下面将结合本公开实施例中的附图,对本公开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公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
参见图1,图1是本公开实施例应用的网络结构示意图。如图1所示,包括网络侧设备11和终端侧设备12。其中,网络侧设备11可以是演进型基站(eNB,evolved Node B)或者其他基站。需要说明的是,在本公开实施例中并不限定网络侧设备11的具体类型。网络侧设备11可以与终端侧设备12建立通信,其中,附图中的网络可以表示网络侧设备11可以与终端侧设备12无线建立通信,终端侧设备12可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant,简称PDA)、移动上网装置(Mobile Internet Device,MID)或可穿戴式设备(Wearable Device)等终端侧设备。需要说明的是,在本公开实施例中并不限定终端侧设备12的具体类型。
基于图1所示的网络结构,本公开实施例提供一种数据传输控制方法,如图2所示,包括以下步骤:
步骤201、网络侧设备将码字映射到至少一数据层上。
步骤202、所述网络侧设备将所述数据层映射到至少一准共位置QCL(quasi co-location)分组上,所述QCL分组为:根据各天线端口之间的QCL关系建立的天线端口分组。
步骤203、所述网络侧设备基于所述QCL分组,进行数据传输。
下面的表1示意性地示出了步骤201中如何将码字映射到至少一数据层 上,即用于空间复用的码字到层的映射(Codeword-to-layer mapping for spatial multiplexing)。其中,x为层,d为码字。
表1
下面示例性地说明步骤202中的层到QCL组的映射。实际上是将层映射 到了QCL组中对应的天线端口(或参考信号端口)。
例如,将v个层映射到v个天线端口上的过程可以表示为:
其中上述码字可以为一个,也可以为多个。每一码字可以映射一个数据层,也可以映射多个数据层。具体的映射方式可以根据数据传输的需要进行设置,在此不做进一步的限定。例如可以采用单层传输方案,则一个码字映射到一个数据层,形成1对1的映射关系。当采用发射分集方案时,可以由一个码字映射到两个或者两个以上的数据层。例如,采用频域分集SFBC时,可以将一个码字映射到两个数据层。而采用频域分集SFBC+频率切换发送分集FSTD时,将一个码字映射到四个数据层。
上述数据层与QCL分组的映射关系可以根据实际需要进行设置,例如针对不同的传输方式对应的映射关系不同。例如可以将同一数据层映射到一个QCL分组中,也可以将同一数据层映射到至少两个QCL分组中,还可以对QCL分组中所包含的数据层的数量或者数据层对应的码字数量进行限制。以下对此进行详细说明:
第一种情况:在非空间复用的状态下,当所述数据传输为单层传输时,上述步骤202包括:
所述网络侧设备将所述数据层映射到一个或者多个QCL分组上。
在第一种情况中,可以通过一个或者多个QCL分组对数据层的数据进行传输,具体可以根据实际需要进行设置,在此不做进一步的限定。
第二种情况:在非空间复用的状态下,当所述数据传输为多层分集传输时,上述步骤202,包括:
当采用相干方式传输数据时,所述网络侧设备将所有的所述数据层映射到一个QCL分组中;
当采用非相干方式传输数据时,所述网络侧设备将不同的数据层子集对应的数据层映射到不同的QCL分组上,且相同的数据层子集对应的数据层映射到一个或者多个QCL分组上。
在第二情况中,当采用非相干方式传输数据时,网络侧设备将会对所有 的数据层子集配置QCL分组,将不同的数据层子集映射到不同的QCL分组中,对于相同的数据层子集可以映射到一QCL分组中,也可以映射到多个QCL分组中,具体可以根据实际需要进行设置。例如数据层子集A包括:数组层A1和数据层A2。数据层子集B包括:数据层B1和数据层B2。QCL分组包括QCL分组1、QCL分组2、QCL分组3和QCL分组4。此时可以将数据层子集A中的数据层A1和数据层A2同时映射到QCL分组1中,将数组层B1映射到QCL分组2中,将数据层B2映射到QCL分组3中。应理解,本实施例中,同一数据层也可以映射到多个QCL分组中,例如可以将数据层B2映射到QCL分组3和QCL分组4中。
第三种情况:在闭环空间复用的状态下,上述步骤202,包括:
当采用相干方式传输数据时,所述网络侧设备将所有的所述数据层映射到一个QCL分组中;
当采用非相干方式传输数据时,所述网络侧设备将不同的数据层子集对应的数据层映射到不同的QCL分组上,且同一数据层子集对应的数据层映射到相同的QCL分组上。
在第三情况中,当采用非相干方式传输数据时,网络侧设备将会对所有的数据层子集配置QCL分组,将不同的数据层子集映射到不同的QCL分组中,对于同一数据层子集对应的数据层映射到相同的QCL分组上,具体可以根据实际需要进行设置。例如第一码字映射的数据层包括数组层A1、数据层A2和数据层A3。第二码字映射的数据层包括B包括:数据层B1、数据层B2和数据层B3。其中,数组层A1和数据层A2构成第一数据层子集,数据层A3构成第二数据层子集,数据层B1和数据层B2构成第三数据层子集,数据层B3构成第三数据层子集。QCL分组包括QCL分组1、QCL分组2、QCL分组3和QCL分组4。此时可以将数据层子集A中的数据层A1和数据层A2同时映射到QCL分组1中,将数据层A3映射到QCL分组2中,将数组层B1和数据层B2映射到QCL分组3中,将数据层B3映射到QCL分组4中。
第四种情况:在开环空间复用的状态下,上述步骤202,包括:
当采用相干方式传输数据时,所述网络侧设备将所有的所述数据层映射 到一个QCL分组中;
当采用非相干方式传输数据时,所述网络侧设备将所有的所述数据层映射到至少两个QCL分组上。
其中,在第四种情况下,同一数据层子集中的不同数据层可以映射到不同的QCL分组上,也可以映射到相同QCL分组上,具体设置方式可以根据实际需要进行设置。例如,在第四种情况中,上述步骤202还包括:所述网络侧设备将同一所述数据层子集中的不同数据层映射到不同的QCL分组上。
针对上述第三种情况和第四种情况中,每一个QCL分组中可以设置限制码字的数量,根据该码字的限制数量对QCL分组的映射关系进行布局。具体的,在上述步骤202之前,所述方法还可以包括:所述网络侧设备预先配置每一QCL分组上的码字数量的限定值。
应当说明的是,上述网络侧设备将所有的所述数据层映射到一个QCL分组中时,可以在不同的传输时隙中可以进行传输切换。例如可以在不同的传输时隙中进行QCL分组切换,也可以在不同的传输时隙中在同一QCL分组的不同天线资源上进行切换。例如,可以是这样的:在第一个传输时隙中采用QCL分组1进行输出传输,在第二传输时隙中采用QCL分组2进行数据传输。还可以是这样的:在第一个传输时隙中采用QCL分组中天线端口1至5进行数据传输,在第二传输时隙中采用QCL分组中天线端口6至10进行数据传输。应理解,对于输出传输切换的方式可以根据实际需要进行设置,在此不做进一步的限定。
具体的,上述同一所述QCL分组的天线端口上传输的信号,所经历的信道的大尺度参数对应的参数值位于同一预设范围内。其中,大尺度参数包括平均增益、平均时延、时延扩展、平均到达角和到达角扩展中的至少一项。
在本实施例中,从具有QCL关系的各天线端口上发送的信号所经历的信道,其大尺度参数可以被认为基本一致。也就是说,从这些大尺度信道参数角度而言,这些天线端口可以被认为是“位置相同的”。从而将认为位置相同的天线端口假设其QCL,使得位置相同的天线端口位于同一QCL分组。另外,对于不同QCL分组的天线端口,将不假设其QCL。
可选的,对于QCL分组的方式可以根据实际需要进行设置,例如可以由 终端侧设备对基站的天线端口进行QCL分组,也可以由基站对自身的天线端口进行QCL分组,以下对此进行详细说明:

步骤204、所述网络侧设备接收终端侧设备发送的上行参考信号。
步骤205、所述网络侧设备根据所述上行参考信号进行上行参考信号测量。
步骤206、所述网络侧设备根据测量的结果确定所述各天线端口的QCL关系。
步骤207、所述网络侧设备根据所述QCL关系对所述天线端口进行分组,得到至少一QCL分组。
本实施例中,可以利用网络侧设备在对终端侧设备的上行参考信号测量时,测量的结果进行QCL分组。例如由终端侧设备进行上行参考信号的发送,网络侧设备在接收到上行参考信号后,可以进行测量配置,以对终端侧设备的波束训练进行测量。根据测量的结果,网络侧设备可以确定自身各天线端口的关系,从而对天线端口进行分组,形成至少一QCL分组。上述上行参考信号可以终端侧设备主动发送给网络侧设备,由网络侧设备进行测量。也可以由网络侧设备发送相应的控制信令至终端侧设备,触发终端侧设备发送上行参考信号给网络侧设备,由网络侧设备进行测量。

本实施例中,可以由终端侧设备进行下行参考信号的测量,基于测量结果对网络侧设备的天线端口进行QCL关系的假设,从而进行QCL分组。例如每个QCL分组中,可以假设各天线端口之间的QCL,对于不同QCL分组的天线端,不假设其QCL。最后将QCL分组的方式上报到网络侧设备中, 由网络侧设备建立各天线端口的分组关系。

所述网络侧设备接收所述终端侧设备基于所述测量配置信息对所述CSI指示信号进行测量所上报的测量结果。
本实施例中,相干传输方式和非相干传输方式的不同,对应每一QCL分组发送的CSI指示信号也不同。例如在相干传输方式中,可以配置每一QCL分组发送不同的CSI指示信号。在非相干传输方式中,可以由至少一个QCL分组构成的组合进行CSI至少信号的发送。例如,可以配置每一QCL分组组合发送不同的CSI指示信号。
终端侧设备可以根据网络侧设备发送的测量配置信息进行CSI的测量,然后将测量结果上报到网络侧设备,由于传输方式不同,对应的计算测量结果上报的方式也不同:
例如当所述终端侧设备基于所述相干传输方式,计算所述测量配置信息中待测量信道的CSI时,可以向网络侧设备上报一个或者多个QCL分组对应的CSI。当所述终端侧设备基于所述非相干传输方式,计算所述测量配置信息中待测量信道的CSI时,可以向网络侧设备上报一个或者多个QCL分组组合对应的CSI。
本实施例中,上述CSI包括信道质量信息和推荐传输参数,该推荐传输参数可以包括:PMI(Precoding Matrix Indicator,预编码矩阵指示)和RI(rank indication,秩指示)等。

在本实施例中,从具有QCL关系的各天线端口上发送的信号所经历的信道,其大尺度参数可以被认为基本一致。也就是说,从这些大尺度信道参数角度而言,这些天线端口可以被认为是“位置相同的”。从而将认为位置相同的天线端口假设其QCL,使得位置相同的天线端口位于同一QCL分组。另 外,对于不同QCL分组的天线端口,将不假设其QCL。
可选的,对于QCL分组的方式可以根据实际需要进行设置,例如可以由终端侧设备对基站的天线端口进行QCL分组,也可以由基站对自身的天线端口进行QCL分组,以下对此进行详细说明:
