资源大小的确定方法、终端及网络侧设备
相关申请的交叉引用
本申请主张在2022年10月21日在中国提交的申请号为202211296942.X的中国专利的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种资源大小的确定方法、终端及网络侧设备。
背景技术
正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)多载波系统的抗符号间干扰(Inter Symbol Interference，ISI)性能较好，但是，OFDM的弱点是子载波间隔大小有限，因此，在应对高速移动场景下(如高铁)，由于收发端之间较大的相对速度带来的较大多普勒频移，破坏了OFDM子载波之间的正交性，使子载波间产生严重的载波间干扰(Inter Carrier Interference，ICI)。
正交时频空域(Orthogonal Time Frequency Space，OTFS)技术的提出则致力于解决以上OFDM系统中的问题。OTFS技术定义了延迟多普勒域和时频域之间的变换，通过在收发端把通信数据和导频映射到延迟多普勒域处理，减少了数据样点间的耦合干扰，获得了额外的分集增益和信道估计增益。
OTFS技术一大显著特点是在延迟多普勒域独特的导频设计，通过导频可以实现系统的感知功能；同时，通过通信数据可以实现系统的通信功能，然而，由于通信数据和导频是共同映射在延迟多普勒域资源上，无法实现感知指标和通信指标之间的权衡，例如，在满足感知指标时无法满足通信指标，或者，在满足通信指标时无法满足感知指标。

为详细说明本申请实施例提供的资源大小的确定方法，以下将结合几个具体的实施例进行说明。
本申请实施例设计了导频信号发送和接收处理机制，定义了相应的信令内容和信令交互流程，可以保障延迟多普勒域的感知导频在通感一体系统中可以顺利工作，以下将首先对本申请实施例的实施原理进行推导说明。
(一)、基于无循环前缀(Cyclic Prefix，CP)/循环后缀(Cyclic Suffix，CS)的延迟多普勒域导频的设计
假设发送符号矩阵为采用的导频块大小为NP×MP,NP<N,MP<M，并且不存在延迟及多普勒域上的循环前缀或者循环后缀。
由于本申请技术方案中，导频符号功率与数据符号功率相等，设置为则导频块的总功率为可以看出，分配于导频块的总功率仅取决于导频块的大小。
对于感知功能来说，其感知性能主要取决于接收信号的信干噪比(SINR)。对感知系统来说，关心的是其经历LOS径的导频部分的回波。假设回波具有的L条多径，则其延迟多普勒域上的回波接收模型为：
公式(1)中的第一项为信号(Signal)，第二项为干扰项(Interference)，第三项为噪声(noise)。
其中，(hi,τi,vi)定义了第i条径的信道增益，延迟和多普勒，分别是物理参数τi,vi量化在延迟多普勒域二维资源格上的量化。在雷达感知中，通常认为h0>hi,i≠0。干扰项包含了所有数据部分的回波，以及经历NLOS径的导频回波，环境杂波和热噪声统一定义为噪声wN，且
注意到，严格意义上来说，和分别为S和D在延迟维度和多普勒维度的循环位移版本，并且具有逐元素的相位偏移。由于这种固定相移并不影响感知检测，并且在感知检测得到CSI后可以很容易的补偿掉，因此为简略表示，在建模分析时可以忽略相移。
用和分别表示延迟多普勒域的导频符号矩阵和数据符号矩阵。其中所述导频块位于导频符号矩阵中，大小为NP×MP，导频符号矩阵除导频块以外的符号值均为零。数据符号矩阵中，对应导频符号矩阵中的导频块位置的符号值均为零，其余位置放置发送数据的调制符号。X为发送符号矩阵，且满足S+D＝X。如图3所示。
接收侧使用Y与S[a,b]进行线性相关运算，根据所得到的相关信号累积功率来判断LOS径回波在延迟多普勒平面上的位置。对于感知来说，通常假设目标的反射路径为LOS径。同时，在可分辨的条件下，各目标的反射径至少不同的延迟或多普勒其中之一，即τj≠τjorvi≠vj,i≠j。
假设某一移动目标与发送端的通信感知一体化(ISAC)机的距离和速度分别对应(τ0,v0)。利用S的循环位移S[a,b]在感知接受侧进行线性相关检测。当时，有：
其中通过数值验证可知 通过数值验证可知且当或者 时，ψ0i＝0。σ为噪声随机变量的标准差，而其方差σ2即为延迟多普勒域上的噪声功率密度，即每个延迟多普勒域资源格点上的噪声功率。通过数值验证可知ξ＜＜MPNP，如图4所示，图4是导频与随机噪声内积绝对值的CCDF曲线，10000次循环，MP＝63，NP＝63。
而当即在接收侧S[a,b]并未与LOS径接收信号匹配(重合)时，有：
对基于阈值的LOS径判定来说，希望与的大小差距越大越好，这样才会减少误判的概率。注意到在上述内积公式中，唯一可控的参数是MPNP。由于对感知场景假设h0>hj，相对MPNP来说是单调递增的。换言 之，增大导频块大小，会增加LOS径线性相关峰值与其他反射径之间的差距，从而减少感知目标检测的误检率。
由上述分析可知，采用线性相关检测时，对于LOS径而言，定义其感知信号的检测SINR为：
考虑到S+D＝X，MPNP→MN时ρ0i→0，有：
由公式(5)可以看出，增大MPNP具有减少数据对导频的干扰的作用。对感知而言，最优化选择是全部放置导频，即MPNP→MN。但是导频符号的增加会减少通信符号(考虑吞吐需求，MCS)的可用资源，因此需要取得感知导频性能与通信性能之间的权衡。
公式(5)分母的第一项中，为LOS径与所有干扰径的信道增益比值，而通过导频块设计，利用内积之后的系数因子将干扰径的信号功率显著抑制。公式(5)分母的第二项中，环境噪声的影响则通过由系数因子进行了抑制。
事实上，通过所述的导频设计与线性相关检测结合，可以把所述导频块看成是一个预编码矩阵，其作用是将MP×NP大小的资源上的信号功率投射到所述预编码矩阵定义的信号子空间上，而回波干扰和环境噪声的大部分功率则被投射到了所述信号子空间以外，从而体现了显著的干扰和噪声抑制的效果。
评估单链路的通信性能通常有两个维度：误码率和吞吐量。在调制编码参数确定的情况下，误码率主要信道估计精度的影响，而吞吐量主要受误码率和发送的信息比特数影响。在延迟多普勒域对于通信信号的信道估计，也可以使用与感知类似的信道估计方法。
对于单站感知，通常认为感知信道为通信信道的双程，其时延和多普勒均为通信信道的两倍，因此通信信道的信道质量好于感知信道；对于多站感知，实际上感知接收机可以看做是一个仅做信道估计，无需解调译码的通信接收机。因此如果发送信号满足感知的信道估计需求，则我们可以假定也满足通信的信道估计精度需求。
由上述分析可知，通信业务的需求主要受限于吞吐量需求。即本实施例中延迟多普勒域所分配给的通信数据的资源大小，以及(次要的)MCS参数。
(二)、基于有CP/CS的延迟多普勒域导频的设计
在其他的设定与以上的(一)中的设定相同时，采用导频块SCP添加了延迟域的大小为的循环前缀，以及多普勒域上的大小分别为和的循环前缀和循环后缀，总大小仍为NP×MP，并且。假设回波具有的L条多径，则其延迟多普勒域上的回波接收模型为：
公式(6)中的第一项为信号(Signal)，第二项为干扰项(Interference)，第三项为噪声(noise)。其中SCP与S的关系如图5所示。
导频序列接收侧使用Y与(非SCP[a,b])进行线性相关运算，根据所得到的相关信号累积功率来判断LOS径回波在延迟多普勒平面上的位置。S[a,b]中仅包含去除了CP/CS的导频块，大小为其中由于循环前后缀根据最大时延和最大多普勒设定，因此S[a,b]中非零元素部分始终被限制在SCP内。因此不存在S[a,b]与数据D之间的内积项。
假设某一移动目标与ISAC机的距离和速度分别对应(τ0,v0)。利用S的循环位移S[a,b]在感知接受侧进行线性相关检测。当a＝τ0,b＝v0时，有：
其中而当a＝τj,b＝vj，即在接收侧S[a,b]并未与LOS径接收信号匹配(重合)时，有：
同时，由上面公式可知，对于LOS径而言，其感知信号的SINR可以定义为：
可见如果以CP/CS的开销为代价，则感知SINR中完全避免了数据D的干扰影响，而噪声影响也同样得到了抑制。
以下实施例一介绍了适用于感知任务优先场景的导频块配置流程；实施例二介绍了适用于通信任务优先场景的导频块配置流程。
实施例一
实施例一适用于感知任务优先场景。本实施例主要解决了ISAC系统中使用相同的通信感知信号，如何达成通信和感知指标的兼顾统一的问题，该实施例包括如下步骤。
步骤一：
通信感知一体化(ISAC)发送机根据系统的感知分辨率指标确定M和N的大小，即通信感知帧(简称通感帧)大小。其中，M由延迟分辨率确定，N由多普勒分辨率确定。
为减少开销，协议可以预配置一组帧结构组合，以带索引的列表形式给出。如表格1所示。
表格1帧结构配置表
对于通信对端，ISAC发送机将帧结构配置的具体值，或者其索引，通过如下方式指示给通信接收侧：1)同步信号(隐式)指示；2)PBCH中的显式指示；3)PDCCH中的DCI显式指示；4)SIB中显式指示；5)RRC中显式指示。
对于感知对端，单站感知无需指示。多站感知则需要ISAC发送机将帧结构配置的具体值，或者其索引，通过如下方式指示给感知接收侧：1)通过基站或专属SCN配置转发给感知对端。通过ISAC发送机与感知对端的通信链路(如有)发送。并可以沿用上一段1)-5)的方式来指示。
步骤二：
ISAC发送机根据系统的感知误差精度指标确定MP和NP的大小，即所用感知导频(或称导频块)大小。感知误差精度由感知SINR确定，则可以根据前述推导的各参数之间的关系，估算所需的MP和NP。
当导频有CP/CS时，MP和NP可以由公式(9)直接计算确定。而σ2可以由成熟的噪声估计方法确定。公式(9)中的变量可以根据协议中，各典型感知信道的场景建模来估算其下界。
其中，当导频无CP/CS时，MP和NP的关系满足公式(4)。由于公式(4)所含的ρ0i是一个多因子的随机变量，其取值如下因素有关：1)与MP和NP的取值；2)导频块的生成序列以及3)QAM调制阶数均相关，难以得到解析形式。为此，可以预先由蒙特卡洛方法，遍历多种ρ0i，σ2，以及确定一组感知SINR与MP和NP的对应关系，并且在协议中以索引列表形式体现，如表格2所示。
表格2导频块配置表
对于通信对端，ISAC发送机将导频块配置的具体值，或者其索引，通过如下方式指示给通信接收侧：1)同步信号(隐式)指示；2)PBCH中的显式指示；3)PDCCH中的DCI显式指示；4)SIB中显式指示；5)RRC中显式指示。
对于感知对端，单站感知无需指示。多站感知则需要ISAC发送机将导频块配置的具体值，或者其索引，通过如下方式指示给感知接收侧：1)通过基站或专属SCN配置转发 给感知对端。通过ISAC发送机与感知对端的通信链路(如有)发送。并可以沿用上一段1)-5)的方式来指示。
步骤三：
通信接收侧根据ISAC发送机的配置，进行通信数据的解调译码。并且根据ISAC发送机指示的目标误码率和/或目标吞吐量判断是否需要调整配置。该目标误码率和/或目标吞吐量可以是在步骤一中指示。
情况1：仅根据目标误码率判断
假设接收侧录得的实际误码率为Et。根据实际误码率是否小于目标误码率，通信接收侧向ISAC发送机发送1bit的反馈指示消息。例如1表示Et≥El，0表示Et<El，l为当前使用的帧结构配置索引。
情况2：仅根据目标吞吐量判断
假设接收侧录得的实际吞吐为Tt。根据实际吞吐是否小于目标吞吐量，通信接收侧向ISAC发送机发送1bit的反馈指示消息。例如0表示Tt≥Tl，1表示Tt<Tl。
情况3：根据目标误码率和目标吞吐量判断
假设接收侧录得的实际误码率和吞吐分别为Et和Tt，根据Et和Tt与目标值的比较，由感知接收侧向ISAC发送机发送2bit的反馈指示消息。例如00表示Et<El，且Tt≥Tl，01表示Et≥El，且Tt<Tl，10表示Et＞El，且Tt≥Tl，11表示Et＞El，且Tt<Tl。
步骤四：
ISAC发送机根据通信接收机的反馈消息，调整配置。
情况1：仅根据目标误码率判断
如收到反馈指示消息为0，则继续使用当前配置。
如收到反馈指示消息为1，则增大MCS，从表格2中重选一组对应的配置。
情况2：仅根据目标吞吐量判断
如收到反馈指示消息为0，则继续使用当前配置。
如收到反馈指示消息为1，则减少MCS，从表格2中重选一组对应的配置。
情况3：根据目标误码率和目标吞吐量判断
如收到反馈指示消息为00，则继续使用当前配置。
如收到反馈指示消息为01，则增大MCS，从表格2中重选一组对应的配置。
如收到反馈指示消息为10，则减少MCS，从表格2中重选一组对应的配置。
如收到反馈指示消息为11，则增大传输资源即MN，从表格1中重选一组对应的配置。
对于通信对端，ISAC发送机将根据情况1～情况3中有关帧结构以及导频块重配置的具体值，或者其索引，通过如下方式指示给通信接收侧：1)同步信号(隐式)指示；2)PBCH中的显式指示；3)PDCCH中的DCI显式指示；4)SIB中显式指示；5)RRC中显式指示。
对于感知对端，单站感知无需指示。多站感知则需要ISAC发送机将帧结构以及导频块重配置的具体值，或者其索引，通过如下方式指示给通信接收侧：1)通过基站或专属SCN配置转发给感知对端。通过ISAC发送机与感知对端的通信链路(如有)发送。并可以沿用上一段1)-5)的方式来指示。
实施例二
实施例二主要应用于通信优先场景，该场景下，感知属于“尽力而为”，如果对感知性能要求苛刻，可以按照实施例一执行，该实施例包括如下步骤。
步骤一：
ISAC发送机根据所采用的信道估计的方法不同，可以使用实施例一步骤二的方法或其他方法确定MP和NP的大小，即所用导频块大小。
ISAC发送机根据系统的通信吞吐需求以及MP和NP的大小确定通信所需通感帧的大小，即M和N。事实上，对感知功能而言，此时M确定了延迟分辨率，而N确定了多普勒分辨率。为减少开销，协议可以预配置一组帧结构组合，以带索引的列表形式给出。我们同样可以使用表格3表示。
表格3帧结构与导频块配置表
对于通信对端，ISAC发送机将导频块配置的具体值，或者其索引，通过如下方式指示给通信接收侧：1)同步信号(隐式)指示；2)PBCH中的显式指示；3)PDCCH中的DCI显式指示；4)SIB中显式指示；5)RRC中显式指示。
对于感知对端，单站感知无需指示。多站感知则需要ISAC发送机将导频块配置的具体值，或者其索引，通过如下方式指示给感知接收侧：1)通过基站或专属SCN配置转发给感知对端。通过ISAC发送机与感知对端的通信链路(如有)发送。并可以沿用上一段1)-5)的方式来指示。
步骤二：
感知接收侧根据根据ISAC发送机的配置，进行感知目标检测，同时计算感知SINR。并且根据ISAC发送机指示的目标感知SINRZl判断是否需要调整配置。根据感知SINR是否小于目标SINR，感知接收侧向ISAC发送机发送1bit的反馈指示消息。例如0表示Zt≥Zl，1表示Zt<Zl，l为当前使用的配置索引。
步骤三：
ISAC发送机根据感知接收机的反馈消息，调整配置。
如收到反馈指示消息为0，则继续使用当前配置。
如收到反馈指示消息为1，则增大MP和NP，从表格3中重选一组对应的配置。
对于通信对端，ISAC发送机将根据帧结构以及导频块重配置的具体值，或者其索引，通过如下方式指示给通信接收侧：1)同步信号(隐式)指示；2)PBCH中的显式指示；3)PDCCH中的DCI显式指示；4)SIB中显式指示；5)RRC中显式指示。
对于感知对端，单站感知无需指示。多站感知则需要ISAC发送机将帧结构以及导频块重配置的具体值，或者其索引，通过如下方式指示给通信接收侧：1)通过基站或专属SCN配置转发给感知对端。通过ISAC发送机与感知对端的通信链路(如有)发送。并可以沿用上一段1)-5)的方式来指示。
实施例三
实施一和实施例二中，发送侧还可以指示接收侧以下信息：所用的Xp[n,m]，即感知导频的信息，所述感知导频的信息包括如下至少之一：1)所述感知导频的序列或序列索引，上述序列索引可以是位于预先定义的序列索引表中，该序列索引表包括多个感知导频的序列以及每个感知导频的序列的索引；2)所述感知导频的序列的生成参数或生成参数索引，上述生成参数索引可以是位于预先定义的生成参数索引表中，该生成参数索引表包括多个感知导频的序列的生成参数以及每个生成参数的索引。
上述信息可以由RRC直接指示，也可以由协议预配置/RRC指示一个配置表格，由DCI指示索引值。
