20090122776 | SYSTEM AND METHOD OF VERIFICATION OF HSDPA LAYER 1 CODING IN A NODE - A system and method of verifying layer 1 coding in a node. The method begins by conducting downlink processing of user data by a node. The node then outputs coded data. Next, downlink processing of the user data is conducted by an independent reference model. The independent reference model utilizes scheduler decisions from the node to conduct the downlink processing. The reference model then outputs coded data. The coded data from the node is compared with the coded data from the reference model. If the coded data from the node is substantially similar to the coded data from the reference mode, the coded data from the node is correct. | 05-14-2009 |

This inaccuracy is calculated in a positioning node of the cellular communications system, preferably by filtering of measurements received from user equipments. Linear trend Kalman filtering followed by post processing of estimation errors may be utilized. In order to ensure non-ambiguous interpretation of the received time stamps of received satellite signals provided by user equipments, a pseudo propagation delay is computed in both the user equipment and the positioning node based on GPS acquisition assistance data. The GPS time stamp is then defined referring to the determined pseudo propagation delay. In one embodiment, the pseudo propagation delay is assured to be situated within a pre-determined time interval. | 01-17-2013 |
