Patent number: 8989081Abstract: When wireless systems are in communication with each other, transmit power levels can vary based on a distance between the communicating wireless systems. The transmit power levels may be varied by taking into consideration optimal values of performance indicators such as SNR. However, because a transmitting wireless system typically does not receive information that describes a communication channel as seen by a receiving wireless system, the transmitting wireless system may not be able to accurately determine when, whether, and by how much to reduce the transmit power without impairing signal reception ability at the receiving wireless system. Functionality can be implemented on the transmitting wireless system to vary the transmit power level based on comparing a percentage of packets transmitted at a maximum packet transmit rate with one or more thresholds. Such a variation of the transmit power levels can help reduce power consumption and ensure performance is not compromised.Type: GrantFiled: March 18, 2013Date of Patent: March 24, 2015Assignee: QUALCOMM IncorporatedInventors: Susinder R.

Patent number: 8983524Abstract: A method and apparatus are described for controlling transmitter power in a wireless communication system in which both dedicated and shared channels are utilized. A wireless transmit/receive unit (WTRU) may receive a first channel (e.g., downlink shared channel), power commands for a second channel (e.g., dedicated channel) and power commands for a third channel (e.g., uplink shared channel). The WTRU may transmit in a transmission time interval at least one of the second channel and the third channel. Acknowledgments and negative acknowledgements to signals received over the first channel may be sent on the third channel. The WTRU may determine a transmission power level of the second channel in response to the second channel power commands and not the third channel power commands. The WTRU may determine a transmission power level of the third channel in response to the third channel power commands and not the second channel power commands.Type: GrantFiled: April 9, 2014Date of Patent: March 17, 2015Assignee: InterDigital Technology CorporationInventors: Stephen G.

Patent number: 8982756Abstract: An intermittent reception control apparatus controls intermittent reception in communication between a base station apparatus and mobile station apparatuses. The intermittent reception control apparatus comprising a control unit that generates DRX parameters, which are intermittent reception parameters, and transmits the generated DRX parameters to the mobile station apparatuses. Further, the DRX parameters include information on the timing at which to cause the mobile station apparatuses to enter an active state and are common to all of the mobile station apparatuses, where the active state is a state where reception of signals transmitted from the base station apparatus is enabled. The intermittent reception control apparatus further comprising a scheduler that transmits to the mobile station apparatuses a DRX command that operates to force these apparatuses to enter an inactive state.Type: GrantFiled: January 18, 2013Date of Patent: March 17, 2015Assignee: Fujitsu LimitedInventors: Toru Imamura, Kiyoshi Miyazawa, Yoshiyuki Oota, Syuuichi Okada, Hiroaki Takashima

Patent number: 8982774Abstract: A network based positioning (NBP) system is disclosed that allows any of its access points (APs) to initiate ranging operations with a station device (STA), regardless of whether the STA is in power save mode and regardless of whether a particular AP is currently associated with the STA. For example, to initiate ranging operations with the STA from a non-associated AP, the non-associated AP obtains the TSF timer of the associated AP, and then uses the obtained TSF timer to derive the associated AP's beacon transmission schedule and thereby determine when the STA's corresponding wake-up periods occur. Thereafter, the non-associated AP can initiate ranging operations with the STA during the STA wake-up periods, thereby ensuring that probes sent from the non-associated AP will arrive at the STA while the STA is awake from power save mode.Type: GrantFiled: June 27, 2012Date of Patent: March 17, 2015Assignee: QUALCOMM IncorporatedInventors: Purushotham Kamath, Vijay Kumar Dewangan, Praveen Dua

Patent number: 8977308Abstract: Apparatuses and methodologies are described that mitigate signal pollution in a wireless communication system. According to one aspect, user devices can request signals for use in access point selection. Access points can be selected based upon the received strength of their signals. In one aspect, access points can delay the transmission of signals based upon the strength of the received request. In addition, if sufficient access points respond during the delay, an access point can refrain from transmitting signals in response to signal requests, further reducing signal pollution.Type: GrantFiled: February 22, 2006Date of Patent: March 10, 2015Assignee: QUALCOMM IncorporatedInventor: David Jonathan Julian

Patent number: 8977876Abstract: An apparatus for implementing low power consumption for data switching device includes a dormancy management module that controls an upper layer logic component in a device to enter a low power consumption state when a current state parameter of the device satisfies a preset dormancy configurationcondition; detects whether an energy consumption state of a transmission medium is active; and wakes up the upper layer logic component in the device to enter a normal working state if the energy consumption state of the transmission medium is active. When a preset condition is satisfied, upper layer logic components such as a CPU, a network processor and an optical module in the device, properly stop full-time operation to save energy.Type: GrantFiled: March 14, 2013Date of Patent: March 10, 2015Assignee: Huawei Technologies Co., Ltd.Inventors: Xueren Yang, Jianzhao Li, Wen Xiao, Yong Wang
