本申请涉及通信技术领域，尤其涉及通信***中的基于波束通信的技术，具体地涉及通信***中资源配置的方法、装置及***。
背景技术
在移动通信***中使用波束进行传输，即通过在空间上朝向特定的方向发送信号，可以实现更高的天线阵列增益。波束可以通过波束成型(Beamforming)等技术手段实现。例如在高频(high frequency,HF)通信中的一个重要的方向就是模拟加数字混合波束成型(hybrid Beamforming)，这样既可以很好的对抗高频信号由于传输距离导致的损耗又可以把复杂度和硬件成本控制在可接受的范围内。
在基于波束的通信***中，为了获得波束增益，发射端会将信号朝特定方向集中发射，而接收端会调整接收波束模式，尽量获取更多的信号能量。然而，随着由于移动、遮挡或信道干扰环境改变，正在通信的一对收发波束的通信质量可能下降，甚至无法正常通信。为了解决由于波束通信质量下降造成的波束失败，用户设备(User Equipment，简称UE)需要对波束进行检测，当UE物理层在一个波束检测区间(可以对应一个上报周期)内确定被检测的波束不满足预定条件，产生波束失败实例，则将按照上报周期上报给UE的高层。当被检测的波束持续不满足预定条件(即，波束失败实例持续产生)时，UE即可确认波束失败发生，并进入波束恢复流程，波束恢复流程包括候选波束集合中新波束的识别、波束失败恢复请求和波束失败应答接收等步骤。
针对波束恢复的流程，目前使用物理随机接入信道(physical random access channel，简称PRACH)资源进行波束恢复，PRACH资源的最短周期为10ms，对于拥有快速波束恢复需求的***(例如时延敏感的***)，基于PRACH资源的波束恢复时间过长。另外，PRACH的资源配置不够灵活，在一些带宽部分(bandwidth part，简称BWP)或载波分量(ComponentCarrier，简称CC)上，可能网络设备没有配置PRACH资源。相比之下，物理上行控制信号(physical uplink control channel，简称PUCCH)资源具有更高的灵活性，然而，使用PUCCH资源进行波束恢复的问题在于，正常情况下PUCCH的收发波束已经确定，在发生波束失败时，PUCCH的上行波束可能已经无法通信，无法保证基站可以成功接收波束失败恢复的请求。

本申请中基于波束的通信，是指在移动通信***中使用波束进行传输，即通过在空间上朝向特定的方向发送信号，可以实现更高的天线阵列增益。波束可以通过波束成型(Beamforming)等技术手段实现。例如在高频(high frequency,简称HF)通信中的一个重要的研究方向就是模拟加数字混合波束成型(hybrid Beamforming)，这样既可以很好的对抗高频信号由于传输距离导致的损耗又可以把复杂度和硬件成本控制在可接受的范围内。
本申请所涉及的技术中，相关术语定义如下：
准同位(quasi-co-location，简称QCL)：准同位关系用于表示多个资源之间具有一个或多个相同或者相类似的通信特征，对于具有准同位关系的多个资源，可以采用相同或者类似的通信配置。例如，如果两个天线端口具有准同位关系，那么一个端口传送一个符号的信道大尺度特性可以从另一个端口传送一个符号的信道大尺度特性推断出来。大尺度特性可以包括：延迟扩展，平均延迟，多普勒扩展，多普勒频移，平均增益，接收参数，终端设备接收波束编号，发射/接收信道相关性，接收到达角，接收机天线的空间相关性，主到达角(Angel-of-Arrival，AoA)，平均到达角，AoA的扩展等。具体地，准同位指示用于指示至少两组天线端口是否具有准同位关系为：所述准同位指示用于指示所述至少两组天线端口发送的信道状态信息参考信号是否来自相同的传输点，或所述准同位指示用于指示所述至少两组天线端口发送的信道状态信息参考信号是否来自相同的波束组。
准同位假设(QCL assumption)：是指假设两个端口之间是否具有QCL关系。准同位假设的配置和指示可以用来帮助接收端进行信号的接收和解调。例如，接收端能确认A端口和B端口具有QCL关系，即可以将A端口上测得的信号的大尺度参数用于B端口上的信号测量和解调。
波束(beam)：波束是一种通信资源。波束可以是宽波束，或者窄波束，或者其他类型波束。形成波束的技术可以是波束成形技术或者其他技术手段。波束成形技术可以具体为数字波束成形技术，模拟波束成形技术，混合数字/模拟波束成形技术。不同的波束可以认为是不同的资源。通过不同的波束可以发送相同的信息或者不同的信息。可选的，可以将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或多个天线端口，用于传输数据信道，控制信道和探测信号等，例如，发射波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。可以理解的是，形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。波束在协议中的体现还是可以空域滤波器(spatial filter)。
波束的信息可以通过索引信息进行标识。可选地，所述索引信息可以对应配置UE的资源标识，比如，所述索引信息可以对应配置的信道状态信息参考信号(Channel status  information Reference Signal，简称CSI-RS)的ID或者资源，也可以对应配置的上行探测参考信号(Sounding Reference Signal，简称SRS)的ID或者资源。或者，可选地，所述索引信息也可以是通过波束承载的信号或信道显示或隐式承载的索引信息，比如，所述索引信息可以是通过波束发送的同步信号或者广播信道指示该波束的索引信息。
或者，可选地，波束的信息的标识包括可以通过波束的绝对索引、波束的相对索引，波束的逻辑索引，波束对应的天线端口的索引，波束对应的天线端口组的索引，下行同步信号块的时间索引，波束对连接(beam pair link,BPL)信息，波束对应的发送参数(Tx parameter)，波束对应的接收参数(Rx parameter)，波束对应的发送权重(weight)，权重矩阵(weight vector)，权重向量(weight matrix)，波束对应的接收权重，或者它们的索引，波束对应的发送码本(codebook)，波束对应的接收码本，或者它们的索引。
空域准同位(spatial QCL)：spatial QCL可以认为是QCL的一种类型。对于spatial有两个角度可以理解：从发送端或者从接收端。从发送端来看，如果说两个天线端口是空域准同位的，那么是指这两个天线端口的对应的波束方向在空间上是一致的。从接收端来看，如果说两个天线端口是空域准同位的，那么是指接收端能够在相同的波束方向上接收到这两个天线端口发送的信号。
图1给出了本申请涉及的一种网络***架构，本申请适用于如图1所示的基于波束300的多载波通信***，例如5G新空口(New Radio，简称NR)。该***中包括通信***中的上行(UE200到接入节点100)和下行(接入节点100到UE200)通信。根据长期演进(Long Term Evolution，简称LTE)/NR的协议，在物理层，上行通信包括上行物理信道和上行信号的传输。其中上行物理信道包括随机接入信道(Random access channel，简称为PRACH)，上行控制信道(Physical uplink control channel，简称为PUCCH)，上行数据信道(Physical uplink shared channel，简称为PUSCH)等，上行信号包括信道探测信号SRS，上行控制信道解调参考信号(PUCCH De-modulation Reference Signal，简称PUCCH-DMRS)，上行数据信道解调参考信号PUSCH-DMRS，上行相位噪声跟踪信号(phase noise tracking reference signal,简称PTRS)等。下行通信包括下行物理信道和下行信号的传输。其中下行物理信道包括广播信道(Physical broadcast channel，简称PBCH)，下行控制信道(Physical downlink control channel，简称PDCCH)，下行数据信道(Physical downlink shared channel，简称PDSCH)等，下行信号包括主同步信号(Primary Synchronization Signal，简称PSS)/辅同步信号(Secondary Synchronization Signal，简称SSS)，下行控制信道解调参考信号PDCCH-DMRS，下行数据信道解调参考信号PDSCH-DMRS，相位噪声跟踪信号PTRS，信道状态信息参考信号(Channel status information reference signal，CSI-RS)，小区信号(Cell Reference Signal，简称CRS)(NR没有)，精同步信号(Tim/frequency tracking Reference Signal，简称TRS)(LTE没有)等。
在NR中，下行信道所使用的波束或参考信号发送对应的波束的波束指示是通过关联传输配置指示(Transmission Configuration Indicator，简称TCI)状态表中的参考资源索引实现的。
对于上行传输，NR尚未定义空间准同位关系，上行的波束指示直接通过参考信号 资源标识实现：
在上行和下行通信中，当下行物理信道的发射波束与接收波束之间的通信质量恶化后，波束失败可能发生。在NR协议中，在一个波束检测区间(可以对应一个上报周期)内，当所有需要检测的下行物理信道的波束质量低于某一门限时，可以视作一次波束失败实例；需要说明的是UE通过波束检测信号实现对波束的检测，对于至少一个波束检测信号，UE在检测之前已经获知各波束检测信号的周期，所以UE知道在当前波束检测区间内哪些波束检测号到来需要检测，UE检测需要检测的波束检测信号；连续波束失败实例达到最大次数时(最大次数可以由接入节点100配置，也可以由协议规定具体值)，可以确定波束失败发生。
本申请中，在图1所示的***下，接入节点100可以通过高层信令，例如无线资源控制(Radio Resouce Control，简称RRC)信令为UE200配置一个集合

用于波束失败检测，需要说明的，该集合也可以不由接入节点100配置，而由UE200根据下行物理信道，如下行控制信道的TCI指示自行确定。该集合中可选包含一个或多个周期性的CSI-RS资源索引；接入节点100还为UE配置用于波束失败恢复的物理上行控制信道PUCCH资源，该PUCCH资源包括对应的PUCCH的传输波束，PUCCH资源可以为一个或多个。可选的，接入节点100还可通过高层信令(如RRC)为UE200配置一个集合

作为候选波束集合(该集合也可以由UE200自行确定)，该集合中可选包含CSI-RS资源索引和/或SSB的资源索引。可选的，接入节点100通过高层信令(如RRC)为UE200配置最大波束失败实例个数N(该个数N也可不由接入节点100配置，而由协议规定具体值)，波束失败后的候选波束门限Qin，以及UE200波束恢复的随机接入信道(Random Access Channel，简称RACH)信息、候选波束对应的RACH资源、用于检测波束失败恢复应答的控制资源集合(control resource set)等。除此之外，高层信令还包含一些其他配置信息，包括波束恢复计时器、波束恢复应答计时器，波束恢复请求的最大传输次数。当接入节点100没有配置集合
Figure PCTCN2019088686-appb-000003
时，UE200应根据当前被要求检测的下行物理信道(如PDCCH)所对应的TCI状态来决定
Figure PCTCN2019088686-appb-000004
以包括与该信道(如PDCCH)具有空间QCL关系的SSB和/或周期性CSI-RS。门限Qin为CSI-RS的物理层参考信号接收功率(Layer 1-Reference Signal Received Power，简称L1-RSRP)门限，SSB的门限可以通过高层信令中的powerControlOffsetSS(即PC_ss，表示CSI-RS资源元素与SSB的资源元素的功率偏差)结合Qin推断。
以下行控制信道PDCCH为例，UE200使用

中与PDCCH的DMRS满足空间准同位关系的RS对控制信道的质量进行评估。具体的，UE200使用满足条件的RS对PDCCH的块误码率(Block Error Rate，简称BLER)进行估算(PDCCH-hypothetical-BLER)，在一个波束检测区间(可以对应一个上报周期)内当所有需被检测的下行控制信道的hypothetical-BLER大于门限值(例如，可以为0.1)时，UE200物理层确认一次波束失败实例，并按照指定周期上报给UE200侧MAC层。
UE200侧MAC层对物理层上报的波束失败实例进行计数。当波束失败实例连续发生次数达到接入节点100配置的最大值N时，MAC可以判定为波束失败发生，开启波束失败恢复计时器，并通知UE200物理层波束失败发生。收到MAC层波束失败的指示后，可选的，UE200物理层上报集合
Figure PCTCN2019088686-appb-000006
中满足候选波束门限Qin的参考信号的波束测量结果，上报形式为一组或多组{波束RS索引,L1-RSRP测量结果}。UE200的MAC层根据物理层上报的测量结果和波束，按照某种规则选择一个候选波束的RS索引，并根据这个RS索引确定对 应的PUCCH资源，并将选择后的波束索引q new与其对应的PUCCH资源反馈给物理层。UE200的物理层根据接入节点100预配置或规范预定义的PUCCH周期，在指定的PUCCH资源上使用对应的PUCCH传输波束向接入节点100发送波束失败恢复请求(Beam-failure-recovery-request)。在发送波束失败恢复请求预定个时隙后，UE200使用qnew对应波束对高层信令分配的用于波束失败恢复应答的控制资源集CORESET进行监测，应答内容为使用C-RNTI扰码加扰的可能的下行控制信息(DCI)。若成功获取应答，则波束恢复成功，进入正常波束管理流程。若在一定时间窗口内未能成功收到有效的应答，则再次从发送波束恢复请求开始重复前述过程，直到达到最大波束恢复请求次数或波束失败恢复计时器超时。
以上，实现了在该***中波束失败检测和恢复的流程。需要说明的是，图1所示的仅是本申请所涉及的一种网络***架构的示例，本申请并不局限于此。
实施例一
为了能够灵活有效地进行波束失败恢复，接入节点为UE配置用于波束失败恢复的PUCCH资源，本实施例中以不限一个PUCCH资源为例进行描述，需要说明的是，本实施例及后续实施例皆以UE与接入节点之间交互进行描述，仅为示例性描述，本申请不限于此，在网络中接入节点管理下的传输接收点TRP具备部分接入节点的相关功能时，本申请还可以应用在UE与TRP交互的场景下。根据本申请的实施例，图2为本申请提供的一种资源配置的方法的第一个实施例的流程图，为了便于方案理解，在描述时，本实施例及后续实施例皆以UE和接入节点双侧的行为展开，从交互多方的角度进行整体描述，但绝非限定***中改进在于交互各侧的步骤必须合在一起执行，本申请提出的技术方案，在***中每一侧均有改进。
该方法包括：
S101、接入节点向UE发送用于波束失败恢复的物理上行控制信道PUCCH的资源配置，所述PUCCH的资源配置包括对应PUCCH的传输波束。
可选的，所述PUCCH的资源配置还可以包括以下至少一项：所述PUCCH的通信资源(如，PUCCH对应的时域资源、频域资源、和/或码域资源，例如发送用于波束失败恢复的PUCCH使用的掩码等)、所述PUCCH的时间偏移量、所述PUCCH的格式、所述PUCCH的周期。进一步可选的，所述PUCCH的资源还包括：所述传输波束的使用时间与所述PUCCH的周期的关联关系，和/或所述传输波束的使用时间与所述PUCCH的时间偏移量的关联关系。需要说明的是，传输波束的使用时间，即使通过传输波束进行下行信号传输的时间。
进一步可选的，传输波束除了和周期/偏移量关联之外。还可以与以下信息关联：PUCCH起始符号、符号长度、起始时隙、时隙长度、起始频域位置、频域资源大小、扰码序列、正交掩码序列、循环移位序列、循环移位跳跃方法、相位旋转大小、序列跳跃方法、有效比特数目、编码方法、码率、跳频图案、调制方法、调制方法的阶数、波形、发送功率、PUCCH格式、PUCCH内容等，所以，PUCCH的资源配置还可以包括这些信息和/或这些信息与传输波束的关联关系。
可选的，PUCCH包括长PUCCH，例如占4-14个OFDM符号，短PUCCH，例如占1-2个OFDM符号。PUCCH可以在一个时隙内传输，也可以跨时隙传输。起始符号，符号数和时隙数都是可配置的。
PUCCH能承载不同的比特数，从0个，1个，2个到多个。其中，0个比特是指信号的有无，而信号本身不携带有效信息。PUCCH的编码方法和码率都是可配置的。
PUCCH的传输序列可以配置序列跳跃(sequence hopping)和循环移位跳跃(cyclic shift hopping)。
PUCCH的频率资源可以配置跳频(frequency hopping)方法或跳频图案。即终端在不同时间使用不同的频率资源传输PUCCH以获得频域多样性。跳频方法包括时隙内跳频和时隙间跳频。
PUCCH的传输序列可以配置加扰、掩码等操作来区分不同的终端。即不同终端使用不同的扰码、正交的掩码等达到在収端区分终端的目的。
PUCCH的传输可以使用不同的调制方式，例如二进制相移键控(binary phase shift keying，简称BPSK),Pi/2BPSK,正交相移健控(quadrature phase shift keying，简称QPSK)等。
PUCCH的传输可以使用不同的波形，例如循环前缀正交频分复用(cyclic prefix Orthogonal Frequency Division Multiplexing，简称为CP-OFDM),离散傅立叶变换扩展OFDM(discrete Fourier transform spread OFDM，简称DFT-s-OFDM)等。
PUCCH的发送功率是终端根据基站指示进行计算的。基站指示的信息包括路损，功率累积参数等。
PUCCH可以用于不同的用途，例如发送调度请求，发送混合自动重传请求(Hybrid Automatic Repeat reQuest，简称HARQ)确认(Acknowledgement，简称ACK)/非确认(negative ACK，简称NACK)信息，发送CSI信息等。本发明中也用PUCCH发送波束失败恢复请求。
用于不同用途的PUCCH可以复用。例如一个PUCCH可以发送调度请求+HARQ ACK。本发明中一个PUCCH可以用于发送波束失败恢复请求+CSI(即波束上报)。
当基站无法区分PUCCH的用途时，例如调度请求和波束失败恢复请求可能具有相同的比特长度。可以引入进一步的区分方法，例如调度请求和波束失败恢复请求使用不同扰码、掩码、cyclic shift、发送功率，跳频图案等。也可以引入进一步的信息交互，例如基站下发下行控制信道调度终端进行上行传输，要求终端在上行传输中携带表明PUCCH用途的信息。
可选的，所述PUCCH的资源配置包括PUCCH的通信资源，PUCCH的通信资源可以与候选波束集合

(网络侧配置的用于波束失败恢复的波束集合)中候选波束对应的下行信号资源相关联，还可以与一个或多个上行信号(如SRS)的资源相关联。所述PUCCH通信资源可以为一个或者多个。对于PUCCH通信资源为多个的情况，可以一对一关联

中的各波束对应的下行信号的资源，和/或一对一关联上行信号的资源。可选的，对于PUCCH通信资源为多个的情况，也可以部分PUCCH通信资源一对一关联

中的各波束对应的下行信号的资源和/或一对一关联所述上行信号的资源，一个或部分PUCCH通信资源中每一个PUCCH通信资源是一对多关联
Figure PCTCN2019088686-appb-000010
中的各波束对应的下行信号的资源，和/或一对多关联上行信号的资源。对于多个PUCCH通信资源中存在一对多关联的配置方式，与只有一个PUCCH通信资源的情况下进行配置的方式类似，在本实施例中不进行展开，将在后续实施例中进行针对性描述。本实施例中各配置关系表中的示例以PUCCH通信资源为多个的情况进行描述，包括多个PUCCH通信资源一对一关联所述下行信号或所述上行信号、多个 PUCCH通信资源中部分PUCCH通信资源一对一关联所述下行信号和/或所述上行信号。示例性的，针对全部或部分PUCCH通信资源一对一关联下行信号的配置方式，具体的下表给出了PUCCH通信资源(resource)分别关联了候选波束集合中的参考信号{CSI-RS resource#x和CSI-RS resource#y}：
表1
PUCCH resource 下行信号
PUCCH resource#x CSI-RS resource#x
PUCCH resource#y CSI-RS resource#y
… …
根据表1的配置，PUCCH resource#x的通信资源以CSI-RS resource#x的通信资源为参考，PUCCH resource#y的通信资源以CSI-RS resource#x的通信资源为参考。
此外，对于PUCCH的资源配置包括的UE发送该PUCCH使用的所述PUCCH的传输波束的信息，示例性的可以如表2的配置：
表2
PUCCH resource UE发送波束指示(PUCCH spatial info)
PUCCH resource#x CSI-RS resource#x
PUCCH resource#y CSI-RS resource#y
… …
在表2中，PUCCH的传输波束(即，发送波束)指示由下行参考信号RS的资源索引表示，这表明接入节点希望UE使用接收该下行RS的接收波束对应的发送波束来发送用于波束失败恢复请求的PUCCH。PUCCH spatial info也可以配置成其他的下行RS(如同步信号块，跟踪信号等)或者上行信号(如探测信号SRS等)，如果配置成关联上行信号，这表明接入节点希望UE根据之前训练过的该上行信号的发送波束来发送用于波束失败恢复请求的PUCCH，具体配置可以示例性的如表3所示：
表3
PUCCH resource UE发送波束指示(PUCCH spatial info)
PUCCH resource#x SRS resource#x
PUCCH resource#y SRS resource#y
… …
需要说明的，如果PUCCH通信资源一对一关联上行信号，接入节点可以直接配置PUCCH关联到上行信号资源。这种关联关系包括PUCCH的波束信息配置为SRS资源(如表3)。对于PUCCH的通信资源，可以不进行限制，可选的，可以如表1的配置方式，关联下行信号；可选的，可以与上行信号的通信资源相关联。
S102、UE检测到波束失败事件并检测新可用波束。
以下行控制信道PDCCH为例，UE使用接入节点配置的用于波束失败检测的集合
Figure PCTCN2019088686-appb-000011
中与PDCCH的DMRS满足空间准同位关系的RS对控制信道的质量进行评估。具体的，UE200 使用满足条件的RS对PDCCH的块误码率(Block Error Rate，简称BLER)进行估算(PDCCH-hypothetical-BLER)，在一个波束检测区间(可以对应一个上报周期)内当所有需被检测的下行控制信道的hypothetical-BLER大于门限值(例如，可以为0.1)时，确认一次波束失败实例，UE对波束失败实例进行计数。当波束失败实例连续发生次数达到接入节点配置的最大值N时，可以判定为检测到波束失败事件，本实施例不限制UE检测波束失败的具体方法。UE对候选波束集合
Figure PCTCN2019088686-appb-000012
中的波束对应的下行信号进行检测，确认可用新波束，示例性的，本实施例中假设UE确认CSI-RS resource#x代表的下行波束满足通信条件，成为新可用波束。
S103、当UE检测到波束失败事件，UE基于所述PUCCH的资源配置，根据对应PUCCH的周期，向所述接入节点发送波束失败恢复请求。
本实施例中的PUCCH需要具有周期性的特性。特别是基站侧，需要周期性的使用PUCCH通信资源对应的收波束来接收UE可能发送的用于波束恢复请求的PUCCH消息。而在UE侧，则只需要在发生了波束失败事件并确认其可用新波束的时候才会根据PUCCH的周期发送这个PUCCH。可选的，所述PUCCH的周期可以由接入节点配置，可选的所述PUCCH的周期也可以为预置周期，如各类协议、规范给定的周期，进一步可选的，这个周期可以与关联的下行信号资源或上行信号资源本身的周期相关或者与下行信号对应的上报的周期相关。
以PUCCH的资源关联CSI-RS的资源为例，如图3所示，图3给出了UE进行波束失败恢复的通信时机示意图。以关联下行信号中CSI-RS的资源为例，接入节点为UE配置了多个与候选波束集合中的候选波束(CSI-RS resource#x、CSI-RS resource#y)相关联的PUCCH的资源(PUCCH resource#x、PUCCH resource#y)，具体配置方式可以示例性地见S101中的表1和表2，接入节点根据PUCCH resource#x对应的PUCCH#x的周期，周期性地使用CSI-RS resource#x对应的接收波束去监测是否接收到UE发来的波束失败恢复请求；接入节点根据PUCCH resource#y对应的PUCCH#y的周期，周期性地使用CSI-RS resource#y对应的接收波束去监测是否接收到UE发来的波束失败恢复请求。在时刻t时UE检测到波束失败并确认CSI-RS resource#x对应波束为新可用波束，由于PUCCH的资源关联有CSI-RS resource#x的资源，则UE可使用PUCCH#x的资源，用关联CSI-RS resource#x的PUCCH的传输波束，即UE接收CSI-RS resource#x对应的CSI-RS的波束对应的发送波束为PUCCH的传输波束，需要说明的是UE检测到波束失败后，并不一定是立即进行波束失败恢复，而是要根据PUCCH#1的周期，在对应的资源上，使用CSI-RS resource#x收波束对应的发送波束作为PUCCH的传输波束向接入节点发送波束失败恢复请求，和/或通知接入节点新可用波束的信息。由于接入节点配置了PUCCH resource#x，包括通信资源，波束等信息(如序列等)，接入节点能够在发送CSI-RS resource#x的发波束对应的收波束上接收PUCCH resource#x。按照接入节点的配置或预定义，UE反馈的用于波束失败恢复请求的PUCCH可以不包含有效信息(payload)，基站能够通过PUCCH resource#x和CSI-RS resource#x的关联关系确定UE反馈的可用波束是CSI-RS resource#x。或者，按照接入节点的配置或预定义，UE反馈的PUCCH可以包含有效信息，该有效信息表明UE选择的新可用波束是CSI-RS resource#x，同时，UE也可以反馈CSI-RS resource#x对应的波束质量，例如CSI-RS resource#x测得的L1-RSRP。如果PUCCH的传输波束配置成上行信号的发送波束，那么 该示例中，就在相应通信资源上采用对应的上行信号的发送波束向接入节点发送波束失败恢复请求，可进一步指示UE选择的新可用波束的相关信息。
需要说明的是，对于S101中配置的PUCCH传输波束是传输上行信号的波束时，当UE采用传输上行信号的波束中非所述传输波束向接入节点发送波束失败恢复请求，UE还向所述接入节点发送波束信息，所述波束信息用于指示发送所述波束失败恢复请求的波束。
S104、接入节点向UE发送波束失败恢复响应消息。
UE需要检测接入节点的响应，接入节点在收到了UE通过PUCCH上报的波束失败和新可用波束信息后，接入节点可以通过该可用波束向UE发送响应以便向UE确认波束失败的信息和新波束的信息被接入节点成功的接收，并且后续的通信可以基于UE上报的新波束。这个响应可以是一个PDCCH，也可以是PDCCH并且调度了一个PDSCH。可选的，UE使用103发送用于波束失败恢复请求的PUCCH波束对应的接收波束来接收这个接入节点的响应。
需要说明的是，接入节点不一定向UE发送响应，或者说UE不一定在波束失败恢复请求后，收到接入节点的响应，如果在预定时间内未收到响应，则认为所述波束失败恢复请求失败。可选的，波束失败恢复请求在预定时间内可多次发送。
本申请实施例的一种资源配置的方法，通过用于波束失败恢复的PUCCH资源的配置，使得UE能够灵活有效地进行波束失败恢复。
实施例二
图4为本申请提供的一种资源配置的方法的第二个实施例的流程图。与实施例一的区别在于，该实施例针对一个PUCCH通信资源与多个上/下行信号的资源一对多的配置方式，或者多个PUCCH通信资源中，一个或多个PUCCH通信资源中各PUCCH通信资源与多个上/下行信号的资源一对多的配置方式。与实施例一相同或类似的内容在本实施例中不再赘述。需要说明的，为了便于方案理解，在描述时，本实施例以UE和接入节点双侧的行为展开，从交互多方的角度进行整体描述，但绝非限定***中改进在于交互各侧的步骤必须合在一起执行，本申请提出的技术方案，在***中每一侧均有改进。
该方法包括：
S201、接入节点向UE发送用于波束失败恢复的物理上行控制信道PUCCH的资源配置，所述PUCCH的资源配置包括对应PUCCH的传输波束、传输波束的使用时间的相关信息。
可选的，所述PUCCH的资源配置还可以包括以下至少一项：所述PUCCH的通信资源、所述PUCCH的时间偏移量、所述PUCCH的格式、所述PUCCH的周期。进一步可选的，传输波束的使用时间的相关信息包括，所述传输波束的使用时间与所述PUCCH的周期的关联关系，和/或所述传输波束的使用时间与所述PUCCH的时间偏移量的关联关系。
可选的，所述PUCCH的资源配置包括PUCCH通信资源，所述PUCCH通信资源可以与候选波束集合
Figure PCTCN2019088686-appb-000013
中候选波束对应的下行信号资源相关联，还可以与一个或多个上行信号(如SRS)的资源相关联。本实施例中，PUCCH的通信资源一对多的关联下行/上行信号的资源。但是PUCCH的传输波束不限于一个，可以是多个。针对多个情况，示例性的，针对一个PUCCH通信资源(可以是一个PUCCH通信资源中的，或者多个PUCCH通信资源中的，但是一对多的PUCCH通信资源)，PUCCH spatial info可以配置成{CSI-RS resource#x和CSI-RS resource#y}，即在该例子中的配置下，UE有两个可能的发送波束(CSI-RS  resource#x指示的CSI-RS#x的接收波束对应的发送波束、CSI-RS resource#y指示的CSI-RS#y的接收波束对应的发送波束来)，由于本实施例中PUCCH的通信资源为一个，而UE在该一专用通信资源上若使用这两个波束之一进行PUCCH的发送，接入节点无法根据通信资源的不同进行区分，接入节点需要在该一专用PUCCH通信资源上进行接收，判断UE具体使用的是哪个波束，进而保证接入节点能够在正确的方向接收到UE发送的PUCCH。所以，可以将使用波束的时间与PUCCH的周期相关。示例性的，假如，PUCCH的周期为4个时隙(slot)，约定UE只能在slot number mod(2*4)＝0时使用CSI-RS resource#x发送用于波束失败恢复请求的PUCCH，slot number mod(2*4)＝4时使用CSI-RS resource#y发送用于波束失败恢复请求的PUCCH。而相应的，接入节点需要在slot number mod(2*4)＝0时使用CSI-RS resource#x对应的收波束接收PUCCH，slot number mod(2*4)＝4时使用CSI-RS resource#y对应的收波束接收PUCCH。或者，可以说如果基站能在slot number mod(2*4)＝0时使用CSI-RS resource#x对应的收波束收到PUCCH，则可以判断UE反馈的可用波束是CSI-RS resource#x。可以归纳地说，如果PUCCH周期为P，备选波束的参考信号数目为N，那么UE应该在slot number mod(P*N)＝(n-1)*P时使用候选波束集合中的第n个波束对应的发波束进行PUCCH的发送，而接入节点也应该在相应的slot使用候选波束集合中的第n个波束对应的收波束进行接收。其中候选波束集合中的第n个波束可以是按照波束对应的参考信号的标识大小排序的。以上仅为各PUCCH传输波束的使用时间与PUCCH的周期相关的一种示例，本申请不限于此，还可以通过其他形式来来定义各PUCCH传输波束的使用，以区分各波束。再例举一种实现方式，可以将使用波束的时间与PUCCH的时间偏移量(offset)相关，假如，PUCCH的周期为4个slot，约定UE只能在offset＝0时使用CSI-RS resource#x发送用于波束失败恢复请求的PUCCH，offset＝1时使用CSI-RS resource#y发送用于波束失败恢复请求的PUCCH。而相应的，基站需要在slot number mod(2*4)＝0时使用CSI-RS resource#x对应的收波束接收PUCCH，slot number mod(2*4)＝4时使用CSI-RS resource#y对应的收波束接收PUCCH。可以说，如果基站能在slot number mod(2*4)＝0时使用CSI-RS resource#x对应的收波束收到PUCCH，则可以判断UE反馈的可用波束是CSI-RS resource#x。需要说明的，使用不同的offset区分不同的波束也可以适用于实施例一。
对于PUCCH通信资源与上行信号关联的情况，PUCCH的传输波束可以关联上行信号(如已经训练过的波束对应的SRS)的资源，可选的，基于与以上关联下行信号资源(CSI-RS resource)的类似方式，可以通过上行信号的发送波束作为PUCCH的传输波束，根据使用波束的时间与例如PUCCH的周期、时间偏移量等预定关联关系，或者是其他方式，来区分不同的PUCCH的传输波束。可选的，也可以不配置相应关联关系来区分使用波束的时间，而是规定UE使用所有已配置的上行信号资源的发送波束进行轮询，顺序可以依照上行信号资源编号，可选的，可以限制PUCCH的传输波束为用于做波束管理的SRS对应的波束。
S202、UE检测到波束失败事件并检测新可用波束。

本实施例中的PUCCH需要具有周期性的特性。特别是基站侧，需要周期性的使用PUCCH通信资源对应的收波束来接收UE可能发送的用于波束恢复请求的PUCCH消息。而在UE侧，则只需要在发生了波束失败事件并确认其可用新波束的时候才会根据PUCCH的周期发送这个PUCCH。可选的，所述PUCCH的周期可以由接入节点配置，可选的所述PUCCH的周期也可以为预置周期，如各类协议、规范给定的周期，进一步可选的，这个周期可以与关联的下行信号资源或上行信号资源本身的周期相关或者与下行信号对应的上报的周期相关。需要说明的是，如果PUCCH的传输波束是通过与PUCCH的周期的关联关系进行区分，那么就需要根据PUCCH的传输波束与周期的关联关系，发送波束失败恢复请求。
以PUCCH传输波束关联下行信号中CSI-RS的资源为例，根据202发现的CSI-RS resource#x和201中配置的一专用PUCCH通信资源，UE使用CSI-RS resource#x收波束对应的发波束在PUCCH resource#x发送用于波束失败恢复请求的PUCCH，通知接入节点波束失败和/或新可用波束的信息。按照201的接入节点配置，接入节点能够在发送CSI-RS resource#x的发波束对应的收波束上接收PUCCH resource#x。可选的，按照接入节点的配置或预定义，UE反馈的PUCCH可以不包含有效信息(payload)，基站能够通过PUCCH resource#x和CSI-RS resource#x的关联关系确定UE反馈的可用波束是CSI-RS resource#x。可选的，按照基站的配置或预定义，UE反馈的PUCCH可以包含有效信息，该有效信息表明UE选择的新可用波束是CSI-RS resource#x，同时，UE也可以反馈CSI-RS resource#x对应的波束质量，例如CSI-RS resource#x测得的L1-RSRP。如果PUCCH的传输波束配置成上行信号的发送波束，那么该示例中，就在该一专用通信资源上采用上行信号的发送波束向接入节点发送波束失败恢复请求，并可进一步指示UE选择的新可用波束的相关信息。
需要说明的是，对于S201中配置的PUCCH传输波束是传输上行信号的波束时，当UE采用传输上行信号的波束中非所述传输波束向接入节点发送波束失败恢复请求，UE还向所述接入节点发送波束信息，所述波束信息用于指示发送所述波束失败恢复请求的波束。
S204、接入节点向UE发送波束失败恢复响应消息。
UE需要检测接入节点的响应，接入节点在收到了UE通过PUCCH上报的波束失败和新可用波束信息后，接入节点可以通过该可用波束向UE发送响应以便向UE确认波束失败的信息和新波束的信息被接入节点成功的接收，并且后续的通信可以基于UE上报的新波束。这个响应可以是一个PDCCH，也可以是PDCCH并且调度了一个PDSCH。可选的，UE使用103发送用于波束失败恢复请求的PUCCH波束对应的接收波束来接收这个接入节点的响应。
需要说明的是，接入节点不一定向UE发送响应，或者说UE不一定在波束失败恢复 请求后，收到接入节点的响应，如果在预定时间内未收到响应，则认为所述波束失败恢复请求失败。可选的，波束失败恢复请求在预定时间内可多次发送。
本申请实施例的一种资源配置的方法，通过针对用于波束失败恢复的专用PUCCH资源的配置，使得UE能够灵活有效地进行波束失败恢复，并降低了资源占用和开销。
实施例三
图5为本申请提供的一种资源配置的方法的第三个实施例的流程图。与实施例一、实施例二的区别在于，该实施例中使用已有的上行测量信号资源发送用于波束失败恢复请求的PUCCH，与实施例一、实施例二相同或类似的内容在本实施例中不再赘述。需要说明的，为了便于方案理解，在描述时，本实施例以UE和接入节点双侧的行为展开，从交互多方的角度进行整体描述，但绝非限定***中改进在于交互各侧的步骤必须合在一起执行，本申请提出的技术方案，在***中每一侧均有改进。
该方法包括：
S301、接入节点向UE发送用于波束失败恢复的物理上行控制信道PUCCH的资源配置，所述PUCCH的资源配置包括对应PUCCH的传输波束，所述PUCCH的时域资源与上行测量信号的时域资源相同。
需要说明的是，相同包括全部相同或者部分相同。全部相同，可以例如一个时隙内的第14个符号用来发送SRS，一个时隙内的第14个符号用来发送PUCCH。部分相同，可以例如一个时隙内的第14个符号用来发送SRS，一个时隙内的第11-14个符号用来发送PUCCH。
实施例一和二中接入节点需要周期性切换它的接收波束用于接收UE可能发送的波束失败恢复请求。实际中，由于UE的波束失败并不是一个经常发生的事件，所以接入节点大部分时候专门切换接收波束之后不会收到任何有效信息，这样会对上行***性能造成损失。考虑到接入节点会为UE配置周期性的上行测量信号(如SRS)资源，以SRS为例，接入节点本来就会在这些SRS的资源上，特别是OFDM符号上接收SRS，本实施例考虑复用PUCCH到这些OFDM符号。上行测量信号以SRS为例，如图6所示，图6给出了复用PUCCH的资源到上行测量信号的资源的示意图，可见方式1中，配置用于波束失败恢复(beam failure recovery，简称BFR)的PUCCH(即，PUCCH-BFR)与上行测量信号(SRS#1)频分复用(frequency division multiplexing，简称FDM)，方式2中，配置用于波束失败恢复请求的PUCCH(PUCCH-BFR)可以占用上行测量信号(SRS#1)的资源。即方式1中，所述PUCCH的资源配置的时域资源与上行测量信号的时域资源相同，所述PUCCH的资源配置的频域资源与上行测量信号的频域资源不同；而方式2中，所述PUCCH的资源配置的时频资源与上行测量信号的时频资源相同。
示例性的，与实施例一类似的，候选波束的参考信号为{CSI-RS resource#x和CSI-RS resource#y}。本实施例配置的PUCCH资源和一个或多个SRS的资源频分复用，或者占用一个或多个SRS的资源，PUCCH的传输波束与其频分复用/占用的一个或多个SRS的资源一致。上行测量信号以SRS为例，如图7所示，图7给出了复用PUCCH的资源到上行测量信号的资源的PUCCH传输波束示意图，图7中，PUCCH的传输波束与其频分复用/占用的一个或多个SRS的资源对应的SRS传输波束一致。图7仅为示例，PUCCH的传输波束不一定与SRS传输波束一致，可选的，PUCCH的传输波束可以包括候选波束集合中传 输下行信号的候选波束对应的上行发送波束。
需要说明的是，对于PUCCH资源的时频资源与上行测量信号的时频资源相同的情况，PUCCH的传输不一定优先抢占上行测量信号的传输，可以根据接入节点配置或者预定义的优先级，确定PUCCH的传输是否抢占上行测量信号的传输。
S302、UE检测到波束失败事件并检测新可用波束。
与实施例一、实施例二类似，在此不再赘述，可参见实施例一、实施例二的描述。
S303、当UE检测到波束失败事件，UE基于所述PUCCH的资源配置，根据对应PUCCH的周期，向所述接入节点发送波束失败恢复请求。
假设S302中UE检测的新可用波束为CSI-RS resource#x，UE根据CSI-RS resource#x、301中配置的与上行测量信号资源频分复用/占用上行测量信号资源的PUCCH资源和对应的上行测量信号的发波束发送波束失败恢复请求(可选的，PUCCH的传输波束不一定是上行测量信号的发送波束，还可以包括候选波束集合中传输下行信号的候选波束对应的上行发送波束)，通知接入节点波束失败和/或新可用波束的信息。或者，按照接入节点的配置或预定义，UE反馈的PUCCH可以包含有效信息，该有效信息表明UE选择的新可用波束是CSI-RS resource#x，同时，UE也可以反馈CSI-RS resource#x对应的波束质量，例如CSI-RS resource#x测得的L1-RSRP。
需要说明的是，对于PUCCH传输需要占用上行测量信号传输资源的情况，如果上行测量信号传输的优先级高于PUCCH传输，那么当UE检测到波束失败事件，基于所述PUCCH的资源配置，根据对应PUCCH的周期，要进行PUCCH传输时，恰有上行测量信号要进行传输，那么UE不向接入节点发送波束失败恢复请求，等待下一合适时机再传。
S204、接入节点向UE发送波束失败恢复响应消息。
UE需要检测接入节点的响应，接入节点在收到了UE通过PUCCH上报的波束失败和/或新可用波束信息后，接入节点可以通过该可用波束向UE发送响应以便向UE确认波束失败的信息和新波束的信息被接入节点成功的接收，并且后续的通信可以基于UE上报的新波束。这个响应可以是一个PDCCH，也可以是PDCCH并且调度了一个PDSCH。UE应该使用302选择的新可用波束CSI-RS resource#x的接收波束来接收这个接入节点的响应。
需要说明的是，接入节点不一定向UE发送响应，或者说UE不一定在波束失败恢复请求后，收到接入节点的响应，如果在预定时间内未收到响应，则认为所述波束失败恢复请求失败。可选的，波束失败恢复请求在预定时间内可多次发送。
本申请实施例的一种资源配置的方法，通过全部或部分复用上行测量信号的资源作为用于波束失败恢复的PUCCH资源的配置方式，使得UE能够灵活有效地进行波束失败恢复，并降低了复杂度和开销。
进一步可选的，针对以上三个实施例，在接入节点配置的PUCCH的传输波束包括上行测量信号的的发送波束的情况下，考虑UE旋转导致发送波束改变的问题，上行测量信号以SRS为例，如图8所示，图8给出UE旋转场景下，PUCCH发送波束调整的示意图，如果UE按照接入节点的配置的SRS发送波束指示发送SRS。即按下表。
SRS resource#1 发送波束#1
SRS resource#2 发送波束#2
并且按照基站配置的PUCCH的发送波束发送PUCCH，PUCCH的发送波束与SRS resource#1对应的发送波束一致，即按下表：
PUCCH resource PUCCH spatial info
PUCCH resource#1 SRS resource#1
在UE旋转后，如图8所示，SRS resource#1对应的发送波束#1的方向已经发生改变，会导致接入节点无法收到用于波束失败恢复的PUCCH传输，根据UE内部调整，UE应该使用SRS resource#2对应的发送波束#2发送该PUCCH传输。也就是说,UE自主重写了PUCCH的发送波束指示，这个信息需要由UE通知接入节点。例如在上行消息中携带调整后使用的用于PUCCH的上行波束信息。根据该示例，需要进一步说明书的是，基于以上三个实施例提供的技术方案中，终端设备当检测到波束失败事件，基于所述PUCCH的资源配置，根据对应PUCCH的周期发送的波束失败恢复请求，其中，基于所述PUCCH的资源配置，可以是全部采用网络设备配置的PUCCH资源进行波束失败恢复，也可以是部分采用或者不采用网络设备配置的PUCCH资源进行波束失败恢复，即终端设备自主决定。
可以理解的，上面所有实施例涉及的所述PUCCH的周期可以是由网络设备配置的，即所述PUCCH的资源配置包括PUCCH的周期，也可以是预置周期，即协议、规范等预定义的。需要说明的是如果基站配置了带有周期性质的上行传输或者上行传输资源，例如周期或半持续的上行探测信号的传输，周期或半持续的调度请求传输，周期或半持续的数据传输，周期或半持续的下行参考信号上报，周期或半持续的随机接入资源，PUCCH的周期也可以复用部分或全部的前述上行传输或者上行传输资源的周期。
上述主要从***各实体之间交互或者实体内部实现流程角度对本申请实施例提供的方案进行了介绍。可以理解的是，各实体，为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。

当需要发送数据时，处理器对待发送的数据进行基带处理后，输出基带信号至射频电路，射频电路将基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发送。当有数据发送到终端设备90时，射频电路通过天线接收到射频信号，将射频信号转换为基带信号，并将基带信号输出至处理器，处理器将基带信号转换为数据并对该数据进行处理。为便于说明，图9中仅示出了一个存储器和处理器。在实际的终端设备产品中，可以存在一个或多个处理器和一个或多个存储器。存储器也可以称为存储介质或者存储设备等。存储器可以是独立于处理器设置，也可以是与处理器集成在一起，本申请实施例对此不做限制。
