METHOD OF AND APPARATUS FOR COMMUNICATION VIA MULTIPLEXED LINKS

摘要

A communication structure and method which allows connection-like and connectionless communications to be provided on a multiplexed link is provided. The structure and method can make efficient use of available transmission capaci ty and/or network resources while providing both types of communication and hybrids. Connection-like communications can be provided by a dedicated code divisi on multiplexed channels having allocated transmission capacity dedicated to the communication while connectionless communication can be provided by a shared orthogonal frequency division multiplexed channel through which data can be transmitted to subscribers. In an embodiment, the shared channel transmits inverse fast fourier transformed frequency sub-bands allocated to one or more of the subscribers. The allocation of the sub-bands can be fixed, or dynamically quantized or proportional.
