Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
As described in the background art, the conventional method has a problem of unreliable communication, and the inventor finds that the problem is caused by the fact that, after the SAR value adjustment mechanism is triggered, the terminal device limits the uplink transmission power within a safety value, which is an allowable power value obtained by a certification laboratory after the strictest test is performed, for both FDD and TDD communication modes, in the conventional method for meeting the SAR regulatory standard. Taking 5G TDD communication as an example, the timeslot configuration is relatively flexible in TDD communication, and the base station may configure the uplink timeslot of the terminal device in a range from 1% to 100%. In this application scenario, the certification laboratory will take 100% as the uplink timeslot for testing, and obtain the corresponding transmission power when the SAR value meets the relevant specifications. By writing the transmission power as a safety value into the terminal device, the transmission power of the terminal device can be limited in a fixed scene.
Referring to fig. 1, fig. 1 shows a curve of the change of the transmission power with time when the SAR value is adjusted by the conventional method, where P0 is the requested power of the base station, P1 is the initial transmission power, P2 is the safety value, i.e., the transmission power value meeting the SAR index requirement obtained by the strictest standard test, and t1 is the trigger time of the SAR value adjustment mechanism. Curve 110 is the base station requested power versus time curve and curve 120 is the terminal device transmit power versus time curve. As can be seen from fig. 1, in the case that the SAR value adjustment mechanism is not triggered, the terminal device transmits an uplink signal at the power of P1; after the SAR value adjustment mechanism is triggered, no matter how much the uplink timeslot occupation ratio is, the terminal device will transmit the uplink signal strictly according to the power of P2, so as to ensure that the SAR value meets the relevant requirements.
Therefore, in the conventional technology, after the SAR value adjustment mechanism is triggered, no matter whether the uplink timeslot configured by the terminal device is 20%, 50%, or 100%, the terminal device always limits the transmission power of the terminal device according to the 100% timeslot configuration requirement, so that the communication capability of the terminal device is limited to an excessively low power level. Therefore, in the case of weak signal coverage, when the terminal device performs critical signal feedback or event reporting, the problem of communication delay caused by incomplete communication or repeated transmission is easy to occur, and the problem is more prominent particularly in a network game scene.
In addition, the conventional method may also be: and the base station determines the target transmitting power and issues a control message based on the target transmitting power, so that the terminal equipment can directly acquire the target transmitting power from the control message and adjust the transmitting power to the target transmitting power so as to reduce the SAR value of the terminal equipment. However, since the terminal device has a characteristic of strong mobility, a plurality of different base stations can provide communication services for the terminal device for a certain period of time, and if the SAR value of the terminal device is constantly kept within a predetermined index requirement, the plurality of base stations in the communication system need to be updated, which results in a large amount of work.
Based on this, it is necessary to provide a wireless communication method, apparatus, terminal device and storage medium capable of dynamically adjusting transmission power so that the SAR value of the terminal device meets the index requirement. Meanwhile, the wireless communication method can be applied to the terminal equipment, and the SAR value can be adjusted through the terminal equipment, so that signal interaction with a base station can be reduced, and the adjustment efficiency is improved.
The wireless communication method provided by the application can be applied to the application environment shown in fig. 2. Wherein the terminal device 202 is communicatively connected to the network device 204 and communicates with the network device 204 via wireless signals, and further is capable of cellular communication with the network device 204. During communication, the network device 204 configures the uplink timeslot proportion for the terminal device 202, so that the terminal device 202 can communicate with the network device 204 according to the configured uplink timeslot proportion. The terminal device 202 will transmit the uplink signal according to the corresponding transmission power and the configured uplink timeslot proportion. The terminal device 202 may be, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices, and the network device 204 may be, but is not limited to, a base station and a router, and for convenience of description, the network device 204 in the following embodiments is explained by taking the base station as an example.
In one embodiment, as shown in fig. 3, a wireless communication method is provided, which is described by taking the method as an example applied to the terminal device in fig. 2, and includes the following steps:
step 310, obtaining the current uplink timeslot occupation ratio of the terminal device.
The current uplink timeslot occupation ratio refers to the proportion of uplink timeslot resources allocated to the terminal device by the base station at the current time to total timeslot resources. Taking TDD communication as an example, the terminal device communicates with the base station through communication frames, each communication frame may be divided into a plurality of subframes, each subframe may be divided into a plurality of time segments, and each time segment is a time slot. In the TDD communication mode, uplink and downlink communications are performed using the same frequency band, and the time occupied by the uplink and downlink communications in the frequency band can be adjusted as required, so that part or all of the time slots of a communication frame can be configured for uplink communications (the time slot configured for uplink communications is an uplink time slot), and/or part or all of the time slots of a communication frame can be configured for downlink communications (the time slot configured for downlink communications is a downlink time slot), and at this time, the uplink time slot ratio can be the ratio of the uplink time slot to the total time slots of the communication frame.
In the present application, the terminal device may obtain the current uplink timeslot proportion of the device according to the configuration message issued by the base station, and may also obtain the current uplink timeslot proportion of the device through real-time statistics.
Step 320, determining the target transmitting power of the terminal equipment according to the current uplink time slot ratio, and adjusting the current transmitting power of the terminal equipment to the target transmitting power; the target transmission power is the maximum transmission power which can enable the SAR value of the terminal equipment to be smaller than or equal to the SAR threshold value under the condition that the uplink time slot occupation ratio of the terminal equipment is configured to be the current uplink time slot occupation ratio.
The current transmission power refers to a power value adopted by the terminal device to transmit the communication signal at the current time, that is, the signal power of the communication signal transmitted by the terminal device at the current time. The target transmission power refers to the maximum transmission power which can be used on the premise that the SAR value of the terminal equipment can meet the SAR index requirement when the terminal equipment transmits signals according to the current uplink time slot ratio. The specific value of the target transmission power may vary with the change of the current uplink timeslot proportion, for example, when the current uplink timeslot proportion is 10%, the target transmission power may be power a, and when the current uplink timeslot proportion is 100%, the target transmission power may be power B, where power a is not equal to power B.
The target transmission power may be continuously changed along with the change of the current uplink timeslot proportion, that is, the target transmission power may be a continuous curve with the current uplink timeslot proportion as an argument. In this case, for two current uplink timeslot occupation ratios with different values, no matter whether the difference between the two current uplink timeslot occupation ratios is large enough, the target transmission powers respectively corresponding to the two current uplink timeslot occupation ratios may not be equal. For example, the target transmit power corresponding to the case where the current uplink timeslot proportion is 1% may be power C, and the target transmit power corresponding to the case where the current uplink timeslot proportion is 2% may be power (C + 1). Therefore, the problem of large error caused by 'level system' adjustment can be solved, the accuracy of power adjustment is improved, and the communication performance and the communication reliability are improved as much as possible on the premise that the SAR value of the terminal equipment can meet the SAR index requirement.
Specifically, considering that when the uplink slot occupancy of the terminal device decreases while the transmission power of the terminal device remains unchanged, the average power of the terminal device in one communication frame decreases proportionally, and the SAR value of the terminal device is associated with the average power, so that when the transmission power is unchanged, the SAR value decreases with the decrease of the uplink slot occupancy. The lower the uplink timeslot proportion, the lower the average power in a communication frame, and the lower the SAR value of the terminal device. Therefore, if the SAR value of the terminal device remains unchanged, when the configured uplink timeslot occupation ratio is reduced, the transmission power of the terminal device is increased, in other words, even if the transmission power of the terminal device is increased under the condition that the uplink timeslot occupation ratio is reduced, the SAR value of the terminal device can meet the related index requirement. Therefore, the corresponding target transmitting power can be determined according to the current uplink time slot ratio, and when the terminal equipment transmits the communication signal by adopting the target transmitting power, the SAR value index requirement and the communication performance can be considered.
It is understood that although the terminal device determines the target transmission power based on the current uplink timeslot proportion, the terminal device itself does not request the base station to adjust the current uplink timeslot proportion of the terminal device in order to reduce the SAR value. Because the current uplink time slot ratio is generally determined by the base station according to the data transmission quantity, the geographical position of the terminal equipment, the signal strength of the terminal equipment and other factors, the terminal equipment can perform more effective and reliable data communication under the current uplink time slot ratio so as to ensure the normal operation of the communication. Therefore, if the current uplink timeslot proportion is adjusted for the purpose of reducing the SAR value of the terminal device, the adjusted uplink timeslot proportion may have a problem that the current communication requirement of the terminal device cannot be met, resulting in a decrease in communication performance. In order to avoid the problem, the current transmitting power of the terminal equipment is adjusted according to the current uplink time slot ratio configured by the base station, and the current uplink time slot ratio can be kept unchanged before and after the transmitting power is adjusted, so that the adverse effect on the communication performance can be reduced as much as possible on the premise of meeting the SAR index, and the reliability of communication can be improved. It should be noted that the above description is only for the application scenario of SAR value adjustment, and if the terminal device actively requests the base station to adjust its uplink timeslot proportion based on the consideration of communication quality or communication rate during the adjustment process.
In the wireless communication method, the current uplink time slot ratio of the terminal equipment is obtained, the target transmitting power of the terminal equipment is determined according to the current uplink time slot ratio, and the current transmitting power of the terminal equipment is adjusted to the target transmitting power. The target transmission power is the maximum transmission power which can enable the SAR value of the terminal equipment to be less than or equal to the SAR threshold under the condition that the uplink time slot occupation ratio of the terminal equipment is configured as the current uplink time slot occupation ratio. Therefore, under the scene of SAR value adjustment, the current transmitting power of the terminal equipment can be different along with the difference of the current uplink time slot ratio, so that the current transmitting power can be dynamically adjusted and reasonable power limitation can be carried out, on the premise that the terminal equipment meets the SAR index requirement, the current transmitting power of the terminal equipment is improved, the communication reliability is improved, and the user experience is improved.
In one embodiment, as shown in fig. 4, the step of determining the target transmit power of the terminal device according to the current uplink timeslot proportion includes:
step 410, acquiring a transmission power limit value of the terminal equipment; the transmission power limit value is the transmission power which can enable the SAR value of the terminal equipment to be smaller than or equal to the SAR threshold value under the condition that the uplink time slot occupation ratio of the terminal equipment is configured to be the maximum uplink time slot occupation ratio.
The transmission power limit value refers to an allowable power value tested under the most strict test condition, i.e., the safety value described in the above embodiment. In other words, the transmit power limit value may be the transmit power used to make the SAR value of the terminal device less than or equal to the SAR threshold when the uplink timeslot proportion of the terminal device is configured as the maximum uplink timeslot proportion (e.g., 100%), that is, if the terminal device transmits the communication signal according to the maximum uplink timeslot proportion and the transmit power limit value, the SAR value of the terminal device will meet the SAR specification requirement.
Specifically, the transmission power limit value may be stored in the terminal device in advance, so that the terminal device can obtain the transmission power limit value by reading the memory of the terminal device. Alternatively, the terminal device may obtain the transmit power limit value through network communication, real-time calculation, and the like, which is not specifically limited in the present application.
And step 420, calculating target transmitting power according to the transmitting power limit value and the current uplink time slot ratio.
Specifically, the target transmit power may be calculated according to the transmit power limit value and the current uplink timeslot proportion, and the calculation mode may be determined according to the type of the terminal device, the communication frequency band supported by the terminal device, and the antenna parameter (such as the antenna position, the antenna signal, and the antenna transmit power) of each antenna on the terminal device, which is not limited in this application. In one embodiment, the terminal device may calculate the target transmit power based on the following expression to improve the accuracy of the target transmit power:
Figure BDA0002986557610000101
in the formula, P target Is the target transmit power in dbm; PL is the transmit power limit in dbm; and T is the current uplink time slot percentage and the unit is%.
In this embodiment, since the transmit power limit value is generally a power value obtained through a strict test, the target transmit power is calculated according to the transmit power limit value and the current uplink timeslot proportion, which not only can improve the accuracy of power adjustment, but also can improve the communication performance and communication reliability as much as possible on the premise of ensuring that the SAR value of the terminal device can meet the SAR index requirement.
In one embodiment, as shown in fig. 5, the step of obtaining the transmit power limit value comprises:
step 510, acquiring a current communication scene, a current communication frequency band and an antenna position of a current communication antenna of the terminal device;
step 520, determining a transmit power limit value according to the current communication scenario, the current communication frequency band and the antenna position.
The current communication scene refers to an application scene of the terminal device at the current moment, including but not limited to a call scene, an internet surfing scene, and the like, and the SAR indexes (that is, SAR thresholds) can be distinguished in different communication scenes. The current communication frequency band refers to a communication frequency band used by the terminal device at the current time. Since the same terminal device may include multiple communication antennas, when transmitting a communication signal, each communication antenna or each transmitting antenna is not necessarily in a state of working at the same time, and in order to improve power adjustment accuracy, it is necessary to acquire an antenna (i.e., a current communication antenna) used when the terminal device transmits a current communication signal.
Specifically, the transmit power limit value is associated with a current communication scenario, a current communication band, and an antenna position of a current communication antenna, which may each be a factor affecting the transmit power limit value. For example, the transmit power limit values for different communication bands and the same antenna position are different for the same communication scenario. Therefore, the transmission power limit value can be determined according to the current communication scene, the current communication frequency band and the antenna position. In one embodiment, the terminal device may pre-establish and/or store a configuration table, where the configuration table is used to reflect a corresponding relationship between a communication frequency band, an uplink time slot ratio, an antenna position, and a transmit power limit value, and perform table lookup by using a current communication scenario, a current communication frequency band, and an antenna position of a current communication antenna, so as to quickly obtain a corresponding transmit power limit value, thereby improving adjustment efficiency.
In this embodiment, the transmit power limit value is determined according to the current communication scenario, the current communication frequency band, the antenna position, and other backoff scenarios, so that the accuracy of the transmit power limit value can be improved, and the communication performance can be further improved.
In one embodiment, the step of obtaining the current uplink timeslot proportion includes: and acquiring the current communication system of the terminal equipment, and determining the current uplink time slot ratio according to the current communication system. The terminal equipment can determine the current uplink time slot ratio in different modes for different communication modes, so that the accuracy of the uplink time slot ratio is improved, the accuracy of target transmitting power is improved, and the communication reliability and the communication performance are further improved.
In an embodiment, in a case that the current communication system is a 2G communication system, a 3G communication system, or a 4G communication system, referring to fig. 6, the step of determining the current uplink timeslot proportion includes:
step 610, acquiring a current proportion configuration type of the terminal equipment and a corresponding relation between the proportion configuration type and an uplink time slot ratio;
and step 620, determining the uplink time slot ratio corresponding to the current ratio configuration type in the corresponding relationship as the current uplink time slot ratio.
The 2G communication system may be any communication system in 2G communication, the 3G communication system may be any communication system in 3G communication, and the 4G communication system may be any communication system in 4G communication.
Specifically, in 2G communication, 3G communication and 4G communication, the uplink timeslot proportion is relatively fixed, that is, the uplink timeslot proportion is generally taken from several fixed values and is associated with a proportional configuration type. Therefore, after the current ratio configuration type is obtained, table look-up can be performed through the current ratio configuration type, that is, the corresponding relationship between the ratio configuration type and the uplink time slot ratio is inquired, so that the uplink time slot ratio (that is, the current uplink time slot ratio) corresponding to the current ratio configuration type is obtained. In one embodiment, the terminal device may obtain the current proportional configuration type from an event delivered by the network.
In an embodiment, in a case that the current communication system is the 5G communication system, referring to fig. 7, the step of determining the current uplink timeslot proportion includes:
step 710, counting the number of uplink time slots and the total number of the time slots in the same communication frame in real time; the communication frame is used by the terminal equipment and the network equipment in communication;
and step 720, determining the ratio of the uplink time slot number to the total time slot number as the current uplink time slot ratio.
Wherein, the 5G communication system can be any communication system in 5G communication,
specifically, in 5G communication, the slot adjustment is flexible and arbitrary, and the uplink slot occupancy can be flexibly adjusted from 1% to 100%, without being limited to a few fixed values. Therefore, in order to accurately obtain the current uplink time slot ratio under the 5G communication system, the number of the uplink time slots and the total number of the time slots in the same communication frame can be counted in real time, and the ratio of the number of the uplink time slots and the total number of the time slots is determined as the current uplink time slot ratio.
In one embodiment, the wireless communication method further comprises the steps of:
under the condition of receiving the registration message, acquiring the current uplink time slot ratio, and updating the terminal configuration parameters according to the current uplink time slot ratio and the registration message; the terminal configuration parameters comprise uplink time slot proportion and a communication frequency band;
under the condition of receiving the RRC configuration message, judging whether an uplink time slot reconfiguration event, a communication frequency band switching event and/or a communication channel switching event occur or not according to the RRC configuration message and the terminal configuration parameters; and if so, acquiring the current uplink time slot ratio, and updating the terminal configuration parameters according to the current uplink time slot ratio and the RRC configuration message.
Specifically, the terminal device may monitor the registration event, and after the registration event is monitored, the terminal device may obtain, from the registration message, communication parameters such as a communication frequency band, a communication channel, and/or a current uplink time slot ratio configured for the terminal device by the base station, and update the terminal configuration parameters according to the current uplink time slot ratio and the registration message. In addition, the terminal device can also monitor the reconfiguration event and the switching event, and when receiving the RRC configuration message, the terminal device can acquire communication parameters, such as a target communication frequency band, a target communication channel and/or a target uplink time slot ratio, carried in the message from the RRC configuration message, and can determine whether an uplink time slot reconfiguration event, a communication frequency band switching event and/or a communication channel switching event occurs by comparing the acquired communication parameters with the terminal configuration parameters. Specifically, when the target communication frequency band is different from the communication frequency band in the terminal configuration parameters, it can be determined that a communication frequency band switching event occurs; when the target communication channel is different from the communication channel in the terminal configuration parameters, the occurrence of communication channel switching time can be confirmed; and when the target uplink time slot occupation ratio is different from the uplink time slot occupation ratio in the terminal configuration parameters, confirming that an uplink time slot reconfiguration event occurs. And when an uplink time slot reconfiguration event, a communication frequency band switching event and/or a communication channel switching event occur, updating the latest configuration parameters of the terminal equipment into the configuration parameters of the terminal. Therefore, dynamic monitoring of the uplink time slot ratio can be achieved, the current transmitting power is recalculated by utilizing the uplink time slot ratio of the dynamic monitoring network, and therefore the terminal equipment can be guaranteed to enter the transmitting power capable of improving the terminal equipment under reasonable power limitation, the communication performance is improved, and the user experience is improved.
To facilitate understanding of the aspects of the present application, a specific example will be described below. The terminal device can monitor the triggering event (such as a registration event, an uplink timeslot reconfiguration event, a communication frequency band switching event, and a communication channel switching event) through the monitoring thread and update the current uplink timeslot proportion. The terminal device may also determine to update the current transmit power by the main thread. As shown in fig. 8, fig. 8 is a schematic flow chart illustrating execution of snooping, which specifically includes the following steps:
step 810, starting up the terminal equipment;
step 820, the terminal device starts a monitoring thread;
step 830, the terminal device continuously monitors whether the registration event occurs in the device, if yes, the process jumps to step 840, and if not, the monitoring is finished when the terminal device releases the RRC connection state or the base station releases the terminal device;
step 840, the terminal equipment obtains the current uplink time slot ratio;
step 850, the terminal device updates the current uplink time slot ratio of the terminal device and reports the current uplink time slot ratio, the communication frequency band and the communication channel to the main thread;
step 860, the terminal device continuously monitors whether the uplink timeslot reconfiguration event, the communication frequency band switching event and the communication channel switching event occur in the device, if yes, the process goes to step 840, and if not, the monitoring is finished when the terminal device releases the RRC connection state or the base station releases the terminal device.
When initiating a request for connecting a certain network to a base station, a terminal device can trigger a behavior of acquiring an event, thereby realizing monitoring of the event. After monitoring the registration event, the terminal device may read the configuration information of the uplink shared channel and obtain the configuration information of the uplink timeslot, and update and report the current uplink timeslot proportion. After the terminal equipment is connected with the network, namely the terminal equipment is in an RRC (radio resource control) connection state, an uplink time slot reconfiguration event, a communication frequency band switching event and a communication channel switching event can be monitored through a monitoring thread, and when any reconfiguration/switching event is monitored, an uplink time slot detection process is initiated to acquire the current uplink time slot proportion. And when the current uplink time slot ratio and the communication frequency band and/or the communication channel are/is changed, the monitoring thread actively reports and updates the uplink time slot ratio. Therefore, the uplink time slot ratio can be detected by identifying the current network configuration information of the terminal equipment, and the terminal equipment can dynamically detect the current uplink time slot ratio in real time under the triggering of the uplink time slot reconfiguration event, the communication frequency band switching event and the communication channel switching event, so that the transmitting power can be determined and updated according to the current uplink time slot ratio. To boost the transmission power and optimize the communication performance of the terminal device.
Referring to fig. 9, fig. 9 is a schematic diagram illustrating a flow of updating the transmission power by the main thread, which specifically includes the following steps:
step 910, starting a monitoring thread;
step 920, when receiving the reported update time slot configuration event, looking up a configuration table through the current communication frequency band, the current communication scene and the antenna position of the current communication antenna; the configuration table is used for reflecting the corresponding relation among a communication frequency range, a communication scene, an antenna position of a communication antenna and a transmission power limiting value;
step 930, updating the transmit power according to the table lookup result.
Specifically, after testing in a certified laboratory, SAR power limits (i.e., transmit power limit values) corresponding to various adjustment parameters (the adjustment parameters include a communication frequency band, an antenna position, and a communication scenario) can be obtained under different uplink timeslot occupation ratios of the 4G and 5G TDD frequency bands. The terminal device stores the table corresponding relation (namely the configuration table) of the communication frequency band, the communication scene, the antenna position of the communication antenna and the transmitting power limit value, when the main thread receives the update time slot configuration event, the configuration table is searched, so that the corresponding transmitting power limit value can be obtained, and the current transmitting power of the terminal device is adjusted according to the transmitting power limit value.
Referring to fig. 10, fig. 10 shows a curve of the change of the transmission power with time when the SAR value is adjusted by using the scheme of the present application, where P3 is the requested power of the base station, P4 is the initial transmission power, P5 is the target transmission power corresponding to the current uplink timeslot percentage of 50%, P6 is the target transmission power corresponding to the current uplink timeslot percentage of 100%, and t2 is the trigger time of the SAR value adjustment mechanism. Curve 130 is a curve of the requested power of the base station changing with time, curve 140 is a curve of the transmission power changing with time when the ratio of the current uplink time slot is 50%, and curve 150 is a curve of the transmission power changing with time when the ratio of the current uplink time slot is 100%. As can be seen from fig. 10, compared with backing up power according to 100% of the uplink timeslot proportion, when the uplink timeslot proportion of the terminal device is 50%, its transmission power can be increased by 3dbm compared with the previous one. When the uplink time slot of the terminal equipment is 25%, the transmission power can be improved by 6dbm compared with the prior art. According to the field test experience of the 5G network, most of the network is unobstructed and configured, and the uplink time slots are less than 50%. Therefore, the method can greatly improve the transmitting power of the equipment, thereby improving the communication performance of the equipment.
