上行发送方法和发送端

技术领域
本公开涉及通信技术领域，尤其涉及一种上行发送方法和发送端。
背景技术
新空口(New Radio，NR)系统中，正在研究上行异步发送的场景，其中，上行异步发送是指发送端发送上行数据时与接收端上行不同步。另外，目前NR正在研究非正交多址技术，采用非正交多址技术，不同发送端的数据可以在相同的时频资源上进行发送。因此，为了辅助接收端分离不同终端的信号，发送端使用多址接入签名(Multi Access signature，MA signature)对数据进行处理。可选地，发送端还发送解调参考信号(DeModulation Reference Signal，DMRS)。另外，在上行异步发送过程中，发送端还需要向接收端发送前导码(preamble)。由于上行异步发送是NR系统中新引入，因此，preamble、DMRS和/或MA signature的确定方法目前还未确定，从而导致发送端的传输性能比较低。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
参见图1，图1是本公开实施例可应用的网络结构示意图，如图1所示，包括发送端11和接收端12，其中，发送端11可以为终端，终端可以是用户终端(User Equipment，UE)或者其他终端设备，例如：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发送端的具体类型。接收端12可以是网络侧设备，网络侧设备可以是基站，例如：宏站、LTE eNB、5G NR NB等；网络侧设备也可以是小站，如低功率节点(LPN：low power node)、pico、femto等小站，或者网络侧设备可以接入点(AP，access point)；基站也可以是中央单元(CU，central unit)与其管理是和控制的多个传输接收点(TRP，Transmission Reception Point)共同组成的网络节点。需要说明的是，在本公开实施例中并不限定接收端的具体类型。
请参见图2，图2是本公开实施例提供的一种上行发送方法的流程图，如图2所示，包括以下步骤：
201、发送端确定preamble；
202、所述发送端根据所述preamble，确定DMRS和/或MA signature；
203、所述发送端发送所述preamble，以及根据所述DMRS和/或所述MA signature发送上行数据。
其中，上述确定preamble可以是在多个preamble中选择一个preamble，例如：步骤201可以包括：发送端从preamble资源池选择所述preamble。其中，该preamble资源池可以是预先配置好的，例如：发送端在确定preamble之前，获取preamble资源池配置，从而在确定时，根据该preamble资源池配置在preamble资源池中选择上述preamble。由于在preamble资源池中选择上述preamble，从而可以提高发送端上行发送的灵活性，因为，发送端可以根据实际需求选择对应的preamble。
当然，本公开实施例中，并不限定在preamble资源池中选择上述preamble，例如：还可以是发送端预先配置好上述preamble。
上述根据所述preamble，确定DMRS和/或MA signature可以是，根据preamble与DMRS和/或MA signature的对应关系，确定该preamble对应的DMRS和/或MA signature。具体可以是，确定preamble对应的DMRS或者MA signature，或者确定preamble对应的DMRS和MA signature。
另外，本公开实施例中，DMRS可以包括：DMRS端口和/或DMRS序列，其中，不同的DMRS至少DMRS端口和DMRS序列中的一个不相同。而MA signature用于区分相同资源上不同发送端的信号，MA signature可以包括如下至少一项：

序列；
交织图样和/或映射图样等。
而上述根据所述DMRS和/或所述MA signature发送上行数据可以是，根据步骤202确定DMRS和/或MA signature发送上行数据。例如：步骤202确定DMRS，则步骤203根据DMRS发送上行数据，若步骤202确定MA signature，则步骤203根据MA signature发送上行数据，若步骤202确定DMRS和MA signature，则步骤203根据DMRS和MA signature发送上行数据。
另外，上述发送端发送所述preamble和上行数据可以是，采用上行异步发送的方式发送preamble和上行数据。且上述preamble和上行数据可以是在连续的时域资源上发送，或者可以是先发送preamble，在接收到接收端返回的对应preamble的响应后，再发送上行数据。
通过上述步骤可以提高发送端的传输性能，另外，由于DMRS和/或MA signature与preamble对应，从而接收端可以根据preamble确定上述DMRS和/或MA signature，以避免接收端检测出preamble后还需要进行不同的DMRS和/或MA signature假设，进而降低接收端的复杂度，同时也提高接收端的检测性能。

一个preamble对应一个MA signature，或者一个preamble对应一组MA signature，其中，所述第二对应关系包括一个preamble对应一组MA signature时，所述确定所述preamble对应的MA signature为，在所述preamble对应的一组MA signature中确定一个MA signature；
例如：发送端获取preamble资源池配置，以及preamble与MA signature的对应关系；发送端在所述preamble资源池中选择一个preamble，根据 preamble与MA signature的对应关系确定所选择的preamble对应的MA signature；之后，发送端可以采用所述preamble以及对应的MA signature进行上行发送。
具体地，发送端可以根据网络侧通知获取preamble资源池配置，所述preamble资源池包括一组preamble。
发送端可以根据协议约定或者网络侧的通知确定preamble与MA signature的对应关系。其中，Preamble与MA signature的对应关系可以参见上述介绍的preamble与DMRS的对应关系，即存在一个preamble对应一个MA signature以及一个preamble对应多个MA signature。若一个preamble对应一个MA signature，则发送端根据确定的preamble唯一得确定对应的MA signature；若一个preamble对应多个MA signature，可选地，发送端进一步地在所述一组MA signature中选择一个MA signature。
其中，上述所述MA signature用于区分相同资源上不同UE的信号，包括下列中的一个或者多个：
码本/码字；

所述发送端根据preamble、DMRS和MA signature的第三对应关系，确定所述preamble对应的DMRS和MA signature。
该实施方式中，可以是在确定DMRS之前发送端获取到上述第三对应关系，从而在发送上行数据之前采用该第三对应关系，确定所述preamble对应的DMRS和MA signature，这样可以降低接收端的复杂度、提高了接收端的检测性能。
可选的，所述第三对应关系可以包括如下情况：
