摘要： Power save proxy functionality can be implemented to enable power save devices to switch to a power save mode and still receive communications from legacy communication devices. A first communication device determines that a second communication device is in a power save mode. The first communication device designates itself as a power save proxy for the second communication device that is in the power save mode. In response to detecting packets that are transmitted from a legacy communication device to the second communication device, the first communication device transmits a control message to the second communication device to request the second communication device to exit the power save mode, transmits a hold control message to the legacy communication device to request the legacy communication device to temporarily stop transmitting packets to the second communication device, or stores the packets intended for the second communication device.

摘要： A waveform communicated from a first station to a second station over the shared medium may be communicated at a time that is based on a shared time reference shared by the first and second stations. The waveform may include at least a first symbol, having a predetermined symbol length, comprising a first set of frequency components at predetermined carrier frequencies modulated with preamble information and a second set of frequency components at predetermined carrier frequencies modulated with frame control information. The carrier frequencies of the first and second sets of frequency components may be integral multiples of a frequency interval determined by the inverse of the symbol length. The first symbol of the waveform may be demodulated in response to detecting a series of values sampled based on the shared time reference.

摘要： Communication systems that use different physical layer (PHY) protocols can coexist on a communication medium (e.g., a powerline medium) by using an Inter-PHY Protocol (IPP). The different protocols may use different signal modulation schemes but still may have some features in common. The IPP includes a resource sharing mechanism that regulates access to the communication medium by devices functioning as communication devices (for example, devices communicating over a power line). A subset of devices that communicate among each other form a logical network that shares the medium with other logical networks that use either the same PHY protocol or a different PHY protocol.

摘要： A powerline network may comprise powerline communication (PLC) devices of a first class of PLC devices that are incompatible with PLC devices of a second class of PLC devices. This can result in interference between communications of the first and the second classes of PLC devices. A dual mode PLC device that is compatible with the first and the second classes of PLC devices can be implemented for coexistence with both classes of PLC devices. The dual mode PLC device can determine whether the powerline network comprises a combination of PLC devices of the first and the second classes of PLC devices. One of a plurality of packet headers that is compatible with both the classes of PLC devices can be selected for transmission in response to determining that the powerline network comprises a combination of PLC devices of the first and the second classes of PLC devices.

摘要： A method is described for communicating among multiple devices over a shared communication medium. The method includes, in a schedule among multiple subsets of the devices that includes at least one respective time slot for each subset, transmitting from at least one of the devices in a given subset a presence signal associated with the given subset within a time slot for the given subset. A presence signal associated with a given subset is configured to indicate the presence of at least one device in the given subset. The method also includes communicating among devices in a given subset based on presence signals detected from one or more devices in at least one different subset.

摘要： Methods of operating in a network in which a plurality of stations communicate over a shared medium and contend for access during a priority resolution period. At least some of the stations use a first CSMA network protocol having certain characteristics (e.g., some transmissions have a format that includes a start of frame delimiter (SOF), a payload, and an end of frame delimiter (EOF), wherein the SOF and EOF each contain sufficient information to permit a station receiving only one of the SOF and EOF to determine the start of a priority resolution period). And at least some stations use a second network protocol capable of coexisting with the first protocol, so that stations may communicate using either the first or second protocol. The second protocol may have various characteristics configured to achieve coexistence with the first protocol (e.g., transmissions that have a format that includes an SOF but not an EOF).
