AI Technical Summary

Technical Problem

Existing wireless communication systems face challenges in efficiently transmitting and receiving data and control channels, particularly in cellular networks, due to dynamic changes in uplink and downlink traffic demands.

Method used

A method and apparatus that utilize a preemption indicator to dynamically adjust resource allocation by classifying OFDM symbols into uplink, downlink, and flexible symbols, using a preemption indicator that is monitored periodically to determine resource availability and decode data effectively.

Benefits of technology

This approach enhances the efficiency of signal transmission and reception in wireless communication systems by optimizing resource utilization based on traffic direction, thereby improving spectral efficiency and reducing latency.

Abstract

To provide a wireless communication method, apparatus, and system for transmitting and receiving data channels and control channels.SOLUTION: A base station of a wireless communication system is disclosed. The base station of the wireless communication includes a communication module, and a processor. The processor generates a preemption indicator indicating a preempted resource. In this case, the resource indicated by the preemption indicator does not include an Orthogonal Frequency Divisional Multiplexing (OFDM) symbol configured as an uplink (UL) symbol by a radio resource control (RRC) signal. The processor transmits the preemption indicator to a terminal of the wireless system based on a predetermined period.SELECTED DRAWING: Figure 32
