Abstract: The disclosure describes configuration schemes for secondary cell (SCell), bandwidth part (BWP) and physical resource block (PRB) indexing. An apparatus of user equipment (UE) for BWP activation and deactivation operation is disclosed. The apparatus includes baseband circuitry that includes a radio frequency (RF) interface, and one or more processors. The one or more processors are to receive radio resource control (RRC) data via the RF interface, configure a timer for a BWP according to the RRC data, and trigger the timer for the BWP in response to detection of an event associated with an access node after the BWP has been activated.

Abstract: Systems and methods are provided for increasing paging opportunities when the unlicensed band is used. A user equipment (UE) may determine a plurality of different paging occasions (POs) to monitor per DRX cycle. The plurality of different POs corresponds to beam sweep repeats for a first set of UEs in an unlicensed band from a base station in a wireless network. The UE monitors the plurality of different POs to receive the paging message from the base station. The plurality of different POs may include respective physical downlink control channel (PDCCH) monitoring occasions. The plurality of different POs may include at least two consecutive POs associate with the first set of UEs within a same paging frame. Alternatively, the plurality of different POs may include at least two non-consecutive POs associated with the first set of UEs separated by at least cycle one other PO associated with a second set of UEs.

Abstract: An approach is described for a method for a fifth generation (5G) wireless communication or a new radio (NR) system that includes the following steps. The method includes generating data samples associated with a sampling rate. The method further includes generating a waveform by populating a first slot and a second slot in a subframe of the waveform using the data samples, wherein slot durations of the first slot and the second slot in the subframe of the waveform equal respective durations of a first slot and a second slot in a subframe of a reference waveform to thereby align the first slot and the second slot in the subframe of the waveform with the respective first slot and second slot in the subframe of the reference waveform. The method further includes transmitting the waveform using front end circuitry, wherein the waveform is a single carrier waveform, and wherein the reference waveform is an orthogonal frequency division multiplexing (OFDM) waveform.

Abstract: Techniques discussed herein can facilitate reduced frequency of triggering a RLF (Radio Link Failure) timer and/or a false RLF procedure via employing one or more mechanisms for associating BFR (Beam Failure Recovery) and RLF. A first mechanism that can be employed in various embodiments can perform one or more RLF-related actions (e.g., stopping a T310 timer, resetting a N310 counter) upon BFR success. A second mechanism that can be employed in various embodiments can comprise revising one or more RLF parameters (e.g., N310, N311, T310, Out-of-sync threshold, in-sync threshold, etc.) based on the presence of a strong BFR mechanism.

Abstract: Some embodiments of this disclosure include apparatuses and methods for physical downlink control channel design for a discrete Fourier Transform-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) waveform. The apparatuses and methods can include at least operating a base station (BS) to generate one or more physical downlink control channels (PDCCH) in a time division multiplexing (TDM) manner using a Discrete Fourier Transform-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) waveform, generate a demodulation reference signal (DMRS) which is multiplexed in the TDM manner with the one or more PDCCH, and transmit the one or more PDCCH and the DMRS to a user equipment (UE).
