Description

搜索空间配置、确定方法和装置、通信装置和存储介质 技术领域
本公开涉及通信技术领域，具体而言，涉及搜索空间配置方法、搜索空间确定方法、搜索空间配置装置、搜索空间确定装置、通信装置和计算机可读存储介质。
背景技术
在相关技术中，为了解决寻呼paging空检的问题，引入了寻呼提前指示(Paging Early Indication，PEI)，终端根据PEI可以确定是否需要监听寻呼信令，以免浪费资源。
PEI是通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)发送的，PEI对应的PDCCH是在PEI的搜索空间(Search Space，SS)中发送的，PEI SS的频域资源处于系统的初始下行带宽部分(initial DL(Downlink)BWP(Bandwidth Part))内。
在目前的系统中，只存在一个PEI SS，PEI SS对于全部终端而言是共享的，初始下行带宽部分对于全部终端而言也是相同的。但是随着通信技术的发展，引入了不同类型的终端，而为不同类型的终端可以配置不同的初始下行带宽部分，这导致终端难以确定PEI SS处于哪个初始下行带宽部分内。
发明内容
有鉴于此，本公开的实施例提出了搜索空间配置方法、搜索空间确定方法、搜索空间配置装置、搜索空间确定装置、通信装置和计算机可读存储介质，以解决相关技术中的技术问题。
根据本公开实施例的第一方面，提出一种搜索空间配置方法，由网络侧设备执行，所述方法包括：将第一类型终端的寻呼消息提前指示PEI的第一搜索空间，配置在第一带宽部分BWP中或者配置在第二BWP中。
根据本公开实施例的第二方面，提出一种搜索空间确定方法，由第一类型终端执行，所述方法包括：在第一BWP中或者在第二BWP中确定PEI的第一搜索空间。
根据本公开实施例的第三方面，提出一种搜索空间配置装置，所述装置包括：处理模块，被配置为将第一类型终端的寻呼消息提前指示PEI的第一搜索空间，配置在第一带宽部分BWP中或者配置在第二BWP中。
根据本公开实施例的第四方面，提出一种搜索空间确定装置，所述装置包括：处理模块，被配置为在第一BWP中或者在第二BWP中确定PEI的第一搜索空间
根据本公开实施例的第五方面，提出一种通信装置，包括：处理器；用于存储计算机程序的存储器；其中，当所述计算机程序被处理器执行时，实现上述搜索空间配置方法。
根据本公开实施例的第六方面，提出一种通信装置，包括：处理器；用于存储计算机程序的存储器；其中，当所述计算机程序被处理器执行时，实现上述搜索空间确定方法。
根据本公开实施例的第七方面，提出一种计算机可读存储介质，用于存储计算机程序，当所述计算机程序被处理器执行时，实现上述搜索空间配置方法中的步骤。
根据本公开实施例的第八方面，提出一种计算机可读存储介质，用于存储计算机程序，当所述计算机程序被处理器执行时，实现上述搜索空间确定方法中的步骤。
根据本公开的实施例，网络侧设备可以将第一类型终端的PEI的第一搜索空间，配置在第一带宽部分BWP中或者配置在第二BWP中，据此，使得第一类型终端可以明确在第一BWP中确定PEI SS，或者在第二BWP中确定PEI SS，从而准确地确定BWP，进而可以在确定的PEI SS中获取PEI。
在第一类型终端包括RedCap终端的情况下，RedCap终端并不是默认PEI SS配置在默认BWP内，而是可以根据具体情况分析网络侧设备将PEI SS配置在第一BWP内，还是配置在第二BWP内，确保能够在确定的BWP内确定到PEI SS，进而准确地确定PEI SS中的PEI。

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。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和 “该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
出于简洁和便于理解的目的，本文在表征大小关系时，所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说，可以理解：术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义；术语“高于”涵盖了“高于等于”的含义，“低于”也涵盖了“低于等于”的含义。
图1是根据本公开的实施例示出的一种搜索空间配置方法的示意流程图。本实施例所示的搜索空间配置方法可以由网络侧设备执行，所述网络侧设备可以与终端通信，所述网络侧设备包括但不限于4G基站、5G基站、6G基站等通信系统中的基站，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
如图1所示，所述搜索空间配置方法可以包括以下步骤：
在步骤S101中，将第一类型终端的寻呼消息提前指示PEI的第一搜索空间，配置在第一带宽部分BWP中或者配置在第二BWP中。
在一个实施例中，在非连续接收(Discontinuous Reception，DRX)场景下，终端可以在每个DRX周期内的寻呼时机(Paging Occasion，PO)中监听网络侧设备发送的寻呼信令。但是网络侧设备并不一定在每个DRX周期中都会发送寻呼信令，当在某个DRX周期中网络侧设备没有发送寻呼信令，终端在该DRX周期的PO中进行监听，就会造成终端的资源浪费。
图2是根据本公开的实施例示出的一种PO的示意图。
如图2所示，以3个DRX周期为例，每个DRX周期中存在一个PO。在第一个DRX周期和第二个DRX周期中，网络侧设备并没有发送寻呼信令，在第三个DRX周期中，网络侧设备发送寻呼信令。
终端在第一个DRX周期和第二个DRX周期的PO内即使进行监听，也不能监 听到寻呼信令，而在第三个DRX周期的PO内进行监听，才能监听到寻呼信令，进而可以根据寻呼信令中携带的寻呼消息的资源监听寻呼消息(paging message)，例如寻呼消息可以携带在物理下行共享信道(Physical Downlink Shared Channel，PDSCH)中。
可见，当终端在第一个DRX周期和第二个DRX周期的PO内进行监听时，并不能监听到寻呼信令，这会造成终端的资源(例如电量)浪费。
针对这个问题，可以引入PEI来克服，例如在每个DRX周期中可以分别设置一个PEI，网络侧设备通过PEI指示在PEI所在的DRX周期中是否发送寻呼信令。
图3是根据本公开的实施例示出的一种PEI的示意图。
如图3所示，例如在图2所示实施例的基础上，网络侧设备在三个DRX周期中可以分别发送PEI，其中，在第一个DRX周期和第二个DRX周期中的PEI可以指示网络侧设备未在第一个DRX周期和第二个DRX周期中发送寻呼信令，在第三个DRX周期中的PEI可以指示网络侧设备在第三个DRX周期中发送了寻呼信令。
终端根据第一个DRX周期和第二个DRX周期中的PEI，可以确定网络侧设备未发送寻呼信令，根据第三个DRX周期中的PEI，可以确定网络侧设备发送寻呼信令，那么在第一个DRX周期和第二个DRX周期的PO中就不监听寻呼信令，在第三个DRX周期的PO中监听寻呼信令。据此，终端根据PEI，仅在网络侧设备发送寻呼信令的DRX周期的PO中监听寻呼信令，在网络侧设备未发送寻呼信令的DRX周期的PO中不监听寻呼信令，避免了终端的资源浪费。
在一个实施例中，PEI是通过物理下行控制频道PDCCH发送的，PEI对应的PDCCH是在PEI的搜索空间SS中发送的，用于发送PEI SS的资源处于系统的初始下行带宽部分initial DL BWP内。因此，为了获取到PEI，终端需要先确定PEI SS所在的initial DL BWP，然后在确定的initial DL BWP中确定PEI SS，进而在PEI SS中确定PEI。
在一些系统中，只存在一个PEI SS，PEI SS对于全部终端(例如一个小区内的全部终端)而言是共享的，initial DL BWP对于全部终端而言也是相同的。但是随着通信技术的发展，引入了不同类型的终端，而为不同类型的终端可以配置不同的初始下行带宽部分。
例如对于两种类型的终端而言，配置给第一类型终端的initial DL BWP称作第一BWP，配置给第二终端的initial DL BWP称作第二BWP，第一BWP和第二BWP 有所不同。由于存在两个不同的initial DL BWP，这就导致终端难以确定PEI SS处于哪个初始下行带宽部分内。
例如在传统终端legacy UE(或称为non-RedCap UE)的基础上，引入了能力降低(Reduced Capability，RedCap)终端，也称作NR-lite。对于传统终端和RedCap终端，配置的initial DL BWP可以相同也可以不同，例如对于传统终端而言，仍然按照传统方式配置initial DL BWP，而对于RedCap终端则配置独立separate initial DL BWP，RedCap终端的separate initial DL BWP与传统终端的initial DL BWP不同；同时，RedCap终端也可以使用与legacy UE相同的initial DL BWP。对于RedCap终端而言，需要准确确定PEI SS处于哪个initial DL BWP内。
根据本公开的实施例，网络侧设备可以将第一类型终端的PEI的第一搜索空间，配置在第一带宽部分BWP中或者配置在第二BWP中，据此，使得第一类型终端可以明确在第一BWP中确定PEI SS，或者在第二BWP中确定PEI SS，从而准确地确定BWP，进而可以在确定的PEI SS中获取PEI。
在一个实施例中，所述第一类型终端在所述第一BWP监测寻呼消息。
在一个实施例中，所述第一BWP包括所述第一类型终端的初始下行带宽部分initial DL BWP；和/或所述第二BWP包括所述第二类型终端的initial DL BWP。
在一个实施例中，所述第一类型终端包括能力降低RedCap终端；和/或所述第二类型终端包括传统legacy终端。
在一个实施例中，针对RedCap终端和传统终端这两种类型终端而言，可以分别配置initial DL BWP，例如对于RedCap终端配置的initial DL BWP为separate initial DL BWP，简称为第一BWP，对于传统终端配置的initial DL BWP简称为第二BWP。由于对于两种类型的终端而言，initial DL BWP有所不同，网络侧设备可能将对应于第一类型UE的PEI SS配置在第一BWP内，也可能配置在第二BWP内。这是由于，第一类型UE既可以使用第一类型UE专用的separate initial DL BWP，也可以使用与legacy UE相同的initial DL BWP。
若RedCap终端默认PEI SS配置在第一BWP中，传统终端默认PEI SS配置在第二BWP中，那么当网络侧设备对于RedCap终端将PEI SS配置在第二BWP中时，RedCap终端在第一BWP中就无法确定到PEI SS，这不仅会导致RedCap终端无法根据PEI SS确定PEI，还浪费了终端的资源。
若RedCap终端和传统终端都默认PEI SS配置在第二BWP中，那么当网络侧设备对于RedCap终端将PEI SS配置在第一BWP中时，RedCap终端在第二BWP中就无法确定到PEI SS，这不仅会导致RedCap终端无法根据PEI SS确定PEI，还浪费了终端的资源。
可见，当终端默认PEI SS配置在默认BWP内时，将可能存在终端无法确定到PEI SS，进而无法根据PEI SS确定PEI的问题。
根据本公开的实施例，可以根据具体情况分析网络侧设备将PEI SS配置在第一BWP内，还是配置在第二BWP内，确保能够在确定的BWP内确定到PEI SS，进而准确地确定PEI SS中的PEI。
图4是根据本公开的实施例示出的另一种搜索空间配置方法的示意流程图。如图4所示，所述将第一类型终端的寻呼消息提前指示PEI的第一搜索空间，配置在第一带宽部分BWP中或者配置在第二BWP中包括：
在步骤S401中，根据预定义规则将所述第一搜索空间，配置在第一BWP中或者配置在第二BWP中。
在一个实施例中，网络侧设备可以根据预定义规则将第一类型终端的PEI的第一搜索空间配置在BWP中或者配置在第二BWP中。需要说明的是，预定义规则对于网络侧设备和终端(例如第一类型终端和/或第二类型终端)而言都是已知，例如是基于协议约定确定的，也可以是网络侧设备确定后告知终端的(例如，通过系统信息告知终端)，还可以是UE确定后告知网络侧设备(例如，UE上报给网络侧设备其所在的带宽部分是第一BWP还是第二BWP)。
在本公开实施例中，该预定义规则还可以为：在第一类型终端的初始下行BWP(initial DL BWP)上发送第一搜索空间。示例性的，网络侧设备可以通过MIB指示第一类型终端的初始下行BWP(initial DL BWP)，且所述MIB还用于指示所述UE在initial DL BWP中接收用于发送PEI的搜索空间SS。在上述实施例中，MIB指示第一类型终端的初始下行BWP既可以是第一BWP，也可以是第二BWP。当然，还可以通过其他消息指示，本公开实施例中并不对此做出限定。
进而第一类型终端也可以根据预定义规则或通信协议确定网络侧设备将第一搜索空间配置在了第一BWP中还是配置在了第二BWP中。例如在确定网络侧设备将第一搜索空间配置在了第一BWP中时，第一类型终端可以在第一BWP中确定第一搜 索空间，从而确保能够成功确定到第一搜索空间，进而在第一搜索空间中确定PEI；例如在确定网络侧设备将第一搜索空间配置在了第二BWP中时，第一类型终端可以在第二BWP中确定第一搜索空间，从而确保能够成功确定到第一搜索空间，进而在第一搜索空间中确定PEI。
图5是根据本公开的实施例示出的又一种搜索空间配置方法的示意流程图。如图5所示，所述根据预定义规则将所述第一搜索空间，配置在第一BWP中或者配置在第二BWP中包括：
在步骤S501中，确定所述第一类型终端监测的寻呼信令的搜索空间所在的目标BWP；
在步骤S502中，将所述第一搜索空间，配置在所述目标BWP中。
在一个实施例中，预定义规则可以是将第一搜索空间与第一类型终端监测的paging的搜索空间配置在相同的BWP，那么可以先确定终端监测的paging的搜索空间所在的BWP，例如称作目标BWP，目标BWP可以包括第一BWP。进而可以将第一搜索空间配置在目标BWP中。
相应地，第一类型终端可以先确定监测的paging的搜索空间所在的目标BWP，然后在目标BWP中确定第一搜索空间。
据此，终端在目标BWP中确定第一搜索空间后，可以在第一搜索空间中确定PEI，并根据确定的PEI确定是否需要在对应的DRX周期中监测寻呼信令，而关于寻呼信令的搜索空间也可以在目标BWP中确定。在此过程中，终端确定第一搜索空间和确定寻呼信令的搜索空间都是在相同BWP上进行的，从而无需切换BWP，有利于简化操作。
在一个实施例中，所述方法还包括：
将所述第二类型终端的PEI的第二搜索空间，配置在所述第二BWP中。
在网络侧设备在目标BWP，例如第一BWP中，为第一类型终端配置第一搜索空间的基础上，网络侧设备还可以将第二类型终端的PEI的第二搜索空间配置在第二BWP上。也即网络侧设备配置至少一个的PEI SS，并发送至少一个PEI SS的配置。
在一个实施例中，第一搜索空间的配置信息(可以称为第一配置)和所述第二搜索空间的配置信息(可以称为第二配置)可以相同，也可以不同，例如可以部分相 同(例如频域资源存在部分重叠)，也可以全部不同(例如频域资源不存在重叠)，具体可以根据需要进行配置。
在本公开的所有实施例中，第一类型终端对应的第一搜索空间可以配置在第一BWP中，也可以配置在第二BWP中；在一些可能的实现方式中，第一搜索空间配置在第一BWP中时和配置在第二BWP中时，该第一搜索空间的配置参数可以相同，也可以不同。其中，第一搜索空间的配置参数可以相同是指，该第一搜索空间在第一BWP和第二BWP的相对资源位置(例如相对频域位置和/或相对频域位置)可以相同(例如在第一BWP与第二BWP部分重叠、第一BWP在第二BWP之内、第二BWP在第一BWP之内等情况下)，也可以不同。
图6是根据本公开的实施例示出的又一种搜索空间配置方法的示意流程图。如图6所示，所述根据预定义规则将所述第一搜索空间，配置在第一BWP中或者配置在第二BWP中包括：
在步骤S601中，将所述第一搜索空间，配置在第二BWP中。
在一个实施例中，预定义规则可以是将第一搜索空间配置在第二BWP中，那么网络侧设备可以将第一搜索空间配置在目标BWP中。相应地，第一类型终端可以在第二BWP中确定第一搜索空间。
据此，由于第二类型终端的PEI的第二搜索空间也是配置在第二BWP中的，因此对于网络侧设备而言，可以将两种类型终端的PEI SS都配置在第二BWP中，而无需分别配置在不同的BWP中，有利于简化网络侧设备的配置过程。在本公开实施中，对应于第一类型终端的第一搜索空间和对应于第二类型终端，可以采用相同的搜索空间，也可以采用不同的搜索空间，在此不再赘述。
在一个实施例中，所述方法还包括：
通过广播消息向所述第一类型终端指示所述第二BWP的配置信息。
由于第一BWP是配置给第一类型终端的initial DL BWP，第二BWP是配置给第二类型终端的initial DL BWP，所以对于第一类型终端而言并不知道第二BWP。因此，网络侧设备在将第一搜索空间配置在第二BWP中时，需要先通过广播消息向第一类型终端指示第二BWP的配置信息，以使第一类型终端能够确定第二BWP，进而才能在第二BWP中确定第一搜索空间。例如，第二BWP的配置信息包括第二BWP的编号；此时UE可以根据预先配置的每一BWP的编号与配置参数之间的对应关系， 确定哪一个BWP为第二BWP。又例如，第二BWP的配置信息包括以下的至少一种：第二BWP的时域位置、第二BWP的频域位置信息；此时UE可以根据第二BWP的配置信息确定第二BWP。当然，这些都是举例说明，本公开实施中可以以任何可能的方式为第一类型终端指示第二BWP，在此不再赘述。
在一个实施例中，所述广播消息包括以下至少之一：
系统信息、寻呼信令。
网络侧设备可以通过系统信息向第一类型终端指示第二BWP的配置信息，也可以通过寻呼信令向第一类型终端指示第二BWP的配置信息。其中，在通过系统信息向第一类型终端指示第二BWP的配置信息时，系统信息可以是主系统信息块(Master Information Block，MIB)，也可以是系统信息块(System Information Blocks，SIB)，例如SIB1。具体可以由网络侧设备根据需要确定。
即，网络侧设备可以通过MIB指示第一类型终端的初始下行BWP(initial DL BWP)，且所述MIB还用于指示所述UE在initial DL BWP中接收用于发送PEI的搜索空间SS。在上述实施例中，MIB指示第一类型终端的初始下行BWP既可以是第一BWP，也可以是第二BWP。当然，还可以通过其他消息指示，本公开实施例中并不对此做出限定。
在一个实施例中，所述第一搜索空间和所述第二类型终端的PEI的第二搜索空间相同。
网络侧设备在将第一搜索空间配置在第二BWP中时，由于第二类型终端的PEI的第二搜索空间也是配置在第二BWP中的，因此，可以将第一搜索空间和第二搜索空间采用相同的配置信息，据此，有利于简化网络侧设备的配置操作。
需要说明的是，在将第一搜索空间和第二搜索空间都配置在第二BWP中时，网络侧设备也可以选择将第一搜索空间和第二搜索空间采用不相同的配置信息。
在一个实施例中，所述第一类型终端检测的PEI在所述第一搜索空间中对应的资源和所述第二类型终端监测的PEI在所述第二搜索空间中对应的资源相同。即，针对第一类型终端和第二类型终端，在第二BWP中对应的PEI为同一个PEI。
在第一搜索空间和第二搜索空间相同的情况下，网络侧设备进一步可以将第一类型终端检测的PEI在第一搜索空间中对应的资源，和第二类型终端监测的PEI在第二搜索空间中对应的资源配置的相同，据此，有利于进一步简化网络侧设备的配置操 作。
需要说明的是，在第一搜索空间和第二搜索空间采用相同的配置信息的情况下，网络侧设备也可以选择将第一类型终端检测的PEI在第一搜索空间中对应的资源，和第二类型终端监测的PEI在第二搜索空间中对应的资源配置的不同。
图7是根据本公开的实施例示出的又一种搜索空间配置方法的示意流程图。如图7所示，所述方法还包括：
在步骤S701中，响应于将所述第一搜索空间配置在所述第一BWP中，向所述第一类型终端发送第一配置信息，所述第一配置信息用于指示所述第一搜索空间配置在所述第一BWP中。
或，所述方法还包括：
在步骤S702中，响应于将所述第一搜索空间配置在所述第二BWP中，向所述第一类型终端发送第二配置信息，所述第二配置信息用于指示所述第二搜索空间配置在所述第二BWP中
在一个实施例中，网络侧设备也可以不根据预定义规则将第一搜索空间配置在第一BWP中或者配置在第二BWP中，而是根据实际需要选择将将第一搜索空间配置在第一BWP中或者配置在第二BWP中，并向第一类型终端发送配置信息，以指示第一类型终端第一搜索空间被配置在了哪个BWP。
例如，网络侧设备将第一搜索空间配置在第一BWP中，可以向第一类型终端发送第一配置信息，用于指示第一搜索空间配置在第一BWP中。那么终端根据第一配置信息，可以在第一BWP中确定第一搜索空间。又例如，网络侧设备在第一搜索空间配置在第二BWP中，可以向第一类型终端发送第二配置信息，用于指示第一搜索空间配置在第二BWP中。那么终端根据第二配置信息，可以在第二BWP中确定第一搜索空间。在上述实施例中，第一配置信息和第二配置信息可以为控制信令的一个字段域，其不同的取值用于指示第一搜索空间配置在第一BWP中或第二BWP中，也就是显性指示。当然，第一配置信息和第二配置信息也可以为不同的控制信令，或为同一控制信令的不同字段域。在上述实施例中，第一配置信息和第二配置信息可以为隐性指示方式，例如：采用不同的编码方式来指示第一搜索空间配置在第一BWP中或第二BWP中，或采用不同的预设信息来指示第一搜索空间配置在第一BWP中或第二BWP中(例如，当UE接收到某预设信息时，就可以知道第一搜索空间配置在第一 BWP中或第二BWP中)。
图8是根据本公开的实施例示出的一种搜索空间确定方法的示意流程图。本实施例所示的搜索空间确定方法可以由第一类型终端执行，所述第一类型终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置，例如所述第一类型终端包括能力降低(Reduced capability，RedCap)终端。所述第一类型终端可以与网络侧设备通信，所述网络侧设备包括但不限于4G、5G、6G等通信系统中的网络侧设备，例如基站、核心网等。
如图8所示，所述搜索空间确定方法可以包括以下步骤：
在步骤S801中，在第一BWP中或者在第二BWP中确定PEI的第一搜索空间。
在一个实施例中，在非连续接收(Discontinuous Reception，DRX)场景下，终端可以在每个DRX周期内的寻呼时机(Paging Occasion，PO)中监听网络侧设备发送的寻呼信令。但是网络侧设备并不一定在每个DRX周期中都会发送寻呼信令，当在某个DRX周期中网络侧设备没有发送寻呼信令，终端在该DRX周期的PO中进行监听，就会造成终端的资源浪费。
如图2所示为3个DRX周期的举例说明；如图3所示，例如在图2所示实施例的基础上，网络侧设备在三个DRX周期中可以分别发送PEI为例，
根据本公开的实施例，网络侧设备可以将第一类型终端的PEI的第一搜索空间，配置在第一带宽部分BWP中或者配置在第二BWP中，据此，使得第一类型终端可以明确在第一BWP中确定PEI SS，或者在第二BWP中确定PEI SS，从而准确地确定BWP，进而可以在确定的PEI SS中获取PEI。
在一个实施例中，所述第一类型终端在所述第一BWP监测寻呼消息。
在一个实施例中，所述第一BWP包括所述第一类型终端的初始下行带宽部分initial DL BWP；和/或所述第二BWP包括所述第二类型终端的initial DL BWP。
在一个实施例中，所述第一类型终端包括能力降低RedCap终端；和/或所述第二类型终端包括传统legacy终端。
在一个实施例中，针对RedCap终端和传统终端这两种类型终端而言，可以分别配置initial DL BWP，例如对于RedCap终端配置的initial DL BWP为separate initial DL BWP，简称为第一BWP，对于传统终端配置的initial DL BWP简称为第二BWP。 由于对于两种类型的终端而言，initial DL BWP有所不同，网络侧设备可能将PEI SS配置在第一BWP内，也可能配置在第二BWP内。
若RedCap终端默认PEI SS配置在第一BWP中，传统终端默认PEI SS配置在第二BWP中，那么当网络侧设备对于RedCap终端将PEI SS配置在第二BWP中时，RedCap终端在第一BWP中就无法确定到PEI SS，这不仅会导致RedCap终端无法根据PEI SS确定PEI，还浪费了终端的资源。
若RedCap终端和传统终端都默认PEI SS配置在第二BWP中，那么当网络侧设备对于RedCap终端将PEI SS配置在第一BWP中时，RedCap终端在第二BWP中就无法确定到PEI SS，这不仅会导致RedCap终端无法根据PEI SS确定PEI，还浪费了终端的资源。
可见，当终端默认PEI SS配置在默认BWP内时，将可能存在终端无法确定到PEI SS，进而无法根据PEI SS确定PEI的问题。
根据本公开的实施例，以根据具体情况分析网络侧设备将PEI SS配置在第一BWP内，还是配置在第二BWP内，确保能够在确定的BWP内确定到PEI SS，进而准确地确定PEI SS中的PEI。
图9是根据本公开的实施例示出的另一种搜索空间确定方法的示意流程图。如图9所示，所述在第一BWP中或者在第二BWP中确定PEI的第一搜索空间包括：
在步骤S901中，根据网络侧设备发送的配置信息在第一BWP中或者配置在第二BWP中确定所述第一搜索空间。
在一个实施例中，所述根据网络侧设备发送的配置信息在第一BWP中或者在第二BWP中确定PEI的第一搜索空间包括：
响应于接收到网络侧设备发送的第一配置信息，在所述第一BWP中确定所述第一搜索空间；或者
响应于接收到网络侧设备发送的第二配置信息，在所述第二BWP中确定所述第一搜索空间。
在一个实施例中，网络侧设备可以根据实际需要选择将将第一搜索空间配置在第一BWP中或者配置在第二BWP中，并向第一类型终端发送配置信息，以指示第一类型终端第一搜索空间被配置在了哪个BWP。
例如网络侧设备在将第一搜索空间配置在第一BWP中时，可以向第一类型终端发送第一配置信息，用于指示第一搜索空间配置在第一BWP中。那么终端根据第一配置信息，可以在第一BWP中确定第一搜索空间。
例如网络侧设备在将第一搜索空间配置在第二BWP中时，可以向第一类型终端发送第二配置信息，用于指示第一搜索空间配置在第二BWP中。那么终端根据第二配置信息，可以在第二BWP中确定第一搜索空间。
图10是根据本公开的实施例示出的又一种搜索空间确定方法的示意流程图。如图10所示，所述在第一BWP中或者在第二BWP中确定PEI的第一搜索空间包括：
在步骤S1001中，根据预定义规则在第一BWP中或者配置在第二BWP中确定所述第一搜索空间。
在一个实施例中，网络侧设备可以根据预定义规则或是通信协议，将第一类型终端的PEI的第一搜索空间配置在BWP中或者配置在第二BWP中。需要说明的是，预定义规则对于网络侧设备和终端(例如第一类型终端和/或第二类型终端)而言都是已知，例如是基于协议约定确定的，也可以是网络侧设备确定后告知终端的(例如，通过系统信息告知终端)，还可以是UE确定后告知网络侧设备(例如，UE上报给网络侧设备其所在的带宽部分是第一BWP还是第二BWP，以指示UE在对应的BWP上发送用于传输PEI的搜索空间SS)。
在本公开实施例中，该预定义规则还可以为：在第一类型终端的初始下行BWP(initial DL BWP)上发送第一搜索空间。示例性的，网络侧设备可以通过MIB指示第一类型终端的初始下行BWP(initial DL BWP)，且所述MIB还用于指示所述UE在initial DL BWP中接收用于发送PEI的搜索空间SS。在上述实施例中，MIB指示第一类型终端的初始下行BWP既可以是第一BWP，也可以是第二BWP。当然，还可以通过其他消息指示，本公开实施例中并不对此做出限定。
进而第一类型终端也可以根据预定义规则确定网络侧设备将第一搜索空间配置在了第一BWP中还是配置在了第二BWP中。例如在确定网络侧设备将第一搜索空间配置在了第一BWP中时，第一类型终端可以在第一BWP中确定第一搜索空间，从而确保能够成功确定到第一搜索空间，进而在第一搜索空间中确定PEI；例如在确定网络侧设备将第一搜索空间配置在了第二BWP中时，第一类型终端可以在第二BWP中确定第一搜索空间，从而确保能够成功确定到第一搜索空间，进而在第一搜索空间 中确定PEI。
图11是根据本公开的实施例示出的又一种搜索空间确定方法的示意流程图。如图11所示，所述根据预定义规则在第一BWP中或者配置在第二BWP中确定所述第一搜索空间包括：
在步骤S1101中，确定监测的寻呼信令的搜索空间所在的目标BWP；
在步骤S1102中，在所述目标BWP中确定所述第一搜索空间。
在一个实施例中，预定义规则可以是将第一搜索空间与第一类型终端监测的paging的搜索空间配置在相同的BWP，那么可以先确定终端监测的paging的搜索空间所在的BWP，例如称作目标BWP，目标BWP可以包括第一BWP。进而可以将第一搜索空间配置在目标BWP中。
相应地，第一类型终端可以先确定监测的paging的搜索空间所在的目标BWP，然后在目标BWP中确定第一搜索空间。
据此，终端在目标BWP中确定第一搜索空间后，可以在第一搜索空间中确定PEI，并根据确定的PEI确定是否需要在对应的DRX周期中监测寻呼信令，而关于寻呼信令的搜索空间也可以在目标BWP中确定。在此过程中，终端确定第一搜索空间和确定寻呼信令的搜索空间都是在相同BWP上进行的，从而无需切换BWP，有利于简化操作。
图12是根据本公开的实施例示出的又一种搜索空间确定方法的示意流程图。如图12所示，所述根据预定义规则在第一BWP中或者配置在第二BWP中确定所述第一搜索空间包括：
在步骤S1201中，在所述第二BWP中确定所述第一搜索空间。
在一个实施例中，预定义规则可以是将第一搜索空间配置在第二BWP中，那么网络侧设备可以将第一搜索空间配置在目标BWP中。相应地，第一类型终端可以在第二BWP中确定第一搜索空间。
据此，由于第二类型终端的PEI的第二搜索空间也是配置在第二BWP中的，因此对于网络侧设备而言，可以将两种类型终端的PEI SS都配置在第二BWP中，而无需分别配置在不同的BWP中，有利于简化网络侧设备的配置过程。
在一个实施例中，所述方法还包括：
根据所述网络侧设备发送的广播消息确定所述第二BWP。
由于第一BWP是配置给第一类型终端的initial DL BWP，第二BWP是配置给第二类型终端的initial DL BWP，所以对于第一类型终端而言并不知道第二BWP的配置参数。因此，网络侧设备在将第一搜索空间配置在第二BWP中时，需要先通过广播消息向第一类型终端指示第二BWP，以使第一类型终端能够确定第二BWP，进而才能在第二BWP中确定第一搜索空间。
在一个实施例中，所述广播消息包括以下至少之一：
系统信息、寻呼信令。
网络侧设备可以通过系统信息向第一类型终端指示第二BWP，也可以通过寻呼信令向第一类型终端指示第二BWP。其中，在通过系统信息向第一类型终端指示第二BWP时，系统信息可以是主系统信息块(Master Information Block，MIB)，也可以是系统信息块(System Information Blocks，SIB)，例如SIB1。具体可以由网络侧设备根据需要选择。
图13是根据本公开的实施例示出的又一种搜索空间确定方法的示意流程图。如图13所示，所述在所述第二BWP中确定所述第一搜索空间包括：
在步骤S1301中，在预设时刻从所述第一BWP切换到所述第二BWP，在所述第二BWP中监测所述第一搜索空间。
在一个实施例中，对于第一类型终端而言，第一BWP是网络侧设备配置的initial DL BWP，因此，第一类型终端一般默认会在initial DL BWP与网络侧设备通信。那么当需要在第二BWP上检测PEI SS时，就需要从第一BWP切换到第二BWP，进而在第二BWP中监测第一搜索空间。
其中，从第一BWP切换到第二BWP的预设时刻，可以是网络侧配置的，也可以是基于协议约定确定的。
图14是根据本公开的实施例示出的又一种搜索空间确定方法的示意流程图。如图14所示，所述方法还包括：
在步骤S1401中，在所述第二BWP中监测所述第一搜索空间后的预设时长内，从所述第二BWP切换到所述第一BWP。
在一个实施例中，对于第一类型终端而言，第一BWP是网络侧设备配置的 initial DL BWP，因此，第一类型终端大多数情况下会在initial DL BWP与网络侧设备通信。那么当第一类型终端在第二BWP中完成监测第一搜索空间后，可以从第二BWP切换到第一BWP，以继续与网络侧设备通信。
其中，第一类型终端可以是在第二BWP中监测第一搜索空间后的预设时长内，才从第二BWP切换到第一BWP。预设时长可以是网络侧配置的，也可以是基于协议约定确定的。
例如预设时长可以为0，那么第一类型终端在第二BWP中监测第一搜索空间后，立即从第二BWP切换到第一BWP；例如预设时长可以大于0(例如在第一BWP繁忙的下)，那么第一类型终端在第二BWP中监测第一搜索空间后，可以继续在第二BWP上与网络侧设备通信一段时间，然后才从第二BWP切换到第一BWP。
在一个实施例中，所述第一搜索空间中的PEI对应的第一时域资源，到需要监测的寻呼消息对应的第二时域资源之间的时长大于预设数目的时域单元。
第一类型终端无论在第一BWP内，还是在第二BWP内，第一搜索空间中的PEI对应的第一时域资源到需要监测的寻呼消息对应的第二时域资之间的时长，需要大于预设数目的时域单元，以确保在预设数目的时域单元内，第一类型终端能够完成对PEI的解析，进而根据PEI确定在对应DRX的PO中是否需要监测寻呼信令。
其中，预设数目和时域单元(例如时域符号(例如正交频分复用符号)、时隙slot)可以是网络侧设备配置的，也可以是协议约定的。
需要说明的是，本公开实施例中网络设备的具体实施方式可以是与终端设备的具体实施方式相对应，因此相对应的内容，不再一一重复赘述。
与前述的搜索空间配置方法和搜索空间确定方法的实施例相对应，本公开还提供了搜索空间配置装置和搜索空间确定装置的实施例。
图15是根据本公开的实施例示出的一种搜索空间配置装置的示意框图。本实施例所示的搜索空间配置装置可以适用于网络侧设备，所述网络侧设备可以与终端通信，所述网络侧设备包括但不限于4G基站、5G基站、6G基站等通信系统中的基站，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
如图15所示，所述搜索空间配置装置可以包括：
处理模块1501，被配置为将第一类型终端的寻呼消息提前指示PEI的第一搜索空间，配置在第一带宽部分BWP中或者配置在第二BWP中。
在一个实施例中，所述第一类型终端在所述第一BWP监测寻呼消息。
在一个实施例中，所述第一BWP包括所述第一类型终端的初始下行带宽部分initial DL BWP；和/或所述第二BWP包括所述第二类型终端的initial DL BWP。
