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术语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/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。
为了便于理解本申请实施例,首先说明以下内容。
请参见图1,图1示出本申请实施例可应用的一种IAB系统的示意图。在IAB系统中,一个IAB节点包括MT功能部分和DU功能部分。依靠MT, IAB节点可以找到一个/多个父IAB节点(parent IAB node,或称为上游IAB节点),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/多个施主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。需指出的,图1中示出了具有一个parent IAB节点和一个donor IAB节点的实例,但本申请实施例不以此为限。
图2是本申请实施例中IAB系统的控制单元-分布单元(Centralized Unit-Distributed Unit,CU-DU)的结构示意图。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,并由该CU节点通过F1应用(F1-Aplication,F1-AP)协议对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。
本申请实施例中,IAB节点的DU和MT之间的双工(duplexing)方式分为半双工(Half duplex)和全双工(Full duplex)的方式。在Full duplex的情况下,DU/MT可以同时收发。
可选的,IAB节点的DU和MT在时分复用(Time Domain Multiplexing,TDM)的复用方式下,DU的收发操作和MT的收发操作是时分复用的(TDMed)。此时的双工方式为半双工。
可选的,IAB节点的DU和MT在频分复用(Frequency Domain Multiplexing,FDM)或者空分复用(Space Domain Multiplexing,SDM)的复用方式下,DU和MT的收发操作方式包括但不限于以下至少一种双工方式:
1)DU-TX&MT-TX;即,DU配置为下行(Downlink,DL),MT配置为上行(Uplink,UL);或者,DU存在实际的DL发送,MT存在实际的UL发送;
2)DU-RX&MT-RX;即,DU配置为UL,MT配置为DL;或者,DU存在实际的UL接收,MT存在实际的DL接收;
3)DU-TX&MT-RX;即,DU配置为DL,MT配置为DL;或者,DU 存在实际的DL发送,MT存在实际的DL接收;
4)DU-RX&MT-TX;即,DU配置为UL,MT配置为UL;或者,DU存在实际的UL接收,MT存在实际的UL发送。
需指出的,在本申请实施例中,DU TX和DU DL可以通用,MT TX和MT UL可以通用,DU RX和DU UL可以通用,MT RX和MT DL可以通用。
可理解的,在本申请实施例中,TDM、SDM和FDM这三种复用方式均涉及跨跳之间的协调调度。这三种复用方式的说明如下:
1)时分复用(TDM)是指一个IAB节点在不同的时域资源上操作IAB MT和IAB DU。比如,IAB MT在某一时域资源上从其父IAB节点接收物理下行共享信道(Physical Downlink Shared Channel,PDSCH)或者向其父IAB节点发送物理上行共享信道(Physical Uplink Shared Channel,PUSCH);IAB DU在另一时域资源上从其子IAB节点或UE接收PUSCH或者向其子IAB节点或UE发送PDSCH。
2)空分复用(SDM)是指一个IAB节点在同样的时频资源上操作IAB MT和IAB DU。比如,IAB MT从其父IAB节点接收PDSCH或者向其父IAB节点发送PUSCH,以及,IAB DU从其子IAB节点或UE接收PUSCH或者向其子IAB节点或UE发送PDSCH,在相同的时频域资源上传输。
3)频分复用(FDM)是指一个IAB节点在不同的频率资源上同时操作IAB MT和IAB DU。比如,IAB MT从其父IAB节点接收PDSCH或者向其父IAB节点发送PUSCH,以及,IAB DU从其子IAB节点或UE接收PUSCH或者向其子IAB节点或UE发送PDSCH,在相同的时域资源上传输。
本申请实施例中,所涉及的全双工(Full Duplex)场景包括:DU-TX&MT-RX和DU-RX&MT-TX。比如,全双工可以是指一个IAB节点同时从其父IAB节点接收PDSCH和向其子IAB节点或UE发送PDSCH,或者一个IAB节点在同样的时频资源上同时向其父IAB节点发送PUSCH和从其子IAB节点或UE接收PUSCH。
可选的,对于IAB DU的资源配置,Donor node CU可以通过F1-AP(或者说F1-C)信令比如gNB-DU resource configuration来配置DU的时域资源。其中,配置每个时隙中符号(symbol)的传输的类型(或者说是符号的传输 方向),符号类型(或者说符号方向)包括DL symbol、UL symbol和灵活(flexible)symbol。配置DU的每个类型的符号的可用情况,包括硬(hard)/软(soft)/不可用(Not Available)类型的配置。可用情况是以符号类型为配置单位的。具体的,
-若DL/UL/flexible symbol被配置为hard,则IAB DU可以在该符号上发送/接收/发送或者接收;
-若DL/UL/flexible symbol被配置为soft,且IAB DU的发送/接收/发送或接收不影响MT的发送或接收,则IAB DU可以在该符号上发送/接收/发送或接收;否则,IAB DU在该符号上不进行发送/接收/发送或接收。进一步地,IAB父节点可以指示IAB DU的soft symbol的可用情况。
-若DL/UL/flexible symbol被配置为Not Available(NA),则IAB DU在该符号上不发送也不接收。
可选的,对于IAB MT的资源配置,IAB MT的时域资源是由CU/父IAB节点配置,可以通过RRC信令中的TDD config、下行控制信息(Downlink Control Information,DCI)等配置。IAB MT的符号类型为DL/UL/Flexible symbol。进一步地,DCI格式2_0(format 2_0)可以动态改写配置为flexible symbol的资源,或者可以通过配置授权(configured grant)动态改写配置为flexible symbol的资源。
可选的,在本申请实施例中,对于IAB MT和IAB DU的资源方案可以至少包括如下5种:
方案一:IAB MT的资源配置和/或指示为灵活(flexible)资源,IAB DU的资源配置和/或指示为DL资源;
方案二:IAB MT的资源配置和/或指示为灵活资源,IAB DU的资源配置和/或指示为UL资源;
方案三:IAB MT的资源配置和/或指示为DL资源,IAB DU的资源配置和/或指示为灵活资源;
方案四:IAB MT的资源配置和/或指示为UL资源,IAB DU的资源配置和/或指示为灵活资源;
方案五:IAB MT的资源配置和/或指示为灵活资源,IAB DU的资源配 置和/或指示为灵活资源。
需指出的,上述方案一至方案五中,IAB MT的资源与IAB DU的资源对应,此对应可理解为相同的时域资源,而频域资源不做限制。IAB MT的资源可以包括但不限于symbol、时隙slot、帧frame等。IAB DU的资源可以包括但不限于symbol、时隙slot、帧frame等。
在方案一、方案二和方案五下,IAB MT/DU的传输方向可以根据以下至少一项确定:IAB MT/DU的优先关系、IAB节点的复用能力、信令指示、IAB DU的传输方向。而在方案三、方案四和方案五下,IAB MT/DU的传输方向可以根据以下至少一项确定:IAB MT/DU的优先关系、IAB节点的复用能力、信令指示、IAB MT的传输方向。
本申请实施例中,针对不同的信号/信道可以采取不同的传输行为。例如,对于UL传输,在冲突的情况下,对于探测参考信号(Sounding Reference Signal,SRS)可以仅取消冲突的符号的传输,传输剩余符号上的SRS;对于物理上行控制信道(Physical Uplink Control Channel,PUCCH)/PUSCH/随机接入信道(Physical Random Access Channel,PRACH)的传输,若部分符号冲突,则可以取消整个PUCCH/PUSCH/PRACH的传输。对于DL传输,对于DL定位参考信号(Positioning Reference Signal,PRS)的传输,若高层调度在flexible symbol接收,则可以进行接收;若高层调度物理下行控制信道(Physical Downlink Control Channel,PDCCH)/PDSCH/信道状态信息参考信号(Channel State Information-Reference Signal,CSI-RS)在flexible symbol上接收,则可以不接收。
需指出的,在本申请实施例中的,IAB节点的MT可以简写为IAB MT,IAB节点的DU可以简写为IAB DU。
可选的,在本申请实施例中的,对于IAB DU的传输,可以是IAB DU接收,即IAB DU调度子IAB节点发送,也就是UL传输;也可以是IAB DU发送,即IAB DU指示子IAB节点接收,也就是DL传输。
可选的,在本申请实施例中的“默认”可理解为假设。
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传输处理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传输处理方法的流程图,该方法由IAB节点执行。如图3所示,该方法包括如下步骤:
步骤31:IAB节点的MT在第一资源上执行第一操作,和/或,IAB节点的DU在第二资源上执行第二操作。
可选的,第一操作可以包括以下至少一项:发送、接收、不发送、不接收。第二操作可以包括以下至少一项:发送、接收、不发送、不接收。
可选的,第一资源为IAB MT的配置和/或指示为灵活资源的资源。第一资源与第二资源对应,第二资源为IAB DU的配置和/或指示为UL资源(对应上述方案二)、DL资源(对应上述方案一)或者灵活资源(对应上述方案五)的资源。第一资源与第二资源对应可理解为:第一资源与第二资源是相同的时域资源比如symbol。至于第一资源与第二资源的频域资源不进行限制,可以相同也可以不相同。
可选的,第一资源可以包括但不限于symbol、slot、frame、微秒、毫秒、秒等,第二资源可以包括但不限于symbol、slot、frame、微秒、毫秒、秒等,在此不对第一资源和第二资源进行限制。
本申请实施例的传输处理方法,IAB节点的MT可以在第一资源上执行第一操作,和/或,IAB节点的DU可以在第二资源上执行第二操作;所述第一资源为所述MT的配置和/或指示为灵活资源的资源;所述第一资源与第二资源对应,所述第二资源为所述DU的配置和/或指示为UL资源、DL资源或者灵活资源的资源。由此,可以在IAB节点的MT和/或DU的对应资源配置为灵活资源的情况下,明确MT和/或DU的传输行为,从而可以实现IAB MT和IAB DU在灵活资源上同时传输,从而提高资源利用率。
一种实施方式中,在上述方案一下,也就是某一时刻,IAB MT的资源为flexible资源,IAB DU的资源为DL资源。IAB节点根据提前获取的DCI指示,可以确定IAB MT在对应的flexible资源上是否存在调度。或者,IAB节点根据提前获取的配置的发送/接收,可以确定IAB MT在对应的flexible资源上是否存在调度。可选的,上述配置的发送/接收,或者DCI指示的调度,可以是指同步信号块(Synchronization Signal and PBCH block,SSB)/类型0搜索空间(type 0 search space)/PDCCH/PDSCH/CSI-RS/DL PRS的接收,或 者是PRACH/PUCCH/PUSCH/SRS的发送。若IAB MT没有被配置为检测DCI format 2-0,对于配置的发送/接收,至少可以确定SSB的接收。其他的高层配置的收发会被DCI更改,但是可以规定某高层配置的收发不能被DCI更改。这里对应的flexible资源就是与IAB DU的DL资源为相同时域资源的资源。
另一种实施方式中,上述方案一或方案二下,对于某一时间点,IAB MT的时分双工(TDD)方向为flexible(可简写为F),IAB DU的TDD方向为DL/UL:
(1)若预定义、预配置和/或配置了IAB MT优先,则满足以下至少一项:
1)无论DU资源类型配置是否允许IAB DU调度,IAB DU不能进行调度。
2)如果DU资源类型配置允许IAB DU调度,则IAB DU采取保守的方式调度,parent IAB调度IAB MT时具有一定的调度激进性。
可选的,IAB DU不能确定IAB MT的flexible资源有无调度,和/或,IAB DU不能确定IAB MT的flexible资源上的调度为UL/DL;IAB DU默认parent IAB可做任意UL/DL调度。
可选的,若IAB DU能够确定IAB MT的flexible资源有无调度,和/或确定IAB MT的flexible资源上的调度为UL/DL,IAB DU根据IAB MT的调度方向进行调度。
进一步的,针对确定有无调度:IAB DU根据提前获取的DCI指示,可以确定有无调度;或者,IAB DU根据提前获取的配置的发送/接收(configured transmission/reception),可以确定有无调度,其中,在IAB MT没有被配置为检测DCI format 2-0的前提下,至少可以确定SSB的接收,其他的高层配置的收发会被DCI更改,但是可以从新规定某高层配置的收发不能被DCI更改。
进一步的,针对确定IAB MT的flexible资源上的调度为UL/DL:IAB DU根据提前获取的DCI指示,可以确定TDD方向;或者,IAB DU根据提前获取的DCI format 2-0指示,确定TDD方向;或者,IAB DU根据提前获取的配置的发送/接收,可以确定TDD方向,其中,在IAB MT没有被配置为检测DCI format 2-0的前提下,至少可以确定SSB的接收,其他的高层配置的 收发会被DCI更改,但是可以从新规定某高层配置的收发不能被DCI更改。
可选的,parent IAB节点调度的激进性,至少满足以下至少一项假设:
parent IAB节点在IAB MT的flexible资源上的调度为UL时,假设MT UL&DU DL同时进行;
parent IAB节点在IAB MT的flexible资源上的调度为DL时,假设MT DL&DU DL同时进行;
parent IAB节点在IAB MT的flexible资源上调度时,假设IAB DU无调度;
根据IAB的复用能力(duplexing capability)确定使用上述何种假设。
(2)若预定义、预配置和/或配置了IAB DU优先,则满足以下至少一项:
1)至少DU资源类型配置允许IAB DU调度的情况下,Parent IAB节点不能调度IAB MT。
2)parent IAB节点调度IAB MT时采取保守调度,即不能影响到IAB DU调度的发送行为/性能;IAB DU调度具有一定激进性。
可选的,对于IAB DU调度的激进性:IAB DU调度时可以假设parent IAB节点无调度;或者,IAB DU调度时可以假设Parent IAB节点调度为UL/DL。
可选的,parent IAB节点调度IAB MT时,可以假设存在DU调度。并且,IAB DU调度时可以假设parent IAB节点无调度;或者,IAB DU调度时可以假设parent IAB节点调度为UL/DL。
可选的,parent IAB节点如果提前知道DU有无调度,可以相应的提高parent IAB节点的调度的激进性,例如DU上报调度计划(scheduling plan)等。
(3)若IAB MT和IAB DU间无优先级关系,可以预设IAB MT和IAB DU按照约定的复用实例(multiplexing case)调度。例如,始终假设同发,或者同收,或者根据CU/parent的复用方式(multiplexing mode)指示确定IAB MT和IAB DU间的multiplexing case,或者根据IAB上报的期待multiplexing mode确定IAB MT和IAB DU间的multiplexing case。
另一种实施方式中,在上述方案二下,也就是某一时刻,IAB MT的资源为flexible资源,IAB DU的资源为UL资源。IAB节点根据提前获取的DCI 指示,可以确定IAB MT在对应的flexible资源上是否存在调度。或者,IAB节点根据提前获取的配置的发送/接收,可以确定MT在对应的flexible资源上是否存在调度。其中,上述配置的发送/接收,或者是DCI指示的调度,可以是指SSB/type 0 search space/PDCCH/PDSCH/CSI-RS/DL PRS的接收,或者是PRACH/PUCCH/PUSCH/SRS的发送。这里对应的flexible资源就是与IAB DU的UL资源为相同时域资源的资源。
另一种实施方式中,在上述方案一下,也就是某一时刻,IAB MT的资源为flexible资源,IAB DU的资源为DL资源。IAB节点根据提前获取的DCI指示,可以确定IAB MT在对应的flexible资源上的时分双工(TDD)方向。或者,IAB节点根据提前获取的DCI format 2-0指示,确定IAB MT在对应的Flexible资源上的TDD方向。或者,IAB节点根据提前获取的配置的发送/接收,可以确定IAB MT在对应的Flexible资源上的TDD方向。这里对应的flexible资源就是与IAB DU的DL资源为相同时域资源的资源。
另一种实施方式中,在上述方案二下,也就是某一时刻,IAB MT的资源为flexible资源,IAB DU的资源为UL资源。IAB节点根据提前获取的DCI指示,可以确定IAB MT在对应的flexible资源上的TDD方向。或者,IAB节点根据提前获取的DCI format 2-0指示,可以确定IAB MT在对应的Flexible资源上的TDD方向。或者,IAB节点根据提前获取的配置的发送/接收,可以确定IAB MT在对应的Flexible资源上的TDD方向。这里对应的flexible资源就是与IAB DU的UL资源为相同时域资源的资源。
需指出的,在上述方案五下,也就是某一时刻,IAB MT的资源为灵活资源,IAB DU的资源为灵活资源。若默认或假设IAB DU的灵活资源为DL资源,由于IAB MT的资源为灵活资源,故类似于方案一,相应方法与方案一下方法相同。而若默认或假设IAB DU的灵活资源为UL资源,由于IAB MT的资源为灵活资源,故类似于方案二,相应方法与方案二下方法相同。
本申请实施例中,基于调度和/或配置的IAB MT在第一资源上的传输,IAB MT可以具有不同的传输行为。可选的,当第二资源配置和/或指示为DL资源(对应上述方案一),或者,第二资源配置和/或指示为灵活资源(对应上述方案五)且默认第二资源为DL资源时,上述在第一资源上执行第一操 作可以包括以下至少一项:
当默认第一资源为UL或DL资源,且调度和/或配置IAB MT的UL传输在第一资源上时,IAB MT在第一资源上不进行发送;
当默认第一资源为UL或DL资源,且调度和/或配置IAB MT的DL传输在第一资源上时,IAB MT在第一资源上进行接收;
当没有调度和/或配置IAB MT的UL传输在第一资源上,且默认第一资源为DL资源时,IAB MT在第一资源上进行接收;
当没有调度和/或配置IAB MT的UL传输在第一资源上,且默认第一资源为灵活资源时,IAB MT在第一资源上不进行发送和接收;
当调度第一资源为灵活资源时,IAB MT在第一资源上不进行发送和接收;
IAB MT根据IAB节点的复用能力和/或预设规则,在第一资源上执行第一操作。比如,该预设规则可以包括以下至少一项:1)在默认MT UL和DU DL同时进行的情况下,IAB MT为UL发送,或者parent IAB节点调度IAB MT在灵活资源上为UL发送;2)在默认MT DL和DU DL同时进行的情况下,IAB MT为DL接收,或者parent IAB节点调度IAB MT在灵活资源上为DL接收;3)在默认IAB DU无传输的情况下,parent IAB节点在灵活资源上调度IAB MT,即与IAB DU传输无关。
可选的,当第二资源配置为UL资源(对应上述方案二),或者,第二资源配置和/或指示为灵活资源(对应上述方案五)且默认第二资源为UL资源时,上述在第一资源上执行第一操作可以包括以下至少一项:
当默认第一资源为UL或DL资源,且调度和/或配置IAB MT的DL传输在第一资源上时,IAB MT在第一资源上不进行接收;
当默认第一资源为UL或DL资源,且调度和/或配置IAB MT的UL传输在第一资源上时,IAB MT在第一资源上进行发送;
当没有调度和/或配置IAB MT的DL传输在第一资源上,且默认第一资源为UL资源时,IAB MT在第一资源上进行发送;
当没有调度和/或配置IAB MT的DL传输在第一资源上,且默认第一资源为灵活资源时,IAB MT在第一资源上不进行发送和接收;
当调度第一资源为灵活资源时,IAB MT在第一资源上不进行发送和接收;
IAB MT根据IAB节点的复用能力和/或预设规则,在第一资源上执行第一操作。比如,该预设规则可以包括以下至少一项:1)在默认MT UL和DU UL同时进行的情况下,IAB MT为UL发送,或者parent IAB节点调度IAB MT在灵活资源上为UL发送;2)在默认MT DL和DU UL同时进行的情况下,IAB MT为DL接收,或者parent IAB节点调度IAB MT在灵活资源上为DL接收;3)在默认IAB DU无传输的情况下,parent IAB节点在灵活资源上调度IAB MT,即与IAB DU传输无关。
可选的,IAB MT可以是在满足以下至少一项的情况下,在第一资源上执行第一操作:
IAB节点的传输根据DU传输和MT调度的优先级确定,或者,IAB节点的传输根据DU传输和MT调度的优先规则确定。比如,对于DU传输和MT调度的优先规则,可以是DU传输优先,也可以是MT调度优先。
在默认IAB DU存在传输的情况下,由parent IAB节点调度IAB MT。
可选的,当IAB DU无传输时,IAB MT的第一资源能够被parent IAB节点调度为UL资源、DL资源或者灵活资源。
可选的,上述在第二资源上执行第二操作可以包括以下至少一项:
IAB DU在所述第二资源上不进行发送和接收;
IAB DU根据IAB MT的调度,在第二资源上进行发送和/或接收。
可选的,在本申请实施例中,IAB MT的传输行为和IAB DU的传输行为可以与在IAB节点的传输中是IAB MT优先还是IAB DU优先相关。对于是IAB MT优先还是IAB DU优先,可以根据预设方法确定,比如预定义、预配置和/或配置是IAB MT优先或者IAB DU优先,也可以默认(或称为假设)IAB MT优先或者默认IAB DU优先。
例如,以第一资源和第二资源为symbol为例,在上述方案一下,即CU/parent IAB节点配置或指示IAB DU的部分资源为DL symbol,且parent IAB节点配置或指示该部分资源对应的IAB MT资源为flexible symbol:
(1)若预定义、预配置和/或配置了IAB DU优先,则满足以下至少一项:
1)默认IAB MT的资源为DL/UL,或者说,假设parent IAB节点调度IAB MT的资源为UL/DL。此时,以IAB DU的传输为准,保证IAB DU的传输,保证IAB节点半双工,干扰小。
可选的,若IAB MT接收到DCI调度,或高层配置IAB MT的UL传输在对应flexible symbol上,则IAB MT不发送信息。
可选的,若IAB MT接收到DCI调度,或高层配置IAB MT的DL传输在对应flexible symbol上,则IAB MT在对应flexible symbol上接收信息。
2)若IAB MT未收到(有效的)DCI指示/高层配置的IAB MT为UL调度时,则假设IAB MT的资源为DL或者flexible。这里没有区分高层信令/物理层信令的区别,认为所有信令都应该遵守。
可选的,若默认对应flexible symbol为DL,则IAB MT的传输行为同上述1)中所示。
可选的,若默认对应的symbol为flexible,则IAB MT在对应的symbol上不发送也不接收。
3)若DCI指示IAB MT的符号为flexible,则默认IAB MT在该符号上不发送也不接收。也就是,至少DU资源类型配置允许DU传输的情况下,IAB节点不期望parent IAB节点调度MT。此IAB MT在flexible symbol上不发送也不接收,相当于把DCI指示的flexible symbol作为MT方面的NA的作用,保证DU的传输。
4)可选的,满足以下至少一项时,采用上述1)-3)中的默认/假设:
IAB节点的传输根据DU传输和MT调度的优先级确定,或者,IAB节点的传输根据DU传输和MT调度的优先规则确定;
在默认IAB DU存在传输的情况下,由parent IAB节点调度IAB MT。
5)若parent IAB节点提前获取DU无传输,则parent IAB节点可以调度IAB MT的flexible symbol为UL/DL/flexible。其中,DU无传输的信息可以是DU上报给parent IAB节点。
(2)若预定义、预配置和/或配置了IAB MT优先,则:
1)IAB DU的行为满足以下至少一项:
a)IAB DU在对应的symbol上不进行发送和接收。即,无论DU资源 类型配置是否允许IAB DU传输,IAB DU在对应的symbol上不进行发送和接收。
b)IAB DU根据IAB MT的调度,在对应的symbol上进行发送和/或接收。即,如果DU资源类型配置允许DU调度,IAB DU采取保守的方式调度,parent IAB节点调度MT时具有一定的调度激进性。
比如,IAB DU默认parent IAB节点可以做任意UL/DL调度;IAB DU不能确定IAB MT的flexible symbol有无调度,和/或IAB DU不能确定IAB MT的flexible symbol调度为UL还是为DL。这种情况下,可能只有IAB节点支持全双工的情况下,才能进行调度,否则大概率是不能调度。又比如,IAB DU能够确定IAB MT的flexible symbol有无调度,和/或确定IAB MT的flexible symbol调度为UL还是为DL的情况下,IAB DU根据IAB MT的调度方进行传输。
2)IAB MT根据IAB节点的复用能力或者默认的规则,确定IAB MT的传输方向,满足以下至少之一:
a)在默认MT UL和DU DL同时进行的情况下,IAB MT为UL发送,或者parent IAB节点调度IAB MT在flexible symbol上为UL发送;
b)在默认MT DL和DU DL同时进行的情况下,IAB MT为DL接收,或者parent IAB节点调度IAB MT在flexible symbol上为DL接收;
c)在默认IAB DU无传输的情况下,parent IAB节点在flexible symbol上调度IAB MT,即与IAB DU传输无关。
又例如,以第一资源和第二资源为symbol为例,在上述方案二下,即CU/parent IAB节点配置或指示IAB DU的部分资源为UL symbol,且parent IAB节点配置或指示该部分资源对应的IAB MT资源为flexible symbol:
(1)若预定义、预配置和/或配置了IAB DU优先,则满足以下至少一项:
1)默认IAB MT的资源为UL/DL。
可选的,若IAB MT接收到DCI调度,或高层配置IAB MT的DL传输在对应flexible symbol上,则IAB MT不接收信息。
可选的,若IAB MT接收到DCI调度,或高层配置IAB MT的UL传输在对应flexible symbol上,则IAB MT在对应flexible symbol上发送信息。
需指出的,对于默认IAB MT的资源为DL,是考虑IAB MT需要监听PDCCH,在发送UL信息,或者监听PDCCH接收DL信息。在未收到调度信息时,可能是需要先监听PDCCH的。
2)若IAB MT未收到(有效的)DCI指示/高层配置的IAB MT为DL调度时,则IAB MT的资源为UL或者flexible。
可选的,若默认对应flexible symbol为UL,则IAB MT的传输行为同上述1)中所示。
可选的,若默认对应flexible symbol为flexible,则IAB MT在对应的symbol上不发送也不接收。
3)若DCI指示IAB MT的符号为flexible,则默认IAB MT在该符号上不发送也不接收。也就是,IAB节点不期望parent IAB节点调度MT,至少DU资源类型配置允许DU传输的情况下。
4)可选的,满足以下至少一项时,采用上述1)-3)中的默认/假设:
IAB节点的传输根据DU传输和MT调度的优先级确定,或者,IAB节点的传输根据DU传输和MT调度的优先规则确定;
在默认IAB DU存在传输的情况下,由parent IAB节点调度IAB MT。
5)若parent IAB节点提前获取DU无传输,则parent IAB节点可以调度IAB MT的flexible symbol为UL/DL/flexible。其中,DU无传输的信息可以是DU上报给parent IAB节点。
(2)若预定义、预配置和/或配置了IAB MT优先,则:
1)IAB DU的行为满足以下至少一项:
a)IAB DU在对应的symbol上不进行发送和接收。即,无论DU资源类型配置是否允许IAB DU传输,IAB DU在对应的symbol上不进行发送和接收。
b)IAB DU根据IAB MT的调度,在对应的symbol上进行发送和/或接收。即,如果DU资源类型配置允许DU调度,IAB DU采取保守的方式调度,parent IAB节点调度MT时具有一定的调度激进性。
比如,IAB DU默认parent IAB节点可以做任意UL/DL调度;IAB DU不能确定IAB MT的flexible symbol有无调度,和/或IAB DU不能确定IAB  MT的flexible symbol调度为UL还是为DL。这种情况下,可能只有IAB节点支持全双工的情况下,才能进行调度,否则大概率是不能调度。又比如,IAB DU能够确定IAB MT的flexible symbol有无调度,和/或确定IAB MT的flexible symbol调度为UL还是为DL的情况下,IAB DU根据IAB MT的调度方进行传输。
2)IAB MT根据IAB节点的复用能力或者默认的规则,确定IAB MT的传输方向,满足以下至少之一:
a)在默认MT UL和DU UL同时进行的情况下,IAB MT为UL发送,或者parent IAB节点调度IAB MT在灵活资源上为UL发送;
b)在默认MT DL和DU UL同时进行的情况下,IAB MT为DL接收,或者parent IAB节点调度IAB MT在灵活资源上为DL接收;
c)在默认IAB DU无传输的情况下,parent IAB节点在灵活资源上调度IAB MT,即与IAB DU传输无关。
本申请实施例中,IAB节点可以从parent IAB节点接收调度信令,比如IAB MT的调度信令。IAB MT的调度信令可以由parent IAB节点根据IAB节点的上报内容和/或IAB DU的实际调度等确定。进一步的,IAB DU根据IAB MT的调度信令,可以确定IAB MT的传输方向,即判断IAB MT的资源为UL/DL/flexible。
可选的,IAB MT的调度信令可以满足以下至少一项:
1)当IAB MT的调度信令的传输时间比IAB DU的传输时间早M个时间单元时,IAB MT的调度信令为有效的信令。
其中,M为大于或等于0的整数。M、M的最大值和/或M的最小值可以是以下至少一项:预定义的参数、预配置的参数、高层配置的参数、parent IAB节点指示的参数。上述时间单元包括但不限于:符号,时隙,帧,微秒,毫秒,秒等。
2)IAB DU以最新收到的有效的IAB MT的调度为生效的调度。
3)IAB MT的调度的生效时长、生效时长的最大值或生效时长的最小值为以下至少一项:预定义的参数、预配置的参数、高层配置的参数、parent IAB节点指示的参数。
4)IAB MT的调度的生效时间与IAB MT和IAB DU的复用方式的应用时间对应。其中,IAB MT和IAB DU的复用方式可以是半静态/动态配置的复用方式。
本申请实施例中,IAB MT和IAB DU的同发/同收/一发一收的四种复用方式可以不应用于IAB DU配置为flexible symbol的时域资源,或者根据指示确定是否应用于IAB节点。
可选的,IAB节点可以确定IAB MT和IAB DU的复用方式不应用于IAB DU的配置和/或指示为灵活资源的资源。和/或,IAB节点可以根据parent IAB节点和/或donor IAB节点的指示,确定IAB MT和IAB DU的复用方式应用于或不应用于IAB DU的配置和/或指示为灵活资源的资源。比如,parent IAB节点可以通过F1-AP/高层配置/DCI,指示同发/同收的复用方式不应用于或者应用于IAB DU的配置和/或指示为灵活资源的资源。例如,可以采用Xbit(s)指示信息指示相应复用方式是否应用于IAB DU的配置和/或指示为flexible symbol的资源。
本申请实施例中,IAB MT和IAB DU的复用方式可以半静态/动态配置。当IAB MT和IAB DU的复用方式应用于IAB节点时,IAB MT和IAB DU之间无优先级的关系,根据该复用方式确定的IAB节点的传输行为可以满足以下至少一项:
1)在第二资源配置和/或指示为DL资源(对应上述方案一),或者,第二资源配置和/或指示为灵活资源(对应上述方案五)且默认第二资源为DL资源,且默认IAB MT为UL传输的情况下,IAB节点的传输行为包括MT发送和DU发送。可选的,IAB MT可以在高层配置/DCI调度的UL传输的部分/全部资源上发送。
2)在第二资源配置和/或指示为DL资源(对应上述方案一),或者,第二资源配置和/或指示为灵活资源(对应上述方案五)且默认第二资源为DL资源,且默认IAB MT为DL传输的情况下,IAB节点的传输行为包括MT接收和DU发送。可选的,IAB MT可以在高层配置/DCI调度的DL传输的部分/全部资源上接收。
3)在第二资源配置和/或指示为UL资源(对应上述方案二),或者,第 二资源配置和/或指示为灵活资源(对应上述方案五)且默认第二资源为UL资源,且默认IAB MT为DL传输的情况下,IAB节点的传输行为包括MT接收和DU接收。可选的,IAB MT可以在高层配置/DCI调度的DL传输的部分/全部资源上接收。
4)在第二资源配置和/或指示为UL资源(对应上述方案二),或者,第二资源配置和/或指示为灵活资源(对应上述方案五)且默认第二资源为UL资源,且默认IAB MT为UL传输的情况下,IAB节点的传输行为包括MT发送和DU接收。可选的,IAB MT可以在高层配置/DCI调度的UL传输的部分/全部资源上发送。
可选的,本实施例中可以CU配置/parent IAB节点指示IAB MT和IAB DU的复用方式是否应用于IAB节点,也就是说是否使能上述1)至4)有关传输行为的规则。具体的,IAB节点可以从donor IAB节点接收第一配置信息,第一配置信息指示IAB MT和IAB DU的复用方式应用于或不应用于IAB节点。和/或,IAB节点可以从parent IAB节点接收指示信息,该指示信息指示IAB MT和IAB DU的复用方式应用于或不应用于IAB节点。
此外,IAB节点也可以上报其期待的复用方式,从而确定IAB MT和IAB DU的传输方向。
本申请实施例中,IAB节点可以默认/假设IAB MT的传输方向与DU的资源类型和/或DU的资源方向相关。对于MT配置/指示为灵活资源的资源即第一资源可以满足以下至少一项:
a)当第二资源配置为硬Hard资源时,IAB MT默认其在第一资源上的传输方向与IAB DU的传输方向相同。
例如,在上述方案一下,即第二资源配置和/或指示为DL资源,若IAB DU的资源类型为hard,则IAB MT为DL传输;或者,若DCI指示/高层信令调度IAB MT在相应资源上接收DL信息,比如PDSCH/PDCCH/CSI-RS/DL PRS等,则IAB MT在对应的位置接收信息。
又例如,在上述方案二下,即第二资源配置和/或指示为UL资源,若IAB DU的资源类型为hard,则IAB MT为UL传输;或者,若DCI指示/高层信令调度IAB MT在相应资源上发送UL信息,比如 PUCCH/PUSCH/PRACH/SRS等,则IAB MT在对应的位置发送信息。
b)当第二资源配置为软Soft资源时,IAB MT执行第三操作。
可选的,第三操作可以包括以下至少一项:
当调度和/或配置IAB MT在第一资源上发送时,IAB MT在第一资源上进行发送,也就是认为UL传输。比如,若DCI/高层调度IAB MT在对应符号上发送,则IAB MT在对应符号上发送。
当调度和/或配置IAB MT在第一资源上接收时,IAB MT在第一资源上进行接收,也就是认为DL传输。比如,若DCI/高层调度IAB MT在对应符号上接收,则IAB MT在对应符号上接收。
当配置IAB MT在第一资源上发送,且调度IAB MT在第一资源的部分或全部资源上接收时,IAB MT在第一资源上不进行发送,或者,IAB MT在第一资源的部分资源上进行发送,此可以参考SRS在部分符号上的发送。比如,若高层调度IAB MT在对应符号上发送,IAB MT检测到DCI调度其在部分/全部符号上接收,则IAB MT在对应符号上不进行发送,或者,IAB MT在部分符号上进行发送。
当配置IAB MT在第一资源上接收,且调度IAB MT在第一资源的部分或全部资源上发送时,在第一资源上不进行接收。比如,若高层调度IAB MT在对应符号上接收,IAB MT检测到DCI调度其在部分/全部符号上发送,则IAB MT在对应符号上不能接收。
c)当第二资源配置为不可用Not Available时,MT根据预设规则执行传输行为,即与现有传输行为一致,不需要考虑IAB DU的传输行为。
可选的,在本申请实施例中,IAB节点还可以从donor IAB节点接收第二配置信息,该第二配置信息用于指示IAB节点根据预设方法判断是IAB MT优先还是IAB DU优先。也就是说,donor IAB节点的CU可以配置IAB节点根据预设方法判断是IAB MT优先还是IAB DU优先。其中,当出现IAB节点复用限制时,可以限定IAB DU为下行传输。
可选的,上述根据预设方法判断是IAB MT优先还是IAB DU优先可以包括以下至少一项:
1)根据IAB节点的子链路(child link)和父链路(parent link)的业务 负荷差异,确定是IAB MT优先还是IAB DU优先。
比如,如果IAB节点的child link上的业务负荷/时延高于IAB节点的parent link上的业务负荷/时延,可以确定IAB DU优先于IAB MT使用资源;反之,IAB,MT优先于IAB DU使用资源。
2)根据IAB节点的子链路和父链路的拥塞状态,确定是IAB MT优先还是IAB DU优先。
比如,如果IAB节点的child link上出现拥塞而IAB节点的parent link上未出现拥塞,则IAB DU优先使用资源,反之,则IAB MT优先使用资源。
3)根据IAB节点的子链路和父链路的逻辑信道优先级,确定是IAB MT优先还是IAB DU优先。
比如,如果IAB节点的child link上的待传输数据的优先级高于IAB节点的parent link上的待传输数据的优先级,则IAB DU优先使用资源,反之,则IAB MT优先使用资源。
可选的,CU可以配置使用或者不使用上述1)至3)中方法的一种或者多种。具体的,IAB节点可以从donor IAB节点接收第三配置信息,该第三配置信息用于指示IAB节点使用或者不使用预设方法判断是IAB MT优先还是IAB DU优先。
可选的,IAB节点可以向CU请求配置上述1)至3)中方法的一种或者多种。具体的,IAB节点向donor IAB节点发送请求信息,该请求信息用于请求donor IAB节点配置预设方法,此预设方法用于判断是IAB MT优先还是IAB DU优先。
