The invention provides a channel distribution method and equipment thereof. A communication system comprises a first base station and a second base station which use the same frequency; a sector covered by the first base station comprises an interference area interfered by the same frequency of the second base station; and a channel shared by the first and the second base stations is divided into a plurality of sub-channels. The method comprises: receiving synergistic information sent by the second base station, and using the synergistic information to negotiate the using information for the plurality of sub-channels in the interference area; and according to the synergistic information, confirming the use of the sub-channels by the first base station in the interference area. The equipment comprises a receiving unit and a first confirming unit. By adopting the provided method and equipment, the sub-channels can be used in a dynamic way in the interference area, so that the situation that the same sun-channel is occupied by a plurality of base stations in the interference area at the same time, the utilization rate of the sub-channels is improved, and the frequency spectrum efficiency is increased.
Description
technical field [0001] The present invention relates to the communication field, in particular, to a method and device for allocating channels in the communication field. Background technique [0002] When using spectrum resources, which are scarce resources in a communication system, they cannot be used arbitrarily, but must comply with certain spectrum regulations. Due to the limitation of available spectrum resources, today's communication systems can only use limited frequency points and transmit within a limited bandwidth. In order to improve spectrum efficiency, a single-frequency point networking solution is often adopted. When a single frequency point is used for networking, the edge areas of adjacent cells or sectors overlap. Since the same spectrum resource is used in the edge area, very serious interference will be generated, which will greatly affect the communication quality of the edge area. . [0003] Taking the WiMAX (Worldwide Interoperability for Microwa...
