Abstract
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.
Claims7
A method of passing information in a wireless network, comprising:
- dividing an available channel time in the wireless network into a plurality of sequential superframes;
- transmitting first signals from a first device only during one out of every K1 sequential superframes;
- and
- transmitting second signals from a second device only during one out of every K2 sequential superframes,
- wherein K1 and K2 are each chosen from the set consisting of powers of two.
A method of passing information in a wireless network, comprising:
- dividing an available channel time in the wireless network into a plurality of sequential superframes;
- and
- transmitting first through Nth signals from first through Nth devices, respectively, only during one out of every K1 to KN sequential superframes, respectively,
- wherein K1 to KN are each integers chosen from the set consisting of powers of two.
