System and method to enable WUSB application in a distributed UWB MAC

A host apparatus for host-device communication in a first Wireless Universal Serial Bus (WUSB) network including the host and at least one connected device, comprising:

• a transmitter for sending beacons, traffic notifications, medium reservations and data;
• a receiver for receiving beacons, traffic notifications, medium reservations and data;
• a host data transfer processing component that processes data transferred between the host and the at least one connected device;
• and
• a controller operably coupled to the transmitter, receiver and host data transfer processing component and configured to direct the transmitter, receiver and host data transfer processing component to
• start beaconing according to a distributed Ultra WideBand Medium Access Control (UWB MAC) protocol and announce host capabilities,
• receive and process, according to a distributed UWB MAC protocol, beacons of the at least one connected device including capabilities of the at least one device,
• receive and process Device Notification Traffic (DNT traffic), and
• start and control WUSB operation of the network, wherein the controller directs the device data transfer processing component to set an offset field and a duration field in each DRP reservation to a multiple of a predetermined value if distributed reservation is supported;
• wherein the predetermined value is selected based on the combination of a desired resolution of the DRP reservation and a size of the DRP slot.

A method for host-device communication in a Wireless Universal Serial Bus (WUSB) network including a host and at least one connected device, comprising:

• beaconing according to a distributed Ultra WideBand Medium Access Control (UWB MAC) protocol by the host and the at least one connected device;
• the host establishing a multicast reservation between the host and the at least one connected device;
• and
• running a WUSB protocol inside the multicast reservation, wherein an offset field and a duration field in a Distributed Reservation Protocol (DRP) are set to a multiple of a predetermined value if distributed reservation is supported;
• wherein the predetermined value is selected based on the combination of a desired resolution of the DRP reservation and a size of the DRP slot.

A method for host-device communication in a Wireless Universal Serial Bus (WUSB) network including a host and at least one connected device, comprising:

• beaconing according to a distributed Ultra WideBand Medium Access Control (UWB) MAC protocol by the host and the at least one connected device;
• establishing unicast reservations between the host and the at least one connected device;
• and
• running a WUSB protocol inside the unicast reservations;
• wherein when the at least one connected device performs Distributed Reservation Protocol (DRP) access to indicate traffic, the host setting an offset field and a duration field in each DRP reservation to a multiple of a predetermined value if distributed reservation is supported;
• wherein the predetermined value is selected based on the combination of a desired resolution of the DRP reservation and a size of the DRP slot.

A method for host-device communication in a Wireless Universal Serial Bus (WUSB) network including a host and at least one connected device, comprising:

• beaconing according to a distributed Ultra WideBand Medium Access Control (UWB MAC) protocol by the host and the at least one connected device;
• the host using an Enhanced Distributed Channel Access (EDCA) mechanism to access the medium;
• the host polling the at least one connected device to request that the at least one connected device transmit data;
• and
• the host receiving data from the at least one connected device as a result of the poll;
• wherein
• when the at least one connected device performs Distributed Reservation Protocol (DRP) access to indicate traffic, the host setting an offset field and a duration field in each DRP reservation to a multiple of a predetermined value if distributed reservation is supported;
• wherein the predetermined value is selected based on the combination of a desired resolution of the DRP reservation and a size of the DRP slot.
