背景技术
在第五代(5 th-Generation，5G)移动通信系统中，若终端想采用非授权频段发送信号，则需要在发送信号之前监听该非授权频段是否被占用(或空闲)。如果没有被占用(或空闲)，则终端可以在该非授权频段进行信号的发送；如果该频段被占用，则终端在该非授权频段无法进行信号的发送，即先听后说(Listen-Before-Talk，LBT)失败。
终端在发生了LBT失败的情况下，可以将发生了LBT失败的事件告知给网络侧设备。然而若，对于终端如何将发生了LBT失败的事件告知给网络侧设备，目前并没有相关的解决方案。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本申请中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，本申请中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B和/或C，表示包含单独A，单独B，单独C，以及A和B都存在，B和C都存在，A和C都存在，以及A、B和C都存在的7种情况。
请参见图1，图1是本发明实施例可应用的一种网络系统的结构图，如图1所示，包括终端11和网络侧设备12，其中，终端11和网络侧设备12之间可以进行通信。
在本发明实施例中，终端11也可以称作用户设备(User Equipment，UE)。在实际应用中，终端11可以是手机、平板电脑(Tablet Personal Computer)、 膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等。网络侧设备12可以是基站、中继或接入点等。
为了方便理解，以下对本发明实施例涉及的一些内容进行说明：
一、新空口-非授权(New RAT Un-licensed，NR-U)。
在第五代(5 th-Generation，5G)移动通信系统中，UE若想采用非授权频段发送信号，UE在发送信号之前需要监听该频段是否被占用(或空闲)，如果没有被占用(或空闲)，则终端可以在该频段进行信号的发送；如果该频段被占用，则UE无法在该频段进行信号的发送，即先听后说(Listen-Before-Talk，LBT)失败。
若采用非授权频段进行数据的收发，则UE需要满足非授权频段的使用规则。根据非授权频段的使用规则，UE需要在特定的频率范围(如频率子带(frequency sub-channel))内进行LBT，只有在该特定频率范围，监听到非授权频段没有被占用，UE才能在该非授权频段进行信号的发送。而在5G移动通信系统中，1个特定的带宽部分(Bandwidth Part，BWP)或小区可能会配置多个频率子带。
UE会对LBT造成的上行发送失败进行检测，网络侧设备会对“上行拥塞失败”检测配置对应的定时器和/或计数器。如，在一定时间内(即定时器)上行发送失败的次数(即计数器)达到或超过网络侧设备配置的门限值，则UE可以判断发生了“上行拥塞失败”。
如果经过检测，UE在1个小区的1个BWP上发生了上行LBT失败，UE会变更其激活的BWP到该小区的其他BWP，触发随机接入过程，并将失败信息报告给网络侧。如果UE连续的在多个BWP上发生上行LBT失败，根据网络侧设备配置，UE可以变更BWP多次。通过变更BWP从而变更UE在NR-U的工作频点，从而找到频点没有拥塞的BWP。
二、BWP。
在5G移动通信系统中，终端可能只能支持一个比较小的工作带宽，如5兆赫兹(MHz)，而网络侧设备的一个小区会支持比较大的带宽，如100MHz，该比较大的带宽中用于终端工作的小带宽部分则认为是BWP。从终端配置的 角度，对于不同的终端功能，BWP可以作为是1个小区下的BWP。
三、复用优先级。
当UE接收到上行授权的时候，会根据该上行授权可以承载的数据量，将不同逻辑信道标识对应的数据复用在一起生成媒体接入控制(Medium Access Control，MAC)协议数据单元(Protocol Data Unit，PDU)发送。
在生成MAC PDU的过程中，各数据按照复用优先级顺序从高到低的顺序排序如下：
小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)MAC控制单元(Control Unit，CE)或上行公共控制信道(Uplink Common Control Channel，UL-CCCH)数据(C-RNTI MAC CE or data from UL-CCCH)；
配置授权确认MAC CE(Configured Grant Confirmation MAC CE)；
用于第一缓存状态报告(Buffer Status Report，BSR)的MAC CE，所述第一BSR为除包括用于填充的BSR之外的其他BSR(MAC CE for BSR,with exception of BSR included for padding)；
单入口功率余量报告(Power Headroom Report，PHR)MAC CE或多入口PHR MAC CE(Single Entry PHR MAC CE or Multiple Entry PHR MAC CE；)；
第一逻辑信道数据，所述第一逻辑信道为除UL-CCCH之外的逻辑信道(data from any Logical Channel,except data from UL-CCCH)；
用于推荐比特率查询的MAC CE(MAC CE for Recommended bit rate query)；
包括用于填充的BSR的MAC CE(MAC CE for BSR included for padding)。
以下对本发明实施例的LBT失败的处理方法进行说明。
参见图2，图2是本发明实施例提供的LBT失败的处理方法的流程图之一。本实施例的LBT失败的处理方法可以应用于终端。
如图2所示，LBT失败的处理方法可以包括以下步骤：
步骤201、在LBT失败的情况下，通过媒体接入控制MAC控制单元CE发送LBT失败信息。
在本实施例中，LBT失败信息可以用于指示所述终端至少发生了一次LBT失败。进一步地，LBT失败信息携带于MAC CE中。
具体实现时，终端每发生一次LBT失败，都可以通过MAC CE发送LBT失败信息。具体地，在LBT失败的情况下，终端可以发起随机接入过程，并在随机接入过程中向网络侧设备发送携带有LBT失败信息的MAC CE。这样，网络侧设备在接收到LBT失败信息之后，可以知道终端在激活的BWP上发生了LBT失败，从而可以指示终端变更工作频点。终端在变更工作频点后，可以在变更后的工作频点上重新进行LBT，在LBT成功的情况下，终端可以在非授权频段上进行上行发送，从而可以提高上行发送的成功率。
其中，终端可以通过变更激活的BWP变更工作频点，也可以通过变更小区变更工作频点，具体可根据实际情况确定，本发明实施例对此不作限定。
另外，若终端发起的随机接入过程类型是四步随机接入过程，则上述MAC CE可以携带于消息(Message，Msg)3中；若终端发起的随机接入过程类型是两步随机接入过程，则上述MAC CE可以携带于MsgA中。
在本实施例中，终端在LBT失败的情况下，可以通过MAC CE实现LBT失败信息的上报。进一步地，网络侧设备在接收到LBT失败信息之后，可以指示终端变更工作频点，从而可以在变更后的工作频点上重新进行LBT，进而可以提高终端上行发送的成功率。
在本实施例中，可选的，所述LBT失败信息可以包括以下任意一项：
逻辑信道标识，所述逻辑信道标识用于指示所述终端在带宽部分BWP上发生了LBT失败；
N个BWP的标识，所述终端在M个BWP上发生了LBT失败，所述M个BWP包括所述N个BWP，N为正整数，M为大于或等于N的正整数。
为方便理解，具体说明如下。
场景一、所述LBT失败信息包括逻辑信道标识(Logical Channel ID，LCID)。
对于场景一，所述LBT失败信息可以用于指示所述终端在激活的BWP上发生了LBT失败。这样，网络侧设备在获取到逻辑信道标识后，可以知道终端在激活的BWP上发生了LBT失败，从而可以指示终端变更工作频点。
需要说明的是，用于指示所述终端在带宽部分BWP上发生了LBT失败的逻辑信道标识可以由协议预定，或由网络侧配置，但不仅限于此。在实际 应用中，逻辑信道标识可以表现为逻辑信道编号。
场景二、所述LBT失败信息包括N个BWP的标识。
对于场景二，所述LBT失败信息可以用于指示所述终端至少在所述N个BWP上发生了LBT失败。
在场景二中，终端在M个BWP上发生了LBT失败，即终端发生了M次LBT失败的情况下，终端可以上报发生了LBT失败的M个BWP中的N个BWP的标识。其中，N可以小于或等M。可见，具体实现时，终端可以发送发生了LBT失败的BWP中的部分BWP的标识，或全部BWP的标识。
对于场景二，在N为1的情况下，可选的，所述N个BWP可以为以下任意一项：
第一BWP，所述终端在所述第一BWP上发生LBT失败的时间先于所述终端在所述M个BWP中其他BWP上发生LBT失败的时间；
第二BWP，所述终端在所述第二BWP上发生LBT失败的时间后于所述终端在所述M个BWP中其他BWP上发生LBT失败的时间。
所述终端在M个BWP上发生了LBT失败，即所述终端发生了M次LBT失败。
在所述N个BWP为所述第一BWP的情况下，具体实现时，终端可以选择上报M次LBT失败中首次LBT失败对应的BWP的标识，即第一BWP的标识。
在所述N个BWP为所述第二BWP的情况下，具体实现时，终端可以选择上报M次LBT失败中最后一次LBT失败对应的BWP的标识，即第二BWP的标识。
为方便理解，示例说明如下：
终端在BWP-1上发生LBT失败，变换到BWP-2，然后，在BWP-2上发起随机接入过程时，仍然发生LBT失败，变换到BWP-3。则UE在BWP-3上上报LBT失败信息时，BWP-1即为上述第一BWP，BWP-2即为上述第二BWP。
在N大于1的情况下，所述N个BWP可以是所述M个BWP中的仁义N个BWP。可选的，所述N个BWP的标识的排列顺序根据所述终端在所述 N个BWP上发生LBT失败的时间先后顺序确定。
也就是说，所述N个BWP的标识在所述LBT失败信息中的排列顺序可以根据所述终端在所述N个BWP上发生LBT失败的时间先后顺序确定。
可选的，第一实现方式中，可以将最早发生LBT失败的BWP的标识排列在最前，相应的，将最晚发生LBT失败的BWP的标识排列在最后。第二实现方式中，可以将最晚发生LBT失败的BWP的标识排列在最前，相应的，将最早发生LBT失败的BWP的标识排列在最后。
为方便理解，示例说明如下：
假设终端先后在BWP-1、BWP-2、BWP-3和BWP-4上发生了LBT失败，终端在BWP-4发生了LBT失败后，可以发送LBT失败信息。在实际应用中，可选的，终端可在该LBT失败信息中携带BWP-1、BWP-2和BWP-3的标识。
在该可选方式中，对于上述第一实现方式，BWP-1、BWP-2和BWP-3的标识在LBT失败信息中的排列先后顺序可以为：BWP-1的标识、BWP-2的标识和BWP-3的标识。
对于上述第而实现方式，BWP-1、BWP-2和BWP-3的标识在LBT失败信息中的排列先后顺序可以为：BWP-3的标识、BWP-2的标识和BWP-1的标识。
在本实施例中，MAC CE的格式与LBT失败信息的内容相关，说明如下。
对于上述第一场景，即所述LBT失败信息包括所述逻辑信道标识，可选的，所述MAC CE包括MAC子头；其中，所述LBT失败信息携带于所述MAC子头中。
具体实现时，用于携带所述LBT失败信息的MAC CE可以仅包括MAC子头(subheader)，可以不携带任何额外的MAC CE内容和MAC服务数据单元(Service Data Unit，SDU)内容，从而可以节省信令。
对于上述场景二，即所述LBT失败信息包括N个BWP的标识，可选的，所述MAC CE包括MAC子头和MAC CE内容；其中，所述N个BWP的标识携带于所述MAC CE内容中。
在所述MAC CE包括MAC子头和MAC CE内容的情况下，进一步的，所述MAC CE内容可以还包括指示域，所述指示域用于指示第一比特位是否 携带有BWP的标识；其中，所述第一比特位为所述MAC CE内容中位于第二比特位之后的比特位，所述第二比特位为所述指示域所占用的比特位。
这样，网络侧设备在读取MAC CE内容时，可以通过指示域，确定是否继续读取MAC CE内容中的剩余部分。具体地，若在指示域指示所述第一比特位携带有BWP的标识，则可以继续读取MAC CE内容中的剩余部分；否则，可以放弃读取MAC CE内容中的剩余部分，从而可以降低网络侧设备的运行负担。
在实际应用中，可选的，所述指示域可以为E域，当E域的取值为“0”时，指示所述第一比特位携带有BWP的标识；当取值为“1”时，所述第一比特位未携带有BWP的标识。
另外，在指示域指示所述第一比特位携带有BWP的标识时，MAC CE内容中剩余比特位可以保留，可以称之为保留(Reserved)比特位。
需要说明的是，在实际应用中，所述第二比特位和所述第一比特位可以连续，也可以非连续。所述第二比特位和所述第一比特位可以属于同一字节(Oct)，也可以属于不同的Oct。
另外，对于一个字节，字节中最左侧的比特位可以称为字节的第一个比特位，字节中最右侧的比特位可以称为字节的最后一个比特位，字节中最右侧的比特位位于字节中最左侧的比特位之后。对于上下排列的多个字节，最上侧的字节可以称为第一个字节，最下侧的字节可以称为最后一个字节，最下侧的字节中的比特位位于最上侧的字节中的比特位之后。
可见，通过在MAC CE设置该指示域，使网络侧设备可以确定MC CE内容中指示域的后续比特位是否还存在BWP的标识，在该指示域指示后续没有BWP的标识时，网络侧设备可以及时结束对BWP的标识的检测，从而可以节省网络侧设备的运行资源。
由上述内容可知，在本实施例中，用于携带LBT失败信息的MAC CE可以为以下之一：
第一格式的MAC CE，仅包括MAC子头；
第二格式的MAC CE，包括MAC子头和MAC CE内容。
需要说明的是，在实际应用中，终端可以通过上述任一种格式的MAC CE 携带LBT失败信息，具体可根据实际需求确定，本发明实施例对此不作限定。
在本实施例中，终端在上报携带有LBT失败信息的MAC CE时，可以将该MAC CE复用组包到MAC PDU中，通过MAC PDU上报。
可选的，在生成MAC协议数据单元PDU时，所述LBT失败信息的复用优先级满足以下任意一项：
所述LBT失败信息的复用优先级至少高于第一逻辑信道数据的复用优先级；
所述LBT失败信息的复用优先级与小区无线网络临时标识C-RNTI MAC CE的复用优先级相同；
所述LBT失败信息的复用优先级仅低于C-RNTI MAC CE的复用优先级；
所述LBT失败信息的复用优先级仅高于第一逻辑信道数据的复用优先级；
其中，所述第一逻辑信道为除上行公共控制信道之外的逻辑信道。
在生成MAC PDU时，其他数据的复用优先级可参考前述描述，此处不再赘述。
具体实现时，在所述LBT失败信息的复用优先级仅低于C-RNTI MAC CE的复用优先级的情况下，所述LBT失败信息的复用优先级低于C-RNTI MAC CE的复用优先级，但所述LBT失败信息的复用优先级可以高于“Configured Grant Confirmation MAC CE”的复用优先级，或，与“Configured Grant Confirmation MAC CE”的复用优先级的复用优先级。
在所述LBT失败信息的复用优先级仅高于第一逻辑信道数据的复用优先级的情况下，所述LBT失败信息的复用优先级高于第一逻辑信道数据的复用优先级，但所述LBT失败信息的复用优先级可以低于“PHR MAC CE”的复用优先级，或与“PHR MAC CE”的复用优先级相等。
可见，在本实施例中，所述LBT失败信息的复用优先级至少高于除UL-CCCH之外的逻辑信道的数据的复用优先级，从而可以采用更高的优先级的MAC CE传输，减少MAC CE传输的延时。
需要说明的是，本发明实施例中介绍的多种可选的实施方式，彼此可以相互结合实现，也可以单独实现，对此本发明实施例不作限定。
为方便理解，示例说明如下。
实施例一
终端在1个小区的BWP-1上发生LBT失败，终端变更其激活的BWP-1到BWP-2，并发起随机接入过程。终端上报LBT失败信息给网络侧设备，该LBT失败信息的内容包括：逻辑信道标识(如，逻辑信道编号49)。
如图3所示，MAC CE可以仅包括MAC子头，且LCID携带在MAC子头中。该MAC CE可以不携带任何额外的MAC CE内容和MAC SDU内容，从而能够节省信令。
网络侧设备接收到该逻辑信道标识后，可以知道终端在激活的BWP上发生了LBT失败，从而可以指示终端并更激活的BWP或小区，以变更终端的工作频点，进而终端可以在变更后的工作频点后进行LBT，从而可以提高终端进行上行发送的成功率。
额外的，该LBT失败信息的复用优先级至少高于除UL-CCCH之外的逻辑信道的数据。
更进一步的，该LBT失败信息的复用优先级可以为以下任意一种：
与C-RNTI MAC CE的复用优先级相同；
仅低于C-RNTI MAC CE的复用优先级；
仅高于除UL-CCCH之外的逻辑信道的数据的复用优先级。
实施例二
终端在1个小区的BWP-1发生LBT失败，终端变更其激活的BWP-1到BWP-2，并发起随机接入过程。终端上报LBT失败信息给网络侧设备，该LBT失败信息的内容包括：一个发生LBT失败的BWP标识(如，BWP编号1)。
如图4所示，MAC CE可以包括MAC子头和MAC内容，且LBT失败信息携带在MAC CE内容中。
其中，该BWP标识指示的BWP为以下任意一种：
首次发生LBT失败的BWP。比如，终端在BWP-1上发生LBT失败，变换到BWP-2，然后在BWP-2上发起随机接入过程，但是仍然发生LBT失败，变换到BWP-3。由于BWP-1为首次发生上行LBT失败的BWP，则终端在BWP-3上上报的LBT失败信息为BWP-1。
最近一次发生LBT失败的BWP。比如，终端在BWP-1上发生LBT失败，变换到BWP-2，然后在BWP-2上发起随机接入过程，但是仍然发生LBT失败，变换到BWP-3。由于BWP-2为最近一次发生LBT失败的BWP，则终端在BWP-3上上报的LBT失败信息为BWP-2。
额外的，该LBT失败信息的复用优先级至少高于除UL-CCCH之外的逻辑信道的数据。
更进一步的，该LBT失败信息的复用优先级可以为以下任意一种：
与C-RNTI MAC CE的复用优先级相同；
仅低于C-RNTI MAC CE的复用优先级；
仅高于除UL-CCCH之外的逻辑信道的数据的复用优先级。
实施例三
终端在1个小区的BWP-1发生LBT失败，终端变更其激活的BWP-1到BWP-2，并发起随机接入过程。终端上报LBT失败信息给网络侧设备，该LBT失败信息的内容包括：一个或多个发生LBT失败的BWP标识(如，BWP编号1、BWP编号2和BWP编号3)。
BWP标识后可以有额外的指示域指示是否还有额外的BWP标识。该指示域为E域，该指示域取值为“0”时，表示后续没有BWP标识，该指示域取值为“1”时，表示后续还有BWP标识。
如图5所示，MAC CE可以包括MAC子头和MAC内容，且LBT失败信息携带在MAC CE内容中。具体地，MAC CE内容中包括一个字节，该字节的第一个比特位和第二个比特位用于指示BWP标识1；第四个比特位和第五个比特位用于指示BWP标识2；的第七个比特位和第八个比特位用于指示BWP标识3；第三个比特位和第六个比特位均为E域，由于第三个比特位和第六个比特位的后续比特位都指示有BWP标识，因此，第三个比特位和第六个比特位的E域的取值为1。
额外的，该BWP标识的排列顺序可以按照发生LBT失败的先后顺序排列。比如，最先发生LBT失败的BWP的标识排列在最前，相应的，最后发生LBT失败的BWP的标识排列在最后；又比如，最后发生LBT失败的BWP的标识排列在最前，最先发生LBT失败的BWP标识排列在最后。
额外的，对于在BWP的标识之后设置的指示域指示没有后续的BWP标识时，则MAC CE内容中剩余比特位可以保留，可以称之为保留比特位。
额外的，该LBT失败信息的复用优先级至少高于除UL-CCCH之外的逻辑信道的数据。
更进一步的，该LBT失败信息的复用优先级可以为以下任意一种：
与C-RNTI MAC CE的复用优先级相同；
仅低于C-RNTI MAC CE的复用优先级；
仅高于除UL-CCCH之外的逻辑信道的数据的复用优先级。
需要说明的是，图3至图5中的MAC CE，其中，R表示其对应的比特位为保留比特位。另外，图3中LCID占用的比特数，图4和图5中BWP标识占用的比特数均为示例，本发明实施例并不因此限制比特数的占用数量。
本发明实施例可以包括：
第一格式的MAC CE，其只包含MAC subheader。
第二格式的MAC CE，其只包含MAC subheader+MAC CE内容，其中该MAC CE内容中包含发生失败的BWP的指示信息。
通过本发明实施例，当UE由于上行LBT失败触发BWP变更的时候，UE可以通过特定的MAC CE格式将上行LBT失败信息报告给网络侧，从而可以在上报信令的信令负荷和上报信息量间获得平衡。并通过采用更高的优先级的MAC CE传输，减少MAC CE传输的延时。
