11. A method comprising:
receiving, by a user device from a network node, a configuration including at least an indication to perform spectrum extension;
determining, by the user device, a target extension factor for excess band frequency resources for a target spectrum extension;
receiving, by the user device from the network node, information indicating a set of inband frequency resources allocated to the user device for uplink transmission;
determining, by the user device based on the set of inband frequency resources and the target extension factor, the excess band frequency resources for the spectrum extension and a total allocation of frequency resources for uplink transmission, wherein the total allocation of frequency resources includes the inband frequency resources and the excess band frequency resources;
performing, by the user device, a spectrum extension based on the excess band frequency resources for a set of frequency domain values, to obtain a spectrum extended signal;
determining, by the user device, that the excess band frequency resources include an odd number of resource blocks or one or more orphan resource elements that are part of a fractional resource block;
shifting, by the user device, the total allocation including the inband frequency resources and the first half and the second half of the excess band frequency resources, by one half of a resource block in the frequency domain so that the resource blocks of the total allocation are resource block aligned with a grid of resource blocks; and
transmitting the spectrum extended signal.
