摘要： A method of uplink resource allocation is disclosed. The method includes computing a set of utilities for each of a finite set of transmission modes with a processor across a plurality of user devices, each having multiple transmit antennas, and iteratively allocating uplink resource blocks (RBs) and transmission modes to the plurality of user devices until all users have been allocated or no allocation is found, by selecting a mode that has a highest incremental utility sum for each user across one or more RBs, determining which user has the highest incremental utility sum, allocating the mode and RBs associated with the highest incremental utility sum to the user, and removing the allocated user from consideration. Other apparatuses, systems, and methods also are disclosed.
