Description

一种通信方法、通信装置及网络设备 技术领域
本申请通信技术领域，尤其涉及一种通信方法、通信装置及网络设备。
背景技术
随着无线通信技术的发展，各种新的业务层出不穷，不同业务对资源的需求也不同，这就要求在未来无线网络中各种业务要能够更加高效地使用有限的信道资源。在长期演进系统(long term evolution，简称LTE)和5G新无线技术(new radio，简称NR)系统中，探测参考信号(sounding reference signal，简称SRS)是很重要的上行信号。用户设备(user equipment，简称UE)与基站建立连接后，基站可以为UE分配SRS资源，然后通过UE发送的SRS来估计上行信道质量。特别的，在时分双工系统中，基于上下行信道的互易性，基站还可根据UE发送的SRS估计下行信道质量，进而进行下行波束赋形。由于无线通信信道的时变特征，若当前配置的周期发送的SRS或半静态发送的SRS的发送周期越长，则SRS信噪比会越弱，进而影响用户的信道估计及吞吐率，但是发送周期越短，则SRS资源不足以给每个用户都分配使用。
在现有技术中，每个小区内用户理论上可使用的SRS资源范围是有限的，基站在为小区内的用户分配SRS资源的时候，往往仅考虑用户接入时上报的能力指示信息和基站资源现状，为用户分配可使用的SRS资源范围内尚未分配的SRS资源。这种仅在用户接入时进行一次性分配的方式对于SRS资源使用的灵活性和利用效率都较差。
发明内容
本申请实施例所要解决的技术问题在于，提供一种通信方法、通信装置及网络，以解决SRS资源有限，分配不灵活，利用效率较差的问题。
第一方面，本申请的实施例提供了一种通信方法，可包括：
终端向网络设备发送第一指示信息，所述第一指示信息指示更新的所述终端支持的SRS发送端口切换模式，所述更新的所述终端支持的SRS发送端口切换模式包括至少一种天线切换能力；

请参照图1，为本申请实施例中一种通信系统的架构示意图。其中可以包括网络设备和通信装置，为了便于说明，在图1中以网络设备为基站10、通信装置为终端20进行举例说明，在该架构下，可以包括基站10和至少一个终端20。
其中，网络设备可以是指接入网中在空中接口上通过扇区与终端通信连接的设备。网络设备可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分包括IP网络。网络设备还可协调对空中接口的属性管理。例如，网络设备可以是全球移动通信系统(Global System for Mobile Communication，简称GSM)或码分多址技术(Code Division Multiple Access，简称CDMA)中的基站(Base Transceiver Station，简称BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，简称WCDMA)中的基站，还可以是LTE中的演进型基站，或者还可以是无线局域(Wireless Local Area Networks，简称WLAN)中的接入点(Access Point，简称AP)，中继站，车载设备，可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备，例如可以连接5G核心网设备的基站，传输与接收点(Transmission and Reception Point，简称TRP)，集中式处理单元(Centralized Unit，简称CU)，分布式处理单元(Distributed Unit，简称DU)等。此处不做限定。
以网络设备为基站为例，基站10可以是NR基站(gNB)、演进型节点B(evolved Node B，简称eNB)、节点B(Node B，简称NB)、基站控制器(Base Station Controller，简称BSC)、基站收发台(Base Transceiver Station,简称BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，简称HNB)、基带单元(BaseBand Unit，简称BBU)等。其也可以被本领域技术人员称之为基站收发机、无线基站、无线收发机、收发机功能、基站子系统(Base Station Sub system，简称BSS)或者一些其它适当的术语。其是网络侧一种用于发射信号或接收信号的实体。在本申请实施例中，基站10可以接收终端发送的指示信息，根据总体SRS资源的使用现状和终端发送的指示信息来进行决策，确定为终端分配的SRS资源。

为了描述简便，本申请实施例仅示出了一个终端20，在实际场景中，终端20的数量可以是一个或多个，一些终端还可以作为中转设备，可以为另外一些终端中转消息，且终端与终端之间还可以组成用户组等，本申请实施例不作任何限定。
下面结合附图2-图8对本发明实施例的通信方法及设备进行详细说明。
请参见图2，图2为本申请实施例提供的一种通信方法的流程示意图。包括如下步骤：
S201，终端向基站发送第一指示信息。
其中，所述第一指示信息指示更新的所述终端支持的SRS发送端口切换模式，所述更新的所述终端支持的SRS发送端口切换模式包括至少一种天线切换能力。
S202，所述终端接收来自所述基站的天线切换类型SRS资源配置信息。
在步骤S201中，当终端接入基站之后，终端的工作状态可能是动态变化的，外部环境也可能是动态变化的。这样，导致终端对SRS资源的需求也会发生变化。例如，随着终端的工作时长的不断延续，终端的电量会逐步降低，当降低到某个电量阈值时终端可以进入节能模式，此时终端对SRS资源的需求也可能相应的降低，而当终端充电，电量恢复到电量阈值之上，此时终端对SRS资源的需求也可能相应的升高。因此，可以通过第一指示信息来通知基站，终端当前对SRS资源的需求。
在一种可能的实现方式中，所述终端在初始接入时支持的SRS发送端口切换模式可以通过supportedSRS-TxPortSwitch信元来指示。例如其用于指示天线切换能力的字段可以是：t1r1-t1r2、t1r1-t1r2-t1r4、t1r1-t1r2-t2r2-t2r4、t1r1-t1r2-t2r2-t1r4-t2r4、t1r1-t2r2、t1r1-t2r2-t4r4等，当该字段为t1r1-t1r2时，表示终端支持t1r1和t1r2两种天线切换能力。t1r1代表终端支持1发1收的天线切换能力，t1r2表示终端支持1发2收的天线切换能力。
当supportedSRS-TxPortSwitch信元中的字段为notsupport时，表示终端不支持天线切换(antenna switching，简称AS)类型的SRS。
当终端确定满足预设条件时，可以向基站发送第一指示信息，以便于基站根据终端发送的第一指示信息来动态调整SRS资源的分配。例如，终端可以通过ReducedMaxSrs-TxPortSwitch信元或IncreasedMaxSrs-TxPortSwitch上报更新的终端支持的SRS发送端口切换模式，以使得基站对应的减少SRS资源的分配或增加SRS资源的分 配。
示例性的，天线切换能力对应的SRS资源，可以理解为基站为了使得终端工作在某种天线切换能力时，为该终端分配的SRS资源，该SRS资源可以包括n个SRS资源，n个SRS资源中的每个SRS资源可以对应m个端口，所以，天线切换能力对应的SRS资源的大小可以按照n乘以m(n*m)的乘积来衡量，乘积越大，该天线切换能力对应的SRS资源越大。
示例性的，天线切换能力与SRS资源对应，即当终端工作在某种天线切换能力时，基站可以为终端分配与该天线切换能力对应的SRS资源。天线切换能力对应的SRS资源的大小与SRS资源的数目以及SRS资源的端口数有关。通常基站为终端分配的SRS资源的个数n和每个SRS资源的端口数m，该n和m所对应的终端的天线切换能力t xr y必须属于更新的终端支持的SRS发送端口切换模式中的其中一种。一般来说，m＝x,n＝y/x。例如终端更新的天线切换能力为t1r2，则按照此能力分配的SRS的AS资源的个数n等于2，每个SRS资源的发送端口数等于1。
在另一种可能的实现方式中，终端在初始接入时可以向基站上报终端支持的码本(code book，简称CB)类型SRS的最大上行多输入多输出(multiple input multiple output，简称MIMO)层数，例如可以通过maxNumberMIMO-LayersCB-PUSCH信元上报初始的终端支持的CB类型SRS的最大上行MIMO层数，maxNumberMIMO-LayersCB-PUSCH可能取值如下：
oneLayer,twoLayers,fourLayers。oneLayer表示终端支持的最大上行MIMO层数为1层，twoLayers表示终端支持的最大上行MIMO层数为2层，fourLayers表示终端支持的最大上行MIMO层数为4层。当终端确定满足预设条件时，可以向基站发送第一指示信息，以便于基站根据终端发送的第一指示信息来动态调整SRS资源的分配。例如，终端可以通过ReducedMaxMIMO-Layers信元或IncreasedMaxMIMO-Layers上报更新的终端支持的最大上行MIMO层数，以使得基站对应的减少SRS资源的分配或增加SRS资源的分配。
其中，若基站为终端分配的CB类型SRS资源的端口数为m，该m小于等于终端支持的最大上行MIMO层数。一般来说，基站会给终端分配一个CB类型的SRS资源，即n＝1。假设终端支持的最大上行MIMO层数为twoLayers，则基站为终端分配的SRS资源的端口数m为1或者2。
在另一种可能的实现方式中，终端在初始接入时可以向基站上报终端支持的非码本(non code book，简称nonCB)类型SRS的最大上行多输入多输出(multiple input multiple output，简称MIMO)层数，例如可以通过maxNumberMIMO-LayersNonCB-PUSCH信元上报初始的终端支持的CB类型SRS的最大上行MIMO层数，maxNumberMIMO-LayersNonCB-PUSCH可能取值如下：
oneLayer,twoLayers,fourLayers。oneLayer表示终端支持的最大上行MIMO层数为1层，twoLayers表示终端支持的最大上行MIMO层数为2层，fourLayers表示终端支持的最大上行MIMO层数为4层。当终端确定满足预设条件时，可以向基站发送第一指示信息，以便于基站根据终端发送的第一指示信息来动态调整SRS资源的分配。例如，终端可以通过ReducedMaxMIMO-Layers信元或IncreasedMaxMIMO-Layers上报更新的终端支持的最大上行MIMO层数，以使得基站对应的减少SRS资源的分配或增加SRS资源的分配。
其中，若基站为终端分配的nonCB类型SRS资源的端口数为m，该m小于等于终端支 持的最大上行MIMO层数。一般来说，基站会给终端分配一个nonCB类型的SRS资源，即n＝1。假设终端支持的最大上行MIMO层数为twoLayers，则基站为终端分配的SRS资源的端口数m为1或者2。
上述三种可能的实现方式可以同时进行，也可以根据终端支持的SRS类型独立进行，本申请实施例不作任何限定。
在上述三种可能的实现方式中，终端还可以在初始接入时通过maxNumberSRS-Ports-PerResource上报初始的终端能够支持的单个SRS资源对应的最大端口数，maxNumberSRS-Ports-PerResource的可能取值如下：
1,2,4。
当终端确定满足预设条件时，可以向基站发送第一指示信息，以便于基站根据终端发送的第一指示信息来动态调整SRS资源的分配。例如，终端可以通过reducedmaxNumberSRS-Ports-PerResource或IncreasedmaxNumberSRS-Ports-PerResource上报更新的UE能够支持的单个SRS资源对应的最大端口数。以使得基站对应的减少SRS资源的分配或增加SRS资源的分配。
若基站为终端分配的单个任一类型的SRS资源的端口数为m，该m小于等于终端能够支持的单个SRS资源对应的最大端口数。
通常，端口数为2的SRS占用的资源比端口数为1的SRS占用的资源大。但是2个端口数为1的SRS占用的资源和1个端口数为2的SRS占用的资源可以相同。可选地，基站可以定义2个端口数为1的SRS占用的资源比1个端口数为2的SRS占用的资源大。例如资源占用数以t1r1小于t1r2小于t2r2小于t2r4的顺序排序。基站可以灵活的按照终端上报的能力和网络侧SRS资源现状，动态的自适应分配SRS资源，以实现提升SRS资源分配的灵活性及利用率的目的。
可选地，所述第一指示信息可以携带在用户设备辅助信息(UE Assistance Information)中或过热保护信息(Overheating Assistance)中。
在终端完成接入之后，可以根据自身的状态或外部环境的变化动态的触发终端向基站发送指示信息，告知终端当前的能力或终端当前对SRS资源的需求，从而使得基站可以动态调整为终端分配的SRS资源，从而提升了SRS资源分配的灵活性以及SRS资源的利用率。
由于终端的工作状态可能由正常变为非正常，也可能由非正常变为正常，因此对于SRS资源的动态调整也可以分为两大类。下面结合图3和图4进行详细说明。
请参见图3，为本申请实施例提供的另一种通信方法的流程示意图；包括如下步骤：
S301，终端向所述基站发送第二指示信息。
所述第二指示信息指示所述终端支持的SRS发送端口切换模式，所述终端支持的SRS发送端口切换模式包括至少一种天线切换能力，所述终端支持的SRS发送端口切换模式包括的所述至少一种天线切换能力分别对应有SRS资源，其中最大的SRS资源为第一SRS资源。
S302，所述终端接收来自所述基站的第一天线切换类型SRS资源配置信息。
S303，所述终端基于第一天线切换类型SRS资源配置信息分配的SRS资源发送SRS。
S304，若所述终端确定满足预设条件，则向所述基站发送所述第一指示信息。
此时，所述第一指示信息用于减少终端的SRS资源。
由于基站为终端分配SRS资源的算法可以有很多种，因此为了实现减少终端的SRS资源的目的，针对不同的分配SRS资源的算法，可以采用如下不同的方法来实现：
当基站根据终端上报的最大的天线切换能力为终端分配SRS资源时，所述第一指示信息指示更新的所述终端支持的SRS发送端口切换模式，所述更新的所述终端支持的SRS发送端口切换模式包括至少一种天线切换能力，所述更新的所述终端支持的SRS发送端口切换模式包括的至少一种天线切换能力分别对应有SRS资源，其中最大SRS资源小于所述第一SRS资源。此时，为终端分配的SRS资源可以相应的减少。
当然基站为终端分配SRS资源的算法还有很多种，例如基站可根据终端上报的最大的天线切换能力为终端分配SRS资源，也可以根据终端上报的多种天线切换能力的中间值或均值为终端分配SRS资源，还可以根据终端的业务类型如大流量业务/小流量业务、高速业务/低速业务等为终端分配SRS资源。这时，为了确保基站减少为终端分配的SRS资源，所述第一指示信息指示更新的所述终端支持的SRS发送端口切换模式，所述更新的所述终端支持的SRS发送端口切换模式包括至少一种天线切换能力，所述更新的所述终端支持的SRS发送端口切换模式包括的至少一种天线切换能力分别对应的SRS资源均小于所述第一SRS资源。从而使得网络设备无论采用何种分配SRS资源的算法，在其接收到第一指示信息之后，都会为减少分配给终端的SRS资源。
其中，所述预设条件包括以下至少一种：
所述终端的温度达到预设温度；此处预设温度可以为一个值，也可以为多个值，对应的SRS资源的调整也可以分为多个层级。例如终端温度达到40度时，减少SRS资源的分配，达到60度时，可以进一步减少SRS资源的分配。当温度降低时，SRS资源的调整同样可以分为多个层级。
所述终端的电量达到预设电量；此处预设温度可以为一个值，也可以为多个值，对应的SRS资源的调整也可以分为多个层级。例如终端电量降低到20％时，减少SRS资源的分配，降低到5％度时，可以进一步减少SRS资源的分配。当电量升高时，SRS资源的调整同样可以分为多个层级。
所述终端的至少一根天线发生故障。此处可以根据发生故障的天线数目将对应的SRS资源的调整分为多个层级。例如发生故障的天线为1根时，减少SRS资源的分配，发生故障的天线为2根时，可以进一步减少SRS资源的分配。当发生故障的天线恢复正常时，也可以根据恢复正常的天线的根数将SRS资源的调整分为多个层级。
S305，所述终端接收来自所述基站的第二天线切换类型SRS资源配置信息。
所述基站在所述第二天线切换类型SRS资源配置信息中为所述终端分配的SRS资源小于所述终端当前使用的SRS资源。
例如，对于支持t1r1、t2r2和t2r4天线切换能力的AS类型SRS用户，若基站起始为终端分配的SRS资源对应的天线切换能力为t2r4(即2个SRS资源，每个SRS资源对应的端口数为4)，之后可以在终端满足上述预设条件时调整为终端分配的SRS资源。例如，调整后的SRS资源对应的天线切换能力为2t2r(即1个SRS资源，该SRS资源对应的端口数为2)或者1T1R(即1个SRS资源，该SRS资源对应的ports数为1)。
对于CB类型SRS用户，若基站起始为终端分配的SRS资源的端口数为4，之后可以在终端满足上述预设条件时调整为终端分配的SRS资源。例如，调整后的SRS资源的端口数为2或者的端口数为1。
对于nonCB类型SRS用户，若基站起始为终端分配的SRS资源的端口数为4，之后可以在终端满足上述预设条件时调整为终端分配的SRS资源。例如，调整后的SRS资源的端口数为2或者端口数为1。
通过上述的调整方式，可以实现对于能力或者需求降低的终端，动态的减少SRS资源的分配，从而可以扩展基站的用户容量，利于新接入的终端获得足够的SRS资源，提升了SRS分配的灵活性和利用率。
请参见图4，为本申请实施例提供的又一种通信方法的流程示意图；包括如下步骤：
S401，终端向所述网络设备发送第二指示信息。
所述第二指示信息指示所述终端支持的SRS发送端口切换模式，所述终端支持的SRS发送端口切换模式包括至少一种天线切换能力，所述终端支持的SRS发送端口切换模式包括的所述至少一种天线切换能力分别对应有SRS资源，其中最大的SRS资源为第一SRS资源。
S402，若原来满足预设条件的终端确定当前已不满足预设条件，则向所述网络设备发送所述第一指示信息。
此时，所述第一指示信息用于增加终端的SRS资源。
由于基站为终端分配SRS资源的算法可以有很多种，因此为了实现增加终端的SRS资源的目的，针对不同的分配SRS资源的算法，可以采用如下不同的方法来实现：
当基站根据终端上报的最大的天线切换能力为终端分配SRS资源时，所述第一指示信息指示更新的所述终端支持的SRS发送端口切换模式，所述更新的所述终端支持的SRS发送端口切换模式包括至少一种天线切换能力，所述更新的所述终端支持的SRS发送端口切换模式包括的至少一种天线切换能力分别对应有SRS资源，其中最大SRS资源大于所述第一SRS资源。此时，为终端分配的SRS资源可以相应的增加。
当然基站为终端分配SRS资源的算法还有很多种，例如基站可根据终端上报的最大的天线切换能力为终端分配SRS资源，也可以根据终端上报的多种天线切换能力的中间值或均值为终端分配SRS资源，还可以根据终端的业务类型如大流量业务/小流量业务、高速业务/低速业务等为终端分配SRS资源。这时，为了确保基站增加为终端分配的SRS资源，所述第一指示信息指示更新的所述终端支持的SRS发送端口切换模式，所述更新的所述终端支持的SRS发送端口切换模式包括至少一种天线切换能力，所述更新的所述终端支持的SRS发送端口切换模式包括的至少一种天线切换能力分别对应的SRS资源均大于所述第一SRS资源。
从而使得网络设备无论采用何种分配SRS资源的算法，在其接收到第一指示信息之后，都会为增加分配给终端的SRS资源。
所述预设条件包括以下至少一种：
所述终端的温度达到预设温度；
所述终端的电量达到预设电量；
所述终端的至少一根天线发生故障；
所述终端接入所述基站的时间低于预设时间。此处预设时间可以为一个值，也可以为多个值，对应的SRS资源的调整也可以分为多个层级。
S403，所述终端接收来自所述基站的天线切换类型SRS资源配置信息。
所述基站在所述天线切换类型SRS资源配置信息中为所述终端分配的SRS资源大于所述终端当前使用的SRS资源。
例如，对于支持t1r1和t2r2天线切换能力的AS类型SRS用户，若基站起始为终端分配的SRS资源对应的天线切换能力为t2r2(即1个SRS资源，每个SRS资源对应的端口数为2)，之后可以在终端不满足上述预设条件时调整为终端分配的SRS资源。例如，调整后的SRS资源对应的天线切换能力为2t4r(即2个SRS资源，该SRS资源对应的端口数为4)。
对于CB类型SRS用户，若基站起始为终端分配的SRS资源的端口数为1，之后可以在终端不满足上述预设条件时调整为终端分配的SRS资源。例如，调整后的SRS资源的端口数为2或者的端口数为4。
对于nonCB类型SRS用户，若基站起始为终端分配的SRS资源的端口数为1，之后可以在终端不满足上述预设条件时调整为终端分配的SRS资源。例如，调整后的SRS资源的端口数为2或者端口数为4。
通过上述的调整方式，可以实现对于能力或者需求提升或恢复的终端，可以动态的增加SRS资源的分配，从而可以提升终端的吞吐量和通信质量，提升了SRS分配的灵活性和利用率。
当终端再次满足上述的预设条件时，可以参照图3所述实施例中的步骤，再次发送指示信息，以使得基站减少SRS资源的分配。
需要说明的是，在本申请图3和图4所述的实施例中，通常在终端能力降低时减少SRS资源的分配，在终端能力提升时增加SRS资源的分配，在其他的一些通信场景如卫星通信场景中，为了确保终端通信的质量和通信的正常进行，也可以在终端能力降低时增加SRS资源的分配，本申请实施例不作任何限定。
此外，本申请实施例所述的方式除了用于动态调整SRS资源的分配之外，也可以根据终端能力的变化动态调整其他资源的分配，本申请实施例同样不作任何限定。
