Abstract
A communication transceiver (510) having a receiver (704), a controller (714) and a transmitter (710), is used for generating an unscheduled acknowledge back response. The receiver (704) receives an address and a color code identifying the cell transmitter (506) transmitting the address during a first scheduled time interval (212). The controller (714) selects, in accordance with the address received, a reserved response time slot from a predetermined number of reserved response time slots occurring during a second scheduled time interval. The transmitter (710) then transmits the unscheduled acknowledge back response during the reserved response time slot (224) selected.
Claims20
A method for providing unscheduled acknowledge back responses generated by a plurality of communication transceivers operating within a communication system which utilizes time division duplex communication and comprises a plurality of transmission cells defining geographical transmission areas, each of the plurality of transmission cells including one or more cell receivers for receiving unscheduled acknowledge back responses generated by the plurality of communication transceivers and a cell transmitter for transmitting addresses and a color code identifying the cell transmitter, the method for providing the unscheduled acknowledge back responses from communication transceivers comprising the steps of:
- receiving, at a communication transceiver, an address corresponding to the communication transceiver and the color code identifying the cell transmitter transmitting the address during a first scheduled time interval;
- selecting, in accordance with the address received, a reserved response time slot from a predetermined number of reserved response time slots occurring during a second scheduled time interval to be utilized by the communication transceiver for transmitting an unscheduled acknowledge back response ;and
- transmitting the unscheduled acknowledge back response during the reserved response time slot selected.
A communication transceiver, for use in a communication system which utilizes time division duplex communication and comprises a plurality of transmission cells defining geographical transmission areas, each of the plurality of transmission cells including one or more cell receivers for receiving an acknowledge back response generated by the communication transceiver and a cell transmitter for transmitting addresses and a color code identifying the cell transmitter, the communication transceiver comprising:
- a receiver for receiving an address and the color code identifying the cell transmitter transmitting the addresses during a first scheduled time interval;
- a controller for selecting, in accordance with the address received, a reserved response time slot from a predetermined number of reserved response time slots occurring during a second scheduled time interval to be utilized by the communication transceiver for transmitting the acknowledge back response;
- and
- a transmitter for transmitting the acknowledge back response during the reserved response time slot selected.
A communication system utilizing time division duplex communication to provide unscheduled acknowledge back responses, comprising:
- a plurality of transmission cells defining geographical transmission areas which include a plurality of cell receivers and a cell transmitter for transmitting addresses and a color code identifying said cell transmitter transmitting the addresses during a first scheduled time interval;
- a communication transceiver for receiving an address and the color code identifying the cell transmitter transmitting the address during the first scheduled time interval, the communication transceiver for selecting, in accordance with the address received, a reserved response time slot from a predetermined number of reserved response time slots occurring during a second scheduled time interval to be utilized for transmitting an unscheduled acknowledge back response, and for transmitting the unscheduled acknowledge back response during the reserved response time slot selected;
- at least one of the plurality cell receivers for receiving the unscheduled acknowledge back response transmitted within the predetermined number of reserved response time slots during the second scheduled time interval;
- and
- said cell transmitter, identified by the color code received by the at least one of the plurality of cell receivers, further transmitting addresses identifying communication transceivers for which messages are intended and the messages during one of a sequence of scheduled message transmission frames designated by the color code.
