Abstract:
A method of transmitting scheduling information by a wireless communication device (200) to a network (112) for allocation of resources to the wireless communication device, comprises the steps of transmitting (500) to the network first scheduling information (SI1) relating to a first resource requirement and re-transmitting (516) the first scheduling information when the first scheduling information is not received by the network. Second scheduling information (SI2) relating to a second resource requirement subsequent to the first resource requirement is transmitted (512) to the network (112) in response to one of the first scheduling information having been received by the network and the first scheduling information having not been received by the network after a predetermined number of re-transmissions of the first scheduling information. The generation of scheduling information may be initiated in response to a trigger event such as a periodic trigger event or a non-periodic trigger event.
Abstract:
A TIME DIVISION MULTIPLEXED SYSTEM (100) IS DISCLOSED IN WHICH COMMUNICATION MESSAGES AMONG A WIDE AREA SITE (W) AND A PLURALITY OF SUBSTANTIALLY SCATTERED LOCAL SITES (L1-L6) ARE COMMUNICATED ON A RADIO FREQUENCY CHANNEL WHICH IS DIVIDED INTO A PLURALITY OF TIMES SLOTS (550), WHEREIN AT LEAST ONE OF THE TIME SLOTS IS FURTHER DIVIDED IN TO A PLURALITY OF SUB SLOTS (510-540). COMMUNICATION UNITS (108) OPERATING IN THE WIDE AREA SITE (W) COMMUNICATE COMMUNICATION MESSAGES DURING THE TIME SLOTS , AND THE COMMUNICATION UNITS (103) OPERATING IN THE LOCAL SITES (L1-L6) COMMUNICATE COMMUNICATION MESSAGES DURING THE SUB SLOTS WHICH ARE ASSIGNED TO EACH OF THE LOCAL SITES.

Abstract:
A communication system that provides TDM and FDM communications between communication units. At least two control slots are provided in each TDM frame window to provide communication control information such as channel assignment information.
Abstract:
A method of providing a communication unit (10) access to a shared communication resource. In the communication unit, a clock (123) is maintained, and the unit detects the time when an inhibit period on the shared communication resource begins, and the time at which it concludes. When access to the shared communication resource is desired, the unit attempts to access the communication resource based on the time at which access was desired, as well as the times at which a detected inhibit condition began and concluded. A virtual time clock runs only during non-inhibit periods. Access to the communication resource is then based on when the virtual time clock equals the desired access time.
Abstract:
A time division multiplexed system is disclosed in which communication messages among a wide area site and a plurality of substantially scattered local sites are communicated on a radio frequency channel which is divided into a plurality of time slots, wherein at least one of the time slots is further divided into a plurality of subslots. Communication units operating in the wide area site communicate communication messages during the time slots, and the communication units operating in the local sites communicate communication messages during the subslots which are assigned to each of the local sites.
Abstract:
A radio communication system controller embodies the present invention by providing extended use (306) of a communication resource (106) to a plurality of communication units. The inventive method includes the steps of assigning (402) a first communication resource to a first communication unit, and then temporarily configuring (406) the assigned communication resource as a reserved resource. The controller then receives (408), from a second communication unit, a request to transmit a second communication on the assigned communication resource. Lastly, the controller re-configures (412) the assigned communication resource to allow transmission of the second communication on the assigned communication resource.
Abstract:
En un sistema de comunicación, un método caracterizado por lasetapas de: - Recibir (401) al menos un paquete de información destinado a la subsiguiente transmisión saliente;- Recibir (4O3) al menos un pedido de reservación que corresponde a, por lo menos, un paquete de información destinado a la subsiguiente transmisión entrante; - Seleccionar (407) de entre al menos el único paquete de información y al menos el único pedido de reservación para lograr que, como mínimo, un paquete de información seleccionado sea transmitido; - Asignar (409) al menos una parte de un recurso de comunicación para soportar la transmisión de al menos el único paquete de información seleccionado.
