Abstract

A method for uplink transmission by a UE includes obtaining information regarding a plurality of power control sets each having a plurality of power control parameters, wherein a value of at least one parameter in a first power control set is different from a value of the at least one parameter in a second power control set; obtaining information associating at least one of the power control sets with at least one operational property of the UE; and when at least one of the operational properties is in effect on the UE, transmitting a PUSCH using the parameters of the power control set associated with the at least one operational property in effect.
