Problems solved by technology
The generalized edge coloring problem of a graph is an NP-complete problem, which means that the optimal solution of the problem cannot be obtained in polynomial time. In the case of a large number of transceivers and frequencies, I want to use the method of exhaustive search to obtain the problem The optimal solution of is not feasible in time

Embodiment Construction
[0031] by figure 1 Take the example shown as an example to illustrate the principle and process of forming a reverse auction group. For convenience of description, cells are numbered using C (representing Cell) plus Arabic numerals. When cell C7 is added to the network, the neighbor relationship between cell C7 and the original cell in the network must be obtained first according to the coverage setting of each cell in the network planning and the requirements of signal-to-interference ratio. Such as figure 1 As shown, the circle around the cell label indicates the signal coverage of this cell, so according to the overlapping situation, it can be seen that the original cell C2, C3, C5 and C6 are the neighbors of the newly added cell C7 district. Then after obtaining such a neighbor cell list, the newly added cell No. C7 will send a reverse auction request message to all its neighbor cells. After receiving the request message, if the neighbor cells are willing to contribute...

The invention relates to a method for distributing local carrier frequencies based on a reverse auction, in particular to a method for distributing carrier frequencies in a wireless communication technique. The method comprises the following steps of: establishing a model relevant to the carrier frequency distribution problem of a newly increased cell in a network; and distributing the carrier frequencies of the newly increased cell by adopting the method for distributing the local carrier frequencies based on the reverse auction. The method for distributing local carrier frequencies based onreverse auction is used for distributing local carrier frequencies based on a network topology. Under the condition of meeting interference conditions, the method realizes the purposes of improving the network capacity and the frequency utilization rate by improving the utilization rate of the carrier frequencies and reducing the influence on the original cell when used for distributing. The provided method for distributing local carrier frequencies meets the requirement on network planning and can solve problems within a smaller range. The provided method for distributing local carrier frequencies based on reverse auction has adaptability to the change of the network topology and strong universality.
Description
technical field [0001] The invention relates to a carrier frequency allocation method in wireless communication technology, in particular to a reverse auction-based local carrier frequency allocation method. Background technique [0002] The two main goals of wireless communication research are to maximize the utilization of radio frequency and minimize the impact of interference. In communication systems, radio frequency spectrum is a very important resource. However, in recent years, the development and utilization of spectrum resources has been far behind the rapid growth of spectrum demand in fields such as broadcasting, television, and mobile communications. People are also increasingly paying attention to this problem. Emerging wireless communication technologies, such as cognitive radio and cellular system multi-carrier frequency technology, all regard improving spectrum utilization as the most important goal. [0003] Due to the uneven distribution of the number of...
