- UE Assistance Information UE Assistance Information
- the network device sends an RRC connection reconfiguration message to the UE.
- the RRC connection reconfiguration message includes: configuration information related to overheating.
- the configuration information related to overheating may indicate whether the UE can send auxiliary information related to overheating to the network device, and the value of the prohibition timer related to overheating.
- the network device configures the terminal device to send auxiliary information related to overheating, when the UE has an overheating problem and the prohibition timer related to overheating is not in the running state, the UE executes S102.
- the UE sends an auxiliary information message to the network device.
- the auxiliary information message includes auxiliary information related to overheating, which is used for network equipment to solve the overheating problem of terminal equipment.
- the content of the auxiliary information related to overheating may be configured according to actual requirements, which is not specifically limited in the embodiment of the present application.
- the auxiliary information related to overheating includes the UE type or the number of MIMO layers, it is used to indicate that the UE desires to reduce the number of MIMO layers.
- the network device can reconfigure the appropriate number of MIMO layers for the UE according to the UE type or the number of MIMO layers reported by the UE.
- the network device only reconfigures the number of MIMO layers according to the report of the UE.
- the reduced number of MIMO layers of the UE has disadvantages in closing the radio link and antenna ports, which will affect the SRS capability of the UE under normal capabilities. For example, if the network equipment configures the UE to reduce the maximum number of uplink MIMO layers, the UE will close the transmit radio link. At this time, the UE cannot support the SRS transmission of the antenna under the normal capability, resulting in a waste of some SRS resources. If the network equipment configures the UE to reduce the maximum number of downlink MIMO layers, the UE will close part of the receiving radio link.
- the UE still transmits SRS according to the antenna rotation under normal capabilities, which will cause the network equipment to schedule physical downlinks based on the channel quality estimated by the SRS
- the downlink channel quality of the physical downlink shared channel (PDSCH) transmission is inconsistent. Therefore, even if the network equipment reconfigures the low-capacity MIMO layer number for the UE, the UE still has to maintain the original number of RF links and antenna ports in order to achieve the SRS antenna conversion capability. The power consumption of the UE cannot be reduced.
- the configured low-capacity MIMO layer number can not play the role of cooling down.
- the network device reconfigures the MIMO layer and SRS resources for antenna switching for the UE, so that the UE reduces the MIMO layer capability and antenna switching capability, so that the UE power consumption can solve the overheating problem. Therefore, in the scenario where the UE capability is backed off, how to feed back the backed-off SRS capability supported by the UE to the network equipment also needs to be solved urgently.
- the embodiment of the present application provides a method for reporting SRS capability.
- the basic principle is that the UE reports the fallback SRS capability corresponding to the frequency band combination determined by its frequency band configuration information to the network device, so that the network device is based on the UE reported
- the fallback SRS capability is configured for the UE to meet performance and network requirements.

Description
本申请实施例涉及通信技术领域,尤其涉及一种上报探测参考信号(Sounding Reference Signal,SRS)能力的方法、装置及系统。
随着通信技术的飞速发展,用户设备(user equipment,UE)的功能日益强大。UE工作过程中,不可避免会出现通过降低能力或配置以满足使用需求的情况。例如,UE出现过热问题时,可以通过降低UE的能力或配置,以降低UE温度解决过热问题。
目前,UE向网络设备(例如基站)上报过热相关的UE辅助信息(UE Assistance Information),用于通知UE期望降低的能力或配置,网络设备根据该辅助信息对UE的配置进行重配,解决UE的过热问题。当过热相关的辅助信息包括UE的多输入多输出(multiple input multiple output,MIMO)层(layer)数时,网络设备可以为UE重新配置低能力的MIMO layer数,用于UE按低能力的MIMO layer数关闭部分射频链路及天线端口,以降低UE的功耗解决过热问题。

本申请实施例的技术方案可以应用于各种通信系统,例如:长期演进(long term Evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)、通用移动通信系统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)通信系统、未来的第五代(5th generation,5G)系统或新无线(new radio,NR)等。

在描述本申请的具体方案之前,此处先对本申请涉及的名词进行描述。
SRS能力,也可以称为SRS天线转换能力(SRS Tx switch capability),是指UE支持的轮发SRS的能力,也即UE支持的SRS发射天线端口转换的模式。例如,SRS能力可以为2T4R,表示2发射天线端口和4接收天线端口,即通过2个发射链路在4个链路轮发SRS。

需要说明的是,本申请的方案还可以涉及调整天线端口数的场景,具体实现过程可以参考调整MIMO层数的过程,将本文中描述的MIMO层数替换为天线端口数即可,后续不再一一说明。
在无线通信网络中,会出现通过降低UE的能力或配置以满足使用需求的情况,例如,UE出现过热问题时,或者,UE需要降低功耗时。此处以UE出现过热问题为例描述当前UE能力或配置的过程。UE可以上报UE辅助信息(UE Assistance Information)通知网络设备该UE期望降低的能力或配置,供基站参考、进行重配。图1示意了一种降低UE能力或配置的过程,可以包括下述步骤:
S101、网络设备向UE发送RRC连接重配消息。
其中,该RRC连接重配置消息包括:过热相关的配置信息。例如,过热相关的配置信息可以指示UE是否可以发送过热相关的辅助信息给网络设备,以及过热相关的禁止定时器的取值等。
若网络设备配置终端设备可以发送过热相关的辅助信息,当UE出现过热问题,且过热相关的禁止定时器不在运行状态,UE执行S102。
S102、UE向网络设备发送辅助信息消息。
其中,该辅助信息消息中包括过热相关的辅助信息,用于网络设备解决终端设备的过热问题。
具体的,过热相关的辅助信息的内容可以根据实际需求配置,本申请实施例对此并不进行具体限定。当过热相关的辅助信息包括UE类型或MIMO layer数时,用于指示UE期望降低MIMO layer数。网络设备可以根据UE上报的UE类型或MIMO layer数,给UE重新配置合适的MIMO layer数。
在上述降低UE能力或配置的过程中,网络设备根据UE的上报仅重新配置MIMO layer数,UE降低的MIMO layer数关闭射频链路及天线端口存在弊端,会影响UE正常能力下的SRS能力。比如,若网络设备配置UE降低上行最大MIMO layer数,UE会关闭发射射频链路,这时,UE无法支持正常能力下的天线轮发SRS,从而导致某些SRS资源的浪费。若网络设备配置UE降低下行最大MIMO layer数,UE会关闭部分接收射频链路,这时UE仍然按照正常能力下的天线轮发SRS,就会导致网络设备根据SRS估计的信道质量与调度物理下行共享信道(physical downlink shared channel,PDSCH)传输的下行信道质量不一致。因此,即使网络设备为UE重配了低能力的MIMO layer数,UE为了实现SRS天线转换能力,仍然要保持原来的射频链路及天线端口数目,UE的功耗无法降低,网络设备为UE重新配置的低能力的MIMO layer数也无法发挥降温的作用。
在该场景下,网络设备为UE重配MIMO layer以及用于天线转换的SRS资源,使得UE降低MIMO layer能力以及降低天线转换能力,才能UE功耗解决过热问题。因此,在回退UE能力的场景下,如何将UE支持的回退SRS能力反馈给网络设备也急需解决。
基于此,本申请实施例提供了一种上报SRS能力的方法,其基本原理是:UE将其频带配置信息确定的频带组合对应的回退SRS能力上报给网络设备,使得网络设备基于UE上报的回退SRS能力为UE进行配置,满足性能及网络需求。
需要说明的是,本申请实施例提供的方案可以应用于任一UE需上报回退SRS能力的场景中,UE发 生过热问题或者需降低功耗仅是示例的应用场景,并不是对本申请方案的应用场景的具体限定,后续内容对此不再一一说明。
本申请提供的上报SRS能力的方法,应用于如图2所示的无线通信系统架构中。如图2所示,该无线通信系统架构中包括至少一个网络设备201,以及与网络设备201进行通信的UE 202。
需要说明的是,图2仅仅是通过举例对无线通信系统架构的示意。对于无线通信系统架构中包括的网络设备201的数量及类型、UE 202数量及类型等,均可以根据实际需求配置,图2并不是对此内容的具体限定。

一种可能的实现中,第一频带组合为:UE的频带配置信息对应的第一配置对应的一个或多个频带组合。
另一种可能的实现中,第一频带组合为:UE的频带配置信息对应的第一配置的一个或多个回退配置对应的频带组合。

需要说明的是,对于第一频带组合中的具体内容,可以根据实际需求配置,本申请不进行具体限定。例如,对于UE的配置不做更改的场景,第一频带组合中可以包括第一配置对应的一个或多个频带组合。例如,对于UE的配置可能回退的场景,第一频带组合中可以包括第一配置的回退配置对应的一个或多个频带组合。
其中,UE的频带配置信息用于指示UE当前的配置。UE的频带配置信息对应的第一配置可以为UE当前的配置,也即UE正在当前的配置上工作。例如,第一配置可以为UE执行S321时UE所具有的配置。或者,第一配置可以为UE的某一种特定配置,本申请实施例对此不进行具体限定。
具体的,频带配置信息用于确定UE在第一配置下的频带组合,频带配置信息可以包括下述信息中的一项或多项:载波信息、带宽信息。当然,频带配置信息也可以为其他内容,本申请实施例对此并不进行具体限定。
其中,载波信息是指用于指示载波的信息。例如,载波信息可以为载波标识(identity,ID),或者,也可以为载波数量,或者可以为载波的频点信息,或者可以为载波的带宽信息,或者其他。凡是可以用于指示载波的信息,都可以作为本文所称的载波信息。
带宽信息是指用于指示带宽的信息。例如,带宽信息可以为带宽的数值,或者,也可以为带宽的编号,或者其他。凡是可以用于指示带宽的信息,都可以作为本文所称的带宽信息。
示例性的,假设频带配置信息为载波的数量、每个载波的频点信息和带宽信息,即可确定出一个或多个频带,根据频带与频带组合的对应关系,进而确定出频带配置信息对应的第一配置的一个或多个频带组合。
需要说明的是,上述示例只是通过举例的形式对于S321中根据频带配置信息确定对应的第一配置的一个或多个频带组合进行说明,并不是对该过程的具体限定。
一种可能的实现中,UE的频带配置信息由网络设备下发,相应的,如图5所示,本申请实施例提供的上报SRS能力的方法还包括包括S321a和S321b。
S321a、网络设备向UE发送频带配置信息。
具体的,网络设备通过发送上述频带配置信息指示UE按照该频带配置信息工作。因此,UE当前工作在网络设备发送的频带配置信息对应的第一配置。
S321b、UE接收网络设备发送的频带配置信息。
进一步的,每一种UE的配置与其对应的回退SRS能力可以预先配置映射关系,在S321中查找该映射关系即可获取第一配置对应的回退配置。当然,也可以通过其他方式获取第一配置对应的回退配置,本申请实施例对此不进行具体限定。示例性的,根据回退的载波的数量、每个载波的频点信息和回退的带宽信息,即可确定出一个或多个频带,根据频带与频带组合的对应关系,进而确定出频带配置信息对应的第一配置的回退配置的一个或多个频带组合。
S322、UE确定第一SRS能力信息。
其中,第一SRS能力信息与第一频带组合对应。第一SRS能力信息,可以为UE在第一频带组合中的每个频带组合中的每个频带支持的回退SRS能力信息,两者可相互替代,后续内容不再一一说明。
具体的,SRS能力信息是用于指示SRS能力的信息,本申请实施例对于SRS能力的信息的内容及形式不进行具体限定。
示例性的,SRS能力信息用于指示SRS能力,SRS能力信息可以为SRS能力的具体数值,或者,也可以为SRS能力的ID,或者其他,本申请实施例对此不进行具体限定。
具体的,S322具体可以通过但不限于下述两种实现方式来实现:
实现方式1、可以预先配置UE在每一种频带支持的回退SRS能力,在S322中UE根据预先配置的内容,先确定UE在第一频带组合中的每个频带组合的每个频带支持的SRS转换能力,进而确定UE在第一频带组合中的每个频带组合的每个频带支持的SRS能力信息,作为第一SRS能力信息。
实现方式2、可以预先配置UE在每一种频带支持的回退SRS能力信息,在S322中UE根据预先配置的内容,即可直接确定UE在第一频带组合中的每个频带组合的每个频带支持的SRS能力信息,作为第一SRS能力信息。
具体的,根据第一频带组合包括的频带组合的数量不同,第一SRS能力信息可以包括但不限于下述两种情况:
情况A、第一频带组合为第一配置对应的一个频带组合,第一SRS能力信息按照第一频带组合中的频带的默认顺序排列。
UE和网络设备都知道第一配置,第一SRS能力信息,按照第一频带组合中的频带的默认顺序排列。第一SRS能力信息中无需体现SRS能力信息与频带的对应关系,网络设备根据第一频带组合中的频带的默认顺序,即可确定SRS能力信息与频带的对应关系,即确定UE在哪个频带支持的回退SRS能力信息是哪个。
其中,默认顺序可以为预先规定的频带组合中频带的顺序,或者,默认顺序也可以为UE开机上报的能力信息中频带组合中频带的顺序,或者其他,本申请实施例对此不进行具体限定。
例如,假设第一频带组合只包括频带组合X,频带组合X中包括频带1、频带2、频带3。假设UE开机上报的能力信息中频带组合X中频带的顺序为频带1、频带3、频带2,那么与频带组合X对应的第一SRS能力信息的顺序可以为:UE在频带1支持的回退SRS能力信息、UE在频带3支持的回退SRS能力信息、UE在频带2支持的回退SRS能力信息。
情况B、第一频带组合包括一个或多个频带组合。
在情况B中,第一SRS能力信息可以包括:第一频带组合中的频带组合,以及与第一频带组合中的频带组合一一对应的SRS能力信息。应理解,在情况B中,第一SRS能力信息中的SRS能力信息与第一频带组合中的频带组合一一对应,用于向网络设备指示SRS能力信息与频带组合的对应关系,网络设备根据频带组合中的频带的默认顺序确定UE在哪个频带支持的SRS能力信息是哪个。
例如,假设第一频带组合包括频带组合A和频带组合B,频带组合A中包括频带1、频带2、频带3,频带组合B中包括频带4、频带5、频带6。假设UE开机上报的能力信息中频带组合A中频带的顺序为频带1、频带3、频带2,频带组合B中频带的顺序为频带4、频带5、频带6。第一SRS能力信息可以为:{频带组合A,UE在频带1支持的回退SRS能力信息、UE在频带3支持的回退SRS能力信息、UE在频带2支持的回退SRS能力信息}、{频带组合B,UE在频带4支持的回退SRS能力信息、UE在频带5支持的回退SRS能力信息、UE在频带6支持的回退SRS能力信息}。
情况C、第一频带组合包括一个或多个频带组合。
在情况C中,第一SRS能力信息可以包括:第一频带组合中的频带组合,以及与第一频带组合中的频带组合中的频带一一对应的SRS能力信息。应理解,在情况C中,第一SRS能力信息中将在频带支持的SRS能力信息与频带一一对应,用于向网络设备指示SRS能力信息与频带的对应关系,以使得网络设备确定UE在哪个频带支持的SRS换能力信息是哪个。
例如,假设第一频带组合包括频带组合A和频带组合B,频带组合A中包括频带1、频带2、频带3,频带组合B中包括频带4、频带5、频带6。第一SRS能力信息可以为:{频带组合A,频带1,UE在频带1支持的回退SRS能力信息}、{频带组合A,频带2,UE在频带2支持的回退SRS能力信息}、{频带组合A,频带3,UE在频带3支持的回退SRS能力信息}、{频带组合B,频带4,UE在频带4支持的回退SRS能力信息}、{频带组合B,频带5,UE在频带5支持的回退SRS能力信息}、{频带组合B,频带6,UE在频带6支持的回退SRS能力信息}。
需要说明的是,上述示例只是通过举例的形式描述第一SRS能力信息与频带组合的对应关系,并不是对第一SRS能力信息内容的限定。
进一步的,由于SRS能力与MIMO层数都和UE的链路性能相关,降低UE的能力与配置时可以两者都降低,如图5所示,本申请实施例提供的上报SRS能力的方法还可以包括S322a。
S322a、UE向网络设备发送MIMO层数信息。
其中,MIMO层数信息,用于指示UE请求回退的MIMO层数。MIMO层数信息可以用于网络设备向UE配置回退的MIMO能力。UE期望的MIMO层数可以为一种或者多种。MIMO层数信息包括:UE期望的MIMO层数的最大值,或者,UE期望的MIMO层数的绝对值。
具体的,当MIMO层数信息包括UE期望的MIMO层数的绝对值时,UE请求网络设备向其配置MIMO层数信息指示的MIMO层数,此时UE期望的MIMO层数为一种。当MIMO层数信息包括UE期望的MIMO层数的最大值时,UE请求网络设备向其配置小于或等于MIMO层数信息指示的MIMO层数,此时UE期望的MIMO层数为一种或多种。
需要说明的是,UE可以根据网络需求或者场景需求,来确定回退的MIMO的层数,进而确定MIMO层数信息,本申请实施例对于该过程不进行具体限定。
例如,UE可以在发生过热时,根据当前设备温度以及理想温度,得到期望降低的功耗值,再按照预设的功耗与MIMO层数的映射关系,确定回退的MIMO的层数,进而确定MIMO层数信息。当然,此处只是以过热场景下的一种实现举例,并不对应用场景以及实现方式构成限定。
具体的,UE期望的MIMO层数可以包括下述内容中一种或多种:上行MIMO层数、下行MIMO层数、高频MIMO层数、低频MIMO层数、高频上行MIMO层数、高频下行MIMO层数、低频上行MIMO层数、低频下行MIMO层数。
进一步的,当本申请提供的上报SRS能力的方法还包括S322a时,第一SRS能力信息,具体可以实现为:UE在第一频带组合中的频带组合下,UE期望的一种或多种MIMO层数支持的SRS能力信息。
需要说明的是,MIMO层数可以有多种维度,包括但不限于上行、下行、高频、低频等,UE在第一频带组合中的每个频带组合下,一种或多种UE期望的MIMO层数的不同维度组合可以支持不同的SRS能力信息;或者,UE在第一频带组合中的每个频带组合下,一种或多种UE期望的MIMO层数的不同维度组合可以支持相同的SRS能力信息。其中,维度组合是指一种或多种维度的结合。具体的,UE在UE期望的MIMO层数支持的SRS能力信息可以为UE在UE期望的上行MIMO层数和下行MIMO层数的组合对应的SRS能力信息。
具体的,当本申请提供的上报SRS能力的方法还包括S322a时,第一SRS能力信息具体可以包括但不限于下述几种情况:
第一种情况、第一频带组合只包括一个频带组合,UE在不同的MIMO层数支持相同的SRS能力,第一SRS能力信息可以仅包括:UE在第一频带组合中的频带组合支持的SRS能力信息,且按照第一频带组合中的频带的默认顺序排列,具体实现可以参考上述情况A的实现,此处不再赘述。
第二种情况、第一频带组合包括一个或多个频带组合,UE在不同的MIMO层数支持相同的SRS能力,第一SRS能力信息可以仅包括:第一频带组合中的频带组合,以及与频带组合或者频带组合中的频带一一对应的回退SRS能力信息。具体实现可以参考上述情况B、情况C的实现,此处不再赘述。
第三种情况、第一频带组合包括一个或多个频带组合,UE在不同的MIMO层数支持不同的SRS能力,第一SRS能力信息与第一频带组合对应,具体可以实现为:第一SRS能力信息与第一频带组合中的频带组合、UE期望的多输入多输出MIMO层数对应。
在第三种情况中,第一SRS能力信息可以包括:第一频带组合中的频带组合、以及与频带组合和UE期望的MIMO层数对应的SRS能力信息。其中,当UE期望的MIMO层数为多种时,此处描述的UE期望的MIMO层数是指UE期望的一种或多种MIMO层数。
第四种情况、第一频带组合包括一个或多个频带组合,UE在不同的MIMO层数支持不同的SRS能力,第一SRS换能力信息可以包括:第一频带组合中的频带组合、以及与频带组合中的频带和UE期望的MIMO层数对应的SRS能力信息。其中,当UE期望的MIMO层数为多种时,此处描述的UE期望的MIMO层数是指UE期望的一种或多种MIMO层数。
另一种可能的实现中,当UE既降低SRS能力又降低MIMO层数,第一SRS换能力信息可以包括:第一频带组合中的频带组合、UE期望的MIMO层数、以及与频带组合中的频带和UE期望的MIMO层数对应的SRS能力信息。即通过第一SRS能力信息上报了回退的SRS能力及期望的MIMO层数。在该实现中,UE期望的MIMO层数可以通过MIMO层数信息实现。在该实现中,无需S322a。
S323、UE向网络设备发送第一SRS能力信息。
需要说明的是,对于第一SRS能力信息,已经在前述内容进行了详细说明,此处不再进行赘述。
一种可能的实现中,当本申请提供的上报SRS能力的方法还包括S322a时,S323和S322a可以使用同一条RRC消息实现,例如,UE向网络设备发送包括MIMO层数信息以及第一SRS能力信息的RRC消息。
另一种可能的实现中,当本申请提供的上报SRS能力的方法还包括S322a时,S322a可以实现为:UE向网络设备发送包括MIMO层数信息的第一RRC消息,S323可以实现为:UE向网络设备发送包括第一SRS能力信息的第二RRC消息。
例如,上述RRC消息可以为终端设备辅助消息(UE assistance information)。
S324、网络设备接收UE发送的第一SRS能力信息。

具体的,在325中,网络设备可以根据自身配置的规则确定是否根据第一SRS能力信息配置UE,该规则可以由管理员配置或者其他方式配置,本申请对于规则的配置方法以及规则内容不进行具体限定。
若S325中,网络设备确定按照第一SRS能力信息配置UE,执行326和S327;若S325中,网络设备确定不按照第一SRS能力信息配置UE,即网络设备不改变当前的配置,网络设备可以不向UE发送配置消息,结束流程。
S326、网络设备向UE发送配置消息。
具体的,在S326中,网络设备根据接收的第一SRS能力信息以及当前业务场景,确定UE的配置,向UE发送配置消息。
可选的,在S326中,网络设备可以为UE配置SRS资源,和/或,MIMO层数。当然,网络设备也可以配置其他,本申请对此不进行具体限定,对于配置的具体过程不进行赘述。

进一步的,如图5所示,在S321之前,本申请实施例提供的上报SRS能力的方法还可以包括S328和S329。
S328、UE向网络设备发送第二SRS能力信息。
其中,第二SRS能力信息与第一SRS能力信息不同。第二SRS能力信息可以为UE开机时上报的能力信息。第一SRS能力信息可以为第二SRS能力信息回退或者降低的能力信息。
S329、网络设备接收第二SRS能力信息。
需要说明的是,本申请实施例提供的上报SRS能力的方法所包括的上述步骤,可以根据实际需求配置执行顺序,图4及图5中仅示意了一种可能的执行顺序,并不是对此的具体限定。
还需要说明的是,图4及图5示意的未在权利要求中描述的步骤,均为可选步骤,可以根据实际需求选择执行。
本申请提供的上报SRS能力的方法,将UE的频带配置信息确定的频带组合对应的SRS能力信息上报给网络设备,实现当UE在频带配置信息对应的第一配置工作时,网络设备基于UE上报的SRS能力为UE进行相关配置。例如,在UE过热场景下,在回退MIMO层数的基础上,网络设备基于UE上报的SRS能力为UE配置回退的SRS能力,有效降低功耗解决过热问题。或者,在降功耗场景,在回退MIMO层数的基础上,网络设备基于UE上报的SRS能力为UE配置回退的SRS能力,有效降低功耗。需要说明的是,本申请实施例对于应用场景不进行具体限定。
