At 3GPP (Third Generation Partnership Project; Third generation partner program) in LTE (Long Term Evolution,, the Long Term Evolution) system; Introduced SPS (Semi-Persistent Scheduling; Semi-continuous) scheduling mechanism, semi-continuous scheduling uses as VoIP is professional to specific transactions.The working method of semi-continuous scheduling is: to particular data packet, the initial transmission employing continuous dispatching like the professional voice packets of VoIP retransmits and adopts dynamic dispatching to combine with continuous dispatching.The difference of continuous dispatching and dynamic dispatching is whether need use the control command indication, and control command is then carried by PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel).
Continuous dispatching is meant that the base station gives certain professional allocation of packets fixed resource, for example time, frequency, code channel etc., and specify fixing transformat, packet sends with the regulation transformat in the allocated resource position, need not dispatch.In LTE, the base station is through the appearance cycle of RRC (Radio Resource Control, Radio Resource control) signaling indication persistent resources; The frequency location of specifying continuous dispatching through special control order in continuous dispatching at first and transformat etc. in the cycle that follow-up continuous dispatching packet is indicated according to this starting point and RRC signaling, are pressed the format receiving data bag of this control command appointment;, i.e. downlink communication, or transmission packet; Be uplink communication, no longer need the control command indication.This special control order has two effects: 1) activate continuous dispatching, specify continuous dispatching starting point and form; 2) dispatch first packet, being equivalent to first packet is dynamic dispatching.Dynamic dispatching is meant the base station must first these data of transmitting control commands indication UE will with which kind of transformat be sent, and UE receives or send packet according to control command on which resource before sending data.

The present invention proposes a kind of confirming scheduling resource release method, may further comprise the steps: user equipment (UE) receives the release command and the Physical Downlink Shared Channel PDSCH data of the persistent scheduling resource of sending the base station; According to the release command and the said PDSCH data of the said persistent scheduling resource of receiving, said UE calculates the resource number of the PUCCH that sends confirmation; Said UE sends confirmation on selected PUCCH resource.
For the ease of understanding the technical scheme that the present invention proposes, be necessary to introduce the feedback mechanism of acknowledge message in the LTE system.
In the LTE system; When having opened HARQ (Hybrid Automatic RepeatRequest mixes automatic repeat requests) function in the downlink transfer, UE is after having accomplished demodulation to the data on the descending sub frame n ', decoding; The signaling that will whether need retransmit in the last data on this descending sub frame of base station feedback of sub-frame of uplink n=n '+k; Be ACK/NACK (Acknowledge/Not Acknowledge confirms/deny) information, wherein ACK is with ' 1 ' expression; Expression data this moment correctly receive, and do not need to retransmit; NACK is with ' 0 ' expression, and expression data decoding mistake this moment needs to retransmit.For FDD system, k=4.For the TDD system, k ∈ K, the value of set K is numbered relevant, as shown in table 1 with the uplink-downlink configuration of system and concrete subframe:
Descending relative set K among the table 1:TDD
At this moment; A plurality of radio frames sequence arrangement, even last subframe is k among the radio frames a, then first subframe is k+1 among the radio frames a+1; Last table only with a radio frames be example provided each sub-frame of uplink institute for the situation of K, wherein the descending sub frame in the last radio frames item is represented in n-k＜0.For example, for the subframe numbering 2 of uplink-downlink configuration 0, relevant numerical is 6 in the table, 2-6=-4, and the feedback information of the descending sub frame 6 in the promptly last radio frames sends in current subframe 2.
When system carries out many code words (code word) transmission, through the usage space multiplex technique, will be on same physical resource, multiplexing transmission belongs to same user's multiplex data stream.In one sub-frame, the data on the different data flow will independently be encoded, and become code word.The ACK/NACK information of feedback will produce based on code word this moment, promptly to obtaining independently ACK/NACK information of 1 bit behind each codeword decoding.
Use BPSK or QPSK that the ACK/NACK feedback information is modulated in the system; And can only carry a modulation symbol in each sub-frame of uplink at most; This symbol is through modes such as twice spread spectrums; Promptly use earlier cyclically shifted sequences on frequency domain, to carry out spread spectrum, re-use orthogonal sequence and on time domain, carry out spread spectrum, after becoming a single carrier after the processing and broadcasting signal; In the feedback channel of appointment, transmit, a plurality of users' ACK/NACK transmits on identical physical resource through the mode of sign indicating number branch is multiplexing in the sub-district.
For different systems and configuration; In order to guarantee that the ACK/NACK on each descending sub frame can both be transmitted; And do not destroy the single-carrier property of uplink; Then need merge processing to a plurality of ACK/NACK feedback informations, as, the ACK/NACK on a plurality of descending sub frames is merged into an ACK/NACK, the ACK/NACK of a plurality of code words in the descending sub frame is merged into an ACK/NACK.For example; Under the TDD communication mode, the ACK/NACK of a plurality of descending sub frames need be in the configuration of same sub-frame of uplink feedback, and is as shown in table 1; Subframe numbering 2 for uplink-downlink configuration 2; Relevant numerical is 8,7,6,4 in the table, and the feedback information of the descending sub frame 4,6,7,8 in the promptly last radio frames sends in current subframe 2.In addition, in order to guarantee the comparatively reliable detection performance that has of feedback signaling, the feedback information of transmission can not surpass 2 bits in each sub-frame of uplink, and the promptly the highest QPSK that can only use modulates.
When the descending control signaling transmission is carried out in the base station; Can distribute exclusive resource for each user; But feedback transmission for uplink ACK/NACK; The user does not know that other users use channel situation, for fear of the user resource contention takes place when feeding back, and the UE that feeds back will be according to the resource number n of its descending control signaling that receives

There are two kinds of different uplink ACKs/NACK feedback methods down in the LTE system TDD mode at present.
(1) ACK/NACK merges (Bundling) transmission.After ACK/NACK in the M sub-frame carried out logic add, obtain one group of compound ACK/NACK information, obtain a symbol, carry out processing such as " twice spread spectrums " again, use specific up channel to transmit through modulation.In merging transmission, merge and carry out based on code word.Wherein in the numbering of up channel and this M sub-frame, the descending control signaling resource number that belongs to this user on actual employed first subframe of user is bound.For same user; The base station can only detect one group of ACK/NACK at most in a sub-frame of uplink; And will carry out identical processing: reaching maximum retransmission (comprising first transmission) before to the data on the M sub-frame that merges; Occur decoding error or loss of data on arbitrary subframe, then the data on the M sub-frame all will retransmit; If when the M sub-frame all correctly receives, then need not retransmit.
(2) ACK/NACK multiplexing (multiplexing) transmission.ACK/NACK on a plurality of code words in each subframe is carried out obtaining a compound ACK/NACK after the logic add; Obtain 2 bit feedback information b (0) according to the concrete situation of each descending sub frame; B (1) is to b (0), after b (1) carries out QPSK modulation and obtains a modulation symbol; Again it is carried out processing such as " twice spread spectrums ", and select suitable up channel to transmit.For M descending sub frame all exist one with its unique corresponding channel number n
UL, m, m ∈ 0,1 ..., M-1}.UE need be chosen in different channel numbers according to the concrete condition of feedback information, transmit 2 bit feedback information b (0), b (1); B (0), the value of b (1) is also relevant with the concrete condition of feedback information, is 2 to 4 situation for M; To shown in the table 4, wherein N/A representes also not define like table 2.This method of concrete use does; The base station can detect M the ACK/NACK state that belongs to same UE; Therefore can handle respectively the data on this M sub-frame: during many codeword transmission, the data that belong to different code words in the same subframe will be carried out identical processing; Data on the different subframes can independently retransmit.
