Description

一种信道状态信息的发送方法及终端 A channel state information transmission method and a terminal

技术领域 FIELD

[0001] 本发明涉及移动无线通信领域,特别是涉及一种信道状态信息的发送方法及终端。 [0001] The present invention relates to the field of mobile radio communications, particularly to a method and terminal for transmitting the channel state information.

背景技术 Background technique

[0002] 在长期演进系统(Long Term Evolution,简称为LTE)中,上行需要传输的控制信令有正确/错误应答消息(Acknowledgement/NegativeAcknowledgement,简称为ACK/ NACK),以及反映下行物理信道状态的信道状态信息(Channel State Information,简称为CSI)<XSI主要有以下三种形式:信道质量指示(Channels Quality Indication,简称为CQI)、预编码矩阵指示(Pre-coding Matrix Indicator,简称为PMI),和秩指示(Rank Indicator,简称为RI)。 [0002] In the LTE system (Long Term Evolution, abbreviated as LTE), the control signaling uplink needs to be transmitted to the correct / error response message (Acknowledgement / NegativeAcknowledgement, simply referred to as ACK / NACK), and reflects the downlink physical channel status channel state information (channel state information, referred to as CSI) <XSI are the following three forms: a channel quality indication (channels quality indication, referred to as CQI), precoding matrix indicator (pre-coding matrix Indicator, abbreviated as PMI), and rank indication (rank Indicator, abbreviated as RI).

[0003] LTE系统中,ACK/NACK应答消息是在物理上行控制信道(PhysicalUplink Control,简称为PUCCH)上以格式l/la/lb(PUCCH formatl/lal/b)传输。 [0003] LTE system, ACK / NACK is a response message on a physical uplink control channel (PhysicalUplink Control, abbreviated to PUCCH) (PUCCH formatl / lal / b) transport format l / la / lb. 如果终端(User Equipment,简称为UE)需要发送上行数据,则在物理上行共享信道(Physical Uplink Shared Channel,简称为PUSCH)上传输。 If the terminal (User Equipment, abbreviated as UE) needs to transmit uplink data, the physical uplink shared channel (Physical Uplink Shared Channel, referred to as PUSCH) transmission on. 上报的CSI可以是周期性的,也可以是非周期性的。 The reported CSI may be periodic, may be aperiodic. CSI的具体反馈方式如下表1所示: Specific CSI feedback scheme as shown in Table 1:

[0004] 表1周期性和非周期性上报时对应的上行物理信道 [0004] Table 1 and the corresponding periodic reporting aperiodic uplink physical channel

Figure CN102075293BD00051

[0006] 如表1中所示,如果UE不需要发送上行数据,则周期上报的CSI在PUCCH上以格式2/ 2a/2b(PUCCH format2/2a/2b)传输。 [0006] As shown in Table 1, if the UE does not need to send uplink data, then the period reported CSI on PUCCH (PUCCH format2 / 2a / 2b) in the transmission format 2 / 2a / 2b. UE需要发送上行数据时,则周期上报的CSI在PUSCH上传输;非周期性上报的CSI只在PUSCH上传输。 When the UE needs to send uplink data, then the period reported CSI transmission on the PUSCH; aperiodic reported CSI transmitted only on the PUSCH.

[0007] 上行控制信令在PUSCH上传输的示意图如图1所示。 [0007] The schematic uplink control signaling transmitted on the PUSCH shown in Fig. 基站通过上行调度授权(Uplink grant,简称为UL grant)信令调度某个UE发送PUSCH。 Signaling a base station scheduling PUSCH, the UE transmits an uplink scheduling grant (Uplink grant, simply referred to as UL grant). 上行调度授权信令可由具有下行控制信息(Downlink Control Information,简称为DCI)格式0(DCI format 0)的物理下行控制信道(Physical Downlink ControlChannel,简称为FOCCH)发送给所调度的UE。 Uplink scheduling grant signaling may have a physical downlink control channel downlink control information (Downlink Control Information, abbreviated to DCI) format 0 (DCI format 0) a (Physical Downlink ControlChannel, abbreviated as FOCCH) transmitted to the scheduled UE. 其中,DCI format 0中有1比特用于触发非周期CSI上报,如果UE检测到属于它的具有DCI format 0格式的ΗΧΧΗ,则根据其中包含的UL grant发送PUSCH。 Wherein, in DCI format 0 and 1 bits for triggering an aperiodic CSI is reported, if the UE detects ΗΧΧΗ with DCI format 0 format belonging to it, according to the UL grant transmitted PUSCH contained therein. 如果UE检测到DCI format 0中的触发非周期CSI上报的1比特置为'1',则在该DCI formatO所调度的PUSCH中发送非周期CSI报告。 If the UE detects triggering an aperiodic DCI format 0 in the CSI reported by 1 bit to '1', then send the aperiodic CSI reporting DCI formatO scheduled PUSCH.

[0008] CSI (包括周期CSI和非周期CSI)在PUSCH上传输时的编码过程主要包括:首先,计算所需的编码调制符号个数,qr/ ;然后,进行信道编码,速率匹配,直到满足目标长度Qcqi = Qcq/ ,Qri = Qr/抑为止。 [0008] CSI (CSI including periodic and non-periodic CSI) encoding process when the transmission on the PUSCH including: First, the number of required calculations coded modulation symbols, qr /; Then, channel coding, rate matching, until meeting target length Qcqi = Qcq /, Qri = Qr / suppression so far. 其中Qm是PUSCH对应传输块的调制阶数;再将编码后的CSI 信息、编码后的数据和/或其他编码后的上行控制信息进行信道交织后传输。 Where Qm is the modulation order corresponding to the PUSCH transport block; the CSI information is then encoded, and the encoded data or the uplink / other coding control information transmission after the channel interleaving.

[0009] 为了满足高级国际电信联盟(Internat ional Te 1 ecommunicat ionUnion-Advanced,简称为ITU-Advanced)的要求,作为LTE演进标准的高级长期演进(Long Term Evolution Advanced,简称为LTE-A)系统需要支持更大的系统带宽(最高可达100MHz),并需要后向兼容LTE现有的标准。 [0009] In order to meet the advanced ITU (Internat ional Te 1 ecommunicat ionUnion-Advanced, referred to as ITU-Advanced) request LTE long term evolution advanced as a standard evolution (Long Term Evolution Advanced, referred to as LTE-A) system requires support for larger system bandwidth (up to 100MHz), and the need for LTE compatible to existing standards. 在现有LTE系统的基础上,可以通过将LTE系统的带宽进行合并来获得更大的带宽,这种技术称为载波聚合(Carrier Aggregation,简称为CA)技术。 In the existing LTE system, may be performed by the combined bandwidth of the LTE system to obtain greater bandwidth, this technique is called carrier aggregation (Carrier Aggregation, simply referred to as CA) technology. CA 技术能够提高IMT-Advance系统的频谱利用率、缓解频谱资源紧缺,进而优化频谱资源的利用。 CA technology can improve the spectrum efficiency IMT-Advance system, ease the shortage of spectrum resources, thus optimizing the use of spectrum resources. 载波聚合的LTE系统带宽可以看作分量载频(Component Carrier,简称为频谱),每个分量载频也可以称为一个小区(Cell),也就是说一个频谱可以由η个分量载频聚合而成。 Carrier aggregation LTE system bandwidth can be regarded as the carrier frequency component (Component Carrier, referred to as the spectrum), each of the component carriers may also be called a cell (the Cell), that is to say of a spectrum may η polymerization of component carrier to make. 一个R10UE的资源由频域的η个小区(或分量载频)构成,其中,一个小区称为主小区或主分量载波(Primary cell),其余小区称为辅小区或辅分量载波(Secondarycell) 〇 R10UE a resource (or carrier frequency component) from the frequency domain plots η configuration, wherein the primary cell or a cell called a primary component carrier (Primary cell), referred to as a secondary cell or cell remaining secondary component carrier (Secondarycell) square

[0010] 目前,关于载波聚合场景下非周期csi上报的结论是: [0010] Currently, the carrier aggregation scenario on aperiodic reporting csi concluded that:

[0011] A,如果是基于用户搜索空间,UL grant里有2比特用来触发非周期CSI上报:其中, "〇〇"代表没有触发非周期CSI上报;"01"代表触发和上行小区SIB-2(第二类系统信息块)相连的下行小区(或分量载波)的非周期CSI上报;"10"通过RRC信令配置触发哪些下行小区(或分量载波)的非周期CSI上报;"11"通过RRC信令配置触发哪些下行小区(或分量载波)的非周期CSI上报; [0011] A, is based on the user if the search space, UL grant, there are two bits for triggering an aperiodic CSI is reported: wherein, "took office" stands for not triggering an aperiodic CSI is reported; "01" represents an uplink cell and trigger SIB- 2 (second type of system information blocks) coupled to a downlink cell (or component carrier) aperiodic CSI is reported; which trigger a downlink cell (or component carrier) aperiodic CSI is reported "10" configured by RRC signaling; "11" What downlink cell (or component carrier) configured by RRC signaling triggered aperiodic CSI is reported;

[0012] B,如果是基于公共搜索空间,则UL grant里有1比特用来触发非周期CSI上报,其中'〇'代表没有触发非周期CSI上报,'1'代表触发非周期CSI上报,但是触发哪个下行小区(或分量载波)的非周期CSI上报还需要进一步讨论,触发的一个或多个下行小区(或分量载波)的非周期CSI上报在UL grant对应的PUSCH上传输。 [0012] B, if it is based on the common search space, there is a 1-bit UL grant for aperiodic CSI reporting is triggered, wherein the 'square' represents not triggering aperiodic CSI is reported, '1' for triggering an aperiodic CSI is reported, but which downlink cell (or component carrier) triggering aperiodic CSI reporting required further discussion, triggering one or more downlink cells (or component carrier) aperiodic CSI reporting on PUSCH transmission corresponding UL grant.

[0013] 对于周期CSI上报的结论是:每一个下行小区(或分量载波)上报时所需的参数是独立配置的,当没有触发非周期CSI上报且主小区(或分量载波)上有PUSCH传输时,周期CSI 上报在主小区(或分量载波)上的PUSCH传输;当主小区(或分量载波)上没有PUSCH传输时, 在其他上行小区(或分量载波)的PUSCH上传输,具体选择哪个小区(或分量载波)还需要进一步讨论。 [0013] For periodic reporting CSI conclusion: required for each downlink cell (or component carrier) reporting parameter is configured independently, aperiodic triggered when no CSI is reported and there is a main cell (or component carrier) transmission of the PUSCH when, periodic CSI reporting PUSCH transmission on the primary cell (or component carrier); and when there is no PUSCH transmission on the primary cell (or component carrier), the transmission on PUSCH other uplink cells (or component carrier), which cell specific selection ( or component carrier) require further discussion.

[0014] 综上所述,现有技术中存在如下技术问题:在LTE-A载波聚合场景下,存在多个下行小区(或分量载波)的CSI在PUSCH上发送的场景,但是目前尚未提出多个小区(或分量载波)的CSI上报时,如何在PUSCH上发送的方案,从而无法实现载波聚合下CSI信息在PUSCH上的传输。 [0014] In summary, the following technical problems in the prior art: In the LTE-A carrier aggregation scenario, the presence of a plurality of scene cells downlink (or component carrier) is transmitted on the PUSCH CSI, but has not yet been proposed a multi- when a cell (or component carrier) CSI is reported how the program transmitted on the PUSCH, and thus can not be achieved under the carrier aggregation information is transmitted on a PUSCH CSI.
