1. A method of transmitting a pilot on a downlink in a wireless multi-carrier communication system, comprising:

  • generating pilot symbols for transmission on a first set of subbands, wherein the first set of subbands is used for pilot transmission by a first transmitting entity and is disjoint from a second set of subbands used for pilot transmission by a second transmitting entity;

    processing the pilot symbols to obtain a pilot signal having the pilot symbols included in the first set of subbands; and

    transmitting the pilot signal from the first transmitting entity.
