Problems solved by technology

However, from the perspective of a client device (such as a UE) that needs to monitor broadcasted signals from the transmitting AN (or network node), it implies a relatively large power consumption to monitor these broadcasted signals, since the client device may The transmitted signal needs to be decoded multiple times until the transmitted signal is detected or the scan interval ends

Embodiment Construction

[0038] In the following description, different embodiments of the exemplary embodiments will be described in more detail with reference to the accompanying drawings. For purposes of explanation and not limitation, specific details are set forth, such as specific examples and techniques, in order to provide a thorough understanding.

[0039] The present disclosure relates to the transmission of broadcast messages, including system information and paging messages, using configured or predefined scanning patterns that have specific relative timing and / or frequency associations relative to transmitting pilot messages using beam scanning patterns. Since the scanning pattern for paging messages may be predefined or configured, a UE or access node (hereafter referred to as UE) may derive the timing and / or frequency window in which beams carry broadcast messages directed to the UE.

[0040] Therefore, the UE may know in which timing and / or frequency window to transmit the broadcast me...

Abstract

A network node (600; 700), a client device (800; 900) and methods therein are disclosed for transmitting and receiving broadcasted messages utilizing beam scan patterns associated with each other. A client device with information about the association between the first and second beam scan patterns can determine when and where to monitor for the receipt of a paging message based on the receipt of the pilot message. This provides power efficiency improvements for UEs when monitoring broadcasted messages transmitted in scan mode.

Description

technical field [0001] The present disclosure relates to broadcast transmission and reception. More specifically, it relates to a network node, a client device and a method therein for broadcasting a message and receiving said broadcasted message, respectively. Background technique [0002] Fifth generation (5G) mobile networks may be a combination of evolved third generation (3G) technologies, fourth generation (4G) technologies and emerging or substantially new components such as Ultra Density Networks (UDNs), They are also known as millimeter wave (mmW) radio access types (RATs). [0003] Due to the increasing demand for enhanced capacity in wireless networks and the lack of spectrum availability in the frequency range (eg 800 MHz-3 GHz), the use of frequencies in the tens of GHz range is being investigated. Research is ongoing to develop high frequency bands in eg the 30 GHz, 60 GHz and 98 GHz range for mobile network purposes. At these frequencies, a large spectral b...
