Publication number: 20210219323Abstract: A method in a user equipment for requesting that a base station schedule the user equipment for an uplink data transmission to the base station is provided. The user equipment comprises a buffer. Directly or indirectly responsive to receiving data into the buffer to be transmitted to the base station, the user equipment generates a scheduling request trigger. The scheduling request trigger is configured to trigger the sending of a scheduling request to the base station if the trigger is pending at the next scheduling request opportunity, and to remain pending until it is cancelled. The user equipment cancels the pending scheduling request trigger when the data is accounted for in a buffer status report, which reports the size of the buffer to the base station, or when the data is included directly in a scheduled uplink data transmission whichever occurs first.Type: ApplicationFiled: January 20, 2021Publication date: July 15, 2021Inventors: Jessica Östergaard, Magnus Stattin, Ghyslain Pelletier

Patent number: 9655138Abstract: In accordance with one embodiment of the present disclosure, a method of operating a relay node includes receiving information, at the relay node, information identifying a plurality of subframes. The subframes represent time periods during which a base station may grant the relay node permission to transmit to the base station on a first frequency. The method also involves selecting one of the identified subframes to be used for a transmission between the relay node and a wireless terminal on the first frequency and transmits to the wireless terminal a scheduling grant granting the wireless terminal permission to transmit information on the first frequency during the selected subframe.Type: GrantFiled: March 31, 2011Date of Patent: May 16, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Gunnar Mildh, Bogdan Timus, Jessica Östergaard, Peter Moberg

Publication number: 20160165633Abstract: A method in a user equipment for requesting that a base station schedule the user equipment for an uplink data transmission to the base station is provided. The user equipment comprises a buffer. Directly or indirectly responsive to receiving data into the buffer to be transmitted to the base station, the user equipment generates a scheduling request trigger. The scheduling request trigger is configured to trigger the sending of a scheduling request to the base station if the trigger is pending at the next scheduling request opportunity, and to remain pending until it is cancelled. The user equipment cancels the pending scheduling request trigger when the data is accounted for in a buffer status report, which reports the size of the buffer to the base station, or when the data is included directly in a scheduled uplink data transmission whichever occurs first.Type: ApplicationFiled: February 16, 2016Publication date: June 9, 2016Inventors: Jessica Östergaard, Magnus Stattin, Ghyslain Pelletier

Patent number: 9294232Abstract: The present invention relates to a method in a receiving node and a sending node of a wireless communications system for enabling and disabling integrity protection of at least one data radio bearer between the sending node and the receiving node. The method in the receiving node comprises, following a successful connection re-establishment between the sending node and the receiving node, receiving a connection reconfiguration message from the sending node, the connection reconfiguration message comprising an indicator indicating which ones of the at least one data radio bearers that shall have enabled integrity protection. It also comprises enabling integrity protection of packets on the at least one data radio bearer indicated by the indicator, and disabling integrity protection of packets on the rest of the at least one data radio bearers.Type: GrantFiled: September 16, 2011Date of Patent: March 22, 2016Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Jessica Östergaard, Gunnar Mildh

Patent number: 9173216Abstract: According to various embodiments, a method is provided at a relay node for enabling subframe allocation between a backhaul link and an access link of the relay node. The relay node is connected to a controlling entity via the backhaul link, and is connectable to at least one user equipment via the access link. The relay node receives a trigger or configuration information from the controlling entity from the controlling entity. Based on the received trigger or configuration information, the relay node sends information to the controlling entity, indicating a resource utilization of the access link and/or indicating a quality of the access link.Type: GrantFiled: April 5, 2011Date of Patent: October 27, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Peter Moberg, Gunnar Mildh, Jessica Östergaard, Håkan Persson
