1. A method for wireless communication, comprising:
- determining, at a base station, a data allocation size from a data region of at least one subframe for a data transmission to a user equipment (UE);
signaling the data allocation size to the UE in a downlink assignment;
determining a bundling size based at least in part on the data allocation size and a delay spread; and
precoding at least one reference signal in bundled contiguous resource blocks of the determined bundling size, wherein the at least one reference signal in each bundle is precoded with a common precoding matrix.

Abstract
Provided is a method for wireless communication which includes determining a data allocation size available for data to be transmitted, determining a bundling size based at least in part on the data allocation size, and precoding at least one reference signal in bundled contiguous resource blocks of the determined bundling size. The at least one reference signal in resource blocks in each bundle are precoded with a common precoding matrix.
