- the communication process is roughly as follows: the transmitting end such as the base station gNB uses a large-scale antenna array to receive In the direction where the terminal is located, a high-frequency beam with a frequency above 6 GHz is sent; the receiving terminal uses the millimeter wave antenna module to receive the above-mentioned beam, and establishes a communication connection with the transmitting terminal to send and receive information through the above-mentioned high-frequency beam.

Description
本公开涉及通信技术领域,尤其涉及一种传输信息的方法、装置、用户设备及基站。
5G NR(New Radio)开辟了许多新的频率用于传输,高频频谱的采用是5G NR的一个特点,其中以频点在6GHz以上的毫米波(mmwave)的应用最为典型。
在5G NR***的毫米波应用中,基站和用户设备(User Equipment,UE)之间利用波束赋形(beamforming)技术传输信息,通信过程大致如下:发射端如基站gNB利用大规模天线阵列对接收端所在方向,发送频点在6GHz以上的高频波束;接收端利用毫米波天线模组接收到上述波束后,与发射端建立通信连接,从而通过上述高频波束收发信息。
为了使用波束赋形技术,基站和UE可以使用波束扫描(Beam Sweeping)方式,来检测使用哪个波束进行发射才能满足在某个方向需要的最大发射功率EIRP和接收覆盖Spherical Coverage要求。
在5G毫米波中,目前确定的频段都是TDD(Time Division Duplexing,时分双工)频段,由于TDD频段都具有上下行互异性,即由于上行和下行都在一个频段中进行,所以信道条件类似,也就是说下行最优的波束beam,上行也应是最优,所以5G毫米波推荐UE实现波束对应(Beam Correspondence)能力。即UE下行接收用哪个波束,上行发射就使用相同序列的波束,从而避免UE再采用波束扫描方式确定上行波束,有效缩短beam的控制时间。
然而,若UE因高速移动等因素导致不同时刻基站与UE天线模组之间的相对位置发生了改变,采用上述波束对应方式确定的波束对可能无法实现最佳传输效果,进而影响传输性能。

这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
在本公开使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解,尽管在本公开可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本公开范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
本公开涉及的执行主体包括:移动通信网络如4G LTE(Long Term Evolution,长期演进)、LTE-NR interworking(互操作)、5G NR、6G等***中的基站和用户设备(User Equipment,UE),其中,基站可以是设置有大规模天线阵列的基站、子基站等。用户设备可以是用户终端、用户节点、移动终端或平板电脑等。在具体实现过程 中,基站和用户设备各自独立,同时又相互联系,共同实现本公开提供的技术方案。
本公开的应用场景为:UE和基站利用高频波束在第一预设工作模式下传输信息时,已根据BC(beam correspondence,波束对应)技术,确定第一预设工作模式下的最佳匹配波束对信息。该最佳匹配波束对信息,表示第一预设工作模式下UE发射的预设序列上行波束与基站发射的预设序列下行波束配合、承载基站与UE之间的信息传输时,可以获得最佳传输性能。本公开中,将第一预设工作模式下确定的最佳匹配波束对可以称为初始匹配波束对。其中,上行波束是指由UE向基站发射的高频波束;下行波束是指基站向UE发射的波束。
在某一时刻,UE和基站需要切换至第二预设工作模式,在第二预设工作模式下,若UE仍沿用第一预设工作模式下确定最佳匹配波束对的方式确定目标匹配波束对,无法获得期望的传输性能。
参见图1-1和图1-2根据一示例性实施例示出的一种传输信息的场景示意图,假设UE1在第一预设工作模式下利用预设波束扫描周期,比如,每5ms进行一次波束扫描,即可准确确定第一预设工作模式下所需的最佳匹配波束对,如图1-1所示,可以表示为:(beam 2,beam c),其中,beam 2代表基站发射的波束序列;beam c代表UE发射的波束序列。
在一示例性应用场景中,上述第一预设工作模式可以对应预设类型的UE,比如M型号的UE1,以图1-2所示的预设高铁沿线的专用基站为参照物、低速移动时的工作模式,本公开中可以称之为低速移动模式。其中,上述低速移动可以是速度不超过预设阈值,比如80公里/小时,也可以包括UE相对于预设铁路沿线基站静止的情况。
但当UE1进入第二预设工作模式后,比如高速移动模式,由于UE1相对于基站的移动速度发生了较大变化,比如移动速度升高至365公里/小时,因速度加快了很多,若UE1仍沿用第一预设工作模式下的波束扫描方式,如每5ms进行一次波束扫描,确定的匹配波束对信息很有可能跟不上UE1相对于基站的移动速度变化,导致UE1与基站之间的传输性能下降。
在UE类型和基站信息保持不变的情况下,UE和基站由第一预设工作模式切换至第二预设工作模式后,新确定的最佳匹配波束对信息相对于初始匹配波束对信息呈规律性变化,比如,对于固定位置的基站如设置于某一高速铁路沿线的预设基站A,当预设类型的UE相对于基站A的移动速度由V1变化为V2后,采用一定的波束偏移策略,如沿预设方向偏移预设数量的波束,对初始匹配波束对进行调整,即可获得第二预设工作模式下的最佳匹配波束对信息,即V2状态下的目标匹配波束对信息。其 中,UE类型相同,可以理解为该类型UE中天线模组的配置信息相同,上述天线模组的配置信息可以包括:天线模组的设置位置、发射功率配置等信息。
基于上述发现,本公开提出了一种传输信息的方法,其思想在于:当预设类型的UE即将或者已经由第一预设工作模式切换至第二预设工作模式时,利用预先确定的、适应于该工作模式变化的波束偏差配置信息,对初始匹配波束对进行调整,确定适用于第二预设工作模式的最佳匹配波束对,从而确保UE和基站在第二预设工作模式下的信息传输性能。
基于此,本申请提供了一种传输信息的方法,参见图2根据一示例性实施例示出的一种传输信息的方法流程图,所述方法可以包括以下步骤:
在步骤11中,获取波束偏差配置信息;
其中,所述波束偏差配置信息用于指示信息传输端在发生预设工作模式变化时,对第一预设工作模式下的初始匹配波束对进行调整,以确定第二预设工作模式下的最佳匹配波束对;上述信息传输端是指参与信息传输的UE和基站。
本申请中,上述预设工作模式变化是指信息传输端由第一预设工作模式切换至第二预设工作模式。其中,触使上述预设工作模式变化的因素可以包括:UE相对于基站的速度变化信息、位置变化信息等因素。
一般情况下,第二预设工作模式下的波束对变化速率大于第一预设工作模式下的波束对变化速率,其中,波束对变化速率是指单位时间内需要重新进行波束对应(Beam Correspondence)的次数。
上述初始匹配波束对是指信息传输端在第一预设工作模式下、按照预设波束扫描周期如5ms进行波束扫描后,确定的最佳匹配波束对。
本公开中,上述方法的执行主体可以是预设类型的UE,如M型号的UE1;也可以是设置于预设位置的基站,如设置于京津高铁沿线的基站,或者,设置于某城市预设地理区域内的基站等,本公开对此不作限制。
本公开中,上述波束偏差配置信息包括:用于表示波束偏移方向和波束偏差数量的目标波束偏差信息。
在本公开另一实施例中,上述波束偏差配置信息还可以包括:波束偏差适用时间信息,该波束偏差适用时间信息用于指示所述目标波束偏差信息的适用时间范围。
参见图3根据一示例性实施例示出的另一种传输信息的方法流程图,上述步骤11可以包括:
在步骤11-1中,确定所述目标波束偏差信息;
关于信息传输端如何确定上述目标波束偏差信息,本公开实施例中,信息传输端可以采用以下至少两种方式确定上述目标波束偏差信息:
第一种方式,根据额外波束扫描方式确定上述目标波束偏差信息;
本公开中,额外波束扫描是指在正常的周期性波束扫描之外,触发的波束扫描,该额外波束扫描用于确定适用于上述预设工作模式变化的目标波束偏差信息。
上述第一种方式的实现过程为:信息传输端首先通过额外波束扫描确定适应于当前应用场景的最佳匹配波束对;将上述最佳匹配波束对与按照正常的周期性波束扫描方式确定的初始匹配波束对进行比较,确定所述最佳匹配波束对相较于所述初始匹配波束对的偏差信息,从而获得所述目标波束偏差信息。
第二种方式,根据预设波束偏差预测模型预测所述目标波束偏差信息;
上述第二种方式的实现过程为:信息传输端比如UE可以获取到用于计算上述目标波束偏差信息的预设波束偏差预测模型,将目标应用场景对应的预设工作模式变化信息如UE相对于基站的速度、位置等变化信息作为输入信息,利用该模型可以自动计算出上述目标波束偏差信息,与上述第一种方式相比,无需触发波束扫描,可以快速确定目标波束偏差信息,还可以节约因额外波束扫描产生的信令开销以及资源占用。
以下将以信息传输端UE为例,分别对上述两种方式的实施过程进行详细介绍:
在上述第一种方式的具体实施过程中,信息传输端可以在检测到预设额外波束扫描触发条件时,触发UE进行额外波束扫描,以确定上述目标波束偏差信息。
针对上述步骤11-1的第一种方式,参见图4根据一示例性实施例示出的另一种传输信息的方法流程图,上述步骤11-1可以包括:
在步骤11-11中,获取额外扫描配置信息,所述额外扫描配置信息用于指示所述用户设备按照预设时间指示信息进行额外波束扫描;
仍以目标UE是UE1为例,UE1可以采用以下至少两种方式获取额外扫描配置信息:
***约定方式,根据UE1中预置的***约定信息获取所述额外扫描配置信息;
其中,上述预置***约定信息可以是不需要接收基站下发信令、内置在UE本端的配置信息,比如是,UE1在出厂设置时,固化在UE1的通信芯片中的***协议信息。或者是,UE1在接入基站覆盖的小区网络时,从基站下发的信息如***信息中,获取***约定的预置额外扫描配置信息。后序当UE1主动触发或被动触发额外波束扫描时,按照上述预置额外波束扫描配置信息进行额外波束扫描。
基站实时发送方式,UE接收基站实时下发的额外扫描配置信息;
上述基站实时发送方式的实施至少可以包括以下两种情况:
第一种情况,UE接收基站在第一预设触发条件下发送的额外扫描配置信息;
在本公开一实施例中,***可以约定:基站在检测到第一预设触发条件时,指示UE进行额外波束扫描以重新确定最佳匹配波束对。
其中,上述第一预设触发条件可以是以下任一条件:
条件一,基站检测到当前工作模式下的信息传输性能低于预设传输性能阈值时;
例如,基站确定目标UE当前的信道质量指示(channel quality indication,CQI)信息低于预设CQI阈值时,向所述目标UE发送额外扫描配置信息。
本公开实施例中,基站可以根据目标UE如UE1向基站上报的以下至少一种信息,确定上述信道质量指示信息:下行参考信号的RSRP(Reference Singnal Received Power,参考信号接收功率)、RSRQ(Reference Singnal Received Quality,参考信号接收质量)、RSSI(Received Singnal Strengthen Indicator,接收信号强度指示)、用于量化表示信道质量的CQI等级等信息。
条件二,UE当前接入的基站具备预设业务需求
示例性的,UE在移动过程中,由第一地理区域移动至第二地理区域时,覆盖第二地理区域的第二基站相对于覆盖第一地理区域的第一基站,执行的通信标准协议不同,例如,第一基站执行第一种通信标准协议,第二基站执行第二通信标准协议,由于第二种通信标准协议相对于第一通信标准协议增设了新的业务需求,因此,需要信息传输端确定更精确的匹配波束对信息,进而要求接入第二基站的目标UE在上述预设波束扫描周期的基础上进行额外波束扫描。
基于此,第二基站在检测到目标UE接入其覆盖的小区后,会主动向目标UE发送额外扫描配置信息,以指示目标UE进行额外波束扫描,从而获得更加精确的匹配波束对信息。
其中,上述示例性中,基站标识、通信协议类型、地理区域之间的对应关系可以如表一所示:

基站标识 | 地理区域 | 通信协议类型 |
第一基站 | 第一地理区域 | 第一种通信标准协议 |
第二基站 | 第二地理区域 | 第二种通信标准协议 |
第二种情况,UE在检测到第二预设触发条件时,请求基站下发所述额外扫描配置信息;
参见图5根据一示例性实施例示出的另一种传输信息的方法流程图,上述步骤11-11可以包括:
在步骤101中,当检测到第二预设触发条件时,向所述基站发送额外扫描配置请求;
其中,所述额外扫描配置请求用于请求基站下发额外扫描配置信息。
仍如上示例,本公开实施例中,当UE1自身检测到第二预设触发条件时,可以主动请求基站发送额外扫描配置信息,即向基站发送所述额外扫描配置请求。
其中,上述第二预设触发条件可以包括以下任一条件:
条件A、被配置为上述第二预设工作模式时;
示例性的,若UE1检测到预设用户触发信息,该用户触发信息被配置为触发UE1进入第二预设工作模式,比如,UE1被用户手动设置为高速移动模式;则UE1向基站发送上述额外扫描配置请求。
条件B、当前预设参数信息指示所述用户设备进入所述第二预设工作模式时;
在本公开一实施例中,UE1内置的传感器如速度传感器、加速度传感器等感测到的当前预设参数信息,例如速度信息,指示UE1当前进入第二预设工作模式如上述高速移动模式时,也可以主动向基站发送上述额外扫描配置请求。
本公开中,UE1可以通过上层信令或物理层信令将上述额外扫描配置请求发送给基站,其中,上层信令可以是RRC(Radio Resource Control,无线资源控制)信令、MAC(Medium Access Control,媒介访问控制)CE(Control Element,控制单元)信令等。
在步骤102中,接收所述基站响应于所述额外扫描配置请求后下发的所述额外扫描配置信息。
相应的,基站接收到上述额外扫描配置请求后,可以为UE1实时配置额外扫描配置信息并发送给UE1,或者,将预先确定的额外扫描配置信息发送给UE1。
在步骤11-12中,基于所述额外扫描配置信息进行所述额外波束扫描,获得额外扫描结果;
本公开中,上述额外扫描配置信息用于告知UE如何进行额外波束扫描,以进一步精确确定第二预设工作模式下的最佳匹配波束对。
在本公开中,上述额外扫描配置信息可以包括:额外扫描触发时间信息,用于 指示UE何时启动额外波束扫描。
情况一,上述额外扫描触发时间信息可以是周期性额外扫描指示信息;
在本公开一实施例中,所述周期性额外扫描指示信息可以包括:额外扫描时间窗口、额外扫描周期时长;
其中,上述额外扫描时间窗口用于指示UE在什么时间范围内进行额外波束扫描。在一实施例中,上述额外扫描时间窗口可以是具体的时间范围信息,如T1~T2,其中,T1表示第一次额外波束扫描的起始时刻,T2表示最后一次额外波束扫描的结束时刻。在另一实施例中,上述额外扫描时间窗口也可以表示为:扫描起始时间、预设扫描次数或预设持续时长如10分钟,本公开对其具体表现形式不作限定。
上述额外扫描周期时长表示相邻两次额外波束扫描之间的间隔时长。本公开实施例中,上述额外扫描周期时长小于上述预设波束扫描周期的时长。其中,该预设波束扫描周期时长是指第一预设工作模式下、用于确定初始匹配波束对信息的波束扫描周期时长,例如,每间隔5ms进行一次波束扫描以确定最佳匹配波束对;也是指上述正常周期性波束扫描使用的扫描周期间隔时长。相应的,上述额外扫描周期时长可以是4ms、3ms、2ms、1ms等时长。
上述步骤11-12可以包括:在所述额外扫描时间窗口内,按照所述额外扫描周期时长进行周期性波束扫描,获得额外扫描结果;
示例性的,假设上述额外扫描时间窗口为T0,上述额外扫描周期时长为3ms;则UE1会启动一个计时器,在T0时间窗口内,每间隔3ms触发一次额外波束扫描,确定当前工作模式下的最佳匹配波束对信息。
本公开实施例中,UE可以利用周期性额外波束扫描的方式经过多次有规律的额外波束扫描,可以获得更加准确的匹配波束对信息,以便后序基于上述多个额外扫描结果获得更准确的目标波束偏差信息,提高目标波束偏差信息的准确性。
情况二,上述额外扫描触发时间信息为非周期性触发时间指示信息;
上述非周期性触发时间指示信息可以包括:至少一个额外扫描触发时间信息;上述额外扫描触发时间信息可以是基站根据实际业务需要实时确定的。
相应的,上述步骤11-12可以包括:按照每个所述额外扫描触发时间信息进行所述额外波束扫描,获得所述额外扫描结果。
本公开实施例中,基站可以根据实际业务需要灵活指示UE进行额外波束扫描,以根据实时获得的额外扫描结果确定适用于当前工作模式的最佳匹配波束对信息,进而获得目标波束偏差信息,提高确定目标波束偏差信息的灵活性。同时,还可以减少 UE执行额外波束扫描的功耗。
在步骤11-13中,对所述额外扫描结果进行处理以确定所述目标波束偏差信息;
本公开一实施例中,UE1获得上述额外扫描结果之后,可以将额外扫描结果即最新确定的最佳匹配波束对信息与初始匹配波束对信息进行比较,获得上述目标波束偏差信息。
以上述步骤11-12的情况一为例,并结合图1-1所示的应用场景进行示例性说明,假设UE1通过额外波束扫描方式,比如每3ms进行一次额外波束扫描,确定第二预设工作模式下的最佳匹配波束对为(beam2、beam b);而UE1按照第一预设工作模式下的预设波束扫描周期,比如每隔5ms进行一次波束扫描,确定的初始匹配波束对为(beam2、beam c);则UE1可以确定上述预设工作模式变化对应的目标波束偏差信息为:在UE侧按照预设波束编号顺序偏移一个波束,例如,在UE1侧向图1-1所示右侧偏移一个波束。
应当理解的是,上述示例仅以一种预设工作模式变化下UE侧需要波束偏移为例,说明目标波束偏差信息所指示的波束偏移方向及波束偏移量。本公开另一实施例中,在另一种预设工作模式变化下,UE和基站可能需要同时基于初始匹配波束对进行波束偏移,比如目标波束偏差信息分别指示UE和基站按照预设波束编号顺序方向偏移预设数量的波束,并且,目标波束偏差信息所指示的波束偏移方向及波束偏移量会因不同的工作模式变化而不同,本公开对此不作限定。
在本公开另一实施例中,UE1也可以将上述额外扫描结果上报给基站,由基站根据上述额外扫描结果与初始匹配波束对信息进行比较,获得所述预设工作模式变化对应的目标波束偏差信息,如上述结合图1-1说明的示例,该目标波束偏差信息可以为:在UE1侧向右偏移一个波束。同理,在另一种工作模式变换的情况下,上述目标波束偏差信息包括:分别指示基站和UE进行同步波束偏移的信息。
以上对UE采用额外波束扫描方式确定所述预设工作模式变化对应的目标波束偏差信息进行了详细描述。
关于UE实施上述步骤11-1的第二种方式,即根据预设波束偏差预测模型预测所述目标波束偏差信息;
本公开实施例中,信息传输端如UE可以根据预设波束偏差预测模型,来预测上述预设工作模式变化信息对应的目标波束偏差信息。
其中,上述预设波束偏差预测模型,可以是***基于波束偏差信息历史记录确定的数学模型或者人工神经网络模型。
参见图6根据一示例性实施例示出的另一种传输信息的方法流程图,所述步骤11-1可以包括:
在步骤11-14中,确定所述预设波束偏差预测模型;
本公开中,信息传输端如UE可以采用以下至少两种方式确定上述预设波束偏差预测模型:
方式一,根据基站标识和用户设备的类型信息等信息,获取对应的所述预设波束偏差预测模型;
参见图7根据一示例性实施例示出的另一种传输信息的方法流程图,所述步骤11-14可以包括:
在步骤1101中,确定当前应用场景的传输端信息,所述传输端信息可以包括:基站信息和用户设备的设备类型;
其中,上述基站信息可以是基站的身份标识,如上述京津铁路沿线的基站标识。用户设备的设备类型如上述智能手机UE1的型号M,相同设备类型的用户设备具有相同的天线模组配置。
在步骤1102中,根据所述传输端信息从预设存储位置获取所述传输端信息对应的波束偏差预测模型,获得所述预设波束偏差预测模型。
本公开实施例适用于UE中未存储上述预设波束偏差预测模型的情况,或者,UE中存储的波束偏差预测模型未及时更新的情况,如最近一次更新时间距离当前时刻已超过预设时长阈值比如30天,云端服务器中可以存储针对相同基站群、同一设备类型的UE对应的的预设波束偏差预测模型。其中,上述相同基站群可以是设置于某一固定线路的多个基站,比如上述京津铁路沿线的系列基站。
上述预设波束偏差预测模型可以由信息传输端在多种预设工作模式变化下分别测得的波束偏差数据训练而成,上述波束偏差数据是指在UE经过上述路线沿途的基站时、针对不同的工作模式变化通过额外波束扫描方式确定的波束偏差信息。
在后续该模型的应用阶段,假设一用户携带相同类型的UE首次经过该路线,比如一用户首次随身携带M型号的智能手机搭乘预设车次高铁从A火车站驶往B火车站时,则该智能手机可以直接从云端或基站侧的预设存储位置获取适用于该M型号UE的预设波束偏差预测模型,当其经历类似的预设工作模式变化时,可以利用上述预设波束偏差预测模型自动预测目标波束偏差信息,从而快速确定适用于当前工作模式的目标匹配波束对信息,提高波束对调整效率。
方式二,将满足预设数量要求的波束偏差历史记录数据作为样本数据,训练所 述预设波束偏差预测模型。
参见图8根据一示例性实施例示出的另一种传输信息的方法流程图,所述步骤11-14可以包括:
在步骤1103中,获取不少于预设数量阈值的波束偏差历史记录数据;
其中,每条波束偏差历史记录数据可以包括:工作模式变化信息、波束偏差信息。上述波束偏差信息可以是UE在经历预设工作模式变化时,比如UE在一列高铁上,相对于铁路沿线基站、由低速移动模式切换至高速移动模式的过程中,采用上述额外波束扫描方式确定的目标波束偏差信息。
信息传输端在历史时刻每完成一次上述额外波束扫描后,可以将相应的工作模式变化信息以及获得的波束偏差信息作为一条历史记录数据存储至预设存储资源中,比如云端服务器、基站或UE中。当其存储有足够多的数据时,就可以将这些历史数据作为样本数据确定上述预设波束偏差预测模型。
在步骤1104中,将所述波束偏差历史记录数据作为样本数据进行模型训练,获得所述预设波束偏差预测模型。
以上述波束偏差历史记录数据存储于云端服务器为例,当云端服务器中存储了足够多的波束偏差历史记录数据后,云端服务器、基站或UE,可以利用这些数据作为样本数据进行数学建模或者采用机器学习方式训练人工神经网络模型,获得可以自动预测波束偏差信息的预设波束偏差预测模型。
在一示例性实施例中,假设用户小明携带M型号智能手机,乘坐了N次如50趟京津高铁,如始发站为北京南、终点站为天建站的动车;在京津高铁沿线各基站的位置是固定的,根据高铁的运行规律,动车由启动到逐渐加速至预设车速如365公里/小时的过程中,需要不断调整其匹配波束对信息以适应不断增加的移动速度。
假设上述匹配波束对调整过程均在1号基站覆盖范围内进行,则针对每一次的预设工作模式变化比如从80公里/小时~100公里/小时,均需要进行一次额外波束扫描以确定目标波束偏差信息,从而产生50条波束偏差历史记录数据。基于上述50条波束偏差历史记录数据可以拟合出一个数学模型,比如,利用线性拟合等方法得到上述速度变化信息与波束偏差对应的函数关系。
在步骤11-15中,将预设工作模式变化信息输入所述预设波束偏差预测模型,输出所述目标波束偏差信息。
其中,上述预设工作模式变化信息是使能信息传输端工作模式变化的因素集合,可以包括:UE相对于基站的速度变化信息、位置变化信息等。
在确定上述预设波束偏差预测模型之后,信息传输端比如基站或UE,只需将预设工作模式变化信息如速度变化信息输入至上述预设波束偏差预测模型中,即可自动计算适用于预设工作模式变化的目标波束偏差信息。
仍如上示例,当小明携带其M型号智能手机再次乘坐京津高铁时,比如第51次乘坐时,当动车由车速80公里/小时加速至100公里/小时的过程中,小明的智能手机可以直接根据上述线性函数和当前车速计算出目标波束偏差信息,从而利用该目标波束偏差信息对初始匹配波束对进行调整,获得适用于当前工作模式的目标匹配波束对。
在另一示例中,假设小山携带了相同类型的智能手机如上述M型号手机,首次乘坐京津高铁,则小山的智能手机可以首先从云端服务器获取上述函数关系,之后利用上述函数关系和当前车速计算所需波束偏差信息,后序可以利用该波束偏差信息对初始匹配波束对进行调整,获得适用于当前工作模式的目标匹配波束对信息。
本公开实施例中,信息传输端采用第二种方式确定目标波束偏差信息,因为无需采用传统的波束扫描方式即上述额外波束扫描方式重新确定最佳匹配波束对信息,有效节约了UE与基站之间传输额外波束扫描配置信息的信令开销,节约无线传输资源;另外,采用上述第二种方式还可以提高确定目标匹配波束对的效率,进而提高信息传输端对移动速度变化的适应能力,确保UE相对于基站高速移动时的信息传输性能。
此处需要说明的是,信息传输端还可以采用步骤11-1的第一种方式与第二种方式相结合的方式确定上述目标波束偏差信息。例如,当UE确定云端服务器中存储有适合其设备类型的预设波束偏差预测模型时,或者,确定有足够多的波束偏差历史记录数据时,可以采用上述模型预测方式获取上述目标波束偏差信息,从而减少***资源占用及信令开销。相应的,若UE或基站确定采用上述第二种方式确定的目标波束偏差信息不准确时,比如,输入预设波束偏差预测模型的工作模式变化信息与训练上述波束偏差预测模型时使用的工作模型变化信息相差较大,***反馈采用模型预测方式获得的目标匹配波束对无法达到期望传输性能,此时,基站可以指示UE切换至上述第一种方式即额外波束扫描方式确定上述目标波束偏差信息,以获得更加准确的波束偏差配置信息,使得信息传输端根据上述波束偏差配置信息确定的目标匹配波束对信息更准确,从而保障基站和UE之间的信息传输性能。
在步骤11-2中,根据所述目标波束偏差信息确定所述波束偏差配置信息。
UE按照上述额外波束扫描方式或模型预测方式确定目标波束偏差信息,该步 骤11-2的实施也可以包括两种情况:
情况一,UE可以根据自身确定的目标波束偏差信息确定上述波束偏差配置信息。之后,并将上述波束偏差配置信息上报基站,以使基站根据上述波束偏差信息适应性调整针对该UE的匹配波束,确保基站和所述UE之间顺利传输信息。该情况一中,UE可以按照自身确定的波束偏差配置信息调整上行波束,同时,基站根据UE确定的上述波束偏差配置信息同步调整对应的下行波束,从而重新确定用于承载UE与基站之间信息传输的目标匹配波束对。
情况二,UE将确定的目标波束偏差信息发送给基站,由基站根据所述目标波束偏差信息确定所述波束偏差配置信息。
参见图9根据一示例性实施例示出的另一种传输信息的方法流程图,上述步骤11-2可以包括:
在步骤11-21中,将所述目标波束偏差信息发送给所述基站,以使所述基站参考所述目标波束偏差信息生成所述波束偏差配置信息;
以5G NR***为例,在5G移动通信网络中,基站仍处于主导地位,即UE按照基站的指示进行信息传输,因此,UE可以将获取的目标波束偏差信息发送给基站,以使基站参考UE确定的目标波束偏差信息生成上述波束偏差配置信息。
其中,在基站参考UE确定的目标波束偏差信息生成上述波束偏差配置信息的过程中,基站可以视上述目标波束偏差信息为准确信息,进而生成波束偏差配置信息;基站也可以仅将上述UE确定的目标波束偏差信息作为参考信息,以自身确定的波束偏差信息为准,或者,利用上述UE确定的目标波束偏差信息修正基站自身确定的波束偏差信息,根据修正后的波束偏差信息生成上述波束偏差配置信息。
在步骤11-22中,接收所述基站发送的所述波束偏差配置信息。
在基站确定上述波束偏差配置信息之后,可以将上述波束偏差配置信息发送给UE,以使UE根据所述波束偏差配置信息对第一预设工作模式下的初始匹配波束对进行调整。
在步骤12中,当获知由所述第一预设工作模式切换至所述第二预设工作模式时,根据所述波束偏差配置信息对所述初始匹配波束对进行调整,获得目标匹配波束对;
在信息传输端如基站或UE获取到上述波束偏差配置信息之后,当上述预设工作模式变化发生时,可以根据上述波束偏差配置信息及时调整初始匹配波束对,获得适应上述工作模式变化的目标匹配波束对。
本公开中,根据执行主体的不同,上述步骤12的实施可以包括:
第一种情况,UE获知自身由所述第一预设工作模式切换至所述第二预设工作模式时,例如,UE根据内置速度传感器检测到的速度变换信息确定与基站之间需要由第一预设工作模式切换至第二预设工作模式时,告知基站根据上述波束偏差配置信息对初始匹配波束对中的下行波束如图1-1中的beam 2进行调整,UE自身也根据上述波束偏差配置信息同步对初始匹配波束对中的上行波束如图1-1中的beam c进行调整,获得适用于第二预设工作模式的目标匹配波束对。
第二种情况,基站获知UE由所述第一预设工作模式切换至所述第二预设工作模式时,例如,基站根据UE上报的速度信息确定与UE之间需要由第一预设工作模式切换至第二预设工作模式时,指示UE根据上述波束偏差配置信息对初始匹配波束对中的上行波束进行调整,基站自身也根据上述波束偏差配置信息同步对初始匹配波束对中的下行波束进行调整,获得适用于第二预设工作模式的目标匹配波束对。仍以图1-1所示的UE1为例,假设上述波束偏差配置信息指示UE1由第一预设工作模式切换至第二预设工作模式后,以图1-1所示向右偏移1个波束的方式调整波束对信息。
当UE1进入第二预设工作模式后,会按照上述波束偏差配置信息对初始匹配波束对即(beam 2、beam c)进行调整,确定(beam 2、beam b)为第二预设工作模式下的最佳匹配波束对。
如上所述,上述示例仅以一预设工作模式变化下、UE侧需要波束偏移为例,说明如何自动调整匹配波束对信息。在另一预设工作模式变化情况下,UE和基站可能需要同时基于初始匹配波束对进行波束对信息调整,比如,目标波束偏差信息分别指示UE和基站按照预设波束编号顺序方向偏移预设数量的波束,此种情况下,UE和基站按照上述波束偏差配置信息同步调整波束对信息。示例性的,如图10所示,当UE1相对于基站的移动速度由V1升高至V2时,表明UE和基站需要由第一预设工作模式切换至第二预设工作模式,则需要UE1和基站同步调整匹配波束对信息,各自按照预设波束编号顺序偏移一个波束,由上述第一预设工作模式下的初始匹配波束对(beam2、beam c)调整为第二预设工作模式下的目标匹配波束对(beam 3、beam b)。
在步骤13中,利用所述目标匹配波束对在所述第二预设工作模式下传输信息。
相应的,仍如上述图10示例,UE1在高速移动模式比如移动速度为V2的应用场景下,与基站之间即可通过目标匹配波束对(beam 3、beam b)进行信息传输。
在本公开另一实施例中,上述波束偏差配置信息除了包括上述目标波束偏差信息之外,还可以包括:波束偏差适用时间信息。示例性的,假设上述波束偏差适用时 间信息为1分钟,则该1分钟时长内,UE和基站均可以采用上述目标波束偏差信息不断调整波束对信息,仍如图10所示示例,在1分钟时长内,基站和UE可以将最佳匹配波束对依次调整为(beam 3、beam b)、(beam 4、beam a)等,按照上述目标波束偏差信息进行规律性调整。
可知,采用本公开提供的传输信息的方法,当UE和基站由第一预设工作模式切换至第二预设工作模式时,无需通过改变波束扫描策略实时确定最佳匹配波束对,即可以保持第一预设工作模式下的预设波速扫描周期,再根据预先确定的波束偏差配置信息即可预测第二预设工作模式下的最佳匹配波束对信息,有效解决了UE相对于基站高速移动场景中很难基于波束扫描方式实时确定最佳匹配波束对的技术难题,可以有效提高快速移动场景中用户设备与基站之间的信息传输性能,节约信息传输端的功耗。
以上以UE为执行主体对本公开提供的传输信息的方法进行了说明。
相应的,本公开还提供了一种传输信息的方法,可以应用于基站中。参见图11根据一示例性实施例示出的一种传输信息的方法流程图,所述方法可以包括:
在步骤21中,获取波束偏差配置信息,所述波束偏差配置信息用于指示信息传输端在发生预设工作模式变换时,对第一预设工作模式下的初始匹配波束对进行调整,以确定第二预设工作模式下的最佳匹配波束对;所述预设工作模式变化是指所述信息传输端由所述第一预设工作模式切换至所述第二预设工作模式;
参见图12根据一示例性实施例示出的一种传输信息的方法流程图,上述步骤21可以包括:
在步骤211中,确定目标波束偏差信息;
同上,所述目标波束偏差信息用于指示波束偏移方向和波束偏差数量。
对于基站来说,可以采用以下三种方式确定目标波束偏差信息:
方式一、接收UE发送的目标波束偏差信息,可参见上述UE确定目标波束偏差信息的实施例描述,此处不再赘述。
方式二、根据UE发送的额外扫描结果确定目标波束偏差信息;
参见图13根据一示例性实施例示出的另一种传输信息的方法流程图,上述步骤211可以包括:
在步骤2111中,接收用户设备发送的额外扫描结果;
其中,上述额外扫描结果是UE依据预设额外扫描配置信息进行额外波束扫描获得的最佳匹配波束对信息。
在步骤2112中,将所述额外扫描结果与所述初始匹配波束对进行比较,确定所述目标波束偏差信息。
该实施例与上述图4所示实施例对应,上述步骤2112与图4中步骤11-13的一种实施方式类似,只是执行主体不同,具体实施过程相互参见即可。
参见图14根据一示例性实施例示出的另一种传输信息的方法流程图,在上述步骤2111之前,所述步骤211还可以包括:
在步骤2110中,向所述用户设备发送所述预设额外扫描配置信息,所述额外扫描配置信息用于指示所述用户设备进行上述额外波束扫描以获得上述额外扫描结果。
本公开一实施例中,基站可以在UE接入其覆盖小区时就向UE下发上述预设额外扫描配置信息。
本公开另一实施例中,基站在以下任一条件下,实时向所述用户设备发送所述预设额外扫描配置信息:
所述基站检测到当前工作模式下的信息传输性能低于预设传输性能阈值时;或者,具备预设业务需求。可参见上述第一预设触发条件的描述,此处不再赘述。
方式三,与上述UE利用波束偏差预测模型自动确定目标波束偏差信息类似,本公开实施例中,基站同样也可以利用上述UE设备类型对应的波束偏差预测模型自动获得目标波束偏差信息。
综上,本公开中,基站也可以根据上述额外波束扫描方式确定目标波束偏差信息,和/或,根据预设波束偏差预测模型预测所述目标波束偏差信息。
在步骤212中,根据所述目标波束偏差信息确定所述波束偏差配置信息。
该步骤与上述步骤11-21对应,相互参见即可。
在步骤22中,将所述波束偏差配置信息发送给用户设备;
该步骤22属于与上述步骤11-22对应的步骤,此处不再详述。在本公开另一实施例中,该步骤并不是必须步骤,例如,在上述UE自身确定波束偏差配置信息的实施例中,不需要基站向UE发送波束偏差配置信息。
在步骤23中,当获知由所述第一预设工作模式切换至所述第二预设工作模式时,根据所述波束偏差配置信息对所述初始匹配波束对进行调整,获得目标匹配波束对;
本公开实施例中,该步骤23与上述步骤12类似,相互参见即可。
在步骤24中,根据所述目标匹配波束对在所述第二预设工作模式下传输信息。
基站在确定第二预设工作模式对应的目标匹配波束对后,即可利用调整后的目标下行波束如图10中的波束3向UE发送下行信息;以及,接收UE利用调整后的目标上行波束如图10中的波束b发送的信息。
参见图15根据一示例性实施例示出的另一种传输信息的方法流程图,所述方法还包括:
在步骤25中,获取所述预设工作模式变化对应的所述目标波束偏差信息,生成一条波束偏差记录;
在步骤26中,存储所述波束偏差记录。
本公开中,基站会根据自身与预设类型UE通信时遇到工作模式变化的应用场景所确定的目标波束偏差信息,生成一条针对上述预设类型UE的波束偏差记录,并在本地存储,或者,将所述波束偏差记录发送至云端服务器进行存储,以便以后基站、UE或云端服务器利用上述波束偏差记录作为样本数据训练波束偏差预测模型。
参见图16根据一示例性实施例示出的另一种传输信息的方法流程图,所述方法还可以包括:
在步骤27中,确定已存储的波束偏差历史记录的数量;
在步骤28中,当所述波束偏差历史记录的数量超过预设数量阈值时,利用所述波束偏差历史记录确定所述用户设备的设备类型对应的波束偏差预测模型。
该实施例与上述UE利用满足数量要求的波束偏差历史记录数据训练波束偏差预测模型类似,此处不再赘述。
需要说明的是,在用户设备的存储资源充足、数据处理能力满足处理要求的情况下,也可以存***束偏差记录以及确定波束偏差预测模型,还可以将波束偏差记录或确定的波束偏差预测模型上传至云端服务器。
综上,采用本公开提供的传输信息的方法,在UE和基站利用高频波束传输信息时,若基站和UE之间的匹配波束对需要频繁变化,即表示基站和UE之间相互配合的工作模式发生频繁变化,如UE相对于基站高速移动的应用场景中,若采用波束扫描方式实时确定最佳匹配波束对,由于每一次波束扫描都需要花费一段时间,导致信息传输端确定最佳匹配波束对的效率匹配不上UE高速移动导致的波束对变化率,还会浪费大量功耗。针对上述情况,本公开中,信息传输端可以在工作模式发生变化之前预先确定适用于预设工作模式变化的波束偏差配置信息;当上述预设工作模式变化发生时,即基站和UE之间由第一预设工作模式切换至第二预设工作模式时,信息传输端可以直接根据预先确定的波束偏差配置信息对第一预设工作模式下的初始匹配 波束对进行调整,获得第二预设工作模式下的最佳匹配波束对。由于上述波束对调整过程不需要波束扫描,因而可以有效提高波束对调整效率,以适应波速对需要频繁变化的应用场景,如提高信息传输端对高速移动应用场景的适应能力,确保UE和基站在上述应用场景中的信息传输性能,节约UE进行实时波束扫描所需的信令开销,以及节约UE和基站的功耗。
