摘要： A method of operating a communication system is disclosed. The method includes transmitting from a remote unit to a base station remote unit channel data. The remote unit channel is generated at the remote unit and includes data about a first portion of communication channels on which the call can be executed. The method also includes applying a channel selection method to the remote unit channel data and to base station channel data so as to select a communication channel from among the first portion of communication channels. The base station channel data is generated at the base station and includes data about a second portion of the communication channels. The method further includes executing a call on the selected communication channel.

摘要： The present invention provides methods for improving the performance and efficiency of time sharing wireless networks by reducing collisions, eliminating wasted bandwidth caused by unnecessary gaps between transmissions, and reducing the amount of control information broadcast from the base station. The present invention accomplishes this by synchronizing the actions of the remote units in the wireless network to the control messages sent by the base unit and having the base unit compensate for the inherent system latency in determining when control messages should be sent. The present invention also consolidates the functionality of some of the control messages in order to reduce bandwidth usage.

摘要： A method and an apparatus provide for controlled access to a shared communication medium. Time slots on a forward channel include information regarding status useful for remote units to determine whether a reverse channel is available for seizure. Additionally, information along the forward channel provides guidance to the remote units to control attempts to seize the reverse channel. In one embodiment a remote unit divides a data package into a plurality of portions and attempts to seize the reverse channel using a single portion of the data package which corresponds to one time slot on the reverse channel. It then waits until it receives notification along the forward channel that the first data portion was successfully received before it attempts to send any of the remainder of its data in consecutive time slots on the reverse channel.

摘要： In a wireless communications system, a data link layer and a medium access control layer are connected to each other by data and control paths, where the data path is operable to exchange frames between the data link layer and the medium access control layer and the control path is operable to exchange control messages between the data link layer and the medium access control layer. The data link layer includes a queue for storing frames received from the medium access control layer and the medium access control layer includes a queue for storing frames received from the data link layer. The data link layer is adapted to pass new data frames from a higher layer relative to the data link layer into the data link layer queue and to suspend a retransmission timer upon a congestion message received from the medium access control layer, the congestion message being responsive to a level of stored frames in the medium access control queue.
