A method is provided to pass information in a wireless network. The available channel time in the network is first divided into a plurality of sequential superframes. Some devices may need to transmit during every superframe, but others will only need to transmit during a fraction of the superframes. These devices are assigned sub-rate time slots in the superframes at sub-rates that must be a power of two. In other words, they can only be assigned sub-rate time slots every second superframe, every fourth superframe, every eighth superframe, etc. This allows the sub-rate time slots to be spread more evenly throughout the plurality of sequential superframes, and minimizes the amount of overlap possible.
