摘要： Sensing wireless transmissions from a licensed user of a licensed spectral resource includes obtaining information indicating a number of adjacent sensors that are concurrently sensing wireless transmissions from the licensed user of the licensed spectral resource. Such information can be obtained from a main node controlling the sensor and its adjacent sensors, or by the sensor itself (e.g., by means of short-range communication equipment targeting any such adjacent sensors). A sensing rate is then determined as a function, at least in part, of the information indicating the number of adjacent sensors that are concurrently sensing wireless transmissions from the licensed user of the licensed spectral resource. Receiver equipment is then periodically operated at the determined sensing rate, wherein the receiver equipment is configured to detect wireless transmissions from the licensed user of the licensed spectral resource.

The method comprises selecting a collection of sequences of symbols and dividing the collection of sequences into a plurality of groups, wherein all sequences of a group comprise a same first set of symbols. The method also comprises selecting one of the groups, and letting the first set of symbols of the selected group indicate one or more standards corresponding to the one or more of the wireless communication receivers to be woken up. The wake-up signal is then constructed based on a sequence of symbols of the selected group. The sequences of symbols of the collection may be of different lengths and the selected group may comprise sequences of symbols of different lengths. In such embodiments, the step of dividing the collection of sequences into a plurality of groups may comprise letting a first sequence and a second sequence (wherein the first sequence has a shorter length than the second sequence) belong to a same group if the first sequence and any part of the second sequence (wherein the part has the same length as the first sequence) differ in less than a number of positions.

摘要： A wireless communication node (130) and method therein for generating beamformed signals by means of backscattering in a wireless communication network are disclosed. The wireless communication node (130) receives a radio frequency signal at a plurality A of antennas (310). Each antenna is coupled to one of a number of impedance matrices (330) by one of a plurality A of switches (320). The wireless communication node (130) generates a first baseband signal based on data symbols to be transmitted in a baseband signal generator (340). The states of each switch are controlled based on its specific switch control signal such that each antenna impedance is selected among a number M of impedances, and thereby the received RF signal at each antenna is modulated by the first baseband signal with its specific phase and reflected. The beamformed signals are generated by the plurality A of antennas by reflecting the modulated RF signals from each antenna.
