Patent number: 9185619Abstract: Methods and apparatuses are provided for mitigating interference among access points, and/or devices communicating therewith, in unplanned network deployments. Based on determining that one or more served devices potentially interfere with one or more access points, an inter-frequency handover (IFHO) threshold or data rate can be adjusted for the device to cause IFHO or reduce occurrence of interference, and/or a coverage area can be modified so the device can communicate with one or more other access points to mitigate potential interference. Based on determining interference from one or more devices served by other access points, an access point can switch operating modes to a hybrid or open access point to allow the one or more devices to handover to the access point, and/or can boost downlink transmit power to cause the one or more devices to perform IFHO from the other access points to mitigate potential interference.Type: GrantFiled: June 28, 2011Date of Patent: November 10, 2015Assignee: QUALCOMM IncorporatedInventors: Farhad Meshkati, Yan Zhou, Vinay Chande, Mehmet Yavuz

Publication number: 20150319702Abstract: A method or apparatus for configuring OLPC parameters for uplink communications in a cellular wireless network includes determining an estimated number of neighbor cells deployed within radio range of a cell, and configuring OLPC parameters for uplink communications, based on the estimated number of neighbor cells. Determining the estimated number of neighbor cells may include measuring respective signal strengths of the neighbor cells using network listen functionality. At least two OLPC intermediate parameters Po and ? may be selected from a data table, based on the estimated number of neighbor cells. A path loss statistic may be determined, based on UE measurement reports including path losses of UEs to itself and other cells. The OLPC parameters may be selected based on the path loss statistic and Po and ?, and/or adapted based on at least one of UE power headroom reports or overload indicators received from the neighbor cells.Type: ApplicationFiled: May 2, 2014Publication date: November 5, 2015Applicant: QUALCOMM INCORPORATEDInventors: Chirag Sureshbhai Patel, Vinay Chande, Liwen Yu, Tamer Adel Kadous

Patent number: 9179421Abstract: Methods and apparatuses are provided for determining a transmission power cap for one or more devices based at least in part on pathloss measurements to one or more access points received from the one or more devices. A common transmission power cap can also be computed for assigning to devices communicating with an access point, and the transmission power cap for a given device can be adjusted when the transmission power is at or a threshold level from the common power cap to conserve signaling in the wireless network. Adjustment of the transmission power cap can additionally or alternatively be based on a received power at an access point related to signals from the device, an interference report from one or more access points, and/or the like.Type: GrantFiled: February 2, 2015Date of Patent: November 3, 2015Assignee: QUALCOMM IncorporatedInventors: Yan Zhou, Farhad Meshkati, Vinay Chande, Mehmet Yavuz, Yi Jiang

Publication number: 20150282077Abstract: Systems and methods are provided for optimizing resource usage by a network entity that detects a first channel condition for a first radio access technology (RAT) and a second channel condition for a second RAT. The network entity determines whether the first channel condition comprises a higher interference level than the second channel condition and also determines power consumption constraints. If the first channel condition comprises a higher interference level than the second channel condition, the network entity reassigns at least one antenna from the first RAT to the second RAT based at least in part on the power consumption constraints. In some embodiments, systems and methods are also provided for determining whether an access point serving an access terminal is a large cell base station or a small cell base station and determining a power management action for the access terminal.Type: ApplicationFiled: March 28, 2014Publication date: October 1, 2015Applicant: QUALCOMM IncorporatedInventors: Mehmet Yavuz, Chirag Sureshbhai Patel, Tamer Adel Kadous, Vinay Chande

Patent number: 9137713Abstract: Methods and apparatuses are provided for causing active hand-in of a device from a macrocell base station to a femto node, which can be an inter-frequency hand-in. The femto node can broadcast a beacon over an operating frequency of the macrocell base station, and the macrocell base station, and/or one or more network components, can identify the femto node based on one or more parameters reported by the device from receiving the beacon. The beacon can be transmitted at varying powers to ensure active hand-in triggering, mitigate interference and/or can be powered on and off for such purposes. In addition, a macrocell base station can regulate compressed mode periods during which a device can measure the femto node based on receiving information regarding device proximity to the femto node, or a device can generate proximity indication messages base on measuring the beacon signals, etc.Type: GrantFiled: September 15, 2011Date of Patent: September 15, 2015Assignee: QUALCOMM IncorporatedInventors: Andrei Dragos Radulescu, Vinay Chande, Jen Mei Chen, Sanjiv Nanda, Damanjit Singh, Mehmet Yavuz

Patent number: 9055541Abstract: Transmit power for an access point is controlled based on information received by the access point. For example, an access point may employ one or more algorithms that use messages received from nearby access terminals to maintain an acceptable tradeoff between providing an adequate coverage area for access point transmissions and mitigating interference that these transmissions cause at nearby access terminals. Here, the access point may employ a network listen-based algorithm upon initialization of the access terminal to provide preliminary transmit power control until sufficient information is collected for another transmit power control algorithm (e.g., an access terminal assisted algorithm). Also, the access terminal may employ an active access terminal protection scheme to mitigate interference the access point may otherwise cause to a nearby access terminal that is in active communication with another access point.Type: GrantFiled: January 20, 2014Date of Patent: June 9, 2015Assignee: QUALCOMM IncorporatedInventors: Chirag Sureshbhai Patel, Mehmet Yavuz, Leonard Henry Grokop, Vinay Chande, Sanjiv Nanda, Farhad Meshkati, Sumeeth Nagaraja
