Patent number: 12262406Abstract: Uplink transmissions of a mobile device (UE) may be improved in a number of ways. Uplink Transmission Time Interval (TTI) bundling, including both Type-A and Type B PUSCH repetitions, may be implemented with variable TTI bundle sizing. The TTI bundle size may be determined by a base station and communicated to the UE explicitly, or may be determined by the UE implicitly, based on an indicated repetition number and frequency hopping number. The UE may also report frequency hopping (FH) assist information to the base station for use by the base station to more efficiently configure FH for the uplink transmissions.

The BLE device is configured to scan for a preamble of a packet while in a first power mode and detect when a bit of the preamble is received. Upon detecting that the bit of the preamble is received, the BLE device switches from the first power mode to a second power having a higher operating power for the BLE device than the first power mode. The switch in power modes occurs while the preamble is being received or immediately after the preamble is received and before an access address of the packet is received. The BLE device, while in the second power mode, then scans for the access address of the packet.Type: GrantFiled: March 27, 2020Date of Patent: May 10, 2022Assignee: QUALCOMM INCORPORATEDInventors: Seyed Mohammad Ehsan Hosseini, Le Nguyen Luong, Eunmo Kang, Dongsik Kim

Patent number: 11211996Abstract: A technique for Bluetooth wireless communication is described. According to one aspect of the technique, Bluetooth data from a data source is received in a first wireless device through an antenna and a Bluetooth radio frequency transceiver thereof via a Bluetooth connection with the data source. The Bluetooth data is used to generate a modulation signal according to a narrowband orthogonal multi-carrier modulation technology. The modulation signal is transmitted to a second wireless device through the antenna and the Bluetooth radio frequency. The antenna and the Bluetooth radio frequency transceiver are time-multiplexed by the Bluetooth connection between the first wireless device and the data source, and the wireless connection between the first wireless device and the second wireless device. The described technique can be advantageously used for expanding the distance of Bluetooth wireless propagation of Bluetooth devices.Type: GrantFiled: April 14, 2020Date of Patent: December 28, 2021Assignee: Nanjing Zgmicro Company LimitedInventor: Bin Xu

Patent number: 11190949Abstract: A base station, e.g., a CBSD, selects or more user equipment (UE) devices, e.g., cell phones, to operate in monitoring mode. In monitoring mode the UE device, in addition to its normal communications with the base station, performs received power measurements in a frequency band, e.g., a CBRS band. The UE reports to the base station information indicating a UE determined measured power level attributed to incumbent user or measurement information used to derive a power level attributed to incumbent user. One or more base stations report received power measurement values attributed to incumbent user to a system management device, e.g., a SAS. The system management device processes the received information, e.g. combining information, and comparing a result to a threshold level. If the result exceeds the threshold the system management device sends a command to one or more base station to shut down DL traffic in the CBRS band.Type: GrantFiled: November 22, 2019Date of Patent: November 30, 2021Assignee: Charter Communications Operating, LLCInventors: Volkan Sevindik, Haider Syed
