A system and method for media access control are disclosed. The method comprises providing concurrent orthogonal channels to access media using pulse division multiple access to define pulse positions, wherein the pulse division multiple access includes a time hopping sequence and an offset to distinguish the concurrent orthogonal channels. In addition, the method comprises processing signals associated with at least one of the orthogonal channels.

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.

Some aspects include a method of associating electronic devices for communicating data. The method includes receiving a message on a first device indicating that a second device is discoverable and pairable. The method further includes determining whether the first device is pairable, transmitting a pairing response to the second device based on the determination that the first device is pairable, and pairing the first device to the second device in response to the received message and the determination that the first device is pairable. For example, some aspects include devices such as headsets, watches, and medical devices configured to use such methods for communicating data.

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.

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.

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.
