摘要： A method for conveying signaling information of a communication system that uses MIMO antenna systems. To enable a relatively larger amount of information to be conveyed over the communication system and thus exploit the use of the MIMO antenna system, forward link signaling channels are provided where such channels contain swapping information that allow the communication system to retransmit traffic information using any one of the antenna elements of a MIMO system. The forward link signaling channels also contain channel assignment information that indicate which particular groups of channels are available for use by particular users of the communication system. To further accommodate for the relatively larger amount of information being conveyed over the communication system, the format of the reverse link signaling information is modified using any one or any combination of the following three mechanisms: (1) reverse signaling link information is time division multiplexed; (2) the reverse link information is modulated at relatively higher order modulation; (3) additional channels are provided for the reverse link information.

摘要： Disclosed is a method of integrating voice and data services onto a same frequency channel using available transmit power information to determine data rates, wherein the available transmit power information indicates an amount of transmit power available for future data transmissions over one or more data channels. In a “distributed” embodiment, a transmitter or base station transmits, via a forward link, an available power message to a receiver or mobile-telephone indicating an amount of available transmit power at some future time t+z. The mobile-telephone performs signal-to-interference measurements corresponding to the received forward link and received interference, and uses such signal-to-interference measurements and the available power message to determine a data rate that can be supported by the mobile-telephone. Preferably, the determined data rate corresponds to a maximum data rate at which a minimum level of quality of service can be achieved at the mobile-telephone. In a “centralized” embodiment, the mobile-telephone transmits the signal-to-interference measurements to the base station, and the base station determines the data rate based on the available transmit power at future time t+z.

摘要： Efficient data communication in wireless communication system is provided by using centralized control of data communications, such as packet switched services, over the uplink channel (mobile station (MS) to base station (BS)). A multiple access protocol is used where packet data mobile stations make requests for uplink channel resources. The request messages transmitted by the MSs inform the BS of service parameters. Examples of such service parameters are available transmit power at the MS, the amount of data to transmit and Quality of Service (QoS). The BS then processes the received request messages and performs interference management calculations to determine the portion of the BS's receive power budget that can be allocated to the data user requesting service. These calculations are used to control the amount of interference seen at the base station, to assign a data rate to the user and to aid scheduling algorithms in computing service order priorities. Any scheduling algorithm may be used; for example, scheduling may be based on the amount of data to be transmitted, the age of the data or the service priority associated with the mobile station. The interference control is used to prevent the occurrence of catastrophic levels of interference while maximizing the utilization of resources on the uplink.

摘要： A method and apparatus are provided for dynamically controlling a high speed wireless communication system to optimize utilization of system resources and increase system throughput. The invention operates to determine an allocation of wireless transmission resources to each user application served by the wireless system in a manner to optimize transmission resources while meeting required QoS criteria for the served user application. After all user applications have been provided a transmission resource allocation in this manner, the total transmission resources so allocated are determined and compared with a ceiling transmission resource level for the wireless system. A portion of the difference between the ceiling and currently allocated transmission resource levels is then made available, according to the invention, to the served user applications in proportion to the initial allocation provided each user application. An admission control methodology is also provided which is implemented in a cooperative relationship with the further resource allocation process of the invention.
