Classification: CPC H | IPC H

Claim 0:
1. A method for wireless communication, comprising:
transmitting data on a first frequency band;
transmitting, on a second frequency band, a detection signal for detecting a channel condition of the second frequency band, wherein the detection signal has a frame format in which: each detection signal is provided at intervals of 200 ms and contains 1 detection frame and 19 normal frames; each detection frame is of 10 ms and contains 10 sub-frames; each sub-frame is of 1 ms and contains 4 slots; each slot contains 14 OFDM symbols; each detection signal occupies 8 OFDM symbols in each slot in time domain, and all of detection signals are inserted within a whole band in frequency domain;
generating channel condition information about the second frequency band based on a received detection signal;
feeding back the channel condition information via the first frequency band; and
selecting a current data transmission frequency band based at least in part on feedback channel condition information about the second frequency band and/or traffic requirement information,
wherein the current data transmission frequency band is any one of the first frequency band, the second frequency band or a cooperative transmission of the first frequency band with the second frequency band.
