Abstract

There is provided mechanisms for performing beam management. A method is performed by a radio transceiver device. The method comprises transmitting a reference signal in a transmission beam as part ofthe beam management. The reference signal in the transmission beam occupies time / frequency resources that extend over a frequency interval. The transmission beam has a frequency-dependent polarization over the frequency interval.

Description

technical field [0001] Embodiments presented herein relate to a method, a radio transceiver device, a computer program and a computer program product for performing beam management. Embodiments presented herein also relate to a method, a radio transceiver device, a computer program and a computer program product for participating in beam management. Background technique [0002] In communication networks, it can be challenging to achieve 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, many bands of different carrier frequencies may be required for future generations of mobile communication networks. For example, low such frequency bands may be required to achieve adequate network coverage for wireless devices, and higher frequency bands (e.g., at millimeter wavelength (mmW), ie near and above 30 GHz) may be required to achieve the required ne...
