Title: METHOD AND DEVICE FOR SPECTRUM SHARING
Abstract:
Provided in embodiments of the present invention are a method and device for spectrum sharing, for use in increasing utilization rate of spectrums. The method is such that: a first device determines a first power employed for transmitting a signal in a channel sharing phase on an unlicensed spectrum, where the channel sharing phase refers to the first device and at least one second device jointly occupy all channel resources on the unlicensed spectrum, and the first device employs the first power to transmit the signal in the channel sharing phase on the unlicensed spectrum. As such, by jointly occupying a resource with another device in the channel sharing stage, and adjusting the magnitude of the transmission power, under the premise that non-increase in the level of inter-device interference is ensured, the utilization rate of the spectrums and system capacity are greatly increased.
