Embodiment 1

[0075] The embodiment of the present invention improves on the basis of the existing literature, so that the power consumption optimization model can more accurately reflect the actual transmission power and power consumption of the base station, and on this basis, an improved SINR-based and pairing theory is proposed access strategy. Among them, the pairing theory is used to solve the load balancing problem caused by the change of the load quantity in the access process, and the Lagrangian dual and dichotomy method are used to optimize and adjust the resource ratio allocated to each user in the access process and the base station for each user. The transmit power provided.

Abstract

The invention provides a user access method based on energy consumption and pairing in an ultra-dense heterogeneous network system. The method comprises the steps as follows: a utility function valueof each base station on a user side to a user is computed according to an SINR value between the user and each base station, the user sends an access request to the base station having the highest utilization function value to itself, the SINR value extracted by the base station from the access request serves as the utility function value of the user for sending the access request on the base station side, the base station judges whether the user with the highest utility function value can access the bas station according to the rate request and interference condition of the user with the highest utility function value on the base station side, if yes, the information of successful access is fed back to the user with the highest utility function value; and otherwise, the information of failed access is fed back to the user with the highest utility function value. According to the invention, the user access algorithm under the ultra-dense deployment scene is provided, and the user access problem based on energy efficiency optimization under the given target rate condition is solved.

Description

technical field [0001] The invention relates to the technical field of wireless network communication, in particular to a user access method based on energy consumption and pairing in an ultra-dense heterogeneous network system. Background technique [0002] With the advancement of mobile communication technology, the widespread use of smart phones, the rapid development of mobile Internet, Internet of Things and various new services, the number of UEs (User Equipment, user terminals) and mobile data traffic have experienced explosive growth. Dense deployment of heterogeneous networks will become an inevitable trend in the future development of mobile communications. The ultra-dense deployment of small cells will inevitably lead to increased network energy consumption and unbalanced base station loads. The energy consumption of the base station is closely related to the number of loads associated with the base station, so a suitable user access algorithm plays an important ...
