Description

LBT监测失败的处理方法、装置和系统 技术领域
本发明涉及通信领域，特别涉及一种LBT监测失败的处理方法、装置和系统。
背景技术
无线链路失败(Radio Link Failuere，RLF)是通信标准化研究中关注的热门话题。
在新无线(NR)中，当以下条件满足时，会触发无线链路失败的检测：定时器T 310超时，随机接入过程失败且定时器T 311未运行，以及无线链路控制(RLC)失败。其中，定时器T 310和T 311的定义可以参考现有标准。
图1是随机接入过程的示意图，如图1所示，当终端设备没有接收到随机接入响应或者竞争解决未成功时，计数器“PREAMBLE_TRANSMISSION_COUNTER”加1。当该计数器的值为“preambleTransMax+1”时，终端设备向上层指示“随机接入问题”。
在发生了无线链路失败的情况下，如果终端设备没有配置双连接(Dual Connectivity，DC)，或终端设备配置了DC且无线链路失败发生在主小区组(MCG)，则终端设备认为是主小区组无线链路失败。这种情况下，终端设备可以留在连接态，选择一个合适的小区并进行连接重建。如果确定无线链路失败后的一定时间内，未找到合适的小区，终端设备可以进入空闲态。如果终端配置了DC且无线链路失败发生在辅小区组(SCG)，则终端设备认为是辅小区组无线链路失败。这种情况下，终端设备可以通过辅小区组失败信息过程，向网络设备报告该失败。
另一方面，频率资源问题一直以来也是通信技术讨论中重要的课题之一。为了解决频率资源问题，除了提高资源利用率，第三代合作伙伴计划(3GPP)也尝试使用更多的频带，包括未授权频段(unliciensed band)。为了在未授权频段上提供3GPP服务，引入了以下机制：先听后说(Listen Before Talk，LBT)，发现信号测量定时配置(Discovery RS Measurement Timing Configuration，DMTC)。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现，当使用未授权频段为终端设备提供服务时，由于网络设备和终端设备在进行通信前需要进行信道监听，确定信道是否空闲。只有当信道空闲时，终端设备才能发送上行消息和上行数据等，这对终端设备的行为会产生影响。此外，在未授权频段的随机接入过程中，媒体接入控制(Medium Access Control，MAC)子层向低层(物理层)指示发送随机接入前导码后，由于LBT失败，使得物理层放弃当次的前导码传输。放弃前导码传输后，终端设备的行为不清晰。这可能会影响随机接入成功率以及连接态下终端设备的业务。
为了解决上述问题中的至少一个或者解决其他类似问题，本发明实施例提供了一种LBT监测失败的处理方法、preamble的发送方法、装置和系统。

执行资源选择；
触发信道选择或者BWP切换；
触发无线链路失败；
触发RRC连接重建；
进行计数器维护。
根据本发明实施例的第五方面，提供了一种配置方法，其中，所述方法包括：

根据本发明实施例的第八方面，提供了一种网络设备，其中，所述网络设备包括前述第六方面所述的装置。
根据本发明实施例的第九方面，提供了一种通信系统，所述通信系统包括前述第七方面所述的终端设备和前述第八方面所述的网络设备。

终端设备202可以向网络设备201发送数据，例如使用免授权传输方式。网络设备201可以接收一个或多个终端设备202发送的数据，并向终端设备202反馈信息(例如确认ACK/非确认NACK)信息，终端设备202根据反馈信息可以确认结束传输过程、或者还可以再进行新的数据传输，或者可以进行数据重传。
下面结合附图对本发明的各种实施方式进行说明。这些实施方式只是示例性的，不是对本发明的限制。
实施例1
本实施例提供了一种随机接入前导码的发送方法，该方法应用于终端设备。图3是本实施例的随机接入前导码的发送方法的示意图，请参照图3，该方法包括：
步骤301：终端设备的媒体接入控制(MAC)层确定第一数量的用于发送前导码(preamble)的随机接入传输机会(RO)或者选择与用于发送前导码的RO有关的下行参考信号；
步骤302：所述终端设备的物理层根据所述第一数量的RO或者所述下行参考信 号确定第二数量的RO，所述第一数量和所述第二数量都大于1。
在本实施例的一个实施方式中，终端设备的MAC层可以确定多个传输机会，由此，终端设备的物理层可以获得该多个传输机会，并在该多个传输机会的至少一个上发送preamble。由于增加了传输机会，终端设备可以执行多LBT监测，增加了发送preamble的机会。在该实施方式中，上述第一数量和上述第二数量均大于1。并且，上述第一数量和上述第二数量可以相同也可以不同。
在本实施例中，以LBT监测为例进行说明，该LBT监测机制也可以替换为其他用于信道忙闲评估的机制，例如空闲信道评估(CCA)等，本实施例不限于此。
在本实施例的另一个实施方式中，终端设备的MAC层没有确定上述传输机会，而是指示选择的下行参考信号，该下行参考信号与上述传输机会有关，终端设备的物理层根据MAC层选择的该下行参考信号可以获得与其相关的多个传输机会，进而在该多个传输机会发送preamble，终端设备可以执行多LBT监测，增加了发送preamble的机会。在本实施方式中，上述第二数量大于1。
在本实施例中，终端设备的物理层可以根据前述第一数量的RO或者前述下行参考信号确定上述第二数量的RO，也可以进一步参考其他规则或准则确定该第二数量的RO，本实施例不限于此。
在本实施例中，上述下行参考信号可以是同步信号/广播信道块(SSB)，也可以是信道状态信息参考信号(CSI-RS)，或者是两者的结合，但本实施例不限于此，该下行参考信号也可以具有其他名称，或者借用当前标准的名称，增加适用于本实施例的方法的上述功能。
在本实施例的步骤301中，终端设备的物理层确定上述第一数量的RO，可以有以下方法：
方法一：
终端设备的MAC层选择第三数量的SSB和/或CSI-RS，对应每个选择的SSB和/或CSI-RS确定一个RO，得到所述第一数量的RO。
在这个方法中，MAC层可以选择多个SSB和/或CSI-RS，对应于每个选择的SSB和/或CSI-RS，确定一个相应的RO，从而得到多个RO。由于SSB的RO和CSI-RS的RO可能有重叠，因此，上述第三数量大于上述第一数量，并且第一数量大于1。
方法二：
终端设备的MAC层选择一个SSB或CSI-RS，确定选择的SSB或CSI-RS所关联的第一数量的RO。
在这个方法中，MAC层仅选择一个SSB或CSI-RS，对应于选择的SSB或CSI-RS，根据配置确定多个RO(第一数量的RO)，这里的多个RO(第一数量的RO)可能是上述选择的SSB或CSI-RS对应的所有RO，可以是从选择的SSB或CSI-RS对应的所有RO中选择出的部分RO，本实施例对此不作限制。此外，对于具体的选择方法，本实施例也不限制，例如可以基于网络设备规定的原则，也可以基于实现。此外，该方法适用于一个SSB或CSI-RS关联了多个RO的情况。
方法三：
如果终端设备处于空闲态(idle)或非激活态(inactive)，并且终端设备被配置了第一数量的初始带宽部分(BWP)，则终端设备的MAC层可以在每个初始BWP上确定一个RO，由此得到上述第一数量的RO。
在这个方法中，终端设备被配置了多个BWP，MAC层可以在每个初始BWP上确定一个RO，由此可以得到多个RO(第一数量的RO)。并且，该方法适用于单激活BWP场景，也就是说，只有LBT监测成功并且发送了preamble的初始BWP是激活的BWP。
方法四：
如果终端设备处于连接态(connected)，终端设备的MAC层可以在每个配置的BWP上确定一个RO。
当前标准中，一个小区(cell)上最多有四个BWP，其中一个为激活状态，则MAC层可以在这四个BWP上分别确定一个RO，得到四个RO(第一数量的RO)。该方法也适用于单激活BWP场景，如果LBT监测成功的RO在激活的BWP上，则终端设备可以在该激活的BWP上传输preamble，如果LBT监测成功的RO不在激活的BWP上，则终端设备可以在LBT监测成功的BWP上传输preamble，完成随机接入过程中，终端设备可以回到激活的BWP上，也可以留在传输preamble的BWP上，确定该BWP为激活的BWP。
方法五：
终端设备的MAC层在第一数量的聚合的载波上分别确定一个RO。该方法适用于载波聚合的场景，MAC层可以在多个聚合的载波上分别确定一个RO，从而得到 多个RO(第一数量的RO)。
方法六：
终端设备的MAC层对每个随机接入过程确定一个RO。该方法适用于并行随机接入的情况，对于每个随机接入过程确定一个RO，由此得到多个RO(第一数量的RO)。
方法七：
终端设备的MAC层在每个激活的BWP上确定一个RO。该方法适用于多激活BWP的场景，对于每个激活的BWP确定一个RO，由此得到多个RO(第一数量的RO)。
以上方法可以单独使用，也可以结合使用，本实施例不作限制。
在本实施例的步骤302中，在终端设备的物理层确定了多个RO(第二数量的RO)的情况下，该物理层还可以确定进行LBT监测的RO，也即为哪个或哪些RO执行LBT监测。
在一个实施方式中，物理层可以对上述第二数量的RO全部进行LBT监测。在本实施方式中，如果一个以上的RO的LBT监测都成功，物理层可以在所有成功的RO上都进行preamble的传输，或者从上述成功的RO中选择一部分(一个或多个)进行preamble的传输。
在另一个实施方式中，物理层可以从上述第二数量RO中选择一部分RO进行LBT监测。在本实施方式中，如果这一部分RO的LBT都成功，则物理层可以在这一部分RO上都进行preamble的传输，或者从上述成功的RO中选择一部分(一个或多个)进行preamble的传输。
在又一个实施方式中，物理层可以按照时间顺序对上述第一数量的RO进行LBT监测，直到满足一定的条件(称为第一条件)，例如规定数量(称为第四数量，可以是一个或多个)的LBT成功，或者对上述第二数量的RO全部进行了LBT监测。在本实施方式中，如果上述规定数量的LBT都成功，则物理层可以在所有成功的RO上进行preamble的传输，或者从中选择一部分(一个或多个)进行preamble的传输。
以上三种实施方式只是举例说明，具体采用哪种方式可以取决于网络设备的配置，或者基于标准规定，也可以取决于终端设备自己的实现，本实施例不作限制。
在本实施例的步骤302中，在终端设备的物理层确定了多个RO(第二数量的RO) 的情况下，该终端设备还可以确定启动RAR的接收窗口。在现有标准中，MAC层完成随机接入资源选择(确定了随机接入的资源和前导码)、随机接入传输(计算目标接收功率和RA-RNTI，如果需要)等步骤后，在确定的随机接入资源的最后一个符号后的一个特定的PDCCH occasion上启动接收随机接入响应(RAR)的窗口。在本实施例中，由于终端设备确定了多个RO，因此终端设备还需要确定何时启动接收RAR的窗口(称为RAR的接收窗口)。
在本实施例中，终端设备可以根据前述第一数量的RO(也即MAC层确定的RO)或者根据前述第二数量的RO(也即物理层确定的RO)启动RAR的接收窗口。
在一个实施方式中，终端设备可以确定一个RAR的接收窗口，也即维护一个RAR的接收窗口，可以有以下几种方法。
方法一：
如果终端设备的物理层仅在一个RO上进行了preamble的传输，则启动RAR的接收窗口的RO为该传输了preamble的RO。
在这个方法中，MAC层确定了一个或一个以上的RO，当MAC层指示物理层进行preamble的传输时，物理层仅在一个RO上进行preamble的传输，则终端设备在进行了preamble传输的RO上启动RAR的接收窗口。
方法二：
如果终端设备的物理层在多个RO上进行了preamble的传输，则启动RAR的接收窗口的RO为该多个RO中的第一个或最后一个RO。
在这个方法中，MAC层确定了一个或一个以上的RO，当MAC层指示物理层进行preamble的传输时，物理层在多个RO上进行了preamble的传输，则终端设备在进行了preamble传输的RO中的第一个OR或者最后一个RO上启动RAR的接收窗口。
在这个方法中，如果终端设备在进行了preamble传输的第一个RO上启动了RAR的接收窗口，则终端设备还可以在其后进行了preamble传输的RO上重启RAR的接收窗口，或者扩展RAR的接收窗口的窗长，或者停止当前RAR的接收窗口并启动一个新的RAR的接收窗口。
上述方法一和方法二都只考虑了进行preamble传输的RO。
方法三：
如果只有一个RO的LBT监测成功，则启动RAR的接收窗口的RO为LBT监测成功的RO。
在这个方法中，如果只有一个LBT监测成功的RO，则终端设备在该LBT监测成功的RO上启动RAR的接收窗口。
方法四：
如果多个RO的LBT监测成功，则启动RAR的接收窗口的RO为LBT监测成功的RO中第一个或最后一个RO。
在这个方法中，如果有多个LBT监测成功的RO，则终端设备可以在LBT监测成功的RO中的第一个RO或者最后一个RO上启动RAR的接收窗口。
在这个方法中，如果终端设备在LBT监测成功的第一个RO上启动RAR的接收窗口，则该终端设备还可以在其后每个LBT监测成功的RO上重启RAR的接收窗口，或者扩展RAR的接收窗口的窗长，或者停止当前RAR的接收窗口并启动一个新的RAR的接收窗口。
上述方法三和方法四考虑了所有LBT监测成功的RO。
方法五：
如果只有一个RO进行了LBT监测，则启动RAR的接收窗口的RO为进行了LBT监测的RO。
在这个方法中，如果只有一个RO进行了LBT监测，则终端设备可以在进行了LBT监测的RO上启动RAR的接收窗口。
方法六：
如果多个RO进行了LBT监测，则启动RAR的接收窗口的RO为进行了LBT监测的RO中第一个或最后一个RO。
在这个方法中，如果有多个RO进行了LBT监测，则终端设备可以在进行了LBT监测RO中的第一个RO或者最后一个RO上启动RAR的接收窗口。
在这个方法中，如果终端设备在进行了LBT监测的第一个RO上启动RAR的接收窗口，则该终端设备还可以在其后每个进行了LBT监测的RO上重启RAR的接收窗口，或者扩展RAR的接收窗口的窗长，或者停止当前RAR的接收窗口并启动一个新的RAR的接收窗口。
上述方法五和方法六考虑了所有进行了LBT监测的RO。
方法七：
如果终端设备的MAC层确定了一个RO，则启动RAR的接收窗口的RO为终端设备的MAC层确定的RO。
在这个方法中，如果MAC层只提供了一个RO，则终端设备可以在MAC层提供的RO上启动RAR的接收窗口。
方法八：
如果终端设备的MAC层确定了多个RO，则启动RAR的接收窗口的RO为终端设备的MAC层确定的RO中第一个或最后一个RO。
在这个方法中，如果MAC层提供了多个RO，则终端设备可以在MAC层提供的RO中的第一个RO或者最后一个RO上启动RAR的接收窗口。
在这个方法中，如果终端设备在MAC层提供的第一个RO上启动RAR的接收窗口，则该终端设备还可以在其后每个MAC层提供的RO上重启RAR的接收窗口，或者扩展RAR的接收窗口的窗长，或者停止当前RAR的接收窗口并启动一个新的RAR的接收窗口。
上述方法七和方法八考虑了所有MAC层提供的RO。
在另一个实施方式中，终端设备也可以确定多个RAR的接收窗口，也即维护多个RAR的接收窗口，可以有以下几种方法：
方法一：
如果终端设备的物理层在多个RO上进行了preamble的传输，则所述终端设备在每个或每组传输了所述前导码的RO上启动一个RAR的接收窗口，且在每组RO上启动一个RAR接收窗口的情况下，启动所述RAR的接收窗口的RO为传输了所述前导码的所述多个RO的第一个或最后一个RO。
在这个方法中，考虑了进行了preamble传输的RO，当MAC层指示物理层进行preamble的传输时，物理层在多个RO上进行了preamble的传输，则终端设备在每个进行了preamble传输的RO上启动RAR的接收窗口，或者终端设备可以对进行了preamble传输的RO进行分组，并在每组上启动一个RAR的接收窗口。
在这个方法中，分组规则可以是：每个SSB或CSI-RS对应的RO为一组，或者，每个信道或BWP上的RO为一组，或者，每个小区上的RO为一组。但本实施例不限于此，也可以根据其他规则对进行了preamble传输的RO进行分组。
方法二：
如果多个RO的LBT监测成功，则所述终端设备在每个或每组LBT监测成功的RO上启动一个RAR的接收窗口，且在每组RO上启动一个RAR接收窗口的情况下，启动所述RAR的接收窗口的RO为LBT监测成功的所述多个RO的第一个或最后一个RO。
在这个方法中，考虑了所有LBT监测成功的RO，如果有多个LBT监测成功的RO，则终端设备可以在每个LBT监测成功的RO上启动RAR的接收窗口，或者终端设备可以对LBT监测成功的RO进行分组，并在每组上启动一个RAR的接收窗口。
在这个方法中，分组规则与方法一相同，此处省略说明。
方法三：
如果多个RO进行了LBT监测，则所述终端设备在每个或每组进行了LBT监测的RO上启动一个RAR的接收窗口，且在每组RO上启动一个RAR接收窗口的情况下，启动所述RAR的接收窗口的RO为进行了LBT监测的所述多个RO的第一个或最后一个RO。
在这个方法中，考虑了所有进行了LBT监测的RO，如果有多个进行了LBT监测的RO，则终端设备可以在每个进行了LBT监测的RO上启动RAR的接收窗口，或者终端设备可以对进行了LBT监测的RO进行分组，并在每组上启动一个RAR的接收窗口。
在这个方法中，分组规则与方法一相同，此处省略说明。
方法四：
如果终端设备的MAC层确定了多个RO，则所述终端设备在每个或每组所述终端设备的MAC层确定的RO上启动一个RAR的接收窗口，且启动所述RAR的接收窗口的RO为所述终端设备的MAC层确定的所述多个RO的第一个或最后一个RO。
在这个方法中，考虑了所有MAC层提供的RO，如果有多个MAC层提供的RO，则终端设备可以在每个MAC层提供的RO上启动RAR的接收窗口，或者终端设备可以对MAC层提供的RO进行分组，并在每组上启动一个RAR的接收窗口。
在这个方法中，分组规则与方法一相同，此处省略说明。
通过本实施例的前述方法启动RAR的接收窗口，在存在多个RO情况下，可以确定RAR的接收窗口的启动的时机，从而维护RAR的接收窗口。基于该方法，终端 侧和网络侧对RAR的接收窗口的维护有一致理解，这样网络设备可以在RAR的接收窗口内完成RAR的传输，提高了随机接入成功率。
本实施例以preamble的发送为例进行了说明，但本实施例不限于此，相同的方法也可以应用于msg.3的传输，例如，为多个msg.3确定多个传输机会，维护对应msg.3的一个或多个竞争解决计时器。此处不再赘述。
通过本实施例的方法，增加了发送preamble的机会，并解决了preamble的传输机会增加的情况下产生的各种问题。
实施例2
本实施例提供了一种LBT监测失败的处理方法，该方法应用于终端设备，该方法可以和实施例1的方法结合使用，也可以单独使用，其中与实施例1内容相同之处不再重复说明。
图4是本实施例的LBT监测失败的处理方法的示意图，请参照图4，该方法包括：
步骤401：终端设备的物理层进行LBT监测，所述物理层认为LBT监测失败时向MAC层或者RRC层指示LBT监测失败或者preamble传输放弃或LBT检测实例失败；
步骤402：所述终端设备的MAC层或者RRC层根据所述指示进行以下处理的至少一种：执行资源选择；触发信道选择或者BWP切换；触发无线链路失败；触发RRC连接重建；进行计数器维护。
在本实施例的步骤401中，物理层可以在以下条件的至少一个满足的情况下认为LBT监测失败：
条件一：
一次LBT监测结果为忙碌。
在这个条件，当物理层进行了一次LBT监测后，如果确定忙碌，则认为LBT监测失败。其可以将LBT监测失败的信息或者preamble传输放弃的信息指示给MAC层或者RRC层，或者不进行上述指示，而是自己决定后续处理。如实施例1中所述，此处不再赘述。
条件二：
针对终端设备的MAC层一次指示的preamble的传输机会(RO)的一次或多次LBT监测结果都忙碌。
在这个条件中，MAC层有可能指示(或称为确定)一次RO，物理层针对该RO执行一次或多次(并行或串行)LBT监测，如果都确定忙碌，则认为LBT监测失败。
条件三：
针对一段时间内的多次LBT监测，LBT监测结果为忙碌的实例数达到第一数量。
在这个条件中，物理层可以在某段时间内执行多次LBT监测，确认忙碌的次数达到一定数量，认为LBT监测失败。
条件四：
对于多次LBT监测，LBT监测结果为忙碌的比例达到第一比例。
在这个条件中，物理层可以执行多次LBT监测，确认忙碌的次数与执行LBT监测的总次数达到一个比例，认为LBT监测失败。
条件五：
LBT监测结果为忙碌的实例数达到第二数量，在第一定时器的计时时间内，LBT监测结果为空闲的实例数未达到第三数量，其中，所述第一定时器是在所述LBT监测结果为忙碌的实例数达到第二数量时启动的。
在这个条件中，LBT实例是指执行一次LBT监测的情况，也即，条件一满足的情况下，认为一个LBT实例的监测结果为失败。
条件六：
在第二定时器超时后，LBT监测结果为忙碌的实例数达到第四数量，其中，所述第二定时器是在一个LBT实例的监测结果为忙碌时启动的。
在这个条件中，LBT实例的概念与前述相同，此处省略说明。
条件七：
在一个信道或BWP上，针对一段时间内的多次LBT监测，LBT监测结果为忙碌的实例数达到第五数量。
条件八：
在一个信道或BWP上，对于多次LBT监测，LBT监测结果为忙碌的比例达到第二比例。
条件九：
在一个信道或BWP上，LBT监测结果为忙碌的实例数达到第六数量，在第三定时器的计时时间内，LBT监测结果为空闲的实例数未达到第七数量，其中，所述第三定时器是在所述LBT监测结果为忙碌的实例数达到第六数量时启动的。
条件十：
在一个信道或BWP上，在第四定时器超时后，LBT监测结果为忙碌的实例数达到第八数量，其中，所述第四定时器是在一个LBT实例的监测结果为忙碌时启动的。
条件十一：
针对一个SSB和/或CSI-RS，针对一段时间内的多次LBT监测，LBT监测结果为忙碌的实例数达到第九数量。
条件十二：
针对一个SSB和/或CSI-RS，对于多次LBT监测，LBT监测结果为忙碌的比例达到第三比例。
条件十三：
针对一个SSB和/或CSI-RS，LBT监测结果为忙碌的实例数达到第十数量，在第五定时器的计时时间内，LBT监测结果为空闲的实例数未达到第十一数量，其中，所述第五定时器是在所述LBT监测结果为忙碌的实例数达到第十数量时启动的。
条件十四：
针对一个SSB和/或CSI-RS，在第六定时器超时后，LBT监测结果为忙碌的实例数达到第十二数量，其中，所述第六定时器是在一个LBT实例的监测结果为忙碌时启动的。
上述条件七至条件十与前述条件三至条件六类似，与条件三至条件六不同的是，该LBT监测是针对某个信道或BWP进行的。在满足上述条件七至条件十中任意一个条件的情况下，终端设备的物理层还可以向MAC层提供LBT监测结果失败的信道或BWP的信息。
上述条件十一至条件十四与前述条件三至条件六类似，与条件三至条件六不同的是，该LBT监测是针对某个SSB和/或CSI-RS进行的。在满足上述条件十一至条件十四中任意一个条件的情况下，终端设备的物理层还可以向MAC层提供LBT监测结果失败的SSB的索引和/或CSI-RS的资源标识。
上述条件三、七、十一中的“一段时间”可以描述为时间间隔T或者周期T，本 实施例不限于此。
在本实施例的步骤402中，在接收到来自物理层的LBT监测失败的指示或者当前preamble的传输放弃的指示或者LBT检测实例失败的指示时，MAC层可以执行资源选择，例如，preamble传输计数器不增加且不进行功率爬升或者preamble传输计数器增加但不进行功率爬升。这里，preamble的传输放弃的指示也可以理解为LBT监测失败的指示，本实施例对此不作限制。
在本实施例中，考虑到在基于竞争的随机接入过程里，msg.3传输前，也会进行LBT监测，且msg.3的传输会维护竞争解决定时器，因此本实施例的该方法也可以应用于msg.3，即当LBT监测失败导致msg.3的传输取消时，不必等待竞争解决定时器超时，直接进行随机接入资源的选择。
通过本实施例的该方法，在LBT失败的情况下，终端设备可以不必等待RAR的接收窗口的时间，直接进行资源选择，从而加速了随机接入的进程，降低了终端设备的能耗。
在本实施例的步骤402中，在接收到来自物理层的LBT监测失败的指示或者当前preamble的传输放弃的指示或者LBT检测实例失败的指示时，MAC层可以执行信道选择或者BWP切换；或者MAC层也可以在第一条件满足的情况下触发信道选择或者BWP切换，这里的第一条件为前述条件七至条件十的至少一种，此处不再赘述。
在本实施例中，如前所述，终端设备的物理层还可以将LBT监测结果失败的信道或者BWP提供给MAC层，也即，终端设备的MAC层还可以接收来自物理层的LBT监测结果失败的信道或者BWP，以便进行上述条件的判定。
在本实施例中，一个BWP可能包括多个信道(例如连接状态下)，会出现一部分信道的LBT监测失败，而另外一部分信道的LBT监测成功的情况。在本实施例中，只要有LBT监测失败，就认为这个BWP上的LBT监测失败。
在本实施例中，当发生信道选择或BWP切换时，随机接入过程终止或结束；完成信道选择或BWP切换后，可以发起新的随机接入过程；或者允许随机接入过程中进行信道选择或BWP切换。
通过本实施例的该方法，在LBT监测失败或满足一定条件(第一条件)下，终端设备可以进行信道选择或BWP切换，从而避免一直在原本总是LBT监测失败的信 道或BWP上进行随机接入。这样，能为终端设备节能，并提供更好的用户体验。该方法适用于所有状态的终端设备，例如空闲态、非激活态和连接态。
在本实施例的步骤402中，在接收到来自物理层的LBT监测失败的指示或者当前preamble的传输放弃的指示或者LBT检测实例失败的指示时，MAC层还可以触发无线链路失败或者间接地触发连接重建。后续终端设备的动作与当前标准中定义的发生无线链路失败后的动作相同，不同的只是触发条件。
例如，MAC层在收到上述指示时认为随机接入失败，如果该随机接入发生在某个特定小区(称为第一小区)，例如PCell或者PSCell，则终端设备向网络设备发送指示信息(称为第一指示信息)，通过该第一指示信息指示随机接入问题。关于上述PCell和PSCell的定义可以参考现有标准，在此统称为“主小区”。
再例如，MAC层也可以在第二条件满足的情况下认为随机接入失败，这里的第二条件为前述条件三至条件六的至少一种，此处不再赘述。
通过本实施例的该方法，在LBT监测失败的情况下，终端设备可以宣布“无线链路失败”或“信道繁忙”，从而避免一直在原本总是LBT监测失败的小区上或小区的一个信道上进行随机接入。这样，能为终端设备节能，并避免业务长时间中断、提供更好的用户体验。该方法适用于处于连接态的终端设备。
在本实施例的步骤402中，在接收到来自物理层的LBT监测失败的指示或者当前preamble的传输放弃的指示或者LBT检测实例失败的指示时，RRC层也可以触发无线链路失败或者触发RRC连接重建。
例如，RRC层可以在收到所述指示时发起连接重建过程，例如向网络设备发送第二指示信息，通过所述第二指示信息触发RRC连接重建。该第二指示信息中可以包括LBT监测失败的信息，具体形式本实施例不作限制。该第二指示信息可以包括在RRC重建请求消息(RRCReestablishmentRequest)里，用来重新建立与网络的RRC连接，但本实施例不限于此。
再例如，RRC层也可以在第三条件满足的情况下发起连接重建过程，触发终端设备的后续行为，如前所述，这里的第三条件可以是前述条件三至条件六的至少一种，此处不再赘述。
再例如，RRC层可以在收到上述指示后即认为无线链路失败，触发终端设备进行后续行为，可以参考现有标准中关于无线链路失败后终端设备的行为，此处省略说 明。
再例如，RRC层也可以在第四条件满足的情况下认为(或触发)无线链路失败，触发终端设备的后续行为。这里的第四条件可以是前述条件三至条件六的至少一种，此处不再赘述。
通过本实施例的该方法，在LBT监测失败或者满足一定条件(第三条件或第四条件)的情况下，终端设备可以向网络侧发起RRC连接重建过程或者认为无线链路失败，选择一个新的小区或同小区上的另外的信道，从而避免一直在原本总是LBT监测失败的小区上或小区的一个信道上进行随机接入。这样，能为终端设备节能，并避免业务长时间中断、提供更好的用户体验。该方法适用于处于连接态的终端设备。
在本实施例的步骤402中，在接收到来自物理层的LBT监测失败的指示或者当前preamble的传输放弃的指示或者LBT检测实例失败的指示时，终端设备的MAC层可以对计数器进行维护。
在本实施例中，在前述方法中，有可能LBT监测全部失败，导致preamble的传输被放弃，即没有进行preamble的传输，在这种情况下，如果不停止正在进行的随机接入，则可能导致终端设备的问题，例如，在终端设备处于连接态下，长时间甚至是没有尽头的随机接入尝试(进行随机接入选择，确定随机接入资源，指示物理层发送前导码，物理层进行LBT监测，LBT监测失败，RAR的接收窗到期后再次进行随机接入选择)，会导致业务中断，用户体验恶化，甚至电力耗尽。
为了解决上述问题，在本实施例中，还引入了计数器维护的机制。
例如，对于每个进行了LBT监测的RO，如果该RO的LBT监测失败，则preamble的传输计数器(如PREAMBLE_TRANSMISSION_COUNTER)加1。这里，LBT监测失败导致preamble的传输被放弃，关于LBT监测失败的情况将在下面的实施例中进行说明。
再例如，对于每个进行了LBT监测的RO，如果RO的LBT监测失败，并且RAR的接收窗口到期，则preamble的传输计数器(如PREAMBLE_TRANSMISSION_COUNTER)加1。这里，LBT监测失败导致preamble的传输被放弃，关于LBT监测失败的情况将在下面的实施例中进行说明。
通过以上机制，当LBT监测失败时，虽然没有进行preamble的传输，但重传计数器仍加1，这样可以限制随机接入尝试的次数，从而减小业务中断，改善用户体验， 节约终端耗电。
以上两种机制只是举例说明，本实施例不限于此。
再例如，还可以引入一个新的计数器，在随机接入过程发起时，该计数器置为1；在LBT监测失败的情况下，使该计数器的值加1，直到该计数器的值达到最大值，认为随机接入过程完成。这里，随机接入过程完成可能是成功的完成也可能是未成功的完成。
在本实施例中，“放弃(drop)”也可以用“取消(cancel)”或“失败(failed)”或“中断(interrupt)”或“挂起(suspend)”等相近的词语代替，均表示物理层应用指示的RO失败和/或没有向网络设备发送preamble。
在本实施例中，通过不同的实施方式说明了终端设备的物理层或MAC层或RRC层的处理，这些实施方式可以单独使用，也可以结合使用，本实施例不作限制。
通过本实施例的方法，在MAC层确认了一个或多个RO的情况下，当LBT监测失败时，提供了不同的处理机制，缩短了LBT监测失败后的响应时间，提高了随机接入的成功率。
实施例3
本实施例提供了一种配置方法，该方法应用于网络设备，其是对应实施例1和实施例2的方法的网络侧的处理，其中与实施例1和实施例2相同的内容不再重复说明。图5是本实施例的配置方法的示意图，如图5所示，该方法包括：
步骤501：网络设备为空闲态或者激活态的终端设备配置多个初始BWP，终端设备在每个所述初始BWP上确定一个RO。
在本实施例中，网络设备为终端设备配置多个初始BWP，终端设备可以在每个初始BWP上确定一个RO，具体的方法如实施例1所述，此处不再赘述。通过该方法，增加了preamble的传输机会，提高了随机接入的成功率。
在本实施例中，如实施例2所述，网络设备还可以接收终端设备发送的第一指示信息，根据该第一指示信息确认激活的BWP为传输上述第一指示信息的BWP，后续处理可以与现有标准相同，此处省略说明。
通过本实施例的方法，提高了随机接入的成功率。
实施例4
本实施例提供了一种随机接入前导码的发送装置，配置于终端设备，由于该装置解决问题的原理与实施例1的方法类似，其具体的实施可以参考实施例1，内容相同之处不再重复说明。
图6是本实施例的随机接入前导码的发送装置的示意图，如图6所示，本实施例的随机接入前导码的发送装置600包括：第一确定单元601和第二单元602。
第一确定单元601在终端设备的媒体接入控制(MAC)层确定第一数量的用于发送前导码(preamble)的随机接入传输机会(RO)或者选择与用于发送前导码的RO有关的下行参考信号；第二确定单元602在所述终端设备的物理层根据所述第一数量的RO或者所述下行参考信号确定第二数量的RO，所述第一数量和所述第二数量都大于1。
在本实施例中，所述第一确定单元601可以根据以下至少一种方法确定第一数量的RO：
所述终端设备的MAC层选择第三数量的同步信号/广播信道块(SSB)和/或信道状态信息参考信号(CSI-RS)，对应每个选择的SSB和/或CSI-RS确定一个RO，得到所述第一数量的RO；
所述终端设备的MAC层选择一个SSB或CSI-RS，确定选择的SSB或CSI-RS所关联的第一数量的RO；
