First Claim
Patent Images
1. A method that facilitates efficiently providing scheduling information to a central scheduler, comprising:
- transmitting coarse scheduling information via an out-of-band channel to a base station; and
transmitting fine scheduling information via an in-band channel to the base station;
wherein transmitting the coarse scheduling information comprisesdetermining a first number of supportable subcarriers based on a buffer level,determining a second number of supportable subcarriers based upon a power constraint,identifying a minimum between the first number and the second number of supportable subcarriers, andtransmitting scheduling information that identifies a range including the identified minimum between the first number and the second number of supportable subcarriers.

Abstract
Systems and methodologies are described that facilitate efficiently providing scheduling information from an access terminal to a base station to enable effectuating scheduling decisions. Access terminals may transmit scheduling information in bifurcated requests. For instance, coarse scheduling information may be transferred utilizing a dedicated out-of-band channel, and fine scheduling information may be transmitted over an in-band channel.
