Abstract
Methods, apparatus, and systems for wireless communications utilizing a precoding matrix indicator (PMI) based on first signals received from a first node and based on second signals received from a second node are described. A wireless device may receive measurement information that indicates resources of a first node and a second node for use in determining the PMI. After receiving the first signals and the second signals, the wireless device may use the first signals and the second signals to determine the PMI. The determined PMI may be sent to a base station, which may transmit one or more packets based on the determined PMI.
Claims26
A method comprising:
- receiving, by a wireless device and from a first node, measurement information;
- receiving, based on the measurement information, first reference signals from the first node and second reference signals from a second node;
- transmitting, to the first node, channel state information comprising a precoding matrix indicator (PMI) that is based on:
- the first reference signals;
- and
- the second reference signals;
- and
- receiving, from the first node and based on a precoding matrix associated with the PMI, at least one data packet.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, configures the wireless device to:
- receive, from a first node, measurement information;
- receive, based on the measurement information, first reference signals from the first node and second reference signals from a second node;
- transmit, to the first node, channel state information comprising a precoding matrix indicator (PMI) that is based on:
- the first reference signals;
- and
- the second reference signals;
- and
- receive, from the first node and based on a precoding matrix associated with the PMI, at least one data packet.
A method comprising:
- transmitting, by a first node and to a wireless device, measurement information comprising information received from a second node;
- receiving, by the first node and from the wireless device, channel state information comprising a precoding matrix indicator (PMI) that is based on:
- first reference signals associated with the first node;
- and
- second reference signals associated with the second node;
- and
- transmitting, by the first node and based on a precoding matrix associated with the PMI, at least one data packet.
A first node comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, configures the first node to:
- transmit, to a wireless device, measurement information comprising information received from a second node;
- receive, from the wireless device, channel state information comprising a precoding matrix indicator (PMI) that is based on:
- first reference signals associated with the first node;
- and
- second reference signals associated with the second node;
- and
- transmit, based on a precoding matrix associated with the PMI, at least one data packet.
