Abstract: Systems and methods for implementing uplink (UL) gaps to facilitate user equipment (UE) calibration are disclosed herein. A UE determines one or more slot patterns of a slot configuration that is repeated during time division duplex (TDD) communication with a base station. The UE determines a UL gap periodicity (defining periods covering an integer number of repetitions of the slot configuration). The UE then performs UE calibration during one or more semi-persistently configured UL slots of a period of the UL gap periodicity that correspond to UL indication(s) in one or more of a common configuration, a dedicated configuration, and/or a slot format indication (SFI) downlink control information (DCI) for the slot pattern(s) of the slot configuration. Methods of identifying particular semi-persistently configured UL slots of a period to use for the UL gap are also discussed. UL slot indications from dynamic DCI are not used for UL gap purposes.

Abstract: Provided is a method for a user equipment (UE). The UE obtains a physical uplink control channel (PUCCH) secondary cell (SCell) activation command from a primary cell (PCell) or primary secondary-cell-group cell (PSCell). The PUCCH SCell activation command is used for an PUCCH SCell activation of a target PUCCH SCell for the UE. The UE performs PUCCH SCell activation operations associated with a valid timing advance (TA) and the PUCCH SCell activation command. TA is considered to be a valid TA when the TA meets a preset criterion. The UE generates a channel state information (CSI) report for transmission to at least one of the PCell, PSCell and the target PUCCH SCell. The CSI report indicates that the PUCCH SCell activation is completed.

Abstract: Techniques discussed herein may better ensure efficient fine time tracking during a second cell (SCell) activation procedure by using a tracking reference signal (TRS) that is User Equipment (UE) specific. A primary cell (PCell) may provide a UE with a TRS configuration that includes a UE-specific reference signal (RS) with aperiodicity. In response to receiving a SCell activation command from the PCell, the UE may perform cell activation in accordance with the UE-specific RS. As the delay time for the UE-specific RS may be less than the delay time for a system synchronization block (SSB) from the SCell, use of the UE-specific RS may expedite the cell activation procedure.
