Mass node access resource allocation method and device, terminal and storage medium

Abstract

The invention discloses a massive node access resource allocation method and device, a terminal and a storage medium, and the method comprises the steps: obtaining an uplink signal of each terminal node, and calculating a correction distance of each terminal node according to the uplink signal of each terminal node and a distance estimation error of a reference point; calculating a corresponding Rician K factor according to the uplink signal of each terminal node; and grouping the terminal nodes according to the correction distances of the terminal nodes and the corresponding Rician K factors, and allocating communication resources to the terminal nodes according to the grouped sequence. According to the invention, the distance of each terminal node is pre-estimated through the uplink signal sent by each terminal node, the corresponding Rician K factor is calculated according to the uplink signal, and correlation calculation can be carried out according to the position distribution characteristic and the channel characteristic of each terminal node, so that grouping and resource allocation can be carried out on each terminal node quickly, and the user experience is improved. Under the condition that massive nodes are accessed at the same time, a rapid and reasonable distribution process of communication resources is realized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device, terminal and storage medium for allocating access resources of massive nodes. Background technique [0002] Marine situational awareness based on wireless sensor networks is an emerging modern marine environment monitoring technology, which has been highly valued and fully utilized by major maritime countries in recent years. and information release system to realize remote, real-time and normalized monitoring of marine environmental information, and to apply marine environmental information to coastal meteorological early warning, fishery production, marine scientific research and other fields. The marine environment has the characteristics of harsh natural environment, wide monitoring range, and poor infrastructure. It is necessary to meet the requirements of stable system operation, low power consumption, long-distance transmission, low cost, a...
