Description

参考信号发送方法、参考信号接收方法及通信装置
本申请要求于2020年01月10日提交中国专利局、申请号为202010026660.2、申请名称为“参考信号发送方法、参考信号接收方法及通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种参考信号发送方法、参考信号接收方法及通信装置。
背景技术
为了应对未来爆炸性的移动数据流量增长、海量移动通信的设备连接、不断涌现的各类新业务和应用场景，第五代(the fifth generation，5G)通信系统应运而生。5G通信系统可以支持不同的业务，例如，增强的移动宽带(enhanced Mobile Broadband，eMBB)业务、海量机器类型通信(massive machine type communication，MTC)业务、超可靠低延迟通信(ultra-reliable and low latency communications，URLLC)业务、多媒体广播多播(multimedia broadcast multicast service，MBMS)业务和定位业务等。
URLLC业务为5G通信系统中的一个重要的业务，传输时要求非常高的可靠性和非常短的时延。因此，为了保证URLLC业务的可靠性，5G通信系统中的网络设备和终端设备之间可以采用多次重复传输(repetition)的方式，传输URLLC业务数据。即，网络设备和终端设备之间可以通过N次传输机会重复传输同一URLLC业务数据N次。
现有协议支持探测参考信号(Sounding reference signal，SRS)的重传(repetition)。但是，对于非周期SRS，仅支持时隙内的重传，并不支持时隙间的重传，从而，潜在地，存在SRS的覆盖问题。因此，需要研究新的SRS传输方法。
发明内容
本申请实施例公开了一种参考信号发送方法、参考信号接收方法及通信装置，能够减少传输时延，提高通信效率。
第一方面，本申请实施例提供了一种参考信号传输方法，该方法包括：第一通信节点通过N个绑定且连续的时间单元向第二通信节点发送1个或多个参考信号；所述N为大于1的整数。
可选的，所述第一通信节点为终端设备(例如手机)，所述第二通信节点为网络设备(例如基站)，所述参考信号为上行参考信号，例如探测参考信号(Sounding reference signal，SRS)。可选的，所述第一通信节点为网络设备(例如基站)，所述第二通信节点为终端设备(例如手机)，所述参考信号为下行参考信号，例如小区参考信号(Cell Reference Signal，CRS)。可选地，所述第二通信节点可以将所述1个或多个参考信号作为一个整体进行处理以得到目标参考信号。示例性的，所述第二通信节点将所述1个或多个参考信号做软合并 处理以得到目标参考信号。所述时间单元可以是时隙、子帧、微时隙、无线帧传输时间间隔(Transmission Time Interval，TTI)等。可选的，所述1个或多个参考信号中每个参考信号对应的绑定且连续的时间单元的个数相同。示例性的，每个时间单元对应一个参考信号。示例性的，每个时间单元对应多个参考信号，例如2、3、4等，本申请不作限定。可以理解，所述第一通信节点可通过多个连续的时间单元向所述第二通信节点发送1个或多个参考信号，并且所述多个连续的时间单元是绑定在一起的。应理解，第一通信节点可维持着N个连续时间单元的相位连续性，因此可以通过N个绑定且连续的时间单元向第二通信节点发送1个或多个参考信号。示例性的，所述连续的时间单元，是指连续的上行时间单元。可选地，所述N个绑定且连续的时间单元的绑定方式，是指在N个连续的时间单元重复发送相同的信道或者信号。可选的，所述N个绑定且连续的时间单元的绑定方式(Time bundling)类似于子帧捆绑(TTI bundling)。在当前采用的参考信号传输方案是通过一个时间单元传输一个或者多个参考信号，当第一通信节点的发射功率较低或者信道质量较差时，第二通信节点很可能不能准确地获得该第一通信节点发送的参考信号，这样则会影响系统地性能。
本申请实施例中，第一通信节点通过N个绑定且连续的时间单元向第二通信节点发送1个或多个参考信号，使得该第二通信节点可以将该多个参考信号作为一个整体进行处理以得到准确的参考信号，通过时间累积能够提升信号能量，从而提高系统性能。
在一些可选的实现方式中，所述方法还包括：所述第一通信节点向所述第二通信节点发送能力信令；所述能力信令指示所述第一通信节点具备时间绑定能力或者不具备所述时间绑定能力，所述时间绑定能力为通过至少两个绑定且连续的时间单元重复发送参考信号的能力。
在该实现方式中，第一通信节点通过向第二通信节点发送能力指令，可以指示该第一通信节点是否具备时间绑定能力，以便于后续通过N个绑定且连续的时间单元向第二通信节点发送1个或多个参考信号。
在一些可选的实现方式中，所述能力信令包括第一字段和第二字段，所述第一字段指示所述第一通信节点具备时间绑定能力或者不具备所述时间绑定能力，所述第二字段指示最大时间绑定尺寸，所述最大时间绑定尺寸为所述第一通信节点发送参考信号可占用的绑定且连续的时间单元的最大个数。
在该实现方式中，第一通信节点通过向第二通信节点发送能力指令可以准确地指示目标时间绑定尺寸，占用的比特位较少。
在一些可选的实现方式中，所述第一通信节点通过N个绑定且连续的时间单元向第二通信节点发送1个或多个参考信号包括：所述第一通信节点根据配置信息，通过所述N个绑定且连续的时间单元向所述第二通信节点发送所述1个或多个参考信号；所述配置信息用于配置目标时间绑定尺寸，所述目标时间绑定尺寸为所述第一通信节点发送参考信号可占用的绑定且连续的时间单元的个数。

请参阅图1，图1是本申请实施例公开的一种网络构架示意图。如图1所示，该网络构架适用于多时间单元传输参考信号的场景，即通过多个绑定且连续的时间单元传输参考信号的场景。网络设备是网络侧的一种用于发射或接收信号的实体，如gNB。终端设备是用户侧的一种用于接收或发射信号的实体，如手机。由于基站和UE的应用场景较多，下面以基站作为网络设备的示例，以用户设备(user equipment，UE)作为终端设备的示例。如图1所示，该网络架构包括基站(base station)、UE1、UE2以及UE3。在该通信系统中，基站可以给UE1～UE3发送下行参考信号；UE1～UE3可以根据下行参考信号进行下行信道估计、下行信道质量测量、小区搜索等。在该通信系统中，UE1～UE3可以向基站发送上行参考信号(例如SRS)；基站可以根据上行参考信号进行上行信道估计、上行信道质量测量等。
下面来详细描述本申请实施例提供的参考信号发送方法和参考信号接收方法。
图2为本申请实施例提供的一种参考信号发送方法流程图。如图2所示，该方法可包括：
201、第一通信节点通过N个绑定且连续的时间单元向第二通信节点发送1个或多个参考信号。
可选的，上述1个或多个参考信号中每个参考信号对应的绑定且连续的时间单元的个数相同，上述N为大于1的整数。可选的，上述第一通信节点为终端设备(例如手机)，上述第二通信节点为网络设备(例如基站)，上述参考信号为上行参考信号，例如探测参考信号(Sounding reference signal，SRS)。可选的，上述第一通信节点为网络设备(例如基站)，上述第二通信节点为终端设备(例如手机)，上述参考信号为下行参考信号，例如小区参考信号(Cell Reference Signal，CRS)。
可选地，上述第二通信节点可以将上述1个或多个参考信号作为一个整体进行处理以得到目标参考信号。示例性的，上述第二通信节点将上述1个或多个参考信号做软合并处理以得到目标参考信号。示例性的，上述第二通信节点也可以将上述1个或多个参考信号的信道估计结果做软合并处理以得到目标信道估计结果。上述时间单元可以是时隙、子帧、微时隙、无线帧传输时间间隔(Transmission Time Interval，TTI)等，本申请不作限定。可选的，上述1个或多个参考信号中每个参考信号对应的绑定且连续的时间单元的个数相同。示例性的，每个时间单元对应一个参数信号。示例性的，每个时间单元对应多个参数信号，例如2、3、4等，本申请不作限定。可以理解，上述第一通信节点可通过多个连续的时间单元向上述第二通信节点发送1个或多个参考信号，并且上述多个连续的时间单元是绑定在一起的。应理解，第一通信节点可以维持着N个连续时间单元的相位连续性，因此可以通过N个绑定且连续的时间单元向第二通信节点发送1个或多个参考信号。示例性的，所述连续的时间单元，是指连续的上行时间单元。可选地，所述N个绑定且连续的时间单元的绑定方式，是指在N个连续的时间单元重复发送相同的信道或者信号。可选的，上述N 个绑定且连续的时间单元的绑定方式类似于子帧捆绑(TTI bounding)，即将一个SRS在连续多个时间单元上重复进行传输。图3为本申请实施例提供的一种传输1个或多个参考信号的N个绑定且连续的时间单元的示意图。如图3所示，301、302、303以及304分别对应一个时间单元，每个时间单元发送一个参考信号。图3仅为一个示例，本申请仅将上述N仅限定为大于1的整数，上述N可以是2、3、4等。
在一些实施例中，第一通信节点在接收来自第二通信节点发送的SRS触发指令之后，执行步骤201，即非周期性发送SRS。
在一些实施例中，第一通信节点可以周期性发送SRS。也就是说，第一通行节点可以周期性的执行步骤201。
本申请实施例中，第一通信节点通过N个绑定且连续的时间单元向第二通信节点发送1个或多个参考信号，使得该第二通信节点可以将该1个或多个参考信号作为一个整体进行处理以得到准确的参考信号，进而更准确地进行信道估计、信道质量检测等，能够减少传输时延，提高系统性能。
图1描述了第一通信节点通过N个绑定且连续的时间单元向第二通信节点发送1个或多个参考信号的方式。应理解，第一通信节点需要具备时间绑定(time bundling)能力，即通过多个绑定且连续的时间单元发送参考信号的能力，下面来介绍第二通信节点如何确定第一通信节点是否具备时间绑定能力的方式。
在一些实施例中，第一通信节点可以向第二通信节点发送能力指令，以指示该第一通信节点具备时间绑定(time bundling)能力或者不具备上述时间绑定能力。可选的，第一通信节点接收来自第二通信节点的能力查询指令之后，向上述第二通信节点发送上述能力指令。上述能力查询指令用于查询上述第一通信节点是否具备时间绑定能力。
可选的，上述时间绑定能力为SRS时间绑定(SRS time bundling)能力。上述时间绑定能力为通过至少两个绑定且连续的时间单元重复发送参考信号的能力。可以理解，第一通信节点向第二通信节点发送能力指令之后，如果第二通信节点使能参考信号的时间绑定，则该第一通信节点就可以利用该时间绑定能力向该第二通信节点发送参考信号，即通过多个绑定且连续的时间单元向第二通信节点发送1个或多个参考信号。
可选的，上述能力信令包括第一字段和第二字段，上述第一字段指示上述第一通信节点具备时间绑定能力或者不具备上述时间绑定能力，上述第二字段指示最大时间绑定尺寸(time bundling size)，上述最大时间绑定尺寸为上述第一通信节点发送参考信号最多可占用的绑定且连续的时间单元的最大个数。可选的，目标时间绑定尺寸为SRS目标时间绑定尺寸(SRS time bundling size)，即连续发送的SRS的个数。示例性的，第一字段包括一个比特位，若该比特位为0，表示第一通信节点不具备时间绑定能力；若该比特位为1，表示该第一通信节点具备时间绑定能力。示例性的，第二字段包括K个比特位，该K个比特用于指示目标时间绑定尺寸，K为大于1的整数。例如，K为2，第二字段为10，该第二字段表示最大时间绑定尺寸为2。又例如，K为2，第二字段为11，该第二字段表示最大时间绑定尺寸为3。图4为本申请实施例提供的一种能力指令的结构示意图。如图4所示，能力指令包括第一字段401和第二字段402。举例来说，第一字段401为1，该第一字段401表示第一通信节点具备时间绑定能力。又举例来说，第一字段401为1，第二字段为10， 该第一字段401表示第一通信节点，具备时间绑定能力，该第二字段402指示最大时间绑定尺寸为2。
