Terminal association and power distribution method and device and storage medium

Abstract

The invention discloses a terminal association and power distribution method. The method comprises the following steps: acquiring wireless node information and terminal information; wherein the wireless nodes comprise a first wireless node and a second wireless node; determining the downlink capacity of an access link and the downlink capacity of a return link based on the wireless node information and the terminal information; determining the transmission power and the terminal association according to a first model on the basis of the downlink capacity of the access link and the downlink capacity of the backhaul link under the condition of meeting a first constraint condition that the related parameters of the second wireless node and the transmission power of the second wireless node tothe terminal are satisfied; wherein the terminal association is an association relationship between the terminal and the wireless node. The invention also discloses two terminal association and powerdistribution devices and a storage medium.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method, device and storage medium for terminal association and power distribution. Background technique [0002] With the fifth generation (5 th With the development and advancement of mobile communication technology (Generation, 5G), the number of devices connected to the network has increased sharply, and new services have continued to emerge, putting unprecedented new requirements on bandwidth, delay, and network interactivity. The International Telecommunication Union pointed out that the goal of 5G mobile communication systems and future communication systems is to provide 1000 times higher network capacity, 100 times higher energy efficiency and 10 times lower time delay than 4G mobile communication systems. [0003] In order to achieve the above goals and deal with the challenge of data transmission, it is necessary to deploy a large number of small cells (SmallCell),...

Problems solved by technology

[0004] In related technologies, in this deployment structure, the terminal judges which base station to access according to the strength of the received signal, that is, the user judges the connection relationship (user association) with the base station according to the signal strength; however, due to the transmit power of the macro base station The transmission power of the small cell base station is higher than that of the small cell base station, so there are too many users accessing the macro base station, which causes the problem of unbalanced load

Moreover, in practical applications, when establishing user association, it is also necessary to consider the limitation of link capacity. For this problem, there is currently no effective solution
