Title:
METHOD AND APPARATUS FOR CONTROLLING CARRIER AGGREGATION FOR NEXT GENERATION WIRELESS NETWORK
Document Type and Number:
WIPO Patent Application WO/2019/013543
Kind Code:
A1
Abstract:
The present invention relates to a method comprising the steps of: receiving, from a terminal, measurement report information of a cell; determining, by a concentration node, a carrier aggregation configuration for a terminal by using a cell including one or more distribution nodes; determining, by the concentration node or distribution node, a secondary cell state of each of one or more secondary cells configured for the terminal, using the measurement report information and information on the amount of downlink data received from a core network entity; and transmitting, by the distribution node, information indicating the secondary cell state of the secondary cell to the terminal, wherein the concentration node is a logical node hosting an RRC layer, an SDAP layer, and a PDCP layer, the distribution node is a logical node hosting an RLC layer, an MAC layer, and a PHY layer, and the concentration node and one or more distribution nodes transmit or receive information via an F1 interface.
