Description

终端通信方法及通信设备 技术领域
本申请涉及通信技术，尤其涉及一种终端通信方法及通信设备。
背景技术
基于蜂窝网络的设备到设备(Device-to-Device，D2D)通信，在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)中又称为邻近服务(Proximity Service，ProSe)，是一种在系统的控制下，允许终端之间通过复用小区资源直接进行通信的新型技术，它能够增加蜂窝通信系统频谱效率，降低终端发射功率，在一定程度上解决无线通信系统频谱资源匮乏的问题。为了提升交通系统的安全性和智能化，新兴的智能交通会应用到D2D通信，具体地，智能交通系统的开发将主要集中在智能公路交通系统领域，也就是俗称的车联网(vehicle to everything，V2X)，其中，车对基础设施(vehicle to infrastructure，V2I)和车对车(vehicle to vehicle，V2V)统称为V2X。V2X技术允许汽车与所有附近其它汽车及道路基础设施进行连续通信，比如与红绿灯、校区和铁路道口等设施之间通信。汽车所采用的通信设备可以是车内嵌入式远程信息处理系统，或者是智能手机等移动设备。V2X是未来智能交通运输系统的关键技术，它将使得车与车、车与基站、基站与基站之间能够通信，从而获得实时路况、道路信息、行人信息等一系列交通信息，以提高驾驶安全性、减少拥堵、提高交通效率、提供车载娱乐信息等。
目前，基于D2D通信实现的V2X，终端的业务流量是有周期性的，在V2X技术中增加了终端资源预留方案，即终端可以通知其他终端预留未来某个时频资源，当然终端也要考虑其他终端的预留资源。其中，支持的D2D的终端既需要在侧向链路(sidelink)上进行发送或接收，又需要在上行链路(uplink，UL)上进行发送或在下行链路(downlink，DL)上进行接收。在终端只有一条发送链路时，终端不能同时在sidelink和UL发送信号。类似地，在终端只有一条发送链路时，终端不能同时在sidelink和DL接收信号。现有技术中，在D2D发现(D2D discovery)中定义了间隔(gap)机制来避免冲突，如果终端被配置了接收gap，并且需要gap来监听侧向链路发现通知(sidelink discovery announcements)，则终端使用配置的gap来监听sidelink discovery announcements。类似地，如果终端被配置了发送gap，并且需要gap来发送sidelink discovery announcements，则终端使用配置的gap来发送sidelink discovery announcements。给终端配置gap时，在D2D discovery中用gap周期、gap偏移量和gap子帧比特图(gap subframe bitmap)来指示一个gap图样。gap周期表示gap subframe bitmap重复的周期，gap偏移量表示gap图样第一个周期的起始相对于系统帧号(system frame number，SFN)0的起始的偏移量，gap subframe bitmap是一个比特串，其中值1的位表示终端被允许使用对应的子帧进行sidelink discovery操作，这样基站可以在其他子帧调度终端的UL操作或DL操作，不与终端的sidelink操作冲突。
但是，采用现有技术，指示发送gap时，gap subframe bitmap中每个比特位只能对应唯一子帧，导致开销过大。

具体实施方式
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解：
基站：又称为无线接入网(Radio Access Network，RAN)设备，是一种将终端接入到无线网络的设备，可以是全球移动通讯(Global System of Mobile communication，GSM)或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)中的基站(NodeB，NB)，还可以是长期演进(Long Term Evolution，LTE)中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者未来5G网络中的基站等，在此并不限定。
终端：可以是无线终端也可以是有线终端，无线终端可以是指向用户提供语音和 /或其他业务数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device or User Equipment)，在此不作限定。
本申请中，“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。
针对基于D2D通信实现的V2X，即终端和终端可以直接通信，V2X中终端的业务流量是有周期性的，比如，协同感知信息(Cooperative Awareness Message，CAM)消息，最短周期是100毫秒(ms)，最长周期是1秒(s)。终端有能力预知其流量的周期性，在V2X中增加了终端资源预留的方案，终端可以告知其他终端它要预留未来某个时频资源。另一方面，终端在选择发送数据的时频资源时，要考虑到其他终端在预留的资源，尽量避免其他终端已经预留的资源，也就是终端在选择时频资源时要进行监测。目前的方案中，终端选择Y个子帧作为可能的候选资源，对于Y个子帧中的任意子帧n，UE需要监测子帧n-100*k，k为第一参数。其中，Y的最小值和k的取值集合是预配置或者网络侧设备配置的。目前标准中k的取值范围是[1，10]，[1,10]表示集合(1,2,3,4,5,6,7,8,9,10)。当配置k＝1,10时，对于Y个子帧中的任意子帧n中，终端需要监测子帧n-100和n-1000。基站或终端发送的gap指示信息中通过gap周期、gap偏移量和gap帧比特图来指示一个gap图样，gap subframe bitmap是一个比特串，值1表示终端被允许使用对应的子帧进行sidelink discovery。那么假设终端每1000ms在sidelink发送一次数据、平均每10s进行一次资源选择，在进行资源选择的时候需要在sidelink上进行接收，指示发送gap时，gap图样中gap subframe bitmap需要1000比特，指示接收gap时，gap图样中gap subframe bitmap需要10000比特，可见开销非常大。
本申请提供的方案旨在减小gap指示过程中的开销。
图1为本申请一实施例提供的终端通信方法流程示意图，如图1所示，该方法包括：
S101、通信设备获取起始信息和长度信息。
其中，起始信息用于指示第一时间资源的起始位置。
第一时间资源可以包含一个或多个子帧。第一时间资源用于指示侧向链路信号的发送或接收时间资源。
S102、通信设备根据起始信息和长度信息确定该第一时间资源。
该通信设备可以是基站，也可以是终端。基站和终端侧的操作相同，都需要根据指示 确定终端在侧向链路进行信号发送或接收的时间资源。
通信设备为终端时，在第一时间资源内，终端可以优先进行侧向链路信号的发送或接收。可选地，终端在第一时间资源内可以不进行上行链路信号的发送或下行链路信号的接收。
通信设备为基站时，基站确定相交互的终端在第一时间资源内优先进行侧向链路信号的发送或接收，那么基站调度终端进行上行链路信号的发送或下行链路信号的接收时，就可以避开第一时间资源。
具体地，通信设备获取了起始信息就可以确定第一时间资源的起始位置，在根据长度信息就可以确定从起始位置开始的几个子帧作为第一时间资源。这样只需要少量的几个比特指示，不需要比特串来一一指示每个子帧。
本实施例中，通信设备获取起始信息和长度信息，并根据起始信息和长度信息确定第一时间资源，进而根据第一时间资源确定侧向链路信号的发送或接收时间资源。实现了用少量比特位就可以确定侧向链路信号的发送或接收时间资源，无需再根据比特串的值一一确定每个子帧属于或不属于第一时间资源，大大节省了开销。
可选地，基站或终端可以通过指示信息指示起始信息。
通信设备接收其他通信设备发送的指示信息。可选地，可以是基站给终端发送指示信息，也可以是终端给终端发送指示信息，还可以是终端给基站发送指示信息。
指示信息中可以包括：偏移信息和长度信息。或者，
指示信息中包括：偏移信息。长度信息采用默认值，即通信设备中预先设置好预设长度信息。其中，预设长度信息可以是预先配置在通信设备中的，也可以是由其他通信设备预先指示的，在此不作限制。
通信设备根据偏移信息确定起始信息。可选地，通信设备根据偏移信息和预设参考信息确定起始信息。预设参考信息可以是预设子帧。起始位置可以是相对于预设子帧偏移的位置。
可选地，第一时间资源中包括至少一组子帧，每组子帧包括至少一个子帧。这种实施方式中，长度信息用于确定每组子帧的数量。
第一时间资源包括多组子帧时，这多组子帧可以按照固定周期进行循环，也可以按照其他规律推算，在此不作限制。
可选地，上述第一时间资源包括：第二时间资源。通信设备根据第二时间资源进行侧向链路信号的接收。
通信设备根据起始信息和长度信息确定该第一时间资源，可以是：通信设备根据起始信息、长度信息以及第一参数，确定第二时间资源。
其中，第一参数可以是终端用于确定监测子帧的参数，监测子帧属于第二时间资源。第一参数可以用k表示，通信设备是终端时，根据k确定监测子帧，其中，终端可以在监测子帧内对资源进行监测，并根据监测结果确定发送数据的资源。k为大于0的整数。
可选地，上述偏移信息可以是相对于预设子帧的偏移值，预设子帧可以是系统帧号(system frame number，SFN)或直连帧号(Direct frame number，DFN)#0的起始，也就是SFN/DFN 0号无线帧中的第一个子帧。相对于预设子帧的偏移值也可以根据终端确定的候选资源确定，例如相对于预设子帧的偏移值可以设置为候选资源所在子帧的起始相对 于预设子帧的偏移，或者，上述第一时间资源中第一组子帧的起始相对于预设子帧的偏移，或者，上述第一时间资源中最后一组子帧的起始相对于预设子帧的偏移，在此不作限制。
在此基础上，一种实施方式中，第二时间资源的每组子帧为[m+offset-P*k，m+offset+duration-1-P*k]。其中，offset为根据偏移信息确定的偏移值，子帧m为偏移值的参考子帧(也就是预设子帧)，(m+offset)为第二时间资源的起始位置，duration为根据长度信息确定的时间长度(每组子帧的子帧个数)，k为第一参数，k为大于或等于1、且小于或等于10的整数，P为大于0的整数。
P为100时，第二时间资源的每组子帧为[m+offset-100*k，m+offset+duration-1-100*k]。假设k被配置为k＝2,3,10，那么第二时间资源包括：子帧[m+offset-200，m+offset+duration-201]、子帧[m+offset-300，m+offset+duration-301]、以及子帧[m+offset-1000，m+offset+duration-1001]。
另一种实施方式中，第二时间资源的每组子帧为[m+offset-P*k’，m+offset+duration-1-P*k’]，offset为根据偏移信息确定的偏移值，子帧m为偏移值的参考子帧(也就是预设子帧)，(m+offset)为第二时间资源的起始位置，duration为根据长度信息确定的时间长度(每组子帧的子帧个数)，k’＝k-k_max，k_max是k取值集合中的最大值，k为第一参数，k为大于或等于1、且小于或等于10的整数，P为大于0的整数。
假设k被配置为k＝2,3,10，k_max＝10，那么k’＝-8,-7,0，也就是第二时间资源包括：子帧[m+offset+800，m+offset+duration+799]、子帧[m+offset+700，m+offset+duration+699]、以及子帧[m+offset，m+offset+duration-1]。
又一种实施方式中，第二时间资源的每组子帧为[m+offset-P*k’，m+offset+duration-1-P*k’]，其中，k’＝k-k_min，k_min是k取值集合中的最小值，k为第一参数，k为大于或等于1、小于或等于10的整数，P为大于0的整数。offset为根据偏移信息确定的偏移值，子帧m为偏移值的参考子帧(也就是预设子帧)，(m+offset)为第二时间资源的起始位置，duration为根据长度信息确定的时间长度(每组子帧的子帧个数)。
假设k被配置为k＝2,3,10，k_min＝2，k’＝0,1,8，也就是第二时间资源包括：子帧[m+offset-800,m+offset+duration-801]、子帧[m+offset-100，m+offset+duration-101]、以及子帧[m+offset’，m+offset+duration-1]。
需要说明的是，子帧m可以是SFN或DFN#0的起始。
子帧(m+offset-P*k)表示与子帧m间隔“offset-P*k-1”个子帧的子帧，若“offset-P*k-1”为正数，则子帧(m+offset-P*k)表示子帧m向后间隔“offset-P*k-1”个子帧的子帧；若“offset-P*k-1”为负数，则子帧(m+offset-P*k)表示子帧m向前间隔“offset-P*k-1”个子帧的子帧。本申请中所有的子帧均以此为参考进行理解，不再赘述。
可选地，duration表示时间长度，可以设为候选资源的子帧数量。
可选地，上述第一时间资源包括：第二时间资源时，通信设备根据起始信息和长度信息确定该第一时间资源，可以是：通信设备根据起始信息、长度信息、第一参数以及第二参数，确定第二时间资源。
第二参数可以表示候选资源所在子帧的数量最小值，第一参数与前述实施例相同，不再赘述。
在此基础上，第二时间资源的每组子帧为[m+offset-P*k,m+ offset+duration+M-1-P*k]，(m+offset)为第二时间资源的起始位置，offset为根据偏移信息确定的偏移值，子帧m为偏移值的参考子帧(也就是预设子帧)，duration为根据长度信息确定的时间长度，k’＝k-k_max，k_max是k取值集合中的最大值，k为第一参数，k为大于或等于1、且小于或等于10的整数，P为大于0的整数。M为第二参数，即候选资源所在子帧的数量最小值，也就是候选资源最少包含M个子帧。
其中，M可以是通信设备预先配置好的默认值，本实施例中，duration与M的和表示第二时间资源每组子帧的数量，duration可以是候选资源的子帧数量相对于M的增量。
假设k被配置为k＝2,3,10，k_min＝2，k’＝0,1,8，也就是第二时间资源包括：子帧[m+offset-200,m+offset+duration+M-201]、子帧[m+offset-300,m+offset+duration+M-301]、以及子帧[m+offset-1000,m+offset+duration+M-1001]。
可选地，如果指示信息中只包含偏移信息，并使用预设长度信息，第二时间资源的每组子帧可以为[m+offset-P*k,m+offset+M-1-P*k]。其中参数参照前述实施例，在此不再赘述。
进一步地，上述第一时间资源中的子帧可以按照周期信息确定，通信设备可以获取周期信息。
可选地，周期信息也携带在指示信息中。即指示信息中包括：偏移信息、长度信息以及周期信息。或者，指示信息中包括：偏移信息和周期信息，长度信息采用预设长度信息。
可选地，指示信息中包括：偏移信息。周期信息和长度信息都采用预设的默认值。
第一时间资源包括第三时间资源时，通信设备根据起始信息和长度信息确定该第一时间资源，可以是：通信设备根据起始信息、长度信息、以及周期信息，确定第三时间资源。
周期信息可以指示第三时间资源中一组子帧的重复周期。
可选地，第三时间资源的子帧为[m+offset，m+offset+duration-1]，并以period为周期重复，即第三时间资源还包含子帧[m+offset+period，m+offset+duration-1+period]，[m+offset+2*period，m+offset+duration-1+2*period]等，其中，offset为根据偏移信息确定的偏移值，子帧m为偏移值的参考子帧(也就是预设子帧)，(m+offset)为第二时间资源的起始位置，duration为根据长度信息确定的时间长度，period为根据周期信息确定的重复周期。
或者，第三时间资源的子帧为[m+offset，m+offset+duration-1]，并以period*P为周期重复，即第三时间资源还包含子帧[m+offset+period*P，m+offset+duration-1+period*P]，[m+offset+2*period*P，m+offset+duration-1+2*period*P]等，其中，P为大于1的整数。
重复周期可以设置为终端发送数据使用的资源预留间隔，若period指示第三时间资源中每组子帧的重复周期，则period可以设置为终端发送数据使用的资源预留间隔；若period*P指示第三时间资源中每组子帧的重复周期，则period可以设置为与终端在侧向链路控制信息(Sidelink Control Information，SCI)中指示资源预留(resource reservation)域相等的值。
举例说明，第三时间资源的子帧为[m+offset，m+offset+duration-1]，并以period为周期重复，即第三时间资源还包含子帧[m+offset+period，m+offset+duration-1+period]，[m+offset+2*period，m+offset+duration-1+2*period]时，假设m＝0，offset＝8000，duration＝10，period＝1000，第三时间资源的子帧索引可以表示为[8000,8009],[9000, 9009],[10000,10009]。如果在LTE系统中，每10个子帧为1个帧。因此，索引为8000的子帧是SFN/DFN#800中的子帧0，索引为8001的子帧是SFN/DFN#800中的子帧1，以此类推，不再赘述。
如果终端被允许只使用一种资源预留间隔，那么指示信息中可以不包含周期信息，而使用默认值，例如预先配置重复周期的默认值为1000。这样，可以确定第三时间资源包括：子帧[m+offset,m+offset+duration-1]，并以1000为周期重复，比如包含子帧[m+offset+1000,m+offset+duration+999]。
进一步地，通信设备还可以获取资源池信息。资源池信息也可以携带在上述指示信息中，在此不做限制。需要说明的是，由于根据指示信息确定终端被允许使用用于V2X业务的子帧(第三时间资源的子帧)时使用的是对可能属于资源池的子帧进行编号的索引，而不同资源池可能属于资源池的子帧集合不同，也就是集合(t_0,t_1,t_2,…,t_i,…,t_max)不同，因此，还需要指示资源池，具体可以是指示发送TB的资源池。当然，也可以不在指示信息中指示资源池，而是预先在通信设备中配置好资源池的默认值，即使用默认的资源池。
通信设备如果是终端，资源池信息用于指示终端在侧向链路发送或接收信号所使用的资源池。通信设备如果是基站，资源池信息用于指示与该基站相交互的终端在侧向链路发送或接收信号所使用的资源池。
需要说明的是，在V2X中，不是所有子帧都是可能属于用于资源池。比如，在LTE系统中，一个SFN/DFN周期内的子帧总数为10240，可能属于资源池的子帧为(t_0,t_1,t_2,…,t_i,…,t_max)，其中0<＝t_i<10240，t_i是相对于SFN/DFN#0中的子帧#0的子帧索引，即第一索引，按子帧索引的递增顺序排列。如果i是只将可能属于用于V2X资源池的这组子帧进行编号的索引，称为第二索引，例如，(t_0,t_1,t_2,…,t_i,…,t_max)为(0,1,2,5,6,7,9,…)。
上述第三时间资源中确定的子帧所用的索引可以是第一索引，也可以是第二索引。
如果确定上述第三时间资源的子帧所用的索引为第二索引，那么，可选地，通信设备根据起始信息、长度信息、以及周期信息，确定第三时间资源，可以是：确定第三时间资源的子帧为[t_(m+offset),t_(m+offset+duration-1)]，并以period或period乘以某一值P为周期重复，比如子帧[t_(m+offset+period*P),t_(m+offset+duration-1+period*P)]等，其中，offset为根据偏移信息确定的偏移值，子帧t_m是offset的参考子帧，(t_m+offset)为第三时间资源的起始位置，也可以说，offset是相对于子帧t_m的偏移。若m＝0，offset是相对于子帧t_0的偏移。
如果offset和duration使用的索引是第一索引，period使用的索引是第二索引，可选地，通信设备根据起始信息、长度信息、以及周期信息，确定第三时间资源，可以是：第三时间资源的子帧为[m+offset，m+offset+duration-1]，并以period或period乘以某一值P为周期重复，比如包括子帧[n,n+’duration’-1],[b,b+’duration’-1]等，其中，t_a＝m+offset，n＝t_(a+period*P),b＝t_(a+period*P*2)。若子帧m是SFN/DFN#0的起始，则m＝0。
进一步地，指示信息中还可以包括：第一时间资源重复的次数(repetition)。可选地，可以将第一时间资源重复的次数设为终端的资源重选计数器的值。具体地，第一时间资源包括第二时间资源时，指示第二时间资源重复的次数；第一时间资源包括第三时间资源时， 指示第三时间资源重复的次数。
比如，当第三时间资源重复的次数为3时，指示的第三时间资源中包含子帧[m+offset,m+offset+duration-1]、子帧[m+offset+period*P,m+offset+duration-1+period*P]、以及子帧[m+offset+period*P*2，m+offset+duration-1+period*P*2]。
上述实施例中duration所使用的比特数可以不超过7，period所使用的比特数可以不超过4，资源池所使用的比特数可以不超过3，重复的次数(repetition)所使用的比特数可以不超过4，可见大大减少了指示开销。
可选地，通信设备还可以同时指示第二时间资源和第三时间资源，相应地，接收到指示信息的通信设备也可以同时确定第二时间资源和第三时间资源。
具体实现时，可以在指示信息中包括：偏移信息、长度信息以及周期信息。或者，指示信息中包括：偏移信息和周期信息，长度信息采用预设长度信息。或者，指示信息中包括：偏移信息，周期信息和长度信息使用预设的默认值。在此不做限制。
接收到指示信息的通信设备可以采用前述实施例中的方式确定第二时间资源和第三时间资源。例如，确定第二时间资源包括子帧[m+offset-P*k,m+offset+duration-1-P*k]；确定第三时间资源为子帧[m+offset,m+offset+duration-1]，并以period或period乘以某一值P为周期重复，如包括子帧[m+offset+period*P,m+offset+duration-1+period*P]、[m+offset+period*2*P,m+offset+duration-1+period*2*P]等。
或者，确定第二时间资源包括子帧[m+offset-P*k,m+offset+duration-1-P*k]；确定第三时间资源为子帧[m+offset,m+offset+duration-1]，并以period或period乘以某一值P为周期在第二索引(period使用第二索引)上重复，如包括子帧[n,n+duration-1],[b,b+duration-1]等，其中，t_a＝m+offset，n＝t_(a+period*P),b＝t_(a+period*P*2)。在此不再赘述。
可选地，如果通信设备支持短资源预留间隔，即资源预留间隔小于预设时间阈值，比如，该预设时间阈值等于P。这种情况下，对于第一时间资源包括：第二时间资源的实施方式有一定增强。
第二时间资源包括至少一组子帧，长度信息duration表示每组子帧包含的子帧数量。通信设备根据偏移信息、长度信息以及第一参数，确定第二时间资源时：
一种实现方式中，第二时间资源包括子帧[m+offset-P*k，m+offset+duration-1-P*k]。例如，第二时间资源包括子帧[m+offset-100，m+offset+duration-101]，k的取值可以不包含1。
如果引入第二参数M，第二时间资源包括[m+offset-P*k，m+offset+duration+M-1-P*k]。
或者，另一种实现方式中，第二时间资源包括子帧[m+offset-P*k，m+offset+a’-1-P*k]。a’＝min(duration,k_max*P)，0<k<1。k_max是k取值集合中的最大值。
如果引入第二参数M，a’＝min(duration+M,k_max*P)。
或者，再一种实现方式中，指示信息中包括两个偏移信息，分别记为offset和offset2，offset和offset2可以相同也可以不同，第二时间资源可以包括子帧[m+offset2,m+offset2+a’-1]，其中，a’＝min(duration,k_max*P)，0<k<1。k_max是k取值集合中的最大值。offset2也是相对于子帧m的偏移值，或者offset2是相对于子帧(m+offset)的偏移值。
如果引入第二参数M，a’＝min(duration+M,k_max*P)。
可选地，第二偏移信息offset2也可以预先配置在通信设备内，在此不作限制。
或者，又一种实施方式中，指示信息中可以包括多个偏移信息，即除了offset外，还可以包括一个或多个offset_i，offset_i也都是相对于预设子帧(子帧m)的偏移值，或者是相对于子帧(m+offset)的偏移值。
第二时间资源可以包括子帧[m+offset_i，m+offset_i+duration_i-1]，其中，duration_i＝min(duration，k_i*P)，k_i是小于1的k的某一个取值，即duration_i表示第二时间资源中的一段时间资源长度。
如果引入第二参数M，duration_i＝min(duration+M，k_i*P)。
图2为本申请另一实施例提供的终端通信方法流程示意图，如图2所示，该方法包括：
S201、通信设备获取起始信息和子帧间隔信息。该起始信息用于指示第一时间资源的起始位置，该子帧间隔信息用于指示第一时间资源中相邻两个子帧之间的间隔。
本实施例中，子帧可以连续或不连续，根据起始信息确定了起始子帧后，通过子帧间隔信息依次推导，可以得出第一时间资源包含的所有子帧。
S202、通信设备根据起始信息和子帧间隔信息确定第一时间资源。
第一时间资源可以包含一个或多个子帧。第一时间资源用于指示侧向链路信号的发送时间资源。
本实施例中的第一时间资源与前述实施例中第三时间资源类似，都用于侧向链路信号的发送。即后续基于图2的方法实施例中，第一时间资源都指代侧向链路信号的发送时间资源。
通信设备为终端时，在第一时间资源内，终端可以优先进行侧向链路信号的发送。可选地，终端在第一时间资源内可以不进行上行链路信号的发送或下行链路信号的接收。
通信设备为基站时，基站确定相交互的终端在第一时间资源内优先进行侧向链路信号的发送，那么基站调度终端进行上行链路信号的发送或下行链路信号的接收时，就可以避开第一时间资源。
本实施例中，通信设备获取起始信息和子帧间隔信息，根据起始信息和子帧间隔信息确定第一时间资源，进而根据第一时间资源确定侧向链路信号的发送时间资源。实现了用少量比特位就可以确定侧向链路信号的发送时间资源，无需再根据比特串的值一一确定每个子帧属于或不属于第一第一时间资源，大大节省了开销。
可选地，与前述实施例类似，可以通过指示信息指示起始信息和子帧间隔信息。即通信设备接收其他通信设备发送的指示信息，该指示信息中包括：偏移信息和子帧间隔信息。或者，指示信息中包括：偏移信息。子帧间隔信息采用预设子帧间隔信息，即预先设置个默认值。
通信设备根据偏移信息确定起始信息。
可选地，通信设备根据偏移信息和预设参考信息确定起始信息。预设参考信息可以是预设子帧。起始位置可以是相对于预设子帧偏移的位置。
具体地，偏移信息可以是第一时间资源中第一个子帧相对于预设子帧的偏移，其中，预设子帧可以是SFN/DFN#0的起始，也就是SFN/DFN#0中的子帧0。偏移信息可以设置成传输一个TB时第一个发送子帧相对于预设子帧的偏移，或者是传输一个TB时第二 个发送子帧相对于预设子帧的偏移。但不以此为限。
可选地，通信设备根据起始信息和子帧间隔信息确定的第一时间资源可以表示为：子帧(m+offset)和子帧(m+offset+retransmission offset)。其中，offset为根据偏移信息确定的偏移值，子帧m为偏移值的参考子帧(也就是预设子帧)，retransmission offset为根据子帧间隔信息确定的子帧间隔。(m+offset)为第一时间资源的起始位置。
可以理解为第一时间资源包括子帧(m+offset)、以及子帧(m+offset)向后间隔“retransmission offset”个子帧的子帧。
进一步地，通信设备可以获取周期信息。该周期信息可以用于指示第一时间资源中每组子帧的重复周期。
可选地，通信设备根据起始信息和子帧间隔信息确定第一时间资源，可以是：通信设备根据起始信息、子帧间隔信息以及周期信息，确定第一时间资源。
可选地，第一时间资源中第一个周期包括子帧(m+offset)和子帧(m+offset+retransmission offset)，并以period或period乘以某一值P为周期重复，比如包括：子帧(m+offset+period*P)、子帧(m+offset+retransmission offset+period*P)、子帧(m+offset+2*period*P)、子帧(m+offset+retransmission offset+2*period*P)等，在此不作限制。
其中，若子帧m是SFN/DFN#0的起始，则m＝0。当子帧m是SFN/DFN#0的起始，且offset的值设置成传输一个TB时第一个发送子帧相对于预设子帧的偏移，retransmission offset的值设置成传输一个TB时第二个发送子帧相对于第一个发送子帧的偏移，period设置成与终端在SCI中指示的资源预留(resource reservation)域相等的值。
举例说明，m＝0，offset＝8000,retransmission offset＝3,period＝1000。上述第一时间资源包括：子帧8000，子帧8003，子帧9000，子帧9003，子帧10000，10003等。假设在LTE系统中，每10个子帧为1个帧，那么子帧8000是SFN/DFN#800中的子帧0，子帧8003是SFN/DFN#800中的子帧3，以此类推。
如果终端被允许只使用一种资源预留间隔，那么指示信息中可以不包含周期信息，而采用预设周期信息。例如，如果终端的预设周期信息是1000，终端或基站根据offset和retransmission offset确定上述第一时间资源的子帧包括：第一个周期中子帧(m+offset)和子帧(m+offset+retransmission offset)，并以1000为周期重复，比如包括：子帧(m+offset+1000)、子帧(m+offset+retransmission offset+1000)、子帧(m+offset+2000)、子帧(m+offset+retransmission offset+2000)等。
进一步地，与前述实施例类似，通信设备还可以获取资源池信息。
资源池信息也可以携带在上述指示信息中，在此不做限制。需要说明的是，由于根据指示信息确定终端被允许使用用于V2X业务的子帧(第一时间资源的子帧)时使用的是对可能属于资源池的子帧进行编号的索引，而不同资源池可能属于资源池的子帧集合不同，也就是集合(t_0,t_1,t_2,…,t_i,…,t_max)不同，因此，还需要指示资源池，具体可以是指示发送TB的资源池。当然，也可以不在指示信息中指示资源池，而是预先在通信设备中配置好资源池的默认值，即使用默认的资源池。
通信设备如果是终端，资源池信息用于指示终端在侧向链路发送或接收信号所使用的资源池。通信设备如果是基站，资源池信息用于指示与该基站相交互的终端在侧向链路发送或接收信号所使用的资源池。
需要说明的是，在V2X中，不是所有子帧都是可能属于用于资源池。比如，在LTE系统中，一个SFN/DFN周期内的子帧总数为10240，可能属于资源池的子帧为(t_0,t_1,t_2,…,t_i,…,t_max)，其中0<＝t_i<10240，t_i是相对于SFN/DFN#0中的子帧#0的子帧索引，即第一索引，按子帧索引的递增顺序排列。如果i是只将可能属于用于V2X资源池的这组子帧进行编号的索引，称为第二索引，例如，(t_0,t_1,t_2,…,t_i,…,t_max)为(0,1,2,5,6,7,9,…)。
确定上述第一时间资源时，如果offset、retransmission offset和period均使用第二索引，则第一时间资源的第一个周期包括子帧t_(m+offset)和子帧t_(m+offset+retransmission offset)，并以period或period乘以某一值P为周期重复，比如子帧t_(m+offset+period)、子帧t_(m+offset+retransmission offset+period)、子帧t_(m+offset+2*period)、子帧t_(m+offset+retransmission offset+2*period)等，其中，子帧t_m是offset的参考子帧，也就是说，offset是相对于子帧t_m的偏移。若m＝0，offset是相对于子帧t_0的偏移。
可选地，如果确定上述第一时间资源时，offset使用的索引是第一索引，retransmission offset和period使用的索引是第二索引。则第一时间资源的第一个周期包括：子帧t_n(其中t_n＝m+offset)和子帧t_(n+retransmission offset)，并以period或period乘以某一值P为周期重复，比如包括子帧t_(n+period)、子帧t_(n+retransmission offset+period)、子帧t_(n+2*period)、子帧t_(n+retransmission offset+2*period)等，其中，子帧m是offset的参考子帧，也就是说，offset是相对于子帧m的偏移。若子帧m是SFN/DFN#0的起始，则m＝0。
进一步地，指示信息中还可以包括：第一时间资源重复的次数(repetition)。可以设置第一时间资源重复的次数为终端的资源重选计数器的值。比如，当第一时间资源重复的次数为3时，第一时间资源重复3次，第一时间资源的子帧包括：子帧(m+offset)、(m+offset+retransmission offset)、(m+offset+period*P)、(m+offset+retransmission offset+period*P)、(m+offset+period*P*2)、(m+offset+retransmission offset+period*P*2)。
可选地，通信设备还可以获取第一时间资源和第二时间资源的相对偏移值。
指示信息还可以包括：第一时间资源和第二时间资源的相对偏移值，这里的第二时间资源与前述实施例的第二时间资源相同，即通信设备根据第二时间资源进行侧向链路信号的接收。
通信设备根据起始信息和子帧间隔信息确定第一时间资源，包括：通信设备根据起始信息、子帧间隔信息、第一时间资源和第二时间资源的相对偏移值，确定第一时间资源。
可选地，第一时间资源和第二时间资源的相对偏移值可以由指示信息携带。
这里的指示信息为指示第一时间资源的指示信息，该指示信息可以包括：偏移信息、子帧间隔信息、第一时间资源和第二时间资源的相对偏移值。或者，指示信息可以包括：偏移信息、第一时间资源和第二时间资源的相对偏移值。子帧间隔信息使用预设子帧间隔信息。
具体地，通信设备还可以获取到指示第二时间资源的指示信息，指示第二时间资源的指示信息可以参照图1所示的实施例，在此不再赘述，具体可以包括第二时间资源的偏移信息、时长信息等。该偏移信息可以是第二时间资源的偏移值。
或者，通信设备接收其他通信设备发送的指示信息中同时指示第一时间资源和第二时 间资源，该指示信息包括：偏移信息、子帧间隔信息、第一时间资源和第二时间资源的相对偏移值、长度信息。其中偏移信息指示第一时间资源的起始位置，也指示第二时间资源的起始位置。
可选地，第一时间资源中的每组子帧根据周期信息重复的话，第一时间资源和第二时间资源的相对偏移值可以指示第一时间资源中第一个周期中第一个发送子帧相对于第二时间资源的偏移值的偏移，或者是第一时间资源中第一个周期中第二个发送子帧相对于第二时间资源的偏移值的偏移。
具体地，通信设备可以按照前述实施例提供的方法先确定第二时间资源包括：子帧[m+offset-P*k,m+offset+duration-1-P*k]，其中参数参照前述实施例的解释。进而确定第一时间资源包括：子帧(m+offset+offset_tx)、(m+offset+offset_tx+retransmission offset)，并以period或period乘以某一值P为周期重复，如包括子帧(m+offset+offset_tx+period*P)、子帧(m+offset+offset_tx+retransmission offset+period*P)、子帧(m+offset+offset_tx+2*period*P)、子帧(m+offset+offset_tx+retransmission offset+2*period*P)等，其中，offset_tx表示第一时间资源和第二时间资源的相对偏移值。
另一实施方式中，基于指示信息包括上述资源池信息的情况，retransmission offset和period均使用上述第二索引。通信设备可以按照前述实施例提供的方法先确定第二时间资源包括：子帧[m+offset-P*k,m+offset+duration-1-P*k]。进而确定第一时间资源包括：子帧t_n、子帧t_(n+retransmission offset)，并以period或period乘以某一值P为周期在第二索引上重复，如包括：子帧t_(n+period*P)、子帧t_(n+retransmission offset+period*P)、子帧t_(n+period*P*2)、子帧t_(n+retransmission offset+period*P*2)等，其中，t_n＝m+offset+offset_tx。
图3为本申请提供的终端通信方法中一种时间资源示意图。如图3所示，通信设备根据起始信息、子帧间隔信息、第一时间资源和第二时间资源的相对偏移值，确定第一时间资源。
进一步地，通信设备根据起始信息和长度信息确定该第二时间资源，可以是：通信设备根据起始信息、长度信息、以及第一时间资源和第二时间资源的相对偏移值，确定该第二时间资源。
可选地，通信设备确定第二时间资源的子帧包括：子帧[m+offset-offset_rx-100*k,m+offset-offset_rx+duration-1-100*k]，其中，offset_rx表示第一时间资源和第二时间资源的相对偏移值，offset_rx可以设为第二时间资源中第一个周期中第一个发送子帧相对于第二时间资源的偏移值的偏移，或者是第二时间资源中第一个周期中第二个发送子帧相对于第二时间资源的偏移值的偏移。
进而确定第一时间资源包括：子帧(m+offset)、子帧(m+offset+retransmission offset)，并以period或period乘以某一值P为周期重复，如包括：子帧(m+offset+period*P)、子帧(m+offset+retransmission offset+period*P)、子帧(m+offset+period*P*2)、子帧(m+offset+retransmission offset+period*P*2)等。
或者，另一实施方式中，基于通信设备获取资源池信息，retransmission offset和period使用的是第二索引。通信设备确定第二时间资源的子帧包括：[m+offset-offset_rx-100*k,m+offset-offset_rx+duration-1-100*k]。进而确定第一时间资源包 括：子帧t_n、子帧t_(n+retransmission offset)，并以period或period乘以某一值P为周期在第二索引上重复，如包括：子帧t_(n+period*P)、子帧t_(n+retransmission offset+period*P)、子帧t_(n+period*P*2)、子帧t_(n+retransmission offset+period*P*2)等，其中，t_n＝m+offset。
上述实施例中duration所使用的比特数可以不超过7，retransmission offset所使用的比特数可以不超过4，period所使用的比特数可以不超过4，资源池所使用的比特数可以不超过3，重复的次数(repetition)所使用的比特数可以不超过4，可见大大减少了指示开销。
