相关申请的交叉引用
本申请主张在2018年9月20日在中国提交的中国专利申请号No.201811103528.6的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种传输指示信号的传输方法、网络设备及终端。
背景技术
在新空口(New Radio，NR)的非授权频段上，在发送信息之前，终端或网络设备需要做信道空闲估计(Clear Channel Assess，CCA)/扩展信道空闲估计(extended Clear Channel Assess，eCCA)来侦听信道，即进行能量检测(Energy Detection，ED)，当能量低于一定门限时，信道被判断为空，方可开始传输。由于非授权频段是多种技术或多个传输节点共享，因此这种基于竞争的接入方式导致信道可用时间的不确定性，当信道可用(available)时，网络侧信号传输的可传输位置可能已经错过而无法发送，这样可能导致接收端无法正常接收网络侧配置的信号接收，以及信号接收后根据网络侧的配置进行的终端行为，例如物理下行控制信道(Physical Downlink Control Channel，PDCCH)监听，对无线环境的监测和测量等。
发明内容
本公开实施例提供了一种传输指示信号的传输方法、网络设备及终端，以解决非授权频段上因终端无法接收到参考信号(Reference Signal,RS)而导致的下行信号无法正常接收的问题。
第一方面，本公开实施例提供了一种传输指示信号的传输方法，应用于终端侧，包括：
在网络设备占用的时频资源中的部分资源上接收传输指示信号，其中， 传输指示信号用于指示终端根据终端行为指示信息执行相应的终端行为，终端行为指示信息用于指示终端行为。

第三方面，本公开实施例提供了一种终端，终端包括处理器、存储器以及存储于存储器上并在处理器上运行的计算机程序，计算机程序被处理器执行时实现上述的传输指示信号的传输方法的步骤。
第四方面，本公开实施例提供了一种传输指示信号的传输方法，应用于网络设备侧，包括：
在占用的时频资源中的部分资源上发送传输指示信号，其中，传输指示信号用于指示终端根据终端行为指示信息执行相应的终端行为，终端行为指示信息用于指示终端行为。

第一发送模块，用于在占用的时频资源中的部分资源上发送传输指示信号，其中，传输指示信号用于指示终端根据终端行为指示信息执行相应的终端行为，终端行为指示信息用于指示终端行为。
第六方面，本公开实施例还提供了一种网络设备，网络设备包括处理器、存储器以及存储于存储器上并在处理器上运行的计算机程序，处理器执行计算机程序时实现上述的传输指示信号的传输方法的步骤。
第七方面，本公开实施例提供了一种计算机可读存储介质，计算机可读存储介质上存储有计算机程序，计算机程序被处理器执行时实现上述的传输指示信号的传输方法的步骤。
这样，本公开实施例的终端可以在接收到传输指示信号后，再根据终端行为指示信息执行相应的终端行为，以避免不必要的行为尝试，可以提高传输性能，并节省终端耗电。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤 或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。说明书以及权利要求中“和/或”表示所连接对象的至少其中之一。
本文所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。术语“系统”和“网络”常被可互换地使用。本文所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了NR系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用。
以下描述提供示例而并非限定权利要求中阐述的范围、适用性或者配置。可以对所讨论的要素的功能和布置作出改变而不会脱离本公开的精神和范围。各种示例可恰适地省略、替代、或添加各种规程或组件。例如，可以按不同于所描述的次序来执行所描述的方法，并且可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
请参见图1，图1示出本公开实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本公开实施例中并不限定终端11的具体类型。网络设备12可以是基站或核心网，其中，上述基站可以是第五代移动通信技术(fifth generation cellular network technology，5G)及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、无线局域网(Wireless Local Area  Network，WLAN)接入点、或其他接入点等)，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、无线保真(Wireless Fidelity，WiFi)节点或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本公开实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
基站可在基站控制器的控制下与终端11通信，在各种示例中，基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中，这些基站中的一些可以通过回程链路直接或间接地彼此通信，回程链路可以是有线或无线通信链路。无线通信系统可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如，每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如，参考信号、控制信道等)、开销信息、数据等。
基站可经由一个或多个接入点天线与终端11进行无线通信。每个基站可以为各自相应的覆盖区域提供通信覆盖。接入点的覆盖区域可被划分成仅构成该覆盖区域的一部分的扇区。无线通信系统可包括不同类型的基站(例如宏基站、微基站、或微微基站)。基站也可利用不同的无线电技术，诸如蜂窝或WLAN无线电接入技术。基站可以与相同或不同的接入网或运营商部署相关联。不同基站的覆盖区域(包括相同或不同类型的基站的覆盖区域、利用相同或不同无线电技术的覆盖区域、或属于相同或不同接入网的覆盖区域)可以交叠。
无线通信系统中的通信链路可包括用于承载上行链路(Uplink，UL)传输(例如，从终端11到网络设备12)的上行链路，或用于承载下行链路(Downlink，DL)传输(例如，从网络设备12到终端11)的下行链路。UL传输还可被称为反向链路传输，而DL传输还可被称为前向链路传输。下行链路传输可以使用授权频段、非授权频段或这两者来进行。类似地，上行链 路传输可以使用有授权频段、非授权频段或这两者来进行。
本公开实施例提供了一种传输指示信号的传输方法，应用于终端侧，如图2所示，该方法包括以下步骤：
步骤21：在网络设备占用的时频资源中的部分资源上接收传输指示信号，其中，传输指示信号用于指示终端根据终端行为指示信息执行相应的终端行为。
其中，终端行为指示信息用于指示终端行为。以NR系统为例，在NR的非授权频段上，网络设备在发送下行信息之前，需要对信道进行监听，当监听到空闲信道并成功占用后才可以发送下行信息。其中，传输指示信号用于指示网络设备成功占用了空闲信道，也就是说，当网络设备成功占用空闲信道后，向终端发送传输指示信号，为了使得终端能够尽快的检测到传输指示信号，网络设备可在占用的时频资源中多次发送传输指示信号，以保证终端能够接收到该传输指示信号。这样，终端在接收到该传输指示信号后，可依据先前接收到的终端行为指示信息来执行相应的终端行为。
其中，终端行为指示信息用于指示终端需要执行相应的终端行为，终端行为指示信息是网络设备预先配置给终端的，具体可通过但不限于通过高层信令，如无线资源控制(Radio Resource Control，RRC)信令，或者媒体接入控制(Medium Access Control，MAC)控制单元(Control Element，CE)等。
本公开实施例的传输指示信号可以通过物理信号或物理信道的形式进行传输。例如，传输指示信号通过以下形式中的一种进行传输：
PDCCH；
PDCCH的解调参考信号(De-Modulation Reference Signal，DMRS)；
物理下行共享信道(Physical Downlink Share Channel，PDSCH)的DMRS；
信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)；以及，
预设序列。其中，预设序列包括：ZC序列、Gold序列、m序列中的至少一项，即预设序列可以是ZC序列、Gold序列或m序列，也可以是ZC序列、Gold序列和m序列中多个序列的集合。或者，预设序列包括：由ZC序列、Gold序列、m序列中的至少两项调制形成的调制序列，即预设序列可以 是ZC序列、Gold序列和m序列中至少两个序列的调制。
也就是说，当传输指示信号以物理信道形式进行传输时，可以通过PDCCH传输。当传输指示信号以物理信号形式进行传输时，可以通过PDCCH的DMRS、PDSCH的DMRS、CSI-RS和预设序列中的至少一项进行传输。
本公开实施例的方法中，在步骤21之前还包括：接收传输指示信号的配置信息。也就是说，网络设备可以对传输指示信号进行配置，其中，配置信息包括但不限于：传输指示信号的传输周期、所在的时隙(slot)、所在slot中的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号位置、所在slot中的OFDM符号数量、所在OFDM符号上的资源块(Resource Block，RB)和准共址(Quasi Co-Location，QCL)关系中的至少一项。其中，QCL关系包括：传输指示信号与以下中的至少一项准共址：同步信号块(Synchronization Signal and PBCH Block，SSB)、发现信号(discovery signal)和CSI-RS。也就是说，传输指示信号可以与SSB准共址，或传输指示信号可以与发现信号准共址，或传输指示信号可以与CSI-RS准共址。
下面本实施例，将结合不同传输形式的应用示例对传输指示信号做进一步说明。
示例一、传输指示信号以PDCCH的形式进行传输
当传输指示信号通过PDCCH传输时，传输指示信号的配置信息包括：PDCCH的监听周期、监听持续时间、slot偏移、slot中的OFDM符号、所在的控制资源集CORESET、下行控制信息(Downlink Control Information，DCI)格式(format)、DCI尺寸(size)、控制信道元素(Control Channel Element，CCE)的聚合等级(Aggregation level，AL)和监听的CCE候选(candidate)集合中的至少一项。
进一步地，对于该PDCCH可以定义一种无线网络临时标识(Radio Network Temporary Identity，RNTI)，使用一种特定的RNTI进行传输该传输指示信号的循环冗余校验(Cyclic Redundancy Check，CRC)加扰。终端在检测到作为传输指示信号的PDCCH的DCI后，基于其中的指示获取网络设备的占用的用于信号发送的信道的的起始时间(段)、持续时间和结束时间(段)。终端可以根据该结束时间(段)，确定在什么时间可以停止进行下行接收。
示例二、传输指示信号以PDCCH的DMRS的形式进行传输
网络设备占用到空闲信道后的信道占用时间(Channel Occupancy Time，COT)内，周期性的发送该PDCCH的DMRS，终端一旦检测到该PDCCH的DMRS，则认为网络设备获得了信道资源，可以进行传输，终端从而进行后续的接收。
该PDCCH的DMRS为带宽DMRS，即在控制资源集(Control Resource set，CORESET)内的每个RB上都存在PDCCH的DMRS。其中，PDCCH的DMRS所在的CORESET的时域位置可以是预定义的，例如在每个slot第0个和/或第7个OFDM符号为该CORESET的起始位置。
进一步地，带宽DMRS在控制资源集CORESET中连续的资源块RB的资源元素组(Resource Element Group，REG)上映射，且CORESET的预编码颗粒度(Precoder Granularity)与CORESET所包含的RB数相同。
该传输指示信号的配置信息包括：PDCCH的DMRS所在的CORESET和/或CORESET的时域位置。也就是说，PDCCH-DMRS的CORESET的时频资源位置除了可以是预定义的外，还可以是网络设备配置的，如通过高层信令进行配置。传输该PDCCH的DMRS的CORESET的时间资源可以是周期性的，也就是说网络设备可以以固定周期向终端发送传输指示信号。
例如，如图3所示，网络设备在占用到信道后的COT内以每7或者14个OFDM符号为周期，在每个slot第0个和/或第7个OFDM符号上传输该PDCCH的DMRS，该周期可以为预定义的或者由高层信令配置的。PDCCH的DMRS的CORESET可以为占用两个OFDM符号，带宽为48个RB的CORESET。
示例三、传输指示信号以PDSCH的DMRS或CSI-RS形式传输
网络设备占用到信道后的COT内，传输PDSCH的DMRS/CSI-RS，终端一旦检测到PDSCH的DMRS/CSI-RS，则认为网络设备获得了空闲信道资源，并可以进行传输，终端从而进行后续的接收。
其中，PDSCH的DMRS或CSI-RS的时域位置可以是预定义的，例如固定在每个slot的第3个和第10个OFDM符号上进行传输。或者，PDSCH的DMRS或CSI-RS的时域位置可以是网络设备配置的。传输该PDSCH的 DMRS或CSI-RS的时间资源可以是周期性的，也就是说网络设备可以以固定周期向终端发送传输指示信号。
例如，如图4所示，网络设备在占用到信道后的COT内以每7或者14个OFDM符号为周期，在每个slot的第3个和第10个OFDM符号上传输该PDSCH的DMRS或CSI-RS，该周期可以为预定义的或者由高层信令配置的。其中，网络设备发送该PDSCH的DMRS或CSI-RS可以预定义为全带宽发送、单端口发送或多端口发送。或者，网络设备还可通过高层信令配置该PDSCH的DMRS或CSI-RS发送占用的RB以及对应的端口数、加扰标识符(Identifier，ID)等。
具体地，当传输指示信号通过PDSCH的DMRS传输时，传输指示信号的配置信息包括：PDSCH的DMRS所在OFDM符号和/或OFDM符号上的RB。例如该PDSCH的DMRS在传输信道带宽上对应OFDM符号上的部分或全部RB上进行传输。
当传输指示信号通过CSI-RS传输时，传输指示信号的配置信息包括：CSI-RS的端口数、周期、所在的时域位置、所在的频域位置、密度、码分复用(Code Division Multiple，CDM)类型(type)、功率大小、时域位置上的RB、加扰ID和传输配置指示(Transmission Configuration Indicator，TCI)状态中的至少一项。例如，该CSI-RS在传输信道带宽上对应OFDM符号上的部分或全部RB上进行传输。此外，CSI-RS可以以跟踪参考信号(Tracking Reference Signal，TRS)的形式进行配置。
示例四、传输指示信号以预设序列形式传输
当传输指示信号通过预设序列传输时，传输指示信号的配置信息包括：预设序列的生成参数、周期、所在时域资源(如系统帧frame、子帧subframe、时隙slot、OFDM符号等)、功率大小和预设序列的传输资源中的至少一项。例如，传输一次该资源所占用的时频资源可以占用1个OFDM符号上的多个RB，或者一个slot上多个OFDM符号上的一个RB上进行传输。
其中，预设序列的生成参数与网络设备的信道占用时间COT的时间信息相关，时间信息包括：COT的起始时刻、持续时间和结束时刻中的至少一项。其中，COT的起始时刻亦可以称为COT的起始时间(段)，COT的结束时刻 又可以称为COT的结束时间(段)。终端可以根据预设序列的检测，获得网络设备当前传输的COT信息，如COT的起始时刻、持续时间和结束时刻等。
预设序列在网络设备的COT中进行周期性发送，例如如图5所示，在COT中以7或14个OFDM符号为周期进行发送。其中，传输周期、时域资源位置可以由高层信令配置。
预设序列还可以在信道带宽内的部分物理资源块(Physical Resource Block，PRB)上进行传输，即部分PRB为专门预留给该预设序列进行传输，该预设序列可以在这个RB带宽内，以时间方向重复发送，和/或，按照先频率后时间方向的序列映射。如图6所示，预设序列在一个RB上传输。此外，预设序列也可以在多个RB上发送，多个RB可以连续或者不连续。传输的RB(s)可以是预定义的或者由高层信令配置的。
1、假设传输指示信号以m序列形式传输，该传输指示信号的生成公式如下：
d seq(n)＝[1-2x 0((n+m 0)mod127)][1-2x 1((n+m 1)mod127)]
其中，m_0和m_1为循环移位值，0≤n＜M，M表示序列长度。循环移位值和序列长度可以为预定义的或者由高层信令配置的。该循环移位值可以和小区ID有关。进一步的，不同的m序列的循环移位值可以和COT的信息相关，该信息包括：COT的起始时间(段)、COT的持续时间、COT的结束时间(段)等。终端可以根据该COT的结束时间(段)，确定在什么时间可以停止进行下行接收。
例如，可以采用和辅同步信号(Secondary Synchronization Signal，SSS)相同的生成多项式，如下所示：
d seq(n)＝[1-2x 0((n+m 0)mod127)][1-2x 1((n+m 1)mod127)]
Figure PCTCN2019101972-appb-000001
Figure PCTCN2019101972-appb-000002
其中，0≤n＜M，M≥127，x 0(i+7)＝(x 0(i+4)+x 0(i))mod2，x 1(i+7)＝(x 1(i+1)+x 1(i))mod2，
且[x 0(6)x 0(5)x 0(4)x 0(3)x 0(2)x 0(1)x 0(0)]＝[0 0 0 0 0 0 1]
[x 1(6)x 1(5)x 1(4)x 1(3)x 1(2)x 1(1)x 1(0)]＝[0 0 0 0 0 0 1]
当M大于127时，前127个序列符号和SSS相同，这样终端可以使用已有的基于SSS的测量模块在127个资源元素(Resource Element，RE)上进行测量。当M＝127时，该序列和SSS序列完全相同，需要说明的是，虽然序列完全相同，由于SSS并不在一个传统的SSB的结构，即在相邻的资源上不存在主同步信号(Primary Synchronization Signal，PSS)、PBCH、PBCH-DMRS，所以该信号可以不认为是一个SSS。该m序列可以在时间和/或频率方向上离散或者连续的资源上进行发送。
2、假设传输指示信号以ZC序列形式传输，ZC序列的根索引、序列组号、序列号或者循环移位值为预定义或者由高层信令配置。其中，该循环移位值也可以和小区ID有关。进一步的，不同的ZC序列根索引、序列组号、序列号或者循环移位值可以和COT的信息相关，该信息包括至少如下之一：COT的起始时间(段)、COT的持续时间和/或COT的结束时间(段)等。终端可以根据该COT的结束时间(段)，确定在什么时间可以停止进行下行接收。该ZC序列可以在时间和/或频率方向上离散或者连续的资源上进行发送。
3、假设传输指示信号以Gold序列形式传输，该Gold序列的初始化方式至少和以下其中一项有关：COT的起始时间(段)、COT的持续时间、COT的结束时间(段)、cell ID、该序列所在的OFDM符号的编号等。终端可以根据该COT的结束时间(段)，确定在什么时间可以停止进行下行接收。例如：

其中，T COT为COT中的相关信息，例如指示该COT结束的slot，终端可以盲检该序列，并根据检测结果，确定该T COT的值，从而确定COT的结束slot，在该结束slot之后，终端可以不进行下行PDCCH或PDSCH等接收及基于下行RS的测量等。
4、假设传输指示信号以调制序列形式传输，例如该传输指示信号为至少两个序列的调制之后的调制序列；这两个序列可以为m序列、ZC序列和Gold序列中的至少两个。这里所说的调制指的是：在比特级为两个二进制序列的 模2加，即加扰；或者指的是：符号级的调制，如将两个序列至少其中之一映射为符号之后的符号级的相乘。例如两个m序列符号级的相乘，ZC序列和Gold序列的符号级相乘。例如，d1和d2为两个不同的比特序列或者符号序列：d(n)＝d 1(n)·d 2(n)，其中，0≤n≤N-1，N为序列的长度。
其中值得指出的是，当终端工作在非连续接收(Discontinuous Reception，DRX)场景下时，终端仅需要在DRX的激活期(active或On duration)的时间段内进行传输指示信号的检测。如图7所示，网络设备获得的空闲信道从第1个subframe开始，而终端的DRX active时间从第2个subframe开始，则终端只需要在DRX active期间进行该传输指示信号的检测。网络设备需要在占用的用于信号发送的信道内周期性的重复发送传输指示信号，以保证不同具有不同DRX active time的终端能够尽早检测到该传输指示信号。
进一步地，终端在接收到传输指示信号之后，即在步骤21之后，还包括：接收下行物理信号或下行物理信道；其中，下行物理信号或下行物理信道与传输指示信号的传输资源不重叠。假设网络设备调度的下行物理信号或下行物理信道资源和该传输指示信号占用的部分RE/RB资源相同，则下行物理信号或下行物理信道不在这些RE/RB上映射，终端认为下行物理信号或下行物理信道对这些RE/RB资源进行了速率匹配。其中，下行物理信道包括：物理下行广播信道(Physical Broadcast Channel，PBCH)、PDCCH和PDSCH中的至少一项。

无线资源管理(Radio Resource Management，RRM)测量，如参考信号接收功率(Reference Signal Received Power，RSRP)、参考信号接收质量 (Reference Signal Received Quality，RSRQ)和接收信号强度指示(Received Signal Strength Indicator，RSSI)等。
波束管理(Beam management)测量；
无线链路监测；以及，

对应于上述示例二，传输指示信号以PDCCH的DMRS的形式进行发送
网络设备占用到空闲信道后的信道占用时间COT内，周期性的发送该PDCCH的DMRS。

对应于示例三，传输指示信号以PDSCH的DMRS或CSI-RS形式发送
网络设备占用到信道后的COT内，传输PDSCH的DMRS/CSI-RS。其中，PDSCH的DMRS或CSI-RS的时域位置可以是预定义的，例如固定在每个slot的第3个和第10个OFDM符号上进行传输。或者，PDSCH的DMRS或CSI-RS的时域位置可以是网络设备配置的。传输该PDSCH的DMRS或CSI-RS的时间资源可以是周期性的，也就是说网络设备可以以固定周期向终端发送传输指示信号。
具体地，当传输指示信号通过PDSCH的DMRS传输时，传输指示信号的配置信息包括：PDSCH的DMRS所在OFDM符号和/或OFDM符号上的RB。例如该PDSCH的DMRS在传输信道带宽上对应OFDM符号上的部分或全部RB上进行传输。

其中，预设序列的生成参数与网络设备的信道占用时间COT的时间信息相关，时间信息包括：COT的起始时刻、持续时间和结束时刻中的至少一项。那么，终端可以根据预设序列的检测，获得网络设备当前传输的COT信息，如COT的起始时刻、持续时间和结束时刻等。
进一步地，网络设备在发送传输指示信号之后，即步骤101之后，还包括：向终端发送下行物理信号或下行物理信道，其中，下行物理信号或下行物理信道与传输指示信号的传输资源不重叠。假设网络设备调度的下行物理信号或下行物理信道资源和该传输指示信号占用的部分RE/RB资源相同，则下行物理信号或下行物理信道不在这些RE/RB上映射，以避免下行物理信号或下行物理信道与传输指示信号的传输资源发生重叠。其中，下行物理信道包括：物理下行广播信道PBCH、PDCCH和PDSCH中的至少一项。
