Abstract
A method of transmitting data from a UE to an eNB is provided. In response to a data transmission request from a MTC application, the UE chooses a preamble ID based on the data size and transmits a random access preamble message to the eNB. The eNB returns a random access response message to the UE. The random access response message identifies resource allocated in an uplink channel and includes one or more transmission power control parameters associated with the second uplink channel. After determining that the data size is less than or equal to the allocated resources in the second uplink channel, the UE transmits a scheduled transmission message to the eNB using the allocated resource in the second uplink channel at a transmission power level determined by the one or more transmission power control parameters.
