在第五代移动通信技术(the 5th Generation Mobile Communication Technology，5G)技术新一代无线通信(New Radio，NR)中，同一用户设备(User Equipment，UE)可以支持不同类型的业务，例如支持增强移动宽带(Enhanced Mobile Broadband，eMBB)业务传输以及与eMBB业务相关的上行信道的传输，也可以同时支持高可靠低时延通信(Ultra Reliable Low Latency Communication，URLLC)业务传输以及与URLLC业务相关的上行信道的传输。但是考虑到UE实现的复杂度，一个UE允许在某一时间段内仅传输一个上行信道，例如，UE存在两个上行信道出现时域重叠时，UE只能选择传输其中的一个。另一个应该被全部取消或者部分取消。
在NR的讨论中，提出同一UE的多个上行传输信道时域重叠时，低优先级的上行传输将被全部或部分取消传输，高优先级的上行传输正常传输，但是考虑到低优先级的上行传输被取消，造成低优先级的上行传输被重传，如果上行传输是控制信令，例如，混合自动重传请求-确认(Hybrid Automatic Repeat Request Acknowledgement，HARQ-ACK)物理上行控制信道(Physical Uplink Control Channel，PUCCH)，则需要重传HARQ-ACK对应的下行数据。直接的取消低优先级的上行传输，会使得低优先级的上行传输效率降低。

具体实施方式
下文中将结合附图对本申请的实施例进行说明。
图1是本申请实施例中信道冲突的示例图，参见图1，以一个HARQ-ACK PUCCH和另一个物理上行共享信道(Physical Uplink Shared Channel，PUSCH)(带有上行数据)的传输资源时域重叠为例，其中，高优先级上行信道为HARQ-ACK PUCCH，低优先级上行信道为PUSCH，HARQ-ACK PUCCH与PUSCH传输资源时存在时域重叠部分，造成HARQ-ACK PUCCH与PUSCH冲突，在一些情况下，低优先级上行信道已经开始传输了，此时才开始出现高优先级上行信道，可以通过设置一个合理的开始取消位置，从而解决实际传输时由于信道冲突导致的低优先级上行信道上行传输效率低的问题。
图2是本申请实施例提供的一种信道冲突处理方法的流程图，本申请实施例可以适用于资源传输的信道冲突的情况，该方法可以由本申请实施例中的信道冲突处理装置中来执行，该装置可以由软件和/或硬件的方式实现，参见图1，本申请实施例提供的方法具体包括如下步骤：
步骤101、同一UE的高优先级上行信道与低优先级上行信道的传输资源时域重叠时，确定所述低优先级上行信道的取消传输开始位置。
高优先级上行信道为可以优先进行资源传输的信道，当高优先级上行信道和低优先级上行信道同时传输资源时，可以由高优先级上行信道优先传输资源，等待高优先级上行信道内的资源传输完毕后再由低优先级上行信道传输资源。
在本申请实施例中，时域重叠可以是指高优先级上行信道和低优先级上行信道在传输资源时存在资源传输的时间存在重合的部分，例如，低优先级上行信道传输资源还未结束时，高优先级上行信道已经开始传输资源，此时低优先级信号和高优先级上行信道存在时域重叠。取消传输开始位置可以是信道冲突时取消低优先级上行信道传输资源的开始位置，由于直接取消低优先级上行信道的资源传输会使得低优先级上行信道的上行传输效率降低，通过确定取消传输开始位置，可以在重传时仅传输被取消的低优先级上行信道的传输资源，从而提升低优先级上行信道的上行传输效率。
当确定UE的多个上行传输信道的传输资源时域重叠时，可以根据上行传输信道的高优先级上行信道确定出取消低优先级上行信道资源传输的开始位置。
步骤102、根据所述取消传输开始位置取消所述低优先级上行信道的传输资源。
在本申请实施例中，可以根据取消传输开始位置取消低优先级上行信道的传输资源，具体可以是全部取消，也可以是部分取消，例如，可以取消低优先级上行信道中取消传输开始位置后的部分传输资源，在进行重传时，可以仅重传取消的低优先级上行信道中的部分传输资源。
本申请实施例的技术方案，通过在高优先级上行信道与低优先级上行信道存在传输资源时域重叠时，确定低优先级上行信道对应的取消传输开始位置，通过取消传输开始位置取消低优先级上行信道的传输资源，降低高优先级上行信道对低优先级上行信道传输资源的影响，提高了低优先级上行信道的传输效率。
图3是本申请实施例提供的一种信道冲突处理方法的流程图，本申请实施例对确定取消传输开始位置的方式进行说明，参见图3，本申请实施例的方法具体包括如下操作：
步骤201、当高优先级上行信道与低优先级上行信道的传输资源时域重叠时，将所述高优先级上行信道对应信道的末尾符号之后阈值间隔后的位置确定为所述取消传输开始位置。
末尾符号可以是在时域下高优先级上行信道对应信道的最后一个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，对应的信道可以是PDSCH或者PDCCH，具体可以是该末尾符号的结束位置。阈值间隔可以是确定取消低优先级上行信道传输资源的间隔，阈值间隔的开始位置可以是高优先级上行信道对应信道的末尾符号，阈值间隔的结束位置可以是低优先级对应的取消传输开始位置。
在本申请实施例中，当UE的高优先级上行信道和低优先级上行信道在传输资源时存在时域重叠的情况，可以确定出高优先级上行信道传输资源对应PDSCH的结束位置，具体可以是高优先级上行信道的末尾处的OFDM符号，可以将该OFDM符号作为高优先级上行信道传输资源的末尾符号，可以从末尾符号后距离阈值间隔的位置作为取消传输开始位置。
一种实施方式中，阈值间隔包括以下至少一种：时间量间隔或OFDM符号间隔。
阈值间隔可以是时间量间隔，也可以是OFDM符号间隔，可以理解的是，当阈值间隔可以同时为时间量间隔和OFDM符号间隔时，时间量间隔与OFDM符号间隔之间可以存在转换关系，例如，可以通过预先约定的转换系数，将时间量间隔和OFDM符号间隔之间进行转换。在一实施例中，间隔阈值可以是标准TS38.214中的T proc,1，还可以是N，N1，T proc,2，N2，或N3中的任意一个， 也可以是预先约定好的值，N，N1，N2，N3可以是TS38.214或TS38.213中定义的OFDM符号间隔、T proc,1和T proc,2可以是TS38.214或TS38.213中定义的时间量间隔。
在一种实施方式中，阈值间隔包括第一阈值间隔和第二阈值间隔，或者所述阈值间隔包括第一阈值间隔。
在本申请实施例中，阈值间隔可以由第一阈值间隔和第二阈值间隔构成，其中，第二阈值间隔可以是可选的，例如，阈值间隔可以为B，其中，第一阈值间隔为B1，第二阈值间隔可以为B2，其中，B＝B1+B2，B1是必选的，B2是可选的，当B2不存在时，阈值间隔B＝B1。B1可以是标准TS38.214中的T proc,1，还可以是N，N1，T proc,2，N2，或N3中的任意一个，也可以是预先约定好的值，N，N1，N2，N3可以是TS38.214或TS38.213中定义的OFDM符号间隔、T proc,1和T proc,2可以是TS38.214或TS38.213中定义的时间量间隔。B2可以是0、1和2等OFDM符号中的一个，可以根据UE的上报的处理能力确定，例如，这里如果B1为T proc,1，则设置T proc,1中的d 1,1＝0。如果B1被定义为T proc,2，则设置T proc,2中的d 2,1＝0。
步骤202、从所述取消传输开始位置取消所述低优先级上行信道的传输资源。
低优先级上行信道传输资源的开始OFDM符号，可以将该OFDM符号作为低优先级上行信道传输资源的开始位置。可以将开始位置与取消传输开始位置进行比较，可以根据开始位置与取消传输开始位置的前后关系确定取消低优先级上行信道传输资源的方式，可以理解的是，在本申请实施例中，取消低优先级上行信道传输资源的方式可以包括取消低优先级上行信道传输的全部资源，也可以包括取消低优先级上行信道传输在取消传输开始位置后的部分资源。
示例性的，图4是本申请实施例提供的一种信道冲突处理方法的示例图，图4中以半静态传输的半静态调度(Semi-Persistent Scheduling，SPS)PDSCH为例，高优先级上行信道HARQ-ACK PUCCH与低优先级上行信道PUSCH时域重叠，则从HARQ-ACK PUCCH对应的SPS PDSCH最后符号的末尾之后间隔B的C处作为低优先级上行信道PUSCH的取消传输开始位置。也就是说低优先级上行信道PUSCH如果在C处仍然没有传输结束，则取消C处之后的资源传输，如果低优先级上行信道PUSCH在C处或者之前已经传输结束，则可以意味着低优先级上行信道PUSCH实际完整的传输，在本申请实施例中，间隔B可以包括B1和B2，其中，B1是必选的，B2是可选的。B1可以是标准TS38.214中的T proc,1，还可以是N，N1，T proc,2，N2，或N3中的任意一个，也可以是预先约定好的值，N，N1，N2，N3可以是TS38.214或TS38.213中定义的OFDM符号间隔、T proc,1 和T proc,2可以是TS38.214或TS38.213中定义的时间量间隔。B2可以是0、1和2等OFDM符号中的一个，可以根据UE的上报的处理能力确定，例如，这里如果B1为T proc,1，则设置T proc,1中的d 1,1＝0。如果B1被定义为T proc,2，则设置T proc,2中的d 2,1＝0。
当HARQ-ACK PUCCH与PUSCH对应的PDCCH使用的子载波间隔不完全相同时，则从他们使用的子载波间隔中取得使得间隔B最大的子载波间隔来确定间隔B，可以具体指时间量间隔最大。如果C处对应到低优先级PUSCH传输的某一OFDM符号中(非OFDM符号末尾)，则低优先级PUSCH被取消从该OFDM符号开始。这是因为确定C处时使用的子载波间隔与低优先级PUSCH使用的子载波间隔不同，可能导致C处映射到低优先级PUSCH传输的符号时，没有对应到一个符号的边界。这样，在一些情况下，低优先级的PUSCH可能被传输至C处，这种情况下，低优先级上行信道具有明确的结束位置，便于基站解码，以及基于码块组(Code Block Group，CBG)的部分重传机制，从而提升低优先级PUSCH传输效率。
本申请实施例的技术方案，通过在高优先级上行信道与低优先级上行信道的传输资源时域重叠时，将高优先级上行信道对应信道的末尾符号之后阈值间隔的位置确定为取消传输开始位置，获取低优先级上行信道传输资源的开始位置，通过开始位置和取消传输开始位置取消低优先级上行信道传输资源，实现了取消低优先级上行信道资源传输的控制，降低高优先级上行信道对低优先级上行信道的影响，提高了低优先级信道的传输效率。
在一个实施方式中，所述确定所述低优先级上行信道的取消传输开始位置，包括：
将所述高优先级上行信道的开始符号之前阈值间隔前的位置确定为所述取消传输开始位置。
可以在UE的高优先级上行信道和低优先级上行信道在传输资源时存在时域重叠的情况，可以确定出高优先级上行信道传输资源的开始位置，具体可以是高优先级上行信道的开始的OFDM符号，可以将该OFDM符号作为高优先级上行信道传输资源的开始符号，可以从开始符号前方距离阈值间隔的位置作为取消传输开始位置。
在本申请实施例中，低优先级上行信道的取消传输开始位置，其中，开始位置可以是符号位置或者时间点，以开始位置为符号位置为例，开始位置具体可以是允许低优先级上行传输到的最晚符号，之后不能再继续传输低优先级上行传输，也就是之后低优先级上行传输如果未传输结束就需要取消剩余传输。或者，低优先级上行信道的取消传输开始位置，也可以是低优先级上行传输必 须传输到该开始位置(如果低优先级上行传输的结束位置晚于该开始位置)。其中，该开始位置作为边界符号位置，其处理方式可以是预先约定的，例如，如果约定该开始位置的符号包含在取消的符号内，则取消从该开始位置的符号开始，如果约定该开始位置的符号不包含在取消的符号内，则取消从该开始位置的符号之后开始。示例性的，图5是本申请实施例提供的一种信道冲突处理方法的示例图，以一个UE高优先级上行信道HARQ-ACK PUCCH和该UE的低优先级上行信道PUSCH时域重复为例，可以从高优先级上行信道HARQ-ACK PUCCH的开始符号向前间隔B的C处作为低优先级PUSCH的取消传输的开始位置，也就是说低优先级上行信道HARQ-ACK PUCCH如果在C处仍然没有传输结束，则取消C处之后的资源传输，如果低优先级上行信道在C处或者之前已经传输结束，则可以意味着低优先级上行信道PUSCH实际完整的传输，在本申请实施例中，间隔B可以包括B1和B2，其中，B1是必选的，B2是可选的。B1可以是标准TS38.214中的T proc,1，还可以是N，N1，T proc,2，N2，或N3中的任意一个，也可以是预先约定好的值，N，N1，N2，N3可以是TS38.214或TS38.213中定义的OFDM符号间隔、T proc,1和T proc,2可以是TS38.214或TS38.213中定义的时间量间隔。B2可以是0、1和2等OFDM符号中的一个，可以根据UE的上报的处理能力确定，例如，这里如果B1为T proc,1，则设置T proc,1中的d 1,1＝0。如果B1被定义为T proc,2，则设置T proc,2中的d 2,1＝0。
当HARQ-ACK PUCCH与PDSCH对应的PDCCH使用的子载波间隔不完全相同时，则从他们使用的子载波间隔中取得使得间隔B最大的子载波间隔来确定间隔B，可以具体指时间量间隔最大。如果C处对应到低优先级PUSCH传输的某一OFDM符号中(非OFDM符号末尾)，则低优先级PUSCH被取消从该OFDM符号开始。这是因为确定C处时使用的子载波间隔与低优先级PUSCH使用的子载波间隔不同，可能导致C处映射到低优先级PUSCH传输的符号时，没有对应到一个符号的边界。这样，在一些情况下，低优先级的PUSCH可能被传输至C处，这种情况下，低优先级上行信道具有明确的结束位置，便于基站解码，以及基于码块组CBG的部分重传机制，从而提升低优先级PUSCH传输效率。
一种实施方式中，高优先级上行信道为HARQ-ACK PUCCH，相应的，所述当高优先级上行信道与低优先级上行信道的传输资源时域重叠时，确定所述低优先级上行信道的取消传输开始位置，包括：
当HARQ-ACK PUCCH与低优先级上行信道的传输资源时域重叠，所述HARQ-ACK PUCCH对应的PDSCH的末尾符号之后的阈值间隔处作为所述低优先级上行信道的取消传输开始位置。
图6是本申请实施例提供的一种取消传输开始位置确定的示例图，参见图6，以高优先级上行信道为HARQ-ACK PUCCH，低优先级上行信道为PUSCH为例，如果一个UE的高优先级上行信道HARQ-ACK PUCCH和这个UE的低优先级上行信道PUSCH时域重叠，则从HARQ-ACK PUCCH对应的PDSCH最后符号的末尾之后间隔B的C处作为低优先级上行信道PUSCH的取消传输开始位置。也就是说低优先级上行信道PUSCH如果在C处仍然没有传输结束，则取消C处之后的资源传输，如果低优先级上行信道在C处或者之前已经传输结束，则可以意味着低优先级上行信道PUSCH实际完整的传输，在本申请实施例中，间隔B可以包括B1和B2，其中，B1是必选的，B2是可选的。B1可以是标准TS38.214中的T proc,1，还可以是N，N1，T proc,2，N2，或N3中的任意一个，也可以是预先约定好的值，N，N1，N2，N3可以是TS38.214或TS38.213中定义的OFDM符号间隔、T proc,1和T proc,2可以是TS38.214或TS38.213中定义的时间量间隔。B2可以是0、1和2等OFDM符号中的一个，可以根据UE的上报的处理能力确定，例如，这里如果B1为T proc,1，则设置T proc,1中的d 1,1＝0。如果B1被定义为T proc,2，则设置T proc,2中的d 2,1＝0。
当HARQ-ACK PUCCH与PUSCH对应的PDCCH使用的子载波间隔不完全相同时，则从他们使用的子载波间隔中取得使得间隔B最大的子载波间隔来确定间隔B，可以具体指时间量间隔最大。如果C处对应到低优先级PUSCH传输的某一OFDM符号中(非OFDM符号末尾)，则低优先级PUSCH被取消从该OFDM符号开始。这是因为确定C处时使用的子载波间隔与低优先级PUSCH使用的子载波间隔不同，可能导致C处映射到低优先级PUSCH传输的符号时，没有对应到一个符号的边界。这样，在一些情况下，低优先级的PUSCH可能被传输至C处，这种情况下，低优先级上行信道具有明确的结束位置，便于基站解码，以及基于码块组CBG的部分重传机制，从而提升低优先级PUSCH传输效率。
一种实施方式中，高优先级上行信道为非周期信道状态信息(Aperiodic Channel State Information，A-CSI)PUSCH，相应的，所述当高优先级上行信道与低优先级上行信道的传输资源时域重叠时，确定所述低优先级上行信道的取消传输开始位置，包括：
当A-CSI PUSCH与低优先级上行信道的传输资源时域重叠时，所述A-CSI PUSCH对应的PDCCH末尾符号之后阈值间隔处作为所述低优先级上行信道的取消传输开始位置。
在一实施例中，在上述申请实施例的基础上，阈值间隔的取值为T proc,CSI和T′ proc,CSI中最晚的间隔值，其中，所述T procCSI和T′ proc,CSI为标准TS38.214和 TS38.213中的定义值。
一种实施方式中，高优先级上行信道为A-CSI PUCCH，相应的，所述当高优先级上行信道与低优先级上行信道的传输资源时域重叠时，确定所述低优先级上行信道的取消传输开始位置，包括：
当A-CSI PUCCH与低优先级上行信道的传输资源时域重叠时，所述A-CSI PUCCH对应的PDCCH末尾符号之后阈值间隔处作为所述低优先级上行信道的取消传输开始位置。
图7是本申请实施例提供的一种取消传输开始位置确定的示例图，参见图7，UE的一个被PDCCH触发的高优先级的非周期信道状态信息A-CSI通过PUSCH传输，且该PUSCH不携带上行数据。在一实施例中，A-CSI还可以通过PUCCH传输。该高优先级上行信道A-CSI PUSCH与一个低优先级PUSCH时域冲突时，为了最大化低优先级上行信道PUSCH的传输效率，在发生时域重叠时，从高优先级A-CSI PUSCH对应的PDCCH最后末尾符号的间隔B之后的C处作为低优先级PUSCH的取消传输开始位置，也就是说低优先级上行信道PUCCH如果在C处仍然没有传输结束，则取消C处之后的资源传输，如果低优先级上行信道在C处或者之前已经传输结束，则可以意味着低优先级上行信道PUSCH实际完整的传输，在本申请实施例中，间隔B可以包括B1和B2，其中，B1是必选的，B2是可选的。B1可以是标准TS38.214中的T proc,CSI和T′ proc,CSI，还可以是N，N1，T proc,1，T proc,2，N2，Z，Z′或N3中的任意一个，也可以是预先约定好的值，N，N1，N2，N3可以是TS38.214或TS38.213中定义的OFDM符号间隔、T proc,1，T proc,2，T proc,CSI和T′ proc,CSI可以是TS38.214或TS38.213中定义的时间量间隔。B2可以是0、1和2等OFDM符号中的一个，可以根据UE的上报的处理能力确定，例如，这里如果B1为T proc,1，则设置T proc,1中的d 1,1＝0。如果B1被定义为T proc,2，则设置T proc,2中的d 2,1＝0。
当A-CSI PUSCH与PUSCH对应的PDCCH使用的子载波间隔不完全相同时，则从他们使用的子载波间隔中取得使得间隔B最大的子载波间隔来确定间隔B，可以具体指时间量间隔最大。如果C处对应到低优先级PUSCH传输的某一OFDM符号中(非OFDM符号末尾)，则低优先级PUSCH被取消从该OFDM符号开始。这是因为确定C处时使用的子载波间隔与低优先级PUSCH使用的子载波间隔不同，可能导致C处映射到低优先级PUSCH传输的符号时，没有对应到一个符号的边界。这样，在一些情况下，低优先级的PUSCH可能被传输至C处，这种情况下，低优先级上行信道具有明确的结束位置，便于基站解码，以及基于码块组CBG的部分重传机制，从而提升低优先级PUSCH传输效率。
一种实施方式中，高优先级上行信道为无线资源控制(Radio Resource  Control，RRC)信令配置的调度请求(Scheduling Request，SR)PUCCH或波束故障恢复(Beam Failure Recovery，BFR)PUCCH，相应的，所述当高优先级上行信道与低优先级上行信道的传输资源时域重叠时，确定所述低优先级上行信道的取消传输开始位置，包括：
当SR PUCCH或BFR PUCCH与低优先级上行信道的传输资源时域重叠时，所述SR PUCCH或所述BFR PUCCH的起始符号之前阈值间隔的位置作为所述低优先级上行信道的取消传输开始位置。
图8是本申请实施例提供的一种取消传输开始位置确定的示例图，参见图8，UE的一个高优先级上行信道SR PUCCH或BFR PUCCH，该高优先级上行信道与一个低优先级PUSCH时域冲突。可以理解的是，低优先级上行信道PUSCH也可以是低优先级上行信道HARQ-ACK PUCCH、低优先级上行信道SR PUCCH、低优先级上行信道CSI PUCCH、低优先级上行信道A-CSI PUSCH(不带UL data)、低优先级上行信道探测参考信号(Sounding Reference Signal，SRS)，或低优先级上行信道BFR PUCCH，处理方式与低优先级PUSCH时的处理方式是相同。为了最大化低优先级上行信道PUSCH的传输效率，在发生时域重叠时，将高优先级上行信道SR PUCCH或BFR PUCCH的开始符号前间隔B之前的C处作为低优先级PUSCH的取消传输开始位置，也就是说，低优先级上行信道PUCCH如果在C处仍然没有传输结束，则取消C处之后的资源传输，如果低优先级上行信道在C处或者之前已经传输结束，则可以意味着低优先级上行信道PUSCH实际完整的传输，在本申请实施例中，间隔B可以包括B1和B2，其中，B1是必选的，B2是可选的。B1可以是标准TS38.214中的T proc,CSI和T′ proc,CSI，还可以是N，N1，T proc,1，T proc,2，N2，Z，Z′或N3中的任意一个，也可以是预先约定好的值，N，N1，N2，N3可以是TS38.214或TS38.213中定义的OFDM符号间隔、T proc,1，T proc,2，T proc,CSI和T′ proc,CSI可以是TS38.214或TS38.213中定义的时间量间隔。B2可以是0、1和2等OFDM符号中的一个，可以根据UE的上报的处理能力确定，例如，这里如果B1为T proc,1，则设置T proc,1中的d 1,1＝0。如果B1被定义为T proc,2，则设置T proc,2中的d 2,1＝0。
当SR PUCCH或BFR PUCCH与PUSCH对应的PDCCH使用的子载波间隔不完全相同时，则从他们使用的子载波间隔中取得使得间隔B最大的子载波间隔来确定间隔B，可以具体指时间量间隔最大。如果C处对应到低优先级PUSCH传输的某一OFDM符号中(非OFDM符号末尾)，则低优先级PUSCH被取消从该OFDM符号开始。这是因为确定C处时使用的子载波间隔与低优先级PUSCH使用的子载波间隔不同，可能导致C处映射到低优先级PUSCH传输的符号时，没有对应到一个符号的边界。这样，在一些情况下，低优先级的PUSCH可能被传输至C处，这种情况下，低优先级上行信道具有明确的结束位置，便 于基站解码，以及基于码块组CBG的部分重传机制，从而提升低优先级PUSCH传输效率。
一种实施方式中，高优先级上行信道至少包括：HARQ-ACK PUCCH、A-CSI PUSCH、A-CSI PUCCH、SR PUCCH和BFR PUCCH中至少一种。
在另一种实施方式中，低优先级上行信道至少包括：动态PUSCH、半静态PUSCH、HARQ-ACK PUCCH、SR PUCCH、CSI PUCCH、A-CSI PUSCH、A-CSI PUCCH、SRS和BFR PUCCH中一种。

阈值间隔也可以包括B1，或者阈值间隔包括B1和B2。B1可以是TS38.214中的T proc,1，还可以是N、N1、T proc,2、N2、Z、Z’、T proc,CSI以及N3中的一个，也可以是预先约定好的值，N、N1、N2、N3、Z、Z’的单位是符号，是TS38.214或TS38.213中定义的值，T proc,1、T proc,2和T proc,CSI是时间量，可以根据实际应用情况略有调整，也是TS38.214或TS38.213中定义的值，上述的符号和时间量之间可以相互换算。如果B1为T proc,1，可以设置T proc,1中的d 1,1＝0。如果B1为T proc,2，可以设置T proc,2中的d 2,1＝0。B2的取值为0、1、2中的一个，且单位为符号，根据UE上报的处理能力确定。注意，这里的阈值间隔的时长确定方式适用上述本申请中所有实施例中的阈值间隔的时长确定。
图9是本申请实施例提供的一种取消传输开始位置确定的示例图，以一个UE的高优先级的HARQ-ACK PUCCH和这个UE的低优先级的PUSCH时域重叠为例，高优先级的HARQ-ACK PUCCH对应的PDCCH的最后符号的末尾之后间隔B的C处作为低优先级PUSCH的取消传输的开始位置。也就是说低优先级上行信道HARQ-ACK PUCCH如果在C处仍然没有传输结束，则取消C处之后的资源传输，如果低优先级上行信道在C处或者之前已经传输结束，则可以意味着低优先级上行信道PUSCH实际完整的传输。在本申请实施例中，间隔B可以包括B1和B2，其中，B1是必选的，B2是可选的。B1可以是标准TS38.214中的T proc,1，还可以是N，N1，T proc,2，N2，或N3中的任意一个，也可以是预先约定好的值，N，N1，N2，N3可以是TS38.214或TS38.213中定义的OFDM符号间隔、T proc,1和T proc,2可以是TS38.214或TS38.213中定义的时间量间隔。B2可以是0、1和2等OFDM符号中的一个，可以根据UE的上报的处理能力确定，例如，这里如果B1为T proc,1，则设置T proc,1中的d 1,1＝0。如果B1被定义为T proc,2，则设置T proc,2中的d 2,1＝0。
当HARQ-ACK PUCCH与PDSCH对应的PDCCH使用的子载波间隔不完 全相同时，则从他们使用的子载波间隔中取得使得间隔B最大的子载波间隔来确定间隔B，可以具体指时间量间隔最大。如果C处对应到低优先级PUSCH传输的某一OFDM符号中(非OFDM符号末尾)，则低优先级PUSCH被取消从该OFDM符号开始。这是因为确定C处时使用的子载波间隔与低优先级PUSCH使用的子载波间隔不同，可能导致C处映射到低优先级PUSCH传输的符号时，没有对应到一个符号的边界。这样，在一些情况下，低优先级的PUSCH可能被传输至C处，这种情况下，低优先级上行信道具有明确的结束位置，便于基站解码，以及基于码块组CBG的部分重传机制，从而提升低优先级PUSCH传输效率。相应的，当高优先级上行信道HARQ-ACK PUCCH与低优先级PUSCH之间信道冲突的处理时，传输开始位置也需要满足新的时序关系，高优先级HARQ-ACK PUCCH的起始符号，不早于该HARQ-ACK PUCCH对应的PDSCH对应的PDCCH的末尾之后间隔H的S处(如图10所示)。其中，这里间隔H的定义为：间隔H包括H1和H2，H1是必选的，H2是可选的。H1可以是TS38.214中的T proc,1，还可以是N，N1，T proc,2，N2，或N3中的一个，也可以是预先约定好的值(这里的N，N1，N2，N3单位是符号，是TS38.214或TS38.213中定义的值，T proc,1，T proc,2是符号换算为时间量，期间根据不同的情况略有调整，但也是TS38.214或TS38.213中定义的值。注意符号和时间量是可以相互换算的)，只需要事先约定好即可。这里H2如果被选定，取值为0,1,2中的一个符号，根据UE上报的处理能力确定。如果所述HARQ-ACK PUCCH，所述PUSCH以及所述PDSCH对应的PDCCH使用的子载波间隔不完全相同时，则从它们使用的子载波间隔中取使得间隔H最大的子载波间隔来确定间隔H，这里是指实际的时间间隔最大。如果S处对应到低优先级PUSCH传输的某一OFDM符号中(非OFDM符号末尾)，则低优先级PUSCH被取消从该OFDM符号开始(包括该OFDM符号)。这是因为确定S处时使用的子载波间隔与低优先级PUSCH使用的子载波间隔不同，可能导致S处映射到低优先级PUSCH传输的符号时，没有对应到一个符号的边界。
图11是一种取消传输开始位置确定的示意图，参见图11，以一个UE中UL DCI调度一个动态授权(Dynamic Grant，DG)PUSCH传输，且这个DG PUSCH传输资源和一个配置授权(Configured Grant，CG)PUSCH传输时机发生时域冲突，则这个UL DCI的发送位置被严格限制，例如，协议限制为：UL DCI的末尾到这个CG PUSCH时机的起始符号之间至少间隔N2(N2被定义在TS38.214中)。这个限制可以确保DG PUSCH被传输，因为这种情况下，UL DCI到介质访问控制(Media Access Control，MAC)层后，即使在MAC层同时有CG PUSCH也要传输，但是协议规则中，MAC层按照DG PUSCH优先传输，CG PUSCH按照被延迟的规则处理。这样的限制同时带来缺点是：如果CG  PUSCH时机处实际未进行传输，则限制了调度DG PUSCH的时机，显然对于动态调度的DG PUSCH带来约束，且由于CG PUSCH实际没有发生传输，而浪费DG PUSCH及时被调度在CG PUSCH的资源位置处。如果此时DG PUSCH具有高优先级，例如为时延要求苛刻的URLLC业务，则此时对于业务传输的影响可能是致命的。也就是，如果DG PUSCH是高优先级的，CG PUSCH是低优先级的，这种限制将不合理。所以，为了克服协议中的缺点，提出下面的改进方式，参见图12，如果基站为UE调度DG PUSCH时，DG PUSCH传输位置和UE的CG PUSCH传输时机时域重叠，且DG PUSCH是高优先级的(CG PUSCH优先级可以是高或低)，且DG PUSCH对应的UL DCI的末尾(UL DCI的最后一个符号的末尾)晚于G点，则基站希望UE处理DG PUSCH传输，丢弃CG PUSCH传输。同样的，如果UE接收到一个UL DCI调度的DG PUSCH，且DG PUSCH传输位置和UE的CG PUSCH传输时机时域重叠，且DG PUSCH是高优先级的(CG PUSCH优先级可以是高或低)，且这个UL DCI的末尾晚于G点，则UE处理DG PUSCH传输，丢弃CG PUSCH传输。G点定义为，CG PUSCH起始符号向前间隔N的位置为G点，N可以取38.214协议中的N2或T proc,2等。在一实施例中，如果基站为UE调度DG PUSCH时，DG PUSCH传输位置和UE的CG PUSCH传输时机时域重叠，且DG PUSCH和CG PUSCH具有相同优先级时，UE不期望DG PUSCH对应的UL DCI的末尾(UL DCI的最后一个符号的末尾)晚于G点，也就是基站禁止：调度UE的DG PUSCH的UL DCI的末尾(UL DCI的最后一个符号的末尾)晚于G点。G点定义为CG PUSCH起始符号向前间隔N的位置为G点，N可以取38.214协议中的N2或T proc,2等。
