摘要： In a wireless network comprising access points deployed within a designated zone of coverage, the radio frequency field strength resulting from radiation from the access points is optimised as a function of location by means of control of the transmission power and/or radiation pattern of the access points in response to measurements from sensors at defined locations that measure received signal power, the received power being related to radio frequency field strength. Sensors may be deployed within the designated zone of coverage, at the edge of the zone and/or outside the zone and optimization of the transmission parameters of the access points in terms of transmission power and/or radiation pattern is carried out taking into account the location of the sensors in addition to the received power at the sensors.

摘要： The present invention presents a method, arrangement and computer program product for clocking exploiting the relative behavior of clocks of individual receiving stations as well as a corresponding modeling to derive a time difference of arrival of a signal from a user device which can be used to correct the time difference of arrival based on the modeled clock behavior and leads to a correct clocking of received user signals without the need of synchronization of the clocks in the various receiving stations. This principle is applicable to a plurality of pairs of receiving stations and beacon signals transmitted amongst them and allows for a correct location estimation of a user device.

摘要： In a cellular wireless system, power thresholds used for determining whether to add or drop servers held in a set of servers, such as an active set, for serving a user equipment (UE) are determined based on the motion of the respective UE. A lower threshold may be used with respect to the adding or dropping of a given server to or from a set of servers for serving a fast moving UE than would be used for the same server with respect to adding or dropping to or from a set of servers for serving a slow moving UE, while maintaining a given quality of service. As a result, the average number of servers held in sets is reduced in a typical network that comprises a plurality of UEs moving at different speeds, compared to a situation in which the threshold is set irrespective of the motion of a UE.

摘要： The present invention relates to estimating the Angle of Arrival (AoA) of a signal from a user equipment received at a base station of a wireless telecommunications network where the base station has a multi-beam antenna. A signal received from a user equipment is received by the each of the multiple beams of the antenna, and the two adjacent beams receiving the highest amplitude from the end user are selected. A ratio of functions of the amplitudes of the two selected beams, such as a ratio of the difference between the amplitudes of the two beams to the sum of the amplitudes is calculated and compared to a data store of ratios. The data store stores expected ratios corresponding to AoAs and the calculated ratio is compared to the pre-calculated expected ratios to extract an estimate of the AoA of the signal from the user equipment.

摘要： A method of estimating user location involving collecting data from the access points in the network. The data can then be used to define a relationship, for example the loss of power experienced by a transmitted signal, between the access points. The relationship can be stored within a matrix, database or any other suitable storage method that can be referenced to determine the position of a user device within the network and correlated with corresponding measurements from a user device to determine the location of the user device within the network.

摘要： A vehicle and method for controlling an engine in a vehicle are provided. A temperature of a lubricating fluid in the engine is determined, as are first and second engine speed limits. Operation of the engine at the first engine speed limit is limited to a predetermined time period when the lubricating fluid temperature is between first and second predetermined temperatures. The engine speed is at least temporarily limited to the second engine speed limit after the engine has been operated at the first engine speed limit for the predetermined time period and the lubricating fluid temperature is between the first and second predetermined temperatures.

摘要： A system and method for controlling an engine in a vehicle to facilitate heat transfer to a passenger compartment is provided. A number of conditions are examined, and if it is found that one or more of these conditions matches a corresponding predetermined condition, the spark timing of the engine is retarded. In addition, a charge motion control valve is opened, thereby increasing the amount, and reducing the turbulence, of the air entering the engine. This facilitates hotter combustion within the engine, and therefore faster heat transfer to the vehicle passenger compartment.
