Patent number: 12342213Abstract: Apparatuses, systems, and methods for UL traffic throughput enhancements in NSA deployments. A UE may determine that an UL data requirement is substantially greater than a DL data requirement. The UE may perform an UL enhancement procedure based on UL enhancement conditions. The UL enhancement conditions may include determining that a master cell group does or does not operate according to LTE, determining that UL data traffic is only carried via LTE bands or that UL data traffic is split between LTE bands and NR bands, determining that UL carrier aggregation is or is not available, and/or determining that blind secondary cell group addition is supported or is not support by a network. The UE may be configured to perform the at least one UL enhancement procedure thereby enhancing uplink throughput.Type: GrantFiled: May 28, 2021Date of Patent: June 24, 2025Assignee: Apple Inc.Inventors: Rodney G.

Publication number: 20250080306Abstract: Techniques described herein includes solutions for mitigating interference related to antenna switching. A user equipment (UE) may determine a potential for interference to data reception on a second frequency band due to antenna switching associated with transmission of reference signals on a first frequency band. In response to the determination, the UE may select one or more interference mitigation measures based on an operating mode of the UE and one or more UE parameters. An interference mitigation measure may include backing off on a reported value, such as a channel quality indicator (CQI), rank indicator (RI), or reference signal received power (RSRP). The interference mitigation measure may further include skipping reference signal transmission on the first frequency band and the antenna switching associated therewith.Type: ApplicationFiled: September 1, 2023Publication date: March 6, 2025Inventors: Vijay Venkataraman, Pranav Tripathi, Han Pu, Bin Feng, Dhiraj J.

Publication number: 20250031139Abstract: Systems, devices and methods for a user equipment (UE) to perform public land mobile network (PLMN) selection with a non-terrestrial network (NTN). A UE performs a non-access stratum (NAS) procedure with a public land mobile network (PLMN) of an NTN. The UE receives a NAS message from the PLMN, and the NAS message indicates that the UE is not allowed to access a core network of the NTN. The NAS message may indicate that the UE is not allowed to access the core network of the NTN because a location of the UE is unknown to the NTN, that access to the NTN is not allowed in a country in which the UE is located, or that a location of the UE is not within a country associated with the NTN. The UE modifies its PLMN search procedure responsive to receiving the NAS message.Type: ApplicationFiled: October 4, 2024Publication date: January 23, 2025Inventors: Rohit R.

Patent number: 12010614Abstract: Systems, devices and methods for a user equipment (UE) to perform public land mobile network (PLMN) selection with a non-terrestrial network (NTN) dedicated to an international area. The UE receives a downlink message from the NTN, where the downlink message includes a public land mobile network (PLMN) identifier of a first PLMN of the NTN including an information element (IE). The IE indicates that the NTN is dedicated to an international area. Responsive to receiving the downlink message, the UE determines a current location of the UE and determines whether the current location is in the international area. The UE provides an international area notification to an access and mobility management function (AMF) servicing the UE to forward to a home PLMN (HPLMN) of the UE indicating whether the current location is in the international area.Type: GrantFiled: January 14, 2022Date of Patent: June 11, 2024Assignee: Apple Inc.Inventors: Mohammed Sadique, Alosious Pradeep Prabhakar, Chunlei Lin, Han Pu, Krisztian Kiss, Rohit R.

Publication number: 20230319611Abstract: Techniques and wireless devices to perform adaptive measurement object prioritization in a cellular communication scenario. A wireless link is established by the wireless device with a serving cell of a cellular base station. Adaptive measurement object prioritization is implemented responsive to determining that a trigger condition has occurred. A configuration message is received from the base station, where the configuration indicates a plurality of measurement objects including both Long Term Evolution (LTE) and New Radio (NR) measurement objects. A first measurement object of the plurality of measurement objects is selected to prioritize for measurement. The first measurement object is measured during a first measurement gap prior to measuring one or more second measurement objects of the plurality of measurement objects, and a measurement report is provided to the serving cell specifying a measurement result of the first measurement object.Type: ApplicationFiled: March 24, 2023Publication date: October 5, 2023Inventors: ChunLei Lin, Bin Feng, Vijay Venkataraman, Alosious Pradeep Prabhakar
