  • Authorized transmission In the wireless cellular network, before the terminal sends uplink data, it usually needs to establish a radio resource control (RRC) connection with the base station, enter the radio resource control connection (RRC_CONNECTED) state, and then the terminal sends to the base station Scheduling request (SR). If the base station allows the terminal to send uplink data, the base station sends an authorization instruction to the terminal. In this way, after receiving the authorization instruction, the terminal sends uplink data according to the authorization instruction. In this uplink data sending method, the terminal needs to be authorized by the base station to send the uplink data, so it is called authorized transmission.

  • the delay here refers to the delay when the terminal determines that there is uplink data to be sent to the terminal to send the uplink data out of the air interface; the other disadvantage is that when a certain period of time When there are a large number of terminals that need to send uplink data within a time, the uplink and downlink control channel resources used to send scheduling requests and authorization instructions consume a lot, resulting in a higher proportion of control overhead in the total network overhead (such as power, air interface resources, etc.), especially This shortcoming of authorized transmission is particularly obvious when the terminal's services are all small data packet services.
  • Grant free scheduling In this scheduling mode, when the terminal determines that there is uplink data to be sent, it does not have to go through the process of sending an uplink scheduling request and waiting for the authorization of the receiving base station, but directly sends the processed data. Upstream data. Compared with authorized transmission, authorization-free scheduling can shorten the transmission delay of the terminal.

Description

资源指示方法及装置
本申请要求于2019年08月23日提交国家知识产权局、申请号为201910785962.5、发明名称为“资源指示方法及装置”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
本申请涉及通信技术领域，尤其涉及资源指示方法及装置。
背景技术
随着无线通信技术的发展，人们对了解周边人或事物并与之通信的需求逐渐增加，因此，设备到设备(device to device，D2D)技术应运而生。D2D技术允许多个支持D2D功能的设备之间进行直接发现和直接通信。但是，车联网需求极高的安全性，且时延要求较高，目前基于D2D技术还无法实现较低时延，因此无法满足车联网需求。
为了提升车联网的安全性，在第三代合作伙伴计划(the 3rd generation partnership project，3GPP)提出的基于长期演进(long term evolution，LTE)技术的网络中，车与任何事物通信(vehicle-to-everything，V2X)的车联网技术被提出。V2X通信是指车辆与外界的任何事物的通信，如图1所示，V2X包括车与车的通信(vehicle to vehicle，V2V)、车与行人的通信(vehicle to pedestrian，V2P)、车与基础设施的通信(vehicle to infrastructure，V2I)、车与网络的通信(vehicle to network，V2N)。在V2X中，不同于终端与基站之间的上行(uplink，UL)和下行(downlink，DL)传输，设备之间可以进行直接传输，在3GPP设备之间的直连链路被定义为侧行链路(sidelink，SL)。
在LTE V2X中，针对周期业务，终端可以采用长期测量(long term sensing，LTS)机制预约通信资源，以降低和其他终端之间的资源碰撞。具体的，终端周期性发送数据，且终端发送侧行链路控制信息(sidelink control information，SCI)，SCI指示该终端发送上述数据所占用的时频资源。终端还需侦听其他终端的SCI，以获知已被其他终端占用的时频资源。如此，当该终端发送数据时，能够排除已被其他终端占用的时频资源，在空闲资源上选择用于发送周期业务数据的时频资源，并在所选择时频资源上发送数据。终端还可以发送SCI，将自身占用的时频资源告知其他终端。
但是现存的资源预约机制只能减少终端之间与周期业务的资源碰撞的概率。

具体实施方式
本申请的说明书以及附图中的术语“第一”和“第二”等是用于区别不同的对象，或者用于区别对同一对象的不同处理，而不是用于描述对象的特定顺序。此外，本申请的描述中所提到的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、***、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括其他没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。需要说明的是，本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
首先，对本申请实施例涉及的技术术语进行介绍：
1、资源单元(resource element，RE)：以图6为例，频率上一个子载波及时域上一个符号(symbol)，称为一个RE。RE可以用于承载信息，比如，承载数据或信令。
SL的两种资源分配方式：
1、模式3(mode 3)：参见图2中(a)，该模式3主要应用在有网络覆盖情况下的V2X通信。基站根据终端上报的缓存状态(buffer status report，BSR)，进行资源分配。终端根据基站的调度授予，在被调度的时频资源上进行V2X通信。其中，调度请求、调度授予使用基站和终端之间的上下行链路，终端之间的直接通信使用SL。
2、模式4(mode 4)：参见图2中(b)，终端在预配置的V2X资源池中选择时频资源，并在选择的时频资源上进行V2X通信。
3、授权传输：无线蜂窝网络中，终端在发送上行数据之前，通常需要建立与基站的无线资源控制(radio resource control，RRC)连接，进入无线资源控制连接(RRC_CONNECTED)状态，然后终端向基站发送调度请求(scheduling request，SR)。如果基站允许该终端发送上行数据，基站向该终端发送授权指令。如此，终端接收到授权指令后，根据授权指令发送上行数据。这种上行数据发送方法中，终端需得到基站的授权才可发送上行数据，因此称为授权传输。授权传输有两个缺点，一个是时延比较大，这里的时延是指，从终端确定有上行数据需要发送到终端从空口将上行数据发送出去的时延；另一个缺点是，当某段时间 内需发送上行数据的终端数量较多时，用于发送调度请求和授权指令的上下行控制信道资源消耗较大，导致控制开销占网络总开销(如功率、空口资源等)的比例较高，尤其是当终端的业务都是小数据包业务时，授权传输的这一缺点尤为明显。
4、免授权调度(grant free，GF)：在这种调度方式中，终端确定有上行数据要发送时，不必经过发送上行调度请求和等待接收基站的授权这一过程，而是直接发送经处理的上行数据。相比于授权传输，免授权调度可以缩短终端的传输时延。
本申请实施例提供的资源指示方法主要应用在无网络覆盖的场景中。参见图3，为本申请实施例所涉及的通信***，该通信***包括终端设备和网络设备。其中，上述终端设备，可以通过空口连接到网络设备，以便接收网络服务。上述网络设备主要用于实现无线物理层功能、资源调度和无线资源管理、无线接入控制以及移动性管理功能。
此外，上述终端设备之间也可以通过SL直接进行通信，如进行V2X通信。容易理解的是，上述通过SL直接通信所使用的资源池，可以是网络设备配置的资源池，如终端设备与网络设备的空口连接正常时所使用的资源池，也可以是终端设备中预配置的资源池，如设备厂商在终端设备出厂前根据协议规定事先配置在终端设备中的资源池。
示例性的，上述终端设备通过SL直接通信，可以是上述提及的V2V、V2I、V2N、V2P通信等，也可以是终端设备之间其他形式的直接通信，如行人到行人(pedestrian to pedestrian，P2P)通信。
此外，除SL外，终端设备之间的直接通信也可以采用其他形式或其他名称的无线连接，如未来的无线通信***，6G***等，本申请对此不作限定。
其中，该网络设备包括但不限于：Wi-Fi***中的接入点(access point，AP)，如家用无线路由器、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)，eNB、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(baseband unit，BBU)，还可以为5G***，如NR中的gNB，或，传输点(TRP或TP)，5G***中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层和服务发现应用规范(service discovery application profile，SDAP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，在此不做限制。
示例性的，上述终端设备也可以称为站点(station，STA)、用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。上述终端设备包括但不限于：手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、车联网中终端(比如汽车终端)、传感器类设备，如监控终端等。本申请的终端设备还可以是作为一个或多个部件或者单元而内置于车辆的车载模块、车载模组、车载部件、车载芯片或者车载单元，车辆通过内置的车载模块、车载模组、车载部件、车载芯片或者车载单元可以实施本申请的方法。
应理解，图3仅为便于理解而示例的简化示意图，仅示出了终端设备和网络设备(比如基站)。在本申请实施例中，该无线通信***中还可以包括其他网络设备或者还可以包括其他终端设备，图3中未予以画出。
可选的，本申请实施例中的终端设备、网络设备可以分别由多个设备实现，例如，终端设备为一个设备，网络设备为一个设备，还可以将终端设备功能和网络设备功能集成在一个设备内，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，本申请实施例中的终端设备、网络设备可通过图4中的通信设备来实现。图4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200包括至少一个处理器201，存储器203以及至少一个收发器204。
处理器201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。
收发器204，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。收发器204可以集成发送和接收信息的功能，收发器也可以指收发器或接收器。其中，发送器可以包括天线和射频电路等，接收器可以包括天线和射频电路等。
存储器203可以是只读存储器(read-only memory，ROM)或可存储静态信息和指令的其他类型的静态存储设备，随机存取存储器(random access memory，RAM)或者可存储信息和指令的其他类型的动态存储设备，也可以是电可擦可编程只读存储器(electrically erasable programmable read-only memory，EEPROM)、只读光盘(compact disc read-only memory，CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质，但不限于此。存储器可以是独立存在，并能够与处理器相连接。存储器也可以和处理器集成在一起。
其中，存储器203用于存储执行本申请方案的计算机执行指令，并由处理器201来控制执行。处理器201用于执行存储器203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资源指示方法。
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201可以包括一个或多个CPU，例如图4中的CPU0和CPU1。
在具体实现中，作为一种实施例，通信设备200可以包括多个处理器，例如图4中的处理器201和处理器207。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200还可以包括输出设备205和输入设备206。输出设备205和处理器201通信，可以以多种方式来显示信息。例如，输出设备205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206和处理器201通信，可以以多种方式接收用户的输入。例如，输入设备206可以是鼠标、键盘、触摸屏设备或传感设备等。图4中的各个组件之间相互连接。
上述的通信设备200可以是一个通用设备或者是一个专用设备。终端设备、网络设备为有图4中类似结构的设备。本申请实施例不限定通信设备200的类型。
以下结合图3所示的通信***，说明本申请实施例提供的资源指示方法。下文主要以网络设备为基站为例进行说明，在此统一声明，下文不再赘述。
本申请实施例提供一种资源指示方法，参见图5，该方法包括如下步骤：
S501、第一终端设备接收非周期资源参数。
需要说明的是，步骤S501是可选的，一种情况下上述非周期资源参数为预配置的，比如，终端设备出厂时，厂商依据相关协议标准预配置在终端设备中，此时不存在步骤S501。
非周期资源参数可以是从网络设备接收的，或者也可以是从其他终端设备接收的。作为一种可能的实现方式，网络设备或其他终端设备向第一终端设备发送第一信令，第一信令携带非周期资源参数。如此，第一终端设备从网络设备或其他终端设备接收第一信令，根据第一信令所指示的非周期资源参数确定所使用的第二时频资源。其中，第一信令为RRC消息或下行控制信息(downlink control information，DCI)。
其中，非周期资源参数用于第一终端设备确定用于发送非周期业务数据的第二时频资源。本申请实施例中，某一终端设备的第二时频资源，指的是该终端设备用于发送非周期业务数据的时频资源。类似的，本申请实施例中，某一终端设备的第一时频资源，指的是该终端设备用于发送周期业务数据的时频资源，在此统一说明，下文不再赘述。
非周期资源参数包括参考时频资源大小和第一时频偏移，第一时频偏移为周期业务数据的一个周期中用于发送非周期业务数据的时频资源与用于发送周期业务数据的时频资源之间的时频起始位置的偏移。时频起始位置的偏移包括时域起始位置的偏移和/或频域起始位置的偏移。即，时频起始位置可以是时域起始位置的偏移，也可以是频域起始位置的偏移，还可以指时域起始位置的偏移和频域起始位置的偏移。第一时频偏移用于指示一个周期中第二时频资源与第一时频资源之间的相对位置关系。参考时频资源包括一个或多个时频资源单元。时频资源单元包括一个或多个RE。第一终端设备的参考时频资源为预配置或基站配置的可以用于第一终端设备发送非周期业务数据的时频资源的集合。第一终端 设备的参考时频资源和第一终端设备实际发送非周期业务数据的资源可能不同。第一终端设备可以在参考时频资源上选取用于发送非周期业务数据的资源，当参考时频资源不足以支持第一终端设备发送非周期业务数据时，第一终端设备还可以抢占其他资源用于发送非周期业务数据。其中，参考时频资源大小可以由基站根据终端设备的业务统计情况，***带宽，用户设备数量等参数确定。比如，若***带宽较大，则基站可以为每一终端设备分配更多的参考时频资源，以提升终端设备的业务成功率。若网络中用户设备数目较多，则基站可以为每一终端设备配置较少的参考时频资源，以满足更多终端设备的通信需求。若基站根据某一终端设备的业务统计情况，发现该终端设备每次收发数据包的数据量较大，则可以为该终端设备配置较多的参考时频资源。
可选的，当一个周期中第一时频资源的时频起始位置与第二时频资源的时频起始位置在时域上存在偏移，在频域上不存在偏移时，非周期资源参数可以仅包括两个时频起始位置之间的时域偏移，不包括两个时频起始位置之间的频域偏移。如此，通过非周期资源参数可以显示指示两个时频起始位置之间的时域偏移，并隐式指示两个时频起始位置之间的频域偏移，以便于终端设备获知一个周期中第二时频资源与第一时频资源之间的位置关系。并且，由于该非周期参数可以不显示包括两个时频起始位置之间的频域偏移，所以当非周期资源参数是预存储在终端设备中，则可以降低终端设备存储资源的消耗。若非周期资源参数是通过基站配置给该终端设备的，则可以降低基站的信令开销。
类似的，当一个周期中第一时频资源的时频起始位置与第二时频资源的时频起始位置在时域上不存在偏移，在频域上存在偏移时，非周期资源参数可以仅包括两个时频起始位置之间的频域偏移，不包括两个时频起始位置之间的时域偏移。
可选的，参考时频资源包括一个时频资源单元。以图6为例，终端设备的非周期资源参数如下：{参考时频资源大小：3个RE；第一时频偏移：一个周期中第一时频资源的时频起始位置与第二时频资源的时频起始位置在时域上相差3个符号，在频域上不存在偏移}。这就意味着，终端1可以在图6所示的在一个周期中配置的第二时频资源上发送非周期业务数据。
可选的，参考时频资源包括多个(即两个或两个以上)时频资源单元。非周期资源参数还包括相邻两个时频资源单元之间的时间间隔、时频资源单元的大小、时频资源单元的个数。以图7为例，终端1的非周期资源参数如下：{参考时频资源大小：6个RE；第一时频偏移：一个周期内，相比于第一时频资源的时频初始位置，第二时频资源的时频初始位置在时域上延迟1个符号；时频资源单元的大小：2个RE；相邻两个时频资源单元之间的时间间隔：4个符号}。按照图7所示的资源配置方式，当终端1有非周期业务数据需发送时，其可以在多个周期中配置的6个RE上发送该非周期业务数据。当然，图7是以周期业务数据的相邻周期均配置第二时频资源为例，在实际应用中，还可以是间隔配置第二时频资源，比如，周期业务数据的第一个周期配置第二时频资源，第二个周期不配置第二时频资源，第三个周期配置第二时频资源。具体的，结合图7，若相邻时频资源单元之间的时间间隔配置为8个符号，则意味着第二个周期不配置第二时频资源。
可选的，非周期资源参数还可以包括时频资源单元中多个RE或REG的时频位置。
作为一种可能的实现方式，上述非周期资源参数均可以根据终端设备的业务统计情况、***带宽、网络中用户设备数目中的一个或多个因素确定。每一非周期资源参数参考的因 素可以相同或者不同。比如，上述的每一非周期资源参数均根据终端设备的业务统计情况和***带宽确定。在实际实现中，也可以是，一部分非周期资源参数(比如参考时频资源大小、第一时频偏移)根据终端设备的业务统计情况确定，另外部分非周期资源参数根据***带宽和用户设备数目确定。
需要说明的是，网络设备可以为所服务的多个终端设备配置相同的非周期资源参数，或者，网络设备可以针对不同终端设备配置不同的非周期资源参数。
需要说明的是，步骤S501可以是上述通信设备的收发器或处理器控制收发器实现。
S502、第一终端设备确定用于发送周期业务数据的第一时频资源。
作为一种可能的实现方式，第一终端设备检测一个或多个第二终端设备的一个或多个资源指示信息，并基于该一个或多个资源指示信息和/或非周期资源参数，确定第一终端设备的第一时频资源。其中，第二终端设备为除第一终端设备之外的终端设备。具体的，第一终端设备基于侦听的一个或多个资源指示信息，确定所使用的第一时频资源。或者，第一终端设备基于侦听的一个或多个资源指示信息，以及非周期资源参数，预约所使用的第一时频资源。关于这两种确定第一时频资源的方式具体描述参见下文。
对于某一第二终端设备来说，该第二终端设备发送周期性业务数据，并发送SCI，SCI包括该第二终端设备的资源指示信息，该资源指示信息用于指示该第二终端设备的第一时频资源，和/或第二终端设备的第二时频资源。具体的，资源指示信息用于指示该第二终端设备的第一时频资源，或者，该该资源指示信息用于指示该第二终端设备的第一时频资源和第二时频资源。这两种资源指示信息的详细介绍可参见下文。第一终端设备侦听(sense)来自其他终端设备(即多个第二终端设备)的资源指示信息，基于侦听的一个或多个资源指示信息，和/或非周期资源参数，排除已被其他终端设备占用的第一时频资源和第二时频资源，在未被其他终端设备占用的时频资源中选取所使用的第一时频资源，以便于发送周期业务数据。
上文已指出，不同终端设备可以有不同或相同的非周期资源参数，并且这两种情况下，第一终端设备确定第一时频资源的方式不同。如下分别以终端设备的非周期资源参数相同或不同这两种情况，详细阐述第一终端设备如何确定第一时频资源。
情况1、终端设备的非周期资源参数均相同。非周期资源参数包括参考时频资源大小、第一时频偏移。可选的，非周期资源参数还包括参考时频资源大小、第一时频偏移、参考时频资源。
上文已指出，终端设备的非周期资源参数用于指示一个周期内第二时频资源与第一时频资源之间的关系，以便于终端设备基于已获知的第一时频资源计算所使用的第二时频资源。如此，当不同终端设备的非周期资源参数均相同时，说明不同终端设备的第二时频资源与第一时频资源之间具有类似的关系。具体的，以终端设备1和终端设备3具有相同的非周期资源参数举例，这两个终端设备的非周期资源参数均如下：{参考时频资源大小：6个RE；第一时频偏移：一个周期内，相比于第一时频资源的时频初始位置，第二时频资源的时频初始位置在时域上延迟1个符号；时频资源单元的大小：2个RE；相邻两个时频资源单元之间的时间间隔：4个符号}，该非周期资源参数对应的资源配置方式可以参考图7所示，终端设备1和终端设备3均被配置相同个数的可用于发送非周期业务数据的资源(即参考时频资源)，即6个RE；参考时频资源均包括3个时频资源单元；每一时频资源 单元均包括2个RE；在一个周期内，第二时频资源与第一时频资源之间的相对位置关系均相同；相邻两个时频资源单元之间的时间间隔均为4个符号。
可选的，第二终端设备的资源指示信息可以仅指示第二终端设备的第一时频资源。此时，由于第一终端设备和第二终端设备的非周期资源参数相同，则第一终端设备可以根据第二终端设备的第一时频资源和自身的非周期资源参数(相当于第二终端设备的非周期资源参数)，比如，第一时频资源与第二时频资源之间的第一时频偏移、时频资源单元大小等参数，计算第二终端设备的第二时频资源。之后，第一终端设备排除已被其他第二终端设备占用的时频资源，在资源池中除其他第二终端设备的第一时频资源和第二时频资源之外的资源，即第一终端设备的第一时频资源包括资源池中一个或多个资源指示信息指示的资源(即一个或多个第二终端设备的第一时频资源)以及非周期资源参数和一个或多个资源指示信息联合指示的资源(即一个或多个第二终端设备的第二时频资源)之外的资源。比如，参见图6，第一终端设备排除终端1和终端2占用的第一时频资源和第二时频资源，在其余资源上选取第一时频资源，选取的第一时频资源即黑色填充的RE。如此，能够降低和其他终端设备之间出现资源碰撞现象的概率。并且，第二终端设备在资源指示信息中不必指示自身的第二时频资源，降低了终端设备之间的信令开销。
可选的，第二终端设备的资源指示信息还可以既指示第二终端设备的第一时频资源，又指示第二终端设备的第二时频资源。第一终端设备的第一时频资源包括资源池中一个或多个资源指示信息指示的资源之外的资源。这种情况下，第一终端设备不必自身计算第二终端设备的第二时频资源，可以降低第一终端设备的计算复杂度，进一步的，能够降低第一终端设备的功耗。
情况2、不同终端设备的非周期资源参数可以不同。
这种情况下，第二终端设备的资源指示信息既指示第二终端设备的第一时频资源，又指示第二终端设备的第二时频资源。同样的，第一终端设备可以由资源指示信息直接获知第二终端设备的第二时频资源和第一时频资源，进而排除这部分资源，在除第二终端设备的第一时频资源和第二时频资源之外的资源上选取所使用的第一时频资源。
作为一种可能的实现方式，第二终端设备所使用的第二时频资源包括一个或多个时频资源单元，第二终端设备的资源指示信息包括如下参数的一种或多种，该一种或多种参数用于指示第二终端设备的第二时频资源：(1)第二终端设备所使用的第二时频资源与第二终端设备所使用的第一时频资源之间的第一时频偏移、(2)时频资源单元的大小、(3)时频资源单元中多个RE之间的时频位置的偏移。
作为另一种可能的实现方式，第二终端设备所使用的第二时频资源包括两个或两个以上时频资源单元，第二终端设备的资源指示信息包括如下参数的一种或多种，该一种或多种参数用于指示第二终端设备的第二时频资源：(1)第二终端设备所使用的第二时频资源与第二终端设备所使用的第一时频资源之间的第一时频偏移、(2)时频资源单元的大小、(3)时频资源单元中多个RE之间的时频位置的偏移、(4)第二终端设备用第二时频资源包括的时频资源单元的个数、(5)第二终端设备所使用的第二时频资源中相邻两个时频资源单元的时间间隔。
需要说明的是，不同终端设备的部分参数可以相同。如此，第二终端设备在资源指示信息中仅需指示与其他终端不同的参数即可。比如，不同终端设备的(1)-(4)参数均相 同，则第二终端设备在资源指示信息中仅需指示(5)参数。如此，第一终端设备可以根据自身的(1)-(4)参数和第二终端设备的(5)参数，确定第二终端设备的第二时频资源。并且，能够降低终端设备发送资源指示信息的信令开销。
其中，上述第一时频偏移为第二终端设备的周期业务数据的一个周期中，第二终端设备所使用的第二时频资源的时频起始位置相对于第二终端设备的第一时频资源的时频起始位置的偏移，该第一时频偏移用于指示第二终端设备的第二时频资源。
与上述第一终端设备具有参考时频资源类似，第二终端设备也被配置有参考时频资源，该参考时频资源为预配置或由基站配置给第二终端设备。当第二终端设备有非周期业务数据发送时，第二终端设备可以在整个参考时频资源上发送该非周期业务数据，也可以在参考时频资源的部分资源上发送该非周期业务数据，或者，当参考时频资源不足以发送该非周期业务数据时，第二终端设备还可以在参考时频资源以及其他资源上发送该非周期业务数据。上述第二终端设备所使用的第二时频资源，指的是第二终端设备实际发送非周期业务数据占用的时频资源，而并非参考时频资源。
作为一种可能的实现方式，第二终端设备发送周期业务数据，并在指示用于发送该周期业务数据的第一时频资源的资源指示信息中，指示其参考时频资源相关的信息，比如，参考时频资源大小、第一时频偏移、参考时频资源包括的时频资源单元的个数、时频资源单元的大小、相邻两个时频资源单元之间的时间间隔中的一个或多个信息。
作为另一种可能的实现方式，若在非周期业务数据到达至该非周期业务数据发送的时间段内存在周期业务数据，则第二终端设备在指示该周期业务数据的第一时频资源的资源指示信息中指示其实际所使用的时频资源的相关信息。第二终端设备实际所使用的第二时频资源与该非周期业务数据的大小有关。比如，以图7中的终端1为例，t0时刻有非周期业务数据到达，t1时刻有周期业务数据发送，则终端1发送资源指示信息来指示该周期业务数据的第一时频资源，并在该资源指示信息中指示实际发送该非周期业务数据的第二时频资源，比如，该非周期业务数据较小，在实际发送该非周期业务数据时仅需占用一个RE(而配置的参考时频资源大小为3个RE)，则在该资源指示信息中指示该实际使用的第二时频资源，即该一个RE。如此，第二终端设备可以指示其实际非周期业务数据占用的时频资源，使得第一终端设备在排除资源时，能够准确排除第二终端设备实际非周期业务数据的时频资源，降低第一终端设备和第二终端设备产生资源碰撞的概率。
可选的，在上述情况1和情况2中，第二终端设备的资源指示信息还用于指示时频资源单元中包括的资源单元或资源单元组(resource element group，REG)之间的优先级。参见图6，终端1的时频资源单元包括3个RE，其中，标记数字1的两个RE为一个REG，该REG的优先级为1，标记数字2的RE的优先级为2。优先级2大于优先级1。RE或REG之间的优先级用于第一终端设备抢占时频资源。在一种可能的实现方式中，当第一终端设备的第二时频资源不足以支持发送非周期业务数据时，第一终端设备可以抢占第二终端设备的第二时频资源中优先级满足第二预设条件的资源。第二预设条件可以指第二终端设备的第二时频资源中优先级最低的资源，也可以是优先级小于或等于某一阈值的资源，还可以是其他类似条件。
需要说明的是，步骤S502可以是由上述通信设备的处理器实现。
S503、第一终端设备确定用于发送非周期业务数据的第二时频资源。
具体的，第一终端设备根据非周期资源参数确定用于发送非周期业务数据的第二时频资源。其中，非周期资源参数包括参考时频资源大小。
若空闲资源大小大于参考时频资源大小，第一终端设备根据非周期资源参数从空闲资源确定第二时频资源。若空闲资源大小小于或等于参考时频资源大小，第一终端设备根据非周期资源参数从空闲资源和一个或多个第二终端设备的用于发送非周期业务数据的时频资源确定第二时频资源。
其中，若一个或多个资源指示信息指示一个或多个第二终端设备的第一时频资源和第二时频资源，空闲资源，指的是资源池中除一个或多个资源指示信息指示的时频资源(即第一或多个第二终端设备的第一时频资源和第二时频资源)和第一时频资源之外的资源。
若一个或多个资源指示信息仅指示一个或多个第二终端设备的第一时频资源，空闲资源，指的是资源池中除一个或多个资源指示信息指示的时频资源(即第一或多个第二终端设备的第一时频资源和第二时频资源)、由非周期资源参数和一个或多个资源指示信息联合确定的用于一个或多个第二终端设备发送非周期业务数据的资源(即一个或多个第二终端设备的第二时频资源)和第一时频资源之外的资源。
以图6为例，空白的RE为空闲资源。对于第一终端设备来说，其参考时频资源为8个RE，即第一终端设备总共被配置有8个可用于发送非周期业务数据的RE，如图6所示，空闲资源(即空白RE)的大小大于或等于8个RE，说明空闲资源足以支持第一终端设备发送非周期业务数据，则第一终端设备在空闲资源(即空白RE)上选取所使用的第二时频资源，即占用空闲资源的部分资源发送非周期业务数据。在其他示例中，空闲资源大小可能小于8个RE，说明空闲资源可能不足以支持第一终端设备发送非周期业务数据，则第一终端设备除占用空闲资源用于发送非周期业务数据之外，还抢占第二终端设备的第二时频资源。如此，第一终端设备可以在抢占的第二终端设备的第二时频资源和空闲资源上发送非周期业务数据，能够为第一终端设备提供充足的用于发送非周期业务数据的时频资源，降低非周期业务数据发送失败的概率。
作为一种可能的实现方式，第一终端设备抢占第二终端设备的第二时频资源中信道忙碌比率(，CBR)满足第一预设条件的第二终端设备的第二时频资源，或者，第一终端设备的第二时频资源包括第二终端设备的优先级满足第二预设条件的第二时频资源。第一预设条件可以是第二终端设备的第二时频资源中CBR最低的预设数目的资源，换言之，第一终端设备的第二时频资源的CBR小于空闲资源中除该第二时频资源外的其他资源的CBR。第一预设条件也可以是CBR小于或等于第一阈值的资源。或者，第一预设条件还可以是其他条件。第二预设条件的详细介绍可参见上文，这里不再赘述。
可选的，第一终端设备的第二时频资源包括至少一个(即一个或多个)时频资源单元。可选的，第一终端设备的非周期资源参数还包括第一时频偏移。第一终端设备在预约第一时频资源后，当余下的空闲资源足够支持第一终端设备发送非周期业务数据时，第一终端设备可以根据第一时频偏移确定第二时频资源与第一时频资源的之间的时频位置的关系，进而确定第二时频资源的时频位置。当然，也存在空闲资源足够支持第一终端设备发送非周期业务数据，但是，空闲资源上不存在与第一时频资源之间满足第一时频偏移的时频资源。此种情况下，为了保证第一终端设备有充足的时频资源使用，第一终端设备可从空闲资源上随机选取所使用的第二时频资源，选取的第二时频资源不必与第一时频资源之间具 有第一时频偏移的关系。或者，第一终端设备从空闲资源上选取与第一时频资源之间的时频偏移最接近第一时频偏移的第二时频资源。
在第一终端设备预约第一时频资源后，当余下的空闲资源不足以支持其发送非周期业务数据时，作为一种可能的实现方式，第一终端设备占用全部的空闲资源，并且抢占第二终端设备的第二时频资源中与第一时频资源之间的时频偏移最接近第一时频偏移的预设个数的第二时频资源。或者，第一终端设备抢占CBR满足上述第一预设条件的预设个数的第二时频资源。或者，抢占优先级满足上述第二预设条件的第二时频资源。或者，结合上述抢占方式，比如，抢占部分CBR较低的第二时频资源，抢占部分优先级较低的第二时频资源。或者，采取其他抢占方式抢占第二终端设备的第二时频资源。
可选的，第一终端设备的第二时频资源包括至少两个(两个或两个以上)时频资源单元。进一步的，第一终端设备的非周期资源参数还包括第一时频偏移、相邻两个时频资源单元之间的时间间隔、时频资源单元的大小中的一项或多项。
需要说明的是，步骤S503可以是上述通信设备的处理器实现。
S504、第一终端设备发送资源指示信息。
第一终端设备的资源指示信息用于指示第一终端设备的第一时频资源，和/或第一终端设备的第二时频资源。也就是说，第一终端的资源指示信息可以仅指示第一终端设备的第一时频资源，还可以既指示第一终端设备的第一时频资源，又指示第一终端设备的第二时频资源。在一种可能的使用资源指示信息指示第二时频资源的实现方式中，资源指示信息包括参考时频资源大小、第一时频偏移。可选的，资源指示信息还包括第一终端设备的参考时频资源包括的时频资源单元的个数、相邻两个时频资源单元之间的时间间隔、时频资源单元的大小。或者，在另一种可能的使用资源指示信息指示第二时频资源的实现方式中，资源指示信息包括第一终端设备实际所使用第二时频资源的大小、第一时频偏移。可选的，资源指示信息还包括第一终端设备的实际第二时频资源包括的时频资源单元的个数、相邻两个时频资源单元之间的时间间隔、时频资源单元的大小。终端设备被配置的参考时频资源和终端设备实际使用的第二时频资源之间的区分与联系，在上文中已详细做出解释，这里不再赘述。
需要说明的是，步骤S504可以是上述通信设备的收发器实现。
S505、第一终端设备在第一时频资源上发送周期业务数据，在第二时频资源上发送非周期业务数据。
需要说明的是，步骤S505可以是上述通信设备的收发器实现。
