1. A method of scheduling communications over a frame having a plurality of time slots, comprising:
- assigning information to be transmitted between two terminals to a block of the time slots within a frame; and
reordering the time slot assignments within the frame using a permutation function, the permutation function being a function of frame count.

Abstract
Systems and techniques are disclosed relating to wireless communications. The systems and techniques involve wireless communications wherein a process, module or communications terminal schedules communications over a frame having a plurality of time slots. The process, module or communications terminal may be used to assign information to be transmitted between two terminals to a block of the time slots within a frame, and reordering the time slot assignments within the frame using a permutation function, the permutation function being a function of frame count.

12. A communications terminal, comprising:
-
a transceiver configured to receive a block of time slot assignments within a frame to communicate with a remote terminal; and
a controller configured to reorder the time slot assignments within the frame using a permutation function, the permutation function being a function of frame count. - View Dependent Claims (13, 14, 15, 16, 17)

18. A communications terminal configured to operate in a first piconet, comprising:
-
a transceiver configured to receive a block of time slot assignments within a frame for a transmission between a bridge terminal and a terminal in a second piconet, the bridge terminal belonging to the first and second piconets; and
a scheduler configured to reorder the time slot assignments within the frame using a permutation function for the second piconet, demap the reordered time slots within the frame using a permutation function for the first piconet, and use the demapped time slots as a constraint in assigning a block of time slots within the frame for a transmission between two terminals in the first piconet, the permutation for the first piconet being different from the permutation function for the second piconet. - View Dependent Claims (19, 20, 21, 22, 23)
