1. An information transmission method, comprising:
in a case where first wireless transmission of a first Radio Access Techology (RAT) and second wireless transmission of a second RAT overlap in a time domain, the first RAT being one of a New Radio (NR) RAT and a Long Term Evolution (LTE) RAT, and the second RAT being the other one of the NR RAT and the LTE RAT, performing the following processing:
comparing a first priority value corresponding to the first wireless transmission of the first RAT with a second priority value corresponding to the second wireless transmission of the second RAT, and discarding the wireless transmission corresponding to a higher priority value; or, comparing the first priority value corresponding to the first wireless transmission of the first RAT with a parameter value A, in a case where the first priority value is greater than or equal to the parameter value A, discarding the first wireless transmission of the first RAT, otherwise, discarding the second wireless transmission of the second RAT, wherein the first wireless transmission comprises first wireless signal transmission and/or first wireless channel transmission, the second wireless transmission comprises second wireless signal transmission and/or second wireless channel transmission, and the first priority value is contained in control information corresponding to the first wireless transmission of the first RAT;
wherein
in a case where the second wireless transmission of the second RAT is Sidelink Synchronization Signal (SLSS) transmission, or Physical Sidelink Broadcast Channel (PSBCH) transmission, or SLSS and PSBCH block transmission, the second priority value of the second wireless transmission of the second RAT is determined according to a configuration or pre-configuration, or is a predefined value or a fixed value;
or,
in a caase where the first wireless tranmission of the first RAT is Physical Sidelink Feedback Channel (PSFCH) transmission, or, in a case where the second wireless transmission of the second RAT is PSFCH transmission, the first priority value or the second priority value is determinied according to a priority value of Physical Sidelink Shared Channel (PSSCH) trnasmission associated with the PSFCH transmission, comprising that: the first priority value or the second priority value is equal to the priority value of the associated PSSCH transmission, or, the first priority value or the second priority value is higher than or lower than the priority value of the associated PSSCH transmission by N, N being a pisitive integer, wherein a PSSCH associated with the PSFCH transmission comprises a received or send PSSCH.
