具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、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)系统、先进的长期演进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、NR-U系统、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、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type Communication,MTC),以及车辆间(Vehicle to Vehicle,V2V)通信等,本申请实施例也可以应用于这些通信系统。
示例性的,本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110,网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备进行通信。可选地,该网络设备110可以是GSM系统或CDMA系统中的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的网络设备等。

可选地,终端设备120之间可以进行终端直连(Device to Device,D2D)通信。
可选地,5G系统或5G网络还可以称为新无线(New Radio,NR)系统或NR网络。
图1示例性地示出了一个网络设备和两个终端设备,可选地,该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。
可选地,该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体,本申请实施例对此不作限定。
应理解,本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例,通信设备可包括具有通信功能的网络设备110和终端设备120,网络设备110和终端设备120可以为上文所述的具体设备,此处不再赘述;通信设备还可包括通信系统100中的其他设备,例如网络控制器、移动管理实体等其他网络实体,本申请实施例中对此不做限定。
应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
本申请实施例的方法可以应用于非授权频谱(或者说共享频谱)的通信中,也可以应用于其它通信场景中,本申请对此不作具体限定。
非授权频谱是国家和地区划分的可用于无线电设备通信的频谱,该频谱可以被认为是共享频谱,即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求,就可以使用该频谱,可以不向政府申请专有的频谱授权。
为了让使用非授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存,通信设备在非授权频谱上进行通信时,可以遵循先听后说(Listen Before Talk,LBT)的原则,即,通信设备在非授权频谱的信道上进行信号发送前,需要先进行信道侦听(或称为信道检测),只有当信道侦听结果为信道空闲时,通信设备才能进行信号发送;如果通信设备在非授权频谱的上进行信道侦听的结果为信道忙,则不能进行信号发送。可选地,LBT的带宽是20MHz,或为20MHz的整数倍。
为了更加清楚地理解本申请,以下将对非授权频谱通信中所应用的概念进行阐述。
最大信道占用时间(Maximum Channel Occupancy Time,MCOT),可以是指LBT成功后允许使用非授权频谱的信道进行信号传输的最大时间长度,不同信道接入方案下有不同的MCOT。MCOT的最大取值例如可以为10ms。应理解,该MCOT为信号传输占用的时间。
信道占用时间(Channel Occupancy Time,COT),可以是指LBT成功后使用非授权频谱的信道进行信号传输的时间长度,该时间长度内信号占用信道可以是不连续的。其中,一次COT最长不可以超过例如20ms,该COT内的信号传输占用的时间长度不超过MCOT。
基站的信道占用时间(gNB-initiated COT),也可以称为基站发起的COT,指基站LBT成功后获得的一次信道占用时间。基站的信道占用时间内除了可以用于下行传输,也可以在满足一定条件下用于UE进行上行传输。
UE的信道占用时间(UE-initiated COT),也可以称为UE发起的COT,指UE LBT成功后获得的一次信道占用时间。
下行(Downlink,DL)传输机会(DL burst),基站进行的一组下行传输(即包括一个或多个下行传输),该组下行传输为连续传输(即多个下行传输之间没有空隙),或该组下行传输中有空隙但空隙小于或等于特定时长(例如,16μs)。如果基站进行的两个下行传输之间的空隙大于该特定时长(例如,16μs),那么可以认为该两个下行传输属于两次下行传输机会。
上行(Uplink,UL)传输机会(UL burst),一个UE进行的一组上行传输(即包括一个或多个上行传输),该组上行传输为连续传输(即多个上行传输之间没有空隙),或该组上行传输中有空隙但空隙小于或等于特定时长(例如,16μs)。如果该UE进行的两个上行传输之间的空隙大于该特定时长(例 如,16μs),那么可以认为该两个上行传输属于两次上行传输机会。
在本申请实施例中,通信设备可以采用相应的信道接入方案进行LBT操作。为了便于理解,以下介绍几种信道接入方案。
通信设备获得信道占用的模式可以是基于负载的设备(Load Based Equipment,LBE)的信道接入模式,即通信设备可以在业务到达后进行共享信道上的LBT,并在LBT成功后在该共享信道上开始传输;也可以是基于帧结构的设备(Frame Based Equipment,FBE)的信道接入模式,即通信设备周期性地进行共享信道上的LBT。其中,FBE信道接入模式也可以被称为是半静态信道接入模式。
其中,LBE信道接入模式下可以包括多种不同的信道接入方案。
(1)、类型(Type)1信道接入:
通信设备的信道检测方式为基于竞争窗口大小调整的随机回退的多时隙信道检测。具体地,在Type1信道接入下,根据传输业务的优先级可以包括不同的信道接入优先级(Channel Access Priority Class,CAPC)。表1和表2分别为不同信道接入优先级对应的信道接入参数的两个示例。可选地,表1用于网络设备的Type1信道接入,表2用于终端设备的Type1信道接入。其中,p取值越小(或者说CAPC取值越小),信道接入优先级越高。
表1
Figure PCTCN2019130654-appb-000001
表2
Figure PCTCN2019130654-appb-000002
其中,在上述表1或表2中,m p是指信道接入优先级对应的回退时隙个数,CWp是指信道接入优先级对应的竞争窗口大小,CWmin,p是指信道接入优先级对应的CWp取值的最小值,CWmax,p是指信道接入优先级对应的CWp取值的最大值,Tmcot,p是指信道接入优先级对应的信道最大占用时间长度。
(2)、Type2A信道接入:
通信设备的信道检测方式为25微秒的单时隙信道检测。具体地,Type2A信道接入下,通信设备在传输开始前可以进行25微秒的信道检测,并在信道检测成功后进行传输。
(3)、Type2B信道接入:
通信设备的信道检测方式为16微秒的单时隙信道检测。具体地,Type2B信道接入下,通信设备在传输开始前可以进行16微秒的信道检测,并在信道检测成功后进行传输。可选地,该传输的起始位置距离上一次传输的结束位置之间的空隙大小为16微秒。
(4)、Type2C信道接入:
通信设备在空隙结束后不做信道检测而进行传输。具体地,Type2C信道接入下,通信设备可以直接进行传输,其中,该传输的起始位置距离上一次传输的结束位置之间的空隙大小为小于或等于16微秒。可选地,使用Type2C信道接入下的该传输的长度不超过584微秒。
不同传输场景下应用的信道接入方案不同,不同信号或信道应用的信道接入方案也不同。当网络设备发起COT后,可以将该COT内的资源用于UE进行上行传输。
对于基于FBE的信道接入方式,如图2所示,在该方式中,帧结构是周期出现的,在一个帧结构内包括固定帧周期(长度不超过预设值例如10ms)、信道占用时间(长度不超过固定帧周期的95%)、空闲时间(长度至少为信道占用时间的5%,最小值为100us,且位于固定帧周期的尾部)。网络设备在空隙时间内对共享信道做LBT(例如可以是单时隙信道检测,或者说单时隙空闲信道评估(Clear Channel Assessment,CCA)),如果LBT成功,下一个固定帧周期内的信道占用时间可以用于传输信号;如果LBT失败,下一个固定帧周期内的信道占用时间不能用于传输信号。或者说,通信设备可以用于业务发送的信道资源是周期性出现的。
在NR-U系统中,当终端设备被调度进行PUSCH或PUCCH的传输时,网络设备可以通过携带UL授权或DL授权的DCI指示该PUSCH或PUCCH对应的信道接入方案。具体的信道接入方案的指示如下所示。
(1)、调度PUSCH传输的非回退上行授权(例如DCI格式0_1):
①、高层参数配置第一指示集合,第一指示集合中包括至少一项联合编码的信道接入类型,扩展循环前缀(Extended Cyclic Prefix,ECP)长度和CAPC。
②、该非回退上行授权中包括第一指示信息,该第一指示信息用于从上述第一指示集合中确定联合编码的信道接入类型,ECP长度和CAPC。
③、该信道接入类型,ECP长度和CAPC用于PUSCH传输。
④、第一指示信息最多包括6比特。
(2)、调度PDSCH传输的非回退下行授权(例如DCI格式1_1):

②、该非回退下行授权中包括第二指示信息,该第二指示信息用于从上述第二指示集合中确定联合编码的信道接入类型和ECP长度。
③、该信道接入类型和ECP长度用于PUCCH传输,其中,该PUCCH可以承载PDSCH对应的混合自动重传请求-确认应答(Hybrid Automatic Repeat reQuest-Acknowledgement,HARQ-ACK)信息。可选地,CAPC=1。
④、第二指示信息最多包括4比特。
(3)、调度PUSCH传输的回退上行授权(例如DCI格式0_0):
①、该回退上行授权中包括第三指示信息,该第三指示信息用于从第三指示集合中确定联合编码的信道接入类型和ECP长度。
②、第三指示集合是预设的,如下表3所示。
③、该信道接入类型和ECP长度用于PUSCH传输。可选地,终端设备自行选择CAPC,例如终端设备根据上行信道中承载的业务的优先级自行选择CAPC。
④、第三指示信息包括2比特。
(4)、调度PDSCH传输的回退下行授权(例如DCI格式1_0):
①、该回退下行授权中包括第四指示信息,该第四指示信息用于从第三指示集合中确定联合编码的信道接入类型和ECP长度。
②、第三指示集合是预设的,如下表3所示。
③、该信道接入类型和ECP长度用于PUCCH传输,其中,该PUCCH可以承载PDSCH对应的HARQ-ACK信息。可选地,CAPC=1。
④、第四指示信息包括2比特。
表3
指示信息 信道接入类型 ECP长度
0 Type2C信道接入 C2*符号长度-16us-TA
1 Type2A信道接入 C3*符号长度-25us-TA
2 Type2A信道接入 C1*符号长度-25us
3 Type1信道接入 0
其中,C2和C3的取值是预设的或高层参数配置的,C1的取值是预设的。
另外,当终端设备收到网络设备发送的UL授权或DL授权指示该PUSCH或PUCCH对应的信道接入类型为Type1信道接入时,如果终端设备能确定该PUSCH或PUCCH属于网络设备的信道占用时间内,例如终端设备收到网络设备发送的DCI格式2_0,并根据该DCI格式2_0确定该PUSCH或PUCCH属于网络设备的信道占用时间内,那么终端设备可以确定该PUSCH或PUCCH对应的信道接入类型为Type2A信道接入而不再是Type1信道接入。
若终端设备需要在一个DCI调度下在共享信道上传输至少两个上行信道时,如何确定这至少两个信道的信道接入参数。
因此,本申请实施例提供了以下的方案,可以确定至少两个信道在一个DCI调度下在共享信道上的信道接入参数,从而可以保证共享信道上的资源公平共享。
下面结合图3,对本申请实施例提供的方案进行详细说明。
如图3所示,为本申请一实施例提供的无线通信方法300的示意性流程图。该无线通信方法300可以包括步骤310-320。
310,终端设备接收网络设备发送的第一指示信息,所述第一指示信息指示第一信道接入参数,所述第一信道接入参数用于传输第一上行信道,所述第一指示信息为第一DCI中承载的信息,所述第一DCI用于确定所述第一上行信道和第二上行信道的传输。
本申请实施例中的第一信道接入参数用于传输第一上行信道,可以是指利用第一信道接入参数进行信道检测。在一种方式下,若基于第一信道接入参数进行信道检测成功,则终端设备可以确定第一信道接入参数用于传输第一上行信道;若基于第一信道接入参数进行信道检测失败,则终端设备确定不能基于第一信道接入参数传输第一上行信道。
本申请实施例中,终端设备接收网络设备发送的第一指示信息可以为第一DCI中承载的信息,从而终端设备可以基于该第一指示信息确定第一上行信道和第二上行信道的传输。
320,所述终端设备确定所述第一信道接入参数中的至少部分信道接入参数用于传输第二上行信道;或所述终端设备确定第二信道接入参数用于传输所述第二上行信道;或所述终端设备确定不传输所述第二上行信道。
本申请实施例中的第二上行信道可以包括PUSCH、PUCCH或物理随机接入信道(Physical Random Access Channel,PRACH)等。从而,终端设备可以确定第一信道接入参数中的至少部分信道接入参数或第二信道接入参数用于传输PUSCH、PUCCH或PRACH的一种信道,或确定不传输PUSCH、PUCCH或PRACH。
应理解,在一些实现方式下,本申请实施例中的第二上行信道也可以为第二上行信号,该上行信号可以包括信道探测参考信号(Sounding Reference Signal,SRS)或信道状态信息(Channel State Information,CSI)。
还应理解,本申请实施例中,在一个DCI调度在共享信道上的多个信道(大于两个信道)的情况下,终端设备也可以确定第一上行信道中的至少部分信道接入参数或第二信道接入参数传输这多个信道,或不传输这多个信道。
本申请实施例中,在第一指示信息指示的第一信道接入参数用于传输第一上行信道的情况下,终端设备可以确定用于传输第二上行信道的信道接入参数为该第一信道接入参数中的部分信道接入参数或第二信道接入参数或可以不确定用于传输第二上行信道的信道接入参数。
本申请实施例中,终端设备在确定不用第一信道接入参数中的至少部分接入参数或第二信道接入参数传输第二上行信道的情况下,终端设备也可以采用其它方式传输第二上行信道。
在一些实现方式中,网络设备也可以向终端设备发送一个指示信息,该指示信息可以用于指示终端设备采用第一信道接入参数中的至少部分信道接入参数或第二信道接入参数传输第二上行信道或不传输第二上行信道。
本申请实施例提供的无线通信方法,若一个DCI调度在共享信道上的至少两个信道,终端设备可以确定第一上行信道中的至少部分信道接入参数或第二信道接入参数传输第二上行信道,或确定不传输第二上行信道,从而可以保证共享信道上的资源公平共享。
上文指出,终端设备接收到的第一指示信息指示的第一信道接入参数可以用于传输第二上行信道。下文将具体描述第一信道接入参数所包括的参数。
可选地,在一些实施例中,所述第一指示信息指示第一信道接入参数,包括以下情况中的一种:所述第一指示信息指示第一信道接入类型、第一ECP长度和第一CAPC;所述第一指示信息指示第一信道接入类型和第一ECP长度。
本申请实施例中的第一信道接入类型可以为Type1信道接入、Type2A信道接入、Type2B信道接入、Type2C信道接入中的一种。
在一些实现方式下,若终端设备接收到网络设备发送的上行授权信息,该上行授权信息中可以包括本申请实施例中的第一指示信息,该第一指示信息所指示的第一信道接入参数可以包括第一信道接入类型、第一ECP长度以及第一CAPC;若终端设备接收到网络设备发送的下行授权信息,该下行授权信息中可以包括本申请实施例中的第一指示信息,该第一指示信息所指示的第一信道接入参数可以包括第一信道接入类型和第一ECP长度。
可选地,在一些实施例中,所述第一信道接入参数包括第一信道接入类型、第一ECP长度和第一CAPC中的至少一项,所述终端设备根据所述第一信道接入参数中的至少部分接入参数传输第二上行信道,包括:所述终端设备根据所述第一信道接入类型、所述第一ECP长度和所述第一CAPC中的至少一项传输所述第二上行信道。
本申请实施例中,若第一信道接入参数包括第一信道接入类型、第一ECP长度和第一CAPC中的至少一项,终端设备可以根据第一信道接入类型、第一ECP长度和第一CAPC中的至少一项传输第二上行信道。
换句话说,终端设备可以根据第一信道接入类型、第一ECP长度和第一CAPC中的一项传输第二上行信道;终端设备也可以根据第一信道接入类型和第一ECP长度传输第二上行信道;终端设备还可以根据第一信道接入类型第一ECP长度和第一CAPC传输第二上行信道。
以第一上行信道为第一PUSCH,第二上行信道为第一SRS为例。本申请实施例中,若终端设备接收到DCI格式0_1传输的上行授权信息,该上行授权信息可以用于调度第一PUSCH的传输,并可以触发非周期的第一SRS传输,该授权信息中可以包括第一指示信息,该第一指示信息可以用于从第一指示集合中确定第一上行信道的第一信道接入参数。其中,该第一信道接入参数可以用于传输第一上行信道,该第一信道接入参数可以包括第一信道接入类型、第一ECP长度以及第一CAPC。
若第一PUSCH和第一SRS属于不同的上行传输机会,则终端设备可以基于第一信道接入参数中的至少部分接入参数传输第一SRS。
具体地,例如,在一种实现方式下,终端设备可以基于第一信道接入参数中的第一信道接入类型传输第一SRS。若第一信道接入参数中的第一信道接入类型为Type1信道接入,则终端设备可以基于Type1信道接入传输第一SRS;若第一信道接入参数中的第一信道接入类型为Type2A信道接入,则终端设备可以基于Type2A信道接入传输第一SRS;若第一信道接入参数中的第一信道接入类型为Type2B信道接入,则终端设备可以基于Type2B信道接入传输第一SRS;若第一信道接入参数中的第一信道接入类型为Type2C信道接入,则终端设备可以基于Type2C信道接入传输第一SRS。
在另一种实现方式下,终端设备可以基于第一信道接入参数中的第一信道接入类型和第一ECP长度传输第一SRS。若第一信道接入参数中的第一信道接入类型为Type1信道接入且第一ECP长度为0,则终端设备可以基于信道接入类型为Type1信道接入且ECP长度为0的ECP长度传输第一SRS;若第一信道接入参数中的第一信道接入类型为Type2A信道接入且第一ECP长度为a,则终端设备可以基于信道接入类型为Type2A信道接入且ECP长度为a的ECP长度传输第一SRS,其中,该第一ECP长度可以根据上述表3确定;若第一信道接入参数中的第一信道接入类型为Type2B信道接入且第一ECP长度为b,则终端设备可以基于信道接入类型为Type2B信道接入且ECP长度为b的ECP长度传输第一SRS,其中,该第一ECP长度也可以根据上述表3确定;若第一信道接入参数中的第一信道接入类型为Type2C信道接入且第一ECP长度为c,则终端设备可以基于信道接入类型为Type2C信道接入且ECP长度为c的ECP长度传输第一SRS,同样地,该第一ECP长度也可以根据上述表3确定。
在又一种实现方式下,终端设备可以基于第一信道接入参数中的第一ECP长度传输第一SRS。若第一信道接入参数中的第一ECP长度为0,则终端设备可以基于ECP长度为0的ECP长度传输第一SRS。

同样地,以第一上行信道为第一PUSCH,第二上行信道为第一SRS为例。若终端设备确定根据第一信道接入类型和/或第一ECP长度确定传输第一SRS,则终端设备可以基于值为1的CAPC传输第一SRS;或者终端设备可以自行选择传输第一SRS的CAPC值,例如,可以选择值为1或2或3或4的CAPC传输第一SRS,本申请对此不作具体限定。

本申请实施例中,第一上行信道可以为第一PUSCH或第一PUCCH,第二上行信道可以为第二PUSCH或第二PUCCH或SRS。
在第一DCI位下行授权的情况下,第一上行信道可以包括第一PUCCH,第二上行信道可以包括SRS。本申请实施例中的第一DCI可以用于调度第一PDSCH的传输,而第一PDSCH是通过第一PUCCH中传输的,因此,本申请实施例中的第一信道接入参数用于传输第一PUCCH,从而可以基于第一DCI调度第一PDSCH。
类似地,对于第一上行信道为第一PUSCH,第二上行信道为SRS,或第一上行信道为第一PUSCH,第二上行信道为第二PUSCH,可以参见前述内容,为了简洁,这里不再赘述。
本申请实施例也可以应用确定随机接入过程中的共享信道上的信道接入参数。随机接入过程可以包括4步随机接入过程和2步随机接入过程。其中,如图5a所示,对于4步随机接入过程可以包括步骤511-514。
511,UE向基站发送随机接入前导序列(也可以称为消息1(message 1,MSG1))。
512,基站检测到有UE发送接入前导序列之后向UE发送随机接入响应(Random Access Preamble,RAR)(也即message 2,MSG2)以告知UE在发送MSG3(message 3)可以使用的上行资源信息,为UE分配临时无线网络临时标识(Radio Network Temporary Identity,RNTI),给UE提供定时提前命令(Timing Advance Command,TAC)等,如果UE在RAR窗内没有检测到RAR,UE进行PRACH序列的重传,如果UE在RAR窗内检测到RAR,UE可以根据RAR指示的上行授权进行MSG3的传输。
513,UE接收到随机接入响应RAR之后,在随机接入响应消息所指定的上行资源中发送MSG3消息,该步骤允许HARQ重传;
514,基站向UE发送MSG4消息,其中包括竞争解决消息,同时为UE分配上行传输资源,该步骤允许HARQ重传。UE接收到基站发送的MSG4时,会检测MSG4中是否包括UE发送的MSG3消息中的部分内容。若包括则表明UE随机接入过程成功,否则认为随机过程失败,UE可以再次从第一步开始发起随机接入过程。
4步随机接入过程的时延较大,对于5G中的低时延高可靠场景是不合适的。在NR的标准化过程中,提出2步RACH过程的方案,相比4步RACH过程,可以减少接入时延。2步RACH过程如图5b所示,该过程可以步骤521-522。
521,UE向基站发送带有其它信息的随机接入前导序列。
522,UE接收基站发送的带有冲突解决消息的RAR。
简单的说,相当于将4步RACH过程的第一步和第三步合并为两步RACH过程中的第一步(消 息A,MSGA),将四步RACH过程的第二步和第四步合并为两步RACH过程中的第二步(消息B,MSGB)。其中,在两步RACH中的第一步中,UE需要发送前导码和PUSCH,即MSGA包括前导码和PUSCH。
若终端设备需要在一个随机接入过程中传输前导码和PUSCH时,如何确定传输前导码和PUSCH这至少两个信道的信道接入参数。
因此,本申请实施例提供了以下的方案,可以确定至少两个信道在一个随机接入过程中的信道接入参数,从而可以保证共享信道上的资源公平共享。
如图6所示,为本申请另一实施例提供的无线通信方法600的示意性图。该方法600可以包括步骤610-620。
