Power headroom of grantless uplink

Abstract:

Embodiments herein are related to grantless uplink control information (G-UCI) content and size designs/mechanisms in MulteFire (MF) systems. Since the power control of the grantless uplink (GUL) use is different from the scheduled uplink (SUL), the power headroom (PHR) calculation and reporting should be enhanced. Embodiments herein provide an electronic apparatus employed in an user equipment (UE). The electronic apparatus comprises a radio frequency (RF) circuitry interface and processing circuitry. In an example, the processing circuitry is configured to calculate the PHR of the GUL physical uplink shared channel (PUSCH); generate an uplink data including the PHR of GUL.
