摘要：
The 5G band mainly adopts high frequency band with large bandwidth and high downlink rate, but poor penetration and high road loss, coupled with the fact that the power of the terminal is much less than the transmitting power of the base station, the problem of insufficient uplink coverage is becoming increasingly prominent. Three traditional uplink coverage enhancement techniques, as well as super uplink techniques using uplink Tx switching, are introduced in this paper, and the various schemes are analysed as advantages and disadvantages to provide some reference for network construction.
