本申请主张在2020年7月22日在中国提交的中国专利申请号No.202010712722.5的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种取消传输的方法、终端及网络侧设备。
背景技术
非授权频段(unlicensed band)可以作为授权频段(licensed band)的补充，以帮助运营商对通信服务进行扩容。由于非授权频段由多种技术共用，例如：无线保真(Wireless Fidelity，WiFi)、雷达、长期演进授权辅助接入(Long Term Evolution-Licensed Assisted Access，LTE-LAA)等，因此，对于非授权频谱，通信设备(如网络侧设备或终端)在进行传输前需要探侧信道是否空闲，即进行先听后说(Listen Before Talk，LBT)，如果信道空闲才能进行传输。否则，将等待下一次进行信道探测。
此外，在非授权频段上的传输还需要满足占用信道带宽(Occupied Channel Bandwidth，OCB)要求，因此在非授权频段上的传输可采用交织(interlace)方式进行资源分配。为提高非授权频段的资源利用率，多个终端可复用非授权频段资源，但是，多终端复用非授权频段资源时，若发生调度冲突，终端和网络侧设备将无法进行传输，导致传输失败。
发明内容
本申请实施例的目的是提供一种取消传输的方法、终端及网络侧设备，能够解决因非授权频段调度冲突，导致的传输失败问题。

第四方面，本申请实施例提供了一种取消传输的装置，该装置包括：

第六方面，本申请实施例提供了一种网络侧设备，该网络侧设备包括处理器、存储器及存储在存储器上并可在处理器上运行的程序或指令，程序或指令被处理器执行时实现如第三方面的取消传输的方法的步骤。
第七方面，本申请实施例提供了一种可读存储介质，可读存储介质上存储程序或指令，程序或指令被处理器执行时实现如第一方面的取消传输的方法的步骤，或者实现如第三方面的取消传输的方法的步骤。
第八方面，本申请实施例提供了一种芯片，芯片包括处理器和通信接口，通信接口和处理器耦合，处理器用于运行网络侧设备程序或指令，实现如第一方面的取消传输的方法，或实现如第三方面的取消传输的方法。
第九方面，本申请实施例提供了一种计算机软件产品，所述计算机软件产品被存储在非易失的存储介质中，所述软件产品被配置成被至少一个处理器执行以实现如第一方面的取消传输的方法的步骤，或者实现如第三方面的 取消传输的方法的步骤。
第十方面，提供了一种通信设备，所述通信设备被配置成用于执行如第一方面的取消传输的方法，或者执行如第三方面的取消传输的方法。
在本申请实施例中，终端可根据CI取消非授权频段中目标交织上的传输，可避免因非授权频段的调度冲突而导致的传输失败的问题，提高了非授权频段的业务传输可靠性，此外，本申请实施例的CI是针对交织的，在获取到CI时，只需要取消CI指示的目标交织上的上行传输，而无需取消整块资源上的上行传输，这样可提高非授权频段的资源利用率。

具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用，如第6代(6 th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，PUE)等终端侧设备，可穿戴式设备包括：手环、耳机、眼镜等。需要说明的是，在本申请实施 例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(evolved Node B，eNB)、家用B节点、家用演进型B节点、无线局域网(wireless local area network，WLAN)接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
在非授权频段传输场景下，为提高非授权频段的资源利用率，终端和基站之间、终端和终端之间可共享非授权频段。当多个终端调度冲突时，这些终端均尝试接入信道，可能会导致信道抢占失败，终端无法进行传输的问题。对此本申请实施例提供了一种非授权频段下取消传输的方法，下面将结合附图对其进行说明。
如图2所示，本申请实施例的非授权频段下取消传输的方法包括如下步骤：
步骤21：网络侧设备向终端发送取消指示CI。
其中，CI用于指示终端取消之前调度的传输，或指示终端之前调度的传输被取消。具体地，若之前被调度的传输落在CI指示的资源范围内，终端将取消之前调度的传输或确定之前调度的传输被取消。可选地，网络侧设备可通过下行控制信息(Downlink Control Information，DCI)发送CI，如通过DCI格式2_4(DCI format 2_4)。
步骤22：终端接收该CI。
相应地，终端可基于DCI，接收该CI。可选地，CI中可携带终端标识(UE ID)或终端组标识(UE group ID)以指示哪个或哪些终端取消指定资源范围内的传输。
步骤23：终端根据该CI，取消目标交织上的上行传输。
其中，目标交织是根据CI确定的。可选地，CI中可携带交织指示信息，以指示终端取消哪个交织上传输。其中，交织指示信息包括但不限于：参考 时间区域、时域粒度、参考频率区域以及频域粒度等。
可选地，本申请实施例的取消传输方法还包括：网络侧设备通过无线资源控制(Radio Resource Control，RRC)发送CI的配置信息，相应地，终端通过RRC接收CI的配置信息。其中，配置信息中携带有CI中至少部分参数的可选值。例如，参考时间区域、时域粒度、参考频率区域以及频域粒度等信息，可以是网络侧设备通过高层信令配置下来的，如通过RRC配置一组参数可选值，再通过DCI携带的CI指示具体哪个交织上的传输需要取消。
这样，网络侧设备在多个终端调度冲突时，可通过CI指示终端取消在冲突资源上的传输，从而保证特定终端在冲突资源上的传输，保证特定终端的传输可靠性。另外，CI是基于交织粒度指示的，这样不影响其他交织上的传输，可避免取消非冲突交织上的传输，从而保证了非授权频段的资源利用率。
下面将结合附图，通过具体的实施例及其应用场景，从终端侧和网络侧设备侧分别对本申请实施例的非授权频段下取消传输的方法做进一步说明。
如图3所示，本申请实施例的非授权频段下取消传输的方法，应用于终端，包括：
步骤31：终端获取取消指示CI。
CI用于指示终端取消之前调度的全部或部分传输被取消。具体地，若之前被调度的传输落在CI指示的资源范围内，终端将取消之前调度的全部或部分传输。
可选地，CI至少包括以下参数中的至少一项：CI包含的比特数、参考时间区域(reference time region)、时域粒度(time domain granularity)、参考频率区域(reference frequency region)以及频域粒度(frequency domain granularity)。此外，CI中还可包括终端的标识信息，用于指示哪个终端取消传输，或指示取消针对哪个终端传输。
步骤32：终端根据CI，取消目标交织上的上行传输。
终端在获取到CI后，基于CI指示的目标交织(interlace)，确定取消在该目标交织上的上行传输，以避免影响其他终端在该目标交织上的正常传输。或者，本申请实施例还可应用于取消下行传输，根据CI，取消目标离散资源上的下行传输，即基于CI指示的目标离散资源，确定网络侧设备取消了该目 标离散资源上的下行传输，避免了不必要的数据接收和解调操作。可选地，步骤32包括：若上行传输的传输资源与CI指示的目标交织发生重叠，则取消目标交织上的上行传输。或者，若下行传输的传输资源与CI指示的目标离散资源重叠，则在解码时排除目标离散资源上的下行传输。也就是说，如果一个终端的任何interlace中任何RB的部分或全部资源与CI指示的时频资源重叠，那么该终端取消该interlace的传输。具体地可以仅取消该interlace中重叠部分资源上的传输，或者，取消该整个interlace上的传输，即包括该interlace中不重叠的部分。需要说明的是，如果一个终端被调度的资源被CI指示取消，那么如果配置保护带(GuardBand)，其配置的GuardBand的资源也被取消。
值得指出的是，本申请实施例的取消传输的方法即可适用于取消上行传输，又可适用于取消下行传输，其中，取消下行传输的方案与取消上行传输的方案类似，故本申请实施例仅以取消上行传输作为示例性说明，本领域技术人员可以理解取消下行传输的具体实现方式可参见取消上行传输的实现方式，故不再赘述。
在本申请实施例中，对于授权频段，为提高资源利用率，引入了终端间复用(inter UE multiplexing)，当发生终端间调度冲突时，网络侧设备可以指示某些终端取消已经被调度的业务，用于突然到达的具有更高优先级的业务的传输。网络侧设备通过DCI发送上行CI指示，如果之前被调度的终端的分配的资源落在CI指示的时频区域内，终端将取消之前被调度的传输。其中，CI指示的资源是基于2D位图(bitmap)的资源分配的，例如通过2bit*3bit分别指示时域资源和频域资源。对于非授权频段可采用与授权频段类似的CI指示方式，以图4所示，假设子载波间隔为15kHz，若采用2bit*3bit的CI指示方式，CI指示的区域在时域上指示2个符号，在频域上指示3个物理资源块(Physical Resource Block，PRB)或称为资源块(Resource Block，RB)，即RB1、RB2、RB3，终端1、终端2、终端3、终端4以交织的形式调度4个interlace，当这4个终端中存在与其他终端发生调度冲突的终端时，网络侧设备可发送CI指示相应终端取消传输，其中，当某个终端的interlace至少有1个RB与CI指示的资源重叠，那么终端需要取消在对应interlace上的传输。
如图4所示，如果CI指示的时频域颗粒度比较粗，例如频域粒度为3个RB，对应于3个interlace终端1、2或3分别被调度一个interlace，只要有一个终端发生调度冲突，即使其余两个interlace的调度并没有冲突，如果CI指示取消，那么这3个终端均需要取消传输，这导致不需要取消的终端也基于CI的指示取消了被调度的传输，导致资源利用率下降。
由于非授权频谱通常以20MHz为单位，可用的interlace与子载波间隔(Sub-Carrier Spacing，SCS)相关，不同的子载波对应有不同的interlace数量。以子载波间隔为15kHz为例，一共有10个interlace，如果要指示每一个interlace，那么CI指示的频域粒度所需要的指示比特的数量大于或等于10；以子载波间隔为30kHz为例，一共有5个interlace，如果要指示每一个interlace，那么，CI指示的频域粒度所需要的指示比特的数量大于或等于5。
可选地，CI包含的比特数、时域粒度和频域粒度满足以下关系之一：CI包含的比特数为：时域粒度与频域粒度的乘积；或者，CI包含的比特数为：时域粒度与频域粒度的和值，例如频域的取消指示应用于所有的时域符号。假设CI包含的比特数为N CI，时域粒度的比特数为G CI，频域粒度的比特数为N BI，那么N CI＝G CI×N BI，也就是说，N BI＝N CI/G CI。
其中，频域粒度可以是网络侧设备配置的、预定义的、或根据CI包含的比特数和时域粒度确定的。例如频域粒度N BI由RRC配置，CI的bit数等于频域粒度的bit数乘以时域粒度的bit数。对于15kHz，由10bit以bitmap形式指示取消的interlace；对于30kHz，由5bit以bitmap形式指示取消的interlace。或者，由计算得到N BI＝N CI/G CI，保证N BI比特数大于等于10(15kHz)或者5(30Khz)。对于15kHz，N BI≥10，N BI的最高有效位(Most Significant Bit，MSB)或最低有效位(Least Significant Bit，LSB)的前10bit，以bitmap形式指示每一个interlace；对于30kHz，N BI≥5，N BI的MSB或LSB的前5bit，以bitmap形式指示每一个interlace。
以上以一个资源块集(RB set)上CI作为示例性说明，当有n个RB set需要进行取消传输时，可采用类似的方式进行。具体地，在一个载波包含多个资源块集的情况下，获取取消指示CI的步骤包括：获取多个资源块集各自对应的CI；根据所述CI，取消目标交织上的上行传输的步骤，包括：根据资 源块集各自对应的CI，取消对应目标交织上的上行传输。也就是说，当有n个RB set需要进行取消指示的时候，承载CI的DCI中包含每个RB set的取消指示信息。
假设N个载波的CI通过同一DCI指示，如图5所示，承载CI的DCI中包含N个载波的CI，一个载波下具有n个RB set，对应于一个载波的CI中包括n个指示RB set的CI，如。N_1,…,N_n可以表示n个RB set的CI。
或者，在一个载波包含至少一个资源块集的情况下，获取取消指示CI的步骤包括：获取至少一个资源块集对应的一个参考CI；根据所述CI，取消目标交织上的上行传输的步骤，包括：根据参考CI，取消对应目标交织上的上行传输。也就是说，当有N个RB set需要进行取消指示的时候，承载CI的DCI中只包含一个参考RB set的取消指示信息，参考RB set的取消指示用于所有RB set，如果一个终端监测到参考RB set的CI信息与其被调度的interlace重叠，那么终端将取消被调度的上行传输。
假设N个载波的CI通过同一DCI指示，如图6所示，承载CI的DCI中包含N个载波的CI，一个载波下具有n个RB set，对应于一个载波的CI中包括1个RB set参考的CI。如果一个终端接收到CI指示，该终端调度的任何interlace与CI指示的RB set参考中的任何interlace重叠，终端将取消相应的传输。该RB set参考可以不是一个实际的RB set，该RB set的取消指示可以视为对一个载波或BWP上，任何RB set有效。
进一步地，CI指示除包括RB set参考外，还可进一步包括RB set指示(indication)，以指示CI是作用于哪些RB set的。如图7所示，承载CI的DCI中包含N个载波的CI，一个载波下具有n个RB set，对应于一个载波的CI中包括1个RB set参考的CI，以及指示CI在哪些RB set生效的RB set指示。假设网络侧设备配置了5个RB set，那么CI包括5bit的RB set指示域，以指示取消指示的作用范围，即对哪些RB set有效。例如RB set指示域为00101，那么取消指示作用于第三个和第五个RB set，如果终端调度的资源与第三或第五个RB set相应的资源重叠，那么将取消传输。
进一步地，CI也可以仅包括RB set指示，以指示取消指示是针对哪些RB set。如图8所示，承载CI的DCI中包含N个载波的CI，一个载波下具有n 个RB set，对应于一个载波的CI中包括指示CI在哪些RB set生效的RB set指示。假设网络侧设备配置了5个RB set，那么CI包括5bit的RB set指示域，以指示取消指示的作用范围，即对哪些RB set有效。例如RB set指示域为00101，那么取消指示作用于第三个和第五个RB set，如果终端调度在第三或第五个RB set上，那么将取消传输。
这样，终端可根据CI取消非授权频段中目标交织上的传输，可避免因非授权频段的调度冲突而导致的传输失败的问题，提高了非授权频段的业务传输可靠性，此外，本申请实施例的CI是针对交织的，在获取到CI时，只需要取消CI指示的目标交织上的上行传输，而无需取消整块资源上的上行传输，这样可提高非授权频段的资源利用率。
以上从终端侧介绍了本申请取消传输的方法，下面将结合附图从网络侧设备对取消传输的方法做进一步说明。
如图9所示，本申请实施例提供了一种取消传输的方法，包括以下步骤：
步骤91：网络侧设备发送取消指示CI，其中CI用于指示取消上行传输的目标交织。

可选地，本申请实施例的取消传输方法还包括：网络侧设备通过RRC发送CI的配置信息，配置信息中携带有CI中至少部分参数的可选值。例如，参考时间区域、时域粒度、参考频率区域以及频域粒度等信息，可以是网络侧设备通过高层信令配置下来的，如通过RRC配置一组参数可选值，再通过DCI携带的CI指示具体哪个交织上的传输需要取消。
进一步地，CI包含的比特数、时域粒度和频域粒度满足以下关系之一：CI包含的比特数为：时域粒度与频域粒度的乘积；CI包含的比特数为：时域粒度与频域粒度的和值。频域粒度可以是网络侧设备配置的、预定义的、或根据CI包含的比特数和时域粒度确定的。具体确定方式可参照上述终端侧实 施例，故在此不再赘述。
可选地，步骤91可以包括：在上行传输之前，发送CI，以保证终端在进行上行传输之前接收到指示取消上行传输的CI，以及时取消上行传输，保证其他终端的传输。
这样，网络侧设备发送CI以指示终端取消目标交织上的上行传输，终端可根据CI取消非授权频段中目标交织上的传输，可避免因非授权频段的调度冲突而导致的传输失败的问题，提高了非授权频段的业务传输可靠性，此外，本申请实施例的CI是针对交织的，在获取到CI时，只需要取消CI指示的目标交织上的上行传输，而无需取消整块资源上的上行传输，这样可提高非授权频段的资源利用率。
