本申请基于申请号为201611002088.6、申请日为2016年11月11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领域，尤其涉及一种小时隙的发送方法、装置和计算机可读存储介质。
背景技术
在过去的几十年中，移动通信经历了从语音业务到高速率宽带数据业务的飞跃发展。而随着移动互联网和物联网等新型业务的进一步发展，人们对移动网络的新需求将会进一步增加。一方面，预计未来移动网络数据流量将会呈现爆发式增长。另一方面，海量的设备连接和多样化的业务及应用是未来无线通信系统的重要特征之一，以人为中心的通信与以机器为中心的通信将会共存发展。
基于未来移动通信多样化的业务和应用需求，无线通信系统必须满足多样化的要求，包括在吞吐量、时延、可靠性、链接密度、成本、能耗、复杂性以及覆盖等多发面的要求，由此，针对5G系统的研究应运而生。5G系统在研究之初，将未来移动通信的可能场景或业务分为三类：增强的移动宽带(eMBB，enhanced Mobile Broadband)、超可靠低时延通信(URLLC，Ultra Reliable Low latency Communication)、以及海量的机器类通信(mMTC，massive Machine Type Communication)。eMBB、URLLC以及mMTC代表了三类不同的业务，具有不同的要求，例如，eMBB一般是宽带传输，需要提供较高的吞吐量，URLLC对可靠性和时延有要求，而mMTC 的要求是大连接、广覆盖以及低功耗。几种业务的不同要求决定了在发送时，它们对时域和频域的占用要求不一样。
小时隙(英文表达为mini-slot)或称为子时隙(英文表达为sub-slot)一般可以用于URLLC、非授权频谱或其他业务，能够用于小包的调度发送，同时能够满足低时延的要求。因此需要提供一种方法，来有效支持小时隙与时隙(slot)协作或单独发送。

本发明实施例还提供了一种小时隙的发送设备，所述设备包括：上文所述的小时隙的发送装置。所述设备可为基站等网元设备，也可为终端等用户设备。
下面结合具体场景实施例对本发明进行详细描述。
根据标准组织3GPP有关5G NR(New radio)的最新结论，一个子帧的长度定义为1ms。定义子帧长度的参考子载波间隔为15kHz。对于子载波间隔为60kHz或更小(如15/30kHz)，每个slot中包含7个或14个OFDM符号。对于大于60kHz的子载波间隔，每个时隙中包含14个OFDM符号。上述时隙中的循环前缀(CP，Cyclic prefix)为正常CP(或相同的CP开销)。
对于URLLC、非授权频谱以及其他场景，存在需求使用更小的slot来满足其时延或频谱效率方面的需求，因此标准正在讨论制定mini-slot(或称为subslot)。一般来说mini-slot的符号数需要小于slot包含的符号数。例如，如果slot确定为7个符号，则mini-slot长度包含的符号数需要小于7。
因此，需要考虑mini-slot(下文称为mini-slot、或小时隙)单独发送、或者和slot(下文中称为slot、或normal slot、或时隙、或正常时隙)、子帧等时间间隔(time interval)复用发送的问题。
下文中时隙/子帧等时间间隔中的符号序号从n＝0开始编号。例如第1个符号与符号0等价，以此类推。
以下方法或实施例可以单独使用或自由组合。
方法一：
限制时间间隔(time interval)中的前n个符号和后n个符号中至少之一不配置为mini-slot，也即满足以下至少之一：mini-slot的开始位置只能位于时间间隔中的第n+1个符号或之后符号；mini-slot的结束位置只能位于时间间隔的倒数第n+1个符号或之前符号。
其中，时间间隔可以是一个或多个slot、或子帧(subframes)、或帧(frame)、或调度间隔(scheduling intervals)、或控制间隔(control intervals)。其中，1<＝n<7。优选地，n＝1或2。
在本发明实施例中(包括本方法及其他方法)，时间间隔采用的子载波间隔可以为15kHz、或30kHz、或60kHz、或其他。为了避免复杂性和造成混淆，可以优选采用15kHz作为基准来定义mini-slot发送方法。或者，时间间隔采用的子载波间隔为基站发送/接收数据当前正在使用的子载波间隔。例如，该子载波间隔为基站发送eMBB数据使用的numerology(子载波间隔)。
mini-slot可以采用与时间间隔相同或不相同的numerology配置，例如时间间隔采用的子载波间隔为15kHz，而mini-slot采用的子载波间隔为15kHz或30kHz。
所述时间间隔中的符号和时间间隔的numerology相同。mini-slot中的 符号可以按照mini-slot的numerology配置发送。例如，一个mini-slot占用时间间隔中的两个符号，这两个符号可以按照时间间隔的numerology来定义。这两个符号进一步的可以按照mini-slot的numerology配置发送，例如，mini-slot的子载波间隔为30kHz，则时间间隔的这两个符号可以相应的定义为更小的四个符号。
可选的，可以在上述前n个符号或后n个符号中的一个或多个符号中配置发送控制信息。控制信息可以包括以下至少之一：时隙或子帧的结构信息、时隙或子帧的numerology、时隙或子帧的发送方向(DL-only、或UL-only、或DL-dominant、或UL-dominant、或DL/UL-both)、有无配置mini-slot的信息、mini-slot的配置信息、单个mini-slot的类型(对应包含的符号数)、mini-slot的聚合数量或时间长度、mini-slot的numerology、mini-slot的发送方向(DL-only、或UL-only、或DL-dominant、或UL-dominant、或DL/UL-both)。
上述控制信息可以针对以下时隙或子帧之一：
本时隙或本子帧；下一时隙或下一子帧；前一时隙或前一子帧；本时隙或本子帧开始的多个时隙或多个子帧；下一时隙或下一子帧开始的多个时隙或多个子帧；前一时隙或前一子帧开始的前多个时隙或多个子帧。
numerology意思为相关参数，例如包括以下参数至少之一：子载波间隔、符号长度、CP类型等等。DL-only意思为仅有下行发送，UL-only意思为仅有上行发送，DL-dominant意思为以发送DL为主，UL只有少量业务如UL控制信令发送。UL-dominant意思为以发送UL为主，DL只有少量业务如DL控制信令发送。DL/UL-both意思为DL data和UL data都有发送。
所述前或后n个符号或其中配置了控制信息的所述一个或多个符号可以采用与slot或子帧相同的numerology；或者，采用与mini-slot相同的numerology。优选地，采用与slot或子帧相同的numerology。其控制信息能够被利用slot或子帧numerology发送或接收数据的UE识别，从而对slot或子帧上的数据进行译码或解调时能够正确处理。例如：接收端知道该slot的部分符号被配置为mini-slot，因此不会对被配置为mini-slot的符号上数据进行合并译码，提高在slot上数据译码的准确性。
以slot为例：
限制slot的前n个符号和后n个符号中至少之一不配置为mini-slot。也即满足以下条件至少之一：
mini-slot的开始位置只能位于slot中的第n+1个符号或之后符号；mini-slot的结束位置只能位于slot的倒数第n+1个符号或之前符号；其中，1<＝n<7。优选的，n＝1或2。
可见，本发明实施例的slot的长度有可能不是mini-slot的整数倍，如果mini-slot可以从slot中的任意一个符号开始配置或结束，会造成单个mini-slot跨越两个slot，造成资源利用的碎片化，对mini-slot的业务接收以及slot的业务接收都会造成影响。
此外，按照目前各厂家的普遍观点，slot的第一个符号发送DL control，最后一个符号发送UL control，控制信息需要较高的可靠性和优先级，在slot的首尾符号不配置mini-slot，可以避免本小区控制信息的影响和邻区控制信息的跨链路干扰。
在slot的前n个符号或后n个符号不配置为mini-slot除了避免对slot/mini-slot的碎片化操作，也可以利用这n个符号来发送上述mini-slot的配置信息。
n的取值需要小于slot包含的符号数或其二分之一，为了降低对mini-slot配置灵活性的影响，优选n＝1或2。
假设子载波间隔为15kHz，slot包含7个OFDM符号，mini-slot包含2个OFDM符号。
限制slot的第1个符号(即符号0)不能配置为mini-slot，第2-7个符号(即符号1-6)可以根据需要配置为1个或多个的mini-slot。或者说，mini-slot的开始位置只能位于slot中符号1或之后符号。如图3所示。可选的，发送端可以在符号0上发送控制信息。
和/或，限制slot的第7个符号(即符号6)不能配置为mini-slot，第1-6个符号(即符号0-5)可以根据需要配置为1个或多个的mini-slot。或者说，mini-slot的结束位置只能位于slot中符号5或之前符号，如图4所示。 可选的，发送端可以在符号6上发送控制信息(该控制信息可以针对本slot，也可以针对下一个slot)。
方法二：
mini-slot的开始位置只能位于时间间隔中的第偶数个符号(如符号0/2/4等)或第奇数个符号(如符号1/3/5等)。或者，mini-slot的开始位置只能位于时间间隔中的符号序号与单个mini-slot长度成整数倍数关系的符号再偏移n个符号的符号；n＝0,1,2。或者，mini-slot的开始位置位于时间间隔中的第k个符号，所述k为设定取值，取值为正整数。
其中，时间间隔可以是一个或多个时隙(slots)、或子帧(subframes)、或帧(frames)、或调度间隔(scheduling intervals)、或控制间隔(control intervals)。
可选地，可以限制mini-slot的开始位置和结束位置不能位于两个不同时隙中。也即：从mini-slot的开始位置到slot的结束部分不足以配置一个mini-slot时，不配置mini-slot发送。上述主要针对单个mini-slot而言。多个聚合的mini-slot可以分布在不同的slot中(但是其中单个mini-slot仍须满足上述要求)，以支持灵活的mini-slot聚合，适用不同大小数据包发送。或者，同样限制多个聚合的mini-slot分布在同一个slot中，原因是mini-slot的设计初衷就是为了支持小包业务的发送以及满足时延要求，一般数据包不会太大。聚合的mini-slot跨越多个slot会对多个slot上发送的数据会造成影响。其聚合后的大小已经接近或超过slot长度，其业务可以被mini-slot和slot的聚合来代替。
对于“mini-slot的开始位置只能位于slot中的符号序号与单个mini-slot长度成整数倍数关系的符号再偏移n个符号的符号”，如果偏移量n＝0，如果mini-slot长度为2个符号，那么它的开始位置只能位于符号0,2,4等等。如果mini-slot长度为3个符号，那么它的开始位置只能位于符号0,3,6等等。
如果偏移量n＝1，例如：如果mini-slot长度为2个符号，那么它的开始位置只能位于符号1,3,5(符号0/2/4再偏移一个符号)等等。如果mini-slot长度为3个符号，那么它的开始位置只能位于符号1,4,7(符号0/3/6再偏移一个符号)等等。
可选地，发送端可以在时隙的前n个符号发送控制信息，控制信息可以与方法一种的控制信息相同。
对于“mini-slot的开始位置位于时间间隔中的第k个符号”，即可以根据时间间隔(如slot)的结构或符号数来确定mini-slot的开始位置在时间间隔中的第预设个符号上。
例如，一个slot包括7个符号，那么可以预设mini-slot的开始位置位于时间间隔中的第1、4、6个符号。如果mini-slot的开始位置位于第1个符号，那么mini-slot包含符号0、1、2三个符号。如果mini-slot的开始位置位于第4个符号，那么mini-slot包含符号3、4两个符号。如果mini-slot的开始位置位于第6个符号，那么mini-slot包含符号5、6两个符号。或者，mini-slot开始位置在slot上的第k个符号，第k个符号可以为符号0、或符号2、或符号4，即slot上的前两个mini-slot包含2个符号，第三个mini-slot可包含3个符号。
也即，如果slot的长度为7个符号，mini-slot开始位置在slot上的第k个符号可以为：方案一：符号0、3、或5；方案二：为符号0、2、或4。且可以根据开始位置的符号序数来配置不同长度的mini-slot类型。其中符号0(或者方案二中的符号6)可以发送控制信息，控制信息可以和方法一中的控制信息类似或相同。
可见，本实施例限制mini-slot的起始位置或结束位置一方面可以避免UE盲检的复杂度和节省功耗，同样可以避免mini-slot对slot业务的影响。
方法三：
设置mini-slot满足以下条件至少之一：
设置单个mini-slot不能跨slot配置，也即单个mini-slot上的符号只能分布在同一个slot上；
多个mini-slot的聚合不能跨三个slot，也即多个聚合的mini-slot最多分布在两个slot上。
例如，发送端按照slot的numerology(子载波间隔为15kHz)通信，这个时候需要发送URLLC业务，需要配置mini-slot(子载波间隔为15kHz 或30kHz或其他)。那么单个mini-slot的首尾符号需要落在同一个slot上。
如果URLLC的业务相对较大，单个mini-slot发送不了，则需要多个mini-slot聚合发送。多个mini-slot的聚合不能跨三个slot，也即多个聚合的mini-slot最多分布在两个slot上。更大的数据包应该通过slot来承载，或slot与mini-slot的聚合来承载。限制mini-slot的聚合长度，一方面能够减少mini-slot业务对slot业务的影响，另一方面也不违背设置mini-slot的初衷，即利用mini-slot发送小包业务，降低发送时延。
方法四：
如果mini-slot为1个符号，那么单独1个符号的mini-slot无法以时分复用模式(TDM)方式发送控制信道、参考信号和数据信道。那么mini-slot的使用方式有可能是以不同的numerology与slot复用发送。这同样适用于包含2个或更多个符号数的mini-slot。
譬如以15kHz子载波间隔为参考numerology，假设一个slot包括7个OFDM符号(即一个slot等效于7个OFDM符号时长)，一个mini-slot包括1个OFDM符号。那么，对于30kHz来说，一个mini-slot包括2个OFDM符号(只占用15kHz的一个符号长度)；对于60kHz来说，一个mini-slot包括4个OFDM符号(只占用15kHz的一个符号长度)等等。mini-slot以30kHz或更大的子载波间隔的numerology与15kHz的子载波间隔对应的slot进行复用发送。
类似地，仍以15kHz子载波间隔为参考numerology，假设一个slot包括7个OFDM符号，一个mini-slot包括2个OFDM符号。那么，对于30kHz来说，一个mini-slot包括4个OFDM符号(只占用15kHz的2个符号长度)；对于60kHz来说，一个mini-slot包括8个OFDM符号(只占用15kHz的2个符号长度)等等。mini-slot以30kHz或更大的子载波间隔的numerology与15kHz的子载波间隔对应的slot进行复用发送。这种情况下mini-slot的时间长度可以是不变的。如图5所示。
Mini-slot的开始位置和结束位置中至少之一应该与slot中的符号边界对齐，无论mini-slot和slot采用相同或不同的numerology。
可选地，Mini-slot的开始位置和结束位置中至少之一应该与子载波间 隔为15kHz的slot中的符号边界对齐，无论mini-slot采用与15kHz相同或不同的numerology，例如mini-slot采用30kHz或其他子载波间隔配置。
可见，本实施例Mini-slot的开始位置和结束位置中至少之一应该与slot中的符号边界对齐，一方面可以降低UE盲检的复杂度和功耗，另一方面可以降低mini-slot对slot的影响，避免资源浪费。
另外一种可能性，不论采用何种numerology或子载波间隔，mini-slot都包含固定数目的符号。例如一个mini-slot包括2个OFDM符号。那么无论采用15kHz，还是采用30kHz或其他子载波间隔，mini-slot都是只包括该子载波间隔对应的2个OFDM符号。实际上，这种情况下mini-slot的时间长度是随着子载波间隔变大而变小。当mini-slot单独发送或与slot复用发送时，上述方法同样适合此种情况。
或者，mini-slot包括的符号数可以有几种选择，例如：已包括1个符号、或2个符号、或3个符号。采用哪一种类型的mini-slot可以动态配置。
