Therefore, when the UE side establishes the uplink and downlink beam links with the 5G New Radio (NR) base station (gNB), the diversity gain can be increased. If blocking occurs during transmission, the UE can avoid communication interruption caused by beam blocking through panel switching, and better achieve uplink and downlink reception and transmission. Therefore, in order to enhance multi-beam operation in UL transmission, UE terminals configured with multiple panels should be supported.

The beam misalignment at the UE side affects the system performance. In addition, the base station also needs to know the panel status information on the UE side (whether it is activated, etc.) and the number of configured panels. Otherwise, the base station may schedule the UE with the beam corresponding to the deactivated panel, resulting in waste of network resources and throughput. reduce. Therefore, the panel status information of the UE and the panel switching event should be reported to the base station in time.

Description

一种用户设备的天线面板切换方法及通信设备 【技术领域】
本申请涉及无线通信领域，尤其涉及一种用户设备的天线面板切换方法、通信设备及可读存储介质。
【背景技术】
在多输入多输出(Multiple-Input Multiple-Output,MIMO)通信系统中，上下行波束指示增强的目标主要是降低时延和开销。在多波束传输系统中，用户设备(User equipment，UE)可以配备有多个天线面板(panel)，其中每个天线面板可以包含多个天线单元。如图1所示。
每个面板可以放置UE端的不同位置。因此UE端与5G新空口(NR)基站(gNB)建立上下行波束链路时，可以增加分集增益。若在传输过程中发生阻塞时，UE可以通过面板切换避免因为波束阻塞造成的通信中断，更好地实现上下行接收和传输。因此，在为了增强UL传输中的多波束操作，应支持配置有多个面板的UE终端。虽然通过使用UE端的多个面板来增强上行传输能获得较大的传输增益，但是给定时隙内，也并不是始终需要同时激活所有的面板，并且多个天线面板同时处于激活状态时十分耗电，即使在某个时刻内，并不是所有激活的面板都用于上行传输。如果在给定时间内，只激活一个UE面板进行上行传输，这种机制需要每隔一段时间对UE的所有面板进行激活并测量，这是因为用于传输的UE面板可能会发生故障而中断上行传输，例如传输过程中有障碍物阻塞，UE发送移动、旋转等。因此，需要动态更新/检测上行传输面板以保持最好的传输性能，这是需要对UE进行面板激活/去激活(Panel activation/deactivation)机制，快速选择上行链路传输的最佳传输面板，同时也能节省发送功率。此外，上行传输受到最大允许排放量(Maximum Permissible Emission，MPE)的限制，UE需要进面板切换。简单地说，最大功率衰减(Maximum Power Reduction，MPR)是为了满足MPE需求而引入的。然而，在具有多面板的UE中，当分配给面板的功率受到MPR的影响时，最初选择的面板可能并非为上行链路传输的最优的选择。因此，需要通过面板激活/去激活的快速选择合适的面板以提供更好的传输。因此对UE进行面板激活/去激活也是解决MPE相关问题的一种解决方案。
在Rel-15中，天线组(Antenna group)激活/去激活机制不能很好地支持任何 使UE或基站能够有效地激活/停用任何天线组的方案。缺乏UE和基站之间在天线组激活/去激活方面的协调机制。
在Rel-16中，确定了三种类型的多面板用户(Multi-panel UE，MPUE),即:
MPUE-假设1：在一个UE上实现多个面板，一次只能激活一个面板，面板切换/激活延迟为[X]ms；
MPUE-假设2：在一个UE上实现多个面板，可以一次激活多个面板，并且可以使用一个或多个面板进行传输；
MPUE-假设3：在一个UE上实现多个面板，一次可以激活多个面板，但只能使用一个面板进行传输。
在Rel-16中就MPUE-假设3的多面板用户机制达成协议。UE通过面板激活/去激活机制，选择合适的上行面板。由于面板激活/去激活也可能对基站发送或接收产生影响，因此考虑两类主要的解决方案来进行面板选择，即：基站发起(基站-driven)和UE发起(UE-driven)的面板激活/去激活。在基站发起的面板选择机制中，基站周期性地唤醒面板进行波束或CSI测量，以选择最佳的传输面板。或者当UE检测需要进行上行面板切换时，向基站发送请求，此时UE测量面板传输质量并上报给基站，基站根据上报的信息指示UE进行面板选择；UE发起的面板激活/去激活机制是当UE发生位置移动、选择或者发生MPE问题等需要进行面板选择的事件时，UE自己选择新的面板而不需要基站的信令指示，该机制下，UE可以快速且独立地选择用于传输的面板/波束。
面板选择支持标准的透明方式，如果UE发生面板切换事件后，基站对于面板切换是未知的，这时基站继续使用与面板切换前相同的上行接收波束接收上行信道/信号，这就导致基站端和UE端的波束错位，影响系统性能。此外，基站还需要知道UE端的面板状态信息(是否被激活等)，以及所配置的面板数量，否则，基站可能会用已经去激活的面板所对应的波束调度UE，造成网络资源浪费和吞吐量降低。因此，UE的面板状态信息，面板切换事件应及时上报基站。在Rel-16中，已经达成协议使用标识符(Identifier,ID)来指示面板特定上行传输,为UE面板定义一个新的ID,即“panel ID”,显式的panel ID也有利于在UE和基站之间对齐面板激活/去激活信息，实现基站控制UE的面板激活/去激活，实现基站和UE端的对齐。同样，在Rel-16中，对于基于上行参考信号UL-RS的波束管理，基站为UE配置上行探测参考信号(Sounding reference signal,SRS)资源，UE将SRS资源与UL panels相关联，这对基站是透明的。选择的SRS资源通过 SpatialRelationInfo指示给UE，隐式实现面板特定上行传输。
在Rel-15/16中，上下行波束指示分别通过无线资源控制(Radio resource control,RRC)配置的传输配置指示(Transmission configuration indication,TCI)状态和高层参数SpatialrelationInfo实现。上下行波束单独指示需要基站配置上下行两个信令,这样会导致延时和信令开销。上行波束管理是基于上行参考信号SRS资源，基站至少配置一个用于波束管理的SRS资源集，通常，不同的SRS资源集与不同的天线面板相关联。不同SRS资源集中可以被同时传输，同一SRS资源集中的SRS资源仅仅通过时分复用(TDM)方式传输的。因此，SRS资源集选择可以应用于面板特定的波束选择。当UE进行面板切换机制后，基站也会切换上行接收波束，并可能会重新调度下行传输。因此上下行波束指示单独配置需要基站配置上下行两个信令,这样会导致延时和信令开销。
在Rel-17中，提出了用于上下行统一波束指示框架(Unified framework)的模型。不同于Rel-15/16需要不同的信令分别配置上下行参考信号机制，上下行统一波束指示设计中，上行参考信号和下行参考信号都配置在相同的TCI状态中，UE面板切换的机制需要据此重新设计，另外，在基于上下行统一波束指示框架下，仍存在基站和UE的错位问题。
【发明内容】
为解决上述问题，本申请提供一种用户设备的天线面板切换方法,所述方法执行于用户设备端，包括：
接收基站发送的TCI状态，至少两个面板共用一个所述TCI状态；

本申请还提供一种用户设备的天线面板切换方法，所述方法执行于用户设备端，包括：
待检测到面板切换事件时，根据预置的第一关系表，在与切换后的目标面 板所对应的时隙中发送所述目标面板对应的SRS至基站，所述第一关系表至少包括所述目标面板的索引与所述时隙的索引之间的映射关系；
接收所述基站重新配置的TCI状态并根据所述TCI状态调整所述目标面板的上下行传输。
本申请还提供一种用户设备的天线面板切换方法，所述方法执行于基站端，包括：

协同所述用户设备对所述目标面板的传输信道进行测量，根据测量结果重新配置TCI状态并将所述TCI状态发送至所述用户设备，以使所述用户设备调整所述目标面板的上下行传输。
本申请的有益效果在于，当用户设备检测到需要进行面板切换时，可以直接将当前传输面板切换至与所述传输面板共用一个TCI状态的候选面板，并只需向基站上报一个切换事件，基站在收到请求后调整自身的上行接收波束和下行传输波束，基站无需重新对所有面板进行测量以及重新配置TCI状态，减小了原有技术中面板切换所耗时长。
另外，本申请同时还解决了面板切换过程中基站和UE产生错位的问题。

可选的，所述第一关系表由基站RRC进行配置。
可选的，所述第一关系表由系统信息SI承载并发送至所述用户设备。
可选的，所述重新配置的TCI状态由DCI信息承载。
方案一
多个UE面板配置相同的TCI状态，UE使用相同面板进行下行接收和上行传输。
此方案中，用于多个UE面板的传输波束都是配置在相同的TCI状态中。TCI状态中配置有下行参考信号CSI-RS和/或上行参考信号SRS，其中每一个参考信号和UE面板的上下行传输波束相关。
示例性的，UE配置有N个天线面板，例如，当N＝4时，所配置面板分别标记为panel1～panel 4，其中，每个UE面板上配置多个波束，而且都包括上行波束和下行波束。基站及UE对所有UE面板及其波束进行测量以找到每个UE面板的最佳上下行波束及相应的面板质量。面板质量由面板质量参数体现，面板质量参数可以包括面板的信噪比(SINR)以及参考信号接收功率(RSRP)等等。具体的，对于下行波束测量，基站向UE发到每一个波束所对应的CSI-RS,UE进行测量。对于上行波束测量，基站收到来自UE的上行参考信号SRS后进 行测量。
本方案中，两个UE面板共用一个公共(common)TCI状态,如图7所示，Panel1当前用于上下行传输的面板，当发生需要进行面板选择/切换的事件时，上行传输由面板Panel1切换到Panel2,并使用前述所得到的最佳上下行波束进行传输，且Panel1和Panel2的上下行波束配置在一个公共的TCI状态中。
在此之前在对上下行波束进行测量时，根据预置的准则选择出两个的UE面板，利用其中性能最优的UE面板作为传输面板，其性能的优劣可参照上文中所提及的面板质量参数，另一个次优的作为传输面板的候选面板,传输面板和候选面板的下行接收波束和上行传输波束配置在相同的TCI状态中。
选择两个面板的准则为:UE和基站分别对激活面板上的上下行波束测量，如果最优的分上下行波束来自同一面板，则该面板为传输面板，此时选择次优上行波束和/或下行波束的所对应面板作为候选面板；如果最优上下行波束来自不同面板，则这上行波束对应的面板为传输面板，下行波束对应的面板为候选面板。也可以只以上行传输波束为基准，基站对来自UE的SRS信号进行测量之后,发送SRI指示UE并得到质量最好的两个上行波束，同时UE也对下行波束进行测量。然后分别选择质量最好的两个上行波束所对应的两个下行波束的CSI及面板索引上报给基站，得到多个传输面板和候选面板索引对。此外，也可以测量面板质量，如果通过测量面板的信噪比(SINR),参考信号接收功率(RSRP)等，选择质量最好的两个面板分别作为传输面板和候选面板，并将测量得到两个面板配置的波束的CSI信息上报基站。基站利用RRC配置TCI状态,并指示面板进行上下行传输。
在现有技术中，当UE检测到需要进行面板切换的MPE事件或者收到省电机制驱动等切换事件时，这意味着当前上行传输面板不再适合用于上行传输,需要切换到一个新的面板进行上行传输，在选择新的面板即目标面板之前，UE需要根据发生的事件向基站发出目标面板切换请求，基站重新对所有面板进行测量后选择目标面板并进行配置，最后重新指示上下行波束。如果UE在检测到切换事件之后自动进行面板切换，可能会导致基站和UE之间波束错位，从而影响通信性能。为了实现基站和UE之间的波束对齐，UE在进行面板选择之前，需要将选择的面板通过上行参考信号发送给基站，基站通过测量进行面板选择并配置后重新指示上下行传输。以上现有方案都存在一定时延。而在本实施例方案中将传输面板和候选面板所对应的上下行传输波束都配置在相同的TCI状态 中，如图10所示，当UE检测到需要进行上行面板切换时，可以选择先行切换到候选面板，UE只需向基站上报面板切换事件，通知基站面板发生切换，基站随之调整自身的上行接收波束和下行传输波束，不需要通过RRC重新配置TCI。
方案二
多个UE面板配置相同的TCI状态，UE使用不同面板进行下行接收和上行传输。
本方案中，UE在不同面板上分别执行下行接收和上行传输，即执行一次上下行传输至少需要使用两个面板。该方案中，基站或UE对所配置面板及其相应的上下行波束进行测量，以选择最佳上行/下行波束及相应的面板。对于具有多面板UE的通信系统，当发生需要进行面板选择/切换的事件时，即当前的传输面板不适合继续用于上行传输，此时需要进行重新上行面板选择/切换。
如果面板切换后，UE继续使用切换前的接收面板进行下行接收，此时用于下行接收的面板，用于上行的传输面板以及用于上行传输的候选面板共用一个TCI状态，如图8所示。下行接收面板为两个上行传输面板提供下行公共波束(common beam)。基站对来自UE的SRS测量之后,发送SRI指示UE并得到质量最好的两个上行波束。同时UE对来自基站的CSI-RS进行测量，并将测量的CSI信息上报基站，基站根据对上下行波束的测量为两个波束配置下行公共波束。
另外如果面板切换后，UE使用与切换前不同的接收面板进行下行接收，此时考虑两个UE面板对(panel pair)共用一个TCI状态进而减少信令开销。在对上下行波束进行测量时，根据一定准则分别选择出两个用于下行接收和上行传输的面板，其中性能最优的下行接收面板和上行传输面板作为传输面板对，另外两个次优下行接收面板和上行传输面板为候选面板对,传输面板对和候选面板对的下行接收波束和上行传输波束相同的TCI状态中。UE和基站分别对所配置面板上的上下行波束进行测量，基站对来自UE的SRS测量之后,获得面板信息，发送SRI指示UE并得到质量最好的两个上行波束，同时UE也对下行波束进行测量。然后UE选择质量最好的两个下行波束并将相应的CSI信息上报给基站。选择质量最好的上行波束和下行波束所对应的两个面板作为传输面板对，另外两个面板作为候选面板对。如图9所示，假如Panel1和Panel2是通过测量选择得到的两个上行波束所对应的面板,Panel4和Panel3分别为测量得到的两个下行两个波束所对应的面板，其中Panel1和Panel 4分别为下行和上行最优波束对应 的面板。
另外，方案二的面板切换流程与方案一相同，可参见图10。
方案三
不同UE面板配置不同的TCI状态，UE使用相同面板进行下行接收和上行传输。
本方案中UE配置N个天线面板，例如，当N＝4时，分别标记为panel1～panel4，每个UE面板上配置多个波束，而且都包括上行波束和下行波束。该方案中，UE通过相同面板进行上下行输出，当UE检测到MPE事件或者其它需要进行上行面板切换的事件时，为了使基站和UE端的上下行传输波束对齐，基站需要知道目标面板的信息。由于不同的面板配置不同的TCI状态，基站在知道目标面板的信息后还需要对其进行测量并重新配置后指示上下行传输。如表1所示，基站预先定义slot＝{slot 1,slot 2,......,slot N},并通过将面板索引与slot之间建立映射关系，将面板与slot进行关联，生成如表1所示的第一关系表。第一关系表可以在UE确定要接入某个小区时基站所发送的系统信息SI承载。当基站或者UE检测到需要进行面板切换的事件时,UE在某给定的时隙给基站发送上行参考信号SRS，例如，对于UE发起(UE-Driven)的面板选择,所切换到的目标面板是panel 1，则在是slot 1发送面板panel 1所对应的SRS给基站，基站通过接收到SRS的时隙就可以知道UE上行切换的目标面板是panel 1并进行测量，然后重新进行TCI配置，避免了因UE自行切换上行传输面板造成和基站端错位的问题。

方案四
不同UE面板配置不同的TCI状态，UE使用不同面板进行下行接收和上行传输。
本方案中，UE至少使用两个面板用于上下行传输，基站和UE分别对用于 下行接收和上行传输的面板进行测量以选择最佳上行和下行波束及相应的面板。对于具有多面板UE的通信系统，当发生需要进行面板选择/切换的事件时，即当前的传输面板不适合继续用于上行传输，这需要进行重新上行面板选择/切换。由于不同的面板配置不同的TCI状态，基站在知道目标面板的信息后还需要对其进行测量并重新配置后进行上下行传输。假设所配置的N个面板中，K个面板用于上行传输，L个面板用于下行接收,为了方便叙述，分别称为下行面板和上行面板。如表2所示，定义slot＝{slot 1,slot 2,......,slot K×L},并通过将面板上下行面板索引与slot之间映射关系。UE检测到需要进行面板切换的事件时,UE在某给定的时隙给基站发送上行参考信号SRS。
示例性的，当前UE正利用索引组为1的面板进行上下行传输，即上行panel 1和下行panel 1，当UE检测到需要进行面板切换的事件,切换到目标面板是panel 2。如果面板选择/切换后，UE继续使用切换前的接收面板进行下行接收，即下行面板1进行下行接收，则在slot L+1给基站发送上行参考信号SRS，基站通过接收到SRS信号的时隙就可以知道UE上行切换的目标面板panel 2并对目标面板测量并配置TCI状态。如果执行面板选择/切换后，UE使用与切换前不同的接收面板进行下行接收，则分别从slot L+2到slot 2×L分别向基站发送上行参考信号SRS,基站通过接收到SRS信号的时隙就可以知道UE切换的目标面板，对目标面板和下行接收面板进行测量并重新配置TCI状态。

表2
如图11所示，不同面板配置不同TCI状态情况下，如果UE在检测到切换事件之后自动进行面板切换，为了实现基站和UE之间的波束对齐，UE在进行目标面板选择之前，需要通过一定的方式告知基站所切换的目标面板。如果面板切换前后都是用相同的目标面板进行上下行传输，则通过表1中的映射关系，在目标面板对应的时隙发送上行参考信号给基站；如果面板切换前后使用不同的目标面板进行上下行传输，则通过表2中的映射方式，在给定的时隙发送相应的参考信号给基站。基站通过接收到SRS信号的时隙就可以知道UE切换的目标面板，对目标面板和下行接收面板进行测量并重新配置TCI状态。
