TIMING CONSIDERATIONS AND SWITCHING BETWEEN TIME DIVISION DUPLEXING PATTERNS IN FLEXIBLE BANDWIDTH PARTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17454682 titled 'TIMING CONSIDERATIONS AND SWITCHING BETWEEN TIME DIVISION DUPLEXING PATTERNS IN FLEXIBLE BANDWIDTH PARTS

Simplified Explanation

The abstract describes a patent application related to enabling full-duplex communication in a time division duplexing (TDD) band. The innovation involves configuring a network node (e.g., user equipment) to communicate in flexible bandwidth parts (BWPs) using BWP-specific TDD patterns, regardless of the TDD pattern configured for the underlying band. The patent also addresses the need for half-duplex communication in certain cases where it offers better performance or avoids self-interference.

• The patent application focuses on enabling full-duplex communication in a TDD band.
• It involves configuring a network node to communicate in flexible BWPs using BWP-specific TDD patterns.
• The innovation allows the network node to operate independently of the TDD pattern configured for the underlying band.
• The patent also addresses the need for half-duplex communication in certain scenarios.
• It provides timing considerations and switching indications for the network node to switch between BWP-specific TDD patterns and the TDD pattern of the underlying band.
• The switching indications can be based on factors like the number of transmission time intervals or a timer.

Potential Applications

• Wireless communication systems using time division duplexing (TDD) can benefit from this technology.
• It can be applied in various network nodes, such as user equipment (UE) or base stations, to enable full-duplex communication.
• The innovation can be implemented in 5G or future wireless networks to enhance communication efficiency.

Problems Solved

• The patent solves the problem of enabling full-duplex communication in a TDD band, which traditionally supports half-duplex communication.
• It addresses the issue of self-interference that can occur in full-duplex communication.
• The technology also provides a solution for situations where half-duplex communication offers better performance or higher throughput.

Benefits

• The innovation allows for more efficient use of TDD bands by enabling full-duplex communication.
• It provides flexibility in configuring bandwidth parts and TDD patterns, enhancing the adaptability of network nodes.
• The technology offers improved performance by allowing the network node to switch between full-duplex and half-duplex communication based on specific requirements.

Original Abstract Submitted

To enable full-duplex communication in a time division duplexing (TDD) band, a network node (e.g., a user equipment (UE)) may be configured to communicate in one or more flexible bandwidth parts (BWPs) using BWP-specific TDD patterns regardless of a TDD pattern configured for the underlying band. However, in some cases, half-duplex communication may offer better performance than full-duplex communication (e.g., when full-duplex communication may cause self-interference or there is a need for high throughput half-duplex communication). Accordingly, some aspects described herein relate to timing considerations and switching indications for indicating an interval in which the network node is to operate in the flexible BWP using the BWP-specific TDD pattern and switching between the BWP-specific TDD pattern and the TDD pattern of the underlying band (e.g., using switching indications based on a number or quantity of transmission time intervals and/or a timer, among other examples).
