DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, the embodiments of the present application will be described in detail with reference to the drawings. Estimation of the location of the initial path plays an important role in signal synchronization and signal transmission time estimation. In the related art, there are two ways to improve the estimation accuracy of the location of the initial path. The first is to improve the estimation accuracy by the algorithm of the receiving side. The second is to improve the bandwidth of the signal. The former method can improve the accuracy of searching the location of the initial path, but the time resolution cannot be improved because the time resolution depends on the bandwidth of the signal. Therefore, the latter method improves the time resolution by improving the bandwidth of the signal. However, due to the influence of factors such as terminal capability and interference coordination, the available continuous frequency domain units of the signal are limited, which further affects the estimation accuracy of the location of the initial path. The present application aims to provide frequency domain units having a related relationship for improving the estimation accuracy of channel features by jointly estimating channel characteristics.

There is a relationship between the frequency domain units, and such a relationship between the frequency domain units may indicate that two frequency domain units have a relationship when configuring a frequency domain unit set, in which case the reference signal resources respectively configured in the two frequency domain units have a relationship. The relationship between the frequency domain units may be such that the frequency domain units corresponding to the reference signal resources having a relationship have a relationship after the reference signal resources configured in the frequency domain unit have a relationship. And, when it is indicated that two frequency domain units have a relationship, the same reference signal resource pool can be configured in the two frequency domain units.
