Patent number: 12224902Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit assistance information to a base station to request an update or a modification to one or more communication parameters configured at the UE. Such communication parameters may include a quantity of uplink multiple-input multiple-output (MIMO) layers, a quantity of downlink MIMO layers, a minimum scheduling offset, a maximum quantity of component carriers, or a maximum aggregated bandwidth for a secondary cell group (SCG). In some implementations, the UE may transmit the assistance information requesting the update or modification to one or more of such communication parameters based on detecting that the UE satisfies one or more triggering conditions or thresholds.Type: GrantFiled: January 6, 2021Date of Patent: February 11, 2025Assignee: QUALCOMM IncorporatedInventors: Arvind Vardarajan Santhanam, Brian Clarke Banister, Kuo-Chun Lee, Aamod Khandekar, Enoch Shiao-Kuang Lu, Satashu Goel, Daniel Amerga, Karthik Venkatram, Subashini Krishnamurthy, Xuepan Guan, Mouaffac Ambriss, Peter Pui Lok Ang, James Francis Geekie, Sasikanth Reddy Adapala, Sundaresan Tambaram Kailasam

Patent number: 12207243Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to select a set of beams to generate energy in a first coverage region (e.g., an out-of-coverage (OOC) region) to reduce the effects of a distorted electric field. The UE may select the set of beams based on gain parameters associated with a set of antennas at the UE, where the gain parameters are determined for communications in a second coverage region (e.g., an in-coverage (INC) region). In some examples, the UE may use iterative techniques to select the beams. In some examples, the UE may select the set of beams based on calculations using a set of codebook beams associated with the second coverage region. In some examples, the UE may additionally select the set of beams for communications in the second coverage region.Type: GrantFiled: October 28, 2021Date of Patent: January 21, 2025Assignee: QUALCOMM IncorporatedInventors: Amodh Kant Saxena, Mihir Vijay Laghate, Raghu Narayan Challa, Brian Clarke Banister

Patent number: 12177794Abstract: This disclosure provides systems, methods, and apparatuses for sharing a maximum transmit power limit between a first radio access technology (RAT) and a second RAT. In one aspect, a wireless communication apparatus may reduce the maximum transmit power limit of a first uplink signal associated with the first RAT to obtain a first transmit power. The wireless communication apparatus may allocate a second transmit power remaining from the maximum transmit power limit to a second uplink signal associated with the second RAT. The wireless communication apparatus may reduce the maximum transmit power limit when the wireless communication apparatus is located at a cell edge, and a higher priority of the first RAT in relation to the second RAT may otherwise result in the second transmit power of the second uplink signal not satisfying a threshold.Type: GrantFiled: March 9, 2022Date of Patent: December 24, 2024Assignee: QUALCOMM IncorporatedInventors: Sanghoon Kim, Brian Clarke Banister, Hari Sankar, Tom Chin, Wei-Jei Song, Alexei Yurievitch Gorokhov

Publication number: 20240172295Abstract: Aspects are provided which allow a UE to apply CFO compensation to resolve mismatched RAPIDs caused by uplink Doppler shifts in HST deployments. The UE obtains one or more RARs each including a RAPID, where each of the RARs is responsive to a random access message including a preamble. The UE determines, in each of a threshold number of the one or more RARs, that the RAPID of a corresponding RAR is different than the preamble of a corresponding random access message. The UE then offsets a carrier frequency for each of one or more subsequent random access messages in response to the determination. As a result, mismatched RAPIDs due to uplink Doppler shifts may be avoided and RACH success rates may thereby be improved.Type: ApplicationFiled: May 29, 2021Publication date: May 23, 2024Inventors: Yuyu YAN, Liang HONG, Jie MAO, Levent AYDIN, Erman KOKEN, yongle WU, Rebecca Wen-Ling YUAN, Ziad AHMAD, Brian Clarke BANISTER, Ashok MANTRAVADI, Nanrun WU, Xinyu WANG, Jie ZHU
