相关技术中，当网络侧在小区和/或BWP(bandwidth part，带宽部分)上配置了信道或参考信号时，通常会为信道或参考信号配置相应的波束信息，对于下行信道或参考信号会配置TCI(Transmission Configuration Indication，传输配置指示)state(状态)，其中的QCL(Quasi-colocation，准共址)信息包括：BWP-Id(标识)和reference signal(源参考信号)等；对于上行信道或参考信号会配置spatial relation(空间关系)信息，其中包括BWP-Id和reference signal等。

具体实施方式
为使本公开的实施例要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
LTE(Long Term Evolution，长期演进)/LTE-A(LTE-Advanced，长期演进的演进)等无线接入技术标准都是以MIMO(Multiple-Input Multiple-Output，多输入多输出)+OFDM(Orthogonal Frequency Division Multiplexing，正交频分复用)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。
在标准化发展过程中MIMO技术的维度不断扩展。在LTE Rel-8中，最多可以支持4层的MIMO传输。在Rel-9中增强MU-MIMO(Multi-User MIMO，多用户多输入多输出)技术，TM(Transmission Mode，传输模式)-8的MU-MIMO传输中最多可以支持4个下行数据层。在Rel-10中将SU-MIMO(Single-User MIMO，单用户多输入多输出)的传输能力扩展至最多8个数据层。
产业界正在进一步地将MIMO技术向着三维化和大规模化的方向推进。3GPP已经完成了3D信道建模的研究项目，并且正在开展eFD(Enhanced Full Dimension，增强的全维度)-MIMO和NR(New Radio，新空口)MIMO的研究和标准化工作。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。
Massive(大规模的)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。因此各大研究组织均将massive MIMO技术视为下一代移动通信系统中最有潜力的物理层技术之一。
在massive MIMO技术中如果采用全数字阵列，可以实现最大化的空间分辨率以及最优MU-MIMO性能，但是这种结构需要大量的AD(模数转换)/DA(数模转换)器件以及大量完整的射频-基带处理通道，无论是设备成本还是基带处理复杂度都将是巨大的负担。
为了避免上述的实现成本与设备复杂度，数模混合波束赋形技术应运而生，即在传统的数字域波束赋形基础上，在靠近天线系统的前端，在射频信号上增加一级波束赋形。模拟赋形能够通过较为简单的方式，使发送信号与信道实现较为粗略的匹配。模拟赋形后形成的等效信道的维度小于实际的天线数量，因此其后所需的AD/DA转换器件、数字通道数以及相应的基带处理复杂度都可以大为降低。模拟赋形部分残余的干扰可以在数字域再进行一次处理，从而保证MU-MIMO传输的质量。相对于全数字赋形而言，数模混合波束赋形是性能与复杂度的一种折中方案，在高频段大带宽或天线数量很大的系统中具有较高的实用前景。
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。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。
模拟波束赋形是全带宽发射的，并且每个高频天线阵列的面板上每个极化方向阵元仅能以时分复用的方式发送模拟波束。模拟波束的赋形权值是通过调整射频前端移相器等设备的参数来实现。
在学术界和工业界，通常是使用轮询的方式进行模拟波束赋形向量的训练，即每个天线面板每个极化方向的阵元以时分复用方式依次在约定时间发送训练信号(即候选的赋形向量)，终端经过测量后反馈波束报告，供网络侧在下一次传输业务时采用该训练信号来实现模拟波束发射。波束报告的内容通常包括最优的若干个发射波束标识以及测量出的每个发射波束的接收功率。
在做beam measurement(波束测量)时，网络会配置RS resource set(参考信号资源集合)，其中包括至少一个参考信号资源，例如SSB(Synchronization Signal Block,同步信号块)resource或CSI-RS(Channel State Information-Reference Signal，信道状态信息参考信号)resource。UE(User Equipment，用户设备)测量每个RS resource的L1-RSRP(L1-Reference Signal Received Power,层一参考信号接收功率)，并将最优的至少一个测量结果上报给网络，上报内容包括SSBRI(Synchronization Signal Block resource index，同步信号块资源索引)或CRI(Channel State Information-Reference Signal resource index，信道状态信息参考信号资源索引)、及L1-RSRP。该报告内容反映了至少一个最优的波束及其质量，供网络确定用来向UE发送信道或信号的波束。
在NR Rel-15中，每个载波最大的channel bandwidth(信道带宽)是400MHz。但是考虑到UE能力，UE支持的最大带宽可以小于400MHz，且UE可以工作在多个小的BWP上。每个带宽部分对应于一个Numerology(数值配置)，bandwidth(带宽)，frequency location(频率位置)。对于FDD(Frequency Division Duplexing，频分双工)系统或者paired spectrum(成 对频谱)，基站给UE配置至多四个下行BWP和至多四个上行BWP。对于TDD(Time Division Duplexing，时分双工)系统或者unpaired spectrum(非成对频谱)，基站给UE配至多四个DL(下行)/UL(上行)BWP pair(对)。每个DL/UL BWP pair中的DL BWP和UL BWP的中心载频是一样的。此外，每个UE会有一个default(默认)DL BWP，或者default DL/UL BWP pair。default DL BWP，或者default DL/UL BWP pair通常是一个相对小带宽的BWP，当UE长时间没有收到数据或者检测到PDCCH(Physical Downlink Control Channel，物理下行控制信道)，UE会通过一个timer(定时器)，从当前的active(激活)BWP切换到default DL BWP或者default DL/UL BWP pair，从而达到省电的效果。Active BWP切换是通过RRC(Radio Resource Control，无线资源控制)或DCI(Downlink Control Information，下行控制信息)或timer来实现，例如，在第一个CORESET(control-resource set,控制资源集)上的DCI指示UE切换到第二个CORESET，则在UE切换到第二个CORESET上后，该CORESET所在BWP即为active BWP。每个小区每个BWP上的CORESET最多为3个。
对于PDCCH的beam indication(波束指示)，网络使用RRC信令为每个CORESET配置K个TCI(Transmission Configuration Indication，传输配置指示)state(状态)，当K>1时，由MAC(media access control，媒体接入控制)CE(Control Element，控制元素)指示1个TCI state，当K＝1时，不需要额外的MAC CE命令。UE在监听CORESET时，对CORESET内全部search space(搜索空间)使用相同QCL(Quasi-colocation，准共址)信息，即相同的TCI state。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、SSB等)与UE-specific(特定的)PDCCH DMRS(De-modulation Reference Signal,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。
对于PDSCH(Physical Downlink Shared Channel，物理下行共享信道)的波束指示，网络通过RRC信令配置M个TCI state，再使用MAC CE命令激活2 N个TCI state，然后通过DCI的N-bit TCI字段(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。UE根据该TCI状态即可获知使用哪个接收波束来接收PDSCH。
对于PUCCH(Physical Uplink Control Channel，物理上行链路控制信道)的波束指示，网络使用RRC信令为每个PUCCH resource配置spatial relation information(空间关系信息)，当为PUCCH resource配置的spatial relation information包含多个entry(入口)时，使用MAC-CE指示其中一个entry的spatial relation information。当为PUCCH resource配置的spatial relation information只包含1个entry时，不需要额外的MAC CE命令。
对于PUSCH(Physical Uplink Shared Channel，物理上行共享控制信道)的波束指示，网络通过RRC信令配置PUSCH的相关信息。用于特定BWP的UE specific PUSCH的参数配置的IE(information element，信息元素)为PUSCH-Config，其中包括：数据加扰信息、预编码信息、DMRS信息、功控信息、跳频信息、资源分配信息、MCS(Modulation and Coding Scheme，调制与编码策略)信息、RBG(Resource Block Group，资源块组)信息等。用于cell specific PUSCH的参数配置的IE为PUSCH-ConfigCommon，其中包括：组跳频信息、资源分配信息等。此外，还会配置PUSCH的功控信息等。PUSCH的spatial relation信息是当PDCCH承载的DCI调度PUSCH时，DCI中的SRI field的每个SRI codepoint(码点)指示一个SRI，该SRI用于指示PUSCH的spatial relation(空间关系)信息。
另外，在上述描述中，波束也可以称为spatial filter(空间滤波器)，spatial domain transmission filter(空间域传输滤波器)等。波束信息可以称为TCI state信息、QCL信息、spatial relation信息等。
相关技术中，当网络侧在小区和/或BWP(bandwidth part，带宽部分)上配置了信道或参考信号时，通常会为信道或参考信号配置相应的波束信息，对于下行信道或参考信号会配置TCI(Transmission Configuration Indication，传输配置指示)state(状态)，其中的QCL(Quasi-colocation，准共址)信息包括：BWP-Id(标识)和reference signal(源参考信号)等；对于上行信道或参考信号会配置spatial relation(空间关系)信息，其中包括BWP-Id和 reference signal等。
相关技术存在以下问题：当reference signal与目标信道或参考信号属于不同小区和/或BWP时，如果目标信道或参考信号所在BWP为active(激活的)BWP，那么无法对位于其它BWP的reference signal进行测量并确定其波束信息，也就无法确定目标信道或参考信号的波束信息。
为了解决上述技术问题，本公开的实施例提供一种确定波束信息的方法及装置、通信设备，能够在网络侧设备没有为所有小区和/或带宽部分上的信道或信号配置波束信息时，确定这些信道或信号的波束信息，进而能够节省网络侧配置波束信息的信令开销。
本公开的实施例提供一种确定波束信息的方法，应用于用户设备，如图1所示，包括：
步骤101：根据目标通信资源的配置信息确定源参考信号在所述目标通信资源所在的小区和/或BWP的第一信息，所述源参考信号与所述目标通信资源关联且与所述目标通信资源位于不同的小区和/或BWP；
其中，目标通信资源可以为目标参考信号或目标信道。目标通信资源可以为网络侧设备为用户设备配置的通信资源，也可以为协议规定的通信资源。
源参考信号可以为SSB、CSI-RS或SRS。
步骤102：根据所述第一信息确定所述目标通信资源的波束信息。
如果网络侧设备为用户设备的目标信道或信号配置了波束信息，且源参考信号所在的小区和/或BWP与目标信道或信号所在的小区和/或BWP相同，则无需执行步骤102；如果网络侧设备为用户设备的目标信道或信号配置了波束信息，且源参考信号所在的小区和/或BWP与目标信道或信号所在的小区和/或BWP不同，则需要执行步骤102得到源参考信号在目标信道或信号所在的小区和/或BWP上的资源位置信息；如果网络侧设备未对用户设备的目标信道或信号配置波束信息，则选取一小区和/或BWP，该小区和/或BWP上的信道或信号配置了波束信息，对该小区和/或BWP上的信号或信道的源参考信号执行步骤102，得到源参考信号在目标信道或信号所在的小区和/或BWP上的资源位置信息，其中，可以仅为一个信道或信号配置波束信息，同一小区和/或BWP中、或其它小区和/或BWP中、或同一频带中、或同一预 设信道或信号组中、或同一用户的其他信道或信号均可以利用该信道或信号波束信息，这样可以节省网络配置波束信息的信令开销。
本实施例中，在源参考信号与网络侧设备分配的目标通信资源位于不同的小区和/或BWP时，根据网络侧设备分配的目标通信资源的配置信息确定源参考信号在目标通信资源所在的小区和/或BWP的第一信息，并根据第一信息确定目标通信资源的波束信息。这样对于没有配置波束信息的目标信道或信号，可以根据其它信道或信号的源参考信号，确定源参考信号在目标信道或信号的所在小区和/或BWP上的资源位置信息，能够在网络侧设备没有为所有小区和/或带宽部分上的信道或信号配置波束信息时，确定这些信道或信号的波束信息，从而可以节省网络配置波束信息的信令开销。

下面结合具体的实施例对本公开的技术方案进行进一步介绍：
实施例一
假设目标信道或信号为PUCCH，reference signal为CSI-RS。
(1)网络侧设备通过RRC信令为UE配置PUCCH，其中包括PUCCH所在的上行BWP ID；
其中，不是全部上行BWP都配置有PUCCH资源的spatial relation信息(即波束信息)，至少一个上行BWP上没有配置PUCCH的spatial relation信息。如：
PUCCH resource 1配置在BWP 1且配置有spatial relation，其reference signal为CSI-RS resource 1，CSI-RS resource 1所在BWP为BWP 1；
PUCCH resource 2配置在BWP 2且配置有spatial relation，其reference signal为CSI-RS resource 1，CSI-RS resource 1所在BWP为BWP 1；
PUCCH resource 3配置在BWP 3但未配置spatial relation。
(2)如果当前BWP(或active BWP，或PUCCH所在的BWP)上配置了PUCCH spatial relation信息
a、如上述PUCCH resource 1，其reference signal与PUCCH resource 1都在BWP 1；
1、在BWP1上，通过对CSI-RS resource 1的波束测量，UE得到CSI-RS resource 1的波束信息，即QCL信息。
2、由于CSI-RS resource 1是PUCCH resource 1的reference signal，所以可以确定PUCCH resource 1的spatial relation信息。
b、如上述PUCCH resource 2，其reference signal与PUCCH resource 2在不同BWP，即PUCCH resource 2在BWP2，其reference signal在BWP 1；
1、根据CSI-RS resource 1在BWP1中的位置信息、BWP2的信息等，确定CSI-RS resource 1在BWP2上的位置信息；
2、在BWP2上，通过对CSI-RS resource 1的波束测量，UE得到CSI-RS resource 1的波束信息，即QCL信息。
3、由于CSI-RS resource 1是PUCCH resource 2的reference signal，所以可以确定PUCCH resource 2的spatial relation信息。
(3)与(2)相反，如果没有配置PUCCH spatial relation信息
a、如上述PUCCH resource 3，在BWP3上未配置PUCCH resource 3 的spatial relation信息
1、选取PUCCH resource 1的reference signal，即CSI-RS resource 1,作为PUCCH resource 3的reference signal；
2、根据CSI-RS resource 1在BWP1中的位置信息、BWP3的信息等，确定CSI-RS resource 1在BWP3上的位置信息；
3、在BWP3上，通过对CSI-RS resource 1的波束测量，UE得到CSI-RS resource 1的波束信息，即QCL信息。
由于确定了CSI-RS resource 1是PUCCH resource 3的reference signal，所以可以确定PUCCH resource 3的spatial relation信息。
(4)对于配置了多个spatial relation信息的PUCCH resource，网络侧设备使用MAC CE命令，指示一个PUCCH spatial relation信息。
(5)UE利用网络指示的一个PUCCH spatial relation信息，确定PUCCH的发送波束。
实施例二
在实施例一的基础上，可将其中的PUCCH替换为其它信道或信号，如PDCCH。如果目标信道或信号为下行信道或信号，则将spatial relation信息替换为TCI state信息或QCL信息。
对于embedded BWPs(即重叠的两个BWP资源)，第一BWP包含在第二BWP中，对于reference signal在第一BWP，目标信道或信号在第二BWP，则不需再确定reference signal在这两个BWP上的资源位置信息；对于reference signal在第二BWP且不属于第一BWP，目标信道或信号在第一BWP，则需根据本公开的技术方案，确定reference signal在第一BWP上的资源位置信息。
实施例三
在源参考信号为CSI-RS时，可以根据以下方式确定源参考信号在目标信号或信道所在的小区和/或BWP的资源位置信息：
如果B小于所述目标通信资源所在的小区和/或BWP的资源起始位置N start，则所述源参考信号在所述目标通信资源所在的小区和/或BWP的资源起始位置C＝N start，否则C等于B；
如果A大于S+N start-C，则所述源参考信号在所述目标通信资源所在的小区和/或BWP的资源数量D＝S+N start-C，否则D＝A，其中，A为源参考信号的资源数量，B为源参考信号的资源起始位置，S为目标信号或信道所在的小区和/或BWP的资源数量。
具体地，在所述源参考信号为CSI-RS时，可以根据以下方式确定源参考信号在目标信号或信道所在的小区和/或BWP的资源位置信息：
如果

其中，nrofRBs为CSI-RS的资源数量(资源块RB数量)，
Figure PCTCN2020083501-appb-000009
为BWP的大小，即BWP所包含的资源数量(资源块RB数量)；
其中，
Figure PCTCN2020083501-appb-000010
在源参考信号为SRS时，可以根据以下方式确定源参考信号在目标信号或信道所在的小区和/或BWP的资源位置信息：
在目标信号或信道所在的小区和/或BWP的频域起始位置N start小于等于预设的频域偏移值时，源参考信号在目标信号或信道所在的小区和/或BWP的频域起始位置为公共资源中的子载波0，否则，源参考信号在目标信号或信道所在的小区和/或BWP的频域起始位置为目标信号或信道所在的小区和/或BWP中的最低子载波。
具体地，在所述源参考信号为SRS时，如果
Figure PCTCN2020083501-appb-000011
则所述SRS在所述目标通信资源所在的BWP中的频域起始位置(起始的子载波位置)为公共资源中的子载波0，否则为所述目标通信资源所在的BWP中的最低子载波，即BWP包含的子载波中频率最低的那个子载波。
