A detailed description of the preferred options for the implementation of
To make the objectives, technical solutions and advantages of the present invention is more understandable, technical solutions provided in the present invention, further describes in detail with reference to the options for implementation and accompanying drawings.
Figure 1 - block diagram of the sequence of operations ways to install the shift channel power in accordance with the embodiment of the present invention. As shown in figure 1, the method may include:
101: receiving load cell, providing coverage of a base station.
Load cell can be obtained through a pre-established period of time block of resource utilization (RB), or historical average volume of traffic honeycomb, with pre-established period of time can be set in accordance with the actual conditions and actual demands, and may be, for example, day or week.
The historical average traffic volume statistical information obtained through the collection of statistics on the volume of traffic a cell in the pre-set period of time. For example, after the statistics gathered during the week, it is known that the historical average volume of traffic to a particular cell is less than 200 times/hour from 1:00 to 4:00 each day, which indicates that during this period of time downloading cell weak.
RB - minimum transfer unit in the system of LTE, and one RB usually can include 12 consecutive carriers. Sub-carrier frequency - the minimum frequency resource in the system LTE, and bandwidth is the current subcarrier usually - 15 KHz, and bandwidth assigned to the user equipment (UE) a multiple of the block of the resource. Therefore, the bandwidth of the UE depends on the number of RB.
The availability of the unit of resource is a key indicator for measuring the load cell, but the download cell usually ranges. In order to reflect the long-term trend changes load cells, in addition, the embodiment of the present invention can be achieved by using the following method to obtain coefficient of the use of RB to reflect the load cell more precisely: the coefficient of utilization of RB cell, process filtration on the utilization rate of the RB and use the received after processing filtering value as a block of resource utilization cell to measure the load cell. In particular, a way to get the block of resource utilization cell is described with reference to the following example.
The average value of the coefficient of the use of RB in each time interval transmission (TTI) is obtained in each period T cell_RB time. TTI can be 2 MS or 10 MS or some other value. In each TTI utilization factor RB can be obtained by calculating the ratio of the number of used RB to the total number of RB downlink.
On the average value of the coefficient of use of RB filtering is performed using the following expression (1).
η cell_RB (i)=a cell_RB η cell_RB (i-1)+(1-a cell_RB )η(i) (1)
In the expression, n cell_RB (i) the value obtained after processing-filtration, fulfilled on an average ratio of RB cell, resulting in the calculation i, and is used to reflect the load cell. The embodiment of the present invention filtering is done using the filtering system, so α cell_RB
specifies the filter, and η(i) indicates the average value of the coefficient of use of RB obtained in the calculation of the i.
It should be noted that, although the above-mentioned system of filtration involved in this embodiment of the present invention can also be used other means of filtering to filter the short-term fluctuation bursts in some TTI.
102: Comparison of obtained download cell base station coverage with a pre-defined threshold value and setting the value to shift channel power UE in a cell in accordance with the result of the comparison.
For example, when the load cell is less than the preset threshold, this indicates that at this time weak download cell and shift value channel power UE in a cell can be reduced. When the load cell more than a preset threshold, the value of the shift channel power UE in a cell can be increased, for example, the value of the shift capacity of the channel is set to a value less than 0 to the value 0.
In particular, the value of shift channel power all UE in a cell can be set to the same value (i.e., level regulation cell), or the value of shift channel power part or all of the UE in a cell can be set in accordance with the priorities or the requirements of the power transmitting user equipments (i.e. regulation user level).
In addition, the regulation on the user level for different UE can be set different values of the shear power of the channel or the same value shift channel power. For example, in accordance with the priorities of the UE shift value channel power UE priority to meet a specific condition can only be modified, when the initial value of the shift of the channel power of another UE remains unchanged. Or, in accordance with the priorities of the UE, UE with different priorities are set different values of the shear power of the channel, for example, when the value of shift channel power must be reduced, because a reduction in the value of shift channel power leads to a decrease in bandwidth, the value of the shift channel power UE low priority can be reduced only so that the energy consumption of the base station has decreased, but to the extent possible, avoid degradation of throughput UE high priority. Or, in accordance with the required power transmission equipments UE, it changes the value of the shift of power channel only UE with the required transmission power satisfying a certain condition and the initial value of the shift channel power other UE remains unchanged. Or, in accordance with the required transmission power UE, the value of shift channel power are changed to different values than in accordance with differing levels of power required. That is, to set the values of channel power users in the cell can be implemented differential treatment to full energy consumption of the base station dropped, while the required throughput characteristics UE high priority can be secured preferable.
Shift value channel power - parameter setting for the PDSCH cell and used to indicate transmission of power used by the channel. The LTE system for temporary area and frequency domain is activated in adaptive modulation and coding (AMC), and for downlink activated multiplex technology orthogonal frequency distribution (OFDM). Therefore, the physical resource her downlink determined in accordance with sub-carrier OFDM and the period of the OFDM symbol, that is, a resource element (RE). Block resource can include 84 of the resource element.
PDSCH - channel downlink, where data from the base station is transmitted UE in a cell and through control of power transmission PDSCH can be adjusted energy consumption of the base station. In the protocols related to LTE technology, due to that the range of values of P A- [-6, -4,77, -3, -1,77, 0, 1, 2, 3] includes eight values. In other systems, such as high-speed system for packet access, in the aforementioned P A there may also be other ranges, which are not limited to the present invention.
In the way described in this embodiment, the value of the shift channel power is established in accordance with the state of the load cell, thus allowing flexible installation and dynamic adjustment of P A .
Figure 2 - block diagram of the sequence of operations ways to install the shift channel power in accordance with another embodiment of the present invention. As shown in figure 2, based on the method shown in figure 1, the method in accordance with the embodiment of the present invention additionally includes the following stage:
103: In accordance with the established shift value channel power control power transmission physical shared channel downlink cell.
In particular, when running the regulation at the level of cells, power transmission physical shared channel downlink all user equipments in a cell of control that this value is the same. When you regulation at the level of the user, control the transmission power of all or part of the users in the cell, namely, the transmission power of physical shared channel downlink custom control equipments that this value is the same as, or different in accordance with the priorities or the required transmission power.
In a pass-band downlink PDSCH power reference signal is constant. Consequently, since the P A set is installed and power transmission PDSCH and, the higher the value of R , the higher transmission power.
By setting the values of R , the base station receives the ability to reassign different modulation and coding scheme (MCS) for each regulated UE, thereby changing the use of RB and besides, respectively changing consumption of power resources, to achieve the flexible regulation of energy consumption.
In accordance with one aspect, when the loading specifies that the load cell is small, the transmission power of PDSCH can be reduced by setting the values of R And shift power channel so that the unoccupied RB were used to transmit the data as much as possible, thereby reducing energy consumption.
For example, as shown in figure 3, the coefficient of utilization RB current cell is 50%, P A all UE set to 0. After adjusting the value of P is reduced to A-3. It is assumed that the average index of MCS each UE in the cell is reduced to 15. Then, if the overall speed of the code equipments UE remains unchanged, the coefficient of utilization RB increases by 50% to 100%, which is equivalent to the fact that bandwidth (BW) channel increases by 50% to 100% compared to what it was before adjustment, and, at the same time, energy consumption is reduced by 25%. You can see that the embodiment of the present invention, lowering power consumption is achieved due to the consumption of resources RB. However, the option of the implementation of the present invention is realized only when the load cell is small. Is possible and desirable to achieve a decrease in power consumption due to the consumption of resources RB, because in this time a lot of resources RB are redundant and are idle.
To avoid ping- switch during the installation shift channel power in another embodiment of the present invention provides a method to install the shear power of the channel. As shown in figure 4, the method may include:
201: Receiving load cell, providing coverage of a base station.
At this stage, to describe the way in which load cell, providing coverage of a base station, you can use the link on the description in the embodiment shown in figure 1, the times described in detail in this document.
202: If the load cell is smaller than the first pre-set threshold, set the value of the shift channel power in the first value.
For example, loading can be coefficient of utilization of RB and we can assume that the first pre-defined threshold is 10%. When the occupancy RB less than 10%, this indicates that at this point in time weak download cell and shift value channel power (that is, P (A ) is established in -3 in the above range of values of the P A .
203: If the load cell is greater than the second preconfigured threshold, and less than a third of pre-defined threshold, the set value of the shift in power channel during the second value.
For example, suppose that another pre-defined threshold of 30%, the third pre-set threshold value of 50%. When the occupancy RB more than 30% and less than 50%, this indicates that at present, reasonable load cell, and the value of P is A set -1,77 in the above range of values of the P A , that is, in the second values. The second value is greater than the first value.
204: If the load increases from the value less than the first preconfigured threshold to a value larger than the first pre the threshold, and less than a second pre-defined threshold, the value of the shift channel power remains unchanged, in the first sense.
205: If the load decreases from more than a second a preconfigured threshold to a value less than the second preconfigured threshold and larger than the first pre-defined threshold, the value of the shift channel power remains unchanged, the second argument.
206: If downloading is increased from a value greater than the second preset the threshold to a value greater than the third preconfigured threshold and less than a fourth pre-defined threshold, the value of the shift channel power remains unchanged, the second argument.
For example, suppose that the fourth preconfigured threshold of 70%. When the occupancy RB constantly more than 70%, this indicates that at this point in time load cell is great, and the value of P is A not regulated in order to avoid further increase the use of RB and more intense loading and thereby impact on the processing capabilities of the services.
If the ratio of the use of RB increases from 50% to 60%, but not exceeding the fourth preconfigured threshold (70%), the value may remain unchanged in the second value. When the occupancy RB more than 70%, the value of P A can be adjusted to a value greater than the second value, such as 0 or a value greater than 0.
In this embodiment, in each of the above stages, the first pre-defined threshold of less than (<) the second pre-set threshold values less than (<) the third pre-set threshold values less than (<) the fourth pre-set threshold value, and the first value is less than (<) to the second value.
207: In accordance with the established shift value channel power set the transmission power of physical shared channel downlink cell.
For example, when the load cell, specified through use ratio RB - 5%, which is less than the first pre-defined threshold of 10%, P A set-3. After that, if the rate of use of RB increases, suppose that the coefficient of utilization of RB become - 20%at this moment in time P A may remain unchanged (-3). The value of P is A not regulated, while the coefficient of utilization of RB no more than the second threshold. Thus, we can avoid the chaotic establish the value of P A and phenomena ping- decision. Similarly, when the load cell, specified through use ratio RB - 35%, in accordance with the above method the present invention P A set -1,77. After that, if the rate of use of RB decreases, suppose that the coefficient of utilization of RB changed to 20%at this moment in time P A may remain unchanged (-1,77) and the value of P is A not regulated, while the coefficient of utilization of RB no less than the first threshold.
It should be noted that in this version, the implementation of the first pre-defined threshold, the second pre-defined threshold, the third preconfigured threshold and fourth preconfigured threshold is taken as an example to describe that way under variant of the implementation of the present invention, in reality, is not limited, and values, and the number of thresholds can also be set in accordance with actual requirements.
5 is a schematic block diagram of the device to install the channel power in accordance with the present invention. Device 10 for installation channel power may include block 11 of obtaining and block 12 to set a parameter.
Block 11 of receipt receives load cell, providing coverage of a base station. Block 12 installation parameter compares the obtained via a block 11 of receipt of booting from a pre-defined threshold value and sets the value of the shift channel power P A user equipment in the cell, in accordance with the result of the comparison. For example, when the load cell is less than the preset threshold, this indicates that at this time of the load cell is small and the value of the shift channel power UE in a cell can be reduced; when the load cell more than a preset threshold, the value of the shift channel power UE in a cell can be increased, for example, the value of the shift channel power adjustable from values less than 0, 0. In particular, the block 12 installation option can set a value shift channel power all user equipments in a cell of the same value, to implement the regulation at the level of cells, or set the value of shift channel power of all or part of the user equipments in a cell in accordance with the priorities or the required transmission power user equipments in the cell, in order to implement regulation on the user level.
It should be noted that for the description of the methods of operation of each unit in the base station in this embodiment, you can use the link on the description in the variants of the method, not once described in detail in this document.
In this variant of the implementation of the value of the shift in power channel can be flexibly installed in accordance with the state of the load cell.
In addition, in order to avoid ping- effect may be pre-installed numerous thresholds, for example, the first pre-defined threshold, the second a preconfigured threshold, the third preconfigured threshold and fourth preconfigured threshold, with a first pre-set threshold, less than (<) the second pre-set threshold values less than (<) the third pre-set threshold values less than (<) the fourth pre-set threshold value, and the first value is less than (<) to the second value.
If the download obtained by means of block 11 of receipt, less than the first pre-defined threshold, the value of the shift capacity of the channel is set to the first value less than the current value of the shift in power channel; if the load cell is greater than the second preconfigured threshold, and less than a third of pre-defined threshold, the value of the shift in power channel is set on the second value less than the current value of the shift in power channel; if the load increases from the value less than the first pre-set threshold to a value larger than the first pre-set threshold, and less than a second pre-defined threshold, the value of the shift channel power remains unchanged, in the first sense; if the load decreases from more than a second a preconfigured threshold to a value less than the second preconfigured threshold and larger than the first pre-defined threshold, the value of the shift channel power remains unchanged, in the second value; if the load increases from values larger than the second preconfigured threshold to a value greater than the third preconfigured threshold and less than a fourth pre-defined threshold, the value of the shift channel power remains unchanged, the second argument.
Phenomena ping- decision can be avoided by installing multiple thresholds, that is, the phenomenon of chaotic establish the value of P A in decision-making can be avoided. For a description of how to avoid the phenomenon of ping- decision, you can use the link on the previous variants of the method, not once described in detail in this document.
It should be noted that in this version, the implementation of the first pre-defined threshold, the second pre-defined threshold, the third preconfigured threshold and fourth preconfigured threshold is taken as an example to describe that way under variant of the implementation of the present invention, in reality, is not limited, and values, and the number of thresholds can also be set in accordance with actual requirements.
In addition, the above load in a particular case may be block of resource utilization honeycomb or historical average volume of traffic cell. When they receive the availability of the unit of the resource block 11 of receipt of may in a particular case include module 11A receipt and module 11B filtering, as shown in Figure 6.
When the block is used, the resource is retrieved, the first module 11A receive receives the coefficient of using RB-comb, and then the module 11B filter handles filtering on the utilization rate of the RB received via the module 11A receipt to get the filtered value of the coefficient of using the resource, which is used as the boot. To describe a particular way of filtering you can use the link on the description of the expressions (1) in the above embodiment, not once in detail described in this document.
By processing filtering originally received the ratio of unit resource, you can avoid errors caused by fluctuations of the load cell, and thus more accurately reflect the long-term trend changes load cell.
