值得指出的是,本申请实施例所描述的技术不限于长期演进型(Long Term Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)***,还可用于其他无线通信***,诸如码分多址(Code Division Multiple Access,CDMA)、时分多址(Time Division Multiple Access,TDMA)、频分多址(Frequency Division Multiple Access,FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access,SC-FDMA)和其他***。本申请实施例中的术语“***”和“网络”常被可互换地使用,所描述的技术既可用于以上提及的***和无线电技术,也可用于其他***和无线电技术。以下描述出于示例目的描述了新空口(New Radio,NR)***,并且在以下大部分描述中使用NR术语,但是这些技术也可应用于NR***应用以外的应用,如第6代(6
th Generation,6G)通信***。
图1示出本申请实施例可应用的一种无线通信***的框图。无线通信***包括终端11和网络侧设备12。其中,终端11也可以称作终端设备或者用户设备(User Equipment,UE),终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计 算机(Ultra-Mobile Personal Computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备(Vehicle User Equipment,VUE)、行人终端(Pedestrian User Equipment,PUE)等终端侧设备,可穿戴式设备包括:智能手表、手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网,其中,基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、无线局域网(Wireless Local Area Network,WLAN)接入点、WiFi节点、发送接收点(Transmitting Receiving Point,TRP)或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR***中的基站为例,但是并不限定基站的具体类型。
为了便于理解本申请实施例,首先说明以下内容。
请参见图2,图2示出本申请实施例中一个IAB***的示意图。在IAB***中,一个IAB节点包括分布单元(Distributed Unit,DU)功能部分和移动终端(Mobile Termination,MT)功能部分,依靠MT功能部分,该IAB节点可以找到一个父IAB节点(parent IAB node),并与父IAB节点的DU建立无线连接,该无线连接被称为回传链路(backhaul link)。在一个IAB节点建立完整的回传链路后,该IAB节点可以打开其DU功能,DU会提供小区服务,即DU可以为用户设备(User Equipment,UE)提供接入服务。一个自回传回路包含一个施主donor IAB节点(或者称为IAB donor),donor IAB节点有直接相连的有线传输网。
本申请实施例中,IAB***的引入是为了解决接入点密集部署时,有线传输网部署不到位的情况,即在没有有线传输网络时,接入点可以依赖无线回传。
可选地,IAB节点之间的无线链路可称为回传(Backhaul,BH)链路link。 BH link上可以配置有BH无线链路控制(Radio Link Control,RLC)信道进行无线回传。
本申请实施例中,回传自适应协议(Backhaul adaptation protocol,BAP)控制control协议数据单元(Protocol Data Unit,PDU)用来承载BAP层的控制信息。其中,一种已定义的BAP control PDU类型为:BH RLF indication。该BH RLF indication也可称为类型4(type-4)BH RLF indication。该BH RLF indication可由BAP control PDU承载,一个IAB节点可以利用BAP control PDU通知其子IAB节点该IAB节点与其父IAB节点之间无线链路恢复失败的消息。
例如,假设IAB网络拓扑结构为:
IAB节点1->IAB节点2->IAB节点3->IAB-donor-DU->IAB-donor-CU
其中,CU表示集中单元(Central Unit),若IAB节点2与其父节点IAB节点3之间的链路发生了RLF,且进行RLF恢复(recovery)失败了,则IAB节点2可以向其子节点IAB节点1发送BH RLF indication,用于告知IAB节点2与IAB节点3之间的链路出现问题。
此外,还存在两种BAP control PDU类型:
1)type-2 BH RLF indication:一个IAB节点在与其父IAB节点的无线链路发生失败,可以通过type-2 BH RLF indication向子IAB节点通知RLF;
2)type-3 BH RLF indication:一个IAB节点在与其父IAB节点的无线链路失败后,但无线链路恢复成功,可以通过type-3 BH RLF indication向子IAB节点通知RLF恢复成功。
可选地,本申请实施例中所描述的“去激活态”,也可以称为待处理(pending)态或暂停态。
可选地,本申请实施例中的回传链路恢复正常的指示可以包括以下至少一项:类型3回传RLF indication、IAB节点的高层(如RRC层、RLC层)发送给媒体接入控制(Medium Access Control,MAC)层的回传链路恢复正常的指示。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的上行传输的控制方法进行详细地说明。
请参见图3,图3是本申请实施例提供的一种上行传输的控制方法的流程图,该方法由IAB节点执行,该IAB节点为终端,如图3所示,该方法包括以下步骤:
步骤31:IAB节点接收回传RLF indication。
可选地,IAB节点接收的回传RLF indication可以由回传适配协议(Backhaul Adaptation Protocol,BAP)control PDU承载。该回传RLF indication可以包括以下任意一项:类型2(type-2)回传RLF indication、类型4(type-4)回传RLF indication。即,IAB节点接收的回传RLF indication可以是type-2回传RLF indication,也可以是type-4回传RLF indication。
步骤32:IAB节点取消或者暂停已触发的数据发送。
可选地,上述已触发的数据发送可以称为已触发的上行数据发送。上述已触发的数据发送可以包括以下至少一项:已触发的调度请求(Scheduling Request,SR)、已触发的缓冲状态报告(Buffer Status Report,BSR)、已触发的抢先缓冲状态报告(Pre-emptive Buffer Status Report,PBSR)等。
本申请实施例的上行传输的控制方法,IAB节点在接收到回传RLF indication之后,可以取消或者暂停已触发的数据发送,从而实现对已触发的数据发送的处理,保证IAB网络中数据传输的稳定性。
下面分别以SR、BSR和PBSR为例,对本申请进行详细说明。
(1)基于回传RLF indication处理触发的SR
本申请实施例中,回传RLF indication比如为type-2/type-4回传RLF indication,可以用于取消或者暂停已触发的SR。
可选地,当IAB节点在与其父IAB节点间的回传链路上接收到回传RLF indication时,该IAB节点可以取消或者暂停第一SR;其中,第一SR是由于要发送给父IAB节点的BSR而触发的待处理SR。上述暂停第一SR可理解为去激活第一SR。
进一步的,在取消或者暂停第一SR时,当第一SR对应的第一定时器在运行时,IAB节点可以停止运行第一定时器。该第一定时器比如为sr-ProhibitTimer。
进一步的,在暂停第一SR之后,当接收到回传链路恢复正常的指示时,IAB节点可以恢复暂停的第一SR。
进一步的,在暂停第一SR,且停止运行第一定时器之后,当接收到回传链路恢复正常的指示时,IAB节点可以重新启动第一定时器,并将第一定时器的值设置为第一定时器被暂停时所对应的剩余时间值,或者,将第一定时器的值设置为计时器初始值。其中,该计时器初始值可以协议约定或者网络侧设备配置等,对此不进行限制。
比如,假设第一定时器sr-ProhibitTimer总共是64ms,停止运行前倒计时到30ms,则停止之后恢复具有2种情况:1)将sr-ProhibitTimer的值设置为64ms,重新从64ms倒计时;2)将sr-ProhibitTimer的值设置为30ms,从停止时的30ms倒计时。
可选地,当IAB节点的MAC实体没有为第一SR配置的有效上行资源时,第一SR在IAB节点接收到回传链路恢复正常的指示之前,不会触发随机接入(Random Access,RACH)过程。比如,该上行资源可以为物理上行控制信道(Physical Uplink Control Channel,PUCCH)资源。
可选地,当触发要发送给父IAB节点的BSR的待发送数据中包括RLC control PDU时,该RLC control PDU比如包括RLC状态报告,第一SR不会被取消或者暂停,即不取消或者暂停第一SR,以保证RLC状态报告的发送。
比如,如果IAB节点在与其父IAB节点间的回传链路上接收到type-2回传RLF indication,可以对于由于要发送给父IAB节点的BSR而触发的所有待处理SR(pending SRs)全部取消,并且每一个SR各自对应的计时器sr-ProhibitTimer需要被停止(如果计时器在运行的话)。
又比如,如果IAB节点在与其父IAB节点间的回传链路上接收到type-2回传RLF indication,则对于由于要发送给父IAB节点的BSR而触发的pending SRs,暂停/去激活对该pending SRs的后续处理,即直接表明停止处理该pending SRs的操作,并且每一个SR各自对应的计时器sr-ProhibitTimer需要被停止(如果计时器在运行的话)。
又比如,如果IAB节点在与其父IAB节点间的回传链路上接收到type-2回传RLF indication,则对于由于要发送给父IAB节点的BSR而触发的pending SRs,仍然遵循传统legacy的流程,即等待被处理,间接表明去激活/停止处理该pending SRs的操作。并且,该pending SRs在IAB节点接收到回传链路恢复正常的指示之前,不会触发RACH过程。也就是说,如果IAB节点在与其父IAB节点间的回传链路上接收到type-2回传RLF indication,则对于由于要发送给父IAB节点的BSR而触发的pending SRs,在接收到来自高层的回传链路恢复正常的指示之前,不会触发RACH过程。其中,在接收到来自高层的回传链路恢复正常的指示之前,触发type-2回传RLF indication的回传链路没有恢复正常,即如果接收到来自高层的回传链路恢复正常的指示,表明触发type-2回传RLF indication的回传链路恢复正常。
又比如,在暂停/去激活pending SRs之后,如果IAB节点接收到高层的回传链路恢复正常的指示,即指示“之前接收到type-2回传RLF indication的回传链路已经恢复正常”,则可以重新恢复对之前暂停/去激活pending SRs的操作,即恢复之前由于收到type-2回传RLF indication而停止操作的pending SRs。并且如果pending SRs之前触发了定时器,则重新开启该定时器,并且将该定时器的值设置成暂停/去激活时该计时器所对应的剩余时间,或者设置成计时器初始值。
可选地,当IAB节点在与其父IAB节点间的回传链路上接收到回传RLF indication时,该IAB节点可以取消或者暂停第二SR;其中,第二SR不是由于要发送给父IAB节点的BSR而触发的待处理SR。该暂停第二SR也可以称为去激活第二SR。
进一步的,在取消或者暂停第二SR时,当第二SR对应的第二定时器在运行时,IAB节点可以停止运行第二定时器。该第二定时器比如为 sr-ProhibitTimer。
进一步的,在暂停第二SR之后,当接收到回传链路恢复正常的指示时,IAB节点可以恢复暂停的第二SR。
进一步的,在暂停第二SR,且停止运行第二定时器之后,当接收到回传链路恢复正常的指示时,IAB节点可以重新启动第二定时器,并将第二定时器的值设置为第二定时器被暂停时所对应的剩余时间值,或者,将第二定时器的值设置为计时器初始值。其中,该计时器初始值可以协议约定或者网络侧设备配置等,对此不进行限制。
比如,假设第二定时器sr-ProhibitTimer总共是32ms,停止运行前倒计时到20ms,则停止之后恢复具有2种情况:1)将sr-ProhibitTimer的值设置为32ms,重新从32ms倒计时;2)将sr-ProhibitTimer的值设置为20ms,从停止时的20ms倒计时。
比如,如果IAB节点在与其父IAB节点间的回传链路上接收到type-2回传RLF indication,可以对于那些不是由于要发送给父IAB节点的BSR而触发的pending SRs全部取消,并且每一个SR各自对应的计时器sr-ProhibitTimer需要被停止(如果计时器在运行的话)。
又比如,如果IAB节点在与其父IAB节点间的回传链路上接收到type-2回传RLF indication,则对于那些不是由于要发送给父IAB节点的BSR而触发的pending SRs,在接收到回传链路恢复正常的指示之前,暂停/去激活对该pending SRs的后续处理,并且每一个SR各自对应的计时器sr-ProhibitTimer需要被停止(如果计时器在运行的话)。
又比如,在暂停/去激活pending SRs之后,如果IAB节点接收到高层的回传链路恢复正常的指示,即指示“之前接收到type-2回传RLF indication的回传链路已经恢复正常”,则可以重新恢复对之前暂停/去激活pending SRs的操作,即恢复对那些之前由于收到type-2回传RLF indication而停止操作的pending SRs。并且如果pending SRs之前触发了定时器,则重新开启该定时器,并且将该定时器的值设置成暂停/去激活时该计时器所对应的剩余时间, 或者设置成计时器初始值。
需指出的,上述的回传链路恢复正常的指示可以包括以下至少一项:type-3回传RLF indication、IAB节点的高层发送给MAC层的回传链路恢复正常的指示。对于高层发送给MAC层的回传链路恢复正常的指示可以理解为,高层(upper layer)进行层间指示,告知MAC层回传链路已经恢复正常。
此外,对于IAB节点没有接收到type-2回传RLF indication的其他情况,针对触发的SR按照legacy流程进行处理。
(2)基于回传RLF indication处理触发的BSR
本申请实施例中,回传RLF indication比如为type-2/type-4回传RLF indication,可以用于取消或者暂停已触发的BSR。
可选地,当IAB节点在与其父IAB节点间的回传链路上接收到回传RLF indication时,该IAB节点可以取消或者暂停第一BSR。其中,第一BSR是基于BSR流程决定的会被触发并且没有被取消的BSR。该暂停第一BSR也可以称为去激活第一BSR。
需指出的,第一BSR可以为常规(regular)BSR,也可以为周期性(periodic)BSR。对于regular BSR,如果没有接收到type-2回传RLF indication,则按照legacy流程进行处理。对于regular BSR,在收到type-2回传RLF indication且没有收到type-3回传RLF indication的情况下,说明regular BSR仍然处于非激活态,不能触发SR;而在收到type-2回传RLF indication且收到type-3回传RLF indication的情况下,说明regular BSR已恢复正常,可以触发SR。
可理解的是,由于填充(padding)BSR是在上行授权(UL grant)有多余的情况下,UE利用剩余比特数将BSR情况汇报给网络侧设备,因此,在资源有富余时才出现padding BSR,没必要取消padding BSR。因此,当第一BSR为padding BSR时,第一BSR不会被取消或者暂停。
进一步的,在取消或者暂停第一BSR时,当第一BSR对应的第三定时器在运行时,IAB节点可以停止运行第三定时器。其中,当第一BSR为regular BSR时,第三定时器为重传定时器,比如retxBSR-Timer。或者,当第一BSR 为periodic BSR时,第三定时器为周期性定时器,比如periodicalBSR-Timer。
进一步的,在暂停第一BSR时,当接收到回传链路恢复正常的指示时,IAB节点可以恢复暂停的第一BSR。
进一步的,在暂停第一BSR,且停止运行第三定时器之后,当接收到回传链路恢复正常的指示时,IAB节点可以重新启动第三定时器,并将第三定时器的值设置为第三定时器被暂停时所对应的剩余时间值,或者,将第三定时器的值设置为计时器初始值。其中,该计时器初始值可以协议约定或者网络侧设备配置等,对此不进行限制。
比如,假设第三定时器retxBSR-Timer总共是10子帧,停止运行前倒计时到5子帧,则停止之后恢复具有2种情况:1)将retxBSR-Timer的值设置为10子帧,重新从10子帧倒计时;2)将retxBSR-Timer的值设置为5子帧,从停止时的5子帧倒计时。
需指出的,上述的回传链路恢复正常的指示可以包括以下至少一项:type-3回传RLF indication、IAB节点的高层发送给MAC层的回传链路恢复正常的指示。对于高层发送给MAC层的回传链路恢复正常的指示可以理解为,高层(upper layer)进行层间指示,告知MAC层回传链路已经恢复正常。
可选地,当触发第一BSR的待发送数据中包括RLC control PDU时,该RLC control PDU比如包括RLC状态报告,第一BSR不会被取消或者暂停,即不取消或者暂停第一SR,以保证RLC状态报告的发送。
可选地,在接收到回传RLF indication之后,IAB节点可以停止触发新的BSR,和/或,停止触发新的SR;或者,在满足触发BSR的条件下,IAB节点可以触发新的BSR,且触发后的BSR被判定为暂停态/待处理(pending)态。比如,触发BSR的条件可以为以下至少一项:新到来的上行数据的逻辑信道优先级比UE已经缓存的上行数据中的任意一个逻辑信道组中的逻辑信道优先级都高、在新数据到来前没有任何缓存的上行数据,等等。
比如,如果IAB节点在与其父IAB节点间的回传链路上接收到type-2回传RLF indication,并且BSR流程(procedure)决定了至少一个BSR会被触 发并且没有被取消,则可以取消该至少一个BSR。
又比如,IAB节点接收到type-2回传RLF indication后,仍然可触发新的BSR,但是该BSR会被再判定为去激活态/暂停态,即对该BSR的处理都会停止。具体为,如果IAB节点在与其父IAB节点间的回传链路上接收到type-2回传RLF indication,且还未收到任何从upper layers来的指示说明发生了RLF的链路已经恢复正常,并且BSR procedure决定了至少一个BSR会被触发并且没有被取消,则:1)判定至少一个BSR是去激活的/暂停的BSR,即停止对至少一个BSR的操作,并且停止对应的retxBSR-Timer或者periodicaBSR-Timer(如果计时器在运行的话);2)可选地,不会触发任何SR。
又比如,在暂停/去激活BSR之后,如果IAB节点接收到高层的回传链路恢复正常的指示,即指示“之前接收到type-2回传RLF indication的回传链路已经恢复正常”,则可以重新恢复对之前暂停/去激活的BSR的操作,即恢复之前由于收到type-2回传RLF indication而停止操作的BSR。并且如果该BSR之前触发了计时器,则重新开启该BSR对应的计时器,并且将定时器的值设置成去激活时该计时器所对应的剩余时间,或者设置成计时器初始值。
(3)基于回传RLF indication处理触发的PBSR
本申请实施例中,回传RLF indication比如为type-2/type-4回传RLF indication,可以用于取消或者暂停已触发的PBSR。
可选地,当IAB节点在与其父IAB节点间的回传链路上接收到回传RLF indication时,IAB节点可以取消或者暂停第一PBSR。其中,第一PBSR是基于PBSR流程决定的会被触发并且没有被取消的PBSR。该暂停第一PBSR也可以称为去激活第一PBSR。
进一步的,在暂停第一PBSR时,当接收到回传链路恢复正常的指示时,IAB节点可以恢复暂停的第一PBSR。
需指出的,上述的回传链路恢复正常的指示可以包括以下至少一项:type-3回传RLF indication、IAB节点的高层发送给MAC层的回传链路恢复正常的指示。对于高层发送给MAC层的回传链路恢复正常的指示可以理解 为,高层(upper layer)进行层间指示,告知MAC层回传链路已经恢复正常。
比如,如果IAB节点在与其父IAB节点间的回传链路上接收到type-2回传RLF indication,并且PBSR procedure决定了至少一个PBSR会被触发并且没有被取消,则可以取消该至少一个PBSR。
又比如,如果IAB节点在与其父IAB节点间的回传链路上接收到type-2回传RLF indication,停止触发新的PBSR,且对于已经触发的PBSR遵循现有流程进行处理。
又比如,IAB节点接收到type-2回传RLF indication后,仍然可触发新的PBSR,但是该PBSR会被再判定为去激活态/暂停态,即对该PBSR的处理都会停止。具体为,如果IAB节点在与其父IAB节点间的回传链路上接收到type-2回传RLF indication,且还未收到任何从upper layers来的指示说明发生了RLF的链路已经恢复正常,并且PBSR procedure决定了至少一个PBSR会被触发并且没有被取消,则:1)判定该至少一个PBSR是去激活的/暂停的PBSR,即停止对该至少一个PBSR的操作;2)可选地,不会触发任何SR。
又比如,在暂停/去激活PBSR之后,如果IAB节点接收到高层的回传链路恢复正常的指示,即指示“之前接收到type-2回传RLF indication的回传链路已经恢复正常”,则可以重新恢复对之前暂停/去激活的PBSR的操作,即恢复之前由于收到type-2回传RLF indication而停止操作的PBSR。
本申请实施例中,可选的,若IAB节点的RLC层指示MAC层待传输数据中包括RLC Control PDU,且待传输数据触发第二BSR,则第二BSR在被触发后,不会被取消或者暂停,以保证RLC状态报告的发送。
进一步的,若在IAB节点的上行授权(UL grant)的资源大小小于第二BSR所占用的资源大小时,触发了第二BSR对应的SR,则第二BSR对应的SR在被触发后,不会被取消或者暂停。
也就是说,若RLC层与MAC层进行层间交互,告知MAC层当前待传输数据中包括RLC Control PDU,并且触发BSR的发送,则触发的BSR在后续的所有操作中都不会被取消/暂停;并且当发送该BSR时,若UL grant的 大小比如根据逻辑通道优先级(Logical Channel Prioritization,LCP)准则不足以容纳BSR MAC控制单元(Control Element,CE)以及其子头(header)之和时,触发该BSR对应的SR(并且标记该SR),则该SR在后续的所有操作中都不会被取消/暂停。
可选的,IAB节点的RLC Control PDU仅能通过第一逻辑信道(Logical Channel,LCH)进行传输,且触发第三BSR的待发送数据中包括第一LCH中的待传输数据时,第三BSR在被触发后,不会被取消或者暂停。即,如果规定RLC Control PDU只能通过某一特定的LCH进行传输,则当触发BSR的待发送数据中包含该LCH待传输数据时,该BSR在后续的所有操作中都不会被取消/暂停。
可选的,待处理的第三SR对应的LCH为用于传输RLC Control PDU的LCH,和/或,触发第三SR的第三BSR中包括第一LCH中的待发送数据时,第三SR不会被取消或者暂停。
本申请实施例中,在接收回传RLF indication之后,IAB节点对于上行传输许可的处理可以包括以下至少一项:
IAB节点忽略预配置的上行传输许可,即不使用预配置上行传输许可进行上行数据传输;
当具有RLC control PDU的传输需求时,IAB节点利用预配置的上行传输许可进行RLC control PDU的传输,即仍可使用预配置上行传输许可进行RLC control PDU传输;
IAB节点去激活预配置的上行传输许可。
进一步的,在去激活预配置的上行传输许可之后,当接收的回传链路恢复正常的指示时,IAB节点可以恢复预配置的上行传输许可,或者,IAB节点可以基于IAB节点的父IAB节点的指示,激活预配置的上行传输许可,以使用预配置上行传输许可进行上行数据传输。
需指出的,上述去激活预配置的上行传输许可表示的含义为,暂时忽略预配置的上行传输许可。比如,网络侧配置了一连串/周期的配置授权 (Configured Grant,CG)给UE,这时UE可以直接在网络侧提前配置的时频资源(CG)上传输数据;此处“去激活”的含义为,当某个CG的时刻到来时,UE可以在该CG上发送数据,但是因为收到了回传RLF indication,所以在该CG的时刻不传输数据,而是一直等待,直到RLF的回传链路恢复成功,才再利用CG进行数据传输。进一步的,IAB节点恢复预配置的上行传输许可表示的含义为,不忽略预配置的上行传输许可,即使用预配置上行传输许可进行数据传输。
需要说明的是,本申请实施例提供的上行传输的控制方法,执行主体可以为上行传输的控制装置,或者,该上行传输的控制装置中的用于执行上行传输的控制方法的控制模块。本申请实施例中以上行传输的控制装置执行上行传输的控制方法为例,说明本申请实施例提供的上行传输的控制装置。
