Description

抢占信息的传输方法、设备及系统
本申请要求于2018年03月07日提交中国专利局、申请号为201810187541.8、申请名称为“抢占信息的传输方法、设备及系统”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
本申请涉及无线通信技术领域，尤其涉及抢占信息的传输方法、设备及系统。
背景技术
随着移动通信技术的发展，车联网使用无线通信、以及传感探测等技术收集车辆、道路、环境等信息，通过车车通信(vehicle to vehicle，V2V)实现智能交通管理控制和车辆智能化控制的一体化网络，近年来市场呈爆发式增长，且潜力巨大。
其中，在目前第三代合作伙伴计划(3rd generation partnership project，3GPP)版本(release 14，Rel.14)V2X技术中，定义了两种资源的使用模式：一种是模式(mode)3，基站为每个终端在侧行链路上分配资源，以用于该终端进行控制信息及数据的传输；另一种是mode 4，终端根据现有的侦听(sensing)流程确定备选资源集合，进而在备选资源集合中再随机选择资源，以用于该终端进行控制信息及数据的传输。
然而，由于目前的第五代(5rd generation，5G)V2X需要支持突发(burst)业务，而该突发业务的特点是：事件触发，业务未必是严格周期性的，对于可靠性和时延等要求较高，因此现有的mode 4对应的资源使用模式存在如下问题：
一方面，其他终端在选择资源时并不能提前知道突发业务的存在，因此可能和有突发业务的终端选择到相同的资源，从而降低了突发业务数据传输的可靠性。
另一方面，若当前资源池发生拥塞，或者若当前资源选择窗内发生拥塞，则由于现有的侦听流程是通过不断提高参考信号接收功率(reference signal received power，RSRP)门限的方式来选择足够数量的备选资源构成备选资源集合，因此将导致更多高干扰的资源进入备选资源集合，进而若再从该备选资源集合中随机选择资源发送突发业务数据，则将会进一步降低突发业务数据传输的可靠性。
因此，如何提高突发业务数据传输的可靠性，是目前亟待解决的问题。

具体实施方式
首先，对本申请涉及的相关技术及相关术语进行简单介绍，以方便读者理解：
资源：本申请实施例中的资源也可以称之为时频资源，即包括时域资源和频域资源。目前，时域资源的最小单元为符号；频域资源的最小单元为子载波。
目前的长期演进(long term evolution，LTE)系统中，定义一个无线帧包括10个子帧(subframe)，每个子帧的长度为1毫秒(ms)，每个子帧包括两个时隙(slot)，每个slot为0.5ms。每个slot包括的符号的个数与子帧中循环前缀(cyclic prefix，CP)的长度相关。若CP为普通(normal)CP，则每个slot包括7个符号，每个子帧由14个符号组成，例如，如图1所示，每个子帧可以由序号分别为#0，#1，#2，#3，#4， #5，#6，#7，#8，#9，#10，#11，#12，#13的符号组成。若CP为长(extended)CP，则每个slot包括6个OFDM符号，每个子帧由12个符号组成，例如，如图2所示，每个子帧可以由序号分别为#0，#1，#2，#3，#4，#5，#6，#7，#8，#9，#10，#11的符号组成。此外，定义一个物理资源块(physical resource block，PRB)的大小为时域上的一个时隙，频域上的180kHz。当子载波间隔为15kHz时，如图1或图2所示，一个PRB在频域上包括12个子载波，此时一个PRB共包含84个或72个资源单元(resource element，RE)，RE可以由索引对(k，l)唯一标识，其中，k为子载波索引，l为符号索引。同时，在频域上对PRB进行编号，即为PRB索引或PRB序号。定义一个PRB对(PRB pair)为在一个子帧上的两个时隙的PRB索引或PRB序号相同的一对PRB。
目前的5G系统中，定义一个无线帧包括10个子帧，每个子帧的长度为1毫秒(ms)，每个子帧包括一个或多个时隙(slot)。此外，定义一个物理资源块(physical resource block，PRB)在频域上包括12个子载波,在频域上对PRB进行编号，即为PRB索引或PRB序号。
需要说明的是，本申请实施例中，由于PRB序号是在频域上对PRB进行的编号，在频域上包括12个子载波，因此本申请实施例附图中的PRB序号在坐标系中不代表一个坐标值，而是仅是示意性的表示一个PRB的频域范围。比如，图3中，PRB序号为q的一个PRB表示虚线1和虚线2之间的一段频域范围，在此进行统一说明，以下不再赘述。
抢占信息：本申请实施例中的抢占信息用于指示第一资源被第一通信设备占用。
其中，该抢占信息例如可以包括第一资源的时域位置信息、第一资源的频域位置信息、第一资源上数据的优先级、第一资源上数据的调制编码方式(Modulation and Coding Scheme，MCS)、第一资源的周期、或者预计占用的次数中的至少一个。
本申请实施例中，第一资源的时域位置信息例如可以包括第一资源与用于发送抢占信息的第二资源之间的时间间隔以及第一资源的时域大小；或者，可选的，第一资源的时域位置信息例如可以包括第一资源的时域起始位置以及第一资源的时域结束位置；或者，可选的，为了减少时延，若预先配置用于发送抢占信息的第二资源和第一通信设备要占用的第一资源占用连续的时域资源，则可以不用在第一资源的时域位置信息中指示第一资源与用于发送抢占信息的第二资源之间的时间间隔或者第一资源的时域起始位置，在此统一说明，以下不再赘述。
本申请实施例中，第一资源的频域位置信息例如可以包括第一资源的频域起始位置和第一资源的频域结束位置；或者，第一资源的频域位置信息例如可以包括第一资源的频域起始位置和第一资源的频域大小。其中，第一资源的频域起始位置由第一资源的频域起始PRB序号进行表示，第一资源的频域结束位置由第一资源的频域结束PRB序号进行表示，第一资源的频域大小通常由第一资源所对应的PRB序号的个数或者第一资源所对应的子载波的个数进行表征。
可选的，本申请实施例中，第一资源的时域也可以称之为第一资源对应的时域资源，第一资源的频域也可以称之为第一资源对应的频域资源，本申请实施例对此不作具体限定。
时分：本申请实施例中的时分是指在同一频域资源，不同时域资源上。
频分：本申请实施例中的频分是指在不同频域资源上，时域资源可以相同，也可以不同。
侧行链路控制信息(sidelink control information)：本申请实施例中的SCI是指从发送端发出的控制信息，用于指示数据传输所占用的资源、MCS、或者业务优先级等信息，接收端能够根据SCI的指示进行数据的接收。可选的，本申请实施例中的SCI也可以称之为调度分配(scheduling assignment，SA)，在此统一说明，以下不再赘述。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种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。并且，在本申请的描述中，除非另有说明，“多个”是指两个或多于两个。另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
此外，本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
如图4所示，为本申请实施例提供的一种抢占信息的传输系统40，该抢占信息的传输系统40包括第一通信设备401以及一个或多个与第一通信设备401通信的第二通信设备402。下面以第一通信设备401与任意第二通信设备402的通信为例进行说明。
第一通信设备401，用于确定要占用的第一资源以及用于发送抢占信息的第二资源，并在第二资源上向第二通信设备402发送抢占信息。其中，该抢占信息用于指示第一资源被第一通信设备占用，第二资源的时域位置在第一资源的时域位置之前；
第二通信设备402，用于在第二资源上接收来自第一通信设备401的抢占信息，并根据该抢占信息，对第一资源进行资源躲避。
其中，本申请实施例中，第一资源和第二资源的相关描述可参考具体实施方式前序部分对于资源的描述，抢占信息的相关描述可参考具体实施方式前序部分，在此不再赘述。
虽然未示出，该抢占信息的传输系统40还可以包括网络设备，该网络设备用于为第一通信设备401和第二通信设备402配置资源池配置所需的信息，如下述实施例中的资源配置参数等，本申请实施例对此不作具体限定。可选的，本申请实施例中的网络设备例如可以包括基站、中继站或接入点等，本申请实施例对此不作具体限定。其中，本申请实施例中的基站例如可以是全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)网络中的基站收发信台(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的NB(NodeB)，还可以是LTE中的eNodeB (evolutional NodeB)或者5G以及未来其他网络中的基站等，本申请实施例对此不作具体限定。
可选的，本申请实施例中所涉及到的通信设备(包括第一通信设备401、第二通信设备402以及下述的第三通信设备等)例如可以包括终端(terminal)或者终端内的芯片或电路等，本申请实施例对此不作具体限定。其中，本申请实施例中的终端例如可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备；还可以包括用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)或者无线本地环路(wireless local loop，WLL)台、机器类型通信(machine type communication,MTC)终端、用户设备(user equipment，UE)，移动台(mobile station，MS)，终端设备(terminal device)或者中继用户设备等。其中，中继用户设备例如可以是5G家庭网关(residential gateway，RG)。为方便描述，本申请中，上面提到的设备统称为终端。
基于本申请实施例提供的抢占信息的传输系统，由于第一通信设备可以在确定要占用的第一资源之后，向第二通信设备发送指示第一资源被第一通信设备占用的抢占信息，使得第二通信设备可以获知第一资源被第一通信设备占用，进而对第一资源进行躲避，因此可以在第一通信设备有突发业务时，减少第一通信设备和第二通信设备选择到相同资源的概率，从而提升突发业务数据传输的可靠性。
可选的，本申请实施例图4中的第一通信设备或第二通信设备可以由一个设备实现，也可以由多个设备共同实现，还可以是一个设备内的一个功能模块，本申请实施例对此不作具体限定。可以理解的是，上述功能既可以是硬件设备中的网络元件，也可以是在专用硬件上运行的软件功能，或者是平台(例如，云平台)上实例化的虚拟化功能。
例如，本申请实施例图4中的第一通信设备或第二通信设备可以通过图5中的通信设备来实现。图5所示为本申请实施例提供的通信设备的硬件结构示意图。该通信设备500包括至少一个处理器501，通信线路502，存储器503以及至少一个通信接口504。
处理器501可以是一个通用中央处理器(central processing unit，CPU)，微处理器，特定应用集成电路(application-specific integrated circuit，ASIC)，或一个或多个用于控制本申请方案程序执行的集成电路。
通信线路502可包括一通路，在上述组件之间传送信息。
通信接口504，使用任何收发器一类的装置，用于与其他设备或通信网络通信，如以太网，无线接入网(radio access network，RAN)，无线局域网(wireless local area networks，WLAN)等。

其中，存储器503用于存储执行本申请方案的计算机执行指令，并由处理器501来控制执行。处理器501用于执行存储器503中存储的计算机执行指令，从而实现本申请下述实施例提供的抢占信息的传输方法。
可选的，本申请实施例中的计算机执行指令也可以称之为应用程序代码，本申请实施例对此不作具体限定。
在具体实现中，作为一种实施例，处理器501可以包括一个或多个CPU，例如图5中的CPU0和CPU1。
在具体实现中，作为一种实施例，通信设备500可以包括多个处理器，例如图5中的处理器501和处理器508。这些处理器中的每一个可以是一个单核(single-CPU)处理器，也可以是一个多核(multi-CPU)处理器。这里的处理器可以指一个或多个设备、电路、和/或用于处理数据(例如计算机程序指令)的处理核。
在具体实现中，作为一种实施例，通信设备500还可以包括输出设备505和输入设备506。输出设备505和处理器501通信，可以以多种方式来显示信息。例如，输出设备505可以是液晶显示器(liquid crystal display，LCD)，发光二级管(light emitting diode，LED)显示设备，阴极射线管(cathode ray tube，CRT)显示设备，或投影仪(projector)等。输入设备506和处理器501通信，可以以多种方式接收用户的输入。例如，输入设备506可以是鼠标、键盘、触摸屏设备或传感设备等。
上述的通信设备500可以是一个通用设备或者是一个专用设备。在具体实现中，通信设备500可以是台式机、便携式电脑、网络服务器、掌上电脑(personal digital assistant，PDA)、移动手机、平板电脑、无线终端设备、嵌入式设备或有图5中类似结构的设备。本申请实施例不限定通信设备500的类型。
下面将结合图1至图5对本申请实施例提供的抢占信息的传输方法进行具体阐述。
结合图4所示的抢占信息的传输系统，以第一通信设备与任一第二通信设备的通信为例，如图6所示，为本申请实施例提供的一种抢占信息的传输方法，包括如下步骤：
S601、第一通信设备确定要占用的第一资源。
S602、第一通信设备确定用于发送抢占信息的第二资源，其中，第二资源的时域位置在第一资源的时域位置之前。
S603、第一通信设备在第二资源上向第二通信设备发送抢占信息。
S604、第二通信设备在第二资源上接收来自第一通信设备的抢占信息。
S605、第二通信设备根据抢占信息，对第一资源进行资源躲避。
下面将分别针对各个步骤展开进行描述。
其中，本申请实施例步骤S601中：
第一通信设备可以通过如下方式确定要占用的第一资源。
方式一：第一通信设备根据接收到的其它终端发送的SCI中指示的业务优先级以及其它终端发送的SCI中指示的资源，确定要占用的第一资源。
一种可能的实现方式中，第一通信设备可以将接收到的其它通信设备发送的SCI中指示的业务优先级和第一终端自身的业务优先级进行比较，将业务优先级高于或者等于自身的业务优先级的通信设备发送的SCI中指示的资源从备选资源集合中排除之后，从备选资源集合中选择要占用的第一资源。
示例性的，假设第一通信设备接收到第四通信设备和第五通信设备发送的SCI，第四通信设备发送的SCI中指示的业务优先级为A，第五通信设备发送的SCI中指示的业务优先级为B，第一通信设备自身的业务优先级为C，若优先级级别为A＞C＞B，也就是说第一通信设备的业务优先级低于第四通信设备的业务优先级，第一通信设备的业务优先级高于第五通信设备的业务优先级，则第一通信设备将第四通信设备发送的SCI中指示的资源从备选资源集合中排除之后，从备选资源集合中选择要占用的第一资源。比如，备选资源集合中包括第五通信设备发送的SCI中指示的资源，则第一通信设备可以确定该第一资源为第五通信设备发送的SCI中指示的资源。
另一种可能的实现方式中，第一通信设备可以将接收到的其它终端发送的SCI中指示的业务优先级和预设的业务优先级进行比较，将业务优先级高于或者等于预设的业务优先级的通信设备发送的SCI中指示的资源从备选资源集合中排除之后，从备选资源集合中选择要占用的第一资源。
示例性的，假设第一通信设备接收到第四通信设备和第五通信设备发送的SCI，第四通信设备发送的SCI中指示的业务优先级为A，第五通信设备发送的SCI中指示的业务优先级为B，预设的业务优先级为C，若优先级级别为A＞C＞B，也就是说预设的业务优先级低于第四通信设备的业务优先级，预设的业务优先级高于第五通信设备的业务优先级，则第一通信设备将第四通信设备发送的SCI中指示的资源从备选资源集合中排除之后，从备选资源结合中选择要占用的第一资源。比如，备选资源集合中包括第五通信设备发送的SCI中指示的资源，则第一通信设备可以确定该第一资源为第五通信设备发送的SCI中指示的资源。
可选的，若多个通信设备发送的SCI中指示的业务优先级低于预设的业务优先级，则第一通信设备可以从这多个通信设备发送的SCI中指示的资源中随机选择一个资源作为第一资源，本申请实施例对此不作具体限定。
方式二：第一资源可以为第三通信设备占用的资源或者第三通信设备占用的资源中的部分资源。也就是说，第一通信设备尽量占用一个其他通信设备的资源，以尽量减少影响的通信设备的数据量。
示例性的，如图7所示，当第一通信设备有三个备选资源(两个实线框资源和一个虚线框资源)时，则第一通信设备优先选择实线框资源，尽量避免选择虚线框资源。原因在于：若选择了实线框资源，则仅有一个其它通信设备(如第四通信设备或第五通信设备)被影响，而当选择了虚线框资源时，则有更多其它通信设备(如第四通信设备和第五通信设备)被影响。
需要说明的是，上述仅是示例性的提供了两种第一通信设备确定要占用的第一资 源的方式，当然，第一通信设备还可以通过其他方式确定要占用的第一资源，比如从备选资源集合中随机选取第一资源等，或者在第一通信设备确定要占用的第一资源时，可以同时考虑方式一和方式二，本申请实施例对此不作具体限定。
其中，本申请实施例步骤S602中：
第一通信设备可以通过如下方式确定用于发送抢占信息的第二资源。
方式一：第二资源为用于发送抢占信息的专用资源集合中的资源。
也就是说，可以预先配置一个资源集合，该资源集合中的资源仅用于发送抢占信息，不能用于发送除抢占信息之外的其他信息。该场景下，第一通信设备可以首先根据第一参数确定可用于发送抢占信息的专用资源集合，进而从专用资源集合中确定用于发送抢占信息的第二资源。比如，从专用资源集合中随机选择资源作为第二资源，或者进一步根据第二参数确定第二资源，本申请实施例对此不作具体限定。其中，该第一参数或第二参数可以是资源配置参数中的参数。本申请实施例中的资源配置参数可以为网络设备配置的参数或者预先配置在第一通信设备上的参数等，本申请实施例对此不作具体限定。
可选的，本申请实施例中的第一参数或第二参数例如可以包括用于发送抢占信息的专用资源集合的时域位置信息或者频域位置信息中的至少一个。
示例性的，如图8所示，当第一资源和第二资源为频分时，本申请实施例中的第一参数例如可以包括用于发送抢占信息的专用资源集合(即图8中的资源集合2)的频域位置信息；可选的，该第一参数还可以包括用于发送抢占信息的专用资源集合的时域位置信息，本申请实施例对此不作具体限定。其中，图8中的资源集合1为用于发送除抢占信息之外的其他信息的资源的集合，包括上述的第一资源。
可选的，本申请实施例中的第一资源集合和第二资源集合可以是在频域上连续的资源的集合，也可以是在频域上不连续的资源的集合，图8仅是示意性的以第一资源集合和第二资源集合为在频域上不连续的资源的集合为例进行说明，本申请实施例对此不作具体限定。此外，当第一资源集合和第二资源集合为在频域上不连续的资源的集合的情况下，第一资源集合和第二资源集合通常属于不同的资源池；当第一资源集合和第二资源集合为在频域上连续的资源的集合的情况下，第一资源集合和第二资源集合可以属于同一个资源池，也可以属于不同的资源池，本申请实施例对此不作具体限定。
或者，示例性的，如图9所示，当第一资源和第二资源为时分时，本申请实施例中的第一参数例如可以包括用于发送抢占信息的专用资源集合，比如每个调度时间单元(以下简称时间单元)的最后两个符号；可选的，该第一参数还可以包括用于发送抢占信息的专用资源集合的频域位置信息，本申请实施例对此不作具体限定。
需要说明的是，本申请实施例中的时间单元例如可以是LTE系统中的子帧或者5G系统中的时隙，本申请实施例对此不作具体限定。
方式二：第二资源为用第一通信设备的预留资源中的资源。
也就是说，本申请实施例中，若第一通信设备恰好有预留资源，则可以使用预留资源发送抢占信息，本申请实施例对此不作具体限定。其中，该预留资源是指预留的在时间上具有周期性的资源,通常用于发送周期性的数据，本申请实施例以预留资源在 时域上以1个时间单元为单位进行说明，在此统一说明，以下不再赘述。
可选的，本申请实施例中的预留资源还可以用于发送SCI以及SCI对应的数据。也就是说，本申请实施例中的抢占信息可以随SCI或者SCI对应的数据一起发送。
示例性的，当资源池中的资源可以频分时，抢占信息随SCI或者SCI对应的数据一起发送的示意图可以如图10至图13所示。其中，在图10和图11中，用于发送数据的资源和用于发送SCI的资源属于同一个资源池；在图12和图13中，用于发送数据的资源和用于发送SCI的资源属于不同的资源池，比如，SCI资源池用于发送SCI；数据资源池用于发送数据。其中，在图10中，用于发送抢占信息的资源和用于发送SCI的资源是时分的；在图11中，用于发送抢占信息的资源和用于发送SCI的资源是频分的；在图12中，抢占信息随SCI一起发送，用于发送抢占信息的资源和用于发送SCI的资源是频分的；在图13中，抢占信息随SCI对应的数据一起发送，用于发送抢占信息的资源和用于发送SCI对应的数据的资源是频分的。
需要说明的是，上述图10至图13仅是示例性的说明抢占信息可以随SCI或者SCI对应的数据一起发送，当然，抢占信息随SCI或者SCI对应的数据一起发送的示意图也可以为其它，比如，在图12中，用于发送抢占信息的资源和用于发送SCI的资源也可以是时分的；在图13中，用于发送抢占信息的资源和用于发送SCI对应的数据的资源也可以是时分的，本申请实施例对此不作具体限定。
或者，示例性的，当资源池中的资源可以时分时，抢占信息随SCI或者SCI对应的数据一起发送的示意图可以如图14至图17所示。其中，在图14和图15中，用于发送数据的资源和用于发送SCI的资源属于同一个资源池；在图16和图17中，用于发送数据的资源和用于发送SCI的资源属于不同的资源池，比如，SCI资源池用于发送SCI；数据资源池用于发送数据。其中，在图14中，用于发送抢占信息的资源和用于发送SCI的资源是时分的；在图15中，用于发送抢占信息的资源和用于发送SCI的资源是频分的；在图16中，抢占信息随SCI一起发送，用于发送抢占信息的资源和用于发送SCI的资源是频分的；在图17中，抢占信息随SCI对应的数据一起发送，用于发送抢占信息的资源和用于发送SCI对应的数据的资源是频分的。
需要说明的是，上述图14至图17仅是示例性的说明抢占信息可以随SCI或者SCI对应的数据一起发送，当然，抢占信息随SCI或者SCI对应的数据一起发送的示意图也可以为其它，比如，在图16中，用于发送抢占信息的资源和用于发送SCI的资源也可以是时分的；在图17中，用于发送抢占信息的资源和用于发送SCI对应的数据的资源也可以是时分的，本申请实施例对此不作具体限定。
需要说明的是，上述图10至图17中，在抢占信息随着SCI一起发送的情况下，用于发送抢占信息的资源和用于发送SCI的资源可能是一个资源，也可能是独立的两个资源，也就是说，本申请实施例中的第二资源可以仅用于发送抢占信息，或者，本申请实施例中的第二资源除了可以发送抢占信息之外，还可以发送SCI，本申请实施例对此不作具体限定。
可选的，本申请实施例中，第一通信设备可以根据资源配置参数确定用于发送抢占信息的第二资源，该资源配置参数例如可以包括：第二资源的时域位置信息、第二资源的频域位置信息、或者抢占信息的MCS中的至少一个。此外，该资源配置参数可 以为网络设备配置的参数或者预先配置在第一通信设备上的参数等，本申请实施例对此不作具体限定。
一种可能的实现方式中，该资源配置参数是非固定的，此时，相应的，SCI中还可以包括该资源配置参数，该资源配置参数用于第二通信设备接收该抢占信息。
另一种可能的实现方式中，该资源配置参数是固定的，此时，用于发送抢占信息的时频资源位置是固定的。比如，在图10或图14中，第三个符号用于发送抢占信息；或者，在图11或图15中，PRB序号为3和4的资源用于发送抢占信息，等等。当然，在资源配置参数是固定的情况下，MCS也是固定的，比如，MCS为正交相移键控(quadrature phase shift keying，QPSK)，本申请实施例对此不作具体限定。
再一种可能的实现方式中，该资源配置参数中的第三参数是固定的，第四参数是非固定的，此时，相应的，SCI中还可以包括该第四参数，该第四参数用于第二通信设备接收该抢占信息，本申请实施例对此不作具体限定。
可选的，对于上述方式二，在资源配置参数是固定的情况下，由于第二通信设备上也可以预先配置该资源配置参数，因此可以不用在SCI中携带该资源配置参数，在此统一说明，以下不再赘述。
可选的，对于上述方式二，SCI中还可以包括第一指示信息，该第一指示信息用于指示在预留资源上有抢占信息发送。比如，使用1比特，为1时表示在预留资源上有抢占信息发送，为0时表示在预留资源上没有抢占信息发送。其中，在SCI中包括第一指示信息的情况下，若上述资源配置参数是非固定的，进一步的，在SCI中还可以包括该资源配置参数，这样可以保证第二通信设备及时获知该资源配置参数为用于发送抢占信息的资源配置参数，进而第二通信设备可以根据该资源配置参数接收该抢占信息。
进一步的，对于上述方式二，预留资源中的数据部分发送可以有不同的实现方式，下面将示例性介绍如下。
一种可能的实现方式中，预留资源上的数据包括非突发业务数据，第一资源上的数据包括突发业务数据。比如，以资源池中的资源可以时分的情况为例进行说明，则图14至图17中预留资源上的数据可以为非突发业务数据，第一资源上的数据可以包括突发业务数据，结果分别如图18至图21所示。
另一种可能的实现方式中，预留资源上的数据和第一资源上的数据均包括突发业务数据。比如，以资源池中的资源可以时分的情况为例进行说明，则图14至图17中预留资源上的数据可以为突发业务数据，第一资源上的数据可以包括突发业务数据，结果分别如图22至图25所示。该情况通常适用于如周期性的非突发业务数据已经发送完成，此时有预留资源，但是没有周期性的非突发业务数据要发送的场景下，或者非突发业务数据较大的场景下，等等，本申请实施例对此不作具体限定。
进一步地，本申请实施例中，第一资源上的数据和预留资源上数据可以为整体进行信道编码的数据，也可以为分开进行信道编码的数据，本申请实施例对此不作具体限定。
其中，若第一资源上的数据和预留资源上数据可以为整体进行信道编码的数据，则SCI或者抢占信息中还可以包括第三指示信息，该第三指示信息用于指示第一资源 上的数据和预留资源上的数据是一个传输块(transport block，TB)，或者第三指示信息用于指示第一资源上的数据和预留资源上的数据是联合编码的，或者第三指示信息用于指示第一资源上的数据和预留资源上的数据在接收侧需要联合解码。
或者，若第一资源上的数据和预留资源上数据可以为分开进行信道编码的数据，则SCI或者抢占信息中还包括第三指示信息，该第三指示信息用于指示第一资源上的数据和预留资源上的数据是独立的TB，或者第三指示信息用于指示第一资源上的数据和预留资源上的数据是独立编码的，或者第三指示信息用于指示第一资源上的数据和预留资源上的数据在接收侧需要分开解码，或者第三指示信息用于指示接收侧按照正常方式进行接收。
比如，在SCI或者抢占信息中加入一比特指示，为1时，指示第一资源上的数据和预留资源上的数据是一个TB，或者指示第一资源上的数据和预留资源上的数据是联合编码的，或者指示第一资源上的数据和预留资源上的数据在接收侧需要联合解码；为0时，指示第一资源上的数据和预留资源上的数据是独立的TB，或者指示第一资源上的数据和预留资源上的数据是独立编码的，或者指示第一资源上的数据和预留资源上的数据在接收侧需要分开解码，或者指示接收侧按照正常方式进行接收。
当然，本申请实施例中，若第一资源上的数据和预留资源上数据为分开进行信道编码的数据，即作为两个TB在两个时间单元上分开进行传输，则SCI或者抢占信息中可以无需额外指示，接收侧通信设备可以在两个时间单元上按照两个独立的TB分开进行接收和解码即可，本申请实施例对此不作具体限定。
可选的，本申请实施例中，在第一通信设备恰好有预留资源，且预留资源可以容纳突发业务数据的情况下，也可以如图26至图31所示，直接使用预留资源发送突发业务数据，而不用额外的进行资源抢占，这样可以进一步减小突发业务数据的发送时延，本申请实施例对此不作具体限定。
其中，在图26、图27、图29和图30中，用于发送数据的资源和用于发送SCI的资源属于同一个资源池；在图28和图31中，用于发送数据的资源和用于发送SCI的资源属于不同的资源池，比如，SCI资源池用于发送SCI；数据资源池用于发送数据。其中，在图26和图27中，资源池中的资源是频分的，而图26中，用于发送突发业务数据的资源和用于发送SCI的资源是时分的，图27中，用于发送突发业务数据的资源和用于发送SCI的资源是频分的；在图29和图30中，资源池中的资源是时分的，而图29中，用于发送突发业务数据的资源和用于发送SCI的资源是时分的，图30中，用于发送突发业务数据的资源和用于发送SCI的资源是频分的。
其中，上述方式二相对于方式一的优势在于：一方面，方式二不需要额外的用于发送抢占信息的专用资源，因此减少了资源浪费，提升了资源的利用率；另一方面，由于可以利用预留资源发送突发业务数据，因此使得资源的使用更加灵活。
方式三：第二资源为用于发送SCI的资源中的资源。
也就是说，本申请实施例中，第一通信设备可以使用发送SCI的资源发送抢占信息。比如，在图32中，SCI资源池用于发送SCI，此外，第一通信设备也可以在该SCI资源池中发送抢占信息。由于不需要额外的用于发送抢占信息的专用资源，因此减少了资源浪费，提升了资源的利用率。
需要说明的是，图32以发送SCI的资源和发送抢占信息的资源是频分的为例进行说明，当然，发送SCI的资源和发送抢占信息的资源也可以是时分的，本申请实施例对此不作具体限定。
对于上述方式三，由于SCI资源池既可以用于发送SCI，又可以用于发送抢占信息，因此需要对SCI和抢占信息加以区分。
一种可能的实现方式中，抢占信息或者SCI中加入一个域用于区分二者，如1比特，为0时表示该信息为SCI，为1时表示该信息为抢占信息等。
或者，另一种可能的方式，二者采用不同的加扰序列，比如，如采用不同的序列初始化ID(c init)，序列初始化ID为ID1时表示该信息为SCI，序列初始化ID为ID2时表示该信息为抢占信息等。
对于上述方式一至方式三中的任一方式，可选的，本申请实施例中的资源配置参数中还可以包括一个参数，用于表征在该资源配置参数对应的资源池中是否允许发送突发业务数据。比如，使用1比特，为1时表示允许，为0时表示不允许等。其中，在允许的情况下，第一通信设备才确定用于发送抢占信息的第二资源；在不允许的情况下，第一通信设备确定在该资源配置参数对应的资源池中不发送突发业务数据。这样，一方面，可以避免第一通信设备的突发业务数据传输失败的问题，提高数据传输的可靠性；另一方面，可以避免第一通信设备的数据传输对其它通信设备的数据传输的干扰，提高其它通信设备数据传输的质量。
对于上述方式一至方式三中的任一方式，可选的，本申请实施例中的抢占信息中可以包括现有的SCI中的所有信息，也就是说可以采用现有的SCI的格式发送该抢占信息，此时，在第一资源上发送数据时，可以按照现有的方式，在第一资源上发送数据对应的SCI；也可以在第一资源上不发送SCI，因为抢占信息中已经包括该SCI，本申请实施例对此不作具体限定。或者，可选的，本申请实施例也可以定义一种新的控制信息格式用于发送抢占信息，该抢占信息中仅包括指示第一资源的最少信息，如仅包括必须的第一资源的时域位置信息、第一资源的频域位置信息、或第一资源上数据的优先级等，此时，在第一资源上发送数据时，需要按照现有的方式，在第一资源上发送数据对应的SCI，本申请实施例对此不作具体限定。
其中，本申请实施例步骤S604中：
可选的，若第二资源为步骤S602中的方式一对应的用于发送抢占信息的专用资源集合中的资源，则本申请实施例提供的抢占信息的传输方法还可以包括：第二通信设备根据第一参数确定可用于接收抢占信息的专用资源集合，其中，专用资源集合中包括第二资源；进而，第二通信设备在专用资源集合中的资源上检测抢占信息。本申请实施例中，由于第一通信设备是在第二资源上发送抢占信息的，因此第二通信设备可以在第二资源上检测到抢占信息，进而第二通信设备可以在第二资源上接收该抢占信息。其中，第一参数和专用资源集合的相关描述可参考步骤S602中的方式一，在此不再赘述。
或者，可选的，若第二资源为步骤S602中的方式二对应的第一通信设备的预留资源中的资源，且SCI中包括上述方式二中的第一指示信息，则本申请实施例提供的抢占信息的传输方法还可以包括：第二通信设备根据该第一指示信息，确定在预留资源 上有抢占信息发送。进而，第二通信设备可以在第二资源上接收该抢占信息。具体的，第二通信设备可以根据资源配置参数,在第二资源上接收来自第一通信设备的抢占信息。其中，该资源配置参数的相关描述可参考步骤S602中的方式二中关于资源配置参数的描述，在此不再赘述。
或者，可选的，若第二资源为步骤S602中的方式三对应的用于发送SCI的资源中的资源，且对抢占信息和SCI进行区分的方式为在抢占信息或者SCI中加入一个域用于区分二者，则此时第二通信设备在接收到一个SCI或者抢占信息之后，首先根据这个域判断接收到的是正SCI还是抢占信息，若是SCI，则按照SCI的格式进行解读，若是抢占信息，则按照抢占信息的格式进行解读，本申请实施例对此不作具体限定。
或者，可选的，若第二资源为步骤S602中的方式三对应的用于发送SCI的资源中的资源，且对抢占信息和SCI进行区分的方式为采用不同的加扰序列用于区分二者，则此时第二通信设备在接收到一个SCI或者抢占信息之后，分别尝试用不同的加扰序列进行盲解，若采用SCI的加扰序列盲解成功(如通过了循环冗余校验(cyclic redundant check，CRC)校验)，则按照SCI的格式进行解读，若采用抢占信息的加扰序列盲解成功(如通过了CRC校验)，则按照抢占信息的格式进行解读，本申请实施例对此不作具体限定。
可选的，对应步骤S602中的方式二，若第一资源上的数据和预留资源上数据为整体进行信道编码的数据，则本申请实施例提供的抢占信息的传输方法还可以包括：第二通信设备根据第二指示信息，对第一资源上的数据和预留资源上的数据联合解码。
或者，可选的，对应步骤S602中的方式二，若第一资源上的数据和预留资源上数据为分开进行信道编码的数据，则本申请实施例提供的抢占信息的传输方法还可以包括：第二通信设备根据第二指示信息，对第一资源上的数据和预留资源上的数据分开解码。
其中，本申请实施例步骤S605中：
可选的，如图33所示，若数据在n时刻到达，则第二通信设备需要在[n-1000,n-1]范围(侦听窗)内进行侦听，并根据侦听结果，在[n+T1,n+T2]范围内(资源选择窗)进行资源选择。在第二通信设备正在进行资源选择的情况下，第二通信设备根据抢占信息，对第一资源进行资源躲避，具体可以包括：第二通信设备根据抢占信息，确定第一资源与第二通信设备的备选资源集合中的第三资源有交叠；第二通信设备将第三资源从备选资源集合中排除。比如，如图33所示，当第二通信设备获知资源选择窗内的第三资源与第一资源有交叠，则从备选资源集合中直接排除该第三资源。
需要说明的是，本申请实施中的第一资源和第三资源有交叠可以是部分交叠，也可以是全部交叠，本申请实施例对此不作具体限定。
或者，可选的，在第二通信设备已经选择了第三资源的情况下，第二通信设备根据抢占信息，对第一资源进行资源躲避，具体可以包括：第二通信设备根据抢占信息，确定第三资源与第一资源有交叠；第二通信设备停止在第三资源上发送数据。也就是说，即使第二通信设备已经选择了第三资源，仍要继续检测监听抢占信息。当某一时刻通过抢占信息获知该第三资源已被第一通信设备占用，则第二通信设备停止在第三资源上发送数据。其中，该情况下的第三资源通常为某一个预留资源，在此统一说明， 以下不再赘述。
可选的，本申请实施例提供的抢占信息的传输方法还可以包括：第二通信设备确定第二通信设备占用的资源被连续抢占的次数大于或者等于预设门限；第二通信设备重新进行资源选择。比如，若抢占信息中包括第一通信设备预计占用的次数为4次，预设门限为3，即第二通信设备确定第二通信设备占用的资源被连续抢占的次数大于预设门限，则第二通信设备需要重新进行资源选择；或者，比如，若抢占信息中包括第一通信设备预计占用的次数为4次，预设门限为4，即第二通信设备确定第二通信设备占用的资源被连续抢占的次数等于预设门限，则第二通信设备需要重新进行资源选择。通过资源重新选择，可以避免第二通信设备等待较长的时间所可能导致的业务中断，提升了第二通信设备数据传输的可靠性。
示例性的，如图34所示，在第二通信设备已经选择了第三资源，且第三资源是某一个预留资源的情况下，若第二通信设备根据抢占信息，确定第三资源与第一资源有交叠，且第一通信设备预计抢占的次数为1次，小于预设门限，则第二通信设备不再使用第三资源发送数据，待下一周期的预留资源上再发送数据。
或者，示例性的，如图35所示，在第二通信设备已经选择了第三资源，且第三资源是某一个预留资源的情况下，若第二通信设备根据抢占信息，确定第三资源与第一资源有交叠，且第一通信设备预计抢占的次数为3次，大于或者等于预设门限，则将触发第二通信设备进行资源重选。
需要说明的是，本申请实施例中，第二通信设备可以是在获知第二通信设备占用的资源被连续抢占的次数大于或者等于预设门限时进行资源重选，比如在获取抢占信息，根据抢占信息获知第一通信设备预计占用的次数之后；也可以是在第二通信设备无法获知第一通信设备预计占用的次数的情况下，第二通信设备获知占用的资源已经被连续抢占的次数大于或者等于预设门限时进行资源重选，本申请实施例对此不作具体限定。
基于本申请实施例提供的抢占信息的传输方法，由于第一通信设备可以在确定要占用的第一资源之后，向第二通信设备发送指示第一资源被第一通信设备占用的抢占信息，使得第二通信设备可以获知第一资源被第一通信设备占用，进而对第一资源进行躲避，因此可以在第一通信设备有突发业务时，减少第一通信设备和第二通信设备选择到相同资源的概率，从而提升突发业务数据传输的可靠性。
其中，上述步骤S601至S605中的第一通信设备或者第二通信设备的动作可以由图5所示的通信设备500中的处理器501调用存储器503中存储的应用程序代码来执行，本实施例对此不作任何限制。
综上，因此，本申请实施例公开了一种抢占信息的发送方法，包括：第一通信设备确定要占用的第一资源以及用于发送抢占信息的第二资源，其中，抢占信息用于指示第一资源被第一通信设备占用，第二资源的时域位置在第一资源的时域位置之前；第一通信设备在第二资源上向第二通信设备发送抢占信息。

可选的，本申请实施例公开的抢占信息的接收方法还可以包括：第二通信设备确定第二通信设备占用的资源被连续抢占的次数大于或者等于预设门限；第二通信设备重新进行资源选择。

作为另一种实现，第二资源为第一通信设备的预留资源中的资源。
可选的，预留资源还用于发送SCI，SCI中包括第一指示信息；本申请实施例公开的抢占信息的接收方法还可以包括：第二通信设备根据第一指示信息，确定在预留资源有抢占信息发送。
可选的，SCI中还包括资源配置参数，资源配置参数包括：第二资源的时域位置信息、第二资源的频域位置信息、或者抢占信息的调制编码格式MCS中的至少一个；第二通信设备在第二资源上接收来自第一通信设备的抢占信息，包括：
第二通信设备根据资源配置参数,在第二资源上接收来自第一通信设备的抢占信息。
作为再一种实现，第二资源为用于发送SCI的资源中的资源。
可选的，抢占信息中包括第二指示信息；本申请实施例公开的抢占信息的接收方法还可以包括：第二通信设备根据第二指示信息，确定第二资源上的信息为抢占信息。
或者，可选的抢占信息采用不同于SCI的加扰序列进行加扰；本申请实施例公开 的抢占信息的接收方法还可以包括：第二通信设备根据第二资源上的信息的加扰序列，确定第二资源上的信息为抢占信息。
上述抢占信息的发送方法中，例如，第二通信设备的操作可参考图6中第二通信设备的操作及上述相关文字说明，在此不再赘述。

本申请实施例可以根据上述方法示例对第一通信设备或第二通信设备进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。需要说明的是，本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
比如，以采用集成的方式划分各个功能模块的情况下，图36示出了一种第一通信设备360的结构示意图。该第一通信设备360例如可以包括终端或者终端内的芯片或电路等，本申请实施例对此不作具体限定。其中，该第一通信设备360包括：处理模块3601和收发模块3602。处理模块3601，用于确定要占用的第一资源以及用于发送抢占信息的第二资源，其中，抢占信息用于指示第一资源被第一通信设备占用，第二资源的时域位置在第一资源的时域位置之前；收发模块3602，用于在第二资源上向第二通信设备发送抢占信息。
一种可能的实现方式中，第二资源为用于发送抢占信息的专用资源集合中的资源；处理模块3601具体用于：根据第一参数确定可用于发送抢占信息的专用资源集合；从专用资源集合中确定用于发送抢占信息的第二资源。
另一种可能的实现方式中，第二资源为第一通信设备的预留资源中的资源。
再一种可能的实现方式中，第二资源为用于发送SCI的资源中的资源。
可选的，处理模块3601具体用于：根据接收到的其它终端发送的SCI中指示的业务优先级以及其它终端发送的SCI中指示的资源，确定要占用的第一资源。

由于本申请实施例提供的第一通信设备可用于执行上述抢占信息的传输方法，因此其所能获得的技术效果可参考上述方法实施例，在此不再赘述。
比如，以采用集成的方式划分各个功能模块的情况下，图37示出了一种第二通信设备370的结构示意图。该第二通信设备370例如可以包括终端或者终端内的芯片或电路等，本申请实施例对此不作具体限定。其中，该第二通信设备370包括：处理模块3701和收发模块3702。收发模块3702，用于在第二资源上接收来自第一通信设备的抢占信息，抢占信息用于指示第一资源被第一通信设备占用，其中，第二资源的时域位置在第一资源的时域位置之前；
