Engineering Contradiction Analysis
1Measurement precision
If a UE monitors all configured SSB frequencies for SL resource selection, then resource selection accuracy is improved, but power consumption increases
Solution Approach 1:
The patent segments the SSB frequency monitoring process by dividing the set of configured SSB frequencies into multiple subsets. The UE monitors only a selected subset of these frequencies for sidelink resource selection rather than all frequencies, thereby reducing power consumption while maintaining adequate resource selection accuracy through selective monitoring.
Solution Approach 2:
The patent implements dynamic selection of which SSB frequency subset to monitor based on current sidelink conditions. The network can dynamically configure different SSB frequency subsets for different UEs or different time periods, allowing the system to adapt monitoring requirements to actual traffic conditions and power constraints.
2Adaptability or versatility
If the network configures multiple SSB frequencies for SL resource selection, then resource selection flexibility is improved, but device complexity increases
Solution Approach 1:
The patent segments the multiple configured SSB frequencies into distinct subsets that can be independently selected and configured. This segmentation allows the network to provide flexibility in resource selection by assigning different subsets to different UEs or scenarios, while the UE handles complexity by only processing its assigned subset rather than all possible frequencies.
Solution Approach 2:
The network acts as an intermediary that manages the complexity of multiple SSB frequency configurations. The network configures and assigns specific SSB frequency subsets to UEs, thereby providing resource selection flexibility at the network level while shielding individual UEs from the full complexity of managing all possible frequency configurations.

AI summary
A wireless device may receive one or more configuration parameters for a sidelink resource pool. The one or more configuration parameters may indicate a first resource selection procedure for the sidelink resource pool, a second resource selection procedure for the sidelink resource pool, and a priority threshold below which the second resource selection procedure is allowed. The wireless device may transmit, based on the configuration parameters, a sidelink transport block via one or more transmission resources of the sidelink resource pool.
