Abstract

Description

一种天线轮发的方法及装置
本申请要求在2020年3月25日提交中国国家知识产权局、申请号为202010217166.4的中国专利申请的优先权，发明名称为『一种天线轮发的方法及装置』的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及天线技术领域，尤其涉及天线轮发技术。
背景技术
在长期演进技术(Long-Term Evolution，LTE)以及新空口(New Radio，NR)系统中，在时分双工(Time-Division Duplexing，TDD)频段引入了探测参考信号(Sounding Reference Signal，SRS)天线轮发技术，即所谓的SRS天线轮发。即用户设备(User Equipment，UE)在不同天线发送SRS信号，基站基于TDD系统的上下行信道互易性原理，得到UE不同天线的信道估计结果，从而算出最适合UE下行接受的权值，进行波速赋形。
由于目前5G的电子设备都支持4天线从基站接收数据，而针对不同的组网模式，在NSA模式下，只支持单天线向基站发送数据，SA模式下可以支持两根天线向基站发送数据。因为当前的电子设备尺寸有限，天线数目也有限，但是又需要支持多模同时工作，比如NSA场景，LTE和NR同时工作，又比如双卡场景，4天线中有2根天线被LTE占用，会和NR的SRS轮发造成天线间的冲突。
发明内容
本申请提供一种实施例，根据用户设备所处的组网模式及场景不同，而进行天线动态轮发的方法。
第一方面，本申请提供一种天线轮发方法，包括：用户设备UE确定所处的组网模式，UE根据所述确定的所处组网模式，确定当前所处场景。UE根据当前所述场景确定天线轮发顺序，其中，所述天线轮发顺序包括第一轮发顺序和第二轮发顺序，UE根据所述天线轮发顺序进行天线轮发。
通过实施上述技术方案，可以有效解决在各个场景下，天线冲突问题，提升天线吞吐效率。
结合第一方面，在第一种可能的实施方式中，UE根据当前所述场景确定天线轮发顺序包括：所处组网模式为第一组网模式时，UE确定第一天线组合和第二天线组合，其中，所述第一天线组合包括所述UE副卡未占用的天线，第二天线组合包括UE副卡占用的天线，UE根据所述第一天线组合确定所述轮发顺序为第一轮发顺序。
结合第一方面的第一种可能的实施方式，在第二种可能的实施方式中，UE包括N根天线，其中N为正整数，其中副卡占用的天线为M根，其中，M为大于等于1小于等于M的正整数；则第一天线组包括N-M根天线，第二天线组包括M根天线。
结合第一方面的第二种可能的实施方式，在第三种可能的实施方式中，第一天线组为0根天线时，UE停止天线轮发。

具体实施方式
本申请以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非 旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在也包括复数表达形式，除非其上下文中明确地有相反指示。还应当理解，本申请中使用的术语“和/或”是指并包含一个或多个所列出项目的任何或所有可能组合。
本申请提供一种SRS动态轮发方法，为了更好的理解本申请，下面对本申请中涉及到的一些关键概念进行解释，其中本申请的UE可以理解为电子设备，本申请对此不进行限定。
SRS，即当基站想要获取下行信息只需要把UE发送的上行探测信号进行测量就可以直接使用了，这种用于上行信道探测的参考信号就是SRS。
SRS天线轮发技术，即充分利用5G电子设备的多根天线轮流上报信道信息(即SRS天线轮发)，能够让基站获取的信息更全面，进行更精准的数据传输。如图1(a)所示，为在NSA场景下的1T1R，即只固定在一个天线上向基站反馈SRS信息，即不支持SRS轮发。如图1(b)所示，为电子设备在1T4R场景下,即电子设备在4个天线上轮流发射SRS信号，一次选择1个天线发射；支持NSA的电子设备常采用这种模式。如图1(c)所示，电子设备在2T4R场景下，即电子设备的4个天线上轮流发射SRS信号，一次选择2个天线发射；支持SA的电子设备常采用这种模式。还存在有1T2R等，以此类推，本申请不做任何限定。
图2给出一种UE确定SRS动态轮发方法的流程图，其中假设UE包括N根天线，其中N为正整数，具体如下：
S201 UE确定当前所处组网模式，若处于第一组网模式则跳转到步骤S302,若处于第二组网模式，则跳转到步骤S305。
S202 当UE处于第一组网模式时，即NSA模式时，UE确定当前所处场景。UE根据所处场景，确定副卡需要占用的天线为M根，这M分根天线视为第二天线组，其中，M为大于等于1，小于等于N的正整数。而UE中副卡未占用的N-M根天线为第一天线组。
S203 UE根据第一天线组选择第一轮发顺序。
S204 UE根据第一轮发顺序进行SRS天线轮发。
S205 当UE处于第二组网模式时，即SA模式时，UE确定当前所处场景。UE根据所处场景，UE一次性选择Q根天线进行发射。将天线平均分Q组，每组中的天线间对应进行天线轮发。当前确定副卡需要占用的天线为M根，这M分根天线视为第四天线组，其中，M为大于等于1，小于等于N的正整数。而UE中副卡未占用的N-M根天线为第三天线组。
S206 UE据第三天线组选择第二轮发顺序。即若相同天线组中的天线均属于第三天线组，则天线进行正常轮发；若相同天线组中存在属于第四天线组的天线，则在属于第三天线组中的天线进行天线轮发；若同一天线组中的天线都属于第四天线组，则该组天线不进行天线轮发。
S207 UE据第二轮发顺序进行SRS天线轮发。
图3示出了本申请的一种SRS动态轮发方法的实施例。UE仍然上报最大的 SRS轮发能力，当副卡或者其他模式占用一根天线时。例如双卡场景下，此时副卡仅有接收，此时NR只有三根天线可以进行SRS轮发。图3(a)所示，为在NSA场景下，即1T4R。具体的，假设此时天线3为副卡发送，即此时天线3为副卡占用，即天线3为第二天线组。而天线0、天线1和天线2均为未被副卡占用，则此时天线0、天线1和天线2为第一天线组。具体如表1-1可知。
表1-1
Figure PCTCN2021082228-appb-000001
具体的，原有的轮发顺序为从天线0依次到天线3，而此时当天线3被占用时，再进行SRS轮发，则会产生冲突。而基于本申请提出的方法，UE确定第一天线组和第二天线组，第一天线组为副卡未占用的天线，第二天线组为副卡占用的天线，则UE根据第一天线组确定第一轮发顺序。如表1-1，UE根据第一天线组，将轮发顺序修改为0->1->2->y或者0->1->2->x(其中，x表示不发，y表示0,1,2之间任意一个)，即第一轮发顺序。UE采用第一轮发顺序进行SRS轮发
具体的，当副卡占用的天线为2时，第一天线组则为天线0、天线1和天线3，而此时第二天线组为天线2,。此时，UE根据第一天线组，将第一轮发顺序修改为0->1->3->y或者0->1->3->x，其中，x表示不发，y表示0,1,3之间任意一个。
当UE处于第二组网模式时，即UE处于SA，如图3(b)所示，即2T4R。具体的，假设此时天线3为副卡发送，即此时天线3为副卡占用，即天线3为第二天线组。而天线0、天线1和天线2均为未被副卡占用，则此时天线0、天线1和天线2为第一天线组。具体如表1-2可知。
表1-2
Figure PCTCN2021082228-appb-000002
具体的，原有的轮发顺序为从天线0到天线2，天线1到天线3，即0,1->2,3。而当天线3被占用时，再进行SRS轮发，则会产生冲突。而基于本申请提出的方法，UE确定第三天线组和第四天线组，第三天线组为副卡未占用的天线，第四天线组为副卡占用的天线，则UE根据第三天线组确定第二轮发顺序。如表1-2，UE根据第三天线组，将轮发顺序修改为0，1->2，y或者0,1->2,x(其中，x表示不发，y表示1)，即第二轮发顺序。UE采用第二轮发顺序进行SRS轮发。
具体的，当副卡占用的天线为2时，第一天线组则为天线0、天线1和天线3，而此时第四天线组为天线2,。此时，UE根据第三天线组，将第二轮发顺序修改为0，1->y，3或者0,1->x,3，(其中，x表示不发，y表示0)。
通过上述方法保证UE仍然可以上报最大轮发能力，在其他模或者卡空闲态或者不工作时，仍然可以做最大轮发，达到下行峰值吞吐。在副卡占用一根天线时，仍然可以做到3根天线的动态SRS轮发。UE的下行吞吐体验提升，且不增加硬件成本，不影响其他模或者卡工作。以上实施例仅为本申请的一种具体情况，本申请对此不做任何限定。
基于上述实施方式，图4给出了另一种SRS动态轮发方法的实施例。当副卡或者其他模只占用两根天线。比如双卡双通场景，副卡此时既有接收又有发送，接收和发射用不同天线，R有两根天线可以SRS轮发。如图4(a)所示，当UE处于第一组网模式下时，即在NSA场景下，即1T4R。具体的，假设此时天线3为副卡发送，天线2为副卡接收，即此时天线2和天线3为副卡占用，即天线2和天线3为第二天线组。而天线0、天线1和均为未被副卡占用，则此时天线0、天线1为第一天线组。UE根据第一天线组，确定SRS轮发顺序，具体如表1-3可知。
表1-3
Figure PCTCN2021082228-appb-000003
具体的，当副卡占用的天线为2和天线3时，第一天线组则为天线0、天线1，而此时第二天线组为天线2和天线3。此时，UE根据第一天线组，将第一轮发顺序修改为0->1->(x或y)->(x或y)(其中，x表示不发，y表示0,1之间任意一个)。即UE仅在天线0和天线1之间进行轮发。
当UE处于第二组网模式时，即UE处于SA，如图4(b)所示，即2T4R。具体的，假设此时天线3为副卡发送，天线2为副卡接收，即此时天线2和天线3为副卡占用，即天线2和天线3为第三天线组。而天线0、天线1和均为未被副卡占用，则此时天线0、天线1为第四天线组。UE根据第三天线组，确定SRS轮发顺序，具体如表1-4可知。
表1-4
Figure PCTCN2021082228-appb-000004
具体的，原有的轮发顺序为从天线0到天线2，天线1到天线3，即0,1->2,3。 而当天线3被占用时，再进行SRS轮发，则会产生冲突。而基于本申请提出的方法，UE确定第三天线组和第四天线组，第三天线组为副卡未占用的天线，第四天线组为副卡占用的天线，则UE根据第三天线组确定第二轮发顺序。如表1-3，UE根据第三天线组，将轮发顺序修改为0,x->1,x(其中，x表示不发)，即第二轮发顺序。UE采用第二轮发顺序进行SRS轮发。即，UE天线0和天线1进行SRS轮发，天线2和天线3不进行轮发。
进一步的，当天线2为副卡接收，天线3位副卡发送时，此时UE确定第四天线组包括天线1和天线3，此时第三天线组包括天线0和天线1。那么UE根据第三天线组确定新的轮发顺序为0,x->2,x，即天线0和天线2之间进行轮发，而天线1和3之间不轮发。
通过上述方法保证UE仍然可以上报最大轮发能力，在其他模或者卡空闲态或者不工作时，仍然可以做最大轮发，达到下行峰值吞吐。在副卡抢占2根天线时，仍然可以做到2根天线的动态SRS轮发。
基于上述实施方式，图5给出了另一种SRS动态轮发方法的实施例。当副卡或者其他模只占用三根天线。比如双卡双通场景，特殊硬件方案设计等，副卡此时占用一根发送天线，两根接收天线，接收和发射用不同天线，NR只有一根天线可以SRS轮发。如图5(a)所示，当UE处于第一组网模式下时，即在NSA场景下，即1T4R。具体的，假设此时天线3为副卡发送，天线1和天线2为副卡接收，即此时天线1、天线2和天线3为副卡占用，即天线1、天线2和天线3为第二天线组。而天线0未被副卡占用，则此时天线0为第一天线组。UE根据第一天线组，确定SRS轮发顺序，具体如表1-5可知。
表1-5

具体的，当副卡占用的天线为天线1、天线2和天线3时，第一天线组则为天线0，而此时第二天线组为天线1、天线2和天线3。此时，UE根据第一天线组，将第一轮发顺序修改为0->(0或x)->(0或x)->(0或x)其中，x表示不发。即UE仅在天线0进行轮发。
当UE处于第二组网模式时，即UE处于SA，如图5(b)所示，即2T4R。具体的，假设此时天线3为副卡发送，天线1和天线2为副卡接收，即此时天线1、天线2和天线3为副卡占用，即天线1、天线2和天线3为第四天线组。而天线0未被副卡占用，则此时天线0为第三天线组。UE根据第三天线组，确定SRS轮发顺序，具体如表1-6可知。
表1-6

具体的，原有的轮发顺序为从天线0到天线2，天线1到天线3，即0,1->2,3。而当天线3被占用时，再进行SRS轮发，则会产生冲突。而基于本申请提出的方法，UE确定第三天线组和第四天线组，第三天线组为副卡未占用的天线，第四天线组为副卡占用的天线，则UE根据第三天线组确定第二轮发顺序。如表1-6，UE根据第三天线组，将轮发顺序修改为0,x->0,x(其中，x表示不发)，即第二轮发顺序。UE采用第二轮发顺序进行SRS轮发。即，UE天线0进行SRS轮发，天线1、天线2和天线3不进行轮发。
基于上述实施方式，图6给出了另一种SRS动态轮发方法的实施例。当副卡或者其他模占用四根天线。比如双卡时分复用场景，副卡此时占用所有天线，主卡暂时不工作，NR没有天线发送。如图6(a)所示，当UE处于第一组网模式下时，即在NSA场景下，即1T4R。具体的，假设此时天线3为副卡发送，天线0，天线1和天线2为副卡接收，即此时天线0，天线1、天线2和天线3为副卡占用，即天线0，天线1、天线2和天线3为第二天线组,则第一天线组没有天线。UE根据第一天线组，确定SRS轮发顺序，具体如表1-7可知。

当UE处于第二组网模式时，即UE处于SA，如图6(b)所示，即2T4R。具体的，假设此时天线3为副卡发送，天线0，天线1和天线2为副卡接收，即此时天线0，天线1、天线2和天线3为副卡占用，即天线0，天线1、天线2和天线3为第四天线组,则第三天线组没有天线。UE根据第三天线组，确定SRS轮发顺序，具体如表1-8可知。

通过实施上述实施例，UE仍然上报最大轮发能力，在其他模或者卡空闲态或者不工作时，仍然可以做最大轮发，达到下行峰值吞吐。在副卡抢占四根天线时，则天线不进行轮发。
