Base station apparatus, mobile station apparatus, method for mapping a response signal, and method for determining a response signal resource
First Claim
1. A base station apparatus comprising:
- a processor configured to;
allocate, to a mobile station, a plurality of uplink resource blocks, the resource blocks being consecutive in a frequency domain and indices of the plurality of consecutive resources blocks being respectively associated with a plurality of resources of downlink which are different in a frequency domain;
map an ACK or NACK signal for uplink data to at least one of the resources of downlink, the one of the resources being determined from an index of the allocated resource block within the indices of the plurality of consecutive resource blocks;
a transmitter configured to transmit the mapped ACK or NACK signal to the mobile station.

Abstract
Provided is a radio communication base station device which can obtain a maximum frequency diversity effect of a downstream line control channel. The device includes: an RB allocation unit (101) which allocates upstream line resource blocks continuous on the frequency axis for respective radio communication mobile stations by the frequency scheduling and generates allocation information indicating which upstream line resource block has been allocated to which radio communication mobile station device; and an arrangement unit (109) which arranges a response signal to the radio communication mobile station device in the downstream line control channels distributed/arranged on the frequency axis while being correlated to the continuous upstream line resource blocks according to the allocation information.

28. A method in a mobile station apparatus comprising:
-
receiving, from a base station, allocation information indicating one or a plurality of uplink resource blocks, the resource blocks being consecutive in a frequency domain; and
indices of the plurality of consecutive resource blocks being respectively associated with a plurality of resources of downlink which are different in a frequency domain;making a determination with a processor, based on the allocation information, at least one of the resources of downlink, to which an ACK or NACK signal for uplink is mapped, from an index of the allocated resource block within the indices of the plurality of consecutive resource blocks, the ACK or NACK signaling being transmitted from the base station.
