Claim 11:
12. A non-transitory computer readable medium having stored thereon a set of computer readable instructions that, when executed by at least one processor, cause an apparatus to at least:
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.
