Abstract
A method and device for obtaining carrier information and carrier information indication include: a user equipment obtains parameters of uplink carrier information according to the message sent by a network side in broadcast manner, or, the user equipment obtains parameters of uplink carrier information according to the preset information. Time Division Duplex wireless communication system with asymmetry uplink frequency band and downlink frequency band can be supported effectively, guard frequency band near the intersection occurred when the adjacent frequencies coexist is utilized fully, and frequency spectrum utilization rate is improved; further more, Time Division Duplex wireless communication system with unequal uplink band width and downlink band width can be supported, and the application of the Time Division Duplex system is expanded effectively.
