    Abstract: A method that adjusts the power level of a set of forward-link signals of a base station responsive to the loading of the forward link as determined by a power level measurement of the signal set. One power level measurement is a pilot fraction of the forward link. Other power level measurements, such as the signal set's power level, can be used, alone or in combination, instead of or in addition to the pilot fraction of the forward link to adjust the power level of the signal set. The power level of the signal set can be changed in any manner, including by scaling it by a scaling factor, or by increasing the power level by a fixed or a variable amount. The power level measurement of the signal set is obtained during a current time period. The scaling factor that will be used in the subsequent time period is determined using the power level measurement. In one embodiment of the invention, the scaling factor can be obtained from a look-up table that is based on the power level measurement. If the cell containing the base station includes several sectors, the power level of the signal set in a sector is adjusted when the power level measurement in that sector indicates that the power level should be adjusted.

    Abstract: In order to effectively terminate a burst transmission in a wireless system, a method and apparatus determines whether or not a burst transmission from a wireless unit to a base station should be terminated by evaluating at least one criterion related to the operation of the wireless system. Once it is determined that a burst transmission should be terminated, the transmission is terminated by lowering a target signal -to-noise ratio (SIR) by a predetermined amount. By lowering this target SIR, power control bits transmitted from the base station to the wireless unit instruct an extreme decrease in power of the burst transmission and quickly act to terminate the burst transmission.

    Abstract: In a system of communication, a sending node sends a message to a receiving node, which NAKs unsuccessful transmissions. The sending node screens the NAKs to determine if they were sent before the receiver could receive previous transmissions of the same data NAKed. One screening technique is based on an estimated round trip time of a message. Another alternate technique looks a flag in the NAK that synchronizes the sender and the receiver.

    Abstract: A base station assembles a frame including information bits at a vocoding rate for downlink transmission over a traffic channel as channel bits at a channel rate. The base station places at least one rate-indicating bit at a beginning of the frame for indicating the vocoding rate. The mobile station evaluates the downlink transmission with consideration of the vocoding rate indicated by the at least one rate-indicating bit. The mobile station can determine the vocoding rate by decoding the beginning of the frame to permit power control in less than one frame duration from initial receipt of the frame at the mobile station.

    Abstract: The present invention is a method for efficiently utilizing spectrum resources belonging to a wireless communications system in the presence of data channels through a discontinuous data transmission technique. The discontinuous data transmission technique involves the transmission of a flag over a control channel (or some other communication channel) in frame f, wherein the flag would indicate to an intended recipient that a transmitter has a data frame to transmit to the recipient in some future frame f+q. In an embodiment, the transmitter would subsequently transmit the data frame over a data channel (or some other communication channel) in frame f+q if the flag indicated that the data frame was ready to be transmitted. In another embodiment, the transmitter would not transmit the data frame unless the recipient has indicated (via another flag) that the recipient is ready to receive the frame of data from the transmitter.
