Patent number: 11589320Abstract: Some techniques and apparatuses described herein permit a user equipment (UE) to transition among different power configurations, which include different values for different power parameters, that impact an amount of power consumed by the UE. In some aspects, these transitions may be signaled by a base station based at least in part on traffic volume for the UE, which may assist with improving throughput and/or extending battery life of the UE. Furthermore, these transitions may be signaled dynamically, such as in downlink control information (DCI) and/or a medium access control (MAC) control element (CE) MAC-CE, which may conserve battery power and/or network resources as compared to reconfiguring the UE using an RRC message, and which may allow the UE to be reconfigured quickly as conditions associated with the UE change.Type: GrantFiled: June 9, 2021Date of Patent: February 21, 2023Assignee: QUALCOMM IncorporatedInventors: Huilin Xu, Peter Pui Lok Ang, Wanshi Chen, Joseph Binamira Soriaga, Linhai He

Patent number: 11469740Abstract: Adaptive self-tunable antenna systems and methods are provided including a closed-loop system for sensing near-field RF signals of transmitted RF signals and tuning an antenna or switching between multiple antennas, so that the strength of the transmitted RF signals is maximized. A sensing antenna detects the near-field RF signal, which is filtered and converted to an RF strength control signal that can be used to generate an antenna tuning control signal. An antenna tuner uses the antenna tuning control signal to keep the antenna in resonance by dynamically changing the electrical length of the antenna or switching between multiple antennas to maximize the strength of the radiated RF signal. Such antennas may be less prone to detuning due to interaction with human bodies or other objects. Dynamically matching the antennas to an RF power amplifier and low noise amplifier can improve stability, power efficiency, gain, noise figure, and receiver sensitivity.Type: GrantFiled: July 8, 2019Date of Patent: October 11, 2022Assignee: Shure Acquisition Holdings, Inc.Inventor: Christopher Zachara
