Abstract
An apparatus for providing wireless coverage to a plurality of sectors includes means for generating a reference sequence, and means for applying a time domain orthogonal sequence to the reference sequence to generate a reference signal for broadcasting over one of the sectors. An apparatus for wireless communications within a sector includes means for receiving a broadcast within a sector, the received broadcast comprising a reference signal having a time domain orthogonal sequence applied to a reference sequence, and means for recovering the reference sequence from the received broadcast.

An apparatus for providing wireless coverage to a plurality of sectors, comprising:
- means for generating a reference sequence;
- and
- means for applying a time domain orthogonal sequence to the reference sequence to generate a reference signal for broadcasting over one of the sectors.
An apparatus for wireless communications within a sector, comprising:
- means for receiving a broadcast within a sector, the received broadcast comprising a reference signal having a time domain orthogonal sequence applied to a reference sequence;
- and
- means for recovering the reference sequence from the received broadcast.
A method for providing wireless coverage to a plurality of sectors, comprising:
- generating a reference sequence;
- and
- applying a time domain orthogonal sequence to the reference sequence to generate a reference signal for broadcasting over one of the sectors.
A method for wireless communications within a sector, comprising:
- receiving a broadcast within a sector, the received broadcast comprising a reference signal having a time domain orthogonal sequence applied to a reference sequence;
- and
- recovering the reference sequence from the received broadcast.
An apparatus for providing wireless coverage to a plurality of sectors, comprising:
- a processing system configured to generate a reference sequence, and apply a time domain orthogonal sequence to the reference sequence to generate a reference signal for broadcasting over one of the sectors.
An apparatus for wireless communications within a sector, comprising:
- a processing system configured to receive a broadcast within a sector, the received broadcast comprising a reference signal having a time domain orthogonal sequence applied to a reference sequence, the processing system being further configured to recover the reference sequence from the received broadcast.
