Beamforming signaling in a wireless network

A wireless device comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
• receive, from a first node, a measurement information message comprising at least one information element;
• receive, based on the at least one information element, first signals from the first node and second signals from a second node;
• transmit, to the first node, channel state information comprising a precoding matrix indicator (PMI) determined based at least in part on the first signals received from the first node and the second signals received from the second node;
• and
• receive, from the first node, at least one data packet beamformed according to a precoding matrix associated with the PMI.

A method comprising:

• transmitting, by a first node and to a wireless device, a measurement information message indicating first signals associated with the first node and second signals associated with a second node;
• receiving, by the first node and from the wireless device, channel state information comprising a precoding matrix indicator (PMI) determined based at least in part on the first signals associated with the first node and the second signals associated with the second node;
• and
• transmitting, by the first node, at least one data packet beamformed according to a precoding matrix associated with the PMI.

A first node comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the first node to:
• transmit, to a wireless device, a measurement information message indicating first signals associated with the first node and second signals associated with a second node;
• receive, from the wireless device, channel state information comprising a precoding matrix indicator (PMI) determined based at least in part on the first signals associated with the first node and the second signals associated with the second node;
• and
• transmit at least one data packet beamformed according to a precoding matrix associated with the PMI.

A non-transitory computer-readable medium comprising instructions that, when executed, configure a wireless device to:

• receive, from a first node, a measurement information message comprising at least one information element;
• receive, based on the at least one information element, first signals from the first node and second signals from a second node;
• transmit, to the first node, channel state information comprising a precoding matrix indicator (PMI) determined based at least in part on the first signals received from the first node and the second signals received from the second node;
• and
• receive, from the first node, at least one data packet beamformed according to a precoding matrix associated with the PMI.

A non-transitory computer-readable medium comprising instructions that, when executed, configure a first node to:

• and
• transmit at least one data packet beamformed according to a precoding matrix associated with the PMI.

A system comprising:

• a wireless device;
• and
• a first node,
• wherein the first node is configured to:
• transmit, to the wireless device, a measurement information message indicating first signals associated with the first node and second signals associated with a second node;
• and
• wherein the wireless device is configured to:
• receive, from a first node, the measurement information message;
• receive the first signals and the second signals;
• transmit, to the first node, channel state information comprising a precoding matrix indicator (PMI) determined based at least in part on the first signals and the second signals;
• and
• receive, from the first node, at least one data packet beamformed according to a precoding matrix associated with the PMI.
