Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] see figure 1 As shown, an embodiment of the present invention provides a method for wireless power cloudification based on a large-scale antenna array, and the method includes the following steps:

[0040] Step S1, create an idle energy factor E idle , used to represent the factor that contains the remaining power in the unit frequency; when the free energy factor E idle When applied to a large-scale antenna array, the formula for defining the idle energy factor of each antenna in a large-scale antenna array is: Among them, P i , P' i Respectively represent the maximum effective transmit power and the allocated power of the i-th (i is a positive integer) antenna in the antenna resource pool, and the difference between the two is the remaining power of the antenna; SNR i Indicates the signal-to-noise ratio of the antenna; ...

Abstract

The invention discloses a wireless power cloudization method and system based on a large-scale antenna array and relates to the technical field of wireless communication. The method comprises the steps that an idle energy factor is established and a calculation formula of the idle energy factors of antennas in the large-scale antenna array is defined; the antennas in the large-scale antenna arrayupload state information to a cloud server; the cloud server calculates the idle energy factor of each antenna according to the state information and selects and adds the appointed number of antennasto an antenna resource pool; the cloud server dynamically selects the antennas capable of being occupied according to a scheduling algorithm based on the idle energy factors; and the antennas capableof being occupied are registered in the cloud server, the cloud server allocates power resources to the registered antennas according to use demands until the antennas are used completely, and then the power resources are released. According to the method and the system, the cloudization of a wireless network power domain is realized, and the contradiction between the continuous increase of the number of various kinds of business and the shortage of non-renewable resources in a network is effectively solved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and system for wireless power cloudification based on a large-scale antenna array. Background technique [0002] 5G (fifth generation mobile communication technology) expands the application scope of network information from the current "human-network" communication to "human-network-thing" collaborative communication, ultra-dense connection Internet of Things, Internet of Vehicles and industrial Internet, etc. broad field. In the next 5 to 10 years, the long-term development direction of network and communication technology is the Internet of Everything, and the number of connections will grow from tens of billions to hundreds of billions. Therefore, NB-IoT for low-power consumption and ultra-large link applications is expected to become a network infrastructure with large-scale coverage. [0003] In the 5G era, there are many resources in the w...
