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.

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.

Aspects include methods and apparatuses for communicating in an ultra-wideband transmission. For example, some aspects include methods and apparatuses for wireless communications. The method includes, at a first device in communication with at least a second device via a wireless link, monitoring at least one resource for performing at least one function. The method further includes determining whether to assign the at least one function to the at least one second device. The determining is based on information that is indicative of at least one function and indicative of at least one resource of the at least one second device. Other aspects include apparatus and devices for communicating data, including according to one or more aspects of the method. For example, some aspects include devices such as headsets, watches, and medical devices configured to use such methods and apparatuses for communicating data.

Low power wireless communication techniques may be employed in devices that communicate via a wireless body area network, a wireless personal area network, or some other type of wireless communication link. In some implementations the devices may communicate via one or more impulse-based ultra-wideband channels. Inter-pulse duty cycling may be employed to reduce the power consumption of a device. Power may be provided for the transmissions and receptions of pulses by charging and discharging a capacitive element according to the inter-pulse duty cycling. Sub-packet data may be transmitted and received via a common frequency band. A cell phone may multicast to two or more peripherals via wireless communication links.

Systems and methods for controlling a delay associated with paging a remote device. In one implementation, a paging device arranges page operations such that if one of two consecutive page scans performed by a remote device occurs during a response scan, the other page scan occurs during the transmission of a page. In another implementation, a device scanning for a page arranges page scans such that if one of two consecutive page scans occurs during a page response scan, the other page scan occurs during the transmission of a page. In another implementation, a device scanning for a page performs a series of sets of separate page scans, wherein the time interval between two of separate scans in a set is less than the time interval between adjacent sets. The page scans in a set are configured to ensure that one of them occurs during the transmission of a page.

In accordance with aspects of the disclosure, a method, apparatus, and computer program product are provided for wireless communication. The method, apparatus, and computer program product may be configured to generate packets, wherein each of the packets comprises a packet header comprising a packet format field comprising a first indicator that indicates whether the packet header comprises a payload length field and whether the packet comprises a payload. The method, apparatus, and computer program product may be further configured to generate a second indicator based on a type of data in the payload, and attach the second indicator to the data.
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.
