Publication number: 20240007336Abstract: Devices and methods of using xSS are generally disclosed. A UE receives an xPSS with (Nrep) symbols each with a subcarrier spacing of K×a PSS subcarrier spacing and a duration of a PSS symbol/K. PSD subcarriers surround the xPSS and the ZC sequence is punctured to avoid transmission on a DC subcarrier. Guard subcarriers separate the xPSS and PSD when the ZC sequence is less than the occupied BW of the xPSS and at least one element in the ZC sequence is punctured for xPSS symbol generation otherwise. One or more xSSSs and xS-SCHs may follow the xPSS. The xSS may be omnidirectional, each having a same xPSS and different xSSS or xS-SCH or a different xPSS and same xSSS or xS-SCH or beamformed, each having different xPSSs and xSSSs or xS-SCHs or a same xPSS and different xSSS or xS-SCH.Type: ApplicationFiled: September 19, 2023Publication date: January 4, 2024Inventors: Seunghee Han, Gang Xiong, Jong-Kae Fwu, Huaning Niu, Utsaw Kumar

Patent number: 11606760Abstract: A radio node may transmit a signal using a transmit power. Then, the radio node may adjust the transmit power within a range of values. The adjustment may include reducing the transmit power when a spatial received signal strength indication (RSSI) metric of the radio node is greater than a first threshold value and a coverage criterion is met. Note that the spatial RSSI metric of the radio node may correspond to a set of temporal RSSI metrics of the radio node received from neighboring radio nodes. Moreover, the coverage criterion may be that less than a portion of RSSI measurements of the radio node associated with electronic devices, which are communicatively attached with the radio node, is less than a second threshold value. Alternatively, the adjustment may include increasing the transmit power when the spatial RSSI metric is less than the first threshold value.Type: GrantFiled: March 12, 2021Date of Patent: March 14, 2023Assignee: ARRIS Enterprises LLCInventors: Utsaw Kumar, Shailender Potharaju, Paul Petrus

Patent number: 11438872Abstract: Devices and methods of enhancing narrowband communications are generally described. NPSS and NSSS are modulated to include an additional bit that indicates a duplexing scheme, a raster frequency offset (zero or non-zero), an operating mode (in-band or standalone/guard-band) or frame timing used by the eNB. The NPSS modulation uses conjugate ZC sequences multiplied by a cover code for each OFDM symbol. The NMIB may provide additional information related to the operating mode or offset. NSSS cyclic shifts may be used to indicate the offset or TDD/FDD use, as may relative locations of the NPSS and NSSS. The NSSS may use symbol-level modulation and time domain cyclic shifts to indicate the frame timing.Type: GrantFiled: September 29, 2016Date of Patent: September 6, 2022Assignee: Intel CorporationInventors: Utsaw Kumar, Debdeep Chatterjee, Seunghee Han, Ralf Matthias Bendlin

Patent number: 11159355Abstract: A synchronization signal design is described for narrowband Internet of Things Communications. The synchronization signals facilitate time and frequency synchronization between an eNB and UEs. In one example, operations include generating an NB-Iot Secondary Synchronization Signal (N-SSS) using a Zadoff-Chu (ZC) sequence, scrambling the ZC sequence using a scrambling sequence, and transmitting the resulting scrambled NB-Iot Secondary Synchronization Signal (N-SSS) by the eNB in a periodic manner, wherein, the eNB has a cell identifier and the cell is identified by a combination of the root of the ZC sequence and the scrambling sequence.Type: GrantFiled: June 29, 2016Date of Patent: October 26, 2021Assignee: APPLE INC.Inventors: Utsaw Kumar, Seunghee Han, Debdeep Chatterjee, Ralf Bendlin

Publication number: 20210306925Abstract: A radio node in a network (such as a small cell) that receives predefined handover parameters is described. During operation, the radio node may receive, from a computer (such as a controller), information specifying the predefined handover parameters, where the predefined handover parameters correspond to a density of radio nodes in the network. For example, the radio node may provide, to the computer, information specifying the density of radio nodes in the network. Moreover, the radio node may receive, from the electronic device, information specifying a communication-performance metric associated with the radio node. Next, the radio node may provide, to the electronic device, a recommendation for a handover from the radio node to another radio node in the network based at least in part on the predefined handover parameters, the communication-performance metric and a second communication-performance metric associated with the other radio node.Type: ApplicationFiled: March 25, 2021Publication date: September 30, 2021Inventors: Awaiz Ahmad Khan, Utsaw Kumar

A first UE of the UEs can be scheduled to generate uplink transmissions from PRBs within the NOMA zone without an explicit grant message based on predefined threshold of a first transmission packet size or a first transmission rate. Another UE can also be scheduled to utilize resources of the NOMA zone or the OMA zone based on the predefined threshold.Type: GrantFiled: November 30, 2016Date of Patent: February 11, 2020Assignee: Apple Inc.Inventors: Utsaw Kumar, Hwan-Joon Kwon
