Method and arrangement in a first node for providing geographical position related information. The first node and a second node are comprised within a wireless communication system. The first node and the second node are adapted to exchange wireless signals. The method comprises receiving a signal from the second node. Apart of the received signal that has propagated through a first channel path from the second node is detected by using a circular correlator. A timing estimate associated with the propagation time of the part of the signal which is received over the first channel path from the second node is calculated. Thus the calculated timing estimate is provided, which timing estimate is to be used when determining the geographical position.

A method for providing geographic region data includes receiving geographic position data associated with a location point of a first user equipment and receiving a first radio fingerprint. The method also includes associating the received first radio fingerprint with the received geographic position data and clustering the received geographic position data to create cluster boundaries defining geographical region data. The method further includes receiving a second radio fingerprint and comparing the second radio fingerprint received from the second user equipment with previously received radio fingerprints being associated with geographic region data, and if the second radio fingerprint corresponds to a previously received radio fingerprint, associating the geographic region data of the previously received radio fingerprint with the location point of the second user equipment, and providing the geographic region data, associated with the location point of the second user equipment.

Method and arrangement in a base station, a user equipment and a positioning node, for sending, and obtaining, respectively, a value of a propagation delay of a signal. The signal is sent to the base station from a user equipment. The base station and the user equipment are comprised within a wireless communication system. Also, the base station and the user equipment are adapted to exchange wireless signals. The method is characterised by the step of receiving a signal sent from the user equipment. The method is further characterised by the step of measuring the value of the signal propagation delay of the received signal. Still further, the method is characterised by the step of sending the measured value to the equipment and/or to a positioning node comprised within the wireless communication system.
摘要:
A method in a first node for determining a round trip time of a signal sent between the first node and a second node includes sending a first signal to the second node and receiving a second signal, corresponding to the sent first signal. The second signal is sent from the second node as a response to the sent first signal. The method also includes computing the round trip time of the signal and sending the computed round trip time to the second node.

摘要:
The present invention relates to methods, a user equipment and a radio base station in a communication network, in which a downlink out-of-coverage is detected based on measurements done on a common channel or on the combination of common and dedicated channels. The out-of-coverage is then reported to the network, either using resources proactively assigned to the user equipment, or by transmitting a predetermined pattern of signature sequences assigned to the user equipment.
摘要:
The present invention relates to a method, a base station and an interface for handover in a wireless communication network. Handover is initiated when the signal quality falls below a predetermined value. Random access serves as an uplink procedure to enable the UE to make handover from a first base station (eNodeB) to a suitable second base station (eNodeB). In the present invention, random access parameters are exchanged between second and first base station before said first base station signals said random access parameters to said user equipment.
