Description

一种信息上报方法及通信装置
本申请要求于2019年01月08日提交中国专利局、申请号为201910015684.5、申请名称为“一种信息上报方法及通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，尤其涉及无线通信系统中的信道质量指示的上报方法及通信装置。
背景技术
信道质量指示(channel quality indication，CQI)是无线信道的通信质量的测量标准，CQI是由用户设备(user equipment，UE)测量所得，基站根据UE上报的CQI确定传输数据块大小，编码方式，调制方式等。
长期演进(long term evolution，LET)协议中，没有明确定义CQI的测量方式，只定义了CQI的选取原则，即保证物理下行共享信道(physical downlink shared channel，PDSCH)的解码错误率(即误块率(block error ratio，BLER))小于10％所使用的CQI。第五代移动通信(the 5th Generation mobile communication，5G)中的三大场景：增强型移动宽带(enhanced mobile broadband，eMBB)、低延时高可靠通信(ultra-reliable low-latency communication，URLLC)、大规模物联网业务(Massive Machine Type Communication，mMTC)。eMBB业务对应的BLER要求小于10 -1，URLLC业务对应的BLER要求小于10 -5。
相对于eMBB业务，由于URLLC业务对BLER要求比较严苛，因此，基站为UE分配资源时，通常会采用较小的码率，使用更多的资源传输数据。当UE较多时，采用较小的码率，则一个UE需要使用更多的资源来传输数据，则在一个调度时间内，能够被调度的UE数目较少，从而导致频谱资源利用率低。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。可以理解的是，所描述的实施例是本申请一部分的实施例，而不是全部的实施例。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(Long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、第五代(5th generation，5G)系统或新无线(new radio，NR)、或者未来演进网络等。
为便于理解本申请实施例，首先结合图1详细说明适用于本申请实施例提供的方法的通信系统。图1中示出了适用于本申请实施例提供的方法的通信系统100的示意图。如图所示，该通信系统100可以包括至少一个网络设备，如图1中所示的5G系统中的基站(gNB)；该通信系统100还可以包括至少一个终端设备，如图1中所示的用户设备(user equipment，UE)1至UE 6。网络设备与终端设备之间可以通过无线链路通信。例如，网络设备可以向终端设备发送配置信息，终端设备可以基于该配置信息向网络设备发送上行数据；又例如，网络设备可以向终端设备发送下行数据。因此，图1中的gNB和UE可以构成一个通信系统。
该通信系统100中的终端设备，如，UE 4至UE 6，也可以构成一个通信系统。例如，UE 4可以控制UE 5和UE 6执行相应的指令。本申请对此不作限定。
应理解，该通信系统中的网络设备可以是任意一种具有无线收发功能的设备。该网络设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband Unit，BBU)，无线保真(wireless fidelity，WiFi)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功 能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+CU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
还应理解，该无线通信系统中的终端设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。
还可以理解，图1仅为便于理解而示例的简化示意图，该通信系统100中还可以包括其他网络设备或者还可以包括其他终端设备，图1中未予以画出。
在通信过程中，CQI用来反映当前信道质量的好坏。例如，可以用0～15来表示PDSCH的信道质量，0表示信道质量最差，15表示信道质量最好。CQI是由UE进行测量所得的。下行数据在传输的过程中，基站(evolved Node Base-station，eNB)需要根据UE上报的CQI，确定传输参数，例如，该传输参数可以包括MCS。例如，UE上报的是10 -1的BLER对应的CQI为10，即CQI索引值为10时，其对应的效率为2.7305，基站可以根据该效率值，从MCS表中找到小于该效率值所对应的MCS索引。例如，该传输参数也可以包括调制方式，该调制方式可以是正交相移键控(quadrature phase shift keying，QPSK)，也可以为16种符号的正交幅度调制(quadrature amplitude modulation，QAM)，也可以是64种符号的QAM，也可以为256种符号的QAM。调制方式的选取，主要取决于BLER的上限值和CQI值。从而基站可以为基站与UE之间的数据传输，从而可以确定传输数据块的大小、编码方式、调制方式等传输参数中的一种或多种。在长期演进(long term evolution，LET)系统中，没有明确定义CQI的测量方式，只定义了CQI的选取准则，该选取原则是根据物理下行共享信道(physical downlink shared channel，PDSCH)的解码错误率(即误块率)小于10％，所使用的CQI。也就是说，UE需要根据测量结果(例如，信号与干扰加噪声比)评估下行链路特性，并采用内部算法确定此SINR条件下所能获取的误块率(block error ratio，BLER)值，并根据BLER<10％的限制，上报对应的CQI。
例如，在5G通信系统中，eMBB业务对应的BLER要求小于10 -1，URLLC业务对应的BLER要求小于10 -5，从而满足URLLC的高可靠性要求，对于URLLC业务，UE上报的CQI的选取原则较严格，因此，基站为UE分配资源时，通常会使用较小的调制与编码 策略(modulation and coding scheme，MCS)，且需要使用更多的资源传输数据。
如前所述，在无线通信系统中，如图1所示的通信系统中，网络设备可以通过终端设备上报的一种BLER对应的CQI或多种BLER对应的CQI，为终端设备分配相应的MCS，从而保证UE获取较好的下行性能。

可以理解的是，在本申请实施例中的多种BLER，可以理解为该多种BLER的上限值不相同。例如，一种BLER的上限值为10 -1(也可以表示成10 -1的BLER)，另一种BLER的上限值为10 -5等(也可以表示成10 -5的BLER)。
可以理解的是，一个CQI表格对应一个调制和编码策略MCS表格，一种BLER可以对应一个或多个CQI表格。例如，如表1、表2、表3所示，其中，表1和表2是BLER的上限值为10 -1时，所对应的CQI表格，表3为10 -5的BLER对应的一个CQI表格。
例如，如表1中所示，效率efficiency为5.5547时，一个资源元素(resource element，RE)能承载的信息为5.554，其余为Turbo冗余比特。例如，使用64QAM的调制方式时，每个RE的信道比特或者说物理比特为6。
可以理解的是，终端设备在给网络设备上报BLER时，一种BLER对应一个CQI进行上报，例如，BLER的上限值为10 -1时，虽然对应两个CQI表格，但是最终上报一个CQI。

下面以终端设备与网络设备之间的交互为例详细说明本申请实施例。可以理解，处于无线通信系统中的一个终端设备可以基于相同的方法与一个或多个网络设备通信。本申请对此不做限定。
图2从设备交互的角度示出本申请实施例提供的一种信道质量指示的上报方法200的示意性流程图。如图所述，该方法可以包括步骤210至步骤230。下面详细说明方法200中的各个步骤。
可选地，步骤210，第二设备(例如，该第二设备可以是gNB)确定至少两种BLER。
在本申请实施例中，第二设备可以通过如下方式确定第一设备(即，第一设备的一例，例如，该第一设备可以为UE)上报的至少两种BLER对应的CQI但本申请不限于此。
方式1，通信系统或通信协议可以规定至少两种误块率(block error ratio，BLER)，例如，该两种BLER可以分别为10 -1的BLER、10 -2的BLER，或者10 -1的BLER、10 -3的BLER等。本申请中也可以规定三种BLER、四种BLER等，以两种BLER为例，并不仅限制于此，只要规定至少两种即可。
方式2，第二设备可以基于第一设备的业务需求，为第一设备指示至少两种误块率 BLER。
方式3，第二设备可以基于第二设备的业务负载量(例如，图1中UE4所服务的UE 5和UE 6)，为第一设备指示至少两种误块率BLER。例如，如果第二设备所服务的终端设备较多，则第二设备可以为第一设备指示较松(即BLER的上限值较大)的BLER值；如果第二设备所服务的终端设备较少，则第二设备可以为第一设备指示较严苛(即BLER的上限值较小)的BLER值。
可选地，步骤220，第二设备向第一设备发送第一指示信息，该第一指示信息用于指示至少两种误块率BLER。相应的，第一设备接收第二设备发送的第一指示信息。
第二设备通过上述第一指示信息向第一设备指示至少两种BLER。为了便于让BLER值和其相应的CQI对应，这里，可以定义某种特定的排列顺序。至少两种BLER在第一指示信息中的排列顺序可以通过以下两种方式来实现。本申请并不仅限于此。
方式X，至少两种BLER在第一指示信息中的排列顺序可以是预定义的。例如，至少两种BLER在第一指示信息中排列顺序可以是按照从小到大或者从大到小的顺序排列。
方式Y，至少两种BLER在第一指示信息中的排列顺序也可以是第二设备为第一设备配置的。
可选地，至少两种BLER在第一指示信息中排列顺序的呈现形式也可以是BLER值(例如BLER的上限值)的排列顺序，也可以是BLER对应的索引的排列顺序，这里不再详细描述。
可选地，至少两种BLER在第一指示信息中排列顺序的呈现形式可以有如下两种。
顺序1，至少两种BLER在第一指示信息中的排列顺序的呈现形式可以是BLER值的排列顺序。
例如，当第二设备给第一设备指示了5种BLER时，即BLER的上限值分别为10 -5、10 -4、10 -3、10 -2、10 -1时，该5种BLER可以分别被按照BLER值从小到大的顺序排列，即10 -5、10 -4、10 -3、10 -2、10 -1的排列顺序；BLER也可以分别被按照从大到小的顺序排列，即10 -1、10 -2、10 -3、10 -4、10 -5的排列顺序。
又例如，当第二设备给第一设备指示了3种BLER时，即BLER的上限值分别为10 -5、10 -3、10 -1时，该3种BLER可以分别按照从小到大的顺序排列，即10 -5、10 -3、10 -1的排列顺序；BLER也可以分别按照从大到小的顺序排列，即10 -1、10 -3、10 -5的排列顺序。
顺序2，至少两种BLER在第一指示信息中的排列顺序的呈现形式可以是BLER对应的索引的排列顺序。可选地，10 -5、10 -4、10 -3、10 -2、10 -1的BLER分别对应的索引可以分别为1、2、3、4、5。
例如，当第二设备给第一设备指示了5种BLER时，即BLER的上限值分别为10 -5、10 -4、10 -3、10 -2、10 -1时，该5种BLER可以分别被按照BLER对应的索引从小到大的顺序排列，即1、2、3、4、5的排列顺序；该5种BLER可以分别被按照BLER对应的索引从大到小的顺序排列，即5、4、3、2、1的排列顺序。
又例如，当第二设备给第一设备指示了2种BLER时，即BLER的上限值分别为10 -5、10 -2时，该2种BLER可以分别被按照BLER对应的索引从小到大的顺序排列，即1、5的排列顺序；该2种BLER可以分别被按照BLER对应的索引从大到小的顺序排列，即5、1的排列顺序。
本申请对至少两种BLER在第一指示信息中的排列顺序不作限定，同时，本申请对BLER和BLER对应的索引之间的对应关系也不作限定。
步骤230，第二设备接收第一设备上报的至少两种BLER对应的信道质量指示CQI；相应的，根据第一指示信息，第一设备向第二设备上报至少两种BLER对应的信道质量指示CQI。
可选地，第二设备可以通过物理上行信道资源接收第一设备上报的所述至少两种BLER对应的CQI。其中，物理上行信道资源可以是控制信道上的物理上行控制信道资源，也可以是数据信道上的物理上行控制信道资源。
可选地，第一设备可以通过一个物理上行控制信道资源，也可以通过多个物理上行控制信道资源，向第二设备上报M种BLER中的N种BLER对应的CQI，其中，N小于或等于M，且N大于或等于1，M大于或等于2。下面将针对这两种情况，分别描述本申请实施例中，第一设备向第二设备上报至少M种BLER或至少M种BLER中的N种BLER对应的信道质量指示CQI。
情况1，第一设备可以向第二设备上报M种BLER对应上的CQI，且M≥2。
示例性地，第一设备通过M两个物理上行控制信道资源向所述第二设备上报M种BLER分别对应的信道质量指示CQI，M个物理上行控制信道资源分别与M种BLER对应。
示例性地，第二设备给第一设备指示了两种BLER，第一BLER(例如，可以是BLER的上限值为10 -4)和第二BLER(例如，可以是BLER的上限值为10 -3)，第一设备可以根据映射关系，分别通过与这两种BLER对应的物理上行控制信道资源，将这两种BLER分别对应的CQI上报给第二设备。该映射关系可以是包括第一BLER和第二BLER在内的多种BLER与包括第一物理上行控制信道资源和第二物理上行控制信道资源在内的多个物理上行控制信道资源的对应关系。
可选地，该映射关系可以是预定义的或是由第二设备，即网络设备配置的。
例如，第一物理上行控制信道资源可以与10 -1的BLER相对应，第二物理上行控制信道资源可以与10 -2的BLER相对应；或者，第一物理上行控制信道资源可以与10 -3的BLER相对应，第二物理上行控制信道资源可以与10 -1的BLER相对应；或者，第一物理上行控制信道资源可以与10 -2的BLER相对应，第二物理上行控制信道资源可以与10 -3的BLER相对应；本申请不仅限于2种BLER与2个物理上行控制信道资源之间的映射关系，也可以预先定义多种BLER与多个物理上行控制信道资源的对应关系，第一设备根据需要上报的BLER与相应的物理上行控制信道资源的对应关系，再选取相应的映射关系。
例如，第一设备可以通过第一物理上行控制信道资源向第二设备上报第一BLER对应的第一CQI，其中，第一物理上行控制信道资源与第一BLER对应，第一BLER包括在M种BLER中，第一物理上行控制信道资源包括在M个物理上行控制信道资源中；
又例如，第一设备可以通过第二物理上行控制信道资源向第二设备上报第二BLER对应的第二CQI，其中，第二物理上行控制信道资源与第二BLER对应，第二BLER包括在至少两种BLER中，第二物理上行控制信道资源包括在至少两个物理上行控制信道资源中。
第二设备接收第一设备上报的两种BLER对应的CQI值时，第二设备需要确定所接 收的CQI是由哪个物理上行控制信道资源承载的。
可选地，第二设备在进行盲检时，获取了第一CQI、第二CQI，但是第二设备并不知道该第一CQI和该第二CQI分别对应的BLER是哪种，所以，第二设备可以根据映射关系，确定该物理上行控制信道上报的CQI对应的是哪种BLER。
例如，物理上行控制信道资源有两个，即第一物理上行控制信道资源和第二物理上行控制信道资源，第一设备需要上报的BLER有2种，此时，第二设备需要确定承载该第一CQI的物理上行控制信道资源是第一物理上行控制信道资源还是第二物理上行控制信道资源，确定承载该第二CQI的物理上行控制信道资源是第一物理上行控制信道资源还是第二物理上行控制信道资源。如果第二设备确定承载第一CQI的物理上行控制信道资源是第一物理上行控制信道资源，根据映射关系，即可确定该第一CQI对应的BLER是第一BLER；如果第二设备确定承载第二CQI的物理上行控制信道资源是第二物理上行控制信道资源，根据映射关系，即可确定该第二CQI对应的BLER是第二BLER。
可选地，在物理上行控制信道资源的数量大于或等于BLER数量的情况下，该M种BLER对应的CQI承载于M个物理上行控制信道资源。即第一设备可以将每种BLER与一个物理上行控制信道资源一一对应向第二设备上报，从而第一设备能够合理地使用物理上行控制信道资源，向第二设备上报至少两种BLER对应的CQI，从而合理的分配下行传输数据块的大小，保证第一设备获取较好的下行性能。
情况2，第一设备可以向第二设备上报M种BLER中的N种BLER对应的CQI，且M≥2，1≤N，且N＜M。
示例性地，第一设备可以通过N个物理上行信道资源向所述第二设备上报N种BLER分别对应的信道质量指示CQI，N个物理上行信道资源分别与N种BLER对应。
示例性地，第二设备给第一设备指示了两种BLER，第一BLER(例如，可以是BLER的上限值为10 -4)和第二BLER(例如，可以是BLER的上限值为10 -3)，第一设备可以上报第一BLER和第二BLER中的一种BLER对应的CQI。
示例性地，第二设备给第一设备指示了三种BLER，第一BLER(例如，可以是BLER的上限值为10 -4)、第二BLER(例如，可以是BLER的上限值为10 -3)、第三BLER(例如，可以是BLER的上限值为10 -2)，第一设备可以上报第一BLER、第二BLER、第三BLER中的一种BLER或两种BLER对应的CQI。
示例性地，第一设备可以通过N个物理上行信道资源对N种BLER对应的CQI进行上报，该物理上行信道与BLER的对应关系可以按照上述的映射关系，这里不再详细描述。
示例性地，第一设备可以通过一个物理上行信道资源对N种BLER对应的CQI进行上报。
可选地，若第二设备给第一设备指示了三种BLER，第一设备可以上报第一BLER、第二BLER、第三BLER中的两种BLER对应的CQI，此时，第一设备可以采用上述顺序1或顺序2进行CQI上报。
示例性地，顺序1中BLER依次按照10 -4、10 -3、10 -2的顺序排列，第一设备可向第二设备上报顺序1中前2种BLER对应的CQI，即第一设备将10 -4的BLER对应的CQI、10 -3的BLER对应的CQI上报给第二设备；又例如，第一设备也可向第二设备上报顺序1中后2种BLER对应的CQI，即第一设备可将10 -3的BLER对应的CQI、10 -2的BLER对应 的CQI上报给第二设备。
示例性地，顺序2中BLER对应的索引依次按照2(BLER上限值为10 -4)、3(BLER上限值为10 -3)、4(BLER上限值为10 -2)的顺序排列，第一设备可向第二设备上报顺序2中前2种BLER对应的索引2和3所对应的BLER对应的CQI，即第一设备将BLER对应的索引2对应的10 -4的BLER对应的CQI、BLER对应的索引3对应的10 -3的BLER对应的CQI上报给第二设备；又例如，第一设备也可向第二设备上报顺序1中后2种BLER对应的索引3和4所对应的BLER对应的CQI，即第一设备可将BLER对应的索引3对应的10 -3的BLER对应的CQI、BLER对应的索引4对应的10 -2的BLER对应的CQI上报给第二设备。
示例性地，在物理上行控制信道资源的数量小于BLER数量的情况下，第一设备可以选取M种BLER中N种BLER对应的CQI承载于N个物理上行控制信道资源，向第二设备上报。
可选地，在当前可用物理上行信道资源有限的情况下，第一设备上报的BLER个数N是由物理上行信道资源的数量决定，本申请对此不作限定。
示例性地，物理上行控制信道资源有两个，即第一物理上行控制信道资源和第二物理上行控制信道资源，第一设备需要上报的BLER有2种。当第二设备在进行盲检时，第二设备需要确定承载该2种BLER对应的CQI的物理上行控制信道资源是第一物理上行控制信道资源还是第二物理上行控制信道资源，如果第二设备确定承载2种BLER对应的CQI的物理上行控制信道资源是第一物理上行控制信道资源，则第二设备还需要继续确定这2种BLER对应的CQI在第一物理上行控制信道资源上的排列顺序，即2种BLER对应的CQI是按上述顺序1或顺序2或其他预设置的顺序排列的，从而确定这2个CQI分别对应的是哪种BLER。图3从设备交互的角度示出的本申请实施例提供的另一种信道质量指示的上报方法300的示意性流程图。该实施例提供的信道质量指示的上报方法300还可在方法200的基础上包括步骤310-步骤320。
步骤310，第二设备确定目标BLER。
当第一设备上报了至少两种BLER时，第二设备可以基于以下三种方式，从上报的至少两种BLER中，确定目标BLER。
方式A，第二设备可以基于第二设备的业务负载量，确定目标BLER。
示例性地，在第二设备的业务负载量小于或等于第一阈值的情况下，第二设备将至少两种BLER中的第一BLER确定为目标BLER；
示例性地，在第二设备的业务负载量大于第一阈值的情况下，所第二设备将所述至少两种BLER中的第二BLER确定为目标BLER。
可以理解的是，本申请实施例中，第一BLER小于第二BLER。第二设备的业务负载量，即第二设备所服务的终端设备的数量或所服务终端设备业务需求的高低。
方式B，第二设备可以基于第一设备的业务延时值，确定目标BLER。
示例性地，在第一设备的业务延时值小于或等于第二阈值的情况下，第二设备将所述至少两种BLER中的第三BLER确定为目标BLER；
示例性地，在第一设备的业务延时值大于第二阈值的情况下，第二设备将所述至少两种BLER中的第四BLER确定为目标BLER。
可以理解的是，本申请实施例中，第三BLER小于第四BLER。第一设备的业务延时值可以是预定义的延时值或者基于第二设备与第一设备前一次数据传输的延时值。
方式C，第二设备可以基于第一设备的业务延时值和第二设备的业务负载量，确定目标BLER。
示例性地，在第二设备的业务负载量小于或等于第一阈值且第一设备的业务延时值小于或等于第二阈值的情况下，第二设备将所述至少两种BLER中的第五BLER确定为目标BLER；
示例性地，在第二设备的业务负载量大于第一阈值且第一设备的业务延时值大于第二阈值的情况下，第二设备将至少两种BLER中的第六BLER确定为目标BLER。
可以理解的是，本申请实施例中，第五BLER小于第六BLER。
可选地，第一阈值、第二阈值可以是预定义的，也可以是由网络设备(例如第二设备)配置的。其中，第一阈值可以是业务负载量，第二阈值可以是业务延时值，本实施例不限于此。
例如，第二设备从上报的N种BLER对应的CQI中，确定可以采用的目标BLER的上限值为10 -1。步骤320，第二设备根据目标BLER对应的CQI为第一设备配置传输参数。
可选地，传输参数包括MCS。例如，第二设备确定的目标BLER为10 -1，该目标BLER对应的CQI为10，第二设备可以根据表1中，CQI索引值为10时，对应的效率为2.7305，第二设备可以根据该效率值，从MCS表中找到小于该效率值所对应的MCS索引。
可选地，传输参数包括调制方式，该调制方式可以是正交相移键控(quadrature phase shift keying，QPSK)，也可以为16种符号的正交幅度调制(quadrature amplitude modulation，QAM)，也可以是64种符号的QAM，也可以为256种符号的QAM。调制方式的选取，主要取决于BLER的上限值和CQI值。
本申请另一实施例提供的信道质量指示的上报方法300还可包括步骤260。如图3中虚线部分所示。
步骤330，第二设备向第一设备发送第二指示信息，该第二指示信息用于指示目标BLER和所述目标BLER对应的传输参数。相应的，第一设备接收第二设备发送的第二指示信息。
可选地，该第二指示信息可通过下行控制信息(downlink control information，DCI)显式指示或通过无线网络临时标识符(radio network temporary identity，RNTI)隐式指示。
例如，第二设备可以将目标BLER和目标BLER对应的传输参数直接承载于DCI信息中，向第一设备发送该DCI，第一设备通过接收该DCI，可以从该DCI中获取目标BLER和目标BLER对应的传输参数。
又例如，第二设备可以为第一设备配置K(K为大于或等于1的整数)个RNTI，一个RNTI可以对应至少一种BLER。第一设备接收该DCI时，可以尝试使用上述K个RNTI对该DCI进行接收(例如，尝试使用上述K个RNTI对该DCI包含的校验信息进行校验或解扰)。若第一设备使用上述K个RNTI中的第k个RNTI(其中1≤k≤K)成功接收该DCI(例如，使用上述K个RNTI中的第k个RNTI成功校验或成功解扰了校验信息)，则第一设备可根据上述第k个RNTI与至少一种BLER的对应关系，获得该至少一种BLER为目标BLER，并可以进一步获得该目标BLER对应的传输参数。
在第二设备向第一设备发送了所述目标BLER对应的传输参数后，第二设备就可以采用为第一设备分配相应的传输数据块的大小、PDSCH信道的码数、编码方式、调制方式，从而第二设备和第一设备之间就可以进行数据传输。
本申请实施例中，第二设备通过第一设备上报的至少两种BLER，确定上报每种BLER所采用的物理上行控制信道资源或采用几个物理上行控制信道资源，从而合理地使用网络物理上行控制信道资源，并为第一设备合理的分配相应的传输数据块的大小、PDSCH信道的码数、编码方式、调制方式等。
