Description

控制信息的指示方法以及装置 技术领域
本申请实施例涉及通信技术领域。
背景技术
在新无线(NR，New Radio)系统中，需要支持一些低时延高可靠性的业务场景，例如AR/VR、工厂自动化、包括远程驾驶在内的交通运输场景、分布式电力系统控制等等。这些业务对时延的要求达到0.5ms-1ms的级别，可靠性的要求达到了1e-6级别。因此，5G系统需要研究兼具高可靠性和低时延性的传输技术，以满足这些业务场景。
为提高传输的可靠性，Rel-15已经支持了数据信道的重复传输，即同一个传输块(TB，Transport Block)的多个冗余版本(RV，Redundancy Version)在多个连续的时隙(slot)进行重复传输。
为了进一步提高传输的可靠性，以及进一步减小传输时延，Rel-16对数据信道的重复传输进行了增强。例如，使用多个传输点为终端设备传输相同的数据，以此增加传输的可靠性；又例如，重复传输的多个版本(也称为重复版本)可以在一个时隙内传完，即实现了mini-slot级别的重复传输。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
但是发明人发现：重复传输的多个相同或不同冗余版本可能使用不同的参数进行发送或接收(以下简称为发送或接收参数，或者称为参数；冗余版本简称为版本)，例如不同版本可能使用不同解调参考信号(DMRS，De-Modulation Reference Signal)天线端口和/或不同传输配置指示(TCI，Transmission Configuration Indication)状态来进行发送和接收。一个重复版本可以在一个时间单元上发送或接收，按照现有参数指示方案，接收设备无法区分出不同版本的参数，因此可能会错误地进行接收。

在本申请实施例中，术语“通信网络”或“无线通信网络”可以指符合如下任意通信标准的网络，例如长期演进(LTE，Long Term Evolution)、增强的长期演进(LTE-A，LTE-Advanced)、宽带码分多址接入(WCDMA，Wideband Code Division Multiple Access)、高速报文接入(HSPA，High-Speed Packet Access)等等。
并且，通信系统中设备之间的通信可以根据任意阶段的通信协议进行，例如可以包括但不限于如下通信协议：1G(generation)、2G、2.5G、2.75G、3G、4G、4.5G以及5G、新无线(NR，New Radio)等等，和/或其他目前已知或未来将被开发的通信协议。
在本申请实施例中，术语“网络设备”例如是指通信系统中将终端设备接入通信网络并为该终端设备提供服务的设备。网络设备可以包括但不限于如下设备：基站(BS，Base Station)、接入点(AP、Access Point)、发送接收点(TRP，Transmission Reception Point)、广播发射机、移动管理实体(MME、Mobile Management Entity)、网关、服务器、无线网络控制器(RNC，Radio Network Controller)、基站控制器(BSC，Base Station Controller)等等。
其中，基站可以包括但不限于：节点B(NodeB或NB)、演进节点B(eNodeB或eNB)以及5G基站(gNB)，等等，此外还可包括远端无线头(RRH，Remote Radio Head)、远端无线单元(RRU，Remote Radio Unit)、中继(relay)或者低功率节点(例如femeto、pico等等)。并且术语“基站”可以包括它们的一些或所有功能，每个基站可以对特定的地理区域提供通信覆盖。术语“小区”可以指的是基站和/或其覆盖区域，这取决于使用该术语的上下文。
在本申请实施例中，术语“用户设备”(UE，User Equipment)或者“终端设备”(TE，Terminal Equipment或Terminal Device)例如是指通过网络设备接入通信网络并接收网络服务的设备。终端设备可以是固定的或移动的，并且也可以称为移动台(MS，Mobile Station)、终端、用户台(SS，Subscriber Station)、接入终端(AT，Access Terminal)、站，等等。

以下通过示例对本申请实施例的场景进行说明，但本申请不限于此。
图1是本申请实施例的通信系统的示意图，示意性说明了以终端设备和网络设备为例的情况，如图1所示，通信系统100可以包括网络设备101和终端设备102、103。为简单起见，图1仅以两个终端设备和一个网络设备为例进行说明，但本申请实施例不限于此。
在本申请实施例中，网络设备101和终端设备102、103之间可以进行现有的业务或者未来可实施的业务传输。例如，这些业务可以包括但不限于：增强的移动宽带(eMBB，enhanced Mobile Broadband)、大规模机器类型通信(mMTC，massive Machine Type Communication)和高可靠低时延通信(URLLC，Ultra-Reliable and Low-Latency Communication)，等等。
值得注意的是，图1示出了两个终端设备102、103均处于网络设备101的覆盖范围内，但本申请不限于此。两个终端设备102、103可以均不在网络设备101的覆盖范围内，或者一个终端设备102在网络设备101的覆盖范围之内而另一个终端设备103在网络设备101的覆盖范围之外。
在本申请实施例中，多个重复版本可能来自不同的传输点或者使用不同的发送空间滤波器，例如使用多TRP或多面板(panel)操作时；此外，不同的重复版本可能使用不同的天线端口来发送。因而终端设备如何确定各个重复版本的参数(包括发送或接收参数，例如天线端口和QCL信息)是一个问题；以下示例性地进行说明。
例如，当使用多TRP或多panel操作时，多TRP或多panel操作相关模式可以通过高层信令显式地配置，也可以隐式地配置。例如，多TRP或多panel操作被显式地配置成一种或多种传输方案(transmission scheme)；也可以通过配置某些高层参数来隐式地指示终端设备可以进行多TRP或多panel操作，例如通过配置的解调参考信号(DMRS)端口组(port group)的数量，相位追踪参考信号(PTRS)的端口数，同时传输的控制信道(PDCCH)数量等来隐式地指示终端设备是否进行多TRP或多panel相关操作。
例如，当DMRS port group的(最大)数量或PTRS(最大)端口数或同时传输的PDCCH的(最大)数量大于阈值(例如1)时，终端设备确定为多TRP或多panel操作，否则终端设备确定为单TRP或单panel操作，或者为多TRP或多panel操作之外的操作。多TRP或多panel操作还可以是涉及多个TRP传输的方案，例如协作多点传输(CoMP，Coordinated Multi-point)、载波聚合(CA，Carrier Aggregation)、双 连接(DC，Dual Connectivity)等。
在Rel-15中，数据信道(例如物理下行共享信道PDSCH)的空间QCL关系通过无线资源控制(RRC，Radio Resource Control)信令，介质访问控制(MAC，Media Access Control)控制元素(CE，Control Element)以及下行控制信息(DCI，Downlink Control Information)联合地指示。
例如，首先RRC信令配置最多128个TCI状态，然后MAC-CE激活至多8个TCI状态，进而使用DCI中的'Transmission Configuration Indication'域为PDSCH指示使用的TCI状态。其中DCI中每个codepoint对应一个TCI状态，而每个TCI状态包含PDSCH的解调参考信号(DMRS)与一个或两个下行参考信号之间的准共址(QCL，quasi co-location)关系。对于2个下行参考信号(RS)的情况，两个RS的QCL类型不能相同，例如只有一个RS可以是type D，用于指示空间接收参数(spatial RX parameter)。
然而，当传输多个重复版本时，根据Rel-15的TCI状态指示和/或DMRS端口指示方法，终端设备无法知道某个重复版本所对应的或所使用的天线端口和/或TCI状态。
图2是本申请实施例的发送重复版本的示例图，如图2所示，重复传输的相同或不同版本(以重复1、重复2、重复3表示)分别在同一个的时隙的不同符号发送。例如，以协议TS38.212中的表7.3.1.2.2-1为例：
Table 7.3.1.2.2-1:天线端口(1000+DMRS port)，dmrs-Type＝1，maxLength＝1
Figure PCTCN2019098168-appb-000001
例如，DCI指示其调度的PDSCH的DMRS端口组合为value 11，即端口0和2。而TCI状态配置信息会指示端口0和2所使用的TCI状态。然而以图2中的调度样式(pattern)为例，终端设备无法知道每个重复版本(repetition)对应的DMRS天线端口以及该天线端口使用的TCI状态，仅能获得三个重复版本一起所使用的TCI状态和/或DMRS端口集合。
因而，终端设备如何确定各个重复版本的参数(包括发送或接收参数，例如天线端口和QCL信息)是一个问题，本申请实施例至少针对该技术问题提供以下技术方案。
值得注意的是，QCL信息或TCI状态等参数例如用于表示发送端的空间滤波器系数或波束成型的方向，具体的概念可以参考相关技术。此外，重复传输例如是为提高传输的可靠性而对一个传输块(TB)的相同版本或不同版本进行至少一次传输，至少一次重复传输可以分别在至少一个传输机会(或传输时机，transmission occasion) 或至少一个时间单元上进行，关于重复传输和传输机会的概念也可以参考相关技术。在不引起混淆的情况下，以上术语“重复传输”“传输时机”“传输机会”等可以互换。
此外，多次重复传输可以是时分复用的(TDM，Time Division Multiplexing)，包括时隙(slot)级别的或非时隙(例如non-slot，mini-slot，sub-slot)等级别的，可被称为slot级别的重复和非slot级别的重复。此外，多次重复传输也可以是频分复用的(FDM，Frequency Division Multiplexing)或空分复用的(SDM，Space Division Multiplexing)等，也可以是以上至少两种复用方式的结合，例如TDM+FDM，TDM+SDM等。
具体使用哪种传输方式取决于网络设备的配置和/或指示，例如通过RRC信令配置一种传输方式，例如非时隙级别的重复传输；或通过RRC信令+MAC-CE信令配置和指示，即使用RRC信令配置两种及两种以上传输方式，MAC-CE信令激活其中的一种传输方式；或者通过RRC信令+MAC-CE信令+DCI信令配置和指示，即使用RRC信令配置两种及两种以上传输方式，MAC-CE信令激活其中的一种或一种以上传输方式，再使用DCI信令指示其中的一种激活的传输方式作为最终传输时使用的方式；或者通过RRC信令+DCI信令配置和指示，即使用RRC信令配置两种及两种以上传输方式，DCI信令指示其中的一种传输方式作为最终传输时使用的方式，等等。
在以下的说明中，在不引起混淆的情况下，术语“上行控制信号”和“上行控制信息(UCI，Uplink Control Information)”或“物理上行控制信道(PUCCH，Physical Uplink Control Channel)”可以互换，术语“上行数据信号”和“上行数据信息”或“物理上行共享信道(PUSCH，Physical Uplink Shared Channel)”可以互换，术语“下行控制信号”和“下行控制信息(DCI，Downlink Control Information)”或“物理下行控制信道(PDCCH，Physical Downlink Control Channel)”可以互换，术语“下行数据信号”和“下行数据信息”或“物理下行共享信道(PDSCH，Physical Downlink Shared Channel)”可以互换。
第一方面的实施例
本申请实施例提供一种控制信息的指示方法，先从终端设备侧进行说明。图3是本申请实施例的控制信息的指示方法的一示意图，如图3所示，该方法包括：
301，终端设备接收网络设备发送的天线端口配置信息；以及
302，终端设备根据天线端口配置信息确定至少一个时间单元的发送或接收参数；其中一个时间单元对应至少一个发送或接收参数。
在本申请实施例中，至少一个时间单元用于传输一个传输块(TB)的相同或不同版本；天线端口配置信息配置或指示所述传输块的相同或不同版本的发送或接收参数。该时间单元例如可以是时隙、非时隙(例如non-slot，mini-slot，sub-slot)等，但本申请不限于此，例如还可以是一个或多个符号(symbol)等。此外，所述时间单元还可以扩展到其它资源单元上，例如频域单元、空域单元或空间传输层(layer)等。
所述天线端口配置信息可以是数据信道(例如PDSCH或PUSCH)的端口配置信息，也可以是控制信道(例如PDCCH或PUCCH)的端口配置信息，本申请不对此做限制。
相应地，本申请实施例还可以应用到所有传输块重复传输的场景下，例如传输块在频域上以TDM的方式进行重复传输，或者传输块在频域上以FDM的方式进行重复传输，或者传输块在空域上以SDM的方式进行重复传输，或者以上至少两种重复方式的组合，例如TDM+FDM，TDM+SDM，FDM+SDM，TDM+FDM+SDM等。
值得注意的是，以上附图3仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图3的记载。
在一些实施例中，发送或接收参数包括如下至少之一：传输点索引，小区索引，传输配置指示(TCI)状态索引，准共址(QCL)信息索引，天线端口索引，码分复用(CDM，Code Division Multiplexing)组索引，时域资源分配(TDRA，time domain resource allocation)，频域资源分配(FDRA，frequency domain resource allocation)；但本申请不限于此，还可以是其他的参数。
在一些实施例中，天线端口配置信息中的至少一个天线端口对应至少一个时间单元的发送天线端口，一个时间单元对应一个发送天线端口。
例如，所述天线端口配置信息中指示N个天线端口索引，N为大于或等于1的正整数。指示的N个天线端口分别对应N个重复版本使用的天线端口。
由此，网络设备可以通过天线端口配置信息直接指示每个重复版本或每个时间单元的发送天线端口，网络设备和终端设备对各个重复版本在传输时使用的天线端口有一致的理解。
值得注意的是，以上天线端口配置信息在控制信息中的‘Antenna port(s)’域传输，每一条天线端口配置信息对应控制信令中的一个码点(code point)，也对应标准中预定义的DMRS port table(例如TS38.212中的表7.3.1.2.2-1)的一个条目(entry)，也就是表7.3.1.2.2-1的一个值(value)及其对应的DMRS天线端口。
以TS38.212中的表7.3.1.2.2-1为例，其中DMRS端口列用于指示PDSCH的DMRS传输所使用的天线端口编号，以value 9为例，DMRS端口为0-2，表示指示DMRS端口的DCI调度的PDSCH的3个重复版本的DMRS使用天线端口1000、1001和1002进行传输。
在一些实施例中，天线端口配置信息中所指示的至少两个天线端口索引是相同的，或者是部分相同，或者各不相同。天线端口配置信息中所指示的至少两个天线端口索引属于不同的CDM组。
例如，CDM group和天线端口的对应关系可以沿用Rel-15的表7.4.1.1.2-1和表7.4.1.1.2-2。
表7.4.1.1.2-1:PDSCH DM-RS配置类型1的参数
(Table 7.4.1.1.2-1:Parameters for PDSCH DM-RS configuration type 1)
Figure PCTCN2019098168-appb-000002
表7.4.1.1.2-2:PDSCH DM-RS配置类型2的参数
(Table 7.4.1.1.2-2:Parameters for PDSCH DM-RS configuration type 2)
Figure PCTCN2019098168-appb-000003
在一些实施例中，为支持更多的端口指示样式，例如支持多TRP或多面板(panel)下的传输，支持指示的天线端口来自不同的CDM组和/或具有不同的TCI状态等，可以在DMRS表中加入如下的DMRS ports指示值：
Port a(in CDM group i)；port b(in CDM group j)；port c(in CDM group k)…
其中，a、b、c可以是相同的值，例如a＝b＝c；也可以是部分相同，例如a＝c，或a＝b，或b＝c。a、b、c并不总是按升序排列，例如可以是降序排列，a>b>c，也可以无顺序可言，例如a<b，c<b等。DMRS表中可能同时存在a、b、c和c、b、a，即它们对应不同的value值。
例如，当DMRS为类型1(dmrs-Type＝1)，最大长度为1(maxLength＝1)时，表7.3.1.2.2-1中各个值表示的DMRS端口对应的CDM group为：
Figure PCTCN2019098168-appb-000004
可以看出，只有value 9-11可以表示DMRS端口来自2个CDM group的情况，为了更好地支持指示的天线端口来自不同的CDM组和/或具有不同的TCI状态等，可以增加DMRS entry以增加更多的调度样式或重复样式。
例如，针对DMRS type 1，支持如下CDM组合的一种或者任意组合：
0,1；1,0；0,0；1,1；
1,0,1；0,0,0；1,1,1；0,1,0；0,1,1；1,0,0；1,1,0；0,0,1；
0,0,0,0；0,0,0,1；0,0,1,0；0,0,1,1；0,1,0,0；0,1,0,1；0,1,1,0；0,1,1,1；1,0,0,0；1,0,0,1；1,1,0,0；1,0,1,0；1,0,1,1；1,1,0,1；1,1,1,0；1,1,1,1；等等。
那么相应地，可以增加DMRS端口组合以支持以上CDM group组合。根据TS38.212中的表7.4.1.1.2-1中CDM group和天线端口的对应关系，CDM group 0对应的天线端口编号可以是{0,1,4,5}+1000中的至少一个，CDM group 1对应的天线端口编号可以是{2,3,6,7}+1000中的至少一个。为简化描述，以后提及的天线端口编号均为省略+1000的部分。
例如，以CDM group组合1,0为例，对应的DMRS端口组合可以是：port 2,0； 2,1；3,0；3,1；6,4；等等。
又例如，以CDM group组合为0,1,0为例，对应的DMRS端口组合可以是：port 0,2,0；0,3,0；0,2,1；0,3,1；1,2,1；1,3,1；1,2,0；1,3,0；0,2,1；0,3,1；等等。
又例如，以CDM group组合为1,0,1为例，对应的DMRS端口组合可以是：port 2,0,2；2,1,2；2,0,3；2,1,3；3,0,3；3,1,3；3,0,2；3,1,3；等等。
又例如，以CDM group组合0,1,0,1为例，对应的DMRS端口组合可以是：port 0,2,0,2；1,2,1,2；0,3,0,3；1,3,1,3；0,3,0,2；1,3,1,2；0,3,1,2；1,3,0,2；4,6,5,2；等组合。
又例如，以CDM group组合1,0,1,0为例，对应的DMRS端口组合可以是：port 2,0,2,0；2,1,2,1；3,0,3,0；3,1,3,1；2,0,3,0；2,1,3,1；2,0,3,1；2,1,3,0；2,4,6,5；等组合。
在本实施例中，每个时间单元对应的天线端口可以对应同一个CDM group，也可以对应不同的CDM group。如果至少两个时间单元对应的天线端口对应同一个CDM group，这两个时间单元对应的天线端口也可以是不同的。
针对DMRS type 2，除支持和type 1类似的CDM组合，例如以下的至少之一或任意组合：
0,1；1,0；0,0；1,1；
1,0,1；0,0,0；1,1,1；0,1,0；0,1,1；1,0,0；1,1,0；0,0,1；
0,0,0,0；0,0,0,1；0,0,1,0；0,0,1,1；0,1,0,0；0,1,0,1；0,1,1,0；0,1,1,1；1,0,0,0；1,0,0,1；1,1,0,0；1,0,1,0；1,0,1,1；1,1,0,1；1,1,1,0；1,1,1,1；等等。
还可以支持包括CDM group 2在内的相关组合，例如以下的至少之一或任意组合：
0,2；1,2；2,0；2,1；
1,2,1；2,2,2；0,1,2；2,1,2；2,1,1；1,2,2；1,1,2；2,2,1；2,1,0；0,2,0；
0,1,2,0；0,1,2,1；0,1,2,2；0,2,0,2；2,0,2,0；2,1,2,1；等等。
那么相应地，可以增加DMRS端口组合以支持以上CDM group组合。根据TS 38.212中的表7.4.1.1.2-2中CDM group和天线端口的对应关系，CDM group 0中的天线端口编号可以是{0,1,6,7}中的至少一个，CDM group 1中的天线端口编号可以 是{2,3,8,9}中的至少一个，CDM group 2中的天线端口编号可以是{4,5,10,11}中的至少一个。
例如，以CDM group组合1,0为例，对应的DMRS端口组合可以是：port 2,0；2,1；3,0；3,1；6,4等。
又例如，以CDM group组合为0,1,0为例，对应的DMRS端口组合可以是：port 0,2,0；0,3,0；0,2,1；0,3,1；1,2,1；1,3,1；1,2,0；1,3,0；0,2,1；0,3,1；等等。
又例如，以CDM group组合为1,0,1为例，对应的DMRS端口组合可以是：port 2,0,2；2,1,2；2,0,3；2,1,3；3,0,3；3,1,3；3,0,2；3,1,3；等等。
又例如，以CDM group组合0,1,0,1为例，对应的DMRS端口组合可以是：port 0,2,0,2；1,2,1,2；0,3,0,3；1,3,1,3；0,3,0,2；1,3,1,2；0,3,1,2；1,3,0,2；等组合。
又例如，以CDM group组合1,0,1,0为例，对应的DMRS端口组合可以是：port 2,0,2,0；2,1,2,1；3,0,3,0；3,1,3,1；2,0,3,0；2,1,3,1；2,0,3,1；2,1,3,0；等组合。
又例如，以CDM group组合0,1,2为例，对应的DMRS端口组合可以是：port 0,2,4；1,2,4；0,3,4；0,3,5；1,3,5；等组合。
又例如，当配置终端设备进行非时隙级别的重复传输时，可以忽略天线端口与CDM group之间的关联，由此，现有的DMRS表格中的条目也可以用于各个时间单元的天线端口指示，可以最大化地利用现有DMRS表格指示更多的重复样式或调度样式等。例如，DMRS表格中天线端口个数N大于至少一个时间单元个数K的条目均可以用于终端设备的天线端口指示，且天线端口配置信息中所指示的前K个天线端口索引对应于K个时间单元。
在一些实施例中，每个时间单元对应的天线端口可以对应同一个CDM group，也可以对应不同的CDM group。如果至少两个时间单元对应的天线端口对应同一个CDM group，这两个时间单元对应的天线端口也可以是不同的。
值得注意的是，以上端口组合也适用于最大长度为2的情况。以上端口组合既适用于一个码字的情况，也适用于2个码字的情况。如果以上组合仅出现在一个码字的情况下，但是网络设备侧指示共有2个码字，例如每个传输点或cell发送一个码字，共2个，那么每个传输机会的DMRS端口确定依据只有一个码字的情况，即DCI中 指示的DMRS端口组合通过查阅一个码字情况下的端口组合来确定。
在一些实施例中，至少一个时间单元的个数K由网络设备配置或指示；在实际传输次数小于K的情况下，实际传输次数根据天线端口配置信息中的天线端口索引个数N确定，即实际传输次数为天线端口索引个数N。由此，实际传输次数也即占用的时间单元个数可以和预先配置的个数不同，可以通过天线端口配置信息动态地改变，增加了网络设备的调度灵活性。
在一些实施例中，至少一个时间单元的个数K没有被网络设备配置或指示；实际传输次数根据天线端口配置信息中的天线端口索引个数N确定，即实际传输次数为天线端口索引个数N。由此，无需显式地配置重复版本传输次数，也即占用的时间单元个数，由天线端口索引个数N显式地指示，能够节省信令开销。
在一些实施例中，终端设备在天线端口配置信息中所指示的天线端口索引个数N大于至少一个时间单元的个数K的情况下，确定天线端口配置信息所指示的前K个天线端口索引对应于K个时间单元。
例如，天线端口配置信息指示的DMRS天线端口为0,1,2,3，当K＝3时，表示第一个、第二个和第三个传输机会所使用的DMRS端口分别为0,1和2。又例如，当K＝4时，第一个，第二个，第三个和第四个传输机会所使用的DMRS端口分别为0,1,2和3。即一个端口指示信令可以同时支持K取不同值时的端口指示。由此，在DMRS port表格尺寸固定，或者DCI中天线端口指示尺寸固定的情况下，可以使用有限的天线端口组合支持更多的重复样式或更多的网络设备调度样式。
在一些实施例中，可以对Rel-15的DMRS表(可称为第一DMRS表)进行改进以支持重复传输(改进后可称为第二DMRS表)。例如，将以上DMRS端口指示值加入到Rel-15的DMRS表中，使用预留的value或预留的条目(entry)，例如表7.3.1.2.2-1中预留的value 12-15。根据DMRS的配置，例如类型、最大长度等，还可以使用38.212中的表格7.3.1.2.2-2、7.3.1.2.2-3和7.3.1.2.2-4中的预留值和/或预留条目(entry)。
此外，还可以构建一个新的DMRS表(可称为第二DMRS表)专用于重复传输等。例如，当高层信令配置终端设备进行非时隙级别的重复传输，或非时隙级别的TDM传输，或多TRP场景下的重复传输等，新构建的DMRS表格用于确定天线端口配置信息的内容，在其它情况下，使用另外的DMRS表格(例如Rel-15 DMRS表格)来确定天线端口配置信息的内容。
在一些实施例中，以上DMRS端口指示还可以用于确定每个传输机会的TCI状态。例如，在某些情况下，TCI状态指示了每个CDM组对应的TCI状态，而不是每个传输机会对应的TCI状态。通过接收到的DMRS端口指示，终端设备可以确定每个传输机会的DMRS端口，进而可以根据天线端口与CDM group之间的对应关系，确定每个传输机会使用的DMRS端口所在的CDM组，相应地，终端设备可以确定每个传输机会的TCI状态。
例如，以表7.3.1.2.2-1为例，DMRS表中value 9指示的0-2，表示第1个传输机会、第2个传输机会和第3个传输机会所使用的天线端口分别为0、1和2。根据TS38.211中的表7.4.1.1.2-1和7.4.1.1.2-2，终端设备可以获知相应的CDM组编号。例如，以DMRS type 1为例，从表7.4.1.1.2-1中可以获知，0、1和2分别属于CDM group 0、0和1。通过TCI指示，终端设备可以获得CDM group 0和1的TCI状态，进而获知各个传输机会的TCI状态。
在一些实施例中，天线端口配置信息与传输配置指示(TCI)状态配置信息(详细内容请见后面的第三方面的实施例)和/或至少一个时间单元的传输配置信息(详细内容请见后面的第二方面的实施例)联合地被使用。
例如，TCI状态配置信息用于指示每个CDM组的TCI状态，DMRS天线端口配置信息指示用于指示每个传输机会的DMRS端口或CDM组，终端设备可以根据TCI状态配置信息确定DMRS天线端口配置信息所指示的DMRS端口或CDM组对应的TCI状态，进而确定多个传输机会分别对应的TCI状态。
又例如，TCI状态配置信息用于指示每个传输机会的TCI状态，DMRS天线端口配置信息指示用于指示每个传输机会的DMRS端口或CDM组，终端设备可以根据TCI状态配置信息和DMRS天线端口配置信息分别确定多个传输机会的TCI状态和DMRS端口。
以上从终端设备侧进行了示意性说明，以下结合网络设备侧再进行说明，与以上实施例相同的内容不再赘述。
图4是本申请实施例的控制信息的指示方法的另一示意图，如图4所示，该方法包括：
401，网络设备生成天线端口配置信息；以及
402，网络设备向终端设备发送所述天线端口配置信息；所述天线端口配置信息 用于指示至少一个时间单元的发送或接收参数；其中一个时间单元对应至少一个发送或接收参数；
403，终端设备根据天线端口配置信息确定至少一个时间单元的发送或接收参数。
值得注意的是，以上附图4仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图4的记载。
以上各个实施例仅对本申请实施例进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
由上述实施例可知，终端设备接收网络设备发送的天线端口配置信息；以及终端设备至少根据该天线端口配置信息确定至少一个时间单元的发送或接收参数；其中一个时间单元对应至少一个发送或接收参数。由此，网络设备能够对重复传输的不同版本的参数进行指示，从而终端设备能够确定不同版本的参数，避免对重复传输的不同版本错误地进行发送或接收。
第二方面的实施例
本申请实施例提供一种控制信息的指示方法，先从终端设备侧进行说明。图5是本申请实施例的控制信息的指示方法的一示意图，如图5所示，该方法包括：
501，终端设备接收网络设备发送的至少一个时间单元的传输配置信息；以及
502，终端设备根据所述传输配置信息确定至少一个时间单元的发送或接收参数；其中一个时间单元对应至少一个发送或接收参数。
在本申请实施例中，至少一个时间单元用于传输一个传输块(TB，transport block)的相同或不同版本；该至少一个时间单元的传输配置信息配置或指示所述传输块的相同或不同版本的发送或接收参数。该时间单元例如可以是时隙、非时隙(如non-slot,mini-slot或sub-slot)等，但本申请不限于此，例如还可以是一个或多个符号(symbol)等。此外，所述时间单元还可以扩展到其它资源单元上，例如频域单元、空域单元或空间传输层(layer)等。
所述至少一个时间单元的传输配置信息可以是数据信道(例如PDSCH或PUSCH) 的传输配置信息，也可以是控制信道(例如PDCCH或PUCCH)的传输配置信息，本申请不对此做限制。
相应地，本申请实施例还可以应用到所有传输块重复传输的场景下，例如传输块在频域上以TDM的方式进行重复传输，或者传输块在频域上以FDM的方式进行重复传输，或者传输块在空域上以SDM的方式进行重复传输，或者以上至少两种重复方式的组合，例如TDM+FDM，TDM+SDM，FDM+SDM，TDM+FDM+SDM等。
值得注意的是，以上附图5仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图5的记载。
在一些实施例中，发送或接收参数包括如下至少之一：传输点索引，小区索引，传输配置指示(TCI)状态索引，准共址(QCL)信息索引，天线端口索引，CDM组索引，时域资源分配(TDRA)，频域资源分配(FDRA)；但本申请不限于此，还可以是其他的参数。
在一些实施例中，至少一个时间单元的传输配置信息(可称为重复样式，repetition pattern；或者网络设备调度样式的配置信息)至少包括K个发送或接收参数，K为时间单元的个数并且为大于或等于1的正整数。
例如，可以显式地配置或指示重复样式(repetition pattern)。通过配置或指示的repetition pattern，终端设备可以获知每个重复版本与哪个TRP或cell相对应，因而可以正确的使用对应的空间接收参数(spatial RX parameter)对数据信道进行接收。
再例如，repetition pattern可以有如下几种形式：指示与K个repetition相对应的TRP或cell编号，该编号可以是局部的，也可以是全局的，每个编号与一个repetition相对应；或者，指示与K个repetition相对应的TCI状态编号或索引，每个编号与一个repetition相对应；或者，指示与K个repetition相对应的天线端口或CDM组编号，每个编号与一个repetition相对应；或者，指示K个repetition相对应的时域或频域资源分配(例如DCI中的TDRA或FDRA域)，每个资源分配表示一个repetition对应的资源分配。
例如，重复次数是K，那么一个重复样式由K次重复相关参数组成，例如可以 是如下形式：发送第一次重复传输的TRP或cell编号，发送第二次重复传输的TRP或cell编号，……，发送第K次重复传输的TRP或cell编号。例如当K等于4时，一个样式可以是：cell 1，cell 2，cell 1，cell 2。由此，可以直接地指示给终端设备多个传输机会发送的数据是来自不同的cell的，终端设备需要使用不同的接收参数(如每个cell对应的天线端口、TCI状态等)去接收数据。
或者，发送第一次重复传输所使用的TCI状态，发送第二次重复传输所使用的TCI状态，……，发送第K次重复传输所使用的TCI状态。例如，当K＝3时，一个样式可以是：TCI state 1，TCI state 3，TCI state 3。由此，可以直接地指示终端设备：网络设备在多个传输机会的所使用的TCI状态，进而终端设备可以使用相应的接收滤波器来接收数据。
或者，发送第一次重复传输所使用的DMRS天线端口，发送第二次重复传输所使用的DMRS天线端口，……，发送第K次重复传输所使用的DMRS天线端口。例如，当K＝4时，一个样式可以是：端口2，端口0，端口0，端口2。由此，可以直接地指示终端设备：网络设备在多个传输机会时所使用的天线端口的情况，进而终端设备可以在相应端口对应的时频资源上，使用对应的接收滤波器来接收DMRS。
或者，发送第一次重复传输所使用的DMRS CDM group编号，发送第二次重复传输所使用的DMRS CDM group编号，……，发送第K次重复传输所使用的DMRS CDM group编号。例如，当K＝2时，一个样式可以是：CDM group 0，CDM group 1。由此，可以间接地指示终端设备：网络设备在多个传输机会时所使用的TCI状态，进而终端设备可以使用相应的接收滤波器来接收数据。
或者，第一次重复传输的时域或频域资源分配信息，第二次重复传输的时域或频域资源分配信息，……，第K次重复传输的时域或频域资源分配信息。例如，当K＝3时，一个样式可以是SLIV 1，SLIV 2，SLIV 3或者RIV 1，RIV 2，RIV 3。由此，可以直接地指示终端设备：网络设备在多个传输机会时所使用的时频域资源，进而终端设备可以在相应地资源上来接收数据。
在一些实施例中，至少一个时间单元的传输配置信息由如下至少之一的信令配置和/或激活：无线资源控制(RRC)信令、介质访问控制(MAC)控制元素(CE)，下行控制信息(DCI)。
例如，以上所述重复样式可以通过RRC信令配置，也可以先由RRC信令配置， 然后由MAC-CE信令激活，还可以先由RRC信令配置，然后由MAC-CE信令激活，再由DCI信令指示，还可以先由RRC信令配置，再由DCI信令指示。
在一些实施例中，至少一个时间单元的传输配置信息被预先定义，或者与已配置参数或已指示参数相关联。
例如，可以通过协议预先定义一种重复样式；还可以根据配置或指示的参数确定其中一种或以上的重复样式，例如，通过DCI当中的某个域(例如TDRA或FDRA域或天线端口指示域或冗余版本指示域，等)来与重复样式关联，即通过这些域来隐式地指示所使用的重复样式。
在一些实施例中，至少一个时间单元的传输配置信息包括在控制信息的一个信息域中，或者与控制信息的信息域联合地被编码和传输。
在一些实施例中，至少一个时间单元的传输配置信息(重复样式)与传输配置指示(TCI)状态配置信息(详细内容请见后面的第三方面的实施例)和/或天线端口配置信息(详细内容请见第一方面的实施例)联合地被使用。
例如，TCI状态配置信息用于指示每个CDM组的TCI状态，重复样式用于指示每个传输机会的DMRS端口或CDM组，终端设备可以根据TCI状态配置信息确定重复样式指示的DMRS端口或CDM组所对应的TCI状态，进而确定多个传输机会分别对应的TCI状态。
又例如，TCI状态配置信息用于指示每个传输机会的TCI状态，重复样式用于指示每个传输机会的DMRS端口或CDM组，终端设备可以根据TCI状态配置信息和重复样式分别确定多个传输机会的TCI状态和DMRS端口。
以上从终端设备侧进行了示意性说明，以下结合网络设备侧再进行说明，与以上实施例相同的内容不再赘述。
图6是本申请实施例的控制信息的指示方法的另一示意图，如图6所示，该方法包括：
601，网络设备生成至少一个时间单元的传输配置信息；以及
602，网络设备向终端设备发送所述传输配置信息；所述传输配置信息用于指示至少一个时间单元的发送或接收参数；其中一个时间单元对应至少一个发送或接收参数；
603，终端设备根据该传输配置信息确定至少一个时间单元的发送或接收参数。
值得注意的是，以上附图6仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图6的记载。
以上各个实施例仅对本申请实施例进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
由上述实施例可知，终端设备接收网络设备发送的至少一个时间单元的传输配置信息；以及终端设备至少根据该传输配置信息确定至少一个时间单元的发送或接收参数；其中一个时间单元对应至少一个发送或接收参数。由此，网络设备能够对重复传输的不同版本的参数进行指示，从而终端设备能够确定不同版本的参数，避免对重复传输的不同版本错误地进行发送或接收。
第三方面的实施例
本申请实施例提供一种控制信息的指示方法，先从终端设备侧进行说明。图7是本申请实施例的控制信息的指示方法的一示意图，如图7所示，该方法包括：
701，终端设备接收网络设备发送的传输配置指示(TCI)状态配置信息；以及
702，终端设备根据所述传输配置指示(TCI)状态配置信息确定至少一个时间单元的发送或接收参数；其中一个时间单元对应至少一个发送或接收参数。
在本申请实施例中，至少一个时间单元用于传输一个传输块(TB，transport block)的相同或不同版本；传输配置指示(TCI)状态配置信息配置或指示所述传输块的相同或不同版本的发送或接收参数。该时间单元例如可以是时隙、非时隙(例如non-slot，mini-slot，sub-slot)等，但本申请不限于此，例如还可以是一个或多个符号(symbol)等。此外，所述时间单元还可以扩展到其它资源单元上，例如频域单元、空域单元或空间传输层(layer)等。
所述传输配置指示(TCI)状态配置信息可以是数据信道(例如PDSCH或PUSCH)的传输配置指示(TCI)状态配置信息，也可以是控制信道(例如PDCCH或PUCCH)的传输配置指示(TCI)状态配置信息，本申请不对此做限制。
相应地，本申请实施例还可以应用到所有传输块重复传输的场景下，例如传输块 在频域上以TDM的方式进行重复传输，或者传输块在频域上以FDM的方式进行重复传输，或者传输块在空域上以SDM的方式进行重复传输，或者以上至少两种重复方式的组合，例如TDM+FDM，TDM+SDM，FDM+SDM，TDM+FDM+SDM等。
值得注意的是，以上附图7仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图7的记载。
在一些实施例中，发送或接收参数包括如下至少之一：传输点索引，小区索引，传输配置指示(TCI)状态索引，准共址(QCL)信息索引，天线端口索引，CDM组索引，时域资源分配(TDRA)，频域资源分配(FDRA)；但本申请不限于此，还可以是其他的参数。
在一些实施例中，传输配置指示(TCI)状态配置信息指示至少一个时间单元的TCI状态，或者传输配置指示(TCI)状态配置信息指示至少一个CDM group的TCI状态。
在一些实施例中，传输配置指示(TCI)状态配置信息指示至少一个时间单元的TCI状态；并且终端设备确定天线端口配置信息指示的天线端口所对应的CDM组与TCI状态无关。
例如，为了正确地指示一个或以上传输机会的TCI状态，令DCI中的‘Transmission configuration indication’域(field)指示每个传输机会的TCI状态，相当于DCI中一个code point可以包含多个TCI状态(例如，多于2)。在这种情况下，终端设备可以根据TCI域的指示直接确定每个传输机会的TCI状态。此时，TCI域指示的TCI状态与CDM group的TCI状态是没有关联的。由此，终端设备可以根据TCI指示直接获得每个传输机会或至少一个时间单元的TCI状态，无需借助DMRS天线端口及其对应的CDM group的TCI状态间接获得每个传输机会或至少一个时间单元的TCI状态，算法复杂度低。
在一些实施例中，传输配置指示(TCI)状态配置信息与天线端口配置信息(详细内容请见第一方面的实施例)和/或至少一个时间单元的传输配置信息(详细内容请见第二方面的实施例)联合地被使用来指示至少一个时间单元的发送或接收参数。
在一些实施例中，终端设备期望天线端口配置信息指示的天线端口个数大于或等于至少一个时间单元的个数K；或者也可以说，终端设备确定(认为、默认)天线端口配置信息指示的天线端口个数大于或等于至少一个时间单元的个数K。
例如，使用DMRS天线端口配置信息来指示每个传输机会对应的天线端口，TCI状态配置信息来指示每个传输机会的TCI状态，终端设备可以根据DMRS天线端口配置信息和TCI状态配置信息分别确定多个传输机会的DMRS端口和TCI状态。
在这个例子里，可以忽略指示的DMRS端口或TCI状态与CDM group之间的关联，即可以忽略DMRS端口和CDM group的关联，或者忽略TCI状态配置信息中指示的TCI状态和CDM group的关联，而是直接建立DMRS端口和TCI状态之间的关联。因此，DMRS表中，只要包含的DMRS端口数大于或等于K的条目(entry)均可以用于DMRS天线端口配置信息的指示。
终端设备期望天线端口配置信息指示的DMRS端口数大于或等于K，或者DMRS表中DMRS端口数大于或等于传输机会个数的条目(entry)才会生效，才可以用于终端设备的天线端口配置信息指示。终端设备在收到DMRS天线端口配置信息后，确定天线端口配置信息中指示的天线端口中的前K个天线端口分别对应K个传输机会的天线端口。
在一些实施例中，终端设备不期望天线端口配置信息指示的天线端口所对应的CDM组个数或集合与至少一个时间单元的传输配置信息所指示的CDM组个数或集合不一致。或者也可以说，终端设备确定(认为、默认)天线端口配置信息指示的天线端口所对应的CDM组个数或集合与至少一个时间单元的传输配置信息(重复样式)所指示的CDM组个数或集合一致。
例如，至少一个时间单元的传输配置信息(重复样式)用于指示每个传输机会对应的发送或接收参数，根据指示的参数可以确定每个传输机会对应的天线端口所在的CDM组，此外根据DMRS天线端口配置信息指示的至少一个时间单元的端口集合，终端设备可以推算出每个传输机会对应的天线端口。
例如至少一个时间单元的个数为K＝4，至少一个时间单元的传输配置信息指示的参数为CDM组编号，且CDM组编号为0,1,1,0，DMRS天线端口配置信息指示的天线端口为Table 7.3.1.2.2-1中的value 7，即0,2。因为port 0属于CDM group 0，port 2属于CDM group 1，终端设备就可以确定K个传输机会的DMRS port分别为0,2,2, 0。
在这种情况下，终端设备不期望DMRS天线端口配置信息指示的DMRS端口对应的CDM组个数或集合与至少一个时间单元的传输配置信息(重复样式)所指示的CDM组的个数或集合不一致。终端设备也不期望DMRS表中指示的两个或以上DMRS端口属于同一个CDM组。由此，终端设备在判断每个CDM组或每个时间单元对应的天线端口时不会造成模糊。
在一些实施例中，传输配置指示(TCI)状态配置信息包括在控制信息的一个信息域中，或者与控制信息的信息域联合地被编码和传输。
以上从终端设备侧进行了示意性说明，以下结合网络设备侧再进行说明，与以上实施例相同的内容不再赘述。
图8是本申请实施例的控制信息的指示方法的另一示意图，如图8所示，该方法包括：
801，网络设备生成TCI状态配置信息；以及
802，网络设备向终端设备发送TCI状态配置信息；所述TCI状态配置信息用于指示至少一个时间单元的发送或接收参数；其中一个时间单元对应至少一个发送或接收参数；
803，终端设备根据TCI状态配置信息确定至少一个时间单元的发送或接收参数。
值得注意的是，以上附图8仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图8的记载。
以上各个实施例仅对本申请实施例进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
由上述实施例可知，终端设备接收网络设备发送的TCI状态配置信息；以及终端设备至少根据该TCI状态配置信息确定至少一个时间单元的发送或接收参数；其中一个时间单元对应至少一个发送或接收参数。由此，网络设备能够对重复传输的不同版本的参数进行指示，从而终端设备能够确定不同版本的参数，避免对重复传输的不同版本错误地进行发送或接收。
