摘要： A network device may be configured for communication over multiple communication networks. In one example, a method for using a network device to communicate over multiple networks is disclosed. The method includes receiving a packet from a combined communication interface and determining that the packet is formatted according to a first communication protocol. In response to determining that the packet is formatted according to the first communication protocol, the method includes enabling a first component in a first digital signal processor (DSP) block of the network device to process the packet according to the first communication protocol, and disabling a second component of the first DSP block, wherein the second component is configured to process the packet according to a second communication protocol.

摘要： Described herein is datagram segmentation and acknowledgment in a network. A communication node in the network may determine a length of a datagram is greater than a maximum protocol data unit (PDU) length of a protocol of the network and create a segmented message comprising the datagram and a payload length field indicating the length of the datagram. The node may then segment the segmented message into segments and create a PDU comprising one or more of the segments and a segment number least significant bits (LSB) field comprising least significant bits of a segment number associated with the one or more segments. The PDUs may be acknowledged using selective acknowledgment (SACK) messages. The SACK message may comprise a SACK type indicator, a segment number most significant bits (SN_MSB) indicator, and a payload comprising one or more least significant bits (LSBs) of a segment of the segmented message.

摘要： A method for determining transmission properties of a multiple-input multiple-output (MIMO) channel. In one embodiment, a MIMO receiver receives a non-beamformed, spatial-multiplexed (SM) sounding signal over multiple signal paths of the MIMO channel. The receiver determines beamforming information including beamforming coefficients and beamforming Eigenvalues for the MIMO channel based, at least in part, on frequency responses of the signal paths. The receiver determines a first signal-to-noise ratio (SNR) estimate for one or more SM data streams of the SM sounding signal based, at least in part, on the determined beamforming information.

摘要： A first powerline communication device, associated with a first powerline communication network, determines a plurality of time intervals in a beacon period of the first powerline communication network based, at least in part, on variations in levels of interference from a second powerline communication network which shares a powerline communication medium with the first powerline communication network. The first powerline communication device determines at least one channel adaptation parameter for each of the plurality of time intervals in the beacon period to compensate for effects of the variations in the levels of interference from the second powerline communication network. The first powerline communication device applies the at least one channel adaptation parameter corresponding to one or more of the plurality of time intervals in the beacon period when transmitting data via the powerline communication medium.

摘要： A Response Interframe Space (RIFS) time period may be adapted in a communication system. The RIFS time period may be based, at least in part, on channel conditions (e.g., data rate) between a first device and a second device. The RIFS may be optimized in consideration of channel conditions for a particular communications channel and/or characteristics of a particular physical layer transmission. In one embodiment, the RIFS may be dependent on characteristics of a final modulation symbol in a physical layer transmission. The final modulation symbol may include more than one PHY blocks (PBs) or portions of PBs. The RIFS may depend on a number of PBs that end in the final modulation symbol.
