Patent number: 11871361Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that uplink communications are to be performed between the UE and a first cell group associated with a first radio access technology (RAT) and between the UE and a second cell group associated with a second RAT. The UE may determine that the UE is configured for power sharing for the uplink communications with the first cell group associated with the first RAT and the second cell group associated with the second RAT.

Publication number: 20230319735Abstract: Aspects described herein relate to energy headroom report (EHR) and sustainable duty cycle (SDC) reporting for dynamic power aggregation. In one example, a user equipment (UE) may identify an available energy or available time period for an uplink transmission via uplink carrier aggregation or dual connectivity. The UE may further transmit, to a network entity, a report including the available energy or available time period for uplink transmission. In another example, a network entity may transmit a configuration message to configure the UE with carrier aggregation or dual connectivity. The network entity may further receive a report including the available energy or time for uplink transmission via carrier aggregation or dual connectivity. The network entity may further adjust uplink communication with the UE based on the received report.Type: ApplicationFiled: April 1, 2022Publication date: October 5, 2023Inventors: Kazuki TAKEDA, Gokul SRIDHARAN, Timo Ville VINTOLA, Gene FONG

Publication number: 20220369245Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use dynamic power aggregation techniques to perform instantaneous transmit power adjustments in an uplink carrier aggregation configuration. For example, the UE may dynamically adjust the instantaneous transmit power with network assistance. In some cases, the base station may configure a set of power aggregation parameters to control the instantaneous transmit power behavior of the UE. The UE may adjust the instantaneous transmit power in accordance with the power aggregation parameters. In some other cases, the base station may configure the UE to report one or more parameters. Based on the report, the base station may determine a power aggregation configuration for the UE in a time interval. In some other cases, the UE may be configured to scale the instantaneous transmit power for individual component carriers in the carrier aggregation configuration.Type: ApplicationFiled: May 17, 2021Publication date: November 17, 2022Inventors: Kazuki Takeda, Peter Gaal, Juan Montojo, Alberto Rico Alvarino, Gokul Sridharan, Gene Fong, Wanshi Chen, Tao Luo

Patent number: 10904781Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may mitigate self-interference and intermodulation products caused by communicating over two carriers in order to improve measurements of a third carrier. The UE may determine a measurement configuration to determine the quality of the third carrier. The measurement configuration may include identifying time periods with no scheduled uplink transmissions, time periods with a transmit power below a power threshold, time periods with frequency locations with an expected lower intermodulation interference, or time periods with a scheduled reference signal transmission (e.g., a synchronization signal (SS) block). The UE may also reduce a transmit power for a time period or drop a scheduled uplink transmission in order to perform more accurate measurements on the third carrier. In some cases, a base station may schedule a measurement gap for the UE to perform the measurements.Type: GrantFiled: September 7, 2018Date of Patent: January 26, 2021Assignee: QUALCOMM IncorporatedInventors: Valentin Alexandru Gheorghiu, Gene Fong, Sumit Verma

Patent number: 10582459Abstract: A method, computer-readable medium, and apparatus operate to reduce or eliminate interference with one or more other communication systems having specific transmission requirements within a specific geographic area. For example, aspects operate by determining that a user equipment (UE) is in a protection zone where additional transmission requirements apply. The additional transmission requirements enable coexistence with one or more other communication systems in the protection zone. The UE may identify, based on being in the protection zone and a coexistence mode, one or more transmit emission limit requirements to be met. The UE may identify, based on being in the protection zone and the coexistence mode, one or more maximum transmit power requirements to be met. The UE may configure a transmit output power, at which the UE can meet the one or more transmit emission limit requirements and the one or more maximum transmit power requirements.Type: GrantFiled: April 30, 2019Date of Patent: March 3, 2020Assignee: QUALCOMM IncorporatedInventors: Kapil Gulati, Tien Viet Nguyen, Gene Fong, Shailesh Patil, Sudhir Kumar Baghel

Patent number: 10517050Abstract: Additional requirements for spectrum emissions may be matched with regional requirements, and an additional maximum power reduction (A-MPR) for a user equipment (UE) may be based on an actual antenna gain of the UE. For example, a UE may be located in a particular region and be required to meet regional requirements for wireless communications. In such cases, the UE may receive network signaling from a base station, and identify an antenna gain for its antenna. The UE may then identify a set of emission requirements based on the identified antenna gain and the network signaling. Additionally, the UE may identify an A-MPR based on the set of emission requirements and the antenna gain and may adjust a maximum output power in accordance with the identified A-MPR. In some examples, an output power threshold may be derived using a difference between a regional requirement and the UE's antenna gain.Type: GrantFiled: September 17, 2018Date of Patent: December 24, 2019Assignee: QUALCOMM IncorporatedInventors: Tien Viet Nguyen, Shailesh Patil, Kapil Gulati, Sudhir Kumar Baghel, Gene Fong, John Forrester

Patent number: 9775078Abstract: Techniques for mitigating data loss during autonomous system information (SI) reading by a user equipment (UE) are described. For autonomous SI reading, the UE may autonomously determine when to read system information from neighbor cells and may not inform a serving cell. In one design, the UE may autonomously select a SI reading gap for reading system information from a neighbor cell. During the SI reading gap, the UE may suspend reception of downlink transmission from the serving cell, receive system information from the neighbor cell, and maintain capability to transmit on the uplink to the serving cell. In one design, the serving cell may determine SI reading gaps autonomously selected by the UE for reading system information from neighbor cells. The serving cell may communicate with the UE by accounting for the SI reading gaps of the UE, e.g., may suspend communication with the UE during the SI reading gaps.Type: GrantFiled: October 19, 2015Date of Patent: September 26, 2017Assignee: QUALCOMM IncorporatedInventors: Tingfang Ji, Peter Gaal, Gene Fong, Kapil Bhattad, Yongbin Wei
