摘要： Improved power control methods and power control systems are described wherein received RSSI values are processed to generate a power control signal which may be used by a link manager, or other element in a receiving station, to determine whether to send a power control message to the transmitting station. The method used to process the received RSSI values is dependent upon a value of the power measurement, for example, the method may involve a comparison between the value of the power measurement and a value of the power control signal. In another embodiment, the received RSSI values may be converted to power values and then smoothed using a filter.

摘要： A co-existence method is described. The method comprises setting a priority level of a slot based on the likelihood that the slot will be required by a first radio and signalling the priority level to radio which is co-located with the first radio and which shares a resource with the first radio. The slot may, for example, be a re-transmission slot following a primary transmission slot or may be a sniff anchor point. The likelihood may be determined based on one or more factors, such as historical data or knowledge of the activity of a peer of the first radio.

摘要： A wireless communication system comprising a plurality of radio devices and an interconnect to facilitate sharing of resources between the plurality of radio devices. Each radio device is coupled to the interconnect such that each radio device can communicate to all of the other radio devices to facilitate sharing of resources and each radio device can ascertain the identity of a radio device sending a signal to the interconnect. The radio devices may be coupled to the interconnect by any suitable means, for example resistively or capacitively and the signals sent to the interconnect may be at baseband or at radio frequencies. Orthogonal code techniques may be utilized to allow the identification of each radio device.

摘要： The present invention provides a locked loop circuit in which the input clock signal is delayed according to a saw-tooth signal in order to output a range of frequencies not necessarily equal to an integer multiple of the input clock signal. The absolute value of the delay (i.e. the difference between the maximum and minimum values of the saw-tooth delay) can be calibrated by detecting the value of the circuit phase detector at the wrap point of the saw-tooth.

摘要： An improved wafer level chip scale packaging technique is described which does not use an encapsulated via to connect between a redirection layer and a pad within the pad ring on the semiconductor die. In an embodiment, a first dielectric layer is formed such that it terminates on each die within the die's pad ring. Tracks are then formed in a conductive layer which contact one of the pads and run over the edge of an opening onto the surface of the first dielectric layer. These tracks may be used to form an electrical connection between the pad and a solder ball.
