METHOD FOR CONTROLLING BEARER EXTENSION IN HETEROGENEOUS NETWORK WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR SAME

摘要

The present invention relates to a method for controlling a bearer extension in a heterogeneous network wireless communication system and an apparatus for same. The present invention discloses a method for supporting a modification of an extended EPS bearer, comprising the steps of: receiving from a macro base station first uplink transmission starting information and first uplink transmission withholding information; receiving from the macro base station a parameter for configuring a radio bearer, which is mapped onto a second extended EPS bearer to be formed between user equipment and a second small base station, and second uplink transmission withholding information; and receiving from the macro base station third uplink transmission withholding information and second uplink transmission starting information.
