Description

Intelligent power saving method and system for LTE terminal, equipment and storage medium

Technical Field

The invention relates to the field of network communication, in particular to an intelligent power saving method, system, equipment and storage medium for an LTE terminal.

Background

LTE (Long Term Evolution ) is a common communication technology standard, and is widely used in various intelligent devices, but in the actual use process, the LTE transmission power is set higher, which causes waste of power consumption.

At present, although there is a control means for LTE power, the power control effect is poor due to the problem of the algorithm itself on which the power control is based, specifically: the sending power of the uplink physical shared channel PUSCH mainly bearing data transmission in the subframe i is as follows:

PPUSCH(i)＝min{PCMAX,10log10(MPUSCH(i))+PO_PUSCH(j)+j)× PL+TF(i)+f(i)}[dBm]

however, in the conventional manner of controlling LTE power by a value of "10log10 (MPUSCH (i)) +po_pusch (j) +j) ×pl+tf (i) +f (i)", since the value is very easy to be larger than PCMAX, power tends to depend on the value of PCMAX instead of the value of "10log10 (MPUSCH (i)) +po_pusch (j) +j) ×pl+tf (i) +f (i)", and thus the actual effect of the conventional means of controlling LTE power is poor.

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will explain the embodiments of the present invention with reference to the attached drawings. It is evident that the drawings in the following description are only examples of the invention, from which other drawings and other embodiments can be obtained by a person skilled in the art without inventive effort.

Example 1:

as shown in fig. 1, this embodiment provides an intelligent power saving method for an LTE terminal, including:

s1: judging whether the signal environment of the terminal is better than a preset signal environment, if so, entering S2;

s2: judging the network rate state of the terminal;

s3: and reducing the maximum transmission power of LTE or the APT voltage according to the state of the network rate.

In the conventional LTE usage process, the power allocation aims to reduce the transmission power of the downlink channel as much as possible on the premise of meeting the user receiving quality, so as to reduce the inter-cell interference, which does not directly change the PCMAX value of the UE (user equipment), that is, the maximum transmission power of the LTE or the APT voltage, but because of the transmission power of the physical shared channel PUSCH in the subframe i:

PPUSCH(i)＝min{PCMAX,10log10(MPUSCH(i))+PO_PUSCH(j)+j)× PL+TF(i)+f(i)}[dBm]

where MPUSCH (i) represents the number of RBs used for PUSCH transmission in subframe i, po_pusch (j) =po_nomnal_pusch (j) +po_ue_pusch (j) is a semi-statically set power reference value. Wherein, PO_NOMINAL_PUSCH (j) is a cell-specific parameter, PO_UE_PUSCH (j) is a UE-specific parameter, both parameters are indicated by high-level signaling, and the parameters can be used for setting different values for different uplink transmission data packets; (j) Is a cell-specific compensation amount for path loss, and when j=0 or 1, {0,0.4,0.5,0.6,0.7,0.8,0.9,1}, is controlled by higher layer signaling. When j=2, (j) =1; PL is based on the UE's estimate of the downlink, the resulting open loop pathloss compensation. TF is a power adjustment value based on MCS. The MCS-based power adjustment may cause the UE to dynamically adjust the corresponding transmit power spectral density according to the selected MCS. The MCS of the UE is scheduled by the eNodeB, and the transmitting power spectrum density of the UE can be quickly adjusted by setting the transmitting MCS of the UE, so that the effect similar to quick power control is achieved; f (i) is an adjustment value of PUSCH current power control, and the parameter is adjusted according to TPC commands on PDCCH.

As can be seen from the above, since the latter equation is easily larger than PCMAX, the transmission power of the physical shared channel PUSCH in the subframe i is largely dependent on the size of PCMAX, and therefore, in the actual operation, since the size of PCMAX is not changed, although LTE has a mechanism for dynamically adjusting the power, in essence, effective adjustment of the power is not realized, and there is still a phenomenon of low rate and high power.

In this embodiment, different PCMAX values, that is, the maximum transmission power or the APT voltage of the LTE, are set according to different network rate scenarios, so that corresponding power levels are selected according to different rate scenarios in a targeted manner, thereby achieving the purpose of power saving of the LTE terminal.

Example 2:

as shown in fig. 2, this embodiment provides an intelligent power saving method for an LTE terminal, including:

s1: judging whether the signal environment of the terminal is better than a preset signal environment or not, if so, entering S2;

s2: judging the network rate state of the terminal, entering S3-1 if the terminal is in a preset medium-speed network state, and entering S3-2 if the terminal is in a preset low-speed network state;

s3-1: reducing LTE maximum transmitting power or APT voltage according to the medium rate reduction amplitude;

s3-2: reducing the LTE maximum transmission power or the APT voltage according to the low-rate reduction amplitude; the low rate reduction amplitude is greater than the medium rate reduction amplitude.

In this embodiment, the reduction of the LTE maximum transmission power or APT voltage may be achieved not only by setting the PCMAX value itself, but also by changing the APT voltage, and in general, if in a high-rate state, that is, in a state where no setting is made, the LTE maximum transmission power is set to 23dbm, and the APT voltage is 3.3V; if the LTE transmitting power is set to be 10dBm at maximum in a medium speed state, the APT voltage is 1.5V; in the low-rate state, the maximum transmission power of the LTE is set to be 0dBm, the APT voltage is 1V, and the specific maximum transmission power of the LTE or the APT voltage can be adjusted according to the actual radio frequency performance.

Example 3:

as shown in fig. 3, this embodiment provides an intelligent power saving method for an LTE terminal, including:

s2-1: judging the network state of a downlink channel of the terminal, entering S3-1 if the terminal is in a preset medium-speed network state, and entering S3-2 if the terminal is in a preset low-speed network state;

s3-3: if the terminal is in a preset medium-speed network state, reducing the LTE maximum transmitting power or the APT voltage of the downlink channel according to the medium-speed reduction amplitude;

s3-4: if the terminal is in a preset low-rate network state, reducing the LTE maximum transmitting power or the APT voltage of the downlink channel according to a low-rate reduction amplitude; the low rate reduction amplitude is greater than the medium rate reduction amplitude;

s2-2: judging the network state of an uplink channel of the terminal, entering S3-5 if the terminal is in a preset medium-speed network state, and entering S3-6 if the terminal is in a preset low-speed network state;

s3-5: if the terminal is in a preset medium-speed network state, reducing the LTE maximum transmitting power or the APT voltage of the uplink channel according to the medium-speed reduction amplitude;

s3-6: if the terminal is in a preset low-rate network state, reducing the maximum transmitting power or APT voltage of the uplink channel LTE according to a low-rate reduction amplitude; the low rate reduction amplitude is greater than the medium rate reduction amplitude;

in this embodiment, since the uplink and downlink flows are not consistent in the network communication process, especially for most of the non-commercial users, the downlink flow is often much larger than the uplink flow, so in the actual use process, in order to achieve more accurate power control, the uplink power and the downlink power can be controlled separately, on the one hand, the original uplink or downlink power requirement is not affected, and on the other hand, the electric quantity can be saved as much as possible, thereby achieving the electric power saving as much as possible.

Example 4:

as shown in fig. 4, this embodiment provides an intelligent power saving system for an LTE terminal, including: the signal strength judging module is used for judging whether the signal environment where the terminal is positioned is better than a preset signal environment; the network rate judging module is used for judging the network rate state of the terminal when the signal environment of the terminal is better than the preset signal environment; and the power adjusting module is used for reducing the maximum LTE transmitting power or the APT voltage according to the state of the network rate.

PPUSCH (i) =min { PCMAX,10log10 (MPUSCH (i))+po_pusch (j) +j) ×pl+tf (i) +f (i) } [ dBm ], where MPUSCH (i) represents the number of RBs used for PUSCH transmission in subframe i, po_pusch (j) =po_nomnal_pusch (j) +po_ue_pusch (j) is a semi-statically set power reference value. Wherein, po_node_pusch (j) is a cell-specific parameter, po_ue_pusch (j) is a UE-specific parameter, both parameters are indicated by high layer signaling, and the parameters can be used to set different values for different uplink transmission data packets.

As described above, the transmission power of the physical shared channel PUSCH in the subframe i is greatly dependent on the PCMAX value, and thus, in the actual operation process, since the PCMAX is not changed, although LTE has a mechanism for dynamically adjusting the power, the efficient adjustment of the power is not realized, and there is still a phenomenon of low rate and high power.
