    Abstract: A traffic mobility method between heterogeneous access networks of a wireless communication system includes, as a user equipment (UE) multiply accesses a first access network and a second access network, configuring a first transmission path corresponding to the first access network and a second transmission path corresponding to the second access network with respect to the UE, by a gateway, determining whether traffic mobility is performed on each traffic flow based on a traffic mobility policy of the each traffic flow served to the UE through the first transmission path and a transmission state of the second access network, by a control entity, and changing a transmission path of a traffic flow on which traffic mobility is determined, to the second transmission path from the first transmission path, by the gateway.

    Abstract: An operation method of a first cell in a communication system may include: receiving, from a first communication node that is an upper node of the first cell, a first signal including second cell configuration information of a second cell connected with the first communication node and a second communication node that is a lower node of the first cell; identifying, based on the first signal, that the first cell and the second cell are jointly operated by the first communication node as coordinative PCells; transmitting, to the second communication node, a second signal including information on joint operations of the coordinative PCells by the first communication node; and performing communication with the first communication node and the second communication node based on the joint operations of the coordinative PCells.

    IPC: H04W16/28

    Abstract: An operation method of a terminal in a communication system may comprise: obtaining a plurality of serving beam measurement values by performing measurement on a plurality of serving beams; identifying a minimum measurement value among the plurality of serving beam measurement values; obtaining a plurality of beam measurement values by performing measurement on a plurality of beams received from a plurality of base stations included in the communication system; determining whether a first condition is satisfied, the first condition being defined based on a result of comparison between the plurality of beam measurement values and a sum of the minimum measurement value and a first offset; and in response to determining that the first condition satisfied, performing communication with at least part of the plurality of serving base stations and a first base station forming a first beam satisfying the first condition.
