Abstract

A wireless receives at least one channel state input information element (IE) from a first base station. The wireless device computes a precoding matrix indicator (PMI) employing, at least in part, the at least one channel state input IE and measurement of signals received at least from at least one antenna port of a second base station. The wireless device transmits channel state information comprising the PMI to the first base station. The wireless device receives at least one data packet employing beamforming according to a precoding matrix identified by the PMI.

First claim

What is claimed is:

1. A wireless device comprising:
a) one or more communication interfaces;
b) one or more processors; and
c) memory storing instructions that, when executed, cause said wireless device to:
i) receive at least one channel state input information element (IE) from a first base station, said first base station communicating with a second base station information about said at least one channel state input IE;
ii) compute a precoding matrix indicator (PMI) em…
