1. A method in a User Equipment (UE) for wireless communication, comprising:
receiving a first radio signal from a serving cell corresponding to the user equipment; the first radio signal indicates a SLSSID(Sidelink Synchronization Sequence Identifier), and the SLSSID is used for generating a first signature sequence;
receiving a second radio signal from a communication node different from a base station maintaining the serving cell, the second radio signal includes PSS(Primary Synchronization Signal), or the second radio signal includes SSS(Secondary Synchronization Signal); and
transmitting a third radio signal on a sidelink;
wherein a receiving timing of the second radio signal is used for determining a transmitting timing of the third radio signal; the first signature sequence is used for generating the third radio signal; the first radio signal and the second radio signal are associated with a first synchronization sequence and a second synchronization sequence respectively, and the first synchronization sequence is different from the second synchronization sequence; the first synchronization sequence corresponds to a first target identifier, the second synchronization sequence corresponds to a second target identifier, and the first target identifier is different from the second target identifier; the first target identifier is a Physical Cell Identifier (PCI), the second target identifier is a Physical Cell Identifier (PCI).
