无线通信过程中,终端设备通过向接入网设备发送信道探测信号来估计上行信道质量,该信道探测信号可以是探测参考信号(Sounding Reference Signal,SRS),接入网设备根据信道估计结果向终端设备分配用于发送上行数据的频域资源。
在第五代移动通信技术(5th-Generation,5G)或者新一代无线接入技术(New Radio Access Technology,NR)中可能会存在如下两种情况:1、接入网设备将系统带宽分为若干个固定宽度的子带,并将这些子带分配给对应的终端设备,其中每个子带内用于发送控制信息的上行控制信道和发送数据信息的上行数据信道相对固定,上行数据信道位于子带内,上行控制信道位于子带的两侧,其中该上行控制信道可以是物理上行控制信道(Physical Uplink Control Channel,PUCCH),该上行数据信道可以是物理上行共享信道(Physical Uplink Share channel PUSCH)。2、接入网设备未向终端设备分配固定带宽的子带,上行控制信道与上行数据信道的频域资源位置相邻,并且上行控制信道位于上行数据信道的两侧。基于此,如何在这两种情况下发送信道探测信号是亟待解决的问题。

为了解决在上述两种情况下如何发送信道探测信号的问题。本申请提供一种信道探测信号的发送方法及终端设备。其中本申请应用于如下的通信系统中:图1为本申请实施例提供的一种通信系统的示意图,如图1所示,终端设备120通过接入网设备110接入到无线网络,以通过无线网络获取外网(例如因特网)的服务,或者通过无线网络与其它终端设备120通信。接入网设备110可以向终端设备120发送下行参考信号,终端设备120基于该下行参考信号进行下行信道测量,并上报信道状态信息(Channel State Information,CSI)给接入网设备110。此外,终端设备120可以向接入网设备110发送信道探测信号,以便接入网设备进行上行信道测量。
具体地,未来5G或者NR网络中将会存在以下两种资源分布方式:图2A为本申请一实施例提供的一种资源分布示意图,如图2A所示,接入网设备为终端设备分配固定带宽的频域资源a或者子带a,上行数据信道占用频域资源a的部分带宽。当终端设备需要在上行控制信道上发送控制信息时,上行控制信道也占用频域资源a的部分带宽。其中上行控制信道位于频域资源a的两侧。当然,终端设备也可以只在上行控制信道上发送上行 控制信息,而不在上行数据信道上发送上行数据信息,在这种情况下,图2A所示的上行数据信道的频域位置为预留状态。终端设备也可以只在上行数据信道上发送上行数据信息,而不在上行控制信道上发送上行控制信息,在这种情况下,图2A所示的上行控制信道的频域位置为预留状态。图2B为本申请另一实施例提供的一种资源分布示意图,如图2B所示,接入网设备不为终端设备分配固定带宽的频域资源a或者子带a,而是为上行数据信道分配频域资源。当终端设备需要在上行控制信道上发送控制信息时,接入网设备还为上行控制信道分配频域资源。其中上行控制信道位于上行数据信道的两侧。当然,终端设备也可以只在上行控制信道上发送上行控制信息,而不在上行数据信道上发送上行数据信息,在这种情况下,图2A所示的上行数据信道的频域位置为预留状态。终端设备也可以只在上行数据信道上发送上行数据信息,而不在上行控制信道上发送上行控制信息,在这种情况下,图2A所示的上行控制信道的频域位置为预留状态。
基于图2A所示的资源分布情况,本申请提供一种信道探测信号的发送方法。本申请中的信道探测信号用于测量上行信道的质量。该信道探测信号可以是SRS或者NR-SRS等。本申请对该信道探测信号的名称不做限制。具体地,图3为本申请一实施例提供的信道探测信号的发送方法的流程图。如图3所示,该方法包括如下流程:
步骤S301:终端设备获取接入网设备为终端设备配置的第一频域资源的频域位置信息和第二频域资源的频域位置信息。
其中,第一频域资源为接入网设备为终端设备配置的可工作的频域资源。上行数据信道和/或上行控制信道位于第一频域资源内,其中上行控制信道位于第一频域资源的两侧。如图2A所示,频域资源a即为第一频域资源。上行数据信道和上行控制信道位于第一频域资源内,上行控制信道位于频域资源a的两侧。第一频域资源的频域位置信息用于指示第一频域资源的频域位置。该第一频域资源的频域位置信息包括:第一频域资源的最小频域位置和最大频域位置。第一频域资源的频域位置信息还可以包括:第一频域资源的带宽。
该上行数据信道用于发送上行数据信息。例如:该上行数据信道可以是PUSCH或者是NR-PUSCH,本申请对该上行数据信道的名称不做限制。该上行数据信道用于发送上行控制信息。例如:该上行控制信道可以是PUCCH或者NR-PUCCH,本申请对该上行控制信道的名称不做限制。
可选地,第一频域资源的频域位置信息可以携带在物理层信令或者高层信令中。例如:第一频域资源的频域位置信息可以携带在无线资源控制(Radio Resource Control,RRC)信令或者媒体接入控制(Media Access Control,MAC)信令或者控制指示(Downlink Control Indication,DCI)信令中。
第二频域资源为接入网设备向终端设备指示的用于发送信道探测信号的频域资源。即第二频域资源为名义上用于发送信道探测信号的频域资源。然而,最后终端设备不一定在该第二频域资源上发送信道探测信号。如图2A所示,频域资源c即为第二频域资源。第二频域资源的频域位置信息用于指示第二频域资源的频域位置。该第二频域资源的频域位置信息包括:第二频域资源的最小频域位置和最大频域位置。第二频域资源的频域位置信息还可以包括:第二频域资源的带宽。
可选地,第二频域资源的频域位置信息可以携带在物理层信令或者高层信令中。例如:第二频域资源的频域位置信息可以携带在RRC信令或者MAC信令或者DCI信令中。
需要说明的是,本申请对终端设备获取第一频域资源的频域位置信息和获取第一频域资源的频域位置信息的时间先后顺序不做限制。
步骤S302:终端设备根据第一频域资源的频域位置和第二频域资源的频域位置的关系确定目标频域资源。
步骤S303:终端设备在目标频域资源上向接入网设备发送信道探测信号。
结合步骤S302和步骤S303进行说明:该目标频域资源用于发送信道探测信号。其中步骤S302具体包括如下几种情况:
第一、若第二频域资源的频域位置在第一频域资源的频域位置之内,则终端设备确定第二频域资源为目标频域资源。
具体地,当第二频域资源为图2A中最上方的频域资源c时,即第二频域资源的频域位置在第一频域资源的频域位置之内,这种情况表示接入网设备指示发送信道探测信号的频域资源在第一频域资源之内,因此终端设备可以将第二频域资源作为目标频域资源。并在该目标频域资源上发送信道探测信号。
第二、若第二频域资源的部分资源的频域位置在第一频域资源的频域位置之内,或者第二频域资源的频域位置不在第一频域资源的频域位置之内,则终端设备将确定第二频域资源在第一频域资源中的映射资源,将该映射资源作为目标频域资源。其中当第二频域资源的部分资源的频域位置在第一频域资源的频域位置之内,且第二频域资源的最小频域位置小于第一频域资源的最小频域位置时,第二频域资源在第一频域资源中的映射方式可以是:将第二频域资源的频域位置向第一频域资源的最大频域位置方向平移M1带宽,其中M1为第二频域资源不在第一频域资源的这部分频域资源的带宽。例如:如图2A所示,中间的频域资源c对应的映射资源可以为最上方的频域资源c。当第二频域资源的部分资源的频域位置在第一频域资源的频域位置之内,且第二频域资源的最大频域位置大于第一频域资源的最大频域位置时,第二频域资源在第一频域资源中的映射方式可以是:将第二频域资源的频域位置向第一频域资源的最小频域位置方向平移M2带宽,其中M2为第二频域资源不在第一频域资源的这部分频域资源的带宽。当第二频域资源的频域位置不在第一频域资源的频域位置之内,且第二频域资源的最小频域位置小于第一频域资源的最小频域位置时,第二频域资源在第一频域资源中的映射方式可以是:确定第二频域资源的最小频域位置与第一频域资源的最小频域位置的频域间隔M3,将第二频域资源的频域位置向第一频域资源的最大频域位置方向平移M3带宽。当第二频域资源的频域位置不在第一频域资源的频域位置之内,且第二频域资源的最大频域位置大于第一频域资源的最大频域位置时,第二频域资源在第一频域资源中的映射方式可以是:确定第二频域资源的最大频域位置与第一频域资源的最大频域位置的频域间隔M4,将第二频域资源的频域位置向第一频域资源的最小频域位置方向平移M4带宽。
第三、若第二频域资源的部分资源的频域位置在第一频域资源的频域位置之内,或者第二频域资源的频域位置不在第一频域资源的频域位置之内,则终端设备根据上行数据信道或者上行控制信道和信道探测信号的时间间隔,以及终端设备的频点切换时长确定目标频域资源。
其中,如图2A所示,中间的频域资源c为第二频域资源的一种情况,即该第二频域资源的部分资源的频域位置在第一频域资源的频域位置之内。最下方的频域资源c为第二 频域资源的再一种情况,即该第二频域资源的频域位置不在第一频域资源的频域位置之内。
当终端设备仅在上行数据信道上发送上行数据信息,而不在上行控制信道上发送上行控制信息时,该时间间隔为上行数据信道和信道探测信号的时间间隔。当终端设备仅在上行控制信道上发送上行控制信息,而不在上行数据信道上发送上行数据信息时,该时间间隔为上行控制信道和信道探测信号的时间间隔。当终端设备既在上行数据信道上发送上行数据信息,而且还在上行控制信道上发送上行控制信息时,并且当在上行数据信道上发送上行数据信息的开始发送时间与在上行控制信道上发送上行控制信息的开始发送时间相同,且在上行数据信道上发送上行数据信息的发送结束时间早于在上行控制信道上发送上行控制信息的发送结束时间,该时间间隔为上行控制信道和信道探测信号的时间间隔。相反,当终端设备既在上行数据信道上发送上行数据信息,而且还在上行控制信道上发送上行控制信息时,并且当在上行数据信道上发送上行数据信息的开始发送时间与在上行控制信道上发送上行控制信息的开始发送时间相同,且在上行数据信道上发送上行数据信息的发送结束时间晚于在上行控制信道上发送上行控制信息的发送结束时间,该时间间隔为上行数据信道和信道探测信号的时间间隔。当终端设备既在上行数据信道上发送上行数据信息,而且还在上行控制信道上发送上行控制信息时,并且当在上行数据信道上发送上行数据信息的开始发送时间与在上行控制信道上发送上行控制信息的开始发送时间相同,且在上行数据信道上发送上行数据信息的发送结束时间与在上行控制信道上发送上行控制信息的发送结束时间相同,该时间间隔为上行数据信道和信道探测信号的时间间隔;或上行控制信道和信道探测信号的时间间隔。其中如图2A所示,由于上行数据信道和上行控制信道在时域上重叠,因此上行数据信道和信道探测信号的时间间隔与上行控制信道和信道探测信号的时间间隔相同。
可选地,上述上行控制信道和信道探测信号的时间间隔可以是在上行控制信道上发送上行控制信息的发送结束时间与信道探测信号的开始发送时间之间的时间间隔。或者,可以是在上行控制信道上发送上行控制信息的开始发送时间与信道探测信号的开始发送时间之间的时间间隔。或者,上述上行控制信道和信道探测信号的时间间隔是根据以下至少一个时间间隔计算得到的。如:在上行控制信道上发送上行控制信息的发送结束时间与信道探测信号的开始发送时间之间的时间间隔。和/或,在上行控制信道上发送上行控制信息的开始发送时间与信道探测信号的开始发送时间之间的时间间隔。同样的,上述上行数据信道和信道探测信号的时间间隔与上述上行控制信道和信道探测信号的时间间隔定义方式类似,在此不再赘述。
本申请对时间间隔不做限制。该时间间隔携带在高层信令或者物理层信令中;例如:该时间间隔可以携带在RRC信令或者MAC信令或者DCI信令中。或者,该时间间隔是终端设备预先设定的,例如:该时间间隔是终端设备从通信协议中确定的。
可选地,终端设备的频点切换时长为终端设备从第一频域资源的中心频点向第三频域资源的中心频点切换时所需的时长;其中,第三频域资源包括第二频域资源。该第三频域资源的带宽可以小于或者等于第一频域资源的带宽相同。
一种可选方式,终端设备根据上行数据信道或者上行控制信道和信道探测信号的时间间隔,以及终端设备的频点切换时长确定目标频域资源包括:若时间间隔大于或者等于频 点切换时长,则终端设备切换至第三频域资源的中心频点,并确定第二频域资源为目标频域资源;若第二频域资源的部分频域资源的频域位置在第一频域资源的频域位置之内,且时间间隔小于频点切换时长,则确定部分频域资源为目标频域资源。
具体地,当第二频域资源的部分资源的频域位置在第一频域资源的频域位置之内,或者第二频域资源的频域位置不在第一频域资源的频域位置之内时,只要上述时间间隔大于或者等于频点切换时长,则终端设备切换至第三频域资源的中心频点,并确定第二频域资源为目标频域资源。也就是说,只要上述时间间隔大于或者等于频点切换时长,表示在发送信道探测信号之前,终端设备可以切换至第三频域资源,而该第三频域资源包括第二频域资源。这种情况下,终端设备可以将该第二频域资源作为目标频域资源,并在该目标频域资源上发送信道探测信号。
若第二频域资源的部分频域资源的频域位置在第一频域资源的频域位置之内,且时间间隔小于频点切换时长,则确定部分频域资源为目标频域资源。例如:如图2A所示,第二频域资源的部分频域资源c’的频域位置在第一频域资源a的频域位置之内,但是上述时间间隔小于频点切换时长,表示终端设备在发送信道探测信号之前,不能完全切换至第三频域资源。这种情况下,终端设备可以不进行频点切换,而是确定上述部分频域资源为目标频域资源。并在该目标频域资源上发送信道探测信号。或者,若第二频域资源的部分频域资源的频域位置在第一频域资源的频域位置之内,且时间间隔小于频点切换时长,则不发送信道探测信号。
另一种可选方式,终端设备根据上行数据信道或者上行控制信道和信道探测信号的时间间隔,以及终端设备的频点切换时长确定目标频域资源包括:若时间间隔大于或者等于频点切换时长,则终端设备切换至第三频域资源的中心频点,并确定第二频域资源为目标频域资源;若第二频域资源的部分频域资源的频域位置在第一频域资源的频域位置之内,且时间间隔小于频点切换时长,则终端设备将确定第二频域资源在第一频域资源中的映射资源,将该映射资源作为目标频域资源。其中第二频域资源在第一频域资源中的映射方式与上述第二频域资源在第一频域资源中的映射方式相同,在此不再赘述。
而当终端设备在该目标频域资源上发送信道探测信号时,终端设备可以采用频分多路复用(Frequency Division Multiplexing,FDM)或者码分多路复用(Code Division Multiplexing,CDM)方式发送信道探测信号。本申请对发送信道探测信号的方式不做限制。
进一步地,若第二频域资源的频域位置不在第一频域资源的频域位置之内,且时间间隔小于频点切换时长,则不发送信道探测信号。
需要说明的是,本申请实施例提供的信道探测信号的发送方法可以适用于周期性的信道探测信号或者非周期性的信道探测信号。例如:当该方法只适用于非周期性的信道探测信号时,该非周期性的信道探测信号可以在第一频域资源之内发送,也可以在第一频域资源之外发送。而对于周期性的信道探测信号只能在第一频域资源之内发送。
本申请实施例提供一种信道探测信号的发送方法,包括:终端设备获取接入网设备为所述终端设备配置的第一频域资源的频域位置信息和第二频域资源的频域位置信息。终端设备根据第一频域资源的频域位置和第二频域资源的频域位置的关系确定目标频域资源。终端设备在目标频域资源上发送信道探测信号。即本申请实施例提供了基于5G或者NR 中的一种资源分布方式的信道探测信号的发送方法。从而解决在该资源分布方式下如何发送信道探测信号的问题。
基于图2B所示的资源分布情况,本申请提供一种信道探测信号的发送方法。本申请中的信道探测信号用于测量上行信道的质量。该信道探测信号可以是SRS或者NR-SRS等。本申请对该信道探测信号的名称不做限制。具体地,图4为本申请另一实施例提供的信道探测信号的发送方法的流程图。如图4所示,该方法包括如下流程:
步骤S401:终端设备获取第一频域资源的频域位置信息和第二频域资源的频域位置信息。
该第一频域资源为终端设备当前占用的频域资源。所谓终端设备当前占用的频域资源是指:终端设备当前用于发送上行数据信息的上行数据信道和/或当前用于发送上行控制信息的上行控制信道的频域资源。具体地,当终端设备仅在上行数据信道上发送上行数据信息,而不在上行控制信道上发送上行控制信息时,第一频域资源为上行数据信道的频域资源。当终端设备仅在上行控制信道上发送上行控制信息,而不在上行数据信道上发送上行数据信息时,第一频域资源为上行控制信道的频域资源。当终端设备既在上行数据信道上发送上行数据信息,还在上行控制信道上发送上行控制信息时,第一频域资源为上行数据信道和上行控制信道的频域资源。如图2B所示,第一频域资源即为上行数据信道和上行控制信道的频域资源。第一频域资源的频域位置信息用于指示第一频域资源的频域位置。该第一频域资源的频域位置信息包括:第一频域资源的最小频域位置和最大频域位置。第一频域资源的频域位置信息还可以包括:第一频域资源的带宽。

具体地,当第二频域资源为图2B中最上方的频域资源c时,即第二频域资源的频域位置在可工作的频域资源b的频域位置之内,该可工作的频域资源b是以第一频域资源的最大频域位置为可工作的频域资源的最大频域位置,以最大发送带宽为可工作的频域资源的带宽。这种情况表示接入网设备指示发送信道探测信号的频域资源在可工作的频域资源b之内,因此终端设备可以将第二频域资源作为目标频域资源。并在该目标频域资源上发送信道探测信号。
第二、若第二频域资源的部分频域资源的频域位置在可工作的频域资源的频域位置之内,或者第二频域资源的频域位置不在可工作的频域资源的频域位置之内,则终端设备将确定第二频域资源在可工作的频域资源中的映射资源,将该映射资源作为目标频域资源。其中当第二频域资源的部分资源的频域位置在可工作的频域资源的频域位置之内,且第二频域资源的最小频域位置小于可工作的频域资源的最小频域位置时,第二频域资源在可工作的频域资源中的映射方式可以是:将第二频域资源的频域位置向可工作的频域资源的最大频域位置方向平移M1带宽,其中M1为第二频域资源不在可工作的频域资源的这部分频域资源的带宽。例如:如图2B所示,中间的频域资源c对应的映射资源可以为最上方的频域资源c。当第二频域资源的部分资源的频域位置在可工作的频域资源的频域位置之内,且第二频域资源的最大频域位置大于可工作的频域资源的最大频域位置时,第二频域资源在可工作的频域资源中的映射方式可以是:将第二频域资源的频域位置向可工作的频域资源的最小频域位置方向平移M2带宽,其中M2为第二频域资源不在可工作的频域资源的这部分频域资源的带宽。当第二频域资源的频域位置不在可工作的频域资源的频域位置之内,且第二频域资源的最小频域位置小于可工作的频域资源的最小频域位置时,第二频域资源在可工作的频域资源中的映射方式可以是:确定第二频域资源的最小频域位置与可工作的频域资源的最小频域位置的频域间隔M3,将第二频域资源的频域位置向可工作的频域资源的最大频域位置方向平移M3带宽。当第二频域资源的频域位置不在可工作的频域资源的频域位置之内,且第二频域资源的最大频域位置大于可工作的频域资源的最大 频域位置时,第二频域资源在可工作的频域资源中的映射方式可以是:确定第二频域资源的最大频域位置与可工作的频域资源的最大频域位置的频域间隔M4,将第二频域资源的频域位置向可工作的频域资源的最小频域位置方向平移M4带宽。
