    Abstract: Operational and environmental efficiency in virtual radio access networks (VRANs) can be improved by offloading data traffic and/or control signaling between physical transmit points (TPs) of a virtual TP. This may allow one or more physical TPs of the virtual TP to be muted in the downlink or uplink direction, thereby reducing energy consumption. The offloading may be performed during relatively short time-intervals such that physical TP are muted for one or more transmission time intervals (TTIs) before being re-activated. The offloading may also be implemented over longer time-intervals in accordance with a traffic engineering (TE) policy. Further it is possible to re-activate a de-activated downlink transmitter of physical TP by monitoring wireless signals via an activated receiver of the physical TP.

    Abstract: Methods and devices are provided for communicating data in a wireless channel. In one example, a method includes adapting the transmission time interval (TTI) length of transport container for transmitting data in accordance with a criteria. The criteria may include (but is not limited to) a latency requirement of the data, a buffer size associated with the data, a mobility characteristic of a device that will receive the data. The TTI lengths may be manipulated for a variety of reasons, such as for reducing overhead, satisfy quality of service (QoS) requirements, maximize network throughput, etc. In some embodiments, TTIs having different TTI lengths may be carried in a common radio frame. In other embodiments, the wireless channel may partitioned into multiple bands each of which carrying (exclusively or otherwise) TTIs having a certain TTI length.

    Abstract: An embodiment method includes identifying a plurality of VTP configurations representing allocations of TPs among a plurality of VTPs each having at least one TP. Potential serving VTPs are then identified for a selected UE in a plurality of UEs according to at least one UE centric criterion. The potential serving VTPs are selected for each of the plurality of VTP configurations. A UE measurement set is then scheduled for the potential serving VTPs for a scheduled channel resource according to measurement parameters. The method further includes selecting a serving VTP configuration from the plurality of VTP configurations according to UE measurement feedback from the selected UE.

    Abstract: A method embodiment includes defining, by a network controller, one or more operation modes for a radio node in a network. The one or more operation modes includes a hyper transceiver mode, where the hyper transceiver mode configures a virtual transmission point to cooperatively communicate with a virtual reception point in accordance with neighborhood relations of a target radio node. The method further includes selecting one of the one or more operation modes for the radio node and signaling a selected operation mode to the radio node.

    Abstract: System and method embodiments are provided to support network communications with groups of UEs. The embodiments include a two-level group-based hybrid-automatic repeat request (HARQ) mechanism and acknowledgement (ACK)/negative ACK (NACK) feedback. An embodiment method includes receiving, at a UE within a virtual multi-point (ViMP) comprising UEs, a data packet for a target UE (TUE) that is broadcasted from a base station (BS) to the ViMP node, decode the data packet, and upon successfully decoding the data packet, broadcasting the data packet to the UEs within the ViMP node until a timer pre-established by the BS expires or an ACK message is received from the TUE or the ViMP node. In an embodiment, broadcasted data received in the ViMP node is re-broadcasted upon receiving a negative acknowledgment (NACK) message from the TUE, a beacon UE, or any of the UEs within the ViMP node.

    Abstract: Different filtered-orthogonal frequency division multiplexing (f-OFDM) frame formats may be used to achieve the spectrum flexibility. F-OFDM waveforms are generated by applying a pulse shaping digital filter to an orthogonal frequency division multiplexed (OFDM) signal. Different frame formats may be used to carry different traffic types as well as to adapt to characteristics of the channel, transmitter, receiver, or serving cell. The different frame formats may utilize different sub-carrier (SC) spacings and/or cyclic prefix (CP) lengths. In some embodiments, the different frame formats also utilize different symbol durations and/or transmission time interval (TTI) lengths.
