5G NR***5G NR system
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的主要应用场景为：增强移动宽带(enhance mobile broadband，eMBB)、超可靠低时延通信(ultra reliable low latency communications，URLLC)、大规模机器类通信(massive machine type communication，mMTC)。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 are: enhanced mobile broadband (eMBB), ultra reliable low latency communications (URLLC), and massive machine type communication (mMTC).
eMBB仍然以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速。另一方面，由于eMBB可能部署在不同的场景中，比如室内，市区，农村等，其能力和需求的差别也比较大，所以不能一概而论，必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC 的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。eMBB still aims at users' access to multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, the capabilities and requirements are quite different, so it cannot be generalized, and detailed analysis must be combined with specific deployment scenarios. Typical applications of URLLC include: industrial automation, electric power automation, telemedicine operations (surgery), traffic safety guarantee, etc. The typical characteristics of mMTC include: high connection density, small data volume, delay-insensitive services, low cost and long service life of modules, etc.
为了尽快实现5G网络的部署和商业应用，3GPP在2017年12底前首先完成第一个5G版本，即LTE-NR双连接(LTE-NR dual connectivity，EN-DC)。EN-DC的网络部署和组网架构示意图，如图2所示：LTE***的网络设备作为主节点(master node，MN)，NR***的网络设备作为辅节点(secondary node，SN)。In order to realize the deployment and commercial application of 5G network as soon as possible, 3GPP first completed the first 5G version, namely LTE-NR dual connectivity (LTE-NR dual connectivity, EN-DC), before the end of December 2017. The schematic diagram of the network deployment and networking architecture of EN-DC is shown in Figure 2: the network equipment of the LTE system serves as the master node (MN), and the network equipment of the NR system serves as the secondary node (SN).
在EN-DC场景(参见图3示出的EN-DC的场景3A和场景3)中，MN(LTE eNB)主要用于实现无线资源控制(radio resource control，RRC)功能以及通向核心网(core network，CN)的控制面，SN(gNB)可以配置辅助的信令，例如信令无线承载3(signalling radio bearer 3，SRB3)，主要提供数据传输功能。In the EN-DC scenario (refer to scenario 3A and scenario 3 of EN-DC shown in Figure 3), the MN (LTE eNB) is mainly used to implement the radio resource control (radio resource control, RRC) On the control plane of the core network (CN), the SN (gNB) can configure auxiliary signaling, such as signaling radio bearer 3 (signalling radio bearer 3, SRB3), which mainly provides data transmission functions.
在Release 15后期，除了支持EN-DC外，还支持其他的DC形式，如NE-DC、5GC-EN-DC以及NR-DC等。EN-DC的网络架构如图4所示，从图4可以看出，在EN-DC的网络架构中，接入网络连接的核心网是EPC。图5和图6分别示出的是NGEN-DC和NE-DC的网络架构，从图5和图6可以看出，这些网络架构的接入网络连接的核心网是5GC。以上列举的各种类型的DC形式，可以统称为多RAT双连接(multi-RAT dual connectivity，MR-DC)。NR***也可以独立部署。In the later stage of Release 15, in addition to supporting EN-DC, it also supports other DC forms, such as NE-DC, 5GC-EN-DC, and NR-DC. The network architecture of the EN-DC is shown in Figure 4. It can be seen from Figure 4 that in the network architecture of the EN-DC, the core network connected to the access network is the EPC. Figures 5 and 6 show the network architectures of NGEN-DC and NE-DC respectively. It can be seen from Figures 5 and 6 that the core network connected to the access network of these network architectures is 5GC. Various types of DC forms listed above may be collectively referred to as multi-RAT dual connectivity (multi-RAT dual connectivity, MR-DC). NR systems can also be deployed independently.
MCG快速恢复MCG Quick Recovery
在Release 15中，当MCG侧发生RLF等问题时，会触发RRC连接重建过程。当SCG侧发生RLF等问题时，会触发SCGFailureInformation的上报过程。In Release 15, when a problem such as RLF occurs on the MCG side, the RRC connection re-establishment process will be triggered. When a problem such as RLF occurs on the SCG side, the reporting process of SCGFailureInformation will be triggered.
图7示出的是RRC连接重建过程。参见图7，在步骤S710，终端向网络设备发送RRC连接重建请求。网络设备收到该RRC连接重建请求消息之后，向终端发送RRC连接重建消息，以触发终端进行RRC连接重建。在RRC连接重建完成之后，终端向网络设备发送RRC重建完成消息。Figure 7 shows the RRC connection re-establishment process. Referring to FIG. 7, in step S710, the terminal sends an RRC connection reestablishment request to the network device. After receiving the RRC connection reestablishment request message, the network device sends an RRC connection reestablishment message to the terminal, so as to trigger the terminal to perform RRC connection reestablishment. After the RRC connection re-establishment is completed, the terminal sends an RRC re-establishment complete message to the network device.
RRC连接重建请求的配置信息如下：The configuration information of the RRC connection reestablishment request is as follows:

考虑到MCG发生失败，而SCG侧可能信号很好的场景，为了避免该场景下的RRC连接重建，降低业务中断，Release 16中引入快速MCG恢复(fast MCG recovery)功能。即当MCG发生RLF(目前，协议仅支持RLF触发快速MCG恢复)，通过SCG链路发送MCG失败信息(MCGFailureInformation)，以触发网络设备快速恢复MCG侧链路。MCG快速恢复，当且仅当接入层(access stratum，AS)安全激活且SRB2和至少一个SRB建立时才能触发。Considering the scenario where the MCG fails and the SCG side may have a good signal, in order to avoid RRC connection re-establishment in this scenario and reduce service interruption, Release 16 introduces the fast MCG recovery (fast MCG recovery) function. That is, when RLF occurs in the MCG (currently, the protocol only supports RLF triggering fast MCG recovery), the MCG failure information (MCGFailureInformation) is sent through the SCG link to trigger the network device to quickly restore the MCG side link. MCG fast recovery can be triggered if and only when access stratum (AS) security is activated and SRB2 and at least one SRB are established.
当MCG侧发生RLF，而SCG侧处于悬挂(suspend)状态或者处于PSCell改变(PSCell change)过程，则终端触发RRC连接重建过程。When the RLF occurs on the MCG side, and the SCG side is in the suspend state or in the PSCell change (PSCell change) process, the terminal triggers the RRC connection reestablishment process.
MCGFailureInformation可以通过SCG侧的split SRB1或者SRB3发送。仅当split SRB1没有配置，且配置了SRB3的情况下，终端才会以使用SRB3上报MCGFailureInformation。MCGFailureInformation can be sent through split SRB1 or SRB3 on the SCG side. Only when split SRB1 is not configured and SRB3 is configured, the terminal will use SRB3 to report MCGFailureInformation.
终端发送完MCG失败信息，可以启动一个定时器(或称guard timer)，等待网络设备响应。网络设备的响应消息可以是：同步重配置(reconfiguration with sync)或者RRC释放(RRC Release)。如果终端收到该响应消息，则终端停止该定时器。如果该定时器超时，则触发RRC连接重建过程。此时RRC连接重建请求中的原因(cause)值填写“其他失败(otherFailure)”。After sending the MCG failure message, the terminal can start a timer (or guard timer) and wait for the network device to respond. The response message of the network device may be: synchronous reconfiguration (reconfiguration with sync) or RRC release (RRC Release). If the terminal receives the response message, the terminal stops the timer. If the timer expires, an RRC connection re-establishment process is triggered. At this time, the cause (cause) value in the RRC connection reestablishment request is filled with "other Failure (otherFailure)".
终端的快速MCG恢复过程需要经过网络设备显示的配置才可以触发。该“显示的配置”指的是网络设备通过配置上文提到的定时器来暗示终端可以触发快速MCG恢复过程。例如，网络设备可以通过RRC专用信令配置该定时器。The rapid MCG recovery process of the terminal can only be triggered after the configuration displayed by the network device. The "explicit configuration" means that the network device hints that the terminal can trigger the fast MCG recovery process by configuring the above-mentioned timer. For example, the network device can configure the timer through RRC dedicated signaling.
下面示出了该定时器的配置信息，即RRC重配中的T316定时器。The configuration information of the timer is shown below, that is, the T316 timer in RRC reconfiguration.

Figure PCTCN2021143889-appb-000004
当快速MCG恢复被触发之后，终端发送MCGFailureInformation。在这种情况下，终端执行以下操作中的一种或多种：除SRB0外，悬挂MCG侧的SRB和数据无线承载(data radio bearer，DRB)上的传输；重置MCG MAC；保存来自MCG和SCG侧的测量配置，如果可能，继续按照MCG和SCG侧的测量配置进行测量。如果终端接收网络设备的响应消息，则终端恢复MCG侧的传输。After the fast MCG recovery is triggered, the terminal sends MCGFailureInformation. In this case, the terminal performs one or more of the following operations: except for SRB0, suspend the transmission on the SRB and data radio bearer (data radio bearer, DRB) on the MCG side; reset the MCG MAC; save the transmission from the MCG and SCG side measurement configurations, if possible, continue to perform measurements according to the MCG and SCG side measurement configurations. If the terminal receives the response message from the network device, the terminal resumes the transmission on the MCG side.
下面结合图8，对终端使用split SRB1，或者SRB3传输MCGFailureInformation消息的过程进行介绍。In the following, the process of transmitting the MCGFailureInformation message by the terminal using split SRB1 or SRB3 will be introduced in combination with FIG. 8 .
如果split SRB的分组数据汇聚协议(packet data convergence protocol，PDCP)复制 (PDCP duplication)功能被激活，则当检测到MCG失败时，没有必要切换到主路径(primaryPath)。如果split SRB的PDCP duplication功能没有被激活，则主路径隐含被配置成SCG侧的路径。在MCG恢复过程中或者RRC连接重建过程中，终端期待网络设备显示重配置主路径到MCG侧。If the packet data convergence protocol (PDCP duplication) function of the split SRB is activated, there is no need to switch to the primary path (primaryPath) when an MCG failure is detected. If the PDCP duplication function of the split SRB is not activated, the primary path is implicitly configured as the path on the SCG side. During the MCG recovery process or the RRC connection reestablishment process, the terminal expects the network device to display the reconfiguration primary path to the MCG side.
MCGFailureInformation消息的内容可以包含以下信息中的一种的多种：MCG侧可获取的测量结果；MCG链路失败原因；SCG侧可获取的测量结果；非服务小区(non-serving cell)的可获取的测量结果。The content of the MCGFailureInformation message may contain one or more of the following information: measurement results available on the MCG side; cause of MCG link failure; measurement results available on the SCG side; available on the non-serving cell (non-serving cell) measurement results.
前文提到，在Release快速MCG恢复过程中，MCGFailureInformation消息可以通过split SRB1在SCG上传输，或者通过SRB3在SCG上传输，无论哪种方式，MCGFailureInformation消息都是主节点(master node，MN)的RRC层产生的RRC分组数据单元(packet data unit，PDU)。As mentioned above, during the fast MCG recovery process of Release, the MCGFailureInformation message can be transmitted on the SCG through split SRB1, or on the SCG through SRB3. Either way, the MCGFailureInformation message is the RRC of the master node (master node, MN) The RRC packet data unit (packet data unit, PDU) generated by the layer.
SCG去激活SCG deactivation
Release 17引入了SCG去激活的概念。SCG去激活场景中，目前允许终端向SCG侧发起随机接入过程。例如，在接收到来自MN节点SCG激活命令之后，终端可以发起随机接入过程。目前暂时不支持终端自主向SCG侧发起随机接入过程。SCG去激活后，需要悬挂SCG侧的无线承载上的传输。Release 17 introduced the concept of SCG deactivation. In the SCG deactivation scenario, the terminal is currently allowed to initiate a random access process to the SCG side. For example, after receiving the SCG activation command from the MN node, the terminal may initiate a random access procedure. At present, it is not supported that the terminal independently initiates a random access process to the SCG side. After the SCG is deactivated, it is necessary to suspend the transmission on the radio bearer on the SCG side.
在引入快速MCG恢复技术时，还没有SCG去激活的概念，所以当MCG发生RLG的时候，可以直接利用SCG进行快速MCG恢复。但是，如前文所述，Release 17中引入了SCG去激活的概念。如果SCG被去激活，但是网络设备显示指示终端可以执行快速MCG恢复的定时器(即定时器T316)也被配置了。终端应当如何通过SCG支持快速MCG恢复是需要解决的问题。例如，如果SCG去激活的场景下支持快速MCG恢复，则由于需要激活SCG才能实现快速MCG恢复，SCG激活的过程会导致MCG快速恢复过程被延迟。此时，如果将定时器T316的时长设置成与SCG激活场景下的时长相同，显然是不合适。When the fast MCG recovery technology is introduced, there is no concept of SCG deactivation, so when RLG occurs in MCG, SCG can be directly used for fast MCG recovery. However, as mentioned earlier, Release 17 introduced the concept of SCG deactivation. If the SCG is deactivated, but the network device displays a timer indicating that the terminal can perform fast MCG recovery (ie timer T316) is also configured. How the terminal should support fast MCG recovery through the SCG is a problem to be solved. For example, if fast MCG recovery is supported in a scenario where the SCG is deactivated, the SCG activation process will delay the fast MCG recovery process because the SCG needs to be activated to achieve fast MCG recovery. At this time, it is obviously inappropriate to set the duration of the timer T316 to be the same as that in the SCG activation scenario.
针对上述问题，下面结合图9，对本申请实施例进行详细描述。图9是站在终端和网络设备交互的角度进行描述的。该终端例如可以是图1中的终端120，该网络设备例如可以是图1中的网络设备110。作为示例，该终端可以是处于双连接的终端，如处于MR DC配置的终端。In view of the above problems, the following describes the embodiment of the present application in detail with reference to FIG. 9 . FIG. 9 is described from the perspective of interaction between a terminal and a network device. The terminal may be, for example, terminal 120 in FIG. 1 , and the network device may be, for example, network device 110 in FIG. 1 . As an example, the terminal may be a terminal in dual connectivity, such as a terminal in MR DC configuration.
参见图9，在步骤S910，网络设备向终端发送第一定时器的配置信息。该配置信息例如可以承载在RRC信令中。该RRC信令例如可以是RRC专用信令。Referring to FIG. 9, in step S910, the network device sends configuration information of the first timer to the terminal. The configuration information may be carried in RRC signaling, for example. The RRC signaling may be RRC dedicated signaling, for example.
该第一定时器可以与快速MCG恢复或用于快速MCG恢复的MCG失败信息消息关 联。例如，第一定时器的配置可用于指示(隐含指示)终端支持快速MCG恢复。该第一定时器可用于确定SCG侧发起的快速MCG恢复过程是否超时。作为示例，该第一定时器可以是定时器T316。This first timer may be associated with Fast MCG Recovery or an MCG Failure Information message for Fast MCG Recovery. For example, the configuration of the first timer may be used to indicate (implicitly indicate) that the terminal supports fast MCG recovery. The first timer may be used to determine whether the fast MCG recovery process initiated by the SCG side times out. As an example, the first timer may be timer T316.
该第一定时器可以包括第一时长和第二时长。其中，第一时长可以与SCG的激活状态对应；第二时长可以与SCG的去激活状态对应。The first timer may include a first duration and a second duration. Wherein, the first duration may correspond to the activation state of the SCG; the second duration may correspond to the deactivation state of the SCG.
所谓“第一时长与SCG的激活状态对应”可以指：当终端利用SCG进行快速MCG恢复时，如果SCG处于激活状态，则第一定时器的时长采用第一时长。The so-called "the first duration corresponds to the activation state of the SCG" may refer to: when the terminal uses the SCG to perform fast MCG recovery, if the SCG is in the activation state, the duration of the first timer adopts the first duration.
所谓“第二时长与SCG的去激活状态对应”可以指：当终端利用SCG进行快速MCG恢复时，如果SCG处于去激活状态，则第一定时器的时长采用第二时长。The so-called "the second duration corresponds to the deactivation state of the SCG" may refer to: when the terminal uses the SCG to perform fast MCG recovery, if the SCG is in the deactivation state, the duration of the first timer adopts the second duration.
在一些实施例中，第二时长可以基于第一时长和时间偏移值确定。例如，第二时长可以等于第一时长与时间偏移值(offset)之和。该第一时长可以由网络设备配置。该时间偏移值可以由协议预定义。例如，该时间偏移值可以是协议预定义的固定值。或者，该时间偏移值可以由网络设备配置。例如，网络设备可以通过RRC信令(如RRC专用信令)。In some embodiments, the second duration may be determined based on the first duration and the time offset value. For example, the second duration may be equal to the sum of the first duration and a time offset value (offset). The first duration can be configured by a network device. The time offset value may be predefined by the protocol. For example, the time offset value may be a fixed value predefined by the protocol. Alternatively, the time offset value can be configured by a network device. For example, the network device may use RRC signaling (such as RRC dedicated signaling).
在另一些实施例中，第一时长和第二时长均可以由网络设备直接配置。例如，网络设备可以通过RRC信令(如RRC专用信令)直接配置第一时长和第二时长。In other embodiments, both the first duration and the second duration may be directly configured by the network device. For example, the network device may directly configure the first duration and the second duration through RRC signaling (such as RRC dedicated signaling).
在一些实施例中，终端可以通过split SRB1或SRB3发送MCGFailureInformation消息。In some embodiments, the terminal can send the MCGFailureInformation message through split SRB1 or SRB3.
例如，如果SCG处于被去激活状态且第一定时器被配置，则当MCG侧发生RLF时，终端的MCG RRC实体生成MCGFailureInformation消息。然后，终端的MCG RRC实体可以将MCGFailureInformation RRC PDU递交给终端的PDCP层，并由PDCP层将该MCGFailureInformation消息对应的PDCP PDU递交到终端的SCG RLC实体，最后递交到终端的SCG MAC实体。For example, if the SCG is in the deactivated state and the first timer is configured, when RLF occurs on the MCG side, the MCG RRC entity of the terminal generates an MCGFailureInformation message. Then, the MCG RRC entity of the terminal can submit the MCGFailureInformation RRC PDU to the PDCP layer of the terminal, and the PDCP layer submits the PDCP PDU corresponding to the MCGFailureInformation message to the SCG RLC entity of the terminal, and finally submits it to the SCG MAC entity of the terminal.
又如，如果SCG处于被去激活状态且第一定时器被配置，则当MCG侧发生RLF时，终端的MCG RRC实体将MCGFailureInformation RRC PDU递交给终端的SCG RRC实体，终端的SCG RRC实体将MCGFailureInformation消息封装在ULInformationTransferMRDC消息中，并通过SRB3进行发送。通过SRB3的协议栈处理(也就是SRB3 PDCP，RLC)将MCGFailureInformation消息递交到终端的SCG MAC实体。For another example, if the SCG is in the deactivated state and the first timer is configured, then when RLF occurs on the MCG side, the MCG RRC entity of the terminal submits the MCGFailureInformation RRC PDU to the SCG RRC entity of the terminal, and the SCG RRC entity of the terminal submits the MCGFailureInformation The message is encapsulated in the ULInformationTransferMRDC message and sent through SRB3. The MCGFailureInformation message is delivered to the SCG MAC entity of the terminal through the protocol stack processing of SRB3 (that is, SRB3 PDCP, RLC).
基于UL数据的到达，终端的SCG MAC实体会向SCG侧的PSCell发起随机接入过程。如果存在有效的专用随机接入资源则使用专用随机接入资源发起非竞争随机接入，否则发起竞争随机接入。Based on the arrival of UL data, the SCG MAC entity of the terminal will initiate a random access process to the PSCell on the SCG side. If there is a valid dedicated random access resource, use the dedicated random access resource to initiate non-contention random access, otherwise initiate contention random access.
在随机接入过程中，终端可以向SCG侧发送的消息3(MSG3)可以为包含小区无线 网络临时标识(cell radio network temporary identifier，C-RNTI)的MAC CE。该C-RNTI可以是SCG去激活前为终端分配的C-RNTI。如果随机接入成功完成，即终端接收到该C-RNTI加扰的物理下行控制信道(physical downlink control channel，PDCCH)，则可以认为随机接入成功完成。在这种情况下，终端可以确定(或认为)SCG被激活。上述消息3中还可以进一步包含发起随机接入过程的目的，例如快速MCG恢复。因此，该MAC CE中可以包含以下信息中的一种或多种：C-RNTI，随机接入的目的，推荐的切换目标小区的物理小区标识(physical cell identity，PCI)等。During the random access process, the message 3 (MSG3) that the terminal can send to the SCG side can be a MAC CE that includes a cell radio network temporary identifier (C-RNTI). The C-RNTI may be the C-RNTI allocated for the terminal before the SCG is deactivated. If the random access is successfully completed, that is, the terminal receives the physical downlink control channel (physical downlink control channel, PDCCH) scrambled by the C-RNTI, it can be considered that the random access is successfully completed. In this case, the terminal may determine (or consider) that the SCG is activated. The above message 3 may further include the purpose of initiating the random access procedure, such as fast MCG recovery. Therefore, the MAC CE may contain one or more of the following information: C-RNTI, purpose of random access, physical cell identity (PCI) of the recommended handover target cell, etc.
重新参见图9，在步骤S920，终端启动第一定时器。第一定时器基于一定的条件启动。在一些实施例中，第一定时器的启动条件可以包括终端已发送MCG失败信息消息；和/或终端确定SCG的随机接入成功(或终端确定SCG处于激活状态)。如果终端收到网络设备发送的针对MCG失败信息消息的响应消息，则终端可以停止定时器。如果定时器超时未接收网络设备发送的针对MCG失败信息消息的响应消息，则可以发起RRC连接重建过程。Referring to FIG. 9 again, in step S920, the terminal starts a first timer. The first timer is started based on certain conditions. In some embodiments, the start condition of the first timer may include that the terminal has sent an MCG failure information message; and/or the terminal determines that the random access to the SCG is successful (or the terminal determines that the SCG is in an activated state). If the terminal receives a response message to the MCG failure information message sent by the network device, the terminal may stop the timer. If the timer expires and no response message to the MCG failure information message sent by the network device is received, an RRC connection reestablishment process may be initiated.
