本申请属于通信技术领域，具体涉及一种回传一体化(Integrated Access Backhaul，IAB)节点的冲突处理方法、装置、设备及可读存储介质。
背景技术
IAB的分布式单元(Distributed Unit，DU)和移动终端(Mobile Termination，MT)功能部分进行收发操作时，受硬件限制(半双工，功率谱密度(Power spectral density，PSD)平衡，功率受限)/干扰限制/资源复用限制等，会出现收发冲突的问题(上行或下行冲突，或资源类型指示冲突等)。同理，MT主小区组(Master cell group，MCG)和MT辅小区组(Secondary Cell Group，SCG)进行收发操作时，也会出现冲突问题。
在MT双链接的场景，针对MCG的服务小区(serving cell)以及其对应的DU小区(cell)，和SCG的serving cell以及其对应的DU cell，调度/资源指示/功率控制等机制是互相独立的，这导致冲突问题会更加严重。

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在没有作出创造性劳动前提下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，而不用于描述指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，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和”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。
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)系统，还可用于其他无线通信系统，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。本申请实施例中的术语“系统”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系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用，如第6代(6 th Generation，6G)通信系统。
一、关于IAB系统
参见图1，示意一个接入和回传一体化(Integrated Access Backhaul，IAB)系统。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，一个接入节点(即IAB节点(node))可以找到一个上游接入节点(比如，父IAB节点(parent IAB node))，并与上游接入节点的DU建立无线连接，该无线连接被称为backhaul链接(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可以为终端提供接入服务。一个自回传回路包含一个宿主(donor)IAB节点，donor IAB节点有直接相连的有线传输网。
图2是一个IAB系统的中心单元-分布式单元(Centralized Unit-Distributed Unit，CU-DU)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CU节点，由这一个节点通过F1-AP协议进行对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。
二、关于DU和MT的双工(duplexing)方式
为了实现频分复用(frequency division multiplex，FDM)/空分复用(Space Division Multiplexing，SDM)的资源复用，DU和MT的非时分复用(non-TDM)操作方式有以下几种：
(1)DU-发送(TX)和MT-TX；或表示为，DU配置为下行(Downlink，DL)，MT配置为上行(Uplink，UL)；或表示为，DU进行DL发送，MT进行UL发送。
(2)DU-接收(RX)和MT-RX；或表示为，DU配置为UL，MT配置为DL；或表示为，DU进行UL接收，MT进行DL接收。
(3)DU-TX和MT-RX；或表示为，DU配置为DL，MT配置为DL；或表示为，DU进行DL发送，MT进行DL接收。
(4)DU-RX和MT-TX；或表示为，DU配置为UL，MT配置为UL；或表示为，DU进行UL接收，MT进行UL发送。
三、关于IAB小区专用信令(cell-specific signaling)的资源类型配置：
IAB DU的资源类型分为硬(Hard)，软(soft)和不可用(notavailable，NA)类型。在Hard类型的资源上，IAB DU可以执行收发操作，这时IAB节点可以忽略所有的MT的收发。IAB DU的cell-specific signaling发送占用的资源被视为Hard资源：
√DU的同步信号块(Synchronization Signal and PBCH block，SSB)传输资源，包括小区定义SSB(Cell Defining SSB，CD-SSB)和非CD-SSB；
√在DU接收配置的随机接入信道(Random Access Channel，RACH)场合；
√DU处的定期信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)传输；
√在DU接收调度请求(Scheduling Request，SR)的计划资源。
四、关于IAB DU的soft资源类型：
IAB DU的资源类型分为Hard，soft和NA类型。在Soft类型的资源上，如果IAB DU的收发操作不影响MT的收发行为，IAB DU可以使用该soft资源。
五、关于终端在多个服务小区(multiple serving cell)配置下半双工限制：
终端在multiple serving cell配置下，如果终端受半双工限制，对终端的行为和基站的调度限制做了规定。部分总结如下：
情况1：如果小区(cell)间的UL/DL发生冲突，对终端的信道传输行为 有如下限定：
SSB接收和物理上行共享信道(Physical Uplink Shared Channel，PUSCH)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)、物理随机接入信道(Physical Random Access Channel，PRACH)、探测参考信号(Sounding Reference Signal，SRS)发送冲突时，优先接收；PRACH发送和物理下行控制信道(Physical downlink control channel，PDCCH)、物理下行共享信道(Physical downlink shared channel，PDSCH)、信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)接收冲突时，优先发送PRACH；UL信道发送与跨时隙(slot)的PDSCH接收冲突时，优先UL发送；DL信道接收与跨slot的PUSCH冲突时，优先DL接收。
情况2：如果一个serving cell上配置了控制资源集(Control resource set，CORESET)#0，终端不期待cell的相应的时域位置上配置为UL符号(symbol)。
情况3：规定一个参考服务小区(reference serving cell)(或者参考小区(reference cell))，reference cell上的收发优先级较高。如果reference cell指示为UL/DL，那么终端不期待non-reference cell在相应的时域位置指示为DL或UL；如果reference cell配置为DL或调度了DL接收，那么终端不期待非参考小区(non-reference cell)在相应的时域位置有UL调度；如果reference cell配置为UL或调度了UL发送，那么终端不期待non-reference cell在相应的时域位置有DL调度；如果reference cell上配置了PUCCH、PUSCH、PRACH、SRS的发送或配置为UL symbol，终端不会接收non-reference cell在相应的时域位置接收配置的PDCCH、PDSCH、CSI-RS；如果reference cell上配置了PDCCH、PDSCH、CSI-RS的接收或配置为DL symbol，终端不会接收non-reference cell在相应的时域位置发送配置的PUCCH、PUSCH、PRACH、SRS；如果reference cell上配置了PUCCH、PUSCH、PRACH或SRS发送或PDCCH、PDSCH、CSI-RS接收，UE在non-reference cell在相应的时域位置的行为同灵活符号(Flexible symbol)上的行为一致。
情况4：终端不期待第一个下行控制信息(Downlink Control Information，DCI)在第一个cell上调度了DL或UL，而第二个DCI在相应的时域位置上调度了UL或DL。
情况5：如果reference cell和non-reference cell在不同的频带(frequency band)，如果UL或DL在reference cell和non-reference cell为不同方向，不要求终端接收配置的PDCCH、PDSCH、CSI-RS，终端在相应的时域位置也不期待配置的PUCCH、PUSCH、PRACH、SRS；特别地，终端优先发送在non-reference cell上动态调度的UL传输，即便reference cell配置为DL或配置了PDCCH、PDSCH、CSI-RS接收。
六、关于终端在双连接(Dual-Connectivity，DC)下的功率共享。
如果终端处于双连接状态，其发送功率可以在主小区组(Master Cell Group，MCG)link和辅小区组(Secondary Cell Group，SCG)link之间共享。MCG link和SCG link间的功率共享可以分为半静态和动态的功率共享。
对于半静态的功率共享，MCG link和SCG link所配置的最大上行发送功率之和小于或等于终端的总发送功率。对于新空口(New Radio，NR)的双连接(NN-DC)，所述的MCG link和SCG link配置的最大发送功率只适用于MCG link和SCG link可以存在同时发送的时刻，例如同为UL symbol的时刻，一个为UL symbol一个为Flexible symbol的时刻。
七、关于初始接入信令：
终端进行初始接入可分为四步随机接入(4-step RACH)和两步随机接入(2-step RACH)。4-step RACH的信令包括：消息1(MSG1)、消息2(MSG2)、消息3(MSG3)和消息4(MSG4)。2-step RACH的信令包括消息A(MSGA)和消息B(MSGB)。
本文中终端也可以称作终端设备或者用户终端(User Equipment，UE)，终端可以是手机、IAB MT、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(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：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的具体类型。
本文中网络侧设备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 TransceiverStation，BTS)、无线电基站、无线电收发机、基本服务集(BasicServiceSet，BSS)、扩展服务集(ExtendedServiceSet，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、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，所述基站不限于指定技术词汇，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，但是并不限定基站的具体类型。

下面结合方案一和方案二介绍本申请的实施方式。
方案一：DU cell与MT cell间的冲突处理
参见图4，示意三种冲突场景，即DU cell和同信道(co-channel)MT cell间的冲突(DU cell#1和MT cell#1)，DU cell和非同信道(non-co-channel)MT cell间的冲突(DU cell#1和MT cell#2，以及DU cell#1和MT cell#3)。
IAB DU和MT之间发生资源指示/调度冲突时，采取以下措施。
所述的冲突情况包括但不限于以下至少一种：
(1)DU cell和MT cell支持TDM的资源复用方式，但IAB节点接收到多个冲突的资源类型指示；
例如，在某个符号上，一个指示/调度DU进行收发操作，另一个指示/调度DU不能进行收发操作。
(2)DU cell和MT cell支持non-TDM的资源复用方式，但受半双工(half duplex)限制，DU cell和MT cell在某时刻指示/调度为全双工，即DU cell与MT serving cell的TDD方向出现冲突；
例如，在某个symbol上，一个指示/调度为UL symbol，另一个指示/调度为DL symbol。
(3)DU cell和MT cell在某时刻指示/调度为同时发送，但DU和MT进行功率共享时，DU/MT的发送不能同时满足发送功率要求；
例如，SSB、CSI-RS或PDCCH在CORESET#0的每个资源单元的能量(Energy per resource element，EPRE)要求，通过UL功控和调度确定的UL发送功率要求，DU和MT间的功率谱密度(Power spectral density，PSD)平衡的要求等。
其中，PSD平衡性可由EPRE差值等表示，大于某个差值，则认为PSD不平衡。
(4)DU cell和MT cell在某时刻指示/调度为同时接收或者一发一收，但如果其中一方对另一方干扰(即能量干扰)大于门限值；
其中，能量干扰可由参考信号接收功率(Reference Signal Received Power， RSRP)/接收信号强度指示(Received Signal Strength Indication，RSSI)/参考信号接收质量(Reference Signal Received Quality，RSRQ)/信噪比(SIGNAL NOISE RATIO，SNR)/信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)等表示。
(5)DU cell和MT cell在某时刻指示/调度为同时接收，但DU和MT间的PSD不平衡；
其中，PSD平衡性可由EPRE差值等表示，大于某个差值，则认为PSD不平衡。
所述措施：
(1)IAB node需要根据DU和MT的优先级原则，低优先级的发送进行功率缩放(power scaling)，或直接放弃低优先级的发送/接收。
(2)限制信号或信道的发送/接收，避免DU和MT的收发出现冲突。尤其针对下述优先级原则中所提及的冲突。
例如，限制CU的资源配置，IAB node或parent node不期待存在造成冲突的配置；
或者，限制parent node的动态资源指示，IAB node不期待存在造成冲突的资源动态；
或者，限制IAB node或parent node的调度/传输参数设置，IAB node不期待存在造成冲突的调度/参数设置。
所述措施中的优先级原则包括：
DU发送与MT发送间的优先级原则，参见实施例一；
DU发送与MT接收间的优先级原则，参见实施例二；
DU接收与MT发送间的优先级原则，参见实施例三；
DU接收与MT接收间的优先级原则，参见实施例四。
另外，IAB node可以获取MT serving cell上对应的资源类型信息(例如Hard、Soft或NA等)，所述对应的资源类型信息可以是parent node DU的资源类型配置，或者是parent node调度该MT serving cell时计划使用的资源类型。
好处：根据现有技术Parent node可以知道IAB DU cell的资源类型或者 TDD配置，IAB node也可以知道parent node所调度的MT cell的TDD。再结合所述的方法，IAB DU和parent node可以进行调度/配置协调，协调信号/信道的发送/接收，以便缓解冲突的发生。
方案二：MT cell间的冲突处理，图5示例两种冲突场景，同一个小区组(cell group，CG)的cell间的冲突，以及不同CG间的Cell间的冲突。
IAB node的MT获取MT serving cell上对应的资源类型信息(例如Hard、Soft或NA等)，所述对应的资源类型信息可以是parent node DU的资源类型配置，或者是parent node调度该MT serving cell时计划使用的资源类型。
如果IAB MT的serving cell某个symbol被配置为UL symbol或DL symbol，但是serving cell上对应的资源类型信息指示MT不可用该symbol，那么IAB MT在该symbol上忽略该serving cell对其行为的影响。该规则至少适用于以下一种情况：
情况1：IAB MT配置有multiple serving cell且收发受half duplex限制，确定MT的收发行为/限制调度节点的行为。
情况2：IAB MT配置有MCG和SCG，MCG的serving cell和SCG的serving cell中某symbol同时配为UL symbol，进行半静态功率共享的行为。
