摘要： A recursive method of calculating an inverse impairments matrix is used to generate an SINR estimate, which in turn is used to generate a CQI estimate. The recursive inverse impairments matrix calculation avoids the need to perform a computationally intensive matrix inversion, allowing for faster CQI estimate generation and consuming less power.

摘要： Methods and apparatus for determining a position estimate for a base station transceiver node in a wireless communication system are disclosed. Angle-of-arrival and/or timing advance measurements corresponding to transmissions received from mobile stations for which geographic locations are already known are combined with known locations for the mobile stations to estimate the position of the base station receiving the transmissions. This estimated base station position may be used, for example, in subsequent positioning of mobile stations for which locations are not already known, such as mobile stations not equipped with GPS technology. The estimated base station position may also be used to update a database of base station coordinates for the wireless network.

摘要： In a wireless communication network UE, an estimated signal to interference and noise ratio (SINR) is calculated for each potential transmission mode, and is reduced by a calculated SINR back-off value in response to errors detected in decoding data in each of a plurality of data streams. A Channel Quality Indicator CQI is then generated based on the reduced SINRs. Reducing the SINR estimates in the presence of known data errors allows a UE to more accurately track a target BLER.

摘要： A virtual network is created by providing antennas controlled by the same radio access station with control signals of virtual radio access stations. Sets of physical channels comprising the control signals are dedicated to the respective antennas, while sets of physical channels comprising only traffic channels constitute common resources for more than one antenna. One example embodiment is applied in antenna systems utilizing common antenna cables, whereby the radio access station is provided as a distributor having a central broadcast control signal injector and control signal selectors at the antennas.

摘要： A method, an apparatus and a computer program for determining a location at which satellite ranging signals (RS1-RS 4) have been received. At least one pseudorange selection cycle (511, 512), including an initial selection cycle (511), is performed and said location is determined utilizing the selected pseudoranges (1004). Said initial selection cycle includes: determining a first admissible pseudorange (r11) associated with a first satellite (SV1); determining (502) all pseudoranges (r21, r22, r31, r32) associated with at least two additional satellites (SV2, SV3) which combined with said first pseudorange (r11) form admissible relative pseudoranges; forming (503) a set (1001) of pseudorange vectors representing all possible combinations of said determined pseudoranges (r11, r21, r22, r31, r32) associated with said first (SV1) and at least two additional satellites (SV2, SV3); and forming (504) a set (1002) of selected pseudorange vectors by selecting at least one vector from said set (1001) of pseudorange vectors. At least when said set (1001) of pseudorange vectors includes plural vectors, said selecting includes evaluating each vector in said set (1001) of pseudorange vectors according to a predetermined rule.

摘要： In a cellular communications network, additional control signals comprising virtual base station identification data are distributed in the radio system from well defined locations by e.g. transmitters. Since there is a connection between each virtual base station identification data and the location from where it is transmitted, a mobile terminal can use the information for improving its position estimation according to conventional procedures. No modifications of the mobile terminals are therefore necessary. The mobile terminal is not able to connect to the communications system using the virtual base station identification data, since this data only is intended for position estimating purposes. In such a way, the devices for providing the additional information necessary for the improved position estimation can be made very simple and inexpensive.

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 at 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.
