Abstract: In one embodiment, a method is performed by a wireless station. The method includes determining that a wireless network provides relay service. The wireless network includes an access point and one or more relay nodes. The method further includes transmitting a relay-service desirability indication to the access point. The method also includes receiving a relay-service confirmation from the access point. The wireless station is operable to transmit at a first station-transmission power level during a first time period and a second station-transmission power level during a second time period. The second station-transmission power level is a reduced station-transmission power level as compared to the first station-transmission power level. In addition, the method includes transmitting an uplink transmission at the second station-transmission power level responsive to the relay-service confirmation from the access point.

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: Power saving in wireless networks is disclosed. A wireless network entity that includes a module to enable a reduction in power consumption in that wireless network entity is also disclosed. The module is configured to determine that a selected wireless station of one or more wireless stations associated with the wireless network entity in a same wireless network will transmit system control information (including synchronization information and service identification information) that is normally transmitted by the wireless network entity.
