Description

资源更新方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种资源更新方法及装置。
背景技术
为了解决波束较窄的问题，在NR中同时引入了波束失败恢复(Beam Failure Recovery，BFR)或者链路恢复进程的机制。由于信道快速变化，会导致终端接收到的波束的质量的波动，当终端发现接收的波束质量低于一定的门限且发生频次达到预定条件的时候，就会触发终端的BFR流程。具体的，当终端发现波束失败后，终端会在高层信配置好的物理随机接入信道(Physical Random Access Channel，PRACH)资源上发送PRACH作为资源更新请求，之后会接收物理下行控制信道(Physical Downlink Shared Channel，PDCCH)作为基站对资源更新请求的响应。高层信令会配置终端接收资源更新响应的搜索空间及其关联的控制资源集合(Control Resource Set,CORESET)，在该CORESET上就不会配置其他搜索空间。终端在接收资源更新响应的PDCCH时，假设PDCCH的解调参考信号(Demodulation Reference Signal，DMRS)与一个高层配置的索引为q new的信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)或同步信号和物理广播信道块(Synchronization Signal and Physical Broadcast Channel block,SS/PBCH block)(简称SSB)是准共址(quasi co-located，QCL)。q new是由终端设备从高层配置的候选波束索引中选出来的一个索引，且通过隐式的方式终端将q new推荐至网络侧。
BFR流程分别在协议版本15(Release 15，R15)和Release16中得到了广泛的研究。其中，Release 15研究的是特殊小区(Special Cell，sPCell)的BFR，其中sPCell包含主小区(Primary Cell，PCell)和主辅小区(Primary Secondary Cell，PSCell)；Release16研究的则是辅小区(Secondary Cell，SCell)的BFR。
目前，NR Rel-16支持多发送接收点(multi-Transmission and Reception Point，multi-TRP)传输，支持终端和多个TRP同时进行通信。进一步地，协议支持基于单个下行控制信息(Downlink Control Information，DCI)触发或调度的mutli-TRP传输，也支持基于多个DCI触发或调度的multi-TRP传输。在基于多个DCI触发或调度的multi-TRP传输场景中，可以分为两类CORESET，第一CORESETs是指没有被配置CORESET Pool Index或者CORESET Pool Index被配置取值为0的CORESET，第二CORESETs是指CORESET Pool Index被配置为取值为1的CORESET。其中，第一CORESETs和第二CORESETs分别对应于不同的TRP。
但是，目前协议的链路恢复进程是对于小区而言的，并未针对multi-TRP场景的链路恢复进程(或者波束恢复进程)进行任何标准化工作。因此，支持面向TRP的链路恢复进程，实现在multi-TRP传输场景中各TRP链路的快速恢复，尤其是在终端设备接收到TRP发送的响应后对空域信息的更新是亟待解决的问题。

NR Rel-16支持基于multi-TRP的传输，也即支持终端设备和一个或多个TRP进行通信。但是，目前协议的链路恢复进程是对于小区而言的，并未针对multi-TRP场景的链路恢复进程(或者波束恢复进程)进行任何标准化工作。因此，支持面向TRP的链路恢复进程，实现在multi-TRP传输场景中各TRP链路的快速恢复，尤其是在终端设备接收到TRP发送的响应后对空域信息的更新是亟待解决的问题。
为了解决上述问题，本申请提出了一种资源更新方法，终端设备接收第一物理下行控制信道PDCCH，所述第一PDCCH承载于所述终端设备推荐的波束信息对应的波束；终端设备在第一时长内，基于所述波束信息更新第一资源，所述第一资源包括第一信道和/或第一信号的空域信息。本申请提供一种更新信道和/或信号资源空域信息的技术方案，使得终端设备在接收到作为响应的第一PDCCH后，根据终端设备推荐的波束信息更新信道和/或信号资源空域信息，从而提升系统性能。
为了使本技术领域的人员更好地理解本申请方案，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、完整地描述，显然，所描述的实施例仅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做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。
请参阅图2，图2为本申请实施例提供的一种资源更新方法的流程示意图，应用于如图1所示的通信系统。如图2所示，该资源更新方法包括如下步骤：
S210、终端设备接收第一物理下行控制信道PDCCH，所述第一PDCCH承载于所述终端设备推荐的波束信息对应的波束。
其中，所述终端设备支持multi-TRP传输，即一个DCI中可以包括多个TRP相应的QCL配置。PDCCH配置由CORESET和搜索空间集合的配置两部分组成。CORESET主要配置PDCCH所在的资源位置，包括频域资源，资源映射方式，资源粒子组捆绑(REG bundle)大小等。搜索空间集合主要配置搜索空间集合的检测周期、检测偏移值、检测时间长度，聚合等级，以及每个聚合等级的PDCCH候选集合数量等。
在一种可能的实施例中，所述第一PDCCH为小区无线网络临时标识C-RNTI或MCS-C-RNTI加扰的PDCCH；
所述终端设备接收第一物理下行控制信道PDCCH，包括：所述终端设备接收RecoverySearchSpaceId，从所述RecoverySearchSpaceId对应的搜索空间中确定所述第一 PDCCH。
其中，终端设备在发送PRACH后，等待TRP发送的波束失败恢复响应，该波束失败恢复响应包括TRP在波束失败恢复时，由较高层参数recoverySearchSpaceId所提供的搜索空间中发送小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)或调制与编码策略小区无线网络临时标识(Modulation and Coding Scheme Cell Radio Network Temporary Identifier，MCS-C-RNTI)加扰的PDCCH，当从搜索空间中检测到C-RNTI或MCS-C-RNTI加扰的PDCCH时，认为Beam Failure Recovery Request发送成功，波束失败恢复过程BFR成功完成。
需要说明的是，上述recoverySearchSpaceId可以是发生BFR的TRP配置的，也可以是其他TRP配置的，本申请实施例对此不做限定。
在另一种可能的实施例中，所述第一PDCCH承载下行控制信息DCI，所述DCI调度的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)进程号与第一个PUSCH的HARQ进程号相同，且所述第一PDCCH中的新数据指示符NDI字段指示所述DCI调度的PUSCH为新数据。
其中，PDCCH包含新数据指示符(New Date Indicator，NDI)字段，NDI字段用于标识将要发送的数据是对应于初始发送还是先前数据的重发，当发送新数据时，NDI字段以0->1->0->1...这样的次序来位变；在重发的情况下，NDI字段具有与初始发送的NDI字段相同的值。因此，TRP可以将NDI字段与先前发送的值进行比较来标识是否执行数据重发。
在本申请实施例中，当承载第一PDCCH的DCI调度的PUSCH的HARQ进程号与第一个PUSCH的HARO进程号相同，且第一PDCCH中有一个翻转的NDI字段值时，即第一PDCCH的NDI字段值与前一个PDCCH的NDI字段值相反时，则认为Beam Failure Recovery Request发送成功，波束失败恢复过程BFR成功完成。
S220、终端设备在第一时长内，基于所述波束信息更新第一资源，所述第一资源包括第一信道和/或第一信号的空域信息。
具体地，终端设备接收到TRP对Beam Failure Recovery Request的响应，即第一PDCCH后，在满足一定的时间后，根据Beam Failure Recovery Request中携带的终端设备维护的备份波束的波束信息，更新第一信道和/或第一信号的空域信息。
可选的，所述第一信道和/或所述第一信号对应的TRP与所述波束信息对应的参考信号RS关联的TRP相同。
其中，TRP可以通过无线资源控制(Radio Resource Control，RRC)信令为终端设备配置传输配置指示(Transmission Configuration Indication，TCI)状态和参考信号(Reference Signal，RS)的对应关系。TCI State用于物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的DMRS的QCL指示或PDCCH的DMRS的QCL指示，也即指示PDCCH或PDSCH所使用的下行波束。每个TCI State对应一个或多个RS Set，每个RS Set包括多个RS资源(也即RS Resource)。每个RS Set与一个DMRS端口组(即DMRS port group)具有QC L关系，例如，一个TRP使用一个DMRS端口组，该DMRS端口组与一个RS Set具有QCL关系。具体的，当TCI用于PDCCH的QCL指示时，通过RRC信令或者RRC和媒体访问控制(Medium Access Control，MAC)控制单元(Control Element，CE)来通知1个 TCI State，指示一个RS Set，该RS Set与PDCCH的DMRS端口具有QCL关系，从而终端设备根据该TCI State即可获知使用哪个接收波束(即Rx Beam)来接收PDCCH。
在本申请实施例中，终端设备接收到TRP发送的第一PDCCH后，终端设备只更新与波束信息对应RS关联同一个TRP的信道和/或信号的空域信息，实现物理信道和/或信号的空域信息的有效更新，避免属于另一个TRP的物理信道和/或信号也进行更新，从而提升系统性能。
可选的，所述第一信道包括以下至少一项：物理上行控制信道PUCCH、物理下行共享信道PDSCH、物理上行共享信道PUSCH、第一控制资源集COERSET、CORESET#0，所述第一COERSET为发生波束失败的辅小区对应的CORESETs。
具体地，第一COERSET为携带Scell波束失败信息的MAC CE中所指示的Scell上所有的CORESETs，CORESET#0为Scell和/或Pcell中索引号为0的CORESET。在接收到第一PDCCH后，终端设备可以更新与波束信息对应的RS关联同一个TRP的PUCCH、PDSCH、PUSCH、第一COERSET、CORESET#0中的至少一种。
可选的，所述第一信号可以包括探测参考信号(Sounding Reference Signal，SRS)，所述SRS的用途配置包括码本codebook或非码本non-codebook。
其中，SRS的用途配置包括波束管理(beam management)，天线轮询(antenna switching)，基于码本的传输(codebook)，基于非码本的传输(non-codebook)中的至少两种。在本申请实施例中，在发生BFR后，终端设备可以基于波束信息更新SRS，该SRS的用途配置为基于码本codebook或非码本non-codebook的传输。
可选的，所述第一时长为所述第一PDCCH的最后一个符号之后的预设位置的符号至所述第一资源配置或激活的时长。
具体地，第一时长可以为终端设备接收到第一PDCCH的最后一个符号之后的预设位置的符号至第一资源全部或部分配置的时长，或者，第一时长可以为终端设备接收到第一PDCCH的最后一个符号之后的预设位置的符号至第一资源全部或部分激活的时长。其中，重新部分配置或部分激活第一资源可以表示为TRP重新配置或激活PUCCH、PDSCH、PUSCH、第一控制资源集COERSET、CORESET#0、SRS的空域信息中的任意一种或多种。
进一步地，该预设位置可以是设计者预设设计的，也可以是根据协议规定的，例如，该预设位置可以为12、16、18、24、28、30、32等等，本申请实施例对此不做限定。
可以看出，本申请提出了一种资源更新方法，终端设备接收第一物理下行控制信道PDCCH，所述第一PDCCH承载于所述终端设备推荐的波束信息对应的波束；终端设备在第一时长内，基于所述波束信息更新第一资源，所述第一资源包括第一信道和/或第一信号的空域信息。本申请提供一种更新信道和/或信号资源空域信息的技术方案，使得终端设备在接收到作为响应的第一PDCCH后，根据终端设备推荐的波束信息更新信道和/或信号资源空域信息，从而提升系统性能。
