Abstract:
1. A mobile communication system, comprising: a base station apparatus configured to: transmit resource allocation information for specifying an uplink resource for mapping data onto a physical uplink shared channel (PUSCH), wherein the uplink resource contains at least a plurality of symbols in a time domain; and a mobile station apparatus configured to: receive, from the base station apparatus, the resource allocation information for specifying the uplink resource for mapping the data onto the PUSCH; calculate, based on the resource allocation information for specifying the uplink resource for mapping the data onto the PUSCH, a quantity of positive acknowledgement (ACK) or negative acknowledgement (NACK) modulation symbols in the PUSCH that are available to carry ACK or NACK for downlink data in the uplink resource; map ACK or NACK modulation symbols onto part of the symbols in the time domain of the uplink resource, wherein the quantity of the mapped ACK or NACK modulation symbols is equal to or less than the calculated quantity of the ACK or NACK modulation symbols in the PUSCH that are available to carry the ACK or the NACK for the downlink data in the uplink resource, and does not exceed a predetermined amount; and transmit, to the base station apparatus, the mapped ACK or NACK modulation symbols together with uplink data in the uplink resource.
