Publication number: 20240014852Abstract: Systems and methods for reduced interpath interference for ultrawideband (UWB) wireless communication are disclosed. In one aspect, a wireless communication device employs a systematic and non-random pulse-hopping scheme to introduce variable distances between pulses to reduce collision rates from interpath interference. In exemplary aspects, the scheme optimizes avoidance of collision rates for distances between paths of up to thirty nanoseconds (30 ns). The use of an optimized grid will be stable regardless of position of the user, thereby avoiding transmission drops and improving the user experience.Type: ApplicationFiled: June 29, 2023Publication date: January 11, 2024Inventors: Jaroslaw Niewczas, Michael McLaughlin

Patent number: 10673555Abstract: In an ultra-wideband (“UWB”) communication system comprising a pair of UWB transceivers, methods for securely performing channel sounding. In a first GCP Sync method, a pre-determined set of Golay Complementary Pairs is added to an 802.15.4a frame. In a second CLASS method, a cyphered low auto-correlation sum set is added to frame. In a third LCSSS method, a low cross-correlation sidelobe sum set is added to the frame. In general, these methods are adapted to transmit a pseudo-randomly generated codeset which may have inherent sidelobe distortions, and then, in the receiver, to compensate for this, and any channel-induced, distortion by selectively modifing the cross-correlation codeset.Type: GrantFiled: July 23, 2018Date of Patent: June 2, 2020Assignee: DecaWave, Ltd.Inventors: Ciaran McElroy, Jaroslaw Niewczas, Michael McLaughlin, Igor Dotlic, Marcas O'Duinn, Dries Neirynck

Patent number: 9615247Abstract: The embodiments herein relate to a method in a base station (101) for transmitting a transport block to a user equipment (105) in a communications network (100). The transport block comprises a plurality of bits. The base station (101) selects (203a, 203b, 401) a transport format. The base station (101) dynamically selects (204a, 203b, 402) a first redundancy version parameter based on a decoding performance for the transport block. The base station (101) transmits (205a, 204b, 404) the transport block comprising the plurality of bits distributed according to the dynamically selected first redundancy version parameter and according to the selected transport format in a first transmission to the user equipment (105).Type: GrantFiled: January 22, 2013Date of Patent: April 4, 2017Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Jaroslaw Niewczas, Andreas Cedergren, Andres Reial
