Abstract

A base station transmits a first unicast control message configuring transmission parameters of a first carrier for a wireless device. The base station transmits at least one second unicast message configuring measurement parameters of a second carrier. The measurement configuration comprises a first and a second measurement subframe allocation bitmap for the second carrier. The base station receives first and second channel state information from the wireless device. The base station transmits data packets to the wireless device. The data packets are encoded and modulated based on the first and second channel state information.

First claim

What is claimed is:

1. A base station comprising:
a) one or more communication interfaces;
b) one or more processors; and
c) memory storing instructions that, when executed, cause said base station to:
i) broadcast first parameters identifying a first set of subframes on a primary carrier as almost blank subframes;
ii) transmit to a wireless device at least one unicast control message comprising:
(1) second parameters identifying a second set of subframes on a secondary ca…
