The invention discloses a resource allocation method of a 5G communication system based on a predatory search algorithm. The method comprises the following steps: firstly, initializing system parameters comprising related parameters of a channel and a mobile terminal, and control parameters of the predatory search algorithm; then encoding resource allocation schemes of the system, randomly selecting an initial point in the possible resource allocation schemes, and initializing a limit set, and finding an optimal solution of resource allocation based on the predatory search algorithm with the maximum channel capacity value as the objective; and finally carrying out channel resource allocation according to the allocation scheme corresponding to the optimal solution. By adoption of the resource allocation method disclosed by the invention, resource allocation optimization can be carried out quickly and effectively, and the network capacity is effectively improved.
Description
technical field [0001] The invention relates to the field of 5G communication, and relates to a resource allocation method of a 5G communication system based on a predatory search algorithm. Background technique [0002] In a traditional cellular mobile communication network, if two device users need to communicate, they must be transferred through the base station, that is, the transmitting end first sends the information to be sent to the base station, and then the base station sends the information to the receiving end. The required spectrum resources and channels are allocated by the base station. Although this centralized communication method is convenient for the management and control of wireless spectrum resources and interference, the resource utilization rate is low. Communication, this will be a waste of spectrum resources. At the same time, with the rapid growth of data demand, the 5G mobile communication network is forced to greatly increase its network throug...
