Claim 0:
1. An apparatus comprising at least one processing core, at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to:
transmit information in a physical uplink shared channel direction using, selectably, a first waveform or a second waveform, the second waveform having lower peak to average power ratio than the first waveform;
provide, in response to a triggering condition being fulfilled in the apparatus, to a network node controlling a cell in which the apparatus is attached, first and second power headroom information, the first power headroom information disclosing a quantity of power between a maximum allowed or achievable transmit power and a first transmit power, currently used by the apparatus to transmit on the physical uplink shared channel using the first waveform, the second power headroom information disclosing a quantity of power between the maximum allowed transmit power, or a maximum achievable power using the second waveform, and a second transmit power that the apparatus would use to transmit on the physical uplink shared channel if the apparatus were using the second waveform;
select to either continue using the first waveform on the physical uplink shared channel, or to switch to using the second waveform on the physical uplink shared channel; and
the triggering condition comprises that a difference in power headroom between the first and second waveform changes in excess of a second threshold amount of change.
