Abstract From the Canadian patent

A base station synchronized Time Division Multiple Access (TDMA) System with a discontinuous control channel carrier is disclosed. Control channels are planned in a time reuse, overlaying the ordinary frequency reuse. Different base stations are allocated different timeslots for control channel transmissions. The control channels are allocated timeslots in a slot hopping fashion, such that transmissions from different base stations are detected by only monitoring one timeslot. Thus, MAHO measurements are possible on all neighbors, and no traffic allocation will continuously coincide with control channel transmissions from certain base stations.

Why it's free to use

  • Filed May 23, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 23, 2020.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 23, 2022.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
