Description

数据传输的方法和设备Method and device for data transmission

技术领域Technical field

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设备。Embodiments of the present invention relate to the field of communications and, more particularly, to methods and apparatus for data transmission.

背景技术Background technique

在长期演进的非授权载波(Licensed-Assisted Access Using Long Term Evolution，LAA-LTE)***中，节点需要通过说前先听(Listen Before Talk，LBT)来使用非授权载波的信道资源，其中，LBT是一种载波监听多路访问(Carrier Sense Multiple Access，CSMA)技术，即节点需要与其它节点竞争非授权载波的资源，并且只有在竞争到该非授权载波的资源时，才能使用该非授权载波的资源。因为非授权载波信道占用的开始时间点是随机的，所以LAA-LTE子帧占用非授权载波信道的开始时间点也是随机的，那么LAA-LTE子帧占用非授权载波信道的开始时间和授权载波信道上子帧占用授权载波信道的子帧边界就会不对齐。In a Licensed-Assisted Access Using Long Term Evolution (LAA-LTE) system, a node needs to use channel resources of an unlicensed carrier by using Listen Before Talk (LBT), where LBT It is a carrier sense multiple access (CSMA) technology, that is, a node needs to compete with other nodes for resources of an unlicensed carrier, and can only use the unlicensed carrier when competing for resources of the unlicensed carrier. resource of. Since the start time point occupied by the unlicensed carrier channel is random, the start time point of the LAA-LTE subframe occupying the unlicensed carrier channel is also random, and the LAA-LTE subframe occupies the start time of the unlicensed carrier channel and the authorized carrier. The subframe boundaries on the channel occupying the licensed carrier channel are not aligned.

因此，如图1所示，节点可能会先在非授权载波信道上发送一个不完整的子帧，这个不完整的子帧的时间一直持续到授权载波信道上对应子帧的结束时间，然后开始在非授权载波信道上发送完整的子帧。也就是说，非授权载波信道上的第一个子帧不完整，接下来的子帧是完整的，并且非授权载波信道上除第一个子帧外其他子帧和授权载波信道上的子帧在时间上是对齐的，但是最后一个子帧也可能是不完整的。那么如何正确接收最后一个不完整子帧的数据成为一个亟待解决的问题.Therefore, as shown in FIG. 1, the node may first send an incomplete subframe on the unlicensed carrier channel, and the time of the incomplete subframe continues until the end time of the corresponding subframe on the authorized carrier channel, and then begins. A complete subframe is transmitted on the unlicensed carrier channel. That is, the first subframe on the unlicensed carrier channel is incomplete, the next subframe is complete, and the subcarriers on the unlicensed carrier channel except the first subframe and the subcarriers on the licensed carrier channel Frames are aligned in time, but the last subframe may also be incomplete. So how to correctly receive the data of the last incomplete subframe becomes an urgent problem to be solved.
