Abstract

There is provided mechanisms for configuration of physical antenna ports. The method is performed by a first radio transceiver device. A method comprises determining a configuration for the second radio transceiver device. The configuration defines a mapping between the sub-carriers and the physical antenna ports and specifies which of the sub-carriers are to be transmitted on which physical antenna port at the second radio transceiver device. The method comprises providing the configuration to the second radio transceiver device.

Description

technical field [0001] Embodiments presented herein relate to methods, radio transceiver devices, computer programs and computer program products for configuring physical antenna ports. 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] In communication networks, the constant pursuit of higher data rates has resulted in communication systems employing ever higher bandwidths. Because for a given total transmit power, the power spectral density (PSD) typically decreases with increasing bandwidth, this can create challenges for end devices to achieve the required link budget. This can be especially challenging for the higher frequency bands considered for so-called fifth-generation telecommunications systems, collectively referred to as 5G, because of the high path loss and...
