Publication number: 20120157074Abstract: Prior to being admitted into the network, a base station establishes a set of operating parameters. Next, a search is performed to determine the presence and configuration of neighboring base stations and current network conditions. Based on the search results, an improved operating configuration is determined for the base station and the base station's operating parameters are adjusted. Once the base station is admitted to and is operating in the network, the base station continues to monitor neighboring base stations and network conditions and adjusts its operating parameters accordingly.Type: ApplicationFiled: February 14, 2012Publication date: June 21, 2012Applicant: INTERDIGITAL TECHNOLOGY CORPORATIONInventors: Janet Stern-Berkowitz, Charles Dennean

Publication number: 20110243066Abstract: Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.Type: ApplicationFiled: October 1, 2010Publication date: October 6, 2011Applicant: InterDigital Patent Holdings, Inc.Inventors: Shahrokh Nayeb Nazar, Kyle Jung-Lin Pan, Robert L.

Patent number: 7978658Abstract: In a wireless communication system using a reference channel used for error rate measurement and associated with a plurality of transport channels multiplexed on a coded composite transport channel (CCTrCH), a method is employed for reselection of the reference channel from favorable candidate transport channels. A channel is initially selected from the plurality of multiplexed channels as the reference channel. Channels are monitored based on quantitative data content criteria to determine whether an ON or OFF state exists. A different channel is selected from the plurality of multiplexed channels as the reselected RTrCH when a better candidate transport channel in the ON state becomes available, or when the monitored RTrCH reflects an OFF state.Type: GrantFiled: November 10, 2008Date of Patent: July 12, 2011Assignee: InterDigital Technology CorporationInventors: Pascal M.

Patent number: 7801548Abstract: A wireless communication system and method for controlling transmission power to maintain a received signal-to-interference ratio (SIR) as close as possible to a target SIR. A received quality is maintained as close as possible to a target quality based on block error rate (BLER). When a target BLER is converted to an initial target SIR, an error may occur due to a channel condition mismatch, since the target SIR required for the target BLER varies with channel conditions. An outer loop power control process is used to set a target SIR for each coded composite transport channel (CCTrCH) based on the required target BLER. The process adjusts a SIR step size parameter to maximize the convergence speed of the process.Type: GrantFiled: August 9, 2007Date of Patent: September 21, 2010Assignee: InterDigital Technology CorporationInventors: Chang-Soo Koo, Sung-Hyuk Shin, Charles Dennean

Patent number: 7660600Abstract: A method for outer loop power control which compensates for changing channel conditions. A target metric, preferably target signal-to-interference ratio (SIR), is adjusted with differing step up and step down levels to converge on a relatively low steady state level of step up and step down target metric adjustments. The initial target SIR remains fixed during an inner loop settling state, followed by incremental target SIR adjustments during a transient state, and smaller incremental target SIR adjustments in a steady state. Step sizes of the adjustments are preferably based on the target block error rate (BLER) and the number of errors detected within predetermined time intervals.Type: GrantFiled: March 26, 2007Date of Patent: February 9, 2010Assignee: InterDigital Technology CorporationInventors: Chang-Soo Koo, Charles Dennean
