[0041] Tone hopping NB-IoT PRACH (designated 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 N...

Abstract

The embodiment of the invention relates to a method and apparatus for network access of a wireless device to a communication network. A communication network is accessed by a wireless device associated with a coverage class selected from a set of coverage classes. The wireless device performs a method that includes initiating network access to the communication network by transmitting a preamble sequence for random access on a physical random access channel during an initiation opportunity defined by the coverage class of the wireless device. Each coverage class may be associated with a unique number of repetitions of the preamble sequence transmission.

Description

[0001] This application is a divisional application of a patent application filed on March 10, 2017 with the application number of 201780017454.1 and the name of the invention as "Network Access to Communication Networks by Wireless Devices". technical field [0002] The embodiments presented herein relate to a method, wireless device, computer program and computer program product for network access of a wireless device to a communication network. Further embodiments presented herein relate to a method, network node, computer program and computer program product for enabling network access of a wireless device to a communication network. Background technique [0003] In a communication network, it is challenging to obtain good performance and capacity for a given communication protocol, its parameters and the physical environment in which the communication network is deployed. [0004] For example, evolved services are associated with new requirements for cellular networks, ...
