Abstract: Systems, devices, and techniques for user equipment (UE) power control are described. A described technique includes receiving, by a UE, a discontinuous receiving (DRX) configuration from a base station; monitoring, by the UE on a physical downlink control channel (PDCCH), for downlink control information (DCI) messages outside of a DRX active time, the DCI messages being of a predetermined format that is configured to provide wake-up signaling; receiving, by the UE, a DCI message outside of the DRX active time, the DCI message being of the predetermined format; and determining, by the UE, whether to wake-up based on the received DCI message.

Abstract: Embodiments are provided for resource monitoring and power saving in a user equipment (UE) operating according to a discontinuous reception (DRX) in new radio (NR) wireless communication system. The UE, operating in the DRX mode, monitors for a wake up occasion in control signal prior to the DRX ON time. If the wake occasion is detected, then the EFE monitors for a channel state information (CSI) resource signal (RS) prior to the DRX ON time. If no wake up occasion is detected, then at least a portion of the UE remains in a sleep mode prior to DRX ON time.

Abstract: This disclosure describes methods, systems, and devices for broadcasting a Physical Downlink Control Channel-based (PDCCH-based) wake-up signal. In one example, a method involves receiving, by one or more user equipment (UEs), a configuration for monitoring a wake up signal (WUS). The method further includes monitoring, by the one or more UEs and based on the configuration, a physical downlink control channel (PDCCH) for downlink control information (DCI) associated with the WUS. The method also includes receiving, by the one or more UEs, the WUS in response to detecting the DCI.

Abstract: Some embodiments of this disclosure include apparatuses and methods for a signaling mechanism for user equipment (UE) assistance feedback in a wireless communication system. At least a radio frequency integrated circuit can be configured to receive a first configuration signal, and transmit a first message comprising a UE assistance feedback, generated based on the first configuration signal, in an uplink (UL) channel. The first message can contain an index of a profile with information on a service requirement, a traffic characteristic, or a combination thereof of a network. A processor, coupled to the radio frequency integrated circuit, can be configured to generate the UE assistance feedback based on the first configuration signal.

Abstract: A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode radio resource control (RRC) signaling to obtain a cyclic shift value in time domain. The cyclic shift value is associated with a demodulation reference signal (DM-RS) antenna port (AP) of a plurality of available DM-RS APs. A single carrier based waveform DM-RS sequence corresponding to the DM-RS AP is generated using a base sequence and the cyclic shift value. The single carrier based waveform DM-RS sequence is encoded with uplink data for transmission to a base station using a physical uplink shared channel (PUSCH) using a carrier above the 52.6 GHz carrier frequency.
