    • Abstract
  • The 5G application scenarios such as remote control, high-definition video, unmanned mine car and unmanned aerial vehicle in intelligent mine put forward new requirements for the uplink rate of wireless network. However, the current 5G network uplink rate is insufficient, which leads to the limitation of intelligent mine business. And the existing 5G network uplink rate enhancement algorithm has limited range to improve the uplink rate. In order to solve the above problems, this paper proposes an uplink rate enhancement algorithm for 5G network in intelligent mine. By using supplementary upload technology, the spectrum resource aggregation is realized by overlaying Sub-3 GHz low band on the high band of C-Band, and the uplink rate of the network is improved by frequency domain resource allocation and time domain resource scheduling. In the middle-near point area, when the base station performs uplink data scheduling, the user equipment uses the 3.5 GHz frequency band to send uplink data in the uplink time slot of the C-Band frequency band, and uses the 1.8/2.1 GHz frequency band to send uplink data in the downlink time slot of the C-Band frequency band. In the far point area, the 3.5 GHz frequency band uplink is limited, and the user equipment only uses the 1.8/2.1 GHz frequency band to send uplink data. The test results show that the algorithm improves the mine near-point area, middle-point area and far-point area uplink rate by 17%, 41% and 213% respectively, and the average network uplink rate is significantly improved.
