Abstract: A communication resource is subdivided as a function of time into a plurality of time slots (210), which may then be further subdivided on a non-periodic basis into a number of sub-slots (220). In a slot or sub-slot, communication units (101) may utilize the communication resource according to a specific set of access methods defined for that slot or sub-slot. In one embodiment the time slots are subdivided on a non-periodic basis into a least two random access sub-slots, during which communication units may either request one or more reserved time slots, or send unreserved data packets (240). In response to requests for reserved time slots from a requesting communication unit, one or more reserved time slots are provided for the use of the requesting communication unit.

Abstract: 2093909 9210889 PCTABS00014 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 time slots (550), wherein at least one of the time slots is further divided into a plurality of sub slots (510-540). Communication units (103) 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: According to the invention, an information signal is sampled, quantized and processed digitally through an information encoder (100). Digitally processed samples (1104, 1106) produced by the encoder (100) are modulated onto a communication channel to create channel symbols having a magnitude of modulation proportional to a characteristic of a respective digitally processed sample. Both a radio frequency (RF) transmission embodiment, and a wireline embodiment are provided. In a final aspect of the present invention, encryption (1101) is provided to ensure communication privacy.

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: When data is ready for transmission, a quality measurement of a communication resource is determined (303). A preferred signalling technique is determined from a plurality of signalling techniques (305). A reservation request for allocation of the communication resource is transmitted, including in the reservation request the preferred signalling technique (307). A reservation grant is transmitted according to the preferred signalling technique (309).
