本申请要求在2018年06月21日提交中国专利局、申请号为201810643004.X、申请名称为“一种通信方法及装置”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
本申请实施例涉及通信技术领域,尤其涉及一种通信方法及装置。
背景技术
第五代(5th Generation,5G)通信***中定义了多种标准带宽,例如5MHz、10MHz、15MHz、20MHz、30MHz,运营商需要按照5G定义的标准带宽进行布网。但是有些运营商的频谱是非连续的,这些非连续的频谱也可以称为离散频谱,运营商拥有的离散频谱中的一段频谱的带宽并不一定正好是上述标准带宽。举例来说,如图1所示,在925.1MHz~955.1MHz的频段上,运营商A拥有离散频谱的带宽分别为5MHz、4.6MHz和7.8MHz,其中,4.6MHz和7.8MHz不能恰好符合标准带宽,4.6MHz的带宽将不能被部署在5G通信***中,7.8MHz的带宽也只能按照标准带宽5MHz来部署,浪费2.8MHz的频谱资源。
基于此,现有技术中提出方案将多个离散频谱组成一个大的***带宽,网络设备和终端按照大的***带宽进行频谱资源的配置和利用,这样可以提升频谱效率。例如,如图1所示,将925.1MHz~955.1MHz的频段所在的30MHz作为大的***带宽,该运营商A应用30MHz的***带宽中的可用频段,网络设备在30MHz的***带宽中的可用频段上为终端分配资源,并且,网络设备向终端通知保留资源以及可以使用的资源的位置,该保留资源是指该终端不能接收下行信号的资源。在下行方向,终端采用***带宽大小的滤波器来接收整个***带宽上的信号,根据获取的保留资源以及可以使用的资源的位置,在接收到的整个***带宽上的信号中获取自身所需要的信息。
但是,在包含离散频谱的***带宽中可能会存在其他运营商的频谱,在其他运营商的频谱上可能会有该其他运营商的网络设备发送信号,在这种情况下,终端接收到的***带宽的信号中可能会包含其他运营商的网络设备发送的信号,从而导致终端的下行信号受到其他运营商的网络设备发送信号的干扰。
发明内容
本申请实施例提供一种通信方法及装置,用以解决当包含离散频谱的***带宽中还存在其他运营商的频谱时,终端如何获知可用频域资源的问题。
本申请实施例提供的具体技术方案如下:
第一方面,提供一种通信方法,该方法通过以下步骤实现:终端从网络设备接收指示信息,为方便描述该指示信息称为第一指示信息,该第一指示信息用于指示带宽中能够用 于所述终端与所述网络设备进行通信的可用频域资源,终端占用的频域资源(即网络设备为终端分配的频域资源)属于可用频域资源,其中,所述带宽为一个载波带宽或一个载波带宽部分,也可以说所述带宽为一个***带宽,所述可用频域资源包括多个不连续的频域资源组,所述频域资源组包括一个或多个连续的频域资源块;所述终端根据所述第一指示信息,确定所述带宽中的所述可用频域资源。这样,终端通过从网络设备接收到的指示信息,确定带宽中的可用频域资源,从而终端可以避开干扰。进一步的,由于终端获知可用频域资源,则具备根据可用频域资源采用合适大小的窄带滤波器对信号进行接收的条件,当终端使用多个不连续的频域资源组构成的带宽时,能够通过合适大小的窄带滤波器过滤掉其他***的信号,有助于避免其他***的信号的干扰,提高数据传输质量。
在一个可能的设计中,所述第一指示信息包括比特序列,所述比特序列中的比特值用于指示所述可用频域资源,例如,比特序列中的一个比特值用于指示一个频域资源组是否属于可用频域资源,可选的,若比特值为1,则指示该比特值对应的频域资源组属于可用频域资源,比特序列中值为1的比特对应的频域资源组为可用频域资源;或者,比特值为0指示该比特值对应的频域资源组属于可用频域资源,比特序列中值为0的比特对应的频域资源组为可用频域资源。通过这种可用频域资源的指示方法,终端能够确定带宽中的可用频域资源,也即确定带宽中的不可用频域资源,这样,终端可以根据带宽中的可用频域资源进行信号的处理,比如,根据带宽中的可用频域资源设置滤波的范围,即设置滤波器的大小。

在一个可能的设计中,所述第一指示单元用于指示所述频域资源组的以下至少两项:起始位置、长度和结束位置。通过这种可用频域资源的指示方法,终端能够确定带宽中的可用频域资源,也即确定带宽中的不可用频域资源,这样,终端可以根据带宽中的可用频域资源进行信号的处理,比如,根据带宽中的可用频域资源设置滤波的范围,即设置滤波器的大小。
可选的,所述第一指示单元的内容为所述频域资源组的频域位置,或者,所述第一指示单元为索引值,索引值与频域资源组的频域位置有着对应关系,通过索引值来指示频域资源组的频域位置,例如,索引值为资源指示版本。其中,频域资源组的频域位置可以是频域资源组的以下至少两项:起始位置、长度和结束位置。通过这种可用频域资源的指示方法,终端能够确定带宽中的可用频域资源,也即确定带宽中的不可用频域资源,这样,终端可以根据带宽中的可用频域资源进行信号的处理,比如,根据带宽中的可用频域资源设置滤波的范围,即设置滤波器的大小。

在一个可能的设计中,所述终端确定所述带宽中除所述第一频域位置到所述第二频域位置之间的频率以外的频域资源不属于可用频域资源;或者,所述终端确定在第一频域位置和/或第二频域位置上的收发功率低于预设值。收发功率包括发送或接收。

本申请实施例提供的通信方法可以应用于***(4thgeneration,4G)通信***、第五代(5th generation,5G)通信***或未来的各种通信***。
下面将结合附图,对本申请实施例进行详细描述。
图2示出了本申请实施例提供的通信方法适用的一种可能的通信***的架构,参阅图2所示,通信***200中包括:网络设备201和一个或多个终端202。当通信***200包括核心网时,网络设备201还可以与核心网相连。网络设备201可以通过核心网与IP网络203进行通信,例如,IP网络203可以是:因特网(internet),私有的IP网,或其它数据网等。网络设备201为覆盖范围内的终端202提供服务。例如,参见图2所示,网络设备201为网络设备201覆盖范围内的一个或多个终端202提供无线接入。通信***200中可以包括多个网络设备,例如还可以包括网络设备201’。网络设备之间的覆盖范围可以存在重叠的区域,例如网络设备201和网络设备201’之间的覆盖范围存在重叠的区域。网络设备之间还可以互相通信,例如,网络设备201可以与网络设备201’之间进行通信。
网络设备201为无线接入网(radio access network,RAN)中的节点,又可以称为基站,还可以称为RAN节点(或设备)。目前,一些网络设备201的举例为:gNB/NR-NB、传输接收点(transmission reception point,TRP)、演进型节点B(evolved Node B,eNB)、无线网络控制器(radio network controller,RNC)、节点B(Node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved NodeB,或home Node B,HNB)、基带单元(base band unit,BBU),或无线保真(wireless fidelity,Wifi)接入点(access point,AP),或5G通信***或者未来可能的通信***中的网络侧设备等。
终端202,又称之为用户设备(user equipment,UE)、移动台(mobile station,MS)、移动终端(mobile terminal,MT)等,是一种向用户提供语音或数据连通性的设备,也可以是物联网设备。例如,终端202包括具有无线连接功能的手持式设备、车载设备等。目前,终端202可以是:手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device,MID)、可穿戴设备(例如智能手表、智能手环、计步器 等),车载设备(例如,汽车、自行车、电动车、飞机、船舶、火车、高铁等)、虚拟现实(virtual reality,VR)设备、增强现实(augmented reality,AR)设备、工业控制(industrial control)中的无线终端、智能家居设备(例如,冰箱、电视、空调、电表等)、智能机器人、车间设备、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端,或智慧家庭(smart home)中的无线终端、飞行设备(例如,智能机器人、热气球、无人机、飞机)等。
为方便理解,首先介绍一下本申请实施例中涉及到的几个概念。
1)本申请实施例中涉及的带宽可以是指一个载波带宽或一个载波带宽部分,或一个***带宽。通常来讲,载波带宽可以理解为网络侧占用的带宽,载波带宽部分可以理解为终端占用的带宽,一个载波带宽可以包括一个或多个载波带宽部分。例如,20MHz的载波带宽可以划分成两个10MHz的载波带宽部分。本申请实施例的方法中涉及的带宽可以是由离散频谱组成的大带宽。离散频谱也可以称为不连续的频域资源组,一个频域资源组占用一部分带宽,一个频域资源组包括一个或多个连续的频域资源块。
2)带宽中的这些不连续的频域资源组为通信***中的可用频域资源,本申请实施例提供的方法中涉及的可用频域资源是指带宽中能够用于终端与网络设备进行通信的资源,或者说终端和网络设备所属的运营商占用的资源。带宽中不能用于终端与网络设备进行通信的资源称为不可用频域资源,不可用频域资源可能由其它运营商占用。带宽中的不可用频域资源与可用频域资源的交集为空,即没有重叠的部分。
以上几个概念通过图1所示来举例说明,例如,如图1所示的30MHz的大带宽,包含多个不连续的频谱资源组:5MHz、4.6MHz和7.8MHz。这几段不连续的频域资源组共同组成可用频域资源,可供终端和网络设备通信时使用,网络设备分配给终端的资源位于该可用频域资源内,可用频域资源还可以供通信***中的其他终端使用。除该不连续的频域资源组之外的资源为不可用频域资源,可能由其它运营商占用。
基于上述描述和图2所示的通信***架构,如图3所示,下面详细介绍一下本申请实施例提供的通信方法。
本申请实施例提供的方法的主要思想是,网络设备向终端指示可用频域资源或者不可用频域资源,终端根据网络设备的指示信息确定带宽中的可用频域资源和/或不可用频域资源,从而可以根据可用频域资源和/或不可用频域资源,执行后续信号的发送或接收过程。其中,可用频域资源和不可用频域资源均是带宽中的一段资源,本申请实施例中带宽中的可用频域资源包括多个不连续的频域资源组,不可用频域资源可以包括一个或多个不连续的频域资源组,因此,网络设备向终端指示可用频域资源和指示不可用资源的方法是类似的,以及,终端确定带宽中的可用频域资源和不可用频域资源的方法也是类似的,两种资源的指示方法或确定方法可以相互参见。终端在已知带宽的情况下,当在确定可用频域资源和不可用频域资源中的一个时,就可以确定另一个。以下描述中,终端确定可用频域资源后的操作也适用于终端在确定不可用频域资源后的操作。
以下描述中,主要介绍可用频域资源的指示方法以及可用资源的确定方法,可以理解的是,可以将可用频域资源的指示方法和确定方法应用于不可用频域资源。
步骤301、网络设备向终端发送第一指示信息,终端从网络设备接收第一指示信息。
该第一指示信息用于指示带宽中的可用频域资源。
步骤302、终端根据第一指示信息,确定带宽中的可用频域资源。
以下对上述通信方法中的可能的实现方式做进一步详细说明。
首先介绍一下第一指示信息的几种可能的表现形式。
表现形式一:
第一指示信息包括一个比特序列,该比特序列也可以理解为比特图样(bitmap),比特序列中的比特值用于指示可用频域资源。一个比特序列为一个字段,该字段中的每个比特对应的指示一个频域资源块,或者,该字段中的每个比特对应的指示多个连续的频域资源块。可选的,比特序列中的元素包括1和0。
在一种可能的实现方式中,比特序列中的一个比特用于指示一个频域资源块,比特序列的长度等于带宽中频域资源块的数量。例如,比特值为1表征该比特对应的频域资源块为可用频域资源,比特值为0表征该比特对应的频域资源块为不可用频域资源。当然,也可以定义为,比特值为0表征该比特对应的频域资源块为可用频域资源,比特值为1表征该比特对应的频域资源块为不可用频域资源。
在另一种可选的实现方式中,比特序列中的一个比特用于指示多个连续的频域资源块,比特序列的长度也可以小于带宽中频域资源块的数量。比特序列中的每个比特也可以对应N个连续的频域资源块,N可以为大于1的正整数,如2,4,6等。例如,比特值为1表征该比特对应的N个连续的频域资源块为可用资源,比特值为0表征该比特对应的N个连续的频域资源块为不可用频域资源。又例如,还可以定义为,比特值为0表征该比特对应的N个连续的频域资源块为可用资源,比特值为1表征该比特对应的N个连续的频域资源块为不可用频域资源。
网络设备通过比特序列中的比特值来指示哪些频域资源块为可用频域资源,哪些频域资源块为不可用资源。终端通过比特序列中的比特值来确定带宽中的可用频域资源和不可用频域资源。
以图1所示带宽来举例说明,如图1中所示的30MHz的带宽,子载波间隔为15kHz,带宽中的频域资源块个数为可以是160个。可选的,该比特序列中可以包含160个比特,每个比特对应的指示该160个频域资源块中的一个频域资源块,例如,比特值为1指示该比特对应的频域资源块为可用频域资源。可选的,该比特序列可以包含(160/N)个比特,每个比特对应的指示该160个频域资源块中的N个连续的频域资源块,N为大于1的正整数。N=2时,该比特序列可以包含80个比特,每个比特对应的指示该160个频域资源块中的2个连续的频域资源块,例如,比特值为1指示该比特对应的2个连续的频域资源块为可用频域资源。N=4时,该比特序列包含40个比特,每个比特对应的指示该160个频域资源块中的4个连续的频域资源块,例如,比特值为1指示该比特对应的4个连续的频域资源块为可用频域资源。
通过图4a所示的例子来进一步说明。例如,如图4a所示,带宽中包括52个频域资源块,该52个频域资源块的编号0~51,即编号为0、1、2、……、51,带宽中包括可用频域资源和不可用频域资源,可用频域资源和不可用频域资源用虚线隔开示意,可用频域资源包括两个不连续的频域资源组,其中的一个频域资源组包括20个连续的频域资源块,另一个频域资源组包括22个连续的频域资源块。可选的,该比特序列可以包含52个比特,每个比特对应的指示该52个频域资源块中的一个频域资源块,例如,比特值为1指示该比特对应的频域资源块为可用频域资源,比特序列为{1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0  0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1}。可选的,该比特序列可以包含(52/N)个比特,每个比特对应的指示该52个频域资源块中的N个连续的频域资源块,N为大于1的正整数。N=2时,该比特序列包含26个比特,每个比特对应的指示该52个频域资源块中的2个连续的频域资源块,例如,比特值为1指示该比特对应的2个连续的频域资源块为可用频域资源,比特序列为{1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1}。
表现形式二:
第一指示信息中包括多个指示单元,这里可称为第一指示单元。一个第一指示单元用于指示一个频域资源组,多个第一指示单元与多个不连续的频域资源组对应。一个指示单元可以理解为是一个字段。具体的,第一指示单元可以用于指示频域资源组的频域位置,例如第一指示单元可以用于指示频域资源组的以下至少两项:起始位置、长度和结束位置。
例如,如图4a所示,带宽中包括52个频域资源块,该52个频域资源块的编号0~51,即编号为0、1、2、……、51,带宽中包括可用频域资源和不可用频域资源,可用频域资源包括两个不连续的频域资源组,其中的一个频域资源组包括20个连续的频域资源块,另一个频域资源组包括22个连续的频域资源块。第一指示信息包括两个第一指示单元,一个第一指示单元用于指示一个对应的频域资源组。
可选的,第一指示单元指示频域资源组的起始位置和长度。其中一个第一指示单元为{0,20},其中,0表示频域资源组的起始位置为编号为0的频域资源块,20表示频域资源组的长度为20个频域资源块,即该第一指示单元{0,20}指示的频域资源组为编号为0的资源块开始的连续的20个频域资源块。另一个第一指示单元为{30,22},其中,30表示频域资源组的起始位置为编号为30的频域资源块,22表示频域资源组的长度为22个频域资源块,即该第一指示单元{30,22}指示的频域资源组为编号为30的频域资源块开始的连续的22个频域资源块。
可选的,第一指示单元用于指示频域资源组的起始位置和结束位置。其中一个第一指示单元为{0,19},该第一指示单元用于指示该频域资源组的起始位置为编号为0的频域资源块,以及该频域资源组的结束位置为编号为19的频域资源块。另一个第一指示单元为{30,51},该第一指示单元用于指示该频域资源组的起始位置为编号为30的频域资源块,以及用于指示该频域资源组的结束位置为编号为51的频域资源块。
可选的,第一指示单元用于指示频域资源组的结束位置和长度。其中一个第一指示单元为{19,20},该第一指示单元用于指示该频域资源组的结束位置为编号为20的频域资源块,以及用于指示该频域资源组的长度为20个频域资源块。另一个第一指示单元为{51,22},该第一指示单元用于指示该频域资源组的结束位置为编号为51的频域资源块,以及用于指示该频域资源组的长度为22个频域资源块。
可选的,第一指示单元还可以指示一个索引值,该索引值与频域资源组的频域位置具有对应关系,通过索引值来指示频域资源组的频域位置。该对应关系为预先确定的,网络设备和终端设备对于该对应关系有相同的理解。例如,该索引值可以是资源指示版本(resource indication version,RIV)。RIV应理解为一种索引值与频域资源组的起始位置和长度的对应关系。
以下介绍一下第一指示信息的其它指示作用。
如上述方法中所述,第一指示信息用于指示带宽中的可用频域资源,可选的,第一指示信息还可以用于指示频域资源组的参考频域位置,若带宽中有多个频域资源组,则多个 第一指示信息对应的指示多个参考频域位置,一个第一指示信息用于指示一个频域资源组的参考频域位置。其中,参考频域位置包括第一频域位置和第二频域位置中的至少一个,第一频域位置低于频域资源组的起始位置,第二频域位置高于频域资源组的结束位置。需要说明的是,第一频域位置低于频域资源组的起始位置可以理解为第一频域位置对应的频率小于频域资源组中第一个频域资源块的第一个子载波对应的频率,第二频域位置高于频域资源组的结束位置可以理解为第二频域位置对应的频率大于频率资源组中最后一个频域资源块的最后一个子载波对应的频率。第一频域位置与该起始位置之间的带宽可以认为是该频域资源组的保护带宽,该结束位置与第二频域位置之间的带宽可以认为是该频域资源组的保护带宽。如图4b所示,示出了一个频域资源组的参考频域位置的示例,图4b中的阴影部分的带宽为该保护带宽,参考频域位置包括位于该频域资源组的低频侧位置的第一频域位置,以及位于该频域资源组的高频侧位置的第二频域位置。
在一个可能的实现方式中,第一指示信息直接指示参考频域位置。例如,第一指示信息通过绝对无线频道号(absolute radio frequency channel number,ARFCN)来指示参考频域位置,一个ARFCN对应一个绝对的频率。又例如,第一指示信息指示参考频率位置对应的子载波的编号,该子载波的编号可以是以带宽的公共参考点作为基准的编号,该公共参考点可以是NR***中的参考点A(Point A)。应理解,参考点A的实质为公共参考点,并不对其名称进行限定。具体的,公共参考点的子载波编号为0,则第一指示信息可以指示参考频率位置对应的子载波为X,X为正整数,从而终端设备可以先确定公共参考点所在的频率F1,再确定参考频率位置的频率F2=F1+X×S,其中,S为子载波间隔,取值可以是15kHz或其他值。
在另一个可能的实现方式中,第一指示信息指示第一频域位置与频域资源组的起始位置之间的第一偏移值,或者指示第二频域位置与频域资源组的结束位置之间的第二偏移值,或者同时指示第一偏移值和第二偏移值,第一偏移值和第二偏移值可以相同,也可以不同。可选的,第一偏移值可以以子载波间隔为单位,从而第一指示信息指示第一频域位置与频域资源组的起始位置偏差A个子载波间隔,此处的频域资源组的起始位置应理解成该频域资源组的第一个频域资源块的第一个子载波的频率,其中,第一偏移值对应的子载波间隔可以与频域资源块的子载波间隔相同,也可以不同,此处不做限定。可选的,第一偏移值可以以5kHz为单位,从而第一指示信息指示第一频域位置与频域资源组的起始位置偏差B×5kHz的频率。同理,第二偏移值也可以以子载波间隔为单位,第一指示信息指示第二频域位置与频域资源组的结束位置偏差C个子载波间隔,此处的频域资源组的结束位置应理解成该频域资源组的最后一个频域资源块的最后一个子载波的频率,其中,第二偏移值对应的子载波间隔可以与频域资源块的子载波间隔相同,也可以不同,此处不作限定。例如,第二偏移值可以为5kHz,第一指示信息指示第二频域位置与频域资源组的结束位置偏差D×5kHz的频率。A、B、C、D均为正整数。可选的,第一指示信息还可以只指示一个偏移值,该偏移值的指示方法参考上述方法,此处不再赘述。此时,终端设备可以确定第一频域位置与频域资源组的起始位置之间的第一偏移值等于第一指示信息指示的偏移值,同时确定第二频域位置与频域资源组的结束位置之间的第二偏移值也等于第一指示信息指示的偏移值。如图4b所示,第一偏移值可以认为是位于该频域资源组的低频位置的阴影部分带宽,第二偏移值可以认为是位于该频域资源组的高频位置的阴影部分带宽。
在带宽中有多个频域资源组的情况下,每一个频域资源组的参考频域位置都通过第一 指示信息来指示。例如,第一指示信息中包括多个指示单元,每个指示单元对应一个频域资源组,并指示对应频域资源组的参考频域位置。进一步的,如上所述,第一指示信息的表现形式包括两种可能的实现方式。在一种可能的实现方式中,第一指示信息中包括比特序列,在这种情况下,第一指示信息还包括多个指示单元,为方便说明,这里的指示单元称为第二指示单元,每个第二指示单元对应指示一个频域资源组的参考频域位置。相对应的,第二指示单元直接指示参考频域位置。例如,第二指示单元通过ARFCN或子载波编号来指示参考频域位置;或者,第二指示单元指示第一偏移值和第二偏移值中的一项或两项。
在另一种可能的实现方式中,第一指示信息中包括多个第一指示单元,在这种情况下,第一指示单元还用于指示频域资源组的参考频域位置。相对应的,第一指示单元直接指示参考频域位置,例如,第一指示单元通过ARFCN或子载波编号来指示参考频域位置;或者,第一指示单元指示第一偏移值和第二偏移值中的至少一个,具体的,第一指示单元的一部分字段用于指示频域资源组的频域位置,另一部分字段用于指示该频域资源组的第一偏移值和第二偏移值中的至少一个。
通过第一指示信息指示频域资源组的参考频域位置,终端能够根据参考频域位置更加精确的确定可以滤波的窄带范围,能够更加灵活配置滤波器的大小,例如,终端可以参考频域资源组的大小结合参考频域位置来设置滤波器的大小,对滤波器的要求有一定的降低。
以下介绍一下终端在被调度后的一些可能的实现方式中的操作。
终端在确定带宽中的可用频域资源后,在被调度时,终端会基于可用频域资源进行信号的发送和接收。类似的,终端在确定带宽中的不可用频域资源后,在被调度时,终端不会在不可用频域资源进行信号的发送和接收。
针对下行信号传输,具体的,网络设备向终端发送第二指示信息,第二指示信息用于指示下行资源,该下行资源用于终端从网络设备接收下行信号,该下行资源位于带宽内,终端从网络设备接收第二指示信息,获取网络设备指示的下行资源。可选的,该第二指示信息通常有两种指示方式,第一种指示方式为离散的频域资源指示方式,即第二指示信息包括一个比特序列,该比特序列中的每个比特对应的指示带宽中X个连续的频域资源块。现有技术中,指示下行资源时需要对带宽中的所有频域资源块进行指示,当带宽中总的频域资源块个数为Y个时,用于指示下行资源的信息(如下行指示信息)包括的比特序列有Y/X个比特,若Y/X为非整数时,可以进行上取整或下取整,通常为上取整。本申请实施例中,第二指示信息包括的比特序列的长度由带宽中下行可用资源块的个数和一个比特所指示的连续资源块个数X确定。本申请实施例中,比特序列的长度即比特序列中包含的比特个数。终端在接收第一指示信息后可以确定Y个频域资源块中的下行可用资源块的个数,下行可用资源块的个数记为Y 1,Y 1<Y,第二指示信息包括的比特序列的长度为Y1/X,若Y 1/X为非整数时,可以进行上取整或下取整,通常为上取整。通过上述提供的第二指示信息指示下行资源的方式,第二指示信息只需要指示下行可用资源块即可,无需对带宽中的所有频域资源块进行指示,与现有技术相比能够有助于降低第二指示信息的比特数,降低网络设备的下行指示资源的开销以及降低终端处理下行指示信息的复杂度。以图4a进行举例,带宽中总的频域资源块个数为Y=52,比特序列每个比特对应带宽中X=2个连续的频域资源块,终端根据第一指示信息确定的可用资源块的个数Y 1=42,第二指示信息包括的比特序列的长度为Y 1/X=21。
第二种指示方式为连续的频域资源指示方式,即第二指示信息包括一个RIV,以指示带宽内一段连续的资源块。现有技术中,用于指示下行资源的信息(如下行指示信息)所需的比特数与带宽中总的频域资源块个数Y相关,通常比特数为log2(Y×(Y+1)/2)进行上取整所得的值。终端在接收第一指示信息后可以确定Y个频域资源块中的下行可用频域资源块的个数,记为Y 1,且Y 1<Y。第二指示信息包括的RIV所需的比特数根据带宽中下行可用频域资源块的个数确定,即log 2(Y 1×(Y 1+1)/2)进行上取整所得的值。通过上述提供的第二指示信息指示下行资源的方式,第二指示信息包括的RIV只需要指示下行可用更便宜资源块即可,无需指示带宽中的总的频域资源块的个数Y,与现有技术相比,第二指示信息包括的比特序列的比特数相应减少,有助于降低网络设备的下行指示资源的开销以及降低终端处理下行指示信息的复杂度。需要说明的是,此时第二指示信息中的RIV指示的频域资源块为按照可用频域资源块进行索引的。例如,以图4a为例,当RIV指示一段连续的频域资源块的起始资源块为编号19的资源块,长度为2,则终端确定的频域资源块为图4a中的编号为19和编号为30的两个频域资源块。
基于以上两种第二指示信息的指示方式,第二指示信息只用于指示带宽中的下行可用资源块。若第二指示信息仍采用现有技术的指示方式,则第二指示信息所指示的下行资源为一段连续的资源块,该连续的资源块可能位于一个频域资源组内,这种情况下,下行资源与不可用频域资源的交集为空。该连续的资源块也可能位于多个频域资源组内,由于多个频域资源组是不连续的,第二指示信息所指示的下行资源也可能包含下行不可用频域资源块,这种情况下,下行资源与不可用频域资源之间交集不为空。
当第二指示信息所指示的下行资源中包含下行不可用频域资源块时,终端仅在下行可用频域资源块上接收下行信号。
需要说明的是,本申请实施例的描述中,下行可用频域资源块是指既属于下行资源又属于可用频域资源的资源块,也可以说下行可用频域资源块属于一个或多个频域资源组,下行不可用频域资源块是指下行资源中不属于可用频域资源的资源块,也可以说下行不可用频域资源块不属于任一频域资源组。
若下行可用频域资源块位于多个频域资源组内,则终端采用多个射频单元在多个频域资源组上接收下行信号,多个射频单元与多个频域资源组对应,一个射频单元对应一个频域资源组。
若下行可用频域资源块位于多个频域资源组内,则终端采用多个滤波器对多个频域资源组上接收的下行信号进行处理,多个滤波器与多个频域资源组对应,一个滤波器对应着一个频域资源组。具体的,终端根据频域资源组的大小来设置滤波器的大小,可选的,终端还可以根据频域资源组的大小和参考频域位置来设置滤波器的大小,这样,终端可以根据多个频域资源组确定多个滤波器,采用多个滤波器对多个频域资源上接收的下行信号进行滤波处理,能够有效避免下行不可用频域资源上其它***信号的干扰,当结合参考频域位置来设置滤波器的大小时,能够更加灵活的设置滤波器的大小,降低对滤波器的要求。
针对上行信号传输,具体的,网络设备向终端发送第三指示信息,第三指示信息用于指示上行资源,该上行资源用于终端向网络设备发送上行信号,该上行资源位于带宽内,终端从网络设备接收第三指示信息。与第二指示信息的指示方式类似,第三指示信息通常有两种指示方式,第一种指示方式为离散的频域资源指示方式,即第三指示信息包括一个比特序列,该比特序列中的每个比特对应的指示带宽中X个连续的频域资源块。现有技术 中,指示上行资源时需要对带宽中的所有频域资源块进行指示,当带宽中总的频域资源块个数为Y个时,用于指示上行资源的信息(如上行指示信息)包括的比特序列有Y/X个比特,若Y/X为非整数时,可以进行上取整或下取整,通常为上取整。本申请实施例中,第三指示信息包括的比特序列的长度由带宽中上行可用资源块的个数和一个比特所指示的连续资源块个数X确定。本申请实施例中,比特序列的长度即比特序列中包含的比特个数。终端在接收第一指示信息后可以确定Y个频域资源块中的上行可用资源块的个数,上行可用资源块的个数记为Y 1,Y 1<Y,第二指示信息包括的比特序列的长度为Y 1/X,若Y 1/X为非整数时,可以进行上取整或下取整,通常为上取整。通过上述提供的第三指示信息指示上行资源的方式,第三指示信息只需要指示上行可用资源块即可,无需对带宽中的所有频域资源块进行指示,与现有技术相比能够有助于降低第三指示信息的比特数,降低网络设备的上行指示资源的开销以及降低终端处理上行指示信息的复杂度。以图4a进行举例,带宽中总的频域资源块个数为Y=52,比特序列每个比特对应带宽中X=2个连续的频域资源块,终端根据第一指示信息确定的可用资源块的个数Y 1=42,第三指示信息包括的比特序列的长度为Y 1/X=21。
第二种指示方式为连续的频域资源指示方式,即第三指示信息包括一个RIV,以指示带宽内一段连续的资源块。现有技术中,用于指示上行资源的信息(如上行指示信息)所需的比特数与带宽中总的频域资源块个数Y相关,通常比特数为log2(Y×(Y+1)/2)进行上取整所得的值。终端在接收第一指示信息后可以确定Y个频域资源块中的上行可用频域资源块的个数,记为Y 1,且Y 1<Y。第三指示信息包括的RIV所需的比特数根据带宽中上行可用频域资源块的个数确定,即log 2(Y 1×(Y 1+1)/2)进行上取整所得的值。通过上述提供的第三指示信息指示上行资源的方式,第三指示信息包括的RIV只需要指示上行可用频域资源块即可,无需指示带宽中的总的频域资源块的个数Y,与现有技术相比,第三指示信息包括的比特序列的比特数相应减少,有助于降低网络设备的上行指示资源的开销以及降低终端处理上行指示信息的复杂度。需要说明的是,此时第三指示信息中的RIV指示的频域资源块为按照可用频域资源块进行索引的。例如,以图4a为例,当RIV指示一段连续的频域资源块的起始资源块为编号19的资源块,长度为2,则终端确定的频域资源块为图4a中的编号为19和编号为30的两个频域资源块。
基于以上两种第二指示信息的指示方式,第三指示信息只用于指示带宽中的上行可用资源块。若第三指示信息仍采用现有技术的指示方式,则第三指示信息所指示的上行资源为一段连续的资源块,该连续的资源块可能位于一个频域资源组内,这种情况下,上行资源与不可用频域资源之间的交集为空。该连续的资源块也可能位于多个频域资源组内,由于多个频域资源组是不连续的,第三指示信息所指示的上行资源也可能包含上行不可用频域资源块,这种情况下,上行资源与不可用频域资源的交集不为空。
当第三指示信息所指示的上行资源中包含上行不可用频域资源块时,终端仅在上行可用频域资源块上发送上行信号。
进一步的,终端向网络设备发送上行信号可以采用正交频分复用(orthogonal frequency division multiplexing,OFDM)波形和离散傅里叶变换扩频的正交频分复用(discrete fourier transform-spread OFDM,DFT-S-OFDM)波形。网络设备会预先给终端配置发送上行信号的波形。针对网络设备预先给终端设备配置发送上行信号的波形为DFT-S-OFDM,若第二指示信息指示的上行资源仅属于一个频域资源组时,终端仍采用DFT-S-OFDM波形发送上 行信号;若第二指示信息指示的上行资源属于至少两个频域资源组时,终端采用OFDM波形发送上行信号。
需要说明的是,本申请实施例的描述中,上行可用频域资源块是指既属于上行资源又属于可用频域资源的资源块。上行不可用频域资源是指上行资源中不属于可用频域资源的资源块。
若上行可用频域资源块位于多个频域资源组内,则终端采用多个射频单元在多个频域资源组上发送上行信号,多个射频单元与多个频域资源组对应,一个射频单元对应一个频域资源组。
若上行可用频域资源块位于多个频域资源组内,则终端采用多个滤波器对多个频域资源组发送的上行信号进行处理,多个滤波器与多个频域资源组对应,一个滤波器对应着一个频域资源组。具体的,终端根据频域资源组的大小来设置滤波器的大小,可选的,终端还可以根据频域资源组的大小和参考频域位置来设置滤波器的大小,这样,终端可以根据多个频域资源组确定多个滤波器,采用多个滤波器对多个频域资源上发送的上行信号进行滤波处理,能够有效避免上行不可用频域资源上其它***信号的干扰,当结合参考频域位置来设置滤波器的大小时,能够更加灵活的设置滤波器的大小,降低对滤波器的要求。
上述描述中,终端在可用频域资源上发送的上行信号可以是上行数据信号、上行控制信号或上行参考信号。上行参考信号包括解调导频、探测导频、相位跟踪导频。终端在可用频域资源上接收的下行信号可以是下行数据信号、下行控制信号或下行参考信号。下行参考信号也可以是下行导频信号,下行导频信号包括解调导频、测量导频、相位跟踪导频、跟踪导频。
若下行可用频域资源块位于多个频域资源组内,下行信号为下行数据信号,下行数据信号包括一个或多个传输块,可以称为第一传输块,则任一第一传输块均承载在位于该多个频域资源组内的所有下行可用频域资源块上。也就是说,网络设备发送的下行数据的整个传输块承载在给终端分配的所有下行可用频域资源块上。
类似的,若上行可用频域资源块属于多个频域资源组,上行信号为上行数据信号,上行数据信号包括至少一个第二传输块,则任一第二传输块均承载在位于该多个频域资源组内的所有上行可用频域资源块上。也就是说,终端发送的上行数据的整个传输块承载在终端占用的所有下行可用频域资源块上。
举例来说,图4a所示的带宽上,若下行可用频域资源块为编号18~编号19以及编号30~编号31的资源块,则下行数据信号包括的每一个第一传输块均承载在编号18~编号19以及编号30~编号31这4个资源块上。类似的,若上行可用频域资源块为编号18~编号19以及编号30~编号31的资源块,则上行数据信号包括的每一个第二传输块均承载在编号18~编号19以及编号30~编号31这4个资源块上。
结合上述对可用资源的指示方法和确定方法,以下介绍一下不可用资源的指示方法和确定方法。如图5所示,本申请实施例中提供的另一种通信方法如下所述。
需要说明的是,上述描述中,第一指示信息若用于指示不可用频域资源,其方法是相同的,在此不再赘述。
步骤501、网络设备向终端发送第一指示信息,终端从网络设备接收第一指示信息。
该第一指示信息用于指示带宽中的不可用频域资源。
步骤502、终端根据第一指示信息,确定带宽中的不可用频域资源。
以下对上述通信方法中的可能的实现方式做进一步详细说明。
首先介绍一下第一指示信息的几种可能的表现形式。
表现形式一:
第一指示信息包括一个比特序列,该比特序列也可以理解为比特图样(bitmap),比特序列中的比特值用于指示带宽中的不可用频域资源。一个比特序列为一个字段,该字段中的每个比特对应的指示一个频域资源块,或者,该字段中的每个比特对应的指示多个连续的频域资源块。可选的,比特序列中的元素包括1和0。
在一种可能的实现方式中,比特序列中的一个比特用于指示一个频域资源块,比特序列的长度等于带宽中频域资源块的数量。例如,比特值为1表征该比特对应的频域资源块为可用频域资源,比特值为0表征该比特对应的频域资源块为不可用频域资源。当然,也可以定义为,比特值为0表征该比特对应的频域资源块为可用频域资源,比特值为1表征该比特对应的频域资源块为不可用频域资源。
在另一种可选的实现方式中,比特序列中的一个比特用于指示多个连续的频域资源块,比特序列的长度也可以小于带宽中频域资源块的数量。比特序列中的每个比特也可以对应N个连续的频域资源块,N可以为大于1的正整数,如2,4,6等。例如,比特值为1表征该比特对应的N个连续的频域资源块为不可用资源,比特值为0表征该比特对应的N个连续的频域资源块为可用频域资源。又例如,还可以定义为,比特值为0表征该比特对应的N个连续的频域资源块为不可用资源,比特值为1表征该比特对应的N个连续的频域资源块为可用频域资源。
网络设备通过比特序列中的比特值来指示哪些频域资源块为可用频域资源,哪些频域资源块为不可用资源。终端通过比特序列中的比特值来确定带宽中的可用频域资源和不可用频域资源。
例如,如图6a所示,带宽中包括79个频域资源块,该78个频域资源块的编号0~78,即编号为0、1、2、……、78,带宽中包括可用频域资源和不可用频域资源,可用频域资源和不可用频域资源用虚线隔开示意,不可用频域资源包括两个不连续的频域资源组,其中一个频域资源组包括10个连续的频域资源块,编号为20~29,另一个频域资源组包括10个连续的频域资源块,编号为52~61。可选的,该比特序列可以包含79个比特,每个比特对应的指示该79个频域资源块中的一个频域资源块,例如,比特值为0指示该比特对应的频域资源块为不可用频域资源,比特序列为{1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1}。可选的,该比特序列可以包含(79/N)个比特,通常情况下取值为向上取整。每个比特对应的指示该79个频域资源块中的N个连续的频域资源块,N为大于1的正整数。N=2时,该比特序列包含40个比特,每个比特对应的指示该79个频域资源块中的2个连续的频域资源块,最后一个比特对应的指示最后一个频域资源块。例如,比特值为0指示该比特对应的频域资源块为不可用频域资源,比特序列为{1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 1 1 1 1 1 1 1 1 1}。
表现形式二:
本部分描述中的频域资源组为不可用频域资源中的频域资源组。
第一指示信息中包括多个指示单元,这里可称为第一指示单元。一个第一指示单元用于指示一个不可用频域资源中的频域资源组,多个第一指示单元与多个不连续的频域资源 组对应。一个指示单元可以理解为是一个字段。具体的,第一指示单元可以用于指示频域资源组的频域位置,例如第一指示单元可以用于指示频域资源组的以下至少两项:起始位置、长度和结束位置。
例如,如图6a所示,带宽中包括79个频域资源块,该79个频域资源块的编号0~78,即编号为0、1、2、……、78,带宽中包括可用频域资源和不可用频域资源,可用频域资源和不可用频域资源用虚线隔开示意,不可用频域资源包括两个不连续的频域资源组,其中一个频域资源组包括10个连续的频域资源块,编号为20~29,另一个频域资源组包括10个连续的频域资源块,编号为52~61。第一指示信息包括两个第一指示单元,一个第一指示单元用于指示一个对应的不可用频域资源的频域资源组。
可选的,第一指示单元指示频域资源组的起始位置和长度。其中一个第一指示单元为{20,10},其中,20表示频域资源组的起始位置为编号为20的频域资源块,10表示频域资源组的长度为10个频域资源块,即该第一指示单元{20,10}指示的频域资源组为编号为20的资源块开始的连续的10个频域资源块。另一个第一指示单元为{52,10},其中,52表示频域资源组的起始位置为编号为52的频域资源块,10表示频域资源组的长度为10个频域资源块,即该第一指示单元{52,10}指示的频域资源组为编号为52的频域资源块开始的连续的10个频域资源块。
可选的,第一指示单元用于指示频域资源组的起始位置和结束位置。其中一个第一指示单元为{20,29},该第一指示单元用于指示该频域资源组的起始位置为编号为20的频域资源块,以及该频域资源组的结束位置为编号为29的频域资源块。另一个第一指示单元为{52,61},该第一指示单元用于指示该频域资源组的起始位置为编号为52的频域资源块,以及用于指示该频域资源组的结束位置为编号为61的频域资源块。
可选的,第一指示单元用于指示频域资源组的结束位置和长度。其中一个第一指示单元为{29,10},该第一指示单元用于指示该频域资源组的结束位置为编号为29的频域资源块,以及用于指示该频域资源组的长度为10个频域资源块。另一个第一指示单元为{61,10},该第一指示单元用于指示该频域资源组的结束位置为编号为61的频域资源块,以及用于指示该频域资源组的长度为10个频域资源块。
可选的,第一指示单元还可以指示一个索引值,该索引值与频域资源组的频域位置具有对应关系,通过索引值来指示频域资源组的频域位置。该对应关系为预先确定的,网络设备和终端设备对于该对应关系有相同的理解。例如,该索引值可以是RIV。RIV应理解为一种索引值与频域资源组的起始位置和长度的对应关系。
以下介绍一下第一指示信息的其它指示作用。
本部分描述中,所述的频域资源组是指不可用频域资源中的频域资源组。
如上述方法中所述,第一指示信息用于指示带宽中的不可用频域资源,可选的,第一指示信息还可以用于指示频域资源组的参考频域位置,若带宽中有多个频域资源组,则多个第一指示信息对应的指示多个参考频域位置,一个第一指示信息用于指示一个频域资源组的参考频域位置。其中,参考频域位置包括第一频域位置和第二频域位置中的至少一个,第一频域位置高于频域资源组的起始位置,第二频域位置低于频域资源组的结束位置,第二频域位置高于第一频域位置。需要说明的是,第一频域位置高于频域资源组的起始位置可以理解为第一频域位置对应的频率大于频域资源组中第一个频域资源块的第一个子载波对应的频率,第二频域位置低于频域资源组的结束位置可以理解为第二频域位置对应的 频率小于频率资源组中最后一个频域资源块的最后一个子载波对应的频率。如图6b所示,示出了一个频域资源组的参考频域位置的示例,参考频域位置包括位于该频域资源组的低频侧位置的第一频域位置,以及位于该频域资源组的高频侧位置的第二频域位置。
在一个可能的实现方式中,第一指示信息直接指示参考频域位置。例如,第一指示信息通过ARFCN来指示参考频域位置,一个ARFCN对应一个绝对的频率。又例如,第一指示信息指示参考频率位置对应的子载波的编号,该子载波的编号可以是以带宽的公共参考点作为基准的编号,该公共参考点可以是NR***中的参考点A(Point A)。应理解,参考点A的实质为公共参考点,并不对其名称进行限定。具体的,公共参考点的子载波编号为0,则第一指示信息可以指示参考频率位置对应的子载波为X,X为正整数,从而终端设备可以先确定公共参考点所在的频率F1,再确定参考频率位置的频率F2=F1+X×S,其中,S为子载波间隔,取值可以是15kHz或其他值。
在另一个可能的实现方式中,第一指示信息指示第一频域位置与频域资源组的起始位置之间的第一偏移值,或者指示第二频域位置与频域资源组的结束位置之间的第二偏移值,或者同时指示第一偏移值和第二偏移值,第一偏移值和第二偏移值的取值可以相等,也可以不相等。可选的,第一偏移值可以以子载波间隔为单位,从而第一指示信息指示第一频域位置与频域资源组的起始位置偏差A个子载波间隔,此处的频域资源组的起始位置应理解成该频域资源组的第一个频域资源块的第一个子载波的频率,其中,第一偏移值对应的子载波间隔可以与频域资源块的子载波间隔相同,也可以不同,此处不做限定。对第一偏移值和第二偏移值的其它理解可参照可用频域资源的指示方法中的相关描述,不再赘述。如图6b所示,第一偏移值可以认为是位于该频域资源组的低频位置的阴影部分带宽,第二偏移值可以认为是位于该频域资源组的高频位置的阴影部分带宽。
在带宽中有多个频域资源组的情况下,每一个频域资源组的参考频域位置都通过第一指示信息来指示。例如,第一指示信息中包括多个指示单元,每个指示单元对应一个频域资源组,并指示对应频域资源组的参考频域位置。进一步的,如上所述,第一指示信息的表现形式包括两种可能的实现方式。在一种可能的实现方式中,第一指示信息中包括比特序列,在这种情况下,第一指示信息还包括多个指示单元,为方便说明,这里的指示单元称为第二指示单元,每个第二指示单元对应指示一个频域资源组的参考频域位置。相对应的,第二指示单元直接指示参考频域位置。例如,第二指示单元通过ARFCN来指示参考频域位置;或者,第二指示单元指示第一偏移值和第二偏移值中的一项或两项。
在另一种可能的实现方式中,第一指示信息中包括多个第一指示单元,在这种情况下,第一指示单元还用于指示频域资源组的参考频域位置。相对应的,第一指示单元直接指示参考频域位置,例如,第一指示单元通过ARFCN来指示参考频域位置;或者,第一指示单元指示第一偏移值和第二偏移值中的至少一个,具体的,第一指示单元的一部分字段用于指示频域资源组的频域位置,另一部分字段用于指示该频域资源组的第一偏移值和第二偏移值中的至少一个。
通过第一指示信息指示不可用频域资源中频域资源组的参考频域位置,终端能够根据参考频域位置更加精确的确定可用频域资源的频域位置,并且能够根据参考频域位置来设置滤波的窄带范围,能够更加灵活配置滤波器的大小,对滤波器的要求有一定的降低。
终端在确定带宽中的不可用频域资源后,在被调度时,终端不会在不可用频域资源进行信号的发送和接收。终端在被调度后的一些可能的实现方式中的操作可以参见可用频域 资源部分的相关描述,在此不再赘述。
可选的,终端还可以根据以下方法来确定不可用频域资源。
首先介绍一下现有技术中,网络设备通过指示信息来指示终端带宽中的保留资源,保留资源是指终端不能接收下行信号的时频资源。需要注意的是,保留资源中的频域资源有可能位于可用频域资源,也有可能位于不可用频域资源,其定义与可用频域资源有区别。
通常,指示信息中包含两个字段,记为第一字段和第二字段,第一字段用于指示终端不能接收下行信号的频域资源,第二字段用于指示终端不能接收下行信号的时域资源。第一字段指示终端不能接收下行信号的频域资源的方式可以参照上述实施例描述的比特序列指示不可用资源的方式。
基于上述保留资源的指示方式,在本部分描述的实现方式中,若第一指示信息中只包含第一字段,不包含第二字段,即第一指示信息中只包含用于指示频域资源的字段,不包含用于指示时域资源的资源,则第一字段用于指示带宽的不可用频域资源。
具体实现中,终端会判断第一指示信息中是否包含第二字段,若不包含,则获取第一指示信息中的第一字段,终端根据该第一字段,确定带宽中的不可用频域资源。
可选的,第一字段指示的不可用频域资源适用于上行通信、或下行通信,或者同时适用于上下行通信。
另外,若终端确定第一指示信息中包含第一字段和第二字段,则根据第一字段确定终端不能接收下行信号的频域资源,根据第二字段确定终端不能接收下行信号的时域资源。需要注意的是,这里通过第一字段和第二字段指示的保留资源只适用于下行通信。
图3所示的方法中的描述可以适用于图5所示的方法中,如第一指示信息的其它指示作用的描述部分,又如终端在被调度后的一些可能的实现方式中的操作等部分都适用于图5所示的方法中。
基于同一发明构思,如图7所示,本申请实施例还提供了另一种通信方法,指示信息用来指示带宽中的可用频域资源和不可用频域资源。具体如下所述。
步骤701、网络设备向终端发送第一指示信息,终端从网络设备接收第一指示信息。
该第一指示信息用于指示带宽中的带宽部分(bandwidth part,BWP)的组号。
步骤702、终端根据第一指示信息,确定所述带宽部分的组号。
在现有技术中,一个带宽部分包括一个或多个频域资源块,网络设备可以通过高层信令,如无线资源控制层信令向终端发送BWP的配置信息,终端能够根据该配置信息获取BWP的频域资源块的起始位置、BWP的频域资源块的结束位置和BWP频域资源块的个数。在本申请实施例中,该第一指示信息可以包括一个字段,该字段中的值用于指示多个分组的带宽部分的组号,或者,该第一指示信息包括多个字段,一个字段用于指示一个组的带宽部分的组号。
进一步的,终端根据带宽部分的组号确定可用频域资源和/或不可用频域资源。具体的,组号相同的带宽部分之间的频域资源为可用频域资源,组号不同的带宽部分之间的频域资源为不可用频域资源。
示例性的,基于图4a,网络设备可以预先为终端配置两个带宽部分,包括BWP0和BWP1,其中,BWP0包括从编号为0的频域资源块到编号为19的频域资源块,共20个频域资源块,BWP1包括从编号为30的频域资源块到编号为51的频域资源块,共22个频域资源块,在该示例中,第一指示信息可以指示BWP0的组号与BWP1的组号不同,如 BWP0的组号为0,BWP1的组号为1,从而终端确定BWP0到BWP1之间的频域资源块为不可用频域资源,该不可用频域资源包括从编号为20的频域资源块到编号为29的频域资源块,共10个频域资源块。
又例如,网络设备预先为终端配置两个带宽部分,包括BWP0和BWP1,其中,BWP0包括编号0到编号5共6个频域资源块,BWP1包括编号14到编号19共6个频域资源块,在该示例中,第一指示信息可以指示BWP0和BWP1的组号相同,如BWP0和BWP1的组号都为0,从而终端确定BWP0到BWP1之间的频域资源块为可用频域资源,即从编号为6到编号为13共8个频域资源块为可用频域资源。
又例如,网络设备预先为终端配置三个带宽部分,包括BWP0、BWP1和BWP2,其中,BWP0包括编号0到编号5共6个频域资源块,BWP1包括编号14到编号19共6个频域资源块,BWP2包括从编号为30的频域资源块到编号为51的频域资源块,共22个频域资源块,在该示例中,第一指示信息可以指示BWP0和BWP1的组号相同,但BWP0和BWP1两者的组号和BWP2的组号不同,如BWP0和BWP1的组号都为0,BWP2的组号为1,从而终端是确定BWP0到BWP1之间的频域资源块,即从编号为6到编号为13共8个频域资源块为可用频域资源,而BWP1到BWP2之间的频域资源块,即从编号为20的频域资源块到编号为29的频域资源块,共10个频域资源块为不可用频域资源。
应理解,同一个组内的带宽部分之间的频域资源块为可用频域资源,不同组的两个带宽部分之间包括不可用频域资源。还可以理解,同一个组内的带宽部分是属于同一个频域资源组的,不同组内的带宽部分不重叠,是属于不同的频域资源组的。
例如,带宽中包括4个带宽部分,编号为BWP0、BWP1、BWP2、BWP3,BWP和BWP1为同一个组内的带宽部分,属于同一个频域资源组,BWP2和BWP3为同一个组内的带宽部分,属于同一个频域资源组,BWP、BWP1与BWP2、BWP3的分组不同。则第一指示信息可以为{0,0,1,1},或者,第一指示信息有两个字段:{0,0}和{1,1}。其中,BWP0的组号为0,BWP1的组号为0,BWP2的组号为1,BWP3的组号为1,组号相同的BWP为同一组的BWP。这样,终端可以根据带宽部分的组号,来确定可用频域资源和不可用频域资源,相同组内的带宽部分可以采用一个窄带滤波器来处理,从而能够避免上下行的干扰。
在另一种可能的实现方式中,该第一指示信息包括多个字段,多个字段用于指示多个组的带宽部分,一个字段用于指示一个组的带宽部分。同一个组内的带宽部分是连续的,同一个组内的带宽部分是属于同一个频域资源组的,不同组内的带宽部分不重叠,是属于不同的频域资源组的。同样如上述举例,第一指示信息有两个字段:{BWP0,BWP1}和{BWP2,BWP3},终端根据第一指示信息可以确定BWP0和BWP1为同一组,BWP2和BWP3为同一组。这样,终端可以根据带宽部分的组号,来确定可用频域资源和不可用频域资源,相同组内的带宽部分可以采用一个窄带滤波器来处理,从而能够避免上下行的干扰。
