Embodiment Construction

[0039]The inventive concept will now be described more fully hereinafter with reference to the accompanying drawings, in which certain embodiments of the inventive concept are shown. However, inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of illustration so that this disclosure will be thorough and complete, and will The scope of the inventive concept fully conveys to those skilled in the art. Like numbers refer to like elements throughout the specification. Any steps or features indicated by dashed lines should be considered optional.

[0040] Single-tone frequency-hopping NB-IoT PRACH (labeled NPRACH) signals have low PAPR, so using NPRACH reduces the need for PA backoff and maximizes PA efficiency. The NPRACH signal is compatible with SC-FDMA and Orthogonal Frequency Division Multiple Access (OFDMA), because in any OFDM symbol interval, the...

Abstract

A communication network is accessed by wireless devices associated with an overlay class selected from a set of overlay classes. The wireless device performs a method comprising initiating pairing by transmitting a preamble for random access on a physical random access channel during an initiation opportunity defined by the coverage class of the wireless device. network access to the communication network. Each override class can be associated with a unique number of repetitions of the preamble sequence transmission.

Description

technical field [0001] Embodiments presented herein relate to a method, a wireless device, a computer program and a computer program product for network access of a communication network by a wireless device. Further embodiments presented herein relate to a method, a network node, a computer program and a computer program product for enabling network access of a wireless device to a communication network. Background technique [0002] In communication networks, it is 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] For example, evolved services are associated with new requirements of cellular networks, eg regarding device cost, battery life and coverage. To reduce device and module costs, a system-on-chip (SoC) solution with an integrated power amplifier (PA) can be used. However, current state-of-the-art PA technologies allow transmi...
