本申请实施例涉及通信领域,尤其涉及一种参数配置方法及装置。
带宽部分(bandwidth part,BWP)可以是***带宽的一部分。第一类BWP中包括连续的频域资源。终端设备在和网络设备进行数据传输时,可以根据该第一类BWP的参数在该第一类BWP的频域位置上传输数据。目前,为了提高离散频谱下数据传输的频谱效率,现有通信协议定义了包括离散频域资源的第二类BWP,从而,使得终端设备可以在非连续的频域资源上进行数据传输,以提高频谱效率。但是,现有技术并未规定在离散频谱下如何确定第二类BWP的频域位置以及参数的技术方案。

在本申请实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
为了下述各实施例的描述清楚简洁,首先给出相关技术的简要介绍:
BWP可以是***带宽的一部分。在一些场景中,BWP也可以称为带宽资源、载波带宽部分(carrier bandwidth part,CBWP)、频率资源部分、部分频率资源、载波带宽部分、子带(subband)或窄带(narrowband)等。
图1为本申请实施例提供的一种***带宽中的带宽资源的示例图。如图1所示,***带宽包括3个不同的带宽资源,即带宽资源0、带宽资源1和带宽资源2。带宽资源0、带宽资源1和带宽资源2中的任意一个可以认为是上述的带宽部分。在实际应用中,***带宽可以包括多个带宽资源。对于不同的带宽资源,以带宽资源0和带宽资源1为例,带宽资源0与带宽资源1的频域资源可以部分或全部重叠,或完全不重叠。示例性地,在基于正交频分复用(orthogonal frequency division multiplexing,OFDM)技术的通信***中,带宽资源0和带宽资源1的频域资源完全重叠,但是帧结构(比如子载波间隔(subcarrier spacing,SCS)和/或循环前缀(cyclic prefix,CP)长度) 不同,本申请实施例对此不作限定。
在频域上,可以将每个配置不同numerology的子带称为一个BWP。numerology定义为子载波间隔和循环前缀的组合。根据BWP包括的频域资源的类型可以将BWP分为两种类型。两种类型包括第一类BWP和第二类BWP。在一些场景中,频域资源还可以称为频率资源。
第一类BWP包括连续的频域资源,频域资源的单位可以是子载波、资源块(resource block,RB)、资源块组(resource block group,RBG)、或赫兹等。其中,一个RB中可以包括正整数(例如12)个子载波,一个RBG中可以包括正整数个RB。图2为本申请实施例提供的一种时频资源格(resource grid)的结构示例图。其中,在频域上的最小单位是子载波,相邻子载波的子载波间隔可以是15kHz、30kHz、60kHz、120kHz、240kHz或480kHz等。在时域上的最小单位是符号,一个或多个符号可以包括于一个时隙(slot)中,一个时隙可以为0.5毫秒(millisecond,ms)或1ms等。不同的子载波间隔下,时隙的长度可以不同也可以相同,本申请不做限制。不同的子载波间隔下,时隙中包括的符号个数可以不同也可以相同,本申请不做限制。时频资源格中的每一个小方格代表一个资源粒子(resource element,RE),一个RE在频域上的带宽为一个子载波,比如可以是15kHz,即与SCS相同,在时域上为一个OFDM符号的长度。频域上12个连续的子载波可以包括于一个资源块(resource block,RB)。两个slot可以包括于一个子帧中。或者,在不同的子载波间隔下,时隙与子帧的对应关系也可以不同。例如,普通循环前缀(normal cyclic prefix,NCP)情况下,对于15kHz子载波间隔,一个slot中可以包括7个OFDM符号或14个符号。如表1所示。当子载波间隔是15kHz时,一个时隙可以包括14个符号,一个无线帧可以包括10个时隙,一个子帧可以包括1个时隙。当子载波间隔是30kHz时,一个时隙可以包括14个符号,一个无线帧可以包括20个时隙,一个子帧可以包括2个时隙。当子载波间隔是60kHz时,一个时隙可以包括14个符号,一个无线帧可以包括40个时隙,一个子帧可以包括4个时隙。当子载波间隔是120kHz时,一个时隙可以包括14个符号,一个无线帧可以包括80个时隙,一个子帧可以包括8个时隙。当子载波间隔是240kHz时,一个时隙可以包括14个符号,一个无线帧可以包括160个时隙,一个子帧可以包括16个时隙。
表1
扩展循环前缀(extended cyclic prefix,ECP)情况下,对于60kHz子载波间隔,一个slot中可以包括6个OFDM符号或12个符号。比如,对于60kHz子载波间隔,一个无线帧可以包括40个时隙,一个子帧可以包括4个时隙。每个OFDM符号可以 包括数据部分和CP。
示例性地,第五代移动通信(the fifth generation telecommunication,5G)新空口(new radio,NR)***中,网络设备在一个服务小区中最多可以为终端设备配置4个第一类BWP,可以激活其中一个第一类BWP用于进行数据传输。终端设备在激活的第一类BWP上进行数据的收发。第一类BWP可以是定义在一个载波上的连续的RB资源,即一个第一类BWP的资源位于一个载波资源内。图3为本申请实施例提供的一种第一类BWP的结构示例图。
第二类BWP还可以称为X-BWP、BWP聚合(BWP bundle)、BWP集合(BWP set)、或BWP组(BWP group)。第二类BWP中包括N段频域资源,N为正整数,N大于或等于2。例如,N段频域资源可以是N个第一类BWP,即第二类BWP中包括N个第一类BWP。
需要说明的是,对于第二类BWP,N段频域资源可以是非连续的或者离散的。其中,离散的频域资源还可以描述为离散频谱。可理解的,非连续的N段频域资源中的任意两段频域资源均不连续。或者,N段频域资源中包括至少有两段频域资源不连续。另外,非连续的N段频域资源可以是位于一个成分载波(component carrier,CC)中,也可以是位于多个CC中。成分载波也可称为载波。第二类BWP中可以包含多个CC的资源,通过第二类BWP传输的数据可以在非连续的频域资源上传输,或者也可以在多CC上传输。在多个CC上传输时,实现了在离散频谱下的跨CC的数据传输,同时,相对使用多个第一类BWP进行数据传输的设计,调度开销较大的情况下,有效地降低了DCI中的指示开销。其中,在本申请实施例中,传输可以包括上行传输和/或下行传输,例如传输可以包括网络设备向终端设备发送信号,和/或包括终端设备向网络设备发送信号。图4为本申请实施例提供的一种第二类BWP的结构示例图。可选的,N段频域资源中的两段频域资源可能重叠。图5为本申请实施例提供的频域资源重叠的结构示例图。
在本申请实施例中,离散频谱可以是多段非连续的频谱资源。例如,运营商在低频段有很多离散频谱。以运营商A在时分双工(time division duplexing,TDD)1.8GHz频段为例,其中为长期演进(long term evolution,LTE)与NR配置了共享的7.5MHz连续频谱,还可以为NR另外配置5MHz连续频谱,对NR可以认为等效配置了12.5MHz的带宽。然而,对于NR,这7.5MHz和5MHz频谱之间还有5MHz频谱为运营商B占用。图6为本申请实施例提供的一种离散频谱的结构示例图,其中,比如在NR使用的频域资源间还有LTE使用的频域资源和空闲的频域资源。
为了解决在离散频谱下如何确定第二类BWP的频域位置以及参数的问题,本申请实施例提供一种带宽部分配置方法,其基本原理是:对于第二类BWP的参数,可以根据参数确定规则确定第二类BWP的参数值,其中,参数确定规则是根据第二类BWP的参数类型确定的。并且对于第二类BWP的资源,确定第二类BWP的资源配置,根据第二类BWP的资源配置确定第二类BWP的资源位置。其中,资源配置包括:至少一个参考点、至少一个第二偏移offset2和N个频域资源信息。N个频域资源信息对应于N段频域资源,第二类BWP中包括N段频域资源,N为正整数,N大于或等于2。该方法可应用于终端设备,或者该方法可应用于可以支持终端设备实现该方法 的通信装置,例如该通信装置包括芯片***,或者,该方法可应用于网络设备,或者该方法可应用于可以支持网络设备实现该方法的通信装置,例如该通信装置包括芯片***。从而,使得网络设备或终端设备可以根据本申请实施例提供的带宽部分配置方法在离散频谱下确定第二类BWP的频域位置以及参数,根据第二类BWP的参数值,在第二类BWP的频域位置上接收或发送数据,有效地提高了离散频谱的利用率,并提高了***性能。
下面将结合附图对本申请实施例的实施方式进行详细描述。
图7示出的是可以应用本申请实施例的通信***的简化示例图。参见图7,该通信***可以包括:一个或多个终端设备701和网络设备702。在实际应用中,每个终端设备701与网络设备702之间的连接为无线连接。终端设备通过无线通信技术与网络设备进行通信。
本申请实施例提供的技术方案可以应用于通信设备间的无线通信。通信设备间的无线通信可以包括:网络设备和终端设备间的无线通信、网络设备和网络设备间的无线通信以及终端设备和终端设备间的无线通信。其中,在本申请实施例中,术语“无线通信”还可以简称为“通信”,术语“通信”还可以描述为“数据传输”、“信息传输”或“传输”。
其中,终端设备701可以是能够接收基站调度和指示信息的无线终端设备,无线终端设备可以是指向用户提供语音和/或数据连通性的设备,或具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端设备可以经无线接入网(radio access network,RAN)与一个或多个核心网或者互联网进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)、计算机和数据卡,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,无线终端设备可以是个人通信业务(personal communication service,PCS)电话、无绳电话、会话发起协议(session initiation protocol,SIP)话机、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)等设备。无线终端设备也可以称为***、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point,AP)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户站(subscriber station,SS)、用户端设备(customer premises equipment,CPE)、用户设备(user equipment,UE)等。作为一种实施例,图7中所示的终端设备可以为手机。
网络设备702可以是无线通信的基站(base station,BS)或基站控制器等。也可以称为无线接入点,收发站,中继站,小区,发送接收点(transmit and receive port,TRP)等等。网络设备702可以是一种部署在无线接入网中用以为终端设备701提供无线通信功能的装置,其主要功能可以包括如下一个或多个功能:进行无线资源的管理、互联网协议(internet protocol,IP)头的压缩及用户数据流的加密、用户设备附着时进行移动管理实体(mobility management entity,MME)的选择、路由用户面数据至服务网关(service gateway,SGW)、寻呼消息的组织和发送、广播消息的组织和 发送、以移动性或调度为目的的测量及测量报告的配置等等。网络设备702可以包括各种形式的蜂窝基站、家庭基站、小区、无线传输点、宏基站、微基站、中继站、无线接入点等等。在采用不同的无线接入技术的***中,具备网络设备功能的设备的名称可能会有所不同。例如,在5G***或NR中,称为5G基站(generation Node B,gNB)等等,在无线本地接入***中,称为接入点。
需要说明的是,对于5G***,在一个NR基站(NR-NB或gNB)下,可能存在一个或多个发送接收点(transmission reception point,TRP),该一个或多个TRP属于同一个小区。另一种场景下,网络设备702还可以包括中心单元(central unit,CU)和分布单元(dsitribute unit,DU)。在一个CU下,可以存在多个DU。每个DU和终端设备都可以使用本申请实施例所述的方法。CU-DU分离场景和多TRP场景的区别在于,TRP可以是一个射频单元或一个天线设备,而DU中可以实现协议栈功能,例如DU中可以实现物理层功能。
随着通信技术的演进,网络设备的名称可能会变化。此外,在其它可能的情况下,网络设备702可以是其它为终端设备701提供无线通信功能的装置。为方便描述,本申请实施例中,为终端设备701提供无线通信功能的装置称为网络设备702。

下面结合附图对终端设备和网络设备配置带宽部分中的参数配置方法进行详细阐述。当然,参数配置方法也可以由终端设备内置的芯片或网络设备内置的芯片执行,本申请实施例对此不作限定。
图10为本申请实施例提供的一种参数配置方法的流程图,如图10所示,该方法可以包括:
S1001、对于第二类BWP的参数,根据第二类BWP的参数类型确定参数确定规则。
在本申请实施例中,第二类BWP的参数可以包括BWP公共参数或BWP专用参数。BWP公共参数是指通过公共信息发送的参数,或者可以是为一组终端设备配置的参数。其中,一组终端设备中可以包括一个或多个设备,例如一组终端设备可以是小区中的所有终端设备或者小区中的部分终端设备。BWP公共参数可以由网络设备通过高层信令为终端设备指示。高层信令可以是无线资源控制(radio resource control,RRC)信令或媒体介入控制(media access control,MAC)层信令。例如,通过RRC信令中的BWP公共(bwp-common)域为终端设备指示。BWP公共参数可以是通过***消息广播给各终端设备,各终端设备收到的BWP公共参数是相同的。例如,针对物理下行控制信道(physical downlink control channel,PDCCH)、物理下行共享信道(physical downlink shared channel,PDSCH)、物理上行控制信道(physical uplink control channel,PUCCH)或物理上行共享信道(physical uplink shared channle,PUSCH)配置的公共参数可以是BWP公共参数。BWP专用参数是指网络设备通过专用信息或终端设备级别的信令为终端设备发送的参数,不同的终端设备参数值独立配置,不同的终端设备参数值可以相同也可以不同,本申请不作限制。BWP专用参数可以是每个BWP都可以配置的参数,不同BWP的专用参数可以不同也可以相同,本申请实施例不做限制。BWP专用参数可以由网络设备通过高层信令为终端设备指示。高层信令可以是RRC信令或MAC层信令。例如,通过RRC信令中的BWP专用(bwp-dedicated)域为终端设备指示。专用参数可以是通过RRC信令指示给终端设备,各终端设备收到的专用参数可以是相同的或不同的。示例的,针对PDCCH、PDSCH配置的专用参数可以是BWP专用参数。
在本申请实施例中,第二类BWP的参数类型用于区别两个不同的参数。可以理解的,两个功能不同的第二类BWP的参数可以视为两个不同的参数类型。在本申请实施例中,不同的第二类BWP的参数类型对应的参数确定规则可以是不同的也可以是相同的。
S1002、根据参数确定规则确定第二类BWP的参数值。
对于第二类BWP的参数,在根据第二类BWP的参数类型确定了参数确定规则后,可以根据参数确定规则确定该第二类BWP的参数的参数值。在本申请实施例中,参数确定规则还可以称为规则、参数规则或其它名称,本申请不作限制。
在本申请实施例中,第二类BWP的参数值可以是一个参数值,也可以是参数值的候选取值,其中所述候选取值可以是由多个参数值组成的。或者,参数值的候选取值可以表示为参数值列表。
在第一种可实现方式中,由于第二类BWP中包括N段频域资源,该N段频域资源可以是N个第一类BWP,因此,对于N段频域资源中每段频域资源可以配置BWP公共参数和BWP专用参数。参数确定规则可以是第一规则,即根据M段频域资源的参数值确定第二类BWP的参数值。M段频域资源是N段频域资源中包括的M段频域资源,M为大于等于1的整数,且小于或等于N。或者,M段频域资源是N段频域资源中包括的M-1段频域资源和主频域资源,或者,M段频域资源是N段频域资源中包括的M-1段频域资源和默认频域资源,或者,M段频域资源是N段频域资源中包括的M-1段频域资源和用于初始接入的频域资源,M为大于等于1的整数。
可理解的,当M=N时,即根据第二类BWP中包括的N段频域资源的参数值确定第二类BWP的参数值。示例的,一个第二类BWP中包括第一段频域资源和第二段频域资源共两段频域资源。此时,可以根据第一段频域资源的参数值和/或第二段频域资源的参数值确定该第二类BWP的参数值。
可理解的,当M<N时,即根据第二类BWP中包括的N段频域资源中的部分频域资源的参数值确定第二类BWP的参数值。示例的,一个第二类BWP中包括第一段频域资源、第二段频域资源和第三段频域资源共三段频域资源。此时,可以根据第一段频域资源的参数值和第二段频域资源的参数值确定该第二类BWP的参数值。或者,根据第一段频域资源的参数值和第三段频域资源的参数值确定该第二类BWP的参数值。或者,根据第二段频域资源的参数值和第三段频域资源的参数值确定该第二类BWP的参数值。
需要说明的是,具体根据第二类BWP中包括的N段频域资源中哪几段频域资源的参数值确定第二类BWP的参数值可以是预配置的,也可以是根据预设规则确定,也可以是基站通过信令告知终端设备的。
因此,第二类BWP的参数值可以根据至少两个频域资源参数值确定。
可选地,根据预设规则确定根据第二类BWP中包括的N段频域资源中哪几段频域资源的参数值确定第二类BWP的参数值时,该预设规则可以是包括确定M的值,和确定M段频域资源是哪几段频域资源。
可选的,所述确定出的M段频域资源中的任意一个可以是该第二类BWP包含的频域资源,也可以是该第二类BWP中不包含的频域资源,比如可以是初始接入的频 域资源,主频域资源或默认频域资源等。
关于确定M的值,可以是根据如下方法中的至少一项确定:
1)可以是预定义的,比如规定为该第二类BWP包含的频域资源的个数,或者为该第二类BWP包含的频域资源的个数+1(比如如果第二类BWP不包含初始接入频域资源或主频域资源或默认频域资源时,可以除了根据包含的频域资源的参数确定,也可以根据不包含的频域资源的参数确定)。
2)预定义的个数,比如协议预定义为M个频域资源,M可以为正整数。
3)根据基站的指示,比如基站可以指示M个频域资源,M可以为正整数。
关于确定M段频域资源是哪几段频域资源,可以是根据如下方法确定:
1)确定频域资源的标识,根据第二类BWP中包含的频域资源确定,比如如果第二类BWP包含的频域资源的个数为N,则即根据该N个频域资源的参数该第二类BWP的参数。
2)如果确定的M的值与第二类BWP包含的频域资源的个数不同,则可以按照如下方式确定:
根据频域资源的标识大小确定频域资源,比如如果第二BWP包含的频域资源为频域资源X1,频域资源X2,频域资源X3。如果确定的M的值小于3,则可以根据频域资源标识的大小确定哪些频域资源。比如以频域资源标识小的为准,如果X1<X2<X3,则根据频域资源X1的参数值,频域资源X2的参数值确定该第二BWP的参数值。比如以频域资源标识大的为准,如果X1<X2<X3,则根据频域资源X2的参数值,频域资源X3的参数值确定该第二BWP的参数值。
3)根据基站的指示,比如基站可以指示M个,M可以为正整数。
确定了第二类BWP的参数值与哪些频域资源的参数值相关,可以按照本申请中的方法确定参数值。
需要说明的是,对于终端设备而言,终端设备可以预先配置N段频域资源的参数值以及N段频域资源对应的标识,在根据M段频域资源的参数值确定第二类BWP的参数值之前,可以接收网络设备发送的M个频域资源标识,根据M个频域资源标识获取M段频域资源的参数值,M个频域资源标识对应的频域资源为终端设备预先配置的N段频域资源中的频域资源。终端设备也可以接收网络设备发送的M段频域资源的参数值。
另外,除了根据第二类BWP中包括的频域资源的参数值确定第二类BWP的参数值之外,还可以仅根据第二类BWP中不包括的频域资源的参数值确定第二类BWP的参数值,例如,终端设备可以根据用于初始接入的频域资源的参数值、主频域资源的参数值或默认频域资源的参数值确定第二类BWP的参数值。其中,该场景中,用于初始接入的频域资源的参数值、主频域资源的参数值或默认频域资源的参数值确定第二类BWP的参数值不包括于第二类BWP中。
在第二种可实现方式中,参数确定规则可以是第二规则,即终端设备根据频域资源的属性确定第二类BWP的参数值。
本申请实施例中,频域资源的属性可以是指该频域资源是否为用于初始接入的频域资源,或者,该频域资源是否为主频域资源,或者,该频域资源是否为默认频域资 源。
例如,终端设备根据用于初始接入的频域资源的参数值确定第二类BWP的参数值,或者,根据主频域资源或预配置的频域资源对应的参数值确定第二类BWP的参数值。用于初始接入的频域资源可以是指终端设备进行同步和/或接入,或,接收同步信号,或,用于传输***信息块(system information block,SIB)1的频域资源。比如BWP的标识为0的BWP可以为用于初始接入的频域资源。
在本申请实施例中,主频域资源可以是指用于传输PDCCH的频域资源,或者,主频域资源可以是包括PDCCH的公共搜索空间的频域资源。SIB1用于传输***信息,终端设备可以根据SIB1获取进行小区接入有关的参数或信息。
需要说明的是,根据用于初始接入的频域资源的参数值、主频域资源的参数值或默认频域资源的参数值确定第二类BWP的参数值时,所述用于初始接入的频域资源、主频域资源或默认频域资源可以是不属于该第二类BWP内的频域资源,也可以是属于该第二类BWP内的频域资源,本申请不做限制。假设第二类BWP包括第一段频域资源和第二段频域资源共两段频域资源。例如,若第一段频域资源为用于初始接入的频域资源,将第一段频域资源的对应的参数值确定为第二类BWP的参数值。若第二段频域资源为用于初始接入的频域资源,将第二段频域资源的对应的参数值确定为第二类BWP的参数值。
可选的,还可以根据第二类BWP中不包括的频域资源的参数值和第二类BWP中包括的频域资源的参数值共同确定第二类BWP的参数值。
本申请实施例提供的参数配置方法,使得网络设备或终端设备可以在离散频谱中确定第二类BWP的参数,根据第二类BWP的参数值,在第二类BWP的频域位置上接收或发送数据,有效地提高了离散频谱的利用率,并提高了***性能。
对于第一种可实现方式,根据M段频域资源的参数值确定第二类BWP的参数值具体地可以包括以下实现方式。

示例的,一个第二类BWP中包括两段频域资源,第一段频域资源的标识为0,第二段频域资源的标识为1。比较第一段频域资源的标识和第二段频域资源的标识,由于第二段频域资源的标识大于第一段频域资源的标识,将第二段频域资源的参数值确定为该第二类BWP的参数值,即终端设备或网络设备通过该第二类BWP的频域资源发送或接收数据时,使用该第二类BWP中包括的第二段频域资源的参数值。
可选地,第二类BWP的参数或参数类型可以包括数据加扰标识(data scrambling identity),本申请实施例中数据加扰标识可以用于根据数据加扰标识确定数据加扰序 列的初始值,进而生成数据加扰序列。例如,一个第二类BWP中包括两段频域资源,第一段频域资源配置的数据加扰标识为D1,第二段频域资源配置的数据加扰标识为D2。在终端设备或网络设备使用该第二类BWP的频域资源发送或接收数据时,使用该第二类BWP中包括的第二段频域资源的参数值的情况下,终端设备或网络设备可以使用第二段频域资源配置的数据加扰标识,即可以是D2。具体的数据加扰标识的取值可以参考现有技术的介绍或其演进,本申请实施例对此不作限定。
可选地,第二类BWP的参数或参数类型可以包括资源块组(resource block group,RBG)大小。RBG大小是指RBG中包含的RB的个数,比如2,4,8等正整数。RBG大小可以与下行***带宽或者BWP的带宽相关等,也可以是网络设备配置给终端设备的。在资源分配时频域上可以是以RB为单位,也可以是以RBG为单位。配置信息RBG大小(比如rbg-size)可以用于指示在资源分配类型0下终端设备或网络设备使用的RBG的大小,例如,可以使用配置1的大小或配置2的大小。例如,如表2所示,在不同的BWP带宽下,可以使用的配置1或配置2下对应的RBG大小。
表2
BWP的大小/带宽 | 配置1 | 配置2 |
1–36 | 2 | 4 |
37–72 | 4 | 8 |
73-144 | 8 | 16 |
145-275 | 16 | 16 |
例如,一个第二类BWP中包括两段频域资源,第一段频域资源配置的RBG大小对应配置1,第二段频域资源配置的RBG大小对应配置2。在终端设备或网络设备使用该第二类BWP的频域资源发送或接收数据时,使用该第二类BWP中包括的第二段频域资源的参数值的情况下,终端设备或网络设备可以使用第二段频域资源配置的RBG大小,即可以是根据第二段频域资源的带宽和配置2确定的RBG大小。具体的RBG大小的配置可以参考现有技术的介绍或其演进,本申请实施例对此不作限定。

示例的,一个第二类BWP中包括两段频域资源,第一段频域资源的标识为0,第二段频域资源的标识为1。比较第一段频域资源的标识和第二段频域资源的标识,由于第一段频域资源的标识小于第二段频域资源的标识,将第一段频域资源的参数值确定为该第二类BWP的参数值,即终端设备或网络设备使用该第二类BWP的频域资源发送或接收数据时,使用该第二类BWP中包括的第一段频域资源的参数值。
可选地,第二类BWP的参数或参数类型为资源块组(resource block group,RBG)大小。例如,一个第二类BWP中包括两段频域资源,第一段频域资源配置的RBG大小对应表1中的配置1,第二段频域资源配置的RBG大小对应表1中的配置2。在终 端设备或网络设备使用该第二类BWP的频域资源发送或接收数据时,使用该第二类BWP中包括的第一段频域资源的参数值的情况下,终端设备或网络设备可以使用第一段频域资源配置的RBG大小,即可以是根据第一段频域资源的带宽和配置1确应的RBG大小。
可选地,第二类BWP的参数或参数类型为数据加扰标识。例如,一个第二类BWP中包括两段频域资源,第一段频域资源配置的数据加扰标识为D1,第二段频域资源配置的数据加扰标识为D2。在终端设备或网络设备使用该第二类BWP的频域资源发送或接收数据时,使用该第二类BWP中包括的第一段频域资源的参数值的情况下,终端设备或网络设备可以使用第一段频域资源配置的数据加扰标识,即可以是D1。

S1302、根据M段频域资源的标识中的特定标识对应的频域资源的参数值确定第二类BWP的参数值。
其中,特定标识可以是为终端设备和网络设备预配置的标识,例如,可以是协议预先设定的。例如,将M段频域资源的标识中的第一个标识对应的频域资源的参数值确定为第二类BWP的参数值。示例的,一个第二类BWP中包括三段频域资源,第一段频域资源的标识为0,第二段频域资源的标识为1,第三段频域资源的标识为2。将三段频域资源的标识中的第一个标识对应的频域资源的参数值确定为第二类BWP的参数值。例如,第二类BWP的参数为数据加扰标识,终端设备或网络设备使用本段落中描述的一个第二类BWP的频域资源发送或接收数据时,使用该第二类BWP中包括的第一段频域资源配置的数据加扰标识。
或者,对于终端设备而言,特定标识可以是从网络设备接收的标识。具体的,网络设备可以发送指示信息指示所述特定标识,终端设备根据所述指示信息确定特定标识,进而根据特定标识对应的频域资源的参数值确定第二类BWP的参数值。所述指示信息可以是通过高层信令发送的,也可以是通过物理层信息发送的。
或者,对于终端设备而言,特定标识可以是初始接入的频域资源的标识。
方法二,可以根据M段频域资源的参数值从M段频域资源的M个参数值中确定所述第二类BWP的参数值。图14为本申请实施例提供的一种参数配置方法的流程图,如图14所示,该方法可以包括:
S1401、对于第二类BWP的参数,根据第二类BWP的参数类型确定参数确定规则,参数确定规则为第一规则。
S1402、根据M段频域资源的参数值中最大的参数值确定第二类BWP的参数值。
示例的,第二类BWP的参数或参数类型为PDSCH聚合因子(pdsch-aggregation factor)。本申请实施例中,PDSCH聚合因子用于指示一次调度中PDSCH连续传输的时隙个数。比如如果聚合因子的取值为2,表示PDSCH可以在2个时隙上传输。
假设一个第二类BWP中包括第一段频域资源和第二段频域资源共两段频域资源。第一段频域资源配置的聚合因子为f1,第二段频域资源配置的聚合因子为f2。具体的 聚合因子的取值可以参考现有技术的介绍或其演进,本申请实施例对此不作限定。若第一段频域资源配置的聚合因子f1大于第二段频域资源配置的聚合因子f2,此时,终端设备或网络设备可以使用第一段频域资源配置的聚合因子,即可以是f1,用于在该一个第二类BWP中传输PDSCH。
图15为本申请实施例提供的一种参数配置方法的流程图,如图15所示,该方法可以包括:
S1501、对于第二类BWP的参数,根据第二类BWP的参数类型确定参数确定规则,参数确定规则为第一规则。
S1502、根据M段频域资源的参数值中最小的参数值确定第二类BWP的参数值。
示例的,第二类BWP的参数或参数类型为PDSCH聚合因子。

图16为本申请实施例提供的一种参数配置方法的流程图,如图16所示,该方法可以包括:
S1601、对于第二类BWP的参数,根据第二类BWP的参数类型确定参数确定规则,参数确定规则为第一规则。
S1602、根据M段频域资源的参数值的平均值确定第二类BWP的参数值。
示例的,第二类BWP的参数为或参数类型PDSCH聚合因子。
假设一个第二类BWP包括第一段频域资源和第二段频域资源共两段频域资源。第一段频域资源配置的聚合因子为f1,第二段频域资源配置的聚合因子为f2。终端设备或网络设备可以使用第一段频域资源配置的聚合因子和第二段频域资源配置的聚合因子的平均值作为该第二类BWP的聚合因子,即可以是(f1+f2)/2,用于在该第二类BWP中传输PDSCH。
可选地,也可以是对M段频域资源的参数值的平均值乘以比例因子作为第二类BWP的聚合因子、或也可以是将候选取值中与M段频域资源的参数值的平均值的差异最小的候选取值作为第二类BWP的聚合因子、或对M段频域资源的参数值的平均值进行向上取整或向下取整后的参数值作为第二类BWP的聚合因子。例如,第二类BWP的聚合因子的候选取值为1、2、4或8时,对于上述一个第二类BWP,则可以将1、2、4和8中与f1和f2的平均值的差值最小的值作为该第二类BWP的聚合因子,或者可以将1、2、4和8中与f1和f2的平均值的差值的绝对值最小的值作为该第二类BWP的聚合因子。例如,假设f1=2,f2=8,(f1+f2)/2=5,5与4的差值最小或差值的绝对值最小,因此,该第二类BWP的聚合因子为4,用于在该第二类BWP中传输PDSCH。
方法三,可以根据M段频域资源的参数值的候选取值确定第二类BWP的参数值的候选取值。图17为本申请实施例提供的一种参数配置方法的流程图,如图17所示,该方法可以包括:

S1702、根据M段频域资源的参数值的候选取值的并集确定第二类BWP的参数值的候选取值。
示例的,第二类BWP的参数或参数类型为PDSCH的时域资源分配。本申请实施例中,时域资源分配列表(pdsch-time domain allocation list)用于指示PDSCH的候选的时域资源分配集合。例如,网络设备可以通过高层信令为终端设备配置一个或多个候选的时域资源分配,并可以在DCI中指示候选中的一个作为网络设备为该终端设备配置的PDSCH时域资源分配。
假设一个第二类BWP包括第一段频域资源和第二段频域资源共两段频域资源,第一段频域资源配置的时域资源分配列表包括x1~x16行,第二段频域资源配置的时域资源分配列表包括y1~y16行。具体的时域资源分配列表包括的行数可以参考现有技术或其演进的介绍,本申请实施例对此不作限定。本申请实施例中,时域资源分配列表的一行可以对应一个具体的时域资源分配。当然,时频资源列表也可以以列的方式存在,例如时域资源分配列表的一列可以对应一个具体的时域资源分配。假设第一段频域资源配置的时域资源分配列表包括的x1~x8行和第二段频域资源配置的时域资源分配列表包括的y1~y8相同。此时,第二类BWP的时域资源分配列表的候选取值可以包括x1~x8行或y1~y8行,x9~x16和y9~y16。
需要说明的是,如果候选行数超出时域资源分配列表可以包括的行数,则可以根据以下方法确定第二类BWP的时域资源分配列表包括的行数。第一、可以每个频域资源的参数值的候选取值各取一半。例如,如果要求的最大行数为16行,则上述一个第二类BWP的时域资源分配列表可以包括第一段频域资源配置的时域资源分配列表包括的x1~x8行和第二段频域资源配置的时域资源分配列表包括的y1~y8。第二、除了取值重复的行数,每段频域资源配置的时域资源分配列表包括的剩余的行数各取一半。例如,上述一个第二类BWP的时域资源分配列表可以包括x1~x8或y1~y8、x9~x12和y9~y12。
在本申请实施例中,当第二类BWP的参数值的候选取值是根据至少两段频域资源的参数值的候选取值组合而成时,组合得到的候选取值的排序需要确定,或者可以称为对该多个候选取值进行标识。当网络设备通过DCI为终端设备指示第二类BWP的参数值时,可以指示该多个候选取值中的至少一个候选取值的标识,终端设备根据该至少一个候选取值的标识确定网络设备为其配置的参数值。
可选地,第二类BWP的参数值的候选取值的排序可以是按照M段频域资源的标识确定,或按照M段频域资源的属性确定。
具体的,可以是标识小的排序在前,标识大的排序在后;或者标识小的排序在后,标识大的排序在前,或者其他排序,具体的,本申请对此不做限定。比如一个第二类BWP包括第一段频域资源和第二段频域资源共两段频域资源。第一段频域资源的标识为X1,第二段频域资源的标识为X2,如果X1<X2,按照标识小的排序在前,标识大的排序在后,则该第二类BWP的参数值的候选取值的排序为频域资源X1对应的参数值的候选取值在前,频域资源X2对应的参数值的候选取值在后。例如表3所示,其 中表3的第3列为可选项。
表3

假设一个第二类BWP中包括第一段频域资源和第二段频域资源共两段频域资源。第一段频域资源配置的时域资源分配列表包括x1~x16行,第二段频域资源配置的时域资源分配列表包括y1~y16行。假设第一段频域资源配置的时域资源分配列表包括的x1~x4行和第二段频域资源配置的时域资源分配列表包括的y10~y14行相同,第一段频域资源配置的时域资源分配列表包括的x12~x16行和第二段频域资源配置的时域资源分配列表包括的y4~y8行相同。此时,该第二类BWP的时域资源分配列表中的候选取值可以包括x1~x4行或10~y14,以及x12~x16行或y4~y8行。
在本申请实施例中,参数值的候选取值有时还可以称为参数的候选取值。
在本申请实施例中,当第二类BWP的参数的候选取值是根据至少两段频域资源的参数值的候选取值组合而成时,组合得到的候选取值的排序需要确定,或者可以称为对该多个候选取值进行标识。当网络设备通过DCI为终端设备指示第二类BWP的参数值时,可以指示该多个候选取值中的至少一个候选取值的标识,终端设备根据该至少一个候选取值的标识确定网络设备为其配置的参数值。
可选地,第二类BWP中的参数的候选取值的排序可以是按照频域资源的标识确定,或按照频域资源的属性确定。比如对于第二类BWP中的参数的候选取值所在的频域资源,根据该所在的频域资源的标识中的最小标识对应的频域资源中的参数的候选取值的排序确定,或者根据该所在的频域资源的标识中的最大标识对应的频域资源中的参数的候选取值的排序确定,或者根据特定标识对应的频域资源中的参数的候选取值的排序确定。示例的,对于上述一个第二类BWP,该第二类BWP的参数的候选 取值的排序可以是按照第一段频域资源中的排序,如表4的第一列和第二列所示;或者该第二类BWP的参数的候选取值的排序可以是按照第二段频域资源中的排序,如表4的第一列和第三列所示。
表4
可选的,通过该方法确定第二类BWP的参数值的候选取值,可以在第二类BWP中的频域资源上传输信号时各频域资源可以采用统一的时域资源分配进行数据传输,保证各频域资源的时域资源都是可用的。
在本申请实施例中,可选的,也可以从M段频域资源的参数值的候选取值中,每段频域资源的参数值的候选取值中各取一部分候选取值作为第二类BWP的参数值的候选取值。其中,进一步地,可以根据该M段频域资源的优先级确定所取的候选取值的数量或者比例。可选的,所述优先级,和/或参数的选取方法可以是协议预定义的,也可以是基站通过信令告知终端的。例如,根据频域资源的标识和/或频域资源的属性确定选取候选取值的优先级。比如,用于初始接入的频域资源(或主频域资源或默认频域资源)的优先级可以大于普通(normal)频域资源的优先级,或者,频域资源的标识小的优先级可以大于频域资源的标识大的优先级。例如,若M段频域资源中的一段频域资源为终端设备的初始接入频域资源(或主频域资源或默认频域资源),包括该M段频域资源的第二类BWP的时域资源分配列表的候选取值可以包括该一段频域资源配置的时域资源分配列表的部分或所有候选取值。
或者,在本申请实施例中,如果第二类BWP的时域资源分配列表的最大行数为X行,则可以在第二类BWP包括的每段频域资源中各取X/M行,或对X/M向上取整行或对X/M向下取整行,作为第二类BWP的时域资源分配列表的参数。或者,按照比例选取各段频域资源中的参数值。
在本申请实施例中,从一段频域资源的参数的候选取值中取部分或者全部候选取值,作为该一段频域资源所在的第二类BWP的参数的候选取值的部分或全部候选取值,还可以描述为:该一段频域资源所在的第二类BWP的参数的候选取值中,包括该一段频域资源的参数的候选值中的部分或者全部候选取值。
需要说明的是,也可以从M段频域资源中选择Q段频域资源的参数值,根据M段频域资源中Q段频域资源的参数值的候选取值的并集确定第二类BWP的参数值的候选取值。或者,根据M段频域资源中Q段频域资源的参数值的候选取值的交集确定第二类BWP的参数值的候选取值。Q为大于等于2的整数,且小于或等于M。
可选的,根据本申请实施例提供的方法,以第二类BWP的参数中的计算传输块大小(transmission block size,TBS)的开销配置为例对本申请实施例中的方法进行示意性说明。计算传输块大小的开销配置用于指示开销所占的RE数。比如计算传输块大小的开销参数的取值可以是0,6,8,12和18等其他正整数。当计算TBS时会根 据数据调度的时频资源减去开销所占的RE数计算TBS。
具体的,针对数据传输块大小配置的开销参数,假设第二类BWP包括两段频域资源,分别为第一段频域资源X1和第二段频域资源X2。如果频域资源X1配置的开销取值为o1,频域资源X2配置的开销取值为o2。具体的开销的取值可以是上面介绍中的取值中的至少一个,也可以是其他取值,具体的,不做限定。具体的,第二类BWP的参数的确定方法可以是如下方法中的至少一项:
方法1)根据频域资源的参数值中的最大值确定。
比如如果o1>o2,则第二类BWP的开销的参数值可以是o1。
通过上述方法1,可以使得在第二类BWP上进行数据传输时考虑各频域资源上的开销的最大值,可以使得传输数据时考虑所有不可用RE的开销,计算的TBS会偏小,码率降低,不至于超过最大码率而导致性能变差,缺点是传输的数据量变小。
方法2)根据频域资源的参数值中的最小值确定。
比如如果o1>o2,则第二类BWP的开销的参数值可以是o2。
通过上述方法2,可以使得在第二类BWP上进行数据传输时考虑各频域资源上的开销的最小值,可以使得传输数据时考虑最小的不可用RE的开销,计算的TBS会偏大,最大化的进行数据传输,提高数据吞吐量,缺点是码率变大,有可能会因为码率过大而导致性能变差。
方法3)根据至少两个频域资源的参数值的平均值或求和或乘以比例因子确定。
比如根据至少两个频域资源的参数值的平均值确定第二类BWP的参数值。比如(o1+o2)/2,或进一步向上取整或向下取整。或取平均值之后,如果规定的取值仅为6,8,12和16,可以将6,8,12和16中与(o1+o2)/2的差值的绝对值最小的值作为该第二类BWP的参数值,比如如果频域资源X1的参数值o1=6,频域资源X2的参数值o2=12,则(o1+o2)/2=9,9与8的差值最小或差值的绝对值最小,因此,该第二类BWP的参数值为8。即第二类BWP的开销参数值可以是(o1+o2)/2,或向上取整或向下取整,或者进一步取值之后找到最近的符合条件的取值。
比如根据至少两个频域资源的参数值的求和确定第二类BWP的参数值。比如o1+o2,或向上取整或向下取整。或取和之后,如果规定的取值仅为6,8,12和16。则找到与6,8,12和16的差值的绝对值最小的值作为该第二类BWP的参数值,比如如果频域资源X1的参数值o1=6,频域资源X2的参数值o2=12,则取和为18,18与18差值最小,因此第二类BWP的参数值为18。
比如根据至少两个频域资源的参数值乘以比例因子确定第二类BWP的参数值。比如o1*w1+o2*w2,或者(o1+o2)*w3,或可以进一步向上取整或向下取整。或乘以比例因子之后,如果规定的取值仅为6,8,12和16。则找到与6,8,12和16的差值的绝对值最小的值作为该第二类BWP的参数值。其中,比例因子w1,w2,w3取值为实数,比如可以是0.2,0.8,0.4等,比例因子的取值可以是协议预定义的,也可以是网络设备通过信令告知终端设备的。比如如果频域资源X1的参数值o1=6,频域资源X2的参数值o2=12,则以w3为0.2为例,(o1+o2)*0.2为18*0.2=3.6,3.6与6的差值最小或差值的绝对值最小,因此,第二类BWP的参数值为6。
即第二类BWP或BWP bundle或BWP group的开销参数值可以是o1*w1+o2*w2, 或者(o1+o2)*w3,或者进一步取值之后找到最近的符合条件的取值。
通过上述方法3,可以使得在第二类BWP上进行数据传输时充分考虑各频域资源上的开销的参数值,可以使得传输数据时考虑合理的不可用RE的开销,计算的TBS时会过大也不会太小,合理有效的进行数据传输,提高数据吞吐量。
方法4)根据至少两个频域资源的参数值确定。

图21为本申请实施例提供的一种资源配置方法的流程图,如图21所示,该方法可以包括:
S2101、确定第二类BWP的资源配置。
第二类BWP中包括N段频域资源,N为正整数,N大于或等于2。该N段频域资源中的一段频域资源可以是一个第一类BWP。在无线通信***中,例如5G标准的版本15(Release 15,R15)或其演进中,第一类BWP是一段连续的频域资源。第一类BWP的配置可以包括该第一类BWP的频率起始RB、带宽(bandwidth,BW)和对应的参数(numerology)。其中,带宽是指该第一类BWP包括的RB数,参数包括子载波间隔和循环前缀中至少一个。
在本申请实施例中网络设备可以通过如下三个偏移值(offset)为终端设备配置带宽部分。
第一偏移(offset1):终端设备根据参考频率位置(reference location)和相对于该参考频率位置的第一偏移(offset1)确定参考点A(reference point A),根据该参考点A确定公共RB的索引。其中,不同的子载波间隔SCS=2
μ×15kHz对应各自的公共RB索引,比如15kHz的RB0和RB1可以对应30kHz的RB0,而30kHz的RB0和RB1可以对应60kHZ的RB0,类似的,不同子载波间隔对应各自的公共RB索引,且不同的子载波间隔对应的公共RB的公共RB0的子载波0均包含该参考点A,公共RB从公共RB0按频率增大的方向编号。示例性地,对于主小区下行载波,参考频率位置根据终端设备接收的同步信号块的频率最低的RB确定;对于非配对频谱主小区上行载波,参考频率位置根据终端设备接收的同步信号块的频率最低的RB确定;对于配对频谱主小区上行载波,参考频率位置根据基站配置的频率位置确定,该频率位置可以对应一个绝对频点号(absolute radio frequency channel number,ARFCN);对于辅小区,参考频率位置根据基站配置的频率位置确定,该频率位置可以对应一个绝对频点号;对于增补上行载波,参考频率位置根据基站配置的频率位置确定,该频率位置可以对应一个绝对频点号。上述非配对频谱可以是在TDD场景下,上行载波和下行载波为同一载波,上行载波和下行载波为非配对频谱。上述配对频谱可以是在FDD场景下,上行载波和下行载波是两个载波,上行载波和下行载波为配对频谱。
第二偏移(offset2):终端设备根据参考点A或公共RB0以及相对于该参考点A或公共RB0的第二偏移,确定虚拟载波(virtual carrier)的最低RB位置,终端设备还可以根据网络设备配置的虚拟载波带宽确定虚拟载波,其中,虚拟载波也可以称为逻辑载波、终端设备特定载波、可用RB、可用带宽等。终端设备可以根据虚拟载波确定资源格、OFDM基带信号,放置RF收发器和/或进行滤波。示例性地,OFDM基带信号的生成根据虚拟载波的大小,即该虚拟载波中包含的RB个数确定,以频率连续的虚拟载波为例,假设该虚拟载波中包含
个RB,则OFDM基带信号可以表示为:
其中,
表示一个RB中包括的子载波个数,例如
k
0表示网络设备配置的子载波级偏移;Δf表示子载波间隔;N
CP,l表示第l个符号的CP长度;T
c表示预定义的时域单元,根据***支持的最大子载波间隔和FFT点数确定,例如***支持的最大子载波间隔为480kHz,FFT点数为4096,则T
c=1/(480·10
3·4096);t
start,l表示第l个符号的时域位置,或者和第0个符号之间的时域偏移。
第三偏移(offset3):BWP的最低RB位置相对于虚拟载波的最低RB位置的偏移,终端设备根据该偏移确定BWP的起始RB。进一步,可以配置BWP的带宽,进而终端设备可以根据起始RB和RB长度确定该BWP在载波中的位置。
在本申请实施例中,可选地,关于offset1、offset2和offset3的介绍可以参考5G标准协议或其演进。offset1、offset2和offset3可以用于第一类BWP。
