Abstract
A wireless RF data transmission system has at least one base station transmitting control information on a control channel and high speed data on at least one data channel. At least one subscriber station receives the control information and data channels, adjusting a modulation and/or coding of reception of the data in response to the control information. Preferably, the control information is transmitted using a more robust modulation, such as QPSK, than used to transmit the data, which is preferably transmitted using either 16, 64 or 256 QAM. Additionally, timing or header information for the data may be included on the control channel.
