A method, comprising: receiving (1302) a first reference signal, RS, for tracking according to a first channel status information RS pattern, CSI-RS, the first CSI-RS pattern specifying: a first resources of the first RS, where the first resources consist of resources of four single-port CSI-RSs, the resources of the four single-port CSI-RSs are located in two consecutive slots, and each slot corresponds to resources of two of the four single port CSI-RS; and a first quasi-co-location setting, QCL, comprising a first set of QCL parameters, the first QCL setting indicating that the first RS has a QCL relationship with a first demodulation reference signal, DMRS, with respect to to the first set of QCL parameters. |
