Processing method for reducing uplink transmission time delay, base station and terminal equipment

Abstract

The application provides a processing method for reducing uplink transmission time delay, a base station and terminal equipment. The method comprises the following steps: receiving a semi-static resource allocation request including a bandwidth demand sent by the terminal equipment; and periodically allocating pre-authorized uplink spectrum resources to the terminal equipment according to a current uplink semi-static resource allocation situation and the bandwidth demand. Through the processing method, the base station and the terminal equipment in the embodiment of the application, differentallocation strategies can be adopted according to an actual demand situation of the terminal equipment, thereby effectively shortening null interface and end-to-end time delays of a wireless communication system.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a processing method for reducing uplink transmission delay, a base station and terminal equipment. Background technique [0002] Currently, a Long Term Evolution (LET for short) wireless communication system provides an uplink scheduling request (Scheduling Request, SR for short), so that a user equipment (User Equipment, UE for short) needs to notify a base station that an evolved Node B (evolved Node B) (eNodeB for short) whether it has uplink data to transmit, so that the eNodeB decides whether to allocate uplink resources to the UE, so as to avoid that if the UE has no uplink data to transmit, the eNodeB does not need to allocate uplink resources for the UE, resulting in waste of resources. [0003] However, the UE tells the eNodeB whether it needs uplink resources for (uplink shared channel) UL-SCH transmission through the SR, but does not tell the eNo...

Problems solved by technology

[0004] With the development of applications such as unmanned driving and industrial control, most of the data sent is control information, and the amount of information is not large, but the requirements for real-time performance are very high. Therefore, wireless communication systems have more and more requirements for air interface and end-to-end delay. High, at the same time, the limited wireless resources determine the above SR process, but the above SR process requires a request and authorization between the base station and the terminal, and the process of applying for re-authorization, resulting in a large delay
