Abstract: A method and corresponding apparatus for providing a cellular subscriber with access to a WLAN are provided. They involve identifying a multimode mobile terminal, which corresponds to the subscriber and the WLAN from an access request. Based on the identification, the WLAN is authorized to provide the mobile terminal with access. The mobile terminal is then provided with access to the WLAN as a cellular subscriber and enables interoperability between the two networks. For example, the subscriber does not have to supply a credit card to pay for WLAN access directly. Instead, the subscriber pays a cellular network provider, and, in turn, the cellular network provider pays a WLAN provider for the access.

Abstract: A method includes receiving an Orthogonal Frequency Division Multiplexing (OFDM) signal comprising a plurality of Doppler-shifted OFDM subcarriers and determining frequency-shift data corresponding to the plurality of Doppler-shifted OFDM subcarriers. The determining includes calculating frequency-shift data for each Doppler-shifted OFDM subcarrier of the plurality of Doppler-shifted OFDM subcarriers, thereby yielding a plurality of subcarrier-specific frequency-shift values and calculating an average of the plurality of subcarrier-specific frequency-shift values. The method further includes frequency shifting each subcarrier of the plurality of Doppler-shifted OFDM subcarriers by a value based on the determined frequency-shift data multiplied by a frequency index of each subcarrier.

Abstract: In one embodiment, a method is performed by a wireless station. The method includes receiving from an access point (AP) a request for measurement of at least one link-quality parameter. The method further includes measuring the at least one link-quality parameter to generate a link-quality-parameter measurement. The method also includes determining, for the wireless station, an appropriate wireless-station category of a plurality of wireless-station categories. The plurality of wireless-station categories are defined based at least in part on the link-quality-parameter measurement. In addition, the method includes communicating with the AP in accordance with a transmission schedule corresponding to the plurality of wireless-station categories.
