Method for transmitting reference signal, method for receiving reference signal, base station and user equipment

A method for receiving a reference signal, performed by a user equipment (UE), comprising:

• receiving the reference signal sent by a base station;
• detecting a setting signal in the reference signal to determine a position where the setting signal is located, wherein the setting signal is used to determine an index of the reference signal;
• acquiring a signal set during a preset time interval according to the position where the setting signal is located;
• determining location information corresponding to the reference signal according to the signal set;
• and
• determining the index of the reference signal according to the location information, and performing time domain synchronization with the base station according to the index;
• wherein the reference signal comprises a synchronization signal block (SSB), and the setting signal comprises PBCH in the SSB;
• wherein indexes of the reference signal corresponding to the plurality of possible transmission positions are the same;
• wherein the method further comprises:
• determining a signal in the reference signal as the setting signal;
• or
• determining different signals in the reference signal as the setting signal according to a transmission frequency point or a subcarrier interval of the reference signal.

A user equipment, comprising:

• at least one processor;
• and
• a memory, for storing instructions executable by the at least one processor;
• wherein the at least one processor is configured to:
• receive a reference signal sent by a base station;
• detect a setting signal in the reference signal to determine a position where the setting signal is located, wherein the setting signal is used to determine an index of the reference signal;
• acquire a signal set during a preset time interval according to the position where the setting signal is located;
• determine location information corresponding to the reference signal according to the signal set;
• and
• determine the index of the reference signal according to the location information, and perform time domain synchronization with the base station according to the index;
• wherein the reference signal comprises a synchronization signal block (SSB), and the setting signal comprises PBCH in the SSB;
• wherein indexes of the reference signal corresponding to the plurality of possible transmission positions are the same;
• wherein the at least one processor is further configured to:
• determine a signal in the reference signal as the setting signal;
• or
• determine different signals in the reference signal as the setting signal according to a transmission frequency point or a subcarrier interval of the reference signal.
