Title:
WIRELESS COMMUNICATION SYSTEM AND WIRELESS BASE STATION
Document Type and Number:
WIPO Patent Application WO/2019/097652
Kind Code:
A1
Abstract:
In this wireless communication system, a split bearer is set so as to pass through a secondary cell group from a core network and to branch from a gNB100B included in the secondary cell group toward an eNB100A included in a master cell group, and data is transmitted through the split bearer to a user device. The gNB100B transmits, to the eNB100A, "Use of SCG Radio Resource" indicating whether to form the split bearer using a wireless resource between the user device and the gNB100B. The eNB100A sets the split bearer on the basis of the received "Use of SCG Radio Resource".
