Publication number: 20070054620Abstract: A correct escape mechanism is determined according to interference type. Transmission is arranged so that interference may be measured at all time slots as needed to compute a measure of variance in interference in time slots. If the variance is above a predetermined value, time division duplex escape mechanisms are employed. If the variance is below a predetermined value, appropriate escape mechanisms are employed depending on whether the escape mechanism is being implemented during an uplink or downlink. Interference causing FDD WTUs may be handed over to carrier bands to control interference experienced by TDD users.Type: ApplicationFiled: November 6, 2006Publication date: March 8, 2007Applicant: InterDigital Technology CorporationInventors: Eldad Zeira, Teresa Hunkeler

Publication number: 20060277450Abstract: A method for determining whether a data transmission rate in a wireless communication system is appropriate for current system conditions begins by calculating a frame error rate (FER) for a given period of time and obtaining a current data rate. If the current data rate is greater than a minimum data rate and the FER is a high value, then the system switches to a lower data rate. If the current data rate is greater than a minimum data rate and the FER is less than a high value, then the system maintains the current data rate. If the current data rate is less than a maximum data rate and the FER is a low value, then the system determines whether a higher data rate can be used.Type: ApplicationFiled: July 28, 2006Publication date: December 7, 2006Applicant: InterDigital Technology CorporationInventors: Maged Zaki, Shamim Rahman, Teresa Hunkeler, Guang Lu

Publication number: 20060121929Abstract: A startup process of an access point (AP) includes a discovery phase and an announcement phase. During the discovery phase, the AP detects neighboring APs from its own extended service set (ESS), neighboring APs from different ESSs, and external sources of interference. During the announcement phase, the AP transmits its beacon signals at maximum power in order to accelerate recognition by neighboring APs running the discovery phase. An automatic initialization channel selection process of an AP scans channels the AP will use to communicate. Information of each scanned channel is recorded and a best performance channel is determined for use by the AP.Type: ApplicationFiled: January 17, 2006Publication date: June 8, 2006Applicant: InterDigital Technology CorporationInventors: Christopher Cave, Angelo Cuffaro, Paul Marinier, Teresa Hunkeler, Juan Zuniga, Vincent Roy
