Abstract: A method, apparatus, and computer readable medium facilitate network control by allowing a base station to predict when power class fallback will occur in user equipment. In the context of a method, the method receives a message comprising information about at least one of a first power class or a maximum duty cycle associated with user equipment. The method determines, based on at least the first power class or the maximum duty cycle, a threshold duty cycle for the user equipment. The method causes the threshold duty cycle to be transmitted to the user equipment. The method determines an uplink transmission schedule for the user equipment based at least on the first power class or the maximum duty cycle. The method receives, from the user equipment, a report that the threshold duty cycle has been exceeded by the user equipment.

Abstract: Various techniques are provided for a method including receiving, at a network device from a user equipment (UE), an indication of a UE capability to support a per-band maximum power for a radio band combination (BC) used by the UE, determining whether the UE supports per-band maximum power for the radio BC based on the indication of the UE capability, and in response to determining the UE supports per-band maximum power for the radio BC, determining a total UE transmission power based on a sum of a maximum power of each band in the radio BC.

Abstract: Techniques of wireless communications include enabling the UE to indicate region in the channel bandwidth of a band combination where the MSD is zero or small. The indication defines a frequency boundary where MSD is “low” (e.g., small or zero dB) and MSD is “high” (e.g., >0 dB), and may contain a frequency offset from the centre of the MSD originating source to the boundary. The UE indication may be given as part of UE capabilities (e.g., UE indicates per BC the MSD region and MSD value within the region), or as a part of UE response to a network request (e.g., network requests UE to report MSD values for a given band combination and UE provides the information), with a UE capability for supporting such request-response mechanism.
