Abstract: A method of scheduling a plurality of subscriber equipment based on sets of channel conditions and calculated power allocations for downlink channels of an air interface of a wireless communication system to satisfy a desired system requirement. A set of subscriber requesting access to the communication system or being provided access to the communication are selected by a scheduler based on their channel conditions and power allocation calculation. The scheduler then schedules the selected set of subscribers to achieve the desired system requirement whereby the subscribers simultaneously receive information from a multiple of antennas which are typically located at a base station.

Abstract: A method of providing a plurality of schedulers for independently scheduling multiple subscribers to increase the capacity and/or throughput of an HDR wireless communication system. Each scheduler is associated with base station equipment and an antenna that receive channel conditions on which the scheduling of subscribers are based.

Abstract: A wireless data communication system simultaneously transmits data signals from more than one antenna with a deterministic, time-dependent phase difference between the signals. In one example, more than one antenna transmits the same data signal with a phase difference between the transmitted signals. In another example multiple users' data signals are simultaneously transmitted using a corresponding plurality of beams that each use at least two transmitting antennas. Transmissions to multiple users on a shared packet data channel can be scheduled at the same time. In one example, the phase difference is periodic and the beams are orthogonal to maximize system throughput even when one or more users is stationary or slowly moving.

Abstract: 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.

Abstract: A transport channel multiplexing system provides improved use of wireless resources in a shared data channel system. For example, the transport channel system reduces the amount of transport format information required for using a shared data channel, such as the actual number of packet data units in a transport channel of the shared data channel. Additionally, by scheduling or multiplexing coded sub-blocks from one or more transport channels over the shared data channel, the transport channel multiplexing system can provide improved integration with other important features, such as incremental redundancy, fast adaptation to channel conditions and transport channel dependent quality of service (QOS) control, to provide improved system performance.

Abstract: A rate feedback and adaptation scheme or system uses a rate of rate feedback asymmetrical with the rate of data rate adaptation. In particular, the rate adaptation system provides a rate of rate feedback slower than the rate of rate adaptation. Thus, by allowing the base station to change the data rate more frequently than the individual wireless units reports the rate information, the rate adaptation system can provide improved flexibility and more efficient use of wireless resources while reducing the processing and transmission overhead required to report the rate information. For example, every 3 slots, a wireless unit can calculate and report a rate for the wireless unit to use on a shared channel to send data. The base station receives the rates from the wireless units seeking to send data over the shared channel and selects a wireless unit to use the shared channel.

Abstract: An uplink and downlink channel structure supports a shared downlink data channel. The new structure accommodates advanced physical and Medium Access Control (MAC) layer techniques, such as incremental redundancy (IR), fast adaptation to channel conditions, and multiple input multiple output (MIMO) antenna configuration. The proposed changes are intended to lead to a downlink structure that achieves higher spectral efficiency for the packet oriented services over then shared downlink channel. Additionally, the new structure uses the base station transmit power information and of the channelization (OVSF) code space more efficiently.

Abstract: A communication system's transmit configuration is reconfigured based on mobile station associated conditions such as the capability of the mobile receiver, carrier to interference or signal to noise ratios, and the degree of mobility associated with the mobile station. As a result, the transmit configuration is optimized for the conditions associated with a particular mobile receiver. In one embodiment, the transmit configuration may be selected to operate in configurations such as a single transmit antenna configuration, a space time spreading configuration, a selective transmit diversity, and a multi-output and multi-input configuration.

Abstract: Pilot signals transmitted by different antennas in a wireless communication system using multiple transmit antennas are distinguished using different codes. In one embodiment, each of two antennas simultaneously transmit a time slot's worth of data while time division multiplexing a pilot signal with the data. The pilot signal from the first antenna is encoded with a first code such as a Walsh code and the pilot signal from the second antenna is encoded with a different code such as a different Walsh code. The different codes enable a receiver to distinguish the pilot signals when they are received to enable coherent detection of signals transmitted by both of the antennas.

Abstract: 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.

Abstract: A method for allocating data rate to a stream of information to be transmitted over a communication channel of a communication system is provided. Modified union bounds are used to determine the channel characteristic experienced by each of the streams to select their respective data rates from an MCS that can be handled by the communication channel of the communication system.

Abstract: A method for increasing the capacity of a communication network by assigning subscribers of the communication network to individual antennas of an antenna array and allowing the antenna array to convey information to the assigned subscribers under the control of a scheduling algorithm. Antennas—under the control of the scheduling algorithm—in the antenna array are thus able to convey information to different subscribers at different times. The scheduling algorithm determines when to convey information to an assigned subscriber based on channel condition information it receives from the subscribers. The scheduling algorithm also uses the channel condition information to assign certain subscribers to certain antennas.
