本发明一实施例提供一种载波配置方法,如图1所示,该方法可以包括:
101、网络设备为UE配置载波聚合模型,以便UE根据载波聚合模型与网络设备进行数据传输。
其中,网络设备为UE配置的载波聚合模型包括多个成员载波,该多个成员载波中包括至少一个核心载波,至少一个核心载波中包括至少一个主核心载波,也就是说,载波聚合模型包括的多个成员载波中,可以包括一个核心载波,也可以包括至少两个核心载波,且,当多个成员载波包括一个核心载波时,该核心载波即为主核心载波,当多个成员载波中包括至少两个核心载波时,该至少两个核心载波中可以包括至少一个主核心载波。
本发明实施例中所述的核心载波具备上行传输功能和下行传输功能,该上行传输功能包括以下至少一种:下行数据对应的上行反馈功能、下行信道状态反馈功能、上行数据传输功能,该下行传输功能包括以下至少一种:上行数据对应的下行反馈功能、上行信道 状态反馈功能、下行数据传输功能。非核心载波,即载波聚合模型包括的多个成员载波中除核心载波之外的载波具有上行传输功能和/或下行传输功能。本发明实施例中所述的主核心载波具备以下功能中的至少一种:承载系统消息功能、承载寻呼消息功能、配置半静态调度参数功能、驻留参考功能,加密参考功能,具体的,驻留参考功能表示UE会驻留在主核心载波对应的小区中,并且在位置更新时以主核心载波对应的小区作为服务小区进行位置上报,加密参考功能表示网络设备和UE是根据主核心载波对应的服务小区的小区标识行加密的。
示例性的,网络设备为UE配置的载波聚合模型包括6个成员载波,分别是CC0、CC1、CC2、CC3、CC4、CC5,其中,CC0、CC1均为核心载波,分别具备上行传输功能和下行传输功能,CC1为主核心载波,其余的成员载波CC2、CC3、CC4、CC5均为非核心载波,分别具备上行传输功能和/或下行传输功能,这样在网络设备为UE配置了聚合载波模型之后,UE便可以驻留在CC1对应的小区中,并可以读取CC1对应的小区的系统广播、还可以从CC1对应的小区中收取寻呼消息等等,并可以基于CC0、CC1、CC2、CC3、CC4、CC5,采用载波聚合技术与网络设备之间进行数据传输。
本发明实施例提供的载波配置方法,网络设备为UE配置载波聚合模型,以便UE根据载波聚合模型与网络设备进行数据传输,该载波聚合模型中包括多个成员载波,多个成员载波包括至少一个核心载波,至少一个核心载波中包括至少一个主核心载波,通过为UE配置包括至少一个核心载波的载波聚合模型,可以区分出普通辅载波和重要辅载波,并将重要辅载波也作为核心载波,这样不仅有利于重要辅载波的载波管理,还增加了UE使用核心载波的可选择性。
进一步的,在执行步骤101之前,网络设备可以将多个成员载波中具备上行传输功能和下行传输功能的成员载波确定为所述核心载波。
其中,网络设备可以将多个成员载波包括的辅载波(辅载波指的是多个成员载波中除主载波之外的成员载波,该主载波也属于本发明实施例中所述的核心载波中的一个,该主载波是预先指定的)中具备上行传输功能和下行传输功能的成员载波直接确定为核心载波。
当然,网络设备还可以在确定出具备上行传输功能和下行传输功能的成员载波之后,进一步的,将具备上行传输功能和下行传输功能的成员载波中信道质量大于预设阈值的成员载波确定为核心载波,或者,将具备上行传输功能和下行传输功能的成员载波中信道质量相对较好的成员载波确定为核心载波。
进一步的,为了提高UE与网络设备通信的稳定性,当多个成员载波包括至少两个核心载波时,在第一种可能的实现方式中,网络设备可以主动触发主核心载波的变更,具体的,在步骤101之后,网络设备可以确定进行主核心载波变更,从辅核心载波中确定新的主核心载波,并向UE发送主核心载波变更通知消息,以便UE将主核心载波变更为新的主核心载波。
其中,网络设备确定进行主核心载波变更,具体的可以包括,网络设备根据UE的测量报告确定辅核心载波的信道质量好于当前的主核心载波的信道质量,则确定进行主核心载波变更,可以是将根据测量报告确定的信道质量好于当前的主核心载波的辅核心载波更新为主核心载波。或者,网络设备确定当前的主核心载波对应的小区的负载比较高,则确定进行主核心载波变更。
其中,辅核心载波为至少两个核心载波中除主核心载波外的其他的核心载波,主核心载波变更通知消息用于通知UE进行主核心载波变更。
示例性的,若多个成员载波中包括两个核心载波,网络设备从辅核心载波中确定新的主核心载波具体的可以是:网络设备将除当前的主核心载波外的辅核心载波直接作为新的主核心载波,并向UE发送的主核心载波变更通知消息,这样由于多个成员载波中仅包括 两个核心载波,那么UE在接收到网络设备发送的主核心载波变更通知消息之后,便可以将两个核心载波中除当前的主核心载波外的辅核心载波变更为新的主核心载波。若多个成员载波中包括三个或三个以上的核心载波,网络设备从辅核心载波中确定新的主核心载波具体的可以是:网络设备根据辅核心载波的信道质量或辅核心载波对应的小区的负载情况从辅核心载波中确定新的主核心载波,并向UE发送的携带新的主核心载波的标识的主核心载波变更通知消息,这样UE在接收到网络设备发送的主核心载波变更通知消息之后,便可以根据主核心载波变更通知消息中携带的标识,将标识对应的辅核心载波变更为新的主核心载波。
进一步的,网络设备向UE发送主核心载波变更通知消息具体的可以为:网络设备通过物理层信令或媒体访问控制(英文:Medium Access Control,简称:MAC)层信令向UE发送主核心载波变更通知消息。

示例性的,UE触发的RACH过程具体的是竞争RACH过程,其具体的可以包括,UE确定前导序列,并发送前导序列给网络设备,网络设备收到前导序列后给UE发送确认信息,所述确认信息用于指示后续UE传输使用的上行授权和/或调整UE的上行发送定时,UE根据所述上行授权发送携带UE标识信息的上行数据单元给网络设备,网络设备根据所述上行数据单元中携带的UE标识确认之前收到的前导序列的UE,并发送携带UE标识的授权或者下行数据单元给UE,以便UE确认网络设备收到了所述上行数据单元。其中,网络设备可以是根据接收到的UE发送的携带UE标识的上行数据单 元确定UE主核心载波变更成功的。
进一步的,网络设备向UE发送的主核心载波变更通知消息中可以包括专用前导序列。
进一步的,当网络设备向UE发送的主核心载波变更通知消息中包括专用前导序列时,在网络设备向UE发送主核心载波变更通知消息之后,网络设备可以根据UE采用该专用前导序列,基于新的主核心载波所对应的上行载波触发的RACH过程,确定UE主核心载波变更成功。
示例性的,UE采用专用前导序列触发的RACH过程具体的是非竞争RACH过程,其具体的可以包括,UE基于新的主核心载波所对应的上行载波发送所述专用前导序列给网络设备,网络设备收到所述专用前导序列后给UE发送确认信息,所述确认信息用于指示后续UE传输使用的上行授权和/或调整UE的上行发送定时。其中,网络设备可以是根据接收到的UE发送的专用前导序列确定UE主核心载波变更成功的。
进一步的,为了提高UE与网络设备通信的稳定性,当多个成员载波包括至少两个核心载波时,在第二种可能的实现方式中,UE可以主动触发主核心载波的变更,此时,在步骤101之后,网络设备可以接收UE的主核心载波发生变更的通知。
进一步的,在一种可能的实现方式中,网络设备接收UE的主核心载波发生变更的通知具体的可以为:网络设备接收UE基于新的主核心载波所对应的上行载波触发的RACH过程,这样,在网络设备接收到UE的主核心载波发生变更的通知之后,可以根据RACH过程确定主核心载波发生变更。
进一步的,在另一种可能的实现方式中,网络设备接收UE的主核心载波发生变更的通知具体的可以为:网络设备接收UE发送的上行消息;其中,该上行消息用于通知网络设备主核心载波发生变更,这样,在网络设备接收到UE的主核心载波发生变更的通知之后,可以根据该上行消息确定主核心载波发生变更。
进一步的,网络设备接收UE发送的上行消息具体的可以为:网络设备接收UE基于一个支持调度请求(英文:Scheduling Request,简称:SR)功能的辅核心载波发送的SR,并为UE分配的上行资源,此时网络设备便可以接收UE通过为其分配的上行资源发送的上行消息。
进一步的,当多个成员载波包括至少两个所述核心载波时,在步骤101之后,网络设备可以为UE配置测量事件;其中,该测量事件用于指示UE在邻小区的信号质量或信号强度大于任意一个核心载波对应的小区的信号质量或信号强度时,向网络设备上报测量报告。
其中,UE在接收到基站发送的测量事件之后,可以对邻小区的信号质量或信号强度进行测量,并根据接收到的测量事件确定在邻小区的信号质量或信号强度大于任意一个核心载波对应的小区的信号质量或信号强度时,向基站上报测量报告,以作为基站判断是否需进行核心载波变更的依据。

进一步的,为了提高UE与网络设备通信的稳定性,当多个成员载波包括至少两个核心载波时,在第一种可能的实现方式中,网络设备可以主动触发主核心载波的变更,具体的,在步骤201之后,UE可以接收网络设备发送的主核心载波变更通知消息,并根据接收到的主核心载波变更通知消息将主核心载波变更为新的主核心载波。

在这种场景下,为了能够使网络设备获知UE主核心载波变更成功,在UE根据主核心载波变更通知消息将主核心载波变更为新 的主核心载波之后,UE可以采用主核心载波变更通知消息中包括的专用前导序列,基于新的主核心载波所对应的上行载波触发RACH过程,以便网络设备根据专用前导序列确定主核心载波变更成功。
进一步的,为了提高UE与网络设备通信的稳定性,当多个成员载波包括至少两个核心载波时,在第二种可能的实现方式中,UE可以主动触发主核心载波的变更,具体的,步骤201之后,UE可以确定是否进行主核心载波变更,若确定出进行主核心载波变更,则从辅核心载波中确定新的主核心载波,并向网络设备通知主核心载波发生变更。

本发明另一实施例提供一种载波配置方法。其中,当网络设备为UE配置的载波聚合模型中包括多个成员载波,且多个成员载波中包括至少两个核心载波,至少两个核心载波中包括至少一个主核心载波时,为了提高UE与网络设备通信的稳定性,网络设备或者UE可以触发主核心载波变更,以在当前的主核心载波失效时,可以通过变更后的主核心载波继续通信。为了便于本领域技术人员的理解,本发明针对不同的应用场景对本发明的具体实施过程进行具体介绍,其中以网络设备是基站为例。
在第一种应用场景下,基站主动触发主核心载波变更,如图3所示,该场景下的载波配置方法具体可以包括:
301、基站将多个成员载波中具备上行传输功能和下行传输功能的成员载波确定为核心载波,并为UE配置载波聚合模型。
302、UE接收基站发送的载波聚合模型。
示例性的,基站为UE配置的载波聚合模型包括6个成员载波, 分别是CC0、CC1、CC2、CC3、CC4、CC5,其中,CC0、CC1、CC5均为核心载波,分别具备上行传输功能和下行传输功能,CC1为主核心载波,其余的成员载波CC2、CC3、CC4均为非核心载波,分别具备上行传输功能和/或下行传输功能。
303、UE根据载波聚合模型与基站进行数据传输。
其中,在UE接收到基站发送的载波聚合模型之后,便可以根据该载波聚合模型与基站进行数据传输。
具体的,在基站为UE配置了如步骤302中举例的聚合载波模型之后,UE便可以驻留在CC1对应的小区中,并可以读取CC1对应的小区的系统广播、还可以从CC1对应的小区中收取寻呼消息等等,并可以基于CC0、CC1、CC2、CC3、CC4、CC5,采用载波聚合技术与网络设备之间进行数据传输。
304、基站确定进行主核心载波变更。
其中,在UE接收到基站发送的载波聚合模型之后,为了确保与UE之间通信的可靠性,基站可以判断是否需进行主核心载波变更,并在确定需进行主核心载波变更之后,执行以下步骤305-步骤312。
305、基站从辅核心载波中确定新的主核心载波。
其中,辅核心载波为至少两个核心载波中除主核心载波外的其他的核心载波。具体的,在基站确定需进行主核心载波变更之后,可以从至少两个核心载波中除主核心载波外的其他的核心载波中确定新的主核心载波。基于步骤302中的举例,基站可以从CC0和CC5中确定一个核心载波作为新的主核心载波。
306、基站向UE发送主核心载波变更通知消息。
其中,主核心载波变更通知消息用于通知UE进行主核心载波变更。在基站从辅核心载波中确定出新的主核心载波之后,可以向UE发送主核心载波变更通知消息。
示例性的,若在步骤305中基站确定出的新的主核心载波为CC5,那么此时,基站可以向UE发送携带CC5的标识的主核心载 波变更通知消息。当然,若基站为UE配置的载波聚合模型中仅包括CC1和CC5两个核心载波,那么基站向UE发送的主核心载波变更通知消息便可以不用携带确定出的新的主核心载波(CC5)的标识。
进一步可选的,基站可以通过物理层信令或MAC层信令向UE发送主核心载波变更通知消息。
307、UE接收基站发送的主核心载波变更通知消息。
308、UE根据主核心载波变更通知消息将主核心载波变更为新的主核心载波。
其中,在UE接收到基站发送的主核心载波变更通知消息之后,便可以根据主核心载波变更通知消息将主核心载波变更为新的主核心载波。
示例性的,根据步骤306中的举例,此时UE可以根据接收到的主核心载波变更通知消息中携带的CC5的标识,将主核心载波由原先的CC1变更为CC5,并在变更完成之后,驻留在CC5对应的小区中,并可以读取CC5对应的小区的系统广播、还可以从CC5对应的小区中收取寻呼消息等等。
为了能够使基站获知UE主核心载波变更成功,在执行步骤308,UE根据主核心载波变更通知消息将主核心载波变更为新的主核心载波之后,若主核心载波变更通知消息中未包括专用前导序,可以执行步骤309-步骤310,若主核心载波变更通知消息中包括专用前导序,可以执行步骤311-步骤312,其中:
309、UE触发RACH过程。
310、基站根据UE触发的RACH过程,确定UE主核心载波变更成功。
311、UE采用专用前导序列,基于新的主核心载波所对应的上行载波触发RACH过程。
312、基站根据专用前导序列确定主核心载波变更成功。
需要说明的是,本发明实施例中步骤301-步骤312中的具体描 述,可以参考本发明其他方法实施例中对应步骤的具体描述,本发明实施例在此不再详细赘述。

并且,当多个成员载波包括至少两个核心载波时,基站可以在确定需进行主核心载波变更时,主动触发主核心载波变更流程,相较于现有技术中在主载波出现链路失效时,UE释放所有资源,导致通信中断相比,提高了UE与基站通信的稳定性。

示例性的,基于步骤404中的举例,UE可以从CC3、CC4中确定新的主核心载波,例如,基于CC3进行信号传输时信号的质量优于基于CC4进行信号传输时信号的质量,那么此时UE便可以将CC3确定为新的主核心载波。
在UE从辅核心载波中确定出新的主核心载波之后,UE可以向基站通知主核心载波发生变更,在一种可能的实现方式中,具体的通知过程可以包括以下步骤406-步骤408,在另一种可能的实现方式中,具体的通知过程可以包括以下步骤409-步骤411。

其中,该辅核心载波为除当前的主核心载波外的其他的核心载波。示例性的,基于步骤404中的举例,UE可以从CC3、CC4选出 一个支持SR功能的辅核心载,如CC4支持SR功能,然后基于CC4向基站发送SR,以触发上行授权请求。
409a2、基站为UE分配的上行资源。
其中,在UE基于支持SR功能的辅核心载波向基站发送SR之后,基站可以根据接收到的SR为UE分配上行资源,以便UE进行上行消息的传输。
