Abstract
An air time management method and apparatus for multi-access channel networks is provided, suitable for use when terminal stations operate with adaptive modulation. A specific modulation (default modulation) is defined for each terminal station (in a planning phase. During operation, when bandwidth is to be allotted to an uplink or downlink communication, a base station checks whether the concerned terminal station is operating with a modulation more robust (e.g. less efficient) than the default modulation. In so, the base station allocates a time slot to the communication that has a duration sufficient for transmitting less than all of a particular set of data with the default modulation. If not, the base station allocates a time slot to the communication that has a duration sufficient for transmitting all of a particular set of data with the current modulation.
