Abstract

Provided in embodiments of the present application are a method and apparatus for processing a reference signal. The method comprises: determining a base sequence on the basis of a first Zadoff-Chu sequence that has a length of N_zc; according to the base sequence, generating a reference signal sequence that has a length of M; and then generating a reference signal according to the reference signal sequence and sending same to a receiving end. The base sequence is one of L candidate base sequences, wherein L≥31 and L is an integer; and the value of N_zc is a prime number in the set [97,431]. In the embodiments of the present application, since the Zadoff-Chu sequence used for generating the candidate base sequence is longer, the number of candidate base sequences increases, so that the number of base sequences available in one cell may be increased, thus satisfying the demand for a large number of terminals in the one cell to require more base sequences in a scenario in which the number of terminals in the cell has greatly increased, and the terminals in the cell do not need to make different terminals take turns sending uplink reference signals by means of a time division manner, which ensures the performance of a system.

Description

Reference signal processing method and device

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office, the application number is 201910708283.8, and the application name is "reference signal processing method and device" on August 1, 2019, the entire content of which is incorporated into this application by reference .

Technical field

This application relates to the field of communication technology, and in particular to a method and device for processing a reference signal.

Background technique

Long-term evolution (LTE) and new radio (NR) technology uplink reference signals (such as uplink demodulation reference signal (DMRS)), uplink sounding reference signal (sounding reference signal, SRS)) or the sequence of the downlink reference signal is generated from a base sequence (base sequence) of length M. For example, the base sequence of length M is r(m), m=0,1,2,...,M-1, then the reference signal sequence generated by the base sequence can be:

A·exp(jαm)·r(m),m=0,1,2,...,M-1,

Among them, M is an integer greater than 1, α is a value determined by the time-domain cyclic shift value, which is a real number, j is the unit of an imaginary number, and A is a complex number.

The aforementioned base sequence can be generated by a Zadoff-Chu sequence of length N, for example, the Zadoff-Chu sequence itself, or a sequence generated by the Zadoff-Chu sequence through cyclic expansion or interception. For example, the Zadoff-Chu sequence of length N is z _q (n), n=0,1,...,N-1, the sequence of length M generated by the Zadoff-Chu sequence can be expressed as: z _q ( m mod N), m=0,1,...,M-1. Among them, the Zadoff-Chu sequence of length N can be expressed as follows:

Among them, N is the length of the Zadoff-Chu sequence, which is an integer greater than 1; q is the root of the Zadoff-Chu sequence, which is a natural number that is relatively prime to N, and 0<q<N.

Taking SRS as an example, the terminal device needs to determine the SRS sequence according to the base sequence before sending the SRS. In the 3rd generation partnership project (the 3rd generation partnership project, 3GPP) standard, a variety of M SRS sequences are defined. Among them, when M is an integer greater than or equal to 36 and less than 72, 30 base sequences are defined respectively, where the 30 base sequences are generated from Zadoff-Chu sequences with the same length and different roots. Furthermore, these 30 base sequences are divided into 30 groups. The base sequences of different groups can be assigned to different cells. Taking M=36 as an example, the 30 base sequences are generated by Zadoff-Chu sequences of length 31. These Zadoff- The relationship between the root of the Chu sequence and the group number of the base sequence can be referred to Table 1:

Table 1

At this time, each cell is assigned a base sequence to generate the final transmitted SRS sequence, that is, in a cell, each terminal device that transmits the same length of the SRS sequence at the same time uses the same base sequence to generate the SRS sequence . When using the same base sequence to generate the SRS sequence, the terminal equipment in a cell obtains the orthogonality between the SRS sequences by using different time domain cyclic shifts and/or time-frequency domain resources.

For each value of M greater than or equal to 72, 60 base sequences are respectively defined, where the 60 base sequences are generated from Zadoff-Chu sequences with the same length and different roots. Further, the 60 base sequences are divided into 30 groups, and the base sequences of different groups can be allocated to different cells. Taking M=72 as an example, the Zadoff-Chu sequence of length 71 is generated for 30 groups of base sequences. The relationship between the roots of these Zadoff-Chu sequences and the group numbers of the base sequences can be referred to Table 2:

Table 2

At this time, each cell is allocated a sequence group to generate the final transmitted SRS sequence, and each sequence group includes 2 base sequences of the same length. However, in a cell, each terminal device that transmits an SRS sequence of the same length on the same time-frequency resource uses the SRS sequence generated by the same base sequence in the sequence group corresponding to the cell. That is, in the actual system, the two base sequences of the same base sequence group are used as hopping sequences, that is, at different moments, the base sequence used by a terminal device can be between the two base sequences in this group. The purpose of hopping according to the designed pattern is to randomize the interference between cells.

Therefore, in the current system, on the same time-frequency resource, only one base sequence is available for the SRS sequence of a cell. However, the number of terminal devices in each cell is large (for example, 200), and the number of time-domain cyclic shifts that can obtain better orthogonality and the number of available time-frequency domain resources are very limited in an actual system. Therefore, the current number of available SRS sequences in a cell is far from sufficient for the huge number of terminal devices. This leads to the need to allow different terminal devices to send SRS in turn in a time division manner, resulting in a larger SRS cycle, such as 20 ms. However, the channel has time-varying characteristics, and the large SRS period causes the channel state information obtained through SRS to be easily outdated. The channel state information during downlink data transmission is very different from the channel state information measured by the previous SRS, which seriously affects the system Performance.

Detailed ways

Before describing the technical solutions of this application, the terms involved in this application are introduced as follows:

1. [A, B] represents a collection of integers greater than or equal to A and less than or equal to B.

2. Base sequence and corresponding reference signal sequence:

If the base sequence of length M is r(m), m=0,1,2,...,M-1, the reference signal sequence generated by the base sequence can be:

A·exp(jαm)·r(m),m=0,1,2,…,M-1

The aforementioned base sequence r(m) can be generated by a Zadoff-Chu sequence of length N, such as the Zadoff-Chu sequence itself, or a sequence generated by the Zadoff-Chu sequence through cyclic expansion or interception. For example, the Zadoff-Chu sequence of length N is z _q (n), n=0,1,...,N-1, the sequence of length M generated by the Zadoff-Chu sequence can be expressed as: z _q ( m mod N), m=0,1,...,M-1. Among them, the Zadoff-Chu sequence of length N can be expressed as follows:

In other words, a Zadoff-Chu sequence of length N can have N-1 roots, corresponding to N-1 base sequences of length M. According to the base sequence generated by a root of a Zadoff-Chu sequence of length N, different reference signal sequences can be obtained by using different cyclic shift values α.

3. The embodiment of the application defines a sequence group as a set of all base sequences with the same group index (or cell index).

In a general scheme, the base sequence of the reference signal sequence used to generate the device is determined based on the Zadoff-Chu sequence of length N ₁ , where N ₁ is the largest prime number less than or equal to M, or the smallest number greater than or equal to M. Prime number, that is, N _{1 is} less than or equal to M or slightly greater than M. Then when M is small, for example, M=36, 48, and N ₁ is also small.

And the total number of roots of the Zadoff-Chu sequence with length N ₁ is equal to N ₁ -1, and the Zadoff-Chu sequence with length N ₁ corresponds to N ₁ -1 base sequences, then M is smaller, N ₁ is also smaller In the case of, the number of available base sequences determined based on the Zadoff-Chu sequence of length N ₁ is small, which cannot meet the needs of the large number of terminals in the current system. It is necessary to let different terminals send references in turn in a time division manner. Signal, resulting in a larger reference signal period. However, the channel has time-varying characteristics, and the large reference signal period causes the channel state information obtained through the reference signal to be easily outdated, that is, the channel state information during data transmission is very different from the channel state information measured by the reference signal before, which is serious.

V2X communication is aimed at high-speed devices represented by vehicles. It is the basic technology and key technology applied in scenarios with very high communication delay requirements in the future, such as smart cars, autonomous driving, and intelligent transportation systems.

As shown in Figure 2, vehicles or vehicle components communicate via V2V. Vehicles or vehicle components can broadcast their own speed, driving direction, specific location, whether emergency brakes are stepped on, and other information to surrounding vehicles. Drivers of surrounding vehicles can better perceive traffic conditions outside the line of sight by obtaining such information , So as to make advance judgments of dangerous situations and make avoidance; vehicles or vehicle components communicate with roadside infrastructure through V2I, and roadside infrastructure can provide various types of service information and data network access for vehicles or vehicle components . Among them, non-stop charging, in-car entertainment and other functions have greatly improved traffic intelligence. Roadside infrastructure, for example, roadside unit (RSU) includes two types: one is a terminal equipment type RSU.

Among them, the network architecture and business scenarios described in the embodiments of this application are intended to more clearly illustrate the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. Those of ordinary skill in the art will know that With the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems.

The following describes the reference signal processing method of the embodiment of the present application.

FIG. 3 is the first interaction of a reference signal processing method provided by an embodiment of this application. Referring to Fig. 3, the method of this embodiment includes:

Step S201: The first node generates a reference signal according to a reference signal sequence of length M; where the reference signal sequence is generated from a first base sequence, and the first base sequence is generated from a Zadoff-Chu sequence of length N _zc , Wherein N _zc > M and N _zc is an integer; the first base sequence is one of L candidate base sequences; L≥31 and L is an integer.

In this embodiment, the L candidate base sequences include L ₁ base sequences generated from Zadoff-Chu sequences with a length of N _zc , L ₁ ≥1, and L ₁ ≤L.

When L ₁ =L, the L candidate base sequences include L base sequences generated from Zadoff-Chu sequences with a length of N _zc . When L ₁ <L, the L candidate base sequences include not only L ₁ base sequences generated from Zadoff-Chu sequences of length N _zc , but also LL ₁ base sequences generated from Zadoff-Chu sequences of other lengths. LL ₁ base sequence generated from Zadoff-Chu sequences of other lengths can be generated from Zadoff-Chu sequences of the same or different lengths, which is not limited in the embodiment of the present application. The other lengths here are not equal to N _zc and not equal to N ₁ .

Among them, the base sequence generated by the Zadoff-Chu sequence of length N _x , the base sequence is generated by the Zadoff-Chu sequence of length N _x , the specific meaning of the two is: the base sequence is the length of N _x The Zadoff-Chu sequence itself, or the base sequence is obtained by cyclic shift expansion or truncation from a Zadoff-Chu sequence of length N _x . It is understandable that the base sequence can also be calculated based on the roots of the Zadoff-Chu sequence with length N _x , M and length N _x . That is, the base sequence is determined based on the Zadoff-Chu sequence of length N _x . It is understandable that "the first base sequence is generated from a Zadoff-Chu sequence of length N _zc " is not limited to the following steps when the first node generates a reference signal from a reference signal sequence of length M: based on the length N _zc Zadoff-Chu sequence of sequence determination of the first group, or a length N _zc according to the Zadoff-Chu sequence, generating a first sequence group. In other words, according to the Zadoff-Chu sequence of length N _zc , generating the first base sequence is an optional step.

The reference signal sequence is generated from the first base sequence. It can be understood that the reference signal sequence may be calculated from the first base sequence and the cyclic shift value α through a predefined rule; or, the reference signal sequence may be based on Obtained from the first base sequence and the first correspondence, the first correspondence is the correspondence between the L candidate base sequences, the cyclic shift value α, and the reference signal sequence. It is understandable that the base sequence used by different nodes to generate the reference signal sequence may be different, but the base sequence used by each node belongs to L candidate base sequences. It is understandable that “the reference signal sequence is generated by the first base sequence” is not limited to the following steps in the process of generating the reference signal by the first node according to the reference signal sequence of length M: according to the first base sequence, Reference signal sequence.

In a cellular mobile network communication system, if the reference signal is an uplink reference signal, the first node is a terminal, and if the reference signal is a downlink reference signal, the first node is a network device. In the V2X communication system, the reference signal may be a side link reference signal. The reference signal in this embodiment includes but is not limited to SRS and DMRS.

In another implementation manner, before the first node generates the reference signal, the first node obtains a reference signal sequence of length M. It should be understood that the first node acquiring the reference signal sequence of length M may be a reference signal sequence that the first node obtains by looking up a table in advance, or the first node may generate a reference signal according to the first base sequence and a predefined rule The sequence is not limited in the embodiment of this application. Among them, the predefined rule here can be the following formula, but is not limited to the following formula:

S(m)=A·exp(jαm)·r(m), m=0,1,2,...,M-1

Among them, S(m) is the reference signal sequence, r(m) is the first base sequence, and α is the cyclic shift value used to generate the reference signal sequence.

In the first solution, the first node obtains the pre-generated reference signal sequence by looking up the table. The first node may store multiple reference signal sequences of length M and respective indexes of multiple reference signal sequences of length M, and the first node obtains the reference signal sequence of length M according to the index of the reference signal sequence.

In the second solution, the first node generates a reference signal sequence of length M, specifically: the first node generates a reference signal sequence of length M according to the first base sequence of length M. Among them, the first base sequence is generated from a Zadoff-Chu sequence with a length of N _zc .

The acquisition of the first base sequence involved in the process of generating the reference signal by the first node according to the reference signal sequence of length M in the second solution will be described below.

The first node obtains the first base sequence according to the configuration information. In the wireless communication network shown in FIG. 1 (ie, the cellular mobile network communication system), if the first node is a terminal, the configuration information may be sent by the network device to the first node. At this time, the network device is the second node; if The first node is a network device, and the configuration information is determined by the network device. In the V2X communication system shown in Figure 2, when the first node and the second node are both within the coverage of the cellular mobile network, the configuration information can be sent by the network device to the first node, or sent by the network device to After the second node, the second node sends to the first node. When the first node is not within the coverage of the cellular mobile network, the configuration information may be sent by the second node to the first node. It can be understood that the L candidate base sequences are L base sequences corresponding to all possible values of the configuration information.

Among them, the configuration information includes but is not limited to the following implementation modes:

The first implementation manner: the configuration information includes first indication information, and the first indication information indicates the first base sequence for generating the reference signal sequence.

It should be noted that the first indication information may be displayed and configured, or may be implicitly obtained through the configuration of other information, which is not limited in the embodiment of the present application.

Exemplarily, the first indication information indicates the index of the first base sequence. At this time, all possible values of the configuration information indicate the indexes of the L candidate base sequences. Correspondingly, in the case where the first indication information indicates the index of the first base sequence, the first node obtains the first base sequence according to the configuration information, including: the first node obtains the first base sequence according to the index of the first base sequence and the length of the reference sequence M , Get the first base sequence.

Exemplarily, the first indication information indicates the sequence index of the first Zadoff-Chu sequence for generating the first base sequence. At this time, all possible values of the configuration information include the indexes corresponding to the L Zadoff-Chu sequences. Correspondingly, the first node obtains the first base sequence according to the configuration information, including: the first node obtains the first Zadoff-Chu sequence for generating the first base sequence according to the first indication information, and the first node obtains the first Zadoff-Chu sequence according to the first Zadoff -The length M of the Chu sequence and the reference signal sequence to generate the first base sequence. Wherein, in this implementation, the first base sequence is generated according to the length M of the first Zadoff-Chu sequence and the reference signal sequence. It can be understood that the first base sequence may be calculated by the first Zadoff-Chu sequence according to a predefined rule Alternatively, the first base sequence may be obtained according to the first Zadoff-Chu sequence and the second correspondence, and the second correspondence is the correspondence between the L candidate base sequences and the L Zadoff-Chu sequences. The predefined rule here can be that when M is greater than the length N _zc of the first Zadoff-Chu sequence, the first Zadoff-Chu sequence is expanded by cyclic shift to obtain the first base sequence, and when M is less than N _zc , the first base sequence is obtained by intercepting The first Zadoff-Chu sequence obtains the first base sequence. When M is equal to N _zc , the first Zadoff-Chu sequence is determined to be the first base sequence.

Exemplarily, the first indication information indicates the length N _{zc of the} first Zadoff-Chu sequence and the corresponding root q. In this case, all possible values of the configuration information include the length and root corresponding to the L Zadoff-Chu sequences that generate L candidate base sequences; or, all the possible values of the configuration information include the generation of L candidate base sequences The indication information of the roots of the L Zadoff-Chu sequences and the length of the L Zadoff-Chu sequences to generate the L candidate base sequences. Correspondingly, the first node obtains the first base sequence according to the configuration information, including: the first node obtains the length N _zc and root q of the first Zadoff-Chu sequence according to the first indication information, and the first node obtains the length N _zc and root q of the first Zadoff-Chu sequence according to the N _zc and q and M generate a first base sequence; or, the first node obtains the length N _zc and root q of the first Zadoff-Chu sequence according to the first indication information, and the first node _obtains the length N _zc and root q of the first Zadoff-Chu sequence according to N _zc , q, M and the third correspondence relationship The first base sequence is generated, and the third correspondence is the length of L Zadoff-Chu sequences and the correspondence between roots and L Zadoff-Chu sequences.

Exemplarily, the first indication information indicates the root q of the first Zadoff-Chu sequence. In this case, all possible values of the configuration information may include the roots of L Zadoff-Chu sequences for generating L candidate base sequences; or, all possible values of the configuration information may include L for generating L candidate base sequences. Indication information of the root of a Zadoff-Chu sequence. Correspondingly, the first node obtains the first base sequence according to the configuration information, including: the first node obtains the root q of the first Zadoff-Chu sequence according to the first indication information, and the first node obtains the root q of the first Zadoff-Chu sequence according to the length of the first Zadoff-Chu sequence N _zc , q and M obtain the first basis sequence; or, the first node obtains the root q of the first Zadoff-Chu sequence according to the first indication information, and the first node obtains the first basis sequence according to q, M and the fourth correspondence Sequence, the fourth correspondence is the correspondence between L roots and L Zadoff-Chu sequences. At this time, the length N _zc of the first Zadoff-Chu sequence is pre-configured.

Second implementation mode: the configuration information includes second indication information and third indication information. The second indication information is used to indicate the sequence group where the first base sequence is located. (For the convenience of description, the first base sequence is located in this embodiment. The sequence group is called the target sequence group), and the third indication information is used to indicate the first base sequence in the target sequence group.

It should be noted that the second instruction information and the third instruction information may be sent through the same instruction or through different instructions, which is not limited in the embodiment of the present application. In addition, the second indication information and the third indication information may be displayed configuration, for example, the second indication information indicates the group index of the target sequence group, and the third indication information indicates the base sequence index in the target sequence group; or, the second indication The information and the third indication information may also be obtained implicitly through the configuration of other information, which is not limited in the embodiment of the present application.

Exemplarily, the second indication information indicates the group index or the cell index of the target sequence group, and the third indication information indicates the index of the first base sequence in the target sequence group. In this case, all possible values of the configuration information include the group index of each group and the index of the base sequence in each group in the respective sequence group. Correspondingly, the first node obtains the first base sequence according to the configuration information, including: the first node obtains the group index or cell index of the target sequence group according to the second indication information, and obtains the first base sequence in the target sequence according to the third indication information The group index is based on the group index or cell index of the target sequence group and the index of the first base sequence in the target sequence group to obtain the first base sequence.

The length M of the reference signal sequence (the length M of the first base sequence) and the lengths N _zc and L of the Zadoff-Chu sequence corresponding to the first base sequence will be described below.

For the length of the reference signal series M: M can be any positive integer, for example: 6, 12, 24, 30, 36, 40, 48, 50, 60, 66, 72, 80, 84, 96, 100, 120, 2200 and so on. Optionally, 36≤M≤96 and M is an integer.

For the number of candidate base sequences L: L is an integer greater than or equal to 31. Wherein, the value range of L includes but is not limited to one of the following: 31≤L<90, 90≤L<120, 90≤L<120, L≥120.

For the length of the first Zadoff-Chu sequence N _zc , N _zc >M. N _zc can be a prime number in the set [97,431]. That is, the value of N _zc can be one of the following: 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191 , 193,197,199,211,223,227,229,233,239,241,251,257,263,269,271,277,281,283,293,307,311,313,317,331,337 , 347,349,353,359,367,373,379,383,389,397,401,409,419,421,431. When N _zc is a prime number in the set [97,431], the cross-correlation between the reference signals generated by the L candidate base sequences is small. In addition, when N _zc is a prime number in the set [97,431], the PAPR of the reference signal generated by the L candidate base sequences is low (for example, less than 5dB), where the reference signal generated by the L candidate base sequences The PAPR is low, which can effectively improve the coverage of the reference signal. In addition, in order to avoid that different cells use the same base sequence to generate reference signals and cause strong inter-cell interference, in practical applications, the L candidate base sequences may be divided into multiple sequence groups that do not contain the same base sequence. In this case, when When N _zc is a prime number in the set [97,431], the interference between the reference signals generated by the candidate base sequences included in each sequence group is small.

In order to further reduce the interference between the reference signals generated by the L candidate base sequences, reduce the PAPR of the reference signals generated by the L candidate base sequences, and reduce each sequence group when the L candidate base sequences are divided into multiple sequence groups The interference between the reference signals corresponding to the base sequence in the base sequence, the relationship between L, M and N _zc includes but not limited to the following relationships:

In a scenario where the number is greatly increased, a large number of terminals in a cell need more base sequence requirements, and the terminals in the cell do not need to send uplink reference signals to different terminals in turn in a time division manner, which ensures the performance of the system.

The following uses specific embodiments to describe another reference signal processing method provided in the present application.

FIG. 5 is an interaction diagram 3 of a reference signal processing method provided by an embodiment of this application. Referring to FIG. 5, the method of this embodiment includes:

Step S401: The first node generates a reference signal according to a reference signal sequence of length M; wherein the reference signal sequence is generated from a first base sequence, and the first base sequence is generated from a first Zadoff-Chu sequence of length N _zc , Where N _zc > M and N _zc is an integer; the first base sequence is one of L candidate base sequences; the L candidate base sequences include L ₀ base sequences generated by Zadoff-Chu sequences of length N _zc and At least one base sequence generated from a Zadoff-Chu sequence of length N ₁ , 30≤L ₀ ≤L-1 and L ₀ is a positive integer; N ₁ is the largest prime number less than or equal to M or N ₁ is greater than or equal to M The smallest prime number of.

The difference between this embodiment and the previous embodiment at least includes: In addition to the L ₀ base sequences generated from Zadoff-Chu sequences of length N _zc , the L candidate base sequences in this embodiment also include Including A base sequences generated from Zadoff-Chu sequences with length N ₁ ; A≥1, L ₀ +A≤L. Optionally, the L candidate base sequences may also include L-(L ₀ +A) base sequences corresponding to Zadoff-Chu sequences of other lengths. The base sequences corresponding to L-(L ₀ +A) Zadoff-Chu sequences of other lengths can be generated from Zadoff-Chu sequences of the same or different lengths, which is not limited in the embodiment of the application.

That is, the L candidate base sequences include L ₀ base sequences generated from Zadoff-Chu sequences with length N _zc , and A base sequences generated from Zadoff-Chu sequences with length N ₁ .

Group sequence length meanings Zadoff-Chu sequence of N _x a, "the length of the base sequence N _x of Zadoff-Chu sequences generated" meaning "base sequence is of length N _x of the Zadoff-Chu sequence generated For the specific meaning of ", the meaning of "the reference signal sequence is generated by the first base sequence", please refer to the description in the embodiment shown in FIG. 3. In addition, the base sequence can also be calculated based on the root of the Zadoff-Chu sequence of length N _x , M and length N _x . That is, the base sequence is determined based on the Zadoff-Chu sequence of length N _x .

It is understandable that “the first base sequence is generated from the Zadoff-Chu sequence with length N _zc ” is not limited to the following steps in the process of generating the reference signal by the first node according to the reference signal sequence with length M: The Zadoff-Chu sequence of length N _zc generates the first base sequence. "The reference signal sequence is generated from the first base sequence" is not limited to the following steps in the process of generating the reference signal by the first node according to the reference signal sequence of length M: generating the reference signal sequence according to the first base sequence.

In one way, the roots of the Zadoff-Chu sequences in the A Zadoff-Chu sequences with length N ₁ can be determined by the following formula:

Among them, u _i ∈ {0,1,2,...,29} and v _i ∈{0,1}. Optionally, when A=30, v _i can be equal to 0 or 1, and u _i can take values between 0-29 in turn.

It can be understood that the base sequences used by different nodes to generate the reference signal sequence may be different, but the base sequences used by each node all belong to L candidate base sequences.

In another implementation manner, before the first node generates the reference signal, the first node obtains a reference signal sequence of length M. It should be understood that the first node acquiring the reference signal sequence of length M may be a reference signal sequence generated in advance by the first node by looking up the table, or the first node may generate a reference signal according to the first base sequence and a predefined rule The sequence is not limited in the embodiment of this application. Among them, the predefined rule here can be the following formula, but is not limited to the following formula:

S(m)=A·exp(jαm)·r(m), m=0,1,2,...,M-1

In the first scheme, the first node obtains the pre-generated reference signal sequence by looking up the table. The first node may store multiple reference signal sequences of length M and respective indexes of multiple reference signal sequences of length M, and the first node obtains the reference signal sequence of length M according to the index of the reference signal sequence.

The acquisition of the first base sequence in the process of generating the reference signal by the first node according to the reference signal sequence of length M will be described below.

The first node obtains the first base sequence according to the configuration information. In the wireless communication network shown in FIG. 1 (ie, the cellular mobile network communication system), if the first node is a terminal, the configuration information may be sent by the network device to the first node. At this time, the network device is the second node; if The first node is a network device, and the configuration information is determined by the network device. In the V2X communication system shown in Figure 2, when the first node and the second node are both within the coverage of the cellular mobile network, the configuration information can be sent by the network device to the first node, or it can be sent by the network device. To the second node, the second node sends to the first node. When the first node is not within the coverage of the cellular mobile network, the configuration information may be sent by the second node to the first node. It is understandable that different node configuration information may be different, and the L candidate base sequences are L base sequences corresponding to all possible values of the configuration information.

Exemplarily, the first indication information indicates the sequence index of the first Zadoff-Chu sequence for generating the first base sequence. At this time, all possible values of the configuration information may include the respective indexes of the L Zadoff-Chu sequences. Correspondingly, the first node obtains the first base sequence according to the configuration information, including: the first node obtains the first Zadoff-Chu sequence for generating the first base sequence according to the first indication information, and the first node obtains the first Zadoff-Chu sequence according to the first Zadoff -The length M of the Chu sequence and the reference signal sequence to generate the first base sequence. Wherein, in this implementation, the first base sequence is generated according to the length M of the first Zadoff-Chu sequence and the reference signal sequence. It can be understood that the first base sequence may be calculated by the first Zadoff-Chu sequence according to a predefined rule Alternatively, the first base sequence may be obtained according to the first Zadoff-Chu sequence and the second correspondence, and the second correspondence is the correspondence between the L candidate base sequences and the L Zadoff-Chu sequences. The predefined rule here can be that when M is greater than the length N _zc of the first Zadoff-Chu sequence, the first Zadoff-Chu sequence is expanded by cyclic shift to obtain the first base sequence, and when M is less than N _zc , the first base sequence is obtained by intercepting The first Zadoff-Chu sequence obtains the first base sequence. When M is equal to N _zc , the first Zadoff-Chu sequence is determined to be the first base sequence.

Exemplarily, the first indication information indicates the length N _{zc of the} first Zadoff-Chu sequence and the corresponding root q. In this case, all possible values of the configuration information may include the length and root corresponding to the L Zadoff-Chu sequences for generating L candidate base sequences; or, all the possible values of the configuration may include generating LA candidate base sequences LA is a Zadoff-Chu sequence corresponding to the length and root length and a is the a number of length of the base sequence N ₁ Zadoff-Chu sequence generator for generating a sequence of L candidate group is the N ₁ The indication information of the A roots of the Zadoff-Chu sequence (such as u value, v value) and N ₁ , where the LA candidate base sequences are the L candidate base sequences except for A by the Zadoff-Chu sequence with length N ₁ A base sequence other than the generated base sequence; or, all possible values of the configuration information may include the indication information and length of the root corresponding to the L Zadoff-Chu sequences for generating the L candidate base sequences. Correspondingly, the first node acquiring the first base sequence according to the first indication information includes: the first node acquiring the length N _zc and the root q of the first Zadoff-Chu sequence according to the first indication information, and the first node according to the N _zc , q, and M generate the first base sequence; or, the first node obtains the length N _zc and root q of the first Zadoff-Chu sequence according to the configuration information, and the first node obtains the length N _zc and root q according to N _zc , q, M and the third correspondence relationship The first base sequence is obtained, and the third correspondence is the length of L Zadoff-Chu sequences and the correspondence between roots and L Zadoff-Chu sequences.

The second embodiment: the configuration information includes second indication information and third indication information, the second indication information is used to indicate the sequence group where the first base sequence is located (for the convenience of subsequent explanation, the sequence group where the first base sequence is Called the target sequence group), the third indication information is used to indicate the first base sequence in the target sequence group.

Exemplarily, the second indication information indicates the group index or the cell index of the target sequence group, and the third indication information indicates the index of the first base sequence in the target sequence group. In this case, all possible values of the configuration information may include the group index of each group, and the index of the base sequence in each group in the respective sequence group. Correspondingly, the first node obtains the first base sequence according to the configuration information, including: the first node obtains the group index or cell index of the target sequence group according to the second indication information, and obtains the first base sequence in the target sequence according to the third indication information The group index is based on the group index or cell index of the target sequence group and the index of the first base sequence in the target sequence group to obtain the first base sequence.

For the number of candidate base sequences L: L ₀ is an integer greater than or equal to 30, and L is an integer greater than or equal to 31. Optionally, L is an integer greater than or equal to 60. Wherein, the value range of L ₀ includes but is not limited to one of the following: 30≤L ₀ ＜60, 60≤L ₀ ＜90, and L ₀ ≥90.

For the first group sequence length N _zc corresponding to the Zadoff-Chu sequence, N _zc> M. N _zc can be a prime number in the set [140,800]. That is, the value of N _zc can be one of the following: 149,151,157,163,167,173,179,181,191,193,197,199,211,223,227,229,233,239,241 , 251,257,263,269,271,277,281,283,293,307,311,313,317,331,337,347,349,353,359,367,373,379,383,389,397 , 401,409,419,421,431,433,439,443,449,457,461,463,467,479,487,491,499,503,509,521,523,541,547,557,563 , 569,571,577,587,593,599,601,607,613,617,619,631,641,643,647,653,659,661,673,677,683,691,701,709,719 , 727, 733, 739, 743, 751, 757, 761, 769, 773, 787, 797. When N _zc is a prime number in the set [140,800], the cross-correlation between the reference signals generated by the L candidate base sequences is small. In addition, when the value of N _zc is a prime number in the set [140,800], the PAPR of the reference signal generated by the L candidate base sequences is low (for example, less than 5dB), where the reference signal generated by the L candidate base sequences The lower PAPR can effectively improve the coverage of the reference signal. In addition, in order to avoid that different cells use the same base sequence to generate reference signals and cause strong inter-cell interference, in practical applications, the L candidate base sequences may be divided into multiple sequence groups that do not contain the same base sequence.
