Abstract  Abstract

A user apparatus in a mobile communications system is disclosed. The user apparatus includes a unit which receives from a base station apparatus a downlink control signal including information for allocating a radio resource; a unit which determines depending on a channel status a pre-encoding matrix indicator (PMI) which indicates a pre-encoding matrix to be applied to multiple antennas of the base station apparatus; and a unit which transmits to the base station apparatus an uplink signal including the PMI wherein if the radio resource is allocated to a physical uplink shared channel of the user apparatus the PMI is transmitted using a part of the radio resource and wherein if the radio resource is not allocated to the physical uplink shared channel of the user apparatus the PMI is transmitted in a physical uplink control channel which is allocated in a fixed manner to the user apparatus.
