Embodiment Construction

[0027] Hereinafter, exemplary embodiments of the present invention will be described in more detail. It must be understood that the following description is given for the purpose of illustrating the principles of the invention only and is not taken in a limiting sense. Rather, the scope of the present invention is defined only by the appended claims, and is not intended to be limited by the exemplary embodiments described hereinafter.

[0028] The illustrated embodiment relates to control of beamforming as applied to radio transmissions between a first radio communication device and a second radio communication device. Examples of corresponding scenarios are in figure 1 shown in figure 1 A UE 10 in a cellular network and a base station 100 of the cellular network are illustrated. The UE 10 may correspond to, for example, a mobile phone, a tablet computer, a laptop computer, or some other kind of mobile or stationary communication device. The cellular network may for exampl...

Abstract

A radio communication device applies a beamforming pattern defining plurality of beams (411, 412, 413, 414, 415, 416, 417). From the plurality of beams (411, 412, 413, 414, 415, 416, 417), the radio communication device selects at least one main beam (412) and a set of auxiliary beams (411, 413). Exclusively on the at least one main beam (412), the radio communication device sends radio transmissions to a further radio communication device (420). Further, the radio communication device monitors signals transmitted by the further communication device (420) on the at least one main beam (412) and the set of auxiliary beams (411, 413). Depending on the monitored signals, the communication device reselects at least one beam from the set of auxiliary beams as the at least one main beam.

Description

technical field [0001] The present invention relates to a method of controlling beamforming and a correspondingly configured apparatus. Background technique [0002] In radio communication networks, such as cellular networks, there is often a need for increased capacity and performance, which can be addressed, for example, by using higher frequencies (eg in the range above 15 GHz). However, the move to increased frequencies at the same time generally results in a reduced aperture area of ​​the antenna used to perform the radio transmission. Consequently, the performance of radio transmissions may become sensitive to the relative positioning or orientation of the transmitter and receiver. [0003] The solution to this reduced aperture area is to use an array antenna to apply a beamforming mechanism. By means of this beamforming mechanism, the transmit power of the array antenna may be focused on a specific spatial direction, which results in a two-dimensional or three-dimen...
