Description

一种资源指示的方法、设备及系统
本申请中要求在2017年05月05日提交中国专利局、申请号为201710314158.X、申请名称为“一种资源指示的方法、设备及系统”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
本申请涉及通信技术领域，特别涉及一种资源指示的方法、设备及系统。
背景技术
长期演进(Long Time Evolution，LTE)中，终端设备在初始接入时，通过接收物理广播信道(Physical Broadcast Channel，PBCH)的消息，确定下行的系统带宽，然后基站根据系统带宽为终端设备分配资源。具体的，在LTE中基站可以按照类型type0、type1和type2为终端设备分配资源，基站向终端设备分配的资源以资源块组(Resource Block Group RBG)为粒度，其中基站在按照type0和type1为终端设备分配资源时，是通过比特位图(bitmap)的方式指示给终端设备的，以type0为例，如果某个RBG分配给了终端设备，则在bitmap中相应的比特位上设置为1，否则设置为0。
而现有技术中终端设备和基站预先约定好RBG的大小与系统带宽的映射关系，如表0所示，因此终端设备根据系统带宽，基站发送的bitmap，则能够确定基站为终端设备分配的资源。

Figure PCTCN2018083233-appb-000001
然而，在新一代无线通信(New Radio，NR)中，终端设备通常情况下支持的最大带宽小于系统带宽或者载波带宽，因此受限于终端设备支持的最大带宽，无法按照LTE中的方式为终端设备分配资源，为了解决上述问题，在NR中提出两步资源分配方式，第一步基站给终端设备分配一段小于或等于终端设备支持的最大带宽的带宽，第二步就是基站和终端设备在分配的带宽中进行物理信道信息和/或物理信号信息的传输。有鉴于此，本申请提出了一种资源指示的方式，用于解决第一步中终端设备带宽分配的问题。

具体实施方式
下面结合附图对本申请实施例进行详细说明。
应理解，本申请实施例可以应用于但不限于多子载波间隔的通信系统，如NR系统、LTE系统等。
应理解，本申请实施例所涉及的网络设备，可以是基站，或者接入点，或者可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。当网络设备为基站时，基站可用于将收到的空中帧与网际协议(Internet Protocol，IP)分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。基站还可用于协调对空中接口的属性管理。例如，基站可以是GSM或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)中的节点B(NodeB)，还可以是LTE系统中的演进型基站(evolutional Node B，eNB)，本申请实施例并不限定。
应理解，本申请实施例中的终端设备可以为用于向用户提供语音和/或数据连通性的设备、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。终端还可以为无线终端，其中，无线终端可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)、或具有移动终端的计算机，例如，具有移动终端的计算机可以是便携式、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，无线终端还可以为个人通信业务(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。无线终端也可以称为系统、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(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)等，本申请实施例不做限定。
应理解，本申请实施例中的BP指的是频域上一段连续或非连续的带宽，其中这段连续或非连续的带宽在频域上小于或等于终端设备支持的最大带宽，可以用于物理信道信息或物理信号信息的传输，物理信道信息包括物理上下行控制信道信息和物理上下行共享信道 信息。示例的，如图1a所示，BP为整个通信系统带宽中的一段连续的带宽，如图1b所示，为本申请实施例BP为整个通信系统带宽中的非连续的带宽，具体的，如图1b所示的BP1和BP2部分组成BP，而BP1与BP2之间是非连续的。其中，需要说明的是，在本申请实施例中基站为不同终端设备分配的BP在频域上可以有重叠，示例的，如图1c所示，第一BP为基站为终端设备1分配的带宽，第二BP为基站为终端设备2分配的带宽。
为了表述方便，在本申请实施例中，以网络设备为基站举例进行详细说明，这仅是本申请实施例所举的例子，当网络设备为其它设备时，与网络设备为基站时类似，在此不再赘述。具体的，如图2所示，本申请实施例的通信系统架构图，包括基站和终端设备。
以图2所示的通信系统架构对本申请实施例的资源指示方法进行详细说明。
如图3所示，本申请实施例资源指示方法，包括：
步骤300，基站为终端设备分配BP，该BP中包括至少一个子BP，BP不大于终端设备所支持的最大带宽。
步骤310，基站向终端设备发送指示BP资源位置的第一消息，终端设备接收基站发送的第一消息，第一消息包括至少一个子BP的资源位置信息。
步骤320，终端设备根据至少一个子BP的资源位置信息，确定BP的资源位置。
其中，需要说明的是，在本申请实施例中子BP又可以被称之为迷你BP(mini BP)、BP单元(BP Unit)、BP子带等，本申请实施例中不对子BP的名称进行限定。其中，子BP是由一段连续的物理资源块(Physical Resource Block，PRB)组成，或者子BP是在频域上固定带宽的一个资源单元，或者子BP由一段连续的固定带宽的资源单元组成，子BP的大小不大于终端设备支持的最大带宽。在本申请实施例中子BP的大小指的是子BP在频域上所占用的带宽。
在本申请实施例中，由于BP是以子BP为粒度进行分配的，例如，基站给终端设备分配一个20MHz的BP，则可以通过为终端设备分配至少一个子BP来满足终端设备的需求，因此能够适应更灵活的资源分配需求和有助于减少信令的开销。
本申请实施例中基站可以按照如下方式配置至少一个子BP的大小，在至少一个子BP中的各个子BP的大小相同时，具体的：
示例一：
BP中包括的至少一个子BP的大小为第一子BP大小集合中包括的子BP大小，其中第一子BP大小集合中包括至少一个子BP大小，第一子BP大小集合对应第一载频范围，第一载频范围中包括基站与终端设备之间传输信号所使用的载频。例如，在LTE中，基站与终端设备之间传输信号所使用的载频为终端设备所在小区使用的载频。
需要说明的是，在示例一中，由于子BP集合与载频范围相对应，因此基站能够根据基站与终端设备之间传输信号所使用的载频来确定第一载频范围，从与第一载频范围对应的第一子BP大小集合中选择一个子BP大小来作为至少一个子BP的大小。例如：子BP大小与载频范围的对应关系如表1所示，其中载频用F表示，单位为千兆赫兹GHz：
表1
载频范围 0<F<6 6≤F<28 F≥28
子BP大小集合 {5兆赫兹MHz} {20MHz} {40MHz}
即如表1所示，载频范围为0<F<6GHz时，对应的子BP大小集合为{5MHz}，则子BP大小集合中包括的子BP大小为5MHz；载频范围为6GHz≤F<28GHz时，对应的子BP 大小集合为{20MHz}，则子BP大小集合中包括的子BP大小为20MHz；载频范围为F≥28GHz时，对应的子BP大小集合为{50MHz}，则子BP大小集合中包括的子BP大小为40MHz；当终端设备所在小区使用的载频为5GHz时，则第一载频范围为0<F<6GHz，则至少一个子BP的大小为5MHz，若基站为终端设备分配20MHz的BP，则需要为终端设备分配4个5MHz的子BP即可。
应理解，上述子BP大小集合与载频范围的对应关系仅为举例说明，本申请实施例中不对子BP大小集合与载频范围的具体对应关系进行限定。
在示例一中，载频范围包括的载频的个数可以为一个，也可以为多个，子BP大小集合中包括的子BP大小可以为一个，也可以为多个，本申请实施例中不做限定。
示例二：
BP中包括的至少一个子BP的大小为第一子BP大小集合中包括的子BP大小，其中第一子BP大小集合中包括至少一个子BP大小，第一子BP大小集合对应第一系统带宽范围，第一系统带宽范围中包括网络设备的系统带宽。示例的，在LTE中，网络设备的系统带宽为终端设备所在小区的系统带宽。
需要说明的是，在示例二中，由于子BP集合与系统带宽范围相对应，因此基站能够根据网络设备的系统带宽来确定第一载频范围，从与第一载频范围对应的第一子BP大小集合中选择一个子BP大小来作为至少一个子BP的大小。例如：子BP大小与系统带宽范围的对应关系如表2所示，其中系统带宽又称为载波带宽，用CBW表示，单位为MHz：
表2
系统带宽范围 0<CBW<100 100≤CBW<200 F≥200
子BP大小集合 {5MHz} {20MHz} {40MHz}
即如表1所示，系统带宽范围为0<CBW<100MHz时，对应的子BP大小集合为{5MHz}，则子BP大小集合中包括的子BP大小为5MHz；系统带宽范围为100MHz≤CBW<200MHz时，对应的子BP大小集合为{20MHz}，则子BP大小集合中包括的子BP大小为20MHz；系统带宽范围为CBW≥200MHz时，对应的子BP大小集合为{50MHz}，则子BP大小集合中包括的子BP大小为40MHz；当终端设备所在小区的系统带宽为150MHz时，则第一系统带宽范围为100≤CBW<200，则至少一个子BP的大小为20MHz，若基站为终端设备分配40MHz的BP，则需要为终端设备分配两个20MHz的子BP即可。
应理解，上述子BP大小集合与系统带宽范围的对应关系仅为举例说明，本申请实施例中不对子BP大小集合与系统带宽范围的具体对应关系进行限定。
在示例二中，系统带宽范围包括的系统带宽的个数可以为一个，也可以为多个，子BP大小集合中包括的子BP大小可以为一个，也可以为多个，本申请实施例中不做限定。
示例三：
BP中包括的至少一个子BP的大小为第一子BP大小集合中包括的子BP大小，其中第一子BP大小集合中包括至少一个子BP大小，第一子BP大小集合为预定义子BP大小集合。
需要说明的是，预定义子BP大小集合中可以包括一个子BP大小，也可以包括多个子BP大小，本申请实施例对此不做限定。例如预定义子BP大小集合为{5MHz}、或者预定义子BP大小集合为{5MHz，20MHz}等。
在上述示例一、示例二、示例三中，由于子BP的大小是公共的，至少两个终端设备 的子BP的大小是相同的，因而示例一、示例二和示例三配置子BP大小的方式为公共级的，因此，可以将子BP大小的配置方式预先配置到基站和终端设备中，以示例一为例，基站和终端设备中预先配置子BP大小集合与载频范围的对应关系，则基站在向终端设备发送了第一消息后，终端设备可以从预先配置子BP大小集合与载频范围的对应关系中查找到与自身所在小区使用的载频所在的载频范围对应的子BP大小集合，并根据确定子BP大小集合中子BP大小、和根据第一消息确定的BP的资源位置，来确定基站为终端设备分配的BP的资源位置。此外，示例二、示例三与示例一类似，在此不再一一赘述。
其中需要说明的是，当基站和终端设备中同时预先配置的对应关系中子BP大小集合中仅包括一个子BP大小，则基站无需向终端设备通知子BP大小，当预先配置的对应关系中子BP大小集合中包括多个子BP大小时，则基站需要向终端设备通知基站选择的至少一个子BP的子BP大小。
另一种可选的方式，将子BP大小配置到基站中，以示例一为例，将子BP大小集合与载频范围的对应关系预先配置到基站中，由基站通知给终端设备至少一个子BP的大小，具体的：基站向终端设备发送第一指示信息，该第一指示信息用于指示至少一个子BP的大小。
需要说明的是，具体的，第一指示信息可以承载在主信息块(Master Information Block，MIB)、或者剩余最小系统信息(Remaining Minimum System Information，RMSI)、或者系统信息块(System Information Block，SIB)，或者其他系统信息(Other system information，OSI)、或者无线资源控制(Radio Resource Control，RRC)信令，或媒体访问控制控制元素(Media Access Control Control Element,MAC CE)中通知给终端设备，示例的，当子BP集合中有两个子BP时，第一指示信息可以为1比特，例如第一子BP大小集合为{5MHz，20MHz}，通过比特0指示5MHz，通过比特1指示20MHz；当子BP集合中包括4个子BP时，第一指示信息可以为两比特等，此外，第一指示信息还可以为多比特，在此不做限定。
以LTE为例，在其它通信系统中与此类似，在此不再一一赘述。由于基于示例一、示例二和示例三配置子BP大小的方式，对于同一个小区的终端设备来说，子BP大小是相同的，如图4所示，在频域上将一段连续或非连续的资源按照子BP大小进行划分，并从该段连续或非连续的资源的低频域位置开始对子BP进行编号，由于子BP的编号是连续的，因此，在本申请实施例中可选的，至少一个子BP的资源位置信息可以为子BP的起始编号和结束编号，以图4为例，假设BP1为基站分配给终端设备1的BP，由于BP1中包括编号0到编号4的子BP，则BP1中子BP的起始编号为0，结束编号为4，为了节省信令开销，则可以向终端设备通知BP1中子BP的起始编号为0，结束编号为4。除此之外，至少一个子BP的资源位置还可以为子BP的起始编号和子BP的个数，以图3为例，假设BP2为基站分配给终端设备2的BP，由于BP2中包括编号为9到编号为12的子BP，则基站可以向终端设备指示子BP的编号9和子BP的个数4。或者一个BP中包括的子BP编号是非连续的，则至少一个子BP的资源位置还可以为上述编号的组合，以图4为例，编号6、7，以及编号14为基站为终端设备3分配的BP，则至少一个子BP的资源位置为编号6、编号7和编号14。
需要说明的是，至少一个子BP的资源位置信息不限于上述举例的方式，还可以为BP的起始频域位置和子BP的个数、或者，子BP的结束编号和子BP的个数等，在此不再一 一赘述。
针对示例一、示例二和示例三配置子BP大小的方式，本申请实施例由于基站还可以从任意一个PRB上开始为终端设备分配子BP，因此对子BP进行编号的方式还可以如图4所示，假设BP1为基站分配给终端设备1的BP，BP2为基站分配给终端设备2的BP，其中基站针对分配给终端设备1的子BP、和分配给终端设备2的子BP分别进行编号，在该种编号方式下，针对终端设备1的至少一个子BP的资源位置信息为起始频域位置1和子BP的个数5、针对终端设备2的至少一个子BP的资源位置信息为起始频域位置2和子BP的个数4。
另外，本申请实施例中基站还可以按照如下方式配置子BP的大小，具体的：
示例四：
至少一个子BP的大小为第二子BP大小集合中包括的子BP大小，第二子BP大小集合中包括至少一个子BP大小；第二子BP大小集合对应第一子带宽范围，第一子带宽范围中包括终端设备支持的最大带宽。
需要说明的是，在示例四中，终端设备支持的最大带宽是由终端设备上报给基站的。由于在示例四中子BP集合与终端设备支持的最大带宽的范围相对应，因此基站能够根据终端设备支持的最大带宽来确定第一带宽范围，从与第一子带宽范围对应的第二子BP集合中选择一个子BP大小来作为至少一个子BP的大小。例如，子BP大小集合与终端设备支持的最大带宽的对应关系如表3所示，其中终端设备支持的最大带宽可以用字母W表示。
表3
最大带宽(MHz) 0<W<100 100≤W<150 W≥150
子BP大小集合 {5MHz} {20MHz} {40MHz}
即如表3所示，在0<W<100MHz时，对应的子BP大小集合为{5MHz}，则子BP大小集合中包括的子BP大小为5MHz；在100MHz≤W<150MHz时，对应的子BP大小集合为{20MHz}，则子BP大小集合中包括的子BP大小为20MHz；在W≥150MHz时，对应的子BP大小集合为{50MHz}，则子BP大小集合中包括的子BP大小为40MHz；当终端设备支持的最大带宽为200MHz时，则第一子带宽范围为W≥150，则至少一个子BP的大小为40MHz。
若基站为终端设备分配80MHz的BP，则需要为终端设备分配2个40MHz的子BP即可。
应理解，上述子BP大小集合与终端设备支持的最大带宽的对应关系仅为举例说明，本申请实施例中不对子BP大小集合与终端设备支持的最大带宽的具体对应关系进行限定。
在示例四中，第一子带宽范围中包括的带宽的个数可以为一个，也可以为多个，子BP大小集合中包括的子BP大小可以为一个，也可以为多个，本申请实施例中不做限定。
示例五：
至少一个子BP的大小为第二子BP大小集合中包括的子BP大小，第二子BP大小集合中包括至少一个子BP大小；第二子BP大小集合对应第一子带宽范围，第一子带宽范围中包括终端设备向基站上报的带宽的大小。
需要说明的是，该终端设备上报的带宽，可以是终端设备在上行信息中，向基站发送期望的BP大小。
在示例五中，由于子BP大小集合与终端设备向基站上报的带宽的大小的范围相对应， 因此，基站能够根据终端设备上报的带宽的大小来确定第一子带宽范围，从与第一子带宽范围对应的第二子BP集合中选择一个子BP大小来作为至少一个子BP的大小。例如，子BP大小集合与终端设备上报的带宽的大小的对应关系如表4所示，其中终端设备上报的带宽的大小可以用字母BBW表示。
表4
BBW(MHz) 0<BBW<100 100≤BBW<200 W≥200
子BP大小集合 {5MHz} {20MHz} {40MHz}
即如表4所示，在0<BBW<100MHz时，对应的子BP大小集合为{5MHz}，则子BP大小集合中包括的子BP大小为5MHz；在100MHz≤BBW<200MHz时，对应的子BP大小集合为{20MHz}，则子BP大小集合中包括的子BP大小为20MHz；在BBW≥200MHz时，对应的子BP大小集合为{50MHz}，则子BP大小集合中包括的子BP大小为40MHz；当终端设备上报的BP的大小为100MHz时，则第一子带宽范围为100MHz≤BBW<200MHz，则至少一个子BP的大小为20MHz。
若基站接收到的终端设备上报的带宽的大小为100MHz，则需要为终端设备分配5个20MHz的子BP即可。
应理解，上述子BP大小集合与终端设备上报的带宽的大小的对应关系仅为举例说明，本申请实施例中不对子载波大小集合与带宽的大小的具体对应关系进行限定。
在示例五中，第一子带宽范围中包括的带宽的个数可以为一个，也可以为多个，子BP大小集合中包括的子BP大小可以为一个，也可以为多个，本申请实施例中不做限定。
针对示例四、示例五配置子BP大小的方式，由于不同的终端设备最大支持的带宽可能不同，或者不同的终端设备对BP的需求也是不同的，因此向基站上报的带宽的大小也会不同，而且同一终端设备针对不同的场景或业务也有可能导致向终端设备上报的带宽的大小不同，因此，为了使得终端设备能够获取到至少一个子BP的大小，可选的，基站向终端设备发送第二指示信息，该第二指示信息用于指示至少一个子BP的大小。
具体的，需要说明的是，具体的，第二指示信息可以承载在MIB、或者RMSI、或者SIB，或者OSI、或者RRC信令，或MAC CE中通知给终端设备，示例的，当子BP集合中有两个子BP时，第二指示信息可以为1比特，例如第一子BP大小集合为{5MHz、20MHz}，通过比特0指示5MHz，通过比特1指示20MHz；当子BP集合中包括4个子BP时，第二指示信息可以为两比特等，此外，第二指示信息还可以为多比特，在此不做限定。
由于通过示例四、示例五配置子BP大小的方式对不同的终端设备配置的子BP大小可能相同的，也可能是不同的，因此示例四、示例五配置子BP大小的方式是UE级的，因而BP的起始频域位置可以从任意一个PRB的边界开始，因此针对示例四和示例五来说，当子BP为在频域上连续的一段带宽时，对子BP的编码方式可以如图5所示，则至少一个子BP的资源位置信息为BP的起始频域位置和BP中包括的子BP的个数。当子BP为在频域上非连续的带宽时，至少一个子BP的资源位置信息可以为各段带宽的起始频域位置和各段带宽中子BP的个数等。在本申请实施例中不限定至少一个子BP的资源位置信息的具体实现方式。除此之外，当针对不同的终端设备采用连续编码的方式时，例如对终端设备1分配了3个子BP，则分别编码为1、2和3，当为终端设备2分配了2个子BP时，则依次编码为4和5，则至少一个子BP的资源位置信息的实现方式可以参见示例一、示例二 和示例三中至少一个子BP的资源位置信息的具体实现方式。
在示例四和示例五中，以LTE为例，在其它通信系统中与此类似，在此不再一一赘述。针对同一小区的不同的终端设备配置的子BP的大小可以是相同的，也可以是不同的，如图6所示，BP1为基站为终端设备1分配的BP，BP2为基站为终端设备2分配的BP。
需要说明的是，示例四中终端设备支持的最大带宽的范围与子BP大小集合的对应关系可以预先配置到终端设备和基站中，当子BP大小集合仅包括一个子BP大小时，基站无需通知终端设备子BP大小，而当子BP大小集合中包括多个子BP大小时，基站需要通知终端设备子BP大小。
另外，示例四和示例五中，鉴于终端设备上报的支持的最大带宽、或者带宽的大小是针对各个终端设备的，因此通常情况下，将示例四和示例五中子BP大小集合的对应关系预先配置到基站中，由基站选择的至少一个子BP的大小后通知给终端设备。
此外，当终端设备支持多种BP配置参数时，在具体实现时，可选的，一个BP对应一个配置参数，其中配置参数包括子载波间隔或时间单位的类型或循环前缀(Cyclic Prefix，CP)类型等。以子载波间隔为例，若终端设备支持子载波间隔15kHz和30kHz，则基站可以为终端设备分配一个子载波间隔为15KHz的BP，和一个子载波间隔为30KHz的BP，终端设备根据不同的场景和业务需求，切换到不同的BP上，通常情况下终端设备不能同时在两个或多个BP上传输数据。
需要说明的是，以子载波间隔为例，当BP与子载波间隔对应时，则该BP中可以用于传输对应子载波间隔的物理信道信息和/或物理信号信息。当BP配置参数中包括子载波间隔、时间单位的类型或者CP类型中的一个或多个时，与BP配置参数包括子载波间隔的实现方式类似，在此不再赘述。
应理解，在本申请实施例中，当BP对应配置参数时，至少一个子BP的各个子BP的大小可能是相同的，也可能是不同的，具体的以BP1对应的子载波间隔为30KHz举例进行说明，假设BP1中包子BP1、子BP2和子BP3，基站针对子BP1、子BP2、子BP3分别分配一种子BP大小，比如，子BP1中包括2个30KHz对应的PRB，子BP2中包括4个30KHz对应的PRB，子BP3中包括8个30KHz对应的PRB。可选的每个子BP的大小是可以由基站配置的，并通知终端设备，具体的基站可以向终端设备发送指示各个子BP的编号与对应的子BP大小，还可以预先在终端设备和基站中预先配置各个子BP编号与对应的子BP大小的关系等，本申请实施例中不做具体限定。
在本申请实施例中，为了满足不同的需求，可选的，一个子BP对应一个配置参数，其中子BP对应的配置参数包括子载波间隔、时间单位的类型、或者CP类型等。以子载波间隔为例，若终端设备1支持子载波间隔60KHz、15KHz和30KHz，当各个子BP的大小相同时，则为终端设备1分配的BP1可以如图7a所示，BP1包括子BP1、子BP2和子BP3，其中子BP1、子BP2和子BP3的大小相同，但是子BP1对应的子载波间隔为60KHz，子BP2对应的子载波间隔为30KHz，子BP3对应的子载波间隔为15KHz；当各个子BP的大小不同时，则为终端设备1分配的BP1可以如图7b所示，其中BP1包括子BP1、子BP2和子BP3，其中子BP1的大小为a MHz，子BP2的大小为b MHz，子BP3的大小为c MHz，a、b和c均为大于0的有理数，且a、b和c不相等，而子BP1对应的子载波间隔为60KHz，子BP2对应的子载波间隔为30KHz，子BP3对应的子载波间隔为15KHz。
此外，在本申请实施例中一个子BP对应一个配置参数时，至少一个子BP中各个子 BP的大小可能相同，也可能是不相同的，具体的在至少一个子BP中各个子BP的大小不同时以图7b所示的BP1为例，基站针对子载波间隔为60KHz、15KHz和30KHz分别配置一种子BP大小，比如60KHz对应的子BP大小为2个60KHz对应的PRB，15KHz对应的子BP大小为8个15kHz对应的PRB，30kHz对应的子BP大小为4个30KHz对应的PRB，其中每个子载波间隔对应的子BP大小可以是预定义的，比如15KHz、30KHz、60KHz对应的子BP大小预定义为b KHz，b为大于0的整数，或15KHz、30KHz、60kHz对应的子BP大小都包含a个PRB，a为大于0的整数，或15kHz对应的子BP包含c个PRB，30KHz对应的子BP包含d个PRB，60KHz对应的子BP包含e个PRB，c，d，e为大于0的整数；可选的每个子BP的大小是可以由基站配置的，并通知终端设备，比如基站配置15KHz对应的子BP包含f个PRB，30KHz对应的子BP包含g个PRB。基站在给用户分配BP时，可以包含不同子载波间隔对应的子BP大小，比如一个BP中包含5个子载波间隔为15KHz对应的子BP，5个子载波间隔为30KHz对应的子BP，3个子载波间隔为60KHz对应的子BP，具体的，基站和终端设备之间可以在使用子载波间隔为15KHz对应的子BP所分配的带宽部分上传输子载波间隔为15KHz的物理信道信号和/或物理信号信息，在使用子载波间隔为30KHz对应的子BP所分配的带宽部分上传输子载波间隔为30KHz的物理信道信号和/或物理信号信息，在使用子载波间隔为60KHz对应的子BP所分配的带宽部分上传输子载波间隔为60KHz的物理信道信号和/或物理信号信息。
可选的，基站为终端分配一个BP后，该BP内不同频段对应不同的配置参数，配置参数包括子载波间隔、时间单位的类型、或者CP类型等。以子载波间隔为例，一个BP内对应二种子载波间隔，15KHz和30KHz，基站可以通过信令通知终端所述BP包括子载波间隔为15KHz对应的带宽部分和子载波间隔为30KHz对应的带宽部分。在具体实现时，基站和终端之间传输物理信道信息和/或物理信号信息所占用的资源，可以由基站预先通知给终端设备，例如，当BP大小为30MHz，包括使用子载波间隔为30KHz对应的子BP所分配的带宽部分10MHz和使用子载波间隔为60KHz对应的子BP所分配的带宽部分20MHz，则基站向终端设备发送信令通知终端BP包括的用于传输各个子载波间隔的物理信道信息和/或物理信号信息对应的带宽部分，终端设备根据基站的通知在不同的带宽部分上传输相应子载波间隔的物理信道信息和/或物理信号信息，比如基站发送信令通知终端设备BP中用于传输15KHz的物理信道信息和/或物理信号信息10MHz，用于传输30KHz的物理信道信息和/或物理信号信息20MHz。或者，基站和终端设备之间预先约定好在哪些带宽部分上传输哪些数据，例如，预先约定好在使用子载波间隔为15KHz对应的子BP分配的带宽部分上传输子载波间隔为15KHz的物理信道信息和/或物理信号信息，在使用子载波间隔为30KHz对应的子BP分配的带宽部分上传输子载波间隔为30KHz的数据，则基站和终端设备之间按照预先的约定在分配的BP上传输物理信道信息和/或物理信号信息。
