应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。
目前，终端设备可以根据高层配置或协议约定在预定义的搜索空间内盲检测物理下行控制信道(physical harq indication channel，PDCCH)。其中，搜索空间可用于指示终端设备盲检测PDCCH的时域资源位置。网络设备向终端设备配置搜索空间后，终端设备可以在搜索空间对应的时域资源位置上盲检测PDCCH。
在新无线(new radio，NR)中，为了支持多种业务，引入了多套搜索空间配置，一个带宽部分(bandwidth part，BWP)内最多可以配置10个搜索空间。
网络设备向终端设备配置的搜索空间可以包括公共搜索空间和用户专属搜索空间。公共搜索空间中传输的数据主要包括系统信息、RAR、寻呼消息等消息，每个终端设备都需要盲检测公共搜索空间中的PDCCH。用户专属搜索空间时针对特定终端设备发送的，网络设备向不同终端设备配置的用户专属搜索空间可以不同。
为了简化终端设备的盲检测，网络设备向终端设备配置了半静态的搜索空间优先级，终端设备可以按照该半静态的搜索空间优先级进行盲检测。
具体地，搜索空间的设计准则如下：
(1)公共搜索空间集合的优先级高于用户专属搜索空间集合的优先级。如果在某个时隙内，既包括网络设备配置的公共搜索空间，又包括网络设备配置的用户专属搜索空间，则终端设备在这个时隙中进行盲检测时，优先盲检测公共搜索空间中的PDCCH，然后再检测用户专属搜索空间中的PDCCH。
(2)在用户专属搜索空间集合内，ID编号小的搜索空间的优先级高于ID编号大的搜索空间的优先级。网络设备可以向终端设备配置多套用户专属搜索空间，并对该多套专属搜索空间进行编号。终端设备在盲检测时，可以优先检测ID编号小的搜索空间中的PDCCH。
(3)如果配置的用户专属搜索空间的集合超过终端设备盲检测的能力，超出部分的专属搜索空间集合内的所有候选控制信道均不进行盲检测。且ID编号大于这个搜索空间集合的用户专属搜索空间集合也不进行盲检测。
例如，终端设备的检测能力为：一个时隙内的盲检测次数最大为15次。假设网络设备向终端设备配置的某个时隙内包括一个公共搜索空间和3个用户专属搜索空间，且每个搜索空间的盲检测次数为4次，则终端设备需要在这个时隙内进行16次的盲检测，这超出了终端设备的盲检测能力。因此，终端设备在该时隙内进行盲检测时，可以放弃ID编号最大的用户专属搜索空间的4次盲检测，而仅在该时隙进行12次的盲检测。
(4)网络设备需要确保公共搜索空间集合的盲检测的复杂度不超过终端设备的能力。
但是，上述设计准则存在以下问题：1)公共搜索空间优先级总是高于用户专属搜索空间，条件性发生的公共信令在终端设备没有传输时，会浪费终端盲检测机会；2)根据ID编号确定搜索用户专属搜索空间的优先级，使得用户专属搜索空间的优先级不能够适应业务需要动态调整。
下面以上行停止传输控制信息所在的搜索空间为例，对上述问题进行描述。
目前的5G系统引入了高可靠低时延通信(ultra reliable low latency communications，URLLC)业务，该业务的特征是在极端的时延内(例如，1ms)实现超高可靠性(例如，99.999％)的传输。为了实现这个目标，上行考虑引入抢占机制(preemption)，即在增强移动带宽(enhanced mobile broadband，eMBB)业务传输过程中，插入URLLC业务，如图2所示。
为了避免eMBB业务对URLLC业务的影响，网络设备可以向终端设备发送上行停止传输控制信息，以指示终端设备停止eMBB业务的传输。
终端设备只有在有上行传输时，盲检测上行停止传输控制信息才有意义，如果终端设备没有上行传输，终端设备就没有必要检测上行停止传输控制信息，但如果终端设备仍然去检测上行停止传输控制信息，这样会浪费终端设备的盲检测机会。
假设上行停止传输控制信息所在的搜索空间为公共搜索空间，且终端设备当前没有上行传输，由于公共搜索空间的优先级高于用户专属搜索空间的优先级，终端设备会优先检测公共搜索空间，即终端设备仍然会优先检测网络设备配置的用于发送上行停止传输控制信息的公共搜索空间，这样会浪费终端设备的盲检测机会，使得终端设备不能及时地检测到其他信息。
如果终端设备有上行传输，但由于半静态优先级的配置，导致终端设备不能及时检测到上行停止传输控制信息，从而影响其他业务的传输。
假设上行停止传输控制信息所在的搜索空间为用户专属搜索空间，用户专属搜索空间的优先级是根据ID编号大小进行确定的。假设终端设备当前有上行传输，终端设备需要接收上行停止传输控制信息以停止当前的上行传输，但是由于搜索空间的ID编号的限制，可能会导致终端设备不能及时地检测到上行停止传输控制信息，影响其他业务的传输。因此，根据ID编号确定的专属搜索空间的优先级，使得搜索空间的优先级不能够适应业务需要动态调整。
因此，本申请实施例提供了一种用于检测、发送PDCCH的方法，能够动态调整搜索空间的优先级，能够充分利用终端设备的盲检测机会。
图3是本申请实施例提供的一种用于检测、发送PDCCH的方法，该方法包括步骤S310～S330。
S310、终端设备根据第一信息，确定搜索空间的优先级。
或者，S310包括：网络设备根据第一信息，确定搜索空间的优先级。
该第一信息为网络设备向终端设备发送的信息，例如，该第一信息为网络设备向终端设备动态配置的信息。
该第一信息例如可为调度信息，网络设备可以根据业务的传输需求向终端设备发送调度信息，在不同的时刻，网络设备可以向终端设备发送不同业务的调度信息。
该第一信息又例如可以为时隙格式指示信息，网络设备可以根据终端设备的上下行传输需求，向终端设备发送不同的时隙格式指示信息。如在终端设备对下行传输的需求比较大时，向终端设备指示较多的下行时隙，在终端设备对上行传输的需求比较大时，向终端设备指示较多的上行时隙。
S320、终端设备基于该搜索空间的优先级，对PDCCH进行检测。
终端设备在检测PDCCH时，优先检测优先级高的搜索空间中的PDCCH，然后再检测 优先级低的搜索空间中的PDCCH。
S330、网络设备基于该搜索空间的优先级，发送PDCCH。
网络设备在发送PDCCH时，可以优先发送优先级高的搜索空间对应的PDCCH，然后再发送优先级低的搜索空间对应的PDCCH。
本申请实施例中的搜索空间的优先级不是静态的、或半静态的，而是会根据网络设备发送的第一信息动态调整，使得搜索空间的优先级能够适应业务需要动态调整，以满足不同业务的传输需求。同时，通过动态调整搜索空间的优先级，也能够充分利用终端设备的盲检测机会，能够避免终端设备做一些无意义的盲检测。
第一信息例如可以为调度信息，该调度信息例如可以为上行调度信息，终端设备可以根据上行调度情况，确定搜索空间的优先级。上行调度信息用于调度终端设备进行上行传输，终端设备可以根据有没有上行传输，对搜索空间进行不同的排序。
根据上文的描述，第一信息例如可以为调度eMBB业务的调度信息，或者第一信息例如可以为调度URLLC业务的调度信息。
第一信息例如还可以为子帧的上下行方向指示信息。第二信息为调度信息。如果终端设备被限定在特定的子帧格式下才能调度，则终端设备可以先基于上下行方向指示信息确定该子帧是否适合用户调度，对于不适合用户调度的子帧，则终端设备不在该子帧检测第二信息。
本申请实施例中的搜索空间可以包括第一搜索空间，该第一搜索空间用于传输第二信息，第一搜索空间用于传输第二信息可以表示第一搜索空间被终端设备用于在物理下行控制信道上检测第二信息。
本申请实施例对第二信息不做具体限定。对于终端设备来说，该第二信息可以是基于第一信息接收的。也就是说，该第二信息是条件性接收的信息，终端设备并不是在每个第二信息对应的搜索空间上都去接收第二信息。
该第二信息例如可以为上行停止传输控制信息，第一信息可以为调度信息，该调度信息用于指示终端设备进行上行传输。终端设备只有在有上行传输的情况下，才去接收上行停止传输控制信息；终端设备在没有上行传输的情况下，不接收上行停止传输控制信息。
该第二信息例如也可以为功率调整信息，第一信息为调度信息，该调度信息用于指示终端设备进行上行传输或下行传输。终端设备可以在有上行传输或下行传输的情况下，接收功率调整信息，而在内有上行传输或下行传输的情况下，不接收功率调整信息。
该第二信息例如也可以为调度第一业务的调度信息，该第一业务可以包括eMBB业务。第一信息可以为调度URLLC业务的调度信息。终端设备可以在有URLLC业务传输的情况下，不接收网络设备对eMBB业务的调度；终端设备在没有URLLC业务调度的情况下，接收网络设备对eMBB业务的调度。
举例说明，搜索空间1用于传输URLLC调度信息，搜索空间2用于传输eMBB调度信息。当终端设备在时隙1在搜索空间1上接收到网络设备对URLLC业务的调度信息，该调度信息用于指示终端设备在时隙5上进行URLLC业务的传输，则终端设备不在时隙1至时隙5之间的搜索空间2中的PDCCH进行检测。
搜索空间的优先级可以包括第一时间范围内的搜索空间的优先级，和/或第一时间范围之外的搜索空间的优先级，其中，第一时间范围是根据第一信息确定的。
假设第一信息为调度信息，该第一时间范围可以是调度信息调度终端设备进行上行传 输的时隙，或者该第一时间范围可以是终端设备接收到该调度信息的时隙至该调度信息指示终端设备进行上行传输的时隙之间的部分或全部的时隙。
下面结合图4进行描述。
终端设备在时隙n接收到网络设备发送的上行授权，该上行授权指示终端设备在时隙(n+m)进行上行传输，n为整数，m为正整数，则第一时间范围可以为时隙(n+m)对应的时间范围，或者第一时隙可以为时隙n至时隙(n+m)中的部分或全部的时隙对应的时间范围。也就是说，本申请实施例确定的搜索空间的优先级可以适用于时隙n，也可以适用于时隙n至时隙(n+m)中的部分或全部的时隙。
具体地，终端设备可以根据该上行授权，确定时隙(n+m)对应的搜索空间的优先级，或者终端设备可以根据该上行授权，确定时隙n至时隙(n+m)之间的部分或全部的时隙对应的搜索空间的优先级。
本申请实施例中的搜索空间可以包括公共搜索空间，或者，本申请实施例中的搜索空间可以包括公共搜索空间和用户搜索空间。即，本申请实施例可以对公共搜索空间和用户专属搜索空间进行排序，也可以仅对用户专属搜索空间进行排序。
如果第一搜索空间为公共搜索空间，则在第一时间范围之内，第一搜索空间的优先级高于用户传输搜索空间的优先级；在第一时间范围之外，第一搜索空间的优先级低于部分或全部的用户专属搜索空间。或者，在第一时间范围之外，第一搜索空间失效，终端设备可以不检测第一搜索空间。
例如，假设第一时间范围为时隙n至时隙(n+m)之间的时隙，则在时隙n至时隙(n+m)之间的时间范围内，终端设备优先检测第一搜索空间，然后再检测用户专属搜索空间，这样能够保证终端设备及时地接收到第一搜索空间中传输的信息；在时隙n至时隙(n+m)之外的时间范围，终端设备可以优先检测用户传输搜索空间，然后再检测第一搜索空间，或者终端设备不检测第一搜索空间。
举例说明，终端设备可以在确定搜索空间的优先级之前，可以接收网络设备发送的搜索空间的配置信息，该搜索空间的配置信息可以包括搜索空间的时域配置信息以及搜索空间的编号。终端设备接收网络设备发送的上行停止传输控制信息的配置信息，该上行停止传输控制信息的配置信息用于指示上行停止传输控制信息所在的搜索空间。终端设备可以在上行停止传输控制信息所在的搜索空间上检测上行停止传输控制信息。假设终端设备接收到N个用户专属搜索空间配置，其编号依次为{0,1,2,…N-1}，N为正整数，并获得上行停止传输控制信息所在的搜索空间的为公共搜索空间K。
终端设备基于上行传输情况，判定公共搜索空间K的优先级是否优于用户专属搜索空间。具体地，参考图4，终端设备在时隙n接收到网络设备发送的上行授权，该上行授权指示终端设备在时隙(n+m)进行上行传输，其对应的第一时间范围为时隙n～时隙(n+m)。
终端设备在时隙(n+x)上盲检测PDCCH时，x为正数，且x＜m，终端设备优先检测搜索空间K，然后依次检测用户专属搜索空间；终端设备在时隙(n+y)上盲检测PDCCH时，y为正数，且y＞m，则终端设备优先检测用户专属搜索空间部分或全部的搜索空间，然后再检测公共搜索空间K，或者终端设备不检测公共搜索空间K。
可以理解的是，终端设备在检测用户专属搜索空间时，仍可以按照传统的方式，根据ID编号的大小依次检测用户专属搜索空间。
类似地，网络设备确定搜索空间的优先级的方式可以与终端设备相同。例如，网络设 备可以根据是否向终端设备调度了上行传输，确定搜索空间的优先级。如果网络设备向终端设备调度了上行传输，则公共搜索空间K的优先级高于用户专属搜索空间，网络设备可以优先发送公共搜索空间K对应的PDCCH，然后再发送用户专属搜索空间对应的PDCCH；如果网络设备没有向终端设备调度上行传输，则公共搜索空间K的优先级低于用户专属搜索空间的优先级，终端设备可以优先发送用户专属搜索空间对应的PDCCH，然后再发送公共搜索空间K对应的PDCCH，或者公共搜索空间K失效，网络设备不发送公共搜索空间K对应的PDCCH，这样能够节省信令开销。
如果第一搜索空间为用户专属搜索空间，则在第一时间范围内，第一搜索空间的优先级高于部分或全部其他用户专属搜索空间的优先级；在第一时间范围以外，第一搜索空间的优先级低于部分或全部其他用户专属搜索空间的优先级，其中，其他用户专属搜索空间的优先级为用户专属搜索空间中除第一搜索空间之外的其他搜索空间。
例如，假设第一时间范围为时隙n至时隙(n+m)之间的时隙，则在时隙n至时隙(n+m)之间的时间范围内，终端设备优先检测第一搜索空间，然后再检测其他用户专属搜索空间，这样能够保证终端设备及时地接收到第一搜索空间中传输的信息；在时隙n至时隙(n+m)之外的时间范围，终端设备可以优先检测部分或全部的其他用户传输搜索空间，然后再检测第一搜索空间，或者终端设备不检测第一搜索空间。
举例说明，终端设备可以在确定搜索空间的优先级之前，可以接收网络设备发送的搜索空间的配置信息，该搜索空间的配置信息可以包括搜索空间的时域配置信息以及搜索空间的编号。终端设备接收网络设备发送的上行停止传输控制信息的配置信息，该上行停止传输控制信息的配置信息用于指示上行停止传输控制信息所在的搜索空间。终端设备可以在上行停止传输控制信息所在的搜索空间上检测上行停止传输控制信息。假设终端设备接收到N个用户专属搜索空间配置，其编号依次为{0,1,2,…N-1}，并获得上行停止传输控制信息所在的搜索空间的为用户专属搜索空间K，N为正整数，K为小于N的整数。
终端设备基于上行传输情况，判定用户专属搜索空间K的优先级是否优于其他用户专属搜索空间。具体地，参考图4，终端设备在时隙n接收到网络设备发送的上行授权，该上行授权指示终端设备在时隙(n+m)进行上行传输，其对应的第一时间范围为时隙n～时隙(n+m)。
终端设备在时隙(n+x)上盲检测PDCCH时，x为正数，如果x＜m，终端设备优先检测用户专属搜索空间K，然后依次检测用户专属搜索空间，即用户专属是搜索空间的优先级顺序为{K,0,1,...K-1,K+1,…,N-1}；如果x＞m，则终端设备优先检测用户专属搜索空间部分或全部的搜索空间，然后再检测公共搜索空间K，即用户专属是搜索空间的优先级顺序为{0,1,...K-1,K+1,…,N-1,K}，或者用户专属是搜索空间的优先级顺序为{0,1,...K-1,K,K+1,…,N-1}。终端设备在时隙(n+y)上盲检测PDCCH时，y为正数，且y＞m，终端设备也不检测公共搜索空间K，在该情况下，用户专属搜索空间的优先级顺序为{0,1,...K-1,K+1,…,N-1}。
需要说明的是，本申请实施例中的第一信息可以包括多个调度信息，在该情况下，第一时间范围为根据该多个调度信息确定的时间范围。例如，终端设备当前有3个上行调度，分别为上行调度1、上行调度2、上行调度3，终端设备根据上行调度1确定的时间范围为时间范围1，根据上行调度2确定的时间范围为时间范围2，根据上行调度3确定的时间范围为时间范围3，则第一时间范围为时间范围1、时间范围2、时间范围3的集合，终端 设备可以确定该集合内的搜索空间的优先级、和/或该集合之外的搜索空间的优先级。
终端设备根据每个调度信息确定时间范围的方式可以参见上文图4的描述，为了简洁，此处不再赘述。
