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, methods, and circuitries are provided for configuring and indicating channel state information resource signals (CSI-RS) using discovery reference signal (DRS) resources. An example method includes determining discovery reference signal (DRS) resources for use in carrying channel state information reference signals (CSI-RS); generating CSI-RS configuration information that defines at least one CSI-RS using the DRS resources; and signaling the CSI-RS configuration information to a user equipment (UE) device.

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: One or more computer-readable media (CRM) are disclosed. The CRM include instructions to, upon execution of the instructions by one or more processors of a base station, cause the base station to: generate a phase tracking reference signal (PT-RS) for phase shift compensation; and transmit the PT-RS across a physical downlink shared channel (PDSCH) using a single-carrier based waveform comprising a carrier frequency. The single-carrier based waveform may be SC-FDE or DFT-s-OFDM.

Abstract: Some embodiments of this disclosure include apparatuses and methods for supporting integrated access and backhaul (IAB) networks. IAB nodes may be configured to broadcast in-raster and off-raster synchronization signal blocks (SSBs) for establishing communications with mobile devices and/or user equipment (UE). The SSBs may provide control resource set (CORESET) data used for establishing a communication channel between a UE and an IAB node. The CORESET data may be configured to support the broadcast of off-raster SSBs in wireless communication systems. In some embodiments, the in-raster SSB and the off-raster SSB may share the same CORESET. In this case, the IAB may modify a bit pattern of configuration table corresponding to the shared CORESET and broadcast the in-raster SSB and the off-raster SSB while including the modified bit pattern.

Abstract: Methods and apparatus are described for methods and apparatus for carrying out wireless communication using Long Term Evolution (LTE) in a frequency band with low peak-to-average-power. The approach includes precoding, in the frequency domain, a plurality of physical channel signals, followed by multiplexing, where the procoding is performed according to predetermined codes with a code length selected based on a length of an entire signal of the multiplexed precoded plurality of physical channel signals. In addition, the approach includes being configured to map the multiplexed precoded plurality of physical channel signals to subcarriers in the frequency band, as well to generate a time domain waveform based on the mapped signals.
