Question: In a PSCCH-PSSCH transmission occasion for NR (New Radio), how does a UE (User Equipment) determine the transmission power for a PSCCH (Physical Sidelink Control Channel) on a dedicated resource pool for SL (Sidelink) PRS (Positioning Reference Signal) transmissions?
Option 1: Based on the number of resource blocks allocated for PSSCH (Physical Sidelink Shared Channel) only.
Option 2: Same as the power of SL PRS transmission by the UE in the same slot.
Option 3: Dynamically adjusted based on the interference level from overlapping E-UTRA (Evolved Universal Terrestrial Radio Access) subframes.
Option 4: Calculated using a fixed power offset plus the number of resource blocks for both PSCCH and PSSCH transmissions.
Explanation: For a UE transmitting on a resource pool dedicated to SL PRS, the power for PSCCH transmission in a slot is determined to be the same as the power for SL PRS transmission in that slot. This ensures consistent power levels for coexisting sidelink transmissions, adhering to specifications for maintaining effective sidelink communication without undue interference.
