Description

Data generation method and device, device and computer storage medium

Cross-reference to related applications

The present application is based on a Chinese patent application filed on Jan. 16, 2016, the entire disclosure of which is hereby incorporated by reference.

Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a data generation method and apparatus, a device, and a computer storage medium.

Background technique

The application scenarios of the 5th-generation (5G) communication technology include enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and high reliability low latency communication (Ultra Reliability Low). Latency Communication, URLLC). The eMBB scenario is used to support mobile broadband. The main service requirements are large data packet transmission, high data rate, and high spectrum efficiency. The mMTC scenario is used to support mass device communication. The main service requirements are mass equipment and small data packet transmission. Currently, the International Telecommunications Union (ITU) and the 3rd Generation Partnership Project (3GPP) have determined the design goal of supporting a connection density of 1 million devices per square kilometer; the URLLC scenario is used to support high Reliable low-latency communication, the main business demand is high reliability, low latency transmission.

For the demand of massive equipment and small data packet transmission in the 5G communication technology mMTC scenario, and the high reliability and low latency transmission of the URLLC scenario, the traditional communication process design based on terminal random access and base station scheduling control cannot be satisfied. The system access device has limited capacity, the access and data transmission process takes a long time, and the signaling overhead is large.

In order to meet the requirements of these 5G communication technologies, a scheduling-based transmission method can be considered. When the terminal device needs to transmit data, data transmission can be performed, thereby eliminating a long and complicated random access process and scheduling control process, thereby greatly reducing Transmission delay and signaling overhead.

For periodic services in a URLLC scenario, the traditional orthogonal access method based on semi-persistent periodic resource scheduling/reservation (for example, Semi-Persistent Scheduling, SPS) can be considered as an efficient dynamic scheduling-free, low-latency delay. Access method. Periodic resource scheduling/reservation matching the service occurrence period can ensure efficient resource utilization, and each user monopolizes resources without inter-user interference, and performance can be guaranteed.

For the event-triggered service in the URLLC scenario, the traditional periodic scheduling/reserved orthogonal resources are often not fully utilized. If the scheduling/reservation period of orthogonal resources is longer, the resource utilization ratio is higher, but the longer the average time that terminal access needs to wait, the more difficult it is to ensure ultra-low latency demand; if the orthogonal resource scheduling/reservation period The shorter the average time that terminal access needs to wait, the easier it is to ensure ultra-low latency requirements, but the higher the vacancy rate of resources and the lower the utilization rate.

In order to improve the utilization of periodic scheduling/reserved resources, one method is that multiple event-triggered service users share the same transmission resource (for example, a time-frequency resource block), which can reduce the vacancy rate of resources, but multiple multiple occurrences occur. When a user simultaneously accesses and transmits on the transmission resource, a collision occurs, which seriously affects the reliability of the URLLC service transmission.
