Abstract

本申请实施例提供一种无线通信方法、通信装置及通信系统。该方法中，终端根据检测到的SSB确定SSB在第一集合中的第一索引和第二索引，然后确定该SSB的资源。由于一个SSB可以对应一个或多个资源，且不同资源之间可以时分复用，因此一个SSB有多种发送时机。由于每个SSB对应一个波束发送方向，因而对应某个波束发送方向的SSB的发送时机是可以灵活调整的。在发送一个集合中的多个SSB时，可以根据业务需求确定对应不同波束发送方向的各个SSB的先后发送顺序，进而确定各个SSB占用的资源。该方法可以实现一个集合中的多个SSB在不同的波束上的灵活发送，可以提升SSB发送时被终端检测到的可能性，从而减少资源浪费。

具体实施方式
图1是本申请实施例应用的通信系统1000的架构示意图。如图1所示，该通信系统包括无线接入网100和核心网200，可选的，通信系统1000还可以包括互联网300。其中，无线接入网100可以包括至少一个无线接入网设备(如图1中的110a和110b)，还可以包括至少一个终端(如图1中的120a-120j)。终端通过无线的方式与无线接入网设备相连，无线接入网设备通过无线或有线方式与核心网连接。核心网设备与无线接入网设备可以是独立的不同的物理设备，也可以是将核心网设备的功能与无线接入网设备的逻辑功能集成在同一个物理设备上，还可以是一个物理设备上集成了部分核心网设备的功能和部分的无线接入网设备的功能。终端和终端之间以及无线接入网设备和无线接入网设备之间可以通过有线或无线的方式相互连接。图1只是示意图，该通信系统中还可以包括其它网络设备，如还可以包括无线中继设备和无线回传设备，在图1中未画出。
无线接入网设备可以是基站(base station)、演进型基站(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、5G移动通信系统中的下一代基站(next generation NodeB，gNB)、第六代(6th generation，6G)移动通信系统中的下一代基站、未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等；也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。无线接入网设备可以是宏基站(如图1中的110a)，也可以是微基站或室内站(如图1中的110b)，还可以是中继节点或施主节点等。本申请的实施例对无线接入网设备所采用的具体技术和具体设备形态不做限定。在本申请的实施例中，以基站作为无线接入网设备的一个举例进行描述。
终端也可以称为终端设备、用户设备(user equipment，UE)、移动台、移动终端等。终端可以广泛应用于各种场景，例如，设备到设备(device-to-device，D2D)、车物(vehicle to everything，V2X)通信、机器类通信(machine-type communication，MTC)、物联网(internet of things，IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智 能家具、智能办公、智能穿戴、智能交通、智慧城市等。终端可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、车辆、无人机、直升机、飞机、轮船、机器人、机械臂、智能家居设备等。本申请的实施例对终端所采用的具体技术和具体设备形态不做限定。
基站和终端可以是固定位置的，也可以是可移动的。基站和终端可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和人造卫星上。本申请的实施例对基站和终端的应用场景不做限定。
基站和终端的角色可以是相对的，例如，图1中的直升机或无人机120i可以被配置成移动基站，对于那些通过120i接入到无线接入网100的终端120j来说，终端120i是基站；但对于基站110a来说，120i是终端，即110a与120i之间是通过无线空口协议进行通信的。当然，110a与120i之间也可以是通过基站与基站之间的接口协议进行通信的，此时，相对于110a来说，120i也是基站。因此，基站和终端都可以统一称为通信装置，图1中的110a和110b可以称为具有基站功能的通信装置，图1中的120a-120j可以称为具有终端功能的通信装置。
基站和终端之间、基站和基站之间、终端和终端之间可以通过授权频谱进行通信，也可以通过免授权频谱进行通信，也可以同时通过授权频谱和免授权频谱进行通信；可以通过6千兆赫兹(gigahertz，GHz)以下的频谱进行通信，也可以通过6GHz以上的频谱进行通信，还可以同时使用6GHz以下的频谱和6GHz以上的频谱进行通信。本申请的实施例对无线通信所使用的频谱资源不做限定。
在本申请的实施例中，基站的功能也可以由基站中的模块(如芯片)来执行，也可以由包含有基站功能的控制子系统来执行。这里的包含有基站功能的控制子系统可以是智能电网、工业控制、智能交通、智慧城市等上述应用场景中的控制中心。终端的功能也可以由终端中的模块(如芯片或调制解调器)来执行，也可以由包含有终端功能的装置来执行。
在本申请中，基站向终端发送下行信号或下行信息，下行信息承载在下行信道上；终端向基站发送上行信号或上行信息，上行信息承载在上行信道上。终端为了与基站进行通信，需要与基站控制的小区建立无线连接。与终端建立了无线连接的小区称为该终端的服务小区。当终端与该服务小区进行通信的时候，还会受到来自邻区的信号的干扰。
在本申请的实施例中，时域符号可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，也可以是离散傅里叶变换扩频OFDM(Discrete Fourier Transform-spread-OFDM，DFT-s-OFDM)符号。如果没有特别说明，本申请实施例中的符号均指时域符号。
可以理解的是，本申请的实施例中，物理下行共享信道(physical downlink shared channel,PDSCH)、物理下行控制信道(physical downlink control channel，PDCCH)、物理上行共享信道(physical uplink shared channel，PUSCH)和物理广播信道(physical broadcast channel，PBCH)只是作为下行数据信道、下行控制信道、上行数据信道和广播信道一种举例，在不同的系统和不同的场景中，数据信道、控制信道和广播信道可能有不同的名称，本申请实施例对此并不做限定。
4GLTE系统中，系统基本参数、帧结构以及信号的时频资源设计相对比较固定。具体的：
第一，系统基本参数和帧结构方面，4G LTE系统仅支持固定15千赫兹(kilohertz，KHz)的子载波间隔(subcarrier spacing，SCS)。一个无线帧包括10个子帧，每个子帧对于正常循环前缀时包括14个OFDM符号(下面简称符号)，时域调度粒度为一个子帧。载波带宽只支持有限的几种，具体包括1.4兆赫兹(megahertz，MHz)、3MHz、5MHz、10MHz、15MHz、20MHz这6种带宽，频率调度粒度为12个子载波，即一个资源块(resource block，RB)的带宽。该RB为基本的时频调度单元，具体包括时域的1个子帧和频率的12个子载波组成的时频两维资源，其中一个符号的一个子载波为最小的时频资源，称为资源单元(resource element，RE)，即1个RB包括12x14个RE。
第二，信号的时频资源方面，一个子帧中，用于初始接入的信号处于载波中心的6个RB的带宽内，包括主同步信号(primary synchronization signal，PSS)、辅同步信号(secondary synchronization signal，SSS)和PBCH。参考图2，为4G LTE系统中的信号/信道的时频资源位置示意图。终端接收到PBCH后，才能获取到载波带宽。PSS和SSS发送周期为5个子帧，PBCH发送周期为10个子帧。无论是否存在数据传输，每个子帧中的每个RB上都需要发送小区特定参考信号(cell-specific reference signal，CRS)，用于测量、信道估计、解调和时频跟踪等功能。PDCCH用于上下行数据信道和公共信息的调度，具体通过时频交织的方式被打散到整个载波带宽上，时域位于一个子帧的前n个符号内，n为1-4中的自然数之一。在本申请中，公共信息可以包括系统信息块(system information block，SIB)、随机接入信道(random access channel，RACH)应答、寻呼消息等。
5G NR系统中，系统基本参数、帧结构以及信号的时频资源设计相对比较灵活。具体的：
第一，系统基本参数和帧结构方面，5G NR系统支持多种SCS，具体对于频率范围1(一般认为6GHz以下)，支持15/30/60KHz的SCS；对于频率范围2(一般认为6GHz以上)，支持60KHz和120KHz的SCS。一个无线帧包括10个子帧，每个子帧的时长是1毫秒(ms)。NR系统的时域调度粒度定义为时隙，每个时隙对于正常循环前缀时包括14个OFDM符号(下面简称符号)。因此，对于不同的SCS，1个子帧中包括的时隙数是不同的，比如对于15KHz SCS，1个子帧包括1个时隙；对于30KHz SCS，1个子帧包括2个时隙，每个时隙的时长是0.5ms。NR通信系统支持灵活的载波带宽，即不限制载波带宽只有LTE系统的有限几种，频域的基本调度粒度也为12个子载波。
第二，信号的时频资源方面，NR系统中用于初始接入的信号称为同步信号/广播信道块(synchronization signal/PBCH block，SSB)，该SSB包括PSS、SSS和PBCH。SSB在载波中的频域位置是灵活的，即不需要如LTE系统那样被限制必须位于载波中心。NR系统引入带宽部分(bandwidth part，BWP)的概念，将系统级别的载波和终端级别的BWP解耦，比如NR系统可以支持100MHz带宽的载波，但终端可以只支持其中的某个20MHz的BWP接收能力。时域周期方面，NR支持多种SSB发送周期，在初始接入阶段终端假设SSB发送周期为20ms，即两个无线帧的时长。为了提升覆盖，NR系统中对公共信道引入了波束赋形机制，并通过对多个SSB进行波束发送的方式来实现全向覆盖。此外，NR系统很大程度上取消了一直存在的信号发送(比如LTE系统中无论是否存在数据传输，每个子帧的每个RB上都需要发送一直存在的CRS)，取而代之的是通过功能解耦的方式引入相应功能的参考信号(reference signal，RS)，比如高层测量用SSS或信道状态信息参考信 号(channel state information-reference signal，CSI-RS)、信道估计用CSI-RS或解调用解调参考信号(demodulation reference signal，DMRS)等，每种功能的RS按需配置和发送。PDCCH还是用于上下行数据信道和公共信息的调度，但不需要一定通过时频交织的方式被打散到整个载波带宽上，而是可以在载波中的一部分RB的频域资源内发送，该部分RB称为控制资源集(conntrol resource set，CORESET)。PDCCH在时域的检测位置由搜索空间配置来确定，也不像LTE系统那样，每个子帧都需要检测PDCCH。
总结下来，5G NR通信系统相比4G LTE，在系统设计方面提供了更多的灵活性，包括基本参数、帧结构以及信道的时频资源设计等，可以更好的支持前向兼容和可扩展性。
NR系统中，终端的初始接入流程主要包括：
首先，检测PSS和SSS做到与NR系统的时频同步，并获取物理小区标识；
然后，接收PBCH中的主信息块(master information block，MIB)，获取NR系统的必要系统信息，包括初始BWP以及调度公共信道的PDCCH的时频资源配置(包括频域CORESET和时域搜索空间的资源配置)等；
然后，接收SIB1，获取除MIB中系统信息之外的必要系统信息，包括RACH配置、时分双工(time division duplexing，TDD)帧结构配置等；
然后，终端检测系统寻呼消息，或者终端发送随机接入来与基站建立无线资源控制(radio resource control，RRC)连接；
RRC连接成功建立后，终端和基站就可以进行正常的数据传输了。
为实现初始接入的公共信道的全向覆盖，NR采用波束赋形机制，通过将多个SSB在多个波束方向上采用时分复用(time division multiplexing，TDM)的方式发送，这种发送方式可以称为公共信号发送方式或公共信号波束扫描发送方式，这里的公共信号包括SSB。针对待发送的多个SSB，该多个SSB采用TDM的资源复用方式，并且各个SSB的资源位置是固定的。参考图3，为5G NR系统中SSB的资源位置示意图。其中，在一个SSB周期内，支持以TDM方式发送一套SSB波束，该一套SSB波束由SSB索引号代表，比如对于3GHz～6GHz频段部署的NR系统，该一套SSB包括SSB索引#0、#1、…、#7的8个SSB波束。SSB的频域位置比较灵活，只需要在预先定义好的某频率栅格上即可。对于时域位置，该套SSB位于某个无线帧的前半帧内，且每个SSB的时域位置是固定的。参考图3，以30KHz SCS为例，该8个SSB位于前半帧的前4个时隙中，具体的符号位置也是如图3所示的固定位置。针对该发送的多个SSB，该多个SSB的波束发送方向不同，且按照固定的顺序进行发送。以图3所示的8个SSB为例，SSB0至SSB7的波束方向分别为方向1至方向8，在发送该8个SSB时，发送顺序依次为：在方向1发送SSB0，在方向2发送SSB1，在方向3发送SSB2，在方向4发送SSB3，在方向5发送SSB4，在方向6发送SSB5，在方向7发送SSB6，在方向8发送SSB7。因此，多个SSB分别占用固定的资源，基站按照固定方向在相应的资源上发送该多个SSB的波束。
除SSB采用波束扫描发送方式外，在初始接入阶段用于调度公共信道(比如包括SIB1和其他SIB、寻呼消息等)的公共PDCCH也是通过类似的波束扫描发送方式进行发送的，该公共PDCCH的时频资源由频域的CORESET和时域的搜索空间共同确定。参考图4，为5G NR系统中SSB和初始公共PDCCH的资源复用方式示意图。其中，PDCCH用于调 度承载SIB的信道。对于频率范围1(Frequency Range 1，FR1)，NR仅支持SSB与PDCCH是TDM的，即模式1(pattern 1)；对于频率范围2(Frequency Range 2，FR2)，NR系统支持SSB与PDCCH进行TDM或频分复用(frequency division multiplexing，FDM)的复用方式，其中FDM又分为模式2(pattern 2)和模式3(pattern 3)。其中，FR1为450MHz至6000MHz，FR2为24250MHz至52600MHz。
基于上面描述的NR系统的初始接入机制，可以看出，目前的公共信号发送方式与帧结构具有固定的对应关系。并且，对于FR2，由于部署频率较高，会采用更多的天线阵子来实现更大的波束赋形增益，目前业界主流是采用模拟波束。对于模拟波束赋形机制，同一时刻，所有频域资源都只能采用相同的波束加权值，导致波束只能指向某一方向。参考图5，为公共信号无法在发送时刻进行波束方向的动态调度示意图。该示例中，发送的每个公共信号的波束按照一定顺序在不同方向进行扫描发送，并且每个公共信号的波束的发送的方向是固定的，每个公共信号占用的时频资源也是相对固定的。以公共信号2为例，当发送公共信号2的波束时，有可能在公共信号2的波束方向没有终端或终端数量较少，而在其它方向有终端或终端数量较多，但由于在当前时刻只能发送公共信号2，而公共信号2的波束方向是固定的，因而无法指向有终端或终端数量较多的方向，一方面导致有通信需求的终端无法得到服务，另一方面，导致该公共信号的波束的无效发送，造成资源浪费。
因此，如何实现公共信号的灵活发送，是本申请实施例要解决的问题。
为解决该问题，本申请实施例中，引入多种公共信号发送方式，每种公共信号发送方式对应一个公共信号集合，一个公共信号集合中包括多个公共信号，该多个公共信号中的每个公共信号对应一个波束发送方向。不同公共信号一般对应不同的波束发送方向。一种公共信号发送方式用于表示公共信号集合中的多个公共信号的先后发送顺序。基站可以根据业务需要，确定公共信号集合对应的公共信号发送方式，并根据该公共信号发送方式向终端发送该公共信号集合内的多个公共信号。终端可以检测到该多个公共信号中的一个或多个公共信号，并从检测到的公共信号内获取同步信号等信息。在本申请中，如果没有特殊说明，“集合”可以是“公共信号集合”的简称。
作为一种实现方法，本申请实施例可以根据不同的候选分组规则，对一个公共信号集合内的多个公共信号进行分组，得到一个或多个分组，每个分组对应一个资源集合，每个资源集合包括该多个公共信号对应的资源中的一个或多个资源，每个资源包括时域资源和/或频域资源。其中，同一分组内的公共信号共享同一个资源集合内的资源，也即一个组内的某个公共信号可以使用该组对应的资源集合内的任意资源，但一个资源在某一时刻只能分配给一个公共信号使用。
图6为一种分组规则示意图，该分组规则是将第一集合中的公共信号分为四组，其中第一集合包括公共信号0至公共信息7。如下所示：
组1：包括公共信号0和公共信号4，组1对应由资源1和资源5组成的资源集合1，在一次发送中，公共信号0对应资源1或资源5中的一个，公共信号4对应资源1或资源5中的另一个；
组2：包括公共信号1和公共信号5，组2对应由资源2和资源6组成的资源集合2，在一次发送中，公共信号1对应资源2或资源6中的一个，公共信号5对应资源2或资源 6中的另一个；
组3：包括公共信号2和公共信号6，组3对应由资源3和资源7组成的资源集合3，在一次发送中，公共信号2对应资源3或资源7中的一个，公共信号6对应资源3或资源7中的另一个；
组4：包括公共信号3和公共信号7，组4对应由资源4和资源8组成的资源集合4，在一次发送中，公共信号3对应资源4或资源8中的一个，公共信号7对应资源4或资源8中的另一个。
根据上述分组规则，可以得到第一集合对应的多种公共信号发送方式，该多种公共信号发送方式中的任意一种公共信号发送方式对应的公共信号发送顺序可以表述为：公共信号0或公共信号4中的一个，公共信号1或公共信号5中的一个，公共信号2或公共信号6中的一个，公共信号3或公共信号7中的一个，公共信号0或公共信号4中的另一个，公共信号1或公共信号5中的另一个，公共信号2或公共信号6中的另一个，公共信号3或公共信号7中的另一个。其中，每个公共信号对应一个波束发送方向，比如，公共信号0至公共信号7分别对应方向1至方向8。
作为示例，第一集合对应的公共信号发送方式包括公共信号发送方式1、公共信号发送方式2和公共信号发送方式3。
其中，公共信号发送方式1对应的公共信号发送顺序为：公共信号0，公共信号1，公共信号2，公共信号3，公共信号4，公共信号5，公共信号6，公共信号7，且为公共信号0分配资源1，为公共信号1分配资源2，为公共信号2分配资源3，为公共信号3分配资源4，为公共信号4分配资源5，为公共信号5分配资源6，为公共信号6分配资源7，为公共信号7分配资源8；
公共信号发送方式2对应的公共信号发送顺序为：公共信号0，公共信号5，公共信号2，公共信号3，公共信号4，公共信号1，公共信号6，公共信号7，且为公共信号0分配资源1，为公共信号5分配资源2，为公共信号2分配资源3，为公共信号3分配资源4，为公共信号4分配资源5，为公共信号1分配资源6，为公共信号6分配资源7，为公共信号7分配资源8；
公共信号发送方式3对应的公共信号发送顺序为：公共信号4，公共信号5，公共信号6，公共信号3，公共信号0，公共信号1，公共信号2，公共信号7，且为公共信号4分配资源1，为公共信号5分配资源2，为公共信号6分配资源3，为公共信号3分配资源4，为公共信号0分配资源5，为公共信号1分配资源6，为公共信号2分配资源7，为公共信号7分配资源8。
基站在向终端发送一个集合的多个公共信号时，可以根据业务需求及分组规则，灵活选择各个公共信号的发送时间，由于每个公共信号对应一个波束发送方向，不同公共信号一般对应不同波束发送方向，因而可以实现根据业务需求，在某个发送时刻选择对应某个波束发送方向的公共信号进行发送，从而有助于提升公共信号被终端检测到的概率，提高系统性能，减少资源浪费。这里所说的业务需求，可以是指在该公共信号的发送时刻，具体处于哪些位置的终端有传输需求，以及有传输需求的终端的数量有多少。基站可以选择指向有传输需求的终端的公共信号进行发送。
图7为公共信号波束灵活发送示意图。该示例中，第一集合包括公共信号0至公共信 号7，且分组规则与图6所示的示例中的分组规则相同。基站根据该分组规则，向终端发送第一集合中的公共信号0至公共信号7。并且，公共信号发送方式对应的公共信号发送顺序依次为：公共信号0，公共信号1，公共信号6，公共信号3，公共信号4，公共信号5，公共信号2，公共信号7。可以看到，在图7中第一个可以发送公共信号2或公共信号6的时刻(简称为时刻A)，基站选择了发送公共信号6，而在第二个可以发送公共信号2或公共信号6的时刻(简称为时刻B)，基站选择了发送公共信号2。这是因为：基站在时刻A，确定在公共信号6的波束所指向的方向的终端数量较多，因此基站决定发送公共信号6，而在时刻B，发送公共信号2。因此，基站可以基于业务需求，在发送时刻从对应的分组中灵活选择一个公共信号进行发送，以实现多个公共信号在不同波束上的灵活发送，提升公共信号被终端检测到的概率，提升通信效率。
本申请实施例中，基站向终端发送第一集合中的多个公共信号，该多个公共信号中被终端检测到的公共信号称为第一公共信号。第二公共信号是与第一公共信号关联的公共信号。本申请实施例中的第一公共信号和第二公共信号的实现方法，包括但不限于：
实现方法一，第一公共信号包括同步信号和广播信道，第二公共信号包括控制信道或承载系统信息的信道。
可选的，该同步信号包括PSS和SSS。广播信道可以是PBCH，用于承载MIB。控制信道可以是PDCCH，用于调度承载系统信息的信道，该系统信息可以包括SIB，这里的SIB可以包括SIB1。
实现方法二，第一公共信号包括同步信号，第二公共信号包括控制信道或承载系统信息的信道。
可选的，该同步信号包括PSS和SSS。控制信道可以是PDCCH，用于调度承载系统信息的信道，这里的系统信息可以是最小必要系统信息，最小必要系统信息包括MIB和SIB，这里的SIB可以包括SIB1。需要说明的是，这里的MIB或SIB的名称在未来技术演进中可能有其它名称。
本申请实施例提供的通信方法可以由终端或用于终端的部件(如芯片、装置等)，以及基站或用于基站的部件(如芯片、装置等)执行。为便于说明，以下描述中，以终端和基站执行该方法为例进行说明。
图8为本申请实施例提供的一种无线通信方法示意图。该方法包括以下操作：
801，基站获取第一集合。
该第一集合包括多个公共信号，该多个公共信号包括第一公共信号，该第一公共信号包括同步信号。该第一公共信号在该第一集合中的索引为第一索引，第一索引对应多个资源，第一公共信号的第二索引用于指示该多个资源中的一个资源，该资源包括时域资源和/或频域资源。第一集合可以是预定义的，例如由协议预定义。
其中，第一集合可以按照第一分组规则进行分组，第一分组规则可以是多个候选分组中的一个；或者，第一分组规则也可以是预定义的，即只有这一个分组规则；或者，也可以没有该分组规则，此时第一集合中的所有公共信号可以看做是一个分组。第一集合中的公共信号按照第一分组规则被分成至少一个分组，该至少一个分组中的每一个分组对应一个资源集合，该资源集合包括第一集合对应的多个资源中的至少一个资源。例如，前述图6可以是该第一分组规则的一个示例。
802，基站向终端发送第一集合中的公共信号。
基站在向终端发送第一集合中的公共信号时，可以根据业务需求及分组规则，从发送时刻对应的分组中灵活选择一个公共信号进行发送，一个分组可以对应多个发送时刻，该分组内的任意一个公共信号可以在该多个发送时刻中的任意一个发送时刻进行发送。由于每个公共信号对应一个波束发送方向，因而可以实现根据业务需求，在某个发送时刻选择对应某个波束发送方向的公共信号进行发送，从而有助于提升公共信号被终端检测到的概率，提高系统性能，减少资源浪费。图7是基站向终端发送第一集合中的公共信号的一个示例。
803，终端检测公共信号。
比如，终端对基站发送的公共信号进行检测，可以检测到发送的第一集合中的第一公共信号。
作为一种实现方法，终端可以根据同步信号的候选序列以及对应的SCS来检测同步信号。其中，候选序列可以由标准预先定义，比如用统一的PSS和SSS的候选序列，或者也可以为每个频段预定义一套候选序列，不同频段对应的候选序列可以相同也可以不同，比如频段1用第一套候选序列，频段2用第二套候选序列。
同步信号的SCS可以跟频段关联，比如频段1用15KHz和30KHz的SCS，频段2用120KHz和240Khz的SCS。再比如，所有频段可以使用一个SCS或一个SCS集合。
通过检测候选SCS和候选序列，终端可以检测到某个同步信号，比如在频段1上检测出了SCS为30KHz的某个同步信号。
检测出同步信号后，终端可以接收广播信道，广播信道的SCS可以与上述同步信号的SCS相同或存在某种关联关系。广播信道的时频资源也可以与上述同步信号的时频资源存在某种关联关系，比如在相同或相邻的符号上，或者在相同或相邻的RB上。
804，终端根据检测到的第一公共信号，确定第一公共信号在第一集合中的第一索引和第一公共信号的第二索引。
作为一种实现方法，终端在检测到第一公共信号后，还可以根据第一公共信号确定第一集合。比如，基站向终端发送的集合可以有多种，比如包括由10个公共信号构成的集合，由8个公共信号构成的集合或由6个公共信号构成的集合。基站可以选择其中一个集合，向终端发送该集合中的公共信号，该集合即为第一集合。终端在检测到第一公共信号之后，可以根据第一公共信号，确定第一公共信号所属的第一集合是上述多个集合中的哪一个集合。比如，终端可以根据第一公共信号的同步信号的序列确定第一集合，或者终端可以根据第一公共信号对应的第一信道确定第一集合。在本申请中，该第一信道可以为广播信道、承载系统信息的信道或控制信道，该控制信道用于调度该承载系统信息的信道。
作为另一种实现方法，也可以是协议预定义基站向终端发送的第一集合，也即基站向终端发送的第一集合是预先被终端获知的。因此，终端可以不需要执行上述确定第一集合的操作。
805，终端根据第一索引和第二索引，或根据第二索引，确定第一公共信号的资源。
作为一种实现方法，第一公共信号在第一集合中的第一索引对应多个资源，而第二索引可以指示该多个资源中的一个，因此终端根据第一索引和第二索引，能够确定第一公共信号的资源。以图7为例，该第一公共信号可以是发送的公共信号0至公共信号7中的任一个，在终端检测第一公共信号之后，可以确定第一公共信号在第一集合中的第一索引， 用于指示该第一公共信号是第一集合中的第几个公共信号，以及，还可以确定第一公共信号的第二索引，该第二索引指示了第一公共信息对应的多个资源中的一个。比如，确定检测到的第一公共信号的第一索引是3，该第一索引指示的第一公共信号是公共信号3，则终端根据第一索引可以确定第一公共信号对应由资源4和资源8组成的资源集合，也即基站在发送公共信号3时，为公共信号3分配资源4或资源8。进一步地，终端可以根据第二索引确定基站为公共信号3实际分配的资源，比如第二索引指示资源4，则终端确定公共信号3的资源为资源4，也即基站为公共信号3实际分配资源4。
作为另一种实现方法，终端根据第二索引，从第一集合对应的多个资源中确定第一公共信号的资源。该方案下，终端确定第一公共信号的资源时，不需要使用第一索引。并且，第一公共信号的资源可以是第一公共信号对应的多个资源中的任一个，其中第一公共信号对应的多个资源，也称为第一索引对应的多个资源，或称为第一集合对应的多个资源。比如，第一分组规则将公共信号0至公共信号7分为一个分组，该分组对应的由资源1至资源8组成的资源集合，基站可以为该8个公共信号中的任意一个公共信号分配资源1至资源8中的任意一个资源。因此，基站可以按照任意的发送顺序来发送第一集合中的8个公共信号。终端检测到的第一公共信号可以是发送的公共信号0至公共信号7中的任一个，在终端检测第一公共信号之后，可以确定第一公共信号在第一集合中的第一索引，用于指示该第一公共信号是第一集合中的第几个公共信号，以及，还可以确定第一公共信号的第二索引，该第二索引指示了第一公共信息对应的多个资源(即资源1至资源8)中的一个。比如，终端确定检测到的第一公共信号的第一索引是3，该第一索引指示的第一公共信号是公共信号3，第二索引指示资源1至资源8中的某个资源，比如第二索引指示的是资源1，则可以确定基站为公共信号3分配了资源1。
基于上述方案，终端根据检测到的第一公共信号确定第一公共信号在第一集合中的第一索引和第二索引，进一步确定该第一公共信号的资源。该方法中，一个公共信号可以对应一个或多个资源，且不同资源之间可以是时分复用的，因此一个公共信号有多种发送时机。并且由于每个公共信号对应一个波束发送方向，因而对应某个波束发送方向的公共信号的发送时机是可以灵活调整的。在发送一个集合中的多个公共信号时，可以根据业务需求，确定对应不同波束发送方向的各个公共信号的先后发送顺序，进而确定各个公共信号占用的资源。通过该方法可以实现一个集合中的多个公共信号在不同的波束上的灵活发送，可以提升公共信号被终端检测到的可能性，从而减少资源浪费。
作为一种实现方法，在上述操作805之后，终端还可以根据第一集合和第一公共信号的资源，确定第一集合中除第一公共信号之外的公共信号的资源。例如，第一集合包括8个公共信号，分别为公共信号0至公共信号7，终端检测到的第一公共信号为公共信号3，则终端在确定了公共信号3的资源后，还可以根据第一集合、公共信号3的第一索引以及公共信号3的资源，确定公共信号0至公共信号2，以及公共信号4至公共信号7的资源。
作为一种实现方法，在上述操作805之后，终端还可以根据第一索引或第二索引，确定第二公共信号的资源；以及根据第二公共信号的资源，接收第二公共信号。该第二公共信号的含义可以参考前述描述，不再赘述。比如，第一公共信号的第一索引与第二公共信号的资源之间存在对应关系，因此可以根据第一公共信号的第一索引，以及第一公共信号 的第一索引与第二公共信号的资源之间的对应关系，确定与第一索引对应的第二公共信号的资源。再比如，根据第二索引可以确定第一公共信号对应的多个资源中的一个，然后再根据确定的第一公共信号的资源，确定与第一公共信号的资源对应的第二公共信号的资源。
作为一种实现方法，在上述操作805之后，终端还可以根据第一公共信号进行无线资源管理(radio resource management，RRM)测量，得到第一公共信号对应的RRM测量结果，该RRM测量结果由第一索引进行标识；以及向基站发送第一公共信号对应的RRM测量结果。其中，RRM测量结果包括但不限于：参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)、接收信号强度指示(received signal strength indication，RSSI)或信号与干扰加噪声比(Signal to interference plus noise ratio，SINR)中的至少一个。
本申请实施例中，可以根据以下任一种方法确定第一公共信号在第一集合中的第一索引：
方法1，根据同步信号的序列，确定第一公共信号在第一集合中的第一索引。
比如，同步信号的序列1对应第一索引，同步信号的序列2、同步信号的序列3分别对应其它索引。这里的同步信号的序列可以是PSS的序列，也可以是SSS的序列。
再比如，PSS和SSS的序列组合1对应第一索引，PSS和SSS的序列组合2、PSS和SSS的序列组合3分别对应其它索引。
方法2，根据第一公共信号对应的第一信道，确定第一公共信号在第一集合中的第一索引。
可选的，根据第一信道对应的以下信息中的一个或多个信息，确定第一公共信号在第一集合中的第一索引：用于指示第一索引的信息、第一信道的扰码、第一信道的DMRS序列。
用于指示第一索引的信息对应第一信道的第一字段，比如该第一字段包含3比特，则可以指示八个索引，例如“000”指示第一索引，其它七个比特信息用于指示其它索引。
第一信道的扰码有多种，比如扰码1对应第一索引，扰码2、扰码3等对应其它索引。当终端获取到第一信道的扰码1，则确定第一索引。
第一信道的DMRS序列有多种，比如DMRS序列1对应第一索引，DMRS序列2、DMRS序列3等对应其它索引。当终端获取到第一信道的DMRS序列1，则确定第一索引。
本申请实施例中，可以根据以下任一种方法确定第一公共信号的第二索引：
方法1，根据同步信号的序列，确定第一公共信号的第二索引。
比如，同步信号的序列1对应第二索引，同步信号的序列2、同步信号的序列3分别对应其它索引。这里的同步信号的序列可以是PSS的序列，也可以是SSS的序列。
再比如，PSS和SSS的序列组合1对应第二索引，PSS和SSS的序列组合2、PSS和SSS的序列组合3分别对应其它索引。
方法2，根据第一公共信号对应的第一信道，确定第一公共信号的第二索引。
可选的，根据第一信道对应的以下信息中的一个或多个信息，确定第一公共信号的第二索引：用于指示第二索引的信息、第一信道的扰码、第一信道的DMRS序列。
用于指示第二索引的信息对应第一信道的第二字段，比如该第二字段包含3比特，则可以指示八个索引，例如“000”指示第二索引，其它七个比特信息用于指示其它索引。
第一信道的扰码有多种，比如扰码1对应第二索引，扰码2、扰码3等对应其它索引。当终端获取到第一信道的扰码1，则确定第二索引。
第一信道的DMRS序列有多种，比如DMRS序列1对应第二索引，DMRS序列2、DMRS序列3等对应其它索引。当终端获取到第一信道的DMRS序列1，则确定第二索引。
需要说明的是，上述确定第一索引的方法，与上述确定第二索引的方法，可以相互结合实施。
比如，可以根据同步信号的序列，确定第一公共信号在第一集合中的第一索引，以及确定第一公共信号的第二索引。示例性地，同步信号的序列与第一索引、第二索引的关系如表1所示。
表1
同步信号的序列 第一索引 第二索引
序列1 1 0
序列2 1 1
序列3 2 0
序列4 2 1
序列5 3 0
序列6 3 1
序列7 4 0
序列8 4 1
…… …… ……
例如，当同步信号的序列为序列3，则确定第一索引为2，第二索引为索引0。当同步信号的序列为序列6，则确定第一索引为3，第二索引为索引1。
再比如，还可以根据第一公共信号对应的控制信道，确定第一公共信号在第一集合中的第一索引，以及确定第一公共信号的第二索引。示例性地，以控制信道的扰码为例，控制信道的扰码与第一索引、第二索引的关系如表2所示。
表2
控制信道的扰码 第一索引 第二索引
扰码1 1 0
扰码2 1 1
扰码3 2 0
扰码4 2 1
扰码5 3 0
扰码6 3 1
扰码7 4 0
扰码8 4 1
…… …… ……
例如，当控制信道的扰码为扰码3，则确定第一索引为2，第二索引为索引0。当控制信道的扰码为扰码6，则确定第一索引为3，第二索引为索引1。
再比如，根据同步信号的序列确定第一公共信号在第一集合中的第一索引，以及根据第一公共信号对应的广播信道确定第一公共信号的第二索引。
再比如，根据第一公共信号对应的广播信道确定第一公共信号在第一集合中的第一索引，以及根据第一公共信号对应的控制信道确定第一公共信号的第二索引。
作为一种实现方法，本申请实施例中，在确定第一索引或第二索引时，还使用到了公共信号的分组规则。比如，终端根据第一分组规则，确定第一索引或第二索引。可选的，终端从多个候选规则中确定第一集合对应的第一分组规则。
下面结合示例进行说明。
比如，终端确定的第一分组规则如下：
组1包括公共信号0和公共信号4，组1对应由资源1和资源5组成的资源集合1；
组2包括公共信号1和公共信号5，组2对应由资源2和资源6组成的资源集合2；
组3包括公共信号2和公共信号6，组3对应由资源3和资源7组成的资源集合3；
组4包括公共信号3和公共信号7，组4对应由资源4和资源8组成的资源集合4。
在一个示例中，控制信道的某个字段用于指示第一索引和第二索引。终端获取到控制信道的该字段中的比特信息，由于公共信号一共有8个，因此终端先获取该字段的前3比特信息，根据该3比特信息确定第一索引。然后终端根据第一集合对应的第一分组规则，确定每个分组中有两个公共信号，则终端进一步只需要在该字段中获取1比特信息，比如获取第4比特信息，根据该1比特信息可以确定第二索引。比如，确定的第一索引为3，用于指示公共信号3，第二索引为“0”，用于指示资源4，则终端可以确定检测到的第一公共信号为公共信号3，且对应资源4。再比如，确定的第一索引为5，用于指示公共信号5，第二索引为“1”，用于指示资源6，则终端可以确定检测到的第一公共信号为公共信号5，且对应资源6。
作为一种实现方法，终端可以根据以下任一种或多种方法，从多个候选分组规则中确定第一集合对应的第一分组规则：
方法1，根据第一公共信号中的同步信号的序列，从多个候选分组规则中确定第一集合对应的第一分组规则。
比如，同步信号的序列1对应第一分组规则，同步信号的序列2、同步信号的序列3等对应其它候选分组规则。这里的同步信号的序列可以是PSS的序列，也可以是SSS的序列。
再比如，PSS和SSS的序列组合1对应第一分组规则，PSS和SSS的序列组合2、PSS和SSS的序列组合3等对应其它候选分组规则。
方法2，根据第一集合对应的一个分组内的公共信号的数量，从多个候选分组规则中 确定第一集合对应的第一分组规则。
比如，终端从基站收到一个数量信息，该数量信息指示了第一集合对应的一个分组内的公共信号的数量，则终端可以根据该数量信息以及预定义规则，确定第一集合对应的第一分组规则。
例如，终端收到数量信息为2，即每个分组内包含2个公共信号，则终端确定第一分组规则为：
组1包括公共信号0和公共信号4，组1对应由资源1和资源5组成的资源集合1；
组2包括公共信号1和公共信号5，组2对应由资源2和资源6组成的资源集合2；
组3包括公共信号2和公共信号6，组3对应由资源3和资源7组成的资源集合3；
组4包括公共信号3和公共信号7，组4对应由资源4和资源8组成的资源集合4。
再例如，终端收到数量信息为4，即每个分组内包含4个公共信号，则终端确定第一分组规则为：
组1包括公共信号0至公共信号3，组1对应由资源1至资源4组成的资源集合1；
组2包括公共信号4至公共信号7，组2对应由资源5至资源8组成的资源集合2。
方法3，根据TDD配置，从多个候选分组规则中确定第一集合对应的第一分组规则。
每种TDD配置指示了上行时域资源与下行时域资源之间的比例。这里的时域资源包括符号、时隙、子帧或无线帧中的至少一种。可选的，终端可以从检测到的第一公共信号中获取到当前的TDD配置。
比如，TDD配置1对应第一分组规则，TDD配置2、TDD配置3分别对应其它的候选分组规则。当终端确定当前的TDD配置为TDD配置1，则终端从多个候选分组规则中确定第一集合对应的第一分组规则。
