Description
Technical field
The present invention relates to the mobile communication technology field, the resource allocation techniques between particularly a kind of equidirectional subframes.
Background technology
LTE (Long Term Evolution, Long Term Evolution) system is that physical layer adopts OFDM (Orthogonal Frequency Division Multiplex, OFDM) multicarrier system of technology, the experimental process carrier wave constitutes a Resource Block, and scheduling is a unit with the Resource Block.Present LTE physical-layer techniques research is primarily aimed at FDD (Frequency Division Duplex, Frequency Division Duplexing (FDD)) and two kinds of duplex modes of TDD (TimeDivision Duplex, time division duplex).
For LTE FDD system, the frequency band that the up-downgoing data occupancy is different, the up-downgoing data can be transmitted simultaneously.And for LTE TDD system, the frequency band that the up-downgoing data occupancy is identical, the up-downgoing data can only can not be transmitted simultaneously in corresponding subframe transmission.But no matter be, as long as present scheduling scheme is data to be arranged and have available resources promptly can send data to LTE FDD system or LTE TDD system.
Consult the Type 2 frame structure schematic diagrames that Figure 1 shows that LTE TDD system.Wherein, each long radio frames for 10ms by 2 long be half-frame (field) formation of 5ms, each half-frame longly constitutes for the subframe of 1ms by 5.Type 2 frame structures are supported two kinds of switch-point (conversion) cycles: 5ms, 10ms.No matter to which kind of, subframe #0, subframe # 5 and DwPTS (Downlink Pilot Time Slot, descending pilot frequency time slot) necessarily are used for downlink transfer in switch-point cycle.For the 5msswitch-point cycle, all having the length sum in two half-frame is DwPTS, protection time slot and the UpPTS of 1ms; UpPTS (Uplink Pilot Time slot, uplink pilot time slot) and subframe # 2, subframe # 7 necessarily are used for uplink.For the 10ms switch-point cycle, in two half-frame, all have DwPTS, and protection time slot and UpPTS only are present among first half-frame, and DwPTS length is 1ms among second half-frame; UpPTS and subframe # 2 necessarily are used for uplink, and subframe # 7, subframe #8, subframe #9 necessarily are used for downlink transfer.
For LTE TDD system, the up-downgoing data can not be transmitted simultaneously, may have a plurality of continuous equidirectional subframes like this, particularly to the frame structure of 10ms switch-point.Such as if there are a plurality of continuous sub-frame of uplink, data of before follow-up descending sub frame just need be transmitted in this subframe, accumulating in the continuous sub-frame of uplink so, must cause this descending sub frame load very heavy like this, its resource utilization is very high, again because whole system is synchronous, the subframe load of adjacent sub-district correspondence generally also can be heavier, the corresponding subframe with adjacent sub-district of this descending sub frame uses the probability with the frequency resource to increase so, thereby increase the weight of the co-channel interference of this descending sub frame, make Packet Error Ratio increase poor system performance.
Not only LTE TDD system makes the subframe load heavier when the transmission data easily, easily adjacent sub-district is produced bigger co-channel interference, and all may there be similar problem in the TDD formula communication system similar with LTE TDD system data transmission means.Wherein, TDD formula communication system is meant up-downgoing data occupancy same frequency band, and the up-downgoing data can only as long as data are arranged and have available resources promptly can send data, thereby the communication system of data accumulation phenomenon occur easily in corresponding subframe transmission.
As seen,, when utilizing prior art in subframe, to transmit data, make the subframe load heavier easily, easily adjacent sub-district is produced big co-channel interference for TDD formula communication system.

Embodiment
For solving problems of the prior art, the embodiment of the invention proposes a kind of resource allocation methods of equidirectional subframes.Define a basic conception---subframe type, comprise two kinds of subframe type in the present embodiment: limited subframe of non-resource (being also referred to as soft subframe) and resource-constrained subframe (being also referred to as hard subframe).Wherein, soft subframe is meant the unrestricted subframe of resource utilization; Hard subframe is meant the restricted subframe of resource utilization, and the resource utilization of hard subframe can not surpass certain resource utilization threshold value, and the resource utilization threshold value is generally less than 1.Any one the soft subframe that it is pointed out that any one soft subframe sub-district adjacent with it of each sub-district will stagger mutually.During the identical one group of equidirectional subframes Resources allocation of this programme data transfer direction in to the sub-district, to each current subframe, the type of at first determining this current subframe is soft subframe or hard subframe, if hard subframe, then dynamically determine a resource utilization threshold value for this current subframe, by the load between each subframe being carried out equilibrium in the time domain angle, reaches reducing the purpose of co-channel interference between the adjacent sub-district.
At first, be that example is simply introduced realization principle of the present invention with resource allocation to descending sub frame.
With the omni cell is that example explanation subframe type is set rule, and this rule also is applicable to three sector cells.Carry out cell group in network, make that any two sub-districts are adjacent in twos in each group, general three neighbor cells are one group, and each sub-district order label in the group, and the cell group schematic diagram sees also shown in Figure 2; Be sub-district defined parameters f, value generally equals the sub-district number that comprises in each group, for example f=3; All descending sub frames in each sub-district are unified numbering, represent with Ns.Suppose that three neighbor cells are respectively sub-district 1, sub-district 2 and sub-district 3, the corresponding subframe type set point in each sub-district needs to guarantee that the subframe type set point of each sub-district correspondence in the same group is different and less than the value of parameter f.For example, to sub-district 1, the descending sub frame of setting all Ns mod f==0 is soft subframe, and other descending sub frame is hard subframe; To sub-district 2, the descending sub frame of setting all Ns mod f==1 is soft subframe, and other descending sub frame is hard subframe; To sub-district 3, the descending sub frame that defines all Ns mod f==2 is soft subframe, and other descending sub frame is hard subframe.Wherein, mod represents complementation, can obtain the remainder that two numbers are divided by.Adopt this method, can guarantee that the soft subframe in the neighbor cell staggers mutually.
On the basis of dividing subframe type, be defined as follows parameter:
P
y: the resource utilization threshold value of each hard subframe, initial value are provided with a smaller numerical value, for example with P
yInitial value be set to: P
Y0=14%;
P
r: the resource utilization upper limit of each soft subframe, be also referred to as the maximum resource utilance, generally get P
r=1, promptly the resource utilization of soft subframe is not carried out any restriction;
P
n: the real resource utilance of the subframe of numbering Ns=n.
When hard subframe is carried out resource allocation, work as P
nReach P
yIn time, finish to distribute; When soft subframe is carried out resource allocation, work as P
nReach P
rIn time, finish to distribute, at P
rBe equivalent to in=1 o'clock any restriction is not carried out in the resource allocation of soft subframe, same as the prior art.
If current descending sub frame is hard subframe, the resource utilization threshold value P of this current descending sub frame then
yAdopt the following dynamic scheme of determining.The definition statistical window, width is W, is meant the mean value that calculates the individual real resource utilance at preceding descending sub frame of the W adjacent with current descending sub frame, for variation that can the fast adaptation system loading, the W value is smaller, such as can value being 3.
Whenever the resource allocation that finishes previous descending sub frame, when beginning that current descending sub frame carried out resource allocation, at first calculate the adjacent W of current descending sub frame the average real resource utilance P ' a at preceding descending sub frame, the computing formula of P ' a is shown in formula [1]:
