When the UE has uplink data to send but no uplink resource, the UE sends an SR on the SR resource and requests the eNodeB to allocate uplink resources. This mechanism increases the system delay.

技术领域
本申请涉及通信技术领域,特别涉及一种资源配置及数据传输的方法和设备。
背景技术
现有LTE(Long Term Evolution,长期演进)提供了一个上行调度请求(Scheduling Request,SR)的机制为,如果UE没有上行数据要传输的情况下,eNodeB(Evolved Node B,演进基站)不需要为该UE分配上行资源,否则会造成资源浪费。因此,UE(User Equipment,用户设备)需要告诉eNodeB自己是否有上行数据需要传输,以便eNodeB决定是否给UE分配上行资源。为此eNodeB可以为每个UE分配一个专用的SR资源用于发送SR,当UE有上行数据需要发送但却没有上行资源时,UE在该SR资源上发送SR,向eNodeB请求分配上行资源,无疑这种机制增加了系统时延。
因此,3GPP(Third Generation Partnership Project,第三代合作伙伴计划)协议提出了预配置资源的概念,网络侧设备可以为终端预先配置资源,预配置资源的类型包括预配置资源类型1和预配置资源类型2,当终端具有业务传输需求时,可以使用该预配置资源进行传输,降低传输时延,节省了终端发 送调度请求,获得上行资源进行缓存上报,再传输数据的时延。
具体为终端配置预配置资源时,网络侧设备与终端可以对终端即将到达的数据起点进行协商,但实际上网络侧设备配置的预配置资源的起点很难与终端到达的数据起点完全匹配,因此终端可能需要再等待下一预配置资源周期来发送数据,因此,虽然预配置资源缓解了传输时延的问题,但对于时延要求高的场景仍不能满足其时延要求,例如目前的5G系统中提出的一个重要的场景—URLLC(Ultra Reliable Low Latency Communications,超高可靠低时延)场景,该场景要求端到端时延达到0.5ms。
综上所述,目前的预配置资源的方式传输时延较大,无法满足5G系统的低时延业务需求。

6、本申请实施例所指的“网络侧设备”是宏基站、微基站等。
本申请实施例描述的应用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,随着新应用场景的出现,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。其中,在本申请的描述中,除非另有说明,“多个”的含义是两个或两个以上。
预配置资源有两种方式,在3GPP协议中称为预配置资源类型1(configured grant Type1)和预配置资源类型2(configured grant Type2)。
configured grant Type1是网络侧用RRC信令为终端配置的周期性资源,网络侧详细地通知终端预配置资源的预配置资源周期、预配置资源的起点位置、传输资源(时频资源等)、传输格式(MCS等)。该预配置资源配置即生 效。终端收到网络侧发送的配置命令后,立即可以使用该周期性资源进行数据传输。如图1所示为网络侧设备为终端配置预配置资源类型1的场景示意图。
configured grant Type2是网络侧用RRC信令为终端分配周期性资源的周期和用于调度该周期性资源的CS-RNTI。在网络侧决定分配实际资源的时候,发送PDCCH命令指示该周期性资源的起点和具体传输资源(时频资源等)、传输格式(MCS等)。终端在收到预配置资源的RRC信令的时候并没有资源可用,要收到PDCCH的激活命令后才实际分配了预配置资源。如图2所示为网络侧设备为终端配置预配置资源类型2的场景示意图。
网络侧设备为终端分配预配置资源时,可以由网络侧设备预估资源起点,大致与终端的业务对齐,也可以由终端预估数据到达的世界,将业务模型进行上报,由网络侧设备和终端对配置给终端的预配置资源的起点位置进行协商。当终端的数据到达以后,终端可以使用该预配置资源进行数据上报。但预配置资源的起点很难与终端到达的数据匹配,因此终端可能需要再等待下一预配置资源周期来发送数据,参考如图3所示的场景。
因此造成的传输时延对于一般的低时延要求的场景来说没有影响,但对于时延要求严格的场景,比如5G技术中提出的一个重要的测试场景—URLLC场景,URLLC场景适用于工业应用和控制、交通安全和控制、远程制造、远程培训、远程手术,该场景要求端到端时延可以达到0.5ms(毫秒),由于现有预配置资源难以与终端到达的数据匹配导致的传输时延很可以造成上述场景不能满足时延的要求。
因此,本申请实施例提出了一种资源配置及数据传输的方法和设备,网络侧设备预先为终端配置预配置资源,其中,一套预配置资源的一个预配置资源周期内有多个连续资源分配,即使该预配置资源的起点与终端即将到达的数据的起点不匹配,终端还可以在多个连个的资源内选择最接近的资源进行数据传输。下面结合说明书附图对本申请实施例做进一步详细描述。
如图4所示,本申请实施例提供的是一种资源配置和数据传输的系统, 该系统包括:网络侧设备10和终端20。
网络侧设备10,用于确定在配置给终端的一套预配置资源中,一个预配置资源周期内的多个连续资源;为终端预配置确定的多个连续资源。
终端20,用于确定网络侧设备预配置的多个连续资源;通过所述预配置的多个连续资源进行数据传输。
通过上述方法,网络侧设备预先为终端配置预配置资源,其中,一套预配置资源的一个预配置资源周期内有多个连续资源分配。当终端有数据到达时,在多个连续的预分配资源中选择一个进行数据传输,即使该预配置资源的起点与终端即将到达的数据的起点不匹配,终端还可以在多个连个的资源内选择最接近的资源进行数据传输,因此降低了传输时延。
下面对预配置资源类型1和预配置资源类型2的配置过程进行介绍:
一、网络侧设备配置预配置资源过程:
1、配置预配置资源类型1的过程:网络侧设备根据终端上报的业务到达周期,业务数据预计到达时间,预计数据包大小、业务数据预计到达时间的偏差等辅助信息为终端配置预配置资源,针对每套预配置资源,确定预配置资源的第一资源周期的时间起点、时频资源位置、传输格式等。其中,对于业务数据预计到达时间的偏差的理解:该业务数据预计到达时间的偏差有正负之分,该偏差值的单位可以是符号、时隙、子帧或毫秒。网络侧设备根据业务数据预计到达时间和业务数据预计到达时间的偏差确定一个预配置资源周期内的多个连续资源的个数。
比如,如图5所示,终端上报业务数据预计到达时间为子帧N的第3个符号,业务数据预计到达时间的偏差为正的2个符号,则网络侧设备确定终端业务数据可能延后2个符号到达,因此网络侧设备确定一个预配置资源周期内多个连续资源个数至少为3个,具体为:起点是子帧N的第3个符号,连续分配3个资源,设业务周期为T子帧,则每个子帧N+kT的第3个符号开始预分配3个资源。
网络侧设备通过RRC信令指示一个预配置资源周期内连续资源的个数;
2、配置预配置资源类型2的过程:网络侧设备根据终端上报的业务到达周期,业务数据预计到达时间,预计数据包大小、业务数据预计到达时间的偏差等辅助信息为终端配置预配置资源,针对每套预配置资源,确定预配置资源的第一资源周期的时间起点、时频资源位置、传输格式等,其中对于确定连续资源的个数的方式可以参数上述方式,此处不再赘述。网络侧设备通过下列方式指示预配置资源类型2中一个预配置资源周期内连续资源的个数:
指示方式一:通过RRC信令指示;
网络侧设备可以通过RRC信令为终端配置并指示一个预配置资源周期内连续资源的个数。
指示方式二:通过用于激活预配置资源的PDCCH命令指示;
网络侧设备可以通过用于激活预配置资源的PDCCH命令指示一个预配置资源周期内连续资源的个数。
本申请实施例中的不管是预配置资源类型1还是预配置资源类型2,网络侧设备为终端配置的一套预配置资源中,一个预配置资源周期内具有多个连续资源,对于“多个连续”可以理解为如下:
1、相邻符号上连续资源;
2、相邻时隙上连续资源;
3、相邻子帧上连续资源;
4、相邻的连续同方向传输资源;
如图6所示,相邻的连续同方向传输资源是指同一个终端连续发送或连续接收的资源,包括连续上行资源,或连续sidelink资源。
若相邻的连续同方向传输资源是sidelink资源,则预配置资源是网络侧设备配置给发送终端和接收终端在sidelink接口上传输的。
二、使能预配置资源并释放同一周期内其他预配置资源的过程:
终端接收到网络侧设备配置预配置资源的RRC信令,确定网络侧设备配置的多个连续资源,该预配置资源的一个预配置资源周期内的多个连续资源都可以认为是预留给终端的。当终端确定有业务数据到达后,在预配置资源 上选择一个资源进行数据上报,网络侧设备确定终端使用预配置资源发送第一个数据包后,使能每个预配置资源周期内相同位置的资源,同一预配置资源周期内其它预配置资源失效,网络侧设备对所述终端释放多个预配置的资源中未使能的资源,每个预配置资源周期内只有一个使能的资源,之后终端可以在使能的资源上进行数据传输。
其中,网络侧设备通过下列方式确定终端发送第一个数据包的资源位置:
确定方式一:根据预配置资源上终端的发送功率值确定;
网络侧设备进行功率检测,确定在多个预配置资源上终端的发送功率最大值对应的资源为终端发送第一个数据包的资源。
确定方式二:根据解码出的数据包确定;
网络侧设备接收终端的上报信息,并对上报信息进行解码,网络侧设备可以根据是否解码出数据包的方式确定终端发送第一个数据包使用的预配置资源,若网络侧设备解码出数据包,则确定终端此次上报信息使用的资源为终端发送第一个数据包的资源。
确定方式三:根据终端上报的指示信息确定;
终端在数据传输包中携带指示信息,并在预配置的多个连续资源中选择一个资源进行数据上报,网络侧设备将预配置的多个连续资源中承载终端发送的包含指示信息的数据包的资源作为终端发送第一个数据包的资源。
其中,所述指示信息由MAC层承载指示信息为MAC CE,或通过携带专用指示LCID的MAC子头。
其中,对于预配置资源类型1,如图7所示为预配置资源类型1的配置及使能的场景示意图。
其中,T为预配置资源周期,一个预配置资源周期内有4个连续的资源,对于预配置资源类型1,网络侧设备通过RRC信令配置后即生效,当终端的数据到达后,终端在多个连续资源上选择与到达时间最接近的资源来发送数据,网络侧设备确定终端在预配置资源上发送第一个数据包后,使能每个预配置资源周期内与终端发送第一个数据包的资源位置相同的资源,其他预配 置资源失效,网络侧设备对所述终端释放多个预配置的资源中未使能的资源,之后终端在使能的资源上进行数据传输。
对于预配置资源类型2,如图8所示,为网络侧设备为终端配置及使能预配置资源类型2的场景示意图。
其中,T为预配置资源周期,一个预配置资源周期内有4个连续的资源,与预配置资源类型1不同点在于,对于预配置资源类型2,网络侧设备通过RRC信令配置后还需要通过激活预配置资源的PDCCH命令激活该资源,激活后的资源才能被终端使用,当终端的数据到达后,在已激活的多个连续资源上选择与到达时间最接近的资源来发送数据,终端发送第一个数据包的资源之后,使能每个预配置资源周期内相同的资源位置的资源,其他预配置资源失效,网络侧设备对所述终端释放多个预配置的资源中未使能的资源,终端在使能的资源上进行数据传输,失效的资源可以配置给其他终端使用,也可以动态调度给该终端。
三、去使能预配置资源的过程:
在使能预配置资源后,一个预配置资源周期内仅有一个使能的预配置的资源,终端在使能的预配置的资源上进行数据传输,若在满足网络侧设备配置的去使能条件后,比如终端长时间未在使能的预配置的资源上发送数据,则将该使能的资源去使能,即回退到已激活未使能的状态。
对于预配置资源类型1和预配置资源类型2的去使能方式介绍如下:
去使能方式一:通过定时器或计数器去使能预配置资源;
以定时器为例进行介绍:网络侧设备通过定时器设置去使能预配置资源的使用时长,在预配置资源已激活未使能之前,终端在预配置资源上发送第一个数据包的同时启动或重启该定时器,如果该定时器在达到去使能的时长后,终端未在后续N个预配置资源周期内使能的预配置资源上发送数据,则终端认为该预配置资源去使能,即终端不通过该资源发送数据。假设N为1,如图9所示为网络侧设备通过定时器去使能预配置资源类型1的场景示意图。图9对使能资源和在使能资源有数据传输进行了区分,此处使能资源为已使 能但终端未在该资源上进行数据传输,同图10及图11,下文不再赘述。
当定时器定时时长达到预配置资源去使能的使用时长后,终端根据超过所述使用时长后的1个预配置资源周期内终端是否发送数据判断是否去使能预配置资源,若终端在后续的1个预配置资源周期内使能的资源上发送了数据,则不对预配置资源去使能,若再之后的预配置资源周期内终端没有业务数据时,即终端不再通过预配置资源发送数据,则认为预配置资源去使能,即回退到一个预配置资源周期内具有多个连续资源的状态。
又比如,若N为大于1的正整数,假设N为2,则当终端在确定达到或超过去使能预配置的使用时长后,若在之后的2个预配置资源周期内终端都没有通过使能的资源发送数据,则认为该预配置资源去使能。如图10所示为N为2时网络侧设备通过定时器去使能预配置资源类型1的场景示意图。终端根据超过所述使用时长后的2个预配置资源周期内终端是否发送数据判断是否去使能预配置资源,若终端在后续的第1个预配置资源周期内使能的资源上发送了数据,则不对预配置资源去使能,若再之后的2个(超过T1后的第2个预配置资源周期和第3个预配置资源周期)预配置资源周期内终端没有业务数据时,即终端不再通过预配置资源发送数据,则在第2个没有使用预配置资源发送数据的预配置资源周期去使能预配置资源,即回退到一个预配置资源周期内具有多个连续资源的状态。
网络侧设备还可以通过计数器设置去使能预配置资源的使用个数,其中,计数器的具体执行方式可以参见上述定时器的方法步骤,此处不再赘述。
其中,去使能的使用时长或使用个数可以是协议规定的,或是网络侧设备通过RRC信令为终端配置的。比如,网络侧设备通过配置预配置资源的RRC信令指示去使能的使用时长。
需要说明的是,若定时器计时时长达到去使能预配置资源的使用时长或使用预配置资源发送数据的个数达到去使能预配置资源的使用个数后,若终端还有业务传输需求,则终端还可以继续在后续的预配置资源上发送数据,直到终端不再通过预配置资源发送数据,则认为该预配置资源去使能。如图 11所示的场景。
去使能方式二:通过MAC层承载的去使能命令去使能预配置资源;
网络侧设备接收所述终端发送的去使能预配置资源的指示信息,所述指示信息为包含带指示去使能预配置资源的LCID的MAC子头,或
网络侧设备通过MAC CE中携带的去使能预配置资源的预配置资源编号,去使能预配置资源编号对应的预配置资源。
其中,若通过MAC子头中的LCID指示去使能预配置资源,则该MAC子头中的LCID的值可以为协议中指示去使能预配置资源的规定值,若所述终端发送的MAC子头中的LCID的值为所述去使能预配置资源的规定值,则网络侧设备确定对所述终端配置的预配置资源去使能。其中,具体MAC子PDU的格式为图11中不包含MAC CE的部分。
若所述指示信息为MAC CE,如图12所示,其中CG(configured grant,配置授权)index为预配置资源编号,该MAC CE可以采用上述方式中的MAC子头,该MAC子头可以携带指示对应的MAC CE为去使能预配置资源的MAC CE,并根据MAC CE中携带的去使能预配置资源的预配置资源编号去使能所述预配置资源编号对应的预配置资源。图11为一个示例,具体MAC CE中指示预配置资源编号的比特数可以根据需要调整。
比如,网络侧设备为终端配置的预配置资源的预配置资源编号为3,终端向所述预配置资源编号3置于MAC CE1中,并通过MAC子头中的LCID携带指示去使能预配置资源的MAC CE为MAC CE1,则网络侧设备根据接收到MAC CE1携带的指示信息去使能预配置资源编号3对应的预配置资源。其中所述MAC CE1中的预配置资源编号对应需要去使能的预配置资源,也可以通过配置预配置资源编号的值确定需要去使能的预配置资源。比如将图11中MAC CE中的CG index3的值置为1(或置为0),以指示将预配置资源编号为3的预配置资源去使能。
需要说明的是,对于预配置资源类型1,网络侧设备通过下列方式去使能预配置资源:
去使能方式三:通过RRC信令去使能预配置资源;
网络侧设备通过RRC信令重新配置具有相同预配置资源编号的预配置资源,则当前具有相同预配资源编号的已使能的预配置资源去使能。
比如,如图13所示,网络侧设备为终端配置预配置资源编号为1的预配置资源,终端在该预配置资源上发送数据,该预配置资源的一个预配置资源周期内有一个使能的资源。当网络侧设备再次通过RRC信令重新配置预配置资源编号为1的预配置资源时,当前预配置资源编号为1的资源去使能,并根据重配置预配置资源的RRC信令确定新的预配置资源。其中,预配置资源编号是针对一套预配置资源而言的,与下文中的预配置资源的资源编号相区分,资源编号是针对一个预配置资源周期中的一个资源的编号。
需要说明的是,根据重配置预配置资源的RRC信令确定的新的预配置资源可能与之前的预配置资源的配置相同,也可能不同。
四、释放已使能的预配置资源类型2的资源;
释放方式一:通过定时器或计数器释放预配置资源;
以计数器为例,网络侧设备通过计数器设置释放预配置资源的使用个数,终端每通过预配置资源发送数据,则计数器加1,当达到释放预配置资源的使用个数后,终端未在后续N个预配置资源周期内使能的预配置资源上发送数据,则终端认为该预配置资源已释放。假设N为1,如图14所示为网络侧设备通过计数器释放预配置资源类型2的场景示意图。
其中,释放预配置资源的使用时长或使用个数可以是协议规定的,或是网络侧设备通过RRC信令为终端配置的或是由激活预配置资源的PDCCH命令指示的。比如,网络侧设备通过配置预配置资源的RRC信令指示去使能的使用时长。
需要说明的是,若定时器计时时长达到释放预配置资源的使用时长或使用预配置资源发送数据的个数达到释放预配置资源的使用个数后,若终端还有业务传输需求,则终端还可以继续在后续的预配置资源上发送数据,直到终端不再通过预配置资源发送数据,则认为该预配置资源被释放。
释放方式二:通过MAC层承载的释放资源命令释放预配置资源;
网络侧设备根据终端发送的包含释放预配置资源的指示信息释放预配置资源,该指示信息承载与MAC层,网络侧设备可以通过一个单独的MAC CE承载去使能命令,网络侧设备根据MAC CE中包含的携带指示释放预配置资源的LCID的MAC字头;或
网络侧设备通过MAC CE中携带的释放预配置资源的预配置资源编号,释放预配置资源编号对应的预配置资源。
释放方式三:通过RRC信令释放预配置资源;
网络侧设备通过RRC信令重新配置具有相同预配置资源编号的预配置资源,则释放当前具有相同预配资源编号的已使能的预配置资源。
释放方式四:通过新的激活预配置资源的PDCCH命令释放预配置资源;
网络侧通过新的激活相同预配置资源编号的预配置资源的PDCCH命令激活新的资源配置,可以理解的是,在激活新的预配置资源时,释放之前该预配置资源编号中已激活并使能的预配置资源。
比如,如图15所示,网络侧设备为终端配置预配置资源编号为2的预配置资源类型2的资源,并通过PDCCH命令激活该资源,终端在该预配置资源上发送数据,当网络侧设备为终端配置了一套新的预配置资源,且该预配置资源的预配置资源编号也是2时,网络侧设备向终端发送激活最新配置的预配置资源的PDCCH命令,释放当前已激活并使能的预配置资源编号为2的资源,并根据新的激活预配置资源的PDCCH命令确定新的预配置资源。
需要说明的是,对于新的激活预配置资源的PDCCH命令中“新的”可以理解为相对于激活现有预配置资源的PDCCH命令之后网络侧设备发送的PDCCH命令,且根据新的激活预配置资源的PDCCH命令确定的新的预配置资源可能与之前的预配置资源的配置相同,也可以不同。
