First Claim
Patent Images
1. A method for wireless communications, comprising:
- transmitting a reference signal in a first group of tones;
transmitting an offsetting reference signal in a second group of tones, wherein the offsetting reference signal is suitable for at least partially cancelling the reference signal when combined with the reference signal; and
transmitting data in a third group of tones.

Abstract
Certain aspects of the present disclosure relate to a method for coordinated multipoint wireless communications. A technique for joint processing of misaligned reference signals in coordinated multipoint communications is provided. In one aspect, a cell may transmit an offsetting reference signal which, when processed by a receiving user equipment, at least partially cancels a first reference signal transmitted by the cell.
