Abstract: A first transmission power level based on a radio frequency exposure limit and a second transmission power level based on the first transmission power level and a probability of detection of a body by a body proximity sensor are determined, where it is ensured that an average usage of the first and second transmission power levels over time does not exceed the transmission power limit, determined based on radio frequency exposure limits. A transmission power gain is determined based on a difference between the first and second transmission power level based on the probability of detection, and a false alarm rate of the body by the body proximity sensor. The transmission power gain may be used as a performance indicator to select from multiple first and second transmission power gains. First and second transmission power gains corresponding to the selected transmission power gain may be stored and applied during transmission.

Abstract: Apparatuses for FR2 UL gap configuration, and associated configuring methods. In one aspect, a dedicated radio resource control (RRC) signaling is used to configure a UL gap by transmitting. The UL gap configuration may indicate a reference cell to determine a UL gap pattern for a multi-radio dual connectivity (MR-DC) configuration. The UL gap configuration may indicate a system frame number (SFN) and a subframe of the reference cell used for calculating the UL gap pattern. The reference cell can be selected from a list of cells including FR1 cells or can be limited to FR2 cells.

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: Embodiments of the present disclosure relate to uplink (UL) gap triggering. According to embodiments of the present disclosure, a processor of user equipment is configured to perform following operations. The operations comprise transmitting to a network a user preference via a first signaling, wherein the user preference indicates a preference of the UE in uplink (UL) gap configuration; transmitting to the network an UL gap activation request via a second signaling, wherein the UL gap activation request indicates the network that an UL gap activation for the UE is needed; and transmitting to the network device an UL gap deactivation request via a third signaling, wherein the UL gap deactivation request indicates the network that an UL gap deactivation for the UE is needed..

Abstract: Techniques discussed herein can facilitate enhancements to measurement for a User Equipment (UE) in Radio Resource Control (RRC) Connected mode for configuration of Carrier Aggregation (CA) and/or Dual Connectivity (DC). One example embodiment comprises a UE device comprising a processor configured to perform operations comprising: transmitting a UE Assistance Information message comprising a measurement request; receiving a first RRCReconfiguration message comprising a measConfig information element (IE); performing one or more measurements on each of on one or more frequencies based at least on the RRC measConfig IE, wherein the one or more frequencies comprise at least one non-serving frequency associated with a neighboring cell; transmitting a MeasurementReport message that indicates the one or more measurements for at least one of the one or more frequencies; and receiving a second RRCReconfiguration message that configures the UE with the at least one of the one or more frequencies.

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.
