一种RS生成、接收方法及终端、基站RS generation and reception method, terminal and base station
本申请要求在2017年01月25日提交中华人民共和国知识产权局、申请号为201710061322.0、发明名称为“一种RS生成、接收方法及终端、基站”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。This application claims priority to the Chinese Patent Application of the People's Republic of China Intellectual Property Office, application number 201710061322.0, and the invention name "an RS generation and reception method and terminal, base station" on January 25, 2017. This is incorporated herein by reference.
技术领域Technical field
本申请涉及移动通信技术领域,尤其涉及一种RS生成、接收方法及终端、基站。The present application relates to the field of mobile communications technologies, and in particular, to an RS generation and reception method, a terminal, and a base station.
背景技术Background technique
在长期演进(Long Term Evolution,LTE)通信中,调度的基本单位是slot(即一个时隙)。参考信号(Reference Signal,RS)的生成是采用LTE协议所定义的RS公式,例如分别有信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)、解调参考信号(Demodulation Reference Signal,DMRS)、小区参考信号(Cell-specific Reference Signal,CRS)、上行RS的跳频等的生成公式,并且,这些RS的生成公式均是均以slot编号为参数之一。In Long Term Evolution (LTE) communication, the basic unit of scheduling is a slot (ie, a time slot). The reference signal (RS) is generated by using the RS formula defined by the LTE protocol, for example, a Channel State Information Reference Signal (CSI-RS) and a Demodulation Reference Signal (DMRS). ), the cell-specific reference signal (CRS), the frequency hopping of the uplink RS, etc., and the formulas for generating these RSs are all one of the parameters of the slot number.
目前,移动通信已经发展到5G(例如,新无线(New Radio,NR)),在5G通信中,调度的时间单元不再是slot,而是其他的时间单元,比如mini-slot,其中,一个mini-slot包含比slot更少的符号数,一个slot可以划分为多个mini-slot,多个mini-slot可以共享一个RS。At present, mobile communication has been developed to 5G (for example, New Radio (NR)). In 5G communication, the scheduled time unit is no longer a slot, but other time units, such as mini-slot, one of which The mini-slot contains fewer symbols than the slot. One slot can be divided into multiple mini-slots, and multiple mini-slots can share one RS.
若直接将现有的LTE中RS的生成公式应用到5G中,将会出现如下问题:一个slot内的RS序列是相同的,这会影响干扰随机化。If the existing RS generation formula in LTE is directly applied to 5G, the following problem will occur: the RS sequences in one slot are the same, which will affect the interference randomization.
综上,目前5G通信中,还没有一种实现生成RS序列的方法。In summary, currently there is no way to implement RS sequence generation in 5G communication.
发明内容Summary of the invention
本申请提供一种RS生成、接收方法及终端、基站,用以提供一种适用于5G通信系统的RS序列的生成方式。The present application provides an RS generation and reception method, a terminal, and a base station, which are used to provide an RS sequence generation method suitable for a 5G communication system.
第一方面,本申请提供了一种RS生成方法,所述方法包括:In a first aspect, the application provides an RS generating method, where the method includes:
终端根据第一参数集,确定参考信号序列初始化值,所述第一参数集包括时间单元的编号,所述时间单元所包含的符号个数少于一个时隙slot所包含的符号个数;Determining, by the terminal, a reference signal sequence initialization value according to the first parameter set, where the first parameter set includes a number of time units, where the number of symbols included in the time unit is less than a number of symbols included in one slot;
所述终端根据所述参考信号序列初始化值,生成RS序列。The terminal generates an RS sequence according to the reference signal sequence initialization value.
本申请实施例,终端可根据第一参数集确定参考信号序列初始化值,并根据参考信号序列初始化值,生成RS序列,具体地,可应用于CSI-RS序列的生成、CRS序列的生成、DMRS序列的生成以及其他RS序列的生成,其中,第一参数集中包含的参数可参考目前现有的相应RS序列生成公式中所使用的参数,例如,针对CSI-RS序列的生成,所使用的第一参数集可参考LTE中在生成CSI-RS序列生成时所使用的公式中的参数集,但与LTE生成CSI-RS序列使用的参数集不同的是,本申请实施例中所使用的第一参数集中包含时间编号,且该时间单元所包含的符号个数是少于一个slot所包含的符号个数,而目前LTE中生成CSI-RS序列时所使用的时间单元就是slot本身,由于在5G通信或未来5G以后的通信方式中,时间单元不再使用slot,而是使用比slot所包含的符号数更少的时间单元,因此为了适应一种通信制式下能够正确地生 成RS序列,本申请实施例在生成RS序列时,是以该通信制式下的时间单元来生成RS序列,因此可保证在该通信制式下能够正确生成RS序列。In this embodiment, the terminal may determine the reference signal sequence initialization value according to the first parameter set, and generate an RS sequence according to the reference signal sequence initialization value, and specifically, may be applied to the CSI-RS sequence generation, the CRS sequence generation, and the DMRS. The generation of the sequence and the generation of other RS sequences, wherein the parameters included in the first parameter set may refer to the parameters used in the existing existing RS sequence generation formula, for example, for the generation of the CSI-RS sequence, the used A parameter set may refer to a parameter set in a formula used in generating a CSI-RS sequence in LTE, but different from a parameter set used in an LTE generated CSI-RS sequence, the first used in the embodiment of the present application The parameter set contains the time number, and the number of symbols included in the time unit is less than the number of symbols included in one slot. Currently, the time unit used in generating the CSI-RS sequence in LTE is the slot itself, due to the 5G. In the communication or communication mode after 5G, the time unit no longer uses the slot, but uses less time units than the number of symbols included in the slot, so in order to adapt Planted communications standards can be accurately generating the RS sequence, application of the present embodiment when generating the RS sequence, in a time unit in the communication standard RS sequence is generated, thus guaranteeing the correct RS sequence can be generated at the communications standard.
结合第一方面,在第一方面的第一种可能的实现方式中,所述时间单元的编号是根据包含RS时域位置的一个时间单元的编号确定,或者,根据共享同一RS时域位置的至少两个时间单元编号确定。With reference to the first aspect, in a first possible implementation manner of the first aspect, the number of the time unit is determined according to a number of a time unit that includes the location of the RS time domain, or according to the location of the same RS time domain. At least two time unit numbers are determined.
在一种通信制式下,一个RS时域位置可能是由一个时间单元独占,也可能是由多个时间单元共享,当每个时间单元独立对应一个RS时域位置时,则本申请实施例中的第一参数集中的时间单元编号就等于包含RS时域位置的时间单元的编号;当多个时间单元(至少两个)共享一个RS时域位置时,则第一参数集中的时间单元编号可根据多个时间单元编号来确定。In a communication system, an RS time domain location may be exclusive to one time unit, or may be shared by multiple time units. When each time unit independently corresponds to one RS time domain location, in this embodiment of the present application, The time unit number in the first parameter set is equal to the number of the time unit including the RS time domain position; when multiple time units (at least two) share one RS time domain position, the time unit number in the first parameter set may be Determined based on multiple time unit numbers.
结合第一方面的第一种可能的实现方式,在第一方面的第二种可能的实现方式中,所述时间单元的编号根据共享同一RS时域位置的至少两个时间单元编号确定,包括:所述时间单元的编号等于所述至少两个时间单元编号中最小的时间单元编号,或者,所述时间单元的编号等于所述至少两个时间单元编号中最大的时间单元编号。With reference to the first possible implementation manner of the first aspect, in a second possible implementation manner of the first aspect, the number of the time unit is determined according to at least two time unit numbers that share the same RS time domain location, including The number of the time unit is equal to the smallest time unit number of the at least two time unit numbers, or the number of the time unit is equal to the largest time unit number of the at least two time unit numbers.
当有多个时间单元共享同一RS时域位置时,确定第一参数集中的时间单元编号的方法有很多种可以选择,举例来说,以mini-slot表示本申请实施例中的时间单元,以表示本申请实施例中第一参数集中的时间单元的编号,则n s=min(mini-slot#),其中,mini-slot#表示共享同一RS时域位置的所有时间单元的编号所构成的集合,或者是n s=max(mini-slot#),或者还可以是n s=min(mini-slot#odd+1,mini-slot#even),或者还可以是n s=max(mini-slot#odd+1,mini-slot#even),或者还可以是n s=min(mini-slot#odd,mini-slot#even+1),或者还可以是n s=max(mini-slot#odd+1,mini-slot#even+1),或者还可以是n s=min(mini-slot#odd-1,mini-slot#even),或者还可以是n s=max(mini-slot#odd-1,mini-slot#even),其中,mini-slot#odd表示时间单元的奇数编号的集合,mini-slot#odd+1表示将时间单元的奇数编号的集合中的每个时间单元的奇数编号加1,类似地,mini-slot#even表示时间单元的偶数编号的集合,mini-slot#even+1表示将时间单元的偶数编号的集合中的每个时间单元的偶数编号加1,举个例子,以n s=min(mini-slot#odd+1,mini-slot#even)公式为例,假设当前共享同一RS时域位置的时间单元分别有时间单元0、时间单元1、时间单元2、时间单元3,则mini-slot#odd={1,3},mini-slot#even={0,2},因而,n s=min(2,4,0,2)=0,对于其他公式,计算方式类似,此处不再赘述,并且,本申请实施例中对于根据共享同一RS时域位置的多个时间单元的编号得到第一参数集中的事件单元编号的方法并不限于上述几种方式,以上只是作为举例说明,任何可以根据共享同一RS时域位置的多个时间单元的编号得到第一参数集中的时间单元编号的方法都可用于本申请实施例。 When there are multiple time units sharing the same RS time domain location, there are many methods for determining the time unit number in the first parameter set. For example, the time unit in the embodiment of the present application is represented by a mini-slot. Indicates the number of the time unit in the first parameter set in the embodiment of the present application, then n s =min(mini-slot#), where mini-slot# represents the number of all time units sharing the same RS time domain location. The set, either n s =max(mini-slot#), or n s =min(mini-slot#odd+1,mini-slot#even), or n s =max(mini- Slot#odd+1, mini-slot#even), or it can be n s =min(mini-slot#odd,mini-slot#even+1), or it can be n s =max(mini-slot# Odd+1, mini-slot#even+1), or it can be n s =min(mini-slot#odd-1,mini-slot#even), or it can be n s =max(mini-slot# Odd-1, mini-slot#even), where mini-slot#odd represents the set of odd-numbered time units, and mini-slot#odd+1 represents each time unit in the set of odd-numbered time units odd number The number is incremented by 1. Similarly, mini-slot#even represents a set of even-numbered time units, and mini-slot#even+1 represents an even number of each time unit in the set of even-numbered time units plus one. For example, taking n s =min(mini-slot#odd+1, mini-slot#even) as an example, assume that the time units currently sharing the same RS time domain location have time unit 0, time unit 1, and time unit, respectively. 2, time unit 3, then mini-slot#odd={1,3}, mini-slot#even={0,2}, thus, n s =min(2,4,0,2)=0, for For other formulas, the calculation manner is similar, and is not described here again. Moreover, the method for obtaining the event unit number in the first parameter set according to the number of multiple time units sharing the same RS time domain position in the embodiment of the present application is not limited to the above. In several ways, the above is only an example. Any method that can obtain the time unit number in the first parameter set according to the number of multiple time units sharing the same RS time domain location can be used in the embodiment of the present application.
结合第一方面,在第一方面的第三种可能的实现方式中,,所述终端从基站接收信令,所述信令包括用于指示所述时间单元的编号n s的信息。 In conjunction with the first aspect, in a third possible implementation manner of the first aspect, the terminal receives signaling from a base station, where the signaling includes information indicating a number n s of the time unit.
如此,则终端直接通过接收基站下发的信令,该信令中包含有终端所使用的第一参数集中的时间单元编号,其中,信令可以是无线资源控制(Radio Resource Control,RRC)、下行控制信息(Downlink Control Information,DCI)信令配置。例如信令中携带有一个参数RSgeneratorSlotnumber及该参数对应的具体数值,该数值用于表示时间单元的编号,比如该数值的取值范围为0~59中任一整数,59为一个示例,表示LTE 中slot编号0~19(在一个无线帧内),若一个slot包含3个时间单元,则一共有60个时间单元,若基站通过信令指示一个具体的编号,例如指示RSgeneratorSlotnumber=20,则第一参数集中的时间单元编号=20。从而,基站下发信令后,终端就知道了某个mini-slot上的RS生成所使用的n s的取值是什么。 In this manner, the terminal directly receives the signaling sent by the base station, where the signaling includes the time unit number in the first parameter set used by the terminal, where the signaling may be Radio Resource Control (RRC), Downlink Control Information (DCI) signaling configuration. For example, the signaling carries a parameter RSgeneratorSlotnumber and a specific value corresponding to the parameter. The value is used to indicate the number of the time unit. For example, the value ranges from 0 to 59, and 59 is an example, indicating LTE. The slot number is 0 to 19 (in a radio frame). If a slot contains 3 time units, there are 60 time units. If the base station indicates a specific number by signaling, for example, indicating RSgeneratorSlotnumber=20, then The time unit number in a parameter set = 20. Therefore, after the base station sends signaling, the terminal knows what the value of n s used for RS generation on a mini-slot is.
结合第一方面的第一种可能的实现方式或第一方面的第二种可能的实现方式,在第一方面的第四种可能的实现方式中,,所述终端从基站接收信令,所述信令包括指示共享同一RS时域位置的至少两个时间单元编号的信息。With reference to the first possible implementation of the first aspect or the second possible implementation of the first aspect, in a fourth possible implementation manner of the first aspect, the terminal receives signaling from a base station, where The signaling includes information indicating at least two time unit numbers sharing the same RS time domain location.
如此,终端根据接收到的信令,可得知哪些时间单元共享同一RS时域位置,进而根据这些时间单元的编号确定出第一参数集中的时间单元的编号,例如,基站下发给终端的信令中携带有时间单元的编号,例如为(0,1,2,3),则终端接收到该信令后,从中获取时间单元的编号0,1,2,3,然后通过运算,得到第一参数集中的时间单元的编号的参数取值,具体地计算方法,参考上述说明,此处不再赘述。In this manner, the terminal can learn, according to the received signaling, which time units share the same RS time domain location, and then determine the number of the time unit in the first parameter set according to the number of the time units, for example, the base station sends the same to the terminal. The signaling carries the number of the time unit, for example, (0, 1, 2, 3). After receiving the signaling, the terminal obtains the number 0, 1, 2, and 3 of the time unit, and then obtains the operation result. The parameter value of the number of the time unit in the first parameter set, and the specific calculation method, refer to the above description, and details are not described herein again.

为了使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请作进一步地详细描述。In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the accompanying drawings.

Hereinafter, some of the terms in the present application will be explained to be understood by those skilled in the art.
1)、终端,又称之为用户设备(User Equipment,UE),是一种向用户提供语音和/或数据连通性的设备,例如,具有无线连接功能的手持式设备、车载设备等。常见的终端例如包括:手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device,MID)、可穿戴设备,例如智能手表、智能手环、计步器等。1) A terminal, also called a User Equipment (UE), is a device that provides voice and/or data connectivity to a user, for example, a handheld device with a wireless connection function, an in-vehicle device, and the like. Common terminals include, for example, mobile phones, tablets, notebook computers, PDAs, mobile internet devices (MIDs), wearable devices such as smart watches, smart bracelets, pedometers, and the like.

In addition, a Wifi Access Point (AP) or the like may also be included.
在4G(第四代移动通信系统)通信系统中,RS序列均是根据slot编号生成的,例如,针对用于指示下行信道状态信息的参考信号,例如下行信道状态信息参考信号(channel state information reference signal,CSI-RS)的生成公式为:In a 4G (fourth generation mobile communication system) communication system, RS sequences are all generated according to a slot number, for example, for a reference signal for indicating downlink channel state information, such as a channel state information reference (channel state information reference) The formula for generating signal, CSI-RS) is:

其中,
Figure PCTCN2018074199-appb-000002
为参考信号序列值,即RS序列,n s为无线帧的slot编号,m为参考信号映射的资源块(Resource Block,RB)序号,l为符号编号,
Figure PCTCN2018074199-appb-000003
为下行最大资源块(Resource Block,RB)数,c()为协议定义的参考信号初始化函数(例如为伪随机数生成函数或者是非伪随机数生成函数等),c init为c()函数的初始化值,称为参考信号初始化值,并且:
among them,
Figure PCTCN2018074199-appb-000002
For the reference signal sequence value, that is, the RS sequence, n s is the slot number of the radio frame, m is the resource block (RB) number of the reference signal mapping, and l is the symbol number.
Figure PCTCN2018074199-appb-000003
For the number of downlink maximum resource blocks (RBs), c() is a reference signal initialization function defined by the protocol (for example, a pseudo-random number generation function or a non-pseudo-random number generation function, etc.), and c init is a c() function. The initialization value, called the reference signal initialization value, and:

Figure PCTCN2018074199-appb-000004
其中,n’ s为与slot编号有关的参考,是根据slot编号计算得到的,具体地, Where n' s is a reference related to the slot number, which is calculated according to the slot number, specifically,
Figure PCTCN2018074199-appb-000005
Figure PCTCN2018074199-appb-000005
其中,对于帧结构类型3(授权辅助接入(licensed-assisted access,LAA)中使用正常循环前缀的辅助小区),n’ s使用上面的取值,否则使用下面的取值。 For the frame structure type 3 (the auxiliary cell using the normal cyclic prefix in the licensed-assisted access (LAA)), n 's uses the above values, otherwise the following values are used.
Figure PCTCN2018074199-appb-000006
Figure PCTCN2018074199-appb-000006
以及,N CP为循环前缀(cylic prefix,CP)标识,

And, N CP is a cylic prefix (CP) identifier,
Figure PCTCN2018074199-appb-000007
The value configured for the base station through high layer signaling. The default value is the cell identifier (ID).
从上述公式中可看出,c init是根据n s,即slot编号得到的,从而使得RS序列
Figure PCTCN2018074199-appb-000008
也是根据slot编号得到的,但是在5G中,对于时间单元,已经不再使用slot,而是使用包含比slot更少的符号数的时间单元,具体可称之为mini-slot,例如,一个mini-slot包含的符号数为2个、4个等,而一个slot包含的符号数为7个或14个,因此mini-slot包含的符号数是是少于slot包含的符号数,并且,在一个无线帧中可以只包含一种类型的mini-slot,也可以是多种类型的mini-slot的混合。
As can be seen from the above formula, c init is obtained according to n s , that is, the slot number, thereby making the RS sequence
Figure PCTCN2018074199-appb-000008
It is also based on the slot number, but in 5G, for the time unit, the slot is no longer used, but a time unit containing fewer symbols than the slot, specifically called a mini-slot, for example, a mini -slot contains 2, 4, etc., and a slot contains 7 or 14 symbols, so the number of symbols contained in the mini-slot is less than the number of symbols contained in the slot, and, in one A wireless frame can contain only one type of mini-slot or a mixture of multiple types of mini-slots.
再比如,针对用于指示下行小区的参考信号,例如下行小区参考信号(cell-specific reference signal,CRS)的生成公式为:For another example, for a reference signal used to indicate a downlink cell, for example, a generation criterion of a cell-specific reference signal (CRS) is:

Figure PCTCN2018074199-appb-000014
For the downlink RB number, c() is the reference signal initialization function defined by the protocol (for example, a pseudo random number generation function or a non-pseudo random number generation function, etc.), and c init is an initialization value of the c() function, which is called reference signal initialization. Value, N CP is the CP logo,

再比如,针对用于下行解调的参考信号,例如下行解调参考信号(demodulation reference signal,DMRS)的生成公式为:For another example, for a reference signal used for downlink demodulation, for example, a downlink demodulation reference signal (DMRS) is generated as:

Figure PCTCN2018074199-appb-000020
For the bandwidth corresponding to the RB block determined according to the downlink shared physical channel (PDSCH) transmission, c() is a reference signal initialization function defined by the protocol (for example, a pseudo random number generation function or a non-pseudo random number generation) Function, etc.), c init is the initialization value of the c() function, called the reference signal initialization value.

从上述公式中可看出,c init是根据n s,即slot编号得到的,从而使得RS序列
Figure PCTCN2018074199-appb-000029
也是根据slot编号得到的。特别的,DMRS的参考信号初始化值的计算公式中,slot编号除以2并向下取整,目的是为了在相邻slot上生成一样的RS序列,以便使用正交覆盖码(Orthogonal Cover Code,OCC)使相邻slot上的RS保持正交性。
As can be seen from the above formula, c init is obtained according to n s , that is, the slot number, thereby making the RS sequence
Figure PCTCN2018074199-appb-000029
It is also based on the slot number. In particular, in the calculation formula of the reference signal initialization value of the DMRS, the slot number is divided by 2 and rounded down, in order to generate the same RS sequence on the adjacent slot, so as to use the orthogonal cover code (Orthogonal Cover Code, OCC) keeps the RSs on adjacent slots orthogonal.
再比如,上行的RS序列是基于ZC序列(Zadoff-Chu序列)生成的,ZC序列的生成在LTE协议中不依赖于slot编号。但是基于ZC序列所生成的上行RS进行跳频或映射时,其跳频或映射是与slot编号有关的,如下生成公式:For another example, the uplink RS sequence is generated based on a ZC sequence (Zadoff-Chu sequence), and the generation of the ZC sequence does not depend on the slot number in the LTE protocol. However, when the uplink RS generated by the ZC sequence is frequency hopping or mapped, the frequency hopping or mapping is related to the slot number, and the following formula is generated:
u=(f gh(n s)+f ss)mod30, u=(f gh (n s )+f ss )mod30,
其中,u表示序列组数字,f gh(n s)表示组跳频图样,f ss表示序列移位图样。 Where u denotes a sequence group number, f gh (n s ) denotes a group hopping pattern, and f ss denotes a sequence shift pattern.
并且,

and,

其中,c()表示伪随机序列,i是从0到7的整数取值,gh表示组跳(group hopping),n s表示slot的编号。 Where c() represents a pseudo-random sequence, i is an integer value from 0 to 7, gh represents group hopping, and n s represents the number of the slot.
综上,可看出,现有技术中的RS生成公式采用LTE协议中所定义的RS公式,不管是下行CSI-RS生成公式、DMRS生成公式、CRS生成公式等,还是上行序列映射,均是以slot编号为参数之一。In summary, it can be seen that the RS generation formula in the prior art adopts the RS formula defined in the LTE protocol, whether it is a downlink CSI-RS generation formula, a DMRS generation formula, a CRS generation formula, or an uplink sequence mapping, Use the slot number as one of the parameters.
随着通信技术的发展,目前5G通信中将slot划分为更小的时间单元,本申请实施例中统一称为mini-slot,由于mini-slot是比slot更小的单位,因此若对上述各生成RS的公式不加以更改而直接使用的话,将会导致位于同一slot的多个mini-slot所对应的RS序列是相同的,因此影响干扰的随机化。With the development of the communication technology, the slot is divided into smaller time units in the current 5G communication, which is collectively referred to as a mini-slot in the embodiment of the present application, and since the mini-slot is a smaller unit than the slot, If the formula for generating RS is used without change, the RS sequence corresponding to multiple mini-slots in the same slot will be the same, thus affecting the randomization of interference.
为此,为本申请实施例提供一种RS生成方法,如图1所示,该方法由终端侧执行,具体包括:To this end, an RS generation method is provided in the embodiment of the present application. As shown in FIG. 1 , the method is performed by the terminal side, and specifically includes:
步骤101、终端根据第一参数集,确定参考信号序列初始化值,所述第一参数集包括时间单元的编号,所述时间单元所包含的符号个数少于一个时隙slot所包含的符号个数。Step 101: The terminal determines, according to the first parameter set, a reference signal sequence initialization value, where the first parameter set includes a number of time units, where the number of symbols included in the time unit is less than a symbol included in a time slot. number.
步骤102、终端根据所述参考信号序列初始化值,生成RS序列。Step 102: The terminal generates an RS sequence according to the initialization value of the reference signal sequence.
为方便理解,下面结合具体的例子进行说明,以CSI-RS的生成公式为例,则第一参考集包含

n RNTI,以及还包括时间单元的编号,本申请实施例中仍然以n s表示,对于其他RS序列的生成公式,则第一参数集相应地为其他参数的集合,但不管是何种公式生成RS,所使用的第一参数集中均包含时间单元的编号这个参数。
For convenience of understanding, the following describes a specific example. Taking the CSI-RS generation formula as an example, the first reference set includes
Figure PCTCN2018074199-appb-000031
n RNTI , and the number of the time unit, which is still represented by n s in the embodiment of the present application. For the generation formula of other RS sequences, the first parameter set is correspondingly a set of other parameters, but no matter what formula is generated RS, the first parameter set used contains the parameter of the time unit number.
因此,在申请实施例中,以CSI-RS的生成公式为例,为得到RS序列,仍然是需要计算得到第一参数集中的参数取值,进而求得参考信号序列初始化值,但与现有技术的区别在于,所使用的参数的求取方式改变了,例如,以时间单元的编号这个参数为例,其求取方式不再是使用slot的编号作为参数n s的取值,而是根据时间单元的编号来求得。 Therefore, in the application embodiment, taking the generation formula of the CSI-RS as an example, in order to obtain the RS sequence, it is still necessary to calculate the value of the parameter in the first parameter set, and then obtain the reference signal sequence initialization value, but with the existing The technical difference is that the method of obtaining the parameters is changed. For example, taking the parameter of the time unit number as an example, the method of obtaining is no longer using the slot number as the value of the parameter n s , but according to The number of time units is obtained.
为方便说明,本申请实施例中将使用mini-slot来表示本申请实施例所适用的时间单元。For convenience of description, the mini-slot will be used in the embodiment of the present application to indicate the time unit to which the embodiment of the present application applies.
其中,参考信号序列初始化值在具体地实现方式中,即为上述公式中出现的c init的计算方式,当然,c init并的计算不限于上述几种形式,其它关于c init的计算方式也包含在本申请的保护范围内。 Wherein, the reference signal sequence initialization value is in a specific implementation manner, that is, the calculation method of c init appearing in the above formula. Of course, the calculation of c init is not limited to the above several forms, and other calculation methods for c init also include Within the scope of protection of this application.
下面结合附图说明如何确定第一参数集中的时间单元的编号,即如何确定各RS序列生成公式中的n s值。 The following describes how to determine the number of time units in the first parameter set, that is, how to determine the value of n s in each RS sequence generation formula.
当每个mini-slot占用一个RS时域位置时,则n s的取值即为一个mini-slot的编号。其中,该mini-slot的编号可由基站通过信令的方式告知终端,例如在信令中携带一个包含mini-slot的编号的参数,信令中携带有一个参数RSgeneratorSlotnumber及该参数对应的具体数值,该数值用于表示时间单元的编号,比如该数值的取值范围为0~59中任一整数,59为一个示例,表示LTE中slot编号0~19(在一个无线帧内),若一个slot包含3个时间单元,则一共有60个时间单元(mini-slot),若基站通过信令指示一个具体的编号,例如指示RSgeneratorSlotnumber=20,则第一参数集中的时间单元编号=20,即n s=20。 When each mini-slot occupies an RS time domain location, the value of n s is the number of a mini-slot. The number of the mini-slot may be notified to the terminal by the base station by means of signaling, for example, the signaling carries a parameter containing the number of the mini-slot, and the signaling carries a parameter RSgeneratorSlotnumber and a specific value corresponding to the parameter. The value is used to indicate the number of the time unit. For example, the value ranges from 0 to 59, and 59 is an example. The slot numbers in the LTE are 0 to 19 (in a radio frame). If a slot is used. If there are 3 time units, there are 60 time units (mini-slots). If the base station indicates a specific number by signaling, for example, indicating that RSgeneratorSlotnumber=20, the time unit number in the first parameter set is 20, that is, n. s = 20.
当多个mini-slot共享同一个RS时域位置时,则可以通过协议预定义的方式,指示哪些mini-slot共享一个RS时域位置,从而终端可以根据共享同一RS时域位置的多个mini-slot的编号计算得到n s的取值;或者是共享一个RS时域位置的多个mini-slot的编号是由基站通过下令下发至终端,从而终端根据接收到的多个mini-slot的编号计算得到n s的取值。 When multiple mini-slots share the same RS time domain location, it is possible to indicate which mini-slots share an RS time domain location in a protocol pre-defined manner, so that the terminal can share multiple minis according to the same RS time domain location. The number of the -slot is calculated to obtain the value of n s ; or the number of the multiple mini-slots sharing the location of one RS time domain is sent by the base station to the terminal, so that the terminal is based on the received multiple mini-slots. The number is calculated to get the value of n s .
其中,信令可以是无线资源控制(Radio Resource Control,RRC)、下行控制信息(Downlink Control Information,DCI)、MAC控制元素(Media Access Control control element,MAC CE)信令等,当然,也可以是其他信令,本申请实施例对此不作限定。The signaling may be a radio resource control (RRC), a downlink control information (DCI), a MAC control (MAC CE) signaling, etc., of course, Other signalings are not limited in this embodiment of the present application.
如图2所示,为本申请实施例提供的一种可能的时间单元(mini-slot)示意图,其中,示例为每个mini-slot包含4个符号,且mini-slot#0与mini-slot#1共享一个RS时域位置,mini-slot#2和mini-slot#3共享一个RS时域位置,则终端在生成RS序列时,使用到的时间单元的编号这个参数可以是根据共享该RS时域位置的时间单元的编号来确定,并且,共享同一RS时域位置的时间单元的编号可以是协议预定义或基站通过信令下发,以mini-slot#0与mini-slot#1共享一个RS时域位置为例,则mini-slot#0与mini-slot#1可以是基站通过信令下发或者协议预定义,当mini-slot#0与mini-slot#1是终端从接收的信令中获得时,在获得信令后,从中获取mini-slot#0与mini-slot#1,并进一步通过运算得到第一参数集中的时间单元的编号这个参数(即n s)。 FIG. 2 is a schematic diagram of a possible mini-slot provided by an embodiment of the present application, where an example is that each mini-slot includes 4 symbols, and mini-slot#0 and mini-slot. #1 shares an RS time domain location, mini-slot#2 and mini-slot#3 share an RS time domain location, and the terminal uses the time unit number when generating the RS sequence. This parameter may be based on sharing the RS. The number of the time unit of the time domain location is determined, and the number of the time unit sharing the same RS time domain location may be a protocol pre-defined or the base station is sent by signaling, and is shared by mini-slot#0 and mini-slot#1. For example, if an RS time domain location is used, the mini-slot#0 and mini-slot#1 may be sent by the base station through signaling or protocol pre-defined, when mini-slot#0 and mini-slot#1 are received by the terminal. When the signaling is obtained, after obtaining the signaling, the mini-slot#0 and the mini-slot#1 are obtained therefrom, and the parameter of the time unit number in the first parameter set (ie, n s ) is further obtained by the operation.
具体地计算方法有很多种,本申请实施例不做限定,例如可以是n s=min(mini-slot#), 其中,mini-slot#表示共享同一RS时域位置的所有时间单元的编号所构成的集合,或者是n s=max(mini-slot#),或者还可以是n s=min(mini-slot#odd+1,mini-slot#even),或者还可以是n s=max(mini-slot#odd+1,mini-slot#even),或者还可以是n s=min(mini-slot#odd,mini-slot#even+1),或者还可以是n s=max(mini-slot#odd+1,mini-slot#even+1),或者还可以是n s=min(mini-slot#odd-1,mini-slot#even),或者还可以是n s=max(mini-slot#odd-1,mini-slot#even),其中,mini-slot#odd表示时间单元的奇数编号的集合,mini-slot#odd+1表示将时间单元的奇数编号的集合中的每个时间单元的奇数编号加1,同样地,mini-slot#even表示时间单元的偶数编号的集合,mini-slot#even+1表示将时间单元的偶数编号的集合中的每个时间单元的偶数编号加1,举个例子,以n s=min(mini-slot#odd+1,mini-slot#even)公式为例,假设当前共享同一RS时域位置的时间单元分别有时间单元0、时间单元1、时间单元2、时间单元3,则mini-slot#odd={1,3},mini-slot#even={0,2},因而,n s=min(2,4,0,2)=0,对于其他公式,计算方式类似,此处不再赘述,并且,本申请实施例中对于根据共享同一RS时域位置的多个时间单元的编号得到第一参数集中的事件单元编号的方法并不限于上述几种方式,以上只是作为举例说明,任何可以根据共享同一RS时域位置的多个时间单元的编号得到第一参数集中的事件单元编号的方法都可用于本申请实施例。 Specifically, there are many calculation methods, which are not limited in the embodiment of the present application, and may be, for example, n s =min(mini-slot#), where mini-slot# indicates the number of all time units sharing the same RS time domain location. The set of constituents, either n s =max(mini-slot#), or n s =min(mini-slot#odd+1,mini-slot#even), or n s =max( Mini-slot#odd+1, mini-slot#even), or it can be n s =min(mini-slot#odd,mini-slot#even+1), or it can be n s =max(mini- Slot#odd+1, mini-slot#even+1), or it can be n s =min(mini-slot#odd-1,mini-slot#even), or it can be n s =max(mini- Slot#odd-1, mini-slot#even), where mini-slot#odd represents the set of odd-numbered time units, mini-slot#odd+1 represents each time in the set of odd-numbered time units The odd number of the unit is incremented by 1. Similarly, mini-slot#even represents the set of even numbers of time units, and mini-slot#even+1 represents the even number of each time unit in the set of even numbers of time units. 1, for example To n s = min (mini-slot # odd + 1, mini-slot # even) Equation an example, assume that the current RS share the same temporal position of the time units each time unit 0, unit 1 time, 2 time units, Time unit 3, then mini-slot#odd={1,3}, mini-slot#even={0,2}, thus, n s =min(2,4,0,2)=0, for other formulas The calculation method is similar, and is not described here again. Moreover, the method for obtaining the event unit number in the first parameter set according to the number of multiple time units sharing the same RS time domain location in the embodiment of the present application is not limited to the foregoing. The foregoing is only an example. Any method that can obtain the event unit number in the first parameter set according to the number of multiple time units sharing the same RS time domain location can be used in the embodiment of the present application.
在一种可能的设计中,考虑到现有协议为了使相邻slot上的RS一致使用正交覆盖码(orthogonal cover code,OCC),因此在计算RS序列时,使用到的公式中还对时间单元的编号参数进行相应处理,例如,对时间单元的编号除以2之后再向下取整,从而可保证相邻两个slot可生成相同的RS序列。In a possible design, considering the existing protocol, in order to make the RS on the adjacent slot use the orthogonal cover code (OCC), the formula used in calculating the RS sequence is also time-dependent. The numbering parameters of the unit are processed accordingly. For example, the number of the time unit is divided by 2 and then rounded down to ensure that the adjacent two slots can generate the same RS sequence.
以现有协议的DMRS生成公式为例,可以看出,对于参数信号序列初始化值的计算公式为:Taking the DMRS generation formula of the existing protocol as an example, it can be seen that the calculation formula for the initialization value of the parameter signal sequence is:
Figure PCTCN2018074199-appb-000032
Figure PCTCN2018074199-appb-000032
其中,对n s进行了除以2并向下取整的处理。 Among them, n s is divided by 2 and rounded down.
为了延续对OCC的使用,本申请实施例可对上述公式根据mini-slot共享RS时域位置的具体情况,对上述公式做适当修改。In order to continue the use of the OCC, the embodiment of the present application may appropriately modify the above formula according to the specific situation of the mini-slot sharing RS time domain location.
举例来说,以图2所示的共享情形为例,为了图2中mini-slot#0、mini-slot#1所共享的一个符号的RS与mini-slot#2、mini-slot#3所共享的一个符号的RS相同,则可将上述关于下行DMRS计算公式中的

修改为
Figure PCTCN2018074199-appb-000034
同理,如果图2所示的每个mini-slot的长度缩减到2个符号,即8个mini-slot共享2个符号的RS,公式可以修改为
Figure PCTCN2018074199-appb-000035
For example, taking the sharing situation shown in FIG. 2 as an example, for the symbol RS and mini-slot#2 and mini-slot#3 shared by mini-slot#0 and mini-slot#1 in FIG. If the shared RS of one symbol is the same, then the above calculation formula in the downlink DMRS can be used.

Similarly, if the length of each mini-slot shown in Figure 2 is reduced to 2 symbols, that is, 8 mini-slots share 2 symbols of RS, the formula can be modified to

因此,DMRS生成公式中的生成参考信息序列初始化值时,可将

修改为
Figure PCTCN2018074199-appb-000037
其中M等于一个或多个时隙内共享RS序列的时间单元的个数,即M与numerology(用于指示mini-slot的编号)有关。numerology中包含了mini-slot的长度。此方案的前提是沿用了LTE中DMRS的设计思路(相邻slot上的RS一致,并使用OCC)
Therefore, when generating the initialization value of the reference information sequence in the DMRS generation formula,
Figure PCTCN2018074199-appb-000036
change into
Figure PCTCN2018074199-appb-000037
Where M is equal to the number of time units sharing the RS sequence in one or more time slots, ie M is related to the numerology (used to indicate the number of the mini-slot). The length of the mini-slot is included in the numerology. The premise of this scheme is to follow the design idea of DMRS in LTE (RS is consistent on adjacent slots and OCC is used)
举例:指示4符号mini-slot(如通过信令指示mini-slot的符号数,或者,通过numerology可确定mini-slot的符号数),终端和基站可以对应出M=4并生成一致的DMRS用于UE解调。For example, the 4-symbol mini-slot is indicated (for example, the number of symbols of the mini-slot is indicated by signaling, or the number of symbols of the mini-slot can be determined by numerology), and the terminal and the base station can correspond to M=4 and generate a consistent DMRS. Demodulated at the UE.
指示numerology为2符号mini-slot,终端和基站可以对应出M=8。即M的取值是与mini-slot包含的符号个数有关。Indicates that the numerology is a 2-symbol mini-slot, and the terminal and the base station can correspond to M=8. That is, the value of M is related to the number of symbols included in the mini-slot.
因而,在上述例子中,则第一参数集中不仅包含有时间单元的编号,更进一步地, 还包括一个或多个时隙内共享RS序列的时间单元的个数,即上述所述的M的取值。具体地,M等于共享RS序列的时间单元的个数。其中,多个时隙共享RS序列时,这多个时隙可以为连续的多个时隙,也可以是不连续的多个时隙。例如,连续的多个时隙可以为两个连续的时隙,不连续的多个时隙是编号不连续的多个时隙。不连续的多个时隙也可以共享RS序列,例如,时隙1和3共享了位于时隙1上的RS序列等。Therefore, in the above example, the first parameter set includes not only the number of the time unit, but further, the number of time units sharing the RS sequence in one or more time slots, that is, the M described above. Value. Specifically, M is equal to the number of time units sharing the RS sequence. When multiple time slots share an RS sequence, the multiple time slots may be consecutive multiple time slots, or may be multiple consecutive time slots. For example, a plurality of consecutive time slots may be two consecutive time slots, and a plurality of consecutive time slots are a plurality of time slots numbered discontinuous. A plurality of slots that are not consecutive may also share an RS sequence, for example, slots 1 and 3 share an RS sequence located on slot 1 and the like.
另一个对DMRS设计的方案为不使用OCC,因此不需要相邻slot的RS一致。可以借鉴CSI-RS的计算公式,即n s’与n s为线性关系,即DMRS的计算公式可以由: Another solution for DMRS design is to not use OCC, so there is no need for RS alignment of adjacent slots. Can learn from the CSI-RS calculation formula, that is, n s ' and n s are linear, that is, the calculation formula of DMRS can be:

需要说明的是,上述实施例只是以DMRS的生成为例进行说明,对于其他需要使用OCC或者不使用OCC的RS序列的生成,本申请实施例同样适用,对此不做限定。It should be noted that the foregoing embodiment is only described by taking the generation of the DMRS as an example. For other generations of the RS sequence that requires the use of the OCC or the OCC, the embodiment of the present application is also applicable, and is not limited thereto.
以上是对终端侧如何生成RS序列进行说明,而对于基站侧,也可以是使用同样地方法生成RS序列,下面进行说明。The above description is for how to generate the RS sequence on the terminal side, and the base station side may generate the RS sequence by the same method, which will be described below.
参考图3,为本申请实施例提供的RS生成方法示意图,该方法执行主体为基站,包括:Referring to FIG. 3, it is a schematic diagram of a method for generating an RS according to an embodiment of the present disclosure.
步骤301、基站根据第一参数集,确定参考信号序列初始化值,所述第一参数集包括时间单元编号,所述时间单元所包含的符号个数少于一个时隙slot所包含的符号个数;Step 301: The base station determines, according to the first parameter set, a reference signal sequence initialization value, where the first parameter set includes a time unit number, where the number of symbols included in the time unit is less than the number of symbols included in one slot. ;
步骤302、基站根据所述参考信号序列初始化值,生成RS序列。Step 302: The base station generates an RS sequence according to the initialization value of the reference signal sequence.
进一步地,所述时间单元的编号是根据包含RS时域位置的一个时间单元的编号确定,或者,根据共享同一RS时域位置的至少两个时间单元编号确定。Further, the number of the time unit is determined according to the number of a time unit including the RS time domain location, or is determined according to at least two time unit numbers sharing the same RS time domain location.
进一步地,所述时间单元的编号根据共享同一RS时域位置的至少两个时间单元编号确定,包括:Further, the number of the time unit is determined according to at least two time unit numbers sharing the same RS time domain location, including:
所述时间单元的编号等于所述至少两个时间单元编号中最小的时间单元编号,或者,所述时间单元的编号等于所述至少两个时间单元编号中最大的时间单元编号。The number of the time unit is equal to the smallest time unit number of the at least two time unit numbers, or the number of the time unit is equal to the largest time unit number of the at least two time unit numbers.
进一步地,所述第一参数集还包括一个或多个时隙内共享RS序列的时间单元的个数。Further, the first parameter set further includes a number of time units sharing the RS sequence in one or more time slots.
从上述步骤可看出,基站侧生成RS序列的方法与终端侧相同,此处不再赘述,具体可参考终端侧生成RS序列的方法描述。It can be seen from the foregoing steps that the method for generating the RS sequence on the base station side is the same as that on the terminal side, and is not described here. For details, refer to the method for generating the RS sequence on the terminal side.
需要说明的是,基站侧在生成RS序列之后,根据RS序列生成参考信号,如参考信号序列经过映射等运算生成参考信号,并将生成的参考信号发送至终端。终端根据接收的RS序列以及本地生成的RS序列,可获得需要测量的信道信息。It should be noted that after generating the RS sequence, the base station side generates a reference signal according to the RS sequence, generates a reference signal by performing operations such as mapping on the reference signal sequence, and sends the generated reference signal to the terminal. The terminal can obtain channel information that needs to be measured according to the received RS sequence and the locally generated RS sequence.
因此,对于终端侧,还包括一种参考信号RS的接收方法,如图4所示,包括:Therefore, for the terminal side, a receiving method of the reference signal RS is also included, as shown in FIG. 4, including:
步骤401、终端从基站接收信令,所述信令用于指示一个或至少两个时间单元所使用的RS时域位置,所述时间单元的符号个数少于一个时隙slot的符号个数。Step 401: The terminal receives signaling from the base station, where the signaling is used to indicate an RS time domain location used by one or at least two time units, where the number of symbols of the time unit is less than the number of symbols of one slot. .
步骤402、终端根据所述信令,从基站接收RS。Step 402: The terminal receives the RS from the base station according to the signaling.
如此,终端可从基站接收信令,从而根据信令得知映射RS的具体符号位置,并 从得到的符号位置接收RS。从而实现正确从基站接收RS。In this way, the terminal can receive signaling from the base station, thereby knowing the specific symbol position of the mapped RS according to the signaling, and receiving the RS from the obtained symbol position. Thereby achieving correct reception of the RS from the base station.
其中,对于基站下发的信令,具体实施例时,可由多种实现方式,例如,信令可以包括符号K的信息,其中,所述符号K的信息为连续或不连续的N个时间单元所共享的RS时域位置所对应的符号的信息,在一种可能的设计中,连续或者不连续的N个时间单元可以共享RS序列。N可以在协议中预定义其数值,或者,基站发送到终端的信令中可以包含N的信息,如指示N的数值。For the signaling sent by the base station, in a specific embodiment, the implementation may be performed by multiple implementation manners. For example, the signaling may include information of the symbol K, where the information of the symbol K is continuous or discontinuous N time units. The information of the symbol corresponding to the shared RS time domain location, in one possible design, the RS sequence may be shared by consecutive or discontinuous N time units. N may pre-define its value in the protocol, or the signaling sent by the base station to the terminal may include information of N, such as a value indicating N.
举例来说,信令中包含一个K的取值,而终端侧通过协议预定义或者基站通过信令下发得知共享同一RS时域位置的多个时间单元的编号,例如为mini-slot#0、mini-slot#1、mini-slot#2、mini-slot#3,且K取值为10(作为示例),则终端从mini-slot#0、mini-slot#1、mini-slot#2、mini-slot#3中的第一个符号开始,往后第10个符号位置即为基站映射RS序列的符号位置,因而终端可从该位置接收基站侧的RS序列。For example, the signaling includes a value of K, and the terminal side pre-defines by the protocol or the base station sends out the number of the multiple time units sharing the same RS time domain location by using the signaling, for example, mini-slot# 0, mini-slot#1, mini-slot#2, mini-slot#3, and K is 10 (as an example), then the terminal is from mini-slot#0, mini-slot#1, mini-slot# 2. The first symbol in mini-slot#3 starts, and the 10th symbol position in the future is the symbol position of the base station mapping RS sequence, so the terminal can receive the RS sequence on the base station side from the location.
再比如,对于基站下发的信令,还可以是包括时间单元L的信息和在所述时间单元L上的符号P的信息;其中,所述时间单元L为共享同一RS时域位置的连续或不连续的N个时间单元中的第L个时间单元,所述符号P为所述第L个时间单元中的第P个符号,K为整数,N为正整数,L为不大于N的正整数,P为不大于时间单元所含的符号的个数。For example, the signaling sent by the base station may also be information including the time unit L and the information of the symbol P on the time unit L. The time unit L is a continuous time domain location sharing the same RS. Or the Lth time unit of the N consecutive time units, the symbol P is the Pth symbol in the Lth time unit, K is an integer, N is a positive integer, and L is not greater than N A positive integer, P is not more than the number of symbols contained in the time unit.
举例来说,信令中指示L的取值为2,P的取值为4,则表明共享同一RS时域位置的N个时间单元(如为mini-slot#0、mini-slot#1、mini-slot#2、mini-slot#3)中的第2个时间单元的第4个符号位置即为基站映射RS序列的符号位置,因此终端从该位置接收基站侧的RS序列。其中,同样地,N可以在协议中预定义其数值,或者,基站发送到终端的信令中可以包含N的信息,如指示N的数值。For example, the signaling indicates that the value of L is 2, and the value of P is 4, indicating that N time units sharing the same RS time domain location (eg, mini-slot#0, mini-slot#1) The fourth symbol position of the second time unit in mini-slot#2 and mini-slot#3) is the symbol position of the base station mapping RS sequence, so the terminal receives the RS sequence of the base station side from the position. In the same way, N may pre-define its value in the protocol, or the signaling sent by the base station to the terminal may include information of N, such as a value indicating N.
在一种可能的设计方法中,还可以是为每个mini-slot单独下发一个信令,用于指示该mini-slot所适用的RS时域位置信息。In a possible design method, a signaling may be separately sent for each mini-slot to indicate the RS time domain location information applicable to the mini-slot.
信令的形式可以为RRC,DCI或MAC CE。The signaling can be in the form of RRC, DCI or MAC CE.
在一种可能的设计中,终端接收到基站侧的RS序列之后,可根据接收的RS序列以及本地生成的RS序列,获得需要测量的信道信息。In a possible design, after receiving the RS sequence on the base station side, the terminal may obtain channel information that needs to be measured according to the received RS sequence and the locally generated RS sequence.
即在本申请实施例中,终端侧和基站侧以同样的方法生成RS序列,并且基站还将生成的RS序列映射到某个符号位置后发送给终端,终端通过找到该符号位置并接收基站侧的RS序列,并进一步地根据接收到的基站侧的RS序列以及本地生成的RS序列,获得需要测量的信道信息。That is, in the embodiment of the present application, the terminal side and the base station side generate an RS sequence in the same manner, and the base station also maps the generated RS sequence to a certain symbol position, and then sends the RS sequence to the terminal, and the terminal finds the symbol position and receives the base station side. The RS sequence, and further based on the received RS sequence of the base station side and the locally generated RS sequence, obtain channel information that needs to be measured.
作为一种替代的方案,本申请实施例,可由协议预定义独占或共享同一RS时域位置的多个时间单元接收RS的符号位置,从而终端可从协议预定义的符号位置处接收RS。As an alternative, in this embodiment of the present application, the symbol locations of the RSs may be received by a plurality of time units pre-defined by the protocol or sharing the same RS time domain location, so that the terminal may receive the RS from the symbol positions predefined by the protocol.
以上实施例,终端可根据第一参数集确定参考信号序列初始化值,并根据参考信号序列初始化值,生成RS序列,具体地,可应用于CSI-RS序列的生成、CRS序列的生成、DMRS序列的生成以及其他RS序列的生成,其中,第一参数集中包含的参数可参考目前现有的相应RS序列生成公式中所使用的参数,例如,针对CSI-RS序列的生成,所使用的第一参数集可参考LTE中在生成CSI-RS序列生成时所使用的公式中的参数集,但与LTE生成CSI-RS序列使用的参数集不同的是,本申请实施例中所使用的第一参数集中包含时间编号,且该时间单元所包含的符号个数是少于一个slot所 包含的符号个数,而目前LTE中生成CSI-RS序列时所使用的时间单元就是slot本身,由于在5G通信或未来5G以后的通信方式中,时间单元不再使用slot,而是使用比slot所包含的符号数更少的时间单元,因此为了适应一种通信制式下能够正确地生成RS序列,本申请实施例在生成RS序列时,是以该通信制式下的时间单元来生成RS序列,因此可保证在该通信制式下能够正确生成RS序列。In the foregoing embodiment, the terminal may determine the reference signal sequence initialization value according to the first parameter set, and generate an RS sequence according to the reference signal sequence initialization value, and specifically, may be applied to the CSI-RS sequence generation, the CRS sequence generation, and the DMRS sequence. And the generation of other RS sequences, wherein the parameters included in the first parameter set may refer to parameters used in the existing existing RS sequence generation formula, for example, for the generation of the CSI-RS sequence, the first used The parameter set may refer to the parameter set in the formula used in generating the CSI-RS sequence in the LTE, but different from the parameter set used by the LTE to generate the CSI-RS sequence, the first parameter used in the embodiment of the present application The set contains the time number, and the number of symbols included in the time unit is less than the number of symbols included in one slot, and the time unit used in generating the CSI-RS sequence in LTE is the slot itself, due to the 5G communication. Or in the future communication mode after 5G, the time unit no longer uses the slot, but uses less time units than the number of symbols included in the slot, so in order to adapt to one In the communication system, the RS sequence can be correctly generated. In the embodiment of the present application, when the RS sequence is generated, the RS sequence is generated by the time unit in the communication system, so that the RS sequence can be correctly generated under the communication system.
如图5所示,本申请实施例还提供一种参考信号RS生成方法,该方法执行主体为网络侧设备(如基站)、或为中继,或为终端,包括:As shown in FIG. 5, the embodiment of the present application further provides a reference signal RS generating method, where the method is performed by a network side device (such as a base station), or a relay, or a terminal, including:
步骤501、第一设备根据第二参数集,确定参考信号序列初始化值。Step 501: The first device determines, according to the second parameter set, a reference signal sequence initialization value.
步骤502、第一设备根据所述参考信号序列初始化值,生成RS序列。Step 502: The first device generates an RS sequence according to the reference signal sequence initialization value.
本申请实施例仍然是以现有协议中生成RS序列的公式基础上进行的改进,其中,第二参数集中对于时间单元相关的参数,可分为两种情形来说明。The embodiment of the present application is still based on the formula of the RS sequence generated in the existing protocol. The second parameter set is related to the time unit related parameters, which can be divided into two situations.
情形一、第二参数集包含第一参数 Case 1, the second parameter set includes the first parameter
所述第一参数为与时间单元的编号相关的参数,所述时间单元的编号与所述时间单元的类型相关。其中,一个时间单元包含的符号数为一个或多个,不同的时间单元的类型包含的符号数不同。The first parameter is a parameter related to the number of the time unit, and the number of the time unit is related to the type of the time unit. Wherein, one time unit contains one or more symbols, and different time unit types contain different numbers of symbols.
需要说明的是,图5所示的RS生成方法中关于时间单元的定义与图1和图3的RS生成方法中关于时间单元的定义是不相同的,在图1和图3中,时间单元包含的符号数少于slot包含的符号数,而图5所示的RS生成方法中,时间单元包含的符号数可能等于slot的符号数,也可能大于slot符号数,也可以是小于slot符号数,例如,在一种可能的设计中,slot包含7个符号或包含14个符号。It should be noted that the definition of the time unit in the RS generation method shown in FIG. 5 is different from the definition of the time unit in the RS generation method of FIGS. 1 and 3, and in FIG. 1 and FIG. 3, the time unit The number of symbols included is less than the number of symbols included in the slot. In the RS generation method shown in FIG. 5, the number of symbols included in the time unit may be equal to the number of symbols in the slot, or may be greater than the number of slots, or may be smaller than the number of slots. For example, in one possible design, the slot contains 7 symbols or contains 14 symbols.
因此,时间单元的类型是根据时间单元所包含的符号数确定的,例如时间单元包含7个符号或14个符号,则包含7个符号的时间单元为一个类型,包含14个符号的时间单元为一个类型。Therefore, the type of the time unit is determined according to the number of symbols included in the time unit. For example, if the time unit contains 7 symbols or 14 symbols, the time unit containing 7 symbols is one type, and the time unit containing 14 symbols is A type.
以上述CSI-RS生成公式为例,由于:Take the above CSI-RS generation formula as an example, because:
Figure PCTCN2018074199-appb-000041
Figure PCTCN2018074199-appb-000041
因此,n’ s即为本申请实施例的第二参数集中的第一参数,该参数是根据时间单元的编号确定的,并且时间单元的编号又是根据时间单元的类型确定的。 Thus, n 's of the present application is the first parameter of the second embodiment of the parameter set, the parameter is determined according to the number of time units, and the number of time units is determined according to the type of time unit.
情形二、第二参数集包含第二参数和第三参数 Case 2, the second parameter set includes the second parameter and the third parameter
所述第二参数为与时间单元的类型相关的参数,所述第三参数为与时间单元的编号相关的参数。The second parameter is a parameter related to the type of the time unit, and the third parameter is a parameter related to the number of the time unit.
其中,第三参数与情形一中的第一参数类似,为与时间单元的编号相关的参数,即上述公式中的n’ s(当然,上述公式只是举例,并不限于上述公式)。 The third parameter is similar to the first parameter in the first case, and is a parameter related to the number of the time unit, that is, n' s in the above formula (of course, the above formula is only an example, and is not limited to the above formula).
为方便说明,第二参数可用N slot表示,例如,以时间单元的类型包含7个符号和包含14个符号为例,在一种可能的实现方式中, For convenience of description, the second parameter may be represented by N slot . For example, the case where the type of the time unit includes 7 symbols and includes 14 symbols is taken as an example. In a possible implementation manner,

本申请实施例,第一设备可根据第二参数集确定参考信号序列初始化值,并根据参考信号序列初始化值,生成RS序列,其中第二参数集中包含第一参数,或者包含 第二参数和第三参数,其中,第一参数为时间单元的编号相关的参数,第二参数为与时间单元的类型相关的参数,第三参数为与时间单元的编号相关的参数,从而可基于时间单元的编号或者基于时间单元的类型和时间单元的编号得到RS序列。In this embodiment, the first device may determine the reference signal sequence initialization value according to the second parameter set, and generate an RS sequence according to the reference signal sequence initialization value, where the second parameter set includes the first parameter, or includes the second parameter and the a three parameter, wherein the first parameter is a parameter related to the number of the time unit, the second parameter is a parameter related to the type of the time unit, and the third parameter is a parameter related to the number of the time unit, thereby being based on the number of the time unit Or the RS sequence is obtained based on the type of the time unit and the number of the time unit.
本申请实施例中,在不同的时间单元的编号方式下,对应的RS序列的生成方式不同,因此,下面首先对本申请实施例对于时间单元的编号方式进行说明。In the embodiment of the present application, the manner of generating the corresponding RS sequence is different in the numbering manner of different time units. Therefore, the numbering manner of the time unit in the embodiment of the present application is first described below.
为方便说明,图5所示的RS生成方法中,时间单元以slot为例,并且以一个slot包含的符号数为7个或14个为例进行说明。以及,将包含7个符号的slot称为参考slot(或称为参考时间单元),当然,也可以是将包含其他符号数量的时间单元作为参考slot,本申请实施例对此不做限定。可以理解的是,本发明实施例也可以应用于除slot之外的时间单元,如一个时间单元所包括的符号个数少于slot的时间单元,如mini-slot中,在此不予赘述。For convenience of description, in the RS generation method shown in FIG. 5, the time unit is exemplified by a slot, and the number of symbols included in one slot is 7 or 14 as an example. In addition, the slot containing the 7 symbols is referred to as a reference slot (or a reference slot unit). Of course, the time unit including the number of other symbols may be used as a reference slot, which is not limited in this embodiment of the present application. It can be understood that the embodiment of the present invention can also be applied to a time unit other than a slot. For example, a time unit includes a time unit with fewer symbols than a slot, such as a mini-slot, and details are not described herein.
并且,所述参考时间单元的类型为网络侧配置或预定义的时间单元类型。And, the type of the reference time unit is a network side configuration or a predefined time unit type.
本申请实施例,第一设备根据时间单元的类型,确定时间单元的编号In this embodiment of the present application, the first device determines the number of the time unit according to the type of the time unit.
slot编号方式一Slot numbering method one
参考图6,为本申请实施例提供的第一种slot编号方式,根据slot的类型对应的符号数量,确定无线帧中slot的编号,或者是根据slot的类型对应的符号数量,及slot所在的子帧的序号,确定无线帧中slot的编号。Referring to FIG. 6, the first slot numbering method provided by the embodiment of the present application determines the number of the slot in the radio frame according to the number of symbols corresponding to the type of the slot, or the number of symbols corresponding to the type of the slot, and the slot number. The sequence number of the subframe determines the number of the slot in the radio frame.
即,对于包含7个符号的slot和包含14个符号的slot分别进行按序编号,具体地,对于包含7个符号的slot,则依次编号为0,1,2,3,4,5,……,同样地,对于包含14个符号的slot,也是依次编号为0,1,2,3,4,5,……。That is, the slot containing 7 symbols and the slot containing 14 symbols are numbered sequentially, specifically, for a slot containing 7 symbols, it is sequentially numbered 0, 1, 2, 3, 4, 5,... ..., likewise, for a slot containing 14 symbols, it is also numbered 0, 1, 2, 3, 4, 5, ....
举例来说,一个无线帧有10个子帧,每个子帧包含2个slot,且每个slot包含的符号相同(例如均为7个符号或14个符号),则第5个子帧上的第2个slot的编号可以是通过从前往后依次编号,得到其编号为9(从0开始算),或者是根据该slot为第5个子帧的第2个slot,因此其编号=子帧编号*子帧中slot数+子帧中的slot编号=4*2+1=9。可以理解的是,这里的子帧,无线帧均可以为其他名称,子帧,无线帧及slot之间的关系也可以为其他的关系,在此不予赘述。For example, a radio frame has 10 subframes, each subframe contains 2 slots, and each slot contains the same symbol (for example, 7 symbols or 14 symbols), and the 2nd subframe is the 2nd subframe. The number of the slot can be obtained by numbering from the beginning to the end, and the number is 9 (calculated from 0), or the second slot according to the slot is the 5th subframe, so its number = subframe number * sub The number of slots in the frame + the slot number in the subframe = 4 * 2 + 1 = 9. It can be understood that the subframes and the radio frames herein may be other names, and the relationship between the subframes, the radio frames, and the slots may also be other relationships, and details are not described herein.
slot编号方式二Slot numbering method two
参考图7,为本申请实施例提供的第二种slot编号方式,该编号方式是根据slot的类型对应的符号数量及参考slot的类型对应的符号数量,确定slot的编号;或者,根据slot的类型对应的符号数量及参考时间单元的类型对应的符号数量,及slot所在的子帧的序号,确定slot的编号;其中,参考slot的类型为基站侧配置或预定义。Referring to FIG. 7, a second slot numbering manner is provided according to an embodiment of the present application. The numbering manner is to determine the slot number according to the number of symbols corresponding to the type of the slot and the number of symbols corresponding to the type of the reference slot; or, according to the slot. The number of symbols corresponding to the type and the number of symbols corresponding to the type of the reference time unit, and the sequence number of the subframe in which the slot is located, determine the number of the slot; wherein the type of the reference slot is configured or predefined on the base station side.
或者也可以理解为:根据时间单元所对应的参考时间单元的编号,确定时间单元的编号。Or it can be understood as: determining the number of the time unit according to the number of the reference time unit corresponding to the time unit.
即,将时间单元与参考时间单元进行混合编号,例如,对于包含7个符号的时间单元,则按序编号,对于包含14个符号的时间单元,由于包含两个子单元,分别对应一个参考时间单元,因此其可对应两个编号,具体编号时可选择其中一个作为时间单元的编号,例如选择时间单元所对应的参考时间单元的第Q(这个例子中,Q=1或Q=2)个编号,作为时间单元的编号,如选择第1个编号作为时间单元的编号,当然也可以选择其他编号作为时间单元的编号,参考图7,对于包含7个符号的slot,分别编号为0,1,而对于包含14个符号的slot,由于参考slot的符号个数为7个,因此,该包含14个符号的slot包含两个子单元,因此可对应两个编号,例如分别为2和3,则对于该时间单元(slot),其编号可以为2,也可以为3,具体根据实际情况而定。That is, the time unit is mixed with the reference time unit, for example, for a time unit containing 7 symbols, it is numbered sequentially, and for a time unit including 14 symbols, since two sub-units are included, one reference time unit is respectively corresponding. Therefore, it can correspond to two numbers. When the number is specific, one of them can be selected as the number of the time unit. For example, the Q of the reference time unit corresponding to the time unit (Q=1 or Q=2 in this example) is selected. As the number of the time unit, if the first number is selected as the number of the time unit, of course, other numbers may be selected as the number of the time unit. Referring to FIG. 7, for the slot containing 7 symbols, the numbers are 0, 1, respectively. For a slot containing 14 symbols, since the number of symbols of the reference slot is 7, the slot containing 14 symbols includes two subunits, and thus can correspond to two numbers, for example, 2 and 3, respectively. The time slot (slot) may be numbered 2 or 3, depending on the actual situation.
slot编号方式三Slot numbering mode three
参考图8,为本申请实施例提供的第三种slot编号方式,该编号方式是根据slot的类型对应的符号数量及编号间隔,确定无线帧中slot的编号;或者,根据slot的类型对应的符号数量、slot所在的子帧的序号及编号间隔,确定无线帧中slot的编号;其中,编号间隔为第一设备根据slot的类型对应的符号数与参考slot的类型对应的符号数确定,所述参考时间单元的类型为基站侧配置或预定义。Referring to FIG. 8 , a third slot numbering manner is provided in the embodiment of the present disclosure. The numbering manner is to determine the number of the slot in the radio frame according to the number of symbols and the number interval corresponding to the type of the slot; or, according to the type of the slot. The number of the symbol, the sequence number of the subframe in which the slot is located, and the number interval, and the number of the slot in the radio frame is determined. The number interval is determined by the first device according to the number of symbols corresponding to the type of the slot and the number of symbols corresponding to the type of the reference slot. The type of reference time unit is configured or predefined on the base station side.
例如,针对图8所示的情形,则编号间隔的计算公式为:
Figure PCTCN2018074199-appb-000043
其中,N symbol为slot包含的符号数,
Figure PCTCN2018074199-appb-000044
为参考slot包含的符号数。如,当前slot包含14个符号,参考slot包含7个符号,则编号间隔为14/7=2。因此参照图8,对于包含14个符号的slot,其编号方式如图8所示,依次编号为0,2,……,而对于包含7个符号的slot,由于其对应的编号间隔为7/7=1,因此实际上是按自然数依次编号。
For example, for the situation shown in Figure 8, the calculation of the numbering interval is:
Figure PCTCN2018074199-appb-000043
Where N symbol is the number of symbols contained in the slot.
Figure PCTCN2018074199-appb-000044
For the reference to the number of symbols contained in the slot. For example, if the current slot contains 14 symbols and the reference slot contains 7 symbols, the number interval is 14/7=2. Therefore, referring to FIG. 8, for a slot containing 14 symbols, the numbering manner is as shown in FIG. 8, which is sequentially numbered 0, 2, ..., and for a slot containing 7 symbols, since the corresponding numbering interval is 7/ 7=1, so it is actually numbered sequentially by natural number.
slot编号方式四Slot numbering method four
参考图9,为本申请实施例提供的第四种slot编号方式,该编号方式下,一个slot可以对应一个或多个时间单元,每个子单元对应一个参考时间单元,每个子单元具有所对应的参考时间单元的编号,具体地,根据slot的类型对应的符号数量,确定slot的编号;或者,Referring to FIG. 9, a fourth slot numbering manner is provided in the embodiment of the present application. In the numbering mode, one slot may correspond to one or more time units, and each subunit corresponds to one reference time unit, and each subunit has a corresponding one. Referring to the number of the time unit, specifically, determining the number of the slot according to the number of symbols corresponding to the type of the slot; or,
根据slot的类型对应的符号数量,及slot所在的子帧的序号,确定slot的编号。The number of the slot is determined according to the number of symbols corresponding to the type of the slot and the sequence number of the subframe in which the slot is located.
参考图9,其中,参考slot为包含7个符号的slot,因此对于包含14个符号的slot,由于对应两个参考slot,因此,包含两个时间单元(图9所示的2和3),即每个子单元(与参考slot包含的符号数相同)对应一个编号。Referring to FIG. 9, wherein the reference slot is a slot containing 7 symbols, so for a slot containing 14 symbols, since two reference slots are corresponding, two time units are included (2 and 3 shown in FIG. 9), That is, each subunit (same number of symbols as the reference slot contains) corresponds to a number.
在对slot按照上述任一种编号方式进行编号之后,则可进一步根据编号之后的slot确定参考信号序列初始化值。After the slots are numbered according to any of the above numbering methods, the reference signal sequence initialization value may be further determined according to the slot after the numbering.
下面分两种情形进行说明。The following two cases are explained.
情形一、第二参数集中包含第一参数 Case 1, the second parameter set contains the first parameter
其中,第一参数为与时间单元的编号相关的参数,以CSI-RS的生成公式为例,则第一参数为其中的n’ s,即根据时间单元的编号,确定出n’ s,进而根据确定出的n’ s,及第二参数集中的其它参数,确定出参考信号序列初始化值。 Wherein the first parameter is a parameter related to the number of time units to generate the CSI-RS Equation an example, the first parameter in which the n 's, i.e. according to the numbering unit time, is determined n' s, and further The reference signal sequence initialization value is determined according to the determined n 's and other parameters in the second parameter set.
该情形一的计算方式适用于上述slot编号二和slot编号方式四,具体地,可仍然沿用现有协议中的参考信号序列初始化值的生成公式,即:The calculation method of the first case is applicable to the slot number 2 and the slot numbering manner 4 described above. Specifically, the formula for generating the initialization value of the reference signal sequence in the existing protocol may still be used, that is,
Figure PCTCN2018074199-appb-000045
Figure PCTCN2018074199-appb-000045
其中,n’ s为第一参数,且该第一参数是根据时间单元的编号确定,时间单元的编号时根据上述编号方式二和编号方式四确定。 Where n' s is the first parameter, and the first parameter is determined according to the number of the time unit, and the number of the time unit is determined according to the above numbering mode 2 and numbering mode 4.
需要说明的是,上述只是以CSI-RS的生成公式为例进行说明,但不限于CSI-RS的生成公式,也可适用于其他RS序列生成公式。It should be noted that the above description is based on the CSI-RS generation formula. However, the present invention is not limited to the CSI-RS generation formula, and may be applied to other RS sequence generation formulas.
情形二、第二参数集包含第二参数和第三参数 Case 2, the second parameter set includes the second parameter and the third parameter
可选地,所述第三参数为所述时间单元的编号,所述时间单元的编号为以自然数依次编号,或,所述第三参数根据所述时间单元的编号,时间单元的类型对应的符号数量及参考时间单元的类型对应的符号数量确定,所述时间单元的编号根据所述时间单元的类型对应的符号数量及编号间隔确定,所述编号间隔为根据所述时间单元的类型及所述参考时间单元的类型确定,所述参考时间单元的类型为基站侧配置或预定义。Optionally, the third parameter is a number of the time unit, the number of the time unit is sequentially numbered by a natural number, or the third parameter is corresponding to the type of the time unit according to the number of the time unit. The number of symbols and the number of symbols corresponding to the type of the reference time unit are determined, and the number of the time unit is determined according to the number of symbols and the number interval corresponding to the type of the time unit, and the number interval is according to the type and location of the time unit. The type of the reference time unit is determined, and the type of the reference time unit is configured or predefined on the base station side.
所述第二参数根据所述时间单元的类型确定。The second parameter is determined according to the type of the time unit.
其中,当第三参数为时间单元的编号时,其对应上述编号方式一,并且相应地, 可将CSI-RS的生成公式中的c init的生成方式修改为: Wherein, when the third parameter is the number of the time unit, it corresponds to the above numbering mode one, and correspondingly, the generating manner of c init in the CSI-RS generating formula can be modified to:

在一种可能的设计中,本申请实施例还提供一种参考信号序列初始化值的计算方式,以CSI-RS为例,CSI-RS在现有协议中的计算公式中:In a possible design, the embodiment of the present application further provides a method for calculating a reference signal sequence initialization value, and taking CSI-RS as an example, the calculation formula of the CSI-RS in the existing protocol:
