本申请主张在2017年5月4日在中国提交的中国专利申请号No.201710307917.X的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别涉及一种预编码矩阵指示方法、终端和网络侧设备。
背景技术
在通信系统(例如：NR系统)因为终端发射天线数目较多，且终端的计算能力提升，所以考虑在上行数据发送采用子带预编码，即终端在被调度上行发送数据的频率资源上按照一个小的子带进行预编码，且不同子带上使用不同的预编码矩阵，这个称之为子带预编码。但因为被调度资源大小是可变的因而子带个数也是可变的，这样导致网络侧设备的预编码通知的控制信令比特数是根据子带的个数变化的。比如：以终端发射天线数目为2，且预编码矩阵指示为3比特进行举例，如果网络侧设备调度了1个子带大小的频率资源，那么网络侧设备需要用3比特的控制信令通知终端预编码矩阵，如果网络侧设备调度了2个子带大小的频率资源，那么网络侧设备需要用6比特(每个子带3比特)的控制信令通知终端预编码矩阵。但由于终端接收网络侧设备发送的控制信令是通过盲检，这样控制信令长度变化会增加终端接收控制信令的盲检复杂度。可见，目前终端接收控制信令的盲检复杂度较高。

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为本公开实施例可应用的网络结构示意图，如图1所示，包括终端11和网络侧设备12，其中，终端11可以是手机、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终端11的具体类型。终端11可以与网络侧设备12建立通信，其中，附图中的网络可以表示终端11与网络侧设备12无线建立通信，网络侧设备12可以是演进型基站(eNB，evolved Node B)或者其他基站，或者可以是接入点设备等网络侧设备，需要说明的是，在本公开实施例中并不限定网络侧设备12的具体类型。
请参考图2，本公开实施例提供一种预编码矩阵指示方法，如图2所示，包括以下步骤：201、终端接收网络侧设备发送的控制信令，所述控制信令包括N比特的预编码信息，所述N为正整数；202、所述终端根据调度资源确定预编码颗粒的数目，并根据所述预编码颗粒的数目在所述N比特的预编码信息中确定每个预编码颗粒的预编码信息比特，其中，每个预编码颗粒包括至少一个子带，且每个子带包括至少一个PRB；203、所述终端获取每个预编码颗粒的预编码信息比特指示的预编码矩阵。
其中，上述控制信令可以是用于进行预编码矩阵指示的控制信令，当然，上述控制信令除了上述N比特的预编码信息之外，还可以包括其他信息，且这些其他信息的比特数也是固定的，从而保证控制信令的总比特数是固定的。
另外，上述N可以是网络侧设备预先配置的，或者协议规定的或者网络侧设备与终端预先协商的等等，例如：N为10或者20或者30等等。由于，本公开实施例中，控制信令中预编码信息的比特数N，即固定长度或者长度不可变的预编码信息，从而可以降低终端接收控制信令的盲检复杂度。另外，本公开实施例中，针对不同终端或者不同业务，均可以采用相同比特数的预编码信息。
上述调度资源可以是网络侧设备向上述终端调度的资源或者为上述用户终端分配的资源，该资源中可以包括一个或者多个预编码颗粒，每个预编码颗粒可以包括一个或者多个子带，每个子带包括至少一个PRB，且同一个预编码颗粒内的子带采用相同的预编码矩阵。且本公开实施例中，不同预编码颗粒包括的子带个数可以是相同或者不同的，对此本公开实施例不作限定。
上述根据调度资源确定预编码颗粒的数目可以是确定上述调度资源的预编码颗粒的数目，即确定该调度资源包括多少个预编码颗粒，其中，确定的方式可以是根据预先获取的对应关系确定，或者可以是根据调度资源的大小信息确定等，对此本公开实施例不作限定。
上述根据所述预编码颗粒的数目在所述N比特的预编码信息中确定每个预编码颗粒的预编码信息比特可以是，根据预编码颗粒的数目与预编码信息比特的比特数目的对应关系，确定预编码信息比特的比特数目，再根据比特数目确定各预编码颗粒的预编码信息。例如：按照预编码颗粒的频域或者时域顺序，在上述N比特的预编码信息确定各预编码颗粒的预编码信息比特。如预编码颗粒1按照频域或者时域的顺序在预编码颗粒2的前面，而上述N为10，上述比特数目为5，则可以确定前5个比特为预编码颗粒1的预编码信息比特，后5个比特为预编码颗粒2的预编码信息比特。当然，本公开实施例中并不限定通过上述顺序来确定各预编码颗粒的预编码信息比特，例如：还可以通过预编码颗粒与预编码信息比特位置的对应关系确定各预编码颗粒的预编码信息比特。
其中，预编码信息比特可以是预编码矩阵的索引或者指示信息，这样终端获取每个预编码颗粒的预编码信息比特后，就可以直接获取各预编码颗粒的预编码矩阵。且每个预编码颗粒的预编码矩阵为各自预编码信息比特指示 的预编码矩阵。
在上述步骤中，根据预编码颗粒的数目，确定每个预编码颗粒的预编码信息比特，从而可以实现预编码颗粒的预编码信息比特是可变的，而控制信令中总预编码信息的比特是不可变的，从而可以降低终端接收控制信令的盲检复杂度。例如：如果网络侧设备所调度的调度资源大(例如：PRB数目多)，那么针对每个预编码颗粒采用较少比特指示预编码矩阵、如果网络侧设备所调度的调度资源小(例如：PRB数目少)，那么针对每个预编码颗粒采用较多比特数指示预编码矩阵，以保持总的预编码指示的控制信令大小不变。
在一些可选的实施例中，所述终端根据所述预编码颗粒的数目在所述N比特的预编码信息中确定每个预编码颗粒的预编码信息比特，包括：
终端根据所述预编码颗粒的数目，确定每个预编码颗粒的预编码信息比特的比特数目，并按照所述比特数目在所述N比特的预编码信息中确定每个预编码颗粒的预编码信息比特，其中，所述M为所述调度资源包括的预编码颗粒的数目。
该实施方式中，可以实现将预编码颗粒的预编码信息比特的比特数目是随调度资源的预编码颗粒的数目变化的，例如：如果网络侧设备所调度的调度资源大(例如：PRB数目多)，那么针对每个预编码颗粒采用较少比特指示预编码矩阵、如果网络侧设备所调度的调度资源小(例如：PRB数目少)，那么针对每个预编码颗粒采用较多比特数指示预编码矩阵，以保持总的预编码指示的控制信令大小不变。
另外，上述根据所述预编码颗粒的数目，确定每个预编码颗粒的预编码信息比特的比特数目可以是，根据预先获取的预编码颗粒的数目和预编码信息比特的比特数目的对应关系，确定每个预编码颗粒的预编码信息比特的比特数目。或者可以是将N与M进行运算，例如：将N除了M的整数作为每个预编码颗粒的预编码信息比特的比特数目，其中，M为所述预编码颗粒的数目，即上述调度资源的预编码颗粒的数目。例如：上述N为20，上述M为4，则每个预编码颗粒的预编码矩阵采用5个比特指示预编码矩阵索引。例如：如表1所示：
表1：
预编码信息比特 预编码矩阵索引
00000 预编码矩阵1
00001 预编码矩阵2
00010 预编码矩阵3
00011 预编码矩阵4
... ...
11111 预编码矩阵32
这样每个预编码颗粒通过5比特可以指示32个预编码矩阵中的一个预编码矩阵。
又例如：上述N为20，上述M为5，则每个预编码颗粒的预编码矩阵采用4个比特指示预编码矩阵索引。例如：如表2所示：
表2：
预编码信息比特 预编码矩阵索引
0000 预编码矩阵1
0001 预编码矩阵2
0010 预编码矩阵3
0011 预编码矩阵4
... ...
1111 预编码矩阵16
这样每个预编码颗粒通:4比特可以指示16个预编码矩阵中的一个预编码矩阵。
又例如：上述N为20，上述M为6，则每个预编码颗粒的预编码矩阵采用3个比特指示预编码矩阵索引。例如：如表3所示：
表3：
预编码信息比特 预编码矩阵索引
000 预编码矩阵1
001 预编码矩阵2
010 预编码矩阵3
011 预编码矩阵4
... ...
111 预编码矩阵8
其中，本公开实施例中可以将上述N比特中所述N除以M得的余数对应的比特采用预设值填充或者作为备用比特。例如：在表2所示的3比特的预编码信息，则20除3，余数为2，即20-(6*3)＝2，则将这2比特采用预 设值填充或者作为备用比特。
在一些可选的实施例中，所述终端获取每个预编码颗粒的预编码矩阵，包括：所述终端在每个预编码颗粒对应的预编码矩阵组中，选择各自的预编码信息比特指示的预编码矩阵。

该实施方式中，可以在每个预编码颗粒对应的预编码矩阵组不同，或者部分预编码颗粒对应的预编码矩阵组相同的情况下，每个预编码颗粒对应的预编码矩阵组采用预先获取的信令通知或者预先约定。而对于每个预编码颗粒对应的预编码矩阵组相同，即只有相同的一个预编码矩阵组，那么，该情况下可以不需要信令通知，该情况，以及该预编码矩阵组可以采用默认或者预先约定。另外，上述信令可以是步骤201接收到的控制信令，或者可以是其他信令，对此本公开实施例不作限定。
在一些可选的实施例中，所述终端根据调度资源确定预编码颗粒的数目，包括：所述终端根据所述控制信令中的所述调度资源的大小信息，确定预编码颗粒的数目；或者所述终端根据预先接收的其他信令指示的预编码颗粒的大小和所述调度资源的大小，确定的预编码颗粒的数目。
该实施方式中，可以实现根据控制信令中的调度资源的大小信息确定对应的预编码颗粒的数目，例如：可以根据预先获取的调度资源的大小信息与预编码颗粒的数目的对应关系，确定预编码颗粒的数目。这样由于预编码颗 粒的数目是由控制信令中的调度资源的大小信息确定的，以提高系统的灵活性。其中，上述调度资源的大小信息还可以称作调度资源大小信息。
另外，该实施方式中，还可以实现根据预编码颗粒的大小和所述调度资源的大小确定的预编码颗粒的数目，例如：将所述调度资源的大小与预编码颗粒的大小作运算，得到预编码颗粒的数目，如将调度资源的大小除以预编码颗粒的大小的整数作为预编码颗粒的数目；或者还可以实现根据预先获取的预编码颗粒的大小、所述调度资源的大小和预编码颗粒的数目这三者的对应关系，确定预编码颗粒的数目，以实现灵活向终端指示预编码颗粒的数目。
在一些可选的实施例中，每个预编码颗粒包括的子带采用相同的预编码矩阵，且每个预编码颗粒包括的子带个数为信令指示或预设数值。
其中，上述信令可以是步骤201接收到的控制信令，或者其他信令，对此本公开实施例不作限定。通过信令指示每个预编码颗粒包括的子带个数可以提高系统的灵活性，而采用预设数值可以减少传输开销。且每个预编码颗粒包括的子带个数可以相同或者不同的，另外，每个预编码颗粒包括具体子带可以为信令指示或者预先约定。
需要说明的是，本公开实施例介绍的多种可选的实施方式，彼此可以相互结合实现，也可以单独实现，对此本公开实施例不作限定。
