1. A method in a User Equipment (UE) that supports configurable subcarrier spacings, comprising:
receiving a third signaling, the third signaling being used for determining a first time-frequency resource pool;
receiving a first signaling, wherein the first signaling is used for determining a subcarrier spacing corresponding to a first radio signal, or, the first signaling is used for determining a subcarrier spacing corresponding to a first radio signal and a target time-frequency resource; and
receiving the first radio signal on the target time-frequency resource, or transmitting the first radio signal on the target time-frequency resource;
wherein the target time-frequency resource belongs to a first frequency band in frequency domain; the first signaling is specific to the UE; the first time-frequency resource pool belongs to the first frequency band in frequency domain; the UE assumes that radio signals in the first time-frequency resource pool correspond to a unified subcarrier spacing; the third signaling is a broadcast signaling; the unified subcarrier spacing is configurable, the third signaling is used for determining the unified subcarrier spacing; wherein the third signaling is composed of information bits of a MIB, the subcarrier spacing corresponding to the first radio signal is a positive integral multiple of 15 kHz.
