FIELD: communications.
SUBSTANCE: technical result consists in the reliability of the transmission of a direct connection. This is implemented by defining a third transmission resource, the third transmission resource contains a transmission resource for transmitting a Physical Sidelink Shared Channel (PSSCH); determining a second transmission resource in a third transmission resource, the second transmission resource contains a time domain resource that is the same as and/or adjacent to the time domain resource for the demodulation reference signal (DMRS) PSSCH, and the second transmission resource is used to transmit the second direct connection control information (SCI), and the third transmission resource further contains a first transmission resource for transmitting the first SCI; and mapping the second SCI on the second transmission resource in the following order: first the frequency domain and then the time domain.
EFFECT: reliability of the transmission of a direct connection.
