Description

Transmission method, user equipment and the base station of mixed automatic retransfer response message Technical field
The present embodiments relate to the communication technology more particularly to a kind of transmission method, user equipment and the base stations of mixed automatic retransfer response message.
Background technique
Long term evolution (Long Term Evolution, abbreviation LTE) it is by third generation partner program (The 3rd Generation Partnership Project, abbreviation 3GPP) Universal Mobile Communication System (the Universal Mobile Telecommunications System that organizes to set up, UMTS) the long term evolution of technical standard, which introduce orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, abbreviation OFDM) and multiple-input and multiple-output (Multi-Input&Multi-Output, letter Claim MIMO) etc. key technologies, significantly increase spectrum efficiency and message transmission rate, obtained extensive development in recent years.
LTE system downlink and uplink is based respectively on orthogonal frequency division multiplexing multiple access (Orthogonal Frequency Division Multiplexing Access, abbreviation OFDMA) and single carrier frequency division multiplexing multiple access (Single Carrier-Frequency Division Multiplexing Access, abbreviation SC-FDMA), the subcarrier on OFDM or SC-FDMA symbol (calling time-domain symbol in the following text) and frequency domain dimension that running time-frequency resource is divided into time-domain dimension, and the smallest resource granularity is called a resource unit (Resource Element, abbreviation RE), indicate one in time-domain The time-frequency lattice point of a sub- carrier wave composition in time-domain symbol and frequency domain.The transmission of business is dispatched based on base station (Evolved NodeB, abbreviation eNB) in LTE system, and the basic time unit of scheduling is a subframe, and a subframe includes multiple time-domain symbols.Specific scheduling flow is that base station sends control channel, such as Physical Downlink Control Channel (Physical Downlink Control Channel, abbreviation PDCCH) or enhancing Physical Downlink Control Channel (Enhanced PDCCH, abbreviation EPDCCH), the control channel can carry Physical Downlink Shared Channel (Physical Downlink Shared Channel, abbreviation PDSCH) or Physical Uplink Shared Channel (Physical Uplink Shared Channel, abbreviation PUSCH) scheduling information, the scheduling information includes resource allocation information, adjust the control information such as coding mode.User equipment (User Equipment, abbreviation UE) detects control channel in subframe, and according in the control channel detected The scheduling information of carrying carries out the reception of downstream data channel or the transmission of uplink data channels.
LTE supports frequency division duplex (Frequency Duplexing Division, abbreviation FDD) and two kinds of duplex modes of time division duplex (Time Duplexing Division, abbreviation TDD).For FDD, downlink and uplink is transmitted on different carrier waves.For TDD system, uplink and downlink are transmitted in the different time of same carrier wave, specifically include downlink subframe, sub-frame of uplink and special subframe on the carrier wave.LTE currently supports 7 kinds of different TDD uplink-downlink configurations.
LTE uses hybrid automatic repeat-request (Hybrid Automatic Repeat Request, abbreviation HARQ) mechanism realize error-detection error-correction function, following behavior example, after UE receives PDSCH, if receiving correct, UE feedback acknowledgment (ACKnowledge on PUCCH, abbreviation ACK), if incorrect, fed back on PUCCH and do not confirm (NACKnowledge, abbreviation NACK).LTE also supports carrier wave to polymerize (Carrier Aggregation, abbreviation CA) technology, i.e. multiple carrier waves are allocated to a UE to promote the data rate of UE by base station.It is synchronous transmission when carrying out CA, on multiple subcarrier times that base station is sent, UE can detect the PDCCH and corresponding PDSCH for dispatching each carrier wave respectively, wherein the specific detection process of each carrier wave is similar with above-mentioned single carrier case.LTE system supports FDD CA, TDD CA and FDD+TDD CA.For TDD CA, and it is divided into the TDD CA of identical uplink-downlink configuration and the TDD CA of different uplink-downlink configurations.There are a main carrier and at least one secondary carrier under CA mode, and loading ACK/NACK PUCCH is only sent on the main carrier of UE.PUCCH sending mode under CA mode includes 3 both of which of channel selection modes and PUCCH format, wherein, under channel selection modes, ACK/NACK feedback is carried out using PUCCH format 1a/1b, but channel selection modes could support up the CA of two carrier waves, and 3 mode of PUCCH format uses the transmission structure of DFT-S-OFDM, can at most support 20 ACK/NACK transmission.
However, with the continuation evolution of LTE technology, in the scene for supporting 32 carrier waves to be polymerize, by taking the polymerization of TDD-FDD carrier wave as an example, wherein TDD carrier wave is main carrier, and uplink-downlink configuration is 5, other carrier waves are FDD carrier wave, the number for the maximum ACK/NACK for so needing to feed back on a uplink main carrier is 9+10*31=319, and under normal conditions, the transmission power of user equipment is certain, it can't increase as the number of descending carrier increases, when the number for the HARQ-ACK for needing to send increases, in the case where user uplink power limited, the performance of HARQ-ACK can decline as the number of HARQ-ACK increases, the downlink data that can have user can support the reception of 32 carrier waves, but uplink is but not The HARQ-ACK of respective number can be fed back.

For example, assuming that the first mixed automatic retransfer response message is 101101100, wherein the number of the corresponding carrier wave of the response message of each is respectively 0,2,3,5,6,8,9,11,13, wherein, the number of main carrier is 0, corresponding response message is 1, with carrier wave grouping information for (1；1,2,3), (2；4,5,6), (3；7,8,9), (4；10,11,12), (5；14, 15) it illustrates, it is not counted in carrier wave grouping according to carrier wave grouping information main carrier, the number of carrier wave is 2, 3 be one group, the number of carrier wave is 5, 6 be one group, the number of carrier wave is 8, 9 be one group, the number of carrier wave is 11, 13 be one group, logical AND operation so is carried out to the response message of the corresponding Physical Downlink Shared Channel of the first Downlink Control Information described in the grouping of same carrier wave and generates third mixed automatic retransfer response message, as 0, 0, 1, 0, everybody number of corresponding carrier wave grouping is respectively 1, 2, 3, 4, the 4th mixed automatic retransfer response message generated after being ranked up according to the number that carrier wave is grouped to third mixed automatic retransfer response message is 10010.It should be noted that the sequence can be with Ascending order, or descending is also possible to be ranked up with certain rule, herein not in this, as limitation.The response message 1 of the Physical Downlink Shared Channel according to corresponding to main carrier and the 4th mixed automatic retransfer response message generate mixed automatic retransfer response message, which is 10010.
On the basis of two kinds of specific implementations of above-mentioned user equipment embodiment one and embodiment one, further, the processing module 12 of user equipment is used to distribute sum according to the downlink, the downlink distribution index of each first Downlink Control Information and the corresponding Physical Downlink Shared Channel of each first Downlink Control Information generate the first mixed automatic retransfer response message, it is specifically as follows: generates the response message of the corresponding Physical Downlink Shared Channel of each first Downlink Control Information according to the decoding correctness of the corresponding Physical Downlink Shared Channel of each first Downlink Control Information respectively；Acquisition ranking results are ranked up to the downlink distribution index of each first Downlink Control Information, the second Downlink Control Information is determined according to the ranking results and downlink distribution sum, and the downlink distribution index of second Downlink Control Information is obtained, the response message of the corresponding Physical Downlink Shared Channel of second Downlink Control Information is not confirm NACK；The first mixed automatic retransfer response message is generated according to the response message of the response message of the corresponding Physical Downlink Shared Channel of each first Downlink Control Information and the corresponding Physical Downlink Shared Channel of second Downlink Control Information, the discharge sequence of the response message of the response message and corresponding Physical Downlink Shared Channel of second Downlink Control Information of the corresponding Physical Downlink Shared Channel of each first Downlink Control Information in the first mixed automatic retransfer response message, it is identical as the sequence of downlink distribution index of each first Downlink Control Information and second Downlink Control Information.
I.e. specifically, how according to according to downlink distribution total (Total DAI) and downlink distribution index (Downlink Assignment Index, abbreviation DAI) generate the first mixed automatic retransfer response message (the first HARQ-ACK) corresponding to the PDCCH/ePDCCH of all PDSCH in same carrier set and/or indicating downlink SPS release, user equipment is according to downlink distribution sum and downlink distribution index to determine whether there is PDCCH missing inspection, it should be noted that the first Downlink Control Information and the second Downlink Control Information are Downlink Control Information DCI, here with the first and second Downlink Control Information normally received only for differentiation and missing inspection, indicated under missing inspection with the second Downlink Control Information Row control information.For example, user equipment receives 5 DCI, and the DAI of each DCI is respectively 3, Isosorbide-5-Nitrae, 6,7, and the downlink distribution sum received is 9, then generating response message according to the decoding correctness of PDSCH corresponding to the DCI received first, it is assumed that decoding is correct, then response message is 1, is then ranked up to the DAI of the DCI received, ranking results are 1,3,4,6,7, it is corresponding HARQ-ACK is 11111, HARQ-ACK at this time does not include the response message of missing inspection information, the method of the embodiment of the present invention is according to ranking results and downlink distribution sum 9, it can determine that downlink distribution index is 2,5,8,9 Downlink Control Information missing inspection, the response message of the Downlink Control Information of the missing inspection is 0, then generating the first HARQ-ACK according to the response message of the Downlink Control Information of non-missing inspection and the Downlink Control Information of missing inspection, the first HARQ-ACK is 101101100.From the example above it is appreciated that PDCCH missing inspection can distribute sum by downlink to judge, and it may determine that the position of specific missing inspection according to DAI.
Further, the carrier wave grouping information is what the base station was generated according to the data carrying capabilities of downlink traffic and Physical Uplink Control Channel.
It can thus be appreciated that, user equipment can distribute sum and downlink distribution index by the downlink received to determine the Downlink Control Information of itself missing inspection, so as to ensure that the mixed automatic retransfer message bit number comprehension between base station is consistent, the codebook size for being sent to the mixed automatic retransfer message of base station further can also be flexibly controlled according to the carrier wave grouping information that base station is sent.
Through the foregoing embodiment it is understood that, all carrier waves to user device configuration are divided into several carrier wave groupings, HARQ-ACK corresponding to each carrier wave of the same carrier wave grouping can carry out bundling operation (logical AND operation), the HARQ-ACK of intercarrier between group cannot do bundling operation, main carrier does not carry out bundling operation with any subcarrier, and main carrier oneself is a group in other words.
Main carrier is not bundled with the HARQ-ACK of other carrier waves, it is because main carrier transmission is all the important control information of the user equipment, if the HARQ-ACK with other carrier waves is bundled, it is very possible because other carrier waves data always decoding error, lead to HARQ-ACK always NACK, logically with operation, HARQ-ACK after binding is just NACK, the data of so main carrier are also required to ceaselessly retransmit, and much controlling information is to have certain time window, such as random access response, the order etc. of timing advance, so as to cause step-out, it further may result in needs to restart, data outage, influence the service feature of user equipment.
HARQ-ACK in carrier wave grouping can be bundled, the reason is that the channel quality of some carrier waves is similar, such as interference environment is similar, it such as is all strongly disturbing carrier wave, the carrier wave of the e.g. same carrier band is divided into a group, it such as is all that unauthorized carrier wave is divided into a group, a such as remote radio head (Remote Radio Head, abbreviation RRH) inside all carrier waves be divided into a group, so they are simultaneously the probability of ACK or NACK with regard to bigger, so unnecessary re-transmission will be fewer, and the influence to the handling capacity of downlink is also just smaller.
