Abstract: System and method for transmitting data over a communications link in at least two channels. At least one transmitter transmits data in the two channels simultaneously. At least one interleaver interleaves data to be transmitted in the two channels prior to transmission by the at least one transmitter. The at least one interleaver employs different sets of interleaving parameters when interleaving data to be transmitted in different channels, such that data to be transmitted in each channel is interleaved in a different pattern than data to be transmitted in the other channel(s). At least one receiver receives the data transmitted in at least one of the two channels. A de-interleaver, associated with the at least one receiver, employs the set of interleaving parameters corresponding to the at least one channel received by the at least one receiver to de-interleave data received by the at least one receiver.

Abstract: A system for transmitting data between stations, such as base stations and subscriber stations in a wireless telecommunications system, employs variable set of interleaving parameters for its interleaving operations. By using different set of interleaving parameters with the interleavers, data which would otherwise be aligned when transmitted from a station to many stations, or from many stations to a station, will not be aligned after interleaving has been performed. This reduces the peak to average ratio required for a transmitter and/or can reduce interference experienced at receivers in the system. This is especially true if a significant proportion of the otherwise aligned signals are symbols which require zero energy to transmit.

Abstract: 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 capacity and/or network resources while providing for both types of communication. Connection-like communications can be provided by a channel having allocated bandwidth dedicated to the communication while connectionless communication can be provided by a shared channel through which data can be transmitted to subscribers. In an embodiment, the shared channel transmits frames of packets addressed to one or more of the subscribers. The frames can have a robustly packaged header that can be received by all subscriber stations serviced by the base station while payload data in the frame can be packaged with a level of robustness appropriate for the intended subscriber station. Different packagings can include different encoding and/or modulation of the payload data.

Abstract: 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 capacity and/or network resources while providing both types of communication and hybrids. Connection-like communications can be provided by a channel having allocated transmission capacity dedicated to the communication while connectionless communication can be provided by a shared channel through which data can be transmitted to subscribers. In an embodiment, the shared channel transmits frames of packets addressed to one or more of the subscribers. The allocation of transmission capacity between the dedicated channels and the shared channel can be fixed, or can be managed to meet network or network operator requirements. The structure and method can also be managed by the network operator to permit prioritization of some communications over others.
