Method and apparatus for band transfer in multiband communication system

摘要

A method and apparatus for transferring to a second communication band and returning to an original communication band according to a channel state in a multiband communication system are provided. The method includes communicating with a peer device in a first band, determining a channel state of a second band, and transferring to the second band based on a result of the determination, thereby efficiently using a plurality of bands and thus improving a data transmission speed.

1. A communication method of a multiband communication device, the method comprising:
communicating with a peer device in a first communication band; determining a channel state of a second communication band; and transferring to the second communication band based on a result of the determining, wherein the communication device enters an active mode during a predetermined period at predefined intervals in the second communication band to determine the channel state of the second communication band and transmit the channel state of the second communication band to the peer device, and operates in a power-saving mode during times other than the predetermined period in the second communication band.
