摘要： A duty cycle scheme for wireless communication employs three or more duty cycle levels. In some aspects, a wireless device may continually scan for signals in an active state associated with a first duty cycle, periodically scan for signals during a periodic state associated with a second duty cycle, and periodically scan for signals during a standby state associated with a third duty cycle. Here, the second duty cycle may be lower than the first duty cycle and the third duty cycle may be lower than the second duty cycle. In some aspects the timing of different states may be correlated. In some aspects each wireless device in a system may independently control its duty cycle states.

摘要： In an addressing scheme for wireless communication a communication channel may be defined based on a unique identifier associated with a destination node or a source node. In addition, a short identifier may be included in messages sent over the communication channel such that a node may uniquely identify the source node or destination node for the message. A node may use a short identifier as an index into a lookup table to determine one or more parameters to be used for communicating with another node.

摘要： A transmitting device transmits data to one or more receiving devices. At least one of the receiving devices transmits a keep-alive to the transmitting device. The keep-alive is transmitted at a reduced rate relative to the data transmission rate. In some implementations multiple receiving devices may transmit keep-alives. In these cases, each receiving device may transmit its keep-alives according to a schedule to prevent or reduce the likelihood of overlapping keep-alives. In some implementations a receiving device may be selected to transmit keep-alives. Here, if the selected receiving device stops transmitting keep-alives another receiving device is selected to transmit keep-alives. Through the use of the above techniques, the transmitting device need not keep track of which receiving devices are listening to the data transmission. Rather, the transmitting device may simply stop transmitting in the event that it no longer receives keep-alives.

摘要： A communications method comprising the steps of receiving a data packet; processing the data packet; and transmitting an ack packet approximately at an end of a first defined time interval if the processing of the data packet is completed within the first defined interval, or transmitting the ack packet approximately at an end of a second defined time interval if the processing of the data packet is not completed within the first defined interval and is completed within the second defined interval. Another communication method comprising the steps of transmitting a data packet; scanning a channel for an ack packet approximately at an end of a first defined time interval from the transmission of the data packet; and scanning the channel for the ack packet approximately at an end of a second defined time interval from the transmission of the data packet if the ack packet was not received within the first defined interval.

摘要： A channel access scheme is provided for a pulse-based ultra-wide band network. Here, concurrent ultra-wide band channels may be established through the use of a pulse division multiple access scheme. An access scheme may employ different states each of which may be associated with different channel parameter state information and/or different duty cycles. For example, a channel access scheme may employ an inactive state, an idle state, a connected state, and a streaming state. Multiple logical channels may be defined for a given ultra-wide band channel via, for example, pulse division multiplexing.

摘要： Media access control is provided for an ultra-wide band medium. The media access control may employ a peer-to-peer network topology. The media access control may employ a reduced addressing scheme. Concurrent ultra-wide band channels may be established through the use of a pulse division multiple access channelization scheme. Multiple media access control states may be defined whereby each state may be associated with one or more of different channel parameter state information, different duty cycles, and different synchronization status.
