在本实施例中，终端设备可以在一个载波的两个或两个以上的带宽单元进行信道检测，确定各带宽单元是否忙碌或空闲，从而可以更快地开始或完成数据传输。
在本实施例中，上述两个或两个以上带宽单元在上述载波的一个BWP上，该BWP可以是激活的BWP。
图3a-图3c是带宽单元与载波(carrier)的关系的示意图。如图3a所示，在这个示例中，一个上行载波(UL carrie)包括两个带宽单元，即带宽单元1和带宽单元2，并且这两个带宽单元在一个UL BWP上，该UL BWP是激活的BWP，这两个带宽单 元在频域上不重叠。如图3b所示，在这个示例中，一个上行载波(UL carrie)包括两个带宽单元，即带宽单元1和带宽单元2，并且这两个带宽单元在一个UL BWP上，该UL BWP是激活的BWP，这两个带宽单元在频域上有部分重叠。如图3c所示，在这个示例中，一个上行载波(UL carrie)包括三个带宽单元，即带宽单元1-3，并且这三个带宽单元在一个UL BWP上，该UL BWP是激活的BWP，并且，带宽单元1和带宽单元2在频域上不重叠，而带宽单元3与带宽单元1和2分别重叠。图3a-图3c的对应关系只是举例说明，本实施例不限于此。
在一个实施方式中，终端设备可以接收网络设备的指示以获知可用于上行传输的资源，例如，终端设备可以接收网络设备发送的至少一个指示信息(称为第一指示信息)，该至少一个第一指示信息指示了能够用于上行传输的至少一个资源。该一个资源是CG的资源或UL Grant的资源。
在本实施方式中，一个资源是指用于或对应一个完整上行传输的时频资源，这里的完整上行传输是指网络设备能够正常接收数据或者检测信号。
例如，如果一个资源用于发送物理随机接入信道(PRACH)或信号，则该一个资源是指对应一个随机接入信道机会(RACH occasion，RO)的时频资源，也即，该时频资源能够发送一个完整的preamble或者随机接入请求，网络设备能根据该preamble或随机接入请求发送与其对应的下行信号和/或信道，例如PDCCH，PDSCH等；如果一个资源用于发送物理上行共享信道(PUSCH)或信号，则该一个资源是指对应一个传输块(TB)的时频资源；如果一个资源用于发送物理上行控制信道(PUCCH)或信号，则该一个资源是指对应一个上行控制信息(UCI)的时频资源；如果一个资源用于发送探测参考信号(SRS)，则该一个资源是指对应一个SRS序列的时频资源。
在本实施方式中，上述至少一个第一指示信息可以是一个，也可以是多个。例如，当上述至少一个资源为两个或两个以上时，这两个或两个以上的资源可以用于发送相同的信号和/或信道，例如，都用于发送PRACH，或者都用于发送PUSCH等，此时，上述两个或两个以上的资源可以由同一个第一指示信息来指示，例如由同一个物理层信令指示。
在本实施方式中，该至少一个资源在频域上可以对应上述载波的两个或两个以上带宽单元中的至少一个带宽单元。例如，该至少一个资源在频域上对应的至少一个带 宽单元是两个或两个以上的带宽单元，该至少一个资源可以是两个或两个以上的资源，并且，该至少一个资源的时域起始位置是相同的。
再例如，该至少一个资源在频域上对应的至少一个带宽单元是两个或两个以上带宽单元，该至少一个资源是一个资源，该一个资源的对应不同带宽单元的各部分资源的时域起始位置相同。
图4a-图4b是资源与带宽单元之间的对应关系的示意图。如图4a所示，在这个示例中，两个资源在频域上分别对应一个带宽单元，并且这两个资源的时域起始位置相同。如图4b中，在这个示例中，一个资源的两部分分别对应一个带宽单元，并且，该资源的这两部分的时域起始位置相同。图4a和图4b只是举例说明，本实施例对此不作限制，例如也可以是一个资源如图4a的资源1或资源2所示对应一个带宽单元，而另一个资源如图4b的资源1所示，其两部分或多部分分别对应一个带宽单元。
在本实施例中，在步骤201中，终端设备可以根据网络设备的指示确定各带宽单元的信道检测方式，也可以根据自身能力决定各带宽单元的信道检测方式，本实施例对此不作限制。
在本实施例中，各带宽单元可以对应以下两种信道检测方式：固定时间长度的信道检测，基于随机退避机制的信道检测。
例如，各带宽单元可以都对应固定时间长度的信道检测方式，终端设备在上述两个或两个以上带宽单元上进行基于固定时间长度的信道检测。
再例如，其中一个带宽单元对应基于随机退避机制的信道检测方式，而其他带宽单元对应固定时间长度的信道检测方式，终端设备在上述两个或两个以上带宽单元的其中一个带宽单元上进行基于随机退避机制的信道检测，在上述两个或两个以上带宽单元的其他带宽单元上进行基于固定时间长度的信道检测。
在本实施例中，关于固定时间长度的信道检测和基于随机退避机制的信道检测的具体实现方式可以参考现有技术，此处省略说明。
在本实施例中，在步骤202中，终端设备可以根据以下至少一项发送上行传输：上述两个或两个以上带宽单元中被检测为空闲的带宽单元的数量；上述两个或两个以上带宽单元中被检测为空闲的带宽单元的位置；上述两个或两个以上带宽单元中被检测为空闲的带宽单元是否满足一定条件；以及上述上行传输包括的信号和/或信道。
在步骤202的一个实施方式中，终端设备可以根据前述至少一项判断是否发送上 行传输，在判断为是的情况下发送上行传输。
在本实施方式中，终端设备还可以接收网络设备发送的指示信息(称为第二指示信息)，该第二指示信息与该终端设备如何根据前述至少一项判断是否发送上行传输相关，也即，终端设备可以参考该第二指示信息并根据前述至少一项判断是否发送上行传输。
在本实施方式中，以终端设备根据上述两个或两个以上带宽单元中被检测为空闲的带宽单元的数量和/位置判断是否发送上行传输为例。
在这个例子中，网络设备可以通过上述第二指示信息指示终端设备如何根据该被检测为空闲的带宽单元的数量和/或位置判断是否发送上行传输，终端设备根据该第二指示信息的指示进行相应处理。
例如，第二指示信息指示可以在全部带宽单元(上述一个载波的两个或两个以上带宽单元)空闲的情况下发送上行传输，则终端设备判断是否全部带宽单元都被检测为空闲，如果判断为是，则发送上行传输。例如，假设共有N个带宽单元，其中M个带宽单元被检测为空闲，终端设备可以在N＝M时发送上行传输。
再例如，第二指示信息指示可以在部分带宽单元空闲，并且空闲的带宽单元中有至少两个连续的情况下发送上行传输，则终端设备判断空闲的带宽单元中是否有至少两个连续，如果判断为是，则发送上行传输。例如，假设共有N个带宽单元，其中M个带宽单元被检测为空闲，终端设备可以在N＞M，M≥1，并且M≥2时连续的情况下发送上行传输，此时，N和M有可能相等，N＝M，在这种情况下终端设备也可以发送上行传输。
再例如，第二指示信息指示可以在部分带宽单元空闲的情况下发送上行传输，则终端设备判断是否有空闲的带宽单元，如果判断为是，则发送上行传输。例如，假设共有N个带宽单元，其中M个带宽单元被检测为空闲，终端设备可以在N＞M，M≥2且不连续的情况下发送上行传输，此时，N和M有可能相等，即N＝M，或者，N和M有可能满足下列关系，即：N＞M，M≥1，并且M≥2时连续，在这两种情况下终端设备也可以发送上行传输。
在这个例子中，网络设备还可以针对不同的信号/信道给出不同的指示，例如，如果信号/信道的优先级较高，例如为PRACH，则网络设备可以通过上述第二指示信息指示在部分单元空闲的情况下发送上行传输，具体将在后面进行说明。
在本实施方式中，以终端设备根据上述两个或两个以上带宽单元中被检测为空闲的带宽单元是否满足一定条件判断是否发送上行传输为例。
例如，终端设备可以在被检测为空闲的带宽单元包括特定的带宽单元(称为第一带宽单元)时发送上行传输，也即终端设备判断被检测为空闲的带宽单元中是否包括上述第一带宽单元，如果判断为是，则发送上行传输。仍以前述为例，如果信道检测结果为部分空闲，N＞M，M≥1，则当该空闲的M个带宽单元中包括X(X≥1)个第一带宽单元时才发送上行传输。
在这个例子中，上述第一带宽单元可以是终端设备在进行前述信道检测之前自主选择的，也可以是网络设备通过前述第二指示信息直接或间接指示的。
例如，终端设备可以自主选择第一带宽单元。由此，当检测为空闲的带宽单元包含该随机选择的第一带宽单元时，终端设备发送上行传输。
再例如，前述第二指示信息可以直接指示该第一带宽单元，或者，前述第二指示信息可以指示网络设备如何选择该第一带宽单元，相当于间接指示了第一带宽单元。例如，该第一带宽单元为初始上行或下行BWP对应的带宽单元，网络设备可以通过前述第二指示信息指示该初始上行或下行BWP来间接指示该第一带宽单元。再例如，该第一带宽单元为上述至少一个资源对应的第1个带宽单元，则网络设备可以通过前述第二指示信息指示上述至少一个资源的位置来间接指示该第一带宽单元。上述第1个带宽单元例如为频域由低到高排列的带宽单元中的第1个，包含了上述至少一个资源仅对应一个带宽单元的情况。
在这个例子中，上述第一带宽单元可以是上述一个载波的两个或两个以上带宽单元中对应基于随机退避(random back-off)的信道检测的带宽单元。并且，该一个载波的两个或两个以上带宽单元中可以仅有一个带宽单元对应基于随机退避(random back-off)的信道检测。也即，如果上述一个载波的两个或两个以上带宽单元中仅包括一个对应基于随机退避的信道检测的带宽单元，第一带宽单元可以等同于该对应基于随机退避的信道检测的带宽单元，则终端设备可以自主选择该基于随机退避的信道检测的带宽单元，并在空闲的带宽单元包含该基于随机退避的信道检测的带宽单元时发送上行传输，或者，网络设备可以通过前述第二指示信息直接或间接指示该基于随机退避的信道检测的带宽单元，终端设备在空闲的带宽单元包含该基于随机退避的信道检测的带宽单元时发送上行传输。
在这个例子中，上述间接指示例如指示了两个或两个以上带宽单元中对应固定时间长度的带宽单元，则终端设备在其他的带宽单元中选择基于随机退避的带宽单元。固定时间长度是指不基于随机退避，不同情况下对应的长度可能不同。
在本实施方式中，以终端设备根据上述上行传输包括的信号和/或信道判断是否发送上行传输为例。
例如，上述信号和/或信道与在什么情况下发送上行传输可以具有对应关系，例如第一类信号可以在部分带宽单元空闲的情况下发送，则终端设备可以根据上行传输所包括的信号和/或信道决定是否发送上行传输。例如，PRACH可以在部分带宽单元空闲的情况下发送，则当上行传输为PRACH时，一旦检测到空闲的带宽单元，终端设备即发送该上行传输。以上只是举例说明，本实施例不限于此。
以上通过几个例子对步骤202中终端设备如何根据前述至少一项判断是否发送上行传输做了说明，上述例子可以任意组合，此处不再赘述。
在步骤202的另一个实施方式中，终端设备可以根据前述至少一项从被检测为空闲的带宽单元中选择上述至少一个带宽单元，并在选择的该至少一个带宽单元上发送上行传输。
在本实施方式中，终端设备还可以接收网络设备发送的指示信息(称为第三指示信息)，该第三指示信息与该终端设备如何从被检测为空闲的带宽单元上选择上述至少一个带宽单元相关，也即，终端设备可以参考该第三指示信息并根据前述至少一项从被检测为空闲的带宽单元中选择上述至少一个带宽单元。
在本实施方式中，终端设备可以根据前述至少一项从被检测为空闲的带宽单元中自主选择上述至少一个带宽单元，和/或终端设备也可以根据前述至少一项和/或网络设备的指示(例如前述第三指示信息)从被检测为空闲的带宽单元中选择上述至少一个带宽单元。
例如，第三指示信息指示了“随机选择”，则终端设备可以根据该第三指示信息在被检测为空闲的带宽单元中随机选择上述至少一个带宽单元。
再例如，第三指示信息指示了“基于特定带宽单元进行选择”，则终端设备可以根据该第三指示信息在被检测为空闲的带宽单元中选择包含该特定的带宽单元(称为第二带宽单元)的上述至少一个带宽单元。
再例如，第三指示信息指示了“基于分组和/或排序进行选择”，则终端设备可以 根据该第三指示信息对被检测为空闲的带宽单元或进行信道检测的上述一个载波的两个或两个以上带宽单元进行分组和/或排序，并按照该分组和/或顺序选择上述至少一个带宽单元。或者，第三指示信息指示了上述一个载波的两个或两个以上带宽单元的分组和/或排序，则终端设备可以按照该分组和/或顺序选择上述至少一个带宽单元。
在本实施方式中，上述第二带宽单元的定义与前述第一带宽单元的定义类似，并且，该第二带宽单元可以与前述第一带宽单元相同，也可以不相同。在本实施方式中，该第二带宽单元可以是终端设备自主选择的，也可以是网络设备指示的，例如通过前述第三指示信息指示，指示的方式与通过第二指示信息指示第一带宽单元的方式类似，例如，该第三指示信息可以直接指示该第二带宽单元，或者，该第三指示信息可以指示终端设备如何选择该第二带宽单元，相当于间接指示了第二带宽单元。例如，该第二带宽单元为初始上行或下行BWP对应的带宽单元，网络设备可以通过前述第三指示信息指示该初始上行或下行BWP来间接指示该第二带宽单元。再例如，该第二带宽单元为上述至少一个资源对应的第1个带宽单元，则网络设备可以通过前述第三指示信息指示上述至少一个资源的位置来间接指示该第二带宽单元。上述第1个带宽单元例如为频域由低到高排列的带宽单元中的第1个，包含了上述至少一个资源仅对应一个带宽单元的情况。
在这个例子中，上述第二带宽单元可以是上述一个载波的两个或两个以上带宽单元中对应基于随机退避(random back-off)的信道检测的带宽单元。并且，该一个载波的两个或两个以上带宽单元中可以仅有一个带宽单元对应基于随机退避(random back-off)的信道检测。也即，如果上述一个载波的两个或两个以上带宽单元中仅包括一个对应基于随机退避的信道检测的带宽单元，第二带宽单元可以等同于该对应基于随机退避的信道检测的带宽单元，则终端设备可以自主选择该基于随机退避的信道检测的带宽单元，并在空闲的带宽单元包含该基于随机退避的信道检测的带宽单元时发送上行传输，或者，网络设备可以通过前述第三指示信息直接或间接指示该基于随机退避的信道检测的带宽单元，终端设备在空闲的带宽单元包含该基于随机退避的信道检测的带宽单元时发送上行传输。
在这个例子中，上述间接指示例如指示了两个或两个以上带宽单元中对应固定时间长度的带宽单元，则终端设备在其他的带宽单元中选择基于随机退避的带宽单元。固定时间长度是指不基于随机退避，不同情况下对应的长度可能不同。
在本实施方式中，当该第二带宽单元与前述第一带宽单元相同时，第三指示信息和前述第二指示信息可以是同一个。
在本实施方式中，上述的至少一个带宽单元即为前述例子中的M个带宽单元，其可以仅包括一个带宽单元，也即M＝1；或者，其也可以包括两个或两个以上带宽单元并且在频域上连续或不连续，也即M≥2且连续或不连续。
图5a-图5d是选择带宽单元的示意图。如图5a所示，在这个示例中，终端设备在上行载波对应的两个带宽单元上进行信道检测，这两个带宽单元在UL BWP上，检测结果为带宽单元1是空闲的，而带宽单元2是忙碌的，则终端设备可以选择在带宽单元1上进行上行传输(PRACH)。如图5b所示，在这个示例中，与图5a的示例不同的是，检测结果为两个带宽单元都是空闲的，终端设备可以选择其中一个，例如带宽单元1进行上行传输(PRACH)。如图5c所示，在这个示例中，终端设备在上行载波对应的四个带宽单元上进行上行传输，这四个带宽单元在UL BWP上，检测结果为带宽单元1-2,4是空闲的，而带宽单元3是忙碌的，则终端设备可以选择带宽单元1和带宽单元2发送上行传输(PUSCH)。如图5d所示，在这个示例中，与图5c的示例不同的是，只有带宽单元2和带宽单元3分别对应一个资源，则尽管带宽单元1和带宽单元2都是空闲的，但是终端设备选择带宽单元2进行上行传输(PRACH)。
需要指出的是，在图5d中，终端设备在UL BWP或UL carrier中的全部带宽单元1-4进行信道检测，但本发明不限于此，终端设备也可以仅在资源对应的带宽单元上进行信道检测，例如仅在资源1-2对应的带宽单元2-3上进行信道检测。
在步骤202的再一个实施方式中，终端设备还可以根据前述至少一项在发送上行传输之前切换发送带宽或者不切换发送带宽。例如，终端设备可以根据前述至少一项和/或网络设备的指示和/或终端设备的能力，判断是否切换发送带宽，如果判断为是，则终端设备在发送上行传输之前切换发送带宽。
在本实施方式中，终端设备可以接收网络设备发送的指示信息(称为第四指示信息)，该第四指示信息与终端设备在发送上行传输之前是否切换发送带宽相关，也即，终端设备可以参考该第四指示信息并根据前述至少一项和/或终端设备的能力在发送上行传输之前切换发送带宽或者不切换发送带宽。
在本实施方式中，假设发送上行传输的带宽单元为K个，K≥1，如果允许终端 设备在一部分带宽单元K’(K’＞K)上发送上行传输，则网络设备可以通过上述第四指示信息指示终端设备是否需要在发送上行传输之前切换发送带宽。
例如，网络设备可以根据信道拥挤程度通过上述第四指示信息指示终端设备是否需要在发送上行传输之前切换发送带宽。当信道拥挤时，可指示终端设备在发送上行传输之前切换发送带宽，以降低终端设备的上行传输对其他设备的影响；否则，可指示终端设备在发送上行传输之前不切换发送带宽。
再例如，终端设备可以根据上行传输所包含的信号和/或信道判断是否需要切换发送带宽。例如，如果上行传输所包含的信号和/或信道为PRACH，则不切换发送带宽，否则切换发送带宽，以降低对其他设备的影响。
在这个例子中，以PRACH为例做了说明，本实施例对此不作限制，在具体实施过程中，是否切换发送带宽与上行传输所包含的信号和/或信道有对应关系，例如，第一类信号和/或信道对应切换发送带宽，第二类信号和/或信道对应不切换发送带宽，由此，终端设备可以根据上行传输所包括的信号和/或信道来决定是否切换发送带宽。
前述以三个实施方式为例对终端设备如何根据前述至少一项发送上行传输进行了说明，在具体实施过程中，上述三个实施方式可以任意组合，例如，终端设备可以仅判断是否发送上行传输而不选择上述至少一个带宽单元也不切换发送带宽，或者，终端设备可以既判断是否发送上行传输也选择上述至少一个带宽单元，但不切换发送带宽，等等，此处不再赘述。
在本实施例中，上述指示信息(第一指示信息～第四指示信息)可以是以下信息或信令的至少一种：物理层信令、媒体接入控制(MAC)层信令，无线资源控制(RRC)信令。
在本实施例中，考虑终端设备的硬件成本，小区或系统中可能既包括支持该能力的终端设备，也包括不支持该能力的终端设备。此时，为了实现终端设备之间或者不同系统间更好的共存(协调资源)，终端设备可以向网络设备告知(上报)与该能力相关的信息。网络设备可根据该信息调度终端设备，例如分配/指示资源，指示信道检测方式，指示终端设备如何根据信道检测结果发送数据。
在一个实施方式中，终端设备可以向所述网络设备发送指示信息(称为第五指示信息)，该第五指示信息直接或间接指示了该终端设备的能力，该能力直接或间接表征了该终端设备是否支持在信道检测后的一定时间范围以内切换发送带宽，和/或该 终端设备是否支持在上述一个载波的两个或两个以上带宽单元中的不连续的带宽单元上同时发送上行传输。
在本实施方式中，如果网络设备已经获知终端设备不具备上述能力，或者说，终端设备不支持，则网络设备不允许其在部分带宽单元空闲时发送上行传输，以免影响其他设备的数据收发。以上只是举例说明，可选的，网络设备还可以指示哪些信号和/或信道可以在部分带宽单元空闲时发送上行传输，或者指示哪些信号和/或信道可以在全部带宽单元空闲时发送上行传输。图6是本实施例的方法的一个整体流程图，在该流程图中，描述了终端设备可能的行为，然而如前所述，根据信道检测结果或者根据网络设备的指示或者根据自身能力或者根据预定义的规则，某些步骤是可选的。并且，还可以增加某些步骤或者减少某些步骤。
如图6所示，该方法包括：
步骤601：上报能力；
步骤602：根据网络设备的指示从网络设备获取资源；
步骤603：根据预定义的规则和/或网络设备的指示进行信道检测；如果信道检测结果为无空闲，则执行步骤604；如果信道检测结果为部分空闲且不连续，则执行步骤605；如果信道检测结果为部分空闲且连续，则执行步骤606；如果信道检测结果为全部空闲，则执行步骤607或步骤609；
步骤604：确认上行传输发送失败，返回步骤602重新获取资源或者返回步骤603在下一个资源上重新进行信道检测；
步骤605：根据预定义的规则和/或网络设备的指示判断是否发送上行传输；如果判断为否，则回到步骤604，如果判断为是，则执行步骤607；
步骤606：根据预定义的规则和/或网络设备的指示判断是否发送上行传输；如果判断为否，则回到步骤604，如果判断为是，则执行步骤607；
步骤607：根据预定义的规则和/或网络设备的指示选择或确定带宽单元；
步骤608：根据预定义的规则和/或网络设备的指示切换发送带宽；
步骤609：发送上行传输。
根据本实施例的方法，终端设备可以在一个载波的两个或两个以上的带宽单元进行信道检测，确定各带宽单元是否忙碌或空闲，从而可以更快地开始或完成数据传输。

实施例3
本实施例提供了一种上行传输装置，该装置可以配置于终端设备。由于该装置解决问题的原理与实施例1的方法类似，因此其具体的实施可以参照实施例1的方法的实施，内容相同之处不再重复说明。
图13是本实施例的上行传输装置的示意图，请参照图13，该上行传输装置1300包括：检测单元1301和第一发送单元1302。检测单元1301用于在一个载波的两个或两个以上带宽单元上进行信道检测；第一发送单元1302用于根据所述信道检测的结果在至少一个带宽单元上发送上行传输，该至少一个带宽单元被检测为空闲。
在本实施例中，如图13所示，该装置1300还可以包括：

在本实施例中，上述至少一个资源中的一个资源是指用于一个完整上行传输的时频资源。
