Description

一种非授权载波的测量方法及装置Method and device for measuring unlicensed carrier 技术领域Technical field
本文涉及但不限于通信领域中的非授权载波技术，尤其涉及一种非授权载波的测量方法及装置。This document relates to, but is not limited to, unlicensed carrier technology in the field of communications, and in particular to a method and apparatus for measuring unlicensed carriers.
背景技术Background technique
在移动通信***中，小区重选和切换是其重要的功能。为了顺利实现小区重选，终端(UE，User Equipment)需要对不同小区的信号质量进行测量，以便选择合适的小区进行驻留。当UE在某个小区与网络建立连接之后，UE仍然需要对其相邻小区的信号质量进行测量，以便选择合适的小区进行切换，满足移动性要求。In mobile communication systems, cell reselection and handover are important functions. In order to successfully implement cell reselection, the terminal (UE, User Equipment) needs to measure the signal quality of different cells in order to select a suitable cell to camp. After the UE establishes a connection with the network in a certain cell, the UE still needs to measure the signal quality of its neighboring cell, so as to select a suitable cell for handover to meet the mobility requirement.
长期演进(LTE，Long Term Evolution)***中，UE在连接态下测量小区信号质量的过程包括：网络侧将测量控制消息发送给UE，其中，该测量控制消息中包括测量标识、测量对象、报告配置以及测量的其他相关属性。测量对象包含了测量对象属性，如载频，邻区列表等；报告配置包含了报告配置属性，如事件触发或周期上报，触发的事件定义(A1、A2…)，上报次数等。UE根据测量控制消息中的测量对象、报告配置去执行测量和评估，并根据测量结果生成测量报告上报给网络侧。对于事件触发的测量任务，当测量对象满足事件的准入条件，如测量对象信号质量优于门限的持续时间大于或等于触发时间(TTT，Time To Trigger)时才被认为是满足事件触发条件的测量对象。当有测量对象满足事件的触发条件后，上报测量报告给网络侧。In the LTE (Long Term Evolution) system, the UE measures the cell signal quality in the connected state, and the network side sends the measurement control message to the UE, where the measurement control message includes the measurement identifier, the measurement object, and the report. Configuration and other related properties of the measurement. The measurement object contains measurement object attributes, such as carrier frequency, neighbor list, etc. The report configuration includes report configuration attributes, such as event trigger or periodic report, triggered event definition (A1, A2...), and number of reports. The UE performs measurement and evaluation according to the measurement object and the report configuration in the measurement control message, and generates a measurement report according to the measurement result and reports it to the network side. For an event-triggered measurement task, when the measurement object satisfies the event entry condition, such as when the measurement object signal quality is better than the threshold duration is greater than or equal to the trigger time (TTT, Time To Trigger), it is considered to satisfy the event trigger condition. Measuring object. After the measurement object satisfies the trigger condition of the event, the measurement report is reported to the network side.
为了向移动用户提供更高的数据速率，高级长期演进***(LTE-A，Long Term Evolution Advance)提出了载波聚合技术(CA，Carrier Aggregation)，其目的是为具有相应能力的UE提供更大宽带，提高UE的峰值速率。LTE中，***支持的最大下行传输带宽为20MHz，载波聚合是将两个或者更多的分量载波(CC，Component Carriers)聚合起来支持大于20MHz，且不超过100MHz的传输带宽。引入载波聚合技术后，处于连接状态的UE可以同时通 过多个CC与源基站进行通信，引入CA技术后，还引入了主服务小区(Pcell，Primary Cell)和辅服务小区(Scell，Secondary Cell)。In order to provide mobile users with higher data rates, the Long Term Evolution (LTE-A) system proposes Carrier Aggregation (CA), which aims to provide greater bandwidth for UEs with corresponding capabilities. To increase the peak rate of the UE. In LTE, the maximum downlink transmission bandwidth supported by the system is 20 MHz. Carrier aggregation is to aggregate two or more component carriers (CCs) to support a transmission bandwidth greater than 20 MHz and not exceeding 100 MHz. After the carrier aggregation technology is introduced, the UE in the connected state can simultaneously pass. A plurality of CCs communicate with the source base station, and after the introduction of the CA technology, a primary serving cell (Pcell, Primary Cell) and a secondary serving cell (Scell, Secondary Cell) are also introduced.
由于频谱资源的匮乏，以及移动用户的大流量业务的激增，采用高频点如3.5GHz进行热点覆盖的需求日益明显，采用低功率的节点成为新的应用场景，为的是增加用户吞吐量和增强移动性能。但是，由于高频点的信号衰减比较厉害，小区的覆盖范围比较小，并且与现有的小区不共站点，目前不少公司和运营商都倾向于寻求一种新的增强方案，双连接(DC，Dual Connectivity)就是其中之一。双连接下终端可以同时与两个以上的网络节点保持连接，但是控制面连接只与其中一个小区比如宏小区有连接。终端的多个服务节点是多个基站，基站之间的时延不可忽略。比如，一个网络节点是宏基站称为主基站(MeNB，Master evolved Node B)，另外一个网络节点是小小区基站称为辅基站(SeNB，Secondary evolved Node B)。Due to the lack of spectrum resources and the proliferation of mobile users' large-traffic services, the need for hotspot coverage using high-frequency points such as 3.5 GHz is becoming increasingly apparent, and the adoption of low-power nodes becomes a new application scenario in order to increase user throughput and Enhance mobile performance. However, due to the relatively high signal attenuation at high frequency points, the coverage of the cell is relatively small, and the existing cells do not share the site. At present, many companies and operators tend to seek a new enhanced solution, dual connectivity (DC). , Dual Connectivity) is one of them. A dual-connected terminal can remain connected to more than two network nodes at the same time, but the control plane connection is only connected to one of the cells, such as a macro cell. The multiple service nodes of the terminal are multiple base stations, and the delay between the base stations is not negligible. For example, one network node is a macro base station called a primary evolved Node B (MeNB), and the other network node is a small cell base station called a secondary evolved Node B (SeNB).
随着数据业务的快速增长，在不久的将来，授权频谱将不能承受如此巨大的数据量；所以LTE运营商考虑在非授权频谱(Unlicensed Carrier)资源中部署LTE，通过非授权频谱来分担授权载波中的数据流量。非授权载波(免授权频谱)是指在满足政府部门(如，国家无线电管理委员会)有关规定(无线电管制)下，不需要授权就能直接使用的频谱(或载波)。例如，微波炉、遥控玩具飞机、无线鼠标、无线键盘、高保真无线上网(WiFi，Wireless Fidelity)等都使用了非授权载波。有的情况下，非授权载波需要通过竞争才能使用。如果基站(包括WiFi接入点)没有竞争到资源，则不能使用非授权载波。非授权载波和授权载波可以通过载波聚合的方式使用，也可以通过双连接的方式使用，非授权载波一般作为数据传输的补充，即授权载波作为主服务小区，非授权载波作为辅服务小区。With the rapid growth of data services, the licensed spectrum will not be able to withstand such a huge amount of data in the near future; therefore, LTE operators consider deploying LTE in unlicensed carrier resources and sharing licensed carriers through unlicensed spectrum. Data traffic in . Unlicensed carrier (exempted spectrum) refers to the spectrum (or carrier) that can be used directly without authorization, subject to the relevant regulations (radio control) of government agencies (eg, National Radio Regulatory Commission). For example, microwave ovens, remote-controlled toy airplanes, wireless mice, wireless keyboards, wireless fidelity (WiFi), etc. all use unlicensed carriers. In some cases, unlicensed carriers need to compete to be used. If the base station (including the WiFi access point) does not compete for resources, the unlicensed carrier cannot be used. The unlicensed carrier and the authorized carrier may be used in a carrier aggregation manner or in a dual connectivity manner. The unlicensed carrier is generally used as a supplement to the data transmission, that is, the authorized carrier is used as the primary serving cell, and the unlicensed carrier is used as the secondary serving cell.
非授权载波资源有很大的特殊性，在此场景下，需要终端上报接收的信号强度指示(RSSI，Received Signal Strength Indication)及其高于指定门限的百分比，目的是为了获得频率的整体负荷情况，为了让基站获得终端侧的干扰情况，另外一点，也为基站做频率选择做依据，并对发现隐藏节点(hidden node)有帮助。但是，如何上报RSSI以及如何使用RSSI进行资源管理，尚未有较好的解决方案。以下未经特殊说明，RSSI都是平均的RSSI。 The unlicensed carrier resource has a special feature. In this scenario, the Received Signal Strength Indication (RSSI) and the percentage above the specified threshold are reported by the terminal. The purpose is to obtain the overall load of the frequency. In order to let the base station obtain the interference situation on the terminal side, another point is also to make the basis for the base station to select the frequency, and it is helpful to find the hidden node. However, there is no better solution to how to report RSSI and how to use RSSI for resource management. Unless otherwise specified, RSSI is the average RSSI.

图1为本发明实施例的非授权载波的测量方法的流程示意图，本示例中的非授权载波的测量方法应用于终端，如图1所示，所述非授权载波的测量方法包括以下步骤：FIG. 1 is a schematic flowchart of a method for measuring an unlicensed carrier according to an embodiment of the present invention. The method for measuring an unlicensed carrier in this example is applied to a terminal. As shown in FIG. 1 , the method for measuring an unlicensed carrier includes the following steps:
步骤101：接收基站发送的配置信息，所述配置信息为需要测量的RSSI的配置信息。Step 101: Receive configuration information sent by the base station, where the configuration information is configuration information of the RSSI that needs to be measured.
具体地，由终端接收基站发送的配置信息。Specifically, the terminal receives configuration information sent by the base station.

具体地，由终端根据所述配置信息，测量指定的RSSI。Specifically, the terminal measures the specified RSSI according to the configuration information.

第一种情况：当将非授权载波上的节点作为所述终端的服务节点时，在所述服务节点被所述终端占用时，测量网络环境的RSSI。The first case: when a node on an unlicensed carrier is used as a serving node of the terminal, the RSSI of the network environment is measured when the serving node is occupied by the terminal.

下面结合具体应用场景对本发明实施例的非授权载波的测量方法做进一步详细描述。The method for measuring an unlicensed carrier according to an embodiment of the present invention is further described in detail below with reference to a specific application scenario.
图2为本发明实施例场景示意图，授权辅助接入LAA的节点A(也即非授权载波上的节点A)，已经配置给终端作为服务节点，LAA的节点B(也即非授权载波上的节点B)，没有配置给终端作为服务节点。WiFi的节点C 是可见节点，LAA的节点D(也即非授权载波上的节点D)是hidden node，终端能测量到，但是基站无法测量到。WiFi的节点E是hidden node。2 is a schematic diagram of a scenario of an embodiment of the present invention. A node A that is authorized to access the LAA (that is, node A on an unlicensed carrier) is configured as a serving node, and a node B of the LAA (that is, on an unlicensed carrier). Node B) is not configured for the terminal as a service node. WiFi node C It is a visible node. The node D of the LAA (that is, the node D on the unlicensed carrier) is a hidden node, and the terminal can measure it, but the base station cannot measure it. Node E of WiFi is a hidden node.
基站有两块区域，一个区域为小区1(授权载波)，另一个区域为小区3(对应节点A)和小区4(对应节点B)，小区3和小区4是非授权载波，频点是f3，节点C、D和E的频点都是f3。节点F代表其他频点比如f4的LAA节点或WiFi节点。The base station has two areas, one area is cell 1 (authorized carrier), the other area is cell 3 (corresponding node A) and cell 4 (corresponding node B), cell 3 and cell 4 are unlicensed carriers, and the frequency point is f3. The frequency points of nodes C, D, and E are both f3. Node F represents a LAA node or a WiFi node of other frequency points such as f4.
实施例一：终端驻留在小区1上，并在小区1上发起无线资源控制(RRC，Radio Resource Control)连接建立，RRC连接建立过程完成后，UE进入连接态，小区1即为PCell。Embodiment 1: The terminal camps on the cell 1 and initiates a radio resource control (RRC) connection establishment on the cell 1. After the RRC connection establishment process is completed, the UE enters a connected state, and the cell 1 is a PCell.
参照图3，图3为本发明实施例一的非授权载波的测量方法的流程示意图，所述方法包括以下步骤：Referring to FIG. 3, FIG. 3 is a schematic flowchart of a method for measuring an unlicensed carrier according to Embodiment 1 of the present invention, where the method includes the following steps:
步骤301：由于业务的需要，基站需要给UE配置载波聚合，基站根据终端的测量报告将小区3(即节点A)配置给终端。Step 301: The base station needs to configure carrier aggregation for the UE, and the base station configures the cell 3 (ie, node A) to the terminal according to the measurement report of the terminal.
这里，小区3称为辅服务小区，小区3为非授权载波上的小区，需要先执行资源竞争过程，成功后才能正常收发数据。由于小区3被配置为终端的服务小区，因此节点A是服务节点。Here, the cell 3 is referred to as a secondary serving cell, and the cell 3 is a cell on the unlicensed carrier. The resource competition process needs to be performed first, and the data can be normally sent and received after successful. Since the cell 3 is configured as a serving cell of the terminal, the node A is a serving node.
步骤302：基站为了获得整体负荷情况，以及获得终端侧的干扰情况，给终端下发测量任务1，测量载频f3的RSSI；给终端下发测量任务2，测量载频f4的RSSI；下发测量任务3，测量载频f3上服务小区3的信号质量RSRP。Step 302: The base station sends the measurement task 1 to the terminal to measure the RSSI of the carrier frequency f3, and the measurement task 2 is sent to the terminal to measure the RSSI of the carrier frequency f4. Measurement task 3 measures the signal quality RSRP of the serving cell 3 on the carrier frequency f3.
下发测量任务1时，配置测量的时间周期和偏移，比如周期是40ms偏移是2；以及测量的时间长度，比如是6ms，或者这个测量时间长度固定不变，由协议规定。When the measurement task 1 is issued, the time period and offset of the measurement are configured, for example, the period is 40 ms offset is 2; and the measured time length, for example, 6 ms, or the measurement time length is fixed, as specified by the protocol.
下发测量任务2时，也给出测量的时间周期和偏移，比如周期是40ms偏移是3(f3和f4时间不对齐，为了使得测量时间对齐，可以通过偏移来纠正)；以及测量的时间长度，比如是6ms。When the measurement task 2 is issued, the time period and offset of the measurement are also given. For example, the period is 40ms, the offset is 3 (f3 and f4 time are not aligned, in order to make the measurement time aligned, it can be corrected by offset); The length of time, for example, is 6ms.
下发测量任务3时，测量载频f3上服务小区3的信号质量RSRP，或者合并在测量任务1一起上报，即不下发测量任务3，直接在测量任务1中包含需要上报载频f3上服务小区3的信号质量。 When the measurement task 3 is sent, the signal quality RSRP of the serving cell 3 on the carrier frequency f3 is measured, or the measurement task 1 is reported together, that is, the measurement task 3 is not sent, and the service task 1 needs to be reported on the carrier frequency f3. The signal quality of cell 3.
步骤303：终端收到测量任务，执行f3和f4的RSSI测量。Step 303: The terminal receives the measurement task and performs RSSI measurement of f3 and f4.
对于测量任务1，由于f3上的节点A是终端的服务节点，因此，需要进行两个RSSI的测量和上报，一个是，在节点A被终端占用时，即，执行节点A上的资源竞争过程成功后，终端获得节点A的调度进行数据收发的时间，此时的测量结果为RSSI-1.1。另外一个是，在节点A没有被终端占用时，即，执行节点A上的资源竞争过程没有成功，没有获得节点A的调度进行数据收发的时间，此时的测量结果为RSSI-1.2。For measurement task 1, since node A on f3 is the service node of the terminal, two RSSI measurements and reports need to be performed. One is that when node A is occupied by the terminal, that is, the resource competition process on node A is performed. After the success, the terminal obtains the time for the node A to schedule data transmission and reception. The measurement result at this time is RSSI-1.1. On the other hand, when the node A is not occupied by the terminal, that is, the resource competition process on the node A is not successful, and the time for the data transmission and reception of the node A is not obtained, the measurement result at this time is RSSI-1.2.
对于测量任务2，由于f4上的节点不是终端的服务节点，只需要进行一个RSSI的测量和上报，即指定时间内的RSSI-2。For measurement task 2, since the node on f4 is not the service node of the terminal, only one RSSI measurement and reporting, that is, RSSI-2 within a specified time, is required.
测量f3上小区3的信号质量，上报基站，合并在测量任务1中上报RSRP-1。The signal quality of the cell 3 on the f3 is measured and reported to the base station, and the RSRP-1 is reported in the measurement task 1.
步骤304：基站收到测量任务1、2的测量报告，f3上的整体负荷情况根据RSSI-1.1和RSSI-1.2获知；f4上发整体负荷情况根据RSSI-2获知；终端侧f3的干扰可以通过RSSI-1.1减去RSRP1和RSSI-1.2获知。Step 304: The base station receives the measurement report of the measurement tasks 1, 2, and the overall load situation on f3 is learned according to RSSI-1.1 and RSSI-1.2; the overall load condition of f4 is obtained according to RSSI-2; the interference of terminal side f3 can pass RSSI-1.1 minus RSRP1 and RSSI-1.2 are known.
步骤305：基站发现f3上整体负荷比较高，而f4上整体负荷比较低，给终端下发f4上的邻区测量，从而考虑将小区3换成f4上的小区。Step 305: The base station finds that the overall load on f3 is relatively high, and the overall load on f4 is relatively low, and the neighboring area measurement on f4 is sent to the terminal, so that the cell 3 is replaced by the cell on f4.
基站发现终端侧f3的干扰比较厉害，也可以给终端下发其他载频如f4上的邻区测量，从而考虑将小区3换成f4上的小区。The base station finds that the interference on the terminal side f3 is relatively strong, and can also send the neighboring area measurement on the other carrier frequency, such as f4, to consider changing the cell 3 to the cell on the f4.
实施例二：终端驻留在小区1上，并在小区1上发起RRC连接建立，RRC连接建立过程完成后，UE进入连接态，小区1即为PCell。Embodiment 2: The terminal camps on the cell 1 and initiates an RRC connection establishment on the cell 1. After the RRC connection establishment process is completed, the UE enters a connected state, and the cell 1 is a PCell.
参照图4，图4为本发明实施例二的非授权载波的测量方法的流程示意图，所述方法包括以下步骤：Referring to FIG. 4, FIG. 4 is a schematic flowchart of a method for measuring an unlicensed carrier according to Embodiment 2 of the present invention, where the method includes the following steps:
步骤401：由于业务的需要，基站需要给UE配置载波聚合，基站根据终端的测量报告将小区3(即节点A)配置给终端。Step 401: The base station needs to configure carrier aggregation for the UE, and the base station configures the cell 3 (ie, node A) to the terminal according to the measurement report of the terminal.
这里，小区3称为辅服务小区，小区3为非授权载波上的小区，需要先执行资源竞争过程，成功后才能正常收发数据。由于小区3被配置为终端的服务小区，因此节点A是服务节点。 Here, the cell 3 is referred to as a secondary serving cell, and the cell 3 is a cell on the unlicensed carrier. The resource competition process needs to be performed first, and the data can be normally sent and received after successful. Since the cell 3 is configured as a serving cell of the terminal, the node A is a serving node.
步骤402：基站为了获得整体负荷情况，以及获得终端侧的干扰情况，给终端下发测量任务1，测量载频f3的RSSI；下发测量任务2，测量载频f4的RSSI。Step 402: The base station sends the measurement task 1 to the terminal to measure the RSSI of the carrier frequency f3, and the measurement task 2, and measures the RSSI of the carrier frequency f4, in order to obtain the overall load situation and obtain the interference situation on the terminal side.
下发测量任务1时，给出测量的时间周期和偏移，比如周期是40ms偏移是2；以及测量的时间长度，比如是6ms，或者这个测量时间长度固定不变，由协议规定。When the measurement task 1 is issued, the time period and offset of the measurement are given, for example, the period is 40 ms, the offset is 2; and the measured time length, for example, 6 ms, or the measurement time length is fixed, as specified by the protocol.
由于f3上的节点A是终端的服务节点，因此，通知终端进行两个RSSI的测量和上报，一个是，在节点A被终端占用时，即，执行节点A上的资源竞争过程成功后，终端获得节点A的调度进行数据收发的时间，此时的测量结果为RSSI-1.1；另外一个是，在节点A没有被终端占用时，即，执行节点A上的资源竞争过程没有成功，没有获得节点A的调度进行数据收发的时间，此时的测量结果为RSSI-1.2，另外还包含需要上报载频f3上服务小区3的信号质量。Since the node A on the f3 is the serving node of the terminal, the terminal is notified to perform measurement and reporting of the two RSSIs. One is that when the node A is occupied by the terminal, that is, after the resource competition process on the node A is successful, the terminal Obtain the time for the data transmission and reception of the node A, and the measurement result is RSSI-1.1; the other is, when the node A is not occupied by the terminal, that is, the resource competition process on the node A is not successful, and the node is not obtained. The time for A to schedule data transmission and reception, the measurement result at this time is RSSI-1.2, and the signal quality of the serving cell 3 on the carrier frequency f3 needs to be reported.
下发测量任务2时，也给出测量的时间周期和偏移，比如周期是40ms偏移是3(f3和f4时间不对齐，为了使得测量时间对齐，可以通过偏移来纠正)；以及测量的时间长度，比如是6ms；由于终端没有被配置f4上的节点作为服务节点，通知终端只需要进行一个RSSI的测量和上报，即指定时间内的RSSI-2。When the measurement task 2 is issued, the time period and offset of the measurement are also given. For example, the period is 40ms, the offset is 3 (f3 and f4 time are not aligned, in order to make the measurement time aligned, it can be corrected by offset); The length of time is, for example, 6 ms. Since the terminal is not configured with the node on f4 as the serving node, the terminal is notified that only one RSSI measurement and reporting is required, that is, RSSI-2 within a specified time.
步骤403：终端收到测量任务，执行f3和f4的RSSI测量。Step 403: The terminal receives the measurement task and performs RSSI measurement of f3 and f4.
对于测量任务1，执行相关RSSI的测量，上报RSSI-1.1和RSSI-1.2，测量f3上小区3的信号质量，合并在测量任务1中上报RSRP-1。For measurement task 1, the measurement of the relevant RSSI is performed, the RSSI-1.1 and the RSSI-1.2 are reported, the signal quality of the cell 3 on the f3 is measured, and the RSRP-1 is reported in the measurement task 1.
对于测量任务2，执行相关RSSI的测量，上报RSSI-2。For measurement task 2, perform the relevant RSSI measurement and report RSSI-2.
步骤404：基站收到测量任务1、2的测量报告，f3上的整体负荷情况可以根据RSSI-1.1和RSSI-1.2获知；f4上整体负荷情况可以根据RSSI-2获知；终端侧f3的干扰，可以通过RSSI-1.1减去RSRP1和RSSI-1.2获知。Step 404: The base station receives the measurement report of the measurement tasks 1, 2, and the overall load situation on f3 can be learned according to RSSI-1.1 and RSSI-1.2; the overall load situation on f4 can be learned according to RSSI-2; the interference on the terminal side f3, It can be learned by subtracting RSRP1 and RSSI-1.2 from RSSI-1.1.
步骤405：基站发现f3上整体负荷比较高，而f4上整体负荷比较低，可以给终端下发f4上的邻区测量，从而考虑将小区3换成f4上的小区。Step 405: The base station finds that the overall load on f3 is relatively high, and the overall load on f4 is relatively low, and the neighboring area measurement on f4 can be sent to the terminal, so that the cell 3 is replaced by the cell on f4.
基站发现终端侧f3的干扰比较厉害，也可以给终端下发其他载频如f4 上的邻区测量，从而考虑将小区3换成f4上的小区。The base station finds that the interference on the terminal side f3 is relatively strong, and can also send other carrier frequencies such as f4 to the terminal. The neighboring area is measured, so that the cell 3 is considered to be replaced by the cell on f4.
实施例三：终端驻留在小区1上，并在小区1上发起RRC连接建立，RRC连接建立过程完成后，UE进入连接态，小区1即为PCell。Embodiment 3: The terminal camps on the cell 1 and initiates an RRC connection establishment on the cell 1. After the RRC connection establishment process is completed, the UE enters a connected state, and the cell 1 is a PCell.
参照图5，图5为本发明实施例三的非授权载波的测量方法的流程示意图，所述方法包括以下步骤：Referring to FIG. 5, FIG. 5 is a schematic flowchart of a method for measuring an unlicensed carrier according to Embodiment 3 of the present invention, where the method includes the following steps:
步骤501：由于业务的需要，基站需要给UE配置载波聚合，基站根据终端的测量报告将小区3(即节点A)配置给终端。Step 501: The base station needs to configure carrier aggregation for the UE, and the base station configures the cell 3 (ie, node A) to the terminal according to the measurement report of the terminal.
这里，小区3称为辅服务小区，小区3为非授权载波上的小区，需要先执行资源竞争过程，成功后才能正常收发数据。由于小区3被配置为终端的服务小区，因此节点A是服务节点。Here, the cell 3 is referred to as a secondary serving cell, and the cell 3 is a cell on the unlicensed carrier. The resource competition process needs to be performed first, and the data can be normally sent and received after successful. Since the cell 3 is configured as a serving cell of the terminal, the node A is a serving node.
步骤502：基站为了发现隐藏节点，给终端下发测量任务1，测量载频f3的RSSI。Step 502: The base station sends a measurement task 1 to the terminal to discover the hidden node, and measures the RSSI of the carrier frequency f3.
下发测量任务1时，给出测量的时间周期和偏移，比如周期是40ms偏移是2；以及测量的时间长度，比如是6ms，或者这个测量时间长度固定不变，由协议规定。When the measurement task 1 is issued, the time period and offset of the measurement are given, for example, the period is 40 ms, the offset is 2; and the measured time length, for example, 6 ms, or the measurement time length is fixed, as specified by the protocol.
由于f3上的节点A是终端的服务节点，但是，基站只需要知道隐藏节点的情况，因此，通知终端进行一个RSSI的测量和上报，在节点A被终端占用时，即，执行节点A上的资源竞争过程成功后，终端获得节点A的调度进行数据收发的时间，此时的RSSI-1.1，另外还包含需要上报载频f3上服务小区3的信号质量。Since the node A on the f3 is the serving node of the terminal, the base station only needs to know the situation of the hidden node. Therefore, the terminal is notified to perform an RSSI measurement and reporting. When the node A is occupied by the terminal, that is, the node A is executed. After the resource competition process is successful, the terminal obtains the time for the node A to perform data transmission and reception, and the RSSI-1.1 at this time additionally includes the signal quality of the serving cell 3 that needs to be reported on the carrier frequency f3.
步骤503：终端收到测量任务，执行f3的RSSI测量。Step 503: The terminal receives the measurement task and performs the RSSI measurement of f3.
对于测量任务1，执行相关RSSI的测量，上报RSSI-1.1，测量f3上小区3的信号质量，合并在测量任务1中上报RSRP-1。For measurement task 1, the measurement of the relevant RSSI is performed, the RSSI-1.1 is reported, the signal quality of the cell 3 on the f3 is measured, and the RSRP-1 is reported in the measurement task 1.
步骤504：基站收到测量任务1的测量报告，f3上的隐藏节点情况，可以根据RSSI-1.1减去RSRP1获知。Step 504: The base station receives the measurement report of the measurement task 1, and the hidden node condition on the f3 can be learned by subtracting the RSRP1 from the RSSI-1.1.
步骤505：基站发现f3上存在隐藏节点，而且干扰情况比较厉害，可以给终端下发其他载频如f4上的邻区测量，从而考虑将小区3换成f4上的小区。 Step 505: The base station finds that there is a hidden node on the f3, and the interference situation is relatively strong. The terminal can send the neighboring cell measurement on other carrier frequencies, such as f4, to consider changing the cell 3 to the cell on the f4.
