Abstract  Abstract

A user device 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.

A user device includes: means for receiving a downstream control signal containing radio resource allocation information from a base station device; means for deciding a precoding matrix indicator (PMI) indicating a precoding matrix applied to a plurality of antennas of the base station device according to a channel state; and means for transmitting an upstream signal containing the PMI to the base station device. When a radio resource is allocated to the upstream physical shared channel of the user device the PMI is transmitted by a part of the radio resource. When no radio resource is allocated to the upstream physical shared channel of the user device the PMI is transmitted by an upstream physical control channel which is fixedly allocated to the user device.
