Abstract
The disclosure relates to methods and arrangements wherein a user equipment (UE) supporting a first frequency band HB is enabled to communicate with a network utilizing a second frequency band. The second frequency band is a sub-band of the first frequency band or overlaps with the first frequency band. The UE, which supports the first frequency band, implements 32 the channel numbering scheme of the second frequency band SB which overlaps with the first frequency band HB. This enables the UE supporting the first frequency band HB to recognize the second frequency band SB and communicate 33 with the network when the UE is camped or connected to a cell operating in the second frequency band SB.

A method implemented in a user equipment arranged to communicate with a network node in a cellular communication system, wherein the user equipment is configured to support a first frequency band and the method comprises:
- acquiring at least one parameter related to at least one second frequency band;
- determining the at least one second frequency band to which the acquired at least one parameter corresponds, wherein the at least one second frequency band comprises a sub-band of the first frequency band or overlaps with the first frequency band;
- implementing a channel numbering scheme related to the at least one second frequency band;
- and
- communicating with the network node on the at least one second frequency band.
A method implemented in a network node comprised in a cellular communication system, the network node arranged to communicate with a user equipment, wherein the user equipment is configured to support a first frequency band, the method comprising:
- receiving an indication from the user equipment that the user equipment is able to recognize a channel numbering scheme related to at least one second frequency band, wherein the at least one second frequency band comprises a sub-band of the first frequency band or overlaps with the first frequency band;
- determining if the at least one second frequency band is used in the network node;
- if the at least one second frequency band is used, the method further comprising:
- sending to the user equipment at least one parameter related to the at least one second frequency band;
- and
- communicating with the user equipment on the at least one second frequency band.
