Description

信号传输的方法和通信装置
本申请要求于2020年11月13日提交中国国家知识产权局、申请号为202011270400.6、申请名称为“信号传输的方法和通信装置”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，并且具体地，涉及一种信号传输的方法和通信装置。
背景技术
移动业务的发展对无线通信的数据速率和效率要求越来越高。波束成形技术用来将传输信号的能量限制在某个波束方向内，从而增加信号和接收的效率。波束成形技术能够有效扩大无线信号的传输范围，降低信号干扰，从而达到更高的通信效率和获取更高的网络容量。然而，在采用波束成形技术的通信网络中，首先需要将发送波束和接收波束匹配，使得发送端到接收端的增益最大，否则无法获取比较高的通信效率。而且为了达到全覆盖，要求基站端波束进行扫描。因此现有5G协议中，支持基站发送多个同步信号块(synchronization signal and PBCH block，SSB)，每个SSB可以用不同的波束进行发送，从而保证整个覆盖区域都能接收到SSB。也就是整个区域的终端都能够接入网络。
参见图1，图1是现有SSB组成方式的示意图。SSB由主同步信号(primary synchronization signals，PSS)、辅同步信号(secondary synchronization signals，SSS)、物理广播信道(physical broadcasting channel，PBCH)三部分共同组成。5G通信协议中规定一个SSB占用4个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，其中PSS占用一个符号，SSS占用一个符号，PBCH占用3个符号(和SSS共用其中一个符号)。参见图2，图2是SSB在一个时隙中所在的OFDM符号位置的示意图。如图2所示，第一个SSB在第5～8个OFDM符号上发送，第二个SSB在第9～12个OFDM符号上发送。
由于和SSB频分的频域资源，不能够用来给终端设备传输数据，主要原因是终端设备做小区测量的时候，会通过扫描接收波束的方式接收SSB，因此不能用特定的接收波束来接收SSB，进而也无法用特定的接收波束来接收和SSB同一时刻发送的不同频域资源的数据，这样就会造成资源开销大。

为便于理解本申请实施例，首先结合图3详细说明适用于本申请实施例的通信系统。该通信系统可以包括至少一个网络设备和至少一个终端设备。网络设备与终端设备可通过无线链路通信。单个网络设备可以向单个或多个终端设备传输数据或控制信令，多个网络设备也可以同时为单个终端设备传输数据或控制信令。
本申请实施例中，网络设备可以是任意一种具有无线收发功能的设备。网络设备包括但不限于：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)、家庭基站(例如，home evolved Node B，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 point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G(如NR)系统中的gNB或传输点(TRP或TP)，或者，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，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(distributed unit，DU)等，或者，还可以为卫星或者卫星信关站等。
本申请实施例中的网络设备也可以是指集中单元(central unit，CU)或者分布式单元(distributed unit，DU)，或者，网络设备也可以是CU和DU组成的。CU和DU可以理解为是对基站从逻辑功能角度的划分。其中，CU和DU在物理上可以是分离的，也可以部署在一起，本申请实施例对此不做具体限定。一个CU可以连接一个DU，或者也可以多个DU共用一个CU，可以节省成本，以及易于网络扩展。CU和DU的切分可以按照协议栈切分，其中一种可能的方式是将无线资源控制(radio resource control，RRC)、业务数据适配协议栈(service data adaptation protocol，SDAP)以及分组数据汇聚协议(packet data convergence protocol，PDCP)层部署在CU，其余的无线链路控制(radio link control，RLC)层、介质访问控制(media access control，MAC)层以及物理层部署在DU。本发明中并不完全限定上述协议栈切分方式，还可以有其它的切分方式，具体可以参考TR38.801v14.0.0。CU和DU之间通过F1接口连接。CU代表gNB通过Ng接口和核心网连接。
本申请实施例中的网络设备又可以是指集中式单元控制面(CU-CP)节点或者集中式单元用户面(CU-UP)节点，或者，网络设备也可以是CU-CP和CU-UP。其中CU-CP负责控制面功能，主要包含RRC和PDCP-C。PDCP-C主要负责控制面数据的加解密，完整性保护，数据传输等。CU-UP负责用户面功能，主要包含SDAP和PDCP-U。其中SDAP主要负责将核心网的数据进行处理并将flow映射到承载。PDCP-U主要负责数据面的加解密，完整性保护，头压缩，序列号维护，数据传输等。其中CU-CP和CU-UP通过E1接 口连接。CU-CP代表gNB通过Ng接口和核心网连接。通过F1-C(控制面)和DU连接。CU-UP通过F1-U(用户面)和DU连接。当然还有一种可能的实现是PDCP-C也在CU-UP。需要说明的是，CU可以被划分为接入网设备，也可以被划分为核心网(core network，CN)设备，本申请对此不做限定。

此外，终端设备还可以是物联网(internet of things，IoT)系统中的终端设备。IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。
为便于理解本申请实施例，首先对本申请中涉及到的术语作简单说明。
1、同步信号(Synchronization Signal，SS)：SS可以包括PSS和SSS，同步信号用于终端设备和网络侧实现时频同步，以及小区物理标识符(ID)的检测。其中，PSS用于终端时频同步以及检测小区，SSS用于传输小区物理标识ID，也可以将PSS和SSS和在一起，实现上述功能。
2、PBCH：用于传输系统信息。
3、SSB：包括SS和PBCH，用于终端设备和网络侧实现时间同步，小区物理标识符(ID)的检测以及获取系统信息。现有技术的SSB组成方式如图1所示，在时域中，SSB由4个OFDM符号组成，在SSB内从0到3递增的顺序进行编号。在频域上，SSB由240个连续的子载波组成，子载波编号从0到239顺序递增。PSS时域上位于SSB块中第0个OFDM符号的位置，频域占据第56到182之间的126个子载波。SSS时域上位于SSB块中第2个OFDM符号的位置，频域占据第56到182之间的126个子载波。PBCH占用SSB块中第1个和第3个OFDM符号位置时，频域占据第0到239之间的240个子载波； PBCH占用SSB块中第2个符号位置时，频域占据第0到47以及第192到239之间的96个子载波。PBCH信号与其所对应的DMRS信号之间采用频率复用方式，其中每隔4个子载波存在1个DMRS信号。

下面详细介绍本申请的技术方案。
参见图4，图4是本申请提供的一种信号传输的方法的示意性流程图。
S401、网络设备确定第一SSB的组成方式。
应理解，SSB中SS和PBCH的组成方式可以有多种，网络设备可以根据实际情况以其中一种SSB组成方式作为第一SSB的组成方式。例如：网络设备可以根据运营商的实际带宽确定所述第一SSB的组成方式。
可选的，SS和PBCH以频分或者时分或者时频分的方式组成SSB。其中，时频分是指SS和PBCH的组成方式中既有时分又有频分，下面的实施例中会进行举例说明。
作为示例，首先以宽带SSB为例进行说明，即SSB中的PBCH和SS采用频分或频分为主的组合方式，该SSB组合方式可以提升SSB的带宽，降低SSB占用的符号个数，从而降低系统的资源开销。
下面，给出一些宽带SSB的组成方式。参见图5，图5是本申请提出的三种不同的宽带SSB的组成方式的示意图。
①图5的(a)是SS占据连续符号的可能实现方式的示意图，图a的SSB可以占据1个或者2个或者3个符号。
②图5的(b)是SS不占据连续符号且部分PBCH在SS的频率上面或者下面的可能实现方式示意图，可以看出，图b的SSB需要占据3个符号。
③图5的(c)是SS占据连续符号且部分PBCH在SS的频率上面或者下面的可能实现方式示意图，可以看出，图c的SSB可以占据1个或者2个符号。
应理解，宽带SSB的组成方式不限于以上举例的三种类型，还可以有其他类型的组成方式，本申请不再一一举例。
可选的，SS可以占据连续的符号(例如图5的(a)、图5的(c))，也可以占据非连续的符号(例如图5的(b))。
需要说明的是，由于运营商的带宽分配相对于SS的频点位置可上可下，因此，PBCH相对于SS的频率位置可上可下。
可选的，全部PBCH的频率在SS的频率上面(例如图5的(a)中运营商1带宽)或者全部PBCH的频率在SS的频率下面(例如图5的(a)中运营商2带宽)，也可以部分PBCH的频率在SS的频率上面或者下面(例如图5的(b)、(c))。
由上可以看出，该宽带SSB的组成方式降低了现有SSB占用的符号个数，降低了系统开销，还可以保证兼容不同运营商分配的不同的频段。
上述宽带SSB组成方式中，PBCH相对于SS的位置主要是频分的位置不同。在实际中，如果运营商的最小带宽小于上述实施例中SS和PBCH的带宽之和，那么运营商提供的带宽将无法发送一个完整的SSB，从而导致终端设备无法接入。
因此，如果考虑运营商最小带宽的要求，本申请给出另一种SSB组成方式，即PBCH和SS存在时分的可能，也就是占用多个OFDM符号，但是SSB所占用的带宽为窄带(相比于图5对应的带宽SSB)。以窄带SSB为例进行说明，PBCH和SS采用时分或时分为主的组合方式。
下面，给出一些窄带SSB的组成方式。参见图6，图6是本申请提出的六种不同的窄带SSB的组成方式的示意图。
应理解，窄带SSB存在时分的组成方式不限于图6中的六种类型，还可以有其他类型的组成方式，本申请不再一一举例。
可选的，SS可以占据连续的符号(例如图6的(a)-(c))。
可选的，SS可以占据非连续的符号(例如图6的(d)-(f))。
可选的，全部SS和PBCH时分&频分(如图6的(b)和(e))，也可以部分SS与PBCH时分&频分(如图6的(c)和(f))。
可以看出，为了保证足够小的SSB带宽，窄带SSB占据的符号相对于宽带SSB占据的符号更多。例如：占据1个符号的宽带SSB和占据2个符号的窄带SSB，占据2个符号的宽带SSB和占据3个符号的窄带SSB，占据3个符号的宽带SSB和占据4个符号的窄带SSB。
应理解，为了兼容运营商最小带宽的要求，在实际应用中，网络设备发送的SSB的 组成方式不仅可以有如图5所示的宽带SSB组成方式一种或者多种，也可以有如图6所示的窄带SSB组成方式的一种或者多种。
S402、网络设备发送第一SSB，并通过第一信息向终端设备指示第一SSB的部分或全部组成方式。
对应的，终端设备接收网络设备发送的第一SSB。
其中，第一信息中包含第一SSB的部分或全部组成方式的信息，S403中会对第一信息可能的几种具体实现方式进行具体的介绍，这里暂不展开叙述。
现有技术中，终端设备在接收到SSB后通过检测SSB中的SS实现时频同步、获取小区ID等功能，进一步解调出PBCH传输的系统信息。由于SSB的组成方式是固定的，终端设备可以直接根据已知的SSB组成方式解调出PBCH中传输的系统消息，而本申请中由于SSB的组合方式是可变的，即不是唯一的，因此，终端设备在接收到SSB之后需要首先要确定SSB的组成方式。
S403、终端设备通过盲检第一SSB中PBCH的位置和/或通过检测第一信息，确定所述第一SSB的组成方式。
作为示例而非限定，本申请给出以下几种确定第一SSB组成方式的方法。
可选的，PBCH盲检的方式：终端设备在接入小区的时候，先检测出SS，然后根据PBCH可能的位置，通过检测PBCH的解调参考信号(demodulation reference signal，DMRS)或者通过检测PBCH的传输内容来确定PBCH相对于SS的具体位置，以及解调出PBCH传输的系统信息。这种方法虽然增加了UE检测的复杂度，但是无需任何额外信息传输。
可选的，网络设备通过SS(即第一信息的一例)携带指示信息。例如，网络设备通过不同的SS序列进行指示，终端设备通过检测出的SS的序列，从而确定第一SSB的全部或者部分组成方式。
可选的，网络设备通过PSS和SSS的相对位置(即第一信息的另一例)来隐式携带指示信息。例如通过PSS在SSS之前，或者PSS在SSS之后来传递指示信息。终端设备通过检测出PSS和SSS的具体位置，从而得知第一SSB的全部或者部分组成方式。
可选的，网络设备通过新的参考信号(reference signal，RS)(即第一信息的又一例)携带指示信息。例如，通过RS携带的不同序列进行指示。终端设备通过检测出RS的序列，从而得知第一SSB的全部或者部分组成方式。进一步的，新的RS可以同时传输其他信息，例如第一SSB的序号等。
可选的，网络设备通过运营商提供的客户识别模块(subscriber identity module，SIM)卡(即第一信息的又一例)提供第一SSB的组成方式。终端设备通过读取SIM卡的信息获取第一SSB的组成方式。可选的，当终端设备的漫游开关关闭的时候，终端设备通过此方式获取第一SSB的组成方式。当漫游开关打开的时候，终端设备可通过上述其他方式进行获取第一SSB的组成方式。在没有其他指示信息通知的情况下，通过PBCH的盲检获取SSB的组成方式。上述几种携带指示信息的方法相比于盲检的方式，在提升系统信息传输开销的情况下，却降低UE检测的复杂度。
可选的，终端设备也可以通过上述方式中的多个方式共同确定第一SSB的组成方式，也就是说多个方式中的每一种方式可以指示第一SSB组成方式的部分信息，终端设备通过多种方式各自提供的部分信息共同确定第一SSB组成方式。例如，网络设备通过SS显 示的携带指示信息指示第一SSB的组成是宽带SSB还是窄带SSB，终端设备通过PBCH的盲检进一步检测该宽带SSB或者窄带SSB的明确组成方式。
可选的，对于已接入小区的终端设备，也可以对相邻小区进行测量，因此网络设备可以通知终端设备相邻小区的SSB组成方式。例如：网络设备可以通过系统消息、RRC信令、MAC信令，物理下行控制信道(physical downlink control channel，PDCCH)等向终端设备进行通知。
可选的，为了降低终端设备检测的复杂度，同频测量下，邻区SSB的组成方式和终端设备的驻留小区(或者服务小区)的SSB的组成方式相同，因此同频测量网络设备不需要通知SSB的组成方式。在异频测量下，终端设备最多测量N种不同的组成方式，其中，N为正整数，可选的，N可以作为能力上报，或者固定一个默认值。
