Description

盲检能力优化方法和装置 技术领域
本公开涉及通信技术领域，具体而言，涉及盲检能力优化方法、及盲检能力优化装置、电子设备和计算机可读存储介质。
背景技术
在终端与基站的通信过程中，终端为了获取基站发送的下行控制信息(Downlink Control Information，简称DCI)，可以对物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)进行盲检。在相关技术中，终端的盲检能力是针对每个时隙slot限定的，但是如此配置存在一些问题。
具体在于，终端与基站主要在52.6GHz以下的频段中通信，在这种情况下，通信的子载波间隔(Subcarrier Spacing，简称SCS)可以为15kHz、30kHz、60kHz、120kHz，而一个时隙在时域上的长度与子载波是相关的。例如在子载波间隔为15kHz时，一个时隙为1ms，在子载波间隔为30kHz时，一个时隙为0.5ms，在子载波间隔为60kHz时，一个时隙为0.25ms，也即子载波间隔越大，时隙在时域上的长度越短。
但是随着频段的拓展，终端和基站也需要在60GHz以上的频段进行通信，而在高频段，为了应对相位噪声，需要扩大子载波间隔，例如子载波间隔为960kHz，在这种情况下，一个时隙为0.015625ms也即1/64ms。
可见，在高频段通信时，一个时隙的长度远小于1ms，然而终端的处理能力有限，在时隙极短的情况下，可能难以在每个时隙中都能根据下行控制信息来调度物理上行共享信道(Physical Uplink Shared Channel，简称PUSCH)/物理下行共享信道(Physical Downlink Shared Channel，简称PDSCH)，那么基站在这种情况下可以不在每个时隙中都配置承载下行控制信息的物理下行控制信道。那么在终端的盲检能力是针对每个时隙限定的情况下，终端的盲检能力就必须分散使用在每个时隙中，导致终端不能将盲检能力仅集中在配置有物理下行控制信道的时隙进行盲检而浪费终端的计算资源。
发明内容
有鉴于此，本公开的实施例提出了盲检能力优化方法、及盲检能力优化装置、电子设备和计算机可读存储介质，以解决相关技术中的技术问题。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1是根据本公开的实施例示出的一种盲检能力优化方法的示意流程图。本实施例所示的方法可以适用于终端，所述终端可以作为用户设备与基站进行通信，所述基站可以是5G基站，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。
如图1所示，盲检能力优化方法可以包括以下步骤：
在步骤S101中，确定盲检能力信息，其中，所述盲检能力信息包括第一子载波间隔下在每n个时隙检测物理下行控制信道候选的最大数目，和/或第一子载波间隔下在每n个时隙非重叠控制信道单元的最大数目，n为大于1的整数。
需要说明的是，第一子载波间隔下在每n个时隙非重叠控制信道单元的最大数目，针对终端而言，具体可以是第一子载波间隔下在每n个时隙能够盲检的非重叠控制信道单元的最大数目。
在一个实施例中，终端所确定的盲检能力信息，可以是预先存储在终端中的，例如位于终端与基站的通信协议预先规定的信息中。
其中，盲检能力信息可以主要包括两方面内容，一方面是第一子载波间隔下在每n个时隙检测物理下行控制信道候选的最大数目，另一方面是第一子载波间隔下在每n个时隙非重叠控制信道单元的最大数目，n为大于1的整数。
在相关技术中，在每个时隙检测物理下行控制信道候选的最大数目可以如图2A所示。每个时隙非重叠控制信道单元的最大数目可以如图3B所示。
在一个实施例中，第一子载波间隔下在每n个时隙检测物理下行控制信道候选的最大数目可以如图3A所示，以表格的形式存储在终端中。第一子载波间隔下在每n个时隙非重叠控制信道单元的最大数目可以如图3B所示，以表格的形式存储在终端中。
如图2A和图2B所示，在相关技术中，终端的盲检能力信息，是针对每个时隙进行限定的，例如在图2A中，在μ＝0的情况下，子载波间隔为15kHz，每个时隙检测物理下行控制信道候选的最大数目为44，每个时隙非重叠控制信道单元的最大数目为56。
图3A和图3B仅示出了μ为4、5、6，也即子载波间隔为240kHz、480kHz、960kHz的情况，而对于μ为0、1、2和3的情况，可以根据需要进行配置。其中图3A中具体的数值A1、A2和A3，以及图3B中具体的数值B1、B2和B3可以根据实际情况进行设置。
针对不同的子载波间隔，n可以不同，也可以相同；针对不同的子载波间隔，在每n个时隙检测物理下行控制信道候选的最大数目，可以不同，也可以相同；针对不同的子载波间隔，在每n个时隙非重叠控制信道单元的最大数目，可以不同，也可以相同。
以n＝4为例，在子载波间隔为960kHz的情况下，每4个时隙检测物理下行控制信道候选的最大数目为16，每4个时隙非重叠控制信道单元的最大数目为20。在相关技术中，由于终端的盲检能力是针对每个时隙配置的，那么在子载波间隔为960kHz 的情况下，若终端的盲检能力与本申请所述的上述实施例相同，那么配置到每个时隙，就是每个时隙检测物理下行控制信道候选的最大数目为4，每个时隙非重叠控制信道单元的最大数目为5。
例如终端根据基站发送的物理下行控制信道的资源信息，确定基站在4个时隙中的目标时隙内配置了物理下行控制信道。
基于相关技术中的盲检能力，终端在目标时隙最多只能检测4个物理下行控制信道候选，并且非重叠控制信道单元的最大数目为5。由于盲检能力是针对每个时隙配置的，导致部分盲检能力分散在未配置物理下行控制信道的时隙，浪费了盲检能力，而在目标时隙内检测物理下行控制信道候选的数目过少，造成基站只能在很有限的时频资源位置上选择用于承载调度DCI的时频资源，很难有时频域分集增益，而且在有其他DCI也待传输的情况下，极易造成PDCCH阻塞。。
而根据本公开的实施例，由于盲检能力是针对每n个时隙配置的，终端可以根据实际情况在n个时隙中灵活应用盲检能力，那么在确定了基站在4个时隙中的目标时隙内配置了物理下行控制信道时，可以将全部盲检能力应用在目标时隙，那么在目标时隙最多能够检测16个物理下行控制信道候选，并且非重叠控制信道单元的最大数目为20。据此，不易浪费盲检能力，并且在目标时隙内检测物理下行控制信道候选的个数足够多，有利于获得时频分集增益，且降低DCI阻塞概率。
需要说明的是，目标时隙的数量可以小于n，也可以等于n，具体可以根据基站配置的物理下行控制信道的资源信息确定。
可选地，所述第一子载波间隔大于120KHz。
可选地，所述第一子载波间隔为以下之一：
240KHz、480KHz、960KHz。
需要说明的是，第一子载波间隔的范围并不限于上述240KHz、480KHz、960KHz三个间隔，可以根据需要进行调整，例如第一子载波间隔还可以包含小于240KHz的间隔，也可以包含大于960KHz的间隔，具体可以是1920KHz等。
在一个实施例中，在子载波间隔(也即第一子载波间隔)较大的情况下，终端确定的盲检能力信息如上述实施例所述，也即第一子载波间隔下在每n个时隙检测物理下行控制信道候选的最大数目，和/或第一子载波间隔下在每n个时隙非重叠控制信道单元的最大数目。
由于在子载波间隔较大时，时隙的长度很短，终端的处理能力难以在每个时隙上调度物理下行共享信道，基站在这种情况下更有可能在每n个时隙的目标时隙中配置物理下行控制信道候选。因此终端在这种情况下确定的盲检能力信息，可以是针对每n个时隙配置的，以便在上述实施例的情况下，将全部盲检能力应用在目标时隙。
在一个实施例中，终端可以向基站上报处理能力，从而使得基站确定是否需要每n个时隙的目标时隙中配置物理下行控制信道候选，例如在终端的处理能力较弱时，具体可以是单位时间内能够处理数据的数据量大于预设值，基站在每n个时隙的目标时隙中配置物理下行控制信道候选；在终端的处理能力较强时，基站在每个时隙的目标时隙中配置物理下行控制信道候选。具体可以是单位时间内能够处理数据的数据量小于预设值。
可选地，所述盲检能力信息还包括第二子载波间隔下在每个时隙检测物理下行控制信道候选的最大数目，和/或第二子载波间隔下在每个时隙非重叠控制信道单元的最大数目，其中，所述第二子载波间隔小于所述第一子载波间隔。
可选地，所述第二子载波间隔为以下之一：
15KHz、30KHz、60KHz、120KHz。
需要说明的是，第二子载波间隔和上述实施例中的第一子载波间隔，都是终端和基站通信的子载波间隔，一般情况下，在一次通信过程中子载波间隔是固定不变，而在不同次通信过程中，例如终端与基站断开通信连接后，再次接入基站与基站进行通信，那么子载波间隔可以与前一次通信时的子载波间隔不同。
在一个实施例中，在子载波间隔(也即第二子载波间隔)较小的情况下，终端确定的盲检能力信息，可以是每个时隙检测物理下行控制信道候选的最大数目，和/或第二子载波间隔下在每个时隙非重叠控制信道单元的最大数目。
由于在子载波间隔较大时，时隙的长度相对较长，终端的处理能力容易在每个时隙上调度物理下行共享信道，基站在这种情况下更有可能在每个时隙的目标时隙中配置物理下行控制信道候选。因此终端在这种情况下确定的盲检能力信息，可以是针对每个时隙配置的，无需终端计算在每个时隙中如何分配盲检能力，有利于减少终端的工作量。
图4是根据本公开的实施例示出的另一种盲检能力优化方法的示意流程图。如图4所示，所述方法还包括：
在步骤S102中，接收基站发送的物理下行控制信道的资源信息；资源信息具体可以由时域资源信息和频域资源信息构成。
在步骤S103中，根据所述资源信息确定所述物理下行控制信道在所述n个时隙中所处的目标时隙；
在步骤S104中，根据所述盲检能力信息在所述目标时隙的物理下行控制信道中盲检下行控制信息。
可选地，所述资源信息包括控制资源集和搜索空间。
在一个实施例中，基站可以向终端发送物理下行控制信道的资源信息，所述资源信息可以包括控制资源集CORESET和搜索空间Search Space，终端根据资源信息可以确定物理下行控制信道在n个时隙中所处的目标时隙，那么终端可以根据盲检能力信息在所述目标时隙的物理下行控制信道中盲检下行控制信息。
需要说明的是，目标时隙可以是每n个时隙中的一个时隙，也可以是每n个时隙中的多个时隙，在目标时隙是每n个时隙中的多个时隙的情况下，终端可以将盲检能力均分在多个时隙的每个时隙中。
例如n为4，目标时隙为每4个时隙中的第3个时隙，那么终端可以将全部盲检能力应用在每4个时隙中的第3个时隙中，以便在目标时隙内足够多数目的检测物理下行控制信道候选，有利于检测到承载了下行控制信息的物理下行控制信道。
例如n为4，目标时隙为每4个时隙中的第2和第3个时隙，那么终端可以将全部盲检能力均分在第2和第3个时隙，以便在这两个目标时隙内都有相同可能性检测到承载了下行控制信息的物理下行控制信道。

可选地，所述第一子载波间隔为以下之一：
240KHz、480KHz、960KHz。
