Description

用于无线通信的电子设备和方法、计算机可读存储介质
本申请要求于2020年5月11日提交中国专利局、申请号为202010392038.3、发明名称为“用于无线通信的电子设备和方法、计算机可读存储介质”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域,具体地涉及一种波束失败恢复机制。更具体地,涉及一种用于无线通信的电子设备和方法以及计算机可读存储介质。
背景技术
在Rel-15中的波束失败恢复(Beam Failure Recovery,BFR)流程中,定义了一组用于波束失败检测的周期性信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)资源索引集合
Figure PCTCN2021091848-appb-000001
集合
Figure PCTCN2021091848-appb-000002
中最多包含两个参考信号的索引值。并且,在波束失败检测流程中已经达成共识,当集合
Figure PCTCN2021091848-appb-000003
中与所有波束失败检测参考信号(Beam Failure Detecting Reference Signal,BFD-RS)相对应的块差错率(Block Error Rate,BLER)值都大于阈值时,UE将判定发生波束失败事件。由于Rel-15中的BFR流程是针对单个发送和接收点(Transceiving and Receiving Point,TRP)的场景,尽管集合
Figure PCTCN2021091848-appb-000004
中包含两个BFD-RS,但实际上与该参考信号对应的两个波束的方向通常是相同的。当其中一个波束发生波束失败时,另一个波束也会发生波束失败。
然而,当考虑Multi-TRP场景时,由于多个TRP的位置不同,因此它们的参考信号对应的波束方向也不同。可能存在其中一个TRP发生波束失败,而其他TRP运行良好的情形。鉴于此,对于多TRP场景,应该应用不同的BFR策略。

在此,还需要说明的一点是,为了避免因不必要的细节而模糊了本发明,在附图中仅仅示出了与根据本发明的方案密切相关的设备结构和/或处理步骤,而省略了与本发明关系不大的其他细节。
<第一实施例>
图1示出了根据本申请的一个实施例的用于无线通信的电子设备100的功能模块框图,如图1所示,电子设备100包括:获取单元101,被配置为从基站获取用于多TRP通信中用户设备(User Equipment,UE)的BFR的配置信息,其中,配置信息包括第一配置和/或第二配置,第一配置用于多个TRP中的每一个TRP的波束失败事件的判定,第二配 置用于多个TRP的波束失败事件的联合判定;以及报告单元102,被配置为基于配置信息向基站报告波束失败事件。
其中,获取单元101和报告单元102可以由一个或多个处理电路实现,该处理电路例如可以实现为芯片。并且,应该理解,图1中所示的装置中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块,而不是用于限制具体的实现方式。
电子设备100例如可以设置在用户设备(UE)侧或者可通信地连接到UE。这里,还应指出,电子设备100可以以芯片级来实现,或者也可以以设备级来实现。例如,电子设备100可以工作为用户设备本身,并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储用户设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如,基站、其他用户设备等等)间的通信,这里不具体限制收发器的实现形式。这同样适用于随后关于用户设备侧的电子设备的其他配置示例的描述。
此外,应该注意,本文中的第一、第二、……仅是为了区分的目的,而不存在任何顺序上的含义。
UE侧执行的BFR机制例如可以包括波束失败确定、候选波束识别、波束失败恢复请求(Beam Failure Recovery Request,BFRQ)发送和波束失败恢复请求响应(Beam Failure Recovery Request Response,BFRR)获取几个阶段。其中,在波束失败确定阶段,UE对当前服务波束的波束质量进行检测以判断是否满足波束失败触发条件,例如可以将服务波束的BLER与BLER阈值进行比较来判断是否发生波束失败;在候选波束识别阶段,从其他波束中选择可以用作当前服务波束的替选的候选波束;在BFRQ发送阶段,向基站(例如gNB)发送BFRQ;在BFRR获取阶段,UE在特定时间窗内监视来自基站的对BFRQ的响应BFRR。
如前所述,在多TRP场景中,存在一个TRP发生波束失败,而其他TRP正常工作的情况。图2a和图2b示出了多TRP场景中波束失败的情形的示例,图2a中只有TRP 0发生波束失败,而图2b中TRP 0和TRP 1均发生了波束失败。
根据现有的BFR机制,在只有一个TRP发生波束失败的情况下UE不会向基站上报波束失败事件。而在多TRP场景中,如果不进行波束失 败恢复,可能会影响UE的性能。此外,由于多TRP进行了联合传输,因此可能存在多个TRP均发生了波束失败但是UE的传输性能仍然可以接受的情形。为了提供一种适合于多TRP场景的BFR机制,本实施例提供了第一配置和第二配置,以分别针对每个TRP进行波束失败判定和针对多个TRP进行联合的波束失败判定。
获取单元101从基站获取第一配置和/或第二配置,例如,获取单元101可以经由无线资源控制(RRC)信令来获取配置信息。
下面将具体描述第一配置和第二配置的示例。如图3所示,电子设备100还包括:判定单元103,被配置为基于配置信息进行波束失败事件的判定。判定单元103例如也可以实现为处理电路。
例如,第一配置包括如下中的一个或多个:针对每一个TRP的BLER阈值,对每一个TRP的物理层波束失败次数进行计数的第一计数器,以及该第一计数器的第一最大计数阈值。其中,判定单元103被配置为响应于第一配置,在多个TRP中的一个TRP发生物理层波束失败时,使该TRP的第一计数器加1,并且在第一计数器的计数值达到第一最大计数阈值时,确定该TRP发生波束失败事件,报告单元102将该波束失败事件报告给基站。例如,当一个TRP的BLER高于该TRP的BLER阈值时,判定单元103确定该TRP发生物理层波束失败,即,产生了一个波束失败事件的实例,UE向自己的高层报告该波束失败事件。例如,判定单元103可以检测每一个TRP所配置的波束失败探测参考信号(BFD-RS)的BLER作为TRP的BLER。其中,该检测可以是周期性的。
可以看出,根据第一配置,当部分TRP的波束发生波束失败事件时,将进行上报并触发BFR流程。因此,可以尽快恢复失败的波束,保证传输的可靠性。在判定单元103确定多于一个TRP发生波束失败事件的情况下,报告单元102分别向基站报告这多于一个TRP的波束失败事件。针对不同的TRP的波束失败事件的上报是相互独立的。
为了便于理解,下面将以两个TRP(TRP 0和TRP 1)的场景为例进行描述,每个TRP配置有一个参考信号(即,对应于一个波束)。在这样的示例中,分别为TRP 0和TRP 1配置BLER阈值BLER 0和BLER 1。例如,在某一时刻检测到TRP 0的BLER大于BLER 0时,认为发生了物 理层波束失败事件,启动TRP 0的第一计数器并加1,后续每检测到一次TRP 0的BLER大于BLER 0,则将TRP 0的第一计数器加1。类似地,在某一时刻检测到TRP 1的BLER大于BLER 1时,认为发生了物理层波束失败事件,启动TRP 1的第一计数器并加1,后续每检测到一次TRP 1的BLER大于BLER 1,则将TRP 1的第一计数器加1。TRP 0和TRP 1的第一计数器分别独立计数,并且在相应的第一计数器的计数超过第一最大计数阈值时认为对应的TRP发生波束失败事件。
其中,各个TRP的BLER阈值可以相同,也可以不同。各个TRP的第一计数器的第一最大计数阈值也可以相同或者不同。这些都可以由基站进行配置。
应该理解,根据现有的标准,BFD-RS集合中配置了两个参考信号,在多TRP的场景中,可以为一个TRP配置一个参考信号(如上述示例中所述)。但是本申请并不限于此,也可以适用于一个TRP配置有多个参考信号的情形,在这种情形下,例如,当一个TRP的所有参考信号对应的波束均发生物理层波束失败事件时,确定该TRP发生物理层波束失败事件。具体地,仍然针对每个TRP设置第一计数器,当一个TRP的所有参考信号对应的波束的BLER值均大于相应的BLER阈值时,认为该TRP发生了物理层波束失败事件,该TRP的第一计数器加1。如果只是一部分参考信号对应的波束的BLER值超过相应的BLER阈值,TRP的第一计数器不累加1。并且,当一个TRP的第一计数器达到第一最大计数阈值时,认为该TRP发生了波束失败事件。
替选地,可以为每一个TRP的每一个波束设置第一计数器,并且,对于一个TRP的多个波束,可以配置相同的BLER阈值,也可以配置不同的BLER阈值。当一个波束的第一计数器达到第一最大计数阈值时,认为该波束发生了波束失败事件,并且当一个TRP的所有波束的第一计数器均达到第一最大计数阈值时,认为该TRP发生了波束失败事件。
当然,也可以以另外的方式限定一个TRP的各个波束的波束失败事件与TRP的波束失败事件之间的关系。例如,可以对一个TRP的所有参考信号对应的波束的BLER进行平均,并将该平均BLER作为TRP的BLER来进行TRP是否发生波束失败事件的判断。
另一方面,例如,第二配置可以包括如下中的一个或多个:用于计 算多个TRP的联合BLER的加权参数,联合BLER的阈值,对多个BLER的联合物理层波束失败次数进行计数的第二计数器,以及该第二计数器的第二最大计数阈值。所述判定单元103被配置为响应于第二配置,在多个TRP发生联合物理层波束失败事件时,使第二计数器加1,并且在第二计数器的计数值达到第二最大计数阈值时,确定多个TRP发生联合波束失败事件,报告单元102将该联合波束失败事件报告给基站。例如,当多个TRP的联合BLER高于联合BLER阈值时,判定单元103确定多个TRP发生联合物理层波束失败,即,产生了一个联合波束失败事件的实例。UE将该联合波束失败事件的实例报告给自己的上层。
当联合波束失败事件的实例的数目超过第二最大计数阈值时,判定单元103确定相应的TRP发生联合波束失败事件。报告单元102向基站进行上报,以触发BFR流程。
根据第二配置,基于多个TRP的联合BLER来进行波束失败事件的判定。由于在多TRP场景中,UE的性能是基于多个TRP的联合传输性能决定的,因此基于联合BLER的波束失败判定能够准确地反映UE的性能的劣化,提高可靠性。
例如,判定单元103可以根据加权参数对多个TRP中的每一个TRP的BLER进行加权求和,并将结果作为联合BLER。加权参数针对每一个TRP设置,并且可以为0至1范围内的常数,所有加权参数之和为1。
为了便于理解,仍然以两个TRP(TRP 0和TRP 1)的场景为例进行描述,每个TRP配置有一个参考信号(即,对应于一个波束)。在这样的示例中,联合BLER由两个TRP的BLER加权求和得到,加权参数由第二配置得到,例如,可以通过下式(1)来计算联合BLER。
BLER joint=w 0BLER 0+w 1BLER 1   (1)
其中,BLER 0为TRP 0的BLER,BLER 1为TRP 1的BLER,w 0和w 1分别为对应于TRP 0和TRP 1的加权参数,BLER joint为计算得到的联合BLER。当BLER joint高于联合BLER阈值,认为发生了联合物理层波束失败事件,即,产生了一个联合波束失败事件的实例。第二计数器对该实例的个数进行计数,当计数值达到第二最大计数阈值时,判定单元103确定发生了联合波束失败事件。
类似地,本实施例也可以适用于一个TRP配置有多个参考信号的情 形,在这种情形下,例如,对于一个TRP的多个波束,分别设置其加权参数,并且对所有TRP的所有波束的BLER进行加权求和,当最终得到的BLER超过联合BLER阈值时,认为发生了联合物理层波束失败事件,即,产生了一个联合波束失败事件的实例。当然,也可以对同一个TRP的多个波束设置相同的加权参数,这都不是限制性的。
UE可以以第一配置和第二配置之一进行操作,也可以通过将第一配置和第二配置结合来进行操作。在前一种情况下,获取单元101可以仅从基站获取第一配置和第二配置之一的信息。
在后一种情况下,即同时配置了第一配置和第二配置的情况,获取单元101可以获取第一配置和第二配置两者的信息。换言之,获取单元101可以获取如下中的一个或多个:针对每一个TRP的BLER阈值,对每一个TRP的物理层波束失败次数进行计数的第一计数器,该第一计数器的第一最大计数阈值,用于计算多个TRP的联合BLER的加权参数,联合BLER的阈值,对多个BLER的联合物理层波束失败次数进行计数的第二计数器,以及该第二计数器的第二最大计数阈值。
判定单元103可以被配置为响应于第一配置和第二配置执行如下操作:在多个TRP中的一个TRP发生物理层波束失败时,使该TRP的第一计数器加1;在多个TRP发生联合物理层波束失败时,使第二计数器加1;以及在多个第一计数器中的任意一个的计数值先达到第一最大计数阈值时,确定与该第一计数器对应的TRP发生波束失败事件并向基站进行报告,在第二计数器的计数值先达到第二最大计数阈值时,确定多个TRP发生联合波束失败事件并向基站进行报告。例如,在多个TRP中的一个TRP的BLER高于BLER阈值时,认为该TRP发生物理层波束失败;在多个TRP的联合BLER高于联合BLER阈值时,认为多个TRP发生联合物理层波束失败。
可以看出,在这种情况下,使用第二计数器和多个第一计数器分别对联合波束失败的实例和各个TRP的波束失败的实例进行计数,并且在任何一个计数器达到其阈值时,向基站报告相应的波束失败事件。即,无论是发生单独的TRP的波束失败事件还是联合的波束失败事件,报告单元102均向基站发送报告,以触发BFR流程。这样可以进一步提高传输的可靠性,降低时延。
下面仍然通过两个TRP(TRP 0和TRP 1)的场景为例进行描述,每个TRP配置有一个参考信号(即,对应于一个波束)。此时,将配置有两个第一计数器和一个第二计数器,分别对TRP 0、TRP 1的波束失败事件的实例和联合波束失败事件的实例进行计数。这三个计数器独立工作,在下文中分别记作Counter_0、Counter_1和Counter_m,其相应的最大计数阈值为MaxCount_Num_0、MaxCount_Num_1和MaxCount_Num_m。
图4示出了检测到的BLER随时间的变化的一个示例。其中,横轴为时间轴,纵轴为检测到的BLER,虚线代表TRP 0的BLER(BLER 0),实线代表TRP 1的BLER(BLER 1),点划线代表联合BLER(BLER joint),纵轴上的BLER_m代表联合BLER阈值,BLER_s代表针对TRP 0和TRP 1的BLER阈值。在该示例中,针对两个TRP的BLER阈值是相同的,但是这并不是限制性的,二者也可以不同。
如图4所示,由于检测到的BLER未超过其相应的阈值,因此三个计数器未启动计数,判定单元103不会判定发生波束失败事件,因此不会触发BFR流程。
图5示出了检测到的BLER随时间的变化的另一个示例。其中,坐标和各条曲线的含义与图4中的相同,在此不再重复。如图5所示,在A点处检测到的BLER 0超过了阈值BLER_s,因此TRP 0发生了物理层波束失败,计数器Counter_0启动并计数增加1。在B点处,假设计数器Counter_0的计数值达到了其第一最大计数阈值MaxCount_Num_0(图中的Count_Num_0代表计数器Counter_0的当前值),此时确定TRP 0发生了波束失败事件,并触发BFR流程。因此,在图5的示例中,为了确保传输的可靠性,无论联合传输性能如何,UE都会尽快恢复发生波束失败的TRP。
图6示出了检测到的BLER随时间的变化的另一个示例。其中,坐标和各条曲线的含义与图4中的相同,在此不再重复。如图6所示,在A点处检测到联合BLER超过阈值BLER_m,即,发生了联合物理层波束失败,计数器Counter_m启动并计数增加1。在B点处,假设计数器Counter_m的计数值达到了第二最大计数阈值MaxCount_Num_m,此时确定发生了联合波束失败事件,触发BFR流程。注意,在图6的示例中,假设与多个TRP对应的计数器Counter_m比与单个TRP对应的计 数器Counter_0和Counter_1先达到其最大计数阈值。因此,在图6的示例中,当联合传输性能较差时,无论单个TRP的性能如何,UE都会尽快执行BFR流程,以确保传输的可靠性。
在5G通信中,定义了三大主要传输场景类型:增强型移动带宽(enhanced Mobile Broadband,eMBB),超可靠低延时通信(Ultra Reliable Low Latnecy Communications,URLLC),大规模机器类通信(massive Machine Type Communications,mTTC)。eMBB可以提供高流量移动带宽服务,URLLC提供低延时高可靠服务。例如,在多TRP场景下,针对eMBB,可以使得不同TRP传输不同的传输块来提高传输速率;针对URLLC,可以使得不同TRP传输相同的传输块来减小传输时延和增加可靠性。
因此,针对eMBB,由于不同TRP传输不同的传输块,因此即使当发生部分波束失败时,也期望尽快恢复失败的波束,例如可以采用第一配置。针对URLLC场景,由于不同TRP传输相同的传输块,因此可以基于多个TRP的联合传输性能来确定是否需要执行BFR,此外,如果一个TRP发生波束失败事件,则立刻执行BFR,将进一步提高传输的可靠性,因此可以采用第二配置或者第一配置和第二配置的结合。
换言之,UE采用哪种波束失败恢复的配置可以根据传输场景类型来确定。在一个示例中,由基站来确定传输场景类型,并根据该传输场景类型来为UE提供相应的波束失败恢复的配置。例如,在eMBB场景下,基站向UE提供第一配置,即,获取单元101所获取的配置信息包括第一配置;在URLLC场景下,基站向UE提供第一配置和第二配置,即,获取单元101所获取的配置信息包括第一配置和第二配置;在URLLC场景下,基站向UE提供第二配置,即,获取单元101所获取的配置信息包括第二配置,等等。
在另一个示例中,配置信息中还包括指示传输场景类型的信息,传输场景类型包括eMBB和URLLC之一。判定单元103被配置为根据所指示的传输场景类型,来确定基于第一配置和/或基于第二配置进行波束失败事件的报告。类似地,例如,在eMBB场景下,基于第一配置进行波束失败事件的报告;在URLLC场景下,基于第二配置或者基于第一配置和第二配置进行波束失败事件的报告。
如前所述,BFR流程还包括新的候选波束的识别和BFRQ的发送。本实施例针对多TPR场景提出了BFRQ的发送的新的方式。
例如,报告单元102被配置为通过链路恢复请求(Link Recovery Request,LRR)来向基站报告波束失败事件。其中,LRR是一种特殊的物理层消息,由物理上行控制信道(PUCCH)承载,用于UE向网络侧请求上行链路授权(UL grant),以便UE可以发送物理上行共享信道(PUSCH)。因此,LRR是可以在任意时刻被UE触发的信息,通过LRR来报告波束失败事件可以保证报告的及时性。
在一个示例中,LRR可以具有特定的序列格式,以指示发生了波束失败事件。该特定的序列格式例如可以为全0序列或全1序列。在这种情况下,报告单元102还被配置为通过MAC CE向基站发送指示发生波束失败事件的TRP的信息以及发生波束失败事件的TRP的候选波束的信息。即,BFRQ的发送包括两个步骤:一是发送指示波束失败事件发生的特殊序列LRR;二是发送指示所涉及TRP和相应的候选波束的信息的MAC CE。MAC CE例如承载在PUSCH资源上。
其中,可以用控制资源集合池索引(CORESETPoolIndex)来指示发生波束失败事件的TRP。CORESETPoolIndex是针对多TRP场景提出的概念,被配置在控制资源集合上,用于区分具有同一小区ID的不同TRP。在多TRP场景中,Rel-16中的BFRQ的第二步流程中上报的Scell的索引是不必要的,因此可以复用这些比特来发送发生波束失败事件的TRP的CORESETPoolIndex。
例如,在发生联合波束失败的情况下,报告单元102可以首先向基站发送全0或全1的特殊序列,然后将TRP 0和TRP 1对应的两个CORESETPoolIndex和各自的候选波束的信息发送给基站。
在另一个示例中,LRR可以包括指示发生波束失败事件的TRP的信息。例如,可以用CORESETPoolIndex来指示发生波束失败事件的TRP。报告单元102还被配置为通过MAC CE来向基站发送波束失败事件的TRP的候选波束的信息。
可以看出,在该示例中,BFRQ的发送也包括两个步骤:一是指示发生波束失败事件的TRP的信息(LRR);二是所涉及的TRP的候选波束的信息(MAC CE)。其中,指示发生波束失败事件的TRP的信息通 过PUCCH发送,候选波束的信息通过PUSCH发送。
例如,在仅有TRP 0发生波束失败事件的情况下,报告单元102首先将TRP 0对应的CORESETPoolIndex(例如,0)承载在LRR中发送至基站,然后将TRP 0的候选波束的信息承载在MAC CE上发送给基站。
综上所述,根据本实施例的电子设备100提供了针对多TRP场景下的波束失败判定的准则和波束失败事件的通知机制,能够更好地保障多TRP场景下传输的可靠性以及减小时延。
<第二实施例>
图7示出了根据本申请的另一个实施例的电子设备200的功能模块框图,如图7所示,电子设备200包括:发送单元201,被配置为向UE发送用于多TRP通信中UE的波束失败恢复的配置信息,其中,配置信息包括第一配置和/或第二配置,第一配置用于多个TRP中的每一个TRP的波束失败事件的判定,第二配置用于多个TRP的波束失败事件的联合判定;以及获取单元202,被配置为从UE获取UE基于配置信息对波束失败事件的上报。
其中,发送单元201和获取单元202可以由一个或多个处理电路实现,该处理电路例如可以实现为芯片。并且,应该理解,图7中所示的装置中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块,而不是用于限制具体的实现方式。
电子设备200例如可以设置在基站侧或者可通信地连接到基站。这里,还应指出,电子设备200可以以芯片级来实现,或者也可以以设备级来实现。例如,电子设备200可以工作为基站本身,并且还可以包括诸如存储器、收发器(未示出)等外部设备。存储器可以用于存储基站实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如,用户设备、其他基站等等)间的通信,这里不具体限制收发器的实现形式。
如前所述,在多TRP场景中,存在一个TRP发生波束失败,而其他TRP正常工作的情况。根据现有的BFR机制,在只有一个TRP发生波束失败的情况下UE不会向基站上报波束失败事件。而在多TRP场景 中,如果不进行波束失败恢复,则可能会影响UE的性能。此外,由于多TRP进行了联合传输,因此可能存在多个TRP均发生了波束失败但是UE的传输性能仍然可以接受的情形。因此,针对多TRP场景,提供了第一配置和第二配置,以分别针对每个TRP进行波束失败判定和针对多个TRP进行联合的波束失败判定。
发送单元201向UE发送第一配置和/或第二配置,例如,发送单元201可以经由RRC信令来发送这些信息,以使得UE基于第一配置和/或第二配置进行波束失败事件的判定和BFR流程的触发。
例如,第一配置包括如下中的一个或多个:针对每一个TRP的BLER阈值,对每一个TRP的物理层波束失败次数进行计数的第一计数器,以及该第一计数器的第一最大计数阈值。例如,各个TRP的BLER阈值可以相同或者不同,各个TRP的第一计数器的第一最大计数阈值可以相同或者不同。
根据第一配置,UE分别针对每个TRP执行波束失败事件的确定和报告,从而可以执行部分波束失败恢复。UE侧的具体的操作在第一实施例中已经详细给出,在此不再重复。
例如,在多于一个TRP发生波束失败事件的情况下,获取单元202从UE获取对多于一个TRP的波束失败事件的报告。针对不同的TRP的波束失败事件的上报是相互独立的。
应该理解,在一个TRP配置有多个参考信号的情形中,如果该TRP的所有参考信号对应的波束均发生物理层波束失败事件时,则确定该TRP发生物理层波束失败事件。具体地,仍然针对每个TRP设置第一计数器,当一个TRP的所有参考信号对应的波束的BLER值均大于相应的BLER阈值时,认为该TRP发生了物理层波束失败事件,该TRP的第一计数器加1。如果只是一部分参考信号对应的波束的BLER值超过相应的BLER阈值,TRP的第一计数器不累加1。并且,当一个TRP的第一计数器达到第一最大计数阈值时,认为该TRP发生了波束失败事件。
此外,如第一实施例中所述,也可以为每一个TRP的每一个波束设置第一计数器,并且,对于一个TRP的多个波束,可以配置相同的BLER阈值,也可以配置不同的BLER阈值。例如,当一个TRP的所有波束均发生波束失败事件时,认为该TRP发生了波束失败事件。或者,也可以 以另外的方式限定一个TRP的各个波束的波束失败事件与TRP的波束失败事件之间的关系。例如,UE可以对一个TRP的所有参考信号对应的波束的BLER进行平均,并将该平均BLER作为TRP的BLER来进行TRP是否发生波束失败事件的判断。
另一方面,例如,第二配置可以包括如下中的一个或多个:用于计算多个TRP的联合BLER的加权参数,联合BLER的阈值,对多个BLER的联合物理层波束失败次数进行计数的第二计数器,以及该第二计数器的第二最大计数阈值。
根据第二配置,UE基于多个TRP的联合BLER来进行波束失败事件的判定。由于在多TRP场景中,UE的性能是基于多个TRP的联合传输性能决定的,因此基于联合BLER的波束失败判定能够准确地反映UE的性能的劣化,提高可靠性。
类似地,对于一个TRP配置有多个参考信号的情形,可以分别设置针对各个参考信号对应的波束的BLER的加权参数。UE对所有TRP的所有波束的BLER进行加权求和,当最终得到的BLER超过联合BLER阈值时,认为发生了联合物理层波束失败事件,即,产生了一个联合波束失败事件的实例。
示例性地,基站可以配置UE以第一配置和第二配置之一进行操作,也可以配置UE以第一配置和第二配置结合的方式进行操作。
在一个示例中,基站可以确定传输场景类型,并根据该传输场景类型来为UE提供相应的波束失败恢复的配置,即提供第一配置和第二配置之一,或者提供第一配置和第二配置两者。例如,在eMBB场景下,基站向UE提供第一配置,即,发送单元201所发送的配置信息包括第一配置;在URLLC场景下,基站向UE提供第一配置和第二配置,即,发送单元201所发送的配置信息包括第一配置和第二配置;在URLLC场景下,基站向UE提供第二配置,即,发送单元201所发送的配置信息包括第二配置,等等。
在另一个示例中,配置信息中还包括指示传输场景类型的信息,传输场景类型包括eMBB和URLLC之一。UE根据该传输场景类型的信息确定要使用的配置。
此外,获取单元202被配置为通过LRR来获取UE的上报。在一个 示例中,LRR可以具有特定的序列格式,以指示发生了波束失败事件。该特定的序列格式例如可以为全0序列或全1序列。在这种情况下,获取单元202还被配置为通过MAC CE从UE获取指示发生波束失败事件的TRP的信息以及发生波束失败事件的TRP的候选波束的信息。
其中,可以用CORESETPoolIndex来指示发生波束失败事件的TRP。例如,在发生联合波束失败的情况下,获取单元202首先从UE接收到全0或全1的特殊序列,然后接收与TRP 0和TRP 1对应的两个CORESETPoolIndex和各自的候选波束的信息。
在另一个示例中,LRR可以包括指示发生波束失败事件的TRP的信息。例如,可以用CORESETPoolIndex来指示发生波束失败事件的TRP。获取单元202还被配置为通过MAC CE来从UE获取发生波束失败事件的TRP的候选波束的信息。其中,LRR承载在PUCCH上,MAC CE承载在PUSCH上。
例如,在仅有TRP 0发生波束失败事件的情况下,获取单元202首先从UE获取承载在LRR中的与TRP 0对应的CORESETPoolIndex(例如,0),然后获取承载在MAC CE上的TRP 0的候选波束的信息。
综上所述,根据本实施例的电子设备200提供了针对多TRP场景的波束失败判定的准则和波束失败事件的通知机制,能够更好地保障多TRP场景下传输的可靠性以及减小时延。
为了便于理解,图8示出了基站(gNodeB)与用户设备(UE)之间的针对多TRP场景的BFR机制的信息流程。如图8所示,首先,gNB例如通过RRC信令向基站发送用于BFR的配置信息,该配置信息中可以包括上述第一配置和/或第二配置,具体地,例如各种BLER阈值参数、计数器、计数器阈值参数等,此外,配置信息中还可以包括指示传输场景类型的信息。接着,UE例如根据配置信息所指示的相应的配置来进行波束质量的检测和波束失败事件的判定。当判定发生波束失败事件(单个TRP的波束失败事件或联合波束失败事件)时,UE在PUCCH上向基站发送LRR,LRR可以用来指示发生了波束失败事件,例如通过发送全0或全1的特殊序列来指示这一点。LRR还可以用来发送发生波束失败事件的TRP的信息比如所对应的CORESETPoolIndex。gNB在接收到LRR后,向UE发送上行链路授权,UE基于该上行链路授权在相应 的PUSCH资源上向基站发送MAC CE,MAC CE中可以包括发生波束失败事件的TRP的候选波束的信息。在LRR包括特殊序列的情况下,MAC CE中还可以包括发生波束失败事件的TRP的信息比如所对应的CORESETPoolIndex。
应该注意,图8中的信息流程仅是示意性的,并不对本申请构成限制。
<第三实施例>
在上文的实施方式中描述用于无线通信的电子设备的过程中,显然还公开了一些处理或方法。下文中,在不重复上文中已经讨论的一些细节的情况下给出这些方法的概要,但是应当注意,虽然这些方法在描述用于无线通信的电子设备的过程中公开,但是这些方法不一定采用所描述的那些部件或不一定由那些部件执行。例如,用于无线通信的电子设备的实施方式可以部分地或完全地使用硬件和/或固件来实现,而下面讨论的用于无线通信的方法可以完全由计算机可执行的程序来实现,尽管这些方法也可以采用用于无线通信的电子设备的硬件和/或固件。

上述方法包括:响应于第一配置,在多个TRP中的一个TRP发生物理层波束失败事件时,使该TRP的所述第一计数器加1,并且在第一计数器的计数值达到所述第一最大计数阈值时,确定该TRP发生波束失败事件并在步骤S12中向基站进行报告。其中,在确定多于一个TRP发生波束失败事件的情况下,分别向基站报告多于一个TRP的波束失败事件。
例如,第二配置包括如下中的一个或多个:用于计算多个TRP的联合BLER的加权参数,联合BLER阈值,对多个TRP的联合物理层波束失败次数进行计数的第二计数器,以及该第二计数器的第二最大计数阈值。例如,可以根据加权参数对多个TRP中的每一个TRP的BLER进行加权求和,并将结果作为联合BLER。示例性地,加权参数针对每一个TRP设置并且为0至1范围内的常数,所有加权参数之和为1。
上述方法包括:响应于第二配置,在多个TRP发生联合物理层波束失败事件时,使第二计数器加1,并且在第二计数器的计数值达到第二最大计数阈值时,确定多个TRP发生联合波束失败事件并在步骤S12中向基站进行报告。
此外,第一配置和第二配置还可以结合使用。上述方法包括:响应于第一配置和第二配置,在多个TRP中的一个TRP发生物理层波束失败事件时,使该TRP的所述第一计数器加1;在多个TRP发生联合物理层波束失败事件时,使第二计数器加1;以及在多个第一计数器中的任意一个的计数值先达到第一最大计数阈值时,确定与该第一计数器对应的TRP发生波束失败事件并向基站进行报告,在第二计数器的计数值先达到第二最大计数阈值时,确定多个TRP发生联合波束失败事件并向基站进行报告。
例如,在步骤S12中,可以通过LRR向基站报告所述波束失败事件。
在一个示例中,LRR可以具有特定的序列格式,以指示发生了波束失败事件。步骤S12还可以包括通过MAC CE向基站发送指示发生波束 失败事件的TRP的信息以及发生波束失败事件的TRP的候选波束的信息。其中,
在另一个示例中,LRR包括指示发生波束失败事件的TRP的信息。同样可以用CORESETPoolIndex来指示发生波束失败事件的TRP。步骤S12中还包括通过MAC CE向基站发送发生波束失败事件的TRP的候选波束的信息。
图10示出了根据本申请的另一个实施例的用于无线通信的方法的流程图,该方法包括:向UE发送用于多TRP通信中UE的波束失败恢复的配置信息(S21),其中,配置信息包括第一配置和/或第二配置,第一配置用于多个TRP中的每一个TRP的波束失败事件的判定,第二配置用于多个TRP的波束失败事件的联合判定;以及从UE获取UE基于该配置信息对波束失败事件的上报(S22)。该方法例如可以在基站侧执行。
示例性地,配置信息还可以包括指示传输场景类型的信息,传输场景类型包括增强型移动带宽和超可靠低时延通信之一。
类似地,第一配置可以包括如下中的一个或多个:针对每一个TRP的块差错率BLER阈值,对每一个TRP的物理层波束失败次数进行计数的第一计数器,以及该第一计数器的第一最大计数阈值。其中,各个TRP的BLER阈值可以相同或不同,以及/或者各个TRP的第一计数器的第一最大计数阈值相同或不同。
在多于一个TRP发生波束失败事件的情况下,从UE获取对多于一个TRP的波束失败事件的报告。
第二配置可以包括如下中的一个或多个:用于计算多个TRP的联合BLER的加权参数,联合BLER阈值,对多个TRP的联合物理层波束失败次数进行计数的第二计数器,以及该第二计数器的第二最大计数阈值。
在步骤S22中,可以通过LRR获取所述上报。在一个示例中,LRR具有特定的序列格式,以指示发生了波束失败事件。步骤S22还包括通过MAC CE从UE获取指示发生波束失败事件的TRP的信息以及发生波束失败事件的TRP的候选波束的信息。其中,发生波束失败事件的TRP可以用CORESETPoolIndex来指示。在另一个示例中,LRR可以包括指示发生波束失败事件的TRP的信息,比如发生波束失败事件的 TRP的CORESETPoolIndex。步骤S22还包括通过MAC CE从UE获取发生波束失败事件的TRP的候选波束的信息。
注意,上述各个方法可以结合或单独使用,其细节在第一至第二实施例中已经进行了详细描述,在此不再重复。

[关于基站的应用示例]
(第一应用示例)
图11是示出可以应用本公开内容的技术的eNB或gNB的示意性配置的第一示例的框图。注意,以下的描述以eNB作为示例,但是同样可以应用于gNB。eNB 800包括一个或多个天线810以及基站设备820。基站设备820和每个天线810可以经由RF线缆彼此连接。
天线810中的每一个均包括单个或多个天线元件(诸如包括在多输 入多输出(MIMO)天线中的多个天线元件),并且用于基站设备820发送和接收无线信号。如图11所示,eNB 800可以包括多个天线810。例如,多个天线810可以与eNB 800使用的多个频带兼容。虽然图11示出其中eNB 800包括多个天线810的示例,但是eNB 800也可以包括单个天线810。
基站设备820包括控制器821、存储器822、网络接口823以及无线通信接口825。
控制器821可以为例如CPU或DSP,并且操作基站设备820的较高层的各种功能。例如,控制器821根据由无线通信接口825处理的信号中的数据来生成数据分组,并经由网络接口823来传递所生成的分组。控制器821可以对来自多个基带处理器的数据进行捆绑以生成捆绑分组,并传递所生成的捆绑分组。控制器821可以具有执行如下控制的逻辑功能:该控制诸如为无线资源控制、无线承载控制、移动性管理、接纳控制和调度。该控制可以结合附近的eNB或核心网节点来执行。存储器822包括RAM和ROM,并且存储由控制器821执行的程序和各种类型的控制数据(诸如终端列表、传输功率数据以及调度数据)。
网络接口823为用于将基站设备820连接至核心网824的通信接口。控制器821可以经由网络接口823而与核心网节点或另外的eNB进行通信。在此情况下,eNB 800与核心网节点或其他eNB可以通过逻辑接口(诸如S1接口和X2接口)而彼此连接。网络接口823还可以为有线通信接口或用于无线回程线路的无线通信接口。如果网络接口823为无线通信接口,则与由无线通信接口825使用的频带相比,网络接口823可以使用较高频带用于无线通信。
无线通信接口825支持任何蜂窝通信方案(诸如长期演进(LTE)和LTE-先进),并且经由天线810来提供到位于eNB 800的小区中的终端的无线连接。无线通信接口825通常可以包括例如基带(BB)处理器826和RF电路827。BB处理器826可以执行例如编码/解码、调制/解调以及复用/解复用,并且执行层(例如L1、介质访问控制(MAC)、无线链路控制(RLC)和分组数据汇聚协议(PDCP))的各种类型的信号处理。代替控制器821,BB处理器826可以具有上述逻辑功能的一部分或全部。BB处理器826可以为存储通信控制程序的存储器,或者为包括被配置为执行程序的处理器和相关电路的模块。更新程序可以使BB处理 器826的功能改变。该模块可以为插入到基站设备820的槽中的卡或刀片。可替代地,该模块也可以为安装在卡或刀片上的芯片。同时,RF电路827可以包括例如混频器、滤波器和放大器,并且经由天线810来传送和接收无线信号。
如图11所示,无线通信接口825可以包括多个BB处理器826。例如,多个BB处理器826可以与eNB 800使用的多个频带兼容。如图11所示,无线通信接口825可以包括多个RF电路827。例如,多个RF电路827可以与多个天线元件兼容。虽然图11示出其中无线通信接口825包括多个BB处理器826和多个RF电路827的示例,但是无线通信接口825也可以包括单个BB处理器826或单个RF电路827。
在图11所示的eNB 800中,电子设备200的发送单元201、获取单元202、收发器可以由无线通信接口825实现。功能的至少一部分也可以由控制器821实现。例如,控制器821可以通过执行发送单元201和获取单元202的功能来对UE的BFR机制进行针对多TRP场景的配置以及获取UE的波束失败事件的上报。
(第二应用示例)
