Time-division multiplexed systems and methods for reducing overestimation of bandwidth demand

A method, comprising:

• receiving, at a first transceiver, 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;
• receiving, at the first transceiver, load information from the second transceiver indicating a load buffered by the second transceiver for transmission to the first transceiver;
• determining 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;
• adjusting the load indicated by the load information based on the determined amount of bandwidth;
• allocating bandwidth to the second transceiver for transmissions to the first transceiver based on the adjusted load;
• and
• transmitting, to the second transceiver, control information indicative of the bandwidth allocated to the second transceiver based on the adjusted load.

• and
• transmitting, from the first transceiver to the second transceiver, control information indicative of the bandwidth allocated to the second transceiver for the second frame.

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, the first transceiver further configured to receive data in a plurality of frames, including at least a first frame and a second frame, from each of the plurality of transceivers, wherein data of the first frame is transmitted through the channel while the load information is propagating through the channel, and wherein data of the second frame is transmitted by the plurality of transceivers through the channel after the load information is received by the first transceiver;
• and
• a dynamic bandwidth allocation (DBA) controller configured to allocate bandwidth to the second transceiver for the first frame, wherein the first transceiver is configured to transmit to the second transceiver control information indicative of the bandwidth allocated to the second transceiver for the first frame, the DBA controller configured to adjust the load indicated by the load information received by the first transceiver based on the bandwidth allocated to the second transceiver for the first frame, the DBA controller further configured to allocate, based on the adjusted load, bandwidth to the second transceiver for the second frame, wherein the first transceiver is configured to transmit to the second transceiver control information indicative of the bandwidth allocated to the second transceiver for the second frame.
