Patent number: 11974235Abstract: 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.Type: GrantFiled: July 27, 2021Date of Patent: April 30, 2024Assignee: APPLE INC.Inventors: Huaning Niu, Dawei Zhang, Jie Cui, Laxminarayana Pillutla, Manasa Raghavan, Qiming Li, Sharad Sambhwani, Xiang Chen, Yang Tang

Publication number: 20240032131Abstract: 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.Type: ApplicationFiled: July 27, 2021Publication date: January 25, 2024Inventors: Huaning Niu, Dawei Zhang, Jie Cui, Laxminarayana Pillutla, Manasa Raghavan, Qiming Li, Sharad Sambhwani, Xiang Chen, Yang Tang

Publication number: 20230413194Abstract: An electronic device may include a radio that generates a first maximum power based on a radio-frequency exposure (RFE) budget. The radio may transmit signals subject to the first maximum power during a subperiod of an averaging period and may generate an instantaneous RFE metric value based on an antenna coefficient and the conducted transmit power of the antenna during the subperiod. The radio may generate a consumed RFE value by averaging the instantaneous RFE metric value with previous instantaneous RFE values from the averaging period, may generate a remaining budget based on the consumed RFE value, may generate a second maximum transmit power based on the remaining budget, and may transmit signals during a subsequent subperiod subject to the second maximum power. Time-averaging the RFE metric may serve to optimize performance of the radio relative to scenarios where the radio performs time-averaging of conducted TX power.Type: ApplicationFiled: August 31, 2023Publication date: December 21, 2023Inventors: Sharad Sambhwani, Digvijay A.

Publication number: 20230132977Abstract: 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.Type: ApplicationFiled: May 18, 2022Publication date: May 4, 2023Inventors: Sharad Sambhwani, Huaning Niu, Xiang Chen, Yang Tang, Laxminarayana Pillutla, Dirk Nickisch

Publication number: 20230083550Abstract: An electronic device may include a set of antenna panels (APs) that transmit and receive signals within a set of signal beams. A proximity sensor such as a radar sensor may gather sensor data indicative of the position an external object. The device may select an AP and a beam that maximize wireless performance in communicating with a base station while also complying with the radio-frequency exposure (RFE). The device may select the AP and the beam based on the sensor data, per-panel and per-beam projected RFE values, antenna port RFE characteristics, per-panel and per-beam transmit power limits, per-beam transmit power backoffs, an RFE lookup table, regulatory RFE limits, and antenna performance metrics. The device may transmit an RFE report to the base station that identifies some or all of this information for use in updating scheduling for the device.Type: ApplicationFiled: September 6, 2022Publication date: March 16, 2023Inventors: Sharad Sambhwani, Dirk Nickisch, Laxminarayana Pillutla, Mark G Forbes

Publication number: 20220368366Abstract: An electronic device may include a first set of radios subject to a specific absorption rate (SAR) limit and a second set of radios subject to a maximum permissible exposure (MPE) limit over an averaging period. Control circuitry may dynamically adjust radio-frequency (RF) exposure metric budgets provided to the radios over the averaging period, based on feedback reports from the radios identifying the amount of SAR and MPE consumed by the radios during different subperiods of the averaging period. The control circuitry may distribute and adjust SAR budgets and MPE budgets across the radios based on the feedback reports, distribution policies, radio statuses, transmit activity factors, and/or usage ratios associated with the radios. This may provide efficient utilization of the total available SAR and MPE budget, thereby leading to increased uplink coverage and throughput relative to scenarios where the SAR and MPE budgets remain static.Type: ApplicationFiled: July 19, 2022Publication date: November 17, 2022Inventors: Sharad Sambhwani, Digvijay A.
