Background
LTE (Long Term Evolution ) is a common communication technology standard, and is widely used in various intelligent devices, but in an actual use process, LTE transmission power is set to be high, which causes waste of power consumption.
At present, although there is a power control means for LTE, the power control effect is poor due to the problem of the algorithm itself on which the power control is based, specifically: the transmission 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 method of controlling the power of LTE by using the value of "10 log10(mpusch (i)) + PO _ pusch (j)) + j) × PL + tf (i)) + f (i)", since this value is very easily larger than PCMAX, the power during the actual operation process is often dependent on the value of PCMAX rather than the value of "10 log10(mpusch (i)) + PO _ pusch (j)) + PL + tf (i)) + f (i)", so the actual effect of the conventional power control method of LTE is poor.

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following will illustrate specific embodiments of the present invention with reference to the drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
Example 1:
as shown in fig. 1, the present 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 LTE transmitting power or the APT voltage according to the state of the network rate.
In the conventional LTE usage process, the objective of power allocation is to reduce the transmission power of a downlink channel as much as possible on the premise of satisfying the user reception quality, so as to reduce inter-cell interference, which does not directly change the PCMAX value of a UE (user equipment), that is, the LTE maximum transmission power or APT voltage, but because the transmission power of a physical shared channel PUSCH in a subframe i:
PPUSCH(i)＝min{PCMAX,10log10(MPUSCH(i))+PO_PUSCH(j)+j)× PL+TF(i)+f(i)}[dBm]
where mpusch (i) indicates the number of RBs used for PUSCH transmission in subframe i, and PO _ PUSCH (j) ═ PO _ normal _ 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 to set different values for different uplink transmission data packets; (j) is the amount of cell-specific compensation for path loss, {0,0.4,0.5,0.6,0.7,0.8,0.9,1} when j is 0 or 1, controlled by higher layer signaling. When j is 2, (j) is 1; PL is the resulting open loop path loss compensation based on the UE's estimate for the downlink. TF is a MCS-based power adjustment value. MCS-based power adjustments 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 spectral 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; and f (i) is the adjustment value of the current power control of the PUSCH, and the parameter is adjusted according to the TPC command on the PDCCH.
As can be seen from the above, since the latter equation is easily larger than PCMAX, the transmission power of the PUSCH in the subframe i depends on the value of PCMAX, and therefore, in the actual operation process, since the value of PCMAX is not changed, although LTE has a mechanism for dynamically adjusting power, it does not achieve effective adjustment of power per se, and there is a phenomenon of low rate and high power.
In the embodiment, different PCMAX values, that is, the maximum LTE transmit power or the APT voltage, are set according to different network rate scenarios, so that corresponding power is selected according to different rate scenarios in a targeted manner, and the purpose of saving power for the LTE terminal is achieved.
Example 2:
as shown in fig. 2, the present 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, entering S3-1 if the terminal is in a preset medium rate network state, and entering S3-2 if the terminal is in a preset low rate network state;
s3-1: reducing the maximum LTE transmitting power or the APT voltage according to the medium-speed reduction amplitude;
s3-2: reducing the maximum LTE transmitting 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 the APT voltage can be realized not only by setting the PCMAX value itself, but also by changing the APT voltage, and generally, if the LTE maximum transmission power is set to be 23dBm and the APT voltage is set to be 3.3V in a high-rate state, that is, in a state without any setting; if in the medium-rate state, the maximum LTE transmitting power is set to be 10dBm, and the APT voltage is 1.5V; in the low-rate state, the maximum LTE transmission power is set to 0dBm, the APT voltage is 1V, and the specific maximum LTE transmission power or the magnitude of the APT voltage can be adjusted according to the actual radio frequency performance.
Example 3:
as shown in fig. 3, the present 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;
s2-1: judging the network state of a downlink channel of the terminal, and entering S3-1 if the terminal is in a preset medium-rate network state, and entering S3-2 if the terminal is in a preset low-rate network state;
s3-3: if the terminal is in a preset medium-rate network state, reducing the LTE maximum transmitting power or APT voltage of the downlink channel according to the medium-rate reduction amplitude;
s3-4: if the terminal is in a preset low-rate network state, reducing the LTE maximum transmitting power or 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, and entering S3-5 if the terminal is in a preset medium-rate network state, and entering S3-6 if the terminal is in a preset low-rate network state;
s3-5: if the terminal is in a preset medium-rate network state, reducing the LTE maximum transmitting power or APT voltage of the uplink channel according to the medium-rate 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, in the network communication process, the uplink and downlink flows are not consistent, and especially for most users who are not in commercial use, the downlink flow is often much larger than the uplink flow, so in the actual use process, in order to implement more accurate power control, the uplink power and the downlink power can be respectively controlled, on one hand, the original uplink or downlink power requirement is not affected, on the other hand, the electric quantity can be saved as much as possible, and thus, the electric power can be saved as much as possible.
Example 4:
as shown in fig. 4, the present embodiment provides an LTE terminal intelligent power saving system, including: the signal strength judging module is used for judging whether the signal environment of the terminal 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.
In the conventional LTE usage process, the objective of power allocation is to reduce the transmission power of a downlink channel as much as possible on the premise of satisfying the user reception quality, so as to reduce inter-cell interference, which does not directly change the PCMAX value of a UE (user equipment), that is, the LTE maximum transmission power or APT voltage, but because the transmission power of a physical shared channel PUSCH in a subframe i:
ppusch (i) { PCMAX,10log10(mpusch (i)) + PO _ PUSCH (j)) + j × PL + tf (i)) + f (i)) } [ dBm ], where mpusch (i) denotes the number of RBs used for PUSCH transmission in subframe i, and PO _ PUSCH (j) ═ PO _ normal _ PUSCH (j)) + PO _ UE _ PUSCH (j) is a semi-statically set power reference value. The PO _ NOMINAL _ pusch (j) is a cell-specific parameter, and the PO _ UE _ pusch (j) is a UE-specific parameter, both of which are indicated by high-level signaling, and the parameters can be used to set different values for different uplink transmission packets.
As can be seen from the above, the transmission power of the PUSCH in the subframe i depends on the value of the PCMAX to a great extent, and therefore, in an actual operation process, since the value of the PCMAX is not changed, although LTE has a mechanism for dynamically adjusting power, effective adjustment of power is not essentially achieved, and a phenomenon of low rate and high power still exists.
In the embodiment, different PCMAX values, that is, the maximum LTE transmit power or the APT voltage, are set according to different network rate scenarios, so that corresponding power is selected according to different rate scenarios in a targeted manner, and the purpose of saving power for the LTE terminal is achieved.

In this embodiment, the reduction of the LTE maximum transmission power or the APT voltage can be realized not only by setting the PCMAX value itself, but also by changing the APT voltage, and generally, if the LTE maximum transmission power is set to be 23dBm and the APT voltage is set to be 3.3V in a high-rate state, that is, in a state without any setting; if in the medium-rate state, the maximum LTE transmitting power is set to be 10dBm, and the APT voltage is 1.5V; in the low-rate state, the maximum LTE transmission power is set to 0dBm, the APT voltage is 1V, and the specific maximum LTE transmission power or the magnitude of the APT voltage can be adjusted according to the actual radio frequency performance.
