Description

测量参考信号传输方法、装置、通信节点设备及存储介质 技术领域
本公开涉及通信技术领域。
背景技术
测量参考信号(Sounding Reference Signal，简称为SRS)是一种第二通信节点设备(例如用户设备(User Equipment，简称为UE))与第一通信节点设备(例如演进型基站(e-Node-B，eNB))之间用来测量信道状态信息(Channel State Information，简称为CSI)的信号。在长期演进(Long Term Evolution，LTE)系统中，UE按照eNB指示的频带、频域位置、序列循环移位、周期和子帧偏置等参数，定时在发送子帧的最后一个数据符号上发送上行SRS。eNB根据接收到的SRS判断UE上行的CSI，并根据得到的CSI进行频域选择调度、闭环功率控制等操作。
为了增强SRS的容量和覆盖，一种方式是考虑对上行常规子帧(Normal Subframe)引入多个SRS符号。但在一个上行子帧中引入多个SRS符号后，针对引入的多个SRS符号如何配置传输则成为急需解决的问题。

具体实施方式
为了使本公开的目的、技术方案及优点更加清楚明白，下面通过具体实施方式结合附图对本公开实施例作进一步详细说明。 应当理解，此处所描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。
本公开实施例提供了一种SRS传输方法，其可适用但不限于对上行子帧引入多个SRS符号的场景。如图1所示，该SRS传输方法可包括步骤S101-步骤S102。
在步骤S101中，根据配置信令信息和/或预设规则确定上行子帧中各SRS符号的配置信息。
应当理解的是，本公开实施例中的参考信号并不限于SRS，根据具体应用场景也可为其他参考信号。
根据本公开提供的实施例，根据具体需求，可以灵活的根据配置信令信息确定上行子帧中各SRS符号的配置信息；也可以灵活的根据预设规则确定上行子帧中各SRS符号的配置信息；或者根据配置信令信息和预设规则确定上行子帧中各SRS符号的配置信息。
根据本公开提供的实施例，当该方法包括根据预设规则确定上行子帧中各SRS符号的配置信息时，该预设规则可以是第一通信节点设备和第二通信节点设备之间预先协商好(也即预定义好)的规则。
根据本公开提供的实施例，当该方法包括根据配置信令信息确定上行子帧中各SRS符号的配置信息时，该配置信令信息可以是第一通信节点设备向第二通信节点设备发送的配置信令信息，且具体的配置信令信息类型也可根据具体应用场景灵活选择。
根据本公开提供的实施例，第一通信节点设备可以包括但不限于宏小区的基站、小小区(small cell)的基站或传输节点设备、高频通信系统中的发送节点设备、物联网系统中的发送节点设备等，第二通信节点设备可以包括但不限于UE、各种便携设备、汽 车通信系统等各种通信系统中的节点设备。
在步骤S102中，根据配置信息传输SRS符号。
根据本公开提供的实施例，根据配置信息传输SRS符号可包括但不限于：对于第二通信节点设备，其可根据配置信息向第一通信节点设备发送SRS符号；以及对于第一通信节点设备，其可根据配置信息接收第二通信节点设备发送过来的SRS符号。根据本公开提供的实施例，第一通信节点设备接收到该SRS符号后，还可对其进行相应的处理。
在一些应用示例(例如LTE-A Release 14(LTE-A版本14)，但并不限于LTE-A Release 14)中，上行子帧中的SRS符号可包括但不限于传统的SRS符号(legacy SRS symbol)和额外的SRS符号(additional SRS symbol)。
根据本公开提供的实施例，传统的SRS符号为上行子帧最后一个符号(在一些示例性实施例中，该符号可为数据符号)上的SRS符号；额外的SRS符号为上行子帧其他符号(在一些示例性实施例中，该符号也可为数据符号)上的SRS符号。
根据本公开实施例提供的SRS传输方法，第一通信节点设备和第二通信节点设备之间可以通过配置信令信息和/或预设规则确定上行子帧中传统的SRS符号和额外的SRS符号的配置信息，并可分别基于确定的配置信息接收和发送上行子帧中传统的SRS符号和额外的SRS符号，以满足在一个上行子帧中引入多个SRS符号以满足增强SRS的容量和覆盖的需求。
为了便于理解，本实施例下面对根据配置信令信息和/或预设规则确定上行子帧中各SRS符号的配置信息进行示例说明。
根据本公开提供的实施例，根据配置信令信息和/或预设规则确定上行子帧中各SRS符号的配置信息可包括但不限于对上行子 帧中传统的SRS符号和额外的SRS符号的SRS参数集进行确认，例如：根据第四配置信令信息分别独立确定传统的SRS符号和额外的SRS符号的SRS参数集；此处的独立确定是指针对传统的SRS符号的SRS参数集和额外的SRS符号的SRS参数集相对独立配置，这样可以对传统的SRS符号和额外的SRS符号进行独立的管理。
根据本公开提供的实施例，第一通信节点设备可在第四配置信令信息中携带SRS参数集的配置信息，并将该第四配置信令信息发给第二通信节点设备，第二通信节点设备可根据第四配置信令信息中携带的SRS参数集的配置信息，确定上行子帧中传统的SRS符号和额外的SRS符号的SRS参数集。
根据本公开提供的实施例，SRS参数集可包括但不限于以下至少之一：发送梳的数量、发送梳的索引、发送带宽、调频带宽、循环移位参数、天线端口数量、起始物理资源块分配位置。
根据本公开提供的实施例，第四配置信令信息可以是第一通信节点设备向第二通信节点设备发送的各种下行信令；例如，可包括但不限于无线资源控制(Radio Resource Control，RRC)信令和下行控制信息(Downlink Control Information，DCI)信令中的至少一种。
根据本公开提供的实施例，第一通信节点设备和第二通节点设备之间也可预定义传统的SRS符号和/或额外的SRS符号的SRS参数集；或者采用预定义和第四配置信息的结合的方式确定传统的SRS符号和额外的SRS符号的SRS参数集。
根据本公开提供的实施例，RRC信令和DCI信令的格式和结构等可以通过灵活选择确定。例如，在LTE系统这一示例性应用场景中，物理下行控制信道(Physical Downlink Control Channel，PDCCH)用于承载DCI；其中，DCI可包括上、下行调度信息， 以及上行功率控制信息。DCI格式(format)分为DCI format 0、1、1A、1B、1C、1D、2、2A、3，3A等，后面演进至LTE-A Release 12(LTE-A版本12)中又增加了DCI format 2B、2C、2D以支持多种不同的应用和传输模式。DCI信令的格式则可根据需求在上述示例的格式中灵活选择。
根据本公开提供的实施例，根据配置信令信息和/或预设规则确定上行子帧中各SRS符号的配置信息可包括但不限于确定上行子帧中传统的SRS符号和额外的SRS符号的SRS序列产生方式。
例如，在一种示例性实施例中，可根据预设SRS序列产生规则(该规则可以是但不限于第一通信节点设备和第二通信节点设备之间预先定义好的规则)确定传统的SRS符号和额外的SRS符号的SRS序列产生方式；其中，预设SRS序列产生规则可包括但不限于以下至少之一：传统的SRS符号的SRS序列基于物理小区ID(PCID)产生；额外的SRS符号的SRS序列基于虚拟小区ID(VCID)或SRS序列ID产生。
这样，针对不同版本的第二通信节点设备在上行子帧的最后一个符号上的SRS采用的SRS序列产生方式可统一，因此可实现不同版本的第二通信节点设备在上行子帧的最后一个符号上SRS正交复用。例如，可实现Release 14的第二通信节点设备与Release 15及Release 15之前版本的第二通信节点设备在上行子帧的最后一个符号上实现SRS正交复用。
根据本公开提供的实施例，SRS序列产生规则并不限于上述示例的两种规则，也可以根据需求采用物理小区ID、虚拟小区ID和SRS序列ID的灵活组合确定传统的SRS符号和/或额外的SRS符号的SRS序列产生方式。根据本公开提供的实施例，虚拟小区ID和/或SRS序列ID可以是第一通信节点设备配置的，也可通过其他方式获取。
根据本公开提供的实施例，传统的SRS符号和额外的SRS符号的SRS序列产生方式并不限于通过第一通信节点设备和第二通信节点设备预定义的方式确定，也可通过配置信令信息动态配置，或者配置信令信息和预定义结合的方式确定。
例如，在一些示例性实施例中，根据配置信令信息和/或预设规则确定上行子帧中各SRS符号的配置信息可包括但不限于：根据第一配置信令信息确定上行子帧中传统的SRS符号和/或额外的SRS符号的SRS序列产生方式；其中该第一配置信令信息可包括但不限于用于指示SRS序列基于物理小区ID、虚拟小区ID或SRS序列ID等产生的序列产生方式指示信息。
根据本公开提供的实施例，第一通信节点设备可将该指示信息携带在第一配置信令中发给第二通信节点设备，第二通信节点设备即可根据该第一配置信令中的配置信息确定相应传统的SRS符号和/或额外的SRS符号的SRS序列产生方式。
根据本公开提供的实施例，第一配置信令信息可包括但不限于以下至少之一：无线资源控制RRC信令；下行控制信息DCI信令。
例如，在一些示例性应用场景中，第一通信节点设备可通过RRC信令或者物理下行控制信令向第二通信节点设备指示SRS序列是基于物理小区ID产生，还是基于虚拟小区ID或SRS序列ID产生；其中，虚拟小区ID和/或SRS序列ID可由第一通信节点设备配置。例如，第一通信节点设备可在SRS的RRC参数集中新增一个参数，用于指示所在RRC参数集中的SRS序列是基于物理小区ID产生还是基于虚拟小区ID或SRS序列ID产生。因此，第一通信节点设备可通过下行信令动态指示SRS序列是基于物理小区ID产生还是基于虚拟小区ID或SRS序列ID产生。
根据本公开提供的实施例，根据配置信令信息和/或预设规则 确定上行子帧中各SRS符号的配置信息还包括：确定第一配置信令信息(也即SRS序列的动态选择方式)适用的符号区域，该符号区域包括但不限于以下中的至少一种：上行子帧的最后一个符号；符合SRS周期及子帧偏置的所在上行子帧的最后一个符号；额外的SRS符号。
根据本公开提供的实施例，上述符号区域可以通过第一通信节点设备与第二通信节点设备之间通过预定义的方式确定。
根据本公开提供的实施例，上述符号区域可以通过第一通信节点设备(当然也可是其他设备)向第二通信节点设备动态指示的方式确定。
在一些示例性应用场景中，由于传统(例如包括但不限于Release 15及Release 15之前版本)的第二通信节点设备的发送子帧(也即上行子帧)的最后一个符号是否有SRS发送，可以通过RRC半静态配置，也可以是通过DCI动态触发；因此，通过动态触发时，则可通过本公开实施例中的SRS序列动态选择的方法，避免Release 14第二通信节点设备与传统第二通信节点设备在子帧的最后一个符号上SRS序列冲突的问题，实现SRS序列的正交复用。
根据本公开提供的实施例，根据配置信令信息和/或预设规则确定上行子帧中各SRS符号的配置信息可包括但不限于确定上行子帧中传统的SRS符号和/或额外的SRS符号的SRS频率跳转图样。
例如，第一通信节点设备和第二通信节点设备可以根据预设规则(也即二者之间预定义)确定上行子帧中传统的SRS符号和/或额外的SRS符号的SRS频率跳转图样；第一通信节点设备和第二通信节点设备也可以根据配置信令信息(例如第一通信节点设备向第二通信节点设备发送配置信令信息)确定上行子帧中传统 的SRS符号和/或额外的SRS符号的SRS频率跳转图样；或者，采用上述两种方式的结合确定上行子帧中传统的SRS符号和/或额外的SRS符号的SRS频率跳转图样。
根据本公开提供的实施例，根据第一通信节点设备和第二通信节点设备之间的预定义(也即通过预设规则)确定上行子帧中传统的SRS符号和/或额外的SRS符号的SRS频率跳转图样可包括：在传统的SRS符号的SRS序列是基于物理小区ID产生时，该传统的SRS符号采用第一SRS频率跳转图样；其中，该第一SRS频率跳转图样可以采用但不限于Release 15及Release 15之前版本的第二通信节点设备所采用的SRS频率跳转图样；在传统的SRS符号的SRS序列是基于虚拟小区ID或SRS序列ID产生时，该传统的SRS符号采用第二SRS频率跳转图样；其中，该第二SRS频率跳转图样可为但不限于多个额外的SRS符号之间进行SRS频率跳转的图样，也即与额外的SRS符号之间的SRS频率跳转图样保持一致。
根据本公开提供的实施例，额外的SRS符号所采用的SRS频率跳转图样也可采用但不限于上述方式确定，或者直接由其他设备配置确定。根据本公开实施例提供的方法，可确定出上行子帧中传统的SRS符号和/或额外的SRS符号的SRS频率跳转图样。
根据本公开提供的实施例，根据配置信令信息和/或预设规则确定上行子帧中各SRS符号的配置信息可包括但不限于确定上行子帧中传统的SRS符号和/或额外的SRS符号的频率跳转顺序。
例如，第一通信节点设备和第二通信节点设备可以根据预设规则(也即二者之间预定义)确定上行子帧中传统的SRS符号和/或额外的SRS符号的频率跳转顺序；第一通信节点设备和第二通信节点设备也可以根据配置信令信息(例如第一通信节点设备向第二通信节点设备发送配置信令信息)确定上行子帧中传统的 SRS符号和/或额外的SRS符号的频率跳转顺序；或者，采用上述两种方式的结合确定上行子帧中传统的SRS符号和/或额外的SRS符号的SRS频率跳转顺序。
根据本公开提供的实施例，频率跳转顺序包括但不限于以下之一：从上行子帧的最后一个符号往前跳；先跳上行子帧的最后一个符号，然后再从上行子帧的符号中从前往后跳。
为了便有理解，本公开实施例下面结合一种具体应场景进行示例说明。
在一些示例中，对于周期SRS或者非周期SRS的传输，频率跳转可从上行子帧的最后一个符号从后往前进行。例如，参见图2所示，配置的SRS频域位置是用于符号13的，然后跳频开始往前，即图2中箭头方向按序依次在符号13、符号12、符号11以及符号10上跳转。对于用户专有的SRS发送编号，依次在符号13、符号12、符号11、符号10上递增。
在LTE-A Release 10(LTE-A版本10)这一示例性场景中，在上行通信中，可使用非预编码的SRS，即天线专有的SRS；而对物理上行共享信道(Physical Uplink Shared Channel，简称为PUSCH)的用于解调的参考信号(De Modulation Reference Signal，简称为DMRS)则进行预编码。第一通信节点设备通过接收非预编码的SRS，可估计出上行的原始CSI，而经过了预编码的DMRS则不能使第一通信节点设备估计出上行原始的CSI。此时，当第二通信节点设备使用多天线发送非预编码的SRS时，每个UE所需要的SRS资源都会增加，也就造成了系统内可以同时复用的第二通信节点设备数量下降。第二通信节点设备可通过高层信令(也称为通过trigger type 0触发)或下行控制信息(也称为通过trigger type 1触发)这两种触发方式发送SRS，基于高层信令触发的可为周期SRS，基于下行控制信息触发的可为非周期SRS。
在本实施例的另一些示例中，对于周期SRS或者非周期SRS的传输，频率跳转可先跳上行子帧的最后一个符号，然后再从上行子帧的符号中从前往后跳。例如，可依次在符号13、符号10、符号11以及符号12上跳转。对于用户专有的SRS发送编号，依次在符号13、符号10、符号11以及符号12上递增。
根据本公开提供的实施例，周期SRS或者非周期SRS的传输的频率跳转顺序并不限于上述示例的跳转顺序。
根据本公开提供的实施例，根据配置信令信息和/或预设规则确定上行子帧中各SRS符号的配置信息可包括但不限于确定上行子帧中传统的SRS符号和/或额外的SRS符号的频率跳转方式。
例如，第一通信节点设备和第二通信节点设备可以根据预设规则(也即二者之间预定义)确定上行子帧中传统的SRS符号和/或额外的SRS符号的频率跳转方式；第一通信节点设备和第二通信节点设备也可以根据配置信令信息(例如第一通信节点设备向第二通信节点设备发送配置信令信息)确定上行子帧中传统的SRS符号和/或额外的SRS符号的频率跳转方式；或者，采用上述两种方式的结合确定上行子帧中传统的SRS符号和/或额外的SRS符号的SRS频率跳转方式。
根据本公开提供的实施例，根据配置信令信息和/或预设规则确定上行子帧中传统的SRS符号和/或额外的SRS符号的频率跳转方式包括但不限于：在传统的SRS符号上，采用第一频率跳转方式或第二频率跳转方式；在额外的SRS符号上，采用第二频率跳转方式。其中，第一频率跳转方式为SRS在多个子帧间进行跳转的方式；第二频率跳转方式为SRS在子帧内的多个SRS符号间进行跳转的方式。
例如，在一种示例性应用场景中，对于周期SRS，如果是在子帧的最后1个符号上，即在传统的SRS符号上，采用第一频率 跳转方式，例如，按照Release 15LTE的方式跳频；如果是在额外的SRS符号上，采用第二频率跳转方式，也即采用新的跳频方式进行跳频，最后1个符号跳频过的就不再跳了。
根据本公开提供的实施例，针对上述第二频率跳转方式(也即新的跳频方式)，可通过但不限于以下至少之一确定SRS的频域位置：(1)通过第二配置信令(例如该第二配置信令包括但不限于RRC信令和DCI信令中的任意一种)信息为各额外的SRS符号分别配置SRS频域位置；(2)通过第二配置信令信息为传统的SRS符号配置SRS频域位置参数n RRC，通信节点设备基于n RRC计算得到SRS的频域位置n b，额外的SRS符号上的频域位置通过预定义的方式获得；(3)通过第二配置信令信息为一个额外的SRS符号配置SRS频域位置，其余额外的SRS符号的SRS频域位置通过预定义的方式获得。

子。
本公开实施例提供的SRS传输方法可实现上行子帧中传统的 SRS符号和/或额外的SRS符号的频率跳转方式的配置确定。
根据本公开提供的实施例，根据配置信令信息和/或预设规则确定上行子帧中各SRS符号的配置信息可包括但不限于确定上行子帧中额外的SRS符号的时域位置。
根据本公开提供的实施例，第一通信节点设备和第二通信节点设备可以通过第三配置信令信息确定额外的SRS符号的时域位置，其中的时域位置可包括但不限于以下之一：上行子帧的第一个时隙或第二个时隙上的所有时域符号；上行子帧上的所有时域符号。
例如，在一种具体应用场景中，第一通信节点设备在小区专有的SRS参数中，除了指示小区专有的SRS周期和子帧偏置，还可使用1(该数量可以灵活调整)比特指示额外的SRS符号的时域位置。
根据本公开提供的实施例，传统的SRS符号的时域位置的确定可采用但不限于上述方式确认。可见，根据本公开实施例提供的SRS传输方法，可实现上行子帧中SRS符号的时域位置的确定。
根据本公开提供的实施例，根据配置信令信息和/或预设规则确定上行子帧中各SRS符号的配置信息可包括但不限于确定上行子帧中SRS符号的频率跳转与天线切换顺序。
例如，第一通信节点设备和第二通信节点设备可以根据预设规则(也即二者之间预定义)确定上行子帧中SRS符号的频率跳转与天线切换顺序；第一通信节点设备和第二通信节点设备也可以根据配置信令信息(例如第一通信节点设备向第二通信节点设备发送配置信令信息)上行子帧中SRS符号的频率跳转与天线切换顺序；或者，采用上述两种方式的结合确定上行子帧中SRS符号的频率跳转与天线切换顺序。
根据本公开提供的实施例，频率跳转与天线切换顺序包括但不限于以下之一：在多个SRS符号上，先进行频率跳转，再进行天线切换；在多个SRS符号上，先进行天线切换，再进行频率跳转；将一个或多个上行子帧的多个SRS符号分为多个组，组内SRS符号上的SRS发送端口索引相同，相邻的组间的SRS符号上的SRS发送端口索引不同。
根据本公开提供的实施例，天线切换时中间可预留间隙gap，且该间隙的大小可以为1个符号或多个符号等，具体可根据具体应用场景(例如包括但不限于UE所使用的子载波间隔)灵活确定。
为了便于理解，下面结合图3所示的天线切换和频率跳转的图样进行示例说明。在图3中，UE的天线配置为1发2收(1T2R)，一个子帧内分别在不同的4个子带(Subband#0～Subband#3)上进行频率跳转。由于跳转图样a所需的保护间隔要少于跳转图样b所需的保护间隔，因此跳转图样a优于跳转图样b。因此，一般来说，对于xTyR的UE天线配置，配置的SRS符号数量需要为y/x的倍数，这样N个SRS符号可以划分为y/x组，每一组N/(y/x)个符号相邻，用于使用相同天线端口的SRS发送。由于相邻组之间使用不同的天线端口，因此符号组之间需要预留1个或多个符号的保护间隔。如图3中的(a)图样所示，xTyR＝1T2R，N＝4，所以4个SRS符号被划分为两组，第一组包括符号9和符号10，使用Tx0发送SRS，第二组包括符号12和符号13，使用Tx1发送SRS。符号11被预留为保护间隔。
本公开实施例还提供了一种SRS传输装置，该SRS传输装置可在第一通信节点设备和第二通信节点设备上设置，第一通信节点设备上的SRS传输装置可用于执行第一通信节点设备侧的SRS传输方法对应的功能；第二通信节点设备上的SRS传输装置可用于执行第二通信节点设备侧的SRS传输方法对应的功能。
如图4所示，根据本公开提供的实施例，SRS传输装置可包括确定模块401和传输模块402。

根据本公开提供的实施例，根据具体需求，确定模块401可以灵活的根据配置信令信息确定上行子帧中各SRS符号的配置信息；也可以灵活的根据预设规则确定上行子帧中各SRS符号的配置信息；或者，根据配置信令信息和预设规则确定上行子帧中各SRS符号的配置信息。
根据本公开提供的实施例，当确定模块401配置为根据预设规则确定上行子帧中各SRS符号的配置信息时，该预设规则可以是第一通信节点设备和第二通信节点设备之间预先协商好(也即预定义好)的规则。
根据本公开提供的实施例，当确定模块401配置为根据配置信令信息确定上行子帧中各SRS符号的配置信息时，该配置信令信息可以是第一通信节点设备向第二通信节点设备发送的配置信令信息，且具体的配置信令信息类型也可根据具体应用场景灵活选择。
传输模块402，配置为根据配置信息传输SRS符号。
例如，对于第二通信节点设备上的SRS传输装置，其传输模块402可根据配置信息向第一通信节点设备发送SRS符号；对于第一通信节点设备上的SRS传输装置，其传输模块402可根据配置信息接收第二通信节点设备发送过来的SRS符号。根据本公开提供的实施例，第一通信节点设备接收到该SRS符号后，还可对其进行相应的处理。
