摘要： A wireless device (24) includes a modem (56) and processing circuitry (50, 52). The modem is configured to modulate signals for transmission over wireless channels, and demodulate signals received over the wireless channels. The processing circuitry is configured to receive a first frame from a second wireless device over a wireless channel via the modem, and transmit a second frame to the second wireless device via the modem over the wireless channel, to calculate a first Channel State Information (CSI) based on the first frame, to calculate a first normalized CSI by applying to the first CSI a normalization procedure, and generate, based on the first normalized CSI, a first key that due to the normalization procedure has an increased likelihood to match a second key generated in the second wireless device based on the second frame, and to communicate securely with the second wireless device over the wireless channel using the first key.

摘要： A method for communication includes communicating between a first transceiver and a wireless communication terminal on a first channel, while identifying the first transceiver to the terminal with a transceiver identity. A roaming condition, which determines whether the terminal is to roam to a second transceiver operating on a second channel, is evaluated. Upon meeting the roaming condition, the terminal is instructed to switch to the second channel, and the terminal is subsequently communicated with using the second transceiver on the second channel while identifying the second transceiver to the terminal with the same transceiver identity as the first transceiver.

摘要： System and method for backoff correction of channel quality information (CQI). A correction factor is calculated based on a goodness measure such as packet error rate (PER). The selection of modulation and coding scheme (MCS) is made considering the channel quality information (CQI) adjusted by the correction factor. A meaningful goodness measure can be imposed if the goodness measure is very low. A different correction factor can be calculated for different confidence levels, MCSs and transmission modes.
