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 eg to a method performed by a radio network node (12) for handling system information of a wireless communication network. A radio network node receives a request from a wireless device (10) to transmit at least a part of system information, wherein the request is associated with an indication that the request is for transmission of at least a part of system information. The radio network node further sends the requested at least part of the system information to the wireless device in transmission, wherein one or more characteristics of the transmission are adapted based on the received request; wherein the transmission is beamformed towards the wireless device and / or Transfers are performed in intervals from the time the request is received.

Description

technical field [0001] Embodiments herein relate to radio network nodes, wireless devices, and methods performed therein. Furthermore, computer program products and computer-readable storage media are provided herein. In particular, embodiments herein relate to enabling communication of wireless devices, eg, 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 (STAs) and / or user equipments (UEs)) via a radio access network to one or more core networks (CNs) (RAN) to communicate. The RAN covers a geographic 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 controlled by a radio access node such as a Wi-Fi access point or a radio base station ( RBS)), which may also be denoted eg NodeBs, eNo...
