Problems solved by technology

The general use of this robust coding means that for the regular case (i.e., regular wireless devices and / or wireless devices with better channel conditions than cell edges, e.g. wireless devices closer to radio network node antenna sites, Encoding is too robust for wireless devices), SI transmission is unnecessarily large overhead and resource usage

Abstract

Embodiments herein relate to e.g. a method performed by a radio network node (12) for handling system information of a wireless communication network. The radio network node receives, from a wirelessdevice (10), a 5 request for transmission of at least a part of the system information, wherein the request is associated with an indication indicating that the request is for a transmission of the atleast part of the system information. The radio network node further transmits, in a transmission, the requested at least part of the system information to the wireless device, wherein one or more properties of 10 the transmission are adapted based on the received request; and wherein the transmission is beam-formed towards the wireless device and / or the transmission is performed within a time interval from the received request.

Description

technical field [0001] Embodiments herein relate to radio network nodes, wireless devices and methods performed therein. Additionally, computer program products and computer-readable storage media are provided herein. In particular, embodiments herein relate to enabling, for example, communication of wireless devices processing system information in a wireless communication network. Background technique [0002] In a typical wireless communication network, wireless devices (also referred to as wireless communication devices, mobile stations, stations (STA) and / or user equipment (UE)) communicate via a radio access network to one or more core networks (CN) (RAN) to communicate. The RAN covers a geographical area and provides radio coverage over service areas or cells, which may also be referred to as beams or beam groups, where each service area or beam is composed of, for example, radio access nodes (e.g. Wi-Fi access points or radio base stations ( RBS)) are served or co...
