A method for an apparatus for performing control plane measurements in a wireless device (12, 702, 850), comprising: performing, on signals received over an unlicensed spectrum across multiple sub-frames, radio resource management, RRM, measurements of a cell, wherein performing the RRM measurements includes measuring reference signal received power, RSRP, to obtain RSRP measurements associated with a first subset of the sub-frames including opportunistic transmissions and RSRP measurements associated with the second subset of the sub-frames including guaranteed transmissions, wherein opportunistic transmissions occur when a carrier or a channel meets certain conditions, wherein an opportunistic transmission is subject to a clear channel assessment, CCA, procedure or an extended CCA, E-CCA, procedure before transmission, and wherein guaranteed transmissions are guaranteed to occur at a certain time, wherein the certain time at which the guaranteed transmissions occur is a subframe for downlink clear channel assessment, CCA, exempt transmissions, D-CET; identifying a first subset of the RRM measurements associated with the first subset of the sub-frames and a second subset of the RRM measurements associated with the second subset of the sub-frames; and determining one or more RRM measurement values based on the first subset of the RRM measurements and the second subset of the RRM measurements, wherein determining the one or more RRM measurement values includes combining, into a single RSRP value, the RSRP measurements associated with the first subset of the sub-frames and the RSRP measurements associated with the second subset of the sub-frames. performing, on signals received over an unlicensed spectrum across multiple sub-frames, radio resource management, RRM, measurements of a cell, wherein performing the RRM measurements includes measuring reference signal received power, RSRP, to obtain RSRP measurements associated with a first subset of the sub-frames including opportunistic transmissions and RSRP measurements associated with the second subset of the sub-frames including guaranteed transmissions, wherein opportunistic transmissions occur when a carrier or a channel meets certain conditions, wherein an opportunistic transmission is subject to a clear channel assessment, CCA, procedure or an extended CCA, E-CCA, procedure before transmission, and wherein guaranteed transmissions are guaranteed to occur at a certain time, wherein the certain time at which the guaranteed transmissions occur is a subframe for downlink clear channel assessment, CCA, exempt transmissions, D-CET; identifying a first subset of the RRM measurements associated with the first subset of the sub-frames and a second subset of the RRM measurements associated with the second subset of the sub-frames; and determining one or more RRM measurement values based on the first subset of the RRM measurements and the second subset of the RRM measurements, wherein determining the one or more RRM measurement values includes combining, into a single RSRP value, the RSRP measurements associated with the first subset of the sub-frames and the RSRP measurements associated with the second subset of the sub-frames.
