Abstract:
1. A method to manage a buffer of a base station (BS) in a communication system, the method comprising: monitoring a queue length of the buffer; when the queue length is less than a lower threshold and a previous flag comprises a first value indicating a congestion state, setting a current flag as a second value indicating a non-congestion state; when the queue length is greater than an upper threshold and the previous flag comprises the second value, setting the current flag as the first value; when the current flag is set different from the previous flag, transmitting a current flag value to a node and updating the upper threshold; and when one of a first case, a second case, or a third case is satisfied, maintaining the upper threshold, wherein the first case comprises that the queue length is less than the lower threshold and the previous flag comprises the second value, wherein the second case comprises that the queue length is greater than the upper threshold and the previous flag comprises the first value, and wherein the third case comprises that the queue length is no greater than the upper threshold and no less than the lower threshold.
