In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

The embodiments of the present application are described in conjunction with a terminal device and a network device, where: a terminal device may also be referred to as a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, or a User Equipment, etc. The terminal device may be a Station (ST) in a WLAN, and may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, and a next generation communication system, for example, a terminal device in an NR Network or a terminal device in a future-evolution Public Land Mobile Network (PLMN) Network, and the like.

By way of example and not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable equipment can also be called wearable intelligent equipment, is the general term of equipment that uses wearable technique to carry out intelligent design, develop can dress to daily wearing, such as glasses, gloves, wrist-watch, dress and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device has full functions and large size, and can realize complete or partial functions without depending on a smart phone, for example: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets for physical sign monitoring, smart jewelry and the like.

The network device may be a device for communicating with a mobile device, and the network device may be an Access Point (AP) in a WLAN, a Base Station (BTS) in GSM or CDMA, a Base Station (NodeB, NB) in WCDMA, an evolved Node B (eNB, eNodeB) in LTE, a relay Station or an Access Point, or a network device or a Base Station (gNB) in a vehicle-mounted device, a wearable device, and an NR network, or a network device in a PLMN network for future evolution.

In this embodiment, a network device provides a service for a cell, and a terminal device communicates with the network device through a transmission resource (for example, a frequency domain resource or a spectrum resource) used by the cell, where the cell may be a cell corresponding to the network device (for example, a base station), and the cell may belong to a macro base station or a base station corresponding to a Small cell (Small cell), where the Small cell may include: urban cells (Metro cells), micro cells (Micro cells), pico cells (Pico cells), femto cells (Femto cells), and the like, and the small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-rate data transmission services.

In order to meet the SAR index, a terminal usually adopts a distance sensor or the like to detect the distance between the terminal and a human body, and a power back-off method is performed when the terminal is close to the human body to reduce the transmission power and avoid the SAR exceeding standard. The method effectively solves the problem of SAR standard exceeding. However, with the recent tightening of the SAR test method (the test is no longer a terminal placement posture but becomes a method that all mobile phone faces and sides need to be close to the human body and the SAR is tested), the solution is increasingly unable to guarantee the SAR radiation of the terminal in various placement postures. A more general solution is needed.

The occurrence of high power terminals (26 dBm) in LTE causes the SAR overproof problem to attract more and more attention, and compared with a common terminal (23 dBm), the transmission power of the high power terminal (26 dBm) is higher, and the SAR value is also higher. In order to solve the problem that the SAR value of the LTE high-power terminal exceeds the standard, a method for limiting the ratio of Uplink and downlink time slots is provided, that is, a static ratio of Uplink and downlink time slots is generally adopted in the existing LTE network, as shown in table 1 below, by excluding Uplink-downlink configuration (Uplink-downlink configuration) 0 and 6 whose Uplink ratio exceeds 50%, the Uplink transmission time of the terminal is limited to be less than 50%, and the problem of high SAR value brought by the high-power terminal is eliminated to a certain extent.

TABLE 1 LTE static uplink and downlink timeslot ratios

In table 1, D denotes a downlink subframe, S denotes a special subframe, and U denotes an uplink subframe.

NR was also introduced for high power terminals and standardization also attempted to solve the SAR over-limit problem in a manner similar to LTE, but it was difficult to achieve agreement. The reason is that the uplink and downlink of LTE have only 7 configurations and are static configurations, but NR has more than 60 configurations, as shown in table 2 below, and each configuration has a flexible symbol therein that can be configured as uplink or downlink. This makes the calculation of the uplink proportion in each uplink and downlink configuration very difficult. In order to solve the problem that the SAR exceeds the standard, the terminal capability of a maximum uplink time slot ratio (maxultyclie) is introduced, namely the terminal reports the maximum uplink time slot ratio supported by the network in a certain frequency band to the network, and when the uplink time slot ratio scheduled by the network equipment exceeds the capability, the terminal reduces the SAR value by adopting a power back-off mode. The scheme can solve the problem that the SAR emitted by an independent site (standby) terminal in an NR frequency band exceeds the standard.

Table 2 nr uplink and downlink symbol configuration

In table 2, D denotes a downlink symbol, X denotes a flexible symbol, and U denotes an uplink symbol.

For an NR terminal (e.g., a sub-6GHz high-power terminal and/or a millimeter-wave terminal), only one maximum uplink timeslot proportion capability is currently reported, where the proportion corresponds to a scenario where the terminal transmits at maximum power, but when the terminal transmission power is lower than the maximum transmission power, the terminal may schedule a higher uplink proportion, but is still limited by the uplink proportion capability according to the current working mechanism.

For example, when the terminal is at 26dBm, the uplink timeslot occupation ratio corresponding to the SAR not exceeding the standard is 50%, the terminal reports 50% of the maximum uplink occupation ratio capacity that can be scheduled, when the power is 23dBm, the terminal is also limited by the uplink occupation ratio capacity, and in practice, when the terminal is at 23dBm, the uplink occupation ratio corresponding to the SAR not exceeding the standard can reach 90%. This means that 40% of the uplink share of the terminal cannot be scheduled, and thus the uplink throughput is severely limited.

Therefore, how to ensure that the terminal equipment always meets the SAR standard and simultaneously utilize the uplink ratio of the terminal equipment to the maximum is a problem to be solved.

The technical solution of the present application designed to address the above technical problems is described in detail below.

Fig. 2 is a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application, and as shown in fig. 2, the method 200 may include the following:

s210, the terminal equipment determines a first corresponding relation, wherein the first corresponding relation is a corresponding relation between the transmitting power and the maximum uplink ratio, and each maximum uplink ratio is the maximum uplink ratio which ensures that the SAR does not exceed the standard under the transmitting power corresponding to each maximum uplink ratio;

s220, the terminal device sends first information to a network device, where the first information includes the first corresponding relationship, and the first information is used for the network device to schedule uplink transmission time domain resources of the terminal device based on the first corresponding relationship;

s230, the network device receives the first information.

It should be noted that the uplink transmission time domain resource may be an uplink transmission time slot.

It should be understood that in the embodiments of the present application, the transmission power may also be referred to as a transmission power.

Optionally, the embodiment of the present application is applied to NR communication.

Optionally, the terminal device is a high power (sub-6 GHz) terminal device and/or a millimeter wave terminal device.

Optionally, in this embodiment of the present application, the terminal device sends the first information to the network device when accessing the network. That is, the terminal device may determine the first correspondence in advance, and send the first information to the network device when accessing the network.

Accordingly, the network device receives the first information sent by the terminal device when accessing the network.

Optionally, in this embodiment of the present application, the transmission power in the first corresponding relationship is transmission power for a high-power terminal device, or the transmission power in the first corresponding relationship is peak transmission power for a millimeter-wave terminal device.

For example, the transmission power in the first corresponding relationship is the transmission power for the high-power terminal device, and in this case, the first corresponding relationship may be as shown in table 3 below.

TABLE 3

Launch power (dBm)	26	25	24	23	…
						Maximum uplink ratio	x ₁ ％	x ₂ ％	x ₃ ％	x ₄ ％	…

For another example, the transmission power in the first corresponding relationship is the peak transmission power for the millimeter wave terminal device, and in this case, the first corresponding relationship may be as shown in table 4 below.

TABLE 4

Peak transmission power (dBm)	43	42	41	40	…
						Maximum uplink ratio	x ₁ ％	x ₂ ％	x ₃ ％	x ₄ ％	…

It should be noted that, the description of The transmission Power of The millimeter wave terminal generally adopts an antenna test (OTA) parameter, such as Total Radiated Power (TRP), peak Power in a certain direction, and The like. The above Pcmax in the millimeter wave Power control is described by using Peak Effective Radiated Power (Peak EIRP) as a parameter.

Optionally, the network device may schedule the uplink transmission time domain resource of the terminal device with reference to the first corresponding relationship.

Optionally, in this embodiment of the present application, the terminal device sends second information to the network device, where the second information is used to indicate an actual transmission power of the terminal device, and the first information is specifically used for the network device to schedule the uplink transmission time domain resource of the terminal device based on the actual transmission power and the first corresponding relationship.

That is, after receiving the second information, the network device may schedule the uplink transmission time domain resource of the terminal device according to the actual transmission power and the first corresponding relationship.

It should be noted that, in order to obtain the actual transmission Power of the terminal device, the network device needs to report a Power Headroom (PH) to solve the problem. Currently, the reporting of the PH is performed as shown in fig. 3, that is, the terminal reports the power headroom PH, and simultaneously reports the theoretical maximum transmission power (Pcmax) to the network device. Thus, the network device can know that the theoretical transmission power of the terminal device is: pcmax-PH. However, when the terminal uses the power backoff value (P-MPR), the actual transmit power of the terminal device may deviate from this calculation. Therefore, the power back-off value needs to be reported to the network at the same time.

Optionally, the second information includes a Power Headroom (PH), a power backoff value, and a theoretical maximum transmit power (Pcmax) of the terminal device, wherein the actual transmit power = the theoretical maximum transmit power-the power headroom-the power backoff value. For example, the terminal device may send the second information to the network device in a PH reporting manner as shown in fig. 4.

Optionally, the second information includes a Power Headroom (PH) and a maximum transmit power (Pcmax, u) available to the terminal device, wherein the maximum transmit power (Pcmax, u) = a theoretical maximum transmit power (Pcmax) -a power backoff value of the terminal device, and the actual transmit power = a maximum transmit power available to the terminal device-the power headroom. For example, the terminal device may send the second information to the network device in a PH reporting manner as shown in fig. 5.

In fig. 3, 4, and 5, the Power Headroom (PH) is mainly for Type 1 (Type 1) and the Primary Cell (PCell).

Optionally, in this embodiment of the present application, the terminal device periodically sends the second information to the network device.

Accordingly, the network device periodically receives the second information sent by the terminal device.

It should be noted that a period in which the terminal device sends the second information is a PH reporting period.

Optionally, the period for reporting the second information by the terminal device may be preconfigured, or may be configured or indicated by the network device.

Therefore, the network device can obtain the actual transmitting power of the terminal device in real time, and determine the maximum uplink ratio which can be scheduled by the terminal device based on the first corresponding relation, thereby realizing the dynamic adjustment of the uplink ratio.

Optionally, the period of scheduling, by the network device, the uplink transmission time domain resource of the terminal device may be an integral multiple of the PH reporting period.

That is, the network device periodically schedules the uplink transmission time domain resource of the terminal device according to the actual transmission power and the first corresponding relationship, wherein the scheduling period is an integral multiple of the receiving period.

Therefore, in the embodiment of the application, the high-power terminal equipment and/or millimeter wave terminal equipment SAR in NR communication are/is prevented from exceeding the standard, and the excessive limitation on the uplink transmission time slot is avoided. The network equipment can acquire the actual transmitting power of the terminal equipment in real time, and determines the schedulable maximum uplink ratio capacity of the current terminal equipment by combining the first corresponding relation (the corresponding relation between the transmitting power and the maximum uplink ratio) reported by the terminal equipment, so that the terminal equipment is scheduled as required.

Fig. 6 is a schematic flow chart of a wireless communication method 300 according to an embodiment of the present application, and as shown in fig. 6, the method 300 may include the following:

s310, the terminal equipment determines the maximum uplink ratio according to at least one of the actual transmitting power, the uplink service requirement and the position in the network;

s320, the terminal device sends first information to a network device, where the first information includes the maximum uplink occupancy ratio, and the first information is used for the network device to schedule an uplink transmission time domain resource of the terminal device according to the maximum uplink occupancy ratio;

s330, the network equipment receives the first information;

s340, the network device schedules the uplink time domain resource of the terminal device according to the maximum uplink occupied ratio.

It should be noted that the terminal device actively reports the maximum uplink ratio capacity in real time. That is, the terminal device may determine to apply for more or less uplink timeslot resources to the network device according to at least one of the actual transmission power, the uplink service requirement, and the location in the network, which is closer to the actual requirement of the terminal device, and saves unnecessary uplink timeslot allocation. For example, when the terminal device is located at the edge of a cell, it is more important for the terminal device to maintain high transmission power, otherwise, the problem that the network cannot be accessed due to insufficient power is caused. But when the terminal equipment is in the center of the cell, the terminal equipment can use low transmission power to replace more uplink time slot resources. Therefore, the dynamic uplink time slot application initiated by the terminal equipment is more effective.

Optionally, the embodiments of the present application are applied to NR communication.

Optionally, as a first embodiment, the first information further includes a Power Headroom (PH) and a theoretical maximum transmission power (Pcmax) of the terminal device.

That is, as shown in fig. 7, the maximum uplink duty cycle (maxuplinkdytycycle) may be reported along with the PH.

Specifically, in the first embodiment, the maximum uplink duty cycle (maxuplinkdtycycle) reporting information is added in the PH. If the maximum uplink occupation ratio is vacant, the maximum uplink occupation ratio reported at the latest moment is used. At present, the PH belongs to periodic reporting, and the network device can periodically know the maximum uplink ratio which can be currently scheduled by the terminal device. In addition, event-triggered PH reporting may be newly introduced, for example, when the transmission power of the terminal device changes greatly or there is a bursty data transmission service, the terminal device may report PH information to the network device (mainly aiming at obtaining the maximum uplink ratio).

Optionally, in the first embodiment, if the first information includes a domain corresponding to the maximum uplink proportion, and the maximum uplink proportion is not configured or vacant, the network device is defaulted to schedule the uplink transmission time domain resource of the terminal device according to the maximum uplink proportion received last time.

Correspondingly, if the first information includes a domain corresponding to the maximum uplink occupation ratio, and the maximum uplink occupation ratio is not configured or vacant, the network device schedules the uplink transmission time domain resource of the terminal device according to the maximum uplink occupation ratio received last time.

Specifically, in the first embodiment, the terminal device sends the first information to the network device when the power headroom needs to be reported.

Optionally, in the first embodiment, the terminal device periodically sends the first information to the network device.

Correspondingly, the network device periodically receives the first information sent by the terminal device.

Optionally, in the first embodiment, in the case that the change value of the transmission power is greater than the first threshold, and/or in the case that there is bursty data to be transmitted, the terminal device sends the first information to the network device.

Correspondingly, the network device receives the first information sent by the terminal device when the change value of the transmission power of the terminal device is larger than the first threshold value and/or when the terminal device has bursty data to be transmitted.

Optionally, as a second embodiment, the first information further includes capability control information. Specifically, when the body temperature of the terminal device is greater than a second threshold, the first information is sent to the network device.

Note that the capability control information may also be referred to as terminal assistance information (UEAssistanceInformation).

Optionally, the capability control information is used for the network device to reduce the transmission power for the terminal device and/or close part of the transmission channel for the terminal device.

Optionally, in the second embodiment, the maximum uplink occupancy ratio is valid within the first time window.

Optionally, in the second embodiment, after exceeding the first time window, the first information is used for the network device to schedule the uplink transmission time domain resource of the terminal device according to the default or the maximum uplink occupation ratio received last time.

Correspondingly, if the first time window is exceeded, the network device schedules the uplink transmission time domain resource of the terminal device according to the default or the maximum uplink occupation ratio received last time.

Optionally, the first time window may be preconfigured or may be configured or indicated by the network device.

Optionally, in the second embodiment, if the first information includes a domain corresponding to the maximum uplink proportion, and the maximum uplink proportion is not configured or vacant, the network device is defaulted to schedule the uplink transmission time domain resource of the terminal device according to the maximum uplink proportion received last time.

That is, in the second embodiment, the network device may obtain the maximum uplink ratio currently schedulable to the terminal by reading the maximum uplink ratio (maxuplinkdytycycle) in the UEAssistanceInformation message. The network device uses the most recently received maximum uplink fraction value unless it receives a new maximum uplink fraction value. Alternatively, the network device uses the default maximum uplink ratio value unless it receives a new maximum uplink ratio value, and the new maximum uplink ratio value is valid only for a certain time window, and the default maximum uplink ratio value is reused after the time exceeds the time window.

Optionally, in this embodiment of the present application, the terminal device may further determine a first corresponding relationship, where the first corresponding relationship is a corresponding relationship between transmission power and a maximum uplink ratio, and each maximum uplink ratio is a maximum uplink ratio at which the terminal device guarantees that the SAR does not exceed the standard under the transmission power corresponding to each maximum uplink ratio. Further, the terminal device determines the maximum uplink occupation ratio according to at least one of actual transmission power, uplink service requirement, location in the network, and the first corresponding relationship.

Optionally, the transmission power in the first corresponding relationship is transmission power for a high-power terminal device, or the transmission power in the first corresponding relationship is peak transmission power for a millimeter wave terminal device.

For example, the transmission power in the first corresponding relationship is the transmission power for the high-power terminal device, and in this case, the first corresponding relationship may be as shown in table 3 above.

For another example, the transmission power in the first corresponding relationship is a peak transmission power for the millimeter wave terminal device, and in this case, the first corresponding relationship may be as shown in table 4 above.

Optionally, the first corresponding relationship may be reported to the network device, or may not be reported to the network device.

Therefore, in the embodiment of the present application, the terminal device actively reports the maximum uplink ratio capability in real time. That is, the terminal device may determine to apply for more or less uplink timeslot resources to the network device according to at least one of the actual transmission power, the uplink service requirement, and the location in the network, which is closer to the actual requirement of the terminal device, and saves unnecessary uplink timeslot allocation. For example, when the terminal device is located at the edge of a cell, it is more important for the terminal device to maintain high transmission power, otherwise, the problem that the network cannot be accessed due to insufficient power is caused. But when the terminal equipment is in the center of the cell, the terminal equipment can use low transmission power to replace more uplink time slot resources. Therefore, the dynamic uplink time slot application initiated by the terminal equipment is more effective.
