Publication number: 20230300675Abstract: This application provides an uplink data splitting method, a terminal device, and a chip system, and relates to the field of communication technologies. The method includes the following: After determining that a timer expires, a terminal device determines, based on transmission capabilities of an LTE link and an NR link, a data amount of a data package transmitted on the LTE link and the NR link. The transmission capability of the LTE link is determined by the terminal device by transmitting a first detection data package on the LTE link before the timer expires. The transmission capability of the NR link is determined by the terminal device by transmitting a second detection data package on the NR link before the timer expires. The second detection data package is obtained through duplication based on the first detection data package. The terminal device sends same data packages to different communication links to detect transmission capabilities of the communication links.Type: ApplicationFiled: July 7, 2021Publication date: September 21, 2023Inventors: Guibin Lin, Xiaojun Sun, Feng Qian

Publication number: 20230192090Abstract: Among other things, techniques are described for determining precedence order at a multiway stop. In embodiments, identifications are assigned to tracks, and young tracks are compared to stale tracks. A young track matches a stale track based on one or more factors. An identification of the young track is reassigned to an identification of the stale track, wherein the young track is determined to match the stale track based on the one or more factors. An earliest time of appearance of agents is determined based on identifications and in view of perception obscured areas. A precedence order for navigating through the intersection is determined based on local rules, the identifications, and the earliest time of appearance of agents, and the vehicle proceeds through the multiway stop intersection in accordance with the precedence order.Type: ApplicationFiled: January 25, 2022Publication date: June 22, 2023Inventors: Scott D.
