Abstract:
1. A process of demodulating information in a multi-carrier communications system, comprising: A. 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. 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. 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. filtering and demodulating the second and third received carrier signals to receive control information on a control channel; E. buffering the data channel of the first carrier signal until after demodulating control information in the control channel of the first carrier signal; F. determining at least one carrier frequency to be filtered and demodulated for data channel transmissions in response to the control information; and G. filtering and demodulating the at least one carrier frequency to receive data.
