Sidelink Positioning Resource Configuration via Signaling

The patent merges the resource pool configuration for PRS transmission with the existing SL communication resource pool configuration. The network device configures both PRS resource pool and SL communication resource pool using the same configuration signaling mechanism, allowing them to share similar resource spaces while maintaining distinct identification through configuration parameters. This integration approach ensures reliable PRS transmission without significantly increasing device complexity.

The patent introduces configuration signaling as an intermediary mechanism between the network device and terminal for resource pool determination. This intermediary carries the necessary configuration information (first configuration information for PRS resource pool, second configuration information for SL communication resource pool) that enables the terminal to accurately identify and use the appropriate resource pools for both PRS transmission and SL communication, resolving the ambiguity without requiring complex local determination mechanisms.

The patent applies preliminary action by having the network device perform resource configuration in advance through configuration signaling before the actual PRS transmission occurs. The configuration signaling pre-establishes the first configuration information for PRS resource pool and second configuration information for SL communication resource pool, including frequency domain resources, time domain resources, and their respective relationships. This preliminary configuration eliminates the need for real-time resource determination and ensures accurate resource allocation information is available when needed.

The patent implements feedback through the configuration signaling mechanism that provides the terminal with explicit information about resource allocation. The terminal receives and processes the configuration signaling containing detailed resource mapping information, which serves as feedback about how frequency and time domain resources are allocated for both PRS and SL communication. This feedback mechanism ensures the terminal accurately understands and executes the resource allocation without requiring complex operational procedures.

The patent applies segmentation by dividing the resource pool configuration into distinct first configuration information for PRS resource pool and second configuration information for SL communication resource pool. Although both pools may share overlapping frequency and time domain resources, the segmentation in configuration space allows the terminal to clearly distinguish between PRS transmission resources and SL communication resources through separate configuration parameters, preventing mutual interference while maintaining efficient resource utilization.

The patent implements local quality by assigning different identification characteristics and configuration parameters to the PRS resource pool and SL communication resource pool. The first configuration information includes specific parameters for PRS resource pool (first starting frequency, first ending frequency, first starting time, first ending time), while the second configuration information includes parameters for SL communication resource pool. This differentiation in local configuration quality enables the terminal to correctly identify and prioritize each type of transmission, preventing interference despite potential resource overlap.
