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.

Abstract: Techniques are directed toward measuring a synchronization signal block (SSB) outside an active bandwidth part (BWP). An example method includes a user equipment (UE) transmitting an indication of a capability to measure a synchronization signal block (SSB) outside of an active bandwidth part (BWP) to a base station. The method can further include the UE receiving, based on the transmission, a first configuration parameter for identifying a first BWP and a second BWP, a second configuration parameter for identifying the first BWP as an active BWP, and a third configuration parameter for identifying a frequency that is carrying the SSB. The method can further include the UE detecting the SSB in the second BWP and outside of the active BWP. The method can further include the UE measuring the SSB.

Abstract: Embodiments of the present disclosure enable a user equipment (UE) to performing inter-Radio Access Technology (RAT) measurements. The UE determines whether one or more inter-RAT measurement object (MO) is configured with or without a measurement gap (MG). When the one or more inter-RAT MO is on an NR serving component carrier (CC) with the MG, the UE performs an inter-RAT measurement on the NR serving CC based on whether the MG is fully overlapped or partially overlapped with synchronization signal blocks (SSBs) of a target MO of the one or more inter-RAT MO. When the one or more inter-RAT MO is on the NR serving CC without the MG, the UE performs the inter-RAT measurement on the NR serving CC based on whether a target SSB of the target MO is within or outside an active bandwidth part (BWP) of the NR serving CC.

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: The present application relates to devices and components including apparatus, systems, and methods for triggering and using uplink gaps in cellular networks. A method of an embodiment comprises: transmitting, to a base station, an indication of an uplink (UL) gap capability or preference of the UE for body proximity sensing (BPS) or transceiver calibration; activating a UL gap configuration based on an activation command received from a network; and performing operations for BPS or transceiver calibration within a UL gap defined by the UL gap configuration.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform measurements on reference signals based on concurrent measurement gaps. In an example, a device supports concurrent measurement gaps for intra-RAT measurements. The device can also indicate to a network whether it supports concurrent measurement gaps for inter-RAT measurements. Based on this indication, the network can configure measurement gap patterns and measurement objects for the UE to perform intra-RAT measurements and, as applicable, inter-RAT measurements.

Abstract: Aspects are presented herein of apparatuses, systems, and methods for measurement gap configuration. A cellular network may establish communication with a UE using a first and second cell. The cellular network may configure bandwidth parts (BWPs) for the first and second cell, including a first and second BWP for the first cell and a third and fourth BWP for the second cell. A measurement gap configuration that specifies when the UE is to use a first measurement gap pattern may be provided to the UE. At a first time, the cellular network may communicate with the UE using the first BWP for the first cell and the third BWP for the second cell, based on the first measurement gap pattern. At a second time, the cellular network may communicate with the UE using the second BWP for the first cell based on a modification of the first measurement gap pattern.
