Abstract

A method and apparatus for multiplexing a plurality of communication signals where the communication signals may operate using different protocols is provided. A communication node ( 102 ) that is a part of a communications system or network ( 100 ) is provided. The access point includes a transceiver ( 202, 204 ) for transmitting and receiving a first signal and a second signal wherein the first signal ( 410 ) is using a first protocol and the second signal ( 412 ) using a second protocol. The access point also includes a scheduler ( 208 ) for scheduling a transmit time for the first signal and for the second signal within a first frame ( 402, 404 ) and a receiving time for the first signal and for the second signal within a second frame ( 406, 408 ). A multiplexer ( 210 ) is also provided where the multiplexer combines the first signal and second signal in the first and second frames according to the scheduled transmit time and receive time.
