1. A multi-band communication method, comprising:
before sending data frames in a plurality of frequency bands, respectively determining, by an access point, request to send (RTS) frames that are in a preset format and correspond to each frequency band; and
sending, by the access point, the RTS frames corresponding to each frequency band to a station;
wherein respectively determining, for the plurality of frequency bands, the request to send (RTS) frames that are in the preset format and correspond to each frequency band, comprises:
setting transmitter addresses of each frequency band that are different from each other and receiver addresses of each frequency band that are same with each other in the RTS frames that are in the preset format and correspond to each frequency band;
wherein setting the transmitter addresses that are different from each other comprises:
randomly generating the transmitter addresses that are different from each other in the RTS frames corresponding to each frequency band.
