目标业务的可靠性要求:ProSe Per-packet reliability,PPPR,即,近场通信单包可靠性要求,不同的PPPR数值代表了不同的可靠性要求。
第一配置参数:也称为“第一配置”,在本申请实施例中,第一配置参数包含诸如目标业务的可靠性要求、信道繁忙率等第一指标与是否对目标业务的数据进行复制和传输的对应关系,也就是说,可以根据第一配置参数以及第一指标,确定是否对目标业务的数据进行复制传输。
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请的实施方式作进一步地详细描述。
本申请的技术方案可以应用于各种终端到终端通信系统,例如车联网等。
下面先说明一下本申请实施例所应用的场景架构。
如上文提到的,在3GPP Rel-14中对车联网技术(V2X)进行了标准化,定义了两种传输模式:模式3和模式4。
具体的,对于模式3,如图1所示,车载终端的传输资源是由基站分配的,车载终端根据基站分配的资源在侧行链路上进行数据的发送;基站可以为终端分配单次传输的资源,也可以为终端分配半静态传输的资源。
具体的,对于模式4,如图2所示,车载终端采用侦听(sensing)+预留(reservation)的传输方式。车载终端在资源池中通过侦听的方式获取可用的传输资源集合,终端从该集合中随机选取一个资源进行数据的传输。
由于车联网系统中的业务具有周期性特征,因此终端通常采用半静态 传输的方式,即终端选取一个传输资源后,就会在多个传输周期中持续的使用该资源,从而降低资源重选以及资源冲突的概率。
终端会在本次传输的控制信息中携带预留下次传输资源的信息,从而使得其他终端可以通过检测该用户的控制信息判断这块资源是否被该用户预留和使用,达到降低资源冲突的目的。
另外,本申请实施例应用到了载波聚合。
具体的,对于载波聚合(carrier aggregation,CA),支持数据复制传输(data duplication)的方案利用PDCP的复制数据功能,使复制的PDCP PDU分别传输到两个RLC entity(两个不同的逻辑信道),并最终保证复制的PDCP PDU能够在不同物理层聚合载波上传输,从而达到频率分集增益以提高数据传输可靠性。具体的协议结构如图3所示。
本发明第一实施方式涉及一种通信系统中控制用户设备进行复制传输的方法。图4是该通信系统中控制用户设备进行复制传输的方法的流程示意图。该方法包括以下步骤:
在步骤401中,用户设备获取包含目标业务的可靠性要求的第一指标和第一配置,其中第一配置包含目标业务的可靠性要求和是否进行复制传输的第一对应关系。
在步骤402中,根据所获取的第一指标和第一配置,确定用户设备是否对目标业务的数据进行复制传输。
代表目标业务可靠性要求的指标和配置的方式可以是多种多样的,下面举几个实施例。
实施例1:预先设定一个可靠性要求门限(即第一门限),当目标业务的可靠性要求高于,或高于等于该门限(即代表目标业务可靠性要求的指标高于,或高于等于第一门限),则用户设备进行数据复制传输。或者如果第一指标低于,或低于等于第一门限,则确定用户设备对目标业务的数据进行复制传输。其中,代表目标业务可靠性要求的指标可以是误码率、误比特率、误块率、正确传输概率等。
实施例2:第一配置可以结合通信系统的信道繁忙率channel busy ratio(CBR)设定。
可选地,可以当CBR变化时,改变第一配置。例如某个用户设备的当前配置为进行数据复制传输,当CBR变化时,网络侧将该用户设备的当前 配置改变为不进行数据复制传输。
可选地,配置一个表(即第二对应关系,该表包括信道繁忙率与是否进行复制传输的对应关系)。在步骤402中,用户设备根据自身测量得到的信道繁忙率值,查询第二对应关系,根据查询结果确定是否对目标业务的数据进行复制传输。
可选地,配置一个门限(即第二门限),在步骤402中,如果用户设备自身测量得到的信道繁忙率值低于,或者低于等于第二门限,则对目标业务的数据进行复制传输。
实施例3:依据不同的可靠性要求设定的第一配置可以根据目标业务的优先级PPPP(prose per packet priority)不同而不同。
可选地,配置一个表(即第三对应关系,其中包括信道繁忙率与是否进行复制传输的对应关系),在步骤402中,用户设备根据自身测量得到的目标业务的优先级,查询第三对应关系,根据查询结果确定是否对目标业务的数据进行复制传输。
可选地,配置一个门限(即第三门限),在步骤402中,如果用户设备自身测量得到的目标业务的优先级值低于,或者低于等于第三门限,则对目标业务的数据进行复制传输。
可选地,配置包括一个集合,在步骤402中,如果用户设备自身测量得到的目标业务的优先级值属于集合,则对目标业务的数据进行复制传输。
可选地,配置一个PPPP和载波的映射关系,在步骤402中,如果用户设备根据自身测量得到的目标业务的优先级值和映射关系,判定目标业务的优先级值被映射到多于一个载波,则对目标业务的数据进行复制传输。可选地,用户设备根据目标业务的优先级值和映射关系,确定可以对所述目标业务的数据进行复制传输的载波。
当配置可以根据目标业务的优先级PPPP不同而不同时,可以更进一步地配置复制数据的逻辑信道和载波的映射关系。
可选地,对于不同的PPPP,配置原数据以及复制数据和载波的映射关系,例如对于PPPP1,将原数据以及复制数据分别放到载波A和B上。
可选地,对于不同的PPPP,分别配置逻辑信道和载波的映射关系,例如对于PPPP1,映射到逻辑信道I和II上,将I和II分别放到载波A 和B上配置复制数据的逻辑信道和载波的映射关系。
实施例4:分别根据可靠性要求和信道繁忙率,确定是否对目标业务的数据进行复制,以及确定是否对已复制的目标业务的数据的副本进行传输。
具体的,在实施例4中,第一对应关系包括:可靠性要求和是否进行复制传输中的复制处理的对应关系;
相应地,根据第一指标和第一对应关系确定是否进行目标业务数据的复制处理。具体的,第一对应关系包括第四门限,如果可靠性要求大于,或者大于等于第四门限,则确定用户设备对目标业务的数据进行复制处理。
可选的,在本申请的一些实施例中,也可以配置为:如果可靠性要求低于,或低于等于第四门限,则确定用户设备对目标业务的数据进行复制处理。
之所以可以根据灵活设置可靠性要求的配置参数,是因为,虽然目前可靠性要求可以具有8个级别,通过1-8表示,其中,8表示可靠性要求最高。但本申请实施例并不限于这种情况,例如,在一些实施例中,也可以有更多的级别,或者由1表示可靠性要求最高,等等。因此,在这种情况下,具体的配置或配置参数不限于上述具体的实施例。
另外,第一指标还包括通信系统的信道繁忙率;
相应地,第一配置还包括:信道繁忙率和是否进行复制传输中的传输处理的第四对应关系。换句话说,根据第一指标中的信道繁忙率和第四对应关系确定是否对已经被复制的目标业务数据的副本进行传输处理。
具体的,第四对应关系包括第五门限,如果用户设备的信道繁忙率低于,或者低于等于第五门限,则确定对已经被复制的目标业务数据的副本进行传输处理。
具体的说,参见图5,在实施例4中包含以下步骤:
步骤501:获取第一指标和第一配置信息。
具体的,第一指标中既包含可靠性要求,也包含信道繁忙率。
相应的,第一配置信息包含第一对应关系和第四对应关系。
其中,第一对应关系包括:可靠性要求和是否进行复制传输中的复制 处理的对应关系。具体的,第一对应关系包括第四门限,根据实施例4的配置,如果可靠性要求大于,或者大于等于第四门限,则确定用户设备对目标业务的数据进行复制处理。
其中,第四对应关系包括:信道繁忙率和是否进行复制传输中的传输处理的对应关系。具体的,第四对应关系包括第五门限,根据实施例4的配置,如果用户设备的信道繁忙率低于,或者低于等于第五门限,则确定对已经被复制的目标业务数据的副本进行传输处理。
步骤502:根据第一指标中的可靠性要求和第一对应关系确定是否进行目标业务数据的复制处理。
具体的,第一对应关系包括第四门限,如果可靠性要求大于,或者大于等于第四门限,则确定用户设备对目标业务的数据进行复制处理,并执行步骤503,否则,流程结束。
步骤503:用户设备对目标业务的数据进行复制处理。
步骤504:根据第一指标中的信道繁忙率和第四对应关系确定是否对已经被复制的目标业务数据的副本进行传输处理。
具体的,第四对应关系包括第五门限,如果用户设备的信道繁忙率低于,或者低于等于第五门限,则确定对已经被复制的目标业务数据的副本进行传输处理,并执行步骤505,否则,流程结束。
步骤505:对已经被复制的目标业务数据的副本进行传输处理。
在实施例4中,考虑到了信道繁忙率的实时变化较频繁,而目标业务的可靠性要求则是一个相对静态的值的特点,在这种情况下,如果直接在确定信道繁忙率达到门限要求的情况下,再启动对目标业务的数据进行判断和复制,则有可能在尚未来不及完成目标业务的数据复制和传输之前,信道繁忙率已经发生了变化,有可能已经不再适合对所复制的副本进行传输。因此,实施例4中创新的提出了一种具体的改进方式,先根据可靠性要求确定是否进行复制,如果满足可靠性要求,则直接进行复制;另外,根据信道繁忙率确定是否当前适合对复制的副本进行传输,如果满足信道繁忙率要求,则直接进行传输,如果当前信道繁忙,则可以先对复制的副本进行缓存,等信道繁忙率再次满足要求的时候,再进行传输。
这样做的好处在于:使目标业务的数据的复制和发送方式更加灵活,更充分合理地利用系统资源,更好地确保满足可靠性要求的目标业务的数 据得到尽可能及时的复制和传输。
上面描述了4个实施例,但本申请并不限于这4个实施例。而且这4个实施例即可独立地实施,也可以将4个实施例中各种设置条件以任意方式组合来体现可靠性要求。可选地,可以在设置中包括误码率、CBR和PPPP的一个或多个组合条件,当某个组合条件满足时,对目标业务的数据进行(或不进行)复制传输。可选地,可靠性要求是CBR和PPPP的配置的特定组合,当该组合的可靠性要求得到满足,则对目标业务的数据进行复制传输,该特定组合可以是根据实际需要设置,例如CBR低于,或者低于等于一个门限并且PPPP低于,或者低于等于另一个门限,又如CBR低于,或者低于等于一个门限并且PPPP被映射到多于一个的载波,再如CBR处于一个预定的范围中并且PPPP属于一个预先设定的集合,等等。
本发明第二实施方式涉及一种通信系统中控制用户设备进行复制传输的设备。该设备包括:
获取单元,用于获取包含目标业务的可靠性要求的第一指标和第一配置,其中第一配置包含目标业务的可靠性要求和是否进行复制传输的第一对应关系。可选地,配置可以存储在用户设备的存储器中,控制单元可以是一个处理器或逻辑控制电路。
控制单元,用于根据所述第一指标和所述第一配置,确定用户设备是否对所述目标业务的数据进行复制传输。
代表目标业务可靠性要求的指标和配置的方式可以是多种多样的,下面举几个实施例。
实施例5:在第一配置中预先设定一个可靠性要求门限(即第一门限),控制单元进行判断,当目标业务的可靠性要求高于,或高于等于该门限(即代表目标业务可靠性要求的指标高于,或高于等于第一门限),则进行数据复制传输;当目标业务的可靠性要求低于,或者低于等于该门限(即代表目标业务可靠性要求的指标高于,或高于等于第一门限),则不进行数据复制传输。其中,代表目标业务可靠性要求的指标可以是误码率、误比特率、误块率、正确传输概率等。
实施例6:第一配置可以结合系统的CBR设定。
可选地,可以当CBR变化时,改变配置。例如某个用户设备的当前配置为不进行数据复制传输,当CBR变化时,网络侧将该用户设备的当前配置改变为进行数据复制传输。
可选地,配置一个表(即第二对应关系,该表包括信道繁忙率与是否进行复制传输的对应关系)。控制单元根据用户设备自身测量得到的信道繁忙率值,查询第二对应关系,根据查询结果确定是否对目标业务的数据进行复制传输。
可选地,配置一个门限(即第二门限),控制单元判断,如果用户设备自身测量得到的信道繁忙率值低于,或者低于等于第二门限,则对目标业务的数据进行复制传输。
实施例7:上述依据不同的可靠性要求设定的第一配置可以根据目标业务的优先级PPPP不同而不同。
可选地,配置一个表(即第三对应关系,其中包括目标业务的优先级与是否进行复制传输的对应关系),控制单元根据用户设备自身测量得到的目标业务的优先级查询第三对应关系,根据查询结果确定是否对目标业务的数据进行复制传输。
可选地,配置一个门限(即第三门限),控制单元判断,如果用户设备自身测量得到的目标业务的优先级值低于,或者低于等于第三门限,则对目标业务的数据进行复制传输。
可选地,配置包括一个集合,控制单元判断,如果用户设备自身测量得到的目标业务的优先级值属于集合,则对目标业务的数据进行复制传输。
可选地,配置一个PPPP和载波的映射关系,控制单元判断,如果用户设备根据自身测量得到的目标业务的优先级值和映射关系,判定目标业务的优先级值被映射到多于一个载波,则对目标业务的数据进行复制传输。可选地,用户设备根据目标业务的优先级值和该映射关系,确定可以对目标业务的数据进行复制传输的载波。
可选地,该装置中还可以包括映射关系配置单元,用于配置复制数据的逻辑信道和载波的映射关系。映射关系配置单元有多种配置方法,例如,对于不同的目标业务的优先级,配置原数据以及复制数据和载波的映射关系;又如,对于不同的目标业务的优先级,分别配置逻辑信道和载波的映射关系。
实施例8:分别根据可靠性要求和信道繁忙率,确定是否对目标业务的数据进行复制,以及确定是否对已复制的目标业务的数据的副本进行传输。
具体的,在实施例8中,第一指标包含可靠性要求,以及信道繁忙率。第一配置包含第一对应关系和第四对应关系。
其中,第一对应关系包括:可靠性要求和是否进行复制传输中的复制处理的对应关系;具体的,第一对应关系包括第四门限,如果可靠性要求大于,或者大于等于第四门限,则确定用户设备对目标业务的数据进行复制处理。
其中,第四对应关系包括:信道繁忙率和是否进行复制传输中的传输处理的对应关系;具体的,第四对应关系包括第五门限,如果可靠性要求大于,或者大于等于第四门限,则确定用户设备对目标业务的数据进行复制处理。
并且,控制单元还用于,根据第一指标中的可靠性要求和第一对应关系确定是否进行目标业务数据的复制处理。具体的,如果可靠性要求大于,或者大于等于第四门限,则确定用户设备对目标业务的数据进行复制处理。
可选的,控制单元还用于,根据第一指标中的信道繁忙率和第四对应关系确定是否对已经被复制的目标业务数据的副本进行传输处理。具体的,如果用户设备的信道繁忙率低于,或者低于等于第五门限,则确定对已经被复制的目标业务数据的副本进行传输处理。
在实施例8中,同样的,考虑到了信道繁忙率的实时变化较频繁,而目标业务的可靠性要求则是一个相对静态的值的特点,在这种情况下,如果直接在确定信道繁忙率达到门限要求的情况下,再启动对目标业务的数据进行判断和复制,则有可能在尚未来不及完成目标业务的数据复制和传输之前,信道繁忙率已经发生了变化,有可能已经不再适合对所复制的副本进行传输。因此,实施例8中,先根据可靠性要求确定是否进行复制,如果满足可靠性要求,则直接进行复制;另外,根据信道繁忙率确定是否当前适合对复制的副本进行传输,如果满足信道繁忙率要求,则直接进行传输,如果当前信道繁忙,则可以先对复制的副本进行缓存,等信道繁忙率再次满足要求的时候,再进行传输。
这样做的好处在于:使目标业务的数据的复制和发送方式更加灵活, 更充分合理地利用系统资源,更好地确保满足可靠性要求的目标业务的数据得到尽可能及时的复制和传输。
