Open the CIPO recordAbstract From the Canadian patent
A UE system implements dynamic link adaptation by adding or changing (Fig. 3E) control information to notify a receiver which timeslots and codes are currently active and which timeslots should be avoided. The UE provides synchronization such that the receiver knows which timeslots and codes the UE has used to map the coded composite transport channel onto physical channels. The UE attempts to avoid the timeslots which are experiencing transmission difficulties, while attempting to utilize the timeslots which are not experiencing transmission problems.

Why it's free to use
- Filed August 5, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 5, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 5, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
