Abstract: A method and apparatus for selecting a favored transmission slot for communicating non-voice data in conjunction with a voice-data communication. The slot, reflecting a favored power level and transmission rate for transmitting the non-voice data on a supplemental channel, is selected based upon the transmission power levels for voice-data transmitted by a base station to a remote station on a fundamental channel. The favored transmission slot is selected without the remote station messaging information to the base station concerning frequency channel or interference information for the supplemental channel.

Abstract: A method and apparatus for wireless communications wherein a base station transmits a signal to sending data to a subscriber station through a signal beam that sweeps through the coverage area of the base station. User data addressed to the subscriber station is buffered until the signal beam angle of the signal beam allows efficient transmission. The base station may alter the beam sweep speed or the shape of the beam's radiation pattern over time to maximize system efficiency and capacity.

Abstract: Techniques to (more accurately) estimate the transmit power available for data service in a future time period (e.g., the next frame). In accordance with one aspect, variation in the available transmit power over time is estimated. A first margin is then computed and used to account for the estimated variation in the available transmit power. The available transmit power at a future time instance (e.g., the beginning of the next frame) is predicted and reduced by the first margin to derive a more accurate estimate of the available transmit power for the next frame. In accordance with another aspect, variation in the required transmit power for a particular data user is estimated and used in scheduling data transmission to this data user. A second margin can be computed and used to account for the estimated variation in the required transmit power for the data user. Whereas the first margin accounts for variation in the (overall) available transmit power, the second margin is specific to the particular link conditions experienced by the data user.

Abstract: A method and apparatus for efficient candidate frequency search while initiating a handoff in a code division multiple access communication system . The method includes when the pilot signal is transmitted by the mobile stati on that is power controlled to a target receive level, the traffic channel powe r level is increased relative to the pilot channel to improve receiver performance. An improved feature is that the received pilot received at the base station stays the same while the receiver receives extra energy in the redundant traffic symbols received to enhance the probability of correctly decoding the received frame. The base station detects the absence of the mobile station transmitted signal from the frequency of interest. If the bas e station is aware of the starting time and duration of the absence, it can focus its detection during this predetermined time period. The performance c an be improved if the absence of the signal is spread across two frames at the frame boundary.
