Sidelink Radio Parameter Selection via Common Combination Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sidelink communication, the uniform configuration of radio parameters such as numerology, bandwidth part, and slot length can lead to communication failures when the transmission and reception destinations have different supported combinations, as the device may not be able to support the configured parameters.
Innovation Solution
A communication device that receives information on the supported radio parameter combinations from both the transmission and reception destinations, extracts the common combinations, and transmits this information to enable selection of parameters that both can support, allowing for successful communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform radio parameters are configured for sidelink communication, then communication simplicity is improved, but compatibility with devices having different supported combinations deteriorates
Solution Approach 1:
The transmitting device performs preliminary action by determining the combination of radio parameters before actual communication occurs. The device receives information about supported parameter combinations from both transmission and reception destinations, extracts common combinations, and selects appropriate parameters in advance. This preliminary determination ensures that both devices can support the selected parameters without requiring complex runtime negotiation, thus resolving the contradiction between communication simplicity and parameter compatibility.
2Adaptability or versatility
If radio parameter combinations are individually configured for each device, then parameter compatibility is improved, but communication complexity increases
Solution Approach 1:
The invention merges the parameter configuration processes of both transmitting and receiving devices by extracting common parameter combinations from both sides. Instead of independently configuring parameters for each device or performing complex multi-device negotiations, the system combines the supported combinations information from transmission and reception destinations, identifies overlapping compatible parameters, and selects from this merged set. This merging approach reduces communication complexity while ensuring compatibility.
3Adaptability or versatility
If common radio parameter combinations are extracted and selected, then parameter compatibility is improved, but information processing overhead increases
Solution Approach 1:
The system performs preliminary extraction of common parameter combinations before actual communication begins. By receiving supported combinations information from both transmission and reception destinations in advance and determining common combinations beforehand, the system avoids time-consuming parameter negotiations during active communication. This preliminary action minimizes information processing overhead during the communication phase while ensuring parameter compatibility.

AI summary
A communication device includes a receiving unit that receives information indicating a first set of combinations of radio parameters; a control unit that extracts, based on the first set of the combinations of the radio parameters and a second set of combinations of radio parameters supported by the communication device, a third set of combinations of radio parameters that are common between the first set and the second set; and a transmitting unit that transmits information indicating the third set of the combinations of the radio parameters.
