Description

一种上行传输的方法及基站
本申请要求于2016年8月5日提交中国专利局，申请号为201610639607.3、发明名称为“一种上行传输的方法及基站”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，尤其涉及一种上行传输的方法及基站。
背景技术
随着用户通信需求的快速提升，通信业务量呈现爆发式增长，长期演进（Long Term Evolution，LTE）以及增强的长期演进（Long Term Evolution-Advanced，LTE-A）的资源调度粒度以及处理时延已经不能充分满足用户的需求。具体地，在现有的4G以及4.5G移动通信技术中，都是基于LTE及LTE-A无线接入技术中的单位时间长度来进行。其单位时间长度的大小通常是固定，例如，在LTE技术中，单位时间长度通常为一个子帧，子帧的时间长度为1毫秒，因此，在LTE技术中，一个传输时间间隔（Transmission Time Interval，TTI）的时长也就是一个单位时间长度的时长即1毫秒。在现有技术中，基站进行上行调度时，上行发送UL grant（上行授权）信令和开始传输上行数据的时间间隔一般需要在4个TTI之后，即上行调度时延通常大于等于4毫秒。这样的调度时延无法满足未来5G业务的时延多样化需求。
在未来5G业务中可包括以下三种：增强的移动宽带（enhanced Mobile BroadBand，eMBB）业务，高可靠低时延（Ultra-Reliable and Low Latency Communications，URLLC)业务和大量机器类通信（massive Machine Type Communications，mMTC）业务。这三种业务的时延需求相差较大。例如，eMBB业务，两个主要的指标是高带宽和低时延，时延要求4ms。而对于URLLC业务，时延要求是0.5ms。而mMTC业务，需要的是窄带服务，需要电池寿命很长，这种业务就需要更小粒度的频域和更宽粒度的时域资源，因此时延要求相对较低。现有固定且数值较大的时延已经无法满足5G业务的需求。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明实施例中的通信系统可以包括基站以及终端。
本发明实施例中的用户设备也可以称之为终端，其可以包括智能手机（如Android手机、IOS手机、Windows Phone手机等）、平板电脑、掌上电脑、笔记本电脑、移动互联网设备（Mobile Internet Devices，MID）或穿戴式设备等，上述用户设备仅是举例，而非穷举，包含但不限于上述用户设备。
本发明实施例中的基站可以根据与终端之间进行的业务来配置单个传输时间间隔 (Transmission Time Interval, TTI)的时间长度以及与业务类型对应的时延修正值k，并通过上行授权信令将相关的配置信息发送给终端，终端在收到这些信息之后，便可以根据这些信息进行上行数据的传输。下面具体结合图1-图3进行说明。
请参照图1，为本发明上行传输的方法的第一实施例的流程示意图，在本实施例中，所述方法包括以下步骤：
S101，基站根据传输的业务类型确定单个传输时间间隔t的时长以及与所述业务类型对应的时延修正值k。
传输的业务类型可以包括但不限于使用授权频谱的LTE业务、使用非授权频谱的LTE业务、eMBB业务、URLLC业务和mMTC业务。每种业务对时延的要求都有所不同。
其中，t=2n*5m毫秒，m和n为整数，k为大于等于-4的整数。
此处的m和n可以是正整数也可以负整数，还可以是0。可选地，基站可以针对不同业务确定使用不同时间长度的TTI。例如，可以确定m为0，n可以等于-3、-2、-1，也可以等于1、2、3，还可以等于0，这样，TTI的时间长度则依次可以为0.125ms，0.25ms、0.5ms、2ms、4ms、8ms或1ms。或者，可以确定n为0，m可以等于-3、-2、-1，也可以等于1、2、3，还可以等于0，这样，TTI的时间长度则依次为0.008ms、0.04ms、0.2ms、5ms、25ms、125ms或1ms。当然，m和n可以都不为0，如m为-1，n为2，则TTI的时间长度为0.8ms，根据不同的业务需求基站可以进行自适应调整m和n的值来适应业务需求，本发明实施例不作任何限定。
而时延修正值，可用于修正TTI的个数，其可以为正整数，0或大于等于-4的负整数。例如，参照LTE频分双工系统，若基站发送上行授权信令之后，终端需要经历4个TTI之后发送上行数据，则可将上行调度时延视为4个TTI，在本实施例中，通过引入时延修正值k，可以根据业务类型对TTI的个数进行调整。当k为正数时，上行调度时延将大于4个TTI；当k为0时，则上行调度时延仍然为4个TTI；当k为负数时，则上行调度时延小于4个TTI。
当确定了t和k之后，便可以根据如下公式计算上行调度时延T：
T=（4+k）*t
例如，上行授权信令在n时刻发出，则第一次发送上行数据的时间为n+（4+k）*t。由于不同的业务类型对时延的要求不同，因此k和t的取值也不同。
可选地，若所述业务类型为使用授权频谱的长期演进LTE业务，则第一上行调度时延T1=（4+k）*t，其中，t等于1毫秒，k大于等于0；当为频分双工（Frequency Division Duplex，FDD）系统时，k=0；当为时分双工(Time Division Duplexing，TDD)系统时，k可以大于0。
若所述业务类型为使用非授权频谱的LTE业务，则第二上行调度时延T2=（4+k）*t，其中，t等于1毫秒，k大于等于0且小于等于7；
若所述业务类型为增强的移动宽带eMBB业务，则第三上行调度时延T3=（4+k）*t，其中，t小于等于1毫秒，k小于等于0；
若所述业务类型为高可靠低时延URLLC业务，则第四上行调度时延T4=（4+k）*t，其中，t小于1毫秒，k小于等于0，且T4小于T3；
若所述业务类型为大量机器类通信mMTC业务，则第五上行调度时延T5=（4+k）*t，其中，t大于等于2毫秒，k大于等于0。
上行调度时延T可以计算得到具体结果，也可以不计算具体结果，如果计算具体结果，可以由基站计算也可以由终端接收到k、t的值之后计算，本发明实施例不做任何限定。
S102，向终端发送上行授权信令，在所述上行授权指令中指示上行数据的上行传输信息。
可选地，所述上行传输信息包括第一次发送上行数据的时间和发送上行数据的时间个数，或者所述上行传输信息包括第一次发送上行数据的时间、发送上行数据的时间个数以及每两次发送上行数据的时间的间隔。
可选地，一个UL grant信令可以调度一个或一个以上上行发送的时间，因此，需要在上行授权信令中指示第一次发送上行数据的时间以及发送上行数据的时间个数N。而且，当存在一个以上上行发送的时间时，由于这些时间可以是连续的也可以是非连续的，因此还需要根据情况来确定是否需要指示每两次发送上行数据的时间的间隔。每两次发送上行数据的时间的间隔可以相同，也可以不同，当相同的时候则类似于周期性传输上行数据。
例如，在LTE授权频谱中N为1；又例如LTE非授权频谱中N可以为1，也可以为2~4，当为2~4时，是多个连续的发送时间间隔；又比如mMTC业务中，N也可以大于等于3，每两次之间时间间隔可以一样，就像是周期性的上行发送（如上报水表数）。
S103，将所述单个传输时间间隔t的时长信息、所述时延修正值k的信息和所述上行传输信息通知所述终端。
可选地，通知的方式可以包括但不限于：使用现有的信令携带相关信息并发送给终端、构建相关信息的映射表格通过映射的方式通知终端等。
S104，接收所述终端根据所述单个传输时间间隔t的时长信息、所述时延修正值k的信息和所述上行传输信息传输的上行数据，完成上行传输。
当终端获取到上述信息之后，便可以知道何时发送上行数据，顺利与基站完成上行传输。
在本实施例中，基站可以根据传输的业务类型确定了单个传输时间间隔t的时长以及与所述业务类型对应的时延修正值k，并且在上行授权信令中携带发送上行数据相关的传输信息，然后将这些参数和信息通知终端；终端便可以根据这些参数和信息确定传输上行数据的时间和方式，由于单个传输时间间隔t的值和时延修正值k根据业务类型确定，因此，可以充分满足不同业务的时延需求，尤其对于未来5G业务中一些时延要求较高的业务，可通过配置合适的t值和k值来适应业务需求，提高了系统的灵活性，同时也提升了用户的数据传输体验。
请参照图2，为本发明上行传输的方法的第二实施例的流程示意图，在本实施例中，所述方法包括以下步骤：
S201，基站根据传输的业务类型确定单个传输时间间隔t的时长以及与所述业务类型对应的时延修正值k。
其中， t=2n*5m毫秒，m和n为整数，k为大于等于-4的整数。
S202，确定发送上行数据的时间个数。
S203，当发送上行数据的时间个数多于一个时，判断发送上行数据是否为占用连续多个发送时间。若是，则执行步骤S204，否则执行步骤S205。
可选地，若发送上行数据的时间个数为一个，则在所述上行授权信令中携带发送上行数据的时间和发送上行数据的时间个数，将所述上行授权信令发送给所述终端。
S204，在所述上行授权信令中携带第一次发送上行数据的时间和发送上行数据的时间个数，将所述上行授权信令发送给所述终端。
在步骤S204之后，执行步骤S206-S207。
S205，在所述上行授权信令中携带第一次发送上行数据的时间、发送上行数据的时间个数以及每两次发送上行数据的时间的间隔，将所述上行授权信令发送给所述终端。
在步骤S205之后，执行步骤S206-S207。
S206，将所述单个传输时间间隔t的时长信息、所述时延修正值k的信息和所述上行传输信息通知所述终端。
S207，接收所述终端根据所述单个传输时间间隔t的时长信息、所述时延修正值k的信息和所述上行传输信息传输的上行数据，完成上行传输。
在本发明实施例中，重点描述了上行传输信息所包含的内容，其具体根据上行数据发送的连续性来确定，确保终端可以清楚的明确上行传输的时间和方式。
请参照图3，为本发明上行传输的方法的第三实施例的流程示意图，在本实施例中，所述方法包括以下步骤：
S301，基站根据传输的业务类型确定单个传输时间间隔t的时长以及与所述业务类型对应的时延修正值k。
其中， t=2n*5m毫秒，m和n为整数，k为大于等于-4的整数。
S302，确定发送上行数据的时间个数。
S303，当发送上行数据的时间个数多于一个时，判断发送上行数据是否为占用连续多个发送时间。若是，则执行步骤S304，否则执行步骤S305。
可选地，若发送上行数据的时间个数为一个，则在所述上行授权信令中携带发送上行数据的时间和发送上行数据的时间个数，将所述上行授权信令发送给所述终端。
S304，在所述上行授权信令中携带第一次发送上行数据的时间和发送上行数据的时间个数，将所述上行授权信令发送给所述终端。
在步骤S304之后，可选择步骤S306-S308中的至少一种方式将相关参数通知终端，再执行步骤S309。
S305，在所述上行授权信令中携带第一次发送上行数据的时间、发送上行数据的时间个数以及每两次发送上行数据的时间的间隔，将所述上行授权信令发送给所述终端。
在步骤S305之后，可选择步骤S306-S308中的至少一种方式将相关参数通知终端，再执行步骤S309。
S306，配置映射表格用于保存所述单个传输时间间隔t的时长信息、所述时延修正值k的信息和所述上行传输信息，将所述映射表格发送给所述终端保存；当接收到所述终端上报的业务类型时，根据业务类型在所述映射表格中选择上行传输使用的信息并通过上行授权信令通知所述终端。
S307，接收所述终端上报的业务类型，根据业务类型确定单个传输时间间隔t的时长和时延修正值k，将确定的单个传输时间间隔t的时长和时延修正值k，以及上行传输信息通过无线资源控制信令发送给所述终端。
S308，基站在确定单个传输时间间隔t的时长、时延修正值k和上行传输信息之后，在所述给所述终端的上行授权信令中，通过下行控制信息的比特序列指示所述单个传输时间间隔t的时长、时延修正值k和上行传输信息的取值。
其中，所述终端上预存了下行控制信息比特序列与单个传输时间间隔t的时长、时延修正值k以及上行传输信息的映射关系表。
需要说明的是，单个传输时间间隔t的时长、时延修正值k和上行传输信息可以使用步骤S306-S308中任一方式通知终端，且三者可以使用相同的通知方式，也可以使用不同的通知方式，本发明实施例不做任何限定。
S309，接收所述终端根据所述单个传输时间间隔t的时长信息、所述时延修正值k的信息和所述上行传输信息传输的上行数据，完成上行传输。
在本实施例中，重点描述了基站通知终端相关参数的方式，对应于不同的通知方式，这些参数可以是静态的，也可以是半静态的，还可以是动态的。若参数是动态的，则参数的取值可以针对每次的上行授权信令进行变化，从而适应该终端用户不同的业务类型以及当前小区内的业务负荷，例如，当前小区内其他用户也有很多业务时，则当前终端用户的上行调度时延可以适当大一些，当小区内其他用户业务很少时，则当前终端用户的上行调度时延可以适当小一些，从而更加充分的利用系统资源。

在进一步的实施例中，向终端发送上行授权信令，在所述上行授权指令中指示上行数据的上行传输信息，包括：
确定发送上行数据的时间个数；

若占用连续的多个发送时间，则在所述上行授权信令中携带第一次发送上行数据的时间和发送上行数据的时间个数，将所述上行授权信令发送给所述终端；
若占用非连续的多个发送时间，则在所述上行授权信令中携带第一次发送上行数据的时间、发送上行数据的时间个数以及每两次发送上行数据的时间的间隔，将所述上行授权信令发送给所述终端。
在进一步的实施例中，若发送上行数据的时间个数为一个，则所述处理器2在所述上行授权信令中携带发送上行数据的时间和发送上行数据的时间个数，将所述上行授权信令发送给所述终端。
在进一步的实施例中，将所述单个传输时间间隔t的时长信息、所述时延修正值k的信息和所述上行传输信息通知所述终端，包括：

具体地，所述处理器2对上述指令的具体实现方法可参考图1至图3对应实施例中相关步骤的描述，在此不赘述。通过上述实施例的描述，本发明具有以下优点：
基站可以根据传输的业务类型确定了单个传输时间间隔t的时长以及与所述业务类型对应的时延修正值k，并且在上行授权信令中携带发送上行数据相关的传输信息，然后将这些参数和信息通知终端；终端便可以根据这些参数和信息确定传输上行数据的时间和方式，由于单个传输时间间隔t的值和时延修正值k根据业务类型确定，因此，可以充分满足不同业务的时延需求，尤其对于未来5G业务中一些时延要求较高的业务，可通过配置合适的t值和k值来适应业务需求，提高了系统的灵活性，同时也提升了用户的数据传输体验。
