Description

一种上报信道状态信息的方法及设备Method and device for reporting channel state information 技术领域Technical field
本发明涉及移动通信技术领域,尤其涉及一种上报信道状态信息的方法及设备。The present invention relates to the field of mobile communications technologies, and in particular, to a method and a device for reporting channel state information.
背景技术Background technique
在LTE(Long Term Evolution,长期演进)系统中,如图1所示,网络侧设备(比如基站)通常会下发信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS),而终端设备在接收到所述CSI-RS参考符号后,将根据该CSI-RS参考符号估计下行信道的信道状态信息(Channel State Information,CSI),并上报计算出的CSI至网络侧设备,以便网络侧设备为终端设备进行资源调度以及进行预编码。In the LTE (Long Term Evolution) system, as shown in FIG. 1 , a network side device (such as a base station) usually sends a channel state information reference signal (CSI-RS), and the terminal device After receiving the CSI-RS reference symbol, the channel state information (CSI) of the downlink channel is estimated according to the CSI-RS reference symbol, and the calculated CSI is reported to the network side device, so that the network side device Resource scheduling and precoding for the terminal device.
目前,在多输入多输出(Multiple Input and Multiple Output,MIMO)的LTE系统中,终端设备所上报的CSI中至少包括宽带信道质量索引(Channel Quality Index,CQI)、预编码矩阵索引(Precoding Matrix Index,PMI)以及秩索引(Rank Index,RI);其中,宽带CQI用于向网络侧设备上报当前下行信道传输数据的信道质量,以便于网络侧设备为终端设备进行资源调度和确定调制编码方式,而RI用于向网络侧设备上报在一资源块上可同时传输的数据的层数,比如当RI=2时,表示下行链路可以支持在一资源块上同时传输2层数据;而在MIMO系统中,网络侧设备在发送数据前,通常对待发送数据进行预编码,将该数据映射为多个子数据,然后将这多个子数据通过不同的天线端口发射出去,而终端设备在接收到上述数据时,通过对接收到的数据进行空时译码,即可恢复出原来的数据;而所述PMI用于所述终端设备向网络侧设备上报所述终端测量得到的预编码的矩阵,所述预编码矩阵用于将下行数据映射为多个子数据;其中,上述预编码矩阵W,通常由两级组成,分别为W1和W2,即W=W1×W2,因此,相应的,在CSI中PMI也具体由PMI1和宽带PMI2组成,且PMI1与W1相对应,宽带PMI2与W2相对应。At present, in the MIMO system of the multiple input and multiple output (MIMO), the CSI reported by the terminal device includes at least a wideband channel quality index (CQI) and a precoding matrix index (Precoding Matrix Index). (PMI) and a Rank Index (RI); wherein the wideband CQI is used to report the channel quality of the current downlink channel transmission data to the network side device, so that the network side device performs resource scheduling and determines a modulation and coding mode for the terminal device. The RI is used to report the number of layers of data that can be simultaneously transmitted on a resource block to the network side device. For example, when RI=2, it indicates that the downlink can support simultaneous transmission of Layer 2 data on one resource block; In the system, before sending data, the network side device usually pre-codes the data to be transmitted, maps the data into multiple sub-data, and then transmits the multiple sub-data through different antenna ports, and the terminal device receives the data. At the time, the original data can be recovered by performing space-time decoding on the received data; and the PMI is used for the And the pre-coding matrix is used to map the downlink data to the plurality of sub-data, where the pre-coding matrix W is usually composed of two levels, respectively W1 and W2, that is, W=W 1 ×W 2 , therefore, correspondingly, in the CSI, the PMI is also specifically composed of PMI1 and wideband PMI2, and PMI1 corresponds to W1, and broadband PMI2 corresponds to W2.
在现有技术中,定义了若干种周期上报PMI的上报模式。图2所示其中之一周期上报PMI的模式。终端设备上报CSI的过程具体如下:将R1和PMI1进行联合编码进行第一级上报,然后将宽带PMI2和宽带CQI进行联合编码进行第二级上报;其中,上述两级上报均采用第2格式的PUCCH(即PUCCH format2)、第2a格式的PUCCH信道(即PUCCH format2a)或第2b格式的PUCCH信道(即PUCCH format2b)承载,而在一次上报过程中,PUCCH format2/2a/2b信道最多只能承载13比特的CSI数据;而随着在LTE Rel14中CSI增强技术的应用,PMI1和宽带PMI2所占用的数据量可能会出现大于13比特的需求,那么在现有技术中仅采用PUCCH format2/2a/2b信道上报CSI显示不能满足需求。In the prior art, several reporting modes for periodically reporting PMI are defined. One of the cycles shown in Figure 2 reports the PMI mode. The process of reporting the CSI by the terminal device is as follows: the R1 and the PMI1 are jointly coded for the first level reporting, and then the broadband PMI2 and the broadband CQI are jointly coded for the second level reporting; wherein the two levels of reporting are in the second format. The PUCCH (that is, the PUCCH format 2), the PUCCH channel of the 2a format (ie, the PUCCH format 2a) or the PUCCH channel of the 2b format (that is, the PUCCH format 2b) are carried, and in a single reporting process, the PUCCH format 2/2a/2b channel can only carry at most 13-bit CSI data; with the application of CSI enhancement technology in LTE Rel14, the amount of data occupied by PMI1 and wideband PMI2 may exceed the requirement of 13 bits, then only PUCCH format2/2a/ is used in the prior art. The 2b channel reporting CSI display does not meet the demand.

具体实施方式detailed description
下面将结合本发明实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述。The technical solutions in the embodiments of the present application will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments.
本申请提供一种上报信道状态信息的方法及设备,首先介绍一下本申请的应用场景:The present application provides a method and device for reporting channel state information. First, the application scenario of the present application is introduced:
在LTE(Long Term Evolution,长期演进)系统中,如图1所示,网络侧设备(比如 基站)通常会下发信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS),而终端设备在接收到所述CSI-RS参考符号后,将根据该CSI-RS参考符号估计下行信道的CSI,并上报计算出的CSI至网络侧设备,以便网络侧设备为终端设备进行资源调度以及进行预编码。In the LTE (Long Term Evolution) system, as shown in Figure 1, the network side device (such as The base station) usually sends a channel state information reference signal (CSI-RS), and after receiving the CSI-RS reference symbol, the terminal device estimates the downlink channel according to the CSI-RS reference symbol. The CSI is used to report the calculated CSI to the network side device, so that the network side device performs resource scheduling and precoding for the terminal device.
目前,在多输入多输出(Multiple Input and Multiple Output,MIMO)的LTE系统中,终端所上报的CSI中至少包括宽带信道质量索引(Channel Quality Index,CQI)、预编码矩阵索引(Precoding Matrix Index,PMI)以及秩索引(Rank Index,RI);其中,宽带CQI指示当前下行信道传输数据的信道质量,以便于网络侧设备根据所上报的CQI为终端设备确定资源调度和调制编码方式,而RI用于终端设备向网络侧设备指示在一资源块上可同时传输数据的层数,比如当RI=2时,表示在一资源块上可同时传输2层数据;而在MIMO系统中,网络侧设备在发送数据前,通常对待发送数据进行预编码,将该数据映射为多个子数据,然后将这多个子数据通过不同的天线端口发射出去,而终端设备在接收到上述数据时,通过对接收到的数据进行空时译码,即可恢复出原来的数据;而所述PMI用于,网络侧设备确定对待传输数据进行预编码的矩阵,以将待传输数据映射为多个子数据;其中,上述预编码矩阵W,通常由两级组成,分别为W1和W2,即W=W1×W2,因此,相应的,在CSI中PMI也具体由PMI1和PMI2组成,且PMI1用于指示W1,PMI2用于指示W2。At present, in the LTE system of the multiple input and multiple output (MIMO), the CSI reported by the terminal includes at least a wideband channel quality index (CQI) and a precoding matrix index (Precoding Matrix Index, PMI) and a Rank Index (RI); wherein the wideband CQI indicates the channel quality of the current downlink channel transmission data, so that the network side device determines the resource scheduling and modulation and coding mode for the terminal device according to the reported CQI, and the RI uses The terminal device indicates to the network side device the number of layers that can simultaneously transmit data on a resource block, for example, when RI=2, it means that two layers of data can be simultaneously transmitted on one resource block; and in the MIMO system, the network side device Before sending data, the data to be sent is generally precoded, the data is mapped into a plurality of sub-data, and then the plurality of sub-data are transmitted through different antenna ports, and the terminal device receives the data by receiving the data. The data is free-time decoded, and the original data can be recovered; and the PMI is used, and the network-side device determines to process the data. Data precoding matrix to the data to be transmitted is mapped to a plurality of sub-data; wherein, the pre-coding matrix W, usually consists of two stages, respectively as W1 and W2 of, i.e., W = W 1 × W 2, and therefore, the respective In the CSI, the PMI is also specifically composed of PMI1 and PMI2, and PMI1 is used to indicate W1, and PMI2 is used to indicate W2.
在现有技术中,一般采用物理上行链路控制信道(Physical Uplink Control CHannel,PUCCH)的格式2/2a/2b上报所述CSI,其中格式2a/2b用于CSI和用于指示下行数据是否正确接收的指示信息(Acknowledgement,简称ACK)一起上报,其中ACK调制到上行参考符号上,不占用CSI资源,即ACK信息不影响CSI的调制、编码和数据映射方式,为了描述简单,下面将格式2/2a/2b统称为格式2(PUCCH format2)。在一次上报过程中,所述PUCCH format2最多仅能承载11比特的CSI数据;但随着在LTE Rel14中CSI增强技术的应用,PMI1和PMI2所占用的比特数可能会出现大于11比特的需求,那么在现有技术中仅采用PUCCH format2上报CSI显示不能满足需求。In the prior art, the CSI is generally reported in the format 2/2a/2b of the Physical Uplink Control CHannel (PUCCH), where the format 2a/2b is used for CSI and is used to indicate whether the downlink data is correct. The received indication information (Acknowledgement, ACK for short) is reported together, wherein the ACK is modulated onto the uplink reference symbol, and the CSI resource is not occupied, that is, the ACK information does not affect the modulation, coding, and data mapping modes of the CSI. For the sake of simplicity, the following format 2 /2a/2b is collectively referred to as format 2 (PUCCH format 2). In a single reporting process, the PUCCH format 2 can only carry up to 11 bits of CSI data; however, with the application of CSI enhancement technology in LTE Rel14, the number of bits occupied by PMI1 and PMI2 may exceed the requirement of 11 bits. Then, in the prior art, only the PUCCH format 2 reporting CSI display cannot meet the requirement.
基于上述应用场景,本申请提供了一种上报CSI的方法,所述CSI包括第一CSI和第二CSI,如图3所示,所述方法如下:Based on the foregoing application scenario, the present application provides a method for reporting CSI, where the CSI includes a first CSI and a second CSI, as shown in FIG. 3, and the method is as follows:

步骤S37:网络侧设备根据所接收的第一CSI和第二CSI,对终端设备进行资源调度和预编码。Step S37: The network side device performs resource scheduling and precoding on the terminal device according to the received first CSI and the second CSI.
需要说明的是,在本申请实施例中,网络侧设备可根据当前网络的配置情况,确定终端设备上报第一CSI时所采用的第一格式的PUCCH,以及上报第二CSI时所采用的第二格式的PUCCH,最后,将第一格式的PUCCH和第二格式的PUCCH配置在终端设备中,而终端设备将在第一时刻采用第一格式的PUCCH上报第一CSI,在第二时刻采用第二格式的PUCCH上报第二CSI。It should be noted that, in the embodiment of the present application, the network side device may determine, according to the current network configuration, the PUCCH of the first format used by the terminal device to report the first CSI, and the first adopted when reporting the second CSI.

The second CSI is reported in the second-level reporting process, and the PUCCH in the second format is also capable of carrying the second CSI; since the PUCCH used in each level reporting process can carry the reported CSI, then In the manner disclosed in the embodiment of the present application, the PUCCH used for reporting the PMI1 and the PMI2 in the CSI enhancement technology (PMI1 and PMI2 are both part of the CSI) are bound to carry the PMI1 and the PMI2, thereby solving the simple in the prior art.

在第一时刻采用PUCCH format2或PUCCH format3上报RI和PMI1;Reporting RI and PMI1 in PUCCH format 2 or PUCCH format 3 at the first moment;
通过上述介绍可知,PUCCH format2最大可承载13比特的数据,而PUCCH format3可承载22比特的数据;而在现有技术中的CSI增强中,RI的上报一般为3比特,而对于PMI1和PMI2的上报所占用的比特与网络侧设备所采用的天线布局相关,具体的PMI1和PMI2上报所占用的比特与天线布局的关系,可参见下表1所示,其中(NTx(A×B)表示双极化天线有N个天线端口,其中所述N个天线端口有A行和B列,其中N=2×A×B);According to the above description, PUCCH format 2 can carry up to 13 bits of data, and PUCCH format 3 can carry 22 bits of data.

表1Table 1
对此,在本申请实施例中,具体提供三种上报RI和PMI1的方式,具体如下:In this regard, in the embodiment of the present application, three manners for reporting RI and PMI1 are specifically provided, as follows:
第一种:对于4Tx和8Tx布局的天线,采用PUCCH format2上报RI和PMI1,而对于16Tx和32Tx的天线,采用用PUCCH format3上报RI和PMI1;The first type: for the antennas of the 4Tx and 8Tx layouts, the RI and PMI1 are reported by the PUCCH format2, and the RI and PMI1 are reported by the PUCCH format3 for the 16Tx and 32Tx antennas;
通过上述表1可以看出,对于4Tx和8Tx布局的天线,其上报PMI1所占用的总比特数小于等于8比特,而上报RI一般占用3比特,因此,其上报PMI1+RI所占用的总数据量小于等于11比特,因此可采用PUCCH format2承载;而对于16Tx和32Tx天线端口的天线,其上报PMI1所占用的总比特数最小为10比特,最大为13比特,因此可见,PMI+RI的上报最少也需占用13比特,最多需占用16比特,此时PUCCH format2难以承载,因要采用承载数据量为22比特的PUCCH format3进行承载。It can be seen from the above Table 1 that for the antennas of the 4Tx and 8Tx layouts, the total number of bits occupied by the reported PMI1 is less than or equal to 8 bits, and the reported RI generally occupies 3 bits. Therefore, the total data occupied by the PMI1+RI is reported. The amount is less than or equal to 11 bits, so the PUCCH format 2 bearer can be used; and for the antennas of the 16Tx and 32Tx antenna ports, the total number of bits occupied by the reported PMI1 is a minimum of 10 bits and a maximum of 13 bits, so it can be seen that the PMI+RI is reported. A minimum of 13 bits is required, and a maximum of 16 bits are occupied. In this case, PUCCH format 2 is difficult to bear, and is carried by PUCCH format 3 carrying 22 bits of data.
第二种:无论何种布局的天线,均采用PUCCH format3上报RI和PMI1;The second type: Regardless of the layout of the antenna, PUCCH format3 is used to report RI and PMI1;
同样,通过上述论述可知,在现有布局的天线中,上报PMI最多需占用13比特的数据量,而上报RI一般占用3比特的数据量,因此,在现有布局的天线中,上报RI+PMI1最多占用16比特的数据,因此,采用承载数据量为22比特的PUCCH format3可以承载RI和PMI1的上报;Similarly, it can be seen from the above discussion that in the antenna of the existing layout, the reported PMI needs to occupy a maximum of 13 bits of data, and the reported RI generally occupies 3 bits of data. Therefore, in the antenna of the existing layout, the RI+ is reported. PMI1 can occupy up to 16 bits of data. Therefore, PUCCH format 3 with a capacity of 22 bits can carry the reporting of RI and PMI1.
第三种:无论何种布局的天线,均采用PUCCH format2上报RI和PMI1;The third type: Regardless of the layout of the antenna, PUCCH format2 is used to report RI and PMI1;
在本实施方式中,对于4Tx和8Tx布局的天线,可直接采用PUCCH format2上报编码 后的RI和PMI1,而对于16Tx和32Tx的天线端口,可首先对上报的PMI1和RI进行下采样,使之占用的比特数小于等于13比特,然后再采用PUCCH format2上报下采样后的PMI1和RI;In this embodiment, for the antennas of the 4Tx and 8Tx layouts, the PUCCH format2 reporting code can be directly used. After the RI and PMI1, for the 16Tx and 32Tx antenna ports, the reported PMI1 and RI can be downsampled first, so that the number of occupied bits is less than or equal to 13 bits, and then the PMI1 and the downsampled PMI1 are reported by the PUCCH format2. RI;
当然,在本申请实施例中,可不区分天线的布局,直接对编码后的RI和PMI1进行下采样,使下采样后的RI和PMI1所占用的总比特数小于13比特,然后直接采用PUCCH format2上报下采样后的RI和PMI1。Certainly, in the embodiment of the present application, the encoded RI and PMI1 may be directly sampled without distinguishing the layout of the antenna, so that the total number of bits occupied by the downsampled RI and PMI1 is less than 13 bits, and then the PUCCH format 2 is directly used. The downsampled RI and PMI1 are reported.
网络侧设备接收RI和PMI1;The network side device receives the RI and the PMI1;
终端设备在第二时刻采用PUCCH format3、PUCCH format4或PUCCH format5上报宽带PMI2和宽带CQI;The terminal device reports the broadband PMI2 and the broadband CQI by using the PUCCH format 3, the PUCCH format 4 or the PUCCH format 5 at the second moment;
在现有技术中,宽带CQI的上报在RANK=2的时候一般需占用7比特的数据量,而通过上述表1可知,宽带PMI2的上报最多仅占用12比特的数据量,可见宽带PMI2+宽带CQI的上报最多仅占用19比特的数据量(19比特=7比特(CQI)+12比特(PMI2)),而通过上述论述可知,,PUCCH format3可承载22比特的数据量,PUCCH format4可承载任意比特的数据量,PUCCH format5可承载大于22比特的数据量,因此,可见,对于宽带PMI2和宽带CQI的上报采用PUCCH format3、PUCCH format4或PUCCH format5均可。In the prior art, the reporting of the wideband CQI generally requires 7 bits of data when RANK=2, and as shown in the above Table 1, the reporting of the wideband PMI2 only occupies at most 12 bits of data, and the broadband PMI2+ wideband CQI can be seen. The report only occupies a maximum of 19 bits of data (19 bits = 7 bits (CQI) + 12 bits (PMI2)). As can be seen from the above discussion, PUCCH format 3 can carry 22 bits of data, and PUCCH format 4 can carry any bit. The amount of data, PUCCH format 5 can carry more than 22 bits of data, so it can be seen that PUCCH format3, PUCCH format4 or PUCCH format5 can be used for reporting of wideband PMI2 and wideband CQI.
网络侧设备接收宽带PMI2和宽带CQI;The network side device receives the broadband PMI2 and the broadband CQI;
网络侧设备根据所接收的RI、PMI1、宽带PMI2以及宽带CQI,对终端设备进行资源调度和预编码。The network side device performs resource scheduling and precoding on the terminal device according to the received RI, PMI1, broadband PMI2, and wideband CQI.

在本申请的一可能实现方式中,上述实施例一中的第一CSI可具体为RI,第一格式的PUCCH可具体为PUCCH format2;第二CSI可具体为宽带CQI、PMI1和宽带PMI2,第二格式的PUCCH可具体为PUCCH format4或PUCCH format5;In a possible implementation manner of the present application, the first CSI in the foregoing Embodiment 1 may be specifically an RI, and the PUCCH in the first format may be specifically a PUCCH format 2; the second CSI may be specifically a broadband CQI, a PMI1, and a broadband PMI2.
