[0023] Next, with reference to the accompanying drawings, the method for sending sidelink information provided in the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0024] As Figure 2 shown, the embodiments of the present application provide a method 200 for sending sidelink information. This method can be executed by a terminal. In other words, this method can be executed by software or hardware installed in the terminal. The method includes the following steps.

[0025] S202: The terminal determines the number or power of the target first transmission from at least one first transmission.

[0026] The first transmission mentioned in various embodiments of the present application includes but is not limited to Physical Sidelink Feedback Channel (PSFCH) transmission, Physical Sidelink Shared Channel (PSSCH) transmission, Physical Sidelink Control Channel (PSSCH) transmission, SL - Positioning Reference Signal (PRS), SL - Synchronization Signal and PBCH block (SSB), SL - Channel State Information Reference Signal (CSI - RS), SL - Phase - tracking reference signal (PTRS), etc. Subsequently, the PSFCH transmission is usually taken as an example for illustration. Generally, each PSFCH occupies 1 common interlace and K3 dedicated Physical Resource Blocks (PRBs).

[0027] 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; or it can determine both the number and power of the target first transmission from at least one first transmission. Here, 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.

[0028] The above - mentioned at least one first transmission can be a predetermined, to - be - transmitted, or scheduled first transmission. For example, the number of at least one first transmission is the number N of PSFCHs that the terminal needs to send. sch,Tx,PSFCH The above - mentioned at least one first transmission can also be determined by the terminal according to its capabilities among the predetermined, to - be - transmitted, or scheduled first transmissions. For example, the number of at least one first transmission (such as PSFCH) determined can be: the maximum number N of PSFCH transmissions configured by the higher layer. max,PSFCH .

[0029] Optionally, before the terminal determines the number or power of the target first transmission from at least one first transmission, the method further includes: when the terminal does not support sending the first transmission on a discontinuous resource block set (RB set), the terminal determines at least one first transmission on a continuous resource block set from at least one first transmission. The above continuous resource block set may include the first transmission with the highest priority. After the terminal determines at least one first transmission on the continuous resource block set, it then determines the number or power of the target first transmission according to at least one first transmission on the continuous resource block set.

[0030] Optionally, the method further includes: when the number of at least one first transmission on the continuous resource block set exceeds the terminal capability, for example, exceeds the maximum transmission number that the terminal can send, the terminal determines at least one first transmission with a number not exceeding N max from multiple first transmissions on the continuous resource block set, where N max is the maximum transmission number of the terminal, and then determines the number or power of the target first transmission according to at least one first transmission with a number not exceeding N max .

[0031] Optionally, in other embodiments, the terminal will not be configured with multiple first transmissions or multiple cyclic shifts of the first transmission on one physical resource block (PRB) or interlace. For example, the terminal does not expect to configure multiple physical side link feedback channels (PSFCHs) on one PRB or interlace, or does not expect to configure multiple cyclic shifts of PSFCHs on one PRB or interlace.

[0032] S204: The terminal sends the target first transmission based on the number or power of the target first transmission.

[0033] In the side link information sending method provided in the embodiments of the present application, the terminal 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, improving the communication performance of the side link.

[0034] In any of the above embodiments, when the first transmission is a 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 numbers of PSFCHs on different PRBs, if the power of each PSFCH is accumulated, it may lead to an excessive Peak to Average Power Ratio (PAPR) of the PSFCH transmission, affecting the reception performance of the PSFCH. Therefore, in the following embodiments of the present application, a power control process of the PSFCH is designed when the power on the dedicated PRB for PSFCH transmission is the same.

[0035] Considering that the PRBs mapped by multiple first transmissions overlap. For example, multiple PSFCHs are mapped to the same PRB, and the power on each first PRB (such as the dedicated PRB) can be equal. The embodiments of the present application can adopt the following scheme to determine the number or power of the target first transmission:

[0036] Solution 1: Let the target power P on a first PRB dedicated be the sum of the target powers of the first transmissions on the first PRB that carries the most or the least number of first transmissions.

[0037] Solution 2: Let the target power P on a first PRB dedicated be P one and P one be the first reference power of the first transmission on a first PRB.

[0038] Solution 3: Discard the first transmissions with lower priorities according to the priority of the first transmissions to ensure that there is only one first transmission on each first PRB.

[0039] Through the above solutions, power control of the first transmission can be achieved, enabling the first transmission to be effectively sent and improving the communication performance of the sidelink.

[0040] The above three solutions will be introduced in detail below.

[0041] First, Solutions 1 and 2 will be described.

[0042] Optionally, when the terminal determines the number or power of the target first transmission from at least one first transmission, it includes: when the terminal is configured with path loss parameters and meets one of the following conditions, the terminal determines the number or power of the target first transmission from at least one first transmission:

[0044] 2) The power of X1 Ps dedicated and the power of X2 Ps common exceed P CMAX .

[0045] Wherein, X1 is the number of first PRBs occupied by at least one first transmission, X2 is the number of second PRBs occupied by at least one first transmission, P dedicated is the power of the first transmission on one first PRB, P common is the power of the first transmission on one second PRB. The first PRB is used to carry target information. For example, the first PRB is a dedicated PRB, and the second PRB does not carry target information. For example, the second PRB is a common PRB, a common interlace PRB.

[0046] Optionally, in one embodiment, for example, in the case where the power of X1 Ps dedicated and the power of X2 Ps common do not exceed P CMAX , the number or power of the determined target first transmissions of the terminal satisfies at least one of the following:

[0047] 1) The number N Tx of the target first transmissions is the number of at least one first transmission.

[0048] 2) The power P k,dedicated of one target first transmission on one first PRB is determined according to P dedicated or the third value X3. The third value is the number of target first transmissions on the first PRB where the target first transmission is located.

[0049] For example, P k,dedicated = P dedicated - 10log 10 (X3) [dB].[[]END]]

[0050] 3) The power P k,common of one target first transmission on one second PRB is P common .

[0051] 4) The power P dedicated of the target first transmission on one first PRB is P dedicated .

[0053] 6) The power P of a target first transmission k is the sum of K3 Ps k,dedicated power and X2 Ps k,common power, where K3 is the number of first PRBs occupied by a target first transmission.

[0054] Optionally, in one embodiment, for example, in the case where the sum of X1 Ps dedicated power and X2 Ps common power exceeds P CMAX , the number or power of the target first transmission determined by the terminal satisfies at least one of the following:

[0055] 1) The number N of target first transmissions Tx is determined according to the priority of the first transmission, and the N Tx is greater than or equal to where M i is the number of first transmissions with priority i or priority i - 8, and K is the maximum value that satisfies the sum of X4 Ps dedicated power and X5 Ps common power does not exceed P CMAX , X4 is the number of first PRBs occupied by a first transmission, and X5 is the number of second PRBs occupied by a first transmission.

[0056] Optionally, X5 is determined after the second PRB discard process is performed among a first transmission.

[0057] Optionally, if the terminal does not support the first transmission in a non - contiguous RB set, the terminal determines N Tx target first transmissions according to the priority of the first transmission, and the N Tx target first transmissions are located on a contiguous RB set, and the contiguous RB set includes the first transmission with the highest priority.

[0058] For example, the terminal needs to select N Tx target first transmissions (such as PSFCH), and the N Tx is greater than or equal to If PSFCHs are located on a contiguous RB set, the terminal can freely select N Tx (including at least PSFCHs); if PSFCHs are located on a non - contiguous RB set, the terminal needs to additionally select some PSFCHs so that the total N TxOne PSFCH is located on consecutive RB sets.

[0059] 2) The power P of a target first transmission on a first PRB k,dedicated is determined according to min(P′ dedicated , P dedicated ), or a third value X3, where P′ dedicated satisfies that the sum of X6 P′ dedicated and X7 P′ common is equal to P CMAX , X6 is the number of first PRBs occupied by N Tx target first transmissions, X7 is the number of second PRBs occupied by N Tx target first transmissions, and P′ common is determined according to P′ dedicated or a first offset P offset , or is determined according to P′ dedicated,one or a first offset P offset .

[0060] Optionally, X7 is X5, or X7 is determined after performing a second PRB discarding process among N Tx target first transmissions.

[0061] For example, P k,dedicated = min(P′ dedicated , P dedicated ) - 10log 10 (X3), where This is one form of formula expression, and it does not exclude other writing methods through formula transformation.

[0062] 3) The power P of a target first transmission on a second PRB k,common is P′ common .

[0063] 4) The power P of the target first transmission on a first PRB dedicated is min(P′ dedicated , P dedicated ) or is min(P′ dedicated,one , P dedicated,one ).

[0065] 6) The power P of a target first transmission k is the sum of the powers of K3 P k,dedicated and X7 P k,commonThe sum of powers, and K3 is the number of first PRBs occupied by a target first transmission.

[0070] 2) P common Determined according to P dedicated Or a first offset P offset Determined.

[0073] For example, P common = P dedicated - 10log 10 (X1′)- P offset [dB], where X1′ is the number of first transmissions on the first PRB carrying the most or fewest first transmissions or the number of first transmissions on the first PRB where the first transmission with the highest priority is located.

[0074] 4) X2 is determined after the second PRB discard process is performed in at least one first transmission.

[0075] Wherein, PRB discard means that if there are a first PRB and a second PRB simultaneously within 1 MHz, the second PRB needs to be discarded.

[0076] The above embodiments of Solution 1 are applicable when the path loss parameter is configured in the terminal. When the path loss parameter is not configured in the terminal, the number or power of the determined target first transmissions of the terminal satisfies at least one of the following:

[0077] 1) The number N of target first transmissions Tx is determined according to the priority of the first transmission, and the N Tx is greater than or equal to 1.

[0079] 2) The power P of a target first transmission on a first PRB k,dedicated is determined according to min(P′ dedicated , P dedicated ) or a third value X3. Among them, P′ dedicated satisfies that the sum of X8 P′ dedicated and X9 P′ common is equal to P CMAX , X8 is the number of first PRBs occupied by N Tx target first transmissions, X9 is the number of second PRBs occupied by N Tx target first transmissions, and P′ common is determined according to P′ dedicated or a first offset P offset , or determined according to P′ dedicated,one or a first offset P offset .

[0080] Optionally, X7 is determined after the second PRB discard process is performed among N Tx,PSFCH target first transmissions.

[0081] For example, P k,dedicated = min(P′ dedicated , P dedicated ) - 10log 10 (X3), where This is one form of formula expression, and other writing forms are not excluded through formula transformation.

[0082] 3) The power P of a target first transmission on a second PRB k,common is P' common .

[0118] Optionally, if the terminal does not support first transmissions in a discontinuous RB set, the terminal determines N Tx target first transmissions according to the priority of the first transmission, and the N Tx target first transmissions are located on a continuous RB set, and the continuous RB set includes the first transmission with the highest priority.

[0119] 2) The power P of a target first transmission on a first PRB k,dedicated is determined according to min(P′, P one ), where P′ satisfies that the sum of Y8 P′s and Y9 P′s common is equal to P CMAX , Y8 is the number of first PRBs occupied by N Tx target first transmissions, Y9 is the number of second PRBs occupied by N Tx target first transmissions, and P′ common is determined according to P′ or a first offset P offset .

[0120] Optionally, Y7 is determined after performing a second PRB discarding process among N Tx target first transmissions.

[0121] For example, P k,dedicated = min(P′ dedicated , P dedicated ) - 10log 10 (X3), where This is one form of formula expression, and it does not exclude other writing methods through formula transformation.

[0122] For example, P k,dedicated = min(P′, P one ), where

[0127] The above implementation can be applied to the case where the PRBs mapped by multiple first transmissions overlap and the powers on each first PRB (such as dedicated PRB) are equal

[0128] In addition, considering that if the PRBs mapped by multiple first transmissions overlap, the powers on each first PRB (such as dedicated PRB) may not need to be equal, that is, the case where they can be accumulated. The following will introduce how the terminal determines the number or power of the target first transmission from at least one first transmission

[0129] Optionally, the terminal determines the number or power of the target first transmission from at least one first transmission, including: when the terminal is configured with path loss parameters and meets one of the following conditions, the terminal determines the number or power of the target first transmission from at least one first transmission

[0130] 1) The sum of the powers of Z1 Ps dedicated and the powers of Z2 Ps common does not exceed P CMAX .

[0131] 2) The sum of the powers of Z1 Ps dedicated and the powers of Z2 Ps common exceeds P CMAX .

[0132] Where Z1 is the number of at least one first transmission multiplied by the number of first PRBs occupied by a first transmission, Z2 is the number of second PRBs occupied by at least one first transmission (such as K3), and P dedicatedis the power of a first transmission on a first PRB (which can also be described as a first transmission resource, such as a combination of a PRB and a cyclic shift), P common is the power of the first transmission on a second PRB, where the first PRB is used to carry target information. For example, the first PRB is a dedicated PRB, and the second PRB does not carry target information. For example, the second PRB is a common PRB, a common interlace PRB.

[0133] Optionally, in an embodiment, for example, among Z1 Ps dedicated power and Z2 Ps common the sum of the powers does not exceed P CMAX in which case, the number or power of the target first transmission determined by the terminal satisfies at least one of the following:

[0138] 5) The power P of the target first transmission on a second PRB common is P common .

[0139] 6) The power P of a target first transmission k is the sum of K3 Ps k,dedicated power and Z2 Ps k,common power, where K3 is the number of first PRBs occupied by a target first transmission.

[0140] Optionally, in an embodiment, for example, among Z1 Ps dedicated power and Z2 Ps common the sum of the powers exceeds P CMAX in which case, the number or power of the target first transmission determined by the terminal satisfies at least one of the following:

[0141] 1) The number N of the target first transmissionTx Determined according to the priority of the first transmission, the N Tx greater than or equal to where M i is the number of first transmissions with priority i or priority i - 8, and K is the maximum value that satisfies the sum of the powers of Z4 P dedicated and the powers of Z5 P common does not exceed P CMAX , Z4 is the number of first transmissions multiplied by the number of first PRBs occupied by one first transmission, and Z5 is the number of second PRBs occupied by one first transmission.

[0142] Optionally, Z5 is determined after performing the second PRB discard process among the first transmissions.

[0143] Optionally, if the terminal does not support the first transmission in a discontinuous RB set, the terminal determines N Tx target first transmissions according to the priority of the first transmission, and the N Tx target first transmissions are located on a continuous RB set, and the continuous RB set includes the first transmission with the highest priority.

[0144] For example, the terminal needs to select N Tx target first transmissions (such as PSFCH), and the N Tx is greater than or equal to If the PSFCHs are located on a continuous RB set, the terminal can freely select N Tx,PSFCH (including at least PSFCHs); if the PSFCHs are located on a discontinuous RB set, the terminal needs to additionally select some PSFCHs so that the total N Tx PSFCHs are located on a continuous RB set.

[0145] 2) The power P of a target first transmission on a first PRB k,dedicated is determined according to min(P′ dedicated , P dedicated ), where P′ dedicated satisfies that the sum of the powers of Z6 P′ dedicated and Z7 P′ common is equal to P CMAX , Z6 is N Tx multiplied by K3, Z7 is the number of second PRBs occupied by N Tx target first transmissions, and P′ common is determined according to P′ dedicatedor the first bias P offset determined, or according to P′ dedicated,one or the first bias P offset determined.

[0146] Optionally, Z7 is Z5, or Z7 is determined after performing a second PRB discard process in N Tx, target first transmissions. For example, P k,dedicated = min(P′ dedicated , P dedicated ), where This is one form of formula expression, and other writing methods are not excluded through formula transformation.

[0147] 3) The power P of a target first transmission on a second PRB k,common is P′ common .

[0148] 4) The power P of the target first transmission on a first PRB dedicated is Z8 times P k,dedicated , where Z8 is the number of the target first transmissions on the first PRB.

[0149] 5) The power P of the target first transmission on a second PRB common is P′ common .

[0150] 6) The power P of a target first transmission k is the sum of the power of K3 times P k,dedicated and the power of Z7 times P k,common , where K3 is the number of the first PRBs occupied by a target first transmission, and Z7 is the number of the second PRBs occupied by N Tx target first transmissions.

[0151] The above-mentioned multiple embodiments satisfy at least one of the following:[[]]

[0152] 1) P dedicated is determined according to P one or the first value, and the first value is the number of the first transmissions on the first PRB carrying the most or fewest first transmissions. For example, when the first transmission is PSFCH, PSFCH is mapped on the same PRB with different cyclic displacements.

[0153] For example, P dedicated = P one - 10log 10 (X1) [dB].[[]]

[0154] For example, P dedicated = P one .

[0155] 2) P common Determined according to P dedicated or the first offset P offset Determine.

[0156] For example, P common = P dedicated - P offset [dB].

[0157] For example, P common = P dedicated + 10log 10 (X1) - P offset [dB].

[0158] 3) P common Determined according to P dedicated,one or the first offset P offset Determine, P dedicated,one is the target power of the first transmission on the first PRB carrying the most or least first transmissions or the target power of the first transmission with the highest priority.

[0159] For example, P common = P dedicated,one + 10log 10 (X1') - P offset [dB], where X1' is the number of first transmissions on the first PRB carrying the most or least first transmissions or the number of first transmissions on the first PRB where the first transmission with the highest priority is located

[0160] For example, P common = P dedicated,one - P offset [dB], where P dedicated,one = P one or P one - 10log 10 (X1').

[0161] 4) Z2 is determined after performing the second PRB discard process in at least one first transmission.

[0162] PRB discard means that if there are both a first PRB and a second PRB within 1 MHz, the second PRB needs to be discarded.

[0163] The above embodiments are applicable when the path loss parameter is configured in the terminal. When the path loss parameter is not configured in the terminal, the number or power of the target first transmission determined by the terminal satisfies at least one of the following:

[0164] 1) The number N of the target first transmissions TxDetermined according to the priority of the first transmission, the N Tx is greater than or equal to 1.

[0165] Optionally, if the terminal does not support the first transmission in a discontinuous RB set, the terminal determines N Tx target first transmissions according to the priority of the first transmission, and the N Tx target first transmissions are located on a continuous RB set, and the continuous RB set includes the first transmission with the highest priority.

[0166] 2) The power P of a target first transmission on a first PRB k,dedicated is determined according to min(P′ dedicated , P dedicated ), where P′ dedicated satisfies that the sum of Z9 P′ dedicated and Z10 P′ common is equal to P CMAX , Z9 is N Tx multiplied by K3, Z10 is the number of second PRBs occupied by N Tx target first transmissions, and P′ common is determined according to P′ dedicated or the first bias P offset , or is determined according to P′ dedicated,one or the first bias P offset .

[0167] Optionally, Z10 is determined after performing the second PRB discard process among N Tx target first transmissions.

[0168] For example, P k,dedicated = min(P′ dedicated , P dedicated ), where this is one form of formula expression, and it does not exclude other writing methods through formula transformation.

[0169] 3) The power P of a target first transmission on a second PRB k,common is P′ common .

[0170] 4) The power P of the target first transmission on a first PRB dedicated is Z11 P k,dedicated , where Z11 is the number of target first transmissions on the first PRB.

[0171] 5) The power P of the target first transmission on a second PRB common is P′ common .

[0172] 6) The power P of a target first transmission k is K3 times P k,dedicated The power is the sum of the power of Z10 times P k,common where K3 is the number of first PRBs occupied by a target first transmission.
