SIGNAL ESTIMATION FOR INTERFERENCE CANCELLATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17530354 titled 'SIGNAL ESTIMATION FOR INTERFERENCE CANCELLATION

Simplified Explanation

Methods, systems, and devices for wireless communication are described in this patent application. The innovation aims to estimate interference for concurrent uplink and downlink communications based on characteristics of an interfering uplink signal communicated between a base station and a second user equipment (UE). Here is a simplified explanation of the abstract:

• The patent application proposes a method to estimate interference in wireless communication.
• It focuses on concurrent uplink and downlink communications.
• The interference estimation is based on characteristics of an interfering uplink signal.
• The base station or second UE transmits an indication of the uplink signal's characteristics to a first UE.
• The first UE uses these characteristics to estimate the baseband of the uplink signal.
• By estimating the interference, the first UE can cancel it from the downlink signal it receives.

Potential Applications

This technology has potential applications in various wireless communication systems, including:

• Cellular networks
• Wi-Fi networks
• Satellite communication systems
• Internet of Things (IoT) devices

Problems Solved

The patent application addresses the following problems in wireless communication:

• Interference between uplink and downlink signals can degrade the quality of communication.
• Concurrent uplink and downlink communications require efficient interference estimation and cancellation techniques.
• Traditional methods may not accurately estimate and cancel interference, leading to reduced performance.

Benefits

The proposed innovation offers several benefits in wireless communication:

• Improved signal quality by canceling interference from uplink signals.
• Enhanced performance of concurrent uplink and downlink communications.
• More reliable and efficient wireless communication systems.
• Better user experience with reduced interference-related issues.

Original Abstract Submitted

Methods, systems, and devices for wireless communication are described to estimate interference for concurrent uplink and downlink communications based on an indication of one or more one or more characteristics of an interfering uplink signal communicated between a base station and a second user equipment (UE). The base station or the second UE may transmit, to a first UE, an indication of one or more characteristics of an uplink signal, such as a baseband of the uplink signal or one or more parameters of the uplink signal. The first UE may use the characteristic(s) of the uplink signal to estimate the baseband of the uplink signal and cancel interference associated with the uplink signal. For example, the first UE may use the baseband signal to estimate the interference and may subtract the estimated interference from a downlink signal received at the first UE.
