[0025] The following describes in detail the sidelink information sending method provided by the embodiment of the present application through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0026] As shown in FIG2 , an embodiment of the present application provides a sidelink information sending method 200 , which can be executed by a terminal. In other words, the method can be executed by software or hardware installed in the terminal. The method includes the following steps.

[0027] S202: The terminal determines the number or power of target first transmissions from at least one first transmission.

[0028] The first transmission mentioned in each embodiment of the present application includes but is not limited to physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH) transmission, physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH) transmission, physical sidelink control channel (Physical Sidelink Control Channel, PSSCH) transmission, SL-positioning reference signal (PRS), SL-synchronization signal block (Synchronization Signal and PBCH block, SSB), SL-channel state information reference signal (CSI-RS), SL-phase tracking reference signal (PTRS), etc., and the following is mostly explained by taking the first transmission as PSFCH transmission (abbreviated as PSFCH) as an example. Typically, each PSFCH occupies 1 common interlace and K3 dedicated physical resource blocks (PRB) (i.e., dedicated PRB).

[0029] In this embodiment, the terminal can determine the number of target first transmissions from at least one first transmission; it can also determine the power of the target first transmission from at least one first transmission; it can also determine the number and power of the target first transmission from at least one first transmission, wherein the number of target first transmissions can be less than or equal to the number of at least one first transmission, that is, the target first transmission is determined from the above-mentioned at least one first transmission.

[0030] The at least one first transmission may be a predetermined, to-be-transmitted or scheduled first transmission. For example, the number of the at least one first transmission is the number N of PSFCHs that the terminal needs to send. sch,Tx,PSFCH The at least one first transmission may also be a first transmission that is scheduled, to be transmitted, or scheduled by the terminal, determined according to the terminal capability. For example, the number of the at least one first transmission (such as PSFCH) determined may be: the maximum number of PSFCH transmissions N configured by the high-level layer. max,PSFCH .

[0031] Optionally, before the terminal determines the number or power of target first transmissions from at least one first transmission, the method further includes: when the terminal does not support sending the first transmission on a non-contiguous resource block set (RB set), the terminal determines at least one first transmission on a contiguous resource block set from at least one first transmission. The contiguous resource block set may include the first transmission with the highest priority. After the terminal determines at least one first transmission on the contiguous resource block set, the terminal determines the number or power of the target first transmission based on the at least one first transmission on the contiguous resource block set.

[0032] Optionally, the method further includes: when the number of at least one first transmission on the set of consecutive resource blocks exceeds the terminal capability, for example, exceeds the maximum number of transmissions that the terminal can send, the terminal determines, from the plurality of first transmissions on the set of consecutive resource blocks, a number not exceeding N max At least one first transmission, N max The maximum number of transmissions for the terminal, and then the number does not exceed N max The at least one first transmission of the target first transmission is determined.

[0033] Optionally, in other embodiments, the terminal is not configured with multiple first transmissions on one PRB or interlace, or is not configured with cyclic shifts of multiple first transmissions. For example, the terminal does not expect to configure multiple PSFCHs on one PRB or interlace, or does not expect to configure multiple PSFCH cyclic shifts on one PRB or interlace.

[0034] S204: The terminal sends the target first transmission based on the quantity or power of the target first transmission.

[0035] The information sending method of the side link provided in the embodiment of the present application can determine the number or power of the target first transmission from at least one first transmission, and send the target first transmission based on the determined number or power, so that the first transmission is effectively sent, thereby improving the communication performance of the side link.

[0036] In any of the above embodiments, when the first transmission is PSFCH, since different PSFCHs can be mapped to the same physical resource block (PRB) through different cyclic shifts, when calculating the power, due to the different number of PSFCHs on different PRBs, if the power of each PSFCH is accumulated, it may cause the peak to average power ratio (PAPR) of the PSFCH transmission to be too high, affecting the reception performance of the PSFCH. Therefore, the following embodiments of the present application design a power control process for the PSFCH when the power on the dedicated PRB of the PSFCH transmission is the same.

[0037] Taking into account that there is overlap in the PRBs mapped to multiple first transmissions, for example, multiple PSFCHs are mapped to the same PRB, and the power on each first PRB (such as a dedicated PRB) can be equal, the embodiment of the present application can use the following scheme to determine the number or power of the target first transmission:

[0038] Solution 1: Let the target power P on the first PRB be dedicated It is the sum of the target powers of the first transmissions on the first PRBs carrying the most or least first transmissions.

[0039] Solution 2: Let the target power P on the first PRB be dedicated It's P one , P one is the first reference power of the first transmission on a first PRB.

[0040] Solution 3: based on the priority of the first transmission, discard the first transmission with a lower priority, to ensure that there is only one first transmission on each first PRB.

[0041] Through the above solution, power control of the first transmission can be achieved, so that the first transmission is effectively sent and the communication performance of the side link is improved.
