Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack specific details and effective methods for reporting Reference Signal Receiving Power (RSRP) for sidelink transmission, which is essential for estimating path losses and adjusting transmitting powers in wireless communication systems.
Innovation Solution
A method where user equipment (UE) receives and measures a reference signal to determine the RSRP, and then transmits attribute information including geographic and type information related to the RSRP to another UE, enabling accurate path loss estimation and power adjustments for sidelink transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RSRP reporting for sidelink transmission is implemented, then path loss estimation accuracy is improved, but specific reporting details and methods are still insufficient
Solution Approach 1:
The RSRP reporting mechanism is segmented into multiple components: RSRP measurement values, geographic information (location coordinates), and type information (reference signal type, transmission type). This segmentation allows each component to be reported separately, ensuring complete and structured information transmission for accurate path loss estimation.
Solution Approach 2:
The patent adds geographic dimension (location information) and classification dimension (type information) to the traditional RSRP reporting. By incorporating location coordinates and signal type identifiers, the reporting moves from a single-dimensional power value to a multi-dimensional information structure, enabling more precise path loss estimation.
2Measurement precision
If RSRP measurement and reporting is performed, then sidelink path loss can be estimated, but interference control and power efficiency are not optimized
Solution Approach 1:
The patent implements a feedback mechanism where receiving UEs measure RSRP of reference signals from transmitting UEs, calculate path loss, and report this information back to the transmitting UEs. This feedback loop enables dynamic power adjustment and effective interference control in sidelink transmissions.
Solution Approach 2:
The patent utilizes multiple parameters including RSRP measurement values, geographic location information, and type information to dynamically adjust power control parameters. By changing and optimizing these parameters based on reported data, the system achieves improved interference control and power efficiency.
3Loss of information
If attribute information including geographic and type information is transmitted with RSRP, then reporting completeness is improved, but communication overhead increases
Solution Approach 1:
The patent designs a universal reporting structure that can carry multiple types of information (RSRP values, geographic coordinates, type identifiers) in a standardized format. This multi-functional message structure reduces the need for separate communication channels and minimizes overall overhead while ensuring complete information transmission.
Data Source
AI summary
The present application relates to user equipment and a method for reporting reference signal receiving power (RSRP). A user equipment transmits a reference signal to another user equipment. After receiving the reference signal, another user equipment measures the reference signal for determining an RSRP. Another user equipment then transmits the RSRP and an attribute information corresponding to the RSRP to the user equipment. The user equipment receives the RSRP and the attribute information. The attribute information includes a geographic information, a type information of the RSRP, or a combination of the geographic information and the type information.
