Patent number: 11258572Abstract: Systems, apparatuses, and methods for computing transport block size (TBS) for channels with shortened transmission time interval (sTTI). An initial size may be determined based on one or more TBS tables. The initial size may be scaled by a factor associated with an sTTI channel. A TBS table is selected based on the one or more TBS tables. The scaled size may be rounded based on the selected TBS table to generate a TBS for the sTTI channel.Type: GrantFiled: February 7, 2019Date of Patent: February 22, 2022Assignee: QUALCOMM IncorporatedInventors: Seyedkianoush Hosseini, Amir Farajidana, Ahmed Omar Desouky Ali, Thiagarajan Sivanadyan, Wenshu Zhang, Pengkai Zhao

Patent number: 9986479Abstract: Aspects of the present disclosure relate to performing a tune-away from a first radio access technology (RAT) to a second RAT. These techniques include, for example, a method in which one or more radio resources of a user equipment are tuned away from the first RAT (e.g., LTE technology) to the second RAT (e.g., legacy 2G/3G technology and/or Wi-Fi or Bluetooth technology). Based on detecting a need to tune away one or more radio resources, the UE may then determine a tune-away metric for each serving cell based on one or more performance impact factors associated with the serving cell being tuned away. The UE may select one or more of the cells to be tuned away based on the determined tune-away metrics. The UE may then tune one or more radio resources corresponding to the selected at least one cell away from the first RAT to the second RAT.Type: GrantFiled: March 1, 2016Date of Patent: May 29, 2018Assignee: QUALCOMM IncorporatedInventors: Leena Zacharias, Aziz Gholmieh, Thiagarajan Sivanadyan, Amit Mahajan

Publication number: 20160112907Abstract: User equipment (UE) based pseudo-reselection occurs from a first wireless cell to a second wireless cell. A UE autonomously discovers candidate reselection frequencies and autonomously sets reselection thresholds. The UE perform cell reselection based on the discovered candidate cell reselection frequencies and the autonomously set thresholds.Type: ApplicationFiled: February 6, 2015Publication date: April 21, 2016Inventors: Thawatt GOPAL, Reza SHAHIDI, Mungal Singh DHANDA, Thiagarajan SIVANADYAN, Bhanu Kiran JANGA, Zhang ZHOU, Tom CHIN

Patent number: 9083415Abstract: Methods, devices, and computer program products for antenna searching with antenna selection are disclosed. In one aspect, an apparatus operable in a wireless communication system includes a first receiver, a second receiver, and a processor. The first receiver receives a first signal including pilot signals from a first antenna. The second receiver receives a second signal including pilot signals from a second antenna. The processor, while a receive diversity is enabled, demodulates the first and second signals, determines whether a first condition is satisfied, and, in response to determining that the first condition is satisfied, searches for pilot signals via the second receiver and not the first receiver. The first condition is satisfied when a signal strength of the first signal does not exceed a first threshold and a signal strength of the second signal exceeds a second threshold.Type: GrantFiled: October 23, 2012Date of Patent: July 14, 2015Assignee: QUALCOMM IncorporatedInventors: Francis Ming-Meng Ngai, Stanley Tsai, Thiagarajan Sivanadyan
