CROSS REFERENCE

The present application for patent claims the benefit of U.S. Provisional Patent Application No. 62/856,143 by PARK et al., entitled “OVER-THE-AIR INTERFERENCE COORDINATION,” filed Jun. 2, 2019, assigned to the assignee hereof, and expressly incorporated by reference herein.

FIELD OF TECHNOLOGY

The following relates generally to wireless communications and more specifically to over the air interference coordination.

BACKGROUND

Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include a number of base stations or network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as user equipment (UE).

Base stations and UEs may communicate using beamforming techniques. For example, a base station may communicate using transmit beams with a UE using receive beams. In some cases, however, transmit beams from a non-serving base station may interfere with the transmit beams of a serving base station that is communicating with the UE, which may lead to decoding inefficiencies or increased use of system resources (e.g., due to retransmissions), among other issues.

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support over the air interference coordination. Generally, the described techniques provide for resolving (e.g., minimizing, reducing, or eliminating) interference by utilizing over the air coordination signaling communications. A user equipment (UE) supported by a serving base station may experience interference from a neighboring base station. In such cases, the UE may send an over the air message to indicate to the neighboring base station that the UE is experiencing interference, and may request that the neighboring base station change its communication parameters. In response to the request, the neighboring base station may change one or more communication parameters, such as beam parameters, to reduce interference at the UE.
