The invention relates to an operational state determination apparatus () for determining whether a variation in a determined electrical parameter of an electrical network () is caused by a variation in an operational state of an electrical consumer of the electrical network. The electrical network comprises multiple electrical consumers () and a voltage source (), wherein a variation classification unit () determines whether a variation in the determined electrical parameter of the electrical network is caused by a variation in the operational state of an electrical consumer of the network depending on a decision variable which depends on a variation in a measured voltage and a variation in a measured current of the electrical network. This determination can be performed, without directly using the variation in the determined electrical parameter of the electrical network and is therefore less influenced by random voltage fluctuations in the electrical network.

Operational state determination apparatus

The invention relates to adjusting at least one of installed building service sensors () of a building service system. A sensor coverage area of at least one sensor () is adjusted based on information on a position of the installed sensor () relative to at least one other sensor (). For example, to determine the position of the sensor () relative to said at least one other sensor (), each sensor () establishes a wireless communication between said sensor () and at least one other sensor () via a wireless communication means () of the sensor (). For example, information on the positions of the installed sensors () is used to assign to each sensor () at least one of installed building service supply devices () of the system.

The invention relates to controlling power consumption of a group of plurality of groups of power consuming devices by determining power consumption control value for controlling power consumption of devices of the group by use of at least one of the following: load shedding flexibility value of at least one group of plurality of groups, wherein the load shedding flexibility value of the corresponding group indicates maximum amount of power, by which power consumption of devices of the corresponding group can be reduced such that minimum power consumption permissible in the corresponding group is maintained; load restoration flexibility value of the at least one group of plurality of groups, wherein the load restoration flexibility value of the corresponding group indicates maximum amount of power, by which the power consumption of devices of the corresponding group can be increased such that maximum power consumption permissible in the corresponding group is maintained.

Commissioning of a building service system

The invention relates to a disaggregation apparatus () for being used in a multi-group electrical network (), which comprises multiple electrical groups (), each comprising one or more appliances (). A determination unit () determines an electrical group () comprising an appliance, of which an operational state has been changed, based on first changes in mains voltages (V, V, V) measured while the operational state change occurs, second and third changes in the mains voltages (V, V, V) measured while switchable loads () are switched, and the resistances (R, R, R) of the switchable loads (). Thus, a misdetection due to an operational state change of an appliance in another electrical group may be avoided and the accuracy of disaggregation may be improved in a multi-group electrical network ().

The invention relates to a disaggregation apparatus for identifying an appliance in an electrical network () comprising multiple appliances (). A voltage meter () measures a first change in a mains voltage (V) delivered to the appliances of the electrical network, while an operational state of an appliance is modified, and a second change in the mains voltage, while a switchable load is switched. An appliance determination unit () determines the appliance, of which the operational state has been changed, based on the measured first change in the mains voltage, the measured second change in the mains voltage and the resistance of the switchable load. Thus, an appliance can be determined without detecting switching flickers in very short time durations, i.e. high sampling rates and continuous monitoring are not necessarily required. This reduces the technical efforts of the disaggregation apparatus for performing the disaggregation function.

The present invention relates to a transmitting apparatus, a receiving apparatus, a system, a signal, and a method of multi-user transmission, wherein transmission settings are divided into common signal information, containing settings/information relevant for multiple receivers and user stream specific information, containing settings/information relevant only to a related user stream. Furthermore, the common signal information may comprise at least one of a duration of the longest user stream field and multi-user resource allocation field, so that the receivers know the mapping of user streams to receivers.

Signaling of transmission settings in multi-user systems

The present invention relates to a method, an apparatus and a computer program product for sensing and communicating in transmission systems with shared spectrum usage, which may comprise e.g. a cognitive relay system. The communication between a transmitter and a receiver occurs in two transmission phases via the assistance of a relay. Sensing is performed at the transmitter during the second transmission phase, thus overcoming the need for dedicated slots for sensing.

The present invention relates to a spectrum sensing scheme for a radio network. The proposed approach involves applying sensing in a distributed fashion to obtain an estimate of the signal spectrum. A network of the multiple sensing nodes (-to-J) obtains such a spectrum estimate without requiring high-speed analog-to-digital converter to accommodate the large band-width of interest.

Distributed spectrum sensing

The present invention relates to a method for communicating a signal to a first station from a second station, the stations having antenna array. For communication in bands like 60 GHz, it is advisable to carry out analog beam steering. But it is needed to compute all the beam forming weights in a single message. Then, the invention-proposes that for each signal, in the preamble, a plurality of training symbols are included, wherein during each training symbol repetition, the receiving station adjusts at least one antenna parameter of the plurality of antennas and measuring the combined signal for computing a set of antenna weights to be applied for an analog beam forming on the antenna array for receiving and/or transmitting the data field.

A method of synchronizing multi-carrier systems is provided, wherein the method comprises inserting a predefined frequency domain signal into a signal on a transmitter side of a multi-carrier system and multi-carrier modulating the signal. Furthermore, the method comprises transmitting the multi-carrier modulated signal via a carrier channel to a receiving side of the multi-carrier system, and synchronizing the multi-carrier modulated signal by using the predefined frequency domain signal portion of the multi-carrier modulated signal.
