METHOD AND DEVICE FOR ALLOCATING TIME-FREQUENCY RESOURCES TO DATA PACKET TO TRANSMIT DATA PACKET THROUGH COMMUNICATION NETWORK, COMPUTER PROGRAM FOR EXECUTING THE SAME METHOD AND INFORMATION STORAGE MEANS FOR STORING THE SAME COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a technique for satisfying a delay restriction accompanying an increased processing amount when scheduling a frequency selective fading channel.

SOLUTION: A scheduler obtains data packets each of which is either a latency-constrained data packet or another data packet, and obtains information about transmission conditions. Then, for each latency-constrained data packet, the scheduler determines each candidate time-frequency resource that can be used for transmitting the latency-constrained data packet. Then the scheduler performs the following steps: allocating time-frequency resource to the respective latency-constrained data packets, when the number of time-frequency resource needed for transmitting the latency-constrained data packet is equal to the number of determined candidate time-frequency resources for the latency-constrained data packet; and otherwise, reserving time-frequency resource for transmitting at least one other data packet.
