Description

通信方法和通信装置
本申请要求于2018年02月14日提交中国专利局、申请号为201810152042.5、申请名称为“通信方法和通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，并且更具体的，涉及通信领域中的通信方法和通信装置。
背景技术
移动通信技术已经深刻地改变了人们的生活，但人们对更高性能的移动通信技术的追求从未停止。为了应对未来爆炸性的移动数据流量增长、海量移动通信的设备连接、不断涌现的各类新业务和应用场景，第五代(the fifth generation，5G)移动通信系统应运而生。国际电信联盟(international telecommunication union，ITU)为5G以及未来的移动通信系统定义了三大类应用场景：增强型移动宽带(enhanced mobile broadband，eMBB)、高可靠低时延通信(ultra reliable and low latency communications，URLLC)以及海量机器类通信(massive machine type communications，mMTC)。
不同业务对移动通信系统的需求不同，当前5G通信系统应当同时支持多种不同业务的数据传输需求，例如，同时支持URLLC业务和eMBB业务。由于URLLC业务的数据的突发性，为了提高系统资源利用率，网络设备通常不会为URLLC业务的数据传输预留资源。当URLLC业务数据需要传输时，如果此时没有空闲的时频资源，网络设备为了满足URLLC业务的超短时延需求，无法等待将本次调度的eMBB业务数据传输完成之后再对URLLC业务数据进行调度。网络设备可以采用抢占(preemption)的方式，为URLLC业务数据分配资源，例如，网络设备在已经分配的、用于传输eMBB业务数据的时频资源上选择部分或全部的时频资源用于传输URLLC业务数据，终端设备在这些被抢占的时频资源上停止eMBB业务的上行数据的发送。
网络设备如何指示被抢占的上行资源是亟需解决的问题。
发明内容
本申请提供一种通信方法和通信装置，能够实现网络设备向终端设备指示被抢占的上行资源。
第一方面，提供了一种通信方法，包括：
获取第一指示信息，所述第一指示信息用于指示终端设备停止当前上行数据的发送的时频资源或时域位置；
根据所述第一指示信息，确定停止当前上行数据的发送的时频资源或时域位置。
第二方面，提供了一种通信方法，包括：
确定第一指示信息，所述第一指示信息用于指示终端设备停止当前上行数据的发送的时频资源或时域位置；
发送所述第一指示信息。
本申请各实施例中，所述第一指示信息用于指示终端设备停止当前上行数据的发送的时频资源或时域位置。
其中，第一指示信息需要基于参考的时频资源或者参考的时域位置来指示时频资源或时域位置，结合第一指示信息的通知内容和参考的时频资源或者参考的时域位置可以得到停止当前上行数据的发送的时频资源或者停止当前上行数据的发送的时域位置。
一种可能的实现方式中，参考的时频资源可以是上行参考资源RUR，则停止当前上行数据的发送的时频资源可以是上行参考资源中的第一资源。所述第一指示信息也可用于指示该上行参考资源中的第一资源被占用，或者所述第一指示信息指示的是第一资源的相对的时频位置。该上行参考资源的时域范围包括灵活符号和/或上行符号。
又一种可能的实现方式中，参考的时域位置可以是上行参考资源的时域位置，时域位置可以包括一个或多个符号，则停止当前上行数据的发送的时域位置可以是上行参考资源中的第一资源的时域位置，所述第一指示信息可以用于指示该上行参考资源中的第一资源被占用，或者所述第一指示信息指示的是第一资源的相对的时域位置。该上行参考资源的时域范围包括灵活符号和/或上行符号。
又一种可能的实现方式中，参考的时域位置也可以是时域上的一个符号，则停止当前上行数据的发送的时域位置可以基于参考的时域位置进行指示，例如给出一个偏移量，所述第一指示信息可以用于指示停止当前上行数据的发送的相对于参考的时域位置的时间长度。
应理解，第一指示信息可以指示被抢占资源的时频信息，或者只指示被抢占资源的时域信息，也可以只指示被抢占资源的频域信息。例如，当第一指示信息只通知时域信息时，如第一资源的起始位置，而不需要考虑该第一资源的频域信息。此时，收到该第一指示信息的终端设备需要在第一指示信息所指示的时域位置上停止当前上行数据的发送。
还应理解，第一指示信息通知的时域信息还可以是被抢占的终端设备需要停止发送的时间，不需要和第一资源做绑定。终端设备根据第一指示信息指示的时间决定如何发送上行数据。例如，收到该第一指示信息的终端设备需要在第一指示信息所指示的时间点停止当前上行数据的发送。或者当终端设备在第一指示信息指示的时间点没有上行数据发送，但是在此时间点后的一定时间段内，有上行数据发送，则停止该上行数据发送的部分或者全部。这里停止发送的时间还可以是一个时间范围，终端设备在第一指示信息指示的这个时间范围内不发送上行数据。本申请实施例中，可以定义一个参考的时频资源，即上行参考资源(reference uplink resource，RUR)，用于第一指示信息通知停止发送上行数据的时频资源信息或者仅通知停止发送上行数据的时间信息。也可以定义一个参考的时域位置，用于第一指示信息仅通知停止发送上行数据的时间信息。
这里，第一指示信息可以为上行抢占指示(uplink preemption indication，UL PI)，UL PI可以用于指示该终端设备，其在哪些时频资源上停止上行数据的发送。下文将以参考的时频资源为上行参考资源为例进行说明。下文中可以将UL PI称为上行抢占通知或PI。另外，承载UL PI的时频资源集合在时域上可以占用一个或多个符号。
第三方面，提供了一种通信方法，包括：
获取第一指示信息，所述第一指示信息用于指示上行参考资源中的第一资源被占用，其中，所述上行参考资源的时域范围包括灵活符号和/或上行符号。
根据所述第一指示信息和所述上行参考资源的时域范围，确定所述第一资源的时域信息。
结合第三方面，在第三方面的某些可能的实现方式中，所述根据所述第一指示信息和所述上行参考资源的时域范围，确定所述第一资源的时域信息之前，还包括：获取第二指示信息，所述第二指示信息用于指示所述上行参考资源的时域范围。此时，网络设备可以显示地向终端设备指示上行参考资源的时域范围。具体的，第二指示信息可以承载在高层信令(例如无线资源控制RRC信令)或者物理层信令(例如DCI)。
第四方面，提供了一种通信方法，包括：
确定第一指示信息，所述第一指示信息用于指示上行参考资源中的第一资源被占用，其中，所述上行参考资源的时域范围包括灵活符号和/或上行符号。
发送所述第一指示信息。
结合第四方面，在第四方面的某些可能的实现方式中，还包括：发送第二指示信息，所述第二指示信息用于指示所述上行参考资源的时域范围。此时，网络设备可以显示地向终端设备指示上行参考资源的时域范围。具体的，第二指示信息可以承载在高层信令(例如无线资源控制RRC信令)或者物理层信令(例如DCI)。
这样，网络设备通过向终端设备发送第一指示信息来指示下行参考资源中的第一资源被占用，并且由于该上行参考资源的时域范围包括灵活符号和/或上行符号，即该上行参考资源的时域范围可以基于时隙格式进行确定，基于此网络设备可以向终端设备指示被抢占的上行资源，进而终端设备可以根据该第一指示信息停止在第一资源上发送数据，从而避免在该第一资源上对网络设备产生干扰。
其中，第一指示信息需要基于参考的时频资源或者参考的时域位置来指示时频资源或时域位置，结合第一指示信息的通知内容和参考的时频资源或者参考的时域位置可以得到停止当前上行数据的发送的时频资源或者停止当前上行数据的发送的时域位置。
第一指示信息可以指示被抢占资源的时频信息，或者只指示被抢占资源的时域信息，也可以只指示被抢占资源的频域信息。例如，当第一指示信息只通知时域信息时，如第一资源的起始位置，而不需要考虑该第一资源的频域信息。此时，收到该第一指示信息的终端设备需要在第一指示信息所指示的时域位置上停止当前上行数据的发送。
一种可能的实现方式中，第一指示信息可以为上行抢占指示(uplink preemption indication，UL PI)，UL PI可以用于指示该终端设备，其在哪些时频资源上停止上行数据的发送。下文将以参考的时频资源为上行参考资源为例进行说明。下文中可以将UL PI称为上行抢占通知或PI。另外，承载UL PI的时频资源集合在时域上可以占用一个或多个符号。
本申请实施例中，由于上行抢占通知是用于通知被抢占的终端设备停止在被其他终端设备占用的资源上发送上行数据，以避免该终端设备与其他终端设备在同一时间，使用相同的时频资源给网络设备发送上行数据，给网络设备造成严重的干扰，因此上行参考资源RUR的时域范围应当在该第一指示信息所在的时域位置之后。
可选的，可以根据发送第一指示信息的时域位置来确定上行参考资源的时域范围的起始位置。这里，第一指示信息的时域位置表示承载第一指示信息的资源集合占用的时域范围。
作为一例，可以以承载PI的时域位置的下一个符号为上行参考资源RUR的时域范围的起始位置。
作为另一例，可以根据第一指示信息所在的时域位置的最后一个符号的类型来确定RUR的起始位置。具体的，第一指示信息所在的时域位置的最后一个符号可以为上行符号或未知符号。
当该最后一个符号为上行符号时，该第一指示信息所在的时域位置可以都在下行区域。或者该第一指示信息的时域位置的第一个符号在灵活区域，且最后一个符号在下行区域，即该第一指示信息可以跨灵活区域和下行区域。当该最后一个符号为灵活符号时，该第一指示信息所在的时域位置可以都在灵活区域。或者，该第一指示信息的时域位置的第一个符号在下行区域，且最后一个符号在灵活区域，即该第一指示信息可以跨下行区域和灵活区域。
可选的，当所述第一指示信息的时域位置的结束位置在第一下行区域时，所述上行参考资源的时域范围的起始位置为与所述第一下行区域结束位置相邻的灵活符号或上行符号。
可选的，所述上行参考资源的时域范围的结束位置为第二下行区域起始位置相邻的灵活符号或上行符号，其中所述第二下行区域为所述第一下行区域之后的第一个下行区域。
可选的，当所述第一指示信息的时域位置的结束位置是灵活符号，即该第一指示信息的时域位置的结束位置在灵活区域时，所述上行参考资源的时域范围的起始位置为所述第一指示信息的时域位置之后与所述第一指示信息的时域位置相邻的符号。
可选的，所述上行参考资源的结束位置为第三下行区域的起始位置相邻的灵活符号或上行符号，其中，所述第三下行区域为所述第一指示信息的时域位置之后的第一个下行区域。
可选的，本申请实施例中，可以设置下行参考资源RUR的时域长度上限为n个符号，此时RUR的时域范围的结束位置最多为起始位置之后的n个符号。这里，n为正整数。作为一例，n的取值可以为12或者14。
或者，在另一个实施例中，上行参考资源的时域范围的时域长度可以为预设时域长度，该预设时域长度可以为一个固定的时域长度。此时，可以根据上行参考资源的时域范围的起始位置和该预设时域长度，确定该上行参考资源的时域范围。
可选的，所述第一指示信息包括k个比特，所述第一时域范围包括M个符号，
其中，当M大于第一阈值时，k＝k1；当M小于或等于所述第一阈值时，k＝k2，M，k，k1，k2分别为正整数，且k1大于或等于k2。
这样，当RUR长度过长时，可以避免造成指示精度过粗，当RUR长度过短时，避免造成比特位的浪费。

图2是本申请实施例提供的一种通信方法的示意性交互流程图。
210，网络设备向终端设备发送第一指示信息，所述第一指示信息用于指示终端设备停止当前上行数据的发送的时频资源或时域位置。
网络设备确定第一指示信息后，向终端设备发送该第一指示信息。
其中，第一指示信息需要基于参考的时频资源或者参考的时域位置来指示时频资源或时域位置，结合第一指示信息的通知内容和参考的时频资源或者参考的时域位置可以得到停止当前上行数据的发送的时频资源或者停止当前上行数据的发送的时域位置。
一种可能的实现方式中，参考的时频资源可以是上行参考资源(reference uplink resource，RUR)，则停止当前上行数据的发送的时频资源可以是上行参考资源中的第一资源。所述第一指示信息也可用于指示该上行参考资源中的第一资源被占用，或者所述第一指示信息指示的是第一资源的相对的时频位置。该上行参考资源的时域范围包括灵活符号和/或上行符号。
又一种可能的实现方式中，参考的时域位置可以是上行参考资源的时域位置，时域位置可以包括一个或多个符号，则停止当前上行数据的发送的时域位置可以是上行参考资源中的第一资源的时域位置，所述第一指示信息可以用于指示该上行参考资源中的第一资源被占用，或者所述第一指示信息指示的是第一资源的相对的时域位置。该上行参考资源的时域范围包括灵活符号和/或上行符号。
又一种可能的实现方式中，参考的时域位置也可以是时域上的一个符号，则停止当前上行数据的发送的时域位置可以基于参考的时域位置进行指示，例如给出一个偏移量，所述第一指示信息可以用于指示停止当前上行数据的发送的相对于参考的时域位置的时间长度。
具体的，终端设备可以获取来自网络设备发送的第一指示信息。这里，第一指示信息可以为上行抢占指示(uplink preemption indication，UL PI)，UL PI可以用于指示该终端设备，其在哪些时频资源上停止上行数据的发送。下文中可以将UL PI称为上行抢占通知或PI。另外，承载UL PI的时频资源集合在时域上可以占用一个或多个符号。
应理解，第一指示信息可以指示被抢占资源的时频信息，或者只指示被抢占资源的时域信息，也可以只指示被抢占资源的频域信息。例如，当第一指示信息只通知时域信息时，如第一资源的起始位置，而不需要考虑该第一资源的频域信息。此时，收到该第一指示信 息的终端设备需要在第一指示信息所指示的时域位置上停止当前上行数据的发送。
还应理解，第一指示信息通知的时域信息还可以是被抢占的终端设备需要停止发送的时间，不需要和第一资源做绑定。终端设备根据第一指示信息指示的时间决定如何发送上行数据。例如，收到该第一指示信息的终端设备需要在第一指示信息所指示的时间点停止当前上行数据的发送。或者当终端设备在第一指示信息指示的时间点没有上行数据发送，但是在此时间点后的一定时间段内，有上行数据发送，则停止该上行数据发送的部分或者全部。这里停止发送的时间还可以是一个时间范围，终端设备在第一指示信息指示的这个时间范围内不发送上行数据。本申请实施例中，可以定义一个参考的时频资源，即上行参考资源(reference uplink resource，RUR)，用于第一指示信息通知停止发送上行数据的时频资源信息或者仅通知停止发送上行数据的时间信息。也可以定义一个参考的时域位置，用于第一指示信息仅通知停止发送上行数据的时间信息。
具体的，第一指示信息可以通过该上行参考资源或参考的时域位置来指示第一资源。在一种可能的实现方式中，当上行资源是上行参考资源RUR时，UL PI可以用于指示RUR中第一资源的被抢占。在另一种可能的实现方式中，上行资源是上行时域资源时，UL PI可以用于指示该上行时域资源中第一资源的被抢占的时域位置，终端设备在UL PI所指示的时域位置上停止传输上行数据。在另一种可能的实现方式中，UL PI主要用于指示在第一时间点停止传输上行数据，终端设备在UL PI所指示的第一时间点停止传输上行数据。需要说明的是，此处均为举例说明，本申请实施例并不限于此。
这里，第一资源可以为URLLC业务占用的资源，例如URLLC的数据和调度此URLLC数据的DCI占用的资源，也可以是多个URLLC的数据和对应DCI占用的资源。可以理解的是，第一资源也可以是URLLC占用的，且和某个或者某些eMBB业务已调度的上行资源重合的资源，此外，由于PI的指示粒度可能较粗，因此PI指示的资源中可能包含一部分没有被URLLC占用的资源，本申请实施例对如何选择资源来进行指示不做具体限制。传输eMBB业务的终端设备收到PI后，只需要根据PI的指示来确定自己需要在哪些资源上停止发送上行数据即可。此外，在通知第一资源时，可以是具体的时频信息，也可以仅仅是频域或者时域信息。
在本申请实施例中，如不特别说明，均以参考的时频资源为上行参考资源为例进行说明。可以理解的是，如果上行资源为上行时域资源，方法也同样适用。或者，如果第一指示信息仅通知需要停止发送的时间时，确定上行参考资源的时域范围的起始位置确定的方法也同样适用于确定通知停止发送的时间点的参考时域位置，或者，确定上行参考资源的时域范围的起始位置和结束位置确定的方法也同样适用于确定停止发送的时间点的起始位置和停止发送的时间点的结束位置的参考时域位置。
可选的，本申请实施例中，所述第一指示信息用于指示上行参考资源中的第一资源被占用，所述上行参考资源的时域范围包括灵活(flexible symbols)符号和/或上行符号。
应理解，这里资源占用的时域范围中可以包括一个或多个时域单元，时域单元可以包括一个或多个时域符号(symbol)，也可以包括一个或多个时隙(slot)，还可以包括一个或多个迷你时隙(mini-slot)，或者，包括一个或多个子帧(subframe)。其中，上述时域符号可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，也可以是单载波频分复用(single-carrier frequency-division multiplexing,SC-FDM)符号。应 理解，本申请实施例中，时域范围可以替换为时域区间或时域位置，并且，时域单元也可替换为时间单元。下文将以时域单元包括一个或多个时域符号为例进行描述，但本申请实施例并不限于此。
具体的，5G系统支持灵活的时隙结构，即在1个时隙可全部用于上行，或者下行，或有些符号用于上行，有些符号用于下行。在一些具体的实现方式中，可使用组公共物理下行控制信道(Group Common PDCCH)指示时隙结构，时隙结构也可理解为时隙格式(Slot Format)，或时隙格式相关信息(Slot format related information)。网络设备发送Group Common PDCCH，终端设备检测Group Common PDCCH获取在slot内哪些符号是上行符号，哪些符号是下行符号，哪些符号是灵活符号(flexible symbols)。或者，也可以通过终端设备专用的(specific)下行控制信息DCI通知时隙格式的配置。其中，灵活符号可以根据配置或者调度用于上行传输或者下行传输，例如，灵活符号可以根据配置或者调度改为上行符号或者下行符号。
如上所述，一个slot中一个符号的类型可以是DL、UL、flexible中的一种，时隙格式可以包括符号为DL、UL、flexible的各种可能的组合。图3是一个时隙格式的示例，D代表下行符号，X代表flexible符号，U代表上行符号。具体的，D部分包括至少一个下行符号，X部分包括至少一个flexible符号，U部分包括至少一个上行符号。
可选的，本申请实施例中，网络设备或者终端设备可以根据第一指示信息所在的时域位置来确定上行参考资源的时域范围，这里上行参考资源的时域范围包括起始位置和结束位置。
具体的，由于上行抢占通知是用于通知被抢占的终端设备停止在被其他终端设备占用的资源上发送上行数据，以避免该终端设备与其他终端设备在同一时间，使用相同的时频资源给网络设备发送上行数据，给网络设备造成严重的干扰，因此上行参考资源的时域范围应当在该第一指示信息所在的时域位置之后。
具体的，网络设备可以先确定发送PI的时域位置，然后根据PI的时域位置确定RUR的时域范围。或者，网络设备可以先确定RUR的时域范围，再确定发送PI的时域位置。然后，网络设备可以根据确定PI的时域位置和该PI对应的RUR，确定PI的具体内容，即确定该RUR中的哪些资源将被占用。
并且，终端设备在接收到网络设备发送的PI时，可以基于预配置的方式来确定RUR。具体的，终端设备可以根据PI的时域位置，确定该PI对应的RUR。进一步根据PI的具体内容，确定该RUR中的哪些资源将被占用。
在一种可能的实现方式中，可以根据发送第一指示信息的时域位置来确定上行参考资源的时域范围的起始位置。这里，第一指示信息的时域位置表示承载第一指示信息的资源集合占用的时域范围。若第一指示信息占用1个符号，则第一指示信息的时域位置为该占用符号在时域上的位置，若第一指示信息占用多个符号，则第一指示信息在时域上占用多个符号，第一指示信息的时域位置为起始位置对应的符号至结束位置对应的符号在时域上的位置。
具体的，网络设备可以通过控制资源集合(control resource set，CORESET)向终端设备发送下行控制信息DCI，该DCI中可以包括该PI。CORESET是用来发送下行控制信息DCI的一个资源集合，是网络设备配置给终端设备的。具体而言，网络设备会指定 CORESET的时域位置，频域位置，时域大小，频域大小和承载的DCI类型中的至少一个。通常，一个CORESET可以包括1-3个符号。
作为一例，可以以承载PI的时域位置的下一个符号为上行参考资源RUR的时域范围的起始位置。在使用该方式确定RUR的时域范围时，如果承载PI的符号的下一个符号为下行符号时，由于上行抢占不会发生在下行符号上，因此PI中对应于下行部分的指示比特就浪费了。
作为另一例，可以根据第一指示信息所在的时域位置的最后一个符号的类型来确定RUR的起始位置。具体的，第一指示信息所在的时域位置的最后一个符号可以为上行符号或灵活符号。
当该最后一个符号为上行符号时，该第一指示信息所在的时域位置可以都在下行区域。或者该第一指示信息的时域位置的第一个符号在灵活区域，且最后一个符号在下行区域，即该第一指示信息可以跨灵活区域和下行区域。此时，按照下文中的情况1确定RUR的起始位置。
当该最后一个符号为灵活符号时，该第一指示信息所在的时域位置可以都在灵活区域。或者，该第一指示信息的时域位置的第一个符号在下行区域，且最后一个符号在灵活区域，即该第一指示信息可以跨下行区域和灵活区域。此时，按照下文中的情况2确定RUR的起始位置。
应理解，本申请实施例中，当一个时域范围包括的符号都为下行符号时，可以称该时域范围为下行区域(例如图3中的D部分)，当一个时域范围包括的符号都为灵活符号时，可以称该时域范围为灵活区域(例如图3中的X部分)，当一个时域范围包括的符号类都为上行符号时，可以称该时域范围为上行区域(例如图3所示的U部分)。
也就是说，下行区域包括一个或多个连续的下行符号，其起始位置和结束位置分别为下行符号，且下行区域与灵活符号或上行符号相邻。换句话说，下行区域包括至少一个下行符号，并且下行区域相邻的前一个和后一个时域符号不是下行符号。
类似的，灵活区域包括一个或多个连续的灵活符号，其起始位置和结束位置分别为灵活符号，且灵活区域与下行符号或上行符号相邻。即灵活区域包括至少一个灵活符号，并且灵活区域相邻的前一个和后一个时域符号不是灵活符号。
类似的，上行区域包括一个或多个连续的上行符号，其起始位置和结束位置分别为上行符号，且上行区域与下行符号或灵活符号相邻。即上行区域包括至少一个上行符号，并且上行区域相邻的前一个和后一个时域符号不是上行符号。
情况1：
当所述第一指示信息的时域位置的最后一个符号在第一下行区域时，所述上行参考资源的时域范围的起始位置为与所述第一下行区域结束位置相邻的灵活符号或上行符号。具体的，与所述第一下行区域结束位置相邻的灵活符号或上行符号，即为与所述第一下行区域中的最后一个下行符号相邻的后一个符号，该后一个符号为灵活符号或上行符号。
例如，第一指示信息的时域位置的结束位置在第一下行区域的结束位置上，也就是第一指示信息的时域位置的结束位置为下行符号，且与之相邻的后一个符号为灵活符号或上行符号，则上行参考资源的时域范围的起始位置为与第一指示信息的时域位置相邻的后一个灵活符号或上行符号。
又例如，第一指示信息的时域位置的结束位置在第一下行区域的起始位置与结束位置之间的下行符号或者起始位置上，则上行参考资源的时域范围的起始位置为与第一下行区域的结束位置相邻的后一个灵活符号或上行符号。
对应的，此时，所述上行参考资源的时域范围的结束位置可以为第二下行区域的起始位置相邻的灵活符号或上行符号，其中所述第二下行区域为所述第一下行区域之后的第一个下行区域。具体的，与所述第二下行区域的起始位置相邻的灵活符号或上行符号，即为所述第二下行区域中的第一个下行符号相邻的前一个符号，该前一个符号为灵活符号或上行符号。
图4示出了本申请实施例提供的一种RUR的时域范围的示意图。这里，PI在图4中的第一个D部分(即D1部分)发送。具体的，此时D1部分则对应于上文中所述的第一下行区域，且PI的时域位置在该第一下行区域的起始位置与结束位置之间的下行符号上，此时RUR的时域范围的起始位置为D1部分之后的第一个灵活符号，结束位置为图4中的第二个D部分(D2部分，即第二下行区域)的起始位置相邻的上行符号。也就是说，此时该PI对应的RUR的时域范围为该PI所在的下行区域之后的X部分(即X1部分)以及与该X部分相邻的U部分(即U1部分)。
情况2：
当所述第一指示信息的时域位置的最后一个符号为灵活符号(即该第一指示信息的时域位置的结束位置在灵活区域)时，所述上行参考资源的时域范围的起始位置为所述第一指示信息的时域位置之后与所述第一指示信息的时域位置相邻的符号。
例如，第一指示信息的时域位置的结束位置在灵活区域的结束位置上，也就是第一指示信息的时域位置的结束位置为灵活符号，且与之相邻的后一个符号为上行符号，则上行参考资源的时域范围的起始位置为与第一指示信息的时域位置相邻的后一个上行符号。
又例如，第一指示信息的时域位置的结束位置在灵活区域的起始位置与结束位置之间的灵活符号或者起始位置上，则上行参考资源的时域范围的起始位置为与该起始位置与结束位置之间的灵活符号或者起始位置相邻的后一个灵活符号。
对应的，此时，所述上行参考资源的结束位置为第三下行区域的起始位置相邻的灵活符号或上行符号，其中，所述第三下行区域为所述第一指示信息的时域位置之后的第一个下行区域。具体的，与所述第三下行区域的起始位置相邻的灵活符号或上行符号，即为所述第三下行区域中的第一个下行符号相邻的前一个符号，该前一个符号为灵活符号或上行符号。
图5示出了本申请实施例提供的另一种RUR的时域范围的示意图。这里。PI在图5中的第一个X部分(即X3部分)发送。具体的，此时X3部分对应上文中所述的灵活区域，其PI的时域位置位于该灵活区域的起始位置与结束位置之间的灵活符号上，此时RUR的时域范围的起始位置为PI所在的灵活符号之后的第一个灵活符号，结束位置为图5中的第二个D部分(D5部分，即第三下行区域)的起始位置相邻的上行符号。也就是说，此时该PI对应的RUR的时域范围包括图5所示的时域范围中的第一个X部分(X3部分)中的PI之后部分、第一个U部分(U3部分)、第二个X部分(X4部分)和第二个U部分(即U4部分)。
可选的，本申请实施例中，可以设置下行参考资源RUR的时域长度上限为n个符号， 此时RUR的时域范围的结束位置最多为起始位置之后的n个符号。这里，n为正整数。作为一例，n的取值可以为12或者14。
具体而言，当按照上文所述的方法(如图4或图5所示的方法)确定的RUR长度超过某个阈值时，可以将RUR长度限制在时域长度上限之内。例如，当该阈值为12，且图4中的第一个X部分中的符号数与第一个U部分中符号数之和为15时，可以将图4中的PI对应的RUR的时域范围确定为以该第一个X部分的第一个符号为起始位置，时域长度为12个符号的时域区间。
或者，上行参考资源的时域范围的时域长度可以为预设时域长度，该预设时域长度可以为一个固定的时域长度。此时，可以根据上行参考资源的时域范围的起始位置和该预设时域长度，确定该上行参考资源的时域范围。
可选的，本申请实施例中，网络设备还可以向终端设备发送第二指示信息，所述第二指示信息用于指示所述上行参考资源的时域范围。
此时，网络设备可以显示地向终端设备指示上行参考资源的时域范围。具体的，第二指示信息可以承载在高层信令(例如无线资源控制RRC信令)或者物理层信令(例如DCI)。
进一步地，由于灵活区域(即X部分)中的第一个符号不可能是上行符号，因此当PI在下行区域中时，RUR的起始位置是该下行区域之后的第二个灵活符号或上行符号，当PI在未知区域中时，RUR的起始位置为承载该PI的时域位置之后的第二个符号。这里如果定义参考时域位置，该参考时域位置可以与上文中的RUR相同，为避免重复，这里不再赘述。
可选的，本申请实施例中，所述第一指示信息包括k个比特，所述第一时域范围包括M个符号，其中，当M大于第一阈值时，k＝k1；当M小于或等于所述第一阈值时，k＝k2，M，k，k1，k2分别为正整数，且k1大于或等于k2。
具体的，第一指示信息中的k个比特可以用于指示RUR中的哪些时频资源被占用，和/或哪些时频资源没有被占用，例如将RUR划分为k个子区域，和第一指示信息中的k个比特一一对应。比特值为0指示对应区域被占用，或者表示接收PI的终端设备需要在其中停止发送上行数据。比特值为1表示对应区域没有被占用，或者表示接收PI的终端设备不需要改变在其中发送上行数据的动作。当然，1和0的含义可以互换，本申请实施例对此不限定。本申请实施例对每个比特的指示粒度也不作限定。
但是，如果k为定值，则当RUR长度过长时，会造成指示精度过粗，当RUR长度过短时，会造成比特位的浪费。基于此，本申请实施例可以设置至少一个阈值，并根据该至少一个阈值来设置k的取值。
具体如表1所示，当RUR的符号的个数M大于第一阈值(对应范围1)时，k取值可以为k1，当M小于或等于第一阈值(对应范围2)时，k取值可以为k2，并且k1大于k2。
表1
RUR长度 PI bit数
范围1 K1
范围2 K2
例如，作为一例，RUR的时域长度的上限为14时。此时，当RUR的长度为8-14时，可以设置PI为14bit，当RUR的长度为1-7时，可以设置PI为7bit。则此时，PI中的每个比特位可以用于指示其对应的RUR中的一个符号是否被占用。
表2
RUR长度(符号) PI bit数
8-14 14
1-7 7
应理解，本申请实施中，对于单载波的情况，终端设备可以在一个载波上接收PI，则此时该PI用于指示该载波上的抢占情况，此时承载该PI的DCI可以只有一个PI域。对于多载波的情况，终端设备可以在多个载波上都有数据需要发送，则终端设备可以在一个载波上接收PI，该PI可以指示多个载波上的抢占情况，此时承载该PI的DCI中可以包括多个PI域，并且每个PI与对应一个载波上的抢占情况。
220，终端设备根据所述第一指示信息，确定停止当前上行数据的发送的时频资源或时域位置。
终端设备获取第一指示信息后，可以根据第一指示信息的位置确定参考的时频资源，例如上行参考资源，再根据上行参考资源以及第一指示信息中指示的时频资源确定第一资源，从而在第一资源上停止发送上行数据，进而避免在第一资源上对网络设备接收上行数据产生干扰。
终端设备也可以根据第一指示信息的位置确定参考的时域位置，例如上行参考资源的时域范围以及第一指示信息中指示的第一资源的信息，确定第一资源的时域信息，从而在第一资源的时域范围内停止发送上行数据，进而避免在第一资源上对网络设备接收上行数据产生干扰。
终端设备也可以根据第一指示信息的位置确定参考的时域位置，以及第一指示信息中指示的时域位置，确定停止发送上行数据的时域位置，进而避免对网络设备接收上行数据产生干扰。
图6示出了本申请实施例提供的一种时隙格式的示意图。具体的，网络设备在X部分发送了PI 61，该PI 61可以用于指示其对应的RUR的时域范围中的第一资源(即该X部分中的阴影部分所示)被抢占，此时，在该PI 61所指示的该第一资源上不可能再有下行控制信令。而原本在该第一资源对应的时域位置也可能配置有coreset来发送PI(例如PI 62)，此时终端设备不需要在该第一资源上对PI 62进行监测。
因此，本申请实施例网络设备通过向终端设备发送第一指示信息来指示下行参考资源中的第一资源被占用，并且由于该上行参考资源的时域范围包括灵活符号和/或上行符号，即该上行参考资源的时域范围可以基于时隙格式进行确定，基于此网络设备可以向终端设备指示被抢占的上行资源，进而终端设备可以根据该第一指示信息停止在第一资源上发送数据，从而避免在该第一资源上对网络设备产生干扰。
图7示出了本申请实施例提供的一种通信装置700的示意性框图。该通信装置700包括获取单元710和确定单元720。
获取单元710，用于获取第一指示信息，所述第一指示信息用于指示上行参考资源中 的第一资源被占用，其中，所述上行参考资源的时域范围包括灵活符号和/或上行符号。
确定单元720，用于根据所述第一指示信息和所述上行参考资源的时域范围，确定所述第一资源的时域信息。
因此，网络设备通过向终端设备发送第一指示信息来指示下行参考资源中的第一资源被占用，并且由于该上行参考资源的时域范围包括灵活符号和/或上行符号，即该上行参考资源的时域范围可以基于时隙格式进行确定，基于此网络设备可以向终端设备指示被抢占的上行资源，进而终端设备可以根据该第一指示信息停止在第一资源上发送数据，从而避免在该第一资源上对网络设备产生干扰。
可替换地，本申请实施例中，所述第一指示信息可以用于指示终端设备停止当前上行数据的发送的时频资源或时域位置。
其中，第一指示信息需要基于参考的时频资源或者参考的时域位置来指示时频资源或时域位置，结合第一指示信息的通知内容和参考的时频资源或者参考的时域位置可以得到停止当前上行数据的发送的时频资源或者停止当前上行数据的发送的时域位置。
一种可能的实现方式中，参考的时频资源可以是上行参考资源RUR，则停止当前上行数据的发送的时频资源可以是上行参考资源中的第一资源。所述第一指示信息也可用于指示该上行参考资源中的第一资源被占用，或者所述第一指示信息指示的是第一资源的相对的时频位置。该上行参考资源的时域范围包括灵活符号和/或上行符号。
又一种可能的实现方式中，参考的时域位置可以是上行参考资源的时域位置，时域位置可以包括一个或多个符号，则停止当前上行数据的发送的时域位置可以是上行参考资源中的第一资源的时域位置，所述第一指示信息可以用于指示该上行参考资源中的第一资源被占用，或者所述第一指示信息指示的是第一资源的相对的时域位置。该上行参考资源的时域范围包括灵活符号和/或上行符号。
又一种可能的实现方式中，参考的时域位置也可以是时域上的一个符号，则停止当前上行数据的发送的时域位置可以基于参考的时域位置进行指示，例如给出一个偏移量，所述第一指示信息可以用于指示停止当前上行数据的发送的相对于参考的时域位置的时间长度。
应理解，第一指示信息可以指示被抢占资源的时频信息，或者只指示被抢占资源的时域信息，也可以只指示被抢占资源的频域信息。例如，当第一指示信息只通知时域信息时，如第一资源的起始位置，而不需要考虑该第一资源的频域信息。此时，收到该第一指示信息的终端设备需要在第一指示信息所指示的时域位置上停止当前上行数据的发送。
还应理解，第一指示信息通知的时域信息还可以是被抢占的终端设备需要停止发送的时间，不需要和第一资源做绑定。终端设备根据第一指示信息指示的时间决定如何发送上行数据。例如，收到该第一指示信息的终端设备需要在第一指示信息所指示的时间点停止当前上行数据的发送。或者当终端设备在第一指示信息指示的时间点没有上行数据发送，但是在此时间点后的一定时间段内，有上行数据发送，则停止该上行数据发送的部分或者全部。这里停止发送的时间还可以是一个时间范围，终端设备在第一指示信息指示的这个时间范围内不发送上行数据。本申请实施例中，可以定义一个参考的时频资源，即上行参考资源(reference uplink resource，RUR)，用于第一指示信息通知停止发送上行数据的时频资源信息或者仅通知停止发送上行数据的时间信息。也可以定义一个参考的时域位置， 用于第一指示信息仅通知停止发送上行数据的时间信息。
可选的，当所述第一指示信息的时域位置的结束位置在第一下行区域时，所述上行参考资源的时域范围的起始位置为与所述第一下行区域结束位置相邻的灵活符号或上行符号。
可选的，所述上行参考资源的时域范围的结束位置为第二下行区域起始位置相邻的灵活符号或上行符号，其中所述第二下行区域为所述第一下行区域之后的第一个下行区域。
可选的，当所述第一指示信息的时域位置的结束位置是灵活符号时，所述上行参考资源的时域范围的起始位置为所述第一指示信息的时域位置之后与所述第一指示信息的时域位置相邻的符号。
可选的，所述上行参考资源的结束位置为第三下行区域的起始位置相邻的灵活符号或上行符号，其中，所述第三下行区域为所述第一指示信息的时域位置之后的第一个下行区域。
可选的，所述获取单元710还用于获取第二指示信息，所述第二指示信息用于指示所述上行参考资源的时域范围。
可选的，所述第一指示信息包括k个比特，所述第一时域范围包括M个符号，
其中，当M大于第一阈值时，k＝k1；当M小于或等于所述第一阈值时，k＝k2，M，k，k1，k2分别为正整数，且k1大于或等于k2。
因此，本申请实施例网络设备通过向终端设备发送第一指示信息来指示下行参考资源中的第一资源被占用，并且由于该上行参考资源的时域范围包括灵活符号和/或上行符号，即该上行参考资源的时域范围可以基于时隙格式进行确定，基于此网络设备可以向终端设备指示被抢占的上行资源，进而终端设备可以根据该第一指示信息停止在第一资源上发送数据，从而避免在该第一资源上对网络设备产生干扰。

发送单元920，用于发送所述第一指示信息。
因此，网络设备通过向终端设备发送第一指示信息来指示下行参考资源中的第一资源被占用，并且由于该上行参考资源的时域范围包括灵活符号和/或上行符号，即该上行参考资源的时域范围可以基于时隙格式进行确定，基于此网络设备可以向终端设备指示被抢占的上行资源，进而终端设备可以根据该第一指示信息停止在第一资源上发送数据，从而避免在该第一资源上对网络设备产生干扰。
可替换地，本申请实施例中，所述第一指示信息用于指示终端设备停止当前上行数据的发送的时频资源或时域位置。
其中，第一指示信息需要基于参考的时频资源或者参考的时域位置来指示时频资源或时域位置，结合第一指示信息的通知内容和参考的时频资源或者参考的时域位置可以得到停止当前上行数据的发送的时频资源或者停止当前上行数据的发送的时域位置。

又一种可能的实现方式中，参考的时域位置可以是上行参考资源的时域位置，时域位置可以包括一个或多个符号，则停止当前上行数据的发送的时域位置可以是上行参考资源中的第一资源的时域位置，所述第一指示信息可以用于指示该上行参考资源中的第一资源被占用，或者所述第一指示信息指示的是第一资源的相对的时域位置。该上行参考资源的时域范围包括灵活符号和/或上行符号。
又一种可能的实现方式中，参考的时域位置也可以是时域上的一个符号，则停止当前上行数据的发送的时域位置可以基于参考的时域位置进行指示，例如给出一个偏移量，所述第一指示信息可以用于指示停止当前上行数据的发送的相对于参考的时域位置的时间长度。
应理解，第一指示信息可以指示被抢占资源的时频信息，或者只指示被抢占资源的时域信息，也可以只指示被抢占资源的频域信息。例如，当第一指示信息只通知时域信息时，如第一资源的起始位置，而不需要考虑该第一资源的频域信息。此时，收到该第一指示信息的终端设备需要在第一指示信息所指示的时域位置上停止当前上行数据的发送。
还应理解，第一指示信息通知的时域信息还可以是被抢占的终端设备需要停止发送的时间，不需要和第一资源做绑定。终端设备根据第一指示信息指示的时间决定如何发送上行数据。例如，收到该第一指示信息的终端设备需要在第一指示信息所指示的时间点停止当前上行数据的发送。或者当终端设备在第一指示信息指示的时间点没有上行数据发送，但是在此时间点后的一定时间段内，有上行数据发送，则停止该上行数据发送的部分或者全部。这里停止发送的时间还可以是一个时间范围，终端设备在第一指示信息指示的这个时间范围内不发送上行数据。本申请实施例中，可以定义一个参考的时频资源，即上行参考资源(reference uplink resource，RUR)，用于第一指示信息通知停止发送上行数据的时频资源信息或者仅通知停止发送上行数据的时间信息。也可以定义一个参考的时域位置，用于第一指示信息仅通知停止发送上行数据的时间信息。
可选的，当所述第一指示信息的时域位置的结束位置在第一下行区域时，所述上行参 考资源的时域范围的起始位置为与所述第一下行区域结束位置相邻的灵活符号或上行符号。
可选的，所述上行参考资源的时域范围的结束位置为第二下行区域起始位置相邻的灵活符号或上行符号，其中所述第二下行区域为所述第一下行区域之后的第一个下行区域。
