Abstract:
A signal sending and demodulation method, a device, and a system are provided, relate to the field of communications technologies, and can resolve a prior-art problem of a low user throughput caused by mismatch between poor PDCCH signal demodulation performance and PDSCH signal demodulation performance. A specific solution is as follows: A base station of a serving cell obtains a first power ratio restriction set preset by a base station of at least one interfering cell; sends a preset second power ratio restriction set and the first power ratio restriction set to a terminal; and sends a second original PDCCH signal to the terminal, where a current value of a second power ratio of the second original PDCCH signal is an element selected from the second power ratio restriction set. Embodiments of the present invention are used for signal demodulation.

Claim (Index 4):
A signal demodulation method, wherein the method comprises:\n receiving, by a terminal, a first power ratio restriction set preset by a base station of at least one interfering cell and sent by a base station of a serving cell and a second power ratio restriction set preset by the base station of the serving cell and sent by the base station of the serving cell, wherein an element in the first power ratio restriction set is a preset value of a first power ratio, the first power ratio is a ratio between a power of a first original control signal and a power of a first original pilot signal in a first original physical downlink control channel PDCCH signal sent by the base station of the interfering cell by using a first transmission channel, an element in the second power ratio restriction set is a preset value of a second power ratio, the second power ratio is a ratio between a power of a second original control signal and a power of a second original pilot signal in a second original PDCCH signal sent by the base station of the serving cell by using a second transmission channel; receiving, by the terminal, a PDCCH signal, wherein the PDCCH signal comprises a second PDCCH signal that is transmitted to the terminal by using the second transmission channel and originated from the second original PDCCH signal sent by the base station of the serving cell and a first PDCCH signal that is transmitted to the terminal by using the first transmission channel and originated from the first original PDCCH signal sent by the base station of the interfering cell; and demodulating, by the terminal, the PDCCH signal according to the first power ratio restriction set and the second power ratio restriction set, to obtain the second original PDCCH signal.
