Abstract: 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.

Abstract: A wireless data communication system includes a high speed dedicated physical control channel (EU-DPCCH) used with transmissions from a mobile device to support an uplink high speed data channel. In one example the EU-DPCCH has a sub frame structure that is the same as an associated dedicated data channel and a fixed spreading factor. The EU-DPCCH allows communicating control information from the mobile device such as a pilot reference, hybrid automatic repeat request information, and backlog information regarding a buffer of the mobile device.

Abstract: A method is provided to accurately predict the probability of successfully recovering frames of (coded) information received over a wireless link, without having to decode the frame. This method includes receiving a first encoded signal and predicting link errors based on characteristics of the first encoded signal and variations in these characteristics before decoding the first encoded signal.

Abstract: A scheduling strategy utilizes a total call load metric in place of a reverse signal strength indicator metric for managing reverse link resources. In a disclosed example, a load control module (40) measures the reverse signal strength indicator (62) and measures an active call load (64) using known techniques. A relationship between the reverse signal strength indicator, the active cell load, an other cell load component and a jammer component provides the ability to determine the other cell load component and the jammer component. Once the other cell load component has been determined, a total call load based upon the active cell load component and the other cell load component provides a useful metric for allocating reverse link resources between existing users and for determining whether to allow a new user, for example. In a disclosed example, the total call load at a time for scheduled transmission is estimated based upon recently measured values.

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: 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. The method also includes transmitting a message from one of at least the first and second pluralities of messages.

Abstract: The capacity of a reverse link is improved by realizing a scheme to effect sharp changes in pilot channel transmit power (PCTP) and data channel to pilot power ratio (DCPR), coordinated with the start of the data channel transmission. The change in pilot power and data channel to pilot power ratio is also applicable to mobiles that use multiple pilots and/or multiple antennas at the transmitter and/or receiver.

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.

Abstract: A method for reliably transmitting signaling information is provided. One type of signaling information is transmitted over a primary control channel. The signaling information that is to be transmitted over the primary control channel is defined as a set of particular information. Other signaling information are conveyed over a secondary control channel. Prior to transmission, the information to be conveyed over the secondary channel is scrambled in accordance with a particular scrambling procedure that indicates the information that is to be sent over the primary control channel. The scrambling is thus used to encode the information content of the primary control channel into the information of the secondary control channel thereby further protecting the integrity of the information being conveyed over both control channels.

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 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.

Abstract: A method of providing an efficient channel structure for a communication system that uses codes to define its communication channels. Available codes form a code space that is equally divided into M tiers based on load conditions; M is an integer equal to 1 or greater. Information is scheduled to be transmitted during a particular time slot and is assigned to a particular tier. The information is transmitted during the scheduled time slot using all of the codes of the assigned tier.

Abstract: A method is provided to accurately predict the probability of successfully recovering frames of (coded) information received over a wireless link, without having to decode the frame. This method, which consists of three steps, requires only limited information about the received signals and the forward error correction code and retransmission scheme being used. First, the signal to noise ratio (SNR) of each of the received signals is measured, where the average SNR is determined for multiple segments that together constitute the frame. Next, an algorithm is employed that takes these SNR values as inputs and determines the so-called effective SNR. The algorithm translates the measured SNR values using an appropriate convex metric, and subsequently combines the resulting values, thereby factoring in the effects of fading, multi-path, and other signal degradations.

Abstract: Data rate determination is provided in a system where the available power fraction and available Walsh codes in each active leg are dynamically changing over time. This method adapts the rate (modulation and coding) based on the combined resource (power & code space) levels seen at each cell. The method results in maximization of the rate supportable by each cell given their resource constrained situation while meeting the constraints of target packet or frame error rate and orthogonality. Furthermore, improved fast cell selection by the mobile results due to this approach that is based on knowledge of combined resource (power & code space) levels across the cells in the active set.

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 of transmitting or retransmitting a packet in a communication system. The method includes determining a modulation and coding scheme (MCS) to reduce the packet error rate (PER) for transmission, where the MCS is an aggregate of M redundant packet transmissions as a function of at least one of determined past channel conditions and/or allocated resources, determinable current channel conditions and/or allocated resources, future statistical channel conditions and/or allocated resources, and/or a cost function; and transmitting the packets in the communication system according to the MCS.

Abstract: 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.
