 附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图2是本发明配置时域调度单元的方法的第二实施例的流程示意图；
图3是本发明配置时域调度单元的方法的第三实施例的流程示意图；
图4是本发明实施例提供的基站的组成示意图；
图5是本发明实施例提供的另一种基站的结构示意图。
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。
本发明说明书、权利要求书和附图中出现的术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
未来5G通信主要场景包括以下三种：增强的移动宽带（enhanced Mobile BroadBand，eMBB），大量机器类通信（massive Machine Type Communications，mMTC）和高可靠低时延（Ultra-Reliable and Low Latency Communications，URLLC)。这三种场景所针对的业务类型不一样，其需求也不一样。
例如eMBB业务，两个主要的指标是高带宽和低时延（要求4ms）。在未来的高频通信上，可能支持100MHz的大带宽，而且很可能某个时刻整个带宽都直接分配给一个用户。而上行调度时延和HARQ反馈时延也会带来时延影响。
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。
对于URLLC业务，时延要求是0.5ms，也需要减小时域调度粒度，上行调度时延和HARQ反馈时延带来的时延影响。
因此，本发明实施例公开一种时域调度单元的配置方法及基站，在本发明实施例中，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业务来配置时域调度单元的时间长度以及时域调度单元的具体结构，包括具体组成和每个组成部分的具体长度即占用的子帧和/或符号数。下面具体结合图1-图3进行说明。
请参照图1，为本发明配置时域调度单元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，基站确定所述时域调度单元的时间长度。
其中，所述时域调度单元包括下行链路、保护时隙以及上行链路，且所述时域调度单元的时间长度为2n*5m毫秒，m和n为整数。
即系统的最小的时域调度粒度中，可包括下行链路（DL），保护时隙（GP）和上行链路（UL），三者可以在时域调度单元中依次排列。当然，根据业务传输信息的不同需求，三者排序的方式除了本实施例中描述的DL-GP-UL的顺序之外，也可以是GP-UL-DL或UL-DL-GP的排序，本发明实施例不作任何限定。为了便于描述说明，以下均采用DL-GP-UL的顺序进行介绍。
此外，需要说明的是，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时域调度单元。例如，针对A业务，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，时域调度单元的时间长度则依次可以为0.125ms，0.25ms、0.5ms、2ms、4ms、8ms或1ms。针对B业务，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，时域调度单元的时间长度则依次为0.008ms、0.04ms、0.2ms、5ms、25ms、125ms或1ms。当然，针对另一种业务如C业务，m和n可以都不为0，如m为-1，n为2，则时域调度单元的时间长度为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。
S102，根据业务需求配置所述时域调度单元传输的信息。
其中，所述时域调度单元传输的信息包括上行信息和/或下行信息。
可选地，若进行现有业务时若基站需要向终端发送数据，则时域调度单元主要传输下行信息；若进行现有业务时终端需要向基站发送数据，则时域调度单元主要传输上行信息；当然，下行信息和上行信息也可以在一个时域调度单元内同时传输。
S103，根据所述时域调度单元传输的信息设置所述时域调度单元中的下行链路、保护时隙以及上行链路的长度。
例如，在以DL为主时，即时域调度单元传输的信息包括下行数据时，DL占用的符号数大于UL。DL包含了下行数据，而UL占用的符号数较少，主要可包括探测参考信号（Sounding Reference Signal，SRS）和/或上行控制信息（Uplink Control Information，UCI）和/或随机接入前导码，GP则占用1-2个符合即可。
在以UL为主时，即时域调度单元传输的信息包括上行数据时，UL占用的符号数大于DL。DL只包含下行控制信息（Downlink Control Information，DCI）或参考信号， UL包含了较多的符号数且包含上行数据或随机接入前导码（RA preamble），GP则占用1-2个符号即可。
这样，通过确定时域调度单元的长度，可满足不同业务的时域调度粒度需求，并且在根据业务需求配置需要时域调度单元传输的信息之后，根据传输的信息设置其中的下行链路、保护时隙以及上行链路的具体长度，使得基站进行时域资源调度时十分的灵活，且在一个时域调度单元内可同时进行下行链路和上行链路的传输，使得下行链路的下行数据在同一时域调度单元内能得到尽快反馈或者上行授权调度的上行数据能尽快发送，使得系统能够更好地适应时延要求较高的5G新业务及未来可能的新业务，从而大大提升了系统的处理效率以及用户的使用体验。
