Abstract
A base station has a transmission element to wirelessly transmit at least one data frame. The at least one data frame has a predetermined uplink allocation and a predetermined downlink allocation. A detection element detects a congestion condition. When the congestion condition is detected, the transmission element transmits a request to at least one neighboring base station for an expansion of the predetermined uplink allocation or the predetermined downlink allocation. A reception element receives a signal from the at least one neighboring base station. A processing element expand the one of the predetermined uplink allocation or the predetermined downlink allocation by a specified amount in response to the signal indicating the specified amount for a mutually agreed time, or number of symbols or frames.
