Description

一种指示UE发射端口数量的方法、UE及网络设备 技术领域
本发明涉及信息处理技术领域，尤其涉及一种指示UE发射端口数量的方法、用户设备(UE)、网络设备及计算机存储介质。
背景技术
当前，随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性，为此3GPP国际标准组织开始研发5G。在NR早期部署时，完整的NR覆盖很难获取，所以典型的网络覆盖是广域的LTE覆盖和NR的孤岛覆盖模式。而且大量的LTE部署在6GHz以下，可用于5G的6GHz以下频谱很少。所以NR必须研究6GHz以上的频谱应用，而高频段覆盖有限、信号衰落快。同时为了保护移动运营商前期在LTE投资，提出了LTE和NR之间tight interworking的工作模式。
用户设备，比如手机，在射频设计是按band设计的，但是由于在某些band组合下，UE能够使用的天线数目是变化的，即可能是1个或者2个。而若网络侧与UE侧的天线使用情况以及资源分配情况并未匹配时，可能会存在通信性能的问题。
发明内容

具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
实施例一、
本发明实施例提供了一种指示用户设备UE发射端口数量的方法，应用于UE，如图1所示，包括：
步骤101：若当前的频带组合为存在性能降低情况的频带组合，则判断当前的频点及带宽组合是否存在性能降低情况，得到判断结果；
步骤102：基于所述判断结果，确定指示网络侧所述UE使用第一数量或第二数量个发射端口；其中，所述第一数量小于第二数量。
这里，所述第二数量可以为UE所具备的全部发射端口(Tx)的数量，比如，通常会为2个；第一数量可以为小于第二数量的正整数，比如，可以为1个。
前述频带组合可以为：不同的系统的频带的组合，也就是说，一个组合中通常可以包括有至少两个频带，比如，频带组合中可以包括有一个LTE系统的频带、以及一个NR系统的频带；并且，不同的频带组合中包含的频带至少存在一个不同，即假设频带组合1中包括有LTE频带1+NR频带1，频带组合2中可以包括有LTE频带1+NR频带2，频带组合3中可以包括有LTE频带3+NR频带3。
当前频带组合是否存在性能降低情况可以为UE侧预设的，或者可以为UE侧在长期使用过程中总结得到的，本实施例中不进行限定。
另外，在存在性能降低情况的频带组合中，UE在某一个区域(比如某一个小区内)进行通信时，通常仅采用该小区对应的信道或频点进行通信，此时，频点及其对应的带宽中的通信情况并不存在性能降低的情况，那么就可以采用最多发射端口进行通信。
下面分别基于不同的示例对前述步骤进行详述：
示例1、
在执行步骤101之前，UE进入连接态后，向网络侧发送无线能力。
其中，所述无线能力包括：所述UE在至少一种频带组合下的性能降低指示信息；所述频带组合中包括有至少两个频带；所述性能降低指示信息用于表征在对应的频带组合下是否存在性能降低情况。
或者，所述无线能力包括：所述UE在至少一种频带组合下使用的发射端口的数量；所述频带组合中包括有至少两个频带。
有可能导致UE产生性能降低的情况，例如由IMD(互调)问题引起的性能降低。
也就是说，UE在双连接场景下，两个系统的频带组合可能会导致UE的性能下降，那么通过无线能力，向网络侧通知UE在EN-DC场景下每个频带(Band)组合下的性能降低指示；如果存在性能降低问题，则该指示为ture，默认使用1TX，否则不上报该指示。
或者，直接指示在某些频带组合下使用1Tx指示。
另外，前述将无线能力上报给网络侧之后，相应的，网络侧将所有能力信息转发给CN保存。当UE再次进入连接状态时，网络侧可以从CN侧直接获取UE无线能力信息，而不是通过UE上报。
假定UE已经将UE无线能力信息上报给网络侧并保存在CN。UE在小区中获取小区的频点和带宽信息获取。
另外，在UE获取到的关于EN-DC配置信息之后，获取EN-DC其他小区的频点和带宽信息。
在此基础上，网络可以咨询终端有关某个BC情况下的channel allocation的2Tx能力信息；即在执行步骤101之前，还可以包括当网络侧确定UE当前的频带组合为存在性能降低情况的频带组合时，并确定UE当前所在小区对应的频点及带宽，那么可以主动向UE发起询问，获取UE在频点及带宽组合下是否也存在性能降低情况；
相应的，UE在收到前述询问时，执行步骤101。
可以理解的是，收到网络侧的询问可以为一种实施方式，其实还可以存在其他实现方式，比如，可以由UE获知当前所在小区的频点及带宽，然后主动执行，若当前的频带组合为存在性能降低情况的频带组合，则判断当前的频点及带宽组合是否存在性能降低情况，得到判断结果。
进一步地，前述步骤102中，基于所述判断结果，确定指示网络侧所述UE使用第一数量或第二数量个发射端口，还包括：
若所述判断结果表征当前的频点及带宽组合不存在性能降低情况，则 指示所述网络侧所述UE使用第二数量个发射端口。
也就是说，如果当前配置的band组合存在性能降低问题，则UE进一步判断当前的频点和带宽组合是否还存在性能降低问题，如果不存在，则UE在RRC连接重配置完成消息中指示支持2TX。否则不进行指示。
通过前述描述，可以理解到UE一旦发生无线环境的变化，就会判断其当前所在的环境中的频带组合、以及频点及带宽组合是否存在性能降低情况。比如，当UE在前一个小区已经确定了采用的发射端口的数量，在UE移动过程中，如果EN-DC配置发生变化或者环境发生变化(例如靠近小区中心)，则UE判断当前配置的band组合是否存在性能降低问题，存在则UE进一步判断当前的频点和带宽组合是否还存在性能降低问题，不存在，则在响应消息中指示支持2Tx。
最后本示例还需要指出的是，当UE通过辅小区群SCG SRB向网络侧上报支持发射端口(Tx)的数量时，辅小区群的基站会将该数量发送至UE的主小区群所在的基站侧；即SN通过Xn转发该TX数目给MN。
示例2、
执行步骤101之前，还可以包括：接收网络侧发来的配置信息，其中，所述配置信息中包括有频带组合、和/或、频点及带宽组合；
基于所述配置信息，确定所述频带组合和/或所述频点及带宽组合，所支持第一数量个发射端口或支持第二数量个发射端口。
即首先网络下发可能的Band Combination或者Channel Allocation配置；也就是说，网络侧可发来当前自身管理的全部小区所对应的频带组合情况，以及频带及带宽组合的情况；
UE可以基于接收到的列表，通过Capability标识出哪些仅能支持第一数量1Tx，哪些肯定支持第二数量2Tx；此时，可以将标识出第一数量以及第二数量的反馈信息发送给网络侧。
进一步地，终端可以发送preference标识某些有问题的band也可以支持2Tx，使用的信令可以是UE辅助信息；
并且，如果环境发生变化(如UE移动)，终端可以发送preference标识某些有问题的band也可以支持2Tx，使用的信令可以是UE辅助信息。
与示例1相同的是，终端的preference标识可以是网络咨询终端是否能支持2Tx后发送的；当然也可以为UE自身检测到变化之后向网络侧发送。
示例3：
所述方法还包括：向网络侧发送硬件能力信息；其中，所述硬件能力信息表征所述UE是否能够支持第二数量的发射端口。硬件能力，即2Tx能力支持。
所述基于所述判断结果，确定指示网络侧所述UE使用第一数量或第二数量个发射端口，包括：
当所述硬件能力信息表征所述UE支持第二数量的发射端口时，
若所述判断结果表征当前的频点及带宽组合存在性能降低情况，则确定指示网络侧所述UE使用第一数量个发射端口；否则，不指示网络侧所述UE使用的发射端口的数量。
其中，上报的方式可以为UE通过动态RRC信令，如UE辅助信息上报在当前环境下是否能够支持2Tx，例如仅能支持1Tx；
如果UE上报，则网络按照1Tx去配置，或者调整资源分配；如果UE未上报，则网络按照2Tx配置。
示例4、
本示例基于示例1中向网络侧发送无线能力的场景之上，
所述方法还包括：
向网络侧发送无线能力之后，判断是否接收到网络侧发来的至少一个频点及带宽组合询问信息；
若接收到网络侧发来的至少一个频点及带宽组合询问信息，则向网络侧发送所述至少一个频点及带宽组合支持第一数量或第二数量个发射端口。
终端先汇报基于band组合的capability,网络在接到终端的汇报后，可以进一步指示终端是否需要在汇报基于某个或某些band组合,颗粒度是channel的capability。
可见，通过采用上述方案，就能够结合UE在频带组合、以及频点带宽组合的性能情况，确定向网络侧指示当前的环境下使用第一数量或第二数量的发射端口进行通信。如此，就能够使得网络侧获取到UE在当前所处环境下的性能，从而能够基于该通信性能确定为UE所要分配的资源，如此，保证了UE的通信性能。
实施例二、
本发明实施例提供了一种指示用户设备UE发射端口数量的方法，应用于网络设备，包括：若当前的频带组合为存在性能降低情况的频带组合，则获取UE发来的指示，通过所述指示确定所述UE使用第一数量或第二数量个发射端口；其中，所述第一数量小于第二数量。
这里，所述网络设备可以为管理UE的基站，当UE能够连接两个网络时，比如，连接主小区群、以及辅小区群时，可以为其中的一个基站；并且其中的主小区群以及辅小区群，可以分别为LTE小区以及NR小区。最优的实施例中，所述网络设备可以为主小区群(即LTE小区)中的基站。
所述第二数量可以为UE所具备的全部发射端口(Tx)的数量，比如，通常会为2个；第一数量可以为小于第二数量的正整数，比如，可以为1个。
前述频带组合可以为：不同的系统的频带的组合，也就是说，一个组合中通常可以包括有至少两个频带，比如，频带组合中可以包括有一个LTE 系统的频带、以及一个NR系统的频带；并且，不同的频带组合中包含的频带至少存在一个不同，即假设频带组合1中包括有LTE频带1+NR频带1，频带组合2中可以包括有LTE频带1+NR频带2，频带组合3中可以包括有LTE频带3+NR频带3。
当前频带组合是否存在性能降低情况可以为UE侧预设的，或者可以为UE侧在长期使用过程中总结得到的，本实施例中不进行限定。
另外，在存在性能降低情况的频带组合中，UE在某一个区域(比如某一个小区内)进行通信时，通常仅采用该小区对应的信道或频点进行通信，此时，频点及其对应的带宽中的通信情况并不存在性能降低的情况，那么就可以采用最多发射端口进行通信。
下面分别基于不同的示例对前述步骤进行详述：
示例1、
所述UE进入连接态后，判断核心网侧是否保存有所述UE对应的无线能力，若未保存，则向所述UE发送获取无线能力的请求信息。
其中，所述无线能力包括：所述UE在至少一种频带组合下的性能降低指示信息；所述频带组合中包括有至少两个频带；所述性能降低指示信息用于表征在对应的频带组合下是否存在性能降低情况。
或者，所述无线能力包括：所述UE在至少一种频带组合下使用的发射端口的数量；所述频带组合中包括有至少两个频带。
有可能导致UE产生性能降低的情况，例如由IMD(互调)问题引起的性能降低。
也就是说，UE在双连接场景下，两个系统的频带组合可能会导致UE的性能下降，那么通过无线能力，向网络侧通知UE在EN-DC场景下每个频带(Band)组合下的性能降低指示；如果存在性能降低问题，则该指示为ture，默认使用1TX，否则不上报该指示。
或者，直接指示在某些频带组合下使用1Tx指示。
另外，前述将无线能力上报给网络侧之后，相应的，网络侧将所有能力信息转发给CN保存。当UE再次进入连接状态时，网络侧可以从CN侧直接获取UE无线能力信息，而不是通过UE上报。
假定UE已经将UE无线能力信息上报给网络侧并保存在CN。UE在小区中获取小区的频点和带宽信息获取。
另外，在UE获取到的关于EN-DC配置信息之后，获取EN-DC其他小区的频点和带宽信息。
在此基础上，网络可以咨询终端有关某个BC情况下的channel allocation的2Tx能力信息；即当网络侧确定UE当前的频带组合为存在性能降低情况的频带组合时，并确定UE当前所在小区对应的频点及带宽，那么可以主动向UE发起询问，获取UE在频点及带宽组合下是否也存在性能降低情况。

进一步地，若接收到的指示表征所述UE发来的使用第二数量个发射端口，则确定所述UE对应的当前的频点及带宽组合不存在性能降低情况。
也就是说，如果当前配置的band组合存在性能降低问题，则UE进一步判断当前的频点和带宽组合是否还存在性能降低问题，如果不存在，则UE在RRC连接重配置完成消息中指示支持2TX。否则不进行指示。
通过前述描述，可以理解到UE一旦发生无线环境的变化，就会判断其当前所在的环境中的频带组合、以及频点及带宽组合是否存在性能降低情况。比如，当UE在前一个小区已经确定了采用的发射端口的数量，在UE 移动过程中，如果EN-DC配置发生变化或者环境发生变化(例如靠近小区中心)，则UE判断当前配置的band组合是否存在性能降低问题，存在则UE进一步判断当前的频点和带宽组合是否还存在性能降低问题，不存在，则在响应消息中指示支持2Tx。
最后本示例还需要指出的是，当UE通过辅小区群向网络侧发送指示时，通过Xn获取所述辅小区群发来的所述指示。具体的：当UE通过辅小区群SCG SRB向网络侧上报支持发射端口(Tx)的数量时，辅小区群的基站会将该数量发送至UE的主小区群所在的基站侧；即SN通过Xn转发该TX数目给MN。
示例2、
向UE发送配置信息，其中，所述配置信息中包括有频带组合、和/或、频点及带宽组合；
相应的，所述UE接收网络侧发来的配置信息，其中，所述配置信息中包括有频带组合、和/或、频点及带宽组合；基于所述配置信息，确定所述频带组合和/或所述频点及带宽组合，所支持第一数量个发射端口或支持第二数量个发射端口。
即首先网络下发可能的Band Combination或者Channel Allocation配置；也就是说，网络侧可发来当前自身管理的全部小区所对应的频带组合情况，以及频带及带宽组合的情况；
UE可以基于接收到的列表，通过Capability标识出哪些仅能支持第一数量1Tx，哪些肯定支持第二数量2Tx；此时，可以将标识出第一数量以及第二数量的反馈信息发送给网络侧。
进一步地，终端可以发送preference标识某些有问题的band也可以支持2Tx，使用的信令可以是UE辅助信息；
并且，如果环境发生变化(如UE移动)，终端可以发送preference标 识某些有问题的band也可以支持2Tx，使用的信令可以是UE辅助信息。
与示例1相同的是，终端的preference标识可以是网络咨询终端是否能支持2Tx后发送的；当然也可以为UE自身检测到变化之后向网络侧发送。
示例3：
接收UE发来的硬件能力信息；其中，所述硬件能力信息表征所述UE是否能够支持第二数量的发射端口；硬件能力，即2Tx能力支持。
当接收到UE发来的指示表征使用第一数量个发射端口时，基于所述第一数量个发射端口进行资源配置；
当未接收到UE发来的指示表征使用第一数量个发射端口时，基于所述第二数量个发射端口进行资源配置。
其中，上报的方式可以为UE通过动态RRC信令，如UE辅助信息上报在当前环境下是否能够支持2Tx，例如仅能支持1Tx；
如果UE上报，则网络按照1Tx去配置，或者调整资源分配；如果UE未上报，则网络按照2Tx配置。
示例4、
本示例基于示例1中向网络侧发送无线能力的场景之上，
接收到UE发来的无线能力之后，向所述UE发送至少一个频点及带宽组合询问信息；
接收所述UE发来的针对所述至少一个频点及带宽组合支持第一数量或第二数量个发射端口。
也就是说，终端先汇报基于band组合的capability,网络在接到终端的汇报后，可以进一步指示终端是否需要在汇报基于某个或某些band组合,颗粒度是channel的capability。
可见，通过采用上述方案，就能够结合UE在频带组合、以及频点带宽组合的性能情况，确定向网络侧指示当前的环境下使用第一数量或第二数 量的发射端口进行通信。如此，就能够使得网络侧获取到UE在当前所处环境下的性能，从而能够基于该通信性能确定为UE所要分配的资源，如此，保证了UE的通信性能。
实施例三、
本发明实施例提供了一种UE，如图2所示，包括：
第一处理单元21，若当前的频带组合为存在性能降低情况的频带组合，则判断当前的频点及带宽组合是否存在性能降低情况，得到判断结果；基于所述判断结果，确定指示网络侧所述UE使用第一数量或第二数量个发射端口；其中，所述第一数量小于第二数量；
第一通信单元22，向网络侧发送所述指示。
这里，所述第二数量可以为UE所具备的全部发射端口(Tx)的数量，比如，通常会为2个；第一数量可以为小于第二数量的正整数，比如，可以为1个。
前述频带组合可以为：不同的系统的频带的组合，也就是说，一个组合中通常可以包括有至少两个频带，比如，频带组合中可以包括有一个LTE系统的频带、以及一个NR系统的频带；并且，不同的频带组合中包含的频带至少存在一个不同，即假设频带组合1中包括有LTE频带1+NR频带1，频带组合2中可以包括有LTE频带1+NR频带2，频带组合3中可以包括有LTE频带3+NR频带3。
当前频带组合是否存在性能降低情况可以为UE侧预设的，或者可以为UE侧在长期使用过程中总结得到的，本实施例中不进行限定。
另外，在存在性能降低情况的频带组合中，UE在某一个区域(比如某一个小区内)进行通信时，通常仅采用该小区对应的信道或频点进行通信，此时，频点及其对应的带宽中的通信情况并不存在性能降低的情况，那么就可以采用最多发射端口进行通信。
下面分别基于不同的示例对前述步骤进行详述：
示例1、
第一通信单元22，UE进入连接态后，向网络侧发送无线能力。
其中，所述无线能力包括：所述UE在至少一种频带组合下的性能降低指示信息；所述频带组合中包括有至少两个频带；所述性能降低指示信息用于表征在对应的频带组合下是否存在性能降低情况。
或者，所述无线能力包括：所述UE在至少一种频带组合下使用的发射端口的数量；所述频带组合中包括有至少两个频带。
有可能导致UE产生性能降低的情况，例如由IMD(互调)问题引起的性能降低。
也就是说，UE在双连接场景下，两个系统的频带组合可能会导致UE的性能下降，那么通过无线能力，向网络侧通知UE在EN-DC场景下每个频带(Band)组合下的性能降低指示；如果存在性能降低问题，则该指示为ture，默认使用1TX，否则不上报该指示。
或者，直接指示在某些频带组合下使用1Tx指示。
另外，前述将无线能力上报给网络侧之后，相应的，网络侧将所有能力信息转发给CN保存。当UE再次进入连接状态时，网络侧可以从CN侧直接获取UE无线能力信息，而不是通过UE上报。
假定UE已经将UE无线能力信息上报给网络侧并保存在CN。UE在小区中获取小区的频点和带宽信息获取。
另外，在UE获取到的关于EN-DC配置信息之后，获取EN-DC其他小区的频点和带宽信息。
在此基础上，网络可以咨询终端有关某个BC情况下的channel allocation的2Tx能力信息；当网络侧确定UE当前的频带组合为存在性能降低情况的频带组合时，并确定UE当前所在小区对应的频点及带宽，那么 可以主动向UE发起询问，获取UE在频点及带宽组合下是否也存在性能降低情况。
可以理解的是，收到网络侧的询问可以为一种实施方式，其实还可以存在其他实现方式，比如，可以由UE获知当前所在小区的频点及带宽，然后主动执行，若当前的频带组合为存在性能降低情况的频带组合，则判断当前的频点及带宽组合是否存在性能降低情况，得到判断结果。
进一步地，第一处理单元21，若所述判断结果表征当前的频点及带宽组合不存在性能降低情况，则指示所述网络侧所述UE使用第二数量个发射端口。
也就是说，如果当前配置的band组合存在性能降低问题，则UE进一步判断当前的频点和带宽组合是否还存在性能降低问题，如果不存在，则UE在RRC连接重配置完成消息中指示支持2TX。否则不进行指示。

所述第一处理单元21，当所述硬件能力信息表征所述UE支持第二数量的发射端口时，
若所述判断结果表征当前的频点及带宽组合存在性能降低情况，则确定指示网络侧所述UE使用第一数量个发射端口；否则，不指示网络侧所述UE使用的发射端口的数量。
其中，上报的方式可以为UE通过动态RRC信令，如UE辅助信息上 报在当前环境下是否能够支持2Tx，例如仅能支持1Tx；
如果UE上报，则网络按照1Tx去配置，或者调整资源分配；如果UE未上报，则网络按照2Tx配置。
示例4、
本示例基于示例1中向网络侧发送无线能力的场景之上，
