In order to improve the transmission stability of the 5G communication downlink channel and the control effect of the transmission control system,a 5G communication downlink channel transmission control system based on the aggregation level is designed and developed.The DSP co-processor,the communication data collector and the channel transmission controller are modified to complete the optimization of the hardware system.According to the spatial structure and working principle of the channel,the communication downlink channel model is constructed and the real-time status of the communication downlink channel is determined.By using this model,the real-time transmission data of the communication downlink channel is collected,and the channel transmission resources are allocated according to the aggregation level of the channel.Finally,the transmission control function of the system is realized from the aspects of channel enhancement,sending/receiving end,transmission interference and transmission speed.Through the system test experiments,it is concluded that the average transmission rate control error of the designed system is 4.6 MB/s,the average packet loss in the channel transmission is 0.024 GB,and the average channel congestion probability is 30.69%,all of which are reduced.The designed system has more advantages in the transmission control function.
