Abstract: A method and apparatus for assigning time slots in a TDMA transmission maintains a list of available time slots and at least one list of subsequently available time slots with respect to a current frame of a TDMA transmission. The available list and subsequently available list or lists are maintained for each connection supported by the TDMA transmission. The procedure continues by receiving at least one data transport request, which identifies a quantity of data to transmit. It is then determined whether at least one time slot is available for allocation in response to the data transport request. Such a determination is based on the quantity of data to transmit and information in the list of available time slots and information in the list of subsequently available time slots. The procedure continues by allocating at least one time slot for at least one frame when the at least one time slot is available for allocation.

Abstract: A base station power control for dynamically introducing transmission power to compensate for rain fade in a broadband wireless system operating at millimeter wave frequencies. The base station periodically polls a selected network interface unit at a customer site to obtain status information such as the power level of the received signal. Variations in the power level of the received signal, indicative of variations in the attenuation of the wireless link, are used by the base station power controller to appropriately adjust transmission power. Status information collected by the base station can also include signal to noise level data and the bit error rate.
