Abstract
According to the present invention, different frequency reuse patterns are used when scheduling critical and non-critical data transmissions. More specifically, the present invention uses a first reuse pattern for scheduling the transmission of critical data and a second reuse pattern for scheduling the transmission of non-critical data. The invention can be applied to any inbound or outbound time slotted protocol that have message fragments spanning over one or more time slots. The reuse pattern can be varied slot by slot, to use a less aggressive reuse for communicating critical data and a more aggressive reuse for communicating non-critical data. As a result, data can be communicated more reliably and throughput can be increased by protecting critical data transmissions via a less aggressive reuse.
