A communication method, applied to a first communication node, comprising: determining a radio resource for a second communication node to send a reference signal; and receiving the reference signal sent by the second communication node using the radio resource, wherein the radio resource comprises a time domain resource; and characterized in that determining the radio resource for the second communication node to send the reference signal comprises: determining, by the first communication node, the time domain resource according to following parameters: a period of the reference signal, and a slot offset of the reference signal, wherein in response to the period of the reference signal is 1, the slot offset of the reference signal is empty; in response to the period of the reference signal is 4, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 3; in response to the period of the reference signal is 8, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 7; in response to the period of the reference signal is 16, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 15; in response to the period of the reference signal is 32, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 31; and in response to the period of the reference signal is 64, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 63. determining a radio resource for a second communication node to send a reference signal; and receiving the reference signal sent by the second communication node using the radio resource, wherein the radio resource comprises a time domain resource; and characterized in that determining the radio resource for the second communication node to send the reference signal comprises: determining, by the first communication node, the time domain resource according to following parameters: a period of the reference signal, and a slot offset of the reference signal, wherein in response to the period of the reference signal is 1, the slot offset of the reference signal is empty; in response to the period of the reference signal is 4, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 3; in response to the period of the reference signal is 8, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 7; in response to the period of the reference signal is 16, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 15; in response to the period of the reference signal is 32, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 31; and in response to the period of the reference signal is 64, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 63. in response to the period of the reference signal is 1, the slot offset of the reference signal is empty; in response to the period of the reference signal is 4, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 3; in response to the period of the reference signal is 8, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 7; in response to the period of the reference signal is 16, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 15; in response to the period of the reference signal is 32, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 31; and in response to the period of the reference signal is 64, the slot offset of the reference signal is an integer greater than or equal to 0 and less than or equal to 63.
