Description
Technical field
The present invention relates to the radio transmission technical field of IEEE 802.16 systems, relate to a kind of method or rather according to the reliability requirement transmitting business stream.
Background technology
IEEE 802.1 6 protocol definitions the wireless metropolitan area network standard of fixed broadband wireless access (BWA), this standard pin has defined different physical-layer techniques to different frequency range.The range of application of this standard mainly is towards dwelling house, small office/family office (SOHO), teleworker and the user of small enterprise (SME) market.
The frame structure of uplink frame comprises sub-frame of uplink as shown in Figure 1 in IEEE 802.16 agreement time division duplex (TDD) systems, and sub-frame of uplink is made up of a plurality of UL Burst PDU usually.
The frame structure of downlink frame then as shown in Figure 2.This frame structure specifically comprises descending sub frame, comprise in the descending sub frame that being used for terminal realizes the synchronous leading symbol (Preamble) of downlink frame, is used to indicate the code modulation mode of back broadcast part and frame control head (FCH), broadcast and the DL Burst PDU of message-length, and DL Burst PDU is generally more than one.Wherein, comprise downlink map message (DL_MAP) and uplink map message (UL_MAP) in the broadcast, the DL_MAP message definition base station be handed down to the code modulation mode of each burst in the descending sub frame of terminal and distribute to the Radio Resource of each terminal, UL_MAP message has then defined the code modulation mode of each burst in the sub-frame of uplink that terminal sends to the base station and the Radio Resource that each terminal can take.
This shows that employed up and downlink space interface resource is finished in the reciprocal process of up-downgoing business by the base station centralized dispatching, promptly by DL_MAP message and indicating downlink and the up resource allocation respectively of UL_MAP message in terminal and base station.The method of carrying out the interface-free resources distribution by these two kinds of message is identical, is example with UL_MAP distribution of messages ascending idle port resource only below therefore.
UL_MAP_IE in the UL_MAP message is as shown in table 1.UL_MAP message generally includes a plurality of UL_MAP_IE.

Table 1
For the up-link wireless frame, its interface-free resources is divided into a plurality of burst, and each terminal can only use one of them burst, promptly has only the information among the burst relevant with same terminal in every frame.For each burst, all need indicate the shared interface-free resources of this burst, the employed code modulation mode of this burst (UIUC) and the pairing terminal of this burst by a UL_MAP_IE in the UL_MAP message.Therefore, terminal can be determined the burst corresponding with this terminal according to the UL_MAP_IE in the UL_MAP message, and determines position and the employed UIUC of this burst of this burst, can send the corresponding business data by this burst afterwards.
Based on above-mentioned resource allocation mechanism, terminal is when having a plurality of Business Stream, and is as follows by up process to base station transmission information:
The qos requirement of each Business Stream that steps A, base station have according to terminal is determined the scheduling strategy at each Business Stream of this terminal;
Step B, base station calculate the required physical resource of this terminal according to the scheduling strategy of each Business Stream in this terminal, and operable code modulation mode, and indicate to terminal by UL_MAP message;
Step C, terminal be according to the indicated physical resource of UL_MAP message, and according to the qos requirement of each Business Stream in this terminal, these Business Streams are dispatched, promptly in a certain order or alternate manner the data message of these Business Streams is packaged into MAC PDU;
Step D, terminal are cascaded to the MAC PDU of each Business Stream together again, and carry out unified coding and modulation;
Step e, the terminal data message after with coded modulation sends for the interface-free resources that self distributes by the base station.
Under above-mentioned resource assignation mode, the number of the UL_MAP_IE that is comprised in UL_MAP message and the DL_MAP message is identical with the burst number in the ascending-descending subframes, and each terminal has only a burst corresponding with it in frame, therefore the IE number in the message only need equate with the number of terminals of carrying out Business Processing, thereby as can be seen, the IE number in UL_MAP message and the DL_MAP message is less in the present this scheme.Less I E number makes that the shared empty overhead of UL_MAP message and DL_MAP message is also fewer.
But this mode need be carried out unified coding and modulation with the data message of each Business Stream in the same terminal, thereby make the different business stream in the same terminal have identical reliability, and same subterminal different business flow to toward having different reliability requirements.Such as, a terminal has two different business and connects, it is respectively the professional and VoIP business of HTTP, the BER of these two kinds of business requires to be respectively 10^-6 and 10^-3, and because base station assigned up-downgoing resource all is based on terminal, these two the professional data messages that connect that are terminal are launched with same code modulation mode in same radio frames, therefore guarantee for these two the professional reliabilities that provide same that connect.And, if the base station is when the code modulation mode that is provided with at this terminal, be to be connected to benchmark with HTTP, then guarantee identical with the professional connection of HTTP for the professional reliability that connects of VoIP, in fact the VoIP business is not high to the requirement of reliability, connects the interface-free resources that identical reliability has been wasted system for it is provided with HTTP.And if the base station is provided with reliability according to the VoIP business, then obviously can't reach the professional reliability requirement that connects of HTTP.
In sum, present interface-free resources allocative decision obviously can't satisfy the different requirements of Business Streams different under the same terminal to reliability.

Embodiment
The present invention program at first needs to revise up-downgoing resource assignation mode.Because different business may have different reliabilities, therefore, the present invention program is when distributing the up-downgoing resource, can be for different traffic assignments different burst, afterwards between base station and terminal during data message transmission, the burst by correspondence transmits with the data message of different business.
Wherein, being the different burst of different traffic assignments, can be that the type of service of directly supporting according to terminal is distributed burst, such as, if terminal is supported two types business, then can distribute corresponding burst respectively for these two kinds of types of service.The scheme that can also distribute burst according to the service dispatching type.The service dispatching type is classified according to qos requirement, and reliability is a kind of in the qos parameter, the reliability requirement of the miscellaneous service under the same service dispatching type is roughly the same, therefore distributes burst can satisfy the requirement of different business to reliability according to the service dispatching type.
To be categorized as example, to reach specific embodiment in conjunction with the accompanying drawings the present invention program is described in further detail below according to the service dispatching type.
Because the transmission of the data message of Business Stream is divided into the uplink and downlink both direction, therefore respectively the processing of this both direction is described.For the scheme that adopts UL_MAP distribution of messages burst, when distributing burst, at first in the UL_MAP_IE of UL_MAP message, increase the service dispatching type indication territory (Service Schedule Type) that is used for the identification service scheduling type for up direction.The UL_MAP_IE that increases behind this indication territory is as shown in table 2.

Table 2
Wherein, because present service dispatching type has 5 kinds, be respectively UGS, rtPS, ertPS, nrtPS and BE, also promptly Business Stream can be divided into 5 classes based on the service dispatching type, therefore this indication territory can be made as 3bit, and 0b000 sign UGS, 0b001 sign rtPS, 0b010 sign ertPS, 0b011 sign nrtPS, the 0b100 sign BE in the indication territory can be set.Afterwards, can be in UL_MAP_IE identify service dispatching type under the Business Stream that transmits among the corresponding burst by Service Schedule Type.
By above-mentioned setting; if in the terminal a plurality of Business Streams are arranged; and these Business Streams belong to different service dispatching types; and the UL_MAP_IE that is provided with in the UL_MAP message need be corresponding with the service dispatching type; therefore; usually have the Business Stream that more than one UL_MAP_IE identifies same terminal in the UL_MAP message, obviously this will make UL_MAP message take more interface-free resources.
And, the identical situation of reliability requirement of two or more different business scheduling type may appear also in fact, the Business Stream that just can use a burst transmission to belong to the different business scheduling type and have uniform reliability in this case.This just needs a UL_MAP_IE can identify the multiple business scheduling type, therefore can be set to 5bit by Service Schedule Type, and adopts the mode of the indication of lighting a lamp to identify different service dispatching types.Such as, the Service Schedule Type of 5bit is 0bx1x2x3x4x5, wherein,
X1 identifies UGS, and indicates during x1=1 and occurred the UGS business among the corresponding burst, indicates during x1=0 not occur the UGS business among the corresponding burst;
X2 identifies rtPS, and indicates during x2=1 and occurred the rtPS business among the corresponding burst, indicates during x2=0 not occur the rtPS business among the corresponding burst;
X3 identifies ertPS, and indicates during x3=1 and occurred the ertPS business among the corresponding burst, indicates during x3=0 not occur the ertPS business among the corresponding burst;
X4 identifies nrtPS, and indicates that occurred among the corresponding burst could the nrtPS business during x4=1, indicates during x4=0 not occur the nrtPS business among the corresponding burst;
X5 identifies BE, and indicates that occurred among the corresponding burst could the BE business during x5=1, indicates during x5=0 not occur the BE business among the corresponding burst.
Like this, for UL_MAP_IE,, illustrate then that the Business Stream that transmits among the indicated burst of this UL_MAP_IE comprises and belong to the professional and BE business of rtps if Service Schedule Type wherein is 0b0001000001.Obviously, can reduce the shared interface-free resources of UL_MAP message by a UL_MAP_IE indication multiple business scheduling type as far as possible.
Based on above-mentioned setting, the realization flow of the present invention program's up direction as shown in Figure 3, corresponding following steps:
The qos requirement of each Business Stream that step 301, base station have according to terminal is determined the scheduling strategy at each Business Stream of this terminal.
Also be that the service dispatching type that each Business Stream is affiliated is determined in the base station.
In this step, calculate in required code modulation mode of the burst of every class service dispatching type correspondence and the prior art basic identically according to the scheduling strategy of each Business Stream in the terminal, therefore repeat no more for the terminal distribution code modulation mode.
In this step, if the reliability requirement of different business scheduling type is identical, then common burst can be distributed for these several service dispatching types in the base station.
In this step, terminal needs earlier the data message in the same service dispatching type to be packaged into MACPDU.The MAC PDU that will belong to each Business Stream of same service dispatching type again carries out partition packetization and cascade.The data message that obtains after the cascade belongs to different service dispatching types respectively.Certainly,, and distributed identical burst, then the data message of these several service dispatching types can have been carried out partition packetization and cascade together for these several service dispatching types if there is two or more service dispatching type to have identical reliability.Afterwards, the Various types of data message that terminal obtains cascade again carries out chnnel coding respectively, interweaves, planisphere mapping and OFDM modulation, and the data message after will modulate again shines upon also modulate emission on the burst that the service dispatching type that the base station belongs to for such data message is distributed goes out.
By above-mentioned steps, can be implemented on the up direction, the burst that the data message of each Business Stream in the terminal is distributed for the service dispatching type by the base station sends to the base station.The base station is after the information that receives on this burst, can determine code modulation mode and the pairing terminal thereof of this burst according to the method for salary distribution before self, obtain the information among this burst afterwards, and with the respective coding modulation system to its processing such as decode, thereby obtain corresponding data message.
For the scheme that adopts DL_MAP distribution of messages burst, when distributing burst for down direction, because burst is being distributed according to the service dispatching type in the base station, and after by burst the data message of corresponding service scheduling type being handed down to terminal, terminal only need determine whether the information among this burst sends to self according to Basic CID, and do not need to know the pairing service dispatching type of this burst, therefore, do not need the DL_MAP_IE in the DL_MAP message is carried out any modification, only need the base station to distribute burst according to the service dispatching type, the Basic CID and the code modulation mode of the pairing terminal of this burst are sent to terminal, and send corresponding data message by this burst.
Based on above-mentioned setting, the realization flow of the present invention program's down direction as shown in Figure 4, corresponding following steps:
The qos requirement of each Business Stream that step 401, base station have according to terminal is determined the scheduling strategy at each Business Stream of this terminal.
Step 402, base station are the corresponding burst of traffic flow assignment in every class service dispatching type, and calculate the required code modulation mode of burst of every class service dispatching type correspondence according to the scheduling strategy of each Business Stream in this terminal.
Equally, if the reliability requirement of different business scheduling type is identical, then common burst can be distributed for these several service dispatching types in the base station.
The service dispatching type that each Business Stream belongs to is determined according to the qos requirement of each Business Stream in the terminal in step 403, base station, this data message that belongs in each Business Stream of same service dispatching type is sent to this terminal by corresponding burst, also will send to this terminal simultaneously by the Basic CID that the DL_MAP_IE in the DL_MAP message will distribute to the burst of each terminal shared interface-free resources, the employed code modulation mode of this burst and corresponding terminal.
Wherein, the base station sends datagram according to burst and specifically comprises: the data message that will belong in each Business Stream of same service dispatching type is packaged into MAC PDU, and the MAC PDU that belongs to same service dispatching type carried out partition packetization and cascade, afterwards the Various types of data message that obtains carried out chnnel coding respectively, interweave, planisphere mapping and modulation, launch on the burst that the service dispatching type that the data message after the coded modulation is belonged to for such data message in this base station is distributed again.
By above-mentioned steps, can be implemented on the down direction, the base station sends to terminal with the burst that the data message of each Business Stream of terminal distributes for the service dispatching type by this base station.Afterwards, terminal can determine that whether information among this burst is for sending to this terminal information according to the Basic CID that DL_MAP_IE provided in the DL_MAP message, and in definite this information for after sending to this terminal information, determine the code modulation mode of this burst according to DL_MAP_IE, and utilize the processing such as decode of this code modulation mode, thereby obtain corresponding data message.
Above-mentioned handling process based on Fig. 3 and Fig. 4 has realized distributing burst based on the service dispatching type.As previously mentioned, the professional connection type that the present invention program can also directly support according to terminal distributes burst, and this processing scheme is in fact similar with Fig. 3 and Fig. 4.Different is, when distributing the burst of up direction, because each professional connection is only at specific terminal, if connection distributes burst according to business, then the sign that can directly connect by business is defined as the pairing terminal of burst that this business connection distributes.Therefore,, need in UL_MAP_IE, not increase the indication territory that is used for the identification service connection, the professional identification information that connects only need be set in the CID of UL_MAP_IE get final product for scheme by UL_MAP distribution of messages burst.For the burst that connects the allocation of downlink direction based on business, then with based on the service dispatching type distribute burst identical, only needing the base station is professional the connection to distribute corresponding burst, send the data message that this business connects by this burst, and the employed channel coding method of this burst and the Basic CID that should business connects pairing terminal are sent to terminal get final product.
In addition,, can connect for different business equally and distribute a burst, with the quantity of the burst that is reduced to a terminal distribution with uniform reliability for the scheme of connect distributing burst according to business.And for distributing sub-frame of uplink, can also reduce the quantity of the UL_MAP_IE in the UL_MAP message, thereby reduce the shared interface-free resources of UL_MAP message.
The above only is the present invention program's preferred embodiment, not in order to limit protection scope of the present invention.
