Description

一种数据传输方法、装置及设备 技术领域
本公开涉及无线通信技术领域，尤其涉及一种数据传输方法、装置及设备。
背景技术
随着无线通信技术的不断发展，在长期演进(long term evolution，LTE)技术之后出现了新无线(new radio，NR)技术。
在NR系统中，终端设备的服务小区通常是单载波小区，即一个服务小区只支持单个载波。但是面对未来网络中对业务量需求、终端数目以及终端种类都将会呈现爆发时的增长趋势，单载波服务小区的容量将无法满足需求。
所以，如何提高服务小区的容量是一个亟待解决的问题。
发明内容
本公开提供了一种数据传输方法、装置及设备，以实现在NR系统中配置多载波服务小区，进而提升服务小区的容量。
第一方面，本公开提供一种数据传输方法，该方法可以应用于一通信系统中的终端设备。该通信系统可以为NR系统。该方法可以包括：终端设备确定服务小区的非锚点载波在频带中的位置，其中，服务小区配置有锚点载波和非锚点载波；终端设备在非锚点载波上进行数据传输。
第二方面，本公开提供一种数据传输方法，该方法可以应用于一通信系统中的网络设备。该通信系统可以为NR系统。该方法可以包括：网络设备指示终端设备的服务小区的非锚点载波在频带中的位置，其中，服务小区配置有锚点载波和非锚点载波；网络设备在非锚点载波上进行数据传输。
第三方面，本公开提供一种通信装置，该通信装置可以为通信系统中的终端设备或者终端设备中的芯片或者片上系统，还可以为终端设备中用于实现上述各个实施例所述的方法的功能模块。该通信装置可以实现上述各实施例中终端设备所执行的功能，这些功能可以通过硬件执行相应的软件实现。这些硬件或软件包括一个或多个上述功能相应的模块。该通信装置包括：确定模块，用于确定服务小区的非锚点载波在频带中的位置，其中，服务小区配置有锚点载波和非锚点载波；第一传输模块，用于在非锚点载波上进行数据传输。
第四方面，本公开提供一种通信装置，该通信装置可以为通信系统中的网络设备或者网络设备中的芯片或者片上系统，还可以为网络设备中用于实现上述各个实施例所述的方法的功能模块。该通信装置可以实现上述各实施例中网络设备所执行的功能，这些功能可以通过硬件执行相应的软件实现。这些硬件或软件包括一个或多个上述功能相应的模块。该通信装置包括：指示模块，用于指示终端设备的服务小区的非锚点载波在频带中的位置，其中，服务小区配置有锚点载波和非锚点载波；第二传输模块，用 于在非锚点载波上进行数据传输。
第五方面，本公开提供一种通信设备，包括：天线；存储器；处理器，分别与天线及存储器连接，被配置为通执行存储在存储器上的计算机可执行指令，控制天线的收发，并能够实现如第一方面、第二方面及其可能的实施方式中任一项的数据传输方法。
第六方面，本公开提供一种计算机存储介质，处理模块，用于计算机存储介质存储有计算机可执行指令，其特征在于，计算机可执行指令被处理器执行后能够实现如第一方面、第二方面及其可能的实施方式中任一项的数据传输方法。
在本公开中，网络设备为终端设备的服务小区配置多个载波，提高了服务小区的容量。进一步地，若锚点载波为FR1载波，非锚点载波为FR2载波，则终端设备可以在处于idle态时驻留在FR1载波，而在业务到达时，向FR2载波发起随机接入，回到FR2载波进行数据传输。如此，降低功耗，节约资源。
应当理解的是，本公开的第三至六方面与本公开的第一至二方面的技术方案一致，各方面及对应的可行实施方式所取得的有益效果相似，不再赘述。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开实施例的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下 文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语“第一”、“第二”、“第三”等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，“第一信息”也可以被称为“第二信息”，类似地，“第二信息”也可以被称为“第一信息”。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
本公开实施例提供一种通信系统。该通信系统可以为第五代(5 th generation，5G)通信系统，如NR系统。图1为本公开实施例中的一种通信系统的结构示意图，参见图1所示，该通信系统100可以包括：终端设备101和网络设备102。
在一些可能的实施例中，上述通信系统100可以支持以非独立组网(non-standalone，NSA)和/或独立组网(standalone，SA)两种组网方式工作。那么，上述终端设备101可以支持NSA和/或SA，网络设备102可以支持NSA和/或SA。
示例性的，上述终端设备101可以为一种向用户提供语音或者数据连接性的设备。在一些实施例中，终端设备也可以称为用户设备(user equipment，UE)、移动台(mobile station)、用户单元(subsriber unit)、站台(station)或者终端(terminal equipment，TE)等。终端设备可以为蜂窝电话(cellular phone)、个人数字助理(personal digital assistant，PDA)、无线调制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)、无线本地环路(wireless local loop，WLL)台或者平板电脑(pad)等。随着无线通信技术的发展，可以接入无线通信系统、可以与无线通信系统的网络侧进行通信或者通过无线通信系统与其他设备进行通信的设备都是本公开实施例中的终端设备。例如，智能交通中的终端和汽车、智能家居中的家用设备、智能电网中的电力抄表仪器、电压监测仪器、环境监测仪器、智能完全网络中的视频监控仪器、收款机等。在本公开实施例中，终端设备可以与网络设备进行通信，多个终端设备之间也可以进行通信。终端设备可以是静态固定的，也可以移动的。
上述网络设备102可以为接入网侧用于支持终端接入无线通信系统的设备。例如，可以是4G接入技术通信系统中的演进型基站(evolved NodeB，eNB)、5G接入技术通信系统中的下一代基站(next generation NodeB，gNB)、发送接收点(transmission reception point，TRP)、中继节点(relay node)、接入点(access point，AP)等。
在上述通信系统中，终端设备的服务小区通常是单载波小区，即一个服务小区只支持单个载波。但是面对未来网络中对业务量需求、终端数目以及终端种类都将会呈现爆发时的增长趋势，单载波服务小区的容量将无法满足业务需求。所以，如何提高服务小区的容量是一个亟待解决的问题。
进一步地，上述通信系统所支持的频率范围分别定义为频率范围FR1(frequency range 1)和频率范围FR2(frequency range 2)。其中，频率范围FR1即为通常所讲的5G Sub-6GHz频段(450MHz至6000MHz)，频率范围FR2即为5G毫米波频段(24250MHz至52600MHz)。对于服务小区为FR2小区的终端设备来说，在空闲态(idle态)下，终端设备仍需要驻留在FR2小区。这样，增加了网络设备的功耗。
为了解决上述问题，本公开实施例提供一种数据传输方法，该方法可以应用于上述通信系统。
结合上述通信系统，以下行数据传输为例，图2为本公开实施例中的第一种数据传输方法的实施流程示意图，参见图2所示，上述数据传输方法可以包括：
S201，网络设备向终端设备指示非锚点载波在频带上的位置。
应理解的，网络设备可以为终端设备的服务小区配置多个载波，多个载波对应的小区标识(如物理小区标识(physical cell ID，PCI))是相同的。在一个小区的多个载波中，一个载波为锚点载波(anchor carrier)(也可以称为主载波)，其他载波为非锚点载波(non-anchor carrier)(也可以称为辅载波)。可选的，该服务小区也可以称为多载波服务小区(serving cell with multiple carriers)。
在一些可能的实施方式中，网络设备还可以根据终端设备的能力信息，为终端设备的服务小区配置多个载波。示例性的，终端设备通过能力信息(如UE-NR capability)向网络设备上报自身能够支持的最大载波数N，网络设备可以为终端设备的服务小区配置N个载波。
进一步地，锚点载波和非锚点载波可以为下行载波，或者锚点载波和非锚点载波可以为上行载波。
在一实施例中，网络设备可以选择一个载波部署锚点载波，并在锚点载波上发送主同步信号(primary synchronization signals，PSS)、辅同步信号(secondary synchronization signals，SSS)、物理广播信道(physical broadcast channel，PBCH)等。可选的，PSS、SSS和PRBCH组成同步信号和PBCH块(synchronization signal and PBCH block，SSB)。
进一步地，网络设备选择至少一个载波部署非锚点载波，此时，网络设备在非锚点载波上也可以发送PSS、SSS、PBCH等。当然，在非锚点载波上也可以不发送PSS、SSS、PBCH等。本公开实施例对此不作具体限定。
在一实施例中，网络设备在锚点载波上还可以发送物理下行共享信道(physical downlink share channel，PDSCH)、物理下行控制信道(physical downlink control channel，PDCCH)、物理随机接入信道(physical random access channel，PRACH)等，而在非锚点载波上可以发送PRACH，但不发送PDSCH、PDCCH等，本公开实施例对此不作具体限定。
示例性的，图3为本公开实施例中的锚点载波和非锚点载波的示意图，参见图3所示，网络设备为小区A配置3个载波。其中，载波1为部署的锚点载波，载波2为部署的一个非锚点载波，载波3为部署的另一个非锚点载波。载波1上可以传输SSB1、系统信息(system information，SI)、寻呼消息(paging)以及PRACH等。载波2可以传输PRACH，载波3可以传输PRACH。可选的，载波2还可以传输用于同步的SSB2，载波3还可以传输SSB3。
需要说明的是，上述锚点载波和非锚点载波可以为NR载波。可选的，锚点载波和非锚点载波可以为带内(intra-band)载波或者带间(inter-band)载波。
在一实施例中，为了降低功耗，锚点载波的中心频率可以低于非锚点载波的中心频率，即非锚点载波的中心频率F DL1满足：F DL1＞F DL2，其中，F DL2为锚点载波的中心频率。示例性的，锚点载波可以为FR1载波，非锚点载波可以为FR2载波，那么，当终端设备处idle态时，可以驻留在FR1载波(即锚点载波)上进行监听。当业务达到时，终端设备向FR2载波(即非锚点载波)发起随机接入，回到FR2载波进行数据传输。
在本公开实施例中，通过上述S201，网络设备可以通过在锚点载波上发送指示信息或者发送无线资源控制(RRC)信令来向终端设备指示非锚点载波在频带上的位置(或者非锚点载波的中心频率、载波带宽等锚点载波的配置信息。)
在一些可能的实施例中，网络设备除了指示非锚点载波在频带中的位置之外，还可以指示锚点载波和/或非锚点载波的下行配置信息、上行配置信息、参考信号配置信息等。
S202，终端设备确定非锚点载波在频带上的位置。
应理解的，终端设备可以根据S201中网络设备的指示，确定在频带上非锚点载波的位置。
S203，终端设备与网络设备在非锚点载波上进行数据传输。
应理解的，终端设备在通过S202确定出非锚点载波在频带上的位置之后，可以与网络设备在非锚点载波上进行数据传输。例如，终端设备在非锚点载波上接收网络设备发送的数据、终端设备在非锚点载波上向网络设备发送数据、网络设备在非锚点载波上向终端设备发送数据和/或网络设备在非锚点载波上接收终端设备发送的数据。
在本公开实施例中，对于频分双工(frequency division duplex，FDD)NR系统，由于上行载波和下行载波可以为不同频率的载波，那么，通过S202终端设备确定出的是下行非锚点载波，在S203中网络设备可以在下行锚点载波上发送下行数据，此时，下行数据可以包括随机接入信息、下行用户数据等；而对于时分双工(time division duplex，TDD)NR系统，由于上行载波和下行载波为同一载波，那么，在S203中终端设备可以在S202中确定出的非锚点载波上发送上行数据，如发送随机接入信息，网络设备可以分时在S202中终端设备确定出的非锚点载波上发送下行数据，如寻呼消息、下行用户数据等。
在一些可能的实施方式中，图4为本公开实施例中的第二种数据传输方法的实施流程示意图，参见图4所示，为了减少系统中信令交互，进一步地降低功耗，在S203之前，上述数据传输方法还可以包括：
S401，网络设备向终端设备在锚点载波上指示定时信息。
其中，上述定时信息用于指示非锚点载波与锚点载波的定时映射关系。示例性的，定时信息可以包括系统帧号偏移(system frame number offset，SFN offset)、帧边界偏移(frame boundary offset)以及时隙边界偏移(slot boundary offset)。当然。定时信息还可以包括用于指示非锚点载波与锚点载波之间的定时映射关系的其他信息，本公开实施例对此不作具体限定。
在实际应用中，网络设备可以将定时信息承载于SI，还可以将定时信息承载于RRC信令。
在一实施例中，若非锚点载波上不携带SSB，则网络设备可以通过S401向终端设备指示定时信息，以使得根据定时信息能够完成锚点载波和非锚点载波之间的同步。
进一步地，上述S203可以包括：S402，终端设备与网络设备在非锚点载波上根据定时信息进行数据传输。
在另一种可能的实施方式中，为了监控配置给服务小区的多个载波，实现移动性管理，在S202之后，终端设备还可以在非锚点载波上进行无线资源管理(radio resource management，RRM)测量、无线链路监测(radio link monitoring，RLS)测量、波束管理(beam management)测量等。
在本公开实施例中，网络设备为终端设备的服务小区配置多个载波，提高了服务小区的容量。进一步地，若锚点载波为FR1载波，非锚点载波为FR2载波，则终端设备可以在处于idle态时驻留在FR1载波，而在业务到达时，向FR2载波发起随机接入，回到FR2载波进行数据传输。如此，降低功耗，节约资源。

在一些可能的实施方式中，网络设备可以在锚点载波上向终端设备发送指示信息，以指示非锚点载波上的位置(也可以理解为指示非锚点载波的中心频、载波带宽等非锚点载波的配置信息)。
在一实施例中，在锚点载波上的PBCH中携带有主信息块(master information block，MIB)，可以将上述指示信息承载于MIB中指示非锚点载波上的位置。
在另一实施例中，在锚点载波上的PDSCH和/或PDCCH中携带有系统消息(system information，SI)，可以将上述指示信息承载于SI中指示非锚点载波上的位置。
在本公开实施例中，上述指示信息可以包括：SSB配置信息(如ssb-PositionsInBurst、ssb-PeriodicityServingCell、ss-PBCH-BlockPower等)、上下行配置信息(如tdd-UL-DL-ConfigurationCommon)、定时提前量(如n-TimingAdvanceOffset)、下行配置信息(如downlinkConfigCommon)、上行配置信息(如uplinkConfigCommon)等。
当然，上述指示信息还可以携带在锚点载波上的其他信息中，或者单独承载于锚点载波上，本公开实施例对此不作具体限定。
S502，终端设备根据指示信息，确定非锚点载波在频带上的位置。
应理解的，终端设备在锚点载波上接收网络设备发送的指示信息，并根据指示信息确定非锚点载波在频带上的位置。可选的，终端设备处于idle态。
在一实施例中，上述指示信息承载于SI中指示非锚点载波上的位置。S502可以为：终端设备可以先盲搜PSS和SSS，在搜到后，终端设备可以在锚点载波上接收MIB。接下来，终端设备根据MIB中指示，确定锚点载波上接收SI。然后，终端设备根据SI的指示，确定非锚点载波在频带上的位置。
在另一实施例中，上述指示信息承载于SI中指示非锚点载波上的位置。S502可以包括：终端设备可以先盲搜PSS和SSS，在搜到后，终端设备可以在锚点载波上接收MIB。接下来，终端设备根据MIB中指示，确定非锚点载波在频带上的位置。
S503，终端设备与网络设备在非锚点载波上进行数据传输。
应理解的，终端设备在通过S502确定出非锚点载波在频带上的位置之后，可以与网络设备在非锚点载波上进行数据传输。例如，终端设备在非锚点载波上接收网络设备发送的数据、终端设备在非锚点载波上向网络设备发送数据、网络设备在非锚点载波上向终端设备发送数据和/或网络设备在非锚点载波上接收终端设备发送的数据。
在本公开实施例中，对于FDD NR系统，由于上行载波和下行载波可以为不同频率的载波，那么，通过S502终端设备确定出的是下行非锚点载波，在S503中网络设备可以在下行锚点载波上发送下行 数据，此时，下行数据可以包括随机接入信息、下行用户数据等；而对于TDD NR系统，由于上行载波和下行载波为同一载波，那么，在S203中终端设备可以在S202中确定出的非锚点载波上发送上行数据，如发送随机接入信息，网络设备可以分时在S202中终端设备确定出的非锚点载波上发送下行数据，如寻呼消息、下行用户数据等。
在一些可能的实施方式中，上述SI还可以携带有定时信息，该定时信息用于指示非锚点载波与锚点载波的定时映射关系。示例性的，定时信息可以包括SFN offset、frame boundary offset以及slot boundary offset。当然。定时信息还可以包括用于指示非锚点载波与锚点载波之间的定时映射关系的其他信息，本公开实施例对此不作具体限定。
那么，仍参见图4所示，在S503之前，上述数据传输方法还包括：S401，网络设备向终端设备在锚点载波上指示定时信息。
在一实施例中，若非锚点载波上不携带SSB，则网络设备可以通过S401向终端设备指示定时信息，以使得根据定时信息能够完成锚点载波和非锚点载波之间的同步。
进一步地，上述S503可以包括：S402，终端设备与网络设备在非锚点载波上根据定时信息进行数据传输。
在另一种可能的实施方式中，为了监控配置给服务小区的多个载波，实现移动性管理，在S502之后，终端设备还可以在非锚点载波上进行RRM测量、RLS测量、波束管理测量等。
在本公开实施例中，网络设备为终端设备的服务小区配置多个载波，提高了服务小区的容量。进一步地，若锚点载波为FR1载波，非锚点载波为FR2载波，则终端设备可以在处于idle态时驻留在FR1载波，而在业务到达时，向FR2载波发起随机接入，回到FR2载波进行数据传输。如此，降低功耗，节约资源。进一步地，网络设备在锚点载波上向终端设备指示非锚点载波，使得终端设备可以通过监听锚点载波确定非锚点载波在频带上的位置，减少系统信令交互，降低功耗。

在本公开实施例中，对于FDD NR系统，由于上行载波和下行载波可以为不同频率的载波，那么，通过S502终端设备确定出的是下行非锚点载波，在S503中网络设备可以在下行锚点载波上发送下行数据，此时，下行数据可以包括随机接入信息、下行用户数据等；而对于TDD NR系统，由于上行载波和下行载波为同一载波，那么，在S203中终端设备可以在S202中确定出的非锚点载波上发送上行数据，如发送随机接入信息，网络设备可以分时在S202中终端设备确定出的非锚点载波上发送下行数据，如寻呼消息、下行用户数据等。
