- the mobile device may be a user equipment (UE).
- UE user equipment

- the UE measurement reports may be saved in a database, a text file, a key-value store, or another data store at the coordination server, and the measurement reports may be indexed by base station, by UE, and by time of the report.
- UE reports may pertain to more than one base station, measurement reports for both the UE's serving base station and for neighbor base stations may be received and stored.
- UE measurement reports may be aggregated for a plurality of UEs. UE measurement reports may later be queried to obtain the measurement reports that pertain to a specific base station that is having its power adjusted, in some embodiments.
- UEs measure two parameters on a reference signal: RSRP (Reference Signal Received Power), which is defined as the linear average in watts of the downlink reference signal across a given channel, and RSRQ (Reference Signal Received Quality), which is defined as the ratio of RSRP to the received signal strength indicator (RSSI).
- RSRP Reference Signal Received Power
- RSRQ Reference Signal Received Quality
- RSRQ is the ratio between the RSRP and the Received Signal Strength Indicator (RSSI), and depending on the measurement bandwidth, means the number of resource blocks. RSSI is the total received wideband power including all interference and thermal noise. As RSRQ combines signal strength as well as interference level, this measurement value provides additional help for mobility decisions.
- RSSI Received Signal Strength Indicator
- the method calculates four metrics to assess interference from the selected base station given an increase in transmit power.
- the first metric that may be calculated is the number of UEs being negatively impacted, i.e., that will see a decrease in performance, when the selected base station increases its power.
- powerStepUP equals the amount by which the power at the selected base station would be increased.
- powerStepUP is configurable.
- powerStepUP is a step of 2 dBm.
- a second metric may be calculated for the number of UEs positively impacted, which typically would be some subset of the UEs currently attached to the selected base station.
- These numbers may be determined by reviewing each measurement report retrieved from a UE and sorting them into UEs that are either positively impacted, negatively impacted, or not impacted at all.
- the signal interference metric is greater than a certain maximum threshold for a given UE, the service being experienced by the UE may be sufficient such that there is no need to increase the ratio for that particular UE, and the UE could be marked as not impacted.
- the signal interference metric is below a certain minimum threshold, link performance may be so degraded that a small improvement in transmit power may not be sufficient to make the link useful for data transmissions to that UE, and the UE could also be marked as not impacted.
- a range between the minimum and maximum threshold exists wherein increasing the signal interference metric will have some effect on the quality of service experienced by the receiving UEs, and UEs in this range should be marked as either positively or negatively impacted.
- the number of UE measurement reports that have not been filtered out and that would be negatively impacted by increasing the power of the selected base station are thus identified, constituting an integer value.
- the ratio of the quality measure at the serving base station to the quality measure at the neighboring base station is mapped to a weighted integer.
- the weight may be based on the number of neighboring base stations or may be based on other factors.
- the weighted integer is summed over all neighboring base stations.
- This value is a measure of the current network performance of the selected base station relative to the UE that it is servicing.
- This value is the first metric, and is also a measure of the deleterious effects of the interference of a given base station on UEs in the network, and a measure of the number of UEs that would be hurt by increasing power on the selected base station has been calculated.
- the first metric may be an integer.
- the second metric is based on the number of UEs that would be helped by decreasing power at the selected base station. For all UEs and for all neighboring base stations, the consequences of decreasing transmit power by powerStepDOWN are evaluated, where powerStepDOWN is an amount by which the power at the selected base station would be decreased.
- the result of the steps of this portion of the algorithm is to determine how many UEs being interfered by the selected base station will see an increase in performance if the selected base station decreases its transmit power. In making this determination, the data set containing the ratios computed above may be used when determining the current network conditions.
- powerStepDOWN is configurable.
- powerStepDOWN is a step of 2 dBm.
- the third metric captures projected consequences of increasing a base station's transmit power on the performance of UEs that are served by it. For all UEs that reported the selected base station as the serving base station, a signal to interference ratio (SINR), which can be determined from the RSRP and the noise level, can be used to determine how much better the performance of a given UE becomes if the selected base station increases its transmit power. For UEs whose signal quality is below a certain threshold, we calculate the third metric using any appropriate function of the signal to interference and noise ratio, computed using RSRQ or RSRP or any other quality measure. Next, the calculated metric may be assigned an appropriate weight and summed with other metrics for other UEs and base stations. This summation is a metric for measuring the benefits of increasing the transmit power of the base station on UEs that are connected to it. This is the third metric, also called the positive consequence metric, and may be a real number.
- the calculation of the fourth metric is described. For all UEs that reported the selected base station as the serving base station, a determination may be made of how much worse their performance becomes if the selected base station decreases its transmit power. For such UEs, signal to interference and noise ratio is a good measure of performance. In LTE, RSRQ may be used, or serving and neighboring cell RSRP measurements reported by the UEs may be used. As well, for UEs whose signal quality is below a certain threshold, a real number may be calculated as any appropriate function of the signal to interference and noise ratio, weight that real number appropriately and include in summation, each of these weighted real numbers. This summation is the fourth metric, also described herein as the negative consequence metric, and measures the detriment of decreasing the transmit power of the base station on UEs that are connected to it. The fourth metric may be a real number.
- each base station four metrics are generated, two generated using the effect of the base stations interference on neighboring UEs and two generated using signal quality of UEs served by said base station.
- Each of these four metrics is considered when assessing whether to adjust transmit power up or down. In some embodiments, these four metrics are added and the sum is evaluated.
- the threshold for increasing power may be a function of X and of normSINRnei(i), where X is the number of users required to benefit to justify increasing power, and normSINRnei(i) is the normal SINR of each neighbor base station of the selected base station.
- the threshold for decreasing power may be a function of X and of normSINRcand(i), where X is the number of users required to benefit to justify decreasing power, and where normSINRcand(i) is the normal SINR of the selected base station.
- a good SINR may be a value between 13 and 23 dB.
- FIG. 1 A- 1 C is a flowchart depicting a method for making a change in transmit power for a base station, in accordance with some embodiments.
- FIG. 1 shows the steps of the embodiments as they pertain to transmit power optimization for a single base station operating within a larger network. These steps show how a power determination can be made for this single base station while taking into account how the power settings and adjustments for that base station will affect other base stations within the network.
- IntDownMetric is filtered according to an infinite impulse response filter to derive the second metric.
- RSRQ may be used to assess signal quality.
- the RSRQ value from the UE measurement report may be used unchanged. This value is RSRQ serv .
- the reporting range of RSRQ values is between ⁇ 19.5 dB and ⁇ 3 dB.
- more than one UE measurement may be available, in which case measurements may be averaged, in some embodiments. This is because RSRQ measurements are heavily dependent on instantaneous traffic load, and thus should be averaged over a longer period when possible.
- the comparison is made between the RSRQ serv or a particular UE and a RSRQ threshold. If the value of RSRQ serv is above the threshold, there is no need to increase transmit power for this UE, and the loop continues to the next UE. If the value of RSRQ serv is not above the threshold, the signal is low and would benefit from increasing the transmit power. Execution continues to step 158 , where the RSRQ serv of this UE is mapped to a weighted integer. At step 160 , the integer is added to an integer value SINRUPMetric, which persists across loop iterations, and the next iteration of the loop is begun. SINRUPMetric corresponds to a count of UEs that would benefit from the increase in transmission power at the selected base station.
- step 168 corresponds to step 166 at FIG. 1 B .
- Step 170 begins a loop for calculating the fourth metric. The loop runs over all reporting UEs, and determines the consequences of decreasing the transmit power by PowerStepDown, as indicated at note 172 . Loop 170 includes steps 174 - 182 . Although it is not described in step 170 or step 174 , in some embodiments, UE RSRV measurements may be filtered, averaged, mapped using a lookup table, or otherwise adjusted prior to comparison with the thresholds described in step 174 .
- the RSRQ serv from the UE is compared with a threshold, RSRQThresholdDown, to determine whether the UE will be impacted by reducing the transmit power level of the selected base station by the amount powerStepDown. If RSRQ serv is less than RSRQThresholdDown, there is no need to use this UE in assessing the transmit power level, and this UE is ignored, as indicated at step 176 . If RSRQ serv is not less than RSRQThresholdDown, processing continues for this UE.
- step 178 the RSRQ serv is mapped to a weighted integer i, and at step 180 , integer i is added to SINRDownMetric, which persists through the loop. After all UE measurement reports are processed, the loop ends at step 182 . At step 184 , SINRDownMetric is filtered using an infinite response filter.
- Step 186 all four metrics have been calculated, and a final decision metric is calculated.
- One decision metric is used for making both the power up and power down decisions.
- the decision metric may be based on one, two, or three of the four metrics. In some embodiments, additional metrics may be provided. In some embodiments, weighting factors may be applied to the metrics to further adjust the operation of the system. In some embodiments, the positive/negative signs of the four metrics may all be positive and the metrics may be added. In some embodiments, the signs may be mixed, and the metrics may be added (resulting in some metrics being subtracted, as shown above).
- step 188 if the decision metric is greater than the decision threshold for increasing power, execution passes to step 190 , where transmit power is directed to be increased at the selected base station by powerStepUP. Otherwise, execution passes to step 192 .
- step 192 if instead the decision metric is below the decision threshold for decreasing power, execution is passed to step 194 , where transmit power is directed to be decreased at the selected base station by powerStepDown. Otherwise, execution continues at step 196 .
- step 196 it is determined that no transmit power adjustment is needed, and at step 198 , execution ends.
- a quiet period follows until execution is re-triggered based on a timer, in some embodiments.
- Incoming UE measurement reports are saved and associated by UE, by base station, and by time for later retrieval, so that the reports will be available during the next execution of this method.
- FIG. 2 is a schematic diagram showing an exemplary wireless network in accordance with some embodiments. Seven wireless networks 202 , 204 , 206 , 208 , 216 , 214 , and 212 are presented, each with a different coverage area shown by overlapping ovals. Each of the wireless networks is managed by management server 210 , and connected thereto by X 2 protocol links.
- some base stations may be eNodeBs. In some embodiments, some base stations may be small cells, macro cells, or micro cells. In some embodiments, the base stations may be multi-radio access technology (multi-RAT) base stations supporting EUTRAN, UTRAN, and other radio access technologies (e.g., 3G, 4G LTE, and Wi-Fi technologies).
- multi-RAT multi-radio access technology
- Management server 210 is connected to each of the cells, and receives and stores UE management reports from UEs attached to each cell.
- Network 204 does not have an overlapping coverage area with any network except for network 202 .
- Network 202 is at a distance 1 away from network 204 .
- network 204 is connected to the other networks.
- Management server 210 is aware of each of the cells.
- Network 212 is not coextensive with network 202 , but is connected via network 214 .
- FIG. 3 is a schematic diagram illustrating numerical ranges used to determine whether to make a change to transmit power, in accordance with some embodiments. If the sum of the four metrics is positive and therefore in the range 310 , the selected base station's transmit power may be increased. If the sum of the four metrics is negative and in the range 330 , the selected base station's transmit power may be decreased. If the sum of the metrics falls within a predetermined middle threshold 320 , no change may be needed.
- another method is provided for performing adjustment of transmit power at a network node.
- a particular base station serving a set of UEs, is selected.
- SINR signal to interference ratio
- a target SINR is compared with a target SINR. If the existing SINR is greater than, or greater than or equal to, the target SINR, in some embodiments, a determination is made to adjust the transmit power of the selected base station.
- the existing SINR may be computed per UE to obtain an individual SINR per UE, based on measurement reports, and then the individual SINR values per UE may be combined, either by averaging, summing, weighted summing, or another technique, in order to create a single existing SINR metric for comparison with the target SINR.
- FIGS. 4 A- 4 B together constitute an alternative flowchart depicting a method for making a change in transmit power for a base station, in accordance with some embodiments. Unless otherwise specified, the operations described in FIGS. 4 A- 4 B may occur on a network server, cloud server, core network server, aggregation server, or other server coupled to one or more base stations.
- n is the number of neighbors.
- a minimum SINR over all UEs served by the candidate base station (i.e., the lowest SINR of all SINRs obtained from the UEs served by the candidate base station) may be calculated, based on the results of step 412 .
- step 422 further decision metrics are calculated. Specifically, a candidate SINR metric, candSINRmetric, is calculated, taking into account the power increase value computed at step 420 for all UEs attached to the candidate base station.
- a candidate SINR metric candSINRmetric
- the metrics for each of these UEs calculated in step 424 may be combined to form a single metric, by averaging or by another method.
- This metric may be known as neiSINRmetric.
- the following formula may be used:
- step 418 is the entry point described above, which is executed when signal strength is sufficiently strong that no increase in transmission power is needed. However, it is possible that a decrease in signal power would result in a reduction of interference, in which case a decrease in signal power would be warranted even when an increase would not. Operation passes to step 432 .
- normSINRi ((newSINRi ⁇ oldSINRi)/oldSINRi);
- step 430 this step is reached only after it is concluded that transmission power will be changed.
- the power changes are committed to the network, by sending a signal to the candidate base station to change the power to a particular power level.
- previous UE measurements are also cleared from the system. This is because once the power levels have changed, new UE measurements reflecting the new state of the system are required.
