A device () for dynamically selecting a wireless communication mode for wirelessly communicating information to at least two wireless communication devices () includes a packet data comparator () adapted to compare data packets in multiple data streams, each stream designated for transmission to a different one of multiple destination devices and also to identify at least two of the packets having identical information in at least a portion of the packets. The device () also includes an output () for sending the at least a portion of the packets having the identified identical information to the at least two wireless communication devices in the multicast mode, and also for sending a remainder of the data streams to the at least two wireless communication devices in a unicast mode.

Method and system for utilizing commonality in data streams

A method is for selecting a coding scheme for use in a wireless packet data communication system. The coding scheme is one of a set of coding schemes that are useable on an uplink or downlink channel. States of support of a mobile station corresponding to the set of coding schemes are set to one of a set of values including supported, unsupported, and unknown support. A portion of an uplink or downlink data transfer for the mobile station is transmitted using a first coding scheme. The state of support of the mobile station for the first coding scheme is set to one of supported and unsupported based on whether the data transfer is received successfully. A quality measurement is performed during the transfer. A second coding scheme is then selected based upon the quality measurement and the set of states of support of the mobile station.

In the present technique of a data transmission management, responsive to a reselection during a data transmission, a determination () is made as to whether remaining untransmitted data blocks of the data transmission can be sent within an allowed transmission time. If so, the remaining untransmitted data blocks are transmitted () to complete the data transmission. If, however, the remaining untransmitted data blocks cannot be transmitted within the allowed transmission time, the communication link is terminated () to stop the downlink data transmission with a serving station.

Methods for managing data transmissions between a mobile station and a serving station

Communication services are scheduled for mobile stations () within a communication network () based upon characteristics of communication links () associated with each of the mobile stations (). A group of mobile stations is formed based upon the respective characteristics, and communication services are scheduled for the group.

Method and apparatus for scheduling communication services

To address the need for a communication infrastructure and method to speed uplink data setup, the present invention provides for the assignment of uplink packet data resources by basestation transceiver systems (BTSs) without the need to communicate with any packet control unit (PCUs) first. The present invention accomplishes this by reserving packet data resources before they are needed or requested and providing them to BTSs for assignment. Thus, BTS-PCU communication occurs in the period before an uplink connection is needed and after uplink data is established, effectively eliminating the BTS-PCU delay from uplink data setup. Moreover, the present invention provides for the transmission of transmit allowance messages before an uplink request is made by the communication unit, further reducing uplink data setup time.

Communication infrastructure and method to speed uplink data setup

The invention provides a method for determining coding scheme adaptation capability of a mobile station. A packet uplink acknowledgement is sent to the mobile station and a data packet including a coding scheme indicator is received. A determination may be made on whether a coding scheme associated with the mobile station is adaptable and the coding scheme is modified based on the determination.

Method for determining mobile station coding scheme adaptation capability

A method for transitioning from a lower channel coding scheme to a higher channel coding scheme in a communication network providing transmission of data encoded using one of a plurality of channel coding schemes, the transmission occurring between the communication network and a number of mobile stations via a corresponding number of radio links, the communication network having at least one base transceiver station operatively coupled to a packet control unit. The method includes applying the higher channel coding scheme to a portion of data transmitted between the communication network and the mobile station, and, after a predetermined time period, noting a data block error rate of the portion of data. The method further includes directing application of the higher channel coding scheme to all future data transmitted if the data block error rate indicates an equivalent or higher data throughput of the portion of data.

Apparatus and methods for a coding scheme selection

A PCI computer system includes component boards ( ) adjacent to and coupled to a PCI bus ( ), a controller board ( ) coupled to the PCI bus, a transition module ( ) coupled to the PCI bus, a switching matrix ( ) coupled to the transition module, and an I/O module ( ) coupled to the component boards and the controller board via the switching matrix, the transition module, and the PCI bus. A method of operating the PCI computer system includes transmitting a first signal from one of the component boards, transmitting a second signal from the I/O module, transmitting a third signal from the controller board in response to the first and second signals to configure the switching matrix to make the pin-out configuration of the one of the component boards compatible with the I/O module, and transmitting a first set of data between the component board and the I/O module.

The method includes receiving (,) at the base station a handover indication associated with a first mobile communication unit. Based on the handover indication, a desired handover power level for the first mobile communication unit is determined (,). Based on the desired handover power level, a communication link is established with the first mobile communication unit at an actual power level. A difference between the desired handover power level and the actual power level is calculated (,), and based on the difference, a transmit power of the base station is determined.
