Description

终端、网络设备和通信方法
本申请要求于2017年02月04日提交中国专利局、申请号为201710064511.3、申请名称为“终端、网络设备和通信方法”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
本申请涉及通信领域，并且更具体地，涉及终端、网络设备和通信方法。
背景技术
随着通信技术的发展，在新无线(new radio，NR)通信技术中，高频段的频谱资源的应用成为实现大数据速率通信的一种有效方式。
在高频段上，为克服高频段的路径衰落，增加覆盖，网络设备和终端通常采用波束的方式进行通信。即网络设备或者终端，对自身的多个天线阵元进行模拟加权，使加权后形成的信号能量在某个方向增强，在该方向上向对端发送信号或者接收对端发送的信号。
在实际应用中，终端可以采用波束的方式向网络设备发送上行数据信道。进一步地，终端可以在该上行数据信道上传输上行控制信息。
因为高频通信本身的波长较短，所以信号的绕射能力较差，容易受到遮挡物的影响。当上行的控制信息在波束上传输的时候，就会发生因为遮挡导致的链路质量下降，从而降低了控制信息传输的可靠性。
终端采用波束的方式，如何在上行数据信道上可靠地传输上行控制信息是目前一个待解决的问题。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
可以应用本申请实施例的通信方法的通信系统的示例性结构图如图1所示。应理解，本申请实施例并不限于图1所示的系统架构中，此外，图1中的装置可以是硬件，也可以是从功能上划分的软件或者以上二者的结合。
从图1可知，可以应用本申请实施例的通信方法的通信系统可以包括网络设备110和终端120。
网络设备110可以是基站。应理解，本申请实施例对基站的具体类型不作限定。采用不同无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同。为方便描述，本申请所有实施例中，上述为终端提供无线通信功能的装置统称为基站，例如未来网络中的基站设备、小基站设备(pico)等。
网络设备可以为具有无线收发功能的设备或可设置于该设备的芯片，该设备包括但不限于：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 and reception point，TRP或者transmission point，TP)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(DU，distributed unit)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层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU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RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
终端120可以是用户设备(user equipment，UE)。UE可以经无线接入网(radio access network，RAN)与一个或多个核心网(core network)进行通信。UE可称为接入终端、终端设备、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、无线通信设备、用户代理或用户装置。UE可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设 备或连接到无线调制解调器的其它设备、车载设备、可穿戴设备或物联网、车辆网中的终端设备以及未来网络中的任意形态的终端设备等。
本申请实施例既可以应用在传统的典型网络中，也可以应用在未来的以UE为中心(UE-centric)的网络中。UE-centric网络引入无小区(Non-cell)的网络架构，即在某个特定的区域内部署大量小站，构成一个超级小区(Hyper cell)，每个小站为Hyper cell的一个传输点(Transmission Point,TP)或TRP，并与一个集中控制器(controller)相连。当UE在Hyper cell内移动时，网络侧设备时时为UE选择新的sub-cluster(子簇)为其服务，从而避免真正的小区切换，实现UE业务的连续性。其中，网络侧设备包括无线网络设备。或者是，在以UE为中心的网络中，多个网络侧设备，如小站，可以有独立的控制器，如分布式控制器，各小站能够独立调度用户，小站之间在长期上存在交互信息，使得在为UE提供协作服务时，也能够有一定的灵活性。
本申请实施例中不同基站可以为具有不同的标识的基站，也可以为具有相同的标识的被部署在不同地理位置的基站。由于在基站被部署前，基站并不会知道其是否会涉及本申请实施例所应用的场景，因而，基站，或基带芯片，都应在部署前就支持本申请实施例所提供的方法。可以理解的是，前述具有不同标识的基站可以为基站标识，也可以为小区标识或者其他标识。
本申请实施例中部分场景以无线通信网络中NR网络的场景为例进行说明，应当指出的是，本申请实施例中的方案还可以应用于其他无线通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。在图1所示的通信系统下，网络设备110和终端120间可以采用波束的方式在高频段的资源上相互传输数据。
高频段的波长较短，使得天线间距可以缩小，从而在同样的面积上可以放置更多的天线阵元。大量的天线阵元可以形成大规模的阵列天线，大规模的阵列天线可以通过波束赋形带来阵列增益，从而有效增加覆盖，克服高频段的路径衰减。
对大规模的天线阵列而言，从成本的角度考虑，无法实现每一个天线阵元都连接一个射频通道。在有限个射频通道的条件下，通过在射频端采用移相器，可以在射频端实现模拟相位的加权，从而在射频端形成了模拟波束。
模拟波束可以在网络设备形成，也可以在终端形成。网络设备或终端可以通过改变天线阵元的相位权重，增强某个方向上信号的能量，使得其在该方向上可以更好地接收或发送信号。可以将该方向上增强了能量的信号或在该方向上发送增强了能量的信号天线端口称为波束，也就是说，网络设备或终端可以向不同的方向发送波束，或接收不同方向的波束。
对高频段而言，可以采用模拟波束，或者模拟和数字混合加权的方式，以满足覆盖需求。
如果采用模拟波束或混合波束的方式进行通信，则对于同一个天线面板而言，采用多个波束上发送信息时，这多个波束采用时分发送的方式。也就是说，如果采用模拟波束或混合波束的方式进行通信，则对于同一个天线面板而言，同一个时间只能形成一个模拟波束，指向一个方向，即覆盖某一个区域。
如：网络设备110和终端120上可以设置大量的天线阵元，在终端120向网络设备110发送信息时(如上行数据信息或上行控制信息)时，终端120可以在自身的射频端设 置移相器，通过移相器改变天线阵元的相位权重，实现对多个天线阵元的模拟相位加权，增强网络设备方向上的信号的能力，形成一个对准网络设备120的模拟波束，并通过该模拟波束网络设备110发送信息。
对应的，网络设备也可以在自身的射频端设置移相器，通过该移相器改变天线阵元的相位权重，实现对多个天线阵元的模拟相位加权，形成一个接收波束来接收终端120发送的信息。
同理，作为上行传输的逆过程，在网络设备向终端120发送信息(即下行数据信息或下行控制信息)时，也可以采用上述的通信方式，在此不再重复赘述。
本申请的实施例中，波束可以理解为一种空间资源。不同的波束可以认为是不同的空间资源。与LTE中的波束不同，本申请实施例中的波束主要是模拟波束，即一个天线面板上同一时间只能形成一个模拟波束，如果终端或网络设备只有1个天线面板，在需要多波束发送的时候，不同的波束只能采取时分的方式。
本申请的技术方案不仅可以适用于利用不同波束进行传输的场景，也可以适用于利用不同端口资源进行传输的场景。因为端口本身是一种逻辑的资源标识，可以用来区分不同的空间资源，也就可以用来区分不同的波束。
在本申请中，不同的空间资源可以具有不同的准共址(quasi-co-located，QCL)信息。QCL信息一般用于指示参考信号端口之间的关系。采用波束的通信方式中，采用上行波束进行数据传输之前，需要进行波束的配对扫描，终端需要发送上行参考信号进行波束的扫描，以确定终端发送数据时采用的发送波束和网络设备采用的接收波束。该参考信号可以是探测参考信号(sounding reference signal,SRS)信号，或者其他的参考信号，当终端的基于波束的对应性或互易性存在时，该参考信号也可以是某个下行的参考信号。互易性是指终端的上行的波束可以根据下行的扫描结果来确定，即终端通过下行波束扫描确定的最优的接收波束，就对应上行最优的发送波束。
本申请中的QCL信息可以是对空间关系进行描述的一种参数，比如离开角(angle-of-departure，AOD)或者发送波束天线的空间相关性。在实际采用某个波束进行数据通信时，如果终端获得了QCL信息，则可以通过QCL信息来确定对应的发送波束，比如通过确定物理上行共享信道(physical uplink shared channel，PUSCH)或物理上行控制信道(physical uplink control channel，PUCCH)的解调参考信号(demodulation reference signal,DMRS)的端口同之前扫描时的SRS的端口是QCL的，也就是说PUSCH或PUCCH的波束方向和之前的某个SRS的波束方向是相同的。在本申请中，当需要采用多个波束进行发送的时候，需要采用不同方向的波束，因此，不同的波束就具有不同的QCL信息。
两个天线端口之间具有准共址(quasi co-located，QCL)关系，指的是，一个天线端口的信道大尺度参数可以通过另一个天线端口得到的(conveyed)信道大尺度参数而推知(infer)。大尺度参数可以包括平均增益(average gain)，平均时延(average delay)，时延扩展(delay spread)，多普勒频移(Doppler shift)，多普勒扩展(Doppler spread)，空间参数(spatial parameter，或spatial Rx parameters)中的一项或多项。
其中，空间参数可以包括到达角(angle of arrival，AOA)、主到达角(dominant AoA)、平均到达角(average AoA)、出发角(angle of departure，AOD)、信道相关矩阵，到达角的功率角度扩展谱，平均出发角(average AoD)、出发角的功率角度扩展谱、发射信 道相关性、接收信道相关性、发射波束成型、接收波束成型、空间信道相关性、空间滤波器，或，空间滤波参数，或，空间接收参数，或，权值信息等中的一项或多项。
需要说明的是，图1仅为示例图，其中网络设备110和终端120的个数对本申请提供的方案不构成限定。在实际应用中，可以以不同图1所示的个数进行网络部署。
此外，本申请提供的方案还可以适用于除图1之外的其他任一采用波束的方式进行通信的通信系统中，本申请实施例对此不进行限定。
图12示出了本申请实施例的一种可能的应用环境。图12所示的基站可以是5G中的基站。具体地，在5G系统中，基站可以进行集中式单元(Central Unit,CU)和分布式单元(distributed unit,DU)分离，或者说协议栈分离。换句话说，CU和DU可以处理不同的协议层。CU和DU之间可以存在通信连接，以互相传递相关协议层的信息。例如，作为一种可能的方案，DU可以处理无线链路层控制(Radio Link Control，RLC)协议及以下的协议，CU可以处理RLC层以上的协议。例如，CU可以处理分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)或无线资源控制(Radio Resource Control,RRC)协议。DU可以用于处理物理层(Physical Layer,PHY)协议、媒体接入控制层(Media Access Control，MAC)协议和RLC协议。同一个CU可以与一个或多个DU连接，同一个DU可以包括一个或多个小区。可选地，CU和DU可以合称为gNB。
本申请下面实施例仅以图1所示的通信系统为例，对本申请提供的通信方法、网络设备和终端进行说明。
图2是本申请一个实施例的通信方法的示意性流程图。应理解，图2示出了通信方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图2中的各个操作的变形。此外，图2中的各个步骤可以按照与图2呈现的不同的顺序来执行，并且有可能并非要执行图2中的全部操作。
S220，终端使用第一空间资源集合中的多个空间资源，发送第一上行控制信息。相应地，网络设备接收该第一上行控制信息。
其中，该第一空间资源集合可以是终端上预先配置的。具体地，终端和网络设备上均可以配置有第一空间资源集合，其中，第一空间资源集合可以包括多个空间资源的索引或标识信息。
该通信方法中，终端使用多个空间资源发送第一上行控制信息，当其中部分空间资源上传输的上行控制信息受影响时，其他空间资源依然可以传输上行控制信息，从而可以提高上行控制信息的传输可靠性，最终可以提高终端与网络设备之间的通信可靠性。
本申请实施例中的空间资源可以是波束。此时第一空间资源集合可以理解为第一波束集合；第一空间资源集合包括多个空间资源，可以理解为：第一空间资源集合包括多个波束。其中，每个波束有对应的模拟相位加权值。
本申请实施例中以下内容均以空间资源为波束为例，进一步详述本申请实施例的通信方法。应理解，以下内容中的波束均可以替换成端口或与波束有相同含义的其他名称。
网络设备可以将网络设备与终端之间通信质量(如RSRP值)较好或空间相关性小的多个波束确定为第一波束集合，具体可以是将终端可以采用的波束中通信质量较好或相关性较小的多个波束确定为第一波束集合。或者，每个波束可以是网络设备与终端之间已经配好对的收发波束中的波束。
即第一波束集合中的波束的通信质量可以优于网络设备与终端之间通信可以使用的其他波束的通信质量。
如，网络设备与该终端之间可以通过5个波束通信，但其中3个波束的质量比其他2个波束的质量好，则网络设备可以将这3个波束确定为第一波束集合。
终端使用通信质量较好的波束发送第一上行控制信息，可以进一步提高终端与网络设备之间的通信可靠性。
第一上行控制信息可以包括一种或多种信息。
当第一上行控制信息包括多种信息时，表示多种信息的波束集合相同，均为第一波束集合。
第一上行控制信息可以包括波束标识(beam index，BI)。如网络设备下发测量参考信号、终端测量参考信号后，可以通过该BI向网络设备上报究竟哪些波束的质量更好，以利于网络设备根据测量的结果进行波束的调度。
第一上行控制信息可以包括波束修复请求(recovery request，RR)消息。高频通信系统中采用波束通信时，波束受到影响，如被遮挡导致波束中断时，终端可以通过RR消息通知网络设备通信已经中断。网络设备收到RR消息后，会采取一定的措施，比如切换波束等，进行通信的修复。
第一上行控制信息可以包括波束的参考信号接收功率(reference signal receiving power，RSRP)。
第一上行控制信息还可以包括以下至少一种信息：混合自动重传请求(hybrid auto retransmission request-acknowledgement，HARQ-ACK)、秩指示(rank indicator，RI)、信道质量指示(channel quality indicator，CQI)和预编码矩阵索引(precoding matrix index，PMI)。RI、HARQ-ACK、CQI、PMI和RSRP的定义可以参考LTE技术中相同或相似术语的定义，为了简洁，此处不再赘述。
其中，终端可以使用第一空间资源集合中的多个空间资源，在上行数据信道上发送第一上行控制信息。
图2所示的通信方法中，可选地，第一控制资源集合中的多个资源可以不是终端上预先配置的。此时，图2所示的通信方法还可以包括：S210，网络设备发送第一指示信息，该第一指示信息用于指示第一空间资源集合，该第一空间资源集合包括多个空间资源。相应地，终端接收该第一指示信息。相应地，终端接收第一指示信息。
第一上行控制信息包括多种信息时，网络设备通过一个第一指示信息指示终端发送多种信息时的波束集合，可以节省信令，即节省通信资源。
第一指示信息可以包括第一上行控制信息中每种信息的索引和第一波束集合中每个波束的索引或每个波束所属的波束对的索引或每个波束所属的波束组的索引。通过索引指示信息和波束，可以节省信令开销，从而可以节省通信资源。
第一指示信息还可以包括QCL相关的信息，所述QCL相关的信息是用于指示端口之间的关于某个空间参数的是相似的。如果终端能够获得端口之间的关于某个空间参数是相似的，则两个端口具有相似的空间特性。
在本申请中，为了指示终端采用不同的发送波束，可以通过在第一指示信息中，携带PUCCH或PUSCH的DMRS端口同SRS的端口之间关于某个参数是QCL的信息。所述 QCL参数可以是AOA，或者发送天线的空间相关性。这样，就可以实现在不同的波束上发送控制信息。网络设备可以通过高层信令发送第一指示信息。相应地，终端可以通过高层信令接收第一指示信息。
高层信令可以包括有无线资源控制(radio resource control，RRC)信令和媒体接入控制-控制单元(medium access control-control element，MAC-CE)信令。
网络设备可以通过下行控制信息发送第一指示信息，相应地，终端可以通过下行控制信息接收第一指示信息。
图2所示的通信方法中，可选地，第一控制资源集合中的多个资源可以不是终端上预先配置的。此时，图2所示的通信方法中还可以包括：网络设备发送下行调度信息，所述下行调度信息包括多个时间单元的调制编码方式。相应地，终端接收该下行调度信息。终端接收下行调度信息后，可以确定该多个时间单元中满足某个条件的调制编码方式，如大于某个阈值的调制编码方式，并确定该多个时间单元内采用该调制编码方式值的传输块所对应的波束组成第一波束集合
也就是说，S220中所述的第一波束集合中的波束为传输第一传输块时使用的波束，第一传输块的调制编码方式为上述多个时间单元的调制编码方式中满足第一条件的调制编码方式。
本申请实施例中，终端使用多个时间单元中调制编码方式值满足第一条件的传输块对应的波束发送第一上行控制信息，可以进一步提高第一上行控制信息的通信可靠性。
第一条件可以是终端上预先配置的，如可以是根据通信标准配置的，也可以是根据网络设备发送的配置信息配置的。
第一条件具体可以是调制编码方式值最高，即第一传输块的调制编码方式值在上述多个时间单元的调制编码方式中最高。
其中，一个时间单元可以是一个子帧，也就是说下行调度信息中包括的可以是多个子帧的调制编码方式。应理解，每个子帧的调制编码方式可以是多个。
如图3所示的两个子帧中，每个子帧包括7个符号，第一个子帧为双向子帧，第二个子帧为全上行子帧，第一个子帧的下行符号携带有这两个子帧的调度信息。
此时，终端可以在第一个下行子帧的调度信息中收到这两个子帧所采用的调制编码方式信息。然后，终端可以判断这两个子帧中哪个子帧的调制编码方式较大，并通过采用该较大调制编码方式的传输块对应的波束发送第一上行控制信息。
终端上可以预先配置，如按照标准配置如下信息：当值最高的调制编码方式有多个，即调制编码方式最高的传输块有多个时，可以使用与调制编码方式值最高的传输块对应的波束中、时间最靠前的波束发送第一上行控制信息。
当每个时间单元不是集中调度时，则需要指示发送第一上行控制信息时的第一波束集合。如图4所示，包含有2个子帧，每个子帧为7个符号，其中每个子帧都包含有自己的调度信息，所以，当网络设备在多个子帧上调度终端的上行数据信道时，可以向终端发送指示信息，指示第一上行控制信息会在哪个子帧上传输。
图2所示的通信方法或该通信方法的各种可能的实现方式中，第一波束集合可以是第二波束集合的子集。其中，该第二波束集合包括的是终端发送第二上行控制信息时可以使用的多个波束，第二上行控制信息与第一上行控制信息是不同类型的信息。
如第二上行控制信息可以包括HARQ-ACK、RR、RI、BI和RSRP中至少一种；第一上行控制信息可以包括BI、RSRP、CQI和PMI中除第一上行控制信息中包括的信息之余的至少一种。
第二波束集合中包括的多个波束可以用于发送第二上行控制信息这一信息，可以是终端上配置的，也可以是网络设备指示的。若是网络设备指示的，则图2所示的通信方法或该通信方法的各种可能的实现方式中，还可也包括：网络设备发送第二指示信息，第二指示信息用于指示终端发送第二上行控制信息时的第二波束集合。相应地，终端接收该第二指示信息。
其中，第二上行控制信息中各种信息的重要度可以高于第一上行控制信息中各种信息的重要度。换句话说，第二上行控制信息中各种信息对终端与网络设备之间的通信的影响，比第一上行控制信息中各种信息对终端与网络设备之间的通信的影响大。
此时，第二波束集合包括的波束更多，即终端可以使用更多的波束发送重要度高的第二上行控制信息，从而可以提高第二上行控制信息的通信可靠性。第一波束集合包括的波束更少，即终端可以使用更少的波束发送重要度低的第一上行控制信息，从而可以节省通信资源。
网络设备可以通过高层信令发送第二指示信息。相应地，终端可以通过高层信令接收第二指示信息。
高层信令可以包括有RRC信令和媒体接入控制-控制单元(medium access control-control element，MAC-CE)信令。
网络设备可以通过下行控制信息发送第二指示信息，相应地，终端可以通过下行控制信息接收第二指示信息。
第二上行控制信息可以包括一种或多种信息。
当第二上行控制信息包括多种信息时，表示多种信息的波束集合相同，均为第二波束集合。也就是说，网络设备可以通过一个第二指示信息指示终端发送多种信息时的波束集合，从而可以节省信令，即节省通信资源。
第二指示信息可以包括第二上行控制信息中每种信息的索引和第二波束集合中每个波束的索引或每个波束所属的波束对的索引或每个波束所属的波束组的索引。通过索引指示信息和波束，可以节省信令开销，从而可以节省通信资源。
图2所示的通信方法或该通信方法的各种可能的实现方式中，终端使用第一波束集合中的多个波束，在上行数据信道发送第一上行控制信息时，终端可以根据第一上行控制信息包括的信息的资源映射优先级对第一上行控制信息进行时域资源映射。
在此之前，终端可以获取资源映射优先级和/或资源映射方式。然后根据资源映射优先级和资源映射方式对第一上行控制信息进行时域资源映射。
该资源映射方式和/或该资源映射优先级可以根据通信标准配置的，也可以是从网络设备接收的。
时域资源具体可以为时域符号。此时，资源映射方式可以包括：若信息的资源映射优先级越高，则该信息的目标时域符号相对于参考信号的时域符号的符号距离越小，反之越大；若信息的资源映射优先级越高，则该信息的目标时域符号位于参考信号的时域符号之前，反之在后。
或者，资源映射方式可以包括：若信息的资源映射优先级越低，该信息在较少时域符号上传输时，或者与优先级较高的信息在映射时发生冲突时，则低优先级的信息最先被丢弃，反之最后被丢弃。或者预定义在上行时域符号较少的资源上，仅映射优先级高的信息，而在较大的资源上，可以映射高优先级和低优先级的信息。
如，当参考信号为解调参考信号(demodulation reference signal，DMRS)，DMRS占用最前面的时域符号，资源映射优先级为(HARQ-ACK和RR)>(RI、BI和RSRP)>(CQI和PMI)>数据(Data)的资源时，根据前述的资源映射方式得到的一个资源映射示意图如图5所示。
应理解，上述资源映射优先级只是一个示例，不应对本申请实施例构成限制。本申请实施例中，可以使用其他的资源映射优先级，如(HARQ-ACK和RR)>(RI)>(BI、RSRP、CQI和PMI)>数据(Data)。
如图5中所示，HARQ-ACK和RR的目标时域符号紧靠DMRS的时域符号放置；RI和BI的目标时域符号在DMRS的时域符号后的第二个时域符号上；RSRP的目标时域符号在DMRS的时域符号后的第4、5个符号上，CQI和PMI的目标时域符号在RSRP的目标时域符号之后，此后的时域符号是数据可以占用的时域符号。其中每个时域符号上的信息采用频分的方式处理。
当基准信号为DMRS，DMRS占用子帧中的第二个符号，资源映射优先级为(HARQ-ACK和RR)>(RI、BI和RSRP)>(CQI和PMI)>数据(Data)的资源时，根据前述的资源映射方式得到的一个资源映射示意图如图6所示。
如图6所示，(HARQ-ACK和RR)的目标时域符号为第一个时域符号，RI和BI的目标时域符号为第三个时域符号，RSRP的目标时域符号为第4、5个符号，CQI和PMI的目标时域符号在RSRP的目标时域符号之后，此后的时域符号是数据可以占用的时域符号。
图6介绍的是一个子帧有1个DMRS的情况。当支持时隙(slot)或者微时隙(mini-slot)聚合的情况下，每个slot和mini-slot可以有自己的DMRS。此时，可以在多个slot或者minislot上统一进行资源映射。
当基准信号为DMRS，DMRS占用子帧中的第二个符号，资源映射优先级为(HARQ-ACK和RR)>(RI、BI和RSRP)>(CQI和PMI)>数据(Data)的资源时，根据前述的资源映射方式，在多个slot或者minislot上统一进行资源映射的示意图如图7所示。
如图7所示，ACK和RR的目标时域符号可以在第一个slot或者mini-slot的DMRS占用的时域符号附近，RI、CRI和BI的目标时域符号可以在第二个slot或者mini-slot的DMRS占用的时域符号附近。
终端使用第二波束集合中的多个波束发送第二上行控制信息时，也可以根据资源映射优先级对第二上行控制信息进行资源映射，具体实现方式可以参考第一上行控制信息的实现方式，为了简洁，此处不再赘述。
下面介绍几种时隙(slot)的发送方法。
其中，一种slot的发送方法可以包括：网络设备向终端发送一个传输块(transmission block,TB)的数据时，在经过码块分割、信道编码、速率匹配、码块级联之后，可以使用 现有技术按照分配的调制编码方式(modulation and coding scheme，MCS)对生成的比特数进行调制。该方法与现有技术不同之处在于，将生成的比特数按照不同的调制方式进行分别调制。对比特数采用不同调制方式的一种简单方式就是均匀划分，然后分别按照不同的调制方式，生成对应的调制符号数。在资源映射之前，还可以考虑进行调制符号的交织。
所述交织方式中，如果mini-slot包含有多个时域符号，而且所传输的内容对时延没有要求，则可以采用跨时域符号的交织方式对调制符号进行交织；如果所传输的内容对时延没有要求，则可以采用每个时域符号内部的交织方式对调制符号进行交织。最后进行资源的映射。
对应的，终端在接收数据时，首先根据调度信令中的下行控制信息(downlink control information,DCI)中的reference MCS和MCS的偏移量，将接收到的符号进行解调，得到对应的比特。然后会根据该信令中的reference MCS，确定对应的TB size(TB块的大小)，同时也就确定了TB中码块(coding block，CB)的数目和大小，从而解出对应的TB。
这种方式的好处就是在不同的频段采用不同的MCS，获得频选调度增益。在调度的信令DCI中，会指示多个MCS，其中1个设置为参考MCS，其余的MCS表示为相对于reference MCS的相对值。这样可以起到降低调度开销的好处。
该方法中的差分MCS采用节省开销的方案应用在相同的时域符号中，可以用在不同的子带上，或者不同的码块上，或者不同的码块组上，其中一个子带对应分配带宽的一部分，该部分对应一个CB或者多个CB(CB group，码块组)，类似的，该方法还可以用到不同的时间单元中，终端可以通过接收一个参考MCS和一个相对值，就可以得到对应的MCS。
其中，另一种slot的发送方法可以包括：网络设备向终端发送一个TB的数据时，经过码块分割、信道编码、速率匹配、码块级联之后，使用现有技术直接进行调制。本方法与现有技术不同之处在于，进行码块的交织，交织完之后，采用相同的MCS进行调制，然后再进行RE的映射。
所述交织方式中，如果mini-slot包含有多个时域符号，而且所传输的内容对时延没有要求，则可以采用跨时域符号的交织方式对码块进行交织；如果所传输的内容对时延没有要求，则可以采用每个符号内部的交织方式对码块进行交织。最后进行资源的映射。
对应的，终端在接收数据的时候，根据调度信令中的DCI中的MCS对接收到的符号进行解调，解调出来后根据所采用的交织方式，进行解交织操作，从而解除对应的TB。
这种方式的好处就是进行了码块的交织，来对抗频率选择性衰落，同时交织的方式也考虑了不同的时延需求。
其中，另一种slot的发送方法可以包括：网络设备向终端发送一个TB的数据时，经过码块分割、信道编码、速率匹配、码块级联，且采用相同的MCS进行调制，调制完之后，使用现有技术直接进行资源的映射。本方法与现有技术的不同之处在于，进行调制符号的交织，然后再进行资源的映射。
所述交织方式中，如果mini-slot包含有多个时域符号，而且所传输的内容对时延没有要求，则可以采用跨时域符号的交织方式对调制符号进行交织；如果所传输的内容对时延没有要求，则可以采用每个时域符号内部的交织方式对调制符号进行交织。交织完之后进行资源的映射。
这种方式的好处就是进行了调制符号的交织，来对抗频率选择性衰落，同时交织的方式也考虑了不同的时延需求。
所述三种方案也可以应用到发送多个TB的情况，例如，不同的TB对应不同的子带。
其中，另一种slot的发送方法可以包括：网络设备向终端发送关于Subband(子带)的配置信息，其中一个子带对应分配带宽的一部分，该部分对应一个CB或者多个CB(CB group，码块组)。配置信息可以包括带宽，以及子带的个数，或者子带的频域大小以及子带的个数，或者带宽，以及子带的频域大小，或者带宽、子带的频域大小以及子带的个数。UE可以通过该配置信息获取对应的子带划分情况，从而确定自己对应的fftsize。作为一种UE能力，UE可以上报自己能支持的小区(载波)个数，或者子带的个数，或者小区个数及子带个数。
如果1个子带中包含1个码块组，则1个码块组内部可以进行码块的交织，该交织可以是对编码出来的比特进行的，或者可以是对调制之后的调制符号进行的。
