Description

Uplink scheduling processing method, device and system

Technical field

The present disclosure relates to the field of communications, such as a method, apparatus, and system for processing uplink scheduling.

Background technique

Machine to Machine (M2M) communication is an important research topic of the 5th generation mobile communication technology (5th Generation, 5G), and an important application field of wireless communication in the future. In the M2M project, some application scenarios have higher requirements for communication delay, such as inter-vehicle communication, automatic control, virtual reality, and smart grid. These scenarios hope to minimize end-to-end latency so that the terminal can respond as quickly as possible.

In the Long-Term Evolution (LTE) system, data delay mainly includes data processing delay, transmission delay, and scheduling processing delay. The scheduling processing delay refers to the time when the scheduling information is sent from the base station to the user equipment to start the actual data transmission or reception according to the scheduling information. In the LTE system, downlink data transmission can be performed in the same subframe as the subframe in which the scheduling information is transmitted, so the delay of the downlink scheduling processing is short. However, the uplink data must be transmitted in the 4th subframe after the subframe in which the scheduling information is transmitted. Since the length of each subframe in the LTE system is 1 ms, the delay of the uplink scheduling processing is about 4 ms.

A fast uplink data transmission method may be adopted, that is, for service data of a certain application scenario, the base station may instruct the user equipment to perform corresponding uplink data transmission in the kth subframe after the subframe in which the scheduling information is received, to shorten the scheduling processing delay. Where k is the scheduling processing delay and k < 4. Since the scheduling processing delay of fast uplink data transmission is short, the user equipment needs to have more processing capability to decode the scheduling information and prepare the data to be transmitted within the allowed time (about k subframes).

The LTE system may have multiple user equipments, including traditional user equipments and user equipments with strong processing capabilities for fast uplink data transmission. Therefore, some user equipments may not be fast on the kth subframe indicated by the base station. Uplink data is sent.
