Abstract: A method is performed by user equipment (UE) for communicating on a secondary cell (SCell) with fast activation or deactivation. The method includes receiving, from a serving cell, a medium access control (MAC) control element (CE) including a plurality of bits, wherein individual bits of the plurality of bits each indicate whether respective secondary cells (SCells) of a fifth generation (5G) wireless cellular network are activated or deactivated. The method includes based on a numerology of the serving cell, determining an activation delay time for one or more activated SCells indicated by the plurality of bits of the MAC CE. The method includes communicating using the one or more activated SCells based on the determined activation delay time.

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: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for configuring and implementing secondary cell beam failure recovery procedures. For example, some embodiments are directed to a user equipment (UE) that includes radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry can be configured to detect that a first beam associated with a secondary cell (SCell) is misaligned. The first beam is associated with a first reference signal (RS). The processor circuitry can further be configured to configure a beam failure recovery (BFR) procedure for the SCell and perform the BFR procedure to replace the first beam with a second beam, wherein the second beam is associated with the SCell.

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.
