摘要： The present invention provides a method and an apparatus for controlling transmission power of a wireless unit. The method includes providing a power control in a reverse link to a network that transmits data on a traffic channel in a bursty manner based on a performance metric of a channel with continuous transmission of other data than on the traffic channel. To provide a power control in a reverse link of a spread-spectrum wireless data network a method and an apparatus are provided for combining performance of a quality of service from at least one of a first quality feedback channel and a second quality feedback channel with that of a pilot channel and providing an outer-loop power control in said reverse link for a wireless communication on a traffic channel based on said combined performance of the quality of service to control transmission power of a wireless unit. A quality of service metric may be associated with one or more channels of the reverse link to determine performance of such a channel when transmission of data on a traffic channel is bursty in nature. Using a performance metric, such as a quality of service metric of a pilot channel, a power control in the reverse link may be provided when data is not transmitted on the traffic channel, e.g., in a bursty traffic channel to control transmission power of a wireless unit. In this manner, the transmission power of the wireless unit may be controlled based on an outer-loop power control that provides a continuous control for a non-continuous transmission.

摘要： Outer loop power control for a traffic channel includes using at least one output from another channel to determine an appropriate control threshold such as a signal-to-noise ratio when selected channel conditions exist. One example traffic channel condition comprises having insufficient data transmission to provide a direct measurement of packet error rate. Another example traffic channel condition used to determine when to use the other channel output is a transmission mode on the traffic channel. An example output used for setting the control threshold is a chip energy to noise ratio of a pilot channel associated with the traffic channel.

摘要： Data communication includes an estimate of packet error rate that is useful, for example, when there is insufficient data transmission to provide a direct measurement of packet error rate. At least one pilot channel output provides a basis to determine an estimated packet error rate. One example includes using a pilot channel ratio of an energy-per-chip to a noise spectrum density. Another example includes using a pilot symbol error rate from the pilot channel as the basis for determining the traffic channel packet error rate.
