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.

摘要： Methods and systems for allocating resources in a cellular uplink include iteratively allocating uplink resource blocks (RBs) to a plurality of user devices in a multiple-input multiple-output network. Allocation is performed subject to constraints and incremental utility maximization according to an approximation that has a worst-case guarantee.

摘要： A method for LTE or WiMAX scheduling includes collecting, by a basestation BS, channel feedback from multiple mobiles with downlink traffic. The channel feedback enables the BS to determine an achievable rate or block error probability if transmitting to a mobile with a given modulation and coding scheme MCS and multiple-input multiple-output MIMO mode. The method includes determining, by the BS, which of the mobiles is scheduled on each resource block RB and what the MCS and MIMO mode is selected for each scheduled mobile, and allocating bits on the set of the RBs assigned to each scheduled mobile.
