Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a method for reporting power change information and related equipment. Background Art

[0002] The UE (User Experience) power level represents the maximum transmit power of the UE, which may vary across different operating frequency bands. In existing protocols, a UE may have multiple power levels. The UE power level delta refers to the specific power value a UE experiences when transitioning from one power level to another.

[0003] P-MPR (Power Management-Maximum Power Reduction) is a setting to ensure compliance with RF energy exposure requirements.

[0004] In existing protocol mechanisms, power level changes, or P-MPR values, are proactively reported by the UE, preventing the base station from obtaining real-time information about the UE's power changes. Furthermore, the P-MPR value is defined only in FR2 (Frequency Range 2, the second frequency band of the 5G NR system, i.e., 24.25 GHz to 52.6 GHz). If the power headroom in FR1 (Frequency Range 1, the first frequency band of the 5G NR system, i.e., 450 MHz to 6 GHz) is significantly increased due to the impact of SAR (Specific Absorption Rate), the base station cannot determine what is happening to the UE. This may result in the base station attempting to continuously increase the UE's power through TPC (Transmit Power Control), but the UE's power cannot be increased. Therefore, a method is urgently needed to report the UE's power level changes and, at least in FR1, the P-MPR value.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0056] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Some of the block diagrams shown in the accompanying drawings are functional entities that do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0058] For ease of understanding, before introducing the embodiments of the present disclosure, several terms involved in the embodiments of the present disclosure are first explained as follows:

[0059] UE level change: In existing protocols, a UE may have multiple power levels, typically with a 3dB difference between each power level. If a UE changes from one power level to another, a power level change occurs. The specific power value of the change is called the power level change.

[0060] Maximum Power Reduction Report: P-MPR, short for Power Management Maximum Power Reduction Report, is a setting to ensure compliance with RF energy exposure regulations.

[0061] The specific implementation of the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0062] like Figure 1 As shown, the system architecture includes a terminal 101, a network 102 and a network-side device 103; wherein, the terminal 101 reports power change information used to characterize the change of its transmission power to the network-side device 103, so that the network-side device 103 can control the terminal 10 accordingly according to the power change information of the terminal 101.

[0063] The network 102 is a medium for providing a communication link between the terminal 101 and the network-side device 103 , and can be a wired network or a wireless network.

[0064] Optionally, the above-mentioned wireless network or wired network uses standard communication technologies and / or protocols. The network is typically the Internet, but it can also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a private network or any combination of a virtual private network). In some embodiments, technologies and / or formats including Hypertext Markup Language (HTML), Extensible Markup Language (XML), etc. are used to represent data exchanged over the network. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPSec), etc. can be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies can also be used to replace or supplement the above-mentioned data communication technologies.

[0065] Optionally, the terminal in the embodiment of the present disclosure may also be referred to as UE (User Equipment). In a specific implementation, the terminal may be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (PDA), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device, etc. It should be noted that the specific type of the terminal is not limited in the embodiment of the present invention.

[0066] The network side device may be a base station, a relay, or an access point, etc. The base station may be a base station of 5G or later versions (e.g., 5G NR NB), or a base station in other communication systems (e.g., an eNB base station). It should be noted that the specific type of the network side device is not limited in the embodiments of the present disclosure.

[0067] Those skilled in the art will know that Figure 1The number of terminals, networks, and network-side devices in the figure is merely illustrative, and any number of terminals, networks, and network-side devices may be provided according to actual needs. This disclosure does not limit this.

[0068] Under the above system architecture, an embodiment of the present disclosure provides a method for reporting power change information, which can be executed by any electronic device with computing and processing capabilities.

[0069] In some embodiments, the power change information reporting method provided in the embodiments of the present disclosure can be executed by the terminal of the above-mentioned system architecture; in other embodiments, the power change information reporting method provided in the embodiments of the present disclosure can be executed by the terminal and network side equipment in the above-mentioned system architecture through interaction.

[0070] Figure 2 A flow chart of a method for reporting power change information in an embodiment of the present disclosure is shown as follows: Figure 2 As shown, the power change information reporting method provided in the embodiment of the present disclosure includes the following steps:

[0071] S202: Report power change information of the terminal, where the power change information is used to represent changes in the transmission power of the terminal.

[0072] It should be noted that the power change information in the embodiments of the present disclosure may be any information capable of characterizing a change in the transmission power of a terminal. The transmission power herein may be the transmit power of a signal transmitted by the terminal or the receive power of a signal received by the terminal. In some embodiments, the power change information in the embodiments of the present disclosure may include, but is not limited to, a power level change and / or a power management maximum power reduction (P-MPR) value.

[0073] Table 1 shows the three power levels of the terminal UE specified in the current protocol. The protocol stipulates that when the uplink duty cycle of the UE meets certain conditions, the power level needs to be backed off. That is, if the symbol transmission duty cycle within a certain uplink time interval exceeds the preconfigured or default threshold, power backoff is required. The backoff value depends on the percentage interval of the over-limit. However, this is the UE's autonomous backoff behavior after exceeding the limit. Although the base station can also measure the duty cycle to roughly know whether the UE needs to backoff, the base station cannot fully grasp the power changes of the UE, especially in scenarios such as carrier aggregation. It can only make a rough judgment. Therefore, the base station is generally unaware of the event that the UE backs off the power level.

[0074] Table 1

[0075] Power level name Maximum transmit power Lowest fallback level PC1.5 29dBm PC3 PC2 26dBm PC3 PC3 23dBm PC3

[0076] When a terminal transmits radio frequency signals, some of them may strike the human body. For example, if a person is holding a mobile phone and their body acts as an obstacle between the terminal and the base station, electromagnetic waves can penetrate the body and be transmitted. In this scenario, the ITU defines radio frequency energy exposure as the limit value for electromagnetic wave exposure to which humans are exposed. This indicator can be roughly understood as the specific absorption rate (SAR) for radio frequency signals below 6 GHz, the maximum permissible exposure (MPE) for radio frequency signals above 6 GHz, and the total exposure (TER) of the two combined. This regulation specifies the limit value of RF energy that the human body can tolerate over a specific time period. It is an average value corresponding to the SAR and MPE values ​​over a specific period of time.

[0077] During the above process, if the SAR or MPE exceeds the ITU limit for a certain period of time, power reduction is required. Because the MPE reduction amount is slightly larger in FR2, 3GPP defines the P-MPR indicator as a reporting indicator for the UE's fallback power range, which is reported in the PHR to assist the base station with power management. P-MPR, or Maximum Power Reduction Report for Power Management, is set to ensure compliance with RF energy exposure regulations. This indicator is an autonomous behavior of the UE and is completely unknown to the base station. The current P-MPR value can only be determined through PHR reporting in FR2.

[0078] In some embodiments, when the above S202 is specifically implemented, the power change information of the terminal may be reported through a power headroom report PHR.

[0079] In some embodiments, when the power change information of the terminal is reported through the PHR, it may include but is not limited to the following methods: ① reporting the power level change and / or P-MPR value of the terminal by reusing the existing domain in the PHR; ② reporting the power level change of the terminal by reusing the existing domain in the PHR, and / or reporting the P-MPR value of the terminal by adding a new domain in the PHR; ③ reporting the power level change of the terminal by adding a new domain in the PHR, and / or reporting the P-MPR value of the terminal by reusing the existing domain in the PHR; ④ reporting the power level change and / or P-MPR value of the terminal by adding a new domain in the PHR; ⑤ reporting the power level change and / or P-MPR value of the terminal by creating a new PHR.

Figure 5 As shown, the network side device includes: a power change information acquisition module 501, which is used to receive power change information reported by the terminal, wherein the power change information is used to represent the change of the transmission power of the terminal.

[0127] In some embodiments, the power change information may include but is not limited to: a power level change amount and / or a power management maximum power reduction P-MPR value.

[0128] It should be noted that the examples and application scenarios implemented by the various modules in the above-mentioned network-side device embodiments are the same as those implemented by the steps in the corresponding method embodiments, but are not limited to the contents disclosed in the above-mentioned method embodiments. It should be noted that the above-mentioned modules, as part of the apparatus, can be executed in a computer system, such as a set of computer-executable instructions.

[0129] Several specific examples are given below to illustrate in detail the method for reporting power change information provided in the embodiments of the present disclosure:

[0130] Example 1: ΔP PowerClass The P-MPR value is reported by reusing the existing PHR field and reporting in a single entity PHR, such as reusing the MPE field, the R field, or both fields. PowerClass And / or the change in the P-MPR value reported can be a fallback value or an increase value.

[0131] a) In the case where the MPE field is not reported as the MPE of FR2 (i.e. the P field is set to 1), this field will be used as the ΔP PowerClass The reported domain, 2 bits will be used to represent ΔP PowerClass The reported value can be set to at least one of 0dB, 3dB, 4.7dB, and 6dB. In one embodiment, "00" can represent 0dB, "01" represents 3dB, "10" represents 4.7dB, and "11" represents 6dB. If the MPE field is enabled (i.e., the P field is set to 0), the MPE field will be reported as the FR2 value of the P-MPR value, consistent with the existing mechanism.

[0132] The iR field can also be enabled to indicate whether the change is an increase or decrease. For example, a value of 0 in the iR field indicates a decrease, while a value of 1 indicates an increase, or vice versa. The increase or decrease value can be relative to the previous increase or decrease, or relative to the first threshold.

[0133] ii. The R field may not be enabled and no corresponding indication is given.

[0134] iii. The first threshold may be the power level value reported by the UE's initial capability, or may be the maximum power value (eg, p-max value) initially configured by the base station for the UE.

[0135] like Figure 6 The functions of the PHR information fields are as follows:

[0136] R field: reserved bit, or used to indicate the reported ΔP PowerClass And / or whether the P-MPR value is an increase or decrease.

[0137] PH field: used to indicate the power headroom level, with a size of 6 bits, corresponding to a total of 64 type 1 PHR value ranges from 0 to 63.

[0138] P Cmax : Used to indicate the maximum transmit power. It is 6 bits long and corresponds to a total of 64 maximum transmit power value ranges from 0 to 63. This value can be used to calculate the associated pH.

[0139] P domain: If configured as mpe-Reporting-FR2 and the serving cell operates in the FR2 frequency band, if the P-MPR value is lower than the P-MPR_00 value to meet the MPE requirement, the MAC entity will set this domain to 0, otherwise it will be set to 1. If mpe-Reporting-FR2 is not configured or the serving cell operates in the FR1 frequency band, this domain is used to indicate whether power fallback is performed under power control. If power fallback caused by power control is not applied, the corresponding P Cmax field will have different values, then the MAC entity shall set the P field to 1.

[0140] MPE field: If the configuration is mpe-Reporting-FR2 and the serving cell operates in the FR2 frequency band, if the P field value is 1, this field is used to indicate the corresponding power backoff value to meet the MPE requirement. This field consists of 2 bits. If this field is 0, it will be used as ΔP PowerClass The reported domain, 2 bits will be used to represent ΔP PowerClass The reported value can be set to at least one of 0dB, 3dB, 4.7dB and 6dB.

[0141] b) In the case where the MPE field is not reported as the MPE of FR2 (i.e. the P field is set to 1), this field will be used as the ΔP PowerClass The reported domain uses two bits to indicate the value of the value. One bit indicates an increase or decrease relative to the first domain value, or a previous increase or fallback value. For example, 0 represents a fallback value, 1 represents an increase, or vice versa. The other bit indicates the specific value, which can be at least one of 0dB, 3dB, 4.7dB, and 6dB. If the MPE domain is enabled (i.e., the P domain is set to 0), the MPE will be reported as the FR2 value of the P-MPR value, consistent with the existing mechanism.

[0142] The iR field can be enabled simultaneously and used in conjunction with the additional one-bit information in the MPE field to indicate the value. For example, by combining the R field with the bit used to indicate the value in the MPE, these two bits can be used to indicate whether the reported value is at least one of 0dB, 3dB, 4.7dB, and 6dB. Preferably, "00" can represent 0dB, "01" represents 3dB, "10" represents 4.7dB, and "11" represents 6dB.

[0143] ii. The R field may not be enabled and no corresponding indication is given.

[0144] iii. In this solution, the first threshold may be the power level value reported by the UE's initial capability, or the maximum power value (eg, p-max value) initially configured by the base station for the UE.

[0145] like Figure 6 The functions of the PHR information fields are as follows:

[0146] R field: reserved bits, or can be used for ΔP PowerClass Or a joint indication when the P-MPR value is reported.

[0147] PH: Indication of the power headroom level, 6 bits, corresponding to a total of 64 type 1 PHR value ranges from 0 to 63.

[0148] P Cmax Field: Maximum transmit power indication, 6 bits, corresponding to a total of 64 maximum transmit power value ranges from 0 to 63. This value can be used to calculate the associated pH.

[0149] P field: When mpe-Reporting-FR2 is configured and the serving cell operates in the FR2 band, the MAC entity shall set this field to 0 if the P-MPR value is lower than the P-MPR_00 value to meet the MPE requirement, otherwise it shall be set to 1. If mpe-Reporting-FR2 is not configured or the serving cell operates in the FR1 band, this field is used to indicate whether power fallback is performed under power control. If power fallback due to power control is not applied, the corresponding PCmax field will have a different value, and the MAC entity shall set the P field to 1.

[0150] MPE field: If the configuration is mpe-Reporting-FR2 and the serving cell operates in the FR2 frequency band, and the P field value is 1, this field is used to indicate the corresponding power fallback value to meet the MPE requirement. This field consists of 2 bits. If the P field value is 0, this field will be used as ΔP PowerClass The reported domain. Two bits may be used to indicate: one bit indicates an increase or decrease relative to the first domain value, or an increase or decrease relative to the previous value; and the other bit indicates the specific value.

[0151] c) In the case where the MPE field is not reported as the MPE of FR2 (i.e. the P field is set to 1), this field will be used as the ΔP PowerClass Report the P-MPR value of FR1. If it is ΔP PowerClass For reporting, refer to a) or b). If the P-MPR value of FR1 is reported, the mechanism will refer to the MPE reporting mechanism of FR2.

[0152] The iR field can be enabled at the same time to indicate that the reported value is ΔP. PowerClass Or the P-MPR value of FR1. For example, 0 means that the value reported in the MPE domain is ΔP PowerClass, 1 means that the P-MPR value reported in this MPE domain is FR1, or vice versa. If the R domain is enabled, all solutions in solution a) or b) that enable the R domain are not applicable in this solution.

[0153] ii. Do not enable the R domain. Since the reporting mechanism of P-MPR value in FR1 is the same as that in FR2, ΔP is directly performed through the P domain. PowerClass For example, when the P field is set to 0, the P-MPR value is reported; when the P field is set to 1, ΔPPowerClass is reported.

[0154] iii. Existing RRC signaling can be reused, but its scope of application can be expanded. For example, mpe-Reporting-FR2 can also be used to report the P-MPR value in FR1. New RRC signaling can also be configured to indicate the reporting of the P-MPR value in FR1, such as mpe-Reporting-FR1.

[0155] iv. The first threshold may be the power level value reported by the UE's initial capability, or may be the maximum power value (eg, p-max value) initially configured by the base station for the UE.

[0156] like Figure 7 The functions of the PHR information fields are as follows:

[0157] R field: reserved bit, or used to indicate ΔP PowerClass Or reporting of the P-MPR value of FR1.

[0158] PH: Indication of the power headroom level, 6 bits, corresponding to a total of 64 type 1 PHR value ranges from 0 to 63.

[0159] P Cmax Field: Maximum transmit power indication, 6 bits, corresponding to a total of 64 maximum transmit power value ranges from 0 to 63. This value can be used to calculate the associated pH.

[0160] P domain: When mpe-Reporting-FR2 or possible new RRC signaling is configured, if the P-MPR value is lower than the P-MPR_00 value or the first threshold, no power backoff is required to meet the requirements of MPE or SAR, then the MAC entity will set this domain to 0, otherwise it will be set to 1. In addition, the P domain can also be used to perform ΔP PowerClass Or an indication of P-MPR value reporting.

[0161] MPE / SAR orΔPPowerClass: If the configuration is mpe-Reporting-FR2 or possible new RRC signaling, and the P field value is 1, then this field is used to indicate the corresponding power backoff value to meet the MPE or SAR requirements. This field consists of 2 bits. If the P field is 0, then this field will be used as ΔP PowerClass For MPE, the original mechanism (including FR1) will be used. PowerClass , 2 bits may be used to represent them separately, 1 bit is used to represent the increase or decrease relative to the first domain value, or it can be the increase value or fallback value relative to the previous time, and the other bit is used to represent the specific value size; or, 2 bits will be used to represent the power change value as a whole, and the reported value can be set to at least one of 0dB, 3dB, 4.7dB and 6dB.

[0162] a) In the case where the MPE field is not reported as the MPE of FR2 (i.e. the P field is set to 1), this field will be used as the ΔP PowerClass Report the P-MPR value of FR1. If it is ΔP PowerClass Reporting, refer to scheme a) or b). If it is FR1 P-MPR value reporting, a new reporting mechanism will be defined for FR1 P-MPR value reporting. For example, for FR1 P-MPR value reporting, it is considered that all 2 bits of the MPE field will be used to indicate the range of change of the P-MPR value, and the report can be at least one of 0dB, 0~3dB, 3~6dB, and >6dB. Preferably, it is considered that the indication "00" represents 0dB, the indication "01" represents 0~3dB, "10" represents 3~6dB, and "11" represents >6dB; or, it is considered that the 2 bits of the MPE field are reported separately, and 1 bit is used to indicate an increase or decrease relative to the first field value, or it can be an increase value or fallback value relative to the previous time. For example, 0 represents a fallback value, 1 represents an increase value, or vice versa. The other bit is used to indicate a specific range size, which can be at least one of 0 dB, 0-3 dB, 3-6 dB, and >6 dB.

[0163] The iR field can be enabled at the same time to indicate that the reported value is ΔP. PowerClass Or the P-MPR value of FR1. For example, 0 means that the value reported in the MPE domain is ΔP PowerClass , 1 means that the P-MPR value reported in this MPE domain is FR1, or vice versa. If the R domain is enabled, all solutions in solution a) or b) that enable the R domain are not applicable in this solution.

[0164] ii. If the R field is disabled, the P field is used to distinguish between FR2 and non-FR2 MPE reports. A joint perspective is adopted for non-FR2 MPE reporting indications. Specifically, "00" is considered to represent a power change of up to 0dB, "01" represents a power change of up to 3dB, "10" represents a power change of up to 6dB, and "11" represents a power change exceeding 6dB. Alternatively, the two bits of the MPE field are considered to be reported separately: one bit indicates an increase or decrease relative to the first field value, or a previous increase or fallback value, and the other bit represents the value. For example, "0" represents a change of up to 3dB or 6dB, and "1" represents a change exceeding 3dB or 6dB. In this joint perspective, the power change is not distinguished by which indicator. The network can consider the power change to be caused by either the change in power level or the FR1 P-MPR value, and perform corresponding power control.

[0165] iii. Configure new RRC signaling to indicate the reporting of the P-MPR value for FR1, such as mpe-Reporting-FR1.

[0166] iv. The first threshold may be the power level value reported by the UE's initial capability, or may be the maximum power value (eg, p-max value) initially configured by the base station for the UE.

[0167] like Figure 7 The functions of the PHR information fields are as follows:

[0168] R field: reserved bit, or used to indicate ΔP PowerClass and / or reporting of the P-MPR value of FR1.

[0169] PH field: used to indicate the power headroom level, with a size of 6 bits, corresponding to a total of 64 type 1 PHR value ranges from 0 to 63.

[0170] P Cmax Field: used to indicate the maximum transmit power indication, with a size of 6 bits, corresponding to a total of 64 maximum transmit power value ranges from 0 to 63. This value can be used to calculate the related PH.

[0171] P field: If configured as mpe-Reporting-FR2 or possible new RRC signaling, if the P-MPR value is lower than the P-MPR_00 value or the first threshold, no power fallback is required to meet the requirements of MPE or SAR, then the MAC entity will set this field to 0, otherwise it will be set to 1. If mpe-Reporting-FR2 is not configured or the serving cell operates in the FR1 frequency band, this field is used to indicate whether power fallback is performed under power control. If power fallback caused by power control is not applied, the corresponding P Cmax The MAC entity shall set the P field to 1. Alternatively, the P field may be used to perform ΔP PowerClass Or an indication of P-MPR value reporting.

[0172] MPE / SAR or ΔP PowerClass :If the configuration is mpe-Reporting-FR2 or possible new RRC signaling, and the P field value is 1, then this field is used to indicate the power backoff value corresponding to the FR2 frequency band to meet the MPE requirements. This field consists of 2 bits. If the P field value is 0, it will be used as ΔP PowerClass Or the power backoff value corresponding to the FR1 frequency band to meet the MPE requirement. Two bits may be used to represent them respectively, one bit is used to represent the increase or decrease relative to the first domain value, or the increase or fallback value relative to the previous one, and the other bit is used to represent the specific value size; or, two bits will be used to represent ΔP PowerClass Or the change in the power backoff value corresponding to the FR1 frequency band.

[0173] Example 2: ΔP PowerClass The new PHR field is used for reporting, while the P-MPR value is reported by reusing the existing PHR field in a single-entity PHR. For example, the MPE field is reused. This may require a new MAC-CE or a new LCID.

[0174] a)ΔP PowerClass Report in a new field, for example, by adding a new field to the single entity PHR field. 2 bits will be used to represent ΔP PowerClass The reported value can be set to at least one of 0dB, 3dB, 4.7dB, and 6dB. Preferably, "00" represents 0dB, "01" represents 3dB, "10" represents 4.7dB, and "11" represents 6dB. The P-MPR value is reported using the existing MPE field and is reported only in FR2, consistent with the existing mechanism.

[0175] like Figure 8 The functions of the PHR information fields are as follows:

[0176] R field: 1 bit, reserved bit, or used to indicate the reporting of the ΔPPowerClass or FR1 P-MPR value.

[0177] PH field: used to indicate the power headroom level, 6 bits, corresponding to a total of 64 type 1 PHR value ranges from 0 to 63.

[0178] P Cmax Field: used to indicate the maximum transmit power, 6 bits, corresponding to a total of 64 maximum transmit power value ranges from 0 to 63. This value can be used to calculate the related PH.

[0179] P field: If mpe-Reporting-FR2 is configured and the serving cell operates in the FR2 frequency band, and the P-MPR value is lower than the P-MPR_00 value to meet the MPE requirement, the MAC entity shall set this field to 0; otherwise, it shall be set to 1. If mpe-Reporting-FR2 is not configured or the serving cell operates in the FR1 frequency band, this field is used to indicate whether power backoff is performed under power control. If power backoff due to power control is not applied, the corresponding PCmax field will have a different value, and the MAC entity shall set the P field to 1.

[0180] MPE field: If the configuration is mpe-Reporting-FR2 and the serving cell operates in the FR2 frequency band, and the P field value is 1, this field is used to indicate the corresponding power backoff value to meet the MPE requirement. This field consists of 2 bits. If the above conditions are not met, this field is reserved and the R bit is reserved.

[0181] ΔP PowerClass Field: 2 bits will be used to represent ΔP PowerClass The reported value can be set to at least one of 0dB, 3dB, 4.7dB and 6dB.

[0182] R field: 6 bits, reserve bits.

[0183] b)ΔP PowerClass Reporting is performed in a new domain, for example, by adding a new domain to the single-entity PHR domain. Two bits are used to indicate each, with one bit representing an increase or decrease relative to the first domain value, or an increase or fallback value relative to the previous one. For example, 0 represents a fallback value, 1 represents an increase, or vice versa. The other bit is used to indicate the specific value, which can be at least one of 0dB, 3dB, 4.7dB, and 6dB. The P-MPR value reuses the existing MPE domain for reporting and is reported only in FR2, consistent with the existing mechanism.

[0184] i. In this solution, the first threshold may be the power level value reported by the UE's initial capability, or the maximum power value (eg, p-max value) initially configured by the base station for the UE.

[0185] like Figure 8 The functions of the PHR information fields are as follows:

[0186] R field: 1 bit, reserved bit, or can be used to indicate the reporting of the ΔPPowerClass or P-MPR value of FR1.

[0187] PH field: Indication of the power headroom level, 6 bits, corresponding to a total of 64 type 1 PHR value ranges from 0 to 63.

[0188] PCmax field: Maximum transmit power indication, 6 bits, corresponding to a total of 64 maximum transmit power value ranges from 0 to 63. This value can be used to calculate the associated PH.

[0189] P field: If mpe-Reporting-FR2 is configured and the serving cell operates in the FR2 frequency band, and the P-MPR value is lower than the P-MPR_00 value to meet the MPE requirement, the MAC entity shall set this field to 0; otherwise, it shall be set to 1. If mpe-Reporting-FR2 is not configured or the serving cell operates in the FR1 frequency band, this field is used to indicate whether power backoff is performed under power control. If power backoff due to power control is not applied, the corresponding PCmax field will have a different value, and the MAC entity shall set the P field to 1.

[0190] MPE field: If the configuration is mpe-Reporting-FR2 and the serving cell operates in the FR2 frequency band, and the P field value is 1, this field is used to indicate the corresponding power backoff value to meet the MPE requirement. This field consists of 2 bits. If the above conditions are not met, this field is reserved and the R bit is reserved.

[0191] ΔPPowerClass field: Two bits are used to indicate whether the power level is increasing or decreasing relative to the first field value, or increasing or decreasing relative to the previous value. The other bit indicates the specific value, which can be at least one of 0dB, 3dB, 4.7dB, and 6dB.

[0192] R field: 6 bits, reserved bits.

[0193] c) ΔPPowerClass is reported in a new domain, for example, by adding a new domain to the single-entity PHR domain. The reporting scheme can refer to a) and b). P-MPR values ​​are reported using the existing MPE domain, consistent with the existing mechanism in FR2. They will also be reported in FR1, reusing the existing MPE domain using the same mechanism as the P-MPR value mechanism in FR2. The P domain is used to distinguish corresponding values. For example, a P domain value of 1 indicates a P-MPR value report for FR1, and a P domain value of 0 indicates a P-MPR value report for FR2.

[0194] i. New RRC signaling can be configured to indicate the reporting of the P-MPR value for FR1, such as mpe-Reporting-FR1.

[0195] like Figure 8 The functions of the PHR information fields are as follows:

[0196] R field: 1 bit, reserved bit.

[0198] PCmax field: Maximum transmit power indication, 6 bits, corresponding to a total of 64 maximum transmit power value ranges from 0 to 63. This value can be used to calculate the associated PH.

[0199] P field: If mpe-Reporting-FR2 or possible new RRC signaling is configured, if the P field value is 1, then this field is used to indicate the corresponding FR2 power backoff value to meet the MPE requirement, otherwise it is used to indicate the corresponding FR1 power backoff value to meet the SAR requirement. This field consists of 2 bits. If mpe-Reporting-FR2 is not configured or the serving cell operates in the FR1 frequency band, this field is used to indicate whether power backoff is performed under power control. If power backoff caused by power control is not applied, the corresponding PCmax field will have a different value, and the MAC entity shall set the P field to 1.

[0200] MPE / SAR field: If mpe-Reporting-FR2 or possible new RRC signaling is configured, if the P field value is 1, this field is used to indicate the power backoff value for the FR2 band to meet MPE requirements. This field consists of 2 bits. If this field is 0, it is used as the power backoff value for the FR1 band to meet SAR requirements. This field consists of 2 bits and is indicated according to the existing mechanism.

[0202] R field: 6 bits, which are reserve bits.

[0203] a) ΔPPowerClass is reported in a new field, for example, by adding a new field to the single-entity PHR field. The reporting scheme can refer to steps a) and b). The P-MPR value is reported using the existing MPE field, consistent with the existing mechanism in FR2. Reporting in FR1 will also reuse the existing MPE field. Two bits are used to indicate the FR1 P-MPR value range, which can be set to at least one of 0dB, 0-3dB, 3-6dB, and >6dB. Preferably, "00" represents 0dB, "01" represents 0-3dB, "10" represents 3-6dB, and "11" represents >6dB. The P field is used for corresponding differentiation. For example, a P field value of 1 indicates a P-MPR value report for FR1, while a P field value of 0 indicates a P-MPR value report for FR2.

[0204] i. Configure new RRC signaling to indicate the reporting of the P-MPR value for FR1, such as mpe-Reporting-FR1.

[0205] like Figure 9 The functions of the PHR information fields are as follows:

[0206] R field: 1 bit, reserve bit.

[0207] PH field: Indication of the power headroom level, 6 bits, corresponding to a total of 64 type 1 PHR value ranges from 0 to 63.

[0208] PCmax field: Maximum transmit power indication, 6 bits, corresponding to a total of 64 maximum transmit power value ranges from 0 to 63. This value can be used to calculate the associated PH.

[0209] P field: If mpe-Reporting-FR2 or possible new RRC signaling is configured, if the P field value is 1, then this field is used to indicate the corresponding FR2 power backoff value to meet the MPE requirement, otherwise it is used to indicate the corresponding FR1 power backoff value to meet the SAR requirement. This field consists of 2 bits. If mpe-Reporting-FR2 is not configured or the serving cell operates in the FR1 frequency band, this field is used to indicate whether power backoff is performed under power control. If power backoff caused by power control is not applied, the corresponding PCmax field will have a different value, and the MAC entity shall set the P field to 1.

[0210] MPE / SAR Field: If mpe-Reporting-FR2 or possibly new RRC signaling is configured, if the P field value is 1, this field indicates the power backoff value for the FR2 band to meet MPE requirements. This field consists of 2 bits and uses the original mechanism. If this field is 0, it is used as the power backoff value for the FR1 band to meet SAR requirements. This field consists of 2 bits and indicates the FR1 P-MPR value range. The reported value can be set to at least one of 0dB, 0-3dB, 3-6dB, and >6dB. Preferably, the indication "00" represents 0dB, "01" represents 0-3dB, "10" represents 3-6dB, and "11" represents >6dB.

[0211] ΔP PowerClass Domain: Two bits are used to indicate the value of the power level. One bit indicates an increase or decrease relative to the first domain value, or a previous increase or decrease.

[0212] R field: 6 bits, reserved bits.

[0213] a) ΔPPowerClass is reported in a new domain, for example, by adding a new domain to the single-entity PHR domain. The reporting scheme can refer to a) and b). The P-MPR value reuses the existing MPE domain for reporting. In FR2, it is consistent with the existing mechanism. In FR1, it will also be reported, reusing the existing MPE domain. For example, for P-MPR value reporting in FR1, it is assumed that the two bits of the MPE domain are reported separately. One bit is used to indicate an increase or decrease relative to the first domain value, or it can be an increase or fallback value relative to the previous one. For example, 0 represents a fallback value, 1 represents an increase value, or vice versa. The other bit is used to indicate the specific range size, which can be at least one of 0dB, 0~3dB, 3~6dB, and >6dB.

[0214] i. New RRC signaling can be configured to indicate the reporting of the P-MPR value for FR1, such as mpe-Reporting-FR1.

[0218] P Cmax Field: Maximum transmit power indication, 6 bits, corresponding to a total of 64 maximum transmit power value ranges from 0 to 63. This value can be used to calculate the associated pH.

[0219] P field: If configured as mpe-Reporting-FR2 or possible new RRC signaling, if the P field value is 1, then this field is used to indicate the corresponding FR2 power backoff value to meet the MPE requirement, otherwise it is used to indicate the corresponding FR1 power backoff value to meet the SAR requirement. This field consists of 2 bits. If mpe-Reporting-FR2 is not configured or the serving cell operates in the FR1 frequency band, this field is used to indicate whether power backoff is performed under power control. If power backoff caused by power control is not applied, the corresponding PCmax field will have a different value, and the MAC entity shall set the P field to 1.

[0220] MPE / SAR Field: If configured as mpe-Reporting-FR2 or possible new RRC signaling, and the P field value is 1, this field indicates the power backoff value for the FR2 band to meet MPE requirements. This field consists of 2 bits and uses the original mechanism. If the P field value is 0, it is used as the power backoff value for the FR1 band to meet SAR requirements. This field consists of 2 bits, both of which are reported separately. One bit indicates an increase or decrease relative to the first field value, or an increase or fallback value relative to the previous value. For example, 0 indicates a fallback value, 1 indicates an increase, or vice versa. The other bit indicates the specific range, which can be at least one of 0dB, 0-3dB, 3-6dB, or >6dB.

[0221] ΔPPowerClass field: Two bits are used to indicate whether the power level is increased or decreased relative to the first field value, or whether it is increased or decreased relative to the previous value.

[0222] R field: 6 bits, which are reserve bits.

[0223] Example 3: ΔPPowerClass is reported using a new PHR field. The P-MPR value is also reported using the new field in a single-entity PHR. This may require a new MAC-CE or a new LCID.

[0224] a) ΔPPowerClass is reported in the new domain, and the P-MPR value range of FR1 is also reported in the new domain. The two are reported in different new domains. The reporting method can refer to the non-joint reporting scheme in Example 1 and Example 2.

[0225] i. Configure new RRC signaling to indicate the reporting of the P-MPR value for FR1, such as mpe-Reporting-FR1.

[0226] like Figure 10 The functions of the PHR information fields are as follows:

[0227] R field: 1 bit, reserved bit.

[0228] PH field: Indication of the power headroom level, 6 bits, corresponding to a total of 64 type 1 PHR value ranges from 0 to 63.

[0229] P Cmax Field: Maximum transmit power indication, 6 bits, corresponding to a total of 64 maximum transmit power value ranges from 0 to 63. This value can be used to calculate the associated pH.

[0230] P domain: If configured as mpe-Reporting-FR2 or possible new RRC signaling, and the P domain value is 1, then this domain is used to indicate the corresponding FR2 power fallback value to meet the MPE requirement, otherwise it is used to indicate the corresponding FR1 power fallback value to meet the SAR requirement. This domain consists of 2 bits. If mpe-Reporting-FR2 is not configured or the serving cell operates in the FR1 frequency band, this domain is used to indicate whether power fallback is performed under power control. If power fallback caused by power control is not applied, the corresponding P Cmax field will have different values, then the MAC entity shall set the P field to 1.

[0231] MPE field: If the configuration is mpe-Reporting-FR2 and the serving cell operates in the FR2 frequency band, and the P field value is 1, this field is used to indicate the corresponding power backoff value to meet the MPE requirement. This field consists of 2 bits. If the above conditions are not met, this field is reserved and the R bit is reserved.

[0232] SAR field: If new RRC signaling is configured and the serving cell operates in the FR1 frequency band, if the P field value is 1, this field is used to indicate the corresponding power backoff value to meet the SAR requirement. This field consists of 2 bits. If the above conditions are not met, this field is reserved and the R bit is reserved.

[0233] ΔP PowerClass : 2 bits will be used to represent respectively, 1 bit is used to represent the rise or fall relative to the first domain value, or the rise or fall value relative to the previous one. The other bit is used to represent the specific value size, which can be at least one of 0dB, 3dB, 4.7dB and 6dB. Alternatively, 2 bits will be used to represent ΔP PowerClass The corresponding power level change value.

[0234] R field: 6 bits, which are reserve bits.

[0235] b)ΔP PowerClass The report is made in the new domain, and the P-MPR value range of FR1 will also be reported in the new domain. The two are reported in the same new domain. The reporting method can refer to the joint reporting scheme in Example 1 and Example 2.

[0236] The iR field can be enabled at the same time to indicate that the reported value is ΔP. PowerClass Or the P-MPR value of FR1. For example, 0 means that the value reported in the MPE domain is ΔP PowerClass , 1 means that the P-MPR value reported in the MPE domain this time is FR1, or vice versa.

[0237] ii. Add a new field to indicate whether the reported value is ΔPPowerClass or the P-MPR value of FR1. For example, 0 indicates that the reported value in the MPE field is ΔPPowerClass, and 1 indicates that the reported value in the MPE field is the P-MPR value of FR1, or vice versa.

[0238] iii. Do not enable any new domains and use a joint reporting method, such as d-ii in Example 1.

[0239] like Figure 11 The functions of the PHR information fields are as follows:

[0240] R field: 1 bit, reserve bit, can also be used to indicate whether the reported value is ΔPPowerClass or FR1 P-MPR value.

[0241] PH field: Indication of the power headroom level, 6 bits, corresponding to a total of 64 type 1 PHR value ranges from 0 to 63.

[0242] PCmax field: Maximum transmit power indication, 6 bits, corresponding to a total of 64 maximum transmit power value ranges from 0 to 63. This value can be used to calculate the associated PH.

[0243] P field: If configured as mpe-Reporting-FR2 or possible new RRC signaling, and the P field value is 1, then this field is used to indicate the corresponding FR2 power backoff value to meet the MPE requirement, otherwise it is used to indicate the corresponding FR1 power backoff value to meet the SAR requirement. This field consists of 2 bits. If mpe-Reporting-FR2 is not configured or the serving cell operates in the FR1 frequency band, this field is used to indicate whether power backoff is performed under power control. If power backoff caused by power control is not applied, the corresponding PCmax field will have a different value, and the MAC entity shall set the P field to 1.

[0244] MPE field: If the configuration is mpe-Reporting-FR2 and the serving cell operates in the FR2 frequency band, and the P field value is 1, this field is used to indicate the corresponding power backoff value to meet the MPE requirement.

[0245] SAR or ΔP PowerClass Field: If the configuration is new RRC signaling and the serving cell operates in the FR1 frequency band, and the P field value is 1, then this field is used to indicate the corresponding power backoff value to meet the SAR requirement or ΔP PowerClassThis field is composed of 2 bits. A joint perspective is adopted to view the indication information during reporting. That is, "00" is considered to represent a power change of up to 0dB, "01" represents a power change of up to 3dB, "10" represents a power change of up to 6dB, and "11" represents a power change of more than 6dB. Alternatively, the two bits of the MPE field are considered to be reported separately, with one bit used to indicate an increase or decrease relative to the first field value, or the previous increase or fallback value, and the other bit to express the value, that is, '0' represents a change of up to 3dB or 6dB, and '1' represents a change of more than 3dB or more than 6dB. When adopting a joint perspective, it is not distinguished which indicator causes the power change. The network can consider the power change to be caused by the change in power level or the power change caused by the P-MPR value of FR1, and perform corresponding power control.

[0246] R field: 6 bits, which are reserve bits, may also be used to indicate whether the reported value is ΔPPowerClass or the P-MPR value of FR1.

[0247] Example 4: ΔP PowerClass and / or P-MPR values ​​are reported entirely through a new PHR, with a new format and a new LCID.

[0251] SAR field: If new RRC signaling is configured and the serving cell operates in the FR1 frequency band, if the P field value is 1, this field is used to indicate the corresponding power backoff value to meet the SAR requirement. This field consists of 2 bits. If the above conditions are not met, this field is reserved and the R bit is reserved.

[0252] ΔP PowerClass Domain: 2 bits will be used to represent respectively, 1 bit is used to represent the rise or fall relative to the first domain value, or the rise or fall value relative to the previous one. The other bit is used to represent the specific value, which can be at least one of 0dB, 3dB, 4.7dB and 6dB. Alternatively, 2 bits will be used to represent ΔP PowerClass The corresponding power level change value.
