METHOD OF ENABLING COMMUNICATION IN A SECOND COMMUNICATION CHANNEL THROUGH INTERMEDIATION IN A FIRST COMMUNICATION CHANNEL
A wireless relay communication apparatus communicates over a first and a second wireless communication channel, which are incompatible in at least one property, aspect, or parameter. A message indicating a capacity to act as a relay in the second communication channel is transmitted over the first or the second wireless communication channel. A transmission, received over the second communication channel from a source communication apparatus, includes information enabling the relay communication apparatus to determine that the transmission is to be relayed to a destination communication apparatus. Accordingly, the relay communication apparatus relays the transmission to the destination communication apparatus over the second communication channel. Alternatively, the relay communication apparatus listens in, on the first communication channel, on a negotiation between source and destination communication apparatus for an impending communication on the second communication channel, and relays received transmissions between the communication apparatus.
