本申请主张在2018年3月29日在中国提交的中国专利申请号No.201810272571.9的优先权，其全部内容通过引用包含于此。
技术领域
本公开实施例涉及无线通信技术领域，尤其涉及一种物理下行共享信道(Physical Downlink Shared Channel，简称PDSCH)的接收方法和终端。
背景技术
随着通信技术的发展，通信效率越来越受到关注。下面先介绍几个技术点：
1、关于多天线
长期演进(Long Term Evolution，简称LTE)/LTE的演进版本(LTE-Advanced，简称LTE-A)等无线接入技术标准都是以多输入多输出(Multiple-Input Multiple-Output，简称MIMO)+正交频分复用(Orthogonal Frequency Division Multiplexing，简称OFDM)技术为基础构建起来的。其中，MIMO技术利用多天线系统所能获得的空间自由度，来提高峰值速率与系统频谱利用率。
可以预见，在未来的5G移动通信系统中，更大规模、更多天线端口的MIMO技术将被引入。大规模(Massive)MIMO技术使用大规模天线阵列，能够极大地提升系统频带利用效率，支持更大数量的接入用户。
2、关于高频段
在对4G以后的下一代通信系统研究中，将系统支持的工作频段提升至6GHz以上，最高约达100GHz。高频段具有较为丰富的空闲频率资源，可以为数据传输提供更大的吞吐量。目前3GPP已经完成了高频信道建模工作，高频信号的波长短，同低频段相比，能够在同样大小的面板上布置更多的天线阵元，利用波束赋形技术形成指向性更强、波瓣更窄的波束。因此，将大 规模天线和高频通信相结合，也是未来的趋势之一。
3、关于波束失败恢复(beam failure recovery)机制
在高频段通信系统中，由于无线信号的波长较短，较容易发生信号传播被阻挡等情况，导致信号传播中断。如果采用现有技术中的无线链路重建，则耗时较长，因此引入了波束失败恢复机制，该机制分为下面四个步骤：
(1)终端判定发生波束失败事件。
(2)终端选择候选波束(candidate beam)。
(3)终端发送波束失败恢复请求。
(4)终端监听网络设备为终端配置的用于波束失败恢复的控制资源集(Control Resource Set Beam Failure Recovery，CORESET-BFR)，接收dedicated物理下行控制信道(Physical Downlink Control Channel，PDCCH)，以接收网络设备针对波束失败恢复请求的响应信息。
在波束失败恢复过程中，终端在进行PDSCH的接收时，假设PDSCH DMRS端口与所监听的PDCCH是准共址(Quasi-colocation，简称QCL)的。
现有技术中，没有提及在波束失败恢复过程中监听CORESET-BFR上的PDCCH中的响应时，是否还要监听在波束失败之前网络配置的其它CORESET。当两种CORESET都需要监听时，尚没有方案说明怎么确定PDSCH的QCL参数，以使得终端能够正确接收PDSCH。
发明内容
本公开实施例提供一种PDSCH的接收方法和终端，以解决在波束失败恢复过程中如何正确接收PDSCH的问题。
为了解决上述技术问题，本公开是这样实现的：

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创 造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
请参考图1，本公开实施例提供一种PDSCH的接收方法，应用于终端，包括：
步骤101：在判定发生波束失败事件之后，监听CORESET-BFR上的PDCCH和其他CORESET上的PDCCH，其中，所述COREET-BFR和所述其他CORESET为网络设备为所述终端配置的；以及，
步骤102：根据所述CORESET-BFR上的PDCCH的QCL参数、所述其他CORESET上的PDCCH的QCL参数、调度PDSCH的下行控制信息(Downlink Control Information，DCI)所在的CORESET上的PDCCH的QCL参数，或者，调度PDSCH的DCI中的传输配置指示(Transmission Configuration Indication，TCI)状态信息指示的QCL参数，确定PDSCH的QCL参数，并根据确定的QCL参数，进行PDSCH的接收。
所述其他CORESET为网络设备为所述终端配置的除了COREET-BFR之外的其他COREET。
在本公开实施例中，可以实现在波束失败恢复过程中确定PDSCH的QCL参数，以正确接收PDSCH。
本公开实施例中，所述确定PDSCH的QCL参数的步骤之前，还包括：
接收所述网络设备发送的所述CORESET-BFR和所述其他CORESET的配置信息，所述配置信息中包括用于指示所述CORESET-BFR上的PDCCH的QCL参数的TCI状态信息，以及，用于指示所述其他CORESET上的PDCCH的QCL参数的TCI状态信息。
所述CORESET-BFR用于在波束失败恢复过程中，监听dedicated PDCCH上的gNB response，该response是网络设备(即gNB)对终端发送的波束失败恢复请求反馈的响应信息，所述波束失败恢复请求是在判定发生波束失败事件之后向网络设备发送的，下面内容中将详细说明。
所述其他CORESET用于在正常通信过程中传输PDCCH。在终端判定发生波束失败事件之前，终端监听网络设备配置的CORESET-BFR之外的其它CORESET，以接收PDCCH。
本公开实施例中，所述其他CORESET上的PDCCH的QCL参数，与所 述CORESET-BFR上的PDCCH的QCL参数相同或不同。
本公开实施例中，网络设备通过高层信令向终端发送所述CORESET-BFR和其他CORESET的配置信息。
在相关技术中，网络设备通过无线资源控制(Radio Resource Control，简称RRC)信令为终端配置TCI状态和参考信号(Reference Signal，简称RS)的对应关系。
当TCI用于物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)的准共址(Quasi-colocation，简称QCL)指示时，网络设备为每个控制资源集(Control-resource set,简称CORESET)配置K个TCI状态(K为大于或等于1的整数)，当K>1时，由MAC CE指示1个TCI状态，当K＝1时，不需要额外的MAC CE信令。终端在监听CORESET上的PDCCH时，对CORESET内全部搜索空间(search space)的PDCCH使用相同QCL，即相同的TCI状态。
通过RRC信令或者RRC+MAC CE来通知1个TCI状态，该TCI状态对应的RS set中的RS resource(例如周期CSI-RS resource、半持续CSI-RS resource、SS block等)与UE-specific PDCCH DMRS(解调参考信号)端口是空间QCL的。UE根据该TCI状态即可获知使用哪个接收波束来接收PDCCH。
当TCI用于PDSCH的QCL指示时，网络设备激活2 N个TCI状态(N为大于或等于1的正整数)，然后通过下行控制信息(Downlink Control Information，简称DCI)的N-bit TCI域(field)来通知TCI状态，该TCI状态对应的RS set中的RS resource与要调度的PDSCH的DMRS端口是QCL的。终端根据该TCI状态即可获知使用哪个接收波束来接收PDSCH。对于DCI中存在或不存在TCI域两种情况，当调度偏移(scheduling offset)<＝k(scheduling offset是指从接收DCI到接收该DCI调度的PDSCH之间的时间间隔)，k是预设门限，PDSCH的QCL使用缺省(default)TCI状态，该default TCI state是控制信道QCL指示(indication)，且该控制信道QCL indication是由所在时隙(slot)中具有最小ID的CORESET的TCI状态来确定。
对于PDCCH和PDSCH的初始TCI状态，在初始RRC配置和MAC CE 激活TCI states之间，PDCCH DMRS和PDSCH DMRS与初始接入确定的同步信号块(SSB)是空间QCL的。
下面对波束失败恢复过程进行详细说明。
本公开实施例中，终端首先进行波束失败检测(Beam failure detection)：具体的，终端在物理层对波束失败检测参考信号(beam failure detection reference signal，简称BFD RS)进行测量，并根据测量结果来判断是否发生波束失败事件。判断的条件是：如果检测出全部服务控制波束(serving control beam)的metric(hypothetical PDCCH BLER)满足预设条件(超过预设阈值)，则确定为一次波束失败情况(beam failure instance)，终端的物理层上报给终端的高层(MAC层)一个指示，该上报过程是周期的。反之，如果终端的物理层确定没有发生beam failure instance，则不向高层发送指示。终端的高层使用计数器(counter)对物理层上报的指示进行计数，当达到网络配置的最大次数时，终端判定发生了波束失败事件。
终端还需要进行新的候选波束识别(New candidate beam identification)：终端物理层测量候选波束参考信号(candidate beam RS)，寻找新的候选波束(candidate beam)。寻找新的候选波束的步骤不强制在判定波束失败事件发生之后，也可以在判定波束失败事件之前。当终端的物理层收到来自终端的高层(MAC层)的请求或指示或通知时，将满足预设条件(对candidate beam RS的测量质量超过预设L1-RSRP门限)的测量结果上报给终端的高层，上报内容为{beam RS index,L1-RSRP}，终端的高层基于物理层的上报，来选择候选波束。
本公开实施例中，在判定发生波束失败事件且寻找到新的候选波束之后，监听CORESET-BFR上的PDCCH的步骤之前，还包括：向所述网络设备发送波束失败恢复请求(beam failure recovery request)。
具体的，终端的高层(MAC层)根据所选候选波束来确定物理随机接入信道(Physical Random Access Channel，简称PRACH)资源/序列(resource/sequence)。如果终端判断满足波束失败恢复请求(beam failure recovery request)的触发条件，则终端在基于无竞争的PRACH上向网络设备发送上述波束失败恢复请求。终端需要根据网络设备配置的波束失败恢复 请求的发送次数和/或计时器(timer)来发送波束失败恢复请求。此处的无竞争PRACH资源，与其它PRACH资源(如用于初始接入的PRACH资源)可以是频分复用(Frequency Division Multiplexing，简称FDM)或码分复用(code division multiplexing，简称CDM)，其中CDM的PRACH前导码(preambles)要有相同的序列设计。
本公开实施例中，在向网络设备发送波束失败恢复请求之后，终端监听网络设备针对波束失败恢复请求的响应信息(UE monitors gNB response for beam failure recovery request)，网络设备接收到该波束失败恢复请求后，会在配置的用于波束失败恢复的控制资源集(CORESET-BFR)上的专用(dedicated)PDCCH中发送响应(response)，并携带小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)，并还有可能包括切换至新候选波束、或重新启动波束搜索、或其它指示。CORESET-BFR与终端找到的候选波束的下行参考信号(DL RS)是空间QCL的。如果波束失败恢复不成功，则终端的物理层向终端的高层发送一个指示，供高层确定后续的无线链路失败过程。
即，所述监听CORESET-BFR上的PDCCH的步骤包括：监听所述CORESET-BFR上的PDCCH中的响应信息，所述响应信息为所述网络设备根据所述波束失败恢复请求反馈的响应信息。
本公开实施例中，所述监听CORESET-BFR上的PDCCH和其他CORESET上的PDCCH的步骤包括：
在所述网络设备配置的监听窗口(window)内，监听所述CORESET-BFR上的PDCCH中的响应信息；
在所述监听窗口内和/或所述监听窗口之外，监听所述其他CORESET上的PDCCH。
具体的，终端在发送波束失败恢复请求的约定时长之后，在网络设备配置的监听窗口内监听CORESET-BFR上的dedicated PDCCH中的gNB response，以便确认波束失败恢复是否成功。
其他CORESET可以在监听窗口内监听，也可以在监听窗口之外监听，或者一直监听。
下面对本公开实施例中，确定PDSCH的QCL参数的方法进行详细说明。
本公开实施例中，可以根据接收到DCI和接收到所述DCI调度的PDSCH之间的时间间隔(也称为调度偏移，scheduling offset)与预设门限的大小关系，确定采用不同的方式接收PDSCH。
