Description

用于无线通信系统的电子设备、方法和存储介质 技术领域
本公开一般地涉及无线通信系统，并且具体地涉及与盲检测有关的技术。
背景技术
在现行的通信技术(例如，LTE、5G之类)下，终端设备在解码物理下行控制信道(Physical Downlink Control Channel，PDCCH)之前，并不知道解码所需的信息，诸如，要进行解码的资源的位置、结构(例如，聚合等级、交织参数等)以及扰码(例如，无线网络临时标识(Radio Network Tempory Identity，RNTI)等)之类。终端设备实际上仅仅知道在下行链路资源网格中的一定范围内的资源上可能携带PDCCH。因此，终端设备需要在这个范围内尝试对PDCCH解码，也就是进行盲检测。
在进行盲检测时，终端设备需要对多个候选PDCCH尝试进行解码，例如，多个候选PDCCH可以对应于不同的下行链路控制信息(Downlink Control Information，DCI)格式和/或聚合等级。可以将多个候选PDCCH的子集配置为搜索空间集合(Search Space Set，SSS)。在终端设备可以根据来自基站的显示或隐式的指示，在一个或多个SSS上进行盲检测。目前，已经存在如下技术构思：将多个SSS划分为设置有不同监听频率的至少两个搜索空间集组(Search Space Set Group，SSSG)，并针对不同情况(例如，是否处于信道占用时间(Channel Occupancy Time,COT)期间)来切换SSSG，以在不同疏密程度的搜索空间集合组上进行监听。
目前还在讨论一种称为PDCCH skipping的技术构思。在该技术构思下，可以在特定的SSSG内在一些条件下跳过对PDCCH的监听以进一步减少功率消耗。
现有的上述技术构思仅仅为所有UE统一设置支持稀疏监听或密集监听的SSSG并进行SSSG之间的切换，并且对PDCCH监听的控制也仅仅局限于“对SSS进行限制”这一个维度。但是，存在其他导致对一个或多个SSS进行切换的因素，并且对监听的控制不仅仅限于切换SSSG。
鉴于以上，需要一种对在一个或多个SSS上的监听进行控制的更灵活的方案。

具体实施方式
以下描述根据本公开的设备和方法等各方面的代表性应用。这些例子的描述仅是为了增加上下文并帮助理解所描述的实施例。因此，对本领域技术人员而言明晰的是，以下所描述的实施例可以在没有具体细节当中的一些或全部的情况下被实施。在其他情况下，众所周知的过程步骤没有详细描述，以避免不必要地模糊所描述的实施例。其他应用也是可能的，本公开的方案并不限制于这些示例。
典型地，无线通信系统至少包括控制设备和终端设备，控制设备可以为一个或多个终端设备提供通信服务。
在本公开中，术语“基站”或“控制设备”具有其通常含义的全部广度，并且至少包括作为无线通信系统或无线电系统的一部分以便于通信的无线通信站。作为例子，基站例如可以是4G通信标准的eNB、5G NR通信标准的gNB、远程无线电头端、无线接入点、无人机控制塔台或者执行类似功能的通信装置。在本公开中，“基站”和“控制设备”可以互换地使用，或者“控制设备”可以实现为“基站”的一部分。下文将以基站为例结合 附图详细描述基站/终端设备的应用示例。
在本公开中，术语“终端设备”或“用户设备(UE)”具有其通常含义的全部广度，并且至少包括作为无线通信系统或无线电系统的一部分以便于通信的终端设备。作为例子，终端设备例如可以是移动电话、膝上型电脑、平板电脑、车载通信设备、可穿戴设备、传感器等之类的终端设备或其元件。在本公开中，“终端设备”和“用户设备”(以下可被简称为“UE”)可以互换地使用，或者“终端设备”可以实现为“用户设备”的一部分。
在本公开中，术语“控制设备侧”/“基站侧”具有其通常含义的全部广度，通常指示通信系统下行链路中发送数据的一侧。类似地，术语“终端设备侧”/“用户设备侧”具有其通常含义的全部广度，并且相应地可以指示通信系统下行链路中接收数据的一侧。
在本公开中，除非另有说明，术语“监听”指的是在盲检测期间，在一个或多个SSS上尝试对候选PDCCH进行解码，其中，每个候选PDCCH可以对应于某个特定的DCI格式和某个特定的聚合等级。
应指出，以下虽然主要基于包含基站和用户设备的通信系统对本公开的实施例进行了描述，但是这些描述可以相应地扩展到包含任何其它类型的控制设备侧和终端设备侧的通信系统的情况。例如，对于下行链路的情况，控制设备侧的操作可对应于基站的操作，而用户设备侧的操作可相应地对应于终端设备的操作。
传统地，在进行盲检测时，如在背景技术中描述的，已经存在如下技术构思：将SSS划分为设置有不同监听密度(换句话说，监听时刻(Monitoring Occasion，MO)密度)的至少两个SSSG，并针对不同情况来切换SSSG，以在不同的搜索空间集合组上进行监听，从而实现对监听频率的控制。例如，在COT期间以外的任何时间，由于UE知道的信息有限，需要以较密集地方式进行监听，例如，在具有更密集监听时刻的SSSG上进行监听。而在COT期间内，由于UE已经获得了一些额外的信息(例如，UE已经知道了COT配置信息)，因此可以适当以更稀疏的方式进行监听，例如，在具有更稀疏监听时刻的SSSG上进行监听。这种按照监听的疏密程度的对SSSG的切换使得UE可以减少功率消耗。
此外，为了进一步减少功率消耗，如在背景技术中描述的，目前还在讨论一种称为PDCCH skipping的技术构思。在该技术构思下，构建特殊的SSSG。具体而言，这种特殊的SSSG可以是不包括SSS的空SSSG，从而使得当切换到该SSSG时，UE不进行PDCCH的监听。或者，这种特殊的SSSG可以是由特定SSS构成的SSSG，这些特定的SSS被配置为使得UE仅仅在特定条件(例如，混合自动重传请求(HybridAutomatic Repeat reQuest， HARQ)否定确认(NACK)，或往返时延(Round-Trip Time，RTT)/收发(ReTx)定时器)下才对这些SSS进行监听。
这些现有的讨论仅仅涉及对SSS监听进行控制的非常有限的方式。然而，实际上，需要对在一个或多个SSS上的监听进行更灵活的控制。
具体而言，本公开注意到以下两个可以改进的方面：
一方面，随着通信技术的发展以及通信技术所支持的垂直业务的拓展，存在越来越多的能力不同的UE。例如，存在功能削减(Reduced Capability，redcap)NR设备，这种UE主要在工业无线传感器网络、视频监控和可穿戴设备之类的要求尽可能降低功耗、延长电池使用寿命的场景下，并且这种UE可能在预定的监听时段内只能进行次数较少的监听。再例如，还存在支持高可靠和低延迟通信(Ultra-reliable and Low Latency Communications，URLLC)的UE，这种UE可能对延迟的容忍度较低，因此期望能够尽可能低延迟地检测到PDCCH。又例如，存在支持多种PDCCH监听能力的高级UE，这种UE可能支持不同类型的监听规则，换句话说，具有不同的监听能力，例如，不同的监听能力可以表示支持不同密度和/或一段时间内不同次数的监听，并且可能需要根据该UE所处的使用场景来切换要应用的监听能力。
然而，现有的技术构思仅仅为所有类型的UE统一设置了进行稀疏或密集监听的SSSG，并不存在针对UE，特别是UE支持的监听能力来设置SSS切换的方案。因此，可以考虑基于UE的监听能力的SSS切换，从而实现更细粒度的灵活可调的SSS切换方案。
另一方面，如上文介绍的，现有的技术构思仅仅提出了通过设置特殊的SSS以构成特殊的SSSG，来控制减少监听。这种现有的技术构思仅仅是从SSS层面出发来减少监听。实际上，本公开注意到，还可以通过减少SSS内要监听的候选PDCCH的数量出发来减少监听。例如，本公开注意到，在一些情况下，下行链路上要发送的控制信息可能会集中在一些特定格式或大小的DCI上，因此，可能期望UE仅对符合这些特定格式或大小的候选PDCCH进行监听，而不是监听所有候选PDCCH。因此，可以考虑通过限制DCI格式或大小来限制要监听的候选PDCCH的数量，从而实现监听次数的自适应调整。
鉴于以上两个方面，本公开提出了对在一个或多个SSS上的监听进行灵活控制的方案。
第一实施例
根据本公开的第一实施例，在盲检测期间，可以执行基于UE的监听能力的SSS切换。例如，UE可以将其支持的一个或多个监听能力的能力信息和与每个监听能力相关联的监听能力标识符发送到基站。基站可以将与每个监听能力相关联的一个或多个SSS与接收到的与该监听能力相关联的监听能力标识符进行关联，并向UE发送至少指示了SSS与监听能力标识符之间的这种关联的SSS配置信息。基站可以通过向UE发送包括特定的一个或多个监听能力标识符的DCI来指示UE将要监听的一个或多个SSS。
下边将结合图1-图8对第一实施例进行详细说明书。
根据本公开的第一实施例的基站的结构及操作流程
首先将参考图1说明根据本公开的实施例的用于控制设备/基站的电子设备10的概念性结构
如图1所示，电子设备10可以包括处理电路102。该处理电路102可以被配置为通过以下操作来执行基于UE的监听能力的SSS切换：从UE接收指示UE支持的一个或多个监听能力的能力信息和与每个监听能力相关联的监听能力标识符；将与所述一个或多个监听能力中的每个监听能力相关联的一个或多个SSS与和该监听能力相关联的监听能力标识符进行关联；向UE发送SSS配置信息，其中，所述SSS配置信息至少指示与每个SSS相关联的监听能力标识符；和向UE发送包括第一监听能力标识符的DCI，以向UE指示UE将要监听的一个或多个SSS。
处理电路102可以是通用处理器的形式，也可以是专用处理电路，例如ASIC。例如，处理电路102能够由电路(硬件)或中央处理设备(诸如，中央处理单元(CPU))构造。此外，处理电路102上可以承载用于使电路(硬件)或中央处理设备工作的程序(软件)。该程序能够存储在存储器(诸如，布置在存储器104中)或从外面连接的外部存储介质中，以及经网络(诸如，互联网)下载。
在一个实现中，处理电路102可以包括SSS设置单元。该SSS设置单元可以根据UE上报的监听能力，为UE设置与该监听能力对应的要在其上进行监听的一个或多个SSS，并将每个监听能力标识符(以下也简称为监听能力ID)与对应于该监听能力标识符所识别的监听能力的一个或多个SSS相关联。
在一个实现中，处理电路102还可以包括SSS配置信息生成单元。该SSS配置信息生成单元例如可以生成SSS配置信息。UE利用SSS配置信息可以获得与基站为其配置的SSS相关的信息，以在盲检测时使用。特别地，根据本实施例的SSS配置信息至少可以指 示与每个SSS相关联的监听能力ID，即指示每个SSS和相应的监听能力ID之间的关联关系。
此外，处理电路102还可以包括控制与UE进行通信(可选地经由通信单元106)的通信控制单元。该通信控制单元例如可以控制从UE接收指示UE支持的一个或多个监听能力的能力信息和与每个监听能力相关联的监听能力ID；控制向UE发送上述SSS配置信息；控制向UE发送指示随后要监听的一个或多个SSS的信息；以及可选地，控制从UE接收指示与UE期望切换到的一个或多个SSS关联的监听能力IE，等等。
可选地，电子设备10还可以包括图中以虚线示出的存储器104以及通信单元106。此外，电子设备20还可以包括未示出的其它部件，诸如射频链路、基带处理单元、网络接口、处理器、控制器等。处理电路102可以与存储器104和/或通信单元106关联。例如，处理电路102可以直接或间接(例如，中间可能连接有其它部件)连接到存储器104，以进行数据的存取。还例如，处理电路102可以直接或间接连接到通信单元106，以经由通信单元106发送无线电信号以及经由通信单元106接收无线电信号。
存储器104可以存储由处理电路102产生的各种信息(例如，从UE接收的监听能力及相应的监听能力ID、生成SSS配置信息所需的参数/信息以及生成的SSS配置信息等)、用于电子设备10操作的程序和数据、将由通信单元106发送的数据等。存储器104用虚线绘出，因为它还可以位于处理电路102内或者位于电子设备10外。存储器104可以是易失性存储器和/或非易失性存储器。例如，存储器104可以包括但不限于随机存储存储器(RAM)、动态随机存储存储器(DRAM)、静态随机存取存储器(SRAM)、只读存储器(ROM)、闪存存储器。
通信单元106可以被配置为在处理电路102(例如通信控制单元)的控制下与终端设备进行通信。在一个示例中，通信单元106可以被实现为发射机或收发机，包括天线阵列和/或射频链路等通信部件。
虽然图1中示出了处理电路102与通信单元106分离，但是处理电路102也可以被实现为包括通信单元106，例如，与通信控制单元相结合地实现。此外，处理电路102还可以被实现为包括电子设备10中的一个或多个其它部件，或者处理电路102可以被实现为电子设备10本身。在实际实现时，处理电路102可以被实现为芯片(诸如包括单个晶片的集成电路模块)、硬件部件或完整的产品。
应注意，上述各个单元仅是根据其所实现的具体功能划分的逻辑模块，而不是用于限制具体的实现方式，例如可以以软件、硬件或者软硬件结合的方式来实现。在实际实 现时，上述各个单元可被实现为独立的物理实体，或者也可由单个实体(例如，处理器(CPU或DSP等)、集成电路等)来实现。此外，上述各个单元在附图中用虚线示出指示这些单元可以并不实际存在，而它们所实现的操作/功能可由处理电路本身来实现。
下面，将参考图2示出的控制设备/基站侧的概念性操作流程20来详细说明作为基站的电子设备10所实施的各操作。
基站的操作开始于S202。
在S204处，基站从UE接收指示该UE支持的一个或多个监听能力的能力信息和与每个监听能力相关联的监听能力ID。
根据本公开，不同的监听能力可以表示支持不同密度和/或一段时间内不同次数的监听。具体而言，监听能力包括以下中的一个或多个：一种或多种类型的监听平面(monitoring span)、多种类型的监听span中的部分或全部监听span构成的一个或多个span组，和每时隙的监听能力和每多个时隙的监听能力。
例如，UE可以支持每时隙的监听能力，例如，如针对NR的3GPP R15标准中规定的那样。在这种监听能力下，每个时隙内能够进行监听的次数(换句话说PDCCH的盲检测次数)的上限被限制到比较小的值。在上报监听能力时，UE可以直接用信号表示其支持每时隙的监听能力。类似地，UE还可以支持每多个时隙的监听能力。
为了提高盲检测能力(例如，监听次数和盲检测可靠性等)，一些标准(例如，针对NR的3GPP R16)规定了每监听平面的盲检测。这里，平面(或者窗口)(英文术语为span)是一个时隙内UE要监听的一系列符号，并且一个时隙内可以包含多个平面。在扩展情况下，例如，如针对NR的3GPP R17正在讨论的，也可以跨多个时隙定义平面(也可以称为扩展平面(extended span)，在这种情况下，可以跨相邻的两个时隙来设置一个监听平面，并且多个时隙可以联合地包含多个监听平面。无论是每时隙的监听平面还是多时隙的监听平面，均按照监听平面(也可称为盲检测时间窗)来设置监听次数的上限。
UE可以支持一种或多种类型的监听span，例如，每时隙的监听span下的一种或多种类型的监听span，和/或多时隙的监听span下的一种或多种类型的监听span。这里，监听span的类型是按照如下的(X、Y)这两个因素来划分的：
X-两个连续span的第一个符号之间的最小间隔，和
Y-span的最大监听时间长度。
在不同类型的监听span下，在一个span内能够进行监听的次数的上限不同。在上报监听能力时，UE可以直接上报其支持的监听span的类型。例如，UE可以直接上报其支持的(X， Y)的各种组合，例如，(2，2)、(4，3)、(7，3)之类。
进一步地，可以将UE支持的一种或多种类型的监听span进行组合以形成span组。因此，UE上报的监听能力可以包括其支持的多种类型的监听span中的部分或全部监听span构成的span组。例如，再次采用上文描述的(X、Y)表示法，UE支持的span组可以是((2，2)、(4，3))。
要说明的是，UE的监听能力不限于上文详细说明的那些能力。UE还可以支持任何其他适用的监听能力。
根据本公开，UE在上报其支持的一个或多个监听能力时，可以连同监听能力上报与每个监听能力相关联的监听能力ID。例如，假设UE支持以下五中监听能力：
-每时隙的监听能力；
-(2，2)类型的span；
-(4，3)类型的span；
-(7，3)类型的span；和
-((2，2)、(4，3))的span组，
那么，UE可以进行如下方式的监听能力上报：
-监听能力ID 0：每时隙的监听能力；
-监听能力ID 1：(2，2)类型的span；
-监听能力ID 2：(4，3)类型的span；
-监听能力ID 3：(7，3)类型的span；和
-监听能力ID 4：((2，2)、(4，3))的span组。
应注意的是，UE可以按任意适当的方式上报监听能力和对应的监听能力ID，只要每个监听能力能够与其监听能力ID相关联即可。
继续参考图2，在S206，基站可以按照相关的配置参数针对UE的每个监听能力配置一个或多个SSS，并将与每个监听能力相关联的一个或多个SSS与和该监听能力相关联的监听能力ID进行关联。可以按照任何恰当的方式通过配置参数来针对每个能力配置SSS，例如，如3GPP标准中规定的那样，本文不再详细描述。
根据本公开，需要将为每个监听能力配置的一个或多个SSS与和该监听能力相关联的监听能力ID进行关联。例如，基站可以在配置SSS时添加关于监听能力ID指示/配置的参数配置，从而使得能够将针对某个特定监听能力配置的SSS与和该监听能力关联的监听能力ID进行映射。可以理解的是，将与监听能力关联的一个或多个SSS与相应的监 听能力ID进行关联的方式不限于这里举出的例子，基站可以采用任何恰当的方式进行这种关联，只要对于任意SSS，基站能够识别出与其关联的监听能力ID即可。
图3A示出了SSS 0-9与多个监听能力(这里是多个不同类型的监听平面)之间的关联。如图所示，对于监听能力ID为0的span，基站配置了SSS 0-6这七个SSS。对于监听能力ID为1的span，基站配置了SSS 0、SSS 2、SSS 4、SSS 7这四个SSS。对于监听能力ID为2的span，基站配置了SSS 3和SSS 8这两个SSS。对于监听能力ID为3的span，基站配置了SSS 5-9这5个SSS。可以看出，对于不同的监听能力配置的SSS可以存在部分重叠。也就是说，一个SSS可以与一个或多个监听能力ID相关联。此外，两个不同的监听能力ID可以对应于完全相同、部分相同或完全不同的两组一个或多个SSS。
如上文详细说明的，UE可以支持不同类别的多种监听能力。例如，除了图3A中示出的不同类型的监听span之外，UE还可以支持不同的span组。图3B进一步示出了SSS 0-9与UE支持的两个span组之间的关联。要注意的是，为了更加清晰地表示span组与SSS之间的关联，在图3B中没有示出图3A中已经示出的SSS 0-9与UE支持的多个不同类型的监听span之间的关联。如图3B所示，UE可以支持监听能力ID为4的由span 0和span 1构成的span组，以及监听能力ID为5的由span 2和span 3构成的span组。参照图3A中示出的为每个span配置的SSS，SSS 0-7这八个SSS可以与监听能力ID 4相关联，而SSS 3、5-9这六个SSS可以与监听能力ID 5相关联。
当然，图3A与3B仅仅是为了示意SSS与监听能力之间的关联而示出的。在UE支持更多或更少的监听能力的情况下，还可以相应地存在更多或更少的这种关联。
继续参考图2，在S210，基站将SSS配置信息发送给UE。根据本公开，SSS配置信息至少可以指示与每个SSS相关联的监听能力ID，从而使得UE也能够知道每个SSS与其不同能力之间的对应关系。此外，根据SSS配置信息，UE可以知道基站为其配置了什么样的SSS(例如，如本领域技术人员已知的用于确定SSS的关联的控制资源集合(Control Resource Set，CORESET)、聚合等级、检测周期等信息的参数)。例如，基站可以利用无线资源控制(Radio Resource Control，RRC)信令将SSS配置信息发送给UE。
接下来，在S214，基站可以向UE指示该UE将要监听的一个或多个SSS。基站可以通过向UE发送包括一个或多个监听能力ID的消息来向UE显示地指示该UE将要监听与该一个或多个监听能力ID相关联的一个或多个SSS。例如，基站可以通过DCI消息(诸如DCI 2-0和调度DCI 1-0，DCI 1-1，调度DCI 1-2、调度DCI 0-0、调度DCI 0-1和调度DCI 0-2之类)来进行这种指示。
在本文中，基于监听能力ID确定的期望监听或要监听的一个或多个SSS可以被称为SSS束(SSS Bundle，SSSB)。
再次参考图3A与图3B，例如，基站可以向UE发送指示监听能力ID 0的DCI，那么在接收并解码了该DCI之后，UE可以切换到由SSS 0-6构成的SSSB。再例如，基站可以向UE发送指示监听能力ID 0和ID1的DCI，那么在接收并解码了该DCI之后，UE可以切换到由SSS 0-7构成的SSSB。又例如，基站可以向UE发送指示监听能力ID 5的DCI，那么在接收并解码了该DCI之后，UE可以切换到由SSS 3、5-9构成的SSSB。要说明的是，切换可能并不是立即发生的，例如，UE可能在预定的时间之后完成这种切换。
例如，基站可以根据当前的资源情况和/或通信场景等来自主判断需要进行SSS的切换。例如，在当前通信场景可能需要低延迟的情况下，基站可指示UE切换到针对支持更频繁监听的监听能力而配置的一个或多个SSS，从而尽可能早地检测到PDCCH。再例如，在当前通信场景可能需要高可靠性的情况下，基站可以指示UE切换到为每个盲检测时机基站还可以综合考虑不同的需求，选择分别对应不同需求的多组SSS的组合。例如，在URLLC场景下，可能需要同时满足可靠性和低延迟，因此，基站可以向UE发送包括与同时满足这两个需求的一组SSS相关联的监听能力ID，或者包括与分别满足这两个需求的两组SSS相关联的监听能力ID的DCI。
此外，如图2虚线框S212所示出的，基站可以从UE接收指示与由该UE期望切换到的一个或多个SSS相对应的一个或多个监听能力ID，并且基于UE上报的期望的监听能力ID以及资源情况来确定要向UE通知的监听能力ID。
例如，在资源较充沛的情况下，基站可以按照UE的需求，指示UE将监听与该UE上报的监听能力ID对应的一个或多个SSS。即在这种情况下，基站可以向UE发送与UE上报的监听能力ID相同的监听能力ID。再例如，在资源比较紧缺或相应资源已被占用的情况下，基站可以在考虑UE的需求的基础上，向UE发送与UE期望的监听能力ID不同的另外的一个或多个监听能力ID。在这种情况下，这种另外的监听能力ID可指示尽可能满足UE需求的次优的一个或多个SSS。特别地，这种另外的监听能力ID可以是与当前UE正在监听的一个或多个SSS对应的监听能力ID，即基站可以指示UE继续在当前SSS上进行监听。例如，假设在UE正在与监听能力1对应的SSSB上监听并且期望切换到监听能力2，基站可以综合考虑当前的资源状况和UE的需求，指示UE切换到与监听能力2对应的SSSB，或者切换到与监听能力3对应的SSSB，或者继续在与监听能力1对应的SSSB上进行监听。
根据本公开第一实施例的方案也可以与上文介绍的传统的针对监听疏密在两个SSSG之间进行切换的方案相结合，从而实现更细粒度的SSS切换。在这种结合实施的情况下，可以在SSS配置信息中包括关于SSSG组的设置信息(例如，哪些SSS构成哪组SSSG)，并且基站可以向UE发送包括指示监听能力ID(在UE上报了期望的监听能力ID的情况下如上文解释的，与UE上报的期望的监听能力ID相同或不同)的信息和指示SSSG的DCI，从而指示UE要切换到由与该监听能力ID相关联的一个或多个SSS构成的SSSB与所述SSSG之间重叠的一个或多个SSS进行监听。
例如，如图4所示，基站可以向UE发送指示监听能力ID 5和SSSG 0的DCI，那么在接收并解码了该DCI之后，UE可以切换到由SSS 3、5-9构成的SSSB与由SSS 0-7构成的SSSG之间的交集，即SSS 3、5-7。这种结合实施的方案可以同时考虑如下两个维度：(1)基站为各个UE统一设置的监听疏密程度(体现为具有不同监听时刻密度的SSSG)；和(2)每个UE想要应用的监听能力，从而能够按照更细的粒度实现灵活多样的SSS切换，从而满足不同场景下不同UE的需求。
根据本公开第一实施例的方案也可以与下文将详细介绍的第二实施例的方案相结合，这种结合的详细实施方式也将在下文详细描述。
再次参考图2，基站的概念性操作流程在S216处结束。
要指出的是，图2所示的基站的操作步骤仅仅是示意性的。在实践中，基站的操作还可以包括一些附加或替代的步骤。例如，如虚线框中的S208所示出的，可选地，基站还可以向UE通知是否启用按照本公开第一实施例的基于UE的监听能力的SSS切换。例如，可以通过RRC信令向UE通知是否启用基于UE的监听能力SSS切换。例如，在不进行这种通知步骤的情况下，基站和UE之间可以按照约定默认启用或不启用这种切换。此外，这种通知步骤也可以并非在图2所示的步骤次序处执行。例如，该通知也在S204之前或之后进行，只要基站能够使UE在恰当的时候知道是否启用这种切换即可。再例如，可选地，在S212，基站可以从UE接收指示与由该UE期望切换到的一个或多个SSS相对应的监听能力ID。例如，UE可以上报一个或多个监听能力ID。如上文所述，在不进行S212的情况下，基站将主动指示UE进行SSS切换。
根据本公开的第一实施例的UE的结构和操作流程
上文详细说明了根据本公开的基站的示例性结构以及示例性操作。下面，将结合图5-图6说明根据本公开的终端设备的示例性结构以及示例性操作流程。
首先将参考图5说明根据本公开的实施例的用于终端设备/UE的电子设备50的概念性结构
如图5所示，电子设备50可以包括处理电路502。该处理电路502可以被配置为通过以下操作来执行基于电子设备50的监听能力的SSS切换：向基站发送指示电子设备50支持的一个或多个监听能力的能力信息和与每个监听能力相关联的监听能力ID，使得基站能够将与所述一个或多个监听能力中的每个监听能力相关联的一个或多个SSS与和该监听能力相关联的监听能力ID进行关联；从所述基站接收SSS配置信息，其中，SSS配置信息至少指示与每个SSS相关联的监听能力ID；和从基站接收包括第一监听能力标识符的DCI，所述DCI指示电子设备50将要监听的一个或多个SSS。
处理电路502可以是通用处理器的形式，也可以是专用处理电路，例如ASIC。例如，处理电路502能够由电路(硬件)或中央处理设备(诸如，中央处理单元(CPU))构造。此外，处理电路502上可以承载用于使电路(硬件)或中央处理设备工作的程序(软件)。该程序能够存储在存储器(诸如，布置在存储器504中)或从外面连接的外部存储介质中，以及经网络(诸如，互联网)下载。
在一个实现中，处理电路502可以包括确定电子设备50的监听能力的监听能力确定单元。已经在上文详细说明了UE的监听能力，这里不再赘述。
处理电路502还可以包括SSS切换确定单元。该SSS切换确定单元例如，可以确定是否发生了节能事件、定时器超时或其他可能触发SSS切换的事件，并且在肯定情况下，确定需要发生SSS切换，并确定需要切换到与哪一个或多个监听能力ID相关联的一个或多个SSS。
处理电路502还可以包括控制与基站进行通信(可选地经由通信单元506)的通信控制单元。该通信控制单元例如可以控制向基站发送指示电子设备50支持的一个或多个监听能力的能力信息和与每个监听能力相关联的监听能力ID；控制从基站接收至少指示了每个SSS与相应的监听能力ID之间的关联的SSS配置信息；可选地控制向基站发送指示与电子设备50期望切换到的一个或多个SSS关联的监听能力IE；和控制从基站接收指示随后要监听的一个或多个SSS的信息。
此外，可选地，电子设备50还可以包括图中以虚线示出的存储器504以及通信单元506。此外，电子设备50还可以包括未示出的其它部件，诸如射频链路、基带处理单元、网络接口、处理器、控制器等。处理电路502可以与存储器504和/或通信单元506关联。例如，处理电路502可以直接或间接(例如，中间可能连接有其它部件)连接到存储器504， 以进行数据的存取。还例如，处理电路502可以直接或间接连接到通信单元506，以经由通信单元506发送无线电信号以及经由通信单元506接收无线电信号。
存储器504可以存储由处理电路502产生的各种信息(例如，电子设备50支持的监听能力及相应的监听能力ID和从基站接收的SSS配置信息等)、用于电子设备50操作的程序和数据、将由通信单元506发送的数据等。存储器504用虚线绘出，因为它还可以位于处理电路502内或者位于电子设备50外。存储器504可以是易失性存储器和/或非易失性存储器。例如，存储器504可以包括但不限于随机存储存储器(RAM)、动态随机存储存储器(DRAM)、静态随机存取存储器(SRAM)、只读存储器(ROM)、闪存存储器。
通信单元506可以被配置为在处理电路502(例如通信控制单元)的控制下与基站进行通信。在一个示例中，通信单元506可以被实现为发射机或收发机，包括天线阵列和/或射频链路等通信部件。
虽然图5中示出了处理电路502与通信单元506分离，但是处理电路502也可以被实现为包括通信单元506。此外，处理电路502还可以被实现为包括电子设备50中的一个或多个其它部件，或者处理电路502可以被实现为电子设备50本身。在实际实现时，处理电路502可以被实现为芯片(诸如包括单个晶片的集成电路模块)、硬件部件或完整的产品。
应注意，上述各个单元仅是根据其所实现的具体功能划分的逻辑模块，而不是用于限制具体的实现方式，例如可以以软件、硬件或者软硬件结合的方式来实现。在实际实现时，上述各个单元可被实现为独立的物理实体，或者也可由单个实体(例如，处理器(CPU或DSP等)、集成电路等)来实现。此外，上述各个单元在附图中用虚线示出指示这些单元可以并不实际存在，而它们所实现的操作/功能可由处理电路本身来实现。
下面，将参考图6说明作为终端设备/UE侧的电子设备50的概念性操作流程60。
基站的操作开始于S602。
在S604处，UE向基站发送指示UE支持的一个或多个监听能力的能力信息和与每个监听能力相关联的监听能力ID，使得基站能够将与所述一个或多个监听能力中的每个监听能力相关联的一个或多个SSS与和该监听能力相关联的监听能力ID进行关联。如上文详细说明的，UE支持的监听能力可以是一种或多种类型的监听span、由多种类型的监听span中的部分或全部监听span构成的一个或多个span组、每时隙的监听能力和每多个时隙的监听能力。UE可以连同监听能力上报与每个监听能力相关联的监听能力ID，使得基站可以知道从UE接收的每个监听能力与相应的监听能力ID之间的对应关系。
在S608处，UE从基站接收SSS配置信息，其中，SSS配置信息至少指示与每个SSS相关联的监听能力标识符。根据SSS配置信息，UE可以知道基站为其配置了什么样的SSS，从而能够根据SSS配置信息来确定SSS的关联的CORESET、SSS中候选PDCCH的时频资源位置、聚合等级等信息，以便接下来在相应的SSS上进行监听以进行盲检测。例如，UE可以经由RRC信令来接收SSS配置信息。
接下来，可选地在S610，UE可以向基站发送一个或多个监听能力ID，这一个或多个监听能力ID可以指示UE期望切换到的由与这一个或多个监听能力ID相关联的一个或多个SSS构成的SSSB。
例如，UE可能会出于节能事件、定时器超时或其他原因等上报一个或多个监听能力ID来指示其期望切换到的SSS。例如，UE可能检测到即将进入节能模式，因此，该UE可能期望切换到针对支持更少监听次数的监听能力而配置的一个或多个SSS，从而尽可能减少监听次数以降低功耗。再例如，UE可能检测到即将进入需要低延迟的场景，因此，该UE可能期望切换到针对支持更频繁监听的监听能力而配置的一个或多个SSS，从而尽可能早地检测到PDCCH。再例如，UE可能检测到即将进入需要高可靠性的场景，因此，该UE可能期望切换到为每个盲检测时机分配了更多资源的一个或多个SSS，从而尽可能可靠地检测到PDCCH。UE还可以综合考虑不同的需求，选择分别对应不同需求的多组SSS的组合。例如，在URLLC场景下，UE可能需要同时满足可靠性和低延迟，因此，UE可以通过上报监听能力ID来向基站上报同时满足这两个需求的一组SSS，或分别满足这两个需求的两组SSS。
例如，UE可以经由用户辅助信息(UE Assistant Information，UAI)或媒体接入控制的控制元素(Media Access Control Control Element，MAC CE)或任何其他适用的信令接收监听能力ID。
例如，UE可以经由UAI或MAC CE或任何其他适用的信令来上报一个或多个监听能力ID。
接下来，在S612，UE可以从基站接收指示将要监听的一个或多个SSS的信息。在未进行S610的情况下，将要监听的一个或多个SSS是由基站自主确定的。如上文说明的，UE可以从基站接收发送包括指示一个或多个监听能力ID的消息，诸如DCI消息(诸如DCI 2-0和调度DCI 1-1，调度DCI 0-1和调度DCI 0-2之类)之类。响应于接收到这种包括监听能力ID的消息，UE可以(例如，在预定时间之后)切换到与该监听能力ID对应的一个或多个SSS进行监听。根据基站侧对UE的需求以及当前资源分配情况的综合考虑，UE 从基站接收到的一个或多个监听能力ID可以与其上报的期望的监听能力ID相同或不同，并且接收到的监听能力ID可以指示UE当前正在监听的一个或多个SSS(也就是说，在这种情况下，UE不做切换而是继续在当前SSS上进行监听)。
如上文详细说明的，在根据本公开第一实施例的方案与传统的针对监听频率在两个SSSG之间进行切换的方案结合实施的情况下，UE可以从基站接收包括指示监听能力ID的信息和指示SSSG的DCI。响应于接收到这种DCI，UE可以切换到由与该监听能力ID相关联的一个或多个SSS构成的SSSB与所述SSSG之间重叠的一个或多个SSS进行监听。
在UE侧的操作也可以结合下文将详细介绍的第二实施例，这种结合的详细实施方式也将在下文详细描述。
再次参考图6，UE的概念性操作流程在S614处结束。
要指出的是，图6所示的UE的操作步骤仅仅是示意性的。在实践中，UE的操作还可以包括一些附加或替代的步骤。例如，已经说明的虚线框中的S610。再例如，如虚线框中的S606所示出的，可选地，UE还可以从基站接收对是否启用按照本公开第一实施例的基于UE的监听能力的SSS切换的通知。例如，可以通过RRC信令接收这种通知。例如，在不进行这种通知步骤的情况下，基站和UE之间可以按照约定默认启用或不启用这种切换。此外，这种通知步骤也可以并非在图6所示的步骤次序处执行。例如，该通知也在S604之前进行，只要UE在恰当的时候能够知道是否启用这种切换即可。
基站与UE之间的交互
以上已经结合附图说明了根据第一实施例的基站以及终端设备的示意性配置以及操作流程。下面，将参考图7说明根据第一实施例，基站与终端设备之间的交互。
首先，UE可以利用任何适用的消息/信令向基站上报其支持的一个或多个监听能力以及相应的监听能力ID。响应于接收到UE的监听能力及相应的监听能力ID，基站为UE针对每个监听能力配置相应的一个或多个SSS，并将每个SSS与监听能力ID进行关联。随后，基站可以向UE发送RRC信令，以指示SSS配置信息，特别地，这种SSS配置信息可以表明SSS与监听能力ID的对应关系。随后，可选地，UE可以向基站发送UAI或MAC CE或任何其他适用的信令，这种信令可以包含与UE期望切换到的一个或多个SSS相关联的一个或多个监听能力ID。自主地或响应于接收到UE期望的监听能力ID，基站可以例如经由DCI消息向UE指示将要监听的一个或多个SSS。
以上已经参考图1-7对本公开的第一实施例进行了详细说明。与现有的为所有类型的UE统一设置进行稀疏或密集监听的SSSG并进行SSSG之间的切换相比，根据本公开的第一实施例可以有利地针对UE来设置基于UE的监听能力的SSS切换的方案，从而实现更细粒度的灵活可调的SSS切换方案。根据本公开的第一实施例，可以基于UE在不同场景下的需求，按照UE能够支持的监听能力来使UE在最恰当的SSS上进行监听。根据本公开的第一实施例，针对每个UE设置SSS切换方案，可以实现对于全网而言的最优SSS设置，例如，可以获得全网UE的最小总功耗。此外，本公开的第一实施例对现有的标准的改动较小，并且具有较强的鲁棒性和可扩展性，从而可以容易地应用于各种垂直应用领域。
第二实施例
根据本公开的第二实施例，基站可以向UE发送包括指示要监听的一个或多个SSS的信息的DCI，其中，所述DCI包括指示DCI格式或大小的信息，并且基站可以向UE配置定时器，从而使得UE在所述一个或多个SSS上，在由定时器规定的预定时间内仅监听符合由DCI中的该信息指示的DCI格式或大小的PDCCH，并且在该定时器规定的预定时间到期之后，恢复监听与所有DCI格式和大小对应的所有候选PDCCH。
下边将结合图8-图12对第二实施例进行详细说明书。
根据本公开的第二实施例控制设备的结构及操作流程
下面将参考图8说明根据本公开的实施例的用于控制设备/基站的电子设备80的概念性结构。
根据第二实施例的电子设备80的整体结构与根据第一实施例的电子设备10的整体结构类似。如图8所示，与图1所示的根据第一实施例的电子设备10类似，电子设备80可以包括处理电路802，并且可选地包括存储器804和通信单元806。存储器804和通信单元806与参考图1描述的存储器104和通信单元106类似，这里不再重复说明。处理电路802与参考图1说明的处理电路102的实现形式类似，即可以是通用处理器的形式，也可以是专用处理电路，这里不再展开说明。
电子设备80的处理电路802可被配置为向UE发送包括指示要监听的一个或多个SSS的信息的DCI，其中，该DCI包括指示DCI格式或大小的信息，并且，电子设备80的处理电路802还可以被配置为向UE配置定时器，从而使得UE在所述一个或多个SSS上， 在由该定时器规定的预定时间内仅监听符合由该DCI中的该信息指示的DCI格式或大小的PDCCH，并且在该定时器规定的预定时间到期之后，恢复监听与所有DCI格式和大小对应的所有候选PDCCH。
在一个实现中，处理电路802可以包括DCI设置单元。例如，该DCI设置单元可以设置要发送给UE的DCI中包括的内容，特别是指示与将要监听的PDCCH相关的DCI格式或大小的信息。例如，这种指示DCI格式或大小的信息可以是指示DCI格式或大小与已经解码的当前DCI的格式或大小属于相同还是不同的DCI格式集的信息。
在一个实现中，处理电路802还可以包括定时器设置单元。例如，该定时器设置单元可以为UE设置一个或多个定时器，特别是与监听符合特定格式或大小的DCI的PDCCH相关联的定时器。
与第一实施例类似地，处理电路802内各个模块的划分并不是必须的，并且这种模块划分也并不一定是固定的。例如，处理电路802还可以包括其他的模块(例如，通信控制模块之类)，也可以不划分模块，而是以处理电路整体来实现电子设备80的功能。
下面将参考图9示出的控制设备/基站的概念性操作流程来详细说明电子设备80所实施的各操作。
基站的操作开始于S902。
在S906处，基站可以生成并向UE发送包括指示要监听的一个或多个SSS的信息的DCI，其中，该DCI包括指示DCI格式或大小的信息。换句话说，基站向UE发送的指示UE要监听的一个或多个SSS的DCI还可以进一步指示UE接下来要监听符合什么样格式或大小的候选PDCCH。
要说明的是，在第二实施例中，包括指示UE要监听的一个或多个SSS的信息以及包括指示DCI格式或大小的信息的这种DCI并不一定是如上文参考第一实施例中说明的指示进行SSS切换的DCI。换句话说，第二实施例中的这种DCI中指示的一个或多个SSS可以是与UE正在监听的一个或多个SSS相同的SSS(即，未指示切换的情况)，也可以是与UE正在监听的SSS不同的SSS(即，指示切换的情况)。例如，第二实施例中的这种DCI可以包括指示SSSG(例如，与当前正在监听的SSSG相同或不同的SSSG)的信息，并且在这种情况下，要监听的一个或多个SSS为构成该SSSG的一个或多个SSS。再例如，第二实施例中的这种DCI可以包括指示按照第一实施例的监听能力ID(例如，与当前正在监听的一个或多个SSS所对应的监听能力ID相同或不同的监听能力ID)的信息，并且在这种情况下，要监听的一个或多个SSS为构成与该监听能力ID相关联的一个或多个SSS。
一般地，在进行盲检测时，UE需要对基站指示的要监听的一个或多个SSS上的所有候选PDCCH尝试进行解码，这些候选PDCCH可以对应于不同的DCI格式或大小。然而，本公开注意到在一些情况下，下行链路上要发送的控制信息可能会集中在一些特定格式或大小的DCI上，因此，可能期望UE仅对符合这些特定格式或大小的候选PDCCH进行监听，而不是监听所有候选PDCCH。因此，可以考虑通过限制DCI格式或大小来限制要监听的候选PDCCH的数量，从而实现监听次数的自适应调整，以进一步降低功耗。
例如，在上下行数据业务量都很大的扩展现实场景(Extended Reality，XR)下，当进入数据调度阶段后，出于节能需求，基站和UE需要在较集中的时间内完成密集的上下行数据业务交互。这种交互涉及的业务较为单一(即通过调度DCI实现的数据调度业务)，并且上下行调度可理解为近乎同时进行，基站同时知道下行调度和上行调度，因此基站可以确定在发送完下行调度之后要发送的下行调度与刚刚发送的上行调度属于相同还是不同的DCI格式集。因此，在发送下行调度时，基站可以向UE指示随后将进行的上行调度的DCI格式或大小(例如，通过指示随后的上行调度与该下行调度属于相同或不同的格式(format)集)，从而仅对符合上行调度的DCI格式或大小的候选PDCCH进行监听，从而降低盲检次数进而满足XR数据快速调度和节能的需求。
在一种实现中，所述指示后续要监听的DCI格式或大小的信息可以是指示DCI格式或大小与已经解码的当前DCI(即，当前接收到的DCI)的格式或大小属于相同还是不同的DCI格式集的信息。在相同的情况下，该信息指示UE在当前接收的DCI中指示的一个或多个SSS上，在由定时器规定的预定时间内仅监听符合已经解码的当前DCI所属的PDCCH；并且在不同的情况下，该信息指示UE在所述一个或多个SSS上，在由定时器规定的预定时间内仅监听不符合已经解码的当前DCI的所属的PDCCH。这里，DCI格式集可以是符合相关标准(例如3GPP标准)的一种或若干DCI格式的集合。例如，DCI格式集可以仅包括单一的DCI格式，也可以包括多个DCI格式(诸如，(DCI 0-2和DCI 1-2)以及(DCI 0-0和DCI 1-0)之类)
例如，在这种实现中，可以在指示要监听的一个或多个SSS的DCI中增加1比特或2比特的信令，或者重用DCI中的1比特或2比特的信息域。例如，当该DCI中的该信令为1时，可以指示UE接下来在预定时间内仅监听符合已解码的当前DCI所属的DCI格式集的候选PDCCH。特别地，当该信令指示的DCI格式集包括多个DCI类型时，该信令表示UE接下来将在预定时间内仅监听符合已解码的当前DCI所属的DCI格式集内包括的多 个DCI类型的候选PDCCH。类似地，当该DCI中的该信令为0时，可以指示UE接下来在预定时间内仅监听不符合已解码的当前DCI的格式或大小所属的DCI格式集的PDCCH。特别地，当该信令指示的DCI格式集包括多个DCI类型时，该信令表示UE接下来将在预定时间内仅监听不符合已解码的当前DCI所属的DCI格式集内包括的任意DCI类型的候选PDCCH。
按照第二实施例，指示DCI格式或大小的信息并不限于上述指示DCI格式或大小与已经解码的当前DCI的格式或大小属于相同还是不同的DCI格式集的信息。基站可以采用任何适当的方式来向UE指示该UE将要按照它来进行监听的DCI格式或大小。例如，基站也可以直接向UE发送将要监听的特定的一个或多个DCI格式。
按照第二实施例，基站可以在任意适当的时间(例如，如图9的虚线框中的S904处)，向UE配置定时器，从而使得UE在由该定时器规定的预定时间内仅监听符合由上述DCI中的上述信息指示的DCI格式或大小的候选PDCCH，并且在该定时器规定的预定时间到期之后，恢复监听与所有DCI格式和大小对应的所有候选PDCCH。
例如，在基站与UE建立通信时，基站可以为UE配置一个通用的定时器，或者多个专用定时器。随后，在盲检测配置期间，例如，如S904所示的在发送指示要监听的一个或多个SSS的DCI之前，或者与发送指示要监听的一个或多个SSS的DCI同时地，向UE指示要使用哪个定时器来规定监听符合特定DCI格式或大小的候选PDCCH的时段。当然，本公开并不限此，基站可以以任何恰当的方式为UE配置定时器，只要UE能够知道监听符合特定DCI格式或大小的候选PDCCH的时段即可。
基站的概念性操作流程在S908处结束。
要指出的是，图9所示的基站的操作步骤仅仅是示意性的。在实践中，基站的操作还可以包括一些附加或替代的步骤。例如，第二实施例也可以与上文说明的第一实施例相结合地实施。下面将对这种结合的实施方式进行详细说明。
在将第一实施例与第二实施例结合实施的情况下，可以在执行基于UE的监听能力的SSS切换时，在向UE指示将要监听的一个或多个SSS的DCI中进一步包括指示DCI格式或大小的信息，并且向UE配置定时器，从而使得UE在将要进行监听的一个或多个SSS上，在由该定时器规定的预定时间内仅监听符合由该DCI中的该信息指示的DCI格式或大小的候选PDCCH，并且在该定时器规定的预定时间到期之后，恢复监听与所有DCI格式和大小对应的所有候选PDCCH。
具体而言，基站可以如在第一实施例中详细说明的那样，从UE接收指示UE支持 的一个或多个监听能力的能力信息和与每个监听能力相关联的监听能力ID；将与所述一个或多个监听能力中的每个监听能力相关联的一个或多个SSS与和该监听能力相关联的监听能力ID进行关联；向UE发送SSS配置信息，其中，该SSS配置信息至少指示与每个SSS相关联的监听能力ID；和向UE发送DCI，该DCI包括第一监听能力ID，从而指示UE将要监听的一个或多个SSS(例如，与第一监听能力ID相关联的一个或多个SSS)。并且如在第二实施例中详细说明的那样，该DCI进一步包括指示DCI格式或大小的信息并且基站还为UE配置定时器，从而使得UE在接收到所述DCI后，在要监听的一个或多个SSS上，在由该定时器规定的预定时间内仅监听符合由该DCI中的该信息指示的DCI格式或大小的候选PDCCH，并且在该定时器规定的预定时间到期之后，恢复监听与所有DCI格式和大小对应的所有候选PDCCH。
要说明的是，第一实施例的具体实施细节与第二实施例的具体实施细节可以进行任意程度的组合。例如，基站向UE发送的指示要监听的一个或多个SSS的DCI可以包括指示监听能力ID的信息、指示SSSG的信息以及指示DCI格式或大小的信息。在这种情况下，UE在接收到该DCI后，在与监听能力ID相关联的一个或多个SSS和SSSG之间重叠的一个或多个SSS上，在预定时间内仅监听符合由该DCI中的该信息指示的DCI格式或大小的候选PDCCH，并且在该定时器规定的预定时间到期之后，恢复监听与所有DCI格式和大小对应的所有候选PDCCH。
要说明的是，基站不一定必须在需要向UE指示要进行SSS切换的定时发送规定即将监听的DCI格式或大小的信息。实际上，基站可以在确定可以通过限制DCI格式或大小来减少候选PDCCH的定时向UE发送指示要监听的DCI格式或大小的信息。在这种情况下，例如，基站可以向UE发送至少包括如下信息的DCI：与UE当前正在监听的一个或多个SSS对应的监听能力ID和/或指示SSSG的信息，以及UE将要按照它来进行监听的特定的DCI格式或大小。
根据本公开第二实施例的终端设备的结构和操作流程
上文详细说明了根据本公开第二实施例的控制设备/基站的示例性结构以及示例性操作。下面，将结合图10-图11说明根据本公开的终端设备/UE的示例性结构以及示例性操作流程。
首先将参考图10说明根据本公开的实施例的用于终端设备/UE的电子设备100的概念性结构。
根据第二实施例的电子设备100的整体结构与根据第一实施例的电子设备50的整体结构类似。如图10所示，与图5所示的根据第一实施例的电子设备50类似，电子设备100可以包括处理电路1002，并且可选地包括存储器1002和通信单元1004。存储器1002和通信单元1004与参考图5描述的存储器504和通信单元506类似，这里不再重复说明。处理电路1002与参考图5说明的处理电路502的实现形式类似，即可以是通用处理器的形式，也可以是专用处理电路，这里不再展开说明。
电子设备100的处理电路1002可以被配置为从基站接收包括指示要监听的一个或多个SSS的信息的DCI，所述DCI包括指示DCI格式或大小的信息。电子设备100的处理电路1002进一步可以被配置为处理由基站配置定时器，并且进行控制以在DCI指示的一个或多个SSS上，在由定时器规定的预定时间内仅监听符合由DCI中的该信息指示的DCI格式或大小的候选PDCCH，并且在定时器规定的预定时间到期之后，恢复监听与所有DCI格式和大小对应的所有候选PDCCH。
处理电路1002还可以被配置为执行进一步地功能，并且可选地可以划分不同的模块以实施相应的功能。例如，在与第一实施例结合实施的情况下，处理电路1002还可以控制向基站发送电子设备100的监听能力及监听能力ID，以及可选地确定期望进行切换，并控制向基站发送与其期望切换到的一个或多个SSS相关联的监听能力ID等。
下面，将参考图11说明根据第二实施例的终端设备/UE的概念性操作流程110。
UE的操作开始于S1102。
在S1106处，UE从基站接收包括指示要监听的一个或多个SSS的信息和指示DCI格式或大小的信息的DCI。例如，如在上文参考基站的操作说明的，所述指示DCI格式或大小的信息可以是指示DCI格式或大小与已经解码的当前DCI(即，当前接收到的DCI)的格式或大小属于相同还是不同的DCI格式集的信息。
响应于接收到该DCI，在S1108处，UE按照该DCI的指示来进行监听。具体而言，UE可以在该DCI所指示的一个或多个SSS上，在预定时间内仅监听符合由该DCI指示的DCI格式或大小的候选PDCCH，并且在预定时间到期之后，恢复监听与所有DCI格式和大小对应的所有候选PDCCH。例如，在DCI包括指示DCI格式或大小与已经解码的所述DCI的格式或大小属于相同还是不同的DCI格式集的信息的情况下，响应于该信息指示相同，UE可以在当前接收的DCI中指示的一个或多个SSS上，在预定时间内仅监听符合已经解码的当前DCI所属的PDCCH；并且响应于该信息指示不同，UE可以在所述一个或多个SSS上，在预定时间内仅监听不符合已经解码的当前DCI的所属的PDCCH。
这里，上述“预定时间”可以是基于基站向UE配置的定时器而确定的。例如，UE可以在任意适当的时间(例如，如图11的虚线框中的S1104处)，从基站接收定时器配置，以便确定监听符合特定格式或大小的DCI的候选PDCCH的时间段。
UE的操作流程在S1110处结束。
要指出的是，图11所示的UE的操作步骤仅仅是示意性的。在实践中，UE的操作还可以包括一些附加或替代的步骤。例如，在上文详细说明的第一实施例与第二实施例结合实施的情况下，UE还可以包括向基站发送监听能力及监听能力ID、接收SSS配置信息以及上报期望的监听能力ID等操作。
基站与UE之间的交互
以上已经结合附图说明了根据第二实施例的基站以及终端设备的示意性配置以及操作流程。下面参考图12简单说明按照第二实施例的UE与基站之间的交互。
如图12所示，首先，基站可以向UE配置定时器。这里，配置定时器可以是指向UE指示要使用先前(例如，在建立通信时)配置的定时器中的特定定时器，从而使UE知道要使用哪个定时器来确定监听符合特定格式或大小的DCI的候选PDCCH的时间段。
随后，基站可以向UE发送DCI。该DCI可以包括指示要监听的一个或多个SSS的信息和指示DCI格式或大小的信息，从而使得UE在该DCI所指示的一个或多个SSS上，在由定时器规定的预定时间内仅监听符合由该DCI指示的DCI格式或大小的候选PDCCH，并且在预定时间到期之后，恢复监听与所有DCI格式和大小对应的所有候选PDCCH。
以上已经参考图8-12对本公开的第二实施例进行了详细说明。根据本公开的第二实施例，有利地是可以通过限制DCI格式或大小来限制要监听的候选PDCCH的数量，从而实现监听次数的自适应调整，以进一步降低功耗。此外，本公开的第二实施例对现有的标准的改动较小，易于实施。
特别地，在第一实施例与第二实施例结合实施的情况下，可以一方面，提供针对UE的基于UE的监听能力的SSS切换，另一方面，可以限制要监听的候选PDCCH的数量，从而能够在按照UE能够支持的监听能力使UE在最恰当的SSS上进行监听的基础上尽可能地减少功耗。
应当理解，根据本公开实施例的机器可读存储介质或程序产品中的机器可执行指令可以被配置为执行与上述设备和方法实施例相应的操作。当参考上述设备和方法实施例 时，机器可读存储介质或程序产品的实施例对于本领域技术人员而言是明晰的，因此不再重复描述。用于承载或包括上述机器可执行指令的机器可读存储介质和程序产品也落在本公开的范围内。这样的存储介质可以包括但不限于软盘、光盘、磁光盘、存储卡、存储棒等等。
另外，应当理解，上述系列处理和设备也可以通过软件和/或固件实现。在通过软件和/或固件实现的情况下，从存储介质或网络向具有专用硬件结构的计算机，例如图13所示的通用个人计算机1300安装构成该软件的程序，该计算机在安装有各种程序时，能够执行各种功能等等。图13是示出作为本公开的实施例中可采用的信息处理设备的个人计算机的示例结构的框图。在一个例子中，该个人计算机可以对应于根据本公开的上述示例性终端设备。
在图13中，中央处理单元(CPU)1301根据只读存储器(ROM)1302中存储的程序或从存储部分1308加载到随机存取存储器(RAM)1303的程序执行各种处理。在RAM 1303中，也根据需要存储当CPU 1301执行各种处理等时所需的数据。

根据需要，驱动器1310也连接到输入/输出接口1305。可拆卸介质1311比如磁盘、光盘、磁光盘、半导体存储器等等根据需要被安装在驱动器1310上，使得从中读出的计算机程序根据需要被安装到存储部分1308中。
在通过软件实现上述系列处理的情况下，从网络比如因特网或存储介质比如可拆卸介质1311安装构成软件的程序。
本领域技术人员应当理解，这种存储介质不局限于图13所示的其中存储有程序、与设备相分离地分发以向用户提供程序的可拆卸介质1311。可拆卸介质1311的例子包含磁盘(包含软盘(注册商标))、光盘(包含光盘只读存储器(CD-ROM)和数字通用盘(DVD))、磁光盘(包含迷你盘(MD)(注册商标))和半导体存储器。或者，存储介质可以是ROM 1302、存储部分1308中包含的硬盘等等，其中存有程序，并且与包含它们的设备一起被分发给用户。

例如，本公开中提到的终端设备在一些示例中也称为用户设备，可以被实现为移动终端(诸如智能电话、平板个人计算机(PC)、笔记本式PC、便携式游戏终端、便携式/加密狗型移动路由器和数字摄像装置)或者车载终端(诸如汽车导航设备)。用户设备还可以被实现为执行机器对机器(M2M)通信的终端(也称为机器类型通信(MTC)终端)。此外，用户设备可以为安装在上述终端中的每个终端上的无线通信模块(诸如包括单个晶片的集成电路模块)。
以下将参照图14至图17描述根据本公开的示例。
