Abstract:
A method for transmitting data in a multiple input multiple output (MIMO) wireless communication system is disclosed. The method for transmitting a signal to a receiver by a transmitter in a multiple input multiple output (MIMO) wireless communication system includes: generating a bit stream having the size of specific bits through channel coding of data; dividing the bit stream into a first bit stream having a first bit size and a second bit stream having a second bit size; allocating the second bit stream having the second bit size to an antenna sequence codeword on the basis of a signal transmission time; and transmitting the first bit stream having the first bit size to the receiver according to an order of antenna pairs indicated by the allocated antenna sequence codeword.
Abstract:
A device for transmitting and receiving multi-input multi-output (MIMO) signal in a wireless communication system in which a plurality of communication systems is present includes a plurality of antenna modules and a recognition module for recognizing at least one of network information or antenna information of a source device. The recognition module compares a measurement result of the plurality of antenna modules with pre-stored information to recognize the network information or antenna information of the source device.

An apparatus for boosting an MIMO (multi-input multi-out-put) signal and method thereof are disclosed. The present invention includes determining an initial transmit power value of the signal booster and applying an initial transmit power increment/decrement value to a sum of the initial transmit power value and the initial transmit power increment/decrement value in each preset time interval during an initial power control period.
Abstract:
The present invention relates to a method in which a signal is transmitted between a base station and a terminal in a multi-antenna wireless communication system. The method transmits pre-estimated channel information to the terminal when the terminal moves to a specific position when channel estimation for a specific position is performed. As for the terminal which moves along a fixed route or the route of which can be estimated, the position of the terminal in the near future can be easily detected. Therefore, the transception of channel information can be performed in a more efficient manner in consideration of the above-described special environment.

The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for transceiving a downlink control channel. According to one embodiment of the present invention, method in which a base station transmits downlink control information in a wireless communication system comprises: a step for determining an allocatable resource region for an enhanced physical downlink control channel (E-PDCCH) of a local allocation system; a step for allocating an E-PDCCH to the determined allocatable resource region for the E-PDCCH; and a step for transmitting the downlink control information on the allocated E-PDCCH. The allocatable resource region for the E-PDCCH can be set as a group of partial resource regions in each of a plurality of partitions when a downlink system bandwidth contains said plurality of partitions.
