Description

信息确定方法和装置

背景技术
第五代(5th generation，5G)移动通信系统可以支持三种业务类型：增强移动带宽(enhanced mobile broadband，eMBB)、高可靠低时延传输(ultra-reliable and low latency communications，uRLLC)和大规模物联网(massive machine type communications，mMTC)。其中，uRLLC要求超高的传输可靠性和超低的传输时延。为了达到uRLLC的可靠性要求，网络设备可以采用多个传输接收节点(transmission and reception point，TRP)同时向终端设备传输相同数据的不同冗余版本(redundancy version，RV)，可以大大提高数据传输的可靠性。
当网络设备通过采用两个TRP传输同一数据给终端设备时，采用的频域资源、RV和调制编码方案(modulation and coding scheme，MCS)都可能不同。现有技术中，网络设备通过两个消息分别将两个TRP采用的频域资源、RV和MCS等参数发送给终端设备。一方面，会增加时频资源的开销，另一方面，会增加终端设备的计算复杂度和能耗。

具体实施方式
本申请将围绕可包括多个设备、组件、模块等的系统来呈现各个方面、实施例或特征。应当理解和明白的是，各个系统可以包括另外的设备、组件、模块等，并且/或者可以并不包括结合附图讨论的所有设备、组件、模块等。此外，还可以使用这些方案的组合。

本申请实施例中，网络设备(包括TRP)是一种部署在无线接入网中为终端设备提供无线通信功能的装置。网络设备可以包括各种形式的宏基站，微基站(也称为小站)，中继站，接入点等。在采用不同的无线接入技术的系统中，网络设备的名称可能会有所不同，例如全球移动通信系统(global system for mobile communication，GSM)或码分多址CDMA(code division multiple access，)网络中的基站收发信台(base transceiver station，BTS)，宽带码分多址(wideband code division multiple access，WCDMA)中的NB(NodeB)，长期演进(long term evolution，LTE)中的eNB或eNodeB(evolutional NodeB)。网络设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器。网络设备还可以是未来5G网络中的基站设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)网络中的网络设备。网络设备还可以是可穿戴设备或车载设备。
本申请实施例采用多个TRP向终端设备传输数据，因此网络设备可以指这些TRP，也可以是指这些TRP以及其他网络端的设备组成的一个整体。一般的，每个TRP采用一个传输配置编号状态(transmission configuration index-state，TCI-state)来进行传输，可以认为一个TCI-state就对应一个TRP，因此本申请中TCI-state和TRP是可以互相替换的。
本申请实施例中，所涉及到的终端设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。终端可以是移动站(mobile station，MS)、用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handset)、膝上型电脑(laptop computer)、机器类型通信(machine type communication，MTC)终端等。

在一个示例中，所述BBU 202可以由一个或多个单板构成，多个单板可以共同支持单一接入制式的无线接入网(如LTE网)，也可以分别支持不同接入制式的无线接入网(如LTE网、5G网或其他网)。所述BBU 202还包括存储器2021和处理器2022。所述存储器2021用以存储必要的指令和数据。所述处理器2022用于控制网络设备进行必要的动作，例如用于控制网络设备执行本申请方法实施例中关于网络设备的操作流程。所述存储器2021和处理器2022可以服务于一个或多个单板。也就是说，可以每个单板上单独设置存储器和处理器。也可以是多个单板共用相同的存储器和处理器。此外每个单板上还可以设置有必要的电路。
另外，网络设备不限于上述形态，也可以是其它形态：例如：包括BBU和自适应无线单元(adaptive radio unit，ARU)，或BBU和有源天线单元(active antenna unit，AAU)；也可以为客户终端设备(customer premises equipment，CPE)，还可以为其它形态，本申请不限定。
本申请实施例提供了一种信息确定方法，利用DCI中已有字段来指示网络设备通过两个TRP传输数据所采用的频域资源、RV和MCS等参数，不会增加时频资源的开销。或者换句话说，利用DCI中已有字段来指示网络设备通过两个TCI-state传输数据所采用的频域资源、RV和MCS等参数，不会增加时频资源的开销。
如图3所示，该信息确定方法包括步骤S301-S304：
S301、网络设备确定第一指示信息、第二指示信息和下行控制信息DCI。
本步骤也可以由网络设备中的芯片或芯片系统执行。需要说明的是，本步骤并不一定会显式地执行。
首先对第一指示信息和第二指示信息进行描述：
其中，第一指示信息用于指示单个DCI可调度的最大码字数，第一指示信息可以以参数maxNrofCodeWordsScheduledByDCI来表示，但本申请并不限定该参数的命名方式。单个DCI可调度的最大码字数可以为1或2。
第二指示信息用于指示数据传输的方式(例如，重复方式(repetition pattern))。数据传输的方式可以包括：
方式1、在同一时间单元，网络设备采用不同的TCI-state，在相同的频域资源上分别发送一个RV。这些RV是根据同一数据生成的同一RV，对应同一个码字。每个TCI-state对应k(k>＝1)个解调参考信号(demodulation reference signal，DMRS)端口。
方式2、在同一时间单元，网络设备采用不同的TCI-state，在不同的频域资源上分别发送一个RV。这些RV可以是根据同一数据生成的同一RV，也可以是根据同一数据生成的不同RV。这些RV可以全部对应同一码字，也可以分别对应不同码字。根据这些RV对应的是同一码字还是不同码字，方式2还可以进一步分为以下两种方式(方式2-1以及方式2-2)。
方式2-1：在同一时间单元，网络设备采用不同的TCI-state，在不同的频域资源上分别发送一个RV。这些RV是同一数据生成的同一RV，所有RV对应一个码字。
方式2-2：在同一时间单元，网络设备采用不同的TCI-state，在不同的时频资源上分别发送一个RV。这些RV是同一数据生成的同一RV或不同RV，每个RV对应一个码字。
方式3：在连续多个时间单元，网络设备采用多个TCI-state分别发送一个RV。这些RV是同一数据生成的同一RV或不同RV。
上述时间单元可以是符号、时隙、子帧、帧或其他粒度的时间单元。终端设备可以通过能力上报信令上报是否支持上述数据传输的方式中的任意一种。
第二指示信息可以通过以下方式来指示上述数据传输的方式：
在一种可能的实施方式中，第二指示信息可以包括一个参数，用于指示上述方式中的一种。
示例性的，第二指示信息包括一个字段，该字段的四个不同的值分别对应上述四种方式，即方式1、方式2-1、方式2-2、方式3。
示例性的，第二指示信息包括一个字段，该字段的三个不同的值分别对应方式1、方式2、方式3。
当第二指示信息指示方式2时，进一步根据第一指示信息指示的单个DCI可调度的最大码字数来确定具体是方式2-1还是方式2-2。例如，第二指示信息指示方式2，第一指示信息指示单个DCI可调度的最大码字数为1，则可以确定数据传输的方式为方式2-1；或者，第二指示信息指示方式2，第一指示信息指示单个DCI可调度的最大码字数为2，则可以确定数据传输的方式为方式2-2。
或者，当第二指示信息指示方式2时，进一步通过各个TCI-state对应的RV的总数来确定具体是方式2-1还是方式2-2。例如，各TCI-state对应的RV总数为1，则可以确定数据传输的方式为方式2-1；各TCI-state对应的RV总数为2，则可以确定数据传输的方式为方式2-2。
在另一种可能的实施方式中，第二指示信息也可以包括多个参数，通过多个参数来指示上述数据传输的方式中的具体一种。
示例性的，第二指示信息包括同一数据连续传输的次数(例如pdsch-AggregationFactor参数)，以及，传输采用的TCI-state数或TCI-state的索引。例如，当第二指示信息指示同一数据连续传输的次数大于1并且传输采用的TCI-state数大于1时，可以确定数据传输的方式为方式3。也就是说，当第二指示信息指示同一数据连续传输的次数大于1并且传输采用的TCI-state数大于1时(例如pdsch-AggregationFactor参数的值配置成大于1的值)，终端设备确定上述多个TCI-state是用于时分传输的，即在不同的时间单元依次采用上述多个TCI-state中的一个进行传输。当第二指示信息指示同一数据连续传输的次数等于1或者未指示同一数据连续传输的次数(例如未配置pdsch-AggregationFactor参数)，并且传输采用的TCI-state数大于1时，终端设备确定上述多个TCI-state是用于同时传输的，即在同一次传输中采用上述多个TCI-state同时进行传输。
进一步地，根据同一数据连续传输的次数以及传输采用的TCI-state数还可以确定各次传输采用的TCI-state。例如，第二指示信息指示了同一数据连续传输的次数为k并且传输采用k个TCI-state，则可以确定k次传输采用的TCI-state分别为指示的k个TCI-state中的一个。
具体的，可以根据k个TCI-state的索引递增或递减的顺序确定各次传输对应的TCI-state。例如，各次传输对应的TCI-state的索引依次递增或依次递减。
或者，也可以根据第二指示信息指示的k个TCI-state被指示的顺序确定各次传输对应的TCI-state。例如，第二指示信息指示两个TCI-state{TCI#2，TCI#1}，则可以确定第一次传输采用TCI#2对应的TCI-state，第二次传输采用TCI#1对应的TCI-state。
或者，也可以根据k个TCI-state关联的DMRS端口索引、DMRS端口组的索引或DMRS端口码分复用(code division multiplexing，CDM)组的索引递增或递减的顺序确定各次传输采用的TCI-state。例如，第二指示信息指示两个TCI-state{TCI#2，TCI#1}，其中，TCI#2对应的TCI-state与较小的DMRS端口、DMRS端口组或DMRS端口CDM组关联，TCI#1对应的TCI-state与较大的DMRS端口、DMRS端口组或DMRS端口CDM组关联，则第一次传输采用TCI#2对应的TCI-state，第二次传输采用TCI#1对应的TCI-state。在上述例子中，各次传输采用的DMRS端口、DMRS端口组或DMRS端口CDM组的索引依次增大。可选的，各次传输采用的DMRS端口、DMRS端口组或DMRS端口CDM组的索引也可以依次减小。此时第一次传输采用TCI#1对应的TCI-state，第二次传输采用TCI#2对应的TCI-state。
上述方案中，当第二指示信息的TCI-state个数小于同一数据连续传输的次数时，可以按照上述顺序依次循环采用各个TCI-state来进行各次传输。例如，第二指示信息指示了两个TCI-state{TCI#2，TCI#1}，并且第二指示信息指示了同一数据连续传输的次数为4，那么四次传输采用的TCI-state分别为{TCI#2，TCI#1，TCI#2，TCI#1}。
另外，第二指示信息指示的TCI-state数大于1并且同一数据连续传输的次数等于1时，第二指示信息指示的多个TCI-state用于同一次传输，即终端设备确定网络设备会采用上述多个TCI-state同时进行数据传输，这时终端设备需要根据上述TCI-state 进行数据的接收。具体的，当第一指示信息指示的单个DCI可调度的最大码字数大于1，第二指示信息指示的TCI-state数大于1时，终端设备可以确定网络设备是采用方式2-2进行传输。
上述方案中，k个TCI-state可以通过DCI中的TCI字段来指示，例如，TCI字段的每个值可以对应多个TCI-state。同一数据连续传输的次数可以通过一个无线资源控制(radio resource control，RRC)参数(例如pdsch-AggregationFactor)来进行指示。
第二指示信息指示数据传输的方式为方式3时，还可以指示以下信息中的一种或多种：同一数据连续传输的次数、各次传输采用的时间长度(例如正交频分复用(orthogonal frequency division multiplexing，OFDM)符号数)、各次传输采用的时域资源粒度(例如符号级、迷你时隙(mini-slot)级或时隙(slot)级)、传输的RV数、传输次数与RV的映射规则(各次传输分别采用哪个RV)、TCI-state与RV的映射规则(各个TCI-state分别对应哪个RV)、各次传输采用的TCI-state或TCI-state数。
下面对DCI进行描述：
如图4所示，R15的DCI格式1-1(DCI format 1-1)定义了两组传输参数字段(第一组传输参数字段和第二组传输参数字段)，每组传输参数字段包括MCS字段、新数据指示(new data indicator，NDI)字段和RV字段。每组传输参数字段对应一个传输块(transport block，TB)。
从网络设备侧来看，网络设备需要确定其发送的DCI中应该包括几组传输参数字段。分为两种情况：当只调度了一个TB时，对应的DCI中只包括第一组传输参数字段，用于指示该TB的MCS、NDI和RV等传输参数。当调度了两个TB时，对应的DCI中包括上述两组传输参数字段，分别用于指示各TB的传输参数。从终端设备侧来看，终端设备收到一个DCI后，需要确定该DCI中包括了几组传输参数字段。同样分两种情况：如果第一指示信息指示单个DCI可调度的最大码字数为2时，则确定该DCI中包括了上述两组传输参数字段；否则，确定该DCI中只包括第一组传输参数字段。
本申请实施例中，一组传输参数字段是指基于码字或基于TB进行划分的一组字段，每组传输参数字段对应于一个码字或对应一个TB。例如，在R15中一组传输参数字段包括MCS字段、NDI字段和RV字段，而本申请不限定一组传输参数字段中包括的字段数。可选的，每组传输参数字段还可以包括其他除MCS字段、NDI字段和RV字段以外的字段。
本申请实施例中，DCI可以包括第一组传输参数字段和第二组传输参数字段，第一组传输参数字段对应第一数据，第二组传输参数字段对应第二数据。第一数据和第二数据可以是以下任意一种：两个码字、两个RV、两个TCI-state对应的数据、两个DMRS端口或端口组对应的数据、两个DMRS端口CDM组对应的数据、两个TRP传输的数据。
下面对DCI包括第一组传输参数字段和第一组传输参数字段的几种方式进行描述：
方式一、如果第一指示信息指示第一条件不满足，则DCI中只包括第一组传输参数字段。
其中，第一条件可以包括单个DCI可调度的最大码字数为2。例如，第一指示信 息包括参数maxNrofCodeWordsScheduledByDCI，该参数的值为1时，确定第一条件不满足。
方式二、如果第一指示信息指示第一条件满足，并且第二指示信息指示第二条件不满足，则从DCI中确定两组传输参数字段(第一组传输参数字段和第二组传输参数字段)，第一组传输参数字段和第二组传输参数字段分别对应两个不同的TB。
方式三、如果第一指示信息指示第一条件满足，并且第二指示信息指示第二条件满足，则确定DCI中包括两组传输参数字段(第一组传输参数字段和第二组传输参数字段)，第一组传输参数字段对应第一数据，第二组传输参数字段对应第二数据。第一数据和第二数据可以是同一TB对应的两个码字。例如，同一TB进行编码生成四个RV，从四个RV中选择两个不同的RV作为两个码字进行传输，或者从四个RV中选择一个RV，将该RV作为两个码字进行重复传输。第一数据和第二数据可以是两个相同的TB各自确定的一个码字。例如，将两个内容相同的TB分别进行编码，分别生成四个RV，从每个TB对应的四个RV中各选择1个RV，来作为两个码字进行传输。
其中，第二条件可以是指网络设备在不同的频域资源上分别发送同一数据对应的两个码字。或者，网络设备同时采用多个TCI-state传输同一数据对应的多个码字或多个RV给终端设备。或者，第二条件可以是指网络设备同时采用不同的频域资源传输同一数据对应的多个码字或多个RV给终端设备。或者，第二条件可以是指网络设备同时采用多个TCI-state分别在不同的频域资源传输同一数据对应的多个码字或多个RV给终端设备。本申请并不限定第二条件的描述方式，只要能达到上述列举的第二条件对应的传输效果，即可认为是满足第二条件。例如，第二指示信息指示数据传输的方式为方式2-2时，也可以认为第二条件满足。
本申请实施例中，第一组传输参数字段包括第一数据的MCS字段、NDI字段和RV字段的具体含义与现有技术相同，此处不再赘述。下面着重对第二组传输参数字段进行详细说明。
第二组传输参数字段包括第二数据的MCS字段、NDI字段和RV字段。其中，第二数据采用第一组传输参数字段的NDI字段指示的新数据指示信息，即第二数据的RV信息与第一数据的RV信息相同。第二组传输参数字段的RV字段仍用于指示第二数据的RV信息。
第二数据的MCS字段或者，第二数据的MCS字段和NDI字段用于指示以下信息中的一种或多种的组合：第二数据采用的调制阶数，第二数据采用的码率，第二数据的频率资源信息。
其中，频率资源信息包括以下一种或多种的组合：频域资源偏移、频域资源偏移的粒度、频域资源数量差值、频域资源数量差值的粒度、频域资源分配类型。
第一数据的频域资源和第二数据的频域资源分别为一段连续的频域资源，两段连续的频域资源不重复。两段连续的频域资源可以是相连的。例如，第一数据的最后一个频域资源与第二数据的第一个频域资源是相邻的。或者第一数据的第一个频域资源与第二数据的最后一个频域资源是相邻的。两段连续的频域资源也可以有一定的频域资源偏移。
如图5所示，频域资源偏移为：A第二数据的频域资源的起始位置与第一数据的 频域资源的截止位置的偏移；或者，B第二数据的频域资源的起始位置与第一数据的频域资源的起始位置的偏移；或者，C第二数据的频域资源的截止位置与第一数据的频域资源的截止位置的偏移；或者，D第二数据的频域资源的截止位置与第一数据的频域资源的起始位置的偏移；或者，E第一数据的频域资源的起始位置与第二数据的频域资源的截止位置的偏移；或者，F第一数据的频域资源的起始位置与第二数据的频域资源的起始位置的偏移；或者，G第一数据的频域资源的截止位置与第二数据的频域资源的截止位置的偏移；或者，H第一数据的频域资源的截止位置与第二数据的频域资源的起始位置的偏移。
可以按照频域资源索引递增的方式来确定第二数据的频域资源。例如，第一数据的频域资源的最后一个资源的索引加上频域资源偏移，得到第二数据的频域资源的第一个资源的索引。可以按照频域资源索引递减的方式来确定第二数据的频域资源。例如，第一数据的频域资源的第一个资源的索引减去频域资源偏移，得到第二数据的频域资源的最后一个资源的索引。
频域资源偏移需要满足一定约束条件。例如，根据频域资源偏移计算得到的第二数据的频域资源不能超出当前采用的载波(carrier)或带宽部分(bandwidth part，BWP)的频域资源范围。例如第二数据的最后一个RB或RBG的索引不能大于当前载波或BWP的最大RBG的索引，或者，第二数据的第一个RB或RBG的索引不能小于当前载波或BWP的最小RBG的索引。
相应地，频域资源分配需要满足上述约束条件。具体的，在进行频域资源分配时，第一数据的起始RB或RBG，第二数据的RB或RBG，第一数据分配的RB数或RBG数，第二数据分配的RB数或RBG数，以及第一数据和第二数据的频域资源偏移的值的确定，需要确保满足上述约束条件。
除了满足上述约束条件外，还可以采用另一种方法来避免分配的频域资源超出BWP的范围。
在一种可能的实施方式中，按照频域资源索引递增的方式来确定第二数据的频域资源，第二数据的频域资源的索引超过该BWP的最大频域资源索引时，回退到最小频域资源索引重新开始算起。例如，一个BWP包括20个RB(RB#0至RB#19)，第一数据的频域资源为RB{#10，#11，#12，#13，#14，#15}，频域资源偏移为3，因此计算得到第二数据的频域资源为RB{#18，#19，#20，#21，#22，#23}。由于RB{#20，#21，#22，#23}超过BWP的最大RB(#19)，因此回退到最小RB(#0)，即RB{#20，#21，#22，#23}换算为RB{#0，#1，#2，#3}，因此第二数据的频域资源为RB{#18，#19，#0，#1，#2，#3}。
在另一种可能的实施方式中，按照频域资源索引递减的方式来确定第二数据的频域资源，第二数据的频域资源的索引小于该BWP的最小频域资源索引时，回退到最大频域资源索引重新开始算起。例如，一个BWP包括20个RB(RB#0至RB#19)，第一数据的频域资源为RB{#5，#6，#7，#8，#9，#10}，频域资源偏移为3，因此计算得到第二数据的频域资源为RB{#-3，#-2，#-1，#0，#1，#2}。由于RB{#-3，#-2，#-1}小于BWP的最小RB(#0)，因此回退到最大RB(#19)，即RB{#-3，#-2，#-1}换算为RB{#17，#18，#19}，因此第二数据的频域资源为RB{#17，#18，#19，#0，#1， #2}。
频域资源偏移的粒度或频域资源数量差值的粒度为资源元素(resource element，RE)、资源块(resource block，RB)、资源块组(resource block group，RBG)、预编码资源块组(precoding resource block groups，PRG)或子带(subband)。
频域资源偏移可以是指两个RE、RB、RBG、PRG或子带(subband)之间的偏移。该偏移可以是两个RE、RB、RBG、PRG或子带的编号的差值，例如RB#10与RB#6之间的偏移为10-6＝4个RB。该偏移也可以是两个RE、RB、RBG、PRG或子带之间间隔的资源数。例如RB#10与RB#6之间间隔了3个RB，那么偏移为3个RB。频域资源可以是指RE、RB、RBG、PRG或子带。
当第一数据和第二数据采用的频域资源数相同时，网络设备只要指示频域资源偏移，根据第一数据的频域资源以及上述频域资源偏移即可以确定第二数据的频域资源。示例性的，如图5所示，第一数据和第二数据采用的频域资源数相同，以频率资源为RB为例，第一数据的频域资源对应RB#2～#6，第二数据的第一个RB(编号最小的RB)和第一数据的最后一个RB(编号最大的RB)之间的偏移为8，则可以确定第二数据的频域资源对应RB#10～14。
当第一数据和第二数据采用的频域资源数不同时，频域资源数量差值为第二数据的频域资源数量与第一数据的频域资源数量的差值，或者，第一数据的频域资源数量与第二数据的频域资源数量的差值。例如，当频域资源数量偏移的粒度是RB时，频域资源数量差值为4，表示相差4个RB。
频域资源偏移或频域资源数量差值可以通过无线资源控制RRC信令、媒体访问控制控制信元MAC-CE信令或DCI信令进行指示，或者，采用默认值，或者，采用终端设备上报的值。
下面举例对第二数据的MCS字段和NDI字段的各种可能实施方式进行说明：
在一种可能的实施方式中，第二数据的码率与第一数据相同，第二数据的调制阶数通过第二组传输参数字段中的MCS字段，或者，MCS字段和NDI字段来指示。或者，第二数据的调制阶数与第一数据相同，第二数据的码率通过第二组传输参数字段中的MCS字段，或者，MCS字段和NDI字段来指示。
在另一种可能的实施方式中，第二数据的MCS字段可以用于指示第二数据的调制阶数以及第二数据的频域资源偏移。如表1所示，每个MCS字段取值对应一个调制阶数的值以及一个频域资源偏移的值。
表1
MCS字段 调制阶数 频域资源偏移
00000 2 0
00001 4 0
00010 6 0
00011 8 0
00100 2 1
00101 4 1
00110 6 1
00111 8 1
… … …
11111 8 7
在又一种可能的实施方式中，第二数据的NDI字段用于指示频域资源偏移的粒度、频域资源数量差值的粒度、频域资源分配类型中的至少一项。
在又一种可能的实施方式中，因为MCS字段占用5比特，NDI字段占用1比特，所以可以将第二数据的MCS字段和NDI字段联合为6比特的字段来指示。第二数据的MCS字段和NDI字段用于指示以下信息中的一种或多种的组合：第二数据采用的调制阶数、频域资源偏移、频域资源偏移的粒度、频域资源数量差值、频域资源数量差值的粒度、频域资源分配类型。
S302、网络设备向终端设备发送第一指示信息、第二指示信息和DCI。
本步骤也可以由网络设备中的芯片或芯片系统执行。
上述第一指示信息、第二指示信息可以通过单个信令进行发送，也可以通过多个信令进行发送。例如，可以携带在RRC信令、媒体访问控制控制信元(medium access control-control element，MAC-CE)信令或DCI中。另外，第二指示信息包括的内容，可以承载在一个信令中，也可以承载在不同的信令中。
需要说明的是，步骤S302所述的几种数据传输的方式都是基于单个DCI进行调度的，即多个TRP传输的数据都是由单个DCI进行调度的。除了上述几种数据传输的方式外，网络设备还可以采用多个DCI来分别调度各个TRP传输的数据。例如，在一次传输中，每个TRP分别传输一个DCI给终端设备，各TRP发送的DCI分别用于指示该TRP发送的数据的相关参数。在这种情况下，为了使得终端设备能收到多个DCI，网络设备需要向终端设备指示其发送了多个DCI。具体的，可以采用以下方式来进行指示：
在一种可能的实施方式中，网络设备向终端设备发送第三指示信息，第三指示信息用于指示终端设备需要接收的DCI数。
在另一种可能的实施方式中，可以在DCI中通过一个字段来指示本次传输的DCI数，或指示是否还有其他DCI要接收。
在又一种可能的实施方式中，通过网络设备配置的控制资源集(control resource set，CORESET)数来指示。例如，当配置的CORESET数的大于特定门限值时，则指示终端设备需要接收多个DCI，否则指示终端设备只需要接收单个DCI。
在又一种可能的实施方式中，通过网络设备配置的CORESET关联的搜索空间(searchSpace)的类型来指示。例如，如果配置的各个CORESET关联的searchSpace中，类型为特定用户设备(ue-Specific)的searchSpace数大于1，则指示终端设备需要接收多个DCI。或者，如果关联的searchSpace的类型为ue-Specific的CORESET数大于1，则指示终端设备需要接收多个DCI。当终端设备需要接收多个DCI时，在一 次接收中，终端设备需要接收到两个DCI才会停止接收。
S303、终端设备从网络设备接收第一指示信息、第二指示信息和DCI。
本步骤也可以由终端设备中的芯片或芯片系统执行。
S304、终端设备从DCI中确定第一数据对应的第一组传输参数字段和第二数据对应的第二组传输参数字段。
本步骤也可以由终端设备中的芯片或芯片系统执行。
在一种可能的实施方式中，如果根据第一指示信息确定第一条件满足，则终端设备从DCI中确定第一数据对应的第一组传输参数字段和第二数据对应的第二组传输参数字段。
在另一种可能的实施方式中，如果根据第一指示信息确定第一条件满足，并且根据第二指示信息确定第二条件满足，则终端设备从DCI中确定第一数据对应的第一组传输参数字段和第二数据对应的第二组传输参数字段。
在又一种可能的实施方式中，如果根据第一指示信息确定第一条件满足，并且根据第二指示信息确定第二条件不满足，则终端设备确定DCI中第一组传输参数字段和第二组传输参数字段分别对应两个不同的传输块。
关于第一条件、第二条件的描述见前文，在此不再重复。
本申请实施例提供的信息确定方法，在网络设备指示两个TRP采用的频域资源、RV和MCS等参数时，在DCI的第一组传输参数字段中依旧指示第一数据的MCS字段、NDI字段和RV字段。在DCI的第二组传输参数字段中复用第二参数的MCS字段、NDI字段，用于指示以下信息中的一种或多种的组合：第二数据采用的调制阶数或码率中的一个，第二数据的频率资源信息。DCI的第二组传输参数字段中未指示的例如第二数据采用的调制阶数、码率、NDI等传输参数采用第一数据相同的传输参数。不必不扩展DCI数量或DCI字段，实现了在网络设备指示两个TRP采用的频域资源、RV和MCS等参数时，没有增加时频资源的开销。
可以理解的是，以上各个实施例中，由终端设备实现的方法和/或步骤，也可以由可用于终端设备的部件(例如芯片或者电路)实现，由网络设备实现的方法和/或步骤，也可以由可用于网络设备的部件实现。
