    摘要: Methods and arrangements for wireless communications are contemplated. Embodiments include transformations, code, state machines or other logic to determine the signal to noise ratios (SNRs) of multiple stations associated with an access point in a wireless network. The embodiments may also include selecting whether one of the stations communicates with the access point by an orthogonal frequency division multiplexing (OFDM) transmission method or a multiple-access joint coding/decoding transmission method, the selecting based upon the SNRs and communicating the selected transmission method to the station of the multiple stations. Some embodiments may include determining an SNR threshold level, selecting the MAC transmission method if the SNR of at least one of the multiple stations is below the SNR threshold level, and selecting the OFDM transmission method if the SNRs of all of the multiple stations are above the SNR threshold level. Other embodiments are described and claimed.

    摘要: Methods, protocols and systems for communicating in a multi-hop wireless mesh network may include explicitly providing information relating to backhaul wireless link qualities in multi-hop wireless mesh network to next generation subscriber stations in a first mode. In a second mode, embodiments are configured to implicitly provide indicia of multi-hop wireless link qualities to legacy subscriber stations by adjusting a transmit power of frames sent to the legacy subscriber stations. Other embodiments and variations are described in the detailed description.

    摘要: Partial channel information is used to weight signals being transmitted by cooperating nodes within a cooperative diversity arrangement. In at least one embodiment, the phase of the complex conjugate of a channel coefficient between a cooperating node and a remote device is used to weight a transmit signal.
