    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: In the method, an average user throughout over all active users is computed, and each user's user perceived throughput is compared against the computed average throughout. Based on the comparison, the scheduling of the plurality of users is prioritized. In an embodiment, a priority adjustment factor is applied to each user to prioritize the scheduling of users to receive a data transmission. The priority adjustment factor is determined based in part on an update function. The update function is proportional to a calculated difference between each user's user perceived throughput and the average user throughput. Based on the sign of the update function, the priority adjustment factor is either incremented or decremented, and hence, prioritization of users is ordered. The output of the scheduler is user identifying information that informs the base station to transmit data in a current time slot to the identified user determined as the highest priority user by the scheduling method.

    摘要: The present invention provides a method and an apparatus for controlling a radio frequency resource between a first and a second wireless unit and a base station to provide overload control of the radio frequency resource based on an estimate thereof. For example, when feedback information is unavailable for the radio frequency resource at the base station. The method includes estimating the radio frequency resource used by the first and second wireless units in a wireless data network. The method further includes providing an overload control at the base station based on the estimated radio frequency resource. Based on this estimated radio frequency resource, a command may be issued by the base station on a reverse link. For example, a rise over thermal resource may be estimated to issue a rate control command to a wireless unit. By providing a desired timely rate control command on the reverse link, the base station may control a data rate of the wireless unit, maximizing throughput of the reverse link. In this way, a base station may control a rise over thermal resource metric to relieve an overload condition at the base station in a relatively high-speed wireless data network.

    摘要: The method provides for establishing a communication session in a hierarchical communication system between a source party and at least one destination party. Hierarchical communication systems generally have communication nodes at different levels of hierarchy. In one embodiment, connection information for the communication session is stored if establishing the communication session is blocked at a node as a result of a blocking condition at the blocking node. Establishment of the communication session is initiated based on the stored connection information if the blocking condition no longer exists at the blocking node.
