Abstract: A method of operating a Power Line Communications (PLC) network including a plurality of nodes having wirelines extending therebetween for propagating PLC signals between said nodes over said wirelines. The method includes coupling to a set of nodes of the PLC network respective partitioning filters, which can be activated for countering propagation of the PLC signals through the nodes to which said partitioning filters are coupled. The method also includes selectively activating filters chosen from among said partitioning filters, so that said PLC network is partitioned into a plurality of sub-networks with the propagation of PLC signals between the various sub-networks countered by the activated partitioning filters.

Abstract: A transmitting peer transmits radio blocks over a radio interface from within a transmit window. A receiving peer receives the radio blocks within a receive window, and in case of a not correctly received radio block, sending back a NACK (Not Acknowledged) signaling message to inform the transmitting peer of reception failure. Upon reception of the NACK signaling message, the transmitting peer retransmits, until expiration of the transmit window, the not correctly received RLC/MAC radio block. The radio blocks are re-assembling in sequence at the receiving peer. Each radio block is considered as being permanently lost if not correctly received within the receive window. All correctly received radio blocks are delivered to a higher protocol layer. The network transmits a notification message to both the transmitting peer and the receiving peer to select a size of the transmit and receive windows inside a range of predetermined values including values less than 64 radio blocks.

Abstract: Real-time media or multimedia services in 3GPP GSM/EDGE-compliant mobile radio networks call for reducing the actual latency of transmissions. Resources are assigned by the network to set up or reconfigure a TBF associated to the uplink/downlink transmission of radio blocks from/to an MS. A 5-bit “Coding” field is configured in the header of the involved RLC/MAC messages to select the transmitting/receiving window size. An additional signaling bit, also called scaling bit, is asserted/negated according to two opportunities offered by the new MAC protocol to properly select the window size. Thanks to the introduction of the scaling bit a subdivision of the time windows for type of services is made possible. Non real-time services, e.g. file transfer, all of standard window sizes for MSs with multistat capability, as reported in 3GPP TS 44.060, V7.3.0 (2006 February), Release 7, subclause 9.1.9, for EGPRS TBFs. Delay-sensitive services, e.g.

Abstract: A radio link connecting a mobile terminal to a communication network, is adapted by varying the Modulation and Coding scheme over the radio link as a function of both a signal-to-disturbance ratio (e.g. the Carrier to Interference-plus-Noise Ratio or CINR) measured over the link and at least one of a mobility profile of the mobile terminal and a Quality of Service class associated with the link.

Abstract: An end to end fast signalling procedure is disclosed in order to improve standard RTP/RTCP transport protocols for the support of streaming services within any kind of wireless and/or mobile networks, in particular for the introduction within GSM-GPRS. The streaming flow is expected to be sent from an Internet Service Provider (ISP) to Mobile Stations (MS). During fast signalling procedure, RTCP feedback messages are sent at a rate higher then the one expected in standard RTCP protocol. Fast signalling messages are made by upgraded Receiver Reports (FRR) intended to make the end to end QoS control mechanism able to react quickly to sudden changes in the available bandwidth that can occur at the radio interface.

Abstract: The invention discloses a method to perform downlink Power Control in packet switching cellular systems with dynamic allocation of the RF channel, such as GPRS/EGPRS. The performances concern a scenario in which a radio block transmitted from the Base Station (BTS) on a downlink channel has to be received from at least two MSs simultaneously, a first MS being the addressee of the data/control packet on the downlink TBF while the second MS being the addressee of the Uplink State Flag (USF) for scheduling transmission of the next data/control packet from an uplink TBF to an uplink shared channel. First MS transmits to the BTS a first measurement report including measures of BCCH level and interference level on all the timeslots, while the second MS transmits a NC report including measures of BCCH level only, that because detailed interference measure on the downlink channel are prevented due the absence of a concurrent downlink TBF.
