Embodiment Construction

[0021] The network diagram of this embodiment is as follows figure 1 As shown, the access node selects a remote radio unit (RRH), and the system has M RRHs, K mobile users and a central processing unit. All RRHs are connected to the central processing unit through high-speed links (optical fibers, etc.), and wireless communication is performed between mobile users and RRHs. The RRH is only responsible for data transmission, not data processing. The data processing required in the technical method is carried out in the central processing unit. The required channel information in step S1 can be fed back to the RRH by each user, and then transmitted to the central processor, and then the central processor processes according to specific steps, and finally determines the RRH service set for each user, and transmits the information through optical fiber, etc. The high-speed link is transmitted to each RRH, and then sent to each user through a wireless channel.

Abstract

The present invention discloses a power allocation method of a virtual cell in a 5G high density network. The method includes a first step of initializing number of iterations i to be 0 and p<m, n, k> to be 0, and initializing a Lagrange multiplier; a second step of calculating an allocation power p<m, n, k> according to a Lagrange multiplier for iteration at present; a third step of making the number of iterations i i+1, and updating the Lagrange multiplier; and a fourth step of determining whether the Lagrange multiplier is converged, if yes, making an allocation power matrix obtained through calculation at present a final allocation power, if not, executing the second step. The method has lower complexity.

Description

technical field [0001] The present invention relates to the technical field of 5G communication, in particular to a power allocation method of a virtual cell in a 5G high-density network. Background technique [0002] Cell virtualization technology is one of the top ten wireless new technologies released by ZTE in 2015. This technology is the key to solving the boundary effect, and its core idea is to provide services "centered on users". For traditional base stations, it is unrealistic to continue to reduce the radius of outdoor deployment cells due to the high switching frequency and huge transmission overhead. [0003] "Virtual cell" breaks the traditional concept of mobile access network centered on "cellular cell" and transforms into a completely "user-centered" access network, that is, each user accessing the network has a user-related "Virtual Community". The virtual cell is composed of several access nodes around the user, and the access nodes cooperate with each ...
