METHOD AND APPARATUS FOR GRANT-FREE DATA TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18346519 titled 'METHOD AND APPARATUS FOR GRANT-FREE DATA TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The abstract describes a communication scheme and system that combines IoT technology and a 5G communication system to support faster data transfer rates than a 4G system.

  • The communication scheme includes intelligent services such as smart home, smart building, smart city, smart car, health care, digital education, retail business, and security and safety-related services.
  • The method involves a terminal in a communication system receiving a semi-persistent scheduling (SPS) configuration from a base station.
  • The terminal identifies physical downlink shared channels (PDSCH) corresponding to the SPS configuration.
  • If the PDSCHs overlap in time in a slot, the terminal determines the PDSCH with the lowest SPS configuration index.
  • The terminal then excludes the PDSCH with the lowest SPS configuration index and selects a PDSCH for data transmission.
  • The terminal receives data from the base station based on the determined PDSCH, which is not overlapped with an uplink symbol in the slot.


Original Abstract Submitted

A communication scheme and a system of converging an IoT technology and a 5generation (5G) communication system for supporting a higher data transfer rate beyond a 4generation (4G) system are provided. The communication scheme includes intelligent services (e.g. smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, and security and safety-related services), based on a 5G communication technology and an IoT-related technology. A method performed by a terminal in a communication system is provided. The method includes receiving, from a base station, a semi-persistent scheduling (SPS) configuration including an SPS configuration index; identifying at least one physical downlink shared channel (PDSCH) corresponding to the SPS configuration; identifying a PDSCH with a lowest SPS configuration index in case that the at least one PDSCH corresponding to the SPS configuration is overlapped in time in a slot; determining a PDSCH for data transmission based on excluding a PDSCH that is overlapped with the PDSCH with the lowest SPS configuration index from the at least one PDSCH; and receiving, from the base station, data based on the determined PDSCH, wherein the at least one PDSCH is not overlapped with a symbol indicated as an uplink in the slot.
