APPARATUS FOR DATA TRANSMISSION METHOD
First Claim
1. An user equipment, comprising:
- a RF transceiver that receives broadcast information from a base station, wherein the broadcast information comprises at least one specific resource pool and at least one non-specific resource pool for a random access preamble; and
a processor that utilizes the at least one specific resource pool to perform a random access (RA) procedure of data transmission when the user equipment meets at least one condition, and generates a media access control (MAC) package data unit (PDU) in message 3 (MSG
3) in the allocated UL resource, wherein the MAC PDU comprises data available for transmission from an application layer;
the RF transceiver is further configured to receive random access response (RAR) from the base station, wherein the RAR comprises allocated uplink (UL) resource; and
the RF transceiver transmits the MAC PDU in MSG 3 in the allocated UL resource to the base station.

Abstract
This invention proposes efficient data transmission methods in the mobile cellular network. A specific resource pool is divided into several resource groups to indicate the size level of the data available for transmission. The base station allocates a proper UL grant to the terminal. Based on the allocated UL grant, the terminal compares the granted Transport Block (TB) size with the size of data available for transmission. If the UL grant is large enough, the terminal transmits the data available for transmission in the allocated UL resource, otherwise, re-attempts the random access procedure. In another example, the terminal transmits a BSR message and as much of the data as is available for transmission. The base station may grant additional UL resources if there is remaining data to be transmitted. A timer is used for the terminal to decide whether waiting for the additional UL grant from the base station.
