Abstract

Radio network node (110) and method (500) in a radio network node (110), for wireless communication with a user equipment (120) in a wireless communication system (100) in antenna streams, wherein the radio network node (110) comprises a plurality of antenna elements (210-1, 210-2, 210-n), forming a multiple antenna array (210) which is configured for massive MIMO transmission. The method (500) comprises beamforming (501) a signal to be transmitted to the user equipment (120) by splitting and phase shifting said signal; detecting (502) a peak of power of one beamformed (501) signal, exceeding a threshold value; manipulating (503) said signal until the peak of power of the signal is lower than said threshold value; and transmitting (504) said signal, to be received by the user equipment (120).

Description

technical field [0001] Embodiments described herein generally relate to a radio network node and a method in a radio network node. More specifically, this paper describes a mechanism for communicating wireless signals with antenna streams in a multi-antenna environment. Background technique [0002] A user equipment (UE), also called a mobile station, a wireless terminal and / or a mobile terminal, is capable of wireless communication in a wireless communication network, sometimes referred to as a cellular radio system. Communications may take place, eg, between UEs, between a UE and a wired telephone, and / or between a UE and a server, over a radio access network (RAN) and possibly one or more core networks. Wireless communications may include a wide variety of communication services such as voice, messaging, data packets, video, broadcast, and so on. [0003] A UE may also refer to a wireless capable mobile phone, cellular phone, tablet or notebook computer, and the like. ...
