Publication number: 20230122107Abstract: A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.Type: ApplicationFiled: December 16, 2022Publication date: April 20, 2023Inventors: Wei Zhang, Frangli Xu, Haitong Sun, Sriram Subramanian, Vishwanth Kamala Govindaraju, Johnson O.

Patent number: 11387949Abstract: This disclosure relates to methods and devices for transmitting acknowledgment messages on a preferred cell in a carrier aggregation scenario. A user equipment device (UE) establishes a connection with a primary cell and one or more secondary cells, and determines a preferred cell from among the primary cell and the one or more secondary cells based at least in part on one or more quality metrics. The UE may determine the preferred cell at least in part in response to determining that transmission power of the UE has been limited due to a specific absorption rate (SAR) backoff feature of the UE. The UE transmits a notification to a network indicating that the UE intends to transmit an acknowledgement message to the preferred cell, and transmits the acknowledgment message to the preferred cell.Type: GrantFiled: June 16, 2020Date of Patent: July 12, 2022Assignee: Apple Inc.Inventors: Sriram Subramanian, Tarakkumar G.

Publication number: 20210297885Abstract: A user equipment (UE) may skip certain measurements when it is unlikely that the UE will use the measurements. The UE determines that the UE is configured with one of a measurement gap or gapless measurements, identifies that a predetermined condition has been satisfied and implements a mitigation technique in response to identifying that the predetermined condition has been satisfied, wherein the mitigation technique includes omitting performing one of a measurement during the measurement gap or a gapless measurement, wherein the measurement or the gapless measurement corresponds to a first radio access technology (RAT) that is different than a second RAT on which the UE is currently camped.Type: ApplicationFiled: March 19, 2021Publication date: September 23, 2021Inventors: Tarakkumar G.

Publication number: 20210211972Abstract: A user equipment (UE) supports communication over a first (lower) frequency range and a second (higher) frequency range. The UE determines an extent of preference of the second frequency range over the first frequency range, e.g., based on one or more of the following: sensor measurements; physical channel measurements; battery conditions; weather conditions; voice call activity; indoor/outdoor/in-car status; learned relationships between previous location-time conditions and performance on the second frequency range; etc. The UE device may control search activity and/or measurement activity on the second frequency range based on the preference extent, e.g., by controlling rates of repetition of search and/or measurement on the second frequency range, or by adding a measurement bias to a measurement reporting threshold, or by adding a delay to a measurement reporting time for a measurement, or by disabling search and measurement on the second frequency range.Type: ApplicationFiled: October 29, 2020Publication date: July 8, 2021Inventors: Wei Zhang, Alosious Pradeep Prabhakar, Pengkai Zhao, Vijay Venkataraman, Junsung Lim, Zhu Ji, Johnson O.
