摘要： Reliable and efficient search windows are provided by allowing the adaptation of the code search window to be dependent on inaccuracy measures of relations between a cellular frame time and a satellite reference time. 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.

摘要： Method and apparatus for a base station engaging in transmissions via at least a media access layer with a user entity is disclosed. The base station transmits data to the user entity over a high speed scheduling channel and a high speed packet data scheduling channel. The base station has a plurality of hybrid automatic repeat request (HARQ) entities cooperating with a scheduler for transmitting frames from at least the base station to the user entity for a given HARQ process. Each HARQ entity receives either a not acknowledge signal or an acknowledge signal or detects a discontinuous transmission for a given HARQ process. The base station transmits a next data indicator to the user entity. The user entity has at least one buffer associated with a given HARQ process. The buffer stores and performs incremental combining of received data relating to data from the base station. The buffer is capable of being flushed.A method for a base station is disclosed. The method begins by awaiting a scheduling instruction and scheduling of download data. If the outcome from previous media access transmission or transmissions is detected as a discontinuous transmission the next data indicator is set to the value previously used. Otherwise the next data indicator value is toggled. Data for the given HARQ process is transmitted.
