Description

资源调度方法及资源调度装置
本申请要求于2016年10月31日提交中国专利局、申请号为201610977460.9、发明名称为“资源调度方法及资源调度装置”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，具体而言，涉及一种资源调度方法和一种资源调度装置。
背景技术
现有的4G以及4.5G移动通信技术，都是基于LTE(Long Term Evolution，长期演进)及LTE-A(LTE-Advanced)的无线接入技术、时频资源粒度和帧结构等。比如目前LTE系统能支持的最大单载波带宽为20MHz，若要支持更大带宽，只能依靠载波聚合(Carrier Aggregation，简称CA)的使用。另外，目前的帧结构主要包括：FDD(Frequency Division Duplexing，频分双工)帧结构、TDD(Time Division Duplexing，时分双工)帧结构和LAA(LTE Assisted Access，LTE辅助接入)非授权载波使用的动态帧结构。不管是哪种帧结构，都包含10个子帧，每个子帧为1ms，每个子帧包含两个slot(时隙)，一个slot为0.5ms，每个slot又包含7个symbol(符号)。频域方面，在LTE系统中，子载波间隔主要是15KHz，一个RB(Resource Block，资源块)包含了12个子载波。而在NB-IoT(Narrow Band Internet of Things，基于蜂窝的窄带物联网)中又提出一种新的3.75KHz的子载波间隔，而且NB-IoT的载波带宽仅有180KHz。
在资源分配方面，FDD帧结构和TDD帧结构都是以1ms子帧为时域调度粒度，除了TDD帧结构中的特殊子帧内的DwPTS(Downlink Pilot  Time Slot，下行导频时隙)用于传输数据时，时域调度粒度是小于1ms的。同样在LAA非授权载波使用的帧结构中也出现了复用DwPTS作为partial subframe的下行调度时域粒度，同时也使用了1ms整子帧的调度粒度。而在FDD帧结构和TDD帧结构中，除了TDD帧结构中的特殊子帧既有下行发送时间和上行发送时间外，其它的子帧都是上行发送或下行发送要么时域分开要么频域分开。
可见，目前的帧结构和频域资源的粒度都会使得资源分配不够灵活，而上行调度机制与HARQ(Hybrid Automatic Repeat Request，混合自动重传请求)反馈机制等的时间间隔又使得时延较大，20MHz带宽也不满足高带宽需求。
未来5G通信主要场景包括以下三种：eMBB(enhanced Mobile Broadband，增强的移动宽带网络)，mMTC(massive Machine Type Communication，大规模机器类通讯)和URLLC(Ultra-Reliable and Low Latency Communications，高可靠低时延通信)。这三种场景所针对的业务类型不一样，其需求也不一样。比如：eMBB业务的两个主要指标是高带宽和低时延，在未来的高频通信上，eMBB业务可能支持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使用，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，也需要减少上行调度时延和HARQ反馈时延带来的时延影响。
也就是说由于业务的多样化，使得目前固定的帧结构、固定的频域资源粒度和时域资源粒度会造成较大的上行调度时延和较长的HARQ反馈时延，并且较小的载波带宽也无法满足业务的多样化需求，而5G通信希望能够做到足够灵活，任何一个资源都可能动态的进行调度以随时使用。
目前，针对5G的讨论会议已经达成了以下共识：子帧长度定义为1ms，其参考的子载波间隔是15KHz，这个子帧长度是由于用户终端来进行基本的下行子帧同步时使用的。而对于调度单元slot(时隙)，当子载波间隔小于60KHz时，slot为7个或14个符号(Symbol)长度；当子载 波间隔大于60KHz时，slot为14个符号长度。并且可以支持多个slot聚合的数据传输。
同时，在未来的5G通信中，不同的用户可能会使用不同的子载波间隔，因此当多个用户使用不同子载波间隔的情况下，如何确保在资源分配时的信令最小化，并且确保用户能够准确获知被分配的资源是亟待解决的技术问题。
发明内容
本发明正是基于上述技术问题至少之一，提出了一种新的资源调度方案，使得在多个终端使用不同子载波间隔的情况下，能够有效减少资源分配时的信令开销，并且也能够确保用户准确获知自身被分配到的时间资源，提高了系统吞吐量。
有鉴于此，根据本发明的第一方面，提出了一种资源调度方法，包括：通知终端在进行通信时使用的子载波间隔、每个时隙包含的符号个数和每个符号的长度；在需要向所述终端分配通信资源时，向所述终端指示聚合的多个时隙中第一个时隙的位置和所述多个时隙的个数，以向所述终端指示向其分配的通信资源。
在该技术方案中，当需要向终端分配通信资源时，通过向终端指示聚合的多个时隙中第一个时隙的位置和这聚合的多个时隙的个数，使得终端能够根据使用的子载波间隔、每个时隙包含的符号个数和每个符号的长度来确定基站向其分配的通信资源。可见，本发明的技术方案采用多个时隙聚合的调度方式来向终端分配通信资源，而在向终端指示分配的通信资源时，仅需要指示聚合的多个时隙中第一个时隙的位置和聚合的多个时隙的个数，相比于需要针对每个时隙都发送调度信令的方案，本发明的技术方案有效减少了资源分配时的信令开销，并且也能够使用户准确获知自身被分配到的时间资源，提高了系统吞吐量。
根据本发明的第二方面，还提出了一种资源调度方法，包括：接收基站通知的终端在进行通信时使用的子载波间隔、每个时隙包含的符号个数和每个符号的长度；接收所述基站发送的调度信息；若所述调度信息指示 聚合的多个时隙中第一个时隙的位置和所述多个时隙的个数，则根据所述第一个时隙的位置、所述多个时隙的个数、每个时隙包含的符号个数和每个符号的长度，确定所述基站分配的通信资源；基于所述基站分配的通信资源进行通信。
在该技术方案中，当基站发送的调度信息指示聚合的多个时隙中第一个时隙的位置和这聚合的多个时隙的个数时，说明基站是通过多个时隙聚合的调度方式来向终端分配通信资源，并且在向终端指示分配的通信资源时，仅需要指示聚合的多个时隙中第一个时隙的位置和聚合的多个时隙的个数，相比于需要针对每个时隙都发送调度信令的方案，本发明的技术方案有效减少了资源分配时的信令开销，并且也使得用户能够准确获知自身被分配到的时间资源，提高了系统吞吐量。
根据本发明的第三方面，还提出了一种资源调度装置，包括：第一通知单元，用于通知终端在进行通信时使用的子载波间隔、每个时隙包含的符号个数和每个符号的长度；指示单元，用于在需要向所述终端分配通信资源时，向所述终端指示聚合的多个时隙中第一个时隙的位置和所述多个时隙的个数，以向所述终端指示向其分配的通信资源。
在该技术方案中，当需要向终端分配通信资源时，通过向终端指示聚合的多个时隙中第一个时隙的位置和这聚合的多个时隙的个数，使得终端能够根据使用的子载波间隔、每个时隙包含的符号个数和每个符号的长度来确定基站向其分配的通信资源。可见，本发明的技术方案采用多个时隙聚合的调度方式来向终端分配通信资源，而在向终端指示分配的通信资源时，仅需要指示聚合的多个时隙中第一个时隙的位置和聚合的多个时隙的个数，相比于需要针对每个时隙都发送调度信令的方案，本发明的技术方案有效减少了资源分配时的信令开销，并且也能够使用户准确获知自身被分配到的时间资源，提高了系统吞吐量。
根据本发明的第四方面，还提出了一种资源调度装置，包括：第一接收单元，用于接收基站通知的终端在进行通信时使用的子载波间隔、每个时隙包含的符号个数和每个符号的长度；第二接收单元，用于接收所述基站发送的调度信息；确定单元，用于在所述调度信息指示聚合的多个时隙 中第一个时隙的位置和所述多个时隙的个数时，根据所述第一个时隙的位置、所述多个时隙的个数、每个时隙包含的符号个数和每个符号的长度，确定所述基站分配的通信资源；通信单元，用于基于所述基站分配的通信资源进行通信。
在该技术方案中，当基站发送的调度信息指示聚合的多个时隙中第一个时隙的位置和这聚合的多个时隙的个数时，说明基站是通过多个时隙聚合的调度方式来向终端分配通信资源，并且在向终端指示分配的通信资源时，仅需要指示聚合的多个时隙中第一个时隙的位置和聚合的多个时隙的个数，相比于需要针对每个时隙都发送调度信令的方案，本发明的技术方案有效减少了资源分配时的信令开销，并且也使得用户能够准确获知自身被分配到的时间资源，提高了系统吞吐量。
通过以上技术方案，使得在多个终端使用不同子载波间隔的情况下，能够有效减少资源分配时的信令开销，并且也能够确保用户准确获知自身被分配到的时间资源，提高了系统吞吐量。

具体实施方式
为了能够更清楚地理解本发明的上述目的、特征和优点，下面结合附图和具体实施方式对本发明进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是，本发明还可以采用其他不同于在此描述的其他方式来实施，因此，本发明的保护范围并不受下面公开的具体实施例的限制。
图1示出了根据本发明的第一个实施例的资源调度方法的流程示意图，该资源调度方法适用于基站。
如图1所示，根据本发明的第一个实施例的资源调度方法，包括：
步骤S10，通知终端在进行通信时使用的子载波间隔、每个时隙包含的符号个数和每个符号的长度。
步骤S12，在需要向所述终端分配通信资源时，向所述终端指示聚合的多个时隙中第一个时隙的位置和所述多个时隙的个数，以向所述终端指示向其分配的通信资源。
其中，优选地，可以通过DCI信令向所述终端指示聚合的多个时隙中第一个时隙的位置和所述多个时隙的个数，其中，所述DCI信令的格式与对所述终端进行单个时隙调度时发送的DCI信令的格式不相同。
在图1所示的技术方案中，当需要向终端分配通信资源时，通过向终端指示聚合的多个时隙中第一个时隙的位置和这聚合的多个时隙的个数，使得终端能够根据使用的子载波间隔、每个时隙包含的符号个数和每个符号的长度来确定基站向其分配的通信资源。可见，本发明的技术方案采用多个时隙聚合的调度方式来向终端分配通信资源，而在向终端指示分配的通信资源时，仅需要指示聚合的多个时隙中第一个时隙的位置和聚合的多个时隙的个数，相比于需要针对每个时隙都发送调度信令的方案，本发明的技术方案有效减少了资源分配时的信令开销，并且也能够使用户准确获知自身被分配到的时间资源，提高了系统吞吐量。
在上述技术方案中，优选地，所述的资源调度方法还包括：确定所述终端能够支持的最大可聚合的时隙个数；将确定的所述最大可聚合的时隙 个数通知给所述终端。优选地，可以通过RRC信令半静态的将确定的最大可聚合的时隙个数通知给所述终端。
在该技术方案中，通过将确定的终端能够支持的最大可聚合的时隙个数通知给终端，使得终端能够据此来确定基站后续在指示调度的时隙个数时的DCI信令的比特数，进而能够正确解码该DCI信令，以获知基站的调度信息。其中，终端在获知最大可聚合的时隙个数之后可以存储在自身的芯片中；此外，若终端能够支持的最大可聚合的时隙个数是提前就确定好的，则可以在基站与终端通信之前就预存在终端的芯片中。
进一步地，确定所述终端能够支持的最大可聚合的时隙个数的步骤，具体包括：根据一个子帧的时间长度和所述每个符号的长度，确定一个子帧内包含的时隙个数；将整数个子帧内包含的时隙总个数或非整数个子帧内包含的时隙总个数作为所述最大可聚合的时隙个数。
其中，在所述最大可聚合的时隙个数为一个子帧内包含的时隙总个数的情况下，能够聚合的时隙包括单个子帧内的时隙或相邻子帧之间的时隙。即本发明的技术方案支持子帧内的时隙聚合和子帧之间的时隙聚合。
在本发明的一个实施例中，不同的子载波间隔下的最大可聚合的时隙个数相同或不同；和/或
不同的子载波间隔下的最大可聚合的时隙个数对应的时长相同或不同。
在上述任一技术方案中，优选地，针对上行调度确定的最大可聚合的时隙个数与针对下行调度确定的最大可聚合的时隙个数相同或不同。
在上述任一技术方案中，优选地，在所述多个时隙中传输数据时所采用的编码与调制方式相同；和/或
在指示所述多个时隙对应的HARQ进程编号时，仅指示所述多个时隙中的一个时隙对应的HARQ进程编号；和/或

若在所述多个时隙中的任一时隙内确定需要将已分配给所述终端的指定时隙对应的频域资源中的部分资源分配给其它终端，则在所述任一时隙内向所述终端指示所述指定时隙对应的频域资源和其中被分配给其它终端使用的部分资源，
其中，所述指定时隙为所述多个时隙中的一个或多个时隙。
在该实施例中，由于不同终端使用的子载波间隔可能不同，因此基站基于资源最大化利用的考虑，可能会将已分配给某一终端的频域资源中的部分资源分配给其它终端使用，比如将向使用较大子载波间隔的终端分配的频域资源中的一部分资源分配给使用较小子载波间隔的其它终端，因此通过该实施例中的指示方式(既可以在指示聚合的多个时隙时进行指示，也可以在聚合的多个时隙中的其中一个时隙内进行指示)，可以确保终端准确获知自身被分配的通信资源，以便于终端通过被分配的通信资源来接收或发送数据。
图2示出了根据本发明的第一个实施例的资源调度装置的结构示意图。
如图2所示，根据本发明的第一个实施例的资源调度装置200，包括：第一通知单元202和指示单元204。
其中，第一通知单元202用于通知终端在进行通信时使用的子载波间隔、每个时隙包含的符号个数和每个符号的长度；指示单元204用于在需要向终端分配通信资源时，向所述终端指示聚合的多个时隙中第一个时隙的位置和所述多个时隙的个数，以向所述终端指示向其分配的通信资源。
在该技术方案中，当需要向终端分配通信资源时，通过向终端指示聚合的多个时隙中第一个时隙的位置和这聚合的多个时隙的个数，使得终端能够根据使用的子载波间隔、每个时隙包含的符号个数和每个符号的长度来确定基站向其分配的通信资源。可见，本发明的技术方案采用多个时隙聚合的调度方式来向终端分配通信资源，而在向终端指示分配的通信资源 时，仅需要指示聚合的多个时隙中第一个时隙的位置和聚合的多个时隙的个数，相比于需要针对每个时隙都发送调度信令的方案，本发明的技术方案有效减少了资源分配时的信令开销，并且也能够使用户准确获知自身被分配到的时间资源，提高了系统吞吐量。
进一步地，如图3所示，根据本发明的第二个实施例的资源调度装置300，在具有如图2中所示的第一通知单元202和指示单元204的基础上，还包括：确定单元302和第二通知单元304。
其中，确定单元302用于确定所述终端能够支持的最大可聚合的时隙个数；第二通知单元304用于将所述确定单元302确定的所述最大可聚合的时隙个数通知给所述终端。
在该技术方案中，通过将确定的终端能够支持的最大可聚合的时隙个数通知给终端，使得终端能够据此来确定基站后续在指示调度的时隙个数时的DCI信令的比特数，进而能够正确解码该DCI信令，以获知基站的调度信息。其中，终端在获知最大可聚合的时隙个数之后可以存储在自身的芯片中；此外，若终端能够支持的最大可聚合的时隙个数是提前就确定好的，则可以在基站与终端通信之前就预存在终端的芯片中。
进一步地，所述确定单元302具体用于：根据一个子帧的时间长度和所述每个符号的长度，确定一个子帧内包含的时隙个数；将整数个子帧内包含的时隙总个数或非整数个子帧内包含的时隙总个数作为所述最大可聚合的时隙个数。

在上述任一技术方案中，优选地，针对上行调度确定的最大可聚合的时隙个数与针对下行调度确定的最大可聚合的时隙个数相同或不同。
在上述任一技术方案中，优选地，所述指示单元204具体用于：通过DCI信令向所述终端指示聚合的多个时隙中第一个时隙的位置和所述多个时隙的个数，其中，所述DCI信令的格式与对所述终端进行单个时隙调度时发送的DCI信令的格式不相同。

若需要将已分配给所述终端的指定时隙对应的频域资源中的部分资源分配给其它终端，则在向所述终端指示所述多个时隙中第一个时隙的位置和所述多个时隙的个数之后或同时，向所述终端指示所述指定时隙对应的频域资源和其中被分配给所述其它终端使用的部分资源，和/或
若在所述多个时隙中的任一时隙内确定需要将已分配给所述终端的指定时隙对应的频域资源中的部分资源分配给其它终端，则在所述任一时隙内向所述终端指示所述指定时隙对应的频域资源和其中被分配给其它终端使用的部分资源，
其中，所述指定时隙为所述多个时隙中的一个或多个时隙。
在该实施例中，由于不同终端使用的子载波间隔可能不同，因此基站基于资源最大化利用的考虑，可能会将已分配给某一终端的频域资源中的部分资源分配给其它终端使用，比如将向使用较大子载波间隔的终端分配的频域资源中的一部分资源分配给使用较小子载波间隔的其它终端，因此通过该实施例中的指示方式(既可以在指示聚合的多个时隙时进行指示，也可以在聚合的多个时隙中的其中一个时隙内进行指示)，可以确保终端准确获知自身被分配的通信资源，以便于终端通过被分配的通信资源来接 收或发送数据。
本发明还提出了一种基站，包括：如图2中所示的资源调度装置200，或如图3中所示的资源调度装置300。
图4示出了根据本发明的第二个实施例的资源调度方法的流程示意图，该资源调度方法适用于终端。
如图4所示，根据本发明的第二个实施例的资源调度方法，包括：
步骤S40，接收基站通知的终端在进行通信时使用的子载波间隔、每个时隙包含的符号个数和每个符号的长度。

本发明还提出了一种终端，包括：如图5中所示的资源调度装置500。
综上，本发明的技术方案主要是针对5G NR(New Radio，新的无线技术)多个时隙聚合调度的信令设计问题，具体包括如下几个方面：
一、基站需要通过RRC信令通知用户调度使用的子载波间隔是多少，每个slot包含几个符号，每个符号长度多少。进而用户可以根据每个slot包含的符号数和每个符号的长度来确定每个slot的时间长度，然后就可以确定一个子帧中即1ms内包含的slot的数目值。
列举具体示例如下：
1、比如子载波间隔为15KHz，那么一个子帧1ms内包含14个符号，若一个slot是7个或14个符号，则一个子帧包含2个或1个slot。
2、比如子载波间隔为30KHz，那么一个子帧1ms内包含28个符号，若一个slot是7个或14个符号，则一个子帧包含4个或2个slot。
3、比如子载波间隔为60KHz，那么一个子帧1ms内包含56个符号，若一个slot是7个或14个符号，则一个子帧包含8个或4个slot。
4、比如子载波间隔为120KHz，那么一个子帧1ms内包含112个符号，若一个slot是14个符号，则一个子帧包含8个slot。
二、基站需要确认终端可以支持的最大可聚合的slot数目。
1、如果只支持一个子帧1ms内的slot的聚合，那么最大可聚合的slot数目可以是一个子帧内包含的slot数目。当然，若最大可聚合的slot数目是一个子帧内包含的slot数目，那么也可以是子帧之间的slot聚合。
2、如果可以支持超过1ms的slot的聚合，那么既可以是子帧内的slot的聚合也可以是子帧之间的slot的聚合。在这种情况下，可以支持的最大可聚合的slot的数目可以是整数个子帧内包含的slot数目，也可以是非整数个子帧内的slot的数目。
3、不同的子载波间隔对应的最大可聚合的slot数目可以一样，也可以不一样，并且不同的子载波间隔对应的最大可聚合的slot数目的时长可以一样，也可以不一样。
三、基站在确定了终端能够支持的最大可聚合的slot数目之后，通过RRC信令通知给用户，进而用户能够根据最大可聚合的slot数目来确定基站在后续指示聚合的slot数目时使用的DCI信令的bit数，以确保终端能够正确解析基站发送的DCI信令。
比如最大可聚合的slot数目为4个，则2bit可以指示支持1个，2个，3个或4个；
比如最大可聚合的slot数目为8个，则3bit可以指示支持1个，2个，3个……或8个；
……
这里需要指出的是支持1个slot调度的DCI信令的格式和支持超过1个slot(即聚合slot)调度的DCI信令的格式可以不一样，并且这两个格式使用RRC信令独立启动或关闭。
四、当终端支持的可聚合的slot是连续的多个slot时，基站向用户指示向其分配的资源使用的DCI信令只需要指示第一个被调度的slot的位置，以及聚合的slot数目即可，进而用户能够根据使用的子载波间隔、每个slot包含的符号个数和每个符号的长度来确定基站向其分配的通信资源。
五、在聚合的多个slot中传输数据时采用的MCS(Modulation and Coding Scheme，调制与编码策略)一样；聚合的多个slot中的HARQ ID 只需要指示其中一个，其它的按预定义的规律获得(每个slot中有一个HARQ，因此在指示其中的一个HARQ ID之后，能够据此获知其它slot中的HARQ ID)；聚合的多个slot需要分别发送new data指示，且每个slot发送的new data指示占用1bit；聚合的多个slot对应的RV(Redundancy Version，冗余版本)分别进行指示。
六、上行和下行支持的最大可聚合的slot数目可以相同，也可以不同。
