not transmitting the S-PRS on the RB occupied by the at least one type of information in the first information set.
5. The method according to claim 1 , wherein not transmitting the S-PRS on the collided resource includes:
determining whether to transmit the S-PRS on the collided resource in a pre-configured mode or through a configuration signaling, and determining not to transmit the S-PRS on at least one of collided REs, symbols, slots, or RBs.
6. The method according to claim 4 , wherein not transmitting the S-PRS on the symbol or the slot occupied by at least one type of information in the first information set, incudes:
for a neighboring transmission reception point (TRP) or a neighboring cell, after determining a first time-frequency location on which the at least one type of information in the first information set of the neighboring TPR or neighboring cell is transmitted, not transmitting the S-PRS on a symbol or slot occupied by the first time-frequency location.
7. The method according to claim 1 , wherein the sidelink physical channel includes: at least one of a physical sidelink control channel (PSCCH), a physical sidelink feedback channel (PSFCH), or a physical sidelink broadcast channel (PSBCH);
when the resource occupied by the S-PRS collides with a resource occupied by at least one physical channel of the PSCCH, the PSFCH and the PSBCH, the S-PRS is not transmitted on the collided resource.
8. The method according to claim 1 , wherein the sidelink reference signal includes: at least one of a sidelink modulation and demodulation reference signal (SL DMRS), a sidelink channel state information reference signal (SL CSI-RS), or a sidelink phase tracking reference signal (SL PT-RS);
when the resource occupied by the S-PRS collides with a resource occupied by at least one of the SL DMRS, the SL CSI-RS and the SL PT-RS, the S-PRS is not transmitted on the collided resource.
9. A terminal, comprising: a transceiver, a processor, and a memory, wherein the memory stores a program executable by the processor to implement the step of: when a resource occupied by the sidelink positioning reference signal (S-PRS) collides with a resource occupied by at least one type of information in a first information set, not transmitting the S-PRS on the collided resource, wherein the first information set includes: at least one of a sidelink physical channel, a sidelink reference signal, a sidelink synchronization signal, a sidelink synchronization signal block (S-SSB), automatic gain control (AGC) information or guard period (GP) information;
wherein the resource includes: at least one of a resource element (RE), an OFDM symbol, a slot, or a resource block (RB);
wherein not transmitting the S-PRS on the collided resource includes not transmitting the S-PRS on the OFDM symbol.
10. The terminal according to claim 9 , wherein the resource occupied by the S-PRS colliding with the resource occupied by at least one type of information in the first information set includes:
the S-PRS and the at least one type of information in the first information set occupying at least one same resource element; or,
the S-PRS and the at least one type of information in the first information set occupying at least one same Orthogonal Frequency Division Multiplexing (OFDM) symbol.
11. The terminal according to claim 9 , wherein not transmitting the S-PRS on the collided resource further includes at least one of the following:
not transmitting the S-PRS on the RE occupied by the at least one type of information in the first information set;
not transmitting the S-PRS on the slot occupied by the at least one type of information in the first information set;
not transmitting the S-PRS on the RB occupied by the at least one type of information in the first information set.
12. The terminal according to claim 9 , wherein not transmitting the S-PRS on the collided resource includes:
