具体实施方式
为使本发明的上述目的、特征和有益效果能够更为明显易懂,下面结合附图对本发明的具体实施例做详细的说明。
根据第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)要求,下一代基站(next generation Node B,gNB)给终端设备配置的信道带宽决定了终端设备需满足的最低射频指标,且终端设备的部分载波带宽(bandwidth part,BWP)需在信道带宽(channel bandwidth,CBW)内。
当前协议对终端设备可以配置不同的上行链路BWP,BWP的配置粒度是RB级,即BWP可以包括若干个资源块(Resource Block,RB)。BWP是子带的一种表现形式,如果要求终端设备的射频指标 与子带相对应,那么即要求当子带的带宽为任意RB(小于等于带宽的最大RB数)时,终端设备都要满足对应的射频指标要求。当前协议终端设备会上报所支持的CBW,CBW的取值范围是,FR1(freqncy range 1)下为[5,10,15,20,25,30,40,50,60,80,100],FR2(freqncy range 2)下是[50,100,200],单位为MHz。如果要求终端设备的射频指标与子带相对应,相当于终端设备需支持现有取值外的其他CBW,终端设备实现难度大。如果限制子带的取值只能为FR1下为[5,10,15,20,25,30,40,50,60,80,100],FR2下是[50,100,200],则限制了资源调度的灵活性。子带是指信道带宽内的一段连续的频域资源。
在子带全双工方式下,以图1为例,终端设备的上行链路频域资源是中间的上行链路(UpLink,UL)子带时,比较gNB给终端设备配置不同的CBW时终端设备的射频指标要求,假设:
配置1:gNB给终端设备配置的是一个较窄CBW1,比如带宽与UL子带相同;
配置2:gNB给终端设备配置的是一个较宽CBW2,比如UL子带、以及UL和下行链路(DownLink,DL)子带都在CBW内。
终端设备工作在UL子带时,配置1下终端设备的带外频谱泄露要求相比于配置2严格,因此在配置1下,终端设备的上行链路对相邻DL子带或UL&DL子带的干扰比配置2下小,但在配置1下,终端设备只能调度在UL子带内;而在配置2下,终端设备就可以从UL子带切换到UL&DL子带。可见,现有的频域资源配置方式无法兼顾既要求终端设备的带外频谱泄露较小,又能够灵活进行不同子带之间的切换。
为此,本发明实施例提供一种频域资源配置方法及装置、以及一种频域资源切换方法及装置,既能降低终端设备的带外频谱泄露,又能够灵活进行不同频域资源之间的切换。具体地,网络设备在为终端设备配置频域资源时,同时为各频域资源配置其所在的信道带宽,生成频域资源集配置信息,并将该频域资源集配置信息下发给终端设 备。相应地,终端设备接收频域资源集配置信息根据该频域资源集配置信息,确定待切换的第一频域资源所在的信道带宽,切换到第一频域资源和第一频域资源所在的信道带宽。
需要说明的是,本发明实施例中所提到的第一频域资源是指信道带宽内的一段连续的频域资源,可以包括若干个RB,在具体应用中,也可以是前面提到的BWP或子带,也就是说,子带、BWP都是第一频域资源的表现形式。
另外,需要说明的是,网络设备可以为终端设备配置一个或多个上述第一频域资源及其所在的信道带宽,便于终端设备在不同的应用场景下可以灵活地进行不同频域资源之间的切换,更好地满足对不同应用场景下的频域资源及信道带宽需求。在本发明实施例中,所提到的网络设备可以是基站、gNB等。
下面分别从网络设备侧和终端设备侧详细说明本发明方案。
如图2所示,是本发明实施例频域资源配置方法的一种流程图,该实施例从网络设备侧说明为终端设备进行频域资源配置的过程,图2所示流程包括以下步骤:
步骤201,网络设备生成频域资源集配置信息,频域资源集配置信息用于指示一个或多个第一频域资源、以及各第一频域资源所在的信道带宽。
在具体实施时,可以采用多种方式生成频域资源集配置信息,将在后面详细说明。
步骤202,网络设备向终端设备发送频域资源集配置信息。
比如,可以通过无线资源控制(Radio Resource Control,RRC)消息将频域资源集配置信息发送给终端设备,也就是说,向终端设备发送无线资源控制消息,并在该无线资源控制消息中携带频域资源集配置信息。
需要说明的是,上述信道带宽可以根据终端设备的能力信息来确定。相应地,在本发明频域资源配置方法另一实施例中,还可以包括以下步骤:接收终端设备上报的能力信息;根据该能力信息确定信道带宽。
如图3所示,是本发明实施例频域资源切换方法的一种流程图,该实施例从终端设备侧说明终端设备根据网络设备配置的频域资源集进行频域资源切换的过程,图3所示流程包括以下步骤:
步骤301,终端设备接收网络设备发送的频域资源集配置信息,该频域资源集配置信息包括第一频域资源。
步骤302,终端设备根据上述频域资源集配置信息,确定第一频域资源所在的信道带宽。
前面提到,网络设备生成频域资源集配置信息的方式可以有多种,相应地,频域资源集配置信息中的具体内容及结构形式也会有所不同。相应地,在确定第一频域资源所在的信道带宽时也需要根据频域资源集配置信息的具体内容及结构形式进行适应性的变化,对此将在后面详细说明。
步骤303,终端设备切换到第一频域资源和该第一频域资源所在的信道带宽。
终端设备进行频域资源切换是由网络设备通过RRC、媒体存取控制地址(Media Access Control Address,MAC)控制单元(Control Element,CE)或者下行链路控制信息(Downlink Control Information,DCI)调度的,可指示终端设备切换到的频域资源,终端设备根据网络设备的指示进行切换。
由于对每个频域资源都配置了其所在的信道带宽,这样终端设备既能够灵活进行不同频域资源之间的切换,终端设备工作的信道带宽也随之变化,又能够减少带外频谱泄露。
在具体实施时,网络设备可以采用多种方式生成频域资源集配置 信息并下发给终端设备,相应地,终端设备基于不同形式的频域资源集配置信息,确定第一频域资源所在的信道带宽的方式也有所不同,对此下面举例说明。
第一种方式,参照图4,具体过程如下:
首先,在步骤40,终端设备向网络设备上报能力信息,上报的能力信息包括终端设备所支持的信道带宽。
相应地,在步骤41,网络设备根据终端设备上报的能力信息为该终端设备生成频域资源集配置信息,该频域资源集配置信息包括:一个或多个上述第一频域资源及上述第一频域资源所在的信道带宽。具体地,网络设备确定待配置的一个或多个第一频域资源、以及各第一频域资源所在的信道带宽信息,其中,信道带宽信息包括:中心频点和带宽;然后生成频域资源集配置信息。
需要说明的是,网络设备可以显式配置信道带宽的中心频点、包含的PRB数,也可通过配置信道带宽的起始PRB和终止PRB隐式配置信道带宽的中心频点和带宽,或者通过配置信道带宽的起始PRB/终止PRB和包含的PRB数隐式配置信道带宽的中心频点和带宽。
然后,在步骤42,网络设备将上述频域资源集配置信息发送给终端设备。
相应地,在步骤43,终端设备收到上述频域资源集配置信息后,保存该频域资源集配置信息。
在步骤44,网络设备发现终端设备在当前场景下需要进行频域资源切换,向终端设备发送切换指示,比如可以通过RRC、或者MAC CE、或者DCI指示终端设备进行频域资源切换,并指示终端设备需要切换到的第一频域资源。
相应地,在步骤45,终端设备收到网络设备的切换指示后,查找保存的频域资源配置信息,确定第一频域资源所在的信道带宽。
然后,在步骤46,终端设备切换到第一频域资源和该第一频域资源所在的信道带宽。
第二种方式,参照图5,具体过程如下:
首先,在步骤50,终端设备向网络设备上报能力信息,上报的能力信息包括终端设备所支持的信道带宽。
相应地,在步骤51,网络设备根据终端设备上报的能力信息为该终端设备生成信道带宽配置信息,该信道带宽配置信息包括至少两个信道带宽、以及各信道带宽的索引及信道带宽信息,上述信道带宽信息包括:中心频点和带宽。其中,网络设备配置信道带宽的方法可以参照步骤41的方法,此处不再赘述。另外,网络设备还要确定待配置的一个或多个第一频域资源及各第一频域资源所在的信道带宽,生成频域资源配置信息,该频域资源配置信息包括:一个或多个第一频域资源及上述第一频域资源所在的信道带宽索引。
在步骤52-54,网络设备和终端设备的描述可以参考步骤42-44,此处不再赘述。
在步骤55,终端设备收到网络设备的切换指示后,首先查找保存的频域资源配置信息,确定第一频域资源所在的信道带宽的索引。然后,查找保存的信道带宽配置信息,确定该索引对应的信道带宽,从而确定第一频域资源所在的信道带宽。
然后,在步骤56,终端设备切换到第一频域资源和该第一频域资源所在的信道带宽。
第三种方式,参照图6,具体过程如下:
首先,在步骤60,终端设备向网络设备上报能力信息,上报的能力信息包括终端设备所支持的信道带宽。

需要说明的是,在该方式下,每个第一频域资源的信道带宽隐式地配置为包含该第一频域资源的最窄信道带宽。比如,通过协议约定,默认配置的所有信道带宽中包含上述第一频域资源的最窄信道带宽为上述第一频域资源所在的信道带宽。当有大于等于2个带宽相同的最窄信道带宽时,则第一频域资源所在的信道带宽为各最窄信道带宽中起始PRB最大或最小的,具体可以由协议约定或网络设备配置是各最窄信道带宽中起始PRB最大的还是最小的。
在步骤62-64,网络设备和终端设备的描述可以参考步骤42-44,此处不再赘述。
在步骤65,终端设备收到网络设备的切换指示后,查找保存的频域资源配置信息,确定该频域资源配置信息中有上述第一频域资源,然后根据保存的信道带宽配置信息,确定包含该第一频域资源的所有信道带宽,并选择这些所有信道带宽中最窄的信道带宽作为该第一频域资源所在的信道带宽。当有大于等于2个带宽相同的最窄信道带宽时,则第一频域资源所在的信道带宽为各最窄信道带宽中起始PRB最大/最小的(由协议约定或网络设备配置是各最窄信道带宽中起始PRB最大的还是最小的)。
在步骤66,终端设备切换到上述第一频域资源和上述第一频域资源所在的信道带宽。

需要说明的是,在具体实施时,处理模块701可以采用多种方式生成频域资源集配置信息。相应地,上述频域资源集配置信息的具体内容及结构形式也可以有多种。比如:

第五信息处理单元,用于生成频域资源配置信息,该频域资源配置信息包括:一个或多个第一频域资源,第一频域资源所在的信道带宽为上述信道带宽配置信息中包含该第一频域资源的最窄信道带宽。当有大于等于2个带宽相同的最窄信道带宽时,则第一频域资源所在的信道带宽为各最窄信道带宽中起始PRB最大/最小的(由协议约定或网络设备配置是各最窄信道带宽中起始PRB最大的还是最小的)。
与上面实施例类似,在该实施例中,上述频域资源集配置信息包括上述的信道带宽配置信息和频域资源配置信息。相应地,上述发送模块702需要向终端设备发送上述资源配置信息和上述信道带宽配置信息。
在具体实施时,上述处理模块701可以根据终端设备的能力为其配置两个以上信道带宽。相应地,在本发明频域资源配置装置的另一实施例中,如图8所示,上述频域资源配置装置800包括以下各模块:
信息接收模块801,用于接收终端设备上报的能力信息;
处理模块701,用于根据终端设备上报的能力信息生成频域资源集配置信息,该频域资源集配置信息用于指示一个或多个第一频域资源、以及各第一频域资源所在的信道带宽;其中,信道带宽可以根据上述信息接收模块801接收到的终端设备的能力信息来确定;
发送模块702,用于向终端设备发送频域资源集配置信息。
需要说明的是,上述本发明频域资源配置装置各实施例中,发送模块702具体可以将上述频域资源集配置信息携带在RRC消息中发送。
相应地,本发明实施例还提供一种网络设备,可以包括上述任一实施例的频域资源配置装置。该网络设备可以是基站、gNB等设备。
相应地,本发明实施例还提供一种频域资源切换装置,如图9所示,是该频域资源切换装置的一种结构示意图。
在该实施例中,频域资源切换装置900包括以下各模块:

在一种非限制性实施例中,频域资源配置集信息包括:一个或多个第一频域资源、以及各第一频域资源所在的信道带宽信息,该信道带宽信息包括:中心频点和带宽。
相应地,在该实施例中,切换处理模块902可以直接根据上述频域资源配置集信息,即可确定第一频域资源所在的信道带宽。
在另一种非限制性实施例中,频域资源配置集信息包括:信道带宽配置信息和频域资源配置信息。其中,频域资源配置信息包括一个或多个第一频域资源、以及各第一频域资源所在的信道带宽的索引;信道带宽配置信息包括至少两个信道带宽、以及各信道带宽对应的索引及信道带宽信息,该信道带宽信息包括:中心频点和带宽。
相应地,在该实施例中,切换处理模块902可以先根据上述频域资源配置信息,确定第一频域资源所在的信道带宽的索引,然后再根据上述信道带宽配置信息,确定该索引对应的信道带宽。

相应地,由于默认配置的所有信道带宽中包含第一频域资源的最窄信道带宽为该第一频域资源所在的信道带宽。因此,在该实施例中,切换处理模块902可以先根据上述频域资源配置信息确定第一频域资源,然后根据上述信道带宽配置信息,确定包含第一频域资源的所有信道带宽,选择所有信道带宽中最窄的信道带宽作为第一频域资源所在的信道带宽。当有大于等于2个带宽相同的最窄信道带宽时,则第一频域资源所在的信道带宽为各最窄信道带宽中起始PRB最大/最小的(由协议约定或网络设备配置是各最窄信道带宽中起始PRB最 大的还是最小的)。
