用于上行数据传输的方法和终端设备 技术领域
本申请涉及通信领域，尤其涉及用于上行数据传输的方法和终端设备。
背景技术
在新无线(new radio，NR)系统中，终端设备可以使用多个天线阵列块(panel)进行上行数据传输，一个panel包含一组物理天线，每个panel有独立的射频通道。终端设备可以同时在多个panel上传输数据，但由于不同panel对应的信道条件是不同的，不同的panel需要根据各自的信道信息采用不同的传输参数，例如不同的panel可以有不同的波束、预编码和发送功率等。
为了获得这些传输参数，需要为不同的panel配置不同的信道探测参考信号(sounding reference signal，SRS)资源集合，进而获得上行信道信息。那么如何让终端设备获取当前数据传输对应的SRS资源集合和所用的传输参数是需要解决的问题。

应理解，本申请实施例中的终端设备可以有一个或多个天线阵列块(panel)用于上行数据传输，每个panel有独立的射频通道。
对应地，该多个参考信号资源集合可以用于多个天线阵列块上的参考信号传输，其中，不同的参考信号资源集合可以用于不同的panel上的参考信号的传输。

因此，终端可以同时检测至少两个DCI，分别调度不同panel上的数据传输，从而支持不同panel同时进行上行传输，提高上行传输的频谱效率。
应理解，接收第一DCI的同时接收第二DCI可以包括：终端设备在同一时隙中接收该第一DCI和第二DCI，或者，该终端设备在同一OFDM符号中接收该第一DCI和第二DCI，或者该终端设备在同一控制信道中检测到该第一DCI和第二DCI，本申请实施例并不限于此。
应理解，该第二DCI包括第二参考信号资源集合指示信息；对应的，该方法100还包括：终端设备根据该第二参考信号资源集合指示信息，确定第二参考信号资源集合，该第二参考信号资源集合与该第一参考信号资源集合不同。
在本申请实施例中，一个DMRS端口组可以对应一个panel，一个panel可以对应多个DMRS端口，终端设备在确定一个panel的传输参数之后，就可以在这一天线阵列块上传输相应DMRS端口组上的数据。对应的，终端设备通过该第一DCI调度的该第一上行数据传输与通过该第二DCI调度的第二上行数据传输可以使用不同的DMRS端口。
例如，第一DCI调度第一上行传输，且第一上行传输采用DMRS端口0和端口1；第二DCI调度第二上行传输，且第二上行传输采用DMRS端口2和端口3。
因此，本申请实施例的用于上行数据传输的方法，终端设备接收网络设备发送的多个DCI，不同DCI用于调度不同的panel上的上行传输，根据不同DCI中指示不同的资源集合，确定对应的panel的上行信道信息，可以使得多个panel可以采用独立的传输参数进行数据传输，从而可以提高多panel传输的灵活性和上行频谱效率。
