    摘要: In one of its aspects the technology concerns a method of determining a position of a wireless terminal in a radio access network using information of the travel time of radio waves between a base station and the wireless terminal, the travel time information being retrieved in a way consistent with SUPL positioning. The method comprises performing, at the wireless terminal, a time of arrival measurement for a respective downlink radio frame received from a node associated with a cell of a radio access network. The method thereafter uses the time of arrival measurement and an estimated time of downlink transmission from the node to make a determination of a distance between the wireless terminal and the node. The distance so determined can be used to generate an ellipsoid arc for describing a round trip time positioning of the wireless terminal. As an optional enhancement, the method further includes generating a thickness dimension of the ellipsoid arc, the thickness dimension of the ellipsoid arc reflecting clock uncertainty.

    摘要: A method for noise rise estimation in a wireless communications system is presented, which comprises measuring of samples of at least received total wideband power. From the measured samples of at least received total wideband power, a probability distribution for a first power quantity is estimated. This first power quantity can be the received total wideband power itself. The probability distribution for the first power quantity is used for computing a conditional probability distribution of a noise floor measure. This computing is performed recursively. A value of a noise rise measure is finally calculated based on the conditional probability distribution for the noise floor measure. A node of a wireless communications system having the above functionality is also presented. Typically, the node is a RNC.

    摘要: A received total wideband power in a wireless communications system is measured (202) a number of times during a time interval. A site communication throughput is determined (204) and processed (206) into a time averaged site communication throughput. A probability distribution for received total wideband power is estimated (210) from the measured received total wide-band power. An estimate of a noise floor measure is computed (214) based on the probability distribution for received total wideband power and a noise rise measure is calculated (218) based on the probability distribution for received total wideband power and the estimate of a noise floor measure. According to the present invention, an adjustment (208) of the noise rise measure is provided based on the averaged site communication throughput.

    摘要: An inherent non-observability of the thermal noise power level is circumvented by estimating an upper limit of the thermal noise power level by time evaluations. An instantaneous total received wideband power is measured in a receiver. Preferably, also an instantaneous sum of powers of all links used in the same cell is provided. A quantity (P′), preferably the difference between the instantaneous total received wideband power and the instantaneous sum of powers of all links used in the same cell, is followed (110) during a time period (TLag). A minimum value (PMIN) of that quantity is then used as an estimate of the thermal noise power level upper limit. Preferably, the time period is configured as a sliding window. An improved determination of noise rise can then be calculated and used for controlling traffic within the cell.

    摘要: In a split antenna system, a radio network node determines an association between a target wireless terminal and an antenna being used to communicate with the target wireless terminal. The radio network node provides an association information and a signal information of properties of a wireless signal used for communication between the antenna to a positioning node. The association information can include the identity of the antenna, which can be encoded in least significant bits of a position measurement included in the signal information. The positioning node determines a position of the target wireless terminal based on the association information and the signal information.

    摘要: Teachings herein improve selection of the positioning method(s) used to obtain positioning information responsive to a positioning request, by approaching positioning QoS holistically. Approached holistically, a joint QoS metric as taught herein takes into account the joint effect of individual QoS parameters of a positioning method, or the joint effect of multiple methods in a sequence. Processing in one or more embodiments thus includes determining a joint QoS metric for each of a plurality of candidate positioning methods or sequences, and selecting a positioning method or sequence based on those joint QoS metrics. By selecting a positioning method or sequence in this way, holistically based on joint QoS metrics rather than a piecemeal approach based on a one-by-one check of individual QoS parameters, selection proceeds flexibly according to actual QoS requirements of position-based services and/or systematically according to the joint effect of multiple positioning methods.

    摘要: Method and arrangement in a Radio Base Station RBS in a wireless communication system, for handling load coupling in softer handover. The method in an RBS involves receiving (702) signals from a plurality of UEs connected to the RBS, using a category 1 receiver. Further, the load experienced by the respective UEs is determined (704). The effect of load coupling in softer handover of at least one of the UEs connected to the RBS is estimated (706), and, when the estimated effect of load coupling of a UE fulfills a predefined criterion (708:1), at least one entity in the RBS is modified (710), such that the effect of load coupling is reduced or avoided.

    摘要: A method of selecting the positioning method(s) used to respond to given positioning requests uses historical performance data reflecting the actual performance yielded by one or more of the positioning methods that are generally available for selection. As a non-limiting example, a positioning node maintains or otherwise has access to historical data reflecting the QoS obtained for at least some of the positioning methods supported by the node. Correspondingly, the node compares the QoS requirements associated with an incoming positioning request to the historical performance data, to identify the positioning method(s) that appear to best satisfy the requirements. The positioning node therefore selects the “best” method(s) for responding to a positioning request, not based on “generic” performance characteristics of those methods, but rather based on observed real-world performance of those methods, as applicable to the particular operating environment (radio environment) in which the positioning methods are carried out.

    摘要: A method and apparatus for reducing an effect of user interference on other users in an uplink of a radio access network using interference suppression. A user, for example, the user experiencing the highest interference, is selected from a plurality of users using the radio access cell. A perceived Rise over Thermal value for the user after interference suppression is predicted in the event that scheduling grants to an interfering user in the radio access network are altered. On the basis of the prediction, scheduling grants to the interfering user are altered, thereby reducing the interference for the selected user.
