Abstract:
A multi module communication apparatus and a data transmitting and receiving method using the same are provided to exchange a signal for controlling power supply of plural wireless communication modules included in the multi module communication apparatus by using a low power communication channel, thereby minimizing the whole power consumption. A selection information receiver(430) receives communication module selection information for instructing to select one of plural wireless communication modules(412,413) through a wireless channel(211) provided by a low power communication module(411). A power controller(440) supplies power by selecting a wireless communication module designated by the communication module selection information received through the selection information receiver. A data transceiver(450) transmits or receives data through a wireless channel(212,213) provided by the selected wireless communication module.

Abstract:
PURPOSE: A cooperative interference control method between multiple cells and a device using the same are provided to effectively assign voltages to a sub-channel of terminals included in a cooperative cluster by using a cooperative method between nodes. CONSTITUTION: A frequency resource assignment unit(610) assigns frequency resources used in a cooperative cluster to a plurality of exclusive bands and a reuse band according to an FFR(Fractional Frequency Reuse) method. A mode selecting unit(620) selects one mode related to the assignment of a sub-channel for terminals included in the cooperative cluster based on power consumption consumed in the cooperative cluster. A sub-channel assignment unit(630) assigns sub-channels for the terminals according to the selected mode.

Abstract:
PURPOSE: In the system which the communications method and apparatus thereof uses the statistical multiplexing, by getting data based on the pilot signal the collision of the pilot signal can be shirked and the channel constant can be decided. CONSTITUTION: The carrier signal which is transmitted by using the orthogonal resources is received(S410). Data obtains from the received carrier signal. Data obtains based on the pilot signal within the carrier signal(S420). The pilot signal is included within the carrier signal so that collision generate between the group. The pilot signal is transmitted from the resources element different at the group. The presence of the pilot signal is determined(S430).
