Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, fig. 1 is a diagram of an application environment of a terminal, where the application environment includes a terminal UE100 and an eNB base station 200, and a connection between the UE and the eNB may be established in 4GEPS through RRC connection in the prior art. When the terminal UE100 communicates with the eNB base station 200, for example, in uplink or downlink, if the data throughput speed is high, the terminal UE may generate heat.
Aiming at the problem of terminal heating, the software processing adopts a Thermal Mitigation mode, and higher heat can be generated at higher downlink data speed. Because the higher the downlink data speed, the higher the operation speed of the Baseband Processor (Baseband chip/modem chip) is, the more the operation amount is, the more the power is consumed, and therefore, the higher the heat is generated.
Referring to fig. 2 and 3, which are the power consumption and the total temperature change of each hardware module of Sub-6 and mmWave spectra respectively at different downlink speeds, it can be understood from the power distribution information provided by the chip vendor that the module mainly consuming power (generating heat) is a Baseband Processor (BP, or Modem CPU, Modem chip), and this is the power consumption (generated heat) generated by processing downlink data operation, and the higher the downlink speed of the Modem CPU, the higher the generated heat. Therefore, the temperature change curve is divided into a plurality of temperature intervals, CQI/RI reporting is limited to quickly modulate the downlink speed, and the purposes of heating and slowing are achieved.
Taking a temperature rising curve in a temperature change curve as an example, as shown in fig. 4, fig. 4 is a graph of a downlink speed and a temperature rise, an X axis represents time, and a Y axis represents temperature, it can be known that, in the same communication system, if a terminal UE can quickly fine-tune a speed of downlink data, the temperature can be lowered before the temperature reaches a SCG (Secondary Cell Group) that needs to be interrupted, and a change of a downlink data throughput is relatively gradual, taking 5G as an example.

Fig. 6 is a schematic flowchart of a method for regulating a terminal temperature according to an embodiment of the present application, where as shown in fig. 6, the method includes:
101: and acquiring a temperature change curve of the terminal, wherein the temperature change curve at least comprises two adjacent temperature intervals.
Generally, the downstream speed of the terminal causes a temperature change of the terminal. Including hardware module temperatures such as CPU temperature.
The temperature change of the terminal can be preliminarily counted to obtain a temperature change curve of the terminal, which can include a temperature rise curve and a temperature drop curve, as shown in fig. 7, the temperature rise curve or the temperature drop curve is divided into 4 temperature intervals, which are respectively a T1 interval, a T2 interval, a T3 interval and a T4 interval, and certainly, the temperature change curve is not limited to 4 temperature intervals, but is at least 2.
102: and detecting the real-time temperature value of the terminal.
103: and determining the temperature interval of the real-time temperature value according to the temperature change curve.
Specifically, the temperature value of the terminal is monitored in real time, and the temperature interval where the real-time temperature value is located is determined according to the temperature change curve.
The real-time temperature value of the detection terminal can be detected in a mode that a temperature sensor is arranged inside the terminal, the real-time temperature value of the terminal is monitored in real time through an internal temperature sensor, and the internal temperature sensor sends the real-time temperature value to a controller of the terminal.
The terminal stores a temperature change curve, compares the received real-time temperature value sent by the internal temperature sensor with the temperature change curve to determine that the current temperature value is in a specific temperature interval of the temperature change curve, and specifically determines that the real-time temperature value is in the first interval when the real-time temperature value is not less than the minimum temperature value of the first interval and not more than the maximum temperature value of the first interval; and when the real-time temperature value is not less than the minimum temperature value of the second interval and not more than the maximum temperature value of the second interval, determining that the real-time temperature value is located in the second interval.
For example, the real-time temperature value is determined to be in the first interval T1, or in the second interval T2, and so on.
104: and acquiring the maximum value of the Channel Quality Indicator (CQI) and the maximum value of the Rank Indicator (RI) corresponding to the temperature interval.
A CQI (Channel Quality Indicator) for reflecting the Channel Quality of the downlink PDSCH. The channel quality of PDSCH is represented by 0 to 15. 0 indicates the worst channel quality and 15 indicates the best channel quality.
RI (rank indication) is used to indicate the number of valid data layers of the downlink PDSCH and to tell the eNB the number of CWs (Code Word codewords) that the UE can now support. That is, RI is 1, 1 CW. RI >1, 2 CW.
For example, the temperature interval includes a first interval T1 and a second interval T2, taking a temperature rise curve as an example, acquiring a maximum value of a channel quality indicator CQI and a maximum value of a rank indicator RI corresponding to the temperature interval may include:
and if the real-time temperature value is located in the first interval, acquiring the maximum value of the Channel Quality Indicator (CQI) and the maximum value of the Rank Indicator (RI) corresponding to the first interval.
And 105, limiting the maximum CQI value reported by the terminal to the maximum CQI value, and limiting the maximum RI value reported by the terminal to the maximum RI value of the rank indication to obtain the current CQI value and the current RI value.
In some embodiments, if the real-time temperature value is located in the first interval, the maximum CQI value reported by the terminal is limited to the maximum CQI value max _ CQI _ t1 corresponding to the first interval, and the maximum RI value reported by the terminal is limited to the maximum rank indicator RI value max _ RI _ t1 corresponding to the first interval.
106: and reporting the current CQI value and the current RI value to an eNB base station so that the eNB base station provides the downlink data throughput of the terminal according to the current CQI value and the current RI value.
In some embodiments, if the real-time temperature value is located in the first interval, reporting a first CQI value and a first RI value to an eNB base station, so that the eNB base station provides a first downlink data throughput of the terminal according to the first CQI value and the first RI value; the first CQI value is obtained by limiting the maximum CQI value reported by the terminal to the maximum CQI value of the channel quality indicator corresponding to the first interval, and the first RI value is obtained by limiting the maximum RI value reported by the terminal to the maximum RI value of the rank indicator corresponding to the first interval.
The larger the reported current CQI value and the current RI value is, the faster the downlink speed that the eNB base station can provide to the terminal UE is, and conversely, the smaller the reported current CQI value or the current RI value is, the smaller the downlink speed that the eNB base station can provide to the terminal UE is.
In some embodiments, if the real-time temperature value is maintained in the first interval, reporting a first CQI value and a first RI value to an eNB base station, so that the eNB base station maintains a first downlink data throughput of the terminal according to the first CQI value and the first RI value.
It should be noted that, according to 3GPP 38.306(UE radio access capability), the downlink data throughput is mainly determined according to Modulation Order and MIMO Layer.
Furthermore, according to the 3GPP 38.214 protocol, the network determines a downlink MCS (modulation and code scheme) and a MIMO Layer according to the CQI and RI values reported by the terminal UE in the CSI (Channel state Information) message, where the larger the reported CQI value or RI value is, the faster the downlink speed that the eNB base station can provide to the UE is, and conversely, the smaller the reported CQI value or RI value is, the smaller the downlink speed that the eNB base station can provide to the UE is.
Therefore, based on the current 3GPP spec network, the downlink MCS and MIMO Layer are determined according to the current CQI value and the current RI value of the uplink of the terminal UE, so as to implement smooth adjustment of the downlink data throughput of the terminal, thereby achieving the cooling effect of the terminal.
In some embodiments, when the real-time temperature value is located in the first interval T1, after the eNB base station adjusts the downlink data throughput of the terminal according to the first CQI value and the first RI value, if the real-time temperature value continuously rises, it indicates that the adjustment needs to be continued.
Specifically, if the real-time temperature value increases from being located in the first interval to being located in the second interval, the maximum value of the channel quality indicator CQI and the maximum value of the rank indicator RI corresponding to the second interval are obtained.
And limiting the maximum CQI value reported by the terminal to the maximum CQI value max _ CQI _ t2 corresponding to the second interval, and limiting the maximum RI value reported by the terminal to the maximum rank indicator RI max _ RI _ t2 in the second interval, so as to obtain a second CQI value and a second RI value.
And finally, reporting a second CQI value and a second RI value to the eNB base station so that the eNB base station provides a second downlink data throughput of the terminal according to the second CQI value and the second RI value, wherein the second CQI value is obtained by limiting the maximum CQI value reported by the terminal to the maximum CQI value corresponding to the second interval, and the second RI value is obtained by limiting the maximum RI value reported by the terminal to the maximum RI value corresponding to the second interval.
As shown in the temperature rise curve of fig. 7, the first interval may correspond to an interval T1, and the second interval may correspond to an interval T2.
Because the temperature when the real-time temperature value is in the first interval is obviously lower than the temperature in the second interval, in order to reduce heat, the second downlink data throughput sent to the terminal by the eNB base station is lower than the first downlink data throughput, so that the terminal can be effectively cooled.
In some embodiments, the temperature change curve may further include a temperature drop curve, and similarly, the temperature drop curve may also include at least two adjacent temperature intervals, for example, the real-time temperature value is decreased from being located in the first interval to being located in the third interval, and when the real-time temperature value is decreased, the eNB base station is required to relax the downlink data throughput, so as to effectively improve the downlink rate.
Specifically, the temperature interval further includes a third interval, and a maximum temperature value of the third interval is smaller than a minimum temperature value of the first interval; the obtaining of the maximum value of the channel quality indicator CQI and the maximum value of the rank indicator RI corresponding to the temperature interval further includes:
if the real-time temperature value is reduced from being located in the first interval to being located in the third interval, acquiring a maximum value of a Channel Quality Indicator (CQI) and a maximum value of a Rank Indicator (RI) corresponding to the third interval;
the reporting the current CQI value and the current RI value to an eNB base station, so that the eNB base station provides the downlink data throughput of the terminal according to the current CQI value and the current RI value, further includes:
reporting a third CQI value and a third RI value to an eNB base station so that the eNB base station provides a third downlink data throughput of the terminal according to the third CQI value and the third RI value; the third CQI value is obtained by limiting the maximum CQI value reported by the terminal to the maximum CQI value of the channel quality indicator corresponding to the third interval, and the third RI value is obtained by limiting the maximum RI value reported by the terminal to the maximum RI value of the rank indicator corresponding to the third interval.
And when the real-time temperature value of the terminal is reduced to a certain temperature interval, adjusting the max-cqi value and the max-ri value in the same way, so that the eNB improves the downlink data throughput of the terminal.
It can be understood that, because the real-time temperature value decreases, the third downlink data throughput sent by the eNB base station to the terminal is greater than the first downlink data throughput, thereby effectively improving the downlink rate.
As shown in fig. 7, in the temperature drop curve, the first interval falls to be located in the third interval, and the first interval may correspond to an interval T1, and the third interval may correspond to an interval T2.
In some embodiments, a buffer zone is arranged between every two adjacent temperature intervals, the buffer zone between the first interval and the second interval is a first buffer zone, and the buffer zone between the first interval and the third interval is a second buffer zone; the method further comprises the following steps:
if the real-time temperature value is increased from the first interval to the second interval, keeping the first CQI value and the first RI value in the first buffer area;
and if the real-time temperature value is reduced from the first interval to the third interval, keeping the first CQI value and the first RI value in the second buffer area.
As shown in fig. 7, no matter the temperature rise curve or the temperature drop curve of the temperature variation curve, a buffer area is disposed between every two adjacent temperature intervals, for example, in the temperature rise curve, the buffer area between the first interval and the second interval is the first buffer area, and in the temperature drop curve, the buffer area between the first interval and the third interval is the second buffer area.
If the real-time temperature value is increased from being located in the first interval to being located in the second interval, the first CQI value and the first RI value are kept in the first buffer, that is, the first CQI value and the first RI value before the increase are kept for a period of time, and when the real-time temperature value is located in the second interval, the first CQI value and the first RI value reported by the terminal are respectively adjusted to the channel quality indication CQI maximum value and the rank indication RI maximum value corresponding to the second interval, so that the rate is prevented from being suddenly reduced during downlink data, and the downlink data throughput fast change caused by repeatedly setting max-CQI values and RI values in a short time is prevented.
Correspondingly, if the real-time temperature value is decreased from being located in the first interval to being located in the third interval, the first CQI value and the first RI value, that is, the first CQI value and the first RI value before the decrease, are maintained in the second buffer, and when the real-time temperature value is located in the third interval, the first CQI value and the first RI value reported by the terminal are respectively adjusted to the maximum channel quality indicator CQI value and the maximum rank indicator RI value corresponding to the third interval, so that the rate is prevented from being suddenly increased during downlink data, and the fast change of the downlink data throughput due to the fact that the max-CQI value and the RI value are set back and forth in a short time is prevented.
Therefore, the buffer area is arranged, so that the ping-pong effect of the back-and-forth jump of the downlink speed can be avoided, and the temperature rise at once after the temperature reduction is avoided.
It can be understood that the present disclosure is not limited to the arrangement of the buffer to prevent the ping-pong effect of the back-and-forth bouncing of the downlink speed, and may also be implemented in other manners, and of course, even if there is no buffer, the ping-pong effect of the back-and-forth bouncing of the downlink speed can also be prevented to a certain extent due to the arrangement of a plurality of temperature zones, and the adjustment is made smoother only after the buffer is arranged.
