- LTE-Unlicensed uses unlicensed spectrum to increase available network traffic for cellular data communications.
- LTE-U uses unlicensed spectrum to increase available network traffic for cellular data communications.
- various operators and equipment vendors are strongly promoting the deployment of LTE-U solutions in the WIFI 5GHz frequency band.
- WIFI 5GHz frequency band the industry is still constantly exploring improvements and scenario testing.
- LTE-U The traditional LTE is applied to the licensed frequency band and has absolute use rights to the working frequency band.
- the deployment of LTE-U's 5 GHz in the mature LTE network means that the downlink unlicensed public frequency band channel is monopolized. Therefore, there is widespread controversy in the industry for the coexistence of LTE-U and WIFI 5 GHz channels on unlicensed bands. From the perspective of the role of the WIFI terminal, interference can be divided into the following two interferences.
- the first is external interference, and the terminal acts as a WIFI STA.
- the quality of WIFI is subject to interference from the outside.
- the WIFI channel access protocol adopts the competition mode, carrier-aware multiple access and collision avoidance channel access (CSMA/CA), and the network node (Access Point or terminal) must listen to the channel before using a certain channel for transmission. Whether it is idle, then decide whether to occupy and transmit the signal LBT (Listen Before Talk); if the channel is occupied, delay a random time and then start the corresponding program to avoid the conflict.
- LBT Listen Before Talk
- the WIFI STA may be in the listening state for a long time, and eventually the terminal user WIFI access fails.
- the 3GPP organization proposed the LBT support for LTE-U in the LTE R13 standard, namely LAA (License Assisted Access); Qualcomm proposes the use of Carrier Sense Adaptive Transmission (CSAT) technology, which can have multiple users in the network. In the case of coexistence, frequency usage can be allocated more reasonably.

- LTE-U is the use of unlicensed public frequency bands to compensate for the lack of bandwidth of the currently licensed band.
- the unlicensed frequency band is mainly used by WIFI and Bluetooth, including the 2.4 GHz band and the 5 GHz band. Since the WIFI with the largest user amount gathers a large number of devices in the 2.4 GHz band, the channel is crowded. Therefore, the application research of LTE-U is currently concentrated on the 5 GHz band. As shown in Figure 1, relying on the WIFI band allocation, the current LTE-U mainstream uses the 5 GHz band; among them, the 5 GHz band is divided into three segments of UNII (Unlicensed National Information Infrastructure).
- UNII Unlicensed National Information Infrastructure
- Table 1 The range of LTE-U frequency bands currently defined in the existing LTE-U Forum standard is shown in Table 1, and Table 1 is the frequency band range of LTE-U.
- LTE-U wireless network access modes there are two types, one is the downlink enhancement mode (SDL), as shown in the left side of Figure 2, and the second is the carrier aggregation mode (carrier). Aggregation, CA), as shown on the right side of Figure 2.
- SDL downlink enhancement mode
- carrier carrier aggregation mode
- CA carrier aggregation mode

- 5G fifth-generation mobile communication system
- WIFI Hotspot refers to converting the receiving GPRS, 3G or 4G signals of the terminal into WIFI signals and then sending them out, so that the terminal becomes an AP and provides the WIFI STA (Station) network traffic transmission service; WIFI P2P is also called WIFI Direct. It refers to a local area network that allows wireless devices to communicate directly in a peer-to-peer fashion, forming a Group Owner and Group Client mode. Both of these are high-speed, fast and simple WIFI applications.
- WIFI Hotspot and P2P can be used on 5GHz and 2.4GHz channels, but usually the software default is to use the 5GHz band, and the 2.4GHz band will only be retired after trying to access the channel.
- WIFI Hotspot provides a menu of channel selection lists on the HMI, allowing users to control the use of channels such as 2.4GHz+5GHz, 5GHz only and 2.4GHz only.
- the current mainstream mobile intelligent terminals can provide users with various wireless communication services provided by operators, and have a good user experience in the human-machine interface. Therefore, most of them use BP (Baseband Processor) and AP (Application Processor) cooperative communication mechanisms in the software structure.
- the main role of BP is to send and receive data for various terminals to communicate with the wireless network; while the AP is running an operating system and application software such as Android, Windows, and the like.
- the two messages are transmitted and interacted by the TLV (Type Length Value, message type, length, content) format.
- TLV Type Length Value, message type, length, content
- the LTE-U receiving antenna will receive a large co-channel interference, which is called self-interference. From the results of the laboratory OOBE test data, when the two work at the same frequency, the LTE-U receiving signal will be affected to reach about 10dBm. If the center frequencies of the two overlap, the LTE-U receiving signal has a greater impact. In this way, the rate at which the terminal accesses the network is directly compromised; the quality of the provided WIFI AP/P2P (depending on the operator's data capabilities) is also reduced.

- the AP side configures the corresponding system parameter value according to the c status change message. Because the system parameters are global variables, both WIFI Hotspot and P2P processing modules can be accessed.

本发明涉及LTE-U技术领域,特别涉及一种移动终端LTE-U与WIFI5G信道共存的自干扰解决方法及系统。
随着无线移动用户数量和各种互联网访问量的急剧增长,使得无限增长的无线需求与有限的授权频谱资源之间的矛盾日益凸显。为了缓解运营商的网络压力,将资源相对丰富的免授权频段引入到LTE网络中成为一种新的尝试。LTE-Unlicensed(简称LTE-U),是使用非授权频谱来给蜂窝数据通信增加可用网络流量。目前各个运营商与设备商正在强力推进在WIFI 5GHz频段上部署LTE-U方案,但对于LTE-U与WIFI能否在非授权频段上共存,业界仍在不断地探索改进与场景测试。
传统的LTE上应用于授权频段,拥有对工作频段的绝对使用权,在现成熟的LTE网络中部署LTE-U的5GHz使用,意味着会独占下行非授权的公共频段信道。因此对于LTE-U与WIFI 5GHz信道上能否在非授权频段上共存,业界普遍存在着争议。从WIFI终端的使用角色来看,干扰可以分为以下两个干扰。
第一是外部干扰,终端作为WIFI STA,WIFI的使用质量面临来自外部的干扰问题。WIFI信道接入协议采用竞争方式,载波感知多址接入和冲突避免信道接入方式(CSMA/CA),网络节点(Access Point或终端)在使用某个信道进行传输之前,必须先监听该信道是否空闲,再决定是否占用并传输信号LBT(Listen Before Talk);如果信道被占用则推迟一段随机时间再启动相应程序以避免冲突。LTE-U在占用5GHz非授权频段信道时,就可能会使WIFI STA长时间处于监听状态,最终导致终端用户WIFI接入失败。为此,3GPP组织在LTE R13标准中对LTE-U提出了支持LBT的要求,即LAA(License Assisted Access);高通提出使用载波感应适配传输(CSAT)的技术,能够在网络中有多用户共存的情况下能够更合理地分配频率使用。
第二种是自干扰,终端作为WIFI AP/P2P,当WIFI信号发射器工作在5GHz,此时LTE-U接收天线工作将会收到较大的同频干扰,简称自干扰。从实验室OOBE测试数据结果看,两者同频工作时,LTE-U接收信号会被影响达到10dBm 左右。若两者中心频点重叠,LTE-U接收信号影响更大。这样,将会直接体现在终端访问网络的速率大打折扣;对提供的WIFI AP/P2P质量(依赖于运营商数据能力)也会降低,从而带来了大大的不便。
因而现有技术还有待改进和提高。
【发明内容】

本发明提供一种移动终端LTE-U与WIFI5G信道共存的自干扰解决方法及系统。为使本发明的目的、技术方案及效果更加清楚、明确,以下参照附图并举实施例对本发明进一步详细说明。应当理解,此处所描述的具体实施例仅用 以解释本发明,并不用于限定本发明。
首先对本发明所述的自干扰详细阐述如下。LTE-U是利用非授权的公用频段来弥补当前授权频段频宽的不足。在目前的频率使用划分体系下,非授权频段主要被WIFI和蓝牙所使用,包括2.4GHz频段和5GHz频段。由于拥有最大用户量的WIFI在2.4GHz频段聚集了大量的设备,信道拥挤不堪。因此目前LTE-U的应用研究集中在5GHz频段上。如图1所示,依托WIFI频段划分,目前LTE-U主流使用的是5GHz的频段;其中,5GHz频段被划分成3段UNII(Unlicensed National Information Infrastructure,非授权国内信息基础建设)。
现有LTE-U论坛标准中目前定义的LTE-U使用频段范围如表1所示,表1为LTE-U的频段范围。
| Band号 | 下行频段(MHz) | 下行最低频点 | 下行频点的范围 |
| 252 | 5150 | 255144 | 255144-256143 |
| 255 | 5725 | 260894 | 260894-262143 |
表1
基于传统的LTE网络下,LTE-U的无线网络接入方式目前有两种,一种是下行增强方式(Supplemental Downlink,SDL),如图2的左边示意;第二种是载波聚合方式(Carrier Aggregation,CA),如图2的右边示意。其中,图2所示为移动终端,譬如手机或平板电脑等。
目前,已经有许多公司以及研究机构向3GPP提出在非授权频段部署LTE技术,即LTE-U,来加速LTE的公共服务区域传输。美国Verizon运营商已经对LTE-U技术进行了测试,并从2016年开始在5GHz频段上部署LTE-U技术。同样,T-Mobile美国公司今年也已于2016年在5GHz频段上部署其称之为“授权协助接入”(Licensed Assistance Access,LAA,LTE-U的一种形式)的技术。LTE-U很好地缓解了运营商频谱资源的紧张,能为用户带来更好的数据体验,其带来的商业价值无可限量。与此同时,LTE-U作为第五代移动通信系统(5G)增强技术,吸引了全世界范围内移动通信研究工作者的广泛关注。
目前智能终端大多都集合了WIFI芯片,不仅能使用周围的无线互联网络,也能作为无线Access Point对外提供服务,主要的有WIFI Hotspot(热点)和WIFI P2P(Point 2Point,点对点)应用。WIFI热点是指把终端的接收GPRS、3G或4G信号转化为WIFI信号再发出去,这样终端就成了一个AP,提供给WIFI STA(Station)网络流量的传送服务;WIFI P2P也称WIFI Direct,是指允许无线设备以点对点形式互连来直接通信,构成Group Owner和Group Client 模式的局域网络。这两种都是用户使用频率较高的,快速简单的WIFI应用。WIFI Hotspot和P2P都可以在5GHz和2.4GHz信道上使用,但通常软件上默认优选使用5GHz频段,只有在尝试接入该信道失败后才会退避使用2.4GHz频段。另外,WIFI Hotspot在人机界面上提供了信道选择列表的菜单,用户可自主控制信道的使用,比如2.4GHz+5GHz,5GHz only和2.4GHz only。
而当前主流的移动智能终端,都能提供用户使用运营商提供的各种无线通信业务,并且在人机界面的良好用户体验。因此它们大多在软件结构上都采用BP(Baseband Processor,基带处理)和AP(Application Processor,应用处理)协同通信机制。BP主要的作用是发送和接受各种终端与无线网络通信的数据;而AP则是运行操作系统和应用软件,如Android、Windows等。通常,两者通过TLV(Type Length Value,消息类型,长度,内容)格式的消息来进行两边信息的传递和交互。终端的这种通信机制给开发者提供了可扩展的平台。
终端作为WIFI AP/P2P,当WIFI信号发射器工作在5GHz,此时LTE-U接收天线工作将会收到较大的同频干扰,简称自干扰。从实验室OOBE测试数据结果看,两者同频工作时,LTE-U接收信号会被影响达到10dBm左右。若两者中心频点重叠,LTE-U接收信号影响更大。这样,将会直接体现在终端访问网络的速率大打折扣;对提供的WIFI AP/P2P质量(依赖于运营商数据能力)也会降低。本发明提出的技术方案就是用来解决这种自干扰的问题。
请参阅图3,本发明了提供一种移动终端LTE-U与WIFI5G信道共存的自干扰解决方法,所述自干扰解决方法,包括:
S100、LTE协议栈的无线资源控制层接收LTE-U的状态变化消息,通过非接入层的注册模块上报至移动终端应用层;
S200、根据LTE-U的状态变化消息配置对应的系统参数,利用系统参数设置WIFI可用信道列表来控制5G Hz信道的启闭。
下面结合具体的实施例对上述步骤进行详细的描述。
如图4所示,图4为本发明提供的移动终端LTE-U与WIFI5G信道共存的自干扰解决方法的软件架构示意图,具体来说,本发明的原理是,终端在Modem侧LTE协议栈的RRC(无线资源控制)层收到LTE-U的状态变化消息,经过NAS(非接入层)的REG(注册模块)层,将消息上报给终端AP(具体为移动终端应用层)。AP侧接收到状态变化消息后,根据c状态变化消息配置对应的系统参数值。因为该系统参数为全局变量,在WIFI Hotspot和P2P处理模块都 可被访问。这样,就可以利用系统参数来控制WIFI可用信道列表,即2.4GHz only,或者2.4GHz+5GHz。
本发明根据LTE-U的状态变化对应控制WIFI 5GHz信道的开启,在LTE-U处于激活状态时关闭WIFI 5GHz信道,在LTE-U处于去激活状态时开启WIFI5GHz信道,从而在移动终端上错开对5GHz信道使用时间,避免了WIFI信号发射器工作在5GHz时LTE-U接收天线工作将会收到较大的同频干扰的问题,使得用户既能良好享用LTE-U网络带来的高速率,又保证了自身WIFI热点和P2P对外的正常提供,带来了极大的方便。
优选地,所述状态变化消息包括:LTE-U作为辅小区的小区状态、小区标识号、小区频点和小区数据带宽;其中所述小区状态包括激活状态和去激活状态;所述系统参数包括:用于启动WIFI热点信道检查的第一系统参数和用于启动WIFI P2P信道检查的第二系统参数。请参阅图5,图5为本发明提供的状态变化消息内容结构示意图,如图所示,本发明按照消息格式通用的TLV格式,Type为Service_NAS,Value(内容)部分设计如图5所示,其中,cell_state为小区状态(包括激活态和非激活态),cell_id为小区标识号,freq为小区频点,bandwidth为小区数据带宽,进而利用支持的BP和AP通信机制,将该消息上报到终端上层的AP侧(也就是移动终端Application层)。AP侧接收到状态变化消息后,根据cell_state配置对应的系统参数值,其中第一个系统参数persist.radio.wifi.hotspot.lteu的值变化启动WIFI热点信道检查,而第二个系统参数persist.radio.wifi.p2p.lteu则启动WIFI P2P信道检查。
在实际应用时,LTE-U小区的状态包括激活状态和去激活状态。
一方面,优选地,当移动终端进入LTE-U激活状态时,所述步骤S100具体包括:
S111、当移动终端进入LTE-U激活状态,通过空口消息RRC连接重配置过程中的辅小区的添加列表携带LTE-U配置信息,经移动终端确认后将所述LTE-U作为辅小区;
S112、移动终端调制解调器利用移动终端BP和AP通信机制,将辅小区的状态变化消息传送到移动终端应用层。
具体来说,请参阅图6,图6为本发明提供的移动终端LTE-U与WIFI5G信道共存的自干扰解决方法进入激活状态的实现流程图,图6图为终端进入LTE-U到激活态,软件对于WIFI可用信道列表的控制。首先,网络侧通过空 口消息RRC Connection Reconfiguration(RRC连接重配置)过程中的sCellToAddModList(辅小区的添加列表)携带LTE-U配置信息,终端确认后将该LTE-U作为辅小区;终端Modem利用自身BP和AP通信机制,将状态变化消息传送到Application层。此时,消息中的cell_state字段值为Active。
优选地,所述步骤S200具体包括:
S211、移动终端应用层接收所述状态变化消息,将第一系统参数和第二系统参数的参数值设置为真,启动WIFI信道使用检查流程,将WIFI可用信道列表设置成2.4GHz,控制5G Hz信道关闭。
具体来说,在步骤S112之后,接着Application在收到状态变化消息会先将两个系统参数值(即对应为图6的persist.radio.wifi.hotspot.lteu和persist.radio.wifi.p2p.lteu)从默认false(假)设置为true(真),并以广播该系统值变化来启动WIFI信道使用的检查流程,然后将WIFI可用信道列表设置成2.4GHz。第一个系统参数persist.radio.wifi.hotspot.lteu的值变化启动WIFI热点信道检查,而第二个系统参数persist.radio.wifi.p2p.lteu则启动WIFI P2P信道检查。
优选地,请参阅图7,图7为本发明提供的WIFI信道使用的检查流程示意图,本发明提供的WIFI信道检查流程包括对WIFI热点的查询或WIFI P2P的查询,其流程相同,如图7所示,首先检查当前WIFI HotSpot或P2P的状态,若为开启,则继续判断当前使用信道是否为5G Hz;若没有开启,则结束流程;若当前使用信道为5G Hz时,关闭5GHz信道,启动2.4GHz信道;若当前使用信道不为5G Hz时,则结束流程。
另一方面,优选地,当移动终端进入LTE-U去激活状态时,所述步骤S100具体包括:
S121、当移动终端进入LTE-U去激活状态,通过空口消息RRC连接重配置告知移动终端调制解调器,去激活当前的LTE-U作为辅小区;
S122、移动终端调制解调器利用移动终端BP和AP通信机制,将辅小区的状态变化消息传送到移动终端应用层。
优选地,,所述步骤S200具体包括:
S221、移动终端应用层接收所述状态变化消息,将第一系统参数和第二系统参数的参数值设置为假,将WIFI可用信道列表设置成2.4GHz和5GHz,控制5G Hz信道开启。
具体来说,请参阅图8,图8为本发明提供的移动终端LTE-U与WIFI5G信道共存的自干扰解决方法进入去激活状态的实现流程图,图8为进入LTE-U去激活的实现流程,终端软件对于WIFI可用信道的控制。同样,网络侧通过空口消息RRC Connection Reconfiguration告知Modem,去激活当前的LTE-U辅小区;Appplication收到来自Modem侧的状态变化消息,其中cell_state字段值为false,则Application层先将两个系统参数值设置为false。最后将WIFI可用信道列表设置成2.4GHz+5GHz。
在实际应用时,当前已开启的AP/P2P服务仍然保持之前的信道使用情况。但WIFI Hotspot(热点)服务,用户可以再次自主选择特定信道5GHz或2.4GHz;对于WIFI P2P服务来说,后续的再使用(使能开完关闭再开启)将会按照默认设计,优先选择5GHz信道。另外,当移动终端开机驻留在非LTE-U的普通网络,则无RRC Connection Reconfiguration,携带sCellToAddModList的LTE-U状态消息的上报。在该情况下去开启WIFI热点或P2P,Application(应用层)读取到的系统参数值为false,Hotspot允许用户对信道的选择,P2P默认设计优选选择5GHz。这个与终端的默认行为一样,因此未在图中显示。
请参阅图9,图9为本发明提供的移动终端LTE-U与WIFI5G信道共存的自干扰解决方法第一应用实施例的场景示意图,本发明提供的移动终端LTE-U与WIFI5G信道共存的自干扰解决方法,应用到现实用户环境和网络中,主要有两种场景,如图9所示,为其中的一种。LTE network为LTE网络覆盖范围(LTE小区),而LTE-U CELL为LTE-U覆盖范围(LTE-U小区),图9中LTE-U范围内所示为移动终端,譬如手机。场景1中手机同时处于LTE网络和LTE-U小区覆盖范围内,此时开机注册LTE到网络后,通过空口RRC重配消息成功激活下行载波的LTE-U作为辅小区。在该情况下,当终端打开WIFI热点或者WIFI P2P功能,由于可用信道只有2.4GHz,工作信道在2.4GHz上,对外提供WIFI AP/P2P服务,如图9应用场景1所示;若用户之前已经打开了WIFI AP/P2P服务并工作在5GHz信道上,则会由于WIFI信道使用的检查流程而被强制切换到2.4GHz。
请参阅图10,图10为本发明提供的移动终端LTE-U与WIFI5G信道共存的自干扰解决方法第二应用实施例的场景示意图,另一种场景2为移动手机所处位置,从而离开LTE-U覆盖范围,这样便可引起状态变化。场景2中,手机驻留在同一LTE小区,但移动离开了LTE-U网络覆盖范围,空口RRC重配消 息将会去激LTE-U辅小区。在该情况下,手机将保持原有的WIFI AP/P2P工作频率,但在用户界面上的WIFI可用信道列表上添加2.4GHz+5GHz。
从上述两个场景来讲,本发明提出的技术方案,在LTE-U处于激活状态时关闭WIFI 5GHz信道,在LTE-U处于去激活状态时开启WIFI 5GHz信道,从而在软件层面上实现了在移动终端上错开对5GHz信道使用时间,较好地避开了自干扰问题,使得终端用户既能良好享用LTE-U网络带来的高速率,又保证了自身WIFI热点和P2P对外的正常使用。
