Classification: CPC H | IPC H

Claim 6:
7. A terminal 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 terminal device to:
receive a first tracking reference signal from a first transmission reception apparatus of a single frequency network cell;
receive a second tracking reference signal from a second transmission reception apparatus of the single frequency network cell, wherein the first tracking reference signal and the second tracking reference signal occupy different time-frequency resources;
receive indication information from the first transmission reception apparatus or the second transmission reception apparatus, 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, and the downlink signal comprises a demodulation reference signal and downlink data;
determine based on the one or more tracking reference signals for receiving the downlink signal, a first carrier frequency on which the downlink signal is to be received;
receive the demodulation reference signal and the downlink data based on the first carrier frequency; and
demodulate the downlink data based on the demodulation signal.
