Patent number: 10237032Abstract: In mixed numerology case, the performance of a physical downlink shared channel (PDSCH) can be improved by multiplexing PDSCH of one numerology with the channel state information reference signals (CSI-RS) of the other numerology and use of an advanced receiver. However, due to the interference from the PDSCH of the other numerology, the channel estimation for the underlying UE can be impacted if the CSI-RS is corrupted. An adaptive CSI-RS configuration can be deployed where the CSI-RS density is adapted based on the PDSCH transmission of the other numerology. Namely, based on the scheduling decision of the other numerology, the CSI-RS density can be changed. Thus, the impact on channel estimation can be minimized when the data channel of one numerology is multiplexed with the CSI-RS of the other numerology.Type: GrantFiled: January 6, 2017Date of Patent: March 19, 2019Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: SaiRamesh Nammi, Xiaoyi Wang, Arunabha Ghosh

Patent number: 10129412Abstract: A system, apparatus, and methods are provided for establishing and supporting a VOIP (Voice Over Internet Protocol) call from one computing/communication device to another. The system receives a call offer from a caller, forwards it to the callee, and identifies to each party multiple candidate relay entities for relaying their digitized voice communications. Each device binds with one or all relays, and either or both of them select one of the relays to use in a relay mode of operation of the call, if necessary. One or more of the relays inform the devices of their external network addresses, and each device passes its (internal and external) addresses to each other, through the system. The devices attempt to establish a direct connection to conduct their call in a peer-to-peer mode of operation, but may dynamically switch between peer-to-peer and relay modes as necessary.Type: GrantFiled: September 8, 2014Date of Patent: November 13, 2018Assignee: WHATSAPP INC.Inventors: Manpreet Singh, Ehren A.
