交叉引用

技术领域
本申请涉及通信领域，尤其涉及一种物理下行控制信道的监听方法、装置和设备。
背景技术
在移动通信系统中，当用户设备(User Equipment，UE，也可称为终端设备、终端等)被配置有不止一个搜索空间(Search Space，SS)集(set)时，由于每个SS set的监听时机(monitoring occasion)都是独立配置的，候选物理下行控制信道(Physical Downlink Control Channelcandidates，PDCCH candidates)或控制信道元素(Control Channel Element，CCE)的数量在时隙(slot)之间变化。因此，允许网络侧设备(比如基站)为UE配置每个时隙的或每个监听跨度(span)的候选PDCCH或CCE的数量超过UE的能力限制，即超额限定(overbooking)。对于每个时隙或每个监听跨度，UE和网络侧设备需要约定特定的SS set映射规则，根据该映射规则来确定SS set优先级大小并按照SS set优先级来映射每个时隙或每个监听跨度中的候选PDCCH和CCE。
但是，上述现有SS set映射规则，并不适用于PDCCH重复传输的场景，且并不适用于大于1个时隙或1个监听跨度下的候选PDCCH监听。

参见图2所示，本申请实施例提供一种物理下行控制信道的监听方法，由终端设备执行，该方法包括以下流程步骤：
步骤201：根据第一映射规则，监听第一时间间隔内的候选物理下行控制信道PDCCH，所述第一时间间隔包括K个时隙或K个监听跨度，K为大于或等于1的整数；其中，所述第一映射规则用于指示以下至少一项：第一搜索空间集合SS set在所述第一时间间隔内的映射优先级；在PDCCH监听 时机上N个控制资源集CORESET发生资源重叠时的CORESET监听规则，其中，N为大于1的整数；所述候选PDCCH跨时隙或跨监听跨度的映射规则。

进一步可选的，在上述第一搜索空间集合(Search Spaceset，SS set)为带宽部分(Bandwidth Part，BWP)上的SS set的情况下，可以理解为，该第一SS set为小区的BWP上的部分或全部SS set，其中，上述第一SS set的数量可以有一个或多个。也就是说，针对不同的小区的不同的BWP，第一SS set可以是不同的一个或多个SS set，还可以是相同的一个或多个SS set。
进一步可选的，在上述第一SS set为BWP上的搜索空间组中的SS set的情况下，可以理解为，上述第一映射规则用于指示搜索空间组中的第一SS set在所述第一时间间隔内的映射优先级。在一个示例中，该第一映射规则用于指示BWP的第一个SS group中全部SS set(即第一SS set)在该第一时间间隔内的映射优先级。

可选的，上述候选PDCCH的数量可以是一个或多个。
在本申请实施例中，终端设备可以根据第一映射规则监听K个时隙或K个监听跨度(即第一时间间隔)内的候选PDCCH。该第一映射规则规定了第一SS set在该第一时间间隔内的映射优先级。同时，该第一映射规则不仅适用于一个时隙或一个监听跨度上的SS set映射优先级的确定以及候选PDCCH的监听，还可以适用于多个时隙或多个监听跨度上SS set映射优先级的确定及候选PDCCH的监听。具体地，该第一映射规则可以用于指示以下至少一项：第一SS set在上述第一时间间隔内的映射优先级；在PDCCH监听时机上多个(即N个)CORESET发生资源重叠时的CORESET监听规则；所述候选PDCCH跨时隙或跨监听跨度的映射规则。本申请实施例，给出一种能够适用于大于或等于1个时隙或监听跨度内的SS set映射规则(或超前限定规则)，以能够适用于大于1个时隙或1个监听跨度上的候选PDCCH监听，并可以在第一SS set中包含至少一个承载有重复PDCCH的SS set时，能够适用于PDCCH重复传输的场景。同时，该实施例还可以给出多个CORESET资源冲突时，适用的CORESET的监听规则。

在本申请实施例中，终端设备在根据上述第一映射规则检测(或监听)第一时间间隔内的候选PDCCH之前，可以预先上报其自身是否支持该第一映射规则，以使网络侧设备可以根据终端设备上报的具体情况进行SS set的配置。在一个示例中，若终端设备上报其自身在所述第一时间间隔内支持上述第一映射规则，则网络侧设备可以根据上报的内容根据第一映射规则配置SS set，进一步使得终端设备可以根据该第一映射规则来检测该第一时间间隔内的候选PDCCH。
可选地，上述指示信息用于指示是否支持当所述第一时间间隔为大于或等于两个时隙或两个监听跨度时的所述第一映射规则。

(2)所述第一SS set的索引值。也就是说，SS set的映射优先级可以根据SS set的索引值大小来确定。在一个示例中，可以是SS set的索引值越大，SS set的映射优先级越低。在另一个示例中，可以是SS set的索引值越小，SS set的映射优先级越低。
(3)所述第一SS set的重复次数。也就是说，SS set的映射优先级可以根据SS set的重复次数来确定。在一个示例中，可以是SS set的重复次数越大，SS set的映射优先级越高。

可选地，该第一SS set的重复次数与所述第一SS set的索引值之间可以存在一定的映射关系，具体地，若该第一SS set的重复次数越大，则该第一SS set的索引值越大；或者，若该第一SS set的重复次数越小，该第一SS set的索引值越大。进一步可选的，若该第一SS set中的多个SS set的重复次数相同，则该多个重复次数相同的SS set的索引值的映射顺序可以随机。

可选地，当SS set的映射优先级由上述条件(1)，(2)，(3)，(4)，(5)，(6)中的多个条件来确定时，条件(1)，(2)，(3)，(4)，(5)，(6)之间也可以存在优先级高低排序，例如，这些条件的优先级高低可以是(1)＞(2)＞(3)＞(4)＞(5)＞(6)，也可以是其他优先级顺序，在此不做具体限定。
在一个示例中，所述第一SS set在所述第一时间间隔内的映射优先级，由所述第一SS set的类型、所述第一SS set的索引值和所述第一SS set的重复次数多个映射条件来确定。此时，多个映射条件分别可以是：约定SS set的类型中CSS set的映射优先级高于USS set的映射优先级；约定SS set的索引值越小该SS set的映射优先级越高；约定SS set的重复次数越大该SS set的映射优先级越高。且上述多个映射条件间的优先级排序为：(1)＞(3)＞(2)。现有如下SS set：USS set1，重复次数2；USS set2，重复次数3；USS set3重复次数2；CSS set1，重复次数为2；CSS set2，重复次数为1。则按照 上述三个条件来唯一的确定SS set优先级顺序为：CSS set1>CSS set2>USS set2>USS set1>USS set3。
在另一个示例中，所述第一SS set在所述第一时间间隔内的映射优先级，由所述第一SS set的类型、所述第一SS set的索引值和所述第一SS set的已完成重复次数多个映射条件来确定。此时，多个映射条件分别可以是约定SS set的类型中CSS set的映射优先级高于USS set的映射优先级；约定SS set的索引值越小该SS set优先级越高；约定SS set的已完成重复次数越大优先级越低。且(1)＞(4)＞(2)。现有如下SS set：USS set1，已完成重复次数2；USS set2，已完成重复次数3；USS set3已完成重复次数2；CSS set1，已完成重复次数为2；CSS set2，已完成重复次数为1。则按照上述三个条件来唯一的确定SS set优先级顺序为：CSS set2>CSS set1>USS set1>USS set2>USS set2。
在又一个示例中，所述第一SS set在所述第一时间间隔内的映射优先级，由所述第一SS set的类型、所述第一SS set的索引值、所述第一SS set的重复次数和所述第一SS set的已完成重复次数多个映射条件来确定。此时，多个映射条件分别可以是约定SS set的类型中CSS set的映射优先级高于USS set的映射优先级；约定SS set的索引值越小该SS set优先级越高；约定SS set的重复次数和已完成重复次数越大优先级越高。且(1)＞(3)＞(4)＞(2)。现有如下SS set：USS set1，重复次数3，已完成重复次数2；USS set2，重复次数3，已完成重复次数3；USS set3，重复次数2，已完成重复次数2；CSS set1，重复次数4，已完成重复次数为2；CSS set2，重复次数3，已完成重复次数为1。则按照上述三个条件来唯一的确定SS set优先级顺序为：CSS set1>CSS set2>USS set2>USS set1>USS set3。
可以理解，在确定第一SS set在第一时间间隔内的映射优先级时，至少考虑所述第一SS set的重复次数和/或所述第一SS set的已完成重复次数，可以使指示上述映射优先级的映射规则即第一映射规则适用于PDCCH重复传 输(PDCCH增强)的场景。
需要说明的是，本申请实施例中的协议约定可以指预先约定、预先定义或预先规定。
可选地，在本申请实施例的PDCCH的监听方法中，还可以包括以下内容之一：
(1)根据所述第一SS set在所述K个时隙中的前M个时隙内的已完成重复次数，调整所述第一SS set在所述K个时隙中的第M+1个时隙上的映射优先级。
(2)根据所述第一SS set在所述K个监听跨度中的前M个监听跨度内的已完成重复次数，调整所述第一SS set在所述K个监听跨度中的第M+1个监听跨度上的映射优先级。
在本申请实施例中，根据上述第一映射规则监听K个时隙或K个监听跨度内的候选PDCCH的过程中，可以根据该K个时隙的前M个时隙或K个监听跨度中M个监听跨度内SS set的已完成重复次数，动态调整该K个时隙中后续时隙或K个监听跨度中监听跨度上的映射优先级，比如第M+1个时隙或M+1监听跨度上的映射优先级。也就是说，在该在第一时间间隔包括多个时隙或多个监听跨度时，可以实现对该第一时间间隔中部分时隙或监听跨度上的映射优先级动态调整。
其中，上述M为小于K的整数，上述M+1为小于或等于K的整数。
可选地，在本申请实施例的PDCCH的监听方法中，上述CORESET监听规则，包括：

下面结合具体示例对本申请实施例的适用于PDCCH repetition方案的overbooking规则(即映射规则)进行说明。
在一个具体示例中，协议约定映射优先级条件为：(I)CSS set的映射优先级高于USS set；(II)SS setindex越小的映射优先级越高；(III)包括上述重复传输的PDCCH candidate的重复次数越高的SS set优先级越高。
可选地，网络配置CSS set 2中AL＝4的PDCCHcandidate进行重复传输，且重复次数为2；CSS set 1中未配置PDCCHcandidate的重复传输；USS set1中全部PDCCHcandidate进行重复传输，且重复次数为3；USS set3中DCI format 1-1和DCI format 0-1进行重复传输，重复次数为3。USS set2中没有配置PDCCHcandidate的重复传输。且K＝1，第一时间间隔为1个时隙。
按照本申请实施例中的映射规则，UE在一个时隙内检测搜索空间集的顺序为：
Option 1：CSS set2>CSS set1>USS set 1>USS set3>USS set2(采用条件I、II、III)；
Option 2：CSS set1>CSS set2>USS set 1>USS set2>USS set3(采用条件I、II)；
Option 3：USS set 1>USS set3>CSS set2>CSS set1>USS set2(采用条件III)。
在另一个具体示例中，协议约定映射优先级条件为：(i)CSS set的映射优先级高于USS set；(ii)SS setindex越小的映射优先级越高；(iii)包括上述重复传输的PDCCH candidate的重复次数越高的SS set优先级越高；(iv)已检测的SS set次数。
可选地，根据当前时隙或监听跨度之前已检测的SS set次数，来判断当前SS set的优先级。例如，网络配置USS set1中全部PDCCHcandidate进行重复传输，且重复次数为3，分别在3个时隙上重复。该USS set1在传输的第一个时隙内优先级按照上述条件i、ii、iii来确定，在下一个重复传输的时隙内该USS set1的优先级往后移动一位(降低)或往前移动一位(升高)，直到该USS set1的优先级被降到最低或升到最高，或已经完成全部3次传输 为止。
参见图3所示，本申请实施例提供一种物理下行控制信道的监听方法，由通网络侧设备执行，该方法包括以下流程步骤：

可选地，在上述第一SS set为BWP上的搜索空间组中的SS set的情况下，可以理解为，上述第一映射规则用于指示搜索空间组中的第一SS set在所述第一时间间隔内的映射优先级。在一个示例中，该第一映射规则用于指示BWP的第一个SS group中全部SS set(即第一SS set)在该第一时间间隔内的映射优先级。

可选地，上述候选PDCCH的数量可以是一个或多个。
在本申请实施例中，网络侧设备可以根据第一映射规则在K个时隙或K个监听跨度(即第一时间间隔)内传输候选PDCCH。该第一映射规则规定了第一SS set在该第一时间间隔内的映射优先级。同时，该第一映射规则不仅适用于一个时隙或一个监听跨度上的SS set映射优先级的确定以及候选PDCCH的监听，还可以适用于多个时隙或多个监听跨度上SS set映射优先级的确定及候选PDCCH的监听。具体地，该第一映射规则可以用于指示以下至少一项：第一SS set在上述第一时间间隔内的映射优先级；在PDCCH监听时机上多个(即N个)CORESET发生资源重叠时的CORESET监听规则；所述候选PDCCH跨时隙或跨监听跨度的映射规则。本申请实施例，给出一种能够适用于大于或等于1个时隙或1个监听跨度内的SS set映射规则(或超前限定规则)，以能够适用于大于1个时隙或1个监听跨度上的候选PDCCH监听，并可以在第一SS set中包含至少一个承载有重复PDCCH的SS set时，能够适用于PDCCH重复传输的场景。同时，该实施例还可以给出多个CORESET资源冲突时，适用的CORESET的监听规则。

需要说明的是，每个候选PDCCH由其对应的一个SS set来进行承载。在每一个上述第一时间间隔内的候选PDCCH可以是不同的或相同的候选PDCCH。进一步可选的，因此，在不同的第一时间间隔内，候选PDCCH可 能包含重复的PDCCH，也可能不包含重复的PDCCH。进一步可选的，在上述第一时间间隔内的候选PDCCH中包含重复的候选PDCCH的情况下，该重复的候选PDCCH可以指重复发送的或重复传输的候选PDCCH。如此，本申请实施例在监听候选PDCCH时，至少考虑到了PDCCH重复传输场景对SS set映射优先级等带来的影响，以使得上述第一映射规则进一步适用于PDCCH重复传输的场景。
可选地，上述K的取值为所述小区的BWP的所有跨时隙或所有跨监听跨度内重复PDCCH的最大重复次数。
进一步可选的，上述重复的候选PDCCH所在的SS set包括但不限于终端专用搜索空间集USS set和/或第一类型的公共搜索空间集CSS set。其中，CSS set可以是Type 3 CSS set。

可选地，在本申请实施例的PDCCH的监听方法中，在所述第一映射规则指示第一SS set在所述第一时间间隔内的映射优先级时，该第一SS set在所述第一时间间隔内的映射优先级，由以下至少一项确定：

(2)所述第一SS set的索引值。也就是说，SS set的映射优先级可以根据SS set的索引值大小来确定。在一个示例中，可以是SS set的索引值越大，SS set的映射优先级越低。在另一个示例中，可以是SS set的索引值越小，SS set的映射优先级越低。
(3)所述第一SS set的重复次数。也就是说，SS set的映射优先级可以根据SS set的重复次数来确定。在一个示例中，可以是SS set的重复次数越大，SS set的映射优先级越高。
可选地，该第一SS set的重复次数在以不同单位重复的场景中可以对应不同的取值，包括但不限于以下几种情形：
(a)在所述第一SS set以SS set为单位进行重复的情况下，所述第一SS set的重复次数等于所述第一SS set的重复次数。也就是说，在所述第一SS set按照SS set进行重复的情况下，所述第一SS set的重复次数等于所述第一SS set的重复次数。
(b)在所述第一SS set以聚合等级(Aggregation Level，AL)为单位进行重复的情况下，所述第一SS set的重复次数为：所述第一SS set中配置的全部AL重复次数中最大的AL重复次数，或者所述第一SS set中配置的全部AL重复次数之和。也就是说，在所述第一SS set按照聚合等级AL进行重复的情况下，所述第一SS set的重复次数为：所述第一SS set中配置的全部AL的重复次数中最大的AL重复次数，或者所述第一SS set中配置的全部AL的重复次数之和。
(c)在所述第一SS set以下行控制信息格式DCI format为单位进行重复的情况下，所述第一SS set的重复次数为：所述第一SS set中配置的全部DCI format的重复次数中最大的DCI format重复次数，或者所述第一SS set中配 置的全部DCI format的重复次数之和。也就是说，在所述第一SS set按照DCI format进行重复的情况下，所述第一SS set的重复次数为：所述第一SS set中配置的全部DCI format重复次数中最大的DCI format重复次数，或者所述第一SS set中配置的全部DCI format重复次数之和。
可选地，该第一SS set的重复次数与所述第一SS set的索引值之间可以存在一定的映射关系，具体地，若该第一SS set的重复次数越大，则该第一SS set的索引值越大；或者，若该第一SS set的重复次数越小，该第一SS set的索引值越大。进一步可选的，若该第一SS set中的多个SS set的重复次数相同，则该多个重复次数相同的SS set的索引值的映射顺序可以随机。
(4)所述第一SS set的已完成重复次数。也就是说，SS set的映射优先级可以根据SS set的已完成重复次数来确定。在一个示例中，可以是SS set的已重复次数越多，SS set的映射优先级越低。
(5)网络侧设备配置，其中，所述第一SS set由特定无线网络临时标识RNTI加扰或包含特定下行控制信息格式DCI format。也就是说，可以通过网络侧配置的方式确定由特定的无线网络临时标识RNTI加扰或包含特定的下行控制信息格式DCI format的所述第一SS set的映射优先级。在一个示例中，当所述第一SS set由P-RNTI加扰时，可以由网络侧设备配置其映射优先级最低。
(6)协议约定，其中，所述第一SS set由特定无线网络临时标识RNTI加扰或包含特定下行控制信息格式DCI format。也就是说，可以由协议约定的方式确定由特定的RNTI加扰或包含特定的DCI format的所述第一SS set的映射优先级。在一个示例中，当所述第一SS set由P-RNTI加扰时，可以由协议约定其映射优先级最低。
可选地的，当SS set的映射优先级由上述条件(1)，(2)，(3)，(4)，(5)，(6)中的多个条件来确定时，条件(1)，(2)，(3)，(4)，(5)，(6)之间也可以存在优先级高低排序，例如，这些条件的优先级高低可以是(1)＞(2) ＞(3)＞(4)＞(5)＞(6)，可以是其他优先级顺序，在此不做具体限定。
在一个示例中，所述第一SS set在所述第一时间间隔内的映射优先级，由所述第一SS set的类型、所述第一SS set的索引值和所述第一SS set的重复次数多个映射条件来确定。此时，多个映射条件分别可以是：约定SS set的类型中CSS set的映射优先级高于USS set的映射优先级；约定SS set的索引值越小该SS set的映射优先级越高；约定SS set的重复次数越大该SS set的映射优先级越高。且上述多个映射条件间的优先级排序为：(1)＞(3)＞(2)。现有如下SS set：USS set1，重复次数2；USS set2，重复次数3；USS set3重复次数2；CSS set1，重复次数为2；CSS set2，重复次数为1。则按照上述三个条件来唯一的确定SS set优先级顺序为：CSS set1>CSS set2>USS set2>USS set1>USS set3。
在另一个示例中，所述第一SS set在所述第一时间间隔内的映射优先级，由所述第一SS set的类型、所述第一SS set的索引值和所述第一SS set的已完成重复次数多个映射条件来确定。此时，多个映射条件分别可以是约定SS set的类型中CSS set的映射优先级高于USS set的映射优先级；约定SS set的索引值越小该SS set优先级越高；约定SS set的已完成重复次数越大优先级越低。且(1)＞(4)＞(2)。现有如下SS set：USS set1，已完成重复次数2；USS set2，已完成重复次数3；USS set3已完成重复次数2；CSS set1，已完成重复次数为2；CSS set2，已完成重复次数为1。则按照上述三个条件来唯一的确定SS set优先级顺序为：CSS set2>CSS set1>USS set1>USS set2>USS set2。
在又一个示例中，所述第一SS set在所述第一时间间隔内的映射优先级，由所述第一SS set的类型、所述第一SS set的索引值、所述第一SS set的重复次数和所述第一SS set的已完成重复次数多个映射条件来确定。此时，多个映射条件分别可以是约定SS set的类型中CSS set的映射优先级高于USS set的映射优先级；约定SS set的索引值越小该SS set优先级越高；约定SS set 的重复次数和已完成重复次数越大优先级越高。且(1)＞(3)＞(4)＞(2)。现有如下SS set：USS set1，重复次数3，已完成重复次数2；USS set2，重复次数3，已完成重复次数3；USS set3，重复次数2，已完成重复次数2；CSS set1，重复次数4，已完成重复次数为2；CSS set2，重复次数3，已完成重复次数为1。则按照上述三个条件来唯一的确定SS set优先级顺序为：CSS set1>CSS set2>USS set2>USS set1>USS set3。
可以理解，在确定第一SS set在第一时间间隔内的映射优先级时，至少考虑所述第一SS set的重复次数和/或所述第一SS set的已完成重复次数，可以使指示上述映射优先级的映射规则即第一映射规则适用于PDCCH重复传输(PDCCH增强)的场景。
