非授权频谱是国家和地区划分的可用于无线电设备通信的频谱，该频谱通常被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，不需要向政府申请专有的频谱授权。例如，在一些地区，通信设备遵循“先听后说”原则，即通信设备在非授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在非授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。随着无线通信技术的发展，LTE系统和NR系统都会考虑在非授权频谱上布网，以利用非授权频谱来进行数据业务的传输。
即上行载波可以包括非授权频谱载波和授权频谱载波。
但是，在相关技术中，终端设备只支持通过授权频谱载波进行随机接入，导致随机接入性能过低。

需要说明的是，图1仅为示例性架构图，除图1中所示功能单元之外，该网络架构还可以包括其他功能单元或功能实体，本申请实施例对此不进行限定。
例如，图1所示通信网络为5G网络通信系统。
上述终端设备可以为用户设备(user equipment，UE)。例如，手机、电脑，还可以为蜂窝电话、无绳电话、会话发起协议(session initiation protocol，SIP)电话、智能电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、电脑、膝上型计算机、手持式通信设备、手持式计算设备、卫星无线设备、无线调制解调器卡、电视机顶盒(set top box，STB)、用户驻地设备(customer premise equipment，CPE)和/或用于在无线系统上进行通信的其它设备。

应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
在图1和图2所示的系统框架中，所述终端设备可以采用非授权频谱的载波或授权频谱的载波进行数据传输。非授权频谱是国家和地区划分的可用于无线电设备通信的频谱，该频谱通常被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，不需要向政府申请专有的频谱授权。例如，在一些地区，通信设备遵循“先听后说”原则，即通信设备在非授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在非授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。随着无线通信技术的发展，LTE系统和NR系统都会考虑在非授权频谱上布网，以利用非授权频谱来进行数据业务的传输。
图3至图5为本申请实施例的应用场景的示例。
在3GPP RAN#82次会议上，通过了新的工作项目“NR-based Access to Unlicensed Spectrum”，即在非授权频谱上使用NR技术进行接入，简称NR-U。在该工作项目中定义的部署场景包括独立布网(Standalone，SA)和非独立布网(Non Standalone，NSA)两大类，其中SA包括一种新的场景(Scenario)D，Scenario D是stand-alone的非授权载波的新无线(A stand-alone NR cell in unlicensed band and UL in licensed band，NR-U)，在这种场景下，如图3和图4所示，小区的下行载波是通过非授权频谱实现的，而上行载波可以同时通过非授权频谱和授权频谱实现，也可以只通过授权频谱实现。与Scenario D相似的场景还包括Scenario C，即Stand-alone NR-U，如图5所示，Scenario C下小区的下行载波和上行载波都是通过非授权频谱实现的。
此外，在图1和图2所示的系统中还可以引入了增补上行(Supplement Uplink，SUL)载波，以增强上行覆盖。所述SUL载波可以不单独对应一个小区，例如与非SUL的上行载波配对对应一个小区的上行载波。这与NR-U的Scenario D是类似的，即在非授权的频谱的基础上存在一个授权的上行载波，如SUL载波。如果网络配置了SUL载波，终端设备可以根据下行载波的测量结果选择在非SUL载波或SUL载波上发起随机接入，如考虑到SUL具有更好的覆盖，所述终端设备可以根据下行的RSRP结果决定在非SUL或SUL载波的PRACH资源发起接入过程。具体地，所述终端设备在检测到一个小区后，获得系统消息，如果系统消息中包含了SUL的配置，则所述终端设备可以根据下行的测量结果，如RSRP，选择非SUL或SUL载波的PRACH资源发起接入。
对于NR-U的SA部署的小区，网络在非授权频谱上发送初始接入相关的信息，包括同步信号、MIB和SIB等，对于所述终端设备来说，需要在接收同步信号、MIB和SIB之后，获得PRACH资源信息，从而在上行载波发送PRACH，完成初始接入过程。但是，在NR-U场景下，在Scenario C和Scenario D之间，下行都是通过非授权频谱的载波接收系统消息，而上行可能存在两种类型的频谱可以使用。也就是说，在NR-U部署下所述终端设备并不能有效区分Scenario C和Scenario D，即所述终端设备可以在使用授权频谱的载波上发起随机接入，也可以在使用非授权频谱的载波上发起随机接入，但所述终端并不知道在哪种类型的载波上发起随机接入。如果所述终端设备还是通过下行RSRP的测量结果确定发起随机接入的上行载波，会降低随机接入性能。
具体地，在NR-U场景下，上行载波包括使用非授权频谱的载波和使用授权频谱的载波，除了根据RSRP测量结果，还需要考虑非授权频谱的信道可获得性因素对上行随机接入的影响，这与NR场景下上行载波都是授权频谱的情况是不同的，如果通过下行RSRP的测量结果确定发起随机接入的上行载波，仅仅考虑了载波的覆盖率，而没有考虑非授权频谱的信道可获得性因素对上行随机接入的影响，因此会降低随机接入性能，尤其会造成NR-U的Scenario D的随机接入性能下降。
也就是说，终端设备的上行载波可以包括使用非授权频谱的载波和使用授权频谱的载波。但是，在相关技术中，终端设备只考虑了仅仅考虑了载波的覆盖率，而没有考虑非授权频谱的信道可获得性因素对上行随机接入的影响，因此会降低随机接入性能，尤其会造成NR-U的Scenario D的随机接入性能下降。
本申请实施例提供了一种无线通信的方法，所述终端设备能够在使用授权频谱的载波或使用非授权频谱的载波上发送目标上行信道，例如随机接入信道，由此，终端设备不仅可以考虑载波的覆盖率，而且还可以考虑非授权频谱的信道可获得性因素对上行随机接入的影响，因此能够提高随机接入性能，尤其能够提高NR-U的Scenario D的随机接入性能。

具体地，所述终端设备确定使用授权频谱的载波为目标上行载波，并在所述目标上行载波上发送目标上行信道；或者所述终端设备确定使用非授权频谱的载波为目标上行载波，并在所述目标上行载波上发送目标上行信道。在网络设备侧，所述网络设备可以确定使用授权频谱的载波为目标上行载波；所述网络设备在所述目标上行载波上接收终端设备发送的目标上行信道；或者所述网络设备可以确定使用非授权频谱的载波为目标上行载波；或者所述网络设备在所述目标上行载波上接收终端设备发送的目标上行信道。
所述目标上行信道可以包括以下信道中的至少一项：
物理随机接入信道(Physical Random Access Channel，PRACH)、物理上行控制信道(Physical Uplink Control channel，PUCCH)、物理上行共享信道(Physical Uplink Shared channel，PUSCH)调度请求(Scheduling Request，SR)以及上行参考信号等。其中上行参考信号可以包括上行解调参考信号(Demodulation Reference Signal，DMRS)、探测参考信号(Sounding Reference Signal，SRS)以及相位跟踪参考信号(PT-RS)等。其中，上行DMRS可用于上行信道的解调，SRS可用于上行信道的测量、上行时频同步或相位跟踪，PT-RS也可用于上行信道的测量、上行时频同步或相位跟踪。
应理解，本申请实施例中可以包括和上述名称相同、功能不同的上行物理信道或上行参考信号，也可以包括和上述名称不同、功能相同的上行物理信道或上行参考信号，本申请对此并不限定。
本申请实施例的方法，所述终端设备能够在使用授权频谱的载波或使用非授权频谱的载波上发送目标上行信道，例如随机接入信道，由此，终端设备不仅可以考虑载波的覆盖率，而且还可以考虑非授权频谱的信道可获得性因素对上行随机接入的影响，因此能够提高随机接入性能，尤其能够提高NR-U的Scenario D的随机接入性能。
本申请实施例中，所述终端设备确定所述目标载波时，可以基于使用授权频谱的载波的覆盖率和/或可获得性确定所述目标载波，也可以基于使用非授权频谱的载波的覆盖率和/或可获得性确定所述目标载波，也可以结合使用授权频谱的载波的覆盖率和/或可获得性和使用非授权频谱的载波的覆盖率和/或可获得性确定所述目标载波，能够有效提高所述目标上行信道的传输效率。例如，所述目标上行信道为物理随机接入信道时，能够提高随机接入性能，尤其能够提高NR-U的Scenario D的随机接入性能。
如图2所示，所述方法200还可以包括：
S230，网络设备确定使用授权频谱的载波或使用非授权频谱的载波为目标上行载波，以便接收终端设备在所述目标上行载波上发送的所述目标上行信道。
应理解，所述网络设备确定所述目标上行载波的实现方式和所述终端设备确定所述目标上行载波的实现方式类似，为了避免重复，下面以终端设备确定所述目标上行载波为例对本申请实施例的确定目标上行载波的实现方式进行详细说明：
实施例一：
可选地，所述终端设备根据第一规则确定所述目标上行载波。
所述第一规则包括使用授权频谱的载波的第一信道和/或使用非授权频谱的载波的第二信道，所述第一信道包括PRACH、PUCCH、SRS以及SR中的至少一项，所述第二信道包括PUSCH。例如，所述第一信道包括所述目标上行信道；所述终端设备确定使用授权频谱的载波为所述目标上行载波。
由此，所述终端设备可以根据所述目标上行信道的类型和所述第一规则，确定用于发送所述目标上行信道的载波类型。例如，假设所述目标上行信道为PRACH，则所述终端设备根据所述第一规则确定出PRACH所使用的载波类型为使用授权频谱的载波，则所述终端设备可以将使用授权频谱的载波确定为所述目标上行载波，进而在所述目标上行载波上发送PRACH。
由于授权载波上的上行发送不需要进行LBT，因此对于一些重要的或者时延敏感的信息，可以规定通过授权载波进行发送，例如PRACH、PUCCH、SRS、SR等。对于数据的发送，如PUSCH，可以通过非授权载波或授权载波发送，即通过授权频谱发送PRACH，可以保证PRACH在预定的时频资源上及时发送，而不存在LBT失败造成的无法发送的情况，保证了PRACH发送的可靠性和及时性，减少PRACH发送的延时。
应理解，所述第一信道和所述第二信道包括的信道类型仅为本申请的一种示例，不应理解为对本申请实施例的限制。例如，在其他可替代实施例中，所述第一信道还可以包括DMRS和/或PT-RS等。
可选地，所述方法200还可以包括：
所述终端设备接收第一指示信息，所述第一指示信息用于指示所述终端设备的上行载波包括使用授权频谱的载波和使用非授权频谱的载波。

可选地，所述终端设备接收系统信息，所述系统信息包括所述第一指示信息。
以所述目标上行信道为PRACH为例，假设上行载波包括使用授权频谱的载波和使用非授权频谱的载波，当网络设备通过所述第一指示信息指示所述终端设备的上行载波包括使用授权频谱的载波和使用非授权频谱的载波时，所述终端设备根据所述第一规则确定所述目标上行载波后，所述终端设备可以使用所述目标上行载波上的系统消息包括的PRACH资源配置信息发起随机接入。所述系统消息中的PRACH资源配置信息可以不包含载波信息，也可以包括载波信息，本申请实施例对此不做具体限定。
例如，PRACH资源配置信息可以沿用现有的随机接入信道配置方式，即PRACH资源配置信息可以为公共无线资源配置信息(RACH-ConfigCommon)。
又例如，所述目标上行信道的资源配置信息可以包括使用非授权频谱上的载波的资源配置信息和使用授权频谱的载波上的资源配置信息。当使用非授权频谱上的载波的资源配置信息和使用授权频谱的载波上的资源配置信息相同时，所述网络设备只需要配置一个资源配置信息，由此不管终端设备使用哪种载波，都可以结合所述一个资源配置信息发送所述目标上行信道。所述资源配置信息可以包括时域资源的配置信息和/或频域资源的配置信息。使用非授权频谱上的载波的时域资源的配置信息可以和使用授权频谱的载波上的时域资源的配置信息相同或不相同，本申请实施例对此不做具体限定。
实施例二：
可选地，所述终端设备接收第二指示信息；所述终端设备根据所述第二指示信息在所述使用授权频谱的载波和所述使用非授权频谱的载波中确定所述目标上行载波，所述第二指示信息用于指示所述目标上行载波为使用授权频谱的载波或者为使用非授权频谱的载波。
所述网络设备生成并向所述终端设备发送所述第二指示信息。
由此，所述终端设备可以将所述第二指示信息指示的载波类型确定为所述目标上行载波。
可选地，所述终端设备接收所述网络设备发送的系统信息，所述系统信息包括所述第二指示信息。
假设下行载波为使用非授权频谱的载波，上行载波包括使用授权频谱的载波和使用非授权频谱的载波，在下行载波上，所述网络设备可以通过在系统信息中携带所述第二指示信息，用于指示所述终端设备应该在使用授权频谱的载波还是在使用非授权频谱的载波上发送所述目标上行信道。
下面对网络设备通过所述系统信息指示所述目标上行载波为使用授权频谱的载波或者为使用非授权频谱的载波的具体实现方式进行说明。
可选地，所述系统消息为主信息块MIB。
在一种实施例中，所述第二指示信息通过所述MIB的占用比特中的空闲比特指示所述目标上行载波为使用授权频谱的载波或者为使用非授权频谱的载波。
以所述系统信息承载在PBCH上为例，PBCH承载的信息可以包括来自高层的A比特信息和与层1相关的额外8比特信息，层1信息包括SFN、半帧指示、SSB index等。具体地，PBCH承载的信息包括来自高层的MIB，共A比特，

和层1信息的占用比特8比特，
Figure PCTCN2019072248-appb-000002
其中A比特MIB包括SFN的6比特，子载波间隔信息1比特，SSB的子载波偏移4比特，DMRS相关信息、调度SIB的PDCCH的资源信息等，其中还包含了1个空闲比特。本申请实施例中，可以通过所述1个空闲比特携带所述第二指示信息。例如，所述1个空闲比特为1时用于指示所述目标上行载波为使用授权频谱的载波，所述1个空闲比特为0时用于指示所述目标上行载波为使用非授权频谱的载波。
在另一种实施例中，所述第二指示信息通过所述MIB的层1信息的占用比特中的保留比特指示所述目标上行载波为使用授权频谱的载波或者为使用非授权频谱的载波。
以所述系统信息承载在PBCH上为例，PBCH承载的信息可以包括来自高层的A比特信息和层1相关的额外8比特信息，层1相关的信息包括SFN、半帧指示、SSB index等。具体地，层1的8比特，
Figure PCTCN2019072248-appb-000003
中，
Figure PCTCN2019072248-appb-000004
为SFN的最低4位；
Figure PCTCN2019072248-appb-000005
为半帧指示；当L SSB＝64时，
Figure PCTCN2019072248-appb-000006
为SSB index的最高3位，否则，
Figure PCTCN2019072248-appb-000007
为参数k SSB的最高位，
Figure PCTCN2019072248-appb-000008
为保留比特。其中，L SSB为最大的SSB个数，k SSB为SSB的子载波偏移信息。当系统频带小于6GHz时，即L SSB小于64时，层1相关的信息有2个保留比特，本申请实施例中，可以使用所述2个保留比特中任一预留 比特携带所述第二指示信息。例如，所述1个空闲比特为1时用于指示所述目标上行载波为使用授权频谱的载波，所述1个空闲比特为0时用于指示所述目标上行载波为使用非授权频谱的载波。
可选地，所述系统消息为系统信息块SIB。
在一种实施例中，所述SIB包括所述目标上行信道的配置信息，所述配置信息包括所述第二指示信息。
以所述目标上行信道为PRACH为例，PRACH资源配置信息可以沿用现有的随机接入信道配置方式，即所述SIB可以包括公共无线资源配置信息(RACH-ConfigCommon)。本申请实施例中，可以在公共无线资源配置信息中添加所述第二指示信息，用于指示用于发送PRACH的载波信息，例如对该公共无线资源配置信息增加PRACH载波信息(prach-ULunlicensed)，用于指示用于发送PRACH的载波为使用授权频谱的载波或者为使用非授权频谱的载波。例如，当PRACH载波信息为1时用于指示在非授权频谱的载波上发送PRACH，当PRACH载波信息为0时用于指示在授权频谱的载波上发送PRACH。
本申请实施例中，通过所述第二指示信息确定用于发送所述目标上行信道的目标上行载波，有利于网络灵活的控制所述目标上行载波的类型，从而可以对两种类型的载波的资源负荷进行有效的均衡。当非授权频谱的载波的信道比较繁忙时，例如先听后说(Listen Before Talk，LBT)成功的概率较低，可以通过指示终端设备在授权频谱的载波上发送所述目标上行信道，从而保证所述目标上行信道发送成功的概率。而当非授权载波的信道比较空闲时，例如LBT成功的概率较高，可以通过指示所述终端设备在非授权频谱的载波上发送所述目标上行信道，从而充分利用非授权频谱，增加上行吞吐量。
实施例三：
可选地，所述终端设备确定使用非授权频谱的载波为所述目标上行载波。
换句话说，假设上行载波包括使用授权频谱的载波和使用非授权频谱的载波，则所述终端设备优先确定使用非授权频谱的载波为所述目标上行载波。
进一步地，所述终端设备根据所述目标上行载波的信道接入情况，在所述目标上行载波上发送所述目标上行信道。例如，所述终端设备针对所述目标上行载波进行先听后说LBT成功时，在所述目标上行载波上发送所述目标上行信道。
更进一步地，所述方法200还可以包括：
所述终端设备针对所述目标上行载波进行先听后说LBT失败次数大于等于第一阈值时，重新确定使用授权频谱的载波为所述目标上行载波；所述终端设备在重新确定的所述目标上行载波上发送所述目标上行信道。其中，所述第一阈值为预配置阈值，或者，所述第一阈值为网络设备配置的阈值。例如，可以通过系统消息将所述第一阈值指示给所述终端设备。
或者说，所述终端设备针对所述目标上行载波进行先听后说LBT失败次数大于等于第一阈值时，切换到使用授权频谱的载波上发送所述目标上行信道。
具体地，所述终端设备先获得使用非授权频谱的载波上的用于发送所述目标上行信道的资源配置信息，当所述终端设备需要发送所述目标上行信道时，所述终端设备优先在使用非授权频谱的载波上的资源上发送所述目标上行信道，由于是非授权频谱，所述终端设备在发送所述目标上行信道之前，需要针对所述目标上行载波进行LBT，所述终端设备可以根据LBT的结果重新确定用于发送所述目标上行信道的目标载波。例如，所述终端设备在使用非授权频谱的载波上在发送所述目标上行信道之前，进行的LBT失败之后，在下一个使用授权频谱的载波的发送时机，切换到使用授权频谱的载波上发送所述目标上行信道。
图7是本申请实施例的无线通信方法的示意性流程图。
下面以所述目标上行信道为PRACH为例对本申请实施例的无线通信的方法进行说明。
如图7所示，所述方法300可以包括：
S310，终端设备获取使用授权频谱的载波和使用非授权频谱的载波上的PRACH的配置信息。
S320，所述终端设备在使用非授权频谱的载波上的PRACH发送时机之前进行LBT。
S330，所述终端设备确定LBT是否失败。
S340，若LBT没有失败，则所述终端设备在使用非授权频谱的载波上发送PRACH。
S350，若LBT失败，确定LBT失败次数是否大于或等于数值N，其中数值N可以是预配置数值或者网络设备配置的数值。
S360，若LBT失败次数>N，则所述终端设备在使用授权频谱的载波上发送PRACH。
可选地，所述方法200还可以包括：
所述终端设备在重新确定的所述目标载波上发送所述目标上行信道成功后，确定使用非授权频谱 的载波为用于下次发送所述目标上行信道的目标上行载波。
即所述终端设备在使用授权频谱的载波上发送所述目标上行信道成功后，确定使用非授权频谱的载波为用于下次发送所述目标上行信道的目标上行载波。以所述目标上行信道为PRACH为例，所述终端设备在使用授权频谱的载波上发送PRACH成功后，在下一次随机接入过程中，所述终端设备仍然优先确定使用非授权频谱的载波为用于发送PRACH的目标上行载波。
本申请实施例中，所述终端设备可以根据信道接入的情况，动态的调整用于发送所述目标上行信道的目标上行载波，从而充分利用非授权频谱的载波发送目标上行信道的同时，避免了在非授权载波上长时间无法获得信道占用而增大目标上行信道的发送延时。
实施例四：
可选地，所述终端设备根据使用非授权频谱的载波的信道测量结果确定所述目标上行载波。
假设上行载波包括使用授权频谱的载波和使用非授权频谱的载波，所述终端设备需要发送所述目标上行信道时，进行信道占用情况的测量，例如，用于体现信道占用情况的测量量为信号强度指示(Received Signal Strength Indication，RSSI)。
例如，所述终端设备通过比较使用非授权频谱的载波的RSSI和第二阈值，确定所述目标上行载波。所述第二阈值为预配置阈值，或者所述第二阈值为网络设备配置的阈值。
例如，使用非授权频谱的载波的RSSI小于第二阈值时，所述终端设备确定非授权频谱的载波为所述目标载波；和/或使用非授权频谱的载波的RSSI大于或等于所述第二阈值时，所述终端设备确定使用授权频谱的载波为所述目标载波。又例如，使用非授权频谱的载波的RSSI小于或等于第二阈值时，所述终端设备确定非授权频谱的载波为所述目标载波；和/或使用非授权频谱的载波的RSSI大于所述第二阈值时，所述终端设备确定使用授权频谱的载波为所述目标载波。

S450，若使用非授权频谱的载波的RSSI大于或等于数值T，则所述终端设备在使用授权频谱的载波上发送PRACH。
本申请实施例中，所述终端设备可以根据使用非授权频谱的载波的测量结果，判断载波的信道占用情况或状况，进而动态的调整用于发送所述目标上行信道的目标上行载波，从而充分利用非授权频谱的载波发送目标上行信道的同时，避免了在非授权载波上长时间无法获得信道占用而增大目标上行信道的发送延时。信道占用情况或状况可以用信道占用比例或时间等参数表示。指例如，通过测量RSSI，可以有效评估使用非授权频谱的载波的信道状态，以及估计在使用非授权频谱的载波上获得信道占用的难易程度或者LBT失败的概率，从而确定是否在非授权载波上发送所述目标上行信道。

应理解，本实施例可以和实施例四结合也可以不结合，本申请实施例对此不做具体限定。
图9是本申请实施例的无线通信方法的示意性流程图。
下面以所述目标上行信道为PRACH为例对本申请实施例的无线通信的方法进行说明。
S510，终端设备获取使用授权频谱的载波和使用非授权频谱的载波上的PRACH的配置信息。
S520，所述终端设备测量使用非授权频谱的载波的RSSI，测量使用非授权频谱的载波或者使用授权频谱的载波的RSRP。
S530，所述终端设备判断RSSI满足门限1且RSRP满足门限2。
S540，若所述终端设备判断RSSI不满足门限1和/或RSRP不满足门限2，则所述终端设备在使用授权频谱的载波上发送PRACH。所述门限1和所述门限2可以是预配置门限，也可以是网络设备配置的门限。
S550，若所述终端设备判断RSSI满足门限1且RSRP满足门限2，则所述终端设备在使用非授权频谱的载波上发送PRACH。
本申请实施例中，终端设备根据非授权载波的RSSI测量结果和下行非授权频谱载波的RSRP测量结果，综合考虑选择的目标上行载波，即终端设备同时考虑了非授权频谱载波的信道状态和小区的覆盖情况，进而确定用于发送目标上行信道的目标上行载波。换句话说，所述终端设备可以根据表征使用非授权频谱的载波的信道状态的测量结果以及表征覆盖的测量结果，共同确定所述目标上行载波，从而可以选择最合理的上行载波，充分利用了非授权频谱的载波，又避免了由于非授权载波的覆盖差而造成的所述目标上行信道发送失败，提高了所述目标上行信道发送成功的概率。
可选地，所述方法200还可以包括：
所述终端设备获取所述使用授权频谱的载波的目标上行信道的配置信息和所述使用非授权频谱的载波的目标上行信道的配置信息。
例如，所述终端设备在发送所述目标上行信道之前，获取所述使用授权频谱的载波上的目标上行信道的配置信息和所述使用非授权频谱的载波上的目标上行信道的配置信息。
以上结合附图详细描述了本申请的优选实施方式，但是，本申请并不限于上述实施方式中的具体细节，在本申请的技术构思范围内，可以对本申请的技术方案进行多种简单变型，这些简单变型均属于本申请的保护范围。
例如，在实施例四或实施例五中，RSSI和RSRP仅为本申请的一种示例，不应理解为对本申请实施例的限定。换句话说，实施例四或实施例五中涉及的测量结果可以是表征使用非授权频谱的载波的信道状态和表征覆盖的任意测量结果。
还应理解，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合，为了避免不必要的重复，本申请对各种可能的组合方式不再另行说明。
还应理解，本申请的各种不同的实施方式之间也可以进行任意组合，只要其不违背本申请的思想，其同样应当视为本申请所公开的内容。
举例来说，实施例三可以进一步与实施例四或实施例五结合，例如，在根据实施例四或实施例五的方法确定采用非授权频谱的载波发送目标上行信道之后，如果LBT失败超过一定次数，则仍需要切换到授权频谱的载波发送目标上行信道。
应理解，在本申请的各种方法实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
上文中结合图1至图9，详细描述了本申请的方法实施例，下文结合图10至图13，详细描述本申请的装置实施例。
