COMMUNICATION APPARATUS AND COMMUNICATION METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18752233 titled 'COMMUNICATION APPARATUS AND COMMUNICATION METHOD

Simplified Explanation:

This patent application describes a communication apparatus that is a second communication device with reduced communication capabilities compared to a first communication device. The apparatus includes a controller that performs a random access procedure using a specific initial BWP for the second communication device, which is a part of the bandwidth of a cell of a base station in an RRC idle state or an RRC inactive state. The controller switches the specific initial BWP to an initial BWP with a CD-SSB when the random access procedure fails and no CD-SSB is present on the specific initial BWP.

  • The communication apparatus is a second device with reduced communication capabilities compared to a first device.
  • The controller performs a random access procedure using a specific initial BWP for the second communication device.
  • The specific initial BWP is a part of the bandwidth of a cell of a base station in an RRC idle state or an RRC inactive state.
  • The controller switches the specific initial BWP to an initial BWP with a CD-SSB when the random access procedure fails.
  • This innovation aims to improve the efficiency of communication procedures in devices with reduced capabilities.

Potential Applications: - Mobile communication devices - Internet of Things (IoT) devices - Smart home systems

Problems Solved: - Enhancing communication efficiency in devices with limited capabilities - Improving random access procedures in communication devices

Benefits: - Faster and more reliable communication procedures - Better utilization of available bandwidth - Enhanced connectivity for devices with reduced communication capabilities

Commercial Applications: Title: Enhanced Communication Apparatus for IoT Devices This technology could be applied in IoT devices to streamline communication processes and improve overall connectivity. It could be marketed to IoT manufacturers looking to enhance the performance of their devices in various industries such as smart home automation, industrial IoT, and healthcare.

Prior Art: Prior art related to this technology may include patents or research papers on improving communication procedures in devices with limited capabilities, optimizing random access procedures in wireless communication systems, and enhancing connectivity in IoT devices.

Frequently Updated Research: Researchers in the field of wireless communication systems may be conducting studies on optimizing communication procedures for devices with reduced capabilities, improving the efficiency of random access procedures, and enhancing connectivity in IoT devices.

Questions about Communication Apparatus: 1. How does the controller determine when to switch the specific initial BWP to an initial BWP with a CD-SSB? 2. What are the potential challenges in implementing this technology in IoT devices?


Original Abstract Submitted

A communication apparatus that is a second communication apparatus having a communication capability reduced as compared with a first communication apparatus having a designated communication capability, the communication apparatus includes: a controller configured to perform a random access procedure using a specific initial BWP for the second communication apparatus, which is a bandwidth part (BWP) that is a part of a bandwidth of a cell of a base station in a radio resource control (RRC) idle state or an RRC inactive state. The controller is configured to switch the specific initial BWP to an initial BWP in which a CD-SSB is present, when the random access procedure has failed, in a case where no cell defining-synchronization signal block and physical broadcast channel block (CD-SSB) is present on the specific initial BWP.
