Description
Technical field
The present invention relates to the communications field, relate in particular to the assignment techniques of Radio Resource.
Background technology
OFDM (Orthogonal Frequency Division Multiplex, OFDM) is a kind of physical-layer techniques that adopts among the AIEPhase2 (access of MBWA mobile broadband wireless), this technology is divided into the narrow-band sub-carriers of some quadratures with the physical layer resources in the wireless communication system in frequency domain, high-speed data-flow is parallel transmission on the narrow-band sub-carriers of described some quadratures by string and conversion.
Because the narrow-band characteristic of carrier wave can overcome multi-path influence, therefore using described OFDM technology can eliminate intersymbol interference greatly; And because the orthogonal property of subcarrier, promptly the frequency spectrum between subcarrier is overlapped, can improve the utilance of frequency spectrum when therefore utilizing described OFDM technical communication.This is because the above-mentioned advantage of OFDM technology makes the OFDM technology just become the development trend of mobile communication system.Two big mobile communication standards organize 3GPP and 3GPP2 when proposing the developing direction of follow-on mobile communication in the world at present, all with the OFDM technology as essential technology, so that can effectively eliminate the ISI (intersymbol interference) of high speed business, reduce the complexity of broadband high-speed rate mobile communication system.
Physical layer resources in the ofdm system can be regarded the two dimensional surface that is formed by " time domain " and " frequency domain " as, the available frequencies resource is divided into N fundamental frequency transmission unit, and fundamental frequency transmission unit is a subcarrier or the frequency subband that consists of a plurality of sub-carriers; Simultaneously, the physical layer resources in the transmission time periods (OFDM frame) by M basic time transmission unit constitute, each basic transmission time unit comprises one or more OFDM symbol.
In the mobile communication system that adopts frequency division OFDM, usually at one time in, a plurality of users take same OFDM physical frame (this is the feature of frequency division OFDM) jointly, and this just need be that AT distributes different Radio Resources according to the size of user's traffic carrying capacity.
At present, adopt the mode of channel trees to realize AT wireless resource allocation and management usually.When being the AT distributing radio resource, once be a logic Radio Resource of user's assignment position, the corresponding ChanID (channel logo) in described logic Radio Resource position, a node on the described ChanID channel tree.When the Radio Resource of AT being managed based on described channel trees, after if certain channel id is assigned to certain AT, then all channel ids below it are also taken by described AT, in case that is to say certain channel id distributes to AT and uses, all channel ids below it just can not participate in scheduling once more, and the channel id above it can not participate in scheduling.
For example for the FDD system of the OFDMA of 5M bandwidth, 6bit ChanID can 64 kinds of different base node of assignment (BaseNodes), and the resource granularity of indication is respectively 1,2,4,8,16,32 BaseNodes, the BaseNodes in the concrete ChanID correspondence channel trees as shown in Figure 1.As seen from Figure 1, this channel trees comprises 32 BaseNode (the 5M bandwidth can be divided into 512 subcarriers, and each BaseNode comprises 16 subcarriers), and described BaseNode is the node of corresponding nethermost numbering from 31 to 62 respectively.
When Radio Resource is managed, if the ChanID of node 31 correspondences is assigned to user A, then be node 15,7, the ChanID of 3,1,0 correspondence can not participate in scheduling.If the ChanID of node 3 correspondences is assigned to user A, then channel is positioned at the node 7,8,15,16 below it, 17,18,31,32,33,34,35,36,37 and the ChanID of 38 correspondences, and be positioned at node 0 above it and the ChanID of 1 correspondence can not participate in scheduling once more.
The prior art relevant with the present invention provides a kind of Radio Resource assignment scheme, and its implementation process comprises as shown in Figure 2:
Step S101, after traffic control began, AN (Access Network) checked whether there are available resources, can resource, then execution in step S102 if exist; Otherwise, execution in step S107.
Step S102, the QoS according to dispatching algorithm, different AT or different business correspondence determines the AT that is scheduled for.
Step S103, AN check that the AT be scheduled for is current and whether had available resource, if do not exist, and execution in step S104 then; Otherwise, execution in step S105.
Step S104 carries out initial resource allocation according to the situation of AN surplus resources and the QoS of AT business to AT, changes step S106 then over to.
Step S105 adjusts the existing Radio Resource of AT, changes step S106 then over to.
Step S106 carries out channelizing to the assignment message that is provided with, then emission.
Step S107 finishes traffic control.
The process of carrying out resource allocation among above-mentioned steps S104 and the step S105 is undertaken by FLAM (forward direction resource assignation) or RLAM (oppositely resource assignation) assignment message, and the message structure of described FLAM and RLAM assignment message is as shown in table 1:
| Field | Block type | MACID | Persis -tent | ChanID | PF | Dura tion | Ext. TX | Timing | Suppl | Rank |
| # |
3 | 9-11 | 1 | 6-8 | 4-6 | 2 | 1 | 6 | 1 | 2 |
| Access Grant | 000 | 1 | 0 | 0 | 0 | 0 | 0 | 1 | 0 | 0 |
| FLAM | 010 | 0 | 1 | 1 | 1 | 0 | 1 | 0 | 1 | 0 |
| RLAM | 011 | 0 | 1 | 1 | 1 | 0 | 1 | 0 | 1 | 0 |
| MCW FLAM1 | 100 | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined |
| MCW FLAM2 | 101 | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined |
| SCW FLAM | 110 | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined | Undetermined |
Table 1
As can be seen from Table 1, comprise MACID, ChanID and Suppl (abbreviation of Supplment) territory in the message structure.The MACID of " MACID " territory respective user wherein; The channel id that " ChanID " territory correspondence is assigned, the length N FL_CHANID in this territory is relevant with the size of channel trees; The Supplment territory is for replenishing the position.
When in step S104 AT being carried out initial resource allocation, described Supplment territory is set to " 0 " or is not provided with.
When in step S104, when assigned radio resource has been adjusted, utilizing Persistent resource adjustment mode to carry out to AT.At this moment, described Supplment territory can be set to " 0 " or not be provided with; Also can be set to " 1 ".
When the supplement position is set to 0 (not being provided with), then the expression with Supplment position in the current assignment message with the pairing Radio Resource of ChanID replace the current Radio Resource of described AT.
When described Supplment position is set to " 1 ", if described FLAM or RLAM assignment message with the Radio Resource of the ChanID correspondence pairing Radio Resource of ChanID that do not belong to current resource and covered, then be expressed as described AT current wireless resource increase described Supplment position with the Radio Resource of ChanID correspondence; If this assignment message with the pairing Radio Resource of ChanID belong to the pairing Radio Resource of ChanID that current resource covers, then represent the Radio Resource that described AT is current deduct described Supplment position with the Radio Resource of ChanID correspondence.
By prior art as can be seen, when AN is that AT is when carrying out first Resources allocation, the Supplment territory of carrying in described FLAM or the RLAM assignment message is set to " 0 " or is not provided with, therefore AN by assignment message can only assignment the Radio Resource of specified particle size, for example for the system of 5M bandwidth, AN by an assignment message can assignment the Radio Resource granularity can only be 1,2,4,8, a kind of in the logic Radio Resource position of 16,32 Basenodes correspondences, so the assignment limited ability of AN; In addition, when AN needs assignment to be different from the Radio Resource of above-mentioned granularity, then need repeatedly to use assignment message, can waste interface-free resources so undoubtedly.

Embodiment
Consider when AN adjusts AT existing wireless resource, utilized the thought of Supplement domain information position, the present invention is when carrying out the initial wireless resource allocation to AT, utilized described Supplement domain information position equally, and described Supplement domain information position is arranged on the highest order of ChanID, the ChanID territory is arranged on all the other information bits of ChanID, and makes the length of described ChanID equal the length of described Supplement domain information position and the length sum of described ChanID domain information position.AT just can calculate corresponding ChanID with described ChanID domain information position according to described Supplement domain information position like this, determine the logic Radio Resource position of oneself then according to described ChanID, and get access to corresponding radio resource according to described logic Radio Resource position.
First embodiment provided by the invention is a kind of assigning method of Radio Resource, its core is: when AN carries out resource allocation to the AT that does not have Radio Resource, the Supplement information bit of carrying in the assignment message is set to the highest order of ChanID, is described AT assignment Radio Resource by described assignment message then.In implementing process of the present invention, described AN and AT side are all used the channel trees with spline structure, and represent corresponding logical resource position with the node of described channel trees.The specific implementation process of first embodiment provided by the invention comprises as shown in Figure 3:
Step S200, when Access Network AN is that the current access terminal AT that does not have a Radio Resource is when carrying out resource allocation, in sending to the assignation information of AT, carry Supplment territory and ChID territory for described AT assigned radio resource information as required, and utilize a ChID of the common expression of information bit in described Supplment domain information position and channel logo ChID territory to come assigned resources.
Step S300, after described assignation information arrives described AT, described AT calculates corresponding ChID according to Supplment territory in the described assignation information and ChID territory, and determine oneself logical resource position, and get access to institute's assigned radio resource according to described logical resource position according to described ChID.
The implementation process of step S200 among first embodiment is as shown in Figure 4, and is specific as follows:
Step S201, after traffic control began, AN checked whether there are available resources, if there are available resources, execution in step S202 then; Otherwise, execution in step S207.
If the QoS of current AT is higher, then the resource that reduces the lower AT of some QoS according to dispatching algorithm makes the higher AT of described current QoS obtain the situation of Resources allocation, thinks that there are available resources in described AN.
Step S202, the QoS according to dispatching algorithm, different AT or different business correspondence determines the AT that is scheduled for.
Step S203, AN check the current available resources that whether existed of AT be scheduled for, if do not exist, and execution in step S204 then; Otherwise, execution in step S205.
At the first access network of AT or during the No-Persistent of resource allocation (non-persistent taking), because AN centralized control resource assignation situation, AN knows the Radio Resource situation that AT is current, Radio Resource situation and the current service of relevant AT, therefore, when AN carried out resource allocation, AN knew the current Resources allocation of which AT, and which AT is current not to have Resources allocation.
Step S204, QoS according to the situation and the AT business of AN surplus resources, determine to be AT institute assigned radio resource, pass through RLAM or FLAM assignment message then to the described Radio Resource of AT assignment, the highest order of the ChanID of the logic Radio Resource correspondence that the information bit in the Supplment territory in the wherein said assignment message is set to be assigned with, the information bit in ChID territory is arranged on all the other positions of described ChanID, and the information bit length sum that makes the information bit length in Supplment territory and ChID territory equals the length of ChanID, changes step S206 then over to.
Be not have the user of Resources allocation to carry out allocation of radio resources at current among the step S204, the structure of assignment message is still as shown in table 1.After the highest order of the ChanID of the logic Radio Resource correspondence that the information bit in Supplment territory is set to be assigned with, the logic Radio Resource granularity of described ChanID correspondence can double.System with the 5M bandwidth is that example describes:
If the Supplement information bit in the assignment message is set to " 0 " or when not being provided with, this moment the ChanID correspondence be the BaseNodes of the logic Radio Resource correspondence of 6bit, this moment, allocative decision was consistent with associated description of the prior art.Be set to the highest order of ChanID when the supplement information bit after, that the ChanID correspondence is the BaseNodes of the logic Radio Resource correspondence of 7bit at this moment, and the Radio Resource granularity of institute's assignment can double in the assignment message like this.The channel trees of correspondence is as shown in Figure 5 at this moment:
After the Supplment information bit was set to the highest order of ChanID, its corresponding ChanID became 7bit, and AN just can be by 128 kinds of different BaseNodes of ChanID assignment of described 7bit like this, and the Radio Resource granularity that can indicate is respectively 1,2,3,4,5,6,7,8,9 ... 32.
In addition, after doubling on the basis of original C hanID, when carrying out resource allocation, whole Radio Resource need be divided into groups, after the grouping, support Different Logic Radio Resource granularity by the BaseNodes in every group.The present invention is in order to consider the compatibility with existing scheme, distribute the method for preceding 64 kinds of wireless resource blocks to carry out according to the method for distributing radio resource piece in the prior art, for ChanID is the wireless resource block of 63～127 correspondences, can distribute in the following manner:
First kind of mode: every continuous 3 BaseNodes are divided into one group, every group of corresponding ChanID; And the like, until using up all ChanID.Except the remainder part, need 10 ChanID altogether.
The second way: every continuous 5 BaseNodes are divided into one group, every group of corresponding ChanID, and the like, until using up all ChanID.Except the remainder part, need 6 ChanID altogether.
The third mode: every continuous 6 BaseNodes are divided into one group, every group of corresponding ChanID, and the like, until using up all ChanID.Except the remainder part, need 5 ChanID altogether.
When grouping, can select from left to right, also can select from right to left.For the system greater than 5M, the allocation strategy of resource can carry out similar methods and distribute.
Certainly discontinuous BaseNodes can also be divided into one group, every group of corresponding ChanID, and the like, until using up all ChanID.
Step S205 adjusts the existing Radio Resource of AT, changes step S106 then over to.
To the AT of Resources allocation, allocation algorithm same as the prior art is adopted in the distribution of resource.
Step S206 carries out channelizing to the assignment message that is provided with, then emission.
Step S207 finishes traffic control.
Receive the RLAM or FLAM assignment message of described AN transmission as AT after, need read the value of supplement bit, and the value of it and ChID combined determine own logical resource position, and get access to institute's assigned radio resource according to the logical resource position after definite.Be the implementation process of the step S300 among first embodiment below, as shown in Figure 6, comprise the steps:
Step S301, AT receives resource allocating message.
Step S302, AT judge whether oneself has had Radio Resource, if have, and execution in step S303 then; Otherwise, execution in step S304.
Step S303, AT adjusts mode according to described Persistent resource of the prior art the Radio Resource that has had is adjusted.
The specific implementation process of step S303 and associated description of the prior art are identical, are not described in detail here.
Step S304, AT read the value of the Supplment domain information position in the described assignment message and the value of ChID domain information position.
Step S305, the value of the value of Supplment domain information position and ChID domain information position combined calculates ChID, obtains institute's assigned radio resource according to described ChID then.
Still the system with the 5M bandwidth is an example, supposes that the value that AT learns Supplment domain information position is " 1 ", the value of the information bit in ChID territory be " 1 ", then the ChID that calculates this moment is the ChID of corresponding 7bit; Suppose that the value that AT learns Supplment domain information position is " 0 ", the value of the information bit in ChID territory be " 1 ", then the ChID that calculates at this moment is the ChID of corresponding 6bit.
Step S306 after finishing institute's assigned radio resource and reading, finishes.
