Embodiment Construction

[0031] Specific details are set forth below in order to provide a thorough understanding of embodiments of the invention. It will be apparent, however, to one skilled in the art that embodiments of the invention may be practiced without each of these specific details. In some instances, well-known wireless communication components, circuits, control signals, timing protocols, computing system components, telecommunications components, and software operations have been shown in detail to avoid unnecessarily obscuring the described embodiments of the invention.

[0032] Various devices may desire full-duplex communication. Full-duplex communication may generally refer to the ability to send and receive transmissions (in some cases, simultaneously and / or partially simultaneously). In the example of a system employing full-duplex communication, it may be desirable to cancel interference produced by other antennas in the system. Examples described herein can compensate for interf...

Abstract

Examples described herein include systems and methods which include wireless devices and systems with examples of full duplex compensation with a self-interference noise calculator. The self-interference noise calculator may be coupled to antennas of a wireless device and configured to generate adjusted signals that compensate self-interference. The self-interference noise calculator may include anetwork of processing elements configured to combine transmission signals into sets of intermediate results. Each set of intermediate results may be summed in the self-interference noise calculator to generate a corresponding adjusted signal. The adjusted signal is received by a corresponding wireless receiver to compensate for the self-interference noise generated by a wireless transmitter transmitting on the same frequency band as the wireless receiver is receiving.

Description

Background technique [0001] We are interested in advancing wireless communications to "fifth generation" (5G) systems. 5G promises increased speed and ubiquity, but the methods for handling 5G wireless communications have not yet been set up. An example 5G system may be implemented using multiple-input multiple-output (MIMO) technology, including "massive MIMO" technology, where multiple antennas (above a certain number, e.g., 8 antennas in the case of the example MIMO system) are used for wireless Transmission and / or reception of communication signals. Contents of the invention [0002] Example devices are disclosed herein. In an embodiment of the invention, an apparatus comprising: a plurality of transmit antennas; a plurality of receive antennas; a plurality of wireless transmitters configured to transmit a respective plurality of transmit signals from respective transmit antennas of the plurality of transmit antennas a plurality of wireless receivers configured to rec...
