Abstract: A buffer status reporting scheme for a terminal (10) wishing to transmit data simultaneously in multiple RATs of a wireless communication network, which enables the co-ordination of multiple base stations (12, 14) of different RATs (e.g. LTE eNB, UMTS base station, WiFi access point, etc.) with the assistance of the terminal (10) in order to achieve efficient radio resource scheduling for multi-RAT multi-flow aggregation in uplink. A radio bearer is configured for multi-RAT multi-flow aggregation by the network, and multiple logical channel IDs are assigned to this RB that may be associated with different RATs. Logical channels associated with a certain RAT (or a given set of RATs) may be grouped into one logical channel group for radio resource scheduling reason. The terminal (10) performs buffer status reporting, according to the configuration, on all involved RATs and sends reports/indications to one or more involved base stations (12.14).

Abstract: A gateway modem server device for a home LAN. The modem server includes a first transceiver that utilizes DMT modulation methods for communication over the local LAN, and a second transceiver for communication with the access infrastructure that utilizes POTS telephone services. The LAN devices connected to the LAN access the modem server via LAN adapter devices. The adapter devices are internal or external to the LAN devices and provide a transceiver and protocol stacks for the LAN devices to communicate with each other. The physical layer of the transceivers includes transmitter having a DMT modulator and demodulator that is dynamically configurable with respect to data rate and spectrum usage. The devices communicate with the modem server and the modem server communicates to the POTS service provider over the same medium.

Abstract: A new concept of soft quality-of-service (soft-QoS) is developed that bridges the gap between the efficient provision of network-level QoS and the requirements of multimedia applications. Soft-QoS is defined by a satisfaction index (a number that rates users' perceptual quality) and a softness profile (a function that captures the robustness of multimedia applications to network congestion). Another aspect of this invention is a bandwidth allocation scheme for multimedia applications with soft-QoS requirements is presented. The implementation of the bandwidth allocation scheme on a network element realizes a soft-QoS controller. The controller uses the connections' softness profiles to compute a bandwidth allocation that maximizes the minimum satisfaction index of active connections.

Abstract: A method and apparatus are provided for selecting a digital channel from a composite digital signal which is made up of a plurality of digital channels. The method is accomplished by assigning two frequency bands of a plurality of frequency bands to each of the plurality of digital channels, wherein the two frequency bands overlap. A filtering process is accomplished by selecting a filter, from a group of filters, the selected filter corresponding to one of the frequency bands. The selected filter is then applied to the composite digital signal.
