Abstract
Systems and methods for conveying and determining modulations schemes employed by co-scheduled users are disclosed. In addition, methods and systems for designing signaling schemes that convey such information are also disclosed. In accordance with one method, an index is received and a table of indices in which the received index denotes a plurality of different sets of modulation schemes is referenced. Further, one or more modulation schemes of at least one co-scheduled user is determined based on the referencing. In addition, data signals are received and are processed by utilizing the one or more modulation schemes.
Claims20
A method for determining modulation information of co-scheduled users comprising:
- receiving an index;
- referencing a table of indices in which the received index denotes a plurality of different sets of modulation schemes;
- determining at least one modulation scheme of at least one co-scheduled user based on the referencing;
- and
- receiving data signals and processing the data signals by utilizing the at least one modulation scheme.
A system for conveying modulation information of co-scheduled users comprising:
- a scheduler configured to determine a set of co-scheduled users, a respective total number of streams for each of the users and a respective modulation scheme for each of the users;
- a controller configured to reference a listing of sets of modulation schemes to determine a set of modulation schemes that conforms to the determined total numbers of streams for each of the users and conforms to the determined modulation schemes for each of the users and configured to reference a table of indices in which each index of a plurality of the indices denotes a respective plurality of different sets of modulation schemes in the listing to select indices from the table for transmission to the co-scheduled users that denote the determined set of modulation schemes;
- and
- a transmitter configured to transmit a different one of the selected indices to each of the respective users to permit each of the users to determine the modulation schemes assigned to at least one other co-scheduled user.
A computer readable storage medium comprising a computer readable program, wherein the computer readable program when executed on a computer causes the computer to perform a method for designing a signaling table to convey modulation information of co-scheduled users, the method comprising:
- determining possible combinations of modulation schemes for a total number of users based upon splits, wherein a split is a sequence of total numbers of streams respectively allocated to co-scheduled users that is arranged in decreasing order;
- and
- allocating indices to the determined combinations to generate the signaling table for use in conveying to a given user modulation schemes employed by users that are co-scheduled with the given user.
