Rel-15 NR(新无线版本15)包括一些MIMO(多进多出)特性，促进基站侧6GHz以下和6GHz以上频带的大量天线单元的使用。Rel-16 NR(新无线版本16)通过以下机制对Rel-15 NR进行了增强，这些机制包括：
引入增强的基于DFT(离散傅里叶变换)压缩的类型2码本(Type II codebook)；
支持多TRP(发送接收点，Transmission Reception Point)传输，尤其对于eMBB(增强移动宽带)和PDSCH(物理下行共享信道)；
多波束操作的增强，包括时延和/或多种重配置开销的减小，例如QCL(准共址)相关的测量重配置开销减小；
SCell(辅小区)波束失败恢复(beam failure recovery，BFR)；
L1-SINR(层1信号与干扰加噪声比)；
低PAPR(峰值平均功率比，Peak to Average Power Ratio)参考信号；
确保上行权功率传输的特性。
目前，NR(新无线)处在商业化过程中，从实际部署场景中可以确定需要进一步增强的各个方面，这样的方面包括：
Rel-16(版本16)设法减小了开销和/或时延，FR2(频率范围2)上的高速车载场景(如在高速路上高速行驶的UE)要求更积极地减少时延和开销，不仅对于小区内，还包括小区间L1/L2(层1/层2)移动性。此外，还包括减少波束失败事件的发生；
Rel-16研究了确保panel(面板)特定的UL(上行链路，简称为上行)波束选择的增强，但没有足够时间完成该工作。这为增加上行覆盖提供了一些可能，包括缓解由于满足MPE(maximum permissible exposure，最大允许暴露)规则造成的UL覆盖损失；
PDSCH之外的信道可以受益于多TRP传输(以及多panel接收)，这也包括小区间多TRP的操作。这包括一些新的多TRP的用例，如一个宏小区内的UL密集部署和/或异构网络类型的部署场景；
由于多场景SRS(探测参考信号)的使用，可以且应该进一步增强SRS，至少为了 容量和覆盖；
尽管Rel-16支持增强的Type II CSI(类型2信道状态信息)，可以感觉到一些进一步增强的空间。这包括为NC-JT用例的多TRP/panel设计的CSI(信道状态信息)和信道统计上的部分互异性的利用，如角度和时延，主要目标是FR1 FDD(频率范围1频分双工)部署。
此外，Rel-17(版本17)支持多TRP部署的增强，目标是FR1和FR2，包括：
使用多TRP和/或多panel，以Rel-16可靠性作为baseline(基础)，确定并定义改善PDSCH之外的信道(即物理下行控制信道PDCCH，物理上行共享信道PUSCH和物理上行控制信道PUCCH)的可靠性和健壮性的特性；
确定并定义QCL/TCI(传输配置指示，Transmission Configuration Indication)相关的增强，以确保小区间多TRP操作，假设基于多DCI(下行链路控制信息，简称为下行控制信息)、基于Rel-15/16 TCI架构的多PDSCH接收；
对于有多panel接收的多TRP同时传输，进行评估并定义，如果需要，对波束管理相关的内容进行增强；
对以下内容进行增强以支持HST-SFN(高速传输单频网络)部署场景：确定并定义DMRS(解调参考信号)的QCL假设的解决方案，如相同DMRS port(s)的多个QCL假设，目标是DL-only传输；如果证实其优于Rel-16 HST(版本16高速传输)增强baseline的好处，评估并通过重用统一的TCI架构定义DL和UL信号间的QCL/QCL-like关系(包括适用类型和相关需求)。
从以上可以看出，为了改善信道的可靠性和健壮性，对于部署了多TRP的场景，Rel-17支持TRP特定的波束失败检测和恢复。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现，当前对于TRP特定的波束失败检测的参考信号，使用L3(层3)信令即RRC(无线资源控制)消息进行配置。但是，当网络使用L2信令，例如MAC CE(媒体接入控制控制单元)，或L1信令，例如DCI，激活新的TCI状态后，为了更新TRP特定的波束失败检测的参考信号，网络需要发送新的RRC消息，这造成波束失败 检测的延迟，可能导致错误地触发波束失败恢复过程。
例如，在时刻t0，网络使用L2信令或L1信令激活新的TCI状态，但终端仍监听原本用于波束失败检测的参考信号直到t1时收到新的信号配置，期间可能达到配置的波束失败实例的最大值，从而触发波束失败恢复过程。如果是特殊小区，有可能触发随机接入过程，这会发生业务中断。
针对上述问题，本申请实施例提供一种波束失败检测参考信号的配置方法和装置，以支持使用RRC信令和MAC CE配置/更新用于波束失败检测的参考信号。
根据本申请实施例的一方面，通过一种波束失败检测参考信号的配置装置，所述装置包括：
第一配置单元，其使用RRC信令配置用于波束失败检测的第一参考信号；
第二配置单元，其使用MAC CE信令配置或更新所述第一参考信号。
根据本申请实施例的另一方面，提供一种波束失败检测参考信号的配置装置，所述装置包括：
第一配置单元，其使用RRC信令配置用于TRP特定的波束失败检测的参考信号；
第二配置单元，其使用所述RRC信令配置用于失败检测的参考信号。
本申请实施例的有益效果之一在于：根据本申请实施例，能够支持使用RRC信令和MAC CE配置/更新用于波束失败检测的参考信号。相较于现有机制，在PDCCH接收的TCI状态改变后，一方面，本申请能更快地使用相应的参考信号进行波束失败检测，从而避免错误地触发波束失败恢复过程以及由此造成的业务中断；另一方面，本申请能更灵活地配置/更新用于波束失败检测的参考信号，从而减少信令开销，节约空口资源。

Figure PCTCN2022085661-appb-000005
此外，针对波束失败检测过程，在NR里，支持多个波束以及波束管理。其中，MAC(媒体接入控制)实体可以被RRC配置每服务小区的波束失败恢复过程，这个过程用于当在服务SSB(s)/CSI-RS(s)上检测到波束失败时，向服务gNB指示一个新的SSB(同步信号块)或CSI-RS(信道状态信息参考信号)。通过计算低层到MAC实体的波束失败实例(instance)指示的数量，检测波束失败。
图1a～图1c是服务小区波束失败的检测或波束失败恢复的触发的示意图。
如图1a所示，波束失败检测(Beam Failure Detection,BFD)过程使用UE变量BFI_COUNTER，这个变量是波束失败实例指示的计数器，初始设置为0，每个服务小区有一个。对于每个配置了波束失败检测的服务小区，MAC实体将会：
如果从低层收到了波束失败实例指示：
启动或重启beamFailureDetectionTimer；
BFI_COUNTER加1；
如果BFI_COUNTER大于或等于beamFailureInstanceMaxCount：
如果服务小区是辅小区(SCell)，触发这个服务小区的一个BFR；
否则，在这个特殊小区(SpCell)上发起随机接入过程。
如图1b和图1c所示，MAC实体还会：
如果beamFailureDetectionTimer超时；或
如果高层重配了这个服务小区的beamFailureDetectionTimer，beamFailureInstanceMaxCount或用于波束失败检测的任何参考信号：
设置BFI_COUNTER为0。
这个过程适用于Rel-15和Rel-16的特殊小区和辅小区。
发明人发现，在Rel-15和Rel-16中，支持小区级的波束失败检测；在R17多TRP操作下，支持per-TRP的单独的BFD-RS(波束失败检测参考信号)组的波束失败检测，并且支持在不同CC(分量载波)上的小区特定的BFR和TRP特定的BFR的同时配置，但是不支持一个CC上TRP特定的BFR与Rel-15/16 BFR(即BeamFailureRecoveryConfig/BeamFailureRecoverySCellConfig-r16)的同时配置。
此外，针对TRP特定的波束失败恢复的触发，RRC配置了一些参数，例如：
-配置了2个BFD-RS组的服务小区的每BFD-RS组的波束失败检测的beamFailureInstanceMaxCount；
-配置了2个BFD-RS组的服务小区的每BFD-RS组的波束失败检测的beamFailureDetectionTimer。
以下UE变量用于波束失败检测过程：
-BFI_COUNTER(配置了2个BFD-RS组的服务小区的每BFD-RS组)：波束失败实施例指示的计数器，其初始设置为0。
对于每个配置了波束失败检测的服务小区，MAC实体将会：
1>如果这个服务小区被配置了两个BFD-RS组，对于这个服务小区的每个BFD-RS组，MAC实体将会：
2>如果从低层收到了一个BFD-RS组的波束失败实例指示：
3>启动或重启beamFailureDetectionTimer；
3>这个BFD-RS组的BFI_COUNTER加1；
3>如果BFI_COUNTER大于或等于beamFailureInstanceMaxCount：
4>触发这个服务小区的这个BFD-RS组的BFR；
2>如果这个特殊小区的两个BFD-RS组都触发了BFR且尚未成功完成：
3>在这个特殊小区上发起随机接入过程；
2>如果这个服务小区是特殊小区且为这个特殊小区的两个BFD-RS组的波束失 败恢复发起的随机接入过程成功完成：
3>设置特殊小区的每个BFD-RS组的BFI_COUNTER为0；
3>认为这个波束失败恢复过程成功完成。
2>如果这个BFD-RS组的beamFailureDetectionTimer超时；或
2>如果高层重配了这个服务小区这个BFD-RS组的beamFailureDetectionTimer，beamFailureInstanceMaxCount或用于波束失败检测的任何参考信号：
3>设置这个BFD-RS组的BFI_COUNTER为0。
2>如果收到一个C-RNTI寻址的PDCCH，指示用于传输包括这个服务小区的这个BFD-RS组的波束失败恢复信息的Enhanced BFR MAC CE或Truncated Enhanced BFR MAC CE的HARQ进程的一个新传的上行授权：
3>设置这个BFD-RS组的BFI_COUNTER为0；
3>认为这个波束失败恢复过程成功完成并取消这个服务小区这个BFD-RS组所有触发的BFRs。
2>如果这个服务小区是辅小区，且这个辅小区被去激活：
3>设置辅小区的每个BFD-RS组的BFI_COUNTER为0；
3>认为这个波束失败恢复过程成功完成并取消这个服务小区所有BFD-RS组所有触发的BFRs。
此外，针对TRP特定的波束失败检测的参考信号的配置，为了支持多TRP的波束失败检测，暂定在当前标准中引入了如下关于TRP特定的波束失败检测的参考信号的配置。

以下通过示例对本申请实施例的场景进行说明，但本申请不限于此。
图2是多TRP操作的场景的一示意图，如图2所示，TRP是gNB的一部分，其用于从终端UE接收信号或者向终端UE发送信号。在多TRP(mTRP)操作里，一个服务小区可以从两个TRPs调度UE，提供更好的PDSCH覆盖、可靠性和/或数据速率。对于多TRP，有两种不同的操作模式，即单DCI和多DCI。对于这两种模式，在RRC层提供的配置内，上行和下行操作的控制由物理层和MAC进行。在单DCI模式下，UE由两个TRPs通过相同DCI调度；在多DCI模式下，UE由每个TRP的单独的DCI调度。
图3是每个TRP的波束失败检测(BFD)/波束失败恢复(BFR)的一示意图，如图3所示，gNB通过TRP-1和TRP-2为终端(UE)提供服务。UE进行每TRP的波束失败检测。其中，TRP-1与UE之间的链路1(link-1)正常工作，即UE未检测到TRP1上的波束失败，或不触发TRP1上的波束失败恢复；但是TRP-2与UE之间的链路2(link-2)受到阻塞，即UE检测到了TRP-2上的波束失败，或触发TRP-2上的波束失败恢复。这两个TRP可能属于相同小区，也可能属于不同小区。
下面结合附图和具体实施方式对本申请实施例进行说明。
第一方面的实施例
本申请实施例提供一种波束失败检测参考信号的配置方法，该方法适用于网络设备，也适用于终端设备。
图4是本申请实施例的波束失败检测参考信号的配置方法的一示意图，如图4所示，该方法包括：
401，使用RRC信令配置用于波束失败检测的参考信号(称为第一参考信号)；
402，使用MAC CE信令配置或更新所述第一参考信号。
值得注意的是，以上附图4仅示意性地对本申请实施例进行了说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图4的记载。
在上述实施例中，通过使用RRC信令配置用于波束失败检测的参考信号，并通过使用MAC CE信令对该参考信号进行配置或更新，实现了通过RRC信令和MAC CE配置/更新用于波束失败检测的参考信号，避免了业务中断，提高了网络性能。
在一些实施例中，上述第一参考信号包括用于TRP特定的波束失败检测的参考信号(称为第二参考信号)。也即，可以使用RRC信令配置用于TRP特定的波束失败检测的参考信号。
在一些实施例中，第二参考信号包含在2个波束失败检测参考信号组中，该2个波束失败检测参考信号组有各自的组ID(标识)。
在上述实施例中，使用RRC信令配置用于波束失败检测的参考信号(第一参考信号)，可以包括以下配置的至少之一：
该RRC信令包括第一波束失败检测的参考信号组和第二波束失败检测的参考信号组，也即，通过RRC信令显式配置了两个波束失败检测的参考信号组，当第一波束失败检测的参考信号组存在时，第二波束失败检测的参考信号组强制存在；
上述第一波束失败检测的参考信号组和上述第二波束失败检测参考信号组分别包括组ID，该组ID强制存在，该组ID的值为1或者2；
上述第一波束失败检测的参考信号组和上述第二波束失败检测参考信号组分别包括一组第二参考信号，该第二参考信号包括第二参考信号ID和检测资源；其中，该第二参考信号可以是增加和/或修改的第二参考信号，该第二参考信号ID可以是从0到n-1的整数，n是每组第二参考信号最大的失败检测资源数，例如64；该检测资源例如是 SSB索引或者NZP CSI-RS资源ID等；
上述第一波束失败检测的参考信号组和上述第二波束失败检测参考信号组分别包括一组释放的第二参考信号ID。
在另一些实施例中，第二参考信号包含在1个波束失败检测参考信号组中，该1个波束失败检测参考信号组有组ID。
在上述实施例中，使用RRC信令配置用于波束失败检测的参考信号(第一参考信号)，可以包括以下配置的至少之一：
该RRC信令包括第三波束失败检测参考信号组，也即，通过RRC信令显式配置了1个波束失败检测的参考信号组，该第三波束失败检测参考信号组包括组ID，该组ID强制存在，该组ID的值为1或2；
上述第三波束失败检测参考信号组包括一组第二参考信号，该第二参考信号包括第二参考信号ID和检测资源；其中，该第二参考信号可以是增加和/或修改的第二参考信号，该第二参考信号ID可以是从0到n-1的整数，n是每组第二参考信号最大的失败检测资源数，例如64；该检测资源例如是SSB索引或者NZP CSI-RS资源ID等；
上述第三波束失败检测参考信号组包括一组释放的第二参考信号ID。
在上述实施例中，上述第三波束失败检测参考信号组的组ID可以与coresetpool(称为第一coresetpool)相关，或者说，上述第三波束失败检测参考信号组对应第一coresetpool。对于多TRP操作的多DCI模式，即不同TRP通过不同DCI调度。不同的DCI关联不同coresetpool中的coreset(控制资源集合)。例如，TRP-1的DCI关联coresetpool 1中的coreset，TRP-2的DCI关联coresetpool 2中的coreset。即关联的coresetpool可用于识别TRP。
在上述实施例中，不同于第三波束失败检测参考信号组的另一个波束失败检测参考信号组中的第二参考信号，可以由低层通过PDCCH接收的TCI状态确定。该另一个波束失败检测参考信号组也对应一个coresetpool(控制资源集合池)。
在又一些实施例中，第二参考信号包含在1个波束失败检测参考信号组中，该1个波束失败检测参考信号组没有组ID。
在上述实施例中，使用RRC信令配置用于波束失败检测的参考信号(第一参考信号)，可以包括以下配置的至少之一：
该RRC信令包括第四波束失败检测参考信号组，该第四波束失败检测参考信号组没有组ID；
上述第四波束失败检测参考信号组包括一组第二参考信号，该第二参考信号包括第二参考信号ID、第二参考信号关联的coresetpool信息以及检测资源；其中，该第二参考信号ID可以是从0到2n-1的整数，n是每组第二参考信号最大的失败检测资源数，例如64；该检测资源例如是SSB索引或者NZP CSI-RS资源ID等；
上述第四波束失败检测参考信号组包括一组释放的第二参考信号ID。
在上述实施例中，关联的coresetpool的信息例如是coresetpool索引，基于这个域，终端设备能够确定第二参考信号所在的波束失败检测参考信号组，例如，coresetpool索引为1表示该第二参考信号属于第二波束失败检测参考信号组；未关联或者关联的coresetpool索引为0表示该第二参考信号属于第一波束失败检测参考信号组。
以上各个实施例仅对使用RRC信令配置用于波束失败检测的第一参考信号进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
在本申请实施例中，还可以使用RRC信令配置用于失败检测的参考信号(称为第三参考信号)。
在上述实施例中，该RRC信令可以包括一个指示域(称为第一指示域)，该第一指示域用于指示上述用于失败检测的参考信号(第三参考信号)的目的(purpose)，以指示终端设备监听相关参考信号的目的是小区检测还是波束失败检测。
在上述实施例中，如果该RRC信令配置了前述用于TRP特定的波束失败检测的参考信号(第二参考信号)，则上述第一指示域的值被配置为rlf(无线链路失败)，例如上述第一指示域的值总是被配置为rlf，或者，上述第一指示域的值仅被配置为rlf。
在本申请实施例中，还可以使用RRC信令为上述第一参考信号或者上述第二参考信号配置或指示或关联一个PDCCH接收的TCI状态的信息。
在上述实施例中，该PDCCH接收的TCI状态可以通过RRC信令配置。
在上述实施例中，该TCI状态的信息可以是TCI状态ID，可选的，该TCI状态的信息还可以包括小区信息和/或BWP(部分带宽)信息，小区信息例如为服务小区的索引或者PCI(物理小区标识)索引，BWP信息例如为BWP ID。
在前述实施例中，以第一参考信号包括用于TRP特定的波束失败检测的参考信号(第二参考信号)为例进行了说明，在一些实施例中，第一参考信号也可以不包括前述用于TRP特定的波束失败检测的参考信号(第二参考信号)，低层可以通过PDCCH接 收的TCI状态确定用于TRP特定的波束失败检测的参考信号(第二参考信号)，并且确定该第二参考信号所关联的coresetpool，例如确定该第二参考信号关联了1个coresetpool或者2个coresetpool。
在本申请实施例中，RRC信令包括RRC消息、RRC消息里的信息单元(IE)、RRC消息里的域(field)等，下面通过具体的示例对本申请实施例的上述RRC信令的实施方式进行说明。
在前述实施例中，RRC信令支持以下三种可能性中的至少之一：
可能性1：BFD-RS(波束失败检测参考信号)包括在2个BFD-RS组里，每个组有各自的组ID；
可能性2：BFD-RS包括在1个BFD-RS组里，这组有组ID；
可能性3：BFD-RS包括在1个BFD-RS组里，这组没有组ID。
在一些实施例中，RRC信令支持以上三种可能性，即RRC消息可以包括1个或2个BFD-RS组，每个组可以有或者没有各自的组ID。在标准中，关于无线链路监测配置以及无线链路监测参考信号的内容，描述上可以有如下补充或改进，其中，加下划线的内容是本实施例区别于现有标准不同的地方，例如，不包括加粗加下划线的部分；又例如，包括加粗加下划线的内容，作为额外增强的部分。

根据上述实施例中，RRC信令能支持BFD-RS组的显式配置，例如可以包括1或2个BFD-RS组，每个组有各自的组ID等。此外，还能支持BFD-RS组的delta配置。由此，兼具RRC信令设计灵活性，具有前向兼容性，同时可以部分简化终端的设计，降低了成本。
在本申请实施例中，使用RRC信令配置了上述用于波束失败检测的参考信号(第一参考信号)之后，还可以使用MAC CE信令配置或更新该第一参考信号。
在上述实施例中，MAC CE信令可以是网络设备用于指示TCI状态的MAC CE，该TCI状态为一个服务小区或一组服务小区的一个coreset(控制资源集合)的PDCCH接收的TCI状态，或者，该MAC CE信令为用于配置或更新上述用于波束失败检测的第 一参考信号的MAC CE(称为第一MAC CE)。相比于前述网络设备用于指示TCI状态的MAC CE，该第一MAC CE为新的MAC CE。
在上述实施例中，第一MAC CE可以包括以下信息中的至少一个：
波束失败检测参考信号组的信息；例如波束失败检测参考信号组的ID(1比特)；
一个波束失败检测参考信号组的用于波束失败检测的参考信号的信息；例如波束失败检测的参考信号索引(6比特)；
服务小区的信息；
服务小区列表信息。
可选的，第一MAC CE还可以包括前述用于波束失败检测的第一参考信号的一个或多个QCL假设，例如SSB索引或NZP CSI-RS资源ID等。
在上述实施例中，服务小区的信息例如包括服务小区的索引或服务小区的位图(bitmap)。这里的服务小区可以是：为终端设备配置的服务小区、和/或配置了两个波束失败检测参考信号组的服务小区、和/或在相同的公共更新小区列表里的服务小区等。
在上述实施中，服务小区列表信息例如为：公共更新小区列表的信息、或共享TCI状态的小区列表的信息等。公共更新小区列表是可以使用一个MAC CE同时更新TCI关系(relation)的服务小区的列表，例如simultaneousTCI-UpdateList1-r16，simultaneousTCI-UpdateList1-r16，simultaneousU-TCI-UpdateList1-r17，simultaneousU-TCI-UpdateList2-r17，simultaneousU-TCI-UpdateList3-r17，simultaneousU-TCI-UpdateList4-r17。公共更新小区列表的信息可以是指示这些列表的名字的信息，例如list 1的信息为1，list 2的信息为2，或者指示列表出现顺序的信息，例如第一个出现的列表的信息为1，第二个出现的列表的信息为2等。共享TCI状态的小区列表是指使用相同的TCI状态(state)配置的服务小区的列表。
在上述实施例中，第一MAC CE的长度是可变的，其MAC子头可以包括用于指示该第一MAC CE的长度的L域和用于指示该L域的F域。
在上述实施例中，该第一MAC CE的MAC子头可以包括LCID和eLCID。其中，LCID为34，即扩展的逻辑信道ID域(1字节eLCID域)；eLCID使用UL-SCH的1字节eLCID的保留LCID值里的一个，例如239、238或其他。
在前述实施例中，如果使用RRC信令配置用于波束失败检测的参考信号(第一参考信号)时，为用于波束失败检测的参考信号(第一参考信号)关联了一个PDCCH接收的TCI状态信息；或者，如果RRC信令为每个PDCCH接收的TCI状态关联了一个 用于波束失败检测的参考信号(第一参考信号)，则前述MAC CE信令可以是网络设备用于指示TCI状态的MAC CE。另一方面，如果使用RRC信令配置用于波束失败检测的参考信号(第一参考信号)时，用于波束失败检测的参考信号(第一参考信号)未关联一个PDCCH接收的TCI状态信息；或者，如果PDCCH接收的TCI状态未关联一个用于波束失败检测的参考信号(第一参考信号)，则前述MAC CE信令可以是前述第一MAC CE。
下面通过具体的示例对本申请实施例的MAC CE信令的实施方式进行说明。
在一些实施例中，前述第一MAC CE的格式有以下两种：
格式1：不包括BFD-RS的QCL假设；
格式2：包括BFD-RS的QCL假设。
图5是第一MAC CE的格式1的一个示例的示意图，示出了包含1字节Ci域的情况；图6是第一MAC CE的格式1的另一个示例的示意图，示出了包含4字节Ci域的情况。
如图5和图6所述，第一MAC CE的格式1至少包括以下域：
Ci域：指示是否包括服务小区索引为i的服务小区的BFD-RS信息；Ci＝0，表示不包括服务小区索引为i的服务小区的BFD-RS信息；
Set id域：指示这个字节里包括的BFD-RS信息所属的BFD-RS组或相应的coresetpool；
P域：指示接下来的字节是不是与本字节的BFD-RS信息相同服务小区相同set的BFD-RS信息，例如P＝0指示接下来的字节不是与本字节的BFD-RS信息相同服务小区相同set的BFD-RS信息(这种情况下，下一个字节使用包括set id+P域的字节)，P＝1表示接下来的字节是与本字节的BFD-RS信息相同服务小区相同set的BFD-RS信息(这种情况下，下一个字节使用R+R的字节)；
RS ID域：指示BFD-RS index，6比特；
R域：保留(Reserved)域。
在上述实施例中，可选的，第一MAC CE的格式1还可以包括以下域(图5和图6中未示出)：
Ni域：指示包括服务小区索引为i的服务小区/第i个Ci域中值为1的服务小区的BFD-RS组的个数。
图7是第一MAC CE的格式2的一个示例的示意图，示出了包含1字节Ci域的情 况；图8是第一MAC CE的格式2的另一个示例的示意图，示出了包含4字节Ci域的情况。
如图7和图8所示，相较于第一MAC CE的格式1，第一MAC CE的格式2至少还包括以下域：
QCL assumption(QCL假设)域：指示上一个字节里包括的BFD-RS的QCL假设；
T域：指示接下来的字节是不是与本字节的QCL assumption对应的BFD-RS的另一个QCL assumption信息，例如T＝0指示接下来的字节不是与本字节的QCL assumption对应的BFD-RS的另一个QCL assumption信息(这种情况下，下一个字节使用包括另外的BFD-RS信息)，T＝1表示接下来的字节是与本字节的QCL assumption对应的BFD-RS的另一个QCL assumption信息(这种情况下，下一个字节使用R+R的字节)。
在上述实施例中，可选的，第一MAC CE的格式2还可以包括以下域(图7和图8中未示出)：
Ni域：指示包括服务小区索引为i的服务小区/第i个Ci域中值为1的服务小区的BFD-RS组的个数。
以上各个实施例仅对使用MAC信令配置或更新用于波束失败检测的第一参考信号进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
前述各实施例的方法可以由网络设备实施，例如网络设备通过发送上述RRC信令和上述MAC CE信令进行上述配置，也可以由终端设备实施，例如终端设备通过接收上述RRC信令和所述MAC CE信令完成上述配置。
在本申请实施例中，可选的，终端设备的MAC实体还可以在前述MAC CE信令关联了服务小区的波束失败检测参考信号组的情况下，将该服务小区的波束失败检测参考信号组的波束失败实例的计数器(BFI_COUNTER)设置为0。
例如，如果终端设备收到一个MAC CE信令，该MAC CE信令可更新或重配一个服务小区的一个波束失败检测参考信号组中用于波束失败检测的任意参考信号，则上述MAC实体将该波束失败检测参考信号组的波束失败实例的计数器设置为0。
再例如，如果高层重配了一个服务小区的一个波束失败检测参考信号组的beamFailureDetectionTimer、beamFailureInstanceMaxCount、或用于波束失败检测的任何参考信号，或者，如果MAC CE信令更新或重配了上述服务小区的上述波束失败检测 参考信号组的用于波束失败检测的任何参考信号，则上述MAC实体将该波束失败检测参考信号组的波束失败实例的计数器设置为0。
再例如，如果高层重配了一个服务小区的一个波束失败检测参考信号组的beamFailureDetectionTimer或beamFailureInstanceMaxCount，或者，上述服务小区的上述波束失败检测参考信号组的任何参考信号被重配或更新，则上述MAC实体将该波束失败检测参考信号组的波束失败实例的计数器设置为0。
在上述实施例中，服务小区被配置了两个波束失败检测参考信号组(称为第一波束失败检测参考信号组和第二波束失败检测参考信号组)。
例如，RRC信令为该服务小区配置了用于TRP特定的波束失败检测的参考信号，该参考信号包含在2个波束失败检测参考信号组中，每个波束失败检测参考信号组有各自的组ID。
再例如，RRC信令为该服务小区配置了用于TRP特定的波束失败检测的参考信号，该参考信号包含在1个波束失败检测参考信号组中，该波束失败检测参考信号组有组ID，低层通过PDCCH接收的TCI状态确定另一个波束失败检测参考信号组的波束失败检测参信号。
再例如，RRC信令为该服务小区配置了用于TRP特定的波束失败检测的参考信号，该参考信号包含在1个波束失败检测参考信号组中，该波束失败检测参考信号组没有组ID，终端设备确定该参考信号关联了2个coresetpool。
再例如，RRC信令没有为该服务小区配置用于TRP特定的波束失败检测的参考信号，低层通过PDCCH接收的TCI状态确定用于TRP特定的波束失败检测的参考信号，并且确定该参考信号关联了2个coresetpool。
在上述实施例中，第一波束失败检测参考信号组例如为以下情况之一：
情况1：BFD-RS组ID为1的BFD-RS组；
情况2：BFD-RS组ID为1的BFD-RS组，如果配置了；或低层通过PDCCH接收TCI状态确定的另外一个BFD-RS组(如果配置了BFD-RS组ID为2的BFD-RS组)；
情况3：所有未关联coresetpool或关联了索引为0的coresetpool的参考信号组成的BFD-RS组；
情况4：低层通过PDCCH接收TCI状态确定的未关联coresetpool或关联了索引为0的coresetpool的参考信号组成的BFD-RS组。
在上述实施例中，第二波束失败检测参考信号组例如为以下情况之一：
情况1：BFD-RS组ID为2的BFD-RS组；
情况2：BFD-RS组ID为2的BFD-RS组，如果配置了；或低层通过PDCCH接收TCI状态确定的另外一个BFD-RS组(如果配置了BFD-RS组ID为1的BFD-RS组)；
情况3：(所有)关联了索引为1的coresetpool的参考信号组成的BFD-RS组；
情况4：低层通过PDCCH接收TCI状态确定的(所有)关联了索引为1的coresetpool的参考信号组成的BFD-RS组。
以上各个实施例仅对服务小区配置的两个波束失败检测参考信号组进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
图9是本申请实施例的波束失败检测参考信号的配置方法的另一示意图，如图9所示，该方法包括：
901：使用RRC信令配置用于TRP特定的波束失败检测的参考信号；以及
902：使用所述RRC信令配置用于失败检测的参考信号。
值得注意的是，以上附图9仅示意性地对本申请实施例进行了说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图9的记载。
在上述实施例中，使用RRC信令配置用于TRP特定的波束失败检测的参考信号，并使用RRC信令配置用于失败检测的参考信号，相较于现有技术，能只为未配置小区特定的波束失败检测参考信号的小区配置TRP特定的波束失败检测参考信号，一方面，避免了错误配置和不必要的失败检测或失败恢复的触发，以及从而造成的业务中断；另一方面，减少了信令开销，从而节约了空口资源。
在上述实施例中，该RRC信令可以包括一个指示域(称为第一指示域)，该第一指示域用于指示上述用于失败检测的参考信号(第三参考信号)的目的(purpose)，以指示终端设备监听相关参考信号的目的是小区检测还是波束失败检测。
在上述实施例中，由于该RRC信令配置了前述用于TRP特定的波束失败检测的参考信号，因此上述第一指示域的值被配置为rlf(无线链路失败)，例如上述第一指示域的值总是被配置为rlf，或者，上述第一指示域的值仅被配置为rlf。
关于该RRC信令的相关内容，已经在前面做了说明，此处不再赘述。
根据本申请实施例的方法，避免了业务中断，提高了网络性能。
