Abstract:
The disclosure provides for control plane measurements in a wireless device. The wireless device may measure, across multiple sub-frames received over an unlicensed spectrum, received cell-specific reference signals (CRS) from a cell to obtain CRS measurements. The wireless device may identify one or both of a first subset of the CRS measurements associated with a first subset of the sub-frames including opportunistic transmissions and a second subset of the CRS measurements associated with a second subset of the sub-frames including guaranteed transmissions. The wireless device may compute one or both of a first signal to interference plus noise ratio (SINR) value for the first subset of the CRS measurements and a second SINR value for the second subset of the CRS measurements. The wireless device may monitor a radio link condition of the wireless device based at least in part on the first SINR value or the second SINR value.
