In an embodiment, the communication system 100 may further include other network entities such as a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

Taking the communication system 100 shown in fig. 1 as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function, and the network device 110 and the terminal device 120 may be the specific devices described above and are not described herein again; the communication device may also include other devices in the communication system 100, such as other network entities, for example, a network controller, a mobility management entity, and the like, which is not limited in this embodiment.
Fig. 2 is a schematic flow chart of a communication method 200 according to an embodiment of the present application, wherein the method may be performed by a terminal device. The method 200 includes at least some of the following.
At 210, the terminal device obtains a maximum uplink share ratio, where the maximum uplink share ratio is a maximum value of at least one uplink share ratio that causes a power density not to exceed a standard when the terminal device is directed to a user in a first direction and transmits at a first transmit power.
In 220, the terminal device determines the actual transmit power according to the maximum uplink occupancy ratio.
In the embodiment of the present application, that the power density is not exceeded may be understood as that the power density of the terminal device is less than or equal to the power density index. Wherein the power density index may be a value specified by a standard. For example, the power density index may be 10W/m 2. In one embodiment, the power density indicator may be preset on the terminal device.
In general, the power density is related to the transmission power of the terminal device, the beam used for uplink transmission, and the uplink ratio, and the higher the transmission power of the terminal device, the narrower the beam used for uplink transmission, and the higher the uplink ratio, the higher the power density.
In the embodiment of the present application, the uplink occupancy may be understood as a proportion of time domain resources used for uplink transmission in one time unit. In one embodiment, the time unit may be a subframe, a slot, a time domain symbol, or a Short Transmission Timing Interval (sTTI). For example, there are 10 slots in a subframe, if there are 6 slots in the 10 slots that can be used for uplink transmission and 4 slots that can be used for downlink transmission, the uplink proportion is 60%.
In this embodiment of the present application, the uplink occupancy may be scheduled by the network device, or autonomously determined by the terminal device. That is, the uplink transmission of the terminal device may be the uplink transmission scheduled by the network device, or the uplink transmission autonomously initiated by the terminal device.
It should be understood that the name of the uplink ratio is not limited in the embodiments of the present application, that is, the uplink ratio may also be referred to as another name, for example, the uplink ratio may also be referred to as an uplink transmission time ratio or an uplink time ratio.
In the embodiment of the present application, the terminal device may support transmission on a millimeter wave frequency band. At this time, the terminal device may be referred to as a millimeter wave terminal device or by other names, which is not specifically limited in this embodiment of the present application.
It should be noted that the propagation loss of the millimeter wave terminal device is relatively large, and in order to overcome the large propagation loss, the millimeter wave terminal device may generally adopt a narrow beam to concentrate energy in a direction facing the network device, so that the millimeter wave terminal device may easily form relatively strong electromagnetic radiation energy in a certain direction.
In this embodiment, the first direction may be a direction in which a beam with the strongest transmission power is located among beams in which all terminal devices perform uplink communication, and the first transmission power may be the transmission power of the beam with the strongest transmission power. At this time, the first transmission power may be referred to as a radiation peak power. Or
The first direction may be a direction in which an actual beam actually used for uplink communication by the terminal device is located, and the first power is a conducted power of the actual beam when the power amplifier is adjusted to the maximum value. It should be understood that the actual beam may not have the maximum transmit power among all beams used for uplink transmission by the terminal device.
In one embodiment, the maximum uplink occupancy may be different for different frequency bands. The maximum uplink occupancy may be different for different terminal devices, for example, the maximum uplink occupancy of terminal device 1 may be 90%, and the maximum uplink occupancy of terminal device 2 may be 85%. The maximum uplink occupancy of different beams for uplink communication may also be different for the same terminal device. For example, the maximum uplink occupancy of beam 1 for uplink transmission by terminal device 1 may be 95%, and the maximum uplink occupancy of beam 2 for uplink transmission by terminal device 1 may be 89%.
In an embodiment, the maximum uplink proportion may be preset on the terminal device, so that the terminal device may obtain the maximum uplink proportion.
In this embodiment, the method 200 may further include: the terminal equipment sends first information to the network equipment, wherein the first information comprises the maximum uplink occupation ratio. Accordingly, the network device may receive the first information. Illustratively, the terminal device may send the first information to the network device upon accessing the network.
When the network equipment acquires the maximum uplink ratio and determines that the actual uplink ratio of the terminal equipment exceeds the maximum uplink ratio, the network equipment can reduce the ratio of time domain resources which are scheduled for uplink transmission of the terminal equipment; or, the network device may also directly reduce the modulation coding and the transmission power of the terminal device, so as to reduce the actual uplink occupation ratio.
In this embodiment, the network device may determine that the actual uplink proportion of the terminal device exceeds the maximum uplink proportion in a variety of ways, which is exemplified below.
In an example, the terminal device may count the actual uplink proportion, and determine the magnitude of the actual uplink proportion and the maximum uplink proportion, and if the actual uplink proportion exceeds the maximum uplink proportion, the terminal device may send third information to the network device, where the third information is used to notify the network device that the actual uplink proportion exceeds the maximum uplink proportion.
In one embodiment, the third information may inform the network device that the actual uplink share exceeds the maximum uplink share by at least one bit.
Illustratively, the third information may inform the network device that the actual uplink occupancy exceeds the maximum uplink occupancy by a bit "1" or a bit "0".
As another example, the number of bits of the third information may be multiple, and if the multiple bits are the same, it indicates that the actual uplink ratio exceeds the maximum uplink ratio. For example, "000" indicates that the actual uplink share exceeds the maximum uplink share.
In one embodiment, the third information may inform the network device that the actual uplink share exceeds the maximum uplink share by the first parameter. It should be noted that, in the embodiment of the present application, the first parameter is not specifically limited, and any parameter that can indicate that the actual uplink ratio exceeds the maximum uplink ratio is included in the protection scope of the present application.
In another example, the network device may autonomously determine an actual uplink occupancy ratio of the terminal device, and compare the actual uplink occupancy ratio with the obtained maximum uplink occupancy ratio, so as to determine whether the actual uplink occupancy ratio of the terminal device exceeds the maximum uplink occupancy ratio.
In one implementation, the determining, by the terminal device, the actual transmit power according to the maximum uplink occupied ratio may include: the terminal equipment determines the actual uplink ratio in the uplink ratio window, and further determines the actual transmitting power based on the actual uplink ratio and the maximum uplink ratio.
In one embodiment, the window length of the uplink proportion may be determined by the terminal device, and the window length may be any value, for example, the window length of the uplink proportion may be 10ms, 1s, and so on.
In the embodiment of the application, the terminal device may determine the actual uplink proportion under any circumstances, or may compare the initial transmission power at the current time with the transmission power threshold, and if the initial transmission power is greater than the transmission power threshold, the terminal device determines the actual uplink proportion again.
In this embodiment, the transmission power threshold may be a transmission power at which the terminal device is aligned to the user in the first direction and the uplink occupancy is 100%, for example, when transmitting in the full uplink timeslot, the power density is not exceeded.
In one embodiment, the transmission power threshold may be preset on the terminal device, so that the terminal device may obtain the transmission power threshold.
In one embodiment, the transmission power thresholds of different terminal devices may be different, and the transmission power thresholds of different beams used for uplink communication of the same terminal device may be different.
It should be appreciated that, as can be seen from the above definition of the transmit power threshold, when the initial transmit power of the terminal device does not exceed the transmit power threshold, there is no risk that the power density at the current time is exceeded. Therefore, under the condition that the initial transmitting power of the terminal equipment exceeds the transmitting power threshold value, the actual uplink ratio is determined, and the actual transmitting power is determined based on the actual uplink ratio and the maximum uplink ratio, so that the power consumption of the terminal equipment can be reduced.
Specifically, the terminal device may detect whether or not it is operating close to the user by a built-in distance sensor, touch sensor, gyroscope, or the like. When the terminal device detects that the terminal device approaches to the user, the terminal device starts to detect the initial transmitting power at the current moment. If the initial transmission power is less than or equal to the transmission power threshold value, the terminal device may determine the initial transmission power as the actual transmission power; if the initial transmission power is greater than the transmission power threshold value, the terminal device may determine the actual uplink ratio and compare the actual uplink ratio with the maximum uplink ratio.
If the actual uplink proportion is less than or equal to the maximum uplink proportion, the terminal device may determine the first transmission power as the actual available maximum transmission power. Illustratively, the terminal device may determine the first transmit power as the actual transmit power.
As a possible embodiment, if the actual uplink ratio is greater than the maximum uplink ratio, in this case, the terminal device has a risk that the power density exceeds the standard, and therefore, the terminal device may reduce the initial transmission power to obtain the actual transmission power.
In this embodiment, the maximum value of the initial transmission power that the terminal device can reduce may be a difference between the first transmission power and a transmission power threshold value. In the embodiment of the present application, the maximum value of the initial transmission power that the terminal device can reduce may be referred to as a maximum power back-off value.
After the terminal device reduces the initial transmission power to obtain a second transmission power, if the second transmission power is still greater than the transmission power threshold, the terminal device may continue to compare the actual uplink ratio in the uplink ratio window at the current time with the maximum uplink ratio, and if the actual uplink ratio in the uplink ratio window at the current time is less than or equal to the maximum uplink ratio, the terminal device may determine the first transmission power as the actual transmission power.
In an embodiment, if the actual uplink ratio in the uplink ratio window at the current time is less than or equal to the maximum uplink ratio, the terminal device may determine the first transmission power as the actual transmission power, which may include: if the actual uplink occupancy is less than or equal to the maximum uplink occupancy within the preset time period, the terminal device may determine the first transmission power as the actual transmission power.
The length of the preset time period is not limited in the embodiment of the present application, for example, the preset time period may be 20 ms. Therefore, frequent adjustment of the second transmitting power can be avoided, and the performance of the terminal equipment can be improved.
In this embodiment, the reducing, by the terminal device, the initial transmission power to obtain the actual transmission power may include: the terminal equipment determines the actual transmission loss of the uplink transmission, compares the actual transmission loss with the maximum transmission loss of the uplink transmission, and if the actual transmission loss is greater than the maximum transmission loss, the terminal equipment can adjust the actual uplink ratio and then determine the actual transmitting power based on the adjusted actual uplink ratio.
Let the actual propagation loss be PL, the transmit power of the downlink signal be E, and the downlink reference signal receive strength be R, then PL is E-R.
The maximum propagation loss may be a difference between the second transmit power and the network device receive sensitivity. For example, let MCL be the maximum propagation loss, P be the second transmit power, and B be the base station receive sensitivity, then MCL be P-B. Wherein, the receiving sensitivity of the network device can be understood as the lowest signal strength required by the network device.
In one embodiment, the terminal device may acquire the network device receiving sensitivity according to a protocol specification, or the terminal device may receive information including the network device receiving sensitivity sent by the network device, so that the terminal may acquire the network device receiving sensitivity.
As an example, in this embodiment of the application, the adjusting, by the terminal device, the actual uplink ratio may include: the terminal equipment and the network equipment negotiate to adjust the actual uplink occupation ratio.
Specifically, the terminal device may send notification information to the network device, where the notification information may be used to notify the network device to reduce the actual uplink occupancy ratio. And after the network equipment receives the notification information, reducing the actual uplink occupation ratio.
As another example, the adjusting, by the terminal device, the actual uplink proportion may include: the terminal equipment autonomously adjusts the actual uplink occupation ratio and does not perform uplink transmission in the time unit capable of performing uplink transmission.
Illustratively, there are 10 slots in a subframe, which are slot 0 and slot 1 … …, and slot 9, where slot 0 and slot 1 … are used for uplink transmission, and slot 9 is used for downlink transmission, and the actual uplink proportion is 90%. The terminal device transmits the uplink data to the network device on the time slot 0, the time slot 1 …, the time slot 5, the time slot …, the time slot 8 are not used for transmitting the uplink data, so that the terminal device can reduce the actual uplink occupancy from 90% to 50%.
In one embodiment, the maximum value of the reduced actual uplink share ratio may be the maximum uplink share ratio.
In this embodiment of the present application, the determining, by the terminal device, the actual transmit power based on the adjusted actual uplink ratio may include: the terminal equipment compares the third transmission power with the transmission power threshold value. If the third transmission power is lower than the transmission power threshold value, the terminal device may determine the third transmission power as the actual transmission power.
And the third transmitting power is the transmitting power corresponding to the adjusted actual uplink occupation ratio.
Specifically, the second transmission power may be increased to obtain the third transmission power while the terminal decreases the actual uplink duty ratio. When the third transmission power can ensure that the connection of the uplink and the downlink is continuous and is lower than the transmission power threshold value, the terminal device may send information including the actual uplink occupation ratio reduction stop to the network device, or automatically stop reducing the actual uplink occupation ratio.
It should be understood that, in the embodiments of the present application, the terms "first", "second" and "third" are merely used to distinguish different objects, and do not limit the scope of the embodiments of the present application.
It should also be appreciated that, after the terminal device reduces the initial transmit power to the second transmit power, the uplink and downlink may not be maintained, for example, the second transmit power is 20dBm, and the actual propagation loss of the uplink transmission is 23dBm, at which time the uplink and downlink may not be maintained. According to the technical scheme, the actual propagation loss of uplink transmission is compared with the maximum propagation loss, and the transmitting power of the terminal equipment is improved by reducing the actual uplink proportion under the condition that the actual propagation loss is larger than the maximum propagation loss, so that the power density is not overproof while the continuous connection of an uplink and a downlink is ensured.
As another possible embodiment, if the actual uplink ratio is greater than the maximum uplink ratio, the terminal device may decrease the actual uplink ratio to obtain the actual transmission power.
At the moment, the terminal equipment can ensure that the power density does not exceed the standard while the uplink coverage is not reduced.
In this embodiment, the method 200 may further include: and the terminal equipment sends second information to the network equipment, wherein the second information comprises a transmission power threshold value and/or a maximum power back-off value. Accordingly, the network device may obtain the transmission power threshold value and/or the maximum power back-off value.
If the second information includes the transmission power threshold, after the network device obtains the transmission power threshold, the time for starting to count the actual uplink ratio of the terminal device may be determined based on the transmission power threshold.
If the second information includes the maximum power back-off value, the network device may determine whether to take a certain action based on the maximum power back-off value to avoid that the uplink and the downlink cannot be maintained. For example, if the maximum power back-off value is higher, the terminal device may reduce the initial transmission power to a greater extent, and at this time, in order to maintain the uplink and downlink, the network device may instruct the terminal device to switch to another network or to switch to another beam of the current network. For example, if the current network is an NR network and the beam used for the terminal device to perform uplink communication is beam 1, the network device may instruct the terminal device to switch to an LTE network or instruct the terminal device to switch to beam 2 of the NR network.
It should be understood that the term "and/or" herein is merely one type of association relationship that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone.
In the embodiment of the present application, since the uplink proportion has a correlation with the power density, the correlation may be that the higher the uplink proportion is, the higher the power density is under certain other conditions. In addition, the power density is correlated with the transmission power of the terminal equipment, and the transmission power of the terminal equipment determined based on the uplink occupation ratio is finally reflected on the power density. Therefore, the transmitting power of the terminal equipment is determined based on the maximum uplink ratio, so that the power density of the terminal equipment can be ensured not to exceed the standard, and the power density of the terminal equipment can be effectively prevented from exceeding the standard.
Fig. 3 is a schematic flow chart of a communication method 300 according to an embodiment of the present application, where the method may be performed by a terminal device. The method 300 includes at least some of the following.
In 310, the terminal device sends first information to the network device, where the first information includes a maximum uplink duty ratio, and the maximum uplink duty ratio is a maximum value of at least one uplink duty ratio that causes a power density not to exceed a limit when the terminal device is directed to a user in a first direction and transmits at a first transmission power.
Accordingly, the network device may receive the first information. Illustratively, the terminal device may send the first information to the network device upon accessing the network.
The terminal device may support transmission in the millimeter wave band.
In an embodiment, the first direction is a direction in which a beam with the strongest transmission power is located among all beams used for the terminal device to perform uplink communication, and the first transmission power is the transmission power of the beam with the strongest transmission power. Or
The first direction is a direction in which an actual beam actually used for the terminal device to perform uplink communication is located, and the first power is conducted power of the actual beam when the power amplifier is adjusted to the maximum value.
When the network equipment acquires the maximum uplink ratio and determines that the actual uplink ratio of the terminal equipment exceeds the maximum uplink ratio, the network equipment can reduce the ratio of time domain resources which are scheduled for uplink transmission of the terminal equipment; or, the network device may also directly reduce the modulation coding and the transmission power of the terminal device, so as to reduce the actual uplink occupation ratio.
In this embodiment, the network device may determine that the actual uplink proportion of the terminal device exceeds the maximum uplink proportion in a variety of ways, which is exemplified below.
In an example, the terminal device may count the actual uplink proportion, and determine the magnitude of the actual uplink proportion and the maximum uplink proportion, and if the actual uplink proportion exceeds the maximum uplink proportion, the terminal device may send third information to the network device, where the third information is used to notify the network device that the actual uplink proportion exceeds the maximum uplink proportion.
In one embodiment, the third information may inform the network device that the actual uplink share exceeds the maximum uplink share by at least one bit.
Illustratively, the third information may inform the network device that the actual uplink occupancy exceeds the maximum uplink occupancy by a bit "1" or a bit "0".
As another example, the number of bits of the third information may be multiple, and if the multiple bits are the same, it indicates that the actual uplink ratio exceeds the maximum uplink ratio. For example, "000" indicates that the actual uplink share exceeds the maximum uplink share.
In one embodiment, the third information may inform the network device that the actual uplink share exceeds the maximum uplink share by the first parameter. It should be noted that, in the embodiment of the present application, the first parameter is not specifically limited, and any parameter that can indicate that the actual uplink ratio exceeds the maximum uplink ratio is included in the protection scope of the present application.

In an embodiment of the present application, the method 300 may further include: the terminal equipment sends second information to the network equipment, wherein the second information comprises a transmitting power threshold value and/or a maximum value of the initial transmitting power which can be reduced;
the threshold value of the transmitting power is the transmitting power which makes the power density not exceed the standard when the terminal equipment aims at the user in the first direction and the uplink ratio is 100%, and the maximum value of the initial transmitting power which can be reduced by the terminal equipment is the difference value between the first transmitting power and the threshold value of the transmitting power.
If the second information includes the transmission power threshold, after the network device obtains the transmission power threshold, the time for starting counting the actual uplink ratio of the terminal device may be determined based on the transmission power threshold.
If the second information includes the maximum power back-off value, the network device may determine whether to take a certain action based on the maximum power back-off value to avoid that the uplink and the downlink cannot be maintained. For example, if the maximum power back-off value is higher, the terminal device may reduce the initial transmission power to a greater extent, and at this time, in order to maintain the uplink and downlink, the network device may instruct the terminal device to switch to another network or to switch to another beam of the current network. For example, if the current network is an NR network and the beam used for the terminal device to perform uplink communication is beam 1, the network device may instruct the terminal device to switch to an LTE network or instruct the terminal device to switch to beam 2 of the NR network.
In an embodiment of the present application, the method 300 may further include: and the terminal equipment sends notification information to the network equipment, wherein the notification information is used for notifying the network equipment to reduce the actual uplink ratio in the uplink ratio window.
