Fig. 3 is the flow chart of the information processing method embodiment three under the multi-carrier mode of the present invention, as shown in Figure 3, present embodiment provides a kind of concrete information multiplexing method, present embodiment is described in detail technical scheme of the present invention from the angle of base station and terminal equipment both sides, specifically can comprise the steps:
Step 301, base station generate the grouping information of a plurality of responses, and grouping information is sent to terminal equipment.
In the present embodiment, grouping information is is specifically generated and sent to terminal equipment by the base station, and response is specially the ACK/NACK response.In this step, at terminal equipment before the base station sends uplink feedback information, divide into groups to a plurality of ACK/NACK responses in the base station, the ACK/NACK response is terminal equipment response to base station feedback after the downlink data information that receives the base station transmission, it is feedback to the downlink data transmission correctness, wherein, it is correct that ACK represents that terminal equipment receives data, and NACK represents that terminal equipment receives error in data.Because the feedback of the reception correctness of the data that ACK/NACK response issues the base station for terminal equipment, be that each ACK/NACK response is that each data of issuing with the base station are corresponding, thereby the situation of the ACK/NACK response that will feed back just can be known in the base station before the ACK/NACK response that receives the terminal equipment feedback.Therefore, grouping to a plurality of ACK/NACK responses can initiatively be initiated to carry out by the base station, the number of the downlink data information that the base station can may send at most to terminal equipment according to the base station generates the grouping information of a plurality of ACK/NACK responses, grouping information can be specially group result or rule of classification, group result specifically indicating terminal equipment is divided into one group with which ACK/NACK response, and rule of classification is the foundation of one or more groupings, and terminal equipment is carried out the grouping process of a plurality of ACK/NACK responses again in conjunction with actual conditions according to this rule of classification.Since present embodiment at be the LTE-A system, need feed back a plurality of ACK/NACK responses in the identical up moment, the unnecessary data that causes a CQI channel behind a plurality of ACK/NACK response and the CQI information multiplexing retransmits, generate the grouping information of a plurality of ACK/NACK responses in this step by the base station, and grouping information sent to terminal equipment, especially, this grouping information can send to terminal equipment by proprietary high-level signaling by the base station.
In the above-described embodiments, the base station can be carried out the distribution of CQI channel earlier before a plurality of ACK/NACK responses are divided into groups, and the base station is given terminal equipment by proprietary high-level signaling with the CQI channel notification of distributing usually.In the LTE-A of present embodiment correspondence system, still can adopt the method for channel allocation in the LTE system, can give each downlink member carrier distributing independent CQI channel and feedback cycle parameter of terminal equipment for configuration, also the CQI information of part or all of downlink member carrier can be carried out combined coding, be the identical CQI channel of CQI information distribution behind the combined coding then.In embodiments of the present invention, independent CQI information is carries out behind the combined coding in the CQI of identical CQI channel information, then independent CQI information can only comprise the CQI information of a downlink member carrier, also can comprise the CQI information of a plurality of downlink member carriers.Between two independent CQI information is separate, and their are coding separately separately, and is dispensed on respectively on the different CQI channels and transmits.
In the LTE-A of present embodiment system, when response is divided into groups to a plurality of ACK/NACK,, participate in the ACK/NACK response of the member carrier that a plurality of ACK/NACK responses of grouping can arrive for current scheduling for LTE-A FDD system; For LTE-A TDD system, a plurality of ACK/NACK responses that participate in grouping can be the ACK/NACK response of the current descending sub frame that is dispatched on the member carrier.As shown in Figure 4, in the LTE-A TDD system, for terminal equipment configuration 4 member carrier, and the proportioning of the descending sub frame number of each member carrier and sub-frame of uplink number is 3:2.Be that example describes with a radio frames among the figure, in a radio frames, comprise subframe 0-subframe 9 totally ten subframes, wherein the corresponding constantly part descending sub frame of subframe 0 and subframe 1 is a grey, this grey subframe represent the base station this time be engraved on this descending sub frame terminal equipment dispatched.Because for the base station is all downlink member carriers of terminal equipment configuration, a descending moment, the base station may only be dispatched terminal equipment on the part downlink member carrier therein, and dispatches terminal equipment different being engraved on the different downlink member carriers when descending.A up moment, for LTE-A FDD system, a member carrier has only an ACK/NACK response, and for LTE-A TDD system, a member carrier has a plurality of ACK/NACK responses.As shown in Figure 4, in the up moment of subframe 7, need the ACK/NACK response of the subframe 0 and the subframe 1 of each member carrier of feedback, maximum situations can be fed back two ACK/NACK responses simultaneously, as member carrier 0; Also can feed back an ACK/NACK response, as member carrier 1 and member carrier 3; Also can feed back zero ACK/NACK response, as member carrier 2.Therefore, can to current scheduling to the ACK/NACK response of member carrier divide into groups, perhaps the ACK/NACK response of the current descending sub frame that is dispatched on the member carrier is divided into groups, but because the different member carrier of dispatching constantly can be different with descending sub frame, then for LTE-A FDD system, a plurality of ACK/NACK responses that participate in grouping can be the ACK/NACK response of all member carriers; For LTE-A TDD system, a plurality of ACK/NACK responses that participate in grouping can be the ACK/NACK response of the descending sub frame of all member carriers.It is to be noted, the ACK/NACK that a plurality of ACK/NACK responses that participate in grouping in the present embodiment are all member carriers responds or is the ACK/NACK response of the descending sub frame of all member carriers, and for example the up moment of subframe 7 is that the subframe 0 of member carrier 0～3 and 1 ACK/NACK response are divided into groups in Fig. 4 example.
Further, when divide into groups to a plurality of ACK/NACK responses in the base station, can consider some factors, specifically can come to divide into groups to a plurality of ACK/NACK responses in the base station according to following: the physical layer descending of the number of the grouping situation of a plurality of ACK/NACK responses, transmitting antenna during a terminal equipment feeding back ACK/NACK response, the descending sub frame transfer of data corresponding with a plurality of ACK/NACK responses is controlled the member carrier that signaling is transmitted the place.Be that the member carrier at the physical layer descending control signaling transmission place of the number of the grouping situation of base station a plurality of ACK/NACK responses can be according to the response of a terminal equipment feeding back ACK/NACK time the and/or transmitting antenna and/or the descending sub frame transfer of data corresponding with a plurality of ACK/NACK responses comes a plurality of ACK/NACK are responded and divides into groups.
Particularly, when divide into groups to a plurality of ACK/NACK responses according to the number of the independent CQI information of current sub-frame of uplink feedback in the base station, the group number that the number that a plurality of ACK/NACK responses be divided into the independent CQI information of feeding back with current sub-frame of uplink can be equated, promptly the number of the independent CQI information of ACK/NACK response group after the grouping and current sub-frame of uplink feedback equates.Because information such as the feedback cycle of CQI information and the employed CQI channel of transmission information send to terminal equipment by the base station by proprietary high-level signaling, therefore, base station and terminal equipment all can be informed in the quantity of the independent CQI information of being fed back on the current sub-frame of uplink clearly, then can divide into groups to a plurality of ACK/NACK responses, a plurality of ACK/NACK responses are divided into a plurality of ACK/NACK response groups that equate with the number of CQI information according to the quantity of this independent CQI information.The number of the ACK/NACK response group after knowing grouping, promptly know after the group number that to divide, can specifically a plurality of ACK/NACK be responded and carry out concrete grouping according to default rule, the default rule of indication can be for according to actual conditions herein, as current channel condition etc. and the concrete rule of setting not is well-determined rule.Perhaps, the base station can be notified the concrete group result of the pairing ACK/NACK response of the various group numbers that may divide of terminal equipment by proprietary high-level signaling, carries out the grouping of corresponding ACK/NACK response again according to the number of the ACK/NACK response group of setting.
Particularly, when terminal equipment has only the ACK/NACK responsive feedback and when not having simultaneously CQI feedback information, also a plurality of ACK/NACK responses can be divided into groups, each ACK/NACK response group after the grouping generates the ACK/NACK information to be transmitted of 1 bit or 2 bits, and the ACK/NACK information to be transmitted that will generate is then transmitted on the ack channel of correspondence that is its distribution.Present embodiment terminal equipment have simultaneously the ACK/NACK response and during the CQI feedback information, a plurality of ACK/NACK response grouping situation of a plurality of ACK/NACK responses when having only the ACK/NACK feedback information is divided into groups, can so that no matter whether CQI message transmission is simultaneously arranged, the grouping situation of a plurality of ACK/NACK responses is identical, can simplify the design in some aspects of LTE-A system like this, for example descending allocation index (DownlinkAssignment Index; Hereinafter to be referred as: DAI).
Particularly, when the base station comes to a plurality of ACK/NACK according to the number of transmitting antenna that response is divided into groups, the number of the ACK/NACK response group of dividing can be no more than the number of transmitting antenna.Because in the LTE-A system, terminal equipment can dispose 1,2 or 4 transmit antennas, when being many transmit antennas of terminal equipment configuration, ACK/NACK information can be transmitted on ack channel that uses distribution on the different transmitting antennas respectively and CQI channel with CQI information.Think that terminal equipment configuration 2 transmit antennas are that example describes, terminal equipment can transmit a ACK/NACK information to be transmitted and a CQI information simultaneously, but may comprise many parts of ACK/NACK information to be transmitted and CQI information a up moment, if on the same transmit antenna, use a plurality of Channel Transmission ascending control informations simultaneously, then can cause cube tolerance (the Cubic Metric of terminal equipment; Hereinafter to be referred as: CM) significantly increase, and the channel transmitted number is many more simultaneously, and the increase of CM is serious more, and CM is the key factor that LTE system and LTE-A system are considered when design, the increase of CM can reduce the efficient of terminal equipment transmitting terminal power amplifier, and then reduces the coverage of system; If many parts of ACK/NACK information to be transmitted and CQI information are transmitted on different transmit antennas respectively, can keep lower CM, but the extensibility of system are reduced obviously.And the method that provides by present embodiment, a plurality of ACK/NACK responses are divided into groups, make the number of the ACK/NACK response group after dividing into groups be no more than the number of transmitting antenna, make different ACK/NACK response groups on different transmitting antennas, to transmit, can when keeping low CM, also can not reduce the extensibility of system.
Particularly, when the base station responds when dividing into groups a plurality of ACK/NACK according to the member carrier at the physical layer descending control signaling transmission place of the descending sub frame transfer of data corresponding with a plurality of ACK/NACK response, for the descending sub frame of transmission physical layer descending control signaling on identical member carrier, the ACK/NACK response corresponding with the data of transmitting on these descending sub frames can be divided into a group.For example shown in Figure 4, when the physical layer descending control signaling of terminal equipment can be transmitted on 4 member carriers of configuration, and ACK/NACK responds in the time of can being divided into two groups, the ACK/NACK response that the ACK/NACK response be divided into a group, the transmission physical layer descending is controlled the descending sub frame transfer of data of signaling on member carrier 2 and member carrier 3 in the descending sub frame transfer of data of transmission physical layer descending control signaling on member carrier 0 and the member carrier 1 can be divided into another group.Therefore, terminal equipment just can divide into groups the ACK/NACK response automatically according to the member carrier at the physical layer descending control signaling place of transfer of data.
It is to be noted, when response is divided into groups to a plurality of ACK/NACK, can also be simultaneously the physical layer descending of number, the descending sub frame transfer of data corresponding of grouping situation, transmitting antenna of a plurality of ACK/NACK responses during according to a terminal equipment feeding back ACK/NACK response with a plurality of ACK/NACK responses control signaling and transmit the member carrier at place and come two or three to divide into groups a plurality of ACK/NACK respond in these three factors of dividing into groups.For example, when simultaneously the grouping situation of a plurality of ACK/NACK responses comes a plurality of ACK/NACK responses are divided into groups according to the number of transmitting antenna and when having only the ACK/NACK responsive feedback in the base station, specifically can adopt following steps to carry out the grouping of ACK/NACK response: at first, the number of the physical layer ascending control channel that terminal equipment can transmit is simultaneously determined according to factors such as the number of transmitting antenna and channel quality status in the base station; Secondly, the number of the physical layer ascending control channel that the terminal equipment that the base station basis is determined can transmit simultaneously, a plurality of ACK/NACK are responded the identical group of number that is divided into the physical layer ascending control channel that can transmit simultaneously with terminal equipment, and notify terminal equipment grouping information.In addition, terminal equipment is having only the ACK/NACK feedback information and ACK/NACK information is arranged simultaneously and can a plurality of ACK/NACK responses divided into groups according to the above-mentioned grouping information of base station notice during the CQI feedback information.Perhaps, for example, the physical layer descending control signaling of the descending sub frame transfer of data of the grouping situation of a plurality of ACK/NACK responses and a plurality of ACK/NACK response correspondence was transmitted the member carrier at place when the base station responded according to a terminal equipment feeding back ACK/NACK simultaneously, carrying out a plurality of ACK/NACK responses divides into groups, specifically can adopt following steps, at first, the base station is according to the member carrier at the physical layer descending control signaling transmission place of the descending sub frame transfer of data corresponding with a plurality of ACK/NACK responses, carry out a plurality of ACK/NACK responses and divide into groups, and notify terminal equipment grouping information; Secondly, terminal equipment can respond a plurality of ACK/NACK according to the above-mentioned grouping information that the base station is notified and divide into groups when having only the ACK/NACK feedback information and ACK/NACK information is arranged simultaneously with the CQI feedback information.Perhaps, for example, when the base station is simultaneously come a plurality of ACK/NACK respond packet according to top three factors, specifically can adopt following steps to carry out the grouping of ACK/NACK response: at first, the number of the physical layer ascending control channel that terminal equipment can transmit is simultaneously determined according to factors such as the number of transmitting antenna and channel quality status in the base station; Secondly, the number of the physical layer ascending control channel that the terminal equipment that the base station basis is determined can transmit simultaneously, and the member carrier at the physical layer descending control signaling transmission place of the descending sub frame transfer of data corresponding with a plurality of ACK/NACK responses, a plurality of ACK/NACK are responded the identical group of number that is divided into the physical layer ascending control channel that can transmit simultaneously with terminal equipment, and notify terminal equipment grouping information; At last, terminal equipment is having only the ACK/NACK feedback information and ACK/NACK information is arranged simultaneously and can a plurality of ACK/NACK responses divided into groups according to the above-mentioned grouping information of base station notice during the CQI feedback information.
Step 302, terminal equipment divides into groups to a plurality of responses according to grouping information, generates a plurality of response groups.
Terminal equipment is after the grouping information that gets access to the base station transmission, and terminal equipment generates a plurality of ACK/NACK response groups according to the concrete grouping process of carrying out a plurality of ACK/NACK responses of this grouping information.Terminal equipment obtains a plurality of ACK/NACK response groups after a plurality of ACK/NACK responses are divided into groups, can comprise one or more ACK/NACK responses in the ACK/NACK response group, and group result is generated corresponding grouping information.When this grouping information is specially group result, in grouping information, can comprise the number of grouping back ACK/NACK response group, and the relevant informations such as ACK/NACK response that maximum possible comprises in each ACK/NACK response group.This grouping information can also specifically be indicated rule of classification, for example when the member carrier that transmits the place according to the physical layer descending control signaling of the descending sub frame transfer of data corresponding with a plurality of ACK/NACK responses divides into groups to a plurality of ACK/NACK responses, particularly, indication can be divided into one group automatically in the ACK/NACK of the descending sub frame transfer of data of which member carrier physical layer for transmission descending control signaling response.
It is multiplexing that the response message to be transmitted that step 303, terminal equipment generate at least one response group and CQI information are carried out, and the information after multiplexing is arrived the base station by at least one CQI Channel Transmission.
In the present embodiment, after response was divided into groups to a plurality of ACK/NACK by the base station, each ACK/NACK response group generated ACK/NACK information to be transmitted individually.If the ACK/NACK information to be transmitted that ACK/NACK response group generates will with the CQI information multiplexing after in the CQI channel, can generate 2 bits ACK/NACK information to be transmitted according to the mode that the LTE TDD system shown in the table 1 adopts; The ACK/NACK number of responses that comprises in group more for example to LTE-A FDD system, can directly respond corresponding ACK/NACK information as the ACK/NACK information to be transmitted that generates with ACK/NACK.For example in the LTE-A FDD system, suppose the ACK/NACK response is divided into 2 groups, for the terminal equipment that has disposed 4 downlink member carriers, ACK/NACK response that can per 2 downlink member carriers is one group, each ACK/NACK responds corresponding 1 bit ACK/nack message (when corresponding downlink data transmission adopts many codeword transmission, ACK that will be corresponding with each code word or NACK obtain 1 bit ACK/nack message by the logical AND operation, so-called logical AND operation obtains ACK when being meant that and if only and if all being ACK, otherwise obtain NACK), every group generates 2 bits ACK/NACK information to be transmitted; For the terminal equipment that has disposed 2 downlink member carriers, ACK/NACK response that can per 1 downlink member carrier is one group, directly this ACK/NACK response group is transmitted as the ACK/NACK information to be transmitted that generates, wherein, when the downlink data transmission is the single codeword transformat, each ACK/NACK response corresponds to the ACK/NACK information to be transmitted of 1 bit, when the downlink data transmission is many codeword transmission form, and when LTE and LTE-A system only supported 2 codeword transmission, each ACK/NACK response corresponded to the ACK/NACK information to be transmitted of 2 bits.

In above-mentioned table 1, with an ACK/NACK information to be transmitted of a plurality of ACK/NACK response becoming 2 bits, wherein, the quantity of ACK in a plurality of ACK/NACK responses is shown in first tabulation, secondary series is represented the ACK/NACK information to be transmitted [b (0), b (1)] of 2 bits.Wherein, have a NACK at least or detect in " 0 or do not have " a plurality of ACK/NACK responses of expression in first row second row and lose at least one descending distribution, as long as an ACK/NACK response is promptly arranged in a plurality of ACK/NACK response is lost for NACK or when having detected a downlink data transmission, then the number tag of ACK in a plurality of ACK/NACK response is " 0 or do not have ", show the downlink data transmission failure, the corresponding downstream data all need be retransmitted, at this moment, a plurality of ACK/NACK response 2 bits ACK/NACK information to be transmitted of shining upon generation accordingly by the mapping relations of table 1 is 00.Numerical value i in the first row remaining row represents that total i ACK/NACK responds (0≤i≤9, and i is a positive integer), and its whole values are ACK, and does not detect and lose descending distribution.Wherein, an ACK/NACK response is meant the ACK/NACK information that a descending sub frame transfer of data is fed back.As can be seen from Table 1, when the ACK/NACK information to be transmitted of 2 bits that generate through mapping is 00, show that this has the descending sub frame data transmission fails, the base station need retransmit the descending sub frame data of all scheduling, if and the number of ACK/NACK response is many more, the ACK/NACK information to be transmitted that then obtains 2 bits is that 00 probability is also big more.What present embodiment promptly proposed at this problem divides into groups to a plurality of ACK/NACK responses, and then carry out multiplexing and transmission, rather than all ACK/NACK response done as a wholely to carry out multiplexing and transmission, the ACK/NACK information to be transmitted that greatly reduces 2 bits of each ACK/NACK response group generation of grouping back like this is 00 probability, and then can reduce unnecessary information re-transmission.
Terminal equipment can be according to the ACK/NACK response group number of dividing and the CQI channel number of independent CQI information or distribution, ACK/NACK information to be transmitted that at least one ACK/NACK response group is generated by default mapping ruler and CQI information are carried out multiplexing, and the information after multiplexing is transmitted at least one CQI channel.Below with reference to example several concrete information multiplexing process under the different situations is carried out concrete explanation and explanation.
In above-mentioned steps 301, can be respectively come a plurality of ACK/NACK responses are divided into groups in conjunction with different factors in the base station, and the magnitude relationship between the number of the ACK/NACK response group of dividing under every kind of situation and the number of independent CQI information is all inequality.Particularly, when divide into groups to a plurality of ACK/NACK responses according to the number of the independent CQI information of current sub-frame of uplink feedback in the base station, the number of the ACK/NACK response group of division equals the number of independent CQI information; The grouping situation of a plurality of ACK/NACK responses when the base station responds according to a terminal equipment feeding back ACK/NACK, and/or the number of transmitting antenna, and/or the member carrier at the physical layer descending control signaling transmission place of the descending sub frame transfer of data corresponding with a plurality of ACK/NACK response responds when dividing into groups a plurality of ACK/NACK, the number of the ACK/NACK response group of division may greater than, be equal to or less than the number of independent CQI information.Below will carry out specific description, wherein, suppose that the number of the ACK/NACK response group of dividing is N the situation of the magnitude relationship between the number of the number of above-mentioned several ACK/NACK response groups and independent CQI information Group, the number of the independent CQI information of current sub-frame of uplink feedback is N CQI, wherein, N GroupWith N CQIBe positive integer.
When the number of the ACK/NACK response group of dividing equals the number of independent CQI information, i.e. N Group=N CQIThe time, after response is divided into groups to a plurality of ACK/NACK, the ACK/NACK information to be transmitted that ACK/NACK response group is generated and independent CQI information are carried out multiplexing according to mapping mode one to one, and the uplink feedback information of multiplexing back generation is transmitted on the CQI channel that is distributed for independent CQI information respectively.In the present embodiment promptly, each ACK/NACK response group mapping can be generated 1 bit or 2 bits ACK/NACK information to be transmitted, specifically can ACK/NACK response group mapping be generated 2 bits ACK/NACK information to be transmitted according to the mapping relations shown in the table 1, the ACK/NACK information a plurality of to be transmitted that will generate then respectively with a corresponding independent CQI information multiplexing after in the CQI of corresponding distribution channel.Promptly organize the mapping one by one of independent CQI information by the ACK/NACK response, carry out each ACK/NACK response group and an independent CQI information multiplexing, and uplink feedback information that each multiplexing back is generated is in the CQI of correspondence channel, and this corresponding CQI channel can be the channel for the independent CQI information distribution that generates this uplink feedback information.For example, Fig. 5 is the multiplexing schematic diagram of the first information among the information processing method embodiment three under the multi-carrier mode of the present invention, as shown in Figure 5, i the CQI channel of distributing behind ACK/NACK information to be transmitted that i ACK/NACK response group can be generated and the individual independent CQI information multiplexing of i, wherein, 0≤i＜N Group
As the number of the ACK/NACK response group of dividing number, i.e. N greater than independent CQI information Group＞N CQIThe time, after response is divided into groups to a plurality of ACK/NACK, the ACK/NACK information to be transmitted that the first quantity ACK/NACK response group is generated is carried out multiplexingly with the first quantity independence CQI information respectively according to mapping mode one to one, and the uplink feedback information that multiplexing back is generated transmits on the CQI channel that is distributed for independent CQI information respectively; The ACK/NACK response of the second quantity ACK/NACK response group is transmitted on the ack channel that is distributed for ACK/NACK response group respectively.Wherein, first quantity is the number N of independent CQI information CQI, second quantity is the poor (N of the number of the number of ACK/NACK response group and independent CQI channel quality indication (CQI) information Group-N CQI).Promptly in all ACK/NACK response groups of dividing, select the first quantity ACK/NACK response group, organize the mapping one by one of independent CQI information by the first quantity ACK/NACK response, carry out multiplexing with the first quantity independence CQI information ACK/NACK information that the first quantity ACK/NACK response group of selecting generates respectively, then after selecting the first quantity ACK/NACK response group, obtain the remaining second quantity ACK/NACK response group, the ACK/NACK information that the remaining second quantity ACK/NACK response group generates is transmitted on the ack channel that is distributed for ACK/NACK response group respectively.When selecting the first quantity ACK/NACK response group, for the sake of simplicity, can stipulate always to select to be positioned at the top first quantity ACK/NACK response group or selection is positioned at the rearmost first quantity ACK/NACK response group.In the present embodiment, first quantity can be specially N CQI, second quantity can be specially N Group-N CQI, promptly can be with the N that divides CQIThe ACK/NACK information to be transmitted that individual ACK/NACK response group generates respectively with an independent CQI information multiplexing after at the CQI of corresponding distribution channel, remaining (N Group-N CQI) individual ACK/NACK response group then the processing mode when having only the ACK/NACK feedback information on the ack channel that distributes, transmit, be about to (N Group-N CQI) the ACK/NACK information to be transmitted that generates of individual ACK/NACK response group transmits on the ack channel that distributes.For example, Fig. 6 is the second information multiplexing schematic diagram among the information processing method embodiment three under the multi-carrier mode of the present invention, as shown in Figure 6, and with i (0≤i＜N CQI) behind the ACK/NACK information to be transmitted that generates of ACK/NACK response group and i the independent CQI information multiplexing in i the CQI channel of distributing, simultaneously with the individual (N of j CQI≤ j＜N Group) ACK/NACK response group then the processing mode when having only the ACK/NACK feedback information on the ack channel that distributes, transmit.
Perhaps, as the number of the ACK/NACK response group of dividing number, i.e. N greater than independent CQI information Group＞N CQIAnd when equaling the number of ACK/NACK response group for the number of the CQI channel of independent CQI information distribution, after response is divided into groups to a plurality of ACK/NACK, carry out ACK/NACK information to be transmitted and CQI information that ACK/NACK response group generates multiplexing, and the uplink feedback information that multiplexing back is generated with for transmitting according to mapping mode one to one on the CQI channel, this independent CQI information is pre-configured on the CQI channel.Organize the mapping one by one of CQI channel by the ACK/NACK response, the ACK/NACK information to be transmitted that each ACK/NACK response group generates is carried out the transmission of multiplexing back with the independent CQI information of configuration on the CQI of correspondence channel.In the present embodiment, the base station is the number of the number of the CQI channel that distributes of the terminal equipment ACK/NACK response group that equals to divide by the proprietary signaling of high level, an independent CQI information can take a plurality of CQI channels simultaneously when having only the CQI message transmission, transmit by for example transmit diversity mode, behind ACK/NACK information to be transmitted that each ACK/NACK response group can be generated when ACK/NACK information and CQI message transmission are arranged at the same time and the CQI information multiplexing in corresponding CQI channel.For example, Fig. 7 is the 3rd information multiplexing schematic diagram among the information processing method embodiment three under the multi-carrier mode of the present invention, and as shown in Figure 7, the base station is that terminal equipment distributes N GroupIndividual CQI channel, wherein, the 0th～N CQI-2 independent CQI information are configured in the 0th～N of distribution respectively CQI-2 CQI Channel Transmission, N CQI-1 N that independent CQI information configuration is being distributed CQI-1～N Group-1 CQI Channel Transmission.The ACK/NACK information to be transmitted that the response of i ACK/NACK group can be generated is being transmitted on i the CQI channel that distributes with behind the CQI information multiplexing, wherein, and 0≤i＜N CQI
As the number of the ACK/NACK response group of dividing number, i.e. N less than independent CQI information Group＜N CQIThe time, after response is divided into groups to a plurality of ACK/NACK, it is multiplexing that the ACK/NACK information to be transmitted that each ACK/NACK response group is generated and an independent CQI information are carried out, and be to transmit on the CQI channel of independent CQI information distribution with the uplink feedback information that multiplexing back generates; The independent CQI information of the ACK/NACK information multiplexing to be transmitted that do not generate with ACK/NACK response group is being transmitted on the CQI channel of independent CQI information distribution.In independent CQI information, select N GroupIndividual independent CQI information is organized the N that selects by the ACK/NACK response GroupThe mapping one by one of individual independent CQI information, each ACK/NACK response group and different independent CQI information are carried out multiplexing, and with the information after multiplexing for transmitting on the CQI channel of independent CQI information distribution; To select N GroupRemaining N after the individual independent CQI information CQI-N GroupIndividual independent CQI information is being transmitted alone on the CQI channel of independent CQI information distribution.Select N GroupDuring individual independent CQI information, for the sake of simplicity, can stipulate always to select foremost N GroupIndividual or N backmost GroupIndividual independent CQI information.In the present embodiment, in the CQI of corresponding distribution channel, remaining independent CQI information is separately in the CQI channel of distribution behind the ACK/NACK information to be transmitted that each ACK/NACK response group can be generated and the independent CQI information multiplexing.For example, Fig. 8 is the 4th information multiplexing schematic diagram among the information processing method embodiment three under the multi-carrier mode of the present invention, as shown in Figure 8, and with i group (0≤i＜N Group) behind the ACK/NACK information to be transmitted that generates of ACK/NACK response and i the independent CQI information multiplexing in i the CQI channel of distributing, simultaneously with the individual (N of j Group≤ j＜N CQI-1) the independent CQI information CQI channel of distributing alone.

Described response message to be transmitted that at least one described response group is generated and independent channel quality indication (CQI) information carry out multiplexing, and the uplink feedback information of multiplexing generation is transferred to the base station by at least one channel quality indicating channel comprises:
Particularly, above-mentioned steps 303 can comprise: according to the number of response group and the independent CQ I information of current up moment feedback, it is multiplexing that the response message to be transmitted that at least one response group is generated and independent CQI information are carried out, and the uplink feedback information of multiplexing generation is arrived the base station by at least one CQI Channel Transmission.To a terminal equipment, different independent CQI information can be configured in the different up moment and feed back, and the independent CQI information number of feeding back in different up moment configurations also can be different simultaneously.Particularly, independent CQI information number is to be configured in the independent CQI information number that the current up moment feeds back.Terminal equipment is according to the ACK/NACK response group number and the independent CQI information number of dividing, undertaken ACK/NACK information to be transmitted and CQI information that at least one ACK/NACK response group generates multiplexing by default mapping ruler, and the information after multiplexing transmitted at least one CQI channel be meant: according to the ACK/NACK response group number of dividing be configured in the magnitude relationship of the independent CQI information number that the current up moment feeds back, select previously described a kind of concrete multiplex mode to carry out multiplexing.
Further, in the present embodiment, transmitting antenna can comprise first transmitting antenna and second transmitting antenna, wherein the maximum transmission power of first transmitting antenna is greater than the maximum transmission power of second transmitting antenna, first transmitting antenna is used for ACK/NACK information to be transmitted that transferring ACK/NACK response group generates and the shared CQI channel of information behind the independent CQI information multiplexing, and second transmitting antenna is used for the CQI channel that ack channel that ACK/NACK information to be transmitted that transferring ACK/NACK response group generates takies separately or independent CQI information take separately.Ack channel and CQI channel all belong to ascending control channel.By the content of foregoing description as can be known, when the number of the ACK/NACK response group of dividing is not equal to independent CQI information number, ACK/NACK information and CQI information can only be transmitted after multiplexing on the part ascending control channel, only transmit CQI information or ACK/NACK information on all the other ascending control channels.If different transmitting antennas has different maximum transmission power, for example terminal equipment has two transmit antennas and maximum transmission power to be respectively 23dBm and 20dBm, be that first transmitting antenna in the present embodiment can be the transmitting antenna of 23dBm corresponding to transmitting power, second transmitting antenna can be the transmitting antenna of 20dBm corresponding to transmitting power.First transmitting antenna with higher maximum transmission power can be used to transmit multiplexing the ascending control channel of ACK/NACK information and CQI information, second transmitting antenna that will have low maximum transmission power is used to transmit the ascending control channel that has only ACK/NACK information or CQI information.
In the present embodiment, ACK/NACK information to be transmitted and the CQI information concrete multiplex mode on the CQI channel can adopt the information multiplexing mode of LTE system, promptly under short Cyclic Prefix subframe structure, ACK/NACK information to be transmitted is placed on second pilot tone OFDM symbol transmission of each time slot of CQI channel, under the long loop prefix subframe structure, with behind 1 bit or 2 bit ACK/nack message and the CQI information combined coding in the CQI channel, information multiplexing mode in the following embodiments also can adopt above-mentioned similar information multiplexing mode, follow-up repeating no more.
Further, in the present embodiment, main downlink member carrier of configuration can also be selected for terminal equipment in the base station in the downlink member carrier of configuration.The member carrier of terminal equipment system information, the new configuration of activation or the member carrier that deexcitation has been disposed may be notified by main downlink member carrier in the base station.For the downlink data in main downlink member carrier transmission, its corresponding ACK/NACK response transmission requires performance more reliable.Particularly, if the number of the ACK/NACK response group of dividing is greater than the number of independent CQI information, and have only behind ACK/NACK information to be transmitted that part group ACK/NACK response generates and the independent CQI information multiplexing in the CQI of corresponding distribution channel, information multiplexing mode as shown in Figure 6, ACK/NACK response that preferably will be corresponding with the downlink data transmission of main downlink member carrier divides in the second quantity ACK/NACK response group, promptly partly organize the ACK/NACK response and when grouping, do not comprise the ACK/NACK response corresponding, can provide more reliable performance for the ACK/NACK response transmission corresponding like this with the downlink data transmission of main downlink member carrier with the downlink data transmission of main downlink member carrier.
Further, in the present embodiment, response can also comprise the dispatch request indication information, and promptly except ACK/NACK information and CQI information, the ascending control information in the present embodiment can also comprise dispatch request indication (Scheduling Request Indicator; Hereinafter to be referred as: SRI) information.When having only the SRI message transmission, the SRI channel that SRI information can distributed.The value of SRI information includes dispatch request (Positive SR) and does not have dispatch request (Negative SR) two states, promptly has/do not have dispatch request.Because SRI channel and ACK/NACK channel have essentially identical channel architecture, and on a channel, all can only pass the information of 1 bit or 2 bits, then in the present embodiment, SRI information also can be used as an ACK/NACK and responds and handle, and wherein Positive SR and Negative SR can be mapped as ACK and NACK respectively.When terminal equipment need be when the base station be fed back SRI information, ACK/NACK information and CQI information simultaneously, a SRI information can be handled as an ACK/NACK response, promptly in a plurality of ACK/NACK responses of dividing into groups, can comprise SRI information, with SRI information and a plurality of ACK/NACK response grouping together, the ACK/NACK information to be transmitted of at least one the ACK/NACK response group after the grouping is being transmitted on the CQI of at least one distribution channel with behind the CQI information multiplexing.Particularly, if the number of the ACK/NACK response group of dividing is greater than the number of independent CQI information, and have only behind ACK/NACK information to be transmitted that part A CK/NACK response group generates and the independent CQI information multiplexing in the CQI of corresponding distribution channel, information multiplexing mode as shown in Figure 6, preferably SRI information is divided in the second quantity ACK/NACK response group, be that part A CK/NACK response does not comprise when grouping by the SRI information of handling as the ACK/NACK response, can improve like this system to information processing efficient, improve the throughput of system.
