[0072] The information transmission method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and application scenarios.

[0073] As shown in Figure 2 The embodiments of the present application provide an information transmission method, including:

[0074] Step 201: The terminal occupies the resource of the first information on an unlicensed frequency band or a shared frequency band, and / or transmits the first information.

[0075] The first information includes at least one of the following:

[0076] The first item: N1 first SL information in frequency division multiplexing (FDM), N1>1;

[0077] The second item: N first information in FDM, N first information including N2 first SL information and N-N2 second information, N>1, N2≥1;

[0078] The third item: first SL information transmitted according to a first parameter;

[0079] The fourth item: first SL information transmitted within a first preset time, at least one first transmission existing within the first preset time;

[0080] The first SL information includes a synchronization signal, broadcast information or a synchronization signal block.

[0081] Optionally, the first information satisfies a first transmission requirement, and / or the first transmission satisfies the first transmission requirement.

[0082] Optionally, at least one of the first information and the second information satisfies the first transmission requirement, for example, a bandwidth span occupied by the N1 first SL information is greater than or equal to a preset percentage of a nominal channel bandwidth; or a bandwidth span occupied by the first SL information and the second information is greater than or equal to a preset percentage of the nominal channel bandwidth; or a bandwidth span occupied by the first transmission is greater than or equal to a preset percentage of the nominal channel bandwidth.

[0083] The N, N1 and N2 are determined according to the first transmission requirement.

[0084] Here, the first information is information satisfying a specific condition, for example, the first information itself satisfies the first transmission requirement, or the first information and the first transmission satisfying the first transmission requirement are jointly transmitted within the first preset time. In addition, it should be noted that the synchronization signal and the broadcast information can satisfy the same or different conditions. For example, the synchronization signal is a synchronization signal transmitted according to the first parameter, and the broadcast information is broadcast information transmitted within the first preset time.

[0085] In addition, the N1 first SL information in frequency division multiplexing can also be described as time domain overlap of N1 first SL information; and the N first information in FDM can also be described as time domain overlap of N first information.

[0086] Optionally, the first transmission requirement can be OCB, and can also be other transmission requirements. The following content of the present application is exemplified by taking the first transmission requirement as OCB. OCB refers to, in the unlicensed frequency band, when a device transmits a signal in the occupied resource, the frequency domain span of the power distribution in a nominal channel bandwidth (for example, 20 MHz or 10 MHz, the bandwidth is different in different countries and regions) needs to be ensured to be not less than a preset percentage of the nominal channel bandwidth, for example, the frequency domain span of 99% of the power distribution in the nominal channel bandwidth is not less than 80% of the nominal channel bandwidth. For example, the bandwidth occupied by the FDM N1 first SL information in the unlicensed frequency band or the shared frequency band is greater than or equal to 80% of the unlicensed frequency band; the bandwidth occupied by the FDM N first information in the unlicensed frequency band or the shared frequency band is greater than or equal to 80% of the unlicensed frequency band.

[0087] In the embodiments of the present application, the resources of the first information are preempted in the unlicensed frequency band or the shared frequency band, and / or the first information is transmitted, the first information being SL information satisfying a specific condition, for example, the FDM N1 first SL information, for example again, the first SL information transmitted according to the first parameter; for example again, the first SL information transmitted in the first preset time, at least one first transmission existing in the first preset time; the FDM N first information. The above-mentioned first information satisfying the specific condition can satisfy the first transmission requirement by itself, or is SL information transmitted together with the first transmission satisfying the first transmission requirement, so that the first information satisfying the specific condition can satisfy the first transmission requirement, such as OCB requirement, when being transmitted in the unlicensed frequency band or the shared frequency band.

[0088] For the above-mentioned first item: the FDM N1 first SL information is transmitted or repeated to ensure that the OCB is satisfied. That is, the frequency domain span of the N1 first SL information (for example, the span between the first SL information of the highest frequency domain and the first SL information of the lowest frequency domain, or the span between certain two first SL information) is ensured to satisfy the OCB.

[0089] Optionally, the method of the embodiments of the present application further comprises:

[0096] N;

[0097] N2;

[0098] G2, G2 is a frequency domain interval between any or specific adjacent first information in the N information, for example, G2 is a frequency domain interval between any or specific adjacent two first SL information, or, G2 is a frequency domain interval between any or specific adjacent second information, or, G2 is a frequency domain interval between any or specific adjacent first SL information and second information;

[0099] a frequency domain location of the second information;

[0125] Or, at least M first SL information in the N1 first SL information is at least partially different, M > 1.

[0126] For example, the sequence of the M first SL information is different or the content carried is different.

[0127] When the N1 first SL information is N1 same first SL information, transmitting the N1 broadcast channels can be interpreted as repeating mapping the physical sidelink broadcast channel (PSBCH) N1 times in the frequency domain.

[0128] Wherein, please refer to Table 1 for some possible values of N1. Wherein, it is assumed that the bandwidth corresponding to the first SL information is 11 RB.
