    Abstract: Scheduling priorities are established for the transmission of data to mobile stations in a cellular communication system based on a channel condition or a data rate associated with each mobile station, where each mobile station may have different channel conditions or data rates. Channel conditions and data rates associated with each mobile station may be set when the mobile station is first added to a mobile station list or they may be recalculated for each transmission period.

    Abstract: A decision as to whether a mobile terminal (202) has transmitted an ACK, a NACK or a NULL from a received signal at a base station (201) is made by successively eliminating (303, 304, 307) one of the three possible transmitted symbols by sequentially applying decision rules that maximize network throughput by minimizing the sum of the weighted costs of making a decision based on the magnitude of the received signal.

    Abstract: A system and method to measure channel quality in terms of signal to interference plus noise ratio for the transmission of coded signals over fading channels in a communication system. A Viterbi decoder metric for the Maximum Likelihood path is used as a channel quality measure for coherent and non-coherent transmission schemes. This Euclidean distance metric is filtered in order to smooth out short term variations. The filtered or averaged metric is a reliable channel quality measure which remains consistent across different coded modulation schemes speeds. The filtered metric is mapped to the signal to interference plus noise ratio per symbol using a threshold based scheme. Use of this implicit signal to interference plus noise ratio estimate is used for the mobile assisted hand off in a cellular system, power control and data rate adaptation in the transmitter.
