Abstract: Various communication systems may benefit from improved signaling. For example, it may be helpful to improve the management of the uplink timing alignment where multiple numerologies are used. A method may include receiving at a user equipment an indication from a network node. The timing adjustment granularity may be determined implicitly based on one or more multiple numerology assigned to a timing advance group. The method may also include applying at the user equipment the indicated timing adjustment granularity associated with one of the multiple numerologies.

Abstract: Embodiments of the present disclosure relate to controlling a control resource set (CORESET) #0 puncturing. Some embodiments comprise determining, at a first apparatus, based at least on detection of a synchronization signal block, received from a second apparatus, on a specific frequency location, whether a CORESET of a specific type is punctured, wherein a portion of resources punctured in the CORESET of the specific type are incapable of carrying downlink control information; in accordance with a determination that the CORESET of the specific type is punctured, obtaining a CORESET puncturing pattern; and determining the portion of resources punctured in the CORESET at least based on the CORESET puncturing pattern. Furthermore, the method comprises indicating, from a second apparatus to a first apparatus, that a CORESET of a specific type is punctured by transmitting a synchronization signal block on a specific frequency location.

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 search space configuration for multi-slot physical downlink control channel (PD-CCH) monitoring scenarios. A method may include determining that a search space relates to a subcarrier spacing and to multi-slot physical downlink control channel monitoring. The method may also include receiving configuration for a number of X slots in a slot group and a number of Y slots with monitoring occasions, and a location of Y slots within a slot group of X slots. The method may further include receiving a first configuration for a given physical downlink control channel search space. In addition, the method may include monitoring a physical downlink control channel corresponding to the search space based on values of X and Y.
