具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
本文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)系统，并且也可用于各种无线通信系统，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)和其他系统。术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(UltraMobile Broadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了NR系统，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系统应用以外的应用。
以下描述提供示例而并非限定权利要求中阐述的范围、适用性或者配置。可以对所讨论的要素的功能和布置作出改变而不会脱离本公开的精神和范围。各种示例可恰适地省略、替代、或添加各种规程或组件。例如，可以按不同于所描述的次序来执行所描述的方法，并且可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
请参见图1，图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端 设备或者用户终端(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)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本申请实施例中并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、WLAN接入点、或其他接入点等)，或者为位置服务器(例如：E-SMLC或LMF(Location Manager Function))，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、WLAN接入点、WiFi节点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系统中的基站为例，但是本申请实施例并不限定基站的具体类型和具体通信系统。
图2显示了一个自回传(integrated access backhaul,IAB)系统示意图。一个IAB节点包括分布式单元(Distributed Unit，DU)功能部分和移动终端(Mobile Termination，MT)功能部分。依靠MT，一个接入点(即IAB node)可以找到一个上游接入点(parent IAB node)，并跟上游接入点的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归属(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。其中，Access为接入，Access IAB node为接入IAB节点，Intermediate IAB节点为中间IAB节点，cable transport为有线传输。
图3是一个IAB系统的CU-DU(Centralized Unit-Distributed Unit)结构图。在一个自回传回路中，所有的IAB节点的DU都连接到一个集中单元(Centralized Unit，CU)节点，由这一个节点通过F1协议(F1 Application  Protocol，或F1 control protocol)对DU进行配置。CU通过无线资源控制(Radio Resource Control，RRC)协议，对MT进行配置。Donor IAB节点没有MT功能部分。
IAB系统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。
为了降低上行数据传输时延，一个IAB节点在收到UE或下游节点的缓存状态报告(Buffer Status Report，BSR)后，可以触发抢先BSR(Pre-emptive BSR)，也可以根据给下游IAB节点或UE发送的上行传输许可(UL grant)，来决定是否触发。两种抢先BSR的触发机制如图4所示。这种根据未来期望接收的数据来确定抢先BSR的方法，使上游节点可以根据预期数据进行提前调度，以降低传输延时。其中，Child Node为子节点，Parent Node为父节点，Regular BSR为常规BSR，Data为数据。
目前抢先BSR使用与长BSR媒体接入控制(Media Access Control，MAC)控制元(Control element，CE)相同的格式进行传输，抢先BSR MAC CE的格式如图5所示，其中，LCG(Logical Channel Group)为逻辑信道组，Buffer Size为缓存大小。
根据目前的协议，一个IAB节点不可以基于收到的抢先BSR触发发往父IAB节点的抢先BSR。但是如果抢先BSR不可以触发抢先BSR，在回传链路较长时，使用回传链路服务低延时要求的业务时，由于多跳上行无线传输带来的长延时问题突出。尽管采用了抢先BSR程序，但是上行传输延时仍会明显大于下行传输延时。基于此，有必要进一步研究基于抢先BSR触发抢先BSR的方法，使得网络能够使用优化的抢先BSR的程序，满足低延时业务的质量要求。
另一方面，如果一个IAB节点(IAB N1)被配置了面向其父IAB节点的抢先BSR的触发和传输，而其父IAB节点(IAB N2)基于收到的抢先BSR向该IAB节点发送上行传输许可，IAB N2可根据这些上行传输许可触发向更上一级父IAB节点(IAB N3)的抢先BSR。然而，由于无线链路传输的不确定性，IAB N2真实接收到的数据量跟预期接收到的数据量相比，可能会有很大的差异；如果预期的数据没有到达，会导致IAB N3根据收到的抢先BSR 向IAB N2发送的上行传输许可浪费；如果IAB N2不根据这些传输许可触发发给IAB N3的抢先BSR，则如果IAB N2收到IAB N1根据这些上行传输许可发送的数据，IAB N2需要触发传统的BSR过程，向IAB N1请求上行传输许可，这中间有较大的传输延时，基于抢先BSR触发抢先BSR的方案需要尽量克服资源浪费的问题。
本申请实施例提供了一种抢先缓存状态报告BSR的配置方法，如图6所示，包括：
步骤101：自回传IAB节点接收抢先BSR的配置参数，所述配置参数用以指示所述IAB节点是否触发迭代抢先BSR，所述迭代抢先BSR为IAB节点基于收到的抢先BSR生成的发给父IAB节点的抢先BSR。
在本申请实施例中，集中单元向IAB节点发送抢先BSR的配置参数，集中单元可IAB节点可以根据实际情况，精确控制是否可以基于抢先BSR来触发抢先BSR，能够在减少传输时延的同时，降低抢先BSR带来的上行传输许可浪费。
本申请实施例中，CU可以配置接入IAB节点(access IAB node)确定上游IAB节点是否以及如何根据收到的抢先BSR进一步触发抢先BSR，包括新的抢先BSR MAC CE格式。一个上游IAB节点可根据收到的抢先BSR里的指示和/或CU的预配置，确定是否进一步触发抢先BSR。这样，CU和IAB节点可以根据情况，精确控制是否可以基于抢先BSR来触发抢先BSR，减少上行传输许可的浪费。
本实施例中，把可以指示父IAB节点生成迭代抢先BSR的抢先BSR称为初始迭代抢先BSR，而把基于收到的抢先BSR生成的抢先BSR称为迭代抢先BSR。
一些实施例中，所述配置参数包括以下至少一项：
可触发迭代抢先BSR的逻辑信道组LCG列表，一具体示例中，UE1配置有LCG1和LCG2，CU配置IAB节点可基于LCG1触发迭代抢先BSR，且没有配置IAB节点基于LCG2触发迭代抢先BSR，若IAB节点收到的来自UE的BSR指示LCG1有数据或LCG1和LCG2均有数据，则可以在发向父IAB节点的初始迭代抢先BSR中指示可给予LCG1触发迭代抢先BSR；若IAB 节点收到的来自UE的BSR指示LCG1无数据而LCG2有数据，则不可在发向父IAB节点的初始迭代抢先BSR中指示触发迭代抢先BSR；
可触发迭代抢先BSR的逻辑信道LCH列表；
可触发迭代抢先BSR的数据无线承载DRB列表；
可触发迭代抢先BSR的业务类型列表；
可触发迭代抢先BSR的用户设备UE的类型，一具体示例中，可配置接入IAB节点根据UE的主要业务来确定是否允许触发初始迭代抢先BSR，例如CU可配置接入IAB节点基于来自超可靠低延迟通信(Ultra-relaible and Low Latency Communication，URLLC)UE的BSR来触发初始迭代抢先BSR；另一具体示例中，CU可直接配置接入IAB节点可以为某一具体UE触发初始迭代抢先BSR，比如，可配置接入IAB节点基于高附加值的UE的BSR触发初始迭代抢先BSR。
可触发迭代抢先BSR的次数(number of iterations)，可以按LCG、LCH、DRB、业务类型或UE配置，可以通过该次数指示业务数据信息可以抢先传输的跳(hop)数；
可触发迭代抢先BSR的时间预算，可以按LCG、LCH、DRB、业务类型或UE配置，可以通过该时间预算指示业务数据缓存信息可在多长预期时间内往上游IAB节点迭代传输。
本实施例中引入可触发迭代抢先BSR的次数以及时间预算，可以避免无限制迭代抢先BSR传输，导致实际可传输数据量跟上行缓存汇报的误差经过多跳后放大到过大而失去了抢先汇报的意义，避免上行传输许可的浪费。另一方面，如果迭代抢先BSR经历的时间过长，IAB节点的上行缓存情况会因为新业务数据的生成而发生变化，抢先BSR汇报的缓存情况跟实际的缓存情况的差异变大，此时基于抢先BSR进一步触发迭代抢先BSR就失去意义。
一些实施例中，所述配置参数还包括以下任一项：
第一指示信息，用于指示所述IAB节点的后续中间节点是否触发迭代抢先BSR；
第二指示信息，用于指示所述IAB节点的后续中间节点基于收到的抢先BSR确定是否触发迭代抢先BSR。
一些实施例中，若所述中间节点到父IAB节点的上行链路发生拥塞，不触发迭代抢先BSR；若所述中间节点到父IAB节点的上行链路不发生拥塞，触发迭代抢先BSR。
一具体实施例中，迭代抢先BSR的触发流程如图8所示，如果CU配置IAB N1，IAB N2和IAB N3触发迭代抢先BSR，IAB N1确定触发和发送迭代抢先BSR，IAB N1向IAB N2发送初始迭代抢先BSR1(其中携带指示迭代参数)，IAB N2根据抢先BSR1携带的迭代参数，确定可进一步触发迭代抢先BSR，IAB N2向IAB N3发送迭代抢先BSR2(其中携带指示迭代参数)。如果IAB N1确定触发和发送一般抢先BSR(即不可迭代的抢先BSR)，IAB N1向IAB N2发送抢先BSR3(其中指示不可迭代)，IAB N2收到抢先BSR3后，确定不进一步触发迭代抢先BSR。
其中，CU可以配置后续中间节点按收到的抢先BSR信息确定触发迭代抢先BSR；或者，CU可以配置后续中间节点按收到的抢先BSR信息确定是否触发迭代抢先BSR。例如，如果一个中间IAB节点到父IAB节点的上行链路发生拥塞，该中间IAB节点可以暂时不触发迭代抢先BSR，待到父IAB节点的上行链路发生的拥塞解除后再正常触发迭代抢先BSR。该上行链路发生拥塞的判断可以根据待传输的上行数据量超过预设门限确定。
一些实施例中，所述配置参数可以携带在BSR媒体接入控制MAC控制元CE中。
一些实施例中，所述BSR MAC CE包括一个或多个逻辑信道标识(Logical Channel Identity，LCID)值，所述一个或多个LCID值分别指示可触发迭代抢先BSR的次数。
一些实施例中，所述方法还包括：
抢先BSR触发后，从所述一个或多个LCID值中选取一个LCID值指示可触发迭代抢先BSR的次数。
本实施例中，可以沿用现有的抢先BSR的MAC CE格式，如图5所示。用新的LCID来指示迭代抢先BSR及迭代次数。一具体示例中，如果预先定义最多可迭代一次，则需要一个新LCID替代原有的LCID即可。当一个IAB节点收到带有该新LCID的抢先BSR后，基于该抢先BSR进一步触发抢先 BSR时，可使用已有的抢先BSR MAC CE格式。另一具体示例中，如果预先定义最多可迭代2次，则需要两个新LCID，LCID1(对应可迭代一次)和LCID2(对应可迭代二次)，当一个IAB节点收到携带LCID2的抢先BSR MAC CE时，确定可以进一步触发抢先BSR，产生携带LCID1的抢先BSR MAC CE。当其父IAB节点收到携带LCID1的抢先BSR MAC CE后，行为同上例。注意，这里的LCID可以指传统LCID(6比特)或eLCID(extended LCID，扩展LCID，8比特或16比特)。这一方法不需要新的BSR MAC CE PDU格式。
一些实施例中，所述BSR MAC CE包括第一比特位图，所述第一比特位图中的每一比特对应一LCG，用以指示是否基于对应的LCG触发迭代抢先BSR。
本实施例中，可以引入一个新的抢先BSR MAC CE格式，在其中引入一个bitmap，每个LCG对应一个bit,用来指示父IAB节点是否可以基于该LCG进一步触发迭代抢先BSR，该MAC CE的格式如图9所示，阴影部分指示的LCGi比特置位(即值为1)表示可基于该LCG的缓存汇报触发迭代抢先BSR，反之不可以。
一些实施例中，所述BSR MAC CE包括第一迭代次数指示，用以指示至少部分LCG的可触发迭代抢先BSR的次数；或
所述BSR MAC CE包括第二迭代次数指示，用以指示至少一个LCG的可触发迭代抢先BSR的次数。
本实施例中，可以引入一个新的抢先BSR MAC CE格式，称为迭代抢先BSR MAC CE，其中携带指示，指示是否可触发迭代抢先BSR或迭代抢先BSR的次数。一种方式中，迭代抢先BSR MAC CE携带一个迭代次数指示，指示一部分或所有LCG的迭代次数，比如仅指示优先级最高的LCG可迭代次数。另一种方式中，迭代抢先BSR MAC CE携带多个迭代次数指示，每个迭代次数指示一个或多个LCG的迭代次数，一具体示例中，每个LCG有一个伴随的迭代次数指示域，指示对应的LCG的抢先BSR的迭代次数；另一具体示例中，多个LCG共有一个伴随的迭代次数指示域，指示这些LCG的抢先BSR的迭代次数。
一些实施例中，所述方法还包括：
若IAB节点基于接收到的第一迭代抢先BSR生成发给父IAB节点的第二迭代抢先BSR，将所述第一迭代抢先BSR中的第一迭代次数指示或第二迭代次数指示的值减1，填写到所述第二迭代抢先BSR中。
即采用新的抢先BSR MAC CE格式，该抢先BSR MAC CE格式包括迭代抢先BSR的次数时，当一个IAB节点基于收到的迭代抢先BSR产生新的迭代抢先BSR时，应该把收到的迭代抢先BSR指示的迭代次数减1，填到生成的迭代抢先BSR中。当收到的迭代抢先BSR中的某一迭代次数指示域为0时，表示不可以基于该迭代次数指示域对应的LCG触发或产生新的迭代抢先BSR，即：当收到的迭代抢先BSR包含一个或多个迭代次数指示域时，且其中至少有一个迭代次数指示域大于0，则可依据大于0的迭代次数指示域对应的LCG的缓存情况产生可进一步触发或产生发向父IAB节点的迭代抢先BSR；若所有的迭代次数指示域均为0，则不可基于该迭代抢先BSR触发或产生发向父IAB节点的迭代抢先BSR。
一些实施例中，所述BSR MAC CE包括时间预算指示，用以指示至少一个LCG的可触发迭代抢先BSR的时间预算。
本实施例中，可以引入一个新的抢先BSR MAC CE格式，称为迭代抢先BSR MAC CE，其中携带指示，指示可迭代触发抢先BSR的预期时间预算。该时间预算可以按LCG配置，一个或多个或所有LCG可有一个时间预算指示，当一个IAB节点收到的迭代抢先BSR中指示的时间预算大于这个IAB节点调度对应的上行传输过程需要的时间预算时，可以进一步触发迭代抢先BSR，反之，则不可以。
一些实施例中，所述方法还包括：
若IAB节点基于接收到的第一迭代抢先BSR生成发给父IAB节点的第二迭代抢先BSR，将所述第一迭代抢先BSR中的时间预算指示的值减去本跳调度的上行传输过程需要的时间预算得到剩余的时间预算，将所述剩余的时间预算作为所述第二迭代抢先BSR的时间预算指示的值。
即采用新的抢先BSR MAC CE格式，该抢先BSR MAC CE格式包括可迭代触发抢先BSR的时间预算时，当IAB节点确定可以触发迭代抢先BSR 时，应该把收到的迭代抢先BSR中指示的时间预算减去本跳调度的上行传输过程需要的时间预算得到剩余的时间预算，填到产生的迭代抢先BSR中，并把产生的新的迭代抢先BSR发向父IAB节点。
本申请实施例还提供了一种抢先缓存状态报告BSR的配置方法，如图7所示，包括：
集中单元CU向自回传IAB节点发送抢先BSR的配置参数，所述配置参数用以指示所述IAB节点是否触发迭代抢先BSR，所述迭代抢先BSR为IAB节点基于收到的抢先BSR生成的发给父IAB节点的抢先BSR。
本申请实施例中，CU可以配置接入IAB节点(access IAB node)确定上游IAB节点是否以及如何根据收到的抢先BSR进一步触发抢先BSR，包括新的抢先BSR MAC CE格式。一个上游IAB节点可根据收到的抢先BSR里的指示和/或CU的预配置，确定是否进一步触发抢先BSR。这样，CU和IAB节点可以根据情况，精确控制是否可以基于抢先BSR来触发抢先BSR，减少上行传输许可的浪费。
可触发迭代抢先BSR的逻辑信道组LCG列表，一具体示例中，UE1配置有LCG1和LCG2，CU配置IAB节点可基于LCG1触发迭代抢先BSR，且没有配置IAB节点基于LCG2触发迭代抢先BSR，若IAB节点收到的来自UE的BSR指示LCG1有数据或LCG1和LCG2均有数据，则可以在发向父IAB节点的初始迭代抢先BSR中指示可给予LCG1触发迭代抢先BSR；若IAB节点收到的来自UE的BSR指示LCG1无数据而LCG2有数据，则不可在发向父IAB节点的初始迭代抢先BSR中指示触发迭代抢先BSR；
可触发迭代抢先BSR的逻辑信道LCH列表；
可触发迭代抢先BSR的数据无线承载DRB列表；
可触发迭代抢先BSR的业务类型列表；
可触发迭代抢先BSR的用户设备UE的类型，一具体示例中，可配置接入IAB节点根据UE的主要业务来确定是否允许触发初始迭代抢先BSR，例如CU可配置接入IAB节点基于来自超可靠低延迟通信(Ultra-relaible and Low Latency Communication，URLLC)UE的BSR来触发初始迭代抢先BSR；另一具体示例中，CU可直接配置接入IAB节点可以为某一具体UE触发初始 迭代抢先BSR，比如，可配置接入IAB节点基于高附加值的UE的BSR触发初始迭代抢先BSR。
可触发迭代抢先BSR的次数(number of iterations)，可以按LCG、LCH、DRB、业务类型或UE配置，可以通过该次数指示业务数据信息可以抢先传输的跳(hop)数；
可触发迭代抢先BSR的时间预算，可以按LCG、LCH、DRB、业务类型或UE配置，可以通过该时间预算指示业务数据缓存信息可在多长预期时间内往上游IAB节点迭代传输。
本实施例中引入可触发迭代抢先BSR的次数以及时间预算，可以避免无限制迭代抢先BSR传输，导致实际可传输数据量跟上行缓存汇报的误差经过多跳后放大到过大而失去了抢先汇报的意义，避免上行传输许可的浪费。另一方面，如果迭代抢先BSR经历的时间过长，IAB节点的上行缓存情况会因为新业务数据的生成而发生变化，抢先BSR汇报的缓存情况跟实际的缓存情况的差异变大，此时基于抢先BSR进一步触发迭代抢先BSR就失去意义。
一些实施例中，所述配置参数还包括以下任一项：
第一指示信息，用于指示所述IAB节点的后续中间节点是否触发迭代抢先BSR；
第二指示信息，用于指示所述IAB节点的后续中间节点基于收到的抢先BSR确定是否触发迭代抢先BSR。
一些实施例中，若所述中间节点到父IAB节点的上行链路发生拥塞，不触发迭代抢先BSR；若所述中间节点到父IAB节点的上行链路不发生拥塞，触发迭代抢先BSR。
一具体实施例中，迭代抢先BSR的触发流程如图8所示，如果CU配置IAB N1，IAB N2和IAB N3触发迭代抢先BSR，IAB N1确定触发和发送迭代抢先BSR，IAB N1向IAB N2发送初始迭代抢先BSR1(其中携带指示迭代参数)，IAB N2根据抢先BSR1携带的迭代参数，确定可进一步触发迭代抢先BSR，IAB N2向IAB N3发送迭代抢先BSR2(其中携带指示迭代参数)。如果IAB N1确定触发和发送一般抢先BSR(即不可迭代的抢先BSR)，IAB N1向IAB N2发送抢先BSR3(其中指示不可迭代)，IAB N2收到抢先BSR3后， 确定不进一步触发迭代抢先BSR。
其中，CU可以配置后续中间节点按收到的抢先BSR信息确定触发迭代抢先BSR；或者，CU可以配置后续中间节点按收到的抢先BSR信息确定是否触发迭代抢先BSR。例如，如果一个中间IAB节点到父IAB节点的上行链路发生拥塞，该中间IAB节点可以暂时不触发迭代抢先BSR，待到父IAB节点的上行链路发生的拥塞解除后再正常触发迭代抢先BSR。该上行链路发生拥塞的判断可以根据待传输的上行数据量超过预设门限确定。
一些实施例中，所述配置参数携带在BSR媒体接入控制MAC控制元CE中。
一些实施例中，所述配置参数可以携带在BSR媒体接入控制MAC控制元CE中。
