背景技术
新一代新型互联网应用的不断涌现对无线通信技术提出了更高的要求，驱使无线通信技术不断演进以满足应用的需求。当下，蜂窝移动通信技术正处于新一代技术的演进阶段。新一代技术的一个重要特点就是要支持多种业务类型的灵活配置。不同的业务类型对无线通信技术有不同的要求，例如，增强移动宽带(enhanced Mobile Broad Band，简称eMBB)业务类型主要的要求侧重在大带宽和高速率等方面，超高可靠与低延迟的通信(Ultra Reliable Low Latency Communication，简称URLLC)业务类型主要的要求侧重在较高的可靠性和低时延方面，而海量机器类通信(massive Machine Type Communication，简称mMTC)业务类型主要的要求侧重在大的连接数方面。因此，新一代的无线通信系统需要灵活和可配置的设计来支持多种业务类型的传输。除此之外，新一代的无线通信技术也需要支持和现有通信技术的共存，以及保证技术演进的前向兼容性。
为了支持更灵活的资源重用方案，与长期演进(LTE)系统共存，或者与未来技术的前向兼容，基站可以以半静态的方式为用户设备(UE)配置一些被系统预先占用的时频资源位置，这些被系统预先占用的时频资源位置被称为预留集合(reserve set(s))。例如，系统分配给其他UE使用的控制信令传输的时频资源，当与LTE系统同频带共存时LTE系统的参考信号传输位置，为兼容未来技术预留的时频资源等。用户的下行数据传输不占用reserve set(s)已经占用的时频资源。当用户的下行控制信令中包含的下行调度信息指示的下行数据传输时频资源位置和reserve sets(s)的时频资源位置重合时，UE的下行数据传输不占用重合的时频资源位置，而以速率匹配(rate matching)的方式围绕那些重合的视频资源位置进行编码和物理资源映射。
另外，基站可以以动态信令的方式指示半静态配置的reserve set(s)中的一部分不可以被用户的下行数据传输所占用，而另一部分可以被用户的下行数据传输所占用。只有当用户的下行数据传输调度资源位置和不可以占用的reserve set(s)资源位置重合时，用户数据围绕着重合 位置进行速率匹配和物理资源映射。
而在通信系统中，参考信号通常会随着数据一起进行传输，以帮助接收端进行信道估计，相位跟踪和链路质量估计等，保证数据的正确接收。参考信号在数据块中的位置通常是预先给定或者配置好的，以方便用户接收。对于一些重要的参考信号如解调参考信号(DMRS)，UE需要首先从参考信号的接收中估计出正确的信道信息，才能够正确地恢复出数据信息。因此，当参考信号的时频资源位置与reserve set(s)重合时，如何传输参考信号是需要解决的一个技术问题。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
图1A是本申请一示例性实施例示出的一种参考信号的传输方法的流程图，该实施例从基站侧进行描述，如图1A所示，该参考信号的传输方法包括：
在步骤S101中，判断用于传输当前参考信号的时频资源位置与基站所在系统预先占用的时频资源位置是否有重合，若确定用于传输当前参考信号的时频资源位置与基站所在系统预先占用的时频资源位置有重合，则执行步骤S102或者步骤S103或者步骤S104或者步骤S105。
其中，用于传输当前参考信号的时频资源位置与基站所在系统预先占用的时频资源位置有重合包括用于传输当前参考信号的时频资源位置与基站所在系统预先占用的时频资源位置部分重合以及用于传输当前参考信号的时频资源位置与基站所在系统预先占用的时频资源位置完全重合。
在步骤S102中，在重合的时频资源位置取消向UE传输当前参考信号。
在该实施例中，当用于传输当前参考信号的时频资源位置与基站所在系统预先占用的时频资源位置完全重合时，可以在重合的时频资源位置取消向UE传输当前参考信号。
在步骤S103中，在重合的时频资源位置取消向UE传输当前参考信号，但在非重合的时频资源位置向UE传输当前参考信号。
在该实施例中，当用于传输当前参考信号的时频资源位置与基站所在系统预先占用的 时频资源位置部分重合时，可以在重合的时频资源位置取消向UE传输当前参考信号，但在非重合的时频资源位置向UE传输当前参考信号。
如图1B所示，解调参考信号(DMRS)的时频资源位置与reserve set1的时频资源位置有重合，基站在reserve set1取消向UE传输DMRS，相位追踪参考信号(PT-RS)和小区参考信号(C-RS)的时频资源位置均与reserve set2的时频资源位置有重合，基站在reserve set2取消向UE传输PT-RS和C-RS。
为了减少在重合的时频资源位置取消传输当前参考信号对于接收端数据接收的影响，可以改变位于非重合的时频资源位置上的当前参考信号的传输方式，并采用改变后的传输方式在非重合的时频资源位置向UE传输当前参考信号。其中，改变传输方式可以包括但不局限于增加传输功率、改变参考信号序列和改变参考信号序列长度中的至少一项。
另外，基站在采用改变后的传输方式在非重合的时频资源位置向UE传输当前参考信号时，还可以向UE发送当前参考信号的当前传输方式，以使UE可以通过预先定义、半静态配置或者动态指示等方法获知当前参考信号的当前传输方式，从而可以正确地接收当前参考信号。
需要说明的是，基站与UE采用相同或相应的方式获知当前参考信号的当前传输方式，例如，二者均采用预先定义的方式获知当前参考信号的当前传输方式，又例如，基站通过半静态配置的方式通知UE当前参考信号的当前传输方式，而UE接收基站半静态配置的当前参考信号的当前传输方式。
在步骤S104中，在非重合的时频资源位置向UE传输当前参考信号。
在该实施例中，当用于传输当前参考信号的时频资源位置与基站所在系统预先占用的时频资源位置部分重合或完全重合时，可以将用于传输当前参考信号的时频资源位置更改到非重合的时频资源位置，并在更改到的非重合的时频资源位置向UE传输当前参考信号。
其中，可以采用以下方式将用于传输当前参考信号的时频资源位置更改到非重合的时频资源位置：对用于传输当前参考信号的时频资源位置和频域资源位置中的至少一项进行移动，以使移动后的时频资源位置与基站所在系统预先占用的时频资源位置不重合。例如，如图1C所示，将当前参考信号DMRS、PT-RS和C-RS的传输在时域上向前或向后进行最小移动，在频域上向高或者向低进行最小移动，使得移动后的时频资源位置与基站所在系统预先占用的时频资源位置不重合。
另外，基站在更改到的非重合的时频资源位置向UE传输当前参考信号时，还可以向 UE发送当前参考信号的当前传输位置，以使UE可以通过预先定义、半静态配置或者动态指示等方法获知当前参考信号的当前传输位置，从而可以正确地接收当前参考信号。
需要说明的是，基站与UE采用相同或相应的方式获知当前参考信号的当前传输位置，例如，二者均采用预先定义的方式获知当前参考信号的当前传输位置，又例如，基站通过半静态配置的方式通知UE当前参考信号的当前传输位置，而UE接收基站半静态配置的当前参考信号的当前传输位置。
在步骤S105中，在重合的时频资源位置向UE传输当前参考信号。
在该实施例中，当用于传输当前参考信号的时频资源位置与基站所在系统预先占用的时频资源位置部分重合或完全重合时，可以采用原始的传输方式在重合的时频资源位置向UE传输当前参考信号，也可以改变当前参考信号的传输方式，并采用改变后的传输方式在重合的时频资源位置向UE传输当前参考信号。其中，改变传输方式可以包括但不局限于增加传输功率、改变参考信号序列和改变参考信号序列长度中的至少一项。
如图1D所示，DMRS的时频资源位置与reserve set1的时频资源位置有重合，基站采用原始的传输方式在reserve set1向UE传输DMRS，相位追踪参考信号(PT-RS)和小区参考信号(C-RS)的时频资源位置均与reserve set2的时频资源位置有重合，基站采用原始的传输方式在reserve set2向UE传输PT-RS和C-RS。
如图1E所示，DMRS的时频资源位置与reserve set1的时频资源位置有重合，基站采用改变后的传输方式在reserve set1向UE传输DMRS，相位追踪参考信号(PT-RS)和小区参考信号(C-RS)的时频资源位置均与reserve set2的时频资源位置有重合，基站采用改变后的传输方式在reserve set2向UE传输PT-RS和C-RS。
如果采用改变后的传输方式在重合的时频资源位置向UE传输当前参考信号，则在采用改变后的传输方式在重合的时频资源位置向UE传输当前参考信号时，还可以向UE发送当前参考信号的当前传输方式，以使UE可以通过预先定义、半静态配置或者动态指示等方法获知当前参考信号的当前传输方式，从而可以正确地接收当前参考信号。
上述实施例，在用于传输当前参考信号的时频资源位置与基站所在系统预先占用的时频资源位置有重合时，采用不同的处理方式传输当前参考信号或取消传输当前参考信号，实现手段灵活多样。
图2A是本申请一示例性实施例示出的另一种参考信号的传输方法的流程图，该实施例从基站侧进行描述，如图2A所示，该参考信号的传输方法包括：
在步骤S201中，为基站所在系统预先占用的时频资源位置配置优先级，并向UE发送为基站所在系统预先占用的时频资源位置配置的优先级。
由于系统预先占用时频资源的原因是多样的，随用户数据传输的参考信号的种类也是多样的，因此，对于不同的预先占用的时频资源和用户参考信号的组合可能有不同的处理方法。例如，对于用户数据接收比较重要的参考信号如前置的DMRS，应当尽量保证它的正确接收，因此，采用原始的传输方式在重合的时频资源位置向UE传输参考信号或者在非重合的时频资源位置向UE传输参考信号更加适合；而对于用户数据接收相对次要的一些参考信号，可以在重合的时频资源位置取消向UE传输参考信号，或者改变参考信号的传输方式，并采用改变后的传输方式在重合的时频资源位置向UE传输参考信号。
为了灵活地应对不同的参考信号和系统预先占用的时频资源位置重合，当基站为系统预先占用的时频资源位置配置优先级时，可以为不同的时频资源位置配置不同的优先级，并通过半静态或动态的下行信号配置给UE。
在步骤S202中，判断用于传输当前参考信号的时频资源位置与基站所在系统预先占用的时频资源位置是否有重合，若确定用于传输当前参考信号的时频资源位置与基站所在系统预先占用的时频资源位置有重合，则执行步骤S203。
在步骤S203中，若根据为基站所在系统预先占用的时频资源位置配置的优先级，确定能够传输当前参考信号的重合的时频资源位置，则在所确定的重合的时频资源位置向UE传输当前参考信号。
在该实施例中，当相同的参考信号(RS)与不同优先级的reserve set重合时，不在高优先级的reserve set上传输参考信号，但可以在低优先级的reserve set上传输参考信号。
例如，基站为reserve set1设置了高优先级，为reserve set2设置了低优先级，如图2B所示，在当前RS的时频资源位置与reserve set1和reserve set2均重合时，可以确定能够传输当前RS的重合的时频资源位置为reserve set2，则在reserve set2上向UE传输当前RS。
上述实施例，通过为基站所在系统预先占用的时频资源位置配置优先级，根据配置的优先级确定能够传输当前参考信号的重合的时频资源位置，并在所确定的重合的时频资源位置向UE传输当前参考信号，可以更灵活地对时频资源进行管理，并可以保证用户的数据接收质量。
图3A是本申请一示例性实施例示出的另一种参考信号的传输方法的流程图，该实施例从基站侧进行描述，如图3A所示，该参考信号的传输方法包括：
在步骤S301中，为不同参考信号配置传输策略，并向UE发送为不同参考信号配置的传输策略，上述传输策略是指不同参考信号的时频资源位置与不同优先级的基站所在系统预先占用的时频资源位置有重合时，不同参考信号所采用的传输策略。
其中，上述传输策略可以预先给定或者以半静态的方式由基站配置给UE。
在该实施例中，当不同参考信号的时频资源位置与相同优先级的基站所在系统预先占用的时频资源位置有重合时，可以在重合的时频资源位置传输对于用户数据接收比较重要的参考信号如前置的解调参考信号(DMRS)，但不可以在重合的时频资源位置传输对于用户数据接收相对次要的一些参考信号例如C-RS。例如，如图3B所示，DMRS和CRS的时频资源位置均与reserve set1重合，则可以在reserve set1上传输DMRS，但不可以传输C-RS。
在步骤S302中，判断用于传输当前参考信号的时频资源位置与基站所在系统预先占用的时频资源位置是否有重合，若确定用于传输当前参考信号的时频资源位置与基站所在系统预先占用的时频资源位置有重合，则执行步骤S303或者步骤S304。
在步骤S303中，根据与当前参考信号对应的传输策略在非重合的时频资源位置向UE传输当前参考信号。
若配置的传输策略为可以在非重合的时频资源位置向UE传输当前参考信号，则在非重合的时频资源位置向UE传输当前参考信号。
在步骤S304中，根据与当前参考信号对应的传输策略在重合的时频资源位置向UE传输当前参考信号。
若配置的传输策略为可以在重合的时频资源位置向UE传输当前参考信号，则在重合的时频资源位置向UE传输当前参考信号。
上述实施例，通过为不同参考信号配置传输策略，并据此传输当前参考信号，可以更灵活地对时频资源进行管理，并可以保证用户的数据接收质量。

图8A是根据一示例性实施例示出的另一种参考信号的传输装置的框图，如图8A所示，在上述图5所示实施例的基础上，该装置还可以包括：第一配置发送模块59。
第一配置发送模块59被配置为：为基站所在系统预先占用的时频资源位置配置优先级，并向UE发送为基站所在系统预先占用的时频资源位置配置的优先级。
由于系统预先占用时频资源的原因是多样的，随用户数据传输的参考信号的种类也是多样的，因此，对于不同的预先占用的时频资源和用户参考信号的组合可能有不同的处理方法。例如，对于用户数据接收比较重要的参考信号如前置的DMRS，应当尽量保证它的正确接收，因此，采用原始的传输方式在重合的时频资源位置向UE传输参考信号或者在非重合的时频资源位置向UE传输参考信号更加适合；而对于用户数据接收相对次要的一些参考信号，可以在重合的时频资源位置取消向UE传输参考信号，或者改变参考信号的传输方式，并采用改变后的传输方式在重合的时频资源位置向UE传输参考信号。
为了灵活地应对不同的参考信号和系统预先占用的时频资源位置重合，当基站为系统预先占用的时频资源位置配置优先级时，可以为不同的时频资源位置配置不同的优先级，并通过半静态或动态的下行信号配置给UE。
第三传输模块55被配置为：若根据第一配置发送模块59为基站所在系统预先占用的时频资源位置配置的优先级，确定能够传输当前参考信号的重合的时频资源位置，则在所确定的重合的时频资源位置向UE传输当前参考信号。
在该实施例中，当相同的参考信号(RS)与不同优先级的reserve set重合时，不在高优先级的reserve set上传输参考信号，但可以在低优先级的reserve set上传输参考信号。
例如，基站为reserve set1设置了高优先级，为reserve set2设置了低优先级，如图2B所示，在当前RS的时频资源位置与reserve set1和reserve set2均重合时，可以确定能够传输 当前RS的重合的时频资源位置为reserve set2，则在reserve set2上向UE传输当前RS。
上述实施例，通过为基站所在系统预先占用的时频资源位置配置优先级，根据配置的优先级确定能够传输当前参考信号的重合的时频资源位置，并在所确定的重合的时频资源位置向UE传输当前参考信号，可以更灵活地对时频资源进行管理，并可以保证用户的数据接收质量。

在该实施例中，当不同参考信号的时频资源位置与相同优先级的基站所在系统预先占用的时频资源位置有重合时，可以在重合的时频资源位置传输对于用户数据接收比较重要的参考信号如前置的解调参考信号(DMRS)，但不可以在重合的时频资源位置传输对于用户数据接收相对次要的一些参考信号例如C-RS。例如，如图3B所示，DMRS和CRS的时频资源位置均与reserve set1重合，则可以在reserve set1上传输DMRS，但不可以传输C-RS。
第二传输模块54可以被配置为：根据第二配置发送模块60配置的与当前参考信号对应的传输策略在非重合的时频资源位置向UE传输当前参考信号。
若配置的传输策略为可以在非重合的时频资源位置向UE传输当前参考信号，则在非重合的时频资源位置向UE传输当前参考信号。
第三传输模块55可以被配置为：根据第二配置发送模块60配置的与当前参考信号对应的传输策略在重合的时频资源位置向UE传输当前参考信号。
若配置的传输策略为可以在重合的时频资源位置向UE传输当前参考信号，则在重合的时频资源位置向UE传输当前参考信号。
上述实施例，通过为不同参考信号配置传输策略，并据此传输当前参考信号，可以更灵活地对时频资源进行管理，并可以保证用户的数据接收质量。
