Publication number: 20240137971Abstract: An extremely high throughput (EHT) station (STA) configured for trigger based (TB) transmission may decode an trigger frame (TF) received from an access point (AP). The TF may include an assignment of resources comprising one or more 20 MHz channels. The EHT STA may determine which of the one or more assigned channels are available for transmission and which of the allocated channels are unavailable when the EHT STA is assigned more than one 20 MHz channel. The EHT STA may encode a EHT TB PPDU in response to the trigger frame. The EHT TB PPDU may be encoded to include an EHT preamble followed by a data field. The EHT preamble may be encoded to indicate channel availability. The EHT STA may generate signalling to cause the EHT STA to transmit the encoded EHT TB PPDU only on the assigned channels that have been determined to be available.Type: ApplicationFiled: August 29, 2023Publication date: April 25, 2024Inventors: Xiaogang Chen, Qinghua Li, Feng Jiang, Ziv Avital, Po-Kai Huang

Patent number: 11967779Abstract: Disclosed are a single-frequency circular polarization positioning antenna and a wearable device. The single-frequency circular polarization positioning antenna includes an inverted F antenna and a parasitic antenna which are in an orthogonal layout; resonance is generated on the parasitic antenna through a coupling effect by means of feeding the inverted F antenna, so that the overall structure of the circular polarization antenna is simplified, and is achieved on a wearable product more easily. Therefore, the positioning antenna can better receive signals of a navigation satellite, and right hand circular polarization radiation generated by an annular radiating body can also filter left hand circular polarization navigation satellite signals reflected by high buildings or the ground, so as to reduce the multipath interference, thus effectively improving the positioning accuracy of the positioning antenna of the wearable device.Type: GrantFiled: November 25, 2022Date of Patent: April 23, 2024Assignee: GUANGDONG GENIUS TECHNOLOGY CO., LTD.Inventors: Qinghua Jiang, Xiao Zhang, Bo Mei, Zengpei Zhong, Qiyu Zeng
