Abstract

本发明公开了一种数据传输方法、终端设备、网络设备及计算机存储介质,包括:终端设备确定第一信道使用的传输波形;所述终端设备根据所述传输波形在第一信道进行数据传输。

Description

数据传输方法、终端设备、网络设备及计算机存储介质 技术领域
本发明涉及信息处理技术领域,尤其涉及一种数据传输方法、终端设备、网络设备及计算机存储介质。
背景技术
车联网系统是基于长期演进终端到终端(LTE-D2D,Long Term Evaluation-Device to Device)的一种侧行链路传输技术(SL:Sidelink,侧行链路)。在第三代合作伙伴项目(3GPP,the 3rd Generation Partnership Project)Rel-14中对车联网技术(V2X)进行了标准化,定义了两种传输模式:模式3和模式4;其中,模式3:如图1所示,车载终端的传输资源是由基站分配的,车载终端根据基站分配的资源在侧行链路上进行数据的发送。模式4:如图2所示,车载终端采用侦听(sensing)+预留(reservation)的传输方式,车载终端在资源池中通过侦听的方式获取可用的传输资源集合,终端从该集合中随机选取一个资源进行数据的传输。
在NR-V2X中,需要支持自动驾驶,因此对车辆之间数据交互提出了更高的要求,在5G NR系统中,上行支持两种传输波形:循环前缀OFDM(CP-OFDM,Cyclic Prefix OFDM)和离散傅里叶变换OFDM(DFT-OFDM,Discrete Fourier Transform OFDM)。Rel-14V2X沿用了LTE的上行传输波形,采用DFT-OFDM,在NR-V2X中,为了更加灵活的资源配置,因此可以采用类似5G NR上行的两种传输波形结构,即CP-OFDM和DFT-OFDM。但是,在V2X系统中,如果采用上述的两种传输波形,发送数据时如何选取传输波形以及接收端按照哪种传输波形进行数据的接收是需要解决的问题。

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。
实施例一、
本发明实施例提供了一种数据传输方法,如图3所示,包括:
步骤101:终端设备确定第一信道使用的传输波形;
步骤102:所述终端设备根据所述传输波形在第一信道进行数据传输。
关于前述步骤101,终端设备确定第一信道使用的传输波形,可以为终端设备根据网络设备发送的配置信息、所述第一信道所使用的资源池、所述第一信道所使用的载波中的至少一项,确定所述第一信道使用的传输波形。
具体来说,包括以下多种处理场景:
场景1、
若所述配置信息指示第一传输波形,所述终端设备在多个传输波形中确定所述第一传输波形为所述第一信道使用的传输波形。
其中,所述多个传输波形是预配置在所述终端设备上的,或者由所述网络设备配置的。
所述多个传输波形为两个或更多的传输波形。
终端设备上预配置的多个传输波形可以预先与信道之间并没有关系,即终端设备可以从多个传输波形中任意选取一个传输波形作为第一信道的传输波形。
场景2、所述终端设备根据所述第一信道所使用的资源池以及第一对应关系,确定所述第一信道使用的传输波形,其中,所述第一对应关系为多个资源池和多个传输波形 的对应关系。所述第一对应关系是预配置在所述终端设备上的,或者由所述网络设备配置的。
需要理解的是,本场景中不同的资源池采用的传输波形,可以通过网络配置或者预配置的方式定义资源池对应的传输波形形式;
具体的,在V2X中,可以通过网络配置或者预配置的方式配置多个资源池,不同的资源池可以对应不同的传输波形,资源池和传输波形之间的对应关系可以通过网络配置或者预配置的方式确定。
在网络侧进行配置时,网络侧可以通过RRC信令的方式配置各个资源池的传输波形。
场景3、所述终端设备根据所述第一信道所使用的载波以及第二对应关系,确定所述第一信道使用的传输波形,其中,所述第二对应关系为多个载波和多个传输波形的对应关系;所述第二对应关系是预配置在所述终端设备上的,或者由所述网络设备配置的。
具体的,不同的载波采用不同的传输波形,可以通过网络配置或者预配置的方式定义载波对应的传输波形形式;
在V2X中可以支持多个载波,例如在Rel-15的V2X中可以支持8个载波,可以对不同的载波配置不同的传输波形;例如考虑到后向兼容Rel-14或者Rel-15的终端,在有Rel-14或者Rel-15终端的载波上采用DFT-OFDM传输波形;在其他载波上可以采用DFT-OFDM或者CP-OFDM;具体哪个载波采用哪种传输波形可以通过预配置或者网络配置的方式确定;
另外一个场景就是,V2X既可以工作在专有载波上,也可以工作在上行载波上,因此可以在上行载波上采用和上行数据相同的传输波形,在专有载波上采用相同或者不同的传输波形。
还需要指出的是,前述几种场景中,所述第一信道为物理侧行共享信道PSSCH,或者,所述第一信道为物理侧行控制信道PSCCH。
场景4、
本实施例提供另外一种确定信道传输传输波形的方法,所述第一信道为物理侧行共享信道PSSCH,所述第一信道对应的物理侧行控制信道PSCCH为第二信道。
所述终端设备确定第一信道使用的传输波形,包括:所述终端设备根据所述第二信道,确定所述第一信道使用的传输波形。
所述第二信道中承载指示信息,所述指示信息用于指示第二传输波形。
通过控制信道PSCCH指示数据信道PSSCH采用的传输波形;
PSCCH采用哪种传输波形可以是预定配置的,或者是网络配置的,或者是根据上述场景1到场景3所述的方法确定,在PSCCH中携带指示PSSCH传输波形的信息,可以通过如下的方式实现对PSSCH传输波形的指示:
方式一、PSCCH中通过显示信息指示:所述终端设备根据所述第二信道,确定所述第一信道使用的传输波形,包括:所述终端设备确定所述指示信息指示的所述第二传输波形为所述第一信道使用的传输波形。例如在PSCCH承载的SCI(侧行链路控制信息,Sidelink Control Information)中包含1比特信息,用来指示PSSCH的传输波形,比如,下表所示:
SCI中的指示信息 PSSCH使用的传输波形
0 CP-OFDM
1 DFT-OFDM
需要理解的是,上表所示仅为一种示例,实际上0表示DFT-OFDM、1表示CP-OFDM也是可以的,只是本实施例中不再进行穷举。
还需要理解的是,上表给出了用1比特指示两种传输波形的示例,本实施例适用于使用k比特指示2 k个传输波形。
方式二、通过PSCCH解调参考信号(DMRS,Demodulation Reference Signal)指示:所述终端设备根据所述第二信道对应的DMRS的序列、循环移位、正交覆盖码OCC、资源位置、根序列中的至少一项以及第三对应关系,确定所述第一信道使用的传输波形,其中所述第三对应关系为DMRS的序列、循环移位、正交覆盖码OCC、资源位置、根序列中的至少一项和传输波形之间的对应关系。
其中,所述第三对应关系是预配置在所述终端设备上的,或者由所述网络设备配置的。
具体来说,可以通过DMRS的序列、循环移位、OCC(Orthogonal Cover Code正交覆盖码)、资源位置、跟序列(Root sequence)等指示不同的传输波形,终端通过检测PSCCH的DMRS,获取DMRS的序列、循环移位、OCC、资源位置、跟序列等信息中的至少一项,并且根据第三对应关系,确定所述PSCCH对应的PSSCH采用的传输波形。
方式三、通过PSCCH的扰码信息指示:所述终端设备根据所述第二信道的扰码信息以及第四对应关系,确定所述第一信道使用的传输波形,其中,所述第四对应关系为多个扰码信息与多个传输波形之间的对应关系。所述第四对应关系是预配置在所述终端设备上的,或者由所述网络设备配置的。
也就是,PSCCH上承载SCI信息,所述SCI的信息比特需要经过加扰处理,可以通过不同的扰码序列来隐式的指示PSSCH所使用的传输波形,其中不同的扰码信息或者扰码序列与传输波形之间的对应关系为第四对应关系。
终端通过检测PSCCH上承载的SCI,获取SCI采用的掩码信息,并且根据第四对应关系,确定所述PSCCH对应的PSSCH采用的传输波形。
方式四、所述终端设备根据所述第二信道的掩码信息以及第五对应关系,确定所述第一信道使用的传输波形,其中,所述第五对应关系为多个掩码信息与多个传输波形之间的对应关系。
其中,所述第五对应关系是预配置在所述终端设备上的,或者由所述网络设备配置的。
也就是,PSCCH上承载SCI信息,所述SCI的信息比特需要经过加掩码处理,可以通过不同的掩码序列来隐式的指示PSSCH所使用的传输波形,其中不同的掩码信息或者掩码序列与传输波形之间的对应关系为第五对应关系。
终端通过检测PSCCH上承载的SCI,获取SCI采用的掩码信息,并且根据第四对应关系,确定所述PSCCH对应的PSSCH采用的传输波形。
可见,通过采用上述方案,就能够在终端设备通过信道进行数据传输的时候,预先确定信道所对应的传输波形,再基于选取的传输波形进行信道的传输。如此,就解决了发射端如何选取传输波形以及接收端如何获知发送端采用哪种传输波形进行数据传输的问题,从而使得终端的交互效率有所保证。
