摘要： 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.

摘要： 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. Session control is passed from one device to another during a contention-free interval following the exchange of appropriate connection control messages between the devices.
摘要翻译： CSMA媒体访问控制（MAC）方案，用于在CSMA网络中支持集中式和分布式共享介质访问控制。在使用面向竞争的访问期间，主设备与从站交换连接控制消息，以建立连接和会话的定期无竞争间隔。一旦会话建立，无争用间隔根据连接控制消息指定的定时参数与面向竞争的间隔交替。每个无争用间隔被划分为时隙，主机在下行帧中发送，从设备在下一个时隙中发送上行帧，如果下行帧指示与主设备的源地址匹配的源地址，则无争用以最高优先级访问和与主设备和从设备之间建立的连接相对应的连接号，从而下行帧用于轮询从设备并触发从设备的上游帧。在无争用间隔期间，使用附加控制信息，更准确地说，用于指示哪个设备具有主控制的主标志和用于指示正在通过主控制的方向的控制标志，主控制从一个设备传递到另一个设备。使用使用面向对象访问的连接控制消息进行更改会话参数或更改会话控制的安排。在设备之间交换适当的连接控制消息之后的无争夺间隔期间，会话控制从一个设备传递到另一个设备。

摘要： 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.

摘要： 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. Each station listens for channel access priority levels of other stations and may signal its own channel access priority level during a priority resolution period preceding the contention period. The channel access priority is signaled as a two bit value and the priority resolution period includes two priority resolution slots corresponding to the two bit value and is used to separate higher channel access priority values from lower channel access priority values.

摘要： 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.
