The mode that the code book (including single panel code book and more panel code books) of type I is based on beam selection generates.Its In, single panel code book of type I selects a wave beam from the wave beam grouping that M wave beam is constituted, and to the wave beam selected into Horizontal phasing control obtains, and base station can configure M=1 or M=4；More panel code books of type I based on single panel code book, The phase adjustment between panel is increased, this phase adjustment is according to the requirement profit distribution model 1 and mode 2 of precision, wherein mode 1 Corresponding low feedback overhead, the corresponding high feedback overhead of mode 2.
The code book of Type II is generated based on the mode that wave beam merges, by L wave beam after the weighting of amplitude and phase It generates, L=2, L=3 or L=4 can be configured.
When carrying out the acquisition of CSI (Channel State Information, channel state information), terminal is according to base Stand configuration code book type carry out RI (Rank Indication, order instruction) PMI ((Precoding Matrix Indicator, pre-coding matrix instruction) CQI (Channel Quality Indicator, channel quality instruction) calculating. If base station Configuration Type II code book for when feeding back in high precision, it is desirable that terminal has the ability for supporting high computation complexity.Figure one In give the PMI feedback overhead of 32 port type II code books, wave beam number L and the Rank value merged with for wave beam (data fluxion) is directly related.Wherein, each PMI feedback overhead consists of two parts, wideband portions and subband part, figure one with It is illustrated for 1 broadband and 10 subbands, by it is found that for L=2 and L=4, feedback overhead difference is close to 1 in figure Times, having very big difference is required to the computing capability of terminal.And for type I code book, computing capability difference is equally existed to terminal Requirement.Such as more panel code books for type I, there is also modes 1 (low feedback overhead) and mode 2 (high feedback overhead) Two class of code book, with different computation complexities.And the wave beam number for single panel code book of type I, in wave beam grouping When M=1 or 4, it may have different computation complexities.That is, for certain types of code book, it is at different conditions, right The computing capability of terminal requires variant.
In LTE (Long Term Evolution, long term evolution) system, base station by the method for codebook subset constraint, Limiting terminal without using in code book certain pre-coding matrixes, without using the certain wave beams for constituting code book or without using a certain The code word of Rank value reduces the computation complexity of terminal.
Specifically, the codebook subset constraint method in LTE system is voluntarily to determine constraint criterion by base station, and pass through letter It enables and informs terminal.But since base station is not aware that the computing capability of terminal, this codebook subset constraint may be beyond terminal Computing capability causes the calculating time-consuming of terminal larger, increases feedback delay, influences system performance.
As it can be seen that there are accuracy is lower for code book constrained procedure in the prior art, or even influences the technology of system performance and ask Topic.

S102: based at least one described parameter information, for terminal configuration and the matched code of the computation complexity This subset restriction information；
S103: the configuration information of the codebook subset constraint information and codebook parameter is sent to by the end by signaling End.
In the specific implementation process, step S101 to step S103's the specific implementation process is as follows:
Firstly, the base station receives at least one parameter information that terminal is sent, wherein at least one described parameter information The computation complexity of the terminal can be characterized.The computation complexity is higher, it is meant that requires to get over to the computing capability of terminal It is high.For example, the maximum data fluxion that the terminal reports it that can support to the base station, as maximum data fluxion is corresponding The Rank value the big, means that the computing capability of the terminal is stronger.Then, based at least one described parameter information, for institute State the instruction of terminal configuration and the matched codebook subset constraint information of the computation complexity.Such as more panel codes of type I This, configures it and uses the lower low overhead code book of computation complexity, constrains its maximum data fluxion as 3 i.e. Rank=3.Root simultaneously The constraint demand to candidate beam reported according to the terminal configures a beam subset for generating type I code book.Then, The above-mentioned information for terminal configuration is passed through terminal described in signaled by the base station.

Receive the terminal parameter information for being used to characterize terminal processing capacity that terminal is sent；And/or
Receive the codebook subset constraint auxiliary information that terminal is sent；And/or
It receives the codebook parameter that terminal is sent and configures auxiliary information.
That is, at least one described parameter information includes the terminal parameter information, codebook subset constraint auxiliary letter Breath, codebook parameter configure the combination of any one or more information in auxiliary information.Wherein, the codebook subset constraint auxiliary Information can be one or more of the constraint of data fluxion, candidate beam constraint and twiddle factor constraint.In addition, may be used also Be twiddle factor constraint, phase coefficient constraint, range coefficient constraint, wait codebook parameters other values constrain in one or It is multiple, it just different one has been illustrated herein.The codebook parameter configuration auxiliary information merges number, wave beam group by maximum wave beam Auxiliary information composition in interior wave beam number, codebooks modes parameter.Certainly, for those skilled in the art, At least one described parameter information can also be designed as needed, just different one had been illustrated herein.
In the specific implementation process, for those skilled in the art, when the value of data fluxion means more greatly Computation complexity is bigger, and candidate beam means that computation complexity is bigger, and maximum wave beam merges that number to be meaned to count It is bigger to calculate complexity.It is low overhead code book when codebooks modes are mode 1, it is meant that calculate complicated smaller.It is in codebooks modes It is high expense code book when mode 2, it is meant that computation complexity is bigger.For other situations, just do not repeat one by one.
In embodiments of the present invention, the codebook parameter configuration auxiliary information for receiving terminal and sending, comprising:
Receive the terminal transmission includes that maximum wave beam merges number, the wave beam number in wave beam group, codebooks modes ginseng The codebook parameter of an auxiliary information in number configures auxiliary information.
In addition, in embodiments of the present invention, when at least one described parameter information is the terminal parameter information, please join It examines Fig. 3, step S102: based at least one described parameter information, being configured for the terminal matched with the computation complexity Codebook subset constraint information, comprising:
S201: the terminal processing capacity information that the terminal is sent is received, wherein the terminal processing capacity information is used In the terminal processing capacity for characterizing the terminal；
S202: it is based on the terminal processing capacity information, determines the computation complexity of the terminal；
S203: it is based on the computation complexity, determines that codebook parameter can selected value set；
S204: can the corresponding codebook subset constraint information of selected value set with the codebook parameter for terminal configuration.
In embodiments of the present invention, S202: being based on the terminal processing capacity information, determines that the calculating of the terminal is complicated Degree, comprising: first pair between the computation complexity that can be supported by the preset terminal processing capacity information and the terminal It should be related to, determine computation complexity corresponding with the terminal processing capacity information.Certainly, come for those skilled in the art It says, can also be determined outside the computation complexity of the terminal, can also be set as needed using corresponding relationship described above The technical solution of other forms is counted to determine the computation complexity of the terminal, just different one is had been illustrated herein.
In embodiments of the present invention, S203: be based on the computation complexity, determine codebook parameter can selected value set, packet It includes: second corresponding can be closed between selected value set by predefining computation complexity that the terminal can be supported and codebook parameter System determines that codebook parameter corresponding with the computation complexity can selected value set.Certainly, come for those skilled in the art It says, can also determine that the codebook parameter can be outside selected value set using corresponding relationship described above, it can also be according to need Design the technical solution of other forms determine the codebook parameter can selected value set, herein just it is different one illustrate ?.
To determine the computation complexity of the terminal using the first corresponding relationship as described above, using as described above the Two corresponding relationships determine that the codebook parameter can be for selected value set, and the specific implementation process of step S201 to step S204 is such as Under:
Firstly, the base station predefines the terminal processing capacity and the preset terminal processing capacity and the end Hold the corresponding relationship between the computation complexity that can be supported；It is defined according to the Type II code book of NR system, the structure of Type II code book Make is from S candidate beam (B0, B1... ..., Bs-1) in, select L wave beam to carry out linear combining, and from K twiddle factor A factor pair wave beam is selected to be rotated to obtain.The predefined terminal processing capacity of system is divided into N number of ability rating, and wherein N is Positive integer more than or equal to 1, as shown in Figure 4.Dividing for this N number of ability rating can be according to the function of terminal, characteristic etc. It divides, each terminal corresponds to one of ability rating.The corresponding ability rating of each terminal predefines a calculatings complexity Spend parameter, i.e., the corresponding relationship between the computation complexity that preset terminal processing capacity and the terminal can be supported.This parameter can It is divided into T grade with the computing capability according to terminal.As T=3, as shown in Figure 4, the computing capability of terminal be divided into it is low, in With high three grades.Certainly, those skilled in the art can also divide the computing capability of terminal according to actual needs, herein Different one has been illustrated.After the computation complexity for determining the terminal, the base station calculates again according to system is predefined Miscellaneous degree and codebook parameter can the second corresponding relationship between selected value set, configured for the terminal corresponding with its computation complexity Codebook parameter can the corresponding codebook subset constraint information of selected value set.It is complicated to be illustrated in figure 5 the calculating that the terminal is supported One of mapping table between degree and the optional value set of Type II codebook parameter.Certainly, those skilled in the art may be used also With for different type codes designed originally the terminal computation complexity and codebook parameter can corresponding between selected value set close System, does not just repeat one by one herein.
In the specific implementation process, when it is 3 that the base station, which receives the terminal processing capacity grade that the terminal reports, lead to Corresponding relationship documented by Fig. 4 is crossed, the base station determines the computation complexity that it is supported for middle rank.
It is intermediate computation complexity according to the terminal when the base station is the terminal Configuration Type II code book, and The corresponding relationship in conjunction with documented by Fig. 5, the base station determine that the wave beam in codebook parameter merges number L and can only configure 2 or 3, together When S candidate beam of construction this type II code book is constrained, make a wave beams to be combined of L can only be from S candidate beam A beam subset (B0, B1..., BS/2-1) in chosen.
