MULTI-USER COMMUNICATION METHOD AND RELATED COMMUNICATION APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240106616 titled 'MULTI-USER COMMUNICATION METHOD AND RELATED COMMUNICATION APPARATUS
Simplified Explanation
The multi-user communication method described in the patent application involves utilizing phase precoding information to reduce channel correlation between overlapping channels on the same frequency domain resource. The method includes obtaining channel information for two channels, determining phase precoding information based on this information, and performing precoding to minimize channel correlation between the two channels.
- Obtaining channel information for two overlapping channels on the same frequency domain resource
- Determining phase precoding information based on the channel information
- Performing precoding to minimize channel correlation between the two channels
- Ensuring that phases of signals transmitted on symmetric subcarriers of each channel are opposite
- Achieving reduced channel correlation between the equivalent channels of the overlapping channels after precoding
Potential Applications
This technology could be applied in multi-user communication systems where multiple channels overlap on the same frequency domain resource.
Problems Solved
This method addresses the issue of high channel correlation between overlapping channels, which can lead to interference and reduced communication efficiency.
Benefits
The use of phase precoding helps optimize communication performance by reducing channel correlation between overlapping channels.
Potential Commercial Applications
This technology could be valuable in wireless communication systems, particularly in scenarios where multiple users are transmitting data on the same frequency domain resource.
Possible Prior Art
One possible prior art in this field is the use of precoding techniques to mitigate interference in multi-user communication systems.
What is the impact of reduced channel correlation on communication performance?
Reduced channel correlation can lead to improved signal quality and increased data transmission rates in multi-user communication systems.
How does phase precoding help minimize channel correlation between overlapping channels?
Phase precoding ensures that the phases of signals transmitted on symmetric subcarriers of each channel are opposite, which helps reduce channel correlation between the channels.
Original Abstract Submitted
a multi-user communication method includes obtaining first information indicating channel information of a first channel on a first frequency domain resource and second information indicating channel information of a second channel on the first frequency domain resource. the method also includes determining phase precoding information based on the first information and the second information. the first channel and the second channel overlap with each other on the first frequency domain resource. phases of signals transmitted on symmetric subcarriers of the first channel are opposite. phases of signals transmitted on symmetric subcarriers of the second channel are opposite. after precoding is performed based on the phase precoding information, channel correlation between an equivalent channel of the second channel and an equivalent channel of the first channel is less than channel correlation between the second channel and the first channel.
