Description

一种终端通信的方法及相关设备
本申请要求于2016年12月14日提交中国专利局、申请号为201611155230.0、发明名称为“一种SL传输冲突解决的方法”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
本申请涉及电学领域,尤其涉及一种终端通信的方法及相关设备。
背景技术
第三代合作伙伴项目(the 3rd Generation Partnership Project,3GPP)的车联网(Long Term Evolution Vihicle to Everything,LTE-V2X)技术可以与专用短程通信(Dedicated Short Range Communication,DSRC)技术共用5.9GHz频段作为工作频率。为了避免终端密度较高时发送的消息数量过多而导致的信道拥塞问题,欧洲电信标准协会为DSRC终端在5.9GHz频段上的发送行为定义了一些约束条件以限制终端占用信道的时间和比例,其中包括限制两次相邻传输之间的最小时间间隔,如图1.a所示,两次相邻传输之间的时间间隔为Toff,定义两次相邻传输之间的最小时间间隔为Toff-min,即约束条件为Toff≥Toff-min
车联网V2X车与车(Vehicle to Vehicle,V2V)通信、人与车(Pedestrian to Vehicle,P2V)通信、车与人(Vehicle to Pedestrian,V2P)通信和车与技术设施(Vehicle to Infrastructure,V2I)通信,其中V2I通信也可以称为车与网络(Vehicle to Network,V2N)通信。车联网的终端(User Equipment,UE)可以是车载终端或手持终端。UE可能发送旁路同步信号(Sidelink Synchronization Signal,SLSS)、调度指示(Scheduling Assignment,SA)与数据(Data)。严格来说,SLSS只包含旁路主同步信号(Primary Sidelink Synchronization Signal,PSSS)和旁路辅同步信号(Secondary Sidelink Synchronization Signal,SSSS)。因PSSS和SSSS与旁路物理广播信道(Physical Sidelink Broadcast channel,PSBCH)的广播消息在同一个子帧中一起传输,如无特别说明:PSSS和SSSS统一用SLSS表示;当终端发送SLSS时,隐含了终端也会在满足现行标准定义的条件下在同一子帧的PSBCH信道上发送广播消息。另外,调度指示也称为旁路控制信息(Sidelink Control Information,SCI),本申请中将调度指示与Data统称为V2X消息,目前同一个传输块(Transport Block,TB)的一次SA传输与对应的Data传输在相同子帧内传输。SLSS或V2X消息的传输由于周期不同、传输时刻偏移不同等情况,可能存在两次相邻传输之间违背约束条件Toff≥Toff-min的情况。在LTE-V2X中,SLSS的传输周期固定为160ms,而V2X消息的传输周期可以为{20ms,50ms,n*100ms},n=1,2...10。因此,如图1.b所示,当UE需要发送SLSS和SA&Data,且V2X消息的传输周期为100ms时,传输过程中,有一些传输之间的间隔Toff会小于Toff-min,从而破坏了Toff-min的约束。
有鉴于此,现有技术中提出的解决方案是在传输过程中,设定SA/Data传输的优先级高于SLSS传输的优先级,在Toff-min约束被破坏的情况发生时,丢弃SLSS的传输。
然而,对于网络覆盖范围外(Out of Coverage,OoC)的接收终端来说,SLSS用于确保车联网的终端之间保持同步,是非常重要的信号。发送终端在Toff-min约束被破坏时丢弃SLSS可能影响接收端的同步性能。此外,现有技术中在Toff-min约束被破坏的情况发生时, 直接丢弃SLSS的传输,解决方式过于单一。

具体实施方式
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,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、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本申请实施例可应用于如图2.a和图2.b所示的系统架构,图2.a所示为网络覆盖范围内的场景,基站eNB1向UE1和UE2发送广播消息,该广播消息包含于SIB21中,SIB21包含V2X通信过程中的一些配置参数,比如资源配置等,发送终端UE1向接收终端UE2发送V2X消息或者SLSS,其中V2X消息包括SA&Data;图2.b所示为网络覆盖范围外的场景,即发送终端UE1和接收终端UE2不在基站的覆盖范围内,发送终端UE1向接收终端UE2发送SA&Data或者SLSS,但接收不到基站发送的广播消息等,在该场景下,部分参数的配置可以采用预先配置的方式,例如预配置的偏移量等。
下面对本申请实施例的流程进行描述,请参阅图3,本申请实施例中终端通信的方法一个实施例包括:
301、发送终端确定处理的方式;
当待发送的非连续时间间隔上的两个相邻的信号之间的发送间隔小于第一预设值时,发送终端确定两个相邻信号的处理的方式。其中,两个相邻的信号可以是第一信号、可能的第二信号和第三信号中的任意两个信号,且第二信号为第一信号的重传信号,第一信号携带有控制信息和数据信息,第三信号为传输周期固定的信号。本申请实施例中,处理的方式包括以下至少一种或多种可选处理的方式:调整第一信号的传输时刻、调整第二信号的传输时刻、调整第三信号的传输时刻、丢弃第二信号或丢弃第二信号并调整第一信号的MCS值。
其中,处理的方式的确定可由基站通过广播消息通知给发送终端,或者发送终端采用预配置的规则,具体此处不做限定。
302、发送终端根据处理的方式对两个相邻的信号中的至少一个信号进行处理。
发送终端确定了处理的方式之后,当待发送的两个相邻的信号为第一信号和第三信号时,发送终端根据确定的处理的方式调整该两个相邻的信号中的至少一个信号的传输时刻;当待发送的两个相邻的信号中包括第二信号时,发送终端根据确定的处理的方式调整,处理的方式包括以下至少一种可选的处理的方式:调整该两个相邻的信号中的至少一个信号的传输时刻、丢弃第二信号或者丢弃第二信号并调整第一信号的MCS值。
发送终端调整两个相邻的信号中的至少一个信号的发送时刻,使得非连续时间间隔上的两个相邻的信号的发送间隔大于第一预设值;或,使得非连续时间间隔上的两个相邻的信号调整在时间上连续的两个时间间隔上。
本申请实施例中,时间间隔可以理解为子帧。当待发送的非连续时间间隔上的两个相邻的信号之间的发送间隔小于第一预设值时,发送终端根据确定的调整方式调整发生传输冲突的两个相邻的信号中的至少一个信号,且调整方式包括调整信号的传输时刻,相比于现有技术中的丢弃第三信号,本申请实施例在存在传输冲突时调整信号的传输时刻,保证了接收终端同步的性能。
为便于理解,下面对本申请实施例的具体流程进行描述,请参阅图4,本申请实施例中终端通信的方法另一实施例包括:
401、发送终端确定冲突情况;
发送终端在传输信号时会预留多次信号传输的资源,因此发送终端能预先根据待发送的非连续时间间隔上的任意两个相邻的信号之间的发送间隔确定是否存在传输冲突,其中本申请实施例中,时间间隔可以理解为子帧,当发送终端确定非连续时间间隔上的两个相邻的信号间的发送间隔小于第一预设值时,即该两个相邻的信号之间存在传输冲突,进一步地,为解决该传输冲突,发送终端需先确定该发送间隔小于第一预设值的两个相邻的信号之间的冲突情况,其中冲突情况可以包括以下至少一种:发生传输冲突的两个信号的位置、两个信号的类型、传输时延要求、当前信道的拥塞等级或可用资源等,具体此处不做限定。为便于理解,本申请实施例中,以冲突情况包括发生传输冲突的两个信号的类型和当前信道的拥塞等级为例进行说明。
本申请实施例中,发送终端发送的信号至少包括第一信号、可能的第二信号或第三信号,其中第二信号为第一信号的重传信号,第一信号和第二信号均携带有控制信息和数据信息,第三信号为传输周期固定的信号,如在车联网通信中,第一信号可为SA&Data,第二信号为SA&Data的重传信号,第三信号为SLSS。发送终端可分为传输第三信号的终端和没有传输第三信号的终端,当发送终端为传输第三信号的终端时,发生冲突的场景如图5.a所示,其中第一信号以白色长方块表示,第二信号以黑色长方块表示,第三信号以短方块表示,冲突场景包括:第一信号与第三信号发生传输冲突、第二信号与第三信号发生传输冲突,第一信号、第二信号与第三信号都发生传输冲突;若发送终端为不传输第三信号的终端,发生冲突的场景如图5.b所示,当第一信号和第二信号在逻辑资源池连续时间间 隔即连续子帧上,在物理资源池被其他终端发送的第三信号分隔开,导致相邻的第一信号与第二信号之间的发送间隔小于第一预设值,或者,目前由于第一信号和第二信号之间的发送间隔在0~15个子帧中随机选择,即第一信号和第二信号之间的发送间隔Toff在0~15ms之间,且该发送间隔Toff<Toff-min
402、发送终端获得当前信道的拥塞等级;
在实际应用中,拥塞程度可通过信道繁忙比例(Channel busy ratio,CBR)表示。CBR是指在一定时间间隔内,信道因为成功传输数据或者碰撞引起的忙碌状态时间与总时间的比值,可对网络拥塞提供早期的预警。CBR可定义为接收信号强度指示(Sidelink-Received Signal Strength Indication,S-RSSI)在一定的观察时间内超过预配置或网络配置的门限的子信道的比例。该子信道的比例与拥塞程度正相关,即该子信道的比例越高,拥塞程度也越高,该子信道的比例越低,拥塞程度也越低。
发送终端通过比较当前信道的CBR是否大于第二预设值来确定当前信道的拥塞等级,该当前信道为物理旁路共享信道(Physical Sidelink Shared Channel,PSSCH),其中拥塞等级可以根据拥塞程度的不同至少分为第一拥塞等级和第二拥塞等级,第一拥塞等级用来表示信道的CBR小于第二预设值,第二拥塞等级用来表示信道的CBR大于第二预设值。
可选的,在实际应用中,拥塞等级可包括多个等级,例如,信道的拥塞等级分为三个等级,分别用于表示信道的CBR小于第三预设值、信道的CBR大于第三预设值小于第四预设值和信道的CBR大于第四预设值,因此信道的拥塞等级的个数具体此处不做限定。
拥塞等级获得可由发送终端通过测量得到,或者发送终端从基站的广播消息中获得。
403、发送终端将两个相邻的信号的类型与当前信道的拥塞等级关联得到冲突情况;
发送终端确定了存在冲突情况并获得当前信道的拥塞等级后,将发生传输冲突的两个相邻的信号的类型与当前信道的拥塞等级关联结合以得到冲突情况。例如该两个相邻的信号的类型为第一信号和第二信号,当前信道的拥塞等级为第一拥塞等级,冲突情况为第一信号和第二信号间发生传输冲突且拥塞等级为第一拥塞等级。
404、发送终端获得冲突情况与处理的方式的对应关系;
发送终端接收基站的广播信息,其中该广播信息中携带冲突情况与处理的方式的对应关系。
需要说明的是,发送终端获得该对应关系的方式有多种,例如发送终端在预配置或预存储的信息中获得该对应关系,故发送终端获得冲突情况与处理的方式的对应关系的方式具体此处不做限定。
本申请实施例中,处理的方式至少包括以下可选的处理的方式中的一种或多种:调整第一信号的传输时刻、调整第二信号的传输时刻、调整第三信号的传输时刻或丢弃第二信号。其中,调整信号的传输时刻包括提前或者延迟信号的传输时刻。
可以理解的是,实际应用中,在调整信号的传输时刻时需要满足一定的要求,如满足时延的要求,即从产生信号到发出信号的时间间隔不超过预定数值,且信号的传输时刻的调整值可以由发送终端配置或者基站配置,配置方式可以为满足当前标准定义的Toff-min要求和时延要求的最小偏移值或者在该最小偏移值的基础上增加一个随机偏移值以减少传输 冲突,其中随机偏移值为预置偏移范围内的一个随机值,故调整值的配置方式具体此处不做限定。
可选的,当发生传输冲突的相邻的两个信号其中之一为第二信号时,且处理的方式包括丢弃第二信号,则发送终端调整第一信号携带的数据信息的MCS值,调整该MCS值的方式包括降低MCS值或提高MCS值,其中降低MCS值能提高第一信号的鲁棒性,鲁棒性即抗变换性,指控制系统在一定结构、大小等参数的摄动下,维持某些性能的特性;而提高MCS值可以减少资源的占用,降低拥塞程度。在实际应用中,可以由基站决定或者根据预先配置的条件来决定如何调整MCS值,其中确定如何调整MCS值的方式有多种,例如,判断消息或业务的优先级,对高优先级的消息或业务即采用降低MCS值的方式,对低优先级的消息或业务采用提高MCS值的方式;或确定当前信道的CBR,若当前信道的CBR小于预设值,则采用降低MCS值的方式,若当前信道的CBR大于预设值,则采用提高MCS值的方式;还可以固定采用降低MCS值的方式或提高MCS值的方式,故确定调整MCS值的方式具体此处不做限定。
可以理解的是,为了保证不同的终端在相同的冲突情况下的处理的方式一致,各冲突情况对应一种处理的方式,冲突情况与处理的方式的对应关系可以如表一所示,
表1
Figure PCTCN2017072756-appb-000001
可选的,冲突情况与处理的方式的对应关系可以以表格、灵活的文档格式或K-V格式等方式存储,具体此处不做限定。
需要说明的是,实际应用中,冲突情况与处理的方式的对应关系可以由运营商根据实际情况定义,例如冲突场景为第一信号与第二信号发生传输冲突且为第一拥塞等级,对应的调整方式为丢弃第二信号,故冲突情况与处理的方式的对应关系具体此处不做限定。
需要注意的是,本实施例中,发送终端通过步骤401以及步骤403即可得到冲突情况,通过步骤404即可获取到冲突情况与处理的方式的对应关系,而这两个过程之间并不存在步骤的先后顺序,可以先执行步骤401以及403,也可以先执行步骤404,或者同时执行,具体此处不做限定
405、发送终端根据冲突情况与处理的方式的对应关系确定与冲突情况对应的处理的方式;
发送终端获得冲突情况与处理的方式的对应关系后,在该对应关系中找出与发送终端得到的冲突情况对应的处理的方式,使得发送终端通过该处理的方式对发生传输冲突的两个相邻的信号中的至少一个信号进行处理。
406、发送终端根据处理的方式对两个相邻的信号中的至少一个信号进行处理;
发送终端确定与冲突情况对应的处理的方式后,通过该处理的方式对两个相邻的信号中的至少一个信号进行调整,使得该非连续时间间隔上的两个相邻的信号间的发送间隔大于第一预设值,或者将该两个相邻的信号进行聚合,使该两个相邻的信号在时间上连续的两个时间间隔上。例如,如图6.a所示,其中第一信号以白色长方块表示,第二信号以黑色长方块表示,第三信号以短方块表示,各方块上的箭头表示信号的传输时刻可调整的方向,在图7所示的冲突场景1中,第一信号与第三信号的发送间隔Toff<Toff-min,即第一信号与第三信号发生传输冲突,调整方式包括以下方式:
1-1、调整第一信号的传输时刻:
发送终端提前第一信号的传输时刻,使调整后的第一信号与第三信号在时间上连续的两个时间间隔上,或者发送终端延迟第一信号的传输时刻,使调整后的第一信号与第二信号在时间上连续的两个时间间隔上,可选的,发送终端还可以通过延迟第一信号的传输时刻,使调整后的第一信号与第三信号之间的发送间隔和第一信号与第二信号之间的发送间隔均大于第一预设值,具体此处不做限定。
1-2、调整第一信号的传输时刻和第二信号的传输时刻:
发送终端调整第一信号的传输时刻和第二信号的传输时刻,使第一信号、第二信号和第三信号在时间上连续的三个时间间隔上;可选的,发送终端可以调整第一信号、第二信号或第三信号中的至少两个信号,使得第一信号、第二信号和第三信号在时间上连续的三个时间间隔上,且调整后第三信号可仅与第一信号相邻、仅与第二信号相邻或在第一信号和第二信号之间,具体此处不做限定。
1-3、调整第三信号的传输时刻:
发送终端提前第三信号的传输时刻,使调整后的第三信号与第一信号之间的发送间隔大于第一预设值。
在图6.b所示的冲突场景2中,其中第一信号以白色长方块表示,第二信号以黑色长方块表示,第三信号以短方块表示,各方块上的箭头表示信号的传输时刻可调整的方向,第一信号与第二信号之间的发送间隔小于第一预设值,第二信号与第三信号之间的发送间隔大于第一预设值,即第一信号与第二信号发生传输冲突,处理的方式包括以下方式:
2-1、丢弃第二信号;
2-2、调整第一信号或第二信号的传输时刻;
发送终端仅延迟第一信号的传输时刻,使调整后的第一信号与第二信号在时间上连续的两个时间间隔上,或发送终端提前第一信号的传输时刻,使调整后的第一信号与第二信号之间的发送间隔大于第一预设值,或发送终端延迟第一信号的传输时刻并提前第二信号的传输时刻,或发送终端同时提前第一信号和第二信号的传输时刻,使调整后的第一信号与第二信号在时间上连续的两个时间间隔上,故发送终端处理的方式具体此处不做限定。
407、发送终端发送指示信息;
发送终端确定冲突情况对应的处理的方式后,为保证接收终端能正确接收到处理后的信号,发送终端发送第四信号,该第四信号为第一信号的上一个周期传输,且第四信号中携带有指示信息,该指示信息用于指示处理的方式。当处理的方式中包括调整第一信号时,第四信号携带有控制信息和数据信息,其中控制信息包括以下之一:
1、第一指示域,该第一指示域用来指示第一信号的传输时刻需要调整的偏移量,当需要调整的偏移量值为零时,即表示第一信号的传输时刻不需要调整;
2、第二指示域和第三指示域,该第二指示域用于指示第一信号的传输时刻是否发生变化,第三指示域用于指示第一信号的传输时刻需要调整的偏移量,例如,假定第二指示域长度为1比特,当第二指示域指示为1时,表示第一信号的传输时刻会发生变化,第三指示域的值有效,当第二指示域指示为0时,表示第一信号的传输时刻不需要调整。
3、第四指示域,该第四指示域用于指示第一信号的传输时刻是否需要调整预置偏移量,例如,假定第四指示域长度为1比特,当第四指示域的域值为1时,表示第一信号的传输时刻调整预置偏移量,当第四指示域的域值为0时,表示第一信号的传输时刻不需要调整。
若处理的方式中包括调整第三信号的传输时刻,则发送终端在物理旁路广播信道(Physical Sidelink Broardcast Channer,PSBCH)上传输第五指示域,其中该第五指示域用来指示第三信号在当前的传输周期内的资源位置是否发生变化,例如当第五指示域的长度为1比特时,第五指示域的域值为1表示第三信号在当前的传输周期内的资源位置发生变化,第五指示域的域值为0时表示该资源位置没变化。
若处理的方式中还包括丢弃第二信号,则第二信号携带的控制信息中还包括第六指示域,可以设定当第六指示域的域值为0时,即表示第二信号被丢弃。
408、发送终端发送处理后的两个相邻的信号;
发送终端根据处理的方式对两个相邻的信号中的至少一个信号进行处理后,将处理后的两个相邻的信号发送给接收终端。
409、接收终端根据指示信息接收两个相邻的信号中的至少一个信号。
接收终端接收到发送终端发送的指示信息后,根据该指示信息正确接收处理后的两个相邻的信号中的至少一个信号。如图7所示,虚线方框表示第一信号的传输位置,较小方框表示第三信号的传输位置,且第一信号与第三信号间的发送间隔小于第一预设值,即第一信号与第三信号间存在传输冲突,发送终端确定调整方式为延迟第一信号的传输时刻,故发送终端在第四信号携带的控制信息中还携带offset域来指示第一信号的传输时刻调整的情况,Tsrv用于表示预留的间隔,故接收终端能根据Tsrv和offset域得知接收第一信号的位置。
本申请实施例中,当待发送的非连续时间间隔上的两个相邻的信号之间的发送间隔小于第一预设值时,发送终端根据确定的处理的方式对发生传输冲突的两个相邻的信号中的至少一个信号进行处理,且处理的方式包括调整信号的传输时刻,相比于现有技术中的丢弃第三信号,本申请实施例在存在传输冲突时调整信号的传输时刻,保证了接收终端同步的性能。
本申请实施例中,当待发送的非连续时间间隔上的两个相邻的信号之间的发送间隔小于第一预设值时,发送终端根据冲突情况在冲突情况与处理的方式的对应关系中确定处理的方式,并根据该处理的方式对发生传输冲突的两个相邻的信号中的至少一个信号进行,且处理的方式包括调整信号的传输时刻或丢弃第二信号并调整第一信号的MCS值,相比于现有技术中的丢弃第三信号,本申请实施例在存在传输冲突时调整信号的传输时刻,保证了接收终端同步的性能,增加了本申请实施例的实现方式。
如图8所示,本申请实施例中终端通信的方法另一个实施例包括:
801、发送终端确定存在冲突情况;
发送终端传输的信号包括第一信号、可能的第二信号和第三信号,其中第二信号为第一信号的重传信号,第三信号为周期固定的信号,由于发送终端在传输信号时会预留多次信号传输的资源,因此发送终端能预先判断可能发生的冲突情况,即第一信号、可能的第二信号和第三信号两两之间在当前或未来传输过程中可能存在非连续时间间隔上的两个相邻的信号间的发送间隔小于第一预设值的情况。发送终端根据待发送信号的参数和信号接收情况确定可能发生的冲突情况,其中待发送信号的参数包括以下至少一种:第一信号的起始发送时刻、第一信号中携带的资源预留间隔、第二信号的起始发送时刻、第二信号中携带的资源预留间隔、第三信号的发送时刻或资源预留次数,其中资源预留次数表示发送终端选择合适的资源后,在后续传输过程中周期性的使用该对应资源的次数,且对应资源是指与初次传输选择的资源在时间上周期发生、频率上位置相同的资源。另外,信号接收情况包括以下至少一种:其他发送终端发送的第三信号的时刻或第三信号的周期。
802、发送终端根据冲突情况对两个相邻的信号中的至少一个信号进行处理。
发送终端确定存在冲突情况后,对两个相邻的信号中的至少一个信号进行处理,其中,处理的方式包括以下方式中的一种或多种:调整第一信号和/或第二信号的起始发送时刻,使得待发送的两个相邻的信号之间的间隔大于预设值,或者将待发送的两个相邻的信号在连续的时间间隔上发送,并且在后续传输中也采用相同的参数配置;或,
调整资源预留次数,使得最后一次资源预留的位置在预计的冲突情况发生之前结束;或,
当预计的冲突情况要发生时,发送终端为第一信号和/或第二信号的传输重新选择资源,使得待发送的两个信号之间的间隔大于预设值,或者待发送的两个信号在连续的时间间隔上发送。
图4所示的实施例中发送终端通过冲突情况与处理的方式的对应关系确定了调整方式,发送终端还可通过优先级准则的方式来确定调整方式,具体如图9所示,本申请实施例中终端通信的方法另一个实施例包括:
901、发送终端确定冲突情况;
902、发送终端获得当前信道的拥塞等级;
本实施例中,步骤901至步骤902与图4中的步骤401至402类似,此处不再赘述。
903、发送终端获得第二优先级准则;
904、发送终端在第二优先级准则中确定与冲突情况对应的处理的方式中优先级最高的 第一处理方式;
发送终端获得当前信道的拥塞等级后,若当前信道的拥塞等级为第二拥塞等级即当前信道的CBR大于第二预设值时,发送终端在预配置或预存储的信息中获得该第二优先级准则,第二优先级准则包括处理的方式的优先级信息,其中发送终端获得第二优先级准则的方式还包括接收基站发送的广播信息,且该广播信息中携带第二优先级准则,故具体此处不做限定。
另外,若当前信道的拥塞等级为第一拥塞等级即当前信道的CBR小于第二预设值时,发送终端从基站发送的广播信息或在本地预配置或预存储的信息中获得对应该第一拥塞等级的第三优先级准则。
可选的,在实际应用中,多个拥塞等级可分别对应多个优先级准则,例如,信道的拥塞等级分为三个等级,分别用于表示信道的CBR小于第三预设值、信道的CBR大于第三预设值小于第四预设值和信道的CBR大于第四预设值时,则可分别对应第四优先级准则、第五优先级准则和第六优先级准则,且不同的拥塞等级对应的优先级准则包括的优先级信息可以相同或互不相同,例如第五优先级准则与第六优先级准则包括的优先级信息相同,而与第四优先级准则包括的优先级信息不同,故具体此处不做限定。
发送终端获得第二优先级准则后,在该第二优先级准则中确定与冲突情况对应的处理的方式中优先级最高的第一处理方式。若发送终端根据当前信道的拥塞等级获得第三优先级准则,则同样在该第三优先级准则中确定与冲突情况对应的处理的方式中优先级最高的第二处理方式。例如,第二拥塞等级对应的第二优先级准则为:丢弃第二信号>调整第一信号的传输时刻>调整第二信号的传输时刻>调整第三信号的传输时刻>调整第一信号的传输时刻和第二信号的传输时刻,第一拥塞等级对应的第三优先级准则为:调整第一信号的传输时刻>调整第二信号的传输时刻>调整第三信号的传输时刻>调整第一信号的传输时刻和第二信号的传输时刻>丢弃第二信号,若发送终端获得的冲突情况为第一信号与第三信号发生传输冲突且当前信道的拥塞等级为第一拥塞等级,则发送终端在第一拥塞等级对应的第三优先级准则中确定第一处理方式为调整第一信号的传输时刻。
可以理解的是,在优先级准则中,处理的方式的优先级信息可以由网络侧设备自定义,且优先级准则中的处理的方式进行优先级分类,如表2所示的第三优先级准则,故优先级准则中处理的方式的显示具体此处不做限定。

906、发送终端发送指示信息;
907、发送终端发送处理后的两个相邻的信号;
908、接收终端根据指示信息接收两个相邻的信号中的至少一个信号。
