Open the CIPO recordAbstract From the Canadian patent
An adaptive time division duplexing (ATDD) method and apparatus for duplexing transmissions on a communication link in wireless communication systems. Communication link efficiency is enhanced by dynamically adapting to the uplink and downlink bandwidth requirements of the communication channels. Time slots are flexibly and dynamically allocated for uplink (Ta) or downlink (Tb Tc, Td) transmissions depending upon the bandwidth needs of a channel. Communication link bandwidth requirements are continuously monitored using sets of predetermined bandwidth requirement parameters. Communication channels configured to have either symmetric or asymmetric uplink/downlink bandwidths depending …

Why it's free to use
- Filed November 18, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 18, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 18, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
