A method for low latency data transfers between a wireless root device and a wireless endpoint device connected through a wireless peripheral-interconnect bus. The method comprises setting the wireless root device and the wireless endpoint device to operate in bi-directional low latency bus (BDLLB) mode; generating, by the wireless root device, a first data frame to be transmitted to the end-point device, wherein the first data frame includes at least a preamble, a block acknowledgment (ACK) frame and aggregation of a plurality of medium access control service data units (MSDUs) according to an order they received from a data link layer of the wireless peripheral-interconnect bus; and transmitting the first data frame to the wireless endpoint device over a wireless medium.

Bi-directional low latency bus mode

A method for enabling a low latency medium access control for an interconnect bus protocol over a wireless medium is provided. The method comprises constructing a wireless medium access control (WMAC) frame, wherein the WMAC frame includes a plurality of medium access control service data units (MSDUs) being aggregated according to their transmission order, the MSDUs include transaction layer packets generated by a component of the interconnect bus, wherein transmission of the WMAC frame over the wireless medium provides any one of an implied acknowledgment (ACK) mechanism and a block ACK mechanism.

Low latency interconnect bus protocol

A device and method for transmitting data over a wireless network, based on a low latency interconnect bus protocol. The low latency interconnect bus protocol is a layered protocol containing a Wireless Medium Access Control (WMAC) layer for constructing a WMAC frame from the data, and a Wireless Physical (WPHY) layer for constructing a WPHY frame from the WMAC frame. The WMAC frame includes an aggregation of a plurality of MAC Service Data Units (MSDUs), and is capable of providing a reliable link by implementing an implied ACK and a block ACK. The WPHY frame is configured to provide a mechanism for a bi-directional communication between components; and the content of the WPHY frame is determined according to a communication state between two communicating components.
