Description
Technical field
The present invention relates to communication technical field, particularly a kind of data transmission method and device.
Background technology
Along with development of Communication Technique, GSM (Global System for Mobile communications, global system for mobile communications) system has experienced multiple evolution and development in the 3-G (Generation Three mobile communication system) transition process.Wherein Packet Service comprises GPRS (General Packet Radio Service, GPRS) technology, EGPRS (Enhanced GPRS, the GPRS of enhancing) technology, EGPRS2 is technological and Precoded EGPRS2 technology.GPRS has introduced the notion of radio block, and the burst (burst) that timeslot number is identical on promptly continuous four tdma frames forms a radio block.Beginning all message transmission from the GPRS technology all is to accomplish through setting up TBF (Temporary Block Flow, Temporary Block Flow), and a TBF is used to accomplish the transmission of some user profile.TBF by in the radio block one be called TFI (Temporary Flow Identity; The Temporary Block Flow indication) field identifies; For descending TBF; To one's name whether the TFI that one or more PDCH (Packet Data Channel, Packet Data Channel) that the terminal is distributed through inspection go up in each data block head decide this data block.For up TBF, because a plurality of terminal maybe be multiplexing on same PDCH, for fear of the general ascending resource method of salary distribution that adopts based on USF (Uplink State Flag, uplink state sign) of conflict.Network is when setting up up TBF; Give USF of terminal distribution; Descending radio block on one or more PDCH that terminal monitors is distributed if the USF that carries in its head equals to distribute to the USF of oneself, shows that then this terminal can transmit at the next radio block of corresponding up PDCH.
BTTI (Basic Transmission Time Interval, basic Transmission Time Interval) transmission means refers to radio block and takies the burst (time of about 20ms) on continuous four tdma frames on the time slot, and is as shown in Figure 1.RTTI (Reduced Transmission Time Interval; The reduction Transmission Time Interval) transmission means is through using two time slots to transmit four bursts of a radio block; The BTTI radio block that is about to last four the continuous T DMA frames of original single PDCH changes to the RTTI radio block of two last 2 continuous T DMA frames of PDCH; As shown in Figure 2, wherein transmitted a RTTI radio block in the time of Frame x and two frames of Frame x+1.Because the introducing of RTTI does not support the terminal of RTTI can't solve through RTTI transmission means information transmitted, the introducing of RTTI has simultaneously also influenced the mapping of USF.In order to reduce that traditional influence of not supporting the RTTI terminal has been defined two kinds of USF patterns, be respectively: BTTI USF and RTTI USF.The former is meant, though the transmission means of radio block is RTTI, and the transmission means of USF or BTTI, i.e. two continuous RTTI radio blocks have been striden in the transmission of USF, and are as shown in Figure 3.Therefore under BTTI USF configuration,, also can solve the USF in the RTTI radio block even RTTI is not supported at the terminal.RTTI USF is meant that then USF is the same with radio block, all in 10ms, transmits, and is as shown in Figure 4.Therefore under RTTI USF pattern, the terminal that the USF in the RTTI radio block can only be supported RTTI solves.
Introduced new transmission means owing to Precoded EGPRS2 in the prior art; Support the terminal of Precoded EGPRS2 just can solve the radio block that transmits with Precoded EGPRS2 mode so have only; Even use the method for BTTI USF configuration; Its USF that carries also can only dispatch the terminal of supporting PrecodedEGPRS2, and can't dispatch any terminal that other do not support Precoded EGPRS2.Therefore; Even there is a large amount of downlink business at Precoded EGPRS2 terminal; Network also can only abandon sending Precoded EGPRS2 radio block in order to dispatch traditional terminal of not supporting Precoded EGPRS2; Then send the otherwise radio block (like the EGPRS2 radio block) of transmission, finally make the gain of the physical layer that Precoded EGPRS2 is brought have a greatly reduced quality.

Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
First embodiment of the invention has proposed a kind of data transmission method, and its flow process is as shown in Figure 5, comprising:
501: be first's burst allocation first transmission means of radio block, be second portion burst allocation second transmission means of said radio block;
502: be burst of said first and said second portion burst allocation Packet Data Channel;
503: burst of said first and the burst of said second portion are transmitted with said first transmission means and said second transmission means respectively on the data channel that is distributed.
The embodiment of the invention is through mix using different transmission meanss in a radio block, reached that different time-gap transmits through different transmission meanss in a radio block, makes full use of the advantage of different transmission meanss, improved the multiplexing efficient of grouped channels.
Need to prove that in the present embodiment, executive agent can be the base station.Wherein, first transmission means can be the GPRS second stage Precoded EGPRS2 transmission means of the enhancing of precoding, and said second transmission means can be the GPRS second stage EGPRS2 transmission means that strengthens.First transmission means and second transmission means can also be other transmission meanss, like GPRS, EGPRS.
Second embodiment of the invention is use Precoded EGPRS2 transmission means and the EGPRS2 transmission means method as example illustrative embodiment 1 to mix in the radio block, and its flow process is as shown in Figure 6, comprising:
601: be the burst allocation Precoded EGPRS2 of radio block first mode, and transmit through first Packet Data Channel.
Concrete, in radio block, mix and use different transmission meanss, time slots different in the radio block is transmitted through different transmission meanss, can make full use of the advantage of two kinds of different transmission meanss, improved the multiplexing efficient of grouped channels.In the present embodiment, use EGPRS2 and Precoded EGPRS2 transmission means to give an example to mix.
Further; Because Precoded EGPRS2 has introduced new transmission means; Just support the terminal of Precoded EGPRS2 can solve the radio block that transmits with Precoded EGPRS2 mode so have only, therefore, in order to improve multiplexing of channel efficient; In a radio block, mix to use EGPRS2 and PrecodedEGPRS2 transmission means to transmit, make the transmission means that the base station can be different according to the different flexible allocation at terminal.Because Precoded EGPRS2 transmission means does not change the symbolic number that each modulation coding mode carried and the effective information number of bits of EGPRS2 transmission means; A descending radio block (after confirming modulation coding mode) transmits through Precoded EGPRS2 mode or EGPRS2 mode so, and its amount of information of carrying is consistent.For example, be x through radio block loaded information bit in the EGPRS2 mode through the DAS-5 modulation coding mode, still be x through DAS-5 radio block loaded information bit in the Precoded EGPRS2 mode so.Therefore can part burst in four bursts in the same radio block be transmitted through Precoded EGPRS2 mode, other bursts are transmitted through the EGPRS2 mode.The purpose of so doing is to issue these terminal information (like USF) for the terminal of not supporting Precoded EGPRS2 mode can from the burst that the EGPRS2 mode is transmitted, be solved.Simultaneously,, also can untie the burst of transmitting with the EGPRS2 mode, so can untie the information in the radio block of this use mixed transport mode owing to support the terminal of PrecodedEGPRS2 mode can untie the burst of transmitting with Precoded EGPRS2 mode.
Concrete mode can for:
The RTTI radio block is under the configuration of BTTI USF, and the burst of the first of two continuous RTTI radio blocks in BTTI cycle uses Precoded EGPRS2 mode to transmit successively on first Packet Data Channel.A USF is carried in these four bursts, and the terminal that this USF can only be supported Precoded EGPRS2 solves.
602: be radio block second portion burst allocation EGPRS2 mode, and transmit through second Packet Data Channel.
Concrete, the second portion burst of two continuous RTTI radio blocks in BTTI cycle uses the EGPRS2 mode to transmit successively on second Packet Data Channel.Another USF is carried in these four bursts, and this USF can be supported EGPRS2 but do not support the terminal of Precoded EGPRS2 to solve.Need to prove that 602 can carry out with 601 simultaneously, also can before or after 601, carry out, do not limit carrying out sequencing.
For example; As shown in Figure 7; Use BTTI USF configuration down; USF is mapped in respectively in four the continuous bursts of (the 3rd time slot is called PDCH2 below) of first Packet Data Channel through the bit that produces after chnnel coding and the step such as interweave, and transmits through Precoded EGPRS2 mode.Understand for ease, the part that will be mapped in above-mentioned first burst through the USF (being called USF2) of PDCH2 transmission is called USF2_0, and the part that is mapped to 3 remaining bursts by that analogy is respectively USF2_1, USF2_2, USF2_3.
Another USF is mapped in respectively in four the continuous bursts of (the 4th time slot is called PDCH3 below) of second Packet Data Channel through the bit that produces after chnnel coding and the step such as interweave, and transmits through the EGPRS2 mode.Understand for ease, the part that will be mapped in above-mentioned first burst through the USF (being called USF3) of PDCH3 transmission is called USF3_0, and the part that is mapped to 3 remaining bursts by that analogy is respectively USF3_1, USF3_2, USF3_3.In this case, do not support the terminal of Precoded EGPRS2 mode from the burst of transmitting through the EGPRS2 mode, to solve USF3.
Further; The scheme of present embodiment can be generalized under the general situation; Be that the base station selects part burst to use Precoded EGPRS2 mode to transmit in any one radio block (no matter being RTTI radio block or BTTI radio block) according to the variation of wireless environment, other bursts use the EGPRS2 mode to transmit.
In addition, the RTTI radio block also can use EGPRS2 and Precoded EGPRS2 transmission means to transmit through mixing under the configuration of RTTI USF or under the configuration of BTTI.Though mixed transport can not be brought the benefit that improves upstream packet channel multiplexing efficient under the both of these case, can adapt to the variation of wireless environment in the network better, can promote the demodulation performance of radio block.
603: receiving side terminal receives and solves the information of issuing oneself.
Concrete, descending radio block is divided into two parts, and a part is USF, and another part is the data beyond the USF.A plurality of terminals possibly all receive same descending radio block, but have only two terminals can think that this radio block has comprised and own relevant information at most, and other-end then can be lost this radio block.One is the recipient of data division in these two terminals, and it issues oneself according to the data division that the TFI of radio block head judges this radio block.Another is the recipient of USF, and it judges according to the USF of radio block head whether USF equals the USF that distributes to own, if equal, it knows that next up-link wireless piece distributed to oneself so, it can be on next up-link wireless piece transmission information.Sent this two-part information in step 601 and the step 602 respectively.
Further, one section complete information is transmitted by four bursts, in each burst all the fragment of existing data division the fragment of USF part is also arranged.Be that data division or USF have only and just can solve after having received all four bursts.The recipient judges through TFI or USF to the radio block head after receiving radio block, is that the information that sends to oneself is then further handled, and no, and words then abandon this radio block.
The embodiment of the invention is used EGPRS2 and two kinds of transmission meanss of Precoded EGPRS2 through in a radio block, mixing; Improved the multiplexing efficient of grouped channels; Reached and in a radio block, both made full use of the link layer gain that Precoded EGPRS2 transmission means is brought, can utilize USF scheduling in the burst that the EGPRS2 mode transmits not support the effect at the terminal of Precoded EGPRS2 again.
Referring to Fig. 8, the embodiment of the invention provides a kind of data transmission device, comprising:
Concrete, in radio block, mix and use different transmission meanss, time slots different in the radio block is transmitted through different transmission meanss, can make full use of the advantage of two kinds of different transmission meanss, improved the multiplexing efficient of grouped channels.
Wherein, First distribution module 1 specifically is used to be used to the GPRS second stage Precoded EGPRS2 transmission means of enhancing of first's burst allocation precoding of radio block, the GPRS second stage EGPRS2 transmission means that strengthens for the second portion burst allocation of said radio block.
Concrete, be burst of said first and said second portion burst allocation different packets data channel.After the burst allocation transmission means of the different time-gap of 1 pair of radio block of first distribution module number, distribute the burst allocation Packet Data Channel of transmission means through 2 pairs of second distribution module.
Concrete, said device can be the base station.Through the burst in the radio block behind second distribution module, the 2 assigns packet data channels, the transmission means of distributing with first distribution module 1 through transport module 3 is transferred to the terminal.
The embodiment of the invention is through mix using different transmission meanss in a radio block, reached that different time-gap transmits through different transmission meanss in a radio block, makes full use of the advantage of different transmission meanss, improved the multiplexing efficient of grouped channels.
