资源分配的方法、用户设备和网络设备
本申请要求于2017年5月5日提交中国专利局、申请号为201710314022.9、申请名称为“资源分配的方法、用户设备和网络设备”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
本申请涉及通信领域，并且更具体地，涉及资源分配的方法、用户设备和网络设备。
背景技术
在长期演进(Long Term Evolution，LTE)中，用户设备(User Equipment，UE)所使用的带宽部分的频域资源分配需要依赖于系统带宽的带宽大小。然而，在第五代移动通信(the 5th Generation，5G)新空口(New Radio，NR)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UE带宽部分的频域资源位置的方法。
发明内容
本申请提供一种资源分配的方法、用户设备和网络设备，能够不依赖于系统带宽大小确定带宽部分的频域资源位置。
第一方面，提供了一种资源分配的方法，该方法包括：确定第一频域资源的第一位置；根据该第一位置与至少一个带宽部分的第二位置之间的偏移，以及该第一位置，确定该第二位置；根据该至少一个带宽部分的第二位置和该至少一个带宽部分的带宽大小，确定该至少一个带宽部分；在第一带宽部分上传输物理信号信息和物理信道信息中的至少一项，该第一带宽部分为该至少一个带宽部分中的一个或多个带宽部分。
UE确定第一频域资源的第一位置，根据该第一位置与至少一个带宽部分中每个带宽部分的第二位置之间的偏移，以及该第一位置确定该第二位置，并根据该至少一个带宽部分的第二位置和该至少一个带宽部分的带宽大小确定该至少一个带宽部分的频域资源，在该至少一个带宽部分中的第一带宽部分上传输物理信号信息和物理信道信息中的至少一项，这样UE能够避免依赖系统带宽的大小确定带宽部分的频域资源位置。
在一些可能的实现方式中，该第一位置与至少一个带宽部分的第二位置之间的偏移可以是第一位置与该至少一个带宽部分的第二位置之间的偏移值和偏移方向。
在一些可能的实现方式中，该第一位置为该第一频域资源的起始位置、中心位置或结束位置，该第二位置为该带宽部分的起始位置、中心位置或结束位置。
UE以第一频域资源的起始位置、中心位置或结束位置作为参考点，可以确定带宽部分的起始位置、中心位置或结束位置，这样UE避免了依赖系统带宽的大小确定带宽部分的频域资源位置。
在一些可能的实现方式中，该偏移值的粒度为资源块RB、资源块组PBG或子带宽中的任一项。
若带宽部分为第一公共带宽部分则该偏移值的粒度可以是RB或PBG，若带宽部分为第二公共带宽部分则该偏移值的粒度可以是RB、PBG或子带宽。第一公共带宽部分为用于初始接入的公共带宽部分，第二公共带宽部分为除用于初始接入的公共带宽部分的其他公共带宽部分。UE根据第一频域资源的第一位置和偏移值的粒度能够准确的确定出带宽部分的第二位置，提高了确定频域资源的准确度。
在一些可能的实现方式中，该在该至少一个带宽部分中的第一带宽部分上传输理信号信息和物理信道信息中的至少一项之前，该方法还包括：接收第一指示信息，该第一指示信息用于指示该至少一个带宽部分中的第一带宽部分；根据该第一指示信息，确定该带宽部分。
在带宽部分的第二位置与第一频域资源的第一位置的偏移为UE和网络设备预先设定的情况下，UE可以接收网络设备在确定第一频域资源后发送的第一指示信息，根据该第一指示确定该至少一个带宽部分中的第一带宽部分，这样网络设备不需要为每个带宽部分的第二位置配置与第一频域资源的第一位置的偏移，节省了网络设备的功耗。
在一些可能的实现方式中，在确定该第二位置之前，该方法还包括：接收第二指示信息，该第二指示信息用于指示该第一位置与该第二位置的偏移。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种基于非正交多址接入技术的通信系统，例如稀疏码多址接入(Sparse Code Multiple Access，SCMA)系统、低密度签名(Low Density Signature，LDS)系统等，当然SCMA系统和LDS系统在通信领域也可以被称为其他名称；进一步地，本申请实施例的技术方案可以应用于采用非正交多址接入技术的多载波传 输系统，例如采用非正交多址接入技术正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)、滤波器组多载波(Filter Bank Multi-Carrier，FBMC)、通用频分复用(Generalized Frequency Division Multiplexing，GFDM)、滤波正交频分复用(Filtered-OFDM，F-OFDM)系统等。
本申请实施例中的用户设备可以指接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的用户设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的用户设备等，本申请实施例并不限定。
本申请实施例中的网络设备可以是用于与用户设备通信的设备，该网络设备可以是全球移动通讯(Global System of Mobile communication，GSM)系统或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional NodeB，eNB或eNodeB)，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网络中的网络设备等，本申请实施例并不限定。
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用户设备10和网络设备20。网络设备20用于为用户设备10提供通信服务并接入核心网，用户设备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用户设备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UE接入网络设备的示意性流程图。如图2所示，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(Primary Synchronization Signal，PSS)和辅同步信号(Secondary Synchronization Signal，SSS)。
202，UE进行小区搜索，并根据PSS或SSS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PSS/SSS与第一小区保持在时间和频率上的同步。
203，UE获取第一小区发送的主信息块(Master Information Block，MIB)和系统信息块(System Information Block，SIB)。其中，MIB的时频域资源为预定义的，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(Physical Random Access Channel，PRACH)向网络设备发送前导码，其中，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(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(Physical Downlink Shared Control Channel，PDSCH)中反馈MAC的随机接入响应(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(Message 3，Msg3)。其中，Msg3可能携带无线资源控制(Radio Resource Control，RRC)建链消息(RRC Connection Request)，也可能携带RRC重建消息(RRC Connection Re-establishment Request)。
208，网络设备向UE发送消息4(Message 4，Msg4)。网络设备和UE最终通过Msg4完成竞争解决。
在LTE中，UE使用的带宽部分的资源分配需要依赖于系统带宽的大小。然而，在5G NR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是本申请实施例的资源分配的方法的示意性流程图。
301，用户设备确定第一频域资源的第一位置。
可选地，该第一位置可以是第一频域资源的起始位置、中心位置或结束位置。该第一位置还可以是第一频域资源的任何一个位置，本申请对此不进行限定。
应理解，第一频域资源的起始位置可以是第一频域资源的最小资源块(Resource Block，RB)或最小资源块组(Resource Block Group，RBG)，相应地结束位置为第一频域资源的最大RB或最大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最大RB或RBG，相应地结束位置为第一频域资源的最小RB或最小RBG。为描述方便，下述实施例中以起始位置为最小RB或最小RBG为例进行说明。
可选地，该第一频域资源可以是同步信号块的频域资源。同步信号块包括PSS和SSS，还可以包括主信息块。
302，用户设备根据该第一位置，以及该第一位置与至少一个带宽部分的第二位置之间的偏移，确定该第二位置。
用户设备可以与网络设备预先设定第一频域资源的第一位置与至少一个带宽部分中的每个带宽部分的第二位置之间的偏移。这样，在用户设备能够确定第一频域资源的第一位置时，就可以根据与该第一位置的偏移确定出带宽部分的第二位置。
需要说明的是，本申请实施例的带宽部分的第一位置可以理解为带宽部分的频域资源的第一位置。
应理解，本申请实施例中的带宽部分也可以称为“工作带宽”。
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，该第二位置为带宽部分的结束位置或中心位置。本申请对此不进行限定。
需要说明的是，该至少一个带宽部分中的每个带宽部分的第二位置与第一频域资源的第一位置的偏移方向和偏移位置可以全部相同，也可以全部不同，或者部分相同。例如，该至少一个带宽部分中的第一带宽部分的第二位置与第一频域资源的第一位置向上偏移2个RB，而该至少一个带宽部分中的第二带宽部分的第二位置与第一频域资源的第一位置向下偏移5个RB。该向上偏移表示向频率增大的方向偏移，该向下偏移表示向频率减小的方向偏移。
可选地，用户设备可以接收网络设备发送的第二指示信息，该第二指示信息用于指示该第一频域资源的第一位置与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，用户设备根据该第二指示信息确定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二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。或者在UE不处于随机接入过程时，基站还可以通过无线资源控制信令携带该第二指示信息；或者在UE处于随机接入过程时，基站还可以通过随机接入响应信令携带该第二指示信息，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203获取的SIB，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MIB。无线资源控制信令可以是图2中步骤207的Msg3消息中携带的RRC信令，随机接入响应信令可以是图2中步骤206的RAR信令。
可选地，作为一个实施例，在第一频域资源为同步信号块的频域资源时，该带宽部分可以是公共带宽部分，UE可以在该公共带宽部分中接收公共物理信号信息、公共物理下行控制信道(Physical Downlink Control Channel，PDCCH)信息、公共物理下行共享信道(Physical Downlink Shared Channel，PDSCH)信息中的至少一项。该公共物理信号可以是主/辅同步信号、信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)等；该公共PDCCH信息可以是通过公共无线网络临时标识(Radio Network Temporary Identity，RNTI)加扰的下行控制信息，该公共RNTI可以是系统消息RNTI(System Information-RNTI，SI-RNTI)、寻呼RNTI(Paging-RNTI，P-RNTI)、随机接入RNTI(Random Access-RNTI，RA-RNTI)等；该公共PDSCH信息可以是系统信息、寻呼和随机接入响应等。也就是说，UE可以根据同步信号块的第一位置确定公共带宽部分的第二位置。例如，如图4所示，UE可以根据同步信号块的资源起始位置以及根据同步信号块的频域起始位置与第二公共带宽部分的起始位置的偏移值和偏移方向确定出第二公共带宽部分的起始位置。
需要说明的是，若该公共带宽部分为用于初始接入的公共带宽部分，即该公共带宽部分用于传输同步信号块，为便于描述，下述称为“第一公共带宽部分”，则偏置值的粒度可 以为RB或PBG，第二指示信息可以是通过主信息块携带。
若该公共带宽部分为除用于初始接入的公共带宽部分的其他公共带宽部分，即该公共带宽部分可以不用于传输同步信号块，为便于描述，下述称为“第二公共带宽部分”，则偏置值的粒度可以为RB、PBG或子带宽，第二指示信息可以是通过主信息块、系统信息块或无线资源控制信令携带。

应理解，对于一个用户设备，带宽部分不大于该用户设备支持的最大带宽，换言之，带宽部分不大于该用户设备的带宽能力。
需要说明的是，第一公共带宽部分的最小值不小于同步信号块传输带宽，最大值不大于最小UE带宽能力。该最小UE带宽能力为多个UE支持的最大带宽的最小值，是频段特定或者是系统参数集合特定的。例如，对于独立组网NR，6GHz以下频段(对应子载波间隔包括15KHz、30KHz、60KHz，同步信号块子载波间隔为30KHz，带宽不小于10MHz)最小UE带宽能力不小于10MHz，6GHz以上频段(对应子载波间隔包括120KHz和240KHz，同步信号块子载波间隔为120KHz，带宽不小于40MHz)最小UE带宽能力不小于40MHz；对于非独立组网NR，最小UE带宽能力不小于min(20MHz，同步信号块传输带宽)，其中20MHz为LTE的最小UE带宽能力。
