背景技术
目前，网络中引入的低能力终端硬件成本低、待机时间长且终端数量大，并且传输带宽很小，例如：几个MHz，为了保证其待机时间，需要降低物理下行控制信道(Physical Downlink Control Channel，PDCCH)的检测。从网络侧的角度来看，在较小的带宽内为数量巨大的终端发送PDCCH，将会带来严重的PDCCH碰撞问题。
在当前的无线系统中，网络侧可以根据配置需要在带宽内为终端配置下行控制信道资源集合(control resource set，CORESET)，并在其内配置搜索空间；另外，可以通过配置较小的PDCCH监听周期，通过时域上更多的传输机会降低不同终端PDCCH碰撞的几率。但是为了降低下行控制信道的碰撞概率，网络侧一般需要通过如下两种方式进行改善：其一是为终端配置较大的搜索空间，相应的需要较大的带宽；其二是为终端配置较为密集的时域监听位置，从而增加了终端侧的功耗。

步骤13：在所述PDCCH监听窗口内检测接收PDCCH。
具体的，基站配置PDCCH监听窗口的周期，终端在通过PDCCH监听窗口周期确定的时域范围内检测接收PDCCH。
本公开上述实施例中，根据接收的PDCCH监听窗口的相关参数，确定所述PDCCH监听窗口，并在所述PDCCH监听窗口内检测接收PDCCH，可以有效的降低在小带宽场景下的PDCCH碰撞概率，并降低终端的能量开销。

进一步的，在所述参数包括所述PDCCH监听窗口包含的时域单元的个数的情况下，所述步骤12具体可以包括：
根据搜索空间的监听时机MO所在的时域单元编号与所述PDCCH监听窗口包含的时域单元的个数的第一关联关系，确定所述PDCCH监听窗口包含的所有搜索空间监听时域位置。
可选的，所述第一关联关系可以为以下公式：
mod(n，W)＝i
其中，n为搜索空间的MO所在的时域单元编号，W为所述PDCCH监听窗口i包含的时域单元的个数，i为n除以W的商，且i为大于或等于0的整数；
所述PDCCH监听窗口i包含的搜索空间的MO为MO所在时隙编号满足公式的所有MO。
具体的，搜索空间的MO所在的时域单元编号为n，则满足上述公式的所有的MO均属于PDCCH监听窗口。其中，搜索空间监听时域位置称之为一个监听时机(monitoring occasion，MO)。例如：n为2，W为10，则i为0；n为5，W为10，则i为0；因此搜索空间的MO所在的时域单元编号为2和5的MO均属于一个PDCCH监听窗口；其中，PDCCH监听窗口编号可以根据i的取值定义(如：i为0的所有MO均属于PDCCH监听窗口#0，i为1的所有MO均属于PDCCH监听窗口#1)。
进一步的，所述PDCCH监听窗口包含的时域单元的个数为搜索空间监听周期的正整数倍。
例如：搜索空间(search space，SS)的监听周期为T，则W为N与T的乘积，其中N为大于或等于1的正整数。
进一步的，所述步骤11具体可以包括：
通过终端特定的无线资源控制RRC信令接收所述参数。
具体的，终端可以通过UE-specific的RRC信令接收基站配置的PDCCH监听窗口包含的时域单元的个数，使终端可以根据搜索空间的监听时机MO所在的时域单元编号与所述PDCCH监听窗口包含的时域单元的个数的第一关联 关系，确定PDCCH监听窗口的组成。
进一步的，在所述参数包括所述PDCCH监听窗口包含的时域单元的个数的情况下，所述步骤12具体可以包括：
根据时域单元编号和所述PDCCH监听窗口包含的时域单元的个数的第二关联关系，确定所述PDCCH监听窗口所包含的所有时域单元。
可选的，所述第二关联关系为以下公式：
mod(m，W)＝j
其中，m为时域单元编号，W为所述PDCCH监听窗口j包含的时域单元的个数，j为m除以W的商，且j为大于或等于0的整数；
所述PDCCH监听窗口j包含的时域单元为时域单元编号满足公式的所有时域单元，所述时域单元为连续多个时隙或者连续多个正交频分复用OFDM符号。
具体的，PDCCH监听窗口的组成可以根据时域单元的绝对编号进行划分，即满足上述公式的所有的时域单元均属于一个PDCCH监听窗口。例如：W为10，m为0～9时，j均为0，因此时域单元编号为0～9的所有时域单元均属于一个PDCCH监听窗口，j为PDCCH监听窗口的编号。
进一步的，所述步骤11具体可以包括：
通过终端特定的RRC信令或者小区特定的RRC信令接收所述参数。
具体的，终端可以通过高层信令接收基站配置的PDCCH监听窗口包含的时域单元的个数，使终端可以根据时域单元编号与所述PDCCH监听窗口包含的时域单元的个数的第二关联关系，确定PDCCH监听窗口的组成。其中，高层信令可以为UE-specific的RRC信令、cell-specific的RRC信令或者针对一组终端(多个终端)有效的信令。

具体的，搜索空间在每一个MO内的结构均相同，例如：一个搜索空间包含多个候选位置，每一个MO上均包含有多个候选位置；或者一个搜索空间分布在PDCCH监听窗口内的多个时域监听位置上(即一个搜索空间通过时分复 用的方式分布在所述PDCCH监听窗口内)。例如：一个搜索空间包含多个候选位置，一个候选位置分布在一个MO上。
进一步的，在所述PDCCH监听窗口包含的每一个MO内的搜索空间的结构相同的情况下，所述方法还可以包括：
在所述PDCCH监听窗口包含的任意MO上检测接收到期望的下行控制信息(Downlink Control Information，DCI)格式format之后，停止在所述PDCCH监听窗口包含的剩余MO上检测PDCCH。
具体的，终端在搜索空间的任何一个MO内检测接收到规定数量的期望DCI format后，停止在搜索空间的后续MO内检测PDCCH。
进一步的，在一个搜索空间分布在所述PDCCH监听窗口包含的多个MO上的情况下，所述方法还可以包括：
在所述搜索空间内的任意候选位置上检测接收到期望的DCI格式之后，停止在所述搜索空间内的剩余候选位置上检测PDCCH。
具体的，终端在任何P个候选位置PDCCH candidate上检测接收到期望的DCI format后，停止在搜索空间内的其他PDCCH candidate上检测PDCCH。其中，P为大于或等于1的正整数，由终端能力确定。
下面通过具体的实施例对上述方法进行详细说明(终端行为与基站行为的实施例是对应的)：
实施例一：
如图2所示，基站通过UE-specific的RRC信令为终端配置PDCCH监听窗口。假设基站为终端配置了搜索空间SS#1，且SS#1的监听周期为T个时隙slot，并且，基站还为该终端配置了PDCCH监听窗口包含的slot的个数，假设PDCCH监听窗口包含的slot的个数与SS#1的监听周期满足下述关系：
W＝N·T
在本实施例中，假设T＝10，N＝5，传输带宽为5MHz。
具体的，基站为终端配置的搜索空间监听时域位置偏移值为0，则终端在slot#0、slot#10、slot#2等slot上，在配置的搜索空间内检测接收PDCCH；其中，搜索空间监听时域位置称之为一个MO。每个PDCCH监听窗口可以通过如下方法确定：
如果搜索空间的MO所在的slot(也可称为该搜索空间监听所在的slot)编号为#n，则满足公式mod(n，W)＝i的所有MO均属于PDCCH监听窗口i。例如：W为50，slot为#0～#49任一个时，i均为0，则PDCCH监听窗口#0由slot#0～#49组成，则PDCCH监听窗口#0包含的PDCCH监听slot为{#0，#10，#20，#30，#40}；以此类推，PDCCH监听窗口#1包含的PDCCH监听slot为{#50，#60，#70，#80，#90}，PDCCH监听窗口#3包含的PDCCH监听slot为{#100，#110，#120，#130，#140}等。
终端在每个PDCCH监听窗口内按照配置的DCI format检测PDCCH，例如：基站为终端在搜索空间内配置的DCI format为某一个或者多个特定的DCI format，则终端在PDCCH监听窗口内按照配置的DCI format进行检测，如果终端在PDCCH监听窗口内的任意监听位置上检测接收到某个期望的DCI format，则终端在该PDCCH监听窗口内剩余的监听位置上不再按照该DCI format进行PDCCH的检测，即：如果终端在PDCCH监听窗口内检测接收到某个期望的DCI format，则终端在该PDCCH监听窗口内后续的监听位置上不再按照该DCI format进行PDCCH的检测。其中，PDCCH监听窗口的相关参数是根据每个搜索空间进行配置的。
实施例二：
如图3所示，基站为终端配置PDCCH监听窗口的长度(由W个slot组成)，W为大于或等于1的正整数。在本实施例中，假设W＝10，传输带宽为5MHz，每个PDCCH监听窗口所包含的slot通过如下方法确定：
满足mod(m，W)＝j的所有slot组成PDCCH监听窗口j，终端在一个PDCCH监听窗口内的任意一个slot上的任意搜索空间内检测接收到对应的期望DCI后，跳过窗口内剩余slot上该搜索空间的检测。
假设基站为终端配置了搜索空间SS#1和SS#2，且SS#1的监听周期为2个slot，SS#2的监听周期为5个slot，并假设SS#1和SS#2的时域偏移值均为0，则SS#1的监听slot编号为{#0，#2，#4，#6…}，SS#2的监听slot编号为{#0，#5，#10，#15…}，PDCCH监听窗口的示意图如图3所示。
终端在一个PDCCH监听窗口内的每个搜索空间内检测接收PDCCH，如果终端在PDCCH监听窗口内的某个搜索空间内检测接收到期望的DCI format， 则终端在该PDCCH监听窗口内的后续slot上不再该搜索空间。例如终端在slot#0上的SS#1内检测接收到对应的期望的DCI format，则在该PDCCH监听窗口内的后续监听位置上不再监听SS#1；终端在slot#0的SS#2内没有检测接收到对应的期望的DCI format，则在该PDCCH监听窗口内的后续位置上继续监听SS#2。其中，所述监听窗口通过cell-specific的RRC信令或者UE-specific的RRC信令进行配置。其中，基站也可以为终端仅配置一个搜索空间，在此不做限定。
实施例三：
基站为终端配置所述PDCCH监听窗口包含的监听时机MO的个数，通过MO的个数来确定PDCCH监听窗口，其中，PDCCH监听窗口的相关参数是根据每个搜索空间进行配置的。例如：基站为终端配置了搜索空间SS#1，其监听周期为10个slot，且时域偏移值为0，则终端在slot#0、slot#10、slot#20等slot上，在配置的搜索空间内监听PDCCH。所述PDCCH监听窗口包含5个MO，则所述第一个所述PDCCH监听窗口包含的MO位置为slot#0、slot#10、slot#20、slot#30和slot#40，并以此类推。
实施例四：
基站为所述PDCCH监听窗口配置监听周期，终端只在PDCCH监听窗口周期确定的PDCCH监听窗口内检测接收PDCCH。例如：PDCCH监听窗口的监听周期为40个slot，且其时域偏移值为0个slot，则终端只在PDCCH监听窗口起始slot编号满足mod(n，40)＝0的PDCCH监听窗口内检测接收PDCCH。其中，PDCCH监听窗口偏移值可以为大于0的任意整数，具体作用与当前搜索空间的偏移值类似，在此不再赘述。
本公开上述实施例中，根据接收的PDCCH监听窗口的相关参数，确定所述PDCCH监听窗口，并在所述PDCCH监听窗口内检测接收PDCCH，并且在所述PDCCH监听窗口包含的任意MO上检测接收到期望的DCI format之后，停止在所述PDCCH监听窗口包含的剩余MO上检测PDCCH，或者在所述搜索空间内的任意候选位置上检测接收到期望的DCI格式之后，停止在所述搜索空间内的剩余候选位置上检测PDCCH，可以有效的降低在小带宽场景下的PDCCH碰撞概率，并降低终端的能量开销。
如图4所示，本公开实施例还提供了一种物理下行控制信道的发送方法，应用于基站，包括：

步骤43，在所述PDCCH监听窗口内发送PDCCH。
具体的，基站配置PDCCH监听窗口的周期，基站在通过PDCCH监听窗口周期确定的时域范围内发送PDCCH。
本公开上述实施例中，根据配置的PDCCH监听窗口的相关参数，确定所述PDCCH监听窗口，并在所述PDCCH监听窗口内发送PDCCH，使终端在所述PDCCH监听窗口内检测接收PDCCH，可以有效的降低在小带宽场景下的PDCCH碰撞概率，并降低终端的能量开销。

具体的，基站通过UE-specific的RRC信令配置所述PDCCH监听窗口包含的MO的个数，基站根据MO的个数确定所述PDCCH监听窗口的组成。
进一步的在所述参数包括所述PDCCH监听窗口包含的时域单元的个数的情况下，所述步骤42具体可以包括：
根据搜索空间的监听时机MO所在的时域单元编号与所述PDCCH监听窗口包含的时域单元的个数的第一关联关系，确定所述PDCCH监听窗口包含的所有搜索空间监听时域位置。
可选的，所述第一关联关系为以下公式：
mod(n，W)＝i
其中，n为搜索空间的MO所在的时域单元编号，W为所述PDCCH监听窗口i包含的时域单元的个数，i为n除以W的商，且i为大于或等于0的整数；
所述PDCCH监听窗口i包含的搜索空间的MO为MO所在时隙编号满足公式的所有MO。
具体的，搜索空间的MO所在的时域单元编号为n，则满足上述公式的所有的MO均属于PDCCH监听窗口。其中，搜索空间监听时域位置称之为一个监听时机(monitoring occasion，MO)。例如：n为2，W为10，则i为0；n为5，W为10，则i为0；因此搜索空间的MO所在的时域单元编号为2和5的MO均属于一个PDCCH监听窗口；其中，PDCCH监听窗口编号可以根据i的取值定义(如：i为0的所有MO均属于PDCCH监听窗口#0，i为1的所有MO均属于PDCCH监听窗口#1)。
进一步的，所述PDCCH监听窗口包含的时域单元的个数为搜索空间监听周期的正整数倍。
例如：搜索空间(search space，SS)的监听周期为T，则W为N与T的乘积，其中N为大于或等于1的正整数。
进一步的，所述步骤41具体可以包括：
通过终端特定的无线资源控制RRC信令发送所述参数。
具体的，基站可以通过UE-specific的RRC信令配置PDCCH监听窗口包含的时域单元的个数，使终端和基站均可以根据搜索空间的监听时机MO所在的时域单元编号与所述PDCCH监听窗口包含的时域单元的个数的第一关联关系，确定PDCCH监听窗口的组成。
进一步的，在所述参数包括所述PDCCH监听窗口包含的时域单元的个数的情况下，所述步骤42具体可以包括：
根据时域单元编号和所述PDCCH监听窗口包含的时域单元的个数的第二关联关系，确定所述PDCCH监听窗口所包含的所有时域单元。
可选的，所述第二关联关系可以为以下公式：
mod(m，W)＝j
其中，m为时域单元编号，W为所述PDCCH监听窗口j包含的时域单元的个数，j为m除以W的商，且j为大于或等于0的整数；
所述PDCCH监听窗口j包含的时域单元为时域单元编号满足公式的所有时域单元，所述时域单元为连续多个时隙或者连续多个正交频分复用OFDM符号。
具体的，PDCCH监听窗口的组成可以根据时域单元的绝对编号进行划分，即满足上述公式的所有的时域单元均属于一个PDCCH监听窗口。例如：W为10，m为0～9时，j均为0，因此时域单元编号为0～9的所有时域单元均属于一个PDCCH监听窗口，j为PDCCH监听窗口的编号。
进一步的，所述步骤41具体可以包括：
通过终端特定的RRC信令或者小区特定的RRC信令接收所述参数。
