As a preferred embodiment of the present invention, the dynamic signaling includes CSI request domain, and it is N that the CSI request domain, which includes bit number, and the N is the integer more than or equal to 1；

The dynamic signaling is used to indicate that the UE needs the CSI of feeding back channel state information CSI first service cell to measure and assumes that set is assumed in the CSI measurements of set or service cell set, including：

The dynamic signaling indicates that the CSI's based on CSI measurement hypothesis set of triggering first service cell reports or indicate that the upper ability for triggering the CSI gathered based on CSI measurement hypothesis of at least one second service cell of service cell set is blunt by the CSI request domain.

For example：When the CSI request domain indicates that the CSI measurements of triggering first service cell assume that the CSI of set upper ability is blunt.

In the present embodiment, the first service cell includes but is not limited to following any：Predefined serving cell, the serving cell configured by high-level signaling, the serving cell for sending dynamic signaling, the serving cell for receiving aperiodic CSI and the serving cell of dynamic signaling instruction.

It is following at least one that the CSI measurements assume that set includes but is not limited to：First CSI measurements are assumed, first CSI measurement 4 is blunt to be set to pre-defined CSI measurements H and not to have, or the first CSI measure 4 Jia be set to the CSI measurements that are configured by high-level signaling it is assumed that or the first CSI measurements be assumed to be that numbering is minimum or highest CSI measures H and do not had；Except the first CSI CSI measurements H measured in addition to H does not have do not have；All CSI measurements 4 are blunt to be set；The first CSI measurements H is with one or more except the first CSI measures the combination that the CSI measurements in addition to 4 Jia are set are assumed；And set is assumed in the CSI measurements of high-level signaling configuration.

In the present embodiment, the CSI measurements are assumed to be allocated to the UE by high-level signaling, and CSI is surveyed Amount assumes that including channel measurement assumes and interferometry hypothesis.Following first CSI are measured to the CSI assumed and are designated as CSI1, the CSI measurements in addition to the CSI1 assume that corresponding CSI is designated as CSI2 and CSI3.

Receive the bit in the CSI request domain that base station is configured by the first high-level signaling（Bit) number N.If for example, CSI request domain is lbit, as shown in Table 2：

If CSI request domain is 2bit, as shown in Table 3:

If CSI request domain is 3bit, as shown in Table 4:

Reporting for the CSI gathered is assumed in the CSI measurements that the CSI request domain that reception base station is configured by the second high-level signaling is used to trigger the first service cell；Or reporting for the CSI gathered is assumed in the CSI measurements that reception base station is used to trigger the first service cell by the CSI request domain transmitted CSI request domain or configured by least one in following manner：

Send the CSI of carrying non-periodic feedback physical layer Uplink Shared Channel PUSCH time-domain resource numbering；

Frequency domain resource is numbered；With

Serving cell is numbered.

Particularly, the rule that the UE is configured according to predefined rule or the base station that receives by high-level signaling, and it is following at least one：The time-domain resource numbering and frequency domain resource are numbered, and service cell number, judge whether reporting for the CSI gathered is assumed in the CSI measurements for triggering first service cell in CSI request domain.

If at least one in following：The time-domain resource numbering and frequency domain resource numbering, with service cell number, meet the rule that the predefined rule or base station are configured by high-level signaling, then reporting for the CSI of set is assumed in the CSI measurements for triggering the first service cell by the CSI request domain；Otherwise the CSI request domain is not used in reporting for the CSI for the CSI measurement hypothesis set for triggering the first service cell.For example assume transmission CSI request domain it is following at least one：The time-domain resource numbering and frequency domain resource numbering, with service cell number, for 1,1 be even number when, represent that reporting for the CSI of set is assumed in CSI measurement of the CSI request domain for triggering first service cell, 1 when being odd number, represents that CSI request domain is not used in the CSI measurements of triggering first service cell and assumes that the CSI of set is reported；Or predefined set L, if k L, represent that set is assumed in CSI measurement of the CSI request domain for triggering first service cell CSI's reports, if L, represents that CSI request domain is not used in reporting for the CSI of the CSI measurement hypothesis set of triggering first service cell.

If reporting for the CSI gathered is assumed in the CSI measurements that CSI request domain is not intended to trigger first service cell, the CSI request domain is used to trigger reporting for the existing CSI of LTE ReleaselO.For example, when the CSI request domain includes lbit information, then ' 0, represents not trigger non-periodic feedback, and ' 1 represents triggering serving cell c non-periodic feedback.

As a preferred embodiment of the present invention, the present embodiment can trigger the CSI non-periodic feedbacks that a variety of CSI measurements H do not have, and can realize many serving cells（Multicarrier）Non-periodic feedback measures the semi-static or dynamic switching for the CSI non-periodic feedbacks assumed with a variety of CSI.

For example, the CSI's that the first CSI measurements when the CSI request domain for indicating triggering first service cell are assumed reports or indicates that triggering second service cell and CSI measurements assume that the CSI's of collection unification reports or indicate that reporting for the CSI of set two is assumed in triggering second service cell and CSI measurements.

In the present embodiment, if the CSI request domain includes lbit information, ' 0, expression does not trigger non-periodic feedback, and T represents to trigger serving cell c non-periodic feedback；If the CSI request domain includes 2bit information, non-periodic feedback is triggered according to the expression of table five：

Table five

Second service cell described in table five and CSI measurements assume that collection unification and second service cell and CSI measurements assume that set two is to be allocated to UE by high-level signaling.

In the present embodiment, the CSI of the service cell set, which measures 4 Jia and sets to gather, includes at least one corresponding second measurement hypothesis of at least one second service cell； The second service cell is the serving cell in the service cell set, can be one or more, second service cell can be celll or cell2 as described.The non-periodic feedback that triggering second service cell and CSI measurements H in above-mentioned table five there are not collection to unify can assume the non-periodic feedback of set two for the blunt non-periodic feedback for setting collection unification of triggering cel l l and CSI measurement 4, above-mentioned triggering cel l2 and CSI measurement.

Before the user equipment (UE) receives dynamic signaling, in addition to：

The 3rd high-level signaling that the base station is sent is received, the 3rd high-level signaling includes the combined coding that the second service cell and corresponding second measurement of second service cell are assumed.

Wherein it is used to configure second service cell and CSI measurements assumes that collection unification or second service cell and CSI measurements assume that the 3rd high-level signaling of set two includes X bit (bit), the X is that maximum service cell number is multiplied by maximum CSI measurements hypothesis number, there are mapping relations in the bit, serving cell and CSI measurements, the X is the integer more than or equal to 1 between assuming.

The mapping relations that wherein described bit, serving cell and CSI measurements exist between assuming include but is not limited to：CSI measurements in one serving cell of each bit correspondences are assumed.The CSI measurements that for example in the serving cell that the 1st bit reference numeral is 1 numbering is 1 are assumed, the CSI measurements that numbering is 2 in the serving cell that 2nd bit reference numeral is 1 are assumed, by that analogy so that the CSI measurements in one serving cell of each bit correspondences are assumed.In another example, serving cell and CSI measurements are assumed to combine numbering, the serving cell that n-th of bit correspondence joint numbering is n is measured it is assumed that the definition mode for wherein combining numbering n includes but is not limited to CSI：Combine numbering n=(serving cell numbering -1) X maximums CSI measurements and assume that numbering or joint numbering n=(numbering -1 is assumed in CSI measurements) X maximum services cell number+serving cell numbering are assumed in number+CSI measurements.Bit values need not be fed back for the CSI that ' the 0' CSI measurements being expressed as in the corresponding serving cells of the bit are assumed, bit values are that the CSI that the CSI measurements that T is expressed as in the corresponding serving cells of the bit are assumed needs to feed back；Can also be ' 0 by bit values, the CSI that the CSI measurements being expressed as in the corresponding serving cells of the bit are assumed needs feedback, bit values are that the CSI that the CSI measurements that T is expressed as in the corresponding serving cells of the bit are assumed need not feed back.

Wherein it is used to configure second service cell and CSI measurements assumes that collection unification or another second service cell in service cell set and CSI measurements assume that the high-level signaling of set two includes Y byte (byte), Y For the integer for being more than or equal to 1 pre-set, such as Y=5 or 8.Wherein each byte one serving cell of correspondence combines numbering η with CSI measurement hypothesis, wherein joint numbering η definition mode includes but is not limited to：Combine numbering η=(serving cell numbering -1) X maximums CSI measurements and assume that numbering or joint numbering n=(numbering -1 is assumed in CSI measurements) X maximum services cell number+serving cell numbering are assumed in number+CSI measurements.If certain byte value that the high-level signaling includes is not in the span of the joint numbering n, then it represents that the byte is not used in triggering non-periodic feedback；If certain byte value S that the high-level signaling includes is in the span of the joint numbering n, then it represents that the serving cell that joint numbering is S measures the CSI assumed with CSI needs feedback.Such as 0 not in joint numbering n span, if byte value is ' 0, represents that the byte is not used in triggering non-periodic feedback；If byte value is ' η, and η is not 0, then it represents that the serving cell that joint numbering is η measures the CSI assumed with CSI needs feedback.

It is above-mentioned to measure for configuring second service cell and CSI measurements hypothesis collection unification or another second service cell in service cell set and CSI and assume that the high-level signaling for gathering two be that celll and CSI measurement hypothesis collection is unified or cell2 and CSI measurements are assumed to gather two high-level signaling for configuring

It should be noted that, it is all using lowest number as 1 citing that serving cell numbering, CSI measurements in the present embodiment, which assume that numbering, serving cell measure the numbering of combining assumed with CSI, but it is 1 or 0 or other numerical value the invention is not restricted to lowest number.

The present embodiment need not change dynamic signaling, it is only necessary to the description of dynamic signaling be changed by high-level signaling, so as to reduce dynamic signaling expense.For example, when the CSI request domain be used to indicating the CSI measurements of triggering first service cell assume the CSI of set report or indicate trigger CSI measurements in service cell set one assume set CSI report or indicate trigger reporting for CSI measurements hypothesis is gathered in second service set of cells two CSI.

In the present embodiment, the first service zonule CSI measurements assume that the definition of set assumes that the definition of set is identical with CSI measurements in first service zonule in foregoing one embodiment of the present invention, will not be repeated here.

In order to further reduce the expense of dynamic signaling, the present embodiment also includes：Partial status in the CSI request domain is numbered and/or frequency domain resource numbering and/or serving cell numbering expression by transmitting the time-domain resource in CSI request domain；Or the physical layer Uplink Shared Channel PUSCH of non-periodic feedback content is carried by sending particularly, the regular and described time-domain resource numbering and/or frequency domain resource numbering and/or serving cell numbering that the UE is configured according to predefined rule or the base station that receives by high-level signaling determine to need CSI in the serving cell fed back or service cell set to measure the CSI assumed.For example, UE determines whether non-periodic feedback according to the CSI request domain and feeds back the CSI of which service cell set, UE is according to pre- Regular and described time-domain resource numbering that the rule of definition or the base station that receives are configured by high-level signaling and

/ or frequency domain resource is numbered and/or serving cell numbering determines that needing the CSI fed back to measure assumes set.In another example the time-domain resource numbering and/or frequency domain resource numbering and/or serving cell numbering of assuming transmission CSI request domain are 1, the rule is：1 is even number or 1 is odd number.Now CSI request domain is 2bit, then as shown in table nine or table ten:The numerical value description in the regular CSI request domain of satisfaction

Specifically, the UE determines that the first threshold value N-PRB-CSI method can be according to the transmission mode of the UE or the number of serving cell：If UE only one of which serving cell and for CoMP transmission pattern, then the first threshold value is equal to the 3rd candidate's threshold value；If UE has multiple serving cells and is CoMP transmission pattern, then the first threshold value is equal to the 4th candidate's threshold value.Wherein described 4th candidate's threshold value is more than the 3rd candidate's threshold value.Specific 3rd candidate's threshold value and the 4th candidate's threshold value are predefined numerical value or assume that number is determined according to the 7th high-level signaling or maximum CSI measurements.Further, the UE assumes that the CSI of number or the service cell set that CSI measures hypothesis in set is surveyed according to the 3rd dynamic signaling or the measurement of the 8th high-level signaling or the CSI of the first service cell Amount assumes that number or the transmission mode or the number of serving cell of the UE are assumed in the number that CSI measurements are assumed in set or maximum CSI measurements, it is determined that the modulation system in during current PUSCH is reported transmitting uplink control information.
