Embodiment

For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.

Base station mainly comprises base band, radio frequency, power amplifier, antenna, heat radiation and six parts of power supply, as shown in Figure 1.Baseband portion mainly completes the signal works for the treatment of such as modulating/demodulating, coding/decoding, mapping/demapping; The amplification of the main settling signal of power amplifier; The radio frequency of narrow sense refers to RF small signals, and the radio frequency of broad sense refers to whole piece radio frequency link, comprises power amplifier.In dissimilar base station, the accounting of each device on base station power consumption is all not identical.For example, in macro base station, power amplifier occupies main energy consumption, and in micro-base station and femto base station, base band is occupied main energy consumption; In little base station, power amplifier and base band are all occupied larger energy consumption.In addition, the variation of traffic carrying capacity is also different on the impact of dissimilar base station, and the power consumption of macro base station and little base station enlarges markedly along with the rising of traffic carrying capacity, and the power consumption of micro-base station and femto base station changes along with the rising of traffic carrying capacity not quite.

As shown in Figure 2, base band mainly comprises seven parts: sampling and filtration module, forward error correction coding module, Fourier transform and OFDM(Orthogonal Frequency Division Multiplexing, OFDM) processing module, frequency domain processing module (mapping/demapping and balance module), digital pre-distortion processing module, processor, to the serial link of backbone network.The report of European Union's green communications research project shows, base band power with and accounting in base station power in different base station type, alter a great deal; When full load, single antenna corresponding base band power in different base station type is as shown in table 1; Wherein, within 2010,2012, represent respectively the data corresponding to base station of new production in 2010,2012.

Table 1

On hardware is realized, each base station comprises multiple baseband boards, and every baseband board comprises multiple chips, and each chip comprises multiple modules (or being referred to as processing unit); Wherein, the module in baseband board, chip and chip is referred to as device.Therefore, baseband board turn-offs and chip shutoff relatively, and module shuts down is the thinner power save mode of granularity.In addition, turn-off for the device that can realize power remove, refer to power remove; For the device that only can realize clock shutoff, refer to that clock turn-offs.

The power-saving technology of turn-offing based on baseband board: be applied to the base station that comprises master control veneer and base band veneer, the number of users of every base band veneer of master control veneer statistics, if the actual number of users using is less on certain base band veneer, the user on this veneer is switched to other above veneer, it is dormancy or off-position that this veneer is set.In distributed base station, can realize the integration of business and scheduling between multiple baseband boards in BBU, make as far as possible carrier wave and baseband board enter or be in off state, reduce the energy consumption of BBU.Energy-conservation gain: the power consumption (energy consumption of that piece plank of turning off, although other plank traffic carrying capacity increases, power changes little, because the power consumption of BBP changes very little with traffic carrying capacity) of an about BBP plate; In macro base station, approximately 30w.

The power-saving technology of turn-offing based on chip: be applied in the base station of the baseband board that comprises multiple parallel processing chips.First estimate total demand of processing quantity by master control borad, obtain the chip-count of current needs, then judging whether current in running order number of chips exceedes estimates the number of chips obtaining, if the chip-count in reality exceedes required chip-count, by the unnecessary process chip power-off on baseband board or enter resting state.Method of adjustment is that the user on chip less total number of users is migrated on other chips, and ensures that the load in other process chip is no more than predefined thresholding, after adjustment, closes idle chip.Energy-conservation gain is approximately the power consumption of a chip, 10w left and right.

The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.

The technique effect that the present invention produces for convenience of description, please refer to following formula and data:

The distributed base station (BTS:Base Transceiver Station) of extensive use is at present mainly by BBU(Base Band Unit, baseband processing unit) and RRU(Radio Remote Unit, Remote Radio Unit) composition, the wherein Base-Band Processing part in BBU corresponding diagram 1, RRU comprises radio frequency, power amplifier and the antenna in Fig. 1, and its power consumption calculation formula is as follows:

P_{BTS} = Σ_{i = 1}^{M} P_{{BBU}_{i}} + Σ_{j = 1}^{N} P_{{RRU}_{j}} + P_{overhead} = Σ_{i = 1}^{M} P_{{BBU}_{i}} + Σ_{j = 1}^{N} \frac{P_{static}^{{RRU}_{j}} + Σ_{k = 1}^{{AN}_{j}} \frac{P_{{out}_{k}}^{{RRU}_{j}}}{α (P_{{out}_{k}}^{{RRU}_{j}})}}{η_{DCDC}^{{RRU}_{j}}} + P_{overhead \cdot \cdot \cdot (1)}

Wherein, M, N represent respectively the number of BBU, the number of RRU; p _overheadrepresent respectively power, a j RRU of i BBU power, base station remainder power or be called overhead; AN _jrepresent j the antenna number on RRU; represent respectively the static power of j RRU, the DC power supply conversion efficiency of a j RRU, the power output of the j upper k root of a RRU antenna; represent that j the corresponding power amplifier of the upper k root of RRU antenna in power output is time efficiency; If there are 1 BBU and 3 RRU in certain base station, on each RRU, all there are 2 antennas, that is: M=1, N=3, AN _j=2, j=1,2,3.Under certain traffic carrying capacity, the power consumption data of each device is as follows:

the power of BBU is 100 watts;

P _overhead=50watt: the power of base station remainder is 50 watts;

the static power of each RRU is 80 watts;

the DC power supply conversion efficiency of each RRU is 90%;

the power output of the upper every antenna of each RRU is 15 watts;

the efficiency that the power amplifier that the upper every antenna of each RRU is corresponding is 15 watt-hours in power output is 30%;

So according to formula (1), can obtain the power of this base station in the time of current business amount and be:

P_{BTS} = P_{{BBU}_{1}} + Σ_{j = 1}^{3} \frac{P_{static}^{{RRU}_{j}} + Σ_{k = 1}^{2} \frac{P_{{out}_{k}}^{{RRU}_{j}}}{α (P_{{out}_{k}}^{{RRU}_{j}})}}{η_{DCDC}^{{RRU}_{j}}} + P_{overhead} = 100 + Σ_{j = 1}^{3} \frac{80 + Σ_{k = 1}^{2} \frac{15}{0.3}}{0.9} + 50 = 750 watt \cdot \cdot \cdot (2)

Suppose that after the base station processing scheme that provides of the application embodiment of the present invention,, under equal traffic carrying capacity, the power down ratio of BBU is that the power of the so whole base station of x will be reduced to:

P_{BTS}^{New} = Σ_{i = 1}^{M} (P_{{BBU}_{i}} (1 - x)) + Σ_{j = 1}^{N} \frac{P_{static}^{{RRU}_{j}} + Σ_{k = 1}^{{AN}_{j}} \frac{P_{{out}_{k}}^{{RRU}_{j}}}{α (P_{{out}_{k}}^{{RRU}_{j}})}}{η_{DCDC}^{{RRU}_{j}}} + P_{overhead} \cdot \cdot \cdot (3)

Tentation data substitution formula (3) in wushu (2), can obtain

P_{BTS}^{New} = 100 (1 - x) + Σ_{j = 1}^{3} \frac{80 + Σ_{k = 1}^{2} \frac{15}{0.3}}{0.9} + 50 \cdot \cdot \cdot (4)

= 100 (1 - x) + \frac{1000}{3} + 50 + \frac{800}{3}

According to formula (4), we can draw the variation relation of base station power with base band power, as shown in Figure 6.As can be seen from Figure 6, base station power reduces along with the reduction of the power of eating dishes without rice or wine, base band power and overhead, and wherein, when base band power declines 50% time, base station power is by declining 50W;

The formula of the energy-conservation gain of calculation base station as the formula (5)

EnergySavingGain = \frac{P_{BTS} - P_{BTS}^{New}}{P_{BTS}} \cdot \cdot \cdot (5)

Formula (2) and formula (4) substitution formula (5) are obtained,

EnergySavingGain = 1 - [100 (1 - x) + \frac{1000}{3} + 50 + \frac{800}{3}] / 750 \cdot \cdot \cdot (6)

According to formula (6), we can draw the relation between energy-conservation gain and the down ratio of base band power of base station, as shown in Figure 7.As can be seen from Figure 7, the energy-conservation gain of base station raises along with the increase of the power down ratio of eating dishes without rice or wine, and wherein, when base band power declines 50% time, the energy-conservation gain of base station is 6.67%.

It is worth mentioning that, energy efficiency and spectrum efficiency are two important indicators that following green communications system is paid close attention to, and wherein, energy efficiency refers to the throughput of system under unit energy, and system peak transfer rate under the spectrum efficiency unit of referring to frequency spectrum.With regard to the Base-Band Processing scheme proposing with regard to the embodiment of the present invention, device closes has no progeny, and the energy that base station consumes has reduced, and the throughput of base station does not change with the frequency spectrum taking, and therefore, has improved energy efficiency, and spectrum efficiency is not affected.
