Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of data transmission method, system and device.
Background technology
In the communication system in future; Insert evolution (HSPA+ like high-speed packet; High Speed PacketAccess Plus), Long Term Evolution (LTE; Long Term Evolution) system such as has introduced the message transmission rate and the transmission quality of multiple-input and multiple-output (MIMO, Multiple Input Multiple Output) technology in order to further raising system.
The MIMO technology adopts stream transmission, and promptly the base station is adopted two data to flow to the terminal simultaneously and sent business datum.After the terminal receives two data flow so, need distinguish the operation of double fluid, promptly distinguish each data flow.
Existing FDD (FDD; Frequency Division Duplexing) system's double-current mode of differentiation commonly used comprises: two data flow points are not defined as main flow and auxilliary stream; The exponent number that is the modulation system of main flow use can not be lower than auxilliary stream; Use 16 quadrature amplitude modulation (QAM, QuadratureAmplitude Modulation) modulation such as auxilliary stream, then the modulation system of main flow can adopt 16QAM or 64QAM; But can not be the strong control of four phase shifts (QPSK; Quadri Phase Shift Keying), that is to say that main flow is channel condition that data flow preferably in corresponding the double fluid, auxilliary stream corresponding that relatively poor data flow of channel condition in the double fluid.
In the prior art, the course of work of MIMO stream transmission comprises the steps: in the FDD system
Step 1: the base station is arranged on main flow in the same descending control signaling with the auxilliary Downlink Control Information that flows and sends to the terminal, then, main flow that carries business datum and auxilliary stream is sent to the terminal simultaneously.
Described Downlink Control Information comprises: the base station for the physical resource (like resources such as time slot, code channels) of these two data flow distribution, transformat (like transmission block size (TBS; Modulation system etc.) and mix automatic request retransmission (HARQ, Hybrid Automatic Repeat request) relevant information etc. Transport Block Size).
Step 2: the terminal receives the descending control signaling that send the base station, therefrom reads the Downlink Control Information of main flow and auxilliary stream; And, receive two data flow that carry business datum that send the base station, and detect the channel quality of these two data flow, with channel quality preferably data flow think main flow, the data flow that channel quality is relatively poor is thought auxilliary stream; Then, utilize the control information of main flow that main flow is decoded, the control information that utilizes auxilliary stream is attend institute's loaded service data to auxilliary stream decoding thereby obtain these two data flow.
Step 3: the terminal to two data stream decode obtain the corresponding business data after; Up feedback control signaling to each data flow of base station feedback; Reply (ACK)/non-replying (NACK) signaling, channel quality indication (CQI, Channel Quality Instruction) signaling etc. like two data flow.
After the base station receives the up feedback control signaling that sends at the terminal; Obtain the up feedback control information of two data flow; Wherein comprise CQI separately, so, it is stream main flow or auxilliary that each up feedback control information can be identified according to the value of CQI in the base station; Be about to channel quality preferably data flow think main flow, the data flow that channel quality is relatively poor is thought auxilliary stream.
But; After the CQI information of two data flow of terminal feedback is received in the base station; Sometimes to its correction; If the base station is revised the CQI information of two data flow of terminal feedback, and make the magnitude relationship of CQI of two data flow that variation has taken place after revising, cause the main flow of these two data flow that the base station thinks and the relation of auxilliary stream that variation has taken place.
For example, the base station thinks that first data flow is a main flow when initial, and second data flow is auxilliary stream; The terminal is through the value of the CQI of each data of detection, and identifying first data flow is main flow, and second data flow is auxilliary stream; And to the CQI of first data flow of the base station feedback CQI greater than second data flow, and the base station revises it after receiving the CQI of these two data flow of terminal feedback, causes the CQI of the CQI of second data flow greater than first data flow; Thereby make the base station with second data flow as main flow, and with first data flow as auxilliary stream, and the value of the CQI of terminal through detecting each data; Still identifying first data flow is main flow; Second data flow is auxilliary stream, and adopts the control information of second data flow that the base station sends first data flow of going to decode, and adopts the control information of first data flow that the base station sends second data flow of going to decode; Thereby cause decoding error, can't obtain correct business datum.
To sum up, in the existing FDD system, there is base station and terminal problem, thereby makes the terminal correctly to decode data flow to the control information identification error of each data flow of mutual transmission.
In addition, the base station uses public guide frequency to send data flow under the FDD system, and the terminal utilizes public guide frequency that the data flow that receives is carried out channel estimating, obtains the metrical information of two data flow.And at time division duplex (TDD; Time Division Duplexing) adopt dedicated pilot to send data flow in the system; The terminal utilizes dedicated pilot that the data flow that receives is carried out channel estimating; And the TDD system is in the standardized process at present, does not also have clear and definite terminal and base station how correctly to identify the control information of each data flow of mutual transmission.

That is to say; Which data flow which dedicated pilot is used to transmit is that base station and terminal consult to confirm good in advance; Therefore; The terminal just can utilize dedicated pilot to identify each data flow, because the employed dedicated pilot of each data flow is different, thereby has guaranteed to utilize the correctness of dedicated pilot recognition data stream.
Provide concrete explaining below.
When the embodiment of the invention is set up in the sub-district; Be basic intermediate code of each cell allocation (Midamble sign indicating number); Each Midamble sign indicating number can have a plurality of displacements, and each displacement can be distributed to different users, also can distribute to same user's different data flow.The displacement of Midamble sign indicating number just is equivalent to dedicated pilot, is used to carry out channel estimating etc.
The number of supposing the data flow of descending transmission is N, then need be M Midamble sign indicating number displacement of N data flow distribution, and wherein M can not can think a plurality of Midamble sign indicating number displacements of data flow distribution less than N.
Base station and terminal consult to confirm the position of control information in same control signaling of a plurality of data flow in advance, and there is corresponding relation (hereinafter to be referred as first corresponding relation) in the position of the control information of promptly any data flow and this data flow in the control signaling.For example; As shown in Figure 2; Comprise the resource allocation control information of a plurality of data flow in the resource allocation control signaling in descending control signaling; Can set corresponding first data flow of control information on the primary importance, corresponding second data flow of the control information on the second place ... the corresponding N data flow of the locational control information of N.
And base station and terminal also will consult to confirm as the Midamble sign indicating number displacement (being dedicated pilot) of each distribution of flows in advance, promptly also have corresponding relation (hereinafter to be referred as second corresponding relation) between each Midamble sign indicating number displacement and the data flow.In the embodiment of the invention, can identify each dedicated pilot with digital number, for example, when the displacement of data flow and Midamble sign indicating number is when concerning one to one; When being M=N, sequence number is the transmission that the Midamble sign indicating number displacement of i is used for the i data flow, i=1 wherein, 2; 3 ..., N.When corresponding two the Midamble sign indicating numbers displacement of data flow, promptly during M=2N, can be with the Midamble sign indicating number displacement of adjacent sequence number as one group; Be that sequence number is the transmission that the Midamble sign indicating number displacement of 2i-1 and 2i is used for the i data flow, perhaps, correspondence is in groups one by one with the first half sequence number and half sequence number of back; Be sequence number be i with sequence number be the transmission that the Midamble sign indicating number displacement of N+i is used for the i data flow, i=1 wherein ...; N; In addition, the corresponding relation of a variety of Midamble sign indicating number displacements and data flow can also be arranged, enumerate no longer one by one here.
The above-mentioned digital number that is used to identify different dedicated pilots can just define in standard in advance, and equipment vendor directly produces just passable when production equipment by standard, such as in the TD-SCDMA system; Dedicated pilot is the displacement (shift) of Midamble sign indicating number, representes the displacement of Midamble sign indicating number with shift, then when shift=1; The displacement of expression Midamble sign indicating number once when shift=2, is represented twice of Midamble sign indicating number displacement; By that analogy, when shift=N, expression Midamble sign indicating number displacement N time; Wherein, the number of chips of the each displacement of Midamble sign indicating number is according to parameter configuration.
Base station and terminal are stored into these two kinds of corresponding relations in base station and the terminal after consulting to have confirmed first corresponding relation and second corresponding relation in advance.Descending control signaling is at first set up according to first corresponding relation in the base station; And pass through down control channel---High-Speed Shared Control Channel (HS-SCCH; High Speed SharedControl Channel) sends this descending control signaling to the terminal, comprising resource allocation (time-slot code channel etc.) signaling of each data flow, transformat (TBS and modulation system) signaling, HARQ signaling etc.
The terminal receives the descending control signaling that down control channel (HS-SCCH) is gone up transmission, utilizes first corresponding relation, the control information of follow-up each data flow that will receive of identification from descending control signaling.For example; As shown in Figure 2; Utilize first corresponding relation; Distribute the control signaling from downlink resource, the control information on the primary importance is regarded as the resource allocation control information of first data flow, the control information on the second place is regarded as the resource allocation control information of second data flow ... the locational control information of N is regarded as the resource allocation control information of N data flow.
When descending a plurality of data flow is sent in the base station,, will insert in the corresponding data flow for the Midamble sign indicating number displacement of each distribution of flows, and this data flow will be sent to the terminal according to second corresponding relation.
The terminal receives descending a plurality of data flow; According to second corresponding relation; From a plurality of data flow that receive, identify each data flow, and the Downlink Control Information of each definite data flow detects the corresponding data flow of decoding before utilizing, obtain the business datum of each data flow.
Wherein, it is multiple that the terminal confirms that the mode of the pairing Midamble sign indicating number displacement of each data flow can have, and a kind of mode is to utilize high-rise configuration, and promptly high level can be the pairing Midamble sign indicating number displacement of each data flow of terminal configuration; Another kind of mode is the configuration mode of acquiescence; Corresponding relation between displacement of Midamble sign indicating number and the code channel resource promptly is set in advance; Corresponding Midamble sign indicating number displacement can be learnt according to the code channel information from the resource allocation signal that control channel receives in the terminal so, thereby utilizes the displacement of Midamble sign indicating number to confirm corresponding data flow.
After the terminal obtains the business datum of each data flow; Through up FEEDBACK CONTROL channel---high-speed shared information channel (HS-SICH; High Speed Shared Information Channel) sends up feedback control signaling to the base station, comprising the ACK/NACK signaling of each data flow, CQI signaling etc.In control information when ordering of every part signaling being carried out a plurality of data flow, can use in advance first corresponding relation of appointing with the base station.
The base station utilizes first corresponding relation when receiving the up feedback control signaling of ascending control channel HS-SICH transmission, identify the pairing up feedback control information of each data flow.
