Abstract
Methods for use in code division multiple access (CDMA) communication systems includes identifying signal strength needs (in terms of Eb/No) of wireless devices in a sector of a base station. Signal strength needs are determined as a function of the rate of movement of the wireless devices within the sector. The methods include dynamically adjusting the signal strength to a given Eb/No level for each of the wireless devices as a function of the needs of the majority of wireless devices in the sector, dynamically adjusting the signal strength to given Eb/No levels for different classes of wireless devices as a function of the needs of each class of wireless devices in the sector, and dynamically adjusting the signal strength to given Eb/No levels for each individual wireless device as a function of the need of each wireless device.
