FIELD: radio engineering, communication.
SUBSTANCE: retransmission resource allocation method and apparatus for a wireless communication system for allocating a retransmission resource using a semi-persistent resource allocation message indicating a retransmission resource allocation are provided. The method includes receiving, at a mobile terminal, a semi-persistent resource allocation message; determining whether the semi-persistent resource allocation message indicates a retransmission resource allocation or a semi-persistent resource allocation, based on usage information included in the semi-persistent resource allocation message; and executing, when the semi-persistent resource allocation message indicates the retransmission resource allocation, a retransmission operation based on resource assignment information included in the semi-persistent resource allocation message.
EFFECT: indicating retransmission resource allocation and semi-persistent resource allocation.
