Abstract: A network device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component) can process or generate a dynamic indication that indicates a transmission bandwidth based on a wideband bandwidth. One or more downlink (DL) signals can be provided with the indication of the transmission bandwidth that enables a tuning of communications within the wideband bandwidth based on the indication for new radio (NR) communications in heterogeneous network domains ranging from Enhanced Mobile Broadband (eMBB) to massive Machine-Type Communications (mMTC) and Ultra-Reliable Low-Latency Communications (URLLC) or the like.

Abstract: Methods, apparatus, and systems are provided for signalling transmissions using carriers of different numerologies. In one example, a baseband processor of a base station is configured to perform operations including encoding a first signal to be transmitted on a physical downlink control channel (PDCCH) on a first component carrier with a first subcarrier spacing. The first signal includes downlink control information (DCI) indicating resources for a second signal to be transmitted on a second component carrier with a second subcarrier spacing. Respective numerologies of the first component carrier and the second component carrier are different from one another in accordance with the first subcarrier spacing and the second subcarrier spacing. The baseband processor is configured to cause transmission of the first signal on the PDCCH.

Abstract: Systems and methods of initial acquisition in a NR system are described. A UE receives time and frequency superposed SSBs from a gNB. If the PSS and SSS of each SSB is independent of a block index of the SSB, the UE receives an additional reference signal scrambled by a beam index of the SSB and uses the reference signal to discriminate between the SSBs. The reference signal is FDMed within a null-subcarrier region of the SSB or outside of the SSB. If the PSS and SSS of each SSB is scrambled using the block index, the UE separates the PBCH measurements, iteratively identifies a block index associated with a DMRS of the PBCH with the highest L1-RSRP level measurement, decodes and reconstructs the PBCH, and subtracts the reconstructed PBCH from the SSB before transmitting an indication of the PBCH with the highest L1-RSRP level measurement to the gNB.
