Type I code book and Type II code book are defined in NR system.The anti-of Type II code book is given in table one and table two PMI feedback overhead when feedforward information composition and 32 port.Assuming that the wave beam that base station is configured with this code book merges number L=3, eventually End may feed back RI=1 (using 1 code book of rank) or RI=2 when carrying out CSI calculating (using 2 code book of rank).If terminal Determine that RI=1, total PMI are 192 bits, and if terminal determines that RI=2, total PMI are 370 bits.This illustrates its PMI's Dynamic range changes very greatly, its expense of the feedback of different RI differs 178 bits.Since base station can not be before obtaining RI information Know the payload size of CSI, therefore base station can only be terminal distribution uplink channel resources by some possible payload size.This money The distribution in source both needs to guarantee the precision of feedback, it is also desirable to guarantee the reasonable utilization of ascending resource.
The PMI feedback overhead (wideband portions) of one: 32 port type II code book of table
The PMI feedback overhead (subband part) of two: 32 port type II code book of table
In conclusion for the code book that NR system defines, the dynamic range of load overhead is larger, if according to maximum cost Uplink information resource is distributed, then may result in the larger waste of resource.If the ascending resource of distribution is smaller, not can guarantee anti- The precision of feedback.

Specific embodiment
The embodiment of the present application provides a kind of resource allocation, channel state information reporting method and device, provides to guarantee The effective use in source, and guarantee the feedback accuracy of CSI.
In mimo system, terminal is when reporting CSI information, load overhead dynamic change.Load for dynamic change is opened Pin, base station needs reasonable distribution ascending resource to realize the effective use of resource.
For in NR system, the larger problem of the feedback dynamic range of type (Type) II code book mentions the embodiment of the present application A kind of uplink channel resources distribution method and CSI feedback scheme out.
Specific process flow is illustrated below:
Step 1: base station determines Rank Indicator (RI) value set, is denoted as the first RI set；First RI gathers The set of one constant set either semi-static variation；Element number in first RI set can be 1 or greater than 1.
Alt-1: base station determines that the first RI gathers according to ability information, deployment scenario, professional qualification of UE etc., and passes through object Reason layer signaling or high-level signaling etc. are sent to terminal；Here high-level signaling is similar to and CSR signaling.Such as the capability reporting of UE Information show UE could support up 2 spread it is defeated, then the first RI set can be { 1,2 }；In another example declaration form stream in terminal is wished in base station CSI preferably to support MU-MIMO transmission, then the first RI set can be { 1 }.
Alt-2: the determination in the way of agreement of base station and terminal can be gathered with the first RI, such as be arranged in agreement, first RI collection is combined into { 1,2 ..., 7,8 }, does not at this moment need the feedback of terminal.
Step 2: base station selects one or more RI value from the first RI set, constitutes the 2nd RI and gathers, and described second RI set is the subset of the first RI set.The mode of base station selection is for example:
Selection based on professional qualification: for example the first RI collection is combined into { 1,2,3,4 }, base station according to the variation of business, such as The increase of system load determines the ratio for improving multi-subscriber dispatching, thus wish that terminal feeds back the channel state information of low rank, It then can choose the 2nd RI collection and be combined into { 1,2 }；
Based on reporting for terminal feedback: for example the first RI collection is combined into { 1,2,3,4 }, the void that terminal reports whithin a period of time Quasi- RI value (or the last virtual RI value reported) is 1, then the expected terminal in base station reports within following a period of time It will be low rank channel information, then base station, which can gather the 2nd RI, is determined as { 1,2 }.Base station is once to report before terminal Virtual RI is as reference, to determine that the 2nd RI gathers；According to the RI value in the 2nd RI set, provided for terminal distribution up channel Source so as to be further ensured that the effective use of uplink channel resources, and can also be further ensured that the essence of CSI feedback Degree.
Wherein, the RI value in the 2nd RI set can be discontinuous, such as the first RI collection is combined into { 1,2,3,4 }, and second RI set can be { 1,3 }.
Wherein, the 2nd RI set can be all RI for being less than or equal to some RI value (maximum RI value) in the first RI set What value was constituted, such as the first RI value set is { 1,2,3,4 }, base station determines that maximum RI value is according to the content of terminal previous feedback 2, then the 2nd RI collection is combined into { 1,2 }.
Step 3: the 2nd RI is gathered into relevant information and is notified to terminal in base station.Concrete mode is for example:
Mode one: base station all notifies the RI value in the 2nd RI set to terminal, such as the 2nd RI collection is combined into { 1,3 }, then The two values of base station all issue terminal；
Mode two: base station notifies maximum RI value to terminal, and the RI value composition of maximum RI value is less than or equal in first set Second set, such as the first RI value set are { 1,2,3,4 }, and base station determines that maximum RI value is according to the content of terminal previous feedback 2, then the 2nd RI collection is combined into { 1,2 }, and base station only needs to notify maximum RI value into that, to terminal, terminal can determine the 2nd RI collection It closes.The virtual RI that base station is once reported using before terminal is as reference, to determine that the 2nd RI gathers；According to the RI in the 2nd RI set Value is terminal distribution uplink channel resources, so as to be further ensured that the effective use of uplink channel resources, and may be used also To be further ensured that the precision of CSI feedback.It should be noted that virtual RI value described in the embodiment of the present application, be relative to For actual RI value, have no special meaning, only a RI value in the first RI set, the RI value with UE is practical adopts RI value is mutually distinguished.
For example, base station can be by transmission physical layer signaling or high-level signaling, or the signaling of aperiodic CSI triggering is sent, And the 2nd RI set relevant information can be carried wherein.If aperiodic CSI reports required stock number and terminal feedback RI value is related, then base station is that the resource of terminal distribution can be allocated according to the maximum RI value in the 2nd RI set.
Step 4: terminal receives the signaling that base station is sent, and determines the first RI set and the 2nd RI set.
Step 5: terminal calculates channel state information:
Terminal selects virtual RI value from the first RI set, has according to the channel condition and disturbed condition of base station to terminal Body selection method can be propped up using the method for prior art selection RI, the channel which represents base station to terminal The data fluxion for the parallel transmission held；
Step 6: terminal determines practical RI value:
Alt-1: the practical RI value is to be not more than the maximum RI value of virtual RI value in the 2nd RI set.
Alt-2: the practical RI value is terminal out of the 2nd RI set, according to the channel condition and interference stripe of base station to terminal The optimal RI value that the calculating such as part determine.
Step 7: terminal calculates CQI, PMI to the channel condition of terminal and disturbed condition etc. according to practical RI value and base station Deng (being also possible that CRI).For example, the first RI collection is combined into { 1,2 } for Alt-1, the 2nd RI collection is combined into { 1 }, terminal selection Virtual RI value is 2, then practical RI is 1.I.e. terminal calculates CQI and PMI according to RI=1, and the PMI that terminal calculates only corresponds to a number According to the pre-coding matrix of stream.The resource of uplink CSI feedback is gathered interior maximum RI value (1) according to the 2nd RI and is allocated, therefore Terminal can be transmitted according to the RI=1 CQI calculated and PMI in the resource distributed.For Alt-2, the first RI collection be combined into 1, 2,3,4 }, the 2nd RI collection is combined into { 1,2,3 }, and the virtual RI value that terminal selects is 4, is 2 into the practical RI for calculating determination is crossed.I.e. eventually End calculates CQI and PMI according to RI=2, and the PMI that terminal calculates corresponds to the pre-coding matrix of two data streams.Uplink CSI feedback Resource according to the 2nd RI gather in maximum RI value (3) be allocated, therefore terminal can be with according to the RI=2 CQI calculated and PMI It is transmitted in the resource distributed.
For Alt-1, terminal feeds back the information such as virtual RI value and CQI and PMI, as shown in Figure 1.Terminal feedback is virtual The bit number of RI value is determined by the element number in the first RI set, or is fixed value.
Or
For Alt-2, the virtual RI value of terminal feedback, the information such as practical RI value and CQI and PMI, as shown in Figure 2.Terminal The bit number for feeding back virtual RI value is determined by the element number in the first RI set, or is fixed value, the reality of terminal feedback The bit number of RI value is determined by the element number in the 2nd RI set, or is fixed value.
Step 8:
For Alt-1, base station receives the virtual RI value of terminal feedback, and determines practical RI value according to virtual RI value, practical RI value is to be not more than the maximum RI value of virtual RI value in the 2nd RI set.
For Alt-2, base station receives the virtual RI value and practical RI value of terminal feedback.
Base station receives the information such as the CQI and PMI of terminal feedback according to practical RI value.Including determining terminal according to practical RI value The bit number etc. of the information such as the CQI and PMI of feedback, is received.
