Patent number: 9769003Abstract: This application presents a direct data recovery from subspaces or parameters subranges of a received OFDM signal preidentified as corresponding to specific data symbols, by applying adaptive inverse signal transformation (AIST) method for reversing both original data coding and deterministic and random distortions introduced by a transmission channel, wherein both reversals are achieved by the same conversion of the subspaces or parameter subranges into data transmitted originally in order to eliminate an intermediate recovery of signals or parameters transmitted originally within the received OFDM signal. The AIST includes using both amplitudes and gradients of amplitudes of OFDM tone signals.Type: GrantFiled: July 9, 2015Date of Patent: September 19, 2017Inventor: John W Bogdan

Patent number: 9763158Abstract: A user equipment (UE) speeds up circuit switched fallback call establishment and reduces circuit switched fallback call establishment failure. In one instance, the UE receives a redirection command including a list of current neighbor cells/frequencies. The UE determines whether a current serving cell matches a previous serving cell stored in the UE. The UE also evaluates the list of current neighbor cells to determine whether each current neighbor cell matches a previous neighbor cell associated with the previous serving cell. The UE then determines neighbor cells for power scan and/or synchronization channel decoding procedures to select one of the current neighbor cells to redirect the UE based on the previously recorded type of redirection result.Type: GrantFiled: January 13, 2016Date of Patent: September 12, 2017Assignee: QUALCOMM IncorporatedInventors: Ming Yang, Tom Chin

Patent number: 9722717Abstract: Technologies for robust data transmission include a network port logic having a physical coding sublayer (PCS). The PCS may transmit a series of rapid alignment markers (RAMs) to a link partner, with each RAM indicative of a counter value. The PCS transitions to a sleep state if the counter value equals two and a low power idle (LPI) command is set by an upper-layer client. The PCS transitions to an active state if the counter value equals one and the LPI command is not set. The PCS may receive a low power idle symbol (LI) from the link partner and start a guard timer in response to receipt of the LI symbol. The PCS transitions to a sleep state if the guard timer expires and transitions to the active state if data other than LI is received prior to expiration of the guard timer. Other embodiments are described and claimed.Type: GrantFiled: December 18, 2014Date of Patent: August 1, 2017Assignee: Intel CorporationInventors: Yoni Landau, Assaf Benhamou, Adee O. Ran

Patent number: 9713099Abstract: Various of the disclosed embodiments improve the operations of a combined access point/Cable modem. Though the access point component and the Cable modem component may perform operations in different spectrums, harmonics in the Cable spectrum may interfere with operations, e.g., in the 2.4 GHz and 5 GHz range, of the access point. Some embodiments implement a remediation and/or channel transition process for the access point following detection of Cable-related interference. During remediation, the device may, e.g., adjust the wireless power levels, EDCA backoff times, signal thresholds, etc. In some embodiments, if the remediation actions prove ineffective, the wireless peers may be relocated to a channel further from the interfering Cable harmonics. The determination to remediate or reallocate may be based on various contextual factors, e.g., the character of the peer devices and the applications being run.Type: GrantFiled: December 16, 2014Date of Patent: July 18, 2017Assignee: NETGEAR, INC.Inventors: Joseph Amalan Arul Emmanuel, Peiman Amini, Shahrokh Mehroziad Zardoshti
