The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0104] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0105] In the sidelink unlicensed frequency band, one physical sidelink control channel (PSFCH) is supported for transmission on one common interlace and K3 dedicated frequency resource blocks (PRBs). Different transmit powers are considered for the PSFCH on the dedicated PRB and the common interlace PRB, and the transmit power of the PSFCH on the common interlace is lower than the transmit power on the K3 dedicated PRBs.

[0106] In some embodiments, subject to the maximum transmit power Pcmax, the terminal can determine the number of PSFCHs to be simultaneously transmitted on a single PSFCH occasion. That is, if the total transmit power of the scheduled PSFCHs is less than or equal to Pcmax, all scheduled PSFCHs can be transmitted, provided that the maximum number of PSFCHs that the terminal can transmit is not exceeded. If the total transmit power of the scheduled PSFCHs is greater than Pcmax, the PSFCHs to be transmitted and the number of PSFCHs to be transmitted are determined in ascending order based on the priority value of each PSFCH.

[0107] However, when the PSFCHs on the dedicated PRB and the common interlace use different transmit powers, how to determine the number of PSFCHs to be transmitted simultaneously in one PSFCH occasion?

[0108] Based on this, an embodiment of the present disclosure provides a communication method. When a terminal uses different transmission powers to send PSFCH on a dedicated PRB and a common interlace, the terminal determines the number of PSFCHs sent simultaneously in one PSFCH occasion to perform power control, thereby reducing the interference of the sidelink on other signals.

[0183] In some embodiments, the name of N is not limited, and it can be, for example, "N Tx,PSFCH ”.

[0190] In some embodiments, when providing the high-level parameter dl-P0PSFCH, the relationship between the total number of PSFCHs scheduled by the terminal and the first number, and the relationship between the total transmit power of the PSFCHs scheduled by the terminal and the maximum transmit power can be divided into the following four situations, as follows.

[0191] Case 1, N sch，Tx，PSFCH ≤N max，PSFCH , and satisfies P PSFCH,one +10log 10 (N sch，Tx，PSFCH )≤P CMAX , then N Tx,PSFCH =N sch，Tx，PSFCH .

[0196] That is, the number of PSFCHs scheduled by the terminal is greater than the maximum number of PSFCHs that the terminal's capability supports, and the total transmit power of the PSFCHs scheduled by the terminal is greater than the maximum transmit power, then the terminal determines the number N of PSFCHs to be sent simultaneously on one PSFCH occasion in ascending order based on the priority values ​​of the PSFCHs scheduled by the terminal.

[0197] Optionally, the total transmit power of N PSFCHs satisfies the following relationship: That is, the total transmit power of N PSFCHs is less than or equal to the maximum transmit power.

[0198] Optionally, the transmit power of each PSFCH satisfies the following relationship: P PSFCH,k(i) =min(P CMAX -10log 10 (N Tx,PSFCH ),P PSFCH,one ).

[0203] That is, the number of PSFCHs scheduled by the terminal is less than or equal to the maximum number of PSFCHs supported by the terminal's capabilities, and the total transmit power of the PSFCHs supported by the terminal's capabilities is greater than the maximum transmit power.

[0208] In mode 1-2, the first information does not configure the first configured power, that is, the network device does not configure the higher-layer parameter d1-P0-PSFCH.

[0209] In some embodiments, the number N of PSFCHs simultaneously transmitted on one PSFCH occasion depends on the terminal implementation.

[0210] In some embodiments, the total transmit power of the N PSFCHs is less than or equal to the maximum transmit power.

[0214] Method 2: The terminal determines the number of PSFCH PRBs sent on the common interlace and the number of PSFCH PRBs sent on the dedicated PRB respectively. The sum of the two is the total number A of PSFCH PRBs sent simultaneously by the terminal on one PSFCH occasion, and the total transmit power on these A PSFCH PRBs is less than or equal to the maximum transmit power.

[0215] In some embodiments, the number of PSFCH PRBs sent on the common interlace is 10 PRBs or 11 PRBs.
