Description

上行传输方法及装置 技术领域
本公开涉及通信领域，尤其涉及上行传输方法及装置。
背景技术
对于LTE(Long Term Evolution，长期演进)的系统中，终端的上下行传输是基于基站的调度进行的。对于动态的调度来讲，一个调度信令只能指示一个时间单元上的数据传输，如图1A所示。
但是针对工作在非授权频谱的终端而言，终端在需要占用信道时，首先要监听信道是否空闲。当所述信道处于空闲状态时，终端才能占用所述信道。在现有技术中，终端进行上行传输的起始位置是基于调度信令进行指示的或是由基站为所述终端预先配置的，然而由于非授权频谱上信道占用的不确定性，上行数据传输的起始位置也是不确定的。
为了解决这一问题，终端可以在监听到信道处于空闲状态时才开始进行上行数据的传输。例如图1B所示，终端在信道处于空闲状态的时间单元上传输上行数据。但是采用这种方法，一旦终端监听到信道处于空闲状态所对应的时间单元的数目较少，会导致传输的数据在基站侧无法解码，造成传输资源的浪费。
可选地，终端还可以针对每一个可能的传输上行数据的起始位置，都通过相应的调度指令指示数据包的调度信息，如图1C所示。调度信令1对应指示终端传输上行数据的起始位置为时间单元0时的调度信息，调度信令2则对应指示终端传输上行数据的起始位置为时间单元1时的调度信息，以此类推。但是采用这种方式，基站需要传输多个调度指令，同样会造成资源的浪费。

下面先从非授权频谱中的终端侧介绍本公开实施例提供的上行传输方法。
本公开实施例提供了一种上行传输方法，可以用于非授权频谱中的终端。参照图2所示，图2是根据一示例性实施例示出的一种上行传输方法流程图，可以包括以下步骤：
在步骤101中，确定目标指示参数；所述目标指示参数用于指示所述终端传输上行数据时应采用的目标传输方式；
在步骤102中，根据所述目标指示参数，确定所述目标传输方式；
在步骤103中，基于所述目标传输方式，传输上行数据到非授权频谱中的基站。
上述实施例中，非授权频谱中的终端可以先确定目标指示参数，进一步地，终端根据所述目标指示参数来确定传输上行数据时应采用的目标传输方式，基于该目标传输方式，传输上行数据到非授权频谱中的基站。通过上述过程，可以通过目标指示参数指示终端传输上行数据时应采用的目标传输方式，解决了非授权频谱中信道占用的不确定性所导致的资源浪费的问题。
针对上述步骤101，终端可以采用以下方式中的任意一种来确定目标指示参数的目标数值：
第一种方式，获取协议中预先定义的所述目标指示参数。
此种方式下，可以预先在协议中规定目标指示参数的数值，终端直接获取所述目标指示参数的数值即可。
第二种方式，接收所述基站通过预设信令发送的所述目标指示参数。
可选地，所述预设信令可以是RRC(Radio Resource Control，无线资源控制)信令、MAC(Media Access Control，媒体访问控制)CE(Control Element，控制单元)或物理层信令，例如调度信令。
此种方式下，基站可以为终端配置所述目标指示参数的数值，并通过所述预设信令将所述目标指示参数的数值发送给终端。
可选地，基站还可以在调度信令中预先设置一个与目标指示参数对应的信息域，终端读取该信息域的数值并将读取的数值作为目标指示参数的数值。
上述两种方式中，终端可以直接获取目标指示参数的数值，在本公开实施例中，可选地，终端还可以通过如下的间接方式来获取所述目标指示参数的数值。
第三种方式，参照3所示，图3是根据图2所示的实施例示出的另一种上行传输方法流程图，上述步骤101可以包括以下步骤：
在步骤101-1中，接收所述基站通过调度信令发送的用于指示目标调制编码方式的指示信息；
其中，所述目标调制编码方式是所述终端传输上行数据时应采用的调制编码方式。
本步骤中，基站可以通过调度信令指示所述终端传输上行数据时应采用的目标调制编码方式。
在步骤101-2中，根据预先确定的多种调制编码方式和所述目标指示参数的多个备选数值之间一一对应的映射关系，确定与所述目标调制编码方式对应的所述目标指示参数的数值。
本公开实施例中，可选地，基站可以预先通过RRC信令、MAC CE或物理层信令将所述映射关系发送给终端，或者可以在协议中预先定义该映射关系，所述预设关系可以如表1所示。
表1
调制编码方式 备选数值
调制编码方式1 X 1
调制编码方式2 X 2
…… ……
调制编码方式N X N
终端在确定了所述目标调制编码方式之后，可以根据表1查找与所述目标调制编码方式对应的备选数值，则该备选数值即为目标指示参数的数值。
例如，目标调制编码方式为调制编码方式2，则X 2即为目标指示参数的数值。
在本公开实施例中，终端可以采用上述任一种方式来确定目标指示参数的数值。可选地，所述目标指示参数的数值可以是固定值，或者是可变的值，由基站随时根据信道状况来调整。或者可以由协议或基站指定所 述目标指示参数的数值所属的范围值，例如范围值为(0,1)，再由基站根据信道状况在上述范围值内指定目标指示参数的具体数值。
针对上述步骤102，参照4所示，图4是根据图2所示的实施例示出的另一种上行传输方法流程图，上述步骤102可以包括以下步骤：
在步骤102-1中，对需要使用的信道进行信道监听，在所述终端所对应的时域资源中确定目标时间单元所在的位置；
本步骤中，基站可以预先为终端配置好对应的传输上行数据的时域资源，终端在需要进行上行传输时，可以先对需要使用的信道进行信道监听，确定所述信道处于空闲状态的起始时间单元，即确定目标时间单元所在的位置。
在步骤102-2中，计算第一时间单元的总数目占所述时域资源所包括的所有时间单元的总数目的百分比；
例如图5所示，基站预先分配给终端的传输上行数据的时域资源包括14个时间单元，目标时间单元所在的位置在第6个时间单元，第一时间单元的总数目为5个，则所述百分比为0.36。
在步骤102-3中，如果所述百分比小于或等于所述目标指示参数的数值，则确定所述目标传输方式为第一传输方式，否则确定所述目标传输方式为第二传输方式。
本步骤中，假设目标指示参数的数值为0.5，如果上述步骤102-2中计算出的所述百分比小于或等于所述目标数值，此时可以确定所述目标传输方式为第一传输方式，如果所述百分比大于所述目标数值，则可以确定所述目标传输方式为第二传输方式。
针对上述步骤103，在本公开实施例中，如果确定目标传输方式为第一传输方式，则步骤103可以具体为从所述目标时间单元开始传输上行数据到所述基站。
例如图6所示，此时第一时间单元的总数目较少，终端可以占用的时间单元的数目较多，因此，终端可以从目标时间单元开始通过所述信道 将上行数据传输给基站。避免基站无法解调上行数据导致资源浪费的问题。
如果终端确定目标传输方式为第二传输方式，则参照7所示，图7是根据图4所示的实施例示出的另一种上行传输方法流程图，上述步骤103可以包括以下步骤：
在步骤103-1中，在预设数目的备选数据包中选取至少一个作为目标数据包；每个所述备选数据包的传输分别占用预设的时间单元数目；
本步骤中，如果预设数目为1个，则终端直接将该备选数据包作为目标数据包即可。
如果预设数目为多个，则终端需要选取目标数目的所述备选数据包作为所述目标数据包。
例如预设数目为3个，数据包1的传输需要占用2个时间单元，数据包2的传输需要占用2个时间单元，数据包3的传输需要占用3个时间单元，第二时间单元的总数目为7，则可以确定目标数目为3，即所有备选数据包均可以作为目标数据包。
如果第二时间单元的总数目为5，则可以将数据包1和数据包3作为目标数据包，或者将数据包2和数据包3作为目标数据包。
在步骤103-2中，从所述目标时间单元之后的第一个时间单元开始，按照预设的数据包传输顺序，将所述上行数据通过所述目标数据包进行承载之后，传输所述目标数据包到所述基站。
本公开实施例中，可选地，可以在协议中预先定义数据包传输顺序，或者由基站通过调度信令告知所述终端所述数据包传输顺序。另外，可以由基站预先通过至少一个调度信令将每个备选数据包对应的调度信息发送给所述终端。
本步骤中，终端在选取出了目标数据包之后，也同时确定了每个目标数据包的传输所占用的时间单元数目，此时终端可以按照相关技术，按照预设的所述数据包传输顺序，从所述目标时间单元之后的第一个时间单元开始，通过目标数据包承载上行数据，并发送所述目标数据到所述基站。
通过上述过程，基站无需针对每个可能的上行数据起始位置配置多个调度信令，节省了调度信令的资源，且可以在第一时间单元较多，即终端可以占用的时间单元较少时，通过传输占用预设的时间单元数目的目标数据包承载上行数据，从而可以避免传输的上行数据在基站侧无法解码的问题，同样避免了资源浪费。
对上述步骤103进一步举例说明。
例子1，基站预先分配给终端的传输上行数据的时域资源包括14个时间单元，第一时间单元的总数目为5，则百分比0.36，目标数值为0.5，此时终端可以采用图6所示的方式将上行数据发送给基站。
例子2，基站预先分配给终端的传输上行数据的时域资源包括14个时间单元，第一时间单元的总数目为8个，则百分比0.57，目标数值为0.5，此时需要采用第二传输方式传输上行数据。
假设预设数目为1，备选数据包为数据包1，且备选数据包的传输占用2个时间单元。则终端将数据包1作为目标数据包，通过占用2个时间单元的数据包1来承载上行数据，如图8A所示。
例子3，基站预先分配给终端的传输上行数据的时域资源包括14个时间单元，第一时间单元的总数目为8个，则百分比0.57，目标数值为0.5，此时需要采用第二传输方式传输上行数据。
假设预设数目为3，其中，数据包1的传输需要占用2个时间单元，数据包2的传输需要占用2个时间单元，数据包3的传输需要占用3个时间单元，第二时间单元的总数目为5，则可以确定目标数目为2，即数据包1和数据包3可以作为目标数据包来承载上行数据，预设的数据包传输顺序为数据包1、数据包2和数据包3，则终端发送的目标数据包如图8B所示。
下面再从非授权频谱中的基站侧介绍本公开实施例提供的上行传输方法。
本公开实施例提供了另一种上行传输方法，可以用于非授权频谱中 的基站。参照9所示，图9是根据一实施例示出的另一种上行传输方法流程图，所述方法可以包括以下步骤：
在步骤201中，通过调度信令发送用于指示目标调制编码方式的指示信息给非授权频谱中的终端，由所述终端根据预先确定的多种调制编码方式和目标指示参数的多个备选数值之间一一对应的映射关系，确定与所述目标调制编码方式对应的所述目标指示参数的数值；
其中，所述目标调制编码方式是所述终端传输上行数据时应采用的调制编码方式；所述目标指示参数用于指示所述终端传输上行数据时应采用的目标传输方式；
在步骤202中，接收所述终端基于所述目标传输方式传输的上行数据。
上述实施例中，基站可以通过调度信令将指示信息发送给终端，所述指示信息指示了目标调制编码方式，终端可以根据所述映射关系，来确定所述目标指示参数的数值，进一步地，根据所述目标指示参数确定目标传输方式，基站接收所述终端基于所述目标传输方式传输的上行数据即可。通过上述过程，基站可以间接将目标指示参数告知终端，便于终端基于目标指示参数来确定目标传输方式，可用性高。
针对上述步骤201，基站可以通过调度信令将用于指示目标调制编码方式的指示信息发送给终端。之前基站已经预先通过RRC信令、MAC CE或物理层信令将表1发送给了所述终端，终端可以根据表1查找与所述目标调制编码方式对应的备选数值，从而确定所述目标指示参数的数值。
针对上述步骤202，终端在确定了目标指示参数的数值之后，可以确定目标传输方式，基站直接接收终端采用所述目标传输方式传输的上行数据即可。
在一实施例中，终端可以直接获取协议中预先定义的目标指示参数的数值，从而根据目标指示参数的数值来确定目标传输方式，基站直接接收终端基于所述目标传输方式传输的上行数据即可。
在一实施例中，通过预设信令发送目标指示参数给所述终端。
基站还可以通过所述预设信令将为所述终端配置的所述目标指示参数的数值发送给所述终端。其中，预设信令可以是RRC信令、MAC CE或者物理层信令，例如调度信令，
可选地，基站可以在调度信令中预先设置一个与所述目标指示参数对应的信息域，基站在发送调度信令时，可以将目标指示参数的数值通过所述信息域发送给所述终端。
由所述终端根据所述目标指示参数的数值按照上述步骤102至103的方式，确定目标传输方式之后，采用目标传输方式，传输上行数据到所述基站。
在一实施例中，参照10所示，图10是根据一实施例示出的另一种上行传输方法流程图，所述上行传输方法可以包括以下步骤：
在步骤301中，基站发送目标指示参数给所述终端。
可选地，基站可以通过预设信令或调度信令中与所述目标指示参数对应的信息域将所述目标指示参数发送给所述终端。
在步骤302中，终端对需要使用的信道进行信道监听，在所述终端所对应的传输上行数据的时域资源中确定目标时间单元所在的位置。
其中，所述目标时间单元是监听到所述信道处于空闲状态的起始时间单元。
在步骤303中，终端计算第一时间单元的总数目占所述时域资源所包括的所有时间单元的总数目的百分比。
在步骤304中，如果所述百分比小于或等于所述目标指示参数的数值，则确定所述目标传输方式为第一传输方式，否则确定所述目标传输方式为第二传输方式。
在步骤305中，如果所述目标传输方式为所述第一传输方式，终端从所述目标时间单元开始通过所述信道传输上行数据到所述基站。
在步骤306中，如果所述目标传输方式为所述第二传输方式，终端 在预设数目的备选数据包中选取至少一个作为目标数据包。
其中，每个所述备选数据包的传输占用预设的时间单元数目。
在步骤307中，从所述目标时间单元之后的第一个时间单元开始，按照预设的数据包传输顺序，将所述上行数据通过所述目标数据包进行承载之后，传输所述目标数据包到所述基站。
上述实施例中，终端在确定目标传输方式时，可以对需要使用的信道进行信道监听，在所述终端所对应的传输上行数据的时域资源中确定目标时间单元所在的位置。终端可以第一时间单元的总数目较少时，采用第一传输方式，直接从所述目标时间单元开始传输上行数据，从而避免资源浪费。还可以在第一时间单元的总数目较多时，采用第二传输方式，在预设数目的备选数据包中选取至少一个作为目标数据包。从所述目标时间单元之后的第一个时间单元开始，按照预设的数据包传输顺序，将所述上行数据通过所述目标数据包进行承载之后，传输所述目标数据包到所述基站。通过上述过程，可以将传输占用预设时间单元数目的备选数据包中的至少一个作为目标数据包来承载上行数据，从而避免第一时间单元较多时，传输的上行数据在基站侧无法解码的问题，避免资源浪费。
在上述实施例中，基站也可以预先通过预设信令将表1发送给终端，进一步地，基站再通过调度信令将目标调制编码方式发送给所述终端，终端可以根据基站发送的表1或预先定义在协议中的表1，查找与所述目标调制编码方式对应的数值作为目标指示参数的数值，进而执行上述步骤302至308。
