Description

小区间的波束管理方法及装置 技术领域
本申请涉及通信领域。
背景技术
Rel-15 NR中包括了一些MIMO(多入多出，multiple input multiple output)特性，以促进基站侧6GHz以下和6GHz以上频带的大量天线单元的使用。
Rel-16 NR中通过以下措施增强了Rel-15 NR：引入增强的基于离散傅里叶变换(Discrete Fourier Transform，DFT)压缩的Type II码书(codebook)；支持多发送接收点(Transmission Reception Point，TRP)传输，尤其对于增强移动宽带(Enhanced Mobile Broadband，eMBB)和物理下行共享信道(Physical Downlink Shared Channel，PDSCH)；多波束操作的增强，包括时延和/或多种准共址(Quasi Co-Location，QCL)相关的测量重配置开销的减小；辅小区(SCell)波束失败恢复(beam failure recovery，BFR)；L1-SINR；低峰均值比(Peak to Average Power Ratio，PAPR)参考信号；确保上行全功率传输的特性。
NR正处在商业化进程中，从实际部署场景中，可以确定需要进一步增强的各个方面，例如，关于小区间波束管理(Inter-cell beam management，ICBM)，包括：
Rel-16设法减小了开销和/或时延，FR2上的高速车载场景(例如在高速路上高速行驶的终端设备)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层以及L2层的移动性，这还包括减少波束失败事件的发生；
Rel-16研究了确保面板(panel)特定的上行(UL)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，包括缓解由于满足最大允许暴露(maximum permissible exposure，MPE)规则造成的上行覆盖损失；
PDSCH之外的信道可以受益于多TRP传输(以及多面板接收)，这也包括小区间多TRP的操作。这包括一些新的多TRP的用例，例如一个宏小区内的上行密集部署和/或异构网络类型的部署场景；
由于多场景SRS的使用，至少为了容量和覆盖,可以且应该进一步增强信道探测参考信号(Sounding Reference Signal，SRS)；
尽管Rel-16支持增强的Type II的信道状态信息(Channel State Information，CSI)，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/面板设计的CSI和信道统计上的部分互异性的利用，例如角度和时延，其主要目标是FR1频分双工(Frequency Division Duplex，FDD)部署。
因此，Rel-17NR定义NR MIMO的进一步的增强，包括多波束操作的增强，主要目标是FR2，也适用于FR1，具体包括：
1)对于小区内和小区间场景，确定并定义促进更高效(更低时延和开销)的下行/上行(DL/UL)波束管理的特性，以支持更高的终端设备速度和/或更多的配置的传输配置指示(transmission configuration indication，TCI)状态，具体如下：
下行和上行、数据和控制传输/接收的公共波束，尤其对于带内载波聚合(intra-band CA)；
下行和上行波束指示统一的TCI架构；
以上特性信令机制的增强，以更多使用动态控制信令(相对于RRC)改善时延和效率；
对于小区间的波束管理，一个终端设备仅向单个小区发送或从单个小区接收(即当波束选择完成时服务小区不改变)。这包括L1-only测量/上报(即没有L3影响)和任意物理小区标识(PCI)的小区关联的波束指示；其中，该波束指示基于Rel-17统一的TCI架构；重用小区间(inter-cell)mTRP的波束测量/上报机制；以及仅考虑分布单元内(intra-DU)和同频情况。
2)考虑缓解由于MPE造成的上行覆盖损失，确定并定义促进装备了多面板的终端设备的上行波束选择的特性，基于上行波束指示，使用上行快速面板选择的统一的TCI架构。
应该注意，上面对技术背景的介绍只是为了方便，对本发明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发明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
连接状态的终端设备基于参考信号(例如同步信号块SSB和/或信道状态信息参考信号CSI-RS)和网络配置的信号质量阈值，执行激活BWP(带宽部分，Bandwidth  part)里的无线链路监听(Radio Link Monitoring，RLM)。其中，基于SSB的无线链路监听基于初始下行BWP关联的SSB，且仅为初始下行BWP和包括初始下行BWP关联的SSB的下行BWP(DL BWPs)配置；对于其他下行BWP，仅执行基于CSI-RS的无线链路监听。
终端设备监听主小区(PCell)的下行无线链路质量，向高层指示失步或同步状态；如果终端设备配置了辅小区组(SCG)，终端设备监听辅小区组的主辅小区(PSCell)的下行无线链路质量。
对于一个特殊小区(包括主小区和主辅小区)的每个下行BWP，为了无线链路监听，由failureDetectionResources通过一组相应的RadioLinkMonitoringRS为终端设备配置一组资源索引。
如果一个终端设备被配置了一个服务小区的多个下行BWP，那么，该终端设备使用这个激活下行BWP的RadioLinkMonitoringRS提供的资源索引相应的参考信号，执行无线链路监听；或者，如果未提供这个激活下行BWP的RadioLinkMonitoringRS，使用这个激活下行BWP上的控制资源集(CORESET)里PDCCH接收关联的激活TCI状态提供的参考信号。
如果终端设备未被提供RLM RS(RadioLinkMonitoringRS)且该终端设备被提供了包括一个或多个CSI-RS的PDCCH接收关联的TCI状态，那么：
对于无线链路监听，如果PDCCH接收关联的激活TCI状态仅包括一个参考信号(RS)，那么，该终端设备使用PDCCH接收关联的激活TCI提供的参考信号；
如果PDCCH接收关联的激活TCI状态包括两个参考信号，那么，该终端设备期望一个参考信号配置的QCL类型(qcl-Type)设为“typeD”且该终端设备为无线链路监听使用这个QCL类型设为“typeD”的参考信号；该终端设备不期望两个参考信号都被配置为QCL类型设为“typeD”。对于无线链路监听，不要求终端设备使用一个非周期或半持续参考信号。
发明人发现，基于现有技术，如果一个终端设备未被提供无线链路监听的参考信号(RLM RS)且该终端设备被提供了包括一个或多个CSI-RS的PDCCH接收关联的TCI状态，那么为了无线链路监听，该终端设备使用PDCCH接收关联的激活TCI状态提供的参考信号。
而对于小区间波束管理，存在以下问题：当为一个终端设备激活服务小区之外一 个小区的下行专用信道(例如，物理下行控制信道PDCCH和/或物理下行共享信道PDSCH)接收关联的TCI状态时，且如果该终端设备未被提供无线链路监听的参考信号，那么按照现有技术，该终端设备使用为服务小区之外的这个小区的激活TCI状态提供的参考信号进行无线链路监听，这无法用于服务小区的无线链路失败(Radio Link Failure，RLF)检测，可能延迟无线资源控制(Radio Resource Control，RRC)连接恢复，造成业务中断。
另外，基于现有技术，如果一个终端设备未被提供无线链路监听的参考信号且该终端设备被提供了包括一个或多个PDCCH接收关联的TCI状态，每个TCI状态包括一个或两个参考信号，每个参考信号关联一个服务小区。对于小区间波束管理，TCI状态需要关联服务小区之外的一个小区的下行专用信道，当前机制无法支持这种配置，无法实现小区间波束管理。

其中，基站可以包括但不限于：节点B(NodeB或NB)、演进节点B(eNodeB或eNB)以及5G基站(gNB)，等等，此外还可包括远端无线头(RRH，Remote Radio Head)、远端无线单元(RRU，Remote Radio Unit)、中继(relay)或者低功率节点(例如femto、pico等等)。并且术语“基站”可以包括它们的一些或所有功能，每个基站可以对特定的地理区域提供通信覆盖，例如5G基站gNB可以包括一个gNB CU和一个或多个gNB DU，其中CU/DU是具有gNB部分功能的gNB的一个逻辑节点。术语“小区”可以指的是基站和/或其覆盖区域，这取决于使用该术语的上下文。一个gNB-DU支持一个或多个小区，一个小区仅由一个gNB-DU支持。

以下通过示例对本申请实施例的场景进行说明，但本发明不限于此。
图1是本申请实施例的通信***的一示意图，其示意性说明了以终端设备和网络设备为例的情况，如图1所示，通信***100可以包括：网络设备101和终端设备102。为简单起见，图1仅以一个终端设备为例进行说明。网络设备101例如为NR的网络设备gNB。
在本申请实施例中，网络设备101和终端设备102之间可以进行现有的业务或者 未来可实施的业务。例如，这些业务包括但不限于：增强的移动宽带(eMBB，enhanced Mobile Broadband)、大规模机器类型通信(mMTC，massive Machine Type Communication)和高可靠低时延通信(URLLC，Ultra-Reliable and Low-Latency Communication)，等等。
例如，终端设备102使用服务小区之外的小区(非服务小区)上的波束进行通信。以下对本申请实施例的场景进行具体说明。
例如，对于小区间波束管理的场景，网络设备101通过服务小区和服务小区之外的一个小区，即非服务小区为终端设备102提供服务，该服务小区和非服务小区属于网络设备101的相同的分布单元(DU)。
图2是本申请实施例的小区间波束管理的场景的一示意图。如图2所示，网络设备101为终端设备102配置了服务小区(小区1)上的波束1和非服务小区(小区2)上的波束2，由于终端设备102的移动，网络设备101先后使用服务小区上的波束1和非服务小区上的波束2与该终端设备102通信。
又例如，对于小区间多TRP(mTRP)的场景，网络设备通过TRP-1和TRP-2为终端设备102提供服务，这两个TRP属于不同小区。
在本申请实施例中，TRP是从终端设备接收信号和/或向终端设备发送信号的网络设备的一部分。在多TRP(mTRP)操作里，一个服务小区可以从两个TRP调度终端设备，提供更好的PDSCH覆盖、可靠性和/或数据速率，这两个TRP可能属于相同小区，也可能属于不同小区。对于多TRP，有两种不同的操作模式，即单DCI(下行链路控制信息，Downlink Control Information)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层进行。在单DCI模式下，终端设备由两个TRP通过相同的DCI调度；在多DCI模式下，终端设备由每个TRP的单独的DCI调度。
图3是本申请实施例的小区间多TRP的场景的一示意图。如图3所示，网络设备101部署了两个TRP，即TRP1和TRP2。网络设备101通过TRP1和TRP2与终端设备102进行工作，TRP1和TRP2属于不同小区，例如，TRP1属于小区，TRP2属于小区2。TRP1使用小区1的波束并通过链路1与使用面板1的终端设备102进行通信，TRP2使用小区2的波束并通过链路2与使用面板2的终端设备102进行通信。
在图2和图3所示的场景中，当为终端设备102激活非服务小区(小区2)的下行专用信道接收关联的TCI状态时，如果该终端设备102未被提供无线链路监听的参考信号，那么按照现有技术，该终端设备102使用为非服务小区的激活TCI状态提供的参考信号进行无线链路监听，这无法用于服务小区(小区1)的无线链路失败检测，可能延迟RRC连接恢复，造成业务中断。
另外，基于现有技术，如果终端设备102未被提供无线链路监听的参考信号且该终端设备102被提供了包括一个或多个PDCCH接收关联的TCI状态，每个TCI状态包括一个或两个参考信号，每个参考信号关联服务小区(小区1或其他服务小区(在配置了载波聚合或双连接的情况下))。对于小区间波束管理，TCI状态需要关联非服务小区(小区2)的下行专用信道，当前机制无法支持这种配置，无法实现小区间波束管理。
下面结合附图对本申请实施例的各种实施方式进行说明。这些实施方式只是示例性的，不是对本发明的限制。
实施例1
本申请实施例提供了一种小区间的波束管理方法，该方法应用于终端设备。例如，该方法应用于图1至图3中的终端设备102。
图4是本申请实施例1的小区间的波束管理方法的一示意图。如图4所示，该方法包括：
步骤401：从网络设备接收非服务小区的波束的配置；以及
步骤402：使用该网络设备配置的用于无线链路失败检测的参考信号进行无线链路失败检测；或者，
步骤403：使用服务小区关联的TCI状态的参考信号进行无线链路失败检测。
这样，终端设备在从网络设备接收了非服务小区的波束的配置的情况下，使用网络设备配置的用于无线链路失败检测的参考信号进行无线链路失败检测，或者，使用服务小区关联的TCI状态的参考信号进行无线链路失败检测，这样，在小区间波束管理中，能够进行服务小区的无线链路失败检测，避免RRC连接恢复的延迟和业务中断，保证***性能。
在本申请实施例中，在步骤401之后，可以执行步骤402和步骤403中的一个步骤。例如，在从网络设备接收了用于无线链路失败检测的参考信号的配置的情况下， 执行步骤402，在没有从网络设备接收用于无线链路失败检测的参考信号的配置的情况下，执行步骤403。
在本申请实施例中，当终端设备配置了载波聚合时，服务小区可以包括特殊小区和/或主小区；当终端设备配置了双连接时，服务小区可以包括特殊小区、主小区组的主小区和辅小区组的主辅小区中的至少一个；当终端设备配置了载波聚合和双连接时，服务小区可以包括特殊小区、主小区组的主小区和辅小区组的主辅小区中的至少一个。
在本申请实施例中，非服务小区是指服务小区以外的一个小区。
在步骤401中，终端设备从网络设备接收非服务小区的波束的配置，也就是说，网络设备为终端设备配置了非服务小区的波束。
也就是说，终端设备从网络设备接收服务小区之外的一个小区的波束的配置，也就是说，网络设备为终端设备配置了服务小区之外的一个小区的波束。
图5是本申请实施例1的实现步骤401的方法的一示意图。如图5所示，该方法包括：
步骤501：从网络设备接收小区间波束管理的参考信号信息和/或小区间波束管理的小区信息；和/或，
步骤502：从网络设备接收非服务小区的TCI状态信息。
在本申请实施例中，可以执行步骤501和步骤502中的至少一个步骤，另外，步骤501和步骤502都被执行时，不对这两个步骤的执行顺序进行限制。
在本申请实施例中，该小区间波束管理的参考信号信息和/或该小区间波束管理的小区信息是对应于小区的信息。也就是说，该小区间波束管理的参考信号信息和/或该小区间波束管理的小区信息是小区级的信息。
在本申请实施例中，该小区间波束管理的参考信号信息的参考信号可以包括SSB和/或CSI-RS。
在该情况下，例如，该小区间波束管理的参考信号信息包括来自该非服务小区的SSB索引和/或CSI-RS标识，也就是说，该小区间波束管理的参考信号信息包括来自服务小区之外的该小区的SSB索引和/或CSI-RS标识。
在本申请实施例中，小区信息可以包括物理小区标识(Physical Cell ID，PCI)。
在该情况下，例如，该小区间波束管理的小区信息包括该非服务小区的物理小区 标识，也就是说，该小区间波束管理的小区信息包括服务小区之外的该小区的物理小区标识。
在步骤502中，终端设备从网络设备接收非服务小区的TCI状态信息，也就是说，网络设备向终端设备发送非服务小区的TCI状态信息。
也就是说，终端设备从网络设备接收服务小区之外的一个小区的TCI状态信息，也就是说，网络设备向终端设备提供服务小区之外的一个小区的TCI状态信息。
这样，在一个终端设备未被提供无线链路监听的参考信号且该终端设备被提供了包括一个或多个下行专用信道接收关联的TCI状态的情况下，能够实现小区间波束管理。
在本申请实施例中，该TCI状态信息可以是统一的TCI状态(unified TCI state)信息、PDCCH接收关联的TCI状态信息或下行TCI状态信息。
在本申请实施例中，该非服务小区的TCI状态信息例如包括，该非服务小区的TCI状态信息关联到该小区间波束管理的参考信号信息和/或该小区间波束管理的小区信息(上述小区级的信息)；或者，该非服务小区的TCI状态信息包括该小区间波束管理的参考信号信息和/或该小区间波束管理的小区信息(例如物理小区标识)；或者，该非服务小区的TCI状态信息包括一个或多个QCL类型。例如，该非服务小区的TCI状态信息包括两个QCL类型。
在本申请实施例中，该QCL类型应用QCL信息，该QCL信息包括服务小区索引域，以及非服务小区的小区信息或参考信号。
在该情况下，该终端设备应用该非服务小区的小区信息或参考信号，和/或，忽略该服务小区索引域。
例如，一个QCL类型应用QCL信息，QCL信息包括服务小区索引域，其表示配置参考信号的终端设备的一个服务小区，如果这个域缺省(absent)，则适用于配置该TCI状态的服务小区；
另外，QCL信息还可以包括非服务小区或服务小区之外的一个小区的PCI或参考信号，终端设备应用这个信息，忽略上述QCL信息包括的服务小区索引域。
例如，关于RRC对TCI状态的配置，对TCI状态IE(TCI-State information element)的修改可以是增加一个新的域。
例如，该TCI状态IE使用抽象语法标记ASN.1数据格式可以表示为：
Figure PCTCN2022070834-appb-000001
对于增加的一个新的域的描述如下：
Figure PCTCN2022070834-appb-000002
有条件的存在 解释
CSI-RS-Indicated 如果包含csi-rs，则此字段必须存在，否则不存在。
ICBM-Config 如果包含IE1/field1，则该字段是可选的，需要N；否则，它不存在。
这里，IE1或field1是为了小区间波束管理引入的非服务小区(服务小区之外的一个小区)的波束或参考信号或小区标识或TCI状态的IE或域，或其所在的IE或域。
