Select all the statement(s) which are correctly describing the U

Select all the statement(s) which are correctly describing the Uplink Power Control function/algorithm: 1. Uplink Power Control is trade-off between inter-cell interference and own cell throughput. 2. Closed Loop ULPC is UE oriented, SINR and RSSI target window power control steering. 3. Interference Aware ULPC replaces Closed Loop ULPC for PUSCH/SRS, but keeps OLPC algorithm untouched. 4. UL Interference Offset feature overcomes the impact of power restrictions on PUCCH by allocating PUCCH away from power restricted region.
