Patent number: 12206754Abstract: A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.Type: GrantFiled: November 13, 2023Date of Patent: January 21, 2025Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Janne Peisa, Michael Meyer, Johan Torsner, Stefan Parkvall, Magnus Stattin, Mats Sagfors

Patent number: RE49808Abstract: A mobile station is configured to support handover from a source base station to a target base station. The mobile station receives signaling from the target base station that indicates Packet Data Convergence Protocol (PDCP) protocol data units which have been successfully received at the target base station. In response, the mobile station generates further PDCP protocol data units for missing PDCP service data units from corresponding PDCP service data units buffered at the mobile station. The generating comprises using a different header compression state from that which was used for the missing PDCP service data units and ciphering specific to a connection with the target base station. The mobile station transmits the further PDCP protocol data units to the target base station.Type: GrantFiled: January 21, 2021Date of Patent: January 16, 2024Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Magnus Stattin, Michael Meyer, Janne Peisa, Ghyslain Pelletier, Mats Fredrik Sågfors, Per Johan Torsner, Henning Wiemann
