具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创 造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
应理解，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，简称为“GSM”)系统、码分多址(Code Division Multiple Access，简称为“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access，简称为“WCDMA”)系统、通用分组无线业务(General Packet Radio Service，简称为“GPRS”)、长期演进(Long Term Evolution，简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex，简称为“FDD”)系统、LTE时分双工(Time Division Duplex，简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System，简称为“UMTS”)、全球互联微波接入(Worldwide Interoperability for Microwave Access，简称为“WiMAX”)通信系统或未来的5G系统等。
特别地，本发明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，简称为“SCMA”)系统、低密度签名(Low Density Signature，简称为“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，本发明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，简称为“OFDM”)、滤波器组多载波(Filter Bank Multi-Carrier，简称为“FBMC”)、通用频分复用(Generalized Frequency Division Multiplexing，简称为“GFDM”)、滤波正交频分复用(Filtered-OFDM，简称为“F-OFDM”)系统等。
本发明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，本发明实施例并不限定。
本发明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，本发明实施例并不限定。
图1是本发明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。
与LTE系统中的单波束传输机制不同，在未来通信系统中，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，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。如图2所示，数据信号在经过数字波束赋形后，形成每个射频单元的数字发送信号，通过数模转换器变成模拟信号。每个射频单元对应的模拟信号经过不同的相移器，形成模拟赋形信号在不同的天线单元上传输，从而实现在模拟域进行波束赋形。通过这种混合波束赋形的方法可以降低射频通道的数量，从而降低硬件成本，同时还能获得赋形增益。
图3示出了根据本发明实施例的传输信号的方法100的示意性框图。如图3所示，该方法100包括：
S110，终端设备根据检测到的同步信号和/或同步信道，确定传输信号所采用的波束数量或确定所述信号的传输个数N，N为正整数；
S120，所述终端设备根据所述波束数量或所述传输个数N，与网络设备进行所述信号的传输。
首先，需要说明以下几点：
一、这里的信号可以是上行信号，也可以是下行信号。可以是该信号包 括以下信号中的至少一种信号：广播信号、随机接入信号、参考信号、控制信号和波束参考信号。
二、这里的波束数量和传输个数N是一一对应的。具体地，经过N个波束可以获得N个波束赋形的信号。
三、这里的与网络设备进行该信号的传输，是指跟网络设备进行该信号的收发。可以是终端设备接收网络设备发送的该信号，也可以是终端设备向网络设备发送该信号。
随着通信技术的不断演进，未来通信系统中需要多样化的业务种类，多波束传输机制应运而生。灵活配置传输信号采用的波束数量或信号的传输个数，能够提高小区接入的质量，并且由于既支持单波束传输机制又支持多波束传输机制，从而在检测复杂度和波束赋形增益之间有很好的折中。
应理解，信号的传输个数可以使用资源数量表示。例如，信道状态信息-参考信号(Channel State Information-Reference Signal，CSI-RS)资源数量。
可选地，在本发明实施例中，该同步信号携带序列信息，该终端设备根据检测到的同步信号，确定传输信号所采用的波束数量或确定该信号的传输个数N，包括：该终端设备根据该序列信息，确定与该序列信息对应的该波束数量或该传输个数N。
可选地，序列信息可以是生成序列所用的序列标识。该序列信息可以由主同步信号得到，也可以由辅同步信号得到，也可以由主同步信号和辅同步信号联合得到。具体地，终端设备可以预先存储序列信息与波束数量或者传输个数的对应关系，再根据序列信息确定波束数量或传输个数。例如，序列标识为0-503的范围内对应波束数量或传输个数为1即单波束传输，序列标识为504-1007的范围内对应波束数量或传输个数为N，即多波束传输，其中N为预先约定的大于1的正整数。或者，还可以是序列标识为0～100的范围对应波束数量或传输个数为1，序列标识为101～200的范围对应波束数量或传输个数为2，序列标识为201～300的范围对应波束数量或传输个数为3等。
可选地，在本发明实施例中，该同步信号包括主同步信号和辅同步信号，该终端设备根据检测到的同步信号，确定传输信号所采用的波束数量或确定该信号的传输个数N，包括：该终端设备根据该主同步信号和该辅同步信号之间相差的第一时域资源单元数量，确定与该第一时域资源单元数量对应的 该波束数量或该传输个数N；或该终端设备根据该主同步信号和该辅同步信号之间相差的第一频域资源单元数量，确定与该第一频域资源单元数量对应的该波束数量或该传输个数N。
具体地，第一时域资源单元数量可以是主同步信号和辅同步信号之间相差的传输时间单元数量。这里传输时间单元可以是子帧、OFDM符号、时隙、缩短时隙、缩短子帧等。第一频域资源单元数量可以是物理资源块(Physical Resource Block，PRB)、子载波等。终端设备可以预先存储该第一频域资源单元数量与波束数量或者传输个数的对应关系。终端设备也可以预先存储该第一时域资源单元数量与波束数量或传输个数的对应关系。举例来说，如果主同步信号和辅同步信号之间相差A个OFDM符号，则波束数量或传输数量为1即单波束传输；如果主同步信号和辅同步信号之间相差B个OFDM符号，则波束数量或传输数量为N，即多波束传输，其中N为预先约定的值。
可选地，在本发明实施例中，该同步信道携带用于指示该波束数量或该传输个数N的指示信息，该终端设备根据检测到的同步信道，确定传输信号所采用的波束数量或确定该信号的传输个数N，包括：该终端设备根据该指示信息，确定该波束数量或该传输个数N。该指示信息与波束数量或传输个数之间的对应关系可以由网络设备和终端设备之间预先约定好，也可以由网络设备配置，通过信令指示给终端设备。该指示信息还可以用于指示当前波束的波束标识。举例来说，该指示信息可以为1bit，可以约定若该指示信息为0则可以确定为单波束，若该指示信息为1可以确定为多波束N，N为预先约定好大于1的正整数。再例如，该指示信息为2bit，可以约定00对应波束数量为1，01对应波束数量为2，10对应波束数量为3，11对应波束数量为4。
可选地，在本发明实施例中，该终端设备根据检测到的同步信道，确定传输信号所采用的波束数量或确定该信号的传输个数N，包括：述终端设备根据该检测到的同步信道所用的加扰序列，确定与该加扰序列对应的该波束数量或该传输个数N。具体的，终端设备可以预先存储序列标识与波束数量或者传输个数的对应关系，再根据加扰序列生成所用的序列标识确定波束数量或传输个数。例如，序列标识小于A时对应波束数量或者传输个数为K1，序列标识大于等于A小于B时对应波束数量或者传输个数为K2，序列标识大于等于B时对应波束数量或者传输数量个数为K3。
可选地，在本发明实施例中，该终端设备根据检测到的同步信号和同步信道，确定传输信号所采用的波束数量或确定该信号的传输个数N，包括：该终端设备根据该同步信号和该同步信道之间相差的第二时域资源单元数量，确定与该第二时域资源单元数量对应的该波束数量或该传输个数N；该终端设备根据该同步信号和该同步信道之间相差的第二频域资源单元数量，确定与该第二频域资源单元数量对应的该波束数量或该传输个数N。
具体地，第二时域资源单元数量可以是同步信号和同步信道之间相差的传输时间单元数量。这里传输时间单元可以是子帧、OFDM符号、时隙、缩短时隙、缩短子帧等。第二频域资源单元数量可以是物理资源块(Physical Resource Block，PRB)、子载波等。终端设备可以预先存储该第一频域资源单元数量与波束数量或者传输个数的对应关系。终端设备也可以预先存储该第一时域资源单元数量与波束数量或传输个数的对应关系。举例来说，如果主同步信号和辅同步信号之间相差A个OFDM符号，则波束数量或传输数量为1即单波束传输；如果主同步信号和辅同步信号之间相差B个OFDM符号，则波束数量或传输数量为N，即多波束传输，其中N为预先约定的值。
可选地，在本发明实施例中，该终端设备根据检测到的同步信号或同步信道，确定传输信号所采用的波束数量或确定该信号的传输个数N，包括：该终端设备根据该同步信号的物理资源，确定与该物理信号的物理资源对应的该波束数量或该传输个数N；或该终端设备根据该同步信道的物理资源，确定与该同步信道的物理资源对应的该波束数量或该传输个数N。
可选地，同步信号的物理资源与波束数量或传输个数之间的对应关系可以由网络设备和终端设备之间预先约定好，也可以由网络设备配置，通过信令指示给终端设备。
可选地，同步信道的物理资源与波束数量或传输个数之间的对应关系可以由网络设备和终端设备之间预先约定好，也可以由网络设备配置，通过信令指示给终端设备。
可选地，在本发明实施例中，该终端设备根据检测到的同步信号和/或同步信道，确定传输信号所采用的波束数量或确定该信号的传输个数N，包括：该终端设备根据该同步信号或该同步信道，确定传输该信号采用的是1个波束或M个波束，或确定该信号的传输个数为1个或K个，M和K分别为预存的大于1的正整数。
作为一个特殊的实施例，该波束数量或传输个数也可以为0，此时终端不需要接收信号。本领域技术人员理解，有些信号只能在多波束机制下传输，若传输这些信号的波束为1，那么终端设备可以不进行这些信号的收发，例如，如果所述信号为波束参考信号，波束数量为1，则不需要接收所述波束参考信号。再例如，如果所述信号为波束参考信号，且传输个数为0，则可以不需要接收所述波束参考信号。应理解，本发明仅以波束参考信号为例进行说明，本发明并不限于此。
还应理解，上述各种对应关系可以由网络设备指示给终端设备，也可以是由网络设备和终端设备预先约定好。且上述仅以同步信号和/或同步信道的一些相关特性为例进行说明，本发明并不限于此。
作为一个具体的实施例，终端设备检测同步信号，从同步信号中盲检得到同步序列标识，该同步序列标识由主同步信号携带的标识1和辅同步信号携带的标识2得到。终端根据所述同步序列标识，确定PBCH传输所采用的波束数量N。其中，同步序列标识和波束数量的对应关于由终端设备与网络设备预先约定好。一部分同步序列标识对应单个波束，另一部分同步序列标识对应多个波束，多个波束情况下波束数量固定为K，即波束数量N为1或者K。终端可以根据所述波束数量N进行PBCH的接收。其中，终端需要分别接收N个PBCH信号，这些PBCH信号由网络设备采用N个波束进行赋形后发送给终端设备，所述N个PBCH信号采用不同的物理资源传输。所述PBCH信号的物理资源为与检测到同步信号的物理资源有固定映射关系的N个物理资源。
作为另一个具体的实施例，终端设备检测同步信号；终端设备检测同步信号对应的PBCH，根据所述PBCH携带的信号传输个数指示信息得到信号的传输个数。终端设备根据所述信号传输个数N进行后续N个波束参考信号的接收。其中，终端需要接收N个波束参考信号，每个波束参考信号由网络设备采用不同的波束进行赋形后发送给终端设备，所述N个波束参考信号采用不同的物理资源传输。所述N个波束参考信号采用的物理资源为终端设备与网络设备预先约定好的N个物理资源。
可选地，在本发明实施例中，同步信道是与同步信号关联的信道：二者的物理资源具有固定的相对位置，和/或同步信道的加扰序列采用同步信号携带的序列标识生成。具体的，同步信号和同步信道所在的传输时间单元可以 具有固定的时间偏移量，或者同步信号和同步信道所在的频域单元可以具有固定的频域偏移量。
应理解，同步信道可以是PBCH(Physical Broadcast Channel)，PSBCH(Physical Sidelink Broadcast Channel)等。上述进行传输的信号可以是如物理广播信道(Physical Broadcast Channel，PBCH)等广播信号、也可也以是物理随机接入信号(Physical Random Access Channel，PRACH)等随机接入信号、还可以是信道状态信息-参考信号(Channel State Information-Reference Signal，CSI-RS)、解调参考信号(Demodulation Reference Signal，DMRS)等参考信号，还可以是控制信号，典型的，所述信号可以是波束参考信号(Beam Reference Signal，BRS)。
可选地，在本发明实施例中，该终端设备根据该波束数量或该传输个数N，与网络设备进行该信号的传输，包括：该终端设备根据该波束数量或该传输个数N，确定与该波束数量或该传输个数N对应的物理资源或序列资源；该终端设备在该物理资源上或采用该序列资源与该网络设备进行该信号的传输。
具体地，终端设备和网络设备之间可以提前约定好每个波束对应信号所用的物理资源，终端设备和/或网络设备根据波束数量或传输个数N确定要发送给的波束对应信号，并且在各个波束对应信号所用的物理资源上进行相应信号的收发。举例来说，终端设备和网络设备可以提前约定好波束数量或传输个数N为4所对应的物理资源为1～4(假设将所有的物理资源划分为20个，并且不同标号的物理资源对应的位置唯一)，那么当终端设备需要传输随机接入信号时，即可根据波束数量或传输个数N确定物理资源1～4进行该随机接入信号的传输。其中，每个物理资源可以包含多个时域资源单元和多个频域资源单元。终端设备和网络设备还可以提前约定好每个波束对应信号所用的序列资源，其中，序列资源可以是用于确定传输该信号所采用的序列。应理解，上述仅仅是本发明实施例的一种示意，本发明实施例并不限于此。
可选地，在本发明实施例中，该终端设备根据该波束数量，与网络设备进行该信号的传输，包括：该终端设备根据该波束数量，向该网络设备发送经过该波束数量对应的波束赋形之后的该信号；或该终端设备接收该网络设备发送的经过该波束数量对应的波束赋形之后的该信号。
可选地，在本发明的另一实施例中，该终端设备根据该传输个数N，与 网络设备进行该信号的传输，包括：述终端设备根据该传输个数N，向该网络设备发送N个该信号；或该终端设备接收该网络设备根据该传输个数N发送的N个该信号。
应理解，传输通常包括收发，换句话说，在本发明实施例中的传输包括终端设备发送信号，和终端设备接收信号。并且终端设备是根据所确定的波束数量或传输个数N向网络设备发送经过波束赋形之后的信号，或终端设备接收网络设备根据所确定的波束数量或传输个数N发送的经过波束赋形之后的信号。
可选地，该N个该信号采用不同的波束进行赋形，其中，N为大于1的正整数。具体是指该信号可以采用不同的波束赋形，也可以是指采用不同的波束进行发送赋形。
进一步地，在本发明实施例中，在该终端设备根据该波束数量或该传输个数N，与网络设备进行该信号的传输之后，该方法还包括：该终端设备根据该波束数量或该传输个数N，接收该网络设备发送的反馈信息，或该终端设备根据该波束数量或该传输个数N，向该网络设备发送反馈信息，其中，该反馈信息用于指示该波束数量对应的波束集合中的第一波束，或该传输个数N对应的信号集合中的第一信号。
本领域技术人员理解，波束赋形技术可以根据信道信息的反馈方式分为基于码本的(Codebook based)和基于信道互易性两种方式。前者基于终端反馈的码本信息，由网络设备确定下一次传输采用的预编码码本；后者则根据上行发送的探测参考信号(Sounding Reference Signal，SRS)，利用信道互易性得到下行信道信息，并进行下行需要的预编码矩阵计算与选择。举例来说，如果网络设备采用N个波束进行赋形，则终端设备通常会根据波束数量上报一个波束索引或者该波束索引对应的CSI-RS资源的索引等，以用于网络设备进行对后续数据进行波束赋形。通常，终端设备上报的波束索引可以是网络设备采用多波束发送的下行信号中信号质量最好的信号所采用的波束，也可以是信号质量排第二的，或其他的波束索引，本发明对此并不构成限定。
可选地，该反馈信息包括该第一波束的波束标识和/或与该波束标识对应的信道状态信息CSI，或该反馈信息包括该第一信号的信号标识和/或与该信号标识对应的信道状态信息CSI。
终端设备根据所述波束数量可以进行波束标识(例如波束索引)的反馈。每个波束标识指示了一个波束在波束数量对应的所有波束中的标识，例如，假设波束数量为N，则一个波束标识的比特数可以为log2(N)。所述终端可以根据波束数量接收各波束对应的信号，从而上报波束标识。终端设备还可以同时进行波束标识对应的CSI的反馈。具体的，终端设备除了反馈用于指示某个波束的信息外，还需要反馈基于该波束测量得到的CSI。例如，该CSI包括秩指示RI、预编码矩阵指示PMI和信道质量指示CQI中的至少一种。
终端设备根据所述信号数量进行信号标识的反馈。每个所述信号标识指示了一个信号在信号数量对应的所有信号中的标识，例如，假设信号数量为N，则一个信号标识的比特数可以为log2(N)。这里的信号可以通过信号所用资源的方式表示，所以信号标识也可以是信号资源标识，比如CSI-RS资源标识。例如，终端设备确定CSI-RS资源的数量为4个，则分别对4个CSI-RS资源上的CSI-RS信号进行检测，得到检测的信号中信号质量最好的CSI-RS信号，将所述CSI-RS信号对应的CSI-RS资源的索引作为信号标识反馈给网络设备。终端设备还可以同时进行信号标识对应的CSI的反馈。具体的，终端设备除了反馈资源标识外，还需要反馈基于资源标识所对应的信号进行测量得到的CSI。例如，该CSI可以是秩指示(Rank Indication，RI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)、信道质量指示(Channel Quality Indicator，CQI)等中的至少一种。
因此，本发明实施例提供的传输信号的方法，能够灵活配置传输信号所采用的波束数量或信号的传输个数，从而提高小区接入的质量，并且由于既支持单波束传输机制又支持多波束传输机制，从而在检测复杂度和波束赋形增益之间有很好的折中。同时，解决了现有技术没有机制在小区接入过程中能够令网络设备或者终端设备确定后续传输所用的波束，终端无法在小区接入后马上获得波束赋形增益的问题。
