Abstract

A method for implementing coordinated resource allocations includes establishing one or more wireless connections using a first channel with one or more endpoints via at least one remote transceiver. The method further includes determining a schedule that assigns a first number of resource blocks to each endpoint of the one or more endpoints. The method additionally includes receiving one or more neighboring transceiver schedules determined by one or more neighboring base stations. Each neighboring transceiver schedule indicating a different number of resource blocks assigned to each neighboring remote transceiver connected to the respective neighboring base station. The method also includes determining one or more time slots and subcarriers within the first channel to assign to each resource block for each endpoint of the one or more endpoints based on the schedule and the neighboring transceiver schedules. The method further includes determining a power distribution for each resource block for each endpoint.
