Abstract

A transmitting unit for use in sending data in packets in timeslots within time frames, each packet being sent in a timeslot, the unit comprising means to reserve for uplink transmission in the next uplink time frame a number of timeslots (X), the number of timeslots (X) being determined dependent upon a value which is the number of timeslots (Y) used for uplink transmission in the previous uplink time frame plus the number of packets (Z) remaining for uplink transmission during the last time frame minus the number of time slots (Q) to be used in the present uplink time frame.

Claims

1. A transmitting unit for sending data in packets in timeslots within time frames, each packet being sent in a timeslot, the unit comprising means to reserve for uplink transmission in the next uplink time frame a number of timeslots, and means for determining said number of timeslots being determined as the number of timeslots used for uplink transmission in the previous uplink time frame plus the number of packets remaining for uplink transmission during the last uplink time frame minus the number of time slots to be used in the present uplink time frame.

2. A transmitting unit according to claim 1, which is a modem.

3. A transmitting unit according to claim 2, which is a wireless modem, the packets being sent by radio.

4. A network comprising the transmitting unit according to claim 1, and a receiving unit operative to transmit to the transmitting unit information of time slots allocated in the next uplink frame and to receive the packets sent by the transmitting unit.

5. A method of sending data in packets in timeslots within time frames, each packet being sent in a timeslot, the method comprising reserving for uplink transmission in the next uplink time frame a number of timeslots, said number of timeslots being determined as the number of timeslots used for uplink transmission in the previous uplink time frame plus the number of packets remaining for uplink transmission during the last uplink time frame minus the number of time slots to be used in the present uplink time frame.
