    摘要： Information is transmitted over selected, Orthogonal Frequency Division Multiplexed (OFDM) sub-channels to avoid frequencies with unacceptable congestion, noise or interference levels. Using frequency hopping, selected non-contiguous OFDM sub-channels used for transmission may vary with time. Once a group of OFDM sub-channels is selected, a power level and modulation technique may also be selected based on channel quality.

    摘要： Methods and apparatuses for allocating control and data time slots to a plurality of wireless mobile stations in a wireless communication system using time division multiplexing. The methods and apparatuses assign such time slots by first placing the wireless mobile stations into a number of different groups. Then, control time slots and anchor data time slots are assigned to the groups in the uplink and downlink frames of a carrier such that the uplink control time slot for each group is maximally spaced in time relative to the downlink control time slot for the same group. Data time slots are subsequently assigned to a particular mobile station by assigning time slots in the uplink and downlink frames which are as close as possible to the group's uplink or downlink anchor data time slots, as the case may be, according to a “grow from center” technique.

    摘要： In the dynamic access priority method, priority classes with different backoff delays are used to prioritize random access over shared channels and to reduce collision in the presence of a surge of random access requests. Service class information for a plurality of service classes is stored at user equipment. The service class information for a service class includes at least one of a maximum and a minimum back off value; the maximum back off value being indicative of a maximum back off interval and the minimum back off value being indicative of a minimum back off interval. At least one of a maximum and a minimum back off value is determined based on a selected service class of the user equipment, and a back off interval is determined based on the determined back off value. The back off interval indicates a period of time the user equipment waits before the user equipment attempts a transmission.

    摘要： Disclosed are various embodiments providing processing circuitry for selecting a channel estimation filter from a plurality of channel estimation filters based on a channel quality metric, the selected channel estimation filter being associated with an intrinsic coefficient. The processing circuitry may then determine a scaled coefficient, the scale coefficient being based on scaling the intrinsic coefficient with respect to a bit size constraint, the bit size constraint being determined by a bit length of a multiplication circuitry operand. Moreover, the processing circuitry may generate an output based on the scaled coefficient and an input signal.
