Abstract
The invention discloses a multiplexing method of scheduling request messages and correct and wrong answer messages. The multiplexing method comprises the following steps of: carrying out joint encoding on bit information corresponding to the scheduling request messages and bit information corresponding to the correct and wrong answer messages; and transmitting the bit information subjected to the joint encoding by using a format 2 of a physical uplink control channel (PUCCH). The multiplexing method correctly feeds back ACK (Acknowledgement Character)/NACK (Negative Acknowledgement) answer message effects that correspond to all downlink component carriers when simultaneously transmitting the scheduling request messages and the answer messages.
Description
Technical field
The present invention relates to the communications field, in particular to the multiplexing method of a kind of scheduling request information and correct and wrong answer.
Background technology
At present, the develop rapidly of digital communication system is had higher requirement to reliability of data communication.Yet under some mal-condition, especially under high data rate or high-speed mobile environment, multipath interference and Doppler frequency shift etc. seriously affect systematic function.Therefore, effective error-control technique, especially mixing automatic request retransmission (HybridAutomatic Repeat Request abbreviates HARQ as) technology just becomes the research focus of the communications field.
At long evolving system (Long Term Evolution, abbreviate LTE as) descending HARQ in, as terminal (User Equipment, abbreviate UE as) there is not a Physical Uplink Shared Channel (Physical Uplink Shared Channel, abbreviate PUSCH as) time, Physical Downlink Shared Channel (Physical Downlink Shared Channel, abbreviate PDSCH as) correct and wrong (Acknowledgement/Negative Acknowledgement, abbreviate ACK/NACK as :) response message is to go control channel (PhysicalUplink Control Channel abbreviates PUCCH as) physically to go up and send.LTE has defined multiple PUCCH form (format), comprise PUCCH format1/1a/1b and format2/2a/2b, wherein format1 is used for sending dispatch request (the Scheduling Request of UE, abbreviate SR as) message, format 1a and 1b are used for feeding back the ACK/NACK response message of 1 bit and the ACK/NACK response message of 2 bits respectively.
Fig. 1 is when adopting the regular circulation prefix according to subframe in the LTE system of correlation technique, the schematic diagram of PUCCH form 2, as shown in Figure 1, the time-frequency bidimensional system in, a subframe is one millisecond, a time slot is 0.5 millisecond.
Fig. 2 is when adopting extended cyclic prefix according to subframe in the LTE system of correlation technique, the schematic diagram of PUCCH form 2, as shown in Figure 2, the time-frequency bidimensional system in, a subframe is one millisecond, a time slot is 0.5 millisecond.
In the LTE system, at Frequency Division Duplexing (FDD) mode (Frequency Division Duplex, abbreviate FDD as) in, because ascending-descending subframes is one to one, so when PDSCH only comprises a transmission block, UE will feed back the ACK/NACK response message of 1 bit, and when PDSCH comprised two transmission blocks, UE will feed back the ACK/NACK response message of 2 bits.
In the LTE system, at time division duplex (Time Division Duplex, abbreviate TDD as) in, because ascending-descending subframes is not one to one, the ACK/NACK response message that is to say a plurality of descending sub frame correspondences need send on the PUCCH of sub-frame of uplink channel, and wherein " bundlingwindow " formed in the set of the descending sub frame of sub-frame of uplink correspondence.
The sending method of ACK/NACK response message comprises following two kinds:
A kind of method is binding (bundling), and the core concept of this method is carrying out logic and operation in the ACK/NACK response message of the transmission block of each descending sub frame correspondence of this sub-frame of uplink feedback.If each subframe has only a transmission block, then UE will feed back the ACK/NACK response message of 1 bit; If a descending sub frame has 2 transmission blocks, then UE will feed back the ACK/NACK response message of 2 bits.
Another kind method is that channel is selected (multiplexing with channel selection, be called for short multiplexing), the core concept of this method is to utilize different modulation symbol on different PUCCH channels and this channel to represent the different feedback states of the descending sub frame that need feed back at this sub-frame of uplink.If a plurality of transmission blocks are arranged on the descending sub frame, elder generation carries out the ACK/NACK of a plurality of transmission blocks feedbacks of descending sub frame to carry out the channel selection again behind the logical AND (being also referred to as spatialbundling) so, uses PUCCH format1b to send then.
Therefore, in LTE FDD system, when UE need send SR and ACK/NACK response message simultaneously, when sending negative SR (not needing to carry out dispatch request), UE was distributing to transmission ACK/NACK response message on its ACK/NACK PUCCH resource; (need to carry out dispatch request) in the time will sending positive SR, UE is distributing to transmission ACK/NACK response message on its SR PUCCH resource.
In the TDD system, when UE need send SR and ACK/NACK simultaneously, when sending negative SR (not needing to carry out dispatch request), UE is distributing to transmission bundled ACK/NACK or multipleACK/NACK signal on its ACK/NACK PUCCH resource; In the time will sending positive SR, (need to carry out dispatch request), UE sends dibit information b (0) b (1) at the PUCCH format1b that distributes to employing table 1 definition on its SR PUCCH resource, and wherein the value of b (0) b (1) will be according to the U that has passed through spatialbundling

At senior international mobile communication (International MobileTelecommunications-Advanced, abbreviate IMT-Advanced as) in the system, can realize the high-speed transfer of data, and has a bigger power system capacity, under the situation about move at low speed, focus covering, the peak rate of IMT-Advanced system can reach 1Gbit/s, and under the situation that high-speed mobile, wide area cover, the peak rate of IMT-Advanced system can reach 100Mbit/s.
In order to satisfy (the International TelecommunicationUnion-Advanced of senior International Telecommunications Union, abbreviate ITU-Advanced as) requirement, senior Long Term Evolution (Long Term Evolution Advanced as the evolution standard of LTE, abbreviating LTE-A as) system need support bigger system bandwidth (reaching as high as 100MHz), and need the existing standard of backward compatibility LTE.On the basis of prior LTE system, the bandwidth of LTE system can be merged and obtain bigger bandwidth, this technology is called carrier aggregation (Carrier Aggregation, abbreviate CA as) technology, the availability of frequency spectrum, alleviation frequency spectrum resource that this technology can improve the IMT-Advance system are in short supply, and then optimize the utilization of frequency spectrum resource.
After introducing carrier aggregation, in downlink component carrier and PDSCH transmission block and the HARQ process relation, a groundwork supposition is when not adopting space division multiplexing, a corresponding PDSCH transmission block of downlink component carrier and a HARQ process, that is to say that UE need feed back the ACK/NACK response message of 1 bit for a PDSCH transmission block of each component carrier.When adopting space division multiplexing, the current regulation of LTE-A is supported 2 transmission blocks at most.Therefore, when adopting space division multiplexing, UE need feed back the ACK/NACK response message of 2 bits for 2 PDSCH transmission blocks of each downlink component carrier.
In the LTE-A system after having adopted the spectrum aggregating technology, upstream bandwidth and downlink bandwidth just can comprise a plurality of component carriers.When the base station all has scheduling to give the PDSCH of certain UE on a plurality of downlink component carriers, and when UE when current subframe does not have PUSCH to send, terminal need be fed back the ACK/NACK response message that the PDSCH of these a plurality of downlink component carriers transmits on PUCCH.A current work supposition is that these ACK/NACK response messages are the upstream components carrier wave transmissions by a UE-specific.For SR message, a current work supposition is that UE only sends a SR, and this SR message is the upstream components carrier wave transmission by a UE-specific.
Therefore, in the LTE-A system, if when UE need send SR message and ACK/NACK response message simultaneously on a up-link carrier, the situation that exists a plurality of ACK/NACK response messages and SR message needs to send simultaneously.And if this situation is directly continued to use the method in the LTE TDD system, because the correlation between the component carrier does not have the correlation between the subframe strong, can not correctly obtain the ACK/NACK response message of each downlink component carrier, thereby reduce the throughput of system.
