Description

technical field

The present invention relates to the technical field of communications, and in particular to a power control method, a power level adjustment method, a terminal and a network side device.

Background technique

A high-power terminal refers to a terminal that has a higher transmission power than a common terminal, that is, it generally refers to a terminal device whose maximum transmission power from the antenna port can reach 26dBm. Compared with ordinary terminals with a maximum transmission power of 23dBm, the maximum transmission power of high-power terminals is increased by 3dB.

The successful commercial use of high-power terminals has enabled the entire mobile communication industry, especially operators, to appreciate the excellent performance of high-power terminals in solving the problem of uplink limitation: without additional cost investment on the network side, it can greatly alleviate TD-LTE ( Time Division Long Term Evolution (Time Division Long Term Evolution), the uplink limitation problem of high-band cells, significantly improves the uplink rate of users in weak coverage areas, effectively increases the coverage radius of uplink services, and helps to improve VoLTE (Voice over Long-Term Evolution, Long-Term Evolution (Voice Bearer) service experience can significantly improve the service experience of edge users; if high-power terminals are used for network planning, operators can save 15% to 30% of network construction costs. At the same time, high-power terminals can significantly optimize the single-bit power consumption of terminals at the cell edge.

As shown in FIG. 1 , it is a schematic diagram of the ratio of power consumption per bit of a certain type of high-power terminal equipment in the prior art to that of a common terminal equipment of the same type. According to the field test data, the configuration table of the laboratory test is summarized, including: transmission rate, uplink and downlink MCS (Modulation and Coding Scheme, modulation and coding strategy), PRB (physical resource block, physical resource block), uplink transmit power, etc. On the comprehensive tester in the laboratory, according to different RSRP (ReferenceSignal Receiving Power, reference signal receiving power), the uplink rate and current value are obtained, so as to test a certain high-power terminal equipment and the same general terminal equipment; In the case of uploading the same amount of data, the single-bit power consumption of high-power terminals and ordinary terminals is obtained, and then the ratio of single-bit power consumption of high-power terminals to ordinary terminals is obtained. When the ratio is less than 1, it means that high power has lower power consumption per bit.

It can be seen from Figure 1 that in a weak coverage area where RSRP≤-110dBm, compared with ordinary terminals of power level 3, high-power terminals of power level 2 have obvious advantages in power consumption per bit. However, in non-weak coverage areas where RSRP≥-100dBm, compared with common terminals of power level 3, high-power terminals of power level 2 consume slightly more power per bit.

Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

As shown in Figure 2, an embodiment of the present invention provides a power control method, which is applied to a network side device, including:

Step 21, receiving the received signal quality information reported by the terminal. The terminal may periodically report the received signal quality information of the terminal's location.

Step 22, according to the received signal quality information reported by the terminal, determine a first power level at which the terminal is expected to work;

Step 23, when the first power level does not match the second power level that the terminal is currently working on, send a power level adjustment instruction to the terminal.

It should be noted that, according to the 3GPP protocol, the maximum transmission power of the terminal depends on the P _EMAX,c of the network side (P _EMAX,c is the maximum transmission power of the terminal maintained by the network side) and the power level P of the _terminal itself. smaller value. And when P _EMAX,c on the network side is set to NULL (invalid), the maximum transmission power of the terminal depends on the power level P _PowerClass of the terminal itself. For example, for an ordinary terminal of power level 3, no matter P _EMAX,c on the network side is set to 23dBm or 26dBm or NULL, the maximum transmit power of an ordinary terminal of power level 3 can only be 23dBm. In order to enable high-power terminals with power level 2 in the network to transmit high power up to 26dBm, P _EMAX,c on the network side needs to be set to 26dBm or NULL.

In the above-mentioned embodiments of the present invention, the P _EMAX,c on the network side is set to 26 or NULL, and the terminals mentioned in the embodiments of the present invention can support two power levels, respectively, power class 3 (Power Class 3) and power Class 2 (PowerClass 2).

Wherein, the first power level may be power level 3 or power level 2, and the second power level may also be power level 3 or power level 2.

Further, in the above-mentioned embodiment of the present invention, the method also includes:

Determine terminal power level conversion critical information;

Correspondingly, step 22 includes:

Determine the first power level at which the terminal is expected to work according to the received signal quality information reported by the terminal and the terminal power level switching critical information.

Preferably, the received signal quality information reported by the terminal includes: a reference signal received power (RSRP) value; and the terminal power level switching critical information includes: a terminal power level switching critical RSRP value.

Among them, the critical RSRP value is the transition point of the terminal between power level 2 and power level 3, that is, when the terminal’s RSRP value ≤ the critical RSRP value, the single-bit power consumption of the terminal working at power level 2 is lower than that of the terminal at power level The single-bit power consumption of level 3 operation; when the RSRP value of the terminal is greater than the critical RSRP value, the single-bit power consumption of the terminal working at power level 3 is lower than the single-bit power consumption of the terminal working at power level 2.

Therefore, when the RSRP value of the terminal ≤ the critical RSRP value, the network side expects the terminal to work at power level 2 (working at power level 2 has a more optimized single-bit power consumption); when the terminal's RSRP value > critical RSRP value , the network side expects the terminal to work at power level 3 (working at power level 3 has more optimized power consumption per bit).

As an embodiment, the determination of terminal power level switching critical information includes:

receiving terminal power level switching critical information reported by the terminal; or,

Determine preset terminal power level switching critical information.

Among them, the terminal starts up normally to attach to the network, and reports its own "terminal power level switching critical information" during the terminal capability reporting stage. Due to different implementations of the terminals, the "terminal power level switching critical information" of each terminal may be the same or different. Generally, the value range of the critical RSRP value is common in [-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 may be selected.

As an embodiment, the determining the first power level at which the terminal is expected to work 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 greater than the critical RSRP value, determine that the first power level at which the terminal is expected to work is power level 3;

Correspondingly, step 23 includes:

When the second power level that the terminal is currently working on is power level 2, send a first adjustment instruction of the power level to the terminal; the first adjustment instruction is used to instruct the terminal to change the power level from power level 2 For power level 3.

In this case, after changing the power level, the terminal calculates the power headroom PHR according to the power level 3 and reports it to the network.

As another embodiment, the determining the first power level at which the terminal is expected to work 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 less than or equal to the critical RSRP value, determine that the first power level at which the terminal is expected to work is power level 2;

Correspondingly, step 23 includes:

When the second power level at which the terminal is currently working is power level 3, send a second adjustment instruction of the power level to the terminal; the second adjustment instruction is used to instruct the terminal to change the power level from power level 3 for power level 2.

In this case, after changing the power level, the terminal calculates the power headroom PHR according to the power level 2 and reports it 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 that the terminal is currently working at is power level 2, then the network side does not need to send an adjustment command, and the terminal can continue to follow the The default power level 2 works and calculates the power headroom PHR and reports it 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 that the terminal is currently working at is power level 3, then the network side does not need to send an adjustment command, and the terminal can continue to operate according to the default power level 3. Work and calculate the power headroom PHR and report to the network side.

Optionally, in the above-mentioned embodiments of the present invention, the method further includes:

receiving and storing the power level state identifier reported by the terminal and used to indicate the second power level that the terminal is currently working on.

In the embodiment of the present invention, a "power level status identifier" is set, and when the terminal reports the capability to the network, it carries the power level status identifier of its current working power level. For example, when the terminal reports the capability to the network, and initially reports the default power level as power level 2, then the "power level status indicator" is set to A; when the terminal reports the capability to the network, and initially reports the default power level as power When the level is 3, the "power level status flag" is set to B.

The network side device may determine the second power level at which the terminal is currently working according to the stored power level state identifier.

Further, when the first power level does not match the second power level that the terminal is currently working on, after sending a power level adjustment instruction to the terminal, in order to ensure the effectiveness of the power level state identification, the method further includes:

Updating the power level state identifier 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 indicator" is A at this time, the network sends the first adjustment instruction to the terminal, and sets the "power level status indicator" on the network side to ” to B; after the terminal receives the first adjustment instruction, the terminal changes its own terminal power level from the original power level 2 (Power Class 2) to power level 3 (Power Class 3), and follows the power level 3 ( Power Class 3) to calculate PHR) and report 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 status indicator" is B at this time, the network sends a second adjustment instruction to the terminal, and sets the "power level status indicator" on the network side to ” is changed to A; after the terminal receives the second adjustment instruction, the terminal changes its own terminal power level from power level 3 (Power Class 3) back to power level 2 (Power Class 2), and according to the power level of power level 2 (Power Class 2) To calculate the PHR and report it to the network.

To sum up, in the above embodiments of the present invention, according to the received signal quality information reported by the terminal, the network side device sends power to the terminal when the first power level that the terminal is expected to work at does not match the second power level at which the terminal is currently working. The level adjustment command enables the terminal to change the power level to the first power level according to the adjustment command, and optimize the power consumption of the terminal by controlling the power level of the terminal.

As shown in Figure 3, the embodiment of the present invention also provides a power level adjustment method, which is applied to a terminal, including:

Step 31, receiving the power level adjustment instruction sent by the network side device;

Step 32, changing the power level of the terminal according to the adjustment instruction.

It should be noted that, according to the 3GPP protocol, the maximum transmission power of the terminal depends on the P _EMAX,c of the network side (P _EMAX,c is the maximum transmission power of the terminal maintained by the network side) and the power level P of the _terminal itself. smaller value. And when P _EMAX,c on the network side is set to NULL (invalid), the maximum transmission power of the terminal depends on the power level P _PowerClass of the terminal itself. For example, for an ordinary terminal of power level 3, no matter P _EMAX,c on the network side is set to 23dBm or 26dBm or NULL, the maximum transmit power of an ordinary terminal of power level 3 can only be 23dBm. In order to enable high-power terminals with power level 2 in the network to transmit high power up to 26dBm, P _EMAX,c on the network side needs to be set to 26dBm or NULL.

In the above-mentioned embodiments of the present invention, the P _EMAX,c on the network side is set to 26 or NULL, and the terminals mentioned in the embodiments of the present invention can support two power levels, respectively, power class 3 (Power Class 3) and power Class 2 (PowerClass 2).

Further, in the above-mentioned embodiment of the present invention, the method also includes:

Report the received signal quality information to the network side device; the terminal can periodically report the received signal quality information of the terminal's location.

Optionally, the method also includes:

Report terminal power level conversion critical information to the network side device.

Preferably, the received signal quality information reported by the terminal includes: a reference signal received power (RSRP) value; and the terminal power level switching critical information includes: a terminal power level switching critical RSRP value.

Among them, the critical RSRP value is the transition point of the terminal between power level 2 and power level 3, that is, when the terminal’s RSRP value ≤ the critical RSRP value, the single-bit power consumption of the terminal working at power level 2 is lower than that of the terminal at power level The single-bit power consumption of level 3 operation; when the RSRP value of the terminal is greater than the critical RSRP value, the single-bit power consumption of the terminal working at power level 3 is lower than the single-bit power consumption of the terminal working at power level 2.

Therefore, when the RSRP value of the terminal ≤ the critical RSRP value, the network side expects the terminal to work at power level 2 (working at power level 2 has a more optimized single-bit power consumption); when the terminal's RSRP value > critical RSRP value , the network side expects the terminal to work at power level 3 (working at power level 3 has more optimized power consumption per bit).

Among them, the terminal starts up normally to attach to the network, and reports its own "terminal power level switching critical information" during the terminal capability reporting stage. Due to different implementations of the terminals, the "terminal power level switching critical information" of each terminal may be the same or different. Generally, the value range of the critical RSRP value is common in [-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 may be selected.

As an embodiment, step 31 includes:

receiving a first adjustment instruction of the power level sent by the network side device;

Correspondingly, step 32 includes:

According to the first adjustment instruction, the power level of the terminal is changed from power level 2 to power level 3.

In this case, after changing the power level, the terminal calculates the power headroom PHR according to the power level 3 and reports it to the network.

As another embodiment, step 31 includes:

receiving a second adjustment instruction of the power level sent by the network side device;

Correspondingly, step 32 includes:

According to the second adjustment instruction, the power level of the terminal is changed from power level 3 to power level 2.

In this case, after changing the power level, the terminal calculates the power headroom PHR according to the power level 2 and reports it 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 that the terminal is currently working at is power level 2, then the network side does not need to send an adjustment command, and the terminal can continue to follow the The default power level 2 works and calculates the power headroom PHR and reports it 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 that the terminal is currently working at is power level 3, then the network side does not need to send an adjustment command, and the terminal can continue to operate according to the default power level 3. Work and calculate the power headroom PHR and report to the network side.

Optionally, in the above-mentioned embodiments of the present invention, the method further includes:

Reporting to the network side device a power level status identifier used to indicate the second power level that the terminal is currently working on.

In the embodiment of the present invention, a "power level status identifier" is set, and when the terminal reports the capability to the network, it carries the power level status identifier of its current working power level. For example, when the terminal reports the capability to the network, and initially reports the default power level as power level 2, then the "power level status indicator" is set to A; when the terminal reports the capability to the network, and initially reports the default power level as power When the level is 3, the "power level status flag" is set to B.

The network side device may determine the second power level at which the terminal is currently working according to the stored power level state identifier.

Optionally, in yet another embodiment of the present invention, the method further includes:

After changing the power level of the terminal, a control clock is started, and within the running time of the control clock, the terminal stops changing the power level.

When the terminal is on the edge of switching between power class 2 (Power Class 2) and power class 3 (Power Class 3), in order to avoid the phenomenon of ping-pong switching between different power levels in the terminal, a control clock T _control can be set, and the switching is successful once In the following T _control , the terminal will not switch the power level again. For example: if T _control is set to 10ms, then within 10ms after the terminal switches from power level 2 to power level 3, the terminal will not switch back from power level 3 to power level 2 again.

To sum up, in the above embodiments of the present invention, according to the received signal quality information reported by the terminal, the network side device sends power to the terminal when the first power level that the terminal is expected to work at does not match the second power level at which the terminal is currently working. The level adjustment command enables the terminal to change the power level to the first power level according to the adjustment command, and optimize the power consumption of the terminal by controlling the power level of the terminal.
