Uplink reference signal transmission method and apparatus

A method, comprising:

• determining, by a high frequency base station, N time slices that are used to receive an uplink reference signal transmitted by a terminal in a single time slice of the terminal, wherein N is a positive integer greater than 1;
• and
• switching, by the high frequency base station, receive beams in different time slices in the N time slices to receive the uplink reference signal transmitted by the terminal in the single time slice of the terminal, wherein there is a guard interval at at least one end of the uplink reference signal.

An apparatus, comprising:

• a processor configured to determine a time domain resource sending position of an uplink reference signal of a terminal on a high frequency link, wherein there is a guard interval at at least one end of the uplink reference signal;
• and
• a transmitter configured to after arriving at the time domain resource sending position, switch transmit beams in different time slices in M time slices to transmit the uplink reference signal, wherein the uplink reference signal comprises uplink reference signals transmitted in the M different time slices, and M is a positive integer greater than 1.

An apparatus, comprising:

• a processor configured to determine N time slices that are used to receive an uplink reference signal transmitted by a terminal in a single time slice of the terminal, wherein N is a positive integer greater than 1;
• and
• a receiver configured to switch receive beams in different time slices in the N time slices to receive the uplink reference signal transmitted by the terminal in the single time slice of the terminal, wherein there is a guard interval at at least one end of the uplink reference signal.
