具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本发明实施例技术方案的说明，其本身没有特定的意义。因此，“模块”、“部件”或“单元”可以混合地使用。
需要说明的是，本发明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)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、长期演进(Long Term Evolution，LTE)系统及LTE系统的演进系统，例如先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统及NR系统的演进系统，例如免授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、或下一代通信系统等。
此外，本发明实施例的技术方案还可以应用于设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信。
可以理解地，上述通信系统可以应用于授权频谱，也可以应用于免授权频谱，例如2.4GHz，5GHz，37GHz或60GHz的频谱。
本发明实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。
当本发明实施例中的通信系统应用于免授权频谱，且布网场景是CA时，该CA布网场景可以是主载波在授权频谱上，辅载波在免授权频谱上，主载波和辅载波通过理想backhual连接。
当本发明实施例中的通信系统应用于免授权频谱，且布网场景是DC时，该DC布网场景可以是主载波在授权频谱上，辅载波在免授权频谱上，主载波和辅载波通过非理想backhual连接，其中，主载波上的系统可以和辅载波上的系统属于不同的系统，例如，主载波上的系统为LTE系统，辅载波上的系统为NR系统，或者，主载波上的系统也可以和辅载波上的系统属于相同的系统，例如，主载波和辅载波上的系统均为LTE系统或均为NR系统。
当本发明实施例中的通信系统应用于免授权频谱，且布网场景是SA时，终端设备可以通过免授权频谱上的系统接入网络。
不失一般性地，参见图1，其示出了非典型示例的通信系统1的结构示意，通信系统可以由终端设备10，12，14和网络设备20，终端设备与网络设备之间分别通过无线链路进行通信，如双向箭头所示。在图1中，终端设备10，12，14也可以称为用户设备(UE，User Equipment)、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。终端设备可以是无线局域网(Wireless Local Area Networks，WLAN)中的站点(STAION，ST)，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)设备、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、可穿戴设备以及下一代通信系统，例如，第五代通信(Fifth-Generation，5G)网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备等。在本发明实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。
网络设备20可以是用于与终端设备通信的设备，网络设备可以是WLAN中的接入点(Access Point，AP)，GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB，NB)，还可以是LTE中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及NR网络中的网络设备，例如5G基站(gNB)，或者未来演进的PLMN网络中的网络设备等。
在本发明实施例中，网络设备20为小区提供服务，终端设备10，12，14通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备20进行通信，该小区可以是网络设备20(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
在本发明实施例中，LTE系统或NR系统中的载波上可以同时有多个小区同频工作，在某些特殊场景下，也可以认为上述载波与小区的概念等同。例如在载波聚合(Carrier Aggregation，CA)场景下，当为UE配置辅载波时，会同时携带辅载波的载波索引和工作在该辅载波的辅小区的小区标识(Cell Indentify，Cell ID)，在这种情况下，可以认为载波与小区的概念等同，比如UE接入一个载波和接入一个小区是等同的。
基于图1所示的通信系统，在本发明实施例中，在NR系统中的公共信道和信号，比如同步信号(Synchronization Signal，SS)和物理广播信道(Physical Broadcast Channel，PBCH)，需要通过多波束扫描的方式覆盖整个小区，便于小区内的UE接收。其中，同步信号的多波束发送是通过定义SS/PBCH突发集合(SS/PBCH burst set)实现的，一个SS/PBCH burst set包含有一个或多个SS/PBCH块(SS/PBCH block)，一个SS/PBCH block用于承载一个波束的同步信号和物理广播信道；因此，一个SS/PBCH burst set可以包含小区内SS/PBCH block对应的N个波束的同步信号，SS/PBCH block的最大数目L与系统的频段有关。例如，当系统的频段不超过3GHz时，SS/PBCH block的最大数目L取值为4；当系统的频段处于3GHz和6GHz范围之内时，SS/PBCH block的最大数目L取值为8；当系统的频段处于6GHz和52.6GHz范围之内时，SS/PBCH block的最大数目L取值为64。
参见图2，其示出了本发明实施例提供的一种同步信号块的组成结构示意图；如图2所示，一个同步信号块(SS/PBCH block，SSB)中包括：一个主同步信号(Primary Synchronization Signal，PSS)201，一个辅同步信号(Secondary Synchronization Signal，SSS)202以及两个物理广播信道(New Radio Access Technology-Physical Broadcast Channel，NR-PBCH)，其中，两个物理广播信道分别为PBCH 203和PBCH 204。在一个SS/PBCH burst set内，所有的SSB在5ms的时间窗内发送，并且是以一定的周期重复发送，周期可以通过上层参数SSB-timing进行配置，包括5ms，10ms，20ms，40ms，80ms，160ms等，本发明实施例不作具体限定。
参见图3，其示出了本发明实施例提供的一种同步信号块的时隙分布示意图；在图3中，包括六种不同的子载波间隔(Subcarrier Spacing，SCS)和不同的同步信号块数量L所对应的时隙分布；举例来说，以SCS＝15kHz、L＝4为例，一个时隙(slot)包含14个符号(symbol)，可以承载两个同步 信号块；也就是说，在图3所示的5ms时间窗内，前两个时隙内分布有4个同步信号块。
为了让使用免授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，一些国家或地区规定了使用免授权频谱必须满足的法规要求。例如，在欧洲地区，通信设备遵循“先听后说”(listen-before-talk，LBT)原则，即通信设备在免授权频谱的信道上进行信号发送之前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在免授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。且为了保证公平性，在一次信号传输过程中，通信设备使用免授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupation Time，MCOT)。然而，在免授权频谱上使用NR技术实现数据传输，在SSB的发送过程中，由于存在LBT失败的可能，目前NR中定义的SSB的发送时间可能无法成功发送SSB，现有的解决方案是增加SSB的发送机会，定义新的SSB的发送时间作为备选，这样当由于LBT失败无法在一个发送时间发送SSB时，还可以在备选的发送时间发送SSB。
参见图4，其示出了本发明实施例提供的一种增加发送机会的原理示意图；如图4所示，当SSB index 0的发送时间之前所进行的LBT失败时，需要继续进行信道侦听，若在SSB index 2之前所进行的LBT成功，则可以从SSB index 2开始发送剩余的SSB，并在发送完SSB index 7之后，再接着发送之前没有发送成功的SSB index 0和SSB index 1；其中，SSB index 0和SSB index 1的实际发送时间为备选发送时间；这样，根据LBT成功的时刻，SSB的实际发送时间可能是目标发送时间(比如预定义的发送时间)，也可能是备选发送时间。
原则上，增加SSB的发送机会越多，对SSB的成功发送越有利；但是增加SSB的发送机会的同时，还会增加SSB的发送窗口长度；由于终端设备是根据预先配置的窗口(比如SMTC窗口)进行SSB的测量，如果SSB的发送窗口长度增加，为了测量这些SSB的发送位置，此时需要配置较大的SMTC窗口，这样会对终端的测量造成不利影响，比如节电、异频测量的传输中断时间长度等；在本发明实施例中，为了使得在尽可能地增加同步信号块发送机会的同时，还能够减少对终端测量的影响，下面将结合附图对本发明各实施例进行详细说明。
实施例一
参见图5，其示出了本发明实施例提供的一种信号传输的方法流程，该方法可以应用于前述通信系统的终端设备中，所述方法可以包括：
S501：确定同步信号块的发送时间集合；其中，所述发送时间集合是根据下述各项中至少一项：时间窗口的大小、所述同步信号块的子载波间隔和所述同步信号块的数量确定的；
S502：基于所述发送时间集合，接收网络设备发送的所述同步信号块。
基于图5所示的技术方案，应用于终端设备，通过确定同步信号块的发送时间集合；其中，所述发送时间集合是根据下述各项中至少一项：时间窗口的大小、所述同步信号块的子载波间隔和所述同步信号块的数量确定的；基于所述发送时间集合，接收网络设备发送的所述同步信号块。由于在确定同步信号块的发送机会时，还考虑了时间窗口的大小、同步信号块的子载波间隔和同步信号块的数量这些参数的影响，可以使得在尽可能地增加同步信号块发送机会的同时，还能够减少对终端测量的影响。
可以理解地，根据时间窗口的大小、同步信号块的子载波间隔和同步信号块的数量等这些参数信息，可以确定出同步信号块的发送时间集合，这里，发送时间集合是用于表征能够将同步信号块进行发送的所有可能存在的发送时间；因此，对于图5所示的技术方案，在一种可能的实现方式中，所述发送时间集合包括至少一个第一发送时间和一个第二发送时间，所述第二发送时间用于表征目标发送时间，所述至少一个第一发送时间用于表征除所述第二发送时间之外的备选发送时间。
在上述实现方式中，具体地，所述确定同步信号块的发送时间集合，包括：
根据所述同步信号块的子载波间隔和所述同步信号块的数量，在所述时间窗口内获取至少一个第一发送时间；
根据所述至少一个第一发送时间，确定出所述同步信号块的发送时间集合。
需要说明的是，第一发送时间可以有多个，它是根据终端设备额外增加的发送机会得到的，为了使得同步信号块能够成功发送，需要尽可能地得到更多的发送机会，比如获取最大数量的第一发送时间，这些发送时间也可以称之为备选发送时间；第二发送时间有一个，它是根据终端设备预定义的发送时间得到的，第二发送时间也可以称之为目标发送时间。
在本发明实施例中，第一发送时间越多，表示同步信号块的发送机会就越多。为了成功发送同步信号块，终端设备可以有很多次发送机会，这些所有可能存在的发送机会所对应的发送时间组成了发送时间集合；其中，这些发送机会并不是随意确定的，它主要和时间窗口的大小、所述同步信号块的子载波间隔和所述同步信号块的数量等参数信息有关。在确定出发送时间集合之后，终端设备可以接收网络设备所发送的同步信号块；这里，同步信号块的实际发送时间可以是目标发送时间，也可以是备选发送时间中的一个或多个；具体地，针对同步信号块的实际发送时间，则是由网络设备通过信道侦听以及信道抢占等情况实际得到的，本发明实施例对此不作具体限定。
以图3所示的同步信号块的时隙分布为例，在参数SCS和L取值不同的情况下，SSB在5ms时间窗口内的时隙分布是不同的。假定时间窗口(比 如SMTC窗口)配置为5ms，在该SMTC窗口内，需要尽可能地增加SSB的发送机会，根据SMTC窗口的大小、SCS和L的不同参数信息，所得到SSB的发送机会是不同的，这些SSB所有可能存在的发送机会所对应的发送时间组成了发送时间集合。
参见图6，其示出了本发明实施例提供的一种基于不同参数信息所增加发送机会的分布示意图；在图6中，仍以时间窗口(比如SMTC窗口)配置为5ms为例，在该SMTC窗口内，针对SCS和L的不同参数信息，SSB所确定的发送机会是不同的；其中，针对灰色填充图案所对应的发送时间为预定义的发送时间，也即第二发送时间；除灰色填充图案之外的其他填充图案，这些其他填充图案所对应的发送时间为备选发送时间，即第一发送时间；另外，这些其他填充图案用于代表SSB所增加的发送机会，填充图案的种类越多，代表SSB所增加发送机会的次数越多；比如对于SCS＝30kHz、L＝4的配置信息，SSB可以增加4次发送机会；对于SCS＝15kHz、L＝8的配置信息，SSB没有增加发送机会；对于SCS＝240kHz、L＝64的配置信息，SSB增加了1次发送机会。
对于图5所示的技术方案，在一种可能的实现方式中，所述时间窗口包括预定义的时间窗口或者由网络设备配置的测量时间窗口。
在上述方案中，具体地，在所述基于所述发送时间集合，接收网络设备发送的所述同步信号块之后，所述方法还包括：
若所述时间窗口为测量时间窗口时，对所述同步信号块进行信号测量。
需要说明的是，在本发明实施例中，时间窗口可以是预先定义的窗口，也可以是由网络设备配置的测量时间窗口，而且时间窗口的大小可以根据实际需求进行具体设定，比如5ms、8ms或者10ms等，本发明实施例对此均不作具体限定。
以图6为例，该时间窗口的大小为5ms，即半帧的时间长度；在图6中，由于SSB所增加的发送机会均是在该5ms的时间窗口内进行的，并没有配置更大的时间窗口，所以终端设备对SSB的信号测量仍然是在这个5ms的时间窗口内进行测量，并不会导致终端的测量产生不利影响。
对于图5所示的技术方案，在一种可能的实现方式中，所述同步信号块的数量包括预定义的所述同步信号块数量或者实际发送的所述同步信号块数量。
需要说明的是，同步信号块的最大数量与系统的频段有关；比如当系统的频段不超过3GHz时，SS/PBCH block的最大数目L取值为4；当系统的频段处于3GHz和6GHz范围之内时，SS/PBCH block的最大数目L取值为8；当系统的频段处于6GHz和52.6GHz范围之内时，SS/PBCH block的最大数目L取值为64。这里，同步信号块的数量可以是预定义的同步信号块数量，也可以是实际发送的同步信号块数量，本发明实施例不作具体限定；仍以图6为例，在图6中，同步信号块的数量L的取值可以是4，也可 以是8，还可以是64，针对L的不同取值，图6给出了在L和SCS的不同参数信息下，SSB分别对应增加的发送机会。
对于图5所示的技术方案，在一种可能的实现方式中，所述同步信号块的子载波间隔包括预定义的子载波间隔或者由网络设备配置的子载波间隔。
需要说明的是，在通信系统中，对于同步信号块的子载波间隔一般包括有一种或多种配置，比如15kHz、30kHz、120kHz、240kHz等，具体的，子载波间隔可以是预定义的，也可以是由网络设备配置的；其中，子载波间隔还可以是网络设备通过信令指示的，甚至还可以是根据物理随机接入信道的子载波间隔所确定的，在本发明实施例中，对此不作具体限定。
仍以图6为例，该时间窗口的大小为5ms，根据不同的配置信息，比如若SCS＝30kHz、L＝4，则SSB可以增加4次发送机会，这样也就增大了将SSB成功发送的概率；若SCS＝15kHz、L＝4，则SSB可以增加1次发送机会，这样也会增大SSB成功发送的概率；由于SSB所增加的发送机会均是在该5ms的时间窗口内进行的，并没有配置更大的时间窗口，也就不会对终端的测量产生不利影响；在本发明实施例中，由于在确定同步信号块的发送机会时，还考虑了时间窗口的大小、同步信号块的子载波间隔和同步信号块的数量这些参数的影响，可以使得在尽可能地增加同步信号块发送机会的同时，还能够减少对终端测量的影响。
本实施例提供了一种信号传输的方法，通过确定同步信号块的发送时间集合；其中，所述发送时间集合是根据下述各项中至少一项：时间窗口的大小、所述同步信号块的子载波间隔和所述同步信号块的数量确定的；基于所述发送时间集合，接收网络设备发送的所述同步信号块；从而可以在尽可能地增加同步信号块的发送机会的同时，还能够减少对终端测量的影响。
