摘要： The propagation time for propagation of a radio signal (93) from a radio transmitting station to a radio receiving station (91) is estimated based on calculated correlation values (102), calculated energy values (101) and a known energy value. The receiving station (91) receives a series of received signals (93) that respectively correspond to radio signaling bursts transmitted by the radio transmitting station. Each of the radio signaling bursts includes a known signaling sequence. The calculated correlation values (102) are indicative of correlations between the received signals and the known sequence, the calculated energy values (101) are calculated for the respective received signals, and the known energy value is the energy of the known sequence.

摘要： A method for uplink channel estimation comprises providing (210) of a channel state model in a channel estimator. An uplink radio signal of a present time slot is obtained (220) in the channel estimator as well as a series of transmit power control commands (230) issued for controlling a transmit power of the uplink radio signal. A delay between the time a transmit power control command is issued and the time that the transmit power control command is applied is estimated (232) based on measurements of the particular received uplink radio signal. Channel states are adapted (234) based on a transmit power control command compatible with the estimated delay. After the adaptation, channel states of the present time slot are estimated (240) in the channel estimator, by tracking the demodulated uplink radio signal with the channel state model. A channel estimator performing such method is also described.

摘要： Allocation of cell IDs in a cellular communication system includes determining a candidate allocation pattern of primary and secondary synchronization signal sequences for a candidate set of two or more cells. A performance metric is applied to the candidate allocation pattern to ascertain a performance indicator for the candidate allocation pattern, wherein the performance indicator indicates a quality of positioning performance for the candidate set of two or more cells. Cell-specific positioning performance for each cell in the candidate set of cells can be considered to derive the performance indicator of the candidate allocation pattern. If the performance indicator indicates acceptable positioning performance, primary and secondary synchronization signal sequences are allocated to respective ones of base stations corresponding to the two or more cells in accordance with the candidate allocation pattern. Otherwise, the process is repeated for a different candidate allocation pattern.

摘要： In a mobile telecommunications network, a mobile station (MS) (12) is configured to generate and uplink transmit position measuring data (54, 70) prior to and/or during a call connection, without noticeably interrupting the user or degrading the quality of service provided. Position measuring data (54, 70) can be uplink transmitted over an idle traffic channel during a call set up operation for a brief moment while the call connection is being completed. Position measuring data (54, 70) can also be uplink transmitted during a call by selectively stealing data positions or burst positions in the uplink signal. The position measuring data (54, 70) is received by a plurality of base stations (14) and uplink signal characteristics are measured and collected. The measured uplink signal characteristic data from several base stations (14) is then used to determine a current approximate geographical location of the mobile station (12).

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： A method in a signalling device (150) for assisting in positioning of a user equipment (120) based on time measurements is provided. The signalling device is associated to an s-cell (160), the s-cell (160) being recognized by the first network node (110) as an s-cell with limited functionality and is therefore not considerable for the user equipment (120) as a candidate cell for serving the user equipment (120) for data transmission The signalling device associated s-cell is comprised in a positioning neighbour list of neighbour cells. The neighbour cells in the list are adapted to be performed time measurement on by the user equipment for enabling positioning. The signalling device is configured to transmit predefined reference signals in predefined subframes and according to a predefined pattern relating to preselected subcarriers and preselected time slots within a subframe. The signalling device obtains synchronisation information. The signalling device transmits reference signals according to the configuration and being synchronized according to the obtained synchronisation information. This enables the user equipment to receive and perform time measurements on the transmitted reference signals for positioning when the signalling device associated s-cell is comprised in the positioning neighbour list.
