Classification: CPC H | IPC H

Claim 15:
16. A user equipment, comprising:
a first receiver configured to receive data on a first frequency band;
a second receiver configured to receive, from a base station and on the 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 the detection signals are inserted within a whole band in frequency domain;
a processor configured to generate channel condition information about the second frequency band based on the received detection signal, wherein, the channel condition information about the second frequency band comprises channel line of sight (LOS)/no-line of sight (NLOS) information about the second frequency band, a receiving power of the detection signal and a signal interference noise ratio (SINR) of the detection signal; and
a transmitter configured to transmit the channel condition information about the second frequency band to the base station via the first frequency band.
