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. The allocation of bandwidth between the dedicated channels and the broadcast 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. In another embodiment, two or more shared channels are provided. In another embodiment, dedicated channels can be created with different amounts of bandwidth and/or can employ modulation and/or encoding selected according to the reception quality of the recipient subscriber station.

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 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 located transmission capacity dedicated to the communication while connectionless communications 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 communciations over others. In another embodiment, two or more shared channels are provided in addition to the dedicated channels.

Abstract: Un canal de datos para transmitir datos desde un transmisor a uno o mas de una pluralidad de receptores, cada uno de los cuales reporta intermitentemente al transmisor su calidad de recepcion de senales transmitidas por el transmisor. El transmisor transmite los datos en cuadros que incluyen cuando menos un bloque. Cada bloque incluye el mismo numero definido previamente de simbolos de transito e incluye una porcion de encabezado y una porcion de carga util. La porcion de encabezado de cada bloque esta empacado para su transmision de una manera potente, ampliando la probabilidad de que cada receptor sera capaz de recobrarla y la porcion de encabezado incluye la informacion requerida para recuperar la porcion de carga util. La porcion de carga util esta, de conformidad con la calidad de recepcion reportada por el receptor pretendido, empacada para hacer un uso eficiente de los recursos de transmision mientras que se asegura una probabilidad razonable de que el receptor pretendido sera capaz de recuperar la carga util. La porcion de encabezado puede incluir indicaciones de la modulacion, correccion y repeticion de error de avance utilizado para empacar la carga util y puede indicar el largo de la carga util.

Abstract: A data channel to transmit data from a transmitter to one or more of a plurality of receivers, each of which intermittently reports to the transmitter its reception quality of signals transmitted by the transmitter. The transmitter transmits the data in frames which include at least one block. Each block includes the same predefined number of traffic symbols , and includes a header portion and a payload portion. The header portion of each block is packaged for transmission in a robust manner, enhancing the probability that each receive r will be able to recover it and the header portion includes information required to recover the paylo ad portion. The payload portion is, in accordance with the reception quality reported by the intende d receiver, packaged to make efficient use of the transmission resources while ensuring a reasonable probability that the intended receiver will be able to recover the payload. The header portion ca n include indications of the modulation, forward error correction and repetition utilized to package the payload and can indicate the length of the payload.

Abstract: A data channel for transmitting data from a base station to subscriber stations is provided. Each subscriber station has a different service-class which reflects the reception-quality of the data transmitted from the base station. The data channel is organized into a plurality of frames. Each frame contains service-class information that is packaged in the frame in such a manner that all subscriber stations can recover the service-class information. The frame also includes payload data destined for at least one of the subscriber stations. The payload data is packaged in the frame in such a manner that the subscriber station having payload data destined therefore can recover its payload data, regardless of its service class. Subscriber stations that have no payload data destined therefore, and/or which are in a poorer service-class than the destined subscriber-stations, can use the service-class information to determine that the remainder of the frame can be ignored. An apparatus, system and method relating to the data channel are also provided.

Abstract: A novel communication channel structure and method in a wireless communication system is provided. In an embodiment of the invention, the communication system includes a base station and a plurality of subscriber stations and the subscriber stations are given access to a variety of channels, including at least one uplink data channel. The uplink data channel can operate in at least a random access mode and a polled access mode. The base station informs each subscriber station it serves of the current mode of the uplink channel via an associated downlink signaling channel and, in random access mode, each subscriber station is able to randomly access the shared uplink channel. In polled mode, each subscriber station waits for permission from the base station before sending data over the shared uplink channel. A method of operating the system monitors the collisions which occur on the uplink channel in random mode and/or the amount of data and/or the data's priority level and/or QoS requirements and switches the system between random and polled modes as appropriate. In polled mode, the method determines which subscriber stations should access the uplink and when.
