Description
Technical field
The present invention relates to communication technical field, be meant a kind of collocating uplink control resource especially, and the transmission method of ascending control information and device.
Background technology
For long-term evolution multi-carrier system, for supporting that (such as 100MHz, a kind of possibly be the frequency spectrum that directly distributes the 100M bandwidth, as shown in Figure 1 for Long Term Evolution, LTE) the wideer system bandwidth of system than Long Term Evolution; A kind of possibly be with distributing to some spectrum aggregatings of existing systems, gathers into big bandwidth and supplies with long-term evolution multi-carrier system and use, and promptly the user may take M >=1 carrier wave and carries out downlink transfer, and N >=1 carrier wave carries out uplink, and is as shown in Figure 2.
The basic transmission plan of the LTE system (R8 system) of completion is following basically for standardization effort at present: FDD (Frequency Division Duplex; FDD) system and time division duplex (Time DivisionDuplexing; TDD) respectively like Fig. 3 a, shown in the 3b.For each work carrier wave; Defined downlink signaling, downlink data, up signaling and upstream data respectively, and transmission relation each other, wherein; The two ends of upstream control signaling band occupancy; Use the frequency hopping mode to transmit, in two time slots in a sub-frame, upstream control signaling will take different band transmissions.
When the user on a descending sub frame, when taking M descending carrier and carrying out transfer of data, processing such as the data on each descending carrier will independently be encoded, modulation.When system configuration mix automatic repeat requests (Hybrid Automatic Repeat reQuest, when HARQ) retransmitting, terminal (User Equipment; UE) after having accomplished demodulation to the data on this descending sub frame, decoding; Correctly receive according to whether to the affirmative acknowledgement of base station (eNB) feedback (Positive Acknowledgment, ACK) or negative response (Negative Acknowledgment, NACK) (wherein ACK is with ' 1 ' expression; This moment, data correctly received, and did not retransmit; NACK is with ' 0 ' expression, and this moment, the data decoding mistake needed to retransmit), then UE will be to this M of base station feedback ACK/NACK on the sub-frame of uplink of correspondence.For sub-frame of uplink of FDD system corresponding a descending sub frame.For the TDD system, sub-frame of uplink maybe be corresponding a plurality of descending sub frames.
The LTE system; The ascending control channel form that is used for feeding back ACK/NACK is form (format) 1/1a/1b; Wherein format 1/1a uses binary phase shift keying (Binary Phase Shift Keying, BPSK) modulation, format 1b use QPSK (Quadrature Phase Shift Keying; QPSK) modulate, but all can only carry a modulation symbol in the ascending control channel of various forms.The mode that the feedback information of different UEs divides through sign indicating number a Resource Block (Resource Block, RB) in transmission simultaneously.Feed back for ACK/NACK; The spread spectrum code sequence of its use is cyclic shift (cyclicshift; CS) (promptly using length is that 4 Walsh-Hadamard sign indicating number is that each bit in 12 the CS sequence carries out spread spectrum to length for Orthogonal Code, the OC) multiplexed sequence of sequence for sequence and quadrature; As shown in Figure 4, the shift intervals (Δ of cyclically shifted sequences wherein
Shift) span be 1,2,3}, its value is configured by high level.
Be used for demodulation reference symbol (Reference Symbol RS) also will experience the processing procedure similar with data, and its unique difference is that OC is different, and its length is C, the regular circulation prefix (circle prefix, in the time of CP), C=3, during expansion CP, C=2.Therefore Resource Block (Resource Block, RB) in, can distinguish 12/ Δ through the cyclic shift sequence
ShiftIndividual user, RS can distinguish C user, and can distinguish total physical channel quantity is the c12/ Δ
Shift, this value also is that the form that a RB can carry is the upper limit of the ascending control channel of fomat1/1a/1b.
Table 1 has provided Walsh-Hadamard sign indicating number available in the system, and referring to shown in the table 1, the length of orthogonal sequence is 4.
| Sequence index n oc(n s) | Orthogonal sequence [w (0) Λ w (N SF PUCCH-1)] |
| 0 | [+1+1+1+1] |

After UE chooses frequency expansion sequence and treats the feedack symbol and carry out spread spectrum according to the predetermined rule of system; Will be by it being mapped to Physical Resource Block (Physical ResourceBlock in the mode shown in Fig. 6 a and 6b; PRB) transmit on, Fig. 6 a is the sketch map of system transmissions ascending control information under the conventional CP; Be depicted as the sketch map of system transmissions ascending control information under the expansion CP referring to Fig. 6 b.
For the long-term evolution multi-carrier paradigmatic system, the base station will take a plurality of descending carriers and send data to UE in a sub-frame, and all will be an independently HARQ entity on each carrier wave, so UE need feed back a plurality of ACK/NACK information in a sub-frame of uplink.At present also do not form detailed implementation for how feeding back under this kind situation.
If simply reuse existing R8 system definition uplink control signaling feedback system, promptly transmit a plurality of ascending control channels simultaneously.Because single-carrier property is destroyed and a plurality of ascending control channel will be divided total transmitting power equally, so certainly will there be certain loss in the transmitting power on each ascending control channel, will cause the problem of ascending control channel reliability decrease thus.On the other hand; If use the method for existing employed merging of R8 TDD system or multiplexing feedback; Because carrying out logic add, handles the different data block ACK/NACK of institute informational needs; Therefore in a plurality of data blocks any one take defeat after, all are participated in data blocks that ACK/NACK merge and all will retransmit, so will there be loss in system effectiveness.
