图1示出了可以应用本申请实施例技术方案的示例性系统架构的示意图。
如图1所示，系统架构可以包括用户设备101、用户设备102、用户设备103和基站104。其中，用户设备101、用户设备102和用户设备103可以是智能手机、平板电脑、便携式计算机、台式计算机等；用户设备101和用户设备102处于小区1中，用户设备102和用户设备103处于小区2中，且用户设备101、用户设备102和用户设备103构成了通信群组。
应该理解，图1中所示的用户设备和基站的数目仅仅是示意性的。根据实现需要，可以具有任意数目的用户设备和基站。
在本申请的一个实施例中，基站104(也可以是其它网络侧设备，如位于核心网或网络边缘的应用服务器)在接收到用户设备102通过上行信道发送的群组数据(该群组数据可以是发送至用户设备101和用户设备103的)后，可以获取到该群组数据需要发送到的目标小区(即小区1和小区2)，以及将该群组数据发送至该目标小区所采用的目标传输方式(如单播、组播或广播等)，进而可以基于确定的目标传输方式将该群组数据通过下行信道传输至目标小区，以供接收方设备(即用户设备101和用户设备103)进行接收。可见，本申请实施例的技术方案可以通过网络侧设备(如基站、应用服务器等)的辅助来实现群组通信机制，并且能够通过网络侧设备实现对所构建的设备群组的有效管控，提高了群组通信的可靠性。
以下对本申请实施例的技术方案的实现细节进行详细阐述：
图2示意性示出了根据本申请实施例所提供通信方法的流程图，该通信方法可以用于本申请实施例所提供的无线通信系统，该通信方法可以由网络侧设备来执行，比如可以由基站，或者位于核心网或网络边缘的应用服务器来执行。参照图2所示，该通信方法至少包括步骤S210至步骤S230，详细介绍如下：
在步骤S210中，接收发送方设备通过上行信道发送的群组数据。
在本申请的一个实施例中，发送方设备可以是作为用户设备(User Equipment，UE)的智能手机、平板电脑、便携式计算机、台式计算机等。发送方设备在发送群组数据时的上行信道可以是5G通信系统中的上行信道，发送方设备发送的群组数据是需要发送至与发送方设备处于同一群组中的其他 用户设备的数据。其中，与发送方设备处于同一群组的用户设备可以位于同一个小区内，也可以位于不同的小区内，即各个群组中用户设备不受移动通信的小区规划限定。同时，不同群组中的发送方设备可以由网络侧设备指定或由各个用户设备主动决定是否作为发送方设备。
在步骤S220中，获取所述群组数据需要发送到的目标小区，以及将所述群组数据发送至所述目标小区所采用的目标传输方式。
在本申请的一个实施例中，目标传输方式包括：单播、广播、组播。以下对步骤S220的具体实现方式进行详细阐述：
实现方式一：
在本申请的一个实施例中，可以获取发送方设备发送的指示消息，然后根据该指示消息确定所述目标小区和所述目标传输方式。即该实施例的技术方案是通过发送方设备发送的指示消息来确定群组数据需要发送的目标小区和所采用的传输方式。
在本申请的一个实施例中，可以获取发送方设备针对不同数据报文发送的指示消息，以确定不同数据报文分别对应的目标传输方式。即发送方设备可以基于每个数据报文来指示传输方式，提高了群组数据发送的灵活性。
在本申请的一个实施例中，可以从发送方设备发送的数据报文的指定报文头中获取上述的指示消息。其中，若发送方设备发送的数据报文的Ethernet报文头在发送前被压缩，那么数据报文中的组播或多播地址会被去除，因此可以根据数据报文的压缩情况，选择未被压缩的其它报文头(如SDAP头、PDCP头或RLC头等)中添加上述的指示消息。
在本申请的一个实施例中，指示消息在指示具体的传输方式时，可以通过两个比特位来表示，即使用相应的报文头中的两个比特位来表示传输方式，比如通过“00”表示广播、“01”表示单播、“11”表示组播。
在本申请的一个实施例中，网络侧设备还可以获取各个用户设备所在的小区信息，然后将各个用户设备所在的小区信息发送至发送方设备，以供发送方设备根据接收方设备所在的小区信息确定所述群组数据需要发送到的目标小区。
在本申请的一个实施例中，网络侧设备在获取各个用户设备所在的小区信 息时，可以获取各个用户设备所在的位置信息，然后根据各个用户设备所在的位置信息和各个小区的覆盖范围，确定各个用户设备所在的小区信息。
在本申请的一个实施例中，网络侧设备在获取各个用户设备所在的小区信息时，可以获取其它网络侧设备提供的各个用户设备所在的小区信息。比如应用服务器可以获取基站或核心网网元提供的各个用户设备所在的小区信息。
在本申请的一个实施例中，网络侧设备在获取各个用户设备所在的小区信息时，可以接收各个用户设备上报的小区信息。
实现方式二：
在本申请的一个实施例中，可以根据上述的群组数据在传输时的承载方式，确定所述目标小区和所述目标传输方式。
可选地，在本申请的一个实施例中，可以确定群组数据在传输时所采用的数据无线承载(Data Radio Bearer，DRB)，然后将预配置的与该群组数据在传输时所采用的数据无线承载相对应的小区及传输方式作为所述目标小区和所述目标传输方式。即该实施例中可以根据群组数据在传输时的数据无线承载来确定群组数据所要发送到的目标小区和所采用的目标传输方式。
在本申请的一个实施例中，还可以确定群组数据在传输时所在的网络切片，然后将预配置的与该群组数据在传输时所在的网络切片相对应的小区及传输方式作为所述目标小区和所述目标传输方式。即该实施例中可以根据群组数据在传输时所在的网络切片来确定群组数据所要发送到的目标小区和所采用的目标传输方式。
在本申请的一个实施例中，对于实现方式二的技术方案，可以在群组数据的数据报文头中携带群组信息，以便于接收方设备根据该群组信息确定该群组数据是否为发送至自身的数据。
实现方式三：
在本申请的一个实施例中，若不同类型的群组数据在传输时采用相同的数据无线承载，则将所述不同类型的群组数据发送至目标设备，以获取该目标设备确定的不同类型的群组数据要发送到的目标小区，以及将所述不同类型的群组数据发送至目标小区所采用的目标传输方式。即该实施例的技术方案使得在不同类型的群组数据混用在一个DRB上时，可以基于目标设备(如边缘计算设 备或应用服务器等)的辅助来确定不同类型的群组数据要发送到的目标小区及所采用的目标传输方式。
继续参照图2所示，在步骤S230中，基于所述目标传输方式将所述群组数据通过下行信道传输至所述目标小区，以供接收方设备进行接收。
在本申请的一个实施例中，接收方设备可以是与发送方设备处于同一通信群组中的设备。其中，发送方设备与接收方设备可以位于同一个小区内，也可以位于不同的小区内，当接收方设备与发送方设备位于同一个小区内时，目标小区即为发送方设备所在的小区。
图2所示实施例的技术方案使得在无线通信系统中，可以通过网络侧设备的辅助来实现群组通信机制，并且能够通过网络侧设备实现对所构建的设备群组的有效管控，提高了群组通信的可靠性。
以下以在5G通信系统中进行群组通信为例，对本申请实施例的技术方案进行详细阐述：
在本申请的一个实施例中，如图3所示，用户设备301和用户设备302属于一个5G LAN 1，用户设备302、用户设备303和用户设备304属于另一个5G LAN 2。其中，5G LAN 1中的所有用户设备(即用户设备301和用户设备302)都位于同一个小区内，5G LAN 2中的用户设备位于不同的小区内(即用户设备303和用户设备304所在的小区与用户设备302所在的小区不同)。对于5G LAN中的所有用户设备位于同一个小区内的情况，用户设备之间传输的群组数据在发送时不需要经过基站之间的接口进行转发；而对于5G LAN中的用户设备位于不同小区的情况，则用户设备之间传输的群组数据需要进行基站之间的转发，而基站之间转发的时延会影响数据传输的时延。当确定群组数据是否需要在基站之间转发时，需要判断5G LAN设备是否位于同一小区内，即网络侧设备需要维护各个用户设备的位置信息，进而可以决定将群组数据在哪些小区/扇区甚至波束集合上进行发送。其中，图3中所示的AMF即为接入和移动性功能实体(Access and Mobility Function)，UPF即为用户端口功能实体(User Port Function)，SMF即为业务管理点(Service Management Point)，NEF即为网元功能(Network Element Function)。
在本申请的一个实施例中，维护5G LAN设备的位置信息的网络侧设备可 以是图3中所示的应用服务器(该应用服务器可以是5G LAN应用服务器)，也可以是基站或者其他网元(如SMF等)。5G LAN设备的位置信息可以是承载5G LAN的小区或小区集合，也可以是承载5G LAN的小区的扇区或者波束集合。
在本申请的实施例中，收集和维护5G LAN设备的位置信息的方案可以包括如下实施例：
收集和维护5G LAN设备位置信息的实施例1：
网络侧设备基于5G LAN设备的物理位置来确定。具体地，网络侧设备可以获取每个5G LAN设备的具体物理位置，然后根据小区的覆盖数据和该具体物理地址来确定5G LAN设备所在的小区信息。该实施例的技术方案适合于5G小区部署较简单的情况，如果多小区临近部署，则实际的小区覆盖可能受到不同基站的功率和干扰因素影响会导致覆盖范围不规则，进而会影响确定的5G LAN设备所在小区信息缺乏准确性。
收集和维护5G LAN设备位置信息的实施例2：
基于网络能力开放来确定5G LAN设备的位置信息。具体地，网络侧的部分网元(如基站或者核心网网元)可以将终端的上下文信息开放给5G LAN服务器，该实施例的技术方案需要借助于5G网络能力的开放。
收集和维护5G LAN设备位置信息的实施例3：
基于终端的应用层汇报来确定5G LAN设备的位置信息。具体地，终端可以在应用层把5G LAN设备所在的小区信息发送给网络侧设备，如发送给5G LAN应用服务器。
在本申请的一个实施例中，当5G LAN设备需要发送群组数据时，可以将群组数据作为上行数据发送给网络侧设备(如基站或者与基站共址的功能实体如边缘计算实体等，以下以基站为例进行说明)，基站可以根据自身功能决定是由自身进行处理，还是进一步转发给5G LAN应用服务器进行处理。其中，基站决定由自身进行处理可以有如下两个实施例：
实施例1：
在本申请的一个实施例中，发送方设备在向网络侧设备发送群组数据时，需要向基站指示群组数据的接收方设备所在的小区(如是否与发送方设备在同 一小区)，以及在传输群组数据时是采用单播、广播还是组播的方式进行下行发送。该实施例的技术方案的实现前提是发送方设备的应用层知晓接收方设备(或接收方群组)所处的小区位置，比如网络侧设备可以事先将收集和维护的设备位置信息发送给发送方设备。
在本申请的一个实施例中，设备向基站指示的具体信息可以在相应的数据报文中进行体现。具体地，可以依据数据报文的压缩情况，将需要引入的指示信息比特添加到报文头中，如添加至IP头、PDCP头或者RLC报文头中。更具体地，如图4所示的5G LAN用户面协议栈，若发送方设备发送的数据报文的Ethernet报文头在发送前被压缩，那么数据报文中的组播或多播地址会被去除，因此可以根据数据报文的压缩情况，选择未被压缩的其它报文头(如SDAP头、PDCP头或RLC头等，若IP头未被压缩，则也可以将指示信息添加至IP头中)中插入比特指示。图4中所示的MAC即为媒体介入控制层(Media Access Control)；PHY即为端口物理层(Port Physical Layer)；GTP-U即为GPRS通道协议-用户面(GPRS Tunnel Protocol User Plane)；UDP即为用户数据报协议(User Datagram Protocol)；Xn接口即为基站gNB之间的接口；NG接口即为基站gNB与5G核心网之间的接口。需要说明的是，报文头压缩后的一些空中接口协议栈会在发送端被去掉而在接收端被恢复。
在本申请的一个实施例中，设备向基站指示的具体信息也可以在控制面配置的UE上下文中进行体现。
在本申请的一个实施例中，设备在进行指示时，可以针对每个数据报文确定发送方式，即设备在5G LAN群组里可以针对数据报文进行单播或者多播传输，而不依赖于数据报文头中的地址指示。
实施例2：
在本申请的一个实施例中，发送方设备在向网络侧设备(如基站)发送群组数据时不向基站指示接收方设备所在的小区，以及在传输群组数据时是采用单播、广播还是组播的方式进行下行发送，而由基站根据网络配置的上下文来执行。
在本申请的一个实施例中，网络侧设备可以维护转发表，以通过该转发表来确定5G LAN数据的发送位置及发送方式。具体地，如表1所示，如果不同的 5G LAN数据在终端侧基于DRB区分，则可以按DRB ID配置转发表。如DRB1的数据全部在本小区(即发送方设备所在的小区)下行进行广播；DRB 2的数据在本小区下行单播并转发到某个邻小区。
  本小区下行发送方式 是否转发到其他小区？
DRB1 广播 否
DRB2 单播 是
…… …… ……
表1
在本申请的另一个实施例中，如表2所示，如果不同的5G LAN数据可能属于不同的网络切片，则可以按照网络切片的ID(如S-NSSAI，即Single Network Slice Selection Assistance Information)来配置转发表。如表2所示，网络切片1的数据全部在本小区(即发送方设备所在的小区)下行进行广播；网络切片2的数据在本小区下行单播并转发到某个邻小区。
  本小区下行发送方式 是否转发到其他小区？
网络切片1 广播 否
网络切片2 单播 是
…… …… ……
表2
需要说明的是，实施例2的技术方案使得网络侧设备无须依赖于5G LAN设备的指示，但每个数据报文中需要携带5G LAN的组信息(如单播地址、组播地址或广播地址)，以便接收方设备根据组信息决定某个数据包是否是发给自己的。
在本申请的一个实施例中，如果基站不能确定将群组数据传输到哪个小区，则可以将数据传输给5G LAN应用服务器(或网络侧的边缘计算设备)，由5G LAN应用服务器决定将群组数据通过下行方式发往哪个或者哪些小区。具体地，比如若不同的5G LAN数据混用在一个DRB上，无法在接入层(Access Stratum，AS)进行区分，那么基站可以将5G LAN数据发送至5G LAN应用服务器，以在IP层以上实现5G LAN数据的转发，即在IP层以上确定5G LAN数据 需要转发至哪个小区或哪些小区，以及转发时是通过单播、组播还是广播的方式进行发送。
在本申请的一个实施例中，上述实施例中的组播和广播可以是基于单播实现的(即通过N次下行传输向N个目标终端进行发送)，也可以是基于多媒体广播多播业务(Multimedia Broadcast Multicast Service，MBMS)技术实现的，还可以是基于单小区点对多点(Single Cell-Point to Multi-point，SC-PTM)技术或者其他5G中引入的新的广播机制来实现的。
本申请上述实施例的技术方案适用于未来工厂环境下使用基于5G的空中接口来高可靠传输低时延地传输工业控制设备之间地数据包，如IP包或者non-IP包，以及Ethernet包等，满足了工业互联网(Industrial Internet of Things，IIoT)对低时延和可靠性的要求。并且本申请实施例的技术方案可以集成于工业控制设备，也可以独立部署。
本申请上述实施例以在5G通信系统中进行群组通信为例进行了阐述，需要说明的是，本申请实施例的技术方案同样适用于其他的无线通信系统。
以下介绍本申请的装置实施例，可以用于执行本申请上述实施例中的用于无线通信系统的通信方法。对于本申请装置实施例中未披露的细节，请参照本申请上述的用于无线通信系统的通信方法的实施例。
