    Abstract: Method and apparatus for congestion control in a wireless communication system. Individual target data rate values are assigned individual access terminals. The individual data rates of the access terminals are adjusted to achieve the corresponding individual target data rate values (208, 218). If the target values are not achieved within a predetermined number of iterations, the individual data rate is adjusted. In one embodiment, the status of a congestion bit indicates the type of adjustment, such as increas e or decrease (204), wherein the status of the congestion bit is determined by comparing a congestion parameter to a predetermined threshold. One embodimen t implements an outerloop threshold having a margin with respect to the desire d congestion metric threshold. According to one embodiment, a congestion indicator includes multiple bits, wherein at least one bit instructs the mobile station to use target values or else to adjust without regard to a target value (210, 216).

    Abstract: A method for limiting peak transmit power in a CDMA communication system by transmitting a first communication signal having a first high transmit power region, and transmitting a second communication signal having a second high transmit power region. A first and a second communication signal are time offset to prevent the first and second high transmit power regions from occurring simultaneously. Time shifting only a portion of the first and second communication signals is also taught. The first and second communication signals can also include respective first and second low transmit power regions. The time offset can be selected to align one of the first and second high transmit power regions with one of the first and second low transmit power regions. The total transmit power signal can be determined and the time offset can be selected to minimize a peak level of the total transmit power signal. The communication signals are separated into a plurality of portions and portions of the first and second communication signals are time offset to re-order the sequence of transmission of the plurality of portions.
