Abstract

Communication methods and devices are provided. A communication method includes: a first communication device detecting whether its communications is substantially affected; and if yes, sending a message to a second communication device, whose communication distance is shorter than that of the first communication device, to request the second communication device to decrease its effect on the communications of the first communication device. More reliable solutions for spectrum sharing may be obtained.

Description

technical field [0001] The present invention generally relates to spectrum sharing. Background technique [0002] Recent demands for more efficient use of wireless communication resources have revealed more scenarios for spectrum sharing. In a conventional spectrum sharing scenario, primary users communicate with each other in a first frequency band based on a first communication technology, and secondary users communicate with each other in a second frequency band based on a second communication technology, wherein the first frequency band and the second frequency band are part of each other overlapping. For the safe communication of primary users, secondary users will reduce their transmission power once they perceive the presence of primary users. Contents of the invention [0003] In one embodiment, a communication method is provided, the method may include: a first communication device detecting whether its communication is substantially affected; and if so, sending...
