A method at network node in a wireless communication network comprising: determining composite dynamic subframe, CDS, information, for a first Time Division Duplex, TDD, carrier frequency used by one or more TDD carriers transmitted by a respective one or more cells in the network, said CDS information indicating that one or more subframes in one or more of the TDD carriers are dynamic subframes having a dynamically changeable uplink or downlink direction; and sending the CDS information to a wireless device operating in the network, for use by the wireless device in performing radio measurements with respect to the dynamic subframes in the one or more TDD carriers, characterized in that the CDS information sent to the wireless device comprises: an indication as to which subframes are dynamic subframes; an indication as to which subframes are not dynamic subframes; and for a case where the one or more TDD carriers comprise a serving cell carrier for the wireless device and one or more neighboring-cell carriers, an indication as to whether the dynamic subframes are the same as between the serving-cell carrier and the one or more neighboring-cell carriers, wherein radio measurements should not be performed on the subframes which are indicated as dynamic subframes and dynamic subframes which are the same between the serving-cell carrier and the one or more neighboring-cell carriers. determining composite dynamic subframe, CDS, information, for a first Time Division Duplex, TDD, carrier frequency used by one or more TDD carriers transmitted by a respective one or more cells in the network, said CDS information indicating that one or more subframes in one or more of the TDD carriers are dynamic subframes having a dynamically changeable uplink or downlink direction; and sending the CDS information to a wireless device operating in the network, for use by the wireless device in performing radio measurements with respect to the dynamic subframes in the one or more TDD carriers, characterized in that the CDS information sent to the wireless device comprises: an indication as to which subframes are dynamic subframes; an indication as to which subframes are not dynamic subframes; and for a case where the one or more TDD carriers comprise a serving cell carrier for the wireless device and one or more neighboring-cell carriers, an indication as to whether the dynamic subframes are the same as between the serving-cell carrier and the one or more neighboring-cell carriers, wherein radio measurements should not be performed on the subframes which are indicated as dynamic subframes and dynamic subframes which are the same between the serving-cell carrier and the one or more neighboring-cell carriers. an indication as to which subframes are dynamic subframes; an indication as to which subframes are not dynamic subframes; and for a case where the one or more TDD carriers comprise a serving cell carrier for the wireless device and one or more neighboring-cell carriers, an indication as to whether the dynamic subframes are the same as between the serving-cell carrier and the one or more neighboring-cell carriers, wherein radio measurements should not be performed on the subframes which are indicated as dynamic subframes and dynamic subframes which are the same between the serving-cell carrier and the one or more neighboring-cell carriers.
