Embodiment
Below in conjunction with the accompanying drawing in the present embodiment, the technical scheme in the present embodiment is clearly and completely described,
Obviously, described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based in the present invention
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of protection of the invention.
A kind of network resource configuration method is present embodiments provided, this method is related to a kind of ABS configurations frame, ABS configurations
Frame is used for macro base station configuration cell downlink subframe and scheduling user, and ABS configuration frames include variable subframe.ABS configuration frames
Frame structure is as shown in Figure 1.
As shown in Figure 1,8 subframes are included in the ABS configuration frames in the present embodiment, 8 subframes can sum up
For following three types：Dominant Normal (profiling non-ABS), Dominant ABS (profiling ABS), Optional
Subframe (variable subframe).Wherein, when subframe type is profiling non-ABS subframes, macro base station is launched with full power；Group
When frame type is profiling ABS subframes, macro base station subtracts power or silence；When subframe type is variable subframe, born according to cell
Carry to judge that the subframe is ABS or non-ABS.
ABS configurations frame of the prior art only includes non-ABS subframes and the two kinds of subframe of ABS subframes,
And the ratio of ABS subframes is fixed, an ABS configures frame except including profiling non-ABS subframes and profiling ABS in the present embodiment
Outside frame, in addition to variable subframe, the variable subframe can be arranged to profiling ABS subframes or profiling according to the workload-adaptability of cell
Non-ABS subframes, thus the ratio of the ABS subframes in an ABS configuration frame is dynamic change.
As shown in Fig. 2 each variable subframe in the ABS configuration frames of current area is entered in the method that the present embodiment provides
Row operations described below：
S201：At the time of the current variable subframe of acquisition corresponds to, grand user load quantity and cell range extension CRE in cell
User load quantity.
As stated in the Background Art, LTE-Advanced employs heterogeneous network technologies, thus existing grand in the network structure
Base station, there is micro-base station again.Then, CRE user refers in LTE-Advanced networks, as a result of CRE technologies so that part
The user originally belonged under macro base station coverage accesses micro-base station, and this certain customers is CRE user.Specifically, CRE skills
Art refers to, Reference Signal Received Power (the Reference Signal Received from micro-base station for allowing UE to receive
Power, RSRP) certain bias is added, then compared with the RSRP of the macro base station received, if the former is big, portion
Divide grand user to access micro-base station, turn into the CRE user of Microcell.
S202：According to grand user load quantity and CRE user loads quantity by current variable subframe be defined as ABS subframes or
Person's non-ABS subframes.
The purpose of setting of current variable subframe is the ratio that ABS subframes are adjusted according to current macro cell number of users dynamic,
And then cause macro base station to adjust transmission power according to ABS sub-frame configurations ratio, realize and dynamically carry out resource distribution for grand user.
S203：The transmission power of macro base station is adjusted according to the subframe type of determination.
If grand user load quantity is more, current variable subframe is defined as non-ABS subframes, macro base station is with normal work(
Rate is launched, to cause macro base station to provide preferable service as grand user.
If CRE user load quantity is more, current variable subframe is defined as ABS subframes, macro base station adjustment power enters
Row transmitting, to reduce interference of the macro base station to CRE user.
Further, step S203 is specifically included：
If it is determined that current variable subframe is ABS subframes, then the transmission power for adjusting macro base station is predetermined power value.
In a kind of implementation of the present embodiment, the predetermined power value is zero, i.e. macro base station silence or dormancy (macro base station
Do not launch any power), macro base station silence can reduce the interference to CRE user, improve the handling capacity and system energy of CRE user
Effect.
When the transmission power of macro base station is higher, macro base station edge user throughput is larger, but throughput of system is smaller
And system energy consumption is larger, therefore system energy efficiency is relatively low；Conversely, macro base station edge user throughput is smaller, system energy efficiency is higher.In order to
A compromise is taken between macro base station edge user throughput and system energy efficiency, the present embodiment introduces the thought of game theory, optimization
The transmission power of each macro base station during each ABS subframes.Thus, in another implementation of the present embodiment, currently may be used
When becoming subframe as ABS subframes, macro base station is launched according to predetermined power value, and the predetermined power value is not zero, and its computational methods is as follows：
Utility function U value is calculated according to preset formula, it is grand small by i-th when the utility function U takes maximum
The transmission power of j-th of Microcell in areaIt is defined as the predetermined power value.
Wherein, the preset formula is：
In the formula, X is the Hong Yonghuji of i-th of macrocell,It is the bandwidth of x-th of grand user in the cell,
It is the signal to noise ratio of x-th of grand user,It is the handling capacity of x-th of grand user,It is
The handling capacity of all grand users of i macrocell；Similarly,It is all Microcells use of i-th of macrocell
The handling capacity at family.
It is the power consumption of i-th of macrocell,It is the power consumption of all Microcells of i-th of macrocell, Pin
It is the function relevant with transmission power, it is contemplated that the power consumption of transmitting antenna, cell load etc..
The independent variable of the optimization problem, i.e., the transmission power of j-th of Microcell of i-th macrocell；It is xth
The signal to noise ratio of individual grand user,It is the power consumption of i-th of macrocell, XeIt is the Hong Bianyuanyonghuji of i-th of macrocell,It is xtheThe signal to noise ratio of individual grand edge customer.
It is the signal to noise ratio of y-th of Microcell user,It is the power consumption of all Microcells in i-th of macrocell, this
Both with the transmission power p of MicrocellPRelevant variable, and withIt is unrelated；Positive coefficient α is a regulatory factor, is used for
Adjust the balance between system energy efficiency and grand edge user throughput.By calculating, the power for making utility function U values maximum takes
Value, as transmission power of the macro base station in ABS subframes.
If it is determined that the current variable subframe is non-ABS subframes, then the transmission power for adjusting the macro base station is normal
Performance number.
Signified normal power value just refer to base station to user normally send data when performance number, generally 43dBm.
In the network resource configuration method that the present embodiment provides, and in the prior art, all cells under macro base station covering
All be configured with identical, the ABS ratios of fixation are compared, macro base station for each cell carry out resource allocation when, first obtain work as
Preceding variable subframe corresponds to the moment, and grand user load quantity and cell range extend CRE user load quantity in cell, further according to grand
Current variable subframe is defined as ABS subframes or non-ABS subframes by user load quantity and CRE user loads quantity, finally
The transmission power of macro base station is adjusted further according to obtained subframe type (ABS subframes or non-ABS subframes).Due to
