Claim:
1. A method of transmitting data from a UE to an eNB, comprising: at the UE: generating a data transmission request, wherein the data transmission request identifies a transmission data size and data to be transmitted; choosing a preamble ID for the request, wherein the preamble ID is at least in part dependent on the data size; transmitting a random access preamble message to the eNB via a Physical Random Access Channel, wherein the random access preamble message includes the preamble ID; receiving a random access response message from the eNB via a Physical Downlink Shared Channel, wherein the random access response message identifies resource allocated in a Physical Uplink Control Channel and the random access response message includes one or more transmission power control parameters associated with the Physical Uplink Control Channel; and in accordance with a determination that the data size is less than or equal to the allocated resources in the Physical Uplink Control Channel, transmitting a scheduled transmission message including the data to be transmitted to the eNB using the allocated resource in the Physical Uplink Control Channel at a transmission power level determined by the one or more transmission power control parameters.
