In addition, data can be transmitted directly between terminals at the physical layer, i.e., sidelink (or translated as secondary link, side link, side link, etc.) transmission. Among them, LTE sidelink communicates based on broadcast, which can be used to support basic safety communications of vehicle to everything (V2X), but is not suitable for other more advanced V2X services.

The method 200 may be, but is not limited to, executed by a terminal, and may be specifically executed by hardware or software installed in the terminal. In this embodiment, the method 200 may at least include the following steps.

[0027] S210: The terminal determines a power or quantity of a second transmission based on the first set.

[0028] Among them, the first set includes at least one first transmission, such as the first transmission can be but not limited to physical sidelink shared channel (Physical SideLink Shared Channel, PSSCH), physical sidelink control channel (Physical SideLink Control Channel, PSCCH), PSFCH, SL-positioning reference signal (PositioningReference 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 (Phase-tracking reference signal, PTRS, etc.), uplink transmission, downlink transmission, etc.

[0029] Of course, the first transmission may be a first transmission scheduled by the terminal, a first transmission expected by the terminal, or a transmission scheduled by the terminal, or may be a transmission selected by the terminal from one or more scheduled or expected or scheduled transmissions according to the terminal capability / limitation.

In this embodiment, the second PRB is used to carry target information, the first interlace is not used to carry target information, and the target information may include but is not limited to hybrid automatic repeat request acknowledgement (HARQ-ACK) information, conflict information, data information, control information, etc.

[0032] The first power is the power of a first PRB occupied by the second transmission, and the first PRB includes at least one of a second PRB, a third PRB, and a PRB occupied by the first interlace. The third PRB is not used to carry the target information, but can be used as a placeholder for transmission, to occupy a channel, or to meet Occupied Channel Bandwidth (OCB) requirements.

[0037] S310: The terminal determines a power or quantity of a second transmission based on the first set.

[0038] The first set includes at least one first transmission.

[0039] It can be understood that the implementation process of S310 can refer to the relevant description in the method embodiment 200. Of course, in addition to referring to the relevant description in the method embodiment 200, please refer to Figure 3 In some embodiments, the process of the terminal determining the power or quantity of the second transmission based on the first set may include the following S311 and S312.

[0040] S311, the terminal obtains first information.

[0041] There are many ways to obtain the first information, which are not limited here.

[0042] S312: Determine the power or quantity of the second transmission according to the first information and the first set.

[0043] The first information includes at least one of a reference power of the first transmission and a priority of the first transmission. In this regard, the following describes the process of determining the power or quantity of the second transmission based on the reference power of the first transmission and the priority of the first transmission in combination with two implementation methods, as follows.

[0044] Implementation 1: Reference power of the first transmission

[0045] In some embodiments, the reference power of the first transmission may include at least one of the following 101)-110).

[0046] 101) A reference power corresponding to a first PRB occupied by the first transmission, where the first PRB includes at least one of a second PRB, a third PRB, and a PRB occupied by a first interlace.

[0047] In this embodiment, the reference power P4=P5+10log 10 (2 u )+α·PL[dBm], where P5 is related to the basic operating point of the transmission power based on the (downlink) path loss power control. For example, if the terminal supports the use of parameter dl-P0-PSFCH-r17 and it is provided, then P5 is the value of dl-P0-PSFCH-r17, otherwise, P5 is the value of dl-P0-PSFCH-r16. α is related to the (downlink) path loss compensation factor. For example, α is the value of dl-Alpha-PSFCH and is provided, otherwise, α is 1; PL is related to the path loss of the first transmission. μ is related to the subcarrier spacing. For example, when the subcarrier spacing is 30KHz, μ is 1, when the subcarrier spacing is 60KHz, μ is 2, and so on.

[0048] 102) A reference power corresponding to a second PRB occupied by the first transmission.

[0049] For example, in this embodiment, the reference power P4=P5+10log 10 (2 u )+α·PL[dBm], where PL is related to the path loss of the first transmission. μ is related to the subcarrier spacing, for example, when the subcarrier spacing is 30 KHz, μ is 1, when the subcarrier spacing is 60 KHz, μ is 2, and so on.

[0050] 103) A reference power corresponding to a third PRB occupied by the first transmission or a PRB of the first interlace.

[0051] In this embodiment, the reference power corresponding to a third PRB occupied by the first transmission or a PRB of the first interlace is equal to the reference power corresponding to a second PRB occupied by the first transmission described in 102).

[0052] Alternatively, a reference power corresponding to a third PRB occupied by the first transmission or a PRB of the first interlace is determined according to the difference between a reference power corresponding to a second PRB occupied by the first transmission described in 102) and a first bias, and the value of the first bias is implemented by protocol predefinition, network configuration, terminal preconfiguration, etc., or the first bias is 0 or does not exist.

[0053] 104) A reference power corresponding to a second PRB occupied by the first transmission.

[0054] Wherein, the reference power P4=P5+10log 10 (K3)+α·PL[dBm], K3 is the first value, that is, the number of second PRBs occupied by one first transmission, such as 1, 2, 5, etc. In this embodiment, K3 may be determined by protocol pre-definition, network side configuration, etc.

[0055] 105) A reference power corresponding to a third PRB or a first interlace occupied by the first transmission.

[0056] In this embodiment, a reference power P6 corresponding to a third PRB or a first interlace occupied by the first transmission is equal to the reference power P4 in 103), or a reference power P6 corresponding to a third PRB or a first interlace occupied by the first transmission is the sum of Ncommon P7s, where P7 is the difference between the power obtained by evenly dividing the reference power P4 in 103) to a first value number of PRBs and the first offset, and Ncommon is the number of third PRBs occupied by the first transmission or the number of PRBs occupied by the first interlace.

[0057] For example, the reference power P6 corresponding to a third PRB occupied by the first transmission or a PRB of the first interlace is P4-10log 10 (K3)-P offset +10log 10 (N common ), P offset is the first bias.

[0058] 106) A reference power corresponding to the first transmission.

[0059] For example, the reference power corresponding to the first transmission is P4=P5+10log 10 (2 u ·M)+α·PL[dBm], the fourth value M is the number of PRBs or reference PRBs or third PRBs occupied by the target transmission, and the reference PRBs or third PRBs can be determined by protocol pre-definition, network configuration or terminal pre-configuration.

[0060] Based on this, in some embodiments, the reference power P6 corresponding to the third PRB occupied by the first transmission or the first interlace may be equal to the reference power P4 corresponding to the first transmission, or P6 is the difference between P4 and the first bias, or P6 is the sum of Ncommon P7s, where P4 is evenly divided into a fourth value M PRBs to obtain the difference between the power and the first bias, and Ncommon is the number of third PRBs occupied by the first transmission or the number of PRBs occupied by the first interlace.

[0061] For example, the reference power P6 corresponding to a third PRB occupied by the first transmission or a PRB of the first interlace is P4-10log 10 (M)-P offset +10log 10 (N common ), P offset is the first bias.

[0062] 107) a smaller value of a first reference power and a reference power corresponding to a first PRB occupied by the first transmission, wherein the first reference power is the maximum transmit power of each PRB that meets the PSD constraint.

[0063] Compared with 101), 107) considers the maximum transmission power of each PRB (i.e., the first reference power P PSD ) satisfies the PSD limit, thereby ensuring that the transmit power of each PSFCH transmission always satisfies P PSD restrictions.

[0064] 108) A smaller value between a first reference power and a reference power corresponding to a second PRB occupied by the first transmission.

[0065] Compared with 102), 108) also considers the maximum transmit power of each PRB (i.e., the first reference power P PSD ) satisfies the PSD limit, thereby ensuring that the transmit power of each PSFCH transmission always satisfies P PSD restrictions.

[0066] Based on this, in one implementation, the reference power corresponding to a third PRB or a first interlace occupied by the first transmission can be the smaller value described in 108), or the difference between the smaller value described in 108) and the first offset, thereby ensuring that the transmission power of each PSFCH transmission, etc. always satisfies P PSD restrictions.

[0067] 109) a smaller value of a second reference power and a reference power corresponding to a second PRB occupied by the first transmission, wherein the second reference power is the sum of a first value and the first reference powers, and the first value is the number of second PRBs occupied by the first transmission.

[0068] Compared with 104), 109) also considers the maximum transmit power of each PRB (i.e., the first reference power P PSD ) satisfies the PSD limit, thereby ensuring that the transmit power of each PSFCH transmission, etc., always satisfies P PSD restrictions.

[0069] Based on this, in one implementation, the reference power corresponding to a third PRB or a first interlace occupied by the first transmission can be the smaller value described in 109), or the difference between the smaller value described in 109 and the first offset, thereby ensuring that the transmission power of each PSFCH transmission, etc. always satisfies P PSD restrictions.

[0070] 110) a smaller value of a third reference power and a reference power corresponding to the first transmission, wherein the third reference power is the sum of a second value and the second reference power, and the second value is the number of PRBs or reference PRBs occupied by the first transmission.

[0071] Compared with 106), 110) also considers the maximum transmission power of each PRB (i.e., the first reference power P PSD ) satisfies the PSD limit, thereby ensuring that the transmit power of each PSFCH transmission, etc., always satisfies P PSD restrictions.

[0072] Based on this, in one implementation, the reference power corresponding to a third PRB or a first interlace occupied by the first transmission can be the smaller value described in 110), or the difference between the smaller value described in 110) and the first offset, thereby ensuring that the transmission power of each PSFCH transmission, etc. always satisfies P PSD restrictions.

[0073] It is worth noting that the terminal determines the power and quantity of the second transmission based on the reference powers in the aforementioned 101)-110), which can be achieved by protocol agreement, high-level configuration or terminal pre-configuration, and is not limited here.

[0074] Based on this, in some embodiments, if the first information includes a reference power of the first transmission, then the number of the second transmissions determined by the terminal based on the reference power of the first transmission may include at least one of the following 21)-23), so that the number of the second transmissions matches the terminal capabilities, etc., to ensure communication quality.

[0075] 21) The number of the second transmissions is the same as the number of the first transmissions included in the first set.

[0076] That is, all first transmissions in the first set may be determined to be the second transmissions.

[0077] 22) The number of the second transmissions is not less than a first threshold, wherein the first threshold is related to the first target power, such as the power of the first threshold number of second transmissions does not exceed the first target power or does not exceed the maximum value of the first target power.

[0078] The first target power may be any one of the following a)-c).

[0079] a) The maximum transmit power allowed by the terminal. The maximum transmit power allowed by the terminal may be the maximum transmit power of a second transmission allowed by the terminal, or may be the maximum transmit power of a PRB allowed by the terminal.

[0080] b) The maximum transmit power allowed by the terminal under PSD limitation, wherein the maximum transmit power allowed by the terminal may be the maximum transmit power of a second transmission allowed by the terminal, or the maximum transmit power of a PRB allowed by the terminal.

[0081] Optionally, the maximum transmit power allowed by the terminal based on the PSD limitation is determined according to at least one of the following b1)-b3).

[0082] b1) PSD limit information, that is, the maximum transmit power per L unit (e.g., MHz) width does not exceed S, such as P PSD =11dBm / MHz (L=1, S=11).

[0083] b2) frequency domain resources occupied by the first transmission, such as the PRB, interlace, second PRB, third PRB or PRB of the first interlace occupied by the first transmission.

[0084] b3) frequency domain resources occupied by the second transmission, such as the PRB, interlace, second PRB, third PRB or PRB of the first interlace occupied by the second transmission.

[0085] c) the minimum value between the maximum transmit power allowed by the terminal and the maximum transmit power allowed by the terminal based on the PSD limitation. The maximum transmit power allowed by the terminal may be the maximum transmit power of a second transmission allowed by the terminal, or the maximum transmit power of a PRB allowed by the terminal.

[0086] 23) The number of the second transmissions is determined according to the priority of the first transmission. For example, a predetermined number of second transmissions is selected from the first set according to the descending or ascending order of the priority of the first transmission, and the predetermined number may be the aforementioned first threshold or not less than the aforementioned first threshold, which is not limited here.

[0087] In some embodiments, after determining the number of the second transmissions, the terminal ensures that the power of the second transmission does not exceed the capability of the terminal, thereby ensuring the communication quality. Therefore, in this embodiment, the power of the second transmission is also specified, and the power of the second transmission is described from the perspectives of the first power, the second power, and the third power.

[0088] The first power of the second transmission includes at least one of the following 31)-34).

[0089] 31) The first power is a reference power for the first transmission.

[0090] 32) The first power is the smaller value between the first transmitted reference power and the fourth reference power.

[0091] The fourth reference power is determined based on at least one of the first target power, the number of the second transmissions, a first value, and a third value, the third value is related to at least one of the type of the second transmission, the structure of the second transmission, the number of third PRB groups occupied by the second transmission, the number of first interlaces occupied by the second transmission, and the number of resource block sets RB sets occupied by the second transmission, and the first value is the number of second PRBs occupied by the first transmission.

[0092] It is also worth noting that the type of the second transmission or the structure of the second transmission mentioned in the context of this application can be that each transmission occupies 1 first interlace (10 PRBs), each transmission occupies 1 first intelace and a first value of second PRBs, etc., and there is no limitation here.

[0093] For example, assuming that the first target power is the maximum transmit power P allowed by the terminal cmax , then the fourth reference power can be P cmax -10log 10 (N1·K3+z3), K3 is the first value, and z3 is the third value. Wherein, when the third value is the number of groups of the third PRB occupied by the second transmission or the number of the first interlace occupied by the second transmission, z3 is 1, or one RB set has one first interlace, and z3 is the number of RB sets, which can also be understood as counting one third PRB or the PRB occupied by the first interlace as one PRB of the second transmission.

[0094] Correspondingly, the first power may be P4=min((P cmax -10log 10 (N1·K3+z3), P c ), P c is the reference power of the first transmission.

[0095] It is worth noting that the reference power of the first transmission can refer to the above-mentioned 101)-110), which will not be repeated here.

[0096] 33) The first power is the power obtained by evenly dividing the reference power of the first transmission to a fourth value number of PRBs, and the fourth value is the number of PRBs or reference PRBs occupied by the first transmission.

[0097] For example, the first power may be P c -10log 10 (M), M is the fourth value.

[0098] It is worth noting that the reference power of the first transmission can refer to the above-mentioned 101)-110), which will not be repeated here.

[0100] The fifth reference power is determined according to at least one of the first target power, the number of the second transmissions, and the third value. For example, the fifth reference power may be P cmax -10log 10 (N1+z3)-10log(K3), z3 is the third value, N1 is the number of the second transmissions, and K3 is the first value, that is, the number of second PRBs occupied by one first transmission.

[0101] The sixth reference power is related to at least one of the reference power of the first transmission and the first value K3. For example, the sixth reference power is P c -10log(K3).

[0103] The second power of the second transmission includes at least one of the following 41)-49).

[0104] 41) The second power is a reference power for the first transmission.

[0105] It is worth noting that the reference power of the first transmission can refer to the above-mentioned 101)-110), which will not be repeated here.

[0106] 42) The second power is the smaller value between the reference power of the first transmission and the seventh reference power.

[0108] For example, the seventh reference power may be P cmax -10log 10 (N1×K3+Ncommon), correspondingly, the second power is min{(P cmax -10log 10 (N1×K3+Ncommon),Pc)}, wherein Ncommon is the number of third PRBs occupied by the first transmission in the first set or the number of PRBs occupied by the first interlace of the first transmission in the first set, Pc is the reference power of the first transmission, Pcmax is the first target power, and K3 is the first value, i.e., the number of second PRBs occupied by one first transmission.

[0109] It is worth noting that the reference power of the first transmission can refer to the above-mentioned 101)-110), which will not be repeated here.

[0110] 43) The second power is a smaller value between the reference power of the first transmission and the eighth reference power.

[0111] The eighth reference power is determined according to at least one of the first target power, the number of the second transmissions, the first value, and the third value.
