Abstract

There is provided mechanisms for signal transmission diversity at an antenna array of a radio transceiver device. The antenna array has two physical antenna ports. A method is performed by the radio transceiver device. The method comprises creating two virtual antenna ports for each of the two physical antenna ports, resulting in four virtual antenna ports. The method comprises transmitting the signal from the four virtual antenna ports towards another radio transceiver device over four different radio propagation channels, one radio propagation channel per virtual antenna port.

Description

technical field [0001] Embodiments presented herein relate to a method for signal transmission diversity at an antenna array of a radio transceiver device, a radio transceiver device, a computer program and a computer program product. Background technique [0002] In a communication network, 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, 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 sufficient network coverage for terminal devices and higher frequency bands (eg, at millimeter wavelength (mmW), ie near and above 30 GHz) may be required to achieve the required network capacity. In general, at high frequencies, the propagation nature of the radio channel is more challen...
