specification provided for the URLLC packet is not met. [Solution] In a different-frequency handover, when a conflict occurs between a processing such as a reception quality measurement in a GAP period and the transmission of a URLLC packet for which a delay-related specification is provided, the delay in transmission of the URLLC packet can be suppressed by performing a cancelation or the like of the GAP period and thereby executing the transmission of the URLLC packet on a priority basis.
