Claim 14:
15. A communications device comprising:
a transceiver;
at least one processor; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to cause the communications device to:
send of a single frequency network cell, a first tracking reference signal to a terminal device through a first transmission reception apparatus;
send a second tracking reference signal to the terminal device through a second transmission reception apparatus, wherein the first tracking reference signal and the second tracking reference signal occupy different time-frequency resources; and
send indication information to the terminal device, wherein the indication information indicates one or more tracking reference signals for receiving a downlink signal, the one or more tracking reference signals for receiving the downlink signal are at least one of the first tracking reference signal and the second tracking reference signal, the downlink signal comprises a demodulation reference signal and downlink data, and the demodulation reference signal is for demodulating the downlink data.
