Title:
METHOD BY WHICH TERMINAL PERFORMS COMMUNICATION IN HETEROGENEOUS CELL ENVIRONMENT AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2015/002389
Kind Code:
A1
Abstract:
Disclosed are a communication performing method and terminal, and the method is a method by which a terminal with dual connectivity performs communication in a heterogeneous cell environment, in which: a first reporting message reporting that a downlink signal is received from a small cell in an intensity greater than a threshold value is transmitted to a macro cell; an RRC establishment message indicating a connection to a small cell cluster is received from the macro cell; connections are added to a plurality of small cells included in the small cell cluster according to additional time information included in the RRC establishment message; and the connections to the plurality of added small cells are respectively activated according to activation connection time information included in the RRC establishment message, and the small cell cluster is determined on the basis of information on a location relationship among the plurality of small cells.
