Abstract: A system, method, and apparatus is provided for performing carrier aggregation (CA) radio resource management (RRM). The system, method, and apparatus can receive a configuration message having configuration information from an access node; determine a measurement period for a secondary cell (SCell) and a cell identification delay based upon the configuration information; identify a new detectable cell on a secondary component carrier (SCC) as the SCell within the cell identification delay; perform a measurement for a CA operation within the measurement period; and report the measurement to the access node. The configuration message can be a Radio Resource Control (RRC) message. The measurement for the CA operation can be a measurement of the SCell on the SCC. The system, method, and apparatus can multiply a measurement control parameter by a factor less than five (5) to determine the measurement period and can multiply a measurement control parameter by a factor less than twenty (20) to determine the cell identification delay. The system, method, and apparatus can further perform an action with respect to the SCell in response to the measurement.

Abstract: Various embodiments herein describe solutions to issues in beam switching for intra-band non-contiguous carrier aggregation. For example, the UE may interrupt downlink communication on one or more component carriers when the UE switches the receive beam with intra-band non-contiguous carrier aggregation. Other embodiments may be described and claimed.

Abstract: The present disclosure is directed to systems and methods for determining a starting point of a measurement gap. For example, the present disclosure is directed to a user equipment (UE) that includes a memory and processor circuitry coupled to the memory. The processor circuitry may be configured to receive an indication of a measurement gap timing advance. The processor circuitry may be further configured to, based on the indication of the measurement gap timing advance, determine a starting point of a measurement gap in a dual connectivity mode that provides dual connectivity with a new radio (NR) and an evolved universal mobile telecommunications system terrestrial radio access (EUTRA). The NR may serve as a master Radio Access Network (RAN) and the EUTRA may serve as a secondary RAN. The processor circuitry may also be configured to perform a signal quality measurement during the measurement gap, wherein the signal quality measurement is performed on a target cell of the NR or EUTRA.

Abstract: This disclosure provides techniques for activation of a secondary cell by a user equipment (UE) operating in a wireless network. For example, a UE receives a command to activate a secondary cell of the wireless network for wireless communication, and determines whether timing information is known by the UE for the secondary cell. Based on the determination, the UE performs a first secondary cell activation within first time period based on the timing information being known, or performs a second secondary cell activation within a second time period based on the timing information being unknown. After which, the UE wirelessly communicate data over the wireless network using the secondary cell, based on the secondary cell being activated.

Abstract: A method for enhanced autonomous uplink timing adjustment includes determining that a user equipment (UE) is traveling above a predetermined velocity. In response to the determination that the UE is traveling above the predetermined velocity, a maximum aggregate adjustment rate to an uplink timing for the UE and a maximum amount of a magnitude of a timing change to the uplink timing for the UE are determined. The uplink timing for the UE is adjusted based on the maximum aggregate adjustment rate and the maximum amount of the magnitude of the timing change.
