Patent number: 11949519Abstract: A wireless communication system includes one or more base stations, and one or more user devices, UEs. The base station transmits data to a UE being served by the base station, the data including control data and user data, the user data including at least first user data and second user data, the first user data associated with a first service and second data associated with second service, the first and second services having one or more different transmission requirements. Responsive to receiving in the control data a grant for a feedback transmission, the UE sends a feedback to the base station, the feedback indicating for one or more data blocks of the data a successful or non-successful reception at the UE. The control data includes a first downlink assignment index (DAI) associated with the first data, and a second DAI associated with the second data.Type: GrantFiled: March 4, 2021Date of Patent: April 2, 2024Assignee: Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventors: Thomas Fehrenbach, Cornelius Hellge, Baris Göktepe, Thomas Wirth, Thomas Schierl

Patent number: 11950326Abstract: A wireless communication system includes one or more base stations, and a plurality of UEs for a sidelink communication using sidelink resources. The UEs includes a transmitting UE and a receiving UE using a subset of the sidelink resources of the wireless communication system. The receiving UE sends over the sidelink a sidelink feedback to the transmitting UE. The sidelink feedback indicates for a data transmission a successful or non-successful reception at the receiving UE. The transmitting UE reports the sidelink feedback to a base station. The base station provides to the transmitting UE, responsive to the sidelink feedback, sidelink resources for a possible retransmission of a data packet over the sidelink to the receiving UE. The reporting of the sidelink feedback to the base station by the transmitting UE is activated or deactivated responsive to one or more conditions.Type: GrantFiled: July 8, 2021Date of Patent: April 2, 2024Assignee: Koninklijke Philips N.V.Inventors: Sarun Selvanesan, Thomas Fehrenbach, Roya Ebrahim Rezagah, Cornelius Hellge, Thomas Wirth, Thomas Schierl, Robin Thomas, Baris Göktepe
