A method and apparatus for effectively facilitating grant scheduling is provided. The method may comprise transmitting, by a user equipment (UE), a grant request, wherein the grant request includes a UE power headroom (UPH) value, and receiving, from a Node B, a scheduling grant, wherein the scheduling grant is derived from the transmitted UPH. 1. A method of wireless communication in a time division synchronous code division multiple access (TD-SCDMA) system , comprising:transmitting, by a user equipment (UE), a grant request, wherein the grant request includes a UE power headroom (UPH) value; andreceiving, from a Node B, a scheduling grant, wherein the scheduling grant is derived from the transmitted UPH.2. The method of claim 1 , wherein the scheduling grant is derived by the Node B from the UPH by generating an SNR headroom value from the UPH claim 1 , and determining a code rate from the SNR headroom value using a look up table.3. The method of claim 1 , wherein the SNR headroom value is determined using a first equation for scheduled communications claim 1 , and a second equation for non-scheduled communications.4. The method of claim 1 , wherein the transmitting further comprises transmitting the grant request using a random access channel.5. The method of claim 1 , wherein the transmitting further comprises transmitting the grant request using a physical uplink channel.6. The method of claim 1 , wherein the receiving further comprises receiving the scheduling grant using an E-AGCH.7. The method of claim 1 , wherein the grant request is a non-scheduled request claim 1 , and wherein the receiving further comprises receiving the scheduling grant using an E-UCCH.8. The method of claim 1 , further comprising:incrementing a E-PUCH power up upon receiving a NACK from the Node B.9. An apparatus for wireless communication in a TD-SCDMA system claim 1 , comprising:means for transmitting, by a UE, a grant request, wherein the grant request includes a UPH value; ...
