Patent number: 11722275Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured to transmit sounding reference signals (SRSs) on a first carrier over multiple symbols within a slot, the first carrier being different from a second carrier on which the UE communicates with a base station during the slot. For example, the base station may transmit, to the UE, an SRS configuration for the UE to transmit the SRSs. In accordance with the control message, the UE may tune to the first carrier and may transmit the SRSs over the multiple symbols within the slot on the first carrier before tuning back to the second carrier. In some examples, the UE may transmit a capability message to the base station indicating that the UE supports transmitting SRSs over multiple symbols within a slot before tuning back to a different carrier.Type: GrantFiled: May 7, 2021Date of Patent: August 8, 2023Assignee: QUALCOMM IncorporatedInventors: Pranay Sudeep Rungta, Arvind Vardarajan Santhanam, Mona Agrawal

Patent number: 11153793Abstract: Wireless communication methods, devices, and systems to reduce latency when network access (e.g., cellular network access) is barred are described. A method includes receiving, by a user equipment (UE) from an application, a request for at least one of establishment of a packet data unit (PDU) session or uplink (UL) data transfer via a previously established PDU session. The method additionally includes evaluating that access to a first network (e.g., a 3rd Generation Partnership Project (3GPP) network) is barred. The method also includes determining that the access barring time exceeds a threshold, and checking, in response to the determining, that configured policies permit the PDU session to be on a second network (e.g., a non-3GPP network). The method further includes transferring data of the PDU session in accordance with the configured policies. Other aspects and features are also claimed and described.Type: GrantFiled: April 17, 2019Date of Patent: October 19, 2021Assignee: QUALCOMM IncorporatedInventors: Feilu Liu, Suli Zhao, Can Zhao, Mona Agrawal

Patent number: 10791463Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured to include procedures to mitigate denial of service (DoS) attack by a rogue base station when the initial non-access stratum (NAS) messages between the UE and a mobility management entity (MME) is unprotected. UE may maintain a temporary forbidden network list, which resides outside a subscriber identity module (SIM), and update a forbidden network list, which resides on the SIM, only under certain conditions. For example, a visited network, from which the UE receives a reject message, may be added to the forbidden network list on the SIM only when a counter associated with the visited network is equal to a maximum counter value, which is configured by the UE.Type: GrantFiled: November 11, 2019Date of Patent: September 29, 2020Assignee: QUALCOMM IncorporatedInventors: Swathi Seshadri, Cogol Tina, Abhishek Bhatnagar, Mona Agrawal
