A method for configuring a resource of a downlink measurement reference signal, performed by a base station and comprising: determining, configuration information of a resource pool based on a preset basic pattern or preset available resources, wherein the resource pool comprises at least one resource that can be used to transmit the downlink measurement reference signal, the basic pattern comprises at least one basic elements, and the basic element comprises two resource elements that are adjacent in a time domain direction or a frequency domain direction; and sending, higher layer signaling or physical layer signaling to indicate the configuration information of the resource pool to a terminal device, wherein after the determining, configuration information of a resource pool, the method further comprises: determining, the resource pool based on the basic pattern and the configuration information; wherein the configuration information comprises a target multiple and a deviation value, wherein the target multiple is an integer not equal to 0, and the deviation value is an integer not equal to 0; and the determining, the resource pool based on the basic pattern and the configuration information comprises: extending, resources in the basic pattern in the time domain direction or the frequency domain direction by the target multiple, to obtain a basic resource pool; and enabling, the basic resource pool to deviate in the time domain direction and/or the frequency domain direction based on the deviation value, to obtain the resource pool. determining, configuration information of a resource pool based on a preset basic pattern or preset available resources, wherein the resource pool comprises at least one resource that can be used to transmit the downlink measurement reference signal, the basic pattern comprises at least one basic elements, and the basic element comprises two resource elements that are adjacent in a time domain direction or a frequency domain direction; and sending, higher layer signaling or physical layer signaling to indicate the configuration information of the resource pool to a terminal device, wherein after the determining, configuration information of a resource pool, the method further comprises: determining, the resource pool based on the basic pattern and the configuration information; wherein the configuration information comprises a target multiple and a deviation value, wherein the target multiple is an integer not equal to 0, and the deviation value is an integer not equal to 0; and the determining, the resource pool based on the basic pattern and the configuration information comprises: determining, the resource pool based on the basic pattern and the configuration information; wherein the configuration information comprises a target multiple and a deviation value, wherein the target multiple is an integer not equal to 0, and the deviation value is an integer not equal to 0; and the determining, the resource pool based on the basic pattern and the configuration information comprises: extending, resources in the basic pattern in the time domain direction or the frequency domain direction by the target multiple, to obtain a basic resource pool; and enabling, the basic resource pool to deviate in the time domain direction and/or the frequency domain direction based on the deviation value, to obtain the resource pool.
