  • Publication number: 20080101257
    Abstract: Apparatus, and an associated method, for reporting QoS information associated with a reverse link communication service effectuated in a radio communication system, such as a CDMA2000 cellular communication system. The mobile station includes a service quality level selector that selects a selected service quality level, such as a communication rate, at which the communication service is to be effectuated. The mobile station further selectably includes a message generator that generates a service quality indication message. A detector detects the scheduling architecture of a network part of the communication system with which the mobile station communicates. And, information contained in the message generated by the message generator is dependent, in part, upon the scheduling architecture.

  • Publication number: 20080077838
    Abstract: Apparatus, and an associated method, that reduces the occurrence of generation of redundant requests for retransmission of packet-formatted data, formatted at a physical layer and at a higher-logical layer, such as at an RLP layer. An estimate of an appropriate delay period is formed. The estimate is responsive to communication conditions in the communication system. When a data packet appears to have been inadequately delivered to the RLP logical layer, a DELAY_DETECTION_WINDOW timer is caused to time out the delay period estimated by the estimator. The request for retransmission, generated at the RLP layer, is permitted, upon expiration of the timer if the data packet has not yet been successfully delivered to the RLP layer and the transmitter has not given up the data packet delivery.

  • Publication number: 20070064692
    Abstract: An approach is provided for addressing in a multiple carrier communication system. In one embodiment, a group index is assigned to a group of terminals of a communication network. The group index permits sharing of addressing indices supported by the communication network for transmission of data to the group of terminals. In another embodiment, a plurality of terminals is classified using preamble indices corresponding to the terminals into one or more classes. A multi-user packet, which utilizes the preamble indices to activate only a class of the terminals for processing the multi-user packet, is generated.

  • Publication number: 20060187870
    Abstract: A method is provided for facilitating efficient usage of radio capacity in a radio communication system including a communication station operable to receive, over a plurality of subchannels of the radio communication system. In this regard, the packet-formatted data has an overall sequence, and is divided into a plurality of portions receivable by the communication station over respective subchannels, where each portion has a respective link sequence. The method includes detecting missing packet-formatted data at the communication station based upon the overall sequence or at least one of the link sequences. Then, when the missing packet-formatted data is detected based upon the overall sequence, a time period is timed, and when the communication station fails to receive the missing packet-formatted data before the step of timing times out, retransmission of the missing packet-formatted data is requested.

  • Patent number: 7046642
    Abstract: A method and apparatus for dynamically configuring parameters of the radio link protocol layer in a telecommunications system. The method and apparatus allows dynamic configuration of the radio link protocol layer in order to optimize parameters for use with a particular data service. In an embodiment of the invention, radio link protocol control frames used for connection initialization include RLP parameter data. The RLP parameter data is exchanged between two communicating transceiving devices during connection initialization, and is used in each transceiving device to configure subsequently transmitted RLP data frames and transmit retransmission requests accordingly.

  • Publication number: 20050169171
    Abstract: An approach is provided for supporting end-to-end Quality of Service (QoS) control. A QoS profile identifier is generated that maps to a QoS parameter. The identifier is transmitted over the radio communication system to an end station, wherein the end station determines the QoS parameter based on the received identifier. The approach also provides an alert mechanism in which the end station transmits an alert message upon detecting a deviation from the QoS parameter.

  • Publication number: 20050111358
    Abstract: Apparatus, and an associated method, for generating a TVMAR (traffic volume measurement and reporting) report, or other appropriate report, to facilitate packet scheduling in a packet-based communication system. A signal is generated at a network part of a radio communication system indicative of parameters that the mobile station is to include in the TVMAR report, subsequently to be generated by the mobile station. The signal is generated by a signal generator and sent to the mobile station to be detected thereat by a detector. The communication indicia is measured by a measurer and the measured values of the selected parameters are formed into a TVMAR report and returned to the network part.

  • Patent number: RE39164
    Abstract: A method and system for transmitting packet data over a cellular telecommunications network is presented. A novel medium access control (MAC) logical layer is implemented between a service option layer and multiplex sublayer. The MAC layer handles the multiple accesses of packet users over selected dedicated traffic channels. The MAC layer provides a multiple access control function for packet data users only. Users requiring only circuit switched services (voice calls) are not serviced through the MAC layer multiple access control function. If a user has simultaneous circuit switched and packet data services operating, the MAC layer multiple access control function handles the packet data services, while the circuit switched services are handled simultaneously by bypassing the MAC layer multiple access control function.
