Uplink Reference Signal Transmission Method and Apparatus

A method, comprising:

• determining, by a high frequency base station, N time slices in a first interval for receiving an uplink reference signal a first time and N time slices in a second interval for receiving the uplink reference signal a second time, wherein N is a positive integer greater than 1;
• and
• receiving the uplink reference signal the first time in the first interval and the second time in the second interval, wherein in the first interval the high frequency base station sequentially switches a current receive beam used to receive the uplink reference signal according to a first sequence to use a different receive beam of the high frequency base station in each different time slice of the N time slices of the first interval, and wherein in the second interval the high frequency base station sequentially switches the current receive beam used to receive the uplink reference signal according to a second sequence to use a different receive beam of the high frequency base station in each different time slice of the N time slices of the second interval, wherein the uplink reference signal received the first time in the first interval is transmitted by a terminal in a first single time slice of the terminal, the uplink reference signal received the second time in the second interval is transmitted by the terminal in a second single time slice of the terminal, and wherein a guard interval is located at a first end of the uplink reference signal.
