Methods, wireless device and network node for handling signal measurements in a dynamic TDD scenario
Method and wireless device (500) for handling Channel State Information, CSI, measurements when operating in a wireless network in a dynamic Time Division Duplex, TDD, scenario where a network node (502) serving the wireless device (500) can switch between different up-link-downlink configurations comprising flexible subframes which can be uplink or downlink. When the wireless device (500) determines (5:2) that a link direction of at least one of the flexible subframes is ambiguous, the wireless device (500) indicates (5:5) to the serving network node (502) that the wireless device (500) has not made a valid CSI measurement due to the ambiguous link direction. Then, the network node (502) re-uses (5:6) a CSI measurement from a CSI report previously received from the wireless device (500), e.g. for link adaptation.
