[0004] Recently, many scholars have studied the allocation of these two resources separately, but they have not considered the simultaneous sharing and allocation of the two resources in the hybrid power supply mode.
At present, in the information that has been consulted, there is still no precedent for ensuring the communication rate requirements of mobile devices and joint resource allocation in a cooperative cellular network under a hybrid power supply mode.

The invention discloses a combined resource cooperative distribution method in a cellular network under a hybrid power supply mode and belongs to the technical field of wireless communication. According to the method, the cellular network under the hybrid power supply mode is established, the cellular network comprises two cellular systems, and each cellular system is provided with a base station. The two cellular systems share the same segment of a frequency spectrum such that the phenomenon that a certain cellular system has tensed frequency spectrum resources yet the other cellular system has excess frequency spectrum resources can be avoided, and the frequency spectrum utilization rate is greatly improved. Under the hybrid power supply mode, by use of a conventional power network power supply method, the stability of a whole network system is guaranteed, and at the same time, the cost of the whole system is decreased by use of renewable energy for power supply. Besides, when renewable energy collected by a certain cellular system is excessive yet renewable energy collected by the other cellular system is not sufficient, at the moment, the cellular system with the excessive renewable energy shares a part of the energy with the other cellular system, and thus the cost of the whole cellular network is further decreased.
Description
technical field [0001] The invention relates to a joint resource cooperative allocation method in a cooperative cellular network under a hybrid power supply mode, and belongs to the technical field of wireless communication. Background technique [0002] In recent years, with the rapid development of communication technology, the number of wireless mobile devices has also increased significantly, and the energy consumption of cellular systems has also increased significantly. In a traditional cellular network, the energy required for its operation is purchased from the grid. In order to save costs, people have begun to turn their attention to renewable energy, such as solar energy, wind energy and other renewable energy, and use this to supplement the use of traditional energy in the energy consumption of base stations. In some communication systems with energy harvesting functions, many scholars have begun to study the energy cooperation between base stations in hybrid pow...
