Patent number: 9936453Abstract: Methods, systems, and devices for wireless communication are described. The described techniques allow a user equipment (UE) to conserve power after transitioning from one coverage mode to another coverage mode based on power consumption estimates. The UE may make a determination on whether to modify its current extended discontinuous reception (eDRX) values by either triggering an unscheduled timing update or waiting for a scheduled timing update. For instance, the UE may estimate power consumption based on current eDRX values and the time remaining until a scheduled timing update procedure and compare this estimate to power consumption estimate based on modified eDRX values and the amount of power consumed to perform an unscheduled timing update procedure. Based on the comparison, the UE may update its eDRX values through an unscheduled TAU or through the regularly scheduled TAU procedure.Type: GrantFiled: July 24, 2017Date of Patent: April 3, 2018Assignee: QUALCOMM IncorporatedInventors: Ashish Shankar Iyer, Naveen Kumar Pasunooru, Prashanth Mohan, Raevanth Venkat Annam, Srihari Vodnala, Dhananjaya Sarma Ponukumati

Patent number: 9913247Abstract: Disclosed are techniques for notifying a user of a wireless mobile device of the contents of a signboard. In an aspect, the wireless mobile device receives a notification in a broadcast message transmitted on a broadcast channel of a short-range wireless network, the notification representing the contents of the signboard, decodes the notification without connecting to the short-range wireless network, and provides data representing the notification to the user of the wireless mobile device. In an aspect, a wireless access point coupled to the signboard encodes the notification in the broadcast message transmitted on the broadcast channel of the short-range wireless network supported by the wireless access point and broadcasts the notification in the broadcast message transmitted on the broadcast channel of the short-range wireless network.Type: GrantFiled: March 16, 2017Date of Patent: March 6, 2018Assignee: QUALCOMM IncorporatedInventors: Uday Kumar Chidurala, Dhananjaya Sarma Ponukumati, Sumanth Kumar Kota

Publication number: 20160174187Abstract: Methods and devices for improving data throughput and page performance of a multi-subscription wireless communication device with a shared radio frequency (RF) resource may include detecting when a random access channel (RACH) procedure required on a modem stack associated with the first SIM in order to access a first network will coincide with a scheduled tune-away period for the shared RF resource corresponding to a reservation for activity on a second network supported by the second SIM. When such coincidence is detected, the wireless communication device may periodically transmit preambles to the first network with increasing transmission power until an acknowledgment is received or the scheduled tune-away period starts. When the scheduled tune-away period starts, the wireless communication device may pause transmission of preambles and record virtual preambles. When the tune-away period ends, the wireless communication device may continue the RACH procedure based on actual and virtual preambles.Type: ApplicationFiled: December 15, 2014Publication date: June 16, 2016Inventors: Rajesh Gopala Krishnan, Dhananjaya Sarma Ponukumati

Patent number: 9282536Abstract: Access terminals employing multiple subscriptions are adapted for paging channel arbitration. According to at least one example, an access terminal can determine whether there will be a collision between a first paging channel associated with a first subscription and a second paging channel associated with a second subscription. The access terminal may additionally determine whether a time period between a paging indicator bit for the first subscription and the second paging channel is greater than or equal to an amount of time it takes to switch from operating on the first subscription to operating on the second subscription. The access terminal can monitor for a paging indicator bit indicating an incoming paging message on the first paging channel and, if no paging message is indicated, may switch to the second subscription to monitor the second paging channel for incoming paging messages. Other aspects, embodiments, and features are also included.Type: GrantFiled: August 13, 2013Date of Patent: March 8, 2016Assignee: QUALCOMM IncorporatedInventor: Dhananjaya Sarma Ponukumati
