下面对上述部分内容进行进一步解释：
感知区域标识对应的感知区域为待感知的目标区域，可以是提前划分好的，具体可以包括如下多种方式：
多个基站覆盖区域(小区)组成一个感知区域，关联一个感知区域标识nareaID，如图6a所示，每个六边形区域表示基站覆盖区域，相同数字区域表示同一个感知区域。特别的，可以是将接入网通知区域(RAN-based notification area，RNA)作为一个感知区域，将RNA ID作为所述感知区域标识。
单个基站覆盖区域(小区)包含多个感知区域，关联多个感知区域标识，例如以基站为原点，对其覆盖范围进行栅格化划分为多个感知区域，每个区域关联一个区域ID记为nareaID，如图6b，虚线表示基站覆盖区域，每个方格表示划分的感知区域。
也可以是直接利用和基站位置无关的地理区域标识例如经纬度等，或坐标位置，生成区域ID nareaID。
还可以是相对于基站的不同角度范围关联到不同的区域ID nareaID，例如方位角x1°～x2°、俯仰角y1°～y2°对应感知区域ID1，其中，x和y为实数。
当进行同一感知区域的多设备联合感知时，多个设备使用共同的区域ID生成感知信号。
可选地，该感知信号的生成参数和小区标识或终端标识无关，即不同发送设备可以使用相同的感知信号生成参数，便于进一步构建码分正交的感知信号(例如基于相同的生成参数生成第一感知信号，不同设备使用相同的第一感知信号和不同的OCC序列生成相互正交的第二感知信号并用于感知测量)，接收设备可以基于相同的感知信号生成参数以及码分正交方式获取感知信号并进行测量，减小不同设备间信号的干扰且能够减小信令开销，提升测量效率。

基于感知目标标识(或者感知目标关联的Tag标识)生成，包括：
信号发送设备获取感知目标的标识，不同感知目标对应不同的感知目标ID ntargetID，其中感知目标的确定可以是基于已有测量结果获取的先验信息，例如基站A通过全向波束发送感知测量信号进行初步测量，基站A获取距离-多普勒图(或者距离-角度图等)，根据所述距离-多普勒图确定目标个数，并为每个目标分配ID；又或者，基站A通过全向波束发送感知测量信号进行初步测量，接收设备(例如其他基站或终端)获取距离-多普勒图(或者距离-角度图等)，根据所述距离-多普勒图确定目标个数，并为每个目标分配ID，进而将目标ID和/或目标相关信息通知给发送基站。

x1(n+31)＝(x1(n+3)+x1(n))mod 2
x2(n+31)＝(x2(n+3)+x2(n+2)+x2(n+1)+x2(n))mod 2
其中，n＝0,1,...,MPN-1，MPN为序列长度。NC＝1600，第一个m序列x1(n)的初始化方式为x1(0)＝1,x1(n)＝0,n＝1,2,...,30；第二个m序列x2(n)的初始化方式为
进一步地，对所述PN序列进行调制得到第一序列/第二序列，例如进行QPSK调制：M为第一序列/第二序列长度。
或者，根据初始值cinit生成伪随机序列，根据伪随机序列c(i)通过π/2-BPSK调制生成序列然后根据序列生成基序列：然后根据基序列生成第一序列/第二序列：M为第一序列/第二序列长度。该方式生成的第一序列/第二序列相比于前一种方式具有较小的峰均功率比(Peak to Average Power Ratio，PAPR)，具有更高的功放效率，有利于提升感知测量覆盖性能。

Chirp信号可以用如下公式表示：
其中，A0为幅度，fc为起始频率，|k|＝B/T为调频斜率，其中，B为带宽，T为Chirp持续时间(即FMCW的调频周期)，例如若第一序列基于Chirp信号生成，则Chirp持续时间等于OFDM符号时长。
其中，不同调频斜率与第三信息关联，例如不同感知业务对带宽和Chirp持续时间要求不同，即对调频斜率要求不同，可以是不同感知业务ID与不同调频斜率存在预设映射关系；又例如，对于两端口信号发送，端口0和端口1采用的Chirp信号的调频斜率可以分别是k0和-k0，即互为相反数。
不同起始频率与第三信息关联，例如不同感知区域和起始频率存在预设映射关系。
实施例四：
该实施例中主要描述基于时域或频域相位调制的感知信号具体生成方式。
对于基于时域相位调制的感知信号生成，第一序列为频域生成的序列。或者，第一序列为时域生成的序列经过傅里叶变换后得到的频域序列，可用于基于离散傅里叶变换的扩频正交频分复用(Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing，DFT-s-OFDM)波形。

基于对CSI-RS进行时域相位调制生成感知信号，具体如下：
确定CSI-RS信号资源配置，如根据时延/距离分辨率需求确定CSI-RS带宽(占用的RB个数)；或，根据时延/距离测量范围需求确定CSI-RS频域密度(每个RB内CSI-RS个数)；或，根据多普勒/速度分辨率需求确定相干处理时间窗口大小，进而确定CSI-RS发送的时域行为：对于周期或半持续发送的CSI-RS，可以是每个相干处理时间窗口对应的发送周期数，对于非周期发送的CSI-RS，可以是至少一个非周期CSI-RS资源/资源集合对应的总时长；或，根据时延/距离测量范围需求确定CSI-RS时域密度，对应同一CSI-RS资源的时域周期或多个CSI-RS资源/资源集合的最小时域间隔；或，确定其他CSI-RS时频域资源参数，例如起始RE(RB内偏移)、起始符号/时隙(符号/时隙偏移)等；或，根据感知目标个数、感知用户(设备)数确定CSI-RS端口数、CDM类型。
生成CSI-RS信号，然后根据上述实施例二所述的方法，对每个相干处理时间窗口内的至少一个CSI-RS进行沿时域维度的相位调制，得到所述感知信号。
对于设备A发设备B收感知模式(或设备A发设备A收感知模式)，设备A发送感知信号之前，需要获取所述感知信号配置信息，或，通知设备B所述感知信号配置信息。所述感知信号配置信息除了CSI-RS信号资源配置相关信息(信道状态信息测量配置(CSI-MeasConfig)中相关配置信息)外，还包括以下至少一项：
标识信息，表示所述至少一个CSI-RS信号资源为进行了相位调制，用于感知测量的信号；
相干处理窗口信息，包括窗口大小、起始位置、窗口索引等；
第二序列的信息。
其中，第二序列类型和生成方式等与最大支持端口数或端口索引相关联，这些信息可以不需要专门通知。
实施例六：
该实施例主要描述多端口/多用户感知设计。
对于多端口或多用户感知时的设计可以是：时分复用，和/或，频分复用，和/或，码分复用。
具体可以应用于多个感知设备同时工作或者单个设备感知多个目标(例如不同端口信号采用不同波束发送，感知不同目标)的场景。
对于码分复用，不同端口/用户对应的二维感知信号占用的时频域资源相同，具体实现方式可以是：
方式一、第一序列不同，和/或，第二序列不同。若基于PN序列生成，通过不同扰码初始值(cinit)区分；若基于ZC序列生成，通过不同循环移位值和/或根序列号区分；若基于Chirp信号生成，则通过不同的调频斜率和/或起始频率区分。如前面实施例所述，即第一信息中包含天线端口索引。
例如：不同端口对应的感知信号使用不同的第一序列和不同的第二序列，其中第一序列和第二序列为PN序列，第一序列对应的初始值为：
或
或
或
第二序列对应的初始值为：
或
或
或
其中x、y、z、A是非负正整数，例如可令A＝31，nport为端口索引，为物理小区标识，为每个时隙的符号个数，为无线帧内的时隙索引，l为时隙内的符号索引，nperiod为相干处理时间窗口索引。
又例如：不同端口对应的感知信号使用相同的第一序列和不同的第二序列，其中第一序列和第二序列为PN序列，第一序列对应的初始值为：
或
第二序列对应的初始值为：
或
或
或
又例如：不同端口对应的感知信号使用不同的第一序列和相同的第二序列，其中第一序列和第二序列为PN序列，第一序列对应的初始值为：
或
或
或
第二序列对应的初始值为：
或
又例如，采用ZC序列时，可以是不同端口对应的第一序列/第二序列采用相同的ZC基序列，进而得到基序列0≤n<M，其中不同端口的根序列号q相同，进一步地，通过循环移位得到不同端口对应的第一序列/第二序列：0≤n<M，循环移位值的计算方式可以是例如：为与端口索引关联的循环移位值。
此外，采用ZC序列时，还可以是不同端口对应的第一序列/第二序列采用不同的ZC基序列，即不同端口对应的根序列号不同，其中与端口索引关联。
此外，采用ZC序列时，还可以是不同端口对应的第一序列/第二序列采用不同的ZC基序列和不同的循环移位值，其中根序列号和循环移位值与端口索引关联。
方式二、第一序列和第二序列相同，采用OCC码区分多端口。
以2端口频域OCC为例，根据第一序列和第二序列得到二维感知信号z(n,m),0≤n≤N-1,0≤m≤M-1后，端口0不同符号对应的频域序列与[+1+1,…,+1,+1]相乘并映射到不同子载波上，端口1不同符号对应的频域序列与[+1-1,…,+1,-1]相乘并映射到不同子载波上。
也可以采用时域OCC，或者同时采用时域OCC和频域OCC，原理类似不再赘述。方式三、第一序列不同，和/或，第二序列不同，同时采用OCC码区分多端口。
具体的，例如，不同端口对应的第一序列相同但采用不同的OCC码进行频域OCC映射，不同端口对应的第二序列不同，具体感知信号生成方法参见前面实施例。以协议定义的CSI-RS Row3为例，基于频域码分多路复用(code division multiplexing，CDM)(例如：频域OCC调制)可支持2端口CSI-RS发送，采用频域OCC调制的两个端口在同一符号上对应相同的第一序列；另外，基于第二序列A和第二序列B(第二序列A与第二序列B具有较低的互相关峰值)对窗口内进行了频域OCC调制的不同符号的第一序列进行时域相位调制。
还可以是采用相同第一序列和第二序列的端口对应同一端口集合，同一端口集合内不同端口之间采用OCC区分，不同端口集合采用的第一序列和/或第二序列不同。
假设存在2个待感知目标，采用2端口信号进行感知，时频域二维感知信号设计中两个port信号对应的第一序列和第二序列不同(均采用QPSK调制PN序列，cinit不同)，其中每个符号的第一序列独立生成，然后沿时域维度基于第二序列进行相位调制；CSI-RS采用OCC码区分2个端口信号。如图8a至图8d所示，图8a至图8d为基于第二序列(PN序列)进行时域相位调制生成的所述二维感知信号测量性能与当前通信系统CSI-RS测量性能对比，包括时延、多普勒、角度测量均方根误差(Root mean squared error，RMSE)以及定位RMSE，可以看出所提方案相比于原有参考信号设计提升了感知性能。
又例如，时频域二维感知信号设计中两个port信号对应的第一序列相同且利用频域OCC码区分两个port，第二序列不同(采用未经过QPSK调制的PN序列(实序列)，cinit不同)，其中每个符号的第一序列独立生成，然后沿时域维度基于第二序列进行相位调制；作为对比的CSI-RS采用OCC码区分2个端口信号。如图9a至图9d所示，图9a至图9d为基于第二序列(PN序列)进行时域相位调制生成的所述二维感知信号测量性能与当前通信系统CSI-RS测量性能对比，包括时延、多普勒、角度测量RMSE以及定位RMSE，可以看出所提方案相比于原有参考信号设计提升了感知性能。
实施例七：
该实施例主要描述基于序列截取得到第一序列、第二序列。
第一序列或第二序列的生成还可以是基于对长度更长的特殊设计序列进行截取得到。
例如，根据系统带宽生成长度为N0的第三序列，然后根据感知信号频域资源信息(带宽、频域资源个数、频域密度)对第三序列进行截取或抽取(降采样)得到第一序列。其中，不同时域位置(例如不同符号)对应的第三序列独立生成，即生成M个第三序列，然后截取得到M个第一序列。
根据感知测量总持续时长生成长度为M0的第四序列(或者是按其他规则例如每X个无线帧对应的时长生成第四序列)，然后根据感知信号时域资源信息(相干处理时间窗口长度、时域密度、周期、时域资源长度)对第四序列进行截取或抽取(降采样)得到第二序列。
其中，第三序列、第四序列的生成可参考实施例一，即：
若基于PN序列生成(例如进行正交相移键控(quadrature phase shift keying，QPSK)调制)，则所述PN序列的初始值和/或，PN序列的本原多项式与第一信息关联；
若基于ZC序列生成，则所述ZC序列的根序列号和/或循环移位值与第一信息关联；
若基于Chirp信号生成，则所述Chirp信号的调频斜率和/或起始频率与第一信息关联。
需要注意的是，第三序列和第四序列可以基于不同类型的序列生成，例如第三序列基于PN序列生成，第四序列基于ZC序列生成。
第三信息的定义如实施例一所述，其中，对于第三序列、第四序列的生成，第三信息中还包括以下至少一项：
频域起始位置，例如A(PonitA)；
相对于频域起始位置的偏移量；
时域起始位置，例如每K个(K≥1)无线帧的起始时域位置；
相对于时域起始位置的偏移量。
可选地，对于第三序列、第四序列的生成，第一信息中可以不包含相干处理时间窗口索引或感知资源块索引，此时第三序列和第四序列可能对应与多个相干处理时间窗口或感知资源块。以时域维度对应的第四序列和第二序列为例，说明感知信号与相干处理时间窗口的关系，如图4所示，不同相干处理时间窗口在时域上可以是不重叠的，也可以是部分重叠的(即以滑动窗口的方式计算感知测量结果，且滑动的步长小于相干处理时间窗口长度,适用于例如轨迹追踪、入侵检测、呼吸检测等感知业务)。
如图4所示，第四序列长度M0对应感知测量总持续时长，第二序列0，1，…为根据相干处理时间窗口0，1，…对第四序列进行截取得到的。
需要注意的是，上述二维感知信号的生成，还可以是根据第三序列和第四序列直接生成整体二维信号(生成方式如前面实施例所述，具体与基于第一序列和第二序列生成二维感知信号同理)，然后根据感知信号频域资源信息和时域资源信息对整体二维信号进行频域和时域截取获得二维感知信号。
