Embodiment Construction

[0040] For purposes of simplicity and illustration, the present disclosure will be described primarily with reference to exemplary embodiments thereof. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be apparent, however, to one skilled in the art that the present disclosure may be practiced without these specific details. In this specification, well known methods and structures have not been described in detail so as not to unnecessarily obscure the disclosure.

[0041] Figure 1a A first wireless communication system and a second wireless communication system are shown, eg served by one or more first and second network nodes which may be the same or different network nodes. A first wireless communication system (eg, a Narrowband Internet of Things (NB-IoT) system) is deployed on one or more frequency resources including frequency resource 145 . In one example, the frequenc...

Abstract

Embodiments herein relate to a method performed, for example, by a wireless device in a first wireless communication system deployed on a frequency resource. The wireless device receives information indicative of PRB offsets and corresponding channel grid offsets. The channel grid offset is the frequency offset between the channel grid and frequency resources used by the wireless device (105) during the cell search process. The PRB offset indicates an offset between frequency resources and internal frequency resources deployed with the second wireless communication system. In the frequency domain, the second wireless communication system is deployed on at least one higher frequency resource higher than the internal frequency resource and at least one lower frequency resource lower than the internal frequency resource. Based on the received information, the wireless device determines a frequency adjustment applicable to frequency resources deployed with the first wireless communication system.

Description

technical field [0001] The present disclosure relates generally to the field of communication, and in particular to a wireless device, a network node and a method performed in a first wireless communication system. In addition, computer programs and computer readable storage media are also provided herein. Background technique [0002] The Background section of this document is provided to put the embodiments of the disclosure into a technical and operational context, to assist those skilled in the art in understanding their scope and utility. Unless expressly stated otherwise, no statement herein is admitted to be prior art by inclusion in the Background section. [0003] Cellular communication systems are currently being developed and improved for Machine Type Communication (MTC), a type of communication characterized by lower data rate requirements than e.g. Range and the ability to use the battery for years without recharging or replacing the battery have higher demand...
