In the latest version of 3GPP (3rd Generation Partnership Project), Sidelink resource allocation based on air interface assistance and PC5 interface management is regarded as the focus of the next research, which helps to meet the requirements of V2X in NR systems. The requirements for communication performance such as delay and reliability are of great significance to the communication scenarios in which users who can only conduct V2X communication through Sidelink independently select the resource mode.

技术领域
本申请涉及通信领域,尤其涉及一种信息发送的方法及装置。
背景技术
Sidelink(侧行链路)连接技术,即终端设备之间可以利用无线资源直接进行通信,是蜂窝物联网技术的一个重要的分支,最早是在D2D(Device to Device Communication,物与物通信技术)的应用场景下引入的。该技术的存在为物联网、车联网等应用创造了一个广阔的前景,颠覆了以往传统的蜂窝网络的通信架构和运营。在Sidelink技术中,资源的分配分为两种方式,一种是基于基站的资源分配方式,一种是终端自主选择的资源分配方式。在终端自主选择的资源分配方式中,由于资源的选择没有集中控制分配,因此存在资源冲突的概率。如何合理有效的进行资源的竞争一直是一个重要的研究课题。
发明内容
本申请实施例提供了一种信息发送的方法及装置,可以使得在Sidelink技术中组成员上报第一信息给组头,组头参考所接收到的第一信息确定侧行链路通信的资源,并将该侧行链路通信的资源发送给组成员,从而降低本组设备进行侧行链路通信时发生资源冲突的概率,提升整个组通信的性能。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明实施方式作进一步详细描述。
在本文中提及的“多个”是指两个或两个以上。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
随着无线通信技术的发展,移动通信网络逐渐向5G NR(New Radio,新空口)系统演进。在5G NR系统中,也引入了Sidelink(侧行链路)技术,即终端设备之间可以利用无线资源直接进行通信。如图1所示,侧行链路(sidelink)不同于终端设备和基站之间的上行链路(uplink)和下行链路(downlink),sidelink指的是终端设备和终端设备之间的链路,对应着PC5接口。
与4G LTE(Long Term Evolution,长期演进)系统中的Sidelink技术类似,上述NR系统的Sidelink技术可以应用于V2X(Vehicle to Everything,车联网)等应用场景中。NR系统的Sidelink的物理信道主要由PSCCH(Physical Sidelink Control Channel,物理Sidelink控制信道)、PSSCH(Physical Sidelink Shared Channel,物理Sidelink共享信道),PSBCH(Physical Sidelink Broadcast Channel,物理Sidelink广播信道)和PSFCH(Physical Sidelink Feedback Channel,物理Sidelink反馈信道)组成,其中前三种物理信道在LTE系统的Sidelink中已经存在,PSFCH是NR系统的Sidelink技术为了支持HARQ(Hybrid Automatic Repeat Request,混合自动重传请求)传输新引入的物理信道。PSSCH信道主要完成Sidelink数据信息的传输; PSCCH主要完成Sidelink控制信息的传输,即用来传输Sidelink控制指示(Sidelink Control Information,SCI)消息的。另外,还有两个同步信号:主Sidelink同步信号(Primary Sidelink Synchronization Signal,PSSS)和次Sidelink同步信号(Secondary Sidelink Synchronization Signal)。
Sidelink最早是在LTE系统中引入的,主要应用于D2D(Device to Device Communication,物与物通信技术)技术。最主要的目的是为了保证公共安全信息的有效通信(Public Safety Communication)。后来在LTE系统中引入了V2X(Vehicle to Everything,车联网)的概念,Sidelink也作为V2X标准化的一部分。Sidelink被定义为一种通过PC5接口实现终端设备之间的近距离服务直接通信的通信模式。在3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)最新版本中,基于空中接口辅助和PC5接口管理的Sidelink资源分配被视为下一个研究的重点,该研究有助于满足NR系统中V2X对时延、可靠性等通信性能的需求,且对只能通过Sidelink进行V2X通信的用户自主选择资源模式下的通信场景意义重大。
Sidelink的通信过程如图2所示,分为同步和通信两大部分。在同步过程中为了使得所有的终端设备都进入同步状态,目前有两种Sidelink同步流程的类型:基于GNSS(Global Navigation Satellite System,全球导航卫星系统)的同步流程和基于基站的同步流程。在通信过程中,资源的分配分为两种方式,图3A为基于基站的资源分配方式,在该种资源分配方式中,基站和终端设备之间存在着控制链路;图3B为终端自主选择的资源分配方式,在该种资源分配方式中,基站和终端设备之间不存在控制链路。
图3C给出了基于基站的资源分配方式的具体流程,当终端1需要发送数据时,发送资源请求到基站,基站接收到该资源请求后,通过DCI(Downlink Control Indicator,下行控制指示)将分配的资源发送给终端1。终端1接收到该DCI消息后,使用DCI消息中指示的资源将数据发送给终端2。从上述流程中可以看出在基于基站的资源分配方式中,终端的Sidelink资源需要基站进行集中分配,因此图3C所示的资源分配方式一般不会产生资源的冲突。
图3D给出了终端自主选择资源的分配方式的具体流程,当终端1需要发送数据时,终端1首先进行资源感知(Resource Sensing),具体的,终端1对资源池中的所有资源进行测量,然后从资源池中选择一组资源进行数据的发送。其中资源池的配置分为两种场景,一种是终端在基站网络覆盖范围内,资源池的配置可以从基站的系统消息中获取;一种是终端不在基站网络覆盖范围内,资源池的配置是预配置的。从上述流程中可以看出在终端自主选择的资源分配方式中,终端完全是自主的进行资源的选择,因此图3D所示的资源分配方式会产生资源的冲突,但是由于终端无需向基站申请资源,因此节省了信令的开销,可以降低数据传输的时延。另外终端自主选择的资源分配方式也适用于终端不在基站网络覆盖范围内,或者基站网络覆盖不佳的场景。
Sidelink技术的应用场景十分广阔,典型的应用场景包括家庭场景、会议室场景、组队游戏场景,车辆编队场景等。其中每一种应用场景中都包含了多个终端。例如在家庭场景中包含有手机、电视、PC、平板、音响、手环、耳机等终端设备;在会议室场景中包含有大屏、PC、手机、平板等终端设备;组队游戏场景中包含有多个游戏终端等;车辆编队场景中包含有多个行驶中的车辆、行人以及路边单元RSU。图3E示出了Sidelink技术中典型的家庭场景30,包括手机31、PC32、电视33、音箱34、平板35、耳机36、手环37,各设备之间可以通过Sidelink进行直接通信。图3F示出了Sidelink技术中典型的车辆编队场景,包括行人终端设备311、车辆312、路边单元RSU313、车辆314、基站316,各设备之间可以进行相互通信。车辆312和车辆314之间的通信叫做V2V(Vehicle to Vehicle),车辆314和路边单元RSU313之间的通信叫做V2I(Vehicle to Infrastructure),车辆314和行人终端设备311之间的通信叫做V2P(Vehicle to Pedestrian),车辆314和基站316之间的通信叫做V2N(Vehicle to Network)。
基于以上典型的应用场景,在Sidelink技术中,以组(Group)为单位运行的机制成为了主要研究的对象,其中组也称为通信组。以组为单位的运行机制拥有很多优点。具体的,在重载场景下,如果用户设备全部自主竞争资源,则产生资源冲突碰撞的概率会很高。如果存在一个组头来统筹资源的分配,则可以极大地降低资源冲突碰撞的概率。在组间大颗粒度地协商资源,组内的组头统一进行资源的分配,这样可以提高资源使用的效率。另外由于减少了与基站的信息交互,因此可以降低空口的时延。
图4A给出了本申请实施例的应用场景,在该场景中,多个终端组成组的形式来加强通信效率。其中终端10为组头,组头还可以称为Group Header或者组头终端或者组头设备,组头可以充当部分基站的角色来统筹协调整个组的管理。终端是一种向用户提供语音和/或数据连通性的设备,例如,具有无线连接功能的手持式设备、车载设备等。终端也可以称为用户设备(User Equipment,UE)、接入终端(Access Terminal)、用户单元(User Unit)、用户站(User Station)、移动站(Mobile Station)、移动台(Mobile)、远方站(Remote Station)、远程终端(Remote Terminal)、移动设备(Mobile Equipment)、用户终端(User Terminal)、无线通信设备(Wireless Telecom Equipment)、用户代理(User Agent)、用户装备(User Equipment)或用户装置。终端可以是无线局域网(Wireless Local Area Networks,WLAN)中的站点(Station,STA),可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信系统(例如,第五代(Fifth-Generation,5G)通信网络)中的终端或者未来演进的公共陆地移动网络(Public Land Mobile  Network,PLMN)网络中的终端等。其中,5G还可以被称为新空口(New Radio,NR)。本申请一种可能的应用的场景中终端为经常工作在地面的终端,例如车载设备。在本申请中,为了便于叙述,部署在上述设备中的芯片,或者芯片也可以称为终端。
作为示例,在本申请实施例中,该终端还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能首饰等。
在图4A中充当组头的终端10,从产品形态上来看,也是终端的一种,只是具备了部分基站的能力,即具有中心控制功能并且能够配置资源给其他的终端。图4A中除了充当组头的终端10外,其他的终端为组成员,组成员还可以称为Group Member或者组成员终端或者组成员设备。
在Sidelink技术中,组机制的运转需要一套完整的流程机制,其中关键的流程和技术包括:组的建立、组头的选择、组的维护,组间的资源竞争以及组内的资源分配等。
在一种可能的实施方式中,终端可以接受用户的设置来打开Sidelink的组功能,该功能属于终端的第三方应用或者终端的系统应用,如图4B所示,在终端的Sidelink的设置页面401上,用户可以通过打开Sidelink Group的开关402来开启组的功能。如图4C所示,终端接收用户的操作,打开Sidelink Group的开关,此时终端发现周围存在Group1和Group2两个组,终端可以接受用户的选择加入某一个组,也可以由终端自主选择加入某一个组。这样可以使得用户选择性的开启组功能,以及选择性的加入某一个组,增强了终端的安全性和用户的体验。
本申请实施例主要涉及Sidelink技术中的组间的资源竞争的问题。在利用组机制的Sidelink技术中,每一个组的资源可以以组为单位进行资源的竞争,也可以以每个终端设备为单位进行独立的资源的竞争。在以组为单位的竞争模式中,组间的资源可以相互正交,也可以部分重叠。组间的资源需要通过组头为整个组竞争得到。当两个组头距离较近时,选择重叠的资源会使得信号在该重叠资源上干扰较大,因此两个距离较近的组头会避免选择重合的资源来提高信号解调成功的概率。相反,两个距离较远的组头会尽量选择重合的资源提升资源的利用率。因此组头所处的位置不同,会导致竞争得到的资源结果相差较大,有些资源对该组中的组成员来说并不一定适合。
如图5所示,图中有三个组,分别为Group A、Group B-1以及Group B-2。 其中Group B-1中的组头距离Group A较远,因此Group B-1中的组头在竞争资源时,可能认为Group A对Group B-1的干扰很小,因此选择与Group A部分交叠或者完全重叠的资源。而Group B-1中的左下角的组成员与Group A距离很近,如果使用了与Group A完全重叠的资源则会产生严重的干扰,导致这些用户设备的性能很差。同样Group B-2中的组头距离Group A较近,因此Group B-2中的组头在竞争资源时,可能认为Group A对Group B-2的干扰很大,因此可能选择与Group A完全错开的资源。而Group B-2的右下角的组成员与Group A距离很远,因此可以使用和Group A部分重叠的资源,这样会造成资源利用率不高。
为了解决上述的问题,本申请实施例提供了一种信息发送的方法用来辅助组头进行资源的选择。资源的选择最终是为了组成员之间的通信,因此获取组成员的反馈是保障资源选择性能的一个重要手段。具体的,组成员终端设备测量信道上资源的占用情况,并将测量结果上报给组头。组头基于自己的测量结果并结合组成员上报的结果,统一决策最终侧行链路通信的资源并将该侧行链路通信的资源发送给所有的组成员,从而保障组通信的性能。
本申请实施例提供的一种信息发送的方法的总的流程如图6所示,该方法应用于无线通信系统,该无线通信系统包括第一终端和第二终端,其中第一终端为组头,第二终端为组成员,第二终端为一个或多个,该方法主要包括:
S601,第一终端向第二终端发送第一指示消息,该第一指示消息用于指示第二终端上报第一信息。具体的第一指示消息包括第一信息上报时机的指示,待测量资源集合的指示,上报内容类型的指示,测量门限的指示,第一信息的发送机制的指示等。
S602,第二终端向第一终端上报第一信息。第一信息用于指示信道资源的信道状态信息,其中信道资源是第一终端指示第二终端测量的资源。具体的,第二终端根据第一终端发送的第一指示消息进行资源的测量,测量完成后周期性或者非周期性的将第一信息上报给第一终端。第一信息包括第二终端收集的相应待测量资源的干扰信息,该干扰信息包括例如临近终端对待测量资源的干扰信息,临近终端可以包括本组的终端或临近组的终端,当第二终端收集到临近组的终端对相应待测量资源的干扰信息,并上报给第一终端,第一终端可以参考该干扰信息进行资源的选择,以避免临近组对本组资源传输的干扰,进而提高传输效率。当然,干扰信息也包括非临近终端对待测量资源的干扰信息。在一种可选的实施方式中,第二终端在对待测量资源进行测量时,只测量非本组的终端设备对待测量资源的干扰,即第一信息只包括其他组的终端设备对待测量资源的干扰。可选的,第二终端在收到第一终端的第一指示消息之前已经完成了资源的测量,当收到第一终端发送的第一指示消息时直接根据指示上报第一信息。
S603,第一终端发送第二指示消息给第二终端,该第二指示消息用于指示第一资源集合的信息,其中,第一资源集合是第一终端参考接收到的第一信息确定 的,第一资源集合中的资源为侧行链路通信的资源。具体的第一终端根据的第二终端上报的第一信息,并结合第二信息最终确定第一资源集合,第二信息为第一终端测量得到的集合,接着第一终端通过第二指示消息将第一资源集合发送给本组第二终端。
结合图4A,图7A示出了本申请实施例提供的一种信息发送的方法,该方法应用于无线通信系统,该无线通信系统包括第一终端和第二终端,其中第一终端为组头,第二终端为组成员,第二终端为一个或多个,该方法是第一类状态信息的上报,包括:
S701,第一终端发送第一指示消息给第二终端,第一指示消息用于指示第二终端上报第一信息。第一信息用于指示信道资源的信道状态信息,其中信道资源是第一终端指示第二终端测量的资源。
在一种可选的实施方式中,当第一终端被选中成为组头后,第一终端给第二终端发送第一指示消息,指示第二终端上报第一信息。
在一种可选的实施方式中,当第一终端检测到新增第二终端后,即检测到新增组成员设备,第一终端向该新增的第二终端或者所有的第二终端发送第一指示消息,指示新增的第二终端或者所有的第二终端上报第一信息。
具体的第一指示消息中包括以下几种指示信息:
1、上报时机类型的指示,第一终端在给第二终端发送第一指示消息时,需要进行相应的上报时机的配置。上报时机的配置可以分为周期配置和非周期配置两种。
周期配置是指第二终端一旦接收到该配置,会以固定的周期进行相应的测量并将第一信息上报给第一终端。周期可以选择1ms、2ms、5ms、10ms、20ms、40ms、80ms、160ms、320ms等。
在一种可选的实施方式中,第一终端可以给第二终端分别配置测量周期和上报周期,具体的测量周期和上报周期可以一样,也可以不一样。
在一种可选的实施方式中,第一终端测量第二终端的移动速度,或者第二终端将移动速度上报给第一终端,第一终端根据第二终端的移动速度配置不同的周期。
非周期配置是指第一终端根据需求触发指示第二终端进行第一信息的上报,第二终端在收到指示后在某个时刻进行第一信息的上报。
在一种可选的实施方式中,第一终端在指示信息中动态的指示第二终端在某个时刻进行第一信息的上报。
在一种可选的实施方式中,第二终端在接收到第一终端发送的指示信息时,在缺省的时长后进行第一信息的上报。
在一种可选的实施方式中,第一终端测量和第二终端之间的距离,当该距离的变化达到第一距离门限时,第一终端向该第二终端发送第一信息上报的指示触发该第二终端进行非周期性的第一信息的上报。
2、待测量资源集合的指示,第一终端给第二终端配置待测量资源集合,第二终端接收到待测量资源集合的指示后,对待测量资源集合中的待测量资源进行测量和上报。待测量资源集合用于指示第二终端测量的信道资源的位置。具体的,待测量资源集合是第一终端的资源池的全集或者子集,其中资源池的配置分为两种场景,一种是第一终端在基站网络覆盖范围内,则资源池的配置从基站的系统消息中获取;一种是第一终端不在基站网络覆盖范围内,则资源池的配置是预配置的。
在一种可选的实施方式中,第一终端根据历史资源使用的情况,将资源池的全集或者子集作为待测量资源集合指示给第二终端。例如根据统计,资源池中的某些资源的误码率很高,则不将这些资源作为待测量资源集合。
在一种可选的实施方式中,第二终端提前将终端的能力上报给第一终端,第一终端根据第二终端的性能差异配置不同的待测量资源集合。例如给低性能的第二终端配置的待测量资源集合中的资源少一些,给高性能的第二终端配置的待测量资源集合中的资源多一些。
3、上报内容类型的指示,在该实施例中上报内容类型为第一类状态信息,第一类状态信息用于指示信道资源的信道质量是否满足第一阈值门限。具体的信道质量包括RSRP(Reference Signal Receiving Power,参考信号接收功率)、SINR(Signal to Interference plus Noise Ratio,信号与干扰加噪声比)或者RSRQ(Reference Signal Receiving Quality,参考信号接收质量)等。
在一种可选的实施方式中,第二终端可以在满足测量门限的资源上报1,不满足测量门限的资源上报0。如图7B所示,假设第一终端配置的待测量资源集合为S,包括5个测量资源。资源1和资源5的测量值低于测量门限,第二终端则在对应的资源上置1;其余资源的测量值不低于测量门限,第二终端则在对应的资源上置0。
4、测量门限的指示,即第一阈值门限的指示。针对该实施例的上报内容类型,第一终端可以指示该上报内容类型中组成员设备的测量门限,也可以缺省,第二终端使用默认值。在该实施例中,当上报内容类型的指示中的干扰为RSRP时,则测量门限包括-60dBm、-65dBm、-70dBm、-75dBm、-80dBm、-85dBm等。
5、第一信息的发送机制的指示。在一种可选的实施方式中,第一终端配置的是基于预留资源的第一信息的上报指示,第二终端收到该指示后,在预留资源上上报第一信息,这样可以保证第一终端在预计时间内收到所有的第二终端上报的第一信息。
在一种可选的实施方式中,第一终端配置的是基于自由选择资源的第一信息的上报指示,第二终端收到该指示后,需要进行资源的感知,当感知到合适的资源时将第一信息上报给第一终端。在这种上报的方式中,由于通过感知获取合适的资源存在资源冲突的可能,因此第一终端需要启动一个定时器来判断是否及时收到了第二终端上报的第一信息。
第一终端可以将以上几种指示信息打包成一条消息发送给第二终端,也可以分几条消息发送给第二终端,本申请实施例不做限制。第一终端可以通过RRC(Radio Resource Control,无线资源控制)消息、MCE(MAC Control Element,MAC控制单元)消息、SCI(Sidelink Control Indicator,Sidelink控制指示)消息等消息将第一指示消息发送给第二终端,本申请实施例对承载消息的类型不做限制。第一终端通过感知获取合适的资源后将第一指示消息发送给第二终端,由于通过感知获取合适的资源存在资源冲突的可能,第一终端可以采用多次重传的方式提高发送第一指示消息成功的概率。
S702,第一终端和第二终端对资源进行测量。具体的,第二终端根据第一终端指示的待测量资源集合中的待测量资源进行测量。第一终端可以对资源池中所有的资源进行测量,也可以根据给所有第二终端配置的待测量资源集合的并集进行测量。在本实施例中,当上报内容类型的指示中的干扰为RSRP时,第二终端以及第一终端对每一个资源进行RSRP的测量。如果该第二终端为无感知能力的终端设备或者部分感知能力的终端设备,那么该第二终端可以通过接收周围第二终端分享的测量信息的方式来获取测量结果。无感知能力的终端设备一般为对功耗要求比较高的终端设备,比如手机、物联网移动设备等。部分感知能力的终端设备一般为性能比较低的终端设备,无法对资源进行全量的感知,比如路边单元的终端设备等。
在一种可选的实施方式中,第一终端和第二终端在对待测量资源进行测量时,不区分对待测量资源的干扰是来自于本组的终端设备还是非本组的终端设备,即测量的是所有的终端设备对待测量资源的干扰。
在一种可选的实施方式中,第一终端和第二终端在对待测量资源进行测量时,只测量非本组的终端设备对待测量资源的干扰。可选的,可以利用零功率的CSI(Channel State Information)参考信号的机制来获得非本组的终端设备对待测量资源的干扰。具体的,零功率的CSI参考信号的时频位置的设计是和组相关联的,即组内的终端设备使用的零功率的CSI参考信号的时频位置是一致的,而不同组的零功率的CSI参考信号的时频位置是不同的。由于本组的终端设备在对应的零功率CSI参考信号的时频资源上不发射功率,这样本组的终端设备在本组对应的零功率CSI参考信号的时频资源上测量得到的信号能量即为非本组的终端设备产生的干扰。可选的,可以利用本组广播的SCI(Sidelink Control Indicator)的机制获得非本组的终端设备对待测量资源的干扰。具体的,对于存在数据传输的待测量资源,组内的终端设备可以接收组内的SCI,测量SCI中指示的PSSCH DMRS(Demodulation Reference Signal)的RSRP(Reference Signal Received Power),当存在多个DMRS符号时,进行线性平均,然后将测量得到的RSRP归一化为每个RE(Resource Element)上的RSRP,另外组内的终端设备可以对待测量资源进行测量得到RSSI(Received Signal Strength Indicator),并将测量得到的RSSI归一化为每个RE上的RSSI。最终将每个RE上的RSSI减去每个RE上的RSRP得到非本 组的终端设备对该待测量资源的干扰。对于没有数据传输的待测量资源,组内的终端设备直接对该待测量资源进行测量得到RSSI,并将测量得到的RSSI归一化为每个RE上的RSSI作为非本组的终端设备对该待测量资源的干扰。本申请实施例对获得非本组的终端设备对待测量资源产生的干扰的实现方式不做限制。
在一种可选的实施方式中,步骤S702在S701之前执行,第二终端在收到第一终端发送的第一指示消息之前已经完成了资源池的所有资源的测量,该资源池可以是从基站处获取,也可以是预配置的。这样第二终端在收到第一指示消息后可以直接根据指示信息进行第一信息的上报。
S703,第二终端将第一信息上报给第一终端。具体的,当第一终端配置的上报时机类型为周期性上报时,那么第二终端根据周期在固定的时刻进行第一信息的上报,如图7C所示,其中测量周期和上报周期可以不一样。当第一终端配置的上报时机类型为非周期性上报时,第一终端可以动态的指示第二终端在某个时刻进行第一信息的上报,或者当第二终端在接收到指示消息时,在缺省的时长(n时长)后的时刻进行第一信息的上报,如图7D所示。可选的,第一终端可以使用非周期性上报的方式选择性的触发部分第二终端进行第一信息的上报。例如,当第一终端需要获取其中某个第二终端的第一信息时,可以使用非周期性上报的方式指示该第二终端单独进行第一信息的上报。
第二终端确认上报时刻后,根据第一终端配置的具体的发送机制将第一信息发送给第一终端。当第一终端配置的发送机制为基于预留的资源进行第一信息的上报时,则第二终端使用预留的资源上报第一信息。当第一终端配置的发送机制为基于自由选择资源的第一信息的上报,则第二终端先进行资源的感知,再进行第一信息的上报。
结合前述的任一实施方式,在一种可选的实施方式中,第二终端上报的第一信息是M个比特位,其中M是第一终端指示的待测量资源集合中的待测量资源个数,每个比特位代表一个资源的测量是否满足测量门限。当该资源的测量低于测量门限时对应比特位置1;当该资源的测量不低于测量门限时对应比特位置0。这样,当第一终端收到第二终端发送的第一信息后,第一终端根据给该第二终端发送的待测量资源集合的指示,可以通过一一对应的方式得到每一个资源的测量结果。
结合前述的任一实施方式,在一种可选的实施方式中,第二终端上报的第一信息是M个字节,其中M是第一终端指示的资源个数,每个字节代表一个资源的测量是否满足测量门限。当该资源的测量低于测量门限时对应字节填写非0;当该资源的测量不低于测量门限时对应字节填写0。这样,当第一终端收到第二终端发送的第一信息后,第一终端根据给该第二终端发送的待测量资源集合的指示,可以通过一一对应的方式得到每一个资源块的测量结果。
结合前述的任一实施方式,在一种可选的实施方式中,第二终端上报的第一信息包括了一组资源的时频位置和测量结果。这样,当第一终端收到第二终端上 报的第一信息后,第一终端可以直接得到具体某个时频位置的资源的测量结果。
当第一终端接收到第二终端上报的第一信息后,将第一信息保存起来,如图7E示例性的给出了以表格的方式进行第二终端的第一信息的保存。表格中空白的位置代表第一终端没有指示该第二终端对此位置的资源块进行测量,例如第一终端没有指示第二终端2对资源1进行测量。第一终端也可以采用其他的方式进行第二终端上报的第一信息的存储,本申请实施例不做限制。
结合前述的任一实施方式,在一种可选的实施方式中,第二终端通过包括RRC(Radio Resource Control,无线资源控制)消息、MCE(MAC Control Element,MAC控制单元)消息、SCI(Sidelink Control Indicator,Sidelink控制指示)消息等消息来承载第一信息。其中SCI消息是通过控制信道(Physical Sidelink Control Channel,物理Sidelink控制信道)承载的,因此在第一信息中要增加上报的第二终端的用户标识,这样第一终端才能识别第一信息上报的第二终端。RRC消息和MCE消息是通过数据信道(Physical Sidelink Shared Channel,物理Sidelink共享信道)承载的,因此第一终端在接收到第一信息时可以通过加扰信息识别上报的第二终端。
综合前述的任一实施例方式,在一种可选的实施方式中,第二终端向第一终端上报第一信息后,第二终端测量和第一终端之间的距离,当该距离的变化达到第二距离门限时,第二终端主动向第一终端上报第一信息。这样可以解决由于第二终端的位置变化较大导致第一信息上报不及时的问题。
需要说明的是,第二终端测量得到的测量值可以直接和测量门限进行比较生成第一信息进行上报,或者第二终端测量得到的测量值可以进行滤波处理后和测量门限进行比较生成第一信息进行上报,本申请实施例不做限制。另外无线通信系统中还包括第三终端,第三终端属于其他组,第一信息包括第三终端对待测量资源集合中待测量资源的干扰的信息。
S704,第一终端获取可用的候选资源。具体的,第一终端参考第二终端上报的第一信息并结合第二信息决策得到可用的候选资源,其中第一信息为第二终端测量得到的资源集合,第二信息为第一终端测量得到的资源集合。
在一种可选的实施方式中,第一信息包括第二终端对待测量资源集合中的待测量资源进行测量获得的第一测量结果,第一终端对待测量资源集合中的待测量资源进行测量获得第二测量结果,第一终端将对第一测量结果和第二测量结果取交集确定的资源集合作为可用的候选资源。
在一种可选的实施方式中,第二终端测量得到的资源集合分别为S 1、S 2、……、S N,其中N为组成员的个数。第一终端测量得到的资源集合为S 0,资源集合S 0的元素个数为|S 0|。第一终端确定的可用的候选资源的个数为K,可用的候选资源包括第二资源集合和第三资源集合。
首先为了保证第一终端可使用的资源充足,第一终端根据第一信息和第二信息确定第二资源集合。具体的,第一终端从第四资源集合S′中选择K1个资源, 选择出来的K1个资源的集合为
Figure PCTCN2021106166-appb-000001
即第二资源集合。其中第四资源集合S′中的资源在第二终端中满足测量门限的比例大于或者等于第一比例,所述第一比例可以为60%或者80%等,若第一比例为100%,则表示取交集,若第一比例为1/N,则表示取并集;或者第四资源集合S′中的资源在第一终端与第二终端中满足测量门限的比例大于或者等于第一比例,所述第一比例可以为60%或者80%等,若第一比例为100%,则表示取交集,若第一比例为1/(1+N),则表示取并集。S′和S 0的交集为S′∩S 0,S′∩S 0中的元素个数为|S′∩S 0|。当|S′∩S 0|大于或者等于K1时,组头从S′∩S 0中选择所述K1个资源加入可用的候选资源,其中,所述K1个资源为第一终端测量得到的资源集合S 0中干扰最小的K1个资源,或者,所述K1个资源是从S′∩S 0中随机选择的K1个资源;当|S′∩S 0|小于K1时,第一终端选择S′∩S 0中所有的资源加入可用的候选资源,并且从S 0中选择K1-|S′∩S 0|个资源加入可用的候选资源,其中,所述K1-|S′∩S 0|个资源为S 0中干扰最小的K1-|S′∩S 0|个资源,或者,所述K1-|S′∩S 0|个资源是从S 0中随机选择的K1-|S′∩S 0|个资源。
接着第一终端根据第一信息和第二信息确定第三资源集合。具体的,第一终端从未被选中的资源中选择K-K1个资源加入可用的候选资源,其中所述K-K1个资源组成的集合为第三资源集合。具体的,S″为
Figure PCTCN2021106166-appb-000002
在所述S′中的相对补集,即S′中的元素属于S′但不属于
Figure PCTCN2021106166-appb-000003
相对补集S″中的元素个数为|S″|。当K-K1小于或者等于|S″|时,则在S″中随机选择K-K1个资源加入可用的候选资源;当K-K1大于|S″|时,第一终端选择S″中的所有资源加入可用的候选资源,然后从S 1、S 2、……、S N中未被选中的资源中随机选择K-K1-|S″|个资源加入可用的候选资源,或者优先从业务量大的第二终端测量得到的资源集合中选择K-K1-|S″|个资源加入可用的候选资源,若不够则从S 0中继续选择干扰最小的资源加入可用的候选资源直至满足第一终端对资源的需求,在选择资源时对于已被选择的资源不再重复选择。
需要说明的是,其中K1的取值可以和K相等,也就是说第一终端直接从第四资源集合中选择K1个资源后就达成对可用的候选资源的需求。
S705,第一终端根据本组可用的候选资源以及第四终端发送的可用资源情况,确定第一资源集合,第一资源集合中的资源为侧行链路通信的资源,其中第四终端为其他组的组头。具体的,第四终端在确定可用资源后将可用资源情况发送给第一终端,第一终端根据在步骤S704中确定的可用的候选资源以及其他组的可用资源情况,最终决策出第一资源集合。例如,在步骤S704中获得的可用的候选资源为资源1、资源2、资源3、资源4以及资源5,而接收到的第四终端发送的可用资源为资源3和资源4,那么第一终端决策第一资源集合为资源1、资源2以及资源5。当第一终端在决策出第一资源集合时,将第一资源集合通知给第四终端。
结合前述的任一实施方式,在一种可选的实施方式中,如果第一终端在基站 网络覆盖范围内,那么第一终端可以将可用的候选资源上报给基站,基站进行统一决策得到第一终端所在组的可用资源,然后将可用资源配置给第一终端。
在一种可选的实施方式中,不执行步骤S705,即直接将步骤S704中得到的可用的候选资源作为第一资源集合,即第一终端直接根据接收到的第一信息确定第一资源集合,也不用将第一资源集合通知给其他组的组头,直接执行步骤S706。
S706,第一终端发送第二指示消息发送给第二终端,第二指示消息用于指示第一资源集合的信息。当步骤S705在该实施例中存在时,第一终端将步骤S705中确定的第一资源集合发送给第二终端。当步骤S705在该实施例中不存在时,第一终端直接将步骤S704中得到的可用的候选资源作为第一资源集合发送给第二终端。
在一种可选的实施方式中,第一终端通过感知获取合适的资源后将第二指示消息发送给第二终端,由于通过感知获取合适的资源存在资源冲突的可能,第一终端可以采用多次重传的方式提高消息发送的成功率。具体的第一终端可以通过包括RRC(Radio Resource Control,无线资源控制)消息、MCE(MAC Control Element,MAC控制单元)消息、SCI(Sidelink Control Indicator,Sidelink控制指示)消息等消息将第二指示消息发送给第二终端。当第二指示消息的信息较小时,比较适合使用SCI消息进行承载,这样可以节省资源的开销;当第二指示消息的信息较大时,比较适合使用RRC消息或者MCE消息进行承载,这样可以利于第二指示消息大小的扩展。
S707,第一终端和第二终端中至少一个使用第一资源集合中的资源进行侧行链路的通信。图7A中未示出本步骤。具体的,组内终端设备,包括第一终端和第二终端,需要给组内其他设备发送数据时,对第一资源集合中的资源进行感知获得合适的侧行链路资源,然后通过该侧行链路资源发送数据。
结合图4A,图8A示出了本申请实施例提供的一种信息上报的方法,该方法应用于无线通信系统,该无线通信系统包括第一终端和第二终端,其中第一终端为组头,第二终端为组成员,第二终端为一个或多个,该方法是第二类状态信息的上报,包括:
S801,第一终端发送第一指示消息给第二终端,第一指示消息用于指示第二终端上报第一信息。具体的第一指示消息中的指示信息除了上报内容类型的指示和测量门限的指示与图7A中步骤S701存在区别外,其他的指示信息如图7A中步骤S701的描述,在此不再赘述。
在该实施例中上报内容类型为第二类状态信息,第二类状态信息为信道资源的信道质量。具体的信道质量包括RSRP(Reference Signal Receiving Power,参考信号接收功率)、SINR(Signal to Interference plus Noise Ratio,信号与干扰加噪声比)或者RSRQ(Reference Signal Receiving Quality,参考信号接收质量)等。如 图8B所示,假设第一终端给第二终端配置的测量资源集为S,包括5个测量资源,当干扰测量指示为RSRP时,第二终端通过测量后得到的该5个测量资源上的干扰值分别为-80dBm、-85dBm、-75dBm、-70dBm,-80dBm。
在该实施例中由于第二终端直接上报干扰测量值,因此第一终端不用发送测量门限的指示给第二终端。
S802,第一终端和第二终端对资源进行测量。具体的测量方式和步骤S702中的描述一致,在此不再赘述。
与图7A中的步骤S702中描述的类似,在一种可选的实施方式中,步骤S802在S801之前执行,第二终端在收到第一终端发送的第一指示消息之前已经完成了资源池的所有资源的测量,该资源池可以是从基站处获取,也可以是预配置的。这样,第二终端在收到第一指示消息后直接根据指示信息进行第一信息的上报。
S803,第二终端将第一信息上报给第一终端。具体的,除了上报的内容和图7A中步骤S703存在区别外,其余内容和图7A中步骤S703的描述一致,在此不再赘述。在该实施例中,第二终端将对指定资源测量后将具体的干扰值上报给第一终端。
在一种可选的实施方式中,第二终端对指定资源进行测量得到干扰值但不进行任何处理,直接将具体的干扰值上报给第一终端。
在一种可选的实施方式中,第二终端对指定资源进行测量得到干扰值并进行滤波平滑等处理后,将经过处理后的测量结果上报给第一终端。
S804,第一终端获取可用的候选资源。具体的第一终端参考第二终端上报的第一信息并结合第二信息决策得到可用的候选资源,其第一信息为第二终端测量得到的干扰集合,第二信息为第一终端测量得到的干扰集合。
第二终端测量得到的干扰集合分别为S 1、S 2、……、S N,其中N为组成员的个数,第一终端测量得到的干扰集合为S 0。第一终端确定的可用的候选资源的个数为K。可用的候选资源包括第二资源集合和第三资源集合。
首先为了保证第一终端可使用的资源充足,第一终端根据第二信息确定第二资源集合,其中第二信息为第一终端测量得到的资源集合即S 0,第二资源集合是第一终端从第四资源集合中确定的,在该实施例中第四资源集合为第一终端测量得到的资源集合S 0。具体的,第一终端从S 0中选择K1个干扰最小的资源加入可用的候选资源,其中K1小于或者等于K。接着第一终端根据第一信息和第二信息确定第三资源集合,具体的,第一终端从未被选择的资源中选择K-K1个资源加入可用的候选资源,所述K-K1个资源组成的集合为第三资源集合,第三资源集合的资源数量K-K1为第三数量。
在一种可选的实施方式中,第一终端根据第二终端的业务量对第二终端测量得到的干扰集合进行降序排列,降序排列后的第二终端测量得到的干扰集合为S ′1、 S′ 2、……、S′ N,其中S′ 1为业务量最大的第二终端测量得到的干扰集合,S′ N为业务量最小的第二终端测量得到的干扰集合。第一终端按照降序排列的顺序从干扰集合中依次循环选择干扰最小的资源加入可用的候选资源,直至选择K-K1个可用的候选资源为止,在选择资源时对于已被选中的资源不再重复选择。
在另一种可选的实施方式中,第一终端计算每个资源的干扰平均值,当测量的干扰值为RSRP时,干扰平均值的计算公式为
Figure PCTCN2021106166-appb-000004
l可以取值为0或1,其中
Figure PCTCN2021106166-appb-000005
表示第一终端对第m个资源进行测量得到的干扰值,
Figure PCTCN2021106166-appb-000006
表示第n个第二终端对第m个资源进行测量得到的干扰值,单位为毫瓦(mW)。第一终端选择干扰平均值最小的K-K1个资源加入可用的候选资源,在选择资源时对于已被选中的资源不再重复选择。
在另一种可选的实施方式中,第一终端将每个资源上的干扰值转换为频谱效率,当测量的干扰值为RSRP时,具体的转换公式为
Figure PCTCN2021106166-appb-000007
其中E n,m表示第n个第二终端在第m个资源的频谱效率,rsrp 0为固定值(比如可以取值为-80dBm),
Figure PCTCN2021106166-appb-000008
表示第n个第二终端对第m个资源进行测量得到的干扰值。然后结合第二终端的业务量计算每个资源的传输时间,具体的计算公式为
Figure PCTCN2021106166-appb-000009
其中G n为第n个第二终端的业务量。第一终端选择传输时间最小的K-K1个资源加入可用的候选资源,在选择资源时对于已被选择的资源不再重复选择。
需要说明的是,其中K1的取值可以和K相等,也就是说第一终端直接从第四资源集合中选择K1个资源后就达成对可用的候选资源的需求。
由于该实施例中第二终端上报的第一信息是资源的具体干扰值,在一种可选的实施方式中,第一终端可以根据第二终端上报的终端能力设置不同的测量门限,例如对时延和吞吐量要求不高的终端,第一终端可以将测量门限设置的高一些;对时延和吞吐量要求高的终端,第一终端可以将测量门限设置的低一些。这样对于不同的第二终端获得的可用的候选资源是不同的。
S805,第一终端根据本组可用的候选资源以及其他组的组头发送的可用资源情况,确定第一资源集合,第一资源集合中的资源为侧行链路通信的资源。该步骤和图7A中步骤S705的描述一致,在此不再赘述。
需要说明的是,如果在步骤S804中对于不同的第二终端获得的可用的候选资源是不同的,那么第一终端结合其他组的组头发送的可用资源情况给不同的第二终端确定的第一资源集合也是不同的。当第一终端获得每一个第二终端的第一资源集合后,第一终端将所有第二终端的第一资源集合的交集通知给其他组的组头。
S806,第一终端发送第二指示消息发送给第二终端,第二指示消息为指示第一资源集合的信息。该步骤和图7A中步骤S706的描述一致,在此不再赘述。
需要说明的是,当对于不同的第二终端决策得到的第一资源集合不一样时, 第一终端发送给不同的第二终端的第一资源集合也是不同的。
S807,第一终端和第二终端中至少一个使用第一资源集合中的资源进行侧行链路的通信。图8A中未示出本步骤。该步骤和图7A中步骤S707的描述一致,在此不再赘述。
结合图4A,图9A示出了本申请实施例提供的一种信息发送的方法,该方法应用于无线通信系统,该无线通信系统包括第一终端和第二终端,其中第一终端为组头,第二终端为组成员,第二终端为一个或多个,该方法是第三类型状态信息的上报,包括:
S901,第一终端发送第一指示消息给第二终端,第一指示消息用于指示第一终端上报第一信息。具体的第一指示消息中的指示信息除了上报内容类型的指示和测量门限的指示与图7A中步骤S701存在区别外,其他的指示信息如图7A中步骤S701的描述,在此不再赘述。
在该实施例中上报内容类型为第三类状态信息,第三类状态信息用于指示信道资源的误码率超是否满足第二阈值门限。具体第二终端在第一终端指示的测量资源上统计数据传输的误码率。第一终端配置的测量门限即第二阈值门限包括1%、5%、10%等。在一种可选的实施方式中,第二终端可以使用默认的测量门限,例如5%,无需从第一终端获取。
S902,第一终端和第二终端对资源进行测量。由于对资源的误码率的测量需要在该资源上进行业务数据的传输,因此只有在进行了一段时间的数据传输后才能获取到误码率。
在一种可选的实施方式中,该实施例的上报内容类型的指示可以在其他的上报内容类型的指示运行了一段时间后,第一终端为了获得更好的性能,第一终端进行该实施例的上报内容类型的指示。
在一种可选的实施方式中,第一终端在初始阶段就将该实施例的上报内容类型的指示发送给第二终端,第二终端在进行一段时间的数据传输后将第一信息上报给第一终端。
与图7A中的步骤S702中描述的类似,在一种可选的实施方式中,步骤S902在S901之前,第二终端在收到第一终端发送的第一指示消息之前已经进行了一段时间的数据传输,第二终端已经获得了使用过的资源上的误码率。这样,第二终端在收到第一指示消息后直接根据指示信息进行第一信息的上报。
S903,第二终端将第一信息上报给第一终端。具体的,除了上报的内容和图7A中步骤S703存在区别外,其余内容和图7A中步骤S703的描述一致,在此不再赘述。在该实施例中,第二终端将指定资源的测量结果上报给第一终端。如图9B所示,假设第一终端配置的测量资源集为S,包括5个测量资源,其中资源2 和资源3的误码率低于误码率门限,则在对应的资源上置1;其余资源的误码率不低于误码率门限,则在对应的资源上置0。
S904,第一终端获取可用的候选资源。具体的第一终端参考第二终端上报的第一信息并结合自己的测量信息决策得到可用的候选资源。该步骤和图7A中步骤S704的描述一致,在此不再赘述。
S905,第一终端根据本组可用的候选资源以及其他组的组头发送的可用资源情况,确定第一资源集合,其中第一资源集合中的资源为侧行链路通信的资源。该步骤和图7A中步骤S705的描述一致,在此不再赘述。
S906,第一终端发送第二指示消息发送给第二终端,第二指示消息为指示第一资源集合的信息。该步骤和图7A中步骤S706的描述一致,在此不再赘述。
S907,第一终端和第二终端中至少一个使用第一资源集合中的资源进行侧行链路的通信。图9A中未示出本步骤。该步骤和图7A中步骤S707的描述一致,在此不再赘述。
从上述给出的本申请的实施例中可以看出,在利用Group机制的Sidelink技术中,组头获取整个组的干扰等信息后可以统一协调提供可靠的信息输入,解决组中边缘终端设备干扰大和资源利用率不足的问题,提升系统的通信性能。从上述实施例中可以看出,三种实施例提供的信息上报的方法各有优势,在图7的第一类状态信息上报的方法中,组成员设备上报的第一信息比较简单,这样组成员设备在上报第一信息时占用的资源比较少。在图8的第二类状态信息上报的方法中,组成员设备上报的是资源的具体测量值,这样组头可以根据具体的测量值进行不同组成员设备的差异化处理。在图9的第三类状态信息上报的方法中,组头可以根据实际的数据传输的误码情况确定侧行链路通信的资源。
根据上面的描述,组头可以根据不同的场景进行第一指示消息的切换。例如首先组头使用第一类状态信息上报的方法,运行一段时间后,组头可以使用第三类状态信息上报的方法,这样组头可以获取到资源的误码情况,根据误码情况获得侧行链路通信的资源,这样决策得到的侧行链路通信的资源更加准确,另外当误码率达到了阈值时,则将第一信息上报的指示切换到第二类状态信息上报的方法,这样可以获得组成员设备上报的更加精确的测量结果,还可以对组成员设备进行差异化处理,提高整个组的系统效率。
下面给出本申请实施例提供的一种信息上报的方法,该方法应用于无线通信系统,该无线通信系统包括第一终端和第二终端,其中第一终端为第一组的组头,如图10所示,该方法包括:
S1001,第二终端向第一终端发送入组申请,响应于接收到的组头发送的申请通过消息,加入第一组成为第一组成员。具体的,第二终端检测周围存在的第一组后,第二终端可以接收第一操作,即用户的选择,加入第一组,如图4B和4C所示。也可以由第二终端自主选择加入第一组,例如第二终端选择加入与该组的组头之间的距离最近的组。
S1002,第二终端上报第一信息给第一终端,第一信息为辅助第一终端选择第一资源集合的信息,其中第一资源集合中的资源为侧行链路通信的资源。
在一种可选的实施方式中,第二终端加入第一组成为第一组成员后,按照默认支持的第一信息的上报的类型向第一终端上报第一信息。
在一种可选的实施方式中,第一终端检测到新增第一组成员后,发送第一指示消息给第一组成员,第一组成员按照该第一指示消息向第一终端上报第一信息。具体的第一指示消息和图7中的步骤S701描述的一致,在此不再赘述。
S1003,第二终端接收第一终端发送第二指示消息,第二指示消息为指示第一资源集合的信息。具体的第一资源集合的确定和发送如图7中的步骤S704-S706描述的一致,在此不再赘述。
在一种可选的实施方式中,所有的终端默认支持某种类型的第一信息的上报,例如默认支持第一类状态信息的上报,终端加入某个组成为组成员设备后就按照默认周期或者根据与组头之间的位置变化自主地向组头上报进行第一信息。也就是说组成员设备不需要等接收到组头发送的第一指示消息才向组头上报进行第一信息。
参考图11,其示出了本申请实施例提供的组头触发组成员进行第一信息上报的方法,该方法包括:
S1101,组头决策进行第一信息上报流程。
在一种可选的实施方式中,组头可以进行手动设置进入第一信息上报流程。
在一种可选的实施方式中,组头通过检测当前资源冲突的概率,当资源冲突的概率达到阈值时,切换到第一信息上报流程。
在一种可选的实施方式中,当组头在基站网络范围内,那么基站可以配置组头进入第一信息上报流程。
S1102,组头发送第一指示消息给组成员设备,第一指示消息用于指示组成员设备上报第一信息。该步骤和图7-9中的实施例的描述一致,在此不再赘述。
组成员设备接收到第一指示消息后的处理和图7-9中的实施例的描述一致,在此不再赘述。
下面给出本申请实施例提供的一种信息发送的方法,应用于无线通信系统,无线通信系统包括第一终端、第二终端和第三终端,其中第一终端和第二终端属于同一通信组,第一终端为组头,第二终端为组成员,如图12所示,该方法包括:
S1201,第一终端发送第一指示消息给第二终端,第一指示消息用于指示第二终端上报第一信息,第一指示信息包括待测量资源集合的指示。
S1202,第二终端根据第一指示消息向第一终端上报第一信息,该第一信息包括第三终端对待测量资源集合中测量资源的干扰信息。
S1203,第一终端发送第二指示消息给第二终端,其中,第二指示消息为指示第一资源集合的信息,其中第一资源集合中的资源为侧行链路通信的资源,第一资源集合中不包括第三终端对待测量资源集合的干扰满足预设条件的资源。
在一种可选的实施方式中,第一资源集合中不包括第三终端对待测量资源集合中测量资源的干扰信息达到干扰门限的资源。
在一种可选的实施方式中,第一资源集合中不包括第三终端、第二终端和第一终端对待测量资源集合中测量资源的干扰信息达到干扰门限的资源。
S1204,第一终端和第二终端中的至少一个使用所述第一资源集合中的资源进行侧行链路的通信。
