Embodiment Construction

[0073] Embodiments herein may refer to GNSS, RTK, positioning, SIB.

[0074] figure 2Logical entities of a wireless communication network are schematically shown in more general terms. A target device or UE 10, 120 is an entity that performs positioning measurements supported by a positioning assistance data element broadcast by a radio network node (RNN) in a SI message as a positioning SIB (pSIB), said radio network node ( RNNs) are typically radio base stations 20, 110, but in even more general terms transmission points, radio heads, cell eNBs, gNBs, etc. The broadcast information is prepared by a network node (NN) 30, 132, which may be a location server, an enhanced service mobile location center (E-SMLC), a location management function (LMF), etc. Optionally, the location assistance data for broadcast may be encrypted / encrypted at the NN 30, 132, in which case the decryption / decryption key is sent from the NN 30, 132 to the Mobility Network Node (MNN) 40, 130. The MN...

Abstract

A wireless device 10,120 and a method performed therein for receiving scheduled positioning system information from a radio network node 20, 110. The wireless device and the radio network node operatein a wireless communications network 100. The wireless device receives, from the radio network node, positioning system information scheduling information (pSI) and at least one out of a scheduling offset and a number of system information messages with positioning system information blocks (pSIMs) per system information (SI) window. Further, the wireless device determines in which subframes oneor more pSIMs are scheduled by the radio network node based on the pSI and based on at least one out of the scheduling offset and the number of pSIMs per SI window. Furthermore, the wireless device uses the determined scheduling of the one or more pSIMs for receiving the one or more pSIMs.

Description

technical field [0001] Embodiments herein relate to radio network nodes, wireless devices and methods therein. In particular, embodiments relate to scheduling of positioning system information blocks (SIBs). Background technique [0002] In a typical wireless communication network, wireless devices, also known as wireless communication device, mobile station, station (STA) and / or user equipment (UE). The RAN covers a geographical area divided into service areas or cell areas, which may also be referred to as beams or beam groups, where each service area or cell area is served by a radio network node, such as a radio access node, which An access node such as a Wi-Fi access point or a radio base station (RBS), which in some networks may also be denoted as NodeB, eNodeB (eNB) or gNB as denoted eg in 5G. A service area or cell area is a geographical area in which a radio network node provides radio coverage. The radio network node communicates with wireless devices within ra...
