Description

传输上行数据的方法、终端设备和网络设备 技术领域
本发明实施例涉及无线通信领域，并且更具体地，涉及一种传输上行数据的方法、终端设备和网络设备。
背景技术
目前在5G系统的上行传输过程中引入了多种上行多址接入方式，例如离散傅里叶变换扩频的正交频分复用(Discrete Fourier Transformation Spread Orthogonal Frequency Division Multiplexing，简称“DFT-S-OFDM”)多址接入技术和循环前缀正交频分复用(Cyclic Prefix Orthogonal Frequency Division Multiplexing，简称“CP-OFDM”)等。前者只能用于上行单层传输，后者可以用于上行单层或者上行多层传输。终端设备使用哪一种多址方式可以由网络侧设备根据终端设备的上行信道质量进行配置，因此网络侧设备如何通知终端设备其使用的上行多址接入方式是急需解决的问题。
发明内容
本发明实施例提供了一种传输上行数据的方法、终端设备和网络设备，终端设备能够在进行上行传输时获知自己使用的上行多址接入方式。
第一方面，提供了一种传输上行数据的方法，其特征在于，包括：终端设备接收网络设备发送的承载在下行控制信息DCI中的参数指示信息；所述终端设备根据所述参数指示信息，确定所述终端设备的传输信息，所述传输信息包括所述终端设备的传输层数和/或物理资源配置方式；所述终端设备根据所述传输信息，确定所述终端设备的上行多址接入方式；所述终端设备根据所述上行多址接入方式，传输所述上行数据。
这样，终端设备通过DCI中的参数指示信息确定终端设备的传输层数和/或物理资源配置方式，并根据该传输层数和/或该物理资源配置方式来确定上行多址接入方式，从而实现了网络设备在单层传输时灵活调整终端设备所使用的上行多址接入方式。
可选地，在第一方面的一种实现方式中，所述参数指示信息包括以下信息中的至少一种：传输层数指示信息、物理资源配置方式指示信息、解调参 考信号DMRS端口指示信息、预编码矩阵PMI指示信息和码字指示信息。
一种方式为，网络设备通过该参数指示信息直接向终端设备指示该终端设备的传输信息，例如该参数指示信息可以为传输层数指示信息或者物理资源配置方式指示信息。则终端设备接收到该传输层数指示信息后，就可以直接确定自己的传输层数，或者在接收到该物理资源配置方式指示信息后，就可以直接确定自己的物理资源配置方式。
另一种方式为，网络设备可以通过该参数指示信息间接地向终端设备指示该终端设备的传输信息，例如该参数指示信息可以为解调参考信号DMRS端口指示信息、预编码矩阵PMI指示信息或码字指示信息。
可选地，在第一方面的一种实现方式中，所述传输信息包括所述终端设备的传输层数，其中，所述终端设备根据所述传输信息，确定所述终端设备的上行多址接入方式，包括：若所述终端设备确定所述传输层数为1，则所述终端设备根据承载在所述DCI中的信息，确定所述终端设备的上行多址接入方式。

可选地，在第一方面的一种实现方式中，所述终端设备根据承载在所述DCI中的信息，确定所述终端设备的上行多址接入方式，包括：所述终端设备根据承载在所述DCI中的被关闭码字的调制编码方式MCS指示信息，确定所述上行多址接入方式。
该MCS指示信息在传输层数大于1或该被关闭码字被使能时，可以用于指示该被关闭码字所传输的数据的调制编码方式。

本发明实施例中，采用上述几种方式来指示终端设备的上行多址接入方式，不需要在DCI中添加专用的比特用于指示上行多址接入方式，从而不会增加DCI的净负荷(Payload)，从而提高了DCI的检测性能。
应理解，终端设备确定传输层数、物理资源配置方式和上行多址接入方式的过程中所用到的参数之间的对应关系例如DMRS端口数与传输层数的对应关系、DMRS配置信息的取值与DMRS配置和多址接入方式的对应关系等，可以由网络设备和终端设备事先约定例如按照协议的规定，也可以由网络设备自行确定并通知终端设备，本发明实施例对此不作限定。

图2是根据本发明实施例的传输上行数据的方法的流程交互图。图2示出了网络设备和终端设备，该网络设备例如可以为图1中所示的网络设备10，该终端设备例如可以为图1中所示的终端设备20。本发明实施例中，终端设备可以根据下行控制信息(Download Control Information，简称“DCI”)中的参数指示信息确定终端设备的传输层数和/或物理资源配置方式，并根据该传输层数和/或该物理资源配置方式来确定上行多址接入方式，从而实现网络设备在单层传输时灵活调整终端设备所使用的上行多址接入方式。
如图2所示，该传输上行数据的具体流程包括：
210，网络设备确定参数指示信息。
其中，该参数指示信息可以承载在DCI中。
220，网络设备向终端设备发送该参数指示信息。
具体地说，网络设备为终端设备配置好了该终端设备使用的上行多址接入方式后，可以在向终端设备发送DCI时，通过承载在DCI中的参数指示信息，向终端设备指示该传输层数和/或该物理资源配置方式。
230，终端设备接收网络设备发送的该参数指示信息。
可选地，该参数指示信息可以包括以下中的至少一种：传输层数指示信息、物理资源配置方式指示信息、解调参考信号(DeModulation Reference Signal，简称“DMRS”)端口指示信息、预编码矩阵(Precoding Matrix Indicator，简称“PMI”)指示信息和码字指示信息。

具体地说，终端设备接收到网络设备发送的该参数指示信息后，根据该参数指示信息，确定该终端设备的传输信息，例如该终端设备传输层数/或物理资源配置方式。
一种方式为，网络设备通过该参数指示信息直接向终端设备指示该终端设备的传输信息，例如该参数指示信息可以为传输层数指示信息或者物理资源配置方式指示信息。则终端设备接收到该传输层数指示信息后，就可以直接确定自己的传输层数，或者在接收到该物理资源配置方式指示信息后，就可以直接确定自己的物理资源配置方式。
例如，网络设备向终端设备发送的DCI中，可以有2比特用于指示传输层数。比如该2比特的值为00指示传输层数1，该2比特的值为01指示传输层数为2，该2比特的值为10指示传输层数3，该2比特的值为11指示传输层数为4。
又例如，网络设备向终端设备发送的DCI中，可以有1比特用于指示物理资源配置方式。比如该1比特的值为0指示物理资源配置方式1，该1比特的值为1指示物理资源配置方式2。
另一种方式为，网络设备可以通过该参数指示信息间接地向终端设备指示该终端设备的传输信息，例如该参数指示信息可以为解调参考信号DMRS 端口指示信息、预编码矩阵PMI指示信息或码字指示信息。
例如，该DMRS端口指示信息用于指示DMRS端口数，终端设备接收到DMRS端口指示信息后，可以知道对应的DMRS端口数，并根据该DMRS端口数与来确定自己的传输层数。比如终端设备根据该DMRS端口数，以及DMRS端口数与传输层数的对应关系，确定该终端设备的传输层数。或者，网络设备也可以在DCI中通过DMRS端口指示信息将DMRS端口数和传输层数联合指示。
又例如，网络设备可以在DCI中将PMI和终端设备的传输层数联合编码，从而终端设备接收到PMI指示信息后，可以从该PMI指示信息至获取自己的传输层数的信息。
又例如，该码字指示信息用于指示传输码字数，终端设备接收到码字指示信息后，可以知道对应的传输码字数，并根据传输码字数来确定自己的传输层数。比如终端设备根据该传输码字数，以及传输码字数与传输层数的对应关系，确定该终端设备的传输层数。
250，终端设备根据该传输信息，确定终端设备的上行多址接入方式。
可选地，该上行多址接入方式包括以下中的任意一种：离散傅里叶变换扩频的正交频分复用DFT-S-OFDM、循环前缀正交频分复用CP-OFDM、单载波频分多址接入(Single-carrier Frequency-Division Multiple Access，简称“SC-FDMA”)和正交频分多址接入(Orthogonal Frequency Division Multiple Access，简称“OFDMA”)。
该传输信息可以包括传输层数和/或物理资源配置方式。下面分别对传输信息包括传输层数，和传输信息包括物理资源配置方式进行详细描述。
情况1该传输信息包括传输层数
可选地，终端设备根据传输信息，确定终端设备的上行多址接入方式，包括：若终端设备确定该传输层数大于1，则终端设备确定该上行多址接入方式为与网络设备预先约定好的上行多址方式。
可选地，终端设备根据传输信息，确定终端设备的上行多址接入方式，包括：若终端设备确定该传输层数为1，则终端设备根据承载在DCI中的信息，确定终端设备的上行多址接入方式。
也就是说，当终端设备的传输层数为1时，终端设备可以采用上述多种多址接入方式中的任意一种；当终端设备的传输层数大于1时，终端设备采 用与网络设备预先约定好的上行多址方式。下面具体说明终端设备如何根据承载在DCI中的信息，确定终端设备的上行多址接入方式。
但是，应理解，本发明实施例中，终端设备也可以在确定该传输层数满足一定要求时自行确定上行多址接入方式，例如满足传输层数小于n的条件时，根据承载在DCI中的信息，确定终端设备的上行多址接入方式；而确定该传输层数大于n时，采用与网络设备预先约定好的上行多址方式，其中n为大于1的正整数。
可选地，终端设备根据承载在DCI中的信息，确定终端设备的上行多址接入方式，包括：终端设备根据承载在该DCI中的DMRS配置指示信息，确定该上行多址接入方式，该DMRS配置指示信息是对DMRS配置的信息与该上行多址接入方式的信息进行联合编码得到的。
也就是说，网络设备在向终端设备发送承载在DCI中的DMRS配置指示信息之前，还包括：网络设备对DMRS配置的信息和该上行多址接入方式进行联合编码，以得到该RI指示信息。
假设该DMRS配置信息为3比特，则不同DMRS配置指示信息所指示的内容例如可以为表一所示。其中，DMRS配置1和DMRS配置2分别为传输层数为1时的DMRS配置，并且，DMRS配置3至DMRS配置6分别对应传输层数大于1时的DMRS配置。
表一

1 DMRS配置1，多址接入方式2
2 DMRS配置2，多址接入方式1
3 DMRS配置2，多址接入方式2
4 DMRS配置3
5 DMRS配置4
6 DMRS配置5
7 DMRS配置6
可以看出，DMRS配置指示信息为0时，指示终端设备采用DMRS配置1且使用多址接入方式1，DMRS配置指示信息为1时，指示终端设备采用DMRS配置1且使用多址接入方式2，DMRS配置指示信息为2时，指示终端设备采用DMRS配置2且使用多址接入方式1，DMRS配置指示信息为3时，指示终端设备采用DMRS配置2且使用多址接入方式2。DMRS配置 指示信息为4时，指示终端设备采用DMRS配置3，DMRS配置指示信息为5时，指示终端设备采用DMRS配置4，DMRS配置指示信息为6时，指示终端设备采用DMRS配置5，DMRS配置指示信息为7时，指示终端设备采用DMRS配置6。

该NDI比特在传输层数大于1或该被关闭码字被使能时，可以用于指示该被关闭码字所传输的数据是否为重传数据。
例如，可以通过表二的方式来确定该NDI比特的含义。
表二

可选地，终端设备根据承载在DCI中的信息，确定终端设备的上行多址接入方式，包括：终端设备根据承载在该DCI中的被关闭码字的调制编码方式MCS指示信息，确定该上行多址接入方式。
该MCS指示信息在传输层数大于1或该被关闭码字被使能时，可以用于指示该被关闭码字所传输的数据的调制编码方式。
例如，当传输层数为1时，如果被关闭码字的调制编码方式MCS指示信息为A，则可以指示终端设备的该上行多址接入方式为上行多址方式1，如果被关闭码字的调制编码方式MCS指示信息为B，则可以指示终端设备的该上行多址接入方式为上行多址方式2。
可选地，终端设备根据承载在所述DCI中的信息，确定终端设备的上行多址接入方式，包括：终端设备根据承载在DCI中的秩指示RI指示信息，确定上行多址接入方式，其中，该RI指示信息是对RI的值与该上行多址接 入方式的信息进行联合编码得到的。
也就是说，网络设备在向终端设备发送承载在DCI中的RI指示信息之前，还包括：网络设备对RI的值和该上行多址接入方式进行联合编码，以得到该RI指示信息。
假设承载在DCI中的RI的值为2比特，且终端设备最高支持的RI指示信息占用2比特，则不同的RI指示信息所指示的内容例如可以为表三所示。
表三
RI指示信息 RI指示信息所指示的内容
0 RI＝1，指示多址接入方式1
1 RI＝1，指示多址接入方式2
2 RI＝2
3 Reserved
可选地，终端设备根据承载在所述DCI中的信息，确定终端设备的上行多址接入方式，包括：终端设备根据承载在DCI中的填充(padding)比特的值，确定该上行多址接入方式。
其中，该padding比特是为了保持与其他DCI格式的长度相同，而在该DCI中加入的冗余比特。
可选地，终端设备根据承载在所述DCI中的信息，确定终端设备的上行多址接入方式，包括：终端设备根据承载在DCI中的物理资源配置方式指示信息，确定该上行多址接入方式。
本发明实施例中，采用上述几种方式来指示终端设备的上行多址接入方式，不需要在DCI中添加专用的比特用于指示上行多址接入方式，从而不会增加DCI的净负荷(Payload)，从而提高了DCI的检测性能。
应理解，上述的表一至表三，以及终端设备确定传输层数、物理资源配置方式和上行多址接入方式过程中所用到的参数之间的对应关系例如DMRS端口数与传输层数的对应关系、DMRS配置信息的取值与DMRS配置和多址接入方式的对应关系等，可以由网络设备和终端设备事先约定例如按照协议的规定，也可以由网络设备自行确定并通知终端设备，本发明实施例对此不作限定。

其中，物理资源配置方式与上行多址接入方式的对应关系，可以由网络设备和终端设备事先约定例如按照协议的规定，也可以由网络设备自行确定并通知终端设备，这里不作限定。

具体地说，终端设备与网络设备可以预先约定好上行多址方式与上行数据信道结构的对应关系，并采用该终端设备的上行多址方式对应的上行数据信道结构，来传输该上行数据。
举例来说，该上行数据信道结构可以包括该上行数据信道的DMRS资源位置，例如DMRS是占用整个正交频分复用(Orthogonal Frequency Division Multiplexing，简称“OFDM”)符号还是占用OFDM符号上的部分子载波；该上行数据信道结构可以包括该上行数据信道的DMRS序列，不同的上行数据信道结构可以采用不同的DMRS序列；该上行数据信道结构还可以包括该上行数据采用的预编码矩阵，例如该上行数据是采用宽带预编码矩阵还是采用子带预编码矩阵；该上行数据信道结构还可以包括该上行数据信道所占用的OFDM符号数等。
