Embodiments of an enhanced directional multi-gigabit (EDMG) station (STA), access point (AP), and method of communication are generally described herein. The EDMG STA may receive, from the AP, a Link Measurement Request Frame that includes a request for information for time division duplexing (TDD) rate adaptation. The EDMG STA may transmit a Link Measurement Response Frame that includes a Directional Multi Gigabit (DMG) Link Margin element that includes a Rate Adaptation Control parameter. The DMG Link Margin element may be configurable to include one or more optional fields for the TDD rate adaptation and transmit power control. The Rate Adaptation Control parameter may indicate: a number of space time streams (STSs) for which information is included in the DMG Link Margin element; and whether the DMG Link Margin element includes the one or more optional fields.

In an example method, an edge transceiver receives a first message from a hub transceiver over a first communications channel of an optical communications network, including an indication of available network resources on the optical communications network. The edge transceiver transmits, over a second communications channel of the optical communications network, a second message to the hub transceiver, including an indication of a subset of the available network resources selected by the edge transceiver. The edge transceiver receives, from the hub transceiver, a third message acknowledging receipt of a selection by the edge transceiver and a fourth message confirming an assignment of the selected subset of the available network resources to the edge transceiver. The edge transceiver transmits, using the selected subset of the available network resources, data via the hub transceiver.

The present application discloses a long-distance transmission method for an Ethernet switch including a network switching module, an MCU module and a dial code module. The MCU module is connected to the network switching module and the dial code module. The dial code module is configured for providing two configuration inputs for a normal mode and a long-distance mode for user equipment. The MCU module is configured for monitoring a configuration input state of the dial code module in real time. When detecting that the dial code module is in the configuration input for the normal mode, the MCU module configures a network port of the network switching module to be in a self-negotiation mode. When detecting that the dial code module is in the configuration input state for the long-distance mode, the MCU module configures the network port of the network switching module to be in a 10 Mbps full-duplex mode and controls an amplitude of an output voltage of a network signal of the network switching module to increase. The network switching module is configured for negotiating a network link bandwidth of 10 Mbps and a full duplex mode between the network switching module and the user equipment for long-distance data transmission according to a configuration made by the MCU module when the dial code module is in the long-distance mode. The embodiments of the present application are applied to long-distance data transmission.

Systems and methods for random access communication in accordance with various embodiments of the invention are described in which receivers can handle uncoordinated transmissions of a large and unknown number of transmitters. Communication systems in accordance with many embodiments of the invention include a plurality of transmitters that encode message data as symbols using a rateless code. During transmission, the transmitters receive feedback messages at a predetermined set of potential decoding times until an end of epoch message is received. A receiver transmits at least one start of epoch message and, at each of a predetermined set of decoding times, determines whether a decoding rule is satisfied. When the decoding rule is satisfied, the receiver can decode at least one message from observed symbols based upon the rateless code. The receiver can end the transmission epoch by transmitting an end of epoch message.
