技术领域
本发明涉及通信技术领域，特别涉及一种资源确定、配置方法及通信设备。
背景技术
在复杂的电磁波传输环境中，由于存在大量的散射、反射和折射面，造成了无线信号经不同路径到达接收天线的时刻不同，即传输的多径效应。当发送信号的前后符号经过不同路径同时抵达时，或者说，当后一个符号在前一个符号的时延扩展内到达时，即产生了符号间干扰(inter symbol interference，ISI)。类似的，在频域上，由于收发端相对速度引起的多普勒效应，信号所在的各个子载波会产生频率上不同程度的偏移，造成原本可能正交的子载波产生重叠，即产生了载波间干扰(inter carrier interference，ICI)。现有协议中使用的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)多载波系统，通过添加循环前缀(cyclic prefix，CP)的设计，抗ISI的性能较好。但是OFDM的弱点是子载波间隔的大小有限，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。通过同时在收发端把业务数据和导频映射到延迟多普勒域处理，避免在高速场景下的ICI和ISI。
此外，在OFDM系统中直流载波噪声也是一个重要问题。LTE和NR通 信系统中的信号发射机和接收机一般采用零中频方案或一次变频方案实现基带和射频之间的变换。零中频和一次变频方案存在本振泄漏问题，会在发射和接收时在信号载频处产生一个较大的直流子载波噪声，导致该频率上信噪比非常差，该子载波称为直流(direct current，DC)子载波。
长期演进(Long Term Evolution，LTE)中，下行OFDM留空DC子载波，上行SC-FDMA采用频偏7.5KHz的方案。目前，5G新空口(New Radio，NR)中由于其使用的带宽的宽度和频域位置不固定(主要是因为使用了部分带宽(Bandwidth Part，BWP)和载波聚合(Carrier Aggregation，CA)，其直流子载波在频段内的位置也不固定，因此，在留空DC子载波时，使用的方法复杂度较高，信令开销也较大。

在本申请实施例中，还可确定导频栅格、导频栅格的保护间隔和数据栅格。导频可以是任意导频，如脉冲导频、序列导频。除上述数据和导频外，若有其他类型的信息传输，可以占用数据栅格和导频栅格，不能占用0多普勒留空栅格和0多普勒留空栅格的保护间隔或者不能占用直流专用留空栅格。
本申请实施例的资源确定方法，确定第一资源栅格，所述第一资源栅格为与直流子载波相关的延迟多普勒域资源栅格，该第一资源栅格包括直流专用留空栅格，或者，所述第一资源栅格包括0多普勒留空栅格和所述0多普勒留空栅格的保护间隔。由于直流子载波噪声在延迟多普勒域的响应位置是固定的，因此，可通过上述第一资源栅格在延迟多普勒域进行资源留空或估计直流子载波噪声在延迟多普勒域的响应来抑制直流子载波噪声对数据造成的影响，可以在保证业务可靠性的前提下，减少信令开销和处理复杂度。
可选地，所述直流专用留空栅格或所述0多普勒留空栅格包括多普勒为0的所有栅格。

其中，所述抖动至少包括信号的幅度抖动。在所述直流专用留空栅格或所述0多普勒留空栅格包括多普勒为0的部分栅格的情况下，留空栅格数与多普勒为0的不同延迟栅格上信号的抖动有关，抖动大时需要的留空栅格多，抖动小时需要的留空栅格少。留空栅格数需要随着影响该抖动的信道条件(如信噪比)自适应变化。该模式下，只需每隔Q个正交时频空域(Orthogonal Time Frequency Space，OTFS)网格留空一部分多普勒为0的栅格，并估计DC子载波噪声响应。该估计值不仅可以用于当前的OTFS网格，还可用于后续Q-1个OTFS网格，后续的这Q-1个OTFS网格中多普勒为0的栅格无需留空。
可选地，所述直流专用留空栅格或所述0多普勒留空栅格与导频栅格的保护间隔共用相同的栅格。
这里，为了降低保护间隔的开销，导频栅格的保护间隔与留空栅格的保护间隔可以共用。
假设导频栅格的保护间隔在多普勒域需要留空导频周围的正负向各K P个多普勒，则为了共用保护间隔，导频的放置位置与0多普勒留空栅格的保护间隔的边界或直流专用留空栅格的边界之间的距离在多普勒域上不超过K P个多普勒。

可选地，本申请实施例的资源确定方法，还包括：

可选地，本申请实施例的资源确定方法，还包括：

这里，在所述直流专用留空栅格或所述0多普勒留空栅格包括多普勒为0的部分栅格的方案中，接收端利用留空的栅格估计DC子载波直流噪声在延迟多普勒域的响应。估计出该响应后，从多普勒为0的数据或导频栅格上减掉这个响应，再进行数据检测或基于导频的信道估计，保护间隔上的信息正常参与数据的检测或进行基于导频的信道估计。
需要说明的是，本申请实施例中，资源确定方法适用于单用户和多用户传输。
下面结合具体的实施例对本申请的资源确定方法进行说明。
实施例一：多普勒为0的所有栅格留空方案。
考虑一个由M×N维度的OTFS延迟多普勒网格，其中，M表示延迟域的格点数，N表示多普勒域的格点数。最大多普勒为K MaxDopp，最大延迟为 L MaxDelay。导频保护间隔需要留空导频周围的正负向各K p个多普勒和正负向各L p个延迟。
以五类栅格方案(0多普勒留空栅格、所述0多普勒留空栅格的保护间隔、导频栅格、导频栅格的保护间隔和数据栅格)为例，如图3所示，发送时，多普勒为0的所有延迟对应的栅格留空。除了多普勒为0的栅格，还要在多普勒域设置保护间隔，避免数据和/或导频经历延迟多普勒域信道后落到多普勒为0的栅格上。该多普勒域设置保护间隔需占K 0个多普勒，其中，K 0＞K MaxDopp。因此，额外的资源开销至少为(K 0+1)×M个栅格。
四类栅格方案(直流专用留空栅格、导频栅格、导频栅格的保护间隔和数据栅格)中，将上述五类栅格方案中的0多普勒留空栅格和留空栅格的保护间隔统称为直流专用留空栅格。
可由网络侧通过信令(RRC，PDCCH，MAC CE，SIB等)通知终端上述留空或保护栅格的图样的索引；其中，每种图样对应一种索引，每种索引的图样是协议定义的。也可通过协议规定上述留空或保护栅格，且上述留空或保护栅格的图样与OTFS的参数关联，每种参数对应一种留空或保护栅格的图样，即终端只要知道了OTFS的参数，就会根据协议确定上述留空或保护栅格的图样。
对于发送端设备，导频及其保护间隔，数据均需放在上述0多普勒留空栅格和留空栅格栅格区域外，且在导频周围(多普勒域和延迟域)留有足够的保护间隔避免数据与导频之间的互干扰。对于接收端设备，在多普勒非0的栅格上进行数据检测或进行基于导频的信道估计，多普勒为0的所有栅格按0处理，保护间隔上的信息正常参与数据的检测或基于导频的信道估计。
为了降低保护间隔的开销，导频的保护间隔与留空栅格的保护间隔(五类栅格方案)或直流专用留空栅格(四类栅格方案)的一部分可以共用。如图4所示，为五类栅格方案中导频保护间隔与留空栅格保护间隔共用的情况。此导频的放置位置与留空栅格保护间隔(五类栅格方案)的边界或直流专用留空栅格(四类栅格方案)的边界之间的距离在多普勒域上不超过K P个多普 勒。若超过这个距离，就没有可以共用的保护间隔了。
多用户时正常在网格上划分多个用户的资源区域传输，不得占用多普勒为0的留空栅格和留空栅格的保护间隔。
该方案操作简单，相比于传统的在时频域留空的优势：在NR OFDM中，DC的位置是不确定的，若想通过留空DC子载波，需要一定的信令交互告知收发双方具体的留空位置。但是，OTFS中，DC的响应一直都是在多普勒为零处。所以，留空多普勒为零的栅格不会带来额外信令开销。
实施例二：多普勒为0的部分栅格留空的方案。
考虑一个由M×N维度的OTFS延迟多普勒网格，其中，M表示延迟域的格点数，N表示多普勒域的格点数。最大多普勒为K MaxDopp，最大延迟为L MaxDelay。导频保护间隔需要留空导频周围的正负向各K p个多普勒和正负向各L p个延迟。
以五类栅格方案(0多普勒留空栅格、所述0多普勒留空栅格的保护间隔、导频栅格、导频栅格的保护间隔和数据栅格)为例，发送时，多普勒为0的部分栅格留空(留空的格点数记为Γ)，其他位置仍放数据或导频。接收端，利用留空的Γ个栅格估计DC子载波直流噪声在延迟多普勒域的响应。估计出该响应后，从多普勒为0的数据或导频栅格上减掉这个响应，再做数据的检测或基于导频的信道估计，留空的Γ个栅格处按0处理，保护间隔上的信息正常参与数据的检测或基于导频的信道估计。
四类栅格方案(直流专用留空栅格、导频栅格、导频栅格的保护间隔和数据栅格)中，将上述五类栅格方案中的0多普勒留空栅格和留空栅格的保护间隔统称为直流专用留空栅格。
可由网络侧通过信令(RRC，PDCCH，MAC CE，SIB等)通知终端上述留空或保护栅格的图样的索引；其中，每种图样对应一种索引，每种索引的图样是协议定义的。也可通过协议规定上述留空或保护栅格，且上述留空或保护栅格的图样与OTFS的参数关联，每种参数对应一种留空或保护栅格的图样，即终端只要知道了OTFS的参数，就会根据协议确定上述留空或保 护栅格的图样。
留空栅格数与多普勒为0的不同延迟栅格上的抖动有关，抖动大时需要的留空栅格多，抖动小时需要的留空栅格少。该抖动主要与噪声大小(信噪比)有关。噪声越大(信噪比越低)抖动越大。这是因为，每个多普勒为0格点上都可以估计DC子载波直流噪声在延迟多普勒域的响应。但在接收端多普勒为0的格点上，除了DC子载波直流噪声在延迟多普勒域的响应外，还包含着传输信道中噪声的影响。当SNR较高，传输信道的噪声较小时，使用较小的Γ就可以较好的估计出DC子载波直流噪声在延迟多普勒域的响应。但是，当SNR较低，传输信道的噪声较大时，需要较大的Γ(进行平均或合并)才能较好的估计出DC子载波直流噪声在延迟多普勒域的响应。因此，多普勒为0处留空的格点数Γ要随SNR自适应变化。
在多普勒为0处留空的栅格周围(多普勒域和延迟域)需要进一步留空一部分栅格作为保护间隔，避免数据和导频经历信道后落在多普勒为0处留空的栅格上。若留空的位置在延迟域始于0(如图5所示)，多普勒域保护间隔K 0需大于K MaxDopp个多普勒，在延迟域不需要保护间隔(因为数据只会产生正向延迟)。此时总开销为(K 0+1)×Γ个格点。若留空的位置在延迟域始于非0处(如图6所示)，多普勒域保护间隔K 0需大于K MaxDopp个多普勒，延迟域保护间隔L 0需大于L MaxDelay个延迟(因为数据只会产生正向延迟)。此时总开销为(K 0+1)×(L 0+Γ)个格点。
为了降低保护间隔的开销，导频的保护间隔与留空栅格的保护间隔(五类栅格方案)或直流专用留空栅格(四类栅格方案)的一部分可以共用。如图7所示，描述了五类栅格方案中导频保护间隔与留空栅格保护间隔共用的情况。此导频的放置位置与留空栅格保护间隔(五类栅格方案)的边界或直流专用留空栅格(四类栅格方案)的边界之间的距离在多普勒域上不超过K P个多普勒。若超过这个距离，就没有可以共用的保护间隔了。

个OTFS栅格，需在多普勒为0处配置一次留空(和 对应的保护间隔)，估计DC子载波直流在延迟多普勒域的响应(该估计值可用于连续的Q个OTFS栅格)，其中T V表示在时间频率域DC直流持续不变的符号数(OFDM符号数)，

表示下取整。原则上不需要为每个M×N维度的OTFS延迟多普勒栅格都配置留空和保护间隔。因为DC子载波直流相对来讲较为稳定，随着时间变化较慢。同时，每个多普勒为0格点上都包含了时间频率域N个OFDM符号的DC子载波直流信息，在延迟多普勒域已经被平均了，所以在延迟多普勒域的变化更加缓慢。
多用户时仍然使用上述留空和保护间隔。上行时，基站估计出的是所有终端的DC子载波在延迟多普勒域的响应。在多普勒为0的其他数据栅格无论是分配给哪个终端，都是先从接收到的数据或导频上减去上述“所有终端的DC子载波在延迟多普勒域的响应”的估计值再做检测或信道估计。下行时，终端估计自己的DC子载波在延迟多普勒域的响应。综上，多用户时不需要增加额外的开销。
