Abstract: Method and apparatus for providing link quality feedback to a transmitter (32,34). In one embodiment, a periodic link quality message is transmitted on a gated channel, while continuous differential indicators are transmitted. Between quality messages, the differential indicators track the quality of the link. In one embodiment, a remote station includes a differential analyzer (212) to determine the change in successive channel quality measurements. The quality metric and the differential indicator are used for providing power control commands and rate control commands to teh base station. The quality metric and the differential indicator are transmitted at two different frequencies.

Abstract: A method and apparatus for controlling transmit power levels of a plurality of different data streams (120, 120a, 122, 122a, 124, 124a) transmitted from at least one base station to a mobile station in a mobile radio communication system. The first and second data streams are trasmitted from the base station and received at the mobile station. A stream of power control commands is formed at the mobile station in accordance with either the first or second received data stream. A power control signal is formed at the mobile station from the first stream of power control commands and transmitted to the base station. A received stream of power control commands is formed from the received power control signal at the base station, and the transmit power levels of the first and second data streams from the base station are controlled in accordance with the received stream of power control commands.

Abstract: A method (18) for scheduling packet data transmissions in a wireless communication system wherein a per-user Priority Function (PF) (24) is based on a channel condition indicated by a Rate Request Indicator (RRI). The method also considers fairness criteria dictated by predetermined Quality of Service (QOS) requirements. In one embodiment, the rate request indicator is a Data Rate Request (DRR). In another embodiment, the rate request indicator is Carrier-to-Interference (C/I) information. In the exemplary embodiment, the base station calculates a Priority Function (PF) for the multiple mobile users. Each PF is a function of the rate request indicator and the projected throughput of a given mobile user. In one embodiment, the predicted throughput is calculated by T′=(T′)α.
