Step 12, resource information shared by the data channel of the resource information that takies of described scheduling authorization order received and/or described scheduling authorization order instruction obtain CSI location label;

Particularly, the resource information that described scheduling authorization order takies and/or the resource information shared by data channel that described scheduling authorization order indicates can comprise the time that scheduling authorization order takies, frequency domain, space and code channel information, and/or the time that the data channel of described scheduling authorization order instruction takies, frequency domain, space and code channel information, specifically can comprise for lte-a system: the subframe label at scheduling authorization order place, the control channel element numerals that scheduling authorization order takies, community, scheduling authorization order place label, scheduling authorization order place carrier wave label, the community label at described data channel place, the carrier wave label at described data channel place, at least one in the parameter of the subframe label at the Physical Resource Block label that described data channel transmission takies and described data channel place, such as: the subframe label 5 that can only include scheduling authorization order place, or only include the Physical Resource Block label 1 that data channel transmission takies, also the combination of the subframe label 3 at scheduling authorization order place and the community label 2 at data channel place can be comprised, both are added and obtain 5.The combination of two kinds of parameters can be any one function being independent variable with described two kinds of parameters, the most simply combines and is such as added, subtracts each other, is multiplied or is divided by, and for convenience of description, hereinafter the combination of two kinds of parameters all adds up to example with two kinds of parameters and is described.When scheduling authorization order occupies multiple control channel unit, the label of first or last control channel unit can be chosen; Equally, when data channel transmission occupies multiple Physical Resource Block, also can choose the label of first or last Physical Resource Block.

In carrier aggregation, a subscriber equipment can access multiple member carrier simultaneously, and the carrier wave of the different center carrier frequences of the community in the normally identical or close geographical position of member carrier here has identical community label and different carrier wave labels.Coordinate in multiple spot transmitting-receiving, a subscriber equipment can access multiple community simultaneously, and community here normally has the community of the diverse geographic location of identical central carrier frequency, has different community labels and identical carrier wave label.Visible, no matter be the member carrier in carrier aggregation or the community of coordinating in multiple spot transmitting-receiving, minimum recognition unit is all the carrier wave of a certain center carrier frequence of community, a certain geographical position.For convenience of description, the member carrier in carrier aggregation and the community of coordinating in multiple spot transmitting-receiving are referred to as carrier wave below.

Step 13, by described data channel, the CSI of carrier wave corresponding to described CSI location label obtained is sent to described base station.

Particularly, data channel can be Physical Uplink Shared Channel PUSCH (Physical UplinkShared Channel) or Physical Downlink Shared Channel PDSCH (Physical DownlinkShared Channel), and the present embodiment is all the explanations carried out for PUSCH.

In said method, the resource information shared by data channel of the resource information that described scheduling authorization order can specifically take by step 12 and/or described scheduling authorization order instruction is as CSI location label, such as, the resource information shared by data channel of the resource information that scheduling authorization order takies and/or described scheduling authorization order instruction comprises: the combination of the subframe label 3 at scheduling authorization order place and the community label 2 at described data channel place, both are added and obtain 5, and so CSI location label is 5;

Result after the carrier number delivery that the resource information shared by data channel of the resource information that described scheduling authorization order can also specifically take by step 12 and/or described scheduling authorization order instruction accesses subscriber equipment self is as CSI location label, such as, the resource information shared by data channel of the resource information that scheduling authorization order takies and/or described scheduling authorization order instruction comprises: the combination of the subframe label 3 at scheduling authorization order place and the community label 2 at described data channel place, both are added and obtain 5, the carrier number of described subscriber equipment access is 3, result 2 then after delivery is CSI location label.

Based on the implementation method of above-mentioned two kinds of steps 12 specifically, the CSI of carrier wave equal with described CSI location label for carrier information specifically can be sent to described base station by described data channel by corresponding step 13, such as: the CSI location label of acquisition is 2, then the CSI of carrier wave 2 is sent to base station.Described carrier information can comprise community label and carrier wave label simultaneously, can also only comprise carrier wave label for carrier aggregation, can also only comprise community label for the transmitting-receiving of coordination multiple spot.

Before step 11, can also comprise step 10: receive the high-level signaling that base station sends, described high-level signaling comprises at least one of CSI feedback indication information aperiodic, and described aperiodic, CSI feedback indication information comprised at least one carrier information; Wherein, each aperiodic CSI feedback indication information corresponding one aperiodic CSI feedback indication numbers.Described high-level signaling specifically can representation case as follows:

Aperiodic CSI feedback indication numbers	Carrier information
		0	2，3

1	1
		2	0

When receiving above-mentioned high-level signaling, the resource information shared by data channel of the resource information that described scheduling authorization order can specifically take by step 12 and/or described scheduling authorization order instruction is as CSI location label, such as, the resource information shared by data channel of the resource information that scheduling authorization order takies and/or described scheduling authorization order instruction comprises: the combination of the subframe label 3 at scheduling authorization order place and the community label 2 at described data channel place, both are added and obtain 5, and so CSI location label is 5.

The resource information that described scheduling authorization order can also specifically take by step 12 and/or described scheduling authorization order instruction the resource information shared by data channel in described high-level signaling aperiodic CSI feedback indication information number delivery after result as CSI location label, described aperiodic, the number of CSI feedback indication information can be obtained by high-level signaling, such as, the resource information shared by data channel of the resource information that scheduling authorization order takies and/or described scheduling authorization order instruction comprises: the combination of the subframe label 3 at scheduling authorization order place and the community label 2 at described data channel place, both are added and obtain 5, if as in the example of step 10 aperiodic CSI feedback indication information number be 3, result 2 then after delivery is CSI location label.

Based on three kinds of implementation methods of step 12 during reception above-mentioned high-level signaling, step 13 specifically can obtain corresponding CSI feedback indication information aperiodic by described high-level signaling according to CSI feedback indication numbers aperiodic equal with described CSI location label, and by described data channel, the CSI of the carrier wave corresponding to the carrier information of the aperiodic of acquisition in CSI feedback indication information is sent to described base station; Such as, the CSI location label obtained is 2, in as corresponding in CSI feedback indication numbers 2 equal with CSI location label in the example of step 10 aperiodic aperiodic CSI feedback indication information, carrier information is 0, so by described data channel, the CSI of carrier wave 0 is sent to base station.

Based on three kinds of implementation methods of step 12 during reception above-mentioned high-level signaling, step 13 specifically can also obtain the carrier information equal with described CSI location label according to described high-level signaling, and obtain CSI feedback indication information aperiodic corresponding to described carrier information, then by described data channel, the CSI of carrier wave corresponding for the carrier information of the aperiodic of acquisition in CSI feedback indication information is sent to described base station; Such as, the CSI location label obtained is 2, CSI feedback indication information aperiodic as corresponding in the carrier information 2 in aperiodic equal to CSI location label CSI feedback indication information in the example of step 10 be aperiodic CSI feedback indication numbers 0 corresponding, so by described data channel, the CSI of carrier wave 2 and 3 is sent to base station.Now, step 12 one kind preferably implementation method can also be by the community label at the community label at the carrier wave label at scheduling authorization order place, scheduling authorization order place, the carrier wave label at described data channel place or described data channel place, as CSI location label.

In step 10, carry out carrier wave configuration CSI feedback aperiodic to subscriber equipment self access by high-level signaling.Described high-level signaling can be RRC (Radio Resource Control, the wireless heterogeneous networks) signaling that base station issues, and also can be MAC (Medium Access Control, the M AC) signaling that base station issues.In lte-a system, to a subscriber equipment, according to its hardware capabilities and data traffic requirement, base station notifies a carrier set by RRC signaling for it, there is shown the carrier wave that subscriber equipment likely accesses.Base station can also be activated by MAC signaling or carrier wave in deexcitation carrier set.When described high-level signaling be base station issue RRC signaling time, the carrier wave of self access described can be whole carrier waves in the carrier set of RRC signaling; When described high-level signaling is MAC signaling, the carrier wave of self access described can be whole carrier waves of current activation.When being carried out carrier wave configuration CSI feedback aperiodic to subscriber equipment self access by described high-level signaling, CSI feedback aperiodic can be all configured to all carrier waves of subscriber equipment self access, also can only to partial carrier wave configuration CSI feedback aperiodic of subscriber equipment self access.

In step 13, by described data channel, the CSI of carrier wave corresponding for the carrier information of the aperiodic of acquisition in CSI feedback indication information is sent to described base station.The carrier wave that carrier information in described aperiodic CSI feedback indication information is corresponding can be all carrier waves that carrier information in CSI feedback indication information aperiodic is corresponding.Consider in lte-a system, for the carrier wave being in deactivation status, subscriber equipment does not need to base station feedback CSI.Thus the carrier wave that the carrier information in CSI feedback indication information described aperiodic is corresponding also can be all carrier waves being in state of activation that carrier information in CSI feedback indication information aperiodic is corresponding.

If also comprise CSI Carrier selection information in the described scheduling authorization order received in step 11, so above-mentioned two kinds of steps 13 can also comprise: according to described CSI Carrier selection information, select at least one carrier information in CSI feedback indication information described aperiodic, the CSI of carrier wave corresponding for the carrier information of selection is sent to described base station by described data channel.In lte-a system, for the subscriber equipment accessing multiple carrier wave simultaneously, CIF (the Carrier IndicatorField of 3 bits may be comprised in its uplink scheduling authorization order, carrier wave instructions field) field, the PUSCH being used to indicate this uplink scheduling authorization command scheduling specifically at which up-link carrier sends.Usually, it is less that subscriber equipment accesses the up-link carrier number sending data simultaneously, and be such as no more than 2, CIF field can have some redundant bits or redundant state.Thus CIF field can be utilized to be used as up-link carrier and the instruction of CSI Carrier selection information at PUSCH place simultaneously.Such as, when the up-link carrier number accessed is 2, indicate the PUSCH of scheduling at which up-link carrier to send in 3 bit CIF fields with 1 bit, 2 remaining bits can as CSI Carrier selection information.If not carrier information is 0 and 1 in cycle CSI feedback indication information, and select carrier wave 0 with 2 bit CSI Carrier selection information instructions in the scheduling authorization order received, so this time only the CSI of carrier wave 0 is sent to base station.

As shown in Figure 2, illustrate with the carrier number of subscriber equipment self access as 3, the subframe label at scheduling authorization order place is 5, the Physical Resource Block label that described data channel transmission takies is 2, the community label at described data channel place is 1, and the community label at the Physical Resource Block label taken according to the subframe label at scheduling authorization order place, described data channel transmission and described data channel place, get with rear be example to the result after carrier number 3 delivery of subscriber equipment self access as CSI location label, said method is specifically described:

Step 21, receiving scheduling authorization command, the subframe label obtaining scheduling authorization order place is 5, and the Physical Resource Block label that described data channel transmission takies is 2, and the community label at described data channel place is 1.

Step 22, the community label 1 at the subframe label 5 at the described scheduling authorization order place obtained, Physical Resource Block label 2 that described data channel transmission takies and described data channel place is added after carrier number 3 delivery to subscriber equipment access, obtaining CSI location label is (5+2+1) mod3=2.

Step 23, by the data channel of community label 1, the CSI of the carrier wave 2 equal with CSI location label 2 is sent to base station.
