Description

Method, device, R-T unit and the communication system of distributing ascending resource
Technical field
The present invention relates to mobile communication technology, relate in particular to the technology of distributing ascending resource under the mobile communications network environment.
Background technology
Along with the progress of science and technology, people are improving constantly the requirement of mobile communication business quality, so the demand that proposition seamlessly transits to the 3G (Third Generation) Moblie technology.Major technique to 3G evolution has GPRS (General Packet Radio Service, GPRS), EDGE (Enhanced Datarates for GSM Evolution, Enhanced Data rates for GSM Evolution), HSCSD (High SpeechCircuit Switched Data, and the emphasis of research concentrates on and utilizes limited frequency spectrum resources to improve transmission rate and reduce propagation delay time the high speed voice circuit switched data).
GPRS is the packet data exchanged technology of introducing in the GSM network, this technology is superimposed on the gsm system, can prolong the useful life of GSM, this technology is based on the forwarding of packet data package and the statistic multiplexing of channel, thereby the transmission rate of the data service that existing GSM provides has been leaped more than the 100Kbps from 9.6Kbps.Because GPRS adopts GMSK (GaussianMinimum Shift Keying, the Guassian Minimum Shift Keying GMSK) modulation system identical with GSM, so the transmission rate of the data service of GPRS still can't reach the 2Mbps speed of 3G business need.
In order fully to satisfy the bandwidth demand that following radio multimedium is used, EDGE provides a transitional scheme from GPRS to the 3G (Third Generation) Moblie, EDGE and UMTS (Universal MobileTelecommunications System, universal mobile telecommunications system) shared core net, by introducing the Iu interface, evolution GSM EDGE Radio Access Network GERAN (GSM EDGE Radio AcesssNetwork, GSM EDGE wireless access network).EDGE is a kind of data enhancement mode mobile communication technology based on the GSM/GPRS network, usually be called the 2.75G technology by people again, the characteristics of this technology mainly are to use broadband service, can allow and use the network of 800MHz, 900MHz, 1800MHz, 1900MHz frequency range that the partial function of 3G (Third Generation) Moblie network is provided, its major technique is as follows:
(1) 8PSK (8Phase Shift Keying, 8 phase shift keyings) modulation: realize 3 bit data of carrying on each modulation signal, and GMSK can only carry the data of 1 bit under kindred circumstances, so the data service maximum transmission rate of EDGE can reach 3 times of GPRS;
(2) 9 kinds of modulation and coded system: i.e. MCS (Modulation and Coding Scheme, modulation coding mode) 1~9, wherein, MCS1~4 have kept the GMSK modulating mode, and the 8PSK modulation is adopted in MCS5~9, and different MCS have been defined different data block sizes and channel redundancy coding;
(3) link adaptation mechanism: promptly these nine kinds of coded systems of MCS1~9 are divided into 3 groups, are respectively Family A (MCS-3, MCS-6, MCS-8, MCS-9), Family B (MCS-2, MCS-5, MCS-7) and Family C (MCS-1, MCS-4), in communication process, coded system can change on the same group, selects coded system according to carrier/interface ratio during data re-transmission, when guaranteeing speech quality, the use of maximum Radio Resource;
(4) steadily increase redundancy transmission means (Incremental redundancy): in the GPRS transfer of data, if error code appears in data block, then this data block will retransmit, correct until transmission, and in the EDGE technology, introduced the incremental redundancy mode, this mode combines ARQ (Automatic RepeatReQuest, repeat requests) and FEC (Forward Error Correction automatically, the forward error verification) two kinds of technology, data block adopts different hole knockouts when retransmitting, and the result that will at every turn transmit at receiving terminal effectively recombinates, and recovers legacy data, thereby reduced the number of times that retransmits, improved the efficient of transmission.
In the wireless resource allocation mode, two kinds of different mechanism are used in uplink and downlink.TBF (Temporary Block Flow, Temporary Block Flow) is the interim connection between MS (travelling carriage) and the network, only just exists in the process of data forwarding.TBF is supported in the unidirectional forwarding of LLC (Logical Link Contral, the logic link control) Packet Data Unit on the grouping physical channel.A TBF can go up at one or more PDCH (Packet Data Channel, Packet Data Channel) and use Radio Resource.Network allocation is called PDCH for the time slot of GPRS, and a plurality of time slots can be combined as the PDCH group.Network has distributed TFI (Temporary Flow Identity, Temporary Block Flow indication) for each TBF, and in the TBF of Chu Xianing, the TFI of each TBF is different at the same time.The PDCH that network uses for the MS assignment by control information, on the descending PDCH that distributes, MS is by detecting the ownership that TFI discerns this TBF; On the up PDCH that distributes, MS is by monitoring USF (the Uplink StateFlag on the corresponding descending PDCH, the uplink state sign), the up PDCH that determine to use promptly, has different USF values during the corresponding different MS of each PDCH, network determines by control USF which MS up PDCH returns use, in addition, also can make the multiplexing same PDCH of a plurality of MS, realize the dynamic assignment of ascending resource.Network can be the coded system that MS specifies up use by control messages also.
At present, the method to the ascending resource dynamic assignment comprises DA (Dynamic Allocation, dynamic assignment) and EDA methods such as (Extended Dynamic Allocation, extended dynamic allocation).
When adopting the DA method of salary distribution, each MS need monitor USF on the descending PDCH of the up PDCH correspondence of each distribution, and when monitoring corresponding USF value, MS is the next radio block transmission upstream data on same PDCH just.When MS only distributes a up PDCH, the DA method of salary distribution as shown in Figure 1, suppose that MS is to find on the PDCH1 that the value of USF is x1 at descending time slot 1, then MS thinks that network distributed to its ascending resource, and MS will send upstream data at the radio block of the ascending time slot 1 of next block period.
When adopting the EDA method of salary distribution, each MS sequence number from allocated channel is minimum begins to monitor, monitor successively from low to high then, as long as receiving corresponding USF value back at certain channel just monitors no longer backward, on all subsequent channel of same channel and distribution, send upstream data afterwards, need on each corresponding down channel, all not receive USF.
A GPRS MS can be with a kind of pattern work of three class operational modes such as category-A, category-B or C class.Under the category-A pattern, MS can carry out GSM audio call Circuit Service and GPRS data packet services simultaneously.The DTM of MS (Dual Transfer Mode, double-transmission mode) is meant that MS has at least one TBF Radio Resource simultaneously under circuit connection state, and BSS (Base Station Subsystem, base station sub-system) can coordinate and make its Radio Resource to work in coordination.Can support the MS of double-transmission mode DTM to be necessary for category-A MS, and network and MS support the DTM ability simultaneously.
At present, transfer of data is Block (radio block) at the minimum scheduling unit of physical layer, and each Block is made up of 4 time slots, and lays respectively at 4 continuous TDMA (Time Division MultipleAccess, time division multiple access) frame is so the propagation delay time of each Block all is 20ms.As shown in Figure 2,52 time slots of 52-multiframe (52 multi-frame) have 12 Block according to the arrangement of Fig. 2, and the cycle of each 52 multi-frame is 240ms, and the evaluation duration of each Block equals 20ms like this.High level data is to be encapsulated among the Block to transmit, and at present, each TTI (Transmission Timing Interval, Transmission Time Interval) duration is 20ms, and promptly each high level data has the time delay of 20ms at least.For reducing this section time delay, those of ordinary skills have proposed RTTI (Reduced TTI reduces Transmission Time Interval) technology again.The overall thought of RTTI is keep each Block big or small constant, reduces TTI by utilizing multicarrier or multi-slot.RTTI comprises two kinds of technology, that is: increase the multicarrier bandwidth and increase the multi-slot bandwidth in time domain at frequency domain.
Time domain RTTI technology as shown in Figure 3, B1 is on 4 continuous T DMA frames, every frame is with 1 time slot, then the TTI of B1 equals 20ms, this is the technology of using before the RTTI; B2 is on 2 continuous tdma frames, and every frame is with 2 continuous time slot, and then the TTI of B2 equals 10ms, is called 10ms RTTI radio block; In like manner, the TTI of B3 equals 5ms, is called 5ms RTTI radio block, and B2, B3 represent to adopt the technology behind the RTTI.RTTI technology under the multicarrier is meant and illustrates being received within on 2 frames of 2 carrier waves in original 4 time slots or on 1 frame of 4 carrier waves, distinguishing the TTI of corresponding 10ms and 5ms like this, no longer providing here.
Be that compatibility considers, up can multiplexing 10ms RTTI MS and 20ms TTI tradition MS, the position of USF can not change, and reads USF to guarantee that two kinds of MS can both monitor.Descending USF still is 20ms, but RTTI radio block that can dispatching uplink 10ms.As shown in Figure 4, up 10ms RTTI radio block is multiplexing at up PDCH1 and PDCH2, and MS monitors USF at descending PDCH1 of correspondence and PDCH2.If arrive the USF of oneself at the last channel monitoring of paired channel, just the preceding 10ms at up paired channel sends upstream data; If arrive the USF of oneself at a back channel monitoring of paired channel, just the back 10ms at up paired channel sends upstream data.For example, MS monitors the USF-A of oneself on PDCH1, and just the preceding 10ms at up PDCH1 and PDCH2 sends data, and another MS monitors the USF-D of oneself on PDCH2, and just the back 10ms at up PDCH1 and PDCH2 sends data.
Under 10ms RTTI technology, MS and network are all supported DTM, use 3 time slots to be example respectively with up-downgoing, and grouped data is all used 10ms RTTI technology, provide the ascending resource under the following method scheduling DTM pattern.
As shown in Figure 5, up CS (Circuit Switched, circuit switching) time slot is at up PS (PacketSwitched, packet switching) time slot both sides, CS is at time slot 1, owing to send the time that needs 1 time slot between the reception at least, so in order to satisfy the MS multislot capability, promptly measure and the transmitting-receiving ability, grouping downlink be the TBF of 10ms RTTI in time slot 0 and 2, the TBF of packet uplink 10ms RTTI is in time slot 2 and 3.Because of the CS time slot has caused the scheduling of USF on time slot not corresponding, i.e. the RTTI radio block of USF dispatching uplink time slot 2 on the time slot 0 and 3 preceding 10ms, the RTTI radio block of USF dispatching uplink time slot 2 on the time slot 2 and 3 back 10ms.
As shown in Figure 6, up CS time slot is in the middle of up PS, and CS is at time slot 2, measure and the transmitting-receiving transfer capability for satisfying MS, grouping downlink be 10ms RTTI in time slot 0 and 1, up 10ms RTTI is in time slot 1 and 3.Because of the CS time slot has caused the scheduling of USF on time slot not corresponding, i.e. the RTTI radio block of USF dispatching uplink time slot 1 on the time slot 0 and 3 preceding 10ms, the RTTI radio block of USF dispatching uplink time slot 1 on the time slot 1 and 3 back 10ms.
Under 10ms RTTI technology, MS can't monitor whole down channels of up paired channel correspondence sometimes owing to reasons such as measurement, multislot capability restriction or uplink and downlink configurations.
For example, MS and network are all supported DTM, and the business demand of network based MS, Figure 6 shows that this MS has distributed 3 time slots respectively in up-downgoing at network using such as Fig. 5, and one of them uplink and downlink timeslot is the CS time slot, and grouped data is all used 10ms RTTI technology.
As shown in Figure 5, up CS time slot at up PS time slot on one side, CS is at time slot 1, owing to send the time that needs 1 time slot between receiving at least, so in order to satisfy the MS multislot capability, promptly measure and the transmitting-receiving ability, grouping downlink be the TBF of 10ms RTTI in time slot 0 and 2, the TBF of packet uplink 10msRTTI is in time slot 2 and 3.This moment, MS can't monitor the descending time slot 3 of up paired time slot 2 and 3 correspondences, and can only monitor descending time slot 2, and like this, network just can't be to the Radio Resource of whole 20ms of this MS flexible dispatching ascending time slot 2 and 3.According to the USF scheduling mode of Fig. 4, MS can only use the Radio Resource of the preceding 10ms of up paired time slot 2 and 3, and can't use the Radio Resource of back 10ms, so can cause the wasting of resources.
MS is at packet transfer mode PTM (Packet Transfer Mode, packet transfer mode) under, also can occur to monitor the situation of whole down channels of up paired channel correspondence sometimes owing to reasons such as measurement, multislot capability restriction or uplink and downlink configurations.For example, this MS under the PTM pattern and MS under the DTM pattern shown in Figure 6 all adopt RTTI technology and up TBF multiplexing at identical Radio Resource, i.e. ascending time slot 1 and 3.This MS under the PTM can't corresponding monitor descending time slot 3, and can only monitor descending time slot 1, and like this, network just can't be to the Radio Resource of whole 20ms of this MS flexible dispatching ascending time slot 1 and 3.According to the USF scheduling mode of Fig. 4, MS can only use the Radio Resource of the preceding 10ms of up paired time slot 1 and 3, and can't use the Radio Resource of back 10ms, so can cause the wasting of resources.
Therefore.Adopt the MS of 10ms RTTI technology, no matter under DTM still is the PTM pattern, the situation of whole down channels of up paired channel correspondence all may occur to monitor, produce network and can't be scheduled to the problem that the ascending resource of the whole 20ms of channel is caused the wasting of resources flexibly for MS.

Embodiment
Below we will be in conjunction with the accompanying drawings, optimum implementation of the present invention is described in detail.At first it is to be noted, the implication of the term of using among the present invention, words and claim can not only only limit to its literal and common implication and go to understand, the implication and the notion that also comprise and then conform to technology of the present invention, this is because we are as the inventor, to suitably provide the definition of term, so that the most appropriate description is carried out in our invention.Therefore, the configuration that provides in this explanation and the accompanying drawing is first-selected embodiment of the present invention, rather than will enumerates all technical characteristics of the present invention.We will recognize to also have the various equivalent scheme or the modifications that can replace our scheme.
The invention provides a kind of method of distributing ascending resource, the overall technical architecture of described method comprises the following steps: as shown in Figure 7
S701: network distributes at least one uplink state sign USF at the down channel of up paired channel correspondence, is used to indicate the part or all of ascending resource of described up paired channel;
S702: network is notified to described MS with the information of the USF that distributes and corresponding ascending resource thereof.
Wherein, in pairs channel is meant two time slots that radio block distributed that adopt 10ms RTTI technology, and these two time slots can be continuous, also can be at interval.
Down channel be for can be moved the down channel that platform MS monitors, for example the descending time slot among Fig. 50 and 2 and Fig. 6 in descending time slot 0 and 1.
Down channel can be the previous channel in the descending paired channel or a back channel or all paired channel.
The part ascending resource can refer to the RTTI radio block of preceding 10ms of up paired channel or the RTTI radio block of back 10ms, and all ascending resources can refer to the RTTI radio block of two 10ms of whole 20ms of up paired channel.
When up employing RTTI technology, measure under the condition with multislot capability satisfying MS, the scheduling of up 10ms RTTI radio block is still kept the relation of time slot correspondence.Because of limited by the MS multislot capability, one of them channel when the paired channel of up RTTI, a channel for example, when not having corresponding down channel to indicate, be that MS can't monitor this channel in the paired channel, network can be provided with USF on the down channel of for example last channel correspondence by another channel in paired channel, is used to refer to the RTTI ascending resource how MS uses paired channel.When ascending resource assignation, at least one the USF value of a channel allocation in the paired channel that can monitor for MS, the flexible instruct MS of different USF values is used different ascending resources.
Now the USF to different numbers may corresponding ascending resource distribution condition describe, and wherein, USF is at a MS:
(1) if be 1 USF of this channel allocation, then this USF indicates the RTTI radio block of the preceding 10ms of paired channel, perhaps indicates the RTTI radio block of the back 10ms of paired channel, perhaps indicates the RTTI radio block of 2 10ms of whole 20ms of paired channel;
(2) if be 2 USF of this channel allocation, then 1 USF indicates the RTTI radio block of preceding 10ms of paired channel or the RTTI radio block of back 10ms, and another USF is expressed as the RTTI radio block to 2 10ms of whole 20ms of channel;
(3) if be 3 USF of this channel allocation, the RTTI radio block of indicating the preceding 10ms of paired channel of 1 USF wherein then, 1 USF wherein indicates the RTTI radio block of the back 10ms of paired channel, and another USF is expressed as the RTTI radio block to 2 10ms of whole 20ms of channel.
For the DTM pattern, MS can't monitor whole down channels of up paired channel correspondence, up RTTI resource dynamic distribution condition of the present invention such as Fig. 8 and shown in Figure 9 owing to reasons such as measurement, multislot capability restriction or descending distribution.
As shown in Figure 8, network is that 1 MS distributes 2 USF, i.e. USF-m and USF-n on time slot 2.With Fig. 5 is example, uplink scheduling still adopts the mode of time slot correspondence, USF on the time slot 0 still can dispatch corresponding ascending time slot 0, for representing this MS, USF-m can use the RTTI radio block of the preceding 10ms of ascending time slot 2 and 3 on the time slot 2, for representing this MS, USF-n can use the RTTI radio block of whole 20ms of ascending time slot 2 and 3 on the time slot 2, i.e. the RTTI radio block of 2 10ms.When the USF-n on the time slot 2 indication will take the whole 20ms resource of time slot 3, the USF on the network time slot 3 was set to retention USF-Rsv, and the corresponding ascending resource of expression keeps to this MS and uses.
As shown in Figure 9, network is that 1 MS distributes 3 USF, i.e. USF-x, USF-y and USF-z on time slot 2.With Fig. 5 is example, uplink scheduling still adopts the mode of time slot correspondence, USF on the time slot 0 still can dispatch corresponding ascending time slot 0, for representing this MS, USF-x can use the RTTI radio block of ascending time slot 2 and 3 preceding 10ms on the time slot 2, for representing this MS, USF-y can use the RTTI radio block of ascending time slot 2 and 3 whole 20ms on the time slot 2, promptly the RTTI radio block of 2 10ms can use the RTTI radio block of ascending time slot 2 and 3 back 10ms for USF-z represents this MS on the time slot 2.When the USF-y on the time slot 2 indication will take the whole 20ms resource of time slot 3, the USF on the network time slot 3 was set to retention USF-Rsv, and the corresponding ascending resource of expression keeps to this MS and uses.
For the PTM pattern, MS can't monitor whole down channels of up paired channel correspondence, up RTTI resource dynamic distribution condition of the present invention such as Figure 10, Figure 11 and shown in Figure 12 owing to reasons such as measurement, multislot capability restriction or descending distribution.
As shown in Figure 10, network is that 1 MS distributes 2 USF on time slot 2, i.e. USF-m and USF-n, this MS under the PTM pattern and MS under the DTM pattern shown in Figure 5 all adopt RTTI technology and uplink and downlink TBF multiplexing at identical Radio Resource.For the PTM pattern, the uplink scheduling of this MS also can adopt the mode of time slot correspondence, USF on the time slot 0 still can dispatch corresponding ascending time slot 0, for representing this MS, USF-m can use the RTTI radio block of the preceding 10ms of ascending time slot 2 and 3 on the time slot 2, for representing this MS, USF-n can use the RTTI radio block of whole 20ms of ascending time slot 2 and 3 on the time slot 2, i.e. the RTTI radio block of 2 10ms.When the USF-n on the time slot 2 indication will take the whole 20ms resource of time slot 3, the USF on the network time slot 3 was set to retention USF-Rsv, and the corresponding ascending resource of expression keeps to this MS and uses.
As shown in Figure 11, network is that 1 MS distributes 3 USF on time slot 2, i.e. USF-x, USF-y and USF-z, this MS under the PTM pattern and MS under the DTM pattern shown in Figure 5 all adopt RTTI technology and uplink and downlink TBF multiplexing at identical Radio Resource.For the PTM pattern, the uplink scheduling of this MS also can adopt the mode of time slot correspondence, USF on the time slot 0 still can dispatch corresponding ascending time slot 0, for representing this MS, USF-x can use the RTTI radio block of ascending time slot 2 and 3 preceding 10ms on the time slot 2, for representing this MS, USF-y can use the RTTI radio block of ascending time slot 2 and 3 whole 20ms on the time slot 2, promptly the RTTI radio block of 2 10ms can use the RTTI radio block of ascending time slot 2 and 3 back 10ms for USF-z represents this MS on the time slot 2.When the USF-y on the time slot 2 indication will take the whole 20ms resource of time slot 3, the USF on the network time slot 3 was set to retention USF-Rsv, and the corresponding ascending resource of expression keeps to this MS and uses.
As shown in Figure 12, network is that 1 MS distributes 3 USF on time slot 1, i.e. USF-i, USF-j and USF-k, this MS under the PTM pattern and MS under the DTM pattern shown in Figure 6 all adopt RTTI technology and up TBF multiplexing at identical Radio Resource.For the PTM pattern, the uplink scheduling of this MS also adopts the mode of time slot correspondence, for representing this MS, USF-i can use the RTTI radio block of ascending time slot 2 and 3 preceding 10ms on the time slot 1, for representing this MS, USF-j can use the RTTI radio block of ascending time slot 2 and 3 whole 20ms on the time slot 1, promptly the RTTI radio block of 2 10ms can use the RTTI radio block of ascending time slot 2 and 3 back 10ms for USF-k represents this MS on the time slot 1.When the USF-j on the time slot 1 indication will take the whole 20ms resource of time slot 3, the USF on the network time slot 3 was set to retention USF-Rsv, and the corresponding ascending resource of expression keeps to this MS and uses.
Referring again to Fig. 5 and Fig. 6, in the RTTI uplink scheduling method under the DTM that Fig. 5 and Fig. 6 provide, if the USF of descending time slot 0 has dispatched ascending time slot 2,3 (as shown in Figure 4) or 1,3 (as shown in Figure 5), just can not be used for dispatching uplink time slot 0, will produce the ascending resource waste this moment.
In Fig. 8-12, descending time slot 0 has two USF values, be respectively USF-A and USF-B, suppose that USF-A and USF-B distribute to user A and the corresponding USF value of user B (being MS), when network scheduling USF-A, user A can send upstream data at the 20msRTTI radio block of up 0 time slot of next block period, and when network scheduling USF-B, user B can send upstream data at the 20msRTTI radio block of up 0 time slot of next block period.So in Fig. 8-12, the USF on the descending time slot 0 still can dispatch corresponding ascending time slot 0, this is with regard to the problem of the wasting of resources that solved ascending time slot 0.
In Figure 12, descending time slot 1 is respectively USF-i, USF-j and USF-k for MS has distributed 3 USF.Network can these 3 USF values of flexible dispatching, make the MS of this employing 10ms RTTI technology can use the Radio Resource of whole 20ms of up paired time slot 1 and 3 flexibly, solve the problem of waste of radio resources on the up paired time slot.
Network judges that MS will adopt up RTTI technology under DTM, just the down channel in the last channel correspondence of the paired channel of up RTTI is that MS distributes USF, make the corresponding different RTTI ascending resource of different USF values, corresponding indication specifically has following dual mode by up TBF assignment related news notice MS:
(1) network is distinguished corresponding different resources in order with the USF value that MS arranges different numbers on this channel, and network is at least 1 USF value of this channel allocation in up TBF assignment message, and needn't indicate corresponding certain ascending resource of concrete certain USF value.For example network and MS can reach following agreement: be 1 USF of this channel allocation, this USF indicates the preceding 10ms of paired channel, or back 10ms, or whole 20ms resource; Distribute 2 USF, the preceding 10ms resource of the paired channel of indication that the USF value is less, the resource of the whole 20ms of the paired channel of the indication that the USF value is bigger; Distribute 3 USF, 10ms resource before the minimum paired channel of indication of USF value, 10ms resource behind the less paired channel of indication of USF value, the resource of the whole 20ms of the paired channel of indication of USF value maximum;
(2) complete network is by the different ascending resources of the different USF correspondence of up TBF assignment message notice MS.Be at least 1 USF value of this channel allocation in the assignment message, and indicate the corresponding ascending resource of each USF value.For example, in the assignment message 1 USF of this channel allocation, also need to indicate corresponding which type of ascending resource of this USF.
Owing to need make amendment, so now the TBF assignment message is described to original TBF assignment message.
The form of original packet uplink assignment message segment is as follows in the TBF assignment message:
{ 0--Timeslot Allocation // ascending time slot distributes: power contorl parameters is not with in 0 expression
{ 0|1<USF_TN0:bit (3)〉} // 0 is not for distributing TS0; 1 is distribution T S0;
There is corresponding USF value the back during // distribution T S0, otherwise does not have
{0|1<USF_TN1:bit(3)>}
{0|1<USF_TN2:bit(3)>}
{0|1<USF_TN3:bit(3)>}
{0|1<USF_TN4:bit(3)>}
{0|1<USF_TN5:bit(3)>}
{0|1<USF_TN6:bit(3)>}
{0|1<USF_TN7:bit(3)>}
The present invention has carried out following modification to the TBF assignment message:
Keep original packet uplink assignment message segment in the TBF assignment message, wherein, the USF value of distributed time slot correspondence is scheduled to the preceding 10ms to time slot.Utilize the idle bit space in the message, the uplink assignment message segment that design replenishes, concrete form is as follows:
{ the ascending time slot distribution that 0|1--Supplementary Timeslot Allocation//benefit does not have;
// 0 is not have this message segment in the message, and 1 for there being this message segment, and promptly this message segment is optional
<Resource Type:bit (1)〉// 0 the indication paired time slot back 10ms; Whole 20ms of the paired time slot of 1 indication;
{ 0|1<USF_TN0:bit (3)〉} // 0 is not for indicating TS0; 1 is indication TS0, and has only
// former " packet uplink assignment message segment " distributed time slot could be indicated;
There is corresponding USF value the back during // indication TS0, the resource that corresponding ResourceType is provided with
// when not indicating TS0 otherwise do not have corresponding USF value.
{0|1<USF_TN1:bit(3)>}
{0|1<USF_TN2:bit(3)>}
{0|1<USF_TN3:bit(3)>}
{0|1<USF_TN4:bit(3)>}
{0|1<USF_TN5:bit(3)>}
{0|1<USF_TN6:bit(3)>}
{0|1<USF_TN7:bit(3)>}
}
}
