  • reference signals In a wireless communication system, there are many different types of reference signals, each of which plays an important role in different aspects. There are mainly the following types of reference signals.
  • the first type is a synchronization signal
  • the synchronization signal is mainly used for synchronization between the transmitting end and the receiving end, including a downlink synchronization signal (Synchronization Signal, SS for short) and an uplink synchronization signal or a random access signal (Radom access signal, referred to as RAS).

  • SSS secondary synchronization signal
  • the former is mainly used for basic time interval synchronization, and the latter is used for time interval unit sequence number. Alignment.
  • the second type is the measurement reference signal, also known as the measurement pilot, which is mainly used for measurement and feedback at the receiving end. According to different measurement purposes, it can be divided into RRM measurement, beam measurement, channel state information (CSI) measurement, and large-scale properties measurement. There are mainly the following types of measurement pilots:
  • the downlink CSI measurement channel (CSI-RS) is mainly used for downlink channel information CSI measurement, but can also be used for beam measurement, mobility measurement, and large-scale characteristic measurement;
  • the uplink sounding reference signal is mainly used for uplink channel information CSI measurement, but can also be used for beam measurement, mobility measurement, and large-scale characteristic measurement;
  • Mobility reference signal mainly used for mobility-related measurement, may be an independent signal or a synchronization signal, a reference demodulation signal of a broadcast channel, or a beam measurement reference signal, and CSI-RS signal;
  • BRS Beam Reference Signal
  • Feature Measurement Pilot Used for large-scale characteristic measurements, including delay spread, Doppler spread, Doppler shift, average gain, and average gain (average gain and average) Measurement of characteristics such as delay), frequency shift, average received power, Received Timing, channel correlation, and arrival angle may be independent guides. Frequency, it is also possible to use other functions of the pilot to increase the density to take into account the measurement of large-scale characteristics.
  • the third type is a reference demodulation signal, which is also referred to as a reference demodulation pilot.
  • the transmitting end can perform precoding data/control transmission according to the channel information, and can adopt one or more layers of multi-antenna transmission. technology. Generally, each layer has a corresponding Demodulation Reference Signal (DMRS), and the data or control information is demodulated by demodulating the channel estimated by the reference pilot and combining the received signal;
  • DMRS Demodulation Reference Signal
  • Reference demodulation pilot for data Reference demodulation for data channels, which can be configured with multiple ports; reference demodulation pilots including uplink data and reference demodulation pilots for downlink data.

  • the reference demodulation pilot of the broadcast channel may be an independent reference demodulation pilot, or may use a synchronization signal, or a BRS, for reference demodulation.
  • the DMRS can be used for measurement feedback of CSI (Channel State Information) in addition to demodulation.
  • CSI Channel State Information
  • the fourth type of pilot is a phase noise compensation reference signal (PNCRS), which is also called a phase noise compensation pilot.
  • PCRS phase noise compensation reference signal
  • This type of pilot is generally used for phase compensation when the phase noise is relatively large. It is used for frequency offset tracking, so it can also be considered as a frequency offset estimation pilot.
  • Some cases of this kind of pilot are appearing separately, and some cases appear as a step of DMRS, mainly because phase noise compensation is mainly used for data demodulation, which can also be understood as special demodulation pilot. If it is also defined on the transport layer, each layer corresponds to a phase noise supplemental pilot port, which can be considered as part of the DMRS.
  • the parameter configuration of the foregoing reference signal is generally determined by the base station, and then notified to the terminal by signaling.
  • Common reference signal configurations include reference signal density and time-frequency position, number of reference signal ports, and reference signal. Power and so on. These configurations generally adopt the configuration of explicit signaling, that is, the status bits in the signaling directly indicate the time-frequency location, the number of ports, the power, and the like.

  • the related configurations involving the above reference signals all involve relationship indication information between multiple reference signals.
  • the main idea of reference signal parameter configuration is also through explicit control. Signaling is configured, such as explicitly notifying which reference signals are related, and notifying what is the relationship between these reference signals.
  • the terminal determines the configuration of these pilot relationship related parameters according to explicit configuration signaling, and then uses it for demodulation, measurement feedback, and the like. Since multiple reference signal types are involved, the number of ports of the reference signal may be many, the configuration of the port is also flexible, the relationship between the reference signals is complicated, and there are some cross relations. Therefore, if some of the above configurations are notified by explicit signaling, and sufficient flexibility is to be ensured, complicated signaling design and a large amount of signaling overhead are required.
  • the configuration of the reference signal is notified in an explicit manner, and there is still a problem: in some cases, the terminal needs to measure the reference signal of the neighboring cell, for example, in the mobility management, the terminal may It is necessary to measure the synchronization signal of the neighboring cell, the measurement pilot signal of the neighboring cell, and the like to determine whether it is necessary to switch the cell or the beam. In this manner, the serving cell needs to communicate through the interface between the cells, and then the pilot with the neighboring cell. The relevant reference signal configuration is notified to the terminal of the own cell. In fact, the inter-cell communication interface does not have to exist, and configuring the reference signal parameters of multiple neighboring cells also requires a large amount of signaling overhead. Therefore, the explicit notification method cannot be applied to all scenarios, and the letter The cost is large.

Description

参考信号发送方法及基站，配置确定方法及终端 技术领域
本公开涉及通信技术领域，尤其涉及一种参考信号的发送方法，配置的确定方法及其装置、基站和终端。
背景技术
在无线通信系统中，会存在多种不同类型的参考信号，这些参考信号分别承担着不同方面重要的作用。主要存在以下几类参考信号。
第一类是同步信号，同步信号主要用于发送端与接收端之间的同步，包括下行同步信号(Synchronization Signal，简称SS)和上行同步信号或随机接入信号(Radom access signal，简称RAS)；其中，SS可以进一步的分为主同步信号(primary synchronization signal，简称PSS)和辅同步信号(secondary synchronization signal，简称SSS)，前者主要用于基本时间间隔同步，后者用于时间间隔单元序号的对齐。
第二类是测量参考信号，又称为测量导频，主要用于接收端的测量及反馈。根据测量目的不同，可以分为移动性相关测量(RRM measurement)，波束测量(beam measurement)，信道状态信息(CSI)测量，大尺度特性(Large-scale properties)测量。主要有以下几种类型的测量导频：
下行的CSI测量导频(channel state information reference signal，简称CSI-RS)，主要用于下行的信道信息CSI测量，但也可以辅助用于波束测量，移动性测量以及大尺度特性测量；
上行的探测导频(sounding reference signal，简称SRS)，主要用于上行的信道信息CSI测量，但也可以辅助用于波束测量，移动性测量以及大尺度特性测量；
移动性测量导频(Mobility reference signal，简称MRS)，主要用于移动性相关的测量，可能是独立的信号也有可能是同步信号，广播信道的参考解调信号，或者是波束测量参考信号，以及CSI-RS信号；
波束测量导频(Beam Reference Signal，简称BRS)，主要用于波束训练，也可以用于广播信道的参考解调，移动性测量，大尺度特性测量等；
特性测量导频：用于大尺度特性测量，包括时延扩展(delay spread)、多普勒扩展(Doppler spread)、多普勒频移(Doppler shift)、平均增益和平均延迟(average gain and average delay)、频移(Frequency shift)、平均接收功率(Average received power)、接收定时(Received Timing)、信道相关性(channel correlation)、到达角(arrival angle)等特性的测量，可以是独立的导频，也可以是采用其他功能的导频增加密度来兼顾大尺度特性的测量。
第三类是参考解调信号，又称为参考解调导频，当获得信道信息后发送端可以根据信道信息进行预编码的数据/控制的传输，可以采用一层或多层的多天线传输技术。一般来说，每一层都有对应的解调参考导频(Demodulation Reference Signal，简称DMRS)，数据或控制信息要通过解调参考导频估计出的信道结合接收到的信号进行解调；主要用于参考解调包 括：
数据的参考解调导频：用于数据信道的参考解调，可以配置多个端口；包括上行数据的参考解调导频和下行的数据的参考解调导频。
控制的参考解调导频：用于控制信道的参考解调，可以配置多个端口；控制信道又可以分为专有控制信道，公有控制信道；专有/公有控制信道可能又会根据传输控制信息的不同分为多个子类，这些控制信道分别需要对应的解调导频；按照上下行区分又可以分为，上行和下行的控制的参考解调导频。
广播参考解调导频：用于广播信道的参考解调，一般只出现在下行信道中。广播信道的参考解调导频可以是独立的参考解调导频，也可以利用同步信号，或者BRS来进行参考解调。
需要特别说明的是，DMRS除了用于解调，有的情况下也可以用于CSI(Channel State Information，信道状态指示)的测量反馈。
第四类导频是相位噪声补偿参考信号(Phase Noise Compensation Reference Signal，简称PNCRS)，又称为相噪补偿导频，这一类导频一般用于相位噪声比较大时的相位补偿，也可以用于频偏的跟踪，因此也可以认为是频偏估计导频。这一类导频有的情况是单独出现，有的情况则是作为DMRS的一步分出现，主要是相位噪声的补偿主要用于数据的解调时，其也可以理解为特殊的解调导频，如果其也是定义在传输层上，每层对应一个相位噪声补充导频的端口的话，可以考虑作为DMRS的一部分。
在相关技术中，上述的参考信号的参数配置一般都是由基站确定，然后通过信令通知给终端的，常见的参考信号配置包括参考信号密度和时频位置，参考信号的端口数目，参考信号的功率等。这些配置一般采用显式信令的配置方式，也就是说直接通过信令中的状态位来指示时频位置，端口数目，功率等。除了这些参考信号配置之外，还有一些描述参考信号关系的配置信息，也需要通知给终端，如，参考信号之间的QCL(Quasi-co-location，准共位置)关系指示，类似的还有QCB(quasi-co-beam)关系指示或其他参考信号间关系指示，参考信号分组指示，参考信号的合并估计能力指示等。
可以发现上面一些配置的共同特点是，涉及了上述参考信号的相关配置都涉及了多个参考信号之间的关系指示信息，在相关技术中，参考信号参数配置主要的思路也是通过显式的控制信令来配置，如，明确地通知哪些参考信号之间存在关系，以及通知这些参考信号之间存在什么关系。终端根据显式的配置信令确定这些导频关系相关参数的配置，然后用于解调、测量反馈等。由于涉及多种参考信号类型，参考信号的端口数目可能很多，端口的配置也是灵活可变，参考信号之间的关系比较复杂，并且存在一些交叉关系。因此，如果通过显式的信令方式来通知上面的一些配置，并且要保障足够的灵活性，则需要复杂的信令设计以及大量的信令开销。
除此之外，相关技术中通过显式的方式来通知参考信号的配置，还存在一个问题：有的情况下，终端需要测量相邻小区的参考信号，如，在移动性管理时，终端可能需要测量相邻小区的同步信号、相邻小区的测量导频信号等来判断是否需要切换小区或波束，这种方式需 要服务小区通过小区间的接口进行通信，再将与相邻小区的导频相关的参考信号配置通知给本小区的终端。而实际上小区间通信接口不一定是存在的，并且配置多个相邻小区的参考信号参数也需要大量的信令开销，因此，这种显式的通知方法也不能适用于所有场景，并且信令开销大。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚明白，下文中将结合附图对本公开的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
实施例1
图1为本公开实施例的参考信号的发送方法的流程图，如图1所示，本实施例的发送方法包括以下步骤。
在步骤101，确定待发送的N个参考信号，并确定N个参考信号的参数配置。
这里的参数配置可以包括多种类型的参数，本实施例中主要关注以下一些类型的参数，包括：参考信号特性参数、参考信号发送参数、参考信号接收参数、参考信号测量参数，但本公开实施例并不排除其它方面的参数。
在步骤111，确定N个参考信号关于M类上述参数之间的关系，N、M均为正整数。
这里的关系包括相同、不相同、相关、不相关等。
在步骤121，根据N个参考信号关于M类参数的关系确定N个参考信号的发送序列；利用发送序列来表征N个参考信号关于M类参数的关系。
这些发送序列需要根据前面提到N个参考信号关于M类上述参数之间的关系来确定，N个参考信号的发送序列之间的关系能够体现N个参考信号关于M类上述参数之间存在的关系。也就是说，序列间存在的关系隐式地表征了M类参数之间的关系。
在步骤131，根据利用发送序列来表征N个参考信号关于M类参数的关系发送这N个参考信号。
下面以举例方式解释步骤101的实施方式。
在步骤101中，可以由基站确定N个参考信号，也可以由终端确定N个参考信号，二者分别对应于下行的参考信号和上行的参考信号。
可选的，这N个参考信号可以包括不同类型的参考信号和/或相同类型但不同时频资源或者不同端口资源的参考信号。
对于下行的参考信号，这里由基站确定N个参考信号，这N个参考信号可以是以下的一些情况。N个参考信号中包含一些不同类型的参考信号的例子包括：如“下行同步信号和下行测量导频信号”，“下行测量导频和下行解调导频信号”，“下行同步和下行解调导频信号”“下行相噪导频信号和下行解调导频信号”“下行相噪导频信号和下行测量导频信号”等；还包括不同子类型的参考信号，如，波束测量导频(BRS)和下行信道状态信息测量导频(CSI-RS)、下行移动性测量导频(MRS)和信道状态信息测量导频(CSI-RS)、下行控制信道解调导频和下行数据信道解调导频、广播信道解调导频和下行控制信道解调导频、下行公有控制信道解调导频和下行专有控制信道解调导频、发送寻呼消息的下行公有控制信道解调导频和发送SIB消息的下行公有控制信道解调导频。N个参考信号中一些相同类型但占用资源不同的参考信号的例子包括：如同一类型但不同端口的参考信号，例如：不同下行测量导频端口对应的导频信号；不同下行解调导频端口对应的导频信号；不同下行相噪导频端口对应的导频信号；如同一类型但不同时域位置的参考信号，例如：不同符号/子帧/时隙的下行同步信号；不同符号/子帧/时隙的下行测量导频信号；不同符号/子帧/时隙的下行解调导频信号；如同一类型但不同频域位置的参考信号，例如：不同载波/子载波/Subband(子带)/RB(Resource Block，资源块)的下行同步信号；不同载波/子载波/Subband/RB的CSI-RS信号；不同载波/子载波/Subband/RB的BRS信号；不同载波/子载波/Subband/RB的下行解调导频信号；不同载波/子载波/Subband/RB的下行相噪导频信号。N个参考信号可以包含上述一些情况或者是其结合的情况。
对于上行的参考信号，这里由终端确定N个参考信号，这N个参考信号可以是以下的一些情况。N个参考信号中包含一些不同类型的参考信号的例子包括：如“随机接入信号和测量导频信号”，“随机接入信号和解调导频信号”，“测量导频信号和解调导频信号”，“相噪导频信号和解调导频信号”“相噪导频信号和测量导频信号”等。N个参考信号中一些相同类型但占用资源不同的参考信号的例子包括：如同一类型但不同端口的参考信号，例如：不同上行测量导频端口对应的导频信号；不同上行解调导频端口对应的导频信号；不同上行相噪导频端口对应的导频信号；如同一类型但不同时域位置的参考信号，例如：不同符号/子帧/时隙的随机接入信号；不同符号/子帧/时隙的上行测量导频信号；不同符号/子帧/ 时隙的上行解调导频信号；如同一类型但不同频域位置的参考信号，例如：不同载波/子载波/Subband/RB的随机接入信号；不同载波/子载波/Subband/RB的SRS信号；不同载波/子载波/Subband/RB的上行解调导频信号；不同载波/子载波/Subband/RB的上行相噪导频信号。N个参考信号可以包含上述一些情况或者是其结合的情况。
下面来描述步骤111的实施方式。
N个参考信号的关于多类参数的关系可包括，例如：特性参数、发送参数、接收参数、合并参数、测量参数。
特性参数包括：时延扩展(delay spread)，多普勒扩展(Doppler spread)，多普勒偏移(Doppler shift)，平均增益(average gain)，平均时延(average delay)，频率偏移(Frequency shift)，平均接收功率(Average received power)接收时间(Received Timing)，信道相关性(channel correlation)，到达角(arrival angle)，离开角(Departure angle)等特性的测量。
发送参数包括：对于下行，包括：发送小区，发送扇区，发送基站，发送天线，发送节点，发送预编码，发送波束，发送功率等。
接收参数包括：对于下行，包括：接收终端，接收天线，接收权值，接收波束。
测量参数包括：用于信道测量的参数，用于干扰测量的参数。
参考信号参数的关系有几种，如，相同，不相同。
相同一般是指参数取值相同，如：密度相同，功率相同，周期相同，偏置相同等等；还可以是发送小区相同(对于下行)，发送扇区相同，发送基站相同(对于下行)，发送终端相同(对于上行)发送天线相同，发送节点相同，发送预编码相同，发送波束相同等；还可以是接收终端(对于下行)相同，接收基站(对于上行)相同，接收小区(对于上行)相同，接收天线相同，接收权值相同，接收波束相同，接收方式相同等。
不相同则指上面的这些参数取值不相同的情况。
参考信号参数的关系也可以描述为：相关，不相关。
可以是一些特性参数相关，比如频偏相同，时偏相同，到达角相同，角度扩展相同等等；也可以是一些发送参数相关，比如发送预编码，发送波束，发送功率等；也可以是一些接收参数相关，比如接收预编码，接收波束等。一般来说准共位置或准共波束是描述参考信号相关的表述形式。
相关代表的是可能完全相同，也可能是比较近似，或者有关联关系，一般来说会比相同的要求弱一些；相同是相关的一个特例。
不相关则是不同的一个特例，即不同且没有关联性；可以认为参数之间是独立的。
参考信号参数的关系也可以描述为：可合并，不可合并。
如，有一些信号是可以合并用于解调，可以合并用于相噪估计，合并用于信道测量，合并用于同步，合并用于特性测量，合并用于干扰测量等等；有一些信号则不能合并用于相噪估计，信道测量，同步，特性测量，干扰测量的。
参考信号参数的关系也可以描述为：可联合，不可联合。
合并是联合的一个特例，有些情况下，虽然不是直接合并，但由于二者有一定关联性可 以联合进行降噪来提高信道估计性能，信道测量准确性，相噪估计性能，同步性能，特性测量准确性，干扰测量准确性等。
下面描述步骤121的实施方式。
示例性而言，可以由基站或终端确定N个参考信号的发送序列。
这些发送序列的确定需要根据前面提到N个参考信号关于M类上述参数之间的关系来确定，这N个参考信号的发送序列之间的关系能够体现N个参考信号关于M类上述参数之间存在的关系；也就是说，序列间存在的关系隐式的表征了M类参数之间的关系。
比如序列属于同一集合(序列组)，则代表关于M类参数中的一类或多类参数存在关联关系；示例性而言，可以是序列属于同一序列集合，表征不同参考信号关于与该集合对应的一种或多种特性参数存在准共位置关系；序列属于同一序列集合，表征不同参考信号发送小区相同；序列属于同一序列集合，表征不同参考信号发送扇区相同；序列属于同一序列集合，表征不同参考信号发送基站相同；序列属于同一序列集合，表征不同参考信号发送终端相同；序列属于同一序列集合，表征不同参考信号发送天线相同；序列属于同一序列集合，表征不同参考信号发送节点相同；序列属于同一序列集合，表征不同参考信号发送预编码相同或相关；序列属于同一序列集合，表征不同参考信号发送波束相同或相关；序列属于同一序列集合，表征不同参考信号发送功率相同或相关；序列属于同一序列集合，表征不同参考信号接收终端相同；序列属于同一序列集合，表征不同参考信号接收基站相同；序列属于同一序列集合，表征不同参考信号接收小区相同；序列属于同一序列集合，表征不同参考信号接收扇区相同；序列属于同一序列集合，表征不同参考信号接收天线相同；序列属于同一序列集合，表征不同参考信号接收权值相同或相关；序列属于同一序列集合，表征不同参考信号接收波束相同或相关；序列属于同一序列集合，表征不同参考信号可以联合用于信道测量；序列属于同一序列集合，表征不同参考信号可以联合用于干扰测量；序列属于同一序列集合，表征不同参考信号可以联合用于相位噪声估计；序列属于同一序列集合，表征不同参考信号可以联合用于解调/相干接收；序列属于同一序列集合，表征不同参考信号可以联合用于时域/频域同步。
还可以是，利用序列相关性来表征参考信号的关系；比如序列相关系数大于约定或配置的门限则认为关于一类或多类参数相关或相同；或者是可合并，可联合。
还可以是，利用根序列索引的关系来表征参考信号的关系；比如索引满足约定的函数关系则认为关于一类或多类参数相关或相同；或者是可合并，可联合。
还可以是，利用循环移位值的关系来表征参考信号的关系；比如循环移位值相同则认为关于一类或多类参数相关或相同；或者是可合并，可联合。
还可以是，利用正交码的来表征参考信号的关系；比如正交码相同则认为关于一类或多类参数相关或相同；或者是可合并，可联合。
还可以是，利用扰码的来表征参考信号的关系；比如扰码相同则认为关于一类或多类参数相关或相同；或者是可合并，可联合。
实施例2
步骤121中，前面实施例中提到，这里发送端确定利用序列来指示不同参考信号关系的规则通常可以是收发端预先约定；或者是由发送端确定后配置给接收端；也可以是接收端确定后配置给发送端。
该规则对于不同的参考信号之间可以是不同的，以序列集合的配置为例，可以是：
为同步信号配置x个序列集合，分别为序列集合X1，X2……Xx；
为测量导频配置y个序列集合，分别为序列集合Y1，Y2……Yy；
为解调导频配置z个序列集合，分别为序列集合Z1，Z2……Zz；
也就是说，需要确定参考信号类型后，再确定上面提及理由序列来指示不同参考信号关系的规则。
另外，不同的参数其对应的规则也是不同的，以序列集合的配置为例，可以是：
为时偏参数配置a个序列集合，分别为序列集合A1，A2……Aa；
为频偏参数配置b个序列集合，分别为序列集合B1，B2……Bb；
为功率参数配置c个序列集合，分别为序列集合C1，C2……Cc；
为发送小区参数配置d个序列集合，分别为序列集合D1，D2……Dd；
为发送波束参数配置e个序列集合，分别为序列集合E1，E2……Ee；
为接收波束参数配置f个序列集合，分别为序列集合F1，F2……Ff；
为不同类型的参数配置的序列集合组可以是不同的。
与之类似的，如果是通过序列的函数关系来隐式的指示参考信号关于M类参数类型的关系，那么这些序列的函数关系对于不同类型的参考信号可以是不同的。
与之类似的，如果是通过序列的函数关系来隐式的指示参考信号关于M类参数类型的关系，那么这些序列的函数关系对于不同类型的参考信号参数可以是不同的。
本公开实施例还提供了一种计算机可读存储介质，其存储有计算机可执行指令，该计算机可执行指令被执行时实现上述参考信号的发送方法。
