Description

Technical Field

[0001] The present application relates to a communication system, and more particularly, to a signal processing method and apparatus. Background Art

[0002] In the long term evolution (LTE) system, the physical uplink shared channel (PUSCH) and PUCCH use the demodulation reference signal (DMRS) for channel estimation and thus signal demodulation. In the LTE system, the base sequence of the uplink DMRS can be directly mapped to the resource element without any coding processing. In LTE, the uplink DMRS reference sequence is defined as a cyclic shift of the base sequence, and the base sequence of the uplink DMRS is obtained by cyclic expansion of the Zadoff-Chu sequence (ZC sequence). The ZC sequence is a sequence that satisfies the constant amplitude zero auto-correlation (CAZAC) sequence property.

[0003] In the new radio access technology (NR), uplink transmission signals support discrete Fourier transform spread OFDM (DFT-s-OFDM) waveforms. Uplink transmission signals use the π / 2BPSK modulation method, and the uplink transmission signals after DFT transformation can be filtered in the frequency domain. When the uplink transmission signal uses π / 2BPSK modulation, sequences based on Gold sequences or computer-generated sequences (CGS) can be used. Currently, NR plans to support DFT-s-OFDM, and the DMRS waveform uses the ZC sequence. It is also planned that NR will support uplink transmission signals using π / 2BPSK modulation using the ZC sequence for the DMRS.

[0004] However, if the uplink DMRS uses a ZC sequence, the DMRS peak-to-average power ratio (PAPR) will be higher than the corresponding uplink transmission signal PAPR, resulting in out-of-band DMRS spurious emissions and in-band signal loss, affecting channel estimation performance or limiting uplink coverage. Furthermore, when the uplink DFT-s-OFDM DMRS waveform uses π / 2 BPSK modulation and a filter, if the uplink DFT-s-OFDM DMRS waveform uses a Gold sequence-based sequence or CGS, if appropriate filtering is not performed, the frequency flatness of the sequence will be poor, which is not conducive to channel estimation. If the uplink DFT-s-OFDM DMRS waveform uses a ZC sequence, the DMRS peak-to-average power ratio (PAPR) will be higher than the PAPR of the transmitted data, resulting in out-of-band spurious emissions of the pilot signal and in-band signal loss, affecting channel estimation performance or limiting uplink coverage.

[0005] In other words, the existing DMRS sequence cannot meet the current communication application environment. In addition, the sequence used by the existing reference signal (eg, DMRS) for PDSCH cannot meet the current communication application environment using PUSCH to send signals.

The network device can be a base station (base transceiver station, BTS) in a global system for mobile communications (GSM) system or code division multiple access (CDMA), or a base station (NodeB, NB) in a wideband code division multiple access (WCDMA) system, or an evolved base station (eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (CRAN) scenario, or the network device can be a relay station, an access point, a vehicle-mounted device, a wearable device, a network device in a future 5G network, or a network device in a future evolved PLMN network, etc., and the embodiment of the present application is not limited.

[0264] In an embodiment of the present application, a terminal device or a network device includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also called main memory).

The application layer includes applications such as browsers, address books, word processing software, and instant messaging software. In addition, the embodiment of the present application does not specifically limit the specific structure of the execution subject of the method provided in the embodiment of the present application. As long as it is possible to communicate according to the method provided in the embodiment of the present application by running a program that records the code of the method provided in the embodiment of the present application, for example, the execution subject of the method provided in the embodiment of the present application can be a terminal device or a network device, or a functional module in a terminal device or a network device that can call a program and execute the program.

[0265] In addition, various aspects or features of the present application can be implemented as methods, devices or products using standard programming and / or engineering techniques. The term "product" as used in this application covers computer programs that can be accessed from any computer-readable device, carrier or medium.

[0266] Figure 1 It is a schematic diagram of a communication system of the present application. Figure 1 The communication system in the embodiment may include at least one terminal (e.g., terminal 10, terminal 20, terminal 30, terminal 40, terminal 50, and terminal 60) and a network device 70. The network device 70 is configured to provide communication services for the terminal and access the core network. The terminal may access the network by searching for synchronization signals, broadcast signals, etc. sent by the network device 70, thereby communicating with the network. Figure 1 The terminals 10, 20, 30, 40, and 60 in the network can perform uplink and downlink transmission with the network device 70. For example, the network device 70 can send downlink signals to the terminals 10, 20, 30, 40, and 60, and can also receive uplink signals sent by the terminals 10, 20, 30, 40, and 60.

[0267] In addition, the terminal 40 , the terminal 50 , and the terminal 60 may also be considered as a communication system. The terminal 60 may send downlink signals to the terminal 40 and the terminal 50 , and may also receive uplink signals sent by the terminal 40 and the terminal 50 .

[0268] In conventional schemes, a 6-length DMRS sequence is used to support PUSCH transmission in a frequency domain bandwidth of 12 subcarriers. The 6-length DMRS sequence is mapped onto 6 equally spaced subcarriers, for example, onto a bandwidth occupied by a single subcarrier. The 6-length DMRS sequence is any set of elements φ(0), ..., φ(5) in Table 1. The 6-length DMRS sequence s(n) is transformed into the sequence y(m), where y(n) = [s(n)s(n)], i.e., y(n) in y(n).

[0269] In traditional schemes, in order to support PUSCH transmission with a frequency domain bandwidth of 1RB containing 12 subcarriers, the DMRS sequence is determined based on the CGS sequence corresponding to the comb-2 structure in the frequency domain. That is, the base sequence in the time domain is repeated twice, and then OCC [+1, +1] and [+1, -1] are used for the repeated time domain base sequence respectively, and then a DFT transform is performed. Among them, in order to ensure low PAPR characteristics, good frequency domain flatness, good time domain autocorrelation characteristics, and low sequence cross-correlation characteristics, the modulation method used by the DMRS sequence is usually a high-order modulation method. For example, the sequence generation method using 8PSK is: s(n) = e jφ(n)п / 8 ,0≤n≤5, where φ(n) can be determined according to Table 1.

[0270] Table 1

[0271]

[0272]

[0273] Among them, the mapping of DMRS in the frequency domain adopts the comb-2 structure as follows Figure 2 As shown, for a certain user's PUSCH, DMRS only occupies odd subcarriers or even subcarriers. For the system, the PUSCHs of other users scheduled at the same time can occupy another subcarrier group.

[0274] The sequence shown in Table 1 is repeated [+1+1] and [+1-1], and then transformed into the frequency domain for frequency domain filtering. The final output sequence value on each subcarrier is shown in Table 2. The above transformation process is as follows: Figure 3 For example, a base sequence s with length N / 2 N / 2 Repeat to get s (0) =[s N / 2 ,s N / 2 ] and s (1) =[s N / 2 ,-s N / 2 ], then s (0) and s (1) After DFT transformation, we get a sequence s of length N. (0) =DFT(s (0) ) will only take up Figure 2 Even subcarriers shown, s (1) =DFT(s (1) ) will only occupy Figure 2 Odd subcarriers are shown.

[0275] As shown in Table 2 below and Table 1 above, a 6-length sequence s can be searched so that the PAPR of the sequence after [+1+1] repetitions is lower than the PAPR values ​​in Table 1. However, after the sequence s after [+1-1] repetitions, the PAPR is higher than the PAPR values ​​in Table 1. In other words, conventional solutions cannot find a suitable sequence such that the PAPR values ​​after [+1+1] repetitions and the PAPR values ​​after [+1-1] repetitions are both lower than the PUSCH PAPR values.

[0276] Table 2

[0277]

[0278]

[0279] In another traditional solution, a 6-length DMRS sequence is used to generate DMRS for PUSCH / PUCCH with a frequency domain bandwidth of 12 subcarriers, wherein the 6-length DMRS sequence is mapped on 6 equally spaced subcarriers, for example, mapped on the bandwidth occupied by 1 subcarrier, that is, there is only one subcarrier carrying DMRS on every two consecutive subcarriers. A 6-length DMRS sequence is generated according to any group of elements Φ(0), ..., Φ(5) in Table 1a, and the generation method is: after Φ(0), ..., Φ(5) is modulated by 8PSK, it is mapped to odd-numbered subcarriers and even-numbered subcarriers in the frequency domain through different repetition methods. Assuming that the number of the starting subcarrier occupied by the DMRS is 0, the DMRS sequence can be mapped to the even-numbered subcarriers by performing DFT transformation after the repetition method of {Φ(0), ..., Φ(5), Φ(0), ..., Φ(5)}, and the DMRS sequence can be mapped to the odd-numbered subcarriers by performing DFT transformation after the repetition method of {Φ(0), ..., Φ(5), -Φ(0), ..., -Φ(5)}.

[0280] Table 1a

[0281]

[0282]

[0283] Among them, the mapping of DMRS in the frequency domain adopts the comb-2 structure as follows Figure 2 As shown, for uplink transmission data of a certain user, DMRS only occupies odd subcarriers or even subcarriers. For the system, DMRS of uplink transmission data of other users scheduled at the same time can occupy another subcarrier group.

[0284] The sequence shown in Table 1a is modulated and repeated in different ways, and then transformed into the frequency domain through DFT and filtered in the frequency domain. The PAPR value of the sequence finally obtained is shown in Table 2a. The above transformation process is as follows: Figure 3 For example, a base sequence s with a length of N / 2 after sequence modulation N / 2 Repeat to get s (0) =[s N / 2 ,s N / 2 ] and s (1) =[s N / 2 ,-s N / 2 ], then s (0) and s (1) After DFT transformation, we get a sequence s of length N. (0) =DFT(s (0) ) will only occupy Figure 2 Even subcarriers shown, s (1) =DFT(s (1) ) will only occupy Figure 2 Odd subcarriers are shown.

[0285] From the following Table 2a and the above Table 1a, it can be seen that the base sequence s N / 2 After the repetition of {Φ(0),...,Φ(5),-Φ(0),...,-Φ(5)}, the PAPR is significantly higher than the PAPR value of the data.

[0291] Figure 4 A schematic flowchart of signal processing according to an embodiment of the present application is shown.

[0292] In the embodiments of the present application, the transmitting end may be a terminal and the corresponding receiving end may be a network device, or the transmitting end may be a network device and the receiving end may be a terminal. The following embodiments are described using the transmitting end as a terminal and the receiving end as a network device as an example, but the present application does not limit this.

[0293] 401. The terminal determines a first frequency domain resource, which includes K subcarriers numbered k, where k = u + L*n + delta, n = 0, 1, ..., K-1, L is an integer greater than or equal to 2, delta∈{0, 1, ..., L-1}, u is an integer, and the subcarrier number is numbered in order from low to high or from high to low in frequency.

[0294] Specifically, when n is 0, 1, ..., K-1, the subcarriers obtained according to k = u + L*n + delta can form a comb structure. Wherein, k is the subcarrier number, u can be the subcarrier number of the first subcarrier in the K subcarriers, and the value of L can be determined by the comb structure. For example, for the comb-2 structure (such as Figure 2 As shown), L is 2; for the structure of comb-4 (as shown Figure 5 As shown), L is 4. Delta can be any value among 0, 1, ..., L-1. When the value of delta is different, the first frequency domain resource obtained is also different, that is, different delta values ​​correspond to different comb-tooth subcarrier combinations. For example, Figure 2 As shown, when delta=0, the first frequency domain resource may include the subcarrier corresponding to comb tooth 1; when delta=1, the first frequency domain resource may include the subcarrier corresponding to comb tooth 2. The respective values ​​here refer to the case where n is 0, 1, ..., K-1.

[0295] It should be understood that the frequency domain resources in the embodiments of the present application are described using "subcarriers" as an example, but the frequency domain resources can also be carriers or other frequency domain units, and the present application does not limit this.

[0296] It should also be understood that the value of L may take other values ​​depending on the comb-tooth structure comb-L, and this application does not limit this.

[0297] It should be understood that the above-mentioned step of determining the first sequence may be optional and may be replaced by other steps. In one embodiment, before generating the reference signal, the method further includes: determining the first sequence based on the value of the delta. Specifically, it may be based on storing a mapping relationship, which may be stored after being configured by other devices or apparatuses, or may be predefined. The mapping relationship may be a mapping relationship between a delta and a first sequence, or a parameter in a generation formula. In another embodiment, the first sequence may also be generated directly based on the value of delta, wherein the first sequence is associated with the value of delta.

[0298] In another embodiment, the reference signal is sent on a first frequency domain resource, and the first frequency domain resource includes a first subcarrier set, and the subcarriers of the first subcarrier set have a fixed carrier spacing between them, such as the comb-shaped form described above. For example, the subcarrier spacing in the first subcarrier set is 1 subcarrier. Taking 6 as an example, the first subcarrier set is {a0, a1, a2, a3, a4, a5}. If the spacing is 1 subcarrier, then the subcarrier set can be arranged from small to large in the frequency domain as {a0, b, a1, c, a2, d, a3, e, a4, f, a5, g}. Among them, b, c, d, e, f, g are other subcarriers. When determining the first frequency domain resource, the first sequence to be used is determined based on the offset value of the first subcarrier set. The offset value can be a relative offset value or an absolute offset value. In one embodiment, if b, c, d, e, f, g is a second subcarrier set, constituting or partially constituting a second resource, that is, b, c, d, e, f, g are {b0, b1, b2, b3, b4, b5} respectively, then the subcarrier set is arranged from small to large in the frequency domain as {a0, b0, a1, b1, a2, b2, a3, b3, a4, b4, a5, b5}. According to the relative offset value, since the positions of the starting subcarriers of the first subcarrier set and the second subcarrier set are a0 and b0, a0 can be configured to generate the first sequence and b0 can be configured to generate the second sequence (similar to the first sequence, which is also the first sequence of b0 for b0), that is, determined according to the relative position of the starting position of the first frequency domain resource. Since the above two subcarrier sets are arranged in a comb-tooth shape, the first sequence and the second sequence can also be determined directly according to the positions of the two subcarrier sets. The relative position can be confirmed by comparison, and the absolute position can be confirmed by calculation, for example, directly based on a parameter in a preset calculation rule (similar to delta in the above embodiment), or directly based on the association between a parameter and the first sequence. For example, in this embodiment, k = u + L*n + delta, when delta = 0, it corresponds to the first sequence, and when delta = 1, it corresponds to the second sequence. In this way, when (or before) sending the reference signal, the transmitter can directly determine which first sequence should be used to generate the reference signal at which position based on the resources corresponding to each reference signal in the above formula.

[0299] In another embodiment, it can be directly calculated based on an offset value. For uplink data transmission, for example, when transmission precoding is not enabled:

[0300] The transmission sequence r(m) can be first mapped to the intermediate value according to the following relationship

[0301]

[0302]

[0303] k′=0,1

[0304]

[0305] n=0,1,...

[0306] j=0,1,...,υ-1

[0307] When transmit precoding is enabled:

[0308] The transmission sequence r(m) can be mapped to the intermediate value according to the following relationship

[0309]

[0310] k=4n+2k′+Δ

[0311] k′=0,1

[0312]

[0313] n=0,1,...

[0314] The method of mapping sequences to frequency domain resources in the present invention is applicable to the above-mentioned configuration Type 1.

[0315] Optionally, the intermediate value is a signal, which is mapped to a time-frequency resource consisting of k subcarriers and 1 OFDM symbol after transformation.

[0316] The configuration mode (configuration type) can be configured through high-level signaling, such as DMRS-UplinkConfig, k' and Δ are both (In one embodiment, Δ is the delta in the above embodiment.) When k′ or Δ is When it doesn't correspond, The value of Δ may satisfy the following relationship (in one embodiment, for the first configuration type 1):

[0317]

[0318]

[0319] (In one embodiment, for the first configuration type 2):

[0320]

[0321] Optionally, the above method is also applicable to downlink data.

[0322] Optionally, according to the above association relationship, the embodiment of the present invention is based on the above And the CDM group directly determines the first sequence.

[0323] Optionally, based on the above association relationship, an embodiment of the present invention directly determines the first sequence according to the time-frequency resources of the first signal.

[0324] Optionally, there is at least one first sequence group, characterized in that, with the same sequence length, the same first sequence group includes two different sequences.

[0325] In one embodiment, L=2, K=6, n=0, 1, 2, 3, 4, 5, and delta=0.

[0326] Specifically, L=2, that is, the comb structure is comb-2. K=6, that is, the first frequency domain resource includes 6 subcarriers. Combined with n=0,1,2,3,4,5, delta=0, k=u+L*n+delta, the terminal can determine that the first frequency domain includes subcarriers at odd positions, that is, Figure 2 In addition, from K=6 and L=2, it can be known that the first frequency domain resources may include subcarriers at odd positions among the 12 subcarriers in an RB.

[0327] In another embodiment, if L=2, K=6, n=0, 1, 2, 3, 4, 5, delta=1, the first frequency domain resource may include: Figure 2 The subcarrier shown by the comb tooth 2.

[0328] 402. The terminal determines a first sequence according to the value of delta, where different values ​​of delta correspond to different first sequences, and the length of the first sequence is K.

[0329] Specifically, the length of the first sequence is K, i.e., the first sequence includes K elements. Different delta values ​​may correspond to different sequences. For example, multiple delta values ​​may have a one-to-one mapping relationship with multiple sequences. In this way, the terminal can determine the sequence corresponding to a particular delta value based on this mapping relationship. It should be noted that this mapping relationship can be expressed in the form of a list.

[0330] Optionally, the first sequence is not a BPSK modulated sequence and is not a pi / 2BPSK modulated sequence.

[0331] Optionally, the first sequence is a sequence modulated by any one of 8PSK, 16PSK or 32PSK.

[0332] Specifically, different modulation modes correspond to different numbers of sequences. The number of sequences corresponding to any one of 8PSK, 16PSK or 32PSK modulation is greater than the number of sequences corresponding to the modulation mode pi / 2BPSK. This helps to select sequences with lower correlation for frequency domain resources with different comb teeth, thereby improving the efficiency of communication using frequency domain resources that do not pass through the comb teeth.

[0333] In one embodiment, the terminal may determine the first sequence group according to the value of the delta.

[0334] Specifically, the frequency domain resources corresponding to different delta values ​​may be different subcarrier combinations, for example, Figure 2 As shown, if delta = 0, the first frequency domain resource includes the subcarriers shown by comb tooth 1; if delta = 1, the first frequency domain resource includes the subcarriers shown by comb tooth 2. Multiple delta values ​​are mapped to multiple sequence groups, so that the terminal can determine the value of a certain delta (for example, the first delta) to determine the first sequence group based on the mapping relationship.

[0335] Different modulation modes correspond to different numbers of sequences. The number of sequences corresponding to any one of 8PSK, 16PSK, or 32PSK modulation is greater than the number of sequences corresponding to the pi / 2BPSK modulation mode. This helps to lower the PAPR of the DMRS sequence carried on the frequency domain resources with different comb teeth, thereby avoiding out-of-band spurious emissions and in-band signal loss, or improving uplink coverage; at the same time, it can also ensure that the autocorrelation, frequency domain flatness, and other characteristics of the DMRS sequence carried on the frequency domain resources with different comb teeth are low, thereby improving the channel estimation performance based on the DMRS.

[0336] In one embodiment, the terminal may determine the first sequence according to the value of the delta and the cell identifier or the sequence group identifier.

[0337] Specifically, the frequency domain resources corresponding to different delta values ​​may be different subcarrier combinations, for example, Figure 2 As shown, if delta = 0, the first frequency domain resource includes the subcarriers shown by comb tooth 1; if delta = 1, the first frequency domain resource includes the subcarriers shown by comb tooth 2. Multiple delta values ​​have a mapping relationship with multiple sequence sets. This mapping relationship can be predefined, so that the terminal can determine a sequence set from the multiple sequence sets based on the mapping relationship and the delta value at the current transmission time (for example, the first delta), and the sequence set corresponds to the first delta. The terminal determines a sequence in the sequence set based on the cell identifier or sequence group identifier as the sequence for generating the DMRS.

[0338] Optionally, the terminal may determine the first sequence group according to a cell identifier or a sequence group identifier.

[0339] Specifically, both the terminal and the network device pre-store multiple sequence groups, each of which corresponds to a cell identifier or sequence group identifier. Based on the network device's configuration information, which includes the cell identifier or sequence group identifier, the terminal can determine the sequence group used to transmit the DMRS. This allows different cells to use different sequence groups, reducing inter-cell signal interference. Furthermore, multiple delta values ​​have a pre-defined mapping relationship with multiple sequences in the sequence group. Based on the delta value, the terminal determines a sequence from the sequence group as the sequence for generating the DMRS.

[0340] Optionally, the terminal may determine the first sequence group according to a cell identifier or a sequence group identifier.

[0341] Specifically, the terminal can group sequences with the same cell identifier into a sequence group. That is, different sequence groups serve different cells. The terminal can also agree on a sequence group identifier with the network device, with different sequence group identifiers corresponding to different sequence groups. In this way, the terminal can determine the corresponding sequence group based on the sequence group identifier configured by the network device. This means that the terminal can select a sequence from the appropriate sequence group to generate a reference signal, thereby accurately demodulating the first signal and improving data transmission quality.

[0342] Optionally, the terminal receives indication information, where the indication information is used to indicate a sequence in each of at least two sequence groups for generating a reference signal. Correspondingly, the network device sends the indication information.

[0343] Specifically, the network device can send indication information to the terminal, indicating the sequence in each sequence group of at least two sequence groups through the indication information, that is, further notifying the terminal which sequence in the sequence group to use, so that the terminal generates a reference signal according to the sequence indicated by the indication information. Compared with configuring the indication information for selecting a sequence from each sequence group, the embodiment of the present application can save signaling overhead. It should be understood that steps 401 and 402 are two optional steps.

[0344] 403. The terminal generates a reference signal of a first signal according to the first sequence, where the first signal is a pi / 2 BPSK modulated signal.

[0345] Specifically, the terminal may respectively map the K elements of the first sequence to K subcarriers on the first frequency domain resources to obtain the reference signal.

[0346] It should be noted that the reference signals mapped to the frequency domain resources corresponding to different delta values ​​can be different reference signals of the same terminal or reference signals of different terminals, and this application does not limit this.

[0347] It should be understood that the first signal may be data or signaling modulated by pi / 2BPSK, which is not limited in this application.

[0348] It should also be understood that the reference signal can be a demodulation reference signal (DMRS), UCI, SRS and PTRS, or it can also be acknowledgment (ACK) information, or negative acknowledgment (NACK) information, or uplink scheduling request (SR) information, which is not limited in this application.

[0349] Optionally, when delta=0, the reference signal for generating the first signal includes:

[0350] Performing a discrete Fourier transform on the elements of the sequence {z(t)} to obtain a sequence {f(t)}, where t=0, ..., L*K-1, wherein when t=0, 1, ..., L*K-1, z(t)=x(t mod K), and x(t) represents the first sequence;

[0351] The reference signal is generated by mapping the elements numbered L*p+delta in the sequence {f(t)} to the subcarriers numbered u+L*p+delta, where p=0, ..., K-1.

[0352] Optionally, when L=2 and delta=1, the reference signal for generating the first signal includes:

[0353] Performing a discrete Fourier transform on the elements of the sequence {z(t)} to obtain a sequence {f(t)}, where t=0, ..., L*K-1, wherein z(t)=x(t) when t=0, ..., K-1, and z(t)=-x(t mod K) when t=K, ..., L*K-1, where x(t) represents the first sequence;

[0354] The elements numbered L*p+delta in the sequence {f(t)} are respectively mapped to the subcarriers numbered u+L*p+delta to generate the reference signal, where p=0, ..., K-1.

[0355] Optionally, when L=4, the reference signal for generating the first signal includes:

[0356] The elements in the sequence {z(t)} are subjected to discrete Fourier transform to obtain the sequence {f(t)}, t=0,…,4K-1, where when t=0,1,…,4K-1, Where w0 = (1, 1, 1, 1), w1 = (1, -1, 1, -1), w2 = (1, 1, -1, -1), w3 = (1, -1, -1, 1), In another embodiment, w0 = (1, 1, 1, 1), w1 = (1, j, -1, -j), w2 = (1, -1, 1, -1), and w3 = (1, -j, -1, j).

[0357] The reference signal is generated by mapping the elements numbered 4p+delta in the sequence {f(t)} to the subcarriers numbered u+L*p+delta, where p=0,…,K-1. delta It can represent different OCC values ​​when delta is different.

[0358] Optionally, generating a reference signal for the first signal includes:

[0359] Performing discrete Fourier transform on the elements of the sequence {x(t)} to obtain a sequence {f(t)}, t=0,…,K-1, where x(t) represents the first sequence;

[0360] The reference signal is generated by mapping the elements numbered p in the sequence {f(t)} to the subcarriers numbered u+L*p+delta, where p=0, ..., K-1.

[0361] Specifically, the terminal and network device can pre-agreed on sequence combinations corresponding to different modulation schemes. For example, 30 sequences can be selected from multiple sequences for 16PSK modulation. These 30 sequences can generate high-performance reference signals. The terminal then selects the first sequence from this sequence combination to generate the reference signal, thereby improving communication efficiency between the terminal and the network device. Correspondingly, the terminal or network device can also select 30 sequences from multiple sequences for 8PSK modulation, or 30 sequences from multiple sequences for 32PSK modulation. The principle behind xn derived from the two formulas above can be further explained. Thus, for a comb-2 structure, the terminal can determine the first sequence used to generate the reference signal transmitted on comb tooth 1 in the comb-2 structure based on preset conditions and the sequence {s(n)}.

[0362] Optionally, when delta=0, the method further includes:

[0363] According to the preset condition and the sequence {s(n)}, the first sequence {x(n)} is determined, and the preset condition is: n =y (n+M)modK , Where, M∈{0,1,2,...,5}, K=6, A is a non-zero complex number,

[0428] The first sequence is determined according to a preset condition and a sequence {s(n)}, wherein the preset condition is: n =y (n+M)modK , Where, M∈{0,1,2,...,5}, K=6, A is a non-zero complex number,

[0433] Specifically, for the comb-2 structure, the terminal can determine, based on preset conditions and sequence {s(n)}, a first sequence for generating a reference signal transmitted on comb tooth 2 in the comb-2 structure. {s(n)} can be selected from a sequence combination (hereinafter referred to as "sequence set 4"), which can be 100 sequences of 8PSK modulation, 100 sequences of 16PSK modulation, or 100 sequences of 32PSK modulation.

[0434] In addition, for the comb-2 structure, the terminal can determine the first sequence used to generate the reference signal transmitted on comb tooth 2 in the comb-2 structure based on the preset conditions and the sequence {s(n)}. Here, {s(n)} can be determined from a sequence combination (hereinafter referred to as "sequence set 4"), and the sequence set 4 can be a portion of multiple sequences of 8PSK modulation, a portion of multiple sequences of 16PSK modulation, or a portion of sequences of 32PSK modulation.

[0435] Hereinafter, unless otherwise specified, the first sequence, or the sequence {x(n)}, or the sequence {x n}, can all be obtained by transforming based on the sequence set AP and the first sequence set to the eighth sequence set as the base sequence.

[0436] It should be noted that the sequences included in sequence combination 3 may be partially or completely identical to the sequences in sequence combination 4, and this application does not limit this.

[0437] Optionally, A may be a modulation symbol, which may be carried on K elements included in the sequence, and A does not change with a change in n.

[0438] Optionally, A is a constant. For example, A=1. For example, A can be a symbol known to both the terminal device and the network device. A can also represent an amplitude.

[0439] It should be noted that the fact that A is a constant within a transmission time unit does not mean that A is fixed. A can vary when the first signal is transmitted at different times. For example, if all N elements in the sequence {x(n)} are reference signals, and A is the amplitude of the reference signal, the terminal device can transmit the signal with A = 1 for the first time. The terminal device can transmit the signal with A = 2 for the second time.

[0440] Optionally, the first sequence may generate the reference signal by repeating the first sequence and performing DFT transformation to generate the reference signal.

[0441] Specifically, for the comb-2 structure, the terminal may repeat the first sequence by performing a [+1+1] repetition or a [+1-1] repetition. After performing a [+1+1] repetition and a DFT transform on the first sequence, the odd-numbered sequences (which can be expressed as 2p+delta, where p=0,…,L-1) among the 2K sequences may be mapped to comb tooth 1 of the comb-2 to generate a reference signal. After performing a [+1-1] repetition and a DFT transform on the first sequence, the even-numbered sequences among the 2K sequences may be mapped to comb tooth 2 of the comb-2 to generate a reference signal.

[0442] In the following embodiments, Φ(0), ..., Φ(5) are used to represent each element in {x(n)}.

[0443] In another embodiment, for the comb-2 structure, the terminal may repeat the first sequence by repeating {Φ(0),...,Φ(5),Φ(0),...,Φ(5)} or by repeating {Φ(0),...,Φ(5),-Φ(0),...,-Φ(5)}. After repeating {Φ(0),...,Φ(5),Φ(0),...,Φ(5)} and performing DFT transformation on the first sequence, the sequence containing 12 elements may be mapped to comb tooth 1 of comb-2 to obtain a frequency domain reference signal on the even subcarriers; after repeating {Φ(0),...,Φ(5),-Φ(0),...,-Φ(5)} and performing DFT transformation on the first sequence, the sequence containing 12 elements may be mapped to comb tooth 2 of comb-2 to obtain a frequency domain reference signal on the odd subcarriers. Afterwards

[0444] For the comb-4 structure, the terminal may repeat the first sequence by [+1+1+1+1], [+1-1+1-1], [+1+1-1-1], or [+1-1+1-1]. After performing [+1+1+1+1] repetition and DFT transformation on the first sequence, the sequence numbered 4p+delta (delta=0) in the 4K sequence may be mapped to Figure 5 The reference signal is generated on the comb tooth 1 shown in FIG. After the first sequence is repeated [+1-1+1-1] and DFT transformed, the sequence numbered 4p+delta (delta=1) in the 4K sequence can be mapped to Figure 5 The reference signal is generated on the comb teeth 2 shown in FIG. After the first sequence is repeated [+1-1+1-1] and DFT transformed, the sequence numbered 4p+delta (delta=2) in the 4K sequence can be mapped to Figure 5The reference signal is generated on the comb teeth 3 shown in FIG. After the first sequence is repeated [+1-1+1-1] and DFT transformed, the sequence numbered 4p+delta (delta=3) in the 4K sequence can be mapped to Figure 5 The reference signal is generated on the comb teeth 4 shown.

[0445] In another embodiment, for the comb-4 structure, the terminal may repeat the first sequence by repeating {Φ(0),...,Φ(5),Φ(0),...,Φ(5),Φ(0),...,Φ(5),Φ(0),...,Φ(5)}, repeating {Φ(0),...,Φ(5),j×Φ(0),...,j×Φ(5),-Φ(0),...,-Φ(5),-j×Φ(0),...,-j×Φ(5)}, repeating {Φ(0),...,Φ(5),-Φ(0),...,-Φ(5),Φ(0),...,Φ(5),-Φ(0),...,-Φ(5)}, or repeating {Φ(0),...,Φ(5),-j×Φ(0),...,-j×Φ(5),-Φ(0),...,-Φ(5),j×Φ(0),...,j×Φ(5)}. After the first sequence is repeated {Φ(0),...,Φ(5),Φ(0),...,Φ(5),Φ(0),...,Φ(5),Φ(0),...,Φ(5)} and DFT transformed, the sequence numbered 4p+delta (delta=0) in the 4K sequence can be mapped to Figure 5 The reference signal is generated on the comb teeth 1 shown in FIG. After the first sequence {Φ(0), ..., Φ(5), j×Φ(0), ..., j×Φ(5), -Φ(0), ..., -Φ(5), -j×Φ(0), ..., -j×Φ(5)} is repeated and DFT transformed, the sequence numbered 4p+delta (delta=1) in the 4K sequence can be mapped to Figure 5 The reference signal is generated on the comb 2 shown in FIG. After the first sequence {Φ(0), ..., Φ(5), -Φ(0), ..., -Φ(5), Φ(0), ..., Φ(5), -Φ(0), ..., -Φ(5)} is repeated and DFT transformed, the sequence numbered 4p+delta (delta=2) in the 4K sequence can be mapped to Figure 5The reference signal is generated on the comb teeth 3 shown in FIG. After the first sequence {Φ(0),...,Φ(5),-j×Φ(0),...,-j×Φ(5),-Φ(0),...,-Φ(5),j×Φ(0),...,j×Φ(5)} is repeated and DFT transformed, the sequence numbered 4p+delta (delta=3) in the 4K sequence can be mapped to Figure 5 The reference signal is generated on the comb teeth 4 shown.

[0446] It should be noted that when K=6, that is, the first sequence is a sequence of 6 lengths, and the first frequency domain resource includes 6 subcarriers, the comb-4 structure needs to occupy 4K=24 subcarriers (i.e., 2 RBs) to meet the selection of 6 subcarriers that meet the requirements from the comb-4 structure; the comb2 structure needs to occupy 2K=12 subcarriers (i.e., 2 RBs) to meet the selection of subcarriers that meet the requirements from the comb-2 structure.

[0447] Optionally, when L=2, K=6, n=0, 1, 2, 3, 4, 5, and delta=0, the reference signal for generating the first signal includes: performing a discrete Fourier transform on the elements in the sequence {z(t)} to obtain a sequence {f(t)}, t=0,…, 2K-1, wherein the sequence {z(a)}=the sequence {x(n)}, a=0,…K-1, the sequence {z(b)}=the sequence {x(n)}, b=K,…2K-1, and x(n) represents the first sequence; and mapping the elements numbered 2p+delta in the sequence {f(t)} to K subcarriers numbered k to generate the reference signal, and p=0,…, L-1.

[0448] Specifically, the sequence {z(t)} can be obtained by repeating the first sequence {x(n)} by [+1+1], that is, when t=a, {z(a)}=the sequence {x(n)}, a=0,…K-1, and when t=b, the sequence {z(b)}=the sequence {x(n)}, b=K,…2K-1. The terminal then obtains the sequence {f(t)} by performing a discrete Fourier transform (DFT) (discrete Fourier transform, DFT) on the elements in the sequence {z(t)}, and maps the k elements numbered 2p+delta (delta=0) in the sequence {f(t)} to the K subcarriers on the first frequency domain resource to generate a reference signal. The embodiment of the present application can convert the time domain sequence {z(t)} into a frequency domain sequence and map it to the corresponding subcarrier.

[0449] For example, the K elements in the sequence {f(t)} are mapped to K equally spaced subcarriers. Figure 6As shown, the interval between the N subcarriers is 1, and the K subcarriers are evenly spaced in the frequency domain. The interval between the subcarriers mapped by elements f(0) to f(K-1) in the sequence {f(t)} is 1 subcarrier. Specifically, they are mapped to K equally spaced subcarriers, and the subcarriers are numbered s+0, s+2, ..., s+2(K-1), where s represents the index of the first subcarrier among the K subcarriers mapped by the sequence {f(t)} in the subcarriers in the communication system.

[0450] Optionally, when L=2, K=6, n=0, 1, 2, 3, 4, 5, and delta=1, generating the reference signal for the first signal includes: performing a discrete Fourier transform on the elements in the sequence {z(t)} to obtain a sequence {f(t)}, t=0, …, 2K-1, where the sequence {z(a)}=the sequence {-1·x(n)}, a=0, …K-1, and the sequence {z(b)}=the sequence {x(n)}, b=K, …2K-1, and x(n) represents the first sequence; and mapping the elements numbered 2p+delta in the sequence {f(t)} to K subcarriers numbered k to generate the reference signal, where p=0, …, L-1.

[0460] Optionally, step 403 may specifically be filtering the first sequence, performing DFT transformation, and mapping the first sequence to the first frequency domain resource to obtain the reference signal. Figure 7 As shown, the first sequence {x(n)} is filtered and DFT is performed to obtain {f(t)}.

[0461] Optionally, step 403 may specifically be to perform DFT transformation on the first sequence, filter it, and then map it to the first frequency domain resource to obtain the reference signal. Figure 8 As shown, after performing DFT transformation on the first sequence {x(n)}, filtering is performed to obtain {f(t)}.

[0462] Optionally, the terminal device performs a sequence {x n} is processed by DFT to obtain the sequence {f n}. This mainly refers to the sequence of terminal equipment configuration {x n} is processed by DFT to obtain the frequency domain sequence, where the frequency domain sequence refers to the sequence {f n}. Then, the terminal device will send the sequence {f n} is mapped to N subcarriers, a first signal is generated and sent to the network device.

[0463] Optionally, the terminal device can be used to generate a sequence of N elements {x n The specific process of performing DFT processing to obtain a frequency domain sequence, then mapping the frequency domain sequence to N subcarriers, generating a first signal, and sending it to the network device includes:

[0464] The terminal device pair contains a sequence of N elements {x n}DFT processing is performed to obtain the sequence {f n}.

[0465] In conjunction with the above description or as a separate embodiment, see Figure 18 After S301 is executed, the terminal device performs DFT processing on the sequence to obtain the sequence {f n}, the filter may not be used. Optionally, the terminal device performs the sequence {x n}DFT processing is performed to obtain the sequence {f n}, DFT processing can be performed after using the filter. Optionally, the terminal device performs DFT processing on the sequence {x n}DFT processing is performed to obtain the sequence {f n In the process of}, the sequence can be obtained by using a filter after DFT processing.

[0466] S302: The terminal device maps the sequence to N subcarriers respectively to obtain N-point frequency domain signals.

[0467] In a specific implementation, the frequency domain signal of N points is a frequency domain signal containing N elements.

[0468] In the following examples of the present application, s represents the sequence {f n}The index of the first subcarrier among the mapped N subcarriers in the communication system.

[0469] Optionally, the terminal device sends the sequence {f n} are mapped to N consecutive subcarriers. n} elements f0 to f N-1 They are mapped to N consecutive subcarriers, and the subcarriers are numbered s+0, s+1, …, s+N-1.

[0470] In one possible example, the terminal device sends the sequence {f n} are mapped to N subcarriers in descending order. n} is mapped to a frequency domain subcarrier. A frequency domain subcarrier is the smallest unit of frequency domain resources and is used to carry data information.

[0471] In one possible example, the terminal device sends the sequence {f n} are mapped to N subcarriers in descending order. n Mapping an element in the datagram to a subcarrier means that the element is carried on that subcarrier. After mapping, when the terminal device transmits data via radio frequency, it is equivalent to sending the element on that subcarrier. In a communication system, different terminal devices can occupy different subcarriers to transmit data. The positions of the N subcarriers within the multiple subcarriers in the communication system can be predefined or configured by network devices through signaling.

[0472] Optionally, the N elements in the sequence may be mapped to N equally spaced subcarriers. Optionally, the interval between the N subcarriers is 1, and the N subcarriers are equally spaced in the frequency domain. n} elements f0 to f N-1 The interval of the mapped subcarriers is 1 subcarrier. Specifically, they are mapped to N equally spaced subcarriers, and the subcarrier numbers are s+0, s+2, ..., s+2(N-1).

[0473] In the embodiment of the present application, the sequence {f n The manner in which the N elements in} are respectively mapped to N subcarriers is not limited to the above manner.

[0474] S303: The terminal device performs an inverse fast Fourier transform (IFFT) on the frequency domain signal containing N elements to obtain a corresponding time domain signal, and adds a cyclic prefix to the time domain signal to generate a first signal.

[0475] S304: The terminal device sends the first signal via radio frequency.

[0476] Optionally, when executing S303, the terminal device generates an N-point frequency domain signal through IFFT to obtain a time domain signal that is an orthogonal frequency division multiplexing (OFDM) symbol. When executing S303, the terminal device sends the first signal through radio frequency. That is, the terminal device sends the bearer sequence {f n} first signal.

[0477] Optionally, the terminal device may send a bearer sequence {f n The first signal of} can also be sent on multiple OFDM symbols to carry the sequence {f n} first signal.

[0478] It should be noted that, in the embodiment of the present application, the method for generating the first signal is not limited to the implementation method in which the above-mentioned terminal device performs DFT processing on the sequence {x(n)} containing N elements to obtain a frequency domain sequence, and then maps the frequency domain sequence to N subcarriers respectively to generate the first signal and send it to the network device.

[0479] Optionally, the sequence {x(n)} can be subjected to a shaping filter to obtain the sequence {y n}, then, the sequence {y n} is modulated onto a carrier to generate a first signal and sent to a network device.

[0480] It should be understood that after performing DFT transformation on the first sequence in step 403, filtering may not be performed, and the reference signal may be directly mapped to the first frequency domain resource. Figure 9 As shown, after performing DFT transformation on the first sequence {x(n)}, {f(t)} is obtained.

[0481] It should be noted that mapping an element in a sequence to a subcarrier can be understood as carrying the element on the subcarrier. After mapping, the terminal can send it via radio frequency.

[0482] 404. The network device generates a local sequence. The local sequence may be the first sequence or the conjugate transpose of the first sequence.

[0483] Specifically, the network device may also pre-store a mapping relationship between the first sequence and the frequency domain resources, or specify the mapping relationship in the protocol, so that the network device can generate first sequences corresponding to different frequency domain resources. Alternatively, when the network device determines that the reference signal is only received on a portion of the frequency domain resources in the comb structure, the network device may only generate the first sequence corresponding to the portion of the frequency domain resources.

[0484] For example, after joining the network, the terminal may use the configured sequence {x(n)} to send PUSCH or DMRS, and the network device may use the sequence {x(n)} configured for the terminal device to receive PUSCH or DMRS.

[0485] 405. The terminal sends the reference signal on the first frequency domain resource. Correspondingly, the network device receives the reference signal on the first frequency domain resource.

[0486] Specifically, in the frequency domain resources of the comb-tooth structure, the reference signals mapped to the frequency domain resources of different comb teeth can be generated using different sequences. In other words, the reference signals on different frequency domain resources can be generated using different sequences as needed, thereby improving the performance of the reference signals transmitted on the frequency domain resources of the comb-tooth structure as a whole. For example, this performance can be at least one of a low peak-to-average power ratio (PAPR), low correlation, good frequency domain flatness, and good time domain autocorrelation.

[0487] It should be noted that the terminal can also send a first signal on the first frequency domain resource. The first frequency domain resource can be the same as the frequency domain resource for sending the reference signal, but the time domain resource is different. This application does not limit this.

[0488] 406. The network device processes the first signal according to the local sequence.

[0489] Specifically, the terminal device determines a corresponding local sequence based on the first frequency domain resource for receiving the reference signal, determines channel quality information based on the local sequence and the reference signal, and then processes the first signal based on the channel quality information. When the local sequence is the first sequence, the network device may determine the channel quality information based on the ratio of the reference signal to the first sequence; when the local sequence is the conjugate of the first sequence, the network device may determine the channel quality information based on the product of the reference signal and the conjugate of the first sequence.

[0490] Another embodiment of the present invention will be described below. This embodiment relates to a sequence-based signal processing method, comprising:

[0537] A generating unit for generating a sequence {x n} Generate a first signal;

[0538] A sending unit, configured to send the first signal.

[0539] As an embodiment, the sequence {s n The set of} includes at least one of the sequences in the second sequence set, and the second sequence set includes part of the sequences in the first sequence set.

[0540] As an embodiment, the device further includes:

[0541] The generating unit is further configured to generate the sequence {x n} perform discrete Fourier transform on the N elements in the sequence {f n};

[0542] The generating unit is further configured to convert the sequence {f n The N elements in} are respectively mapped to N subcarriers to obtain a frequency domain signal including N elements;

[0543] The generating unit is further configured to generate the first signal according to the frequency domain signal.

[0544] As an embodiment, the N subcarriers are N consecutive subcarriers, or N equally spaced subcarriers.

[0545] As an embodiment, the signal processing device further includes a filtering unit for filtering the sequence {x n Before performing discrete Fourier transform on the N elements in the sequence {x n} for filtering; or

[0546] The filtering unit is used to filter the sequence {x n After performing discrete Fourier transform on the N elements in the sequence {x n} for filtering.

[0547] As an embodiment, the first signal is a reference signal of the second signal, and the modulation mode of the second signal is π / 2 binary phase shift keying BPSK.

[0548] The above process supports multiple frequency-division orthogonal DMRS ports. For example, in combo-2, two orthogonal DMRS ports occupy different subcarriers, and in combo-4, four orthogonal DMRS ports occupy different subcarriers. To support more users, it is necessary to support more orthogonal DMRS ports on the same frequency domain resources through code division multiplexing.

[0549] Specifically, the sequence used by DMRS port 0 is expressed as {Φ(0), ..., Φ(5), Φ(0), ..., Φ(5)}, and the sequence used by DMRS port 0 will undergo DFT transformation, and optionally perform IDFT transformation after filtering operation to form DMRS port 0. The DMRS port 0 occupies frequency domain comb tooth 1, then the orthogonal method 1 is: DMRS port 2 occupying frequency domain comb tooth 2 can adopt {Φ(0), ..., Φ(5), -Φ(0), ..., -Φ(5)} sequence, which will undergo DFT transformation, and optionally perform IDFT transformation after filtering operation to form DMRS port 2;

[0550] Orthogonal method 2 is: DMRS port 2 occupying frequency domain comb tooth 2 can also use the {Φ(0),...,Φ(5)} sequence, which will be transformed by DFT and then perform a tensor product operation (Kronnecker) with the vector [0 1] to form a 12-long sequence. For example, {β(0),...,β(5)} is the sequence of {Φ(0),...,Φ(5)} after DFT transformation, then the Kronnecker operation is Optionally, an IDFT transform is performed after the filtering operation to form DMRS port 2;

[0551] Orthogonal mode 3: DMRS port 2 occupying frequency domain comb tooth 2 can adopt [Φ(0),...,Φ(5),Φ(0),...,Φ(5)]·[e π×j×0 / 6 e π×j×1 / 6 ... e π×j×11 / 6 ] sequence, which is subjected to DFT transformation, optional filtering operation, and then IDFT transformation to form DMRS port 2. The above-mentioned orthogonal methods one, two, and three are used to form orthogonal DMRS ports occupying different subcarriers.

[0552] Orthogonal mode four is: performing a cyclic shift (CS) operation on the sequence used by DMRS port 0. One cyclic shift mode is to shift the sequence length to the left by 1 / 4 to form the sequence of DMRS port 1. For example, DMRS port 1 is {Φ(3),Φ(4),Φ(5),Φ(0),...,Φ(5),Φ(0),Φ(1),Φ(2)}. The sequence used by DMRS port 1 will undergo DFT transformation, and optionally perform IDFT transformation after filtering operation to form DMRS port 1. DMRS port 1 occupies frequency domain comb tooth 1.

[0553] Orthogonal method five is: perform a point multiplication operation on DMRS port 0 and the Walsh code to form a sequence of DMRS port 1, wherein the Walsh code can be: [1 -1 1 -1 1 -1 1 -1 1 -1 1 -1], or [1 1 1 -1 -1 -1 1 1 -1-1 -1], or [e 2×π×j×0 / 6 e 2×π×j×1 / 6 ... e 2×π×j×11 / 6 For example, if the Walsh code [1 -1 1 -1 1 -1 1 -1 1 -1 -1] is used, the DMRS port 1 is {Φ(0),Φ(1),Φ(2),-Φ(3),-Φ(4),-Φ(5),Φ(0),Φ(1),Φ(2),-Φ(3),-Φ(4),-Φ(5)}

[0554] , the sequence used by the DMRS port 1 will undergo DFT transformation, and optionally perform IDFT transformation after filtering operation to form DMRS port 1, and the DMRS port 1 occupies frequency domain comb tooth 1;

[0555] The third sequence set adopts orthogonal mode 1 to form DMRS port 2, and adopts orthogonal mode 4 to form DMRS port 1 and DMRS port 3 based on DMRS port 0 and DMRS port 2 respectively;

[0556] The fourth sequence set and the fifth sequence set adopt orthogonal mode 1 to form DMRS port 2, and adopt orthogonal mode 5 to form DMRS port 1 and DMRS port 3 based on DMRS port 0 and DMRS port 2 respectively;

[0557] The sixth sequence set adopts orthogonal mode 2 to form DMRS port 2, and adopts orthogonal mode 4 to form DMRS port 1 and DMRS port 3 based on DMRS port 0 and DMRS port 2 respectively;

[0558] The seventh sequence set adopts orthogonal mode 3 to form DMRS port 2, and adopts orthogonal mode 4 to form DMRS port 1 and DMRS port 3 based on DMRS port 0 and DMRS port 2 respectively;

[0559] The eighth sequence set adopts orthogonal mode 1 to form DMRS port 2, and adopts orthogonal mode 5 to form DMRS port 1 and DMRS port 3 based on DMRS port 0 and DMRS port 2 respectively.
