Based on the SIRE, the UE is configured to select a Transmission Power Control (TPC) command sequence for a low power mode of operation of the UE in which a receiver is powered down. The UE is further configured to activate the low power mode and transmit the selected TPC command sequence to the base station to adjust a DL transmission power during the low power mode.Type: GrantFiled: September 16, 2013Date of Patent: November 10, 2015Assignee: QUALCOMM IncorporatedInventors: Harish Venkatachari, Nate Chizgi, Prashant Udupa Sripathi, Atul Arvind Salvekar, Sharif Ahsanul Matin
