As shown in Figure 5, be the indicating means schematic diagram of multicarrier ascending control channel in the embodiment of the invention one, the method mainly may further comprise the steps:
Step 101: network side is determined terminal in professional transmission course, the descending carrier that actual needs takies.
In this step, can determine the descending carrier that the terminal actual needs takies according to pending type of service and traffic carrying capacity.
In the present embodiment, network side can be simultaneously for a plurality of terminals provide service, follow-up can describing as a terminal configuration ascending control channel as example take network side.
Step 102: network side is that the actual descending carrier that takies of terminal distributes corresponding ascending control channel.
For a terminal, network side is determined the quantity of ascending control channel according to the quantity of the actual descending carrier that takies of this terminal, and the quantity of ascending control channel is not less than the quantity of the actual descending carrier that takies of terminal.Network side is selected the ascending control channel with the quantity same number of the actual descending carrier that takies from a plurality of ascending control channels, and the ascending control channel of foundation selection and the corresponding relation of the actual descending carrier that takies, wherein: the ascending control channel that any two descending carriers distribute is different, and namely descending carrier is corresponding one by one with ascending control channel.

In this step, the corresponding relation of ascending control channel and descending carrier can be controlled by Radio Resource (Radio Resource Control, RRC) signaling sends to terminal, also can by other can the bearing downlink carrier wave sign and the high-level signaling of the sign of corresponding ascending control channel send to terminal.
By step 101 to step 103, network side has been finished the configuration to the ascending control channel of terminal, and follow-up when carrying out transfer of data, terminal can be according to the sign of the sign of the descending carrier that receives and corresponding ascending control channel, finish the ACK/NACK feedback, concrete feedback procedure is as follows:
Step 104: network side sends the continuous dispatching data by descending carrier to terminal.
Step 105: after terminal receives the continuous dispatching data by descending carrier, determine the sign of this descending carrier.
Step 106: terminal is determined the sign of the ascending control channel corresponding with the sign of this descending carrier according to the sign of described descending carrier.
Step 107: terminal is transferred to network side with the feedback information of the continuous dispatching data that the receive ascending control channel by the sign correspondence of the ascending control channel determined.
Scheme by the embodiment of the invention one, network side is before the continuous dispatching transfer of data begins, the ascending control channel that is used for the carrying feedback information for terminal configuration, and the corresponding relation of each ascending control channel and descending carrier sent to terminal, allow terminal in the process of carrying out transfer of data, find out for the ascending control channel that carries feedback information according to the corresponding relation of knowing in advance, finish the uplink feedback in the LTE-A system.
In the step 103 of the scheme of embodiment one, network side can send to corresponding terminal with ascending control channel with the corresponding relation of descending carrier by the mode of explicit or implicit expression, and the below describes respectively.
Send the implicit 1 of corresponding relation:
Consider by the RRC signalling time, the quantity of signaling unit is identical with descending carrier quantity in the system in the RRC signaling, has one to one relation between signaling unit in the RRC signaling and each descending carrier in the multicarrier system, therefore, network side can certain descending carrier is corresponding the sign of ascending control channel be placed in signaling unit corresponding to this descending carrier, do not distribute and to be set to zero or for empty, the RRC signaling that then will place the sign of ascending control channel sends to corresponding terminal in signaling unit corresponding to the descending carrier of ascending control channel.In the case, when the RRC signaling that end-on is received is identified, can know that the sign place descending carrier corresponding to signaling unit of ascending control channel is exactly the descending carrier of the sign correspondence of this ascending control channel.
For example: the descending carrier in the system has 5, and its numbering is respectively 1,2,3,4 and 5, and wherein, being numbered 1 and 3 descending carrier is the actual descending carrier that takies of terminal, and being numbered 2,4 and 5 descending carrier is the unappropriated descending carrier of terminal.Network side is 2 ascending control channels of terminal distribution, and the ascending control channel reference numeral that is designated n1PUCCH-AN1 is 1 descending carrier, and the ascending control channel reference numeral of sign n1PUCCH-AN3 is 3 descending carrier.
5 signaling units are arranged in the RRC signaling, and each signaling unit is corresponding one by one with a descending carrier.
Network side is placed on n1PUCCH-AN1 and is numbered in signaling unit corresponding to 1 descending carrier, and n1PUCCH-AN3 is placed on and is numbered in signaling unit corresponding to 3 descending carrier, is set to sky in all the other 3 signaling units.
Network side sends to corresponding terminal with the RRC signaling that sets, terminal recognition has gone out to place the signaling unit of the sign of ascending control channel, determine that corresponding descending carrier is respectively to be numbered 1 and 3 descending carrier, the ascending control channel reference numeral that then further can determine to be designated n1PUCCH-AN1 is 1 descending carrier, and the ascending control channel reference numeral that is designated n1PUCCH-AN3 is 3 descending carrier.
Send the implicit 2 of corresponding relation:
Network side is numbered the sign of ascending control channel according to the descending carrier of correspondence ascending order or descending, and the sign of the ascending control channel after will arranging is placed in the signaling unit of RRC signaling successively, because the quantity of signaling unit is identical with the descending carrier quantity that terminal takies in the RRC signaling, and signaling unit is corresponding one by one to the actual descending carrier that takies of terminal, therefore, after terminal receives the RRC signaling, corresponding relation according to signaling unit and descending carrier, descending carrier corresponding to each signaling unit in the RRC signaling of at first determining to receive, then again according to sign and the descending carrier corresponding to this signaling unit of the ascending control channel of placing in the signaling unit, determine the corresponding relation of ascending control channel and descending carrier.
For example: the descending carrier in the multicarrier system has 5, and its numbering is respectively 1,2,3,4 and 5, and wherein, being numbered 1 and 3 descending carrier is the actual descending carrier that takies of terminal, and being designated 2,4 and 5 descending carrier is the unappropriated descending carrier of terminal.Be numbered the n1PUCCH-AN1 that is designated of ascending control channel corresponding to 1 descending carrier, be numbered the n1PUCCH-AN3 that is designated of ascending control channel corresponding to 3 descending carrier.
2 signaling units are arranged in the RRC signaling, and the first signaling unit is corresponding one by one with the descending carrier that is numbered 1, and the second signaling unit is corresponding one by one with the descending carrier that is numbered 3.After terminal receives the RRC signaling, according to the n1PUCCH-AN3 that places in the n1PUCCH-AN1 that places in the first signaling unit and the second signaling unit, the ascending control channel reference numeral of determining to be designated n1PUCCH-AN1 is 1 descending carrier, and the ascending control channel reference numeral that is designated n1PUCCH-AN3 is 3 descending carrier.
Because above-mentioned dual mode all is to have utilized the next indirect notification terminal ascending control channel of corresponding relation of signaling unit and descending carrier and the corresponding relation of descending carrier, therefore, is a kind of implicit.
Send the explicit way of corresponding relation:
The numbering of the sign of definite each ascending control channel that distributes of network side and corresponding descending carrier, be placed in the signaling unit of RRC signaling after the numbering binding with the sign of the ascending control channel of correspondence and descending carrier, then the RRC signaling sent to corresponding terminal.Terminal directly just can be determined the corresponding relation of ascending control channel and descending carrier according to the numbering of the sign of the ascending control channel of binding in the signaling unit and descending carrier when identification RRC signaling.
Because network side directly sends to terminal with the numbering of the descending carrier of the sign of ascending control channel and binding in the manner, is a kind of explicit way therefore.
In embodiments of the present invention, the sign of ascending control channel can have multiple method to set up, below for wherein may two kinds of methods to set up:
First method:
With the ascending control channel serial number in each up-link carrier in the multicarrier system, the call number that is designated ascending control channel of ascending control channel.In the case, the call number of any two ascending control channels in the multicarrier system is different.
For example: 2 up channels are arranged in the multicarrier system, and numbering is respectively A and B.At the up-link carrier that is designated A be designated in the up-link carrier of B respectively that configuration pin is four ascending control channels of terminal configuration to two ascending control channels of same terminal.The call number that can be arranged on the ascending control channel in the up-link carrier that is designated A is 001 and 002, the call number of the ascending control channel in being designated the up-link carrier of B is 003 and 004, namely do not distinguish the up-link carrier that ascending control channel is positioned at, all ascending control channels are carried out serial number, at this moment, the call number of ascending control channel can represent this ascending control channel uniquely.
Second method:
To the ascending control channel independent numbering in each up-link carrier, the up-link carrier that is designated of ascending control channel is numbered and the ascending control channel call number respectively.In the case, take a up-link carrier as unit, the ascending control channel that will be positioned at same up-link carrier is united numbering respectively.When numbering is finished, the call number of two ascending control channels that different up-link carriers may occur being positioned at is identical, namely only can't uniquely represent an ascending control channel with the call number of ascending control channel, therefore, the carrier index of the up-link carrier at the call number that is designated this ascending control channel of ascending control channel and this ascending control channel place.
For example: at the up-link carrier that is designated A be designated in the up-link carrier of B respectively that configuration pin is four ascending control channels of terminal configuration to two ascending control channels of same terminal.The call number that can be arranged on the ascending control channel in the up-link carrier that is designated A is 001 and 002, the call number of the ascending control channel in being designated the up-link carrier of B is also for being 001 and 002, at this moment, call number can not ascending control channel of unique expression, therefore, the sign of ascending control channel comprises up-link carrier numbering A-001, A-002, B-001 and the B-002 at call number and place.
In the second approach, the carrier index of up-link carrier can be the call number of up-link carrier in carrier aggregation system, also can be the call number in the actual up-link carrier that takies of terminal.
Distinguishingly, if there is exclusive up main carrier in terminal, namely the corresponding feedback information of the data of user's downlink transfer always transfers to network side by some up-link carriers, and then the sign of ascending control channel can be call number.
The embodiment of the invention one also is not limited to the mode of other possible signs that ascending control channel is set, and can make network side and the unique identification ascending control channel of terminal as long as can determine the sign of the ascending control channel that arranges.
