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: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for scheduling intra-frequency measurements. Some embodiments are directed to a user equipment (UE). The UE includes processor circuitry and radio front circuitry. The processor circuitry can be configured to determine a collision signal status between an intra-frequency measurement signal and an uplink transmission signal. The processor circuitry can be further configured to determine a measurement gap status of the LIE. Moreover, the processor circuitry can be further configured to prioritize between the SSB measurement signal and the uplink transmission signal based on the collision signal status and the measurement gap status. Additionally, the processor circuitry can be further configured to perform a wireless measurement according to the prioritization between the intra-frequency measurement signal and the uplink transmission signal.

Abstract: Systems and methods for the use of measurement object having multiple synchronization signal block (SSB) -based measurement timing configurations (SMTCs) indicating a same periodicity and different offsets are disclosed herein. In some of these cases, a wireless communications network can provide a user equipment (UE) with a measurement object (MO) having up to a total number of total SMTCs, or having SMTC sets each of up to a predetermined number of SMTCs. UE determinations regarding a number of the SMTCs to use to perform one or more corresponding SSB measurements during a period of a periodicity indicated by one or more SMTCs of an MO are also discussed. The use of scheduling restrictions by the UE based on non-terrestrial network (NTN) characteristics of one or more of a serving cell and a neighbor cell to be measured are also discussed.

Abstract: A user equipment (UE), baseband processor or other network device (e.g., base station, next generation NodeB, etc. ) can operate to process or generate measurement gap configurations associated with multiple universal subscriber identity modules (MUSIM) with dual subscriber identify modules (SIMs). A UE can perform a system information request or an SI reading with or without the SI request based on a UE configured interruption or a preconfigured measurement gap configuration to read a system information block (SIB) 1 and at least one other SIB of SI associated with the target network.

Abstract: A user equipment (UE), baseband processor or other network device (e.g., base station, next generation NodeB, etc. ) can operate to configure a hand over (HO) or a primary secondary cell (PSCell) addition based on a channel state information reference signal (CSI-RS) based contention free random access (CFRA) procedure. A CSI-RS rough timing of a CSI-RS position can be determined based on a synchronization signal block (SSB) associated with a CSI-RS or a serving cell timing. A CFRA transmit timing can be determined based on the CSI-RS rough timing or a CSI-RS fine timing that is derived from a timing and frequency (T/F) tracking operation on the CSI-RS. Reference signal receive power (RSRP) measurement (s) can be made on the CSI-RS for performing the CSI-RS based CFRA procedure with transmissions according to the CSI-RS transmit timing of the CSI-RS that satisfies an RSRP threshold.

Abstract: Triggering an uplink (UL) gap at a base station may include decoding a user equipment (UE) UL gap capability report received from a UE. A radio resource control (RRC) UL gap configuration for transmission to the UE may be encoded. The RRC UL gap configuration may include configuration information associated with at least one of a periodicity, offset, or length. Measurement information received from the UE may be decoded. The measurement information may include at least one of a power headroom value, a PCMAX, f, c value, or a P value. Based on the power headroom value, the PCMAX, f, c value, or the P value, the UL gap configuration may be activated by encoding a medium access control (MAC) control element (MAC CE) for transmission to the UE.

Abstract: Activating an uplink (UL) gap at a base station may include decoding a user equipment (UE) UL gap capability report received from a UE. A radio resource control (RRC) UL gap configuration may be encoded for transmission to the UE. A power headroom report (PHR) medium access control (MAC) control element (CE) received from the UE may be decoded. The PHR MAC CE may include at least one of a P value or a power management maximum power reduction (P-MPR) value. Decoding the measurement information may include determining that the P value is equal to one or the P-MPR value is greater than zero. Based on determining that the P value is equal to one or the P-MPR value is greater than zero, the UL gap configuration may be implicitly activated.
