Claim 10:
11. A radio network node for handling communication in a wireless communications network, the radio network node is configured to:
receive from a user equipment, UE, a first indication in a power headroom report, PHR, of a serving cell, the first indication indicates presence of a first type of power headroom, PH, of a first carrier in the PHR of the serving cell and the first type is referring to an uplink reference signal, RS, transmission power, and the PHR of the serving cell further comprises a second indication indicating presence of a PH of a second type of a second carrier of the serving cell, wherein the second type is referring to a user data transmission power; and
estimate a transmission power status of the UE based on one or both of the first and second type of the PH in the PHR of the serving cell, the first indication and the second indication are in a preconfigured order in the PHR of the serving cell, the UE is configured by the radio network node such that the first carrier is a new radio uplink carrier and the second carrier is a supplementary uplink, SUL, carrier and are placed in a fixed order regardless of physical uplink shared channel, PUSCH, and a placement order of PH is determined based on a type of the carrier, in which a PH triggered due to the transmission of the NR carrier is placed first, and a PH triggered due to the transmission on the SUL carried is placed second, and both of the first indication and the second indication are comprised in a subheader of a medium access control, MAC, control element, CE, with a reserved bit of the MAC subheader being used to indicate presence of a subsequent type 3 PH.
