Problems solved by technology

However, in some cases, the transmit beams from the non-serving base stations may interfere with the transmit beams of the serving base station with which the UE is communicating, which may lead to decoding inefficiencies or increased use of system resources (e.g., due to retransmissions), among other things. question

example 1

[0247] Example 1: A method for communication at a user equipment (UE), comprising: identifying, by a UE in communication with a serving base station, that the UE is a potential victim of interference from a neighboring base station; reporting to the neighboring base station based at least in part on the identification sending an interference coordination message requesting modification of one or more transmission parameters at neighboring base stations; and communicating with the serving base station after sending the interference coordination message.

example 2

[0248] Example 2: The method of example 1, further comprising: monitoring signaling from at least one of the serving base station or a neighboring base station using a receive beam of the UE; signaling from both the serving base station and the neighboring base station based at least in part on the monitoring receiving the signaling; and identifying the UE as a potential victim of interference from neighboring base stations based at least in part on the receiving.

example 3

[0249] Example 3: The method of example 1 or 2, further comprising configuring the UE as a potential victim UE based at least in part on the identification based on the set of UE receive beams, the set of serving base station transmit beams, and the set of neighbor base station transmit beams.

Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) in communication with a serving base station may identify that the UE is a potential victim of interference from a neighboring base station. The UE may transmit an interference coordination message to the neighboring base station. The interference coordination message may request modification of one or more transmission parameters at the neighboring base station. The neighboring base station may modify its transmission parameters to decrease interference with the UE, and the UE may communicate with the serving base station after transmitting the interference coordination message.

Description

[0001] cross reference [0002] This patent application claims the benefit of U.S. Provisional Patent Application No. 62 / 856,143, filed June 2, 2019, by Park et al., entitled "Over-the-Air Interference Coordination"; and by Park et al. U.S. Patent Application No. 16 / 855,866, entitled "Over-the-Air Interference Coordination," filed April 22, 2020; each of the foregoing applications is assigned to the assignee of the present application. technical field [0003] The following relates generally to wireless communications, and more specifically to over-the-air interference coordination. Background technique [0004] Wireless communication 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 available system resources (eg, time, frequency, and power). Examples of such multiple-access systems include ...
