Time orthogonalization of reference signals

摘要

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.

1. A method for providing wireless coverage to a plurality of sectors, comprising:
generating a reference sequence; applying a time domain orthogonal sequence to the reference sequence to generate a reference signal for broadcasting over one of the plurality of sectors, wherein applying the time domain orthogonal sequence comprises:
splitting the reference signal into parallel streams with each stream carrying a reference sequence value for a period of time, the reference sequence values together constituting a time symbol; andmultiplying reference sequence values in different time symbols with a different constant value; generating the reference signal based at least in part on the application of the time domain orthogonal sequence to the reference sequence; and broadcasting the reference signal over one of the plurality of sectors.
