APPARATUS AND METHOD FOR RANDOM ACCESS AND SMALL DATA TRANSMISSION USING CONFIGURED RESOURCES IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18363334 titled 'APPARATUS AND METHOD FOR RANDOM ACCESS AND SMALL DATA TRANSMISSION USING CONFIGURED RESOURCES IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The disclosed patent application is about a method performed by a terminal in a wireless communication system to support a higher data transmission rate in a 5G or 6G communication system. The method involves transmitting a message A to a base station using a 2-step random access based on a configured grant small data transmission (CG-SDT) procedure. The message A includes a cell radio network temporary identifier (C-RNTI) medium access control (MAC) control element (CE). The terminal then receives a physical downlink control channel (PDCCH) addressed to the C-RNTI from the base station. The completion of the random access response reception of the 2-step random access depends on the ongoing CG-SDT procedure, the running of a CG-SDT time alignment timer, and the presence of an uplink grant in the PDCCH.

  • The patent application describes a method for terminals in a wireless communication system to achieve higher data transmission rates.
  • The method involves using a 2-step random access procedure based on a configured grant small data transmission (CG-SDT) procedure.
  • The terminal transmits a message A to the base station, which includes a cell radio network temporary identifier (C-RNTI) medium access control (MAC) control element (CE).
  • The terminal then receives a physical downlink control channel (PDCCH) addressed to the C-RNTI from the base station.
  • The completion of the random access response reception depends on the ongoing CG-SDT procedure, the running of a CG-SDT time alignment timer, and the presence of an uplink grant in the PDCCH.

Potential applications of this technology:

  • 5G and 6G wireless communication systems
  • High-speed data transmission in mobile networks
  • Internet of Things (IoT) devices requiring fast and reliable communication

Problems solved by this technology:

  • Increasing data transmission rates in wireless communication systems
  • Efficient random access procedures for improved network performance
  • Timely and reliable transmission of control information

Benefits of this technology:

  • Higher data transmission rates enable faster and more responsive communication.
  • The 2-step random access procedure improves network efficiency and reduces latency.
  • The CG-SDT procedure ensures reliable transmission of control information.
  • The technology can support various applications, including IoT devices and high-bandwidth services.


Original Abstract Submitted

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a terminal in a wireless communication system is provided. The method includes transmitting, to a base station, a message A of a 2-step random access based on a configured grant small data transmission (CG-SDT) procedure, wherein the message A includes a cell radio network temporary identifier (C-RNTI) medium access control (MAC) control element (CE), and receiving, from the base station, a physical downlink control channel (PDCCH) addressed to the C-RNTI, wherein a random access response reception of the 2-step random access is completed, in case that the CG-SDT procedure is ongoing, a CG-SDT time alignment timer for the CG-SDT procedure is running and the PDCCH includes an uplink grant.
