1. A time-division multiplexed (TDM) communication system, comprising:
a first transceiver configured to receive data from a plurality of transceivers via a channel that is time-division multiplexed, the plurality of transceivers including at least a second transceiver and a third transceiver, the first transceiver configured to receive load information from the second transceiver indicating a load buffered by the second transceiver for transmission to the first transceiver; and
a dynamic bandwidth allocation (DBA) controller configured to allocate bandwidth to the plurality of transceivers, the DBA controller configured to determine an amount of bandwidth allocated to the second transceiver for transmissions from the second transceiver to the first transceiver occurring while the load information is propagating through the channel, the DBA controller configured to adjust the load indicated by the load information based on the determined amount of bandwidth allocated to the second transceiver such that the adjusted load accounts for transmissions by the second transceiver during propagation of the load information through the channel, the DBA controller further configured to allocate bandwidth to the second transceiver for transmissions to the first transceiver based on the adjusted load and to cause the first transceiver to transmit control information indicative of the bandwidth allocated to the second transceiver based on the adjusted load.
