技术领域
本公开涉及通信技术领域，尤其涉及一种下行资源抢占方法、装置、电子设备、存储介质及计算机程序产品。
背景技术
在第五代移动通信技术(5th Generation Mobile Communication Technology，简称5G)中，无线资源包括时域资源、频域资源和波束资源。通常的，多个终端可以通过不同的时域资源区分，而使用相同的频域资源和波束资源实现数据传输；多个终端也可以采用不同的频域资源区分，而使用相同的时域资源和波束资源实现数据传输；或者，多个终端还可以通过不同的波束资源区分，而使用相同的时域资源和频域资源(Multi-User Multiple-Input Multiple-Output，MU-MIMO)实现数据传输。
在下行无线资源传输过程中，突发的超低时延高可靠通信(Ultra-reliable low-latency communication,URLLC)业务可以占据正在进行的增强型移动宽带(Enhance mobile broad-band,eMBB)业务所用资源，以保证时延要求。eMBB用户设备被URLLC业务抢占(preemption)会影响eMBB用户设备。
在相关技术中，为了将更高优先级的URLLC业务安排在正在进行的EMBB用户设备传输所使用的资源上，通常采用抢占机制(有时称为穿刺或打孔)，通过所述机制，在eMBB传输中的一定数量的符号被URLLC传输打孔。然而，上述抢占机制无法合理利用无线资源，造成无线资源冗余的问题。

图1示出了可以应用于本公开实施例的下行资源抢占方法或下行资源抢占装置的示例性无线通信系统100的示意图。
如图1所示，无线通信系统100可以包括基站101、eMBB用户设备102和URLLC用户设备103。eMBB用户设备102的数量包括多个，在图1中，设有7个eMBB用户设备102，即eMBB UE(User Equipment，用户设备)1～eMBB UE7。
eMBB用户设备102和URLLC用户设备103分别通过网络与基站101进行数据传输。网络用以在eMBB用户设备102、URLLC用户设备103与基站101之间提供通信链路的介质，可以是有线网络，也可以是无线网络。
在一些实施例中，上述的无线网络或有线网络使用标准通信技术和/或协议。网络通常为因特网、但也可以是任何网络，包括但不限于局域网(Local Area Network，LAN)、城域网(Metropolitan Area Network，MAN)、广域网(Wide Area Network，WAN)、移动、有线或者无线网络、专用网络或者虚拟专用网络的任何组合)。在一些实施例中，使用包括超文本标记语言(Hyper Text Mark-up Language，HTML)、可扩展标记语言(Extensible MarkupLanguage，XML)等的技术和/或格式来代表通过网络交换的数据。此外还可以使用诸如安全套接字层(Secure Socket Layer，SSL)、传输层安全(Transport Layer Security，TLS)、虚拟专用网络(Virtual Private Network，VPN)、网际协议安全(Internet ProtocolSecurity，IPsec)等常规加密技术来加密所有或者一些链路。在另一些实施例中，还可以使用定制和/或专用数据通信技术取代或者补充上述数据通信技术。
eMBB用户设备从基站101下行链路上接收eMBB传输，而URLLC用户设备103使用与eMBB传输共享的资源从基站101接收下行链路上的URLLC传输。
eMBB用户设备102和URLLC用户设备103可以是各种电子设备，包括但不限于智能手机、平板电脑、膝上型便携计算机、台式计算机、可穿戴设备、增强现实设备、虚拟现实设备等。
在一些实施例中，不同的eMBB用户设备102和URLLC用户设备103中安装的应用程序的客户端是相同的，或基于不同操作系统的同一类型应用程序的客户端。基于终端平台的不同，该应用程序的客户端的具体形态也可以不同，比如，该应用程序客户端可以是手机客户端、PC客户端等。
本领域技术人员可以知晓，图1中的基站101、eMBB用户设备102和URLLC用户设备103的数量仅仅是示意性的，根据实际需要，可以具有任意数目的基站101、eMBB用户设备102和URLLC用户设备103。本公开实施例对此不作限定。
本公开提供的方案，获取URLLC用户设备103的待调度无线资源，综合考虑了 URLLC用户设备103和eMBB用户设备102在时域资源、频域资源、波束资源以及小区同一时刻最大调度的业务波束个数对资源抢占情况的影响，当URLLC用户设备103的频域资源与eMBB用户设备102的频域资源存在冲突且预占用的波束总量超过某小区同一时刻最大调度的波束总量阈值时，通过波束资源进行区分，大大提升无线资源的利用率，有效减少ULLC用户设备103下行业务抢占对eMBB用户设备102的影响，使某些与URLLC用户设备103占用的频域资源冲突的eMBB用户设备102可以不被抢占。
通常的，通过波束资源之间的隔离度以描述波束之间的同频干扰大小，波束资源之间的隔离度采用波束资源对应的波束向量之间的夹角表示，波束向量之间的夹角越大，表明隔离度越好，波束之间的同频干扰越小；繁殖，波束向量之间的夹角越小，表明隔离度越差，波束之间的同频干扰越大。
在线性代数中，空间向量a和空间向量b的夹角θ满足以下关系：
cosθ＝a×b/(|a||b|)。
如图1所示，假设某小区在同一时刻最大调度的波束总量阈值为4，小区波束模式如图1所示，波束资源1和波束资源4对应的波束向量夹角记为θ，其中，波束资源1和波束资源4的波束向量夹角大于预设的波束向量夹角阈值α，满足隔离度要求，能够通过波束资源进行区分；同理，波束资源1和波束资源5、波束资源1和波束资源6、以及波束资源1和波束资源7，均满足隔离度要求。同时，波束资源2和波束资源5、波束资源2和波束资源6、波束资源2和波束资源7、波束资源3和波束资源6、波束资源3和波束资源7、波束资源4和波束资源7的波束向量夹角均大于预设的波束向量夹角阈值α，均满足隔离度要求，能够通过波束资源进行区分。
下面结合附图及实施例对本示例实施方式进行详细说明。
首先，本公开实施例中提供了一种下行资源抢占方法，该方法可以由任意具备计算处理能力的电子设备执行。
图2示出本公开实施例中一种下行资源抢占方法流程图，如图2所示，本公开实施例中提供的下行资源抢占方法，包括如下步骤：
S202、获取超可靠和低延迟通信URLLC用户设备的待调度无线资源，其中，待调度无线资源包括URLLC用户设备所处的微时隙、预占用的下行波束资源和频域资源；
S204、在相同微时隙下，当URLLC用户设备的频域资源和增强的移动宽带eMBB用户设备的频域资源存在冲突时，确定预占用的波束总量；
在本实施例中，通过检测URLLC用户设备的频域资源和eMBB用户设备的频域资源是否存在重叠，从而判定URLLC用户设备的频域资源和eMBB用户设备的频域资源是否存在冲突。具体的，当两者存在重叠时，判定URLLC用户设备的频域资源和eMBB用户设备的频域资源存在冲突；若两者不存在重叠，则判定URLLC用户设 备的频域资源和eMBB用户设备的频域资源未存在冲突。
例如，如图6所示，在某一微时隙下，基站准备调度4个eMBB用户设备，分别为eMBB UE1～eMBB UE4，待调用的波束资源分别为波束1、波束2、波束4和波束7，URLLC用户设备的待调用波束资源为波束5，对于频域资源，URLLC用户设备的待调用频域资源与eMBB UE2的波束资源存在重叠，故URLLC用户设备的待调用频域资源与eMBB UE2的波束资源存在冲突，eMBB UE2存在被抢占的几率。
预占用的波束总量包括URLLC用户设备的待调度波束资源和eMBB用户设备的待调度波束资源的总和。在同一时刻某一小区最多能调度的波束总量阈值是固定的，当URLLC用户设备的频域资源和增强的移动宽带eMBB用户设备的频域资源存在冲突时，可通过预占用的波束总量与同一时刻某小区最多能调度的波束总量阈值之间的大小关系，进而确定eMBB用户设备的被抢占状态。
通常的，同一时刻某小区最多能调度的波束总量阈值可预先配置于基站的存储器内。
S206、根据所述预占用的波束总量与预设的波束总量阈值之间的关系，确认所述eMBB用户设备被抢占的状态，以调度所述URLLC用户设备的待调度无线资源。
本实施例中，eMBB用户设备和URLLC用户设备可以应用于两种通信场景。其中，eMBB用户设备可以提供更高带宽，例如超高清视频等大流量移动宽带业务；URLLC用户设备可以满足各种实时通讯需求，且可靠度更高，例如无人驾驶、工业自动化业务。具体而言，eMBB用户设备和URLLC用户设备可在同一基站侧实现，也可在不同基站侧实现。
本公开的实施例所提供的一种下行资源抢占方法，同时考虑了时域资源、频域资源、波束资源以及小区在同一时刻最大调度的业务波束总量对资源抢占的影响，有效减少URLLC用户设备下行资源抢占对eMBB用户设备的影响，使某些与URLLC用户设备占用的频域资源冲突的eMBB用户设备可以不被抢占，从而提高了资源的利用率。
在本公开的一个实施例中，如图3所示，所述S206根据预占用的波束总量与预设的波束总量阈值之间的关系，确认eMBB用户设备被抢占的状态，以调度URLLC用户设备的待调度无线资源，具体包括：
S302、判断预占用的波束总量是否超过预设的波束总量阈值；
S304、当预占用的波束总量超过预设的波束总量阈值时，取消与URLLC用户设备的频域资源存在冲突的eMBB用户设备的调度，并发送下行资源抢占指示，以调度URLLC用户设备的待调度无线资源。
具体的，如图6所示，某一微时隙下，基站准备调度的4个eMBB用户设备分别为eMBB UE1～eMBB UE4，各eMBB用户设备分别调用的波束资源的编号为：1、2、4、7，其中，eMBB UE1、eMBB UE3、eMBB UE4采用MU-MIMO配对，使用相同 的频域资源，通过不同波束资源隔离区分；eMBB UE2与eMBB UE1、eMBB UE3、eMBB UE4通过频域资源区分。此时，若插入突发的URLLC UE，其频域资源与eMBB UE2的频域资源冲突，预占用波束资源5。
可知，URLLC UE预占用的波束资源5与eMBB UE2的波束资源2的波束向量夹角大于预设的波束向量夹角阈值α，隔离度满足要求，因此，URLLC UE和eMBB UE2可以通过波束资源隔离区分。而eMBB UE已占用4个波束资源，已达到小区同一时刻调度波束资源的上限，故，为了完成URLLC UE的调度，同时，需要取消一个eMBB UE的无线资源的调度，此处，取消与所述URLLC UE的频域资源存在冲突的eMBB UE2所在波束资源的调度，即eMBB UE2的无线资源被抢占，波束资源2被取消调度，或者，取消与所述URLLC UE的波束资源隔离度最小的eMBB UE3所在波束资源的调度，即eMBB UE3的无线资源被抢占，波束资源4被取消调度。
在另一个实施例中，如图7所示，某一微时隙下，基站准备调度的4个eMBB用户设备分别为eMBB UE1～eMBB UE4，各eMBB用户设备分别调用的波束资源的编号为：1、2、4、7，其中，eMBB UE1、eMBB UE3、eMBB UE4采用MU-MIMO配对，使用相同的频域资源，通过不同波束资源隔离区分；eMBB UE2与eMBB UE1、eMBB UE3、eMBB UE4通过频域资源区分。此时，若插入突发的URLLC UE，其频域资源与eMBB UE2的频域资源冲突，预占用波束资源2，与eMBB UE2的波束资源相同。
由于预占用的波束总量已达到小区同一时刻调度波束资源的上限，故，为了完成URLLC UE的调度，需要取消与所述URLLC UE的波束资源相同的eMBB UE2所在波束资源的调度。
在本实施例中，如图3所示，所述方法还包括：
S306、当预占用的波束总量未超过预设的波束总量阈值时，判断获取到的URLLC用户设备的波束资源和eMBB用户设备的波束资源之间的波束向量夹角是否满足预设的波束隔离条件；
S308、若未满足，则取消与URLLC用户设备的频域资源冲突的eMBB用户设备的调度，并发送下行资源抢占指示，以调度URLLC用户设备的待调度无线资源。
具体的，如图8所示，某一微时隙下，基站准备调度的3个eMBB用户设备，分别为eMBB UE1～eMBB UE3，各eMBB用户设备分别调用的波束资源的编号为：1、2、4，其中，eMBB UE1和eMBB UE3采用MU-MIMO配对，使用相同的频域资源，通过不同波束资源隔离区分；eMBB UE2与eMBB UE1、eMBB UE3通过频域资源区分。此时，若插入突发的URLLC UE，其频域资源与eMBB UE1、eMBB UE3的频域资源冲突，预占用波束资源5。
可知，URLLC UE预占用的波束资源5与eMBB UE1的波束资源1的波束向量夹角大于预设的波束向量夹角阈值α，满足隔离度要求，因此，URLLC UE和eMBB UE1可以通过波束资源隔离区分。而波束资源5和波束资源4是相邻波束，两者之间的波 束向量夹角小于预设的波束向量夹角阈值α，不满足隔离度要求，故URLLC UE和eMBB UE3既不能通过频域资源区分，也无法通过波束资源隔离区分。因此，虽然eMBB UE占用的波束资源未达到小区同一时刻调度波束资源的上限，但是，由于eMBB UE3无法通过频域和波束区分，故，为了完成URLLC UE的调度，需要取消与所述URLLC UE的频域资源存在冲突的eMBB UE3所在波束资源的调度，即eMBB UE3的无线资源被抢占，波束资源4被取消调度。
在本公开的一个实施例中，如图3所示，所述方法还包括：
S3010、若波束向量夹角满足预设的波束隔离条件，则判定eMBB用户设备的无线资源未被抢占，直接调度URLLC用户设备的待调度无线资源。
具体的，如图9所示，某一微时隙下，基站准备调度的3个eMBB用户设备，分别为eMBB UE1～eMBB UE3，各eMBB用户设备分别调用的波束资源的编号为：1、2、4，其中，eMBB UE1和eMBB UE3采用MU-MIMO配对，使用相同的频域资源，通过不同波束资源隔离区分；eMBB UE2与eMBB UE1、eMBB UE3通过频域资源区分。此时，若插入突发的URLLC UE，其频域资源与eMBB UE2的频域资源冲突，预占用波束资源5。
可知，URLLC UE与eMBB UE1、eMBB UE3通过频域资源区分，而预占用的波束资源5与eMBB UE2的波束资源2的波束向量夹角大于预设的波束向量夹角阈值α，满足隔离度要求，因此，URLLC UE和eMBB UE2可以通过波束资源隔离区分。因此，预占用的波束总量未达到小区同一时刻调度波束资源的上限，故，无需取消eMBB UE的调度，即可同时完成完成URLLC UE和eMBB UE的无线资源调度。
本发明实施例提供的下行资源抢占方法，当URLLC用户设备的频域资源和eMBB用户设备的频域资源存在冲突时，根据预占用波束总量的情况，结合URLLC用户设备与eMBB用户设备的波束资源隔离区分，有效提升下行资源的利用率，从而保证了eMBB用户设备的业务性能，有效降低URLLC用户设备抢占对eMBB用户设备的影响。
在本公开的一个实施例中，如图4所示，所述方法还包括：
S402、若在相同微时隙下，URLLC用户设备的频域资源和eMBB用户设备的频域资源未存在冲突，则确定预占用的波束总量；
S404、根据预占用的波束总量与预设的波束总量阈值之间的关系，确认eMBB用户设备被抢占的状态，以调度URLLC用户设备的待调度无线资源。
本实施例中，虽然URLLC用户设备的频域资源与eMBB用户设备的频域资源未存在冲突，但是，若预占用的波束总量超过在同一时刻下某小区的最大调度波束总量阈值，仍需要取消一个eMBB用户设备所在波束资源的调度，以完成URLLC用户设备的待调度无线资源，只有当预占用的波束总量未超过预设的波束总量阈值时，方可完成对eMBB用户设备和URLLC用户设备的同时调度。
在本公开的一个实施例中，如图5所示，步骤S404根据预占用的波束总量与预设的波束总量阈值之间的关系，确认eMBB用户设备被抢占的状态，以调度URLLC用户设备的待调度无线资源，具体包括：
S502、判断预占用的波束总量是否超过预设的波束总量阈值；
S504、当预占用的波束总量超过预设的波束总量阈值时，取消频域资源与URLLC用户设备的频域资源最接近的eMBB用户设备的调度，并发送下行资源抢占指示，以调度URLLC用户设备的待调度无线资源。
具体的，如图10所示，某一微时隙下，基站准备调度的4个eMBB用户设备，分别为eMBB UE1～eMBB UE4，各eMBB用户设备分别调用的波束资源的编号为：1、2、4、7，其中，eMBB UE1、eMBB UE3、eMBB UE4采用MU-MIMO配对，使用相同的频域资源，通过不同波束资源隔离区分；eMBB UE2与eMBB UE1、eMBB UE3、eMBB UE4通过频域资源区分。此时，若插入突发的URLLC UE，其频域资源与各eMBB UE的频域资源未发生冲突，因此，可通过频域资源与eMBB UE1～eMBB UE4通过频域资源区分。
URLLC UE预占用波束资源5，然而，预占用的波束总量已超过某小区同一时刻调度波束资源的上限，新增波束调度的同时必须取消一个eMBB UE的调度。由于频率接近的eMBB UE的无线资源调度对URLLC UE的无线资源调度产生干扰的可能性最大，为了保证URLLC UE的无线资源调度的准确性，故取消与URLLC UE的频域资源最接近的eMBB UE2的调度，故，取消eMBB UE2所在波束资源2的调度，即eMBB UE2的无线资源被抢占。
在另一实施例中，如图11所示，某一微时隙下，基站准备调度的4个eMBB用户设备，分别为eMBB UE1～eMBB UE4，各eMBB用户设备分别调用的波束资源的编号为：1、2、4、7，其中，eMBB UE1、eMBB UE3、eMBB UE4采用MU-MIMO配对，使用相同的频域资源，通过不同波束资源隔离区分；eMBB UE2与eMBB UE1、eMBB UE3、eMBB UE4通过频域资源区分。此时，若插入突发的URLLC UE，其频域资源与各eMBB UE的频域资源未发生冲突，因此，可通过频域资源与eMBB UE1～eMBB UE4通过频域资源区分。URLLC UE预占用波束资源2，虽然其与eMBB UE2的波束资源2相同，但是URLLC UE的频域资源与eMBB UE2的频域资源不同，可通过频域资源进行区分，故，无需取消eMBB UE的调度，同时对eMBB UE和URLLC UE的调度即可。
在本公开的一个实施例中，如图5所示，所述方法还包括：
S506、当预占用的波束总量未超过预设的波束总量阈值时，判定eMBB用户设备的无线资源未被抢占，直接调度URLLC用户设备的待调度无线资源。
具体的，如图12所示，某一微时隙下，基站准备调度的3个eMBB用户设备，分别为eMBB UE1～eMBB UE3，各eMBB用户设备分别调用的波束资源的编号为：1、 2、4，其中，eMBB UE1、eMBB UE3采用MU-MIMO配对，使用相同的频域资源，通过不同波束资源隔离区分；eMBB UE2与eMBB UE1、eMBB UE3通过频域资源区分。此时，若插入突发的URLLC UE，其频域资源与各eMBB UE的频域资源未发生冲突，因此，可通过频域资源与eMBB UE1～eMBB UE3通过频域资源区分。
URLLC UE预占用波束资源5，预占用的波束总量未超过某小区同一时刻调度波束资源的上限，新增波束调度的无需取消一个eMBB UE的调度。故同时对URLLC UE的待调度无线资源和eMBB UE的无线资源进行调度。
本实施例提供的一种下行资源抢占方法，当URLLC用户设备的频域资源和eMBB用户设备的频域资源未存在冲突时，通过比较预占用的波束总量和在同一时刻下某小区的最大调度波束总量阈值之间的大小关系，以确定是否需要eMBB用户设备所在波束资源的调度，以完成URLLC用户设备的待调度无线资源，有效减少URLLC用户设备下行数据业务抢占对eMBB用户设备的影响，使某些与URLLC用户设备占用的频域资源冲突的eMBB用户设备可以不被抢占，从而提高了资源的利用率。
基于同一发明构思，本公开实施例中还提供了一种下行资源抢占装置，如下面的实施例所述。由于该装置实施例解决问题的原理与上述方法实施例相似，因此该装置实施例的实施可以参见上述方法实施例的实施，重复之处不再赘述。
