摘要： 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.

摘要： The invention provides a method and apparatus for reducing transmission signal power or interference of transmitted communication signals suitable for use in a communication system having a base station and a plurality of user stations that exchange communication signals with the base station. An input node receives channel data for transmission on a plurality of channels to the plurality of user stations, wherein the channel data includes pilot symbol data. A processor determines symbol positions in which each of the plurality of user stations expect to find pilot symbols. A transmitter transmits to the plurality of user stations pilot symbols only in symbol positions that the plurality of user stations expect to find pilot symbols, and failing to transmit pilot symbols in other symbol positions.

摘要： A method for coherent estimation of the traffic-to-pilot energy ratio is presented. A received preamble is decoded (20), and then re-encoded (22). The received preamble is then multiplied by the re-encoded preamble (23). The results are summmed (24), squared (26), and then divided by a pilot energy value (28). In another method, a message (41) carrying energy information can be inserted between a subpacket preamble (40) and a subpacket (42).

摘要： Techniques for puncturing symbols in a communications system. S symbols are received for a frame having a capacity of N symbols, with S being greater than N. P symbols need to be punctured so that remaining symbols fit into the frame. A number of puncture distances, D1 through DN, are computed based on S and P. A particular number of symbol punctures is determined for each computed puncture distance. P1 through PN symbol punctures are then performed at the distances of D1 through DN, respectively. For a more even distribution of the symbol punctures, each of the distances D1 through DN can be selected to be greater than or equal to a minimum puncture distance Dmin defined as Dmin = [S/P], where [] denotes a floor operator. The symbol punctures at each computed distance can be performed together or distributed with symbol punctures at other distances.

摘要： 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 transmitted 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.

摘要： A method (18) for scheduling packet data transmissions in a wireless communication system (10) 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, 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. The PF values allow the base station (12) to schedule active mobile units (16) having pending data. The scheduling produces an approximately equal share of the allocated transmission time to the multiple mobile stations (16).
