Description

Background
A high power terminal refers to a terminal having a higher transmit power than a normal terminal, i.e. generally refers to a terminal device with a maximum transmit power of up to 26dBm at the antenna port. The maximum transmit power of the high power terminal is increased by 3dB compared to a normal terminal having a maximum transmit power of 23 dBm.
Successful commercial use of high power terminals has led the entire mobile communications industry, and in particular operators, to the remarkable manifestation of high power terminals in solving the uplink limited problem: under the condition that the network side does not need extra cost input, the uplink limited problem of a TD-LTE (Time Division Long Term Evolution time-division Long Term Evolution) high-frequency cell can be greatly relieved, the uplink rate of a weak coverage area user is obviously improved, the uplink service coverage radius is effectively improved, the Voice over Long-Term Evolution (VoLTE) service experience is improved, and the service experience of an edge user is obviously improved; if the network planning is performed by the high-power terminal, the network construction cost can be saved by 15% -30% for operators. Meanwhile, the high-power terminal can also obviously optimize single-bit power consumption of the terminal at the cell edge.
Fig. 1 is a schematic diagram showing the ratio of single-bit power consumption of a certain high-power terminal device to that of a common terminal device in the prior art. From the outfield test data, a configuration table of laboratory tests is generalized, comprising: transmission rate, uplink and downlink MCS (Modulation and Coding Scheme, modulation and coding strategy), PRB (physical resource block ), uplink transmit power, etc. Setting according to different RSRP (Reference Signal Receiving Power ) on a laboratory comprehensive tester to obtain an uplink speed and a current value, so that a certain high-power terminal device and the same common terminal device are tested; and under the condition of uploading the data volume with the same size, obtaining the single-bit power consumption of the high-power terminal and the common terminal, and further obtaining the ratio of the single-bit power consumption of the high-power terminal and the common terminal. When the ratio is less than 1, it is indicated that the high power has lower single bit power consumption.
As can be seen from fig. 1, in a weak coverage area with RSRP +.110 dBm, a high power terminal of power class 2 has a significant advantage in terms of single bit power consumption compared to a normal terminal of power class 3. But in the non-weak coverage area with RSRP ∈100dBm, the high power terminal of power class 2 is slightly higher in terms of single bit power consumption than the normal terminal of power class 3.

Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2, an embodiment of the present invention provides a power control method, which is applied to a network side device, and includes:
and step 21, receiving the received signal quality information reported by the terminal. The terminal can periodically report the received signal quality information of the position of the terminal.
Step 22, determining a first power level expected to work by the terminal according to the received signal quality information reported by the terminal;
And step 23, when the first power level is not matched with the second power level of the current operation of the terminal, sending a power level adjustment instruction to the terminal.
It should be noted that, according to the specification of the 3GPP protocol, the maximum transmission power of the terminal depends on P at the network side EMAX,c (P EMAX,c Maximum transmit power of the terminal maintained for the network side) and the power class P of the terminal itself PowerClass Is a smaller value of (a). And when P at network side EMAX,c When set to NULL, the maximum transmit power of the terminal depends on the power class P of the terminal itself PowerClass . For example, for a common terminal of power class 3, P on the network side is no matter EMAX,c The highest transmit power of a normal terminal set to 23dBm or 26dBm or NULL, power class 3, can only be 23dBm. In order to enable the high power terminals of power class 2 in the network to emit high power up to 26dBm, P on the network side EMAX,c It needs to be set to 26dBm or NULL.
In the above embodiments of the present invention, P on the network side EMAX,c Set to 26 or NULL, and the terminals mentioned in the embodiments of the present invention can support two Power levels, power level 3 (Power Class 3) and Power level 2 (Power Class 2), respectively.
The first power level may be power level 3 or power level 2, and the second power level may be power level 3 or power level 2.
Further, in the above embodiment of the present invention, the method further includes:
determining terminal power class conversion critical information;
accordingly, step 22 includes:
and determining a first power level expected to work by the terminal according to the received signal quality information reported by the terminal and the terminal power level conversion critical information.
Preferably, the received signal quality information reported by the terminal includes: a reference signal received power RSRP value; the terminal power class switching critical information includes: a critical RSRP value for terminal power class conversion.
The critical RSRP value is a transition point between the power level 2 and the power level 3 of the terminal, that is, when the RSRP value of the terminal is less than or equal to the critical RSRP value, the single-bit power consumption of the terminal operating at the power level 2 is lower than the single-bit power consumption of the terminal operating at the power level 3; when the RSRP value of the terminal > critical RSRP value, the single-bit power consumption of the terminal operating at power level 3 is lower than the single-bit power consumption of the terminal operating at power level 2.
Therefore, when the RSRP value of the terminal is less than or equal to the critical RSRP value, the network side expects the terminal to operate at power level 2 (the terminal operates at power level 2 and has more optimized single-bit power consumption); when the RSRP value of the terminal > the critical RSRP value, the network side expects the terminal to operate at power level 3 (operating at power level 3 with more optimized single-bit power consumption).
As one embodiment, the determining the terminal power class switching threshold information includes:
receiving terminal power grade conversion critical information reported by a terminal; or,
and determining preset terminal power level conversion critical information.
The terminal is normally started to carry out network attachment, and the terminal power class conversion critical information is reported in the terminal capability reporting stage. The respective "terminal power class switching threshold information" may be the same or different for each terminal, depending on the respective implementation of the terminals. In general, the range of values for the critical RSRP is generally found at [ -120, -90]. If the terminal does not report the critical RSRP value, the network side may select a preset default value, for example, the critical RSRP value= -110dBm is preferable.
As one embodiment, the determining the first power level at which the terminal is expected to operate according to the received signal quality information reported by the terminal and the terminal power level conversion critical information includes:
if the RSRP value reported by the terminal is larger than the critical RSRP value, determining that the first power level expected to work by the terminal is power level 3;
accordingly, step 23 includes:
When the second power level of the current work of the terminal is power level 2, a first adjustment instruction of the power level is sent to the terminal; the first adjustment instruction is used for instructing the terminal to change the power level from the power level 2 to the power level 3.
In this case, after the terminal changes the power level, the terminal calculates the power headroom PHR according to the power level 3 and reports the PHR to the network.
As another embodiment, the determining the first power level at which the terminal is expected to operate according to the received signal quality information reported by the terminal and the terminal power level conversion critical information includes:
if the RSRP value reported by the terminal is smaller than or equal to the critical RSRP value, determining that the first power level expected to work by the terminal is power level 2;
accordingly, step 23 includes:
when the second power level of the current work of the terminal is power level 3, a second adjustment instruction of the power level is sent to the terminal; the second adjustment instruction is used for instructing the terminal to change the power level from the power level 3 to the power level 2.
In this case, after the terminal changes the power level, the terminal calculates the power headroom PHR according to the power level 2 and reports the PHR to the network.
It should be noted that, if the RSRP value reported by the terminal is smaller than or equal to the critical RSRP value, and the second power level currently operated by the terminal is the power level 2 at this time, the network side does not need to send an adjustment instruction, and the terminal can continue to operate according to the default power level 2 and calculate the power headroom PHR to report to the network side. And if the RSRP value reported by the terminal is greater than the critical RSRP value and the second power level currently operated by the terminal is the power level 3, the network side does not need to send an adjustment instruction, and the terminal can continue to operate according to the default power level 3 and calculate the power headroom PHR to report to the network side.
Optionally, in the foregoing embodiment of the present invention, the method further includes:
and receiving and storing a power level state identifier, which is reported by the terminal and used for indicating the second power level of the current operation of the terminal.
In the embodiment of the invention, a power class state identifier is set, and the power class state identifier of the current working power class is carried when the terminal reports the capacity to the network. For example, when the terminal reports the capability to the network and initially defaults to report the power level as power level 2, the "power level status flag" is set to a; when the terminal reports the capability to the network and the initial default reporting power level is power level 3, the "power level status identifier" is set to B.
The network side device may determine a second power level at which the terminal is currently operating based on the stored power level status identification.
Further, after sending a power level adjustment instruction to the terminal when the first power level does not match the second power level currently operated by the terminal, in order to ensure the validity of the power level status identifier, the method further includes:
and updating the power level state identification of the terminal.
For example, when the RSRP value received by the network is greater than the critical RSRP value and the "power class status identifier" is a, the network issues a first adjustment instruction to the terminal, and changes the "power class status identifier" at the network side to B; after receiving the first adjustment instruction, the terminal changes the Power level of the terminal from the original Power level 2 (Power Class 2) to the Power level 3 (Power Class 3), and calculates PHR according to the Power level 3 (Power Class 3) to report to the network;
when the RSRP value received by the network is smaller than or equal to the critical RSRP value and the power class state identifier is B, the network issues a second adjustment instruction to the terminal and changes the power class state identifier of the network side into A; after receiving the second adjustment instruction, the terminal changes the Power level of the terminal from the Power level 3 (Power Class 3) to the Power level 2 (Power Class 2), calculates PHR according to the Power level 2 (Power Class 2) and reports the PHR to the network.
In summary, according to the received signal quality information reported by the terminal, the network side device in the above embodiment of the present invention sends an adjustment instruction of the power level to the terminal when the first power level at which the terminal works is expected to be not matched with the second power level at which the terminal works currently, so that the terminal changes the power level to the first power level according to the adjustment instruction, and the power consumption of the terminal is optimized by controlling the power level of the terminal.
As shown in fig. 3, an embodiment of the present invention further provides a power level adjustment method, which is applied to a terminal, and includes:
step 31, receiving an adjustment instruction of the power level sent by the network side equipment;
and step 32, changing the power level of the terminal according to the adjustment instruction.
It should be noted that, according to the specification of the 3GPP protocol, the maximum transmission power of the terminal depends on P at the network side EMAX,c (P EMAX,c Maximum transmit power of the terminal maintained for the network side) and the power class P of the terminal itself PowerClass Is a smaller value of (a). And when P at network side EMAX,c When set to NULL, the maximum transmit power of the terminal depends on the power class P of the terminal itself PowerClass . For example, for a common terminal of power class 3, P on the network side is no matter EMAX,c The highest transmit power of a normal terminal set to 23dBm or 26dBm or NULL, power class 3, can only be 23dBm. In order to enable the high power terminals of power class 2 in the network to emit high power up to 26dBm, P on the network side EMAX,c It needs to be set to 26dBm or NULL.
In the above embodiments of the present invention, P on the network side EMAX,c Set to 26 or NULL, and the terminals mentioned in the embodiments of the present invention can support two Power levels, power level 3 (Power Class 3) and Power level 2 (Power Class 2), respectively.
Further, in the above embodiment of the present invention, the method further includes:
reporting the received signal quality information to network side equipment; the terminal can periodically report the received signal quality information of the position of the terminal.
Optionally, the method further comprises:
and reporting the terminal power class conversion critical information to the network side equipment.
Preferably, the received signal quality information reported by the terminal includes: a reference signal received power RSRP value; the terminal power class switching critical information includes: a critical RSRP value for terminal power class conversion.
The critical RSRP value is a transition point between the power level 2 and the power level 3 of the terminal, that is, when the RSRP value of the terminal is less than or equal to the critical RSRP value, the single-bit power consumption of the terminal operating at the power level 2 is lower than the single-bit power consumption of the terminal operating at the power level 3; when the RSRP value of the terminal > critical RSRP value, the single-bit power consumption of the terminal operating at power level 3 is lower than the single-bit power consumption of the terminal operating at power level 2.
Therefore, when the RSRP value of the terminal is less than or equal to the critical RSRP value, the network side expects the terminal to operate at power level 2 (the terminal operates at power level 2 and has more optimized single-bit power consumption); when the RSRP value of the terminal > the critical RSRP value, the network side expects the terminal to operate at power level 3 (operating at power level 3 with more optimized single-bit power consumption).
The terminal is normally started to carry out network attachment, and the terminal power class conversion critical information is reported in the terminal capability reporting stage. The respective "terminal power class switching threshold information" may be the same or different for each terminal, depending on the respective implementation of the terminals. In general, the range of values for the critical RSRP is generally found at [ -120, -90]. If the terminal does not report the critical RSRP value, the network side may select a preset default value, for example, the critical RSRP value= -110dBm is preferable.
As an embodiment, step 31 includes:
receiving a first adjustment instruction of the power level sent by network side equipment;
accordingly, step 32 includes:
and changing the power level of the terminal from the power level 2 to the power level 3 according to the first adjustment instruction.
In this case, after the terminal changes the power level, the terminal calculates the power headroom PHR according to the power level 3 and reports the PHR to the network.
As another embodiment, step 31 includes:
receiving a second adjustment instruction of the power level sent by the network side equipment;
accordingly, step 32 includes:
and changing the power level of the terminal from the power level 3 to the power level 2 according to the second adjustment instruction.
In this case, after the terminal changes the power level, the terminal calculates the power headroom PHR according to the power level 2 and reports the PHR to the network.
It should be noted that, if the RSRP value reported by the terminal is smaller than or equal to the critical RSRP value, and the second power level currently operated by the terminal is the power level 2 at this time, the network side does not need to send an adjustment instruction, and the terminal can continue to operate according to the default power level 2 and calculate the power headroom PHR to report to the network side. And if the RSRP value reported by the terminal is greater than the critical RSRP value and the second power level currently operated by the terminal is the power level 3, the network side does not need to send an adjustment instruction, and the terminal can continue to operate according to the default power level 3 and calculate the power headroom PHR to report to the network side.
Optionally, in the foregoing embodiment of the present invention, the method further includes:
and reporting a power class state identifier for indicating the second power class of the current working terminal to the network side equipment.
In the embodiment of the invention, a power class state identifier is set, and the power class state identifier of the current working power class is carried when the terminal reports the capacity to the network. For example, when the terminal reports the capability to the network and initially defaults to report the power level as power level 2, the "power level status flag" is set to a; when the terminal reports the capability to the network and the initial default reporting power level is power level 3, the "power level status identifier" is set to B.
The network side device may determine a second power level at which the terminal is currently operating based on the stored power level status identification.
Optionally, in a further embodiment of the present invention, the method further includes:
and starting a control clock after changing the power level of the terminal, and stopping changing the power level of the terminal in the running time of the control clock.
When the terminal is at the switching edge of Power Class 2 (Power Class 2) and Power Class 3 (Power Class 3), a control clock T can be set to avoid ping-pong switching between different Power classes control T after one-time switching success control In this, the terminal does not switch the power class again. For example: if T is to be control Set to 10ms, then the terminal will not switch back from power level 3 to power level 2 again within 10ms after the terminal switches from power level 2 to power level 3.
In summary, according to the received signal quality information reported by the terminal, the network side device in the above embodiment of the present invention sends an adjustment instruction of the power level to the terminal when the first power level at which the terminal works is expected to be not matched with the second power level at which the terminal works currently, so that the terminal changes the power level to the first power level according to the adjustment instruction, and the power consumption of the terminal is optimized by controlling the power level of the terminal.
