Abstract
A method for operating a communication device includes receiving a first transmission including a first signal on one or more resources associated with signal reception, deriving a receive filter in accordance with the received first transmission, deriving a transmit filter in accordance with the receive filter, precoding a second signal with the transmit filter, thereby producing a second transmission, and transmitting the second transmission.
Claims43
A computer implemented method for operating a communications device, the method comprising:
- receiving, by the communications device from one or more access nodes, a first transmission including a first signal on one or more resources associated with signal reception, the first transmission being transmitted on a plurality of first transmission ports;
- deriving, by the communications device, a receive filter in accordance with the received first transmission;
- deriving, by the communications device, a transmit filter in accordance with the receive filter;
- precoding, by the communications device, a second signal with the transmit filter, thereby producing a second transmission;
- and
- transmitting, by the communications device to the one or more access nodes, the second transmission on a plurality of second transmission ports, the second transmission having a same number of transmission ports as the first transmission.
(canceled)
The method of claim ii, wherein the end criterion comprises at least one of a signal plus interference to noise ratio (SINR) meeting a threshold, or the communications device receiving an instruction to stop training.
A computer implemented method for operating an access node in a training mode, the method comprising:
- precoding, by the access node, a first signal with a transmit filter, thereby producing a first transmission;
- transmitting, by the access node to a communications device, the first transmission on a plurality of first transmission ports;
- receiving, by the access node from the communications device, a second transmission including second signal on resources associated with signal reception, the second transmission transmitted on a plurality of second transmission ports and including a same number of transmission ports as the first transmission;
- deriving, by the access node, a receive filter in accordance with the received second transmission;
- and
- deriving, by the access node, the transmit filter in accordance with the receive filter.
A communications device comprising:
- a memory storage comprising instructions;
- and
- one or more processors in communication with the memory storage, wherein the one or more processors execute the instructions to:
- receive, from one or more access nodes, a first transmission including a first signal on one or more resources associated with signal reception, wherein the first transmission is transmitted on a plurality of first transmission ports;
- derive a receive filter in accordance with the received first transmission,
- derive a transmit filter in accordance with the receive filter,
- precode a second signal with the transmit filter, thereby producing a second transmission, and
- transmit, to the one or more access nodes, the second transmission on a plurality of second transmission ports, the second transmission having a same number of transmission ports as the first transmission.
An access node comprising:
- a memory storage comprising instructions;
- and
- one or more processors in communication with the memory storage, wherein the one or more processors execute the instructions to:
- precode a first signal with a transmit filter, thereby producing a first transmission;
- transmit, to a communications device, the first transmission on a plurality of first transmission ports,
- receive, from the communications device, a second transmission including second signal on resources associated with signal reception, wherein the second transmission is transmitted on a plurality of second transmission ports and includes a same number of transmission ports as the first transmission, derive a receive filter in accordance with the received second transmission, and derive the transmit filter in accordance with the receive filter.
