摘要:
A secondary carrier activation/deactivation method for activating/deactivating secondary carriers in addition to a primary carrier is provided for a mobile communication system supporting carrier aggregation. The method includes identifying, when a secondary carrier control message is received from a base station, carriers to be activated are deactivated, determining, when the message includes a secondary carrier activation command, whether a first time point has arrived, and executing, when the first time point arrives, predetermined first operations. The present invention is advantageous to avoid malfunctions in communication system supporting carrier aggregation by defining UE operations to be taken in SCell activation and deactivation.

A dual mode terminal and controlling method thereof are disclosed. The present invention includes a first antenna and a second antenna. In particular, a signal received via the second antenna includes a signal generated from multiplexing an LTE downlink signal, a CDMA DCN (data core network) downlink signal and a CDMA PCS (personal communication services) downlink signal. And, the present invention is characterized in including a triplexer for demultiplexing of the downlink signals. Accordingly, a dual mode terminal of the present invention is able to receive an LTE signal without a data rate fall in the course of measuring a quality of a CDMA signal.

There is provided a hydrogen generator. The hydrogen generator including: an electrolytic bath having an inner space of a predetermined size; a cover hermetically covering an open top of the electrolytic bath and having at least one hydrogen outlet; a flexible pocket disposed in the electrolytic bath and filled with an electrolyte of a predetermined amount; an electrode part fixed to the cover, and immersed in the electrolyte filled in the flexible pocket to electrolyze the electrolyte upon application of power; and a power supply supplying current to the electrode part. In the hydrogen generator, the electrode part and the electrolyte maintains a substantially constant contact area there between, thereby allowing hydrogen to be generated constantly and stably.
