Signal acquisition in a wireless communication system

A method of transmitting pilots in a communication system, comprising:

• generating a first time division multiplexed (TDM) pilot based at least in part on a first pseudo-random number (PN) sequence in a set of possible first PN sequences for the first TDM pilot;
• generating a second TDM pilot based at least in part on a second PN sequence in a set of second PN sequences associated with the first PN sequence;
• transmitting the first TDM pilot in a first portion of each transmission interval for the first and second TDM pilots;
• and
• transmitting the second TDM pilot in a second portion of said each transmission interval.

A method of transmitting pilots in a communication system, comprising:

• identifying a pseudo-random number (PN) sequence for each of a plurality of time division multiplexed (TDM) pilots from a set of PN sequences available for each TDM pilot;
• generating the plurality of TDM pilots based on a plurality of PN sequences identified for the plurality of TDM pilots wherein an identity of a transmitting entity of the plurality of TDM pilots is associated with the plurality of PN sequences;
• and
• transmitting the plurality of TDM pilots in a plurality of time intervals of each transmission interval with TDM pilot transmission.
