Abstract: Systems, methods, apparatuses, and computer program products relating to phase tracking reference signal (PT-RS) design, for example, for discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM), are provided. One method may include forming, by a network node, a phase tracking reference signal (PT-RS) sample sequence using outer-most constellation points corresponding to scheduled modulation order of data channel, and scrambling the phase tracking reference signal (PT-RS) sample sequence with a user equipment-specific sequence.

Abstract: Various communication systems may benefit from new slot formats to support dynamic allocation between SC and CP-OFDMA. In accordance with some embodiments, a method may include transmitting, by a network entity, at least one physical downlink slot containing at least one physical downlink shared channel (PDSCH) and at least one physical downlink control channel (PDCCH). The at least one PDCCH is associated with at least one subcarrier waveform without a cyclic prefix (CP). The at least one PDSCH is associated with at least one CP-orthogonal frequency division multiplexing (OFDM) or single carrier (SC) waveform.

Abstract: In a first subframe, data is sent by a network node in a DL shared channel and a timing indicator is sent in a PDCCH to UE, the timing indicator indicating an offset relative to the first subframe the UE should use in order to determine a second subframe to use to send, in a PUCCH, acknowledgement information for the data received in the DL shared channel of the first subframe. The acknowledgement information is received by the network node from the UE in the PUCCH of the second subframe. The UE receives the data and timing indicator and determines the second subframe using at least the timing indicator. The UE transmits the acknowledgement information in the PUCCH of the second subframe. Apparatus, computer programs and products, and methods are disclosed.
