Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] The present invention provides a method for switching mobile perception cooperative multipoint transmission in a heterogeneous ultra-dense network. The heterogeneous ultra-dense network of the present invention adopts a two-layer UDN architecture, and the two-layer UDN architecture includes Macro BS for wide coverage and small BS for high bandwidth; according to m and lambda s Two independent uniform Poisson point processes (PPP) are used to deploy macro BSs and small BSs, where BSs located in different levels are heterogeneous in terms of transmission power and deployment density, while BSs located in the same level have the same transmission power. According to the characteristics of PPP, adding two independent homogeneous PPPs is still PPP, so the deployment density of all BSs can be expressed as λ m and lambda s the addition of.

Abstract

The invention provides a switching method for mobile sensing coordinated multi-point transmission in a heterogeneous ultra-dense network. The method comprises the following steps of: 1, establishing afinal coordinated BS set in all base stations BS connected with a user MD according to the distance between the user MD and the base stations BS and the estimated residence time of the user MD; and 2, in the final cooperative BS set established in the step 1, selecting triggering time of switching the base station BS by the user MD. According to the technology, a balance between the BS having a long residence time and the currently best performing BS for collaborative BS set determination is achieved; a large number of simulations show that the performance of the proposed MACH is superior tothat of the existing scheme in the aspects of coverage probability and switching probability.

Description

technical field [0001] The invention belongs to the field of the industrial internet of things, and in particular relates to a handover method of mobile perception coordinated multi-point transmission in a heterogeneous ultra-dense network. Background technique [0002] Ultra-dense networking (UDN) is considered to be one of the most promising network technologies for 5G wireless networks. By densely deploying base stations (BSs) on heterogeneous network layers (i.e., micro base stations, pico base stations, femto base stations, and remote radio heads), UDN provides a large number of flexible mobility for mobile users with high bandwidth and improved spectral efficiency. Access options. In the current wireless network, in the coverage area of ​​the macro base station, the deployment density of various low-power nodes of various wireless transmission technologies has been greatly increased compared with the previous deployment density. Even in the future, the ratio of the n...
