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清楚、完整地描述。
应理解，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)通信系统或未来的5G系统等。
特别地，本申请实施例的技术方案可以应用于各种基于非正交多址接入技术的通信系统，例如稀疏码多址接入(Sparse Code Multiple Access，SCMA)系统、低密度签名(Low Density Signature，LDS)系统等，当然SCMA系统和LDS系统在通信领域也可以被称为其他名称；进一步地，本申请实施例的技术方案可以应用于采用非正交多址接入技术的多载波传输系统，例如采用非正交多址接入技术正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)、滤波器组多载波(Filter Bank Multi-Carrier，FBMC)、通用频分复用(Generalized Frequency Division Multiplexing，GFDM)、滤波正交频分复用(Filtered-OFDM，F-OFDM)系统等。
本申请实施例中的终端设备可以指用户设备(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。接入终端可以是蜂窝电话、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处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional NodeB，eNB或eNodeB)，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，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
图1是本申请实施例一个应用场景的示意图。图1中的通信系统可以包括终端设备10和网络设备20。网络设备20用于为终端设备10提供通信服务并接入核心网，终端设备10通过搜索网络设备20发送的同步信号、广播信号等而接入网络，从而进行与网络的通信。图1中所示出的箭头可以表示通过终端设备10与网络设备20之间的蜂窝链路进行的上/下行传输。
在LTE系统中，物理下行控制信道PDCCH的时域位置是完全固定的，位于每个1ms子帧的开头几个符号(最多3个)。LTE FDD的同步信号SS位于一个子帧的前一个时隙的尾部，物理广播信道PBCH位于该子帧的后一个时隙的头部。LTE TDD的主同步信号(Primary Synchronization Signal，PSS)和辅同步信号(Secondary Synchronization Signal，SSS)位于不同时隙、不同子帧，分别位于时隙尾部和时隙的第三个符号，物理广播信道PBCH也是位于时隙的头部。
而在5G系统中，需要支持在高频段(中心频率在6GHz以上，典型的比如28GHz)进行数据传输，以达到5G对传输速率的要求。在高频段进行 数据传输时，为了达到更高的传输速率，需要采用多天线(Multiple Input Multiple Output，MIMO)技术。在高频采用MIMO技术对天线的射频器件要求很高，天线的硬件成本(比如模/数(Analog/Digital，A/D)，数/模D/A转换器)也会大大增加。为了降低成本，在高频段通常采用混合波束赋形的方式来减少收发射频单元的数量。由于采用了大量天线的天线阵，可以产生更窄的、方向性更好的波束，每个时间单元内只在某些波束上发送信号，能够集中能量，扩大覆盖。
为了便于理解，先简单描述一下终端设备与网络设备之间的基本通信流程。具体地，终端设备在开机后在可能小区的几个中心频点上接收主同步信号PSS和辅同步信号SSS以获得帧同步，之后就可以读取PBCH。从PBCH中可以获得系统带宽、物理混合自动重传指示信道(Physical Hybrid ARQ Indicator Channel，PHICH)资源、天线数或系统帧号等系统信息。终端设备还可以从系统消息中携带一些其他信息，驻留并使用该网络设备提供的各种服务。若网络设备有要向某个终端设备发送的下行数据时，网络设备首先会向终端设备发送一个下行控制信道，主要作用是告知终端设备为该下行数据分配的物理下行数据信道(Physical Downlink Shared Channel，PDSCH)安排在了资源格的什么位置，然后网络设备在为终端设备分配的位置向终端设备发送PDSCH。
图2示出了本申请实施例的传输信息的方法100的示意性框图。如图2所示，该方法100包括：
S110，终端设备在第一时隙或第一微时隙中接收网络设备发送的第一同步信号块和第一物理下行控制信道，该第一时隙或第一微时隙包括N个符号，该第一同步信号块占用该第一时隙或该第一微时隙中连续的M个符号，该第一同步信号块包括同步信号和物理广播信道，M、N均为正整数，且M≤N。
需要说明的是，其一，第一时隙或第一微时隙是时域调度单元，这里还可以是子帧或者其他长度的单位，一个时域调度单元可以是在时域上包括多个符号，在频域上包括多个子载波或者是整个系统带宽。其二，在NR系统中，每个波束的SS和PBCH在一个SS block中传输，多个波束的SS block合并为一个SS burst。换句话说，不同的同步信号块采用不同的波束。
具体地，在包括同步信号块的时域调度单元中可以同时配置一部分资源 用来传输物理下行控制信道。正如上所述，在LTE系统中，物理下行控制信道在一个子帧的前几个符号中，而同步信号和PBCH分别在不同时隙中，并且频域位于系统带宽中央的72个子载波。而在NR系统中，时域调度单元不再是一个子帧，可以是一个时隙或者微时隙等，并且系统的带宽会变大，若仍旧采用LTE系统中的时域调度单元的配置方式，那么包括同步信号的时域调度单元中频域上的其他位置就浪费了，而如果在传输同步信号块的时域调度单元中配置一部分资源来传输下行控制信道，可以在满足NR高频段的覆盖要求的同时可以提高资源利用率，缩短每个波束的传输时间，降低传输时延，容纳更多波束数量，从而提高通信系统的容量和覆盖。
可选地，在本申请实施例中，该方法100还可以包括：
S120、终端设备根据第一同步信号块进行区分是哪个网络设备或者实现与网络设备之间的同步等；终端设备还可以根据第一物理下行控制信道调度与该第一物理下行控制信道对应的物理下行数据信道。
可选地，若该第一时隙或第一微时隙中还有别的资源未配置，那么其他资源可以用来传输物理下行数据信道。这样可以扩展该波束下的数据信道的传输资源，也就是说，如果数据量不大时，可以不用为终端设备在该波束下分配新的时隙或微时隙。同时，也可以缩短一个波束的传输时间，在单位时间内容纳更多波束数量，从而提高通信系统的容量和覆盖。
可选地，在本申请实施例中，该第一物理下行控制信道所占的符号与该第一同步信号块所占的符号至少部分重叠，该第一物理下行控制信道所占的频域资源与该第一同步信号块所占的频域资源不重叠。
进一步地，该第一同步信号块占用该第一时隙或该第一微时隙的第1至第M个符号，该第一物理下行控制信道占用该第一时隙或该第一微时隙的第1至第P个符号，该第一物理下行控制信道在频域上位于该第一同步信号块带宽的至少一侧，P为正整数，且P≤M。
可选地，该第一同步信号块和该第一物理下行控制信道在时域上可以是部分重叠，也可以是完全重叠。例如，第一同步信号块占前M个符号，第一物理下行控制信道在第一同步信号块带宽的一侧，并且也占第一时隙或第一微时隙的前M个符号，也可以是占用前P个符号，且P≥M。
将第一同步信号块配置在第一时隙或第一微时隙的头几个符号来传输，能够使终端在完成小区搜索后马上读取当前时隙的下行控制信道和系统信 息，可以缩短终端接入网络的时间，节省终端入网过程中的耗电。
可选地，该第一物理下行控制信道可以配置在第一时隙和第二微时隙的中间连续的几个符号或后面几个连续的符号上，只要与第一同步信号块在时域上有重叠，在频域上不重叠即可。
可选地，在本申请实施例中，该第一物理下行控制信道所占的符号与该第一同步信号块所占的符号不重叠。
进一步地，该第一同步信号块占用该第一时隙或该第一微时隙的第N-M+1至第N个符号，该第一物理下行控制信道占用该第一时隙或该第一微时隙的第1至第P个符号，P为正整数，且P≤(N-M)。
可选地，第一同步信号块与第一物理下行控制信道在频域上可以重叠，也可以不重叠。在本申请实施例中，只要第一同步信号块和第一物理下行控制信道在时域上不重叠即可，具体地，可以将第一同步信号块配置在第一时隙或第一微时隙系统带宽的中央，并且占用第一时隙或第一微时隙的后几个符号。同样地，可以将第一物理下行控制信道配置在第一时隙或第一微时隙系统带宽的中央，并且占用第一时隙或第一微时隙的前几个符号。
可选地，在本申请实施例中，该方法还包括：该终端设备在第二时隙或第二微时隙中接收该网络设备发送的第二物理下行控制信道，该第二时隙或该第二微时隙不包括同步信号块，该第二物理下行控制信道在该第二时隙或该第二微时隙中的位置与该第一物理下行控制信道在该第一时隙或该第一微时隙中的位置相同。
对于终端设备来讲，一个终端可以对应一个波束，若网络设备要向终端设备发送的下行数据量较大时，可以在包括有同步信号块的时隙或微时隙中传输物理下行数据信道，也可以在不包括同步信号块的时隙或微时隙中传输物理下行数据信道。应理解，该不包括同步信号块的时隙或微时隙，即上述的第二时隙或第二微时隙也可以不包括物理下行控制信道，所有资源都用于传输物理下行数据信道。将第一时隙或第一微时隙和第二时隙或第二微时隙中的物理下行控制信道的位置配置成相同的，保持了控制信道的简单结构，能够避免配置控制信道位置的额外信令，降低信令开销，简化终端和网络设备的复杂度。
具体地，可以将第一物理下行控制信道和第二物理下行控制信道分别配置在第一时隙或第一微时隙和第二时隙或第二微时隙的前几个符号，例如， 前3个符号等。
可选地，在本申请实施例中，该方法还包括：该终端设备在第二时隙或第二微时隙中接收网络设备发送的第二物理下行控制信道，该第二时隙或该第二微时隙不包括同步信号块，该第二物理下行控制信道在该第二时隙或该第二微时隙中的位置与该第一物理下行控制信道在该第一时隙或该第一微时隙中的位置不同。
应理解，网络设备通常会通过PBCH或者系统消息向终端设备发送指示下行控制信道公共搜索空间的资源信息。
进一步地，若第一时隙或第一微时隙和第二时隙或第二微时隙中的物理下行控制信道的位置不同，那么网络设备会向终端设备发送第一指示信息和第二指示信息，分别指示第一物理下行控制信道在该第一时隙或该第一微时隙中的位置，该第二指示信息用于指示该第二物理下行控制信道在该第二时隙或该第二微时隙中的位置；该终端设备根据该第一指示信息和第二指示信息，分别确定该第一物理下行控制信道在该第一时隙或该第一微时隙中的位置和第二物理下行控制信道在该第二时隙或该第二微时隙中的位置。
该第一指示信息和第二指示信息可以承载在一条消息中，也可以分开发送。
可选地，在本申请实施例中，该第一物理下行控制信道用于调度以下物理下行数据信道中的至少一种物理下行数据信道：该第一时隙或该第一微时隙中的物理下行数据信道、该第一时隙或第一微时隙之后的至少一个时隙或微时隙中的物理下行数据信道和该第一时隙或第一微时隙之前的至少一个时隙或微时隙中的物理下行数据信道。
也就是说，时隙或微时隙中的物理下行控制信道既可以调度本时隙或本微时隙中的物理下行数据信道，也可以调度别的时隙或微时隙中的物理下行数据信道。别的时隙或微时隙可以是本时隙或本微时隙之前的一个或多个时隙或微时隙中的物理下行数据信道，也可以是本时隙或本微时隙之后的一个或多个时隙或微时隙中的物理下行数据信道。
具体地，若该第一物理下行控制信道调度第一时隙或第一微时隙之前的时隙或微时隙中的物理下行数据信道，可以通过以下方式获取数据：
该终端设备接收第三指示信息，该第三指示信息用于指示能够被该第一物理下行控制信道调度的物理下行数据信道在该至少一个时隙或微时隙中 的位置；该终端设备根据该指示信息，缓存该至少一个时隙或微时隙中能够被该第一物理下行控制信道调度的物理下行数据信道上承载的数据；该终端设备根据该第一物理下行控制信道，在该终端设备缓存的该至少一个时隙或微时隙中能够被该第一物理下行控制信道调度的物理下行数据信道上承载的数据中获取与该第一物理下行控制信道对应的数据。
可选地，该第三指示信息可以承载于无线资源控制RRC信令中，也就是说，能够被该第一物理下行控制信道调度的物理下行数据信道在该至少一个时隙或微时隙中的位置可以通过静态配置的方式，网络设备也可以不用发送第三指示信息，直接采用协议约定的方式。例如，协议约定好能够被第一时隙或第一微时隙中的物理下行控制信道调度的前一个时隙或微时隙中的物理下行数据信道包括该时隙或微时隙的后两个符号，那么终端设备可以首先缓存该两个符号上的数据，当终端设备接收到第一物理下行数据信道时，即可知道第一物理下行控制信道调度的物理下行数据信道位于第一时隙或第一微时隙之前的时隙或微时隙中，可以从缓存的数据中获取与该第一物理下行控制信道对应的数据。
可选地，在本申请实施例中，该方法还包括：该终端设备在第三时隙或第三微时隙接收该网络设备发送的第二同步信号块和第三物理下行控制信道，该第二同步信号块包括同步信号和物理广播信道，该第一同步信号块和该第二同步信号块不同。
可选地，在本申请实施例中，该第一时隙或该第一微时隙和该第三时隙或该第三微时隙被该网络设备连续调度。
具体地，终端设备可以优先连续接收好几个包括同步信号块的时隙或微时隙，然后再连续接收与同步信号块对应的不包括同步信号块的时隙或微时隙。其中，不同的同步信号块对应不同的波束。换句话说，所有包括同步信号块的时隙或微时隙连续传输。终端设备可以连续接收同步信号块，节省终端耗电。
可选地，对应同一波束的包括同步信号块的时隙或微时隙与不包括同步信号块的时隙或微时隙连续传输，所有包括同步信号块的时隙或微时隙可以不连续传输。
下面将结合图3至图12，详细描述本发明实施例的三种具体的时域调度单元的结构。
第一种结构，同步信号块占用时域调度单元的全部符号。
实施例一：如图3所示，同步信号块在一个和同步信号块等长的微时隙中传输，PDCCH、PDSCH在同步信号块所在符号传输，占用同步信号块带宽两侧的频域资源。其中PDCCH可以位于同步信号块一侧，也可以位于两侧。此实施例中，先连续传输各波束的包含同步信号块的微时隙，再传输各波束的不包含同步信号块的微时隙或时隙。同一波束可以既有包括同步信号块的时域调度单元，又有不包括同步信号块的时域调度单元。
应理解，实施例一是以图3中同步信号块占用系统带宽的中央，不包括同步信号块的时域调度单元是以PDCCH占用该时域调度单元前几个符号为例进行说明，每个时域调度单元中的PDCCH还可以占用该时域调度单元中的中间连续的符号或后几个连续的符号。不包括同步信号块的时域调度单元可以只用来传输数据，由同一波束的包括同步信号块的时域调度单元中的物理下行控制信道调度。
该实施例一的优点是可以使终端在完成小区搜索后马上读取当前时隙的下行控制信道和系统信息，且同步信号块连续传输，可以缩短终端设备搜索同步信号和读取PBCH的时间，节省终端耗电，且不包括同步信号块的时频资源可以灵活分配。
实施例二：如图4所示，同步信号块在一个和同步信号块等长的微时隙中传输，PDCCH、PDSCH在同步信号块所在符号传输，占用同步信号块带宽两侧的频域资源。其中PDCCH可以位于同步信号块一侧，也可以位于两侧。与实施例一的区别在于，各个波束的包括同步信号块的微时隙不连续传输，某个波束包括同步信号块的微时隙与不包括同步信号块的微时隙连续传输。
应理解，实施例二是以图4中同步信号块占用系统带宽的中央，不包括同步信号块的时域调度单元是以PDCCH占用该时域调度单元前几个符号为例进行说明，每个时域调度单元中的PDCCH还可以占用该时域调度单元中的中间连续的符号或后几个连续的符号。不包括同步信号块的时域调度单元可以只用来传输数据，由同一波束的包括同步信号块的时域调度单元中的物理下行控制信道调度。
该实施例二的优点是终端在完成小区搜索后马上读取当前时隙的下行控制信道和系统信息，终端入网速度较快，且波束间切换次数较少，可以降 低终端设备和网络设备的操作复杂度。
第二种结构，同步信号块占用时域调度单元的头部。
实施例三：如图5所示，同步信号块在一个长于同步信号块的时隙或微时隙的头部传输，PDCCH在同步信号块所在符号传输，占用同步信号块带宽两侧的频域资源。其中PDCCH可以位于同步信号块一侧，也可以位于两侧。此实施例中，先连续传输各波束的包含同步信号块的时隙或微时隙，再传输各波束的不包含同步信号块的时隙或微时隙。同一波束可以既有包括同步信号块的时域调度单元，又有不包括同步信号块的时域调度单元。
应理解，实施例三是以图5中同步信号块占用系统带宽的中央，不包括同步信号块的时域调度单元是以PDCCH占用该时域调度单元前几个符号为例进行说明，每个时域调度单元中的PDCCH还可以占用该时域调度单元中的中间连续的符号或后几个连续的符号。只要在包括同步信号块的时域调度单元中同步信号块与PDCCH在时域上重叠即可。不包括同步信号块的时域调度单元可以只用来传输数据，由同一波束的包括同步信号块的时域调度单元中的物理下行控制信道调度。
该实施例三的优点是可以使终端在完成小区搜索后马上读取当前时隙的下行控制信道和系统信息，可以缩短终端接入网络的时间，节省终端入网过程中的耗电，且包括同步信号块的时隙或微时隙具有更多的传输数据的资源，在很多情况下可以不采用不包括同步信号块的时隙或微时隙就可以实现较灵活的资源分配。
实施例四：如图6所示，同步信号块在一个长于同步信号块的时隙或微时隙的头部传输，PDCCH在同步信号块所在符号传输，占用同步信号块带宽两侧的频域资源。其中PDCCH可以位于同步信号块一侧，也可以位于两侧。实施例四与实施例三的区别在于，各个波束的包括同步信号块的时隙或微时隙连续传输，某个波束包括同步信号块的时隙或微时隙与不包括同步信号块的时隙或微时隙不连续传输。
应理解，实施例四是以图6中同步信号块占用系统带宽的中央，不包括同步信号块的时域调度单元是以PDCCH占用该时域调度单元前几个符号为例进行说明，每个时域调度单元中的PDCCH还可以占用该时域调度单元中的中间连续的符号或后几个连续的符号。只要在包括同步信号块的时域调度单元中同步信号块与PDCCH在时域上重叠即可。不包括同步信号块的时域 调度单元可以只用来传输数据，由同一波束的包括同步信号块的时域调度单元中的物理下行控制信道调度。
该实施例四的优点是终端在完成小区搜索后马上读取当前时隙的下行控制信道和系统信息，终端入网速度较快，包括同步信号块的时隙或微时隙具有更多的传输数据的资源，在很多情况下可以不采用不包括同步信号块的时隙或微时隙就可以实现较灵活的资源分配，且波束间切换次数较少，可以降低终端设备和网络设备的操作复杂度。
实施例五：如图7所示，同步信号块在一个长于同步信号块的时隙或微时隙的头部传输，PDCCH在同步信号块所在符号传输，占用同步信号块带宽两侧的频域资源。其中PDCCH可以位于同步信号块一侧，也可以位于两侧。不包括同步信号块的时隙或微时隙中的PDCCH占用所在时域调度单元中的头几个符号。包括同步信号块的时隙或微时隙中的PDCCH和不包括同步信号块的时隙或微时隙中的PDCCH可以调度本时隙或微时隙中的PDSCH，也可以调度本时隙或本微时隙之后的PDSCH，还可以调度本时隙或本微时隙之前的PDSCH。各个波束的包括同步信号块的时隙或微时隙连续传输，某个波束包括同步信号块的时隙或微时隙与不包括同步信号块的时隙或微时隙不连续传输。
PDCCH可以调度本时域调度单元之前的其他时域调度单元中的PDSCH，该其他时域调度单元可以是包括同步信号块的时域调度单元，也可以是不包括同步信号块的时域调度单元。可以通过以下方式实现：
网络设备发送第一指示信息，通知终端设备可能存在被调度的PDSCH位于该PDCCH之前的时域调度单元之内的情况。所述第一指示信息采用半静态消息，如RRC信令传输。该第一指示信息用于指示被调度的PDSCH在该PDCCH之前的时域调度单元内的位置信息。网络设备发送通过该PDCCH发送第二指示信息，指示被调度的PDSCH位于该PDCCH之前的时域调度单元之内。
应理解，网络设备也可以不用向终端设备发送第一指示信息，直接采用协议规定的方式，也就是说网络设备在调度该PDCCH之前的时域调度单元时，终端设备直接将协议规定的该时域调度单元中的PDSCH上承载的数据换粗，当终端设备接收到网络设备发送的该PDCCH，终端设备即可知道在缓存的数据中获取与该PDCCH对应的数据。
该实施例五进一步提高了资源调度的灵活性。PDCCH不仅可以调度本时隙或微时隙和其后时隙或微时隙的资源，还可以调度之前一个时隙或微时隙的部分资源。这样可以扩展该波束的PDSCH传输资源，又不需要为该波束分配新的时隙或微时隙。
实施例六：如图8所示，同步信号块在一个长于同步信号块的时隙或微时隙的头部传输，PDCCH在同步信号块所在符号传输，占用同步信号块带宽两侧的频域资源。其中PDCCH可以位于同步信号块一侧，也可以位于两侧。不包括同步信号块的时隙或微时隙中的PDCCH占用所在时域调度单元中的头几个符号。包括同步信号块的时隙或微时隙中的PDCCH和不包括同步信号块的时隙或微时隙中的PDCCH可以调度本时隙或微时隙中的PDSCH，也可以调度本时隙或本微时隙之后的PDSCH，还可以调度本时隙或本微时隙之前的PDSCH。各个波束的包括同步信号块的时隙或微时隙不连续传输，某个波束包括同步信号块的时隙或微时隙与不包括同步信号块的时隙或微时隙连续传输。
同样地，该实施例六进一步提高了资源调度的灵活性。PDCCH不仅可以调度本时隙或微时隙和其后时隙或微时隙的资源，还可以调度之前一个时隙或微时隙的部分资源。这样可以扩展该波束的PDSCH传输资源，又不需要为该波束分配新的时隙或微时隙。
第三种结构，同步信号块位于所在时域调度单元的尾部。
实施例七：如图9所示，同步信号块在一个长于同步信号块的时隙或微时隙的尾部传输，PDCCH在该时隙或微时隙的头部传输，同步信号块和PDCCH占用不同的符号。此实施例中，先连续传输各波束的包含同步信号块的时隙或微时隙，再传输各波束的不包含同步信号块的时隙或微时隙。
应理解，包括同步信号块的时域调度单元和不包括同步信号块的时域调度单元中的PDCCH的位置可以相同，也可以不同，本实施例以相同为例进行描述。并且上述实施例的一些扩展同样适用于本实施例，为了简洁，在此不再赘述。
该实施例七的优点是PDCCH和同步信号块在不同符号传输，PDCCH的频域资源不受同步信号影响，包含同步信号块的时隙或微时隙和不包含同步信号块的时隙或微时隙中，PDCCH可以采用相同的结构，从而简化了网络设备和终端设备的复杂度，节省了信令开销。
实施例八：如图10所示，同步信号块在一个长于同步信号块的时隙或微时隙的尾部传输，PDCCH在该时隙或微时隙的头部传输，同步信号块和PDCCH占用不同的符号。与实施例七的区别在于，各个波束的包含同步信号块的时隙或微时隙不连续传输，某个波束包含同步信号块的时隙或微时隙与不包含同步信号块的时隙或微时隙连续传输。
该实施例八的优点是波束间切换次数较少，且包含同步信号块的时隙或微时隙和不包含同步信号块的时隙或微时隙中，PDCCH可以采用相同的结构，从而简化了网络设备和终端设备的复杂度，节省了信令开销。
实施例九：如图11所示，同步信号块在一个长于同步信号块的时隙或微时隙的尾部传输，PDCCH在该时隙或微时隙的头部传输，同步信号块和PDCCH占用不同的符号。此实施例中，先连续传输各波束的包含同步信号块的时隙或微时隙，再传输各波束的不包含同步信号块的时隙或微时隙。不包括同步信号块的时隙或微时隙中的PDCCH可以调度本时隙或微时隙中的PDSCH，也可以调度本时隙或本微时隙之后的PDSCH，还可以调度本时隙或本微时隙之前的PDSCH。
该实施例相对于实施例七，进一步提高了资源调度的灵活性，PDCCH不仅可以调度本时隙或微时隙和其后时隙或微时隙的资源，还可以调度之前一个时隙或微时隙的部分资源。这样可以扩展该波束的PDSCH传输资源，又不需要为该波束分配新的时隙或微时隙。
实施例十：如图12所示，同步信号块在一个长于同步信号块的时隙或微时隙的尾部传输，PDCCH在该时隙或微时隙的头部传输，同步信号块和PDCCH占用不同的符号。与实施例九的区别在于，各个波束的包含同步信号块的时隙或微时隙不连续传输，某个波束包含同步信号块的时隙或微时隙与不包含同步信号块的时隙或微时隙连续传输。包括同步信号块的时隙或微时隙中的PDCCH可以调度本时隙或微时隙中的PDSCH，也可以调度本时隙或本微时隙之后的PDSCH，还可以调度本时隙或本微时隙之前的PDSCH。
该实施例相对于实施例八，进一步提高了资源调度的灵活性，PDCCH不仅可以调度本时隙或微时隙和其后时隙或微时隙的资源，还可以调度之前一个时隙或微时隙的部分资源。这样可以扩展该波束的PDSCH传输资源，又不需要为该波束分配新的时隙或微时隙。
