    摘要： Method and apparatus for combining high data rate traffic and low data rate traffic on a common transmission medium while maximizing efficient use of available spectrum. Since spectrum is an economically valuable resource and transport of data generates revenue, the present invention directly leads to more profitable network operation. The disclosed systems are applicable to both wired and wireless transmission media. In one embodiment, a bandwidth reservation scheme provides that data rate may be varied so that when a particular data communication device is allocated a frame, it is also assigned a data rate for use in that frame. Because bandwidth usage varies with data rate, the division of available spectrum into channels for use by individual data communication devices may also vary among frames.

    摘要： A medium access contention protocol that is highly beneficial in wireless networks and particularly in wireless networks that employ a fixed minimum burst size such as OFDM wireless networks. In one embodiment, a MAC protocol is a demand-assigned protocol that maximizes utilization of the bus medium (the allocated frequency spectrum.) Each data communication device (DCD) in the network communicates with a central access point (AP). Multiple DCDs may request access from the AP in the same request access (RA) burst. Each of the multiple DCDs transmits its access request to the AP within a frequency domain channel in the RA burst that is orthogonal to the frequency domain channels used by the other DCDs requesting access. Each DCD includes channel training information in the access request burst to allow the AP and/or DCD to adapt to rapid variations in channel characteristics.

    摘要： A distributed microcellular communication system comprised of a plurality of subcells arranged within one or more conventional cells. The distributed microcellular communications system includes one or more remote site stations, each of which transmits and receives information signals over an assigned set of communications channels within an associated subcell. Each remote site station includes a wideband RF receiver network within which information signals received from mobile units are converted into reverse link digital information signals. Also disposed within each remote site station is a remote communications link transceiver for transmitting the reverse link digital information signals over a communications link to the central base station, as well as for receiving forward link digital information signals from the central base station. The central base station includes a central communications link transceiver for receiving the reverse link digital information signals delivered over the communications link, as well as for transmitting the forward link digital information signals. The central base station is disposed to process the call information inherent within the forward and reverse link digital information signals in the manner required by standard cellular protocols. In an alternate implementation the remote site station further includes a channelizer for selecting a set of the reverse link digital information signals corresponding to the assigned set of communications channels, and may also include a bank of demodulator for demodulating the set of reverse link digital information signals.
