A method for re-transmitting data through a reverse link in Packet Data communication system using automatic repeat request(ARQ) adjusting data retransmission energy to be reduced at a predetermined ratio of one receiving energy for an initial data transmission to other receiving energy for a data retransmission.
A data retransmission method comprising:
- mapping a transmission energy corresponding to at least one data rate;
- allocating a portion of a transmission energy determined by a reverse data rate control to the retransmission data and the rest portion of the transmission energy to a new transmission data to be transmitted;
- and
- transmitting the retransmission and new transmission data so as to correspond to the respective allocated transmission energy,
A data retransmission method comprising:
- updating an effective data rate in accordance with, at least one data rate control command;
- comparing the updated effective data rate to a data rate when a retransmission data to be retransmitted is initially transmitted;
- determining a data rate of a new transmission data to be transmitted and a transmission energy of the retransmission data in accordance with the comparison result;
- and
- transmitting the new transmission data and the retransmission data to correspond to the determined data rate of the new transmission data and the determined transmission energy.
A data retransmission method, comprising the steps of:
- receiving whether a retransmission of a data previously transmitted is carried out or not through an independent physical channel or a common channel for a dedicate data rate control;
- mapping a transmission energy corresponding to at least one data rate;
- allocating a portion of the transmission energy determined by the data rate control to a retransmission data to be retransmitted and another portion of the transmission energy to a new transmission data to be transmitted;
- and
- transmitting the retransmission data and the new transmission data corresponding to the allocated transmission energies.
A data transmission method using an Automatic Repeat reQuest(ARQ) through a reverse link in a packet data communication system controlling data retransmission energy to be reduced at a predetermined ratio of first transmission energy.
