WIRELESS COMMUNICATION DEVICE FOR TRANSMITTING AND RECEIVING REFERENCE SIGNALS AND OPERATING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17939200 titled 'WIRELESS COMMUNICATION DEVICE FOR TRANSMITTING AND RECEIVING REFERENCE SIGNALS AND OPERATING METHOD THEREOF
Simplified Explanation
The abstract describes an operating method for a user equipment (UE) in a wireless communication system. Here are the key points:
- The UE receives configuration information from a base station regarding a Channel State Information-Reference Signal (CSI-RS), which includes the time and frequency location of a first CSI-RS.
- The first CSI-RS has a density value of 0.5, 1, or 3, indicating the number of resource elements used for transmitting the CSI-RS.
- Based on the channel characteristic between the UE and the base station, the UE determines whether to request a second CSI-RS with a different density value.
- If the UE decides to request the second CSI-RS, it sends a request message to the base station.
- The UE then receives the second CSI-RS from the base station, which is based on the request message.
- Using the second CSI-RS, the UE estimates the channel between itself and the base station.
- Finally, the UE transmits a CSI-RS report to the base station based on the channel estimate.
Potential applications of this technology:
- Wireless communication systems, such as cellular networks, where accurate channel state information is crucial for efficient resource allocation and beamforming.
- Internet of Things (IoT) devices that rely on wireless communication and require reliable channel estimation for optimal performance.
Problems solved by this technology:
- Efficient utilization of resources: By dynamically adjusting the density of CSI-RS based on channel characteristics, the system can optimize the allocation of resources.
- Improved channel estimation: The ability to request and receive CSI-RS with different density values allows for more accurate estimation of the channel, leading to better system performance.
Benefits of this technology:
- Enhanced system performance: Accurate channel estimation enables better resource allocation, beamforming, and overall system efficiency.
- Improved reliability: By adapting the density of CSI-RS based on channel conditions, the system can better handle varying wireless environments and maintain reliable communication.
- Flexibility: The ability to request and receive CSI-RS with different density values provides flexibility in adapting to changing channel conditions and optimizing resource allocation.
Original Abstract Submitted
An operating method of a user equipment (UE) includes receiving channel state information-reference signal (CSI-RS) configuration information from a base station including time and frequency location information of a first CSI-RS, the first CSI-RS corresponding to a first density value of 0.5, 1 or 3, determining whether to request a second CSI-RS having a second density value based on a channel characteristic, the second density value being different from the first density value, and the channel characteristic corresponding to a channel between the UE and the base station, transmitting a request message to the base station in response to determining to request the second CSI-RS, receiving the second CSI-RS from the base station based on the CSI-RS configuration information, the second CSI-RS being based on the request message, estimating the channel based on the second CSI-RS, and transmitting a CSI-RS report to the base station based on the channel estimate.
