Patent number: 11770228Abstract: Apparatus and methods for sounding reference signal (SRS) switching are provided. In certain embodiments, transmit path resources of user equipment (UE) are used to reduce or eliminate the impairment of SRS upon transport capacity. Furthermore, the transmit path resources can be used for other purposes, and thus SRS switching time can be reduced by re-using transmit path resources that may be included for other purposes. The teachings herein can be used to achieve SRS switching of 0 ?s, thereby eliminating the impact of switching timing constraints for SRS symbols on transport capacity.Type: GrantFiled: January 23, 2023Date of Patent: September 26, 2023Assignee: Skyworks Solutions, Inc.Inventors: Dominique Michel Yves Brunel, Laurent Noel

Patent number: 9461853Abstract: An automatic gain control (AGC) method and system for a radio receiver are proposed in which the ACG comprises two AGC loops; a first loop controlling signal gain in the analogue portion of the radio receiver, a second loop controlling gain in the digital domain after digitization of the received signal. The analogue AGC loop has a slower response time than the digital AGC loop. When applied to a multi-branch diversity receiver, each branch has its own digital AGC loop, but the analogue gain can be common to all branches, based on measurement of the analogue signal in each branch.Type: GrantFiled: December 8, 2014Date of Patent: October 4, 2016Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (publ)Inventors: Jean-Marc Aznar, Stefania Sesia, Laurent Noel
