Abstract: A device for power efficient networking may include a processor circuit configured to identify a time to enter a low power state. The processor circuit may be further configured to transmit, prior to the identified time, transmission parameters to a network coordinator device for a network of devices, the transmission parameters being associated with a transmission from at least one of the devices to the device. The processor circuit may be further configured to enter the low power state at the identified time. The processor circuit may be further configured to, upon exiting the low power state, receive the transmission from at least one of the devices based at least in part on the transmission parameters. The processor circuit may be further configured to receive the transmission without participating in a node admission process after exiting the low power state.

Abstract: A communication device is configured to support communications with other devices using a physical layer (PHY)/MAC interface (PMI) protocol. For example, a first device that includes PHY component(s) may be located remotely with respect to one or more other entities that manage and control it. In one example, a second device generates (core receives from another device) a MAC message that is based on the PMI protocol and generates a PHY message based thereon. This first device and then transmits the PHY message to the first device for use by the first device to configure PHY operational parameter(s). Generally, different messages are communicated between devices based on the PMI protocol. The first device, which may generally be referred to as a remote PHY device (RPD), can be managed and controlled by one or more other devices located separately therefrom.

Abstract: A network device includes one or more memories and one or more processor circuits coupled to the one or more memories. The one or more processor circuits are configured to cause providing for transmission a request directed to a network controller to change a power state of the network device, receiving a grant from the network controller in response to the request, and changing the power state of the network device in response to receiving the grant. The power state of the network device includes a running power state and a standby power state, where the standby power state includes an active mode and an idle mode. A network controller for granting a request from the network device to change a power state of the network device is also disclosed.

Abstract: Embodiments include, but are not limited to, systems and methods for enabling Orthogonal Frequency Division Multiple Access (OFDMA) in the upstream in an Ethernet Passive Optical Network over Coax (EPoC) network. Embodiments include systems and methods for translating Ethernet Passive Optical Network (EPON) upstream time grants to OFDMA resources represented by individual subcarriers of an upstream OFDMA frame. In an embodiment, the translation of EPON upstream time grants to OFDMA resources ensures that Coaxial Network Units (CNUs) sharing an OFDMA frame do not use overlapping subcarriers within the frame. Embodiments further include systems and methods for timing upstream transmissions by the CNUs in order for the transmissions to be received within the same upstream OFDMA frame at a Fiber Coax Unit (FCU). Embodiments further include systems and methods for re-generating a data burst from OFDMA resources for transmission from the FCU to an Optical Line Terminal (OLT).
