APPARATUS FOR TRANSMITTING DATA ON CONTENTION BASED RESOURCE IN RADIO COMMUNICATION SYSTEM AND METHOD THEREOF

摘要

The method for transmitting data on contention based resource in a radio communication system comprising steps of: a BS broadcasting a definition of uplink contention based resource groups and a criterion for a UE selecting a group; the UE selecting uplink contention based resource to transmit data according to the criterion for selecting a group. With the method according to present invention, data transmission service quality of UE in the border area of the cell may be ensured by providing an effective scheme and thus the uplink system capacity is improved.
