Half Duplex Frequency Division Duplex Collision Handling - A simplified explanation of the abstract

This abstract first appeared for US patent application 17759870 titled 'Half Duplex Frequency Division Duplex Collision Handling

The abstract describes a patent application for a user equipment (UE) that can detect and handle collisions in a half-duplex frequency division duplex (HD-FDD) network.

• The UE identifies a collision between cell-specific downlink reception and uplink transmission and implements a collision handling technique for HD-FDD.
• The UE performs cell-specific uplink transmission and downlink reception with a guard period to prevent overlapping transmissions or receptions.
• The technology enables efficient communication in HD-FDD networks by managing collisions and optimizing transmission timing.

Potential Applications:

• This technology can be used in mobile communication devices to improve network efficiency and reliability.
• It can enhance the performance of wireless networks by reducing interference and optimizing transmission schedules.

Problems Solved:

• Addresses collisions between uplink and downlink transmissions in HD-FDD networks.
• Improves the overall performance and reliability of communication systems.

Benefits:

• Enhances network efficiency and reliability.
• Optimizes transmission timing to reduce collisions and interference.
• Improves the user experience by ensuring seamless communication in HD-FDD networks.

Commercial Applications:

• This technology can be applied in the development of 5G and future wireless communication systems.
• It can be integrated into mobile devices, base stations, and network infrastructure to enhance network performance.

Questions about the technology: 1. How does this technology improve communication in HD-FDD networks? 2. What are the key features of the collision handling technique implemented by the UE?

Original Abstract Submitted

A user equipment (UE) is configured to determine that half-duplex frequency division duplex (HD-FDD) is enabled by a network with which the UE is communicating, identify a collision between a cell-specific downlink reception and a cell-specific uplink transmission and implement a HD-FDD collision handling technique. A UE may also be configured to determine that half-duplex frequency division duplex (HD-FDD) is enabled by a network with which the UE is communicating, perform a first cell-specific uplink transmission at a first time and perform a first cell-specific downlink reception at a second time, wherein a guard period represents a time duration between the first time and the second time during which the UE is not to perform a second different cell-specific uplink transmission or a second different cell-specific downlink reception.
