A method and an apparatus for obtaining timing advance value. The method comprises: receiving (S) a time domain signal, which contains at least part of a reference signal; extracting (SI), from the time domain signal, a first group of signal parts including at least one signal part, and a second group of signal parts including at least one signal part, wherein the first group of signal parts do not overlap the second group of signal parts; and determining (S) a timing advance, TA, value based on an energy of a signal part in the first group of signal parts and an energy of a signal part in the second group of signal parts, wherein the energy of the signal part is based on correlation between the signal part and the reference signal. Therefore, the TA value may be obtained based on a time domain signal.

Method and apparatus for obtaining timing advance value

A method performed by a communication node and an apparatus for operating the method are proposed. The method includes obtaining matched filter channel estimation associated with a user equipment (UE); obtaining first Timing Advance (TA) compensated channel estimation; obtaining first noise suppressed channel estimation; and obtaining first TA estimation associated with the UE based on the first noise suppressed channel estimation.

Method and apparatus for estimating and compensating timing advance

Provided are a method and device for three-dimensional channel measurement resource configuration and quality measurement, which relate to the field of wireless communications and are used for solving the problem of how to perform three-dimensional channel quality measurement. In the present invention, a base station selects a channel quality measurement resource used for three-dimensional channel measurement from channel quality measurement resources preconfigured for a terminal, and sends indication information about the selected channel quality measurement resource to the terminal; the terminal receives the indication information, and performs three-dimensional channel quality measurement on corresponding channel quality measurement resources, thereby solving the problem of how to perform three-dimensional channel quality measurement.
