[0103] 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), 6th generation mobile communication system (6G), 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 (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based thereon, and the like. Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0104] A power headroom report (PHR) is reported by a terminal to a network device (e.g., a base station) to determine the power headroom (PH) of the terminal. The PHR indicates the PH value, and the network device can determine how much power headroom the terminal has for transmitting a signal or a channel according to the PHR, so that the network device can better control and schedule the transmission power of the terminal when the terminal transmits a signal or a channel at the next transmission occasion, to ensure effective use of network resources and communication quality.

[0105] In some embodiments, the formula for determining the power headroom is PH = Pcmax - Pactual, where Pcmax is the maximum transmission power of the terminal, and Pactual is the actual transmission power determined according to the power control formula of the uplink channel and signal specified by the protocol.

[0106] For example, if the PH value in the PHR is greater than 0 and is 5 dBm, the network device knows that the terminal has 5 dBm of power headroom for transmitting a signal. Therefore, the network device can instruct the terminal to increase its transmission power when transmitting a signal or a channel at the next transmission occasion. For example, the network device can indicate the power value that the terminal can increase when transmitting a signal or a channel by transmitting a transmit power control (TPC) value, or the network device can increase the transmission power by indicating the number of resources occupied by the signal or the channel.

[0107] In NR, three types of PHR are specified, and the specific information is as follows:

[0108] Type 1: the difference between the nominal maximum transmission power of the terminal for each activated serving cell and the actual transmission power of the uplink shared channel (UL-SCH) (i.e., the actual transmission power determined according to the power control formula of the uplink channel and signal specified by the protocol);

[0109] Type2: the difference between the terminal nominal maximum transmit power and the actual power of the UL-SCH and the physical uplink control channel (PUCCH) sent on a special cell (SpCell) of another medium access control (MAC entity) (only the evolved universal terrestrial radio access (E-UTRA) MAC entity in the case of E-UTRA to NR dual connectivity (EN-DC));

[0110] Type3: the difference between the terminal nominal maximum transmit power of each activated serving cell and the actual power of the sounding reference signal (SRS) sent.

[0111] The maximum transmit power of the terminal refers to the maximum transmit power value that can be used when the amplifier of the terminal works in the linear region. However, the maximum transmit power of the terminal can be adjusted by artificial intelligence (AI), for example, before adjustment, the maximum transmit power value of the terminal is Pcmax2, after AI adjustment, according to the type of the transmitted signal, the state of the channel and other information, and through an algorithm and other ways, the maximum transmit power value of the terminal is adjusted to Pcmax1. The Pcmax1 value adjusted by AI can be dynamically changed, and when Pcmax1 is used as the maximum transmit power value, the power amplifier of the terminal still works in the linear region.

[0112] After AI adjustment, the maximum transmit power Pcmax value of the terminal changes, and a certain scheme is needed for the reporting of the power headroom.

[0113] Therefore, the embodiment of the present disclosure provides a communication method, in response to adjusting the maximum transmit power of the terminal, the terminal sends first information to the network device, the first information is used to determine the first power headroom of the terminal, and the network device can determine the adjusted power headroom of the terminal according to the first information, thereby improving the communication efficiency.

[0238] Figure 4 This is a flowchart illustrating a communication method according to an embodiment of this disclosure. Figure 4 As shown, this disclosure relates to a communication method executed by network device 102, the method including:

[0239] Step S4101: Obtain the first information.

[0240] For optional implementations of step S4101, please refer to [link / reference]. Figure 2A Step S2101 Figure 2B Optional implementation methods of step S2201, and Figure 2A , Figure 2B Other related parts in the embodiments involved will not be described in detail here.

[0241] In some embodiments, network device 102 receives first information sent by terminal 101, but is not limited thereto; it may also receive first information from other entities.

[0242] Step S4102: Determine the first power margin of the terminal.

[0243] For optional implementations of step S4102, please refer to [link / reference]. Figure 2B Optional implementation methods of step S2202, and Figure 2A Other related parts in the embodiments involved will not be described in detail here.

[0244] In some embodiments, network device 102 determines a first power margin for the terminal.

[0245] The communication method involved in the embodiments of this disclosure may include at least one of steps S4101 to S4102. For example, step S4101 may be implemented as a standalone embodiment, but is not limited thereto.

[0246] In some embodiments, step S4102 is optional, and one or more of the steps can be omitted or replaced in different embodiments.

[0247] In some embodiments, the above method can include the method of the above-mentioned embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0248] The communication method according to the embodiments of the present disclosure can include any of the following manners.

[0249] Manner one: when Pcmax changes, the UE determines PHR according to the newly determined Pcmax1 value, and the UE needs to report the offset value offset of Pcmax1 relative to the original Pcmax2 and / or the PHR determined using Pcmax2 to the network device (such as a base station).

[0250] The PH value calculated using Pcmax2 is: PH = Pcmax2 - P actual , P actual is the actual transmission power specified according to the existing regulation of the uplink channel and signal power control formula. Wherein, Pcmax2 is the maximum transmission power value of the UE before AI adjustment, and Pcmax1 is the maximum transmission power value of the UE after AI adjustment.

[0251] For example, the actual transmission power of the SRS signal determined according to the protocol specified power control formula is: P CMAX,f,c (i) = Pcmax2.

[0252]

[0253] The offset value offset can be reported to the base station alone or together with the PHR.

[0254] The offset value offset is carried in the MAC CE, or the offset value offset is carried in the physical layer control signaling, such as the offset value of the maximum power reported in the PUCCH.

[0255] The indication method of the offset value offset is: manner 1: define the mapping table of the offset value index and the offset value, and use M bits to indicate the index corresponding to the offset value; manner 2: directly indicate the offset value.

[0256] The maximum value of the offset value offset max is defined as offset max .

[0257] The reporting of the offset value is applicable to type 1 PHR reporting, type 3 PHR reporting, or a new type X PHR reporting. The new type X PHR reporting refers to PHR reporting for a newly introduced uplink signal or channel. For example, type X is newly introduced PHR reporting for sensing RS.

[0258] For example, for type 1 PHR reporting, the maximum transmission power of the UE is 20 dBm, and after AI adjustment, the maximum transmission power of the UE can reach 23 dBm. The offset value of the maximum power is 3 dBm. The UE indicates the offset value to the network device.

[0259] For example, the range of the offset value of the AI-adjusted Pcmax 2 relative to the original Pcmax 1 is defined as [x1, x2], and the corresponding index is determined based on the value range. The step is 1 dBm, and there are M values between [x1, x2]. Therefore, log2(M) bits are used to indicate the offset value. As shown in Table 1, a mapping table of index and offset value is defined, and the offset value is indicated by indicating the index.

[0260] Method 2: When Pcmax changes, the UE determines PHR according to the newly determined Pcmax 1, and reports the determined PHR and the offset value of Pcmax 1 relative to the original Pcmax 2 to the base station.

[0261] Pcmax 2 is the maximum transmission power value of the UE without AI adjustment, and Pcmax 1 is the maximum transmission power value of the UE after AI adjustment.

[0262] For example, the PH value is indicated in PHR, and the PH value calculated using Pcmax 1 is: PHR = Pcmax 2 - Pactual, Pactual is the actual transmission power specified by the power control formula of the existing protocol for uplink channels and signals. (Example same as method 1)

[0263] The PH value is also carried in the MAC CE.

[0264] The newly determined Pcmax 1 is the maximum transmission power value after AI adjustment. It is defined that the maximum Pcmax 1 is less than or equal to P.

[0265] The AI-adjusted PHR reporting method is applicable to type 1 PHR reporting, type 3 PHR reporting, or a new type X PHR reporting. The new type X PHR reporting refers to PHR reporting for a newly introduced uplink signal or channel. For example, type X is newly introduced PHR reporting for sensing RS.

[0266] For example, Table 2 defines a mapping table of index and PH value, by indicating the index, the network device is indicated the PH value, the range of the PH value is [x3, x4], and the corresponding index is determined based on the value range, the step is 1dBm, there are N values between [x3, x4], then log2(N) bits are used to indicate the offset value.

[0267] Method 3: The network device (such as a base station) calculates the PH value of the UE sending an uplink signal or channel based on the information reported by the UE.

[0268] Embodiment 1: When Pcmax changes, the UE reports the actual transmission power Pactual determined according to the power control formula of the uplink channel and signal specified in the existing protocol, and the maximum transmission power Pcmax1 after AI adjustment to the base station, and the base station calculates the PH value of the UE sending an uplink signal or channel according to the Pcmax1 and Pactual values. In this way, the UE does not need to calculate and report the PH value to the network device.

[0269] After the UE accesses the network, the UE reports the maximum transmission power Pcmax1, which has the following two methods, method 1: the UE can directly report the maximum transmission power Pcmax1 after AI adjustment in the UE capability report; method 2: the UE reports the offset value of the maximum power in the UE capability report, which is the offset value between the maximum transmission power Pcmax1 after AI adjustment and the maximum transmission power Pcmax2 before AI adjustment.

[0270] The base station calculates the PH value as follows: PH value = Pcmax1 - Pactual (corresponding to the above method 1, the UE directly reports Pcmax1 in the UE capability report), or the base station calculates the PH value as follows: PH value = Pcmax2 + offset - Pactual (corresponding to the above method 2, the UE reports the offset value of the maximum power in the UE capability report).

[0271] In the UE capability report, the power level is reported, and the maximum transmission power value of the signal or channel is determined according to the power level.

[0272] The actual transmission power Pactual of the signal or channel can be carried in the MAC CE or the physical layer control signaling to indicate the base station, which can directly indicate the actual transmission power value Pactual, or the protocol defines a mapping table of index and the corresponding actual transmission power value, and the UE indicates the actual transmission power value Pactual by indicating the index to the network device.

[0273] For example, the actual transmission power decided by the UE is in the range of [P1, P2], the indicated step is 1dBm, there are K values between [P1, P2], then log2(K) bits are used to indicate the index of the power, and the base station determines the actual transmission power value of the uplink channel or signal according to the index.

[0274] Embodiment 2: When Pcmax changes, the UE reports the actual transmission power Pactual determined according to the power control formula of the uplink channel and signal specified in the existing protocol and the offset value offset to the base station, and the base station calculates the PH value of the UE transmitting the uplink signal or channel according to Pactual and offset and Pcmax2.

[0275] For Pcmax2, the UE reports Pcmax2 in the UE capability report after accessing the network.

[0276] The offset value offset is the offset value of the maximum transmission power Pcmax1 after AI adjustment relative to the maximum transmission power value Pcmax2 of the UE before AI adjustment.

[0277] The base station calculates the PH value according to the following formula according to Pcmax2, Pactual and offset.

[0278] The base station calculates PH according to the following formula according to Pactual and offset and Pcmax2.

[0279] The above PHR reporting is applicable to the uplink channels or signals such as PUCCH, PUSCH, SRS, sensing RS, etc., and the protocol is as follows:

[0297] The power formula of SRS can be:

[0298]

[0299] wherein P CMAX,f,c (i) is the maximum transmission power value of the UE;

[0300] P O_SRS,b,f,c (q s ) is the target power value determined according to the SRS resource set q s ;

[0301] 10log 10 (2 μ ·M SRS,b,f,c(i)) is a normalized power value on the frequency domain resource occupied by the SRS;

[0305] P CMAX,f,c (i) represents a linear value of P

[0306] The power formula of the PRACH (Physical Random Access Channel) is: P PRACH,b,f,c (i) = min{P CMAX,f,c (i), P PRACH,target,f,c + PL b,f,c}

[0307] Wherein, P PRACH,target,f,c is a target received power value;

[0308] PL b,f,c is a road loss value between the UE and the base station determined by the UE according to the reference signal measurement.
