下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的DD 域的控制信道资源的指示方法进行详细地说明。
图2是本申请实施例提供的DD域的控制信道资源的指示方法的流程示意图之一，如图2所示，该方法可以包括步骤201-202；其中：
步骤201、第一通信设备获取DD域的控制资源集合(Control resource set，CORESET)配置信息。
步骤202、第一通信设备基于所述DD域的CORESET配置信息，检测DD域的控制信道。
需要说明的是，本申请实施例可应用于OTFS系统中，在OTFS系统中，发送侧的信号处理流程是首先从DD域变换至TF域，然后从TF域变换至时域(T域)，最后T域经过信道至接收侧；接收侧的信号处理流程是首先从T域变换至TF域，再从TF域变换至DD域，调制符号的判决在DD域。本申请可基于DD域的CORESET配置信息在DD域检测控制信道，这样可避免调制符号的判决需要依赖TF域所导致的载波间干扰(Inter Carrier Interference，ICI)。第一通信设备可以是接收设备，第二通信设备可以是发送设备，例如第一通信设备和第二通信设备可以是基于旁链路进行通信的设备。或者，第一通信设备可以包括上述所列举的终端11，第二通信设备可以包括上述所列举的网络侧设备12。
可选地，所述DD域的CORESET配置信息用于指示DD域的控制信道的资源映射规则，即DD域CORESET的定义，或者指示DD域的控制信息所在的资源范围。DD域的控制信道的最小资源单位为DD域资源元素(Delay-Doppler RE，DRE)。具体地，所述DD域的CORESET配置信息中包括以下至少一项：
1)映射模式，用于指示DD域的控制信道元素(delay-Doppler control channel element，DCCE)按照延迟维度和/或多普勒维度映射在DD域资源格上，以及所映射的资源块的大小。所述DCCE可以为DD域的控制信道的最小解调单位；一个DCCE中可以至少容纳一个基于最高调制与编码策略(Modulation and Coding Scheme，MCS)调制后的控制信息，例如，上行信 道状态(Channel Information，CI)或者下行CI。
实际中，所述DCCE可以包括m×n个DRE；所述m为延迟维度的DRE数量；所述n为多普勒维度的DRE数量。即所述DCCE的资源块大小的维度，可以用m×n表示。DCCE可以按照DCCE在CR内的资源相对位置进行编号。具体地，所述映射模式可以包括以下至少一项：
(a)第一模式，用于指示在DCCE仅按照延迟维度映射的情况下，m>1且n＝1；
(b)第二模式，用于指示在DCCE仅按照多普勒维度映射的情况下，m＝1且n>1；
(c)第三模式，用于指示在DCCE按照延迟维度和多普勒维度映射的情况下，m>1且n>1。
2)聚合等级(Aggregation level，AL)，用于指示DCCE在延迟维度和/或多普勒维度的聚合等级。
实际中，按照某个AL组合的一组CCE即构成一个物理下行链路控制信道(Physical Downlink Control Channel，PDCCH)候选(candidate)。多个PDCCH candidate组成的资源区域构成一个CORESET。具体地，所述AL可以包括以下至少一项：
(1)第一聚合模式用于指示DCCE仅按照延迟维度聚合，配置为kτ；
(2)第二聚合模式用于指示DCCE仅按照多普勒维度聚合，配置为kν；
(3)第三聚合模式用于指示DCCE按照延迟维度和多普勒维度聚合，配置为
(kτ，kν)。
3)CORESET区域(CORESET region，CR)，包括DD域资源上连续的一组DRE。
具体地，CR的大小可以为M'×N'。其中，M'≤M，N'≤N，M用于指示DD域延迟维度的资源格的数量，N用于指示DD域多普勒维度的资源格的数量。每个CR中包括了多个PDCCH candidate，以及多个PDCCH candidate之 间的保护间隔。
4)重复等级(repeat level，RL)，用于指示DCCE在多普勒维度的复制映射次数。RL可以为一组整数，例如[1，2，4，8]。
可以理解的是，复制映射是指：对于从N到lN(l为大于1的整数)的调制符号向量的映射，可以通过复制(l-1)个调制符号，从而在变换后构造出具有稀疏特性的变换符号向量X2N，即X2N的每两个非零元素之间有l-1个零点；例如，X2N＝[X1,0,..,0,X2,0,..,0,…,XN,0,..,0]。
5)单独标识(singleton flag，SF)，用于指示DD域的控制信道与DD域的数据信道是否复用传输；实际中，所述SF可以占用1比特(bit)。
6)导频在DD域资源格中的位置。
7)DD域的控制信道在DD域资源格的位置。
8)DD域的CORESET突发(burst)包括的CORESET数量。具体地，按照某RL组合的一组CORESET即构成一个CORESET burst。
本申请实施例DD域的CORESET配置信息中包括的映射模式、聚合等级、CR、重复等级、单独标识、导频在DD域资源格中的位置、DD域的控制信道在DD域资源格的位置、或者DD域的CORESET突发包括的CORESET数量等参数，便于终端基于这些参数的指示检测DD域的控制信道。
本申请实施例定义的DCCE，作为DD域的控制信道的最小解调单位，可以容纳一个完整的DCI，对应NR中的控制信道单元(control channel element，CCE)的概念。由于OTFS的解调方式以时隙为单位，而OFDM以符号为单位，因此DCCE在资源映射模式(pattern)上具有更大自由度，不需要局限于一个OFDM符号进行一维映射；其次，AL也可以以二维方式进行，用来支持对下行控制信息(Downlink Control Information，DCI)进行速率匹配(rate matching)。
本申请实施例提供的DD域的控制信道资源的指示方法中，第一通信设备获取DD域的CORESET配置信息，然后第一通信设备基于DD域的CORESET配置信息，检测DD域的控制信道，实现利用DD域资源承载OTFS 系统控制信息的DD域的控制信道资源指示；无需将QAM先映射在TF域，再从TF域变换至DD域，因为在OTFS系统中，发送侧的信号处理流程是首先从DD域变换至TF域，然后从TF域变换至时域(T域)，最后T域经过信道至接收侧；接收侧的信号处理流程是首先从T域变换至TF域，再从TF域变换至DD域，调制符号的判决在DD域；若将QAM先映射在TF域，再从TF域变换至DD域，那么发送侧的信号处理流程是首先从TF域变换至DD域，然后从DD域变换至TF域，再从TF域变换至T域，T域经过信道至接收侧；接收侧的信号处理流程是首先从T域变换至TF域，再从TF域变换至DD域，最后从DD域变换至TF域，调制符号的判决还是在TF域。可知在将QAM先映射在TF域，再从TF域变换至DD域中，调制符号的判决需要依赖TF域，而本申请提供的DD域的控制信道资源的指示方法中，调制符号的判决在DD域。
可选地，所述第一通信设备确定DD域的CORESET配置信息的实现方式可以包括：所述第一通信设备基于协议预定义或高层配置，确定所述DD域的CORESET配置信息。
实际中，所述DD域的CORESET配置信息可以由第二通信设备发送至第一通信设备。具体地，第一通信设备接收第二通信设备发送的DD域的CORESET配置信息的实现方式可以包括以下至少一项：
1)所述第一通信设备接收所述第二通信设备发送的广播消息；所述广播消息中包括所述DD域的CORESET配置信息；
2)所述第一通信设备接收所述第二通信设备在DD域目标信道上发送的所述DD域的CORESET配置信息。
具体地，所述DD域目标信道为用于承载所述DD域的CORESET配置信息的专用信道，例如物理控制格式指示信道(Physical control format indicator channel，PCFICH)。通过配置专用信道指示DD域的CORESET配置信息。
所述DD域目标信道的资源位置可以由协议预定义。所述DD域目标信道的资源位置可以预留在DD域的资源上，所述DD域目标信道的资源位置 位于CR外且与CR正交。可选地，所述DD域目标信道的资源位置可以由以下至少一项参数确定：CR位置、系统帧号、时域位置(例如，子帧，时隙等)、时域周期、系统带宽、传输格式(例如，OTFS或OFDM)、编码、DD域的DRE的位置(例如，M的值、N的值)、时频(TF)域的频域位置(例如，子载波/资源单元RE)和小区标识(ID)。其中，编码可以为正交相移键控(Quadrature Phase Shift Keying，QPSK)。
3)所述第一通信设备接收所述第二通信设备在DD域目标资源上发送的所述DD域的CORESET配置信息。
具体地，所述DD域目标资源为用于发送所述DD域的CORESET配置信息的资源，所述DD域目标资源的位置可以位于CR内。实际中，可以在CR之内预留一些DCCE资源，预留的DCCE资源用来放置特殊控制信令，例如特定DCI格式，所述特定DCI格式的作用是指示当前帧或后续一个或多个帧中控制信道的配置信息(例如，DD域内的资源位置，或DCCE的配置等)。
放置公共DCI资源位置位于CR内。可选地，所述DD域目标资源的位置可以由以下至少一项参数确定：系统帧号、系统带宽、DD域的DRE的位置(例如，M的值、N的值)、小区ID和用户设备特定(UE specific)的ID。UE specific ID例如小区无线网络临时标识符(Cell Radio Network Temporary Identifier，C-RNTI)。
或者，公共DCI资源位置也可以位于特定编号的DCCE中。实际中，该特定编号由广播消息指示。
可选地，所述第一通信设备除了接收第二通信设备发送的DD域的CORESET配置信息，或者确定DD域的CORESET配置信息之外，所述第一通信设备还可以接收所述第二通信设备发送的DD域搜索空间(Search Space，SS)配置信息；其中，所述DD域的SS配置信息用于指示所述终端搜索DD域的控制信息的资源范围。例如，所述DD域的SS配置信息可以包括：DD域SS对应的CORESET、及资源搜索范围。
本申请实施例通过定义UE在DD域CORESET进行资源搜索的流程。对于特定UE，CORESET仅给定了控制消息所在的资源范围，考虑到DD域的SS配置信息可以指示UE搜索DD域的控制信息的资源范围，通过根据CORESET配置和SS配置消息，进行资源搜索。基于这种方案，当多UE复用相同CORESET时，利用单独的无线资源控制(Radio Resource Control，RRC)信令为各个UE进行SS配置，能够减少搜索复杂度。
这里对第二通信设备发送DD域的CORESET配置信息和DD域的SS配置信息的实现方式进行说明。第二通信设备发送DD域的CORESET配置信息和DD域的SS配置信息的实现方式包括以下至少一项：
1)DD域的CORESET配置信息携带于广播消息中，且DD域的SS配置信息携带于专用无线资源控制(dedicated RRC)消息中。
具体地，CORESET配置信息(可记为CORESET_config)由广播消息发送，小区内所有UE接收相同的CORESET_config。所述广播消息包括主信息块(Master Information Block，MIB)或系统信息块(System Information Block，SIB)，所述广播消息可以在物理广播信道(Physical Broadcast Channel，PBCH)或者物理下行共享信道(Physical Downlink Shared Channel，PDSCH)中发送。
DD域的SS配置信息(可记为SS_config)由dedicated RRC消息发送，所述RRC消息在PDSCH中发送。不同的UE接收不同的SS_config，从而在各自分配的资源范围内进行控制消息的检测。
2)DD域的CORESET配置信息和DD域的SS配置信息均携带于dedicated RRC消息中。
具体地，CORESET_config和SS_config均由dedicated RRC消息发送，所述RRC消息在PDSCH中发送。不同的UE接收专属的CORESET_config和SS_config组合，从而在各自分配的资源范围内进行控制消息的检测。
3)DD域的CORESET配置信息和DD域的SS配置信息均携带于广播消息中。
具体地，CORESET_config和SS_config均由广播消息发送，小区内所有 UE接收相同的CORESET_config。不同的UE接收相同的CORESET_config和SS_config组合，从而在相同的资源范围内进行各自控制消息的检测。所述广播消息包括MIB或SIB，所述广播消息可以在PBCH或者PDSCH中发送。
在此基础上，所述第一通信设备基于所述DD域的CORESET配置信息，检测DD域的控制信道的实现方式可以包括：所述第一通信设备基于所述DD域的CORESET配置信息和所述DD域的SS配置信息，进行资源搜索，检测DD域的控制信道。

3)第三搜索范围，包括搜索的延迟起始位置k0和延迟终止位置kend；其中，k0、kend可以包括以下至少一项：
(a)DCCE在DD域资源格上的delay维度坐标；
(b)DCCE相对于DD域资源格上某delay维度参考位置的偏移量。
4)第四搜索范围，包括搜索的DCCE编号索引。
本申请实施例中，DD域的控制信道与DD域的数据信道的传输方式包括以下任一种：
传输方式1、DD域的控制信道与DD域的数据信道复用在同一个DD域 资源格上。
具体地，情况1提及的复用方式具有如下特点：导频位置由广播信令或者RRC信令配置；导频位置既可以位于DD域的控制信道中，也可以位于DD域的数据信道中。接收设备解调时，需要将DD域的控制信道(即CORESET)和数据信道的信息同时解调，之后对位于CORESET中的解调符号进行译码得到控制消息。
可选地，在所述DD域的控制信道与DD域的数据信道复用在同一个DD域资源格上的情况下，所述DD域的CORESET配置信息(通过广播信令或者RRC信令携带)中可以包括以下任一项：

(2)第二位置信息，用于指示导频在所述DD域资源格的位置。第一位置信息即导频开始资源位置相对于整个DD域资源格的offset(delay和Doppler两个维度)。
传输方式2、DD域的控制信道独自使用一个DD域资源格。
具体地，情况2提及的复用方式具有如下特点：一方面，控制信道单独调制解调，避免了与数据信道复用时的额外解调开销和时延；另一方面，根据按需进行CORESET的DD域复制传输，也即DD域的CORESET burst，能够增大M和N，进而增加信号的延迟分辨率和多普勒分辨率，提升控制信道的可靠性。
可选地，在所述DD域的控制信道独自使用一个DD域资源格的情况下，所述DD域的CORESET配置信息中包括以下至少一项：
(1)第一指示信息，用于指示所述DD域的控制信道是否单独调制；例如，可以使用1bit指示控制信道是否单独调制。
