Publication number: 20200287759Abstract: This disclosure provides methods, devices and systems for identifying wake-up signals. Some implementations more specifically relate to PHY preamble designs for wake-up signals such as Wake-Up Radio (WUR) packets conforming to IEEE 802.11ba. In some implementations, the preamble designs can include a combination of modulation schemes, data rate indications and length indications enabling devices capable of receiving and decoding wake-up signals to identify the signals as wake-up signals (for example, WUR packets), while ensuring that devices not capable of receiving and decoding wake-up signals identify the wake-up signals as legacy packets, or otherwise not WUR packets.Type: ApplicationFiled: March 2, 2020Publication date: September 10, 2020Inventors: Didier Johannes Richard VAN NEE, Geert Arnout AWATER, Maarten Menzo WENTINK, Albert VAN ZELST, Bin TIAN, Stephen Jay SHELLHAMMER, Nitin RAVINDER, Muhammed Faruk GENCEL

Patent number: 10742472Abstract: This disclosure provides methods, devices and systems for encoding data for wireless communication to achieve a desired amplitude distribution. Some implementations more specifically relate to performing an encoding operation to shape the amplitudes of the resultant symbols such that the amplitudes have a non-uniform distribution. In some implementations of the non-uniform distribution, the probabilities associated with the respective amplitudes generally increase with decreasing amplitude. In some implementations, the first encoding operation is or includes an arithmetic encoding operation, a prefix encoding operation or other encoding operation that adds redundancy to the input data bits by expanding the number of data bits. The redundancy may be added such that the probabilities associated with encoding input data bits into symbols with lower amplitudes are greater than the probabilities associated with encoding input data bits into symbols with higher amplitudes.Type: GrantFiled: September 6, 2019Date of Patent: August 11, 2020Assignee: QUALCOMM IncorporatedInventor: Didier Johannes Richard Van Nee

Patent number: 10652924Abstract: Systems and methods are disclosed for a wireless device to transmit or receive a channel busy time (CBT) to or from other devices in a wireless network. For transmitting, the wireless device may determine a CBT during which a wireless channel is to be occupied, generate a universal reservation signal (URS) indicating the CBT, and transmit on the wireless channel the URS to at least one other wireless device. For receiving, the wireless device may receive on a wireless channel a URS from a second wireless device, the URS configured to indicate the CBT. The wireless device may also refrain from attempting to transmit on the wireless channel during the CBT.Type: GrantFiled: July 18, 2018Date of Patent: May 12, 2020Assignee: Qualcomm IncorporatedInventors: Maarten Menzo Wentink, Didier Johannes Richard Van Nee, Albert Van Zelst, Bin Tian, Hemanth Sampath

Publication number: 20200145139Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a retransmission protocol in a wireless local area network (WLAN). The retransmission protocol enables a sending station (STA) to communicate additional parity bits associated with an original transmission that included forward error correction (FEC) encoded codewords. Several techniques are described for a receiving STA to indicate which portions of the original transmission was not properly received. The receiving STA may store the original transmission for use with additional parity bits in a subsequent transmission. The sending STA may communicate the additional parity bits in a subsequent transmission to assist the receiving STA recover the data from the original transmission.Type: ApplicationFiled: November 1, 2019Publication date: May 7, 2020Inventors: Simone Merlin, Didier Johannes Richard Van Nee, Hemanth Sampath, Bin Tian, Gwendolyn Denise Barriac

Publication number: 20190342828Abstract: Methods, systems, and devices for wireless communications are described. An access point (AP) may identify a sequence of on symbols and off symbols for transmission to a wake-up radio (WUR) of a wireless device. The AP may assign a modulation symbol from a set of possible modulation symbol waveforms to at least each on symbol in the sequence. The modulation symbol waveforms may be assigned to sequential on symbols in a random or pseudorandom order, e.g., by applying a random phase rotation to a stored modulation symbol waveform, by applying a random cyclic shift to a stored modulation symbol waveform, or by applying a random or pseudorandom phase-shift keying value to each subcarrier in a multicarrier system to generate a modulation symbol waveform. The AP may transmit the sequence to the WUR based at least in part on the assigned modulation symbol waveforms.Type: ApplicationFiled: April 29, 2019Publication date: November 7, 2019Inventors: Stephen Jay Shellhammer, Didier Johannes Richard Van Nee, Bin Tian

Patent number: 10153933Abstract: Techniques are provided for constructing or determining a training sequence as a part of transmission preamble to minimize (or at least reduce) a peak-to-average power ratio (PAPR) at a transmitting node. In one example, a long training field (LTF) sequence of a preamble is determined that combines a set of interpolating sequences with LTF tone values. The LTF tone values may cover at least a portion of bandwidth of a first size, with each of the LTF tone values repeated for different subcarriers. The phases of tones of the LTF sequence may be rotated per bandwidth of the first size and certain tones of the LTF sequence may have a stream of values at pilot locations. For example, the phases of tones of the LTF sequence may be rotated in an effort to reduce PAPR during a transmission of the LTF sequence.Type: GrantFiled: April 6, 2017Date of Patent: December 11, 2018Assignee: QUALCOMM IncorporatedInventors: Lin Yang, Didier Johannes Richard Van Nee, Hemanth Sampath
