PSK (Phase Shift Keying) and multiphase phase shift keying (mPSK, multiple phase Shift Keying). mQAM and Binary Phase Shift Keying (BPSK) are widely used in modern communications, such as Long Term Evolution (LTE) communication and Wideband Code Division Multiple Access (WCDMA) communication.

下面结合附图对本发明实施例进行说明。The embodiments of the present invention will be described below with reference to the accompanying drawings.

实施例1Example 1

本实施例提供了一种数字调制方法，该方法应用于发送端，可以应用于网络设备也可以应用于用户设备，图4是该方法的示意图，如图4所示，该方法包括：The present embodiment provides a digital modulation method, which is applied to a transmitting end, and can be applied to a network device or a user equipment. FIG. 4 is a schematic diagram of the method. As shown in FIG. 4, the method includes:

步骤401：将包含第一信息的待调制信息映射为具有第一幅度的符号，将包含第二信息的待调制信息映射为具有第二幅度的符号，第一信息的出现概率小于第二信息的出现概率，第一信息的出现概率与第二信息的出现概率之和为1，第一幅度大于第二幅度。Step 401: Map the information to be modulated including the first information into a symbol having a first amplitude, and map the information to be modulated including the second information into a symbol having a second amplitude, where the probability of occurrence of the first information is smaller than that of the second information. The probability of occurrence, the sum of the probability of occurrence of the first information and the probability of occurrence of the second information is 1, and the first magnitude is greater than the second magnitude.

在本实施例中，将待调制信息映射为一个符号，该符号称为调制符号，在本实施例中，该待调制信息可以包含第一信息，也可以包含第二信息，或者同时包含第一信息和第二信息。如果该待调制信息包含第一信息，则可以将该第一信息映射为具有第一幅度的符号，如果该待调制信息包含第二信息，则可以将该第二信息映射为具有第二幅度的符号。并且，在本实施例中，与第一信息和第二信息等概率出现的假设或情况不同，该第一信息的出现概率与该第二信息的出现概率之和为1，并且，该第一信息的出现概率小于该第二信息的出现概率，而上述第一幅度大于上述第二幅度。In this embodiment, the information to be modulated is mapped to a symbol, and the symbol is referred to as a modulation symbol. In this embodiment, the information to be modulated may include the first information, or may include the second information, or include the first Information and second information. If the to-be-modulated information includes the first information, the first information may be mapped to have the first A symbol of amplitude, if the information to be modulated contains the second information, the second information may be mapped to a symbol having the second amplitude. In addition, in this embodiment, the difference between the probability of occurrence of the first information and the probability of occurrence of the second information is different, and the sum of the probability of occurrence of the first information and the probability of occurrence of the second information is 1, and the first The probability of occurrence of the information is less than the probability of occurrence of the second information, and the first amplitude is greater than the second amplitude.

也就是说，在本实施例中，对出现概率较低的信息(例如第一信息)分配一个幅度较大(例如第一幅度)的星座点(符号)，而出现概率较高的信息(例如第二信息)分配一个幅度较低(例如第二幅度)的星座点，由此保证了第一信息和第二信息出现概率不同时的调制性能，并且，在第一信息和第二信息的出现概率明显不同时，相比于现有的调制方法，调制性能可以显著提升。That is to say, in the present embodiment, information having a relatively low probability of occurrence (for example, first information) is assigned a constellation point (symbol) having a large amplitude (for example, a first amplitude), and information having a high probability of occurrence (for example, The second information) allocates a constellation point having a lower amplitude (for example, the second amplitude), thereby ensuring modulation performance when the first information and the second information have different probability of occurrence, and, in the presence of the first information and the second information When the probabilities are significantly different, the modulation performance can be significantly improved compared to the existing modulation methods.

在本实施例中，以待调制信息包含前述两类信息为例，但本实施例并不以此作为限制，待调制信息中包含的每类信息可以分别包含一种或多种信息，本实施例的方法适用于这两类信息的出现概率不同的情况。并且，在本实施例中，“类”的概念只是为了区分出现概率不同的信息，并不意味着这两类信息在功能、类别等上的不同。In this embodiment, the information to be modulated includes the foregoing two types of information as an example, but the embodiment does not limit the information, and each type of information included in the information to be modulated may separately include one or more types of information. The method of the example applies to the case where the probability of occurrence of these two types of information is different. Moreover, in the present embodiment, the concept of "class" is only for distinguishing information having different occurrence probabilities, and does not mean that the two types of information differ in function, category, and the like.

在一个实施方式中，该待调制信息为1比特的信息，也就是说，该待调制信息只有两种可能，“0”或者“1”，则该“0”和“1”可以分别表示上述第二信息和上述第一信息，则该第一信息(也即“1”)可以被映射为幅度为x₁的符号，而该第二信息(也即“0”)可以被映射为幅度为x₂的符号，x₁＞x₂。在本实施例中，x₂可以是预先定义的值，例如为0或者为0.5等，x₁可以是根据x₂以及前述第一信息的出现概率和前述第二信息的出现概率而确定的值，例如，x₁可以根据以下公式确定：In one embodiment, the information to be modulated is 1-bit information, that is, the information to be modulated has only two possibilities, “0” or “1”, and the “0” and “1” may respectively represent the above. The second information and the first information, the first information (ie, "1") may be mapped to a symbol of magnitude x ₁ , and the second information (ie, "0") may be mapped to an amplitude of The sign of x ₂ , x ₁ >x ₂ . In this embodiment, x ₂ may be a predefined value, for example, 0 or 0.5, etc., and x ₁ may be a value determined according to x ₂ and an occurrence probability of the foregoing first information and an occurrence probability of the foregoing second information. For example, x ₁ can be determined according to the following formula:

x₁ ²×P(1)+x₂ ²×P(0)＝1； _{^{x 1 2 × P (1)}} + x 2 2 × P (0) = 1;

P(1)+P(0)＝1；P(1)+P(0)=1;

其中，P(0)为第二信息(也即“0”)的出现概率，P(1)为第一信息(也即“1”)的出现概率，P(1)＜P(0)，由此，当x₂预设为0时，

当x₂预设为其他值时，x₁可以根据前述公式确定。Where P(0) is the probability of occurrence of the second information (ie, “0”), and P(1) is the probability of occurrence of the first information (ie, “1”), P(1)<P(0), Thus, when x _{2 is} preset to 0,

When x _{2 is} preset to other values, x ₁ can be determined according to the aforementioned formula.

本实施方式可以称为基于“0”和“1”的出现概率的BPSK方式，在本实施方式中，为出现概率较低的比特1分配了一个幅度较大的星座点，并且为出现概率较高的比特0分配了一个幅度较低的星座点。图5是本实施方式的一个示例的星座图，在图5的示例中，该BPSK符号(星座点)为：[x₂x₁]，由于比特0出现概率较大，可以映射为符号0(幅度为零)，也即x₂＝0，比特1出现概率较小，可以映射为符号x，也即

This embodiment may be referred to as a BPSK method based on the occurrence probability of “0” and “1”. In the present embodiment, a constellation point having a larger amplitude is allocated to the bit 1 having a lower probability of occurrence, and the probability of occurrence is higher. The high bit 0 is assigned a lower constellation point. FIG. 5 is a constellation diagram of an example of the present embodiment. In the example of FIG. 5, the BPSK symbol (constellation point) is: [x ₂ x ₁ ], and since bit 0 has a high probability of occurrence, it can be mapped to symbol 0 ( The amplitude is zero), ie x ₂ =0, the probability of occurrence of bit 1 is small and can be mapped to the symbol x, ie

在另一个实施方式中，该待调制信息为2比特的信息，也就是说，该待调制信息有四种可能，“00”、“01”、“10”以及“11”。如果仍以“0”表示上述第二信息，“1”表示上述第一信息，则该调制信息可以为仅包含第一信息(对应“11”)，也可以为仅包含第二信息(对应“00”)，还可以为既包含第一信息又包含第二信息(对应“01”或“10”)，则在本实施方式中，该两个比特的待调制信息可以分别映射为实数和虚数，也即一个星座点的实部和虚部，其中，出现概率较低的比特“1”被分配一个幅度较大的星座点，出现概率较高的比特“0”被分配一个幅度较小的星座点。In another embodiment, the information to be modulated is 2-bit information, that is, the information to be modulated has four possibilities, "00", "01", "10", and "11". If the second information is still indicated by "0", and "1" indicates the first information, the modulation information may include only the first information (corresponding to "11"), or may only include the second information (corresponding to " 00′), may also include both the first information and the second information (corresponding to “01” or “10”), in this embodiment, the two bits of the to-be-modulated information may be mapped to real and imaginary numbers, respectively. , that is, the real part and the imaginary part of a constellation point, wherein the bit "1" with a lower probability of occurrence is assigned a larger constellation point, and the bit "0" with a higher probability of occurrence is assigned a smaller amplitude. Constellation point.

本实施方式可以称为基于“0”和“1”的出现概率的QPSK方式，图6是本实施方式的一个示例的星座图，在图6的示例中，该QPSK符号(星座点)为：[x₂+x₂×j x₁+x₂×j x₁+x₁×j x₂+x₁×j]，x₁和x₂由以下公式确定：This embodiment may be referred to as a QPSK method based on the appearance probability of "0" and "1", and FIG. 6 is a constellation diagram of an example of the present embodiment. In the example of FIG. 6, the QPSK symbol (constellation point) is: [x ₂ + x ₂ × j x ₁ + x ₂ × j x ₁ + x ₁ × j x ₂ + x ₁ × j], x ₁ and x ₂ are determined by the following formula:

x₁ ²×P(1)+x₂ ²×P(0)＝0.5；x ₁ ² ×P(1)+x ₂ ² ×P(0)=0.5;

P(1)+P(0)＝1；P(1)+P(0)=1;

仍以x₂＝0，x₁＝x为例，则该QPSK符号(星座点)为：[0x x+x×j x×j]，分别对应[00，10，11，01]，

并且

Still taking x ₂ =0, x ₁ = x as an example, the QPSK symbol (constellation point) is: [0x x+x×j x×j], corresponding to [00,10,11,01],

and

以上以待调制信息为1比特的信息和2比特的信息为例，对本实施例的数字调制方法做了说明，本实施例并不以此作为限制，对于待调制信息为4比特的信息或其他比特的信息的情况，调制方式与上述两个实施方式类似，此处不再重复说明。The digital modulation method of the present embodiment is described by taking the information to be modulated as 1 bit and the information of 2 bits as an example. The present embodiment is not limited thereto, and the information to be modulated is 4 bits or other information. In the case of bit information, the modulation method is similar to the above two embodiments, and the description thereof will not be repeated here.

以上两个实施方式以“0”的出现概率大于“1”的出现概率为例，但本实施例并不以此作为限制，在具体实施时，也可以用“0”表示第一信息，用“1”表示第二信息，则P(0)＜P(1)，P(1)+P(0)＝1，x₂＞x₁。The above two embodiments are exemplified by the probability that the probability of occurrence of "0" is greater than the probability of occurrence of "1", but this embodiment is not limited thereto. In the specific implementation, the first information may also be represented by "0". "1" indicates the second information, then P(0) < P(1), P(1) + P(0) = 1, x ₂ > x ₁ .

在本实施例中，上述待调制信息可以是混合自动重传请求(HARQ，Hybrid Automatic Repeat reQuest)确认字符(数据检测传输成功(ACK，ACKnowledgement)或失败(NACK，Negative ACKnowledgment)，简称为ACK/NACK)，上述第一信息可以是数据检测失败(NACK)信息，上述第二信息可以是数据检测成功(ACK)信息。In this embodiment, the to-be-modulated information may be a Hybrid Automatic Repeat reQuest (HARQ) acknowledgement character (ACK, ACKnowledgement, or NACK (Negative ACKnowledgment), referred to as ACK/ NACK), the first information may be data detection failure (NACK) information, and the second information may be data detection success (ACK) information.

也就是说，对于1比特的HARQ ACK/NACK，可以通过“0”表示ACK，通过“1”表示NACK，反之亦然。由此，本实施例的数字调制方法适用于“ACK”的出现概率大于“NACK”的出现概率的场景，例如高可靠低时延业务(URLLC，Ultra-Reliable and Low Latency Communications)场景。That is, for a 1-bit HARQ ACK/NACK, an ACK can be indicated by "0", a NACK by "1", and vice versa. Thus, the digital modulation method of the present embodiment is applicable to the "ACK" A scenario in which the probability of occurrence is greater than the probability of occurrence of "NACK", such as the URL-LLC (Ultra-Reliable and Low Latency Communications) scenario.

下面结合具体的场景对本实施例的数字调制方法进行说明。The digital modulation method of this embodiment will be described below in conjunction with a specific scenario.

HARQ是一种将前向纠错编码(FEC，Forward Error Correction)和自动重传请求(ARQ，Automatic Repeat reQuest)相结合而形成的技术。它广泛用于现代通信***中，常与循环冗余校验(Cyclic Redundancy Check，CRC)一起使用。CRC校验是一种根据网络数据包或电脑文件等数据产生简短固定位数校验码的一种散列函数，主要用来检测或校验数据传输或者保存后可能出现的错误。在发送端发送数据之后，接收端根据接收的数据做CRC校验，根据校验检测结果，接收端会向发送端反馈数据检测成功(ACK)或者失败(NACK)的信息，发送端根据反馈的ACK/NACK信息决定发送新数据或者重新发送旧数据。图7示意了数据检测成功的信息交互过程，图8示意了数据检测失败的信息交互过程。HARQ is a technology that combines Forward Error Correction (FEC) and Automatic Repeat ReQuest (ARQ). It is widely used in modern communication systems and is often used with the Cyclic Redundancy Check (CRC). CRC check is a hash function that generates a short fixed-digit check code based on data such as network packets or computer files. It is mainly used to detect or verify errors that may occur after data transmission or storage. After the data is sent by the transmitting end, the receiving end performs a CRC check according to the received data. According to the check result, the receiving end feeds back the information of the data detection success (ACK) or the failure (NACK) to the transmitting end, and the transmitting end according to the feedback. The ACK/NACK information determines whether new data is to be sent or old data is resent. Figure 7 illustrates the information exchange process for successful data detection, and Figure 8 illustrates the information interaction process for data detection failure.

接收端向发送端反馈ACK/NACK信息的物理信道往往采用低阶调制，例如BPSK或者QPSK，当传送一个比特的ACK/NACK信息时采用BPSK，而传送两个比特的ACK/NACK信息时采用QPSK。在某些特殊应用下，例如高可靠低时延业务中，数据包正确概率往往非常接近100％，例如5G的URLLC场景下，误块率在10^-5数量级，这就意味着NACK发生的概率远远小于ACK发生的概率，此时ACK/NACK信息可以使用本实施例的基于“0”和“1”的出现概率的BPSK或者QPSK数字调制方法进行调制，可以预先设置NACK的出现概率x₂，0≤︱x₂︱＜1。例如，将NACK的出现概率设为10％，则

在实际部署时，可根据需要将参数x₂设置成一个收发双方共同认可的值即可。The physical channel that the receiving end feeds back the ACK/NACK information to the transmitting end often adopts low-order modulation, such as BPSK or QPSK, BPSK is used when transmitting one-bit ACK/NACK information, and QPSK is used when transmitting two-bit ACK/NACK information. . In some special applications, such as high-reliability and low-latency services, the correct probability of data packets is often very close to 100%. For example, in a URLG scenario of 5G, the block error rate is on the order of 10 ^-5 , which means the probability of NACK occurring. It is much smaller than the probability of occurrence of ACK. At this time, the ACK/NACK information can be modulated using the BPSK or QPSK digital modulation method based on the appearance probability of “0” and “1” of the present embodiment, and the probability of occurrence of NACK x ₂ can be set in advance. , 0 ≤ - x _{2 -} <1. For example, if the probability of occurrence of NACK is set to 10%, then

In actual deployment, the parameter x ₂ can be set to a value mutually recognized by both the transmitting and receiving parties as needed.

在LTE协议中，ACK/NACK信息分为针对上行和针对下行两种。前者由物理混合自动重传指示信道(PHICH，Physical Hybrid ARQ Indicator Channel)传输，后者由物理上行链路控制信道(PUCCH，Physical Uplink Control CHannel)传输。下面以本实施例的数字调制方法(基于“0”和“1”的出现概率的BPSK/QPSK)应用在PHICH和PUCCH中为例进行说明，在以下说明中，假设“1”表示NACK，而“0”表示ACK，并且，假设x₂＝0。但本实施例并不以此作为限制，也可以通过“0”表示NACK，而通过“1”表示ACK，只要NACK的出现概率小于ACK的出现概率都适用于本实施例的方法。 In the LTE protocol, ACK/NACK information is classified into uplink and downlink. The former is transmitted by a Physical Hybrid ARQ Indicator Channel (PHICH), which is transmitted by a Physical Uplink Control CHannel (PUCCH). The digital modulation method of the present embodiment (BPSK/QPSK based on the occurrence probability of "0" and "1") is applied to the PHICH and PUCCH as an example. In the following description, it is assumed that "1" represents NACK, and “0” indicates ACK, and it is assumed that x ₂ =0. However, the present embodiment is not limited thereto. The ACK may be represented by “0” and the ACK by “1”, and the probability of occurrence of the NACK is less than the probability of occurrence of the ACK.

对于PHICH信道，在物理层，网络设备可以先对每个HARQ确认信息(1比特：对应一个上行传输块(TB，Transport Block)的ACK/NACK)重复3遍，得到3比特的信息，接着使用本实施例的数字调制方法(基于“0”和“1”的出现概率的BPSK调制方法)对这3比特的信息进行调制，再使用一个长为4(对于扩展的循环前缀而言，长为2)的正交序列进行扩频，然后使用小区特定的搅扰序列进行加扰后，就得到12个加扰符号，如图9所示。多个PHICH映射同一个PHICH group时，可以将多个PHICH映射到同一个资源单元(RE，Resource Element)的符号相加来实现。每个PHICH group可以映射到3个资源单元组(REG，Resource Element Group)中，这3个REG可以是分开的，彼此间隔1/3下行***带宽。本实施例对这12个符号如何映射到对应的REG、层匹配、预编码、以及如何映射到RE不作限制。For the PHICH channel, at the physical layer, the network device may first repeat 3 times for each HARQ acknowledgment information (1 bit: ACK/NACK corresponding to one BC (Transport Block)) to obtain 3 bits of information, and then use The digital modulation method of the present embodiment (the BPSK modulation method based on the appearance probability of "0" and "1") modulates the 3-bit information, and then uses a length of 4 (for the extended cyclic prefix, the length is 2) The orthogonal sequence is spread and then scrambled using the cell-specific interference sequence to obtain 12 scrambling symbols, as shown in FIG. When multiple PHICHs are mapped to the same PHICH group, multiple PHICHs can be mapped to the same resource unit (RE, Resource Element) to add the symbols. Each PHICH group can be mapped into three Resource Element Groups (REGs), which can be separated by 1/3 downlink system bandwidth. This embodiment does not limit how the 12 symbols are mapped to the corresponding REG, layer matching, precoding, and how to map to the RE.

当使用本实施例的数字调制方法对上述3比特的信息进行调制时，可以直接将原有的星座点替换为本实施例的星座点，如图5所示，表1示意了图5所示的星座点的实部和虚部。When the above 3-bit information is modulated by using the digital modulation method of this embodiment, the original constellation point can be directly replaced with the constellation point of the embodiment, as shown in FIG. 5, and Table 1 shows FIG. The real and imaginary parts of the constellation point.

在表2中，b(i)，b(i+1)表示比特，i是比特序号；I和Q分别代表一个星座点(符号)的实部和虚部，在本示例中，x₂＝0，

其含义如前所述，此处不再赘述。In Table 2, b(i), b(i+1) represents a bit, i is a bit number; I and Q represent the real and imaginary parts of a constellation point (symbol), respectively, in this example, x ₂ = 0,

Its meaning is as described above and will not be described here.

对于PUCCH 2a/2b信道，物理层的操作如图11所示。PUCCH format 2a可以携带20比特的信道状态信息(CSI，Channel State Information)(QPSK调制)和1比特的ACK/NACK信息(BPSK调制)(对应单小区、下行单码字的场景)。PUCCH format2b可以携带20比特的CSI信息(QPSK调制)和2比特的ACK/NACK信息(QPSK调制)(对应单小区、下行双码字的场景)。对于1比特或2比特的ACK/NACK信息，可以使用本实施例的方法进行调制，在具体实施时，可以直接将原有的星座点替换为本实施例的星座点，如图5或图6所示，上述表1示意了图5所示的星座点的实部和虚部，上述表2示意了图6所示的星座点的实部和虚部，下面的表3示意了另一种形式的星座点。For the PUCCH 2a/2b channel, the operation of the physical layer is as shown in FIG. The PUCCH format 2a can carry 20-bit Channel State Information (CSI) and 1-bit ACK/NACK information (BPSK modulation) (a scene corresponding to a single cell and a downlink single codeword). The PUCCH format 2b can carry 20-bit CSI information (QPSK modulation) and 2-bit ACK/NACK information (QPSK modulation) (a scenario corresponding to a single cell and a downlink dual codeword). For the ACK/NACK information of 1 bit or 2 bits, the method of the embodiment may be used for modulation. In a specific implementation, the original constellation point may be directly replaced with the constellation point of the embodiment, as shown in FIG. 5 or FIG. 6 . As shown, Table 1 above shows the real and imaginary parts of the constellation points shown in Fig. 5. Table 2 above shows the real and imaginary parts of the constellation points shown in Fig. 6, and Table 3 below shows another The form of the constellation point.

在5G/NR中，具体协议还在制定之中。下面也以“1”表示NACK而“0”表示ACK为例对本实施例的方法应用于5G/NR为例进行说明。In 5G/NR, specific agreements are still being worked out. Hereinafter, an example in which the method of the present embodiment is applied to the 5G/NR will be described by taking "1" for NACK and "0" for ACK as an example.

在5G/NR子帧中，ACK/NACK反馈属于控制信道，在子帧中，上行控制信道时间上在保护时间和上行数据信道之间，如图12所示。In the 5G/NR subframe, the ACK/NACK feedback belongs to the control channel, and in the subframe, the uplink control channel is temporally between the guard time and the uplink data channel, as shown in FIG.

上行ACK/NACK的1比特ACK/NACK反馈信息用本实施例的基于“0”和“1”的出现概率的BPSK的调制方法进行调制，上行ACK/NACK的2比特ACK/NACK反馈信息用本实施例的基于“0”和“1”的出现概率的QPSK的调制方法进行调制，调制后的符号记为符号y(0)，然后对y(0)进行扩频，最后将扩频之后的数据按照一定的规则映射到物理层的时频资源中。具体的数据传输方法将在实施例2中进行说明。 The 1-bit ACK/NACK feedback information of the uplink ACK/NACK is modulated by the BPSK modulation method based on the appearance probability of "0" and "1" in the present embodiment, and the 2-bit ACK/NACK feedback information of the uplink ACK/NACK is used. The modulation method of the QPSK based on the appearance probability of "0" and "1" of the embodiment is modulated, the modulated symbol is denoted by the symbol y(0), then the y(0) is spread, and finally the spread is performed. The data is mapped to the time-frequency resources of the physical layer according to certain rules. A specific data transmission method will be described in Embodiment 2.

以上以待调制信息为HARQ ACK/NACK为例对本实施例的数字调制方法进行了说明，但本实施例并不以此作为限制，本实施例的数字调制方法也适用于其他控制信息。The digital modulation method of the present embodiment has been described above by taking the information to be modulated as HARQ ACK/NACK as an example. However, the present embodiment is not limited thereto, and the digital modulation method of this embodiment is also applicable to other control information.

通过本实施例的方法，可以在“0”和“1”的出现概率不等的情况下保证调制性能。With the method of the present embodiment, the modulation performance can be guaranteed in the case where the occurrence probabilities of "0" and "1" are not equal.

实施例2Example 2

本实施例提供了一种数据传输方法，该方法应用于发送端，可以应用于网络设备也可以应用于用户设备。图13是该方法的示意图，如图13所示，该方法包括：This embodiment provides a data transmission method, which is applied to a transmitting end, and can be applied to a network device or a user equipment. Figure 13 is a schematic diagram of the method, as shown in Figure 13, the method comprising:

步骤1301：对待调制信息进行调制，得到调制符号；Step 1301: Modulate modulation information to obtain a modulation symbol;

步骤1302：发送上述调制符号。Step 1302: Send the above modulation symbol.

在本实施例在步骤1301中，采用实施例1的方法对待调制信息进行调制，由于在实施例1中，已经对该调制方法和该待调制信息进行了详细说明，其内容被合并于此，此处不再赘述。In the embodiment, in step 1301, the modulation information is modulated by the method of Embodiment 1. Since the modulation method and the information to be modulated have been described in detail in Embodiment 1, the content thereof is incorporated herein. I will not repeat them here.

在本实施例的一个实施方式中，对于5G/NR***，在步骤1302中，可以先对上述调制符号进行扩频，得到扩频后的数据，再将扩频后的数据映射到物理层的时频资源中，以进行传输。In an embodiment of the present embodiment, for the 5G/NR system, in step 1302, the modulation symbol may be first spread to obtain the spread data, and then the spread data is mapped to the physical layer. Time-frequency resources for transmission.

在本实施方式中，对调制符号进行扩频可以分为两级，第一级可以将上述调制符号乘以长度为N1的序列，得到长度为N1的第一序列；第二级可以将该第一序列乘以长度为N2的循环移位序列，得到长度为N1×N2的第二序列，该第二序列即为扩频后的数据，并且，该第二序列可以分为N1组，每组的长度为N2。在本实施方式中，上述长度为N1的序列可以是正交码，也可以是非正交码。In this embodiment, the spreading of the modulation symbols may be divided into two levels. The first stage may multiply the modulation symbols by a sequence of length N1 to obtain a first sequence of length N1; the second stage may A sequence is multiplied by a cyclic shift sequence of length N2 to obtain a second sequence of length N1×N2, which is a spread spectrum data, and the second sequence can be divided into N1 groups, each group The length is N2. In the present embodiment, the sequence of length N1 may be an orthogonal code or a non-orthogonal code.

下面举例说明。The following is an example.

在第一级扩频中，可以用长度为N1的序列

0≤m≤N1。其中n_oc为序列索引。当N1＝4时，序列

可以定义为表4所示，但不限于此。 In the first stage of spreading, a sequence of length N1 can be used.

0 ≤ m ≤ N1. Where n _oc is the sequence index. When N1=4, the sequence

It can be defined as shown in Table 4, but is not limited thereto.

表4Table 4

在第二级扩频中，可以用长度为N2的循环移位序列

0≤n_cs≤N2-1，0≤n≤N2-1。其中，u是正交序列索引(u＝0,1,2,3,…)，α是循环移位值。当N2＝12，α＝0时，循环移位序列可以定义为表5所示，但不限于此。In the second-stage spread spectrum, a cyclic shift sequence of length N2 can be used.

0 ≤ n _cs ≤ N2-1, 0 ≤ n ≤ N2-1. Where u is an orthogonal sequence index (u=0, 1, 2, 3, ...), and α is a cyclic shift value. When N2=12, α=0, the cyclic shift sequence can be defined as shown in Table 5, but is not limited thereto.

表5table 5

经过两次扩频后，形成长度为N1×N2的序列

它可以分为N1个组，每个组长度为N2。当N1＝4，N2＝12时，分为四组，每组长度为12，总长度为48。After two spreads, a sequence of length N1×N2 is formed.

It can be divided into N1 groups, each group having a length of N2. When N1=4 and N2=12, they are divided into four groups, each group having a length of 12 and a total length of 48.

在本实施方式中，经过扩频之后，需要将N1×N2个数据映射到物理层上的RE。每个RE有两个索引k和l，分别是频率和时间索引，代表RE所在的OFDM符号的序号和子载波序号。In the present embodiment, after spreading, it is necessary to map N1×N2 data to REs on the physical layer. Each RE has two indexes k and l, which are frequency and time indices, respectively, representing the sequence number and subcarrier number of the OFDM symbol in which the RE is located.

在本实施方式中，可以将所有数据，也即上述第二序列映射到同一个OFDM符号中的不同子载波上，其中，每组第二序列对应的子载波在频域上是连续的，不同组第二序列对应的子载波之间可以是连续的，也可以是不连续的，如图14所示。In this embodiment, all the data, that is, the foregoing second sequence, may be mapped to different subcarriers in the same OFDM symbol, where the subcarriers corresponding to each group of the second sequence are continuous in the frequency domain, different. The subcarriers corresponding to the second sequence of the group may be continuous or discontinuous, as shown in FIG.

在本实施方式中，也可以将不同组的数据，也即上述第二序列映射到不同的OFDM符号且不同的子载波集合上，如图15所示，四个组的第二序列被映射到了四个不同的OFDM符号且不同的子载波上。In this embodiment, different sets of data, that is, the second sequence, may be mapped to different OFDM symbols and different subcarrier sets. As shown in FIG. 15, the second sequence of the four groups is mapped. Four different OFDM symbols and different subcarriers.

在本实施方式中，还可以将不同组的数据，也即上述第二序列映射到不同的OFDM符号且不同的子载波集合上，如图16所示，四个组的第二序列被映射到了四个不同的OFDM且相同的子载波上。In this embodiment, different sets of data, that is, the foregoing second sequence, may also be mapped to different OFDM symbols and different subcarrier sets. As shown in FIG. 16, the second sequence of the four groups is mapped. Four different OFDMs and on the same subcarrier.

在本实施例的一个实施方式中，当上述待调制信息为HARQ ACK/NACK时，如果该HARQ ACK/NACK以PUCCH格式1a或者PUCCH格式1b在PUCCH上发送，则可以在专用资源上发送上述调制符号。这里的专用资源例如为根据第一个CCE计算出的PUCCH1资源。In an embodiment of the present embodiment, when the to-be-modulated information is HARQ ACK/NACK, if the HARQ ACK/NACK is transmitted on the PUCCH in PUCCH format 1a or PUCCH format 1b, the modulation may be sent on a dedicated resource. symbol. The dedicated resource here is, for example, a PUCCH1 resource calculated according to the first CCE.

在LTE中，当用户设备需要同时发送调度请求(SR，Scheduling Request)和HARQ ACK/NACK时，HARQ ACK/NACK会在SR资源上发送，而不是在根据第一个CCE计算出的PUCCH 1资源(这里我们将其称为ACK/NACK资源)上发送。此时，ACK/NACK资源上不发送任何东西，即是没有能量的。网络设备通过比较ACK/NACK资源和SR资源上检测到的能量，就知道用户设备是否发送了SR。根据本实施例的调制方式，当用户设备同时发送SR和HARQ ACK/NACK时，HARQ ACK/NACK不会在SR资源上发送，而是在根据第一个CCE计算出的PUCCH 1资源上发送。由此，网络设备可以分别在ACK/NACK资源和SR资源上做相应的解调和能量检测。上述专用资源，也即根据第一个CCE计算出的PUCCH 1资源，只是举例说明，本实施例并不以此作为限制。 In LTE, when a user equipment needs to simultaneously send a scheduling request (SR, Scheduling Request) and a HARQ ACK/NACK, the HARQ ACK/NACK is sent on the SR resource instead of the PUCCH 1 resource calculated according to the first CCE. (here we call it ACK/NACK resource) to send. At this time, nothing is sent on the ACK/NACK resource, that is, there is no energy. The network device knows whether the user equipment has sent the SR by comparing the energy detected on the ACK/NACK resource and the SR resource. According to the modulation mode of this embodiment, when the user equipment simultaneously transmits the SR and the HARQ ACK/NACK, the HARQ ACK/NACK is not transmitted on the SR resource, but is transmitted on the PUCCH 1 resource calculated according to the first CCE. Thereby, the network device can perform corresponding demodulation and energy detection on the ACK/NACK resource and the SR resource, respectively. The foregoing dedicated resource, that is, the PUCCH 1 resource calculated according to the first CCE, is only an example, and the embodiment is not limited thereto.

在LTE中，当用户设备处于非连续传输(DTX，Discontinuous Transmission)状态时，PUCCH上不会发送任何信号，包括数据和参考信号；此时和PUCCH 1a/1b发送ACK时非常类似，因为ACK映射为0，但是要注意PUCCH 1a/1b的参考信号是始终发送的，因此可以通过检测参考信号是否存在来区分DTX和PUCCH 1a/1b的ACK。具体检测方法可以通过接收端(例如网络设备)测量参考信号所在的时频位置的功率来实现，当该接收功率小于某个预定义的阈值时可以判决为DTX，否则说明此时不是DTX状态。In LTE, when the user equipment is in the Discontinuous Transmission (DTX) state, no signal, including data and reference signals, is transmitted on the PUCCH; this is very similar to the PUCCH 1a/1b sending ACK because of the ACK mapping. It is 0, but it should be noted that the reference signal of PUCCH 1a/1b is always transmitted, so the ACK of DTX and PUCCH 1a/1b can be distinguished by detecting the presence or absence of the reference signal. The specific detection method may be implemented by the receiving end (for example, the network device) measuring the power of the time-frequency position where the reference signal is located. When the received power is less than a certain predefined threshold, the DTX may be determined. Otherwise, the DTX state is not indicated.

在本实施例的一个实施方式中，当待调制信息为HARQ ACK/NACK时，如果该HARQ ACK/NACK以PUCCH格式2a或者PUCCH格式2b在PUCCH上发送，则可以将上述调制符号进一步调制到每个时隙的第二个参考信号符号中的部分子载波上，如图11所示，以进行发送。由此避免了当本实施例的星座点含有0，可能把一个符号中所有的参考信号置为0，造成信道估计不准确的问题。In an embodiment of the present embodiment, when the information to be modulated is HARQ ACK/NACK, if the HARQ ACK/NACK is transmitted on the PUCCH in PUCCH format 2a or PUCCH format 2b, the modulation symbol may be further modulated to each On some of the sub-carriers of the second reference signal symbol of the time slot, as shown in FIG. 11, for transmission. This avoids the problem that when the constellation point of this embodiment contains 0, it is possible to set all the reference signals in one symbol to 0, resulting in inaccurate channel estimation.

在本实施方式中，上述部分子载波的索引可以是预先定义的，也即预先定义好将上述调制符号调制到每个时隙的第二个参考信号符号中的哪些子载波上。In this embodiment, the index of the partial subcarrier may be predefined, that is, which subcarriers of the second reference signal symbol of each slot are modulated by the modulation symbol in advance.

在本实施例的一个实施方式中，当待调制信息为HARQ ACK/NACK时，如果该HARQ ACK/NACK以PUCCH格式1a或者PUCCH格式1b在PUCCH上发送，则可以利用最大允许功率发送上述调制符号。In an embodiment of the present embodiment, when the information to be modulated is HARQ ACK/NACK, if the HARQ ACK/NACK is transmitted on the PUCCH in PUCCH format 1a or PUCCH format 1b, the above modulation symbol may be transmitted by using the maximum allowed power. .

在本实施方式中，由于HARQ ACK/NACK采用了新的调制方式，可能不发送能量，因此，功率可以设为最大允许值，例如，在TS 36.213的5.1.2.1节中，将“For PUCCH format 1,1a and 1b,h(n_CQI,n_HARQ,n_SR)＝0”修改为“For PUCCH format 1,h(n_CQI,n_HARQ,n_SR)＝0，For PUCCH format 1a/1b,P_PUCCH(i)＝P_CMAX,c(i)”。In the present embodiment, since the HARQ ACK/NACK adopts a new modulation mode, energy may not be transmitted. Therefore, the power may be set to the maximum allowable value. For example, in Section 5.1.2.1 of TS 36.213, "For PUCCH format" 1,1a and 1b, h(n _CQI , n _HARQ , n _SR )=0” is modified to “For PUCCH format 1, h(n _CQI , n _HARQ , n _SR )=0, For PUCCH format 1a/1b, P _PUCCH (i) = P _CMAX,c (i)".
