Description

一种控制面配置方法和网络设备Control plane configuration method and network device 技术领域Technical field
本发明涉及无线通信技术，尤其涉及一种控制面配置方法和网络设备。The present invention relates to wireless communication technologies, and in particular, to a control plane configuration method and a network device.
背景技术Background technique
移动互联网、物联网、以及其他业务应用的迅猛发展已经成为推动第五代移动通信技术(5G)发展的主要驱动力。他们迫切要求5G具有媲美光纤的接入速率、千亿设备的连接能力、完美的实时体验、以及随时随地的无线宽带接入能力。此外，能耗效率、频谱效率和峰值速率等重要指标也需要在5G***设计时综合考虑。中国在2013年就已经成立了IMT-2020(5G)推进组来推动5G技术的发展。根据国际整体情况，预计2015年将形成5G愿景、关键能力需求、及频谱规划；之后将启动5G标准化工作，计划在2020年后开始商用。国际标准方面，LTE-Advanced的技术标准主要是在3GPP国际标准化组织制订。业界初步认为在3GPP R14阶段(预计于2016年)将启动面向5G的标准研究工作。The rapid development of mobile Internet, Internet of Things, and other business applications has become the main driving force for the development of the fifth generation of mobile communication technology (5G). They are eager to demand 5G's access rate comparable to fiber optics, connectivity to billions of devices, a perfect real-time experience, and wireless broadband access anywhere, anytime. In addition, important indicators such as energy efficiency, spectrum efficiency and peak rate also need to be considered in the design of 5G systems. China has established the IMT-2020 (5G) promotion group in 2013 to promote the development of 5G technology. According to the overall situation of the international community, it is expected that a 5G vision, key capability needs, and spectrum planning will be formed in 2015; 5G standardization will be launched afterwards, and it is planned to start commercialization after 2020. In terms of international standards, the technical standards of LTE-Advanced are mainly formulated by the 3GPP International Organization for Standardization. The industry initially believes that standard research work for 5G will be initiated in the 3GPP R14 phase (expected in 2016).
在未来的移动网络中，业务量需求会不断提高、终端数目和种类也不断爆发式增长、用户QOS等需求差异化明显，这些都需要我们针对不同场景研究对应的解决方案。随着未来5G无线网络的发展和无线宽带应用的普及，重叠覆盖的场景将会越来越多。例如用于增强容量的宏站覆盖下的超密集网络，以及宏站覆盖下的移动中继网络等。随着用户的移动，他可能经历不同的重叠覆盖的网络场景。这些场景中，不同覆盖所提供的无线链路的质量和特性也大不相同。例如，在5G的典型场景超密集网络(UDN)中，宏站提供的无线链路支持范围大，但由于距离较远的原因信道质量可能不是很好。相反的，UDN小站虽然能够提供好的链路质量，但由于小站的覆盖很小，无法很好的支持用户的快速移动。同样的情况也发生在游牧网络以及移动中继网络的场景中。 In the future mobile network, the demand for business will continue to increase, the number and types of terminals will continue to grow exponentially, and the demand for user QOS will be differentiated. These require us to study the corresponding solutions for different scenarios. With the development of 5G wireless networks and the popularity of wireless broadband applications in the future, there will be more and more overlapping coverage scenarios. For example, an ultra-dense network covered by a macro station for enhancing capacity, and a mobile relay network covered by a macro station. As the user moves, he may experience different overlapping coverage of the network scene. In these scenarios, the quality and characteristics of the wireless links provided by different coverages are also very different. For example, in a 5G typical scene super dense network (UDN), the macro station provides a wide range of radio link support, but the channel quality may not be very good due to the long distance. On the contrary, although the UDN station can provide good link quality, the small station has very small coverage and cannot support the user's fast movement. The same thing happens in nomadic networks and mobile relay networks.

In this way, not only the various wireless coverages are fully utilized, but also the control plane overhead is reduced; and the inadequacies of the various coverage links can be compensated for, thereby providing users with better service quality. For example, high-speed users in UND can use macro cells for control, and low-speed or stationary users can control with small cells. In this way, the high-quality link resources provided by the small cell coverage are fully utilized, and the small cell coverage is small, and the high-speed users are likely to cause rapid and frequent switching. In extreme cases, for low-speed users, when the macro coverage provides only the QPSK, and the small cell coverage can support 64QAM, the small cell coverage can save 2/3 signaling overhead.

本发明的实施方式Embodiments of the invention
下文将结合附图对本发明的实施方式作详细说明。需要说明的是，在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments of the present application may be combined with each other arbitrarily.
实施例1Example 1
由于，在无线通信***设计中，控制面的设计是一个很重要的问题。通常情况下，用于控制的信道要求具有稳定可靠的特性，并要在支持正常功能的前提下尽量减少控制信令传递的开销。所以在未来的5G网络中，如果能根据用户所处的场景和覆盖所提供的无线链路的特性进行灵活的控制面配置，必然能够提供更加稳定可靠的控制效果，减少信令的开销。Because of the design of the wireless communication system, the design of the control surface is an important issue. Normally, the channel used for control is required to have stable and reliable characteristics, and the overhead of control signaling transmission should be minimized while supporting normal functions. Therefore, in the future 5G network, if the flexible control plane configuration can be configured according to the scenario of the user and the characteristics of the wireless link provided by the coverage, it is possible to provide a more stable and reliable control effect and reduce the signaling overhead.
本实施例提供一种控制面配置方法，使用户能根据所处的场景以及覆盖所提供的无线链路的特性进行灵活的控制面配置，在加强控制面的稳定性和可靠性，减少信令的开销。该方法主要包括如下操作：The embodiment provides a control plane configuration method, so that the user can perform flexible control plane configuration according to the scenario and the characteristics of the provided wireless link, and strengthen the stability and reliability of the control plane, and reduce signaling. s expenses. The method mainly includes the following operations:
网络侧获取终端设备所处场景信息，根据终端设备所处场景信息对该终端设备进行控制面的配置；Obtaining, by the network side, the scenario information of the terminal device, and configuring the control device according to the scenario information of the terminal device;
所述网络侧将控制面的配置信息发送给所述终端设备。The network side sends configuration information of the control plane to the terminal device.
本实施例中所涉及的终端设备所处场景信息包括终端设备当前的覆盖场景信息，可以包括覆盖数量和每个覆盖的特性。例如，所支持的通信范围，每个覆盖无线链路的质量(或SINR)等。The scenario information of the terminal device involved in this embodiment includes current coverage scenario information of the terminal device, and may include a coverage quantity and a feature of each coverage. For example, the supported communication range, the quality (or SINR) of each coverage wireless link, and the like.
一些UE可能只有宏覆盖；一些UE除了宏覆盖，还处于车上，所以还有 车上的relay覆盖。而车辆又可能行驶到UDN重叠覆盖区，这时又增加了UDN覆盖等等。而不同覆盖场景又具有不同特性，例如无线链路的范围和SINR各不相同等。因此，可根据覆盖场景的不同特性进行相应的控制面的配置。Some UEs may only have macro coverage; some UEs are in the car except macro coverage, so there are The relay overlay on the car. The vehicle may travel to the UDN overlapping coverage area, and then add UDN coverage and so on. Different coverage scenarios have different characteristics, such as the range of the wireless link and the SINR are different. Therefore, the configuration of the corresponding control surface can be performed according to different characteristics of the coverage scene.
其中，终端设备本地与场景感知有关的信息包括如下一种或几种信息：The local information related to the scene sensing of the terminal device includes one or more of the following information:
GPS信息、用户的移动速度、所测各个覆盖的无线信道的信息、用户本地业务信息。GPS information, user's moving speed, information of each covered wireless channel measured, and user local service information.
网络侧的场景感知辅助信息包括如下一种或几种：The scene-aware auxiliary information on the network side includes one or more of the following:
宏站及下属各发射点的类型、宏站及下属各发射点的相关信息、邻/本小区负荷信息。The type of the macro station and its subordinate transmission points, the related information of the macro station and the subordinate transmission points, and the neighbor/local cell load information.
其中，网络侧对终端设备进行控制面的配置指：网络侧对终端设备针对不同的控制面消息配置一个或多个传输信道，其中，配置多个传输信道时，所配置的传输信道属于相同或不同的覆盖。The configuration of the control plane of the terminal device on the network side means that the network side configures one or more transport channels for different control plane messages for the terminal device, wherein when multiple transport channels are configured, the configured transport channels belong to the same or Different coverage.
控制面配置方式可以是独立的，交叉的，或重叠的。在独立的控制面配置方式中，用户只通过一个覆盖所提供的无线链路进行控制面消息的传递。在交叉的控制面配置方式中，用户的控制面消息可以在两个或多个覆盖所提供的两个或多个无线链路中分别进行传递。例如，可以一部分控制消息通过一个覆盖所提供的无线链路进行传递，另一部分控制消息是通过另一个覆盖所提供的无线链路进行传递。而在重叠的控制面配置方式中，用户的控制面消息是同时在两个或多个覆盖所提供的两个或多个无线链路中进行传递的。这种重叠的配置方式下，每个消息都被重复传递了多次，有利于增强信令传递的可靠性。Control plane configurations can be independent, crossed, or overlapping. In the independent control plane configuration mode, the user only transmits the control plane message through one of the provided wireless links. In the cross-control plane configuration, the user's control plane messages can be delivered separately in two or more wireless links provided by two or more overlays. For example, a portion of the control message may be communicated over a wireless link provided by an overlay, and another portion of the control message may be delivered over a wireless link provided by another overlay. In the overlapping control plane configuration mode, the user's control plane message is simultaneously transmitted in two or more wireless links provided by two or more overlays. In this overlapping configuration mode, each message is repeatedly transmitted multiple times, which is beneficial to enhance the reliability of signaling transmission.
对于交叉的控制面配置方式，本实施例提出可以定义几种不同的控制面交叉配置模式，由网络按实际需要根据场景感知的结果选择决定后通知给用户。这样网络只需要通知用户一个交叉模式，而不用传递控制面交叉配置状况，大大减少了相关的信令开销，并能支持多种不同的控制面交叉配置方式。For the configuration of the intersecting control planes, this embodiment proposes that several different control plane cross configuration modes can be defined, and the network notifies the user according to the actual needs according to the result of the scene sensing. In this way, the network only needs to notify the user of a cross mode, instead of transmitting the control plane cross configuration status, greatly reducing the related signaling overhead, and can support multiple different control plane cross configuration modes.
在交叉的控制面配置方式中，可以利用大覆盖的宏站进行大尺度的控制，而利用小覆盖的小站、中继站、或游牧网络的簇头等进行小尺度的控制。这里，大尺度的控制包括但不限于：大的资源块分配，大的资源请求，用户移动性管理等；小尺度的控制包括但不限于：小资源块分配，小块资源请求，MCS等链路级发送方式的控制，ACK/NACK消息等。 In the cross-control plane configuration mode, large-scale macro stations can be used for large-scale control, and small-scale small stations, relay stations, or cluster heads of nomadic networks can be used for small-scale control. Here, large-scale control includes but is not limited to: large resource block allocation, large resource request, user mobility management, etc.; small-scale control includes but is not limited to: small resource block allocation, small resource request, MCS, etc. Control of the way of sending the road level, ACK/NACK message, etc.
在交叉的控制面配置方式中，也可以利用大覆盖的宏站来指示小覆盖的小站、中继站、或游牧网络的簇头等所采用的控制策略，控制方式，以及相关的控制信道名称、类型、所占资源位置等。In the cross-control plane configuration mode, the macro-overlay macro station can also be used to indicate the control strategy, control mode, and related control channel name and type used by small-small stations, relay stations, or cluster heads of nomadic networks. , the location of the resources, and so on.
网络侧可以通过控制面配置通知消息将控制面的配置信息发送给终端设备。可选地，控制面配置通知消息包含用于指示采用该消息中指示的控制面配置的起始时间信息。The network side can send the configuration information of the control plane to the terminal device through the control plane configuration notification message. Optionally, the control plane configuration notification message includes start time information indicating that the control plane configuration indicated in the message is employed.
还要说明的是，上述方法中，网络侧获取终端设备所处场景信息的方式有多种多样，本实施例不作具体限制。例如：网络侧可以直接接收终端设备上报的终端设备所处场景的信息。或者，网络侧接收终端设备上报的终端设备本地与场景感知有关的信息，根据终端设备本地与场景感知有关的信息，或者根据终端设备本地与场景感知有关的信息结合网络侧的场景感知辅助信息获取终端设备所处场景信息。It should be noted that, in the above method, the manner in which the network side obtains the scene information of the terminal device is various, and is not specifically limited in this embodiment. For example, the network side can directly receive information about the scene where the terminal device is reported by the terminal device. Or, the network side receives the local information related to the scene sensing of the terminal device reported by the terminal device, and according to the information related to the scene sensing locally by the terminal device, or according to the local information related to the scene sensing of the terminal device, and the context-aware auxiliary information acquisition on the network side. The scene information of the terminal device.
当网络侧直接接收终端设备上报的终端设备所处场景的信息时，网络侧可以通过广播信道或专用用户控制信道通知终端设备上报终端设备本地与场景感知有关的信息。而收到通知的终端设备侧，则进行如下操作：When the network side directly receives the information about the scene in which the terminal device is located, the network side can notify the terminal device to report the local information related to the scene perception by the terminal device through the broadcast channel or the dedicated user control channel. On the terminal device side that receives the notification, proceed as follows:
终端设备根据本地与场景感知有关的信息，或者根据本地与场景感知有关的信息结合网络侧下发的场景感知辅助信息判断本终端设备所处场景，并将所判断的场景信息上报给网络侧。The terminal device determines the scenario in which the terminal device is located according to the local information related to the scenario, or the scenario-aware information that is sent by the network side, and reports the scenario information to the network side.
下面结合附图对上述方法作进一步详细说明。The above method will be further described in detail below with reference to the accompanying drawings.
图1描述了应用场景。随着未来5G无线网络的发展和无线宽带应用的普及，重叠覆盖的场景将会越来越多。例如用于增强容量的宏站覆盖下的超密集网络，以及宏站覆盖下的移动中继网络等。随着用户的移动，他可能经历不同的重叠覆盖的网络场景。这些场景中，不同覆盖所提供的无线链路的质量和特性也大不相同。例如，在5G的典型场景超密集网络(UDN)中，宏站提供的无线链路支持范围大，但由于距离较远的原因信道质量可能不是很好。相反的，UDN小站虽然能够提供好的链路质量，但由于小站的覆盖很小，无法很好的支持用户的移动。同样的情况也发生在游牧网络以及移动中继网络的场景中。 Figure 1 depicts the application scenario. With the development of 5G wireless networks and the popularity of wireless broadband applications in the future, there will be more and more overlapping coverage scenarios. For example, an ultra-dense network covered by a macro station for enhancing capacity, and a mobile relay network covered by a macro station. As the user moves, he may experience different overlapping coverage of the network scene. In these scenarios, the quality and characteristics of the wireless links provided by different coverages are also very different. For example, in a 5G typical scene super dense network (UDN), the macro station provides a wide range of radio link support, but the channel quality may not be very good due to the long distance. On the contrary, although the UDN station can provide good link quality, the coverage of the small station is small, and the user's movement cannot be well supported. The same thing happens in nomadic networks and mobile relay networks.
图2为用户侧场景感知的控制面配置方法流程示意图，具体包括如下步骤：FIG. 2 is a schematic flowchart of a control plane configuration method for sensing a scene on a user side, which specifically includes the following steps:
步骤201，用户直接进行场景感知和判断。In step 201, the user directly performs scene sensing and judgment.
其中，该场景感知和判断行为可以基于用户在本地直接获取的各种信息，例如GPS信息、用户的移动速度、所测各个覆盖的无线信道的信息、用户本地业务信息等；也可以基于用户从网络侧收到的各种辅助信息。The scene sensing and determining behavior may be based on various information directly acquired by the user locally, such as GPS information, a user's moving speed, information of each covered wireless channel measured, user local service information, etc.; Various auxiliary information received by the network side.
可选的，无线网络可以广播各种网络侧的有关信息来帮助用户进行场景感知。这些信息包括但不限于：宏站及下属各发射点的类型(例如可能是UDN小站、中继点、移动中继点、移动网络簇头等)、宏站及下属各发射点的相关信息(例如相关的发现信号，负荷情况，同步要求等)、邻/本小区负荷信息等。Optionally, the wireless network can broadcast related information on various network sides to help the user to perform scene sensing. The information includes, but is not limited to, the types of macro stations and subordinate transmission points (for example, may be UDN stations, relay points, mobile relay points, mobile network cluster heads, etc.), macro stations, and subordinate transmission points ( For example, related discovery signals, load conditions, synchronization requirements, etc.), neighbor/local cell load information, and the like.
步骤202，用户向网络报告相关的场景信息。In step 202, the user reports related scene information to the network.
可选的，用户可以根据本地场景判断的结果直接选择一个覆盖所提供的链路建立一个独立运行的控制面。这种情况下，用户无需向网络进行场景报告，也无需进行后续步骤。Optionally, the user can directly select an overlay to provide an independently running control plane according to the result of the local scenario judgment. In this case, the user does not need to report the scenario to the network, and no subsequent steps are required.
步骤203，网络根据用户报告的场景信息对用户进行具体的控制面配置，并将相关的配置信息通过‘控制面配置通知’消息传递给用户。然后用户按网络通知的配置方式进行控制面消息的传递。Step 203: The network performs specific control plane configuration on the user according to the scenario information reported by the user, and transmits related configuration information to the user by using a “control plane configuration notification” message. Then the user delivers the control plane message according to the configuration mode of the network notification.
可选的，‘控制面配置通知’消息中可以包含一个起始时间信息用于指示采用其中的控制面配置的起始时间。Optionally, the 'Control Plane Configuration Notification' message may include a start time information indicating the start time of the control plane configuration in which it is employed.
从以上步骤不难看出，本申请所述的基于用户侧场景感知的控制面配置方法中的控制面的配置方式既可以由用户在本地直接决定，也可以由网络决定后通知该用户。相关的信令消息，包括但不限于场景报告和控制面配置通知等，既可以利用此前已经建立的控制面进行传递，也可以通过初始接入或其他过程进行传递，还可以通过其他专用信道进行传递。It is not difficult to see from the above steps that the configuration of the control plane in the control plane configuration method based on the user-side scene sensing described in the present application may be directly determined by the user locally, or may be notified by the network. Relevant signaling messages, including but not limited to scenario reports and control plane configuration notifications, can be transmitted using previously established control planes, through initial access or other processes, or through other dedicated channels. transfer.
图3为本实施例提供的网络侧场景感知的控制面配置方法流程示意图，包括如下步骤：FIG. 3 is a schematic flowchart of a method for configuring a control plane configured on a network side according to the embodiment, which includes the following steps:
步骤301，用户进行场景感知有关的测量和信息收集，所述信息包括但 不限于：GPS信息、用户的移动速度、所测各个覆盖的无线信道的信息、用户的本地业务信息等。Step 301: The user performs scene sensing related measurement and information collection, where the information includes It is not limited to: GPS information, user's moving speed, information of each covered wireless channel measured, local service information of the user, and the like.
可选的，该信息测量和收集过程可以在网络的指导下进行。这种情况下，无线网络应该通知用户进行场景感知所需要关注的信息类型。该通知既可以通过广播信道提供给一组用户，也可以通过此前已经建立的专用用户控制信道通知给某个特定用户。Optionally, the information measurement and collection process can be performed under the guidance of the network. In this case, the wireless network should inform the user of the type of information that needs to be focused on for scene awareness. The notification can be provided to a group of users through a broadcast channel, or can be notified to a specific user through a dedicated user control channel that has been previously established.
步骤302，用户向网络报告场景感知有关的信息。In step 302, the user reports information related to the scene perception to the network.
该报告既可以利用此前已经建立的控制信道传递，也可以通过初始接入或其他过程进行传递。可选的，用户可以基于网络所提供的信息有选择的报告有关信息，或对有关信息进行综合后再进行报告。The report can be delivered using either the previously established control channel or through initial access or other processes. Optionally, the user can selectively report related information based on information provided by the network, or synthesize the related information before reporting.
步骤303，网络基于用户报告的信息进行用户场景判决，并根据所判断的场景对用户进行具体的控制面配置。最后将相关的配置信息通过‘控制面配置通知’消息传递给用户。此后，用户按网络通知的配置方式进行控制面消息的传递。Step 303: The network performs user scenario determination based on the information reported by the user, and performs specific control plane configuration on the user according to the determined scenario. Finally, the relevant configuration information is delivered to the user through the 'Control Plane Configuration Notification' message. Thereafter, the user transmits the control plane message according to the configuration mode of the network notification.
可选的，也可以结合网络本身所能获得的各种网络侧信息进行场景判决。所述网络侧信息包括但不限于：宏站及下属发射点的类型(例如可能是UDN小站、中继点、移动中继点、移动网络簇头等)、宏站及下属各发射点的相关信息(例如相关的发现信号，负荷情况，同步要求等)、邻/本小区负荷信息等。可选的，‘控制面配置通知’消息中可以包含一个起始时间信息用于指示采用其中的控制面配置的起始时间。Optionally, the scenario determination may also be performed by combining various network side information that can be obtained by the network itself. The network side information includes, but is not limited to, a type of a macro station and a subordinate transmission point (for example, may be a UDN small station, a relay point, a mobile relay point, a mobile network cluster head, etc.), a macro station, and a subordinate transmission point correlation. Information (such as related discovery signals, load conditions, synchronization requirements, etc.), neighbor/local cell load information, and the like. Optionally, the 'Control Plane Configuration Notification' message may include a start time information indicating the start time of the control plane configuration in which it is employed.
本实施例涉及的控制面配置方式可以是独立的，交叉的，或重叠的，不做具体限制。The control plane configuration manners in this embodiment may be independent, intersecting, or overlapping, and are not specifically limited.
下面以UDN重叠覆盖场景为例进行说明。需要注意的是，本申请包括但不限于UDN场景。图4为本实施例提供的独立的控制面配置方法示意图。在独立的控制面配置方式中，用户只通过一个覆盖所提供的无线链路进行控制面消息的传递。The UDN overlap coverage scenario is taken as an example for description. It should be noted that the application includes, but is not limited to, a UDN scenario. FIG. 4 is a schematic diagram of a method for configuring an independent control plane according to the embodiment. In the independent control plane configuration mode, the user only transmits the control plane message through one of the provided wireless links.
图5为本实施例提供的交叉的控制面配置方法示意图。在交叉的控制面配置方式中，用户的控制面消息可以在两个或多个覆盖所提供的两个或多个 无线链路中分别进行传递。例如，可以一部分控制消息通过一个覆盖所提供的无线链路进行传递，另一部分控制消息是通过另一个覆盖所提供的无线链路进行传递。需要注意的是交叉的控制面配置方式中控制面消息只进行一次传递，这次传递根据具体的控制面配置发生在其中一个覆盖所提供的无线链路中。对于交叉的控制面配置方式，本实施例提出可以规定几种不同的控制面交叉配置模式，由网络按实际需要根据场景感知的结果选择决定后通知给用户。这样网络只需要通知用户一个交叉模式，而不用传递具体的控制面交叉配置状况，大大减少了相关的信令开销，并能支持多种不同的控制面交叉配置方式。FIG. 5 is a schematic diagram of a method for configuring an intersecting control plane according to an embodiment of the present invention. In the cross-control plane configuration mode, the user's control plane message can be provided in two or more of two or more coverages. The transmission is performed separately in the wireless link. For example, a portion of the control message may be communicated over a wireless link provided by an overlay, and another portion of the control message may be delivered over a wireless link provided by another overlay. It should be noted that the control plane message is only transmitted once in the cross-control plane configuration mode. This transmission occurs in the wireless link provided by one of the coverages according to the specific control plane configuration. For the configuration of the intersecting control planes, this embodiment proposes that several different control plane cross configuration modes can be specified, and the network notifies the user according to the actual needs according to the result of the scene sensing. In this way, the network only needs to notify the user of a cross mode, instead of transmitting a specific control plane cross configuration condition, which greatly reduces the related signaling overhead and can support multiple different control plane cross configuration modes.
在交叉的控制面配置方式中，可以利用大覆盖的宏站进行大尺度的控制，而利用小覆盖的小站、中继站、或游牧网络的簇头等进行小尺度的控制。这里，大尺度的控制包括但不限于：大的资源块分配，大的资源请求，用户移动性管理等；小尺度的控制包括但不限于：小资源块分配，小块资源请求，MCS等链路级发送方式的控制，ACK/NACK消息等。In the cross-control plane configuration mode, large-scale macro stations can be used for large-scale control, and small-scale small stations, relay stations, or cluster heads of nomadic networks can be used for small-scale control. Here, large-scale control includes but is not limited to: large resource block allocation, large resource request, user mobility management, etc.; small-scale control includes but is not limited to: small resource block allocation, small resource request, MCS, etc. Control of the way of sending the road level, ACK/NACK message, etc.
在交叉的控制面配置方式中，也可以利用大覆盖的宏站来指示小覆盖的小站、中继站、或游牧网络的簇头等所采用的控制策略，控制方式，以及相关的控制信道名称、类型、所占资源位置等。In the cross-control plane configuration mode, the macro-overlay macro station can also be used to indicate the control strategy, control mode, and related control channel name and type used by small-small stations, relay stations, or cluster heads of nomadic networks. , the location of the resources, and so on.
图6为本实施例提供的重叠的控制面配置方法示意图。在重叠的控制面配置方式中，用户的控制面消息是同时在两个或多个覆盖所提供的两个或多个无线链路中进行传递的。这种重叠的配置方式下，每个消息都被重复传递了多次，有利于增强信令传递的可靠性。FIG. 6 is a schematic diagram of a method for configuring an overlapping control plane according to an embodiment of the present invention. In an overlapping control plane configuration, the user's control plane message is delivered simultaneously in two or more wireless links provided by two or more overlays. In this overlapping configuration mode, each message is repeatedly transmitted multiple times, which is beneficial to enhance the reliability of signaling transmission.
