Description
Technical field
The present invention relates to digital communication technology, refer to a kind of method and system of obtaining the multicarrier confirmed/non-confirmed information under the big broadband especially.
Background technology
Senior international mobile communication (IMT-Advanced, International Mobile communicate-Advanced) system can realize the high-speed transfer of data, and have 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; 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 requirement of senior International Telecommunications Union (ITU-Advanced), as Long Term Evolution (LTE, senior Long Term Evolution (the LTE-Advanced of evolution standard Long Term Evolution), Long Term Evolution Advanced) system, need to 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 (CA, carrier aggregation) 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.
In the LTE-A system after having adopted the spectrum aggregating technology, upstream bandwidth and downlink bandwidth comprise a plurality of component carriers respectively, at this moment physical layer ascending control channel (PUCCH, physical uplink control channel) needs affirmation/non-affirmation (ACK/NACK) information of a plurality of downlink component carriers of feedback.Usually the base station has a descending carrier maximum number M that can dispose, for general three kinds of ACK, NACK of existence of the corresponding feedback states of the physical layer descending Traffic Channel (PDSCH) of each downlink component carrier of actual disposition and discontinuous posting a letter (DTX), wherein, ACK represents that UE correctly receives data; NACK represents that UE receives error in data; DTX represents to cause UE not receive data because physical layer descending control channel (PDCCH) or PDSCH lose, and is DTX for its feedback states of the descending carrier that is not configured.
In order to feed back these ACK/NACK information, a kind of direct method is exactly to feed back the ACK/NACK information of a plurality of descending carriers on each up-link carrier respectively, this method is fairly simple, can keep compatibility well with LTE, but, because up have a plurality of PUCCH channels to transmit simultaneously, destroyed uplink single-carrier property, and then reduced feedback performance.To this, a lot of solutions have been proposed at present, such as, after the ACK/NACK information of a plurality of descending carriers bundled operation, on single PUCCH channel, feed back again, this binding mode since the channel condition of each carrier wave differ may be bigger, therefore, the method that the ACK/NACK information binding of a plurality of descending carriers is fed back has seriously reduced the throughput of system.For another example, utilize different modulation symbol on different PUCCH channels and this channel to represent the method for the different feedback states of all carrier waves, be also referred to as the method that channel is selected.The method that this channel is selected is owing to only feed back on a PUCCH channel, therefore there is not the problem of destroying single-carrier property, the throughput decline problem of having avoided binding method to bring simultaneously, but, the method that channel is selected only can be used for the smaller situation of descending carrier number, and is bigger for the descending carrier number, as greater than 4 situation, because optionally the number of channel is limited, makes this method can't accurately feed back the HARQ-ACK feedback information of all descending carriers.
The method of another feeding back ACK/nack message is that the mode that adopts LTE to feed back CQI is fed back multicarrier HARQ-ACK method, promptly the ACK/NACK information of needs feedback is carried out respective coding modulation back and adopts PUCCH form 2 to feed back.But it is the same with binding method, this method also needs UE can detect DTX, if feedback bits and corresponding downstream component carrier (DL CC) with ACK/NACK that simultaneously can not be correct associate, ACK/NACK information just equals mistake so, has also just lost the meaning of feeding back ACK/nack message.
From the method for above-mentioned existing transmission ACK/NACK information, or reduce the throughput of system, or can not guarantee correct feeding back ACK/nack message, reduced feedback performance.
