Patent number: 8792407Abstract: A wireless communications power saving method and apparatus is provided. The method includes, when no reverse link traffic exists and no forward link traffic has been received for a predetermined amount of time, establishing, at a terminal, a reverse link transmission pilot signal duty cycle, and boosting overhead channel signal transmission power during ON slots and gating overhead channel and pilot signal transmission power during OFF slots. The design further includes estimating, at the terminal, an available data transmission rate, determining an actual data transmission rate, setting a terminal transmission duty cycle for a next period based on the estimated available data transmission rate, the actual data transmission rate, and a margin of error, and transmitting data from the terminal according to the terminal transmission duty cycle.Type: GrantFiled: February 21, 2012Date of Patent: July 29, 2014Assignee: Qualcomm IncorporatedInventors: Jun Hu, Donna Ghosh, Christopher G.

Patent number: 8774208Abstract: Some implementations of the present invention provide mechanisms for gating the transmission of FIN and other short overhead messages of the like in order to improve spectral efficiency. In some implementations spectral efficiency is improved by reducing the number of air-link connections established to merely transmit FIN and other short overhead messages of the like. In one implementation FIN messages are buffered in a queue and transmitted when an air-link connection is established to transmit higher value messages. In one implementation FIN messages are buffered and transmitted when the contents of the buffer breach a threshold that justifies the establishment of an air-link connection to transmit the contents of the buffer.Type: GrantFiled: September 14, 2011Date of Patent: July 8, 2014Assignee: QUALCOMM IncorporatedInventors: Rashid Ahmed Akbar Attar, Christopher Gerard Lott, Donna Ghosh, Linhai He, George Cherian

Publication number: 20140105085Abstract: Access terminals are adapted to facilitate discontinuous transmission (DTX). According to one example, an access terminal can employ a short timescale DTX mode and a long timescale DTX mode independent of one another. The access terminal can determine whether a first set of predetermined factors are present. When the first set of factors are determined to be present, the access terminal may enable a short timescale DTX mode, independent of whether a long timescale DTX mode is enabled or not. A determination may also be made whether a second set of predetermined factors are present. When the second set of predetermined factors are determined to be present, the access terminal may enable a long timescale DTX mode, independent of whether the short timescale DTX mode is enabled or not. Other aspects, embodiments, and features are also included.Type: ApplicationFiled: February 26, 2013Publication date: April 17, 2014Applicant: QUALCOMM IncorporatedInventors: Jun Hu, Rashid Ahmed Akbar Attar, Donna Ghosh, Christopher Gerard Lott, Linhai He

Patent number: 8553712Abstract: Carrier management in a wireless communication device assigned a set of two or more carriers by a wireless communication network is disclosed. In one aspect, a method of carrier management includes transmitting data over the wireless communication network on one or more carriers forming a subset of active carriers from the set of carriers assigned to the wireless communication device. A first performance metric is determined indicative of operating conditions across the set of carriers assigned to the wireless communication device.

The desired number of carriers on which to transmit data is compared with the number of carriers in the subset of active carriers. The subset of active carriers is dynamically adjusted based on the comparison and subsequent data is transmitted over the wireless communication network using the adjusted subset of active carriers.Type: GrantFiled: January 29, 2009Date of Patent: October 8, 2013Assignee: Qualcomm IncorporatedInventors: Donna Ghosh, Qingxin Chen, Christopher Gerard Lott, Jun Hu, Ravindra Garach, Rashid Ahmed Akbar Attar
