Description
Technical field
The present invention relates to the communications field, more particularly to a kind of method and device of base station energy-saving control.
Background technology
In mobile communication system, in order to improve frequency efficiency, the capacity of system is increased, usually using frequency
Rate multiplexing technology.Channeling refers to after separated by a distance, in given overlay area, to exist
Many cells using same class frequency, these cells are referred to as co-frequency cell, and there is neighbour between co-frequency cell
Disturb in area.
In Long Term Evolution (LTE) specification, third generation partner program (3GPP) allows number of mechanisms
Adjacent area is avoided to disturb, such as Inter-Cell Interference Coordination (ICIC) and collaboration multicast communication (CoMP).
Wherein, uses of the ICIC to Radio Resource in each cell in the way of inter-cell coordination is limited,
Be can use including limiting which running time-frequency resource, or its transmission power is limited on certain running time-frequency resource.Also
It is to say, ICIC is limited by carrying out certain to an available resources for cell, so as to improve neighbor cell exist
Signal to Interference plus Noise Ratio (SINR) in these resources, improves the data rate of cell edge, improves
The business experience of edge customer.
According to cell-to-cell information interaction frequency, ICIC can be divided into the static ICIC that evades in advance and control afterwards
The dynamic I CIC of system.It is soft multiple that wherein static state ICIC can be divided into frequency according to the extent for multiplexing of edge band again
With (Soft Frequency Reuse, SFR) and partial frequency multiplexing (Fractional Frequency Reuse,
FFR), purpose is the frequency duplex factor as one for improving cell edge, improves the performance of cell edge, is reduced
The interference of minizone.But the mode evaded is only applicable to the scene of cell edge underload, works as cell in advance
When edge load is higher, the resource that each Cell Edge User takes is more, and substantially no free time is available for spirit
The running time-frequency resource of scheduling living, the mode evaded in advance is not just applied to.
The ICIC for controlling afterwards by interacting load information between the base stations, understand adjacent area resource use with
And disturbed condition；When user equipment (UE) of this cell is dispatched, or avoid what adjacent area had used
Radio bearer (RB), or transmit power is reduced on these RB, while the utilization of resources feelings of oneself
Condition tells adjacent area, and the resource collision of neighboring interval is avoided as far as possible to reach the purpose of interference coordination.
The ICIC for controlling information exchanges between the base stations afterwards in, it is divided to two kinds of up-link and downlink
Situation.In the downlink, a position for being Relative Narrowband TX Power (RNTP) is defined on interface
Unit's figure, to reduce interfering for different districts downlink.Each bit of RNTP represents frequency domain
On a RB, therefore this bit can tell neighbor cell, " I has used this RB, if
You also use this RB, please reduce its transmission power." in up-link, LTE defines two message
Overload indicate (OI) and high interference instruction (HII), with help reduce different districts up-link it is mutual
Interference.After each ICIC cycle, base station can send interference information to neighbor cell.Generally, ICIC weeks
Phase (usual tens to hundreds of milliseconds) is longer than dispatching cycle (TTI, 1ms).
Enhanced coordinating district interference (eICIC) introduces almost blank subframe (ABS) in the time domain
Concept realizes the Coordination Treatment of time domain, reduces the annoyance level of minizone.ABS only must comprising some
The signal wanted, and transmission power is than relatively low.EICIC is being done by configuring ABS in interfered cell
Disturb and use in cell these ABS come to be provided business by more strongly disturbing user, it is small so as to avoid
Interval interference problem；Its core concept is the client in grand Microcell intersection, special at some by femto base station
Service is provided in fixed subframe, and macro base station does not transmit user data in these specific sub-frames (ABS),
To reduce the interference to femto base station.
CoMP refers to being disturbed by cooperateing with treatment between different base station, or avoids interference, or will be dry
Disturb and be converted into useful signal, it uses the channel condition information (CSI) reported from UE, utilization space letter
Difference on road carries out signal transmission, is multi-input multi-output system (MIMO) technology under multiple cell
Application.
At present, access network energy consumption has accounted for the overwhelming majority of whole communication network energy consumption, is that GreenNet is most needed
The part of concern.Current power-saving technology can be divided three classes：One is device level energy-conservation, preferably low-power consumption device
Part, and in the low-power consumption mode of the reasonable application device of business idle periods, improve efficiency of device such as power amplifier etc.；
Two is device level energy-conservation, it is considered to 2/3/4G/WLAN system business load tide effect in the time, spatially
Should, provide the different grain sizes such as symbol, time slot, passage, carrier frequency, flexible pass for different application scenarios
Disconnected control strategy；Three is network level energy-conservation, for the features of 2/3/4G/WLAN systems, is realized
Cooperation energy-saving between wlan network and Cellular Networks.
In the class power-saving technology of the above three, for device level equipment power-saving technology application as a lot, such as
Efficiency power amplifier is improved, current conversion efficiency is improved and reduces air conditioner in machine room and powered, the development of its technology
Restricted by material, later stage Improvement is limited, therefore, current focus is device level and network level energy-conservation.
The conservation measures of device level mainly has carrier wave to turn off, symbol is turned off and passage is turned off etc., and implementation is led to
It is often that equipment activates power saving function automatically when being less than certain threshold value in load certainly, when load is higher than certain door
Automatic during limit value to deactivate power saving function, activation and deactivation are all negative according to what is be pre-configured with by equipment itself
Carry threshold value determine, do not loaded by adjacent base station, energy-conservation configuration etc. influence.
Symbol shut-off refers to that, when traffic loads are low, base station accords with partial orthogonality frequency division multiplexing (OFDM)
When number not having data is activation, power amplifier is closed in base station in the symbol period of these " without data is activations ", so that
System power dissipation is reduced, base station discontinuous transmission (DTX) power-saving technology is also called.Different from interference coordination skill
The technology of the reduction RB transmission powers in art, what symbol shut-off was closed is the whole of certain OFDM symbol
The electromagnetic signal of frequency domain, closing be this hardware of power amplifier grid voltage, power amplification after closing
Not only transmission power is zero to device in this OFDM symbol, and its own power consumption is also very low.
Passage shut-off refers to the base station close portion point transmission channel, so as to reach energy-conservation when traffic loads are low
Effect.In general, what passage shut-off was closed is the power amplifier and radio frequency on this transmission channel
Circuit.
Carrier wave shut-off is applied under multicarrier scene, and one of carrier wave provides basic covering, is basic covering
Cell；Remaining carrier wave provides capacity enhancing, is energy-saving cell.When function is opened, by software to cell
Physics infinitely carries (PRB) occupancy and carries out periodicity monitoring, within the given idle time period, if
PRB occupancies are less than configured threshold and certain time, then capacity layer user is just switched to covering
Cell, capacity cell closes state of activation, only retains coating, can so reduce antenna transmission power,
So as to reach the purpose of energy-conservation；And work as the lifting of PRB occupancies and exceed pre-determined threshold, and continue a timing
Between, or the time is beyond the idle time period of configuration, then reawake capacity cell, receives customer service.
Wherein, what carrier wave shut-off was closed is the reference signal on carrier wave, with 8 hours of typical busy hour load, in
Deng 10 hours of load, 6 hours of idle load.By taking the passage macro base station networkings of F+D 8 as an example, in the spare time
When economizer stage, cell close before and after its power consumption be respectively 250 watts and 100 watts, whole day can be saved
6*150=0.9 degree electricity, can save 60% energy consumption during shut-off, whole day can save 10% energy consumption.
The energy-conservation of network level is mainly under the scene of small area overlapping covering, by activating small base in low-load
Stand sleep mode, make whole station that the purpose of power saving is reached into low-power consumption mode.
However, the Energy Saving Strategy of existing device level and network level is all only according to base station own load and neighbour
Area is loaded to judge whether base station activates its power saving function, and each base station is not examined when power saving function is performed
Consider the power saving function and concrete configuration of its adjacent base station use, be so possible to employing identical energy-conservation
Identical unit is closed between the adjacent base station of function (such as：In symbol turn-off function, closed in radio frames
The subframe of same position is closed).If but in fact, can effectively control close unit position,
The interference between adjacent area can effectively be reduced, the handling capacity of network is lifted.
