信号处理方法、装置及终端

技术领域
本公开涉及通信感知技术领域,尤其涉及一种信号处理方法、装置及终端。
背景技术
在通信技术演进中,感知和通信一体化(Integrated Sensing and Communication,ISAC)是一个重要的候选演进特性。对于感知过程中,可以由感知设备主动发送感知信号并基于回波信号进行环境感知,也可以是感知设备根据接收到的感知信号或回波信号等进行环境感知。其中,在感知设备传输感知信号时,需要考虑信号的传输功率和传输资源(这里“传输”包括发送和/或接收,传输资源包含时域资源和/或频域资源)。从理论上来说,如果感知信号的发送功率越大则越能够提高感知结果的精度和准确度,反之感知结果的精度和准确度越低,但是如果感知信号的发送功率越大,则会对其他通信设备的干扰越大,不利于设备间空口共存。以终端作为感知设备为例,当终端发送感知信号的无线资源和网络设备(比如基站)共享时,由基站分配所有感知信号的无线资源位置,这样可以最大限度的避免设备间信号的相互干扰。但是感知资源的申请和分配过程,需要基站和终端进行信令交互,从而造成新的无线资源耗费,同时又增加感知业务的时延。

下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,并不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
以下针对本公开涉及的相关技术进行说明:
1、ISAC基本概念
ISAC的基本思想是在无线移动通信中,引入无线感知的功能。无线感知是指通过无线信号去感知环境信息,环境信息包括但不限于:环境物品的分布、大小、数量、温度,人的动作行为,甚至人的呼吸频率,心率等。无线感知的原理是对需要感知的环境发射无线信号,同时在接收端收集经过环境的反射、散射或多路径传输的无线信号。由于收集到的无线信号是经过环境参与的,即 收集到的无线信号携带了环境信息,这样在接收到经过环境的反射、散射或多路径传输的无线信号后,再经过相应的信号处理,即可获得环境特征,从而可以重建感知到的环境信息,比如识别出环境中的人与物,检测温度,检测到人的动作,甚至呼吸的频率,心跳的频率等。
无线感知通常分为:单站感知(monostatic)和双站感知。其中,单站感知是指基站或者终端主动发送感知信号,感知信号经过被感知物体反射后,由基站或者终端接收反射感知信号,例如:单站感知可以包括基于基站的单站感知(如图1a所示)、基于终端的单站感知(如图1b所示)。双站感知是指基站或者终端主动发送感知信号,感知信号经过无线信道由对方终端或者基站接收感知信号,例如:双站感知可以包括终端到终端的双站感知(即UE-UE双站感知,如图1c所示)、基站到基站的双站感知(即gNB-gNB双站感知,如图1d所示)、终端到基站的双站感知(即UE-gNB双站感知,如图1e所示)、基站到终端的双站感知(即gNB-UE双站感知,如图1f所示)。此外,无线感知还可以包括交互式感知,例如终端或基站主动发送感知信号,感知信号不经过感知物体而被基站或终端接收,如图1g所示。
2、无线感知精度
无线感知定位精度通常采用距离、速度和角度测量的均方根误差(σ)来描述。定位精度一方面取决于无线感知波形及天线参数(比如信号时宽、带宽及波束宽度),另一方面也取决于回波信号的信噪比,其计算公式如表1所示:
表1
其中,E为信号的能量,N0为单位带宽的噪声功率,c为光速,SNR为信 噪比:SNR=E/N0,τ为信号持续时间(非压缩的脉宽):τ=MTr
由上述表1可知,针对无线感知的精度,感知设备可以控制的变量有:信号带宽和发送功率(即信噪比),发送信号带宽越大,发送功率越大,则无线感知精度越高。
3、感知信号的发送功率和发送资源
在雷达感知系统中,发送频谱为专用,发送感知信号为大型基站或者飞机,对发送信号的功耗不敏感,同时认为感知业务对无线资源的需求比较少(即认为无线资源足够多),因而不对发送功率进行限制(如以最大功率进行发送),同时也无需无线资源分配过程。
为了满足感知业务质量指标的要求,同时减少对其他设备的干扰,需要确定“恰当”的发送感知信号的功率P_T,例如:当发送感知信号的设备是终端且感知模式是单站模式时,参见图2,针对感知信号的发送功率P_T而言:较大的发送功率P_T,虽然能够提高接收功率P_R的数值,从而提高感知信号的精度和准确度,但较大的发送功率P_T会带来对其他设备的干扰,同时也会减少终端的可工作时间,因而需要确定“恰当”的发送功率P_T。
另外,针对发送感知信号的资源位置(包含时域、频域):如果所有感知信号均由网路设备进行分配,虽然可以最大限度的避免设备间信号的相互干扰,但是在资源申请和分配过程也造成了信令耗费,同时又增加了感知业务的时延;并且当终端处于空闲态时,终端需要经过随机接入信道(Random Access Channel,RACH)过程进入连接态后,才能够和网络设备进行交互以申请分配无线资源。
本公开实施例提供了信号处理方法、装置及终端,用以解决目前感知信号传输存在资源耗费大,时延高的问题。其中,方法和装置(或终端)是基于同一申请构思的,由于方法和装置(或终端)解决问题的原理相似,因此方法和装置(或终端)的实施可以相互参见,重复之处不再赘述。
如图3所示,本公开的实施例提供了一种信号处理方法,包括以下步骤:
步骤31:终端确定感知信号的第一目标接收功率值。
可选地,所述第一目标接收功率值是接收感知信号的期望目标功率值(比如第一目标接收功率值可以采用P0target_UE表示)。例如:针对其他设备(比如其他终端或者网络设备等)发送感知信号时,所述终端期望接收所述感知信号的情况下,则P0target_UE即表示了终端能够接收到该感知信号的期望目标功率值;或者,针对所述终端发送感知信号后,该感知信号经过空口衰减和/或反射过程后,所述终端期望接收所述感知信号的情况下,则P0target_UE即表示了所述终端发送感知信号后,该感知信号经空口衰减和/或物体反射后,该终端能够接收该感知信号的期望目标功率值;或者,针对所述终端发送感知信号时,其他设备(比如其他终端或者网络设备等)期望接收所述感知信号的情况下,则P0target_UE即表示了其他设备能够接收到该感知信号的期望目标功率值。
这里,P0target_UE可以理解为:对于某一感知业务,从接收端设备(比如终端或者网络设备等)来看,感知信号的功率数值大于或等于该P0target_UE时,相关信号质量可以满足感知业务质量的要求,即该接收端设备能够有效进行感知信号的接收和计算,并输出符合关键指标质量要求的感知结果。
可选地,所述第一目标接收功率值由网络设备侧配置或指示,或者所述第一目标接收功率值由协议约定。例如:在所述第一目标接收功率值由网络设备侧配置或指示的情况下,可以是由网络设备向终端发送第一指示信息,该第一指示信息用于指示所述第一目标接收功率值。举例来说,网络设备侧配置或指示的第一目标接收功率值的数值范围可以为-220dBm到-90dBm。当网络设备侧没有配置或指示该第一目标接收功率值时,终端可以基于协议约定,确定所述第一目标接收功率值为默认数值,比如默认数值设置为-110dBm等,本公开实施例不以此为限。
步骤32:所述终端根据所述第一目标接收功率值,确定所述感知信号的第一发送功率值。
例如:终端可以考虑感知信号在传输过程中衰减量,对该第一目标接收功 率值进行补偿,得到所述感知信号的第一发送功率值。其中,感知信号在传输过程中的衰减量包括但不限于以下至少一项:感知信号从信号发送端到期望接收端的路损值、感知信号占用频域资源相关的第一参数值、其他功率相关的参数值等,本公开实施例不以此为限。
可选地,第一发送功率值可以理解为:在满足接收端设备接收感知信号的功率大于或等于第一目标接收功率值时,在发送该感知信号时所需要的发送功率的数值(比如该第一发送功率值可以采用PTToUE表示)。或者该第一发送功率值也可以理解为发送感知信号的实际功率值。例如:针对其他设备(比如其他终端或者网络设备等)发送感知信号时,所述终端期望接收所述感知信号的情况下,则PTToUE表示了其他设备发送感知信号需要满足的发送功率,以满足终端接收该感知信号的功率大于或等于P0target_UE;或者,针对所述终端发送感知信号后,该感知信号经过空口衰减和/或反射过程后,所述终端期望接收所述感知信号的情况下,则PTToUE即表示了所述终端发送感知信号需要满足的发送功率,以满足该感知信号经空口衰减和/或物体反射后,该终端接收该感知信号的功率大于或等于P0target_UE;或者,针对所述终端发送感知信号时,其他设备(比如其他终端或者网络设备等)期望接收所述感知信号的情况下,则PTToUE即表示了所述终端发送感知信号需要满足的发送功率,以满足其他设备接收该感知信号的功率大于或等于P0target_UE
步骤33:所述终端根据所述第一发送功率值,确定第一无线资源。
例如:所述终端可以根据所述第一发送功率值与参考功率值之间的大小关系,确定第一无线资源。举例来说,当PTToUE大于或等于该参考功率值时,表示发送的感知信号对其他设备的干扰比较大,此时可以由网络设备侧分配感知信号的发送和/或接收资源,以减少对其他设备的干扰。当PTToUE小于参考功率值时,表示发送的感知信号对其他设备的干扰比较小,此时终端可以自行确定感知信号的传输发送和/或接收资源,以减少信令开销,降低感知信号的传输时延。这里的其他设备可以指网络设备(比如gNB或者感知服务器等),或 者其他终端。
步骤34:所述终端在所述第一无线资源上发送和/或接收所述感知信号。
上述方案中,终端根据接收感知信号的第一目标接收功率值,确定发送感知信号的第一发送功率值,并根据该第一发送功率值,确定发送和/或接收感知信号的第一无线资源,以在所述第一无线资源上发送和/或接收感知信号,可以减少由网络设备分配感知信号的发送和/或接收资源的信令开销,并降低感知信号的传输时延,从而解决了目前感知信号传输存在资源耗费大,时延高的问题。

方式一:所述终端根据所述第一目标接收功率值以及第一集合,确定所述第一发送功率值,所述第一集合至少包括:第一路径的路损值、与所述感知信号占用频域资源相关的第一参数值。

其中,PLue-ue为所述第一路径的路损值。
可选地,所述第一路径是从所述感知信号的发送端到第一信号接收端的路径,所述第一信号接收端是感知信号的期望接收端。例如:针对其他设备发送感知信号时,所述终端期望接收所述感知信号的情况下(即其他设备为所述感知信号的发送端,终端为第一信号接收端),则所述第一路径即是感知信号从所述其他设备到所述终端所经过的路径;或者,针对所述终端发送感知信号后,该感知信号经过空口衰减和反射过程后,所述终端期望接收所述感知信号的情况下(即所述终端既为所述感知信号的发送端又为所述第一信号接收端),则所述第一路径即是所述感知信号从所述终端经反射物体后再到所述终端所经过的路径;或者,针对所述终端发送感知信号时,其他设备期望接收所述感知信号的情况下(即所述终端为所述感知信号的发送端,所述其他设备为所述第一信号接收端),则所述第一路径即是所述感知信号从所述终端到所述其他设 备所经过的路径。
可选地,所述第一路径的路损值小于或等于预设路损值;其中,所述预设路损值至少由感知业务支持的最远感知距离、RCS、所述感知信号的发送频段确定。也就是说,所述预设路损值可以由感知业务支持的最远感知距离、RCS、所述感知信号的发送频段确定,也可以由感知业务支持的最远感知距离、RCS、所述感知信号的发送频段以及其他路损相关参数确定等,本公开实施例不以此为限。
例如:以所述预设路损值由感知业务支持的最远感知距离、RCS、所述感知信号的发送频段确定为例,所述预设路损值具体可以是通过以下公式确定:
PLmax=PL(L)+PL(β*L)+-10lg(RCS)
其中,PLmax为预设路损值,PL()是与距离有关的路损计算公式,比如:PL(L)是距离L的路损值,PL(L)=32.4+17.3Log10(L)+20Log10(fc),fc为发送感知信号的载频;PL(β*L)是距离β*L的路损值,β*L是反射回波的路径长度。

可选地,所述第二目标接收功率值由网络设备侧配置或指示,或者所述第二目标接收功率值由协议约定。例如:在所述第二目标接收功率值由网络设备侧配置或指示的情况下,可以是由网络设备向终端发送第二指示信息,该第二指示信息用于指示所述第二目标接收功率值。举例来说,网络设备配置或指示的第二目标接收功率值可以是绝对数值(比如第二目标接收功率值的数值范围可以为-220dBm到-90dBm),或者网络设备配置或指示的第二目标接收功率值可以是感知信号产生干扰的功率门限值与用于通信的目标功率值P0target_C之间的差值或者称偏移值(offset),比如:P0target_gNB=P0target_C-offset;其中,P0target_C可以是相关技术中通信系统中指示的目标功率值。当网络设备侧没有配置该第二目标接收功率值时,终端可以基于协议约定,确定所述第二目标接收功率值为默认数值,比如默认数值设置为-120dBm等,本公开实施例不以此为限。
可选地,所述第二发送功率值可以理解为:在使得接收端设备接收到感知信号时,该感知信号在发送时的发送功率值(比如该第二发送功率值可以采用PTTogNB表示)。或者该第二发送功率值也可以理解为发送感知信号的参考功率值,也即满足发送感知信号时,避免对其他设备(这里其他设备即是感知信号的非期望接收设备)造成干扰。

例如:以终端根据第二目标接收功率值、第二路径的路损值、所述第一参数值、第一增益值,确定所述第二发送功率值为例,说明确定第二发送功率值的具体方法为:根据第二目标接收功率值、第二路径的路损值、所述第一参数值、第一增益值之和,确定所述第二发送功率值,如以下公式:
其中,PLue-gNB为所述第二路径的路损值,g(θd)为所述第一增益值,为所述第一参数值,这里也可以理解为与感知信号占用的频域资源相关函数的函数值。

例如:以终端根据第二目标接收功率值、第二路径的路损值,确定所述第二发送功率值为例,说明确定第二发送功率值的具体方法为:根据第二目标接收功率值、第二路径的路损值之和,确定所述第二发送功率值,如以下公式:
PTTogNB=P0target_gNB+PLue-gNB
其中,PLue-gNB为所述第二路径的路损值。
可选地,所述第二路径是从所述感知信号的发送端到第二信号接收端的路 径,所述第二信号接收端是被所述感知信号产生干扰的接收端,或者所述第二信号接收端也可以理解为感知信号的非期望接收端。例如:针对终端发送感知信号时,该感知信号经过空口衰减和/或反射过程后被网络设备接收的情况下(即所述终端为所述感知信号的发送端,所述网络设备为所述第二信号接收端),所述的第二路径即是感知信号从所述终端到所述网络设备所经过的路径。
可选地,所述第二路径的路损值可以由第一参考信号确定;
其中,所述第一参考信号包括以下至少一项:
为感知业务配置的参考信号;
用于确定PUCCH发送功率的参考信号;
用于确定PUSCH发送功率的参考信号;
用于获取MIB的同步信号块。
例如:终端可以根据索引号为qd的参考信号(即第一参考信号,也即是该索引号为qd的参考信号可以是为感知业务所配置的参考信号,或者在网络设备没有专门为感知业务配置参考信号时,该索引号为qd的参考信号也可以是用于计算PUCCH发送功率的参考信号qd,或者用于计算PUSCH发送功率的参考信号qd,或者用于获取MIB的同步信号块等)。举例来说,终端可以根据网络设备指示的索引号为qd的参考信号的发送功率与接收到该参考信号的接收功率之差,确定为所述第二路径的路损值等,该第二路径的路损值的单位是dB。
可选地,所述第一增益值是所述终端接收的所述第二信号接收端所发送的信号与所述终端接收的感知信号的波束方向差的增益值。例如:所述第一增益值小于或等于参考增益值,该参考增益值可以由网络设备指示或者根据波束增益确定等,本公开实施例不以为限。
举例来说,如图4所示,终端可以根据所述终端接收所述第二信号接收端(说明:图4中指的是网络设备)所发送的信号与所述终端接收的感知信号的波束方向差,计算得到一增益值。考虑增益值的单位是dB,因此在计算该增益值时需要对上述波束方向差进行等效转换,比如按照等效转换为上述 波束方向差对应的增益值,进而所述第一增益值可以由以下公式确定:
其中,g(θd)为所述第一增益值。
θd为所述终端接收所述第二信号接收端所发送信号与所述终端接收的感知信号的波束方向差。这里θd=θue-uegNB-ue,其中θue-ue即为终端接收感知信号的波束方向,θgNB-ue即为终端接收所述第二信号接收端所发送信号的波束方向。当θd=0时,表示两个波束方向相同,θd=π表示两个波束方向相反。θue-ue和θgNBgue可以由终端根据接收网络设备所发送信号与接收感知信号的波束方向自行确定。
θXdB是增益值衰减XdB对应的角度值,X为常数值(比如作为一种示例,X取值为3,当然也可以设置X取其他数值等,本公开实施例不以此为限)。这里θXdB或X可以由网络设备侧配置或指示;或者,θXdB或X根据波束增益设置等,本公开实施例不以此为限。
Gm是参考增益值。这里Gm也可以由网络设备侧指示或者根据波束增益确定等,比如设置Gm=20dB,本公开实施例不以此为限。
需要说明的是:上述描述θd,本质上是当终端发送感知信号波束有方向性时,发送波束的最佳波束方向(也即增益最大的方向)和感知信号到第二信号接收端(比如网络设备)的方向角差值,考虑到空间信道的互易性,本公开实施例中的θd是以两个接收波束的方向差来描述的。
可选地,上述确定第一发送功率值和/或确定第二发送功率值时,所使用到的第一参数值可以采用以下方式确定:
所述第一参数值由所述感知信号占用频域的RB的个数确定;
或者,
所述第一参数值由所述感知信号占用频域的RE的个数确定。
例如:可以根据感知信号占用频域的RB的个数相关的函数,确定所述第 一参考值(比如:该函数以RB的个数为变量,函数的值即为所述第一参数值),或者根据感知信号占用频域的RE的个数相关的函数,确定所述第一参考值(比如:该函数以RE的个数为变量,函数的值即为所述第一参数值)等,本公开实施例不以此为限。
可选地,所述第一参数值由所述感知信号占用频域的RB的个数确定,包括:
所述第一参数值由以下公式确定:
其中,为所述第一参数值,μ为子载波间隔配置参数,为所述感知信号占用频域的RB的个数。
例如:在感知信号的频域以RB为单位进行资源分配时,可以通过上述公式:确定所述第一参数值。该第一参数值的单位为分贝毫瓦(dBm)。为了调度灵活性,还可以对第一参数值的函数倍乘一个因子ad,该因子ad可以根据感知业务确定,或者可以由网络设备侧配置或指示,或者由终端根据感知服务质量要求自行确定等,本公开实施例不以为限。
可选地,所述第一参数值由所述感知信号占用频域的RE的个数确定,包括:
所述第一参数值由以下公式确定:
其中,为所述第一参数值,μ为子载波间隔配置参数,为所述感知信号占用频域的RE的个数。
例如:在感知信号的频域以RE为单位进行资源分配的情况下,可以通过上述公式:确定所述第一参考值。其中,12个RE组成一个RB。这里该第一参数值的单位为分贝毫瓦(dBm)。为了调度灵活性,还可以对第一参数值的函数倍乘一个因子ad,该因子ad可 以根据感知业务确定,或者可以由网络设备侧配置或指示,或者由终端根据感知服务质量要求自行确定等,本公开实施例不以为限。
可选地,作为一种实现方式:所述终端根据所述第一发送功率值和所述第二发送功率值的大小关系,确定第一无线资源,包括:
在所述第一发送功率值大于或等于所述第二发送功率值的情况下,所述终端将网络设备侧指示的无线资源确定为所述第一无线资源;例如:由网络设备侧指示特定的无线资源为所述第一无线资源。
和/或,
在所述第一发送功率值小于所述第二发送功率值的情况下,所述终端自行确定所述第一无线资源;例如:所述终端从网络设备侧配置或指示的多个无线资源中自行确定所述第一无线资源。
可选地,作为又一种实现方式:所述终端根据所述第一发送功率值和所述第二发送功率值的大小关系,确定第一无线资源,包括:
所述终端根据所述第一发送功率值和所述第二发送功率值的大小关系,确定无线资源获取方式;
所述终端根据所述无线资源获取方式,确定所述第一无线资源。
例如:所述资源获取方式可以包括但不限于以下至少一项:
第一获取方式,即是由网络设备侧指示所述第一无线资源;例如:由网络设备侧指示特定的无线资源为所述第一无线资源。
第二获取方式,即是由终端自行确定所述第一无线资源;例如:由终端从网络设备侧配置或指示的多个无线资源中自行确定所述第一无线资源。举例来说,
可选地,所述终端根据所述第一发送功率值和所述第二发送功率值的大小关系,确定第一无线资源,包括:
在所述第一发送功率值大于或等于所述第二发送功率值的情况下,所述终端确定无线资源获取方式为第一获取方式;其中,所述第一获取方式是网络设 备侧指示所述第一无线资源;例如:由网络设备侧指示特定的无线资源为所述第一无线资源。
和/或,

针对第一获取方式(Mode-1),也可以称为受限上行资源的确定模式。举例来说,如图5a所示,终端或其他设备发送的感知信号到达网络设备时的功率高于一定门限值(如大于或等于P0target_gNB),此时终端如果自行确定发送感知信号的无线资源,对网络设备的上行接收可能造成较大的干扰。为了降低此干扰,终端可以采用该Mode-1确定发送和/或接收所述感知信号的第一无线资源,也即由网络设备侧指示特定的无线资源(比如该特定的无线资源在网络设备侧分配给终端做感知信号发送时,不再分配给其他终端,则可以避免对网络设备的上行接收产生干扰)为所述第一无线资源,则此时终端只在网络设备侧指定的无线资源上发送感知信号。
针对第二获取方式(Mode-2),也可以称为自由上行资源的确定模式。举例来说,如图5b所示,终端或其他设备发送的感知信号到达网络设备时的功率低于一定门限值(如小于P0target_gNB),此时终端发送的感知信号到达基站的干扰水平较低,即对网络设备的上行接收造成的干扰较小,此时终端可以采用Mode-2确定发送和/或接收所述感知信号的第一无线资源,也即终端可以在网络设备配置或指示的感知信号的资源集合或资源池内自行选择无线资源,比如终端可以在该资源集合或资源池内选择任意的无线资源,发送和/或接收感知信号,而无需网络设备指定无线资源的过程。
需要说明的是,本公开实施例中在根据第一发送功率值和第二发送功率值的大小关系,确定第一无线资源;或者,根据第一发送功率值和第二发送功率 值的大小关系,确定无线资源获取方式的情况下:所述第一发送功率值可以采用上述确定第一发送功率值的方式一或方式二,所述第二发送功率值可以采用上述确定第二发送功率值的方式一或方式二或方式三。可选地,考虑确定第一发送功率值的方式二,以及确定第二发送功率值的方式三中均涉及相同的第一参数值,因此可以采用确定第一发送功率值的方式二以及确定第二发送功率值的方式三,确定的第一发送功率值和第二发送功率值的大小关系,来确定第一无线资源或者确定无线资源获取方式等,本公开实施例不以此为限。
可选地,所述终端在所述第一无线资源上发送所述感知信号,包括:
所述终端在第一无线资源上以所述第一发送功率值或者所述第二发送功率值发送感知信号;
所述终端接收所述感知信号经反射后的回波信号;
所述终端根据所述回波信号的接收功率值,调整所述第一发送功率值或者所述第二发送功率值;

具体的,所述终端在执行感知业务过程中(比如在检测到感知物体并对其进行跟踪时),终端在所述第一无线资源上发送所述感知信号时,可以根据实际检测到反射信号(或回波信号),对所发送感知信号的发送功率PTToUE进行调整。例如:终端从初始发送功率P_T开始发送感知信号;其中初始发送功率P_T为第一发送功率值或者所述第二发送功率值。进一步地,终端接收所述感知信号的反射信号(或回波信号),并根据所述反射信号(或回波信号)计算得到接收功率值P_R。终端根据P_R逐渐增加或者逐渐减少发送感知信号的发送功率P_T,直到P_R和P0target_UE差值满足一定的条件(比如P_R和P0target_UE之间的差值处于第一数值范围delta1~delta2内,其中delta1和delta2可以由网络设备侧配置或指示)。
可选地,所述终端在第一无线资源上以所述第一发送功率值或者所述第二 发送功率值发送感知信号的确定方式,包括:
终端确定在所述第一无线资源上以所述第一发送功率值发送感知信号;
或者,
终端确定在所述第一无线资源上以所述第二发送功率值发送感知信号;
或者,
所述终端确定在所述第一无线资源上以所述第一发送功率值和所述第二发送功率值中的较小者,发送感知信号;
或者,
所述终端确定在所述第一无线资源上以所述第一发送功率值和所述第二发送功率值中的较大者,发送感知信号。
可选地,所述终端根据所述回波信号的接收功率值,调整所述第一发送功率值或者所述第二发送功率值,包括:
在所述回波信号的接收功率值与所述第一目标接收功率值之间的差值处于第一数值范围的情况下,所述终端按照第一步长调整所述第一发送功率值或者所述第二发送功率值。
例如:所述第一数值范围为:delta1~delta2,可选地,所述第一数值范围由网络设备侧配置或指示,比如该delta1和delta2由网络设备侧配置或指示等。
可选地,所述第一步长为所述第一数值范围中的最大数值和/或最小数值。比如:在所述回波信号的接收功率值与所述第一目标接收功率值之间的差值大于delta1的情况下,则可以按照第一步长为delta1逐渐减小发送功率P_T;和/或,在所述回波信号的接收功率值与所述第一目标接收功率值之间的差值小于delta2的情况下,则可以按照第一步长为delta2逐渐增加发送功率P_T。
如图6所示,终端在第一无线资源上发送感知信号的过程如下:
设置初始发送功率P_T=P_init;其中,P_init可以取上述公式计算的第一发送功率值PTToUE,或者第二发送功率值PTTogNB
终端从功率数值P_init开始发送信号;
终端接收感知信号的反射信号,并根据接收到的反射信号计算接收功率P_R,并判断是否P_R>P0_target_UE+delta1
如果是,则根据P_T=P_T-delta1重新确定发送功率,并按照重新确定的发送功率P_T继续发送感知信号;
如果否,则继续判断是否P_R<P0_target_UE-delta2;
如果是,则根据P_T=P_T+delta2重新确定发送功率,并按照重新确定的发送功率P_T继续发送感知信号;
如果否,则流程结束。
