Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is 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, applied to a network device, including:
and step 21, receiving the quality information of the received signals reported by the terminal. The terminal can periodically report the quality information of the received signal at the position where the terminal is located.
Step 22, determining a first power level at which the terminal is expected to work 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 work of the terminal, sending a power level adjusting instruction to the terminal.
It should be noted that, according to the specification of 3GPP protocol, the maximum transmission power of the terminal depends on P on the network sideEMAX,c(PEMAX,cMaximum transmit power of the terminal maintained for the network side) and the power class P of the terminal itselfPowerClassThe smaller of these. And when P on the network sideEMAX,cSet to NU LL (null), the maximum transmit power of the terminal depends on the power level P of the terminal itselfPowerClass. For example, for a normal terminal with power class 3, no matter P on the network sideEMAX,cThe highest emitted power of a normal terminal of power class 3 can only be 23dBm, set to 23dBm or 26dBm or NU LL, while the P on the network side is used to enable a high-power terminal of power class 2 in the network to emit high power up to 26dBmEMAX,cIt needs to be set to 26dBm or NU LL.
In the above embodiment of the present invention, the P on the network sideEMAX,cSet to 26 or NU LL, and the terminal mentioned in the embodiment of the present invention can support two Power classes, Power Class 3(Power Class 3) and Power Class 2(Power Class 2), respectively.
The first power level may be a power level 3 or a power level 2, and the second power level may also be a power level 3 or a power level 2.
Further, in the above embodiment of the present invention, the method further includes:
determining critical information of terminal power level conversion;
accordingly, step 22 comprises:
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 critical information for terminal power level transition includes: critical RSRP value of terminal power level transition.
The critical RSRP value is a switching point of the terminal between the power level 2 and the power level 3, namely when the RSRP value of the terminal is less than or equal to the critical RSRP value, the power consumption of a single bit of the terminal working at the power level 2 is lower than that of the single bit of the terminal working at the power level 3; when the RSRP value of the terminal > the 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 has more optimized single-bit power consumption when operating at power level 2); when the RSRP value of the terminal is greater than the critical RSRP value, the network side expects the terminal to operate at power level 3 (with more optimal single-bit power consumption when operating at power level 3).
As an embodiment, the determining the critical information of terminal power level transition includes:
receiving terminal power grade conversion critical information reported by a terminal; alternatively, the first and second electrodes may be,
and determining preset terminal power level conversion critical information.
The terminal is normally started to carry out network attachment, and reports the terminal power level conversion critical information of the terminal at a terminal capacity reporting stage. Due to different implementation manners of the terminals, the respective "terminal power level transition critical information" of each terminal may be the same or different. Typically, the critical RSRP value is found in the range of [ -120, -90 ]. If the terminal does not report the critical RSRP value, the network side may select a preset default value, for example, the threshold RSRP value may be-110 dBm.
As an embodiment, the determining a 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 transition critical information includes:
if the RSRP value reported by the terminal is larger than the critical RSRP value, determining that a first power level expected to work by the terminal is a power level 3;
accordingly, step 23 comprises:
when the second power level of the current work of the terminal is a power level 2, sending a first adjusting instruction of the power level to the terminal; the first adjustment instruction is used for instructing the terminal to change the power level from power level 2 to power level 3.
In this case, after the terminal changes the power class, the power headroom PHR is calculated according to the power class 3 and reported to the network.
As another embodiment, the determining a 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 transition critical information includes:
if the RSRP value reported by the terminal is less than or equal to the critical RSRP value, determining that a first power level expected to work by the terminal is a power level 2;
accordingly, step 23 comprises:
when the second power level of the current work of the terminal is a power level 3, sending a second adjusting instruction of the power level to the terminal; the second adjustment instruction is used for instructing the terminal to change the power level from power level 3 to power level 2.
In this case, after the terminal changes the power class, the power headroom PHR is calculated according to the power class 2 and reported to the network.
It should be noted that, if the RSRP value reported by the terminal is less than or equal to the critical RSRP value, and the second power level of the current operation of the terminal is 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 of the current work of the terminal is the power level 3, the network side does not need to send an adjustment instruction, and the terminal can continue to work according to the default power level 3 and calculate the power headroom PHR to report to the network side.
Optionally, in the above 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 current working second power level of the terminal.
In the embodiment of the invention, a power level state identifier is set, and the power level state identifier of the current working power level of the terminal is carried when the terminal reports the capability to the network. For example, when the terminal reports the capability to the network and the initial default reported power level is 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 reported power level is power level 3, the 'power level state mark' is set as B.
The network side device may determine a second power level at which the terminal is currently operating according to the stored power level status identifier.
Further, when the first power level does not match a second power level at which the terminal is currently operating, after sending an adjustment instruction of the power level to the terminal, in order to ensure validity of the power level state 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 level status flag" is a at this time, the network issues a first adjustment instruction to the terminal and changes the "power level status flag" on 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) and reports the PHR) to the network;
when the RSRP value received by the network is less than or equal to the critical RSRP value and the power level state identifier is B, the network issues a second adjustment instruction to the terminal and changes the power level state identifier of the network side to A; after receiving the second adjustment instruction, the terminal changes the Power level of the terminal from Power level 3(Power Class 3) to Power level 2(Power Class 2), calculates the PHR according to Power level 2(Power Class 2), and reports the PHR to the network.
In summary, in the above embodiments of the present invention, according to the received signal quality information reported by the terminal, when the first power level at which the terminal is expected to operate is not matched with the second power level at which the terminal is currently operating, the network side device sends the power level adjustment instruction to the terminal, 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, applied to a terminal, including:
step 31, receiving a power level adjustment instruction sent by a network side device;
and step 32, changing the power grade of the terminal according to the adjusting instruction.
It should be noted that, according to the specification of 3GPP protocol, the maximum transmission power of the terminal depends on P on the network sideEMAX,c(PEMAX,cMaximum transmit power of the terminal maintained for the network side) and the power class P of the terminal itselfPowerClassThe smaller of these. And when P on the network sideEMAX,cSet to NU LL (null), the maximum transmit power of the terminal depends on the power level P of the terminal itselfPowerClass. For example, for a normal terminal with power class 3, no matter P on the network sideEMAX,cThe highest emitted power of a normal terminal of power class 3 can only be 23dBm, set to 23dBm or 26dBm or NU LL, while the P on the network side is used to enable a high-power terminal of power class 2 in the network to emit high power up to 26dBmEMAX,cIt needs to be set to 26dBm or NU LL.
In the above embodiment of the present invention, the P on the network sideEMAX,cSet to 26 or NU LL, and the terminal mentioned in the embodiment of the present invention can support two Power classes, Power Class 3(Power Class 3) and Power Class 2(Power Class 2), respectively.
Further, in the above embodiment of the present invention, the method further includes:
reporting the quality information of the received signal to network side equipment; the terminal can periodically report the quality information of the received signal at the position where the terminal is located.
Optionally, the method further includes:
and reporting the critical information of the terminal power level conversion to the network side equipment.
Preferably, the received signal quality information reported by the terminal includes: a Reference Signal Received Power (RSRP) value; the critical information for terminal power level transition includes: critical RSRP value of terminal power level transition.
The critical RSRP value is a switching point of the terminal between the power level 2 and the power level 3, namely when the RSRP value of the terminal is less than or equal to the critical RSRP value, the power consumption of a single bit of the terminal working at the power level 2 is lower than that of the single bit of the terminal working at the power level 3; when the RSRP value of the terminal > the 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 has more optimized single-bit power consumption when operating at power level 2); when the RSRP value of the terminal is greater than the critical RSRP value, the network side expects the terminal to operate at power level 3 (with more optimal single-bit power consumption when operating at power level 3).
The terminal is normally started to carry out network attachment, and reports the terminal power level conversion critical information of the terminal at a terminal capacity reporting stage. Due to different implementation manners of the terminals, the respective "terminal power level transition critical information" of each terminal may be the same or different. Typically, the critical RSRP value is found in the range of [ -120, -90 ]. If the terminal does not report the critical RSRP value, the network side may select a preset default value, for example, the threshold RSRP value may be-110 dBm.
As an example, step 31 comprises:
receiving a first adjusting instruction of a power level sent by network side equipment;
accordingly, step 32 comprises:
and changing the power level of the terminal from the power level 2 to the power level 3 according to the first adjusting instruction.
In this case, after the terminal changes the power class, the power headroom PHR is calculated according to the power class 3 and reported to the network.
As another example, step 31 includes:
receiving a second adjusting instruction of the power level sent by the network side equipment;
accordingly, step 32 includes:
and changing the power level of the terminal from 3 to 2 according to the second adjusting instruction.
In this case, after the terminal changes the power class, the power headroom PHR is calculated according to the power class 2 and reported to the network.
It should be noted that, if the RSRP value reported by the terminal is less than or equal to the critical RSRP value, and the second power level of the current operation of the terminal is 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 of the current work of the terminal is the power level 3, the network side does not need to send an adjustment instruction, and the terminal can continue to work according to the default power level 3 and calculate the power headroom PHR to report to the network side.
Optionally, in the above embodiment of the present invention, the method further includes:
and reporting a power level state identifier for indicating the current working second power level of the terminal to the network side equipment.
In the embodiment of the invention, a power level state identifier is set, and the power level state identifier of the current working power level of the terminal is carried when the terminal reports the capability to the network. For example, when the terminal reports the capability to the network and the initial default reported power level is 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 reported power level is power level 3, the 'power level state mark' is set as B.
The network side device may determine a second power level at which the terminal is currently operating according to the stored power level status identifier.
Optionally, in another embodiment of the present invention, the method further includes:
and starting a control clock after the power grade of the terminal is changed, and stopping the power grade change of the terminal within 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), in order to avoid the ping-pong switching phenomenon between different Power classes of the terminal, a control clock T may be setcontrolT after one successful handovercontrolIn this case, the terminal does not switch the power level again. For example: if T is to becontrolSet 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, in the above embodiments of the present invention, according to the received signal quality information reported by the terminal, when the first power level at which the terminal is expected to operate is not matched with the second power level at which the terminal is currently operating, the network side device sends the power level adjustment instruction to the terminal, 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.
