Patent number: 11381981Abstract: Methods, systems, and devices for wireless communications are described. In some systems, wireless devices operating in an unlicensed radio frequency spectrum band may perform directional listen-before-talk (LBT) procedures to gain access to a channel. In a beam-shrinking scheme for directional LBT, a wireless device may start an LBT procedure using a first beam (e.g., a wide beam). If the clear channel assessment (CCA) fails for the first beam (e.g., due to directional interference), the device may switch the LBT procedure to a second beam (e.g., a narrower beam). Depending on the direction of the interference source, the second beam may result in a successful LBT procedure. In a beam sweeping scheme for directional LBT, a wireless device may perform concurrent LBT over multiple narrow beams. If any beam of the set of beams detects frequent or continuous interference, the device may drop that beam from the concurrent LBT procedure.Type: GrantFiled: January 16, 2020Date of Patent: July 5, 2022Assignee: QUALCOMM IncorporatedInventors: Srinivas Yerramalli, Xiaoxia Zhang, Tao Luo, Arumugam Chendamarai Kannan, Vinay Chande

Patent number: 11356378Abstract: A credit return field is used in a credit-based flow control system to indicate that one or more credits are being returned to a sending device from a receiving device. Based on the number of credits available, the sending device determines whether to send device or wait until more credits are returned. A write enable mask allows a wide data field to be used even when a smaller amount of data is to be written. A novel data packet uses a combined write enable mask and credit return field. In one mode, the field contains a write enable mask. In another mode, the field contains credit return data. If the field contains credit return data, a default value (e.g., all ones) is used for the write enable mask. The mode may be selected based on another value in the data packet.Type: GrantFiled: August 31, 2020Date of Patent: June 7, 2022Assignee: Micron Technology, Inc.Inventors: Tony Brewer, David Patrick

Patent number: 11343666Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a wireless device may broadcast a discovery preamble to identify a receiving device or to identify a suitable beam for communicating with a receiving device prior to broadcasting a discovery message to the receiving device. In such systems, the wireless device may use the techniques described herein to generate the discovery preamble and to reduce interference between discovery preamble transmissions and avoid data loss. In one example, a wireless device may append a cyclic prefix (CP) to a discovery preamble with a suitable length to protect the discovery preamble from interference from another transmission. In another example, the wireless device may generate a cyclically periodic signal including multiple copies of the discovery preamble so a receiving device may be able to receive a portion of the signal and identify the discovery preamble.Type: GrantFiled: January 3, 2019Date of Patent: May 24, 2022Assignee: QUALCOMM IncorporatedInventors: Navid Abedini, Zhibin Wu, Junyi Li, Sudhir Kumar Baghel, Kapil Gulati, Libin Jiang
