[0041] It should also be understood that all or part of the functions of the network device and the UE in the present application may also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform).

[0042] To avoid harm to the human body caused by electromagnetic radiation devices such as terminal devices, it is necessary to control the electromagnetic radiation intensity of terminal devices. The electromagnetic radiation intensity of terminal devices can be described by the specific absorption rate (SAR) and the maximum permissible emission (MPE). The following takes SAR and MPE as examples for illustration.

[0043] In the frequency band below 6 GHz, SAR is an index parameter for measuring the electromagnetic radiation intensity of terminal devices to the human body. To avoid harm to the human body caused by electromagnetic radiation devices such as mobile phones, the standard has strict index requirements for the SAR value of mobile phone radiation, and terminal devices cannot exceed this limit. The SAR index is the average measurement value of terminal devices over a period of time, and has the characteristics that the higher the transmission power of the terminal device, the higher the SAR value, and the longer the uplink transmission time, the higher the SAR. As shown in Figure 2, when the SRA of the terminal device 220 exceeds the index requirements, it will cause harm to the user 210.

[0044] In the frequency band above 6 GHz, MPE is an index parameter for measuring the electromagnetic radiation intensity of terminal devices to the human body. To avoid harm to the human body caused by electromagnetic radiation devices such as mobile phones, the standard has strict index requirements for the MPE value of mobile phone radiation, and terminal devices cannot exceed this limit. The MPE index is the average measurement value of the power density of terminal devices over a period of time within a certain area, and has the characteristic that the higher the transmission power of the terminal device, the higher the MPE value. As shown in Figure 2, when the MPE of the terminal device 220 exceeds the index requirements, it will cause harm to the user 210.

[0045] To meet the SAR and MPE indices, terminal devices usually can adopt the following two methods.

[0046] The first method is that the terminal device will use, for example, a distance sensor to detect the distance between the terminal device and the human body, and when approaching the human body, it will use the method of power back-off to reduce the transmission power and avoid exceeding the SAR and MPE standards. This method can effectively solve the problem of exceeding the SAR and MPE standards, but the power loss is serious. When the power back-off value is too large, it will also cause the wireless link of the terminal device to fail, thus affecting the communication efficiency.

[0047] Another method, considering reducing the terminal radiation time, introduces the maxUplinkdutycycle (maximum uplink duty cycle) capability for high power levels (such as PC2 26dBm or PC1.5 29dBm, etc.). The maxUplinkdutycycle can represent the maximum uplink duty ratio that the terminal device can withstand without exceeding the SAR or MPE under the maximum transmit power corresponding to the power class (PC) of the terminal device. The terminal device can report to the network at the initial network access the maximum uplink duty ratio it can support when meeting the SAR or MPE within a certain frequency band and within a certain time window length (the window length is determined by the terminal device itself). When the uplink duty ratio scheduled by the network exceeds this capability, the terminal device can adopt the method of power class fallback to reduce the SAR or MPE to ensure human radiation safety. Currently, the terminal reports the maxUplinkdutycycle capability to the base station, and this capability information is static (for example, the maxUplinkdutycycle capability can be written into the terminal device at the factory). At the same time, the base station does not necessarily always schedule the UE according to this capability. When the actual scheduled uplink duty ratio exceeds this capability, power class fallback will occur, thus affecting the communication efficiency.

[0048] As described above, the terminal device can selectively report the maxUplinkdutycycle capability to solve the SAR or MPE problem. However, the drawback of this capability is that the window length and start position for calculating the uplink duty ratio are determined by the terminal device itself. For example, as shown in Figure 3, the time window includes multiple transmission periods such as t1, t2…tn (t1 - tn are all positive numbers), and the terminal device counts the time window by itself during the uplink transmission process. The base station does not know the information of this time window (such as the window start position, window end position, and window length, etc.), which makes it difficult for the base station to consider the maxUplinkdutycycle capability of the terminal device in actual scheduling. It can be seen that the maxUplinkdutycycle capability itself cannot be applied in the actual network for the base station and can only be used to ensure that the terminal device itself meets the SAR or MPE requirements.

[0049] Therefore, both of the above two methods have their respective drawbacks. The first method directly performs power fallback, which limits the transmit power of the terminal device and affects the uplink coverage. For the second method based on the maximum uplink time ratio capability, it is difficult for the base station to know the actual time window length and start position of the terminal device, so it cannot actually apply the maximum uplink time ratio capability in scheduling. Therefore, in these current methods, it is difficult to effectively solve the SAR or MPE problem while taking into account the base station's scheduling of the transmit power and transmit time of the terminal device.

[0050] In addition, the transmissions of the terminal device in the actual network are usually discontinuous, and the transmission power and transmission time of the terminal device may also vary. In the actual network, when the transmission power decreases, the maximum transmission time ratio capacity can become longer, and when the transmission power is higher than 26 dBm, the maximum uplink time ratio capacity will become shorter. For example, as shown in Figure 4, the transmission time lengths (such as T1, T2, T3, and T4, etc., where T1 - T4 are all positive numbers) and transmission power magnitudes (such as P1, P2, P3, and P4, etc., where P1 - P4 are all positive numbers) of the terminal device in each transmission period may be different. At the same time, as mentioned in the foregoing embodiments, the SAR or MPE of the terminal device is related to the transmission power magnitude and transmission time length of the terminal. The greater the transmission power and the longer the transmission time, the more serious the SAR or MPE of the terminal device. Therefore, the transmission power and transmission time length that the terminal device can schedule at a certain moment may not be constant, but related to the transmission power and transmission time in the past period (within the time window). The greater the power already transmitted and the longer the time within the time window, the less the remaining available margin of SAR or MPE.

[0051] However, in the current maxUplinkdutycycle capability reporting mechanism, the maxUplinkdutycycle capability reported by the terminal device corresponds to the maximum transmission power corresponding to the power level of the terminal device. For example, for a terminal device with PC2, its maximum uplink ratio capability is defined according to a transmission power of 26 dBm, and this capability information is reported statically, and it cannot enable the base station to know how much the actual uplink transmission time that the terminal device can schedule at the current moment is.

[0052] To solve one or more of the above technical problems, the present application proposes a communication method and a communication device. The embodiments of the present application will be described in detail with reference to Figures 5 to 9 below.

[0053] Figure 5 is a schematic flowchart of the communication method according to the embodiment of the present application. The method 500 shown in Figure 5 may include step S510, specifically as follows:

[0054] S510, the terminal device sends first information to the network device.

[0055] The first information can be used to determine a first time window and / or the uplink transmission time information within the first time window.

[0056] The uplink transmission time information may be related to the transmission power and uplink transmission time in the past period (within the second time window). Optionally, the uplink transmission time information may be determined according to the uplink transmission time and transmission power within the second time window, and the second time window may be the time window before the current moment.

[0057] For example, before S510, method 500 may further include step S520, which is specifically as follows:

[0058] S520. The terminal device determines uplink transmission time information according to the uplink transmission time and transmission power within a second time window, where the second time window is a time window before the current moment. In this way, the uplink transmission time information can be dynamically determined, enabling the network device to know in real time the available uplink transmission time information of the current terminal device, so that the network device can schedule the terminal device based on the uplink transmission time information. For example, as shown in FIGS. 7 and 8, the terminal device can determine the uplink transmission time information according to the uplink transmission times T1, T2, T3, and T4 and the transmission powers P1, P2, P3, and P4 before the current moment, and T1 - T4 and P1 - P4 are all positive numbers.

[0059] Optionally, the uplink transmission time information may represent the uplink transmission time that the terminal device can support at the current moment. For example, as shown in FIG. 6, the terminal device can report the uplink transmission time information to the network device at time t (t is a positive number). Optionally, the greater the power and the longer the time already transmitted within the second time window, the less the margin of available (i.e., remaining available) SAR or MPE within the first time window (i.e., the less the uplink transmission time that can be supported at the current moment).

[0060] Optionally, the uplink transmission time information may include the maximum available uplink transmission time length and / or the maximum available uplink transmission time ratio within the first time window.

[0061] The maximum available uplink transmission time length may represent the length of the maximum uplink transmission time that can be supported when SAR or MPE is satisfied within the first time window. For example, the maximum available uplink transmission time length may be in units such as microseconds (us), milliseconds (ms), seconds (s), symbols (symbol), sub - frames (sub - frame), or frames (frame). Optionally, the maximum available uplink transmission time length may be selected from a predefined time length. For example, 16 bits (bit) may be used to represent the value of the maximum available uplink transmission time length.

[0062] The maximum available uplink transmission time ratio may represent the ratio of the maximum uplink time that can be supported when SAR or MPE is satisfied within the first time window.

[0063] Optionally, the uplink transmission time information may correspond to first power information. The first power information may be implicitly indicated. For example, the first power information may be a preset power value. Or, the first power information may also be explicitly indicated. For example, the first information may include the first power information.

[0064] Optionally, the first power information may be any of the following: the maximum transmit power corresponding to the power level of the terminal device, the transmit power of the terminal device at the current moment, and a preset transmit power.

[0065] FIG. 7 is introduced by taking the maximum available uplink transmission time length as an example. For example, as shown in FIG. 7, the uplink transmission time information 1 reported by the terminal device may be the maximum available uplink transmission time length, and the maximum available uplink transmission time length may correspond to a transmit power of 26 dBm. The maximum available uplink transmission time length may represent the maximum time length during which the terminal device can transmit at a power of 26 dBm before the UE reports the uplink transmission time information 2.

[0066] It should be noted that if the actual transmit power of the scheduled terminal device is lower than 26 dBm, the actual transmit time of the terminal device may exceed the maximum available uplink transmission time length, but these network devices do not know this. Therefore, regardless of the actual transmit power of the terminal device, the network device may schedule the terminal device with the maximum available uplink transmission time length.

[0067] When the cumulative time length of the network device scheduling the terminal device to transmit exceeds the maximum available uplink transmission time length, the terminal device may adopt methods such as power backoff or power level backoff to ensure that it meets the SAR or MPE index requirements.

[0068] FIG. 8 is introduced by taking the maximum available uplink transmission time ratio as an example. For example, as shown in FIG. 8, the uplink transmission time information 1 reported by the terminal device is the maximum available uplink transmission time ratio, and the maximum available uplink transmission time ratio may correspond to a transmit power of 26 dBm. The maximum available uplink transmission time ratio may represent the maximum time ratio during which the terminal device can transmit at a power of 26 dBm before the UE reports the uplink transmission time information 2 (or, it may also be other time window lengths, such as a time window starting from the moment when the terminal device reports the uplink transmission time information 1 and with a length of n subframes, where n is a positive number).

[0069] When the cumulative time ratio of the network device scheduling the terminal device to transmit exceeds the maximum available uplink transmission time ratio, the terminal device may adopt methods such as power backoff or power level backoff to ensure that it meets the SAR or MPE index requirements.

[0070] It should be noted that the terminal device may include two or more transmission channels, and the first power information may be the total transmission power corresponding to all the transmission channels of the terminal device. For example, for a terminal device with a power level of PC2, if it has two transmission channels, where one transmission channel supports an output power of 23 dBm and the other transmission channel supports an output power of 26 dBm, then the total transmission power corresponding to all the transmission channels of the terminal device is 23 + 26 = 27.8 dBm. Therefore, the first power information corresponding to the uplink transmission time information of the terminal device may be this total transmission power (i.e., 27.8 dBm).

[0071] The first time window may be implicitly indicated. For example, the first time window may be a preset time window. Alternatively, the first time window may also be explicitly indicated. For example, the first information may include the start time and length of the first time window.

[0072] Optionally, the start time of the first time window may be any of the following: the time when the terminal device sends the first information, the time when the network device receives the first information.

[0073] It should be noted that the terminal device may calculate the signal transmission time between the terminal device and the network device based on the timestamp in the downlink signal sent by the network device and the time when the downlink signal arrives at the terminal device, and thus may determine the time when the network device receives the first information based on the signal transmission time; or the terminal device may also calculate the time when the network device receives the first information based on the timing advance (TA) between the terminal device and the network device.

[0074] Optionally, the length of the first time window may be the interval length between two consecutive transmissions of the first information by the terminal device, that is, the interval length between two consecutive reports of the uplink transmission time information by the terminal device. For example, as shown in FIGS. 7 and 8, the length of the first time window may be the interval length between the time t1 when the terminal device reports the uplink transmission time information 1 and the time t2 when the terminal device reports the uplink transmission time information 2, where t1 and t2 are positive numbers.

[0075] Alternatively, the length of the first time window may also be other lengths indicated by the terminal device (for example, a time window starting from the time when the terminal device reports the uplink transmission time information and having a length of n subframes, etc.).

[0076] Optionally, in the case where the first information only includes the first time window (excluding the uplink transmission time information within the first time window), the uplink transmission time information may be the time information reported by the terminal device to the network during initial network access in the prior art (such as maxUplinkdutycycle (maximum uplink time ratio)).

[0077] In some embodiments, the terminal device may periodically report first information to the network device, that is, report it once every certain period of time, to implement dynamic update of its uplink transmission time information. For example, the terminal device may periodically send the first information to the network device.

[0078] Optionally, the reporting period for the terminal device to report the first information may be predefined, such as reporting once every default 10 ms or 10 subframes; or it may be configured by the network device, such as the network device configuring the terminal device to report once every 10 ms or 10 subframes.

[0079] In some embodiments, the terminal device may also report the first information to the network device in an event-triggered manner. For example, when a preset event is triggered, the terminal device may send the first information to the network device.

[0080] Optionally, the preset event may include at least one of the following: the available uplink transmission time of the terminal device meets a preset threshold value, an event that triggers the terminal device to report power headroom (PHR). The available uplink transmission time of the terminal device may be the remaining available uplink transmission time of the terminal device.

[0081] Optionally, the existing PHR reporting may be periodic reporting or event-triggered reporting, etc. These events that trigger the terminal device to report PHR can all trigger the terminal device to report uplink transmission time information at the same time. Optionally, the preset event may be consistent with each value (such as the reporting period, each threshold value in the triggering event, etc.) in the event that triggers the terminal device to report PHR, or may take different values.

[0082] In some embodiments, the terminal device may send the first information to the network device through any of the following signaling: radio resource control (RRC) signaling, medium access control control element (MAC CE), power headroom (PHR) reporting signaling.

[0083] It should be noted that PHR is a MAC CE for the terminal device to report the available power headroom to the network, and can carry information such as the maximum available transmission power information and power headroom information of the terminal device. PHR may be periodic reporting configured by the network, or reporting based on event triggering (such as when the transmission power headroom of the terminal device changes beyond a certain threshold, etc.). PHR information is an important reference for the network device to control the transmission power of the terminal device.

[0084] In some embodiments, a network device-configurable timer may be further introduced to enable the network device to control whether to allow or disallow the terminal device to report uplink transmission time information. For example, the terminal device may be configured with a first timer and / or a second timer. Among them, when the first timer is activated, the terminal device may be disallowed to send a first piece of information to the network device, and when the second timer is activated, the terminal device may be allowed to send the first piece of information to the network device. Optionally, only one of these two timers (the first timer and the second timer) may be configured, or both may be configured, or neither may be configured.

[0085] Method 500 may further include step S530, which is specifically as follows:

[0086] S530, the network device schedules the terminal device according to the first piece of information.

[0087] In the embodiments of the present application, the first piece of information is used to determine the first time window and / or the uplink transmission time information within the first time window. The terminal device sending the first piece of information to the network device helps the network device perform uplink scheduling on the terminal device based on the first piece of information, which can avoid the terminal device from performing power backoff and thus improve the communication efficiency of the terminal device.

[0088] The method embodiments of the present application have been described in detail above in conjunction with FIGS. 1 to 8. Next, the device embodiments of the present application will be described in detail in conjunction with FIGS. 9 to 11.

[0089] FIG. 9 is a schematic structural diagram of a communication device provided by an embodiment of the present application. As shown in FIG. 9, the device 900 includes a sending unit 910, which is specifically as follows:

[0090] The sending unit 910 is configured to send a first piece of information to the network device, where the first piece of information is used to determine the first time window and / or the uplink transmission time information within the first time window.
