AI Technical Summary

Problems solved by technology

Even if the physical directions from the UE to the two transmit / receive points (TRP) are quite different, reflections can cause leakage between the TRP signals at the UE; this leakage will act as interference
At high SNR, the system is not limited by noise but by interference
Sometimes, the signals may interfere with each other

Embodiment Construction

[0032] introduce

[0033] Embodiments will now be described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. It will be understood that the drawings are not necessarily drawn to scale. Features described and / or illustrated with respect to one embodiment may be used in the same or similar manner in one or more other embodiments and / or in combination with or instead of features of other embodiments.

[0034] Various embodiments of systems and methods for managing interference between two signals transmitted to a single electronic device in a wireless network are described below with reference to the accompanying figures. The interference management process may be performed in an automated manner by the respective devices to detect interference between two signals, trigger the interference management method, and reduce the impact of the interference or increase the benefit from the interference.

Abstract

Systems and methods for managing interference in a communication network include transmitting a first downlink signal (50) from a first transmit / receive point (TRP) (46) to an electronic device (14) using a beam (62). The electronic device (14) can also receive a second downlink signal (52) from a second TRP (48), where a portion (54) of the first downlink signal (50) from the first TRP (46) interferes with the second downlink signal (52). The first TRP (46) then receives a series of uplink pilot signals (66, 68) from the electronic device (14). Using the received uplink pilot signals (66, 68), the first TRP (46) can then estimate the angle of departure (AoD) for the intended signal (first downlink signal (50)), and the AoD for the interference signal (54). The first TRP (46) can then reconfigure the beam (62) used to transmit the first downlink signal (50) based on the estimated AoDs for the intended signal and interference signal to manage the interference effect that the first leakage signal (54) has on the second downlink signal (52).

Description

[0001] relevant application data [0002] This application claims the benefit of Swedish Patent Application No. 1830273-7 filed on September 28, 2018, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The technology of the present disclosure relates generally to wireless communication between electronic devices in a network environment, and more particularly to a method and apparatus for managing interference in a system having multiple transmission / reception points communicating with electronic devices. Background technique [0004] The demand for data services on wireless communication systems continues to grow. Next generation wireless systems are being developed due to widespread commercialization of fourth generation (4G) wireless systems such as the Long Term Evolution (LTE) system or the LTE Advanced (LTE-A) system standardized by the Third Generation Partnership Project (3GPP). . One such system proposed by 3GPP i...
