[0092] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0093] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.

[0094] In some embodiments, terminal 101 may be, for example, a user equipment (UE), including at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home, but not limited thereto.

[0098] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0099] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0100] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0101] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0102] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary.

[0103] The embodiments disclosed herein 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), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a 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, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0104] A Power Headroom Report (PHR) is a report submitted by a terminal to network equipment (such as a base station) to determine the terminal's power headroom (PH). The PHR indicates the PH value. Based on the PHR, the network equipment can know how much power headroom the terminal has left, and thus better control and schedule the terminal's transmission power when the terminal transmits signals or channels at the next transmission opportunity, thereby ensuring the effective utilization of network resources and ensuring communication quality.

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

[0106] For example, if the pH value in the PHR is greater than 0 and is 5dBm, the network device knows that the terminal has a 5dBm margin in its transmission power. Therefore, when scheduling signals for the next transmission opportunity, the network device can instruct the terminal to increase its transmission power. For instance, the network device can instruct the terminal to increase its transmission power by using a Transmit Power Control (TPC) value, or by indicating the amount of resources occupied by the signal or channel.

[0107] The NR specifies three types of PHR, as detailed below:

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

[0109] Type 2: The difference between the terminal's nominal maximum transmit power and the actual power transmitted on the UL-SCH and Physical Uplink Control Channel (PUCCH) of a special cell (SpCell) of another Medium Access Control (MAC) entity (only for Evolved Universal Terrestrial Radio Access (E-UTRA) MAC entities in the case of UTRA-NR Dual Connectivity (EN-DC)). (This type of PHR reporting is not currently supported.)

[0110] Type 3: The difference between the nominal maximum transmit power of the terminal in each active serving cell and the actual transmit power of the Sounding Reference Signal (SRS).

[0111] The maximum transmit power of a terminal refers to the maximum transmit power value that the terminal's amplifier can use when operating in the linear region. However, Artificial Intelligence (AI) can adjust the terminal's maximum transmit power. For example, before adjustment, the terminal's maximum transmit power value is Pcmax2. After AI adjustment, based on information such as the type of transmitted signal and the channel state, and through algorithms, the terminal's maximum transmit power value is adjusted to Pcmax1. The Pcmax1 value adjusted by AI can be dynamically changed, and when using Pcmax1 as the maximum transmit power value, the terminal's power amplifier still operates in the linear region.

[0112] After AI adjustments, the terminal's maximum transmit power Pcmax value changed. A solution is needed to report the power margin.

[0113] In view of this, embodiments of the present disclosure provide a communication method in which, in response to adjusting the maximum transmission power of a terminal, the terminal sends first information to a network device. The first information is used to determine a first power margin of the terminal. The network device can determine the adjusted power margin of the terminal based on the first information, thereby improving communication efficiency.

[0153] In some embodiments, a mapping table of indexes and offsets can be defined, using M bits to indicate the index corresponding to the offset.

[0154] For example, the offset range of the first maximum transmit power Pcmax1 after AI adjustment relative to the second maximum transmit power Pcmax2 before adjustment is defined as [x1, x2]. Based on this range, a corresponding index is determined, with a step size of 1 dBm. There are M values ​​between [x1, x2], so log2M bits are used to indicate the offset value. As shown in Table 1, a mapping table between the index and the offset value is defined, and the offset value is indicated by the index.

Type X PHR reporting refers to PHR reporting for newly introduced uplink signals or channels. For example, type X is a newly introduced PHR reporting for sensing signals (sensing RS).

[0157] For example, for type 1 PHR reporting, the terminal's second maximum transmit power is 20dBm. After AI adjustment, the terminal's first maximum transmit power can reach 23dBm, so the offset value is 3dBm. The terminal reports this offset value to the network device.

The indicated step size is 1 dBm or determined according to the actual situation. There are N values ​​between [x3, x4], so log2N bits are used to indicate the offset value. As shown in Table 2, a mapping table between the third index and the first power margin, i.e., the reported value and the power margin value, is defined. The first power margin is indicated by indicating the reported value.

[0240] In some embodiments, network device 102 determines a first power margin for the terminal.

[0241] 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.

[0242] In some embodiments, step S4102 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0243] In some embodiments, the above methods may include the methods of the embodiments described above on the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0244] This disclosure provides a communication method that may include any of the following methods.

[0245] Method 1: When Pcmax changes, the UE determines the PHR according to the newly determined Pcmax1 value. The UE needs to report the offset value of Pcmax1 relative to the original Pcmax2, and / or the PHR determined using Pcmax2 to the network device (e.g., base station).

[0246] The pH value calculated using Pcmax2 is: pH = Pcmax2 - P actual P actual This refers to the actual transmit power specified according to the existing power control formula for the uplink channel and signal. Where Pcmax2 is the maximum transmit power value of the UE before AI adjustment, and Pcmax1 is the maximum transmit power value of the UE after AI adjustment.

[0247] For example, when transmitting an SRS signal, the actual transmission power determined according to the power control formula specified in the protocol is: P CMAX,f,c (i) = Pcmax2.

[0248] This offset value can be reported to the base station separately, or it can be reported to the base station together with the PHR.

[0249] The offset value is carried in the MAC CE or in the physical layer control signaling, such as reporting the offset value of the maximum power in the PUCCH.

[0250] Offset value indication methods: Method 1: Define a mapping table between offset values ​​and index values, using M bits to indicate the index corresponding to the offset value; Method 2: Directly indicate the offset value.

[0251] Define the maximum value of the offset. max The offset of maximum power must be less than or equal to offset. max .

[0252] The reporting of this offset value applies 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 newly introduced uplink signals or channels. For example, type X is a newly introduced PHR reporting for sensing RS.

[0253] For example, for type 1 PHR reporting, if the UE's maximum transmit power is 20dBm, after AI adjustment, the UE's maximum transmit power can reach 23dBm. The offset value of the maximum power is 3dBm, and the UE indicates this offset value to the network device.

[0254] For example, the range of offset values ​​between the AI-adjusted Pcmax 2 and the original Pcmax 1 is defined as [x1, x2]. Based on this range, the corresponding index is determined, with a step size of 1 dBm. There are M values ​​between [x1, x2], so log2(M) bits are used to indicate the offset value. Table 1 shows the mapping table defining the index and the offset value, where the offset value is indicated by the index.

[0255] Method 2: When Pcmax changes, the UE determines the PHR according to the newly determined Pcmax1, and the UE reports the determined PHR and the offset value of Pcmax1 relative to the original Pcmax2 to the base station.

[0256] Wherein, Pcmax2 is the maximum transmit power value of the UE before AI adjustment, and Pcmax1 is the maximum transmit power value of the UE after AI adjustment.

[0257] For example, the pH value indicated in PHR is calculated using Pcmax1 as follows: PHR = Pcmax 2 - Pactual, where Pactual is the actual transmit power specified by the power control formula for the uplink channel and signal according to existing protocols. (Example same as Method 1)

[0258] This pH value is also carried in MAC CE.

[0259] The newly determined Pcmax1 is the maximum transmission power value after AI adjustment, and the maximum Pcmax1 is defined to be less than or equal to P.

[0260] 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 newly introduced uplink signals or channels. For example, type X is a newly introduced PHR reporting for sensing RS.

[0261] For example, Table 2 defines a mapping table between index and PH value. By indicating the index, the PH value is indicated to the network device. The range of PH value is [x3, x4], and the corresponding index is determined based on this range. The step size of the indication is 1 dBm. There are N values ​​between [x3, x4], so log2(N) bits are used to indicate the offset value.

[0262] Method 3: The network device (e.g., base station) calculates the PH value of the uplink signal or channel transmitted by the UE based on the information reported by the UE.

[0263] Example 1: When Pcmax changes, the UE reports to the base station the actual transmit power Pactual, determined according to the power control formula for the uplink channel and signal as specified in the existing protocol, and the maximum transmit power Pcmax1 after AI adjustment. The base station calculates the PH value of the uplink signal or channel transmitted by the UE based on the values ​​of Pcmax1 and Pactual. In this method, the UE does not need to calculate and report the PH value to the network device.

[0264] After the UE accesses the network, the UE reports the maximum transmission power Pcmax1 in two ways: 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. The maximum power offset value refers to the offset value between the maximum transmission power Pcmax1 after AI adjustment and the maximum transmission power Pcmax2 before AI adjustment.

[0265] The base station calculates PH as follows: PH value = Pcmax1 - Pactual (corresponding to method 1 above, the UE directly reports Pcmax1 in the UE capability report), or the base station calculates PH as follows: PH value = Pcmax2 + offset - Pactual (corresponding to method 2 above, the UE reports the offset value of the maximum power in the UE capability report).

[0266] In UE capability reporting, the power level is reported, and the maximum transmit power value of the signal or channel is determined based on the power level.

[0267] The actual transmission power Pactual of the signal or channel can be carried in the MAC CE or physical layer control signaling to indicate to the base station. It can directly indicate the actual transmission power value Pactual, or the protocol defines a mapping table between the index and the corresponding actual transmission power value. The UE indicates the actual transmission power value Pactual by indicating the index to the network device.

[0268] For example, if the actual transmit power range determined by the UE is [P1, P2], then the indicated step size is 1 dBm. There are K values ​​between [P1, P2], so log2(K) bits are used to indicate the power index. The base station determines the actual transmit power value of the uplink channel or signal based on the index.

[0269] Example 2: When Pcmax changes, the UE reports to the base station the actual transmit 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. The base station calculates the PH value of the uplink signal or channel transmitted by the UE based on Pactual, offset value offset and Pcmax2.

[0270] For Pcmax2, after the UE accesses the network, the UE reports Pcmax2 in the UE capability report.

[0271] The offset value is the offset of the maximum transmit power Pcmax1 after AI adjustment relative to the maximum transmit power value Pcmax2 of the UE before AI adjustment.

[0272] The base station calculates the pH value based on Pcmax2, Pactual, and offset using the following formula.

[0273] The base station Pactual and the offset values ​​offset and Pcmax2 are used to calculate PH according to the following formula: PH value = Pcmax2 + offset - Pactual.

[0289] f b,f,c (i,l) represents the closed-loop power value, which is the power adjustment value given to the UE by the base station based on the measurement determination.

[0290] The power formula for SRS can be:

[0291] Among them, P CMAX,f,c (i) represents the maximum transmit power value of the UE;

[0292] P O_SRS,b,f,c (q s That is, based on the SRS resource set q s The target power value has been determined.

[0293] 10log 10 (2 μ ·M SRS,b,f,c (i) is the normalized power value on the frequency domain resources occupied by the SRS;

[0294] α SRS,b,f,c (q s () represents the road loss compensation coefficient;

[0295] PL b,f,c (q d The path loss value between the UE and the base station is determined by the UE based on the reference signal measurement.

[0296] h b,f,c (i,l) represents the closed-loop power value, which is the power adjustment value that the base station indicates to the UE based on the measurement.

[0297] P represents CMAX,f,c The linear value of (i).

[0298] The power formula for 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}

[0299] Among them, P PRACH,target,f,c The target received power value;

[0300] PL b,f,c This is the path loss value between the UE and the base station, determined by the UE based on the reference signal.

[0301] The sensing RS transmit power can be determined in the following ways.

[0302] Method 1 reuses the power control formula of the Sensing RS for uplink channel measurement at the base station. The power formula of the Sensing RS is:

[0303] Method 2: Reuse the power control formula for positioning using SRS. The power formula for sensing RS is:
