Question: For a UE (User Equipment) supporting a Supplementary UpLink (SUL) configuration in Frequency Range 1 (FR1), what happens to the relevant side conditions specifying received power levels when there is a relaxation of receiver sensitivity (ΔRIB,c > 0 dB)?
Option 1: The side conditions remain unchanged, regardless of the ΔRIB,c value.
Option 2: The side conditions are decreased by an amount equal to ΔRIB,c for all downlink NR bands.
Option 3: The relevant side conditions (SSB_RP and Io) are increased by the amount Δ=ΔRIB,c defined for the corresponding downlink NR bands.
Option 4: The adjustment of side conditions depends on whether the UE is operating in SC (Single Carrier) or SUL mode.
Explanation: When a UE supports a SUL configuration in FR1 and there's a positive receiver sensitivity relaxation (ΔRIB,c > 0 dB), to maintain performance, the thresholds for received power levels (specifically SSB_RP and Io) are adjusted upwards. This adjustment is directly proportional to the amount of sensitivity relaxation (Δ=ΔRIB,c) and applies specifically to the corresponding downlink NR bands, ensuring the UE can effectively operate under these relaxed conditions without compromising its ability to receive signals adequately.
