Description
The application requires to submit on June 19th, 2007 priority of the Chinese patent application that Patent Office of the People's Republic of China, application number are 200710111964.3, denomination of invention is " realizing method, base station and the user terminal of ascending resource scheduling ", and its full content is by reference in conjunction with in this application.
Technical field
The present invention relates to the allocation of radio resources field, particularly a kind of method, base station and user terminal of realizing ascending resource scheduling.
Background technology
In the method for salary distribution of the Radio Resource of wireless access network, two kinds of different mechanism are used in uplink and downlink.Temporary Block Flow (Temporary Block Flow, TBF) is interim connection between travelling carriage (Mobile Station, MS) and network, only in the process of data retransmission, just exists; It is supported in the unidirectional forwarding of the Packet Data Unit on the grouping physical channel.A TBF can be at the upper Radio Resource that uses of one or more Packet Data Channels (Packet Data Channel, PDCH).Network has distributed Temporary Block Flow indication (Temporary Flow Identity, TFI) for each TBF, and in the TBF occurred at the same time, the TFI of each TBF is different.Network is the PDCH that the MS assignment is used by control information.On the descending PDCH distributed, MS identifies the ownership of this TBF by detecting TFI.On the up PDCH distributed, MS, by monitoring the uplink state sign (Uplink State Flag, USF) on corresponding descending PDCH, determines the up PDCH used.Be that the corresponding different MS of each PDCH has different USF values, network determines by controlling USF which MS up PDCH returns use.
Transfer of data is radio block (Block) at the minimum scheduling unit of physical layer at present, each Block is comprised of 4 time slots, and lay respectively at 4 continuous tdma frames, in Block, the propagation delay time of each time slot is the duration of a tdma frame, approximate 5ms, so the propagation delay time of each Block is 20ms.For reducing by this section time delay, minimizing Transmission Time Interval technology (Reduced Transmission TimeInterval, RTTI) has been proposed.The RTTI overall thought is to keep the size of each Block constant, by utilizing multicarrier or multi-slot, reduces Transmission Time Interval (Transmission Time Interval, TTI).
Time domain RTTI technology, referring to Fig. 1, B1 represents the basic Transmission Time Interval technology (Basic Transmission Time Interval, BTTI) before RTTI, B2 represents RTTI.Wherein B1 is on 4 continuous T DMA frames, 1 time slot for every frame, and the TTI of B1 equals 20ms; B2 on 2 continuous tdma frames, 2 continuous time slots for every frame, the TTI of B2 equals 10ms.
For compatibility is considered, up can multiplexing 10ms RTTI MS and 20ms BTTI MS, the position of USF can not change, and to guarantee that two kinds of MS can monitor, reads USF.Descending USF is still 20ms, but RTTI radio block that can dispatching uplink 10ms.
After introducing RTTI, for up RTTI TBF, two kinds of USF patterns (mode) are arranged: BTTI USF mode and RTTI USF mode.When adopting RTTI USF mode, only has RTTI TBF; When adopting BTTIUSF mode, can RTTI TBF be arranged again existing BTTI TBF.As USF GRANULARITY=1, to 4 granularity scheduling of up employing.
Referring to Fig. 2, under BTTI USF mode:
That MS3 and MS4 adopt is BTTI TBF, and that MS1 and MS2 adopt is RTTI TBF.
For MS1 and MS2, on the MS1 PDCH that sequence number is lower in down channel in pairs during at block period Bx, (DL PDCH0) reads the USF1 of appointment, just can be from comprising continuous 4 block periods that next block period Bx+1 starts (Bx+1, Bx+2, Bx+3, Bx+4) front 10ms send upstream data; On the MS2 PDCH that sequence number is higher in down channel in pairs during at block period Bx, (DL PDCH1) reads the USF2 of appointment, just can be from comprising continuous 4 block periods that next block period Bx+1 starts (Bx+1, Bx+2, Bx+3, Bx+4) rear 10ms send upstream data.And network is by 3 block period (Bx+1 after Bx, Bx+2, Bx+3) on the PDCH that upper sequence number is lower or higher, USF retention (reserved USF) is set, MS1 and MS2 can ignore after the Bx cycle on 3 block periods the USF value on corresponding PDCH.
For MS3 and MS4, read the USF3 of appointment at block period Bx as MS3, just can from comprising continuous 4 block periods that next block period Bx+1 starts, (Bx+1, Bx+2, Bx+3, Bx+4) send upstream data.Read the USF4 of appointment as MS4 at block period Bx, just can from comprising continuous 4 block periods that next block period Bx+1 starts, (Bx+1, Bx+2, Bx+3, Bx+4) send upstream data.
Referring to Fig. 3, under RTTI USF mode:
The cycle of Block is compressed to 10ms, and MS1 reads the USF0 of appointment when block period Bx on PDCH pair, just can from comprising continuous 4 block periods that next block period Bx+1 starts, (Bx+1, Bx+2, Bx+3, Bx+4) send upstream data.
The inventor finds in realizing process of the present invention, some special business for example, as the VOIP business generally, user's voice packet every 20ms basically sends once, RTTI USF mode configuration is lower can send a Block by every 10ms.4 granularities of actual employing are divided timing, in distributing to 4 up of MS, owing to being every 10ms continuous dispensing, the user speech bag sent for every 20ms, only understand use 2 (pieces corresponding to front 10ms of each 20ms) at interval, other two (piece corresponding to rear 10ms of each 20ms) do not have data to send, and produces waste, reduces the utilance of channel.The 2nd and the 4th in up channel in Fig. 3 (ULPDCH0 and PDCH1) is exactly two pieces that do not send data.If the every 40ms of user speech bag sends once, use 4 granularities to distribute the waste produced larger.Equally, under BTTI USFmode configuration, the situation that the every 40ms of user speech bag sends once also can produce the waste of channel resource.

Embodiment
The embodiment of the present invention, by revising the instruction content of ascending resource assignment messages, improves the utilance of channel.Specifically, be that the assignment interval of up is set in the ascending resource assignment messages, make up block gap distribute.
Embodiment mono-, realizes the method for ascending resource scheduling, referring to Fig. 4, comprises the steps:
401, base station issues the ascending resource assignment messages, the ascending resource assignment messages comprises USF information and granular information, wherein, granular information is for meaning granularity and the assignment interval of up, and assignment interval is for meaning each transmission time interval of up in 1 granularity.
Base station can also, according to USF information and the granular information in the ascending resource assignment messages, issue to the descending block gap that the dispatching uplink piece is corresponding.When specific implementation, base station can adopt following two steps to issue with realizing descending block gap:
402, base station, according to USF information and granular information in the ascending resource assignment messages, generates the schedule information of up;
403, base station is according to the schedule information of up, and USF corresponding to dispatching uplink piece is at underground of descending middle interval.Adopt the scheme of the present embodiment, base station is according to assignment interval, and compartment of terrain issues descending, like this, user data can send on up of interval, has improved the probability of each up transmitting user data, thereby improved the utilance of channel resource, avoided the waste of ascending resource.
Technical scheme in the present embodiment is applied on different business, the Transmission Time Interval of radio block can be different, for example, when the technical scheme by the present embodiment is applied in the VoIP business, the relevant parameter that USF information is BTTI or the relevant parameter of RTTI; The relevant parameter of BTTI comprises mode parameter and the TFI radio block of BTTI USF; The relevant parameter of RTTI comprises mode parameter and the TFI radio block of RTTI USF.Up comprises BTTI radio block and/or RTTI radio block, and the Transmission Time Interval of BTTI radio block is 20ms, and the Transmission Time Interval of RTTI radio block is 10ms.
In the time of the step specific implementation that issues to descending block gap in above-mentioned steps 403, can comprise:
Underground at descending middle interval of each granularity of USF corresponding to scheduling user terminal.Granularity in above-mentioned steps 401 is integer, the integral multiple that assignment interval is radio block TTI.Assignment interval, except can presetting in base station, also can obtain assignment interval according to user's request, according to the method for user's acquisition request assignment interval, comprises the steps:
Receive the customer service request;
According to described service request, obtain the transmission time interval of user data;
According to the transmitting time of user data, generate the ascending resource assignment messages, the assignment interval in the ascending resource assignment messages is determined according to the transmission time interval of user data.
After the USF that user terminal is assigned in detecting descending, on a up of granularity of correspondence, interval sends user data.
Wherein, assignment interval in the ascending resource assignment messages is determined according to the transmission time interval of user data, according to the existing resource situation in network, the actual transmission demand that correlates user data, such as, the user is by the ftp upload file, it is continuous that data send, the technical scheme that also can apply the embodiment of the present invention realizes the scheduling of ascending resource, network sends the assignment messages at a definite granularity and interval to user terminal, network can be according to the existing resource situation, certain 80ms distributes two granularities (each granularity comprises 4 up), being equivalent to exactly this 80ms all dispatches to this user's use, as found, existing resource is more nervous, and another 80ms can dispatch 1 granularity (each granularity comprises 4 up), in the assignment interval of this 80ms, is 10ms.Under same particle sizes (as 4 of every granularities), the time interval is less, and the time that each granularity completes is shorter, and new scheduling adjustment is just more timely, dispatches more flexible.
Embodiment bis-, the method that realizes ascending resource scheduling in embodiment mono-is applied in the VoIP business, under RTTI USF mode, user data is that every 20ms sends once, TTI is 10ms, according to the transmission time interval 10ms of user data, generate the ascending resource assignment messages, and be handed down to each travelling carriage, the ascending resource assignment messages comprises uplink state sign and granular information, granular information is for meaning granularity and the assignment interval of up, granularity can be integer, the integral multiple that assignment interval is the radio block Transmission Time Interval, in the present embodiment, radio block is for reducing the Transmission Time Interval radio block, the Transmission Time Interval that reduces the Transmission Time Interval radio block is 10ms.In the present embodiment, granular information adopts the USF_GRANULARITY character of 1bit, and USF_GRANULARITY=1 means under 4 granularities (each granularity is distributed 4), in 160ms, network can be dispatched two granularities, and the assignment interval in each granularity is 30ms.Can realize that so every 20ms distributes one, TTI is 10ms, and assignment interval is 10ms.Each MS reads respectively corresponding ascending resource assignment messages, and on up of USF indication, according to assignment interval, interval sends user data.
Referring to Fig. 5, MS1 monitors USF on paired down channel DL PDCH0 and PDCH1, as the USF0 that reads appointment, at next cycle, on corresponding up channel UL PDCH0 and PDCH1, send data, and send next data on the up channel UL PDCH0 of next 40ms and PDCH1, until distribute 4 data.Once MS monitors the USF of appointment, just can monitor the USF in descending that follow-up interval issues, until last up of this granularity number send distributed, USF in continuing again to monitor descending, certainly, in whole process, MS still needs continue to monitor that other are not the USF in interval issue descending.Like this, up of each of distribution all has data to send, and takes full advantage of channel resource.
Wherein, USF_GRANULARITY is the granular information in the present embodiment, for meaning granularity and the assignment interval of up, granular information can also adopt the USF_GRANULARITY character of 2bit, when USF_GRANULARITY is 10, the granularity that means up is 4 o'clock, and every 20ms distributes one up, TTI is 10ms, and assignment interval is 10ms; When USF_GRANULARITY is 11, the granularity that means up is 4 o'clock, and every 40ms distributes one up, and TTI is 10ms, and assignment interval is 30ms; Perhaps adopt USF_GRANULARITY character and extension bits information, the granularity that the USF_GRANULARITY character representation is up, extension bits information means assignment interval, and for example USF_GRANULARITY is 1 o'clock, and the granularity that means up is 4, get one in extension bits, for meaning assignment interval, when the position of getting is 0, mean that every 20ms distributes one up in extension bits, TTI is 10ms, and assignment interval is 10ms; When the position of getting in extension bits is 1, mean that every 40ms distributes one up, TTI is 10ms, and assignment interval is 30ms; Certainly can also adopt other can mean the mode of granular information, for example increase the figure place of USF_GRANULARITY, it is increased to more than 2 or 2, in order to mean more kinds of assignment interval, perhaps in extension bits, get more than 2 or 2, for meaning more kinds of assignment interval, realize the scheduling mode of ascending resource more flexibly.
The transmitting time of user data comprises the packing transmitting time of speech frame or the transmitting time of signaling.Under talking state, if speech frame is arranged, the user normally speaks in conversation, and user 20ms by 1 speech frame packing transmission once, and every 20ms distributes one up; If user 40ms sends 2 speech frame packings once, every 40ms distributes one up; By that analogy, if user 60ms sends 3 speech frame packings once, every 60ms distributes one up ... if there is no speech frame, be that the user mourns in silence in conversation, the transmitting time that transmitting time of user data is signaling, this signaling is the random or periodic allocation of system, for the signaling that means that conversation continues.
Embodiment tri-, under RTTI USF mode, with the difference of embodiment bis-, are, the assignment interval of up is 10ms, and USF_GRANULARITY is 1bit, and USF_GRANULARITY=1 means under 4 granularities, and in 80ms, every 20ms distributes one.And the method for salary distribution of the ascending resource in embodiment bis-is dynamic assignment, that is: each MS need to monitor USF on the descending PDCH corresponding at the up PDCH of each distribution, when monitoring corresponding USF value, the MS just next radio block on same up PDCH sends upstream data; And the method for salary distribution of the ascending resource in the present embodiment is extended dynamic allocation, that is: every MS sequence number from allocated channel, minimum starting monitors, then monitor successively from low to high, as long as receiving corresponding USF value at certain channel just monitors no longer backward, then on all subsequent channel of same channel and distribution, transmission is up, need on the down channel corresponding at each, not receive USF.
Referring to Fig. 6, MS1 at MS1 on paired down channel DL PDCH0 and PDCH1, and paired down channel DL PDCH2 and the upper USF that monitors of PDCH3, when read the USF0 of appointment on down channel DL PDCH0, at next cycle, on corresponding up channel UL PDCH0, PDCH1, PDCH2 and PDCH3, send data, and send next data on the up channel UL of next 20ms PDCH0, PDCH1, PDCH2 and PDCH3, until distribute 4 data.Once MS monitors the USF of appointment, just can monitor the USF in descending that follow-up interval issues, until send last up of this granularity number, USF in continuing again to monitor descending, certainly, in whole process, MS still needs continue to monitor that other are not the USF in interval issue descending.Like this, up of each of distribution all has data to send, and takes full advantage of channel resource, and all user data is all sent by up, has guaranteed the integrality that data send.
Embodiment tetra-, and under BTTI USF mode, the transmitting time of user's bag is that every 40ms sends once, TTI is 10ms, and the assignment interval of up is 30ms, and USF_GRANULARITY is 1bit, USF_GRANULARITY=1, mean under 4 granularities, and in 160ms, every 40ms distributes one.In the present embodiment, that MS3 and MS4 adopt is BTTI TBF, and that MS1 and MS2 adopt is RTTI TBF.
Referring to Fig. 7, for MS1 and MS2, MS1 and MS2 monitor USF respectively on paired down channel DLPDCH0 and PDCH1, on the MS1 PDCH that sequence number is lower in down channel in pairs during at block period Bx, (DL PDCH0) reads the USF1 of appointment, just can be from corresponding up channel ULPDCH0 and PDCH1 10ms send data, and send next data on the front 10ms of the up channel UL PDCH0 of next 40ms and PDCH1.On the MS2 PDCH that sequence number is lower in down channel in pairs during at block period Bx, (DL PDCH0) reads the USF2 of appointment, just can be from corresponding up channel UL PDCH0 and PDCH1 10ms send data, and send next data on the rear 10ms of the up channel ULPDCH0 of next 40ms and PDCH1.Once MS1 and MS2 monitor the USF of appointment, just can monitor the USF in descending that follow-up interval issues, until send last up of this granularity number, USF in continuing again to monitor descending, certainly, in whole process, MS still needs continue to monitor that other are not the USF in interval issue descending.
In the present embodiment, USF1 and corresponding different user MS1 and the MS2 of USF2 difference, USF1 and USF2 also can be set all corresponding to same user, MS1 for example, be respectively used to mean the different business of MS1 at synchronization, for example, in conversation, mean respectively the packing data of the speech frame of MS1 with USF1, USF2 means the signaling of system assignment to MS1.
For MS3 and MS4, MS3 and MS4 monitor USF respectively on paired down channel DL PDCH0 and PDCH1, on the MS3 PDCH that sequence number is lower in down channel in pairs during at block period Bx, (DL PDCH0) reads the USF3 of appointment, just can send data from corresponding up channel UL PDCH0, and send next data on the up channel UL of next 40ms PDCH0.On the MS2 PDCH that sequence number is lower in down channel in pairs during at block period Bx, (DL PDCH0) reads the USF4 of appointment, just can send data from corresponding up channel UL PDCH1, and send next data on the up channel UL of next 40ms PDCH1.Once MS3 and MS4 monitor the USF of appointment, just can monitor the USF in descending that follow-up interval issues, until send last up of this granularity number, USF in continuing again to monitor descending, certainly, in whole process, MS still needs continue to monitor that other are not the USF in interval issue descending.
Embodiment five, under RTTI USF mode, in the present embodiment, the every 20ms of user data sends once, TTI is 10ms, the transmission time interval of user data is 10ms, and the assignment interval of up is 10ms, and the granularity of up is 3, USF_GRANULARITY is 1bit, USF_GRANULARITY=1, mean under 3 granularities, and in 60ms, every 20ms distributes one.
Referring to Fig. 8, MS1 monitors USF on paired down channel DL PDCH0 and PDCH1, read the USF0 of appointment on paired down channel DL PDCH0 and PDCH1 as MS1, at next cycle, on corresponding up channel UL PDCH0 and PDCH1, send data, and send second data on the up channel UL PDCH0 of next 20ms and PDCH1, next 20ms sends the 3rd data on up channel ULPDCH0 and PDCH1 again.Once MS1 monitors the USF of appointment, just can monitor the USF in descending that follow-up interval issues, until send last up of this granularity number, USF in continuing again to monitor descending, certainly, in whole process, MS still needs continue to monitor that other are not the USF in interval issue descending.
