A robust Media Access Control (MAC) scheme for network stations operating in an OFDM transmissions network. The MAC scheme uses robustly transmitted frame control information to ensure network synchronization (for media access) and convey channel access prioritization for QoS. Frame control information can occur in a frame before and after the frames payload, or in a response.

A CSMA Media Access Control (MAC) scheme for supporting both centralized and distributed shared medium access control in a CSMA network. A master device exchanges connection control messages with a slave during using contention-oriented access to establish a connection and a session of periodic contention-free intervals. Once the session is established, the contention-free intervals alternate with contention-oriented intervals according to the timing parameters specified by the connection control messages. Each of the contention-free intervals is divided into slots, the master transmitting in a downstream frame and the slave device transmitting an upstream frame in a following slot if the downstream frame indicates a source address matching that of the master device, a contention-free access at a highest priority and a connection number corresponding to the connection established between the master device and the slave device, thus downstream frame thus serving to poll the slave device and trigger the slave device's upstream frame. Master control is passed from one device to another device during the contention-free interval using additional control information, more specifically, a master flag for indicating which device has master control and a control flag for indicating the direction in which master control is being passed. Arrangements to change session parameters or change session control are made using connection control messages using contention-oriented access.

A scheme for bounding latency of transmissions for QoS in network stations operating in shared medium access network. The length of segment burst transmissions are limited by allowing the segment burst transmission of a given priority to be interrupted by higher priority traffic. Restrictions are placed on frame length for transmissions of all priority levels or, alternatively, at all but the highest of the priority levels.

A rate-adaptive mechanism for optimizing transmitter/receiver connections on a carrier-by-carrier basis for maximum date rate based on channel attributes for that connection and direction. Channel information is produced by a channel adaptation process based on channel characteristics and is stored in both transmitter and receiver as a channel map with an associated a channel map index for channel map look-up. The channel map index for a channel map used to modulate a payload of a frame is conveyed by transmitter to receiver in the frame so that the receiver is able to select the correct channel map for demodulation.

An access contention scheme having both multi-level priorities and a contention-free access indicator for use by a station in a network of stations. When a contention control indicator is detected for a contention period, a station having a frame to transmit determines from the contention control indicator if it is permitted to contend for access to the transmission medium during the contention period. The station determines if the contention control indicator indicates a contention-free access and, if the contention control information indicates a contention-free access, the station determines if a channel access priority level associated with the frame to be transmitted is higher than a channel access priority level associated with a last transmitted frame. If the channel access priority level associated with the frame to be transmitted is higher, the station detects whether any station in the network of stations intends to contend for access to the medium at a channel access priority level that is higher than the channel access priority level associated with the frame to be transmitted. If so, the station defers contention for access.

A Media Access Control (MAC) protocol scheme for binding a response to a frame that requested the response. The response specifies a portion of the frame check sequence contained in the frame. The specified portion of the frame check sequence serves to identify the response as belonging to that frame.

Media Access Control (MAC) layer transmit and receive buffering with multi-level prioritization. The receive buffering allocates receive buffers for receiving frame data from a PHY interface in priority order using both a static and dynamic buffer allocation, and delivers completed buffers queued in a multi-level priority queue to a host interface highest priority first. The transmit buffering delivers completed buffers queued in a multi-level priority queue to the PHY interface in priority order. When the multi-level priority queue contains a buffer that is higher priority than one being prepared for transmit, a priority-based interruption causes the transmit processing of the buffer to be suspended at its current state with the higher priority buffer taking its place. Upon completion of the higher priority buffer, the suspended buffer is resumed at its current state.

An access contention scheme is described for use by a station in a network of stations. Access contention by a station having a frame to be transmitted includes detecting contention control information for a contention period and determining from the contention control information if the station is permitted to contend for access to a transmission medium to which the stations are connected during the contention period. When a contention control indicator is detected for a contention period, a station having a frame to transmit determines from the contention control indicator if it is permitted to contend for access to the transmission medium during the contention period.
