Dynamic frame size adjustment and selective reject on a multi-link channel to improve effective throughput and bit error rate

A method for providing wireless communication of digital signals, the digital signals being communicated between a plurality of wireless subscriber units and a base station, the digital signals being communicated using at least one radio frequency channel via Code Division Multiple Access (CDMA) modulated radio signals, the digital signals also having a given nominal data rate, the method comprising the steps of:

• (a) making available a plurality of subchannels within each CDMA radio channel, wherein a data rate of each subchannel is less than the nominal data rate of the digital signals;
• (b) establishing a network layer session between terminal equipment connected to a subscriber unit through the base station to other terminal equipment connected to the base station;
• and
• (c) during the network layer session, allocating available subchannels on an as-needed basis, with the number of subchannels allocated thereby changing during the duration of a given session;
• and
• (d) dividing a network layer frame into subframes according to optimum subframe sizes for each subchannel.

A data communication system comprising:

• a first multichannel transceiver to transmit data of a frame structure over one or more communication channels;
• a second multichannel transceiver to receive the data of a frame structure over the one or more communication channels;
• a first protocol converter connected to the first multichannel transceiver to divide a frame into subframes in an optimum subframe size;
• and
• a second protocol converter connected to the second multichannel transceiver to reassemble the subframes transmitted by the first multichannel transceiver and received by the second multichannel transceiver into the frame, to determine the number of subframes received in error at the second multichannel transceiver by counting the number of selective reject orders made to the first protocol converter, to determine the optimum subframe size for each communication channel based upon a determined number of subframes received in error which were attempted to be communicated over each channel, and to determine an error rate in each channel and an optimum number of subframes for each channel individually.
