Abstract
A radio apparatus () notifies a radio apparatus () of a new reverse channel to be used in a reverse link () and another idle reverse channel(s). If reachability of a forward link () is lost by the use of a new forward channel associated with the new reverse channel, the radio apparatus () determines a further new forward channel from among forward channel(s) associated with the idle reverse channel(s) of which the radio apparatus () has been notified by the radio apparatus (). This contributes, for example, to a safe switch of the bidirectional operating radio channels without using a redundant connection, when frequency-division multiplexing with fixed frequency spacing is used.
