Abstract: A Phase Tracking Reference Signal (PTRS) configuration for signal-carrier waveforms (e.g., Known Tail Discrete Fourier Transform (DFT) spread Orthogonal Frequency Division Multiplexing (KT-DFT-s-OFDM) or Single Carrier Frequency Domain Equalization (SC-FDE) waveforms) used in a communication network. For this purpose, a configurable-length sequence of modulation symbols is added in the beginning and end of each single-carrier waveform symbol. One or more sequences of modulation symbols are reported to a User Equipment (UE) from a network node. The PTRS configuration is defined at the UE based on the sequence length(s) and indicative of how PTRS mapping is to be performed within each single-carrier waveform symbol. The UE may then perform communications with the network node using the PTRS configuration. With such PTRS configuration, it is possible to efficiently perform phase noise detection and compensation.

Abstract: Systems, methods, apparatuses, and computer program products for filter power distribution indication. A method may include determining a first size of a first part of a frequency band segment within a total bandwidth allocation, and a second size of a second part of the frequency band segment. The method may also include determining a value indicative of a power spectral density difference or power difference between the first part and the second part. The method may further include generating a power indication of the frequency band segment within the total bandwidth allocation based on the power spectral density difference. In addition, the method may include signaling, to a network element, the power indication for the frequency band segment within the total bandwidth allocation.

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.
