无线通信的方法和装置

技术领域
本发明实施例涉及通信领域，并且更具体地，涉及无线通信的方法和装置。
背景技术
在某些通信系统(例如，早期部署的通信系统)中，由于接入网络设备(例如，基站)的终端设备的个数相对较少，且用户对业务访问(例如，数据传输速率要求或数据传输时延)的要求相对较低，因此，网络设备的配置优先考虑提供的网络(为了便于理解和区分，记做第一网络)的覆盖范围，即，希望尽可能扩大第一网络的覆盖范围，以使得该更加广阔的覆盖范围内的用户可以通过同一个网络设备接入到该网络，从而降低部署和运营的成本。
随着移动通信的普及和发展，用户数量不断增加，尤其在一些高密集人群聚集区，例如，大型比赛场地、车站、机场等，需要在相对较小的范围内容纳更多用户的接入，导致第一网络的网络设备很容易出现如过载等无法提供正常服务的现象，严重影响了用户体验。
为了改善用户体验，可以在该第一网络的覆盖范围内，设置能够提供覆盖范围较小的网络(为了便于理解和区分，记做第二网络)的网络设备，以使第一网络内的终端设备通过该第二网络传输数据，进而减少第一网络的网络设备的负担。
但是，由于第二网络覆盖范围较小，受终端设备的移动和下行信道质量等限制，可能导致终端设备无法接收到第二网络的网络设备所发送的数据的情况，影响了用户体验。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
在本说明书中使用的术语“部件”、“模块”、“系统”等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如，部件可以是但不限于，在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。通过图示，在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程或执行线程中，部件可位于一个计算机上和/或分布在2个或更多个计算机之间。此外，这些部件可在上面存储有各种数据结构的各种计算机可读介质上执行。其中，“部件”可以根据例如，具有一个或多个数据分组的信号通过本地或远程进程来通信，并且，数据分组可以是，例如，来自与本地系统、分布式系统或网络间的另一部件交互的二个部件的数据。
本发明实施例的方案可以应用于现有的蜂窝通信系统，如全球移动通讯(英文全称可以为：Global System for Mobile Communication，英文简称可以为：GSM)，宽带码分多址(英文全称可以为：Wideband Code Division Multiple Access，英文简称可以为：WCDMA)，长期演进(英文全称可以为：Long Term Evolution，英文简称可以为：LTE)等系统中，所支持的通信主要是针对语音和数据通信的。通常来说，一个传统基站支持的连接数有限，也易于实现。
下一代移动通信系统将不仅支持传统的通信，还将支持机器到机器(英文全称可以为：Machine to Machine，英文简称可以为：M2M)通信，或者 叫做机器类型通信(英文全称可以为：Machine Type Communication，英文简称可以为：MTC)通信。根据预测，到2020年，连接在网络上的MTC设备将会达到500到1000亿，这将远超现在的连接数。对M2M类业务，由于其业务种类千差万别，对网络需求存在很大差异。大致来说，会存在如下几种需求：
可靠传输，但对时延不敏感；
低延迟，高可靠传输。
对可靠传输，但对时延不敏感业务，较容易处理。但是，对低延迟、高可靠传输类的业务，不仅要求传输时延短，而且要求可靠，比如设备到设备(英文全称为：Device to Device，英文简称可以为：D2D)业务。如果传输不可靠，会导致重传而造成传输时延过大，不能满足要求。
由于大量连接的存在，使得未来的无线通信系统和现有的通信系统存在很大差异。大量连接需要消耗更多的资源接入终端设备以及需要消耗更多的资源用于终端设备的数据传输相关的调度信令的传输。根据本发明实施例的方案能够有效解决上述资源消耗问题。
可选地，该网络设备为基站，该终端设备为用户设备。
本发明结合终端设备描述了各个实施例。终端设备也可以称为用户设备(英文全称为：User Equipment，英文简称可以为：UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备可以是无线局域网(英文全称为：Wireless Local Area Networks，英文简称可以为：WLAN)中的站点(英文全称为：STATION，英文简称可以为：ST)，可以是蜂窝电话、无绳电话、会话启动协议(英文全称为：Session Initiation Protocol，英文简称可以为：SIP)电话、无线本地环路(英文全称为：Wireless Local Loop，英文简称可以为：WLL)站、个人数字处理(英文全称为：Personal Digital Assistant，英文简称可以为：PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及未来5G网络中的终端设备或者未来演进的公共陆地移动网络(英文全称为：Public Land Mobile Network，英文简称可以为：PLMN)网络中的终端设备等。
此外，本发明结合网络设备描述了各个实施例。网络设备可以是网络设 备等用于与移动设备通信的设备，网络设备可以是WLAN中的接入点(英文全称为：Access Point，英文简称可以为：AP)，GSM或码分多址CDMA(英文全称为：Code Division Multiple Access，英文简称可以为：CDMA)中的基站(英文全称为：Base Transceiver Station，英文简称可以为：BTS)，也可以是WCDMA中的基站(英文全称为：NodeB，英文简称可以为：NB)，还可以是LTE中的或演进型基站(英文全称为：Evolutional Node B，英文简称可以为：eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及未来5G网络中的终端设备或者未来演进的PLMN网络中的网络设备等。
此外，本发明实施例的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘，例如，压缩盘(英文全称为：Compact Disk，英文简称可以为：CD)、数字通用盘(英文全称为：Digital Versatile Disk，英文简称可以为：DVD)等，智能卡和闪存器件，例如，可擦写可编程只读存储(英文全称为：Erasable Programmable Read-Only Memory，英文简称可以为：EPROM)器、卡、棒或钥匙驱动器等。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
图1是适用本发明实施例的无线通信的方法的通信系统的示意图。如图1所示，该通信系统100包括网络设备102(即，第一网络设备的一例)，网络设备104(即，第二网络设备的一例)和终端设备106。
其中，网络设备(例如，网络设备102或终端设备106)可包括多个天线。另外，网络设备可附加地包括发射机和接收机，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
网络设备可以与一个或多个终端设备(例如，终端设备106)通信。然而，可以理解，网络设备可以与类似于终端设备的任意数目的终端设备通信。终端设备可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信 系统100上通信的任意其它适合设备。
并且，网络设备通过前向链路向终端设备发送信息，并通过反向链路从终端设备接收信息。
例如，在频分双工(英文全称为：Frequency Division Duplex，英文简称可以为：FDD)系统中，例如，前向链路可利用与反向链路所使用的不同频带。
再例如，在时分双工(英文全称为：Time Division Duplex，英文简称可以为：TDD)系统和全双工(英文全称为：Full Duplex)系统中，前向链路和反向链路可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为网络设备的扇区。例如，可将天线组设计为与网络设备覆盖区域的扇区中的终端设备通信。在网络设备通过前向链路1分别与终端设备进行通信的过程中，网络设备的发射天线可利用波束成形来改善前向链路的信噪比。此外，与网络设备通过单个天线向它所有的终端设备发送信号的方式相比，在网络设备利用波束成形向相关覆盖区域中随机分散的终端设备发送信号时，相邻小区中的移动设备会受到较少的干扰。
在给定时间，网络设备或终端设备可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。具体地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
在本发明实施例中，第一网络设备(例如，网络设备102)与第二网络设备(例如，网络设备104)使用不同的无线接入技术与终端设备进行通信。
无线接入技术(英文全称为：Radio Access Technology，英文简称可以为：RAT)也称空中接口技术，是实现无线通信的关键。它是指通过无线介质将终端设备与网络设备连接起来，以实现用户与网络间的信息传递。无线信道传输的信号应遵循一定的协议，这些协议即构成无线接入技术的主要内容。无线接入技术与有线接入技术的一个重要区别在于可以向用户提供移动接入业务。无线接入网是指部分或全部采用无线电波这一传输媒质连接用户与交换中心的一种接入技术。在通信网中，无线接入系统的定位是本地通信 网的一部分，是本地有线通信网的延伸、补充和临时应急系统。
无线接入技术决定了无线通信的特性，例如，延迟、传输速率或覆盖范围等。
在本发明实施例中，不同的RAT可以是以下至少一种参数或信息相异的RAT：
波形参数、调制方式、多址方式、带宽配置、无线帧配置方式、资源复用方式、用户调度方式、信道配置方式、编码方式或协议栈配置方式。
下面分别对上述各参数的具体功能和定义进行详细说明。
A.波形参数
波形参数，或者说波形的参数，是指能够指示或者说决定一种波形的参数。
作为实例而非限定，在本发明实施例中，该波形参数可以包括以下至少一种参数：

A2.单载波频分多址(SC-OFDM，Single-carrier Frequency-Division Multiple Access)中使用的波形参数；

在本发明实施例中，该目标无线资源可以是网络设备#A从第二网络设备分配或授权的无线资源中确定的(即，方式1)，或者，该目标无线资源也可以是网络设备#B确定的(即，方式2)，下面，分别对上述两种方式下的具体处理过程进行详细说明。
方式1
可选地，当该目标数据包括该无线资源指示信息时，该第一网络设备进行与第二网络设备之间的协商处理，包括：
该第一网络设备接收该第二网络设备发送的用于指示该第二网络设备分配或授权的无线资源的第一指示信息；
该第一网络设备根据该第一指示信息，从该第二网络设备分配或授权的无线资源中，确定该目标无线资源；

具体地说，在本发明实施例中，第一网络设备和上述备选的网络设备之间(例如，网络设备#A和网络设备#B之间)可以设置有通信连接，例如，通过光纤、铜线或无线链路等实现的通信连接。
从而，网络设备#B可以将用于指示网络设备#B分配或授权的无线资源的第一指示信息发送给网络设备#A。

应理解，以上列举的网络设备#A确定网络设备#B分配或授权的无线资源的方法仅为示例性说明本发明并未限定于此，例如，网络管理员可以预先在网络设备#A中存储用于指示网络设备#B分配或授权的无线资源的指示信 息，或者，网络设备#A也可以预先从该网络设备#B的管理设备(或者说，高层设备)获取用于指示网络设备#B分配或授权的无线资源的指示信息。
从而，网络设备#A可以从网络设备#B分配或授权的无线资源中，确定目标无线资源。
例如，网络设备#A可以预先获知终端设备需要发送的上行数据的数据量和该上行数据的传输要求(或者说，该上行数据所属于的业务的业务要求，例如，传输间隔或时延等)，并根据该上行数据的数据量，确定目标无线资源，以使该目标无线资源能够满足上行数据的传输要求。
其后，网络设备#A可以使用第一RAT所对应的协议栈(例如，上述协议栈#A)对该目标无线资源的指示信息进行封装处理，以生成符合第一RAT的传输要求的第一指示信息，并将该第一指示信息发送给终端设备。
从而，终端设备可以根据第一RAT所对应的协议栈(例如，上述协议栈#A’)，对该第一指示信息进行解封装处理，以获取该目标无线资源的指示信息，进而确定该目标无线资源。
方式2

网络设备#A可以预先获知终端设备需要发送的上行数据的数据量，并将指示该上行数据的数据量的信息(即，第二指示信息的一例)发送给网络设备#B。
从而，网络设备#B可以根据该上行数据的数据量，从系统分配给该网络设备#B的无线资源中，确定目标无线资源，以使该目标无线资源能够满足上行数据的传输要求。
应理解，以上列举的网络设备#B确定目标无线资源的方法仅为示例性说明，本发明并未限定于此，例如，网络设备#A还可以告知网络设备#B该上行数据所属于的业务的业务要求，例如，传输间隔或时延等，并且，网络设备#B可以根据上行数据的数量和该业务要求，确定目标无线资源，以使该目标无线资源能够满足该上行数据所属于的业务的业务要求。

其后，网络设备#A可以通过协议栈#A的全部或部分协议层对该目标无线资源的指示信息(即，第三指示信息)进行封装处理，以生成符合第一RAT的传输要求的第三指示信息，并将该第一指示信息发送给终端设备。
需要说明的是，在本发明实施例中，第三指示信息也可以是未经过设置在网络设备#B中的协议栈#B封装处理后的信息，从而，终端设备仅需要通过协议栈#A’对第一指示信息进行解封装处理，便能够获取该第三指示信息，进而确定目标无线资源。
或者，该第三指示信息也可以是网络设备#B通过协议栈#B的全部或部分协议层封装处理后的信息。即，终端设备需要通过协议栈#A’的全部或部分协议层对第一指示信息进行解封装处理，以获取该第三指示信息，并通过协议栈#B’的全部或部分协议层，对该进行解封装处理，以获取第三指示信息的内容，进而确定目标无线资源。随后，对上述过程进行详细说明。
在本发明实施例中，终端设备除上述第一RAT和第二RAT以外，可能还支持其他RAT，此情况下，网络设备#A还需要通知终端设备该网络设备#B所使用的RAT类型，即，网络设备#A还可以通过第一RAT，向终端设备发送第二RAT的RAT类型的指示信息，从而，终端设备可以根据第二RAT的RAT类型的指示信息，启用与该第二RAT相对应的协议栈#B’来封装需要发送给网络设备#B的上行数据，或者解析网络设备#B通过协议栈#B封装的目标无线资源的指示信息。
例如，网络设备#A可以通过协议栈#A，对第二RAT的RAT类型的指示信息进行封装处理，以生成符合第一RAT的传输要求的RAT类型指示信息，并将该RAT类型指示信息发送给终端设备。
从而，终端设备可以根据协议栈#A’，对该RAT类型指示信息进行解封装处理，以获取该第二RAT的RAT类型的指示信息，进而确定发送上行数据时使用的RAT类型(即，第二RAT)。
如上所述，终端设备能够确定用于通过第二RAT传输上行数据时使用的目标无线资源。
从而，终端设备可以通过协议栈#B’对上行数据进行封装处理，以生成符合第二RAT规定的数据，并通过该目标无线资源，发送该上行数据。
网络设备#B可以监听其授权或分配的无线资源(包括目标无线资源)，从而，可以基于第二RAT，通过该目标无线资源，接收到来自终端设备的上行数据。
并且，网络设备#B基于第二RAT接收数据的方法和过程可以与现有技术相似，这里，为了避免赘述，省略其详细说明。
另外，在本发明实施例中，网络设备#B在接收到来自终端设备的上行数据之后，可以将该上行数据通过例如光纤等理想回程线路输给网络设备#A，也可以将该上行数据直接传输至核心网设备或该上行数据所对应的业务的业务服务器，本发明并未特别限定。

作为示例网络设备#A可以获知该第二协议层集合所包括的具体协议层，可以列举以下方式：
即，网络设备#B可以向网络设备#A发送用于指示该第二协议层集合的指示信息(即，第四指示信息)，从而，网络设备#A可以根据该第四指示信息，确定该第二协议层集合，即，协议栈#B中对该目标数据进行处理的协议层，从而，可以基于第二协议层集合，基于协议栈#A中的协议层，对该第四指示信息进行封装处理，以生成符合第一RAT的传输要求的第四指示信息，并将该第四指示信息发送给终端设备
具体地说，例如，如图3所示，当该目标数据是网络设备#B通过协议栈#B的RRC层(即，第二协议层集合的一例)处理后生成的RRC层数据时，网络设备#B可以将该目标数据作为来自于高层(即，RRC层之上的协议层)的信息，并通过协议栈#A的RRC层、PDCP层、RLC层、MAC层和PHY层(即，第一协议层集合的一例)对该目标数据进行封装处理。
或者，当该目标数据是网络设备#B通过协议栈#B的RRC层和RLC层(即，第二协议层集合的另一例)，或者，协议栈#B的RLC层(即，第二协议层集合的再一例)处理后生成的RLC信息时，网络设备#B可以将该目标数据作为来自于高层(即，RLC层之上的协议层)的信息，并通过协议栈#A的RLC层、MAC层和PHY层(即，第一协议层集合的另一例)对该目标数据进行封装处理。
再或者，当该目标数据也可以是网络设备#B通过协议栈#B的RRC层、RLC层和MAC层(即，第二协议层集合的再一例)，或者，协议栈#B的MAC层(即，第二协议层集合的再一例)处理后生成的MAC信息时，网络设备#B可以将该目标数据作为来自于高层(即，MAC层之上的协议层)的信息，并通过协议栈#A的MAC层和PHY层(即，第一协议层集合的再一例)对该目标数据进行封装处理，以生成第一指示信息。
再或者，当该目标数据也可以是网络设备#B通过协议栈#B的RRC层、RLC层、MAC层和PHY层(即，第二协议层集合的再一例)处理后生成的PHY信息时，网络设备#B可以将该目标数据作为来自于高层(即，PHY层之上的协议层)的信息，并通过协议栈#A的PHY层(即，第一协议层集合的再一例)对该目标数据进行封装处理。
应理解，网络设备#B对目标数据进行处理时所使用的协议栈#B的具体协议层仅为示例性说明，本发明并不限定于此，可以根据网络设备#A生成目标数据时所使用的协议栈#A的具体协议层进行适应性变更。
并且，网络设备#A中上述各协议层的处理过程和方法可以与现有技术相似，这里，为了避免赘述，省略其详细说明。
需要说明的是，在本发明实施例中，网络设备#B可以将上述目标数据和第四指示信息承载于同一消息(或者说，报文、数据包)中一并发送给网络设备#A。或者，网络设备#B可以将上述目标数据和第四指示信息承载于不同消息(或者说，报文、数据包)中分别发送给网络设备#A。再或者，该目标数据和第四指示信息也可以作为不同的字段而承载于同一信息中，本发明并未特别限定。
如上所述，由于该目标数据经由第一协议层集合和第二协议层集合双方的封装处理，因此，终端设备也需要获知该第一协议层集合和第二协议层集合所包括的具体协议层，才能够基于设置在该终端设备内的相应的协议栈层(即，协议栈#A’的部分或全部协议层，以及协议栈#B’的部分或全部协议层)对该目标数据进行解封装处理，以获得该目标数据的具体内容。
在本发明实施例中，终端设备可以根据RAT类型指示信息，确定使用协议栈#B’进行解封装处理。
下面，对该终端设备确定协议栈#A’中与第一协议层集合相对应的协议层，以及协议栈#B’中与第二协议层集合相对应的协议层的方法进行详细说明。
方法1
可选地，在该第一网络设备基于该第一RAT，向该终端设备发送该目标数据和用于指示该第二RAT的RAT类型指示信息之前，该方法还包括：
该第一网络设备根据该第一协议层集合，对用于指示该第二RAT的RAT类型指示信息进行封装处理。
具体地说，在本发明实施例中，网络设备#A可以根据第二协议层集合，将该RAT类型指示信息封装在目标数据相应的数据结构中，具体地说，目标数据可以包括多个数据结构，每个数据结构是经过所对应的协议层的封装处理而生成的，相应地，每个数据结构可以经过所对应的协议层的解封装处理后获得。
例如，当第二协议层集合包括RRC层时，经过第一协议层集合的封装处理后的目标数据可以包括：RRC数据结构(即，经由协议栈#A的RRC层封装处理而生成的数据结构，可以经由协议栈#A’的RRC层解封装处理而获得)，PDCP数据结构(即，经由协议栈#A的PDCP层处理而生成的数据结构，可以经由协议栈#A’的PDCP层解封装处理而获得)，RLC数据结构(即，经由协议栈#A的RLC层处理而生成的数据结构，可以经由协议栈#A’的RLC层解封装处理而获得)，MAC数据结构即，经由协议栈#A的MAC层处理而生成的数据结构，可以经由协议栈#A’的MAC层解封装处理而获得)，PHY数据结构(即，经由协议栈#A的PHY层处理而生成的数据结构，可以经由协议栈#A’的PHY层解封装处理而获得)。
此情况下，网络设备#A可以将RAT类型指示信息封装在RRC数据结构中，从而，终端设备在通过协议栈#A’的RRC层的解封装处理而获得RAT类型指示信息，可以根据该RAT类型指示信息所使用的数据结构(即，RRC数据结构)，确定该目标数据是经过协议栈#B的RRC层处理而生成的数据，从而，可以启动协议栈#B’，并通过协议栈#B’的RRC层对通过协议栈#A’的RRC层的解封装处理而获得上述RRC数据结构进一步解封装，以获得目标数据的具体内容。
再例如，当第二协议层集合包括RRC层和RLC层(或者，RRC层、PDCP层和RLC层)时，经过第一协议层集合的封装处理后的目标数据可以包括：RLC数据结构，MAC数据结构，PHY数据结构。
此情况下，网络设备#A可以将RAT类型指示信息封装在RLC数据结构，从而，终端设备在通过协议栈#A’的RLC层的解封装处理而获得RAT类型指示信息，可以根据该RAT类型指示信息所使用的数据结构(即，RLC层)，确定该目标数据是经过协议栈#B的RLC层处理而生成的数据，从而，可以启动协议栈#B’，并通过协议栈#B’的RLC层和RRC层(或者，RLC层、PDCP层和RRC层)对通过协议栈#A’的RLC层的解封装处理而获得上述RLC数据结构进一步解封装，以获得目标数据的具体内容。
再例如，当第二协议层集合包括RRC层、RLC层和MAC层(或者，RRC层、PDCP层、RLC层和MAC层)时，经过第一协议层集合的封装处理后的目标数据可以包括：MAC数据结构，PHY数据结构。
此情况下，网络设备#A可以将RAT类型指示信息封装在MAC数据结 构，从而，终端设备在通过协议栈#A’的MAC层的解封装处理而获得RAT类型指示信息，可以根据该RAT类型指示信息所使用的数据结构(即，MAC数据结构)，确定该目标数据是经过协议栈#B的MAC层处理而生成的数据，从而，可以启动协议栈#B’，并通过协议栈#B’的MAC层、RLC层和RRC层(或者，MAC层、RLC层、PDCP层和RRC层)对通过协议栈#A’的MAC层的解封装处理而获得上述MAC数据结构进一步解封装，以获得目标数据的具体内容。
再例如，当第二协议层集合包括PHY层、RRC层、RLC层和MAC层(或者，PHY层、RRC层、PDCP层、RLC层和MAC层)时，经过第一协议层集合的封装处理后的目标数据可以包括：PHY数据结构。
此情况下，网络设备#A可以将RAT类型指示信息封装在PHY数据结构，从而，终端设备在通过协议栈#A’的PHY层的解封装处理而获得RAT类型指示信息，可以根据该RAT类型指示信息所使用的数据结构(即，PHY数据结构)，确定该目标数据是经过协议栈#B的PHY层处理而生成的数据，从而，可以启动协议栈#B’，并通过协议栈#B’的PHY层、MAC层、RLC层和RRC层(或者，PHY层、MAC层、RLC层、PDCP层和RRC层)对通过协议栈#A’的PHY层的解封装处理而获得上述PHY数据结构进一步解封装，以获得目标数据的具体内容。
方法2
可选地，该方法还包括：
该第一网络设备基于该第一RAT，向该终端设备发送用于指示该第二协议层集合的第四指示信息。
具体地说，在本发明实施例中，网络设备#A可以通过协议栈#A对该第四指示信息进行封装处理，以生成终端设备能够通过第一RAT接收到的信息。
需要说明的是，在本发明实施例中，网络设备#A可以将上述目标数据和第四指示信息承载于同一消息(或者说，报文、数据包)中一并发送给终端设备。或者，网络设备#A可以将上述目标数据和第四指示信息承载于不同消息(或者说，报文、数据包)中分别发送给终端设备。再或者，目标数据和第四指示信息也可以作为不同的字段而承载于同一信息中，本发明并未特别限定。
由此，终端设备能够通过第一RAT接收到网络设备#A发送的目标数据和第四指示信息。
从而，终端设备可以通过协议栈#A’对第四指示信息进行解封装处理，以确定第二协议栈集合和第一协议栈集合。
并且，终端设备可以根据第一协议栈集合对目标数据进行解封装处理，并根据第一协议栈集合对所获得的数据进一步解封装，从而能够获得目标数据的内容。
具体地说，例如，如图3所示，当该目标数据是网络设备#B通过协议栈#B的RRC层(即，第二协议层集合的一例)处理后生成的RRC层数据时，则网络设备#A所发送的目标数据是网络设备#A通过协议栈#A的RRC层、PDCP层、RLC层、MAC层和PHY层(即，第一协议层集合的一例)对该目标数据进行封装处理而生成的，此情况下，终端设备可以根据第四指示信息，确定第一协议层集合(即，包括协议栈#A的RRC层、PDCP层、RLC层、MAC层和PHY层)和第二协议层集合(即，包括协议栈#B的RRC层)，并通过该第一协议层集合所对应的协议层(即，包括协议栈#A’的RRC层、PDCP层、RLC层、MAC层和PHY层)对该目标数据进行解封装处理，从而，能够获得网络设备#B发送给网络设备#A的经过第二协议层集合的封装处理而生成的数据，并根据该第二协议层集合所对应的协议层(即，包括协议栈#B’的RRC层)，该数据进行进一步的解封装处理，以确定目标数据的具体内容。
再例如，当该目标数据是网络设备#B通过协议栈#B的RRC层和RLC层(即，第二协议层集合的另一例)处理后生成的RLC层PDU时，则网络设备#A所发送的目标数据是网络设备#A通过协议栈#A的RLC层、MAC层和PHY层(即，第一协议层集合的另一例)对该目标数据进行封装处理而生成的，此情况下，终端设备可以根据第四指示信息，确定第一协议层集合(即，包括协议栈#A的RLC层、MAC层和PHY层)和第二协议层集合(即，包括协议栈#B的RRC层和RLC层)，并通过该第一协议层集合所对应的协议层(即，包括协议栈#A’的RLC层、MAC层和PHY层)对该目标数据进行解封装处理，从而，能够获得网络设备#B发送给网络设备#A的经过第二协议层集合的封装处理而生成的数据，并根据该第二协议层集合所对应的协议层(即，包括协议栈#B’的RRC层和RLC层)，该数据进行进 一步的解封装处理，以确定目标数据的具体内容。
再例如，当该目标数据是网络设备#B通过协议栈#B的RRC层、RLC层和MAC层(即，第二协议层集合的另一例)处理后生成的MAC层PDU时，则网络设备#A所发送的目标数据是网络设备#A通过协议栈#A的MAC层和PHY层(即，第一协议层集合的另一例)对该目标数据进行封装处理而生成的，此情况下，终端设备可以根据第四指示信息，确定第一协议层集合(即，包括协议栈#A的MAC层和PHY层)和第二协议层集合(即，包括协议栈#B的RRC层、RLC层和MAC层、)，并通过该第一协议层集合所对应的协议层(即，包括协议栈#A’的MAC层和PHY层)对该目标数据进行解封装处理，从而，能够获得网络设备#B发送给网络设备#A的经过第二协议层集合的封装处理而生成的数据，并根据该第二协议层集合所对应的协议层(即，包括协议栈#B’的RRC层、RLC层和MAC层)，该数据进行进一步的解封装处理，以确定目标数据的具体内容。
应理解，终端设备对第四指示信息进行处理时所使用的协议栈#A’和协议栈#B’的具体协议层仅为示例性说明，本发明并不限定于此，可以根据网络设备#A生成目标数据时所使用的协议栈#A(或者说，网络设备#B生成目标数据时所使用的协议栈#B)的具体协议层进行适应性变更。
并且，终端设备中上述各协议层的处理过程和方法可以与现有技术相似，这里，为了避免赘述，省略其详细说明。
可选地，该多种数据与多个数据类型信息一一对应，每个数据类型信息能够在该多种数据中唯一地指示所对应的数据，该第四指示信息具体为该目标数据所对应的数据类型信息。
具体地说，在本发明实施例中，不同数据类型的数据可以是网络设备#B通过不同的协议层生成的，例如，RRC层数据可以是网络设备#B经由RRC层处理后生成的，RLC层数据可以是网络设备#B经由RLC层处理后生成的，MAC层数据可以是网络设备#B经由MAC层处理后生成的。此情况下，终端设备仅需要获知所接收到的目标数据的数据类型，便能够确定协议栈#B中用于对该目标数据进行解封装处理的协议层。因此，在本发明实施例中，可以预先规定对各种类型的数据进行封装(或解封装)处理时使用的协议层，例如，在网络设备和终端设备中存储数据与协议层之间的映射关系表项，网络设备和终端设备均基于该映射关系表项进行数据处理，从而，可以将该目 标数据所对应的数据类型信息，作为上述第四指示信息。
可选地，该第二协议栈所包括的多个协议层与多个协议层标识一一对应，每个协议层标识能够在该多个协议层中唯一地指示所对应的协议层，该第四指示信息具体为该第二协议层集合所包括的协议层的协议层标识。
具体地说，在本发明实施例中，该第四指示信息也可以是该第二协议层集合中位于最低层的协议层的指示信息，例如，当网络设备#B生成的目标数据为MAC层PDU时，该第二协议层集合包括RRC层、RLC层和MAC层，此时，可以将能够唯一地指示MAC层的标识作为第四指示信息，从而，当终端设备接收到该MAC层的标识时，可以确定该第二协议层集合包括协议栈#B的MAC层以上的协议层，进而可以通过协议栈#A’的PHY层和MAC层对网络设备#A发送的目标数据进行解封装处理，并通过协议栈#B’的RRC层、RLC层和MAC层对所获得的数据进一步进行解封装处理。
或者，该第四指示信息也可以是该第一协议层集合中位于最高层的协议层的指示信息，例如，当网络设备#B生成的目标数据为MAC层PDU时，该第一协议层集合包括MAC层和PHY层，此时，可以将能够唯一地指示MAC层的标识作为第四指示信息，从而，当终端设备接收到该MAC层的标识时，可以确定该第二协议层集合包括协议栈#B的MAC层以上的协议层，进而可以通过协议栈#A’的PHY层和MAC层对网络设备#A发送的目标数据进行解封装处理，并通过协议栈#B’的RRC层、RLC层和MAC层对所获得的数据进一步进行解封装处理。
通过上述方法1或方法2，终端设备能够准确的确定用于解封装处理所使用的协议层，能够提高数据处理的效率和速度，进一步改善用户体验。
可选地，第一网络设备进行与第二网络设备之间的协商处理，包括：
第一网络设备进行与第二网络设备之间的协商处理，以确定第二网络设备处于终端设备的覆盖范围内。
具体地说，网络设备#A可以从系统中的一个或多个的网络设备中，确定处于终端设备覆盖范围内的网络设备#B，即，网络设备#B由于处于终端设备的覆盖范围内，因此，能够接收到终端设备发送的上行数据。
下面，对网络设备#A确定网络设备#B处于终端设备的覆盖范围内的方法进行示例性说明。
可选地，所述第一网络设备进行与第二网络设备之间的协商处理，以确 定第二网络设备处于终端设备的覆盖范围内。包括：
所述第一网络设备，接收所述第二网络设备发送的所述终端设备的设备标识，其中，所述终端设备的设备标识是所述第二网络设备在通过所述第二RAT，接收到所述终端设备发送的携带有所述终端设备的设备标识的信号之后发送的；
所述第一网络设备根据所述终端设备的设备标识，确定所述第二网络设备处于所述终端设备的覆盖范围内。
具体地说，在本发明实施例中，第一网络设备和上述备选的网络设备之间(例如，网络设备#A和网络设备#B之间)可以设置有通信连接，例如，通过光纤、铜线或无线链路等实现的通信连接。
在本发明实施例中，支持第二RAT的终端设备可以使用该第二RAT发送携带有该终端设备的设备标识的信号，例如，参考信号等。
需要说明的是，以上列举的参考信号仅为示例性说明，本发明并为限定于此，其他能够携带终端设备的设备标识的信号均落入本发明保护范围内。
并且，终端设备的设备标识可以用于唯一的指示该终端设备，例如，可以是该终端设备的手机号码等。
另外，在本发明实施例中，终端设备使用该第二RAT发送携带有该终端设备的设备标识的信号的过程可以周期性进行，也可以是在网络设备#A判定需要通过其他网络设备接收该终端设备的上行数据时，根据网络设备#A的指示进行，本发明并未特别限定。
当终端设备移动至例如图1所示位置时，网络设备#B处于该终端设备的覆盖范围内，即，网络设备#B能够使用该第二RAT接收到终端设备发送的携带有终端设备的设备标识的信号，从而，网络设备#B可以根据该信号，确认其处于终端设备的覆盖范围内，即，网络设备#B能够接收到终端设备发送的上行数据。
进而，网络设备#B可以通过上述通信链路将指示该网络设备#B处于该终端设备的覆盖范围内(或者说，该网络设备#B能够接收到终端设备发送的上行数据)的指示信息，发送给网络设备#A。例如，该指示信息可以包括该终端设备的设备标识。
从而，网络设备#A可以根据来自该网络设备#B的指示该网络设备#B处于该终端设备的覆盖范围内的指示信息(例如，该终端设备的设备标识)， 确定该网络设备#B处于该终端设备的覆盖范围内。
此外，当该携带有终端设备的设备标识的信号为参考信号时，网络设备#B还可以根据该参考信号，对终端设备与网络设备#B之间的信道进行测量，并基于测量结果进一步判定是否能够有效地为该终端设备服务(例如，是否能够准确地接收到终端设备发送的上行数据)，并在根据测量结果，判定终端设备与网络设备#B之间的信道的信道质量较高(例如，高于预设的门限值)，则网络设备#B可以向网络设备#A发送指示该网络设备#B处于该终端设备的覆盖范围内(或者说，该网络设备#B能够接收到终端设备发送的上行数据)的指示信息。
或者，当该携带有终端设备的设备标识的信号为参考信号时，网络设备#B还可以根据该参考信号，对终端设备与网络设备#B之间的信道进行测量，并将该测量结果连同上述指示该网络设备#B处于该终端设备的覆盖范围内(或者说，该网络设备#B能够接收到终端设备发送的上行数据)的指示信息一并发送给网络设备#A，从而，网络设备#A可以基于测量结果判定是否能够有效地为该终端设备服务(例如，是否能够准确地接收到终端设备发送的上行数据)，并在根据测量结果，判定终端设备与网络设备#B之间的信道的信道质量较高(例如，高于预设的门限值)时，确定网络设备#B处于终端设备的覆盖范围内。
应理解，以上列举的网络设备#A确定网络设备#B的覆盖范围内的方法和过程仅为示例性说明，本发明并未限定于此，例如，网络设备#A还可以预先从网络运营商获取用于指示网络设备#B的位置的指示信息，并从终端设备获取指示该终端设备的位置和覆盖范围的指示信息，从而，可以根据上述指示信息，确定网络设备#B是否位于终端设备的覆盖范围内。例如，在本发明实施例中，可以使用例如基站定位法、全球定位系统(GPS，Global Position System)定位法等通常的终端设备定位方法对终端设备进行定位，从而确定该终端设备的位置。
可选地，该终端设备处于该第二网络设备的覆盖范围外。
具体地说，如图1所示，当终端设备处于第二网络设备的覆盖范围以外时，由于第二网络设备发送的例如，系统信息或广播信息等无法发送至终端设备，因此，终端设备无法完成针对第二网络设备的接入处理，也无法接收到第二网络设备下发的调度信息，即，根据现有技术，终端设备无法向第二 网络设备发送上行数据。
与此相对，根据本发明实施例的无线通信方法200，由第一网络设备向终端设备下发该第二网络设备授权或分配的目标无线资源的指示信息，即使在第二网络设备位于终端设备的覆盖范围以外的情况下，仍然能够完成针对终端设备的资源调度，能够实现终端设备向第二网络设备发送上行数据。
应理解，图1所示的终端设备和第二网络设备的位置关系仅为示例性说明，只要确保第二网络设备位于终端设备的覆盖范围内即可，本发明并未限定，例如，终端设备也可以位于第二网络设备的覆盖范围内。
需要说明的是，在本发明实施例中，第一网络设备可以将该目标数据和用于指示该第二RAT的RAT类型指示信息封装在同一数据包中，一并发送给终端设备，或者，第一网络设备可以将该目标数据和用于指示该第二RAT的RAT类型指示信息封装在不同数据包中，分别发送给终端设备，本发明并未特别限定
另外，在本发明实施例中，该目标数据可以是用户面数据，也可以是控制面数据，本发明并未特别限定。
并且，在本发明实施例中，在网络设备#B通过网络设备#A向终端设备传输信息(例如，上述目标无线资源的指示信息、第二RAT的指示信息等系统广播信息或反馈信息)时，还可以将该信息的属性的指示信息一并传输至网络设备#A，进而传输至终端设备，从而，终端设备能够根据该信息的属性，进行适应性处理。
这里，“属性”可以包括：该信息所属于的层面，即，控制面信息或用户面信息。
或者，“属性”还可以包括：收发该信息所使用的RAT。
再或者，“属性”还可以包括：收发该信息所使用的协议层。
在本发明实施例中，终端设备在根据该第一指示信息，确定目标无线资源后，可以通过该目标无线资源，使用第二RAT向网络设备#B发送上行数据。并且，该终端设备与网络设备#B之间传输上行数据的方法和过程可以与现有技术相似，这里，为了避免赘述，省略其详细说明。
