interface; the other is the uplink/downlink communication mode between the
terminal and the base station, where the air interface between the terminal and
the base station is called Uu interface.
Chapter 5 specifies the technical requirements for the PC5 interface of the LTE-
based wireless communication technology for vehicular networking. The
sidelink's communication method includes two transmission modes. Among
them, the sidelink transmission mode 3 is resource scheduling allocation, whilst
the sidelink transmission mode 4 is the UE's independent resource selection.
For specific definitions, see 7.2.2 of YD/T 3340-2018 Technical requirements of
air interface of LTE-based vehicular communication.

5.1.1.2.5 Resource pool
The 5.1.3 defines the subframe pool and resource block pool.
For PSSCH, the current time slot number in the subframe pool is
, where is the current time slot number in the
current sidelink subframe , where k is equal to the footnote of
; is defined by the sidelink transmission mode 3 in 5.1.3.2.1.2, or defined
by the sidelink transmission mode 4 in 5.1.3.2.1.3.
5.1.1.2.6 Guard interval
The last SC-FDMA symbol of the sidelink subframe is used as a guard interval
and cannot be used for sidelink transmission.
5.1.1.3 Physical shared channel of sidelink
5.1.1.3.1 Scrambling
The bit block (where Mbit is the number of bits sent)
transmitted on the PSSCH in a subframe shall be scrambled according to 5.3.1
of 3GPP TS 36.211 (Release 14).
The scrambling sequence shall be initialized at the beginning of each PSSCH
subframe according to , where for the sidelink
transmission mode 3 and the sidelink transmission mode 4, p and L are given
by 5.1.1 of 3GPP TS 36.212 (Release 14), is equal to the decimal
representation of the CRC check code of the PSCCH as sent in the same
subframe as the PSSCH.
5.1.1.3.2 Modulation
The modulation is performed according to 5.3.2 of 3GPP TS 36.211 (Release
14). The modulation mode of PSSCH is as shown in Table 3.
3GPP TS 36.211 (Release 14). For the sidelink transmission mode 3 and the
sidelink transmission mode 4, it is assumed that the sequence is generated
according to subframe 5.
Resource unit mapping: The sequence di(n) is multiplied by the amplitude
scaling factor to adjust the transmit power defined in 5.1.3.4; then
mapped to the resource element in the second time slot of the subframe on the
antenna port 1020. The mapping ......
