Description

数据传输的方法和装置 技术领域
本发明实施例涉及通信领域，并且更具体地，涉及数据传输的方法和装置。
背景技术
分集是接收端对它收到的衰落特性相互独立地进行特定处理，以降低信号电平起伏的办法。分集是指分散传输和集中接收。所谓分散传输是使接收端(例如，终端设备)能获得多个统计独立的、携带同一信息的衰落信号。集中接收是接收机把收到的多个统计独立的衰落信号进行合并(选择与组合)以降低信号在传输时的信号衰落的对信号传输质量的影响。在移动通信中，通常采用分集技术来补偿衰落信道损耗，可以在不增加传输功率和带宽的前提下，改善无线通信信道的传输质量。
在长期演进(Long Term Evolution，LTE)通信系统中，终端在通过对物理广播信道(Physical Broadcast Channel，PBCH)进行盲检，确定传输后续数据使用的传输分集的方式后，终端会使用该传输分集的方式传输后续数据，并且该终端传输数据所使用的传输分集的方式就固定了，也就是说，上述这种固定分集传输的方式的数据传输方法，降低了数据传输方式的灵活性。

具体地，上述第一传输分集的方式可以是空间频率块码-频率选择性发送分集(Space Frequency Block Code-Frequency Switch Transmit Diversity，SFBC-FSTD)或SFBC，还可以是其他未来通信标准中规定的传输分集的方式，本发明实施例对传输分集的方式不作具体限定。

具体地，终端在接收到指示信息之前，可以以SFBC的传输分集的方式接收数据，当该终端接收到用于指示终端以第一传输分集的方式传输书记的指示信息后，该终端可以以第一传输分集的方式接收数据。
可选地，作为一个实施例，所述第一数据是通过第一波束和第二波束向所述终端发送的，所述第一波束为所述终端切换至所述第二波束之前为所述终端提供服务的源波束，所述第二波束为所述终端切换至的目标波束。
具体地，上述为终端提供服务的波束可以指该终端可以使用该波束传输数据。
需要说明的是，若上述第一波束对应的2天线端口，上述第二波束也对应的2天线端口，则网络侧设备通过第一波束和第二波束向终端发送第一数据时，网络侧设备可以通过指示信息向终端指示使用4天线端口对应的传输分集的方式(可以是SFBC-FSTD)接收第一数据。
可选地，终端向网络侧设备发送位置信息，该位置信息用于指示该终端的当前位置，以便网络侧设备根据该终端的当前位置信息确定该终端是否位 于所述第一波束和所述第二波束之间的切换区。

可选地，网络侧设备可以自行判断终端的位置，该位置信息用于指示该终端的当前位置，以便网络侧设备根据该终端的当前位置信息确定该终端是否位于所述第一波束和所述第二波束之间的切换区。
具体地，上述第一波束和第二波束之间的切换区可以指第一波束的覆盖范围和第二波束的覆盖范围的重叠区域。

需要说明的是，上述第一TRP和第二TRP分别属于不同的小区时，第一TRP所在的网络侧设备和第二TRP所在的网络侧设备之间可以通过预先约定(或协商)的方式，确定该终端传输数据使用的传输分集的方式。
应理解，上述第一TRP和第二TRP分别属于不同的小区时，第一TRP所在的网络侧设备或第二TRP所在的网络侧设备都可以向该终端发送上述指示信息，本发明实施例对此不作具体限定。
