Signal processing method and device

A signal processing device, comprising:

• a processor;
• memory coupled to the processor, the memory comprising instructions that, when executed by the processor, cause the signal processing device to:
• send a first data signal and receive a second data signal in a first resource block (RB) of a time unit,
• send a first reference signal according to first reference information and receive a second reference signal according to second reference information in the first RB, wherein the first reference signal is for demodulating the first data signal, the second reference signal is for demodulating the second data signal, and the first reference information is different from the second reference information, and
• demodulate the second data signal according to the second reference signal;
• wherein the first reference information comprises:
• a time-frequency resource location occupied by the first reference signal, and sequence information of the first reference signal;
• and
• wherein the second reference information comprises:
• a time-frequency resource location occupied by the second reference signal, and sequence information of the second reference signal.

A signal processing device, comprising:

• a transceiver, configured to:
• send a first data signal and receive a second data signal in a first resource block (RB) of a time unit, and
• send a first reference signal according to first reference information and receive a second reference signal according to second reference information in the first RB, wherein the first reference signal is for demodulating the first data signal, the second reference signal is for demodulating the second data signal, and the first reference information is different from the second reference information;
• a processor, configured to demodulate the second data signal according to the second reference signal received by the transceiver;
• wherein the first reference information comprises:
• a time-frequency resource location occupied by the first reference signal, and sequence information of the first reference signal;
• and
• wherein the second reference information comprises:
• a time-frequency resource location occupied by the second reference signal, and sequence information of the second reference signal.
