Patent number: 11026139Abstract: Methods, systems, and devices are described for concurrently performing handoff-related measurements for neighbor cells using multiple input multiple output (MIMO) antenna resources. In one example, a mobile device is in communication with a serving cell. Handoff-related measurements of first wireless signals from a first neighbor cell are performed. The first wireless signals are received at first MIMO antenna resources of a device. Handoff-related measurements of second wireless signals from a second neighbor cell are performed, as well. The second wireless signals are received at second MIMO antenna resources concurrently with the first wireless signals received at the first MIMO antenna resources. The first handoff-related measurements and the second handoff-related measurements may be performed during a scan interval. A type of handoff-related measurement to perform may be determined based on a determined length of the scan interval.Type: GrantFiled: November 22, 2019Date of Patent: June 1, 2021Assignee: QUALCOMM IncorporatedInventors: Steven D. Cheng, Remi J. Gurski, Kuo-Chun Lee, Tom Chin, Guangming Shi

Patent number: 8989061Abstract: A plurality of predetermined amplifier gain states for a low noise amplifier (LNA) are run during initial acquisition in a time division duplex (TDD) system. Acquisition of a received signal is determined based on searching across the plurality of predetermined amplifier gain states. Forcing the amplifier gain into a set of predetermined gain states affords quicker resolution of initial acquisition for setting the gain of the LNA, which in TDD systems is complicated due to an uncertain uplink/downlink timeline that precludes continuous operation of a gain setting algorithm run in the LNA.Type: GrantFiled: June 8, 2010Date of Patent: March 24, 2015Assignee: QUALCOMM IncorporatedInventors: Remi J. Gurski, Matthias Brehler, Raghu N. Challa

Patent number: 8416733Abstract: Techniques for performing time tracking in a communication system utilizing a cyclic prefix are described. In an aspect, a receiver may detect for large timing errors based on early and late received samples obtained with early and late FFT windows, respectively. The receiver may derive first and second channel impulse response (CIR) estimates based on the early and late received samples, respectively, determine an early channel energy based on the first CIR estimate, determine a late channel energy based on the second CIR estimate, compute an update amount based on the early and late channel energies, and update the FFT window position based on the update amount. In another aspect, the receiver may perform time tracking with an inner time tracking loop (TTL) and an outer TTL. The receiver may update the FFT window position in coarse steps with the outer TTL and in fine steps with the inner TTL.Type: GrantFiled: June 28, 2010Date of Patent: April 9, 2013Assignee: QUALCOMM IncorporatedInventors: Shivratna G. Srinivasan, Michael L. McCloud, Remi J. Gurski, Sunil Kumar Kandukuri Narayana

Publication number: 20100322117Abstract: Disclosed are methods and apparatus for initial acquisition in a communication system, and in particular Time Division Duplex (TDD) systems such as those found in LTE. A disclosed method, for example, includes running a plurality of predetermined amplifier gain states for a low noise amplifier (LNA) during initial acquisition in a time division duplex (TDD) system, and determining acquisition of a received signal based on searching across the plurality of predetermined amplifier gain states. Forcing the amplifier gain into a set of predetermined gain states affords quicker resolution of initial acquisition for setting the gain of the LNA, which in TDD systems is complicated due to an uncertain uplink/downlink timeline that precludes continuous operation of a gain setting algorithm run in the LNA.Type: ApplicationFiled: June 8, 2010Publication date: December 23, 2010Applicant: QUALCOMM INCORPORATEDInventors: Remi J.
