摘要： 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 sendingthe measured value to the user equipment and/or to a positioning node comprised within the wireless communication system.

摘要： Method and arrangement in a positioning node and a user equipment,for providing, and retrieving, respectively, geographic region data. The geographic region data comprises geographic position data. The positioning nodeiscomprised in a wireless communication system. The positioning node receives geographic position data associated with the location point of a first user equipment. The positioning node also receivesa first radio fingerprint. The radio fingerprint is based on a first signal propagation time measurement, measured with respect to the location point of the first user equipment. The received first radio fingerprint is then associated with the received geographic position data and clustered together to create cluster boundaries, defining geographical region data. When a second radio fingerprint is received, this is compared with previously received radio fingerprints. If a correspondence is detected, the geographic region data of the previously received radio fingerprint is sent to the second user equipment.

摘要： A technique for generating a reference signal for use in a communication system in which for reference signal generation multiple base sequences are defined is presented. A method implementation of the technique comprises generating a first reference signal sequence from a first base sequence and a second reference signal sequence from a second base sequence. In a next step, a reference signal is generated that comprises the first reference signal sequence and the second reference signal sequence.

摘要： In a wireless network supporting aggregation of uplink component carriers, sounding reference signals, SRS, are transmitted (62) on an uplink, UL, primary component carrier. An activation command corresponding to an UL secondary component carrier, SCC, is received (64), in response to which the receiving transceiver determines (65) whether it has valid timing information for the UL SCC, wherein valid timing information for the UL SCC indicates that the UL SCC is UL synchronized. In response to this determination, transmission of SRS on the UL SCC is enabled (66) if the UL SCC is synchronized, when SRS is configured for the UL SCC. Otherwise, transmission of SRS on the UL SCC is prohibited (68) until the UL SCC is UL synchronized.
