[0006] for figure 2 For the DL transmission shown in , since the data to be sent is located at the base station side, the base station does not need to perform the scheduling request process like UL transmission before data transmission, but the base station still needs to send the data and scheduling instructions to the UE, and the UE Decoding, which still takes a certain amount of time, thus increasing the delay

Abstract

The present invention provides a pre-scheduled resource allocation method and device for adaptively adjusting the resource allocation period. Wherein, the method includes: determining whether there is data reception or data transmission within the resource allocation period; if it is determined that there is no data reception or data transmission within the resource allocation period, at least based on the adjustment rules of the resource allocation period adjusting the resource allocation period; and determining whether there is data reception or data transmission within the adjusted resource allocation period.

Description

technical field [0001] The present invention generally relates to the field of wireless communication, and more specifically, relates to a method and device for pre-scheduled resource allocation for adaptively adjusting resource allocation periods. Background technique [0002] The 3rd Generation Partnership Project (3GPP) has approved a research project "Study on Latency reduction techniques for LTE" for Rel-13. The purpose of this research project is to study and improve packet data delay based on Rel-13. There are many existing applications and new applications that will appear in the future will benefit from the reduction of delay, and even require the reduction of delay, such as Web applications, real-time applications and mission-critical communication (Mission-criticalcommunication) applications. Packet data latency is not only important for the expected responsiveness of a system, but is also a parameter that affects throughput. In a 3GPP Long Term Evolution (LTE) ...
