1. A computer-implemented method for performing frequency selective scheduling between a user equipment (UE) and a base station, the method comprising:

scanning and evaluating, by the UE, radio conditions of a plurality of sub-bands within a predetermined system bandwidth;

in response to the scanning and evaluating, suspending, by the UE, transmission;

selecting, by the UE, a sub-band within the predetermined system bandwidth, wherein the sub-band is selected based on a ranking of radio conditions of the plurality of sub-bands within the predetermined system bandwidth;

communicating the selected sub-band from the UE to the base station; and

receiving, by the UE, a resource block from the base station,

wherein the resource block is selected by the base station among a plurality of resource blocks within the selected sub-band communicated from the UE to the base station,

wherein receipt of the resource block within the selected sub-band occurs one or more transmit time intervals after communicating the selected sub-band from the UE to the base station,

wherein receipt of the resource block within the selected sub-band occurs one or more transmit time intervals after receiving, from the base station, a control message indicative of the selected sub-band carrying the resource block,

wherein the resource block supports data communication between the base station and the UE.

2. The method of claim 1 ,

wherein at least one transmit time interval separates communicating the selected sub-band and receiving the resource block.

3. The method of claim 1 ,

wherein receiving the resource block and communicating the selected-sub-band occur in adjacent transmit time intervals.

4. The method of claim 1 ,

wherein communicating the selected sub-band from the UE to the base station comprises communicating a Channel Quality Indicator (CQI) having the selected sub-band embedded therein.

5. The method of claim 1 , further comprising transmitting a resource assignment message from the base station to the UE,

wherein the resource assignment message

is indicative of the resource block and

transmitted using resources which the UE monitors in anticipation of receiving the resource assignment message.

6. The method of claim 5 ,

wherein the resource assignment message is transmitted using the resource block.

7. The method of claim 6 ,

11. The method of claim 1 ,

wherein the scanning and evaluating the radio conditions of the plurality of sub-bands includes evaluating the plurality of sub-bands following at least one of:

a sequential pattern,

a sweeping pattern,

a sub-sampled pattern or

a random pattern.

12. A system for performing frequency selective scheduling, the system comprising:

a user equipment (UE) configured to:

scan and evaluate radio conditions of a plurality of overlapping sub-bands within a predetermined system bandwidth;

in response to the scanning and evaluating, suspend, by the UE, transmission;

select a sub-band within the predetermined system bandwidth, and

transmit the selected sub-band from the UE to a base station,

wherein the sub-band is selected based on radio conditions from the plurality of overlapping sub-bands within the predetermined system bandwidth; and

the base station configured to receive the selected sub-band, select a resource block among a plurality of resource blocks within the selected sub-band transmitted from the UE to the base station, and transmit the resource block to the UE on the selected sub-band;

wherein the base station is configured to perform transmission of the resource block within the selected sub-band one or more transmit time intervals after transmission of the selected sub-band from the UE to the base station;

wherein the base station is configured to perform transmission of the resource block within the selected sub-band one or more transmit time intervals after transmitting, to the UE, a control message indicative of the selected sub-band carrying the resource block;

wherein the system is configured to use the resource block for data communication between the base station and the UE.

13. The system of claim 12 ,

wherein at least one transmit time interval separates transmission of the selected sub-band and transmission of the resource block.

14. The method of claim 12 ,

wherein transmission of the selected sub-band and transmission of the resource block is performed in adjacent transmit time intervals.

15. The system of claim 12 ,

wherein the UE is configured to communicate the selected sub-band to the base station by communicating a Channel Quality Indicator (CQI) having the selected sub-band embedded therein.

16. A computer-implemented method for performing frequency selective scheduling between a user equipment (UE) and a base station, the method comprising:

scanning and evaluating, by the UE, radio conditions of a plurality of sub-bands within a predetermined system bandwidth;

in response to the scanning and evaluating, suspending, by the UE, transmission;

selecting, by the UE, the plurality of sub-bands within a predetermined system bandwidth, wherein the plurality of sub-bands are ranked in terms of radio conditions of the plurality of sub-bands;

communicating the selected plurality of sub-bands from the UE to the base station; and

receiving, by the UE, a resource block from the base station,

wherein the resource block is selected by the base station among a plurality of resource blocks within a resource transmitting sub-band among the selected plurality of sub-bands communicated from the UE to the base station,

wherein receipt of the resource block within the resource transmitting sub-band occurs one or more transmit time intervals after communicating the selected plurality of sub-bands from the UE to the base station,

wherein receipt of the resource block within the resource transmitting sub-band occurs one or more transmit time intervals after receiving, from the base station, a control message indicative of the resource transmitting sub-band carrying the resource block,

wherein the resource block supports data communication between the base station and the UE.

17. The method of claim 16 ,

wherein the resource transmitting sub-band is ranked first among the selected plurality of sub-bands.

18. The method of claim 16 ,

wherein the resource transmitting sub-band is ranked lower than first among the selected plurality of sub-bands.
