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”)通信系统或未来的第五代(5th Generation，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。
本发明实施例中的第一设备可以是网络侧设备，也可以是终端设备；第二设备可以是网络侧设备，也可以是终端设备，本发明对此不够成限定。
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。
在5G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，以达到5G对传输速率的要求。在高频段进行数据传输时，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。不仅在发送端，在接收端也可以采用类似的方法通过模拟接收赋形来降低接收通道数量。
一般情况下，波束越宽，需要的波束越少；反之，则需要的波束越多。而波束的宽度则与采用的子载波间隔和工作频段等因素有关，例如，工作频段越高则相应波束宽度越窄，故需要的波束也越多。
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，第一设备根据传输信号所采用的基础参数集和/或工作频段，确定传输该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，该第一设备根据该波束数量或该传输个数N，与第二设备进行该信号的传输。
首先，需要说明以下几点：
一、这里的第一设备和第二设备可以分别是终端设备和网络设备，也可以分别是终端设备和终端设备，为了描述方面，下面以在终端设备和网络设备之间传输信号为例进行说明。
二、这里的信号可以是上行信号，也可以是下行信号。可以是同步信号、可以是如物理广播信道(Physical Broadcast Channel，PBCH)、系统信息块(System Information Block，SIB)等广播信号、也可也以是随机接入信号、还可以是CSI-RS、解调参考信号(Demodulation Reference Signal，DMRS)等下行参考信号。
三、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。
四、这里的与第二设备进行该信号的传输，是指跟第二设备进行该信号的收发。可以是第一设备接收第二设备发送的该信号，也可以是第一设备向第二设备发送该信号。
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，LTE系统中采用单一的子载波宽度已经无法满足通信需求。与LTE系统不同，为 了保持系统灵活性和前向兼容性，5G等未来无线通信系统中一个载波/小区/无线传输节点(Transmit Receive point，TRP)中可以有多种基础参数集(numerology)或工作频段。例如，不同的numerology通常采用不同的载波间隔，因此，不同的基础参数集或不同的工作频段对应不同的波束宽度，在5G等未来无限通信系统中，则需要一种新的传输信号的方法，能够支持在不同波束宽度下使用不同数量的波束进行波束赋形，从而在信号开销和赋形增益之间进行很好的折中。
可选地，在本发明实施例中，在该第一设备根据传输信号所采用的基础参数集和/或该工作频段，确定传输该信号所采用的波束数量或确定该信号的传输个数N之前，该方法还包括：该第一设备从至少一个基础参数集中确定该基础参数集，或从至少一个工作频段中确定该工作频段。
具体地，该第一设备从至少一个基础参数集中确定该基础参数集，包括：该第一设备根据该第二设备发送的指示信息，确定该基础参数集，该指示信息用于指示该至少一个基础参数集中的一个基础参数集；或该第一设备根据传输数据的业务类型或工作频点，从该至少一个基础参数集中确定该基础参数集；或该第一设备通过盲检该至少一个基础参数集，确定该基础参数集。
应理解，上述基础参数集可以是由第一设备根据自身传输参数(比如说当前信号的业务类型或工作频点)确定的，也可以是从配置在第一设备的至少一个基础参数集中选出来的，还可以是由第一设备和第二设备预先约定好的，还可以是第二设备将从配置在第二设备的至少一个基础参数集中选出来的基础参数集并告知第一设备等，上述基础参数集也可以是由第一设备通过盲检至少一个基础参数集获得，本发明对第一设备获取基础参数集的方式不作限定。举例来说，终端设备可以从一个预定义的子载波间隔集合中，分别盲检其中的每个子载波间隔，直到检测出采用某个子载波间隔传输的信号。又例如，终端设备和网络设备可以预先约定不同的工作频点对应的基础参数集，终端设备可以根据当前传输数据的工作频点确定对应的基础参数集。
还应理解，上述工作频段即当前传输信号所用的频带或频点范围或某个频点，比如可以是0～6GHz，6～28GHz，28～40GHz，40～60GHz及60GHz以上等。
可选地，上述基础参数集可以包括至少一个参数，具体包括以下参数中的至少一种：
子载波间隔、特定带宽下的子载波数目、物理资源块PRB中的子载波数、正交频分复用OFDM符号的长度、用于生成OFDM信号的傅里叶变换例如快速傅里叶变换(Fast Fourier Transform，简称“FFT”)或傅里叶逆变换例如快速逆傅里叶变换(Inverse Fast Fourier Transform，简称“IFFT”)的点数、传输时间间隔TTI中的OFDM符号数、特定时间长度内包含的TTI的个数和信号前缀类型。更具体地，该至少一个参数可以为用于确定传输信号的时频资源的参数。
其中，子载波间隔指相邻子载波的频率间隔，例如15kHz，60kHz等；特定带宽下的子载波数目例如为每个可能的系统带宽对应的子载波数；PRB中包含的子载波数例如典型的可以是12的整数倍；TTI中包含的OFDM符号数例如典型的可以是14的整数倍；一定时间单位内包含的TTI数可以指1ms或者10ms的时间长度内包含的TTI数目；信号前缀长度例如信号的循环前缀的时间长度，或者循环前缀使用常规CP还是使用扩展CP。
可选地，在本发明实施例中，该第一设备根据传输信号所采用的基础参数集和/或该工作频段，确定传输该信号所采用的波束数量或确定所述信号的传输个数N，包括：该第一设备根据该基础参数集以及预设的第一对应关系，确定该波束数量或该传输个数N，该第一对应关系为该基础参数集与该波束数量或该传输个数N的对应关系；或该第一设备根据该工作频段以及预设的第二对应关系，确定该波束数量或该传输个数N，该第二对应关系为该工作频段与该波束数量或该传输个数N的对应关系。
可选地，该第一设备还可以根据所采用的基础参数集和工作频段以及第三对应关系，确定波束数量或传输个数N。该第三对应关系可以是基础参数集、工作频段以及波束数量这三者的对应关系，也可以是基础参数集、工作频段以及信号数量这三者的对应关系。
应理解，上述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。下面以表1～表3中的对应关系为例进行详细说明。
表1
子载波间隔 波束数量或传输个数
15kHz 4
30kHz 8
60kHz 8
120kHz 16
240kHz 32
表2
子帧包含的OFDM符号数 波束数量或传输个数
14 4
28 8
56 16
112 32
224 64
表3
工作频段(GHz) 波束数量或传输个数
0-2.0 8
2.0-6 16
6-28 32
28-70 64
例如，若由终端设备向网络设备传输随机接入信号，且此时终端设备根据自身的传输特性，或者通过盲检多个子载波间隔，能够确定出传输该随机接入信号所采用的子载波间隔是15kHz，终端设备和网络设备可以预先约定好上述表1并存储在终端设备和/或网络设备中，从而终端设备和/或网络设备可以根据表1确定出传输该随机接入信号所采用的波束数量或者传输该随机接入信号所对应的传输个数为4。再例如，若由网络设备向终端设备传输下行参考信号，如CSI-RS，网络设备可以根据自身的传输特性，或者通过盲检多个子载波间隔，确定出传输该CSI-RS所采用的工作频段为6-28GHz，类似地，终端设备和网络设备可以预先约定好上述表3并存储在终端设备和/或网络设备中，从而终端设备和/或网络设备可以根据表3确定出传输该CSI-RS所采用的波束数量或者传输该CSI-RS所对应的传输个数为32。
应理解，信号的传输个数N可以通过信号所用资源的方式表示。例如，该信号可以通过CSI-RS资源表示，此时传输个数N就是CSI-RS资源数量，或者可以从CSI-RS资源数量中获取。
可选地，在本发明实施例中，该第一设备根据该波束数量或该传输个数N，与第二设备进行该信号的传输，包括：该第一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；该第一设备在该物理资源上或采用该序列资源与该第二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。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，该第一设备根据该波束数量，与第二设备进行该信号的传输，包括：该第一设备根据该波束数量，向该第二设备发送经过该波束数量对应的波束赋形之后的该信号；或该第一设备接收该第二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，该第一设备根据该传输个数N，与第二设备进行该信号的传输，包括：该第一设备根据该传输个数N，向该第二设备发送N个该信号；或该第一设备接收该第二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第一设备发送信号，和第一设备接收信号。并且第一设备是根据所确定的波束数量或传输个数N向第二设备发送经过波束赋形之后的信号，或第一设备接收第二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，在该第一设备根据该波束数量或该传输 个数N，与第二设备进行该信号的传输之后，该方法还包括：该第一设备根据该波束数量或该传输个数N，接收该第二设备发送的反馈信息，或该第一设备根据该波束数量或该传输个数N，向该第二设备发送反馈信息，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。
第一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。第一设备还可以同时进行波束标识对应的CSI的反馈。具体的，第一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。
第一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，第一设备确定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第二设备。第一设备还可以同时进行信号标识对应的CSI的反馈。具体的，第一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。
应理解，在本发明实施例中，该第一设备可以为网络设备或终端设备，该第二设备也可以为网络设备或终端设备，并且终端设备和网络设备、终端设备和终端设备、以及网络设备和网络设备之间的交互可以具体参照上述技术方案。
