Claims:WE CLAIM:
1. A method for providing an improved Non-Orthogonal Multiple Access (NOMA) in a wireless communication network, the method comprising:
dynamically creating, by a base station (BS), a plurality of user equipment (UE) groups within a network coverage area based on at least one of a modulation coding scheme (MCS) for each UE, a received signal power at each UE, and a mobility of each UE, wherein each of the plurality of UE groups comprises a plurality of UE’s;
determining, by the BS, an appropriate codeword for each of the plurality of UE groups; and
assigning, by the BS, the appropriate codeword to each of the plurality of UE groups.

2. The method of claim 1, further comprising initializing the BS with a plurality of configuration parameters.

3. The method of claim 1, wherein the plurality of UE groups are dynamically created at a pre-configured periodic interval.

4. The method of claim 1, wherein the plurality of UE groups are dynamically created upon admission of a new UE into the network coverage area or upon exit of an existing UE from the network coverage area.

5. The method of claim 1, wherein dynamically creating the plurality of UE groups comprises determining a validity of each of the plurality of UE groups based on a change in at least one of the MCS for each UE, the received signal power at each UE, the mobility of each UE in each of the plurality of UE groups.

6. The method of claim 5, further comprising determining an appropriateness of each of the plurality of valid UE groups based on a change in the appropriate codeword for each UE in each of the plurality of valid UE groups.

7. The method of claim 1, wherein dynamically creating the plurality of UE groups comprises:
determining a number of UE’s within the network coverage area;
categorizing at least one of a MCS level, a power level of the base station, and a mobility state;
determining at least one of the MCS for each UE, the received signal power at each UE, the mobility of each UE; and
dynamically creating the plurality of UE groups based on a commonality of at least one of the MCS level, the power level of the base station, and the mobility state.

8. The method of claim 1, wherein determining the appropriate codeword comprises determining a plurality of available codewords from a codebook.

9. The method of claim 1, wherein determining the appropriate codeword comprises correlating, for each of the plurality of UE groups, a codeword for each UE with a codeword for each of the other UE’s in a corresponding UE group.

10. The method of claim 1, wherein determining the appropriate codeword is based on at least one of a received signal power for each of the plurality of UE groups, and a signal to interference noise ratio (SINR) of each of the plurality of UE groups.

11. The method of claim 1, further comprising:
determining a signal power for each of the plurality of UE groups based on the corresponding appropriate codeword; and
allocating the signal power to each of the plurality of UE groups.

12. The method of claim 11, wherein allocating the signal power comprises:
transmitting the signal power to each UE within a UE group for each of the plurality of UE groups; and
validating a signal power received at each UE based on a pre-configured threshold power.

13. The method of claim 12, wherein validating the signal power comprises:
determining a deviation of the signal power received at each UE from the signal power determined for corresponding UE group; and
comparing the deviation against the pre-configured threshold power.

14. A system for providing an improved Non-Orthogonal Multiple Access (NOMA) in a wireless communication network, the system comprising:
at least one processor; and
a memory for storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
dynamically creating a plurality of user equipment (UE) groups within a network coverage area based on at least one of a modulation coding scheme (MCS) for each UE, a received signal power at each UE, and a mobility of each UE, wherein each of the plurality of UE groups comprises a plurality of UE’s;
determining an appropriate codeword for each of the plurality of UE groups; and
assigning the appropriate codeword to each of the plurality of UE groups.

15. The system of claim 14, wherein the plurality of UE groups are dynamically created at a pre-configured periodic interval, or upon admission of a new UE into the network coverage area, or upon exit of an existing UE from the network coverage area.

16. The system of claim 14, wherein dynamically creating the plurality of UE groups comprises:
determining a validity of each of the plurality of UE groups based on a change in at least one of the MCS for each UE, the received signal power at each UE, the mobility of each UE in each of the plurality of UE groups; and
determining an appropriateness of each of the plurality of valid UE groups based on a change in the appropriate codeword for each UE in each of the plurality of valid UE groups.

17. The system of claim 14, wherein dynamically creating the plurality of UE groups comprises:
determining a number of UE’s within the network coverage area;
categorizing at least one of a MCS level, a power level of the base station, and a mobility state;
determining at least one of the MCS for each UE, the received signal power at each UE, the mobility of each UE; and
dynamically creating the plurality of UE groups based on a commonality of at least one of the MCS level, the power level of the base station, and the mobility state.

18. The system of claim 14, wherein determining the appropriate codeword comprises:
determining a plurality of available codewords from a codebook; or
correlating, for each of the plurality of UE groups, a codeword for each UE with a codeword for each of the other UE’s in a corresponding UE group.

19. The system of claim 14, wherein determining the appropriate codeword is based on at least one of a received signal power for each of the plurality of UE groups, and a signal to interference noise ratio (SINR) of each of the plurality of UE groups.

20. The system of claim 14, wherein one or more operations for providing an improved further comprise:
determining a signal power for each of the plurality of UE groups based on the corresponding appropriate codeword; and
allocating the signal power to each of the plurality of UE groups by:
transmitting the signal power to each UE within a UE group for each of the plurality of UE groups; and
validating a signal power received at each UE based on a pre-configured threshold power, wherein validating comprises:
determining a deviation of the signal power received at each UE from the signal power determined for corresponding UE group; and
comparing the deviation against the pre-configured threshold power.
