Abstract
A method and apparatus are provided that allows a predetermined training sequence to be selected from among different choices. According to one aspect of the present invention, the invention includes receiving a downlink broadcast burst from a base station, determining timing for sending an uplink burst, selecting a training sequence for the uplink burst; and transmitting the uplink burst using the selected training sequence.
Claims18
A method comprising:
- receiving at a receiving station a downlink broadcast burst from a base station;
- determining timing for transmitting an uplink burst;
- selecting a training sequence at the receiving station for the uplink burst by determining a digit from a number stored in the receiving station, the number being unique to each receiving station, and applying the determined digit to select from among a set of predetermined training sequences;
- and
- transmitting the uplink burst from the receiving station using the selected training sequence.
A machine-readable medium having stored thereon data representing sequences of instructions which, when executed by a machine, cause the machine to perform operations comprising:
- receiving at a receiving station a downlink broadcast burst from a base station;
- determining timing for transmitting an uplink burst;
- selectin a training sequence at the receiving station for the uplink burst by determining a digit from a number stored in the receiving station, the number being unique to each receiving station, and applying the determined digit to select from among a set of predetermined training sequences;
- and
- transmitting the uplink burst from the receiving station using the selected training sequence.
An apparatus comprising:
- a receiver to receive a downlink broadcast burst from a base station;
- a processor to determine timing for sending an uplink burst, and to selecting a training sequence at the receiving station for the uplink burst by determining a digit from a number stored in the receiving station, the number being unique to each receiving station, and applying the determined digit to select from among a set of predetermined training sequences for the uplink burst;
- and
- a transmitter to transmit the uplink burst using the selected training sequence.
