Abstract
Official abstract text for this publication.
A time-frequency resource allocation planner for planning allocation of time-frequency resources to sustain communication links from a common transmitter (TX) to multiple receivers (RX 1 , . . . , RX K ) in a wireless OFDMA communication system includes a resource block selector configured to select a set (RBS) of time-frequency resource blocks (RB) for transmission of one packet for each communication link. A communication link quality measure provider is configured to determine a gain-to-interference-plus-noise ratio measure (G k ) for each communication link. A transmit power and transmit rate estimator, connected to the resource block selector and the communication link quality measure provider, is configured to jointly estimate, within the selected set of time-frequency resource blocks, transmit power (P k ) and transmit rate (R k ) of the packets as functions of determined gain-to-interference-plus-noise ratio measures, to at least approximately minimize expected transmitter energy consumption.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for planning allocation of time-frequency resources to sustain communication links from a common transmitter (TX) to multiple receivers (RX 1 , . . . , RX K ) in a wireless Orthogonal Frequency Division Multiple Access (OFDMA) communication system, the method comprising: selecting a set (RBS) of time-frequency resource blocks (RB) for transmission of one packet for each communication link; determining a gain-to-interference-plus-noise ratio…
