Beam selection for communicating signals

Abstract

There is provided mechanisms for adapting which beam to use for communicating signals. A method is performed by a radio transceiver device. The radio transceiver device is capable of communicating thesignals using beams selected from a set of beams. The method comprises communicating signals with another radio transceiver device while using a first beam selected from the set of beams. The methodcomprises detecting that the signals are communicated at decreasing quality level while using the first beam. The decreasing quality level is caused by radio propagation channel deterioration. The method comprises, in response thereto, initiating a switch to a backup beam of the first beam, without performing any beam training, to continue communicating the signals with said another radio transceiver device, thereby adapting which beam to use for communicating the signals.

Description

technical field

[0001] Embodiments presented herein relate to a method, a radio transceiver device, a computer program, and a computer program product for which beam is adapted for transmitting a signal. Background technique

[0002] In communication networks, it can be challenging to obtain good performance and capacity for a given communication protocol, its parameters, and the physical environment in which the communication network is deployed.

[0003] For example, for future generations of mobile communication systems, frequency bands at many different carrier frequencies may be required. For example, low such frequency bands may be required to achieve adequate network coverage for end devices, and higher frequency bands (e.g. at millimeter wavelength (mmW), i.e. near and above 30 GHz) may be required to achieve the required network capacity . Generally speaking, at high frequencies, the propagation characteristics of the radio channel are more challenging and beamfor...
