Patent number: 10575233Abstract: Methods and apparatuses for wireless communication are provided. In some aspects, a user equipment (UE) may obtain a gain value based on a difference between an reference signal receive power (RSRP) value of a first antenna and an RSRP value of a second antenna, where the first antenna may be located on an exterior of the UE and the second antenna may be located within an interior of the UE. Further, in some aspects, the UE may obtain an antenna gain value based at least on a random access channel (RACH) power value and a reference signal receive quality (RSRQ) offset value. Additionally, in some aspects, the UE may obtain the antenna gain value based on one of a matching entry in a memory log or a minimum of a maximum antenna gain value or an aggregation of a RACH gain value and an RSRQ offset value.Type: GrantFiled: November 10, 2017Date of Patent: February 25, 2020Assignee: QUALCOMM IncorporatedInventors: Madhusudan Kinthada Venkata, Srinivasan Balasubramanian, Raj Surya Pratha, Manjinder Singh Sandhu, Siva Kumar Jujaray

Patent number: 10045244Abstract: A multi-antenna device configured for addressing connection performance issues in UL/DL imbalance scenarios is described. The device may identify a potential UL/DL imbalance scenario and select signal measurements associated with either a primary antenna or a diversity antenna for mobility procedures and/or mobility measurement reporting based on the detected imbalance. In one example, the device may receive a signal at both the primary and a diversity antenna and may identify an imbalance between the primary and diversity signal measurements. The device may then compare the identified imbalance with an imbalance threshold and may select the primary or diversity signal measurement for mobility procedures and/or measurement reporting based at least in part on the comparison. For instance, if the imbalance is greater than the imbalance threshold the device may use the primary signal measurements and may otherwise use the stronger of the primary or diversity signal measurements.Type: GrantFiled: August 4, 2016Date of Patent: August 7, 2018Assignee: Qualcomm IncorporatedInventors: Nikhil Mali, Madhusudan Kinthada Venkata, Siva Kumar Jujaray, Manjinder Singh Sandhu

Patent number: 9967766Abstract: Certain aspects of the present disclosure relate to methods and apparatus for adaptive antenna switching for measurements, for example, in high gain automotive devices. According to certain aspects, a method is provided herein for wireless communications. The method generally includes selecting, based on one or more conditions, a first measurement configuration that uses at least an external antenna mounted on a surface of a vehicle for one or more measurements or a second measurement configuration that uses at least an internal antenna associated with the vehicle for the one or more measurements; performing the one or more measurements using the selected measurement configuration; and sending a report based on the one or more measurements. The techniques for measurement configuration selection may allow the device to achieve the benefits of both the high gain external antenna and the lower gain internal antenna(s) depending on the current conditions.Type: GrantFiled: February 29, 2016Date of Patent: May 8, 2018Assignee: QUALCOMM IncorporatedInventors: Madhusudan Kinthada Venkata, Srinivasan Balasubramanian, Manjinder Singh Sandhu, Abhinav Dayal, Siva Kumar Jujaray, Raj Surya Pratha

Patent number: 9923610Abstract: An apparatus for selective usage of antennas for measurement purposes is provided. When the signal strength of the primary antenna is less than a signal strength threshold or the signal quality of the primary antenna is less than a signal quality threshold, the apparatus may determine at least one of whether a first difference between the signal strength of the primary antenna and the diversity antenna satisfies a first criteria or whether a second difference between the signal quality of the primary antenna and the diversity antenna satisfies a second criteria. When at least one of the first difference satisfies the first criteria or the second difference satisfies the second criteria, the apparatus may calculate the signal strength and signal quality of the diversity antenna for measurement evaluations and path-loss calculation based on the signal strength and signal quality of the primary antenna.Type: GrantFiled: September 13, 2016Date of Patent: March 20, 2018Assignee: QUALCOMM IncorporatedInventors: Manjinder Singh Sandhu, Madhusudan Kinthada Venkata, Siva Kumar Jujaray

Publication number: 20160119896Abstract: Certain aspects of the present methods for handling user equipment (UE) pages in a Radio Resource Control (RRC) connected mode of the UE. Aspects of the present disclosure may effectively scale a point (in time) until which the UE shall handle pages in the RRC connected mode, and after which the UE detects out-of-sync with the NW, which may allow the UE to performs procedures that may help enhance user experience.Type: ApplicationFiled: October 21, 2015Publication date: April 28, 2016Inventors: Siva Kumar JUJARAY, Madhusudan KINTHADA VENKATA, Arun Prasanth BALASUBRAMANIAN, Daniel AMERGA, Nitin PANT, Shyamal RAMACHANDRAN, Pankaj Subhash VASANDANI, Arvind Vardarajan SANTHANAM

Publication number: 20150341938Abstract: A user equipment (UE) may have data in a buffer for uplink (UL) transmission. The UE may transmit a buffer status report (BSR) indicating the amount of data. The BSR may fail or a base station may not grant sufficient resources for transmission of the data. A BSR failure condition may be based on a radio link control (RLC) operating mode of the data. For example, the data may be an acknowledgement (ACK) for an acknowledged mode (AM) DL transmission. In this case, the UE may initiate a BSR retransmission (Retx-BSR) timer and determine whether any duplicate transmissions have been received. The data may also be associated with an unacknowledged mode (UM), and the BSR failure condition may include waiting for a time interval that is less than the Retx-BSR time interval. When the BSR failure condition is satisfied, the UE may transmit a scheduling request to the base station.Type: ApplicationFiled: May 22, 2014Publication date: November 26, 2015Applicant: QUALCOMM IncorporatedInventors: Mohammed Tawashi, Siva Kumar Jujaray, Mouaffac Ambriss, Amir Aminzadeh Gohari, Masato Kitazoe, Aziz Gholmieh, Gang Andy Xiao, Madhusudan Kinthada Venkata, Srinivasan Balasubramanian
