Null beamforming in a communication network

摘要

A first network device can implement null beamforming functionality to generate a NULL at a receive port of a second network device. In one embodiment, the first network device can estimate beamforming parameters to be used for transmitting the data signal to a first receive port of the second network device and for generating a null signal at a second receive port of the second network device, so that the second network device does not receive the data signal at the second receive port. In another embodiment, the first network device can estimate beamforming parameters to be used for transmitting the data signal to a receive port of the second network device and for generating a null signal at a receive port of a third network device, so that the receive port of the third network device does not receive the data signal.

1. A method comprising:
determining to transmit a first data signal from a first transmit port and a second transmit port of a first network device to a first receive port of a second network device; and determining first beamforming parameters to be used for transmitting the first data signal to the first receive port and for generating a null signal at a second receive port wherein the first data signal is received at the first receive port and not received at the second receive port.
