Description

频段指示、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，涉及频段指示方法、频段确定方法、频段指示装置、频段确定装置、通信装置和计算机可读存储介质。
背景技术
随着通信技术的发展，基站与终端可以在越来越多的频段通信，例如在5G中，已经将通信频段拓展到了FR1和FR2频段。
但是目前基站指示给终端的用于通信的频段存在一些限制，例如一般情况下基站与终端通信所用的频段都是一段连续的频段，或者多个连续的频段，也即通过多个频段通信，但是多个频段是相连的，这可能导致针对某些频段通信受限。
发明内容
有鉴于此，本公开的实施例提出了频段指示方法、频段确定方法、频段指示装置、频段确定装置、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，提出一种频段指示方法，由基站执行，所述方法包括：向终端发送频段指示信息，用于指示所述终端在聚合频段与所述基站通信；其中，所述聚合频段具有新的频段标号，且包括多个子频段，所述多个子频段中至少两个相邻的子频段不连续。
根据本公开实施例的第二方面，提出一种频段确定方法，由终端执行，所述方法包括：接收基站发送的频段指示信息；根据所述频段指示信息确定在聚合频段与所述基站通信，其中，所述聚合频段具有新的频段标号，且包括多个子频段，所述多个子频段中至少两个相邻的子频段不连续。

根据本公开实施例的第六方面，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，实现上述频段确定方法中的步骤。
根据本公开的实施例，基站确定多个子频段，多个子频段中至少两个相邻的子频段不连续。进而基站可以将多个子频段作为一个聚合频段指示给终端，从而使得多个子频段作为一个聚合频段的带宽能够满足大多数业务的需要，使得子频段在自身带宽较小，又与其他子频段不连续的情况下，也能够得到有效的利用。

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频段指示方法的示意流程图。本实施例所示的频段指示方法可以由基站执行，所述基站包括但不限于4G基站、5G基站、6G基站等通信系统中的基站。所述基站可以与作为用户设备的终端进行通信，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，所述频段指示方法可以包括以下步骤：
在步骤S101中，向终端发送频段指示信息，用于指示所述终端在聚合频段与所述基站通信；
其中，所述聚合频段具有新的频段标号，且包括多个子频段，所述多个子频段中至少两个相邻的子频段不连续。
在一个实施例中，在通信频段上可能存在一些零散的频段，这些频段并不连续，并且每个频段的带宽较小，例如在1GHz左右存在一些零散的频段被重耕给5G系统，这些频段的带宽在30M左右。这些频段单独使用难以满足5G通信某些业务场景的需要，例如在进行eMBB(Enhanced Mobile Broadband，增强移动宽带)业务时，所需带宽要达到100M。
根据本公开的实施例，基站可以确定多个子频段，多个子频段中至少两个相邻的子频段不连续，例如多个子频段中有两个相邻的子频段之间不连续，例如多个子频段中的每个子频段之间都不连续，例如部分子频段之间连续且部分子频段之间不连续。进而基站可以将多个子频段作为一个聚合频段指示给终端，从而使得多个子频段作为一个聚合频段的带宽能够满足大多数业务的需要，使得子频段在自身带宽较小，又与其他子频段不连续的情况下，也能够得到有效的利用。在本公开的所有实施例中，两个相邻的子频段不连续是指，两个相邻的子频段之间具有间隙，即两个子频段之间在频率上不连续。
需要说明的是，所述子频段包括但不限于重耕给5G的零散频段。聚合频段中的每个子频段在聚合之前是独立的频段，聚合后得到的聚合频段作为一个新的频段，具有新的频段标号，不使用目前已有频段的标号。即：聚合频段的标识为唯一的标识，与已有的标识不同。
在一个实施例中，所述多个子频段包括时分双工(Time Division Duplexing，TDD)子频段和/或频分双工(Frequency Division Duplexing，FDD)子频段。
若聚合频段中的多个子频段为时分双工子频段，终端可以按照时分双工的方式在聚合频段与基站通信；若聚合频段中的多个子频段为频分双工子频段，终端可以按照频分双工的方式在聚合频段与基站通信。
若聚合频段中一部分子频段为时分双工子频段，另一部分子频段为频分双工子频段，那么可以包括以下两种情况：时分双工子频段可以为上行子频段，频分双工子频段为下行子频段；时分双工子频段可以为下行子频段，频分双工子频段为上行子频 段。
图2是根据本公开的实施例示出的另一种频段指示方法的示意流程图。如图2所示，所述方法还包括：
在步骤S201中，向所述终端发送至少一个带宽部分BWP的配置信息，用于配置所述BWP工作于所述聚合频段内，以及每个所述BWP对应的带宽。
在一个实施例中，基站还可以向终端发送配置信息，来为终端在聚合频段内配置至少一个BWP，以及配置每个BWP对应的带宽。终端根据配置信息可以在聚合频段内确定至少一个BWP，并确定每个BWP对应的带宽。
在本公开实施例中，该聚合频段可以为根据步骤101得到的聚合频段，也可以是根据任何可能的方式得到的聚合频段，在此不进行限定。
在一个实施例中，所述至少一个BWP包括1个至4个BWP，也即基站可以在在聚合频段内至少配置一个BWP，至多配置4个BWP，这与目前在频段内配置BWP的数量是相同的，可以减少对已有规则的修改。
图3是根据本公开的实施例示出的一种聚合频段内BWP的示意图。如图3所示，所述BWP对应的带宽包括以下至少之一：
一个完整的子频段、一个子频段中的部分带宽、多个完整的子频段以及多个完整的子频段之间的间隙、多个子频段中的部分带宽以及多个子频段之间的间隙。
在一个实施例中，如图3所示，例如聚合频段包括3个子频段f1、f2和f3，其中f1和f3的带宽为30M，f2的带宽为40M，那么聚合频段的带宽为100M。相邻的两个带宽之间存在间隙gap，例如图3所示的两个间隙的带宽相等，均为10M，间隙为不可用(是指针对某个通信系统不可用)的带宽，例如f1、f2和f3被重耕为5G系统，但是间隙并没有被重耕给5G系统，那么间隙在5G系统中就是不可用的。
以为终端在聚合频段配置4个BWP为例，例如BWP1可以对应子频段f1中的部分带宽，BWP2对应完整的子频段f2，BWP3对应两个子频段f2和f3中的部分带宽以及f2和f3之间的间隙，BWP4对应f1、f2、f3这三个完整的子频段，以及这三个子频段之间的两个间隙。
需要说明的是，以上4个BWP对应的带宽只是为了相对全面地表达与子频段的对应关系，具体BWP在聚合频段中的情况并不限于图3所示的实施例，可以根据 需要设置。
在一个实施例中，所述方法还包括：
在初始BWP上发送广播信道(Physical Broadcast Channel，PBCH)和/或同步信号块(Synchronization Signal Block，SSB)；
其中，所述初始BWP对应一个完整的子频段或一个子频段中的部分带宽。
基站可以在配置给终端的带宽部分中选一个带宽部分作为初始(initial)BWP，进而可以在初始BWP上发送广播信道，也可以在初始BWP上发送同步信号块(其中可以包括同步信号和广播信道)。
由于基站在初始BWP上发送广播信道和/或SSB时，一般还没有向终端发送上述配置信息，那么终端尚未确定聚合频段内的带宽部分BWP，但是终端已经确定了上述聚合频段，所以终端可以在聚合频段中进行搜索，以大致确定初始BWP。
在这种情况下，由于间隙对应带宽是不可用的，所以终端一般不会在间隙上进行搜索，因此基站选择初始BWP时，可以优先选择不包含间隙的BWP作为初始BWP，例如初始BWP对应一个完整的子频段或一个子频段中的部分带宽，以便终端搜索到初始BWP。
在一个实施例中，所述初始BWP还对应多个完整的子频段以及多个完整的子频段之间的间隙、多个子频段中的部分带宽以及多个子频段之间的间隙。
基站也可以选择包含间隙的BWP作为初始BWP，例如在聚合频段中配置的BWP都是包含间隙的，那么基站可以选择一个包含间隙的BWP作为初始BWP。
图4是根据本公开的实施例示出的又一种频段指示方法的示意流程图。如图4所示，所述方法还包括：
在步骤S401中，向所述终端发送激活指示信息，用于指示激活配置的至少一个BWP中的一个BWP作为激活BWP；
其中，所述激活指示信息包括所述激活BWP对应的物理资源块PRB(Physical Resource Block)的频域资源序号。
在一个实施例中，基站可以通过激活指示信息，在配置给终端的至少一个BWP中选择一个BWP激活，终端根据激活指示信息可以在基站配置的至少一个BWP中选择一个BWP激活，并在激活的BWP上与基站通信。
基站可以确定激活BWP对应的PRB频域资源序号，并通过频域资源序号作为激活指示信息对终端进行指示。终端根据频域资源序号对应的频域资源，可以在配置的BWP中确定基站指示激活的BWP，例如频域资源序号为PRBx至PRBy，其中PRBx对应图3中子频段f2的起点，PRBy对应子频段f2的终点，那么终端可以确定激活的BWP为BWP2。
在一个实施例中，所述终端和所述基站预先存储有PRB频域资源序号与频域资源的关联关系，其中，所述关联关系中对应所述子频段之间间隙的PRB被预先标记为对应间隙。
终端和基站可以预先存储PRB频域资源序号与频域资源的关联关系，进而基站在确定激活BWP后，可以根据关联关系确定激活BWP起点对应的频域资源对应的PRB频域资源序号，以及激活BWP终点对应的频域资源对应的PRB频域资源序号，进而将确定的PRB频域资源序号作为激活指示信息发送给终端。
终端接收到激活指示信息后，可以根据关联关系确定PRB频域资源序号对应的频域资源对应的激活BWP起点和激活BWP终点，进而根据激活BWP起点和激活BWP终点确定激活BWP。
在一个实施例中，所述方法还包括：
接收所述终端发送的能力信息；
根据所述能力信息确定所述终端支持的频段，其中，所述终端支持的频段包括所述聚合频段。
终端可以确定自身支持的频段，所述终端可以支持所述聚合频段，通过向基站发送能力信息指示终端所支持的频段。基站可以根据能力信息确定终端支持的频段，若终端支持聚合频段，可以指示终端在聚合频段与基站通信，若终端不支持聚合频段，那么可以指示终端在其支持的频段与基站通信。
图5是根据本公开的实施例示出的一种频段确定方法的示意流程图。本实施例所示的频段确定方法可以由终端执行，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。所述终端可以作为用户设备与基站通信，所述基站包括但不限于4G基站、5G基站、6G基站等通信系统中的基站。
如图5所示，所述频段确定方法可以包括以下步骤：
在步骤S501中，接收基站发送的频段指示信息；
在步骤S502中，根据所述频段指示信息确定在聚合频段与所述基站通信，其中，所述聚合频段具有新的频段标号，且包括多个子频段，所述多个子频段中至少两个相邻的子频段不连续。
在一个实施例中，在通信频段上可能存在一些零散的频段，这些频段并不连续，并且每个频段的带宽较小，例如在1GHz左右存在一些零散的频段被重耕给5G系统，这些频段的带宽在30M左右。这些频段单独使用难以满足5G通信某些业务场景的需要，例如在进行eMBB业务时，所需带宽要达到100M。
根据本公开的实施例，基站可以确定多个子频段，多个子频段中至少两个相邻的子频段之间不连续，例如多个子频段中有两个相邻的子频段之间不连续，例如多个子频段中的每个子频段之间都不连续，例如部分子频段之间连续且部分子频段之间不连续。进而基站可以将多个子频段作为一个聚合频段指示给终端，从而使得多个子频段作为一个聚合频段的带宽能够满足大多数业务的需要，使得子频段在自身带宽较小，又与其他子频段不连续的情况下，也能够得到有效的利用。在本公开的所有实施例中，两个相邻的子频段不连续是指，两个相邻的子频段之间具有间隙，即两个子频段之间在频率上不连续。
需要说明的是，所述子频段包括但不限于重耕给5G的零散频段。聚合频段中的每个子频段在聚合之前是独立的频段，聚合后得到的聚合频段作为一个新的频段，具有新的频段标号，不使用目前已有频段的标号。即：聚合频段的标识为唯一的标识，与已有的标识不同。
在一个实施例中，所述多个子频段包括时分双工子频段和/或频分双工子频段。
若聚合频段中的多个子频段为时分双工子频段，终端可以按照时分双工的方式在聚合频段与基站通信；若聚合频段中的多个子频段为频分双工子频段，终端可以按照频分双工的方式在聚合频段与基站通信。
图6是根据本公开的实施例示出的另一种频段确定方法的示意流程图。如图6所示，所述方法还包括：
在步骤S601中，接收所述基站发送的至少一个带宽部分BWP的配置信息；
在步骤S602中，根据所述配置信息确定所述BWP工作于所述聚合频段内，以及每个所述BWP对应的带宽。
在一个实施例中，基站可以向终端发送配置信息，来为终端在聚合频段内配置至少一个BWP，以及配置每个BWP对应的带宽。终端根据配置信息可以在聚合频段内确定至少一个BWP，并确定每个BWP对应的带宽。在另一个实施例中，UE可以根据相关通信标准确定BWP即该BWP对应的带宽；基站可以根据相关通信标准确定BWP即该BWP对应的带宽；例如协议中提供预定确定方式(例如计算公式)来确定BWP对应的带宽。在又一个实施例中，UE可以和基站协商确定BWP对应的带宽。即，每个BWP对应的带宽可以是基于基站配置的，也可以是基于协议确定的，还可以由基站与UE协商确定。
在一个实施例中，所述至少一个BWP可以是1个至4个BWP，也即基站可以在在聚合频段内至少配置一个BWP，至多配置4个BWP，这与目前在频段内配置BWP的数量是相同的，可以减少对已有规则的修改。
在一个实施例中，所述BWP对应的带宽包括以下至少之一：
一个完整的子频段、一个子频段中的部分带宽、多个完整的子频段以及多个完整的子频段之间的间隙、多个子频段中的部分带宽以及多个子频段之间的间隙。
在一个实施例中，如图3所示，例如聚合频段包括3个子频段f1、f2和f3，其中f1和f3的带宽为30M，f2的带宽为40M，那么聚合频段的带宽为100M。相邻的两个带宽之间存在间隙gap，例如图3所示的两个间隙的带宽相等，均为10M，间隙为不可用(是指针对某个通信系统不可用)的带宽，例如f1、f2和f3被重耕为5G系统，但是间隙并没有被重耕给5G系统，那么间隙在5G系统中就是不可用的。
以为终端在聚合频段配置4个BWP为例，其中BWP1可以对应子频段f1中的部分带宽，BWP2对应完整的子频段f2，BWP3对应两个子频段f2和f3中的部分带宽以及f2和f3之间的间隙，BWP4对应f1、f2、f3这三个完整的子频段，以及这三个子频段之间的两个间隙。
在一个实施例中，所述方法还包括：
在初始BWP上接收广播信道和/或同步信号块；
其中，所述初始BWP对应一个完整的子频段或一个子频段中的部分带宽。
基站可以在配置给终端的带宽部分中选一个带宽部分作为初始(initial)BWP，进而可以在初始BWP上发送广播信道，也可以在初始BWP上发送同步信号块(其中可以包括同步信号和广播信道)。
由于基站在初始BWP上发送广播信道和/或SSB时，一般还没有向终端发送上述配置信息，那么终端尚未确定聚合频段内的带宽部分BWP，但是终端已经确定了上述聚合频段，所以终端可以在聚合频段中进行搜索，以大致确定初始BWP。
在这种情况下，由于间隙对应带宽是不可用的，所以终端一般不会在间隙上进行搜索，因此基站选择初始BWP时，可以优先选择不包含间隙的BWP作为初始BWP，例如初始BWP对应一个完整的子频段或一个子频段中的部分带宽，以便终端搜索到初始BWP。
在一个实施例中，所述初始BWP还对应多个完整的子频段以及多个完整的子频段之间的间隙、多个子频段中的部分带宽以及多个子频段之间的间隙。
基站也可以选择包含间隙的BWP作为初始BWP，例如在聚合频段中配置的BWP都是包含间隙的，那么基站可以选择一个包含间隙的BWP作为初始BWP。
图7是根据本公开的实施例示出的又一种频段确定方法的示意流程图。如图7所示，所述方法还包括：
在步骤S701中，接收所述基站发送的激活指示信息；

在一个实施例中，基站可以通过激活指示信息，在配置给终端的至少一个BWP中选择一个BWP激活，终端根据激活指示信息可以在基站配置的至少一个BWP中选择一个BWP激活，并在激活的BWP上与基站通信。
基站可以确定激活BWP对应的PRB频域资源序号，并通过频域资源序号作为激活指示信息对终端进行指示。终端根据频域资源序号对应的频域资源，可以在配置的BWP中确定基站指示激活的BWP，例如频域资源序号为PRBx至PRBy，其中PRBx对应图3中子频段f2的起点，PRBy对应子频段f2的终点，那么终端可以确定激活的BWP为BWP2。
在一个实施例中，所述终端和所述基站预先存储有PRB频域资源序号与频域资源的关联关系，其中，所述关联关系中对应所述子频段之间间隙的PRB被预先标记为对应间隙。
终端和基站可以预先存储PRB频域资源序号与频域资源的关联关系，进而基站在确定激活BWP后，可以根据关联关系确定激活BWP起点对应的频域资源对应的PRB频域资源序号，以及激活BWP终点对应的频域资源对应的PRB频域资源序号，进而将确定的PRB频域资源序号作为激活指示信息发送给终端。
终端接收到激活指示信息后，可以根据关联关系确定PRB频域资源序号对应的频域资源对应的激活BWP起点和激活BWP终点，进而根据激活BWP起点和激活BWP终点确定激活BWP。
在一个实施例中，所述方法还包括：
