摘要： A method and an apparatus in a first wireless station of a network transmitting to a second wireless station. The network uses multi-tone OFDM signals. The first station includes multiple antennas and a receive and a transmit signal path per antenna. Each receive signal path includes a discrete Fourier transformer determining the tones in a received signal, and each transmit signal path includes an inverse discrete Fourier transformer converting tones to a signal. The method includes determining channel estimates for each tone and each receive path while receiving from the second station, determining transmit weights to transmit to the second station, tone-by-tone weighting a signal for transmission to the second station to produce weighted tone sets for each transmit signal path, and transmitting the weighted tone sets. The first station is configured so that the weighting produces additive beamforming without the second station needing multiple antennas.

摘要： Provided is an all-terrain trailer for hauling large objects over uneven landscapes. The trailer is capable of carrying items within its volume in both its deployed and stowed state. Deployed, the trailer is a basket shaped body with a pair of wheels removably secured via a removable axle. The trailer is attached to the lead vehicle using a removable trailer hitch linkage that is secured to the basket body via fasteners. In a stowed state, the tires and axle are stored within a storage area in a lower portion of the basket body. In one embodiment, a false bottom is placed over the storage area, creating a flat trailer bed that objects can be laid upon. The basket body is removably secured to the hood of a lead vehicle, thereby providing a carrying basket while the vehicle is in transit.

摘要： In an example embodiment, there is disclosed a technique that enables a wireless device to achieve coexistence with an interfering source. The wireless device determines when interference is present and not present during a service period and reports the duration of interference free interval. At the end of an interference period, the wireless device can send a trigger signal indicating the start of an interference free interval to request data be sent to the wireless station until the expiration of the duration of the interference free interval. In particular embodiments, the signal sent by the wireless device can include an offset, for example a timing synchronization function (TSF) value, to indicate the end of the interference-free interval, perhaps computed so as allow for some clock drift.
