Title:
周波数選択性チャネルを介したデータパケットの送信のための時間周波数リソースを配分する方法
Document Type and Number:
Japanese Patent JP6433600
Kind Code:
B2
Abstract:
A scheduler allocates time-frequency resources of a predefined time period for transmitting latency-constrained and non latency-constrained data packets over a frequency selective channel. The scheduler: performs assignment of time-frequency resources for transmitting non latency-constrained data; then, possibly performs a revision of the assignment so that time-frequency resources are allocated to latency-constrained data packets instead of non latency-constrained data packets, said revision being performed by minimizing cost impact of the revision on a global performance metric related to the transmissions of said non latency-constrained data packets; and, allocates the time-frequency resources as assigned to the non latency-constrained data packets that did not incur the assignment revision, whereas the latency-constrained data packets that incurred the assignment revision are put aside for later scheduling.
