METHOD AND APPARATUS FOR TRANSMITTING UPLINK DATA IN A WIRELESS ACCESS SYSTEM

摘要

PURPOSE: An uplink data transmission method in a wireless access system and an apparatus thereof are provided to prevent resources from being unnecessarily wasted and to reduce the control overhead on upper layers. CONSTITUTION: An MTC terminal receives uplink resource allocation data for uplink data transmission from a base station through a downlink control channel (S610). The MTC terminal receives sequence data, which is allocated to each terminal, from the base station in order to transmit uplink data to other terminals using a CDM method in a resource block pair domain within a sub frame (S620). After producing a sequence based on the received sequence data (S630), the MTC terminal transmits uplink data to the base station through the resource block pair domain (S640). [Reference numerals] (AA) MTC terminal(M2M); (BB) Base station; (S610) Uplink resource allocation through a downlink control channel(resource block allocation information, MCS information); (S620) Sequence data for CDM with other terminals; (S630) Produce a sequence; (S640) Transmit uplink data
