    Abstract: Methods and systems are provided for simple cable phone and internet (SCPI) device that may be coupled with a cable modem (CM) and one or more SCPI head ends, e.g., via an SCPI access point. The CM may be capable of communicating a first modulated signal with a cable modem termination system (CMTS), via the SCPI device. The SCPI device may be capable of combining a second modulated signal to the first modulated signal thereby generating a combined signal. The SCPI device may be capable of sending the combined signal comprising the first modulated signal and the second modulated signal to the CMTS and an SCPI head end. The SCPI head end may be capable of processing the combined signal and extract information and/or data associated with a service. The SCPI head end may deliver the extracted information and/or data to an appropriate gateway.

    Abstract: It is presented a method, performed in a network node, for enabling selection of modulation mode for a user equipment, UE. The method comprises: determining whether to provide higher order modulation, HOM, mode support for the UE; when HOM mode support is to be provided, selecting at least one HOM table for the UE; and when HOM mode support is not to be provided, selecting at least one non-HOM table for the UE.

    Abstract: Embodiments of full-duplex systems with reconfigurable antennas are described. In one embodiment, a full-duplex reconfigurable antenna transceiver includes a transmit chain, a receive chain, and a reconfigurable antenna having a plurality of reconfigurable modes. The transceiver may also include an antenna controller configured to set a mode of the reconfigurable antenna. According to other aspects, the transceiver may also include a signal processor configured to transmit a set of training symbols during a training interval. The antenna controller may be further configured to select a respective mode of the reconfigurable antenna for each training symbol in the set of training symbols. Additionally, the antenna controller may be configured to calculate a received Signal-of-Interest to Interferer Ratio (SIR) for each training symbol of the set of training symbols. In this context, a full-duplex system utilizing a reconfigurable antenna may achieve significant rate improvement compared to half-duplex systems.
