Description

一种激活频域资源的方法、设备及系统 技术领域
本申请实施例涉及通信技术领域,尤其涉及一种激活频域资源的方法、设备及系统。
背景技术
为适配具有不同带宽能力的终端,第五代(5th-Generation,5G)新空口(New Radio,NR)协议中引入了带宽部分(Bandwidth part,BWP)的概念。如:将整个小区的上行带宽/下行带宽配置为多个上连续的部分,配置后的上行带宽称之为上行BWP,配置后的下行带宽称之为下行BWP。终端可以工作在激活的上行BWP上,在激活的上行BWP上发送上行数据;或者工作在激活的下行BWP上,在激活的下行BWP上接收下行数据。
目前,主要由网络侧设备(如基站)为终端配置BWP或激活终端的BWP。以基站激活终端的BWP为例,基站主动向终端发送携带有激活的BWP的信息的激活信息,终端接收到该激活信息后,根据激活信息中携带的激活的BWP的信息,激活BWP,在激活的BWP上工作,即完全由网络侧设备决定终端所使用的BWP。
随着5G NR协议的发展,在新的5G NR协议中支持基站为终端调度多个激活的BWP,使终端同时工作在多个BWP上。虽然,终端同时工作在多个激活的BWP上可以获得更大的带宽,提高终端的峰值速率,但由基站激活多个BWP很可能会导致终端功耗过大和/或过热等一系列问题,不满足终端的通信要求。

作为一种可实现方式,处理器201可以包括一个或多个CPU,例如图2中的CPU0和CPU1。作为另一种可实现方式,通信设备200可以包括多个处理器,例如图2中的处理器201和处理器207。作为再一种可实现方式,通信设备200还可以包括输出设备205和输入设备206。

下面结合图1所示的通信系统,对本申请实施例提供的激活频域资源的方法进行描述。作为一种可实现方式,下述实施例中的终端为图1中的任一终端,接入网设备为图1中的接入网设备。
图3为本申请实施例提供的一种激活频域资源的方法流程图,该方法由终端和接入网设备交互执行,用于配置或激活终端的频域资源单元,如图3所示,该方法可以包括:
步骤301:终端确定第一信息。
其中,第一信息可以包括用于请求接入网设备配置或者终端的激活频域资源单元的信息,如:第一信息可以为配置或激活请求,该配置或激活请求包括用于请求接入网设备配置或激活终端的频域资源单元的信息。
或者,第一信息可以包括第一辅助信息,该第一辅助信息用于指示接入网设备配置或者激活终端的频域资源单元,当接入网设备接收到第一信息后,可以根据第一信息包括的第一辅助信息配置或激活终端的频域资源单元。需要说明的是,在本申请中,第一辅助信息是一种用于指示接入网设备配置或者激活终端的频域资源单元的信息,该信息除命名为第一辅助信息外,还可以有其他命名,例如激活辅助信息等不同表述,也可以包含于本申请的思想范围内。
其中,在本申请的所有实施例中,接入网设备激活的终端的频域资源单元可以包括在接入网设备预先配置给终端的多个频域资源单元中。例如,终端上线后,接入网设备可以预先配置4个频域资源单元,这4个频域资源单元在终端未使用时可以处于未激活状态,当终端需要与接入网设备通过频域资源单元通信或者根据自身工作情况调整已激活的频域资源单元时,终端可以向接入网设备请求激活这4个频域资源单元中的一个或者多个频域资源单元。
其中,第一辅助信息可以根据终端的第一状态确定,终端的第一状态可以的电量小于等于预设电量阈值,终端的温度大于等于预设温度阈值,终端的信号强度小于等于预设信号强度中的一种或者多种。其中,预设电量阈值、预设温度阈值、预设信号强度可以根据需要进行设置,不予限制。当终端的电量小于等于预设电量阈值时,表示终端的电量比较低,当终端的温度大于等于预设温度阈值时,表示终端过热,当终端的信号强度小于等于预设信号强度时,表示终端信号较差。
第一辅助信息可以包括或指示以下信息中的至少一个:终端期望的(preferred)频域资源单元的带宽(或最大带宽),终端期望的频域资源单元的个数(或最大个数),终端期望的频域资源单元的总带宽(或最大总带宽)。第一辅助信息还可以包括或指示终端期望的频域资源单元的指示信息。第一辅助信息也可以包括或指示终端期望的PDCCH的盲解次数或最大盲解次数等。第一辅助信息也可以包括或指示终端的工作状态信息,即第一辅助信息指示终端的工作状态。具体的,第一辅助信息的相关描述可参照图4~图13所述。
步骤302:终端向接入网设备发送第一信息,接入网设备接收第一信息。
一种可能的设计中,终端的处理器在检测到其处于第一状态时,主动触发其将第一信息携带在空口信令中向接入网设备发送,这一发送过程对用户来说是不感知的。
又一种可能的设计中,当终端检测到其处于第一状态时,通过用户界面(User Interface,UI)向用户发送状态信息以及提示信息,用户可以结合状态信息以及提示信息向终端发送确认指令,终端根据用户发送的确认指令,将第一信息携带在空口信令中向接入网设备发送,即终端在接收到用户的指示后才向接入网设备发送第一信息,提高用户体验。
其中,状态信息用于指示终端处于第一状态,可以用图标或者文字等形式来表示;提示信息可以为终端当前处于第一状态是否切换终端的工作模式等信息,终端的工作模式与终端同时激活的频域资源单元的数量和大小对应,通常,终端的工作模式可以分为两种,一种工作模式对应的同时激活的频域资源单元的数量较多,带宽较大,另一种工作模式对应的同时激活的频域资源单元的数量较少,带宽较小。
如图3a所示,假设终端为手机,终端的第一状态为终端的电量较低,此时,手机的处理器在检测到手机电量较低时,在显示屏上通过不停的闪烁电池图标(图3a中3011所示)或者将电池图标显示为红 色提示用户手机当前电量较低,同时,在显示屏上弹出一提示框(如图3a中3012所示),提示用户手机电量较低,是否切换手机的工作模块,若用户点击提示框中的按钮“是”,则手机的处理器确定切换手机的工作模式,执行步骤301所述过程。
步骤303:接入网设备根据第一信息,配置或激活频域资源单元。
具体的,接入网设备根据第一信息,配置或激活频域资源单元可以包括:
第一信息包括第一辅助信息,接入网设备根据第一辅助信息配置或激活终端的频域资源单元。其中,针对不同的第一辅助信息,接入网设备配置或激活频域资源单元时的选择准则是不同的,具体的,可参照图4~图13所述方案。
以接入网设备激活终端的频域资源单元为例,进一步的,在步骤303之后,还可以包括:接入网设备向终端发送激活信息,其中,激活信息可以用于指示激活的至少一个频域资源单元,激活信息可以包括至少一个频域资源单元的标识,频域资源单元的标识用于标识频域资源单元,频域资源单元的标识可以为频域资源单元的编码、频域资源单元的索引号等等,不予限制。
其中,激活信息可以携带在无线资源控制无线资源控制(Radio Resource Control,RRC)信令中,或者下行控制信息(Downlink Control Information,DCI)中下发给终端。其中,当激活信息携带在RRC信令中下发给终端,终端根据激活信息激活频域资源单元后,还可以向接入网设备发送RRC配置响应,以指示终端成功激活频域资源单元。
进一步的,图3所示方法还可以包括:
终端检测到终端的电量高于预设电量阈值,以及终端的温度低于预设温度阈值;
终端向接入网设备发送第二信息,其中,第二信息包括用于指示接入网设备根据终端的能力信息激活频域资源单元的信息,或者包括终端的第二辅助信息。
其中,第二辅助信息用于指示接入网设备根据终端的能力信息配置或激活频域资源单元;具体的,第二辅助信息可以包括终端当前的工作状态信息(如电量信息、温度信息等),或指示终端的工作状态(如电量正常或温度正常等)。
其中,终端的能力信息用于指示终端的通信能力,可以为终端的出厂时配置的通信能力,其中所述通信能力具体的可以为基带处理能力、射频能力等。
如此,当终端电量恢复或过热情况改善时,终端上报信令解除接入网设备需根据终端上报的信息配置或激活频域资源单元的限制,使接入网设备根据终端的能力信息自主选择配置或激活的频域资源单元带宽和数目。
需要说明的是,终端不会同时发送所述第一信息和第二信息;接入网设备根据当前收到的是第一信息或是第二信息进行处理。
基于图3所示方法,终端主动向接入网设备发送包括用于请求配置或激活终端的频域资源单元的信息,或者包括终端的频域资源单元的第一辅助信息的第一信息,使接入网设备在接收到终端发送的第一信息后,根据第一信息配置或激活频域资源单元,即在接入网设备配置或激活频域资源单元时,需要结合终端上传的信息进行配置或者激活,而不是如现有技术一样,由接入网设备自主地配置或激活终端的额频域资源带宽,如此,可以避免因接入网设备自主配置或激活的频域资源单元造成的不满足终端的通信要求的问题。
下面结合图4~图13,以第一信息包括第一辅助信息,第一辅助信息包括或指示终端期望的频域资源单元的最大带宽,终端期望的频域资源单元的最大个数,终端期望的频域资源单元的最大总带宽中的一个或者多个信息,或者终端期望的频域资源单元的指示信息,或者终端期望的PDCCH的最大盲解次数,或者终端的工作状态信息,接入网设备根据第一辅助信息激活终端的频域资源单元为例,对本申请 实施例提供的激活频域资源的方法进行阐述。
图4为本申请实施例提供的又一种激活频域资源的方法流程图,如图4所示,该方法可以包括:
步骤401:终端检测到终端处于第一状态。
其中,第一状态的描述可参照图3中所述,不再赘述。
步骤402:终端向接入网设备发送第一辅助信息,第一辅助信息包括或指示终端期望的频域资源单元的最大带宽。
其中,终端期望的频域资源单元的最大带宽为终端希望激活的频域资源单元中的最大带宽,接入网设备激活的频域资源单元的带宽不期望超过该最大带宽。
其中,频域资源单元的最大带宽可以是带宽的具体取值,如100MHz;也可以用物理资源块(Physical Resource Block,PRB)的个数表示,如50表示最大带宽为50个物理资源块对应的带宽;还可以根据接入网设备预先配置给终端的频域资源单元确定,将最大带宽对应的频域资源单元的编号上报给接入网设备,以便接入网设备根据该编号确定终端期望的频域资源单元的最大带宽。例如,接入网设备预先配置给终端的频域资源单元为频域资源单元1~频域资源单元4四个频域资源单元,频域资源单元1的带宽大小为150M,频域资源单元2的带宽大小为100M,频域资源单元3的带宽大小为50M,频域资源单元4的带宽大小为30M,此时,如果终端期望的频域资源单元的最大带宽为100M,则终端可以将频域资源单元2的编号2携带在第一信息中发送给接入网设备,以使得接入网设备根据编号2识别出终端期望的频域资源单元的最大带宽为频域资源单元2的带宽100M。
例如,假设频域资源单元为BWP,终端请求激活下行(DownLink,DL)BWP以及上行(UpLink,DL)BWP,终端期望的BWP的最大带宽对应为BWP的编号,且第一辅助信息携带在空口信令的某个信元中,则该信元的格式如下所示:
Figure PCTCN2019082378-appb-000001
其中,reducedBwpBandwidthDL表示终端期望的下行BWP的最大带宽,maxNrofBWPs表示接入网设备预先配置给终端的BWP的最大编号,reducedBwpBandwidthDL INTEGER(0..maxNrofBWPs)
OPTIONAL表示终端期望的下行BWP的最大带宽可以为编号从0~maxNrofBWPs中任一编号对应的BWP的带宽。
同理,reducedBwpBandwidthUL INTEGER(0..maxNrofBWPs)OPTIONAL表示终端期望的上行BWP的最大带宽可以为编号从0~maxNrofBWPs中任一编号对应的BWP的带宽。
步骤403:接入网设备接收第一信息,根据终端期望的频域资源单元的最大带宽激活频域资源单元。
可选的,接入网设备根据终端期望的频域资源单元的最大带宽激活频域资源单元包括:接入网设备选择带宽小于等于终端期望的频域资源单元的最大带宽的频域资源单元进行激活。例如,终端期望的频域资源单元的最大带宽为100M,则接入网设备激活的频域资源单元的带宽要小于等于100M。
步骤404:接入网设备向终端发送激活信息。
其中,激活信息可参照图3中所述,不再赘述。
需要说明的是,图4中终端期望的频域资源单元的最大带宽可替换为终端期望的频域资源单元的带宽,即终端为接入网设备指定激活的频域资源单元的带宽大小,使激活的频域资源单元的带宽满足终端的要求。例如,终端期望的频域资源单元的带宽为50M,则接入网设备激活的频域资源单元的带宽也必 须为50M。
基于图4所示方法,终端可以通过限制频域资源单元的带宽,使网络侧设备激活小带宽的频域资源单元,从而降低终端功耗和减少发热。
需要说明的是,终端期望的频域资源单元的最大带宽可设置为协议支持的最大值,从而在效果上相当于对频域资源单元的带宽不做限制,网络侧设备可根据终端的能力信息配置或激活频域资源单元。
图5为本申请实施例提供的又一种激活频域资源的方法流程图,如图5所示,该方法可以包括:
步骤501:终端检测到终端处于第一状态。
其中,第一状态的描述可参照图3中所述,不再赘述。
步骤502:终端向接入网设备发送第一辅助信息,第一辅助信息包括或指示终端期望的频域资源单元的最大个数。
其中,终端期望的频域资源单元的最大个数为终端希望激活的频域资源单元的最大个数,接入网设备激活的频域资源单元的总个数不期望超过该最大个数。具体的,终端期望的频域资源单元的最大个数根据接入网设备预先配置给终端的频域资源单元确定,可选的,终端期望的频域资源单元的最大个数不超过接入网设备预先配置给终端的频域资源单元的个数。终端可以将终端期望的频域资源单元的最大个数的具体取值直接上报给接入网设备。例如,接入网设备预先配置给终端的频域资源单元为频域资源单元1~频域资源单元4四个频域资源单元,则终端期望的频域资源单元的最大个数可以为1~4中的任一取值。
例如,假设频域资源单元为BWP,终端请求激活下行(DownLink,DL)BWP以及上行(UpLink,DL)BWP,且第一辅助信息携带在空口信令的某个信元中,则该信元的格式如下所示:
Figure PCTCN2019082378-appb-000002
其中,reducedBwpActiveNumDL表示终端期望的BWP的最大个数,maxNrofActiveBWPs表示协议支持的接入网设备预先配置给终端的BWP的最大个数,reducedBwpActiveNumDL INTEGER(1..maxNrofActiveBWPs)OPTIONAL表示终端期望的BWP的个数可以为1~maxNrofActiveBWPs中任一取值。
reducedBwpActiveNumUL INTEGER(1..maxNrofActiveBWPs)OPTIONAL表示终端期望的同时激活的上行BWP的最大个数可以为1~maxNrofActiveBWPs中任一取值。
步骤503:接入网设备接收第一信息,根据终端期望的频域资源单元的最大个数激活频域资源单元。
可选的,接入网设备根据终端期望的频域资源单元的最大个数包括:接入网设备选择个数小于等于终端期望的频域资源单元的最大个数的频域资源单元进行激活。如,终端期望的频域资源单元的最大个数为3,则接入网设备激活的频域资源单元的个数小于等于3个。
步骤504:接入网设备向终端发送激活信息。
其中,激活信息可参照图3中所述,不再赘述。
需要说明的是,图5中终端期望的频域资源单元的最大个数可替换为终端期望的频域资源单元的个数,即终端为接入网设备指定激活的频域资源单元的个数,使激活的频域资源单元的个数满足终端的要求。例如,终端期望的频域资源单元的个数为3,则接入网设备激活的频域资源单元的个数也必须为3个。
基于图5所示方法,终端可以通过限制频域资源单元的个数,使网络侧设备激活的频域资源单元个数较少,从而降低终端功耗和减少发热。
需要说明的是,图5中终端期望的频域资源单元的最大个数可设置为协议支持的最大值,从而在效果上相当于对频域资源单元的个数不做限制,网络侧设备可根据终端的能力信息配置或激活频域资源单元。
图6为本申请实施例提供的又一种激活频域资源的方法流程图,如图6所示,该方法可以包括:
步骤601:终端检测到终端处于第一状态。
其中,第一状态的描述可参照图3中所述,不再赘述。
步骤602:终端向接入网设备发送第一辅助信息,第一辅助信息包括或指示终端期望的频域资源单元的最大总带宽。
其中,终端期望的频域资源单元的最大总带宽可以指:终端希望激活的所有频域资源单元的总带宽的最大值,接入网设备激活的频域资源单元的总带宽不期望超过该最大总带宽。终端可以将终端期望的频域资源单元的最大总带宽的具体取值(如200M)直接上报给接入网设备;或用PRB个数表示最大总带宽,如100表示最大总带宽为100个物理资源块对应的带宽。
假设频域资源单元为BWP,终端请求激活下行(DownLink,DL)BWP以及上行(UpLink,DL)BWP,终端期望的BWP的最大总带宽用物理资源块的个数表示,且第一辅助信息携带在空口信令的某个信元中,则该信元的格式如下所示:
Figure PCTCN2019082378-appb-000003
其中,maxNrofPhysicalResourceBlocks表示协议支持的最大物理资源块数目;reducedTotalBwpBWDL表示终端下行期望的BWP的最大总带宽,单位为物理资源块;reducedTotalBwpBWDL INTEGER(1..maxNrofPhysicalResourceBlocks)OPTIONAL表示终端下行期望的BWP的最大总带宽可以取值为1~协议支持的最大物理资源块数目。
reducedTotalBwpBWUL表示终端上行期望的最大总带宽,单位为物理资源块;reducedTotalBwpBWUL INTEGER(1..maxNrofPhysicalResourceBlocks)OPTIONAL表示终端上行期望的BWP的最大总带宽可以取值为1~协议支持的最大物理资源块数目。
步骤603:接入网设备接收第一信息,根据终端期望的频域资源单元的最大总带宽激活频域资源单元。
可选的,接入网设备根据终端期望的频域资源单元的最大总带宽包括:接入网设备选择总带宽小于等于终端期望的频域资源单元的最大总带宽的频域资源单元进行激活。如,终端期望的频域资源单元的最大总带宽为330M,则接入网设备激活的频域资源单元的总带宽小于等于330M。
步骤604:接入网设备向终端发送激活信息。
其中,激活信息可参照图3中所述,不再赘述。
需要说明的是,图6中终端期望的频域资源单元的最大总带宽可替换为终端期望的频域资源单元的总带宽,即终端为接入网设备指定激活的频域资源单元的总带宽,使激活的频域资源单元的总带宽满足终端的要求。例如,终端期望的频域资源单元的总带宽为200M,则接入网设备激活的频域资源单元的总带宽也必须为200M。
基于图6所示方法,终端可以通过限制频域资源单元的总带宽,使网络侧设备激活的频域资源单元的总带宽降低,从而降低终端功耗和减少发热。
需要说明的是,图6中终端期望的频域资源单元的最大总带宽可设置为协议支持的最大值,从而在效果上相当于对频域资源单元的总带宽不做限制,网络侧设备可根据终端的能力信息配置或激活频域资源单元。
图7为本申请实施例提供的又一种激活频域资源的方法流程图,如图7所示,该方法可以包括:
步骤701:终端检测到终端处于第一状态。
其中,第一状态的描述可参照图3中所述,不再赘述。
