Apparatus and method for dynamically allocating radio resource
The invention relates to a communication device and method that dynamically uses frequency resources, and more particularly, to a mobile terminal and a communication method that can dynamically allocate frequencies. The mobile terminal, which can dynamically allocate frequencies includes a communication module including a cognitive engine and a communication system block. The cognitive engine searches frequency bands based on both specific frequency policy and a service chosen by the user and selects a specific frequency band from the searched frequency bands. The communication system block includes a platform block for performing configuration for the selected frequency band and at least one component block for performing data processing based on a specific protocol according tox the configuration of the platform block.
1. A method for a terminal to receive data using a plurality of frequency band cells, the method comprising;
acquiring frequency bands information on which of frequency bands a measurement can be performed and on which of the frequency bands the measurement cannot be performed, wherein the frequency bands information is acquired from outside of the terminal;
performing the measurement on the frequency bands on which the measurement can be performed based on the frequency bands information;
acquiring measurement result information on the plurality of frequency band cells based on the measurement;
receiving, by the terminal, access information about the plurality of frequency band cells through a primary frequency band cell of the plurality of frequency band cells determined by considering the measurement result information; and
receiving, by the terminal, data channels through each of the plurality of frequency band cells based on the received access information,
wherein each of the data channels received through each of the plurality of frequency band cells is processed by a corresponding one of a plurality of entities of a Medium Access Control (MAC) layer,
wherein each of the plurality of entities respectively corresponds to each of the plurality of frequency band cells, and
wherein, when the terminal configures the MAC layer, the terminal sets the plurality of corresponding entities of the MAC layer to correspond to the plurality of frequency band cells.
