In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0136] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. 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.

[0137] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure.

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, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0139] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0140] In some embodiments, the terminal's electromagnetic radiation safety standards for human body are expressed internationally using the electromagnetic wave absorption ratio or specific absorption rate, namely SAR (Specific Absorption Rate), and the maximum permissible exposure, namely MPE (Maximum Permissible Exposure). The former is mainly aimed at low frequency bands, such as bands below 6 GHz, while the latter is mainly aimed at millimeter wave bands.

[0141] In some embodiments, in order to reduce the impact of terminal transmission on human safety, the terminal usually adopts a power reduction method (such as power fallback P-MPR (maximum power reduction)), that is, the terminal's transmission power is not allowed to exceed a certain limit at all times. Although this method can help the terminal reduce the impact on human safety, it will also cause a relatively large impact on the terminal's uplink coverage, and may even cause uplink failure. To this end, some terminals use dynamic power control and exposure time averaging algorithms to intelligently adjust power to meet SAR requirements (terminals with this capability are referred to as supporting intelligent transmission capabilities here). Through real-time control and management of the radio frequency power of wireless communication terminal equipment, its average power over time does not exceed a certain limit requirement. For details, please refer to Figures 1B and 1C.

[0142] In some embodiments, the advantage of the dynamic power control and exposure time averaging algorithm is that the terminal transmission power may not be subject to power limit (P limit ) limit, a higher power can be transmitted, as long as the average power within a period of time does not exceed P limit In TDD (Time division duplex) mode, P limit It is related to the uplink duty cycle. Under the same conditions, the smaller the uplink duty cycle, the higher the P limit But the bigger it is.

[0143] In some embodiments, in order to enable the base station to perform better scheduling, such as determining whether to schedule a lower duty cycle, or whether to switch links, the terminal will P limit It is very beneficial to report it as auxiliary information.

[0144] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the present disclosure embodiment relates to a communication method, which is executed by a communication system 100 and includes:

[0145] Step S201 : Terminal 101 sends a second message to network device 102 .

[0146] In some embodiments, network device 102 receives the second message.

[0147] In some embodiments, the second message indicates that the terminal supports the first function. Optionally, the first function is a function for regulating transmit power. Optionally, the first function is a function for intelligent transmission. Optionally, the first function is a function for using a dynamic power control and exposure time averaging algorithm. The name of the first function is not limited, and it can be, for example, a first capability, an intelligent transmission capability, etc. The method for regulating transmit power can be a dynamic intelligent regulation of transmit power or a conditional trigger-based regulation of transmit power, which is not limited in this disclosure.

[0148] In some embodiments, the name of the second message is not limited, and it can be, for example, terminal capability information, function report, etc.

[0149] In some embodiments, the terminal sends the second message to the network device before sending the first message to the network device.

[0150] In some embodiments, the second message may also be used to indicate other capabilities of the terminal to the network device, for example, indicating to the network device the power level supported by the terminal and / or the maximum transmit power supported by the terminal.

[0151] Step S202 : The network device 102 sends a third message to the terminal 101 .

[0152] In some embodiments, terminal 101 receives a third message.

[0153] In some embodiments, the third message indicates at least one of the following thresholds:

[0154] The first threshold represents the upper limit of the real-time transmit power of the terminal set by the network device;

[0155] The second threshold value represents the upper limit of the actual power threshold value of the terminal set by the network device;

[0156] The third threshold represents the upper limit value of the power threshold offset of the terminal set by the network device.

[0157] In some embodiments, the name of the third message is not limited, and it can be, for example, threshold configuration information, power configuration message, etc.

[0158] In some embodiments, after receiving the third information, the terminal determines at least one of the first threshold, the second threshold, and the third threshold according to the third information.

[0159] In some embodiments, step S202 may be omitted, and the terminal may determine at least one of the first threshold, the second threshold, and the third threshold by itself.

[0160] In step S203 , the network device 102 instructs the terminal 101 to report the transmit power information.

[0161] In some embodiments, the network device may configure a first configuration for the terminal, thereby instructing the terminal to report the transmit power information by default.

[0162] In some embodiments, the network device may send a fourth message to the terminal to instruct the terminal via the fourth message whether to report the transmit power information.

[0163] If the terminal receives an instruction from the network device to report transmit power information, step S204 is executed. That is, before reporting transmit power information to the network device, the terminal must first obtain permission from the network device. For example, if the terminal reports transmit power information in response to an instruction from the network device, step S204 is executed.

[0164] For example, assuming that the transmit power information is carried in the first message and reported, before the terminal sends the first message to the network device, it needs to determine that the network device allows the terminal to send the first message.

[0165] In some embodiments, the implementation method of the terminal determining that the network device allows the terminal to send a first message includes: if the terminal is configured with a first configuration configured by the network device, it can be determined that the network device allows the terminal to send a first message, wherein the first configuration is a configuration for reporting transmission power information, and the name of the first configuration is not limited, and it can be, for example, a specified configuration, specific information, etc.

[0166] In some embodiments, an implementation method of a terminal determining whether a network device allows the terminal to send a first message includes: the terminal receiving a fourth message sent by the network device, and determining whether the network device allows the terminal to send the first message based on the fourth message sent by the network device. If the fourth message instructs the terminal to send the first message, then determining that the network device allows the terminal to send the first message. The fourth message is used to indicate whether the terminal is allowed to send the first message. The name of the fourth message is not limited and can be, for example, instruction information, a reporting instruction, a non-reporting instruction, etc.

[0167] In some embodiments, step S203 may be omitted, and the terminal may report the transmit power information by default.

[0168] Step S204: Terminal 101 generates a first message according to the transmit power information.

[0169] In some embodiments, the first message includes transmit power information of the terminal.

[0170] In some embodiments, the first message is used to report transmit power information, where transmit power may also be referred to as radio frequency power.

[0171] In some embodiments, the name of the first message is not limited, and it can be, for example, a transmission power report, a function report, etc.

[0172] In some embodiments, the transmit power information includes an actual power threshold value and / or a power threshold offset.

[0173] Optionally, the actual power threshold value can be expressed as P limit , the unit of the actual power threshold value is power unit. Optionally, the actual power threshold value may be an upper limit value of the average transmit power within a period of time.

[0174] Optionally, the power threshold offset can be expressed as MPR limit , the unit of the power threshold offset is power unit. In some embodiments, the power threshold offset can be the actual power threshold value P limit Relative to the power level P supported by the terminal powerclass The offset, for example, MPR limit =P powerclass -P limit Among them, the power level P powerclass The unit is power unit, power level P powerclass In some embodiments, the power threshold offset is the actual power threshold value P limit The offset relative to the maximum transmit power Pcmax supported by the terminal, for example, MPR limit =P cmax -P limit The unit of the maximum transmit power Pcmax is power unit, and the maximum transmit power Pcmax is determined by the capability of the terminal.

[0175] In some embodiments, the “offset” may be replaced with the “backward value” or the “advance value”, which is not limited in the present disclosure.

[0176] In some embodiments, the first message is a message specifically used to report transmit power information, and the first message includes transmit power information.

[0177] In some embodiments, the first message is a power headroom report (PHR). Optionally, the transmit power information is a first field of the PHR, and the first field includes at least one bit.

[0178] For example, referring to FIG2B , the first field may be “MPE or MPR” in FIG2B Limit or R" field.

[0179] FIG2B is briefly described here. The first message is a PHR, and the first message may include the following fields:

[0180] P field: The value of the P field can be set to 0 or 1. The value of the P field can be set according to the Maximum Permissible Exposure (MPE) requirement, or the P field is used to indicate whether the power margin has performed power fallback. For the meaning of the P field, please refer to the relevant description in the 3GPP protocol and will not be repeated here. The length of the P field can be 1 bit.

[0181] R field: The R field is a reserved field and can be set to 0 or 1. The length of the R field can be 1 bit.

[0182] PH field: The PH (Power Headroom) field may be used to indicate the power headroom of the terminal device. Optionally, the PH field may be used to indicate the power headroom level of the terminal device. The length of the PH field may be 6 bits.

[0183] MPE or MPR Limit or R field: This field can be MPE, MPR Limit , or R (reserved field) indicates the content. Limit The or R field may be 2 bits long.

[0184] P CMAX,f,c Field: The P CMAX,f,c Indicates the maximum PUSCH transmit power on carrier f of service cell c configured for the terminal device.

[0185] For example, referring to FIG. 2C , the first field may be the MPR in FIG. 2C Limit or R field.

[0186] In some embodiments, the PHR includes a first indication bit, where the first indication bit is used to indicate the content corresponding to the first field in the first frequency band or the second frequency band. Optionally, by setting the first indication bit to a first value, the first field can be correspondingly set to transmit power information, where the transmit power information includes a power threshold offset and / or an actual power threshold value.

[0187] The first indication bit represents the R field in FIG2B or FIG2C , the first frequency band represents FR1, the second frequency band represents FR2, and the first value represents “1”.

[0188] In some embodiments, the PHR includes a second indicator bit, which is used to indicate the content corresponding to the first field in the second frequency band. Optionally, the second indicator bit is set to a first value, and accordingly, the first field is set to the maximum value of the power threshold offset / actual power threshold value and the MPE. For example, if the power threshold offset is greater than the MPE, the second indicator bit may be set to the first value, and the first field may be set to the power threshold offset.

[0189] The second indication bit represents the P field in FIG. 2B or FIG. 2C .

[0190] In some embodiments, the PHR includes a second indicator bit, where the second indicator bit is used to indicate the content corresponding to the first field in the first frequency band. Optionally, the second indicator bit is set to a first value, and accordingly, the first field is set to transmit power information, where the transmit power information includes a power threshold offset and / or an actual power threshold value.

[0191] In some embodiments, assuming that one cell / carrier corresponds to one piece of transmit power information, multiple pieces of transmit power information corresponding to multiple cells / carriers can be reported simultaneously through a single PHR. For example, a PHR includes at least one power headroom field for a cell, and each power headroom field for a cell includes a first field. For each cell, the transmit power information corresponding to the cell is written to the first field of the power headroom field corresponding to the cell. In this way, the power headroom fields corresponding to multiple cells / carriers can be reported through a single PHR.

[0192] Step S205 : Terminal 101 sends a first message to network device 102 .

[0193] In some embodiments, the network device receives a first message.

[0194] In some embodiments, before sending the first message to the network device, the terminal needs to determine whether to start the first function, or needs to determine whether a trigger condition is met.

[0195] For example, the terminal sends a first message to the network device when determining to start the first function and / or determining that the trigger condition is met.

[0196] In some embodiments, the trigger condition includes at least one of the following:

[0197] The terminal detects the presence of a biological object within a preset range;

[0198] The current transmit power of the terminal is greater than a first threshold;

[0199] The uplink duty cycle changes;

[0200] The actual power threshold value is less than the second threshold value;

[0201] The power threshold offset is greater than a third threshold.

[0202] In some embodiments, when a terminal detects a human body approaching, it determines whether the human body is within a preset range of the terminal. If the terminal detects that the human body is within the preset range of the terminal, it may trigger the transmission of a first message to the network device. The preset range is the range within which the electromagnetic radiation of the terminal may have a significant impact on the human body.

[0203] In some embodiments, a biological object refers to a living organism that can be damaged by electromagnetic radiation from a terminal within a preset range of the terminal. Biological objects include but are not limited to humans, animals, and the like.

[0204] In some embodiments, the uplink duty cycle refers to the proportion of uplink transmission time per unit time, that is, the ratio of uplink transmission time to total time. A change in the uplink duty cycle can be understood as a change in the uplink and downlink time slot configuration.

[0205] Step S206: The network device 102 determines whether to perform resource scheduling for the terminal 101 according to the first message.

[0206] In some embodiments, the network device 102 determines the transmit power information of the terminal 101 according to the first message, wherein the transmit power information is used to assist the network device in performing resource scheduling on the terminal. Optionally, resource scheduling includes at least one of the following:

[0207] Duty cycle of the dispatch terminal;

[0208] The scheduling terminal switches the link.

[0209] For example, the network device may determine the transmit power information of the terminal based on the first message, and reduce the uplink duty cycle of the terminal based on the transmit power information. For example, the network device may determine the transmit power information of the terminal based on the first message, and increase the uplink duty cycle of the terminal based on the transmit power information. For example, the network device may determine the transmit power information of the terminal based on the first message, and instruct the terminal to switch links based on the transmit power information.

Optionally, the power limit information may be an actual transmit power limit, which is expressed in power units and can be expressed as P limit Optionally, the power limit information may be a fallback value relative to the power level or maximum transmit power Pcmax, which may be expressed as MPR. limit , where MPR limit =P powerclass -P limit , or, MPR limit =P cmax -P limit .

[0280] In one embodiment, the trigger condition is that the terminal detects a human body approaching, or may further include at least one of the following:

[0281] 1. When the current actual transmit power is greater than a certain threshold. The threshold can be determined by the terminal itself.

[0282] 2. The scheduled uplink duty cycle changes (ie, the uplink and downlink time slot configuration changes). Optionally, the base station notifies the terminal of the change in the uplink duty cycle through RRC signaling.

[0283] 3. P limit Less than a certain threshold.

[0284] 4. MPR limit Greater than a certain threshold.

[0285] In some embodiments, the power limit information may be reported separately.

[0286] In some embodiments, the PHR may be reported together with the PHR. As shown in FIG2B , the R bit in the PHR type may be used to indicate whether the PHR includes the power limit information. For example, when the R bit is set to 1, the MPE or R bit reports the MPRlimit.

[0287] In some embodiments, in the case of FR2 frequency band, if the P position is 1, indicating that MPE needs to be reported, the larger of MPE or MPRLimit can be reported. Alternatively, regardless of whether the P position is 1 or 0, as long as the R position is set to 1, the existing MPE or R position reported is MPR limit .

[0288] In some embodiments, in the FR1 band, the P bit can also be used to indicate whether the MPRlimit is reported, as shown in Figure 2C. This is because in the existing FR1 band, no MPE is reported, and the positions of the Pbit and MPE are reserved.

[0289] In some embodiments, the terminal needs to report to the base station that it has intelligent transmission capabilities, and the base station sends a trigger threshold for power limit information to the terminal. When the terminal detects a human body approaching and the power limit exceeds the threshold sent by the base station, it triggers the reporting of power limit information to the base station.

[0290] In some embodiments, if a power threshold (in units of power) is issued, the trigger condition is that Plimit is less than the threshold; if a power backoff threshold is issued, MPRlimit is required to be greater than the threshold.

[0291] In some embodiments, the base station may control whether to allow the terminal to send the power information through signaling. For example, the terminal is allowed to perform the reporting process only when MPRlimit-Reporting is configured by the base station.

[0292] In some embodiments, the above method is not only suitable for the single-carrier case, but also for the multi-carrier case. In the case of multi-carriers in the same band, the method adopted is similar to that of the single carrier. In the case of multi-carriers between frequency bands, the terminal reports and processes separately according to the carriers of each frequency band, and the base station also processes separately according to different frequency band carriers.

[0293] In some embodiments, the multi-carrier mentioned in the above method not only refers to carrier aggregation technology, but also dual connectivity (DC) technology may include MRDC (Multi-RAT dual connectivity) technology of a multi-access system, such as EN-DC and NE-DC.
