The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0221] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0222] 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 determination methods, and next-generation systems based on and extending these systems. Furthermore, a combination of multiple systems (e.g., a combination of LTE or LTE-A with 5G) may also be employed.

[0223] Optionally, in a communication system, PSFCH transmission opportunities typically have a maximum transmit power limit, i.e., the sum of the transmit powers of all PSFCHs in a PSFCH transmission opportunity is less than or equal to the maximum transmit power Pcmax. When the transmit power of each PSFCH in a PSFCH transmission opportunity is large, or a large number of PSFCHs are transmitted in a PSFCH transmission opportunity, the sum of the transmit powers of all PSFCHs in the PSFCH transmission opportunity may exceed the maximum transmit power. In this case, power control of the PSFCH is required. Specifically, the transmit power of each PSFCH in a PSFCH transmission opportunity, the number of PSFCHs transmitted in a PSFCH transmission opportunity, and the transmit power of each PSFCH on each common PRB and each dedicated PRB need to be determined, so that the transmit power of all PSFCHs in a PSFCH transmission opportunity does not exceed the maximum transmit power. However, how to perform power control on the PSFCH is a technical problem that urgently needs to be solved.

[0224] In addition, optionally, in a communication system, in order to improve the coverage of information on dedicated PRBs, the transmission power of PSFCH on dedicated PRBs in PSFCH transmission opportunities is usually made higher than the transmission power of PSFCH on public PRBs, and the higher value is 1 pre-configured offset value. However, at present, when the sum of the transmission powers of all PSFCHs in the PSFCH transmission opportunity is greater than the maximum transmission power, "how to perform power control to ensure that the sum of the transmission powers of all PSFCHs in the PSFCH transmission opportunity is not greater than the maximum transmission power, while also making the transmission power of PSFCH on dedicated PRBs higher than the transmission power of PSFCH on public PRBs" is also a technical problem that needs to be solved urgently.

[0225] Figure 2 is an interactive diagram of a determination method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiment of the present disclosure relates to a determination method, which is executed by a terminal, and the method includes:

[0226] Step 2101: If the sum of the transmit powers corresponding to all first channels on a first transmission opportunity is greater than the maximum transmit power corresponding to the first transmission opportunity, determine a preconfigured first offset value.

[0227] Optionally, the first transmission opportunity can be understood as the transmission resource of the first channel, for example. Optionally, the first transmission opportunity can include a first type of frequency domain resources and a second type of frequency domain resources. Optionally, the first type of frequency domain resources can be public frequency domain resources, for example, common interlace resources, and the second type of frequency domain resources can be dedicated frequency domain resources.

When the sum of the transmit powers corresponding to all first channels on the first transmission opportunity is greater than the maximum transmit power corresponding to the first transmission opportunity, it is necessary to perform power control on the first channel so that the controlled transmit power of the first channel does not cause the sum of the transmit powers corresponding to all first channels on the first transmission opportunity to be greater than the maximum transmit power. The maximum transmit power can be pre-configured or agreed upon by a protocol. For example, the maximum transmit power can be between [-33, 30] dBm (decibel milliwatts).

[0405] For further detailed description of step 5201, please refer to the above embodiment description.

[0406] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0407] The following is an exemplary introduction to the above method.

[0408] Optionally, the present disclosure proposes a method for performing power control on the PSFCH when all PSFCH transmissions on one PSFCH occasion exceed the maximum transmission power value PCMAX.

[0409] Optionally: When all PSFCH transmissions on one PSFCH occasion exceed the maximum transmission power value PCMAX, and the number of PSFCHs to be transmitted N is determined Tx,PSFCH , 1 PSFCH transmission occupies 1 common interlace and K3 dedicated PRBs, and 1 common interlace contains M PRBs (M = 10 or 11), and the pre-configured offset value is offset

[0410] Optional embodiment 1: (using formula 1) divide PCMAX evenly into N Tx,PSFCH Ppsfch,one' (dBm) is obtained by subtracting (K3×offset) from Ppsfch,one' (using Formula 2) to obtain the power value P (dBm). P is then evenly divided into N' PRBs (using Formula 3) to obtain the power value P1. At this time, for a PSFCH transmission, the power value P_common on each common PRB is P1. The power value P_dedicated on each dedicated PRB is calculated (using Formula 4) by adding a preconfigured offset value to P1 (Note: In this scheme, after exceeding PCMAX, it is still guaranteed that the power value of a dedicated PRB is higher than that of the common PRB by offset dBm). (The following formula and this power control process are hereby protected) Ppsfch,one'=P CMAX -10log 10 (N Tx,PSFCH )dBm Formula 1 P=10log 10 (10(Ppsfch,one'÷10)-10(k3×offset÷10))dBm Formula 2 P_common=P–10log(N')dBm Formula 3 P_dedicated=10log 10 (10(P_common÷10)+10(offset÷10))dBm Formula 4

[0411] Optional embodiment 2: (using formula 1) divide PCMAX evenly on each PSFCH to obtain the total power Ppsfch,one' sent on one PSFCH, (using formula 2) divide Ppsfch,one' equally on N' PRBs to obtain the power value P1, and the power value on each dedicated PRB and common PRb is equal and equal to P1 (in this embodiment, after exceeding PCMAX, the power values ​​on dedicated PRB and common PRB are equal, that is, when exceeding PCMAX, there is no guarantee that the power values ​​on dedicated PRB and common PRB differ by offset Ppsfch,one'=P CMAX -10log 10 (N Tx,PSFCH )dBm Formula 1 P1=Ppsfch,one'-10log 10 (N')dBm Formula 2 P_dedicated=P_common=P1 dBm Formula 3

[0412] Optional embodiment three: The preconfigured offset value is scaled to offset', and the offset' value is the total power value Ppsfch,one' sent by one PSFCH, the maximum power value PCMAX sent on one PSFCH occasion, and the number of PSFCHs sent N Tx,PSFCH , the offset between the pre-configured dedicated PRB and the common PRB, and the power control is performed based on the determined offset' so that the power difference between one dedicated PRB and the common PRB is offset'

[0413] The offset' value is determined by the following formula: the pre-configured offset and offset' satisfy a certain proportional relationship, and the proportional value is equal to the ratio of Ppsfch,one to Ppsfch,one', where Ppsfch,one is calculated by formula 2 (indicating the total transmit power of one PSFCH when the maximum power PCMAX is not exceeded), and Ppsfch,one' is equal to PCMAX divided by N Tx,PSFCH (When the maximum power PCMAX is exceeded, the maximum power is divided equally into N Tx,PSFCH , get the total power of each PSFCH) P PSFCH,one =P O,PSFCH +10log 10 (2 μ ×N')+α PSFCH PL formula 2

[0414] Power control is performed using the determined offset', specifically in the following manner (the method is the same as in the second optional embodiment, but the pre-configured offset is replaced by offset'):

[0415] (Using formula 1) divide PCMAX evenly into N Tx,PSFCHPSFCH, the total power transmitted on one PSFCH is Ppsfch,one'(dBm). (Using Formula 2), subtract (k3×offset') from Ppsfch,one' to obtain the power value P(dBm). (Using Formula 3), P is evenly divided into N' PRBs to obtain the power value P1. At this time, for one PSFCH transmission, the power value on each common PRB is P1. (Using Formula 4), the power value on each dedicated PRB is P_dedicated dBm. (In this embodiment, after exceeding PCMAX, it is still guaranteed that the power value of the dedicated PRB is higher than that of the common PRB by offset'dBm.) Ppsfch,one'=P CMAX -10log 10 (N Tx,PSFCH )dBm Formula 1 P=10log 10 (10(Ppsfch,one'÷10)-10(k3×offset'÷10))dBm Formula 2 P_common=P1'=P–10log(N')dBm Formula 3 P_dedicated=10log 10 (10 (P1'÷10) +10(offset'÷10))Formula 4

[0416] Optional embodiment 4: Divide PCMAX evenly onto N_(Tx,PSFCH) PSFCHs to obtain the total power Ppsfch,one'(dBm) transmitted on one PSFCH. The power value on each dedicated PRB is still calculated according to the formula for calculating the power on one PRB in the legacy sidelink. Subtract the total power on K3 dedicated PRBs from the transmit power of one PSFCH to obtain the total power on one common interlace. The total power is evenly distributed on N common PRBs to obtain the power value on each common PRB.

[0417] Alternatively, (using Equation 1) divide PCMAX equally into N Tx,PSFCHPSFCH, the total power Ppsfch,one'(dBm) sent on one PSFCH is obtained. Ppsfch,one' is the sum of P1 and P2. P1 is the sum of the powers of M common PRBs, and P2 is the sum of the powers of K3 dedicated PRBs. The sum of the powers of K3 dedicated PRBs, P2, is calculated according to Formula 2. Then, P1 is further calculated using Formula 3. Then, P1 is evenly divided into M common PRBs, and the power value p_common on each common PRB is obtained (calculated using Formula 4). (This embodiment can ensure that the power of each dedicated PRB is higher than the power of each common PRB, but the higher value is the calculated offset "value) Ppsfch,one'=P CMAX -10log 10 (N Tx,PSFCH )dBm Formula 1 P2=P O,PSFCH +10log 10 (2 μ ×K3)+α PSFCH PL dBm Formula 2 P1=10log 10 (10(Ppsfch,one'÷10)-10 (P2÷10) )dBm Formula 3 P1=P _common +10log 10 (M)dBm Formula 4

[0418] In some embodiments, there are two ways to determine the value of N' in the above solution:

[0419] Optionally: the value of N' is equal to the sum of the higher-layer parameter numRefPRBOfInterlace and K3, where the higher-layer parameter numRefPRBOfInterlace refers to the number of reference PRBs in one interlace and is in the range of {10, 11}, and the value range of K3 is {1, 2, 5}.

[0420] Optionally: the value of N' is equal to the number of PRBs actually occupied by one PSFCH, which is equal to the sum of the number of PRBs contained in one common interlace (M PRBs) and K3 PRBs.
