Description

确定搜索空间集配置的方法及装置、计算机可读存储介质
本申请要求于2020年5月15日提交中国专利局、申请号为202010413837.4、发明名称为“确定搜索空间集配置的方法及装置、计算机可读存储介质”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
本发明涉及无线通信技术领域，尤其涉及一种确定搜索空间集配置的方法及装置、计算机可读存储介质。
背景技术
随着通信技术的发展，未来的新空口(New Radio，NR)可以支持低复杂度的用户设备(User Equipment，UE)。低复杂度UE的成本较低，可以适用于机器类型通信(Machine Type Communication，MTC)或者物联网通信(Internet of Thing，IoT)。
相对于常规的UE，低复杂度的UE的带宽较小、天线数较少、能力较弱且UE处理时间放松。带宽较小意味着带宽从100MHz缩减为50MHz或20MHz或10MHz或5MHz。天线数减少意味着接收天线数从4根天线缩减为2根或1根天线。带宽缩减和天线数减少会引起覆盖缩小或者有效的小区半径缩小，这是因为：带宽缩减会导致物理下行控制信道(Physical Downlink Control Channel，PDCCH)的最大聚合等级(Aggregation Level，AL)减少，从而导致编码增益的减少，接收天线数减少会导致接收分集增益的减少。
因此，引入一些针对PDCCH覆盖恢复(Coverage Level)的机制。PDCCH覆盖恢复的机制包括增加控制资源集(Control Resource Set， CORESET)的持续时间，从而提高最大聚合等级；以及PDCCH重复发送，UE可以合并多个PDCCH来间接增加PDCCH时域资源。
在初始接入(Initial Access)过程中，UE监听主系统信息块(Master Information Block，MIB)配置的公共PDCCH，MIB配置的公共PDCCH对应的搜索空间集(search space set)一般称为search space set 0(因其标识为0)。由于低复杂度UE需要覆盖恢复，因此低复杂度UE的search space set 0需要对应不同的覆盖恢复配置。例如，当覆盖损失为3dB时，需要对应3dB的覆盖恢复的配置，当覆盖损失为6dB时，需要对应6dB的覆盖恢复的配置。
然而，低复杂度UE如何根据覆盖恢复需求以自适应的确定搜索空间集的配置，是一个亟需解决的问题。

附图说明

图2是本发明实施例中的一种确定搜索空间集配置的装置结构示意图。
具体实施方式
如前所述，低复杂度UE如何根据覆盖恢复需求以自适应的确定搜索空间集的配置，是一个亟需解决的问题。
在本发明实施例中，通过接收网络侧下发的信令，根据接收到的信令确定搜索空间集的配置，从而实现低复杂度的UE自适应地确定搜索空间集的配置。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
本发明实施例提供了一种确定搜索空间集配置的方法，参照图1，以下通过具体步骤进行详细说明。
在具体实施中，下述步骤S101～步骤S102所提供的确定搜索空间集配置的方法可以由用户设备中具有数据处理功能的芯片(如基带芯片)执行，或者由用户设备中包含有数据处理功能的芯片(如基带芯片)的芯片模组执行。
步骤S101，接收信令。
在具体实施中，UE可以接收网络侧下发的信令。网络侧下发的信令可以是MIB信令。
在本发明实施例中，UE可以为低复杂度UE。在实际应用中可知， 低复杂度的UE的带宽较小、天线数较少、能力较弱且UE处理时间放松。带宽较小意味着带宽从100MHz缩减为50MHz或20MHz或10MHz或5MHz。天线数减少意味着接收天线数从4根天线缩减为2根或1根天线。
步骤S102，根据所述信令，确定搜索空间集的配置。
在具体实施中，UE在接收到信令之后，可以根据接收到的信令，确定搜索空间集的配置。UE确定的搜索空间集的配置可以为搜索空间集的PDCCH重复次数。
在本发明实施例中，UE在确定搜索空间集的配置时，可以确定标识为0的搜索空间集的PDCCH配置，标识为0的搜索空间集即为search space set 0。一般来说，标识为0的搜索空间集(或搜索空间)为MIB配置的搜索空间集(或搜索空间)，或者为由PDCCH-ConfigSIB1配置的搜索空间集(或搜索空间)，或者为由SearchSpaceZero配置的搜索空间集(或搜索空间)。UE确定的标识为0的搜索空间集的PDCCH配置可以为：标识为0的搜索空间集的PDCCH重复次数。
在具体实施中，UE可以根据参数和/或信令，确定搜索空间集的PDCCH重复次数。参数和/或信令可以包括以下至少一种：覆盖恢复值；UE的带宽与接收天线数中的至少之一；控制资源集的带宽、控制资源集的持续时间以及UE的接收天线数；最大聚合等级和UE的接收天线数；UE的类型。UE的带宽，又可以称为UE支持的带宽、UE支持的最大带宽、UE的信道带宽、UE支持的信道带宽或UE支持的最大信道带宽。
UE可以通过信令获得控制资源集的带宽和控制资源集的持续时间，其中控制资源集可以为标识为0的控制资源集，简称为CORESET0。一般来说，标识为0的控制资源集为MIB配置的控制资源集，或者为由PDCCH-ConfigSIB1配置的控制资源集，或者为由ControlResourceSetZero配置的控制资源集。UE可以通过信令获得最 大聚合等级，其中最大聚合等级可以通过控制资源集的配置获得，控制资源集的配置包括控制资源集的带宽和控制资源集的持续时间。其中控制资源集可以为标识为0的控制资源集。UE可以通过UE的带宽与接收天线数中的至少之一获得UE的类型。
相应地，UE也可以采用上述参数和/或信令确定标识为0的搜索空间集的PDCCH重复次数，下面分别对参数与搜索空间集的PDCCH重复次数的对应关系进行相应说明。
在具体实施中，覆盖恢复值可以与搜索空间集的PDCCH重复次数相关。也就是说，覆盖恢复值越大，则搜索空间集的PDCCH重复次数越大。
在本发明实施例中，当覆盖恢复值为3dB时，可以确定搜索空间集的PDCCH重复次数为2。当覆盖恢复值为6dB时，可以确定搜索空间集的PDCCH重复次数为4。当覆盖恢复值为9dB时，可以确定搜索空间集的PDCCH重复次数为8。
