具体实施方式
下面将结合附图,对本申请实施例中的技术方案进行描述。
应理解,本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile Communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division  Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、以及未来的5G通信系统等。
本申请结合终端设备描述了各个实施例。终端设备也可以指用户设备(User Equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的陆上公用移动通信网(Public Land Mobile Network,PLMN)网络中的终端设备等。
本申请结合网络设备描述了各个实施例。网络设备可以是用于与终端设备进行通信的设备,例如,可以是GSM系统或CDMA中的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络侧设备或未来演进的PLMN网络中的网络侧设备等。
图1和图2是本申请实施例可能的应用场景的示意图。图1示例性地示出了一个网络设备和两个终端设备,可选地,该无线通信系统可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备,本发明实施例对此不做限定。
此外,该无线通信系统还可以包括移动管理实体(Mobile Management Entity,MME)、服务网关(Serving Gateway,S-GW)、分组数据网络网关(Packet Data Network Gateway,P-GW)等其他网络实体,但本发明实施例不限于此。
终端设备20和终端设备30可以D2D通信模式进行通信,在进行D2D通信时,终端设备20和终端设备30通过D2D链路即侧行链路(Sidelink,SL)直接进行通信。例如图1或者图2所示,终端设备20和终端设备30通过侧行链路直接进行通信。在图1中,终端设备20和终端设备30之间通过侧行链路通信,其传输资源是由网络设备分配的;在图2中,终端设备20和终端设备30之间通过侧行链路通信,其传输资源是由终端设备自主选取的,不需要网络设备分配传输资源。
D2D通信可以指车对车(Vehicle to Vehicle,简称“V2V”)通信或车辆到其他设备(Vehicle to Everything,V2X)通信。在V2X通信中,X可以泛指任何具有无线接收和发送能力的设备,例如但不限于慢速移动的无线装置,快速移动的车载设备,或是具有无线发射接收能力的网络控制节点等。应理解,本发明实施例主要应用于V2X通信的场景,但也可以应用于任意其它D2D通信场景,本发明实施例对此不做任何限定。
车联网中定义了两种传输模式,即传输模式3(mode 3)和传输模式4(mode 4)。模式3(简称为模式3)的终端设备的传输资源是由基站分配的,终端设备根据基站分配的资源在侧行链路上进行数据的发送;基站可以为终端设备分配单次传输的资源,也可以为终端设备分配半静态传输的资源。传输模式4(简称为模式4)的终端设备如果具备侦听能力,采用侦听(sensing)和预留(reservation)的方式传输数据,如果不具备侦听能力,则在资源池中随机选取传输资源。具备侦听能力的终端设备在资源池中通过侦听的方式获取可用的资源集合,终端设备从该集合中随机选取一个资源进行数据传输。由于车联网系统中的业务具有周期性特征,因此终端设备通常采用半静态传输的方式,即终端设备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。终端设备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,从而使得其他终端设备可以通过检测该终端设备的控制信息判断这块资源是否被该终端设备预留和使用,达到降低资源冲突的目的。
终端设备在数据传输过程中使用的上述各个资源池都是预先配置的或者网络配置的。当终端设备处于网络覆盖范围外的时候,只能使用预配置的资源池与其他终端设备进行数据传输。当终端设备处于网络覆盖范围内时,可以使用预配置的资源池与网络覆盖外的终端设备进行数据传输,也可以使用网络配置的资源池与网络覆盖内的其他终端设备进行数据传输。但是在NR中,对终端设备之间的数 据传输性能提出了更高的要求,例如期望更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配方式等。因此,除了预配置的这些资源池外,网络设备还可以为终端设备配置额外的资源池用于网络覆盖范围内的用户与网络覆盖范围外的终端设备进行数据传输。
本申请实施例提出,第一终端设备通过发送第一侧行传输信道以指示资源池的资源池配置信息,使得第二终端设备能够接收指示该资源池配置信息的第一侧行传输信道,并获取该资源池的资源池配置信息,从而能够使用该资源池与第一终端设备进行通信。该资源池可以是除了预配置的资源池之外的其他额外的资源池,由于配置了额外的资源池,且第一终端设备可以将该额外的资源池的资源配置信息通知给其他的终端设备,更多的终端设备能够获得该资源池的信息并使用该资源池进行通信,因此一定程度上提高终端设备之间的数据传输性能。
图3是本申请一个实施例的资源配置的方法的流程交互图。图3所示的方法可以由第一终端设备和第二终端设备执行,该第一终端设备例如可以为图2中所示的终端设备20或终端设备30,该第二终端设备例如可以为图2中所示的终端设备30或终端设备20。
如图3所示,该资源配置的方法包括:
在310中,第一终端设备发送第一侧行传输信道。
在320中,第二终端设备接收该第一侧行传输信道。
其中,该第一侧行传输信道用于指示目标资源池的资源池配置信息,该目标资源池用于该第一终端设备与该第二终端设备之间进行通信。
该目标资源池例如可以是上述的网络设备为终端设备配置的用于进行通信的额外的资源池。或者说,该目标资源池是除了预先配置的用于终端设备进行D2D通信的资源池之外的资源池。
可选地,该第一终端设备可以为小区内的终端设备,该第二终端设备可以为该小区之外的终端设备。这里,第二终端设备可以位于该第一终端设备所在小区之外且不属于其他小区,或者,第二终端设备可以位于其他小区即第二终端设备和第一终端设备所在的小区不同。
当该第一终端设备为小区内的终端设备时,第一终端设备可以从网络设备接收该目标资源池的资源池配置信息,从而在该目标资源池中进行数据传输。但是,如果该小区之外存在第二终端设备,那么由于该第二终端设备无法接收网络设备发送的该资源池配置信息,该第二终端设备则无法使用目标资源池进行数据传输。这时,根据本申请实施例的方法,第一终端设备可以向第二终端设备发送第一侧行传输信道,以指示该目标资源池的资源池配置信息,以使第二终端设备能够获知该目标资源池的存在,从而在进行数据传输时可以使用该目标资源池。
在一种实现方式中,该第一侧行传输信道可以为物理侧行链路广播信道(Physical Sidelink broadcast Channel,PSBCH)。该PSBCH中直接携带目标资源池的资源池配置信息。
在另一种实现方式中,该第一侧行传输信道可以为物理侧行链路控制信道(Physical Sidelink Control Channel,PSCCH),该PSCCH调度的物理侧行链路共享信道(Physical Sidelink Shared Channel,PSSCH)中携带该资源池配置信息,例如图4(a)所示;或者,该第一侧行传输信道可以为PSSCH,该PSSCH中携带该资源池配置信息,例如图4(b)所示。
本申请实施例中的第一侧行传输信道既可以为协议中已有的传输信道例如为上述的PSCCH、PSSCH、或者PSBCH等,也可以为新增加的用于传输资源配置信息的传输信道,本申请实施例对该第一侧行传输信道的格式不做任何限定。
可选地,在310之前,该方法还包括:第一终端设备确定第一传输资源。此时,在310中,第一终端设备发送第一侧行传输信道,包括:第一终端设备在该第一传输资源上发送该第一侧行传输信道。
相应地,该方法还包括:第二终端设备确定第一传输资源。此时,在520中,该第二终端设备接收第一侧行传输信道,包括:该第二终端设备在该第一传输资源上接收该第一侧行传输信道。
也就是说,第一终端设备并不是在任意的资源上发送该第一传输信道,而是在第一传输资源上发送该第一传输信道。例如,该第一传输资源仅用于传输该资源池配置信息,而不用于传输其他侧行数据。并且,可选地,该第一传输资源可以是预配置或者网络设备配置的传输资源,或者可以是预配置或者网络设备配置的接收资源池中的一个传输资源。
进一步地,可选地,第一终端设备确定第一传输资源,包括:第一终端设备在K个候选资源中,选择一个或多个资源作为该第一传输资源,K为正整数。
或者,可选地,第一终端设备确定第一传输资源,包括:第一终端设备根据预存在该第一终端设备中的该第一传输资源的信息,确定该第一传输资源。
或者,可选地,该方法还包括:第一终端设备接收网络设备发送的第一指示信息,该第一指示信息用于指示该第一传输资源;其中,该第一终端设备确定第一传输资源,包括:第一终端设备根据该第一指示信息,确定该第一传输资源。
该第一传输资源可以是终端设备在预配置的K个候选资源中选择的一个或多个资源,例如可以是随机选择;或者,该第一传输资源可以是预存在终端设备中的,例如协议中事先约定的;或者,该第一传输资源可以是网络设备为终端设备配置的。
第一终端设备在确定第一传输资源后,会在第一传输资源上发送该第一侧行传输信道,该侧行传输信道指示了目标资源池的资源池配置信息。但为了使其他终端设备能够获知该第一传输资源的位置以便在该第一传输资源上接收该第一侧行传输信道,可选地,该方法还包括:第一终端设备发送第二侧行传输信道,该第二侧行传输信道携带资源指示信息,该资源指示信息用于指示该第一传输资源。
相应地,可选地,该方法还包括:第二终端设备接收第二侧行传输信道,该第二侧行传输信道携带资源指示信息,该资源指示信息用于指示该第一传输资源。其中,第二终端设备确定第一传输资源,包括:第二终端设备根据该第二侧行传输信道,确定该第一传输资源。
因此,终端设备通过第二侧行传输信道向其他终端设备指示第一传输资源,从而使得其他终端设备能够在该第一传输资源上接收该第一侧行传输信道,并获取该目标资源池的资源池配置信息。
当然,该第二终端设备也可以根据预存在该第二终端设备中的该第一传输资源的信息,确定该第一传输资源。即该第一传输资源可以是预存在终端设备中的,例如协议中事先约定的。
下面结合情况1至情况4,详细描述该第二侧行传输信道中携带的资源指示信息所包括的内容。该第二侧行传输信道例如可以是PSBCH。

例如,可以预配置多个第一传输资源(例如配置多个传输资源中每个传输资源的时频位置、所占的时域资源大小、所占的频域资源大小等信息),每个第一传输资源具有各自唯一的索引。第一终端设备发送的该资源指示信息可以包括用于传输第一侧行传输信道的该第一传输资源的索引。第二终端设备接收到该资源指示信息后,可以根据该第一传输资源的索引,在该多个第一传输资源中选择该索引所指示的第一传输资源用来接收第一侧行传输信道,从而获得目标资源池的资源池配置信息。预配置的该多个第一传输资源可以具有相同或者不同的时域资源大小和/或频域资源大小。
情况2
该资源指示信息包括该第一传输资源所在的第一资源池的信息,以及该第一传输资源在该第一资源池中的位置信息。
可选地,该资源指示信息还可以包括该第一传输资源的资源大小的信息。或者,当该资源指示信息不包括该第一传输资源的大小的信息时,可以通过预配置或者网络设备配置的方式确定该第一传输资源的大小,即该第一传输资源的大小为预配置或者网络设备配置的。
例如,该资源指示信息可以包括预配置的多个资源池中该第一传输资源所在的第一资源池的信息,例如包括该第一资源池的时频位置或索引等信息,从而可以根据该资源指示信息确定该第一传输资源所在的资源池。并且,该资源指示信息还包括第一传输资源在该第一资源池中的位置信息,例如包括该第一传输资源在该第一资源池中的时频位置或索引等信息。进一步地,该资源指示信息还可以包括第一传输资源的大小的信息。

该资源指示信息包括该第一传输资源所在的第一资源池的信息。其中,该第一传输资源为该第一资源池中位于特定时频位置的资源。
第一终端设备可以根据该第一资源池的信息、以及预配置的或者网络设备配置的该特定时频位置的信息,确定该第一传输资源在该第一资源池中所占的时频位置。
例如,该特定时频位置可以是,该第一传输资源为该第一资源池中位于该第二侧行传输信道之后的第M个子帧中的从最低或最高频域位置开始的第一个传输资源,M为正整数。优选地,M=1。例如图5所示,该第一传输资源位于该第一资源池中的第二侧行传输信道之后的第一个子帧中,且占用该子帧中的频域位置最低的一个子带即子带2。
可选地,该资源指示信息还可以包括该第一传输资源的资源大小的信息。或者,当该资源指示信息不包括该第一传输资源的大小的信息时,可以通过预配置或者网络设备配置的方式确定该第一传输资源的大小,即该第一传输资源的大小为预配置或者网络设备配置的。

应理解,该资源指示信息可以包括情况1至情况4中任意一个情况中所描述的信息,或者也可以同时包括情况1至情况4中所描述的各种信息中的全部或者部分。即上述情况1至情况4可以单独执行或者结合在一起执行。
还应理解,本申请实施例中,时域单元可以包括子帧、时隙、符号等,频域单元可以包括子带、资源块组(Resource Block Group,RBG)、PRB等。其中,一个子带包括连续的多个PRB,一个RBG包括连续的多个PRB。
可选地,本申请实施例中的目标资源池的资源池配置信息可以包括以下信息中的至少一种:

该目标资源池的索引。
下面详细描述该资源池配置信息所携带的该目标资源池的相关信息。
在NR-V2X中,可以支持多个载波。在小区内,网络设备可以配置各个载波上的资源池信息。在小区外,可以预配置一部分载波上的资源池信息。因此,小区内的终端设备发送的资源池配置信息可以包括载波信息,以用于指示该目标资源池是在位于哪个载波的。可选地,该目标资源池所在的载波的信息可以包括该目标资源池所在的载波的编号。并且,可选地,在第一载波上发送的资源池配置信息可以用于指示第二载波上的资源池。
可选地,如果在一个载波上可以配置多个带宽部分(Bandwidth Part,BWP),该资源池配置信息还可以包括BWP索引,以用于指示该目标资源池是位于哪个BWP的。

该目标资源池中的时域单元的数量,例如目标资源池中包括的子帧数量;
每个该控制信道资源所占的时域资源大小(比如所占的时域符号的数量),例如目标资源池中的每个控制信道资源在一个时域单元中所占的时域符号的数量;
每个该数据信道资源所占的时域资源大小(比如所占的时域符号的数量),例如目标资源池中的每个数据信道资源在一个时域单元中所占的时域符号的数量;
该目标资源池中的第一个传输资源的时域位置、该目标资源池中的最后一个传输资源的时域位置、以及该目标资源池的时域长度中的至少两个信息,例如,当目标资源池包括连续的时域资源时,该目标资源池所占的时域资源的信息可以包括目标资源池中的第一个传输资源的时域位置和该目标资源池的时域长度。
可选地,该目标资源池所占的时域资源的信息还可以包括该目标资源池所占的时域单元的信息,例如该目标资源池包括哪些时域单元。此时,可选地,该目标资源池所占的时域单元的信息可以通过比特图来表示,该比特图中的每个比特位上的值表示与该比特位对应的时域单元是否属于该目标资源池。
例如,该比特图中包括10个比特位,10个比特位中的每个比特位对应一个子帧或时隙。其中,比特位上的值为1时表示该比特位对应的子帧或时隙属于该目标资源池,比特位上的值为0时表示该比特位对应的子帧或时隙不属于该目标资源池。
可选地,该比特图可以用于指示每个固定时长范围内的子帧或时隙是否属于该目标资源池。例如,该固定时长为一个无线帧,每个无线帧包括10个子帧,该比特图中的10个比特位分别与每个无线帧中的10个子帧一一对应,该比特图中的每个比特位上的值用于表示与该比特位对应的子帧是否属于该目标资源池。一个无线帧周期中包括1024个无线帧,其中每个无线帧内属于该目标资源池的子帧都可以通过该比特图确定,即每个无线帧内属于该目标资源池的那些子帧的位置是相同的。例如,该比特位图为1111110000,表示一个无线帧周期中的每个无线帧内的第1个至第6个子帧都属于该目标资源池。
又例如,该比特图中包括14个比特位,该14个比特位可以分别表示子帧1中的14个时域符号是否属于该目标资源池,其中比特位上的值为1时表示该比特位对应的时域符号属于该目标资源池,比特位上的值为0时表示该比特位对应的时域符号不属于该目标资源池。该比特图为10101010101010时,表示目标资源池包括该子帧1内的符号0、符号2、符号4、符号6、符号8、符号10和符号12。
可选地,该目标资源池所占的时域资源的信息可以包括多个比特图。例如,该目标资源池所占的时域资源的信息包括第一比特图和第二比特图。其中,该第一比特图包括14个比特位,分别与每个子帧中的14个时域符号一一对应,用于表示每个子帧中哪些时域符号属于该目标资源池。该第二比特图包括10个比特位,分别与每个无线帧内的10个子帧一一对应,用于表示每个无线帧内的哪些子帧属于该目标资源池。因此,通过第二比特图,可以确定一个无线帧周期中的每个无线帧内的哪些子帧属于该目标资源池,通过第一比特图,又可以进一步确定这些子帧中的每个子帧内的哪些时域符号属于该目标资源池。
可选地,该目标资源池所占的频域资源的信息可以包括:
该目标资源池中的频域单元的大小,例如每个子带中的PRB数量;
该目标资源池中的频域单元的数量,例如目标资源池中包括的子带数量;
每个该控制信道资源所占的频域资源大小(比如所占的PRB或者子带的数量),例如目标资源池中的每个控制信道资源在一个频域单元中所占的PRB数量;
每个该数据信道资源所占的频域资源大小(比如所占的PRB或者子带的数量),例如目标资源池中的每个数据信道资源在一个频域单元中所占的PRB数量;
该目标资源池的频域起始位置、该目标资源池的频域终止位置、以及该目标资源池所占的频域大小中的至少两个信息,当目标资源池包括连续的频域资源时,该目标资源池所占的频域资源的信息可以包括目标资源池中的第一个传输资源的频域位置和该目标资源池的频域宽度。
例如,该目标资源池的频域起始位置是该目标资源池中第一个子带的索引,该目标资源池的频域终止位置是该目标资源池中最后一个子带的索引,该目标资源池所占的频域大小是该目标资源池中包括的子带数量。
可选地,该目标资源池中的控制信道资源和数据信道资源之间的位置关系(或者也可以称为该目标资源池的结构),包括该控制信道资源与该数据信道资源之间时分复用或者频分复用。
进一步地,目标资源池的资源池配置信息中可以包括该位置关系的索引,例如,当包括索引1时,指示控制信道资源与该数据信道资源之间时分复用,当包括索引2时,指示控制信道资源与该数据信道资源之间频分复用。
在车联网系统中,终端设备进行数据传输时,数据传输和相应的资源调度信息的传输可以采用频分复用(Frequency Division Multiplexing,FDM)或者时分复用(Time Division Multiplexing,TDM)的方式。
具体地,采用频分复用的方式时,用于传输资源调度信息的资源池与用于传输数据的资源池有两种配置方式,即频域相邻(adjacent)和非相邻(non-adjacent)的方式。
例如图6所示的频域相邻(adjacent)的情况,用于传输资源调度信息的控制信道资源,与该控制信道对应的数据信道资源在频域上是相邻的。整个系统带宽以子频带(子带)为粒度,每个子带包括多个连续的PRB,每个子带中的第一个PRB和第二个PRB为可以用来传输控制信道,其余的PRB为可以用来传输数据信道。数据信道资源与控制信道资源之间的是一一对应的,控制信道资源上传输的资源调度信息用于调度该控制信道资源对应的数据信道资源上的数据传输,并且该数据信道资源的起始位置由其对应的控制信道资源的位置决定。数据信道资源可以占用一个子带(例如,子帧2上的数据信道资源位于子带1内),也可以跨过多个子带(例如,子帧4上的数据信道资源位于子带2和子带3内)。当数据信道资源占用多个子带时,数据信道资源在多个子带内是频域连续的,并可以占用其他子带内的控制信道资源,并且该数据信道资源对应的控制信道资源为该数据信道资源所在的第一个子带中的控制信道资源,例如,图6中的子帧4上的数据信道资源占用两个相邻的子带(子带2和子带3),其对应的控制信道资源为其中的第一个子带(子带2)内的控制信道资源。
例如图7所示的频域非相邻(non-adjacent)的情况,控制信道资源和其对应的数据信道资源在频域上是不相邻的,数据信道资源和控制信道资源是独立配置的,但是数据信道资源的位置和控制信道资源的位置仍是一一对应的,控制信道资源上传输的资源调度信息用于调度该控制信道资源对应的数据信道资源上的数据传输,并且该数据信道资源的起始位置可由其对应的该控制信道资源的位置决定。数据信道资源可以占用一个子带(例如,子帧2上示出数据信道资源位于子带1),也可以占用多个控制信道资源为该数据信道资源所在的第一个子带中的控制信道资源,例如,图7中的子帧4上的数据信道资源位于两个相邻的子带(子带2和子带3),其对应的控制信道资源为第一个子带(子带2)内的控制信道资源。
当采用时分复用的方式时,例如图8所示,第一终端设备在子帧1的子带3上发送自己的控制信道资源即PSCCH,该控制信道资源对应的数据信道资源即PSSCH在子帧4的子带2上传输,该控制信道资源上承载的侧行链路控制信息(Sindlink Control Information,SCI)中可以携带其对应的数据信道资源的信息;第二终端设备在子帧1的子带4上发送自己的控制信道资源,该控制信道资源对应的 数据信道资源在子帧5的子带3上传输,该控制信道资源上承载的SCI可以携带其对应的数据信道资源的信息;第三终端设备在子帧2的子带3上发送自己的控制信道资源,该控制信道资源对应的数据信道资源在子帧6的子带2上传输,该控制信道资源上承载的SCI可以携带其对应的数据信道资源的信息。
该目标资源池的资源池配置信息中可以携带该目标资源池中的控制信道资源和数据信道资源之间的该位置关系,第二终端设备接收该资源池配置信息后,就可以知道在该目标资源池中是按照图6或图7所示的方式,还是按照图8所示的方式传输控制信道和其对应的数据信道。
进一步地,当确定目标资源池的控制信道资源和数据信道资源的位置关系后,该资源池配置信息中还可以包括:该控制信道资源和该数据信道资源的频域资源相邻或者不相邻的信息,和/或,该控制信道资源和该数据信道资源的时域资源相邻或者不相邻的信息。
例如,当确定采用频分复用的方式时,该资源池配置信息中包括该控制信道资源和该数据信道资源的频域资源相邻或者不相邻的信息。
可选地,该目标资源池的解调参考信号(De Modulation Reference Signal,DMRS)图样的信息,包括该目标资源池的DMRS图样的索引。
例如,可以预配置多种DMRS图样,并且每个DMRS图样具有自己唯一的索引。该资源池配置信息中可以携带在该目标资源池中进行D2D通信时所使用的DMRS图样的索引。
由于NR中可以支持不同的基本参数集,例如,在低频段(例如小于6GHz)的情况下,可以采用15k、30kHz的子载波间隔;在高频段(例如大于6GHz)的情况下,可以采用60k、120kHz的子载波间隔。因此,目标资源池的资源池配置信息中也需要携带基础参数集的信息。
可选地,该基本参数集可以包括以下参数中的至少一种:子载波间隔、特定带宽下的子载波数目、物理资源块PRB中的子载波数、正交频分复用OFDM符号的长度、用于生成OFDM信号的傅里叶变换例如快速傅里叶变换(Fast Fourier Transform,简称“FFT”)或傅里叶逆变换例如快速逆傅里叶变换(Inverse Fast Fourier Transform,简称“IFFT”)的点数、传输时间间隔TTI中的OFDM符号数、特定时间长度内包含的TTI的个数和信号前缀的长度。
其中,子载波间隔可以指相邻子载波的频率间隔,例如15kHz,60kHz等;特定带宽下的子载波数目例如为每个可能的系统带宽对应的子载波数;PRB中包含的子载波数例如典型的可以是12的整数倍;TTI中包含的OFDM符号数例如典型的可以是14的整数倍;一定时间单位内包含的TTI数可以指1ms或者10ms的时间长度内包含的TTI数目;信号前缀长度例如为信号的循环前缀的时间长度,或者循环前缀使用常规(Cyclic Prefix,CP)还是使用扩展CP。
考虑到每个载波上可以配置多个资源池,因此,更方便地,目标资源池的资源池配置信息中还可以携带该目标资源池的索引。例如,可以预配置多个候选的资源池(例如预配置多个候选资源池中每个候选资源池的上述资源配置信息),每个候选资源池具有各自唯一的索引,根据该第一侧行传输信道上承载的该资源配置信息中携带的索引,就可以获得该目标资源池的上述资源配置信息。
