Embodiment Construction

[0065] As part of the development of the embodiments herein, one or more problems with the prior art will first be identified and discussed.

[0066] As mentioned earlier, NR was developed after NB-IoT had been standardized. Therefore, currently there is no method for regulating or handling the coexistence of NB-IoT and NR.

[0067] One possible way to achieve the deployment of Narrowband Internet of Things (NB-IoT) carriers may be through reconfiguration. That is, several narrower carriers can be turned off and the bandwidth can be used for wideband systems. One problem after reconfiguration is that operators may still need to provide services to legacy UEs. NB-IoT UEs can be expected to have a life cycle of 10 years or more. Therefore, a solution can be to reserve some small bandwidth at the band edge of the NB-IoT system to avoid the obstruction of the traditional system. However, the limitation here is that it is difficult to expand the NB-IoT system in the future. An...

Abstract

A method performed by a first network node (111) operating in a wireless communications network (100) is described herein. The first network node (111) initiates (702) sending a first indication to afirst wireless device (131) operating in the wireless communications network (100) using NB-IoT. The first indication indicates that a first carrier (141), and the first carrier (141) is a standalonenarrow band-internet of things, NB-IoT, carrier operating within a new radio, NR, carrier, is a) deployed in one of a guardband mode and an inband mode, and b) shifted away by a frequency offset froma frequency channel raster grid used by the first wireless device (131).

Description

technical field [0001] The present disclosure generally relates to a first network node and a method performed thereby for handling carriers in a wireless communication network. The present disclosure also generally relates to a second network node and a method performed by it for handling carriers in a wireless communication network. The present disclosure further generally relates to a first wireless device and a method performed thereby for handling carriers in a wireless communication network. The present disclosure further relates generally to computer programs and computer-readable storage media having stored thereon the computer programs for performing these methods. Background technique [0002] A communication device within a wireless communication network may be a wireless device such as, for example, a user equipment (UE), a station (STA), a mobile terminal, a wireless terminal, a terminal and / or a mobile station (MS). A wireless device is capable of communicati...
