In the embodiment of the present invention, terminal obtains CSI request instructions field aperiodic；If aperiodic CSI request Instructions field indicates that the terminal needs to carry out CSI aperiodic to report, and the terminal is according to CSI aperiodic The instruction state of request instructions field, from the descending sub frame correspondence for receiving the CSI request aperiodic instructions field CSI aperiodic report set or carry the schedule information of the CSI request aperiodic instructions field and adjusted During corresponding CSI aperiodic of sub-frame of uplink of degree reports set, determining needs to carry out CSI aperiodic to report CSI aperiodic report set；The terminal transmission is described to be needed to carry out the aperiodic that aperiodic, CSI was reported CSI reports corresponding CSI aperiodic of set, so as to by configuring different descending sub frames corresponding aperiodics CSI reports set, or corresponding CSI aperiodic of different sub-frame of uplink to report set, realizes and passes through Less CSI triggerings aperiodic bit, indicates that different CSI aperiodic under more polymerization carrier case are reported The A-CSI of set is reported.

Optionally, CSI aperiodic reports set to be specially：CSI processes and CSI sub-frame sets are to shape Into set, carrier set, one or more in CSI process collections of combination.

Illustrate, CSI processes and CSI sub-frame sets the set for being formed can be expressed as CSI processes, CSI sub-frame sets } to set, wherein CSI sub-frame sets are the subframes for carrying out CSI measurements, tool Hold in vivo and repeat no more.For example, { CSI processes, CSI sub-frame sets } to set in the element that includes be： { CSI processes 1, CSI sub-frame sets 1 } to, { CSI processes 2, CSI sub-frame sets 2 }, { CSI processes 3, CSI sub-frame sets 3 } etc..

It should be noted that carrier set is it can be appreciated that service cell set, each Serving cell is included At least one up-link carrier and/or at least one descending carrier, the uplink in Serving cell are included by which At least one up-link carrier realize, the downlink transfer in Serving cell by its include it is at least one descending Carrier wave is realized, as A-CSI is obtained based on the associated reference signal measurement on descending carrier, therefore It is the A-CSI of descending carrier that A-CSI is corresponding.

Optionally, the CSI request aperiodic instructions field is carried and is permitted in DCI or accidental access response (grant) in.

In the embodiment of the present invention, for the terminal of multiple carrier waves that have been polymerized, give the correct time on CSI aperiodic in triggering, Including following two optional implementations：

Mode one, the carrying out triggered CSI aperiodic that CSI is reported aperiodic report set with comprising non-week The descending sub frame that the DCI of phase CSI request instructions field or accidental access response license (grant) transmission are located Correlation, that is, be configured with corresponding CSI aperiodic of different descending sub frames and report set, and terminal can be according to reception To the descending sub frame of CSI request instructions field aperiodic, the non-week for needing to carry out that aperiodic, CSI was reported is determined Phase CSI reports set.

Under which, CSI report sets aperiodic corresponding to the descending sub frame are combined into high-level signaling and match somebody with somebody in advance CSI aperiodic for putting reports set.

Under which, aperiodic described in the descending sub frame correspondence at least one, CSI reported set, and different Descending sub frame corresponding to CSI aperiodic report Set-dissection identical or entirely different.

Under which, the instruction state of the CSI request aperiodic instructions field is corresponding with the descending sub frame Aperiodic, CSI reported the corresponding relation of set to make an appointment or being pre-configured with by high-level signaling.

Illustrate, for arbitrary descending sub frame, the value of the CSI request aperiodic instructions field is When " 000 ", its instruction state is to report without CSI aperiodic；The CSI request aperiodic instructions field Be worth for " 001 " when, its instruction state is that CSI aperiodic of the scheduled carrier wave of triggering is reported；The non-week When the value of phase CSI request instructions field is " 010 ", " 011 ", " 100 ", " 101 ", " 110 " and " 111 ", Its instruction state different CSI aperiodic that respectively triggering high-level signaling is pre-configured with report the aperiodic of set CSI is reported.

It should be noted that if there is multiple descending sub frames, corresponding CSI aperiodic of each descending sub frame Report set can with entirely different, for example, it is assumed that define 12 aperiodic CSI report set, it is descending Correspondence triggering CSI aperiodic of subframe 1 reports CSI aperiodic of set 1～6 to report, 2 correspondence of descending sub frame Triggering CSI aperiodic reports CSI aperiodic of set 7～12 to report；Or corresponding to different descending sub frames CSI aperiodic report Set-dissection identical, for example, it is assumed that define 8 aperiodic CSI report set, Correspondence triggering CSI aperiodic of descending sub frame 1 reports CSI aperiodic of set 1～6 to report, descending sub frame 2 Correspondence triggering CSI aperiodic reports set 1～4 and CSI aperiodic to report CSI aperiodic of set 7～8 Report.

If there is N number of descending sub frame in a radio frames, the non-week independently defined by N1 descending sub frame Phase CSI reports set set can be reported to indicate respectively all CSI aperiodic with realization, then remaining CSI aperiodic corresponding to N-N1 descending sub frame report set can with N1 descending sub frame in it is any CSI aperiodic corresponding to one subframe reports set.For example, available descending sub frame in a radio frames There are 10, then the corresponding relation of same descending sub frame 1 can be all defined to descending sub frame 1,3,5,7,9, Corresponding to triggering CSI aperiodic reports CSI aperiodic of set 1～6 to report, to descending sub frame 2,4,6, 8th, 10 the corresponding relation of same descending sub frame 2 is all defined, that is, corresponds to triggering CSI aperiodic and report set 7～12 CSI aperiodic report, now, if base station want to trigger CSI aperiodic report it is any in set 1～6 One aperiodic, CSI reported give the correct time on CSI the aperiodic of set, can produce corresponding CSI aperiodic Send in request instructions field, and any one descending sub frame in descending sub frame 1,3,5,7,9 and carry Aperiodic CSI request instructions field DCI or accidental access response grant.Accordingly, terminal exists CSI request aperiodic detected in any one descending sub frame in descending sub frame 1,3,5,7,9 refers to Show domain, it is determined that CSI aperiodic for being triggered reports set.

Mode two, the carrying out triggered CSI aperiodic that CSI is reported aperiodic report set with to include this non- Sub-frame of uplink scheduled in the DCI or accidental access response grant of cycle CSI request instructions field is related, i.e., It is configured with corresponding CSI aperiodic of different sub-frame of uplink and reports set, terminal can be according to receives aperiodic Sub-frame of uplink scheduled in the descending sub frame of CSI request instructions field, determining needs to carry out on CSI aperiodic CSI aperiodic of report reports set.

Under which, CSI report sets aperiodic corresponding to the sub-frame of uplink are combined into high-level signaling and match somebody with somebody in advance CSI aperiodic for putting reports set.

Under which, aperiodic described in the sub-frame of uplink correspondence at least one, CSI reported set, and different Sub-frame of uplink corresponding to CSI aperiodic report Set-dissection identical or entirely different.

Under which, the instruction state of the CSI request aperiodic instructions field is corresponding with the sub-frame of uplink Aperiodic, CSI reported the corresponding relation of set to make an appointment or being pre-configured with by high-level signaling.

Illustrate, for arbitrary sub-frame of uplink, the value of the CSI request aperiodic instructions field is When " 000 ", its instruction state is to report without CSI aperiodic；The CSI request aperiodic instructions field Be worth for " 001 " when, its instruction state is that CSI aperiodic of the scheduled carrier wave of triggering is reported；The non-week When the value of phase CSI request instructions field is " 010 ", " 011 ", " 100 ", " 101 ", " 110 " and " 111 ", Its instruction state different CSI aperiodic that respectively triggering high-level signaling is pre-configured with report the aperiodic of set CSI is reported.

Under which, optionally, high-level signaling is pre-configured with the descending sub frame correspondence for dispatching uplink subframe CSI aperiodic report set.That is, the sub-frame of uplink is configured with corresponding CSI aperiodic Set is reported, the descending sub frame for dispatching the sub-frame of uplink also provided corresponding CSI aperiodic and report Set.

In the optional mode, terminal needs to know using which kind of corresponding relation.Implement including：Pass through High-level signaling notifies that terminal determines to be needed to carry out adopting when CSI aperiodic that aperiodic, CSI was reported reports set Subframe report the corresponding relation of set with CSI aperiodic, or terminal of making an appointment determine need to carry out it is non- CSI aperiodic that cycle CSI is reported reports the subframe adopted during set to report the right of set with CSI aperiodic Should be related to.

The corresponding relation includes that the descending sub frame for dispatching the sub-frame of uplink reports the right of set with CSI aperiodic Should be related to (corresponding CSI aperiodic of descending sub frame for dispatching the sub-frame of uplink reports set), and The sub-frame of uplink reports the corresponding relation of set (even sub-frame of uplink corresponding non-week with CSI aperiodic Phase CSI reports set).
