Description

Method and device for generating data

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for generating data.

Background

Application scenarios of the fifth Generation (5th-Generation, 5G) Communication technology and the future Communication technology in the related art include enhanced Mobile Broadband (eMBB), mass Machine Type Communication (mtc), high Reliability Low Latency Communication (URLLC). The eMBB scene is used for supporting a mobile broadband, and the main service requirements are large data packet transmission, high data rate and high spectrum efficiency; an mtc scenario is used to support mass device communication, main service requirements are mass devices and small data packet transmission, and a design target determined by the current International Telecommunications Union (ITU) and third Generation Partnership Project (3rd Generation Partnership Project, 3GPP) for a 5G mtc scenario is to support a connection density of 100 ten thousand devices per square kilometer; the URLLC scenario is used to support high-reliability low-delay communications, and the main service requirements are high-reliability low-delay transmission.

For the requirements of mass equipment and small data packet transmission in an mMTC scene and the requirements of high reliability and low time delay transmission in a URLLC scene, the traditional communication flow design based on terminal random access, base station scheduling control and the like cannot be met, and the main reasons are that the capacity of system access equipment is limited, the time consumption of the access and data transmission process is long, the signaling overhead is large and the like.

To meet these 5G communication technology needs and similar needs of future communication technologies, applicants have discovered that: it is contemplated that a scheduling-free based transmission method may be employed. When the terminal equipment needs to send data, the data can be sent, and a long and complicated random access process and a scheduling control process are omitted, so that the transmission delay and the signaling overhead can be greatly reduced.

In order to improve the utilization efficiency of the transmission resources, a plurality of users may be allowed to share the same transmission resources (e.g., time-frequency resource blocks) to perform Non-Orthogonal multiplexing, thereby implementing Non-Orthogonal Multiple Access (NOMA). The multiple users are accessed in a non-orthogonal way, which is equivalent to collision of transmission resources used by the users, and in order to ensure the performance of the multi-user non-orthogonal multiplexing transmission, an advanced receiver, such as an interference cancellation receiver, is required to be adopted.

Further, it is also contemplated to implement multiuser scheduling-free transmission based on codes or sequences, as well as non-orthogonal access. For example, a plurality of users spread their data to be transmitted by using spreading codes or spreading sequences with low cross-correlation and then transmit the data on the same transmission resource, so that the detection performance of the users can be ensured by the spreading codes with low cross-correlation. However, the user data needs to occupy more resources after being subjected to sequence spreading, for example, the spreading sequence length is L, and in order to accommodate the spread information, the transmission resource needs to be increased by L times. If the spreading code with low cross correlation is adopted, compared with the non-spreading mode, the spreading code with low cross correlation can support K × L times of users to transmit on the same transmission resource, it can be considered that the spreading code with low cross correlation can achieve K times of user overload rate, that is, the spreading code with low cross correlation has the potential to improve the system spectrum efficiency by times.

Therefore, the scheduling-free transmission and the non-orthogonal access of multiple users are realized based on the codes or the sequences, the multi-user detection performance is favorably ensured, and the spectrum efficiency of the system can be improved while the low-delay access is realized. The design of codes or sequences is very important, for example, a certain number of codes or sequences with low cross-correlation are beneficial to ensuring the performance of scheduling-free transmission and non-orthogonal access, and are beneficial to controlling the complexity of a system, so that efficient scheduling-free transmission and non-orthogonal access can be realized.

Currently, 3GPP organizations are studying to evaluate New Radio Access Technology (NR or New RAT) meeting the 5G requirements, and the transmission Technology based on the schedule-free, non-orthogonal multiple Access NOMA is a popular candidate for mtc, URLLC, eMBB, etc. scenarios, and 3GPP agrees to have non-orthogonal multiple Access NOMA as an issue at RAN #75 conference in 3 months of 2017.

However, NR has not determined the scheme of scheduling-free transmission and non-orthogonal multiple access adopted by NR, for example, whether to adopt code-based or sequence-based scheme for scheduling-free transmission and non-orthogonal multiple access, how to design specific codes or sequences, and the like.

An effective solution has not been found to the above technical problems in the related art.

In this application example, when the designated element in the sequence s2 is processed to obtain the sequence s3, the element with the index of 1 and the element with the index of 2 in the sequence s2 may also be processed to obtain s3, for example, the element with the index of 1 and the element with the index of 2 in the sequence s2 are multiplied by the element with the index of 2 in the sequence s2 to obtain the sequence s 3; alternatively, the element with index 1 and the element with index 2 in the sequence s2 are multiplied by the specified values, respectively, to obtain a sequence s3, where: if the index of the sequence s2 is 0, multiplying the element with index 1 and the element with index 2 in the sequence s2 by 1 or exp (i × 2/3 × pi), respectively, to the power of (2 × index of the sequence s2 ═ 0); if the index of the sequence s2 is 1, multiplying the element with index 1 and the element with index 2 in the sequence s2 by the power of exp (i × 4/3 × pi) or exp (i × 2/3 × pi) (2 × the index of the sequence s2 is 2), respectively; if the index of the sequence s2 is 2, the element with index 1 and the element with index 2 in the sequence s2 are multiplied by the power of exp (i × 2/3 × pi) or exp (i × 2/3 × pi) (index of 2 × sequence s2 equals 4), respectively.

Application example 10

In this application example, the sequence set a is a hadamard code sequence set including 4 sequences with length L equal to 4, and 4 sequence vectors with length 4 in the sequence set may form a hadamard matrix of order 4, as shown in table 37:

Obtaining a sequence s1 from the sequence set A; assuming that the index of the obtained sequence s1 is 0, then the sequence s1 is [1,1,1,1 ];

obtaining a sequence s2 from the sequence set A; assuming that the index of the obtained sequence s2 is 1, then the sequence s2 is [1, -1,1, -1 ];

processing the specified elements in the sequence s2, specifically converting the element-1 in the sequence s2 to the specified value 1i (or multiplying by-1 i), resulting in the sequence s3, then the sequence s3 is [1,1i,1,1i ];

further, processing the specified element in the sequence s 3; unlike application example 1 in which a specified element to be processed is not acquired and processed by an index of the specified element, the sequence s3 is subjected to a dot-product process with the sequence vector acquired in table 38 to obtain a sequence s 4; since the index of the sequence s2 is 1, a sequence vector [1,1,1, -1] can be obtained from table 38, and a sequence s4 obtained by point-multiplying the sequence s3 by the sequence vector is [1,1i,1, -1i ]; this operation is equivalent to multiplying the 3rd element in the sequence s3 by-1, and the other elements remain unchanged, with the same effect as in application example 1.
