Description

一种信道状态信息的传输方法和设备 A channel state information transmission method and apparatus

技术领域 FIELD

[0001] 本发明涉及无线通信领域,尤其涉及一种信道状态信息的传输方法和设备。 [0001] The present invention relates to wireless communications, and in particular relates to a method and apparatus for transmitting channel state information.

背景技术 Background technique

[0002] LTE-A (Long Term Evolution-Advanced,长期演进技术的后续演进)采用同频组网,在大幅度提高频谱利用率的同时,也会造成小区边缘的用户信号衰落严重,同时还会受到较高的来自其他小区的干扰,若不对信号衰落和干扰问题加以处理,将会严重影响边缘用户的体验。 [0002] LTE-A (Long Term Evolution-Advanced, the subsequent evolution of LTE) network using the same frequency, at the same time greatly improve the spectrum utilization, user can also cause severe signal fading cell edge, while also subject to higher interference from other cells, if not processed signal fading and interference problems will seriously affect the edge user experience. 多点协作(Coordinated Multiple Point,CoMP)技术通过引入多小区之间的信息交互和联合传输,不仅可以提高信号质量也可以降低小区间干扰,从而可以大幅度提高小区边缘用户的数据传输性能。 Coordinated multi-point (Coordinated Multiple Point, CoMP) by introducing a technique and information exchange between the multi-cell joint transmission, not only can improve the signal quality may be reduced inter-cell interference, which can greatly improve the data transfer performance of the cell edge users.

[0003]目前的多点协作传输方案大致包括:动态传输点选择(Dynamic PointSelection, DPS),协作波束赋形(Coordinated Beamforming, CBF)和联合传输(JointTransmission,JT),也可以是以上3类传输方案的混合方案。 [0003] It coordinated multi-point transmission schemes generally include: dynamic transmission point selection (Dynamic PointSelection, DPS), cooperative beamforming (Coordinated Beamforming, CBF) and joint transmission (JointTransmission, JT), or may be three or more Class Transmission hybrid solution scheme. 比如,DPS和CBF相结合,主传输点通过动态选择确定,与非主传输点外的协作传输点之间通过联合调度实现协作波束赋形等。 For example, DPS and CBF combination, the main transmission point determined by the dynamic selection, to achieve cooperative beamforming and the like between the outer joint scheduling transmission point non-primary cooperative transmission point. 在实际系统中,一个传输模式可能包括多种传输方案,支持各类传输方案之间的模式切换。 In a practical system, a transmission mode may include a plurality of transmission schemes, various types of transmission between the support mode switching scheme. 为了更好地保证传输性能和系统稳定性,支持CoMP传输的传输模式中往往需要支持向单点传输的切换。 In order to better ensure the transmission performance and system stability, to support CoMP transmission often requires support transmission mode is switched to single-point transmission.

[0004]系统通过配置不同的 CS1-RS (Channel State Information Reference Signal,信道状态信息参考信号)使得用户设备(User EqUipment,UE)可以测量各个“传输点”的下行信道。 [0004] system by configuring different CS1-RS (Channel State Information Reference Signal, a channel state information reference signal) so that the user equipment (User EqUipment, UE) can measure the respective "transmission point" downlink channel. 值得注意的是,“传输点”可能并非一个物理的传输点,而可能是一个虚拟的传输点,每个虚拟传输点对应于一个CS1-RS资源,由一个或多个物理的传输点构成。 Notably, "transmission point" may not be a physical transmission point, but may be a virtual transmission point, each virtual transmission point corresponds to a CS1-RS resource composed of one or more physical transmission point.

[0005] 实现下行信道测量后,根据传输方案所需要的信道状态信息进行信息反馈。 [0005] After achieve downlink channel measurement, a feedback information transmission scheme according to the channel state information needed. 各类传输方案需要相应的信道状态信息支持。 Various types of transmission scheme requires the channel state information corresponding support. 比如,DPS需要多个传输点的信道状态信息,或者某一个传输点的信道状态信息和该传输点所对应的CS1-RS索引信息。 For example, DPS requires more transmission points CS1-RS channel state information indexed channel state information and the transmission point information, or the one corresponding to the transmission point. CBF和非相关JT需要主传输点的RI不受限的信道状态信息和非主传输点的RI=I的信道状态信息。 RI channel state information and the non-transmission point of the main channel and non-related CBF JT primary transmission point need not be limited RI = I channel state information. 相关JT需要主传输点的RI不受限的信道状态信息,各传输点的RI=I的信道状态信息,以及各传输点的相对相位信息。 JT needs related primary transmission point RI is not limited channel state information, each transmission point RI = I channel state information, and the relative phase information of each transmission point. 所谓主传输点即DPS和CBF中给UE传输数据的传输点,或者JT若回退到单点传输时给UE传输数据的传输点。 The so-called primary transmission point and the transmission point i.e. DPS CBF data are transmitted to the UE, to the UE or JT transmission points transmit data fall back to a single point if the transmission.

[0006] 实际实现时,可以通过分级反馈的方式实现通用反馈,即对测量集合(测量集合是网络为UE配置的一个传输点集合,UE需要观测测量集合内的传输点的信道状态信息,并实现反馈)内的每个传输点反馈单点的信道状态信息,再分别反馈传输点之间的相位信息和/或幅度信息。 [0006] The actual implementation may be achieved by way of hierarchical feedback common feedback, i.e. on measurement set (measurement set is a transmission point network configuration for the UE set, UE needs to observe the channel state information transmission point in the measurement set, and channel state information feedback to achieve single point for each feedback transmission point) within, and then fed back phase information and / or amplitude information between the transmission point. 网络基于这两部分信息合成对测量集合内的传输点到UE的信道状态信息。 Network information based on the channel state information of the two parts of the transmission point in the synthesis of measurement set to the UE. 以测量集合包含两个传输点为例,两个传输点UE的信道分别记为H1和H2, UE为两个传输点分别选择预编码矩阵W1和W2 (这里的预编码矩阵即为信道状态信息),则两个小区间的相位和幅度信息可以按如下的方式选取:[0007] In measurement set comprises two transmission points, for example, channel two transmission points are referred to as UE H1 and H2 of, respectively UE select a precoding matrix W1 and W2 (where pre-coding matrix is ​​the channel state information of two transmission points ), the cells between the two phase and amplitude information may be selected in the following manner: [0007]

Figure CN102237968BD00091

[0008] 其中g属于预先定义的码本集合。 [0008] wherein g belonging to a set of predefined codebooks. 如果W1和W2的列数记为M,则g为MXM的对角矩阵,M=I则g退化为一个标量。 If the sequence of W1 and W2 is denoted M, the MXM g is a diagonal matrix, M = I then degenerates to a scalar g. 如果g是标量,则其码本集合A可以是16QAM星座图中的点: If g is a scalar, then it may be a codebook set A 16QAM constellation points:

[0010] 也可以是QPSK星座图中的点: [0010] may be a QPSK constellation point:

[0011 ] [0011]

Figure CN102237968BD00093

[0012] 上述方案中,UE在反馈时对所有的传输点是同等对待的。 [0012] In the above embodiment, UE feedback when all the transmission points are treated equally. 而实际上,这些传输点的在各种方案中的作用并不相同。 In fact, the role of these points in various transmission schemes are not the same. 在协作调度/波束赋形和动态传输点选择方案中,只有I个点会向UE发送数据,这个传输点的信道信息的精度要求会高于其他的传输点,且该传输点应该可以支持空间复用传输(即允许RANK>1)。 In the coordinated scheduling / beamforming and dynamic transmission point selection scheme, only I points send data to the UE, the accuracy of channel information transmission point required will be higher than other transmission points and the transmission point should be able to support the space complex (i.e., allowing RANK> 1) by a transmission. 动态传输点选择方案实际上只需要I个传输点的信道状态信息,为了支持其他的方案,其他传输点的信息也需反馈,但是对动态传输点选择方案的并没有什么意义。 Dynamic transmission point selection scheme actually need only point I transmission channel state information, in order to support other programs, other information transmission points also need feedback, but the dynamic transmission point selection scheme does not make sense. JT案支持高RANK传输并不会带来明显的性能提升,但是会给反馈带来很高的复杂度,因此支持JT方案的反馈只需要各个传输点的RANKl的信道状态信息。 JT RANK support high transmission case and will not bring significant performance gains, but will give feedback to bring a high degree of complexity, and therefore support the JT scheme only feedback channel state information needs RANKl each transmission point.

[0013] 在现有的长期演进(Long-Term Evolution, LTE)系统中,支持两类信道状态信息反馈方式,即基于物理上行控制信道(Physical Uplink Control Channel, PUCCH)的周期反馈和基于物理上行共享信道(Physical Uplink Shared Channel, PUSCH)的非周期信道状态信息反馈。 [0013] In the conventional long term evolution (Long-Term Evolution, LTE) system supports two types of channel state information feedback scheme, i.e., based on the physical uplink control channel (Physical Uplink Control Channel, PUCCH) based on the periodic physical uplink feedback and shared channel (Physical Uplink shared channel, PUSCH) aperiodic channel state information feedback. 基于PUCCH的周期反馈包括4类反馈模式(Reporting Mode),模式1-0,2-0,1-1和2-1。 The PUCCH-based periodic feedback mode feedback includes 4 classes (Reporting Mode), 1-0,2-0,1-1 and 2-1 pattern. 各类反馈模式一共包换l、la、2、2a、2b、2c、3、4、5、6共10种报告类型(Reporting Type)。 Total replacement of various types of feedback mode l, la, 2,2a, 2b, 2c, 3,4,5,6 reported a total of 10 types (Reporting Type). 其中模式1_0和2-0支持不包含PMI反馈的信道状态信息反馈,可以用于TDD (Time Division Duplexing,时分双工)系统中多输入多输出(Multiple-1nputMultiple-Output, ΜΙΜΟ)传输。 2-0 and wherein the support 1_0 mode channel state information does not include PMI feedback, can be used to TDD (Time Division Duplexing, time division duplex) system, a MIMO (Multiple-1nputMultiple-Output, ΜΙΜΟ) transmission. 表I 不出了PUCCH CSI 反馈模式的CQI (Channel QualityIndicator,信道质量指示)和PMI反馈类型,表2示出了每个PUCCH反馈模式和模式状态的PUCCH报告类型负荷大小。 Table I not the feedback mode, CQI PUCCH CSI (Channel QualityIndicator, channel quality indication) and PMI feedback types, Table 2 shows the size of each load PUCCH reporting type PUCCH feedback mode and the mode status.

具体实施方式 Detailed ways

[0062] 需要注意的是,在TDD系统中,eNB (evolved NodeB,演进节点B,即基站)可以通过上行探测导频(Sounding Reference Signal, SRS)信道估计值,借助信道互易性获得部分或全部下行信道的空间特性。 [0062] Note that, in a TDD system, eNB (evolved NodeB, an evolved Node B, i.e. base station) may frequency (Sounding Reference Signal, SRS) the channel estimation value, by means of a channel through an uplink sounding pilot reciprocity obtain partial or all downlink spatial characteristics of the channel. 比如,若传输点内各天线实现了较好的上下行互易校准,就可以不反馈各传输点的预编码矩阵索引(Precoding Matrix Indicator, PMI)信息,若传输点间各天线实现了较好的上下行互易校准,也可以不反馈传输点间的相对相位信息了。 For example, if the transmission point of each antenna to achieve a better downlink reciprocity calibration, it may not be feedback precoding matrix index (Precoding Matrix Indicator, PMI) information of each transmission point, when the transmission point between each of the antenna to achieve a better reciprocity calibration uplink and downlink, the feedback may not be the relative phase information between a transmission point. 进一步地,即便在FDD (Frequency Division Duplexing,频分双工)系统中,上下行信道的长期、宽带信道状态信息也存在一定的互易关系,在某些情况下也可以不反馈各传输点的宽带/长期PMI信息。 Further, even in the FDD (Frequency Division Duplexing, FDD) system, long uplink and downlink channels of the wideband channel state information, there are some reciprocity relation, and in some cases may not be feedback each transmission point broadband / long-term PMI information.
