Sidelink communication method, terminal apparatus, and system

A communication apparatus, comprising:

• at least one processor configured to:
• determine a first moment;
• obtain first configuration information;
• and
• determine, based on the first configuration information, at least two candidate resources in a first slot, wherein each of the at least two candidate resources includes a plurality of consecutive symbols including at least one first symbol and at least one second symbol, the at least one first symbol in each of the at least two candidate resources is usable to transmit first information, the at least one second symbol in each of the at least two candidate resources is usable to transmit sidelink control information, and the first symbol precedes the second symbol.
