Publication number: 20210400690Abstract: In some examples, a network node receives, from a first user equipment (UE), a report indicating that the first UE received a proximity beacon from a second UE and indicating a transmission opportunity during which the proximity beacon was received. In response to receiving the report at the network node, the network node transmits, to the first UE, an identity associated with the second UE according to contents of the proximity beacon.Type: ApplicationFiled: July 26, 2021Publication date: December 23, 2021Inventors: Robert Novak, Biswaroop Mukherjee, Masoud Ebrahimi Tazeh Mahalleh

Patent number: 11082998Abstract: A method for communication in a wireless telecommunications system is provided. The method comprises receiving, by a first User Equipment (UE), a reference signal transmitted by a second UE and transmitting, by the first UE to a network node, a report indicating that the reference signal was received. The reference signal is received in a detection opportunity that occurs as one of a single detection opportunity or a portion of a pattern of detection opportunities.Type: GrantFiled: December 5, 2019Date of Patent: August 3, 2021Assignee: BlackBerry LimitedInventors: Robert Novak, Biswaroop Mukherjee, Masoud Ebrahimi Tazeh Mahalleh

Publication number: 20210021364Abstract: A system and method for permuting known and unknown message bits before encoding to provide a beneficial rearrangement of bits. Such a method can improve distance properties in the resulting subcode. In various embodiments, the structure of a beneficial rearrangement is dependent on the parameters of how known and unknown bits are grouped and on the specific type of code being used. Given these two parameters, the message bits can be rearranged to more efficiently leverage any apriori knowledge.Type: ApplicationFiled: October 6, 2020Publication date: January 21, 2021Inventors: Michael Eoin Buckley, Sean Bartholomew Simmons, Nathaniel Joseph Karst, Youn Hyoung Heo, Zhijun Cai, Andrew Mark Earnshaw, Masoud Ebrahimi Tazeh Mahalleh, Mo-Han Fong

Patent number: 10484131Abstract: Client data bits, including first client data bits and second client data bits, are communicated from a transmitter to a receiver. At the transmitter, the first client data bits are processed to generate processed values, where each processed value is more likely to be a first element than a second element. Forward Error Correction ‘FEC’ encoding is applied to the second client data bits to generate FEC-encoded values. Symbols are created by mapping the FEC-encoded values to first positions in the symbols and by mapping the processed values to second positions in the symbols. The symbols are modulated onto a communications channel using a modulation scheme with a code that assigns a lower average energy to symbols containing the first elements in the second positions than to symbols containing the second elements in the second positions. At the receiver, client data bits are decoded using conditional chain decoding.Type: GrantFiled: December 14, 2017Date of Patent: November 19, 2019Assignee: CIENA CORPORATIONInventors: Shahab Oveis Gharan, Mohammad Ehsan Seifi, Masoud Ebrahimi Tazeh Mahalleh, Kim B.

Patent number: 10075954Abstract: Systems, methods, and apparatuses for using band-limited subframes in wireless communication networks are provided. During the band-limited subframes, the macro cell base station may mute its transmission or transmit at a low power over some frequency sub-band, while transmitting at a normal or higher power over other frequency sub-band. Correspondingly, the small cell base station may communicate with UEs within its coverage at the frequency sub-band that the macro cell base station transmits at a low power. The band-limited subframe enables the small cell base station to communicate with the UE with reduced interference, and in the meantime, increases the throughput of macro cell base station as it does not require the macro cell base station to completely mute its transmission during the band-limited subframe.Type: GrantFiled: September 20, 2013Date of Patent: September 11, 2018Assignee: Blackberry LimitedInventors: Vahid Pourahmadi, Yongkang Jia, Yi Song, Siva Dharshan Muruganathan, Yufei Wu Blankenship, Hua Xu, Robert Mark Harrison, Shiwei Gao, Masoud Ebrahimi Tazeh Mahalleh
