The present invention provides a method of providing rate tiers in a wireless communication system. Embodiments of the method include forming, at a network element in the wireless communication system, a statistical representation of resource usage for a user in the wireless communication system as a function of location and/or time using measurements of the user's resource usage at a plurality of locations. Embodiments of the method also include defining, at the network element, a plurality of rate tiers based on the statistical representation. Each rate tier indicates a rate for a different level of resource usage offered to the user.

A method of allocating resources for transmitting content from a network element in a communications network to one or more mobile devices each in communication with the network element may include receiving, at the network element, characteristic information corresponding to each of the one or more mobile devices; and generating one or more adaptive guaranteed bit rate (AGBR) values at the network element corresponding to each of the one or more mobile devices, respectively. The AGBR values may be GBR values generated for each of the one or more mobile devices based on the corresponding characteristic information. A first scheduling algorithm may be executed at the network element based on the one or more AGBR values; and resources may be allocated to the one or more mobile devices based on an output of the scheduling algorithm.

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.

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.

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.

An apparatus and a method for managing resources for efficient packet data transmission. More specifically, there is provided a method for allocating transmission resources in a base station comprising determining a largest supportable packet size for a highest priority user, wherein the determination is based at least partially on the available modulation types, a total number of codes available for packet transmission, a total amount of available transmission power available for packet transmission, and frame durations supported by a base station.
摘要:
A method of scheduling data communication over an uplink. The method enables two or more users seeking to transmit data over the uplink to be scheduled in response to their path loss. The user having the most attractive determined path loss among the two or more users seeking to transmit data over the uplink us scheduled first. Thereafter, the next user having the next most attractive path loss among the remaining users may be subsequently scheduled if the total noise rise leftover is greater than zero. This process repeats so long as or until the total noise rise leftover is about zero.

The present invention provides a method for encoding messages. The method includes identifying at least a first plurality of messages indicative of a corresponding first plurality of data transmission rates and a second plurality of messages indicative of a corresponding second plurality of data transmission rates based on a prior transmitted message, where the first and second pluralities of messages are unequal.
