Description

传输方法、设备和传输系统、及存储介质
本申请基于申请号为201610323351.5、申请日为2016年05月13日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及无线通信技术，尤其涉及一种传输方法、设备和传输系统、及存储介质。
背景技术
随着移动通信技术的发展，第五代移动通信技术(5G，5-Generation)将支持更高速率(Gbps)、巨量链接(1M/Km2)、超低时延(1ms)、更高的可靠性、百倍的能量效率提升等以支撑新的数据流量的需求变化。其中，超低时延作为5G技术的关键指标，直接影响着如车联网、工业自动化、远程控制、智能电网等时延受限业务的发展。
增强半静态调度(SPS，Semi－Persistent Scheduling)是降低上行时延的一个重要研究方向，与现有的SPS技术相比，增强SPS引入更短的传输周期，比如1个传输时间间隔(TTI，Transmission Time Interval)，使得用户设备(UE，User Equipment)的上行时延大大降低，并且，当UE没有数据时，允许UE不传输任何内容，节省功耗并降低小区间的干扰。
但是，随着增强SPS中传输周期的降低，会导致重传和新传时发生碰撞的概率加大，因此，如何指示重传和新传是一个有待解决的问题。而且，根据现有的SPS技术，空包是通过MAC CE指示的，但如果演进型基站(eNB，evolved Node B)不能解码空包，那么UE就需要重传空包，可选地如果此时UE又恰好有新数据传输，则会延迟新数据的传输，增加数据的 传输时延。因此，如何识别空包和数据包也是一个有待解决的问题。对于上述两个问题，目前还没有有效的解决方案。
发明内容
本发明实施例期望提供一种传输方法、设备和传输系统、及计算机存储接介质，以解决重传和新传的碰撞概率高的问题，和/或传输时延大的问题。
本发明的技术方案是这样实现的：
第一方面，本发明实施例提供了一种传输方法，所述方法包括：
传输设备获取调度授权信息，其中，所述调度授权信息用于调度所述传输设备在至少一个传输时间间隔TTI上传输；
所述传输设备根据待传输数据的类型，按照预设的传输策略在所述至少一个传输时间间隔TTI上传输目标信号。
第二方面，本发明实施例提供了一种传输方法，所述方法包括：
接收设备接收传输设备根据调度授权信息传输的目标信号；
所述接收设备根据所述目标信号的接收方式识别所述目标信号的类型。

所述传输模块，配置为根据待传输数据的类型，按照预设的传输策略在所述至少一个传输时间间隔TTI上传输目标信号。
第四方面，本发明实施例提供了一种接收设备，所述接收设备包括： 接收模块和识别模块；其中，
所述接收模块，配置为接收传输设备根据调度授权信息传输的目标信号；
所述识别模块，配置为根据所述目标信号的接收方式识别所述目标信号的类型。

所述传输设备，配置为获取调度授权信息；
以及，根据待传输数据的类型，按照预设的传输策略在所述调度授权信息中的至少一个传输时间间隔TTI上传输目标信号；
所述接收设备，配置为接收所述传输设备传输的目标信号，并根据所述目标信号的接收方式识别所述目标信号的类型。
第六方面，本发明实施例提供一种通信设备，包括：
存储器，配置为存储计算机程序；
通信接口，用于与其他设备进行信息传输；
处理器，分别于所述存储器及所述通信接口连接，配置为通过执行所述计算机程序，能够实现前述任意一个或多个技术方案提供的传输方法。
第七方面，本发明实施例提供一种计算机存储介质，配置为存储计算机程序；所述计算机程序被处理器执行后能够实现前述任意一个或多个技术方案提供的传输方法。
本发明实施例提供了一种传输方法、设备和传输系统、及计算机存储介质，根据待传输数据的类型，采用预设的传输策略传输目标信号；当待传输的数据的类型分为新传的新传数据或重传的重传数据时，可以根据预设传输策略采用不同的传输方式，从而减少新传和重传的碰撞概率。当待 传输的数据的类型分为空包和非空包时，同样可以根据预设传输策略采用不同的传输方式，从而显然本发明实施例提供的技术方案可以用于解决SPS中的碰撞的概率高及传输时延大大的问题。，故用于增强SPS中传输周期降低时，具有重传和新传时发生碰撞的概率低，并且能够有效地区分数据包类型的特点。

示例性地，当新传数据包和重传数据包的传输时间对应相同的TTI时，所述接收设备根据所述目标信号的接收方式识别所述目标信号的类型，可包括：

或者，所述接收设备按照预设的优先级确定所述目标信号为新传数据包或重传数据包。
可选地，所述接收设备按照预设的优先级确定所述目标信号为新传数据包或重传数据包，可包括：
所述接收设备首先接收到的数据包为重传数据包。
示例性地，当新传数据包和重传数据包的传输时间对应相同的TTI时，且所述重传数据包对应的首传数据包为空包或者DTX时，所述接收设备根据所述目标信号的接收方式识别所述目标信号的类型，可包括：所述接收设备将接收到的目标信号确定为新传数据包。
本实施例提供了一种传输方法，接收设备在接收过程中，根据目标信号的不同接收方式来确定目标信号的类型，从而当增强SPS中传输周期降低时，能够减少重传和新传时发生碰撞的概率，并且能够有效地区分目标信号类型是空包或者数据包。
基于前述实施例相同的技术构思，本发明实施例通过示例对上述实施例的技术方案进行说明，在以下示例中，接收设备均设定为eNB，传输设备均设定为UE；示例如下：
示例一
本示例用于说明UE传输空包或者数据包的具体方法，需要说明的是，当没有数据要传输，即UE的缓存为空时，会传输空包。空包的具体形式本发明实施例中不作具体的局限。而且本发明实施例中以上行传输为例来说明，可以理解地，该技术方案也能够用于上行和/或下行。
可选地，UE可以根据DMRS的不同来指示空包和数据包，具体可以 包括但不限于以下几种方式：
1、UE通过DMRS占用的符号位置来指示。
比如，UE在eNB分配的资源上传输，如果DMRS在每个时隙的符号#3上传输，则表示UE传输的是数据包；如果DMRS在每个时隙的符号#4上传输，则表示UE传输的是空包。
相应地，eNB可以通过UE传输的DMRS的符号位置来确定UE传输的是数据包还是空包。该方式可以不限于应用在现有LTE的场景，比如也可以用于短TTI场景，即TTI的长度小于14个符号。
2、UE通过DMRS采用的序列来指示。
比如，eNB给UE分配两个DMRS序列，序列#1和序列#2。UE在eNB分配的资源上传输，如果UE传输的DMRS采用序列#1，则表示传输的是数据包；如果UE传输的DMRS采用序列#2，则表示传输的是空包。
相应地，eNB可以通过UE传输的DMRS采用的序列来确定UE传输的是数据包还是空包。
在确定一个数据包是否为空包时，可以由基站，例如(eNB)给UE分配DMRS序列的两种循环移位方式，如果UE传输的DMRS采用第一种循环移位方式形成的，则表示传输的是非空数据包；如果UE传输的DMRS采用第二种循环移位方式形成的，则表示传输的是空包。
3、UE通过DMRS占用的频域资源来指示。
比如，UE在eNB分配的资源上传输，如果DMRS占用所述DMRS符号上的奇数子载波，则表示UE传输的是数据包；如果DMRS占用所述DMRS符号上的偶数子载波，则表示UE传输的是空包。
相应地，eNB可以通过UE传输的DMRS占用的频域位置来确定UE 传输的是数据包还是空包。
需要说明的是，空包的MCS是预设的，或者是eNB指示的，可以与本次调度指示的MCS不同。
比如，本次调度eNB指示的MCS＝15，而空包采用MCS＝0，码率很低，采用这样的方式，可以使eNB正确解调空包，降低空包重传的概率。eNB在解码时，可以按照两种MCS进行尝试解码。
可选地，UE可以根据占用的资源的不同来指示空包和数据包，具体可以包括但不限于以下几种方式：
1、UE根据占用的频域资源来指示。
比如，如果UE在eNB分配的资源上传输，则表示传输的是数据包；如果UE在预设的频域资源上传输，则表示传输的是空包，所述预设的频域资源可以是所述分配的频域资源中的部分频域资源。比如，如果eNB分配的资源为PRB#0～9，当传输的是空包时，则所述空包在一半频域资源上传输，比如为最低的一半频域资源，即PRB#0～4，或者在起始PRB上传输，即PRB#0。
2、UE根据占用的时域资源来指示。
比如，如果UE在eNB分配的资源上传输，则表示传输的是数据包；如果UE在预设的时域资源上传输，则表示传输的是空包，所述预设的时域资源可以是所述分配的时域资源中的部分时域资源。比如，eNB调度UE在子帧#n上传输，如果传输的是空包，则所述空包在子帧#n的第一个时隙上传输，或者，在第二个时隙上传输，或者，在某个符号上传输，比如第一个符号。
3、UE根据占用的时频资源来指示。
比如，如果UE在eNB分配的资源上传输，则表示传输的是数据包； 如果UE在预设的时频资源上传输，则表示传输的是空包，所述预设的时频资源可以是所述分配的时频资源中的部分时频资源。比如，eNB调度UE在子帧#n上的PRB#0～9传输，如果传输的是空包，则所述空包在子帧#n的第一个时隙上的PRB#0～9传输。
需要说明的是，所述空包的MCS是预设的，或者是eNB指示的，可以与本次调度指示的MCS不同。比如，本次调度eNB指示的MCS＝15，而空包采用MCS＝0，码率很低，采用这样的方式，可以使eNB正确解调空包，降低空包重传的概率。eNB在解码时，按照两种MCS进行尝试解码。
可选地，UE可以采用上述方式的混合来指示空包和数据包，具体可以包括但不限于以下几种方式：
1、当eNB发送了SPS上行授权，对于第一次传输，UE即可以采用上述的方式传输。这样，eNB可以获知UE收到了SPS上行授权。
2、如果UE在之前的传输中传输的是空包或者没有传输数据，而eNB反馈NACK和/或调度了重传，则UE可以采用上述的方式传输空包。
3、在SPS传输中，UE可以以指定周期在指定TTI在SPS资源上传输信号，所述指定周期和SPS传输周期不同，比如可以大于SPS传输周期。比如SPS的周期可以是1个TTI，所述传输信号的周期可以是10个TTI。在指定TTI上，如果UE有数据要传输，则按照上述方式传输数据包；如果没有数据传输，则按照上述方式传输空包。eNB可以根据所述信号进行上行信道的测量。
示例二
本示例用于说明UE指示是否有数据进行传输的实现方式，可以包括：
1、当UE收到eNB发送的上行授权，如果UE有数据传输，则会传输数据包，如果UE没有数据传输，则可以传输预设的指示信号来指示UE此 时没有数据。
2、当UE没有数据要传输时，UE可以只传输DMRS，即在传输DMRS的位置上传输DMRS，其余符号上不传输任何信号。
比如，UE只在一个子帧上的两个时隙上的第四个符号上传输DMRS，其余符号上不传输任何信号。
3、当UE没有数据要传输时，UE可以在部分或者所有符号上传输DMRS。
比如，UE在所有符号上重复传输DMRS。
4、当UE没有数据要传输时，UE传输指定信号。比如为预定义的信号。
5、eNB给UE分配一个PUCCH资源，当UE没有数据要传输时，UE在该资源上传输信号。当UE有数据要传输时，则在eNB分配的资源上传输数据，在该PUCCH资源上不传输任何信号。
6、在SPS传输中，UE可以以指定周期在指定TTI在SPS资源上传输信号，所述指定周期和SPS传输周期不同，比如可以大于SPS传输周期。eNB可以根据所述信号进行上行信道的测量。
示例三
本示例用于说明UE指示其传输的数据包是新传数据包还是重传数据包的具体实现方法，可以包括：
1、UE在物理上行共享信道(PUSCH，Physical Uplink Shared Channel)中传输以下信息的至少之一：新传数据包或者重传数据包的指示信息以及冗余版本(RV，Redundancy Version)。
比如新传或者重传的指示信息为1bit，RV的指示信息为2bit，分别指示冗余版本0、2、3、1。比如，用“0”表示重传，“1”表示新传；或者， 通过该指示信息是否翻转来指示是新传还是重传。
可选地，，所述新传或者重传的指示信息以及RV中的至少之一采用独立编码。所述新传或者重传的指示信息以及RV中的至少之一和数据级联，并进行传输。或者，所述新传或者重传的指示信息以及RV中的至少之一在预设的符号上传输，比如在第一个符号中传输，比如从交织矩阵的最后一行向上开始映射。
2、UE采用不同的C-RNTI来加扰数据，指示以下信息的至少之一：新传数据包或者重传数据包的指示信息以及RV。
在现有技术中，假设码字q上传输的比特为
Figure PCTCN2017084246-appb-000001
采用序列c(q)(i)进行加扰，即
Figure PCTCN2017084246-appb-000002
其中c(q)(i)采用UE的C-RNTI进行初始化，即
Figure PCTCN2017084246-appb-000003
假设给UE分配了两个C-RNTI，即nRNTI_1和nRNTI_2。其中，当数据为新传时，c(q)(i)采用nRNTI_1进行初始化，当数据为重传时，c(q)(i)采用nRNTI_2进行初始化。或者，给UE分配了四个C-RNTI，分别用于指示四个RV。
可选地，采用UE的C-RNTI或者SPS-RNTI加扰数据来指示上述信息。比如，采用UE的C-RNTI加扰新传数据，采用SPS-RNTI加扰重传数据。
3、UE采用不同的C-RNTI来加扰数据的CRC，指示以下信息的至少之一：新传数据包或者重传数据包的指示信息以及RV。
在现有技术中，数据的CRC长度为24bit，可以采用不同的C-RNTI和CRC的预设的16bit做异或，比如与最低位的16bit做异或。或者，采用不同的C-RNTI初始化生成序列，类似方式二中的方式，去所述生成序列的预设的24个bit和CRC做异或，比如用起始的24个bit。
可选地，采用UE的C-RNTI或者SPS-RNTI加扰数据的CRC来指示上述信息。
4、UE采用DMRS来指示以下信息的至少之一：新传数据包或者重传数据包的指示信息以及RV。
类似于示例一，通过DMRS采用的时域位置、序列和频域位置中的至少之一来指示。
5、UE采用以上方法的混合。
需要说明的是，本示例中的实现方法不限于应用在SPS传输中，也可以用于其它场景。
示例四
本示例用于说明在SPS传输中，如果UE的重传和新传发生在相同TTI时，而重传的资源和新传的资源不相同时，UE采用的处理方式，需要说明的是，重传可以是eNB调度的，或者重传的资源可以是eNB配置的，比如通过RRC信令通知的，或者，也可以是预设的，比如为和SPS分配的资源相邻的资源。UE采用的方式可以包括：
1、UE同时传输重传数据包和新传数据包。
比如，SPS分配的资源为PRB#0～9，重传分配的资源为PRB#20～29，那么UE在PRB#0～9和PRB#20～29上同时传输。可选地，为了保证UE传输信号的单载波特性，eNB可以将重传的资源和SPS资源配置成在频域上连续的，比如SPS分配的资源为PRB#0～9，重传分配的资源为PRB#10～19.可选地，重传的资源可以和SPS分配的资源不相等，比如SPS分配的资源为10个PRB，重传的资源为20个PRB。
2、UE定义传输的优先级。
比如UE优先传输重传数据包。在SPS分配的资源上可以不传输任何信号，即放弃传输新传数据包，或者推迟传输新传数据包。
3、如果UE在之前的传输中传输的是空包或者没有传输数据，这里没 有传输数据可以称为DTX，而eNB反馈NACK和/或调度了重传，如果重传数据包和UE传输的新传数据包对应相同的TTI时，UE在SPS分配的资源上传输新传，在重传的资源上不传输任何信号。
需要说明的是，本示例中的实现方法不限于应用在SPS传输中，也可以用于其它场景。
