Description

Method and device for processing reference signal

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for processing a reference signal.

Background

Sequences of uplink reference signals (such as uplink demodulation reference signals (DMRS), uplink Sounding Reference Signals (SRS)) or downlink reference signals of Long Term Evolution (LTE) and New Radio (NR) technologies are generated from a base sequence (base sequence) having a length of M. For example, if the base sequence with length M is r (M), M is 0,1,2, …, M-1, the reference signal sequence generated by the base sequence may be:

A·exp(jαm)·r(m),m＝0,1,2,…，M-1，

where M is an integer greater than 1, α is a value determined by a time domain cyclic shift value, is a real number, j is a unit of an imaginary number, and a is a complex number.

The base sequence may be generated from a Zadoff-Chu sequence of length N, such as the Zadoff-Chu sequence itself, or the Zadoff-Chu sequence may be cyclically extended or truncatedThe generated sequence. For example, a Zadoff-Chu sequence of length N is z_q(N), N-0, 1., N-1, then the length M sequence generated by the Zadoff-Chu sequence can be expressed as: z is a radical of_q(mmodN), M ═ 0, 1.., M-1. Wherein a Zadoff-Chu sequence of length N may be represented as follows:

wherein N is the length of the Zadoff-Chu sequence and is an integer greater than 1; q is the root of the Zadoff-Chu sequence, is a natural number coprime to N, and 0 < q < N.

Taking the SRS as an example, before sending the SRS, the terminal device needs to determine the SRS sequence according to the base sequence. In the 3rd generation partnership project (3 GPP) standard, various length M SRS sequences are defined. Wherein, when M is an integer greater than or equal to 36 and less than 72, 30 base sequences are respectively defined, wherein the 30 base sequences are generated by Zadoff-Chu sequences having the same length and different roots. Further, the 30 base sequences are divided into 30 groups, different groups of base sequences can be allocated to different cells, and taking M as an example 36,30 groups of base sequences are generated to be Zadoff-Chu sequences with length 31, and the relationship between the root of the Zadoff-Chu sequences and the group number of the base sequences can be referred to table 1:

TABLE 1

In this case, 1 base sequence is allocated to each cell to generate the finally transmitted SRS sequence, that is, each terminal device transmitting the SRS sequence with the same length at the same time in one cell uses the SRS sequence generated by the same base sequence. When the SRS sequences are generated using the same base sequence, terminal devices in one cell obtain orthogonality between the SRS sequences by using different time domain cyclic shifts and/or time-frequency domain resources.

For each value of M which is greater than or equal to 72, 60 base sequences are respectively defined, wherein the 60 base sequences are generated by Zadoff-Chu sequences which have the same length and different roots. Further, the 60 base sequences are divided into 30 groups, and different groups of base sequences may be allocated to different cells. Taking M-72 as an example, 30 groups of base sequences are generated by using Zadoff-Chu sequences with length 71, and the relationship between the root of the Zadoff-Chu sequences and the group number of the base sequences can be referred to table 2:

TABLE 2

At this time, each cell is allocated one sequence group each including 2 base sequences of the same length to generate a finally transmitted SRS sequence. However, in a cell, terminal devices that transmit SRS sequences with the same length on the same time-frequency resource use SRS sequences generated by the same base sequence in the sequence group corresponding to the cell. That is, in a practical system, 2 base sequences of the same base sequence group are used as hopping sequences, that is, at different times, a base sequence adopted by a terminal device can hop among the 2 base sequences in the group according to a designed pattern, which aims to randomize interference among cells.

Therefore, in the current system, only 1 base sequence is available for the SRS sequence of one cell on the same time-frequency resource. And the number of terminal devices in each cell is large (e.g., 200), the number of time domain cyclic shifts and the number of available time-frequency domain resources that can achieve better orthogonality in an actual system are limited. Therefore, the number of available SRS sequences in a cell at present is far from the number of terminal devices. This results in the need to have different terminal devices transmit SRS in turn in a time division manner, resulting in a larger SRS period, for example, 20 ms. However, the channel has a time-varying characteristic, the channel state information obtained through the SRS is easily outdated due to a large SRS period, and the channel state information during downlink data transmission is greatly different from the channel state information measured according to the SRS, which seriously affects the performance of the system.

Detailed Description

Before describing the technical solutions of the present application, the terms referred to in the present application are introduced as follows:

1. [ A, B ] represents a set consisting 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 with length M is r (M), M is 0,1,2, …, M-1, the reference signal sequence generated by the base sequence may be:

A·exp(jαm)·r(m),m＝0,1,2,…,M-1

The base sequence r (m) may be generated from a Zadoff-Chu sequence of length N, such as the Zadoff-Chu sequence itself, or a Zadoff-Chu sequence generated by cyclic extension or truncation of the Zadoff-Chu sequence. For example, a Zadoff-Chu sequence of length N is z_q(N), N-0, 1, N-1, is prepared fromThe length M sequence generated by the Zadoff-Chu sequence can be expressed as: z is a radical of_q(mmodN), M ═ 0, 1.., M-1. Wherein a Zadoff-Chu sequence of length N may be represented as follows:

That is, a length N Zadoff-Chu sequence may have N-1 roots, corresponding to N-1 base sequences of length M. Different reference signal sequences can be obtained by adopting different cyclic shift values alpha according to a base sequence generated by one root of the Zadoff-Chu sequence with the length N.

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

In a general scheme, a base sequence for generating a reference signal sequence for a device is based on a length N₁Is determined by the Zadoff-Chu sequence of (1), wherein N is₁Is the largest prime number less than or equal to M, or the smallest prime number greater than or equal to M, i.e. N₁Less than or equal to M or slightly greater than M. Then when M is small, for example, M is 36, 48, N₁And is also smaller.

And a length of N₁Is equal to N₁-1, length N₁Corresponding to the Zadoff-Chu sequence of (1)₁1 base sequence, then smaller at M, N₁Also in the case of smaller, based on the length N₁The number of available base sequences determined by the Zadoff-Chu sequence is small, so that the requirement of a large number of terminals of the current system cannot be met, different terminals need to send reference signals in turn in a time division mode, and a large reference signal period is caused. The channel has time-varying characteristic, and the larger reference signal period leads the channel state information obtained by the reference signal to be easily outdated, namely the channel state information in data transmission is identical to the channel state information previously obtained according to the reference signalThe channel state information measured by the number is very different, and the performance of the system is seriously influenced.

The V2X communication is a basic technology and a key technology applied in a scene with a very high requirement on communication delay in the future, such as intelligent automobiles, automatic driving, intelligent transportation systems, and the like, for high-speed devices represented by vehicles.

As shown in fig. 2, the vehicles or vehicle components communicate with each other via V2V. The vehicle or the vehicle component can broadcast the information of the speed, the driving direction, the specific position, whether the emergency brake is stepped on and the like of the vehicle or the vehicle component to surrounding vehicles, and drivers of the surrounding vehicles can better sense the traffic condition outside the sight distance by acquiring the information, so that the dangerous condition is pre-judged in advance and avoided; the vehicle or vehicle component communicates with a roadside infrastructure, which may provide access to various service information and data networks for the vehicle or vehicle component, via V2I. The functions of non-stop charging, in-car entertainment and the like greatly improve the traffic intelligence. Roadside infrastructure, for example, roadside units (RSUs) include two types: one is a terminal equipment type RSU. Since the RSU is distributed on the roadside, the RSU of the terminal equipment type is in a non-mobile state, and the mobility does not need to be considered; the other is a RSU of network device type. The RSU of this network device type may provide timing synchronization and resource scheduling to the vehicle or vehicle component in communication with the network device. The vehicle or vehicle component communicates with the person via V2P; the vehicle or vehicle component communicates with the network via V2N.

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

The reference signal processing method according to the embodiment of the present application is explained below.

Fig. 3 is an interaction of a reference signal processing method according to an embodiment of the present application. Referring to fig. 3, the method of the present embodiment includes:

step S201, a first node generates a reference signal according to a reference signal sequence with the length of M; wherein the reference signal sequence is generated by a first base sequence with a length of N_zcOf a Zadoff-Chu sequence of (1), wherein N is_zc> M and N_zcIs an integer; the first base sequence is one of L candidate base sequences; l is not less than 31 and L is an integer.

In this embodiment, the L candidate base sequences include L₁Is composed of length N_zcBase sequence generated from Zadoff-Chu sequence of (1), L₁Not less than 1, and L₁≤L。

At L₁When L, L candidate base sequences include L sequences of length N_zcA base sequence generated from the Zadoff-Chu sequence of (1). At L₁If < L, L candidate base sequences other than L₁Is composed of length N_zcThe base sequence generated by the Zadoff-Chu sequence also comprises L-L₁Base sequences generated from Zadoff-Chu sequences of other lengths. L-L₁Base sequences generated from Zadoff-Chu sequences of other lengths may be composed of Zadoffs of the same or different lengthsAnd f-Chu sequences are generated, which is not limited in the embodiment of the present application. Other lengths here not equal to N_zcAnd is not equal to N₁。

Wherein, the length of the ring is N_xThe base sequence generated by the Zadoff-Chu sequence is N in length_xThe Zadoff-Chu sequence of (1) and the specific meanings of the two are as follows: the sequence of the motif is of length N_xThe Zadoff-Chu sequence itself, or the base sequence is composed of a length N_xThe Zadoff-Chu sequence is obtained by cyclic shift expansion or truncation. It will be appreciated that the base sequence may also be based on length N_xM and a length of N_xThe root of the Zadoff-Chu sequence of (a) was calculated. I.e., the base sequence is based on a length of N_xDetermined by the Zadoff-Chu sequence of (a). It is understood that "the first base sequence is composed of a length N_zcThe Zadoff-Chu sequence generation is not limited in the process that the first node generates the reference signal according to the reference signal sequence with the length of M, and the following steps are necessarily present: based on length N_zcDetermining a first base sequence, or according to a length N, of the Zadoff-Chu sequence_zcGenerating a first base sequence. In other words, according to the length N_zcGenerating the first base sequence is an optional step.

The reference signal sequence is generated from a first base sequence, and it is understood that the reference signal sequence can be calculated from the first base sequence and the cyclic shift value α by a predefined rule; alternatively, the reference signal sequence may be obtained according to a first base sequence and a first correspondence relationship, where the first correspondence relationship is a correspondence relationship between the L candidate base sequences, the cyclic shift value α, and the reference signal sequence. It is understood that the base sequences used by different nodes to generate the reference signal sequence may not be the same, but the base sequences used by each node belong to L candidate base sequences. It is to be understood that "the reference signal sequence is generated by the first base sequence" does not limit the following steps in the process of generating the reference signal by the first node according to the reference signal sequence with the length M: and generating a reference signal sequence according to the first base sequence.

In the 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 a V2X communication system, the reference signal may be a sidelink reference signal. The reference signal of the present embodiment includes, but is not limited to, SRS, DMRS.

In another embodiment, before the first node generates the reference signal, the first node acquires a reference signal sequence with a length M. It should be understood that, the first node acquires the reference signal sequence with the length M, may obtain the reference signal sequence generated in advance by the first node through table lookup, or may generate the reference signal sequence according to the first base sequence and a predefined rule, which is not limited in this embodiment of the present application. The predefined rule here may be, but is not limited to, the following formula:

S(m)＝A·exp(jαm)·r(m),m＝0,1,2,…,M-1

wherein s (m) is a reference signal sequence, r (m) is a first base sequence, and α is a cyclic shift value for generating the reference signal sequence.

In the first scheme, the first node obtains a pre-generated reference signal sequence through table lookup. The first node may store a plurality of reference signal sequences with a length of M and respective indexes of the plurality of reference signal sequences with the length of M, and the first node acquires the reference signal sequence with the length of M according to the indexes of the reference signal sequences.

In a second scheme, the generating, by the first node, a reference signal sequence with a length M specifically includes: the first node generates a length-M reference signal sequence according to a length-M first base sequence. Wherein the first base sequence is composed of a length N_zcGenerated from the Zadoff-Chu sequence of (1).

In the V2X communication system shown in fig. 2, when the first node and the second node are both in the coverage area of the cellular mobile network, the configuration information may be sent to the first node by the network device, or may be sent to the first node by the second node after the network device is sent to the second node. The configuration information may be sent by the second node to the first node when the first node is not within the coverage area of the cellular mobile network. It is understood that L candidate base sequences are L base sequences corresponding to all possible values of the configuration information.

Another reference signal processing method provided in the present application is described below with specific examples.

Fig. 5 is an interaction diagram of a reference signal processing method according to an embodiment of the present application. Referring to fig. 5, the method of the present embodiment includes:

step S401, the first node generates a reference signal according to a reference signal sequence with the length of M; wherein the reference signal sequence is generated by a first base sequence with a length of N_zcIs generated by a first Zadoff-Chu sequence of (1), wherein N is_zc> M and N_zcIs an integer; the first base sequence is one of L candidate base sequences;the L candidate base sequences include L₀Is composed of length N_zcAnd at least one base sequence generated from a length N of the Zadoff-Chu sequence₁A base sequence generated by the Zadoff-Chu sequence of (1), L is more than or equal to 30₀L-1 and L is not more than₀Is a positive integer; n is a radical of₁Is the maximum prime number less than or equal to M or N₁Is the smallest prime number greater than or equal to M.

The difference between this embodiment and the previous embodiment at least includes: in addition to L, L candidate base sequences in this embodiment include₀Is composed of length N_zcThe Zadoff-Chu sequence of (a) includes, in addition to a base sequence generated from the Zadoff-Chu sequence of (a), A sequences of length N₁A base sequence generated from the Zadoff-Chu sequence of (1); a is more than or equal to 1 and L₀L is less than or equal to + A. Optionally, the L candidate base sequences may further include L- (L)₀+ A) base sequences corresponding to Zadoff-Chu sequences of other lengths. L- (L)₀+ A) base sequences corresponding to Zadoff-Chu sequences of other lengths may be generated from Zadoff-Chu sequences of the same or different lengths, which is not limited in the embodiment of the present application.

That is, L candidate base sequences include L₀Is composed of length N_zcA base sequences of length N₁A base sequence generated from the Zadoff-Chu sequence of (1).

Base sequence and length N_xMeaning of Zadoff-Chu sequence of "by length N_x"the" base sequence "is a base sequence of length N_xThe "reference signal sequence is generated from the first base sequence" in the specific sense of "generated from the Zadoff-Chu sequence of (a), see the explanation in the embodiment shown in fig. 3. In addition, the base sequence may also be based on length N_xM and a length of N_xThe root of the Zadoff-Chu sequence of (a) was calculated. I.e., the base sequence is based on a length of N_xDetermined by the Zadoff-Chu sequence of (a).

It is understood that "the first base sequence is composed of a length N_zcThe Zadoff-Chu sequence generation is not limited to the following steps in the process that the first node generates the reference signal according to the reference signal sequence with the length of M: according to lengthIs N_zcGenerating a first base sequence. The "reference signal sequence is generated from the first base sequence" does not limit the following steps in the process of generating the reference signal from the reference signal sequence with the length M by the first node: and generating a reference signal sequence according to the first base sequence.

In one mode, the above-mentioned a lengths N can be determined by the following formula₁Root of Zadoff-Chu sequence in Zadoff-Chu sequences of (1):

wherein u is_i∈{0,1,2,...,29}，v_iE {0,1 }. Optionally, when a is 30, v_iMay be equal to 0 or 1, u_iThe values can be sequentially between 0 and 29.

It is understood that the base sequences used by different nodes to generate the reference signal sequence may not be the same, but the base sequences used by each node belong to L candidate base sequences.

S(m)＝A·exp(jαm)·r(m),m＝0,1,2,…,M-1

The following describes the acquisition of a first base sequence in the process of generating a reference signal by a first node according to a reference signal sequence with a length M.

And the first node acquires the first base sequence according to the configuration information. In the wireless communication network shown in fig. 1 (i.e. the cellular mobile network communication system), if the first node is a terminal, the configuration information may be sent to the first node by the network device, and at this time, the network device is the second node; if the first node is a network device, the configuration information is determined by the network device. In the V2X communication system shown in fig. 2, when the first node and the second node are both in the coverage area of the cellular mobile network, the configuration information may be sent by the network device to the first node, or sent by the network device to the second node, which is sent by the second node to the first node. The configuration information may be sent by the second node to the first node when the first node is not within the coverage area of the cellular mobile network. It can be understood that different node configuration information may not be the same, and L candidate base sequences are L base sequences corresponding to all possible values of the configuration information.

Illustratively, the first indication information indicates a sequence index of a first Zadoff-Chu sequence generating the first base sequence. At this time, all possible values of the configuration information may include respective corresponding indexes of the L Zadoff-Chu sequences. Correspondingly, the first node acquires a first base sequence according to the configuration information, and the method comprises the following steps: and the first node acquires a first Zadoff-Chu sequence used for generating a first base sequence according to the first indication information, and generates the first base sequence according to the first Zadoff-Chu sequence and the length M of the reference signal sequence. In this embodiment, the first base sequence is generated according to the length M of the first Zadoff-Chu sequence and the reference signal sequence, and it is understood that the first base sequence may be calculated by the first Zadoff-Chu sequence according to a predefined rule, or the first base sequence may be calculated according to the first Zadoff-Chu sequence and a second correspondence relationship, where the second correspondence relationship is a correspondence relationship between the L candidate base sequences and the L Zadoff-Chu sequences. The predefined rule here may be that at M is larger than the length N of the first Zadoff-Chu sequence_zcThen, a first Zadoff-Chu sequence is expanded by cyclic shift to obtain a first base sequence, and M is less than N_zcThen, a first base sequence is obtained by intercepting a first Zadoff-Chu sequence, and M is equal to N_zcThen, the first Zadoff-Chu sequence is determined to be the first base sequence.

Illustratively, the first indication information indicates a length N of the first Zadoff-Chu sequence_zcAnd a corresponding root q. In this case equipped withAll possible values of the setting information can include lengths and roots corresponding to L Zadoff-Chu sequences for generating L candidate base sequences; or, all possible values of the configuration may include lengths and roots corresponding to L-a Zadoff-Chu sequences for generating L-a candidate base sequences, and a length N for generating a of the L candidate base sequences₁A base sequences generated from the Zadoff-Chu sequences have a length of N₁The indication information (such as u value, v value) and N of A roots of the Zadoff-Chu sequence₁Wherein, the L-A candidate base sequences are the other than A candidate base sequences with the length of N₁A base sequence other than the base sequence generated from the Zadoff-Chu sequence of (1); or, all possible values of the configuration information may include indication information and lengths of roots corresponding to L Zadoff-Chu sequences that generate the L candidate base sequences. Correspondingly, the first node acquires the first base sequence according to the first indication information, and the method comprises the following steps: the first node acquires the length N of the first Zadoff-Chu sequence according to the first indication information_zcAnd a root q according to which the first node is_zcQ and M generate a first base sequence; or the first node acquires the length N of the first Zadoff-Chu sequence according to the configuration information_zcAnd a root q, the first node being according to N_zcQ, M and a third corresponding relation to obtain a first base sequence, wherein the third corresponding relation is the corresponding relation between the length and the root of the L Zadoff-Chu sequences and the 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 a sequence group in which the first base sequence is located (for convenience of subsequent explanation, the sequence group in which the first base sequence is located is referred to as a target sequence group), and the third indication information is used to indicate the first base sequence in the target sequence group.

Illustratively, the second indication information indicates a group index or a cell index of the target sequence group, and the third indication information indicates an 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 the respective group, the index of the base sequence in each group within the respective sequence group. Correspondingly, the first node acquires the first base sequence according to the configuration information, and the method includes that the first node acquires a group index or a cell index of a target sequence group according to the second indication information, acquires an index of the first base sequence in the target sequence group according to the third indication information, and acquires the first base sequence according to the group index or the cell index of the target sequence group and the index of the first base sequence in the target sequence group.
