The bandwidth of cell of standard.
And in the application of reality, the bandwidth that operator is possessed may not be standard bandwidth.In order to make
With LTE network, operator has to using the standard bandwidth less than its own bandwidth.For example, certain fortune
Battalion business possesses the bandwidth of 12MHz, and finally the operator can only use the standard bandwidth of 10MHz, remaining
2MHz bandwidth causes the waste of frequency spectrum resource.
Using existing technology, there are two schemes to solve to cause frequency spectrum resource when operator possesses nonstandard bandwidth

The bandwidth of air-interface of 12MHz, in order to make full use of frequency spectrum resource, can only be divided into 10MHz and 1.4MHz
The combination of standard bandwidth, still has the partial frequency spectrum wasting of resources and not the combination of all of bandwidth can
Carrier aggregation is carried out, while may also need to increase hardware device, causes cost to increase.
Scheme two：In order to reduce and avoiding the interference of adjacent frequency, the two ends of each standard bandwidth in LTE protocol
It is each to have reserved certain bandwidth as protection bandwidth, do not carry out the transmission of useful data.In order to make full use of
The nonstandard bandwidth for being possessed, can strictly be filtered standard bandwidth so that the reserved guarantor of standard bandwidth
Protecting band width protects bandwidth less than standard.As there is the nonstandard bandwidth of 19.2MHz in certain operator, due to 20MHz
The a width of 1MHz of standard protection band of bandwidth, middle 18MHz are used for transmitting useful data, are strictly filtered
Afterwards so that the protection bandwidth at 18MHz bandwidth two ends is less than 1MHz, a width of 0.6MHz of filtered protection band,
The nonstandard bandwidth of 19.2MHz can thus be used.The program is only applicable to nonstandard bandwidth and slightly smaller than marks
The scene of quasi- bandwidth, it is impossible to meet the demand of multiformity nonstandard bandwidth.
Above two solves the scheme that frequency spectrum resource is wasted, and has its certain limitation to meet various
The demand of the nonstandard bandwidth of property.

Embodiment three
The embodiment of the present invention elaborates the distribution condition of resource in the first system bandwidth.
For the terminal for not supporting nonstandard bandwidth, its Resources allocation is directly given in base station in second system bandwidth
Block, terminal is sent to by PDCCH the information that up-downgoing is dispatched, and terminal is issued according to PDCCH
DCI is demodulating Physical Downlink Shared Channel/Physical Uplink Shared Channel (PDSCH/PUSCH, Physical
Downlink Shared Channel/Physical Uplink Shared Channel), realize the transmission of data.
It is right in order to improve the utilization rate of Resource Block in the first system bandwidth of base station while not increasing the power consumption of terminal
It is as follows the step of the terminal for supporting nonstandard bandwidth, resource allocation：
The first step：Preferentially judge whether the resource of spread bandwidth disclosure satisfy that terminal requirements, in order to weigh extension
Bandwidth resources service condition, for the threshold parameter that spread bandwidth arranges two resource utilizations：
E_Threshold1 and E_Threshold2.E1 (T) represents that the actual PRB of current time spread bandwidth is sharp
With rate, E2 (T) represents the PRB utilization rates for being estimated as spread bandwidth after UE distribution PRB.
If E1 (T)<E_Threshold 1 and E2 (T)<E_Threshold 2
The resource utilization for then thinking now spread bandwidth is not too high, can meet the need of the terminal resource
Ask, then to terminal distribution resource in spread bandwidth, otherwise it is assumed that the resource utilization of spread bandwidth is higher,
Then not in spread bandwidth be terminal distribution resource, go to second step.
Second step：In order to weigh second system bandwidth resources service condition, two resource utilizations are equally set
Threshold parameter N_Threshold1 and N_Threshold2.N1 (T) represents current time second system bandwidth
Actual PRB utilization rates, N2 (T) represent be estimated as UE distribution PRB after second system bandwidth RRB
Utilization rate.
If N1 (T)<N_Threshold 1 and N2 (T)<N_Threshold 2
The resource utilization for then thinking now second system bandwidth is not too high, can be met for terminal distribution
The demand of resource, then be terminal distribution resource in second system bandwidth, otherwise goes to the 3rd step.
3rd step：Due to the resource utilization of spread bandwidth and second system bandwidth it is all higher, so need
Be simultaneously terminal distribution Resource Block in two bandwidth, in order to allow terminal can and meanwhile detect in spread bandwidth and
The resource allocation of second system bandwidth, needs base station to issue a MAC CE and notifies terminal simultaneously to expansion bands
Wide and second system bandwidth scheduling.Base station issues two in 1 TTI using the resource of second system bandwidth
PDCCH, PDCCH are the distribution to second system bandwidth resources, and a PDCCH is to extension
The distribution of bandwidth resources, terminal the two PDCCH of meeting blind Detecting in 1 TTI.
4th step：Due to terminal, simultaneously two PDCCH of blind Detecting can cause the power consumption of terminal to increase, and be
The power consumption of terminal is reduced, in the case where spread bandwidth or second system bandwidth can meet terminal requirements, is needed
Base station is wanted only to dispatch the resource of spread bandwidth or second system bandwidth.In order to weigh terminal in spread bandwidth and
The resource service condition of second system bandwidth, arrange two parameters E_UE_Threshold and
N_UE_Threshold.N_UE (T) is expressed as the UE
The meansigma methodss of the ratio of the total RB of regiment commander's alleviating distention in middle-JIAO；E_UE (T) is expressed as the RB that the UE distributes in spread bandwidth
The meansigma methodss of the ratio of total RB in spread bandwidth.
If N_UE (T)<N_UE_Threshold or E_UE (T)<E_UE_Threshold
Then base station needs continuation to judge resource service condition in spread bandwidth, if met：
E1(T)<E_Threshold 1 and E2 (T)<E_Threshold 2, then base station issue MAC CE notify terminal only exist
It is scheduled in spread bandwidth, terminal is also only demodulated PDSCH/PUSCH in spread bandwidth.
Otherwise base station continues to judge second system bandwidth resource allocation, if met：
N1(T)<N_Threshold 1 and N2 (T)<N_Threshold 2
Then base station issues MAC CE and notifies that terminal is only scheduled in second system bandwidth to it, terminal
Only it is demodulated PDSCH/PUSCH in second system bandwidth.
If condition above is unsatisfactory for, base station is continued in spread bandwidth and second system bandwidth to terminal
It is scheduled.
