Patent number: 11184787Abstract: According to certain embodiments, a method in a wireless device is provided that includes receiving, from a network node, dynamic allocation signaling to commence measurement on a semi-persistent CSI-RS resource. A first measurement is performed on the CSI-RS resource. A first CSI report based only on the first measurement is transmitted to the network node. A trigger message is received from the network node that is different from the dynamic allocation signaling. The trigger message triggers semi-persistent CSI reporting, and the wireless device initiates semi-persistent reporting.Type: GrantFiled: January 8, 2018Date of Patent: November 23, 2021Assignee: Telefonaktiebolaget LM Ericcson (publ)Inventors: Siva Muruganathan, Mattias Frenne, Shiwei Gao, Stephen Grant, Robert Mark Harrison
