Abstract
The present disclosure relates to a method and apparatus for receiving signal, which belong to the field of a communication technology. The method comprises the following steps: determining a first frequency domain position and a second frequency domain position; determining a first frequency resource allocated for the first subcarrier spacing and a second frequency resource allocated for the second subcarrier spacing in the frequency band; receiving the signal on the first frequency resource according to the first frequency domain position, and receiving the signal on the second frequency resource according to the second frequency domain position. According to the method and apparatus, expanded service demands of a terminal can be met.

A method for receiving a signal, applied to a terminal supporting a first system signal configuration and a second system signal configuration, a first subcarrier spacing in the first system signal configuration being different from a second subcarrier spacing in the second system signal configuration, the method comprising:
- determining, according to a frequency band that the terminal supports, a first frequency domain position, corresponding to the first subcarrier spacing, of a signal to be received and a second frequency domain position, corresponding to the second subcarrier spacing, of the signal, the signal being a synchronization signal or a basic broadcast signal, wherein the determining comprises:
- shifting a preset frequency resource block located at a center frequency point of the frequency band upwardly by a first threshold corresponding to the first subcarrier spacing, to obtain a first frequency resource block, and determining the first frequency domain position of the signal according to a first positional relationship between the signal and the first frequency resource block;
- and
- shifting the preset frequency resource block downwardly by a second threshold corresponding to the second subcarrier spacing, to obtain a second frequency resource block, and determining the second frequency domain position of the signal according to a second positional relationship between the signal and the second frequency resource block;
- determining a first frequency resource allocated for the first subcarrier spacing and a second frequency resource allocated for the second subcarrier spacing in the frequency band;
- and
- receiving the signal on the first frequency resource according to the first frequency domain position, and receiving the signal on the second frequency resource according to the second frequency domain position.
An apparatus for receiving a signal, applied to a terminal supporting a first system signal configuration and a second system signal configuration, a first subcarrier spacing in the first system signal configuration being different from a second subcarrier spacing in the second system signal configuration;
- the apparatus comprising:
- a processor;
- and
- a memory storing instructions executable by the processor;
- wherein the processor is configured to:
- determine, according to a frequency band which the terminal supports, a first frequency domain position, corresponding to the first subcarrier spacing, of a signal to be received and a second frequency domain position, corresponding to the second subcarrier spacing, of the signal, the signal being a synchronization signal or a basic broadcast signal, wherein the determining comprises:
- shifting a preset frequency resource block located at a center frequency point of the frequency band upwardly by a first threshold corresponding to the first subcarrier spacing, to obtain a first frequency resource block, and determining the first frequency domain position of the signal according to a first positional relationship between the signal and the first frequency resource block;
- and
- shifting the preset frequency resource block downwardly by a second threshold corresponding to the second subcarrier spacing, to obtain a second frequency resource block, and determining the second frequency domain position of the signal according to a second positional relationship between the signal and the second frequency resource block;
- determine a first frequency resource allocated for the first subcarrier spacing and a second frequency resource allocated for the second subcarrier spacing in the frequency band;
- and
- receive the signal on the first frequency resource according to the first frequency domain position, and receive the signal on the second frequency resource according to the second frequency domain position.
