    摘要： A random jitter beamforming method for reducing the influence of a side lobe to decrease a beam width, and a transmitter and a receiver using the same are provided. The random jitter beamforming method includes dividing a series of binary sequences to generate a plurality of bit groups, designating a beam pattern, corresponding to each of the bit groups, from a set of two or more beam patterns having the same gain and phase in a target direction, and forming a beam with the corresponding beam pattern, for each of the bit groups.

    摘要： A first terminal generates a first scheduling request signal including information about first data resources for data transmission when the first terminal tries to reserve the first data resources. The first terminal generates a first scheduling request indication signal providing notification that the first scheduling request signal is to be transmitted. The first terminal transmits the first scheduling request indication signal through a first request subslot included in a first scheduling request resource before transmitting the first scheduling request signal. The first terminal transmits the first scheduling request signal through a second request subslot included in the first scheduling request resource.

    摘要： A method and apparatus for a mobile communication terminal to recognize a target mobile communication terminal using a location recognition system. The method includes acquiring own location information of the mobile communication terminal; creating identification verification information using the location information, the identification verification information containing an identification formula for identifying the target mobile communication terminal as a target of communication; transmitting the created identification verification information to at least one other mobile communication terminal within a communication coverage area; receiving an identification response packet from the at least one other mobile communication terminal which has received the identification verification information, the identification response packet indicating whether the other mobile communication terminal is a target mobile communication terminal; and determining the target mobile communication terminal based on the received identification response packet.
