Patent number: 10009281Abstract: A Radio Base Station (RBS) and a method performed by the RBS comprises receiving a frame F1 from a network node, the frame having a sequence number N. If the last received frame F0, prior to the received frame F1, has a sequence number lower than N?1, then starting a first timer T1 having a predefined length in time and temporarily storing the received frame F1. If a subsequent frame F2 having a sequence number lower than N and higher than the sequence number of frame F0 is received, then the received frame F2 is stored. When all frames having a sequence number between the sequence number of frame F0 and N have been received during the predefined length of the first timer T1, then forwarding the stored frames and/or received frames to the UE in the order of the sequence numbers.Type: GrantFiled: February 14, 2014Date of Patent: June 26, 2018Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Anders Jonsson, Aleksandar Jovanovic, Roger Wallerius

Publication number: 20130016005Abstract: 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.Type: ApplicationFiled: September 13, 2012Publication date: January 17, 2013Inventors: Jan LINDSKOG, Anders ANDERSSON, Roger WALLERIUS

Patent number: 8214711Abstract: A method and apparatus for a base station engaging in transmissions via at least a media access layer with a user entity are disclosed. The base station transmits data to the user entity over a high speed scheduling and packet data scheduling channels. 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 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.Type: GrantFiled: December 28, 2006Date of Patent: July 3, 2012Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Jan Lindskog, Roger Wallerius, Rikard Thomasson
