Method of allocating radio resources and apparatus of allocating radio resources in small-cell networks

Resource allocation method according to the invention, obtaining the available channel information, the cognitive radio small cell, the method comprising: dividing the required transmission rate of the radio small cell recognition and analysis of the channel characteristics on the basis of available channel information to an available channel request rate , and on the basis of the specific requirements, dividing the available channel data rate and a step for performing power control for each available channel. Resource allocation method according to the invention is that the small radio cells are present, and plural dog can be carried out in the interference environment to share the available channels between the plurality of cognitive radio small cells.
