APPARATUS AND METHOD FOR INTER-BAND PAIRING OF CARRIERS FOR TIME DIVISION DUPLEX TRANSMIT- AND RECEIVE-SWITCHING AND ITS APPLICATION TO MULTIPLEXING OF DIFFERENT TRANSMISSION TIME INTERVALS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18482809 titled 'APPARATUS AND METHOD FOR INTER-BAND PAIRING OF CARRIERS FOR TIME DIVISION DUPLEX TRANSMIT- AND RECEIVE-SWITCHING AND ITS APPLICATION TO MULTIPLEXING OF DIFFERENT TRANSMISSION TIME INTERVALS

Simplified Explanation

The present disclosure relates to a method and system for pairing an inter-band carrier with a time division duplex (TDD) carrier. This pairing allows for full duplex operations in both frequency division duplex (FDD) and TDD bands.

• The patent application describes a method for pairing an inter-band carrier with a TDD carrier.
• If the paired band is an FDD band, additional thin control channels can be transmitted and received on FDD carriers to enable full duplex operations.
• If the paired band is a TDD band, a conjugate or inverse carrier can be used to achieve full duplex or a close approximation.
• The introduction of a paired channel and fast control channels allows for rapid uplink/downlink switching for TDD carriers.
• The patent application also claims and describes other aspects, embodiments, and features.

Potential applications of this technology:

• Wireless communication systems
• Mobile devices
• Base stations

Problems solved by this technology:

• Enabling full duplex operations in both FDD and TDD bands
• Efficient and effective uplink/downlink switching for TDD carriers

Benefits of this technology:

• Improved capacity and efficiency of wireless communication systems
• Enhanced performance of mobile devices and base stations
• Enables simultaneous transmission and reception of data in both FDD and TDD bands

Original Abstract Submitted

Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.
