Abstract:
1. A multi-carrier communications system comprising: A. first RF and baseband means receiving a first carrier signal at a first carrier frequency for a first time period, the first carrier signal providing compatibility with a legacy communications system, the receiving a first carrier signal including receiving a multiplexed control channel with a data channel; B. second RF and baseband means receiving a second carrier signal at a second carrier frequency different from the first carrier frequency, the receiving a second carrier signal including receiving a control channel at a time period prior to the first time period and receiving a data channel at a time period the same as the first time period; C. third RF and baseband means receiving a third carrier signal at a third carrier frequency different from the first and second carrier frequencies, the receiving a third carrier signal including receiving a control channel at a time period prior to the first time period and receiving a data channel at a time period the same as the first time period; D. the second and third RF and baseband means filtering and demodulating the second and third received carrier signals to receive control information on a control channel; and E. the first RF and baseband means buffering the data channel of the first carrier signal until after demodulating control information in the control channel of the first carrier signal.
