    Abstract: A system and method in which a base station treats the Channel State Information (CSI) from wireless terminals as only partially-stale, and exploits this partially-stale CSI to predict the current channel from old estimates of the channel. The predicted channel is then used to design a precoder. The base station shapes the transmitted signal with the precoder so as to match it as closely as possible to the current channel. Particular embodiments thus combine the benefits of the stale feedback scheme with precoding to match the channel. Consequently, the signal received at a terminal is better conditioned, thereby providing a greater overall boost in performance of the communication arrangement between the base station and the terminal. The usage of partially-stale CSI can be important for dense networks with a large number of simple terminals.

    Abstract: In a wireless transmission device provided with an adaptive modulation circuit and a control method for the adaptive modulation circuit, an Ethernet signal received from a wired transmission path is transmitted to an opposite station one-to-one via a wireless transmission path and the Ethernet signal in the opposite station is again output to the wired transmission path. A traffic-statistics circuit which accumulates a traffic volume of a time zone-specific Ethernet signal as statistical data is provided. A wireless transmission capacity can be reduced by decreasing a multi-level number of a modulation scheme in a time zone in which the traffic volume is small based on the accumulated statistical data.

    Abstract: Systems (100) and methods (700) for increasing a predictability of Telematic Operations (“TOs”) of a Teleoperation System (“TS”). The methods involve: measuring an inherent latency of a Communications Link (“CL”) of TS which varies unpredictably over at least a first window of time; analyzing the inherent latency, which was previously measured, to determine a first reference value useful for increasing the predictability of the TOs; using the first reference value to select an amount of controlled latency to be added to CL (120) at each of a plurality of time points (502-518); and adding the amount of controlled latency to CL at each of the plurality of time points so as to increase the predictability of the TOs. In some scenarios, the amount of controlled latency added at a first time point is different than the amount of controlled latency added at a second time point.
