Referring to fig. 1, fig. 1 is a first flowchart of a method for reporting a reference signal received power value according to an embodiment of the present application. The method for reporting the reference signal receiving power value comprises the following steps:
step 101, determining a first singular value corresponding to a first antenna port and a second singular value corresponding to a second antenna port according to a current cell reference signal.
Specifically, the mobile terminal performs channel estimation using the reference signal of the current cell to calculate the channel matrix H. The channel matrix model is shown in fig. 2. As can be seen from the figure 2 of the drawings,

Wherein the column vector of U is the left singular vector of the channel matrix H; the column vector of V is the right singular vector of the channel matrix H; Σ is a vector composed of singular values decomposed by the channel matrix H.
Through singular decomposition of the matrix, the transmitting end and the receiving end of the two antennas are respectively multiplied by the conjugate full-time matrices of V and U for processing, as shown in fig. 3, fig. 3 is a schematic flow diagram of the multiplication processing of the conjugate transpose matrices of V and U.

Namely:
Figure BDA0002294227170000042
wherein, if the condition number is closer to 1, the transmission condition of each parallel sub-channel in the channel is good and even; the larger the ratio is, the better or worse the transmission conditions of the sub-channels are, the better or worse the transmission conditions are. So as to know which sub-channels have good conditions and which sub-channels have poor conditions.
Step 102, measuring a first reference signal received power value of a first antenna port and measuring a second reference signal received power value of a second antenna port.
Specifically, the reference signal received power value (RSRP) is a value of signal strength measured by the mobile terminal, and is a value calculated by performing linear average on a cell-specific reference signal on a measurement carrier, and the specific measurement manner is not described herein again.
And 103, reporting the reference signal receiving power value according to the first singular value, the second singular value, the first reference signal receiving power value and the second reference signal receiving power value.
Specifically, the reported RSRP value needs to be considered from multiple angles according to the first singular value and the second singular value calculated in step 101, and in combination with the first reference signal received power value and the second reference signal received power value measured in step 102.
When one RSRP value of the two antennas is greater than or equal to the preset reference signal received power threshold and the other RSRP value of the two antennas is less than or equal to the preset reference signal received power threshold, it may be determined that the channel quality of the antenna having the RSRP value greater than or equal to the preset reference signal received power threshold is good, and the channel quality of the other antenna is poor, and the RSRP value of the antenna having the good channel quality is directly reported to the network side. Therefore, reporting the reference signal receiving power value according to the first singular value, the second singular value, the first reference signal receiving power value and the second reference signal receiving power value includes:
and reporting the first reference signal receiving power value when the first reference signal receiving power value is greater than or equal to a preset reference signal receiving power threshold value and the second reference signal receiving power value is less than or equal to the preset reference signal receiving power threshold value. And if the first reference signal receiving power value and the second reference signal receiving power value are less than or equal to the preset reference signal receiving power threshold, indicating that the user equipment is off-line.
In addition, if the first reference signal received power value and the second reference signal received power value are greater than or equal to the preset reference signal received power threshold, or the first reference signal received power value and the second reference signal received power value are less than or equal to the preset reference signal received power threshold, reporting cannot be performed in the above manner, and therefore, a determination condition may be added to detect whether a singular value of the first singular value and the second singular value acquired in step 101 is 0. If λ1And lambda2One of which is 0, indicates that the two sub-channels have correlation and are degraded into one sub-channel. Therefore, only RSRP values of antennas whose singular values are not 0 are transmitted. Thus, step 103 further comprises: if the first reference signal receiving power value and the second reference signal receiving power value are greater than or equal to a preset reference signal receiving power threshold value, or the first reference signal receiving power value and the second reference signal receiving power value are less than or equal to the preset reference signal receiving power threshold value, detecting whether a singular value in the first singular value and the second singular value is 0, and obtaining a detection result;
if the detection result is that the first singular value is 0, reporting the second reference signal receiving power value;
and if the detection result is that the second singular value is 0, reporting the first reference signal receiving power value.
If the first singular value and the second singular value are not both 0, adding a judgment condition again, checking the condition number in the step 101, and if the condition number is closer to 1, indicating that the transmission conditions of each parallel sub-channel in the channel are good and even; the larger the ratio is, the better or worse the transmission conditions of the sub-channels are, the better or worse the transmission conditions are. At this time, the reporting of the RSRP value of the antenna with good transmission condition may be performed, so that after detecting whether one singular value exists in the first singular value and the second singular value is 0 and obtaining a detection result, the method further includes:
if the first singular value and the second singular value are not 0, comparing the first singular value with the second singular value to obtain a comparison result;
calculating the ratio of the first singular value to the second singular value to obtain a target ratio;
and reporting the first reference signal receiving power value or the second reference signal receiving power value based on the comparison result and the target ratio.
And when the comparison result shows that the first singular value is larger than the second singular value and the target ratio is infinite, reporting the first reference signal receiving power value.
And when the comparison result shows that the second singular value is larger than the first singular value and the target ratio is infinite, reporting the second reference signal receiving power value.
If the target ratio is not infinite, adding a judgment condition, namely performing weighted summation processing on the first singular value and the second singular value to obtain a target reference signal receiving power value, and reporting the target reference signal receiving power value.
In particular, the method comprises the following steps of,
Figure BDA0002294227170000051
and calculating the target reference signal receiving power value according to the following formula:
Figure BDA0002294227170000052
this equation combines the two antennas, antenna ports 0 andthe values measured by the antenna port 1 are weighted-averaged and summed according to the ratio of singular values resolved by the channel conditions. It can be seen that, if the channel condition of a certain antenna port is good, the RSRP value reported last is more biased to the value with good channel condition. Such values are closer to the actual channel conditions, helping the network to better schedule the mobile terminals.
The method for reporting the reference signal received power value provided by the embodiment of the application comprises the following steps: determining a first singular value corresponding to a first antenna port and a second singular value corresponding to a second antenna port according to a current cell reference signal; measuring a first reference signal received power value of a first antenna port and measuring a second reference signal received power value of a second antenna port; and reporting the reference signal receiving power value according to the first singular value, the second singular value, the first reference signal receiving power value and the second reference signal receiving power value. And the singular value and the reference signal receiving power value are flexibly reported to a network side, so that the utilization rate of an antenna channel is improved. Referring to fig. 4, fig. 4 is a second flowchart illustrating a method for reporting a reference signal received power value according to an embodiment of the present application. The method comprises the following steps:
step 201, determining a first singular value corresponding to the first antenna port and a second singular value corresponding to the second antenna port according to the reference signal of the current cell.
Specifically, the mobile terminal performs channel estimation using the reference signal of the current cell to calculate the channel matrix H. The channel matrix model is shown in fig. 2. As can be seen from the figure 2 of the drawings,

Multiplying the conjugate transpose matrix of fig. 3 to obtain Y ═ UHHVX；Y＝UH(UΣVH) VX; y is I Σ IX; y ═ Σ X; by the formula, will

Thus, it is known that the channel quality is represented by λ1And lambda2Determined, condition number

Namely:
Figure BDA0002294227170000069
wherein, if the condition number is closer to 1, the transmission condition of each parallel sub-channel in the channel is good and even; the larger the ratio is, the better or worse the transmission conditions of the sub-channels are, the better or worse the transmission conditions are. So as to know which sub-channels have good conditions and which sub-channels have poor conditions.
Step 202, measure a first reference signal received power value of the first antenna port and measure a second reference signal received power value of the second antenna port.
Specifically, the reference signal received power value (RSRP) is a value of signal strength measured by the mobile terminal, and is a value calculated by performing linear average on a cell-specific reference signal on a measurement carrier, and the specific measurement manner is not described herein again.
Step 203, reporting the first reference signal received power value when the first reference signal received power value is greater than or equal to the preset reference signal received power threshold and the second reference signal received power value is less than or equal to the preset reference signal received power threshold.
When one RSRP value of the two antennas is greater than or equal to the preset reference signal received power threshold and the other RSRP value of the two antennas is less than or equal to the preset reference signal received power threshold, it may be determined that the channel quality of the antenna having the RSRP value greater than or equal to the preset reference signal received power threshold is good, and the channel quality of the other antenna is poor, and the RSRP value of the antenna having the good channel quality is directly reported to the network side.
Step 204, if the first reference signal received power value and the second reference signal received power value are greater than or equal to the preset reference signal received power threshold, or the first reference signal received power value and the second reference signal received power value are less than or equal to the preset reference signal received power threshold, detecting whether a singular value in the first singular value and the second singular value is 0, and obtaining a detection result.
And if the first reference signal receiving power value and the second reference signal receiving power value are less than or equal to the preset reference signal receiving power threshold, indicating that the user equipment is off-line. Therefore, a determination condition may be added to detect whether a singular value of the first singular value and the second singular value obtained in step 201 is 0. If λ1And lambda2One of which is 0, indicates that the two sub-channels have correlation and are degraded into one sub-channel. Therefore, only RSRP values of antennas whose singular values are not 0 are transmitted.
And step 205, reporting the second reference signal receiving power value if the detection result is that the first singular value is 0.
And step 206, reporting the first reference signal receiving power value if the detection result is that the second singular value is 0.
And step 207, if the first singular value and the second singular value are not 0, comparing the first singular value with the second singular value to obtain a comparison result.
If the first singular value and the second singular value are not both 0, adding a judgment condition again, checking the condition number in the step 201, and if the condition number is closer to 1, indicating that the transmission conditions of each parallel sub-channel in the channel are good and even; the larger the ratio is, the better or worse the transmission conditions of the sub-channels are, the better or worse the transmission conditions are. At this time, the RSRP value of the antenna with good transmission condition may be reported.
And 208, calculating the ratio of the first singular value to the second singular value to obtain a target ratio.
And 209, reporting the first reference signal receiving power value when the comparison result shows that the first singular value is larger than the second singular value and the target ratio is infinite.
And step 210, reporting the second reference signal receiving power value when the comparison result shows that the second singular value is larger than the first singular value and the target ratio is infinite.
And step 211, if the target ratio is not infinite, performing weighted summation processing on the first singular value and the second singular value to obtain a target reference signal receiving power value, and reporting the target reference signal receiving power value.
If the target ratio is not infinite, adding a judgment condition, namely performing weighted summation processing on the first singular value and the second singular value to obtain a target reference signal receiving power value, and reporting the target reference signal receiving power value.
In particular, the method comprises the following steps of,
Figure BDA0002294227170000081
and calculating the target reference signal receiving power value according to the following formula:
Figure BDA0002294227170000082
the formula performs weighted average summation on the measured values of the two antennas, antenna port 0 and antenna port 1, according to the proportion of singular values decomposed by channel conditions. It can be seen that, if the channel condition of a certain antenna port is good, the RSRP value reported last is more biased to the value with good channel condition. Such values are closer to the actual channel conditions, helping the network to better schedule the mobile terminals.
The method for reporting the reference signal received power value provided by the embodiment of the application comprises the following steps: determining a first singular value corresponding to a first antenna port and a second singular value corresponding to a second antenna port according to a current cell reference signal; measuring a first reference signal received power value of a first antenna port and measuring a second reference signal received power value of a second antenna port; and reporting the reference signal receiving power value according to the first singular value, the second singular value, the first reference signal receiving power value and the second reference signal receiving power value.
