Publication number: 20240146377Abstract: This disclosure provides systems, methods and apparatuses for enabling downlink throttling, such as for thermal mitigation. For example, a user equipment (UE) may transmit channel state feedback (CSF) with a report of a first rank that is less than a second rank associated with a channel condition and may communicate with a base station using a configuration associated with the first rank and without a set of sounding reference signals (SRSs). Alternatively, the UE may transmit one or more SRSs using a configuration associated with the first rank. In this way, by refraining from transmission of the SRSs or by adjusting the configuration the SRSs, the UE causes the base station to support downlink throttling.Type: ApplicationFiled: December 1, 2021Publication date: May 2, 2024Inventors: James Francis GEEKIE, Alexei Yurievitch GOROKHOV, Chun-Hao HSU, Mahbod GHELICHI, Sivaram Srivenkata PALAKODETY, Pranay Sudeep RUNGTA, Krishna Chaitanya MUKKERA, Adarsh Kumar JINNU

Patent number: 10278232Abstract: Aspects of the present disclosure provide an apparatus and methods for operating the same that can improve out-of-sync and radio link failure handling in a W-CDMA network. A user equipment (UE) establishes a packet switched (PS) connection between the UE and a base station, wherein the PS connection includes a Fractional Dedicated Physical Channel (F-DPCH).
