Embodiment approach 230
[0062] At block 230, the communications device 102 obtains a channel estimate and an estimate of a covariance matrix of interference and noise based on the N parts into which each reference signal time domain symbol in the set is divided. For purposes of example and not limitation, the Figure 4 An example implementation 230' of block 230 is shown in .
[0063] In this example implementation, at block 231, the communication device 102 may, for each reference signal time-domain symbol in the set, respectively perform a time-frequency transformation of length L / N on the corresponding N parts (e.g., discrete Fourier transform Transform (DFT) or Fast Fourier Transform (FFT)) to obtain N signal sequences. Among them, L represents the length of the normal time-frequency transformation determined by the system bandwidth. The embodiments are described below using DFT as an example of time-frequency transformation, however, it should be understood that FFT and other time-frequency tr...
