Step 120: receiving end sends the first CSI, alternatively, receiving end determines the 2nd CSI according to the first CSI of acquisition, and sends the 2nd CSI.

For example, CSI process configuration information can be as shown in table 1.

1 CSI process configuration information of table

CSI process	Reference signal resource
CSI process 1	First reference signal resource
CSI process 2	Second reference signal resource
CSI process 3	Third reference signal resource

Can be seen that CSI process configuration information from the CSI process configuration information of table 1 includes 3 CSI processes, and for CSI process 1, according to the first reference signal resource, measuring reference signals obtain the first CSI1；For CSI process 2, according to the second reference signal resource, measuring reference signals obtain the first CSI2；For CSI process 3, according to third reference signal resource, measuring reference signals obtain the first CSI3；The first CSI1, the first CSI2 and the first CSI3 can be sent；Alternatively, can also determine the 2nd CSI according to the first CSI1, the first CSI2 and the first CSI3, the 2nd CSI is retransmited.

Above-mentioned is to one of step 100- step 120 for example, it's not limited to that.

In the prior art, regardless of under any scene, all including CQI (Channel Quality Indicator in the first CSI, channel quality instruction), but in some cases, it does not need to include CQI in the first CQI, if be still to according to the prior art include CQI if, there can be the wasting of resources, therefore, in order to avoid the wasting of resources, in the embodiment of the present invention, the first CSI does not include CQI.

In the prior art, a CSI process can only be associated with a reference signal resource, when the reference signal for needing to measure is more, then needs to configure multiple CSI processes.But since the CSI number of processes that each receiving end can configure is limited, in order to avoid CSI number of processes limits and improve resource utilization, at least one CSI process includes the first CSI process, and the first CSI process is associated at least two reference signal resources.

At this point, receiving end optionally, can be in the following way when obtaining a CSI in basis reference signal resource associated with any one CSI process:

Receiving end is according to each of at least two reference signal resource associated with the first CSI process Reference signal resource obtains the first CSI respectively.

For example, CSI process configuration information can be as shown in table 2.

2 CSI process configuration information of table

CSI process	Reference signal resource
CSI process 1	First reference signal resource, the second reference signal resource
CSI process 2	Third reference signal resource, the 4th reference signal resource
CSI process 3	5th reference signal resource, the 6th reference signal resource, the 7th reference signal resource

Can be seen that CSI process configuration information from the CSI process configuration information of table 1 includes 3 CSI processes, for CSI process 1, according to the first reference signal resource, measuring reference signals obtain the first CSI1, according to the second reference signal resource, measuring reference signals obtain the first CSI2；For CSI process 2, according to third reference signal resource, measuring reference signals obtain the first CSI3, and according to the 4th reference signal resource, measuring reference signals obtain the first CSI4；For CSI process 3, according to the 5th reference signal resource, measuring reference signals obtain the first CSI5, and according to the 6th reference signal resource, measuring reference signals obtain the first CSI6, and according to the 7th reference signal resource, measuring reference signals obtain the first CSI7.

In the embodiment of the present invention, optionally, reference signal resource associated with the same CSI process includes the first reference signal resource and the second reference signal resource, it is not identical as content included by the first CSI that is obtained according to the second reference signal resource according to the first CSI that the first reference signal resource obtains.

Wherein, content included by first CSI can be following at least one information: RI (Rank Indicator, order instruction), PMI (Precoding Matrix Indicator, pre-coding matrix instruction), CQI, wave beam indicate BI (Beam Indicator, wave beam instruction), and PI (instruction of CSI-Process indicator, CSI process).

For example, the first CSI1 includes PMI, the first CSI2 includes RI and CQI；Alternatively, the first CSI1 includes PMI, the first CSI2 includes PMI and CQI.

Certainly, when a CSI process is associated at least two reference signal resources, according to each reference signal resource obtain the first CSI included by parameter be identical, but parameter specifically be worth can difference.

For example, CSI process is associated with 3 reference signal resources: the first reference signal resource, the second reference signal resource and third reference signal resource obtain the first CSI1 according to the first reference signal resource；According to the second reference signal resource, the first CSI2 is obtained；According to third reference signal resource, the first CSI3 is obtained, the first CSI1 includes RI1/PMI1, CQI1；First CSI2 includes RI2/PMI2, CQI2；First CSI3 includes RI3/PMI3, CQI3, although the first CSI, the first CSI2 and the first CSI3 include RI/PMI and CQI, but the occurrence of RI1/PMI1, RI2/PMI2 and RI3/PMI3 can be different, the occurrence of CQI1, CQI2 and CQI3 can also be different.

In the embodiment of the present invention, optionally, the following information of at least one corresponding to the reference signal resource different from any two in associated at least two reference signal resource of any one CSI process is different:

Temporal information, frequency information, antenna port information, cycle information, precoding information, OCC (Orthogonal Cover Code, orthogonal mask) code information.

For example, there is 2 reference signal resources: the first reference signal resource, the second reference signal resource, in which: the first reference signal resource and the corresponding frequency information of the second reference signal resource are different；Alternatively, being also possible to the first reference signal resource and the corresponding antenna port information difference of the second reference signal resource；Alternatively, being also possible to the first reference signal resource and the corresponding cycle information difference of the second reference signal resource；Alternatively, being also possible to the first reference signal resource and the corresponding precoding information difference of the second reference signal resource.

In the prior art, if each reference signal resource will feed back CQI, but, waste of resource can be haveed the defects that if still feeding back CQI by not needing feedback CQI in some cases, therefore, in order to avoid the wasting of resources, if a CSI process is associated at least two reference signal resources, the first CSI of at least one of the first CSI obtained respectively according at least two reference signal resources does not include CQI.

Such as, CSI process 1 is associated with the first reference signal resource, the second reference signal resource and third reference signal resource, the first CSI1 is obtained according to the first reference signal resource, the first CSI2 is obtained according to the second reference signal resource, the first CSI3 is obtained according to third reference signal resource, if not needing to include CQI in CSI under current scene, then in order to avoid the wasting of resources, can have a CSI in first CSI1, the first CSI2 and the first CSI3 does not include CQI, or, it can not also include CQI there are two CSI Alternatively, can not also include CQI there are three CSI.

In the embodiment of the present invention, CSI process configuration information includes at least two CSI processes, and any one CSI process at least two CSI processes is associated at least one reference signal resource.

At this point, according to reference signal resource associated with any one CSI process, it, optionally, can be in the following way when obtaining a CSI:

That is if a CSI process is associated with a reference signal resource, the first CSI is obtained, if a CSI process is associated with N number of reference signal resource, obtains N number of first CSI, N is more than or equal to 2.

For example, CSI process configuration information can be as shown in table 3.

3 CSI process configuration information of table

CSI process	Reference signal resource
CSI process 1	First reference signal resource
CSI process 2	Second reference signal resource, third reference signal resource
CSI process 3	4th reference signal resource, the 5th reference signal resource, the 6th reference signal resource

Can be seen that CSI process configuration information from the CSI process configuration information of table 3 includes 3 CSI processes, and for CSI process 1, according to the first reference signal resource, measuring reference signals obtain the first CSI1；For CSI process 2, according to the second reference signal resource, measuring reference signals obtain the first CSI2, and according to third reference signal resource, measuring reference signals obtain the first CSI3；For CSI process 3, according to the 4th reference signal resource, measuring reference signals obtain the first CSI4；, according to the 5th reference signal resource, measuring reference signals obtain the first CSI5, and according to the 6th reference signal resource, measuring reference signals obtain the first CSI6.

Then, first CSI1, the first CSI2, the first CSI3, the first CSI4, the first CSI5 and the first CSI6 can be fed back, or, the first CSI is selected from the first CSI1, the first CSI2, the first CSI3, the first CSI4, the first CSI5 and the first CSI6 to be fed back, alternatively, by the first CSI1, the first CSI2, the first CSI3, the first CSI4, the first CSI5 and the first CSI6 synthesize into Row feedback.

Wherein, when selecting a CSI from least two the oneth CSI obtained, qualified first CSI can be selected from least two the oneth CSI obtained, the first CSI that qualified first CSI is alternatively gone out.

Wherein, qualified first CSI can satisfy the first CSI of at least one following condition:

CQI is maximum value, handling capacity is maximum value, SINR (Signal to Interference plus Noise Ratio, Signal to Interference plus Noise Ratio) is maximum value.

Still it is illustrated for CSI process configuration information described in the table 3.

Such as, according to CSI process configuration information described in table 3, it can be concluded that 6 the first CSI: the one CSI1, the first CSI2, the first CSI3, the first CSI4, the first CSI5, the first CSI6, wherein, the handling capacity of the first CSI3 is maximum value in 6 the first CSI, then using the first CSI3 as the 2nd CSI, and the 2nd CSI is sent；If the handling capacity of the first CSI6 is maximum value, using the first CSI6 as the 2nd CSI, and the 2nd CSI is sent.

In another example obtaining the first CSI1 according to reference signal resource, the first CSI2, the first CSI1 correspond to horizontal direction channel parameter, and the first CSI2 is corresponding vertically to channel parameter；Wherein, the first CSI1 includes RI1, PMI1, and the first CSI2 includes RI2, PMI2；Wherein, PMI1 corresponds to pre-coding matrix W1, and PMI2 corresponds to pre-coding matrix W2, then the corresponding pre-coding matrix of PMI in the 2nd CSI isWherein,For Crow internal medicine operator, the corresponding RI of the 2nd CSI can also be obtained by R11*RI2, wherein * is multiplication operator.Optionally, the corresponding CQI of the 2nd CSI is obtained according to the corresponding PMI of the 2nd CSI.

Wherein, as soon as when pre-coding matrix W1 is column, the corresponding not instead of matrix of PMI1, a vector, therefore, PMI1 can be corresponding with pre-coding matrix, be also possible to opposite with vector It answers.

Similarly, as soon as when pre-coding matrix W2 is column, the corresponding not instead of matrix of PMI2, a vector, therefore, PMI2 can be corresponding with pre-coding matrix, be also possible to corresponding with vector.

It should be noted that, first CSI1 of foregoing description, the first CSI2 respectively correspond horizontal direction channel parameter and vertically to channel parameters, only a kind of particular situation, horizontal direction channel parameter can only be corresponded to by being not limited to the first CSI1, and the first CSI2 can only be corresponded to vertically to channel parameter.

Wherein, content included by the 2nd CSI can be following at least one information:

RI, PMI, CQI, BI and PI.

Under some scenes, the 2nd CSI of transmission does not need to include CQI, if still including CQI, can have the defects that waste of resource, therefore, in order to avoid the wasting of resources, the 2nd CSI does not include CQI.

Do not include CQI described above is the first CSI or the 2nd CSI, still, the first CSI or the 2nd CSI may include following content:

For example, the first CSI includes RI and/or PMI；Alternatively, the 2nd CSI includes RI and/or PMI.

In the prior art, the CSI that each CSI process obtains will be fed back, for example, CSI process 1 obtains a CSI, it is the first CSI1；CSI process 2 obtains a CSI, is the first CSI2；CSI process 3 obtains a CSI, is the first CSI3；First CSI1, first CSI2 and the first CSI3 are required to be fed back, first CSI1 is fed back on the corresponding feedback resources 1 of CSI process 1, first CSI2 is fed back on the corresponding feedback resources 2 of CSI process 2, first CSI3 is fed back on the corresponding feedback resources 3 of CSI process 3, but, under some scenes, it only needs from the first CSI1, the first CSI is selected in first CSI2 and the first CSI3 to be fed back, either by the first CSI1, first CSI2 and the first CSI3 synthesizes the 2nd CSI and is fed back, so, at this time, just corresponding feedback resources need not be configured to each CSI process.

Therefore, in order to avoid the wasting of resources, can be more than or equal to by 1, n and be more than or equal to 1 and be less than m for n associated feedback resources of m CSI process configuration, m.

Such as, CSI process configuration information includes 2 CSI processes, first CSI process is associated with the first reference signal resource and feedback resources, 2nd CSI process is associated with the second reference signal resource, first CSI process is according to the first reference signal resource, the first CSI1 is obtained, the 2nd CSI process obtains the first CSI2 according to the second reference signal resource；Selecting qualified first CSI from the first CSI1 and the first CSI2 is the first CSI1, then feeds back the first CSI1 on feedback resources associated with the first CSI process；Alternatively, selecting qualified first CSI from the first CSI1 and the first CSI2 is the first CSI2, then the first CSI2 is fed back on feedback resources associated with the first CSI process；Alternatively, the first CSI1 and the first CSI2 is synthesized the 2nd CSI, then the 2nd CSI is fed back on feedback resources associated with the first CSI process.

Further, it is also necessary to illustrate that the first CSI of feedback is which CSI process obtains, for example, the mark of the CSI process of the first CSI fed back can be carried.

It is of course also possible to CSI process associated with feedback resources, and CSI process associated with the first CSI of feedback, in the case where not being same CSI process, besides the first CSI of bright feedback is which CSI process obtains.

For example, CSI process configuration information includes 2 CSI processes, 2 CSI processes have corresponding mark, and the first CSI process is associated with the first reference signal resource and feedback resources, the 2nd CSI process and Second reference signal resource is associated, first CSI process obtains the first CSI1, the 2nd CSI process is according to the second reference signal resource according to the first reference signal resource, obtain the first CSI2, that select from the first CSI1 and the first CSI2 is the first CSI1, then feeds back the first CSI1 on feedback resources associated with the first CSI process, at this time, it can be when feeding back a CSI1, the mark of the first CSI process is carried, it is of course also possible to not carry；That select from the first CSI1 and the first CSI2 is the first CSI2, then feeds back the first CSI2 on feedback resources associated with the first CSI process, at this point it is possible to carry the mark of the 2nd CSI process when feeding back a CSI2.

It can find out from the example above, if the first CSI process and the 2nd CSI process all configure feedback resources, the case where there are the wastings of resources, therefore, if only one CSI process in only the first CSI process and the 2nd CSI process is related to feedback resources, the wasting of resources can be avoided, the utilization rate of resource is improved.

When a CSI process is associated with multiple reference signal resources, if it is not known that if the CSI process is associated with several reference signal resources, all reference signal resources associated with the CSI process may not be utilized to go to measure, in this way, the case where there are the wastings of resources.

Such as, first CSI process is associated with 2 reference signal resources: the first reference signal resource and the second reference signal resource, it is associated with 2 reference signal resources due to not knowing, only measured according to the first reference signal resource, obtain the first CSI1, in this way, the case where the second reference signal resource there is waste.

Therefore, in order to avoid the wasting of resources, CSI process configuration information further include distinguishing the quantity of associated reference signal resource with each of at least one CSI process CSI process；

Each of reference signal resource according to quantity corresponding with any one CSI process reference signal resource, obtains corresponding first CSI respectively.
