应理解,在本申请实施例中,所述多次传输所传输的数据包可以完全相同,也可以不完全相同,但都至少包含所述第一数据。例如,终端设备在第一次传输时传输的数据包可以包括第一数据和第三数据,第二次传输时传输的数据包可以包括第一数据和第四数据。
由于不同的MIMO传输模式对传输性能的影响不同,所述终端设备采用不同的传输模式向网络设备多次传输所述第一数据,所述网络设备可以根据所述多次传输的接收情况,在所述多次传输中确定传输质量最优的一次传输,进一步地,所述网络设备可以向终端设备发送第一指示信息,通知所述终端设备传输质量最优的一次传输,从而所述终端设备可以根据传输质量最优的所述一次传输使用的传输参数,确定后续进行数据传输使用的传输参数,从而能够提升上行传输的可靠性。
可选地,作为一个实施例,所述终端设备采用不同的传输方式向所述网络设备多次传输所述第一数据,包括:
所述终端设备采用不同的多输入多输出MIMO传输模式向所述网络设备多次传输所述第一数据。
其中,多输入多输出(Multiple-Input Multiple-Output,MIMO)传输模式具体指传输信号使用的MIMO技术,例如,MIMO传输模式可以包括发送分集,基于码本的预编码,基于非码本的预编码、单天线端口传输和波束赋形等传输模式。
具体而言,所述终端设备可以多次传输所述第一数据可以采用不同的MIMO传输模式。例如,所述多次传输包括两次传输,所述终端设备进行所
述第一数据的两次传输可以分别采用上述MIMO传输模式中的两种传输模式,作为示例而非限定,所述终端设备第一次传输所述第一数据可以采用基于非码本预编码(non-codebook based precoding)的MIMO传输模式,第二次传输所述第一数据可以采用发送分集的MIMO传输模式。
由于采用不同的MIMO传输模式,对所述第一数据的传输性能的影响不同,例如,采用基于非码本预编码的MIMO传输模式可能能够获得更高的预编码增益,但是信道互易性可能是非理想的,因此,可能导致传输失败,而采用发送分集或者单天线端口的MIMO传输模式,可能能够获得更稳定的传输性能,因此,所述终端设备使用不同的MIMO传输模式传输所述第一数据,以便于所述网络设备从多种MIMO传输模式中确定传输质量最优的MIMO传输模式,进一步地,可以通知所述终端设备哪种MIMO传输模式的传输质量最优,从而所述终端设备可以使用该MIMO传输模式进行后续的数据传输,从而提升上行传输的可靠性。
可选地,作为另一个实施例,所述终端设备采用不同的传输方式向所述网络设备多次传输所述第一数据,包括:
所述终端设备采用不同的天线端口向所述网络设备多次传输所述第一数据。
具体而言,所述终端设备可以多次传输所述第一数据可以采用不同的天线端口。例如,多次传输包括两次传输,所述终端设备第一传输所述第一数据可以采用第一天线端口,第二次传输所述第一数据可以采用第二天线端口,其中,所述第一天线端口和所述第二天线端口不同。
需要说明的是,在本申请实施例中,所述第一天线端口可以包括至少一个天线端口,所述第二天线端口也可以包括至少一个天线端口,所述第一天线端口和所述第二天线端口不同可以指所述第一天线端口包括的至少一个天线端口和所述第二天线端口包括的至少一个天线端口部分不同或全部不同。
例如,若终端设备包括N个天线端口,对于所述第一数据的第k次传输,所述终端设备可以通过索引号为n的天线端口进行传输,其中,N为大于1的整数,k为大于或等于1的整数,n=(k-1)mod N,即n为(k-1)对N求模得到的整数。其中,不同的天线端口可以采用不同的波束进行赋形,或者采用不同的预编码矩阵进行预编码,或者不同的天线端口可以映射到不同
的物理天线上。
可选地,作为再一个实施例,所述终端设备采用不同的传输方式向所述网络设备多次传输所述第一数据,包括:
所述终端设备采用不同的预编码矩阵向所述网络设备多次传输所述第一数据。
也就是说,所述终端设备可以多次传输所述第一数据可以采用不同的预编码矩阵。在一种可能的实现方式中,所述终端设备可以通过轮询的方式从预配置的预编码矩阵集合中获取每次传输所述第一数据使用的预编码矩阵。例如,所述终端设备可以预存储一个包含N个预编码矩阵的预编码矩阵集合,对于所述第一数据的第k次传输,终端设备可以利用所述预编码矩阵集合中的索引为m的预编码矩阵对所述第一数据进行预编码,其中,N为大于1的整数,k为大于或等于1的整数,m=(k-1)mod N。
可选地,作为再一个实施例,所述终端设备采用不同的传输方式向所述网络设备多次传输所述第一数据,包括:
所述终端设备采用不同的天线阵列块向所述网络设备多次传输所述第一数据。
也就是说,所述终端设备可以多次传输所述第一数据可以采用不同的天线阵列块,在一种可能的实施例中,所述终端设备可以通过轮询的方式从多个天线阵列块中获取每次传输所述第一数据使用的天线阵列块。例如,若终端设备包括N个天线阵列块,对于所述第一数据的第k次传输,所述终端设备可以通过索引号为p的天线阵列块进行传输,其中,N为大于1的整数,k为大于或等于1的整数,p=(k-1)mod N。
其中,一个天线阵列块也称为一个Panel,一个Panel由一组天线阵子组成,不同的天线阵列块连接独立的射频模块,可以独立的发送信号。
可选地,作为再一个实施例,所述终端设备采用不同的传输方式向所述网络设备多次传输所述第一数据,包括:
所述终端设备采用不同的波束向所述网络设备多次传输所述第一数据。
也就是说,所述终端设备多次传输所述第一数据可以采用不同的波束。例如,所述终端设备第一次传输所述第一数据可以采用第一波束,第二次传输所述第一数据可以采用与第一波束不同的第二波束。
应理解,在本申请实施例中,所述第一波束可以包括至少一个波束,所
述第二波束也可以包括至少一个波束,所述第一波束和第二波束不同可以指所述第一波束包括的至少一个波束和所述第二波束包括的至少一个波束部分不同或全部不同。
在一种可能的实施例中,所述终端设备可以通过轮询的方式从多个波束中确定每次传输所述第一数据所使用的波束。例如,终端设备预先确定了N个波束,其中,N为大于1的整数,所述N个波束可以用于所述终端设备向网络设备传输数据,所述终端设备可以轮换使用所述N个波束中的波束向所述网络设备传输所述第一数据。作为示例而非限定,对于所述第一数据的第k次传输,可以利用所述N个波束中的索引为q的波束传输所述第一数据,其中,q=(k-1)mod N。其中,所述N个波束可以由网络设备指示给终端设备,即所述网络设备可以给所述终端设备配置所述N个波束,例如,所述网络设备可以通过半静态信令(例如,无线资源控制(Radio Resource Control,RRC)信令)或动态信令(例如,DCI)给所述终端设备配置所述N个波束。
可选地,作为再一个实施例,所述终端设备采用不同的传输方式向所述网络设备多次传输所述第一数据,包括:
所述终端设备采用不同的发送功率向所述网络设备多次传输所述第一数据。
具体而言,所述终端设备多次传输所述第一数据可以采用不同的发送功率。例如,所述终端设备第一次传输所述第一数据时可以采用较低的发送功率以节约功率,第二次传输所述第一数据时,所述终端设备可以采用相对较高的发送功率,以提高传输成功的概率,也就是说,第k+1次传输可以采用比第k次传输更高的发送功率,直到达到最高的发送功率。
可选地,在本申请实施例中,所述终端设备对第一数据的第k+1次传输相对于第k次传输提高的发送功率的大小(可以称为功率增加值,或功率步进值)可以由网络设备预配置给所述终端设备,或者所述终端设备也可以采用固定的功率增加值或者功率步进值。
可选地,作为再一个实施例,所述终端设备采用不同的传输方式向所述网络设备多次传输所述第一数据,包括:
所述终端设备采用不同的解调参考信号DMRS序列向所述网络设备多次传输所述第一数据。
其中,解调参考信号(DeModulation Reference Signal,DMRS)序列用
于上行控制和数据信道的相关解调,因此,不同的DMRS序列能够影响上行的解调性能。
可选地,在一些实施例中,所述不同的传输方式包括第一传输方式,所述终端设备采用不同的传输方式向所述网络设备多次传输所述第一数据,包括:
所述终端设备根据第一传输方式以及第一对应关系,确定所述第一传输方式对应的第一资源池,所述第一对应关系是多个传输方式和多个资源池的对应关系,每个传输方式对应的资源池不同;
在所述第一资源池中,使用所述第一传输方式向所述网络设备传输所述第一数据。
也就是说,所述终端设备多次传输所述第一数据可以在不同的资源池中传输。可选地,所述终端设备传输所述第一数据采用的多种传输方式可以和多个资源池具有对应关系,所述终端设备可以根据传输所述第一数据采用的传输方式,以及所述对应关系,确定传输所述第一数据使用的资源池,从而在采用所述传输方式传输所述第一数据时,所述终端设备可以在所述资源池中进行。例如,所述终端设备可以在采用第一传输方式传输第一数据时,可以根据所述第一传输方式以及多种传输方式和多个资源池的对应关系,确定所述第一传输方式对应的第一资源池,从而在使用所述第一传输方式传输所述第一数据时,可以在所述第一资源池中传输所述第一数据。
可选地,在本申请实施例中,所述对应关系可以为多种MIMO传输模式和多个资源池的对应关系,也可以为多个天线端口和多个资源池的对应关系,或者也可以为多个发送功率和多个资源池的对应关系等。
