以下，对本申请中的部分用语进行解释说明，以方便本领域技术人员理解。
1)本申请所述的“网络设备”，也可以称之为无线接入网设备，可以是gNB(gNode B)，可以是普通的基站(例如WCDMA系统中的基站(NodeB，NB)，LTE系统中的演进型基站(Evolutional NodeB，eNB或eNodeB)，GSM或CDMA中的基站(Base Transceiver Station，BTS))，可以是新无线控制器(New Radio controller，NR controller)，可以是集中式网元(Centralized Unit)，可以是新无线基站，可以是射频拉远模块，可以是移动管理实体(mobile management entity，MME)，可以是微基站，可以是分布式网元(Distributed Unit)，可以是接收点(Transmission Reception Point，TRP)或传输点(Transmission Point，TP)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备或者任何其它无线接入设备，但本申请实施例不限于此。
2)本申请所述的“终端”，可以是无线终端也可以是有线终端。无线终端可以是指向用户提供语音和/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。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设备，如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机，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，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，SU)、订户站(Subscriber Station，SS)，移动站(Mobile Station，MB)、移动台(Mobile)、远程站(Remote Station，RS)、接入点(Access Point，AP)、远程终端(Remote Terminal，RT)、接入终端(Access Terminal，AT)、用户终端(User Terminal，UT)、用户代理(User Agent，UA)、终端设备(User Device，UD)、或用户装备(User Equipment，UE)。为方便描述，在本申请实施例中，终端设备和UE经常交替使用。
3)本申请所述的“载波带宽部分(英文：carrier bandwidth part)”，是指信道带宽中的一部分，也可以叫做“带宽部分(英文:bandwidth part)”，“工作带宽(英文：operating  bandwidth)”或者传输带宽，迷你BP(mini BP)、BP单元(BP Unit)、BP子带等，可以简称为BP，也可以简称为BWP，本申请实施例中不对载波带宽部分的名称以及简称进行具体限定。BP是指在数据传输时两级资源分配中第一步确定的带宽。可以为频域上一段连续或非连续的资源。例如，一个载波带宽部分包含连续或非连续的K>0个子载波；或者，一个载波带宽部分为N>0个不重叠的连续或非连续的资源块(Resource Block)所在的频域资源；或者，一个载波带宽部分为M>0个不重叠的连续或非连续的资源块组(Resource Block Group，RBG)所在的频域资源，一个RBG包括P>0个连续的RB。一个载波带宽部分与一个特定的参数numerology集合相关，所述参数集合包括子载波间隔和循环前缀(Cyclic Prefix，CP)的至少一种。
4)本申请所述的“参数(numerology)”，是指空口(英文：air interface)中的一系列物理层参数，具体实现时，可选的，一个BP可以对应一个numerology。numerology包括子载波间隔，时间单位的类型或循环前缀(英文：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，可以切换到不同的BP上，或者同时在两个或更多BP上传输数据。当终端设备支持多个BP时，每个BP对应的numerology可以相同也可以不同。
为方便描述，在本申请实施例中，“终端”，“用户设备”以及“UE”经常交替使用。
另外，本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
除非有相反的说明，本申请实施例提及“第一”、“第二”、“第三”、“第四”以及“第五”等序数词用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。
图1是本申请一个应用场景的示意图。图1中的通信系统可以包括终端10和网络设备20。网络设备20用于为终端10提供通信服务并接入核心网，终端10通过搜索网络设备20发送的同步信号、广播信号等而接入网络，从而进行与网络的通信。图1中所示出的箭头可以表示通过终端10与网络设备20之间的蜂窝链路进行的上/下行传输。
图2是终端接入网络设备的示意性流程图。如图2所示，终端(下文中为表述方便，简称为UE)接入网络设备的步骤主要包括：
201，网络设备周期地发送同步信号块，同步信号块包括主同步信号(英文：Primary Synchronization Signal，PSS)和辅同步信号(英文：Secondary Synchronization Signal，SSS)。
202，UE进行小区搜索，并根据同步信号块选择一个最好的小区进行驻留，为方便描述，将“最好的小区”表示为第一小区。此外，UE能够根据同步信号块中的PSS和/或SSS与第一小区保持在时间和频率上的同步。UE获取所述同步信息块的主信息块(英文：Master Information Block，MIB)，其中，MIB的时频域资源为预定义的。
203，UE获取第一小区发送的系统信息块(英文：System Information Block，SIB)。其中，SIB的时域资源是预定义的，SIB的频域资源是通过下行控制信道调度的。
204，UE获取了MIB和SIB后，发起随机接入过程与第一小区建立连接，当接入类型为基于竞争的接入时，接入过程包括步骤205、206、207、208；当接入类型为基于非竞争的接入时，接入过程包括步骤205和206。
205，UE在物理随机接入信道(英文：Physical Random Access Channel，PRACH)向网络设备发送随机接入前导码，其中，随机接入前导码的资源是通过SIB指示的。
206，网络设备在PRACH中盲检测前导码，如果网络设备检测到了随机接入前导码，则上报给媒体访问控制(英文：Media Access Control，MAC)，后续会在随机接入响应窗口内，在物理下行共享信道(英文：Physical Downlink Shared Control Channel，PDSCH)中反馈MAC的随机接入响应(英文：Radom Access Response，RAR)信令。
207，UE接收RAR信令，根据RAR信令中的TA调整量可以获得上行同步，并在网络设备为其分配的上行资源中传输消息3(英文：Message 3，Msg3)。其中，Msg3可能携带无线资源控制(英文：Radio Resource Control，RRC)建链消息(英文：RRC Connection Request)，也可能携带RRC重建消息(英文：RRC Connection Re-establishment Request)。
208，网络设备向UE发送消息4(英文：Message 4，Msg4)。网络设备和UE最终通过Msg4完成竞争解决。
在LTE中，UE使用的载波带宽部分的资源分配需要依赖于系统带宽的大小。然而，在下一代通信系统中，UE可能并不知道系统带宽的大小。因此，亟待设计一种不依赖于系统带宽大小确定工作带宽的频域资源的位置的方法。
图3是本申请一个实施例提供的一种资源分配的方法300的示意性流程图。该方法300可以应用于图1所示的场景中。方法300包括以下步骤。
S301、终端在第一频域资源上向网络设备发送随机接入前导。
具体地，所述第一频域资源为所述终端发送随机接入前导的物理随机接入信道的频域资源。
S302、终端根据第一频域资源对应的第一信息，确定第二频域资源。
终端可以根据第一频域资源对应的第一信息，确定第二频域资源的频域位置和/或带宽，所述第二频域资源可以是频域上一段连续或非连续的资源。所述第一频域资源和所述第二频域资源位于同一载波。其中，所述第一频域资源对应的第一信息包括以下中的至少一项：所述第一频域资源的索引；第一频域资源的频域位置信息；所述第一频域资源的带宽；所述第一频域资源对应的参数；所述第一频域资源对应的随机接入前导的索引；所述随机接入前导的子载波间隔；所述随机接入前导的带宽；所述随机接入前导的循环前缀时间长度以及所述随机接入前导的序列长度。
网络设备通过SIB指示一个或者多个PRACH资源以及各PRACH资源对应的随机接入前导(PRACH preamble)的格式。例如，网络设备指示3个PRACH资源，即PRACH资源#1、#2、#3，各PRACH资源对应的PRACH preamble格式如0所示。可以看出，一个PRACH资源可以对应一种PRACH preamble格式(如PRACH资源#2、#3)，也可以对应多种PRACH preamble格式(如PRACH资源#1)。

在本申请中，所述终端和所述网络设备分别通过发送和接收随机接入前导的PRACH资源，来确定所述第二频域资源，进而在该第二频域资源上发送或接收数据，这样可以使终端根据自身业务需求和/或所处网络环境，从多个第二频域资源中确定使用的一个，从而可以减少资源配置信令的开销。

下面，来举例说明如何根据所述第一映射方式来确定所述第二频域资源。
例如，当存在多个第二频域资源时，任意两个第二频域资源的索引，带宽，频域位置和/或对应的参数互不相同。即每个第二频域资源对应一个特定的索引，带宽，频域位置和/或参数。例如，存在2个第二频域资源时，编号分别为第二频域资源A以及第二频域资源B，其中第二频域资源A对应索引A，带宽A，频域位置A，参数A；第二频域资源B对应索引B，带宽B，频域位置B，参数B；索引A与索引B不同，带宽A与带宽B不同，频域位置A与频域位置B不同，参数A与参数B不同。因此，根据上述第一映射方式中的任意一种映射方式即可唯一确定第二频域资源。
例如，当存在多个第二频域资源时，任意两个第二频域资源所对应的索引，带宽，频域位置和对应的参数中至少一个不同。举例来说，第二频域资源A对应索引A，带宽A，频域位置A，参数A，所述第二频域资源B对应索引B，带宽A，频域位置B,参数A，因此，例如，可以根据第一频域资源的索引与第二频域资源的索引之间的映射确定第二频域资源A，从而确定第二频域资源A的带宽和频域位置，也可以根据第一频域资源的索引与第二频域资源的频域位置之间映射确定第二频域资源从而确定第二频域资B和带宽和频域位置。
本领域技术人员可以理解的是，上文中仅是对于如何根据第一映射方式来确定所述第二频域资源进行举例说明，本领域技术人员在通读本申请的基础上，可以得知如何根据所述第一映射方式的各种不同的方式的组合来确定所述第二频域资源，这些属于本申请应有之意，本申请对于如何根据第一映射方式中所包括的其它方式来确定所述第二频域资源，不再一一赘述。
可选的，所述第一映射方式可以是预先设置的。这样，终端在确定第一频域资源后，就可以根据预先设定的所述第一映射方式来确定所述第二频域资源。
可选的，该终端可以接收网络设备发送的第一指示信息，该第一指示信息用于指示所述映射方式。这样，网络设备可以灵活地指示所述映射方式，提高了资源分配的灵活性。
可选的，该第一指示信息携带在系统消息块中。
可选的，所述终端可以接收所述网络设备发送的第二指示信息，该第二指示信息承载系统消息块中，用于指示多个候选第二频域资源，所述多个候选第二频域资源中包括所述第二频域资源。
可选的，所述终端根据所述第二指示信息，可以确定以下至少一项：所述至少一个候选第二频域资源的索引；所述至少一个候选第二频域资源对应的参数；所述至少一个候选第二频域资源的频域位置；以及所述至少一个候选第二频域资源的带宽。可以理解的是，所述至少一个候选第二频域资源的索引，指的是所述至少一个候选第二频域资源中所包括 的每个候选第二频域资源的索引。所述至少一个候选第二频域资源对应的参数，指的是所述至少一个候选第二频域资源中所包括的每个候选第二频域资源对应的参数。所述至少一个候选第二频域资源的频域位置，指的是所述至少一个候选第二频域资源中所包括的每个候选第二频域资源的频域位置。所述至少一个候选第二频域资源的带宽，指的是所述至少一个候选第二频域资源中所包括的每个候选第二频域资源的带宽。
可选的，该第一频域资源的频域位置信息可以是该第一频域资源的起始位置、中心位置或结束位置。当然，该第一频域资源的频域位置信息可以是第一频域资源的任何一个位置，本申请对此不作限定。所述终端可以根据所述第一频域资源的第一位置，以及所述第一位置与所述第二频域资源的第二位置之间的偏移，确定所述第二位置，并根据所述第二位置和所述第二频域资源的带宽，确定所述第二频域资源。所述网络设备可以根据所述第一频域资源的第一位置，以及所述第一位置与所述第二频域资源的第二位置之间的偏移，确定所述第二位置，并根据所述第二位置和所述第二频域资源的带宽，确定所述第二频域资源。
应理解，第一频域资源的起始位置可以是第一频域资源中索引最小的资源块(英文：Resource Block，RB)或索引最小资源块组(英文：Resource Block Group，RBG)，相应地结束位置为第一频域资源的索引最大的RB或索引最大的RBG。或者该第一频域资源的起始位置也可以是第一频域资源的索引最大的RB或索引最大的RBG，相应地结束位置为第一频域资源的索引最小的RB或索引最小的RBG。为描述方便，下述实施例中以起始位置为索引最小的RB或索引最小的RBG为例进行说明。
终端可以与网络设备预先设定第一频域资源的第一位置与所述第二位置之间的偏移。这样，在终端能够确定所述第一位置时，就可以根据与该第一位置的偏移确定所述第二频域资源的第二位置。
可选地，该第一位置与第二位置之间的偏移可以是该第一位置与第二位置的偏移值和偏移方向。
可选地，偏移值的粒度可以为RB、PBG、子载波或子带宽等。
具体地，该偏移值的粒度可以是计算第一位置和第二位置之间的偏移值时使用的单位。例如，第一载波带宽部分的第二位置为第一频域资源的第一位置向上或向下移动2个RB，此时偏移值的粒度为RB。
可选地，该第二位置可以是与第一位置相对应的，例如，若第一位置为第一频域资源的起始位置，则该第二位置为载波带宽部分的起始位置；若第一位置为第一频域资源的中心位置，则该第二位置为载波带宽部分的中心位置；若第一位置为第一频域资源的结束位置，则该第二位置为载波带宽部分的结束位置。或者，该第二位置不与该第一位置相对应，例如，该第一位置为第一频域资源的起始位置，该第二位置为载波带宽部分的结束位置或中心位置。本申请对此不进行限定。
可选的，终端可以接收网络设备发送的第三指示信息，该第三指示信息用于指示该第一频域资源的第一位置与载波带宽部分的第二位置的偏移。这样网络设备可以灵活的指示第二位置相对于第一位置的偏移，用户设备根据该第三指示信息确定载波带宽部分的第二位置，提高了资源分配的灵活性。
可选地，用户设备接收网络设备发送的第三指示信息可以通过主信息块携带，或者通过系统信息块携带，本申请对此不进行限定。
需要说明的是，本申请实施例中的主信息块可以是LTE中的主信息块，例如，如图2中步骤202获取的MIB，本申请对主信息块的名称不进行限定。系统信息块也可以是LTE中的系统信息块，例如，图2步骤203获取的SIB。
需要说明的是，终端选择PRACH资源和/或PRACH preamble格式的方法包括但不限于：若网络中多个PRACH资源对应的PRACH preamble格式相同，则终端设备随机地选择一个PRACH资源发送PRACH preamble；若网络中多个PRACH资源对应的PRACH preamble格式不同，终端还可以根据自身的需求和/或所处网络环境选择PRACH preamble格式以及对应的PRACH资源。例如，对于高速移动的终端设备(对应较大的多普勒偏移)，其会选择子载波间隔较大的PRACH preamble格式，例如PRACH资源3对应的PRACH preamble格式；而对于处于小区边缘的终端设备(对应较大的下行路损)，其会选择重复次数更多的PRACH preamble格式，例如PRACH资源2对应的PRACH preamble格式。进而，终端设备根据所选PRACH资源确定上行载波带宽部分的频域资源。
可选的，作为一个具体的实施例，在S301中，所述终端根据所述第一频域资源，确定所述第二频域资源，具体包括：所述终端设备根据所述第一频域资源对应的所述第一信息与第三频域资源对应的第三信息之间的第二映射方式，以及所述第三频域资源对应的所述第三信息与所述第二频域资源对应的所述第二信息之间的第三映射方式，来确定所述第二频域资源。在S303中，所述网络设备根据所述第一频域资源，确定所述第二频域资源，具体包括：所述网络设备根据所述第一频域资源对应的第一信息与第三频域资源对应的第三信息之间的第二映射方式，以及所述第三频域资源对应的所述第三信息与所述第二频域资源对应的所述第二信息之间的第三映射方式，来确定所述第二频域资源。可选的，所述第三频域资源为所述网络设备发送随机接入响应的频域资源或者所述网络设备调度所述随机接入响应的控制信道资源，所述第三频域资源对应的第三信息包括以下至少一项：所述第三频域资源的索引，所述第三频域资源对应的参数，所述第三频域资源对应的带宽以及所述第三频域资源对应的频域位置信息。
