具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
为了充分利用传输资源，本发明提出了一种解调参考信号映射方法，以实现对信道等传输资源的充分利用。
该解调参考信号映射方法可以应用于任意存在对传输资源的场景中，继续以重传场景为例，为了增加覆盖，协议支持PUSCH通过重复传输来获得更大的接收SNR，其中R16提出了repetition typeB的重传方式，适用于调度的PUSCH和免授权调度的PUSCH。
具体的，基站发送一个上行授权或者一个免授权指示一个或多个名义PUSCH重复传输。终端在一个时隙中传输一个或多个实际PUSCH副本，或者在连续多个可用的时隙中传输两个或者多个实际PUSCH副本。终端在确定基于TypeB的PUSCH重复在每个名义PUSCH时域资源内的无效符号后，其余的符号可以认为是潜在有效符号。如果一个名义PUSCH在时隙内连续潜在有效符号的个数大于0，则可以映射为一个实际PUSCH副本，一个名义PUSCH副本的时域资源可包含一个或者多个实际PUSCH副本的时域资源。终端设备不发送单个符号的实际PUSCH副本，除非单个符号是基站指示的名义PUSCH的持续时间L。
即如图1所示，当一个实际PUSCH副本包含仅仅一个时域资源(图中以一个单元格表示一个时域资源，该时域资源也可以理解为重传场景中的符号单元)，则并不针对发送该实际PUSCH副本，导致该实际PUSCH副本对应的时域资源浪费，显然，若是能够将这一部分的时域资源利用起来，必然会对重传带来积极的影响，比如，会提高重传效率等。
下面结合具体的实施例，详细说明本发明实施例的解调参考信号映射方法，其中，该方法应用于终端设备上，该终端设备包括但不限于移动手机、可穿戴式终端设备等通信设备。
图2是根据本发明实施例提供的一种解调参考信号映射方法的流程图，其中，包括：
步骤201，确定与满足拆分条件的逻辑传输资源对应的多个实际传输资源。
其中，逻辑传输资源可以理解为根据协议定义的理论上可传输的传输资源，比如，在重传场景中的名义PUSCH时域资源可以为逻辑传输资源的一种可能的示例，而实际传输资源可以理解为根据实际传输环境可用于传输的传输资源，比如，在重传场景中的实际PUSCH时域资源可以为实际传输资源的一种可能的示例。
在执行执行过程中，当逻辑传输资源满足拆分条件时，会将逻辑传输资源进行拆分，因此，在本实施例中，确定与满足拆分条件的逻辑传输资源对应的多个实际传输资源，以便于基于实际传输资源进行信息的传输。
需要说明的是，在不同的应用场景中，上述拆分条件不同，确定与满足拆分条件的逻辑传输资源对应的多个实际传输资源的方式不同，示例说明如下：
示例一：
在本示例中，将跨时隙边界的逻辑传输资源在时隙边界两侧的传输资源，分别确定为一个实际传输资源。其中，本实施例中的逻辑传输资源在时域上划分为多个时隙，每个时隙包含固定个数的符号，因此，每个时隙通过固定个数的符号限定出与其他时隙的时隙边界，若是存在逻辑传输资源跨时隙，则直接将该逻辑传输资源位于时隙边界一侧的传输资源确定为一个实际传输资源，将该逻辑传输资源位于时隙边界另一侧的传输资源确定为另一个实际传输资源。
举例而言，如图3所示，预先设置每个时隙包括的符号个数是固定的，比如图3所示的，当传输资源包括S时隙和U时隙时，每个时隙包括14个符号，从而，导致时隙之间会存在时隙边界，划分出的逻辑传输资源Nominal#1跨时隙，1个符号在S时隙，2个符号在U时隙，因此，继续参照图3，可以将跨越时隙边界的逻辑传输资源在时隙边界确定成两个实际传输资源，即将S时隙的第14个符号(即符号13)确定为一个实际传输资源Actual#1，将U时隙的第1和第2(即符号0和1)个符号确定为一个实际传输资源Actual#2。
示例二：
在本示例中，将位于无效符号的两侧且属于同一个时隙的逻辑传输资源拆分成两个实际传输资源，若是存在逻辑传输资源中包括无效符号，则直接将该逻辑传输资源位于无效符号一侧的传输资源确定为一个实际传输资源，将该逻辑传输资源位于无效符号另一侧的传输资源确定为另一个实际传输资源。
其中，本实施例中的逻辑传输资源在时域上划分为多个时隙，每个时隙包含固定个数的符号，该符号可以理解为时隙的最小组成单位，在一些可能的示例中，该符号可以为正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，每个符号可能由于其传输性能可能是有效的也可能是无效的，在实际应用中，将可以承载当前用户发送数据的符号定义为有效符号，将不可以承载当前用户发送数据的符号定义为无效符号，由于无效传输符号无法承载用户当前发送的数据，因此，在本实施例 中，以无效符号为边界，在无效符号的两侧的属于同一个逻辑传输资源的传输资源确定为两个实际传输资源。
举例而言，如图4所示，预先设置多个逻辑传输资源即图中的Nominal#，其中，若是Nominal#2中的符号3是无效传输符号，则如图4所示，将Nominal#2中的符号2设置为一个实际传输资源Actual#3，将符号4确定为一个实际传输资源Actual#4。
示例三：
在本示例中，将时隙边界的两侧属于同一个逻辑传输资源的传输资源，确定为两个实际传输资源。其中，本实施例中的逻辑传输资源在时域上划分为多个时隙，每个时隙包含固定个数的符号，因此，每个时隙通过固定个数的符号限定出与其他时隙的时隙边界。并且，可以将跨越时隙边界的逻辑传输资源在时隙边界确定成两个实际传输资源。其中，本实施例中的逻辑传输资源在时域上划分为多个时隙，每个时隙包含固定个数的符号，每个符号可能由于其传输性能可能是有效的也可能是无效的，由于无效传输符号无法承载用户当前发送的数据，因此，在本实施例中，还以无效符号为边界，将位于无效符号的两侧且属于同一个逻辑传输资源拆分成两个实际传输资源。
举例而言，如图5所示，预先设置每个时隙包括的符号个数是固定的，比如图5所示的，当传输资源包括S时隙和U时隙时，每个时隙包括14个符号，从而，导致时隙之间存在时隙边界，划分出的逻辑传输资源Nominal#1跨时隙，1个符号在S时隙，2个符号在U时隙，因此，继续参照图5，可以将时隙边界两侧属于同一个逻辑传输资源的传输资源，在时隙边界确定成两个实际传输资源，即将S时隙的第14个符号确定为一个实际传输资源Actual#1，将U时隙的第1和第2(即符号0和1)个符号确定为一个实际传输资源Actual#2。在图5中，预先设置多个逻辑传输资源即图中的Nominal#，其中，若是Nominal#2中的符号3是无效传输资源，则如图5所示，将Nominal#2中的符号2设置为一个实际传输资源Actual#3，将符号4确定为一个实际传输资源Actual#4。
步骤202，将解调参考信号映射到至少一个实际传输资源中与拆分位置相邻的有效符号上。
其中，解调参考信号可以理解为用于引导传输资源中的信息被解调的引导信息，比如，解调参考信号的一种可能的示例为重传场景中的DMRS(DeModulation-Reference Signal,解调参考信号)，为了便于描述，本发明的所有实施例中，以DMRS作为解调参考信号示例说明。
在本实施例中，将解调参考信号映射到至少一个实际传输资源中，与拆分位置相邻的有效符号上，比如，以图5所示的场景为例，如图6所示，将DMRS映射到S时隙的第14个符号即符号13。
由此，通过在与拆分位置相邻的有效符号上映射解调参考信号，一方面，可以保证即使实际传输资源仅仅包含一个有效符号，也可以被映射到，避免了传输资源被浪费；另一方面，由于映射到与拆分位置相邻的有效信号，则可以保证一个映射至少可以被相邻的两个实际传输资源使用，进一步降低了资源的消耗。
综上，本发明实施例的解调参考信号映射方法，确定与满足拆分条件的逻辑传输资源对应的多个实际传输资源，进而，将解调参考信号映射到至少一个实际传输资源中与拆分位置相邻的有效符号上。由此，提高了对传输资源的利用率，为重传信息以提高覆盖质量等场景提供了技术支撑，并且降低了解调参考信号映射时的资源消耗。
在实际执行过程中，拆分位置即可包括时隙边界，也可以包括无效符号，也可以包括时隙边界和无效符号，因此，在本实施例中，实际传输资源具有多样性，因此，将解调参考信号映射到至少一个实际传输资源中与拆分位置相邻的有效符号上的方式也必然具有多样性，下面示例说明：
当拆分位置包括时隙边界时，将解调参考信号映射到至少一个实际传输资源中与拆分位置相邻的有效符号上的方式，至少具有如下的一种或多种：
示例一：
在本示例中，将解调参考信号映射到时隙边界前一个实际传输资源中的最后一个有效符号上，其中，时隙边界前一个实际传输资源包含多个有效符号。
即如图6所示，将DMRS映射到S时隙的第14个符号，由此，映射的DMRS既可以作为Actual#1 的解调参考信号，也可以作为Actual#2的解调参考信号，甚至可以作为Actual#3等后续实际传输资源的解调参考信号，由于解调参考信号相对于其他实际传输资源的时隙靠前，可以提高后续实际传输资源的解调效率。
示例二：
在本实施中，将解调参考信号映射到时隙边界前一个实际传输资源中的有效符号上，其中，时隙边界前一个实际传输资源包含一个有效符号，也即是说，本发明的实施例中，充分利用仅仅包含一个有效符号的传输资源。
以图7所示的场景为例，若是Nominal#1中的符号13是有效传输符号，Nominal#1中的符号13确定为一个实际传输资源Actual#1，符号0和1确定为一个实际传输资源Actual#2，则如图7所示，将DMRS映射到S时隙的第14个符号，即Actual#1对应的符号，由此，映射的DMRS既可以作为Actual#1的解调参考信号，也可以作为Actual#2的解调参考信号，甚至可以作为Actual#3等后续实际传输资源的解调参考信号，由于解调参考信号相对于其他实际传输资源的时隙靠前，可以提高后续实际传输资源的解调效率。
示例三：
在本示例中，将解调参考信号映射到时隙边界后一个实际传输资源中的第一个有效符号上，其中，时隙边界后一个实际传输资源包含多个有效符号。即在本实施例中，如时隙边界后的实际传输资源包括多个有效符号，则将该灾后的实际传输资源的第一个符号作为解调参考信号的映射对象。
举例而言，如图8所示，划分出的逻辑传输资源Nominal#1跨时隙，1个符号在S时隙，2个符号在U时隙，因此，继续参照图8，即将S时隙的第14个符号确定为一个实际传输资源Actual#1，将U时隙的第1和第2(即符号0和1)个符号确定为一个实际传输资源Actual#2，则可以将解调参考信号映射到Actual#2中的第一个符号，即U时隙的符号0。由此，映射的DMRS既可以作为Actual#1的解调参考信号，也可以作为Actual#2的解调参考信号，甚至可以作为Actual#3等后续实际传输资源的解调参考信号，由于解调参考信号Actual#2位于其本身的第一个符号，因此，提高了Actual#2中的信息传输效率，并且，相对于其他后续实际传输资源的时隙靠前，可以提高后续实际传输资源的解调效率，且相对于Actual#1相对靠近，也可以用于Actual#1的信息传输。
示例四：
在本示例中，将解调参考信号映射到时隙边界后一个实际传输资源中的有效符号上，其中，时隙边界后一个实际传输资源包含一个有效符号。
举例而言，如图9所示，在本示例中，预先设置多个逻辑传输资源即图中的Nominal#，其中，若是Nominal#1中的符号12和13位于同一个时隙，符号0位于一个时隙，则将符号12和13确定一个实际传输资源Actual#1，将符号0确定为一个实际传输资源Actual#2，其中，可以将解调参考信号映射到Actual#2中的符号0上。由此，映射的DMRS既可以作为Actual#1的解调参考信号，也可以作为Actual#2的解调参考信号，甚至可以作为Actual#3等后续实际传输资源的解调参考信号，由于解调参考信号Actual#2位于其本身的第一个符号，因此，提高了Actual#2中的信息传输效率，并且，相对于其他后续实际传输资源的时隙靠前，可以提高后续实际传输资源的解调效率，且相对于Actual#1相对靠近，也可以用于Actual#1的信息传输。
当拆分位置包括无效符号时，将解调参考信号映射到至少一个实际传输资源中与拆分位置相邻的有效符号上的方式，至少具有如下的一种或多种：
示例一：
在本示例中，将解调参考信号映射到无效符号前一个实际传输资源中的最后一个有效符号上，其中，无效符号前一个实际传输资源包含多个有效符号。
举例而言，如图10所示，预先设置多个逻辑传输资源即图中的Nominal#，其中，若是Nominal#2中的符号2是无效传输符号，则如图10所示，Nominal#1中的符号0和1为一个实际传输资源Actual#2，符号3和4为一个实际传输资源Actual#3，则可以将DMRS映射到Actual#2中的最后一个有效符号即符号1中。由此，映射的DMRS既可以作为Actual#2的解调参考信号，也可以作为Actual#3的解调参 考信号，甚至可以作为Actual#4等后续实际传输资源的解调参考信号，由于解调参考信号相对于其他实际传输资源的时隙靠前，可以提高后续实际传输资源的解调效率。
示例二：
在本示例中，将解调参考信号映射到无效符号前一个实际传输资源中的有效符号上，其中，无效符号前一个实际传输资源包含一个有效符号。
举例而言，如图11所示，预先设置多个逻辑传输资源即图中的Nominal#，其中，若是Nominal#2中的符号3是无效传输符号，则如图10所示，Nominal#2中的符号2为一个实际传输资源Actual#3，符号4为一个实际传输资源Actual#4，则可以将DMRS映射到Actual#3中的有效符号即符号2上。由此，映射的DMRS既可以作为Actual#3的解调参考信号，也可以作为Actual#4的解调参考信号，甚至可以作为Actual#5等后续实际传输资源的解调参考信号，由于解调参考信号相对于其他实际传输资源的时隙靠前，可以提高后续实际传输资源的解调效率。
示例三：
在本示例中，将解调参考信号映射到无效符号后一个实际传输资源中的第一个有效符号上，其中，无效符号后一个实际传输资源包含多个有效符号。
举例而言，如图12所示，预先设置多个逻辑传输资源即图中的Nominal#，其中，若是Nominal#2中的符号2是无效传输符号，则如图12所示，Nominal#2中的符号3和4为一个实际传输资源Actual#3，则可以将DMRS映射到Actual#3中的第一个有效符号即符号3上。由此，映射的DMRS既可以作为Actual#3的解调参考信号，也可以作为Actual#2的解调参考信号，甚至可以作为Actual#4等后续实际传输资源的解调参考信号，由于解调参考信号相对于其他实际传输资源的时隙靠前，可以提高后续实际传输资源的解调效率。
示例四：
在本示例中，将解调参考信号映射到无效符号后一个实际传输资源中的有效符号上，其中，无效符号后一个实际传输资源包含一个有效符号。
举例而言，如图13所示，预先设置多个逻辑传输资源即图中的Nominal#，其中，若是Nominal#2中的符号3是无效传输符号，则如图13所示，Nominal#2中的符号2为一个实际传输资源Actual#3，符号4为一个实际传输资源Actual#4，则可以将DMRS映射到Actual#4中有效符号即符号4中。由此，映射的DMRS既可以作为Actual#3的解调参考信号，也可以作为Actual#4的解调参考信号，甚至可以作为Actual#5等后续实际传输资源的解调参考信号，由于解调参考信号相对于其他实际传输资源的时隙靠前，可以提高后续实际传输资源的解调效率。
当拆分位置既包括无效符号又包括时隙边界后时，将解调参考信号映射到至少一个实际传输资源中与拆分位置相邻的有效符号上的方式，可以参照上述实施例的结合，作为一种可能的实现方式，将解调参考信号映射到时隙边界前一个实际传输资源中的最后一个有效符号上，其中，时隙边界前一个实际传输资源包含多个有效符号，并且，将解调参考信号映射到无效符号前一个实际传输资源中的最后一个有效符号上，其中，所述无效符号前一个实际传输资源包含多个有效符号。
举例而言，如图14所示，将DMRS映射到S时隙的第14个符号，由此，映射的DMRS既可以作为Actual#1的解调参考信号，也可以作为Actual#2的解调参考信号，甚至可以作为Actual#3等后续实际传输资源的解调参考信号，由于解调参考信号相对于其他实际传输资源的时隙靠前，可以提高后续实际传输资源的解调效率。预先设置多个逻辑传输资源即图中的Nominal#，其中，若是Nominal#2中的符号4是无效传输符号，则如图14所示，Nominal#2中的符号2和3为一个实际传输资源Actual#3，则可以将DMRS映射到Actual#3中的最后一个有效符号即符号3中。由此，映射的DMRS既可以作为Actual#3的解调参考信号，也可以作为Actual#4的解调参考信号，甚至可以作为Actual#5等后续实际传输资源的解调参考信号，由于解调参考信号相对于其他实际传输资源的时隙靠前，可以提高后续实际传输资源的解调效率。从而，不但没有针对每个DMRS既可以实际传输资源映射DMRS，而且没有仅仅针对实际传输资源出现时隙边界或者无效符号的位置映射DMRS，结合时隙边界和无效符号的位置共同来确定DMRS，平衡了传输资源的有效利用和传输资源的消耗。
综上，本发明实施例的解调参考信号映射方法，灵活根据拆分位置前后的实际传输资源的情况映射解调参考信号，平衡了传输资源的有效利用和传输资源的消耗。
与上述几种实施例提供的解调参考信号映射方法相对应，本发明还提供一种解调参考信号映射装置，由于本发明实施例提供的解调参考信号映射装置与上述几种实施例提供的方法相对应，因此在解调参考信号映射方法的实施方式也适用于本实施例提供的解调参考信号映射装置，在本实施例中不再详细描述。
