The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the embodiments of the present application. protected range.
特殊小区(Special Cell,SpCell)的BFRBFR of Special Cell (SpCell)
主小区(Primary Cell,PCell)是主小区组(Master Cell Group,MCG)侧的主小区,主辅小区(Primary Secondary Cell,PSCell)是辅小区组(Secondary Cell Group,SCG)侧的主小区。PCell和PSCell统称为SpCell。The Primary Cell (PCell) is the primary cell on the side of the Master Cell Group (MCG), and the Primary Secondary Cell (PSCell) is the primary cell on the side of the Secondary Cell Group (SCG). PCell and PSCell are collectively referred to as SpCell.
针对SpCell,标准化定义了其BFR。具体地,SpCell发生了波束失败的情况下,触发SpCell的波束失败恢复流程,其中,SpCell的波束失败恢复流程,可以通过以下流程来实现:终端设备通过随机接入的方式来告诉基站使用哪个下行波束来发送随机接入响应(Random Access Response,RAR),从而恢复下行波束。具体地,在随机接入流程中,终端设备向基站发送随机接入前导码(random access preamble),这里,随机接入前导码是按照同步信号块(SS/PBCH,SSB)配置的,终端设备按照以下方式选择需要发送的随机接入前导码:终端设备测量SSB的信号质量(例如参考信号接收功率(Reference Signal Received Power,RSRP)),根据SSB的信号质量选择满足阈值的SSB(SSB与信道状态信息-参考信号(Channel Status Information-Reference Signal,CSI-RS)之间是有关联关系的),选择该SSB对应的随机接入前导码,进一步,还选择该随机接入前导码对应的物理随机接入信道(Physical Random Access Channel,PRACH)资源。终端设备选择好随机接入前导码和PRACH资源后,在选择的PRACH资源上发送选择的随机接入前导码;基站在接收到随机接入前导码后,根据接收到的随机接入前导码或者随机接入前导码所在的PRACH资源可以确定使用哪个SSB关联的下行波束来反馈RAR。For SpCell, the standard defines its BFR. Specifically, when a beam failure occurs in the SpCell, the beam failure recovery process of the SpCell is triggered. The beam failure recovery process of the SpCell can be implemented through the following process: the terminal device tells the base station which downlink to use by means of random access beam to send a Random Access Response (Random Access Response, RAR), thereby restoring the downlink beam. Specifically, in the random access process, the terminal device sends a random access preamble (random access preamble) to the base station. Here, the random access preamble is configured according to a synchronization signal block (SS/PBCH, SSB), and the terminal device Select the random access preamble that needs to be sent in the following way: the terminal device measures the signal quality of the SSB (such as Reference Signal Received Power (RSRP)), and selects the SSB that satisfies the threshold according to the signal quality of the SSB (SSB and channel Status information-reference signal (Channel Status Information-Reference Signal, CSI-RS) is associated), select the random access preamble corresponding to the SSB, and further, select the physical address corresponding to the random access preamble Random access channel (Physical Random Access Channel, PRACH) resource. After the terminal device selects the random access preamble and the PRACH resource, it sends the selected random access preamble on the selected PRACH resource; after receiving the random access preamble, the base station sends the random access preamble or The PRACH resource where the random access preamble is located can determine which downlink beam associated with the SSB is used to feed back the RAR.
以下对SpCell的波束失败恢复流程中的主要步骤再进行说明:The main steps in the SpCell beam failure recovery process are explained below:
1、波束失败检测(Beam failure detection)。1. Beam failure detection.
终端设备的物理层监测物理下行控制信道(Physical Downlink Control Channel,PDCCH)的质量是否满足预定/配置的门限,作为示例,PDCCH的质量满足预定/配置的门限可以是指PDCCH的假设误块率(Hypothetical BLER)值小于等于预定/配置的门限。这里,终端设备的物理层通过以下方式监测PDCCH的质量:终端设备的物理层测量PDCCH对应的参考信号(如CSI-RS和/或SSB)的信号质量,若参考信号的信号质量满足预定/配置的门限,则认为参考信号对应的PDCCH的质量满足预定/配置的门限。The physical layer of the terminal device monitors whether the quality of the physical downlink control channel (Physical Downlink Control Channel, PDCCH) meets the predetermined/configured threshold. As an example, the quality of the PDCCH meets the predetermined/configured threshold may refer to the assumed block error rate of the PDCCH ( Hypothetical BLER) value is less than or equal to the predetermined/configured threshold. Here, the physical layer of the terminal device monitors the quality of the PDCCH in the following manner: the physical layer of the terminal device measures the signal quality of the reference signal (such as CSI-RS and/or SSB) corresponding to the PDCCH, if the signal quality of the reference signal meets the predetermined/configuration threshold, it is considered that the quality of the PDCCH corresponding to the reference signal meets the predetermined/configured threshold.
若终端设备的物理层监测到PDCCH的质量不满足预定/配置的门限,则终端设备的物理层向终端设备的MAC层上报一个波束失败事件(beam failure instance)。对一个MAC实体,每当物理层上报一个波束失败事件,其会为计数器BFI_COUNTER加1并重启定时器beamFailureDetectionTimer; 若在定时器beamFailureDetectionTimer运行期间内计数器BFI_COUNTER的值达到最大值,则终端设备认为发生了波束失败,触发波束失败恢复流程,这里,对于SpCell来说,触发发波束失败恢复流程也即是触发随机接入流程。If the physical layer of the terminal device detects that the quality of the PDCCH does not meet the predetermined/configured threshold, the physical layer of the terminal device reports a beam failure event (beam failure instance) to the MAC layer of the terminal device. For a MAC entity, whenever the physical layer reports a beam failure event, it will add 1 to the counter BFI_COUNTER and restart the timer beamFailureDetectionTimer; if the value of the counter BFI_COUNTER reaches the maximum value during the running of the timer beamFailureDetectionTimer, the terminal device considers that a beamFailureDetectionTimer has occurred A beam failure triggers a beam failure recovery process. Here, for the SpCell, triggering a beam failure recovery process is also triggering a random access process.
2、新候选波束(New candidate beam)的选择。2. Selection of new candidate beams.
终端设备测量参考信号(如CSI-RS和/或SSB)的信号质量,根据参考信号的信号质量选择满足预定/配置门限的参考信号。这里,由于参考信号与波束具有关联关系,因而“选择满足预定/配置门限的参考信号”也可以理解为“选择满足条件的新候选波束”。The terminal device measures the signal quality of reference signals (such as CSI-RS and/or SSB), and selects a reference signal that satisfies a predetermined/configured threshold according to the signal quality of the reference signals. Here, since the reference signal has an association relationship with the beam, "selecting a reference signal satisfying a predetermined/configured threshold" can also be understood as "selecting a new candidate beam satisfying a condition".
这里,如果终端设备没有选择到满足条件的新候选波束,则终端设备采用基于竞争的随机接入(contention-based random access)流程。Here, if the terminal device does not select a new candidate beam that satisfies the conditions, the terminal device adopts a contention-based random access (contention-based random access) process.
3、波束失败恢复请求。3. Beam failure recovery request.
终端设备向基站发起波束失败恢复请求,具体地,终端设备可以通过以下方式向基站发起波束失败恢复请求:The terminal device initiates a beam failure recovery request to the base station. Specifically, the terminal device can initiate a beam failure recovery request to the base station in the following ways:
方式一:终端设备选择新候选波束对应的随机接入前导码以及PRACH资源发起随机接入,基站根据随机接入前导码或者PRACH资源可以确定新候选波束。Method 1: The terminal device selects the random access preamble and PRACH resources corresponding to the new candidate beam to initiate random access, and the base station can determine the new candidate beam according to the random access preamble or the PRACH resource.
方式二:终端设备通过物理上行控制信道(Physical Uplink Control Channel,PUCCH)向基站上报其选择的新候选波束。Method 2: The terminal device reports the new candidate beam selected by it to the base station through a Physical Uplink Control Channel (PUCCH).
4、终端设备监测针对波束失败恢复请求的响应。4. The terminal device monitors the response to the beam failure recovery request.
若终端设备监测到基站发送的针对波束失败恢复请求的反馈信息或者新传调度信息,则终端设备认为波束失败恢复成功完成;若终端设备未监测到基站发送的针对波束失败恢复请求的反馈信息或者新传调度信息,则终端设备认为波束失败恢复尚未成功完成。If the terminal device detects the feedback information sent by the base station for the beam failure recovery request or the newly transmitted scheduling information, the terminal device considers that the beam failure recovery is successfully completed; if the terminal device does not monitor the feedback information sent by the base station for the beam failure recovery request or If the scheduling information is newly transmitted, the terminal device considers that the beam failure recovery has not been successfully completed.
辅小区(Secondary Cell,SCell)的BFRBFR of Secondary Cell (SCell)
MCG侧的辅小区和SCG侧的辅小区都称为SCell。针对SCell,标准化定义了其BFR。具体地,SCell发生了波束失败的情况下,触发SCell的波束失败恢复流程,其中,SCell的波束失败恢复流程,可以通过以下流程来实现:终端设备通过媒体接入控制(Media Access Control,MAC)控制单元(Control Element,CE)来告诉基站SCell发生了波束失败。Both the secondary cell on the MCG side and the secondary cell on the SCG side are called SCells. For SCells, BFRs are standardized and defined. Specifically, when a beam failure occurs on the SCell, the beam failure recovery process of the SCell is triggered. The beam failure recovery process of the SCell can be implemented through the following process: the terminal device passes the Media Access Control (MAC) A control element (Control Element, CE) informs the base station that a beam failure has occurred on the SCell.
用于波束失败恢复的MAC CE的类型有BFR MAC CE、截断BFR MAC CE(Truncated BFR MAC CE)。其中,BFR MAC CE和截断BFR MAC CE具有可变大小。为便于描述,以下将BFR MAC CE和截断BFR MAC CE简称为MAC CE。MAC CE包括一个比特图(bitmap)和N个波束失败恢复信息(beam failure recovery information),N为大于等于0的整数。如图2所示,MAC CE中的比特图为C

若小区中的第一TRP触发了波束失败恢复流程,则终端设备启动或者重启第一定时器,若在第一定时器运行期间内第一TRP触发的波束失败恢复流程尚未成功完成,且小区中的第二TRP触发了波束失败恢复流程,则终端设备认为该小区发生了波束失败,并触发该小区的波束失败恢复流程。可选地,若在第一定时器运行期间内,第一TRP触发的波束失败恢复流程成功完成(比如终端设备收到了网络设备的反馈信息或者收到了网络设备的新传调度信息),则终端设备停止第一定时器。If the beam failure recovery process triggered by the first TRP in the cell, the terminal device starts or restarts the first timer, if the beam failure recovery process triggered by the first TRP has not been successfully completed during the running period of the first timer, and the If the second TRP triggers the beam failure recovery process, the terminal device considers that the beam failure has occurred in the cell, and triggers the beam failure recovery process of the cell. Optionally, if the beam failure recovery process triggered by the first TRP is successfully completed during the running period of the first timer (for example, the terminal device receives feedback information from the network device or receives new scheduling information from the network device), the terminal The device stops the first timer.
在一些可选实施方式中,若第一TRP发生了波束失败,终端设备可以使用任意的上行资源或与第一TRP和/或第二TRP关联的上行资源来发生第一TRP的波束失败信息,可选地,第一TRP的波束失败信息承载在TRP BFR MAC CE中。In some optional implementation manners, if a beam failure occurs in the first TRP, the terminal device may use any uplink resource or an uplink resource associated with the first TRP and/or the second TRP to generate the beam failure information of the first TRP, Optionally, the beam failure information of the first TRP is carried in the TRP BFR MAC CE.

本申请实施例的上述技术方案,可以直观的判断两个TRP是否都发生波束失败,进而判断小区是否发生了波束失败,为小区的波束失败恢复提供了依据。其中,通过第一定时器判断两个TRP是否都发生波束失败,有利于增加波束失败恢复的成功率。此外,终端设备通过使用未发生波束失败的TRP关联的上行资源来发送发生波束失败的TRP的波束失败信息,若在第一定时器运行期间内未收到反馈信息或者新传调度信息,说明未发生波束失败的TRP的信道质量也比较弱,则这种情况下,也可以认为小区发生了波束失败。通过上述技术方案可以减小波束失败恢复的整体时延。The above technical solutions of the embodiments of the present application can intuitively judge whether beam failures occur in both TRPs, and then determine whether beam failures occur in a cell, which provides a basis for recovering from beam failures in a cell. Wherein, the first timer is used to judge whether beam failure occurs in both TRPs, which is beneficial to increase the success rate of beam failure recovery. In addition, the terminal device sends the beam failure information of the TRP with beam failure by using the uplink resources associated with the TRP without beam failure. The channel quality of the TRP where the beam failure occurs is relatively weak, and in this case, it can also be considered that the beam failure occurs in the cell.
