20130158911 | QUANTISED MONITORING OF POWER-CONSUMPTION - A power-consumption monitoring device, for taking measurements of the power consumed by an appliance. The device is connectable to a mains electrical circuit and operable to transmit the measurements to a master device through the circuit. The device is adapted: to measure the energy consumed by the appliance in each of a series of time intervals, and maintain a first cumulative sum of the resulting energy measurements; to periodically transmit, to the master device, a first quantised value representing the cumulative sum; and to subtract the transmitted quantised value from the cumulative sum. | 06-20-2013 |
20130215933 | MONITORING OF POWER-CONSUMPTION - A power-consumption monitoring device, for taking measurements of the power consumed by an appliance. The device is connectable to a mains electrical circuit and operable to transmit the measurements to a master device through the circuit. Also presented is a master device, for receiving over a mains electrical circuit power-measurements transmitted by one or more power-consumption monitoring devices. Also presented is a power-line communications network comprising: a master device; and one or more power-consumption monitoring devices. | 08-22-2013 |
20130266043 | SIGNAL DETECTION IN NOISE - A method of detecting a transmission. The method comprises: measuring, from a first portion of a received spread-spectrum signal, a first code-phase of a spreading-code; measuring, from a second portion of the signal, a second code-phase of the spreading-code; comparing the first and second code-phases; and detecting whether the transmission is present according to the result of the comparison. Also disclosed are corresponding methods and apparatus for transmission and reception of signals. | 10-10-2013 |

20140126508 | METHOD AND APPARATUS FOR CONTROLLING CARRIER SELECTION IN WIRELESS COMMUNICATIONS SYSTEMS - A mobile communications system including: at least one base station configured to communicate data to/from different terminal devices via respective of plural logically separate carriers of a wireless access interface; first and second terminal devices operable to camp-on to first and second carriers of plural carriers and to subsequently communicate data with the at least one base station via the first and second carriers. The first and second carriers support compatible synchronisation signalling such that the first and second terminal devices both can synchronise with the first and second carriers to begin a camp-on procedure. Following synchronisation with one of the first or second carriers to begin the camp-on procedure, the second terminal device is configured to determine whether or not to continue with the camp-on procedure in dependence on an aspect of physical layer signalling associated with a control channel of the carrier with which it has synchronised. | 05-08-2014 |
20140153516 | CONTROLLING CARRIER SELECTION IN A WIRELESS COMMUNICATION SYSTEM - A mobile communications system including at least one base station configured to communicate data to/from different types of terminal devices via respective of plural logically separate carriers of a wireless access interface; first and second terminal devices operable to respectively camp-on to first and second carriers of the carriers and to subsequently communicate data with the at least one base station via the first and second carriers. The first and second carriers support compatible synchronization signalling such that the first and second terminal devices synchronize with the first and second carriers to begin a camp-on procedure, and following synchronization with one of the first or second carriers to begin a camp-on procedure. The second terminal device is configured to determine whether or not to continue with the camp-on procedure based on an aspect of physical layer signalling associated with a control channel of the carrier with which it has synchronized. | 06-05-2014 |
20140362831 | WIRELESS COMMUNICATIONS SYSTEM WITH A NARROWER SUBORDINATE CARRIER - Communicating by a terminal device using a host carrier with radio resource segments distributed in time is disclosed. Each radio resource segment may provide radio resources in a first frequency band. The terminal device may communicate with a base station using a second frequency band and a subordinate carrier that comprises radio resources of a subset of the radio resource segments of the host carrier. The second frequency band may be narrower than and contained within the first frequency band. | 12-11-2014 |
20140376509 | WIRELESS COMMUNICATIONS SYSTEM WITH A NARROWER SUBORDINATE CARRIER - Wirelessly communicating with a first type of terminal device and a second type of terminal device is disclosed. The first type of terminal device may have a host carrier having radio resource segments distributed in time. Each radio resource segment may provide radio resources across a first frequency band. A second type of terminal device may also communicate, within a second frequency band, using a subordinate carrier comprising resources that are a subset of the host carrier radio resource segments. The second frequency band may be narrower than and contained within the first frequency band. | 12-25-2014 |
