METHODS AND DEVICES FOR PROCESSING UPLINK SIGNALS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240120985 titled 'METHODS AND DEVICES FOR PROCESSING UPLINK SIGNALS
Simplified Explanation
The abstract describes a method for processing uplink signals in a wireless communication system, specifically by a Remote Radio Unit (RRU).
- The RRU obtains uplink signals from wireless devices at antenna elements of an antenna array.
- Each wireless device is associated with its own user layer.
- The method captures energy per user layer by combining the received uplink signals from the antenna array for each user layer into combined signals.
- This results in one combined signal per user layer, with combining based on channel coefficients of the wireless device associated with each user layer.
- The combined signals are then provided to a Baseband Unit (BBU).
Potential Applications
This technology can be applied in:
- 5G networks
- Internet of Things (IoT) devices
- Smart city infrastructure
Problems Solved
- Efficient processing of uplink signals
- Improved signal quality
- Enhanced network capacity
Benefits
- Increased data transmission speeds
- Reduced interference
- Enhanced overall network performance
Potential Commercial Applications
- Telecommunication companies
- Network equipment manufacturers
- IoT service providers
Possible Prior Art
One possible prior art could be the use of beamforming techniques in wireless communication systems to improve signal quality and coverage.
Unanswered Questions
How does this method handle interference from other wireless devices in the vicinity?
The abstract does not specify how the method addresses interference issues that may arise in a dense wireless environment.
What is the impact of this method on power consumption in the RRU and BBU?
The abstract does not mention the power efficiency of the proposed method and its implications on energy consumption in the network infrastructure.
Original Abstract Submitted
there is provided mechanisms for processing uplink signals. a method is performed by a rru. the method comprises obtaining uplink signals as received from wireless devices at antenna elements of an antenna array of the rru, each wireless device being associated with its own at least one user layer. the method comprises capturing energy per user layer by combining the received uplink signals from the antenna array for each user layer into combined signals, resulting in one combined signal per user layer. the combining for each individual user layer is based on channel coefficients of the wireless device associated with said each individual user layer. the method comprises providing the combined signals to a bbu.
