[0062] 本实施方式通过测量信道,将本次的信道的信息与上次测量得到的信道的信息进行预处理,预处理可以选择相似度测量、差分处理和相位角偏差等方式,得到本次的信道的信息与上次的信道的信息的差异值,并设置门限,当差异值低于门限时,进行下一步过程,如:按差异值组成反馈、基于码本的计算和协作基站基于测量的交互等;当差异值高于门限时,可以不进行反馈、不进行码本计算和减少交互等,因此,通过本实施方式可以有效的降低反馈开销,计算码本的复杂度,减少基站交互信息的容量,提高系统的性能。 [0062] The embodiment according to the present embodiment, the information channel information and the last measurement of the current channel obtained by measuring channel pretreatment, the pretreatment may be selected similarity measures, and the differential phase angle error handling, etc., to obtain this the difference value of the channel information and the previous channel information and the threshold is set, when the difference value is below the threshold, the next step process, such as: by a difference value consisting of feedback codebook based computing and collaboration base station based on measurement interaction and the like; if the difference value is above threshold, the feedback may not be performed, without reducing the codebook is calculated and interactions, etc., and therefore, can effectively reduce the feedback overhead by the present embodiment, the computational complexity of the codebook, the base station reduces interaction capacity information, improve system performance.

[0063] 本实施方式的信息处理方法包括以下几个步骤: [0063] The information processing method according to the present embodiment includes the following steps:

[0064] 步骤一:进行初始信道测量,得到并保存信道的信息; [0064] Step a: initial channel measurement, to obtain and save the information channel;

[0065] 信道测量包括:根据系统要求进行信道估计,信道估计可以是基站上行信道测量,也可以是下行信道测量;解调、反馈信道的信息,并保存本次的信道的信息。 [0065] The channel measurement comprises: according to the system requirements for channel estimation, channel estimation may be uplink channel sounding base station may be a downlink channel measurement; demodulating, feedback channels, and stores information of the current channel. [0066] 步骤二:在进行第二次到N次的信道测量后,保存信道的信息,并将得到的信道信息与上次测量的信道的信息进行预处理; [0066] Step Two: After performing the second to N-th channel measurement, to save information of a channel and channel information obtained by the information channel last measuring pretreatment;

[0067] 预处理可以是相似度测量、差分处理和相位角偏差等类似获得差异的处理过程。 [0067] The pretreatment may be a similarity measure, and the differential phase angle error handling processing and the like to obtain the difference. 预处理可以用于连续周期测量中,如,移动终端的信道测量和基站的信道测量等。 Pretreatment may be used for continuous measurement period, e.g., channel measurement channel measurement and the base station of the mobile terminal and the like.

[0068] 步骤三:将预处理得到的差异值与门限进行比较,根据差异值是否超出设定的门限的比较结果,判别下一步的处理。 [0068] Step 3: The pretreated obtained difference is compared with a threshold value, the difference value according to the comparison result exceeds the threshold setting, the next determination process.

[0069] 在完成第二次到N次的信道测量后,可以对本次的信道的信息与上次的信道的信息进行相似度测量,将相似度测量值作为预处理的差异值,将信道相似度M作为一致性判别的门限,将相似度测量值与信道相似度M进行比较。 [0069] After completion of the second measurement channel to N times, a similarity measure may be the information with previous information channel this channel, the difference value as the value of a similarity measure pretreatment, the channel M as determined consistency similarity threshold, a similarity measure the similarity value of the channel M are compared.

[0070] 相似度测量可以是已有的向量相似度判别方法,如,两个向量之间的Euclidean(欧几里得)距离,S卩:D(H(N),H(N+1)),两个向量的夹角的余弦函数和等相似度判别等方法。 [0070] The similarity measure may be a conventional vector similarity determination method, such as, Euclidean between two vectors (Euclidean) distance, S Jie: D (H (N), H (N + 1) ), and the like cosine function of the angle of the two vectors determining the degree of similarity or the like.

[0071] 门限值可以根据信道测量的统计信息确定,也可以根据如用户的移动速度、需要的反馈周期设定,码本之间的弦距离和反馈信道的负荷等因素进行调整,也可以根据已有的预编码矩阵的旋距离评估的差异确定和调整,例如,在反馈信道的负荷较大时,将门限调大,减少反馈颗粒度。 [0071] The threshold value may be statistical information channel measurement is determined, as may be in accordance with the moving speed of the user is required to set feedback cycle, load and other factors chord distance between the channel and the feedback codebook adjustment, may be the difference from the evaluation of conventional spin precoding matrix determined and adjusted, e.g., when a large load feedback channel, to transfer large threshold, reduce the feedback granularity.

[0072] 当两次信道测量的信道的信息的相似度测量值小于门限时,对于反馈和协作交互可以选择不交互,不进行PMI (Precoding Matrix Indicator,预编码矩阵)检索,直接利用上一次的计算结果;当两次信道测量的相似度测量值大于门限时,进行本次的计算。 [0072] When the similarity measurement information channel two channel measurement value less than the threshold, the feedback and collaborative interaction may choose not to interact, not PMI (Precoding Matrix Indicator, precoding matrix) retrieving, once the direct use calculation result; when the similarity measurement channel measurement channel twice greater than a threshold, for this calculation.

[0073] 对于终端向基站反馈信息的操作,可以采用信息压缩方法,如反馈的信息可以由预处理后的结果组成,如反馈预处理得到的差异值,对于协作基站可以仅交互信差异值,也可以按测量信息反馈和交互。 [0073] For the terminal operation information fed back to the base station, the information compression method may be employed, such as the feedback information may be a result of the pretreatment composition, pretreatment such as the difference value obtained by the feedback, the base station for cooperative interaction channel can only difference values, You can also press the measurement feedback and interaction.

[0083] 如图4所示,根据上一次UEl保留的测量结果H11 (N)、H12 (N),在获得新的H11 (N+1)、H12 (N+1)测量结果后,分别判别H11(N)与Hn(N+l),H12(N)与H12(N+1)的相似度,如计算两个信道向量之间的Euclidean距离,或进行两个向量的夹角余弦等处理。 [0083] As shown, the last measurement result UEl retention H11 (N), H12 (N) 4, after obtaining a new (N + 1), H12 (N + 1) measurements H11, respectively, is determined H11 (N) and Hn (N + l), H12 (N) and H12 (N + 1) similarity computing the Euclidean distance between two channel vector, or two vectors cosine of the angle processing such .

[0084] 如果UEl判断H11 (N)与H11 (N+1),H12 (N)与H12 (N+1)的相似度均小于系统设定的门限,认为信道没有变化,即本小区用户和协作小区的干扰用户都没有移动,则UEl此帧不反馈H11 (N+1)和H12 (N+1),或仅反馈部分测量值如H11 (N+1)或H12 (N+1)。 [0084] If UEl is determined H11 (N) and H11 (N + 1), H12 (N) and H12 (N + 1) degree of similarity is less than the system set threshold, that channel is not changed, i.e., the present cell user and interfering user cooperative cells are not moved, the UEl the frame is not fed H11 (N + 1) and H12 (N + 1), or only feedback section measurements as H11 (N + 1) or H12 (N + 1).

[0085] 基站根据UEl的反馈决定本次是否进行基站间的交互,如果此帧没有反馈,UEl的服务小区I,按上次调度的信息处理; [0085] The base station determines the current feedback UEL whether interaction between the base stations, if the frame is not feedback, UEL serving cell I, according to the scheduling information of the last process;

[0086] 如果此帧反馈H11 (N+1),小区I根据此帧反馈的本小区I的测量值和上次交互的邻小区的测量值进行本次的调度计算; [0086] If the feedback frame H11 (N + 1), I is the current cell scheduling is calculated from the measured values ​​of the neighbor cell measurement value of this cell according to the present frame and the previous feedback I interaction;

[0087] 如果此帧反馈H12 (N+1),小区I向小区2交互H12 (N+1),小区I根据上次调度结果进行处理,小区2根据交互的H12 (N+1)和小区2的反馈信息决定本次调度的结果。 [0087] If the feedback frame H12 (N + 1), cell I, cell I is processed according to the scheduling result to the previous cell interactions 2 H12 (N + 1), 2 H12 cell interaction (N + 1) and the cell according 2, the feedback information determination result of this scheduling. 同理,也可以推广的小区2,和更多的协作基站。 Similarly, cell 2 can be promoted, and more cooperative base stations.

[0088] 对于非协作基站,仅判别本基站的测量H11 (N+1)与上一次测量的H11 (N)的相似度,相似则此帧不反馈,或根据系统要求反馈,基站之间不存在信道测量的交互。 [0088] For non-cooperating base station, only the base station determines this measured H11 (N + 1) H11 (N) similarity with the previous measurement, then this frame is not similar to the feedback system according to claim or feedback, between the base station does channel measurement interaction exists.

[0089] UEl如果判断H12(N)与H12(N+1)相似度比较结果小于系统设定的门限,则认为干扰小区用户没有移动,则此帧不反馈H12 (N+1),而H11 (N)与Hn(N+l)的相似度比较结果大于门限,则反馈H11 (N+1)。 [0089] UEl If judged H12 (N) and H12 (N + 1) similarity comparison result is smaller than the threshold set by the system, the user is considered interfering cell does not move, then this frame is not feedback H12 (N + 1), and H11 (N) and Hn (N + l) is greater than a threshold similarity comparison result, the feedback H11 (N + 1).

[0090] 基站根据UEl的反馈决定是H11 (N+1)决定本次调度的结果,不进行基站间的交互,即小区I根据本次侧量结果和小区2的交互情况决定本次调度,即如果小区2交互信道H21 (N+1),小区I根据H11 (N+1)、H21 (N+1)决定本次调度结果,否则小区I根据H11 (N+1)、H21 (N)决定本次调度结果;同理,也可以推广的小区2,和更多的协作基站。 [0090] The base station is H11 (N + 1) determined based on the feedback decision UEl result of this scheduling, without interaction between the base stations, i.e. cells I decided to present scheduling depending on the interaction of this side amounts results and cell 2, i.e., if the cell 2 interaction channel H21 (N + 1), cell I, H21 (N + 1) decisions of the scheduling result according H11 (N + 1), or cell I according H11 (N + 1), H21 (N) the scheduling decision result; Similarly, cell 2 can be promoted, and more cooperative base stations.

[0091] 如果UEl判断H11(N)与Hn(N+l)的相似度小于设定的门限,则认为本小区用户没有移动,此帧不反馈H11 (N+1),而H12(N)与H12(N+1)的相似度大于设定的门限,则认为干扰用户信道发生变换,反馈H12 (N+1)。 [0091] If UEl is determined H11 (N) and Hn (N + l) of the degree of similarity is less than the set threshold, then that user does not move the current cell, the frame is not fed H11 (N + 1), and H12 (N) and H12 (N + 1) degree of similarity greater than a set threshold, the interference that the user channel conversion occurs, feedback H12 (N + 1).

[0092] 基站根据UEl的反馈决定本次是否进行基站间的交互,此帧反馈H12(N+1),小区I向小区2交互H12 (N+1),小区I根据小区2的交互情况决定调度结果,如果小区2向小区I交互H21 (N+1),则小区I根据H11 (N)和H21 (N+1)决定本次调度结果;否则,小区I根据H11 (N)、H21(N)决定本次调度结果;也可以推广的小区2,和更多的协作基站。 [0092] The base station according to UEl feedback decisions of the whether the interaction between the base, the frame feedback H12 (N + 1), cell I cell 2 interacting H12 (N + 1), cell I decided to depending on the interaction of the cell 2 scheduling result, if cell 2 interacting H21 (N + 1), then the cell I of this scheduling result H11 (N) and H21 (N + 1) determined according to a cell I; otherwise, cell I according H11 (N), H21 ( N) decisions of the scheduling results; may also promote cell 2, and more cooperative base stations.

[0098] 步骤2 :测量信息预处理及反馈; [0098] Step 2: preconditioning and measurement information feedback;

[0099] UEl根据上一次保留测量结果H11 (N),在获得H11 (N+1)后,先判别H11 (N)与Hn(N+l)的相似度,即进行两个信道向量之间的Euclidean距离,或两个向量的夹角余弦等处理。 Between [0099] retention time measurements H11 (N) according to the UEl, after obtaining H11 (N + 1), first determines H11 (N) and the degree of similarity Hn (N + l), i.e. two channel vectors for the Euclidean distance, cosine, or other processing of the two vectors.

[0100] 当H11 (N)与Hn(N+l)相似度小于设定的门限时,认为本小区用户没有移动,则此帧不反馈H11 (Ν+1) ο [0100] When H11 (N) and Hn (N + l) of the degree of similarity less than the set threshold, the cell that present the user does not move, then this frame is not feedback H11 (Ν + 1) ο

[0101] 当H11 (N)与Hn(N+l)相似度大于设定的门限时,认为本小区用户信道发生变化,此时,根据相似度的算法,如采用向量夹角的余弦,则反馈夹角余弦值,如采用两个向量之间的Euclidean 距离,即:D (H (N),H (N+1)),则反馈Euclidean 距离D。 [0101] When H11 (N) and Hn (N + l) of the degree of similarity greater than a set threshold, the cell that present the user changes a channel, this time, according to the similarity algorithms, such as the use of the cosine of the angle between vectors, the cosine of the angle feedback, such as using the Euclidean distance between two vectors, that is: D (H (N), H (N + 1)), the feedback Euclidean distance D.

[0102] 步骤3 :信息恢复与调度计算; [0102] Step 3: Calculation and scheduling information recovery;

[0103] 基站根据反馈的Euclidean距离D和保留的H(N)恢复出H(N+1),根据w' f Wi遍历码本集,获得最优的下发权值。 [0103] The base station according to the feedback recovery Euclidean distance D and H (N) retained an H (N + 1), according to w 'f Wi traverse codebook sets to obtain the optimal weight value is sent.

[0104] 实施例3 (信道测量与隐式反馈): [0104] Example 3 (measurement channel and implicit feedback):

[0105] 通常的码本计算是在码本集中选取码字w,遍历公式w' iH' Hwi,求迹(近似看成干扰强度的大小),如果选取邻区干扰信道,将最大值对应的w作为干扰特征矢量反馈WCI (worst companion PMIs,最坏的协作PMI),迹最小认为是BCI (best-companion PMI 最好的协作PMI);如果选取本小区信道,最大值对应的w作为最优PMI。 [0105] Generally codebook calculations are concentrated in a code selected codeword w, traversing formula w 'iH' Hwi, track seeking (approximate size as the interference strength), if the selected neighboring channel interference, the maximum value of the corresponding as an interference feedback feature vector w WCI (worst companion PMIs, the PMI collaboration worst), considered to be the minimum trace BCI (best-companion PMI the PMI best collaborative); if the selected channel of this cell, corresponding to the maximum value as the optimal w PMI. 当然也不局限于以上公式的码本选择,可以应用在所有码本遍历方法之前。 Of course, not limited to the above formula codebook selection may be applied before all codebook traversal methods.

[0106] 本实施例适用于单基站的码本选择,也适用协作基站的最优码本选择,以及最好或最坏的码本选择。 [0106] This embodiment is applicable to a single base station according to the present selection code, an optimal code is also applicable to the present cooperative station selection, or the worst and the best codebook selection. 本实施例以单基站的PMI为例说明,协作基站的干扰码本可以根据实施例I的干扰信道h12(n+i)计算。 In this embodiment, an example of the PMI single base station, the base station cooperating according to the interference code may be calculated based on the interference channel h12 (n + i) of the Example I embodiment.

[0107] 现有的计算方法,UE需要遍历码本集,复杂度较高,因此,本实施例先进行信道相似度的判别,如果信道相似,则反馈上一次保存的码本,否则,根据上式计算新的码本。 [0107] The conventional calculation method, the UE needs to traverse codebook set, high complexity, therefore, the present embodiment to discriminate similarity channel, if the channel is similar to the last saved the feedback codebook, otherwise, according to the new codebook is calculated.

[0112] 当H11 (N)与Hn(N+l)相似度小于设定的门限时,认为本小区用户没有移动,则此帧不计算PMI,以上一巾贞的PMI反馈,或不反馈。 [0112] When H11 (N) and Hn (N + l) of the degree of similarity less than a set threshold, that the user does not move the current cell, the PMI is not calculated for this frame, more than one towel Fok PMI feedback, or feedback.

[0113] 当H11(N)与Hn(N+l)的相似度大于设定的门限时,认为本小区用户信道发生变化,此时,遍历码本寻找最优码本,进行反馈,或根据Euclidean距离,在码本集中弦距离< Euclidean距离的码本中遍历,选取最优码本。 [0113] When H11 (N) and Hn (N + l) of the degree of similarity greater than a set threshold, the cell that present the user changes a channel, this time, to find the optimal traversal codebook codebook feedback, or according to Euclidean distance, the focus of the present codebook chordal distance <Euclidean distance traversal, selecting the optimal codebook.

[0119] 基站根据上一次UEl反馈的测量结果H11(N)和H12(N),在获得新H11 (N+1)和H12 (N+1)后,判别H11 (N)与Hn(N+l),H12(N)与H12 (N+1)的相似度,即进行两个信道向量之间的Euclidean距离,或两个向量的夹角余弦等处理。 [0119] a UEl feedback measurements H11 (N) on the base station in accordance with and H12 (N), after obtaining the new H11 (N + 1) and H12 (N + 1), determines H11 (N) and Hn (N + l), H12 (N) and H12 (N + 1) degree of similarity, namely the Euclidean distance between two channel vectors, two vectors or cosine like process.

[0120] 如果H12(N)与H12 (N+1)的相似度小于设定的门限,则小区I不向小区2进行基站间的交互。 [0120] If H12 (N) and H12 (N + 1) degree of similarity is less than the set threshold, the cell I do not interact between the base station 2 to a cell. 也可以推广的小区2和更多的协作基站。 It may also promote cell 2 and more cooperative base stations.
