Abstract

The invention provides a pre-scheduling resource allocation method and apparatus for adaptively adjusting the resource allocation cycle. The method includes: determining whether data reception or data transmission exists in the resource allocation cycle; if not, adjusting the resource allocation cycle at least based on an adjusting rule of the resource allocation cycle; and determining whether data reception or data transmission exists in the adjusted resource allocation cycle.

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) ...
