Description
本申请要求在2019年07月19日提交中国专利局、申请号为201910654185.0的中国专利申请的优先权,该申请的全部内容通过引用结合在本申请中。
本公开涉及通信领域,例如,涉及一种资源配置的确定方法及装置、资源配置的指示方法及装置、电子装置、存储介质。
随着无线通信技术的发展和用户对通信需求的日益增加,为了满足更高、更快和更新的通信需要,第五代移动通信(5G,5th Generation)技术已成为未来网络发展的趋势。
在边链路(Sidelink,也称为直传链路,Direct link)通信***中,用户设备(User Equipment,UE)之间有业务需要传输时,UE之间的业务数据不经过网络侧,即不经过UE与基站之间的蜂窝链路的转发,而是直接由数据源UE通过Sidelink传输给目标UE,图1为相关技术中Sidelink通信结构的示意图,如图1所示,这种UE与UE之间直接进行通信的模式具有明显区别于传统蜂窝***通信模式的特征,对于能够应用Sidelink通信的近距离通信用户来说,Sidelink通信不但节省了无线频谱资源,而且降低了核心网的数据传输压力,能够减少***资源占用,增加蜂窝通信***频谱效率,降低终端发射功耗,并在很大程度上节省网络运营成本。
在5G通信***中,时域资源的最小粒度是符号(symbol),符号可以分为:循环前缀正交频分复用符号(CP-OFDM,Cyclic Prefix-Orthogonal Frequency Division Multiplex),或者基于离散傅氏变换的OFDM符号(DFT-S-OFDM,Discrete Fourier Transform Spread OFDM)。
一个时隙(slot)包括:12个长循环前缀(extend CP,extend Cyclic Prefix)或14个普通循环前缀(normal CP)的连续符号,图2是相关技术中5G***中时隙的展示示意图。如图2所示,或者,可以由一个或多个连续的符号(小于或等于7个符号)构成迷你时隙(mini-slot)。频域上,资源的最小粒度为子载波(sub-carrier),根据不同的***配置,每个子载波包含的频域宽度不同,包括以下任意一种或多种:15kHz,30kHz,60kHz,120kHz,240kHz。由12个连 续子载波可构成一个频域资源块(RB,resource block)。如上所述,符号或时隙或mini-slot是5G***中的时域资源配置的资源单元,RB是频域资源配置的资源单元,在5G通信***中实现Sidelink通信时,也应采用相同的时域和频域资源单元为基础,实现Sidelink资源的配置。
在5G***中,基站会为蜂窝链路UE指示用于蜂窝通信的时域和频域资源配置。包括时域上的符号及slot划分,以及每个符号的类型;频域上包括子载波和RB的划分。其中,时域上,有三种符号类型:下行符号(Downlink symbol,DL symbol),上行符号(Uplink symbol,UL symbol),以及灵活符号(F symbol)。每个slot中的每个符号都可配置为上述三种符号类型中的任意一种。图3为相关技术中5G***中时隙中符号类型配置的实例的示意图。如图3所示的示例,例#1中包含5个DL symbol(如图3中的斜线阴影小方格所示),5个UL symbol(如图3中的横线阴影小方格所示),以及4个Flexible symbol(如图3中的空白小方格所示)。其中,DL symbol用于承载下行信号,即从基站发送给UE的信号;UL symbol用于承载上行信号,即UE发送给基站的信号;Flexible符号为灵活可重配置的符号,也就是说,F symbol可被重配置为DL symbol或UL symbol。之外,已被配置为DL symbol或UL symbol的符号不能改变符号类型。每个slot中的符号类型及位置由***通过信令配置指示。Slot中符号配置的其他实例如图3中所示,这里不再赘述。
当在5G通信***中实现Sidelink通信时,Sidelink与蜂窝通信共享资源,需同时保障二者的资源配置不冲突。由于5G蜂窝通信中采用了灵活的资源配置方案以及调度指示方式,尚无方案解决如何在5G***中实现蜂窝通信资源与Sidelink通信资源的协调配置问题。

在Sidelink通信***中,UE之间使用Sidelink资源进行信息的传输,根据应用场景及业务类型等,Sidelink通信方式包括但不限于:设备到设备(D2D, Device to Device)通信,车辆到车辆(V2V,Vehicle to Vehicle)通信等。在相关技术的Sidelink通信中,UE使用边链路资源池(Sidelink resource pool)中的资源发送Sidelink信号。其中,边链路资源池包括:
物理边链路控制信道(PSCCH,Physical Sidelink Control Channel)资源池,用于承载边链路控制信息;物理边链路共享信道(PSSCH,Physical Sidelink Shared Channel)资源池,用于承载边链路数据业务信息;物理边链路广播信道(PSBCH,Physical Sidelink Broadcast Channel)资源池,用于承载Sidelink广播信息;物理边链路发现信道(PSDCH,Physical Sidelink Discovery Channel)资源池,用于承载Sidelink发现信号;物理边链路反馈信道(PSFCH,Physical Sidelink Feedback Channel)资源池,用于承载边链路反馈信息。
Sidelink资源池也可以定义为包含上述任意一种或多种Sidelink信道资源的资源集合,例如,Sidelink resource pool中包含PSCCH,PSSCH和PSFCH资源,而不再称为PSCCH resource pool,PSSCH resource pool,PSFCH resource pool。两种方式都是定义Sidelink资源的方式,不影响本公开方案的本质。
通常,根据场景需求,网络侧会为Sidelink UE配置Sidelink资源池,或者由***预配置Sidelink资源池,UE使用Sidelink资源池中的资源承载Sidelink信息。网络侧配置或***预定义配置中,可以为Sidelink UE配置上述多种类型的Sidelink资源池中的任意一个或多个。其中,***可以是无线通信网络***,这里可以认为是由更高层级的节点确定,Sidelink资源池是预定义配置的资源集合。
当UE在Sidelink进行信息的交互时,发送端UE在PSCCH资源上发送Sidelink控制信息(SCI,Sidelink Control Information),向接收端UE指示所传输的Sidelink数据信息所使用的PSSCH资源,以及相关的控制信息,如调制编码方式(MCS,Modulation and Coding Scheme),功率控制指示,数据重传指示等。发送端UE在SCI所指示的PSSCH资源上发送Sidelink数据。另外,UE还可以在PSBCH资源上发送Sidelink广播信息,在PSDCH资源上发送Sidelink发现信息,在PSFCH资源上向发送端反馈所接收数据包的确认/非确认信息(Acknowledgement/Non-Acknowledgement,Ack/Nack)。
网络侧包括但不限于基站(next generation NodeB,gNB)、中继站(Relay Node,RN)、小区协作实体(Multicast Coordination Entity,MCE)、网关(Gateway,GW)、移动性管理设备(Mobility Management Entity,MME)、演进型通用陆地无线接入网(Evolved Universal Terrestrial Radio Access Network,EUTRAN)操作管理及维护(Operation And Maintenance,OAM)管理器等。
可选地,Sidelink资源池是用于承载Sidelink信息或信号的一组资源,由网 络侧通过物理层和/或高层信令配置,或者由***预配置。每个Sidelink资源池在时域上可以包含一个或多个时域资源单元,时域资源单元包括以下任意一项或多项:符号,slot,mini-slot;在频域上包含一个或多个RB,所包含的多个RB可以连续或不连续。其中,PSCCH资源池,PSSCH资源池,PSBCH资源池,PSDCH资源池都是Sidelink资源池的一种,本申请中对Sidelink资源池的配置指示方式可应用于上述任意一种或多种资源池配置。
当Sidelink资源池的资源共享蜂窝通信时域及频域资源时,需要以蜂窝链路中已有的时域和频域资源为基础进行配置。比如:以蜂窝链路已指示的符号及slot划分,符号的类型为基础,配置Sidelink资源池中的时域资源。
由于UE可以同时保持蜂窝通信与Sidelink通信,因此Sidelink资源池的配置需要尽量避免与蜂窝通信资源冲突,也就是说,Sidelink资源池中包含的时域和频域资源应尽可能不影响蜂窝链路的资源配置。在新一代通信***如5G***中,小区内进行蜂窝通信的UE可以通过接收网络侧节点(如基站)的相应配置信令确定时域上每个slot中的各个符号的符号类型。根据基站的调度指示,UE使用相应符号类型的符号接收或发送信号。
由于Sidelink通信的信号由UE发送,由周围其他支持Sidelink通信的UE接收,为了避免受到蜂窝下行信号的干扰,Sidelink资源池中应采用UL symbol和/或F symbol,而避免使用DL symbol。其中,这里所说的UL symbol或F symbol是指蜂窝通信中,基站为蜂窝链路所配置的UL symbol或F symbol。其中,当一个slot中的所有符号都配置为F symbol时,也可以称为F slot,为简便起见,下面说明中统称为F资源,F资源是指配置为F symbol的时域符号,或者F slot。另外,F资源是蜂窝通信(即基站与UE之间的Uu接口上)的资源配置中由基站指示为F symbol或F slot的时域资源,可以是由基站通过小区广播消息配置指示的F资源,或者由基站向UE发送的专用配置信息中指示出的F资源,专用配置信息包括UE专用RRC消息,或DCI指示。
由于NR***中F资源可以被配置指示为DL资源或UL资源,具有很强的灵活性,同一个slot或symbol对不同的UE可以有不同的配置。例如,slot#n中包含多个个F symbol,这些F symbol对于UE A可以被重配置为DL symbol,对UE B则可以被重配置为UL symbol。而当F资源配置为DL资源时不能作为Sidelink资源使用,此时如果配置协调不当,则可能导致蜂窝通信的配置与Sidelink资源配置冲突,本公开提出的方案即解决NR***中蜂窝通信配置的F资源配置为Sidelink资源的问题,从而达到避免资源配置冲突,提高资源利用率,有效实现蜂窝通信与Sidelink通信资源的共享。

边链路资源池周期指示边链路资源池配置的重复时间间隔,例如,当周期配置为40ms时,即所指示的Sidelink资源池中的时域资源配置以40ms为周期重复。
Sidelink时域资源配置可以指示周期内的时隙索引号(slot index),所指示出的slot即为Sidelink资源池中的资源。所指示的slot index是Sidelink资源池周期中包含的所有slot的顺序编号。
或者,Sidelink时域资源配置以位图(bitmap)的方式指示在Sidelink资源池周期内的时隙,bitmap序列的长度小于或等于周期值,bitmap中的每一bit对应于周期中的一个slot,当相应的bitmap指示位为“1”时,表示相应的slot为Sidelink资源池中的资源,当相应的bitmap指示位为“0”时,表示相应的slot不作为Sidelink资源池中的资源。当第二配置信息中指示了Sidelink时域资源配置在周期内的偏移(offset)时,从Sidelink资源池周期边界开始偏移offset值,开始bitmap序列的对应指示。

当第二配置信息中指示的偏移量offset为Sidelink资源池周期偏移量时,所指示的offset是指Sidelink资源池周期的起始位置相对于***帧号(System frame number,SFN)或直传链路帧号(Direct Frame Number,DFN)边界的偏移量。
当第二配置信息中指示的offset为Sidelink时域资源配置在周期内的偏移量时,所指示的offset是指第二配置信息中指示的Sidelink时域资源指示信息,如bitmap等,相对于Sidelink资源池周期的边界的相对偏移量。
当offset表示Sidelink时域资源配置在周期内的偏移量时,offset可以为预配置值或根据预定义规则隐式确定,不需要在第二配置信息明确指示,例如,offset值等于Sidelink资源池周期内的DL slot数量,或者offset等于Sidelink资源池周期内的DL slot数量与F slot数量之和,或者offset值根据第一配置信息确定,例如当第一配置信息指示为F资源不可用时,offset等于Sidelink资源池周期内的DL slot数量与F slot数量之和,当第一配置信息指示为F资源可用时,offset等于Sidelink资源池周期内的DL slot数量。
在同一边链路资源上可以配置多个sidelink资源池,上述sidelink资源池的配置指示对每个资源池独立。
通过以上的实施方式的描述,上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现,当然也可以通过硬件。本公开的技术方案可以以软件产品的形式体现出来,该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中,包括若干指令用以使得一台终端设备(可以是手机,计算机,服务器,或者网络设备等)执行本公开各个实施例所述的方法。

为了理解上述实施例中给出的技术方案,还提供了如下的场景以便理解:
场景一:
UE接收小区***广播消息,获得了基站配置的第一配置信息(也称为Type1第一配置信息)和第二配置信息,并确定Sidelink资源池中的时域资源配置。
图6是根据本公开实施例的一种基于场景一的资源配置图。如图6所示,UE接收到的第一配置信息中指示小区公共的F资源对Sidelink不可用(即不使能)。其中,小区公共的F资源由基站通过***广播消息指示,即UE通过蜂窝通信链路上配置指示的时域资源类型配置(时分双工(Time Division Duplex,TDD)-UL-DL-SlotConfig)中指示的DL,F,UL资源确定,其中指示了slot#7,slot#8,slot#9为F slot。第二配置信息中指示了Sidelink资源池周期为40ms,以每个slot长度为1ms为例,第二配置信息中指示了40bit的bitmap序列,用于指示Sidelink slots。
图7是根据本公开实施例的另一种基于场景一的资源配置图。如图7所示,在第二配置信息中指示出的Sidelink资源池中包含的多个slot中,slot#7,slot#8,slot#9为F slot,则根据第一配置信息的指示,F资源不能作为Sidelink资源,则实际的Sidelink资源池包含的时域资源中包含除F slot之外的所有bitmap序列对应bit为“1”的slot。
场景二
UE接收基站的专用RRC消息,其中,向UE指示了UE专用的第一配置信息(也称为Type 2第一配置信息)和第二配置信息,UE根据配置指示确定Sidelink资源池中的时域资源配置。这里,由于第一配置信息和第二配置信息是通过UE专用信令指示给UE的,UE根据相应指示确定的Sidelink资源池是UE专用Sidelink资源池,或者UE所属的Sidelink通信组的组专用Sidelink资源池。
图8是根据本公开实施例的一种基于场景二的资源配置图。如图8所示,UE接收到的第一配置信息中指示F资源对Sidelink可用(即使能),第二配置信息中指示了Sidelink资源池周期为40ms,以每个slot长度为1ms为例,第二配置信息中指示了Sidelink slot的相应的slot index为slot#1,slot#3,slot#5,...,slot#39。
图9是根据本公开实施例的另一种基于场景二的资源配置图。如图9所示, 基站配置的蜂窝通信资源结构为,slot#0至slot#4是DL slot,slot#31至slot#39为UL slot,其他为F slot。则UE根据第一配置信息与第二配置信息的指示,F资源作为Sidelink资源,UE可以确定实际Sidelink资源池中包含的slot有:slot#5,slot#7,slot#9,...,slot#37,slot#39。
场景三
图10是根据本公开实施例的一种基于场景三的资源配置图。如图10所示,UE接收小区***广播消息,获得了基站配置的第一配置信息和第二配置信息。其中,UE接收到的第一配置信息中指示小区公共(cell common)F资源对Sidelink可用,第二配置信息中指示了Sidelink资源池周期为10ms,以每个slot长度为1ms为例,第二配置信息中指示了10bit的bitmap序列,用于指示Sidelink slots,分别指示了slot#4,slot#5,slot#6为Sidelink slot,另外第二配置信息中还指示了每个Sidelink slot中的symbol#7至slot#13作为Sidelink资源。
图11是根据本公开实施例的另一种基于场景三的资源配置图。如图11所示,在第二配置信息中指示出的Sidelink资源池中包含的多个slot中,slot#4为DL slot,则UE根据配置指示,确定slot#4不是Sidelink资源池中的资源,slot#5中的所有符号为F symbol,则UE确定为slot#5中的symbol#7至symbol#13为Sidelink资源池中的资源,slot#6为UL slot,则UE确定slot#6为Sidelink资源。
场景四
图12是根据本公开实施例的一种基于场景四的资源配置图。如图12所示,UE接收小区***广播消息,获得了基站配置的第一配置信息和第二配置信息。其中,UE接收到的Type 1第一配置信息中指示cell common F资源对Sidelink不可用。另外,UE还接收基站的专用RRC消息,指示了UE专用的Type 2第一配置信息,其中,指示了第一节点专用配置信令中指示的F资源对Sidelink可用。如图12中上面的附图所示,UE根据基站对蜂窝通信资源的配置指示,确定cell common F资源的配置。slot#3,slot#4,slot#5,slot#6为F slot。如图12中下面的附图所示,基站通过RRC消息重配置后第一节点专用配置的F资源,slot#4,slot#5为F slot。且***定义的优先级规则为,当UE获得的多个类型的第一指示信息在相同的F资源上的配置指示不相同时,以Type 2第一配置信息的指示为准,即Type 1第一配置信息的指示无效,即slot#4,slot#5的F资源对此UE为Sidelink可用资源。
广播消息中指示的第二配置信息中,指示了Sidelink资源池周期为10ms,以每个slot长度为1ms为例,第二配置信息中指示了Sidelink资源池中包含slot#2,slot#3,slot#4,slot#5,slot#6,slot#7,slot#8。
图13是根据本公开实施例的另一种基于场景四的资源配置图。如图13中上面的附图所示,根据上述配置信息,slot#3,slot#4,slot#5,slot#6为cell common F资源,则UE根据广播消息指示的Type 1第一配置信息可以确定,相应slot不是Sidelink公共资源池中的资源,则Sidelink公共资源池中包含slot#7,slot#8。
如图13中下面的附图所示,slot#4,slot#5是UE专属配置指示的F slot,slot#6是UE专用配置指示出的UL slot,且UE专用配置中指示的Type 2第一配置信息指示为F资源可用,则slot#4,slot#5,slot#6为UE专用的Sidelink资源池中的资源,或者为UE所在Sidelink通信群组专用的Sidelink资源池中的资源。
场景五
图14是根据本公开实施例的一种基于场景五的资源配置图。如图14所示,第二配置信息中指示Sidelink资源池周期为10ms,且每个slot中用于Sidelink的symbol配置相同,为symbol#5至slot#11。以每个slot长度为1ms为例,第二配置信息中指示了10bit的bitmap序列“00111 11000”,用于指示Sidelink slots,则所指示出的Sidelink资源池中时域资源配置。
图15是根据本公开实施例的另一种基于场景五的资源配置图。如图15所示,另一实例为,第二配置信息中指示Sidelink资源池周期为40ms,以10ms为一组,同组内的slot中的Sidelink symbol配置相同,周期内分为4组。以slot长度为1ms为例,第二配置信息中指示了slot#1,slot#3,slot#5,...,slot#39为Sidelink slots,第一组中的Sidelink symbol配置为slot中的所有symbol,第二组中的Sidelink symbol配置为slot中的#7至#13,第三组中的Sidelink symbol配置为slot中的#4至#8,第四组中的Sidelink symbol配置为slot中的#11和#12,第二配置信息中指示出的Sidelink资源池中时域资源配置如图中所示。
场景六
在Sidelink通信的专用载波上,***预配置的公共的Sidelink资源配置的第一配置信息和第二配置信息。其中,第二配置信息指示Sidelink资源池中包含所有的时域资源,例如,以bitmap指示时,bitmap序列为全“1”序列。另外,专用载波上有预配置的时域资源类,例如,所有时域资源都是UL资源,或者为F和UL资源,F资源与UL资源的位置由***预配置。
UE工作在专用载波上时,通过预配置的第一配置信息和第二配置信息确定Sidelink资源池的资源。
当第一配置信息指示为F资源可用时,则根据第二配置信息的指示,专用 载波上的所有时域资源都是Sidelink资源池中的资源。当第一配置信息指示为F资源不可用时,则Sidelink资源包含所有UL资源。
场景七
UE与基站在蜂窝通信链路上的资源划分单位与UE在Sidelink上使用的资源划分单位可以不一致,即蜂窝通信上行链路的子载波间隔及slot长度,与Sidelink上的子载波间隔及slot长度不相同。此时,Sidelink资源池中包含的时域资源的指示需要按二者资源划分单位进行转换。
图16是根据本公开实施例的一种基于场景七的资源配置图。如图16所示,UE的蜂窝通信上行链路的slot长度为0.5ms,Sidelink资源的slot长度为1ms,UE从基站获得的第一配置信息指示为F资源可用,第二配置信息中指示的Sidelink资源池周期为10ms,对应的bitmap序列为“00011 00011”,每bit对应于Sidelink上的一个slot。
UE通过蜂窝通信链路上配置指示的时域资源类型配置中指示的DL,F,UL资源确定相应的时域资源类型,其中,蜂窝通信链路上的slot#14至slot#19为F slot,其他为DL slot。则UE根据上述预配置信息可以确定,Sidelink资源池中包含的时域资源为Sidelink slot#8,slot#9。
场景八
图17是根据本公开实施例的一种基于场景八的资源配置图,如图17所示,第二配置信息中指示了offset,且offset定义为Sidelink资源池周期相对于SFN或DFN边界的偏移量,则Sidelink资源池的周期根据offset的指示确定。第二配置信息指示offset=5ms,Sidelink资源池的周期=20ms,则Sidelink资源池的周期窗口如图所示。
图18是根据本公开实施例的另一种基于场景八的资源配置图,如图18所示,第二配置信息指示了offset,且offset定义为Sidelink时域资源配置在周期内的偏移量,则Sidelink资源池的时域指示根据offset的配置确定。以bitmap指示Sidelink资源池中包含的slot为例说明。如图18所示,Sidelink资源池周期为10ms,offset=4ms,slot长度为1ms,则相应的bitmap序列长度为6,从周期内的slot#4开始对应指示。
在另一实例中,offset为***预定义值,offset值等于蜂窝通信的资源配置中DL slot的数量,则UE根据蜂窝通信链路上的资源配置指示确定相应的offset值。
场景九
基站通过***广播消息配置指示多个Sidelink资源池,并分别为每个资源池 指示了相应的第二配置信息和第一配置信息。
图19是根据本公开实施例的一种基于场景九的资源配置图,如图19所示,如图19所示,基站配置了两个Sidelink资源池,其中,第二配置信息为公共配置,bitmap指示为“00000 01111”,第一个Sidelink资源池(上方的资源池)的第一配置信息指示为F资源不可用,第二个Sidelink资源池(下方的资源池)的第一配置信息指示为F资源可用,则UE可相应确定第一个Sidelink资源池包含slot#8,slot#9,第二个Sidelink资源池中包含slot#6至slot#9。
场景十
在Sidelink专用载波上,***预配置第一配置信息,即Type 0第一配置信息,配置为F资源可用。UE从基站获得Type 1第一配置信息,指示为F资源不可用。根据***预定义的第一配置信息的使用规则,当UE同时有Type 0和Type 1第一配置信息,二者的配置指示在相同的F资源上,以Type 1第一配置信息的指示为准,此时相应的Type 0第一配置信息的指示无效。
