Title:
METHOD AND APPARATUS FOR CONTROLLING RADIO RESOURCE FOR A REDUNDANT ROUTE FOR A DUAL-CONNECTING IAB-NODE IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/149653
Kind Code:
A1
Abstract:
A method and apparatus for controlling radio resource of a redundant route for a dual-connecting Integrated Access and Backhaul (IAB) node in a wireless communication system will be provided. The CU of the IAB-donor is connected with a dual-connecting IAB-node via a master cell group (MCG) IAB-node. The CU of the IAB-donor initiates an establishment of a connection with the dual-connecting IAB-node via a secondary cell group (SCG) IAB-node. The CU of the IAB-donor transmits, to the SCG IAB-node, a first information which informs not allocating radio resource for a bearer. The CU of the IAB-donor determines to use the connection with the dual-connecting IAB-node via the SCG IAB-node. The CU of the IAB-donor transmits, to the SCG IAB-node, a second information to request allocating the radio resource for the bearer.
