Beamforming Signaling in a Wireless Network

摘要

Methods, apparatus, and systems for wireless communications are described. A first base station may be configured to transmit a measurement information message to a wireless device. The measurement information message may comprise at least one information element, wherein the at least one information element indicates one or more first resource blocks corresponding to first signals associated with the first base station and one or more second resource blocks corresponding to second signals associated with a second base station. The wireless device may compute a precoding matrix indicator (PMI) based at least in part on first signals received from the first base station and second signals received from the second base station. The wireless device may transmit channel state information comprising the computed PMI to the first base station. The first base station may transmit at least one data packet beamformed according to a precoding matrix associated with the computed PMI.
