When the terminal device measures the measurement resource, the power consumption of the terminal device is also increased.
为了降低终端设备的功耗，协议中引入了测量放松的概念。目前，协议准备引入无线链路监测(radio link monitoring，RLM)放松和波束失败检测(beam failure detection，BFD)放松。但是，在双连接(dual connectivity，DC)架构下，应当如何执行RLM放松或BFD放松，是亟待解决的问题。In order to reduce the power consumption of terminal equipment, the concept of measurement relaxation is introduced in the protocol. Currently, the protocol is preparing to introduce radio link monitoring (RLM) relaxation and beam failure detection (BFD) relaxation. However, under the dual connectivity (DC) architecture, how to perform RLM relaxation or BFD relaxation is an urgent problem to be solved.

随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性和复杂性，第三代移动通信合作伙伴计划(3rd generation partnership project，3GPP)国际标准组织开始研发5G。5G的主要应用场景可以包括：增强移动超宽带(enhance mobile broadband，eMBB)、低时延高可靠通信(ultra reliable low latency communications，URLLC)和大规模机器类通信(massive machine type communication，mMTC)。本申请实施例的方案可适用于上述任意一种场景。With people's pursuit of speed, delay, high-speed mobility, energy efficiency and the diversity and complexity of business in future life, the 3rd Generation Partnership Project (3GPP) international standards organization began to develop 5G. The main application scenarios of 5G can include: enhanced mobile broadband (eMBB), low latency and highly reliable communications (ultra reliable low latency communications, URLLC) and massive machine type communications (massive machine type communication, mMTC). The solutions in the embodiments of the present application may be applicable to any of the above scenarios.
eMBB业务的主要特点是传输的数据量大，传输速率高。在传输eMBB业务的数据时，一般采用较长时间的时间调度单元来进行数据的传输以提高数据传输效率。典型的eMBB业务可以包括：超高清视频、增强现实(augmented reality，AR)、虚拟现实(virtual reality，VR)等。The main characteristics of the eMBB service are the large amount of transmitted data and the high transmission rate. When transmitting the data of the eMBB service, a relatively long time scheduling unit is generally used for data transmission to improve data transmission efficiency. Typical eMBB services may include: ultra-high-definition video, augmented reality (augmented reality, AR), virtual reality (virtual reality, VR), etc.
URLLC业务的主要特点是要求超高的可靠性和超低的延时，传输的数据量较少并且具有突发性。例如，在不考虑可靠性的情况下，URLLC业务的传输时延要求一般在0.5毫秒以内。在可靠性要求达到99.999％的前提下，URLLC业务的传输时延要求在1ms以内。由于URLLC业务具有突发性和随机性，因此，URLLC业务可能在很长一段时间内都不会产生数据包，也可能在很短时间内产生多个数据包，这些数据包在多数情况下为小包(例如，大小为50个字节的数据包)。典型的URLLC业务可以包括：工业制造或生产流程中的无线控制，无人驾驶汽车或无人驾驶飞机的运动控制以及远程修理，远程手术等触觉交互类应用。The main feature of the URLLC service is that it requires ultra-high reliability and ultra-low delay, and the amount of transmitted data is small and bursty. For example, without considering the reliability, the transmission delay requirement of the URLLC service is generally within 0.5 milliseconds. On the premise that the reliability requirement reaches 99.999%, the transmission delay of the URLLC service is required to be within 1ms. Due to the suddenness and randomness of the URLLC service, the URLLC service may not generate data packets for a long period of time, or may generate multiple data packets in a short period of time. In most cases, these data packets are Small packets (for example, packets of size 50 bytes). Typical URLLC services can include: wireless control in industrial manufacturing or production processes, motion control of driverless cars or drones, and tactile interaction applications such as remote repairs and remote surgery.

无线资源控制(radio resource control，RRC)状态Radio resource control (RRC) status
目前，协议中定义了终端设备的三种RRC状态：RRC连接(RRC_connected)态、RRC空闲(RRC-Idle)态和RRC非激活(RRC-Inactive)态。Currently, the protocol defines three RRC states of the terminal equipment: RRC connected (RRC_connected) state, RRC idle (RRC-Idle) state and RRC inactive (RRC-Inactive) state.
RRC_connected态可以指终端设备完成随机接入过程之后，未进行RRC释放时所处的状态。终端设备和网络设备(例如接入网络设备)之间存在RRC连接。在RRC_connected态下，终端设备可以和网络设备进行数据传输，如进行下行数据传输和/或上行数据传输。或者，终端设备也可以和网络设备进行终端设备特定的数据信道和/或控制信道的传输，以传输该终端设备的特定信息或单播信息。The RRC_connected state may refer to the state in which the terminal equipment is in when the RRC release is not performed after completing the random access process. An RRC connection exists between a terminal device and a network device (for example, an access network device). In the RRC_connected state, the terminal device can perform data transmission with the network device, such as performing downlink data transmission and/or uplink data transmission. Alternatively, the terminal device may also perform terminal device-specific data channel and/or control channel transmission with the network device, so as to transmit specific information or unicast information of the terminal device.
在RRC_connected态下，网络设备可以确定终端设备小区级别的位置信息，也就是说，网络设备 可以确定终端设备所属的小区。在RRC_connected态下，终端设备发生位置移动后，如从一个小区移动到另一个小区后，网络设备可以控制终端设备进行小区切换。由此可见，终端设备在RRC_connected态下的移动性是网络设备控制的移动性，终端设备可以按照网络下发的指令切换到指定的小区。In the RRC_connected state, the network device can determine the cell-level location information of the terminal device, that is, the network device can determine the cell to which the terminal device belongs. In the RRC_connected state, after the terminal device moves, for example, after moving from one cell to another cell, the network device can control the terminal device to perform cell handover. It can be seen from this that the mobility of the terminal device in the RRC_connected state is mobility controlled by the network device, and the terminal device can switch to a designated cell according to an instruction issued by the network.
RRC-Idle态是指终端设备在小区中驻留，但是未进行随机接入时终端设备所处的状态。终端设备通常在开机之后，或者在RRC释放之后进入RRC-Idle态。在RRC-Idle态下，终端设备和网络设备(例如驻留网络设备)之间没有RRC连接，网络设备没有存储终端设备的上下文，网络设备与核心网之间没有建立针对该终端设备的连接。如果终端设备需要从RRC-Idle态进入RRC_connected态，则需要发起RRC连接建立过程。The RRC-Idle state refers to the state that the terminal equipment is in when it camps in a cell but does not perform random access. The terminal device usually enters the RRC-Idle state after being powered on or after the RRC is released. In the RRC-Idle state, there is no RRC connection between the terminal device and the network device (for example, a resident network device), the network device does not store the context of the terminal device, and no connection for the terminal device is established between the network device and the core network. If the terminal device needs to enter the RRC_connected state from the RRC-Idle state, it needs to initiate the RRC connection establishment process.
在RRC-Idle态下，核心网(core network，CN)可以向终端设备发送寻呼消息，也就是说，寻呼过程可以由CN触发。可选地，寻呼区域也可以由CN配置。在RRC-Idle态下，终端设备发生位置移动后，如从一个小区移动到另一个小区后，终端设备可以发起小区重选。由此可见，终端设备在RRC-Idle态的移动性为基于终端设备的小区重选。In the RRC-Idle state, the core network (core network, CN) can send a paging message to the terminal device, that is, the paging process can be triggered by the CN. Optionally, the paging area can also be configured by the CN. In the RRC-Idle state, after the terminal equipment moves, for example, after moving from one cell to another, the terminal equipment can initiate cell reselection. It can be seen that the mobility of the terminal equipment in the RRC-Idle state is based on the cell reselection of the terminal equipment.
RRC-Inactive态是为了降低空口信令、快速恢复无线连接和快速恢复数据业务，新定义的状态。RRC_Inactive态是处于连接态和空闲态之间的一个状态。终端设备之前已经进入了RRC_connected态，然后释放了与网络设备的RRC连接，但是网络设备保存了该终端设备的上下文。另外，网络设备与核心网建立的针对该终端设备的连接没有被释放，也就是说，RAN与CN之间的用户面承载和控制面承载仍被维护，即存在CN-NR的连接。The RRC-Inactive state is a newly defined state to reduce air interface signaling, quickly restore wireless connections, and quickly restore data services. The RRC_Inactive state is a state between the connected state and the idle state. The terminal device has entered the RRC_connected state before, and then releases the RRC connection with the network device, but the network device saves the context of the terminal device. In addition, the connection between the network device and the core network for the terminal device is not released, that is, the user plane bearer and control plane bearer between the RAN and the CN are still maintained, that is, there is a CN-NR connection.
在RRC-Inactive态下，RAN可以向终端设备发送寻呼消息，也就是说，寻呼过程可以由RAN触发。基于RAN的寻呼区域由RAN管理，网络设备能够知道终端设备的位置是基于RAN的寻呼区域级别的。In the RRC-Inactive state, the RAN can send a paging message to the terminal device, that is, the paging process can be triggered by the RAN. The RAN-based paging area is managed by the RAN, and the network device can know the location of the terminal device based on the paging area level of the RAN.
在RRC-Inactive态下，终端设备发生位置移动后，如从一个小区移动到另一个小区，终端设备可以发起小区重选。由此可见，终端设备在RRC-Inactive态下的移动性为基于终端设备的小区重选。In the RRC-Inactive state, after the terminal equipment moves, such as moving from one cell to another, the terminal equipment can initiate cell reselection. It can be seen that the mobility of the terminal equipment in the RRC-Inactive state is based on the cell reselection of the terminal equipment.
无线资源管理(radio resource management，RRM)测量放松Radio resource management (RRM) measurement relaxation
由上文的描述可知，由于终端设备的移动性，终端设备可能从一个小区的覆盖范围移动到另一个小区的覆盖范围。为了保证终端设备的业务连续性和通信质量，终端设备可以进行RRM测量，从而实现小区重选(reselection)或者小区切换(handover)。It can be seen from the above description that due to the mobility of the terminal equipment, the terminal equipment may move from the coverage area of one cell to the coverage area of another cell. In order to ensure the service continuity and communication quality of the terminal equipment, the terminal equipment can perform RRM measurement, so as to implement cell reselection (reselection) or cell handover (handover).
对于处于RRC-Inactive态和RRC-Idle态的终端设备，终端设备可以进行RRM测量，并基于RRM测量结果进行小区重选。对于处于RRC_connected态的终端设备，终端设备可以进行RRM测量，并将测量结果上报给网络设备。网络设备可以基于信号测量结果控制终端设备进行小区切换。For a terminal device in the RRC-Inactive state and RRC-Idle state, the terminal device can perform RRM measurement and perform cell reselection based on the RRM measurement result. For a terminal device in the RRC_connected state, the terminal device can perform RRM measurement and report the measurement result to the network device. The network device can control the terminal device to perform cell handover based on the signal measurement result.
在进行RRM测量时，终端设备可以对多个小区(如服务小区以及至少一个邻小区)进行RRM测量，得到多个小区的信号测量结果。该多个小区的信号测量结果可用于进行小区重选或小区切换。例如，在进行小区重选时，终端设备可以选择信号质量好的小区进行接入。又例如，在进行小区切换时，终端设备可以从服务小区切换到信号质量更好的目标小区。When performing RRM measurement, the terminal device may perform RRM measurement on multiple cells (such as a serving cell and at least one neighboring cell) to obtain signal measurement results of multiple cells. The signal measurement results of the multiple cells can be used for cell reselection or cell handover. For example, when performing cell reselection, the terminal device may select a cell with good signal quality for access. For another example, when cell switching is performed, the terminal device may switch from a serving cell to a target cell with better signal quality.
RRM测量可以是基于同步/物理广播信道块(synchronization/physicalbroadcast channel block，SSB)和/或信道状态信息参考信号(channel stateinformation-reference signal，CSI-RS)的RRM测量。网络设备可以为终端设备配置多个小区的SSB和/或CSI-RS资源，终端设备可以对该多个小区进行测量，以得到多个小区的信号测量结果。The RRM measurement may be RRM measurement based on a synchronization/physical broadcast channel block (SSB) and/or a channel state information-reference signal (CSI-RS). The network device may configure SSB and/or CSI-RS resources of multiple cells for the terminal device, and the terminal device may measure the multiple cells to obtain signal measurement results of the multiple cells.
信号测量结果可以包括参考信号接收功率(reference signal receiving power，RSRP)的测量结果、参考信号接收质量(reference signal receiving quality，RSRQ)的测量结果和信号干扰噪声比(signal-to jamming and noise ratio，SINR)的测量结果中的至少一种。可以理解的是，一个小区的信号测量结果可用于表征该小区的信号质量。The signal measurement results may include reference signal receiving power (reference signal receiving power, RSRP) measurement results, reference signal receiving quality (reference signal receiving quality, RSRQ) measurement results and signal-to jamming and noise ratio (signal-to jamming and noise ratio, SINR) at least one of the measurement results. It can be understood that the signal measurement result of a cell can be used to characterize the signal quality of the cell.
为了保证终端设备的业务连续性和通信质量，终端设备需要不断地进行RRM测量，例如，终端设备周期性地对多个小区进行RRM测量。相应地，终端设备就会存在一定的功耗。但是，在某些场景下，如终端设备基本不移动，或者终端设备处于小区的中心位置，终端设备对小区切换或小区重选的需求不大，如果终端设备还是持续地进行RRM测量，无疑是对终端设备电量的浪费。In order to ensure the service continuity and communication quality of the terminal equipment, the terminal equipment needs to continuously perform RRM measurement, for example, the terminal equipment periodically performs RRM measurement on multiple cells. Correspondingly, the terminal device will have a certain power consumption. However, in some scenarios, if the terminal device basically does not move, or the terminal device is located in the center of the cell, the terminal device has little demand for cell handover or cell reselection. If the terminal device continues to perform RRM measurement, it is undoubtedly Waste of power for terminal equipment.
基于上述考虑，为了降低终端设备的功耗，通信***中引入了节能技术，提出RRM测量放松(RRM measurement relax)的概念。RRM测量放松也可以称为邻区测量放松，或邻区RRM测量放松。RRM测量放松的实现方式有多种，本申请实施例对此不做具体限定。例如，终端设备可以通过增大RRM测量的周期(即减少RRM测量的次数)来实现RRM测量放松。又例如，终端设备可以通过减小测量的邻小区的数量来实现RRM测量放松。再例如，终端设备可以通过减小测量的频点数来实现RRM测量放松。Based on the above considerations, in order to reduce the power consumption of terminal equipment, energy-saving technology is introduced into the communication system, and the concept of RRM measurement relax (RRM measurement relax) is proposed. RRM measurement relaxation may also be referred to as neighborhood measurement relaxation, or neighborhood RRM measurement relaxation. There are multiple implementation manners of RRM measurement relaxation, which are not specifically limited in this embodiment of the present application. For example, the terminal device can implement RRM measurement relaxation by increasing the period of RRM measurement (that is, reducing the number of times of RRM measurement). For another example, the terminal device may implement RRM measurement relaxation by reducing the number of neighboring cells to be measured. For another example, the terminal device may implement RRM measurement relaxation by reducing the number of frequency points to be measured.
针对终端设备在RRC-Idle态和RRC-Inactive态的RRM测量放松，协议中定义了两个准则，分别 是非小区边缘(not-cell-edge)准则和低移动性(low-mobility)准则。终端设备可以根据信号测量结果，确定其是否满足not-cell-edge准则和/或low-mobility准则。在终端设备满足not-cell-edge准则和/或low-mobility准则的情况下，终端设备可以进行RRM测量放松。For the RRM measurement relaxation of terminal equipment in RRC-Idle state and RRC-Inactive state, two criteria are defined in the protocol, namely the not-cell-edge criterion and the low-mobility criterion. The terminal device can determine whether it satisfies the not-cell-edge criterion and/or the low-mobility criterion according to the signal measurement result. When the terminal device satisfies the not-cell-edge criterion and/or the low-mobility criterion, the terminal device can perform RRM measurement relaxation.
not-cell-edge准则主要用于确定终端设备是否处于服务小区的边缘小区位置。如果终端设备处于服务小区的非边缘小区位置，则终端设备对小区重选的需求不大，可以进行RRM测量放松，达到终端设备节能的目的。如果终端设备处于服务小区的边缘小区位置，则终端设备对小区重选的需求较大，终端设备可以不进行RRM测量放松。The not-cell-edge criterion is mainly used to determine whether the terminal equipment is located in the edge cell of the serving cell. If the terminal device is in a non-edge cell of the serving cell, the terminal device has little need for cell reselection, and RRM measurement can be relaxed to achieve the purpose of energy saving of the terminal device. If the terminal device is located in an edge cell of the serving cell, the terminal device has a greater demand for cell reselection, and the terminal device may relax without performing RRM measurement.
not-cell-edge准则主要定义了信号测量结果的门限值。通过将信号测量结果与该门限值进行比较，可以确定终端设备是否处于非边缘小区位置。例如，如果信号测量结果大于门限值，则表示终端设备处于服务小区的非边缘小区位置；如果信号测量结果小于或等于门限值，则表示终端设备处于服务小区的边缘小区位置。The not-cell-edge criterion mainly defines the threshold value of the signal measurement result. By comparing the signal measurement result with the threshold value, it can be determined whether the terminal device is located in a non-edge cell. For example, if the signal measurement result is greater than the threshold value, it indicates that the terminal device is located in a non-edge cell of the serving cell; if the signal measurement result is less than or equal to the threshold value, it indicates that the terminal device is located in an edge cell of the serving cell.
下面以信号测量结果为RSRP和RSRQ的信号测量结果为例，对not-cell-edge准则进行介绍。网络设备可以通过向终端设备配置小区边缘评估(cellEdgeEvaluation)参数，来定义not-cell-edge准则的两个门限值s-SearchThresholdP和s-SearchThresholdQ。其中，s-SearchThresholdP为RSRP的测量门限值，s-SearchThresholdQ为RSRQ的测量门限值。终端设备可以对服务小区的RSRP和RSRQ进行测量，得到服务小区的RSRP的测量值和RSRQ的测量值。当服务小区的RSRP的测量值大于s-SearchThresholdP，且RSRQ的测量值大于s-SearchThresholdQ时，则终端设备满足not-cell-edge准则，终端设备可以进行RRM测量放松。The not-cell-edge criterion is introduced below by taking the signal measurement results of RSRP and RSRQ as an example. The network device can define two thresholds s-SearchThresholdP and s-SearchThresholdQ of the not-cell-edge criterion by configuring a cell edge evaluation (cellEdgeEvaluation) parameter to the terminal device. Wherein, s-SearchThresholdP is the measurement threshold value of RSRP, and s-SearchThresholdQ is the measurement threshold value of RSRQ. The terminal device can measure the RSRP and RSRQ of the serving cell, and obtain the measured value of RSRP and the measured value of RSRQ of the serving cell. When the measured value of RSRP of the serving cell is greater than s-SearchThresholdP, and the measured value of RSRQ is greater than s-SearchThresholdQ, the terminal device meets the not-cell-edge criterion, and the terminal device can perform RRM measurement relaxation.
当然，网络设备也可以仅配置s-SearchThresholdP和s-SearchThresholdQ中的一个参数。例如，网络设备可以仅配置s-SearchThresholdP，而不配置s-SearchThresholdQ，在该情况下，终端设备可以仅对服务小区的RSRP进行测量。当服务小区的RSRP的测量值大于s-SearchThresholdP时，则终端设备满足not-cell-edge准则，终端设备可以进行RRM测量放松。又例如，网络设备可以仅配置s-SearchThresholdQ，而不配置s-SearchThresholdP，在该情况下，终端设备可以仅对服务小区的RSRQ进行测量。当服务小区的RSRQ的测量值大于s-SearchThresholdQ时，则终端设备满足not-cell-edge准则，终端设备可以进行RRM测量放松。Certainly, the network device may also configure only one parameter among s-SearchThresholdP and s-SearchThresholdQ. For example, the network device may only configure s-SearchThresholdP but not s-SearchThresholdQ. In this case, the terminal device may only measure the RSRP of the serving cell. When the RSRP measurement value of the serving cell is greater than s-SearchThresholdP, the terminal device meets the not-cell-edge criterion, and the terminal device can perform RRM measurement relaxation. For another example, the network device may only configure s-SearchThresholdQ but not s-SearchThresholdP. In this case, the terminal device may only measure the RSRQ of the serving cell. When the measured value of RSRQ of the serving cell is greater than s-SearchThresholdQ, the terminal device satisfies the not-cell-edge criterion, and the terminal device can perform RRM measurement relaxation.
low-mobility准则主要用于确定终端设备是否处于低移动状态。如果终端设备处于低移动状态，即终端设备所处的位置相对固定，则终端设备对小区重选的需求不大，终端设备可以进行RRM测量放松。如果终端设备处于高移动状态，即终端设备的位置变化很大，则终端设备对小区重选的需求较大，终端设备可以不进行RRM测量放松。The low-mobility criterion is mainly used to determine whether the terminal device is in a low mobility state. If the terminal device is in a low mobility state, that is, the location of the terminal device is relatively fixed, the terminal device has little demand for cell reselection, and the terminal device can perform RRM measurement relaxation. If the terminal device is in a highly mobile state, that is, the location of the terminal device changes greatly, the terminal device has a greater demand for cell reselection, and the terminal device may not perform RRM measurement to relax.
终端设备是否处于低移动状态可以基于服务小区的信号质量进行判断。例如，终端设备可以在不同的时间对服务小区的信号质量进行测量。如果服务小区的信号质量在不同的时间变化很少，即服务小区的信号质量比较稳定，则表示终端设备处于低移动状态。Whether the terminal device is in the low mobility state can be judged based on the signal quality of the serving cell. For example, the terminal device may measure the signal quality of the serving cell at different times. If the signal quality of the serving cell changes little at different times, that is, the signal quality of the serving cell is relatively stable, it means that the terminal device is in a low mobility state.
服务小区的信号质量可以用以下信息中的至少一种来表示：RSRP、RSRQ、SINR。以RSRP为例，终端设备可以对服务小区的RSRP进行测量。如果服务小区的RSRP变化很少，则表示终端设备处于低移动状态，终端设备可以进行RRM测量放松。The signal quality of the serving cell can be represented by at least one of the following information: RSRP, RSRQ, SINR. Taking RSRP as an example, the terminal device can measure the RSRP of the serving cell. If the RSRP of the serving cell changes little, it means that the terminal device is in a low mobility state, and the terminal device can perform RRM measurement relaxation.
针对low-mobility准则，终端设备可以通过判断是否满足低移动性准则参数，来确定是否满足low-mobility准则。目前，协议中定义了两个低移动性准则参数t-SearchDeltaP和s-SearchDeltaP。如果服务小区的信号质量在t-SearchDeltaP时间内小于门限值s-SearchDeltaP，则表示终端设备满足low-mobility准则，终端设备可以进行RRM测量放松。For the low-mobility criterion, the terminal device may determine whether the low-mobility criterion is satisfied by judging whether the low-mobility criterion parameter is satisfied. Currently, two low mobility criterion parameters t-SearchDeltaP and s-SearchDeltaP are defined in the protocol. If the signal quality of the serving cell is less than the threshold s-SearchDeltaP within the t-SearchDeltaP time, it means that the terminal device meets the low-mobility criterion, and the terminal device can perform RRM measurement relaxation.
如果终端设备同时被配置了not-cell-edge准则和low-mobility准则，网络设备还可以通知终端设备RRM测量放松的触发条件，终端设备可以在满足触发条件的情况下进行RRM测量放松。该触发条件可以为满足not-cell-edge准则和/或low-mobility准则。例如，网络设备可以向终端设备指示not-cell-edge准则和low-mobility准则的关系，如网络设备可以指示二者是“和”的关系，还是“或”的关系。如果二者是“和”的关系，则表示终端设备需要在同时满足not-cell-edge准则和low-mobility准则的情况下，才能进行RRM测量放松。如果二者是“或”的关系，则表示终端设备只要满足其中任意一个准则(如not-cell-edge准则或low-mobility准则)，就可以进行RRM测量放松。If the terminal device is configured with the not-cell-edge rule and the low-mobility rule at the same time, the network device can also notify the terminal device of the trigger condition of RRM measurement relaxation, and the terminal device can perform RRM measurement relaxation when the trigger condition is met. The trigger condition may be meeting the not-cell-edge criterion and/or the low-mobility criterion. For example, the network device may indicate to the terminal device the relationship between the not-cell-edge criterion and the low-mobility criterion, for example, the network device may indicate whether the two are in an "and" relationship or an "or" relationship. If the relationship between the two is "and", it means that the terminal device needs to meet the not-cell-edge criterion and the low-mobility criterion at the same time before performing RRM measurement relaxation. If the relationship between the two is "or", it means that the terminal device can perform RRM measurement relaxation as long as it satisfies any one of the criteria (such as the not-cell-edge criterion or the low-mobility criterion).
在其他的测量场景中，如RLM和BFD，终端设备也存在一定的功耗。为了进一步降低终端设备的功耗，达到节能的目的，还可以对这些测量场景进行测量放松。下面分别对RLM和BFD进行描述。In other measurement scenarios, such as RLM and BFD, terminal equipment also consumes a certain amount of power consumption. In order to further reduce the power consumption of the terminal equipment and achieve the purpose of saving energy, it is also possible to perform measurement relaxation on these measurement scenarios. RLM and BFD are described respectively below.

RLM可以指终端设备在RRC_connected态下，对服务小区的下行链路的信道质量进行监测。终端设备可以在与网络设备建立RRC连接后，进行RLM测量以维持链路状态，保证数据成功传输。在移动通信***中，由于终端设备的移动、环境的变化等原因，可能会导致终端设备与网络设备之间的无线链路(radio link)的质量时好时坏。为了保证通信的稳定性，终端设备需要对无线链路的质量进行持 续监测，该过程可以称为无线链路监测。RLM may mean that the terminal equipment monitors the downlink channel quality of the serving cell in the RRC_connected state. After the terminal device establishes an RRC connection with the network device, it can perform RLM measurement to maintain the link state and ensure successful data transmission. In a mobile communication system, the quality of a radio link (radio link) between a terminal device and a network device may be intermittent due to reasons such as movement of the terminal device and changes in the environment. In order to ensure the stability of communication, the terminal equipment needs to continuously monitor the quality of the wireless link, and this process can be called wireless link monitoring.
RLM的目的是在当前服务小区(serving cell)质量不合适时更换小区。基本机制是网络给终端设备配置用于RLM的参考信号(即监测资源)，终端设备持续地监测这些RLM资源并根据一定规则判断无线链路是否出现问题。其中，用于RLM的参考信号(reference signal，RS)可以为SSB和/或CSI-RS等。The purpose of RLM is to replace the cell when the quality of the current serving cell is not suitable. The basic mechanism is that the network configures reference signals for RLM (monitoring resources) to the terminal equipment, and the terminal equipment continuously monitors these RLM resources and judges whether there is a problem with the wireless link according to certain rules. Wherein, the reference signal (reference signal, RS) used for RLM may be SSB and/or CSI-RS, etc.
关于RLM测量，终端设备内部的物理(physical，PHY)层可以检测信号质量，终端设备内部的高层(如介质访问控制(medium access control，MAC)层)可以根据信号的质量，确定无线链路的状态。具体行为可以如下：With regard to RLM measurement, the physical (PHY) layer inside the terminal device can detect the signal quality, and the high-layer (such as the medium access control (MAC) layer) inside the terminal device can determine the quality of the wireless link according to the quality of the signal. state. The specific behavior can be as follows:
1、物理层可以检测RLM-RS以确定下行无线链路质量。终端设备可以根据RLM-RS的RSRP、RSRQ、SINR中的至少一种，对下行链路质量进行估计，如估计下行链路的误块率(block error ratio，BLER)。若所有用于RLM-RS测量的下行无线链路质量结果都低于门限值Qout，则物理层可以向高层发送失步指示(out-of-sync indication)信息。若至少一个RLM-RS测量的下行无线链路质量结果高于门限值Qin，则物理层可以向高层发送同步指示(in-sync indication)信息。1. The physical layer can detect the RLM-RS to determine the quality of the downlink radio link. The terminal device can estimate the downlink quality according to at least one of RSRP, RSRQ, and SINR of the RLM-RS, such as estimating a block error ratio (block error ratio, BLER) of the downlink. If all downlink radio link quality results used for RLM-RS measurement are lower than the threshold value Qout, the physical layer may send out-of-sync indication (out-of-sync indication) information to the upper layer. If the downlink radio link quality result measured by at least one RLM-RS is higher than the threshold value Qin, the physical layer may send in-sync indication (in-sync indication) information to the upper layer.
Qin和Qout表示物理下行控制信道(physical downlinkcontrol channel，PDCCH)的BLER的门限值。终端设备可以对PDCCH的BLER(如PDCCH format 1-0的BLER)进行检测，并与Qin和Qout进行比较，以确定终端设备是处于同步状态还是失步状态。Qin and Qout represent the threshold value of the BLER of the physical downlink control channel (physical downlink control channel, PDCCH). The terminal device can detect the BLER of the PDCCH (such as the BLER of PDCCH format 1-0), and compare it with Qin and Qout to determine whether the terminal device is in a synchronous state or an out-of-synchronization state.
Qin和Qout可以是针对每个小区(per cell)单独配置的，也可以是多个小区共用一组Qin和Qout。终端设备可以根据当前所处的服务小区，确定与该服务小区对应的Qin和Qout，以进行无线链路监测。Qin and Qout can be configured individually for each cell (per cell), or a group of Qin and Qout can be shared by multiple cells. The terminal device can determine the Qin and Qout corresponding to the serving cell according to the serving cell currently located, so as to monitor the radio link.
Qin和Qout的值可以是网络设备配置的，或-者也可以是协议中默认的值。例如，网络设备可以通过RRC信令为终端设备配置Qin和Qout，终端设备可以通过接收RRC信令来确定Qin和Qout。又例如，Qin和Qout也可以是协议中默认的值，如Qout的默认值可以为10％，Qin的默认值可以为2％。可选地，如果网络设备为终端设备配置了Qin和Qout，则终端设备可以使用配置的Qin和Qout进行同步或失步判断；如果网络设备没有为终端设备配置Qin和Qout，则终端设备可以使用协议中默认的Qin和Qout进行同步或失步判断。The values of Qin and Qout may be configured by the network device, or may be default values in the protocol. For example, the network device can configure Qin and Qout for the terminal device through RRC signaling, and the terminal device can determine Qin and Qout by receiving the RRC signaling. For another example, Qin and Qout may also be default values in the protocol, for example, the default value of Qout may be 10%, and the default value of Qin may be 2%. Optionally, if the network device configures Qin and Qout for the terminal device, the terminal device can use the configured Qin and Qout for synchronization or out-of-sync judgment; if the network device does not configure Qin and Qout for the terminal device, the terminal device can use The default Qin and Qout in the protocol are used for synchronous or out-of-synchronization judgment.
2、高层确定无线链路的状态。当高层接收到物理层连续指示的N310个out-of-sync indication，且终端设备的定时器T310、T301、T304、T311都不在运行中，则启动定时器T310，此时可以认为终端设备检测到物理层问题。在定时器T310运行过程中，即定时器T310超时前，当高层接收到物理层连续指示的N311个in-sync indication，则停止定时器T310，此时可以认为终端设备从物理层问题中恢复，如恢复下行同步。当定时器T310超时，高层没有连续收到来自物理层的N311个in-sync indication，此时可以认为终端设备处于下行失步状态，即终端设备发生了无线链路失败(radio link failure，RLF)。2. The upper layer determines the status of the wireless link. When the upper layer receives N310 out-of-sync indications continuously indicated by the physical layer, and the timers T310, T301, T304, and T311 of the terminal device are not running, the timer T310 is started, and it can be considered that the terminal device has detected Physical layer issues. During the running of the timer T310, that is, before the timer T310 expires, when the upper layer receives N311 in-sync indications continuously indicated by the physical layer, the timer T310 is stopped, and the terminal device can be considered to have recovered from the physical layer problem at this time. Such as restoring downlink synchronization. When the timer T310 expires and the upper layer does not receive N311 in-sync indications from the physical layer continuously, it can be considered that the terminal device is in a downlink out-of-sync state, that is, the terminal device has a radio link failure (RLF) .
上述定时器参数T310、T301、T304、T311和/或常量参数N310、N311可以是网络设备通过专用信令配置给终端设备的，或者也可以是通过***广播配置给终端设备的。例如，网络设备可以通过专用信令给终端设备配置参数RLF定时器与常量(RLF-TimersAndConstants IE)，该参数RLF-TimersAndConstants IE包括上述定时器参数和常量参数。又例如，网络设备可以通过***广播(如SIB1)为终端设备配置参数UE定时器与常量(ue-TimersAndConstants IE)，该ue-TimersAndConstants IE包括上述定时器参数和常量参数。可选地，如果网络设备通过专用信令为终端设备配置了RLF-TimersAndConstants IE，则终端设备可以优先使用RLF-TimersAndConstants IE中的参数；如果网络设备没有通过专用信令为终端设备配置RLF-TimersAndConstants IE，则终端设备可以使用ue-TimersAndConstants IE中的参数。The above timer parameters T310, T301, T304, T311 and/or constant parameters N310, N311 may be configured to the terminal device by the network device through dedicated signaling, or may be configured to the terminal device through system broadcast. For example, the network device can configure the parameter RLF timers and constants (RLF-TimersAndConstants IE) to the terminal device through dedicated signaling, and the parameter RLF-TimersAndConstants IE includes the above timer parameters and constant parameters. For another example, the network device can configure parameters UE timers and constants (ue-TimersAndConstants IE) for the terminal device through system broadcast (such as SIB1), and the ue-TimersAndConstants IE includes the above-mentioned timer parameters and constant parameters. Optionally, if the network device configures RLF-TimersAndConstants IE for the terminal device through dedicated signaling, the terminal device can preferentially use the parameters in the RLF-TimersAndConstants IE; if the network device does not configure RLF-TimersAndConstants for the terminal device through dedicated signaling IE, the terminal device can use the parameters in ue-TimersAndConstants IE.
BFDBFD
BFD可以指终端设备在RRC_connected态下对波束的质量进行监测。BFD的目的是在当前波束质量不合适时进行波束恢复，更换波束。其基本机制可以是网络设备给终端设备配置用于BFD的参考信号(即监测资源)，终端设备持续地监测这些用于BFD的监测资源，并根据一定规则判断波束是否出现问题。BFD may mean that the terminal equipment monitors the quality of the beam in the RRC_connected state. The purpose of BFD is to restore the beam and replace the beam when the current beam quality is not suitable. The basic mechanism can be that the network device configures reference signals (ie, monitoring resources) for BFD to the terminal device, and the terminal device continuously monitors these monitoring resources for BFD, and judges whether there is a problem with the beam according to certain rules.
用于BFD的监测资源可以是SSB资源和/或CSI-RS资源。终端设备可以基于网络设备配置的参数执行波束失败检测和波束失败恢复过程。波束失败检测可以指终端设备在当前服务小区的SSB和/或CSI-RS上检测到波束失败。波束失败恢复用于终端设备向服务小区指示一个新的SSB/CSI-RS。具体行为可以如下：The monitoring resources used for BFD may be SSB resources and/or CSI-RS resources. The terminal device can perform beam failure detection and beam failure recovery processes based on parameters configured by the network device. The beam failure detection may refer to that the terminal device detects a beam failure on the SSB and/or CSI-RS of the current serving cell. Beam failure recovery is used for terminal equipment to indicate a new SSB/CSI-RS to the serving cell. The specific behavior can be as follows:
物理层操作：网络设备通过RRC信令给终端设备配置用于波束失败检测的SSB资源和/或CSI-RS资源，同时配置参数BFI最大值(beamFailureInstanceMaxCount)和BFD定时器(beamFailureDetectionTimer)。物理层根据规定的评估周期持续地对BFD监测资源进行测量评估。当所有BFD资源的质量均低于给定阈值Qout时，物理层向MAC层发送一个波束失败实例(beam failure instance，BFI)指示。Physical layer operation: The network device configures the terminal device with SSB resources and/or CSI-RS resources for beam failure detection through RRC signaling, and configures the maximum value of BFI (beamFailureInstanceMaxCount) and BFD timer (beamFailureDetectionTimer). The physical layer continuously measures and evaluates BFD monitoring resources according to the specified evaluation cycle. When the quality of all BFD resources is lower than the given threshold Qout, the physical layer sends a beam failure instance (BFI) indication to the MAC layer.
高层操作：高层在接收到BFI指示时认为波束出现问题，启动或重启BFD定时器(beamFailureDetectionTimer)，将BFI计数器(BFI_COUNTER)累加1，并累计已收到的BFI个数。如果BFI_COUNTER大于或等于参数BFI最大值(beamFailureInstanceMaxCount)，则触发波束失败恢复(beam failure recovery，BFR)过程。终端设备可以发起随机接入过程，以进行波束失败恢复。例如，终端设备可以在主小区(primary cell，PCell)或主辅小区(primary secondary cell，SpCell)发起随机接入过程。如果beamFailureDetectionTimer超时，或者终端设备接收到用于波束失败检测的参数SSB/CSI-RS资源、beamFailureInstanceMaxCount和beamFailureDetectionTimer中的至少一个参数的重配置，则将BFI_COUNTER重置为零。High-level operation: When the high-level receives the BFI indication, it considers that there is a problem with the beam, starts or restarts the BFD timer (beamFailureDetectionTimer), adds 1 to the BFI counter (BFI_COUNTER), and accumulates the number of received BFIs. If BFI_COUNTER is greater than or equal to the parameter BFI maximum value (beamFailureInstanceMaxCount), the beam failure recovery (BFR) process is triggered. The terminal device can initiate a random access procedure for beam failure recovery. For example, the terminal device may initiate a random access process in a primary cell (primary cell, PCell) or a primary secondary cell (primary secondary cell, SpCell). If the beamFailureDetectionTimer times out, or the terminal device receives a reconfiguration of at least one of the parameters SSB/CSI-RS resources for beam failure detection, beamFailureInstanceMaxCount and beamFailureDetectionTimer, reset BFI_COUNTER to zero.
如果终端设备随机接入成功，则可以将BFI_COUNTER重置为零，停止beamFailureDetectionTimer，以及认为波束失败恢复过程成功完成。If the terminal device random access is successful, it may reset BFI_COUNTER to zero, stop the beamFailureDetectionTimer, and consider the beam failure recovery procedure to be successfully completed.
为了保证终端设备的通信质量，终端设备可以对RLM和BFD进行周期性测量，相应地，终端设备就有对应的功率消耗。为了降低终端设备的功耗，协议中引入对RLM和BFD进行测量放松的方案。In order to ensure the communication quality of the terminal device, the terminal device may periodically measure the RLM and BFD, and accordingly, the terminal device has corresponding power consumption. In order to reduce the power consumption of the terminal equipment, the protocol introduces a solution for RLM and BFD measurement relaxation.
对RLM和BFD进行测量放松的方案适用于各种网络架构。例如，DC架构、载波聚合(carrier aggregation，CA)架构、独立组网(standalone，SA)架构等。DC架构例如可以包括以下中的至少一种：EN-DC、NE-DC和NR-DC。CA架构例如可以包括以下中的至少一种：NR intra-band CA、NR inter-band CA。SA架构例如可以为NR SA。下面以DC架构为例，对DC架构进行描述。The scheme of measurement relaxation for RLM and BFD is applicable to various network architectures. For example, a DC architecture, a carrier aggregation (carrier aggregation, CA) architecture, an independent networking (standalone, SA) architecture, and the like. The DC architecture may include, for example, at least one of: EN-DC, NE-DC and NR-DC. The CA architecture may include at least one of the following, for example: NR intra-band CA, NR inter-band CA. The SA architecture can be, for example, NR SA. The DC architecture is described below by taking the DC architecture as an example.
DC架构DC architecture
在某些通信***(如5G***)中，网络的部署方式可以包括两种。一种是SA模式，即5G基站直接连接到核心网，可独立工作。另一种是非独立部署(non-standalone，NSA)模式，即5G基站不直接连接到核心网，需要依赖于其他通信***的基站(如4G基站)接入到核心网。在NSA模式下，终端设备可以与4G基站或者5G基站通信，该模式也称为DC模式。In some communication systems (such as 5G systems), the network deployment methods can include two types. One is the SA mode, that is, the 5G base station is directly connected to the core network and can work independently. The other is the non-standalone (NSA) mode, that is, the 5G base station is not directly connected to the core network, but needs to rely on base stations of other communication systems (such as 4G base stations) to access the core network. In NSA mode, terminal devices can communicate with 4G base stations or 5G base stations, which is also called DC mode.
DC模式可以增强网络的移动性能及增加用户吞吐量。在该架构中，终端设备可以同时与两个基站(如5G基站和4G基站)保持连接，其中一个基站可以称为主基站或者主节点(master node，MN)，另一个基站可以称为辅基站或者辅节点(secondary node，SN)。The DC mode can enhance the mobile performance of the network and increase the user throughput. In this architecture, the terminal device can maintain connection with two base stations (such as 5G base station and 4G base station) at the same time, one of which can be called the primary base station or master node (MN), and the other base station can be called the secondary base station Or secondary node (secondary node, SN).
根据不同空口和核心网的排列组合，以及双连接时控制面(control plane，CP)所应用的无线接入技术，通信***的双连接架构可以分为EN-DC架构、NE-DC架构和NR-DC架构等。其中，E代表演进的通用地面无线接入(evolveduniversal terrestrial radio access，E-UTRA)，即4G无线接入网；N代表NR，即5G新无线。According to the arrangement and combination of different air interfaces and core networks, and the wireless access technology applied in the control plane (CP) during dual connectivity, the dual connectivity architecture of the communication system can be divided into EN-DC architecture, NE-DC architecture and NR architecture. -DC architecture, etc. Among them, E stands for evolved universal terrestrial radio access (evolved universal terrestrial radio access, E-UTRA), that is, 4G radio access network; N stands for NR, that is, 5G new radio.
下面结合图2，对本申请实施例的DC架构进行描述。双连接架构下，连接态的终端设备会被配置一个主小区组(master cell group，MCG)和一个辅小区组(secondary cell group，SCG)。主节点下面的小区可以称为MCG，辅节点下面的小区可以称为SCG。其中，MCG可以指终端设备首先发起随机接入的小区所在的组。The following describes the DC architecture of the embodiment of the present application with reference to FIG. 2 . Under the dual-connection architecture, terminal devices in the connected state will be configured with a master cell group (MCG) and a secondary cell group (SCG). A cell under the master node may be called an MCG, and a cell under the secondary node may be called an SCG. Wherein, the MCG may refer to the group where the cell in which the terminal device initiates random access first belongs.
在MCG下，可能会有很多个小区。其中，用于发起初始接入的小区可以称为主小区(primary cell，PCell)。PCell是MCG里面最主要的小区。MCG还可以包括一个或多个辅小区(secondary cell，SCell)。MCG下的PCell和MCG下的SCell可以通过CA技术联合在一起。Under MCG, there may be many cells. Wherein, the cell used to initiate the initial access may be called a primary cell (primary cell, PCell). PCell is the most important cell in MCG. The MCG may also include one or more secondary cells (secondary cell, SCell). The PCell under the MCG and the SCell under the MCG can be combined through the CA technology.
类似地，在SCG下也会有一个最主要的小区，称为主辅小区(primary secondary，PSCell)。该PSCell可以理解为在SCG下发起初始接入的小区。SCG还可以包括一个或多个SCell。SCG下的PSCell和SCG下的Scell可以通过CA技术联合在一起。Similarly, there will also be a primary cell under the SCG, which is called a primary secondary cell (PSCell). The PSCell can be understood as a cell that initiates initial access under the SCG. An SCG may also include one or more SCells. The PSCell under the SCG and the Scell under the SCG can be combined through the CA technology.
由于很多信令只在PCell和PSCell上发送，为方便描述，下文可以将PCell和PSCell合称为sPCell。换句话说，下文中的sPCell可以表示PCell和/或PSCell。Since many signalings are only sent on the PCell and the PSCell, for the convenience of description, the PCell and the PSCell may be collectively referred to as sPCell hereinafter. In other words, sPCell hereinafter may represent PCell and/or PSCell.
基于前文的描述可知，决定终端设备是否进行测量放松的一个关键因素是：终端设备是否处于低移动状态。但是，在DC架构下，针对网络设备(如主节点和/或辅节点)如何获取终端设备的移动状态，目前还没有明确的方案。Based on the foregoing description, it can be seen that a key factor for determining whether the terminal device performs measurement relaxation is: whether the terminal device is in a low mobility state. However, under the DC architecture, there is currently no clear solution for how network devices (such as primary nodes and/or secondary nodes) obtain the mobility status of terminal devices.
为了解决上述问题，本申请提供一种基于双连接的通信方法。本申请实施例提供了一种双连接网络下进行RLM放松和/或BFD放松的方案，即当终端设备满足低移动性准则时，由网络设备(主节点和/或辅节点)通过第一指令指示终端设备进行RLM放松和/或BFD放松。该第一指令可以基于第一信息得到。该第一信息可用于指示终端设备满足低移动性准则。该第一信息可以由终端设备确定，并发送至主节点和/或辅节点。例如，在一些实施例中，在接收到该第一指令之前，终端设备可以先确定自己是否满足低移动性准则，并在满足低移动性准则的情况下，向主节点和/或辅节点发送该第一信息，以使主节点和/或辅节点获知终端设备是否处于低移动状态。或者，在另一些实施例中，该第一信息也可以由主节点和/或辅节点自主确定。In order to solve the above problems, the present application provides a communication method based on dual connectivity. The embodiment of this application provides a solution for RLM relaxation and/or BFD relaxation in a dual-connection network, that is, when the terminal device meets the low mobility criterion, the network device (primary node and/or secondary node) passes the first instruction Instruct the terminal device to perform RLM relaxation and/or BFD relaxation. The first instruction can be obtained based on the first information. The first information may be used to indicate that the terminal device satisfies the low mobility criterion. The first information may be determined by the terminal device and sent to the primary node and/or the secondary node. For example, in some embodiments, before receiving the first instruction, the terminal device may first determine whether it satisfies the low mobility criterion, and if it satisfies the low mobility criterion, send the The first information is used to enable the primary node and/or the secondary node to know whether the terminal device is in a low mobility state. Alternatively, in some other embodiments, the first information may also be determined autonomously by the primary node and/or the secondary node.
下面结合图3，对本申请实施例提供的基于双连接的通信方法进行详细描述。该双连接网络可以包 括主节点和辅节点。图3所示的方法包括步骤S310～S330。步骤S310～S320描述的是终端设备确定并向网络设备(主节点和/或辅节点)发送第一信息(指示终端设备满足低移动性准则)的过程。在一些实施例中，可以省去步骤S310～S320。在这种情况下，可以由网络设备自主确定终端设备是否处于低移动状态。The dual connectivity-based communication method provided by the embodiment of the present application will be described in detail below with reference to FIG. 3 . The dual-connected network may include primary nodes and secondary nodes. The method shown in FIG. 3 includes steps S310-S330. Steps S310-S320 describe the process of the terminal device determining and sending the first information (indicating that the terminal device meets the low mobility criterion) to the network device (primary node and/or secondary node). In some embodiments, steps S310-S320 may be omitted. In this case, the network device can autonomously determine whether the terminal device is in a low mobility state.
在步骤S310、终端设备确定终端设备是否满足低移动性准则。In step S310, the terminal device determines whether the terminal device meets the low mobility criterion.
低移动性准则的判断方式可以与上文描述的RRM测量放松中的低移动性准则的判断方式类似。例如，终端设备可以对服务小区(如主小区和/或主辅小区)的信号测量结果进行评估，以确定终端设备是否满足低移动性准则。The judging manner of the low mobility criterion may be similar to the judging manner of the low mobility criterion in the RRM measurement relaxation described above. For example, the terminal device may evaluate the signal measurement results of the serving cell (such as the primary cell and/or the primary-secondary cell) to determine whether the terminal device satisfies the low mobility criterion.
在一些实施例中，终端设备可以对MCG中的小区(如主小区或辅小区)进行测量，并基于信号测量结果，确定终端设备是否满足低移动性准则。例如，终端设备可以对MCG中的主小区进行测量，并基于主小区的信号测量结果确定终端设备是否满足低移动性准则，也就是说，低移动性准则是否被满足可以由终端设备对主小区的信号测量结果确定。In some embodiments, the terminal device may measure a cell (such as a primary cell or a secondary cell) in the MCG, and determine whether the terminal device meets the low mobility criterion based on the signal measurement result. For example, the terminal device can measure the primary cell in the MCG, and determine whether the terminal device satisfies the low mobility criterion based on the signal measurement result of the primary cell, that is, whether the low mobility criterion is met can be determined by the terminal device The signal measurement results are determined.
在另一些实施例中，终端设备可以对SCG中的小区(如主辅小区或辅小区)进行测量，并基于信号测量结果，确定终端设备是否满足低移动性准则。例如，终端设备可以对SCG中的主辅小区进行测量，并基于主辅小区的信号测量结果确定终端设备是否满足低移动性准则，也就是说，低移动性准则是否被满足可以由终端设备对主辅小区的信号测量结果确定。In some other embodiments, the terminal device may measure a cell in the SCG (such as a primary-secondary cell or a secondary cell), and determine whether the terminal device satisfies the low mobility criterion based on the signal measurement result. For example, the terminal device can measure the primary-secondary cell in the SCG, and determine whether the terminal device meets the low mobility criterion based on the signal measurement result of the primary-secondary cell, that is, whether the low mobility criterion is satisfied can be determined by the terminal device The signal measurement results of the primary and secondary cells are determined.
以主小区和辅小区为例，终端设备可以仅对主小区的信号测量结果进行评估，或者，终端设备可以仅对辅小区的信号测量结果进行评估，或者，终端设备也可以同时对主小区和辅小区的信号测量结果进行评估。Taking the primary cell and the secondary cell as an example, the terminal device may only evaluate the signal measurement results of the primary cell, or the terminal device may only evaluate the signal measurement results of the secondary cell, or the terminal device may also evaluate both the primary cell and the secondary cell The signal measurement results of the secondary cell are evaluated.
在对信号测量结果进行评估时，终端设备可以使用低移动性准则参数对主小区和/或主辅小区的信号测量结果进行评估。低移动性准则参数可以包括t-SearchDeltaP和s-SearchDeltaP。终端设备可以判断主小区和/或主辅小区的信号测量结果在t-SearchDeltaP时间内是否小于门限值s-SearchDeltaP。如果主小区和/或主辅小区的信号测量结果在t-SearchDeltaP时间内小于门限值s-SearchDeltaP，则终端设备确定终端设备满足低移动性准则。如果主小区和/或主辅小区的信号测量结果在t-SearchDeltaP时间内不小于门限值s-SearchDeltaP，则终端设备确定终端设备不满足低移动性准则。When evaluating the signal measurement result, the terminal device may use the low mobility criterion parameter to evaluate the signal measurement result of the primary cell and/or the primary secondary cell. Low mobility criterion parameters may include t-SearchDeltaP and s-SearchDeltaP. The terminal device may determine whether the signal measurement result of the primary cell and/or the primary and secondary cells is less than the threshold s-SearchDeltaP within the time t-SearchDeltaP. If the signal measurement result of the primary cell and/or the primary and secondary cells is less than the threshold s-SearchDeltaP within the t-SearchDeltaP time, the terminal device determines that the terminal device meets the low mobility criterion. If the signal measurement result of the primary cell and/or the primary and secondary cells is not less than the threshold s-SearchDeltaP within the t-SearchDeltaP time, the terminal device determines that the terminal device does not meet the low mobility criterion.
主小区和辅小区的低移动性准则参数可以相同，也可以不同。例如，终端设备可以使用相同的低移动性准则参数分别对主小区和辅小区的信号测量结果进行评估。又例如，终端设备可以使用不同的低移动性准则参数分别对主小区和辅小区的信号测量结果进行评估。The low mobility criterion parameters of the primary cell and the secondary cell may be the same or different. For example, the terminal device may use the same low mobility criterion parameter to evaluate the signal measurement results of the primary cell and the secondary cell respectively. For another example, the terminal device may use different low mobility criterion parameters to evaluate the signal measurement results of the primary cell and the secondary cell respectively.
在一些实施例中，主小区和辅小区的低移动性准则参数可以由相同的节点配置。例如，主小区和辅小区的低移动性准则参数均由主节点配置，或者主小区和辅小区的低移动性准则参数均由辅节点配置。在另一些实施例中，主小区和辅小区的低移动性准则参数可以由不同的节点配置。例如，主小区的低移动性准则参数由主节点配置，辅小区的低移动性准则参数由辅节点配置。In some embodiments, the low mobility criterion parameters of the primary cell and the secondary cell may be configured by the same node. For example, both the low mobility criterion parameters of the primary cell and the secondary cell are configured by the primary node, or the low mobility criterion parameters of the primary cell and the secondary cell are both configured by the secondary node. In some other embodiments, the low mobility criterion parameters of the primary cell and the secondary cell may be configured by different nodes. For example, the low mobility criterion parameter of the primary cell is configured by the primary node, and the low mobility criterion parameter of the secondary cell is configured by the secondary node.
低移动性准则参数可以由主节点配置，也可以由辅节点配置，或者由主节点和辅节点同时配置。如图4和图5所示，在步骤S305、主节点可以向终端设备发送低移动性准则参数，即低移动性准则参数可以由主节点配置。The low mobility criterion parameter can be configured by the primary node, or by the secondary node, or by both the primary node and the secondary node. As shown in Fig. 4 and Fig. 5, in step S305, the master node may send the low mobility criterion parameter to the terminal device, that is, the low mobility criterion parameter may be configured by the master node.
如果低移动性准则参数由主节点配置，则终端设备可以使用该低移动性准则参数对主小区的信号测量结果进行评估。如果低移动性准则参数由辅节点配置，则终端设备可以使用该低移动性准则参数对主辅小区的信号测量结果进行评估。If the low mobility criterion parameter is configured by the primary node, the terminal device can use the low mobility criterion parameter to evaluate the signal measurement result of the primary cell. If the low mobility criterion parameter is configured by the secondary node, the terminal device can use the low mobility criterion parameter to evaluate the signal measurement result of the primary secondary cell.
举例说明，主节点可以向终端设备配置第一低移动性准则参数，该第一低移动性准则参数包括t-SearchDeltaP 1和s-SearchDeltaP 1。进一步地，终端设备可以对主小区的信号进行测量，并基于主小区的信号测量结果判断终端设备是否满足low-mobility准则。如果主小区的信号测量结果在t-SearchDeltaP1时间内小于门限值s-SearchDeltaP 1，则表示终端设备满足低移动性准则。否则，终端设备不满足低移动性准则。For example, the master node may configure a first low mobility criterion parameter to the terminal device, where the first low mobility criterion parameter includes t-SearchDeltaP 1 and s-SearchDeltaP 1. Further, the terminal device may measure the signal of the primary cell, and judge whether the terminal device satisfies the low-mobility criterion based on the signal measurement result of the primary cell. If the signal measurement result of the primary cell is less than the threshold value s-SearchDeltaP 1 within the t-SearchDeltaP1 time, it means that the terminal device meets the low mobility criterion. Otherwise, the terminal device does not satisfy the low mobility criterion.
辅节点可以向终端设备配置第二低移动性准则参数，该第二低移动性准则参数包括t-SearchDeltaP2和s-SearchDeltaP 2。进一步地，终端设备可以对辅小区的信号进行测量，并基于辅小区的信号测量结果判断终端设备是否满足low-mobility准则。如果辅小区的信号测量结果在t-SearchDeltaP 2时间内小于门限值s-SearchDeltaP 2，则表示终端设备满足低移动性准则。否则，终端设备不满足低移动性准则。The secondary node may configure the second low mobility criterion parameter to the terminal device, and the second low mobility criterion parameter includes t-SearchDeltaP2 and s-SearchDeltaP2. Further, the terminal device may measure the signal of the secondary cell, and judge whether the terminal device satisfies the low-mobility criterion based on the signal measurement result of the secondary cell. If the signal measurement result of the secondary cell is less than the threshold value s-SearchDeltaP 2 within t-SearchDeltaP 2, it means that the terminal device meets the low mobility criterion. Otherwise, the terminal device does not satisfy the low mobility criterion.
终端设备可以在主小区和辅小区中的一个小区的信号测量结果满足判定条件的情况下，确定终端设备满足低移动性准则。或者，终端设备也可以在主小区和辅小区的信号测量结果同时满足判定条件的情况下，确定终端设备满足低移动性准则。本申请实施例对此不做具体限定。这里的判定条件可以指信号测量结果在t-SearchDeltaP时间内小于门限值s-SearchDeltaP。The terminal device may determine that the terminal device satisfies the low mobility criterion when the signal measurement result of one of the primary cell and the secondary cell satisfies the determination condition. Alternatively, the terminal device may also determine that the terminal device satisfies the low mobility criterion when the signal measurement results of the primary cell and the secondary cell simultaneously meet the determination condition. This embodiment of the present application does not specifically limit it. The determination condition here may refer to that the signal measurement result is less than the threshold value s-SearchDeltaP within the time t-SearchDeltaP.
低移动性准则参数可以由网络设备通过信令无线承载(signaling radio bearer，SRB)来配置，该SRB例如可以为SRB1、SRB2和SRB3中的至少一种。例如，低移动性准则参数可以由主节点通过SRB1配置，或者，低移动性准则参数可以由辅节点通过SRB1或SRB2配置。The low mobility criterion parameter may be configured by a network device through a signaling radio bearer (signaling radio bearer, SRB), for example, the SRB may be at least one of SRB1, SRB2, and SRB3. For example, the low mobility criterion parameter may be configured by the primary node through SRB1, or the low mobility criterion parameter may be configured by the secondary node through SRB1 or SRB2.
本申请实施例中的信号测量结果可以包括以下中的至少一种：RSRP的测量结果、RSRQ的测量结果和SINR的测量结果。The signal measurement results in this embodiment of the present application may include at least one of the following: a measurement result of RSRP, a measurement result of RSRQ, and a measurement result of SINR.
在步骤S320、如果终端设备满足低移动性准则，则终端设备可以向主节点和辅节点中的至少一个节点发送第一信息。第一信息指示终端设备满足低移动性准则。第一信息可用于主节点和/或辅节点确定是否执行RLM放松和/或BFD放松。In step S320, if the terminal device satisfies the low mobility criterion, the terminal device may send first information to at least one of the primary node and the secondary node. The first information indicates that the terminal device satisfies a low mobility criterion. The first information may be used by the primary node and/or the secondary node to determine whether to perform RLM relaxation and/or BFD relaxation.
在一些实施例中，终端设备可以仅在满足低移动性准则的情况下，向主节点或辅节点发送第一信息。也就是说，如果终端设备不满足低移动性准则，则终端设备可以不向主节点或辅节点发送第一信息。主节点或辅节点接收到终端设备发送的第一信息后，可以确定终端设备处于低移动状态。In some embodiments, the terminal device may only send the first information to the primary node or the secondary node when the low mobility criterion is satisfied. That is, if the terminal device does not satisfy the low mobility criterion, the terminal device may not send the first information to the primary node or the secondary node. After receiving the first information sent by the terminal device, the primary node or the secondary node may determine that the terminal device is in a low mobility state.
在一些实施例中，终端设备也可以向主节点和辅节点同时发送第一信息，以使主节点和辅节点能够及时获知终端设备的移动状态。如果终端设备向主节点和辅节点均发送第一信息，则终端设备可以同时向主节点和辅节点发送第一信息，也可以先后向主节点和辅节点发送第一信息。In some embodiments, the terminal device may also send the first information to the primary node and the secondary node at the same time, so that the primary node and the secondary node can know the movement state of the terminal device in time. If the terminal device sends the first information to both the primary node and the secondary node, the terminal device may send the first information to the primary node and the secondary node at the same time, or may send the first information to the primary node and the secondary node successively.
在另一些实施例中，终端设备可以向主节点发送第一信息，以使主节点将该第一信息发送至辅节点；或者，终端设备可以向辅节点发送第一信息，以使辅节点将该第一信息发送至主节点。当然，在一些实施例中，接收到第一信息的节点也可以选择不向另一节点发送该第一信息，在这种情况下，终端设备是否执行RLM放松和/或BFD放松的决定可以由接收到第一信息的节点独立作出。该实施例提供的实现方式能够节省空口开销。In some other embodiments, the terminal device may send the first information to the primary node, so that the primary node sends the first information to the secondary node; or, the terminal device may send the first information to the secondary node, so that the secondary node will The first information is sent to the master node. Of course, in some embodiments, the node that receives the first information may also choose not to send the first information to another node. In this case, the decision of whether the terminal device performs RLM relaxation and/or BFD relaxation may be determined by Nodes that receive the first information do so independently. The implementation provided by this embodiment can save air interface overhead.
在向主节点或辅节点发送第一信息时，终端设备可以向配置低移动性准则参数的节点发送第一信息。例如，如果低移动性准则参数由主节点配置，则终端设备可以向主节点发送第一信息。又例如，如果低移动性准则参数由辅节点配置，则终端设备可以向辅节点发送第一信息。再例如，如果低移动性准则参数由主节点和辅节点配置，则终端设备可以向主节点和辅节点均发送第一信息。When sending the first information to the primary node or the secondary node, the terminal device may send the first information to the node configured with the low mobility criterion parameter. For example, if the low mobility criterion parameter is configured by the master node, the terminal device may send the first information to the master node. For another example, if the low mobility criterion parameter is configured by the secondary node, the terminal device may send the first information to the secondary node. For another example, if the low mobility criterion parameter is configured by the primary node and the secondary node, the terminal device may send the first information to both the primary node and the secondary node.
本申请实施例对主节点和辅节点之间传输第一信息的方式不做具体限定。作为一个示例，主节点和辅节点之间可以通过RRC信令传输第一信息。该RRC信令例如可以为节点间消息。该节点间消息例如可以为小区组配置信息(cell group configuration information，CG-ConfigInfo)或辅小区组配置信息(secondary cell group configuration information，SCG-ConfigInfo)等。作为另一个示例，主节点和辅节点之间可以通过Xn应用协议(Xn application protocol，XnAP)消息来传输第一信息。The embodiment of the present application does not specifically limit the manner of transmitting the first information between the primary node and the secondary node. As an example, the first information may be transmitted between the primary node and the secondary node through RRC signaling. The RRC signaling may be, for example, an inter-node message. The inter-node message may be, for example, cell group configuration information (CG-ConfigInfo) or secondary cell group configuration information (SCG-ConfigInfo). As another example, the first information may be transmitted between the primary node and the secondary node through an Xn application protocol (Xn application protocol, XnAP) message.
在一些实施例中，第一信息可以包含在第一消息中。该第一消息可以为测量上报(MeasurementReport)消息，或者，第一消息可以为UE辅助信息(UEAssistanceInformation)消息。换句话说，终端设备可以使用MeasurementReport消息上报第一信息，或者，终端设备可以使用UEAssistanceInformation消息上报第一信息。In some embodiments, the first information may be included in the first message. The first message may be a measurement report (MeasurementReport) message, or the first message may be a UE assistance information (UEAssistanceInformation) message. In other words, the terminal device may use the MeasurementReport message to report the first information, or the terminal device may use the UEAssistanceInformation message to report the first information.
该第一消息可以承载于SRB中。例如该第一消息可以承载于SRB1或SRB3中。例如，终端设备可以通过SRB1向MN发送第一信息。又例如，终端设备可以通过SRB1或SRB3向SN发送第一信息。The first message may be carried in the SRB. For example, the first message may be carried in SRB1 or SRB3. For example, the terminal device may send the first information to the MN through SRB1. For another example, the terminal device may send the first information to the SN through SRB1 or SRB3.
基于前文的描述可知，服务小区的信号质量也是影响终端设备是否进行测量放松的一个关键因素。本申请实施例对主节点和/或辅节点获取服务小区的信号质量的方式不做具体限定。在一些实施例中，主节点和/或辅节点可以基于RRM测量结果获取服务小区的信号质量。终端设备可以对服务小区进行RRM测量，并将RRM测量结果上报给主节点和/或辅节点。由于RRM测量结果中包括服务小区的信号质量以及至少一个相邻小区的信号质量，因此，主节点和/或辅节点可以基于RRM测量结果确定服务小区的信号质量。在另一些实施例中，终端设备可以向主节点和/或辅节点发送服务小区的信号质量。例如，终端设备可以在向主节点和/或辅节点发送第一信息的同时，向主节点和/或辅节点发送服务小区的信号质量。Based on the foregoing description, it can be seen that the signal quality of the serving cell is also a key factor affecting whether the terminal device performs measurement relaxation. The embodiment of the present application does not specifically limit the manner in which the primary node and/or the secondary node obtains the signal quality of the serving cell. In some embodiments, the primary node and/or the secondary node may acquire the signal quality of the serving cell based on the RRM measurement result. The terminal device can perform RRM measurement on the serving cell, and report the RRM measurement result to the primary node and/or the secondary node. Since the RRM measurement result includes the signal quality of the serving cell and the signal quality of at least one neighboring cell, the primary node and/or the secondary node may determine the signal quality of the serving cell based on the RRM measurement result. In some other embodiments, the terminal device may send the signal quality of the serving cell to the primary node and/or the secondary node. For example, the terminal device may send the signal quality of the serving cell to the primary node and/or the secondary node while sending the first information to the primary node and/or the secondary node.
本申请实施例中的服务小区可以是主小区组中的任意一个小区，如主小区组中的主小区或辅小区；或者，服务小区可以是辅小区组中的任意一个小区，如辅小区组中的主辅小区或辅小区。The serving cell in this embodiment of the application can be any cell in the primary cell group, such as the primary cell or the secondary cell in the primary cell group; or, the serving cell can be any cell in the secondary cell group, such as the secondary cell group The primary secondary cell or the secondary cell in the cell.
终端设备可以在发送第一信息的同时，向主节点和/或辅节点发送服务小区的信号质量，换句话说，第一信息和服务小区的信号质量可以携带在同一个消息中。举例说明，如果第一信息包含在第一消息中，则第一消息还可以包括第二信息，该第二信息用于指示终端设备的服务小区的信号质量。The terminal device may send the signal quality of the serving cell to the primary node and/or the secondary node while sending the first information. In other words, the first information and the signal quality of the serving cell may be carried in the same message. For example, if the first information is included in the first message, the first message may further include second information, where the second information is used to indicate the signal quality of the serving cell of the terminal device.
该第二信息可以包括主小区组中的至少一个小区的信号测量结果，和/或辅小区组中的至少一个小区的信号测量结果。主小区组中的至少一个小区的信号测量结果可以包括以下信息中的至少一种：主小区的信号测量结果，主小区组中的一个或多个辅小区的信号测量结果。辅小区组中的至少一个小区的信号测量结果可以包括：主辅小区的信号测量结果，辅小区组中的一个或多个辅小区的信号测量结 果。也就是说，第二信息可以包括以下信息中的至少一种：主小区的信号测量结果，主小区组中的一个或多个辅小区的信号测量结果，主辅小区的信号测量结果，或者，辅小区组中的一个或多个辅小区的信号测量结果。The second information may include a signal measurement result of at least one cell in the primary cell group, and/or a signal measurement result of at least one cell in the secondary cell group. The signal measurement result of at least one cell in the primary cell group may include at least one of the following information: a signal measurement result of the primary cell, and signal measurement results of one or more secondary cells in the primary cell group. The signal measurement result of at least one cell in the secondary cell group may include: the signal measurement result of the primary secondary cell, and the signal measurement result of one or more secondary cells in the secondary cell group. That is to say, the second information may include at least one of the following information: signal measurement results of the primary cell, signal measurement results of one or more secondary cells in the primary cell group, signal measurement results of the primary and secondary cells, or, Signal measurement results of one or more secondary cells in the secondary cell group.
为方便描述，下文将主小区组中的至少一个小区的信号测量结果称为主小区组的信号测量结果，将辅小区组中的至少一个小区的信号测量结果称为辅小区组的信号测量结果。For the convenience of description, the signal measurement result of at least one cell in the primary cell group is referred to as the signal measurement result of the primary cell group, and the signal measurement result of at least one cell in the secondary cell group is referred to as the signal measurement result of the secondary cell group .
如果终端设备仅向主节点发送第一信息，则终端设备可以将主小区组的信号测量结果以及辅小区组的信号测量结果发送给主节点。主节点可以将辅小区组的信号测量结果发送给辅节点。例如，如图5所示，在步骤S326，终端设备可以将第一信息、主小区的信号测量结果、主辅小区的信号测量结果、MCG中的辅小区的信号测量结果以及SCG中的辅小区的信号测量结果发送给主节点。在步骤S328，主节点可以将第一信息、主辅小区的信号测量结果以及SCG中的辅小区的信号测量结果发送给辅节点。If the terminal device only sends the first information to the master node, the terminal device may send the signal measurement results of the primary cell group and the signal measurement results of the secondary cell group to the master node. The primary node may send the signal measurement result of the secondary cell group to the secondary node. For example, as shown in FIG. 5, in step S326, the terminal device may send the first information, the signal measurement result of the primary cell, the signal measurement result of the primary secondary cell, the signal measurement result of the secondary cell in the MCG, and the secondary cell in the SCG The signal measurement results are sent to the master node. In step S328, the primary node may send the first information, the signal measurement results of the primary and secondary cells, and the signal measurement results of the secondary cells in the SCG to the secondary node.
如果终端设备仅向辅节点发送第一信息，则终端设备可以将主小区组的信号测量结果以及辅小区组的信号测量结果发送给辅节点。辅节点可以将主小区组的信号测量结果发送给主节点。例如，终端设备可以将第一信息、主小区的信号测量结果、主辅小区的信号测量结果、MCG中的辅小区的信号测量结果以及SCG中的辅小区的信号测量结果发送给辅节点。辅节点可以将第一信息、主小区的信号测量结果以及MCG中的辅小区的信号测量结果发送给主节点。If the terminal device only sends the first information to the secondary node, the terminal device may send the signal measurement result of the primary cell group and the signal measurement result of the secondary cell group to the secondary node. The secondary node may send the signal measurement result of the primary cell group to the primary node. For example, the terminal device may send the first information, the signal measurement result of the primary cell, the signal measurement result of the primary secondary cell, the signal measurement result of the secondary cell in the MCG, and the signal measurement result of the secondary cell in the SCG to the secondary node. The secondary node may send the first information, the signal measurement result of the primary cell, and the signal measurement result of the secondary cell in the MCG to the primary node.
如果终端设备向主节点和辅节点都发送第一信息，则终端设备可以将主小区组的信号测量结果发送给主节点，将辅小区组的信号测量结果发送给辅节点。例如，如图4所示，在步骤S322、终端设备可以将第一信息、主小区的信号测量结果以及MCG中的辅小区的信号测量结果发送给主节点。在步骤S324、终端设备可以将第一信息、主辅小区的信号测量结果以及SCG中的辅小区的信号测量结果发送给辅节点。当然，终端设备也可以将主小区组的信号测量结果以及辅小区组的信号测量结果同时发送给主节点和辅节点，本申请实施例对此不做具体限定。If the terminal device sends the first information to both the primary node and the secondary node, the terminal device may send the signal measurement result of the primary cell group to the primary node, and send the signal measurement result of the secondary cell group to the secondary node. For example, as shown in FIG. 4, in step S322, the terminal device may send the first information, the signal measurement result of the primary cell, and the signal measurement result of the secondary cell in the MCG to the primary node. In step S324, the terminal device may send the first information, the signal measurement result of the primary secondary cell, and the signal measurement result of the secondary cell in the SCG to the secondary node. Of course, the terminal device may also send the signal measurement results of the primary cell group and the signal measurement results of the secondary cell group to the primary node and the secondary node at the same time, which is not specifically limited in this embodiment of the present application.
主节点和/或辅节点接收到终端设备发送的第一信息后，可以确定终端设备是否进行RLM放松和/或BFD放松。例如，主节点和/或辅节点可以基于第一信息，确定终端设备是否进行RLM放松和/或BFD放松。又例如，主节点和/或辅节点可以基于第一信息以及服务小区的信号质量，确定终端设备是否进行RLM放松和/或BFD放松。After receiving the first information sent by the terminal device, the master node and/or the secondary node may determine whether the terminal device performs RLM relaxation and/or BFD relaxation. For example, the primary node and/or the secondary node may determine whether the terminal device performs RLM relaxation and/or BFD relaxation based on the first information. For another example, the primary node and/or the secondary node may determine whether the terminal device performs RLM relaxation and/or BFD relaxation based on the first information and the signal quality of the serving cell.
作为一个示例，主节点和/或辅节点可以在终端设备满足低移动性准则的情况下，确定终端设备进行RLM放松和/或BFD放松。在一些实施例中，主节点和/或辅节点可以在终端设备满足低移动性准则以及服务小区的信号质量满足预设条件的情况下，确定终端设备进行RLM放松和/或BFD放松。该预设条件可以是信号质量大于门限值。该门限值的类型以及配置方式可以与RRM测量放松中的门限值类似。为了简洁，此处不再赘述。As an example, the primary node and/or the secondary node may determine that the terminal device performs RLM relaxation and/or BFD relaxation when the terminal device meets the low mobility criterion. In some embodiments, the primary node and/or the secondary node may determine that the terminal device performs RLM relaxation and/or BFD relaxation when the terminal device meets the low mobility criterion and the signal quality of the serving cell meets a preset condition. The preset condition may be that the signal quality is greater than a threshold. The type and configuration manner of the threshold may be similar to the threshold in RRM measurement relaxation. For the sake of brevity, details are not repeated here.
如果主节点和/或辅节点确定终端设备可以进行RLM放松和/或BFD放松，则主节点和/或辅节点可以向终端设备发送第一指令。如图3-图5所示，在步骤S330、主节点和/或辅节点可以向终端设备发送第一指令，该第一指令用于指示终端设备进行测量放松。该测量放松例如可以为RLM放松和/或BFD放松。If the master node and/or the secondary node determines that the terminal device can perform RLM relaxation and/or BFD relaxation, the master node and/or the secondary node may send the first instruction to the terminal device. As shown in FIGS. 3-5 , in step S330, the primary node and/or the secondary node may send a first instruction to the terminal device, where the first instruction is used to instruct the terminal device to perform measurement relaxation. The measurement relaxation may eg be RLM relaxation and/or BFD relaxation.
在一些实施例中，网络设备在向终端设备发送第一指令时，还可以向终端设备指示测量放松的类型，如是进行RLM放松，还是进行BFD放松，或者同时进行RLM放松和BFD放松。当然，测量放松的类型也可以是协议中默认的，或者终端设备和网络设备之间也可以约定测量放松的类型。如果网络设备没有向终端设备指示测量放松的类型，则终端设备可以对约定的或默认的测量类型进行放松。In some embodiments, when the network device sends the first instruction to the terminal device, it may also indicate to the terminal device the type of measurement relaxation, such as RLM relaxation, BFD relaxation, or both RLM relaxation and BFD relaxation. Of course, the type of measurement relaxation may also be the default in the protocol, or the type of measurement relaxation may also be agreed upon between the terminal device and the network device. If the network device does not indicate the type of measurement relaxation to the terminal device, the terminal device may relax the agreed or default measurement type.
在接收到第一指令后，终端设备可以确定是否启动RLM放松和/或BFD放松。作为一个示例，终端设备在接收到第一指令之后，可以直接启动RLM放松和/或BFD放松。作为另一个示例，终端设备可以根据终端设备自身的实现，决定启动或不启动RLM放松和/或BFD放松。After receiving the first instruction, the terminal device may determine whether to start RLM relaxation and/or BFD relaxation. As an example, after receiving the first instruction, the terminal device may directly start RLM relaxation and/or BFD relaxation. As another example, the terminal device may decide to enable or disable RLM relaxation and/or BFD relaxation according to the implementation of the terminal device itself.
如果终端设备进行RLM放松，则终端设备可以对主小区组和/或辅小区组中的小区进行RLM放松。例如，终端设备可以对主小区组中的至少一个小区(如PCell和/或PSCell)进行RLM放松。如果终端设备进行BFD放松，则终端设备可以对主小区组和/或辅小区组中的小区进行BFD放松。例如，终端设备可以对主小区组或辅小区组中的至少一个小区(如PCell，PSCell和SCell中的至少一个)进行BFD放松。If the terminal device performs RLM relaxation, the terminal device may perform RLM relaxation on cells in the primary cell group and/or the secondary cell group. For example, the terminal device may perform RLM relaxation on at least one cell (such as PCell and/or PSCell) in the primary cell group. If the terminal device performs BFD relaxation, the terminal device may perform BFD relaxation on cells in the primary cell group and/or the secondary cell group. For example, the terminal device may perform BFD relaxation on at least one cell (such as at least one of PCell, PSCell, and SCell) in the primary cell group or the secondary cell group.
