Embodiment 1

[0123] Such as figure 1 shown.

[0124] A method for resource allocation and energy management of a cooperative cellular network, implemented by the following system: the system includes two cellular networks, each cellular network includes a base station and K i users, where i is the base station number, K i Indicates that there are K in base station i i user, user gather and respectively represent the sets of users in the two base stations; the two base stations share the same spectrum, and divide the entire licensed frequency band into N subcarriers with the same bandwidth, and the bandwidth of each subcarrier is B; let x i,k,n Assignment factors for subcarriers, where n represents the nth subcarrier, set of subcarriers When subcarrier n is assigned to the kth user in base station i, x i,k,n = 1; otherwise, x i,k,n = 0, and each subcarrier can only be assigned to one user; the channel gain of the kth user in base station i on the nth subcarrier is expressed ...

Embodiment 2

[0215] The method for resource allocation and energy management of a cooperative cellular network as described in Embodiment 1 is different in that the user is a single-antenna user; and the subcarrier is an orthogonal narrowband subcarrier.

Embodiment 3

[0217] As in the resource allocation and energy management method of the cooperative cellular network described in Embodiment 1, the difference is that the method of dividing the entire authorized frequency band into N subcarriers with the same bandwidth is to adopt the orthogonal frequency division multiplexing modulation technology The entire authorized frequency band is equally divided into N subcarriers with the same bandwidth.

Abstract

The invention relates to a resource allocation and energy management method of a collaborative cellular network. The resource allocation and energy management method ensures communication quality of each user through satisfying the minimum communication rate of each user, can maximize a sum of costs of two collaborative communication networks, and can guarantee the communication rate requirement of each user.

Description

technical field [0001] The invention relates to a resource allocation and energy management method of a cooperative cellular network, belonging to the technical field of wireless communication. Background technique [0002] The rapid development of wireless communication technology has developed to 5G technology. The rapid development of technology has made the communication rate and communication quality better and better. At the same time, the number of wireless devices has also increased rapidly, and the energy consumption of the entire network system has also increased significantly. In response to the concept of green communication, scientific research scholars began to turn their attention to renewable energy to replace some traditional electric energy, such as solar energy, wind energy and other renewable energy sources. This approach is not only in line with the concept of sustainable development and green communication, but also, the price of renewable energy is lo...
