Patent number: 12107690Abstract: A user equipment unit (30) and a base station node (28) which is configured for operation with a synchronous HARQ protocol and with capability of sending data on an E-DCH channel either (1) in a nominal mode in single transmission time intervals of a predetermined length, or (2) in an extended mode in a pseudo transmission time interval. The pseudo transmission time interval comprises a first transmission time interval in which the data is transmitted and a second transmission time interval in which the data is re-transmitted. The second transmission time interval is consecutive to the first transmission time interval, and the first transmission time interval and the second transmission time interval are each of the (same) predetermined length.Type: GrantFiled: December 19, 2017Date of Patent: October 1, 2024Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Per Johan Torsner, Eva Englund, Stefan Parkvall, Mats Fredrik Sågfors

Publication number: 20240098739Abstract: The present invention relates to a method and apparatus for requesting scheduling of resources to be used for uplink communication of data in a communications system. If the repeated transmission by a user equipment of scheduling requests on an uplink control channel is determined to be unsuccessful, a random access transmission on a random access channel is initiated as a fallback procedure.Type: ApplicationFiled: November 28, 2023Publication date: March 21, 2024Inventors: Jessica Östergaard, Anders Furuskär, Mats Sågfors, Carola Faronius, Peter Moberg, Magnus Stattin, Ghyslain Pelletier, Johan Torsner, Walter Müller

Publication number: 20240080175Abstract: 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: ApplicationFiled: November 13, 2023Publication date: March 7, 2024Inventors: Janne Peisa, Michael Meyer, Johan Torsner, Stefan Parkvall, Magnus Stattin, Mats Sagfors

Publication number: 20230224085Abstract: The invention discloses a method (700) for a cellular system (100), in which traffic can be exchanged between first (110, 120) and second (110, 120) transceivers. The traffic is sent in data units, each of which is given an identifier, and which data units may be divided into segments. A receiving transceiver (110, 120) may send status information in data frames or data units (200, 300) about properly received, partially received, or non-received data units to a sending transceiver, i.e. the transceiver from which the data was sent. In the case (705) of partially or non-received data units, the status information includes (710) information about whether the data unit or units were non-received or partially received, and in the case of one or more partially received data units, which (715) parts of those data units that were not received.Type: ApplicationFiled: March 20, 2023Publication date: July 13, 2023Inventors: Johan Torsner, Michael Meyer, Henning Wiemann

Patent number: 11611410Abstract: A method for use in a cellular communications system in which system traffic can be exchanged between transceivers comprises receiving traffic from a second transceiver at a first transceiver. The traffic includes data units that are each associated with an identifier. The data units are also divided into segments. The method additionally includes sending status information from the first transceiver to the second transceiver. The status information pertains to one or more data units transmitted by the second transceiver. Additionally, sending the status information includes, for non-received and partially received data units, sending information indicating the data units were non-received or partially received and, for partially received data units, sending information indicating which parts of the data units were not received.Type: GrantFiled: November 19, 2020Date of Patent: March 21, 2023Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Johan Torsner, Michael Meyer, Henning Wiemann

Publication number: 20220376838Abstract: The present invention relates to a method in a cellular communication system, for avoiding errors in a HARQ process, wherein an NDI flag is used both for indicating either semi-persistent scheduling, SPS, activation or SPS retransmissions, and also for indicating, by toggling of the flag, a new transmission in dynamic scheduling mode. The method comprises the steps of receiving, in a scheduling message, an indication that dynamically scheduled transmission will take place; if a semi-persistent resource has occurred for the same HARQ process since a previously received indication for dynamically scheduled transmission, then considering the NDI flag to be toggled regardless of the value of the NDI flag. Thus, if the condition is fulfilled, a UE will always regard the NDI flag as indicating or requesting a new data transmission.Type: ApplicationFiled: May 24, 2021Publication date: November 24, 2022Inventors: Michael Meyer, Johan Torsner, Henning Wiemann, Magnus Stattin

Publication number: 20210385019Abstract: A method is provided in a receiving node for handling status information of data units transmitted from a sending node to the receiving node over a radio link. The receiving node detects that a number of RLC Data PDUs transmitted by the peer AM RLC entity are missing, and constructing a STATUS PDU to include NACK_SNs for a first part of the missing RLC Data PDUs and omitting NACK_SNs for the rest of the missing RLC Data PDUs. The receiving node further sets the ACK_SN field of the status PDU such that the status PDU includes only acknowledgments for PDUs having a sequence number equal to or less than the minimum sequence number omitted from the status PDU, and sends sending the STATUS PDU from the AM RLC entity to the peer AM RLC entity over the radio link.Type: ApplicationFiled: August 25, 2021Publication date: December 9, 2021Inventors: Michael MEYER, Johan TORSNER, Henning WIEMANN

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

Patent number: RE50183Abstract: Method and apparatus for conveying feedback reports from a data receiving party (300) for data received from a data sending party (302) in a wireless connection. A plurality of feedback resources (304) assigned to different feedback information codes are allocated to the data receiving party for transmitting feedback reports. After checking whether the data was received correctly or not, the data receiving party selects a feedback resource (FR2) with a feedback information code that corresponds to one or more feedback reports on the received data. The data receiving party then sends feedback information on the selected feedback resource to the data sending party, thereby conveying the corresponding feedback information code. In this way, multiple feedback reports can be conveyed in a single feedback resource to the data sending party while still retaining single carrier properties.Type: GrantFiled: October 9, 2017Date of Patent: October 22, 2024Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Tobias Tynderfeldt, David Astely, Stefan Parkvall, Per Johan Torsner
