摘要： A method and apparatus for world-mode devices capable of managing technology selection for multimode roaming between existing access technologies, as well as possible future access technologies, in a manner that eliminates wasteful scanning for non-existent systems and reduces roaming charges is disclosed. The method allows the device an opportunity to reacquire its home system before scanning for available roaming network resources in a prioritized manner that mitigates roaming costs, while conserving power and acquisition delays by eliminating scanning for non-existent system types. A minimum OOS duration is imposed on a home system before acquisition of a roaming partner to provide more time to re-acquire the home system. Preferred partner scanning and acquisition reduces roaming charges, while scanning for non existent systems is eliminated altogether.

摘要： A method of switching between Coherent and Non-Coherent demodulation based on computed metrics, in cases where stereo FM broadcasting stations do not adhere to RDS broadcast specifications. Re-utilizes existing hardware to demodulate RDS data in mono. The residual frequency offset is resolved using a Non Coherent demodulator and a time tracking algorithm. RDS data relies on the 57 kHz sub-carrier that is generated using 19 kHz pilot tone. In Mono broadcasting pilot tone is not present. A local 57 kHz free running signal is generated, and this is then used to demodulate the RDS data in Non-Coherent mode.

摘要： A method and apparatus for performing spectral allocation for a wireless link in a wireless communication system is disclosed. The method determines a distance/range for the wireless link and assigns an optimal sub-carrier frequency to the wireless link based on (1) a higher frequency to lower frequency priority and (2) on the value of the distance/range of the wireless link. Higher frequency sub-carriers are assigned to wireless links that have a shorter distance/range and lower frequency sub-carriers are assigned to wireless links that have a longer distance/range.

摘要： Interference from other wireless technology co-resident on a Bluetooth-capable device may render one or more Bluetooth frequencies unusable for a Bluetooth introduction sequence. In this case, one or more usable frequencies may be substituted for the one or more unusable frequencies to permit the introduction sequence to proceed. The one or more usable frequencies may be selected from a known set of usable frequencies in the current Bluetooth frequency train. Alternatively, a frequency re-mapping process may be used to select the one or more usable frequencies from the current Bluetooth frequency train.

摘要： Disclosed are methods and apparatus for interference cancellation in a wireless communication system. In particular, the disclosed methods and apparatus provide for interference cancellation in a wireless device, including extending linear interference cancellation techniques, such as quasi-linear interference cancellation (QLIC), in the wireless device to a first orthogonal set, which may be a first quasi orthogonal function (QOF) set for a cdma2000 system to cancel interference from that set upon another desired QOF set. QLIC may also be extended to cancelation of signals from non- intended base stations as well. Accordingly, the present methods and apparatus afford reduced interference through QLIC by canceling signals due to either undesired QOF sets or non-intended base stations, which in turn results in an increase in forward link capacity.

摘要： Mechanisms for optimizing the selection of a new legal channel during regulatory domain changes and improving the user experience during changes in the underlying physical link having wide applicability to many wireless communications links are disclosed. Applications comprise cellular networks, WLANs, WPANs. Wireless USB, high speed channels for Bluetooth and other uses of WiMedia as well as a wide range of radio technologies that use a number of time and/or frequency-domain separation techniques to create multiple channels in a given portion of the RF spectrum where there is no global agreement on the use of the RF spectrum. Differences could pertain to permitted frequency ranges, permitted power levels, requirements to detect and/or avoid other radio technologies, indoor/outdoor use requirements, and many others. The disclosed embodiments provide a method for taking advantage of, or at least minimizing the impact of, a change in the channel link which impacts the channel characteristics such as the available bandwidth.
