具体实施方式
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公开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、本公开的一些方面相一致的装置和方法的例子。
应当理解的是,在本文中提及的“若干个”是指一个或者多个,“多个”是指两个或两个以上。“和/或”,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。字符“/”一般表示前后关联对象是一种“或”的关系。
无线电频谱资源是一种有限、不可再生的自然资源,因此各国对于无线电频谱有专门的管理机构,出台专门的政策法规,以实现无线电频谱的统一规划管理。目前各国的频谱管理大多数采用固定频谱分配策略,即频谱资源由政府主管部门管理并分配给固定的授权用户,这样能够确保各用户之间避免过多相互干扰,更好利用频谱资源。目前频谱资源可分为两类,即授权频谱(Licensed Spectrum)和非授权频谱(Unlicensed Spectrum)。
授权频谱受到严格的限制和保护,只允许授权用户及其符合规范的设备接入,并且用户通常要为此进行付费。目前,公安、铁路、民航、广电、电信等重要的部门均拥有一定的授权频谱,这些部门内设备的通信是运行在其授权频谱上的,尤其是电信行业,我们每天使用的手机就是通过运营商拥有的授权频谱来通信的,各大运营商都拥有各自国家的无线电管理单位或部门授权的专用频段,以保障公众移动通信不受干扰。
而非授权频谱是满足一定规范和标准的设备都可以接入和使用的频谱,但必须保证不对其他用户造成干扰。比较典型的,无线保真(Wireless Fidelity,Wi-Fi)、蓝牙(Bluetooth,BT)等通信技术就是通过非授权频谱进行传输的。此外,国际通信联盟无线电通信局曾经定义过工业科学医疗(Industrial Scientific Medical,ISM)频段,主要是开放给工业、科学、医学这三类机构使用,无需授权许可,当然也需要遵守一定的发射功率,并且不能对其它频段造成干扰。
随着移动数据日益增长的通信需求,业内开展了将蜂窝移动通信技术扩展 到非授权频段的研究。比如,为了将第五代移动通信技术(Fifth-generation,5G)技术,也称新空口(new radio,NR)技术扩展到非授权频段上,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)组织通过了5G研究项目“Study on NR-based Access to Unlicensed Spectrum”(基于NR的非授权频谱接入研究),简称NR-U,旨在通过该项目的研究使NR能够满足非授权频段的法规要求,并且能够保证与工作在非授权频段上的其他接入技术和平共处。目前相关技术中并没有方案能够让终端和基站知晓二者的NR-U能力,进而做出正确的通信选择。
而本公开实施例提供的方案,可以使得终端和基站能够知晓对方对非授权频段的支持能力,进而根据对方对非授权频段的支持能力进行数据传输。比如,在5G中,通过本公开实施例提供的方案,终端和基站可以知晓二者的NR-U能力,进而做出正确的通信选择。
本公开实施例提供一种数据传输方案,可以应用于基于蜂窝移动通信技术的无线通信系统中,实现终端向基站传输上行数据。
图1是根据部分示例性实施例示出的一种无线通信系统的结构示意图,如图1所示,移动通信系统是基于蜂窝移动通信技术的通信系统,该移动通信系统可以包括:若干个终端110以及若干个基站120。
其中,终端110可以是指向用户提供语音和/或数据连通性的设备。终端110可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,终端110可以是物联网终端,如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机,例如,可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如,站(Station,STA)、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment,UE)。或者,终端110也可以是无人飞行器的设备。
基站120可以是无线通信系统中的网络侧设备。其中,该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication,4G)系统,又称长期演进(Long Term Evolution,LTE)系统;或者,该无线通信系统也 可以是5G系统,又称新空口(new radio,NR)系统。或者,该无线通信系统也可以是5G系统的再下一代系统。
其中,基站120可以是4G系统中采用的演进型基站(eNB)。或者,基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时,通常包括集中单元(central unit,CU)和至少两个分布单元(distributed unit,DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线链路层控制协议(Radio Link Control,RLC)层、媒体访问控制(Media Access Control,MAC)层的协议栈;分布单元中设置有物理(Physical,PHY)层协议栈,本公开实施例对基站120的具体实现方式不加以限定。
基站120和终端110之间可以通过无线空口建立无线连接。在不同的实施方式中,该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口;或者,该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口,比如该无线空口是新空口;或者,该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
可选的,上述无线通信系统还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中,网络管理设备130可以是无线通信系统中的核心网设备,比如,该网络管理设备130可以是演进的数据分组核心网(Evolved Packet Core,EPC)中的移动性管理实体(Mobility Management Entity,MME)。或者,该网络管理设备也可以是其它的核心网设备,比如服务网关(Serving GateWay,SGW)、公用数据网网关(Public Data Network GateWay,PGW)、策略与计费规则功能单元(Policy and Charging Rules Function,PCRF)或者归属签约用户服务器(Home Subscriber Server,HSS)等。对于网络管理设备130的实现形态,本公开实施例不做限定。
其中,上述终端与基站数据传输时,终端可以向基站上报其对非授权频谱的支持能力,以便基站根据终端对授权频谱的支持能力对终端与基站之间的数据传输进行资源调度。
比如,请参考图2,其是根据一示例性实施例示出的一种数据传输的流程示意图。如图2所示,终端与基站之间的数据传输的流程可以如下:
在步骤21中,终端向基站发送第一能力信息,该第一能力信息用于指示该终端具有基于蜂窝移动通信技术支持非授权频段的能力;基站接收该第一能 力信息。
其中,上述基于蜂窝移动通信技术支持非授权频段的能力,包括但不限于:基于蜂窝移动通信技术在非授权频段上进行数据传输的能力,以及,基于蜂窝移动通信技术在非授权频段上进行网络接入的能力中的至少一种。
终端基于蜂窝移动通信技术接入基站后,与基站之间建立无线通信连接,并通过建立的无线通信连接向基站发送第一能力信息。
可选的,该第一能力信息可以包含一个指示标识,该指示标识用于指示该终端具有基于蜂窝移动通信技术支持非授权频段的能力。
可选的,该第一能力信息中还可以包含频段指示,该频段指示用于指示该终端支持非授权频段中的哪些频段。比如,假设非授权频段有5GHz频段、37GHz频段以及60GHz频段,终端发送的第一能力信息中的频段指示可以指示该终端基于蜂窝移动通信技术支持上述非授权频段中的哪些频段。
在步骤22中,基站根据该第一能力信息生成资源调度信息,该资源调度信息用于调度该终端与该基站之间进行数据传输的资源。
在本公开实施例中,若基站也支持非授权频段,则基站对终端进行资源调度时,可以为终端对应的待传输数据分配非授权频段上的传输资源,并根据分配的传输资源生成资源调度信息。
在步骤23中,基站向该终端发送该资源调度信息;终端接收该资源调度信息。
比如,基站可以通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)向终端发送该资源调度信息。
在步骤24中,终端与基站在资源调度信息所指示的资源上进行数据传输。
在本公开实施例中,当终端支持非授权频段时,终端接入基站后,向基站上报第一能力信息,基站接收到该终端上报的第一能力信息后,可以获知该终端具有支持非授权频段的能力,后续可以根据该第一能力信息为该终端进行资源调度,从而使得基站能够知晓终端对非授权频段的支持能力,进而根据终端对非授权频段的支持能力进行资源调度并与终端进行数据传输。
图3是根据一示例性实施例示出的数据传输方法的流程图,如图3所示,该数据传输方法应用于图1所示的无线通信系统中,且由图1中的终端110执行,该方法可以包括以下步骤。
在步骤301中,向基站发送第一能力信息,该第一能力信息用于指示该终端具有基于蜂窝移动通信技术支持非授权频段的能力。
在步骤302中,接收该基站根据该第一能力信息生成并发送的资源调度信息,该资源调度信息用于调度该终端与该基站之间进行数据传输的资源。
在步骤303中,与该基站在该资源调度信息所指示的资源上进行数据传输。
可选的,该向基站发送第一能力信息之前,还包括:
获取该基站的基站能力信息,该基站能力信息用于指示该基站是否具有基于蜂窝移动通信技术支持非授权频段的能力;

可选的,该获取该基站的基站能力信息,包括:
接收该基站通过广播方式发送的该基站能力信息;
或者,

可选的,该接收该基站通过广播方式发送的该基站能力信息,包括:

此外,在本公开实施例所示的方案中,终端在接入基站之前,可以获取基站通过广播信道发送的基站能力信息,或者,之前接入基站时,基站通过单播发送的基站能力信息,并在该基站能力信息指示该基站具有基于蜂窝移动通信技术支持非授权频段的能力时接入基站,从而使得终端能够知晓基站是否具有对非授权频段的支持能力,进而根据基站是否具有对非授权频段的支持能力选择是否接入基站。
另外,在本公开实施例所示的方案中,当终端具有基于蜂窝移动通信技术支持非授权频段时,终端接入基站后,还向基站发送第二能力信息,以通知基站该终端具有支持指定接入方式的能力,基站接收到该第二能力信息后,向终端返回接入配置信息,以指示该终端后续通过该指定接入方式接入基站,从而实现了支持非授权频段的基站和终端之间的接入方式的配置。
图4是根据一示例性实施例示出的数据传输方法的流程图,如图4所示,该数据传输方法应用于图1所示的无线通信系统中,且由图1中的基站120执行,该方法可以包括以下步骤。
在步骤401中,接收终端发送的第一能力信息,该第一能力信息用于指示该终端具有基于蜂窝移动通信技术支持非授权频段的能力。
在步骤402中,根据该第一能力信息生成资源调度信息,该资源调度信息用于调度该终端与该基站之间进行数据传输的资源。
在步骤403中,将该资源调度信息发送给该终端。
在步骤404中,与该终端在该资源调度信息所指示的资源上进行数据传输。
可选的,该根据该第一能力信息生成资源调度信息,包括:

在该终端可用的频段上为该终端分配数据传输所使用的资源;
根据分配的资源生成该资源调度信息。
可选的,该接收终端发送的第一能力信息之前,还包括:
通过广播方式向该终端发送基站能力信息,该基站能力信息用于指示该基 站是否具有基于蜂窝移动通信技术支持非授权频段的能力。
可选的,该通过广播方式向该终端发送基站能力信息,包括:

根据该第二能力信息向该终端返回接入配置信息,该接入配置信息用于配置该终端后续通过该指定接入方式接入该基站。
综上所述,本公开实施例所示的方案,当终端具有基于蜂窝移动通信技术支持非授权频段的能力时,终端接入基站后,向基站上报第一能力信息,基站接收到该终端上报的第一能力信息后,可以获知该终端具有基于蜂窝移动通信技术支持非授权频段的能力,后续可以根据该第一能力信息为该终端进行资源调度,从而使得基站能够知晓终端对非授权频段的支持能力,进而根据终端对非授权频段的支持能力进行资源调度并与终端进行数据传输。
此外,在本公开实施例所示的方案中,终端在接入基站之前,可以获取基站通过广播信道发送的基站能力信息,或者,之前接入基站时,基站通过单播发送的基站能力信息,并在该基站能力信息指示该基站具有基于蜂窝移动通信技术支持非授权频段的能力时接入基站,从而使得终端能够知晓基站是否具有对非授权频段的支持能力,进而根据基站是否具有对非授权频段的支持能力选择是否接入基站。
另外,在本公开实施例所示的方案中,当终端具有基于蜂窝移动通信技术支持非授权频段时,终端接入基站后,还向基站发送第二能力信息,以通知基站该终端具有支持指定接入方式的能力,基站接收到该第二能力信息后,向终端返回接入配置信息,以指示该终端后续通过该指定接入方式接入基站,从而实现了支持非授权频段的基站和终端之间的接入方式的配置。
图5是根据一示例性实施例示出的数据传输方法的流程图,如图5所示, 该数据传输方法应用于图1所示的无线通信系统中,该方法可以包括以下步骤。
在步骤501中,终端接入基站。
在本公开实施例中,终端可以基于蜂窝移动通信技术接入基站,比如,终端检测到基站发送的同步信号并与基站进行同步后,向基站发起随机接入过程,比如,终端向基站发起基于竞争的随机接入,或者,终端向基站发起基于非竞争的随机接入过程。
可选的,终端在接入基站之前,可以获取该基站的基站能力信息,该基站能力信息用于指示该基站是否具有基于蜂窝移动通信技术支持非授权频段的能力,当该基站能力信息指示该基站具有基于蜂窝移动通信技术支持非授权频段的能力时,终端接入该基站。
在一种可能的实现方式中,当终端基于蜂窝移动通信技术只支持非授权频段时,该终端需要接入同样具有基于蜂窝移动通信技术支持非授权频段的能力的基站,可能无法接入不具有基于蜂窝移动通信技术支持非授权频段的能力的基站,该终端在接入基站之前,需要获取该基站的基站能力信息,以确定将要接入的基站是否具有基于蜂窝移动通信技术支持非授权频段的能力,若是,则向基站发起接入过程,否则不会向该基站发起接入过程。
比如,以上述蜂窝移动通信技术是5G NR技术为例,基于NR技术支持非授权频段的能力可以称为NR-U能力。当终端只具有NR-U能力,而不具有普通NR能力时,该终端可能只能接入具有NR-U能力的基站,因此,只支持NR-U能力的终端在进行网络接入时,可以获取周围各个基站的基站能力信息,并选择其中具有NR-U能力的基站进行接入。可选的,当周围具有NR-U能力的基站有多个基站时,只支持NR-U能力的终端可选根据其它因素(比如信号质量、基站支持的业务类型等等)选择其中一个基站发起接入。
或者,在另一种可能的实现方式中,当终端基于蜂窝移动通信技术同时支持非授权频段和支持授权频段时,该终端可以优先选择接入基于蜂窝移动通信技术同时支持非授权频段和支持授权频段的基站。
比如,基站的基站能力信息除了指示该基站是否具有基于蜂窝移动通信技术支持非授权频段的的能力之外,还可以指示该基站是否具有基于蜂窝移动通信技术支持授权频段的的能力。当终端基于蜂窝移动通信技术同时支持非授权频段和支持授权频段时,该终端中预先配置有接入优先级,比如,基于蜂窝移动通信技术同时支持非授权频段和支持授权频段的基站为第一优先级,基于蜂 窝移动通信技术只支持授权频段的基站为第二优先级,而基于蜂窝移动通信技术只支持非授权频段的基站为第三优先级;当终端需要接入基站时,首先获取周围各个基站的基站能力信息,并优先选择其中基于蜂窝移动通信技术同时支持非授权频段和支持授权频段的基站进行接入;当不存在基于蜂窝移动通信技术同时支持非授权频段和支持授权频段的基站,或者,向基于蜂窝移动通信技术同时支持非授权频段和支持授权频段的基站接入失败时,终端选择其中基于蜂窝移动通信技术只支持授权频段的基站进行接入;当不存在基于蜂窝移动通信技术只支持授权频段的基站,或者,向基于蜂窝移动通信技术只支持授权频段的基站接入失败时,终端才选择基于蜂窝移动通信技术只支持非授权频段的基站发起接入。
比如,以上述蜂窝移动通信技术是5G NR技术为例,基于NR技术支持非授权频段的能力可以称为NR-U能力,而基于NR技术支持授权频段的能力可以称为NR能力。同时具有NR-U能力和NR能力的终端在进行网络接入时,可以获取周围各个基站的基站能力信息,并按照预设的优先级选择基站进行接入。例如,同时具有NR-U能力和NR能力的终端检测到周围三个基站(基站1、基站2和基站3),并获取到三个基站各自的基站能力信息,其中,基站1同时具有NR-U能力和NR能力,基站2只具有NR能力,基站3只具有NR-U能力,则终端进行网络接入时,首先选择基站1进行网络接入,若向基站1接入失败,则选择基站2进行网络接入,若向基站2接入也失败,则再向基站3发起网络接入。
在一种可能的实现方式中,基站可以通过广播方式向该终端发送基站能力信息,以便该终端根据该基站的基站能力信息选择是否接入该基站。相应的,在获取该基站的基站能力信息时,终端可以接收该基站通过广播方式发送的该基站能力信息。
在本公开实施例中,基站可以通过广播方式发送系统消息,该系统消息中的主信息块MIB或者系统信息块SIB中携带该基站能力信息;相应的,在接收该基站通过广播方式发送的该基站能力信息时,终端可以接收该基站广播的系统消息,并获取该系统消息中的主信息块MIB或者系统信息块SIB中携带的该基站能力信息。
在另一种可能的实现方式中,终端可以获取本地存储的该基站能力信息;该基站能力信息是该终端之前接入该基站时,该基站通过单播无线资源控制 RRC信令发送的。
比如,当终端基于蜂窝移动通信技术同时支持非授权频段和支持授权频段时,终端在初次接入基站之前,并不知晓基站是否基于蜂窝移动通信技术支持非授权频段,但是知晓该基站基于蜂窝移动通信技术支持授权频段,此时,终端可以接入该基站,然后接收基站通过RRC信令发送的基站能力信息,并将基站发送的基站能力信息存储在本地,后续接入过程中再次检测到该基站时,可以从本地获取该基站的基站能力信息。
可选的,终端每次接入基站之后,基站通过RRC信令向终端发送基站能力信息,终端接收到基站通过RRC信令发送的基站能力信息后,若本地尚未存储该基站的基站能力信息,则直接存储该基站的基站能力信息,若本地已经存储有该基站的基站能力信息,则更新本地存储的该基站的基站能力信息。
在步骤502中,终端向基站发送第一能力信息,基站接收该第一能力信息;该第一能力信息用于指示该终端具有基于蜂窝移动通信技术支持非授权频段的能力。
在本公开实施例中,终端通过终端能力上报流程上报该第一能力信息。比如,基站可以向终端发送能力询问请求,终端接收到该能力询问请求后,向基站返回终端能力响应,该终端能力响应中包含第一能力信息。
例如,终端接入基站后,基站向终端发送终端能力询问UECapabilityEnqiry信令,终端接收到该UECapabilityEnqiry信令后,可以向基站返回终端能力信息UECapabilityInformation信令,该UECapabilityInformation信令中携带有上述第一能力信息。
在步骤503中,基站根据该第一能力信息生成资源调度信息,该资源调度信息用于调度该终端与该基站之间进行数据传输的资源。
在本公开实施例中,基站可以根据终端基于蜂窝移动通信技术支持非授权频谱的能力以及自身基于蜂窝移动通信技术支持非授权频谱的能力来对该终端进行资源配置和调度配置。
比如,在根据该第一能力信息生成资源调度信息时,基站可以根据该第一能力信息确定该终端可用的频段,该终端可用的频段中包含该终端基于蜂窝移动通信技术支持的非授权频段中的全部或者部分频段;在该终端可用的频段上为该终端分配数据传输所使用的资源;根据分配的资源生成该资源调度信息。
在本公开实施例中,基站接收到终端发送的第一能力信息,确定该终端基 于蜂窝移动通信技术支持非授权频段后,可以首先配置该终端可用的频域资源,即终端可以使用哪些频段上的资源,后续在进行数据传输调度时,再从终端可以用的频域资源中为终端调度数据传输所使用的时频资源。
比如,当终端基于蜂窝移动通信技术只支持非授权频段时,基站为终端配置的,该终端可用的频段只包含非授权频段;后续基站对终端的数据传输进行资源调度时,只为终端调度非授权频段上的时频资源。当终端基于蜂窝移动通信技术同时支持非授权频段时,基站为终端配置的,该终端可用的频段可以包括非授权频段和授权频段;后续基站对终端的数据传输进行资源调度时,既可以为终端调度非授权频段上的时频资源,也可以为为终端调度授权频段上的时频资源。
在步骤504中,基站向该终端发送该资源调度信息;终端接收该资源调度信息。
在本公开实施例中,基站可以通过物理下行控制信道PDCCH向终端发送该资源调度信息,相应的,终端过物理下行控制信道接收基站发送的该资源调度信息。
在步骤505中,终端与基站在资源调度信息所指示的资源上进行数据传输。
比如,还是以上述蜂窝移动通信技术是5G NR技术为例,当终端只具有NR-U能力时,基站为终端配置的,该终端可用的资源只包含非授权频段,后续基站为终端进行资源调度时,调度给终端使用的时频资源也只包含非授权频段上的时频资源,即终端与基站之间只在非授权频段上进行数据传输。
当终端同时具有NR-U能力和NR能力时,基站为终端配置的,该终端可用的资源同时包含非授权频段和授权频段,后续基站为终端进行资源调度时,调度给终端使用的时频资源即可以包含非授权频段上的时频资源,也可以包含授权频段上的时频资源,即终端与基站之间既可以在非授权频段上进行数据传输,也可以在授权频段上进行数据传输,或者,同时在非授权频段和授权频段上进行数据传输。
比如,针对同时支持NR-U能力的NR UE,当该UE需要高传输速率时,同样支持NR-U能力和NR能力的基站可以将非授权频段资源配置给该UE,以提高该UE的传输速率。
比如,在一种可能的应用场景中,某UE需要10Gbps的速率来支持其实时视频+文件下载业务,则基站可以将文件下载业务用NR-U传输给UE(将非 授权频段上的时频资源分配给文件下载业务对应的数据),并将实时视频业务由授权频段传输给UE(将授权频段上的时频资源分配给实时视频业务对应的数据)。或者,在另一种可能的实现方式中,基站也可以将实时视频业务用NR-U传输给UE,并将文件下载业务由授权频段传输给UE。
可选的,该终端接入基站之后,还可以向该基站发送第二能力信息,基站接收该第二能力信息,该第二能力信息用于指示该终端具有支持指定接入方式的能力,该指定接入方式是基于非授权频段的网络接入方式。基站接收到该第二能力信息后,可以向终端返回接入配置信息,该接入配置信息用于配置该终端后续通过该指定接入方式接入该基站,终端接收该接入配置信息,后续再次进行网络接入时,可以根据该接入配置信息,通过上述指定接入方式接入该基站。
其中,上述指定接入方式可以是基于蜂窝移动通信技术支持非授权频段的终端可以使用的接入技术,比如,上述指定接入方式可以包括但不限于两步随机接入。
比如,以上述蜂窝移动通信技术是5G NR技术为例,具有NR-U能力的终端接入基站之后,向基站上报其具有两步随机接入的能力,基站获取终端具有两步随机接入的能力后,可以将进行两步随机接入所需要的配置告知该终端,下次该终端进行接入时,可以根据基站通知的配置,使用两步随机接入方式来接入该基站。
综上所述,本公开实施例所示的方案,当终端具有基于蜂窝移动通信技术支持非授权频段的能力时,终端接入基站后,向基站上报第一能力信息,基站接收到该终端上报的第一能力信息后,可以获知该终端具有基于蜂窝移动通信技术支持非授权频段的能力,后续可以根据该第一能力信息为该终端进行资源调度,从而使得基站能够知晓终端对非授权频段的支持能力,进而根据终端对非授权频段的支持能力进行资源调度并与终端进行数据传输。
此外,在本公开实施例所示的方案中,终端在接入基站之前,可以获取基站通过广播信道发送的基站能力信息,或者,之前接入基站时,基站通过单播发送的基站能力信息,并在该基站能力信息指示该基站具有基于蜂窝移动通信技术支持非授权频段的能力时接入基站,从而使得终端能够知晓基站是否具有对非授权频段的支持能力,进而根据基站是否具有对非授权频段的支持能力选择是否接入基站。
另外,在本公开实施例所示的方案中,当终端具有基于蜂窝移动通信技术支持非授权频段时,终端接入基站后,还向基站发送第二能力信息,以通知基站该终端具有支持指定接入方式的能力,基站接收到该第二能力信息后,向终端返回接入配置信息,以指示该终端后续通过该指定接入方式接入基站,从而实现了支持非授权频段的基站和终端之间的接入方式的配置。
