Description
本發明是屬於通信技術領域,特別是關於一種通道狀態資訊回饋和接收方法、裝置。 The invention belongs to the field of communication technology, and in particular relates to a channel state information feedback and receiving method and device.
多天線系統中,基地台(evolved Node B,eNB)側需要可靠的通道資訊(Channel State Information,CSI)進行資料調度、信號傳輸等處理。CSI是由使用者設備(User Equipment,UE)通過下行導頻信號測量得到的,並通過回饋方式通知給eNB。假設一個多輸入多輸出(Multiple Input Multiple Output,MIMO)系統中包括Nt個傳輸天線和Nr個接收天線,則MIMO信號為Nt×Nr的複數矩陣。在實際通信系統中,UE並不回饋Nt×Nr個複數資訊給eNB側來實現CSI回饋。MIMO回饋賦形技術大多數基於隱性(implicit)回饋方案,系統預先定義一組可能的預編碼矩陣(precoding matrix,也稱為賦形矩陣),稱為碼本(codebook),UE從codebook中選擇最佳的賦形矩陣並回饋其索引,即預編碼矩陣指標(Precoding Matrix Indicator,PMI),並同時回饋在使用該PMI對應的賦形矩陣進行賦形時接收到的通道品質指標(Channel Quality Indicator,CQI)。 In a multi-antenna system, the base station (evolved Node B, eNB) side needs reliable channel state information (CSI) for data scheduling and signal transmission. CSI is measured by the user equipment (User Equipment, UE) through the downlink pilot signal, and is notified to the eNB through a feedback method. Assuming that a multiple input multiple output (Multiple Input Multiple Output, MIMO) system includes Nt transmission antennas and Nr reception antennas, the MIMO signal is a complex matrix of Nt × Nr. In an actual communication system, the UE does not feed back Nt × Nr complex information to the eNB side to implement CSI feedback. Most of the MIMO feedback shaping techniques are based on implicit feedback schemes. The system pre-defines a set of possible precoding matrices (also known as shaping matrices), called codebooks, which the UE uses from the codebook. Select the best shaping matrix and feed back its index, which is the Precoding Matrix Indicator (PMI), and at the same time feedback the channel quality index (Channel Quality Index) received when shaping using the shaping matrix corresponding to the PMI. Indicator, CQI).
可選的,UE也可以回饋秩指示(Rank Indication,RI)用於通知eNB可以接收資料流程數的資訊。例如,UE回饋RI值為r,PMI值為k, 代表UE建議eNB使用rank-r的codebook中的第k個賦形矩陣進行賦形,rank-r的codebook包括一組維度為Nt×r的賦形矩陣。 Optionally, the UE may also feed back a Rank Indication (RI) to inform the eNB that it can receive information about the number of data flows. For example, the UE feedback RI value is r, and the PMI value is k, On behalf of the UE, it is suggested that the eNB use the k-th shaping matrix in the rank-r codebook for shaping. The rank-r codebook includes a set of shaping matrices with dimensions Nt × r.
現有的MIMO回饋方案(feedback)基於閉環(closed-loop)設計,針對每一個回饋的時頻資源,比如子帶(subband),包含一組實體資源區塊對(PRB pairs;Physical Resource Block,PRB),UE回饋最佳的PMI/CQI/RI。Closed-loop feedback中假設系統通道較為穩定,這樣在子訊框n(subframe n)回饋的通道,可以在k個subframe之後eNB進行實際資料發送的時刻較好的反映子訊框n+k的通道資訊。如果subframe n的通道H(n)和subframe n+k的通道H(n+k)相差不大,則closed-loop MIMO的性能較為理想。但是在現實系統中,這個假設不一定成立,導致MIMO性能有很大下降。例如,通道變化快慢和UE移動速度相關,當UE速度較大時(比如在汽車、或高速鐵路上),通道在每個子訊框變化都很大,導致H(n)和H(n+k)相關性下降。又如,UE測量下行通道,回饋CSI,eNB使用該CSI進行調度傳輸存在一定的延遲時間,總共為k個子訊框,長期演進(Long Term Evolution,LTE)系統中每個子訊框為1ms,所以總共延遲時間為kms。當k較大時候,closed-loop MIMO系統性能下降明顯。 The existing MIMO feedback scheme is based on a closed-loop design. For each feedback time-frequency resource, such as subband, it contains a set of physical resource block pairs (PRB pairs; Physical Resource Block, PRB) ), The UE returns the best PMI / CQI / RI. Closed-loop feedback assumes that the system channel is relatively stable, so that the channel fed back in subframe n (subframe n) can better reflect the channel of subframe n + k after the actual data transmission by the eNB after k subframes Information. If the channel H (n) of subframe n is not much different from the channel H (n + k) of subframe n + k, the performance of closed-loop MIMO is ideal. However, in a real system, this assumption is not necessarily true, resulting in a significant decrease in MIMO performance. For example, the channel change speed is related to the UE moving speed. When the UE speed is high (such as in a car or high-speed railway), the channel changes greatly in each subframe, resulting in H (n) and H (n + k ) Correlation decreases. For another example, the UE measures the downlink channel and feeds back the CSI. The eNB uses the CSI to schedule transmission with a certain delay time. There are k subframes in total. In the Long Term Evolution (LTE) system, each subframe is 1 ms, so The total delay time is kms. When k is large, the performance of the closed-loop MIMO system drops significantly.
綜上所述,現有MIMO回饋方案在UE速度較大時,可靠性不高,並且回饋時刻和資料傳輸時刻之間存在時間延遲,從而導致MIMO系統性能下降。 In summary, the existing MIMO feedback scheme has low reliability when the UE speed is high, and there is a time delay between the feedback time and the data transmission time, which results in the degradation of MIMO system performance.
本發明實施例提供了一種通道狀態資訊回饋和資料傳輸方法、裝置,用於解決現有MIMO回饋方案在UE速度較大時,可靠性不高, 並且回饋時刻和資料傳輸時刻之間存在時間延遲,從而導致MIMO系統性能下降的問題。 Embodiments of the present invention provide a channel status information feedback and data transmission method and device, which are used to solve the problem that the existing MIMO feedback scheme is not reliable when the UE speed is large, And there is a time delay between the feedback time and the data transmission time, which leads to the problem of degraded MIMO system performance.

In this embodiment of the present invention, one time-frequency resource is divided into 1 precoding unit, and different precoding units in the time-frequency resource are shaped using different precoding matrices, that is, multiple different ones are used in one time-frequency resource. The precoding matrix is shaped, the channel is averaged by multiple precoding matrices, even if the channel changes in the time domain, because the CQI is obtained by the terminal traversing different precoding matrix measurements Therefore, the CQI can still accurately reflect the actual status of the channel. In high-speed scenarios or other channels where the channel is unstable, the effect of the feedback time delay is very small, which improves the system robustness.

The terminal uses different precoding matrices in the precoding matrix group corresponding to the shaping pattern according to the determined shaping pattern, and one of at least one time-frequency resource. Precoding units (English: precoding units) are shaped, where the time-frequency resource is divided into 1 precoding unit, and the shaping mode represents the 1 precoding unit in the time-frequency resource corresponding to the shaping mode The mapping relationship between the precoding matrices in the precoding matrix group, I is an integer greater than 1.
本步驟中,一個時頻資源被劃分成I個預編碼單元,終端根據確定的賦形模式,在不同的預編碼單元上採用不同的預編碼矩陣進行賦形。 In this step, one time-frequency resource is divided into 1 precoding unit, and the terminal uses different precoding matrices on different precoding units to perform shaping according to the determined shaping mode.
本發明實施例中,每個賦形模式對應一個預編碼矩陣組,記為V={V1,V2,...,VM},M表示預編碼矩陣組中包含的預編碼矩陣的個數;若N賦形模式的個數大於1,不同賦形模式可以對應相同的預編碼矩陣組,也可以對應不同的預編碼矩陣組;若賦形模式的個數N大於1,不同的賦形模式可以對應不同的預編碼矩陣組,且所表徵的時頻資源中的I個預編碼單元與賦形模式對應的預編碼矩陣組中的預編碼矩陣之間的映射關係相同;不同的賦形模式也可以對應相同的預編碼矩陣組,且所表徵的時頻資源中的I個預編碼單元與賦形模式對應的預編碼矩陣組中的預編碼矩陣之間的映射關係不同;不同的賦形模式還可以對應不同的預編碼矩陣組,且所表徵的時頻資源中的I個預編碼單元與賦形模式對應的預編碼矩陣組中的預編碼矩陣之間的映射關係不同。 In the embodiment of the present invention, each shaping pattern corresponds to a precoding matrix group, which is denoted as V = {V 1 , V 2 , ..., V M }, where M represents the precoding matrix included in the precoding matrix group Number; if the number of N forming patterns is greater than 1, different forming patterns can correspond to the same precoding matrix group or different precoding matrix groups; if the number of forming patterns N is greater than 1, different The shaping pattern can correspond to different groups of precoding matrices, and the mapping relationship between the one precoding unit in the characterized time-frequency resource and the precoding matrix in the group of precoding matrices corresponding to the shaping mode is the same; different The shaping mode can also correspond to the same precoding matrix group, and the mapping relationship between the 1 precoding unit in the characterized time-frequency resource and the precoding matrix in the precoding matrix group corresponding to the shaping mode is different; different The shaping pattern of can also correspond to different precoding matrix groups, and the mapping relationship between one precoding unit in the characterized time-frequency resource and the precoding matrix in the precoding matrix group corresponding to the shaping pattern is different.

例如,網路側(如基地台)對時頻資源進行動態劃分,並通過半靜態信號或動態信號將所劃分的時頻資源包括的預編碼單元的個數I通知給終端。 For example, the network side (such as a base station) dynamically divides time-frequency resources, and notifies the terminal of the number I of precoding units included in the divided time-frequency resources through a semi-static signal or a dynamic signal.
又如,不同子訊框對應不同的個數I,可以根據時頻資源所在的子訊框,確定出該時頻資源中包括的預編碼單元的個數I。 For another example, different subframes correspond to different numbers I, and the number I of precoding units included in the time-frequency resource can be determined according to the subframe where the time-frequency resource is located.
可選的,該至少一個時頻資源的位置可以為預先約定的、或者通過半靜態信號或動態信號獲取到的;或者需要根據賦形模式進行賦形的時頻資源的位置與系統參數之間存在設定的對應關係。 Optionally, the position of the at least one time-frequency resource may be pre-agreed, or obtained through a semi-static signal or a dynamic signal; or between the position of the time-frequency resource that needs to be shaped according to the shaping mode and the system parameters There is a set correspondence.

又如,預先設定子訊框0對應的時頻資源需要根據賦形模式進行賦形,或者預先設定載波1對應的時頻資源需要根據賦形模式進行賦形,等等。 For another example, presetting the time-frequency resources corresponding to subframe 0 needs to be shaped according to the shaping mode, or presetting the time-frequency resources corresponding to carrier 1 needs to be shaped according to the shaping mode, and so on.

In this embodiment of the present invention, one time-frequency resource is divided into 1 precoding unit, and different precoding units in the time-frequency resource are shaped using different precoding matrices, that is, multiple different ones are used in one time-frequency resource. The precoding matrix is shaped, and the channel is averaged by multiple precoding matrices, even if the channel changes in the time domain, because the CQI is measured by the terminal traversing different precoding matrices, the CQI can still be more accurate Reflecting the actual status of the channel, in high-speed scenarios or other channel-instability scenarios, the effect of feedback time delay is very small, improving system robustness.
