摘要： A mobile communication station in a wireless communication network is used to measure the respective times of arrival of radio signals respectively transmitted by a plurality of radio transmitters in the network. The mobile communication station is provided with real time difference information indicative of differences between a time base used by a radio transmitter serving the mobile communication station and respective time bases used by the other radio transmitters. The mobile communication station determines, in response to the real time difference information and relative to the time base used by the radio transmitter serving the mobile communication station, a plurality of points in time at which the respective radio signals are expected to arrive the mobile communication station. For each radio signal, the mobile communication station monitors for arrival of the radio signal during a period of time after the point in time at which the radio signal is expected to arrive.

摘要： Apparatus and method for reducing an air interface load in a communication network. A base station is provided with a receiver adapted to receive signals from a terminal via a Dedicated Physical Control Channel (DPCCH) and a second control channel. A measuring unit measures a signal to interference ratio (SIR) of the DPCCH. An effective SIR determining unit determines an effective SIR on the basis of the measured SIR of the DPCCH and an estimate of the SIR of the second control channel. A comparison unit compares the effective SIR with a target SIR, and a power determination unit determines a power control command for controlling power usage for the DPCCH on the basis of the comparison. A transmitter sends a message to the terminal, the message including the power control command. The invention allows the DPCCH power (or DPCCH SIR) operating point to be maintained at a low level.

摘要： The present invention relates to methods and apparatuses as well as a measurement report signal for reporting measurements on ranging signals (RS1-RS4) received by a mobile station from satellites (SV1-SV4) or calculating a position based on such measurements, wherein each of said ranging signal comprises a stream (201) of data bits (202) spread by a spreading code (203). After synchronizing (501) to data bit edges in the stream of data bits on a ranging signal, a position in time modulo the data bit length for said stream of data bits with respect to a selected point in time is measured (502). The measured position in time could be used by the apparatus performing the measurements on the received ranging signals for calculating (504) the position of the mobile station. Alternatively the apparatus could transmit (503) a wireless signal including data representing said measured position in time, allowing the mobile station position to be determined in another apparatus (101).

The arrangement comprises means for detecting the signal during the time ttot, wherein said means comprises a correlator adapted for combined coherent and non-coherent correlation, wherein the length of the coherent correlation interval is L signal samples, the number of coherent correlation intervals is M and the coherent correlation results in a coherent correlation result for each of the coherent detection intervals M, and means for adding the coherent correlation results non-coherently. Further, the arrangement comprises means for selecting one of the length L of coherent detection interval and the total detection interval ttot based on at least one of the parameters cell size, UE speed and acceleration, number of participating Location Measurements Units and a desired total false alarm rate.

摘要： A wireless communication network determines positioning data for a given mobile terminal, in response to receiving a positioning event trigger for that mobile terminal. The network sends the positioning data to the mobile terminal via control-plane signaling, for transfer by the mobile terminal to the user plane. Correspondingly, the mobile terminal receives the positioning data over the control plane, transfers it to the user plane, and transmits the positioning data or location information derived from the positioning data, via user-plane signaling. As such, network-performed positioning measurements and/or geographic coordinate data derived therefrom are transferred from the control plane, to the user plane, for flexible and transparent transmission from the mobile terminal to a given node having a user-plane connection with the mobile terminal. Such a node may be essentially any type of communication device, system, or server, internal or external to the network.

摘要： A method and apparatus for determining the content in bursts to be transmitted from a base station in a mobile network on a broadcast frequency in specific timeslots of a broadcast frequency frame structure. A current state of the logical channel allocated to the forthcoming burst is checked, and the content in the forthcoming burst is determined depending on the current channel state. A dummy burst with a base station specific training sequence is transmitted if there is no data to transmit, and if the dummy burst cannot be confused with a regular traffic burst according to the current channel state. The dummy burst contains no intelligible information to mobile terminals.

摘要： A virtual network is created by providing antennas controlled by the same base station with control signals of different virtual base stations. A virtual network controller comprised in the base station is arranged for performing handovers between sets of physical channels of the different virtual base stations. The handover is preferably performed transparently towards the main communication network. This transparency is preferably provided by associating physical channels of virtual base stations with communication channels of the main communications network. Preferably, position estimations of a mobile terminal connected to the base station are performed by the virtual network controller, whereby such estimations can be kept secret within the virtual network.
